Description

Die Erfindung betrifft einen Schließzylinder mit einem in einem Gehäuse bewegbaren Kern mit einem im Kern angeordneten Schließkanal zur Einführung eines Schlüssels mit mehreren Stiftzuhaltungen, wobei die Stiftzuhaltungen jeweils einen im Kern bis in den Schließkanal geführten Kernstift, einen im Gehäuse geführten Gehäusestift und ein Federelement zur Vorspannung des Gehäusestiftes gegen den Kernstift aufweisen, mit einer Nebenzuhaltung und mit einem im Kern angeordneten, bis in den Schließkanal geführten Steuerstift der Nebenzuhaltung und mit einer im Kern angeordneten, von dem Steuerstift wahlweise versperrbaren oder freigebbaren Fangtasche für den Gehäusestift der Stiftzuhaltung.The invention relates to a lock cylinder with a movable core in a housing with a core arranged in the closing channel for introducing a key with several Stiftzuhaltungen, wherein the Stiftzuhaltungen each one guided in the core into the closing channel core pin, guided in the housing housing pin and a spring element for bias having the housing pin against the core pin, with a Nebenzuhaltung and arranged in the core, run into the lock channel control pin Nebenzuhaltung and arranged in the core, from the control pin selectively lockable or releasable catch pocket for the housing pin pin tumbler.

Ein solcher Schließzylinder ist beispielsweise aus der DE 29 10 886 A1 bekannt. Bei diesem Schließzylinder sind mehrere Nebenzuhaltungen in dem Kern angeordnet. Steuerstifte der Nebenzuhaltungen sind bei in den Schließkanal eingeführten, zum Schließen berechtigten Schlüsseln zwischen dem Schlüssel und einer äußeren Begrenzung des Kerns gehalten. Die Steuerstifte verdecken, abgestützt von dem zum Schließen berechtigten Schlüssel, eine die Fangtasche begrenzende Kante des Kerns. Wird der Kern verdreht, gleitet ein Gehäusestift einer der Stiftzuhaltungen über die Steuerstifte. Der Kern lässt sich damit gegenüber dem Gehäuse verdrehen. Werden mit einem nicht zum Schließen berechtigten Schlüssel oder mittels eines Pickingwerkzeuges die Stiftzuhaltungen betätigt, lässt sich der Kern zunächst drehen, bis einer der Gehäusekerne in die Fangtasche eindringt und an der Kante der Nebenzuhaltung anstößt. Nachteilig bei dem bekannten Schließzylinder ist jedoch, dass die Kante einer gewaltsamen Weiterbewegung des Kerns nur einen geringen Widerstand entgegensetzt.Such a lock cylinder is for example from the DE 29 10 886 A1 known. In this lock cylinder several Nebenzuhaltungen are arranged in the core. Control pins of the Nebenzuhaltungen are held in introduced into the lock channel, for closing authorized keys between the key and an outer boundary of the core. The control pins hide, supported by the authorized to close the key, a catch bag edge bounding the core. When the core is twisted, a housing pin of one of the pin tumblers slides over the control pins. The core can thus be rotated relative to the housing. If the pin tumblers are actuated with a key that is not authorized to close or by means of a picking tool, the core can first be rotated until one of the housing cores is turned penetrates into the catch bag and abuts on the edge of the Nebenzuhaltung. A disadvantage of the known lock cylinder, however, is that the edge of a violent further movement of the core opposes only a low resistance.

Der Erfindung liegt das Problem zugrunde, einen Schließzylinder der eingangs genannten Art so weiter zu bilden, dass er einem Entriegelungsversuch einen hohen Widerstand entgegensetzt.The invention is based on the problem to form a lock cylinder of the type mentioned so on that it opposes a Entriegelungsversuch high resistance.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Steuerstift der Nebenzuhaltung an der dem Gehäuse zugewandten Seite die Breite zur Abstützung zumindest zweier Gehäusestifte der Stiftzuhaltungen hat und dass der Steuerstift in einer Freigabestellung die Fangtasche für die Gehäusestifte der Stiftzuhaltungen versperrt und in einer Blockierstellung die Fangtasche zur Aufnahme der Gehäusestifte der zumindest zwei Stiftzuhaltungen freigibt.This problem is solved according to the invention in that the control pin of the secondary tumbler on the side facing the housing has the width for supporting at least two housing pins of the tumbler tumblers and the control pin blocks the catching pocket for the housing pins of the tumbler tumblers in a release position and locks the catching pouch in a blocking position Recording the housing pins of at least two pin tumblers releases.

