ABSTRACT:
A vehicle-mounted device for use in moving a wheelchair and its occupant to and from the bed of a vehicle, comprising a platform for supporting the wheelchair, two parallelogram linkages having base links secured in place in the vehicle and end links carried by elongated arms swinging in space vertical planes, [and means securing the platform] the platform being secured to the end links for movement in a generally horizontal attitude along an arcuate path so that one edge of the platform passes close to the edge of the bed of the vehicle at the access opening, and engages a stop in the vehicle for folding the platform into a storage position as the linkages complete their arcs. A motorized chain-and-sprocket drive swings the linkages between lowered, outwardly extending positions and raised, upright storage positions in the vehicle, and controls are provided for operating the drive and stopping the platform in an intermediate, entry position level with the bed. A first embodiment has the base and end links horizontal, the platform carried on upright posts, and a second embodiment has the end and base links upright.
