Definitions

  • the invention relates to a key with a key bow and a key shank. Furthermore, the invention relates to a lock for receiving a lock according to the invention
  • the lock comprises a lock cylinder with a cylinder core. Furthermore, the invention relates to a locking system with a key according to the invention and a lock according to the invention.
  • a key with a movable pin and a security rotary cylinder and a lock equipped with it are already known.
  • a key for a security rotary cylinder is to be specified, in which copying of a key equipped with it is made more difficult by a movable handle and the user is given increased security.
  • the CN 1 865 639 A discloses a burglar-proof lock cylinder and a key provided for the lock cylinder, with a key bow and a key shank.
  • the lock cylinder has an I-shaped opening.
  • the matching key also has an I-shaped basic profile.
  • the bow of the key is twisted by 180°, and in the direction of the tip of the key, the cross-section of the key shank protrudes in sections beyond the basic cross-section.
  • the U.S. 424,412 discloses a key in which the key shank is twisted so that it can contact a row of locking pins within the lock at their otherwise smooth edge. At the end, the cross-section of the key shank aligns itself again.
  • U.S. 1,280,633 A discloses a locking system that relies on the key being spindle or spiral shaped.
  • WO 02/88497 A1 and CN 1 963 122 A show very similar embodiments of keys.
  • the CN 101 025 060 A shows a key body which is twisted through a torsion angle of 180° and whose cross section is congruent in the area of the beginning of the shank and at the tip of the shank.
  • the object of the invention to specify a further developed key with a key bow and a key shank, which initially creates a large number of coding options. Furthermore, it is the object of the invention to specify a further developed lock which is further developed in terms of protection against manipulation. Furthermore, it is an object to specify a further developed locking system that includes a key according to the invention and a lock according to the invention.

  • the key shank has at least one profile element, the profile element likewise having a torsion in the torsion section.
  • a section that is created by twisting the section is referred to as a torsion section.
  • the section is twisted around the longitudinal axis of the key shank. Accordingly, the torsion section describes a twisted section of the key shank, the torsion section being created by the effect of a torsional moment.
  • the torsion section forms an additional coding option in connection with the key shank. It is possible for the key shank to have the stated basic cross section both before the torsion section is formed and after the torsion section is formed.
  • the basic cross-section is formed in those sections of the key shank that are not twisted or on which no torsional moment acts or did not act.
  • the torsion section is preferably flattened or flattened prior to forming, i.e. prior to its actual manufacture.
  • the key shank is flattened or flattened in a first step in the section that is later to have a torsion section, with the flattened or flattened section being rotated or twisted about the longitudinal axis of the key shank in a second step.

  • the torsion section of the key shank is a cold-formed torsion section.
  • a key shank which is straight or planar in particular along the longitudinal axis.
  • the formation of the torsion section in particular the action of a torsion moment on this section of the key shank, takes place, for example, by cold forming.

It is possible for the longitudinal groove to extend all the way to the bow of the key. It is also possible for a spaced section to be formed between the bow of the key and the end of the longitudinal groove. Due to the formation of a torsion section on the key shank, the profile element, in particular the longitudinal groove in the torsion section, also has a torsion. In other words, the profile element is bent around the longitudinal axis.
  • the key shank can have at least two profile elements. These profile elements run parallel to one another in a first section starting from the key bow. In a/the subsequent torsion section, the profile elements, in particular the longitudinal grooves, are twisted about the longitudinal axis of the key shank.
  • the profile elements, in particular the longitudinal grooves are preferably arranged in the manner of a double helix.

Accordingly, the tip of the key is likewise arranged rotated about the longitudinal axis of the key shank. The cross section of the key tip can protrude beyond the basic cross section of the key shank. This in turn represents another coding option.
  • the tip of the key shank does not necessarily have to be pointed. It is also conceivable that the tip of the key is designed as a flat surface.
  • At least the key shank can be made of elastic material, in particular spring steel or polyurethane, particularly preferably PUR D 44. Such an elastic material causes the key shank to be torsionally adapted when inserted into a cylinder core.
  • the key shank can be rotatably mounted in the key bow.
  • the key shank prefferably has different diameters or different cross-sections.
  • the different cross sections can also be formed in sections of the key shank that do not have a torsion section.

  • the geometry of the torsion section may differ in pitch and/or arc length and/or pitch and/or torsion.
  • a further aspect of the invention relates to a lock for receiving a key according to the invention, the lock comprising a lock cylinder with a cylinder core.
  • At least one decoding element is formed in the cylinder core, which at least in sections has an arcuate, in particular helical, contour or is arranged at least in sections on an arcuate, in particular helical, path.
  • the helical contour can also be referred to as a curved contour.
  • the helical track can also be referred to as a curved track.

  • the torsion section of the key shank is matched in the lock by elements of complementary design, in particular decoding elements.
  • a geometric match between the key shank, in particular the torsion section of the key shank, and the cylinder core of the lock allows the key shank to be inserted spatially with a precise fit into the cylinder core. This makes it possible to enable a spatial, i.e. at least three-dimensional, coding function.
  • the lock can also have a coupling element that scans the tip, in particular the tip associated with the torsion section.
  • the coupling element is preferably designed in such a way that the tip of the key shank can be scanned over different lengths.
  • the decoding elements, in particular the scanning elements, are arranged radially with respect to the basic profile of the cylinder core.
