Definitions

  • the invention relates to a key for a cylinder lock and a system comprising such a key and a cylinder lock.
  • the cylinder lock comprises a housing with spring-loaded housing pins and a cylinder core rotatably mounted in the housing with a key channel and core pins protruding into the key channel, wherein the core pins have scanning extensions at their ends protruding into the key channel for querying codes of the key.
  • Such cylinder locks are known.
  • the codes on the key are usually formed by the depth of cut millings.
  • AT 506 955 B1 such a cylinder lock as well as a flat key designed for it with cut millings on both the front surface and the side surface of the key, and correspondingly designed core pins.
  • Conventional keys and conventional cylinder locks are DE 9 409 290 U1 , the BE 460 924 A , the EN 10 2015 008 016 A1 , the DE 92 11 896 U1 , the DE 94 03 191 U1 and the WO 2010/017941 A1 known.
  • the DE 9 409 290 U1 discloses a key according to the preamble of claim 1. From the above-mentioned EN 10 2015 008 016 A1 Keys are known, whereby the width of the notch milling allows conclusions to be drawn about the depth of the notch milling.
  • the codes are usually formed by milled cuts, the depth of which is directly proportional to the recess formed on the surface of the key.
  • the recess formed on the surface can be easily measured, for example by high-resolution photography, so that the depth of the milled cut and thus the code of the key can be quickly determined.
  • the object of the present invention is in particular to eliminate these and other problems of conventional keys and cylinder locks and to realize a key and a cylinder lock which, on the one hand, offers codings with sufficient variation possibilities and, on the other hand, makes rapid copying by photographing the codings more difficult.
  • a key according to the invention has codings of different depths that taper from a surface of the key in the direction of a longitudinal axis of the key.
  • taper means that the cross section of the coding, which is implemented as a hole or milled recess, for example, reduces in the direction of the longitudinal axis of the key, i.e. normal to the longitudinal extension of the key.
  • the longitudinal axis of the key in this context is the axis that runs parallel to the key channel of the cylinder lock when a key is inserted into a cylinder lock.
  • the surface mentioned can be a front surface, a side surface, or any other surface of the key, for example a groove base formed by a groove.
  • At least two codes are provided, the extent of which on the surface of the key is essentially the same and which differ in their depth and in the rise of their taper in the direction of the longitudinal axis of the key. This ensures that the key interacts with any core pins of the associated cylinder lock, although the extent of the code on the surface of the key cannot be used to determine its slope and depth.
  • the codes can, for example, be designed as holes so that the extent on the surface is essentially circular, or as cut millings so that the extent on the surface of the key is essentially rectangular. Other types of coding can also be provided according to the invention.
  • the key is designed as a flat key, with the codings being provided on at least one front face of the flat key. According to the invention, it can also be provided that the key is designed as a flat key, with the codings being provided on at least one side face of the flat key. Combinations of these are also provided according to the invention, so that codings according to the invention are provided on both the front face and the side face of the key.
  • the said surface of the key can be flat, curved, arched, convex, concave or of any shape.
  • the surfaces can be arranged at right angles, but it can also be provided that the surfaces enclose any angle.
  • the codings on the surface of the key are connected by a groove that runs continuously parallel to the longitudinal axis of the key without forming edges.
  • the groove also has the advantage that the cut millings in the groove are laterally concealed by two ribs of remaining key material, which makes it even more difficult to copy the key.
  • the codings are designed as essentially conical holes, the cross sections of which essentially form isosceles triangles, wherein at least two conical holes are provided, the cross sections of which essentially define isosceles triangles with different base angles. For example, base angles of 45°, 35° and 20°.
  • the cross-sections of the codings can also form essentially isosceles trapezoids.
  • the codings are designed as elongated incision millings, the cross sections of which essentially form circular arc sections, with at least two incision millings being provided, the cross sections of which essentially define circular arc sections with different radii of curvature.
  • the incision millings can of course also have a different curved shape, for example the shape of an elliptical section.
  • the cut-outs are arranged parallel to the longitudinal axis of the key, with at least two cut-outs being arranged at different normal distances from the longitudinal axis of the key. This provides a further possibility for varying the coding. In addition, to increase the variation options, it can also be provided that the cut-outs have different widths, i.e. different extensions normal to the longitudinal axis of the key.
  • a key according to the invention can in principle be used with a conventional cylinder lock, since conventional scanning elements of a cylinder lock are able to query the depth of the key's coding.
  • the invention also extends to a system with a key according to the invention and a cylinder lock.
  • Such a cylinder lock comprises, in a known manner, a housing with spring-loaded housing pins and a cylinder core rotatably mounted in the housing with a key channel and core pins projecting into the key channel, which have scanning extensions on their ends projecting into the key channel for querying the coding of a key.
