Patent ID: 7862252

Claim:
A vehicle barrier system comprising: a first base; a first arm hingably mechanically coupled to the first base; a raising/lowering mechanism in mechanical communication with the first arm; and a first cable in mechanical communication with the first arm, the first cable mechanically coupled to first and second anchors placed on opposite sides of an area through which a vehicle may pass, a second arm hingably mechanically coupled to a second base; and a second cable in mechanical communication with the second arm, the second cable mechanically coupled to the first and second anchors, wherein the first arm comprises a first portion frangibly mechanically coupled to a second portion, and the first and second portions are uncoupled upon application of at least a threshold force to one of the first and second portions, wherein the raising/lowering mechanism moves the first arm and the first cable between a first position and a second position, wherein the second arm and the second cable are moved between a first position and a second position, wherein the first base and first arm are arranged on a side opposite of the area through which a vehicle may pass from the second base and second arm, and wherein the first arm is mechanically coupled to the second arm, and the raising/lowering mechanism moves both the first and second arms.
