Description
Die Erfindung bezieht sich auf einen Schließzylinder mit Zuhaltungsplättchen, umfassend ein Zylindergehäuse mit einem darin drehbar untergebrachten Zylinderkern, der mit jeweils der Wirkung einer Rückholfeder ausgesetzten Zuhaltungsplättchen ausgerüstet ist.The invention relates to a locking cylinder with tumbler plate, comprising a cylinder housing with a cylinder core rotatably accommodated therein, which is equipped with the action of a return spring exposed tumbler plate.
Solche Schließzylinder finden Verwendung z. B. zum Betätigen eines Tür-, Kofferraum- oder Kraftstoffeinfüllstutzenschlosses eines Kraftfahrzeugs, d. h. daß derselbe Schlüssel mehrere Schlösser einer Anlage schließen kann.Such lock cylinders are used for. B. for operating a door, trunk or fuel filler lock of a motor vehicle, d. H. that the same key can lock several locks in one system.
In diesem Fall bedingt die Erneuerung eines schadhaften Schließzylinders, beispielsweise nach versuchtem Einbruch, die Verwendung eines neuen, zusätzlichen Schlüssels, der nur für das neue Schloß zu gebrauchen ist, was sich recht unangenehm auswirkt. Zudem wird der Selbstkostenpreis um den Preis dieses zusätzlichen Schlüssels erhöht.In this case, the replacement of a defective locking cylinder, for example after an attempted break-in, requires the use of a new, additional key that can only be used for the new lock, which has a rather unpleasant effect. In addition, the cost price is increased by the price of this additional key.
Darüber hinaus wird bei einer Hauptschlüsselanlage im allgemeinen von einem Hauptschließzylinder ausgegangen, der bereits mit einem Schlüssel ausgerüstet ist und nach einer unterschiedlichen Technik hergestellt werden kann.In addition, a master key system generally starts with a master lock cylinder which is already equipped with a key and can be manufactured using a different technique.
Das ist der Fall beispielsweise bei einer Hauptschlüsselanlage für Kraftfahrzeuge, zu der gehöhren ein Hauptschließzylinder, der als Diebstahlsicherung ausgebildet ist und mit Plättchenzuhaltungen arbeiten kann, sowie die Schließzylinder für Türen, Kofferraum Handschuhfach und Klappe oder Deckel des Kraftstoffeinfüllstutzens. Um eine solche Hauptschlüsselanlage anhand des Schlüssels für den Hauptschließzylinder verwirklichen zu können, müssen die verschiedenen Schließzylinder manipuliert werden, um dort die Zylinderkerne einzusetzen, in die zuvor die Zuhaltungsplättchen und die Federn eingebaut wurden.This is the case, for example, with a master key system for motor vehicles, which includes a master lock cylinder, which is designed as an anti-theft device and can work with plate tumblers, as well as the lock cylinders for the doors, trunk, glove compartment and flap or lid of the fuel filler neck. In order to be able to implement such a master key system using the key for the master lock cylinder, the various lock cylinders must be manipulated in order to insert the cylinder cores into which the tumbler plates and the springs were previously installed.
Die Erfindung zielt darauf ab, den Einbau von Zuhaltungsplättchen in einen zuvor fertig montierten Schließzylinder zu ermöglichen, so daß es möglich ist, vollständige Schließzylinder ohne Zuhaltungsplättchen herzustellen und auf Lager zu legen und die Zuhaltungsplättchen erst im Endstadium einzubauen, d. h. kurz vor Erneuerung des schadhaften Schließzylinders oder bei der Zusammenstellung einer Hauptschlüsselanlage anhand eines Hauptschließzylinders.The invention aims to enable the installation of tumbler plates in a previously assembled locking cylinder, so that it is possible to produce and store complete locking cylinders without tumbler plates and to install the tumbler plates only in the final stage, i. H. shortly before replacing the defective locking cylinder or when assembling a master key system using a master locking cylinder.
Zu diesem Zweck ist der erfindungsgemäße Schließzylinder dadurch gekennzeichnet, daß der Zylinderkern Halterungsmittel für die Federn umfaßt, der Zylinderkern zusammen mit den Federn in das Zylindergehäuse montiert wird, und das Zylindergehäuse ein Fenster zum späteren Einsetzen der Zuhaltungsplättchen in den Zylinderkern aufweist.For this purpose, the locking cylinder according to the invention is characterized in that the cylinder core comprises holding means for the springs, the cylinder core is mounted together with the springs in the cylinder housing, and the cylinder housing has a window for later insertion of the tumbler plates in the cylinder core.
