Description

Die Erfindung betrifft ein Zylinderschloss mit zumindest einem Zylinderkern, der in der Zylinderkernbohrung des Zylindergehäuses drehbar angeordnet ist, wobei Zylinderkern und Zylindergehäuse Stiftbohrungen aufweisen, die jeweils aus Kernstiftbohrungen und Gehäusestiftbohrungen bestehen, die miteinander fluchten, wenn der Zylinderkern in unverdrehter Stellung steht und wobei in den Stiftbohrungen je ein Gehäusestift und ein Kernstift verschiebbar gelagert sind.The invention relates to a cylinder lock with at least one cylinder core in the cylinder core bore of the cylinder housing is rotatably arranged, wherein cylinder core and cylinder housings have pin bores, each of core pin bores and housing pin holes exist that are aligned with each other when the Cylinder core is in the untwisted position and wherein in the pin holes one each Housing pin and a core pin are slidably mounted.

Solche Zylinderschlösser sind seit langer Zeit Stand der Technik. Ebenfalls seit langer Zeit haben sich verschiedene Nachsperrmethoden unter Verwendung spezieller Nachsperrwerkzeuge herausgebildet, die zur missbräuchlichen Öffnung von Zylinderschlössern verwendet werden können.Such cylinder locks are state of the art for a long time. Also for a long time Time has become different Nachsperrmethoden using special Nachsperrwerkzeuge formed, which is used for the improper opening of cylinder locks can be used.

Neuerdings ist eine Nachsperrmethode bekannt geworden, bei der ein sogenannter Adapterschlüssel Verwendung findet. Dieser Schlüssel passt im Rückenbereich des Schlüsselkanals in den Schlüsselkanal hinein und besitzt einen Bart mit einer Reihe aufeinanderfolgender Zacken für die zugehörigen Kernstifte des Zylinderkerns. Wenn der Adapterschlüssel und damit der Zylinderkern mit einer leichten Drehbewegung unter Drehspannung gesetzt wird, genügt ein Schlag auf den Schlüssel in Richtung der Achse des Zylinderkerns, um das Zylinderschloss zu öffnen. Die Wirkung des Werkzeuges ergibt sich daraus, dass durch die Zacken des Adapterschlüssels die Stiftzuhaltungen insgesamt eine starke Beschleunigung gegen die Stiftfedern erfahren. Dadurch kommt es zu einer Prellbewegung zwischen den Kernstiften und den zugehörigen Gehäusestiften, wodurch sich diese kurzzeitig auseinander bewegen und durch den Drehdruck des Zylinderkerns der Zylinderkern deswegen freigegeben wird, weil keiner der Kernstifte oder Gehäusestifte die Fläche der Zylinderkernbohrung durchragt. Recently, a Nachsperrmethode has become known in which a so-called Adapter key is used. This key fits in the back area of the Key channel into the key channel and has a beard with a row successive prongs for the associated core pins of the cylinder core. If the adapter key and thus the cylinder core with a slight rotational movement is set under torsional stress, a stroke on the key in the direction is sufficient the axis of the cylinder core to open the cylinder lock. The effect of Tool results from the fact that the teeth of the adapter key the Pen tumblers experience overall a strong acceleration against the pen feathers. This results in a bouncing movement between the core pins and the associated housing pins, causing them to move apart for a short time and therefore released by the rotational pressure of the cylinder core of the cylinder core is because none of the core pins or housing pins the surface of the cylinder core bore projects through.

Aufgabe der vorliegenden Erfindung ist es, die Aufsperrsicherheit des Zylinderschlosses zu erhöhen und insbesondere die genannte Nachsperrmethode zu erschweren oder zu verhindern.Object of the present invention is the Aufsperrsicherheit the cylinder lock and in particular to complicate the said Nachsperrmethode or to prevent.

