Abstract: A base is provided for use with warning signs and the like. A metal structural framework is fitted to the underside of an elastomeric body in the form of a monolithic slab. Forces from the sign panel are transmitted through the structural framework, which includes a plurality of outwardly radiating legs. Forces are transmitted to the ends of the legs, which preferably are fitted with outwardly extending feet. Force loadings are transmitted through the structural framework rather than the elastomeric body, which provide a ballast for the structural framework.

Abstract: A collapsible signaling device bearing a pair of opposed message panels is convertible between a display configuration and a compact linear storage configuration. The message panels are joined together at spaced apart points along their periphery using spacers to form a pocket having an internal cavity. A mast is insertable within the pocket and is joined to the panel members at its upper end. A pair of struts of spring material are joined at one end to the upper end of the mast and are joined at their lower ends to a slider member which is slidably movable with respect to the mast. As the slider member is advanced toward the upper end of the mast, the struts are outwardly bowed imparting outwardly directed tension to the periphery of the message panels.
