Abstract

The invention relates to an exercise apparatus that comprises three main components: a vertical supporting member, a central supporting member and a platform. The vertical supporting member is a structure that has a base resting on the floor and, in the upper part thereof, is coupled to the upper end of the central supporting member in various positions. The lower end of the central supporting member rests on the floor, and the height at which the supporting members are coupled together determines the angle of tilt of the central supporting member. The central supporting member has rails on which the platform moves when pulled by a user by means of a cord passing through a series of pulleys and that has suitable securing elements. The apparatus of the invention allows small variations in the tilt of the central supporting member, by means of which variations adjustments are made to the force with which the exercise is performed, given that same is proportional to the angle of tilt. The apparatus has, furthermore, a system of pulleys that defines a path for the cord and allows the force with which the exercise is performed to be constant throughout exercising. Also described is an accessory that allows cardiovascular exercise to be performed.

The present apparatus is an apparatus for exercising. To exercise the person is positioned on the platform and pulls the ends of a rope through a pulley system causing a platform to move in an ascending path with a fixed angle. The opposing force to the movement of the exercise is provided by the weight of the person exercising and the weight of the platform.

The magnitude of the opposing force is modified by varying the angle at which the 'platform, travels upward.

Currently there are many such devices on the market, which have characteristics with deficiencies (areas of opportunity), which we will mention below: There is a variation in the opposing force to the exercise along the path of the platform, the force that it is exercised increases throughout the exercise and, an unequal exercise is caused.

The cause of this is because in the current designs there are two lateral pulleys in the central support and a central pulley in the platform, when the rope passes through the pulleys, the rope forms an angle. As the platform travels its ascending path, the central pulley of the platform approaches the side pulleys causing the angle that forms the rope to vary and this variation in the angle that forms the rope is the cause of variation of the opposing force to the exercise.

There is no way to vary the position of the handles with respect to the platform under tension conditions for a specific position of the platform. Not all exercises are the same, that is, for each different exercise, the starting point of the handles with respect to the platform and the end of the exercise are different, so it gives the apparatus a lot of versatility to be able to move the handles with respect to to the platform under tension conditions for a specific position of the platform. Additionally exercises even for two people with the same characteristics of ^'different height, require points different start and end.

The surface of the platform is always flat and for some exercises it is not ideal because the person is not positioned in an upright and balanced way. If the person is in a bad unbalanced position when performing a force exercise, the person is tensing muscle groups to maintain balance and it is most likely that the tensioning of these muscles will do so in a non-symmetrical way and can cause damage such as uneven development or even more serious complications such as scoliosis.

When positioning on the platform for certain exercises, the person has their feet in the air, this causes problems of balance and instability. For certain exercises it is very uncomfortable and problematic to pull the handles.

For example, in exercises to exercise the back it is much more comfortable to move the arms holding a bar instead of moving two handles. The variation of the angle of inclination of the platform's stroke is due to very large increases, which causes large increases in force to do the exercise.

The platform always has an upper limit and a lower limit when it comes to the race, which greatly limits and reduces exercise options. This is due to the fact that two people with different dimensional characteristics require different starting and termination points even for the same exercise, whereby the possibility of changing the upper and lower limits of the platform's stroke gives the device greater versatility .

In most exercise equipment of this type the pulleys are fixed in a position which limits the variety of exercises performed.

The configuration of the pulley system cannot be changed, so there is a variety of exercises that cannot be performed.

The weight with which the exercise is performed is limited to weight of the person and that of the platform, and in case of requiring more weight for the exercise the current designs offer minimum options.

Current designs only include aspects of muscle development in the apparatus and do not include aspects to exercise such as cardiovascular appearance.

In the current exercise apparatus the type of exercise that is performed is of a qualitative type (the force with which the exercise is executed is not known). The present invention overcomes the aforementioned deficiencies as it has the following characteristics:

It is an exercise apparatus that is composed of: a vertical support composed of a base in contact with the floor and a column that extends preferably vertically; a central support that has a lower end resting on the floor and an upper end coupled with the vertical support through the column, and which has left and right rails, and means for changing the height at which the central support is couples with the vertical support; A platform that moves. slidingly on the rails of the central support and on which the exercises will be carried out; support elements and fasteners both upper and lower for hands and feet, such as handlebars and pedals; at least one rope operatively coupled to a system of pulleys or sliding parts for ropes, the pulley system consists of at least one pulley or part coupled to the platform and at least one .par of pulleys or parts coupled to the central support ; the rope is coupled to the platform by means of the pulley or part of the system located on the platform so that when pulling the ends of the rope, the platform travels longitudinally on the rails of the central support; handles on the ends of the rope so that the person who exercises holds on to perform the corresponding exercise, where; The exercise apparatus has the following characteristics: the pulley or part system is such that it allows the force exerted during the exercise to be practically constant, and allows the position of the part or pulley located on the platform to be changed. such that the distance between it and the pulleys or parts placed in the central support can be varied without changing the position of the platform; mobile means for attaching an additional pulley or part on each side of the platform that allow the device to be configured to perform other exercises; the platform has adequate means to form a seat in which the entire surface thereof varies its angle and is placed in a practically horizontal position, so that the person who exercises can be seated in an upright and balanced manner; a detachable structure that allows the person who exercises to support the feet coupled to the part of the platform that can be placed horizontally; accessories for attaching the rope of the handles or the handles to the ends of a bar or a mechanism for performing cardiovascular type exercises; a system to place upper and lower stops to limit the platform's stroke; means for moving the pulleys coupled to the structure of the central support; simple means for assembly and disassembly that allow the device to be stored without taking up much space; means for modifying the force or exercise load in small increments between a minimum value and a maximum value, these values depend mainly on the weight placed on the platform and the weight of the platform and the coupling height between the vertical supports and central; means to measure the force during the execution of the exercise that make the apparatus of the quantitative type when knowing the magnitude of the force with which the exercise is exercised person .

The advantages offered by this new design are the following:

The force exerted during the execution of the exercise is constant throughout the exercise, which gives a more uniform exercise. The reason why the force is constant during the execution of the exercise is because the direction in which the rope is pulled to move the platform is practically parallel to the direction of movement of the platform.

The position of the handles can be varied with respect to a fixed position of the platform as the latter has a pulley at the bottom that can change position, resulting in a greater versatility of the device to perform different types of exercises .

When the surface of the platform has a seat shape, the person who exercises can sit frontally or laterally for the execution of the exercise and maintain an upright and symmetrical position for certain types of exercises, which benefits the execution of the exercise and decreases the possibility of hurting the person who exercises. For cases in which the person keeps the legs in the air this causes additional effort and some instability, so having a device to support the feet helps stability and balance - when performing certain exercises

The present design has several options for attaching a bar to the rope or to the handles, which facilitates the execution of some exercises

By having smaller and controlled increases in strength, the device has greater versatility and can be better configured for the specific needs of each user and type of exercise.

