Abstract
A sign-mounting system for mounting a sign to a structure, includes a frame portion mountable to the sign and a mounting portion mountable to the structure. The system can be symmetrical with each side having coupling elements of the frame and mounting portions which include generally circular rims which fit generally concentrically one within the other. Each rim has locking parts of different radius than adjacent portions of that rim, and the locking parts of respective rims engage to resist rotation. The locking parts can be configured so that resistance to rotation occurs at a plurality of orientations. The respective locking parts can be of different arc lengths to provide a limited range of rotation before the locking parts resist rotation, and a spring can bias rotation in one direction. At least one of the coupling elements can be reversible with two opposite-facing rims.
