Abstract
A mounting arrangement includes a first bracket, a second bracket including a slot, and a series of washers, with two resilient washers. First and second bolts extend through the first bracket, a first and second of the washers, the slot of the second bracket, a third and fourth of the washers, the resilient washers, and a fifth and sixth of the washers. The second bracket frictionally engages the first and second washers, and frictionally engages the third and fourth washers. The resilient washers are each located between the respective first, second, third and fourth washers, and the fifth and sixth washers. The bolts are engaged by nuts compressing the first and second resilient washers with a compressive force between the washers, supporting the first bracket and the second bracket relative to each other and permitting the first bracket and the second bracket to slide relative to each other.
Description
BACKGROUND OF THE INVENTION

The present disclosure relates generally to the field of sliding joints. The present disclosure relates specifically to a mounting arrangement for slidably mounting a display unit, with the mounting arrangement providing a constant compressive force to support the display unit.


Traditional sliding joints lack a constant compression to facilitate sliding one body relative to another. Such sliding joints are at risk of wearing out over time, thus yielding a poor mounting system for crucial machine components. A need exists for a sliding joint with a constant compression provided by an appropriate durometer or stiffness of the materials used in the sliding joint, which would allow for a wide range of frictional characteristics of the sliding joint.


SUMMARY OF THE INVENTION

A mounting arrangement, for slidably mounting a display unit, includes a first bracket, having a first face and a second face, and first and second holes extending through the first bracket from the first face to the second face. The first face of the first bracket is attachable to the display unit adjacent to the display unit. A second bracket has a third face and a fourth face, and includes a slot spanning at least a portion of a width of the second bracket. The slot extends from the third face to the fourth face. A pair of first and second nylon washers each has a central hole. A pair of third and fourth nylon washers each has a central hole. A pair of first and second resilient washers each has a central hole, with the resilient washers having a resiliency greater than a resiliency of each of the first, second, third and fourth nylon washers. A pair of fifth and sixth washers each has a central hole. At least first and second bolts each have a head and a threaded shaft, with the bolts extending through the respective holes in the first bracket, the respective holes of the first and second nylon washers, the slot of the second bracket, the respective holes of the third and fourth nylon washers, the respective holes of the first and second resilient washers and the respective holes of the fifth and sixth washers. The third face of the second bracket frictionally engages the first and second nylon washers, the fourth face of the second bracket frictionally engages the third and fourth nylon washers, and the first and second resilient washers are each located between the respective first, second, third, and fourth nylon washers and the fifth and sixth washers. A pair of first and second nuts engages the respective threads of the first and second bolts such that the first and second resilient washers are compressed with a respective compressive force between the respective nylon washers to support the first bracket and the second bracket relative to each other and permit the first bracket and the second bracket to slide relative to each other.
