  • Patent number: 5005325
    Abstract: An open office system partition panel assembly including a panel having an outwardly opening wire raceway channel on top with a removable cap to permit wires to be laid in the top raceway channel. End wire raceway channels open away from the core of the panel and each has a panel connector support rail closing its opening. The wire raceway channels form a steel frame of box section strength for the panel and all metal-enclosed, non-snagging wire raceways from the top to the base of the panel. Legs formed as part of the panel base support the panel connector support rails. Wire passageways extend from the panel base to the end wire raceway channels. The panel base has an end section fastened to and supported on each leg. Upper panel connectors facilitate the connection of panels, improve the rigidity of the connection between panels and provide positive locking for the panel connection, both vertically and horizontally.
