    Key and cylinder lock
    The invention relates to a key and a cylinder lock for such a key. 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 projecting into the key channel, the core pins having scanning extensions at their ends projecting into the key channel for querying codes of the key.
    Such cylinder locks are known. In particular, it is known to provide different core pins and to arrange them in such a way that, on the one hand, core pins for querying codes on the end face of a flat key and, on the other hand, core pins for querying codes on the side face of such a key are provided. The codes on the key are regularly formed by the depth of the incisions. For example, AT 506 955 B1 shows a cylinder lock of this type and a flat key designed for this purpose with incised milling both on the end face and on the side surface of the key, and correspondingly designed core pins.
    A problem with such keys and cylinder locks is that not only the codes on the side surface of the key, but also the codes on the front surface of the key, can be read out relatively easily. In the case of the known keys, the codings are usually formed by incision milling, the depth of which, in terms of production technology, is directly proportional to the recess formed on the surface of the key. The recess formed on the surface can, however, be measured easily, for example by high-resolution photography, so that the depth of the incision milling and thus the coding of the key can be determined quickly.

    The object of the present invention consists in particular in solving these and other problems of conventional keys and cylinder locks and in realizing a key and a cylinder lock which on the one hand offers codings with sufficient variation possibilities and on the other hand makes fast copying by photographing the codings difficult.
    This object is achieved according to the invention by a key according to claim 1 and a cylinder lock according to claim 8.
    A key according to the invention has codings of different depths, which taper from a surface of the key in the direction of a longitudinal axis of the key. In this context, tapering means that the cross-section of the coding, which is implemented, for example, as a bore or incision milling, is reduced in the direction of the longitudinal axis of the key, that is to say normally to the longitudinal extent of the key. In this context, the longitudinal axis of the key is that axis which, in the case of a key inserted into a cylinder lock, runs parallel to the key channel of the cylinder lock. The surface mentioned can be an end surface, a side surface or any other surface of the key, for example also a groove base surface formed by a groove.
    According to the invention, at least two codings are provided, the extent of which on the surface of the key is essentially the same and which differ in depth and in the increase in their taper in the direction of the longitudinal axis of the key. It is thereby achieved that the key interacts with any core pins of the associated cylinder lock, but it is not possible to infer their pitch and depth from the extent of the coding on the surface of the key. The codings can be designed, for example, as bores, so that the extent on the surface is essentially circular, or else as incision milling, 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.

    According to the invention, it can be provided that the key is designed as a flat key, the codes being provided on at least one end face of the flat key. According to the invention, it can also be provided that the key is designed as a flat key, the codes being provided on at least one side surface of the flat key. Combinations thereof are also provided according to the invention, so that codes according to the invention are provided both on the end face and on the side surface of the key.
    Said surface of the key, in particular an end face, a side surface or the groove base surface of a groove of the key, can be flat, curved, curved, convex, concave or in any shape. The surfaces can be arranged at right angles, but it can also be provided that the surfaces enclose any angle.
    According to the invention it can be provided that the codings on the surface of the key are connected by a groove running parallel to the longitudinal axis of the key without forming edges. This allows the slope and depth of the codes to be effectively covered, so that the depth and slope of the codes cannot be inferred from a view or photograph of the surface of the key. In the event that the codes are provided on an end face of a flat key, the groove also has the advantage that the incision millings in the groove are covered laterally by two ribs of key material, which further complicates the ability to reproduce the key.
    According to the invention, it can be provided that the codings are designed as essentially conical bores, the cross sections of which essentially form isosceles triangles, at least two conical bores being provided, the cross sections of which essentially define isosceles triangles with different base angles. For example, base angles of 45 °, 35 ° and 20 ° can be provided. Instead of isosceles triangles, the cross sections of the codes can also form essentially isosceles trapezoids.

    According to the invention, it can be provided that the codings are designed as elongated incision millings, the cross sections of which essentially form circular arc sections, at least two incision millings being provided, the cross sections of which essentially define circular arc sections with a different radius of curvature. Instead of the shape of a circular arc, the incision millings can of course also have another curved shape, for example the shape of an ellipse section.
    It can be provided according to the invention that the incision millings are arranged parallel to the longitudinal axis of the key, at least two incision millings being arranged at different normal distances from the longitudinal axis of the key. This results in another possibility for varying the coding. In addition, in order to increase the possible variations, it can also be provided that the incision millings have different widths, that is to say 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 coding of the key. However, the invention also extends to cylinder locks designed specifically for use with a key according to the invention.
    Such a cylinder lock according to the invention 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 carry scanning extensions at their ends projecting into the key channel for querying the codes of a key. According to the invention it is provided that the scanning processes taper in the direction of the key channel, at least two core pins being provided which have the same extent, in particular the same diameter, but whose scanning processes differ in the increase in their taper. In this context, tapering means that the cross section of the core pins in the direction of the key channel, that is to say normal to the orientation of the key channel, is reduced.

