Abstract

The invention relates to an indirect, detachable connection for plastic and metal sections, especially plastic tubes. The aim of the invention is to produce a connection of this type which is above all, economical and can be assembled rapidly. To this end, a sleeve type connection element (1) is provided. Said connection element has at least two rod elements (2a, 2b) extending beyond each of its ends in the direction of the surface line. Said rod elements have radially inwards-pointing teeth (3) which can be pressed into the material of the section ends (5a, 5b) being connected by means of pressure rings (4a, 4b), said pressure rings being displaced by the rod elements (2a, 2b), to produce a positive and non-positive connection between the section ends and the connection element (1).

Description

Mittelbare, lösbare Verbindung für Kunststoff- und Metaiiprofile, insbesondere für Kunststoff röhreIndirect, detachable connection for plastic and metal profiles, especially for plastic tubes
Die Erfindung betrifft eine mittelbare, lösbare Verbindung für Kunststoff- und Metaiiprofile, insbesondere für Kunststoffrohre .The invention relates to an indirect, detachable connection for plastic and metal profiles, in particular for plastic pipes.
Zum dichten und zugfesten Verbinden von zwei Schlauchenden, insbesondere von Gartenschläuchen aus Gummi oder Kunststoff, ist es bekannt, ein Verbindungselement zu verwenden, mit dem eine kraft- und form schlüssige Verbindung erzielt wird. Dabei werden die Schlauchenden, die von beiden Seiten auf ein Muffenrohr aufgesteckt sind, mittels je eines Schraubringes auf das Muffenrohr gepreßt, der auf hakenartige Elemente einwirkt, die in das elastische Schlauchmaterial eindringen.For the tight and tensile connection of two hose ends, in particular garden hoses made of rubber or plastic, it is known to use a connecting element with which a non-positive and positive connection is achieved. The hose ends, which are attached to a socket pipe from both sides, are pressed onto the socket pipe by means of a screw ring each, which acts on hook-like elements that penetrate into the elastic hose material.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbindung der oben genannten Art zu schaffen, die vorallem preiswert ist und geringe Montagezeit erfordert.The invention has for its object to provide a connection of the type mentioned above, which is especially inexpensive and requires little installation time.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein muffenartges Verbindungselement, das mindestens je zwei über seine Enden in Manteilinienrichtung sich hinaus erstreckende Stangeneiemente mit radial einwärts gerichteten Zähnen aufweist, die mitteis über die Stangenelemente schiebbarer Anpressringe in das Material der zu verbindenden Profilenden eindrückbar sind und zu deren kraft- und formschlüssigen Verbindung mit dem Verbindungselement führen.This object is achieved according to the invention by a sleeve-type connecting element which has at least two rod elements with radially inwardly directed teeth extending beyond its ends in the direction of the part line, which can be pressed into the material of the profile ends to be connected by means of the rod elements and to their force - And form-fitting connection with the connecting element.
Die weitere Ausbildung des Erfindungsgegenstandes geht aus den Merkmalen der Unteransprüche hervor.The further development of the subject matter of the invention is evident from the features of the subclaims.
Die Erfindung läßt sich, soweit sie die Verbindung von Kunststoffrohren betrifft, aufgrund der minimalen Montagezert äußerst vorteilhaft bei der Installation von Trinkwassersystemen in Häusern anwenden, so daß erhebliche Lohnkosteneinsparungen möglich sind. Das erfindungsgemäß ausgebildete Verbindungselement, mit dem eine hochfeste Verbindung der Profiienden erzielbar ist, ist sehr kostengünstig herstellbarThe invention can, insofar as it relates to the connection of plastic pipes, be used extremely advantageously in the installation of drinking water systems in houses due to the minimal assembly concert, so that considerable labor cost savings are possible. The connecting element designed according to the invention, with which a high-strength connection of the profile ends can be achieved, can be produced very inexpensively
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung prinzipiell dargestellt und wird nachstehend beschrieben. Es zeigenAn embodiment of the invention is shown in principle in the drawing and is described below. Show it
Figur 1 eine Explosionsdarstellung einer Rohrverbindung undFigure 1 is an exploded view of a pipe joint and
Figur 2 eine Seitenansicht der Rohrverbindung, die das Montageprinzip erkennen läßt.Figure 2 is a side view of the pipe connection, which shows the principle of assembly.
Die dargesteKe Verbindung von zwei Kunststoffrohren besteht aus einem muffenartgen Verbindungselement 1 , das je drei über seine Enden in Mantellinienrichtung sich hinaus erstreckende Stangenetemente 2a,2b mit radial einwärts gerichteten Zähnen 3 aufweist, die mitteis über die Stangenelemente 2a,2b schiebbarer Anpressringe 4a,4b in das Material der zu verbindenden Profilenden 5a,5b eindrückbar sind und zu deren kraft- und formschlüssigen Verbindung mit dem Verbindungselementl führen. Die Anpressringe 4a,4b sind innen konisch ausgebildet ist und befinden sich, wie dies die Figur 2 zeigt, vor dem Herstellen der Rohrverbindung auf dem Verbindungselement 1 , von dem aus sie über die Stangenelemente 2a bzw 2b geschoben werden (gestrichelte Darstellung). Die Länge der Anpressringe 4a, 4b ist zweckmäßigerweise so gewählt, daß sie mindestens der Länge der Stangeneiemente 2a, 2b entspricht, damit letztere bei der fertig montierten Rorverbindung völlig abgedeckt sind.The DargestKe connection of two plastic pipes consists of a sleeve-type connecting element 1, each having three rod elements 2a, 2b extending beyond its ends in the direction of the generatrix with radially inwardly directed teeth 3, the middle of the rod elements 2a, 2b pushing pressure rings 4a, 4b in the material of the profile ends 5a, 5b to be connected can be pressed in and lead to their non-positive and positive connection with the connecting element. The pressure rings 4a, 4b are conical on the inside and are, as shown in FIG. 2, before the pipe connection is made on the connecting element 1, from which they are pushed over the rod elements 2a or 2b (dashed line). The length of the pressure rings 4a, 4b is expediently chosen so that it corresponds at least to the length of the rod elements 2a, 2b so that the latter are completely covered when the Ror connection is fully assembled.
Das muffenartige Verbindungelement 1 ist an beiden Enden auf den Innendurchmesser der zu verbindenden Profil- bzw. Rohrenden 5a,5b abgestuftThe sleeve-like connecting element 1 is stepped at both ends on the inside diameter of the profile or pipe ends 5a, 5b to be connected
Hier nicht dargestellt sind Dichtungen, die auf den Abstufungen 6a, 6b des Verbindungselementes 1 angeordnet sein können.Not shown here are seals which can be arranged on the steps 6a, 6b of the connecting element 1.
Die Stangenelemente 2a,2b können aus Stahlband oder Kunststoffband bestehen wobei die radial einwärts gerichteten Zähne 3 aus dem Material herausgeformt sind.The rod elements 2a, 2b can consist of steel band or plastic band, the radially inwardly directed teeth 3 being formed from the material.
Das Verbindungeiement 1 und die Stangenelemente 2a,2b können einstückig ausgebildet sein. In diesem Fall bestehen Sie aus einem Werkstoff, der härter als der der zu verbindenden Profilenden 5a,5b ist. The connecting element 1 and the rod elements 2a, 2b can be formed in one piece. In this case, they consist of a material that is harder than that of the profile ends 5a, 5b to be connected.
