  • Patent number: 4807712
    Abstract: A self-propelled table for carrying and/or lifting/lowering objects for invalid people having a hollow plastic upper enclosure which is padded at the edges and upon the surface of which contains anti-slip recesses and a joystring assembly. The lower portion of this assemblage is attached to a vertically mounted, telescoping tubular assembly which may be either fixed or supplemented with a motor-power assembly with which to adjust the height-away-from-the-floor of the uppermost serving surface. The bottom of the tubular assembly is attached to the upper portion of a hollow plastic lower enclosure which contains wheels, motors, batteries, and electronic circuits to translate the electronic signals from the joystring into meaningful wheel motions. Pulling the free end of the joystring causes the invention to propell itself and it's load in the same direction that the joystring was pulled; thereby providing handicapped people with the ability to perform simple tasks unassisted.
