Definitions

  • the invention relates to a tumbler according to the preamble of independent patent 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.
  • DE-A-1 122866 has disclosed a tumbler of this type.
  • the core pin has a displaceable element made of several rings, which is intended to make it difficult to scan the dividing joint of the tumbler.
  • This tumbler is complex to manufacture and it is still possible to measure and fix the core pin.
  • 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 tumbler according to the invention can be mass-produced in a simple manner. Changes to the other parts of the rotary cylinder lock and the key are not necessary. It is sufficient that, in addition to the usual tumblers, at least one tumbler according to the invention is used in a rotary cylinder lock in order to make it secure against the opening methods mentioned.
  • 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 spitz is made of a hard metal material, wear of the tip through use is 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.
  • 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 In each housing bore 17a there is 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 3 with a connecting part 3a and a head 3b with a control surface.
  • the head 3b can also have a plurality of control surfaces, as a result of which the closing possibilities can be increased in a known manner.
  • the tip 3 is preferably made of a hard metal material or another hard-wearing and abrasion-resistant hard material and is fixed with a firm fit 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 in diameter at the outer end, so that the sliding element 1 can be moved outward with limited stops and has a wider sleeve part 1 a and a narrower sleeve part 1. Inwardly, the sliding element 1 experiences a stop on the sleeve part 1b through the radially outwardly 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 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 from its locking position by the locking pin 24. In the position shown in FIG. 3a, however, the spring 25 has such a great tension that the locking pin 24 follows the housing pin 15 essentially without delay when 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 conventional stepped bores 17b in the cylinder core 13. Due to the step-like configuration of the bore 17b and a corresponding step-like configuration 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 pins 10 and 30 described above have an annular gap 18 between the sliding element 1 and head 3. Seen in the longitudinal direction of the core pin, this is about 0.4 mm wide.
  • a compression spring (not shown) can be arranged in the gaps 18, which presses the sliding element 1 against the shoulder of the pin body 5 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 or 30.
  • the guard locking according to the invention works with authorized key in the same way as a conventional guard locking with authorized key.

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.
