Abstract

The invention relates to a key- or pushbutton-actuable panic lock, in which a main lock case (1) is provided with a driving-rod slide (8) which is rigidly connected in terms of drive to driving rods (2, 3) and which is secured against displacement via a blocking device on the housing (7) of the main lock when the bolt (5) is extended, wherein the blocking device becomes inactivated by means of key-actuated unlocking. With the aim of specifying a lock with is actuable by pushbutton and which has a high level of security against the driving rods being pushed back, it is provided that the blocking device has a pawl (14) which is charged into the locking position thereof in the main lock case (1) by spring force and which can be forced back by means of a lever (12) which is actuable by a follower arm and a cylinder.

Description

technical field [0001] The invention relates to an emergency lock according to the preamble of claim 1 . Background technique [0002] Known from DE 3520862 C2 and DE 3537786 C2 is a lock construction solution in which the main lock box comprises a bolt and a dead bolt and a transmission rod slide which is connected to a shaft protruding from the housing of the main lock box. Transmission rod drive connection. The drive lever is assigned a secondary lock box and / or a latch element which can be moved into or out of the lock engagement by the drive lever. The transmission rod slide is provided with a locking device which prevents displacement of the transmission rod slide by the transmission rod in the locked position of the bolt. Thus, unlocking of the lock should be prevented if a potential thief tries to move the transmission rod or levers with the aid of a tool. Without a locking device, the pin of the main lock box and all other latch elements and / or secondary locks on...
