Patent

CA 2333140

The invention concerns an electronic barrel comprising a barrel body (12, 14) and a rotary-lock key bit (10), the barrel body comprising at least a rotor (32, 34) having a common axis with the body and the rotary-lock key bit and freely rotating in said body, a clutch part (40, 42) coupled in rotation with the rotor and comprising meshing means co-operating with means matching the key bit so as to drive in rotation said key bit by the rotor by the action of a rotating torque of the key (8), and locking means for preventing the clutch part (40, 42) from being translated when there is no recognition of an identification code transmitted between the key and the barrel, the locking means are further mounted integral in the rotary-lock key bit and the rotor is mobile in translation for thrusting the clutch part towards the key bit when said identification code is recognised.

Barillet électronique comportant un corps de barillet (12, 14) et un panneton (10) de verrouillage rotatif, le corps de barillet comportant au moins un rotor (32, 34) ayant même axe que le corps et le panneton de verrouillage rotatif et libre en rotation dans ce corps, une pièce d'embrayage (40, 42) liée en rotation au rotor et comportant des moyens d'engrènement coopérant avec des moyens complémentaires du panneton de façon à permettre l'entraînement en rotation de ce panneton par le rotor sous l'action d'un couple de rotation de la clef (8), et des moyens de verrouilage pour interdire la translation de la pièce d'embrayage (40, 42) en l'absence de reconnaissance d'un code d'identification transmis entre la clé et le barillet, les moyens de verrouillage sont en outre montés solidairement dans le panneton de verrouillage rotatif et le rotor est mobile en translation pour permettre une poussée de la pièce d'embrayage vers le panneton en cas de reconnaissance dudit code d'identification.
