Abstract

Tenon-mounted lighting fixtures with high structural integrity are provided. In one embodiment, the lighting fixture has a housing that has an integrally formed tenon cradle, which is configured to receive a tenon of a light pole. A light source is also mounted on a bottom side of the housing. The tenon cradle is between a first bolt boss and a second bolt boss, and is in communication with a rear opening of the housing. The first and second bolt bosses may be integrally formed in the housing. The tenon cradle includes multiple ribs. An arcuate cross rib resides in a first plane in which a first bolt shaft of the first bolt boss and a second bolt shaft of the second bolt shaft reside. An axial rib intersects the arcuate cross rib and runs perpendicular to the first plane.

First claim

What is claimed is:

1. An outdoor lighting fixture comprising:
a light source;
a housing comprising a receiving region in communication with a rear opening of the housing and configured to receive a tenon of a light pole; and
a cradle assembly attached to the receiving region of the housing, the cradle assembly comprising a cradle body with a stepped structure forming a plurality of platforms configured to receive an end of the tenon of the light pole at a selected one of a plurality of different levels.

2. The outdoor lighting fixture of claim 1 , wherein the cradle body further comprises tenon supports at an end of the cradle body.

3. The outdoor lighting fixture of claim 1 , wherein the plurality of platforms are beveled inward within the cradle body.

4. The outdoor lighting fixture of claim 1 , wherein the cradle assembly further comprises a cross bracket that is positioned between the cradle body and the receiving region of the housing.

5. The outdoor lighting fixture of claim 4 , wherein the cradle assembly is attached to the receiving region of the housing such that the cross bracket is held in place.

6. The outdoor lighting fixture of claim 4 , further comprising a cradle bracket that is fixed to the cross bracket such that the tenon is positioned between the cradle bracket and the cross bracket.

7. The outdoor lighting fixture of claim 6 , wherein the cradle bracket comprises a first wing, a second wing, and a tenon interface between the first wing and the second wing, the tenon interface configured to engage the tenon when the tenon is within the cradle assembly.

8. The outdoor lighting fixture of claim 7 , wherein the cradle bracket is bolted to the cross bracket by a first bolt that extends through the first wing and a second bolt that extends through the second wing.

9. The outdoor lighting fixture of claim 8 , wherein the cross bracket is configured to bend about the tenon.

10. The outdoor lighting fixture of claim 8 , wherein the housing forms one or more turrets configured to receive the first bolt and the second bolt.

11. The outdoor lighting fixture of claim 7 , wherein the cradle bracket further comprises opposing sidewalls such that the first wing and the second wing reside between the opposing sidewalls, and the tenon interface is provided by arcuate recesses in a bottom of the opposing sidewalls.

12. The outdoor lighting fixture of claim 11 , wherein the tenon interface is concave at the bottom of the opposing sidewalls.

13. The outdoor lighting fixture of claim 7 , wherein the tenon interface comprises a gripping surface.

14. The outdoor lighting fixture of claim 7 , wherein the tenon interface comprises at least one of teeth or splines.

15. A cradle assembly for a lighting fixture, the cradle assembly comprising:
a cradle body comprising a stepped structure forming a plurality of platforms configured to receive an end of a tenon at a selected one of a plurality of different levels; and
a cross bracket that is configured to receive one or more bolts to secure the tenon to the cradle body.

16. The cradle assembly of claim 15 , wherein the cradle body further comprises tenon supports.

17. The cradle assembly of claim 16 , wherein the tenon supports are arranged on an opposite end of the cradle body than the stepped structure.

18. The cradle assembly of claim 15 , wherein the plurality of platforms are beveled inward within the cradle body.

19. The cradle assembly of claim 15 , wherein the cross bracket is further configured to bend about the tenon.

20. The cradle assembly of claim 15 , wherein the cross bracket forms a U-shape about portions of the cradle body.
