Description

Schließvorrichtung mit Schließzylinder und Flachschlüssel Locking device with lock cylinder and flat key

Die Erfindung betrifft eine Schließvorrichtung mit Schließzylinder und Flachschlüssel, mit in den Schlüsselkanal des Zylinderkerns hineinragendem Einschubsperrglied, welchem eine Ausnehmung am Flachschlüssel zugeordnet ist.The invention relates to a locking device with a lock cylinder and flat key, with a push-in locking member protruding into the keyway of the cylinder core, which is assigned a recess on the flat key.

Eine derartige Schließvorrichtung ist bekannt aus der DE-PS 1 812 051, wobei am rückwärtigen Ende des Zylinderkerns ein halbmondförmiges Einschubsperrglied formschlüssig eingesteckt ist, welches mit Vorsprüngen in den Schlüsselkanal hineinragt. Dementsprechend besitzt der Flachschlüssel von seinem Einsteckende her ausgehende Profilnuten. Fehlen diese bei einem Flachschlüssel, der zwar die entsprechenden Schließkerben ausbildet, so läßt sich dieser doch nicht vollständig in den Schlüsselkanal einschieben wegen des Einschubsperrgliedes. Bei dieser Bauform müssen die in Form von Nuten ausgebildeten Ausnehmungen des Flachschlüssels stets von der Schlüsselspitze ausgehen. Ferner erfährt der Zylinderkern durch das halbmondförmige Einschubsperrglied eine erhebliche Schwächung.Such a locking device is known from DE-PS 1 812 051, with a crescent-shaped insertion locking member at the rear end of the cylinder core is inserted positively, which protrudes with projections into the key channel. The flat key accordingly has its insertion end Profile grooves. If this is missing with a flat key, it has the corresponding Forms locking notches, so this cannot be completely inserted into the keyway push in because of the push-in locking member. With this design, they must be in the form recesses of the flat key formed by grooves always from the key tip go out. Furthermore, the cylinder core experiences through the crescent-shaped insertion locking member a significant weakening.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, eine Schließvorrichtung der vorausgesetzten Art so auszugestalten, daß die Ausnehmung nicht von der Schlüsselspitze auszugehen braucht und für das Einschubsperrglied nur eine querschnittskleine Aussparung am Zylinderkern vorzusehen ist.The object of the invention is based on the object of a locking device of the type required so that the recess does not come from the tip of the key needs to go out and only a small cross-section recess for the insertion locking member is to be provided on the cylinder core.

Gelöst wird diese Aufgabe durch das Kennzeichen des Anspruchs 1.This problem is solved by the characteristic of claim 1.

Der Unteranspruch stellt eine vorteilhafte Weiterbildung des Anspruchs 1 dar.The sub-claim represents an advantageous further development of the claim 1 represents.

