Abstract

Lock cylinder comprises a cylinder core (2) rotatably mounted in a housing (1) and having a key channel, and bores (11, 12) protruding from the housing into the key channel. Each bore has a pin pair consisting of a housing pin (10) and a core pin (9) moved by spring force. The insertion depth of at least one core pin into the key channel is reduced relative to the insertion depth of the other core pin by a stop (14). The stop is formed by a gap in the diameter of the bore (11). The bore (12) in the housing and the bore (11) in the cylinder core have a greater diameter up to the gap than the bore continuing (11) in the cylinder core. The housing pin has a diameter corresponding to the housing bore and its displacement path in the cylinder core is limited by the gap.

Description

Die Erfindung betrifft einen Schließzylinder mit einem in einem Gehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal aufweist, und mit Bohrungen, die vom Gehäuse ausgehend bis in den Schlüsselkanal des Zylinderkernes hineinragen, wobei in jeder Bohrung ein durch Federkraft verschiebbares Stiftpaar aus Gehäusestift und Kernstift vorgesehen ist und die Einschubtiefe mindestens eines Kernstiftes in den Schlüsselkanal gegenüber der Einschubtiefe der anderen Kernstifte durch einen Anschlag verkürzt ist.The invention relates to a lock cylinder with a a housing rotatably mounted cylinder core, the one Has key channel, and with holes from the housing protruding into the key channel of the cylinder core, in each bore a spring-loaded A pair of pins consisting of housing pin and core pin are provided and the insertion depth of at least one core pin in the key channel opposite the insertion depth of the others Core pins are shortened by a stop.

Abgesehen von Gewaltanwendungen auf eine Türe oder einen Schließzylinder in einem Türschloss sind Einbruchsmethoden bekannt, bei welchen mit Einbruchswerkzeugen versucht wird, die Kernstifte in die Freigabestellung zu verschieben. Dies ist schon bei einem Schließzylinder mit fünf Stiftpaaren nahezu unmöglich, da bei Erreichen der Teilung eines Stiftpaares die durch eine Vorspannung auf den Kern festgehaltene Positionierung eines anderen Stiftpaares in aller Regel verloren geht. Durch elektrisch oszillierende, langgestreckte schmale zungenförmige Plättchen wie auch durch mechanische Methoden wurde versucht, die Stiftpaare in eine Auf- und Abbewegung zu versetzen. Dabei könnten vermeintlich allenfalls durch Zufall für einen Augenblick alle Stiftpaare gleichzeitig in der Freigabestellung stehen. Wenn in diesem Augenblick ein Drehmoment an dem Zylinderkern anliegt, dann besteht die Möglichkeit, dass der Zylinderkern aus der Sperrstellung weggedreht werden kann.Except for violent use on a door or one Lock cylinders in a door lock are intrusion methods known in which attempts are made with intrusion tools, to move the core pins into the release position. This is almost a lock cylinder with five pairs of pins impossible because when the division of a pair of pins is reached the positioning held in place by a preload on the core of another pair of pins is usually lost goes. By electrically oscillating, elongated narrow tongue-shaped plates as well as by mechanical Methods were attempted to move the pin pairs up and down to move. At the most, supposedly accidentally all pin pairs for a moment stand in the release position. If at that moment there is a torque on the cylinder core, then there is Possibility that the cylinder core turned away from the locked position can be.

Aus der EP 771 920 A1 ist es bekannt, dass zur Erschwernis des Abtastens (DIN 18 252 Punkt 2.10) ein Kernstift in Richtung auf die Teilungsfläche zwischen Zylinderkern und Zylindergehäuse zurückversetzt ist. Dadurch erreicht eine Abtastnadel die Angriffsfläche des betreffenden Kernstiftes nur erschwert. Die zurückversetzte Lage dieses Kernstiftes wird durch eine verkürzte Kernbohrung erreicht.From EP 771 920 A1 it is known that to make it difficult of scanning (DIN 18 252 point 2.10) a core pin in the direction on the dividing surface between the cylinder core and the cylinder housing is set back. This will reach a stylus the attack surface of the core pin concerned only difficult. The set back position of this core pin will achieved by a shortened core drilling.

