Abstract

A wire distribution system for furniture, especially for electric power, communications, and data includes a common feed-in source. In one embodiment, the common feed-in source is a leg assembly adapted to carry the incoming wires. A distribution beam attached to the piece of furniture and defining a trough, carries a distribution harness, which together carry and distribute the power and communications/data wires. Exiting wires from the leg assembly are connected to the distribution harness. The distribution beam has electric receptacles and communications/data jacks, and includes a connectors/plugs to which is attached a connector/plug emanating from the leg assembly carrying the wires. Various pieces of furniture may be coupled together wherein the various distribution beams/harnesses may be coupled together via jumpers.

Claims

1. A system for distributing electrical power, the system comprising:

a piece of furniture including a leg having;

at least one channel; and

at least one fitting in communication with said at least one channel;

at least one conduit, each said conduit being attached to a respective said fitting;

a plurality of electrical power wires routed through each of said at least one channel, said at least one fitting and said at least one conduit, said electrical power wires terminating in a first electrical power connector, said electrical power wires being configured for transmitting the electrical power from a source of electrical power;

a distribution beam having a housing defining an internal cavity, said housing having a cover plate with a plurality of cutouts, and mounting flanges attaching said distribution beam to said piece of furniture;

a distribution harness retained in said internal cavity and having a second electrical power connector coupled with the first electrical power connector, and a third electrical power connector adapted to couple to a fourth electrical power connector; and

a plurality of electrical receptacles accessible through said plurality of cutouts and in communication with said distribution harness to receive the electrical power therefrom.

2. The system for distributing electrical power of claim 1, wherein said distribution harness is retained in said housing so as to define a wire passageway adapted to carry any additional wiring.

3. The system for distributing electrical power of claim 2, wherein said additional wiring is communication/data wiring and said distribution beam includes a communication/data jack coupled to said communication/data wiring.

4. The system for distributing electrical power of claim 2, wherein said distribution harness is riveted to said distribution beam so as to be suspended therein, whereby said wire passageway is defined between an inside surface of said housing of said distribution beam and an outside surface of said distribution harness.

5. The system for distributing electrical power of claim 1, wherein said cover plate is removable.

6. The system for distributing electrical power of claim 1, further comprising a jumper having a fourth connector as said another connector and adapted to couple to and receive electrical power from said third electrical power connector of said distribution harness and having a fifth connector adapted to couple to a first connector of a second distribution harness of a second distribution beam.

7. A system for distributing electrical power to a plurality of tables, the system comprising:

a plurality of distribution systems equal in number to the plurality of tables, each of said distribution systems including a distribution beam having a housing being mounted onto a respective table of said plurality of tables, said housing including a housing portion with a bottom side, said housing also including a removable cover plate having a bottom portion disposed interior of said bottom side of said housing portion, a distribution harness retained in said housing of said distribution beam, said distribution harness including a first electrical power connector disposed at one end thereof and adapted to receive incoming electrical power, a second electrical power connector disposed at another end of said distribution harness, and said distribution beam including an electrical receptacle accessible through said removable cover plate and coupled to receive the electrical power from said distribution harness;

wherein a first one of said distribution systems receives the electrical power from a source of electrical power via electrical wires terminating in a source connector being coupled to said first electrical power connector thereof; and

a plurality of jumpers each having a first jumper connector adapted to couple to the second electrical power connector of a distribution harness, and a second jumper connector adapted to couple to the first electrical power connector of an other said distribution harness.

8. The system for distributing electrical power for a plurality of tables as in claim 7, wherein each said distribution harness is retained in said respective housing so as to define a wire passageway adapted to carry any additional wiring.

9. The system for distributing electrical power for a plurality of tables as in claim 8, wherein each said distribution harness is riveted to each respective said distribution beam so as to be suspended therein, whereby each said wire passageway is defined between an inside surface of each said housing of each said distribution beam and an outside surface of each said distribution harness.

10. The system for distributing electrical power for a plurality of tables as in claim 7, wherein each said cover plate includes a plurality of cutouts and wherein each said distribution system includes a plurality of electrical receptacles accessible through the plurality of cutouts and coupled to a respective said distribution harness.

11. The system for distributing electrical power for a plurality of tables as in claim 7, wherein said bottom side of said housing portion includes a first upwardly flanged lip, said bottom portion of said cover plate including a second upwardly flanged lip configured for allowing said first upwardly flanged lip of said housing portion to be slid under said bottom portion of said cover plate.

12. The system for distributing electrical power for a plurality of tables as in claim 7, wherein said housing portion includes at least one substantially horizontal flange configured for engaging an underside of the respective table and receiving at least one fastening device for mounting said distribution beam to the underside of the respective table.
