ABSTRACT:
A panic exit door lock includes a cover (20) mounted to an outer side (10b) of a door (10). A sliding member (34) is slideably received in the cover (20) and operably connected to a latch (12). A handle (24) is pivotably mounted to the cover (20) and operably connected to the sliding member (34) such that rotation of the handle (24) causes sliding of the sliding member (34) to move the latch between an extended position and a retracted position. A limiting member (32) is pivotably received in the cover (20) between a blocking position not allowing movement of the sliding member (34) and a release position allowing movement of the sliding member (34). An inner lock core (54) and an outer lock core (270) are respectively mounted to an inner side (10a) and the outer side (10b) of the door (10). Either of the inner and outer lock cores (54, 270) can be rotated by a key to move the limiting member (32) between the blocking position and the release position.
