Abstract
A sign mounting system for adjustably mounting a sign such as a sheet or panel to an associated structure includes an elongated frame portion mountable to the sign and a mounting element for mounting the frame to the structure. The frame portion includes a central runner and side walls extending generally transversely from the runner. The side walls are spaced from one another and in conjunction with the runner define a track. The side walls each terminate in a lip spaced from the runner a first predetermined distance. The mounting element includes a cam having first and second sliding surfaces spaced from one another a distance substantially equal to the first predetermined distance, and first and second camming surfaces spaced from one another a distance greater than the first predetermined distance. The mounting element is pivotal between a first adjusting position in which the sliding surfaces are adjacent the runner and lips, and a second locking position in which the camming surfaces engage and lock between the runner and lips.
