Abstract

L'invention concerne un dispositif de serrure doté d'un pêne qui coopère avec et se dégage d'une section de logement de verrou à l'état de porte fermée ; lorsque la porte est poussée dans le sens allant de l'ouverture vers la fermeture, le pêne coopère avec la section de logement et un état de porte fermée peut être maintenu ; et en repoussant la porte dans le même sens, ladite coopération est libérée et la porte peut pivoter dans le sens de l'ouverture. Le dispositif de serrure comporte : un boîtier qui porte le pêne ; un moyen de sollicitation qui sollicite le pêne dans le sens tendant à le faire dépasser du boîtier ; un organe déclencheur qui passe d'une position normale de repos n'appliquant aucune charge au pêne à une position de travail pivotée sous l'effet de la contrainte engendrée lors d'un heurt sur une section de gâche du corps principal et qui déplace le pêne en s'opposant à l'effort de sollicitation ; un moyen de ressort qui ramène l'organe déclencheur à la position de repos ; et un mécanisme de verrou qui, chaque fois que l'organe déclencheur passe de la position de repos à la position de travail, peut basculer alternativement entre un état solidarisé qui maintient l'état où le pêne est déplacé en s'opposant à l'effort de sollicitation et un état désolidarisé qui met fin audit maintien.
