Definitions
- the invention relates to a locking system with lock cylinders and matching flat keys and a method for producing a lock cylinder or a matching key for such a locking system with a sinusoidal based profile variation.
- the invention describes a profile variation on the flat keys or the key channels of the associated lock cylinder of a hierarchically structured locking system, in particular general-master key or central key system, wherein the broad sides of the key shanks generated according to a lock system-specific coding profile specification, extending in the longitudinal direction of the key shank Variation and the Key channels of the lock cylinder to have corresponding varying ribs, wherein the individuality and in particular the Schröhierarchie specifying Coding profile specification by a plurality, the edge distances of vertices of the Vari istsnuten of a longitudinal edge of the Whyschaftbreitseite, in particular from the spine, or the vertexes of the variating ribs from the edge of a broadside of the keyway and the vertex depths of the V-grooves or the Vertex heights of the Varying Rip is fixed in a cross-sectional plane through the key shank or the key channel extending sine functions whose zero lines parallel to the key center plane or key channel center plane and transverse to the
- the AT 405 550 B describes a cylinder lock with a key channel, from whose opposite side walls varying ribs protrude into the keyway.
- the V-ribs of the two broad sides are offset relative to one another and have a peak height such that the keyway has a paracentric profile.
- the vertices of the varying ribs are equally spaced from each other.
- the DE 101 34 894 A1 describes a profile variation on flat keys or key channels, in which the course of the bottom surfaces of Variationnuten and the faces of V-ribs along a sinusoidal function.
- the DE 10 2006 002 726 A1 describes a profile flat key with bulges in the key shank whose contour lines are approximated by a sine function.
- the DE 197 07 932 A1 describes the profile of a flat key, wherein the profile ribs have a parabolic cross-sectional contour and lying between the profile ribs of the key shank Variation grooves a V-shaped Have cross-sectional profile.
- the DE 103 06 371 A1 describes a profile variation for the production of locking systems, wherein rectilinear groove walls intersect at right angles.
- the key profiles described in the two last-mentioned documents lead to slim, from the side walls of the key channel outgoing Variation ribs. Especially in the head area, the flanks of these ribs can have a steep slope. This leads to a reduced stability, so that the V-ribs in the region of the key insertion opening of the key channel can bend when inserting a key.
- the invention has for its object to provide a more robust design rule for designing a variety of locking systems with hierarchical structure.
- the varying ribs have a cross section defined by the tip region of the sinusoids.
- the ribs thus have a cross-sectional area that is bordered by the wave crest of a sinusoid.
- the peak area of a sinusoidal amplitude can be approximated by a parabolic contour line.
- the cross-sectional areas of the ribs emanating from the side walls of the keyway have the cross-sectional area of about a parabola.
- the flanks of the tread rib are at the steepest where the tread ribs are thickest.
- the edge strength is reduced sub-proportional to the rib height. This leads to improved rib stability.
- the use of multiple sine functions not only leads to an optimal arrangement of adjacent ribs to each other.
- the use of a first and a second sine function, which have the same zero line, also leads to an easy-to-manufacture coding profile.
- the sine functions having the same wavelength parameter and the zero line having a distance greater than half the material thickness of the key shank remote from the key midplane outside the cross section of the key shank, it is ensured that only the outermost tip region of a sine amplitude is shaping the va riation groove .
- all of the multiple sine functions have only two different amplitude parameters.
- the amplitude parameters preferably differ only by small amounts, which are larger, however, than the sampling tolerances of varying ribs and variation grooves.
- sine functions alternate with mutually different amplitude parameters, so that a slightly higher rib is adjacent to a slightly lower rib.
- the same also applies to the variation grooves corresponding to the variation ribs.
- Two, three, four, five or preferably six sine functions preferably have the same wavelength and have a common zero line.
- all sine functions, the sine functions defining the edge distance position and the vertex depth of the variation grooves of a broad side of the key shank or of the key fins of the key channel have the same wavelength and lie in the same zero line.
- phase parameter is preferably selected such that the sine functions lie equidistant in the broad side extension of the key shank or in the vertical extent of the side wall of the key channel next to each other.
- the key shank broad side is divided into several regions in the transverse direction to the longitudinal extent of the key shank or the keyway wall. Each of these areas forms a variation zone.
- the variation zones have a plurality of V-ribs or associated V-grooves.
