Abstract
Abstract An elevator storage unit, supporting or containing the articles to be stored, is normally disposed in an above-ceiling enclosure defined by a ceiling opening and overlying enclosure structure. The base platform for the elevator unit defines the closure for the above-ceiling enclosure, in the upper limit position of the unit. The elevator unit is lowered and raised by means of an electric motor powered hoist mechanism, under control of a keyed switch. The elevator unit is lowered for access, and is raised to the above-ceiling position for convenient storage and/or security storage. The elevator unit includes an upper support member from which the base platform is suspended by cables. The support member is suspended by hoist mechanism cables. The elevator unit may function as utility unit for supporting a TV set or a beverage bar in a use condition suspended from the ceiling, but normally stored within the above-ceiling compartment. Corner guides associated with the base platform assure smooth seating within the ceiling opening. The enclosure is readily assembled from prefabricated panels and associated components, and is readily mounted within a ceiling opening.
