CA 2217410

A keyless entry system for use with conventional locksets is provided. The system employs a battery operated motor and a gear train mounted on the inside of a door. The motor and gear train rotate the inside handle of the lockset in the same manner as a user would rotate the handle to unlatch the door. Misalignments between the gear train and the lockset are accommodated by a pawl which connects the gear train to the connecting shaft between the lockset's inside and outside door handles. The electric motor is activated by a control system responsive to a RF signal generated by a transmitter pendant carried by the user. The RF signal includes a user code, and the control system has a learning mode and an operating mode, with the learning mode serving to record a list of one or more authorized user codes and the operating mode employing that list to determine if the door should be unlatched in response to a particular user code.

Système sans clé pour serrures classiques. Le système fonctionne à l'aide d'un moteur à piles et d'un train d'engrenages logés à l'intérieur d'une porte. Le moteur et le train d'engrenage font tourner la poignée intérieure de la serrure comme le ferait une personne qui voudrait ouvrir la porte. Les désalignements entre le train d'engrenage et la serrure sont compensés par un cliquet qui relie le train d'engrenage à la tige carré sur laquelle sont fixées les poignées intérieure et extérieure. Le moteur électrique est actionné par un système de commande qui détecte un signal RF généré par un émetteur miniature porté par un utilisateur. Le signal RF comprend un code d'usager et le système de commande possède un mode d'apprentissage, qui permet d'enregistrer un seul ou toute une liste de codes d'usager autorisés, et un mode de fonctionnement, qui se sert de cette liste de codes pour déterminer s'il doit ou non déverrouiller la porte en réponse à un code d'usager particulier.
