Abstract:
An electromechanical cylinder lock and key arrangement comprising:a key that embodies a mechanical combination and includes a code transmitter for transmitting an electronic code, anda lock includinga lock body,a turnable lock cylinder and a locking mechanism inside the lock body, the locking mechanism comprising a locking means which normally prevents turning of the lock cylinder relative to the lock body and which can be moved by means of the key into a releasing position allowing turning of the lock cylinder,a receiver means for receiving and identifying the electronic code transmitted by the code-transmitter of the key and comparing the received code with a stored code so that if the received code matches the stored code said receiver means enables mechanical opening of the lock by means of the key,a locking disc with a key opening which is so designed that the turning of the key does not directly act mechanically on the locking disc, andan electric operating means to be activated by means of the electronic code from the key, the electric operating means including a coupling means having a first state in which the coupling means allows the key to turn relative to the locking disc and a second state in which the coupling means couples turning movement of the key to the locking disc so that said locking disc turns with the key to a position required for opening the locking mechanism.
