Definitions

  • the invention relates to a lock and key system, especially for locking systems, and has set itself the task of being able to offer greater security against unlocking locks.
  • the invention inversely proposes that the known assign the invariant basic profile to the area of the key face bearing the classification notches and to provide this with at least two profile designs (paracentric profile design) that cross the key center line and the variation or system profile in the key spine adjoining section
  • the variation or system profile should have at least one over.
  • the key side surfaces have protruding locking rib profile and the profile incisions of the invariant basic profile and the variation or system profile a rectangular cross section.
  • FIG. 1 shows the prior art, from which the invention forms a departure.
  • This state of the art represents 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 is assigned 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.
  • FIG. 2 shows a superordinate key largely undressed from the variation profile
  • FIGS. 3 and 4 show keys with indicated variation profile configurations. Both keys, however, 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 pracentricity which exceeds the center line 9 at three points.
  • the indicated key channel 10 in this section has a jagged course that largely prevents the use of probing tools.
  • the other profile incisions 12 also have a rectangular cross section. After all, it is for security against the unauthorized opener. of the lock it is important that the key has at least one locking rib profile, ie a profile which projects beyond the key compartment side, so that reworking of the key could only be carried out by applying material. In the embodiments in Figures 2 to 4, 4 locking ribs are provided.
