Abstract

A modular furniture system is provided having vertical members with internal conductors. The conductors are coupled to a source of low voltage electrical power such that adjacent vertical members are of differing electrical polarity. Support members for use in the modular furniture system are designed to make electrical contact with the internal conductors when engaged in a vertical member. An electrical device, such as a light fixture, may be coupled between a pair of brackets engaged in vertical members of opposite polarity, energizing the electrical device. Embodiments are provided for use in merchandising displays and office partition systems.

Claims

1. A modular furniture system comprising:

a first vertical member comprising;

a first outer member having a first opening in a face thereof; and

a first conductive member disposed behind the first outer member such that a portion of the first conductive member is disposed near the first opening, the first conductive member being adapted to be coupled to a source of electrical power; and

a first support member comprising a conductive material, the first support member including;

a shank portion for engaging the first opening; and

a contact portion for making electrical contact with the first conductive member.

2. The modular furniture system of claim 1 further comprising:

a second vertical member, comprising;

a second outer member having a second opening in a face thereof; and

a second conductive member disposed behind a second outer member such that a portion of the second conductive member is disposed near the second opening, the second conductive member being adapted to be coupled to the source of electrical power,

wherein the first and second vertical members are juxtaposed in a spaced apart, substantially parallel relation, and wherein the second conductive member is adapted to be coupled to a source of electrical power.

3. The modular furniture system of claim 2 further comprising a power source coupled to the first and second conductive members such that they are of opposite polarity.

4. The modular furniture system of claim 3 wherein the power source is a low voltage power source.

5. The modular furniture system of claim 2 further comprising a horizontal member disposed between the first and second vertical members, the horizontal member comprising:

first and second ends adapted to couple to the first and second conductive members; and

at least one electrical fixture coupled between the first and second ends, such that the at least one electrical fixture is electrically coupled to the first and second conductive members.

6. The modular furniture system of claim 2 further comprising a panel coupled between the first and second vertical members.

7. The modular furniture system of claim 6 wherein the panel includes at least one electrical fixture, the panel being electrically coupled to the first and second conductive members such that the electrical fixture receives power therefrom.

8. The modular furniture system of claim 7 wherein the panel has a translucent surface and the at least one electrical fixture is a light disposed behind the translucent surface.

9. The modular furniture system of claim 5 or 7 wherein the at least one electrical fixture comprises a socket.

10. The modular furniture system of claim 9 further comprising an electrical device including a plug for mating with the socket such that the electrical device receives electrical power via the socket.

11. The modular furniture system of claim 10 wherein the electrical device comprises a light.

12. The modular furniture system of claim 1 wherein the vertical member further comprises:

a second opening in the face of the first outer member, such that the second opening is substantially level with, but spaced apart from, the first opening; and

a second conductive member disposed behind the face of the first outer member such that a portion of the second conductive member is disposed near the second opening, wherein the second conductive member is adapted to be coupled to a source of electrical power having a polarity opposite that of the first conductive member.

13. The modular furniture system of claim 2 or 12 further comprising a second support member comprising a conductive material, the second support member including:

a shank portion for engaging the second opening; and

a contact portion for making electrical contact with the second conductive member.

14. The modular furniture system of claims 13 further comprising a furniture piece coupled between the first and second support members.

15. The modular furniture system of claim 14 wherein the furniture piece comprises a shelf, desk, clothes rod, or display case.

16. The modular furniture system of claim 14 wherein the furniture piece comprises a light, the light being electrically coupled to the first and second support members.

17. The modular furniture system of claim 16 wherein the light is disposed on the underside of a shelf, or inside a desk.