Zufolge derartiger Ausgestaltung ist eine gattungsgemäße Schließvorrichtung mit Schließzylinder und Flachschlüssel angegeben, bei welchem die Ausnehmung am Flachschlüssel nicht bis zur Schlüsselspitze zu reichen braucht. Dies erweist sich insbesondere bei solchen Flach schlüsseln als günstig, bei denen die Schließkerben an der einen Schmalseite des Schlüsselschafts angeordnet sind. Die die Zuhaltungsstifte einordnende Auflaufschräge des Schlüsselschafts wird daher nicht flächen reduziert. Auch entstehen dadurch weniger scharfe Kanten im Bereich der Schlüsselspitze, die bei einem losen Herumtragen des Schlüssels in einer Tasche zu Beschädigungen derselben führen könnten. Das Einschubsperrglied neben der Breitseite des Schlüssel kanals vorzusehen, bringt unterbringungstechnische Vorteile. Eine von der Mantelfläche des Zylinderkerns ausgehende Radialaussparung bringt den Vorteil einer geringen Querschnittsreduzierung, so daß der Schließzylinder nicht gefährdend geschwächt wird. Die Aussparung ist so zu gestalten, daß in zwei Endbereichen ein Durchtritt zum Schlüsselkanal auftritt. Das weiter innenliegende Ende des als wippenförmiger Doppelhebel ausgebildeten Einschubsperrglieds kann dann in den Schlüssel kanal eintauchen. Wird nun der entsprechend gestaltete Flachschlüssel, der auf seiner Breitseite die Ausnehmung ausbildet, eingeschoben, so übt in der ersten Einschubphase der Flachschlüssel keine Wirkung auf das Einschubsperrglied aus. Erst wenn die Schlüsselspitze das in den Schlüsselkanal ragende Ende des Doppelhebels beaufschlagt, führt dieses zu einem zwangsläufigen Verschwenken des Doppelhebels. Dann erstreckt sich jedoch die Ausnehmung an der Flachschlüssel-Breitseite bereits auf Höhe des anderen, den Tastkopf ausbildenden Endes des Doppelhebels, so daß der Tastkopf störungsfrei in die Ausnehmung einschwenken kann, während von der Schlüsselspitze das weiter einwärts liegende Ende des Doppelhebels aus dem Schlüsselkanal verdrängt wird. Die Ausnehmung ist so lang bemessen, daß der Flachschlüssel danach bis in seine End-Einschubstellung verlagerbar ist.As a result of such a configuration is a generic locking device indicated with lock cylinder and flat key, in which the recess on the Flat key does not need to reach to the tip of the key. This turns out to be especially with such flat keys as favorable, in which the locking notches are arranged on one narrow side of the key shaft. The tumbler pins Classifying run-up slope of the key shaft is therefore not reduced in area. This also results in less sharp edges in the area of the key tip, which If the key is carried around loosely in a pocket, damage to the same could lead. The slide-in locking member next to the broad side of the key channel providing accommodation brings advantages. One from the outer surface The radial recess emanating from the cylinder core has the advantage of a small one Cross-section reduction, so that the lock cylinder is not weakened in a dangerous way will. The recess is to be designed so that there is a passage in two end areas occurs to the key channel. The more inward end of the rocker-shaped Double lever trained insertion locking member can then dip into the key channel. If the correspondingly designed flat key, which is on its broad side, the Forms recess, pushed in, so exercises the flat key in the first push-in phase has no effect on the slide-in locking member. Only when the key tip does that If the end of the double lever protruding into the key channel is applied, this leads to an inevitable pivoting of the double lever. Then, however, extends the Recess on the Flat wrench broadside already at the height of the the other end of the double lever forming the probe head, so that the probe head is free from interference Can pivot into the recess while the key tip continues inward end of the double lever is displaced from the keyway. the The recess is so long that the flat key then reaches its end insertion position is relocatable.

