The elongated bolt is adapted to move linearly to engage to and disengage from the door frame. A transmission including an operating wheel translates circular motion of a rotor of the cylinder lock to a linear motion of the elongated bolt. The emergency unlocking mechanism includes a gear arm connected to a handle and adapted to turn the operating wheel when the handle is turned, disengaging the elongated bolt from the door frame.</p> |
