Abstract

A retention structure for retaining a recessed lighting fixture behind a ceiling includes an attachment structure that has a first wall and a second wall. The attachment structure is designed to be attached to a housing of a recessed light fixture. The retention structure further includes a screw attached to the first wall of the attachment structure and to the second wall of the attachment structure. The retention structure also includes a pawl attached to the threaded screw. The pawl is rotatable along with the threaded screw. The pawl is also axially movable along the threaded screw between the first wall of the attachment structure and the second wall of the attachment structure.

First claim

What is claimed is:

1 . A lighting structure for a recessed lighting fixture, the lighting structure comprising:
a lighting fixture housing having an opening, the opening including a horizontal slot and a vertical slot, the vertical slot intersecting the horizontal slot; and a retention structure attached to the housing, the retention structure to retain the lighting structure recessed into a ceiling, wherein the retention structure includes:
a wall segment positioned within the housing;
a tension spring segment positioned outside of the housing, the tension spring segment extending out from a first end portion of the wall segment; and
an end segment having a wide segment and a narrow segment, the narrow segment coupled to a second end portion of the wall segment, wherein the wide segment of the end segment is positioned outside of the housing by extending the wide segment of the end segment through the horizontal slot of the opening of the housing, and wherein the narrow segment of the end segment extends through the vertical slot of the opening of the housing.

2 . The lighting structure of claim 1 , wherein the wall segment is positioned against an inner wall of the housing.

3 . The lighting structure of claim 1 , wherein the wide segment of the substantially T-shaped segment is wider than the vertical slot of the opening of the housing.

4 . The lighting structure of claim 1 , wherein the tension spring segment curves down from the first end portion of the wall segment.

5 . The lighting structure of claim 1 , wherein a flange of the tension spring segment rests on the back side of the ceiling below the horizontal slot of the opening of the housing.

6 . The lighting structure of claim 1 , wherein the housing includes a second opening having a second horizontal slot and a second vertical slot and wherein the second vertical slot intersects the second horizontal slot.

7 . The lighting structure of claim 1 , wherein a torsion spring receiver extends out from the wall segment toward a center of the housing.

8 . The lighting structure of claim 1 , wherein the narrow segment of the end segment includes a first vertical segment, a horizontal segment, and a second vertical segment, wherein the first vertical segment extends from the second end portion of the wall segment, wherein the horizontal segment extends between the first vertical segment and the second vertical segment, and wherein the second vertical segment is coupled to the wide segment of the end segment.

9 . The lighting structure of claim 1 , wherein the horizontal slot of the opening of the housing is above the vertical slot of the opening of the housing when the lighting structure is recessed in a ceiling.

10 . A lighting structure for a recessed lighting fixture, the lighting structure comprising:
a lighting fixture housing having an opening, the opening including a horizontal slot and a vertical slot, the vertical slot intersecting the horizontal slot; and a retention structure to retain the lighting structure recessed into a ceiling, wherein the retention structure includes:
a wall segment to be positioned inside the housing;
a tension spring segment extending out from a first end portion of the wall segment, the tension spring segment to be positioned outside of the housing, wherein the tension spring segment is sized to pass through the horizontal slot of the opening of the housing from within the housing; and
an end segment having a wide segment and a narrow segment, the narrow segment coupled to a second end portion of the wall segment, wherein the wide segment of the end segment is to be positioned outside of the housing by passing the wide segment of the end segment through the horizontal slot of the opening of the housing from within the housing, and wherein the narrow segment of the end segment is sized to extend through the vertical slot of the opening of the housing.

11 . The lighting structure of claim 10 , wherein the wall segment is positioned against an inner wall of the housing.

12 . The lighting structure of claim 10 , wherein the wide segment of the substantially T-shaped segment is wider than the vertical slot of the opening of the housing.

13 . The lighting structure of claim 10 , wherein the tension spring segment curves down from the first end portion of the wall segment.

14 . A lighting structure for a recessed lighting fixture, the lighting structure comprising:
a lighting fixture housing; and a junction box attached to a lighting fixture housing, wherein a first portion of the junction box proximal to the housing is vertically narrower than a second portion of the junction box distal from the lighting fixture housing, wherein a proximal end of the junction box is attached to the lighting fixture housing, and wherein the junction box is tapered between a distal end of the junction box and the proximal end of the junction box.

15 . The lighting structure of claim 14 , wherein the junction box includes a first side wall and a second side wall, wherein a bottom edge of the first side wall is slanted angularly upwards as the first side wall extends towards the lighting fixture housing, and wherein a bottom edge of the second side wall is slanted angularly upwards as the second side wall extends towards the lighting fixture housing.

16 . The lighting structure of claim 14 , wherein the junction box includes a bottom wall and a back wall, wherein the bottom wall and the back wall extend between the first side wall and the second side wall, and wherein the back wall is at the distal end of the junction box.

17 . The lighting structure of claim 16 , wherein a cavity of the junction box is accessible via the back wall.

18 . The lighting structure of claim 16 , wherein a first portion of the bottom wall that is proximal to the lighting fixture housing is elevated relative to a second portion of the bottom wall that is distal from the lighting fixture housing.

19 . The lighting structure of claim 14 , wherein the proximal end of the junction box is attached to a housing top of the lighting fixture housing.

20 . The lighting structure of claim 19 , wherein the lighting fixture housing is cylindrical.
