Embodiment Construction

[0022] as from Figures 1 to 5As can be seen in the figure, the illustrated 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 locking cover 12 and a bolt 14 as well as a locking mechanism, which is designed as a locking element 16.1 in the exemplary embodiment shown. The locking mechanism positions the deadbolt 14 in the illustrated extended locked state against transfer to the retracted locked state. In addition, the locking device 1 also includes a buckle box 30 with a blocking plate 32 . In the extended locking state, the locking bolt 14 engages at least partially in the recess 34 of the closure plate 32 . In order to implement the emergency escape function, the operating device 40 in the buckle box 30 operates an unlocking element 20 guided in the bolt 14 (the unlocking element removes the locking of the bolt 14...

Abstract

The invention relates to a locking arrangement (1) for a two-leaf door and a two-leaf door having the locking arrangement. The locking arrangement comprises a lock box (10) with a lock cap (12) and alock bolt (14) and a blocking mechanism which holds the lock bolt (14 ) in an excluded state against a transfer to an enclosed state, and a mating box (30) with a closing plate (32), wherein the lockbolt (14) in the excluded state at least partially engages in a recess (34) of the closing plate (32); in order to execute an emergency escape function, an actuating device (40) in the mating box (30)actuates an unlocking element (20) guided in the lock bolt (14) which unlocks the lock bolt (14) in the lock box, and the actuating device (40) transfers the lock bolt from the excluded state to theenclosed state in which the lock bolt (14) releases the closing plate (32). According to the locking arrangement, the unlocking element (20) has an adjustment device accessible from the lock cap (12)which adjusts a gap width (S) in the excluded state between the actuation device (40) and an actuation region (26.2) of the unlocking element.

Description

technical field [0001] The invention relates to a locking device for a double-leaf door and to a corresponding double-leaf door having the locking device. Background technique [0002] Double-leaf doors with moving and fixed fans as well as locking devices with full escape function must also be able to be reliably opened in the locked state when the fixed fan is opened first. In order to prevent the protruding locking bolt of the moving fan from being skewed in the sealing plate of the fixed fan, the bolt passes through the special lock box (Gegenkasten) of the fixed fan when operating the handle and / or emergency escape lever of the fixed fan. The mechanism moves from an extended locked position to a retracted locked position. First, the locking mechanism of the bolt is unlocked by actuating an unlocking element, which is usually integrated in the bolt. Since such doors have different gap dimensions due to manufacturing conditions, the distance between the closing (metal) ...
