Definitions
- the invention relates to a key for a lock cylinder with a reed and a shaft, with two broad sides of the shaft, with a key face and a key back for connecting the broad sides of the shaft, with profiles arranged in the broad sides and with profiles on the broad sides of the shaft, and with a key tip located at the free end of the shaft.
- the invention further relates to a locking cylinder for such a key with a core that can be moved in a housing, with a locking channel for receiving a shaft of a key, with locking elements that can be controlled by locking recesses in the key for selectively locking or releasing the movement of the core.
- a lock-key system has become known in which core pins scan the profile of the shaft.
- the profile has a groove that tapers from the key tip towards the reed.
- a core pin penetrates the groove and is pushed radially outwards by the increasing taper. When the core rotates, the core pin faces a movable housing pin.
- the WO 01/48341 A1 discloses a lock-key combination in which a lateral profiling of the key is queried.
- the profiling has straight grooves and webs.
- the disadvantage of the keys according to the state of the art is that they are limited to a few locking secrets. This means that the key can only be used to a limited extent in locking systems. Furthermore, that is the key The underlying locking secret is easy to read, so it can be copied very easily.
- the invention is based on the problem of designing a key of the type mentioned in such a way that it has a particularly high level of copy protection and enables a particularly large number of locking secrets. Furthermore, a locking cylinder should be created for such a key, which enables a particularly varied design of the locking secrets.
- profiling of the broad sides is designed differently, so that the profiling on one of the broad sides is designed parallel and has a wave-shaped groove on the other broad side.
- This design allows the key to be provided with different locking secrets on both broad sides and the key face.
- the key therefore has a particularly large number of locking secrets. It is not clear from the key which locking secrets are used in the locking cylinder provided for this purpose.
- the locking secrets on the two broadsides are designed differently. This means that the key offers a particularly high level of copy protection.
- the undercut could, for example, only be arranged in a groove wall. According to another advantageous development of the invention, it contributes to further increasing the copy protection of the key if the undercut of the wave-shaped groove is arranged in both groove walls.
- the undercuts in the groove walls are dovetail-shaped. This allows the Make undercuts in both groove walls using an appropriate milling cutter.
- the key enables use for a large number of locking secrets if the wave-shaped groove has a section with a large width and a section with a relatively small width.
- This design allows the wave-shaped groove to be scanned, for example, with differently preloaded control elements or with sliding blocks of different widths.
- contamination can be removed simply by using the key if the wave-shaped groove is guided past a stop designed to limit the insertion length of the shaft.
- a sliding block that corresponds to the wave-shaped groove slides along in the wave-shaped groove and transports possible contamination past the stop.
- the invention contributes to simplifying the removal of impurities if the wave-shaped groove is guided up to a circular recess that is open to the outside. Such a recess is particularly easy to produce.
- a sliding block guided transversely to the broad side of the shaft in the lock cylinder can be easily picked up by the wave-shaped groove if the wave-shaped groove has a funnel-shaped inlet at the key tip.
- the key can be equipped with a large number of locking secrets if the shaft has three rows of locking recesses, with a first row of locking recesses in the key chest, a second row of locking recesses from the wave-shaped groove and a third Row of closing recesses in which the parallel profiling Broadside is formed.
- the row of locking recesses can also consist of a single locking recess.
- the key is structurally particularly simple if the third row of the locking recess is arranged on a web.
- the web is preferably arranged offset from the wave-shaped groove on the other broad side.
- the second problem mentioned namely the creation of a locking cylinder with a particularly varied design of the locking secrets, is solved according to the invention in that a locking strip is guided in the core next to the locking channel in a displaceable manner relative to a locking recess in the housing, so that the position of the locking strip is one of the wave-shaped Groove of the key controllable control element between a locking position and a release position can be controlled.
- This design allows the lock cylinder to scan the key in completely different ways on three sides. This allows a particularly varied design of locking secrets to be achieved, making it very difficult to simply copy the key.
- the locking bar is designed as a locking element. To further increase the number of locking secrets, several guide recesses for locking strips can also be arranged in the core, particularly in locking systems.
- a sliding block connected to the control element and intended to penetrate into the wave-shaped groove of the key has a widening corresponding to the undercut of the wave-shaped groove. If there are several sliding blocks, one of the sliding blocks preferably has the widening and another does not. This contributes to further increasing the locking secrets.
- Figure 1 shows a lock cylinder 1 with a key 2 inserted therein.
