Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Ver- und Entriegeln einer Schließvorrichtung, insbesondere einer Schließvorrichtung mit einem durch einen schlüsselbetätigten Schließzylinder, der ein feststehendes, hohles Zylindergehäuse mit darin drehbarem, hohlen Innenzylinder und in diesem drehbaren Scheibenzuhaltungen sowie ein daran endseitig angeordnetes Schließmittel umfaßt.The invention relates to a method and a device for locking and unlocking a locking device, in particular a locking device with one operated by a key Lock cylinder, which is a fixed, hollow Cylinder housing with a hollow inner cylinder that can be rotated inside and in this rotatable disc tumblers as well as one on it includes locking means arranged at the end.

Aus der DE 38 13 658 ist ein Schließzylinder mit Scheibenzuhaltungen bekannt. Der Schließzylinder umfaßt ein Gehäuse, eine Zylindertrommel und Scheibenzuhaltungen. Es ist eine beim Einschieben des Schlüssels drehfeste Verdrehsicherungsscheibe vorgesehen, deren Schlüsselöffnung unverdrehbar mit dem Schlüsselprofil zusammenwirkt, so daß der Schlüssel während des Einschiebens bzw. Herausziehens nicht verdreht werden kann. Am Schlüssel ist eine Steuerkurve vorgesehen, durch die die Verdrehsicherungsscheibe aus der drehfesten Stellung in eine drehfreie Stellung überführt wird.From DE 38 13 658 is a lock cylinder with disc tumblers known. The lock cylinder comprises a housing, a cylinder drum and disc tumblers. It is one when you insert the key Non-rotating lock washer provided, the key opening non-rotatably cooperates with the key profile, so that the Key not twisted during insertion or removal can be. A control curve is provided on the key, through which the anti-rotation washer from the non-rotating position to a non-rotating position Position is transferred.

Die EP-A-0 622 508 offenbart eine Schließvorrichtung bestehend aus einem Schlüssel und einem Schließzylinder mit einem Zylinderkern, der in einem Gehäuse drehbar ist und einen sich axial erstreckenden Kanal zum Einführen eines Schlüssels aufweist, der durch plattenförmige Zuhaltungen verläuft, die axial aufeinanderfolgend angeordnet sind, so daß sie in dem Zylinderkern drehbar sind, und der Bartstufen umfaßt, die an dem Schlüsselschaft vorgesehen sind und die Zuhaltungen in eine Stellung bewegen können, die eine Drehung des Zylinderkerns freigibt. Die Bewegung der Zuhaltungen ist als eine Drehbewegung um die Achse des Schlüsselschaftes herum entworfen, und ihr Bewegungsbereich ist durch Anschläge begrenzt. Am Umfang jeder Zuhaltung ist zumindest eine Ausnehmung vorgesehen, in die ein Sperrmittel eintreten kann, das eine Drehung des Zylinderkerns freigibt.EP-A-0 622 508 discloses a locking device consisting of a Key and a lock cylinder with a cylinder core, which in a housing is rotatable and an axially extending channel for Inserting a key that has plate-shaped tumblers runs, which are arranged axially in succession, so that they in the cylinder core are rotatable, and includes the beard steps on the Key shafts are provided and the tumblers in one position can move, which releases a rotation of the cylinder core. The movement of the tumblers is a rotational movement around the axis of the Key shaft designed around, and their range of motion is through Attacks limited. There is at least one recess on the circumference of each tumbler provided, into which a locking means can enter that a rotation of the cylinder core releases.

Eine weitere Schließvorrichtung ist aus der DE 34 21 754 C2 bekannt.Another locking device is from the DE 34 21 754 C2 known.

