Definitions
- the present invention relates to an apparatus for three-dimensional anaerobic exercise capable of attaining stability in three-dimensional motion trajectories necessary for the human body, and more particularly, to an apparatus for three-dimensional anaerobic exercise, which applies a reduction linkage concept, but not a four-rod linkage concept disclosed in Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712, previously filed by the inventor of the present invention, for safe three-dimensional motion trajectories in approach to each of various regions of the human body, thereby increasing durability, reducing manufacturing costs, and realizing motion trajectories of various kinds, which are merits of the three-dimensional exercise.
- the present invention relates to an apparatus for three-dimensional anaerobic exercise, which can provide a new approaching method for overcoming lots of limitations of Korean Patent Applications, filed on May 17, 2002 and May 27, 2002 by the inventor of the present invention, in basic configurations such as a rocking angle range of ball joints, and an angular motion range of a handle, and a form change of a horizontal trajectory of a linkage.
- the three-dimensional exercise of the reduction linkage concept has a limitation in realistic approach, but can be applied to a rehabilitation program for a predetermined movement area of the human body since the handle is idly rotated on a bearing as shown in FIG. 13 .
- the origin of the term “the initial load machine of Japan Tottori-ken” of Japanese Patent resides in the fact that a movement range is applied only to an initial primary section (I) when the movement range is divided into three as shown in FIG. 14 : an initial section (I), a middle section (II), and a final section (III).
- the L-shaped handle where the handle shaft and the end of the handle are directly connected to each other as shown in FIG. 7 realizes convex motion trajectories from the human body as shown in FIGS. 9 a and 9 b, and so, cannot realize concave motion trajectories necessary for the human body.
- the convex trajectories are one of characteristics of the typical angular motion of the handle when the end of the handle is directly connected to the handle shaft. As shown in FIG.
- the L-shaped handle shows a limitation in realizing the three-dimensional motion trajectories of the human body.
- U.S. Pat. Nos. 5,967,954, 5,562,577, 5,997,447, and 5,582,564 recently, a great deal of studies and attempts have been made to develop exercise devices for realizing motion trajectories necessary for the human body and safe and stable angle of the handle.
- the prior art has limitations in realizing a twist angle of 60 to 120 degrees required by the human body due to the rocking angle (40 ⁇ 50 degrees) of a restricted ball joint since the ball joint is mounted in a horizontal direction from an auxiliary linkage.
- the ball joint can secure the angular motion only by axial mounting suitable for the direction of the angular motion.
- a handle side lever for the angular motion is not mounted integrally with the handle, but must be mounted opposite to the handle from a bearing housing.
- a ball joint connection point located at the lower end portion of the auxiliary linkage must be moved to a position lower than a shaft of a handle linkage to obtain a proper angle of the handle.
- the handle linkage since the length of the handle linkage must be shortened or the auxiliary linkage must be enlarged, considering that the human body is 160 ⁇ 19 cm in height and 45 ⁇ 80 cm in arm length, the handle linkage performs lots of angular motions (V, V′) as a basic motion trajectory as the exercise device is enlarged or the handle linkage is shortened, and so, the human body may show rejection symptoms.
- auxiliary linkage is larger than the handle linkage as shown in FIG. 12 a, in a section x, an angular motion distance y of the handle is successively increased, but if the auxiliary linkage is shortened as shown in FIG. 12 b, the angular motion distance y is successively decreased, so that the length of the auxiliary linkage may have an influence on the three-dimensional motion trajectories of the human body and the form of the convex or concave motion trajectories in view of a plane as shown in FIG. 5 .
- the length of the auxiliary linkage must be similar to or shorter than that of the handle linkage to set an even or proportional angular momentum of the handle and to realize stable motion trajectories. If the auxiliary linkage is longer than the handle linkage, as the angular motion of the handle is rapidly increased and a movement range (a) is varied according to a figure of the human body, it is difficult to provide proper motion trajectories.
- the auxiliary linkage and the handle linkage must not be influenced by any factors excepting a distance (d) between the handle linkage and the auxiliary linkage.
- a handle side lever must closely approach the auxiliary linkage in the case where a cross joint is used, which is one of components of the present invention. Otherwise, since the auxiliary linkage must be longer and the position of the lower side lever must be lowered, the lower lever of the cross joint has a complicated structure and there are lots of restrictions in applying angular motion displacement by section.
- the reduction linkage needs several basic elements for realizing the safe three-dimensional motion trajectories of the handle like the four-rod linkage.
- an angle of the handle when the handle forms predetermined motion trajectories while carrying out the angular motion, an angle of the handle must be made perpendicularly to the power direction of the human body or according to demands of the human body.
- the apparatus for three-dimensional exercise must resiliently apply not a simply circular motion trajectory but concave or convex trajectories of the handle for a correct exercise to the target muscle because the present invention is provided not for a simple joint movement but a multi-joint movement of the upper part or the lower part of the human body.
- first and second handle frames must be connected to the handle shaft and the handle at predetermined angles. That is, the apparatus can induce safe and compatible motion trajectories in various applications if the handle is not directly connected to the handle shaft.
- the present invention can overcome problems of overload due to a single motion trajectory of the conventional two-dimensional exercise apparatus and achieve an effective muscular growth by mounting a plurality of handles to implement various motion trajectories.
- the handle linkage must be mounted in the form of a trapezoid, and at this time, angles ⁇ and ⁇ ′ have the greatest effect in that the handle shaft and the first and second handle frames are fixed with each other at an angle ⁇ as shown in FIG. 4 .
- the handle is set in a perpendicular direction to a movement direction at a movement start point S as shown in FIG. 3 , and a twist amount is about 60 ⁇ 120 degrees.
- the angles ⁇ and ⁇ and ⁇ ′ are offset at a movement end point f as shown in FIG. 4 , so that the movement is finished at right angles to the movement direction or at an angle necessary for the human body. Therefore, as means for securing a safe angle similar to the angle of the handle formed between the movement start point and the movement end point of the four-rod linkage, mounting means forming the angle ⁇ with the handle shaft must be provided.
- the handle is not directly connected to the handle shaft, but is mounted in consideration of characteristics of the angular motion thereof in view of a plane, namely, successive increase and decrease of the angular motion.
- the greatest merit of the three-dimensional exercise is to apply shock to muscle of the human body along various motion trajectories in various ways.
- means for mounting two or more handles and fixing means for a proper shape of the handle, i.e., the second handle frame, must be provided.
