Definitions

  • the invention relates to a flat key for a cylinder lock with a coded surface running along the longitudinal extent of the flat key, with control points being provided at scanning positions on the surface for coding, which are connected by a control groove, and with coding features being provided at the control points for querying in the cylinder lock .
  • Such flat keys with control grooves running along the longitudinal extent are known from the prior art.
  • the cylinder lock locks as soon as all control slides of the cylinder lock are moved into the intended position through the control groove on the flat key.
  • the publications show WO 2017/006356 A1 , AT 396 501 B and EP 2 626 488 A2 Flat keys with control points connected by control grooves or cylinder locks designed to query such flat keys.
  • the object of the invention is therefore to solve these and other problems of the generic flat keys and associated cylinder locks.
  • the coding feature at a first control point encloses a different angle with the central longitudinal plane of the flat key than the coding feature at a second control point.
  • the coding features include surfaces or projections whose angle to the central longitudinal plane of the flat key can be determined.
  • control groove has a torsion section at least between the first control point and the second control point.
  • a torsion section of the control groove has the advantage that the free cross section of the control groove in the longitudinal direction of the flat key is not constant, for example rectangular, but rather rotates. This causes control slides in a cylinder lock that does not belong to the flat key to get caught on the changed cross section of the control groove, thus preventing the key from being pushed into the key channel.
  • the torsion section also has the advantage that the rotation of the control groove cannot be determined directly from a simple photograph of the flat side of the key.
  • control groove in the torsion section has a cross section which is rotated relative to the cross section of the control groove outside the torsion section by an angle in the range of -45° to +45°, preferably -30° to +30°. This ensures that even with very small control slides, there is enough material to ensure that an unauthorized key is blocked in the key channel of the cylinder lock.
  • the angle of the coding feature to the central longitudinal plane of the flat key in the torsion section changes along the longitudinal extent from a first angle value in the area of the first control point to a second angle value in the area of the second control point.
  • the change can preferably take place linearly.
  • the angle of the coding feature to the central longitudinal plane of the flat key changes suddenly in the torsion section, for example in a step-like manner. This ensures that the control slides are guided smoothly in the control groove without blocking due to contamination or manufacturing inaccuracies.
  • the first angle value is in the range of -45° to 0°, preferably in the range of -30° to 0°
  • the second angle value is in the range of 0° to 45°, preferably in the range of 0° up to 30°, each measured from the central longitudinal plane.
  • At least one further control groove with control points is provided on the coded surface in addition to the control groove, the coding features of which have essentially the same angle to the central longitudinal plane of the flat key at all control points.
  • this further control groove does not have a torsion section.
  • the rotated and non-rotated control grooves have different depths and/or different widths.
  • the coding feature is designed as the groove base of the control groove.
  • the use of the groove base as a coding feature has the advantage that it can be easily scanned by a conventional spring-loaded control slide, especially since conventional control slides are usually designed to scan the groove base.
  • control slides of an associated cylinder lock must have appropriately designed scanning elements in order to be able to follow the rotating groove base of the control groove along the longitudinal extent to the intended control point when the key is inserted into the key channel, without blocking.
  • the side surfaces of the control grooves always enclose a substantially right angle with the groove base of the control grooves. This results in a rectangular cross-sectional shape of the control groove that is comparatively easy to produce in practice.
  • the coding feature is designed as a material web running in the control groove along the longitudinal extent of the flat key. The use of a material web offers an alternative to using the groove base, which is more complex to produce, but requires the use of special scanning elements with a correspondingly designed exemption, so that an additional possibility for variation is made available.
  • the material web can be arranged essentially centrally in the control groove.
  • the material web can, for example, have a width that essentially corresponds to a third of the width of the control groove. This ensures that the material web can be reliably scanned and that the material web and the remaining lateral areas of the control groove are protected against contamination.
  • the material web projects beyond the cross section of the key profile.
  • the overhang of the material web can be comparatively small, for example 1/10 to 1/3 of the width of the control groove, in order to prevent the material web from being exposed to excessive loads and breaking off or being bent when the flat key is handled.
  • the side surfaces of the material web enclose a substantially right angle with the groove base of the control grooves.
  • the coded area can be a flat side of the flat key.
  • the coded area can also be a front side of the flat key.
  • combinations are also possible, with one coded area being provided on the flat side and one on the front side of the flat key.
