发明名称 Folding scaffold sign
摘要 A folding scaffold sign. The sign is constructed of a special honeycombed plastic material in which two sign panels are provided, separated by a fold line. The bottom corners of the panels are provided with metal legs inserted through openings forming the honeycomb structure. The legs are retained in the openings by elasticity and friction of the plastic memory material and the sign can be used as a triangular free-standing sign supported upon a floor surface, ground or the like. The sign may further be used as a cover for an existing conventional post-supported sign by placing the folded sign thereover and folding the panels together and retaining the legs in secured condition by a retaining chain. The folded-over sign may be stored in the same presentation when the panels are folded over against one another in superimposed position.
