Abstract: A method and storage and locking arrangement for storing keys to locks and controlling the use of keys. The storage and locking arrangement consists of a closed box or a similar storage unit, a central lock and its key, as well as a number of auxiliary locks, each having its designated key. The locks are arranged in a closed box or similar storage unit so that they can be unlocked using keys from the outside of the box. The central lock is arranged to control the operation of the auxiliary locks so that when the central lock is locked, it prevents the keys to the auxiliary locks from being removed from their respective locks, and once the central lock is unlocked, it can be used to select the operation of any single auxiliary lock at a time using the corresponding key so that the key to the auxiliary lock can be removed from the auxiliary lock.

Abstract: An electromechanical cylinder lock-key-combination includes a key having a mechanical locking code and a device for storing an electronic code and sending it into the lock. A lock body encloses a turnable lock cylinder and a locking mechanism which normally prevents turning of the lock cylinder with regard to the lock body and which can be moved by the key into a releasing position allowing turning of the lock cylinder.

Abstract: An electromechanical cylinder lock-key-combination which includes a key of the lock having a mechanical locking code and means for storing an electronic code and sending it into the lock, a lock body enclosing a turnable lock cylinder and locking means which normally prevent turning of the lock cylinder with regard to the lock body and which can be moved by means of the key of the lock into a releasing position allowing turning of the lock cylinder, at least one special locking disc with which the key is not in direct mechanical force transmission connection, identification and control means for receiving and identifying the electronic code from the key, and electric operating means with coupling means attached thereto and having a free position and a coupling position in which they are arranged to couple said at least one special locking disc with the turning movement of the key for opening the lock, whereby when there is a match with the correct electronic code of the key said identification and control mea

Abstract: An electromechanical actuator comprises a body element and an elongated interaction element. One of the elements includes an electromagnet and the other ferromagnetic material or permanent magnet. The elements are arranged with respect to each other so that a rotational motion may be imparted to the interaction element by a magnetic field created by the electromagnet. The interaction element is rotatable between two rotational positions by changing the polarity of energization of the electromagnet. At one rotational position the interaction element is displaceable by an external force applied to one end in a direction along its rotation axis. The interaction element cooperates with the body element in a manner such that they together define the range of axial movement of the interaction element.

Abstract: An electromechanical cylinder lock includes a lock body and a turnable lock cylinder and a locking mechanism inside the lock body. The locking mechanism normally prevents turning of the lock cylinder relative to the lock body and can be moved by a key of the lock to a releasing position allowing turning of the lock cylinder. The key for the lock includes a transmitter for transmitting an electronic code and the lock correspondingly includes a receiver for receiving and identifying the code of the key. When the receiver detects the correct code the receiver enables mechanical opening of the lock by the key. The lock includes 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. The lock also includes a coupling element for coupling the locking disc to the turning movement of the key.

Abstract: The invention relates to an electromechanical lock arrangement including a lock body (1), which is provided with a cylinder lock mechanism (3) having a key channel (17) and a turnable lock cylinder (16), a dead bolt (2) movable back and forth by means of the cylinder lock mechanism (3), electrically operable latch means (7) for controlling the operation of the dead bolt (2) and a logic unit (8) for controlling said electrically operable latch means (7). The arrangement includes further a key unit (4) having a mechanical key member (4a) for operating the cylinder lock mechanism (3) as well as means for supplying electric power and means for sending a coded electrical signal into said logic unit (8). At the reception of a correct code the logic unit (8) is arranged to switch current to said electrically operable latch means (7) so that they allow said dead bolt (2) to be moved from its protruding locking position into its withdrawn releasing position in the lock body (1).

Abstract: A door lock comprises a reciprocatingly movable lock bolt and means for locking the lock bolt in a protruding position, for keeping the lock bolt in a withdrawn position and for operating the lock bolt either with a handle or the like or with a key operated mechanism. There is also a lock function selector for selecting a desired type of functional capacity for the lock. The lock function selector has three different setting positions, of which each determines a specific type of functional capacity for the lock. There is a setting member, preferably in a hidden position when the lock is mounted in a door, by means of which setting member the setting of the lock function selector can be restricted in order to further determine the types of function obtainable by the lock.

Abstract: A cylinder lock comprising a cylinder housing, a cylinder turnable therein, and in the cylinder, a plurality of locking discs turnable by the key of the lock. The locking discs are arranged in separated relation from each other by immovable intermediate walls in the cylinder. Thus, each locking disc has its own firmly fixed turning space.

Abstract: A method for the production of a cylinder lock with a fixed cylinder housing, a turnable cylinder therein and a number of locking discs turnable by the key of the lock; a locking bar operable in the radial direction by the locking discs locks the cylinder to the cylinder housing. The method provides the lock cylinder with locking discs without peripheral recesses allowing the opening of the lock; the locking discs are turned with a key member into an opening position defined by the key member; and a joint groove corresponding to the form of the locking bar is machined into the set of locking discs at the position of the locking bar. Each of the locking discs is provided at the right position with a peripheral recess allowing the opening of the lock. The operation can be repeated with other key members for providing the lock mechanism with a desired number of opening combinations usuable in mastered locking systems.
