Description

Die Erfindung bezieht sich auf einen Schließzylin­der mit Stiftzuhaltungen und gleitendem Zylinderkern, bei dem das axiale Gleiten des Zylinderkern diesen mit dem Betätigungsorgan eines Schlosses und/oder eines elektrischen Schalters verbindet.The invention relates to a locking cylinder with tumblers and sliding cylinder core, in which the axial sliding of the cylinder core connects it to the actuator of a lock and / or an electrical switch.

Ein derartiger Schließzylinder bietet den Vorteil, daß ein gewaltsamer Versuch zum Drehen des Zylinder­kerns normalerweise keine Mitnahme des Betätigungsor­gans ermöglicht, da der Zylinderkern daran nicht ange­koppelt ist. Ein solcher Schließzylinder aber kann nach Aufbringen eines ausreichenden Drehmoments durch Ab­scheren der Stifte gewaltsam betätigt werden, worauf der Zylinderkern gleiten und in axiale Kupplungsstel­lung gebracht werden kann.Such a locking cylinder has the advantage that a violent attempt to turn the cylinder core normally does not allow the actuator to be taken along, since the cylinder core is not coupled to it. Such a locking cylinder, however, can be actuated by force after shearing off the pins after application of a sufficient torque, whereupon the cylinder core can slide and be brought into the axial coupling position.

Ziel der Erfindung ist es, einen Schließzylinder der eingangs beschriebenen Art zwecks Erhöhung seiner Sicherheit, insbesondere gegen ein gewaltsames Drehen, zu vervollkommnen.The aim of the invention is to perfect a locking cylinder of the type described in the introduction in order to increase its security, in particular against violent rotation.

Zu diesem Zweck ist der erfindungsgemäße Schließ­zylinder dadurch gekennzeichnet, daß der Zylinderkern beim Drehen in Verriegelungsstellung über die genannten Stifte fest mit einer Buchse verbunden wird, die in einem feststehenden Gehäuse drehbar gelagert ist und in Verschieberichtung feststeht und ein Mittel zum Winkli­gen Weiterschalten in bezug auf das genannte Gehäuse umfaßt.For this purpose, the locking cylinder according to the invention is characterized in that the cylinder core is firmly connected to a socket when rotating in the locking position via the aforementioned pins, which is rotatably mounted in a fixed housing and is fixed in the direction of displacement and a means for angular switching in relation to the mentioned housing includes.

Beim erfindsunsgemäßen Schließzylinder wird bei jedem Versuch eines gewaltsamen Drehens des Zylinder­kerns die Buchse in Drehung versetzt, und der Zylinder­kern dreht sich frei, ohne axial verschoben werden zu können. Vorzugsweise umfassen Zylinderkern und Buchse in Ruhestellung zusätzliche Kupplungsorgane, wodurch die feste winkelige Verbindung des Zylinderkerns mit der Buchse noch verstärkt wird.In the locking cylinder according to the invention, the bushing is rotated with every attempt at a violent rotation of the cylinder core, and the cylinder core rotates freely without being able to be axially displaced. In the rest position, the cylinder core and bushing preferably comprise additional coupling members, as a result of which the fixed angular connection of the cylinder core to the bushing is further reinforced.

In einer bevorzugten Ausführungsform der Erfindung umfassen der Zylinderkern und das Betätigungsorgan zusätzliche Kupplungsorgane, die in Kupplungsstellung des Zylinderkerns zusammenwirken. In diesem Fall wirkt nach einer besonders vorteilhaften Ausführungsform der Erfindung das Kupplungsorgan des Zylinderkerns in Ruhe­stellung mit einem Zusatzorgan der Buchse und in Kupplungsstellung mit einem Zusatzorgan des Betäti­gungsorgans zusammen.In a preferred embodiment of the invention, the cylinder core and the actuating member comprise additional coupling members which cooperate in the coupling position of the cylinder core. In this case, according to a particularly advantageous embodiment of the invention, the coupling member of the cylinder core acts in the rest position with an additional member of the bushing and in Coupling position together with an additional element of the actuator.

