They are at the key and are also spaced from the end sides (12) of the lock cylinder (1) to define the full key insertion into the lock. The limits are an integr part of the key, and can be recesses or raised zones.

Description

Die Erfindung betrifft ein Schließsystem mit einem einen Schlüsselkanal sowie eine Mehrzahl von Zuhaltungen aufweisenden Schließzylinder und einem Schlüssel, mittels welchem die Zuhaltungen bei in den Schlüsselkanal eingeführtem Schlüssel beaufschlagbar sind, wobei sowohl schließzylinderseitig als auch schlüsselseitig Anschlagelemente vorgesehen sind, die die maximale Einschubtiefe des Schlüssels in den Schlüsselkanal definieren.The invention relates to a locking system with a key channel and a plurality of locking cylinders and tumblers a key, by means of which the tumblers in the key channel introduced key are acted upon, both Stop elements are provided on the lock cylinder side and also on the key side are the maximum depth of insertion of the key into the key channel define.

Derartige Schließsysteme sind hinreichend bekannt, es besteht jedoch generell das Bedürfnis, die Schlüssel derartiger Schließsysteme in einem höchstmöglichen Maß gegen unbefugte Nachahmung zu sichern und die Anzahl der für die unterschiedlichen Schlüssel eines Schließsystems möglichen Permutationen zu erhöhen.Locking systems of this type are well known, but they generally exist the need for the keys of such locking systems in one secure the highest possible level against unauthorized imitation and the Number of possible for the different keys of a locking system To increase permutations.

Zu diesem Zweck wird erfindungsgemäß vorgeschlagen, daß sämtliche Anschlagelemente beabstandet zur Schlüsselspitze derart angeordnet sind, daß sie sich bei vollständig in den Schlüsselkanal eingeführtem Schlüssel innerhalb des Schlüsselkanals befinden und somit auch beabstandet zu den Stirnseiten des Schließzylinders zu liegen kommen.For this purpose, the invention proposes that all Stop elements arranged at a distance from the key tip are that they are fully inserted into the key channel Keys are located within the key channel and are therefore also spaced apart come to rest on the front sides of the locking cylinder.

Dieses Merkmal stellt einen wesentlichen Unterschied zu Schließsystemen gemäß Stand der Technik dar, da bei bekannten Schließsystemen üblicherweise am Schlüssel lediglich ein Anschlagelement vorgesehen ist, welches sich zwischen Schlüsselkopf und Schlüsselschaft befindet und das bei eingestecktem Schlüssel mit einer Stirnseite des Schließzylinders zusammenwirkt. Erfindungsgemäß wird ein solches Zusammenwirken im Bereich einer Stirnseite des Schließzylinders gerade vermieden, da sich sämtliche Anschlagelemente bei in den Schlüsselkanal eingeführtem Schlüssel innerhalb des Schlüsselkanals zum einen beabstandet von der Schlüsselspitze und zum anderen auch beabstandet von den Stirnseiten des Schließzylinders befinden. Dies hat auf vorteilhafte Weise zur Folge, daß handelsübliche Schlüsselrohlinge nicht zur Herstellung von unbefugten Nachahmungen genutzt werden können, da diese Schlüsselrohlinge keine erfindungsgemäß positionierten Anschlagelemente aufweisen.This feature makes a significant difference to locking systems according to the prior art, as is usually the case with known locking systems only a stop element is provided on the key, which is between the key head and key shaft and that interacts with an end face of the locking cylinder when the key is inserted. According to the invention, such interaction is in the Area of an end face of the lock cylinder just avoided, because all stop elements when inserted into the key channel Key within the key channel on the one hand spaced from the Key tip and on the other hand also spaced from the end faces of the locking cylinder. This has the advantageous result that commercially available key blanks are not used to manufacture unauthorized persons Imitations can be used as these key blanks have no stop elements positioned according to the invention.

