Patent

CA 2265892

A locking device includes a housing or a casing (3) having an opening (8) for the insertion of a lock activating card (6). The locking device includes a cylinder lock (5) which actuates a catch hook, an intermediate member (2) which is connected to the catch hook through the medium of a latch pin (10), and a pin-like latch member (1) that restricts movement of the intermediate member and therewith also movement of the catch hook until a correct card (6) is inserted into the opening. The card (6) includes at least one hole (6a) and the latch pin (1) can move perpendicularly to the card and therewith be received in the hole in said card, wherewith the latching effect of the latch pin is cancelled and the intermediate member is free to move. The latch pin (1), and therewith the card, is held fixed when the catch hook is swung out.

Cette invention concerne un dispositif de verrouillage, lequel comprend une enceinte ou un boîtier (3) qui possède une ouverture (8) permettant d'y insérer une carte d'activation de verrouillage (6). Ce dispositif de verrouillage comprend en outre les éléments suivants: une serrure à barillet (5) qui va actionner un crochet d'arrêt; un élément intermédiare (2) qui est connecté au crochet d'arrêt au moyen d'une goupille de verrouillage (10); et enfin, un élément de verrouillage de type goupille (1) qui va limiter le mouvement de l'élément intermédiaire ainsi que celui de du crochet d'arrêt jusqu'à ce que la bonne carte (6) soit insérée dans l'ouverture. Cette carte (6) comprend au moins un trou (6a), tandis que la goupille de verrouillage (1) peut se déplacer perpendiculairement à la carte et pénétrer dans le trou de cette dernière. Lorsqu'elle pénètre dans le trou, l'effet de verrouillage de ladite goupille est annulé tandis que l'élément intermédiaire peut se déplacer librement. La goupille de verrouillage et la carte sont maintenues en position fixe lorsque le crochet d'arrête bascule vers l'extérieur.
