Abstract
Abstract Lifting apparatus adaptable for aiding an ambulatory handicapped person. The apparatus may accommodate a person between a sitting position and a standing position. The apparatus aids in raising or lowering the individual between the two positions. The apparatus includes a pair of arm rests for engaging an individual beneath the junction of the arm and shoulder. The apparatus provides lateral and vertical movement of the rests. The vertical motion of the rests responds to a first piston means and the lateral motion to a second piston means with the start and stop operation controlled directly by the individual.
