Description
UNIVERSAL SUPPORT BRACXET FOR AN
ELECTRICAL B~X
The present invention relates to a bracket for supporting an electrical box in a hollow wall structure.
More specifically the present invention provides a bracket that can be adapted to hold electrical boxes of most standard sizes and fit either flush or recessed within hollow wall structures of different depths.
Most interior non-combustible wall structures are hollow and consist of a steel stud skeleton with wall board coverings. The steel studs are made of khin sheet metal which by itself is flexible, however, when the studs are attached to the stiff wall boards then the rigidity of the wall is achieved.
Electrical boxes for outlets, switches and the like, are attached to the steel studs directly or by means of brackets. In either case, the boxes require some additional means of support from the wall boards to achieve rigid mounting. In the past, this has been achieved by attaching additional supports to the box at the side opposite from the stud. In some cases, short pieces o~ steel studs or wood are attached by screws to the box and to the wall board. This method offers good support, but is relatively expensive as the parts are usually prepared at the job site and are time consuming to assemble in place.
It is an aim of the present invention to provide a universal support bracket that attaches to an electrical box and holds it rigidly within the wall structure. The bracket can position the electrical box either ~lush with the outside surface of the wall or recessed from the outside surfac~ of the wall~ The box is generally supported against the steel stud~
It is another aim of the invention to provide a universal support bracket that can be adapted to fit most sizes of electrical boxes and can also ~e adapted to fit ~ithin different depths of hollow wall structure.

One embodiment of a universal support bracket 10 is shown in FIGS 1 & 2. The bracket 10 is preferably formed from sheet metal and has a flat elongate strip 12 which at one end has a pair of hooks 16 which fit over an open side of an electrical box. The hooks 16 are to hold the box. An arm 18 is positioned between the two hooks 16 with grooves 2n dividing the arm 18 from the hooks 16. At the end of the arm 18 is a first flange 22 which extends perpendicular from the flat elsngate strip 12~
The first flange 22 is used for positioning the bracket 10 when the electrical box 17 is recessed and flush mounted to the inside surface of a front wall board as shown i~ FIGS 3 to 5.
A bend line 24 is placed at the top of the arm 1~ 18 at the termination of the grooves 20. The bend line 24 may include an opening in its approximate center so that the arm may be bent by pliers or some other tool across the bend line 24. When the arm 18 is bent up as shown in FIGS 6 to 8, the perpendicular surface oE a portion of the arm 18 supports an electrical box 17 when flush mounted to the outside surface of the fron~ wall board.
As shown in FIGS 1 & 2, at the other end of the strip 12, a second flange 28 extends perpendicular from the end of the strip 12 on the same side as the fir~t flange 22. Three bend lines 30, 32 and 34 extend across the strip 12, spaced down from the eh~ with the second flange 28. These three bend lines 30, 32 and 34 may have openings in the approximate center of the strip 12 to help ensure that the bend occurs on the bend line~
There are generally two sizes of studs or channels 40 used in the construction of a wall structure as shown in FIGS 5 & 8, a 3 5/8 inch stud identified as dimension A and a 2 1/2 inch stud identified as dimension B. Other sizes of studs having different dimensions can be accommodated with different bend lines or additional bend lines. The bracket 10 is designed to fit in wall structures having either size of stud. In the case of the electrical box 17 being recessed as shown in FXGS 3 5, a box cover 42 is placed over the box 17 having a raised portion 44 which extends to the outside surface of the outer wall board 46~ As shown in FIG 4, the strip 12 is bent at bend line 30 for dimension A and at bend line 34 for dimension B. The bent portion of the strip resting on the surface of the inner uall board 48~
When the electrical box 17 is positioned flush with the outside surface of the outer wall board 46 as shown in FIGS 6 & 8, the strip need not be bent for studs of dimension A, but rests on flange 28 as shown in FIG 7, is bent at bend line 32 to accommodate dimension B studs.
The pairs of locking tongues 50 and 52 are provided for locking the bracket to an electrical box 17. One tongue on each side of the strip 12 forms a pair. Each locking tongue 50 and 52 has a bend line 54 at a slight angle to the strip 12 such that when a tongue 50, 52 is bent about it's bend line 54, it bends closer towards the box so that an electrical box 17 is locked between the tongue 50 or 52 and the hooks 16. By bending towards the box, the tongue 50 or 52 compensates for minor variations in depth for the box. The positions oE
the two pairs of tongues 50, 52 are such that they sui~
two standard sizes of boxes 17. When the electrical box 17 is recessed as shown in FIGS 3 to 5, the box 17 is generally held in position by the ccver plate 42 which is attached to the box 17 and grips the hooks 16 so the bracket 10 is firmly attached. In this mode, it is not essential to use the tongues 50 or 52. However, when the box is flush with the outside surface of the outer wall 46 as shown in FIGS 6 to 8, then the tongue is bent to grip the box~ As shown in the drawings, tongues 52 are bent in to hold the box 17 between the tongues 52 and the hooks 16. If the box 17 is deeper, then the tongues 50 are bent in rather than tongues 52 as illustrated.