Zudem kann durch die erfindungsgemäßen Anschlagelemente erreicht werden, daß bei von Schließsystem zu Schließsystem unterschiedlicher Ausbildung und/oder Anordnung der Anschlagelemente zusätzliche Permutationsmöglichkeiten hinsichtlich der Anzahl der unterschiedlichen, zur Verfügung stehenden Schlüssel geschaffen werden.In addition, can be achieved by the stop elements according to the invention be that different from locking system to locking system Training and / or arrangement of the stop elements additional permutation options in terms of the number of different available keys are created.

Bevorzugt ist es, wenn Schlüssel und/oder Schließzylinder genau ein Anschlagelement aufweisen. Alternativ ist es jedoch auch möglich, an Schlüssel und/oder Schließzylinder zwei oder mehr Anschlagelemente vorzusehen.It is preferred if the key and / or locking cylinder have exactly one stop element exhibit. Alternatively, it is also possible to Key and / or lock cylinder two or more stop elements provided.

Die miteinander zusammenwirkenden Anschlagflächen der Anschlagelemente können sich senkrecht zur Längsachse des Schließzylinders erstrecken, jedoch auch eine schräge Ausrichtung zur Längsachse des Schließzylinders ist grundsätzlich möglich.The interacting stop surfaces of the stop elements can extend perpendicular to the longitudinal axis of the locking cylinder, however also an oblique orientation to the longitudinal axis of the Lock cylinder is basically possible.

Das Anschlagelement des Schlüssels kann am Schlüsselrücken, an einer oder an beiden Breitseiten des Schlüssels oder im Bereich des Schlüsselbarts angeordnet werden. Bei Vorsehung von mehreren Anschlagelementen an einem Schlüssel ist es möglich, diese Anschlagelemente an einem einzelnen oder an unterschiedlichen der vorstehend genannten Bereiche anzuordnen.The stop element of the key can be on the back of the key, on a or on both broad sides of the key or in the area of the key bit to be ordered. If several stop elements are provided on a key it is possible to attach these stop elements to one individual or in different of the aforementioned areas to arrange.

Das bzw. die Anschlagelemente können bei einer besonders wirtschaftlichen Ausführungsform eines erfindungsgemäßen Systems als integrale Bestandteile des Schlüssels ausgebildet sein.The stop element or elements can be particularly economical Embodiment of a system according to the invention as an integral Be formed components of the key.

Bei Verwendung von symmetrischen Flachschlüsseln ist es bevorzugt, wenn auf beiden Breitseiten des Schlüssels jeweils ein Anschlagelement vorgesehen ist, wobei beide Anschlagelemente symmetrisch zueinander angeordnet sind. In diesem Fall kann der Schlüssel in zwei um 180° zueinander versetzten Orientierungen in den zugehörigen Schließzylinder eingeführt werden.When using symmetrical flat keys, it is preferred if a stop element on both broad sides of the key is provided, both stop elements symmetrical to each other are arranged. In this case the key can be turned 180 ° to each other offset orientations in the associated locking cylinder be introduced.

Das Anschlagelement des Schlüssels wird bevorzugt durch eine Vertiefung oder eine Hervorhebung gebildet. Es kann weiterhin bei verschiedenen Schlüsseln bezogen auf die Längsachse des Schlüssels an unterschiedlichen Positionen angeordnet sein, wodurch - wie bereits erwähnt - eine Erhöhung der Permutationsmöglichkeiten erreicht wird.The stop element of the key is preferably through a recess or a highlight. It can continue at various Keys related to the longitudinal axis of the key at different Positions are arranged, which - as already mentioned - an increase of the permutation possibilities is reached.

Zusätzliche Permutationsmöglichkeiten können auch dadurch geschaffen werden, daß das als Vertiefung bzw. Hervorhebung ausgebildete Anschlagelement des Schlüssels bei verschiedenen Schlüsseln unterschiedliche Tiefen bzw. Höhen aufweist. This can also create additional permutation options be that the stop element designed as a recess or highlighting the key for different keys different Has lows or highs.

