Abstract: A dual function door acts as both a pocket door and a hinged swinging door. A first door panel is hingedly attached to a wall for swinging. A first header rail is attached to the top of the first door panel while a second header rail is attached to an appropriate surface at the same height as the first header rail. A second door panel has rollers that slide within the first header rail. The first door panel is positionable so that the first header rail and the second header rail align allowing the second door panel to also slide within the second header rail. The two header rails can be locked in the aligned position.

Abstract: A lifting system for lifting and lower people between a vehicle door and ground level uses a carriage that is slid underneath and out from the undercarriage of the vehicle. A lift platform is flush with the carriage when stowed and is capable of being raised from this position up to the door and lowered down to the ground. A series of housing are located on the underside of the carriage and have a sprocket gear thereon. Extension arms are attached to each gear and rotatably to a lift platform. Rack gears mesh with the sprocket gears for rotating the arms and thus the platform up and down, the rack gears articulated via one or more hydraulic drives, with rotation of the arms resulting in articulation of the platform.
