Abstract

A leg exerciser for the wheelchair bound includes a frame which is placed on the floor. The portions of the frame which touch the floor may be covered with protective material. The frame has a vertical bracket at one end thereof formed as a rectangle about an open interior. This bracket is mounted between the small front wheels and the larger main wheels of a wheelchair. A portion of each of the front wheels is securely retained in the bracket'"'"'s open interior. This arrangement thus serves to fix the position of the wheelchair relative to the exerciser and to prevent relative movement between the wheelchair and the exerciser. The forces exerted on the exerciser are directed so that the front wheels of the chair are caused to engage the bracket which prevents the rearward movement of the chair and any forward movement of the exerciser. Two shock absorbers provide resistance against radius arms to which foot pedals are attached. Return force is provided to cause the foot pedals and the radius arms to return to an initial resting position.

Claims

1. A leg exerciser for the wheelchair bound comprising a frame including two lateral bars and one end member and one end bar connected across said lateral bars;

one of said end members comprising of a vertical rectangular bracket mounted on one end of said lateral bars for receiving and retaining the front wheels of a wheelchair;

first and second radius arms mounted on respective one of said parallel members;

foot pedal means for excerising the legs of a wheelchair user attached to each of said radius arms;

a shock absorbing damper attached between each of said radius arms and said parallel members for causing resistance against the compression caused by pressure on said foot pedal; and

return force means connected between said frame and each of said radius arms for generating a return force against said foot pedal means.

2. The exerciser of claim 1 wherein said return force means including a spring.

3. The exerciser of claim 1 wherein said return force means including an elastic band.

4. The exerciser of claim 1 wherein said bracket includes a moveable section to assist in positioning said wheelchair.

5. The exerciser of claim 1 wherein the vertical rectangular bracket may be positioned behind the front wheels of a wheelchair so that the force exerted on said foot pedals by a wheelchair user will cause a portion of the front wheels of a wheelchair to securely engage said vertical rectangular bracket.

6. A leg exerciser for the wheelchair bound comprising:

frame means for supporting a leg exerciser;

said frame frame means including an appertured means of attachment integrated into said frame means for retaining the front wheels of a wheelchair therein, thereby forming a wheelchair/exerciser combined unit, resistance means to exercise the legs attached to said frame for providing exercise resistance to the legs of a person;

a return force means attached to said resistance means and to said frame of said exercise device for generating a return force to return said resistance means to an initial position and foot pedal means for supporting a user'"'"'s foot attached to said frame.

7. A leg exerciser for the wheelchair bound comprising:

a frame having two parallel support members and two end members connected across the ends of said parallel members;

a vertical bracket mounted on one of said end members, said vertical bracket including first and second end sections mounted on one of said end members and a lateral cross section mounted on said end sections parallel to and a distance above said end member forming a space for retaining a portion of the front wheels of a wheelchair therein, first and second radius arms connected to said frame, each of said radius arms having a foot pedal means attached thereto for supporting the user'"'"'s feet;

first and second shock absorber means connected between said frame and said radius arms for providing resistance to said foot pedal means;

return force generating means attached to said frame and each of said radius arms for exerting a force to return the user'"'"'s foot to a rest position.

8. The exerciser of claim 7 wherein said frame is mounted on a floor and includes protective means to prevent said frame from sliding on a floor and to protect said floor.

9. The exerciser of claim 7 wherein said vertical bracket includes at least one hinged section means therein for moving a portion of said vertical bracket to assist in positioning the front wheels of a wheelchair for proper engagement with said vertical bracket.
