Problems solved by technology

[0004] A disadvantage of known tongue locks is that they have a relatively large space requirement for the mechanism
Especially the mounting of the locking lever on the housing requires additional installation space
Equally disadvantageous is the complex assembly, since the mechanism is partly supported on the housing
The combination of the entire working mode of the mechanism can also be carried out in the housing, thus increasing the complexity of assembly

Embodiment Construction

[0039] Figure 1 to Figure 4 A first embodiment of the tongue lock according to the invention is shown. This tongue lock has a mechanism provided with a tongue 30 . The tongue 30 of this embodiment has both a tongue 36 and a tongue slider 34 . In this case, the tongue 36 is fastened in a receptacle on the tongue slider 34 , for example by means of screws.

[0040] Tongue slider 34 and thus the entire tongue 30 can be translated in Figure 1 to Figure 4 Movement to the left and right. Furthermore, the tongue slide 34 is loaded with a spring force by the spring element 38 , so that the spring force of the spring element 38 must be overcome when the tongue 30 is moved to the right. Spring force 38 in Figure 1 to Figure 4 Pull the tongue 30 back to the stop position to the left. As is customary in tongue locks, the tongue 36 is configured with a sliding ramp, so that when the door is closed the entire tongue 30 can be moved to the right against the spring force of the sprin...

Abstract

The latchbolt lock (10) has a housing (20) and a trap latch (30) comprising an engaging bevel (32) for engaging a nut arm (52) of a lever follower (50) to translationally move the trap latch against spring force. A locking lever (60) is rotatably supported at the trap latch to block the translational motion of the trap latch at two detent positions. A retainer (40) is formed such that a rotatable driver (110) of an actuator (100) e.g. lock cylinder and toilet door follower, is unlocked by the rotation of the locking lever and translationally moves the trap latch when the actuator is received in the retainer.

Description

technical field [0001] The present invention relates to a tongue lock for a door. Background technique [0002] Cam locks for doors are basically known and are described, for example, in DE 198 39 043 . This known tongue lock is used to equip doors with a latch. The tongue lock has a housing within which a deadbolt mechanism is arranged. Such a bolt mechanism of the known bolt lock is provided with a tongue which is arranged in a housing in a translational movement against a spring force. In addition, such a cam lock has a receptacle for the lock cylinder and a handle receptacle for receiving the door handle. In known tongues, it is generally possible to move the tongue against the spring force both by means of the door handle and by means of the lock cylinder. This makes it possible to open the door by means of the door handle as well as by means of a key, so that the door can also be opened from the side of the door which does not have a door handle. [0003] Furtherm...
