  • the extension element is preferably designed to move the coupling part.
  • the extension element is in particular designed to be movable independently of the coupling part. Independent means here that a movement of the extension element cannot be transferred to the coupling part via a connection with the coupling part.
  • the independent movement of the extension member from the coupling part involves the coupling part following a movement of the extension member, for example because the coupling part is biased towards the extension member by a spring.
  • the extension element is designed in the axial direction without a form fit to the coupling part.
  • the coupling part can preferably be arranged outside the stator, in particular in the guide of the rotor.
  • the coupling part remains in a coupling position during a movement of the extension element in the second direction.
  • the coupling part In the coupling position, the coupling part is in operative connection with the driver.
  • the coupling part In a decoupling position, the coupling part is out of operative connection with the driver. Due to the fact that the coupling part remains in the coupling position during a movement of the extension element into the withdrawal position, an operative connection remains between the rotor and the driver after the key has been withdrawn. Because the blocking element also blocks movement of the rotor after the key has been removed, movement of the driver is blocked at the same time by the blocking element. As a result, the driver is protected against manipulation.
  • the coupling part can include a coupling element.
  • the coupling element can establish the operative connection between the rotor and the driver.
  • the coupling element can in particular be guided in the guide of the rotor.
  • the coupling element preferably remains in the coupling position, ie in operative connection with the driver.

  • the built-in device includes a front side that faces outwards when installed.
  • the blocking element is arranged between the front side and the coupling part.
  • the blocking element is arranged between the front side and the guide for the coupling part.
  • An energy accumulator in particular a spring, can be provided in order to urge the extension element in the second direction.
  • the energy accumulator does not serve to charge itself if the extension element and the coupling part have different possibilities of movement, for example if the coupling part cannot be operatively connected to the driver due to a current spatial arrangement.
  • the coupling part is preferably designed in several parts with a spring. Mechanical energy can be stored by means of the spring in the case of a momentary spatial arrangement of the clutch part in relation to the driver, which prevents engagement. If the spatial arrangement of the clutch part in relation to the driver permits engagement, then the clutch part engages by means of the spring force of the spring of the clutch part.
  • a torque can be transmitted from the rotor to the coupling part without the extension element transmitting the torque. This makes it possible to design the extension element to be filigree and to save installation space.
  • the extension element can be designed to interact with the coupling part in the direction of rotation without a form fit. This prevents the extension element from transmitting the torque to the coupling part.
  • the extension element can be designed to interact with the coupling part without a form fit.
  • the extension element is preferably designed in one piece.
  • the extension element is preferably angled. It can be provided that a first part of the extension element, which is intended to interact with the key, extends radially further outwards than a second part of the extension element, which is intended to interact with the coupling part.
  • the advantage is that the second part more runs in the middle in order to be able to push the coupling part better. This keeps the dimensions of the coupling part in particular small.
  • the stator includes a base which is designed to be directed inwards and/or towards the aforesaid driver of the locking device in the installed state.
  • the base is preferably designed to face away from a keyway or knob and/or from the front.

In the trigger position, however, the extension member allows movement of the coupling member 92 to the uncoupled position.
  • the driver 103 is connected to the stator 10 via the coupling element 92, the second rotor element 33 and the blocking element 31, so that the driver 103 cannot rotate when the key is removed. This provides good protection against manipulation.
  • a movement of the coupling element 92 in the uncoupling position can, for. B. via a pressure on another sliding element 94 done.
  • the sliding element 94 can, for example Be part of another locking device on the other side of the door.
  • the sliding element 94 is displaced.
  • a further coupling element 95 is pushed into a coupling position with the driver 103 either directly or by tensioning a further spring 96 .
  • the coupling element 92 is shifted from the coupling position into the uncoupling position.
  • FIG 11 Another exemplary embodiment of a coupling part 41 of a locking device 100 according to the invention is shown.
  • the coupling part 41 is the figure 11 used when a knob is used on the other side of the door. The knob is firmly connected to the driver 103. If the key 200 is withdrawn from the locking device 100 according to the invention and the extension element 40 is moved into the withdrawal position, the force of the spring 96 presses the coupling element 92 into the uncoupling position.
  • the built-in device 1 according to the first or the second exemplary embodiment can also be used in other locking devices, for example in a half cylinder, a knob cylinder, a furniture cylinder or a padlock.
  • the coupling part 41 is missing in the installation device 1 according to the invention.
  • locking devices according to the invention can be provided in which the driver 103 is rigidly attached to the rotor 30 .
  • the driver 103 can also serve as a bolt itself, z. B. in a furniture lock.
  • the driver 103 and the insert 105 can be formed in one piece with each other.
  • the stator insert element 13 and the stator body 11 can be designed in one piece. It is also conceivable that the shell 14 is missing and the stator body is fastened directly in the closing device housing 101 .
  • the actuator moves the blocking element 51 back into the blocking position. This can be provided in particular for knob cylinders.
  • the blocking element 51 can alternatively be designed in the form of a plunger.
  • a preferably bistable magnet can be used as an actuator.
  • the plunger may be spring loaded in one direction, preferably away from the magnet.
  • Elements of the first embodiment can be implemented in the second embodiment and vice versa.
  • the second exemplary embodiment can comprise a coil as the transmission device 44 or the first exemplary embodiment can comprise contact elements as the transmission device 44 .
  • the rotor elements 32, 33 of the first embodiment may be fixed together as in the second embodiment.
  • the extension member 40 of the first embodiment and the second Embodiment can be interchanged.
  • the axial fixing of the first rotor element 32 with respect to the stator can take place in accordance with the first or second exemplary embodiment.
  • the installation device 1 according to the invention can be used in a switching element housing, not shown. In this way, a switching element is obtained which can only trigger a switching process if the user has electronic authorization.
  • a driver that rotates with the rotor 30 is used, which actuates a switch. Due to the installation device 1 according to the invention, it is not necessary to provide a blocking element recess in the switching element housing itself. Rather, the stator 10 and the switching element housing together form a fixed component.