- the auxiliary linkage As shown in FIGS. 7, 11 and 12 , as a connection part of the auxiliary linkage is located lower than the handle linkage, the auxiliary linkage must be directly connected to the handle side lever to reduce the absolute length and the width of the linkage. At this time, as shown in FIGS. 2 and 6 , ball joints of the auxiliary linkage are mounted according to the movement directions due to a limitation of a rocking angle of the ball joints.
- a side lever which is directly fixed to the handle shaft, is required.
- the side lever is located at a predetermined position of the handle frame, there may occur interference between the rocking angles of the ball joints as the handle frame is mounted on the handle shaft at a predetermined angle.
- the handle side lever is located on the handle frame, it is difficult to secure a point for a proper angular motion. Therefore, when the side lever is directly fixed to the handle shaft in a direction of the handle frame from a bearing housing, a safe three-dimensional movement of the handle can be induced.
- the second handle frame can attain safety of the handle, which is provided by the four-rod linkage, as being fixed to the handle shaft at the angle ⁇ . Since a side of the handle is not directly connected to the handle shaft, as shown in FIG. 5 , the first handle frame is required as the means using the successive increase and decrease of the angular motion of the handle for the convex or concave motion trajectories necessary for the human body in view of the plane.
- the second handle frame for mounting two or more handles and for providing the shape of proper motion trajectory is connected to the first handle frame at the angle ⁇ .
- the first and second handle frames must be fixed only to the handle shaft when the handle linkage performs the angular motion at the angles ⁇ and ⁇ ′ for an independent trapezoidal biaxial movement.
- the handle shaft must be also fixed to the upper end of the handle linkage at angles ⁇ and ⁇ ′ as shown in FIG. 1 .
- the bearing box must be fixed to the upper end of the handle linkage at the angle ⁇ or ⁇ ′.
- bearings must be arranged at a proper distance from the handle shaft because direct arrangement of the bearing onto the handle linkage may reduce durability or increase volume of the handle linkage. So, the bearing box is required to provide durability of the handle linkage and a proper angle setting of the handle shaft for forming motion trajectories necessary for the human body.
- the present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus for three-dimensional anaerobic exercise, which is another approach of apparatuses for three-dimensional exercise using four-rod linkage (Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712 previously filed by the inventor of the present invention), and which can apply safe and efficient motion trajectories realized by the four-rod linkage to a reduction linkage concept.
- the four-rod linkage for realizing the three-dimensional motion trajectories has an advantage in that an angle of a handle can be maintained uniformly in a movement direction of the human body as an angular motion of the four-rod linkage is not influenced by rotation of the handle.
- the four-rod linkage is not good as having complicated structure and form, a heavy volume, and expensive manufacturing costs.
- the reduction linkage concept proposed as an alternative measure of the four-rod linkage may impose a heavy burden on an exerciser's wrists and forearms as the angular motion of the handle linkage has an influence on the angle of the handle.
- the upper and lower parts of the human body form not parallel motion trajectory but trapezoidal motion trajectories.
- the trapezoidal motion trajectories must be concave or convex motion trajectories when they are seen in view of a plane from the human body. Therefore, the apparatus must form concave or convex motion trajectories to exactly approach target muscle, and realize smooth and safe motion trajectories of the exerciser's shoulders, arms and wrists.
- a first handle frame is required for avoiding a direct connection between a handle shaft and a side of the handle and for setting the handle at a proper position, and a second frame is also required for forming a predetermined angle.
- the upper bearing box of the handle linkage is also maintained at a predetermined angle under the influence of the angle of the handle linkage.
- the angle between the handle shaft and the handle frame is the most influenced by the axially fixed angle of the handle linkage.
- a distance of the first handle frame and an angle between the first handle frame and the second handle frame are influenced by the axially fixed angle of the handle linkage.
- the components must be mounted kinetically and dynamically, and a number of handles must be mounted on the second handle frame.
- a handle side lever is fixed to a side of the handle centering a bearing box, and separated from the handle frame. The reason is that there may occur interference within a range of a rocking angle of ball joints of the lever since the first and second handle frames may be connected to the handle shaft at a specific angle, and the lever may not be located on the handle frame.
- gearing means and a damper in stead of an auxiliary linkage can be utilized to enlarge the angular motion range of the handle.
- a cross joint mounted on the lower shaft can realize wide three-dimensional motion trajectories, and has a guide linkage for freedom and specified twist structure.
- the combination between the cross joint and the guide linkage can realize motion trajectories, which were not realized by the conventional reduction trajectories.
- the apparatus for three-dimensional anaerobic exercise according to the present invention can provide three-dimensional motion trajectories suitable for the human body and allow the human body to do more improved exercise.

- the present invention provides an apparatus for three-dimensional anaerobic exercise, which can overcome restrictions of a conventional reduction linkage in applying three-dimensional exercise by providing an angular motion of a handle suitable for movement directions of the human body as in three-dimensional motion trajectories of four-rod linkages of Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712, which were previously filed by the inventor of the present invention, and realizing stable motion trajectories, thereby allowing the human body to carry out three-dimensional exercise more safely and effectively.
- FIG. 1 shows an apparatus for breast exercise of the upper part of the human body according to a preferred embodiment of the present invention.
- the three-dimensional anaerobic exercise apparatus 1 includes an I-shaped base frame 2 and a tower 3 .
- a seat 4 is mounted on the base frame 2 .
- Handle linkages 5 are inclinedly mounted at right and left sides of the base frame 2 via bearings 6 in such a manner as to form an angle ⁇ in front of the seat 4 , so that the handle linkages 5 can perform an angular motion in back and forth directions.
- a bearing box is mounted on the front end of the handle linkage 5 , and first and second handle frames 8 and 9 are mounted in such a manner as to be rotated by a handle shaft 10 .
- the first handle frame 8 is connected to the handle shaft 10
- the second handle frame 9 is connected to the first handle frame 8 at an angle ⁇ .
- a side lever 11 of the handle is fixed between the first handle frame 8 and the bearing box 7 at a predetermined setting angle (which can be adjusted according to moving parts of the human body) formed with the first handle frame 8 in directions of the first and second handle frames 8 and 9 from the bearing box 7 .
- auxiliary linkage 12 is connected to the handle side lever 11 via a ball joint 13 , and a ball joint 13 a is mounted on the lower end portion of the auxiliary linkage 12 in such a manner as to form a distance d from a fixed lever 14 fixed to the lower end of the front side of the base frame 2 .
