Abstract: A lifting apparatus for a vehicle, which comprises: a platform adapted to be fitted into a cut portion formed at the backward portion of the floor of a vehicle; a drive element provided at support members attached to the lower part of the floor; a drive shaft axially supported by the support members so that it rotates by expanding or contracting movement of a working rod of the drive element; an L-shaped drive arm having an elbow portion fixed to the drive shaft, a short rod portion, and a long rod portion pivotally supported by the platform; an L-shaped driven arm provided oppositely to the drive arm and having a long rod portion similarly pivotally supported by the platform, an elbow portion pivotally supported by the support member, and a short rod portion; and a connecting rod having both end portions respectively pivotally supported by the short rod portions of the driven arm and the drive arm, and adapted for transmitting a drive force of the drive element.

Abstract: An elevator device insertable into and transportable in a motor vehicle for lifting and lowering heavy loads comprises a base plate, a main frame and an additional frame, and an elevating arrangement positioned between said frames. The elevating arrangement is foldable to vertically stand and lean against the main frame while in non-use position, and unfoldable to lie horizontally on a connecting shaft in a stable use position. Each frame is provided with a parallelogram link mechanism and the elevator arrangement is provided with a pressure air cylinder-piston unit operated to compensate for the weight of the elevator arrangement to enable one to easily place the arrangement to one of said positions.
