Description

Die Erfindung betrifft einen Schließzylinder mit einem Schlüssel gemäß Gattungsbegriff des Anspruchs 1.The invention relates to a lock cylinder with a key according to the preamble of claim 1.

Aus der DE 3832143 C2 ist ein Schließzylinder mit einem Schlüssel bekannt, bei dem die Kernstifte eine Flachrippe aufweisen. Seitlich der Flachrippe befinden sich Aussteuerungsschrägen, an denen eine Flanke eines Schlüssels angreifen kann. Der Schlüssel ist derart gestaltet, dass dieser zuerst an den Aussteuerungsschrägen und nach einem gewissen Verlagerungsweg erst an der Flanke des Zylinderstiftes angreift und diesen vollständig verlagert. Die Flachrippe des Kernstiftes wird in einer Einlaufnut des Schlüssels geführt. Es ist nur möglich, die Stiftzuhaltung in eine Freigabestellung zu verlagern, wenn man einen richtigen Schlüssel besitzt, der die Steuerzone aufweist, um an den Aussteuerungsschrägen anzugreifen. Sonst ist es nicht möglich, die Stiftzuhaltung in eine Freigabestellung zu verlagern. Die Stifte dürfen sich nicht drehen.From the DE 3832143 C2 a lock cylinder with a key is known in which the core pins have a flat rib. Side of the flat rib are control slopes, which can attack a flank of a key. The key is designed such that it first acts on the control slopes and after a certain displacement only on the flank of the cylinder pin and this completely shifted. The flat rib of the core pin is guided in an inlet groove of the key. It is only possible to relocate the pin tumbler to a release position if one has a proper key having the control zone to attack the ramps. Otherwise it is not possible to relocate the pin tumbler to a release position. The pins must not turn.

Aus der DE 102004003034 ist ein Schließzylinder mit einem Schlüssel beschrieben, dessen Kernstifte einen querschnittsreduzierten Zylinderabschnitt aufweisen. Dieser Zylinderabschnitt kann ein Entsperrelement in dem Schließzylinder fesseln. Ein derartiges Entsperrelement, das für die Perkussionsmethode benötigt wird, weist tiefere Einschnitte auf als es für das System vorgesehen ist. Durch die tieferen Einschnitte entstehen in dem Entsperrelement, im Bereich des höhenverminderten Abschnitts der Tiefrippe Löcher. In diese Löcher kann der Zylinderabschnitt des Kernstiftes eintreten und das Entsperrelement fesseln. Nun ist es nicht mehr möglich, das Entsperrelement weiter hineinzuschieben oder wieder herauszuziehen. Der Schließzylinder ist somit vor der Perkussionsmethode geschützt und kann nicht durch diese Methode geöffnet werden. Des Weiteren sind im Wesentlichen die Kernstifte sowie der Schlüssel wie in der zuvor erwähnten Druckschrift ausgestaltet.From the DE 102004003034 a lock cylinder is described with a key whose core pins have a cross-section reduced cylinder portion. This cylinder section can tie an unlocking element in the lock cylinder. Such an unlocking element, which is needed for the percussion method, has deeper cuts than provided for the system. Due to the deeper cuts arise in the unlocking, in the area of the reduced-height portion of the deep rib holes. In these holes, the cylinder portion of the core pin can enter and captivate the unlocking. Now it is no longer possible to push the unlocking further into or out again. The lock cylinder is thus protected from the percussion method and can not be opened by this method. Furthermore, essentially the Core pins and the key as configured in the aforementioned document.

