Abstract:
1. A lift portable patient comprising: a base, a mast extending from the base, a boom extending from the mast, the boom being structured to support a cradle for lifting a patient, support legs extending from the base, a mechanical controller operatively connected to the legs to move the legs throughout a first range of motion between a first spread apart position and a second spread apart position, the mechanical controller having an anti-back drive including a movable member and a fixed member, the movable member pivotally supporting a pin that is selectively engageable with one of a plurality of slots in the fixed member to prevent inadvertent movement of the legs, a disengagement feature operative to disengage the legs from the anti-back drive so as to enable movement of the legs throughout a second range of motion between the second spread apart position and a substantially closed together position, the disengagement feature comprising a slideable shaft supporting a link, the mechanical controller comprising a leg rotation member supported in relation to the slideable shaft, the slideable shaft being operable in a first position, wherein the link engages the leg rotation member to permit the operation of the support legs via the first range of motion, and a second position, wherein the link disengages the leg rotation member to permit the operation of the legs via the second range of motion, the lift being foldable into a compact form for ease of transportation and storage by folding the boom in relation to the mast so that the boom is folded toward the mast and folding the mast in relation to the base so that the mast is folded toward the legs.