- a sine function may be the generator of a variation rib or variation groove in the first variation zone and at the same time the generator of a variation rib or variation groove in the second variation zone.
- the varying zones are preferably spaced apart by a distance. They are spatially separated. The distance is greater than the phase difference or greater than twice the phase difference of two adjacent sine functions.
- a first variation zone and a second variation zone may be associated on a common broadside of the key or a common keyway wall, respectively.
- a third variation zone associated with the opposite key shank broadside or keychain wall, respectively.
- a plurality of sine functions extend parallel to each other in such a way that they respectively define a variation rib or variation groove in the first and in the second variation zone.
- a guide rib or a guide groove can be arranged in the intermediate region between the first variation zone and the second variation zone.
- the guide rib protrudes as well as the V-ribs from the side wall of the keyway.
- the key profiles each have on their two broad sides at least one guide groove, wherein the guide grooves or guide ribs are arranged so that they protrude in a common longitudinal sectional plane of the key shaft or the keyway.
- the smooth-walled curved course of the V-ribs is also advantageous in terms of production engineering if the cylinder core having the key channel has transverse bores in which complementary tumblers are mounted, for example balls or pins. Due to the smooth-walled, kink-free contour line of the V-ribs, significantly fewer burrs are formed when clearing the key-channel. This is also the case if the guide grooves have a parabolic cross-sectional profile and in particular a cross-sectional profile generated by a sine function. The sine function in this regard may be in a different zero line than the sine functions defining the variation grooves or variation fins.
- the first variation zone can be used to distinguish locking systems from one another.
- a variation groove may indicate that the locking system is a general master key system and that the location of another variation groove in the first variation zone indicates that it is a central key system.
- the second variation zone may be used in an analogous manner to distinguish lock groups.
- Each of a plurality of lock groups has a specific variation groove that exists only on a key of the associated lock group.
- the key channels have corresponding V-ribs.
- the third variation zone can be used to vary the keys of a locking group.
- This third variation zone also has variation grooves / ribs whose position and their peak depth are defined by the previously described sine functions. With the invention, an optimal use of the limited variation spectrum is possible.

They correspond to the by the design rule of the two opposite walls of the keyway 8 projecting into the keyway varying ribs.
- a key can only be inserted into a key channel if the key, at least for each of the profiling ribs 11 to 19 or 32 to 36, has an associated variation groove 11 to 19; 32 to 36.
- a key can not be inserted into the lock cylinder, if the keyway at least one variation rib 11 to 19; 32 to 36, to which the key shank has no corresponding variation groove 11 to 19 or 32 to 36, so that the key tip is mechanically prevented from being inserted into the key channel with the presence of the variation rib.
- An additional variation groove 31 may be provided.
- the key shank 1 has a longitudinal direction extending from the tip of the key to the key of the key. In the direction of the longitudinal direction the key can be inserted into the keyway 8 of a cylinder core 9 of a lock cylinder.

- the coding grooves and the coding ribs which correspond to each other are designated by the same reference numerals.
- a coding rib, which is designated by a specific reference number, must be able to engage in a coding groove, which is designated by the same reference number, so that the key can be inserted into the associated lock cylinder.

- the amplitude parameters A 1 to A 7 may be the same. You can also differ.
- odd sine functions have the amplitude value C 1 and straight sine functions the amplitude value C 2 .
- the amplitude values C 1 , C 2 can differ only slightly. The difference essentially only needs to be slightly larger than the sampling tolerance of the key profile.
- Sinusoids of the sine functions are thus offset by a common multiple in the x-direction, so that adjacent peaks / peaks of the sine functions are equally spaced.