- the lock cylinder 1 has a housing 3 with a core 4 rotatably mounted therein and a series of pin tumblers 5 for selectively locking or releasing the movement of the core 4 in the housing 3.
- the core 4 has a locking channel 6 for receiving a shaft 7 of the key 2 and is coupled to a locking bit 9 via a driver 8.
- the key 2 has a reed 10 connected to the shaft 7 and a stop 11 with which it is supported on an end face of the core 4.
- the shaft 7 has a straight key back 12 and a key face 13 with a first row of locking recesses 14 for controlling the pin tumblers 5.
- a profile 16 with a wave-shaped groove 17 is arranged on a broad side 15 of the shaft 7.
- the wave-shaped groove 17 is guided from a key tip 18 arranged at the free end of the shaft 7 to an open recess 19 arranged behind the stop 11.
- the wave-shaped groove 17 with a funnel-shaped inlet 20 has a wide section 21.
- One up to the Section 22 guided in the recess 19 is designed to be narrower than the wide section 21 at the key tip 18.
- Figure 2 shows a sectional view through the lock cylinder 1 with the key 2 along the lines II - II. It can be seen here that the shaft 7 also has a profile 24 with a protruding web 25 and longitudinal grooves 26 on a further broad side 23. This profiling 24 is designed parallel to the key back 12.
- the wavy groove 17 has an undercut 27 in both groove walls.
- a sliding block 28 with a widening corresponding to the undercut 27 penetrates into the wave-shaped groove 17.
- the sliding block 28 is connected to a control element 30 which is biased by a displaceable spring element 29.
- the control element 30 has a guide recess 31 for a closing strip 32 guided in the core 4.
- the closing strip 32 faces a locking recess 33 in the housing 3.
- the position of the control element 30, which is dependent on the wave-shaped groove 17, thus controls the position of the closing strip 32.
- a second row of closing recesses 35 is thus formed by the wave-shaped groove 17.
- Figure 3 shows a sectional view through the lock cylinder 1 with the key 2 Figure 2 along the line III - III that several control elements 30 are arranged on one broad side 15 and several pin tumblers 34 on the other broad side 23 of the key 2.
- key 2 has a high number of locking secrets.
- the closing strip 32 is biased by spring elements 37 in the direction of the locking recess 33 in the housing 3 and is pressed back into the core 4 when the control elements 30 are released when the core 4 rotates.
- FIG. 4 shows, enlarged for clarity, the shaft 7 of the key 2 in a view of the wavy groove 17.
- This wavy groove 17 is scanned by sliding blocks 28 connected to the control elements 30 and thus controls the position of the closing strip 30.
- Figure 5 shows the shaft 7 of the key 2 in a view of the parallel profile 24 with the third row of locking recesses 36.
- Parallel longitudinal grooves 26 and webs 25 extend over the entire broad side 23 of the shaft 7.
- Figure 6 shows the key 2 enlarged in a perspective view of the key tip 18.
- the section 21 of the wave-shaped groove 17 arranged on the key tip 18 has the undercut 27 on one groove wall 38, while the other groove wall 39 is perpendicular to the broad side 15 of the shaft 7 is arranged.
- both groove walls 38, 39 have the undercut 27.

Nachteilig bei den Schlüsseln nach dem Stand der Technik ist, dass er auf wenige Schließgeheimnisse beschränkt ist. Hierdurch ist der Schlüssel in Schließanlagen nur eingeschränkt einsetzbar. Weiterhin ist das dem Schlüssel zugrunde liegende Schließgeheimnis einfach ablesbar, so dass er sehr einfach kopiert werden kann.The disadvantage of the keys according to the state of the art is that they are limited to a few locking secrets. This means that the key can only be used to a limited extent in locking systems. Furthermore, that is the key The underlying locking secret is easy to read, so it can be copied very easily.
Der Erfindung liegt das Problem zugrunde, einen Schlüssel der eingangs genannten Art so zu gestalten, dass er einen besonders hohen Kopierschutz aufweist und eine besonders große Anzahl an Schließgeheimnissen ermöglicht. Weiterhin soll ein Schließzylinder für einen solchen Schlüssel geschaffen werden, mit dem eine besonders variantenreiche Gestaltung der Schließgeheimnisse ermöglicht wird.The invention is based on the problem of designing a key of the type mentioned in such a way that it has a particularly high level of copy protection and enables a particularly large number of locking secrets. Furthermore, a locking cylinder should be created for such a key, which enables a particularly varied design of the locking secrets.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass die Profilierungen der Breitseiten in ihrer Art unterschiedlich gestaltet sind, so dass die Profilierung an einer der Breitseiten parallel gestaltet ist und an der anderen Breitseite eine wellenförmig gestaltete Nut aufweist.This problem is solved according to the invention in that the profiling of the broad sides is designed differently, so that the profiling on one of the broad sides is designed parallel and has a wave-shaped groove on the other broad side.