Durch diese Gestaltung erfolgt die Sperrung des Schließzylinders mittels der Nebenzuhaltung über zumindest zwei der Stiftzuhaltungen. Bei einem Entriegelungsversuch mit einem unberechtigten Schlüssel oder nach der Pickingmethode lässt sich der Kern zunächst gegenüber dem Gehäuse bewegen, bis die Fangtasche des Kerns in die Position der Stiftzuhaltungen gelangt. Wenn der Steuerstift der Nebenzuhaltung nicht durch den Schlüssel in der vorgesehenen Position gehalten, ist tauchen die Gehäusestifte der beiden Stiftzuhaltungen in die Fangtasche des Kerns ein. Anschließend ist die weitere Bewegung des Kerns blockiert. Weil hierbei zwei oder mehrere Stiftzuhaltungen gleichzeitig sperren, wird ein großes Widerstandsmoment gegen eine weitere Bewegung des Flügels erreicht. Daher kann auch bei einem geringen Hub des Steuerstiftes und einer damit verbundenen geringen Eintauchtiefe der Gehäusestifte eine ausreichende Sperrwirkung erreicht werden.By this design, the blocking of the lock cylinder by means of Nebenzuhaltung via at least two of the pin tumblers. In an unlocking attempt with an unauthorized key or by the picking method, the core can first move relative to the housing until the catch pocket of the core reaches the position of the pin tumblers. If the control pin of the secondary tumbler is not held by the key in the intended position, the housing pins of the two pin tumblers will dip into the catch pocket of the core. Subsequently, the further movement of the core is blocked. Because this lock two or more pin tumblers at the same time, a large moment of resistance against further movement of the wing is achieved. Therefore, even with a small stroke of the control pin and a associated with low immersion depth of the housing pins sufficient blocking effect can be achieved.

Eine Schwächung des Kerns durch die Nebenzuhaltung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn der Steuerstift einen Schaft und einen im Verhältnis zu dem Schaft breiten Kopf hat und wenn der Kopf in die Fangtasche hineinragt. Vorzugsweise ist der Schaft zu dem Kopf symmetrisch angeordnet.A weakening of the core by the Nebenzuhaltung can be easily avoided according to another advantageous embodiment of the invention, when the control pin has a shaft and a wide in relation to the shaft head and when the head protrudes into the catch pocket. Preferably, the shaft is arranged symmetrically to the head.

Die Fangtasche und der Steuerstift gestalten sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kompakt, wenn die Fangtasche und der Kopf des Steuerstiftes lang gestreckt gestaltet sind und parallel zur Achse des Kerns ausgerichtet sind.The catch pocket and the control pin are particularly compact according to another advantageous embodiment of the invention, when the catch pocket and the head of the control pin are designed elongated long and are aligned parallel to the axis of the core.

Fehlfunktionen der Nebenzuhaltung lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung weitgehend vermeiden, wenn der Kopf des Steuerstiftes Stützflächen zur Abstützung an Seitenflächen der Fangtasche hat. Hierdurch hat der Steuerstift eine Verdrehsicherung, wodurch die Reproduzierbarkeit der Bewegungen des Steuerstiftes sicherstellt wird. Weiterhin wird hierdurch die Position einer dem Schlüssel zugewandten Spitze des Steuerstiftes festgelegt, so dass ein Entriegeln des Schließzylinders bei berechtigtem Schlüssel zuverlässig gewährleistet ist.Malfunction of Nebenzuhaltung can be largely avoided according to another advantageous embodiment of the invention, when the head of the control pin has support surfaces for support on side surfaces of the catch bag. As a result, the control pin has a rotation, whereby the reproducibility of the movements of the control pin is ensured. Furthermore, this determines the position of a key facing the tip of the control pin, so that unlocking of the lock cylinder is reliably guaranteed with authorized key.