Das in Fig. 1 dargestellte Zylinderschloss ist ein Doppelzylinder, der zwei Zylinderkerne aufweist, die wechselseitig von beiden Seiten das Schloss sperren können. Die erfindungsgemäße Ausgestaltung kann sowohl an einem Zylinderkern als auch an beiden Zylinderkernen vorgesehen sein. Es sind nur die zur vorliegenden Erfindung wesentlichen Bestandteile des Zylinderschlosses dargestellt.The cylinder lock shown in Fig. 1 is a double cylinder, the two cylinder cores which can mutually lock the lock from both sides. The inventive design can both on a cylinder core and on be provided with two cylinder cores. It is only those of the present invention essential components of the cylinder lock shown.

Der Zylinderkern 1 ist in der Zylinderkernbohrung 2 des Zylindergehäuses 3 drehbar angeordnet. In den Schlüsselkanal 16 kann der zugehörige Schlüssel in den Zylinderkern eingesteckt werden, sodass in bekannter Weise die Kernstifte 17 und die zugehörigen Gehäusestifte, die allgemein mit dem Bezugszeichen 18 bezeichnet sind, in eine solche Lage gebracht werden, dass die Teilungen 19 zwischen Kernstift und Gehäusestift in der Drehebene der Zylinderkernbohrung 2 liegen und somit die Drehung des Zylinderkerns erlauben. Die Stiftfedern 20 spannen die aus den Gehäusesfiften 18 und Kernstiften 17 bestehenden Stiftzuhaltungen nach oben in Richtung zum Schlüsselkanal 16.The cylinder core 1 is rotatable in the cylinder core bore 2 of the cylinder housing 3 arranged. In the keyway 16, the associated key in the cylinder core be inserted, so that in a known manner, the core pins 17 and the associated housing pins, generally designated by the reference numeral 18 are to be placed in such a position that the divisions 19 between Kernstift and housing pin lie in the plane of rotation of the cylinder core bore 2 and thus the Allow rotation of the cylinder core. The pen springs 20 clamp the out of the Gehäusfiften 18 and core pins 17 existing pin tumblers upward toward to the key channel 16.

Gemäß vorliegender Erfindung sind die Gehäusestifte 18 und die Zylinderkernbohrung 2 oder alternativ der Zylinderkern 1 im Bereich der Mündung 11 der Gehäusestiftbohrungen besonders ausgestaltet.According to the present invention, the housing pins 18 and the cylinder core bore 2 or alternatively the cylinder core 1 in the region of the mouth 11 of the housing pin holes specially designed.

Die Figuren 2 und 3 zeigen zwei Ausführungsbeispiele, die entweder alleine oder auch in Kombination in einem Zylinder vorgesehen werden können. In Fig. 1 sind insgesamt 3 Ausführungsvarianten des Gehäusestiftes eingezeichnet.Figures 2 and 3 show two embodiments, either alone or can also be provided in combination in a cylinder. In Fig. 1 are a total of 3 embodiments of the housing pin located.

Fig. 2a und 3a zeigt zwei Varianten in Freigabestellung der Stiftzuhaltung, die eingenommen wird, wenn ein richtiger Schlüssel eingeschoben ist und der Zylinderkern verdreht werden kann.Fig. 2a and 3a shows two variants in the release position of the pin tumbler, which taken is when a correct key is inserted and the cylinder core can be twisted.

In Fig. 2b und Fig. 3b ist jene Funktionsstellung eingezeichnet, bei der missbräuchlich durch ein Nachsperrwerkzeug der Zylinderkern 1 leicht verdreht wird, wobei sich die Gehäusestifte 6 und 7 durch den Druck der Stiftfedern 20 in die Kernstiftbohrung hinein erstrecken, sodass ein Weiterdrehen des Zylinderkerns unmöglich ist.In Fig. 2b and Fig. 3b that functional position is shown, in the abusive is slightly rotated by a Nachsperrwerkzeug the cylinder core 1, wherein the housing pins 6 and 7 by the pressure of the pin springs 20 in the core pin hole extend into it, so that further rotation of the cylinder core is impossible.

