Docket No. 97412-PA
Inventor: Lippa - MOUNTING P]ATE AN~ COVER
FOR TWO ELECTRICAL BOXES
IN THE SAME HORIZONTAL PLANE
AND METHOD F'OR INSTALLATION
FIELD OF THE INVENTION
The present invention relat~s to an apparatus and a method for installing at least one electric~l outlet box on a stud and, more particularly to an apparatus having two openings for mounting the electrical outlet boxes straddling and abutting a wood or metal stud in a wall such that the electrical outlet boxes are aligned in the same horizontal plane.
BACKGROUND OF THE INVENTION
In the course of constructing or rehabilitating a building, there is a need to mount many electrical outlet boxes in the wall to provide a safe means for housing electrical fixtures such as electrical switches, convenience outlets, electrical terminals, telephone outlets, data terminals, etc. The electrical outlet boxes are commonly four (4) inch square boxes or four and eleven sixteenths (4 11/16) inch boxes. The electrical outlet box may be supported by a variety of methods. U.S. Patent No. 5,450,974 to Lippa discloses a mounting plate and cover assembly for an electrical outlet box which permits the secure mounting of the electrical outlet box abutting a sidewall of a stud and preventing movement of the electrical outlet box. However, the assembly is for one outlet box and does not disclose the installation of two boxes in the same horizontal plane. There is a need for having two electrical boxes or one electrical box and a telephone/data outlet Docket No. 97412-PA
Inventor: Lippa aligned in a horizontal plane and straddling a wall stud. Thi.c need has become more critical with the rapid expansion of computers and facsimile equipment where the telephone outlet or data outlet is most conveniently located in the immediate vicinity of a power source for the computer and/or f~csimile device. It is difficult and time consuming to install the outlets on opposite sidewalls of a single wall stud at exactly the same height above the floor.
U.S. Patent No. 4 503 789 to Medlin Sr. discloses mounting a pair of outlet boxes on a common stud but uses two separate boxes individually mounted. In all e~odiments the electrical outlet boxes do not abut the stud and require stiffening arms to support the electrical outlet boxes to a rear wall.
U.S. Patent No. 4 753 361 to Medlin Jr. discloses pairs of electrical switch boxes mounted on opposite sides of a single stud.
The separate mounting brackets are abutting or "piggyback" and require separate installation. ~urthermore the brackets have stabilizing extension arms and the boxes do not abut the wall stud.
U.S. Patent No. 5 025 944 to Rodick discloses two electrical receptacles spot welded to a connecting member. The connecting member is placed over the wall st:ud with the electrical receptacles adjacent to the side surfaces of the wall stud. A cover plate is required over the face of the receptacles.
It can be seen that there is a need for a simple relatively inexpensive device to install electrical boxes abutting both sides Docket No. 97412-PA
Inventor: Lippa of a wal-L stud so that the electrical boxes are in the same horizontal plane.

The flange portion 20 has a top edge 30 and a bottom edge 32.
A projecting tab 34 is formed on the top edge 30 and a similar projecting tab 34 is formed on the bottom edge 32 of the flange portion 20. The projecting tabs 34 are formed on the back surface of the flange portion 20 and are approximately perpendicular to the back surface. The projecting tabs 34 are in the same vertical plane and are inward of the elongated openings 26. Preferably, another pair of identical projec~_ing tabs 34 are formed near the other opening 12 in the mounting plate and cover 10. The two vertical pairs of projecting tabs 34 are cpaced apart by a distance which is sufficient to permit the respective pairs of projecting tabs 34 to straddle the wall stud 24.
The electrical outlet box 23 contains therein at least one electrical fixture such as a convenience outlet, an electrical switch, electrical terminals etc. As shown in FIGS. 4-5, the Docket No. 97412-PA
Inventor: Lippa electrical outlet box 28 is connected to one of the openings 12 in the mounting plate and cover 10 by a plurality of fastening means 36. The fastening means 36 may be threaded screws, nuts and bolts or other commonly used fasteners. One fastening means 30 is received in each of the plurality of elongated openings 26 in the mounting plate and cover 10. The mounting plate and cover 10 is adjusted on the electrical outlet box 28 by moving the mounting plate and cover 10 with respect to the elongated openings 26. The fastening means 36 are tightened and the mounting plate and cover 10 is secured to the outlet box 28.
