Definitions

  • Such a lock cylinder is in the DE 10 2011 015 314 A1 disclosed.
  • a disc cylinder is also from the EP 0 712 979 B1 known.
  • a lock cylinder 10 may have a cylinder housing 12 and a cylinder core rotatably mounted about a cylinder axis in the cylinder housing 12, which is also referred to below as a window housing 14.
  • the rotational movement of the cylinder core or the disk housing 14 can be transmitted via a coupling portion 30 connected to the disk housing 14 on a locking mechanism of a lock, not shown, and the lock thus unlocked or locked by means of the lock cylinder 10.
  • a plurality of rotatable shims 16 which are also referred to as tumblers, taken along the cylinder axis in succession.
  • the shims 16 have respective central receiving openings 18, which together form a keyway 28 for insertion of a key 24 and which in the example shown have a rectangular cross-section.
  • the shims 16 further have respective peripheral recesses in the form of locking recesses 20 for receiving a locking pin 22 which is aligned parallel to the cylinder axis.
  • the locking pin 22 is received radially movable in a provided in the wall of the disc housing 14 slot 32.
  • the locking pin 22 assumes a radially outer blocking position. In this blocking position, a portion of the locking pin 22 engages in a provided on the inner wall of the cylinder housing 12 locking pin receiving recess 34 so that the disc housing 14 (apart from a slight torsional backlash) is blocked against rotation relative to the cylinder housing 12.
  • the shims 16 can be transferred from its locking position into an unlocked position.
  • the locking recesses 20 of all shims 16 in the direction of the cylinder axis are aligned with each other and radially aligned with the locking pin 22.
  • the locking pin 22 can then be displaced radially inwardly into its release position, in which it is located outside the locking pin receiving recess 34. This will the disc housing 14 is released for rotational movement relative to the cylinder housing 12 and the disc housing 14 can be further rotated together with the shims 16 in the unlocking until reaching the unlocked position.
  • a fixing recess 44 for receiving a core pin 46 is further provided on the outer periphery of each dial 16.
  • the core pin 46 is aligned parallel to the cylinder axis and received radially movable in a slot provided in the wall of the disk housing 14. In the closed position of the lock cylinder 10, the core pin 46 engages in the FixierausEnglishept 44 of the shims 16 and thus prevents rotation of the shims 16 to each other when no key 24 is inserted.
  • the lock cylinder 10 associated key 24 has a plurality of different angled incisions 26, the different angular positions of the locking recesses 20 of the shims 16 correspond.
  • the key 24 After insertion into the keyway 28, the key 24 initially receives a so-called initial position, from which the key 24 can be rotated in the unlatching direction.
  • the key 24 By turning the key 24 in the unlocking from the initial position out of the key 24 first enters a so-called zero position in which the core pin 46 can get out of engagement with the FixierausEnglishept 44 of the shims 16 and the shims 16 thus for a rotational movement relative to the disc housing 14th are released in order to bring the locking recesses 20 of the shims 16 in succession in alignment (so-called sorting).
  • the shims 16 have relative to the respectively associated recess 26 of the key 24 a certain backlash whose dimension depends on the angular extent of the respective incision 26, ie depending on the angular size of the incisions 26 reach control sections of the respective incisions 26 and corresponding control portions of the central receiving openings 18 of the associated respective shims 16 when sorting at different times or in different angular positions with each other.
  • the exemplary lock cylinder 10 corresponds to a coding "1" rotation of the dial 16 by about 20 °, an adjacent coding "2" a rotation of about 38 °, etc., and finally a coding "6" of a rotation of about 110 °, in each case measured from the zero position until reaching the sorting end position.
  • the locking recesses 20 are accordingly arranged in an angular distance corresponding to the respective coding of the locking pin receiving recess 34 of the cylinder housing 12 when the shims 16 are in the zero position.
  • a positive coupling between the corresponding shim 16 and the associated portion of the key 24 may be provided, ie there is no incision or a cut with the angle 0 °, so that no backlash between the key 24 and the Shim 16 is.
  • a dial 16 of the code "1" is thus basically only at the end of the rotary operation of the key 24, i. after a rotation of about 90 °, taken and brought by a rotation of the key 24 by a further approximately 20 ° in their final sorting position.
  • a disc cylinder can also have one or more so-called lifting discs, which are usually shims.
  • Each lifting disc has the coding "6" and is arranged in a predetermined axial position in the disc housing, e.g. with respect to the Jardineinfuelides the very front, the very back or in the middle of the lock cylinder 10.

  • shims 16 which are rotatably coupled to the disc housing 14 or coupled with torsional backlash.
  • the intermediate discs 36 decouple adjacent shims 16 from each other, so that the rotational movement of a respective shim 16 does not cause friction by a co-rotation of the adjoining shim 16 thereto.
  • Such a takeaway could in fact lead to circumstances a dial 16 is rotated beyond its unlocked position and thus the lock cylinder 10 can not be opened.
  • the rotationally fixed coupling of the intermediate disks 36 with the disk housing 14 can be effected by stop sections 40 of the intermediate disks 36 extending at least partially in the radial direction ( Fig. 26 ), which abut against corresponding, formed on the inner wall of the disc housing 14 projections 42.
  • each washer 36 has a peripheral recess 38 which is radially aligned with the locking pin 22.

The same applies preferably to the circumferential recess 38a with respect to the core pin 46th
  • Lock cylinder of the type described above have proven to be advantageous tamper resistant. Nevertheless, an unauthorized person with the aid of a suitable, so-called picking tool try to scan the individual shims one after the other and thereby sort one after the other, ie to bring into the respective sorting position, then unlock the lock cylinder.
