Abstract

The present invention is a set of universal support brackets that attach to the side surface of an electrical box and support the box against the inside surface of the opposing wall boards. Moreover, the invention adapts to most electrical steel boxes with any depths, and provides support in hollow wall structures of different depths. After attachment to the electrical junction box, the universal support bracket extends against the back wall surface to prevent the box from being pushed into the hollow space between wall boards; effectively securing the box in place. The brackets are adjustable, and consist of either two or three components, incorporating a ratchet or locking mechanism. The bracket provides small intervals to effectively accommodate the adjustment of numerous sizes of electrical outlet boxes with a variety of hollow wall depths. Mounting and adjustment of the bracket takes only a few seconds.

Claims

1. A universal adjustable support bracket for securing one or more electrical boxes comprising:

A stationary base plate, one end having a pair of opposed bent edges which become substantially parallel to the stationary base plate, and an offset tab on the opposing end parallel to the stationary base plate, having an attachment means for connection to one or more sides of an electrical box.

A sliding part in shape of an elongate strip of sheet metal perforated with a number of generally rectangular holes for fine adjustment, one end having opposed bent edges, as in the stationary base plate, meant for sliding securely inside the stationary base plate, and the other end with a flange directly perpendicular to the elongate strip, the perpendicular flange being generally rectangular with an optional thumb tab for retracting of pushing cut the elongate strip from the stationary base plate, and the flange'"'"'s four corners being flared outwards to help found itself in the opposing wall board.

A locking or ratchet spring clip installed on the stationary base frame by clipping, welding, bolting, riveting or any other type of fastening, resting on the front surface of the stationary base frame providing pivoting points, having at least one tab used to release the locking/ratchet latch from either end of the elongate strip, consisting of two or more extended bent tabs to form the clips and a locking/ratchet latch bent at a substantially 90°

angle for engaging one or more of the plurality of generally rectangular perforated holes, and having a spring mechanism comprised of at least two curved tabs for operating the ratchet spring clip.

3. The universal adjustable Bracket of claim 1, wherein box clip can mount on the edge, or attach to the side of the junction box through the protruding tabs into the box side holes.

4. The universal adjustable Bracket of claim 1, wherein the clip can provide a means of connecting the stationary base to the elongated strip, or the clip itself can be integrated into the elongated strip.

5. The universal adjustable Bracket of claim 1, wherein the components are made of electrically conductive material.

6. The universal adjustable Bracket of claim 1, wherein the stationary base consists of a guiding channel for the elongate strip to slide through.

7. The universal adjustable Bracket of claim 1, wherein the spring mechanism has an angled latch of arbitrary angle to engage the perforated holes of the elongate strip.

8. The universal adjustable Bracket of claim 1, wherein the tab at the end of the elongate strip bends out into one or more barbs to grip itself into the opposing wall.

9. The universal adjustable Bracket of claim 1, wherein the tab at the end of the elongate strip can be shaped as a rectangle, triangle, or any other desired shape.

10. The universal adjustable Bracket of claim 1, wherein the tab on the end of the elongate strip has a flange of any shape for pushing or pulling the elongate strip.

11. The universal adjustable Bracket of claims 1 and 2, wherein the elongate strip has an offset tab used for mounting itself upon the clip attached to the junction box.

16. An electrical junction box comprising said universal adjustable support bracket according to claim 1.

18. An electrical junction box comprising said universal adjustable support bracket according to claim 3.

19. An electrical junction box comprising said universal adjustable support bracket according to claim 11.

2. A universal adjustable support bracket for securing one or more junction boxes, the bracket further comprising:

A stationary junction box clip, having jog bent edges on either side to form an indentation for an elongate strip to glide through, and those jog bent indentations having tabs extending out at an arbitrary angle with means for attachment to the side of an electrical junction box.

A sliding part in shape of an elongate strip of sheet metal, at one end having a stamped out tab with which to secure it to the stationary junction box clip, and at the other end having two tabs substantially perpendicular to the elongate strip, the elongate strip also comprising an integrated spring mechanism at an arbitrary angle between 10°

to 170°

for locking with the ratchet mechanism.

A flat plate of steel sheet metal, having a pair of opposed bent edges which become substantially parallel to the flat plate forming a guiding channel for the elongate stationary strip having two tabs bent at 90°

with at least one hole per tab at one end and a plurality of generally rectangular perforations forming the ratchet mechanism for fine adjustment from the other end towards the middle.

12. The universal adjustable Bracket of claim 2, wherein the elongate strip has two substantially perpendicular tabs used for restricting the lateral movement of the Stationary Base Plate.

13. The universal adjustable Bracket of claim 2, wherein the spring mechanism is integrated into the elongate strip, and forming a pushing tab on one end and forming a ratchet latch on the other end.

14. The universal adjustable Bracket of claim 2, wherein the plurality of the generally rectangular perforated openings form the ratchet steps.

15. The universal adjustable Bracket of claim 2, wherein one or more substantially perpendicular tabs are located on the end of the sliding plate of sheet metal, having at least one hole per tab, and being of rectangular, circular, triangular, or any other geometrical origin.

17. An electrical junction box comprising said universal adjustable support bracket according to claim 2.