Durch diese Gestaltung lässt sich der Schlüssel an den beiden Breitseiten und der Schlüsselbrust mit unterschiedlichen Schließgeheimnissen versehen. Der Schlüssel weist hierdurch eine besonders große Anzahl an Schließgeheimnissen auf. Welche Schließgeheimnisse in dem hierfür vorgesehenen Schließzylinder genutzt werden, ist an dem Schlüssel nicht ersichtlich. Zudem sind die Schließgeheimnisse auf den beiden Breitseiten unterschiedlich gestaltet. Hierdurch bietet der Schlüssel einen besonders hohen Kopierschutz.This design allows the key to be provided with different locking secrets on both broad sides and the key face. The key therefore has a particularly large number of locking secrets. It is not clear from the key which locking secrets are used in the locking cylinder provided for this purpose. In addition, the locking secrets on the two broadsides are designed differently. This means that the key offers a particularly high level of copy protection.
Zur Erhöhung des Kopierschutzes des Schlüssels trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn die wellenförmige Nut eine Hinterschneidung hat.According to another advantageous development of the invention, it contributes to increasing the copy protection of the key if the wave-shaped groove has an undercut.
Die Hinterschneidung könnte beispielsweise nur in einer Nutwand angeordnet sein. Zur weiteren Erhöhung des Kopierschutzes des Schlüssels trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn die Hinterschneidung der wellenförmigen Nut in beiden Nutwänden angeordnet ist. Im einfachsten Fall sind die Hinterschneidungen in den Nutwänden schwalbenschwanzförmig gestaltet. Hierdurch lassen sich die Hinterschneidungen in beiden Nutwänden mit einem entsprechenden Fräser fertigen.The undercut could, for example, only be arranged in a groove wall. According to another advantageous development of the invention, it contributes to further increasing the copy protection of the key if the undercut of the wave-shaped groove is arranged in both groove walls. In the simplest case, the undercuts in the groove walls are dovetail-shaped. This allows the Make undercuts in both groove walls using an appropriate milling cutter.
Der Schlüssel ermöglicht gemäß einer anderen vorteilhaften Weiterbildung der Erfindung den Einsatz für eine große Anzahl an Schließgeheimnissen, wenn die wellenförmige Nut einen Abschnitt mit einer großen Breite und einen Abschnitt mit einer im Verhältnis dazu kleinen Breite aufweist. Durch diese Gestaltung lässt sich die wellenförmige Nut beispielsweise mit unterschiedlich vorgespannten Steuerelementen oder mit unterschiedlich breiten Nutensteinen abtasten.According to another advantageous development of the invention, the key enables use for a large number of locking secrets if the wave-shaped groove has a section with a large width and a section with a relatively small width. This design allows the wave-shaped groove to be scanned, for example, with differently preloaded control elements or with sliding blocks of different widths.
Verunreinigungen lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach durch die Benutzung des Schlüssels abführen, wenn die wellenförmige Nut bis hinter einen zur Begrenzung der Einführlänge des Schaftes ausgebildeten Anschlag geführt ist. Bei der Benutzung des Schlüssels gleitet ein mit der wellenförmigen Nut korrespondierender Nutenstein in der wellenförmigen Nut entlang und fördert mögliche Verunreinigungen bis hinter den Anschlag.According to another advantageous development of the invention, contamination can be removed simply by using the key if the wave-shaped groove is guided past a stop designed to limit the insertion length of the shaft. When using the key, a sliding block that corresponds to the wave-shaped groove slides along in the wave-shaped groove and transports possible contamination past the stop.
Zur Vereinfachung der Abführung von Verunreinigungen trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn die wellenförmige Nut bis zu einer kreisförmigen, nach außen offenen Ausnehmung geführt ist. Eine solche Ausnehmung ist besonders einfach herstellbar.According to another advantageous development of the invention, it contributes to simplifying the removal of impurities if the wave-shaped groove is guided up to a circular recess that is open to the outside. Such a recess is particularly easy to produce.
