Patent ID: 8615948

Claim:
A seismic bracket for supporting the ends of suspended ceiling grid runners from a wall at the perimeter of the ceiling comprising a stamped sheet metal body, the body having a horizontally extending portion and a vertically extending portion, the vertically extending portion, in its installed position, rising above the top of a standard grid runner a distance at least 1Â½ times the height of such standard grid runner, the vertically extending portion having two sections generally coextensive with each other in the vertical direction and integrally joined with each other at discrete land locations separated by apertures along a vertical line substantially equal in length to the vertical extent of the vertically extending portion, a first section being integral with and generally coplanar with the horizontally extending portion and a second section arranged to be in a vertical plane that intersects a vertical plane occupied by the horizontally extending portion and the first section of the vertically extending portion, the horizontally extending portion including an elongated slot being arranged to support a grid runner with a screw assembled through the horizontally extending portion elongated slot and driven into the grid runner in a manner enabling the grid runner to move longitudinally a limited distance relative to the vertically extending portion, the second section of the vertically extending portion having a flat configuration and an aperture for securing the bracket to the wall at a location substantially above the grid tee, the first and second sections being separated at their lower ends by a lower aperture on said vertical line, said lower aperture being downwardly open whereby a lower portion of said second section is adapted to be installed behind a wall angle while a lower portion of said first section is disposed at the level of and directly in front of said wall angle, the first and second sections being joined at locations on said vertical line above their lower ends along a distance that is greater than the vertical extent of said lower aperture.
