Definitions

  • the invention relates to a lock cylinder and reversible key with key withdrawal lock according to the preamble of patent claim 1.
  • An appropriate training is from the JP 2008 169667A known.
  • the function of the key-pull lock is ensured by the mechanism of coding of the individual pins.
  • the pins In key withdrawal position, the pins are movable and are only z. B. held by the spring forces in contact with the key. They also move beyond the dividing plane into the cylinder housing and thus enable the key to be inserted and removed. If the cylinder is rotated in engagement with the appropriate key, the pins move within the cylinder core.
  • the object of the invention is to develop a key withdrawal lock, which allows the removal of a reversible key in lock cylinders only in one or more defined positions.
  • the key pull lock is formed in the illustrated embodiment as a disc 1 and provided with a groove 3.
  • each groove defines a key withdrawal position.
  • the groove-like recess called groove for short, is in the 0/360 ° position.
  • This groove 3 in the disc 1 is associated with at least one corresponding groove 6 in the key shank.

Claims (3)

  1. Cylindre de serrure et clé réversible avec système de blocage d'extraction de clé, dans lequel la clé réversible peut être introduite dans le canal de clé du noyau de cylindre logé de manière à pouvoir tourner dans le boîtier de cylindre de serrure,
    dans lequel
    - un disque (1) annulaire qui est maintenu fixement et sans pouvoir tourner dans le boîtier de cylindre de serrure et qui présente sur la périphérie intérieure au moins une découpe (3) axiale de type rainure, est agencé derrière la tête de noyau de cylindre,
    et la clé sur la tige de clé (2) présente des rainures (6) s'étendant à l'opposé et dans le sens longitudinal axial, dont la dimension correspond à la découpe (3) de type rainure dans le disque (1) annulaire et dont la position dans le sens longitudinal axial sur la tige de clé (2) permet une rotation de la clé introduite complètement dans le canal de clé par rapport au disque (1) annulaire fixe,
    caractérisé en ce
    - que la clé est agencée dans le canal de clé de telle manière que la bande de rotation de son axe de symétrie (5) s'étendant dans la tige de clé (2) s'étende à distance de l'axe de rotation (4) du noyau de cylindre, dans lequel la distance qui mène à une excentricité de la rotation de la clé par rapport à l'axe de rotation (4) du noyau de cylindre, est inférieure à la profondeur de la découpe (3) de type rainure sur le disque (1).
  2. Cylindre de serrure selon la revendication 1,
    caractérisé en ce
    que dans le disque annulaire (1) plusieurs découpes de type rainure (3) sont prévues réparties sur la périphérie intérieure, lesquelles produisent respectivement des positions d'extraction de clé définies.
  3. Cylindre de serrure selon la revendication 1 ou 2,
    caractérisé en ce
    que le disque annulaire (1) se compose de matériau résistant au perçage ou présente des zones partielles correspondantes.
