Abstract
An improved vault door having a daylock and a relock mechanism is disclosed. The door is selectively locked and unlocked within a frame of the vault by operating a pair of combination locks mounted to the door front to slide a lock bar mounted to the rear of the door. The daylock mechanism includes a spring biased member which engages a cavity in a daylock extension attached to the lock. This engagement holds the lock bar in the unlocked position so the door may be swung within the frame without the lock bar impacting the frame. A keylock mounted in the front of the door may be turned to withdraw the member from the cavity so the lock bar can be slid to secure the door in the frame. The relock mechanism includes a pivotably mounted bar held in a horizontal position by a pin mounted to an attack plate that is displaceably mounted to a mounting plate on the rear of the door. When a drill augers through the door and impacts the attack plate, the plate moves rearwardly to move the pin out of engagement with the pivotable bar. The bar then rotates to a position where it blocks the withdrawal of the lock bar to the unlocked position regardless of any operation of the combination locks.