Im Bereich zwischen Schlüsselkopf und Schlüsselschaft kann zusätzlich zu dem beschriebenen Anschlagelement ein Bezugselement vorgesehen werden, welches zur Herstellung eines zu einem bestimmten Schließsystem passenden Schlüssels verwendbar ist. Ein derartiges Bezugselement ist für das Fräsen von Schlüsseln hilfreich, um die durch den Fräsvorgang in einen Schlüsselrohling eingebrachten Einschnitte und Ausnehmungen relativ zur Schlüssellängsachse korrekt positionieren zu können.In the area between the key head and key shaft, additional a reference element is provided for the stop element described which are used to manufacture a locking system for a particular system suitable key can be used. Such a reference element is helpful for milling keys to get through the milling process incisions and recesses made in a key blank to be able to position correctly relative to the key longitudinal axis.

Von Vorteil ist es, wenn dieses Bezugselement als Anschlag ausgebildet wird, so daß der Schlüssel letztlich einen ersten Anschlag aufweist, welcher als Bezugselement für den Fräsvorgang verwendet wird und weiterhin zumindest einen weiteren Anschlag besitzt, der erfindungsgemäß bei vollständig in den Schlüsselkanal eingeführtem Schlüssel innerhalb des Schlüsselkanals zu liegen kommt und die Einstecktiefe des Schlüssels begrenzt.It is advantageous if this reference element is designed as a stop is, so that the key ultimately has a first stop, which is used as a reference element for the milling process and continues has at least one further stop, which according to the invention is complete key inserted into the key channel within the Key channel comes to rest and limits the depth of insertion of the key.

Bevorzugt ist das genannte Bezugselement derart angeordnet, daß es sich bei vollständig in den Schlüsselkanal eingeführtem Schlüssel außerhalb des Schlüsselkanals, beabstandet zu den Stirnseiten des Schließzylinders befindet. Dies bedeutet, daß das Bezugselement nicht etwa einen zusätzlichen Anschlag für die Begrenzung der Einstecktiefe des Schlüssels darstellt, da es bei vollständig eingestecktem Schlüssel aufgrund des genannten Abstands keinen Kontakt zum Schließzylinder bzw. dessen Stirnseiten besitzt. Die einzige Funktion des Bezugselements ist somit tatsächlich die Schaffung eines Bezugspunkts für den Fräsvorgang bei der Herstellung des Schlüssels. Preferably, the said reference element is arranged such that it with the key completely inserted into the key channel outside of the key channel, spaced from the end faces of the locking cylinder located. This means that the reference element is not an additional one Represents the limit for the depth of insertion of the key, since it is due to the above when the key is fully inserted Clearance, no contact with the locking cylinder or its end faces has. The only function of the reference element is therefore actually the creation of a reference point for the milling process during manufacture of the key.

Das Bezugselement kann vorzugsweise als herkömmliche Schlüsselreide ausgebildet werden, was die Wirtschaftlichkeit des Herstellungsprozesses erhöht, da hinsichtlich der Herstellung des Bezugselements keine bisher nicht üblichen Arbeitsgänge nötig sind.The reference element can preferably be used as a conventional key chalk be trained in what the economics of the manufacturing process increased, since none with regard to the production of the reference element normal operations are not necessary.

Besonders von Vorteil ist es, wenn das Bezugselement des Schlüssels bei verschiedenen Schlüsseln bezogen auf die Längsachse des Schlüssels an unterschiedlichen Positionen angeordnet ist. Hierdurch werden zusätzliche Permutationsmöglichkeiten geschaffen.It is particularly advantageous if the reference element of the key different keys related to the longitudinal axis of the key different positions is arranged. This will make additional Permutation opportunities created.

Bevorzugt wird das Anschlagelement des Schließzylinders stationär ausgebildet. Ein solches stationäres Anschlagelement kann beispielsweise in eine Ausnehmung eines Schließzylinderkerns eingesetzt werden, wodurch eine kostengünstige und wirtschaftliche Fertigung eines erfindungsgemäßen Schließzylinders möglich wird.The stop element of the locking cylinder is preferably designed to be stationary. Such a stationary stop element can, for example, in a recess of a lock cylinder core are used, whereby an inexpensive and economical manufacture of an inventive Lock cylinder is possible.