Wird ein Flachschlüssel verwendet, der zwar die entsprechenden Schließkerben ausbildet, aber nicht die Ausnehmung besitzt, so läßt sich dieser nur so weit einschieben, bis die Schlüsselspitze gegen das einwärts liegende Ende des Doppelhebels tritt. Dann ist jedoch das Verschwenken des Doppelhebels nicht möglich, weil der Tastkopf keine Ausnehmung vorfindet, in welche er ausweichen kann. Auch ein Flachschlüssel mit falsch placierter Ausnehmung gestattet nicht das Schließen des Schließzylinders. Ist z. B. die Ausnehmung zu kurz gestaltet, ist zwar nach Erreichen des einwärts liegenden Endes des Doppelhebels ein Verschwenken möglich. Bei weiterem Einschieben muß dann der Tastkopf wegen der zu kurz bemessenen Ausnehmung diese verlassen, was zu einem Verschwenken des Doppelhebels führt, wobei dieser in Klemmstellung zur Breitfläche des Flachschlüssels tritt und das weitere Einschieben verhindert. Durch entsprechende Länge des Doppelhebels und Unterbringung desselben im Zylinderkern sowie entsprechende Positionierung der Ausnehmung an der Flachschlüssel-Breitseite läßt sich eine zusätzliche Verschleierung erzielen, die die Aufsperrsicherheit einer solchen Schließvorrichtung erhöht. Auch ist das Abtasten mittels Hilfswerkzeugen weitgehend verhindert. Will man nämlich mit einem solchen das einwärts liegende Ende des Doppelhebels erreichen, so führt gleichzeitig bei einem Verschwenken des Doppelhebels der Tastkopf zu einer Blockierung des Hilfswerkzeuges, so daß weitere Manipulationen ausgeschlossen sind. Mit einfachen zusätzlichen Mitteln kann das Einschubsperrglied noch eine Zuhaltungsfunktion übernehmen. Es ist lediglich erforderlich, den Doppelhebel so abzufedern, daß ein dem Tastkopf gegenüberliegender Sperrfinger in eine Nut des Schließzylindergehäuses eingreift. Dann ist ein Verdrehen des Zylinderkerns unmöglich, selbst wenn die entsprechenden Zuhaltungsstifte richtig eingeordnet sein sollten. Um den Zylinderkern drehen zu können, ist der richtige Flachschlüssel erforderlich, der den Doppelhebel so verschwenkt, daß der Tastkopf in die Ausnehmung eingreift, während gleichzeitig der Sperrfinger aus der Nut des Schließzylindergehäuses ausschwenkt.A flat key is used that has the corresponding locking notches forms, but does not have the recess, it can only be pushed in so far until the tip of the key hits the inward end of the double lever. Then, however, the pivoting of the double lever is not possible because the probe head finds no recess into which he can evade. Also a flat key with an incorrectly placed recess does not allow the locking cylinder to be closed. Is z. B. made the recess too short, although after reaching the inward pivoting is possible at the end of the double lever. With further insertion then the probe head must leave this because of the too short dimensioned recess, what leads to pivoting of the double lever, this being in the clamping position for The broad surface of the flat key occurs and prevents further insertion. By corresponding length of the double lever and its placement in the cylinder core as well as appropriate positioning of the recess on the flat wrench broad side an additional concealment can be achieved, which increases the security of a such locking device increases. Scanning is also possible using auxiliary tools largely prevented. If you want something inward with one of these Reach the end of the double lever, it results at the same time when pivoting the Double lever of the probe head to block the Auxiliary tool, so that further manipulations are excluded. With simple additional resources the slide-in blocking element can still take on a tumbler function. It is just required to cushion the double lever so that one of the probe head opposite Locking finger engages in a groove in the lock cylinder housing. Then there is a twist of the cylinder core impossible even if the corresponding tumbler pins are correct should be classified. To be able to rotate the cylinder core, is the right one Flat key required, which swivels the double lever so that the probe head engages in the recess, while at the same time the locking finger out of the groove of the Lock cylinder housing swings out.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Fig. 1 bis 5 erläutert. Es zeigt Fig. 1 einen Längsschnitt durch einen Schließzylinder während des Einführens eines entsprechend gestalteten Flachschlüssels, welcher auf seiner Breitseite die erforderliche Ausnehmung besitzt, Fig. 2 eine der Fig. 1 entsprechende Darstellung, welche veranschaulicht, daß die Schlüsselspitze das einwärts liegende Ende des Doppelhebels erreicht hat, Fig. 3 ebenfalls eine den vorangegangenen Figuren entsprechende Darstellung, wobei der Flachschlüssel den Doppelhebel so verschwenkt hat, daß dessen Tastkopf in der Ausnehmung einliegt, Fig. 4 in stark vergrößerter perspektivischer Darstellung den Doppelhebel und Fig. 5 den Flachschlüssel in perspektivischer Darstellung.An exemplary embodiment of the invention is illustrated below with reference to FIG Fig. 1 to 5 explained. 1 shows a longitudinal section through a lock cylinder while inserting a correspondingly designed flat key, which on its broad side has the required recess, FIG. 2 one of FIG. 1 corresponding Representation showing that the key tip is the inward one Has reached the end of the double lever, Fig. 3 also one of the previous figures corresponding illustration, with the flat key pivoting the double lever has that the probe head rests in the recess, Fig. 4 in strong enlarged perspective view of the double lever and FIG. 5 the flat key in perspective view.

Die Schließvorrichtung besitzt einen Schließzylinder 1 und einen Flachschlüssel 2. Letzterer setzt sich aus einem Schlüsselschaft 3 und einer Handhabe 4 zusammen. An der einen Schmalkante des Schlüsselschaftes 3 befinden sich hintereinanderliegende Schließkerben 5, die zur Einordnung von schließzyl inderseitigen, nicht dargestellten stiftartigen Zuhaltungen dienen. Den Schließkerben 5 ist an der Schlüsselspitze S eine Auflaufschräge 6 vorgeordnet. Ferner befindet sich am Schlüsselschaft an der einen Flachschlüssel-Breitseite eine sich in Einschubrichtung erstreckende, rinnenartige Ausnehmung 7. Diese beginnt mit Abstand von der Schlüsselspitze S. Wie aus der Zeichnung ersichtlich, verjüngt sich die Ausnehmung 7 zu ihrem Boden 7' hin, wodurch eine ringsumlaufende Schrägflanke 7" gebildet wird.The locking device has a lock cylinder 1 and a flat key 2. The latter is composed of a key shaft 3 and a handle 4. On one narrow edge of the key shaft 3 are located one behind the other Lock notches 5, the inderside for the classification of lock cylinder, not shown Pin-like tumblers are used. The locking notch 5 is at the tip of the key S a ramp 6 upstream. There is also on the key shaft one of the flat wrench broadsides has one extending in the direction of insertion, Channel-like recess 7. This begins at a distance from the key tip S. As can be seen from the drawing, the recess 7 tapers towards its bottom 7 ', whereby a circumferential sloping flank 7 "is formed.

