  • Locking system is understood here to mean a system with mechanical elements which allows or blocks access to or access to an object, depending on whether or not there is an authorization a door knob, by pressing a door handle or similar means, or automated, enable or prevent by means of suitable drive means, etc.
  • Locking devices of this type have a housing which can be fixedly connected to an object (for example a door) and a housing movable relative to the housing
  • the actuator is rotatable in many cases in the housing and is therefore often called 'rotor'.
  • the actuator is with

  • Locking element can be actuated.
  • the actuator itself can serve as a bar.
  • the actuator is often operated with a key or directly by hand. It can also be moved by an electric drive relative to the housing.
  • Mechanical locking and unlocking mechanisms are based, for example, on the interaction of tumbler / Gegenzuienssfaren the lock cylinder with Codtechniksbohronne on a matching key.
  • the mechatronic, electronically controlled locking is based on a data transmission between an electronic module associated with the closing device and an electronic module belonging to the key.
  • This data transmission can take place by contact - for example by means of electrical contacts on the key and lock - or without contact - for example by means of electromagnetic induction.
  • Data can be transmitted in one or both directions.
  • In the electronic module of the closing device and / or in the electronic module of the key is checked based on the transmitted data, whether the inserted key is authorized to access. If this is the case, then an electric drive of the closing device is activated, which electronically controlled moves a blocking element such that it releases the closing device.
  • Mechatronic or combined mechanical / mechatronic locking and unlocking mechanisms offer the possibility of implementing additional security features in comparison to purely mechanical mechanisms and, depending on this, allow a simpler reprogramming of an access regime. But they also have disadvantages in terms of safety (under certain circumstances, an unlocking electric motor caused by externally induced currents power consumption, susceptibility to failure and wear (the device has many parts), complexity and cost and space requirements.

Le dispositif de fermeture se trouve dans un état verrouillé lorsque l'élément de blocage et/ou d'accouplement est dans sa première position. Selon l'invention, il est prévu un élément de commande (5) qui peut être déplacé entre deux positions par l'action d'entraînement d'un moteur piézoélectrique, sachant que dans une première position, il ne permet pas à l'élément (3) de blocage et/ou d'accouplement de prendre sa première position ou sa deuxième position, et que dans une deuxième position, il permet un déplacement de l'élément (3) de blocage et/ou d'accouplement dans la première ou la deuxième position.