Die Sinusfunktionen besitzen denselben Wellenlängenparameter.The invention describes a profile variation on the flat keys or the key channels of the associated lock cylinder of a hierarchically structured locking system, in particular general-master key or central key system, wherein the broad sides of the key shanks generated according to a lock system-specific coding profile specification, extending in the longitudinal direction of the key shank Variation and the Key channels of the lock cylinder to have corresponding varying ribs, wherein the individuality and in particular the Schließhierarchie specifying Coding profile specification by a plurality, the edge distances of vertices of the Variierungsnuten of a longitudinal edge of the Schlüsselschaftbreitseite, in particular from the spine, or the vertexes of the variating ribs from the edge of a broadside of the keyway and the vertex depths of the V-grooves or the Vertex heights of the Varying Rip is fixed in a cross-sectional plane through the key shank or the key channel extending sine functions whose zero lines parallel to the key center plane or key channel center plane and transverse to the longitudinal direction of the key shank or the key channel, and whose defined by an amplitude parameter, a wavelength parameter and a phase curve, the position the vertex of the V-grooves respectively Describes varying ribs, wherein the varying ribs have a defined by the region of the peaks of the curve, wherein all the position of the vertices of a broadside defining sinusoidal functions have the same zero line whose distance from the key shank center plane or the keyway center plane is greater than half the material thickness of the key shank, so that the zero line is outside the cross-sectional area the key shank or the cross-sectional area of the key channel is located. The sine functions have the same wavelength parameter.

Die in den beiden zuletzt genannten Druckschriften beschriebenen Schlüsselprofile führen zu schlanken, von den Seitenwänden des Schlüsselkanals ausgehenden Variierungsrippen. Insbesondere im Kopfbereich können die Flanken dieser Rippen eine hohe Steilheit aufweisen. Dies führt zu einer verminderten Stabilität, so dass sich die Variierungsrippen im Bereich der Schlüsseleinstecköffnung des Schlüsselkanals beim Einschub eines Schlüssels verbiegen können.The key profiles described in the two last-mentioned documents lead to slim, from the side walls of the key channel outgoing Variation ribs. Especially in the head area, the flanks of these ribs can have a steep slope. This leads to a reduced stability, so that the V-ribs in the region of the key insertion opening of the key channel can bend when inserting a key.
Darüber hinaus besteht das Bedürfnis, das zur Verfügung stehende mechanische Permutationsspektrum optimal nutzen zu können.In addition, there is a need to optimally use the available mechanical permutation spectrum.
Der Erfindung liegt die Aufgabe zugrunde, eine zur Gestaltung einer Vielzahl von Schließanlagen mit hierarchischem Aufbau robustere Gestaltungsregel anzugeben.The invention has for its object to provide a more robust design rule for designing a variety of locking systems with hierarchical structure.
Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung. Es wird vorgeschlagen, dass die Variierungsrippen einen durch den Spitzenbereich der Sinusamplituden definierten Querschnitt aufweisen. Die Rippen haben somit eine Querschnittsfläche, die von dem Wellenberg einer Sinuskurve eingefasst ist. Der Spitzenbereich einer Sinusamplitude kann durch eine Parabelkonturlinie approximiert werden. Demzufolge besitzen die Querschnittsflächen der von den Seitenwänden des Schlüsselkanals ausgehenden Rippen die Querschnittsfläche etwa einer Parabel. Die Flanken der Profilrippe sind dort am steilsten, wo die Profilrippen am dicksten sind. Die Flankenstärke vermindert sich sub-proportional zur Rippenhöhe. Dies führt zu einer verbesserten