Die US 5,438,857 beschreibt verschiedene Schlüsselprofile mit Nuten und Rippen, wobei die den Nuten benachbarten einschubseitigen Stirnflächen der Rippen angeschrägt sind, um die Zuhaltungsstifte beim Einschub des Schlüssels in den Schlüsselkanal des Schließzylinders anzuheben. Aus den randseitig von einer Fase umgebenden Stirnflächen der im Wesentlichen zylindrischen Zuhaltungsstifte ragen sockelartige Fortsätze. Eines der dort vorgeschlagenen Schlüsselprofile sieht ein in einer Nut eingebettete Hochrippe vor, die eine schräge Stirnfläche ausbildet, entlang welcher der Fortsatz des Zuhaltungsstiftes beim Einschub des Schlüssels entlang gleitet. Bei einem anderen Schlüsselprofil taucht der Fortsatz durch die Nut hindurch. Dort gleitet die den Rand der Stirnseite bildende Fase auf den Schrägflanken entlang.The US 5,438,857 describes various key profiles with grooves and ribs, wherein the slots adjacent to the insertion side end faces of the ribs are chamfered to lift the tumbler pins during insertion of the key in the keyway of the lock cylinder. From the edge side of a chamfer surrounding end faces of the substantially cylindrical tumbler pins project pedestal-like extensions. One of the key profiles proposed there provides a high rib embedded in a groove, which forms an oblique face along which the extension of the tumbler pin slides when the key is inserted. In another key profile, the extension dips through the groove. There, the chamfer forming the edge of the front side slides along the inclined edges.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Schließzylinder mit einem Schlüssel hertellungstechnisch zu vereinfachen.The invention has for its object to simplify hertellungstechnisch a generic lock cylinder with a key.

Gelöst wird die Aufgabe durch die im Anspruch 1 angegebene Erfindung.The problem is solved by the invention defined in claim 1.

Bevorzugt ist die Querschnittsform der Steuerflanken den Steuerzonen formangepasst. Die Steuerzonen gleiten im Wesentlichen in Linienanlage an den Steuerflanken ab. Diese weisen eine gerundete Gestalt auf. Die Spitze mindestens eines Kernstiftes bildet einen zylindrischen Fortsatz aus. Der Boden des Schlüsselkanals weist Vertiefungen auf zum Eintritt der Spitze oder des zylindrischen Fortsatzes des mindestens eines Kernstiftes. Der Grund des Kanals bildet eine Auflaufschräge für die Spitze des Kernstiftes aus. Diese tritt erst nach einer Anfangsverlagerung durch die Steuerflanken gegen die Auflaufschräge. Der Schlüssel ist als Wendeflachschlüssel ausgestaltet. Eine Vielzahl von in Einsteckrichtung des Schlüssels hintereinanderliegender Kernstifte sind in dem Schließzylinder angeordnet. Ein oder mehrere Kernstifte bilden an ihren Spitzen zylindrische Fortsätze aus. Die Auflaufschräge ist einer Tiefrippe sowie einer Hochrippe des Schlüssels zugeordnet. Die Auflaufschräge erstreckt sich über im Wesentlichen die gesamte Schlüsseldicke. Den Böden zweier eine Hochrippe flankierenden Nut sind die Steuerflanken zugeordnet. Diese können auch den schrägen Wandungen einer Tiefrippe zugeordnet sein. Die Steuerzonen und die Auflaufschrägen besitzen unterschiedliche Winkel zur Schlüsselkanalebene. Die axiale Länge der Steuerzonen ist geringfügig größer als die Rippenhöhe einer dem Grund des Kanals zugeordneten Tiefrippe, aber geringer ist als der Abstand der Scheitelfläche der Tiefrippe zum Boden einer der Tiefrippe benachbart liegenden Nut.Preferably, the cross-sectional shape of the control flanks is adapted to the control zones. The control zones essentially slide off in the line system on the control flanks. These have a rounded shape. The tip of at least one core pin forms a cylindrical extension. The bottom of the keyway has recesses for entry of the tip or cylindrical extension of the at least one core pin. The bottom of the channel forms a ramp for the tip of the core pin. This occurs only after an initial shift by the control edges against the ramp. The key is designed as a reversible flat key. A plurality of in the insertion direction of the key one behind the other core pins arranged in the lock cylinder. One or more core pins form at their tips cylindrical extensions. The ramp is associated with a Tiefrippe and a high rib of the key. The ramp extends over substantially the entire key thickness. The bottoms of two grooves flanking a high rib are assigned the control edges. These can also be assigned to the oblique walls of a deep rib. The control zones and the ramps have different angles to the key channel plane. The axial length of the control zones is slightly greater than the rib height of a tie rib associated with the bottom of the channel, but less than the pitch of the top surface of the tie rib to the bottom of a groove adjacent the tie rib.

