Abstract
An elevation mechanism, for changing the elevation angle of an attachable container subassembly, has an outer housing having an integral portion for mounting the container subassembly, and an inner housing having an exterior surface about which the outer housing is rotatably supported. A motor within the inner housing supplies torque to a gear train, which includes a planetary gear system for rotating the outer housing and the container subassembly attachable thereto, with respect to the inner housing. The inner housing can be fastened to a surface, generally in the vertical plane, with respect to which surface the rotating outer housing moves the container subassembly in adjustable elevation disposition.
