ABSTRACT:
A portable power-operated lift and presenting mechanism has a base that is placed on the floor of an automobile trunk. A carriage moves between an elevated position and a lowered, transport position when a scissors jack connecting the carriage to the base respectively expands vertically and contracts vertically, expanding horizontally. The scissors jack is selectively power-operated, by a reversible electrical motor, to expand and contract vertically. The carriage has drawer slide assemblies on which is mounted a platform capable of supporting a heavy and bulky article. The platform is movable by the drawer slide assemblies, when the carriage is in an elevated position, between a retracted position in which the platform is generally over the base and within the trunk, and a presenting position in which the platform extends out from over the base, generally out of the trunk.
