Abstract: A vehicle parking structure particularly well adapted for providing a parking capacity of up to about 20 vehicles has a structure framework with an entrance/exit level and a plurality of parking level floors, each of the floors having a pair of parking bays located on opposite sides of an elevator shaft. Vehicles to be parked are driven onto a vehicle tray, which is raised and lowered by means of an elevator in the elevator shaft. The elevator includes a shifter on which the tray is supported which allows the tray to be cantilevered outwardly from the elevator at a parking level. With the tray so cantilevered outwardly, the tray is incrementally lowered to rest on a pair of tray supports in the desired parking bay. The shifter is then retracted and the elevator can be raised or lowered to another level as required. To retrieve a vehicle, the elevator and shifter is positioned incrementally below the identified tray, and the shifter is extended into the bay.

Abstract: An improved automated parking garage structure comprising a supporting framework bearing a plurality of vehicle parking stalls arranged in a radial manner on a plurality of levels about a central core. Each of the stalls support a vehicle on a series of fingers. An elevator tower is located within said central core and has an elevator platform adapted for vertical travel, the tower rotating about a vertical axis. A transfer lift for transferring a vehicle between ground level and a level for transfer to or from said elevator platform; is located at ground level and accepts vehicles for parking and return. The elevator platform includes an extension carriage for transferring a vehicle between the platform and the stalls and transfer lift. Operation of the transfer lift, elevator and tower are coordinated by an automated control system, which may include a first unit located at the tower and a second unit, serving as a customer interface, at a remote location.