Wie weiter unten noch genauer erklärt wird, sind die Gehäusestifte mit ihren Achsen gegenüber den Achsen der Gehäusestiftbohrungen kippbar oder im Kopfabschnitt verschiebbar. Im Ausführungsbeipiel Fig. 2 besteht der Gehäusestift aus einer Schraubfeder, wie sie in Fig. 6 vergrößert dargestellt ist. Bei dieser Ausführungsvariante ist somit ein Abschnitt des als Schraubfeder ausgebildeten Gehäusestiftes gegenüber der Achse der Gehäusestiftbohrung seitlich verschiebbar, wie dies in Fig. 2b dargestellt ist. In Fig. 6 ist der Kopfabschnitt mit dem Bezugszeichen 21 angedeutet.As will be explained in more detail below, the housing pins with their axes tiltable with respect to the axes of the housing pin bores or in the head section displaceable. In the Ausführungsbeipiel Fig. 2, the housing pin consists of a Screw spring, as shown enlarged in Fig. 6. In this embodiment is thus a section of the housing pin designed as a helical spring the axis of the housing pin bore laterally displaceable, as shown in Fig. 2b is shown. In Fig. 6 the head portion is indicated by the reference numeral 21.

In der Variante Fig. 3 ist der Gehäusestift als Taumelstift 7 ausgebildet, wie dies an sich bekannt ist. In der Funktionsstellung nach Fig. 3b greift der Pilzkopf des Taumelstiftes über die Mündung der Gehäusestiftbohrung, wie vergrößert in Fig. 5 dargestellt ist. In the variant of Fig. 3, the housing pin is designed as a wobble pin 7, as on is known. In the functional position according to FIG. 3b, the mushroom head of the wobble pin engages over the mouth of the housing pin bore, as enlarged in Fig. 5 shown is.

Als weitere Maßnahme ist in der Zylinderkernbohrung 2 seitlich der Mündung 11 der Gehäusestiftbohrung im Zylindergehäuse eine Freistellausnehmung 12 vorgesehen, um Platz für den Eingriff des Gehäusestiftabschnittes zu bieten, der in die Kernstiftbohrung hineinsteht. Bei dieser Anordnung ist es gemäß Erfindung unmöglich, bei der Stellung nach den Fig. 2b und 3b die eingangs geschilderte Nachsperrmethode durchzuführen. Da die Gehäusestifte in den dargestellten Stellungen in ihrer axialen Beweglichkeit gehindert sind, ist es unmöglich, den Prellvorgang beim Nachsperren herbeizuführen, der bewirken sollte, dass sich Gehäusestift und Kernstift von einander so entfernen, dass die Drehebene der Zylinderkernbohrung freigegeben wird.As a further measure is in the cylinder core bore 2 side of the mouth 11 of the Housing pin bore in the cylinder housing a Freistellausnehmung 12 is provided to provide space for the engagement of the housing pin section, into the core pin hole into stands. In this arrangement, it is impossible according to the invention, in the position shown in FIGS. 2b and 3b, the Nachsperrmethode described above perform. Since the housing pins in the illustrated positions in their axial Agility are hindered, it is impossible to bounce the locking process cause that should cause the housing pin and core pin from each other remove so that the plane of rotation of the cylinder core bore is released.

In den Fig. 4 und 5 sind die einzelnen Merkmale vergrößert dargestellt und die Funktionsweise kann anhand des dargestellten Taumelstiftes besser erläutert werden.In Figs. 4 and 5, the individual features are shown enlarged and the operation can be better explained by the illustrated wobble pin.

Der Zylinderkern 1 sitzt in der Zylinderkernbohrung 2 des Zylindergehäuses 3. In der Kernstiftbohrung 4 sitzt der Kernstift 17 und ist in dieser verschiebbar. Mit der Kernstiftbohrung 4 fluchtet die Gehäusestiftbohrung 5, in der der Gehäusestift 7 als Taumelstift verschiebbar angeordnet ist. Die Vorspannung der Stiftzuhaltung erfolgt durch die Stiftfeder 20.The cylinder core 1 is seated in the cylinder core bore 2 of the cylinder housing 3. In the Kernstiftbohrung 4 sits the core pin 17 and is slidable in this. With the core pin hole 4 is aligned with the housing pin bore 5, in which the housing pin 7 as a wobble pin slidably arranged. The bias of Stiftzuhaltung takes place through the pin spring 20.

