ABSTRACT:
Apparatus is provided to assist a person in rising from a seat to a standing position that uses muscles other than leg muscles to accomplish that purpose. The device is portable and may serve as a walking stick or cane in addition to its rising assisting function. The device has a long lever or element with a broad flat enlargement at one end to fit under the buttocks. At the other end is an upright member to be grasped and pushed fore and aft in a rocking motion. On a forceful forward motion, as the free end of the lever is depressed, the bottom of the lever is forced against the upper forward edge of the seat, acting as a fulcrum to force the buttocks upward at the second end of the lever. The torso and arm muscles are thus helping the leg muscles in elevating the person to a standing position.
