Definitions

  • the invention relates to a rotary lock cylinder for a Security lock, with a cylinder housing and an in this rotatably mounted rotor and with several pin tumblers, the one to enable the rotor to rotate Classify key channel of the rotor to be inserted are.
  • Rotary lock cylinders of this type have been known for a long time and proven in practice.
  • To unlock security to increase such rotary lock cylinder are Various measures known to a person skilled in the art. Straighten this especially against unauthorized unlocking attempts where with an instrument inserted into the key channel the pin tumblers are classified by vibration.
  • the known measures against such attempts cause that the time required to classify the pin tumblers is significant is increased. This has the consequence that such unauthorized Attempts are usually canceled.
  • DE-U-9 307 547 is a generic rotary lock cylinder known. This has core pins on, which are designed as telescopic pins. The exterior The pin part is at its tip with grooves or Slits. When trying to break open a such tumbler tip are deformed, so that the Core can no longer be turned.
  • the inventor set himself the task of a rotary lock cylinder to create the type mentioned, in which unauthorized attempts to unlock the vibrating instrument are more effectively difficult.
  • the task is with a generic rotary lock cylinder solved according to the characterizing part of claim 1.
  • the invention is based on the knowledge that with the above Instrument comparatively strong blows on the core pins be exercised. In a rotary lock cylinder according to the invention will inevitably result in these blows, that at least one core pin on his in the key channel protruding end is changed so that a classification the corresponding guard locking by vibration is completely impossible is. If the named end has broken away, then no longer transmit the vibrations to this pin tumbler and thus this tumbler cannot be classified. If the end mentioned is bent or deformed, the corresponding core pin is blocked in its bore and can no longer be moved radially. At a The rotary lock cylinder according to the invention is an unauthorized one Unlocking attempt with a vibrating instrument not only difficult, but completely after a short trial period hopeless.
  • Tumblers 5 and 6 are in on arranged in rows in a known manner and have according to FIG. 2 each has a core pin 12, a housing pin 11 as well as a compression spring 7.
  • the housing pin overlaps 11 the shear line 26 and thus blocks the rotor 3. With an associated flat key it is released for rotation of the rotor 3 the tumbler 5 in the stepped bore 10 moved radially outwards and the pins 11 and 12 arranged.
  • the core pin 12 has a tip 13 a conical ramp surface 15, a body 27 with a radially projecting edge 16 and a connecting pin 14 on.
  • the tip 13 works when the rotary lock cylinder is actuated 1 in a known manner with the control surface a hole in the key together.
  • the tip 13 is made made of a hard material, for example hardened Steel.
  • the connecting pin 14 is in bores 18 and 19 of the body 27 or the tip 13 pressed in and exists made of a material that is softer than that Tip 13.
  • the pin 14 holds the tip 13 in a fixed Distance to body 27. Between tip 13 and the body 27 there is a circumferential groove according to FIG.
  • the connecting pin 14 is dimensioned so that it usual forces when actuating the rotary lock cylinder 1 can be transferred from the tip 13 to the body 27, when striking the tip 13 due to a vibrating However, instruments are permanently bent or broken off becomes. Figures 6 to 8 schematically show this process.
  • FIG. 6 shows an inserted into the key channel 4 Instrument 25, which is designed as a rod-shaped flat tongue and with a vibration device, not shown here connected is.
  • Instrument 25 which is designed as a rod-shaped flat tongue and with a vibration device, not shown here connected is.
  • the top 13 will thereby either torn off or permanently bent.
  • the Figure 7 shows a core pin 12 with a torn Tip 13 and Figure 8 a permanently bent tip 13. Vibrations remain in the situation according to FIG. 7 ineffective on the core pin 12.
  • Figure 8 blocks the curved tip 13 from radial displacement of the core pin 12. In both cases, this has the Consequence that the associated housing pin 11 against the pressure the spring 7 can not be moved.
  • the rotary lock cylinder 1 is thus permanently blocked.
  • FIG. 5 shows a core pin 20 which is an axial one Notch 22 and a circumferential groove 21.
  • the rotary lock cylinder 1 has only one core pin 12, 20 or 23.
  • several or all core pins can also be used according to of the invention.
  • the core pins shown 12, 20 and 23 are only exemplary embodiments, and for it is clear to the person skilled in the art that the invention also applies to another Way could be realized.
