ABSTRACT:
An improved automotive lift device for vehicles which consists of a lift carriage having movable upper step and riser elements so as to selectively form normal upper and lower entrance steps in their retracted normal use position. The upper step and riser pivotally connected thereto are selectively extendable outwardly and downwardly by self-contained actuating device so as to form a continuous horizontal loading platform in association with the fixed lower step formed by the base of the lift carriage. Thus formed, the horizontal loading platform can be selectively lowered to the ground or curb level. It can be also selectively raised to the vehicle interior floor level thereby enabling a handicapped person, on crutches or in a wheelchair, to easily board or disembark from such vehicle at will. The riser element which is pivotally connected to the movable upper step is freely pivotal below the horizontal so as to compensate for uneven ground during the loading operation and can be selectively raised to form a fixed horizontal co-planar extension of the loading platform so as to enlarge the capacity thereof in use. An elongate safety guard plate is pivotally connected to the outer edge of the riser and is normally retracted thereagainst when not in use. When the loading platform is in use, the safety guard plate is selectively moved to a raised vertical position along the outer edge of the riser so as to act as a safety guard to prevent wheelchairs and the like from inadvertently rolling off of the platform.
