Abstract

The kit for the assembly of cylinder locks has circular cylinder housing sections (2b,3b) with a shorter axial length over part of the lower circumference of the cylinder core (1), towards the cut-back portion of the centre section (7) which is U-shaped on a side view. The two legs (7a,7b) at the side of the opening for the lock bit have a bayonet locking action with the radial web housing sections (2a,3a). The free ends of the legs (7a,7b) of the centre section (7) grip the cut-back sections of the circular cylinder housing sections (2b,3b), round the cylinder core, in a force and positive fit, and wholly complete the circular cylinder housing.

Description

Die Erfindung betrifft ein Baukastensystem zur Zusammenstellung von Schließzylindern.The invention relates to a modular system for the assembly of locking cylinders.

Für unterschiedliche Einbauabmessungen werden in der Praxis beispielsweise häufig Doppelschließzylinder mit unterschiedlich langen Schließzylindern benötigt. Beispiele hierfür sind Abmessungen wie 50/50 oder 30/70 usw. Bestehen die Doppelschließzylinder aus einem zusammenhängenden Gehäuse, so muß dies bei der Fertigung berücksichtigt werden, d.h. bezogen auf die Gesamtlänge des spanend zu bearbeitenden Zylindergehäuses wird der mittlere Bereich, der später den Schließbart und die Kupplung aufnimmt, asymmetrisch angeordnet. Für jede Variante sind daher gesonderte Rohteile notwendig.
Wesentlich produktionsgünstiger wäre die Herstellung einzelner Schließzylinder und die spätere Zusammenstellung in der Art eines Baukastens.
Eine derartige Lösung ist bereits mit der EP 0 505 032 A1 vorgeschlagen worden. Hierbei wird der Doppelschhließzylinder im wesentlichen aus drei Bauteilen zusammengesetzt, und zwar den beiden die jeweiligen Zylinderkerne aufnehmenden Gehäuseteilen, und einem Mittelteil, daß in diesem Fall den Kupplungsteil und den Schließbart enthält. Die die Zylinderkerne aufnehmenden Gehäuseteile können gleich oder ungleiche Längen aufweisen.Darüberhinaus sit auch vorgesehen, daß die Mittelteile durch Zwischenstücke mit unterschiedlichen Längen ausgebildet sein können. Zur kraftschlüssigen Verbindung des Mittelteiles mit den Gehäuseteilen weisen die Steggehäuseteile Vorsprünge auf, die mit Hinterschneidungen bzw. Vorsprüngen am Mittelteil kraft- und formschlüssig in Eingriff bringbar sind. Da diese Verbindung im wesentlichen sich auf den unteren Bereich der Steggehäuseteile beschränkt, ist die Festigkeit des Doppelschließzylinders geringer im Vergleich zu einteiligen Ausführungen.In practice, double locking cylinders with locking cylinders of different lengths are often required for different installation dimensions. Examples of this are dimensions such as 50/50 or 30/70 etc. If the double lock cylinders consist of a coherent housing, this must be taken into account during production, ie based on the total length of the cylinder housing to be machined, the middle area, which later becomes the lock bit and receives the clutch, arranged asymmetrically. Separate raw parts are therefore necessary for each variant.
The production of individual locking cylinders and the later assembly in the manner of a modular system would be significantly more productive.
Such a solution has already been proposed in EP 0 505 032 A1. Here, the double locking cylinder is essentially composed of three components, namely the two housing parts receiving the respective cylinder cores, and a central part, which in this case contains the coupling part and the lock bit. The housing parts receiving the cylinder cores can have the same or different lengths. In addition, it is also provided that the middle parts can be formed by intermediate pieces with different lengths. For the non-positive connection of the middle part to the housing parts, the web housing parts have projections which can be brought into engagement with undercuts or projections on the middle part in a non-positive and positive manner. Since this connection is essentially limited to the lower area of the web housing parts, the strength of the double locking cylinder is lower compared to one-piece designs.

