ABSTRACT:
Disclosed is a mechanism for raising and lowering a patient support including a base having two spaced posts extending upwardly, a sliding sleeve on each base post and a cross member fixed to and extending between the sleeves. An actuator is located between the base and the cross member to move the cross member vertically with respect to the base. A horizontal member located above the cross member is slidingly moveable with respect to the sleeves and includes guides to capture the sleeves. A pulley is provided on the cross member and supports a chain or belt, fixed to the base at a first end and at the other end to the horizontal support. As the actuator raises and lowers the cross member, the upper support is raised and lowered at a greater speed. On the base is a reversible fold down pole to assist the patient in raising and lowering themselves.
