Fig. 1 zeigt zwei Armaturenteile 1 und 2, die beispielsweise ein Gehäuse, ein Rohrstück, ein hydraulisches Gerät usw. sein können, wobei insbesondere vorzugsweise ein breiter Armaturenteil 1 in Form eines Gehäuseteils einer Wasserarmatur mit einer zumindest angenähert zylindrischen Aussenkontur und ein seitlicher Armaturenteil 2 in Form eines Auslaufrohres mit einem Auslauf 3 für Wasser oder eine andere Flüssigkeit dargestellt sind. Im Sinne der Erfindung bezieht sich der Begriff "hydraulisch" auf irgendeine Flüssigkeit. Das Auslaufrohr 2 weist einen axialen Hohlraum oder Durchlass 4 auf, der mit einer den Auslauf 3 bildenden Öffnung kommuniziert. Die Armaturenteile 1 und 2 weisen je eine axiale Symmetrie- oder Längsachse 5 bzw. 6 auf, die sich in ein und derselben Ebene befinden, und sind miteinander durch eine Befestigungsvorrichtung 7 in enger Berührung verbunden. 1 shows two fitting parts 1 and 2, which can be, for example, a housing, a piece of pipe, a hydraulic device, etc., in particular preferably a wide fitting part 1 in the form of a housing part of a water fitting with an at least approximately cylindrical outer contour and a side fitting part 2 are shown in the form of an outlet pipe with an outlet 3 for water or another liquid. For the purposes of the invention, the term "hydraulic" refers to any liquid. The outlet pipe 2 has an axial cavity or passage 4 which communicates with an opening forming the outlet 3 . The fitting parts 1 and 2 each have an axial symmetry or longitudinal axis 5 or 6 , which are located in one and the same plane, and are connected to one another by a fastening device 7 in close contact.

Der Armaturenteil 1 weist eine Zylinderwand 8 auf, die mit einer durchgehenden Öffnung 9 für eine Verbindung mit dem Armaturenteil 2 versehen ist.The valve part 1 has a cylinder wall 8 which is provided with a through opening 9 for connection to the valve part 2 .

Die Zylinderwand 8, deren Form im Wesentlichen sonst durch die Verbindung mit dem Armaturenteil 2 nicht beeinträchtigt wird, berührt somit eine Schnittfläche des Armaturenteils 2, die zu diesem Zweck in der besonderen Form einer sogenannten Durchdringung ausgebildet ist, so dass die Form des einen Endes 10 des Armaturenteils 2 an die Aussenfläche der Zylinderwand 8 des Armaturenteils 1 nach Massgabe eines durch die Achsen 5 und 6 gebildeten Winkels W angepasst ist. Dadurch kann der rohrförmige Armaturenteil 2, der den kleineren Durchmesser aufweist, stumpf unter dem vorgegebenen Winkel W an den Armaturenteil 1 gefügt werden.The cylinder wall 8, the shape of which is essentially not impaired by the connection to the valve part 2 , thus touches a cut surface of the valve part 2, which is designed for this purpose in the special shape of a so-called penetration, so that the shape of one end 10 of the fitting part 2 is adapted to the outer surface of the cylinder wall 8 of the fitting part 1 in accordance with an angle W formed by the axes 5 and 6 . As a result, the tubular fitting part 2, which has the smaller diameter, can be butt joined to the fitting part 1 at the predetermined angle W.