It allows to limit the starting and ending point of the movement of the platform in such a way that the platform can be positioned in the best way for the execution of each exercise

Having the possibility of moving the position of the pulleys, it makes the device versatile as it can be adjusted to different exercises and to the characteristics of the person who exercises.

The pulley configuration of the device can be modified adding pulleys to the sides of the platform so that a variety of additional exercises can be performed.

By being able to add weight to the platform, you can increase the force necessary to do the exercise without being limited to the weight of the platform and the weight of the person.

It has a device to perform cardiovascular • type exercises, making it a more complete and versatile exercise device.

The force that is performed when executing the exercise is known, ^' so the type of exercise that is performed is quantitative, since the weight that moves, the distance that moves and the number of repetitions that are performed are known .

Figure 1: shows in a generic way the present design. As shown in Figure 1, the apparatus consists of three main elements: the vertical support (1), the central support (2), and the platform (4); each of which consists of several components. You can see some of these components and other additional elements such as: rails (3), rope (8), pulleys (9), and handles (10) at the ends of the rope.

In figure 1 the pulleys, rails and handles are identified in a generic way, but in front of they will describe in more detail different modalities and will be identified with the corresponding number This exercise apparatus works as follows: The apparatus has the characteristic that to exercise the individual pulls the ends of a rope through a series of pulleys with which the platform moves. The person who exercises is positioned on the platform, which has at least four wheels and is mounted on the rails. The force with which the person is exercised is that which is necessary to move the platform and the person along the rails. To vary the force with which the person is exercised, the angle formed by the central support and the floor is varied; the greater the angle, the greater the force applied by the person to exercise. The variation of the angle is carried out by coupling the central support at different heights with the vertical support. There are several similar designs on the market, however the present design contains innovative elements described below.

With regard to vertical support, the design includes the following options. Figure 2 shows a type of vertical support that has the characteristic that is folded for easy storage. This vertical support of figure 2 shows the elements: base (11) which is the one that makes contact with the floor, and column (12) that is where the central support is connected, the base has an element that surrounds the bottom of the column (12) on three sides and it is with this element with which the column (12) has its pivot point. The column (12) rotates on the bolt (13) to remain in a horizontal position and that it can be stored without taking up much space, see figure 3. When the column (12) is in vertical position it is held in place by one or more bolts (14), a single bolt is shown in Figure 2 but may be more than one.

Figure 4 is a side view of the vertical support, in which the column (12) is held in place by one or more screws (15) and their corresponding nuts. Figure 4 only shows a nut and screw assembly, but you can have more than one screw and its corresponding nuts, the using screws provides greater rigidity to the assembly.

There is the modality in which the vertical support shown in the one described above (figures 2 and 4) is rigid and even if it does not change its shape for storage, if it fulfills its function in the exercise apparatus and has the advantage of having a piece of greater rigidity.

Figure 5 is a side view of the apparatus showing how the central support (2) is assembled with the vertical support (1). The central support has at the end that connects with the vertical support a fork-shaped piece (152) with holes (18) (see figure 6) which is assembled in the column

(12). The column (12) has holes (16) along it. The fork-shaped part (152) is assembled with the column (12) and is fixed in position through the bolt (17) which passes through the holes (18) of the fork-shaped part (152) and the holes (16) of the column (12). In this way and by a hinge type mechanism (19) the central support forms an angle (A) with the floor.

To vary the angle (A), the fork-shaped piece is moved along the column (12) by changing the hole (16) in which it is fixed with the bolt (17). Increasing the angle (A) increases the magnitude of the force to do the exercise.

The angle increase (A) depends on the vertical distance between the holes (16). In the case where minor increases are required and the holes cannot be approached

(16), a design shown in Figure 7 can be used where a column (153) is shown that has holes (21) that the separations between them are not only vertically, but also horizontally, thus being able to have separations between the holes (21) very small vertically without the risk of overlaps in the holes or very thin walls between holes.

Figure 7 shows three columns of holes, however this is not a limitation since they can be two or more columns. In the case of figure 7, the fork-shaped piece

(154) would be as shown in Figure 8, with three holes (22) at the same level, collinear and fixed in column (153) with a single bolt (20) in the most convenient position as shown in detail in figure 9. The number of holes of the fork-shaped part (154) and the number of vertical rows of column holes (153) should be the same and the horizontal separation of the holes in the column and the horizontal separation of the holes of the fork-shaped piece is the same.

Another modality is when the fork-shaped part is fixed (it does not have the hinge type mechanism) to the central support, for this case we will now describe how ^' the central support is coupled with the vertical support.

Figure 10 shows the aforementioned embodiment and for this case the fork-shaped end has a hole and the column (12) has a vertical row of holes (16) the fork-shaped end is assembled with the column ( 12) with bolt (157). In this case the central support will rotate using the center of the bolt (157) as the axis of rotation until the opposite end of the bolt makes contact with the floor, the central support will form an angle (C) with the floor.

To vary the angle (C) the ^'piece moves forked along the column (12) by changing the hole (16) which is fixed with the bolt (157). Increasing the angle (C) increases the magnitude of the force to do the exercise.

The angle increase (C) depends on the vertical distance between the holes (16). In the case where minor increases are required and the holes cannot be approached

(16), a design shown in Figure 11 can be used where a column (153) is shown that has holes (21) that the separations between them are not only vertically, but also horizontally, being able to thus having separations between the holes (21) very small vertically without the risk of overlaps in the holes or very thin walls between holes.

Figure 11 shows. the shape of the latter mode (fork-shaped part being fixed central support) where the column (153) has several vertical lines of holes and the fork has only one hole and is fixed in the hole (21) by the bolt (160), the hole in which it engages It will be the one that corresponds according to the need of the exercise. Figure 12 shows a situation similar to that of Figure 11 with the difference that the central support is connected to the vertical support in another line of vertical holes. In the cases of figures 11 and 12 the central support will rotate using the ^' center of the bolt (160) as the axis of rotation until the ^' end

Opposite of it make contact with the floor.

In Figures 11 and 12 3 vertical rows of holes ^• shown, however this is not a constraint then may be two or more vertical rows of 'holes.

The central support in the mode in which the fork-shaped part is fixed to the central support, this may be a direct part of the central support, or it may also be that the fork-shaped part is not a direct part of the central support it is a separate piece which is coupled to the central support in a way that is fixed (without movement). ^This' can be achieved through a system or fixing mechanism such as two bolts or may also be the case that the shaped piece fork can rotate (to reduce the space saving "device) and is secured in working position by a bolt or a stop (movement limiting structure) -.

