Abstract:

A vertical door locking system includes a door lock with a deadbolt that moves horizontally, a striker with an upward facing strike opening that vertically receives the deadbolt and a lock controller. The striker includes an electrically operated catch to engage and release the deadbolt. The door lock and striker are mounted opposite each other, one to the vertical door and the other to an adjacent fixed mounting point. The lock controller electrically operates the striker to release the deadbolt and allow it to move vertically out of engagement with the striker for primary access to a secure area and the door lock allows the deadbolt to be retracted horizontally away from the striker for secondary access. A remotely located control system optionally controls the lock controllers of multiple doors and a central office control system is optionally connected to multiple remotely located control systems.