Somit wird im Gegensatz zum üblichen Herstellungsverfahren für Schließzylinder mit Plättchenzuhaltungen der Zylinderkern vor Einbau der Plättchen in das Zylindergehäuse eingesetzt und werden dann die Federn und sonstigen Zubehörteile in den vormontierten Zusammenbau aus Gehäuse und Kern montiert, worauf die auf diese Weise hergestellte Baugruppe ohne Plättchen auf Lager genommen werden kann, bevor sie nach Einbau der richtigen Plättchen in Abhängigkeit vom Hauptschließzylinder, dem sie zugeordnet werden soll, zum Einsatz kommt.In contrast to the usual manufacturing process for cylinder locks with plate tumblers, the cylinder core is used before the plates are installed in the cylinder housing and the springs and other accessories are then assembled in the pre-assembled assembly of the housing and core, whereupon the assembly produced in this way without plates is in stock can be taken before it is used after installing the correct plates depending on the master lock cylinder to which it is to be assigned.
Es ist zwar ein Schließzylinder mit Stiftzuhaltungen bekannt (FR-A 2 232 947), der ohne Stifte und Federn vormontiert wird. In diesem bekannten Schließzylinder werden nicht nur die Stifte, sondern auch die Federn später bei in das' Zylindergehäuse montiertem Zylinderkern eingeschoben, wenn der Schließzylinder für eine bestimmte Stiftanordnung benötigt wird. Im Gegensatz zu der Erfindung können die Federn erst bei der Endmontage in den Schließzylinder eingesetzt werden.A lock cylinder with pin tumblers is known (FR-A 2 232 947), which is preassembled without pins and springs. In this known locking cylinder, not only the pins, but also the springs are later inserted when the cylinder core is mounted in the cylinder housing when the locking cylinder is required for a specific pin arrangement. In contrast to the invention, the springs can only be used in the locking cylinder during final assembly.
Zum besseren Verständnis der Erfindung wird Bezug genommen auf die beigehefteten Zeichnungen, in denen
Abbildung 1 eine Draufsicht eines erfindungsgemäßen Schließzylinders mit Schließbart vor Einbau der Zuhaltungsplättchen darstellt ;Abbildung 2 ist eine Ansicht des Schließzylinders in Abb. 1 im Querschnitt ;Abbildung 3 und Abbildung 4 stellen in größerem Maßstab und im Schnitt zwei Varianten eines Zylinderkerndetails des Schließzylinders derAbbildungen 1 und 2 dar.
- Figure 1 shows a plan view of a lock cylinder according to the invention with a lock bit before installing the tumbler plate;
- Figure 2 is a cross-sectional view of the lock cylinder in Figure 1;
- Figures 3 and 4 show two variants of a cylinder core detail of the locking cylinder of Figures 1 and 2 on a larger scale and on average.
Der Schließzylinder umfaßt ein Zylindergehäuse 1 mit einem Fenster 2 zum Einbau der Zuhaltungsplättchen (nicht dargestellt) und weist eine Längsbohrung 3 auf. Ein Zylinderkern 4, wersehen mit Schlitzen 5 für die Zuhaltungsplättchen ist drehbar in der Bohrung 3 untergebracht und trägt einen Schließbart zum Betätigen eines Schlosses. In der in den Zeiohnungen dargestellten relativen Winkelstellung münden die Schlitze 5 in das Fenster 3, und die Federn 7 der Zuhaltungsplättchen sind in den Zylinderkern 4 eingesetzt und werden dort durch Halterungsmittel an Ort und Stelle gehalten. Ein Deckel 8 deckt den Kopf des Zylinderkerns 4 und das Ende des Zylindergehäuses 1 ab und gibt den Weg zum Schlüsselkanal 9 des Zylinderkerns frei. Die so vormontierte Baugruppe kann nach Belieben gehandhabt und gelagert werden, bevor sie nach Einbau der Plättchen, die den Zylinderkern 4 in bekannter Weise zuhalten können, und Schließen des Fensters 2 durch ein Verschlußorgan (nicht gezeigt), wie z. B. eine Schiebeklappe, eingefaßt oder angeschweißt, deren Einsatz aber nicht unabdingbar ist, einer Hauptschlüsselanlage zugeordnet wird.The locking cylinder comprises a
Im Schlitz 5 kann die Feder 7 durch eine Fassung 10 (Abb.3) am Eingang ihres Sitzes, durch eine Zentralhalterung 11 (Abb. 4), die beim Gießen des Zylinderkerns angeformt wird, oder durch jedes andere bekannte Mittel so gehalten werden, daß sie aus der vormontierten Baugruppe nicht herausfallen kann.In the