Aus der DE 633 934 B ist ein Schließzylinder mit sternförmig ausgerichteten Kern- und Gehäusebohrungen und mit einem kreiszylindrischen Schlüsselkanal beschrieben. Die Kernstifte sind als abgesetzte Stifte ausgebildet, sodass der Verschiebungsweg in das Innere des Schlüsselkanals begrenzt ist.From DE 633 934 B a locking cylinder with a star shape aligned core and housing bores and with one circular cylindrical key channel described. The core pins are designed as stepped pins, so that the displacement path is confined to the interior of the key channel.

Die Erfindung zielt darauf ab, der letztgenannten Einbruchsmethode durch bauliche Maßnahmen im Schließzylinder in mehrfacher Weise entgegenzuwirken. Dies wird dadurch erreicht, dass der Anschlag als ein im Zylinderkern liegender Durchmessersprung der Bohrung ausgebildet ist, wobei die Bohrung im Gehäuse und die Bohrung im Zylinderkern bis zum Durchmessersprung hin einen größeren Durchmesser aufweisen, als die sich im Zylinderkern fortsetzende Bohrung und dass der Gehäusestift einen der Gehäusebohrung entsprechenden Durchmesser aufweist und sein Verschiebungsweg in den Zylinderkern hinein durch den Durchmessersprung begrenzt ist. Durch diesen Anschlag kann ein Kernstift gegenüber den anderen mit seiner Angriffsfläche im Schlüsselkanal zurückversetzt werden, wobei die Ausbildung des Anschlages für den Gehäusestift gleichzeitig eine falsche Teilungsfläche vortäuscht. Wenn also der betreffende Kernstift überhaupt erreicht wird und die Freigabestellung der anderen Stiftpaare tatsächlich vorliegen sollte und festgehalten werden kann, dann gelangt das eine Stiftpaar in eine scheinbare Freigabestellung, bei der der Zylinderkern weiterhin gegenüber dem Zylindergehäuse drehfest bleibt.The invention aims at the latter intrusion method through structural measures in the locking cylinder counteract in several ways. This is achieved that the stop as a lying in the cylinder core Diameter jump of the bore is formed, the bore in the housing and the bore in the cylinder core up to Jump in diameter have a larger diameter, than the bore continuing in the cylinder core and that the housing pin corresponds to the housing bore Has diameter and its displacement path in the cylinder core is limited by the jump in diameter. This stop can make one core pin opposite the other set back with its attack surface in the key channel be, the formation of the stop for the housing pin at the same time pretends an incorrect division area. So if the core pin in question reaches it at all and the release position of the other pairs of pins should actually exist and can be recorded, then the one pair of pins comes into an apparent release position, where the cylinder core continues to the Cylinder housing remains non-rotatable.

Alle Gehäusebohrungen können stets mit gleichem Durchmesser und alle Kernbohrungen stets mit geringfügig kleinerem Durchmesser auch bei Schließzylindern ohne der hier in Rede stehenden Sicherheitsebene ausgebildet sein. Die Kernbohrungen können auch durchwegs eine Ansenkung mit Durchmessersprung aufweisen. Wenn Gehäusestifte mit dem üblichen großen Spiel verwendet werden, dann können diese auch in die Kernbohrung eingeschoben werden. Nur bei der Realisierung der Erfindung muss der Gehäusestift der Gehäusebohrung genauer angepasst sein, sodass er am Durchmessersprung im Zylinderkern anschlägt.All housing bores can always have the same diameter and all core holes always with a slightly smaller diameter even with locking cylinders without the one in question Be trained security level. The core holes can also consistently countersink with a jump in diameter exhibit. If housing pins with the usual big game can then be used in the core hole be inserted. Only when realizing the invention the housing pin must be adapted more precisely to the housing bore be so that it stops at the diameter jump in the cylinder core.

Bei der Ausführung gemäß der Erfindung dringt die Kernbohrung tiefer in den Schlüsselkanalquerschnitt hinein, als es der Länge des Kernstiftes entspricht. Damit ist der Kernstift in der Kernbohrung frei beweglich. Die übliche Einbaulage eines Schließzylinders wird vorausgesetzt.In the embodiment according to the invention, the core bore penetrates deeper into the key channel cross-section than it is corresponds to the length of the core pin. This is the core pin freely movable in the core hole. The usual installation position of a Lock cylinder is required.