Ein quer zur Breitseite des Schaftes im Schließzylinder geführter Nutenstein lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung von der wellenförmigen Nut einfach aufnehmen, wenn die wellenförmige Nut an der Schlüsselspitze einen trichterförmigen Einlauf hat.According to another advantageous development of the invention, a sliding block guided transversely to the broad side of the shaft in the lock cylinder can be easily picked up by the wave-shaped groove if the wave-shaped groove has a funnel-shaped inlet at the key tip.
Der Schlüssel lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung mit einer großen Anzahl an Schließgeheimnissen ausstatten, wenn der Schaft drei Reihen von Schließausnehmungen aufweist, wobei eine erste Reihe der Schließausnehmungen in der Schlüsselbrust, eine zweite Reihe der Schließausnehmungen von der wellenförmigen Nut und eine dritte Reihe der Schließausnehmungen in der die parallele Profilierung aufweisenden Breitseite gebildet ist. Im einfachsten Fall kann auch die Reihe der Schließausnehmungen aus einer einzigen Schließausnehmung bestehen.According to another advantageous development of the invention, the key can be equipped with a large number of locking secrets if the shaft has three rows of locking recesses, with a first row of locking recesses in the key chest, a second row of locking recesses from the wave-shaped groove and a third Row of closing recesses in which the parallel profiling Broadside is formed. In the simplest case, the row of locking recesses can also consist of a single locking recess.
Der Schlüssel gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn die dritte Reihe der Schließausnehmung auf einem Steg angeordnet ist. Vorzugsweise ist der Steg versetzt zu der wellenförmigen Nut auf der anderen Breitseite angeordnet.According to another advantageous development of the invention, the key is structurally particularly simple if the third row of the locking recess is arranged on a web. The web is preferably arranged offset from the wave-shaped groove on the other broad side.
Das zweitgenannte Problem, nämlich die Schaffung eines Schließzylinders mit einer besonders variantenreichen Gestaltung der Schließgeheimnisse, wird erfindungsgemäß dadurch gelöst, dass in dem Kern neben dem Schließkanal eine Schließleiste verschieblich gegenüber einer Sperrausnehmung im Gehäuse geführt ist, dass die Position der Schließleiste von einem von der wellenförmigen Nut des Schlüssels ansteuerbaren Steuerelement zwischen einer Verriegelungsstellung und einer Freigabestellung steuerbar ist.The second problem mentioned, namely the creation of a locking cylinder with a particularly varied design of the locking secrets, is solved according to the invention in that a locking strip is guided in the core next to the locking channel in a displaceable manner relative to a locking recess in the housing, so that the position of the locking strip is one of the wave-shaped Groove of the key controllable control element between a locking position and a release position can be controlled.
Durch diese Gestaltung ermöglicht der Schließzylinder ein völlig unterschiedliches Abtasten des Schlüssels an drei Seiten. Damit lässt sich eine besonders variantenreiche Gestaltung von Schließgeheimnissen erreichen, so dass ein einfaches Kopieren des Schlüssels nur sehr schwer möglich ist. Zudem ist die Sperrleiste als Sperrelement ausgebildet. Zur weiteren Erhöhung der Anzahl der Schließgeheimnisse können insbesondere in Schließanlagen auch mehrere Führungsausnehmungen für Schließleisten im Kern angeordnet sein.This design allows the lock cylinder to scan the key in completely different ways on three sides. This allows a particularly varied design of locking secrets to be achieved, making it very difficult to simply copy the key. In addition, the locking bar is designed as a locking element. To further increase the number of locking secrets, several guide recesses for locking strips can also be arranged in the core, particularly in locking systems.
Zur besonders genauen Führung des Steuerelementes durch den Schlüssel trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn ein mit dem Steuerelement verbundener, zum Eindringen in die wellenförmige Nut des Schlüssels vorgesehener Nutenstein eine der Hinterschneidung der wellenförmigen Nut entsprechende Verbreiterung hat. Bei mehreren Nutensteinen weist vorzugsweise einer der Nutensteine die Verbreiterung auf und ein anderer nicht. Dies trägt zur weiteren Erhöhung der Schließgeheimnisse bei.According to another advantageous development of the invention, it contributes to particularly precise guidance of the control element by the key if a sliding block connected to the control element and intended to penetrate into the wave-shaped groove of the key has a widening corresponding to the undercut of the wave-shaped groove. If there are several sliding blocks, one of the sliding blocks preferably has the widening and another does not. This contributes to further increasing the locking secrets.
