Abstract
A wind resistant sign for display purposes includes a base and a resilient panel having a base portion supported by the base for extending outwardly from the base in a direction perpendicular to the base, the panel being thin and of such resilience and strength as to undergo bending deflection responsive to wind forces. First and second oppositely disposed mounting members of the base are clamped together by screw and nut fasteners to define between the members a throat for receiving the panel base portion. The throat opens upwardly on opposite faces of the panel in smoothly outwardly diverging relationship to the panel with radius of curvature much less than the natural bending radius of curvature of the panel to provide a strain-relieving support on opposite faces of the panel when undergoing bending deflection.
