Definitions
- the invention relates to a rotary lock cylinder for a security lock, with a cylinder housing and a rotor rotatably mounted therein and with a plurality of pin tumblers which are to be assigned with a key to be inserted into a key channel of the rotor in order to release the rotor.
- Rotary lock cylinders of this type have been known for a long time and have proven themselves in practice.
- Various measures are known to the person skilled in the art in order to increase the security against unlocking of such rotary lock cylinders. These are directed in particular against unauthorized unlocking attempts in which the pin tumblers are arranged by vibration with an instrument inserted into the key channel.
- the known measures against such attempts have the effect that the time required for arranging the pin tumblers is considerably increased. The consequence of this is that such unauthorized attempts are generally terminated.
- the inventor has set himself the task of creating a rotary lock cylinder of the type mentioned, in which unauthorized unlocking attempts with the instrument mentioned are more effectively made more difficult.
- the object is achieved in a generic rotary locking cylinder in that at least one pin tumbler has a core pin, the front and in the Key channel protruding end is designed such that it is bent, deformed, or broken away in the event of an unauthorized attempt to unlock using a vibrating instrument.
- the invention is based on the knowledge that comparatively strong blows are exerted on the core pins with the instrument mentioned. In the case of a rotary lock cylinder according to the invention, these impacts inevitably result in at least one core pin at its end projecting into the key channel being changed in such a way that it is completely impossible to arrange the corresponding tumbler by vibration. If the end mentioned has broken away, the vibrations are no longer transmitted to this pin tumbler and thus this tumbler cannot be classified.
- the core pin has a circumferential groove immediately behind a conical run-up surface, and this groove is visible in the key channel in the rest position of the core pin. It has been shown that in a test mentioned the vibrating instrument often engages in this circumferential groove and the front end of the core pin is broken away. This core pin then no longer or only slightly protrudes into the key channel and can no longer be displaced radially by vibration. Of course, the circumferential groove must be so deep that the front end is bent, deformed or broken away in the event of vibration. It has been shown that the functionality of the core pin is not impaired in the case of a comparatively deep groove. The invention can be achieved, for example, by a simple radial incision at the front end of a Core pin can be realized very inexpensively. The invention thus not only enables the unlocking attempts mentioned to be completely prevented, but also a very cost-effective implementation.
- FIG. 1 shows a view of a rotary lock cylinder according to the invention
- FIG. 2 shows a cross section through part of the rotary lock cylinder according to the invention according to FIG. 1,
- FIGS. 3 to 5 partially cut core pins
- FIG. 6 shows schematically the mode of operation of the vibration method using a partial cross section through the rotary lock cylinder according to the invention
- FIGS. 7 and 8 partial cross sections through a rotary lock cylinder according to the invention after an unauthorized unlocking attempt.
- FIG. 1 shows a rotary lock cylinder 1 with a cylinder housing 2, also called a stator, a rotor 3 rotatably mounted in the housing 2 with a key channel 4 and tumblers 5 and 6.
- the tumblers 5 and 6 are arranged in rows in a manner known per se According to FIG. 2, a core pin 12, a housing pin 11 and a compression spring 7 each.
- two slides 8 are inserted into the housing.
- the housing pin 11 overlaps the shear line 26 and thus blocks the rotor 3.
- the tumbler 5 in the stepped bore 10 is displaced radially outwards to release the rotor 3 and the pins 11 and 12 are inserted ⁇ ordered.
- the core pin 12 has a tip 13 with a conical running surface 15, a body 27 with a radially projecting edge 16 and a connecting pin 14.
- the tip 13 cooperates in a known manner with the control surface of a bore in the key.
- the tip 13 consists of a hard material, for example hardened steel.
- the connecting pin 14 is pressed into bores 18 and 19 of the body 27 or the tip 13 and consists of a material which is softer than that of the tip 13.
- the pin 14 holds the tip 13 at a fixed distance from the body 27. Between the According to FIG. 3, the tip 13 and the body 27 have a circumferential groove.
- the connecting pin 14 is dimensioned such that it can transmit the usual forces from the tip 13 to the body 27 when the rotary lock cylinder 1 is actuated, but is permanently bent or broken off when the tip 13 is struck due to a vibrating instrument.
- FIGS. 6 to 8 schematically show this process.
- FIG. 6 shows an instrument 25 inserted into the key channel 4, which is designed as a rod-shaped flat tongue and is connected to a vibration device (not shown here). If such an instrument 25 gets caught in a groove 17 of a core pin 12 as shown, comparatively strong impacts are exerted by the vibration of the instrument 25 on the tip 13. The top 13 will thereby either torn off or permanently bent.
- FIG. 7 shows a core pin 12 with a torn off tip 13 and FIG. 8 shows a permanently bent tip 13. In the situation according to FIG. 7, vibrations on the core pin 12 have no effect. 8, the curved tip 13 blocks a radial displacement of the core pin 12. In both cases, this means that the associated housing pin 11 cannot be moved against the pressure of the spring 7. The rotary lock cylinder 1 is thus permanently blocked.
- a radial slot 24 is worked into a core pin 23 immediately behind the run-up surface 15.
- FIG. 5 shows a core pin 20 which has an axial incision 22 and a circumferential groove 21.
- the rotary locking cylinder 1 has only one core pin 12, 20 or 23.
- several or all core pins can also be designed according to the invention.
- the core pins 12, 20 and 23 shown are merely exemplary embodiments, and it is clear to the person skilled in the art that the invention could also be implemented in another way.
