  • the Fig. 6 shows a side view of the ring.
  • the Fig. 7 shows a cross-sectional view of the ring.
  • the Fig. 8 shows an isometric view of the ring 28 of the Fig. 6 ,
  • the Fig. 9 shows an isometric view of a cut half of the ring 28th
  • the ring has an inner diameter 50 and an outer diameter 52.
  • the ring 28 is rotationally symmetrical about a rotational symmetry axis 62.
  • the ring has an outer peripheral surface 56.
  • a width of the ring in the Fig. 7 is designated by the reference numeral 51.
  • On the half width of the ring is the so-called ring center plane 64.
  • the ring 28 is formed asymmetrically with respect to the ring center plane 64.
  • an outer peripheral surface 56 of the ring 28 is formed asymmetrically.
  • the outer peripheral surface 56 has a portion 58. This is inclined in the illustrated embodiment, approximately at 45 ° to the annular center plane 64.
  • this section 58 should be designed such that it can not catch on a profiled pin or support pin of the lock cylinder.
  • the outer peripheral surface 56 has a concave portion 60.
  • a concave portion 60 may, for example, be provided to allow the advance of the ring 28 in the keyway by means of the clearance provided by it. Due to the lower provided by the concave portion 60 Cross-sectional area of the ring 28 can thus avoid collisions or be provided more space for other security features of a locking device.
  • the Fig. 10 shows the shaft 26 and arranged thereon, identically formed rings 28 and 30. It is shown a plan view, this direction corresponds to that of Fig. 3 ,
  • the shaft 26 extends, as indicated by the arrow 66, transversely to the longitudinal direction 16 of the key and perpendicular to the center plane 36.
  • An outer diameter of the shaft is designated by the reference numeral 54.
  • the inner diameter 50 of the rings 28, 30 is greater than the outer diameter 54 of the shaft 26.
  • a length of the recess parallel to the longitudinal direction 16 is designated by the reference numeral 74.
  • a width of the recess 32 is designated by the reference numeral 76. As already mentioned, the width 76 of the recess 32 is slightly larger than a total width 72 of the rings 28, 30.
  • total width is meant the combined width of the rings 28, 30.
  • the total width 72 is thus two times the width 51.
  • the length 74 of the recess 32 is slightly larger than the outer diameter 52 of the rings 28, 30.
  • the rings 28, 30 are arranged symmetrically with respect to the median plane 36.
  • the rings 28, 30 are thus identical, but arranged in opposite orientations on the shaft 26.
  • a situation results quasi "back to back”. That is, the concave portions 60 face each other. In this way, despite the asymmetrical design of each of the rings with respect to its annular center plane 74 results in a total symmetrical arrangement with respect to the median plane 36th
  • the Fig. 11 again shows an isometric view of the representation of Fig. 10 , From the in the Fig. 10 shown "neutral position" in which the rings 28, 30 are not deflected, shows the Fig. 11 a deflected state in which the ring 30 is deflected in the direction 68 and the ring 28 in the opposite direction 70. As will be explained below, this design state is particularly relevant to safety for a locking device in order to spend it in the release state.
  • the Fig. 12 shows an exploded view of a locking device 80.
  • the locking device 80 has the key 10, as described above in connection with the Fig. 1 to 11 has been described. The same elements are therefore identified by the same reference numerals and will not be explained again.
  • the closing device 80 has a lock cylinder 81.
  • the lock cylinder 81 is a profile cylinder. However, it may also be another form, for example a round cylinder or oval cylinder.
  • the lock cylinder 81 has a housing 82 and a cylinder core 84.
  • the cylinder core 84 is mounted in the housing 82 by means of a snap ring 86.
  • the housing 83 is otherwise provided, for example, with a mounting hole 87 or threaded hole in order to screw the lock cylinder 81 in a door can.
  • the housing 82 and also the cylinder core 84 can have a multiplicity of bores, in each of which locking devices, in particular pin tumblers, are guided in order to interrogate various security features of a key 10. Shown and explained below are only standing in connection with the rings 28 and 30 locking devices, in particular pin tumblers, which interact with the rings 28, 30.
  • the cylinder core 84 has a keyway 88.
  • the key 10 is inserted into this key channel 88. After the key 10 has been fully inserted and all the security features of the key 10 have been polled positively, all of the locking fuses are moved to a position that permits rotation of the cylinder core relative to the housing 82. This is the release state. If the key 10 is not fully inserted or fully withdrawn from the keyway 88, rotation of the cylinder core 81 relative to the housing 82 is not possible. This is called a lock state.
  • a plurality of profile pins 90 are provided which can serve to interrogate recesses 34 in the key shank 14.
  • the rings 28, 30 cooperate a first support pin 92 and a second support pin 94.
  • the support pins 92, 94 are in the cylinder core 84 pressed. They are not movable.
