ABSTRACT:
A vehicle barrier device is installed in a trench in a roadway. An impaler housing sits in a slot of a liner and supports a pivoting member in a slot in its top surface. The pivoting member has an impaling arm on its forward end, a massive counterweight at its rear end, and a pivot between them. One or more pins and an explosive bolt secure the impaling arm to the forward end of the impaler housing. When the device is remotely activated by security personnel, the bolt explodes, freeing the impaling arm. The counterweight is sufficiently massive so that the pivoting member tends to turn about the pivot under the force of gravity, thrusting the impaling arm above the surface of the roadway. The impaling arm projects at an angle toward a vehicle to be stopped, which is impaled by the arms.