Vorzugsweise stützt sich ein axial beweglicher Kolben unter der Wirkung federnder Rückholmittel auf die dem Schlüsseleintritt entgegengesetzte Fläche des Zylinderkerns ab, wodurch ein axiales Rückholen des Zylinderkerns sowie der Buchse über Kupplungsmittel gegen die vordere Fläche des Gehäuses, die auf diese Weise eine gemeinsame Bezugsfläche bildet, gewährlei­stet wird. In diesem Fall ist es vorteilhaft, vorzuse­hen, daß der genannte Kolben in Ruhestellung über Mit­tel zum winkeligen Ankuppeln an das Gehäuse verfügt und diese Mittel in Arbeitsstellung gelöst sind. Auf diese Weise wird das Betätigungsorgan in Ruhestellung über den Kolben an das Gehäuse gekoppelt, wobei jedes direk­te Betätigen dieses Organs unmöglich ist.An axially movable piston is preferably supported under the action of resilient return means on the surface of the cylinder core opposite the key entry, as a result of which an axial return of the cylinder core and the bushing is ensured via coupling means against the front surface of the housing, which in this way forms a common reference surface becomes. In this case, it is advantageous to provide that said piston has means for angular coupling to the housing in the rest position and these means are released in the working position. In this way, the actuating member is coupled to the housing via the piston in the rest position, any direct actuation of this member being impossible.

Die Erfindung wird besser verständlich beim Lesen der folgenden Beschreibung unter Bezugnahme auf die beigeheftete Zeichnung, in der:

  • - Figur 1 eine schematische Ansight im Längs­schnitt mit teilweisem Ausbruch eines Schließzylinders nach einem Ausführungsbeispiel der Erfindung in Ruhe­stellung ist;
  • - Figure 2 ist eine ähnliche Ansicht wie in Figur 1 in eingekuppelter Stellung, und
  • - Figure 3 ist eine auseinandergezogene perspekti­vische Schemaansicht der Organe, die durch Ankoppeln und Einkuppeln zusammenwirken müssen.
The invention will be better understood upon reading the following description with reference to the accompanying drawing, in which:
  • - Figure 1 is a schematic view in longitudinal section with partial breakout of a lock cylinder according to an embodiment of the invention in the rest position;
  • - Figure 2 is a similar view as in Figure 1 in the engaged position, and
  • - Figure 3 is an exploded perspective schematic view of the organs that must interact by coupling and coupling.

Der erfindungsgemäße Schließzylinder umfaßt einen Zylinderkern 1, der sich in einer Buchse oder Hülse 2 dreht, die in einem Zylindergehäuse 3 frei drehbar und nichtgleitend gelagert ist. In Ruhestellung (Figur 1) sind der Zylinderkern 1 und die Buchse 2 in Drehung fest miteinander verbunden über Stiftpaare 4, 5, die durch Federn 6 in Richtung Schlüsselkanal 7 des Zylin­derkerns 1 gedrückt werden. Die Buchse 2 wird außerdem in bezug auf das Gehäuse 3 weitergeschaltet mittels eines Organs 8, das durch eine Feder 9 gegen eine Aussparung 10 des Gehäuses 3 gedrückt wird.The lock cylinder according to the invention comprises a cylinder core 1, which rotates in a bushing or sleeve 2, which is freely rotatable and non-slidingly mounted in a cylinder housing 3. In the rest position (FIG. 1), the cylinder core 1 and the socket 2 are firmly connected to one another in rotation via pairs of pins 4, 5, which are pressed by springs 6 in the direction of the key channel 7 of the cylinder core 1. The socket 2 is also advanced with respect to the housing 3 by means of an organ 8 which is pressed by a spring 9 against a recess 10 of the housing 3.

