Abstract
Abstract A bath lift for assisting invalid persons into and out of a bathtub employs a portable hydraulic jack clamped to a rim portion of the bathtub and supported on a floor surface by a nonslip base. An open center seat is attached to the extensible portion of the jack by a suspension member. A leg support-stop attached to the seat is rotatable from a position which allows safe seating of the invalid to a position which supports the legs of the invalid while the invalid is being placed into the tub. The components are adapted for easy disassembly and reassembly.
