Abstract
A leg assembly configured to be used with a wheelchair that may be constructed of various mechanical and manual powered components to reduce the cost and unreliability of motor, electric, or otherwise non-manual powered adjustable wheelchairs. A combination wheelchair and leg assembly that may be constructed of various mechanical and manual powered components. The leg assembly disclosed may alternatively be motor powered.
Claims20
A leg assembly configured for use with a wheelchair having first and second wheel support beams, the leg assembly comprising:
- a leg support post, comprising:
- an outer tube having a proximal outer tube end and a distal outer tube end;
- an inner tube being configured to slide within the outer tube and having a distal inner tube end, the inner tube protruding from the distal outer tube end such that the distal inner tube end is not contained within the outer tube;
- and
- a foot rest secured to the inner tube proximate the distal inner tube end;
- a mounting assembly configured to be attachable to one of the first and second wheel support beams of the wheel chair;
- wherein the leg support post is connected to the mounting assembly such that the leg support can be rotated therearound between a first, retracted position in which the wheelchair user's leg is meant to be supported in a bent position and a second, extended position in which the wheelchair user's leg is meant to be supported in a less bent position, the mounting assembly being configured such that when the leg support post is moved from the first, retracted position toward the second, extended position the inner tube slides within the outer tube such that the distal inner tube end moves further away from the distal outer tube end, when the leg support post is moved from the first, retracted position toward the second, extended position the leg support post does not pivot about the proximal outer tube end which results in the proximal outer tube end moving through an arcuate path about the mounting assembly.