Beim Einführen des Schlüssels 11 (Figur 2) werden die Stiftpaare 4, 5 gegen die Wirkung ihrer Federn 6 so eingedrückt, daß sie sich im Mantel des Zylinderkerns 1 befinden, der auf diese Weise seine feste Verbindung mit der Buchse 2 verliert. In dieser Stellung wird durch ein Drücken der Spitze 11' des Schlüssels 11 gegen das Ende 7' des Kanals 7 eine Axialverschiebung des Zylinderkerns 1 herbeigeführt, nachdem die Stifte 4 und 5 nicht mehr koaxial sind.When inserting the key 11 (FIG. 2), the pairs of pins 4, 5 are pressed in against the action of their springs 6 so that they are located in the jacket of the cylinder core 1, which in this way loses its fixed connection to the socket 2. In this position, pressing the tip 11 'of the key 11 against the end 7' of the channel 7 brings about an axial displacement of the cylinder core 1 after the pins 4 and 5 are no longer coaxial.

Das dem Eintritt des Schlüsselkanals 7 entgegenge­setzte Ende 1' des Zylinderkerns 1 stützt sich ab gegen einen Kolben 12, der durch eine Feder 13 gegen den Zylinderkern 1 gedrückt wird, so daß in Ruhestellung der Zylinder 1 gegen die Fläche der Scheibe 16 anliegt, die eine gemeinsame Bezugsfläche für den Zylinderkern 1 und die Buchse 2 bildet, die ihrerseits durch die Feder 9 des Organgs 8 angedrückt wird.The opposite to the entry of the key channel 7 end 1 'of the cylinder core 1 is supported against a piston 12 which is pressed by a spring 13 against the cylinder core 1, so that in the rest position of the cylinder 1 rests against the surface of the disc 16, the one common reference surface for the cylinder core 1 and the sleeve 2 forms, which in turn by the spring 9 of the organ 8 is pressed.

Der Kolben 12 ist in das Gehäuse 3 durch Radial­flügel 14 (Figur 3) gekeilt, die in Schlitzen 15 des Gehäuses 3 gleiten.The piston 12 is keyed into the housing 3 by radial vanes 14 (FIG. 3) which slide in slots 15 of the housing 3.

In Ruhestellung sitzen die genannten Flügel 14 des Kolbens 12 in Axialschlitzen 17 eines Schließbartes 18, der drehbar, aber nicht gleitend im Gehäuse 3 gelagert ist, in bezug auf das er durch eine Drehfeder 19 winke­lig zurückgeholt wird. In dieser Ruhestellung ist der Schließbart 18, bei dem es sich um ein Betätigungsorgan für ein Schloß (nicht dargestellt) handelt, in bezug auf den Kolben 12 verkeilt, der seinerseits in bezug auf das Gehäuse 3 verkeilt ist. Die Ausübung einer Kraft auf den Schließbart 18, beispielsweise über das Schloß, läßt eine Entriegelung nicht zu. Im Gegenteil, wenn der Kolben 12 durch den Zylinderkern 1 im Verlauf von dessen Axialverschiebung zurückgedrückt wird, tre­ten die Flügel 14 des Kolbens 12 aus den Schlitzen 17 des Schließbartes 18 aus, und der letztere kann sich in bezug auf das Gehäuse 3 frei drehen.In the rest position, said wings 14 of the piston 12 are seated in axial slots 17 of a cam 18 which is rotatably but not slidably mounted in the housing 3, with respect to which it is angularly returned by a torsion spring 19. In this rest position, the lock bit 18, which is an actuator for a lock (not shown), is wedged with respect to the piston 12, which in turn is wedged with respect to the housing 3. The application of a force on the lock bit 18, for example via the lock, does not allow unlocking. On the contrary, when the piston 12 is pushed back by the cylinder core 1 in the course of its axial displacement, the vanes 14 of the piston 12 emerge from the slots 17 of the cam 18, and the latter can rotate freely with respect to the housing 3.