Es ist jedoch auch möglich, das Anschlagelement des Schließzylinders als bewegliche Zuhaltung auszubilden. Diese Zuhaltung stellt dann zum einen das Anschlagelement für ein entsprechendes Anschlagelement des Schlüssels dar und wird zum anderen - unter Schaffung einer weiteren Permutationsmöglichkeit - durch einen passenden Schlüssel in eine solche Position bewegt, die ein Drehen des Zylinderkerns im Schließzylinder ermöglicht. Die Zuhaltung erfüllt somit in diesem Fall eine Doppelfunktion.However, it is also possible to use the stop element of the locking cylinder to train movable guard locking. On the one hand, this tumbler represents the stop element for a corresponding stop element of the Key and becomes another - creating another Permutation possibility - with a suitable key in one Position that moves a turning of the cylinder core in the locking cylinder allows. The guard locking therefore fulfills a double function in this case.

Mit der Erfindung wird nicht nur das Schließsystem, sondern zudem auch ein im Rahmen der Erfindung verwendbarer Schlüssel sowie ein im Rahmen der Erfindung verwendbarer Schlüsselrohling geschützt. Der Schlüssel kann dabei eines oder mehrere der vorstehend genannten Merkmale aufweisen.With the invention not only the locking system, but also a key which can be used in the context of the invention and a key which can be used in the framework key blank usable according to the invention protected. The key can be one or more of the features mentioned above exhibit.

Entsprechendes gilt für einen erfindungsgemäßen Schlüsselrohling. Ein solcher Schlüsselrohling kann bevorzugt im Bereich zwischen Schlüsselkopf und Schlüsselschaft ein Bezugselement gemäß den vorstehend in Verbindung mit dem erfindungsgemäßen Schließsystem beschriebenen Merkmalen aufweisen.The same applies to a key blank according to the invention. On such a key blank can preferably be in the area between the key head and key shank a reference element according to the above in Connection described with the locking system according to the invention Have features.

Diese Ausnehmung 14 bildet ein Anschlagelement, welches mit einem im Schließzylinderkern 1' vorgesehenen Anschlagelement 15 zusammenwirkt. Das Anschlagelement 15 weist ebenso wie die Ausnehmung 14 eine senkrecht zur Längsachse des Schlüsselschaftes 8 verlaufende Anschlagfläche auf, wobei die beiden erwähnten Anschlagflächen bei vollständig in den Schlüsselkanal 2 eingeführtem Schlüssel 3 aneinander anliegen und dadurch die maximale Einschubtiefe des Schlüssels 3 begrenzen. Bei der Ausführungsform gemäß Fig. 1 wird somit die maximale Einschubtiefe des Schlüssels 3 in den Schlüsselkanal 2 ausschließlich durch das Zusammenwirken des Anschlagelements 15 mit der Ausnehmung 14 begrenzt.On the back of the key 13, which in the area of the key shaft 8 Notches 9 opposite one another is on the key head 10 facing away End provided a recess 14. This recess 14 forms a stop element, which with a in the lock cylinder core 1 ' provided stop element 15 cooperates. The stop element 15, like the recess 14, has a perpendicular to the longitudinal axis of the key shaft 8 extending stop surface, the two mentioned stop surfaces with fully inserted into the key channel 2 Key 3 lie against each other and thereby the maximum Limit insertion depth of key 3. In the embodiment according to Fig. 1 is thus the maximum insertion depth of the key 3 in the Key channel 2 only through the interaction of the stop element 15 limited with the recess 14.

