A STOWABLE EXERCISE APPARATUS
BACKGROUND OF THE INVENTION
THIS invention relates to a stowable exercise apparatus.
Numerous different exercising machines are known in which a person exercises against his or her own mass on an inclined rail system A sliding board moves on rollers up and down along the rail system by manipulating handles at the end of ropes attached to a system of pulleys The rail system is connected to a support post at different elevations in order to vary the difficulty of exercising by adjusting the incline of the rail system The resistance of the apparatus is further varied by means of rubber bands which are connected between the sliding board and the rail system A typical exercising apparatus of this type is disclosed in US patent 4,911 ,438
In the domestic environment in which most of these exercise apparatus are customarily used, it is desirable that such apparatus be made as compact as possible when in the stowed position It is an object of the invention to provide a compactly stowable exercise apparatus which does not sacrifice range of travel and versatility when in the deployed position in favour of stowabihty
SUMMARY OF THE INVENTION
According to the invention there is provided a stowable exercise apparatus comprising a front stand, a rear stand, rail means extending between the front and rear stands, a sliding board slidable along the rail means between the front and rear stands, and a securing arrangement for securing a front end of the rail means at vertically spaced apart locations along a post portion of the front stand for varying the inclination of the rail means, the rail means including first and second telescopic beams which are movable between a stowed retracted position and a deployed extended position
In a preferred form of the invention, the front stand is arranged to pivot over the sliding board towards the stowed position, with the post portion of the front stand, the sliding board and the telescopic beams being substantially parallel when in the stowed position
Conveniently, the first and second telescopic beams are arranged to telescope into a length which is substantially equal to the length of the sliding board, with the length of the sliding board being predominantly determinative of the stowed length of the apparatus
Advantageously, a support strut extends between a base of the front stand and a rearward end of the first telescopic beam, the support strut being pivotably connected to the base of the front stand on a pivot arm which allows the front stand to be folded over the sliding board when in the stowed position
The rear stand is typically provided with a pair of wheels for facilitating the stowing and deploying operations, and conveniently comprises a lower base bar fitted with wheels in the form of rotary sleeves and a parallel upper base bar surmounting the lower base bar with a pair of pipe sockets extending
through the upper and lower base bars for interchangeably receiving the legs of a removable foot board or a removable handle bar set
A locking pin is advantageously provided for locking the first and second telescopic beams in the extended position

DESCRIPTION OF EMBODIMENTS
Referring first to Figure 1 an exercise apparatus 10 of the invention comprises a front stand 12, a rear stand 14 and an inclined telescopic rail assembly 16 extending between the front and rear stands The front stand 12 includes a front base bar 18 from which a vertical graduated post 20 extends, the post 20 terminating in a top bar 22 A padded sliding or glide board 24 is fitted with front and rear wheelsets 26 and 28 respectively which allow it to travel smoothly up and down the telescopic rail assembly 16 The telescopic rail assembly is formed from a rear beam 30 which is arranged to telescope within a front beam 32 A sliding bracket assembly 34 is pivotably mounted to an end extension of the front beam on a pivot assembly 35, and includes a sprung pin 36 which is arranged to locate within a series of vertically spaced apertures 38 formed along the post for enabling the inclination of the rail assembly to be varied A cross bar 40 carries a lower pair of footbars 42, and is formed with a pair of pipe sockets 44 for accommodating a removable upper handlebar set 46 in a click fit A pair of pulleys 48 are mounted to opposite ends of the cross bar 40, and in conjunction with a centre pulley 50 supported on the front bar extension and a pair of horizontal side pulleys 52 mounted to the base of the sliding board form a pulley system with a rope 54 which terminates in handles 56 Increased versatility is provided by a pair of side pulleys 58 similarly mounted to the sliding board 24