Rippenstabilität. Die Verwendung mehrerer Sinusfunktionen führt nicht nur zu einer optimalen Anordnung benachbarter Rippen zueinander. Die Verwendung einer ersten und einer zweiten Sinusfunktion, die dieselbe Nulllinie aufweisen, führt darüber hinaus auch zu einem einfach zu fertigenden Codierungsprofil. Indem die Sinusfunktionen denselben Wellenlängenparameter aufweisen und die Nulllinie mit einem Abstand der größer ist als die halbe Materialstärke des Schlüsselschaftes entfernt von der Schlüsselmittelebene außerhalb des Querschnitts des Schlüsselschaftes liegt, ist sichergestellt, dass nur der äußerste Spitzenbereich einer Sinusamplitude formgebend für die Variierungsnut bzw. Variierungsrippe ist. Bevorzugt besitzen sämtliche der mehreren Sinusfunktionen nur zwei voneinander verschiedene Amplitudenparameter. Die Amplitudenparameter unterscheiden sich bevorzugt nur um geringe Beträge, die jedoch größer sind, als die Abtasttoleranzen von Variierungsrippen und Variierungsnuten. In einer bevorzugten Ausgestaltung wechseln sich Sinusfunktionen mit voneinander verschiedenen Amplitudenparametern ab, so dass eine geringfügig höhere Rippe einer geringfügig niedrigeren Rippe benachbart ist. Selbiges gilt auch für die zu den Variierungsrippen korrespondierenden Variierungsnuten. Zwei, drei, vier, fünf oder bevorzugt sechs Sinusfunktionen haben bevorzugt dieselbe Wellenlänge und haben eine gemeinsame Nulllinie. Vorzugsweise haben alle Sinusfunktionen, die die Randabstandslage und die Scheiteltiefe der Variierungsnuten einer Breitseite des Schlüsselschaftes oder der Variierungsrippen des Schlüsselkanals definierende Sinusfunktionen dieselbe Wellenlänge und liegen in derselben Nulllinie. Sie unterscheiden sich nur geringfügig durch einen Amplitudenparameter und durch einen Phasenparameter, wobei der Phasenparameter bevorzugt so gewählt ist, dass die Sinusfunktionen äquidistant in der Breitseitenerstreckung des Schlüsselschaftes bzw. in Höhenerstreckung der Seitenwand des Schlüsselkanals nebeneinander liegen.The object is achieved by the invention specified in the claims. It is proposed that the varying ribs have a cross section defined by the tip region of the sinusoids. The ribs thus have a cross-sectional area that is bordered by the wave crest of a sinusoid. The peak area of a sinusoidal amplitude can be approximated by a parabolic contour line. As a result, the cross-sectional areas of the ribs emanating from the side walls of the keyway have the cross-sectional area of about a parabola. The flanks of the tread rib are at the steepest where the tread ribs are thickest. The edge strength is reduced sub-proportional to the rib height. This leads to improved rib stability. The use of multiple sine functions not only leads to an optimal arrangement of adjacent ribs to each other. The use of a first and a second sine function, which have the same zero line, also leads to an easy-to-manufacture coding profile. By having the sine functions having the same wavelength parameter and the zero line having a distance greater than half the material thickness of the key shank remote from the key midplane outside the cross section of the key shank, it is ensured that only the outermost tip region of a sine amplitude is shaping the va riation groove , Preferably, all of the multiple sine functions have only two different amplitude parameters. The amplitude parameters preferably differ only by small amounts, which are larger, however, than the sampling tolerances of varying ribs and variation grooves. In a preferred embodiment, sine functions alternate with mutually different amplitude parameters, so that a slightly higher rib is adjacent to a slightly lower rib. The same also applies to the variation grooves corresponding to the variation ribs. Two, three, four, five or preferably six sine functions preferably have the same wavelength and have a common zero line. Preferably, all sine functions, the sine functions defining the edge distance position and the vertex depth of the variation grooves of a broad side of the key shank or of the key fins of the key channel have the same wavelength and lie in the same zero line. They differ only slightly by an amplitude parameter and by a phase parameter, wherein the phase parameter is preferably selected such that the sine functions lie equidistant in the broad side extension of the key shank or in the vertical extent of the side wall of the key channel next to each other.
