ABSTRACT:
A collapsible barricade comprising a rigid cross-member coupled by an elastic joint to at least one pair of rigid legs. The elastic joint is developed by a flexible, elastic, resilient connecting member which is attached at one end to the cross-member and at the other end to the rigid leg in a manner such that the formed elastic joint is capable of stretching under stress to allow the pair of legs and attached cross-member to deform from a sturdy configuration when subjected to an impact by a vehicle or other moving object. The collapsible barricade can then be restored to its sturdy condition by merely repositioning or reattaching the connecting members to the respective legs and cross-member and by repositioning the deformed structure to its original configuration.
