<p>Electro-mechanical cylinder lock, comprising a lock casing 1 and in the latter a rotatable lock cylinder 2 and locking devices, which normally prevent turning of the lock cylinder 2 in relation to the lock casing 1 and which, by means of a key 7 for the lock, can be displaced into a position allowing the lock cylinder 2 to be released and turned, the lock key 7 in addition comprising devices 11 for transmitting an electronic code and the lock correspondingly comprising devices 13, 14 for receiving and recognising the key code so that, when the correct code occurs, the said devices 13, 14 are designed to allow the lock to be opened mechanically by means of the key 7. The lock has at least one lock washer 9, 9', the key opening 9b, 9b' of which is formed so that a turn of the key does not immediately act mechanically on the lock washer 9, 9', the lock being provided with electrical operating devices 17, 17' that can be activated by means of the key electronic code, which devices, in the activated condition, are designed to turn at least the said one lock washer 9, 9' with the key into a prerequisite position for opening of the lock mechanism. <IMAGE></p> |
