ABSTRACT:
BACKGROUND OF THE INVENTION
Most modern equipment for implementing telecommunications systems contain an electronic apparatus housed in a casing. The casing is generally enclosed, with a front access door, sidewalls, and a backplane. Generally, the electronic apparatus located within the casing is electrically coupled to the backplane. In most instances, the backplane performs an interconnect function between the electronic apparatus within the casing and external cables, wires, and leads (hereinafter “cables”) located outside the casing.
In most instances, the mass of cables which may emanate from the backplane, are allowed to freely dangle from the backplane. In this configuration, the cables may become easily dislodged, which may cause a disruption in the service being provided by the equipment. The mass of cables may also become entangled with other equipment systems, which may pose a hazard to technicians and others who work in close proximity to the equipment system. Finally, because the cables freely dangle form the backplane, undue strain may be placed on the cables, which may cause them to become dislodged or else may cause them to break.
SUMMARY OF THE INVENTION
In accordance with the present invention, a mechanism secures the cables which may emanate from a piece of equipment, such as telecommunications equipment. The present invention reduces the possibility of cables becoming dislodged, entangled, and/or broken, which can cause service disruption or other undesired hazards. The mechanism of the present invention, includes a bar assembly, which has a hollow member in telescopic engagement with an insertable member. Preferably, the insertable member can slide in and out of the hollow member, such that the length of the bar can be varied from a first dimension to a second dimension. The bar assembly of the present invention, also includes telescopically engaged end members, one positioned at each end of the mechanism. Beneficially, the depth of the mechanism, measured from the back of the equipment, may be varied to accommodate differently sized equipment components.
The ability to vary the length and the depth of the mechanism is particularly advantageous since it allows the mechanism to be used universally with equipment having different widths, and having differently sized components. Advantageously, the cables may be tied, anchored, secured, or otherwise fastened to the mechanism, such that the cables cannot be inadvertently dislodged from the equipment system. Because the cables are secured to the mechanism, and therefore not allowed to freely dangle, the potential for straining, tangling, or breaking the cables is reduced, which substantially reduces the possibility of danger to technicians and others.
