Abstract: A fortified gate system and locking mechanism which utilizes spring loaded locking mechanisms, triggered by the impact of an object such as a vehicle, to interlock a gate, a brace, and fortified anchoring devices. This interconnected structure forms an energy absorbing, impenetrable barrier. Because the gate system functions as a normal gate until an instance of attempted crashing entry, it provides reasonable accessibility while maintaining a high level of security. The present device also includes a gate anchor and locking system which is operable independent of the direction in which the gate is impacted.

Abstract: A cantilevered sliding gate made up of a number of panels is disclosed. The panels are joined by post-tensioning rods, carried within horizontal members of the gate and extending substantially the length of horizontal members of the gate. During gate assembly, a tensile stress is induced in the post-tensioning means, which stress is transmitted to the horizontal member as a compressive stress. The resulting stress pattern results in a stiffening effect on the gate assembly, permitting lighter-weight construction than previously possible. The gate is mounted on vertical supports for movement in a plane defined by the supports.
