Road marker, temporary barricade or the like

Claim 1

A road marking structure such as a temporary barricade of the like yieldable to traffic impact, comprising a generally rectangular flat base adapted to rest on the ground and having first and second parallel edges and a pair of panels joined respectively to said edges and converging upwardly to meet and be joined together at an apex spaced a substantial height above the ground, said structure being made up of a single sheet of relatively stiff non-metallic material preliminarily prepared to fold along a plurality of fold lines respectively at the apex and at the junctions of said panels with said base edges, said base including an upper base part joined at one base edge with one panel and a lower base part joined at the other base edge with the other panel, said upper base part overlapping the lower base part to give the base as a whole a substantial area of double thickness so as to minimize downward being of said base, and means securing said parts together, at least said top base part providing an upper surface adapted to receive a weight to hold said structure in place and said fold lines providing hinges so that upon impact by a vehicle against one panel, said one panel is capable of yielding to the impact about its hinge with the base and its apex hinge and the other panel is also capable of yielding about its base hinge and the apex hinge, whereby the entire structure is capacitated to collapse as the vehicle passes over the collapsed structure.
