  • the locking element 31 When the rotor 30 is unlocked relative to the stator 10, the locking element 31 is initially located in the locking element recess 15. The locking element 31 is guided in the rotor 30 in this case. In addition, the blocking element 31 is in contact with the first contact surfaces 16 of the stator elements 12 . As a result, the blocking element 31 is centered. This position of the blocking element 31 is referred to as the rest position. In the rest position, the blocking element 31 is preferably arranged at a distance from the blocking element 51 .
  • the control device 53 controls the actuator 52 .
  • the actuator 52 designed as an electric motor rotates the blocking element 51 into the release position in which the recess 54 is opposite the blocking element 31 . If the rotor 30 is now started to rotate using the key 200, the blocking element 31 slides along one of the first contact surfaces 16 into the second position, in which the blocking element 31 in the recess 54 engages. Here, the springs 34 are stretched. The blocking element 31 moves in the direction of movement 70.
  • the first contact surfaces 16 form an acute angle ⁇ with the direction of movement 70 of the blocking element 31 (see Fig. figure 8 ).
  • stator elements 12 remain in the first position. This is made possible by the fact that the spring elements 18 exert a greater force on the stator element 12, along which the blocking element 31 slides, than the springs 34 exert on the blocking element 31.
  • the rotor 30 is now freely rotatable.
  • the locking element 31 slides along that of the first contact surfaces 16 into which the locking element 31 is rotated.
  • the locking element 31 is surrounded by the first contact surfaces 16 in both directions of rotation, so that rotation in both directions when it contacts at least one of the first contact surfaces 16 allows the locking element 31 to move into the second position.
  • the blocking element recess 15 is surrounded on both sides by at least a first stator element 12, 12a and a second stator element 12, 12b (see Fig. figure 7 ).
  • the stator 10 has a second contact surface 17 which leaves the blocking element 31 in the first position.
  • the second contact surface 17 is functionally used when the user is not authorized to unlock the door.
  • the second contact surfaces are formed in the stator insert element 13 . If the blocking element 31 is in the rest position, the second contact surfaces 17 are spaced further away from the blocking element 31 than the first contact surfaces 16.
  • the second contact surfaces 17 are preferably also inclined, but in the opposite direction to the first contact surfaces 16 in relation to the direction of movement 70 of the locking element 31.
  • the second contact surfaces 17 thus form an obtuse angle ⁇ to the direction of movement 70 of the locking element 31 (see figure 8 ).
  • the blocking element 31 seen along the axis of rotation of the blocking element 51 and/or the rotor axis 35, has a cross section which has the shape of a preferably symmetrical trapezium tapering in the direction of the blocking element 51.
  • the legs of this trapezoid form head surfaces 60 outwardly in relation to the blocking element 31.
  • the head surface 60 and the corresponding contact surface 17 are designed to be inclined relative to the direction of movement of the blocking element 31.
  • the sequence is as follows.
  • the locking element 31 is initially in the rest position.
  • a key 200 without a locking authorization is inserted into the keyway 36 .
  • the electronic data exchange shows that there is no authorization to unlock the door. Therefore, the actuator 52 is not activated and the blocking element 51 remains in a blocking position, in which the recess 54 does not face the locking element 31, as in FIG figure 4 and 5 shown. Rather, an outer circumference of the blocking element 51 lies opposite the blocking element 31 .
  • the blocking element 31 If the rotor 30 is rotated, the blocking element 31 tries to slide along the first contact surface 16 . However, this does not succeed since the blocking element 31 stands on an outer circumference of the blocking element 31 . Thus, the blocking element 31 cannot be pushed into the second position against the force of the springs 34 .
  • stator element 12 which is located in the direction of rotation of the blocking element 31 , is pushed back by the blocking element 31 against the force of the spring 18 until the blocking element 31 rests against the second contact surface 17 .
  • the stator element 12 is now in the second position.
  • the head surface 60 of the blocking element 31 comes into contact with the corresponding second contact surface 17 opposite one of the legs of the trapezium.
  • stator element 12 or the stator elements 12 have been moved back in the direction of rotation against the force of a spring element 18 .
  • the spring element 18 presses the stator element 12 against the locking element 31 as the rotor 30 rotates further.
  • the contact surface 17 is designed in such a way that the contact surface 17 holds the blocking element 31 in the first position. Thus, the rotor 30 remains blocked by the blocking element 31 so that the door cannot be unlocked.
  • Every second contact surface 17 corresponds to a respective head surface 60 of the blocking element 31 facing the head surface 60.
