Patent number: 8112924Abstract: An expandable support assembly for hanging a sign on a host structure subject to dimensional changes over time includes a pair of elongate arms pivotally attached together at a crossing point, a connector pivotally attaching the elongate arms together and permitting the arms to rotate relative to each other, four anchors, and a panel attached to the connector for supporting the sign. Each anchor engages a respective longitudinal portion of one of the arms such that the connector is positioned between two anchors with respect to each arm. The anchors are movable along the arms for securing the expandable support assembly to the host structure. 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.Type: GrantFiled: May 18, 2009Date of Patent: February 14, 2012Inventor: Vincent A. Longobardo