A reinforcing rib 56 is shown in the approximate center of the strip 12 extending between the openings in the bend lines 30, 3? and 34 and extending towards the end of the strip 12 with the`hooks 16 and arm 18.
FIGS 9 & 10 illustrate another bracket according to the present invention to fit in wall spaces dimension A or dimension B. The main difference between this bracket and that shown in the other drawings is that single tongues rather than pairs of tongues are provided to hold an electrical box. Tongues 60, 61, 62 and 63 are designed to hold electrical boxes having depth dimensions L, M, N and 0 respectively. Thus the bracket is adaptable for four different depths of boxes and can hold the box in two different wall space dimensions with the box either flush with the outside surace of the wall or recessed in so that it is substantially flush with the inside surface of the outer wall board.
The bend lines as described herein may all be scored in the metal to ensure ease of bending and ensure that the location of bend occurs along the desired line~
The bracket shown in FIGS 9 & 10 has notches at each end of the bend lines, except where the tongues prevent it~
In addition, holes in the center of the strip may also be used. It is believed that the method of adaption of the bracket to different sizes of electrical boxes, depths o studs and location of electrical boxes flush or recessed from ~he wall surface as well as the me~hod o attachment of the bracket to the box is new~
Various changes may be made to the embodiments shown herein without departing from the scope of the present invention which is limited only by ~he following claims~

The bracket 10 is preferably formed from sheet metal and has a flat elongate strip 12 which at one end has a pair of hooks 16 which fit over an open side of an electrical box. The hooks 16 are to hold the box. An arm 18 is positioned between the two hooks 16 with grooves 2n dividing the arm 18 from the hooks 16. At the end of the arm 18 is a first flange 22 which extends perpendicular from the flat elsngate strip 12~
The first flange 22 is used for positioning the bracket 10 when the electrical box 17 is recessed and flush mounted to the inside surface of a front wall board as shown i~ FIGS 3 to 5.
A bend line 24 is placed at the top of the arm 1~ 18 at the termination of the grooves 20. The bend line 24 may include an opening in its approximate center so that the arm may be bent by pliers or some other tool across the bend line 24. When the arm 18 is bent up as shown in FIGS 6 to 8, the perpendicular surface oE a portion of the arm 18 supports an electrical box 17 when flush mounted to the outside surface of the fron~ wall board.
As shown in FIGS 1 & 2, at the other end of the strip 12, a second flange 28 extends perpendicular from the end of the strip 12 on the same side as the fir~t flange 22. Three bend lines 30, 32 and 34 extend across the strip 12, spaced down from the eh~ with the second flange 28. These three bend lines 30, 32 and 34 may have openings in the approximate center of the strip 12 to help ensure that the bend occurs on the bend line~
