Definitions

  • the present invention relates to a key according to claim 1 and a combination of key and lock cylinder according to claim 10.
  • a security key with a high copy security can according to the EP 0 621 384 B1 of the applicant can be achieved by providing the shank of the security key with a control element which is designed as a pin and is slidably mounted in the shank. This control element can be classified with an additional tumbler in the lock cylinder. Such a key cannot be copied with justifiable effort.
  • the present invention is based on the object of specifying a key or a combination of a key with a lock cylinder which is improved over the keys from the prior art.
  • a key for a lock cylinder comprises a key handle and a key shank adjoining the key handle, which extends along a longitudinal axis.
  • the key shank On its outside, the key shank has control recesses, in particular in the form of control bores, for arranging tumblers on the lock cylinder.
  • the key also has at least one query surface on the key side, with which the key strikes a query surface on the lock cylinder side. Furthermore, at least one of the query surfaces on the key side is inclined at an angle of intersection to a straight reference line oriented parallel to the longitudinal axis.
  • a query surface By arranging a query surface at an angle of intersection with the said reference straight line, there is an advantage that a query surface can be provided that allows a more extensive query.
  • the query is very simple and reduced to the essential features, which makes the key easy to use.
  • said query surface is always placed in the same position relative to the key shank in a set of keys.
  • the interrogation surfaces on the locking cylinder side are arranged at different positions in a locking cylinder set.
  • said query surface is placed at different locations relative to the key shank.
  • the interrogation surfaces on the lock cylinder side are in a lock cylinder set arranged in different positions; or the interrogation surfaces on the lock cylinder side are arranged at the same positions in a lock cylinder set.
  • the query area is pierced by the reference line.
  • the angle between the query surface and the reference line is the claimed intersection angle.
  • the angle of intersection also results as the difference between 90° and an angle between a surface normal to the query surface, which extends through the intersection between the query surface and the reference line, and said reference line.
  • the lock cylinder is preferably a rotary lock cylinder.
  • the key is preferably designed as a reversible key.
  • the key strikes with the at least one key-side query surface against the lock cylinder-side query surface when the key shank is fully inserted in the key channel of the lock cylinder. If the key is intended for the lock cylinder, the key is in the correct position in the lock cylinder and the tumblers can be actuated. If the key is not provided for the lock cylinder, the key is not in the correct position in the lock cylinder and the tumblers cannot be actuated. Accordingly, the query surfaces also act as stop surfaces for the key.
  • two query surfaces are preferably arranged which are inclined at an angle of intersection, the query surfaces being arranged symmetrically with respect to a first reference plane which extends through the longitudinal axis and at right angles to the narrow side of the key shank.
  • This arrangement has the advantage that when the key is pushed in and in particular when the intended end position is set, the key is balanced with respect to the key channel.
  • the value of the angle of intersection of one query surface to the reference axis is the same as the value of the angle of intersection of the other query surface to the reference axis.
  • the two query surfaces Seen from the longitudinal axis, run such that the distance between the two query surfaces increase with increasing distance in one direction and decrease with increasing distance in the other direction.
  • the two angularly inclined sensing surfaces form a first pair of sensing surfaces, a second pair of sensing surfaces being symmetrically disposed with respect to a second reference plane extending through the longitudinal axis and perpendicular to said first reference surface.

  • the further query surface preferably connects the query surfaces which are arranged at an angle at an angle of inclination to one another.
  • the surface normals of said query surfaces are preferably arranged in such a way that they lie in a common plane, with the plane running parallel to the longitudinal axis.

  • This arrangement has the further advantage that said query surfaces can be produced very easily, for example with an end mill whose central axis is aligned transversely to the longitudinal axis.
  • the query surfaces can be produced in one setting.
  • the cutting angle is greater than 0° and less than 90°, in particular that the cutting angle is in the range from 30° to 60°.
  • the at least one query surface or surfaces are preferably at the rear arranged at the end of the key shank.
  • the query surfaces are arranged in a transition area from the key shank to the key handle.
  • a recess which extends into the key shank is preferably arranged between the key shank and between the query surfaces.
  • the at least one query surface or surfaces preferably extend outwards from the narrow side of the key shank.

  • the key is not widened by the query area.
  • a lock cylinder and a key are characterized in that the lock cylinder has a stator, a rotor which is mounted in the stator so that it can rotate about a central axis and has a key channel, with tumblers being provided between the stator and the rotor, which can be arranged through the control recesses on the key shank, and wherein the rotor has the at least one interrogation surface on the locking cylinder side.
  • the at least one interrogation surface on the lock cylinder side is provided for interrogating said interrogation surface arranged at the intersection angle to the reference straight line and/or for interrogating other interrogation surfaces arranged on the key.
  • the interrogation surface arranged on the rotor on the locking cylinder side works together with the interrogation surfaces mentioned arranged on the key.
  • the interrogation surface on the locking cylinder side provides a stop for the stop surface on the key side. If the key is an authorized key acts, the key shank comes to lie in the key channel in the exact position relative to the tumblers and the tumblers can be classified. If it is an unauthorized key, the key shank will not be in the correct position and the tumblers cannot be classified.
