Abstract

The joint sleeve is for connection of hard or soft pipes of pref. thermoplastic material, to smooth unprofiled pipe ends. The sleeve consists of two pipe insertion sections, and an intermediate collar, serving as a stop for the pushed-in pipe ends. The internal surfaces of the insertion sections (1, 2) have longitudinal ribs (4). The ribs extend from the ends (6, 7) of the sections over parts of their internal surfaces, and decrease in size inwards. The sleeve consists of a transparent synthetic resin.

Description

  

  
 



   Die Erfindung betrifft eine Muffe zur Verbindung aus   we    chem oder hartem, vorzugsweise thermoplastischem Material hergestellten Rohren mit glatten, unprofilierten Rohrenden, welche Muffe aus mindestens zwei Rohreinschubteilen und aus einem zwischen diesen Teilen angeordneten, als Anschlag   für    die Rohrenden dienenden, inneren Bund besteht.



   Zur Verlegung von Kunststoffrohren in Neubauten werden oft Verbindungsmuffen ohne Halterippen   für    die zu verbindenden Rohrenden verwendet. Diese Muffen haben den Nachteil, dass in die   Einschuböffnungen    gesteckte   Kunststoff-    rohre leicht herausfallen, was bei der anschliessenden Betonierung in Neubauten   verhängnisvolle    Auswirkungen haben kann.



   Es ist auch bekannt, die Einschubbohrungen bei Muffen mit mehr oder weniger vielen Ringrippen zu versehen, welche das Herausfallen der Kunststoffrohre verhindern. Die Herstellung solcher Muffen ist   verhältnismässig    kostspielig.



     Insbesondere      fflr    die Verlegung elektrischer Leitungen   genfi-    gen auch einfachere Muffen.



   Die Erfindung stellt sich zur Aufgabe, eine   verhaitnismas-    sig einfache, nicht zu kostspielige Muffe zu schaffen, bei welcher ein leichtes Herausfallen der zu verbindenden Rohrenden aus den Rohreinschubteilen verhindert wird.



     Erfindungsgemass    wird dies dadurch erreicht, dass die Innenseiten der Rohreinschubteile mit   Langsrippen    versehen sind.



   In der Zeichnung ist ein   Ausfuhrungsbeispiel    der erfin   dungsgemassen    Muffe dargestellt. Es zeigen:
Fig. 1 einen   Langsschnitt    und
Fig. 2 einen Querschnitt durch die Muffe.



   Die aus einem Stuck   hergestellte    Muffe weist zwei Rohreinschubteile 1, 2 und einen zwischen diesen Teilen 1 und 2 angeordneten inneren Bund 3 auf, der als Anschlag fur die beiden strichliert dargestellten Kunststoffrohre 5 dient.



  dient. Rohreinschubteile 1 und 2 sind je nach   Grösse    des   Durchmessers    der Muffe mit mehreren, vorzugsweise drei bsi 5   Längsrippen    4 versehen. Die sich nach innen   verjiingen    den   Langsrippen    4 erstrecken sich von den Stirnseiten 6, 7 an   tiber    die halbe Lunge der Rohreinschubteile 1, 2. Dies hat den Vorteil, dass sich das hineingeschobene Rohrende 5 wieder etwas ausdehnen kann, wodurch ein besserer Sitz des Rohres 5   gewahrleistet    wird.



   Die vorliegende Erfindung ist nicht auf das   dargestellte      Ausfuhrungsbeispiel      beschränkt.   



   Die miteinander zu vereinigenden Rohrenden   können,    wie im   Ausfuhrungsbeispiel      dargestellt,    gleichen   Aussendurch    messer haben oder aber auch verschiedene Aussendurchmesser aufweisen, wobei im letzteren Falle, die diese Rohrenden aufzunehmen bestimmten Einschubteile der Muffe, entsprechende Innendurchmesser aufweisen.



   Die Achsen der zur Aufnahme je eines Rohrendes bestimmten Einschubteile   können,    wie im   Ausfuhrungsbeispiel      dargestellt,    einer gemeinsamen Geraden   angehören    oder einen Winkel miteinander einschliessen.



   Beide   Muffenhaiften      können      sowohl    mit je einem Rohr   einschubteil    1, 2 als auch mit mehreren Rohreinschubteilen zur gegenseitigen Verbindung von mehr als zwei Rohrenden 5 versehen sein.



   Die Muffe wird vorzugsweise aus einem transparenten   Polyathylenharz    hergestellt. Durch die Verwendung eines transparenten Kunstharzes ist auch eine visuelle Kontrolle   tiber    den richtigen Einschub der Rohrenden   möglich.    



  
 



   The invention relates to a sleeve for connecting pipes made of we chem or hard, preferably thermoplastic material with smooth, unprofiled pipe ends, which sleeve consists of at least two pipe insert parts and an inner collar arranged between these parts and serving as a stop for the pipe ends.



   When laying plastic pipes in new buildings, connecting sleeves without retaining ribs are often used for the pipe ends to be connected. These sleeves have the disadvantage that plastic pipes inserted into the insertion openings easily fall out, which can have disastrous effects when concreting in new buildings.



   It is also known to provide the insertion bores in sleeves with a greater or lesser number of annular ribs which prevent the plastic pipes from falling out. The manufacture of such sleeves is relatively expensive.



     Simpler sleeves are also necessary, particularly for laying electrical lines.



   The object of the invention is to create a relatively simple, not too expensive sleeve in which the pipe ends to be connected are prevented from easily falling out of the pipe insertion parts.



     According to the invention, this is achieved in that the insides of the tube insert parts are provided with longitudinal ribs.



   In the drawing, an exemplary embodiment of the socket according to the invention is shown. Show it:
Fig. 1 is a longitudinal section and
Fig. 2 shows a cross section through the sleeve.



   The sleeve made from one piece has two pipe insert parts 1, 2 and an inner collar 3, which is arranged between these parts 1 and 2 and which serves as a stop for the two plastic pipes 5 shown in broken lines.



  serves. Pipe insert parts 1 and 2 are provided with several, preferably three up to 5 longitudinal ribs 4, depending on the size of the diameter of the sleeve. The inward tapering of the longitudinal ribs 4 extend from the end faces 6, 7 over half the lungs of the tube insert parts 1, 2. This has the advantage that the tube end 5 pushed in can expand again somewhat, whereby a better fit of the tube 5 is guaranteed.



   The present invention is not limited to the exemplary embodiment shown.



   The pipe ends to be joined together can, as shown in the exemplary embodiment, have the same outside diameter or also have different outside diameters, in the latter case the specific insertion parts of the sleeve having corresponding inside diameters to accommodate these pipe ends.



   As shown in the exemplary embodiment, the axes of the slide-in parts intended for receiving one pipe end each can belong to a common straight line or form an angle with one another.



   Both socket halves can be provided both with one pipe insert part 1, 2 each and with several pipe insert parts for the mutual connection of more than two pipe ends 5.



   The sleeve is preferably made of a transparent polyethylene resin. The use of a transparent synthetic resin also enables visual control of the correct insertion of the pipe ends.