Um eine reibungsarme Funktion zu gewährleisten ist es zweckmäßig, wenn der Querschnitt der Gehäusestifte einem Polygon, z.B. Achteck, mit einem Umkreisdurchmesser gemäß dem Bohrungsdurchmesser entspricht.It is to ensure a low-friction function useful if the cross-section of the housing pins is a polygon, e.g. Octagon, with a radius according to the Corresponds to the bore diameter.

Dies gilt insbesondere für den Gehäusestift, der in der Gehäusebohrung genauer geführt wird, also ein geringeres Spiel hat. Es ist zudem zu beachten, dass ein sehr exakt geführter Stift in Kreiszylinderform beim Zurückschieben gegen eine meist unerwünschte Luftdämpfung anläuft, wodurch das Einschieben eines Schlüssels in den Schlüsselkanal behindert wird. Dies entfällt bei einem Querschnitt gemäß einem Polygon od. dgl.This applies in particular to the housing pin in the housing bore is performed more precisely, i.e. a less game Has. It should also be noted that a very precisely managed Pin in circular cylinder shape when pushing back against one mostly unwanted air cushioning starts, causing the insertion of a key in the key channel becomes. This does not apply to a cross section according to a polygon or the like

Für den Fall, dass die Einbausituation des Schließzylinders beispielsweise eine kopfüber- Montage erfordert, ist es ferner zweckmäßig, dass das Stiftpaar mit verkürzter Einschubtiefe an der Berührungsstelle zwischen Kern- und Gehäusestift einen magnetischen Kraftschluss, z.B. durch mindestens einen in die Stirnfläche des einen Stiftes eingesetzten Magneten bei ferromagnetischer Ausbildung des anderen Stiftes aufweist.In the event that the installation situation of the locking cylinder for example, requires an upside-down assembly, it is also expedient that the pair of pins with a shorter insertion depth at the point of contact between the core and housing pins a magnetic adhesion, e.g. by at least one in the end face of a magnet inserted a pin with ferromagnetic formation of the other pin.

Ausführungsbeispiele des Erfindungsgegenstandes sind in den Zeichnungen dargestellt. Fig. 1 zeigt einen Querschnitt durch einen Schließzylinder mit einem Schlüssel als illegales Einbruchswerkzeug, Fig. 2 einen Schnitt durch den Berührungsbereich eines Gehäuse- und Kernstiftes in stark vergrößertem Maßstab und Fig. 3 eine Draufsicht auf einen Gehäusestift gemäß Fig. 2.Embodiments of the subject matter of the invention are in the Drawings shown. Fig. 1 shows a cross section through a lock cylinder with a key as an illegal burglary tool, Fig. 2 shows a section through the contact area a housing and core pin in greatly enlarged Scale and Fig. 3 is a plan view of a housing pin according to Fig. 2.