Bei einer Schließvorrichtung dieser Art ist beispielsweise der Schließzylinder mit seinem hohlen Innenzylinder und den Scheibenzuhaltungen in eine Sackbohrung eines Gehäuses eingesteckt. Das Zylinderschloß weist einen drehbar gelagerten Hohlzylinder und in diesem eine Vielzahl von begrenzt drehbar gelagerten und mit einem Schlüssel verdrehbaren Scheibenzuhaltungen auf. Zwischen den Scheibenzuhaltungen sind axial wirksame Federscheiben angeordnet. Als Sperrmittel ist eine zylindrische Sperrstange angeordnet. Solange der Schließmechanismus in Sperrstellung steht, wird eine Drehung des inneren Zylinders bezüglich des Zylindergehäuses verhindert, und zwar durch die Sperrstange. Diese befindet sich mit einem Teil in einer in der inneren Oberfläche des Zylindergehäuses eingelassenen axialen Nut und mit einem anderen Teil in einem im Umfang des inneren Zylinders ausgesparten Schlitz. Wenn die Scheibenzuhaltungen mit dem Schlüssel in die Freigabestellung gedreht werden, bilden die Ausnehmungen der einzelnen Scheiben gemeinschaftlich eine Nut, in die die Sperrstange einfallen kann, wodurch der innere Zylinder entsperrt und das Schloß geöffnet werden kann. Die zwischen den Zuhaltungsscheiben angeordneten Federscheiben weisen jeweils eine zentrale zylindrische Lochung auf, die so groß bemessen ist, daß der entsprechende Schlüssel berührungslos hindurchgeführt werden kann.In a locking device of this type, for example the lock cylinder with its hollow inner cylinder and the Disc tumblers inserted into a blind hole in a housing. The cylinder lock has a rotatably mounted Hollow cylinder and in this a variety of limited rotation stored disc locks that can be turned with a key on. Between the disc tumblers are axial effective spring washers arranged. As a blocking agent is one cylindrical locking rod arranged. As long as the locking mechanism is in the locked position, a rotation of the inner Prevents cylinders with respect to the cylinder housing, and through the locking rod. This is with a Part in a in the inner surface of the cylinder housing recessed axial groove and with another part in a slot recessed in the circumference of the inner cylinder. When the disc tumblers with the key in the release position are rotated, form the recesses of the individual Disks jointly a groove in which the locking rod can occur, which unlocks the inner cylinder and the lock can be opened. The between the tumbler discs arranged spring washers each have a central cylindrical perforation, which is dimensioned so large that the corresponding key is passed through without contact can be.

Obwohl sich derartige Schlösser in der Vergangenheit bewährt haben, besteht ein Nachteil darin, daß die einzelnen Scheibenzuhaltungen mittels eines nicht vollständig eingesteckten Schlüssels verdreht werden können, so daß der Benutzer annehmen muß, die Schließvorrichtung sei defekt. Bei übermäßiger Krafteinwendung kann der Benutzer dabei den Schlüssel verbiegen oder abbrechen.Although such locks have proven their worth in the past have a disadvantage is that the individual disc tumblers by means of a not fully inserted Key can be rotated so that the user can accept must, the locking device is defective. With excessive The user can bend the key when applying force or cancel.

Außerdem lassen derartige Schlösser hinsichtlich der erzielbaren Sicherheit aufgrund einer nicht auszuschließenden Abtastbarkeit zu wünschen übrig.In addition, locks of this type are achievable Security due to a traceability that cannot be ruled out to be desired.

Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung anzugeben, welche das Ver- und Entriegeln einer Schließvorrichtung verbessern, insbesondere hinsichtlich der Handhabung und der Sicherheit.The object of the invention is a method and an apparatus specify which locking and unlocking a locking device improve, especially with regard to handling and security.

Die gestellte Aufgabe wird durch die unabhängigen Ansprüche 1, 5, 6, 7, 10, 12, und 13 gelöst, besonders vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The task is set by the independent claims 1, 5, 6, 7, 10, 12, and 13 solved, particularly advantageous embodiments the invention are specified in the subclaims.

