The further embodiment of the device comprises an urging device which urges the second member away from engagment with the surface across which the wheelchair is operated.
Claims18
A device for operating a wheelchair with one arm comprising a first member engagedly attached to a frame of the wheelchair and a second member movably attached to the first member such that while the device is attached to the frame, the second member frictionally engages a surface across which the wheelchair is operated.
A device for operating a wheelchair with one arm comprising:
- A. an elongated first member adjustable in length and having means on both ends for an engagedly attachment to a frame of the wheelchair;
- B. an elongated second member having a knob on one end and a frictional means on another end;
- wherein the second member is pivotally and slidably attached to the first member and wherein the second member frictionally engages the surface across which the wheelchair is operated.
A device for operating a wheelchair with one arm comprising:
- A. an elongated first member comprising tubing adjustable in length and having on both ends means to be engagedly attached to a frame of the front of the wheelchair;
- B. a second member comprising a staff having a knob on one end and a friction means on another end;
- C. a third member comprising tubing;
- and
- D. an urging member;
- wherein the first member is attached to the second member by the third member, wherein the third member has one end fixedly attached to the first member and another end pivotally and slidably attached to the second member such that when the device is attached to the frame of the front of the wheelchair, the friction means of the second member is cabable of frictional engagement with the surface across which the wheelchair is operated by frictionally engaging the surface around the periphery of the front of wheelchair and wherein the urging means urges the second member away from the frictional engagement.
