Abstract
A vehicular wheelchair step lift for persons who are physically challenged or otherwise have limited mobility. The lift includes a platform structure which is mounted to an elevator frame which is then mounted to an elevator housing for vertical movements of the platform structure. The platform structure includes a plurality of individual plates which are rotatably connected at their transverse adjacent edges for manually folding and unfolding the platform, wherein the individual plates are manually folded from an outermost individual plate against an adjacent individual plate to an innermost individual plate for stowing the platform structure into a step position of the vehicle and manually unfolded inversely such that the individual plates are substantially horizontal and in fully coplanar alignment to each other for use in an entry level position. A roll-stop plate is rotatably connected to a free edge of the outermost plate such that the roll-stop plate is manually folded for stowing, manually unfolded for use and manually raised to a vertical position for preventing a wheelchair from rolling-off the platform structure before the platform structure reaches a ground level position.
