Definitions

  • the invention relates to a cross-sectional profile for a flat key or the key channel of a cylinder lock, a flat key with such a cross-sectional profile, and a cylinder lock with a key channel for receiving such a flat key.
  • Flat keys are known from the prior art which have coded side surfaces with longitudinal ribs or longitudinal grooves running in the longitudinal direction of the key shaft.
  • the cross-sectional profile of the key shaft defines a key profile with two opposite side surfaces.
  • the key channel of a cylinder lock that fits this flat key must consequently have a key channel profile which allows the flat key to be inserted into the key channel; however, the key channel profile does not necessarily have to be identical to the key profile.
  • a different design of the key profile between different key families is referred to as profile variation and allows key hierarchies to be defined for hierarchically lockable locking systems.
  • profile variation allows key hierarchies to be defined for hierarchically lockable locking systems.
  • some cylinder locks can have a key channel profile that allows the introduction of various different key profiles, while other cylinder locks only allow the introduction of a specific key profile.
  • the profile variation is usually independent of the actual coding of the key through the key features unique for each key, which are formed, for example, by locking notches, incisions or magnetic elements and are queried in the lock using appropriate scanning means, for example housing and core pins.
  • scanning means for example housing and core pins.
  • a major abuse scenario with such cylinder locks is what is known as electric picking.
  • electric picking a wire is inserted into the keyway and set in motion up and down by an electric motor. The wire strikes the scanning means, for example the core pins, and sets them and consequently also the housing pins into vibration, so that the dividing plane between the cylinder core and the housing is released. This allows unauthorized persons to open the cylinder lock.
  • DE 101 34894 A1 shows a generic key profile for flat keys, in which the profile variations are formed by providing or omitting surface sections arranged in a grid-like manner in the cross-sectional profile, which are formed by sinusoidal profiling lines.
  • the profiling lines run over the center line of the keyway so that the wire of the electric picking tool gets caught on the remaining surface sections.
  • Such a key profile is also referred to as a paracentric key profile.
  • this inevitably removes a lot of material from the key and greatly reduces the stability of the key.
  • the object of the invention is to overcome these and other disadvantages of the prior art. Alternative designs for defining profile variations are to be made available to those skilled in the art.
  • the object of the invention is, among other things, to create a key profile for flat keys and matching cylinder locks, which is as simple as possible and inexpensive to manufacture, is robust against mechanical loads, and also offers protection against misuse, in particular so-called electric picking.
  • a cross-sectional profile according to the invention for a flat key or the key channel of a cylinder lock comprises a back surface, a first side surface and a, in particular opposite, second side surface.
  • the side surfaces extend in a vertical alignment to the back surface and are arranged offset from one another by a distance which may vary along their extension.
  • the envelope of the cross-sectional profile forms a preferably essentially rectangular basic profile. In this case, however, deviations from the rectangular shape are provided according to the invention in sections, that is, the cross-sectional profile can also protrude in sections over the basic profile.
  • the side surfaces of the cross-sectional profile each run at least in sections along sinusoidal profiling lines, the center lines of the profiling lines each lying within the basic profile.
  • sinusoidal profiling lines can be easily produced and varied, for example by changing the phase position of the sinusoidal curves with respect to one another.
  • the side surfaces each run at least in sections along a single sinusoidal profiling line.
  • a sinusoidal profiling line is defined for each side surface, along which the side surfaces run at least in sections.
  • Such a cross-sectional profile can on the one hand form the cross-section of a profiled flat key. On the other hand, it can also form the cross section of the key channel in the rotatable core of a cylinder lock.
  • the center lines of the profiling lines are spaced apart and run parallel to one another, so that their spacing corresponds approximately to the spacing of the side surfaces.
  • the phase shift of the profiling lines is therefore approximately equal to zero, and their spacing corresponds approximately to the thickness of the key or the key channel.
  • the center lines of the profiling lines do not run parallel to one another.
  • the profiling lines can run at an angle ⁇ to the central plane of the basic profile, which is preferably in the range of approximately 5 °, the profiling lines approaching one another linearly along their extension from the back surface.
  • the key is wider in the area of its back surface than in the area of its key face or the key channel is narrower in the area of the center of the cylinder core than in the area of the outer circumference of the cylinder core.
  • any number N, preferably two, sinusoidal variation lines are provided which cross the profiling lines, the side surfaces for forming variation ribs running at least in sections along one of the variation lines. That is, the intersection of the variation lines with the profiling lines form variation ribs.
  • N preferably two, sinusoidal variation lines
  • the variation ribs are not key-specific codings.
  • the center lines of the variation lines preferably lie within the basic profile.
  • a number N1, preferably two, sinusoidal first variation lines for forming first variation ribs are provided on the first side surface, which are shifted by a phase offset of approximately 3607N1, particularly preferably approximately 180 °
  • a number N2, preferably two, sinusoidal second variation lines for forming second variation ribs are provided on the second side surface, which are shifted by a phase offset of approximately 3607N2, particularly preferably approximately 180 °.
  • two variation lines can be provided on each of the two sides, each of which is shifted by 180 ° to one another.
  • the center lines of the variation lines can coincide and lie in the center plane of the basic profile.
  • the center lines of the variation lines can also lie outside the center plane of the basic profile.
  • the center lines of the variation lines can run parallel to the median plane of the basic profile, but they can also run at an angle ⁇ to the median plane of the basic profile, which is preferably in the range of about 5 °, and they extend linearly from the back surface.
