Definitions

  • the invention relates to a lock cylinder with a movable core in a housing and pin tumblers for selectively blocking or releasing the movement of the core, with a closing channel for insertion of a key, with at least one projecting into the lock channel core pin and at least one of a spring element against the core pin prestressed housing pin, with aligned in the core and the housing, the core pin and the housing pin receiving bores of Stiftzunnenen, wherein the arranged in the core holes of the Stiftzuiensen each have a stop for supporting the core pins.
  • the pin tumblers are properly moved by means of a key provided with lock notches or the like in such a manner that the parting planes of the core pins and the housing pins are moved to the parting plane of the core and the housing. Subsequently, the core can be rotated relative to the housing.
  • picking method pulses are introduced into the pin tumblers by introducing a picking instrument in the closing channel, whereby the housing pins dive into the holes and thus moved out of the parting plane between the housing and core.
  • one of the holes guided in the closing channel for the pin tumblers has a smaller depth than the other holes.
  • the core pin of one pin tumbler is supported at a different height than the core pins of the other pin tumblers. If a picking instrument is introduced into such a lock cylinder, the pin tumbler supported at the other height prevents the introduction of pulses simultaneously into all pin tumblers. This leaves at least one of the housing pins between the housing and the core of the lock cylinder and prevents unauthorized movement of the core.
  • a disadvantage of the lock cylinder is that the contour formed by the ends of the pin tumblers projecting into the lock channel is predictable.
  • the lock cylinder can be unlocked with a matching for this lock cylinder picking instrument. Furthermore, the smaller depth of a hole leads to a reduction of a closed-secret of the lock cylinder formed by the variety of the core pins, since only a small length is possible for the core pin used in this hole.
  • a lock cylinder has become known in which a safety pin is held with its free end at a different height than the others Pin tumblers.
  • the holder of the safety pin at the intended height is generated by a pressed-in the bore of the core sleeve.
  • the lock cylinder is very complex.
  • the security pin leads to a restriction of the privacy of the lock cylinder.
  • the invention is based on the problem, a lock cylinder of the type mentioned in such a way that it provides the highest possible protection against unauthorized unlocking and a restriction of privacy is avoided.
  • each lock cylinder can be produced with a different contour of the ends of the pin tumblers projecting into the lock channel. As a result, the contour generated by the free ends of the pin tumblers is not apparent even with similar lock cylinders. This leads to a further complication of unauthorized unlocking the lock cylinder according to the invention.
  • the lock cylinder according to the invention is structurally particularly simple if the core arranged in the bore is formed as a stepped bore and the core pin has two cylindrical, separated by the paragraph sections with the stepped bore, different cross-sections.
  • a scanning of the secrecy of the lock cylinder according to the invention to the projecting into the closing channel ends can be easily avoided when vary in length core pins, the dimensions of the sections on both sides of the paragraph.
  • FIG. 1 shows a lock cylinder with a rotatable in a housing 1 core 2.
  • the core 2 is coupled to a cam 3 via a slidable driver 4 and a plurality of pin tumblers 5, 5 'to the housing 1 positively connected.
  • the core 2 has a closing channel 6 for insertion of a key, not shown.
  • the pin tumblers 5, 5 'each have spring elements 7, 7', housing pins 8, 8 'and guided into the lock channel 6 core pins 9, 9' and are in aligned holes 10, 10 ', 11, 11' of the housing 1 and Kerns 2 led.
  • the spring elements 7 are based on in the housing 1 pressed-in plugs 12, 12 'and clamp the housing pins 8, 8' against the core pins 9, 9 'before.
  • the core pins 9, 9 ' are supported in the core 2 in such a way that their free ends projecting into the closing channel 6 have an irregular contour.
  • the stops 13, 13 'of the arranged in the core 2 holes 11, 11' are each arranged at the same height.
  • the shape of the core pins 9, 9 'and the bores 11, 11' in the core 2 are in FIG. 2 in a greatly enlarged view of two adjacent pin tumblers 5, 5 'shown.
  • the core pins 9, 9 'each have a diameter small section 15, 15' protruding into the closing channel 6 and a diameter-large section 16, 16 'opposite the respective housing pin 8, 8'.
  • the sections 15, 15 ', 16, 16' are each designed cylindrical. It can be seen that the holes 11, 11 'are formed in the core 2 as stepped holes. The grading of the stepped holes are formed as the stops 13, 13 'for the paragraphs 14, 14' of the core pins 9, 9 '.
