The pivot bolt 94 extends through a hole 100 provided in the top plate 76 and then is slidably received by hole 102 provided in the plate 82 and is threadably received by a hole 104 provided in the bottom plate 72. With this construction, the plate 82 will rotate about the pivot bolt 94 relative to the plates 72, 80 and 76 which are fixedly joined together.
A locking pin 108 having a head portion 109 is mounted to a pull handle 118 through a coil compression spring 114 and a lock washer 116. The locking pin 108 is sized to extend through hole 112 provided in top plate 76 with head 109 resting in a selected index hole 106 provided in plate 82 when pull handle 118 is in the resting position. The index holes 106 are sized to receive the head 109. When the pull handle 118 is pushed down against the resilient force of spring 114, the head 109 is forced out of the selected index hole 106 through opening 110 provided in the bottom plate 72. The plate 82 can then be rotated about the pivot bolt 94 to a selected position and the pull handle 118 released. The spring 114 causes the head 109 of pin 108 to move upwards into a newly selected index hole 106.
A latching mechanism 120 is provided to lock the slide portion 86 to a rail 12 as described below. The latching mechanism includes a latch member having an end portion 124 for extending into a cutout portion 126 provided in the plate 82 and slide portion 86. The end portion 124 is shaped and sized to fit within a keyway 152 as shown in FIGS. 17 and 18. A cam lever arm 128 includes a handle portion joined to two spaced apart arms 132 and 134. A pin 136 is sized to be slidably received by holes provided in arms 132 and 134. The pin 136 includes a threaded hole 138. A bolt 140 is slidably received by a hole 142 provided in middle plate 82 and a hole 144 provided in the latch member 122 and then is threadably received by hole 138.
The arms 132 and 134 of the handle 130 have a cam shape such that when the handle is lifted, the end portion 124 of the latch member 122 is allowed to rise and when the latch member 122 is moved to the down position, the end portion 124 is forced downwardly.
The rails 12A, 12B, 12C and 12D are all of identical construction. These rails will be collectively referred to as element 12 in FIGS. 12 and 13. The rails 12 include a central cavity 146 which extends longitudinally from one end of the rail to the opposite end of the rail. The rail 12 further includes wheel races 148 which extend from one end of the rail 12 to the opposite end of the rail 12 for rollably receiving wheels 34 of the shuttles 14. The rails also include longitudinal slots 150 extending from one end of the rail 12 to the opposite end of rail 12 for slidably receiving the wheel support blocks 30 of the shuttle 14. The rails 12 further include a longitudinal keyway provided on each side of the rail 12 for receiving the slide portion 84 or the slide portion 86 of a rotatable slide 20 as shown in FIG. 14.
At each end of each rail 12, an end plate 154 is mounted to the rail 12 with screws 156 as shown in FIG. 14. Two opposed axle support plates 158 are secured to the end plate 154 as shown in FIGS. 12 and 14. An axle 160 is mounted within aligned holes provided in the axle support plates 158 and pulleys 162 are rotatably mounted on the axle 160 between the axle support plates 158 as shown in FIGS. 12 and 14.
Slots 164 and 166, provided in end plate 154, as shown in FIG. 14, receive the locking portions 74 and 78, respectively, of the rotatable slide 20 (shown in FIG. 11). With this arrangement, the locking portions 74 and 78 prevent the rotatable slide 20 from sliding on the rail 12 in which the locking portions are mounted. A shroud 168 is threadably secured to a base plate 170 positioned below the axle support plates 158 with screws 172.
An end of the shroud 168 locks the locking portions 74 and 78 in the positions shown in FIG. 15. The shroud 168 prevents the locking portions 74 and 78 from being disengaged from the slots 166 and 164.
With the arrangement shown in FIG. 2, the locking portions 74 and 78 of rotatable slides 20A and 20C, as shown in FIG. 2, are locked on the outer rails 12A and 12D, respectively. The locking portions 74 and 78 of rotatable slide 20B are locked on rail 12B.
One side of the rotatable slide 20 is locked to a rail 12 as described above. The other side of the rotatable slide is releasably locked to an adjacent rail with the end portion 124 of the latch member 122 resting in the keyway 152. The handle 130 has a cam portion resting on the latch member 122. When the handle 130 is rotated upwardly, as shown in FIG. 17, the latch member 122 rides freely within the keyway 152, as shown in FIG. 17. When the handle 130 is rotated to the downward position as shown in FIG. 17, the latch member 122 is forced into frictional engagement with the wall 174. With latch member 122 in the raised position, the rotatable slide 20 will slide in the keyway 152 of the rail 12. When the latch member 122 is in the downward position, as shown in FIG. 18, the rotatable slide 20 is prevented from moving in the keyway 152.
