Abstract

A mounting bracket for connection to a wall stud between a pair of wall panels is adapted to mount a variety of electrical junction, outlet and switch boxes. When mounted the bracket is a cantilever which is stabilized against deleterious forces by a pair of side-mounted support legs for engaging an opposed wall panel.

Claims

1. A mounting bracket for mounting a switch box to a wall stud within a wall having a pair of opposed wall panels, the switch box including a bottom, a peripheral sidewall extending therefrom to form a cavity, and a pair of threaded tabs, each including a mounting screw therein, extending from said sidewall parallel to said bottom, said bracket comprising:

a planar mounting panel including opposed first and second sections and opposed third and fourth sections connecting said first and second sections and therewith forming a central opening;

a pair of stabilizing legs each extending at a right angle from said planar mounting panel and each including a distal end for engaging an opposed wall panel;

mounting means including a threaded mounting hole in said third section and a threaded mounting hole in said fourth section for receiving the mounting screws of said box to secure said box to said mounting panel; and

bracket mounting means including a pair of spaced holes in said first section for receiving fasteners to secure said bracket to said stud.

2. A mounting bracket for mounting a switch box to a wall stud which extends between a pair of opposed wall panels, the switch box comprising a bottom, a peripheral sidewall extending from the bottom to form a cavity, a top mounting ear adjustably connected to the sidewall including a pair of threaded holes, and a bottom mounting ear adjustably connected to the sidewall including a pair of threaded holes, said bracket comprising:

a planar mounting panel including a front surface, a rear surface, opposed first and second sections and opposed third and fourth sections connecting said first and second sections and therewith defining a central opening;

a pair of stabilizing legs each extending at a right angle from said mounting panel and each including a distal end for engaging an opposed wall panel;

mounting means including a pair of threaded holes in said third section, a pair of threaded holes in said fourth section and a first pair of mounting screws threadedly engaging said threaded holes of said top mounting ear and said threaded holes of said third section and a second pair of mounting screws threadedly engaging said threaded holes of said bottom mounting ear and said threaded holes of said fourth section; and

bracket mounting means including a pair of spaced holes in said first section for receiving fasteners for securing said bracket to said stud.

3. A mounting bracket for electrical boxes, said bracket adapted to be mounted to a wall stud between opposed wall panels, said bracket comprising:

opposed first and second planar sections and opposed third and fourth planar sections connecting said first and second opposed planar sections and therewith defining a central opening;

a pair of openings through said first section for receiving fasteners to mount said bracket to the stud;

a pair of legs respectively generally parallel to said third and fourth sections and adapted to be bent at a right angle, each of said legs including a distal end for engaging an opposed wall panel and provide support and stability for said bracket; and

means in said opposed third and fourth sections for mounting an electrical box thereto.

4. The mounting bracket of claim 3, wherein:

said distal end of each of said legs comprises a sub-portion bent at a right angle to said leg.

5. The mounting bracket of claim 3, wherein:

said first and second sections each include an offset whereby the plane of said panel is recessed with respect to the plane of said first section.

6. The mounting bracket of claim 3, wherein:

said third and fourth sections each include a profiled edge at said central opening and each of said edges comprises arcuate portions so that there are no sharp edges in said central opening.

7. The mounting bracket of claim 3, in combination with another mounting bracket of the same structure, wherein:

said second section comprises a pair of holes spaced equal to the spacing of said holes of said first section of other bracket for alignment therewith and for receiving fasteners to secure said brackets together.

8. A mounting bracket for mounting to a wall stud between a front wall panel and a rear wall panel and for mounting an electrical box of the first type which includes a bottom, a plurality of sidewalls extending from the bottom to form a cavity and at least one pair of diagonally disposed threaded mounting tabs extending over the cavity parallel to the bottom and including first threaded fasteners each having a shank and a head, and for mounting an electrical box or a second type which includes a bottom and a plurality of sidewalls extending from the bottom to form a cavity and at least one pair of diagonally disposed threaded mounting tabs extending over the cavity parallel to the bottom and including second threaded fasteners each having a shank and a head, the diagonal spacing of the first threaded fasteners being a first predetermined distance and the diagonal spacing of the second threaded fasteners being a greater, second predetermined distance, said bracket comprising:

a planar mounting panel including opposed first and second sections and opposed third and fourth sections connecting said first and second sections to define a central opening therebetween;

a pair of legs each cut from the material of said third and fourth sections and connected to and extending generally perpendicular to said mounting panel, each of said legs including a distal end for engaging the rear wall panel;

electrical box mounting means comprising a first slot in said third section dimensioned to receive the shank of a threaded fastener therethrough, a second slot in said fourth section including a first portion dimensioned to receive the head of a threaded fastener therethrough and a second portion to receive the shank of the threaded fastener therethrough, said first and second slots spaced equal to the spacing of said first threaded fasteners for mounting an electrical box of the first type, a third slot in said fourth section dimensioned to receive the head of a threaded fastener therethrough and spaced from said first slot equal to the spacing of said second fasteners for mounting an electrical box of the second type;

a first portion of said first section offset from the plane of said mounting panel and including a pair of spaced holes for receiving fasteners for mounting said bracket to the wall stud.