The central support is the piece that connects to the vertical support in various ways as explained in this text, this central support has some rails ^• on which the platform moves in its career during the execution of the exercise. There are two rails (left and right) on which the platform rolls and each of them can be composed of more than one piece as we will explain later. The rails are joined at the top of the central support by the bar (31) and at the bottom by the bar (32) as follows: the upper part of the upper left rail is connected to the upper part of the upper rail right and the lower part of the lower left rail is attached to the lower part of the lower right rail as shown in Figure 13. The rails (3) are two, one on each side (left and right) and preferably each will be composed of two- components that are: the top rail and the bottom rail of each side as shown in Figure 13 showing the upper left rail (301), the lower left rail (302), the upper right rail (303) and the lower right rail (304)

In all the modalities in the rails can be folded (to save the device and take up less space) the components of the rail on one side are joined by a connecting element

(33). Figure 13 shows the connecting element (33) in generic form, the particular shape and characteristics of this connecting element (33) will be different for each coupling mode between the top and bottom of each rail.

These particular characteristics for each modality of the connector element (33) will be described later.

In all cases where this connecting element (33) is used for each rail, the two connecting elements (that of the right rail and that of the left rail) are joined by a bar (34) which provides stability to the structure as Figure 13 shows it. The bar (34) will have a particular shape such that it does not interfere with the rope or the platform when executing the exercise. To the bar (31) (which is the upper bar) is to which the part or parts with which the central support is coupled with the vertical support is connected. Figure 13 shows the type of fork-shaped part being a direct part of the central support. To the bar (32) (which is the lower bar) is to which the base bar (135) of the central support is connected. This base bar (135) is the one that rests on the floor and will preferably have a cylindrical or curved shape so that its contact with the floor does not vary as the angle between the central support and the floor varies. The central support can have fixed stops in the upper part of the two rails (left and right) that have the function of limiting the upward stroke of the platform and that can be made of any resistant material (for example steel) and they can have inserts of materials with suitable elastic characteristics (for example rubber) or also the inserts can be springs, and will have the function of damping the shock of the platform with the central support when arriving at the limit of the race.

At the upper end of the central support, the pulleys are fixed through which the rope passes- (8) The pulleys can be fixed to the bar (31) or to an upper bar structure (136) that is fixed or coupled to the bar (31), is shown in figure 14.

The upper structure (136) may have any shape or size as appropriate, Figure 14 'shows only a generic example of this upper structure. The pulleys are fixed on the bars and the pulleys have adequate clamping means that allow it to move and change its orientation; An example of this is described below in what is a typical pulley assembly. The pulley assembly (161) is composed of the pulley (138), the pulley shaft bolt (137), the pulley fastener (139), and one or more links (140) (optional), as shown by the . Figure 15, Figure 15 only shows one link but may be more than one. These links will give the pulley mobility to fit in the direction that is required according to the exercise. To fix the pulley assembly the last component of the pulley assembly is coupled with the link (141) which is fixed to the upper structure.

The arrangement of pulleys' shown in Figure 14 is typical, however, modes of the invention will be presented below in which the number and arrangement of the pulleys will be different.

The rope (8) can be a rope or a cable or elastic element and be made of any of a large number of possible materials such as: plastic materials, metal materials, synthetic materials, natural materials (eg cotton), etc.

This design ^has' with handles at the ends of the rope may be metallic or non - metallic (for example ropes or tapes). The handles will have ergonomic characteristics that will allow you to perform the exercises easily and without causing harm to the person who exercises.

The rope can consist of two sections independent, and in this case one end of each section is attached to the platform and the other end is attached to a handle.

Some types of handles are mentioned in the section where the characteristic of attaching the rope or the handles to a bar is discussed.

The following describes additional elements that the device can count on.

There are exercises in which the rope is not used to pull the platform, instead of this, upper handlebars are used (in the upper part of the central support) to pull the platform with the arms. There are also lower handles (at the bottom of the central support) that are used to push with the arms and thus move the platform.

On other occasions, a foot rest is used and the platform is pushed upwards with the legs.

For another type of exercise, a foot device is used located at the top of the central support or at the top of the vertical support. With the feet resting on the device and with the person's head toward the lower end of the platform, the person can do sit-ups or pull the platform by shrinking the legs.

Devices such as upper and lower handlebars as well as devices for support of lower and upper feet can be removed and / or folded for when the device is folded for storage.

Other modalities of the central support are that it has two rails and that each one of these is constituted by several components and bends, the characteristics of these modalities are described below.

Figure 16 shows an alternative for rails that bend and consists of two bars: the movable or rotating bar (36) and the fixed bar (35) and which constitute the rail on one side of the central support and a connecting element (37 ) which is a channel-shaped piece with a flat bottom, which is fixed, permanently attached to the bar (36). The upper surface that is over which wheel platform bar (36) ^'is in contact with the flat surface • forming the bottom of the connector element (37). This connecting element (37) has walls in which it has holes (one hole per side) through which a bolt (38) can be inserted and that this bolt will be the axis of rotation of the bar (35).

The rod (35) at the end that engages with the connector element (37) has a hole with which it engages with the connector element (37) through the 'bolt (38). The shape of the rod end (35) is such that when the rod (35) is assembled with the connecting element (37) through the bolt, in its unfolded position, the upper surface of the rod (35) (which it is on which the platform rolls) it makes contact with the flat surface that forms the flat bottom of the channel of the connector element (37) making surface-to-surface contact. When this happens, the bars (35) and (36) have their surfaces aligned which are on which the platform rolls, see figure 16. This same assembly allows the bar (35) to rotate at least 180 degrees on the axis in where is the bolt (38) to bend the rails. Figure 17 shows the same assembly as that of Figure 16 but with the rails in bent position. The shape of the end of the bars (35) allows it to rotate to bend the rail without interfering with the bar (36) or with the connecting element (37). Figures 16 and 17 represent one of the two rails

(left or right) on which the platform rolls, the design has another set of bars like the one described in figures 16 and 17 to form the other rail. The platform rolls on the two rails (left and right). Figure 18 shows another alternative in regard to the bending of the rails and consists of two bars (39) and (40) that constitute the rail on one side of the central support and a connecting element (41) which is a piece in Channel shape with flat bottom. This connector element (41) has walls in which they have two holes per side through which they can be

^' Insert two bolts (42) and (43) the bolt (43) will be the axis of rotation of the bar (40) and the bolt (42) is the axis of rotation of the bar (39).

