Patent ID: 8112924

Claim:
An expandable support assembly for hanging a sign on a host structure subject to dimensional changes over time, the support assembly comprising: a) a pair of elongate arms pivotally attached together at a crossing point; b) a connector pivotally attaching the elongate arms together at the crossing point and permitting the arms to rotate relative to each other; c) four anchors, each one of which engages a respective longitudinal portion of one of the arms such that the connector is positioned between two anchors with respect to each arm, and each one of which is movable along the one arm for securing the expandable support assembly to the host structure; d) a panel attached to the connector for supporting the sign; and e) wherein the arms are adapted to permit movement of the anchors along the arms and the connector is adapted to permit relative rotation of the arms in response to dimensional changes over time of the host structure, wherein each anchor is adapted to move longitudinally without affecting the position of the panel with respect to the connector.