Fig.1 zeigt einen Schlüssel 1 in einer perspektivischen Ansicht mit Blickrichtung auf die Schlüsselspitze. Der Schlüssel 1 ist als Wendeflachschlüssel ausgestaltet. Dieser bildet eine Schlüsselhandhabe 2 und einen Schlüsselschaft 3 aus. Der Schlüsselschaft 3 ist profiliert und weist an jeder seiner Breitseiten eine Hochrippe 4 und eine parallel dazu angeordnete Tiefrippe 5 auf. Wie in Fig. 6 zu sehen ist, ist der profilierte Schlüsselschaft 3 einem Schlüsselkanal 11 eines Zylinderkerns 7 formangepasst. Da es sich um einen Wendeflachschlüssel handelt, ist der Hochrippe 4 der einen Breitseite eine Tiefrippe 5 der anderen Breitseite gegenübergestellt. Die Hochrippe 4 weist hintereinander angeordnete in Schlüsselschafterstreckungsrichtung verschieden tiefe kegelförmige Senkungen 6 auf. Die Anzahl der Senkungen 6 ist der Anzahl der Stiftzuhaltungen angepasst. Die Senktiefe der Senkungen 6 ist von den Stiftzuhaltungen abhängig. Bei eingestecktem Schlüssel 1 in einen Zylinderkern 7 muss gewährleistet sein, dass sich die Trennebene der Zuhaltungen an der Mantelfläche des Zylinderkerns 7 befindet. Nur so ist ein Drehen des Zylinderkerns 7 in einem nicht dargestellten Schließzylinder möglich. Hier in dem Ausführungsbeispiel ist nur eine mögliche Variante dargestellt. Fig.1 shows a key 1 in a perspective view looking towards the key tip. The key 1 is designed as a reversible flat key. This forms a key handle 2 and a key shank 3. The key shank 3 is profiled and has on each of its broad sides a high rib 4 and a tie bar 5 arranged parallel thereto. As in Fig. 6 can be seen, the profiled key shank 3 a key channel 11 of a cylinder core 7 is shaped. Since it is a turning flat key, the high rib 4 of the one broad side is compared with a deep rib 5 of the other broad side. The raised rib 4 has cone-shaped depressions 6, which are arranged one behind the other in a key-member extension direction. The number of reductions 6 is adapted to the number of pin tumblers. The sinking depth of the counterbores 6 is dependent on the pin tumblers. When inserted key 1 in a cylinder core 7 must be ensured that the parting plane of the tumblers on the lateral surface of the cylinder core 7 is. Only then is a turning of the cylinder core 7 in a lock cylinder, not shown, possible. Here in the embodiment, only one possible variant is shown.

Die Tiefrippe 5 weist eine Stufe 8 auf. Diese geht in einen höhenverminderten Tiefrippenbereich 5' über. Vor der Stufe 8 in Richtung der Schlüsselspitze ist eine Senkung 9 eingearbeitet. In die Senkung 9 kann ein Zusatzstift 10 hineingreifen.The deep rib 5 has a step 8. This goes into a reduced height tufa region 5 'over. Before level 8 in the direction of the key tip a countersink 9 is incorporated. In the countersink 9, an additional pin 10 reach into it.

In Fig. 2 ist die Schlüsselspitze in einem Ausschnitt vergrößert dargestellt. Dort ist zu sehen, dass ausgehend von der Tiefrippe 5 bis zur Hochrippe 4 ein Kanal 12 verläuft. Der Kanal 12 verläuft spitzwinklig von der Tiefrippe 5, in Richtung der Schlüsselhandhabe 2 bis zur Hochrippe 4. Der Grund des Kanals 12 bildet eine Auflaufschräge 13 für eine Spitze 14 eines Kernstiftes 15 oder für die Spitze 16 des zylindrischen Fortsatzes 17 eines Kernstiftes 18 aus. Die Auflaufschräge 13 ist konkav gerundet und ist somit dem Verlagerungsweg der Spitzen 14,16 formangepasst. Des Weiteren ist die Auflaufschräge 13 der Tiefrippe 5 und auch der Hochrippe 4 zugeordnet. Die Auflaufschräge 13 verläuft im Wesentlichen über die gesamte Schlüsselschaftdicke.In Fig. 2 the key tip is enlarged in a detail. There it can be seen that starting from the deep rib 5 to the high rib 4, a channel 12 runs. The channel 12 extends at an acute angle from the tie bar 5, in the direction of the key handle 2 to the high rib 4. The bottom of the channel 12 forms a ramp 13 for a tip 14 of a core pin 15 or the tip 16 of the cylindrical extension 17 of a core pin 18. The run-up slope 13 is concavely rounded and is thus adapted to the displacement path of the tips 14,16. Furthermore, the run-on slope 13 of the tie-bar 5 and also the high-rib 4 is assigned. The ramp 13 extends substantially over the entire key shank thickness.