- auxiliary linkage ( 12 ) connected at an upper end to the handle side lever ( 11 ) via a ball joint ( 13 ) and mounted at lower end on a fixed lever ( 14 ) fixed to the lower end of the front side of the base frame ( 2 ) via a ball joint ( 13 a ) to form a distance (d).
- the handle shaft 10 performs a circular motion, so that the handle 15 mounted on the first and second handle frames 8 and 9 provides a three-dimensional motion trajectory as shown in FIGS. 3 and 4 to allow the exerciser to do three-dimensional exercise.
- the handle linkage 5 is axially mounted on the base frame 2 at the angle ⁇ or ⁇ ′ for trapezoidal and angular motion
- the auxiliary linkage 12 is connected to the fixed lever 14 of the base frame 2 via the ball joint 13 a at the predetermined distance d from the front side or the rear side of the lower portion of the handle linkage 5 .
- the ball joint 13 a is axially mounted in the same direction as the angular motion of the handle linkage 5 , namely, in a direction that the ball joint 13 a located at the lower portion of the auxiliary linkage 12 is perpendicular to the ball joint 13 located at the upper portion of the auxiliary linkage 12 .
- the bearing box 7 is fixed on the upper end of the handle linkage 5 .
- the handle shaft 10 is axially mounted to the bearing box 7 , and the first handle frame 8 is fixed to an end of the handle shaft 10 in such a manner that an end of the handle 15 is not directly connected to the handle shaft 10 .
- the second handle frame 9 is connected to the handle shaft 10 at the angle ⁇ in such a manner as to adjust an angle of the handle 15 or to mount two or more handles 15 .
- the handle side lever 11 is fixed between the bearing box 7 and the first handle frame 8 in such a manner as to maintain a predetermined angle with respect to the first handle frame 8 .
- the handle side lever 11 is connected to the auxiliary linkage 12 via the ball joint 13 , and the ball joint 13 performs a smooth angular motion similar to an angular motion of the handle shaft 10 .
- the angle ⁇ and ⁇ ′ of the handle linkage 5 is to obtain a trapezoidal structure for multi-joint exercise of the human body, and to induce organic composition with other components.
- the handle linkage 5 is axially fixed at the angle ⁇ and ⁇ ′ and performs the angular motion at angles r and r′, for the angular motion of the handle suitable for the human body, an angle range of r+r′ does not exceed 65 degrees and a motion trajectory a of the upper part of the human body does not exceed 65 cm. Therefore, the length b of the handle linkage 5 is at least 60 cm or more.
- the angle r has an influence on the angle ⁇ formed between the handle shaft 10 and the second handle frame 9 when the handle is located at a side of the human body.
- the angle ⁇ is influenced by the angle ⁇ when the handle 15 is located in front of the human body.
- the reduction linkage can realize safely three-dimensional motion trajectories in view of the plane and side.
- the angle ⁇ is required for offset of the angle r
- the angle ⁇ is required for offset of the angle ⁇
- the successive increase and decrease of the angular motion of the handle 15 is used.
- the motion trajectories formed in view of the plane are the concave or convex motion trajectories from the human body according to the position of the start point S as shown in FIG. 5 .
- the first handle frame 8 for connecting the handle shaft 10 and the second handle frame 9 at the angle ⁇ must be provided for constructing the handle 15 corresponding to portions relative to the start point S and the end point f, and the first handle frame 8 must be fixed to the handle shaft 10 for the safe motion trajectories.
- the apparatus requires means for mounting two or more handles 15 for the safe motion trajectories, differently from a two-dimensional apparatus, which simply changes only the form of the handle.
- a first handle 15 a starts the movement at a range wider than a second handle 15 b and has an angular motion of 60 ⁇ 120 degrees, but finishes the movement at a range narrower than the second handle 15 b. So, the first handle 15 a can increase approach of the target muscle and reduce approach of other muscle in comparison with the second handle 15 b, so that the human body can do exercise in various motion trajectories using one apparatus.
- the first handle frame 8 is provided for mounting of two or more handles 15
- the second handle frame 9 is connected to the first handle frame 8 at the angle ⁇ for forming the angle ⁇ of the handle 15 .
- the ball joint 13 a mounted on the lower end portion of the auxiliary linkage 12 is axially mounted similar to the angular motion direction of the handle linkage 5
- the ball joint 13 mounted on the upper end portion of the auxiliary linkage 12 is also axially mounted similar to the angular motion direction of the handle 15 , so that the ball joints 13 and 13 a having the restricted rocking angle (40 ⁇ 50 degrees) to the movement direction can absorb the angular motions of the handle linkage 5 and the handle 15 when the handle linkage 5 and the handle 15 perform wide angular motions.
- the shaft of the handle 15 and the shaft of the handle linkage 5 are operated in a cross way to each other, and the ball joints 13 and 13 a are operated in a cross way to each other to absorb the angular motion of the handle 15 and the handle linkage 5 , and so, the angular motion range of the handle necessary to the upper part of the human body must be set from 60 degrees to 120 degrees.
- the length of the handle linkage 5 and the length of the auxiliary linkage 12 are similar to each other or the same.
- the ball joint 13 located at the upper end portion of the auxiliary linkage 12 is mounted in such a manner that the handle side lever 11 is fixed to the handle shaft 10 in the direction of the handle 15 from the bearing box 7 .
- the angular motion of the handle 15 is increased or decreased. If the auxiliary linkage 12 is enlarged as shown in FIG. 11 , it is difficult to obtain the stable angular motion of the handle 15 .
- the bearing box 7 is fixed to the front end of the handle linkage 5 at the angle ⁇ or ⁇ ′′, and at this time, the handle shaft 10 is axially fixed at the angle ⁇ or ⁇ ′′.
- the angle of the bearing box 7 fixed to the handle linkage 5 can be controlled to ⁇ or ⁇ ′′.
- the angle of the handle shaft 10 is controlled to ⁇ for approach to the human body, and if the angles ⁇ and ⁇ do not correspond to each other, the angle of the handle shaft 10 is controlled to ⁇ ′ for obtaining the motion trajectories necessary for the human body.
- a damper 16 is mounted in place of the auxiliary linkage 12 to increase the angular momentum of the handle 15 and resistance of the exerciser within the restricted section.
- An adjustable screwing part 17 which uses a male and female screwing method, is used so as to control the angular motion range of the handle 15 .
- FIGS. 15 a and 15 b the angular motion more than 180 degrees is impossible, but as shown in FIGS. 16 a and 16 b, the upper and lower bearing boxes 7 are in close contact with each other, and the spur gears 19 and 20 , which are axially fixed to the handle shaft 10 and the side lever shaft 18 in respective, are connected to the upper and lower bearing boxes 7 respectively, so that the angular motion can be increased by the gear ratio.
