Definitions

  • the invention relates to a cylinder lock flat key combination for the formation of locking systems with a superordinate general key and subordinate keys, where all the locks of the given system can be operated with the superordinate general key and only a certain group of subordinate locks can be operated with the subordinate keys.
  • Locking systems with a superordinate general key and with at least one subordinate flat key are known, in which with the superordinate general key the master cylinder lock and all subordinate locks of the system, with the first subordinate key the first subordinate cylinder lock and the second to nth subordinate cylinder lock bis finally the nth subordinate cylinder lock can be operated with the nth subordinate cylinder lock.
  • the rotation of the cylinder core is caused by the alignment of the end faces of the spring-loaded radial tumblers so that they are flush with the circumferential surface of the cylinder core, which is achieved with the help of teeth or incisions on the lower narrow edge of the inserted corresponding key.
  • each subsequent subordinate key projects at least partially or in part over the profile of the superordinate key and the corresponding profile of the assigned key channel.
  • the subordinate key cannot therefore be inserted into the key channel of the superordinate key, while the superordinate key can be inserted into the key channel of the superordinate cylinder lock and into the key channels of all subordinate cylinder lock stages.
  • a disadvantage of these locking systems is that both for each group of cylinder locks, i.e. for the main, the first subordinate to the nth subordinate group, you have to develop a different profile of the key and the key channel, which is particularly important in the manufacture of the Key channels is expensive, as well as in the Possibility of easy creation of the higher-level key from the lower-level key by simply grinding off the outstanding profile part.
  • Locking systems consisting of cylinder locks and flat keys are also known, in which the profiles of the superordinate key and the subordinate keys and therefore also their key channel profiles are identical, but the radial tumblers are made from several parts, so that the tooth depth or depth of the incisions of the superordinate key is different from the tooth depth of the subordinate keys.
  • the subordinate keys can therefore be inserted into the key channels of the superordinate locks, but due to the non-unlocking of all radial pin tumblers caused by the different tooth depth of the subordinate keys, the cylinder core cannot be rotated.
  • Locking systems with the combination of the two locking systems listed above are also known, in which the subordinate keys of the individual groups of the locking system have both different key and key channel profiles and a different depth of the incisions in the lower flat key narrow side. These locking systems eliminate the disadvantage of the small number of possible combinations of the locking systems described above with identical profiles of the superordinate key and the subordinate key.
  • a locking system which consists of a cylinder lock and a flat key which, in addition to the incisions in the lower key narrow side, which work with spring-loaded radial tumblers and in addition to the profile grooves and ribs on the key broad sides, contains an additional variation groove ,
  • This additional variation groove is formed in a broad side of the flat key near its guide back. It starts with one Start-up extension at the key tip and runs curved or in the form of a wavy line along the upper guide back of the key, so that the distances from the guide back have at least two locations on the lower edge of the additional variation groove have a different value.
  • the additional variation groove is used to unlock the additional unsprung side locks that are guided in the guide shafts of the cylinder core, the longitudinal axes of which run vertically and parallel to the key channel level.
  • the side tumblers the lengths of which correspond to the lengths of the guide shafts or the length of the circumferential circular chord of the cylinder core, are included
  • side tumblers serve as additional security elements of the locking system with spring-loaded radial pin tumblers controlled by the incisions on the lower key narrow side, and cannot serve to differentiate the higher-level and lower-level cylinder lock in locking systems with a higher-level general key and lower-level keys.
  • the length of at least one arm of the side tumbler of the superordinate cylinder lock which cooperates with the mentioned function point with its side projection, being at least one dimension jump larger, than the length of the corresponding arm of the side lock of the subordinate cylinder lock, the arm of the side projection being shortened when the sub cylinder lock is locked by the arms, in the direction of the vertical dimension jump of the functional point of the variation groove of the subordinate Key is carried out by the functional unit of the variation groove of the parent key.
  • the length of the side lock of the higher-level cylinder lock is at least one dimension larger than the length of the side lock of the lower-level cylinder lock.
  • variation grooves are formed on the two broad sides of the flat key.
