Definitions

  • the invention relates to a flat key for cylinder locks, which cannot be copied with the previous methods is and refers to conventional systems from Cylinder locks with a profiled vertical key channel.
  • the key is inserted vertically and has corresponding vertical mills.
  • the key profile shaped key channels are of different lengths pins designed in accordance with the milling depth pressed a level and release a dividing line. This ensures that the profile core in the housing can be rotated.
  • Crucial for the functioning this process is the right match between Milling in the key and the length of the corresponding Core pin.
  • the key contains with its symmetrically inserted Milling a so-called code.
  • This milling cutter transfers the corresponding millings congruent on the duplicate key to be produced.
  • all geometrical shapes of the millings are copied based on the Milling process used in the production of the original key were used.
  • Copy milling machines all keys of the aforementioned Systems are copied.
  • DOS 2 632 172 and 2 517 689 are cylinder locks known whose design features reversible key condition, whose wide insertion surfaces are stanchions exhibit. Locking pins engage in these holes of the rotor in the cylinder housing and operate the lock when the key is turned. These keys are by known methods copyable.
  • DE-PS 44 20 015 C 1 is a cylinder flat key known that instead of milled grooves notches has, in which tumbler elements in the form of Pins located in the cylinder core of the lock intervene and set the lock in motion. With that higher copy security can be achieved with it it is necessary that the geometry of the bore with the The geometry of the locking elements must match got to.
  • EP-A-0 599 805 discloses a Cylinder flat key described, the Notches on a narrow side of the key shaft are milled in. To the copy security of the Key using known copy milling machines prevent at least one of these notches milled in such a way that the notch faces the other Broad sides of the key shaft different Have heights.
  • DE 43 16 439 A 1 is a flat key known for locking cylinder, which with locking notches for Classification of tipped pin tumblers, the closing notch flanks being concavely curved surfaces in the form of holes of different depths. To copy this key, there are corresponding drilling devices required.
  • the invention has for its object a flat key for cylinder locks to develop the with the conventional methods using copy milling machines cannot be copied.
  • Figure 1 is the side view of the flat key shown for cylinder locks without handle, in which recesses 1, 2, 3, 4, 5 and 6 axially to the key shank, namely symmetrical milling 1, 2, 4, 5, 6 accordingly the predetermined code are arranged.
  • the flat key also assigns this symmetrical milling 1, 2, 4, 5, 6 instead of one Milling a drilled notch 3, which is arranged so that they are between the asymmetrical profile grooves 7, the lie on both sides of the key shaft.
  • the base of the drilled notch 3 corresponds to the depth the original not machined notch.
  • the profile grooves 7 arise differently high side walls 3a and 3b. Revealed in the lock cylinder itself there are no changes.
  • This principle also allows the attachment of several of these drilled notches 3 instead of symmetrical cutouts.
  • the geometric shape of the drilled notch 3 is so designed a problem-free moving of the tumbler elements is possible with the axial movement of the key.
  • Copying can only be done using a special Copying technology with appropriate tools.
