Abstract

A box bracket includes mounting brackets with upper and lower lateral telescoping arms and a sliding mount. The mounting bracket includes an end piece for attaching to a vertical stud, and inner and outer lateral arms overlapping with arms of an opposing mounting bracket to form the telescoping arms. The mounting bracket may be used as a left or right mounting bracket. The sliding mount includes a forward facing face for mounting an electrical box and vertically spaced apart mouths on left and right sides of the sliding mount, the upper and lower telescoping arms passing through the mouths. The mouths are formed in mouth frames, and after positioning the sliding mounts, the mouth frames may be bent inward against the telescoping arms to hold the position of the sliding mount on the arms. One or more sliding mounts may reside on a single box bracket subject to stud spacing.

Claims

1. An adjustable box bracket comprising:

a left mounting bracket comprising;

a left end piece for attaching to a first vertical stud;

a left upper outer arm attached to the left end piece; and

a left lower inner arm attached to the left end piece below and parallel with the left upper outer arm;

a right mounting bracket comprising;

a right end piece for attaching to a second vertical stud adjacent to and spaced apart from the first vertical stud;

a right upper inner arm attached to the right end piece and telescopingly partially residing inside the left upper outer arm; and

a right lower outer arm attached to the right end piece below and parallel with the right upper inner arm and telescopingly partially residing outside the left lower inner arm;

a sliding mount having;

a face for attaching an electrical box; and

right and left sides having vertically spaced apart upper and lower left and right mouths respectively, the upper telescoping arms passing through both right and left upper mouths and the lower telescoping arms passing through both right and left lower mouths,

wherein, the telescoping arms are adjustable to position the end pieces over the studs for attaching to the studs and the sliding mount is slidable along the telescoping arms to position the electrical box at any position along the full lengths of the telescoping arms.

2. The adjustable box bracket of claim 1, wherein:

the right and left mouths are formed in bendable mouth frames, and prior to positioning the sliding mount on the telescoping arms, the bendable mouth frames are bendable away from an adjacent side of one of the telescoping arms to disengage the adjacent side to allow movement of the sliding mount on the telescoping arms; and

after positioning the sliding mount on the telescoping arms, the bendable mouth frames are bendable towards the adjacent side of the telescoping arms to engage the adjacent side to resist movement of the sliding mount on the telescoping arms.

3. The adjustable box bracket of claim 2, wherein:

the right and left mouths includes forward pointing points on rear edges of the mouths;

the points are bendable away from the adjacent side of the telescoping arm to disengage the adjacent side to allow movement of the sliding mount on the telescoping arms, and

the points are bendable towards the adjacent side of the telescoping arm to engage the adjacent side to resist movement of the sliding mount on the telescoping arms.

4. The adjustable box bracket of claim 1, wherein a face of the sliding mount includes fixing screw holes residing over the arms for fixing screws, and the fixing screws are installed through the fixing screw holes to reside against the arms to resist movement of the sliding mount on the telescoping arms.

5. The adjustable box bracket of claim 4, wherein the fixing screw holes comprise four fixing screw holes, one near each corner of the face of the sliding mount.

6. The adjustable box bracket of claim 1, wherein the left upper outer arm, the left lower inner arm, the right upper inner arm, and the right lower outer arm all have a “

U”

cross-section.

7. The adjustable box bracket of claim 1, wherein:

the left upper outer arm and the right upper inner arm have a downward opening “

U”

cross-section; and

the left lower inner arm and the right lower outer arm all have an upward opening “

U”

cross-section.

8. The adjustable box bracket of claim 1, wherein the sliding bracket includes integral strapping for both EMT and armored cable.

9. An adjustable box bracket comprising:

a left mounting bracket comprising;

a left end piece for attaching to a first vertical stud;

a left upper outer arm attached to the left end piece; and

a left lower inner arm attached to the left end piece below and parallel with the left upper outer arm;

a right mounting bracket comprising;

a right end piece for attaching to a second vertical stud adjacent to and spaced apart from the first vertical stud;

a right upper inner arm attached to the right end piece and telescopingly partially residing inside the left upper outer arm; and

a right lower outer arm attached to the right end piece below and parallel with the right upper inner arm and telescopingly partially residing outside the left lower inner arm;

a sliding mount having;

a face for attaching an electrical box;

right and left sides having vertically spaced apart upper and lower left and right mouths respectively, the upper telescoping arms passing through both right and left upper mouths and the lower telescoping arms passing through both right and left lower mouths; and

the right and left mouths formed in bendable mouth frames, wherein;

prior to positioning the sliding mount on the telescoping arms, the bendable mouth frames are bendable away from an adjacent side of one of the telescoping arms to disengage the adjacent side to allow movement of the sliding mount on the telescoping arms; and

after positioning the sliding mount on the telescoping arms, the bendable mouth frames are bendable towards the adjacent side of the telescoping arms to engage the adjacent side to resist movement of the sliding mount on the telescoping arms,

wherein, the telescoping arms are adjustable to position the end pieces over the studs for attaching to the studs and the sliding mount is slidable along the telescoping arms to position the electrical box at any position along the full lengths of the telescoping arms.

10. An adjustable box bracket comprising:

a left mounting bracket comprising;

a left end piece for attaching to a first vertical stud;

a left upper outer arm attached to the left end piece; and

a left lower inner arm attached to the left end piece below and parallel with the left upper outer arm;

a right mounting bracket comprising;

a right end piece for attaching to a second vertical stud adjacent to and spaced apart from the first vertical stud;

a right upper inner arm attached to the right end piece and telescopingly partially residing inside the left upper outer arm; and

a right lower outer arm attached to the right end piece below and parallel with the right upper inner arm and telescopingly partially residing outside the left lower inner arm;

a sliding mount having;

a face for attaching an electrical box;

right and left sides having vertically spaced apart upper and lower left and right mouths respectively, the upper telescoping arms passing through both right and left upper mouths and the lower telescoping arms passing through both right and left lower mouths; and

fixing screw holes residing on the face of the sliding mount over the arms for fixing screws, and the fixing screws are installed through the fixing screw holes to reside against the arms to resist movement of the sliding mount on the telescoping arms,

wherein, the telescoping arms are adjustable to position the end pieces over the studs for attaching to the studs and the sliding mount is slidable along the telescoping arms to position the electrical box at any position between the studs.