Durch die gemäß der Erfindung vorgegebene Codierung der einzelnen Schritte zum Ver- bzw. Entriegeln einer Schließvorrichtung werden die Funktions- und Betriebssicherheit erhöht.
Außerdem wird eine absichtliche und unabsichtliche Verdrehung der Scheibenzuhaltungen relativ zueinander unmöglich, kann also beispielsweise nicht durch Vibrationen oder dergleichen herbeigeführt werden oder durch einen nicht vollständig eingesteckten Schlüssel erfolgen oder aber durch in das Schlüsselloch eingeführte Drähte oder dergleichen bewerkstelligt werden. Zum Betätigen der Schließvorrichtung ist es erforderlich, daß zunächst der Schlüssel vollständig in den Einsteckkanal eingesteckt wird, der durch die entsprechenden Lochungen der Scheibenzuhaltungen gebildet ist. Erst bei vollständig eingestecktem Schlüssel wird das zweite Sperrmittel entsperrt, mittels dessen bis dahin der Innenzylinder mit dem Zylindergehäuse gegen Relativdrehung gesperrt war. Durch geringfügiges Drehen des Schlüssels um wenige Grad in der vorgeschriebenen Betätigungsrichtung wird dann das dritte Sperrmittel entriegelt, so daß die Scheibenzuhaltungen relativ zum Innenzylinder verdrehbar sind. Anschließend kann dann mittels des Schlüssels die Drehung der Scheibenzuhaltungen in die Sollposition erfolgen, in welcher die Freitgabestellung des ersten Sperrmittels erreicht ist. Bei weiterer Drehung wird dann das Schließmittel mittels des Schlüssels gedreht, so daß das entsprechend ausgestattete Schloß in die Offenstellung verstellt ist. Beim Schließen des Schlosses erfolgt die Drehung des Schlüssels im entgegengesetzten Drehsinn, wobei die Sperrmittel in entgegengesetzter Reihenfolge in die Sperrstellung überführt werden.

In addition, an intentional and unintentional rotation of the disc tumblers relative to each other is impossible, for example, cannot be caused by vibrations or the like, or can be done by a key that is not fully inserted, or can be accomplished by wires or the like inserted into the keyhole. To actuate the locking device, it is necessary that the key is first completely inserted into the insertion channel, which is formed by the corresponding perforations in the disc tumblers. The second locking means, by means of which the inner cylinder with the cylinder housing was previously locked against relative rotation, is only unlocked when the key is fully inserted. The third locking means is then unlocked by turning the key slightly by a few degrees in the prescribed actuation direction, so that the disc tumblers can be rotated relative to the inner cylinder. The disk tumblers can then be rotated into the desired position by means of the key, in which the release position of the first locking means is reached. Upon further rotation, the locking means is then rotated by means of the key, so that the correspondingly equipped lock is adjusted to the open position. When the lock is closed, the key is turned in the opposite direction, the locking means being moved into the locking position in the opposite order.

Das erste Sperrmittel ist vorzugsweise als Sperrstange in herkömmlicher Bauart ausgebildet, wie beispielsweise aus der gattungsbildenden Druckschrift bekannt. Das zweite Sperrmittel ist vorzugsweise ein doppelt wirkender mit Schließfedern beaufschlagter Schubriegel, der zum Beispiel durch die Spitze des eingesteckten Schlüssels in die Entriegelungsposition entgegen Federkraft verschoben wird. Das dritte Sperrmittel kann ebenfalls eine zylindrische Stange, Stifte, Kugeln oder Walzen sein. Es ist auch eine Anordnung von mehreren in Reihe zueinander angeordneten Kugeln möglich, die dann quasi ein stangenförmiges Sperrmittel darstellen. The first locking means is preferably in the form of a locking rod conventional design, such as from the generic document known. The second blocking agent is preferably a double-acting with closing springs acted slide latch, which, for example, by the Tip of the inserted key in the unlocked position is moved against spring force. The third blocking agent can also be a cylindrical rod, pins, Balls or rollers. It is also an arrangement of several balls arranged in a row are possible, which then effectively represent a rod-shaped locking means.