Fig. 2a zeigt einen schematischen Schnitt durch einen Schließzylinder 1 im Bereich des Anschlagelements 15 entsprechend Fig. 1. Die genannte Darstellung veranschaulicht, daß in den Schließzylinderkern 1', welcher drehbar im Schließzylinder 1 gelagert ist, von oben ein Einschnitt eingebracht wurde, in den das kreissegmentförmige Anschlagelement 15 eingesetzt ist. Das Anschlagelement 15 kann dabei beispielsweise mit Preßsitz in den Schließzylinder 1 eingepaßt, mit einem geeigneten Klebstoff fixiert oder auch nur lose im Einschnitt gehalten sein.2a shows a schematic section through a locking cylinder 1 in the area of the stop element 15 corresponding to FIG. 1. The above Illustration illustrates that in the lock cylinder core 1 ', which is rotatably mounted in the lock cylinder 1, an incision made from above was used in the circular segment-shaped stop element 15 is. The stop element 15 can, for example, with a press fit fitted in the lock cylinder 1, fixed with a suitable adhesive or be held loosely in the incision.

Der in den Schließzylinderkern 1' eingebrachte Einschnitt sowie das Anschlagelement 15 sind so bemessen, daß sich das Anschlagelement 15 bis in den oberen Bereich des Schlüsselkanals 2 erstreckt, so daß eine die Einschubtiefe des Schlüssels 3 begrenzende Wechselwirkung zwischen Anschlagelement 15 und Schlüssel 3 erzielbar ist.The incision made in the locking cylinder core 1 'and the stop element 15 are dimensioned so that the stop element 15 to extends into the upper region of the key channel 2, so that a Interaction depth of the key 3 limiting interaction between Stop element 15 and key 3 can be achieved.

Bei dem in den Fig. 1 und 2a dargestellten Anschlagelement 15 handelt es sich um ein stationäres Anschlagelement, welches nicht die Funktion einer Zuhaltung erfüllt. Jedoch ist es auch durch das Anschlagelement 15 möglich, die Anzahl der Permutationen eines Schlüssels zu erhöhen, indem beispielsweise bei unterschiedlichen Schließzylindern das Anschlagelement 15 an unterschiedlichen Positionen bezogen auf die Längsachse des Schließzylinders bzw. des Schlüsselschafts angeordnet wird oder indem das Maß, in dem das Anschlagelement 15 in den Schlüsselkanal 2 quer zu dessen Längsachse hineinragt, variiert wird.The stop element 15 shown in FIGS. 1 and 2a is concerned is a stationary stop element that does not function as a Guard locking met. However, it is also due to the stop element 15 possible to increase the number of permutations of a key by for example, the stop element in the case of different locking cylinders 15 at different positions related to the longitudinal axis the lock cylinder or the key shaft is arranged or by the extent to which the stop element 15 in the key channel 2nd protrudes transversely to its longitudinal axis, is varied.

Stationäre Anschlagelemente lassen sich in Abweichung von den Fig. 1 und 2a auch in beliebigen anderen Ausführungsformen realisieren, von denen in den Fig. 2b und 2c zwei Beispiele veranschaulicht sind.Stationary stop elements can be deviated from FIG. 1 and 2a also realize in any other embodiment of which are illustrated in Figures 2b and 2c two examples.

Fig. 2b zeigt einen Stift oder Draht 16, welcher in eine horizontal verlaufende Bohrung des Schließzylinderkerns 1' eingebracht und dort fixiert ist. Die den Stift/Draht 16 aufnehmende Bohrung durchdringt dabei den Schlüsselkanal 2, so daß die genannte Wechselwirkung zwischen Stift/Draht 16 und Anschlagfläche des Schlüssels 3 erzielt werden kann.Fig. 2b shows a pin or wire 16 which is in a horizontal Bore of the lock cylinder core 1 'introduced and fixed there. The hole receiving the pin / wire 16 penetrates the Key channel 2, so that the interaction between Pen / wire 16 and stop surface of the key 3 can be achieved.

In Fig. 2c ist ein U-förmig gebogenes Drahtelement 17 gezeigt, welches mit seinen beiden Schenkeln in vertikal verlaufenden Bohrungen des Schließzylinderkerns 1' fixiert ist. Das die beiden Schenkel 18 verbindende Basiselement 19 des Drahtelements 17 bildet dabei die in den Schlüsselkanal 2 ragende Anschlagfläche für den Schlüssel 3.In Fig. 2c, a U-shaped wire element 17 is shown, which with its two legs in vertical bores of the lock cylinder core 1 'is fixed. The base element connecting the two legs 18 19 of the wire element 17 forms the key channel 2 protruding stop surface for the key 3.

