Safety roadwork warning triangle - reversibly anchored in base-plate which lies flat with triangle if overturned

摘要

The objective is provision of a warning sign, indicating the presence of roadworks or other obstructions, which does not itself constitute a danger to traffic, being safely run over in the event of being knocked down or blown over. The triangular panel is set in a base plate, which incorporates recesses of such a dimension that when the triangle is overturned the surface of the base plate forms a single plane with the triangle, and causes no damage to any vehicle which may run over it. The bottom edge of the triangular panel is enlarged, having sufficient thickness to locate against the road surface and maintain the panel normally upright.