Um einen Schließzylinder sperren zu können, verschiebt ein passender Flachschlüssel die z.B. fünf jeweils aus einem gefederten Gehäusestift und einem Kernstift bestehenden Stiftpaare so, dass alle Berührungsflächen der Kernstifte mit den Gehäusestiften genau in der Mantelfläche des Zylinderkernes zu liegen kommen. Bevor der Flachschlüssel in den Schlüsselkanal eingeführt wird, schieben die Gehäusestifte ihre jeweiligen Kernstifte unter Federkraft bis an das Ende der jeweiligen radialen Kernstiftbohrung im Zylinderkern. Von dieser Sperrstellung ausgehend verschiebt der passende Flachschlüssel die als Zuhaltungen wirkenden Stiftpaare in die individuelle Freigabestellung wie dies oben beschrieben wurde. Fig. 1 zeigt einen Querschnitt durch einen Schließzylinder mit einem Zylindergehäuse 1, in dem ein Zylinderkern 2 drehbar gelagert ist. In Bohrungen 3, 4 im Zylindergehäuse 1 wie auch im Zylinderkern 2 liegen jeweils ein durch eine Feder 5 vorgespannter Gehäusestift 6 und je ein Kernstift 7. Die Linie 8 markiert die Mantelfläche des Zylinderkernes 2 im Schnitt der Fig. 1. Bis genau zu dieser Linie 8 muss ein passender Schlüssel die Berührungsflächen zwischen allen Kernstiften 7 und Gehäusestiften 6 verschieben um so bei erreichter Teilung ein Verdrehen des Zylinderkernes 2 im Zylindergehäuse 1 zu ermöglichen.To be able to lock a locking cylinder, move one suitable flat key which e.g. five each from a sprung Housing pin and a core pin existing pin pairs so that all contact surfaces of the core pins with the Housing pins exactly in the outer surface of the cylinder core come to rest. Before the flat key into the key channel is inserted, the body pins slide their respective Core pins under spring force to the end of each radial core pin bore in the cylinder core. Of this The appropriate flat key moves outward from the locked position the pairs of pins acting as tumblers into the individual Release position as described above. Fig. 1 shows a cross section through a lock cylinder with a Cylinder housing 1 in which a cylinder core 2 is rotatably supported is. In holes 3, 4 in the cylinder housing 1 as well as in the cylinder core 2 are each biased by a spring 5 Housing pin 6 and one core pin 7. Line 8 marks the lateral surface of the cylinder core 2 in the section of the Fig. 1. Up to exactly this line 8 must be a suitable Key the contact surfaces between all core pins 7 and move housing pins 6 so when division is reached a twisting of the cylinder core 2 in the cylinder housing 1 to enable.

In Fig. 1 ist als Besonderheit zu erkennen, dass ein Kernstift 9 von seinem Gehäusestift 10 nicht zur Gänze in die Kernstiftbohrung 11 eingeschoben wird. Gemäß Fig. 2 ist nämlich der Durchmesser der Bohrung 12 im Zylindergehäuse 1 sowie in einem Teil des Zylinderkernes 2 größer als die daran anschließende Kernbohrung 11. In Übereinstimmung mit den Bohrungsdurchmessern hat der Gehäusestift 10 einen größeren Durchmesser als der Kernstift 9. Somit liegt der Gehäusestift 10 an einem Anschlag 14 an, der durch den Durchmessersprung der Kernbohrung 11 gebildet wird. Daraus folgt, dass der Kernstift 9 in der gezeichneten Gebrauchslage des Schließzylinders nach Fig. 1 das Ende seiner Kernstiftbohrung 11 nicht erreicht. Ein als Einbruchswerkzeug vorgesehener Schlüssel 15 weist ein Profil auf, das ein Einschieben in den Schlüsselkanal des Zylinderkernes 2 ermöglicht. Ferner ist dieser Schlüssel 15 mit einer Zahnung 16 ausgestattet, die die Kernstifte 7 nur kontaktieren, also berühren soll. Zweck ist es, dass durch einen Stoß oder eine Oszillation des Schlüssels 15 im Schlüsselkanal gemäß Pfeil 17, Stöße auf die Stiftpaare derart übertragen werden sollen, dass die jeweiligen Berührungsflächen zwischen Gehäusestiften 6 und Kernstiften 7 zumindest bis zur Linie 8 gelangen. Durch ein Drehmoment auf den Zylinderkern 2 soll diese Zufallsstellung genutzt und ein Öffnen des Schließzylinders ermöglicht werden.In Fig. 1 it can be seen as a special feature that a core pin 9 from its housing pin 10 not entirely in the Core pin bore 11 is inserted. 2 is namely the diameter of the bore 12 in the cylinder housing 1 and in a part of the cylinder core 2 larger than that Subsequent core bore 11. In accordance with the bore diameter the housing pin 10 has a larger one Diameter than the core pin 9. The housing pin is thus located 10 at a stop 14 by the diameter jump the core bore 11 is formed. It follows that the Core pin 9 in the drawn position of use of the locking cylinder 1 the end of its core pin bore 11 is not reached. A key 15 provided as a burglary tool has a profile that is inserted into the key channel of the cylinder core 2 enables. Furthermore, this is Key 15 equipped with a toothing 16, the core pins 7 only contact, i.e. should touch. Purpose is that by a shock or an oscillation of the key 15 in the key channel according to arrow 17, hits the pin pairs should be transferred in such a way that the respective contact surfaces between housing pins 6 and core pins 7 at least get to line 8. With a torque the cylinder core 2 should use this random position and a Opening of the lock cylinder are made possible.

