1. Technical Field
The present invention generally relates to a conduit and, more particularly, a conduit that accommodates and covers clamps. Specifically, the present invention relates to a cover or conduit that is configured to receive a clamp that holds lengths of wires or tubing.
2. Background Information
When a central air conditioning unit is added to an older house, the line set for the heat exchanger may have to be installed across a finished basement room. Ideally, the line set can be hidden above a ceiling or behind a piece of molding. In some situations, hiding the line set is impossible and the homeowner will have the line set extending across the top of a wall in a finished room in a basement. The homeowner and contractor desire to have a cover member or conduit that can aesthetically hide the line set. The same problem is encountered during home networking when computer wires extend from room to room or place to place. Home theaters also require wire runs for the surround sound speakers. All of these applications create the problem of unsightly wires.
The present invention provides a cover that may be used to aesthetically cover lengths of tubing or wire such as line sets. The cover accommodates clamps that hold the tubes or wires within the cover. The cover includes first and second halves that cooperate together to surround the clamps. The halves have identical cross sections so that they may be fabricated from a single mold. In one embodiment, the invention provides cover halves that snap together. In another embodiment, a fastener is used to hold the halves together.
In one embodiment, the invention provides a clamp covers that holds the clamps within the cover by the feet of the clamps. The feet are frictionally held in oppositely facing slots formed in opposed corners of the cover. The invention also provides a method of installing the clamps. The clamps are installed by angling the clamps with respect to the longitudinal axis of the cover and pressing the clamp against the base wall of the cover. The clamp is then twisted to a position substantially perpendicular to the longitudinal axis of the cover. The twisting motion simultaneously moves the feet of the clamp under the locking ledges of the clamp cover.

A wall 2 of a typical room is depicted in FIG. 1. The ceiling 4 is depicted in section with each of the floor joists 6 running perpendicular to the direction of cover 10 of the present invention. In the room depicted in
Cover 10 is configured to accommodate the prior art clamps 12 that are commonly used to hold tubing or wiring. Prior art clamp 12 is depicted in FIG. 2 and is disclosed in U.S. Pat. No. 6,079,674, the disclosures of which are incorporated herein by reference to disclose all of the elements and the function of clamp 12. Clamp 12 includes opposed feet 14 that are used to mount clamp 12 to a support. Feet 14 are also used to mount clamp 12 to cover 10.
Cover 10 includes a first half 20 (
In the embodiment of the invention wherein each half 20 and 22 has identical cross sections, each half 20 and 22 includes a base wall 24 and a sidewall 26. Base wall 24 and sidewall 26 are substantially perpendicular to one another and are joined at a corner 28. At the end of base wall 24 opposite corner 28, a first flange 30 extends substantially perpendicularly from base wall 24 in the same direction as sidewall 26. The junction between flange 30 and base wall 24 is referred to as a second corner 32. A first clamp locking ledge 34 extends out from first flange 30 in a direction substantially parallel to base wall 24 to form a locking slot. First clamp locking ledge 34 is spaced above the upper surface of base wall 24 a distance slightly larger than the thickness of foot 14 so that foot 14 of clamp 12 may slide below first clamp locking ledge 34. The arrangement may provide for a frictional fit between foot 14 and ledge 34. A second clamp locking ledge 36 projects outwardly from sidewall 26 adjacent corner 28. Second clamp locking ledge 36 is substantially parallel to base wall 24 and spaced from base wall 24 similar to first clamp locking ledge 34. This forms another locking slot. The width of first clamp locking ledge 34 is greater than the width of second clamp locking ledge 36.
A locking channel 40 extends out from sidewall 26 at the end of sidewall 26 opposite corner 28. Locking channel 40 includes first 42, second 44, and third 46 walls that are configured to cooperate with flange 30 and first clamp locking ledge 34 to lock halves 20 and 22 together. As such, wall 42 has a height sufficient to space second wall 44 from sidewall 26 a distance to receive the projecting portion of first flange 30 that projects above first clamp locking ledge 34. This configuration may be seen in
Clamp 12 is positioned in one of halves 20 or 24 as depicted in
