Definitions

  • the invention relates to an electromechanical programmable lock and its operating system.
  • a locking system based on a programmable, electronic key can be implemented either as centralized or decentralized or as a combination thereof.
  • a centralized system consists of an electricity supply and telecommunications network, electrically operated lock bodies, electronic key reading devices, elec- tronic keys, generally containing only a code, programmable control units and backup batteries.
  • a centralized system provides good properties, but is expensive to implement especially in an old building, in which no provision has been made for the cabling required by the system.
  • a decentralized system generally makes an independent opening decision in the lock control unit on the basis of information programmed in the key.
  • the power supply of the system has typically been implemented by a power source feeding the lock control unit and/or a backup battery.
  • the power supply of a decentralized system can also be implemented by a battery in the key.
  • the maintenance of the batteries of the locks and keys is problematic, because the draining of the batter ⁇ ies prevents opening the lock or they leave the lock in the open position.
  • the key includes a memory element, which can be read and iden ⁇ tified by the reading circuit in the lock. If the lock recognizes the electric identifier of the key, the lock opens either by turning the key set in the lock or by the opera ⁇ tion of an electric opening mechanism.
  • a locking code has been saved in the key.
  • the key also includes a small battery, by which the key code can be sent to the lock.
  • Another exemplary solution of the use of an electric key identifier is known from the application WO 00/68536. However, both systems require an external energy source for carrying out the electric recognition and electric opening of the lock.
  • Publication DE 19918817 discloses a procedure, in which the key has been pro ⁇ vided with an arrangement creating electricity.
  • the electricity is produced by means of a mass moving in the key, which operates an electric generator.
  • the mass in the key moves when the person is moving, thereby creating a small elec ⁇ tric current.
  • the electricity produced is loaded to a battery in the key.
  • the energy of the battery is used in sending the code of the key to the lock.
  • a lock which is independent of an external energy source and at least partly elec ⁇ trically operated, can also be implemented by using the piezoelectric phenome ⁇ non.
  • An arrangement, in which piezoelectric elements have been installed in the body of the lock, is known from the patent US 6 437 684. Inserting the key in the lock and turning it in the lock creates a deformation in the piezoelements, which creates an electric current. This current is utilized in the management of the lock ⁇ ing.
  • the problem with piezoelectric elements is a low pro ⁇ duction of electricity in a static or slow oscillating motion. Therefore, using a piezo element in an application in which higher electric power is required, requires mak ⁇ ing the piezo element to oscillate at a high frequency in one way or another. Achieving high-frequency oscillation complicates such lock structures, in which piezoelectric elements are utilized.
  • the objective of the invention is to provide a new lock and locking method, by which an electromechanic, programmable lock system can be implemented with ⁇ out a separate, electric power source.
  • a lock arrangement in which me ⁇ chanical power transmission has been arranged from a tumable lock cylinder to an electric generator tumably fastened to the lock body, the turning angle of which depends on the torque transmitted by it.
  • electric current is first produced by an electric generator to the electric key identification system of the lock. Then the electrical load of the generator does not produce a high torque.
  • the output ar ⁇ rangement of the generator is changed so that the torque transmitted by the gen ⁇ erator increases strongly.
  • Turning the key then also causes the turning of the body of the electric generator, as a result of which the mechanical detent is removed from the opening path of the lock. After this, the lock opens fully mechanically by turning the key further.
  • the invention has the advantage that an electric lock system can be implemented without a separate electric actuator and the storage of electric energy required by it.
  • the invention has the advantage that electric identification can be used in the lock, which enables the use of more versatile protection arrangements than a conventional mechanical locking system.
  • a further advantage of the invention is the fact that electric energy is required only for the identification and acceptance of the key and the coupling arrangements of the terminals of the generator.
  • Yet another advantage of the invention is easy electric programmability of the lock and the key, which enables changing the locking system easily.
  • An additional advantage of the invention is the fact that the key bit can be smooth, or only one projection or groove is required in it to enable drawing the door open by the key.
  • Another additional advantage of the invention is the fact that the lock can be opened mechanically by turning the key, and no electric energy is required for opening it.
  • the electromechanical lock according to the invention is characterized in that the electric energy required by the electric identification has been produced from the movement of the key by an electromagnetic generator, and that the difference be ⁇ tween the torque transmitted by the loaded and unloaded electromagnetic genera ⁇ tor has been arranged either to open the lock or to bring it to the blocking state.
  • the electromechanical locking method according to the invention is characterized in that the electric energy required by the electric identification of the key is pro ⁇ bonusing by the movement of the key by means of an electromagnetic generator, and that the difference between the torque of the loaded and unloaded electromagnetic generator is used either to open the lock or to bring it to the blocking state.
  • the basic idea of the invention is the following: Electrical identification and accep ⁇ tance of the key and mechanical opening motion of the lock bolt are both utilized in the lock.
  • the key is identified and accepted electrically, but the motion of the bolt is achieved mechanically by turning the key.
  • the key turns sufficiently for moving the bolt only if the key has been identified.
  • an unaccepted key turns freely around in the lock body without a mechanical connection to the lock bolt.
  • the electric energy required for the identification and acceptance is produced in the lock by an electromagnetic generator, the rotor of which is turned by turning the key.
  • the motion of the key to the rotor of the generator is transmitted from the lock cylinder by a gear system.
  • the body of a direct-current generator has been installed in the lock body so that the direct-current generator can be turned around its longitudinal axis. If the control unit of the lock finds that the key turned in the lock is not allowed to open the lock, the control unit changes the coupling of the output of the direct-current generator in a way that the torque of the rotor is mini ⁇ mized. For example, the terminals of the generator can be disconnected. In this case, the body of the generator does not turn from its rest position, and the detent bar of the lock cylinder collides with the detent in the lock body. Alternatively, the key turns round in the lock without a mechanical connection to the bolt. The situation changes if the control unit of the lock finds that the key turned in the lock is such that the lock may be opened by it.
  • the control unit of the lock changes the coupling of the output of the direct-current generator in a way that the torque of the rotor increases strongly.
  • the output of the generator can be shorted, for example.
  • the torque produced by the key and directed to the generator grows so high that it exceeds the moment caused by the fastening of the body of the direct-current generator, which resists the turning of the body of the direct-current generator.
  • the body of the direct- current generator then turns so that it moves the detent bar in the lock to a position in which it does not prevent turning the lock cylinder by the key to a position in which the bolt is drawn into the lock.
  • the key is connected to a freely turning lock cylinder, which is further connected to the bolt.
