Abstract: A lift assembly is provided which can be mechanically converted from a stationary step-like configuration to a movable platform configuration, thus allowing both handicapped and non-handicapped passengers to use a single vehicle entrance having the lift assembly operative within it.A pair of lifting columns are provided which are movable along guide members mounted at the entrance of the vehicle. A platform is hingably connected at its inner edge to the bases of the lifting columns and comprises a linear assembly of hinged plates. Radius arms, pivotally connected with the outer edge portion of the platform and with the lifting columns, suspend the outer end of the platform.

Abstract: A platform is mounted in the doorway of a van so that it can be rotated from an upstanding stored position to a horizontal loading position level with the vehicle floor. From this point, it can be lowered to the ground. A particular linkage and cable-and-drum combination is disclosed which is very compact in the stored position. The unit is fully automated in that: (1)a switch, internal of the vehicle, can be actuated to mechanically open the vehicle doors and rotate the platform from the storage to the loading position or vice-versa; (2)a switch, accessible from the platform, can be actuated to lower or raise the platform between the loading and ground positions; and (3)a switch, external of the vehicle, can be actuated to open the doors and move the platform from the stored to the ground positions or vice-versa.
