BeschreibungDescription Fixierunas- und Markierunashilfe für PreßfittinaeFixing and marking aid for press fittings

Wenn Sanitärinstallateure zu den neuen Montagesystemen mit den sog. Preßfittingen befragt werden, gibt es in der Regel folgende Antwort: &ldquor;Nach anfänglichen Schwierigkeiten gibt es kaum noch Probleme, bis auf die axiale Beweglichkeit des Kupferrohres im Fitting." Der Anpreßdruck des O-Ringes, der vom Innendurchmesser des O-Ringes bestimmt wird, ist nicht ausreichend, um das Rohr im Fitting zu fixieren.When plumbers are asked about the new assembly systems with so-called press fittings, the answer is usually: "After initial difficulties, there are hardly any problems anymore, except for the axial mobility of the copper pipe in the fitting." The contact pressure of the O-ring, which is determined by the inner diameter of the O-ring, is not sufficient to fix the pipe in the fitting.

Die Verkleinerung des O-Ring-Innendurchmessers ist problematisch, weil vermutlich der O-Ring durch das Rohr aus seinem Sitz herausgedrückt würde.Reducing the O-ring inner diameter is problematic because the O-ring would probably be pushed out of its seat by the pipe.

Die nachstehend beschriebene Verbesserung scheint eine machbare Problemlösung zu bieten.The improvement described below appears to provide a feasible solution to the problem.

Figur 1 zeigt den Preßfitting (1) mit O-Ring (2), der im Bereich der Außenkante eine kegelförmige Einstanzung (3) aufweist, deren Spitze (4) nur so weit in die Muffe (8) des Fittings (1) hineinragt, daß das Kupferrohr einen festen Halt bekommt, und das Einschieben des Kupferrohres nur mit etwas mehr Kraftaufwand erfolgt.Figure 1 shows the press fitting (1) with O-ring (2), which has a conical punched hole (3) in the area of the outer edge, the tip (4) of which only extends far enough into the socket (8) of the fitting (1) to hold the copper pipe firmly and to push the copper pipe in only with a little more force.

Die Spitze (4) kann auch als Markierungshilfe herangezogen werden, indem das Kupferrohr einmal um die eigene Achse gedreht wird. Die dadurch verursachte Schleifspur kann als Erkennungshilfe für eine eventuelle axiale Verschiebung des Kupferrohres genutzt werden. Der Installateur erkennt sofort, daß er den Fitting nochmals ausrichten muß, bevor er ihn anpreßt.The tip (4) can also be used as a marking aid by rotating the copper pipe once around its own axis. The grinding mark caused by this can be used to detect any axial displacement of the copper pipe. The installer immediately recognizes that he must realign the fitting again before pressing it on.

Figur 2 zeigt den Preßfitting (1) mit einer weiteren Möglichkeit der Fixierung und Markierung, nämlich mit einer kleinen Abkantung (5) am Muffenumfang, deren Unterkante ebenfalls einen Effekt wie die Spitze (4) Fig. 1 bewirkt.Figure 2 shows the press fitting (1) with another possibility of fixing and marking, namely with a small bevel (5) on the socket circumference, the lower edge of which also produces an effect like the tip (4) in Fig. 1.

Figur 3 zeigt den Preßfitting (1) mit einer kegelförmigen Einstanzung (6) in die Stirnkante der Muffe (8), deren unterer Radius auch einen Fixierungs- und Markierungseffekt erzeugt.Figure 3 shows the press fitting (1) with a conical punch (6) in the front edge of the socket (8), the lower radius of which also creates a fixing and marking effect.
