Abstract

Le dispositif décrit est utilisé pour verrouiller un corps d'ouverture/fermeture (8) sur un corps (9) dans une position fermée. Le dispositif de verrou comporte au moins un bouton (3) et un élément formant loquet (4) disposé sur le coffre (2) de manière à pouvoir coulisser individuellement. Lorsque le bouton (3) est enfoncé de manière à être rétracté à l'intérieur du coffre, l'élément formant loquet (4) passe d'une position de verrouillage dans laquelle il verrouille le corps d'ouverture/fermeture (8), à une position de déverrouillage dans laquelle l'élément formant loquet (4) est dégagé du corps d'ouverture/fermeture (8). Lorsque le bouton est poussé (3) contre une force de contrainte, le bouton (3) est commuté d'une position initiale dans laquelle il fait saillie vers l'extérieur du coffre, à une position enfoncée dans laquelle le bouton (3) est forcé de se rétracter à l'intérieur du coffre. Le dispositif de verrou comporte des moyens de blocage (5) pour bloquer le bouton (3) dans la position enfoncée et pour libérer le blocage afin de ramener le bouton (3) à la position initiale. La libération du blocage est effectuée en association opérationnelle avec une opération de commutation du corps d'ouverture/fermeture (8) de la position d'ouverture à la position de fermeture.
