Abstract
A barricade is provided for use at construction sites, on roadways and highways, and the like, or for crowd control, for example, at the scene of an emergency. The barricade includes an elongated, hollow crossbar member that comprises one or more elongated, hollow interconnecting sections, with each end of the crossbar member mounted in a collapsible A-frame support. The barricade can be collapsed from its fully-assembled, in-use configuration into a compact unit or package which takes up relatively little space so that it can be conveniently transported from place to place.