Der Zylinderkern 1 umfaßt Radialflügel 20, die in Ruhestellung in Radialschlitze 21 der Buchse 2 eingrei­fen, so daß der Zylinderkern 1 und die Buchse 2, die die Role des klassischen Zylindergehäuses spielt, außer über die Stiftpaare 4, 5 durch das Zusammenwirken der Flügel 20 mit den Schlitzen 21 in Drehung fest miteinander verbunden sind.The cylinder core 1 comprises radial vanes 20 which engage in the rest position in radial slots 21 of the socket 2, so that the cylinder core 1 and the socket 2, which plays the role of the classic cylinder housing, except via the pairs of pins 4, 5 by the interaction of the vanes 20 with the slots 21 are firmly connected to each other in rotation.

Im Verlauf der Axialverschiebung des fylinderkerns 1 verlassen die Flügel 20 des Zylinderkerns 1 die Schlitze 21 der Buchse 2 und gelangen in Eingriff mit den Schlitzen 17 des Schließbartes 18, aus dessen Schlitzen 17 die Flügel 14 des Kolbens 12 im Verlauf der durch den Zylinderkern 1 hervorgerufenen Ver­schiebung des Kolbens 12 austreten, wie weiter oben erläutert. Am Ende der Verschiebung des Zylinderkerns 1 (Figure 2) wird dieser am Schließbart 18 eingekuppelt, der jetzt nicht mehr über den Kolben 12 mit dem Gehäuse 3 fest verbunden ist. Durch ein Drehen des Zylinder­kerns 1 durch den Schlüssel 11 wird eine Drehung des Schließbartes 18 hervorgerufen, der den Schloßmecha­nismus betätigt.In the course of the axial displacement of the cylinder core 1, the wings 20 of the cylinder core 1 leave the slots 21 of the bushing 2 and come into engagement with the slots 17 of the locking bit 18, from whose slots 17 the wings 14 of the piston 12 in the course of those caused by the cylinder core 1 Displacement of the piston 12 emerge, as explained above. At the end of the displacement of the cylinder core 1 (Figure 2), this is coupled to the cam 18, which is now no longer firmly connected to the housing 3 via the piston 12. By turning the cylinder core 1 by the key 11, a rotation of the lock bit 18 is caused, which actuates the lock mechanism.

Sobald der Schlüssel 11 losgelassen wird, werden der Schließbart 18 und der Zylinderkern 1 durch die Drehfeder 19 in ihre Ruhestellung zurückgeführt, und die Feder 13 drückt den Kolben 12 und den Schließkern 1 axial zur Ruhestellung in Figur 1 zurück.As soon as the key 11 is released, the lock bit 18 and the cylinder core 1 are returned to their rest position by the torsion spring 19, and the spring 13 presses the piston 12 and the lock core 1 axially back to the rest position in FIG. 1.

Aus Gründen der Sicherheit gegen frontales Einste­chen wird erfindungsgemäß die Stirnfläche der Buchse 2 durch eine Scheibe 16 aus behandeltem Stahl, der den Schlüsseleintritt schützt, und eine Kapsel 22 aus be­handeltem Stahl abgedeckt, die in das Gehäuse 3 einge­faßt ist und auf die sich eine Halterungsgabel 23 des Schließzylinders abstützt, so daß die Kapsel 22 hinter dem Türblech 24 verriegelt ist.For reasons of security against frontal piercing, the end face of the bushing 2 is covered according to the invention by a disk 16 made of treated steel, which protects the key entry, and a capsule 22 made of treated steel, which is enclosed in the housing 3 and on which there is a mounting fork 23 supports the lock cylinder so that the capsule 22 is locked behind the door panel 24.

Die Schutzscheibe 16 des Zylinderkerns 1 steht über diesem radial vor und stützt sich auf die Buchse 2, was die Festigkeit des Zylinderkerns 1 gegen Fron­talschläge erhöht; denn ohne diese Anordnung würden dadurch die Stiftzuhaltungen unmittelbar beansprucht.The protective disk 16 of the cylinder core 1 protrudes radially above this and is supported on the bush 2, which increases the strength of the cylinder core 1 against frontal impacts; because without this arrangement, the pin tumblers would be used directly.
