## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Patent Application No. 61/412,439, filed on Nov. 11, 2010, the subject matter of which is incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
The present invention relates to an equipment rail and bracket assembly, and more particularly, an equipment rail and bracket assembly for a cabinet.
FIGS. 1-8 illustrate an equipment rail and bracket assembly 100, such as Panduit's Equipment Rail and Bracket Assembly (e.g., Part. No S75RC), according to the prior art.
As shown in FIGS. 1-3, the equipment rail and bracket assembly 100 includes an equipment rail 110 and a pair of bracket assemblies 120. Each of the bracket assemblies 120 includes a bracket 121, a clamp 122, and a plurality of fasteners 123 for mounting the equipment rail 110 to the bracket 121 and the bracket 121 to the clamp 122. The equipment rail 110 includes a plurality of bracket mounting openings 111 for receiving the fasteners 123 to mount the equipment rail 110 to the bracket 121. Additionally, the equipment rail 110 includes a plurality of equipment mounting openings 112 for receiving fasteners (not shown), such as cage nuts, to mount equipment (not shown), such as servers and switches, to the equipment rail 110.
As shown in FIGS. 4-6, the equipment rail and bracket assembly 100 is mounted to a cabinet 10, such as Panduit's Net-SERVTM Cabinet (e.g., Part No. S752C122B). The cabinet 10 includes 4 posts 11, 4 front-to-back beams 12, and 4 side-to-side beams 13, which are welded together at respective corners.
As shown in FIGS. 7 and 8, when the cabinet 10 is assembled, the front-to-back beams 12 are oriented at slight angles with respect to the posts 11. Consequently, when the equipment rail and bracket assembly 100 is mounted to the cabinet 10, the orientation of the front-to-back beams 12 causes the equipment rail 110 to bow, which is particularly undesirable when mounting equipment of a fixed width.
Therefore, there is a need for an improved equipment rail and bracket assembly for a cabinet.
SUMMARY OF THE INVENTION
Certain embodiments of the present invention provide an equipment rail and bracket assembly. The equipment rail and bracket assembly includes an equipment rail and a bracket. The equipment rail is mounted to the bracket. The equipment rail includes a relief cut-out and a flexible tongue formed by the relief cut-out. The flexible tongue includes a bracket mounting opening for mounting the equipment rail to the bracket. The flexible tongue rotates relative to the equipment rail when the bracket is mounted to a cabinet.

DETAILED DESCRIPTION
FIGS. 9-16 illustrate an equipment rail and bracket assembly 200 according to an embodiment of the present invention.
As best seen in FIGS. 9 and 10, the equipment rail and bracket assembly 200 is similar to the equipment rail and bracket assembly 100 of FIGS. 1-8. That is, the equipment rail and bracket assembly 200 includes an equipment rail 210 and a pair of bracket assemblies 220, which are similar to the equipment rail 110 and the bracket assemblies 120. For example, each of the bracket assemblies 220 includes a bracket 221, a clamp 222, and a plurality of fasteners 223, which are similar to the bracket 121, the clamp 122, and the fasteners 123. Additionally, the equipment rail 210 includes a plurality of bracket mounting openings 211 and a plurality of equipment mounting openings 212, which are similar to bracket mounting openings 111 and the equipment mounting openings 112.
However, as best seen in FIGS. 11 and 12, the equipment rail 210 includes a pair of relief cut-outs 213, each of which forms a flexible tongue 214 on the equipment rail 210. The flexible tongue includes at least one of the bracket mounting openings 211.
Additionally, as best seen in FIGS. 13 and 14, each of the bracket assemblies 220 includes a reinforcement plate 224 positioned between the equipment rail 210 and the bracket 221. Preferably, the bracket 221 and the reinforcement plate 224 are separate components, but it is likewise contemplated that the bracket 221 and the reinforcement plate 224 are integrally formed.
As shown in FIGS. 15 and 16, when the equipment rail and bracket assembly 200 is mounted to the cabinet 10, the flexible tongues 214 rotate away from the equipment rail 210 (clockwise in FIG. 15 and counterclockwise in FIG. 16) to accommodate the angled front-to-back beams 12, which prevents the equipment rail 210 from bowing.
Additionally, as shown in FIG. 17, when equipment is mounted to the equipment rail 210, the weight of the equipment causes the flexible tongue 214 disposed at the bottom of the equipment rail 210 to rotate toward the equipment rail 210 (clockwise in FIG. 17). The reinforcement plate 224 prevents the bracket 221 from rotating through the relief cut-out 213 in the equipment rail 210.
While this invention has been described in conjunction with the exemplary embodiments outlined above, various alternatives, modifications, variations, and/or improvements, whether known or presently unforeseen, may become apparent. Accordingly, the exemplary embodiments of the invention as set forth above are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of the invention.