Bestandteil des Schließzylinders 1 ist ein Schließzylindergehäuse 8. In einer Bohrung 9 desselben ist ein Zylinderkern 10 drehbar, jedoch axial unverschieblich gelagert. Mittig weist der Zylinderkern einen Schlüsselkanal 11 auf, der bis zur einen Mantelwand des Schließzylinderkerns reicht. In dem Zylinderkern 10 sind bekannterweise nicht veranschaulichte kernseitige Zuhaltungsstifte in entsprechenden Bohrungen geführt, die mit schließzylindergehäuseseitigen Zuhaltungsstiften fluchten. Durch die Schließkerben 5 des Flachschlüssels 2 werden die Zuhaltungsstifte so aus- gerichtet, daß deren Trennfuge auf Höhe der Mantelfläche des Zylinderkerns liegt, was das anschließende Drehen des Zylinderkerns zuläßt.A lock cylinder housing is part of the lock cylinder 1 8. In a bore 9 of the same, a cylinder core 10 is rotatable, but axially immovable stored. In the center of the cylinder core has a key channel 11 that extends up to a jacket wall of the lock cylinder core is enough. In the cylinder core 10 are known Not illustrated core-side tumbler pins in corresponding bores guided, which are aligned with the locking pins on the lock cylinder housing side. By the locking notches 5 of the flat key 2, the tumbler pins are directed, that the parting line is at the level of the lateral surface of the cylinder core, what the subsequent Rotation of the cylinder core allows.

In dem Zylinderkern 10 befindet sich eine von dessen Mantelfläche ausgehende Aussparung 12. Diese ist vom Schlüsselkanal 11 durch eine dünne Wand 13 getrennt. In der Aussparung 12 lagert ein Einschubsperrglied 14, welches als neben der Breitseite des Schlüssel kanals 11 liegender wippenförmiger Doppelhebel gestaltet ist. Etwa mittig besitzt dieser eine Lagerhöhlung 15, der von einem quer zur Aussparung 12 verlaufenden Lagerzapfen 16 des Zylinderkerns 10 durchsetzt wird. Das weiter schlüsselkanaleinwärts liegende Ende 17 des Doppelhebels ist abgewinkelt, durchsetzt eine Queröffnung 18 und ragt in den Schlüsselkanal 11. Das andere Ende 19 des Doppelhebels bildet einen Tastkopf 20, welcher ebenfalls in eine Queröffnung 21 eintritt, jedoch noch nicht in den Schlüsselkanal 11 einschwenkt. Dem Tastkopf 20 gegenüber liegt ein materialeinheitlich vom Ende 19 ausgehender Sperrfinger 22. Dieser greift in Grundstellung des Einschubsperrgliedes gemäß Fig. 1 in eine in Längsrichtung des Schließzylindergehäuses 8 verlaufende Nut 23. Eine Druckfeder 24 beaufschlagt dabei das Einschubsperrglied 14 in Sperrichtung.In the cylinder core 10 there is one of its outer surface outgoing recess 12. This is from the key channel 11 through a thin wall 13 separated. In the recess 12 is a push-in locking member 14, which as next to the broad side of the key channel 11 lying rocker-shaped double lever is designed. Approximately in the middle of this has a bearing cavity 15, which is transverse from one to the recess 12 extending bearing journal 16 of the cylinder core 10 is penetrated. The end 17 of the double lever, which is further towards the inside of the key channel, is angled, passes through a transverse opening 18 and protrudes into the key channel 11. The other end 19 of the double lever forms a probe head 20, which is also in a transverse opening 21 enters, but has not yet pivoted into the key channel 11. The probe 20 opposite is a locking finger 22 extending from the end 19 of the same material. This engages in the basic position of the insertion locking member according to FIG. 1 in a Groove 23 running in the longitudinal direction of the lock cylinder housing 8. A compression spring 24 acts on the insertion locking member 14 in the blocking direction.

Letztere stützt sich einerseits an der Wand 13 zwischen Aussparung 12 und Schlüssel kanal 11 ab und andererseits am Boden einer Aussparung des Endes 19 des Doppelhebels. So wird der Sperrfinger 22 in die Nut 19 gezwungen, während das Ende 17 in den Schlüsselkanal 11 eintaucht.The latter is supported on the one hand on the wall 13 between the recess 12 and key channel 11 from and on the other hand at the bottom of a recess of the end 19 of the double lever. So the locking finger 22 is forced into the groove 19 while the end 17 is immersed in the keyway 11.