  • the profiling lines and the variation lines preferably have essentially the same period duration T.
  • a first variation line can have a phase shift in the range from approximately 75 ° to approximately 105 °, preferably approximately 90 °, with respect to a first profile line.
  • the amplitude of the profiling lines is preferably at least half the distance between the side surfaces. In other words, the amplitude is at least half the material thickness of the key shaft or at least half the width of the key channel. This ensures that the cross-sectional profile is paracentric, that is to say that the side surfaces protrude in sections over the center line of the basic profile and thus make picking of the lock more difficult.
  • the profiling lines and the variation lines can have essentially the same amplitude. However, it can also be provided that the profiling lines and the variation lines have a different amplitude, at least in sections. In this case it can be provided that the profiling lines in sections protrude beyond the basic profile, that is to say the envelope of the cross-sectional profile. On the key, this design is expressed in a protruding profile rib, in the keyway in a correspondingly wide profile groove.
  • the invention also relates to a flat key with a cross-sectional profile according to the invention.
  • a flat key comprises two longitudinally profiled key side surfaces running at least in sections along the profiling lines and optionally the variation lines of the cross-sectional profile, a key back surface and an optionally coded key face surface.
  • the profile ribs and variation ribs extend along the entire shaft on both sides of the flat key.
  • the flat key can have a key head and a key point, wherein in possible embodiments of the invention the amplitudes of the profiling lines and the variation lines in the area of the key point are smaller than in the area of the key point.
  • the flat key is narrower in the area of its tip than in the area of its bow, but no changes are provided for in the positioning and the course of its profile ribs and variation ribs; only the amplitudes of the profiling and variation lines are reduced.
  • the flat key can be made about 20% to about 80% narrower in the area of the key tip than in the area of the key head.
  • the narrower area can extend, for example, over a distance of 20% to 50% of the length of the flat key, wherein the transition to the thicker area can be formed abruptly or smoothly.
  • the amplitudes of the profiling lines and the variation lines of the cross-sectional profile of a flat key according to the invention in the area between the key tip and the key head are only reduced in sections by in particular about 20% to 80%.
  • Those points at which the amplitudes are reduced can preferably be areas of scanning positions at which the flat key has codes for interrogation in the associated cylinder lock.
  • the flat key is therefore narrower in sections, so that the scanning elements in the associated cylinder lock must be designed accordingly in order to be able to scan the codes on the narrow key shaft. This is independent of the design of the key channel, which, in order to enable the flat key to be inserted, must be dimensioned with amplitudes of the profiling and variation lines that at least correspond to or exceed those of the flat key.
  • the invention further relates to a cylinder lock with a key channel for receiving a flat key, the key channel being designed with a cross-sectional profile according to the invention.
  • the key channel consequently comprises two side surfaces running at least in sections along the profiling lines and optionally the variation lines of the cross-sectional profile.
  • at least one side surface of the key channel has a catching cap in order to prevent or make electric picking more difficult.
  • the catch cap can be designed as a sinusoidal flint cut of the side surface around a base line. This means that the side surface of the key channel does not run exactly along the specified sinusoidal profiling line or variation line, but rather has an undercut.
  • This undercut can preferably extend along the entire length of the key channel, that is to say over all scanning positions in the cylinder core, in order to make electric picking more difficult at each scanning position.
  • the predefined profiling line or the variation line of a side surface can serve as the base line of the sinusoidal undercut.
  • the configuration of the sinusoidal undercut is preferably selected in such a way that it can be well integrated into the predetermined profiling line or variation line of the side surface.
  • the amplitude of the sinusoidal undercut can, for example, be less than the amplitude of the profiling line, for example approximately 20% to 50% of the amplitude of the profiling line.
  • the base line can run at an angle of approximately 60 ° to approximately 90 ° to the center plane of the basic profile of the cross-sectional profile. This angle depends primarily on the positioning of the catching cap along the profiling line.
  • At least one core pin can be provided in a cylinder lock according to the invention, which is hipped-shaped at its end protruding into the key channel and has a scanning surface.
  • the scanning surface can be designed symmetrically or optionally also asymmetrically to the longitudinal axis of an essentially cylindrical base body of the core pin.
  • the scanning surface can run linearly essentially along the entire diameter of the cylindrical base body.
  • the scanning surface can also run linearly along a section of the diameter of the cylindrical base body.
  • Different core pins can also be provided in the cylinder lock, for example core pins with a symmetrically designed scanning surface and core pins with an asymmetrically designed scanning surface.
  • the invention also relates to a locking system, comprising one or more flat keys according to the invention and one or more cylinder locks according to the invention.
  • a locking hierarchy is formed by different, hierarchical design of the cross-sectional profiles of the flat keys and that of the cross-sectional profiles of the key channels.
  • individual cylinder locks can be designed with key channels that allow only selected flat keys to be inserted, and other cylinder locks can have key channels in which all flat keys can be inserted (for example by having all the variation ribs milled out).
  • the design of such hierarchical key families is fundamentally known to the person skilled in the art.
  • the flat key has a cross-sectional profile in which the center lines of the variation lines lie outside the center plane of the basic profile
  • the cylinder lock comprises at least one core pin which is hipped-shaped at its end protruding into the key channel to scan the codes of the flat key lying outside the center plane of the base profile.
