A lock, which is designed as a panic lock for a door of freezing room, includes a chassis (1, 2) and a latch bolt (3), which is displaceably guided into the chassis, impinged upon by a spring force in the direction of extension and beveled at least on one side. A two-part nut is rotationally mounted inside the lock. The inside part is able to be actuated by an inner operating lever, including an inner catch which enables the latch bolt (3) to be actuated at least in the insertion direction. An outer nut part (7), which can be actuated by an outer operating lever, includes an outer catch (10) enabling the latch bolt (3) to be actuated in the insertion and extraction direction. When the operating lever is not actuated, structure (15, 16) places the catch (10) of the nut part (7) in a neutral position in which the catch (10) is not in contact with the latch bolt (3). Structure (21-24) are also provided for locking the outer catch (10) in the neutral position thereof. |

1. A panic lock for a door of a refrigeration room or freezer room, the lock comprising:
a chassis; a latch bolt displaceably guided relative to the chassis, the latch bolt being biased by spring force in an extension direction and the latch bolt being bevelled on at least one side, wherein the latch bolt forms a dead bolt, and a first extension position is provided, in which only the latching function is effective, and a second extension position reaching beyond the first extension position is provided as a dead bolt function; a rotatably mounted and divided hub, of which an inner hub part actuatable via an inner operating lever comprises an inner catch, with which the latch bolt can be actuated at least in a retraction direction, and of which the outer hub part actuatable via an outer operating lever comprises an outer catch, with which the latch bolt can be actuated in the retraction and extension direction; neutral positioning means which, given a non-actuation of the operating levers, bring the catches of the hub parts into a neutral position, in which the catches are disengaged from the latch bolt; and locking means for locking the outward catch in the neutral position from outwards. |