As shown in FIGS. 1 and 2, the rotatable slide 20A is positioned with the latching mechanism 120 engaging rail 12B. The rotatable slide 20B is positioned with the latching mechanism 120 engaging rail 12C. Under normal conditions, the latching member 120 is positioned with the handle 130 in the downward position thereby locking rotatable slide 20B to both rails 12B and 12C. The rotatable slide 12C has the latching mechanism 120 in engagement with rail 12C. Under normal conditions, the latching members 120 of rotatable slides 20A and 20C are positioned with the handle 130 in the raised position thereby allowing rotatable slides 20A and 20C to slide on rails 12B and 12C, respectively.
Resilient cords 176 extend longitudinally through the rails 12 within cavity 146 as shown in FIGS. 12 and 19-21. The resilient cord 176 extends around a pulley 162 through an opening 178 provided in a cord guide plate 180 (shown in FIGS. 12 and 14) and is attached to a ball connector 182.
The ball connector 182 is shown in FIGS. 22 and 23. A ball 184 having a threaded shaft 186 is connected to a resilient cord attachment member 188 through a hole 190 with a nut 192. A pull strap 194 is connected to the cord attachment member 188 through an opening 196. The cord 176 is connected with the cord attachment member 188 by looping an end of the resilient cord 176 through an opening 198 provided in the cord attachment member 188 and then attaching the end of the resilient cord 176 to the cord 176 with a crimp 198. A clamshell cover having two halves are joined together to cover the connection of the cable 176 with the cord attachment member 188.
An end of the resilient cord 176 may be connected to a shuttle 14 by inserting the ball 184 into a keyhole slot 202 as shown in FIGS. 4-6, and as shown in FIG. 21.
When not connected to a shuttle, the resilient cord 176 rests against the cord guide plate 180 with the clamshell cover 200 preventing the ball connector 182 from being retracted through opening 178 as shown in FIG. 20.
In operation, the rails 12A, 12B, 12C and 12D may be angularly oriented with respect to one another with rotatable slides 20A, 20B and 20C. Two configurations of many are shown in FIGS. 1 and 2. To adjust the angular orientation, the pull handle 118 is pushed downwardly causing the head 109 of pin 108 to be moved out of a selected index hole 106. The plate 82 can then be rotated with respect to plate 80. When the desired angular orientation is achieved, the pull handle 118 is released allowing the head 109 to be moved into a newly selected index hole 106.
In order to allow one rail to slide along the edge of an adjacent rail, the handle 130 of the latching mechanism 120 is lifted, thereby releasing the end portion 124 from frictional engagement with the wall 174 of the rail 12. As described above, in normal operation, the rotatable slide 20B is locked to rail 12B and is latched to rail 12C to prevent the rotatable slide 20B from sliding. If desired, the rotatable slides 20A and 20C have the latching mechanism 120 manipulated to a released position allowing the rotatable slides 20A and 20C to slide on rails 12B and 12C, respectively to a selected position. When the rails are in the selected position, the latching mechanism 120 is manipulated to the locked position thereby locking the rails in the selected position.
When it is desired to have a tension resistance on either end of shuttles 14, resilient cords 176 are attached to a shuttle 14. An example of this is shown in FIG. 2. In a preferred embodiment, three resilient cords are provided. The amount of resistance can be selected by hooking up a selected number of resilient cords 176 to the shuttles 14.
Further, the angular orientation of the hand grip 16 and toe hold 18 can be rotated by lifting the adjustment pin 54 to allow the pin 54 to move into a selected index hole 56. When the desired rotation is accomplished, the pin 54 is released and the pin 54 rests in a selected index hole 56.
As illustrated in FIGS. 1, 2 and 3, many configurations of the full body exercise equipment 10 can be selected. This equipment provides exercise for the whole body and is very effective in increasing muscle mass, improving balance and coordination, increasing range of motion and cardiovascular capacity.
While the fundamental novel features of the invention have been shown and described, it should be understood that various substitutions, modifications, and variations may be made by those skilled in the arts, without departing from the spirit or scope of the invention. Accordingly, all such modifications or variations are included in the scope of the invention as defined by the following claims:
