Definitions

  • the invention relates to a lock cylinder - key system, comprising a cylinder housing in which a cylinder core is rotatably mounted, which in turn has an insertable key receiving keyway, wherein in the cylinder core and in the cylinder housing cooperating tumblers are provided, the mechanical coding of the Scan the key and, if the coding is correct, allow the cylinder core to rotate, thus enabling a closing process.
  • the features present on the key such as the profiling of the side surfaces of the key shank and the formation of the notches in the key-chest, determine the mechanical coding of the key.
  • the invention has for its object for a lock cylinder key system to achieve improved copy protection.
  • a lock cylinder - key system with a cylinder housing in which a cylinder core is rotatably mounted, which in turn has an insertable key receiving keyway, wherein in the cylinder core and in the cylinder housing cooperating tumblers are provided, which scan the mechanical coding of the key and, if the coding is correct, allow the cylinder core to rotate, thus enabling a closing process, in that in the key, near the spine, a transverse to the cylinder longitudinal axis arranged magnet is provided, which has a profiling of the key corresponding to the profile that in the cylinder core under the magnetic effect of the key arranged in the magnet parallel to the key channel or to Side surface of the key is provided in a bore of the cylinder core displaceable magnet, which in turn is engageable with a spring-loaded ball - pin combination whose ball engages in a locking shaft groove of the cylinder housing and prevents rotation of the cylinder core, when not in the key channel key while in the key channel located key, by the
  • a stationary magnet is arranged in the side surface of the key.
  • This magnet then attracts a displaceable magnet located in the core, when it has reached the key stop (ie a certain end position).
  • This magnet located in the core blocks a sprung ball - pin combination in which the ball engages the Sperrwellennut of the cylinder housing. It is released when the magnet is pulled from the key magnet to "up”. Then the ball, so ball-pin combination, can dip into the core.
  • the core displaceable magnet is always attracted to the ball-and-pin combination if there is no key in the lock or the key does not carry a magnet in the appropriate position.
  • the ball is in the locked position and blocks a rotation attempt of the cylinder core.
  • the magnet in the cylinder core is - in the illustrated embodiment - arranged displaceably parallel to the keyway or the side surface of the key in a bore of the cylinder core.
  • the blocking of the ball-pin combination takes place - as can be seen - in that this magnet 5 engages in the cylinder core 3 in a recess or undercut in or on the pin 7, so that the ball-pin combination can not move radially in the cylinder core.
  • the magnet 5 is always attracted to the combination if no key 2 is in the lock or the key does not carry a magnet in the appropriate position.
  • the arranged in the key 2 magnet 4 is also used before the profiling of the side surface of the key in the key shank, so that he then receives in the production of the profiling of the side surface a corresponding profiling.

Claims (4)

  1. Système de barillet de serrure/clé, avec un boîtier de barillet (1), dans lequel un noyau de barillet (3) est logé de manière rotative, qui présente de son côté un canal à clé recevant une clé insérable (2), dans lequel des gâchettes coopérantes sont prévues dans le noyau de barillet (3) et dans le boîtier de barillet (1), qui balaient le codage mécanique de la clé (2) et en cas de codage adapté, autorisent une rotation du noyau de barillet (3) et permettant ainsi une opération de fermeture,
    en ce qu'un aimant (4) agencé transversalement à l'axe longitudinal de barillet, qui présente un profilage correspondant au profilage latéral de la clé (2), est prévu dans la clé (2), près du dos de clé,
    que dans le noyau de barillet (3) est prévu un aimant (5) déplaçable sous l'effet magnétique de l'aimant (4) agencé dans la clé (2) parallèlement au canal à clé ou à la surface latérale de la clé (2) dans un perçage du noyau de barillet (3), qui peut être mis en prise de son côté avec une combinaison bille-tige à ressort (6, 7, 8), dont la bille (6), lorsque la clé (2) ne se trouve pas dans le canal à clé, entre en prise avec une rainure d'arbre de blocage (9) du boîtier de barillet (1) et empêche une rotation du noyau de barillet (3), alors que lorsque la clé (2) se trouve dans le canal à clé, l'aimant (5) dans le noyau de barillet (3) est tiré hors de prise avec la combinaison bille-tige (6, 7, 8) par l'aimant (4) se trouvant dans la clé (2) et la bille (6) est pressée contre l'action du ressort (8) hors de la rainure d'arbre de blocage (9) par rotation du noyau de barillet (3).
  2. Système de barillet de serrure/clé selon la revendication 1,
    caractérisé en ce
    que la bille (6) de la combinaison bille-tige (6, 7, 8) est en acier.
  3. Système de barillet de serrure/clé selon l'une quelconque des revendications précédentes,
    caractérisé en ce
    que l'aimant (5) dans le noyau de barillet (3) est réalisé sous forme de barre et est déplaçable dans un perçage prévu parallèlement au plan de canal à clé.
  4. Système de barillet de serrure/clé selon l'une quelconque des revendications précédentes,
    caractérisé en ce
    que l'aimant (5) dans le noyau de barillet peut être mis en prise avec son extrémité tournée vers la combinaison bille-tige (6, 7, 8) avec un évidement ou une contre-dépouille de la tige (7).