The shape of the connector element (41) and the bars (39) and

(40) is such that when the bars (39) and (40) are unfolded, their upper surfaces (which is on which the platform rolls) make contact with the flat surface that forms the flat bottom of the channel of the connector element ( 41) making surface to surface contact. When the bars (39) and (40) are unfolded, their upper surfaces are aligned. Figure 19 shows the bent rail, this assembly allows the bars (39) and (40) to rotate at least 90 degrees each on its axis to bend the rail. The shape of the ends of the bars (39) and (40) allows them to rotate to bend without interfering with each other or with the connecting element (41). Figure 20 shows another alternative with regard to the bending of the rails and consists of two bars (44) and (45) that constitute the rail on one side of the central support and a connecting element (46) which is a piece in Channel shape with flat bottom. This connecting element (46) has two walls in which they have two holes per wall through which two bolts (47) can be inserted and (48) the bolt (47) will be the axis of rotation of the bar (45) and the bolt (48) is the axis of rotation of the bar (44) .-

The end of the bars (44) and (45) which are coupled to the connecting element (46) have a flat part of their surface and which is perpendicular to the upper surface (on which the platform rolls). When the bars (44) and (45) are in their unfolded position, the aforementioned flat surfaces make contact with each other and support the structure. The shape of the connecting element (46) is such that when the bars (44) and (45) are unfolded, their upper surfaces (which is on which the platform rolls) make contact with the flat surface that forms the bottom of the channel with flat bottom of the connector element (46) making surface-to-surface contact. When the bars (44) and (45) are unfolded, their upper surfaces (on which the platform rolls) are aligned. The connecting element (46) may require an opening, at the bottom that allows the rods (44) and (45) to rotate on its own axis to bend the rail

Figure 21 shows the folded kidney, this assembly allows the bars (44) and (45) to rotate at least 90 degrees each on its axis to bend the rail. The shape of the ends of the bars (44) and (45) allows them to rotate to bend without interfering with each other or with the connecting element (46).

The platform is the component of the device on which the person stands to do the exercise.

The person when exercising is positioned on the platform and pulls the ends of the rope, bringing the platform up the slope of the central support.

The platform has ^" a rectangular shape (long sides parallel to the direction of movement of the platform and short sides perpendicular to the direction of movement of the platform) and is primarily composed of the following elements: a platform base (145) (occupies the entire surface of the platform), a padded cover (146) (on which the person is placed to do the exercise) and four wheels at least located near the corners of the platform.

We will describe the way in which one of the wheels is coupled to the platform, the way in which the other wheels are coupled to the platform will be similar. The platform on its sides (long sides of the rectangle) has external sills (143) and internal sills

(144), see figure 22. The external hearth (143) is located all along the side (thus agreeing to several modalities that will be described later). The inner hearth (144) is parallel to the outer hearth (143) and is also positioned towards the center of the platform. The ^' internal hearth (144) does not have to be all along the platform, it only has to be in the sections where the wheels (147) of the platform are located. Figure 23 clearly shows how the wheels (147) are coupled to the platform. The wheels are arranged between the outer hearth (143) and the inner hearth (144). Crossing these two screeds is a bolt (148) which is the axis of the wheel.

The wheel (147) rotates on the rail (3). Each wheel has a larger diameter section (150), either towards the inner or outer part of the rail. All wheels must have the largest diameter section either on the inner part or on the outside of their respective rail. This section of larger diameter (150) does not rotate on the rail and its function is to prevent the platform from leaving the rail. The larger diameter section can also be on both sides of the wheel.

The platform in its more conventional modality (other modalities will be described later) counts in the part that points to the vertical support with a pulley (151), see figure 24.

Below we will describe some additional innovative features that the design has:

An innovative feature is the arrangement of pulleys. In the designs that currently exist they have an arrangement of pulleys as shown in Figure 25 and consists of having a central pulley (23) on the platform and two pulleys (24) and (25), one on each side at the upper end of the central support This arrangement has the disadvantage that as the platform rises on the central support the force to move the platform is greater as shown in Figures 26 and 27. Figure 26 shows the position of the rope (8) when the platform is in a position lower on the central support (at the beginning of the exercise) and figure 27 shows the position of the rope (8) when the platform is in a position higher on the central support than the position of the platform of the figure 26.

As the platform moves along the central support upwards, the angle formed by the rope (8) changes from angle D for figure 26 to angle E for figure

27 and as can be seen when changing the angle, the direction in which the force is applied also changes, so to pull the same weight a greater force is required when pulling the rope as the angle of the rope is greater. The above is noted in figures 26 and 27 where Ft is the force to move a constant weight and to achieve it the forces Fl and F2 of the figure 26 are of less magnitude than the ^' Fl and F2 forces of Figure 27. The Fl and F2 forces are what. the person who exercises is applied.

The proposal 1 to ensure that the force is constant when pulling the platform, is that the rope (8) is parallel to the movement of the platform, so that the forces Fl and F2 that are applied through the rope (8) also they are parallel to the movement of the platform so it does not form an angle when there is displacement of the platform. See figure 28.

The design of figure 28 consists of placing two additional central pulleys (142) to the lateral pulleys (24) and (25) the central pulleys (142) preferably joined to the central support through which the rope (8) passes and which make the rope (8) is almost parallel to the movement of the platform (in the condition of tension of the rope), these pulleys (142) only change the direction of the force, not the magnitude of it, so that the force is keeps constant along the path of the platform for a constant weight. Figure 28 shows the arrow M indicating the direction of movement of the platform. This arrangement of pulleys is also shown in Figure 29. Due to the above, a more uniform exercise results.

There is the option that the central pulleys are attached to the vertical support; When this happens, the pulleys will be movable to adjust to the different coupling heights of the vertical support with the central support. The central pulleys will be attached to a structure, which is coupled to the vertical support at different heights by means of a bolt.

All pulleys have adequate fastening means that allow them to have movement and change their orientation. Proposal 2 is shown in Figure 30 in which the platform contains three pulleys (26) (27) and (28) instead of A pulley that is common. The other two pulleys (26) and (28) have the function of modifying the shape of the rope (8) when passing through the pulleys. With this new arrangement, the rope sections (8) that leave the platform until reaching the side pulleys (56) and (57) of the central support have a direction almost parallel to the direction M of movement of the platform. Therefore, the force applied to move the platform is practically parallel, in the direction of the movement of the platform (in conditions of tension of the rope), so it is practically constant. The pulleys (56) and (57) are attached to the central support.

Figure 31 shows the same case as Figure 30 but in this case the platform has only two pulleys (29) and (30), these pulleys have the function of modifying the shape of the rope

(8) when passing the pulleys. With this new arrangement, the sections of the rope (8) that leave the platform until reaching the side pulleys (56 and (57) of the central support have a direction almost parallel to the direction of movement of the platform (in conditions of tension of the rope.) Therefore, the force applied to move the platform is practically parallel to the direction M which is the direction of movement of the platform, so it is practically constant, the pulleys (56) and (57) are attached to the central support.

Figures 72 and 73 show other pulley configurations for the platform; Pulleys (171), (172) and (173) are for Figure 72 and Pulleys (176), (177), (178) and (180) are for Figure 73. Figures 72 and 73 show that they can have different paths for the rope (8) and the forces Fl and F2 applied through the rope (8) will be practically constant along the path of the platform provided that the direction of the rope (8) when leaving the platform pulleys, be almost parallel to the direction of movement of the platform (in conditions of rope tension). This direction of the rope (8) is applied from the rope exit of the platform pulleys until reaching the next pulley connected to the central support. The pulleys (56) and (57) of the figure

72 are attached to the central support. The pulleys (56) and (57) of Figure 73 are attached to the central support.

