Abstract

La présente invention concerne un dispositif de verrouillage (5), qui est utilisé pour une porte (9B) qui est commutée entre un état fermé et un état ouvert par rapport à une partie ouverte du côté d'un corps principal et qui est toujours sous tension dans la direction d'ouverture, ledit dispositif comprenant un support (2) qui entre en prise avec une partie réceptrice (55a), ou se détache de celle-ci, lorsque la porte est fermée. Le dispositif est équipé d'un boîtier (1) qui est placé sur la porte et qui soutient le support (2) de manière coulissante, d'un verrou (3) qui est soutenu en haut du support et peut pivoter vers le haut ou vers le bas contre la force de mise sous tension, d'une plaque de régulation (35) qui peut coulisser sur le support (2) et rentrer en contact avec le verrou (3), ou se séparer de celui-ci, d'un moyen de mise sous tension qui met le verrou sous tension (3) dans une direction pour entrer en prise avec une partie réceptrice (8d) au travers de la plaque de régulation (35) et du support (2), et de mécanismes de cames (39, P) réglés selon un historique de fonctionnement pour commander le coulissement de la plaque de régulation (35) afin de maintenir le verrou (3) en prise avec la partie réceptrice (8d) maintenue par la plaque de régulation (35) grâce à la porte poussée depuis la direction d'ouverture vers la direction de fermeture contre la force de mise sous tension, et pour séparer la plaque de régulation (35) du verrou (3) afin de libérer le verrou en poussant de nouveau la porte dans la direction de fermeture. L'invention concerne ainsi un dispositif de verrouillage qui présente une grande résistance, une excellente efficacité opérationnelle et un très bon aspect.
