Definitions

  • the invention relates to a lock-key combination with a profile of the side surfaces of the key.
  • the key back is used as the reference edge for an accurate production of the notch depths.
  • the invention has for its object to complicate the replacement of key copies.
  • This object is achieved according to the invention in that the continuous profiling runs at an angle different from 0 ° to the key back, so that when the key is inserted into the lock, it is guided in a direction deviating from its longitudinal axis.
  • the profiling according to the invention is therefore not, as is generally customary, parallel to the key spine, but at an angle which is preferably between 5 and 10 ° .
  • This configuration of the profiling significantly increases the uncontrolled replacement of key duplicates, in particular in the case of one-off production when the blank is not present, due to the degree of freedom of the angular arrangement that must also be taken into account.
  • FIG. 1 the cylinder housing is indicated by 13 and the cylinder core by 14.
  • the key 15 has a profile 1, which extends at an angle a to the key back 16.
  • the key 15 is inserted into the key channel of the cylinder core 14, but it carries out a movement obliquely upwards. Depending on the angle, this movement will hardly be noticed by the actuator.
  • the profiling and the key notches interact with the usual scanning devices, only the tumblers 17 being indicated in FIG. 1.
  • the back of the key 16 is disengaged in a suitable manner in regions and interacts with fields or projections 6-8 on the cylinder core 14.
  • These fields or projections 6 to 8 act as a kind of stops, which are passed under when the key is inserted into the key channel. Only a key whose back is matched to the arrangement of these fields or protrusions can be fully inserted into the key channel.
  • countersinks can be provided in the cylinder core. A part of this is filled in according to the coding of the fields or protrusions 6-8, while the rest remain free, so that when the cylinder core is rotated, pins, e.g. Housing pins that can sink into. In this way, further rotation can be prevented.
  • pins e.g. Housing pins that can sink into.
  • the profiling 2 can also run in an arc shape - that is, with a changing angle.