Die Schlüsselspitze bildet eine Gabelöffnung 19 aus. Mit dieser Gabelöffnung 19 kann die Schlüsselspitze den zylindrischen Fortsatzes 17 des Kernstiftes 18 umragen.The key tip forms a fork opening 19. With this fork opening 19, the key tip can project around the cylindrical extension 17 of the core pin 18.

Seitlich der Hochrippe befindet sich jeweils eine Nut 20. Die beiden Nuten 20 flankieren die Hochrippe 4. Den Böden der Nuten 20 ist jeweils eine Steuerflanke 21 zugeordnet. Somit sind die Steuerflanken 21 auch den schrägen Wandungen der Tiefrippe 5 zugeordnet. Die Steuerflanken 21 weisen eine gerundete Gestalt auf und sind somit der Form der Steuerzonen 22 der Kernstifte 15, 18 formangepasst.Each side of the high rib is a groove 20. The two grooves 20 flank the high rib 4. The bottoms of the grooves 20 each have a control edge 21 assigned. Thus, the control edges 21 are also assigned to the oblique walls of the tie rib 5. The control flanks 21 have a rounded shape and are thus adapted to the shape of the control zones 22 of the core pins 15, 18.

In der Fig. 4 ist der Zylinderkern 7 im Schnitt dargestellt. Es ist gut zu erkennen, dass mehrere Kernstifte 15, 18 hintereinander angeordnet sind. Diese liegen in Schlüsseleinsteckrichtung hintereinander. Der Kernstift 15 weist eine kreiszylindrische Grundkontur auf. Die Steuerzone 22 wird von einem kegelförmigen Ende gebildet. Das kegelförmige Ende des Kernstiftes 15 ragt in den Schlüsselkanal 11 hinein. Die Kernstifte 15 weisen unterschiedliche Längen auf. Des Weiteren ist ein Kernstift 18 in dem Zylinderkern 7 angeordnet. Der Kernstift 18 weist ebenfalls ein kegelförmiges Ende auf. Dieses bildet die Steuerzone 22. Auf dem kegelförmigen Ende ist ein zylindrischer Fortsatz 17 angeordnet. Dieser weist einen geringeren Querschnitt auf als der Kernstift 18. Zum unteren Ende des Kernstiftes 18 bildet dieser einen kegelförmigen Abschnitt 23 aus.In the Fig. 4 the cylinder core 7 is shown in section. It is good to see that several core pins 15, 18 are arranged one behind the other. These are in Schlüsseleinsteckrichtung behind the other. The core pin 15 has a circular cylindrical basic contour. The control zone 22 is formed by a conical end. The conical end of the core pin 15 protrudes into the keyway 11. The core pins 15 have different lengths. Furthermore, a core pin 18 is disposed in the cylinder core 7. The core pin 18 also has a tapered end. This forms the control zone 22. On the conical end, a cylindrical extension 17 is arranged. This has a smaller cross-section than the core pin 18. The lower end of the core pin 18 of this forms a conical portion 23 from.

Dieser geht dann in einen Abschnitt 24 über, der der Grundkontur des Kernstiftes 18 formangepasst ist.This then passes into a section 24, which is the form of the basic contour of the core pin 18.

