Abstract

The stop nose formation ring parts (1,2) in the ring area (3) have a link securing device (4), which extends longitudinally. The parts in the area of the stop nose formation are divided crossways, so that the two stop nose formation ring parts form the complete stop nose formation. The link securing device is formed by a longitudinally running securing groove (5) on a closure nose formation ring part (1), and a securing rib (6) of the other closure nose formation ring part which engages in it. The securing groove is back-cut allowing the securing rib to engage in it. The two stop nose formation parts (13,14) can be secured to one another.

Description

Die Erfindung betrifft einen Schließzylinder mit einem eine Sperrnase tragenden zweigeteilten Sperrnasenring, wobei die Sperrnasenringteile durch Befestigungsmittel unter Ausbildung des geschlossenen Sperrnasenringes miteinander fixierbar sind.The invention relates to a lock cylinder with a two-part locking nose ring carrying a locking nose, the locking nose ring parts being fixable to one another by fastening means to form the closed locking nose ring.

Ein derartiger Schließzylinder ist beispielsweise aus der ÖP-390 469 bekannt geworden. Der Sperrnasenring ist dabei längsgeteilt, und im Bereich der Sperrnase ist ein Gelenk vorgesehen, um das die Sperrnasenringteile bei der Montage geschwenkt und zusammengefügt werden können. Auf der anderen Seite stoßen die Sperrnasenringteile im ringförmigen Abschnitt stumpf aufeinander und zur Befestigung muß eine Federklammer vorgesehen werden.Such a locking cylinder has become known, for example, from ÖP-390 469. The locking nose ring is longitudinally divided, and a joint is provided in the area of the locking nose, around which the locking nose ring parts can be pivoted and assembled during assembly. On the other hand, the locking nose ring parts butt in the annular section butt and a spring clip must be provided for attachment.

In der Praxis hat sich gezeigt, daß diese Federklammer nachteilig ist. Bei nicht sogfältiger Montage kann es vorkommen, daß die Federklammer abspringt und das Schloß unbrauchbar wird. Überdies ist die bekannte Konstruktion teuer in der Herstellung.In practice it has been shown that this spring clip is disadvantageous. If the assembly is not careful, it may happen that the spring clip springs off and the lock becomes unusable. In addition, the known construction is expensive to manufacture.

Aufgabe der vorliegenden Erfindung ist es, einen verbesserten Sperrnasenring vorzusehen, der die genannten Nachteile nicht aufweist. Darüberhinaus soll die Montage erleichert und die Herstellung verbilligt werden.The object of the present invention is to provide an improved locking nose ring which does not have the disadvantages mentioned. In addition, the assembly should be made easier and the production should be cheaper.

Der erfindungsgemäße Schließzylinder ist dadurch gekennzeichnet, daß die Sperrnasenringteile im Ringbereich eine Gelenkraste aufweisen, die sich in Längsrichtung erstreckt, und daß die Sperrnasenringteile im Bereich der Sperrnase quer geteilt sind, sodaß sich die beiden Sperrnasenteile zur fertigen Sperrnase ergänzen.The locking cylinder according to the invention is characterized in that the locking nose ring parts have an articulated catch in the ring area which extends in the longitudinal direction, and that the locking nose ring parts are divided transversely in the area of the locking nose, so that the two locking nose parts complement each other to form the finished locking nose.

Weitere Merkmale der Erfindung sind den Patentansprüchen, der nachfolgenden Beschreibung und den Zeichnungen zu entnehmen.Further features of the invention are the patent claims, the following description and the drawings.

Die Figuren 1 bis 3 zeigen die Seitenansicht des Sperrnasenringes in drei verschiedenen Montagestellungen. Fig. 4 zeigt die Ansicht der beiden auseinandergeklappten Sperrnasenringteile.Figures 1 to 3 show the side view of the locking nose ring in three different mounting positions. Fig. 4 shows the view of the two unfolded locking nose ring parts.

