Definitions

  • the invention relates to a cylinder lock and a locking device according to the preambles of the independent claims.
  • cylinder locks are known with a cylinder core that can be rotated in a housing about an axis of rotation D, comprising a key channel running in a radial plane R for inserting a coded key.
  • cylinder locks are known in which, in addition to the conventional core and housing pins running in the radial plane R, further core pins are provided which run in a core pin guide on the side of the key channel, i.e. outside the radial plane R.
  • the publication shows EP 2 886 754 A2 such a cylinder lock.
  • the publication shows EP 0 557 606 A1 a cylinder lock with an additional core pin that runs essentially normal to the radial plane R but is centrally arranged.
  • Further generic cylinder locks with core pin guides extending outside the radial plane R are from the publications US 5,819,566 A as well as EP 2 536 902 A1 known.
  • the disadvantage of such cylinder locks is that the core pins running outside the radial plane R have to be moved a long distance due to their eccentric positioning relative to the cylinder core in order to protrude sufficiently into the housing so that a secure locking effect can occur.
  • the object of the invention is to overcome the disadvantages of the prior art.
  • it is the object of the invention to create a cylinder lock in which a sufficient locking effect can be achieved even through small steps on the key.
  • the object of the invention is, among other things, to create a cylinder lock which is as simple as possible and can be produced inexpensively.
  • a cylinder lock according to the invention comprises a cylinder core which can be rotated in a housing about an axis of rotation D, comprising a key channel running in a radial plane R for inserting a coded key.
  • At least one core pin guide extending outside the radial plane R is provided on one side of the key channel. This can be a substantially cylindrical bore or the like.
  • a core pin is provided in the core pin guide, which can be moved along its longitudinal axis in the core pin guide from a blocking position to a release position.
  • the core pin is designed in such a way that the rotation of the cylinder core relative to the housing is released when a key assigned to the cylinder lock is inserted into the key channel. This can be achieved by forming a substantially cylindrical gap (also referred to as a dividing plane) between the cylinder core and the housing, which the core pin blocks or releases depending on the coding of the key.
  • the core pin can be preloaded in the core pin guide by a spring; However, this is not mandatory.
  • the core pin is preferably of essentially cylindrical shape and comprises a core side pointing in the direction of the key channel and designed to query a coding on the key, as well as a housing side pointing in the direction of the housing and designed to engage in a housing recess.
  • At least two locking sections projecting to different extents in the direction of the longitudinal axis are provided on the housing side of the core pin, each with a locking surface that runs essentially normal to the longitudinal axis.
  • the housing side of the core pin is not linear, but essentially step-shaped.
  • the blocking surfaces protrude beyond the cylinder core in the blocking position.
  • the locking sections protrude at least partially, preferably completely, into the housing recess.
  • the locking surfaces of the core pin are preferably flat, smooth and/or without elevations. If necessary, a transition region can be arranged between the locking sections, which in particular runs obliquely to the longitudinal axis of the core pin.
  • both locking surfaces of the core pin protrude into the housing recess, so that movement of the cylinder core relative to the housing is prevented, and in the release position the core pin releases the movement of the cylinder core relative to the housing.
  • the core pin In the release position, the core pin can be arranged in the cylinder core, in particular without any projection and/or completely.
  • a side is designed in a step-like manner can be understood as meaning a side which comprises at least two steps, which are optionally spaced apart by a transition region.
  • the core pin guide can extend transversely, preferably normal to the radial plane R of the cylinder core and can preferably be arranged offset from the axis of rotation D of the cylinder core.
  • the offset of the core pin guide can be, for example, half, a third, a quarter or a fifth of the radius of the cylinder core. Due to the step-shaped design of the housing side of the core pin, the offset can be particularly large and it can even be provided that two or more core pins are arranged in a quadrant of the cylinder core cross section.
  • the core pin may be substantially cylindrical but may have a non-circular cross section such that it is not rotatable in the core pin guide.
  • the core pin can have a shoulder that extends radially outward in sections and is designed to interact positively with a stop in the core pin guide in order to limit the displacement of the core pin in the core pin guide in the direction of the cylinder core.
  • the housing recess has a smaller cross section than the core pin guide, so that the core pin can only penetrate into the housing recess with its locking sections, i.e. the locking surfaces.