Wie Fig. 1 jedoch zeigt, verhindert der Anschlag 14 einen Kontakt des Kernstiftes 9 mit der Zahnung 16 des Schlüssels 15. Der vom Einbrecher gewünschte Effekt der Schwingungsoder Stoßübertragung findet mangels Berührung mit dem Kernstift 9 bei diesem Stiftpaar nicht statt. Dieses Stiftpaar 9, 10 sperrt daher weiterhin und die Teilung wird natürlich nicht erreicht. Zudem täuscht der Anschlag 14 eine Teilungsfläche vor, so wie auch die Vielzahl der Ringnuten in den Gehäusestiften 6.However, as FIG. 1 shows, the stop 14 prevents one Contact of the core pin 9 with the toothing 16 of the key 15. The effect of the vibration or Impact transmission takes place due to lack of contact with the core pin 9 does not take place with this pair of pins. This pair of pins 9, 10 therefore continues to lock and the division becomes natural not reached. In addition, the stop 14 deceives a division area as well as the large number of ring grooves in the housing pins 6th

In der üblichen Einbaulage liegen die gefederten Gehäusestifte 6, 10 unterhalb des Zylinderkernes 2 und die radiale Öffnung des Schlüsselkanals im Zylinderkern 2 weist nach oben. Es gibt aber Einbausituationen, wo der Schließzylinder nicht in der üblichen Einbaulage montiert werden kann, sondern um 180° um die Zylinderlängsachse verdreht eingebaut werden muss. Eine derartige Einbausituation ist gelegentlich bei Zusatzschlössern oder einfachen Zusatzriegeln anzutreffen. In dieser kopfüber-Einbausituation des Schließzylinders fällt der Kernstift 9 ohne Gegenmaßnahmen gravitationsbedingt bis auf den Boden der Kernstiftbohrung 11. Dieser ungewollte Effekt kann verhindert werden, wenn an der Berührungsstelle zwischen dem Kernstift 9 und dem Gehäusestift 10 ein magnetischer Kraftschluss vorgesehen ist. Der magnetische Kraftschluss kann beispielsweise durch Einsetzen eines Magneten in die Stirnfläche des einen Stiftes und ferromagnetischer Ausbildung des gegenüberliegenden Stiftes realisiert werden.
Dadurch klebt gewissermaßen der Kernstift 9 magnetisch am Gehäusestift 10 und wird auf diese Weise in der gewünschten, mit seiner Angriffsfläche zurückversetzten, Lage gehalten.In the usual installation position, the spring-loaded housing pins 6, 10 lie below the cylinder core 2 and the radial opening of the key channel in the cylinder core 2 points upwards. However, there are installation situations where the locking cylinder cannot be installed in the usual installation position, but must be installed rotated by 180 ° around the cylinder's longitudinal axis. Such an installation situation is occasionally encountered with additional locks or simple additional bolts. In this installation situation of the locking cylinder upside down, the core pin 9 falls due to gravity to the bottom of the core pin bore 11 without countermeasures. This unwanted effect can be prevented if a magnetic force connection is provided at the point of contact between the core pin 9 and the housing pin 10. The magnetic frictional connection can be realized, for example, by inserting a magnet into the end face of one pin and ferromagnetic formation of the opposite pin.
As a result, the core pin 9, as it were, sticks magnetically to the housing pin 10 and is thus held in the desired position, set back with its contact surface.

Gemäß Fig. 3 hat der Gehäusestift 10 eine von der Kreisform abweichende Querschnittsform, sodass es zu einer Linienberührung und damit zu besseren Gleiteigenschaften in der Gehäusebohrung 12 kommt. Dies gilt sinngemäß auch für alle anderen Stifte.3, the housing pin 10 has a circular shape deviating cross-sectional shape, so that there is a line contact and thus for better sliding properties in the housing bore 12 is coming. This also applies to everyone else Pencils.