In dem Zylinderkern 7 sind für die Kernstifte 15,18 Kernstiftbohrungen 25 vorgesehen. Diese verlaufen in einem rechten Winkel zur Verlaufsrichtung des Schlüsselkanals 11. Die Kernstiftbohrungen 25 sind in der Fig. 4 unterhalb des Schlüsselkanals 11 angeordnet. Oberhalb des Schlüsselkanals 11 sind Zusatzbohrungen 26 angeordnet. Die Zusatzbohrungen 26 weisen an ihrem oberen Ende einen durchmesservergrößerten Abschnitt 27 auf. In einer der Zusatzbohrungen 26 liegt ein Zusatzstift 10 ein. Der Zusatzstift 10 weist ebenfalls an seinem oberen Ende einen durchmessergrößeren Abschnitt 28 auf. Am Ende des Abschnitts 28 ist ein Konusabschnitt 29 angeordnet. Der Abschnitt 28 ist dem Abschnitt 27 der Zusatzbohrung 26 angepasst. An seinem unteren Ende bildet der Zusatzstift 10 einen weiteren Konusabschnitt 30 aus. Die Zusatzbohrungen 26 liegen leicht versetzt zu den Kernstiftbohrungen 25. Somit bieten die Zwischenräume zwischen den Zusatzbohrungen 26 eine Anlagefläche 31 für die Kernstifte 15. Für den zylindrischen Abschnitt 17 des Kernstiftes 18 ist in dem Zylinderkern 7 eine Vertiefung 32 eingearbeitet. Die Vertiefung 32 ist dem zylindrischen Abschnitt 17 des Kernstiftes 18 formangepasst. Somit befinden sich die Steuerzonen 22 der Kernstifte 15, 18 auf einem gleichen Höhenniveau bei nicht eingestecktem Schlüssel 1.In the cylinder core 7 15.18 core pin holes 25 are provided for the core pins. These run at a right angle to the direction of the keyway 11. The core pin holes 25 are in the Fig. 4 arranged below the keyway 11. Above the keyway 11 additional holes 26 are arranged. The additional bores 26 have at their upper end an enlarged diameter portion 27. In one of the additional bores 26 is an additional pin 10 a. The additional pin 10 also has a larger diameter portion 28 at its upper end. At the end of the section 28, a cone section 29 is arranged. The section 28 is adapted to the section 27 of the additional bore 26. At its lower end, the additional pin 10 forms a further cone section 30. The additional holes 26 are slightly offset from the core pin holes 25. Thus, the spaces between the additional holes 26 provide a contact surface 31 for the core pins 15. For the cylindrical portion 17 of the core pin 18, a recess 32 is incorporated in the cylinder core 7. The recess 32 is adapted to the cylindrical portion 17 of the core pin 18. Thus, the control zones 22 of the core pins 15, 18 are at the same height level with the key 1 not inserted.

Die Kernstifte 15, 18 sind rotationssymmetrisch gestaltet. Durch die rotationssymmetrische Gestalt der Kernstifte 15, 18 wird eine kostengünstigere Fertigung erzielt.The core pins 15, 18 are designed rotationally symmetrical. Due to the rotationally symmetrical shape of the core pins 15, 18 a more cost-effective production is achieved.

Die an der Schlüsselspitze eingearbeitete Auflaufschräge 13 und die Steuerflanken 21 können einen unterschiedlichen Winkel zur Schlüsselkanalebene besitzen. Durch unterschiedliche Winkel zueinander wird erreicht, dass sich der Kernstift 15,18 je nach Winkel unterschiedlich schnell bei gleichbleibender Einsteckgeschwindigkeit des Schlüssels 1 verlagert. Beispielsweise können die Steuerflanken 21 einen spitzeren Winkel zur Schlüsselkanalebene aufweisen als die Auflaufschräge 13. Durch diese Gestaltung wird erreicht, dass am Anfang die Kernstifte 15,18 langsam verlagert werden und somit ein Verkanten der Kernstifte 15,18 im Zylinderkern 7 verhindert wird. Gleiten die Kernstifte 15, 18 anschließend auf der Auflaufschräge 13 ab, so verlagern sich diese schneller.The incorporated on the key tip bevel 13 and the control edges 21 may have a different angle to the key channel level. By different angles to one another it is achieved that the core pin 15,18 moves depending on the angle at different speeds with the same insertion speed of the key 1. For example, the Control edges 21 have a more acute angle to the key channel plane than the ramp 13. This design ensures that the core pins 15,18 are slowly displaced at the beginning and thus tilting of the core pins 15,18 in the cylinder core 7 is prevented. Sliding the core pins 15, 18 then on the ramp 13, so they shift faster.

