Abstract

An electrical box support for supporting an electrical box or other like device in a studded wall. The box support comprises a horizontal strut having a centrally located outwardly opening horizontally extending V-shape channel and a pair of legs formed at each end thereof. The purpose of the V-shape channel is to facilitate horizontal positioning or alignment of such boxes, to facilitate fastening, and also to strengthen the strut. Separating each leg of a leg pair is a cut-out which allows each of the legs to flex and bend independent of the other. To rigidify further and strengthen the box support, the invention further provides a pair of flanges or ribs formed along the lateral edges of the horizontal strut.

Claims

1. An electrical box support for securing with fasteners electrical boxes having substantially flat back surfaces to studded walls, said electrical box support comprising a horizontal strut, means to secure said strut between adjacent studs, said strut comprising a front surface which provides a mounting surface for such box and abuts such back surface of such boxes, and a single V-shape horizontal channel extending along the substantial length of said front surface said strut, said V-shape channel originating from said front surface of said strut such that the apex of said V-shape channel is located rearwardly of said front surface, said V-shape channel serving to ensure that such boxes secured thereto are horizontally aligned with said strut and such fasteners securing such boxes to said strut are aligned with and extend through the apex of said V-shape channel.

2. A box support as set forth in claim 1 wherein said V-shape horizontal channel is positioned in the middle of said strut.

3. A box support as set forth in claim 1 including means at each end of said horizontal strut adjustably to secure said strut to adjacent studs.

4. A box support as set forth in claim 3 wherein said means to secure said horizontal strut between adjacent studs comprises a pair of legs formed at each end of said strut, each of said legs including a first portion which extends almost normal to the axis of said strut and a second portion which extends essentially parallel to the axis of said strut.

5. A box support as set forth in claim 4 wherein said first portion extends at an angle of approximately 15°

to said normal to the axis of said strut.

6. A box support as set forth in claim 5 wherein said means at each end of said horizontal strut adjustably to secure said strut to adjacent studs includes a cut-out originating from the end of said strut which serves to separate each of the legs of said leg pair formed at each end of said strut permitting each of said legs to bend and flex independently of each other.

7. A box support as set forth in claim 6 wherein said cut-outs at each end of said horizontal strut are centrally aligned relative to the middle of said strut.

8. A box support as set forth in claim 7 wherein said second portion of each of said legs includes at least one aperture to facilitate the mounting of said support to such studs with fasteners.

9. A box support as set forth in claim 1 wherein at least one of the lateral edges of said horizontal strut includes a reinforcing flange extending along at least a portion thereof.

10. A box support as set forth in claim 9 wherein said flanges are slightly outwardly flared to facilitate nesting of said box supports.

11. A box support as set forth in claim 9 wherein said support is formed from a galvanized sheet steel.

12. An electrical box support for securing electrical boxes to studded walls comprising a first horizontal strut having a front surface, and a second horizontal strut having a front surface overlappingly nested and interconnected to said first horizontal strut with a fastener, each of said struts having a single V-shape horizontal channel in the middle of said strut extending from the front surface of each of said struts such that the apex of each of said V-shape channels is located rearwardly of its respective front surface, said V-shape channels serving to ensure that such boxes secured thereto are horizontally aligned with said struts and said fastener that is being utilized to interconnect said struts is aligned with and extends through the apex of said V-shape channel, and means at the ends of said struts distally such overlap to secure said struts between adjacent studs.

13. An electrical box support as set forth in claim 12 wherein said fastener in addition to interconnecting said struts also serves to secure such box thereto.

14. An electrical box support as set forth in claim 12 wherein said means to secure said struts between adjacent studs comprises a pair of legs formed at each end distally such overlap, each of said legs including a first portion which extends almost normal to the axis of said struts and a second portion which extends essentially parallel to the axis of said struts.

15. A method of installing an electrical box support between adjacent studs of a studded wall comprising the steps of cutting off and end of a first box support, cutting off one end of a second box support, overlapping and nesting the cut end of such first box support with the cut end of such second box support, interconnecting such first box support to such second box support to form a third box support of a new length, and mounting such third box support between adjacent studs of such studded wall wherein such first and second box supports each include a single centrally disposed V-shaped horizontal channel to ensure that each of such box supports and boxes attached thereto are horizontally aligned.

16. A method as set forth in claim 15 wherein such first box support is interconnected to such second box support by a fastener which also serves to secure a box of such box supports.

17. A method of installing an electrical box support between adjacent studs of a studded wall comprising the steps of cutting off one end of such box support to form a cut-off portion, overlappingly nesting and telescoping said cut-off portion within such cut end of such box support to create a new box support of different shorter length, and interconnecting such cut-off portion to such cut end of such box support with a fastener wherein such cut end of such box support and such cut-off portion both including a single centrally disposed horizontally extending V-shaped channel to ensure that such cut end of said box support and such cut-off portion are horizontally aligned and such boxes attached thereto are horizontally aligned.

18. In combination a box and box support therefor adapted to support and position said box within a wall between vertically extending studs of such wall, said box support comprising a horizontally extending strut having a planar face which provides a mounting surface for said box, means at each end of said strut to support and secure said strut between such studs so that the planar face is recessed with respect to the front of such studs, said strut including a single horizontally extending V-shape channel in the middle of said planar face which is recessed rearwardly from said planar face, said box being secured to said planar face, and a plurality of fasteners extending from said box through the apex of said channel, said channel serving both to horizontally align said box secured to said strut and guide said fasteners through said strut whereby said fasteners are aligned with the apex of said channel.
