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.

An improved plastic barricade comprising two integrally molded, generally planar panel units hinged together by one or more bolts extending through one or more bolt holes formed in hinge members integrally molded on said panel units, each of said panel units including reinforcing ribs outstanding from the back of the plane of the panel units, wherein: (a) (i) said hinge members extend from the panel units at an angle obtuse to the plane of the panel units, (ii) said reinforcing ribs extend onto said hinge members, and (iii) said reinforcing ribs are shaped and positioned relative to one another and said hinge members so that said panel units may collapse to a closed, storage relationship wherein the planes of the panel units are parallel opposing ones of said reinforcing ribs intermesh in a side-by-side relationship; and (b) said hinge members include detent means which oppose the collapse of the panel units from an open relationship to said closed relationship, said detent means comprising plastic notches and protuberances which cause portions of said hinge members to elastically deform as said panel units are spread to or collapsed from said open relationship.
