Patent

CA 2395703

An electronic locking system (10) comprises a cylinder (14) housed within and rotatable with respect to a shell (16). A key (18) has a power supply (28). At least one of the key (18) and the cylinder (14) is capable of generating a signal when the key (18) is electrically connected with the cylinder (14). An electrically powered locking mechanism is housed within the cylinder (14) and includes a lock member (12) moveable between an open position and a locked position. The lock member (12) in the locked position interferes with movement of the cylinder (14). A power source (28) is connected to the locking mechanism in response to the signal. The locking mechanism allows movement of the lock member (12) from the locked position to the open position in response to the signal so that the cylinder (14) may be rotated within the shell (16). The cylinder (14) further includes an interfering member that resists movement of the locking member (12). In addition, a biasing mechanism urges the cylinder (14) toward a home position when the cylinder (14) is rotated away from the home position.

L'invention concerne un système de verrouillage électronique (10). Ce système comprend un cylindre (14) logé, en vue de sa rotation, à l'intérieur d'un stator (16). Une clé (18) présente une alimentation électrique (28). Au moins un élément parmi la clé (18) et le cylindre (14) peut générer un signal. Un mécanisme de verrouillage électrique est logé à l'intérieur du cylindre (14) et comprend un élément de verrouillage (12) pouvant se déplacer entre une position ouverte et une position verrouillée. L'élément de verrouillage (12) dans la position verrouillée interfère avec le déplacement du cylindre (14). Une source électrique (28) est reliée au mécanisme de verrouillage en réponse au signal. Le mécanisme de verrouillage permet à l'élément de verrouillage (12) de se déplacer entre une position verrouillée et une position ouverte, de telle sorte que le cylindre (14) peut tourner. Ce dernier (14) comprend en outre un élément d'interférence (190) qui s'oppose au déplacement de l'élément de verrouillage (12). En outre, un mécanisme de décalage pousse en force le cylindre (14) vers une position initiale lorsque ce dernier (14) tourne à partir de sa position initiale.