An der Mündung 10 der Gehäusestiftbohrung ist beidseitig eine Rastausnehmung 12 in der Zylinderkernbohrung des Zylindergehäuses vorgesehen. Der Gehäusestift 7 umfasst einen Pilzkopf 13 und den Pilzstift 14, die Achse 9 des Gehäusestiftes fluchtet mit der Achse 10 der Gehäusestiftbohrung.At the mouth 10 of the housing pin bore is a latching recess 12 on both sides provided in the cylinder core bore of the cylinder housing. The housing pin 7 comprises a mushroom head 13 and the mushroom pin 14, the axis 9 of the housing pin is aligned with the axis 10 of the housing pin bore.

In Fig. 4 ist der besseren Darstellung halber der Kernstift 17 in einer Lage eingezeichnet, in der er das Verdrehen des Zylinderkerns gestattet, wobei der Gehäusestift 7 nach unten verschoben eingezeichnet ist. Wenn kein Schlüssel oder lediglich ein Nachsperrwerkzeug der eingangs genannten Art eingeschoben ist, wären Kernstift und Gehäusestift gemeinsam nach oben durch den Druck der Stiftfeder 20 verschoben, sodass der Gehäusestift 7 teilweise in die Kernstiftbohrung 4 hineinragt, wodurch der Zylinderkern nicht verdreht werden kann.4, the core pin 17 is drawn in a position for better illustration, in which he allows the twisting of the cylinder core, wherein the housing pin 7 is shown shifted down. If no key or just one Post locking tool of the type mentioned is inserted core pin and housing pin moved together upward by the pressure of the pin spring 20, so that the housing pin 7 partially protrudes into the core pin hole 4, whereby The cylinder core can not be twisted.

Fig. 5 zeigt die Funktionsstellung, die zur Verhinderung des unberechtigten Nachsperrens eingenommen wird, nachdem der Zylinderkern mit dem Adapterschlüssel leicht in Drehung gehalten und ein Schlag auf den Adapterschlüssel ausgeführt wird. Fig. 5 shows the functional position, which prevents the unauthorized Nachsperrens is taken after the cylinder core with the adapter key slightly twisted and a strike is made on the adapter key.

Durch den Prellvorgang kann der Gehäusestift 7 höchstens bis zur dargestellten Lage gebracht werden, in der der Pilzkopf 13 in die Freistellausnehmung 12 eingreift und dort sicher festgehalten wird. Ein Verdrehen des Zylinderkernes ist dabei unmöglich.By the bouncing process, the housing pin 7 at most up to the position shown are brought, in which the mushroom head 13 engages in the recess recess 12 and is held there securely. A twisting of the cylinder core is impossible.

Wird als Gehäusestift eine Schraubfeder gemäß Fig. 6 verwendet, entsteht eine Funktionsstellung wie sie in Fig. 2b eingezeichnet ist. Dabei verschiebt sich die Achse des Gehäusestiftes in einem Abschnitt 21 der Schraubfeder gegenüber der Achse der Gehäusestiftbohrung.If a helical spring according to FIG. 6 is used as the housing pin, this creates a Functional position as shown in Fig. 2b. The axis shifts the housing pin in a portion 21 of the helical spring relative to the axis the housing pin hole.

Diese beiden Ausführungsvarianten mit Taumelstift und Schraubfeder als Gehäusestifte können in Kombination in einem Zylinderkern vorgesehen werden.These two variants with wobble pin and coil spring as housing pins can be provided in combination in a cylinder core.

