Definitions

  • the invention relates to a locking system according to the preamble of independent claim 1 and a key for such a locking system.
  • Locking systems of the type mentioned are generally known. These usually have many hierarchically arranged flat keys with which a correspondingly large number of locking cylinders can be operated.
  • the keys are flat keys, as are known, for example, from DE-C-3 021 334 by the applicant. From this document it is also known that the number of closings can be significantly increased by drilling with several control surfaces and corresponding tumblers. The number of locking variants can be increased by other measures, for example by shifting the lines of the prototype.
  • the invention has for its object to provide a further way to increase the number of locks of a locking system of the type mentioned. This should be possible in a structurally simple manner and without impairing the functional reliability.
  • the object is achieved by the invention according to claim 1.
  • the security keys are so-called non-reversible keys and, for example, can be recognized as such immediately by the shape of the key head.
  • the key In order to open a lock, the key must be inserted into the key channel in one of the two possible rotary positions.
  • some of the locking cylinders have rotors that are rotated by 180 ° with respect to the cylinder housing about their longitudinal axis compared to the other rotors.
  • the rotors can have open or closed key channels.
  • An essential advantage of the locking system according to the invention is that two completely independent locking codes can be arranged on one key. By reducing the rotational symmetry of the keys and the associated tumblers, the number of locking variations is practically doubled. This is well compatible with other known measures to increase the closing variations.
  • the bores can also be stepped bores and a line displacement of the bore patterns is also possible at the same time.
  • the measures required on the locking cylinders are comparatively simple and do not change the basic structure of the locking cylinders.
  • the number of tumblers in the locking cylinders does not have to be increased compared to comparable cylinders. Cost-effective key production is also guaranteed.
  • a higher-level key is equipped with two independent locking codes, while a lower-level key only receives one code.
  • a key of the system according to the invention preferably has at least two different rows of bores, which are arranged opposite one another on the wide side surfaces of the key shaft. With the key, two different locking cylinders with the same or different locking code can thus be opened without having to be turned.
  • 1a to 1c show a flat key with a shaft 2 and a key head 3.
  • the shaft 2 has six different drilling rows A to F, each with five holes, for example. These bores are simple counterbores or stepped bores, which work together with assigned tumblers in the locking cylinders.
  • the key has two independent locking codes, which are formed by the drill rows A, E and D or by the drill rows B, C and F.
  • Each group of drill rows consists of a drill row E or F with upright bores on the narrow sides 13 or 14 and lateral bores on the wide side surfaces 15 or 16. As can be seen, the bores cannot be made to coincide by turning the key about its longitudinal direction as would be the case with a reversible key.
  • the key head 3 for example, has an asymmetrically arranged opening 4.
  • the key 1 can be L-shaped.
  • lock cylinders 5 and 6 of a system according to the invention are shown schematically.
  • These lock cylinders can be simple lock cylinders or double lock cylinders, but also other special cylinders. Different cylinder profiles are also possible.
  • a rotor 9 is inserted into the cylinder housing 11 in the usual orientation. Core pins a, e and d project into a key channel 7 in the usual way. This cylinder can completely correspond to a known cylinder.
  • a rotor 10 is inserted into a cylinder housing 12 and is rotated by 180 ° about its longitudinal axis with respect to the rotor 9. The closing channel 8 of the rotor is thus open at the top.
  • Core pins b, c and f protrude into the key channel 8, which are also designed as usual.
  • the tumblers are arranged with the core pins a, d and e so that the rotor 9 can be turned and the corresponding lock can be opened. If the key 1 is inserted into the key channel 8 of the locking cylinder 6 in the same orientation, the core pins b, c and f are now arranged through the drill rows B, C and F, so that this rotor 10 can also be rotated.
  • a lock with the locking cylinder 6 can be opened with these subordinate keys, but not a lock with the locking cylinder 5.
  • all inner doors are now equipped with locking cylinders 5 and all outer doors with locking cylinders 6.
  • the number of locking options can in particular be significantly increased by providing the locking cylinders 5 and 6 with different permutations.

Abstract

Dispositif de fermeture présentant des cylindres de fermeture (5) dans lesquels la partie rotative (9) est située de la façon habituelle dans le bâti du cylindre (11), et comportant de plus, des cylindres de fermeture (6) dans lesquels la partie rotative (10) est tournée à 180° autour de son axe longitudinal par rapport aux autres parties rotatives (9) susnommées. Les clés de sécurité correspondantes sont des clés plates et des clés non tournantes possédant, lorsqu'il s'agit de clés principales, deux codes de fermeture totalement indépendants l'un de l'autre. L'invention met en valeur une possibilité supplémentaire d'augmenter les variations de fermeture et, de ce fait, la sécurité de fermeture.

Claims (7)

  1. Installation de fermeture avec au moins une clef (1) et deux cylindres de fermeture (5, 6) présentant, chacun, au moins un rotor (9, 10) à plusieurs séries de gâchettes (a à f) et une fente à clef (7, 8) pour l'introduction de la clef de sécurité plate présentant plusieurs séries d'alésages (A à F), caractérisée en ce que le rotor (9, 10) de l'un des cylindres de fermeture (5, 6) est, par rapport au rotor (10, 9) de l'autre cylindre de fermeture (6, 5), tourné sur son axe longitudinal de 180° par rapport au boîtier de cylindre (11, 12) et que la clef (1) est une clef sans inversion et qu'elle est pourvue d'alésages (A, F) pour l'engagement des unes des séries de gâchettes (a, e, d) de l'un des cylindres (5, 6) et/ou des autres séries de gâchettes (b, c, f) de l'autre cylindre de fermeture (6, 5).
  2. Installation de fermeture suivant la revendication 1, caractérisée en ce que les deux rotors (9, 10) présentent des codes de base ou des codes de fermeture différents.
  3. Installation de fermeture suivant la revendication 1 ou 2, caractérisée en ce qu'une clef sans inversion (1) est une clef principale et que des clefs à inversion sont également prévues pour le cylindre de fermeture, en tant que clefs auxiliaires.
  4. Clef pour une installation de fermeture suivant la revendication 3, caractérisée en ce qu'elle est reconnaissable comme clef sans inversion grâce au façonnage asymétrique de la tête de clef (3).
  5. Clef suivant la revendication 4, caractérisée en ce qu'elle présente un ou deux groupes de séries d'alésages (A, D, E; B, C, F) qui représentent, chacun, un code de clef et qui sont disposés sur un côté étroit (13, 14) du panneton de clef (2) (Figure 1c).
  6. Clef suivant la revendication 5, caractérisée en ce qu'au moins un groupe comporte trois séries d'alésages (A, E, D, respectivement B, C, F), une série d'alésages (E, respectivement F) étant constituée par des alésages à bords relevés et les deux autres séries d'alésages (A, D, respectivement B, C) par des alésages latéraux opposés sur les faces latérales larges (15, 16) du panneton de clef (2).
