ABSTRACT An improved automatic lift device which consists of a lift carriage that is mounted within the doorway opening so as to be vertically movable therein. Movable step and riser elements are provided within the lift carriage so as to form normal upper and lower entrance steps in their retracted normal use position. The lift carriage is selectively movable to a lowered ground level position and a raised interior floor level position while the upper step and riser remain in their retracted normal step position within the lift carriage. The upper step and riser pivotally connected thereto are selectively extendable outwardly and downwardly by self-contained actuating means mounted solely on the base of the lift carriage. Thus actuated, the upper step and riser-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 or to any level intermediate thereto. It can be also selectively raised to the interior vehicle floor level thereby enabling a handicapped person, on crutches or in a wheelchair, to easily board or disembark from such vehicles 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. The riser is then selectively raised to form a fixed horizontal co-planar extension of the loading platform so as to enlarge the capacity of the loading platform during the actual lifting and lowering operation. An elongate safety guard plate is pivotally connected to the outer edge of the riser and is normally retracted thereagainst when not in use. After a wheelchair has been moved onto the loading platform, the safety guard plate can be selectively pivotally moved to a raised vertical position along the outer edge of the riser so as to act as a guard against inadvertent movement of a wheelchair or other equipment from the expanded platform while the platform is being raised to the level of the vehicle inside floor or is being lowered to the ground level. -2-
