Definitions

  • the invention relates to a lock and key system, in particular for locking systems, in which the keys are equipped with an invariant basic profile in the area of the key face bearing the classification notches, as well as with at least two profile designs that exceed the key center line, and have a system or variation profile in the section adjacent to the key spine .
  • DE-A1 28 17 966 also describes invariant basic profiles with at least two profile configurations that cross the key center line.
  • the invention is based on the object of further increasing the security against scanning in a lock key system.
  • the object is achieved according to the invention in that the system profile or variation profile has at least one locking rib profile projecting beyond the bowl side surfaces and in that the profile incisions of the invariant basic profile and the system profile or variation profile have a rectangular cross section with a width of 0.6 mm, these being provided by milling disks have been generated.
  • milling disks are used to produce the rectangular cross-sections of 0.6 mm width, not only can a large number of these profile cuts be accommodated in the smallest space, but also the security against probing attempts is significantly improved because - due to the shape and arrangement - the Accessibility is difficult.
  • FIGS. 2 to 4 represent exemplary embodiments.
  • Fig. 1 shows the prior art, from which the invention forms a departure.
  • This state of the art is a key 1, in which the basic profile 2 is assigned to the section adjacent to the key back 3 and the variation profile 4 to the section adjacent to the key face 5 provided with classification incisions.
  • Possible profile variations are indicated in FIG. 1, and it goes without saying that the key channel in the region of the variation profile must have at least the opening indicated by dashed lines at 6 and, in the basic form, a straight-line opening.
  • FIGS. 2 to 4 The invention shown in FIGS. 2 to 4 is characterized in that the invariant basic profile 7 is moved into the key section 5 containing the classification notches, while the system or variation profile 8 belongs to the section near the key back, which can extend to the key center part.
  • 2 shows a superordinate key largely undressed from the variation profile
  • FIGS. 3 and 4 show keys with indicated variation profile configurations.
  • Both keys have in common that in the lower section, namely that of the key chest 5, they carry a basic profile 7 which, as the exemplary embodiments show, consists of a paracentric which crosses the center line 9 at three locations.
  • the key channel 10, indicated by dashed lines, has a jagged course in this section, which largely prevents working with probing tools.
  • the other profile incisions 12 also have a rectangular cross section.
  • the key has at least one locking rib profile, i.e. a profile that protrudes beyond the flat side of the key, so that the key could only be reworked by applying material.
  • 4 locking ribs are provided.
  • the rectangular cross-section of the profile cuts or elevations also enables economical production of the keys by means of the milling discs in comparison to the milling heads usually required, because milling discs can be put together in any number of sets and thus for any number of keys, whereas milling heads of conventional design only can be used to produce a specific key.
