Abstract
A motorized lifting device for loading and unloading articles from automobile trunks has a floor frame acting as a base for a pair of upstanding platform supports each of which has a flange. A carriage having a plurality of rollers is reciprocally mounted on each upstanding platform support such that at least two spaced apart rollers are on one side of the flange and at least one roller is on the other side of the flange. The flange, therefore, acts as a guide for the carriages when moving along the upstanding platform support. A platform frame is attached to the carriages and a platform rests on the platform frame. Lifting is achieved through means of a cable attached to each carriage, strung over a pulley on each upstanding platform support that is then wound onto a spool rod mounted to the upstanding platform supports. The spool rod is rotated by means of an electric motor powered by electricity from the automobile. In one alternative embodiment, the platform is slidably mounted on the platform frame; in another alternative embodiment, the floor frame, the platform frame, and the platform are size adjustable for accommodating variously sized automobile trunks.