As can be seen from what is shown in the previous figures, the platform will comprise one or more pieces with any location and fixed in any way that will have two main functions: the first function is to connect the platform with the rope so that at the time of exercising the person pulls the The ends of the rope and the platform move, the second function is to shape the path of the rope.

The central support will have an arrangement of pieces or pulleys so that together with the pieces or pulleys of the platform it can be had in the sections of the rope that leave the platform a direction almost parallel to the direction of movement of the platform (in conditions of tension of the rope), so that the force applied when pulling the ends of the rope will be practically constant along the path of the platform.

For this innovative feature the distance that is pulled at each end of the rope is the same as the platform moves

For this innovative feature (constant force during the exercise), there is the possibility that instead of pulleys coupled to the platform, only fixed parts are preferably used with rounded corners through which the direction of the rope changes. This is due to the fact that practically the rope does not run through the pulleys of the platform.

For this innovative feature (constant force during the exercise) in its two proposals it is possible that in practice the pulleys cannot be placed in a position such that the rope is in a position perfectly parallel to the direction of movement of the platform, it can be If there is a slight variation in the direction, this variation in the ^' force along the path would be minimal and practically negligible.

Rope '(8) may be composed of two parts, ^one instead of a single length of rope can ^be' having two sections, each of which is attached at one end to the platform and the other end passes by one or more pulleys until reaching the end in which it is attached to the corresponding handle. The important aspect to consider is that the direction of the ropes leaving the platform (in tension condition) is practically parallel to the direction of movement of the platform whereby the force is constant along the path of the platform . An innovative feature is that because the force with which it is pulled is practically constant when pulling the platform and that the magnitude of this force varies for each position. coupling the central support to the vertical support, the person who exercises can know the force he is doing during the execution of the exercise. The force can be measured by placing an instrument to measure the load such as a tension balance and see what force the person positioned on the platform and the platform cause for each coupling position between the vertical support and the central support.

The points for placing the measuring instrument (example: voltage balance) are the upper middle part of the central support and the middle part of the upper end of the platform.

The advantage of this characteristic is that the exercise ceases to be an exercise of a qualitative type and becomes an exercise of a quantitative type, in which the person who performs the exercise knows the magnitude of the force he exerts when exercising.

Another innovative feature is that the present design has the possibility of changing the position of the center piece or pulley of the platform, the advantage of this feature is that it allows the initial length of the rope to be varied.

We will define the initial length of the rope along the length of the rope from its end (the point of contact with the handle) to the point where it makes contact with the first fixed pulley for each end of the rope for a specific position of the platform.

This mentioned above is especially useful because it adapts the rope for the different types of exercises where it is required to start with different initial length of rope and for cases in which the different people who exercise in the apparatus have different heights and length of limbs so your initial string length requirements are different.

The way in which the initial length of the rope can be varied is due to the fact that in the lower part the platform has two soleras (61) arranged in parallel and separated from each other along the central part of the platform as shown in figure 32. The floorboards have separate holes (62) and the centers of the holes of one hearth are axially aligned with the center of the holes of the other hearth that is to say that they are arranged in such a way that a bolt rigid with slightly lower ^'diameter hole diameter can be inserted through the holes of the two screeds.

Figure 33 shows the typical shape of the mobile central pulley where it has an upper section with two holes (64) with a diameter and separation equal to the holes (62) -. The bottom section is where it is. Find the pulley (50) and the pulley cover (49), the latter prevents the rope from falling off the pulley. The upper part of the pulley is placed between the screeds (61) and is fixed in place by the bolts (65), and this piece can be placed in different positions along the screeds as shown in Figures 34 and 35 By varying the position of the mobile pulley, the initial length of rope is varied. Instead of pulley the piece can have a shape with rounded corners where the rope passes. In figure 33 two holes (64) are shown but in practice they can be two or more holes and also instead of using bolts an equivalent can be used for example a piece in the form of (U), to use the piece in the Figure 33, the holes (62) are separated in an equidistant manner. In the case where the screeds (61) are sufficiently separated, a movable pulley model can be used as shown in figure 71 where the part or pulley

(52) has a section with holes (53) at the same level and at the opposite end to the point where the rope passes. This section with holes is coupled with the holes (62) of the screeds (61) through bolts; Depending on which holes it engages, the initial length of the rope will vary. Instead of pulley the piece can have a shape with rounded corners where the rope passes. In figure 71 two holes (53) are shown but in practice they can be one or more holes, if one is the number of holes of the piece shown in figure 71, will use a single bolt.

To facilitate moving the moving part or pulley located at the bottom of the platform, the platform can be shaped so that its upper surface (on which the person is positioned to perform the exercise) has a mechanism that allows it to function as a door, in such a way that when opening this door the lower structure of the platform where the mobile pulley and the sills (61) are exposed and the position of the piece or mobile pulley can be easily changed from inside of the platform.

The screeds (61) are not necessarily flat as shown in the drawing, they may have some folds in their configuration that allow the piece or mobile pulley to slide in them without falling to the floor. Another innovative feature is that the platform can be modified in such a way that instead of having a continuous surface on which the person is positioned, the surface can be folded all or some parts of it to form a seat. 36 shows the initial position of the surface of the platform, Figure 37 shows a ^'platform where a portion of it is bent to form a seat.

This change of shape in the platform can be achieved because the surface of the platform - can be constituted by two or more sections. Figure 38 shows a part of the platform on whose sides (66) there is a hinge-type mechanism (67) connected to the movable part (162) that can rotate to form the seat.

The sides of the platform that are below the rotating part have a series of grooves or channels (68) arranged symmetrically on both sides of the platform.

These channels (68) have the function embone with the stop piece

(69) and to fix its position, the stop piece (69) is the support of the piece that forms the seat. By varying the position of the piece

(69), the seat angle is adjusted, so that when the piece (69) is brought closer to the axis of rotation the angle is increased and when the part (69) is moved away from the axis of rotation, the angle of the seat is reduced With the rest of the platform. The above what Figures 38, 39 and 40 are shown. This change of angle of the platform seat is to adjust the seat as much as possible to a horizontal position when I varied the angle F.

There may be more than one part of the backrest of the platform that can rotate and change its position as shown in Figures 41 and 42. The type of exercise and the characteristics of the person exercising will determine which part is rotating and the angle Turn of it.

The advantage of this innovative feature when having a seat, for certain types of exercises, the person who exercises can maintain an upright and symmetrical position, which benefits the execution of the exercise and reduces the possibility of injury to the person who exercises.

A variant with respect to the fact that there is a seating shape on the surface of the platform, is that instead of rotating part of the platform, a hairpiece (70) is placed that fits with axes (71). There is a possibility that axes (71) are positioned in several places along the sides of the platform so that the insert is placed in several positions, as shown in Figures 43 and 44. Figures 45, 74 and 75 show the way in which the seat rotates and is fixed at its angle to adapt to the ^" variation of angle G. The hairpiece (70) can have a backrest as shown in Figure 78.

