ABSTRACT:
A lift is provided characterized by its ability to be simply retrofitted into a van or similar vehicle of virtually any style construction without requiring the modification of the existing structure. The unit comes in a small, neat package which is hinged on a vertical axis to a door post adjacent the hinge of one of the doors. The mounting plate of the unit which mounts the hinge also mounts a slide in its distal end which slides in a track in the door, so that as the door is opened the mounting plate is supported at one end by its hinge and at the other end in the slide. A horizontal carrier slides outwardly on tracks on the mounting plate, so that the unit clears the vehicle structure, and then a vertical carrier descends from the horizontal carrier by virtue of a hydraulic actuator. A folding platform then swings down on its horizontal hinge along the lower edge of the vertical carrier, and the various extensions and safety flaps necessary for proper operation are then deployed from within the platform structure. In its deployed mode, the platform is vertically moved on the vertical carrier, and is subsequently stowed by drawing the collateral structure into the platform, swinging the platform from its horizontal position up vertically against the horizontal and vertical carriers, with the carrier being telescoped so that all three units define a small package which can slide inwardly on the mounting plate permitting the door to close, so that the entire lift package, when not deployed, is neatly stowed in a relatively small space in the interior of the van.