Die Anordnung der Freistellausnehmung 12 bietet eine genügend große Auflagefläche für den verschobenen Teil des federartigen Gehäusestiftes oder des Pilzkopfes, sodass es auch bei mehrmaliger Anwendung der Nachsperrmethode nicht zu einer Abnützung der Mündung der Gehäusestiftbohrung kommt, wie dies der Fall wäre, wenn eine solche Ausnehmung nicht vorgesehen wird. Bevorzugt wird bei der Herstellung die Freistellausnehmung 12 als eine durchgehend geräumte Nut vorgesehen, die über die gesamte Länge des Zylindergehäuses verläuft.The arrangement of the Freistellausnehmung 12 provides a sufficiently large contact surface for the displaced part of the spring-like housing pin or the mushroom head, so that even with repeated use of the Nachsperrmethode not to a Wear of the mouth of the housing pin bore comes as would be the case if such a recess is not provided. Preference is given in the production the cutout recess 12 is provided as a continuous cleared groove, which runs over the entire length of the cylinder housing.

Fig. 1 zeigt noch eine dritte Variante des Gehäusestiftes 8 mit Pilzkopf, Pilzstift und einer Schraubfeder, die um den Pilzstift anschliessend an den Pilzkopf angeordnet ist. Auch diese Variante hat die erfindungsgemäße Wirkung.Fig. 1 shows a third variant of the housing pin 8 with mushroom, mushroom and a helical spring, which is arranged around the mushroom pin then to the mushroom head is. This variant also has the effect according to the invention.

Die Fig. 8 zeigt eine weitere bevorzugte Ausgestaltung der Erfindung, wobei im linken Schliesszylinder eines Doppelzylinderschlosses der eingangs erwähnte Adapterschlüssel in jener Position eingezeichnet ist, in der er vor dem Einschlagen zum mißbräuchlichen Öffnen des Schlosses steht. Durch die Zacken des Schlüsselbarts werden die Zuhaltungsstifte zwangsweise nach unten geschleudert, wodurch es zu dem Auseinander-Prellen der Kernstifte und Gehäusestifte kommen kann.Fig. 8 shows a further preferred embodiment of the invention, wherein in the left Lock cylinder of a double cylinder lock of the aforementioned adapter key in that position, in which he before the impact to the Abusive opening of the lock is. Through the teeth of the key bit The tumbler pins are forcibly thrown down, causing it to can come apart the bouncing of the core pins and housing pins.

Die von der Stirnseite des Zylinderkerns 1 gesehen ersten und dritten Stiftzuhaltungen weisen Gehäusestifte 22 auf, die jeweils einen zapfenförmigen Kopfabschnitt aufweisen, der jeweils mit einem Kopfring 24 versehen ist. Die übrigen Zuhaltungsstifte sind als Taumelstifte oder als Schraubfedern ausgebildet, wie dies zuvor beschrieben wurde. Die Aufeinanderfolge der verschiedenen Arten von Gehäusestiften ist nur beispielsweise dargestellt und kann beliebig gewählt werden. Es ist vorteilhaft, wenigstens zwei verschiedene Ausführungen Gehäusestifte vorzusehen.The seen from the front side of the cylinder core 1 first and third pin tumblers have housing pins 22, each having a peg-shaped head portion have, which is each provided with a head ring 24. The remaining tumbler pins are designed as wobble pins or as helical springs, as described above has been. The succession of different types of housing pins is only shown as an example and can be chosen arbitrarily. It is advantageous to provide at least two different types of housing pins.

Die Funktionsweise der Gehäusestifte 22 wird nachfolgend anhand der Figuren 9, 10 und 11 erklärt.The mode of operation of the housing pins 22 will be described below with reference to FIGS. 9, 10 and 11 explains.