    EWA Sicherheitstechnologie GmbH, Wienerbergstrasse 59-65, 1120 WIEN (AT)
    It is thereby achieved that, when the surface of a key designed to lock this cylinder lock is viewed or photographed, the extent of the tapering of the scanning extensions cannot be determined from the extent of the coding of the key on the surface. The codes on the key have the same extent on the surface of the key, but differ in their depth and in the extent of their taper.
    As is known, the core pins can have a circular cross-section with an identical diameter. The scanning extensions of the core pins can, starting from the core pins, be designed in the shape of a cone pyramid. However, there are also embodiments of the invention with any shaped projection extensions, for example scanning extensions which protrude from the core pins in an elliptical or circular segment into the key channel.
    According to the invention, it can be provided that the cross section of the scanning extensions forms an essentially isosceles triangle, at least two core pins being provided, the scanning extensions of which, in cross section, define isosceles triangles with different base angles. For example, base angles of 45 °, 35 ° and 20 ° can be provided. Instead of an isosceles triangle, the cross section of the scanning processes can also form an essentially isosceles trapezoid.
    According to the invention, it can be provided that the cross section of the scanning extensions essentially forms a circular arc section, at least two core pins being provided, the scanning extensions of which have circular arc sections with different radii of curvature in cross section. Instead of the shape of an arc, the scanning processes can of course also have another curved shape, for example the shape of an ellipse section.
    The different base angles or radii of curvature define the variations in the coding of the cylinder lock available at this scanning position.

    According to the invention, it can be provided that 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. As a result, codes in the form of notches on the surface of a key can be queried.
    According to the invention, it can be provided that at least two core pins have scanning projections which run essentially parallel to one another and are at a different distance from the central longitudinal plane of the key channel. As a result, the number of variations in the lock can be increased further, since not only can incisions of different depths be queried, but also different normal distances to the central longitudinal plane are possible.
    According to the invention, it can in particular be provided that the scanning extensions are designed for scanning incision millings on the end face of a flat key, and on at least one side of the key channel there are resiliently pretensioned scanning pins with scanning cams projecting into the key channel, which are used for scanning further codes on the side surfaces of the flat key are executed, wherein the distance of the scanning cam from the central longitudinal plane of the key channel is greater than the distance of the scanning processes from the
    Central longitudinal plane. In this case, different types of core pins are provided, which query codes on the end faces and on the side faces of the key. This results in a particularly high number of variations in the possible codings.
    It can further be provided that the scanning extensions are arranged at different normal distances from the central longitudinal plane of the key channel. In addition, in order to increase the possible variations, it can also be provided that the scanning processes have different widths, that is to say different expansions normal to the central longitudinal plane of the key channel.

    A particular advantage of the keys according to the invention is described below. Since the codes of the keys on the key surface always have the same extent, key-lock systems can be provided in which existing locks can be locked by a group of keys according to the invention. Existing cylinder locks have, for example, scanning extensions which protrude into the key channel as isosceles triangles or trapezoids with a base angle of 30 °. These scanning projections can be blocked by conical coding on the key with a base angle of 30 °. However, since the extent of the coding on the surface of the key is always the same, keys with codes that have a larger base angle, for example 40 °, also lock: the edges of the scanning processes in this case remain on the edge of the coding on the surface of the key , while the tip of the scanning processes does not touch the key. Specifically, three different base angles 20 °, 30 °, 45 ° can be provided, with keys with 45 ° coding locking cylinder locks with 20 °, 30 ° and 45 ° coding, while keys with 30 ° coding locking cylinders with 20 ° and lock 30 ° coding, and keys with a 20 ° coding only lock the cylinder locks with 20 ° coding. This principle allows the inventive keys 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.
    Finally, the invention also relates to systems comprising one or more keys according to the invention and conventional and / or cylinder locks according to the invention.
    Further features according to the invention result from the claims, the description of the exemplary embodiments and the drawings.
    The invention is explained in more detail below on the basis of a few exemplary embodiments schematically illustrated in the figures.

In the specific exemplary embodiment, the core pins 5 are cylindrical, and the scanning extensions 6 have a conical pyramid-shaped taper, the tip of the pyramid protruding into the key channel 4. The top of the pyramid is slightly flattened in terms of production technology, resulting in a trapezoidal cross-section. However, the invention is not limited to this form. Core pins 5 with differently shaped scanning projections are provided: at positions A and D a pyramid shape with a higher slope is provided, at positions B and E a flatter pyramid shape, and at position C an even flatter pyramid shape. However, the diameter of the cylindrical core pins is always essentially identical.

Also shown is a central longitudinal plane 11 of the key channel 4, which runs in the middle of the key channel 4.

    In the specific exemplary embodiment, three differently designed core pins 5, 5 ″, 5 ″, each with different scanning extensions 6, 6 ″, 6 ″, are provided. However, it is also provided that core pins 5 have identical scanning extensions 6 and differ only in their length. The core pins 5 at positions A, B and C are of different lengths despite the same scanning extension 6 in order to be able to query corresponding codes on a key. The diameter of the core pins 5, 5 ″, 5 ″ is always identical, however, and the core pins 5, 5 ’, 5 ″ are always essentially cylindrical at their end facing away from the key channel 4.
    The three different scanning processes 6, 6 ', 6 "are shown enlarged in the detailed representations. The scanning processes 6, 6 ″, 6 “differ with the same diameter in the increase in their taper in the direction of the key channel 4, which is located in the illustration above. In the cross section shown, the scanning extensions 6, 6 ″, 6 ″ each form an isosceles triangle 7, 7 ″, 7 ″ with different base angles 8, 8 ″, 8 ″. In the specific exemplary embodiment, a base angle of approximately 45 ° is provided at the scanning positions A, B and C, a basic angle of approximately 35 ° at the scanning position E, and a basic angle of approximately 20 ° at the scanning position D. However, exemplary embodiments of the invention with other base angles are also provided.
