Abstract

L'invention concerne des serrures de sécurité à commande électromagnétique réalisées selon la technique des aimants de maintien. Le principe de base réside dans le fait qu'un électroaimant influe sur un élément de commande et sur un élément de blocage de telle sorte que, lorsqu'une impulsion d'ouverture est émise, le verrou est retiré. L'objectif de l'invention est de simplifier, et de rendre plus sûres de telles serrures, et d'en élargir le champ d'utilisation. Selon l'invention, le verrou (7) déplace un curseur (5) pourvu d'une denture, qui entraîne un disque de blocage (2) pourvu d'un canal pour tige tournante (2a). Le disque de blocage (2) est accouplé, par l'intermédiaire d'un ressort (12), à un disque de commande (3) qui présente un canal pour tige tournante (3a) angulairement décalé. Le disque de commande (3) comporte un induit (13a) qui, lors du mouvement de commande du verrou (7), peut être maintenu par un électroaimant (13) solidaire du boîtier. Lors du processus d'ouverture, les deux canaux sont alignés avec l'axe de la serrure, de sorte que la voie de la tige tournante est libre.