- the handle shaft 10 and the side lever shaft 18 must be axially mounted in parallel with each other, and if the handle shaft 10 and the side lever shaft 18 have the same trajectory in, the basic three-dimensional motion trajectories, as shown in FIGS. 16 a and 16 b, the fixed lever 14 of the base frame 2 is located in the opposite direction to the shafts.
- FIGS. 17 a and 17 b show an example where the cross joint 21 is applied for allowing the handle linkage 5 to perform both a back and forth movement and a lateral movement.
- a shaft 21 a of a side of the cross joint 21 is axially mounted on the bearing 6
- a shaft 21 b of the other side is axially mounted to the lower end portion of the handle linkage 5 .
- connection lever 22 is axially fixed to an end portion of the front side of the shaft 21 a, and the other end portion of the shaft 21 a is connected to the lower end portion of the auxiliary linkage 12 via the ball joint 13 a. At this time, the connection lever 22 is in an L shape for absorbing the rocking angle of the ball joint 13 a.
- FIG. 18 shows an example where the spur gears 19 and 20 axially mounted to the bearing boxes 7 of FIGS. 16 a and 16 b and the cross joint 21 of FIGS. 17 a and 17 b are combined with each other.
- fixing pieces 23 and 24 are mounted on the handle linkage 5 and the base frame 2 in the state of FIGS. 17 a and 17 b, and another auxiliary linkage 27 is mounted between the fixing pieces 23 and 24 via ball joints 25 and 26 .
- the auxiliary linkage 27 is to induce the three-dimensional motion trajectory of the handle linkage 5 using the characteristics of the cross joint 21 .
- the trajectory of the handle 15 can induce the trajectory as shown in FIG. 21 b according to the position of the fixing pieces 24 shown in FIG. 21 a.
- the conventional two-dimensional anaerobic exercise apparatus cannot provide a safe motion trajectory necessary for the human body as using single motion trajectory and single resistance, but the three-dimensional anaerobic exercise apparatus according to the present invention can safely apply resistance to the human body by using means such as a cam.
- the three-dimensional anaerobic exercise apparatus can completely control the angular motion of joints of the human body, and so, can control various patterns, such as successive increase and decrease of resistance as providing the safe motion trajectories.
- the present invention can overcome the restrictions and overload problem of the two-dimensional anaerobic exercise apparatus as having two or more handles 15 a and 15 b. That is, the present invention is very effective to muscle growth by applying various impacts to the muscles as providing a safe joint structure at low load.
- the four-rod linkage concept proposed in the application previously filed by the inventor of the present invention secures the safe motion trajectories, but has several problems in that a manufacturing process of the apparatus is very complicated and manufacturing costs are too expensive. As a result of studies of the four-rod linkage, restrictions of reduction can be overcome by approach of the reduced-rod linkage concept. So, the reduced-rod linkage concept can be commercially used since the manufacturing process is simple and the manufacturing costs are inexpensive even though the reduced-rod linkage concept requires various data for motion trajectories corresponding to those formed by the human body.

Abstract

Description
- The present invention relates to an apparatus for three-dimensional anaerobic exercise capable of attaining stability in three-dimensional motion trajectories necessary for the human body, and more particularly, to an apparatus for three-dimensional anaerobic exercise, which applies a reduction linkage concept, but not a four-rod linkage concept disclosed in Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712, previously filed by the inventor of the present invention, for safe three-dimensional motion trajectories in approach to each of various regions of the human body, thereby increasing durability, reducing manufacturing costs, and realizing motion trajectories of various kinds, which are merits of the three-dimensional exercise.
- In addition, the present invention relates to an apparatus for three-dimensional anaerobic exercise, which can provide a new approaching method for overcoming lots of limitations of Korean Patent Applications, filed on May 17, 2002 and May 27, 2002 by the inventor of the present invention, in basic configurations such as a rocking angle range of ball joints, and an angular motion range of a handle, and a form change of a horizontal trajectory of a linkage.
- As shown in FIGS. 7, 9a and 9b of U.S. Pat. No. 5,769,757, exercise using the reduction linkage concept imposes burden on an exerciser's wrists, forearms and shoulders and involves a danger of injury when an angular motion of the handle is simply applied to the human body since an angle of the handle is subject to the angular motion of a reduction linkage. As a result, the exercise using the reduction linkage concept cannot attain safety and variety, which are characteristics of the three-dimensional motion trajectory.
- Disadvantages of the exercise using the reduction linkage concept will be described in more detail as follows. Since a handle shaft and the lower end of the handle are connected directly with each other and rectangular in an “L” shape, the angle of the handle is influenced by the angular motion of a handle linkage. So, as shown in FIG. 9b, angles g and g′ are formed at a start point and an end point of the motion, and thereby, the handle is not rectangular to the movement direction of the human body as shown in FIGS. 8a and 8b of the application previously filed by the inventor of the present invention, and in drawings of U.S. Pat. Nos. 5,997,447, 5,989,165 and 6,071,216.
- Therefore, it is difficult that the prior arts provide a safely three-dimensional exercise as imposing burden on the exerciser's wrists, forearms and shoulders. The reason is that movement of the third linkage of the four-rod linkage is not greatly influenced by the angular motion of the first and second linkages, but the angular motion in the reduction linkage concept is transferred to the angle of the handle as it is.
- In more detail, the three-dimensional exercise of the reduction linkage concept has a limitation in realistic approach, but can be applied to a rehabilitation program for a predetermined movement area of the human body since the handle is idly rotated on a bearing as shown in
FIG. 13 . - The origin of the term “the initial load machine of Japan Tottori-ken” of Japanese Patent (shown in
FIG. 13 ) resides in the fact that a movement range is applied only to an initial primary section (I) when the movement range is divided into three as shown inFIG. 14 : an initial section (I), a middle section (II), and a final section (III). - In the exercise using the reduction linkage concept, in view of the structure of the handle without regard to characteristics of the angular motion of the linkage, the primary load machine of Japanese Patent, which provides an idle rotation, is realistic rather than U.S. Pat. No. 5,769,757 and can provide a safe exercise in spite of the movement within a restricted section.
