Abstract

A niche for a pool or spa light includes a back wall having an aperture for a power cable, a side wall, a plurality of mounting ribs, and means for receiving a locking mechanism of a pool or a spa light for locking the pool or spa light in position with respect to the niche. In another embodiment, a niche for a pool or spa light includes a body and a rotatable hub with a plurality of mounting ribs for attaching a pool or spa light to the hub. The body includes a back wall having a power cable aperture and a threaded aperture for receiving a screw, and a side wall. The hub includes a back wall having an aperture for receiving the screw and a plurality of mounting ribs, the hub being rotatable about the screw.

First claim

What is claimed is:

1. A pool or spa light niche, comprising:
a back wall including an aperture for receiving a power cable of a pool or a spa light;
a side wall attached at one end about the periphery of the back wall;
a plurality of mounting ribs attached to an inner surface of the side wall; and
means formed in at least one of the plurality of mounting ribs for receiving a locking mechanism of the pool or spa light, the locking mechanism rotationally engaging said means for receiving the locking mechanism in order to lock the pool or spa light in position with respect to the niche.

2. The pool or spa light niche of claim 1 , further comprising an electrically non-conductive conduit hub attached to an exterior of the back wall adjacent the aperture.

3. The pool or spa light niche of claim 2 , wherein the conduit hub is angled at 45° relative to the back wall of the niche.

4. The pool or spa light niche of claim 3 , further comprising a 45° bend elbow conduit connected to the conduit hub for providing a full 90° bend exiting the niche.

5. The pool or spa light niche of claim 1 , further comprising four mounting ribs attached to an inner surface of the side wall, and a groove formed in each of the four mounting ribs for receiving the locking mechanism of the pool or spa light, for locking the pool or spa light in position with respect to the niche.

6. The pool or spa light niche of claim 1 , wherein the niche is formed entirely of electrically non-conductive material.

7. The pool or spa light niche of claim 1 , wherein the niche is formed entirely of non-metallic material.

8. The pool or spa light niche of claim 1 , further comprising the pool or spa light including the locking mechanism configured to engage the plurality of mounting ribs.

9. The pool or spa light niche of claim 8 , wherein the locking mechanism comprises:
an engagement head;
a body connected to the light;
a stopper configured to engage the plurality of mounting ribs; and
a flexible arm including a first end connected to the body and a second end connected to the engagement head,
wherein the engagement head is configured to contact the plurality of mounting ribs and flex the flexible arm such that the engagement head can pass across said means for receiving the locking mechanism and releasably engage the mounting rib.

10. The pool or spa light niche of claim 9 , wherein the light further comprises an aperture configured to allow insertion of a pin to disengage the engagement head from the mounting rib.

11. The pool or spa light niche of claim 10 , wherein the light is not removable from the niche without utilizing the pin.

12. The pool or spa light niche of claim 10 , further comprising a trim ring on said light for covering said aperture of said light.

13. A pool or spa light niche, comprising:
a body including a back wall having an aperture for receiving a power cable and a threaded aperture for receiving a screw, and a side wall attached at one end about the periphery of the back wall;
a hub including a back wall having an aperture for receiving the screw and a plurality of mounting ribs attached to the back wall, the hub being rotatable about the screw; and
means formed in at least one of the plurality of mounting ribs for receiving a locking mechanism of a pool or a spa light, the locking mechanism rotationally engaging said means for receiving the locking mechanism in order to lock the pool or spa light in position with respect to the niche,
wherein the screw is insertable through the aperture of the hub and received by the threaded aperture of the body to secure the hub to the body.

14. The pool or spa light niche of claim 13 , further comprising an electrically non-conductive conduit hub attached to an exterior of the back wall adjacent the aperture.

15. The pool or spa light niche of claim 14 , wherein the conduit hub is positioned at a 45° angle relative to the back wall of the niche.

16. The pool or spa light niche of claim 15 , further comprising a 45° bend elbow conduit connected to the conduit hub for providing a full 90° bend exiting the niche.

17. The pool or spa light niche of claim 13 , further comprising four mounting ribs attached to an inner surface of the back wall of the hub and a groove formed in each of the four mounting ribs for receiving the locking mechanism of the pool or spa light, for locking the pool or spa light in position with respect to the niche.

18. The pool or spa light niche of claim 13 , wherein the niche is formed entirely of electrically non-conductive material.

19. The pool or spa light niche of claim 13 , wherein the niche is formed entirely of non-metallic material.

20. The pool or spa light niche of claim 13 , further comprising a light including the locking mechanism configured to engage the plurality of mounting ribs.

21. The pool or spa light niche of claim 20 , wherein the locking mechanism comprises:
an engagement head;
a body connected to the light;
a stopper configured to engage the plurality of mounting ribs; and
a flexible arm including a first end connected to the body and a second end connected to the engagement head,
wherein the engagement head is configured to contact the plurality of mounting ribs and flex the flexible arm such that the engagement head can pass across said means for receiving the locking mechanism and releasably engage the mounting rib.

22. The pool or spa light niche of claim 21 , wherein the light further comprises an aperture configured to allow insertion of a pin to disengage the engagement head from the mounting rib.

23. The pool or spa light niche of claim 13 , further comprising a rotation index provided on the back wall of the body and a window provided through the back wall of the hub, wherein at least a portion of the rotation index is viewable through the window when the hub is attached to the body.
