Definitions
- the invention relates to a tumbler according to the preamble of independent claim 1.
- Rotary cylinder locks with two-part tumblers are generally known and have a high security value.
- opening methods have now been developed with which these rotary cylinder locks can be opened without a key and without external damage to the locks.
- the invention is based on the object of creating a rotary cylinder lock of the type mentioned which cannot be opened using these methods.
- the tip of the core pin By manufacturing the tip of the core pin as a separate part and attaching the tip with a tight fit to the pin body, it is possible to manufacture the tip from a material that is particularly resistant to drilling. If the tip is made of a hard metal material, the use of the tip is also largely avoided.
- the formation of the tumbler according to claim 5 also prevents opening methods in which the core and housing pins are separated so that the rotor can be rotated briefly.
- Fig. 2 shows a cross section through part of a
- 3a and 3b a cross section through a rotary cylinder lock with a tumbler according to one
- Fig. 4 shows a longitudinal section through a core pin according to another embodiment.
- the lock cylinder shown in FIG. 2 has, in a known manner, a stationary cylinder housing 12, which is inserted in a cylindrical sleeve 11 and in which a cylinder core 13 is rotatably arranged.
- the cylinder housing 12 and the cylinder core 13 have radial bores 17a and 17b, in which spring-loaded tumblers are slidably mounted.
- a spring 16 which is supported against the sleeve 11 and presses with pretension on a housing pin 15, which in turn presses a core pin 10 radially inward against a key to be inserted into the key channel 14.
- the core pin 10 has a tip
- the tip 3 preferably consists of a hard metal material or another hard-wearing and abrasion-resistant hard material and is fixed in place in a bore 7 in the pin body 5.
- a sleeve-shaped sliding element 1 is slidably mounted on the body 5, a sleeve-shaped sliding element 1 is slidably mounted. Both the sliding element 1 and the body 5 are stepped at the outer end in diameter, so that the sliding element 1 can be displaced outward with limited stops and has a wider sleeve part 1 a and a narrower sleeve part 1 b. Inwardly, the sliding element 1 on the sleeve part 1b experiences a stop through the radially outward projecting head 3b.
- a core pin 30 is shown, which in addition to the sliding element 1 also has a locking pin 24.
- This is mounted in a stepped bore 27 in the pin body 26 to the outside with limited stops.
- a compression spring 25 in the stepped bore 27, which is supported against the tip 3 and presses with pretension on the locking pin 24 which bears against the housing pin 15 at the outer end.
- the tension of the spring 25 is selected so that the housing pin 15 is not moved by the locking pin 24 from its position locking the cylinder.
- the spring 24 has such a great tension that the locking pin 24 follows the housing pin 15 essentially without delay if the two pins are separated from one another.
- the operation of the locking pin 24 is shown schematically in Fig. 3b.
- the housing pin 15 has been briefly moved into an unlocked position by a known opening method, the core pin 30 remaining in its original position.
- the cylinder core 13 can still not be rotated because the locking pin 24 protrudes beyond the shear surface 32 and locks the rotary cylinder.
- the core pins 10 and 30 can be inserted into the usual stepped bores 17b in the cylinder core 13. Due to the step-like design of the bore 17b and a corresponding step-like design of the sliding element 1, the displaceability of the sliding element 1 and of the entire core pin 10 or 30 towards the key channel 14 is limited.
- the core pin can also be designed as shown in FIG. 4.
- the body is made from one piece and has a cylindrical shaft 41 and a head 40 with an approximately hemispherical control surface.
- a cylindrical sliding element 42 is displaceably mounted on the shaft 41, the sliding element 42 being somewhat shorter than the shaft 41.
- the sleeve-shaped sliding element 42 When displaced in the axial direction, the sleeve-shaped sliding element 42 experiences a stop on the head 40 on the inside and a stop on the outside Housing pin 15, not shown here, which is designed as described.
- the .43 core pin is particularly inexpensive to manufacture and is particularly suitable for a rotary cylinder lock with a wrench.
- the core pins 10, 30 and 43 described above have an annular gap 18 and 48 between the sliding element 1 and 42 and the head 3 and 43, respectively. Seen in the longitudinal direction of the core pin, these are about 0.4 mm wide.
- a compression spring (not shown) can be arranged, which presses the sliding element 1 against the shoulder of the pin body 5 or the sliding element 42 against the housing pin 15.
- the tension of this compression spring is comparatively small, but ensures that the gap 18 is retained when the core pin 10, 30 or 43 is pushed outwards.
- this compression spring has the further advantage that here the sliding element 42 also takes over the mode of operation of the locking pin 24. The sliding element 42 and the compression spring thus effectively prevent the lock from being opened by separating the core and housing pins and, at the same time, also prevent the effective part of the core pin from remaining movable during attempts to press on and out.
- the guard locking device works in the same way as a conventional locking device with the key provided.

Abstract
L'arrêt (10, 15), soumis à la charge d'un ressort, présente une goupille de boîtier (15) et une goupille centrale (10). Cette dernière goupille a une course limitée vers le canal de la clé (14), étant disposée dans un perçage à gradins (17b) du noyau cylindrique (13). Sur la goupille centrale (10) est disposée une douille coulissante (1), ayant une forme correspondante à celle dudit perçage a gradins (17b). L'arrêt d'après l'invention (10) peut être inséré dans les serrures cylindriques courantes et empêche de manière efficace une ouverture non autorisé, ouverture essayée sans clé et sans détériorer les serrures.The stop (10, 15), subjected to the load of a spring, has a housing pin (15) and a central pin (10). The latter pin has a limited stroke towards the key channel (14), being arranged in a stepped bore (17b) of the cylindrical core (13). On the central pin (10) is disposed a sliding sleeve (1), having a shape corresponding to that of said stepped bore (17b). The stop according to the invention (10) can be inserted into standard cylindrical locks and effectively prevents unauthorized opening, attempted opening without a key and without damaging the locks.