- The L-shaped handle where the handle shaft and the end of the handle are directly connected to each other as shown in
FIG. 7 realizes convex motion trajectories from the human body as shown inFIGS. 9 a and 9 b, and so, cannot realize concave motion trajectories necessary for the human body. The convex trajectories are one of characteristics of the typical angular motion of the handle when the end of the handle is directly connected to the handle shaft. As shown inFIG. 4 , as a side of the handle must be directly connected to the handle shaft to obtain the concave trajectories, which are most of the three-dimensional motion trajectories of the human body, the L-shaped handle shows a limitation in realizing the three-dimensional motion trajectories of the human body. As disclosed in U.S. Pat. Nos. 5,967,954, 5,562,577, 5,997,447, and 5,582,564, recently, a great deal of studies and attempts have been made to develop exercise devices for realizing motion trajectories necessary for the human body and safe and stable angle of the handle. - As shown in
FIG. 10 , the prior art has limitations in realizing a twist angle of 60 to 120 degrees required by the human body due to the rocking angle (40˜50 degrees) of a restricted ball joint since the ball joint is mounted in a horizontal direction from an auxiliary linkage. - That is, as shown in
FIGS. 2 and 6 , as the ball joint has a restricted rocking angle (40˜50 degrees) in a vertical direction where a circular motion is carried out, the ball joint can secure the angular motion only by axial mounting suitable for the direction of the angular motion. - Furthermore, as shown in
FIG. 7 , a handle side lever for the angular motion is not mounted integrally with the handle, but must be mounted opposite to the handle from a bearing housing. - As shown in
FIG. 11 , if the handle side lever is mounted opposite to a handle frame from a bearing box, a ball joint connection point located at the lower end portion of the auxiliary linkage must be moved to a position lower than a shaft of a handle linkage to obtain a proper angle of the handle. - In this case, since the length of the handle linkage must be shortened or the auxiliary linkage must be enlarged, considering that the human body is 160˜19 cm in height and 45˜80 cm in arm length, the handle linkage performs lots of angular motions (V, V′) as a basic motion trajectory as the exercise device is enlarged or the handle linkage is shortened, and so, the human body may show rejection symptoms.
- Particularly, if the auxiliary linkage is larger than the handle linkage as shown in
FIG. 12 a, in a section x, an angular motion distance y of the handle is successively increased, but if the auxiliary linkage is shortened as shown inFIG. 12 b, the angular motion distance y is successively decreased, so that the length of the auxiliary linkage may have an influence on the three-dimensional motion trajectories of the human body and the form of the convex or concave motion trajectories in view of a plane as shown inFIG. 5 . - Therefore, the length of the auxiliary linkage must be similar to or shorter than that of the handle linkage to set an even or proportional angular momentum of the handle and to realize stable motion trajectories. If the auxiliary linkage is longer than the handle linkage, as the angular motion of the handle is rapidly increased and a movement range (a) is varied according to a figure of the human body, it is difficult to provide proper motion trajectories. The auxiliary linkage and the handle linkage must not be influenced by any factors excepting a distance (d) between the handle linkage and the auxiliary linkage.
- As shown in FIGS. 17 to 21, a handle side lever must closely approach the auxiliary linkage in the case where a cross joint is used, which is one of components of the present invention. Otherwise, since the auxiliary linkage must be longer and the position of the lower side lever must be lowered, the lower lever of the cross joint has a complicated structure and there are lots of restrictions in applying angular motion displacement by section.
- Moreover, the realization of the motion trajectories for three-dimensional exercise of the prior art have no efficiency because there is no device for various motion trajectories, which are the most greatest merits of the three-dimensional exercise, such as a handle frame A and a handle frame B, which will be described in the present invention later, and there is no means for axially fixing the handle shaft at a proper angle.
- That is, U.S. Pat. No. 5,769,757 is nothing but a simply mechanical approach regardless of the tree-dimensional movement of the human body.
- The reduction linkage needs several basic elements for realizing the safe three-dimensional motion trajectories of the handle like the four-rod linkage.
- First, as shown in
FIGS. 3 and 4 , when the handle forms predetermined motion trajectories while carrying out the angular motion, an angle of the handle must be made perpendicularly to the power direction of the human body or according to demands of the human body. - Second, for improved three-dimensional exercise of target muscle of the upper part or the lower part of the human body, as shown in
FIG. 2 , since a basic motion trajectory for two arms movement must be not horizontal but trapezoidal, the other end of the handle linkage with an angle α or α′ must perform a trapezoidal movement in view of a plane. - Third, the apparatus for three-dimensional exercise must resiliently apply not a simply circular motion trajectory but concave or convex trajectories of the handle for a correct exercise to the target muscle because the present invention is provided not for a simple joint movement but a multi-joint movement of the upper part or the lower part of the human body.
- Therefore, the end of the handle must be not directly connected to the handle shaft, but first and second handle frames must be connected to the handle shaft and the handle at predetermined angles. That is, the apparatus can induce safe and compatible motion trajectories in various applications if the handle is not directly connected to the handle shaft.
- The present invention can overcome problems of overload due to a single motion trajectory of the conventional two-dimensional exercise apparatus and achieve an effective muscular growth by mounting a plurality of handles to implement various motion trajectories.
- To solve the problems of the prior art, a basic setting of the reduction linkage concept will be described hereinafter.
- To set the handle safely, as shown in
FIG. 2 , the handle linkage must be mounted in the form of a trapezoid, and at this time, angles α and α′ have the greatest effect in that the handle shaft and the first and second handle frames are fixed with each other at an angle Θ as shown inFIG. 4 . - Therefore, the handle is set in a perpendicular direction to a movement direction at a movement start point S as shown in
FIG. 3 , and a twist amount is about 60˜120 degrees. The angles Θ and α and α′ are offset at a movement end point f as shown inFIG. 4 , so that the movement is finished at right angles to the movement direction or at an angle necessary for the human body. Therefore, as means for securing a safe angle similar to the angle of the handle formed between the movement start point and the movement end point of the four-rod linkage, mounting means forming the angle Θ with the handle shaft must be provided. - Furthermore, as shown in
FIG. 5 , to induce concave or convex motion trajectories or various three-dimensional motion trajectories necessary for the human body, the handle is not directly connected to the handle shaft, but is mounted in consideration of characteristics of the angular motion thereof in view of a plane, namely, successive increase and decrease of the angular motion. - Therefore, means for preventing the direct connection of the handle to the handle shaft, i.e., the first handle frame must be provided.
- The greatest merit of the three-dimensional exercise is to apply shock to muscle of the human body along various motion trajectories in various ways. For this, means for mounting two or more handles and fixing means for a proper shape of the handle, i.e., the second handle frame, must be provided.