Der Schließzylinder lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders komfortabel betätigen, wenn der Kopf auf seiner dem Schaft abgewandten Seite eine dem Kern entsprechende Drehkontur aufweist. Durch diese Gestaltung werden axiale Bewegungen der Gehäusestifte beim Vorbeibewegen des von einem berechtigten Schlüssel gehaltenen Steuerstiftes vermieden. Die Form des Kopfes lässt sich mittels eines Formfräsers einfach erzeugen.The lock cylinder can be actuated in accordance with another advantageous embodiment of the invention particularly comfortable when the head has on its side facing away from the shaft a core corresponding rotation contour. By this design, axial movements of the housing pins are avoided when passing the held by a legitimate key control pin. The shape of the head can be easily generated by means of a form cutter.

Der Schließzylinder bietet gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen besonders hohen Schutz gegen ein unberechtigtes Entriegeln, wenn der Schaft des Steuerstiftes auf eine Drehachse des Kerns gerichtet ist. Die Fangtasche ist hierdurch auf der Außenkontur symmetrisch gestaltet und stützt damit in beiden Drehrichtungen des Kerns gleich hohe Widerstandsmomente ab.The lock cylinder provides according to another advantageous embodiment of the invention, a particularly high level of protection against unauthorized unlocking when the shaft of the control pin is directed to a rotational axis of the core. The catch pocket is thereby designed symmetrically on the outer contour and thus supports the same high resistance moments in both directions of rotation of the core.

Der Bauraum im Schließzylinder lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach ausnutzen, wenn der Schaft des Steuerstiftes zu den Stiftzuhaltungen im spitzen und/oder stumpfen Winkel ist. Damit lassen sich auf dem Umfang des Kerns bis zu vier Nebenzuhaltungen anordnen. Hierdurch wird zudem die Abfrage der Kontur oder eines Zusatzelementes des Schlüssels vereinfacht.The space in the lock cylinder can be easily exploited according to another advantageous embodiment of the invention, when the shaft of the control pin to the pin tumblers in the acute and / or obtuse angle. This can be arranged on the circumference of the core up to four Nebenzuhaltungen. This also simplifies the query of the contour or an additional element of the key.

Eine Ausnehmung zur Führung des Steuerstiftes der Nebenzuhaltung könnte beispielsweise teilweise im Kern und teilweise im Gehäuse angeordnet sein. Ein zum Schließen unberechtigter Schlüssel würde den Stift der Nebenzuhaltung teilweise in das Gehäuse drücken und die Bewegung des Kerns blockieren. Solche teilweise im Gehäuse angeordneten Ausnehmungen für den Steuerstift vermögen jedoch nur geringe Widerstandsmomente zu übertragen, weil der Hub des Steuerstiftes sehr klein ist. Weiterhin kann sich der Steuerstift auch bei zum Schließen berechtigtem Schlüssel verhaken, was zu einer Verringerung des Komforts beim Schließen des Schließzylinders führt. Der Schließzylinder lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders komfortabel schließen, wenn der Steuerstift der Nebenzuhaltung in jeder Stellung des Kerns ausschließlich innerhalb des Kerns angeordnet ist.A recess for guiding the control pin of the Nebenzuhaltung could for example be arranged partially in the core and partially in the housing. An unauthorized key to close would partially push the pin of the secondary tumbler into the housing and block the movement of the core. However, such partially arranged in the housing recesses for the control pin are able to transmit only small resistance moments, because the stroke of the control pin is very small. Furthermore, the control pin can get caught even when the authorized key to close, resulting in a reduction in the comfort when closing the lock cylinder. The lock cylinder can be particularly convenient close according to another advantageous embodiment of the invention, when the control pin of Nebenzuhaltung in each Position of the core is arranged exclusively within the core.

