Definitions

  • the present invention relates to a key and rotary lock cylinder according to the preamble of independent claim 1 and a key for a rotary lock cylinder and a rotary lock cylinder for a key.
  • Rotary lock cylinders and matching keys have become known from the prior art. It can be classified radially with the key tumblers, so that the rotor can be pivoted to the stator of the rotary lock cylinder when the tumblers coincide with the holes.
  • the disadvantage of the prior art is that the number of locking combinations or permutations depends essentially on the design of the tumblers between the rotor and stator and the corresponding holes in the key. Furthermore, the profiled keys can be very easily copied.
  • the invention has for its object to provide a key and rotary cylinder of the type mentioned, wherein the number of Schliesskombinationen or Schliesspermutation is increased.
  • the object is solved by the invention according to claim 1.
  • the inventive rotary lock cylinder comprises a rotor, a stator and a plurality of tumblers. Furthermore, the key comprises control elements, such as bores or stepped bores, for actuating or classifying the tumblers.
  • the rotary lock cylinder further comprises at least one coding element and the key comprises at least one coding track which is suitable for the coding element and extends in the plugging direction. Coding element and coding path work together.
  • the security against manipulation is increased because two different elements, namely the usual tumblers and further the coding element with the coding track, must be consistent to operate the lock.
  • the key can only be fully inserted into the rotor if the coding element and coding path match.
  • the key can be inserted into a keyway extending along the rotor axis, the coding element preferably protruding into the keyway.
  • the keyway is located in the rotor.
  • the coding element with respect to the key channel is held stationary in the rotor. Under stationary is understood that the coding element is fixed to the key channel and is not movable to this.
  • the coding element is preferably pressed into a bore running perpendicular to the rotor axis in the rotor.
  • the coding element must project in the correct position to the key channel in the key channel.
  • the orientation of the coding element to the key channel plays no role, wherein the coding element is then installed in the wrong position.
  • both the asymmetrical and the symmetrically formed coding element are fixed or fixed to the key channel.
  • the coding portion of the coding element has at least one coding recess, wherein particularly preferably at least two coding grooves are present, which have the same or a different cross section when viewed in the plugging direction.
  • the coding path is arranged symmetrically with respect to a plane passing through a central axis in the key shank or through the rotor axis on the key shank.
  • the key can thus be used as a reversible key.
  • the coding path is arranged in a groove extending in the key shank.
  • the groove comprises two opposite side walls provided by the key shank which extend in the direction of the rotor axis, both side walls to the interior of the groove being provided with said coding track.
  • the coding path is provided in a shaft member communicating with the key shaft.
  • the shaft member may be provided, for example, as a key cap, which is connected to the key tip.
  • the key cap has the advantage that it is reusable.
  • the coding path is arranged in the key tip and only partially extends in the region of the key tip over the key shaft. In other words, the coding path does not extend over the entire key shaft. In an alternative embodiment, however, it is conceivable that the coding path extends over the entire key shaft.
  • the coding path is arranged on the outside of the key shank, in particular on the narrow side and / or the broad side, wherein the coding element comprises a groove with the coding sections, which cooperates with arranged on the outside of the key shaft coding track.
  • the coding element is arranged symmetrically to the key channel.
  • the coding element is thus located centrally between two side walls of the key channel.
  • the width of the coding element is smaller than the width of the key channel, so that a gap is provided between the side wall of the coding element.
  • the coding element projects from at least one side into the key channel. For example, the coding element projects from above and / or below into the key channel.
  • the coding element is designed as a pin, wherein the pin has in particular a circular cross-section.
  • the pin may be rotationally symmetrical or asymmetrical.
  • FIG. 1a shows a sectional view through a rotary lock cylinder according to the invention with inserted key