In einer Weiterbildung der Erfindung ist vorgesehen, dass sich die Schlüsselschaftbreitseite in Querrichtung zur Längserstreckung des Schlüsselschaftes bzw. die Schlüsselkanalwandung in mehrere Bereiche unterteilt. Jeder dieser Bereiche bildet eine Variierungszone aus. Die Variierungszonen besitzen mehrere Variierungsrippen bzw. zugeordnete Variierungsnuten. Eine Sinusfunktion kann dabei die Erzeugende einer Variierungsrippe beziehungsweise Variierungsnut in der ersten Variierungszone und gleichzeitig die Erzeugende einer Variierungsrippe beziehungsweise Variierungsnut in der zweiten Variierungszone sein. Die Variierungszonen sind bevorzugt durch einen Abstand voneinander beabstandet. Sie sind räumlich voneinander getrennt. Der Abstand ist größer als der Phasenunterschied beziehungsweise größer als das Zweifache des Phasenunterschiedes zweier benachbarter Sinusfunktionen. Eine erste Variierungszone und eine zweite Variierungszone können auf einer gemeinsamen Breitseite des Schlüssels beziehungsweise einer gemeinsamen Schlüsselkanalwand zugeordnet sein. Es kann eine dritte Variierungszone vorgesehen sein, die der gegenüberliegenden Schlüsselschaft-Breitseite beziehungsweise Schlüsselkanalwand zugeordnet ist. Bevorzugt verlaufen mehrere Sinusfunktionen derart parallel zueinander, dass sie jeweils eine Variierungsrippe bzw. Variierungsnut in der ersten und in der zweiten Variierungszone definieren. Im Zwischenbereich zwischen der ersten Variierungszone und der zweiten Variierungszone kann eine Führungsrippe bzw. eine Führungsnut angeordnet sein. Die Führungsrippe ragt ebenso wie die Variierungsrippen von der Seitenwandung des Schlüsselkanals ab. Die Schlüsselprofile besitzen auf ihren beiden Breitseiten jeweils mindestens eine Führungsnut, wobei die Führungsnuten beziehungsweise Führungsrippen so angeordnet sind, dass sie in einer gemeinsamen Längsschnittebene vom Schlüsselschaft oder vom Schlüsselkanal hineinragen. Sie sind so angeordnet, dass sich ein parazentrisches Schlüsselprofil bzw. ein parazentrisches Schlüsselkanalprofil ausbildet. Der glattwandig gekrümmte Verlauf der Variierungsrippen ist fertigungstechnisch auch dann von Vorteil, wenn der den Schlüsselkanal aufweisende Zylinderkern Querbohrungen aufweist, in denen Ergänzungszuhaltungen gelagert sind, bspw. Kugeln oder Stifte. Zufolge der glattwandigen, knickstellenfreien Konturlinie der Variierungsrippen bilden sich beim Räumen des Schlüsselkanals erheblich weniger Grate. Dies ist auch dann gegeben, wenn die Führungsnuten ein parabolisches Querschnittsprofil und insbesondere ein von einer Sinusfunktion erzeugtes Querschnittsprofil aufweisen. Die diesbezügliche Sinusfunktion kann in einer anderen Nulllinie liegen als die die Variierungsnuten bzw. Variierungsrippen definierenden Sinusfunktionen. Es ist ferner von Vorteil, wenn die beiden voneinander verschiedenen Variierungszonen bei der Erstellung mehrerer Schließanlagen verschiedene Codierfunktionen übernehmen, so kann die erste Variierungszone verwendet werden, um Schließanlagen voneinander zu unterscheiden. Beispielsweise kann eine Variierungsnut kennzeichnen, dass es sich bei der Schließanlage um eine Generalhauptschlüsselanlage handelt und die Lage einer anderen Variierungsnut in der ersten Variierungszone kennzeichnen, dass es sich um eine Zentralschlüsselanlage handelt. Die zweite Variierungszone kann in einer analogen Weise dazu verwendet werden, um Schließgruppen voneinander zu unterscheiden. Jede einer Vielzahl von