Abstract

La serrure électronique décrite (20) est pourvue d'un organe (90) donnant la priorité à la combinaison manuelle pour permettre l'ouverture d'une serrure à la fois par un moyen électronique (100) et par un moyen manuel (34, 90). La serrure électronique (20) comprend un mécanisme (40) de désengagement du verrou (17), qui permet l'ouverture de la serrure (20) soit par le mode électronique soit par le mode manuel. Le mode électronique et le mode manuel permettent tous deux d'ouvrir la serrure par actionnement du mécanisme (40) de désengagement du verrou. Le mécanisme (40) de désengagement du verrou est constitué par un assemblage à plusieurs composants (42, 50, 60) pouvant fonctionner comme une seule unité ou par rapport à chaque composant selon le mode d'ouverture choisi. L'utilisation du mode électronique s'effectue par l'intermédiaire de composants électroniques, tels que notamment des commutateurs sensibles à la pression (102), des circuits logiques (106) et une carte de montage de circuits (103). Une combinaison électronique est générée, retenue et utilisable avec les composants électroniques pour permettre l'ouverture de la serrure.
