A security barrier device for stopping, redirecting or disabling hostile vehicles.
Patent Application of David Hartigan A security barrier device for stopping, redirecting or disabling hostile vehicles. One or more barrier devices are placed on the ground to prevent the access of vehicles. Should a hostile vehicle strike the barrier device with sufficient momentum, the striking edge of the vehicle contacts the concave central section (10), forcing the striking edge upwards, thus lifting the front wheels off the ground. With sufficient further momentum, the vehicle's striking edge will continue upwards until it contacts the underside of the top section of the barrier device (12) forcing said top section away and thus lifting the leading edge of the base (14) off the ground, causing said base to strike the underside of the hostile vehicle, lifting the front of the vehicle further off the ground, rendering it immobile. The geometric shape of said base will make the combined vehicle/ barrier device unstable, rolling the vehicle to one side, and off its wheels preventing any further movement. -12
