Abstract: An access floor panel includes a generally rectangular pan having a bottom and sides. The pan includes peripheral flanges which define downwardly opening channels or grooves extending around the edge or periphery of the panel. A plurality of elongated, vinyl trim pieces are slidably positioned on the peripheral flanges and disposed within the downwardly opening channels. Each of the trim pieces includes a generally L-shaped slot dimensioned to receive the peripheral flange.

Abstract: An access floor panel includes a metal pan having a bottom and sidewalls. Lanced tabs extend from the bottom. A plurality of corner inserts include pad portions and core portions extending through the bottom. A concrete mixture encapsulates the tabs and insert core portions. The inserts cooperate with pedestal heads or plates to lock the panel to support pedestals. The panels also include silencer buttons. The buttons and inserts limit metal-to-metal contact. The inserts eliminate the need for stringers.

Abstract: A power distribution system for an open office, space dividing, wall panel system wherein electrical power is transferred from one space dividing wall panel to another through a connecting post cap. Each panel includes a terminal block at each upper corner having an outwardly projecting, arcuate contact carrying tongue, which arcuate contacts may be electrically connected to the arcuate contacts of an adjacent panel through complementary ring contacts on the underside of a cylindrical connecting cap.

Abstract: A combination space dividing wall panel and fluorescent lighting fixture wherein the fluorescent lighting fixture is mounted a predetermined distance above the upper edge of the wall panel by a pair of lighting fixture support posts having inverted U-shaped saddle-like members overlying the upper horizontal edge of the wall panel. The support posts extend into threaded apertures in the underside of the lighting fixture and are variably rotatably positionable therein to provide for either linear alignment of the U-shaped saddle members or an angular relationship therebetween to accommodate interconnected angularly related wall panels as the lighting fixture base support.