In Fig. 6 ist gut verdeutlicht, dass die axiale Länge a der Steuerzone 22 der Kernstifte 15, 18 geringfügig größer ist als die Rippenhöhe b einer dem Grund 33 des Schlüsselkanals 11 zugeordneten Tiefrippe 5. Die axiale Länge a der Steuerzone 22 ist geringer als der Abstand c der Scheitelfläche 34 der Tiefrippe 5 zum Boden der Tiefrippe 5 benachbart liegenden Nut 20.In Fig. 6 is well illustrated that the axial length a of the control zone 22 of the core pins 15, 18 is slightly larger than the rib height b of the base 33 of the keyway 11 associated Tiefrippe 5. The axial length a of the control zone 22 is less than the distance c of the vertex surface 34 of the tie rib 5 to the bottom of the tie rib 5 adjacent groove 20th

Es stellt sich folgende Wirkungsweise ein:The following mode of action occurs:

Ausgehend von der Fig. 4 sind die Kernstifte 15,18 und der Zusatzstift 10 in ihrer Grundstellung. Die Kernstifte 15,18 sind Teil einer Zuhaltung, die hier nicht näher dargestellt wird. Zu der Zuhaltung gehören noch Gehäusestifte, die von Federn beaufschlagt werden. Die Federn wirken in Richtung des Schlüsselkanals 11. In dieser Position würden die Gehäusestifte den Zylinderkern 7 gegen ein Drehen sichern. Erst durch einen passenden Schlüssel 1 wäre es möglich, die Kernstifte 15, 18 sowie die nicht dargestellten Gehäusestifte derart zu verlagern, dass die Trennebene zwischen den Kernstiften 15,18 und den Gehäusestiften mit der Mantelfläche des Zylinderkerns 7 fluchtet. Dann ist es erst möglich, den Zylinderkern zu drehen.Starting from the Fig. 4 are the core pins 15,18 and the additional pin 10 in its normal position. The core pins 15,18 are part of a tumbler, which is not shown here. To the tumbler still include housing pins, which are acted upon by springs. The springs act in the direction of the key channel 11. In this position, the housing pins would secure the cylinder core 7 against rotation. Only by a suitable key 1, it would be possible to relocate the core pins 15, 18 and the housing pins, not shown, such that the parting plane between the core pins 15,18 and the housing pins is aligned with the lateral surface of the cylinder core 7. Then it is only possible to turn the cylinder core.

In der Fig. 5 wurde der Schlüssel 1 soweit in den Schlüsselkanal 11 hineingesteckt, dass die Steuerflanken 21 an den Steuerzonen 22 des ersten Kernstiftes 15 anliegen. Die Steuerzonen 22 liegen im Wesentlichen in einer Linienanlage an den Steuerflanken 21 an. Durch die Linienanlage der Steuerzonen 22 an den Steuerflanken 21 wird ein geringerer Verschleiß der Kernstifte 15 erreicht. Wenn nun der Schlüssel 1 weiter in den Schlüsselkanal 11 hineingesteckt wird, so verlagert sich der Kernstift 15 aus dem Schlüsselkanal 11 hinaus. Am Anfang seiner Verlagerung wird der Kernstift 15 nur mittelst des Zusammenspiels der Steuerflanken 21 und der Steuerzonen 22 verlagert. Nach einem gewissen Verlagerungsweg des Kernstiftes 15 wird die Position erreicht, die in den Figuren 9 bis 11 dargestellt worden ist. Nun wird der Kernstift 15 mittelst der Auflaufschräge 13 weiter aus dem Schlüsselkanal 11 verlagert. Die Spitze 14 des Kernstiftes 15 läuft dabei auf der Auflaufschräge 13 ab.In the Fig. 5 the key 1 was inserted into the keyway 11 far enough that the control flanks 21 rest against the control zones 22 of the first core pin 15. The control zones 22 are essentially in line with the control flanks 21. Due to the line system of the control zones 22 on the control flanks 21, a lesser wear of the core pins 15 is achieved. Now, if the key 1 is further inserted into the key channel 11, Thus, the core pin 15 moves out of the keyway 11 addition. At the beginning of its displacement of the core pin 15 is only mediated by the interaction of the control edges 21 and the control zones 22. After a certain displacement of the core pin 15, the position is reached in the FIGS. 9 to 11 has been shown. Now, the core pin 15 by means of the ramp 13 is further displaced from the keyway 11. The tip 14 of the core pin 15 runs on the ramp bevel 13 from.

