Description
Höchstlichtungsschlauch Die Erfindung bezieht sich auf einen Schlauch mit einem dünnen, elastisch dehnbaren Schlauchmantel aus Gummi, Kunststoff oder einem beliebigen elastischem Gewebe, der auf der Innenseite durch schraubengangförmige, zueinander parallel verlaufende, auf dem Schlauchmantelinnenumfang etwa gleichmäßig verteilt angeordnete Längsleisten beliebig steilen oder fiacheren Verlaufs ausgesteift ist.The invention relates to a hose with a thin, elastically stretchable hose jacket made of rubber, plastic or any elastic fabric, which is connected on the inside by helical, parallel to each other, approximately evenly on the inner circumference of the hose jacket Distributed longitudinal strips stiffened in any steep or flatter course is.
Bei einem bekannten Schlauch dieser Art steigt die Wandstärke der Leisten aus der Wandstärke des Schlauchmantels allmählich und kontinuierlich an, so daß bei Umfangs dehnung des Schlauches seine Dehnbarkeit in dieser Richtung von einem Maximum in der dünnen Schlauchwand zwischen den Leisten über Übergangszonen in den Leistenbereichen geringer Wandstärke zu einem Minimum in den Leistenbereichen großer Wandstärke abnimmt. Dabei verändern die Leisten ihre Querschnittsform in der Weise, daß sie an Breite zu- und an Höhe abnehmen. In a known hose of this type, the wall thickness increases Gradually and continuously adjoin the wall thickness of the hose jacket, so that with circumferential expansion of the hose its extensibility in this direction of a maximum in the thin tube wall between the strips via transition zones in the groin areas of low wall thickness to a minimum in the groin areas large wall thickness decreases. The bars change their cross-sectional shape in such that they increase in width and decrease in height.
Durch diese Querschnittsveränderung der Leisten wird der Schlauch bei Umfangsdehnung nicht gezwungen, seine größtmögliche Lichtung einzunehmen, wenn er z. B. unter Umfangsdehnung über ein Rohr gezogen wird, da der radiale Abstand der Schlauchmantelinnenfläche von der Innenrohraußenfläche kleiner ist als die Höhe der Leiste im ungedehnten Schlauch und der freie Raum zwischen den Leisten kleiner als beim ungedehnten Schlauch ist.This change in cross-section of the strips creates the hose in the case of circumferential expansion not forced to occupy its largest possible clearing, if he z. B. is drawn under circumferential expansion over a pipe, since the radial distance the inner surface of the hose jacket from the outer surface of the inner pipe is smaller than the height the bar in the unstretched tube and the free space between the bars is smaller than is the case with the unstretched hose.
Der Erfindung liegt die Aufgabe zugrunde, einen derartigen Schlauch so zu gestalten, daß er auch bei Umfangsdehnung seinen größtmöglichen freien Querschnitt zwischen den Leisten erzielt. The invention is based on the object of such a hose to be designed so that it has its largest possible free cross-section even with circumferential expansion scored between the bars.
Diese Aufgabe wird bei einem Schlauch mit einem dünnen, elastisch nachgiebigen Schlauchmantel, der auf der Innenseite durch Längsleisten ausgesteift ist, erfindungsgemäß dadurch gelöst, daß die Leisten in an sich bekannter Weise formstabil mit etwa rechteckigem Querschnitt ausgebildet sind. This task becomes with a hose with a thin, elastic flexible hose jacket stiffened on the inside by longitudinal strips is solved according to the invention in that the strips in a known manner are dimensionally stable with an approximately rectangular cross-section.
Schläuche mit einem Schlauchmantel aus Gummi oder Kunststoff, der auf der Innenseite durch achsparallel und zueinander parallel verlaufende, auf dem Schlauchmantelinnenumfang etwa gleichmäßig verteilt angeordneten, formstabilen Leisten mit etwa rechteckigem Querschnitt ausgesteift ist, sind an sich bekannt. Dabei handelt es sich aber um solche Schläuche, bei denen der Schlauchmantel kräftig ausgebildet ist und etwa auftretenden Umfangsdehnungen standhält. Das Aufziehen dieser Schläuche erfolgt auf solche Innenrohre, deren Außendurchmesser praktisch keine Umfangsdehnung der Schläuche hervorruft. Hoses with a hose jacket made of rubber or plastic, the on the inside by axially parallel and mutually parallel, on the The inner circumference of the hose jacket is roughly evenly distributed and has dimensionally stable strips is stiffened with an approximately rectangular cross-section are known per se. It acts But it is a matter of such hoses in which the hose jacket is strong and withstands any circumferential expansion that may occur. The pulling up of these tubes takes place on such inner tubes, the outer diameter of which has practically no circumferential expansion the hoses.
Erst durch die erfindungsgemäße Kombination der formstabilen, im Querschnitt etwa rechteckigen Leisten mit einem dünnen elastisch dehnbaren Schlauchmantel wird die Schlauchwand in zwei baulich und funktionell sich scharf voneinander abhebende Wandelemente gegliedert, von denen die festen Leisten statische, bei Umfangsdehnung im wesentlichen undehnbare und so in Höhe und Breite unveränderlich beharrende Teile verkörpern, während die zwischen ihnen verlaufenden Schlauchmantelteile dynamische, bei Umfangsdehnung nachgiebige bis hochelastische Wandelemente darstellen, so daß beim Aufziehen auf einen dornartigen Körper od. dgl. auch bei stärkster radialer Dehnung die zwischen den Längsleisten gebildeten Rinnen bzw. Only through the inventive combination of dimensionally stable, in cross section approximately rectangular strips with a thin, elastically stretchable hose jacket the hose wall in two structurally and functionally sharply contrasting one another Wall elements structured, of which the fixed strips are static, with circumferential expansion essentially inextensible and so unchangeable in height and width parts embody, while the hose jacket parts running between them are dynamic, represent flexible to highly elastic wall elements in the case of circumferential expansion, so that when pulling onto a thorn-like body or the like, even with the strongest radial Expansion of the grooves or grooves formed between the longitudinal strips.
Kanäle für den Durchtritt von Gasen oder müssigkeiten aufrechterhalten bleiben bzw. bei sehr dehnungsfähigem und sehr dünnem, weichem Schlauchmantelwerkstoff sogar eine Erweiterung mit wesentlichem Lichtungsgewinn erfahren und so besonders gut zu dynamischer Ansauge- oder Gebläsewirkung befähigt sind.Maintain channels for the passage of gases or wastes remain or with very stretchable and very thin, soft hose jacket material even experienced an extension with a significant gain in clearing and so special are well capable of dynamic suction or blower effects.
Zweckmäßige Ausgestaltungen des erfindungsgemäßen Schlauches sind in den Unteransprüchen gekennzeichnet. Appropriate configurations of the hose according to the invention are characterized in the subclaims.
