ARM OR- LEG EXERCISER Filed July 17, 1952 V III (Man 45 INVENTOR.

United States Patent O 3,176,986 ARM R LEG EXERCSER Eohdan Posatsky, R0. Box 553, Santa Clara, Calif. Filed July 1'7, 1962, Ser. No. 216,521 Claims. (Cl. 272-80) This invention relates to mechanical exerciser devices and more particularly to an arm or leg eXerciser.

It is an object of the present invention to provide an arm or leg exerciser that will be especially adaptable for physical therapy and will be eflicient in operation whether in vertical or horizontal position.

Another object of the present invention is to provide an arm or leg exerciser that is adjustable for varying individual requirements.

A further object of the present invention is to provide an arm or leg exerciser that can be mounted on a frame and attached to a door by means of C-clamps.

Other objects of the invention are to provide an arm or leg exerciser bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and eiicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:

FIGURE l is a Vertical view of the present invention shown in elevation and partly broken awa` FIGUREI 2 is a fragmentary side View taken on the lines 2 2 of FIGURE 1;

FIGURE 3 is a top plan view of the frame;

FIGURE 4 is a view taken on the lines 4-4 of FIG- URE 3; and

FIGURE 5 is a side view of FIGURE 3.

Referring now more in detail to the drawing, an exerciser 1G made in accordance with the present invention is shown to include a base plate 12 with a U-shaped bracket 14 iixedly secured centrally of the upper surface. An elongated eye rod 16 is freely received Within bracket 14 and is pinned by pivot pin 13 which is received through eye rod and bracket 14. A shoe 2d having an asbestos lining 22 secured to its bottom surface is in frictional engagement with the arcuately curved surfaces of bracket 1d. A hollow and circular cup 2d abuts with the top of shoe Ztl and freely receives a coil spring 26. The upper end of coil spring 26 is freely received by cup 2S of circular configuration. A knurled tension spring nut 30 is threadingly received by eye rod i6 above cup 28 thus providing adjustable tension upon spring 26. An internally threaded bushing 32 is threadingly received by eye rod 16 and provides for adjustment in height of exerciser 10 and a lock nut 34 secures it in position. An elongated tubular sleeve 3d is freely received at the upper end of eye rod l5 and a spherical knob 38 is iixedly secured to the upper end of sleeve 36. A sandal is secured to sleeve 36 below knob 3S by a pair of circular clamps 41 which are adjustable so that sandal 40 may be slid up or down upon sleeve 3d. Sandal 40 has a plurality of elongated and rectangular slots 42 which receive adjustable straps for holding the limb of an individual. A pair of parallel bars 46 having a plurality of openings 48 are secured to a pair of parallelly spaced apart cross bars Si) having a plurality of openings 52. Bars 46 with cross bars 50 provide frame means for clamping to a support structure such as a door or a chair. A pair of clamps 54 are secured one to each' bar 46 and are adjustable by threaded screws S6. Clamps 54 are secured to bars by fasteners 5S.

As previously described, the frame means comprising the bars ld and the cross-bars 52 is secured to a door, chair or any suitable support structure through the clamps 54. The base of the bracket A can be secured to the 3,176,986 Patented Apr. 6, 1965 'ice frame by means of suitable fasteners passed through the holes 4S.

In operation, the individual using the device places his leg or arm in the sandal 4i) and straps it into place with the straps provided. When placing a foot into the sandal 4), the position of the foot will be to have the heel rest against the wide Wall section and the toes project toward the narrow wall section. With an oscillating motion he carries sleeve 36 back and forth and the asbestos lining 22 provides friction against the arcuate curved vertical sides of bracket 1:4. When a chair is desired to be used, the fasteners are placed into the openings 48 and the exerciser is secured to the chair. When it is desired to suspend bars 45 and their cross bars Sil clamps 54 are placed over the edge of a door and the clamp screws 56 are rotated until clamp 54 is secured to the door.

It will be noted that the radius of bracket ld may be taken from the pivot pin 18 or directly beneath depending upon the desirability of forward or backward motion to increase the tension.

While various changes may be made in the detail construction it shall be understood that such changes shall be within the spirit and scope of the present invention as deliri-ed by the appended claims.