Die Nebenzuhaltung vermag gemäß einer anderen vorteilhaften Weiterbildung der Erfindung im unbetätigten Zustand hohe Kräfte abzustützen, wenn in einer Grundstellung der Steuerstift der Nebenzuhaltung von zumindest zwei im Gehäuse angeordneten und in die Fangtasche des Kerns eindringenden Zuhaltungen in den Kern vorgespannt ist.The Nebenzuhaltung is able to support high forces in the unactuated state according to another advantageous embodiment of the invention when biased in a basic position of the control pin Nebenzuhaltung of at least two arranged in the housing and penetrating into the catch pocket of the core tumblers in the core.

Der Schaft 16 des Steuerstiftes 15 ist auf das Zentrum des Kerns 4 gerichtet und in der dargestellten Ausführungsform gegenüber der Stiftzuhaltungen 5 angeordnet. FIG. 2 shows a sectional view through the lock cylinder 1 FIG. 1 along the line II - II. It can be seen here that the control element 11 of the key 2 for controlling the auxiliary tumbler 6 on the key shaft 8 is raised. The shaft 16 of the control pin 15 is directed to the center of the core 4 and arranged in the illustrated embodiment with respect to the pin tumblers 5.

Figur 3 zeigt eine Schnittdarstellung durch den Schließzylinder 1 aus Figur 2 entlang der Linie III - III, dass der Kopf 18 des Steuerstiftes 15 der Nebenzuhaltung 6 und die Fangtasche 17 langgestreckt gestaltet sind. Der Kopf 18 des Steuerstiftes 15 hat seitliche Stützflächen 19 zur Abstützung an Seitenflächen 20 der Fangtasche 17. FIG. 3 shows a sectional view through the lock cylinder 1 FIG. 2 along the line III - III, that the head 18 of the control pin 15 of the Nebenzuhaltung 6 and the catching pocket 17 are designed elongated. The head 18 of the control pin 15 has lateral support surfaces 19 for supporting on side surfaces 20 of the catching pocket 17.

Figur 4 zeigt in einer Schnittdarstellung durch eine weitere Ausführungsform des Schließzylinders 1, welche sich von der aus Figur 2 nur dadurch unterscheidet, dass bei einer Nebenzuhaltung 22 ein Schaft 23 eines Steuerstiftes 24 zu den in Figur 1 dargestellten Stiftzuhaltungen 5 in einem stumpfen Winkel angeordnet ist. Damit wird ein außerhalb des Zentrums des Kerns 4 angeordnetes Steuerteil 21 des Schlüssels 2 abgefragt. FIG. 4 shows in a sectional view through a further embodiment of the lock cylinder 1, which extends from the FIG. 2 only differs in that at a Nebenzuhaltung 22, a shaft 23 of a control pin 24 to the in FIG. 1 shown pin tumblers 5 is arranged at an obtuse angle. This will be an outside queried the center of the core 4 arranged control part 21 of the key 2.

Figur 5 zeigt perspektivisch den Steuerstift 15 der Nebenzuhaltung 6 aus Figur 1. Hierbei ist zu erkennen, dass der Steuerstift 15 auf der dem Schaft 16 abgewandten Seite des Kopfes 18 konkav gestaltet ist und im Wesentlichen die Kontur des Kerns 4 des Schließzylinders 1 hat. Das freie Ende des Schaftes 16 hat eine Steuerspitze 25 zur Abtastung des Steuerelementes 11 des Schlüssels 2. FIG. 5 shows in perspective the control pin 15 of the Nebenzuhaltung 6 FIG. 1 , It can be seen that the control pin 15 is designed concave on the side facing away from the shaft 16 of the head 18 and has substantially the contour of the core 4 of the lock cylinder 1. The free end of the shaft 16 has a control tip 25 for scanning the control element 11 of the key 2.

Figur 6 zeigt den Schließzylinder 1 aus Figur 1 nach einer Drehung des Kerns um 180°. Bei dieser Drehung sind die Kernstifte 12 der Stiftzuhaltungen 5 von den Gehäusestiften 14 getrennt und der Steuerstift 15 gelangt in den Bewegungsbereich der Gehäusestifte 14 der Stiftzuhaltungen 5. FIG. 6 shows the lock cylinder 1 from FIG. 1 after a rotation of the core through 180 °. During this rotation, the core pins 12 of the pin tumblers 5 are separated from the housing pins 14, and the control pin 15 enters the range of movement of the housing pins 14 of the pin tumblers 5.

