Beschreibung Fixierunashilfe für PreßfittinaeDescription Fixing aid for press fittings

Wenn Sanitärinstallateure zu den neuen Montagesystemen mit den sog. Preßfittingen befragt werden, gibt es in der Regel folgende Antwort: „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 ORing-lnnendurchmessers ist problematisch, weil vermutlich der O-Ring durch das Rohr aus seinem Sitz herausgedrückt würde.Reducing the inner diameter of the O-ring 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.

Die ZeichnungThe drawing

zeigt den Preßfitting (1) mit O-Ring (2), der zwischen dem Anschlag (5), für das Rohr (6), und dem O-Ring (2), eine kegelförmige Einstanzung (3) aufweist, deren Spitze nur so weit in die Muffe (4) des Preßfittings (1) hineinragt, daß das Kupferrohr (6) einen festen Halt bekommt, und das Einschieben des Kupferrohre (6) nur mit etwas mehr Kraftaufwand erfolgt.shows the press fitting (1) with O-ring (2), which has a conical punched hole (3) between the stop (5) for the pipe (6) and the O-ring (2), the tip of which only extends far enough into the socket (4) of the press fitting (1) to hold the copper pipe (6) firmly and to push in the copper pipe (6) only with a little more force.

Claims (3)

1. Fixierungshilfe für Preßfittinge dadurch gekennzeichnet, daß ein Preßfitting (1) zwischen dem Anschlag (5) des Kupferrohres (6), und dem O-Ring (2) eine kegelförmige, bzw. kugelförmige Einstanzung (3) aufweist, deren Spitze um einen bestimmten Betrag in die Muffe (4) hineinragt. 1. Fixing aid for press fittings, characterized in that a press fitting ( 1 ) has a conical or spherical punched portion ( 3 ) between the stop ( 5 ) of the copper pipe ( 6 ) and the O-ring ( 2 ), the tip of which projects into the sleeve ( 4 ) by a certain amount. 2. Fixierungshilfe für Preßfittinge nach Anspruch 1 dadurch gekennzeichnet, daß auch andere Fixierungshilfen, wie z. B. Einkerbungen in die Muffe (4), geschützt sein sollen. 2. Fixing aid for press fittings according to claim 1, characterized in that other fixing aids, such as notches in the sleeve ( 4 ), should also be protected. 3. Fixierungshilfe für Preßfittinge nach Anspruch 1 und 2 dadurch gekennzeichnet, daß auch eine oder mehrere Einstanzungen, oder Einkerbungen auf beiden Muffenseiten des Preßfittings (1) geschützt sein sollen. 3. Fixing aid for press fittings according to claim 1 and 2, characterized in that one or more punched holes or notches on both socket sides of the press fitting ( 1 ) are also to be protected.