Sowohl das abgewinkelte Ende 17 als auch der Tastkopf 20 sind gerundet gestaltet, wodurch Auflaufzonen für die Spitze des Schlüsselschaftes gebildet werden.Both the angled end 17 and the probe head 20 are rounded designed, whereby run-up zones are formed for the tip of the key shaft.

Es ergibt sich folgende Wirkungsweise: Wird der Flachschlüssel 2 in den Schlüsselkanal 11 des Zylinderkerns 10 eingeschoben, so kann hierbei die Stellung gemäß Fig. 1 auftreten. In dieser entsprechenden Einschubphase findet noch keine Beaufschlagung des Einschubsperrgliedes 14 statt. Bei weiterem Einschieben wird bspw. die Stellung gemäß Fig. 2 erreicht.The effect is as follows: If the flat key 2 in the key channel 11 of the cylinder core 10 is inserted, the position occur according to FIG. In this corresponding insertion phase there is no Acting on the insertion locking member 14 instead. If you continue to insert For example, the position according to FIG. 2 is reached.

Dann liegt die Schlüsselspitze S vor dem abgewinkelten Ende 17 des Einschubsperrgliedes 14, während der Tastkopf 20 sich bereits im Anfangsbereich der Ausnehmung 7 der Flachschlüssel-Breitseite erstreckt. Das bedeutet, daß das Maß x zwischen abgewinkeltem Ende 17 und Tastkopf 20 größer ist als der Abstand y der Ausnehmung 7 von der Schlüsselspitze S, vergl. Fig. 2. Durch weiteres Einschieben des Flachschlüssels wird nun über die Schlüsselspitze und Ende 17 der Doppelhebel verschwenkt, wobei dessen Tastkopf 20 in die Ausnehmung 7 eintaucht.Then the key tip S is in front of the angled end 17 of the Insertion locking member 14, while the probe 20 is already in the initial area the recess 7 of the flat wrench broad side extends. That means that Dimension x between the angled end 17 and probe head 20 is greater than the distance y of the recess 7 from the key tip S, see FIG. 2. By further insertion of the flat key is now over the key tip and end 17 of the double lever pivoted, the probe head 20 dipping into the recess 7.

Nach beendigtem Einschieben des Schlüssels erstreckt sich dann der Tastkopf 20 am anderen Ende der Ausnehmung 7, während das Ende 17 den Schlüsselkanal vollständig verlassen hat und an der zugekehrten Schlüsselschaft-Breitseite anliegt. Ferner hat mit diesem Verschwenken des doppelhebelartigen Einschubsperrgliedes 14 der Sperrfinger 22 die Nut 23 des Schließzylindergehäuses 8 verlassen. Da in dieser Einschubendstellung des Flachschlüssels auch die entsprechenden Zuhaltungen eingeordnet wurden, kann der Schließzylinderkern 10 gedreht werden.After the key has been inserted, the Probe 20 at the other end of the recess 7, while the end 17 is the key channel has left completely and is in contact with the broad side of the key shaft that is facing it. Furthermore, with this pivoting of the double lever-like insertion locking member 14 the locking finger 22 leave the groove 23 of the lock cylinder housing 8. Because in this Insertion end position of the flat key also includes the corresponding tumblers the lock cylinder core 10 can be rotated.

Beim Abziehen des Flachschlüssels in der entsprechenden Drehstellung des Zylinderkerns verschwenkt in der entsprechenden Zwischenstellung der Doppelhebel zufolge Federbelastung, bspw. in die Stellung gemäß Fig. 2, so daß die weitere Abzugsbewegung nicht beeinträchtigt wird.When removing the flat key in the corresponding turning position of the cylinder core is pivoted in the corresponding intermediate position of the double lever According to spring loading, for example. In the position shown in FIG. 2, so that the further trigger movement is not affected.

Wird ein Flachschlüssel eingeschoben, der keine Ausnehmung besitzt, so ist dieser nur bis zur Stellung gemäß Fig. 2 einschiebbar. Dann tritt beim weiteren Einschieben eine Blockierung auf. Auch ist ein Flachschlüssel nicht einschiebbar, bei welchem der Abstand y größer ist als das Maß x. Schließlich scheidet das Einstecken eines Flachschlüssels aus, welcher eine zu kurze Ausnehmung besitzt.If a flat key is inserted that has no recess, so this can only be inserted up to the position shown in FIG. Then occurs at the further Slide in a blockage. A flat key cannot be inserted either, at which the distance y is greater than the dimension x. Finally, the plug is part a flat wrench with a recess that is too short.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All mentioned in the description and shown in the drawing New features are essential to the invention, even if they are not in the claims are expressly claimed.