  • the surface 60 and the corresponding contact surface 17 are designed in such a way that the contact surface 17 is located between the surface 60 and the blocking element 51 when the blocking element 31 is on the contact surface 17 is applied.
  • the blocking element 31 slides away from the blocking element 51 counter to the direction of movement 70 . This is achieved by the slope of the second contact surface 17.
  • the blocking element 31 can slide along with the head surface 60 on the second contact surface 17 .
  • the blocking element 31 and the blocking element 51 can thus be spaced apart from one another when they are in contact with the second contact surface 17 .
  • the forces that act on the blocking element 31 in the event of further attempted rotation of the rotor 30 are diverted into the second contact surface 17 .
  • a contributing factor here is that the head surfaces 60 correspond to the second contact surfaces and the blocking element 31 thus lies flat against the second contact surface.
  • this makes it possible to mount the blocking element 51 on one side.
  • FIG 5 the blocking element recess is provided with the reference number 15 .
  • 6 shows the arrangement of figure 5 Seen from an end face of the blocking element 31, only without blocking element 51.
  • the stator elements 12 are in the second position.
  • FIG 7 are the same elements as in figure 6 presented in a different perspective. Additionally are in figure 7 the spring elements 18 shown and on the left side a spring seat 65 of the stator 10 for receiving the spring elements 18, while the spring seat 65 is not shown on the right side.
  • the blocking element 31 is surrounded by the second contact surfaces 17 in both directions of rotation, so that the rotation in both directions of rotation when it rests against one of the second contact surfaces 17 leaves the blocking element 31 in the first position.
  • the first contact surfaces 16 are closer to the blocking element 31 than the second contact surfaces 17.
  • the second contact surfaces 17 protrude more into the blocking element recess 15 than the first contact surfaces 16.
  • the first and the second contact surfaces 16, 17 are arranged axially one behind the other in the direction of the rotor axis 35.
  • four first contact surfaces 16 are provided, for example, with two first contact surfaces 16 being provided in each direction of rotation of the rotor 30 .
  • two first stator elements 12a are provided on one side of the locking element recess 15 and two second stator elements 12b are provided on the other side of the locking element recess 15 .
  • the blocking element 31 extends in the axial direction in relation to the rotor axis 35 in such a way that the blocking element 31 can come into contact with both the first contact surface 16 and the second contact surface 17 .
  • the locking element 31 is formed in one piece.
  • first contact sections 64 of the blocking element 31, which are used to contact the first contact surfaces 16, are rigidly connected to the head surfaces 60, which are used to contact the second contact surfaces 17.
  • the top surfaces 60 serve here as second contact sections.
  • the first and the second abutment sections 60, 64 are rigidly connected to the third abutment section 63 of the locking element, which serves to abut in the recess 54.
  • the first contact section 64 is adapted to the first contact surface 16, ie the blocking element 31 in the first contact section 64, for example as an in Can be designed towards blocking element 51 widening trapezoid. As a result, the blocking element 31 can slide flatly along the first contact surface 16 .
  • the four stator elements 12, for example, are outwardly delimited on one side by a guide surface 62 of the stator insert element 13 during the movement between the first and the second position.
  • the stator elements 12 are delimited on the inside by a guide surface, not shown, of the stator body 11 .

  • the shell 14 serves to fasten the stator insert body 13 in the stator body 11 .
  • the first rotor element 32 has a larger diameter than the second rotor element 33.
  • the stator elements 12 and the stator insert body 13 are arranged in the portion of the stator 10 which surrounds the second rotor element 33. Due to the small diameter of the second rotor element 33, it is possible to provide the first and the second system sections 16, 17 in the stator 10.
  • a peripheral projection 43 of the second rotor element 33 serves as a stop for the second rotor element 33 on the stator 10.
  • the projection 43 is preferably designed in one piece with the second rotor element 33. As a result, the second rotor element 33 is fixed axially towards the front side 37 .
  • the first rotor element 32 can be inserted into the stator 10 from the front side 37 .
  • the first rotor element 32 is fixed axially towards the driver 103 by an end face 66 facing the second rotor element 33 .

  • the latching element 61 is formed, for example, by means of a spring-loaded latching lug. i.e. the rotor 30 can overcome the detent 61 when rotating, so that the function of the rotor 30 is maintained.
  • An annular projection 22 is formed by means of, in particular, half-shell-like parts whose inner surfaces 26 facing one another interact with the key 200 in the manner of a bayonet catch. The parts are inserted into a peripheral groove 45 of the first rotor element 32 . Outwardly projecting projections 25 of the annular Projection 22 fix the parts of the projection 22 in the stator body 11 in their relative position to each other and to the stator body 11.