Der Erfindung liegt die Aufgabe zugrunde ein Baukastensystem zur Zusammenstellung von Doppelschließzylindern vorzuschlagen, daß Doppelschließzylinder ergibt, deren Festigkeit gegen axiale Krafteinwirkungen verbessert ist, bei einer Minimierung der Baukastenteile. Gelöst wird diese Aufgabe erfindungsgemäß mit den Merkmalen des Anspruchs 1. Vorzugsweise Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention has for its object a modular system for compiling Propose double lock cylinders that double lock cylinders gives their strength against axial forces is improved, while minimizing the modular parts. This object is achieved according to the invention with the features of claim 1. Refinements preferably result from the subclaims.

Kern der erfindungsgemäßen Lösung ist die besondere Ausbildung des Mittelteiles und dessen kraft- und formschlüssige Verbindung mit den Steggehäuseteilen.
Hierzu ist vorgesehen, daß dieses Mittelteile nicht nur bajonettartig mit den Steggehäuseteilen verbunden wird, sondern das auch eine kraft- und formschlüssige Verbindung des Mittelteiles mit Bereichen der Kreiszylindergehäuseteile geschaffen wird, um damit die Axialkraftaufnahmemöglichkeit zu erhöhen. Dabei greifen die freien Enden der Schenkel des Mittelteiles kraft-und formshlüssig in die jeweils angrenzenden Kreiszylindergehäuseteile ein, und zwar im unteren Bereich des die Zylinderkerne aufnehmenden Kreiszylindergehäuses.
Obwohl die Schenkel des Mittelteiles mit den Steggehäuseteilen ebenfalls kraft- und formschlüssig verbunden sind ermöglicht es gerade die Art der Verbindung, nämlich die bajonettartige Verbindung, ohne wesentlich Materialschwächung noch in dem umgriffenen Bereich Zuhaltungen im Steggehäuseteil vorzusehen, so daß die Anzahl der Zuhaltungen nicht verringert werden mußte. Dies trägt zur Sicherheit ebenfalls bei.The core of the solution according to the invention is the special design of the middle part and its non-positive and positive connection with the web housing parts.
For this purpose, it is provided that this central part is not only connected bayonet-like to the web housing parts, but also that a non-positive and positive connection of the central part to regions of the circular cylinder housing parts is created, so as to increase the possibility of absorbing axial forces. The free ends of the legs of the middle part engage in a force-fitting and form-fitting manner in the respectively adjacent circular cylinder housing parts, specifically in the lower region of the circular cylinder housing receiving the cylinder cores.
Although the legs of the middle part are also non-positively and positively connected to the web housing parts, it is precisely the type of connection, namely the bayonet-type connection, which allows the locking of the web housing part without significant material weakening in the encompassed area, so that the number of tumblers is not reduced had to. This also contributes to security.

Different types of connection between the bar housing and the middle section.

