    Abstract: Safety latch means for locking a vertically movable door against accidental descent. A latch carried by the door has a notch which normally freely receives a guide angle flange extending along the path of door movement. The latch turns or cocks to cause the notch to bind upon the flange and lock the door against accidental descent in response to the failure of the cable.
