ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to cabinets for the installation of electronics equipment including telecommunications equipment, and more particularly, to cabinets that provide access to the equipment within.
Particular types of electronics and telecommunications installations require various components connected together with a myriad of wires and cables. For example, certain telecommunications installations for telephone customers receive a fiber optic bundle from the local telephone company. To connect to the customer's phone lines, equipment is needed to convert the wide band optical signals to narrow band digital signals, and other equipment is needed to convert the narrow band digital signals to analog. A rectifier is required to convert the power from local 120 volt outlets, and back up batteries are needed in case the local power source fails.
Typically, the various equipment components are installed on stationary racks and/or shelves. Installing the equipment on racks or shelves near or mounted on the wall can be problematic as access to the wire and cable connectors on the rear of the equipment is difficult if not impossible.
Moreover, present shelf and rack systems are not easily integrated with the power supply and batteries. Major improvements over present installations are necessary to provide simpler, less costly, and easier to maintain installations.
Accordingly it is an object of the present invention to provide an electronics cabinet assembly that can integrate the electronics equipment and power supply.
Another object is to provide an electronics cabinet assembly that is easy to install.
A further object is provide an electronics cabinet assembly that can be mounted on the wall or on a pedestal.
A still further object is to provide an electronics cabinet assembly that provides access to the wire and cable connections in the rear of the equipment.
Another object is to provide an electronics cabinet that can be stacked on top of other cabinets and equipment and still provide access to the rear of the equipment.
Additional objects, advantages and novel features of the invention will be set forth in part in the description that follows, and in part will become apparent to those of ordinary skill in the art upon review of the following or may be learned by practice of the invention.
SUMMARY OF THE INVENTION
In broad terms, the objects and advantages of the present invention can be attained by providing an electronics cabinet assembly having a support shelf and an equipment module which is movably supported on the support shelf. The equipment, module, having a front and a rear, is moveable between a closed position adjacent the rear of the support shelf, and an extended position in which it is substantially forward relative to the support shelf. When the equipment module is in the extended position, it is hingably supported on the support shelf to be tiltable about a pivot axis such that the front of the equipment module can tilt downwards to expose the rear of the equipment housed within.
Whether wall or pedestal mounted, the cabinet assembly provides for simplified installation of the equipment module. The support shelf is typically installed or mounted first without the heavier equipment module. The equipment module is then placed onto the pre-installed support shelf and attached thereto. Access to the rear of the equipment module for making the wire and cable connections is readily provided: the equipment is moved forward to its extended position where the front of the equipment module tilts downward to expose the rear. The cabinet assembly can be stacked and bundled with other equipment or other such cabinet assemblies. Access to the connectors for installation and wiring is again provided simply by moving the particular cabinet assembly forward to clear the other equipment where it tilts downward to expose the rear.
The support shelf preferably includes a track on which the equipment module is movably supported. When in the closed position, the equipment module is at least substantially supported on the track. When in the extended position, the equipment module is substantially forward relative to the support shelf and substantially off of the track where it is hingably supported by the support shelf for tilting.
The cabinet assembly can include a wire and cable trough between the rear of the equipment module and the support shelf for the wires and cables. In this manner, the cabinet assembly can be attached directly to a wall as the trough for the wires and cables is within the cabinet assembly. Whether wall or pedestal mounted, the cabinet assembly provides a secured, efficient housing for the equipment and wires and cables.