The respective openings 12 in the mounting plate and cover 10 may be dimensioned to receive a single size electrical outlet box 28 or a double size electrical outlet box 28 as required for the specific installation. Also, for telephone outlets and data outlets, which are low voltage, -here may not be an electrical outlet box connected to the mounting plate and cover 10, depending upon the electrical code of the community. The mounting plate and cover 10 may have two openings to accommodate two single size boxes, two double size boxes, a ,ingle box with a double box, or no box with either a single or a double box.
If required, a second elect:rical outlet box 28 is connected to the second opening 12 in the mounting plate and cover 10.
The mounting plate and cove:r 10 with the attached electrical box(es) 28 is placed adjacent to the wall stud 24 such that one vertical pair of projecting tabs 34 are abutting a sidewall of the Docket No. 97412-PA
Inventor: Lippa wall stud 24. The electrical outlet box 28 is also solidly abutting the sidewall of the wall stud 24. The other vertical pair of projecting tabs 34 and the other electrical box 28 is disposed on the opposite sidewall of the wall stud 24 and are spaced a small distance from the opposite side wall of the wall stud 24. The flange portion 20 is disposed against the front face of the wall stud 24. The mounting plate and cover 10 with the attached electrical box(es) 28 is moved vertically on the wall stud 24 to position the bottom edges 16 of the openings 16 in the cover 10 at a desired distance above the floor of the installation. The projecting tabs 34 and electrical box 28 are maintained in an abutted position against the sidewall of the wall stud 24. In this manner, the bottom edge 16 of both openings are in the same horizontal plane and are an equal distance above the floor as shown in FIG. 6. The distance D is equal to the distance D'. At least two securing means 38 are disposed in the corresponding holes 22 in the flange portion 20 with one securing means 38 being received in each hole 22. The securing means 38 may be any common securing means such as a wood screw or a nail if the wall stud 24 is wood or, if the wall stud 24 is metal, the securing means 38 may be a self-tapping metal screw, a rivet, a nut and bolt, etc. (FIGS. 7-10). Tightening the securing means 38 assures the disposition of the mounting and cover 10 and attached outlet box(es) 28 to the wall stud 24 such that movement :in any direction is prevented.
Docket No. 97412-PA
Inventor: Lippa Also formed in the approximate midpoint of the flange portion 20 is a vertical elongated slot 40. The elongated slot is used to visually assist in the placement of the flange portions 20 over the wall stud 24.
The mounting plate and cover 10 electrical box 28 assemblv is covered by the wall W such that an opening in the wall W receives the raised rib 18 of the mountin~ plate and cover 10. The upper surface of the raised rib 18 is substantially flush with the outer surface of the wall W due to the height of the raised rib 18 being approximately the same as the thickness of the wall W. Thus, the electrical fixture within the el=ctrical box 28 is readily accessible to a user (FIGS. 11-13). The electrical output is conveniently mounted in the wall immediately adjacent to the telephone or data outlet so that a computer or data processing apparatus can be operated withou having long extension and connecting cables.
In this manner, the electrical box 28 with the electrical fixture therein is firmly mounted between the covering front wall W
and a back wall. Movement of the electrical box 28 in any direction is prevented by severa:l factors peculiar to the present invention. The disposition of the electrical box 28 solidly abutting the side wall of the wa.Ll stud 24 severely limits any horizontal or angular movement w:ith respect to the wall stud 24.
