Definitions

  • the invention relates to a key profile for flat key, which is formed on the side surfaces of the key shank and cooperates with a corresponding profiling in the keyway of a cylinder housing rotatably mounted in the lock cylinder housing.
  • the object of the invention is to provide a key profile which offers improved copy protection and also greater resistance to so-called electro-picking.
  • a key profile for flat keys which is formed on the side surfaces of the key shank and cooperates with a corresponding profiling in the keyway of a cylinder core rotatably mounted in the lock cylinder housing, thereby, that the profiling of the keyway has profile features whose profile base extends in a wedge shape in the direction of the key back receiving recess in the keyway and the upper, the recess facing surface substantially horizontally - based on the key longitudinal plane - and wherein the respective opposing profile features with her tapered area on the same horizontal plane and at the same angle to each other and to the key longitudinal plane.
  • the pick finger performs a very fast vertical movement in the keyway.
  • the pick-finger is guided upwards by the wedge surface away from the core pin and blocked in the downward movement by the horizontal surface, so that the probability that the pick-finger intercepted or even breaks off.
  • the wedge-shaped profiling of the key back has been selected as the reference for indicating the direction. Since the profile of the key channel corresponds to that of the key, the direction specification is therefore understandable and unambiguous even for this key.
  • a wedge-shaped profiling of at least 25 ° has proved to be advantageous because slightly false values are found in the copy attempt by means of scanning.
  • the profile bases of the profile features can vary in their distance from the key longitudinal plane.
  • At least some of the profile features are paracentric.
  • the profile features can have catch grooves.
  • the figure shows a schematic cross section through a lock cylinder core with the keyway.
  • the lock cylinder core is designated 1 in the illustration.
  • the upper profile areas, to which the reference numerals 4 and 5 indicate, are opposite to the starting points 6 and 7.
  • the cross lines 8 are shown.
  • the inclination angle 3 is the same for all profile features - in the illustrated embodiment and is at least 25 °.
  • a core pin 2 is shown, this is to serve to show in which direction an inserted electric pick would work and why he would break off in this profile configuration.
  • at least some of the profile features are paracentric, which increases the likelihood of a picking tool becoming stuck.
  • catch grooves 9 which are located in the key back receiving recess in the keyway facing, substantially horizontal upper surface of the cylinder core side profile feature.

Claims (5)

  1. Profil de clé pour clé plate qui est réalisé au niveau des surfaces latérales de la tige de clé et coopère avec un profilage correspondant dans le canal de clé d'un coeur de cylindre (1) placé de façon à pouvoir tourner dans le logement de cylindre de serrure,
    dans lequel le profilage du canal de clé présente des caractéristiques de profil dont le fond de profil (4, 5) évolue de façon cunéiforme en direction de l'évidement recevant le dos de clé dans le canal de clé et dont la surface supérieure tournée vers l'évidement évolue de façon sensiblement horizontale sur le plan de clé longitudinal,
    caractérisé en ce que les caractéristiques de profil opposées respectivement se terminent avec leur zone réduite sur le même plan horizontal (6, 7) et évoluent sous le même angle les unes par rapport aux autres et par rapport au plan de clé longitudinal.
  2. Profil de clé selon la revendication 1,
    caractérisé en ce que
    le profilage cunéiforme, l'angle d'inclinaison, est d'au moins 25° par rapport au plan de clé longitudinal.
  3. Profil de clé selon l'une quelconque des revendications précédentes,
    caractérisé en ce que
    les fonds de profil des caractéristiques de profil varient dans leur distance par rapport au plan de clé longitudinal.
  4. Profil de clé selon l'une quelconque des revendications précédentes,
    caractérisé en ce que
    quelques-unes des caractéristiques de profil sont réalisées de façon paracentrique.
  5. Profil de clé selon l'une quelconque des revendications précédentes,
    caractérisé en ce que