Schließgruppen besitzt eine spezifische Variierungsnut, die nur bei einem Schlüssel der zugehörigen Schließgruppe vorhanden ist. Die Schlüsselkanäle besitzen diesbezügliche Variierungsrippen. Die dritte Variierungszone kann dazu verwendet werden, die Schlüssel einer Schließgruppe zu variieren. Auch diese dritte Variierungszone besitzt Variierungsnuten/ -rippen, deren Lage und deren Scheiteltiefe von den zuvor beschriebenen Sinusfunktionen definiert werden. Mit der Erfindung ist eine optimale Nutzung des beschränkten Variierungsspektrums möglich.In a development of the invention, it is provided that the key shank broad side is divided into several regions in the transverse direction to the longitudinal extent of the key shank or the keyway wall. Each of these areas forms a variation zone. The variation zones have a plurality of V-ribs or associated V-grooves. A sine function may be the generator of a variation rib or variation groove in the first variation zone and at the same time the generator of a variation rib or variation groove in the second variation zone. The varying zones are preferably spaced apart by a distance. They are spatially separated. The distance is greater than the phase difference or greater than twice the phase difference of two adjacent sine functions. A first variation zone and a second variation zone may be associated on a common broadside of the key or a common keyway wall, respectively. There may be provided a third variation zone associated with the opposite key shank broadside or keychain wall, respectively. Preferably, a plurality of sine functions extend parallel to each other in such a way that they respectively define a variation rib or variation groove in the first and in the second variation zone. In the intermediate region between the first variation zone and the second variation zone, a guide rib or a guide groove can be arranged. The guide rib protrudes as well as the V-ribs from the side wall of the keyway. The key profiles each have on their two broad sides at least one guide groove, wherein the guide grooves or guide ribs are arranged so that they protrude in a common longitudinal sectional plane of the key shaft or the keyway. They are arranged so that a paracentric key profile or a paracentric key channel profile is formed. The smooth-walled curved course of the V-ribs is also advantageous in terms of production engineering if the cylinder core having the key channel has transverse bores in which complementary tumblers are mounted, for example balls or pins. Due to the smooth-walled, kink-free contour line of the V-ribs, significantly fewer burrs are formed when clearing the key-channel. This is also the case if the guide grooves have a parabolic cross-sectional profile and in particular a cross-sectional profile generated by a sine function. The sine function in this regard may be in a different zero line than the sine functions defining the variation grooves or variation fins. It is also advantageous if the two different zones of variation assume different coding functions when creating several locking systems, so the first variation zone can be used to distinguish locking systems from one another. For example, a variation groove may indicate that the locking system is a general master key system and that the location of another variation groove in the first variation zone indicates that it is a central key system. The second variation zone may be used in an analogous manner to distinguish lock groups. Each of a plurality of lock groups has a specific variation groove that exists only on a key of the associated lock group. The key channels have corresponding V-ribs. The third variation zone can be used to vary the keys of a locking group. This third variation zone also has variation grooves / ribs whose position and their peak depth are defined by the previously described sine functions. With the invention, an optimal use of the limited variation spectrum is possible.