- As shown in
FIGS. 7, 11 and 12, as a connection part of the auxiliary linkage is located lower than the handle linkage, the auxiliary linkage must be directly connected to the handle side lever to reduce the absolute length and the width of the linkage. At this time, as shown inFIGS. 2 and 6 , ball joints of the auxiliary linkage are mounted according to the movement directions due to a limitation of a rocking angle of the ball joints. - A side lever, which is directly fixed to the handle shaft, is required. As described in the application, which was previously filed on May 27, 2002 by the inventor of the present invention, if the side lever is located at a predetermined position of the handle frame, there may occur interference between the rocking angles of the ball joints as the handle frame is mounted on the handle shaft at a predetermined angle. Particularly, if the handle side lever is located on the handle frame, it is difficult to secure a point for a proper angular motion. Therefore, when the side lever is directly fixed to the handle shaft in a direction of the handle frame from a bearing housing, a safe three-dimensional movement of the handle can be induced.
- The second handle frame can attain safety of the handle, which is provided by the four-rod linkage, as being fixed to the handle shaft at the angle Θ. Since a side of the handle is not directly connected to the handle shaft, as shown in
FIG. 5 , the first handle frame is required as the means using the successive increase and decrease of the angular motion of the handle for the convex or concave motion trajectories necessary for the human body in view of the plane. - Particularly, the second handle frame for mounting two or more handles and for providing the shape of proper motion trajectory is connected to the first handle frame at the angle Θ.
- The first and second handle frames must be fixed only to the handle shaft when the handle linkage performs the angular motion at the angles α and α′ for an independent trapezoidal biaxial movement. At this time, the handle shaft must be also fixed to the upper end of the handle linkage at angles β and β′ as shown in
FIG. 1 . - For this, the bearing box must be fixed to the upper end of the handle linkage at the angle β or β′. Particularly, to increase durability of a weight training apparatus of heavy load, bearings must be arranged at a proper distance from the handle shaft because direct arrangement of the bearing onto the handle linkage may reduce durability or increase volume of the handle linkage. So, the bearing box is required to provide durability of the handle linkage and a proper angle setting of the handle shaft for forming motion trajectories necessary for the human body.
- Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus for three-dimensional anaerobic exercise, which is another approach of apparatuses for three-dimensional exercise using four-rod linkage (Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712 previously filed by the inventor of the present invention), and which can apply safe and efficient motion trajectories realized by the four-rod linkage to a reduction linkage concept.
- The four-rod linkage for realizing the three-dimensional motion trajectories has an advantage in that an angle of a handle can be maintained uniformly in a movement direction of the human body as an angular motion of the four-rod linkage is not influenced by rotation of the handle. However, the four-rod linkage is not good as having complicated structure and form, a heavy volume, and expensive manufacturing costs.
- The reduction linkage concept proposed as an alternative measure of the four-rod linkage may impose a heavy burden on an exerciser's wrists and forearms as the angular motion of the handle linkage has an influence on the angle of the handle.
- Therefore, in the reduction linkage concept, to secure safety realized by the four-rod linkage, it is required to analyze characteristics of movement of the upper part of the human body and apply kinematics in connection with angle displacement of the handle during the angular motion.
- When the exerciser does exercise, the upper and lower parts of the human body form not parallel motion trajectory but trapezoidal motion trajectories. At this time, strictly speaking, the trapezoidal motion trajectories must be concave or convex motion trajectories when they are seen in view of a plane from the human body. Therefore, the apparatus must form concave or convex motion trajectories to exactly approach target muscle, and realize smooth and safe motion trajectories of the exerciser's shoulders, arms and wrists.
- To this end, a first handle frame is required for avoiding a direct connection between a handle shaft and a side of the handle and for setting the handle at a proper position, and a second frame is also required for forming a predetermined angle.
- When a handle linkage is axially fixed at a predetermined angle, the upper bearing box of the handle linkage is also maintained at a predetermined angle under the influence of the angle of the handle linkage. Particularly, the angle between the handle shaft and the handle frame is the most influenced by the axially fixed angle of the handle linkage.
- A distance of the first handle frame and an angle between the first handle frame and the second handle frame are influenced by the axially fixed angle of the handle linkage.
- As described above, the components must be mounted kinetically and dynamically, and a number of handles must be mounted on the second handle frame.
- At this time, a handle side lever is fixed to a side of the handle centering a bearing box, and separated from the handle frame. The reason is that there may occur interference within a range of a rocking angle of ball joints of the lever since the first and second handle frames may be connected to the handle shaft at a specific angle, and the lever may not be located on the handle frame.
- In the above structure, gearing means and a damper in stead of an auxiliary linkage can be utilized to enlarge the angular motion range of the handle. Furthermore, a cross joint mounted on the lower shaft can realize wide three-dimensional motion trajectories, and has a guide linkage for freedom and specified twist structure. The combination between the cross joint and the guide linkage can realize motion trajectories, which were not realized by the conventional reduction trajectories.
- At this time, the shape of the handle side lever and the front lever of the frame, which are connection parts of the auxiliary linkage using the cross joint, cannot suggest a realistic alternative method in terms of the position of the handle side lever disclosed in the U.S. patents. Particularly, shafts of the ball joints for changing a forward angular motion to a laterally angular motion of the auxiliary linkage must be arranged perpendicularly to each other.
- As described above, the apparatus for three-dimensional anaerobic exercise according to the present invention can provide three-dimensional motion trajectories suitable for the human body and allow the human body to do more improved exercise.

- The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.
- As the three-dimensional
anaerobic exercise apparatus 1,FIG. 1 shows an apparatus for breast exercise of the upper part of the human body according to a preferred embodiment of the present invention. - The three-dimensional
anaerobic exercise apparatus 1 includes an I-shapedbase frame 2 and atower 3. Aseat 4 is mounted on thebase frame 2. Handlelinkages 5 are inclinedly mounted at right and left sides of thebase frame 2 viabearings 6 in such a manner as to form an angle α in front of theseat 4, so that thehandle linkages 5 can perform an angular motion in back and forth directions. A bearing box is mounted on the front end of thehandle linkage 5, and first and second handle frames 8 and 9 are mounted in such a manner as to be rotated by ahandle shaft 10. - The first handle frame 8 is connected to the
handle shaft 10, and thesecond handle frame 9 is connected to the first handle frame 8 at an angle Θ. At this time, aside lever 11 of the handle is fixed between the first handle frame 8 and thebearing box 7 at a predetermined setting angle (which can be adjusted according to moving parts of the human body) formed with the first handle frame 8 in directions of the first and second handle frames 8 and 9 from thebearing box 7. - The upper end portion of an
auxiliary linkage 12 is connected to thehandle side lever 11 via a ball joint 13, and a ball joint 13 a is mounted on the lower end portion of theauxiliary linkage 12 in such a manner as to form a distance d from a fixedlever 14 fixed to the lower end of the front side of thebase frame 2. - an auxiliary linkage (12) connected at an upper end to the handle side lever (11) via a ball joint (13) and mounted at lower end on a fixed lever (14) fixed to the lower end of the front side of the base frame (2) via a ball joint (13 a) to form a distance (d).
