Nummfci. 1251112Nummfci. 1251112
Die Erfindung betrifft eine lösbare Befestigung eines Schlauches auf einer Tülle, die sich in ihrem Durchmesser zu einem zylindrischen Ende hin verjüngt Und auf die eine Hülse vom Ende her aufgeschraubt ist, die dem sich verjüngenden Teil der Tülle gegenüberliegend mit einer Ausnehmung versehen ist, deren Durchmesser größer als der ihrer dem zylindrischen Tüllenende gegenüberliegenden Bohrung ist und die das auf die Tülle aufgeschobene Schlauchende im Bereich des sich verjüngenden Teils der Tülle gegen diese preßt.The invention relates to a releasable fastening of a hose on a grommet, which is in its Diameter tapers towards a cylindrical end and screwed onto one sleeve from the end is provided with a recess opposite the tapered part of the grommet whose diameter is greater than that of its opposite the cylindrical nozzle end The bore is and the hose end pushed onto the spout in the area of the tapered part the spout presses against it.
Es ist bereits eine derartige lösbare Befestigung eines Schlauches auf einer Tülle bekannt, bei der sich die Tülle konisch zu ihrem zylindrischen Ende hin verjüngt. Der Schlauch ist bis auf den konischen Teil ts der Tülle aufgeschoben. Das Schlauchende wird von einer Hülse umschlossen, deren zum Schlauchende hin liegende innere Kante stufig ausgebildet ist. Die Hülse wird von einer Überwurfmutter in Richtung des Schlauchendes gezogen, so daß die Hülse das ao Schlauchende gegen den sich konisch erweiternden Teil der Tülle preßt. Diese bekannte lösbare Befestigung eines Schlauches auf einer Tülle hat den Nachteil, daß die konische, vom Schlauchende weg sich verjüngende Fläche der Tülle praktisch kaum in der as Lage ist, größeren Zugkräften an dem Schlauch wesentlichen Widerstand entgegenzusetzen. Es besteht die größe Gefahr, daß der Schlauch einfach aus dem Zwischenraum zwischen der konischen Fläche und der anpressenden Fläche der Hülse weggezogen wird, und dies um so mehr, als bei Zugkräften eine Querschnittsverringerung des Schlauches eintritt. Nach Auftreten der Querschnittsverringerung Verschwinden die Haltekräfte fast plötzlich. Der in ün-' erwünschter Weise zum Lösen der Befestigung führende Vorgang wird noch dadurch unterstützt, daß die bei entsprechendem elastischem Material des Schlauches sich ergebenden Umfangskräfte eine Kraftkomponente in Lösungsrichtung erzeugen.Such a releasable fastening of a hose on a grommet is already known, in which the grommet tapers conically towards its cylindrical end. The hose is pushed onto the conical part ts of the nozzle. The end of the hose is enclosed by a sleeve, the inner edge of which is stepped towards the end of the hose. The sleeve is pulled by a union nut in the direction of the hose end, so that the sleeve presses the hose end against the conically widening part of the spout. This known releasable fastening of a hose on a spout has the disadvantage that the conical surface of the spout, which tapers away from the hose end, is practically hardly able to offer substantial resistance to greater tensile forces on the hose. There is a great risk that the hose will simply be pulled away from the space between the conical surface and the pressing surface of the sleeve, all the more so as a reduction in the cross section of the hose occurs under tensile forces. After the reduction in cross-section occurs, the holding forces disappear almost suddenly. The process leading to the loosening of the fastening in the desired manner is further supported by the fact that the circumferential forces resulting from the corresponding elastic material of the hose generate a force component in the direction of the loosening.
Der Erfindung liegt die Aufgabe zugrunde, bei einer lösbaren Befestigung eines Schlauches auf einer Tülle der eingangs genannten Art die Halterung oder Befestigung im Bereich des sich verjüngenden Tüllenteils zu verbessern. . >The invention is based on the problem of a detachable fastening of a hose on a Grommet of the type mentioned at the beginning, the holder or fastening in the area of the tapered grommet part to improve. . >
DiederErfindungzugrundeliegendeAufgabewird dadurch gelöst, daß die Tülle in wenigstens einer Stufe sich verjüngt. Auf diese Weise wird erreicht, daß die innere Schlauchschicht an den Stufenkanten besonders stramm anliegt, so daß sich örtliche Bezirke mit sehr hoher Anpressung und damit sehr hoher Haltewirkung ergeben.The object on which the invention is based is achieved in that the grommet is in at least one Stage tapers off. In this way it is achieved that the inner tube layer at the step edges particularly tight, so that local districts with very high pressure and thus very result in high holding effect.

einer Weiterbildung noch dadurch verbessert, daß die Hülse auf der dem zylindrischen Tüllenende gegeil·- überliegenden Bohruiigswänd mit gewindeartig verlaufenden sägezahnartigen Rillen und Vorsprüiigea versehen ist. Die sägezahnartigen Rillen greifen an die Außenfläche des Endes des Schlauches an und ziehen dieses zusätzlich gegen den sich stufenförmig verjüngenden Tüllenteil. Durch diese zusätzliche Haltewirkurtg wird außerdem die Gefahr verringert, daß im Bereich der eigentlichen Haltezone, d. h. im Bereich des sich stufenförmig verjüngenden Teils, eine Querschnittsverringerung durch Wegziehen des Schlauchmaterials eintreten kann.a further development is further improved by the fact that the sleeve on the cylindrical nozzle end is horny. overlying Bohruiigswänd with thread-like running sawtooth-like grooves and Vorsprüiig a is provided. The sawtooth-like grooves engage the outer surface of the end of the hose and pull this additionally against the step-shaped tapered sleeve part. Through this additional Haltewirkurtg is also reduced the risk that in the area of the actual holding zone, d. H. in the Area of the stepped tapering part, a cross-section reduction by pulling away the Tubing material can occur.
An Hand eines in der Zeichnung dargestellten Ausführungsbeispiels soll die Erfindung näher erläutert werden.The invention is to be explained in more detail using an exemplary embodiment shown in the drawing will.

ist, und
Fig. 2 zeigt vergrößert eine Einzelheit von Fig. 1. Ein zu befestigender Schlauch enthält eine äußere
Schichtl aus flexiblem Material wie z.B. Gummi. Unterhalb dieser Schicht befindet sich eine Verstärkungseinlage
m aus einer oder mehreren Schichten von z.B. wendelig gelegtem Draht, und dann folgt
nach innen wiederum eine Schicht k aus Gummi. Vor dem Anbringen einer erfindungsgemäßen Befestigung
ist am. Schlauchende die äußere Schichtl entfernt und die Verstärkungseinlage m freigelegt.Fig. 1 shows in cross section a hose end to which a releasable fastening according to the invention is attached, and
Fig. 2 shows an enlarged detail of Fig. 1. A hose to be fastened contains an outer layer of flexible material such as rubber. Underneath this layer there is a reinforcement insert m made of one or more layers of, for example, helically laid wire, and then another layer k made of rubber follows inwardly. Before attaching a fastening according to the invention, the outer layer 1 is removed from the hose end and the reinforcement insert m is exposed.