Der Doppelschließzylinder besteht aus zwei Kreiszylindergehäuseteilen 2b und 3b mit den darin angeordneten Zylinderkernen 1. Radial abgehend von den Kreiszylindergehäuseteilen befindet sich jeweils das Steggehäuseteil 2a und 3a. Das Mittelteil 7 weist eine Ausnehmung 4 auf für einen hier nicht dargestellten Schließbart und eine Bohrung 6 für die Aufnahme der Stulpschraube.Das Mittelteil ist U-förmig ausgebildet, wie dies aus den Zeichnungen ersichtlich ist. Ebenfalls ergibt sich aus den Zeichnungen die Ausbildung der Schenkel des Mittelteiles 7.lm Stegbereich sind die Schenkel 7a,7b mit Hinterschneidungen ausgebildet, die mit entsprechenden Hinterschneidungen an den dem Mittelteil zugewandten Bereichen der Steggehäuseteile, dies teilweise umklammernd, in Eingriff bringbar sind. Aus der Figur 2 ist nun ein sehr wesentliches Merkmal der erfindunggemäßen Lösung zu ersehen. Die freien Enden der Schenkel haben nämlich teilweise die Form des unteren Bereiches des Kreiszylindergehäuses und sind so ausgebildet, daß sie mit diesem kraft- und formschlüssig verbindbar sind. Damit kommt diese Verbindung nicht nur im unteren Bereich der Steggehäuseteile zustande, sondern auch im Bereich der Kreiszylindergehäuseteile. Hier wird der ausgesparte oder zurückspringende Teil des Gehäuses mit für die Verbindung ausgenutzt, so daß die Gesamtfestigkeit wesentlich verbessert wurde.
Die Verbindung des Mittelteiles 7 mit den Steggehäuseteilen 2a und 3a kann in verschiedener Weise erfolgen, wobei sichergestellt sein muß, daß die Verbindung auch kraftschlüssig ist.
Beispielsweise kann hierzu im unteren Bereich des einen Steggehäuseteiles eine Bohrung 8 für einen Raststift 9 vorgesehen sein (Fig.3), der federbelastet in eine Bohrung im Mittelteil einrasten kann.
Ferner können auch an den Schenkeln 7a,7b und entsprechend an den zugewandten Steggehäuseteilen 2a,3a Senkungen 10 ( Fig.4,5) vorhanden sein, in die eine Art Sicherungsringe 11 eingeschoben werden oder aber verdrehbare Rastscheiben 13 ( Fig.8). Eine weitere Möglichkeit wäre ein Haltebügel 12 (Fig. 6,7,9,10), der über die
Kreiszylindergehäuseteile gestülpt, mit den Schenkeln des Mittelteiles in Eingriff bringbar ist. Die Fixierung an den Schenkeln könnte dabei durch Formschluß oder über Sicherungsstifte erfolgen.
Schließlich kann eine Verbindung des Mittelteiles mit den Steggehäuseteilen auch durch Sicherungsstifte oder -schrauben 14 (Fig. 11,12) erfolgen, die in Bohrungen eingesetzt werden, die durch die Schenkel in die Steggehäuseteile reichen.The double lock cylinder consists of two circular cylinder housing parts 2b and 3b with the cylinder cores 1 arranged therein. The web housing parts 2a and 3a are located radially starting from the circular cylinder housing parts. The middle part 7 has a recess 4 for a lock bit not shown here and a bore 6 for receiving the faceplate screw. The middle part is U-shaped, as can be seen from the drawings. The drawings also show the formation of the legs of the middle part 7. In the web area, the legs 7a, 7b are formed with undercuts, which can be brought into engagement with corresponding undercuts on the areas of the web housing parts facing the middle part, this partially clasping them. A very essential feature of the solution according to the invention can now be seen from FIG. The free ends of the legs have in part the shape of the lower region of the circular cylinder housing and are designed in such a way that they can be connected to the latter in a non-positive and positive manner. This connection is thus established not only in the lower area of the web housing parts, but also in the area of the circular cylinder housing parts. Here, the recessed or recessed part of the housing is also used for the connection, so that the overall strength has been significantly improved.
The connection of the middle part 7 with the web housing parts 2a and 3a can take place in different ways, whereby it must be ensured that the connection is also non-positive.
For example, a bore 8 for a locking pin 9 can be provided for this purpose in the lower region of one web housing part (FIG. 3), which can snap into a bore in the central part in a spring-loaded manner.
In addition, countersinks 10 (FIG. 4, 5) can also be provided on the legs 7 a, 7 b and correspondingly on the facing web housing parts 2 a, 3 a, into which a type of locking rings 11 are inserted or rotatable locking disks 13 (FIG. 8). Another possibility would be a bracket 12 (Fig. 6,7,9,10), which over the
Circular cylinder housing parts turned over, can be brought into engagement with the legs of the central part. The fixation on the legs could be done by positive locking or locking pins.
Finally, the middle part can also be connected to the web housing parts by means of locking pins or screws 14 (FIGS. 11, 12) which are inserted into bores which extend through the legs into the web housing parts.
