发明名称 Gate anchor and system and method of locking a gate
摘要 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.