Figur 7 zeigt vergrößert einen Teilbereich des Schließzylinders 1 mit dem Steuerstift 15 und zwei Stiftzuhaltungen 5. Hierbei ist zu erkennen, dass der Steuerstift 15 bis zur Begrenzung des Kerns 4 in die Fangtasche 17 hineinragt. Da der Kopf 18 die Breite zur Ansteuerung der beiden Stiftzuhaltungen 5 hat, versperrt der Steuerstift 15 in dieser Stellung die Fangtasche 17 für die Kernstifte 12 der Stiftzuhaltungen 5. Der Kern 4 kann damit gegenüber dem Gehäuse 3 weiter verdreht werden. FIG. 7 shows enlarged a portion of the lock cylinder 1 with the control pin 15 and two pin tumblers 5. It can be seen that the control pin 15 extends to the boundary of the core 4 in the catch pocket 17. Since the head 18 has the width for driving the two pin tumblers 5, the control pin 15 locks in this position the catch pocket 17 for the core pins 12 of the pin tumblers 5. The core 4 can thus be further rotated relative to the housing 3.

Figur 8 zeigt den vergrößerten Teilbereich des Schließzylinders 1, wenn der Steuerstift 15 nicht von dem Schlüssel 2 in die in Figur 7 dargestellte Stellung gehalten ist. Der Kopf 18 des Steuerstiftes 15 ist in dieser Stellung in die Fangtasche 17 eingetaucht und gibt damit die Fangtasche 17 für Gehäusestifte 14 der Stiftzuhaltungen 5 frei. Die Gehäusestifte 14 werden von der Kraft der Federelemente 13 in die Fangtasche 18 gedrückt und blockieren die weitere Bewegung des Kerns 4. FIG. 8 shows the enlarged portion of the lock cylinder 1, when the control pin 15 is not from the key 2 in the in FIG. 7 shown position is held. The head 18 of the control pin 15 is immersed in this position in the catching pocket 17 and thus releases the catching pocket 17 for housing pins 14 of the pin tumblers 5. The housing pins 14 are supported by the force of the spring elements 13 pressed into the catch pocket 18 and block the further movement of the core. 4

Figur 9 zeigt einen Schließzylinder 26 in einer weiteren Ausführungsform. Der Schließzylinder 26 unterscheidet sich von dem aus Figur 1 nur dadurch, dass eine Nebenzuhaltung 27 mit zwei in einem Gehäuse 28 angeordneten Zuhaltungen 29 zusammenwirkt. Die in einem Kern 30 angeordnete Nebenzuhaltung 27 und die weiteren Zuhaltungen 29 sind in Figur 10 vergrößert dargestellt. In der Grundstellung des Schließzylinders 26 weisen die weiteren Zuhaltungen 29 in eine Fangtasche 31 der Nebenzuhaltung 27 vorgespannte Kernelemente 32 auf und blockieren damit die Bewegung des Kerns 30. Erst wenn ein Steuerstift 33 der Nebenzuhaltung 27 durch einen nicht dargestellten geeigneten Schlüssel derart bewegt wird, dass die Kernelemente 32 aus der Fangtasche 31 herausgerückt werden, kann der Kern 30 gegenüber dem Gehäuse 28 bewegt werden. Ansonsten ist dieser Schließzylinder 26 wie der aus Figur 1 aufgebaut. FIG. 9 shows a lock cylinder 26 in another embodiment. The lock cylinder 26 is different from that FIG. 1 only in that a Nebenzuhaltung 27 cooperates with two arranged in a housing 28 tumblers 29. The secondary tumblers 27 and the other tumblers 29 arranged in a core 30 are shown in FIG FIG. 10 shown enlarged. In the basic position of the lock cylinder 26, the other tumblers 29 in a catch pocket 31 of Nebenzuhaltung 27 prestressed core elements 32 and thus block the movement of the core 30. Only when a control pin 33 of Nebenzuhaltung 27 is moved by a suitable key, not shown, such that the core elements 32 are moved out of the catch pocket 31, the core 30 can be moved relative to the housing 28. Otherwise, this lock cylinder 26 as the off FIG. 1 built up.
