CA 2284583
The present invention relates to a locking device with movable indicator (4, 5) for sensing the "door closed" or "door open" position of a dead-bolt, provided with a pivotably journalled rotating cam (2) (securing plate) intended to be moved between open and locked position by the released dead- bolt (8). The invention is characterized in that the rotating cam (2) and the indicator are mutually connected by means of a spring, e.g. a tension spring (1) arranged in closed, locking position to produce a force component in the closing direction of the rotating cam, and upon removal of the dead-bolt (8) from the rotating cam, i.e. when the door is opened by means of the indicator, to be displaced in relation to the centre (3) of rotation of the rotating cam so that a force component is obtained in opening direction and the rotating cam is turned to opening position by a snap action of the spring.
L'invention porte sur un dispositif de fermeture comportant un indicateur mobile (4, 5) de la position "porte fermée" ou "porte ouverte" d'un pêne dormant, et muni d'une came (2) tournante pivotant sur un axe (plaque de sécurité) entraînée entre une position d'ouverture et une position de fermeture lorsque le pêne dormant (8) se relâche. L'invention se caractérise en ce que la came tournante (2) et l'indicateur sont reliés par un ressort (1) sous tension conçu pour exercer en position de fermeture et de blocage une force dans la direction de fermeture de la came, et, lorsque le pêne dormant (8) se sépare de la came, c'est-à-dire lorsque la porte est ouverte à l'aide de l'indicateur, pour se déplacer par rapport au centre (3) de rotation de la came en produisant une force dans la direction d'ouverture amenant la came en position d'ouverture du fait du déclic du ressort.
