Die Erfindung bezieht sich auf eine Schlauchkupplung nach dem Oberbegriff des Schutzanspruchs 1.The invention relates to a hose coupling according to the preamble of claim 1.
Solche Kupplungen sind in geschlossener Stellung nicht gegen unbeabsichtigtes Drehen und damit öffnen gesichert, so daß beiffi Be- und Entladen von Silo·" oder Tankfahrzeugen sgf» gefährliche Fördergüter, die Granulate, Pulver oder Flüssigkeiten sein können, bei ungewolltem Verdrehen der KupplungsbehSIier austreten können, z.B. aufgrund von Vibrs; ionen oder bei verdreht?": Schlauch.Such couplings are not secured against unintentional turning and thus opening in the closed position, so that when loading and unloading silos or tank vehicles, so-called dangerous goods, which can be granules, powders or liquids, can escape if the coupling is unintentionally turned, e.g. due to vibrations or if the hose is twisted.
Der Erfindung liegt die Aufgabe zugrunde, für solche Schlauchkupplungen, d.h. sogenannte "Stortz-Kupplungen" nach DIN-Norm, eine Verdrehsicherung v^r>uiehen, die leicht zu betätigen ist.The invention is based on the task of providing an anti-twisting device for such hose couplings, i.e. so-called "Stortz couplings" according to DIN standards, which is easy to operate.
Diese Aufgabe li'rd erfindungsgemäß durch die Kennzeichnungsmerkmale des Schutzanspruchs 1 gelöst. Zweckmäßige Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche,,This object is achieved according to the invention by the characterizing features of claim 1. Appropriate further developments of the invention are the subject of the subclaims,,
Die erfindungsgemäße Sicherung für Schlauchkupplungen erfordert nur wenig Aufwand im Vergleich zu ihrem Nutzen und kann Leicht betätigt werden.The safety device for hose couplings according to the invention requires little effort compared to its benefit and can be easily operated.
In der Zeichnung ist ein Ausführungsbeispiel einer erfindungsgemäßen Schlauchkupplung dargestellt. Dabei zeigtThe drawing shows an embodiment of a hose coupling according to the invention.

Fig. U eine Ansicht in Richtung des Pfeiles IV in Fig. und Fig. 3.Fig. U is a view in the direction of arrow IV in Fig. and Fig. 3.
In den Figuren 1 bis 4 ist jeweils eine Kupplungshälfte der Schlauchkupplung dargestellt^ allerdings ohne Schlauch, der in der üblichen Weise an der Kupplungshälfte 1 befestigt ist, die hier auch ohne Dichtungsringe dargestellt ist. An einer Seite der Kupplungshälfte 1 ist ein Block 2 angeformt, in dem eine achspara I lele Bohrung 3 orgesehen ist. In dieser Bohrung 3 steht ein Sicherungsbolzen 4 unter der Einwirkung einer Feder 5, die das Bestreben hat, den Sicherungsbolzen nach innen in eine Innennut 6 zu drücken, in der Kupplungsklauen 8 (Tig. 1) der jeweils anderen Kuppl u/.gshä I f t e (nicht dargestellt) eingreifen, die über Ausnehmungen 7 in einen Rand 9 der Kupplungshälfte 1 eingeführt und bis zu einem Anschlag gedreht werden.In Figures 1 to 4, one coupling half of the hose coupling is shown, but without a hose, which is attached in the usual way to the coupling half 1, which is also shown here without sealing rings. On one side of the coupling half 1, a block 2 is formed, in which an axially parallel bore 3 is provided. In this bore 3, a locking bolt 4 is under the influence of a spring 5, which tends to press the locking bolt inwards into an inner groove 6, in which coupling claws 8 (Fig. 1) of the other coupling half (not shown) engage, which are inserted via recesses 7 into an edge 9 of the coupling half 1 and rotated up to a stop.
Der Sicherungsbolzen 4 ist in der Bohrung der Kupplungshälfte 1 verschiebbar und schwenkbar gelagert, und zwar in einer fest in die Bohrung 3 eingesetzten Buchse 10 einerseits und mit der Außenzy Iinderflache einer Hülse 11 andererseits, die fest auf das innere Ende des Sicherungsbolzens 4 aufgesetzt ist. Zwischen der Buchse 10 und der Hülse 11 ist die Feder 5 abgestützt. Der Sicherungsbolzen 4 ist zu einem Betätigungshebel 12 abgewinkelt, der bei Drehung über eine am Block 2 angeformte Schrägfläche 13 gleitet, wobei er in der einen Drehrichtung den Sicherungsbolzen 4 aus dem Weg der Kupplungsklauen 8 herauszieht (Stellung 4' in den Fig. 1, 3 und 4) und in der anderen DrehMchtung den Sicherungsbolzen 4 unter Mitwirkung der feder 5 ir. die Innennut 6 der Kupplungshäl f te 1 hineinbewegt (Stellung 4" in den Fig. 1, 2 und 4), wobei der Sicherungsbolzen 4 hinter die angrenzende KupplungskLaue 8 greift, so daß die Kupplungshälften sich nicht mehr gegeneinander verdrehen können.The locking bolt 4 is mounted in the bore of the coupling half 1 so that it can move and pivot, namely in a bushing 10 firmly inserted into the bore 3 on the one hand and with the outer cylindrical surface of a sleeve 11 on the other hand, which is firmly placed on the inner end of the locking bolt 4. The spring 5 is supported between the bushing 10 and the sleeve 11. The locking bolt 4 is angled to an actuating lever 12, which slides over an inclined surface 13 formed on the block 2 when rotated, whereby in one direction of rotation it pulls the locking bolt 4 out of the way of the coupling claws 8 (position 4' in Figs. 1, 3 and 4) and in the other direction of rotation moves the locking bolt 4 into the inner groove 6 of the coupling half 1 with the help of the spring 5 (position 4" in Figs. 1, 2 and 4), whereby the locking bolt 4 engages behind the adjacent coupling claw 8 so that the coupling halves can no longer rotate against each other.