Die Befestigungsvorrichtung 7 nach Fig. 1 und 2 umfasst zwei Teile, nämlich einen Befestigungsteil 11 und ein Gewinderohr 12, die beide relativ dünnwandig sind. Der Befestigungsteil 11 kann vorzugsweise, wie in den Figuren 3 bis 6 dargestellt, rohrförmig mit zwei Öffnungen 13 und 14 ausgebildet sein. Die Öffnung 14 befindet sich in einer einen Flansch 15 aufweisenden vorderen Zone 16. Der Flansch 15 ist derart zylindrisch und/oder gewölbt ausgebildet, dass seine Rückseite sich an die zylindrische innere Seite der Wand 8 des Armaturenteils 1 anschmiegt. Ein Bereich an dem anderen Ende des Befestigungsteils 11 weist ein Innengewinde 17 zwischen einer ringförmigen Stirnfläche 18 und einer Schulter 19 auf.The fastening device 7 according to FIGS. 1 and 2 comprises two parts, namely a fastening part 11 and a threaded tube 12, both of which are relatively thin-walled. The fastening part 11 can, as shown in FIGS. 3 to 6 , preferably be tubular with two openings 13 and 14 . The opening 14 is located in a front zone 16 having a flange 15. The flange 15 is cylindrical and / or arched in such a way that its rear side conforms to the cylindrical inner side of the wall 8 of the fitting part 1 . A region at the other end of the fastening part 11 has an internal thread 17 between an annular end face 18 and a shoulder 19 .

Das Gewinderohr 2 nach Fig. 2 weist eine Partie 20 mit einem Durchmesser D1 und eine Partie 21 mit einem Durchmesser D2 auf, die je mit einem Aussengewinde 22 bzw. 23 versehen sind, wobei D2 etwas grösser als D1 ist. Zwischen den Partien 20 und 21 befindet sich eine Zwischenpartie 24 ohne Gewinde, durch die sie fest verbunden sind. Das Aussengewinde 22 der Partie 20 hat eine kleinere Steigung als das Aussengewinde 23 der Partie 21. Wie aus Fig. 2 ersichtlich, weist der Armaturenteil 2 ein Innengewinde 25 mit einer Steigung auf, die derjenigen des Aussengewindes 23 entspricht. Das Innengewinde 25 erstreckt sich von einer inneren Schulter 26 des Armaturenteils 2 aus gegen die Zone 16 desselben hin, jedoch in einer Höhe, die nicht grösser als etwa die doppelte Höhe der Partie 21 ist.The threaded pipe 2 of Fig. 2 has a portion 20 having a diameter D1 and a portion 21 having a diameter D2, which are each provided with an external thread 23 or 22, wherein a bit D2 is greater than D1. Between the parts 20 and 21 there is an intermediate part 24 without thread, through which they are firmly connected. The external thread 22 of the section 20 has a smaller pitch than the external thread 23 of the section 21. As can be seen from FIG. 2 , the fitting part 2 has an internal thread 25 with a pitch which corresponds to that of the external thread 23 . The internal thread 25 extends from an inner shoulder 26 of the fitting part 2 towards the zone 16 thereof, but at a height which is not greater than approximately twice the height of the section 21 .

Die Befestigungsvorrichtung nach den Figuren 1 bis 6 funktioniert folgendermassen:
Der vorzugsweise - beispielsweise aus Kunststoff - gepresste Befestigungsteil 11, der auch Formstück genannt wird, wird von innen her in die Öffnung 9 des Armaturen- oder Gehäuseteils 1 eingesetzt. Auf Grund seiner Formgebung liegt dann das Formstück 11 drehfest am Gehäuseteil an. Das Gewinderohr 12 wird über sein Aussengewinde 22 mit der kleineren Steigung bis zum Anschlag in das Befestigungsteil 11 eingeschraubt. Anschliessend wird der Armaturenteil 2, der auch Auslaufrohr genannt wird, über die Partie 21 des Gewinderohrs 12 derart gefügt, dass sein Ende 10 bezüglich des Winkels W in der richtigen Position am Gehäuseteil 1 anliegt. Mittels einer flexiblen Welle wird nun vom Gehäuseteil 1 her das Gewinderohr 12 gedreht, so dass sein mit der grösseren Steigung versehenes Gewinde 23 in Eingriff mit dem Innengewinde 25 des Auslaufrohrs 2 gelangt. Durch ein festes Drehen des Gewinderohrs 12 wird das Auslaufrohr 2 mit grosser Kraft gegen den Gehäuseteil 1 gedrückt. Infolge der Steigungsdifferenz sind sehr grosse Kräfte erzielbar. Als Variante kann auch das Gewinde mit der grossen Steigung formstückseitig und jenes mit geringerer Steigung auslaufrohrseitig angeordnet sein.
The fastening device according to Figures 1 to 6 works as follows:
The fastening part 11, which is preferably pressed, for example from plastic, and which is also called a molded part, is inserted from the inside into the opening 9 of the fitting or housing part 1 . Because of its shape, the shaped piece 11 then lies against the housing part in a rotationally fixed manner. The threaded pipe 12 is screwed into the fastening part 11 up to the stop via its external thread 22 with the smaller pitch. The fitting part 2, which is also called the outlet pipe, is then joined over the part 21 of the threaded pipe 12 in such a way that its end 10 lies in the correct position on the housing part 1 with respect to the angle W. The threaded tube 12 is now rotated from the housing part 1 by means of a flexible shaft, so that its thread 23 provided with the larger pitch comes into engagement with the internal thread 25 of the outlet tube 2 . By turning the threaded tube 12 firmly, the outlet pipe 2 is pressed against the housing part 1 with great force. As a result of the gradient difference, very large forces can be achieved. As a variant, the thread with the large pitch can also be arranged on the fitting side and that with a smaller pitch on the outlet pipe side.