  • the invention further relates to a cylinder lock for a flat key according to the invention.
  • a cylinder lock for a flat key according to the invention.
  • Such a cylinder lock comprises a key channel with at least one side and scanning positions provided along the longitudinal extent of the key channel, at least one control slide being provided at each scanning position, and each control slide comprising at least one query element for querying a coding feature of a control groove at a control point of the flat key.
  • the key channel is usually part of a cylinder core that is rotatably arranged in a cylinder housing.
  • the control slides When locked, the control slides prevent the cylinder core from rotating in the cylinder housing. It can also be provided that the control slides interact with one or more locking elements that counteract rotation of the cylinder core in the cylinder housing.
  • the control slides When an authorized key is inserted, the control slides are moved into a release position by their query elements engaging with coding features on the flat key, which are arranged at different positions. In the release position, the control slides or the locking elements actuated by the control slides enable the cylinder core to rotate in the cylinder housing.
  • At least two control slides are provided, each of which comprises a first interrogation element and a second interrogation element, the first interrogation element enclosing a different angle with the central longitudinal plane of the key channel than the second interrogation element.
  • One and the same control slide therefore comprises two different interrogation elements, the interrogation elements of these at least two control slides being designed differently from one another.
  • control slide is able to intervene in differently shaped coding features at different scanning positions of the flat key.
  • conventional control slides that only have a single query element would block when the key is inserted on coding features of the control groove that are not designed for the single query element.
  • the first query element is designed as a first query surface and the second query element is designed as a second query surface on a scanning cam of the control slide. This allows the control slide to engage in a first surface and a second surface of the control groove and scan corresponding coding features.
  • the first interrogation surface and the second interrogation surface are designed as end faces of the scanning cam for engagement in the groove base of the control groove of the flat key.
  • the first interrogation surface of the control slide can thus engage in the groove base at the first control point, and the second interrogation surface of the control slide in the groove base at the second control point. This ensures that the control slide can follow the changing orientation of the groove base of the control groove along the longitudinal extent of the flat key.
  • the first interrogation surface and the second interrogation surface are designed as side surfaces of a scanning groove of the scanning cam for engagement in a material web of the control groove of the flat key.
  • a material web is provided in the control groove, and the control slide is guided along the material web in the control groove.
  • the material web can change its angle to the central longitudinal plane of the flat key in a torsion section, so that the material web has a different inclination to the central longitudinal plane of the flat key at a first control point than at a second control point.
  • control slide can also follow the control groove in the torsion section, while conventional control slides would block.
  • At least one further control slide is provided, which includes a first query element, but not a second query element.
  • Such known control slides can be combined with the control slides designed according to the invention in order to create an additional number of possible variations.
  • the first interrogation surface runs essentially parallel to the central longitudinal plane of the key channel.
  • the second interrogation surface can enclose an angle in the range from -45° to +45°, preferably in the range from -30° to +30°, but also, for example, in the range from -15° to +15° with the central longitudinal plane.
  • the cylinder lock comprises a cylinder core in which recesses with a preferably circular cross section are provided parallel to the central longitudinal plane and spaced therefrom at the scanning positions, the control slides being movably mounted in the recesses.
  • the control slides can be mounted in the recesses without preload, so that when the flat key is inserted they can be actively guided into a release position by positive engagement in control grooves of the flat key.
  • the invention further extends to a system comprising at least one key according to the invention and at least one cylinder lock according to the invention.
  • Fig. 1 shows a view of an embodiment of a flat bowl 1 according to the invention from the side.
  • the flat key 1 comprises a coded surface 2 running along its longitudinal extent.

Between a first control point 3' and a second control point 3", a torsion section 11 is provided, in which the control groove 6 changes its orientation to the central longitudinal plane of the key . As a result, the coding feature at the first control point 3' has a different angle to the central longitudinal plane of the key than the coding feature at the second control point 3".
  • the control groove 6 has a cross section which is rotated relative to the cross section of the control groove 6 outside the torsion section 11 by an angle in the range of -45° to +45°, preferably -30° to +30°.
  • the angle of the coding feature to the central longitudinal plane 8 in the torsion section 11 changes linearly along the longitudinal extent from a first angle value in the area of the first control point 3 'to a second angle value in the area of the second control point 3".
