Biometric Control Cylinder Lock Adaptor Mechanism

摘要

The present invention proposes a dummy lock barrel shaped to appear as a conventional lock cylinder and which can conventionally be fixed to the door around the bridge-like region below a vertical gap in between the two cylinder halves. A doorknob shaped driving assembly set coaxial to said dummy cylinder's longitudinal axis is arranged to control locking and unlocking of the driving pawl in between two cylinder halves so as to actuate post-barrel mechanisms in a conventional manner. A further control unit is adapted to communicate with said driving assembly to actuate the driver means in the event authorization is granted. Said control unit comprises a biometric sensor for granting access and both said driving means and said control unit are powered by embedded batteries.
