Abstract
A pressure-release latch for releasably locking closed a door panel on the frame to which the door panel is hingedly connected. The latch has a base and a latch bolt rotatable between a closed position that locks the door panel closed and an open position that allows the door to swing open. A latch bolt actuator connected to the latch bolt rotates the latch bolt between the closed and open positions from outside the door panel, locks the latch bolt in the closed position, and automatically unlocks and moves the latch bolt to the open position when a predetermined opening force is applied to the latch bolt. A calibration mechanism adjusts the magnitude of the predetermined opening force required to automatically unlock the latch.
