  • coupling arrangements which lock or release a shaft of the actuating element against the door to be opened or another stationary object in a rotationally fixed manner. With a confirmed authorization to open the door, the shaft of the actuator is then unlocked so that the actuator can be rotated and a lock can be operated. Otherwise, the actuator can not be rotated due to the obstruction against the door or the other object.

  • the reverse movement from a dome position to the uncoupling position for example, when the pin members 74, 76 due
  • the slider element 68 is moved in the axial direction, namely in the negative X direction, in the case of a large friction in an adjacent element.
  • the slider element 68 moves in the axial direction relative to the switching element 62 and also relative to the adjusting disc 72.
  • the second spring element 80 is then compressed. In this now the applied force is stored. If the pin elements 74, 76 are then released, the second spring element 80 relaxes and displaces the adjusting disk 72 in the negative X direction and thus also the pin elements 74, 76 in the uncoupling position.
  • Fig. 4 shows the coupling assembly 40, wherein in the Fig. 3 assembled elements are assembled. Identical elements are identified by the same reference numerals and will therefore not be explained again. For reasons of clarity, only the electrical connection 50, the drive device 60 and the pin elements 74, 76 are designated.
  • the coupling arrangement has a housing 112.
  • the housing 112 is configured as a cylindrical sleeve member extending along a longitudinal axis 126. In the longitudinal direction, the housing 112 is divided into two parts. It thus has a first housing part 114 and a second housing part 116.
  • the housing can basically have any shape, in particular it can also be a section of a knob shaft 32 or above a section of a housing of a knob 22, 28.
  • the two housing parts 114 and 116 can be assembled, which simplifies assembly of the clutch assembly 40.
  • a first section 120 of defined cross-section over which a ring 118 can be slid with a corresponding cross-section to hold the two housing halves 114 and 116 together and at the same time serve as sliding bearings.
  • a further section 124 of defined cross-section may be provided over which a Correspondingly configured cover element 122 can be pushed. This can also serve to hold the housing halves 114, 116 and / or as a sliding bearing.
  • the coupling assembly 40 on an end face 128, which forms a coupling surface 36.
  • two recesses 130, 132 are provided, through which the pin members 74, 76 can pass. In a dome position, thus, a portion 134 of the pin member 74 and a portion 136 of the pin member 76 protrude from the end face 128.
  • a drill protection 154 is shown. Such a drill protection 154 can usually be formed as a cone. The tip of the cone then points in the negative X-direction, ie away from the drive device 60. The drive device 60 is fixed against rotation on the housing 112.
  • Fig. 5b the clutch assembly 40 is shown in a uncoupled position.
  • the pin elements 74, 76 are retracted, so that the sections 134, 136 no longer protrude from the end face 128.
  • the coupling arrangement 40 can then be released or the housing 112 can then rotate freely relative to an adjacent element 16 or a further shaft segment 42 to 48.
  • the Fig. 6 shows an embodiment of a lock cylinder 10 with the coupling assembly 40 in the assembled state.
  • the remaining elements of the lock cylinder 10 have exploded. Identical elements are identified by the same reference numerals and will therefore not be explained again.
  • the lock cylinder housing 30 may be formed in particular as a profile cylinder and has a threaded bore 160, with which, for example, the lock cylinder by means of a screw relative to a lock 14 and the door 12 can be attached.
  • the closing element 16 is designed as a closing nose and has Dome recesses 167, 168, in which the pin members 74, 76 can engage with the closing element 16 for rotationally fixed coupling of the clutch assembly 40.
  • the pin members 74, 76 can engage with the closing element 16 for rotationally fixed coupling of the clutch assembly 40.
  • two of a total of six distributed over the circumference dome openings 167, 168 Of course, for example, eight or ten recesses can be distributed over the circumference.
  • ring members 164, 165 may be provided to seal, for example, the clutch assembly 40 to the closure member 16 and / or to slide.
