Abstract

The propulsion system for wheelchairs comprises a single driven wheel which is attached to the front frame of the chair. The two small front wheels are lifted off the ground so the additional wheel can steer and drive the chair. The wheel is controlled by a vertically mounted rod reciprocating in a cylinder. The rod is pumped up and down by the handicapped person and this motion is transmitted to a bicycle-type chain via a series of ratchet wheels. The rotation of the handle alters the position of the wheel to steer the chair.