Die Erfindung betrifft darüber hinaus eine Schließanlage, wobei die Lage und die Scheiteltiefe der Variierungsnuten oder Variierungsrippen ausschließlich durch Sinusfunktionen definiert ist, die denselben Wellenlängenparameter aufweisen und deren Nulllinien denselben Abstand von der Schlüsselmittenebene oder Schlüsselkanalmittenebene besitzen.

Die
Der Schlüsselschaft 1 besitzt eine Längsrichtung, die sich von der Spitze des Schlüssels zur Reide des Schlüssels erstreckt. In Richtung der Längsrichtung kann der Schlüssel in den Schlüsselkanal 8 eines Zylinderkerns 9 eines Schließzylinders eingesteckt werden. Auf seinen voneinander wegweisenden Breitseiten 2, 3 besitzt der Schlüsselschaft 1 die Variierungsnuten. Die Schlüsselbreitseite 2 kann die Variierungsnut 11, 12, 13, 14, 15, 16, 17, 18, 19 aufweisen. Die gegenüberliegende Breitseite 3 die Variierungsnuten 31, 32, 33, 34, 35, 36. Es ist vorgesehen, dass durch das Nichtvorhandensein einer oder mehrerer Variierungsnuten eine Codierung des Schlüssels erfolgt. Indem eine oder mehrere der Variierungsnuten an einem Schlüssel einer Schließanlage nicht vorhanden sind, wird verhindert, dass ein derartig codierter Schlüssel in einen Schließzylinder eingesteckt werden kann, bei dem von der Seitenwand des Schlüsselkanals 8 eine Codierungsrippe abragt, die an der Stelle der nicht vorhandenen Codierungsnut angeordnet ist.The
In den Figuren sind die Codierungsnuten und die Codierungsrippen, die zueinander korrespondieren mit denselben Bezugsziffern bezeichnet. Eine Codierungsrippe, die mit einer bestimmten Bezugsziffer bezeichnet ist, muss in eine Codierungsnut eingreifen können, die mit derselben Bezugsziffer bezeichnet ist, damit der Schlüssel in den zugehörigen Schließzylinder eingesteckt werden kann. Mit einer geeigneten Anordnung von Variierungsrippen 11 bis 19 beziehungsweise 31 bis 36 lässt sich somit eine abgeschlossene Menge von Schließzylindern derart codieren, dass in den Schlüsselkanal 8 nur solche Schlüssel eingeschoben werden können, bei denen die zugehörige Variierungsnut vorhanden ist.In the figures, the coding grooves and the coding ribs which correspond to each other are designated by the same reference numerals. A coding rib, which is designated by a specific reference number, must be able to engage in a coding groove, which is designated by the same reference number, so that the key can be inserted into the associated lock cylinder. With a suitable arrangement of V-
Die Erstellung eines Schließplanes einer Schließanlage erfolgt mit der erfindungsgemäßen Codierungsprofilvorgabe, die eine Mehrzahl von Sinuskurven verwendet, um die Lage und die Scheiteltiefe der Variierungsnuten 11 bis 19 beziehungsweise 31 bis 36 zu definieren. Die Lage einer Variierungsnut 11 bis 19 beziehungsweise 31 bis 36 ist durch ihren Abstand in Richtung x von der Randkante 2' beziehungsweise 3' der Breitseite 2, 3 oder durch eine Rückenebene R definiert. Die Randkante 2', 3' kann beispielsweise durch eine Schlüsselrückenebene R definiert sein. Die Sinusfunktionen erstrecken sich entlang einer Nulllinie 20, welche der x-Achse einer in einem X-Y-Koordinatensystem beschriebenen Sinuskurve entspricht. Die Spitzenabschnitte der Sinuskurve haben einen parabelähnlichen Verlauf und bilden zumindest die Scheitelbereiche der Variierungsnuten beziehungsweise Variierungsrippen aus. Die Nulllinie ist um das Maß n von einer durch die Querschnittsmitte des Profilkerns verlaufende Mittenebene M beabstandet. Der in der
Die Breitseite 2 eines Schlüsselschaftes 1 kann insgesamt neun Variierungsnuten 11 bis 19 aufweisen, wobei die Variierungsnuten durch die Wellenberge von Sinusfunktionen 21 bis 26 definiert werden. Die Sinusfunktionen 21 bis 26 haben denselben Wellenlängenparameter L und unterscheiden sich nur durch ihre Amplitudenparameter A und durch ihren Phasenparameter P.The
Bei einer Profilvariation, bei der sieben Sinusfunktionen verwendet werden, werden die Sinusfunktionen mit folgenden Gleichungen definiert:
Die Amplitudenparameter A1 bis A7 können gleich sein. Sie können sich aber auch unterscheiden. Bevorzugt nehmen die Amplitudenparameter A1 bis A7 zwei verschiedene Werte an, wobei sich Amplitudenparameter ungleicher Werte abwechseln, wie es die nachfolgenden Gleichungen beschreiben:
Es ist ersichtlich, dass ungerade Sinusfunktionen den Amplitudenwert C1 und gerade Sinusfunktionen den Amplitudenwert C2 besitzen. Die Amplitudenwerte C1, C2 können sich lediglich geringfügig unterscheiden. Der Unterschied braucht im Wesentlichen nur geringfügig größer zu sein, als die Abtasttoleranz des Schlüsselprofils.It can be seen that odd sine functions have the amplitude value C 1 and straight sine functions the amplitude value C 2 . The amplitude values C 1 , C 2 can differ only slightly. The difference essentially only needs to be slightly larger than the sampling tolerance of the key profile.
Es ist ferner vorgesehen, dass sich die Phasenparameter benachbarter Sinusfunktionen um einen konstanten Wert unterscheiden. Dies lässt sich mit folgender Rekursionsfunktion darstellen:
Sinuskurven der Sinusfunktionen sind somit um ein gemeinsames Vielfaches in x-Richtung versetzt, so dass benachbarte Wellenberge/Spitzen der Sinusfunktionen gleich beabstandet sind.Sinusoids of the sine functions are thus offset by a common multiple in the x-direction, so that adjacent peaks / peaks of the sine functions are equally spaced.