To fix the position of its turning movement, the seat has a bar or hearth (63) on each side, which can have a hinge-type mechanism (74) that allows it to rotate. This solera (63) can be straight or have a certain curvature and has a series of holes (75) along it.

On each of the two sides (77) of the platform is a plate (76), which is fixed to the side of the platform and separated from the surface of the side of the platform by a distance greater than the thickness of the bar or Solera

(63). This plate (76) is attached 'at its ends to the side (77) of the platform by different fasteners such as: rivets, screws or welding. The separation that these fasteners have between them allows the bar or solera (63) to pass between the plate and on the side of the platform.

The plate (76) has one or more holes (79) axially aligned with one or more holes (80) on the side (77) of the platform as shown in Figure 75. To fix the angle of the false seat, it can rotate at its pivot point (71), the bar (63) is passed between the plate (76) and the side (77) of the platform (on both sides of the platform), to fix the position, it is made Pass a bolt (124) through the holes (79) (75) and (80). The angle of the seat will depend on which of the holes (75) of the bar or hearth (63) matches the bolt (124).

An additional innovative feature on the variant with respect to the fact that there is a seat shape on the platform surface is to insert a bar to support the feet while sitting and it consists in that the lower part of the piece that forms the seat has a structure like the one shown in figure _V 46 where the bar (83) (hollow or ^' solid of any profile) is inserted frontally or laterally into structures that have a housing with the profile of the bar (83) according to to what the arrow (81) or the arrow indicates

(82) and it is secured with the bolts (84) or (85) as the case may be and it will be as shown in Figures 47 and 48, so that the person who exercises feels front or side as required.

Figure 49 shows that at the end of the bar (83) an extension (86) is inserted and fixed in position with the bolt (88) (one or more bolts can be). The extension (86) is a bar and has a series of holes (87) along it to vary the position with respect to the bar (83) whereby the distance of the extension end (86) is varied to the seat The extension (86) has at its end (the one that is not inserted) a crossbar (89) that serves to support the feet of the person who is exercising while the person is sitting in the seat.

This feature has the advantage that the person who exercises when sitting and supporting the feet has a very good stability and support for the upper body when exercising. Another innovative feature of this design is that a pulley with variable position (one per side) is installed on the outer sides of the platform, which has the function of changing the direction where the rope is pulled to do the exercise.

In the known technique there are designs that have pulleys on the side of the platform, the advantage offered in the present design is that the pulleys are mobile, that is, they can change position along the side of the platform. The platform has one or more positioning devices (90) placed along the outer sides of the platform as shown in Figure 50. Figure 51 shows in detail how these devices (90) are constituted. The devices are projections (51) preferably with a rectangular hearth shape that are arranged on top of each other in a parallel manner preferably in the direction of movement of the platform, and that are separated from each other and that have one or more holes (91) (Figure 51 shows a single hole). Said projections (51) are arranged ^{'symmetrically} on both outer sides of the platform. The projections (51) can be permanently fixed or removable by any method (riveting, welding, screwing, etc.) to the side of the platform. The way in which the variable position pulley is connected to this device (90) is as follows: Figure 52 shows as a piece called pulley support (92),. embeds in the separation between the pieces (51), this pulley support has one or more holes (a single hole is shown in figure 52) which is matched with the holes (91) and secured with the bolt ( 95). The pulley support has another hole (93) to which the last link of the pulley assembly is coupled. The pulley assembly (161) is composed of the pulley (138), the pulley shaft bolt (137), the pulley fastener (139), and one or more links (140), as shown in Figure 53, Figure 53 only shows one link (140) but may be more than one. These links will give the pulley mobility to fit in the address required according to the exercise.

If these mobile pulleys are not used on the sides of the platform, they are disassembled by removing the bolt (95) and this group of pieces can be slid along the rope and secure this group of pieces to the nearest fixed pulley assembly . The way in which this group of pieces can be secured is by some type of belt or strap of any material or by some mechanical connector.

In case of attaching the group of parts to the nearest fixed pulley assembly, great care must be taken that there is a lot of slack in the clamp, so that the movable pulley does not interfere in the sliding of the rope during the execution of the exercise .

If you have a simple mechanical mechanism to remove the handle and put it back on, you can remove the handle, remove the rope from the movable pulley and reconnect the handle. To prevent the mobile pulley from being connected to the platform, you can remove the bolt (95) and remove the set of parts with the mobile pulley and place these parts where they do not hinder to continue doing the exercise.

The advantage of this innovative feature is that by changing the direction where the rope is pulled to do the exercise, it allows for a greater number of different exercises that can be performed on the device, as well as simplifying the execution of Some of the exercises.

Another innovative feature is that the design has a system of mobile stops for the platform. These stops are to limit both the upward and downward travel of the platform. Figure 54 shows the rail (3) on which the platform slides, along the rail (3) in its lower part there are transverse elements (103) (these transverse elements are protruding in the lower part and lateral faces of the rails). These transverse elements have faces perpendicular to the direction of movement of the platform. These transverse elements (103) are arranged symmetrically on both rails (left and right). These Transverse elements (103) protrude on both sides of each rail as shown in Figure 55 which is a view of the rail (3) from below. These transverse elements (103) are fixed on the rail. Figure 56 shows the movable stops (104) that are preferably shaped pieces of rectangular prism, and that have extensions (105) preferably rectangular in one of the faces, these lateral extensions (105) form two channels. (106) and (107). The channel (107) is taller and slightly wider than the rail, the other channel (106) is preferably the shortest and is slightly wider than the transverse element

(103). The channel (106) can also be in the form of (T) or the like so as to allow the transverse element to be better accommodated in the stop as shown in Figure 76, this type of geometry presents a greater safety for the stop when engaging with the element transversal.

The way in which the stop (104) is coupled with the apparatus is shown in Figure 57 and is as follows: the stop (104) is mounted through the channel (107) on the rail (3) and the other channel ( 106) is mounted on the transverse element (103), such that when the end of the platform (125) makes contact with the stop (104) it can no longer move forward because the elements (105) of the stop are already in contact with the transverse elements (103) that are fixed. In the case where the channel (106) is in the form of (T), the coupling is shown in Figure 77.

The stops must be placed on ^• the two rails (left and right) symmetrically so that when the platform contacts the ^" stop, the contact force is balanced and ^• the platform retains good stability.

The stops (104) can have on the face of contact with the end of the platform (125) an elastic element such as rubber, polymer or even in some cases a spring that will have the function of damping the impact of the platform with the stop, top, maximum as a noun, top as an adverb. The advantage of this feature (mobile stops) is that it allows you to limit the starting and ending point of the movement of the platform so that the platform can be positioned in the best way for the execution of each exercise.

