Definitions

  • the invention relates to a lock and key system, comprising a lock cylinder housing with a cylinder core rotatably arranged therein, which has a key channel into which a key provided with profiles on the side of the key shaft as grooves and ribs can be inserted, as well as with core pins that scan the profile and which allow or prevent rotation of the cylinder core, the opening width of at least one of the grooves being checked by the core pins.
  • Such a system is from the US 6134929 A or the US 2012/0073340 A1 known.
  • the key shaft of such flat keys is usually provided with notches on the key face side and has profiles on both sides.
  • the notches and the profile together form a coding that is typical for every key.
  • the invention is therefore based on the object of improving copy protection.
  • a lock-key system comprising a lock cylinder housing with a cylinder core rotatably arranged therein, which has a key channel into which a key provided with profiles on the side of the key shaft as grooves and ribs can be inserted, as well as with core pins which scan the profile and allow or prevent rotation of the cylinder core, the opening width of at least one of the grooves being checked by the core pins .
  • the opening width of the groove tapers from the key tip in the direction of the key chalk in a wedge shape.
  • the lock-key system is preferably designed in such a way that that at least one of the grooves tapers in the opening width from the key tip in the direction of the key head, that the groove can be scanned by core pins, one of which is fixed near the key tip of a key inserted into the keyway, scans the opening width of the groove at this point, that a second core pin is provided which, radially movable, scans the course of the groove in the direction of the key head when the key is inserted into the keyway,
  • the movable core pin is designed to be truncated conical in its area facing the key channel, so that when the key is inserted into the key channel, this core pin with its inclined surfaces, sliding along the longitudinal edges of the groove, is displaced radially with increasing tapering of the groove and - with a matching Key - aligns the cylinder core / lock cylinder housing with an assigned housing pin at the parting line.
  • the lateral profile of the key shaft consists of grooves and ribs running parallel to the back of the key, the depth or height of which can be sensed in a suitable manner, for example by means of housing pins cooperating with core pins. If a correct key is inserted into the keyway, this leads to an alignment of the core and housing pins at the separating plane between the cylinder core and the lock cylinder housing, whereas if the wrong key is used, this separating plane is crossed by one of the pins, so that it enters the respective hole in the other pin protrudes and thus prevents the rotation of the cylinder core.
  • the groove is scanned, preferably with regard to the opening width or width - that is, whether it is present. This can be checked by means of a feeler pin firmly in the cylinder core - pointing in the direction of the keyway. If the dimensions are not correct, this pin prevents further insertion of the key.
  • the key channel in the cylinder core facing the groove on the key shaft only has a narrow profile rib which corresponds to the narrowest point of the groove on the key shaft.
  • the key is denoted by 1 and the lock cylinder has the reference number 2.
  • the lateral profile of the key shaft has at least one groove 4, which tapers in a wedge shape in the direction of the key head, i.e. the longitudinal edges 7 converge.
  • a core pin 5 is provided that is fixedly arranged in the cylinder core, while a movable core pin 6 is located near the head of the key.
  • the cylinder core is denoted by 3, while the reference number 2 denotes the lock cylinder housing in the sectional illustration in the figures.
  • the movable core pin 6 is designed to be truncated conical at its end facing the key or keyway, that is to say has inclined surfaces.
  • the movable core pin rests on the longitudinal edge 7 of the groove 4 and aligns - as usual - with the housing pin 8 at the parting plane 10, so that a locking process could be carried out with this key.
  • the adjustment cannot take place at the parting plane, ie the core pin is pushed back by the housing pin, for example, and this can enter the bore of the core pin via the parting plane.
