Abstract

Invalid lift apparatus particularly adapted for installation in an automotive vehicle of the van type characterized by a passenger side door adjoining a loading floor. The apparatus includes a storage receptacle mountable below the loading floor to receive a platform for wheelchair passengers. The platform is extensible onto movable supports for raising and lowering relative to fixed supports attachable at opposite sides of the door opening. Limit switches are provided to control the extent of upward and downward movement of the platform, and to orient the platform in proper position for movement out of the way and onto the storage receptacle whereby ambulatory passengers can enter and leave the vehicle.
