Abstract
An apparatus for lowering and raising a handicapped person from a vehicle. A post is fixedly mounted within the vehicle having a top end pivotally supporting a channel. A member is slidably and telescopically mounted to the channel with a platform pivotally mounted to the bottom end of the member. A screw extends through the channel being threadedly engaged with the member and drivingly rotated by a sprocket and chain combination in turn driven by a motor. Rotation of the screw results in the extension and retraction of the member. A bridge is pivotally mounted in the vehicle and may be swung outwardly forcing the platform outwardly of the truck. The bridge allows for a wheelchair to be moved from the vehicle across the bridge and to the platform which is then lowered. In a second embodiment, the platform is supported by a second member telescopicially mounted to a second channel in turn pivotally mounted to a second post mounted within the vehicle and aligned with the first post.
