Abstract:

A motorized walker/wheelchair having wheels, an A-frame which has a driven a leg and a rolling leg which join at a vertex. Rising from one of the legs there is a control handle assembly. A motor wheel, or optionally two motor wheels, are provided at the lower portion of the driven leg of the A-frame. A caster wheel extends from the bottom of the rolling leg. Provision is made for a seat which is secured at its rearward portion to the seat support spreader. Hand controls are provided to the handle support which in turn control the operation of at least one motor driven wheel, or optionally, to separate motors driving two wheels. The two legs, the driven leg and a rolling leg, are joined at a pivot point at their vertex. Beneath the pivot point is a leg bridge which folds, thereby permitting the bridge beam to be raised upwardly which subsequently permits the driver wheel-caster arrangement to move in close proximity to each other while the seat folds upwardly and the entire unit transfers itself into the portable or folded mode.