Another innovative feature is that there is the possibility of moving the pulleys coupled to the structure located in the upper part of the central support. Figure 79 shows the pulleys (183) and (184) that can be moved and placed in different positions on the bars of the structure (185). The upper structure (185) corresponds to the structure (136) in another modality.- All. the pulleys have adequate fastening means that allow them to have movement and change their orientation.

The pulleys (183) and (184) are each coupled to a channel-shaped piece (186) and (187) which can be coupled at different points with the structure (185) and secured with the bolts (188) and (189) that cross the pieces (186) and (187) and the bars of the structure, (185), thus fixing the position of the pulleys, see figure 79.

The structure (185) located ^' in the upper part of the central support can have any shape or dimensions that is convenient. It also has several holes (190) through which the pieces (186) and (187) can be coupled with the structure (185). Depending on what is most convenient, the structure (185) can be fixedly attached to the central support or by elements that allow it to be removable such as screws.

The upper structure (209) corresponds to the structure (185) in another embodiment and that is where the pulleys are attached, it is located in the upper part of the central support, it is possible to fold down when the device is folded for storage , see figure 85.

The upper structure (209) has an axis of rotation located below the level of the rails (301) and (302), as shown in Figures 85 and 86. The structure (209) rotates on this axis until it is practically parallel. to the rails as shown in figure 87. To place the structure in working position, it must be turned until it makes contact with the upper part of the central support which acts as a stop (structure limiting movement). And it is held in place by springs or mechanical means. Another innovative feature is to attach a bar to the handles. In the current designs at the ends of the rope there is a handle on each end for ease of attachment when pulling the rope and performing the exercise. The proposal of this design is to attach the handles that the device currently has to the ends of a bar and exercise through pulling or pushing the bar.

In the known technique there are designs in which the possibility of attaching a bar to the rope is contemplated, however the present design contemplates a variety of options for coupling the bar to the components of the apparatus.

In this design three types of typical handles and their respective way of attaching them to the bar are presented.

The first type is shown in Figure 58 and the handle consists primarily of a bent wire that has the following form: it consists of a ring-shaped section

(96) which is the one that connects to the rope (8), then changes to a curved shape (97) to surround the fist of the person holding it and then becomes straight (98) which is the section of where the handle is held.

To attach the handle described above to the ends of the bar (109), the latter has at its ends a hole where the straight end of the handle enters as shown in Figure 59. Figure 60 shows that the ends of the bar (109) also have a groove (99) where part of the handle enters for greater firmness in the coupling. The configuration shown in Figures 59 and 60 applies to both ends of the bar.

Sometimes the straight part of the handle has a cover which increases the diameter and can be fastened better, in these cases the hole at the end of the bar must be large enough to accommodate the part of the handle with the cover, or you can also remove the cover and attach the handle without cover to the bar. Figure 61 shows the second type of handle (110). The handle is a piece that has a triangular shape and that in the upper part is shaped like a central ring (100) that It is where the rope (8) is connected. The sides (101) of the piece are preferably symmetrical and can be curved, the part of the piece that corresponds to the base (102) consists of a round and hollow piece. Figure 62 shows how to connect the bar (60) to the handle (110). The end of the bar (60) in the hollow portion of the handle is introduced, bar (60) has near the ends with an enlargement (59) in diameter serving ^'cap when the handle is inserted (110 ). What is indicated for one end of the bar also applies to the other.

For the type of handles shown in Figures 58 and 61, the corresponding bar with which they are coupled can contain elements such as: springs, or springs etc., which are elements that yield by elastic effect when inserting the handle, and once coupled the handle, these elements hold it in place opposing its exit. The handles can also be held in place by means of a bolt at the ends of the bar, said bolt is removed from the bar to insert the handle and once the handle is inserted, it is placed back through the bar and thus prevent the handle comes out of its place.

The third type of handle is not of the metallic type and is shown in Figure 63, this type of handle is a rope, tape or strap (111). This tape (111) is connected to the bar (58) as shown in Figure 64. Figure 65 shows the end of the bar (58) held by the tape (111) and how the bar can be seen

(58) has at its end two sections of larger diameter on the sides of the handle coupling point, this always makes the handle (111) in the same position on the bar (58) and also prevents the handle will come out. What is indicated for one end of the bar, applies to both ends.

If you have a simple mechanical mechanism to remove the handle and put it back on, you can remove the handle, connect the ends of the rope with the bar at its ends and proceed to perform the exercise, when the exercise is finished , you can disconnect the rope from the bar and reconnect the handles. All the aforementioned bars (58), (60) and (109), will have a sufficient length that allows the bar to be held with both hands and that the handles are properly separated to perform the exercise.

5 There is a case where the bar is very short, and this case applies when the two handles are pulled with one hand, in this case the bar could be short.

The advantage of this characteristic is that for certain types of exercises it is much more convenient to push or pull with both '10 hands a bar instead of holding a handle with each hand and pull or push simultaneously.

Another innovative feature in this design is that there is a system for exercising the legs in a

.exercise consisting of flexing and stretching the legs in shape

15 alternated. The system of exercising the legs is shown in Figure 66.

In figure 66 you can see the pedals (112) 'which are on which the feet are supported.- Each of these pedals is connected by means of a connecting rod (113) to a crankshaft type mechanism 20 and this one to You are connected to a main wheel or disc (114). The movement of the pedals (112) causes the main disc (114) to rotate.

The pedals (112) have the possibility of changing the connection point with the connecting rod, since each pedal has a series of holes (117) to each of which the connecting rod (113) can be connected and fixed by a bolt (126). By varying the position of the connecting rod (113) on the pedals (112), the range of motion of the pedals is varied. As the connecting rod (113) is connected closer to the axis of rotation (116) of the pedals (112), the amplitude 0 will have the pedal stroke and the greater the flexion and extension of the legs for the person exercising. Also by varying the race, the force necessary to move the pedals is varied (the greater the race, the lower the force made by the legs). 5 Therefore, it is necessary that the device has elements to vary the resistance of the main disk (114) to rotate. As a result of the above, it You can vary the resistance on the pedals for two reasons: for the race of the pedals (changing the position of the crank on the pedals) and for varying the resistance to rotation of the main disc

(114), which gives a great variety of options to the person who exercises.

Figure 66 shows that the pedal system is on a base (115). The end of the base (115) that is near the pedals is the one that attaches to the rest of the apparatus. This end has the form of a channel, and it is on this channel where the rest of the apparatus is coupled.

The pedal system can be fixed to the rest of the apparatus through pieces that fit together and fixed through bolts or screws, or some other type of suitable mechanical means.

The person who exercises can recharge on the platform and operate the pedals with his feet or he can also sit down using the mode in which part of the platform becomes a seat and operate the pedals with his feet.

The design has elements to vary the resistance it presents to rotate the main disk (114), thus varying the force applied by the person exercising the pedals (112).

