Abstract

An interlock system for use in an array of retractable storage cradles. The instant system prevents the opening of more than one cradle at one time through a slide modified generally by a biased cam insertion-extraction means and a column of movable components. The system can be used in free-standing file cabinets as well as prefabricated and modular storage units.
