Furthermore, the present invention relates to a locking system with such a lock cylinder and a key. Furthermore, the present invention relates to a method for unlocking a lock cylinder.
  • the publication WO 03/064795 A1 shows a lock cylinder with a cylinder housing, a rotatably mounted therein cylinder core, which has a keyway for insertion of a key whose rotation is normally locked by means of a rotation joint between the cylinder core and cylinder housing intersecting tumbler.
  • the tumbler element is designed as a key insertion direction of a blocking in a release position displaceable locking member which cooperates in its displacement of the locking in the release position with a transversely slidable key insertion direction motion transmission member.
  • the motion transmission member is a pin which is engageable by insertion of the key from one of the locking position of the locking part corresponding to non-operative position in a displacement of the locking member in the release position enabling operative position.

  • the "Axialzuroisselement” is a tumbler, which is offset from its locking position to its release position substantially parallel or parallel to the key insertion direction. It is therefore offset in the axial direction of the lock cylinder. Therefore, the tumbler element is called an "axial tumbler element" in the context of the present application. In its release position, it allows a rotational movement of the cylinder core in the cylinder housing. As explained in detail below, this is made possible by the fact that it can escape in the release position upon rotation of the cylinder core in the cylinder housing in a receiving recess of the cylinder core.
  • the Axialzuroisselement is a rod element of a locking bar. The locking rod has two relatively movable rod elements.
  • the rod elements may be identical.
  • the rod elements may have a rotationally symmetrical cross section. While previously a locking bar was provided which had to be supported by a spring on a wall of the cylinder core, now the two rod elements can be supported relative to each other moved. This makes it possible to provide the locking bar as a prefabricated component arrangement, which makes the installation easier and significantly reduces or eliminates the risk of losing individual parts of the arrangement. The simpler production and due to the rotational symmetry of the elements involved lower tooling costs make the production and assembly overall more cost effective.
  • the lock cylinder further has a movement transmission element movable transversely to the key insertion direction, which interacts with the key and with the axial locking element in order to displace the axial locking element substantially parallel to the key insertion direction, in particular parallel to the key insertion direction.
  • the Axialzu insectsselement is obliquely controlled by the motion transmission element.
  • both the motion transmission element and the Axialzuletselement have a conical tip. These conical tips then abut each other, so that the oblique flanks can bring about a conversion of the direction of movement.
  • the lock cylinder can have exactly one Axialzuletselement. But the lock cylinder can also have more than one Axialzuletselement.
  • a plurality of tumbler elements has at least one axial tumbler element. In other words, at least one of the plurality of tumbler elements is an axial tumbler element. If a plurality of Axialzunnensettin provided exactly one of Axialzunnensetti may be formed by a rod member of the locking bar. It can, if a plurality of Axialzuienss instituten is provided, but also several or all of these Axialzuienssetti be formed by a rod member of a locking bar. It can also be provided a plurality of locking rods in the lock cylinder, of which in each case exactly one rod element or each of which a plurality of rod elements each form an Axialzuiensselement.
  • this locking system has the same advantages as the lock cylinder according to the first aspect of the invention.
  • the rod elements are identical and rotationally symmetrical.
  • the rod elements are then offset relative to each other parallel to their rotational symmetry axis.
  • the key is fully inserted into the keyway and thereby the Axialzuroisselement parallel to its axis of rotational symmetry from a locking position relative to the other rod member in its release position is offset.

  • the Axialzuroisselement or that the Axialzuroisselement forming rod member may be biased in its locking position spring. It is supported by means of the spring element on the other rod member. Spacing the Axialzuroisselements in the release position then causes a compression of the spring element. This then stores elastic return energy. If the key is withdrawn from the lock cylinder, then the Axialzuroisselement can be returned by means of the stored spring energy back into the locked position.
  • the other of the rod elements can be supported on the cylinder core. In the rod elements, however, suitable contact surfaces for the spring element can be provided, so that its operation is associated with only a small risk of tilting or improper compression of the spring element.

  • the locking bar has a guide pin which extends into each of the two rod elements and a movement of the two rod elements relative to each other.
  • the spring element in particular the spring element designed as a helical spring, can then extend around the guide pin between the rod elements. In this way it is further ensured that the spring element can not be lost.
