Abstract

A safety plug for discharge pipes, mainly for sanitary installations of new buildings or in refurbishments, consists of a rotationally symmetrical spigot (1), having a plurality of diametral steps (1a, 1b, 1c), which is designed as a hollow body which is closed on the end side (2) of the smallest diametral step (1c) and which preferably has the same wall thickness (s) in the region of each of the steps (1a, 1b, 1c), the mutual transitions (ü) between the steps (1a, 1b, 1c) extending chamfered, inclined or rounded. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Schutzstopfen für Abflußrohre, vornehmlich bei der Sanitärinstallation von Neubauten bzw. bei Altbausanierungen.The invention relates to a protective plug for drain pipes, primarily in the sanitary installation of new buildings or in old building renovations.

Bislang war es im allgemeinen üblich, nach Verlegen der Abflußrohre für den Anschluß eines Spültisches oder Waschbeckens die betreffende, zuvor bereits in der Wand verlegte Rohrleitung bzw. deren Öffnung mit Knüllpapier o. dgl. auszustopfen, damit beim späteren Verputzen oder Verfliesen der Wand keine Mörtelverschmutzungen o.ä. Dinge in die Abflußrohre gelangten.So far, it has been customary, after laying the drain pipes for the connection of a sink or washbasin, to stuff the relevant pipe, which has already been laid in the wall, or its opening, with crumpled paper or the like, so that when later plastering or tiling of the wall, no mortar contamination or similar Things got into the drain pipes.

Der Nachteil dieser bisherigen Methode liegt aber vor allem darin, daß zumeist über diesen Knüllpapier­stopfen hinweg gegipst oder geplättelt wurde, was zur Folge hatte, daß der Installateur dann stets durch Abklopfen der Wand recht mühsam die Abflußrohr­öffnung suchen und wieder freischlagen mußte, wenn er das Waschbecken o. dgl. anschließen wollte.The disadvantage of this previous method, however, lies primarily in the fact that plaster was usually plastered or flattened over this plug of paper, with the result that the installer then always had to find the drain pipe opening with great difficulty by knocking on the wall and had to knock it open again when he washed the sink wanted to connect.

Die Aufgabe der vorliegenden Erfindung besteht deshalb auch darin, einen leicht wieder entfernbaren Schutz­stopfen für derartige Abflußrohröffnungen vorzuschlagen, der in einfacher Weise letztere vor dem Eindringen von Verschmutzungen schützt und den Rohrendbereich für den späteren Syphonanschluß freihält.The object of the present invention is therefore also to propose an easily removable protective plug for such drain pipe openings, which protects the latter from the ingress of dirt in a simple manner and keeps the pipe end area free for the subsequent siphon connection.

Gelöst wird diese Aufgabe dabei durch die in den Patentansprüchen angegebenen, baulichen Merkmale. Die Zeichnung stellt ein Ausführungsbeispiel der Neuerung dar, das im folgenden anhand dieser Skizzen noch näher beschrieben wird.This problem is solved by the structural features specified in the claims. The drawing shows an embodiment of the innovation, which is described in more detail below with reference to these sketches.

Es zeigen im einzelnen:

  • Fig. 1 eine Seitenansicht des neuen Schutzstopfens im Längsschnitt sowie im Einsatzzustand und
  • Fig. 2 eine Seitenansicht zu Fig. 1 aus Pfeilrichtung F.
The individual shows:
  • Fig. 1 is a side view of the new protective plug in longitudinal section and in use and
  • 2 shows a side view of FIG. 1 from the direction of arrow F.

Der in Fig. 1 dargestellte Schutzstopfen besteht in seinem Grundaufbau aus einem rotationssymmetrischen, mehrere Durchmeserabstufungen 1a, 1b, 1c aufweisenden Zapfen und ist somit für in einer Wand "W" verlegte Abflußrohre "R" unterschiedlichen Durchmessers ein­setzbar. In spezieller baulicher Ausgestaltung ist dabei vorgesehen, daß der neuerungsgemäße Stopfen als Hohlkörper mit vorzugsweise gleicher Wandstärke "s" im Bereich jeder der Abstufungen 1a, 1b, 1c ausge­bildet ist, wobei die gegenseitigen Übergänge "ü" letzterer 1a, 1b, 1c gefast, geneigt oder ausgerundet verlaufen und sich somit gut in die Rohrenddichtung "D" einfügen. Um in dieser Einbaulage nun auch Spül­vorgänge für die Rohrleitungen "R" durchführen zu können, ist erfindungsgemäß weiterhin vorgesehen, daß die an sich geschlossen ausgebildete Stirnseite 2 der kleinsten Durchmesserstufe 1c ggf. zusätzlich noch mit sternförmig oder ähnlich verlaufenden Ein­kerbungen 3 versehen ist, wobei die Wandstärke "s₁" der Stirnseite 2 wesentlich kleiner als diejenigen "s" der Abstufungen 1a, 1b, 1c gehalten wird, so daß die gekerbte Stirnseite 2 und 3 leicht durchstoßen werden kann, z.B. zum Einführen eines Spülschlauches. Als Material für den Schutzstopfen eignet sich am besten irgendein Kunststoffmaterial ausreichender Festigkeit.The protective plug shown in FIG. 1 consists in its basic structure of a rotationally symmetrical spigot having several diameter gradations 1a, 1b, 1c and can thus be used for drain pipes "R" of different diameters laid in a wall "W". In a special structural design, it is provided that the plug according to the innovation is designed as a hollow body with preferably the same wall thickness "s" in the area of each of the gradations 1a, 1b, 1c, the mutual transitions "ü" of the latter 1a, 1b, 1c chamfered, inclined or rounded and fit well into the pipe end seal "D". In order to be able to carry out flushing operations for the pipelines “R” in this installed position, it is further provided according to the invention that the end face, which is designed to be closed 2 of the smallest diameter step 1c is optionally additionally provided with star-shaped or similarly extending notches 3, the wall thickness "s₁" of the end face 2 being kept substantially smaller than those "s" of the gradations 1a, 1b, 1c, so that the notched end face 2 and 3 can be easily pierced, e.g. for inserting a flushing hose. Any plastic material of sufficient strength is best suited as the material for the protective plug.
