  • Unauthorized removal of the lock bolt from the lock case can already be triggered manually by the additional trap is pressed and by - for example, accidentally - the trap is also easily returned to the lock case. A security against unauthorized extension of the lock bolt from the lock case is thus not sufficiently given.

  • the invention is based on the idea not to bring the locking element into operative connection with the slider, but the locking element is brought into operative connection with the lock bolt.
  • the security against unauthorized extension of the lock bolt from the lock case is further increased, for example when the door leaf in which the lock is installed, is open, so that both the case and the additional case are manually accessible.

  • the pulling of the lock bolt into the position which extends beyond the open position into the lock case can be produced by a stroke movement of the slide, and the stroke movement of the slide can preferably be effected by pushing the latch back into the lock case.
  • a spring element can be provided which biases the blocking element against the additional trap, wherein the blocking element can be brought out of the recess by the spring element.

  • the spring element can be designed as a helical compression spring and arranged around the blocking element.
  • Another advantage results from an operative connection between the slide and the lock bolt, which is designed as a sliding guide, and the slotted guide can have a slide introduced in the gate and arranged on the lock bolt sliding guide element. The direction of movement of the slider and the direction of movement of the lock bolt form a right angle to each other, and by the slide guide, the vertical movement of the slider is transferred to the horizontal movement of the lock bolt.

If the slider is slightly raised, then the link guide element enters the link extension, and the lock bolt is pulled by a small way beyond the open position into the lock case. As a result, the frictional engagement between the locking element and the recess in the lock bolt is released, and the locking element can release the lock bolt. Subsequently, the lock bolt can be fully extended out of the lock case.

Abstract

L'invention concerne une serrure (1) dotée d'un boîtier (10), dans lequel un loquet (11) est logé de manière mobile dans une position faisant saillie du boîtier de serrure (10) et dans une position rentrée dans le boîtier de serrure (10). Une targette (12) est logée dans le boîtier de serrure (10) de manière à pouvoir se déplacer dans le sens de la longueur ; le loquet (11) peut être amené à coopérer avec ladite targette, lorsque le loquet (11) est repoussé dans le boîtier de serrure (10). Un pêne dormant (13) coopère avec la targette (12) et peut être déplacé pendant le déplacement de la targette (12) entre une position verrouillée et une position ouverte. Un loquet supplémentaire (14) coopère avec un élément de verrouillage (15), l'élément de verrouillage (15) étant disposé de telle sorte que le pêne dormant (13) est empêché de se déplacer dans la position verrouillée lorsque le loquet (11) ou le loquet supplémentaire (14) est repoussé dans le boîtier de serrure (10). Selon l'invention, l'élément de verrouillage (15) présente une liaison fonctionnelle avec le pêne dormant (13), la liaison fonctionnelle étant formée par un évidement (16) dans le pêne dormant (13), évidement dans lequel l'élément de verrouillage (15) peut être introduit, du fait que le loquet supplémentaire (14) est transféré dans une position faisant saillie du boîtier de serrure (10), l'élément de verrouillage (15) restant dans l'évidement (16) par friction lorsque le loquet supplémentaire (14) est repoussé dans le boîtier de serrure (10).
