Push bar locking mechanism with rapid unlocking

摘要

A push bar locking mechanism for locking and unlocking a door also comprising a push bar arranged integral to a bar frame such that the push bar can be moved relative to the bar frame. An elongated link is integral to the push bar and bar frame and is movable in response to the push bar movement relative to the bar frame. The movement of the elongated link causes a door locking mechanism to move between a locked and unlocked position. An electromagnetic locking mechanism is included that can be changed between an energized and de-energized state by an electrical signal, wherein the electrical locking mechanism generates a magnetic field when energized. An armature is also included in proximity to the electromagnetic locking mechanism and the elongated link. The armature prevents movement of the elongated link when the electromagnetic locking mechanism is energized.
