## Title
Adjustable mounting bracket

## Abstract

A bracket is provided for mounting conduit clamps or pipe clamps to the face of the bracket. The height of the bracket can be adjusted by removing pins that are attached to mounting bracket feet and mounting bracket arms. Multiple holes may be formed in the mounting bracket arm and mounting bracket feet to allow for various alignments of the bracket arms, which will vary the height of the bracket. The height is adjusted through a pair of four-bar linkages that enable a linear motion of the bracket face. The bracket may have a footprint that is smaller than conventional adjustable mounting brackets.

## Background
STATEMENT OF GOVERNMENT INTEREST
The invention described was made in the performance of official duties by one or more employees of the Department of the Navy, and thus, the invention herein may be manufactured, used or licensed by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.


BACKGROUND
The invention relates to mounting brackets and, more particularly, mounting brackets for mounting pipe or conduit clamps that is adjustable in height with a minimal footprint.
A conduit which houses electrical wires or cables is generally supported over the length of its run on a support surface such as an electric pole, a building, or other structure. The conduit is generally supported in a parallel spaced arrangement on the support surface by a clamping device.
Most conventional height adjustable brackets utilize either a swinging arm mechanism or a linear slide to adjust the bracket. Both require a large footprint for the bracket. There is a need for an amounting bracket for mounting pipe or conduit clamps that is adjustable in height with a minimal footprint.

DETAILED DESCRIPTION
In the following detailed description of exemplary embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific exemplary embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention.
Other embodiments may be utilized, and logical, mechanical, and other changes may be made without departing from the spirit or scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
Broadly, the current invention provides a bracket that permits the mounting of conduit clamps or pipe clamps to the face of the bracket. The height of the bracket can be adjusted by removing pins that are attached to mounting bracket feet and mounting bracket arms.
Multiple holes may be formed in the mounting bracket arm and mounting bracket feet to allow for various alignments of the bracket arms, which will vary the height of the bracket. The height is adjusted through two four-bar linkages that allow for a linear motion of the bracket face. The bracket of the current invention may have a footprint that is smaller than conventional adjustable mounting brackets.
Referring now to the drawings, and more particularly to FIGS. 1 through 5, a mounting bracket 10 may include a bracket face 12 that is adjustable in height by a four-bar linkage 14. A first end of a long bracing bracket 16 may pivotably attach to each side of each end of the bracket face 12. A clevis pin 24, for example, may be used to provide the pivoting attachment between the long bracing bracket 16 and the bracket face 12. A second, opposite end of the long bracing bracket 16 may pivotably attach to a bearing block 18. A shoulder screw 26, for example, may be used to provide the pivoting attachment between the long bracing bracket 16 and the bearing block 18.
A proximal end of a short bracing bracket 20 may pivotably attach to a central section 22 of each of the long bracing brackets 16. Clevis pins 24 may be used to provide the pivoting attachment between the short bracing bracket 20 and the long bracing bracket 16. An opposite distal end of the short bracing bracket 20 may include a plurality of mounting holes 28 and 29.
The mounting hole 29 may be used to pivotably attach the short bracing bracket 20 to a mount 30 with, for example, a short bracing bracket clevis pin 38. The mounting holes 28 may include two mounting holes adapted to receive a pin 32. The mount 30 may include a plurality of holes 36 that align with the mounting holes 28 in the short bracing bracket 20 as the short bracing bracket 20 is pivoted about the short bracing bracket clevis pin 38. The pin 32 may adjust the angle of the short bracing bracket 20 relative to a mounting surface 34, thereby adjusting the height, relative to the mounting surface 34, of the bracket face 12.
The bearing block 18 may be disposed to move along the mounting surface 34 as the height of the bracket face 12 is changed. However, surface irregularities in the mounting surface 34 may hinder movement of the bearing block 18. In some embodiments, the bearing block 18 may have a bearing sleeve 40. Typically, the bearing sleeve 40 may be press fit into a hole in the bearing block 18. First and second clamps 42, 44 may support a bearing travel bar 46 off from the mounting surface 34. The bearing block 18 may travel along the bearing travel bar 46, thereby permitting smooth height adjustment of the bracket face 12.
Referring now to FIGS. 6 through 10, the mounting bracket 10 may be mounted on a panel sub-assembly 50. The pins 32 may be affixed to the panel sub-assembly 50 via a wire 52 connected to a tab 62 secured to the mounting surface 34 by a nut 64, for example, to keep the pins 32 readily available while the height of the bracket face 12 is adjusted.
The bracket face 12 may be adapted to hold a plurality of conduit clamps or pipe clamps 54 as shown in FIG. 10. In some embodiments, the bracket face 12 may have slot 56 cut therein to accept bolts 58 of the conduit or pipe clamps 54. The slot 56 may permit an operator to loosen nuts 60 on the bolts 58 to permit the clamp 54 to slide lengthwise along the slot 56.
While the above describes the bracket 10 having a set of bracing brackets (short bracing bracket 20 and long bracing bracket 16) on each side of the bracket face 12, in some embodiments, a single set of bracing brackets may be used to provide a similar adjustment mechanism as is obtained with two sets of bracing brackets.
While certain features of the embodiments of the invention have been illustrated as described herein, many modifications, substitutions, changes and equivalents will now occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the embodiments.
