ABSTRACT:
A retractable power center (100) for providing conveniently located electrical power source receptacles (170) is adapted to be mounted in a work surface (104) such as a desk top or similar article of furniture. The power center (100) is manually operable and includes a stationary upper housing (108) received within a slot (102) formed in the work surface, and a clamping arrangement (118, 128, 138) to secure the housing (108) to the work surface (104). In addition, a manually movable and slideable power carriage (150) is utilized to mount the receptacles (170). In response to manually exerted forces on the power carriage (150), the carriage can be extended upward into an open position. Relatively small bosses (180) extend laterally from lateral sides of the carriage (150) and provide a means to support the carriage (150) in its extended position, with the bosses (180) resting on the top portion of the housing (108). Still further, ledges (182) are integrally formed on the lateral sides of the carriage (150) near the bottom portions thereof, so as to prevent any further additional movement of the carriage (150) upwardly relative to the housing (108).