To vary the resistance to rotation of the main disk (114), it can be done by generating the opposing force directly on the main disk (114), as would be the case for Figure 66. Figure 67 shows another way of apply the opposing force to the turn. Figure 67 shows the main disk (114) which is actually a pulley to which the band (118) is coupled, which connects the pulley disk (114) with the smaller diameter pulley (119). The pulley (119) is directly connected to the disk (120) which is on which the opposing force is applied to the rotation.

The advantage of the arrangement shown in Figure 67 is that a small opposing force in the disc (120) causes a greater opposition force in the pulley disk (114).

There are mainly two types of techniques known to vary the resistance of the disk to rotate; one of them is by magnetic force and the other is by friction.

The first technique is by means of magnetic elements, In order for this method to work, the disk must be made of magnetic material, for example steel. By approaching magnetic elements such as magnets, the disc will show an increase in resistance to rotation and as a consequence the force necessary to move the pedals will increase. To remove the magnetic disk can be elements such as magnets, disk present a decrease in resistance to rotate and ^{'consequently} the force to move the pedals will decrease. It is convenient to clarify that the magnets do not make contact with the disc. The second technique is. as a result of elements that cause a frictional force by contact with the disc and that this causes a resistance _ι to rotate the disc and as a consequence a greater force to move the pedals. The frictional force on the disc can exert radial ^'or axially on it. The advantage of this characteristic is that it allows the person to exercise the legs through flexion and extension movements, in a fast or slow way and the resistance of the pedals can vary. With the above it is possible to exercise the cardiovascular system of the person who exercises, as well as other muscle groups such as buttocks and legs.

Another modality regarding vertical support is that it has a column (182), which has one or more projections (191) on opposite sides as shown in Figure 80. The projections (191) are bars (preferably round ) on which the central support is positioned.

Figure 81 shows that the central support has at its upper end (the one that is coupled with the vertical support) with two extensions (192), each of which is coupled to each side of the column (182) of the support vertical. These extensions (192) are coupled on the projections (191) of the vertical support. The shape of the extensions is such that they engage with the projections (191) and allow the lower end of the central support to rest on the floor.

The extensions (192) have the characteristic that they have an ascending angle with respect to the plane formed by the rails in an extended position of the central support. Along these extensions (192) ^'they have in their lower part a form that it allows them to be coupled in several positions with the same projection (191) simply by bringing or - removing the central support to the vertical support and positioning the extensions (192) on the same projection. With the above it is possible to vary the angle (X) that forms the central support with the floor. The angle (X) that forms the central support with the floor can also be varied by changing the projection (191) on which the extensions (192) are positioned as shown in Figures 82, 83 and 84.

Another modality of vertical support is that proposed in Figure 68, which is a support consisting of a column (201), which has one or more vertical rows of holes (202) and also has a hinge type mechanism (203 ) with which it is coupled with a bar structure called back structure (204) through a bolt (205). Figure 69 is a side view of Figure 68. In the column (201) the piece shaped like a fork of the central support is coupled.

The column (201) and the rear structure (204) form a scissor-type mechanism and when the ends of the column (201) and the structure (204) are separated (open scissors) is the position in which the support Vertical can be used and when the ends of the column (201) and the structure (204) are together (closed scissors) is when the vertical support is in a position to be stored occupying a small space, See figure 70. The column ( 201) and the structure (204) have in their lower part crossbars (206) and (207) with which they rest on the floor.

The structure (204) is longer than the column (201) in such a way that by separating the ends and supporting the vertical support on the floor, the column (201) is in an almost vertical position or much less inclined than the structure ( 204).

The column (201) and the structure (204) are connected to articulated bar mechanisms (208) that serve as braces for when the vertical support is open and when the vertical support bends for storage, these articulated bar mechanisms are fold.

Another innovative feature is that the platform It can increase its weight, for which the platform has a bar (211) that crosses it. This bar (211) is arranged perpendicular to the movement of the platform and parallel to the floor. This bar (211) is positioned towards the lower end of the platform and its ends protrude on both sides of the platform as shown in Figure 88..

At the protruding ends, weights can be placed to increase the weight. To place the weights, it is done by inserting the disc-shaped weights (212) at the ends of the bar (211) that protrude from the platform. To prevent the weights from coming out, they are secured by a mechanical device.

The weight gain on the platform must be the same on both sides of it to maintain a good balance. Another modality regarding the vertical support is the one shown in figure 89 which has two pieces that are: the front (213) which is a frame, ^' and the rear (214) which are joined at the top by A hinge-type mechanism, the front piece (213) has a series of horizontal bars at different heights so that the central support is coupled in its embodiment shown in Figure 81.

The front piece (213) and the back piece (214) form a scissor type mechanism and when the ends of the piece (213) and the piece (214) are separated (open scissors) is the position in which the Vertical support can be used and when the ends of the part (213) and the part (214) are together (closed scissors) it is when the vertical support is in a position to be stored occupying a small space.

The part (213) and the part (214) are connected to articulated bar mechanisms (215) that serve as braces for when the vertical support is open and when the vertical support is folded for storage, these articulated bar mechanisms are fold. See figure 90.

The device has an accessory for exercising cardiovascular type, which has the characteristic that is coupled to the device by mechanical means.

The accessory consists of pedals (216) of type bike that are operated by the person who exercises while positioned on the platform, see figure 91.

The axis of the pedals has at least one pulley (217) that connects by means of at least one belt with a second pulley (218). This second pulley (218) is mounted on a shaft (220), to which a disc (219) is connected which is on which the resistance force will be exerted to move the pedals, also to this same axis is connected a crankshaft type mechanism, which is coupled to a connecting rod (221) by a bolt (222).

In Fig. 91, the disc (219) is connected to the shaft (220), but it can also be mounted on the axis of the pedals.

The connecting rod (221) in turn is connected to the sliding element (223), which has a linear movement limited by the geometry of the rail where it moves and ^' this element has a geometry that allows it to be coupled to extensions (224 ), which are connected to the rope (8).

With the above, when the pedals are rotated, the crankshaft-type mechanism that moves the connecting rod (221) and the sliding element (223) is rotated and the latter being connected to the rope (8) causes it to Move the platform with the person.

The ^'extensions (224) and the string (8) pass through a system of pulleys to additional pulley system that is normally used to work with when the apparatus is used in the device apparatus

The bolt (222) can be repositioned in the crankshaft type mechanism to change the stroke of the sliding element (223). It is important that the sliding element (223) is aligned with the center of the pedals so that the forces are balanced on both sides of the element (223).

There are mainly two types of known techniques for varying the resistance of the disk to rotate; one of them is by magnetic force and the other is by friction.

The device has a simple way of disassembly to save and take up little space, it consists of: Separate the vertical support from the central support.

Fold the vertical support according to the corresponding modality (varies the way for each vertical support modality) Separate the rope platform and the central support

Separate or fold additional support and support elements for feet and hands

Bend the rails of the central support and others. _, components according to the modality of the corresponding central support. In this way there are three main elements (vertical support, central support and platform) separately occupying little space and the elements of the device can be stored separately in different places or all in one place.
