Abstract

The studded link chain for police road barriers consists of a number of rectilinear arms hinged together and folded up inside a collapsible chest. The number of arms can be varied according to the width of the road to be barred. One end of the chest has a detachable lid containing a pull cord and at least one peg for holding the chain against the side of the road. Each of the arms has a number of studs (3) which are open on at least one side and which come away from the arm if a car or other vehicle is driven over them. This will force the vehicle to stop without endangering the lives of the occupants, because the tips of the studs remain embedded in the tyres causing a puncture.