  • the core pin can include a release device which is designed such that the core pin in the core pin guide is moved from the blocking position to the release position when a key assigned to the cylinder lock is inserted into the key channel.
  • the release device can preferably be magnetizable and particularly preferably comprise a permanent magnet which is designed to interact with a magnetic coding on the key.
  • the core pin can be moved essentially in the direction of its longitudinal axis in the core pin guide by interacting with the release device.
  • the release device and the core pin can cooperate in such a way that the core pin is moved in the direction of the key channel or in the direction of the housing, whereby the rotation of the cylinder core relative to the housing is released.
  • the release device can be arranged in a recess of the core pin, preferably designed as a blind hole, which is particularly preferably arranged on the core side of the core pin, i.e. adjacent to the key channel.
  • the blind hole can preferably be formed symmetrically about the longitudinal axis of the core pin.
  • a first control surface can be provided on the core side of the core pin, which is flat and runs essentially normal to the longitudinal axis of the core pin. Furthermore, a second control surface can be provided on the core side of the core pin, which is curved or curved along the longitudinal axis.
  • the first control surface on the core side of the core pin can form a first circular ring section.
  • the second control surface on the core side of the core pin can form a second circular ring section. Both circular ring sections can cover the outer circumference of the core side of the core pin.
  • the control surfaces can in particular be arranged concentrically around the recess, preferably the blind hole.
  • the control surfaces can preferably be designed to be offset in steps along the longitudinal axis, so that the second control surface extends further in the direction of the key channel than the first control surface.
  • the second control surface can in particular be designed as a web-shaped scanning extension for scanning a slot-shaped coding on the key. This may make it possible to further increase the security of the cylinder lock, since on the one hand the key must be designed to move the core pin and, on the other hand, must have a coding that can interact with the control surface of the core pin. If necessary, the core pin is only moved by the interaction of the key and the control surface.
  • a housing pin that is preloaded by a spring and interacts with the core pin can be provided in the housing recess.
  • the housing pin can be designed in such a way that it forms a dividing plane between the cylinder core and the housing and releases this when a key assigned to the cylinder lock is inserted into the key channel.
  • At least one spacer plate can be provided between the core pin and the housing pin, so that the rotation of the cylinder core relative to the housing is enabled in two or more positions of the core pin.
  • the spacer plates enable the formation of two or more independent division planes. This makes it possible in particular to use key systems with different key hierarchies for operating the cylinder lock.
  • the spacer plate is also displaced by a displacement of the core pin.
  • the at least one core pin, in particular its housing side, or the at least one spacer plate is brought into a position in which the cylinder core can be rotated relative to the housing.
  • the housing side of the at least one core pin, the housing side of the at least one spacer plate or the separating surface between the at least one core pin and the at least one spacer plate are preferably aligned with the parting line (partition plane) between the cylinder core and the housing, so that a rotation of the cylinder core relative to the housing is possible if necessary .
  • the spacer plate is essentially cylindrical with a longitudinal axis, a front core side and an opposite housing side.
  • the core side can rest on the core pin and the housing side on the housing pin or on another spacer plate.
  • the core side can be in positive engagement with the housing side of the core pin.
  • the core side can preferably be designed essentially step-shaped, in that at least two blocking surfaces are provided on the core side, projecting to different extents along the longitudinal axis and running essentially normal to the longitudinal axis, optionally connected by a transition region.
  • At least one blocking surface of the at least one spacer plate can preferably be flat, smooth and/or raised-free.
  • the steps on the core side of the spacer plate can be formed by the at least two blocking surfaces.
  • a transition region can be arranged between the at least two blocking surfaces on the core side of the spacer plate, which in particular runs obliquely to the longitudinal axis of the spacer plate.
  • the spacer plate in particular its core and/or housing side, is preferably designed in such a way that the spacer plate can be positively connected, in particular to the core pin, in particular to the housing side of the core pin, and/or another spacer plate.
  • the core side of the spacer plate can essentially correspond to the housing side of the core pin.
  • the housing side of the spacer plate can essentially correspond to the core side of another spacer plate.
  • the housing side of the spacer plate can also not be step-shaped, but bent, slanted or rounded.
  • the spacer plate can be guided together with the core pin. This makes it possible for the spacer plate to be non-rotatably movable in the direction of its longitudinal axis.
  • the cylinder lock can also have further query elements for querying any coding on the key.