Fig. 2d entspricht im wesentlichen Fig. 2c mit dem Unterschied, daß sich an die Unterseite der beiden Schenkel 18 des Drahtelements 17 noch zwei kurze Stiftelemente 20 anschließen, die durch jeweils eine Feder 21 beaufschlagt sind. Das Drahtelement 17 gemäß Fig. 2d ist somit durch das Einschieben des Schlüssels 3 in den Schlüsselkanal 2 in vertikaler Richtung beaufschlagbar und stellt auf diese Weise eine zusätzliche Zuhaltung dar. Bei vollständig in den Schlüsselkanal 2 eingeschobenem Schlüssel 3 befinden sich die Grenzflächen zwischen Schenkeln 18 und Stiftelementen 20 in einer solchen Position, die ein Verdrehen des Zylinderkerns 1' im Schließzylinder 1 ermöglicht.Fig. 2d essentially corresponds to Fig. 2c with the difference that on the underside of the two legs 18 of the wire element 17 two more Connect short pin elements 20, which are each acted upon by a spring 21 are. The wire element 17 according to FIG. 2d is thus inserted of the key 3 in the key channel 2 in the vertical direction actable and thus represents an additional guard locking. With the key 3 fully inserted into the key channel 2 the interfaces between legs 18 and pin elements 20 in such a position that a rotation of the cylinder core 1 'in Lock cylinder 1 allows.

Wie bereits erwähnt, kann anstelle des Drahtelements 17 auch eine beliebige andere Zuhaltung als die maximale Einschubtiefe des Schlüssels 3 begrenzender Anschlag zum Einsatz kommen, insbesondere auch eine entsprechend gestaltete und von unten in den Bereich der Einkerbungen 9 des Schlüssels 3 (Fig. 1) ragende Stiftzuhaltung, deren oberes Ende beispielsweise eine im wesentlichen vertikal zur Längsachse des Schließzylinders 1 verlaufende Anschlagfläche aufweist. As already mentioned, any one can be used instead of the wire element 17 guard locking other than the maximum insertion depth of the key 3 limiting stop are used, especially one accordingly designed and from below in the area of the notches 9 of the key 3 (Fig. 1) protruding pin tumbler, the upper end for example one essentially vertical to the longitudinal axis of the locking cylinder 1 extending stop surface.

Fig. 3 zeigt eine von Fig. 1 verschiedene Ausführungsvariante eines erfindungsgemäß verwendbaren Schlüssels. Dieser Schlüssel gemäß Fig. 3 weist auf einer seiner Breitseiten eine Ausnehmung 22 auf, deren dem Schlüsselkopf 10 zugewandtes Ende 23 das einzige Anschlagelement zur Begrenzung der Einschubtiefe des Schlüssels in einen Schlüsselkanal darstellt. Dieses Anschlagelement 23 ist beabstandet zur Schlüsselspitze 10' angeordnet.FIG. 3 shows an embodiment variant of an embodiment of the invention that differs from FIG. 1 usable key. This key according to FIG. 3 has on one of its broad sides a recess 22, the Key head 10 facing end 23 the only stop element for Limitation of the depth of the key into a key channel represents. This stop element 23 is spaced from the key tip 10 'arranged.

Fig. 3 soll lediglich erläutern, daß die Ausnehmung 22 nicht zwangsläufig am Schlüsselrücken 13, wie in Fig. 1 dargestellt, angeordnet sein muß, sondern daß ohne weiteres auch eine Vorsehung der Ausnehmung 22 im Bereich einer oder beider Breitseiten des Schlüssels möglich ist.Fig. 3 is only intended to explain that the recess 22 is not necessarily must be arranged on the back of the key 13, as shown in FIG. 1, but that a provision of the recess 22 in the Area of one or both broad sides of the key is possible.

