WIPO Patent Application WO/2011/129521
Kind Code:

Abstract:
The present invention relates to a barricade for vehicles that prevents excessive loads from being exerted on iron spikes by inducing the iron spikes to collapse in the travelling direction of the vehicle after piercing tires, thereby improving the effect of preventing vehicles from escaping by means of the iron spikes cutting portions of the tires, and ensuring the smooth operation of the iron spikes. The disclosed barricade for vehicles comprises: a housing having a plurality of long holes defined on the top surface thereof and separated from one another; a plurality of iron spikes installed in the plurality of long holes, respectively, and rotatably folded so as to project or not project upward from the housing; a supporting shaft installed in the housing to rotatably support the plurality of iron spikes; and an actuator installed in the housing to actuate the rotation of the iron spikes, wherein the iron spikes are installed such that a portion thereof projecting upward from the housing is designed to rotate and collapse in the travelling path of tires when the tires, having the portion of the spikes embedded therein, pass over the rotational center of the portion of the spikes.
