Integrated security and emergency lock

摘要

A door locking device for a door cooperating with a door frame includes a cylinder lock and at least one elongated bolt for moving linearly to engage to and disengage from the door frame. A transmission includes an operating wheel for translating circular motion of a rotor of the cylinder lock to a linear motion of the elongated bolt. The transmission includes at least one electromechanical clutch gear that is engagable in response to a trigger signal to enable the circular motion to rotate the operating wheel, and that is disengagable to disable the circular motion from rotating the operating wheel. An emergency unlocking mechanism includes a gear arm that is connected to a handle for turning the operating wheel when the handle is turned, disengaging the elongated bolt from the door frame.