Beim Ausführungsbeispiel der
Eine zweite Variierungszone mit Variierungsnuten 14, 15, 16, 17, 18, 19 wird von den in x-Richtung gleich beabstandeten Sinusfunktionen 21, 22, 23, 24, 25, 26 definiert. Es ist ersichtlich, dass die Sinusfunktion 23 sowohl die Variierungsnut 11 als auch die Variierungsnut 16, die Sinusfunktion 24 sowohl die Variierungsnut 12 als auch die Variierungsnut 17 und die Sinusfunktion 25 sowohl die Variierungsnut 13 als auch die Variierungsnut 18 definiert. Lediglich die Variierungsnuten 19, 14 und 15 werden von Sinusfunktionen 21, 22 und 26 definiert, die ansonsten keine weiteren Variierungsnuten definieren.A second variation zone with
Nebeneinander liegende Sinusfunktionen 21, 22, 23, 24, 25, 26 besitzen Scheitelpunkte 21', 22', 23', 24', 25', 26', die eine unterschiedliche Scheitelhöhe besitzen. Die Scheitelhöhe variiert um das Abstandsmaß d und ist durch den Amplitudenparameter A1 bis A7 definiert. Durch die Scheitelhöhe beziehungsweise den Amplitudenparameter ist die Scheiteltiefe der Variierungsnut 11 bis 19 definiert. Der Phasenparameter P1 bis P7 definiert die Randabstandslage der Variierungsnut 11 bis 19.Adjacent sine functions 21, 22, 23, 24, 25, 26 have vertices 21 ', 22', 23 ', 24', 25 ', 26', which have a different peak height. The peak height varies by the distance d and is defined by the amplitude parameter A 1 to A 7 . The peak height of the
Analoges gilt für die Lage der Variierungsrippen 11 bis 19, die von der Seitenwand des Schlüsselkanals 8 in den Schlüsselkanal 8 hineinragen.The same applies to the position of the varying
Die gegenüberliegende Breitseite 3 besitzt weitere Variierungszonen, die von drei Sinusfunktionen 27, 28, 29 definiert sind. Diese Sinusfunktionen besitzen einen Nulllinie 20', die um dasselbe Maß n von der Schlüsselschaftmittenebene M beabstandet ist, wie die Nulllinie 20. Die Sinusfunktionen 27 bis 29 werden durch dieselbe in den Gleichungen 1 bis 9 angegebene Gesetzmäßigkeit definiert. Es bilden sich zumindest zwei weitere Variierungszonen aus. In einer Variierungszone verlaufen die Variierungsnuten 32, 33, 34. In einer anderen Variierungszone verlaufen die Variierungsnuten 35, 36.The opposite broad side 3 has further variation zones, which are defined by three sine functions 27, 28, 29. These sine functions have a zero line 20 'that is the same measure n from the key shank center plane M is spaced as the zero
Schließlich besitzt die Schlüsselbreitseite 3 noch die Variierungsnut 31. Auch hier ist vorgesehen, dass von einer Sinusfunktion auch mehrere Variierungsnuten 31 bis 36 definiert werden können.Finally, the key broadside 3 still has the variation groove 31. It is also provided here that a plurality of variation grooves 31 to 36 can also be defined by a sine function.
Das Vorhandensein einer der Variierungsnuten/ -rippen 11, 12, 13 der ersten Variierungszone kann als Kennzeichnung verwendet werden, dass es sich bei dem Schlüssel beziehungsweise Schließzylinder um ein Element einer General-Hauptschlüsselanlage handelt. Das Vorhandensein einer anderen Variierungsnut/ -rippe 11, 12, 13 der ersten Variierungszone kann verwendet werden, um einen Schlüssel oder einen Schließzylinder als Element einer Zentralschlüsselanlage zu kennzeichnen. Die Variierungsnuten/ -rippen 14 bis 19 der zweiten Variierungszone können zur Individualisierung der Schlüssel beziehungsweise Schließzylinder einer Schließanlage verwendet werden. Dasselbe gilt für die Variierungsnuten/ -rippen 31 bis 36 der weiteren Variierungszonen.The presence of one of the variation grooves /

Anders als bei dem zuvor erörterten Ausführungsbeispiel handelt es sich hier um ein Profil für einen Wendeflachschlüssel. Das Profil ist um eine Zentrumsachse des Profilkerns um 180° drehsymmetrisch. Auch hier werden die Lagen und die Tiefen der einzelnen Variierungsnuten 10 bis 19 beziehungsweise die Höhen der Variierungsrippen 10 bis 19 durch einen Satz von Sinuskurven definiert, die den obigen Gleichungen 1 bis 9 gehorchen. Es sind insgesamt sieben Sinuskurven 21 bis 27 vorgesehen, mit denen drei räumlich voneinander getrennte Variierungszonen bestimmt werden. Eine erste Variierungszone mit den Variierungsnuten 10, 11, 12, 13 wird von den Sinusfunktionen 24 bis 27 definiert. Weitere Sinusfunktionen 21, 22, 23, die mit den Sinusfunktionen 24 bis 27 einen Satz von in gleichen Schritten beabstandeten Sinusfunktionen ausbilden, definieren die Variierungsnuten 14 bis 16 der zweiten Variierungszone. Die Sinusfunktionen 22 bis 24 definieren darüber hinaus auch die Lage der Variierungsnuten 17 bis 19 der dritten Variierungszone. Die Sinusfunktion 24 definiert somit eine Variierungsnut 10 der ersten Variierungszone und eine Variierungsnut 19 der dritten Variierungszone.