Die grundsätzliche Konstruktion und Wirkungsweise eines Sperrnasenringes in einem Schließzylinder, insbesondere einem Doppelschließzylinder, ist seit langem Stand der Technik und wird hier nicht weiter erläutert. Auch diesbezüglich wird auf das ÖP 390 469 verwiesen. Bei einem Doppelschließzylinder befindet sich der Sperrnasenring zwischen den beiden Halbzylindern. Je nachdem, von welcher Seite der Schlüssel eingesteckt und das Schloß betätigt wird, kann über eine Kupplung der Sperrnasenring mit einem der beiden Zylinderkerne auf Drehung gekuppelt werden. Die Drehbewegung des Sperrnasenringes bewirkt das Mitverdrehen der Sperrnase, die radial aus dem Schloßgehäuse hervorragt und Betätigungselemente des zugehörigen Türschlosses betätigt.The basic construction and mode of operation of a locking nose ring in a locking cylinder, in particular a double locking cylinder, has long been state of the art and is not further explained here. In this regard, too, reference is made to ÖP 390 469. In the case of a double lock cylinder, the locking nose ring is located between the two half cylinders. Depending on which side the key is inserted and the lock is actuated, the locking ring can be coupled to one of the two cylinder cores for rotation via a coupling. The rotary movement of the locking nose ring causes the locking nose to also rotate, which projects radially from the lock housing and actuates actuating elements of the associated door lock.

Der in den Figuren dargestellte Sperrnasenring ist von jener Art, bei der die beiden Zylinderkerne durch Verklauung gegen Abziehen gesichert sind. Auch dies ist Stand der Technik z.B. gemäß ÖP 390 469.The locking nose ring shown in the figures is of the type in which the two cylinder cores are secured against being pulled off by clawing. This is also state of the art e.g. according to ÖP 390 469.

Der Sperrnasenring ist durch zwei Sperrnasenringteile 1 und 2 gebildet. Beide Sperrnasenringteile haben im wesentlichen die gleichen Abmessungen, sodaß sie aus einem einzigen Profil gefertigt werden können. Die fertigen Sperrnasenringteile können aus den Profilteilen durch entsprechende Nachbearbeitung, wie Räumen und Fräsen gefertigt werden.The locking nose ring is formed by two locking nose ring parts 1 and 2. Both locking nose ring parts have essentially the same dimensions, so that they can be manufactured from a single profile. The finished locking nose ring parts can be made from the profile parts by appropriate post-processing, such as broaching and milling.

Im Ringbereich 3 weisen die Sperrnasenringteile eine Gelenkraste 4 auf, die sich in Längsrichtung des Sperrnasenringes erstreckt. Längsrichtung bedeutet hier die Längrichtung des Schlosses.In the ring area 3, the locking nose ring parts have an articulated catch 4, which extends in the longitudinal direction of the locking nose ring. Longitudinal direction here means the longitudinal direction of the castle.

Die Gelenkraste ist dadurch gebildet, daß an dem einen Schließnasenringteil 1 eine Rastnut 5 verläuft, und der andere Schließnasenringteil 2 mit einem Raststeg 6 versehen ist, der in die Rastnut 5 eingreift. Die Rastnut 5 ist bevorzugt hinterschnitten und der Raststeg 6 greift in die Hinterschneidung ein, sodaß die Verbindung in montiertem Zustand (gemäß Fig. 3) festhält.The articulated catch is formed in that a locking groove 5 extends on the one locking ring part 1 and the other locking ring part 2 is provided with a locking web 6 which engages in the locking groove 5. The locking groove 5 is preferably undercut and the locking web 6 engages in the undercut, so that the connection holds in the assembled state (according to FIG. 3).

