ABSTRACT:
The hollow plastic barricade comprises a pair of identical, integral, hollow, hinged-together barricade frame members, each frame member having first and second hinge sections located at respective upper corners thereof. The first hinge section on one frame member cooperates with the second hinge section on the other frame member to form two hinges between the frame members. Each frame member comprises two hollow, spaced apart side frame portions with a leg at the bottom of each side portion, an upper hollow panel, a middle hollow panel and a lower hollow sandbag bar, all extending between the side frame portions. The middle panel is spaced beneath the upper panel and the hollow sandbag bar is spaced beneath the middle panel and is spaced above the bottom of the legs a distance which will permit the barricade to be placed over uneven terrain and still be supported by the legs. At least one of the panels is adapted to receive indicia thereon. The first and second hinge sections each include at least one arcuately extending hook-like projection with a bore extending transversely through the sides thereof and with an end surface adapted to engage and bear against a top edge of the other frame member. Each frame member has an opening for placing particulate ballast material, such as sand, in the frame member, and the barricade further comprises two pins each of which is received through a pair of adjacent projections extending from respective ones of the frame members.
