Embodiment Construction

[0022] as from Figure 1 to Figure 5 It can be seen that the shown exemplary embodiment of the double door according to the invention comprises a moving leaf 3 , a fixed leaf 5 and a locking device 1 . In the exemplary embodiment shown, the locking device 1 comprises a lock box 10 with a latch 14 and a locking element, which in the exemplary embodiment shown is designed as a locking element 18 . 1 . The lock secures the latch 14 in the shown extended locked state against transfer to the retracted locked state. In addition, the locking device 1 includes a buckle box 20 with a sealing plate 22 . In the extended locking state, the latch 14 engages at least partially in a recess 24 of the closure 22 . An actuating device 30 in the catch box 20 actuates the unlocking element 16 guided in the lock bolt 14 , which cancels the locking of the lock bolt 14 in the lock box 10 , and which releases the lock bolt 16 in order to implement the emergency escape function. 14 transitions from...

Abstract

A closure assembly for a double-leaf door comprises: a lock box having a latch and a locking member, wherein the locking member fixes the latch in an extended locked state to prevent it from transferring to a retracted locked state; a buckle box with closure flap, wherein the latch is at least partially embedded in a recessed portion of the closure flap, and the actuating device in the buckle boxsteers an unlocking element guided in the latch for achieving the emergency escape function, the unlocking element revokes the locking of the latch in the lock box and transfers the latch from the extended locked state to the retracted locked state in which the latch releases the closure flap. The actuating device is configured as a deflection lever having a base lever and an actuating lever thatare deflectable about the deflection axis, and the gap width between the actuating lever and the latch in the extended locked state can be adjusted based on the positional change of the actuating lever. The invention also relates to a double-leaf door having such a closure assembly.

Description

technical field [0001] The invention relates to a locking device for a double-leaf door and to a corresponding double-leaf door having such a locking device. Background technique [0002] Even in the locked state, a double-leaf door comprising a moving fan and a fixed fan and a locking device with full escape function must be able to be opened safely when the fixed fan is opened first. In order to prevent the protruding and locked latch of the moving fan from tilting in the sealing plate of the fixed fan, the latch passes through a special mechanism in the buckle box of the fixed fan when operating the emergency escape lever and / or handle of the fixed fan Transitions from the extended locked position into the retracted locked position. Previously, the locking of the latch was unlocked by actuating an unlocking element, which is usually integrated in the latch. Since such doors have different gap sizes depending on the production, the distance between the closing metal plat...
