Abstract:
A wheelchair includes a seat carried by a frame including at least one front wheel and opposed rear wheels. A circular handrim is coupled to one of the rear wheels with spaced-apart connecting pins. A framework is secured to the handrim, and a ratchet operatively couples an inner end of a lever to the framework. The lever extends upwardly from the ratchet to the outer end allowing a user seated in the seat of the wheelchair to grasp the outer end of the lever and move the lever between a first position and a second position. The ratchet acts on the framework to impart rotation to the one of the rear wheels in response to movement of the lever between the first and second positions.
