Description

Befestigung eines in eine starre Hülse eingeschobenen elastischen Schlauches Die Erfindung -bezieht sich auf die Befestigung eines in eine starre Hülse, vorzugsweise aus hartem thermoplastischem Kunststoff, eingeschobenen elastischen Schlauches unter Heranziehung des in der Leitung herrschenden Druckes.Attachment of an elastic inserted into a rigid sleeve Hose The invention -refers to the attachment of one into a rigid Sleeve, preferably made of hard thermoplastic material, inserted elastic Hose using the pressure prevailing in the line.

Bei einer bekannten Befestigung dieser Art weist die Hülse eine Sicke auf, während im Schlauchende eine der Hülsensicke entsprechende Schlauchwandsicke angeordnet ist, die sich beim axialen Einschieben des Schlauches in die Hülse zunächst in radialer Richtung im Sinne einer Durchmesserverkleinerung elastisch verformt und in der Endlage durch elastische Rückverformung in ihre ursprüngliche Gestalt in die zugehörige Hülsensicke einrastet, wobei die Abmessungen der Hülsen- und der Schlauchwandsicke sowohl in radialer als auch in axialer Richtung klein sind gegen die Durchmesserabmessungen der Hülse und des Schlauches.In a known fastening of this type, the sleeve has a bead while in the end of the hose a hose wall bead corresponding to the sleeve bead is arranged, which is initially when the tube is axially pushed into the sleeve elastically deformed in the radial direction in the sense of a diameter reduction and in the end position by elastic deformation back to its original shape snaps into the associated sleeve bead, the dimensions of the sleeve and the Hose wall bead both in the radial and in the axial direction are small against the diameter dimensions of the sleeve and hose.

Die der Erfindung zugrunde liegende .'-Aufgabe besteht darin, diese vorbekannte einfache Art der Schlauchbefestigung für Wellschläuche auszunutzen.The .'- task on which the invention is based is to achieve this exploit previously known simple type of hose attachment for corrugated hoses.

Bisher wurden solche Wehschläuche entweder mit zylindrischen Enden zum Befestigen in einer Endarmatur ausgerüstet, was die Herstellung des Schlauches in Fixlängen bedingte und verteuerte, oder das Ende des Wellschlauches wurde umständlich, beispielsweise zwischen einer gegebenenfalls gesickten Tülle, deren Sicken axial größer als die Wellungen des Schlauches sind, und einer Hülse eingespannt. Nach einer weiteren bekannten Ausführungsform wurde um das mittels einer zylindrischen Tülle ausgesteifte Ende des Wellschlauches eine starre Hülse aus thermoplastischem Kunststoff herumgegossen; deren Sicken demgemäß den Konturen des Wellschlauches formgenau angepaßt sind, die aber schon bei der Fabrikation des Schlauches auf Fixlänge angebracht werden muß.So far, such inflated hoses were either with cylindrical ends equipped for fastening in an end fitting, which is the production of the hose in fixed lengths and more expensive, or the end of the corrugated hose became cumbersome, for example between an optionally corrugated grommet, the beads of which are axially larger than the corrugations of the hose, and clamped in a sleeve. To Another known embodiment was around the means of a cylindrical Grommet stiffened end of the corrugated hose a rigid sleeve made of thermoplastic Plastic molded around; whose beads correspond to the contours of the corrugated hose are adapted to the exact shape, but which are already set to a fixed length during the manufacture of the hose must be attached.

Die Lösung der der Erfindung zugrunde liegenden Aufgabe besteht darin, daß in der starren Hülse - im Axialschnitt gesehen - mehrere Sicken vorgesehen sind, in die -als Schlauchwandsicken die Wellenberge eines Wellschlauches einrasten, wobei die Hülsensicken den Konturen des Wellschlauches formgenau angepaßt sind.The solution to the problem on which the invention is based is to that in the rigid sleeve - seen in axial section - several beads are provided, into which the wave crests of a corrugated hose snap into place as hose wall beads, whereby the sleeve beads are precisely matched to the contours of the corrugated hose.

Der Vorteil gegenüber dem Bekannten liegt in der einfachen Befestigung des an beliebiger Stelle auf die erforderliche Länge abgeschnittenen Schlauches, da trotz Anwendung mehrerer Sicken in der starren Hülse ein axiales Einschieben des Wellschlauches in die starre Hülse möglich ist, was darauf zurückzuführen ist, daß ein im Blasverfahren hergestellter, in allen Teilen wandstärkengleicher Wellschlauch Anwendung findet, der nicht nur das axiale Einschieben erleichtert, sondern nachher beim Hindurchleiten des Fludes dafür sorgt, daß der in der Leitung herrschende Druck den Schlauch mit Sicherheit in den Sicken der starren Hülse festhält, so daß trotz der in allen Teilen gleichen, verhältnismäßig dünnen Wandstärke ein axiales Herausziehen des Wellschlauches infolge des inneren Flüssigkeitsdruckes nicht möglich ist.The advantage over the known lies in the simple attachment the hose cut to the required length at any point, because despite the use of several beads in the rigid sleeve, axial insertion of the corrugated hose into the rigid sleeve is possible, which is due to that a corrugated tube made in the blow molding process, with the same wall thickness in all parts It is used that not only facilitates axial insertion, but also afterwards ensures that the pressure prevailing in the line when the fluid is passed through holds the hose securely in the beads of the rigid sleeve, so that in spite of the relatively thin wall thickness, which is the same in all parts, is axially pulled out of the corrugated hose is not possible due to the internal fluid pressure.

Die Erfindung ist an Hand eines Ausführungsbeispiels erläutert. Es zeigt F i g. 1 einen Axialschnitt durch die Befestigungsstelle zwischen einer starren Hülse und einem elastischen Wellschlauch, F i g. 2 eine Ansicht der Befestigungsstelle.The invention is explained using an exemplary embodiment. It shows Fig. 1 shows an axial section through the attachment point between a rigid Sleeve and an elastic corrugated hose, F i g. 2 is a view of the attachment point.

Die Wellenberge 11 eines Wellschlauches 10 verlaufen bis zum Stirnende 9 z. B. in Form von Gewindegängen. In der Hülse 12 sind, ausgehend von dem einen Stirnende 13, an der Innenwandung 14 die Ausnehmungen 15, ebenfalls in Form von Gewindegängen, den Konturen des Wehschlauches 10 formgenau angepaßt, wodurch entsprechende Gewindewulste 16 an der Außenfläche 17 der Hülse 12 entstehen.The wave crests 11 of a corrugated hose 10 extend to the front end 9 z. B. in the form of threads. In the sleeve 12 , starting from the one end 13 on the inner wall 14, the recesses 15, also in the form of threads, are precisely matched to the contours of the inflation tube 10 , whereby corresponding thread beads 16 are formed on the outer surface 17 of the sleeve 12 .