- After all, when the
handle linkage 5 carries out the angular motion using a distance difference between thehandle linkage 5 and theauxiliary linkage 12, thehandle shaft 10 performs a circular motion, so that thehandle 15 mounted on the first and second handle frames 8 and 9 provides a three-dimensional motion trajectory as shown inFIGS. 3 and 4 to allow the exerciser to do three-dimensional exercise. - That is, as shown in FIGS. 1 to 4, the
handle linkage 5 is axially mounted on thebase frame 2 at the angle α or α′ for trapezoidal and angular motion, and theauxiliary linkage 12, as shown inFIG. 1 , is connected to the fixedlever 14 of thebase frame 2 via the ball joint 13 a at the predetermined distance d from the front side or the rear side of the lower portion of thehandle linkage 5. At this time, the ball joint 13 a is axially mounted in the same direction as the angular motion of thehandle linkage 5, namely, in a direction that the ball joint 13 a located at the lower portion of theauxiliary linkage 12 is perpendicular to the ball joint 13 located at the upper portion of theauxiliary linkage 12. - After that, as means for axially mounting the
handle shaft 10 at angles β and β′, thebearing box 7 is fixed on the upper end of thehandle linkage 5. - The
handle shaft 10 is axially mounted to thebearing box 7, and the first handle frame 8 is fixed to an end of thehandle shaft 10 in such a manner that an end of thehandle 15 is not directly connected to thehandle shaft 10. Thesecond handle frame 9 is connected to thehandle shaft 10 at the angle Θ in such a manner as to adjust an angle of thehandle 15 or to mount two or more handles 15. - The
handle side lever 11 is fixed between thebearing box 7 and the first handle frame 8 in such a manner as to maintain a predetermined angle with respect to the first handle frame 8. Thehandle side lever 11 is connected to theauxiliary linkage 12 via the ball joint 13, and the ball joint 13 performs a smooth angular motion similar to an angular motion of thehandle shaft 10. - Based on the three-dimensional
anaerobic exercise apparatus 1 according to the present invention, the components of the present invention for realizing the safe motion trajectories necessary for the human body in view of the side and plane as shown inFIGS. 3 and 4 will be described in more detail. - First, the angle α and α′ of the
handle linkage 5 is to obtain a trapezoidal structure for multi-joint exercise of the human body, and to induce organic composition with other components. - In case of an apparatus for exercise of the upper part of the human body, when the
handle linkage 5 is axially fixed at the angle α and α′ and performs the angular motion at angles r and r′, for the angular motion of the handle suitable for the human body, an angle range of r+r′ does not exceed 65 degrees and a motion trajectory a of the upper part of the human body does not exceed 65 cm. Therefore, the length b of thehandle linkage 5 is at least 60 cm or more. - When the
handle linkage 5 is moved at the angle of r+r′, as shown inFIG. 3 , the angle r has an influence on the angle Θ formed between thehandle shaft 10 and thesecond handle frame 9 when the handle is located at a side of the human body. On the other hand, as shown inFIG. 4 , the angle Θ is influenced by the angle α when thehandle 15 is located in front of the human body. - After all, when the angles α, β and r, the length b of the
handle linkage 5, and the motion trajectory length a of the upper part are in organic relationship one another, the reduction linkage can realize safely three-dimensional motion trajectories in view of the plane and side. - To obtain motion trajectories necessary for the human body's wrists, arms and shoulders, when the motion trajectory is seen from the side view as shown in
FIG. 3 , the angle Θ is required for offset of the angle r, and when the motion trajectory is seen from the plane view as shown inFIG. 4 , the angle α is required for offset of the angle Θ. - To improve movement of the target muscle by realizing the safely three-dimensional motion trajectories more suitable for the human body, the successive increase and decrease of the angular motion of the
handle 15 is used. - To realize the concave motion trajectories from the human body as shown in
FIGS. 4 and 5 , the motion trajectories formed in view of the plane are the concave or convex motion trajectories from the human body according to the position of the start point S as shown inFIG. 5 . To apply the motion trajectories to the human body, the first handle frame 8 for connecting thehandle shaft 10 and thesecond handle frame 9 at the angle Θ must be provided for constructing thehandle 15 corresponding to portions relative to the start point S and the end point f, and the first handle frame 8 must be fixed to thehandle shaft 10 for the safe motion trajectories. - As shown in
FIG. 4 , the apparatus requires means for mounting two ormore handles 15 for the safe motion trajectories, differently from a two-dimensional apparatus, which simply changes only the form of the handle. - That is, a
first handle 15 a starts the movement at a range wider than asecond handle 15 b and has an angular motion of 60˜120 degrees, but finishes the movement at a range narrower than thesecond handle 15 b. So, thefirst handle 15 a can increase approach of the target muscle and reduce approach of other muscle in comparison with thesecond handle 15 b, so that the human body can do exercise in various motion trajectories using one apparatus. - The first handle frame 8 is provided for mounting of two or
more handles 15, and thesecond handle frame 9 is connected to the first handle frame 8 at the angle Θ for forming the angle Θ of thehandle 15. - A kinetic approach of the components is required for the organic combination of the three-dimensional motion trajectories.