  • the support pins 92, 94 direct a respective ring 28, 30 in the in the Fig. 11 indicated position and support this against a respective locking fuse or Stiftzuiens 104, 106 from.
  • a first locking device or pin tumbler is designated by reference numeral 104. This cooperates with the first support pin 92.
  • the first locking device is indicated schematically and usually has a core pin 96.
  • a housing pin 98 is supported by a spring element 100 or support spring against a support member 102.
  • protrusion of the housing pin 98 into the cylinder core 84 prevents rotation of the cylinder core 84.
  • a contact surface between the core pin 96 and the housing pin 98 is located such that the housing pin 98 does not protrude into the cylinder core 84, including the Core pin 96 does not protrude into the housing 82. In this way, the rotation of the cylinder core 84 relative to the housing 82 is made possible.
  • the second locking device or pin tumbler 106 on the basis of a core pin 98. The remaining elements of this locking device are not shown for reasons of clarity. This second locking device 106 cooperates with the second support pin 94.
  • the Fig. 13 shows an isometric assembled view of the locking device 80.
  • the key 10 is completely inserted into the cylinder core 84.
  • the cylinder core is mounted in the housing mouth 82 by means of the snap ring 86.
  • the Fig. 14 shows a corresponding side view of the assembly view of Fig. 13 , The same elements are identified by the same reference numerals.
  • the Fig. 15 shows a cross-sectional view taken along a line XV-XV of Fig. 14 . Same elements as in the exploded view of Fig. 12 are marked with the same reference numerals and will not be explained again.
  • the closure device 80 is in a release state.
  • the key 10 is fully inserted in the keyway 88.
  • the first support pin 92 deflects the ring 30 and thereby moves the core pin 96.
  • each of the support pins 92 and 94 is arranged at an angle of approximately 45 ° to the keyway.
  • Each of the support pins 92 and 94 has a conical tip which slides along the respective outer peripheral surface 56 of each ring 28, 30 to deflect it as the key 10 is inserted.
  • the support pins 92 and 94 are disposed on opposite sides of the keyway 88. Accordingly, the first pin tumbler 104 and the second pin tumbler 106 are also disposed on opposite sides of the keyway 88.
  • the Fig. 16a shows a view of the keyway 88.
  • the viewing direction is in the Fig. 13 shown.
  • the key 10 is cut out here except for the shaft 26 and the rings 28, 30.
  • the outer circumferential surface 56 is asymmetrical with respect to a respective annular middle plane 64.
  • each keyway 88 in opposite surfaces has a complementary cross-sectional profile to interrogate this asymmetric outer peripheral cross-section of each ring 28,30. It can thus be seen that the ring 28 initially at a neutral position in the Fig. 16a "up" offset in the keyway 88 is guided.
  • the ring 30 is correspondingly "down” offset guided by the keyway 88.
  • the respective asymmetrical outer peripheral cross sections fit into the complementary profile cross sections 109 and 110.
  • the complementary profile cross sections 109, 110 extend as longitudinal grooves completely through the keyway 88 and guide the rings during insertion of the key 10 to a rear end of the keyway 88, in the rings 28, 30 are deflected by the support pins 92 and 94.
  • the Fig. 16b shows a view of the key channel 88.
  • the locking device 80 In the in the Fig. 16b illustrated position, the locking device 80 is in a release state. Like in the Fig. 16b can be seen, the rings are then deflected here in corresponding opposite directions away from their respective complementary profile cross sections 109, 110. In this way, a labyrinth is provided, through which the rings 28, 30 must be performed as movable elements to reach the release state. It is thus imperative that the rings 28, 30 can be moved separately or independently on the shaft 26. In this way, the safety of the illustrated locking device 80 can be significantly increased. Furthermore, a security of the key 10 against unauthorized reworking or copies is significantly increased, because the rings 28, 30 must be known and reproduced as separately movable elements.
  • FIGS. 17 and 18 once again show a clear view of the involved in the release state and in cooperation with the rings 28 and 30 elements of the lock cylinder 81.
  • Clearly recognizable is again the deflection of the rings 28 and 30 in the opposite direction. These are deflected by the about the angle 108, in particular an angle of 45 °, relative to the keyway 88 and a longitudinal extension of the shaft 26 inclined support pins 92 and 94. These deflect each one of the rings 28, 30 and support it against a respective Kernux 96, 99 from.
  • each of the rings 28, 30 is thus pushed between an associated support pin and core pin.
  • the ring 30 is slid between the support pin 92 and the core pin 96.
  • the ring 28 is pushed between the support pin 94 and the core pin 99. Due to the fixed arrangement of the support pins 92, 94 while a respective ring 29, 30 is deflected and moves a corresponding core pin 96, 99, so that an associated locking fuse 104, 106 is moved to the release state. As already stated above, in particular the movement of the rings 28, 30 takes place in mutually opposite directions.