A pair of continuous elastic resistance bands 60 extend around upper and lower pair of stub axles 64 and 66 extending from the respective front beam 32 and rear wheelset 28 of the sliding board 24 The number and tension of the elastic bands 60 may be varied to vary the difficulty of exercising
The rear stand 14 includes a lower base bar 68 surmounted by an upper base bar 70 A pair of wheels in the form of rotary sleeves 72 are mounted rotatably to opposite ends of the lower base bar 68 and a pair of socket-defining pipes
74 extend transversely through both the upper and lower base bars The socket-defining pipes are arranged to receive, in a removable snug fit, a pair of legs 76 extending from a foot or squat board 78 The extended socket-defining pipes 74 in conjunction with the lower and upper base bars 68 and 70 provide a sturdy mounting facility for the squat board for enabling squat-type exercises to be performed against significant resistance A support strut 80 is mounted pivotably between a goose neck 82 extending from the front base bar 18 on a pivot pin 83 and a U-shaped trunnion plate 84 mounted towards a rear end of the front telescopic beam 32
Additional fittings include a pair of inwardly foldable squat grips 88 extending from the base of the sliding board 24, a pair of fixed foot straps 90 carried on the sliding board, a pair of removable leg straps 92 which can be interchanged with the handles 42, and a separate cross bar 94 which is used to perform bench press exercises and the like in conjunction with the handles 42 and the side pulleys 58
The stowing operation will now be described with reference to Figures 2A to 7
As is clear from Figures 5 to 7 both the front outer telescopic beam 32 and the rear inner telescopic beam 30 have rectangular profiles, with the inner beam 30 being formed with a lower recess 96 A U-shaped plastics collar 98 is mounted to the outer beam 32, with the inner portion of the collar 98 locating between the two beams The end of the inner beam 30 is fitted with a flanged plastics cap 99, with the flanged portion of the cap 99 locating against, and arrange to slide along, the inner surface of the outer beam 32 The collar 98 and the cap 99 have a relatively low coefficient of friction so as to enhance the sliding operation A sprung locking pin 100 is also mounted to the underside of the outer beam 32, and is arranged to extend through a complemental aperture 102 defined in the inner beam to hold the beams in an extended locked position As can be seen in Figure 6 the recess 96 provides sufficient
space for the U-shaped trunion plate 84 to be bolted firmly against an inner lower surface of the outer beam 32 with the arms of the U extending through corresponding slots 104 defined in the beam 32
Stowing of the exercise apparatus is commenced by first raising the sliding bracket 34 up to its maximum height to achieve maximum incline of the rail assembly The locking pin is then gripped in one hand and retracted, whilst the opposite hand grips the squat board 78 and jerks it forward to cause the rear beam 30 to telescope within the front outer beam 32 to the completely telescoped position illustrated in Figure 2A in which no part of the front beam 32 protrudes, and the sliding board 24 spans the distance between the removable handlebar set 46 and the squat board 78 Sliding friction is reduced during this operation by virtue of the roller sleeves 72
The locking pin 36 on the sliding bracket is then retracted and the sliding bracket is lowered down the length of the post 20 using the lowering and raising handle 108 extending from the bracket to arrive at the Figure 2B position In this position it can clearly be seen how the entire front stand 12 is able to pivot around the goose neck pivot pins 83 and the pivot assembly 35 connecting the sliding bracket to the front beam 32 to the stowed position illustrating in Figure 3 In this position, the squat board 78 serves as a stand, and the front stand 12 the sliding board 24 and the telescoped front and rear beams 32 and 30 are in a parallel adjacent position
A significant advantage of the stowable exercise apparatus of the invention is that it allows for a full range of movement during the multiplicity of exercises, whilst at the same time enabling the exercise apparatus to be collapsed into a compact stowable configuration in which it can be comfortably stored in a standard cupboard, for instance The extended telescopic rail assembly accommodates a full length sliding board which comfortably accommodates an exerciser in the fully seated and prone lying positions At the same time, there
is sufficient travel of the sliding board along the rail assembly to allow for a full range of exercising movements, regardless of whether the pulley system is used or not.
