Abstract

An electrical box and frame assembly for mounting an electrical component such as a duplex receptacle in a shallow wall cavity. The electrical box assembly includes a box member, a receptacle frame adapted to receive an electrical component, and a trim plate. Rotatable flags on the box member provide ease of installation to a wall in old or new work situations. The box member includes sidewalls of a narrow depth to enable mounting within a shallow wall cavity. The receptacle frame nests substantially within the cavity of the box member and the trim plate secures over the receptacle frame and is mounted to the box member. An outer sidewall on the receptacle frame includes bosses thereon for securing a duplex receptacle in a sideways orientation with respect to the box member and wall cavity thereby enabling the electrical box and frame assembly to be mounted in a shallow wall cavity.

Claims (47)

1. An electrical box and frame assembly comprising:

a box member including two pairs of opposing sidewalls and a back wall forming a cavity therein, said sidewalls including a front edge;

a divider plate integral with and extending from said back wall of said box member, said divider plate extending between one of said pairs of opposing sidewalls of said box member, said divider plate including a notch therein;

a receptacle frame adapted for attachment to said box member, said receptacle frame including integral bosses adapted for the mounting of an electrical component thereto such that said electrical component is mounted orthogonal with respect to said front edge of said box member, said receptacle frame including a sidewall with a notch therein;

connection of said receptacle frame to said box member aligning said notch in said receptacle frame with said notch in said divider plate thereby forming an electrical box face with an opening therein for receipt of said electrical component; and

a trim plate extending from said front edge of said box member, said trim plate effecting a flush fit of said box member against the wall.

2. The electrical box and frame assembly of claim 1 including

a flange on said trim plate;

a peripheral flange on said box member; and

said box member including a depth measured from said front edge of said box member to said rear surface of said back wall of no more than 1.25 inches.

3. The electrical box and frame assembly of claim 2 including a mounting arrangement for securing said box member to said wall.

4. The electrical box and frame assembly of claim 3 wherein said mounting arrangement includes

apertures in said flange of said trim plate;

apertures in said peripheral flange of said box member;

mounting fasteners including distal ends, said mounting fasteners extending through said apertures in said flange of said trim plate and through said apertures in said peripheral flange of said box member; and

rotatable flags attached to said distal end of said mounting fasteners.

5. The electrical box and frame assembly of claim 1 wherein said box member includes

a slanted mounting surface; and

a knockout in said slanted mounting surface.

6. The electrical box and frame assembly of claim 5 including a cable connector in said knockout of said slanted mounting surface.

7. The electrical box and frame assembly of claim 5 wherein said slanted mounting surface is at an angle of from 40 to 60 degrees with respect to said sidewalls of said box member.

8. The electrical box and frame assembly of claim 1 wherein

said receptacle frame includes a short sidewall and three long sidewalls; and

a mating edge on said short sidewall of said receptacle frame.

9. The electrical box and frame assembly of claim 8 including

a peripheral edge on said long sidewalls of said receptacle frame;

bores extending through said receptacle frame; and

collars surrounding said bores, said collars including edges flush with said peripheral edge of said receptacle frame.

10. The electrical box and frame assembly of claim 8 wherein said divider plate includes a front edge, said front edge of said divider plate mating with said mating edge of said receptacle frame and said long sidewalls of said receptacle frame mating with said back wall of said box member to form an electrical box within said box member when said receptacle frame is secured to said box member.

11. The electrical box and frame assembly of claim 10 wherein said front edge of said divider plate joins said mating edge of said receptacle frame to form a parting line between said divider plate and said receptacle frame.

12. The electrical box and frame assembly of claim 1 wherein said electrical box face is orthogonal to said back wall of said box member and said electrical box face faces said sidewalls of said box member.

13. The electrical box and frame assembly of claim 1 wherein said electrical component is a duplex receptacle.

14. The electrical box and frame assembly of claim 1 wherein said electrical component is a cord grip mount and a cord grip fitting.

15. The electrical box and frame assembly of claim 1 wherein said sidewalls of said box member include one or more cable openings therein.

16. The electrical box and frame assembly of claim 15 wherein said back wall of said box member includes a cable tie-off clip.

17. The electrical box and frame assembly of claim 1 including

a fastening arrangement for securing said box member to a substrate;

said fastening arrangement including an aperture in said back wall of said box member; and

a collar around each aperture.

18. The electrical box and frame assembly of claim 1 wherein

said trim plate includes a flange having a rear side and a peripheral wall extending from said rear side of said flange; and

said peripheral wall of said trim plate nests within said sidewalls of said box member when said trim plate and said box member are secured together.

19. The electrical box and frame assembly of claim 1 including

two of said electrical box and frame assemblies used in conjunction to reverse feed power from a first electrical box and frame assembly to a second electrical box and frame assembly;

said first electrical box and frame assembly including a cord grip mount, a cord grip fitting, and an electrical cord including an end secured to said electrical box and frame assembly by said cord grip fitting and a plug end for connection to an electrical outlet; and

a second electrical box and frame assembly including a duplex receptacle secured to said receptacle frame,

whereby power is supplied from said electrical outlet through said electrical cord and to said first electrical box and frame assembly and thence to said duplex receptacle of said second electrical box and frame assembly.
