The present invention relates to a cabinet, and more particularly to a seismic kit for a dynamic cabinet.
A typical cabinet installation in a data center located in a seismic zone requires that the cabinet be secured to the floor of the facility. The cabinet needs to be secured so it can withstand significant forces not normally witnessed in typical non-seismic installations.
Thus, it is desirable to provide an improved seismic kit designed to be easily installed on a cabinet to secure the cabinet in a seismic zone.
A cabinet installed in a data center is secured to the floor by a seismic kit. The seismic kit includes a bracket and leveling leg clamps. The bracket includes a first member and a second member with the second member extending from the first member. The second member of each bracket is secured to the front frame or the back frame of the cabinet. The first member of each bracket is secured to the floor. The leveling leg clamps are secured to the first member and are positioned around the leveling legs extending from the cabinet. The seismic kit secured to the cabinet eliminates excessive deflection of the cabinet during a seismic event.
The seismic kit 50 of the present invention is installed on cabinets 20 in data centers located in seismic zones. The seismic kit 50 is bolted on the front and back of the cabinet frame which allows for simplicity during the cabinet placement process. The seismic kit 50 also assures a cabinet height flexibility which enables alignment during ganging of multiple cabinets. As described below, once a cabinet is placed in a desired location, the seismic kit 50 is installed on the cabinet and then secured to floor. The seismic kit 50 includes additional bracing to secure the cabinet 20 to eliminate excessive cabinet deflection during a seismic event.
As illustrated in
Each end of the first member 54 includes an exterior leveling foot 60. When the seismic bracket 52 is installed on the cabinet 20, each leveling foot 60 is positioned between the first member 54 and the bottom of the cabinet 20. Each leveling foot 60 is secured via jam nuts 62. The first member 54 also includes semi-circular cutouts 64 with holes 66 surrounding each semi-circular cutout 64. As illustrated and described with respect to
The second member 56 extends upwards from the first member 54 at the center of the first member 54. The second member 56 is perpendicular to the first member 54. The second member 56 includes a plurality of elongated slots 68 for receiving a mounting bolt 70 to secure the seismic bracket 52 to the cabinet frame 22.
As illustrated in
After the seismic brackets 52 are secured, the exterior leveling feet 60 are raised to contact the outermost edges of the cabinet frame 22 (see
As illustrated in
Furthermore, while the preferred embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the teaching of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as limitation.
This application claims priority to U.S. Provisional Application Ser. No. 62/507,959, filed May 18, 2017, the subject matter of which is hereby incorporated by reference in its entirety.