  • the scanning extensions taper in the direction of the key channel, with at least two core pins being provided which have the same extension, in particular the same diameter, but whose scanning extensions differ in the increase of their taper.
  • taper means that the cross section of the core pins tapers in the direction of the key channel, i.e. perpendicular to the Alignment of the keyway, reduced.
  • the extent of the taper of the scanning extensions cannot be determined from the extent of the key's coding on the surface.
  • the codings on the key have the same extent on the surface of the key, but differ in their depth and the extent of their taper.
  • the core pins can have a circular cross-section with an identical diameter in a known manner.
  • the scanning extensions of the core pins can be designed in the shape of a cone-pyramid starting from the core pins. However, embodiments of the invention with scanning extensions of any shape are also provided, for example scanning extensions that protrude into the key channel in an elliptical or circular segment-shaped manner starting from the core pins.
  • the cross section of the scanning extensions forms a substantially isosceles triangle, wherein at least two core pins are provided, the scanning extensions of which define isosceles triangles with different base angles in cross section. For example, base angles of 45°, 35° and 20° can be provided.
  • the cross section of the scanning extensions can also form a substantially isosceles trapezoid.
  • the cross section of the scanning extensions essentially forms a circular arc section, wherein at least two core pins are provided, the scanning extensions of which have circular arc sections with different radii of curvature in cross section.
  • the scanning extensions can of course also have another curved shape, for example the shape of an elliptical section.
  • the different base angles or radii of curvature define the variations of the cylinder lock coding available at this scanning position.
  • the scanning extensions are designed as elongated webs at the tip of the core pins and are aligned in the longitudinal direction of the key channel essentially parallel to a central longitudinal plane of the key channel. This allows coding in the form of cut millings on the surface of a key to be interrogated.
  • At least two core pins have scanning extensions that run essentially parallel to one another and have a different distance from the central longitudinal plane of the key channel. This allows the number of variations of the lock to be increased further, since not only can different depths of cut milling be scanned, but also different normal distances from the central longitudinal plane are possible.
  • the scanning extensions are designed to scan cuts on the front face of a flat key and that spring-loaded scanning pins with scanning cams projecting into the key channel are provided on at least one side of the keyway, which are designed to scan further codes on the side surfaces of the flat key, wherein the distance of the scanning cams from the central longitudinal plane of the key channel is greater than the distance of the scanning extensions from the central longitudinal plane.
  • different types of core pins are provided that scan codes on the front faces and on the side faces of the key. This results in a particularly high number of variations in the possible codes.
  • the scanning extensions are arranged at different normal distances from the central longitudinal plane of the key channel.
  • the scanning extensions have different widths, i.e. different extensions normal to the central longitudinal plane of the key channel.
  • key-lock systems can be provided in which existing locks can be locked using a group of keys according to the invention.
  • Existing cylinder locks for example, have sensing extensions that protrude into the key channel as isosceles triangles or trapezoids with a base angle of 30°. These sensing extensions can be locked using appropriately designed, conical codings on the key with a base angle of 30°.
  • keys with codings that have a larger base angle, for example 40° also lock:
  • the edges of the sensing extensions remain attached to the edge of the coding on the surface of the key, while the tip of the sensing extensions does not touch the key.
  • three different base angles of 20°, 30° and 45° can be provided, whereby keys with a 45° code lock cylinder locks with 20°, 30° and 45° codes, while keys with a 30° code lock cylinder locks with 20° and 30° codes, and keys with a 20° code only lock cylinder locks with 20° codes.
  • This principle allows the keys according to the invention to be used to build hierarchies on existing locking systems, so that, for example, the new keys lock all old cylinder locks, but only selected new cylinder locks.
  • Fig.1 shows a first embodiment of a cylinder lock with an inserted flat key 14 (not part of the invention) in cross section.
  • the cylinder lock comprises a housing 1 and a cylinder core 3 rotatably mounted therein with a key channel 4.
  • the cylinder core 3 can be brought into a release position for operating the lock in a basically known manner by inserting an authorized flat key 14.
  • Spring-loaded housing pins 2 are provided in the housing 1 at the scanning positions A, B, C, D and E, which are connected in a manner also known in principle to Core pins 5 in the cylinder core 3 interact.
  • the flat key 14 is authorized to lock the lock, so that the core pins 5 and the housing pins 2 are displaced by codings on the end faces of the flat key 14 in such a way that a division plane 15 is formed and the cylinder core 3 can be rotated in the housing 1.
  • the core pins 5 protrude into the key channel 4 and have scanning extensions 6 at their ends protruding into the key channel 4 for querying codings of the flat key 14.
  • the scanning extensions 6 taper in the direction of the key channel 4.
  • the core pins 5 are cylindrical and the scanning extensions 6 have a conical pyramid-shaped taper, with the tip of the pyramid protruding into the key channel 4.
