Abstract

A power cord integrated hanger system for suspending a lighting fixture has a flexible load bearing inner suspension part and a flexible non-load bearing outer conductor part that acts as the “power cord” for the suspended lighting fixture. The flexible outer conductor part has an internal passageway for the inner suspension part. An outer cover of the outer conductor part holds electrical conductors in place in the outer conductor part and preferably conceals the conductors from view. The outer cover of the conductor part can be provided with different aesthetic qualities to enhance the visual appearance of the hanger system.

First claim

What we claim is:

1. A power cord integrated hanger system for suspending the feed end of a lighting fixture at a desired suspension height comprising
an elongated and flexible outer conductor part having a flexible elongated inner hollow core providing a center passageway through the flexible outer conductor part, electrical conductors distributed around said inner core, and a flexible elongated outer cover surrounding said electrical conductors wherein the electrical conductors are captured between said inner core and outer cover, and
an elongated and flexible inner suspension part having a first end and second end defining a length, the length of said suspension part being longer than the length of the elongated inner core and the outer cover of said conductor part and being chosen in accordance with the desired suspension height of a lighting fixture to be suspended, said elongated and flexible inner suspension part being insertable through and being sized to slide within the center passageway of said outer conductor part.

2. The hanger system of claim 1 wherein the outer cover of said outer conductor part substantially conceals the electrical conductors of said outer conductor part.

3. The hanger system of claim 1 wherein said outer conductor part has a sufficient length to conceal the inner suspension part over a substantial portion of the length thereof.

4. The hanger system of claim 1 wherein the flexible inner core is fabricated of a durable plastic material.

5. The hanger system of claim 1 wherein the flexible inner core of said outer conductor part is fabricated of a durable plastic material.

6. The hanger system of claim 1 wherein the flexible outer cover of said outer conductor part is fabricated of a PVC plastic.

7. The hanger system of claim 1 wherein the inner core of said outer conductor part is tubular in shape and has an inside diameter, wherein the flexible inner suspension part has a diameter, and wherein the inside diameter of the inner tubular core is greater than the diameter of the suspension part by about 0.0175inches or less.

8. The hanger system of claim 1 wherein said outer conductor part further includes shielding means between the electrical conductors and the outer flexible cover thereof.

9. The hanger system of claim 1 wherein the outer cover of said flexible outer conductor part has defined ends past which the electrical conductors of said outer conductor part extend, and wherein the flexible outer conductor part further includes terminus caps that cap the ends of said outer cover.

10. The hanger system of claim 1 wherein the electrical conductors of said outer conductive part include wire sizes selected from the group consisting of No. 14 gauge wire, No. 16 gauge wire, and No. 18 gauge wire.

11. The hanger system of claim 1 wherein the inner core of said outer conductor part is tubular in shape and has an inside diameter of about 0.080 inches.

12. A power cord integrated hanger system for suspending the feed end of a lighting fixture at a desired suspension height comprising
an elongated and flexible outer conductor part having a flexible elongated inner tubular core having an outside and providing a center passageway through the flexible outer conductor part, electrical conductors running along the outside of said inner core, and a flexible elongated outer cover covering said electrical conductors and inner core, wherein the electrical conductors are captured between said inner core and outer cover, the outer cover of said outer conductor part having defined ends past which the electrical conductors and the flexible inner hollow core extend, and
an elongated and flexible inner suspension cable having a characteristic diameter and having a first end and second end defining a length, the length of said suspension part being longer than the length of elongated inner tubular core and outer cover of said conductor part and being chosen in accordance with the desired suspension height of a lighting fixture to be suspended, and said suspension part being insertable through the center passageway of said outer conductor part,
the flexible inner core of said outer conductor part having an inside dimension that allows the elongated and flexible inner suspension part to closely fit within and slide through the inner core of the outer conductor part when a lighting fixture is installed.

13. The hanger system of claim 12 wherein the inside diameter of the inner tubular core is greater than the diameter of the suspension part by about 0.0175 inches or less.

14. The hanger system of claim 12 wherein the outer cover of said outer conductor part has defined ends past which the electrical conductors extend, and wherein the flexible outer conductor part further includes terminus caps that cap the ends of said outer cover.

15. A power cord part for a power cord integrated hanger system for suspending the feed end of a lighting fixture at a desired suspension height, said power cord part comprising
a flexible elongated inner hollow core providing a center passageway therethrough,
electrical conductors distributed around said inner core, and
a flexible elongated outer cover surrounding said electrical conductors, wherein the electrical conductors are captured between said inner core and outer cover,
said flexible elongated inner hollow core, electrical conductors and flexible outer cover forming a flexible power cord having a center passageway extending through the power cord, said center passageway being sized to slidably receive a flexible suspension cable used to hang the feed end of the lighting fixture, wherein the power cord part covers the suspension cable and the length of the suspension cable is chosen in accordance with the desired suspension height of a lighting fixture to be suspended.

16. The power cord part of claim 15 wherein said flexible inner hollow core has an inside dimension that allows a flexible suspension cable to closely fit within the inner core when a lighting fixture is installed.

17. The power cord part of claim 16 wherein the inside dimension of said flexible inner tubular core is chosen to allow a flexible suspension cable to slide through the center passageway of the tubular inner core.

18. The power cord part of claim 16 wherein the outer cover has defined ends past which the electrical conductors and the flexible inner hollow core extend.

19. The power cord part of claim 18 further comprising terminus caps that cap the ends of said outer cover.

20. The hanger system of claim 15 wherein the flexible inner core of said outer conductor part is fabricated of a nylon plastic material.

21. The hanger system of claim 15 wherein the flexible outer cover of said outer conductor part is fabricated of a PVC plastic.

22. The power cord part of claim 18 further comprising terminus caps that cap the ends of said outer cover.

23. A power cord part for a power cord integrated hanger system for suspending the feed end of a lighting fixture at a desired suspension height, said power cord part comprising
a flexible elongated tubular inner core having an outside and providing a center passageway therethrough, said flexible inner core being fabricated of a durable material,
electrical wires running along said tubular inner core, and
a flexible elongated outer cover covering said electrical conductors wherein the electrical wires are captured between said inner core and outer cover, the outer cover of the power cord
