ABSTRACT:
An improved barricade is composed of two identical, hollow, molded plastic panel units which are bolted together at top hinges. Novel detents lock the barricade in an open position for use. This mechanism allows for folding and storage by pushing the legs together with a substantial force. The panel units incorporate reinforcing ribs on the legs that taper off at their top and cooperate with opposing leg members and a specially shaped hinge section to allow for flat, compact storage. Horizontal panels are flush to the surface of the panel unit for optimum strength and space utilization. Bottom portions of the hollow panel units are filled with sand as a ballast to increase stability. A special mounting bracket is attached next to one of the hinges to support attachments such as flashers.