Wie in den Figuren 12 bis 14 zu sehen ist, liegen nun die Steuerflanken 21 an den Steuerzonen 22 des Kernstiftes 18 an. Der zylindrische Abschnitt 17 liegt dabei in der Gabelöffnung 19 ein. Nach einem gewissen Verlagerungsweg des Kernstiftes 18 gleitet nun die Spitze 16 des zylindrischen Abschnitts 17 auf der Auflaufschräge 13 ab (siehe Figuren 15 bis 17).As in the FIGS. 12 to 14 can be seen, are now the control edges 21 at the control zones 22 of the core pin 18 at. The cylindrical portion 17 lies in the fork opening 19 a. After a certain displacement of the core pin 18 now slides the tip 16 of the cylindrical portion 17 on the ramp 13 from (see FIGS. 15 to 17 ).

Wird nun der Schlüssel 1 vollständig in den Schlüsselkanal 11 eingesteckt, verlagern sich die Kernstifte 15, 18 derart, dass jede Spitze 14, 16 in einer passenden Senkung 6 des Schlüsselschaftes 3 einliegt. Der Konusabschnitt 30 des Zusatzstiftes 10 liegt dann in der Senkung 9 der gegenüberliegenden Tiefrippe 5 ein. Werden nun, wie in der DE 102004003034.0 die Senkungen 6 tiefer als die Maximaltiefe des Systems eingearbeitet, so entsteht durch den verminderten Tiefrippenbereich 5' ein Durchgangsloch im Schlüsselschaft 3. In dieses Durchgangsloch kann der zylindrische Abschnitt 17 des Kernstifts 18 hineintreten und den Schlüssel, der für die Perkussionstechnik benötigt wird, fesseln. Ein Drehen des Zylinderkerns 7 ist nicht mehr möglich.Now, if the key 1 is completely inserted into the keyway 11, the core pins 15, 18 shift so that each tip 14, 16 rests in a matching countersink 6 of the key shank 3. The cone portion 30 of the additional pin 10 is then in the reduction 9 of the opposite tie rib 5 a. Now, as in the DE 102004003034.0 the recesses 6 incorporated deeper than the maximum depth of the system, so by the reduced Tiefrippenbereich 5 ', a through hole in the key shank 3. In this through hole, the cylindrical portion 17 of the core pin 18 can enter and tie the key that is needed for percussion. Turning the cylinder core 7 is no longer possible.

Durch die rotationssymmetrische Gestaltung der Kernstifte 15, 18 wird erreicht, dass diese kostengünstiger hergestellt werden können und die dafür vorgesehenen Kernstiftbohrungen 25 nicht mehr für den Profilquerschnitt der sonstigen Kernstifte angepasst werden muss. Ebenfalls braucht nicht mehr darauf geachtet zu werden, dass die Kernstifte 15,18 in einer bestimmten Stellung zu den Kernstiftbohrungen 25 eingesetzt werden. Da die Kernstifte 15,18 keinen Steg mehr ausbilden, sind diese stabiler gestaltet. Durch die Linienanlage der Steuerzonen 22 an den Steuerflanken 21 wird ein geringerer Verschleiß erreicht.Due to the rotationally symmetrical design of the core pins 15, 18 ensures that they can be produced more cheaply and the designated core pin holes 25 no longer needs to be adapted for the profile cross section of the other core pins. Likewise, it no longer needs to be taken to ensure that the core pins 15, 18 are inserted in a specific position relative to the core pin bores 25. Since the core pins 15,18 no Bridge more training, these are designed more stable. Due to the line system of the control zones 22 on the control flanks 21 a lesser wear is achieved.