- First, differently from
FIG. 10 (prior art), as shown inFIG. 5 , the ball joint 13 a mounted on the lower end portion of theauxiliary linkage 12 is axially mounted similar to the angular motion direction of thehandle linkage 5, and the ball joint 13 mounted on the upper end portion of theauxiliary linkage 12 is also axially mounted similar to the angular motion direction of thehandle 15, so that the ball joints 13 and 13 a having the restricted rocking angle (40˜50 degrees) to the movement direction can absorb the angular motions of thehandle linkage 5 and thehandle 15 when thehandle linkage 5 and thehandle 15 perform wide angular motions. After all, the shaft of thehandle 15 and the shaft of thehandle linkage 5 are operated in a cross way to each other, and the ball joints 13 and 13 a are operated in a cross way to each other to absorb the angular motion of thehandle 15 and thehandle linkage 5, and so, the angular motion range of the handle necessary to the upper part of the human body must be set from 60 degrees to 120 degrees. - Differently from
FIG. 10 (prior art), as shown inFIG. 6 , for the safely three-dimensional motion trajectories, the length of thehandle linkage 5 and the length of theauxiliary linkage 12 are similar to each other or the same. For this, the ball joint 13 located at the upper end portion of theauxiliary linkage 12 is mounted in such a manner that thehandle side lever 11 is fixed to thehandle shaft 10 in the direction of thehandle 15 from thebearing box 7. - Otherwise, as shown in
FIG. 13 , the angular motion of thehandle 15 is increased or decreased. If theauxiliary linkage 12 is enlarged as shown inFIG. 11 , it is difficult to obtain the stable angular motion of thehandle 15. - On the other hand, if the
auxiliary linkage 12 is somewhat shorter than thehandle linkage 5, the properties of the angular motion of thehandle 15 and the compensation can be attained. - As shown in
FIG. 1 , to apply various motion trajectories necessary for the human body, thebearing box 7 is fixed to the front end of thehandle linkage 5 at the angle β or β″, and at this time, thehandle shaft 10 is axially fixed at the angle β or β″. - Considering peculiarity of the human body, influence of the components, and restrictions of range, the angle of the
bearing box 7 fixed to thehandle linkage 5 can be controlled to β or β″. - For instance, if the angles r and θ do not correspond to each other, the angle of the
handle shaft 10 is controlled to β for approach to the human body, and if the angles α and θ do not correspond to each other, the angle of thehandle shaft 10 is controlled to β′ for obtaining the motion trajectories necessary for the human body. - In the above, the basic structure of the three-dimensional
anaerobic exercise apparatus 1 is described. Hereinafter, referring toFIGS. 15 a to 16 b, means for increasing the restricted angular motion will be described in detail. - As shown in
FIGS. 15 a and 15 b, adamper 16 is mounted in place of theauxiliary linkage 12 to increase the angular momentum of thehandle 15 and resistance of the exerciser within the restricted section. An adjustable screwingpart 17, which uses a male and female screwing method, is used so as to control the angular motion range of thehandle 15. - In
FIGS. 15 a and 15 b, the angular motion more than 180 degrees is impossible, but as shown inFIGS. 16 a and 16 b, the upper andlower bearing boxes 7 are in close contact with each other, and the spur gears 19 and 20, which are axially fixed to thehandle shaft 10 and the side lever shaft 18 in respective, are connected to the upper andlower bearing boxes 7 respectively, so that the angular motion can be increased by the gear ratio. - The
handle shaft 10 and the side lever shaft 18 must be axially mounted in parallel with each other, and if thehandle shaft 10 and the side lever shaft 18 have the same trajectory in, the basic three-dimensional motion trajectories, as shown inFIGS. 16 a and 16 b, the fixedlever 14 of thebase frame 2 is located in the opposite direction to the shafts. -
FIGS. 17 a and 17 b show an example where the cross joint 21 is applied for allowing thehandle linkage 5 to perform both a back and forth movement and a lateral movement. Ashaft 21 a of a side of the cross joint 21 is axially mounted on thebearing 6, and ashaft 21 b of the other side is axially mounted to the lower end portion of thehandle linkage 5. - A
connection lever 22 is axially fixed to an end portion of the front side of theshaft 21 a, and the other end portion of theshaft 21 a is connected to the lower end portion of theauxiliary linkage 12 via the ball joint 13 a. At this time, theconnection lever 22 is in an L shape for absorbing the rocking angle of the ball joint 13 a. - Meanwhile,
FIG. 18 shows an example where the spur gears 19 and 20 axially mounted to the bearingboxes 7 ofFIGS. 16 a and 16 b and the cross joint 21 ofFIGS. 17 a and 17 b are combined with each other. - In
FIG. 19 , fixingpieces handle linkage 5 and thebase frame 2 in the state ofFIGS. 17 a and 17 b, and anotherauxiliary linkage 27 is mounted between the fixingpieces auxiliary linkage 27 is to induce the three-dimensional motion trajectory of thehandle linkage 5 using the characteristics of the cross joint 21. - Referring to
FIGS. 20 a and 20 b, the trajectory of thehandle 15 can induce the trajectory as shown inFIG. 21 b according to the position of the fixingpieces 24 shown inFIG. 21 a. - As described above, the conventional two-dimensional anaerobic exercise apparatus cannot provide a safe motion trajectory necessary for the human body as using single motion trajectory and single resistance, but the three-dimensional anaerobic exercise apparatus according to the present invention can safely apply resistance to the human body by using means such as a cam.
- The three-dimensional anaerobic exercise apparatus according to the present invention can completely control the angular motion of joints of the human body, and so, can control various patterns, such as successive increase and decrease of resistance as providing the safe motion trajectories.
- Furthermore, the present invention can overcome the restrictions and overload problem of the two-dimensional anaerobic exercise apparatus as having two or
more handles - The four-rod linkage concept proposed in the application previously filed by the inventor of the present invention secures the safe motion trajectories, but has several problems in that a manufacturing process of the apparatus is very complicated and manufacturing costs are too expensive. As a result of studies of the four-rod linkage, restrictions of reduction can be overcome by approach of the reduced-rod linkage concept. So, the reduced-rod linkage concept can be commercially used since the manufacturing process is simple and the manufacturing costs are inexpensive even though the reduced-rod linkage concept requires various data for motion trajectories corresponding to those formed by the human body.
- In the conventional reduced-rod linkage concept, the entire size of the linkage is large because the handle has a restriction in change of angle. However, the present invention can increase approach to the human body through a free change of angle of the handle, can considerably reduce the entire size of the linkage, and increase convenience when the exerciser seats on the seat of the apparatus.
- In addition, the conventional two-dimensional anaerobic exercise apparatus has a restriction in the motion trajectories of the handle in view of the plane, and cannot obtain the angle necessary for the human body as the angle of the handle is influenced by the angular motion of the handle linkage. However, the present invention can realize the motion trajectories. necessary for the human body by providing means for utilizing various data of the three-dimensional motion trajectories provided by the conventional two-dimensional anaerobic exercise apparatus or the conventional three-dimensional anaerobic exercise apparatus having the four-rod linkage, thereby contributing to well-balanced growth of the human body.
- While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
