Embodiment Construction

[0020] figure 1 Shown is the main lock box 1 of the multiple locking mechanism for actuating the bolt 4 and the main bolt or bolt 5 by means of transmission rods 2 , 3 protruding from the main lock box 1 . Other latch elements not shown here. These latch elements, not shown here, can likewise be latch elements supported in the secondary lock box or latch elements directly on the transmission rods 2, 3 and movable together with said transmission rods, said In the locked position, the latch element is assigned in a stationary manner to a latch insert mounted in the frame. The drive rods 2 , 3 are guided displaceably on flanged rails 6 .

[0021] Inside the housing 7 of the master lock box 1 , the transmission rods 2 , 3 are drivingly connected via a transmission rod slide 8 and are simultaneously coupled with the master lock drive. Lock sleeve 9 has sleeve arm 10 ( figure 2 and 2a ), the sleeve arm stops on the corner 11 of the transmission rod slider 8 when pivoting and m...

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. Background technique [0002] A panic lock is known from EP 0619409, which is push-button-operated. In this case, the locking can be released by actuating a button on the inside of the house. In this case, a locking pawl is provided here, which locks the transmission lever slide in the pre-locked latch position and actuates the key into engagement or disengagement via the lock cylinder. For this purpose, the pawl is mounted in the region of the lock cylinder, which reduces the available installation space. [0003] Lock construction solutions are known from DE 3520862 C2 and DE 3537786 C2, wherein the main lock box comprises a bolt and a dead bolt and a transmission rod slide which is connected with a transmission rod protruding from the housing of the main lock box Driver connection. The drive lever is equipped with secondary lock boxes and / or latch elements which can be moved into and out of the lock en...
