ABSTRACT:
BACKGROUND OF THE INVENTION
Communications installations utilize relay racks for a variety of purposes. One of such purposes is to support auxiliary equipment. To this end, it is often desirable to provide a shelf on a relay rack to receive and support a variety of types of equipment. The space requirements in a communications installation demand that space be optimized. In addition, it is desirable for a shelf on a relay rack to be easily mounted on the relay rack and securely positioned. It is also desirable to provide a shelf for use on a relay rack which may be installed by a single individual to make the installation of the shelf efficient. Furthermore, a relay rack with a shelf must have a high degree of stability.
BRIEF SUMMARY OF THE INVENTION
The subject communications equipment relay rack comprises a pair of spaced apart parallel upright columns. A mounting ear is secured to each upright column at a selected height on the respective column. Each mounting ear is in the same horizontal plane as the other mounting ear. A support peg is fixed to each mounting ear. Each of the support pegs extends toward the support peg of the other mounting ear. A shelf is mounted between the spaced apart upright columns. The shelf includes a floor having a pair of opposed edges. A mounting side is secured to each of the opposed edges of the floor. Each mounting side is substantially perpendicular to the floor. Each of the mounting sides has a shelf mounting aperture receiving a respective support peg to hold the shelf between the columns.