Also the abutting of the projecting tabs 34 further limit movement of mounting plate and cover 20 and the connected electrical box(es) Docket No. 97412-PA
Inventor: Lippa 28. Further, any deflection movement with respect to the wall stud 24 is limited. This limitation of horizontal, angular and deflectional movement is further reinforced by securing the flange portion 20 to the front face of the wall stud 24. In addition, vertical movement with respect to the wall stud 28 is prevented by the securing of the flange portion 20 to the front face of the wall stud 24. Further limitation of movement of the electrical box 28 mounting plate and cover 10 assembly is provided by the covering wall W. In addition, the electr:ical boxes 28 are in the same horizontal plane and are a predetermined distance above the floor.
Thus, the assembly of the present invention achieves solid installation without the need for a supporting arm between the front wall and the rear wall of a building structure and without the need for an L-shaped bracket to be attached to the stuc' on the side opposite from the outlet bo,c. In addition, the present invention has only one unitary mounting plate and cover 10 which serves the function of a box support and a raised cover for two adjacent boxes, thereby providing cost efficiency by reducing the number of parts and the labor tir~e to assemble and install as compared to the prior art. The present invention may be rapidly and economically assembled at the job site or it may be preassembled and brought to the job site. The preassembly is possible because there is no need to adjust the length o a far side box support for each electrical box as in the prior art.
Docket No. 97412-PA
Inventor: Lippa Obviously, many modifications may be made without departing from the basic spirit of the pre,ent invention. Accordingly, it will be appreciated by those ski:lled in the art that within the scope of the appended claims, the invention may be practiced other than has been specifically described herein.

The mounting plate and cover 10 electrical box 28 assemblv is covered by the wall W such that an opening in the wall W receives the raised rib 18 of the mountin~ plate and cover 10. The upper surface of the raised rib 18 is substantially flush with the outer surface of the wall W due to the height of the raised rib 18 being approximately the same as the thickness of the wall W. Thus, the electrical fixture within the el=ctrical box 28 is readily accessible to a user (FIGS. 11-13). The electrical output is conveniently mounted in the wall immediately adjacent to the telephone or data outlet so that a computer or data processing apparatus can be operated withou having long extension and connecting cables.
In this manner, the electrical box 28 with the electrical fixture therein is firmly mounted between the covering front wall W
and a back wall. Movement of the electrical box 28 in any direction is prevented by severa:l factors peculiar to the present invention. The disposition of the electrical box 28 solidly abutting the side wall of the wa.Ll stud 24 severely limits any horizontal or angular movement w:ith respect to the wall stud 24.
Also the abutting of the projecting tabs 34 further limit movement of mounting plate and cover 20 and the connected electrical box(es) Docket No. 97412-PA
Inventor: Lippa 28. Further, any deflection movement with respect to the wall stud 24 is limited. This limitation of horizontal, angular and deflectional movement is further reinforced by securing the flange portion 20 to the front face of the wall stud 24. In addition, vertical movement with respect to the wall stud 28 is prevented by the securing of the flange portion 20 to the front face of the wall stud 24. Further limitation of movement of the electrical box 28 mounting plate and cover 10 assembly is provided by the covering wall W. In addition, the electr:ical boxes 28 are in the same horizontal plane and are a predetermined distance above the floor.
Thus, the assembly of the present invention achieves solid installation without the need for a supporting arm between the front wall and the rear wall of a building structure and without the need for an L-shaped bracket to be attached to the stuc' on the side opposite from the outlet bo,c. In addition, the present invention has only one unitary mounting plate and cover 10 which serves the function of a box support and a raised cover for two adjacent boxes, thereby providing cost efficiency by reducing the number of parts and the labor tir~e to assemble and install as compared to the prior art. The present invention may be rapidly and economically assembled at the job site or it may be preassembled and brought to the job site. The preassembly is possible because there is no need to adjust the length o a far side box support for each electrical box as in the prior art.
Docket No. 97412-PA
Inventor: Lippa Obviously, many modifications may be made without departing from the basic spirit of the pre,ent invention. Accordingly, it will be appreciated by those ski:lled in the art that within the scope of the appended claims, the invention may be practiced other than has been specifically described herein.
