Abstract
Description
Die Erfindung bezieht sich auf einen Schließzylinder mit Stiftzuhaltungen, der ein Zylindergehäuse umfaßt, in dem sich ein mit Stiften versehener Zylinderkern dreht und die Stifte jeweils der Wirkung einer Rückholfeder ausgesetzt sind.The invention relates to a lock cylinder with pin tumblers, which comprises a cylinder housing in which a cylinder core provided with pins rotates and the pins are each exposed to the action of a return spring.
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. Das ist der Fall beispielsweise bei einer Hauptschlüsselanlage für Kraftfahrzeuge, zu der gehören ein Hauptschließzylinder, der als Diebstahlsicherung ausgebildet ist und mit Stiftzuhaltungen 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 Stifte und die Stiftfedern eingebaut wurden.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. This is the case, for example, with a master key system for motor vehicles, which includes a master lock cylinder that is designed as an anti-theft device and can work with pin 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 on the basis of the key for the master lock cylinder, the various lock cylinders must be manipulated in order to insert the cylinder cores into which the pins and the pin springs were previously installed.
Die Erfindung zielt darauf ab, den Einbau von Stiften in einen zuvor fertig montierten Schließzylinder zu ermöglichen, so daß es möglich ist, vollständige Schließzylinder ohne Stifte herzustellen und auf Lager zu legen und die Stifte 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 pins in a previously assembled locking cylinder, so that it is possible to manufacture and store complete locking cylinders without pins and to install the pins 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 das Zylindergehäuse ein Fenster zum Einsetzen der Stifte aufweist, der Zylinderkern Mittel zum Haltern der Stiftfedern umfaßt und die Stifte später in den Zylinderkern eingebaut werden.For this purpose, the locking cylinder according to the invention is characterized in that the cylinder housing has a window for inserting the pins, the cylinder core comprises means for holding the pin springs and the pins are later installed in the cylinder core.
Somit wird im Gegensatz zum üblichen Herstellverfahren für Schließzylinder mit Stiftzuhaltungen der Zylinderkern vor Einbau der Stifte in das Zylindergehäuse eingesetzt und werden dann die Stiftfedern und sonstigen Zubehörteile in den vormontierten Zusammenbau aus Gehäuse und Kern montiert, worauf die auf diese Weise hergestellte Baugruppe ohne Stifte auf Lager genommen werden kann, bevor sie nach Einbau der richtigen Stifte in Abhängigkeit vom Hauptschließzylinder, dem sie zugeordnet werden soll, zum Einsatz kommt.Thus, in contrast to the usual manufacturing process for locking cylinders with pin tumblers, the cylinder core is used before installing the pins in the cylinder housing and then the pin springs and other accessories are assembled in the pre-assembled assembly of the housing and core, whereupon the assembly produced in this way without pins is in stock can be taken before installing the correct pins depending on the master lock cylinder to which they are assigned should be used.

Der Schließzylinder umfaßt ein Zylindergehäuse 1 mit einem Fenster 2 zum Einbau der Stifte (nicht dargestellt) und weist eine Längsbohrung 3 auf. Ein Zylinderkern 4, versehen mit Schlitzen 5 für die Stifte, ist drehbar in der Bohrung 3 untergebracht und trägt einen Schließbart zum Betätigen eines Schlosses. In der in den Zeichnungen dargestellten relativen Winkelstellung münden die Schlitze 5 in das Fenster 3, und die Federn 7 der Stifte 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 Stifte, 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
