Abstract

A sconce box assembly for mounting sconces on walls of various wallboard thicknesses and shallow wall cavities with no disruption to the surrounding wall. The sconce box assembly includes an electrical box having a sidewall, a back wall, an electrical cavity, and wing bosses extending from the sidewall. First rotatable wings secured to the wing bosses are adapted for rotation between a retracted position, in which the rotatable wings are positioned inside the sidewall perimeter, and an extended position in which the rotatable wings are positioned outside the sidewall perimeter. Retracting the wings facilitates insertion of the electrical box through a hole in a wall. Extending the wings facilitates tightening the wings and clamping the electrical box to the wallboard. The invention contemplates at least one second rotatable wing that may be used optionally in place of the first rotatable wing in order to accommodate attachment to various thicknesses of wallboards.

First claim

What is claimed is:

1. A sconce box assembly, comprising:
an electrical box including a sidewall and a back wall defining an electrical cavity therein, said back wall including a front surface and a rear surface, and said electrical box including a wing boss having a bore therein;
a first rotatable wing held loosely to said wing boss by a fastener;
said rotatable wing including a front surface, a rear surface, and a stop arm extending from said rear surface; and
two flanges extending from opposing sides of the sidewall.

2. The sconce box assembly of claim 1 , wherein said flanges include rear surfaces that are flush with said rear surface of said back wall of said electrical box.

3. The sconce box assembly of claim 2 , further comprising a fixture boss extending from said front surface of said back wall.

4. The sconce box assembly of claim 3 , further comprising
two of said wing bosses on said electrical box; and
said wing bosses are aligned 180° apart on the sidewall of the electrical box.

5. The sconce box assembly of claim 3 , including
two of said fixture bosses on said electrical box; and
said fixture bosses are aligned 180° apart on the sidewall of the electrical box.

6. The sconce box assembly of claim 1 , comprising a rim on said electrical box, said rim is planar.

7. The sconce box assembly of claim 1 , including an optional second rotatable wing for use in place of said first rotatable wing for attaching said electrical box to a thicker wallboard.

8. The sconce box assembly of claim 1 , wherein said first rotatable wing further comprises a first corner and two opposing corners.

9. The sconce box assembly of claim 1 , wherein said stop arm of said first rotatable wing further comprises a first side and a second side.

10. The sconce box assembly of claim 7 , wherein said second rotatable wing comprises a base portion and an end portion.

11. The sconce box assembly of claim 10 , wherein said end portion of said second rotatable wing is offset a distance from said base portion.

12. A sconce box assembly, comprising:
an electrical box including a sidewall and a back wall defining an electrical cavity therein, said back wall including a front surface and a rear surface, and said electrical box including a wing boss having a bore therein;
a first rotatable wing held loosely to said wing boss by a fastener, said first rotatable wing for mounting said electrical box to a first thickness of wallboard;
a second rotatable wing for optional use in place of said first rotatable wing, said second rotatable wing for mounting said electrical box to a second thickness of wallboard;
said rotatable wings including a front surface, a rear surface, and a stop arm extending from said rear surface; and
two flanges extending from opposing sides of the sidewall.

13. The sconce box assembly of claim 12 , further comprising a fixture boss extending from said front surface of said back wall.

14. The sconce box assembly of claim 13 , wherein said rotatable wings further comprise
a first corner and two opposing corners; and
an aperture in said first corner, said aperture in said first corner enabling rotation of said rotatable wings in a first direction to place said rotatable wings in a retracted position wherein said wings are retracted within said sidewall of said electrical box.

15. The sconce box assembly of claim 12 , wherein said stop arm of said first rotatable wing further comprises a first side and a second side.

16. The sconce box assembly of claim 12 , wherein said second rotatable wing comprises a base portion and an end portion.

17. The sconce box assembly of claim 16 , wherein said end portion of said second rotatable wing is offset a distance from said base portion.

18. A method of securing a sconce to a wall, including
providing a sconce box assembly including an electrical box having a sidewall, a back wall, wing bosses including bores therein on said sidewall, and two flanges extending from opposing sides of said sidewall;
providing a rotatable wing held loosely to said wing boss by a fastener;
rotating said rotatable wing in a first direction until said wing is within the sidewall of the electrical box;
forming a substantially circular hole in the wall;
inserting said electrical box into said hole and pulling said electrical box forward until said flanges seat flush on a rear surface of the wall;
rotating said rotatable wing in a second direction until said wing is outside the sidewall of the electrical box and has drawn said electrical box tight against the wall; and
securing the sconce to the electrical box.

19. The method of claim 18 , which further comprises providing a second rotatable wing for optional use in place of said rotatable wing, said second rotatable wing for mounting said electrical box to a second thickness of wallboard.

20. The method of claim 19 , which further comprises
providing a base portion and an end portion on said second rotatable wing; and
offsetting said end portion of said second rotatable wing a distance from said base portion.