Auch bei einem Schlüssel gemäß Fig. 3 kann die Anzahl der möglichen Permutationen dadurch erhöht werden, daß bei unterschiedlichen Schließzylindern das Anschlagelement 23 an unterschiedlichen Positionen bezogen auf die Längsachse des Schließzylinders bzw. des Schlüsselschafts angeordnet wird und/oder indem die Tiefe der Ausnehmung 22 quer zur Längsachse des Schlüsselschafts variiert wird.3, the number of possible Permutations are increased in that at different Lock cylinders the stop element 23 at different positions related to the longitudinal axis of the locking cylinder or key shaft is arranged and / or by the depth of the recess 22nd is varied transversely to the longitudinal axis of the key shaft.

Zudem besteht - wie bereits erwähnt - auch die Möglichkeit, die Ausnehmung 22 im Bereich des Schlüsselbarts, also im Bereich der Einkerbungen 9 vorzusehen. Weiterhin ist es möglich, an einem einzigen Schlüssel mehrere, als Anschlagflächen wirkende Ausnehmungen an unterschiedlichen Positionen des Schlüssels vorzusehen.In addition, as already mentioned, there is also the possibility of the recess 22 in the area of the key bit, ie in the area of the notches 9 to be provided. It is also possible to use a single key several recesses acting as stop surfaces on different To provide positions of the key.

Die Fig. 4a, b zeigen schematische Schnittansichten eines Schließzylinders 1, welcher für einen Schlüssel gemäß Fig. 3 geeignet ist. 4a, b show schematic sectional views of a locking cylinder 1, which is suitable for a key according to FIG. 3.

In Fig. 4a ist ein seitlich, horizontal in den Schließzylinderkern 1' eingebrachter Stift 24 gezeigt, dessen eines stirnseitiges Ende in den Schlüsselkanal 2 des Schließzylinders 1 ragt, so daß dieser Endbereich des Stifts 24 als schließzylinderseitige Anschlagfläche für die auf der Breitseite des Schlüssels gemäß Fig. 3 vorgesehene Anschlagfläche 23 dient. Der Stift 24 stellt somit wiederum ein stationäres Anschlagelement dar, wobei auch durch dieses Anschlagelement wieder die bereits erläuterten Permutationen erreicht werden können, indem der Stift 24 an unterschiedlichen Stellen des Schließzylinders 1 angeordnet wird und/oder indem der Stift 24 bei verschiedenen Schließzylindern verschieden weit in den Schlüsselkanal 2 hineinragt.In Fig. 4a is a laterally, horizontally introduced in the lock cylinder core 1 ' Pin 24 shown, one end end in the key channel 2 of the lock cylinder 1 protrudes so that this end portion of the pin 24 as a locking cylinder-side stop surface for the on the broad side of the 3 provided stop surface 23 is used. The pin 24 thus again represents a stationary stop element, whereby also through this stop element the permutations already explained can be achieved by the pin 24 at different Set the lock cylinder 1 is arranged and / or by the pin 24 with different locking cylinders in the key channel 2 protrudes.

Fig. 4b entspricht im wesentlichen Fig. 4a mit dem Unterschied, daß es sich hier um ein mit einer Zuhaltung zusammenwirkendes Anschlagelement 25 handelt, welches unter der Vorspannung einer Feder 26 steht. Der Stift 25 besitzt auf seiner Unterseite eine Einkerbung, in die bei vollständig eingeschobenem Schlüssel eine Stiftzuhaltung 27 eingreift und in diesem Fall eine Drehbewegung des Zylinderkerns 1' ermöglicht. Durch entsprechend unterschiedliche Anordnungen des Stifts 25 kann auch bei dieser Ausführungsform eine Erhöhung der Permutationsmöglichkeiten erreicht werden. Fig. 4b corresponds essentially to Fig. 4a with the difference that it is a stop element interacting with a tumbler 25 acts, which is under the bias of a spring 26. The pin 25 has a notch on its underside, in the complete inserted key engages a pin tumbler 27 and in this case allows a rotary movement of the cylinder core 1 '. By accordingly different arrangements of the pin 25 can also this embodiment an increase in the permutation possibilities can be achieved.