Nach innen ragen zwei ringförmige Verklauungstege 7, die in entsprechende Ringnuten der zugehörigen Zylinderkerne eingreifen, wodurch die beiden Zylinderkerne auch bei Anwendung hoher Zugkräfte nicht aus dem Schloss herausgezogen werden können. Die nach außen versetzte innere Ringfläche 8 ist in den Figuren 1 bis 3 strichliert eingezeichnet.Inwardly protrude two annular claw webs 7, which engage in corresponding ring grooves of the associated cylinder cores, so that the two cylinder cores cannot be pulled out of the lock even when high tensile forces are used. The outwardly displaced inner ring surface 8 is shown in broken lines in FIGS. 1 to 3.

Entlang der Teilungsebene 9 ist der Ringbereich 3 mit Anschlagflächen 10, 11 versehen, die eine exakte Ringform gewährleisten.Along the division plane 9, the ring area 3 is provided with stop faces 10, 11, which ensure an exact ring shape.

Die Sperrnasenringteile 1, 2 sind weiters im Bereich der Sperrnase 12 quergeteilt, wobei sich die beiden Sperrnasenringteile in diesem Bereich zur fertigen Sperrnase ergänzen. Die Sperrnasenteile sind in den Figuren mit den Bezugszeichen 13, 14 versehen. Zur Verrastung der Sperrnasen und festen Montage des gesamten Sperrnasenringes, dient der Raststift 15, der in die Längslöcher 16, der beiden Sperrnasenteile 13, 14 gesteckt wird, wenn die Längslöcher fluchten.The locking nose ring parts 1, 2 are further cross-divided in the area of the locking nose 12, the two locking nose ring parts in this area complementing the finished locking nose. The locking nose parts are provided with the reference numerals 13, 14 in the figures. The locking pin 15, which is inserted into the longitudinal holes 16, the two locking nose parts 13, 14 when the longitudinal holes are in alignment, is used to lock the locking lugs and firmly mount the entire locking nose ring.

Wie insbesondere in Fig. 3 zu erkennen ist, ist der eine Sperrnasenringteil 2 an seinen Verklauungsstegen 7 und der inneren Ringfläche 8 im Bereich der Sperrnase nach außen erweitert. Diese Erweiterung dient der Erleichterung der Montage.As can be seen in particular in FIG. 3, the one locking nose ring part 2 is on the outside of its locking webs 7 and the inner ring surface 8 in the region of the locking nose expanded. This extension serves to facilitate assembly.

Bei der Montage wird ausgehend von der Stellung gemäß Fig. 4 der Raststeg 6 in die Rastnut 5 eingelegt, beide Sperrnasenringteile über die inneren Enden der Zylinderkerne gelegt und der Rastring geschlossen, bis die Stellung nach Fig. 3 erreicht ist. Mit bekannten Mitteln und unter Verwendung des Rastloches 17 wird die Drehstellung der Sperrnase 12 zum Zylinderschloß eingestellt. Mittels des Raststiftes 15 werden die beiden Sperrnasenteile 13, 14 verbunden, und damit der Sperrnasenring fixiert.During assembly, starting from the position shown in FIG. 4, the locking web 6 is inserted into the locking groove 5, both locking nose ring parts are placed over the inner ends of the cylinder cores and the locking ring is closed until the position shown in FIG. 3 is reached. With known means and using the locking hole 17, the rotational position of the locking lug 12 is set to the cylinder lock. By means of the locking pin 15, the two locking nose parts 13, 14 are connected, and thus the locking nose ring is fixed.

Abänderungen der beschriebenen Konstruktion sind im Rahmen der geoffenbarten Erfindung möglich, so können z.B. die Sperrnasenteile 13, 14 verschiedene Länge (in Längsrichtung des Schlosses) aufweisen. Die Verrastung der beiden Sperrnasenringteile kann durch andere Mittel erfolgen, z.B. durch Schrauben, wenn gleich die dargestellte Konstruktion mit dem Raststift 15 besonders einfach und billig ist.Modifications to the described construction are possible within the scope of the disclosed invention, e.g. the locking nose parts 13, 14 have different lengths (in the longitudinal direction of the lock). The two locking nose ring parts can be locked by other means, e.g. by screws, if the construction shown with the locking pin 15 is particularly simple and cheap.