Die Fig. 9 zeigt die Ruhestellung, wie sie auch in Fig. 8 eingezeichnet ist. In Fig. 10 sieht man, wie durch den Schlag auf den Adapterschlüssel der Gehäusestift 22 nach unten geprellt wird und durch die leichte Verdrehung des Zylinderkerns 1 der Kopfabschnitt 23 des Gehäusestiftes im Zylinderkern hängen bleibt, sodass er außer Eingriff mit dem zapfenförmigen Kopfabschnitt 23 gelangt. Zu beiden Seiten der Kernstiftbohrung befindet sich eine Freistellausnehmung 21 im Kern. Nach weiterem Verdrehen des Zylinderkerns kommt der Kopfabschnitt 23 des Gehäusestiftes in Eingriff mit der Freistellausnehmung 21 im Kern und der Kopfring 24 wird durch die Kernstiftbohrung 4 mitgenommen. Dadurch kann sich eine Stellung ergeben, wie sie in Fig. 11 eingezeichnet ist. In dieser Stellung ist der Zylinderkern gefangen und das Schloss kann nicht weiter verdreht werden. Damit ist ein Schliessvorgang für das Schloss unmöglich gemacht und die mißbräuchliche Anwendung des Adapterschlüssels ist sofort erkennbar, weil zum einen das Schloss unbrauchbar ist und zum anderen auch der Adapterschlüssel im Schliesskanal gefangen sein kann.Fig. 9 shows the rest position, as shown in Fig. 8. In Fig. 10 one sees, as by the impact on the adapter key of the housing pin 22 after bumped down and by the slight rotation of the cylinder core 1 of the head section 23 of the housing pin gets stuck in the cylinder core, so it disengages with the peg-shaped head portion 23 passes. On both sides of the core pin hole there is a Freistellausnehmung 21 in the core. After further twisting of the cylinder core, the head portion 23 of the housing pin comes into engagement with the Freistellausnehmung 21 in the core and the head ring 24 is through the core pin hole 4 taken. This may result in a position as shown in Fig. 11 is. In this position, the cylinder core is trapped and the lock can not be twisted further. Thus, a closing process for the castle is impossible made and the abusive application of the adapter key is immediate recognizable, because on the one hand the lock is useless and on the other hand also the Adapter key may be caught in the closing channel.

Die Fig. 12 zeigt eine bevorzugte Ausführungsform des Zylinderkerns, wobei zu beiden Seiten aller Kernstiftbohrungen 4 die Freistellausnehmung 21 im Kern vorgesehen ist. Es können also alle Gehäusestifte gemäß dem Gehäusestift 22 mit Kopfabschnitt vorgesehen werden, oder auch nur einige davon in Kombination mit anderen zuvor geoffenbarten Gehäusestiftarten. Die Kernstifte sind durchwegs ungeteilt dargestellt Für Schliessanlagen können die Kernstifte in bekannter Weise auch geteilt vorgesehen werden.Fig. 12 shows a preferred embodiment of the cylinder core, wherein to both Pages all Kernstiftbohrungen 4 the Freistellausnehmung 21 provided in the core is. It can therefore all housing pins according to the housing pin 22 with head section be provided, or just a few in combination with others previously disclosed case types. The core pins are shown throughout undivided For locking systems, the core pins can also be divided in a known manner be provided.

Fig. 13 zeigt einen Schnitt analog der Fig. 5, wobei der Gehäusestift als Taumelstift 7 ausgebildet ist. Im Unterschied zu jenem der Fig. 5 ist er jedoch zweiteilig ausgeführt, wobei die beiden Teile (26, 27) teleskopartig ineinander und auseinander schiebbar sind. Bei dieser Ausführungsart kommt es beim Schlag auf den Adapterschlüssel de facto zu einer Verlängerung des Gehäusestiftes und der obere Pilzkopf hängt sich in die Freistellausnehmung 12 ein. Auch dadurch ist das mißbräuchliche Verdrehen des Zylinderkerns verhindert.Fig. 13 shows a section analogous to FIG. 5, wherein the housing pin as a wobble pin. 7 is trained. In contrast to that of FIG. 5, however, it is designed in two parts, the two parts (26, 27) being telescopically slidable into and out of one another are. In this embodiment, it comes to the impact on the adapter key de facto to an extension of the housing pin and the upper mushroom head hangs in the Freistellausnehmung 12 a. Also by this is the abusive twisting of the Cylinder core prevented.