Eine mögliche Ausführung des Flansches 15 des Befestigungsteils 11 im Bereich der Öffnung 9 des Armaturenteils 1 ist in den Figuren 7 und 8 vergrössert dargestellt, in denen auch die kanalartige Kommunikation 27 zwischen den zwei Armaturenteilen 1 und 2 angedeutet ist. A possible embodiment of the flange 15 of the fastening part 11 in the area of the opening 9 of the fitting part 1 is shown enlarged in FIGS. 7 and 8 , in which the channel-like communication 27 between the two fitting parts 1 and 2 is also indicated.

Die Ausführung nach Fig. 9 und 10 umfasst einen Befestigungsteil 11 gleicher oder ähnlicher Art wie bei der Ausführung nach Fig. 2. Das Gewinderohr 28 weist jedoch nach dieser Ausführung eine untere Partie 29 mit einem Aussengewinde 30 und eine glatte obere Partie 31 auf, die mit einem ringförmigen vorstehenden Flansch 32 endet. Der Armaturenteil ist in diesem Fall in Form eines Auslaufrohrstücks 33 ausgebildet und weist einen axialen Hohlraum oder Durchlass 4 mit einer Mündung 34 auf. Die Armaturenteile 1 und 33 weisen in diesem Fall ebenfalls je eine axiale Längsachse 5 bzw. 6 auf, die sich in ein und derselben Ebene befinden, und sind miteinander durch die Befestigungsvorrichtung 7 in enger Berührung verbunden. Das Auslaufrohrstück 33 wird durch die Wirkung des - mit dem Innengewinde am Befestigungsteil 11 zusammenwirkenden - Aussengewindes 30 des Gewinderohrs 28 und seiner Schulter 32 eingeklemmt gehalten, die gegen einen ringförmigen Absatz 35 des Auslaufrohrstücks 33 als Gegenschulter drückt.The embodiment according to FIGS. 9 and 10 comprises a fastening part 11 of the same or similar type as in the embodiment according to FIG. 2. However, according to this embodiment, the threaded tube 28 has a lower part 29 with an external thread 30 and a smooth upper part 31 which ends with an annular protruding flange 32 . In this case, the fitting part is designed in the form of an outlet pipe piece 33 and has an axial cavity or passage 4 with an opening 34 . The fitting parts 1 and 33 in this case also each have an axial longitudinal axis 5 or 6 , which are located in one and the same plane, and are connected to one another by the fastening device 7 in close contact. The outlet pipe section 33 is clamped in by the action of the external thread 30 of the threaded pipe 28 and its shoulder 32 , which cooperates with the internal thread on the fastening part 11 and which presses against an annular shoulder 35 of the outlet pipe section 33 as a counter shoulder.

Die Befestigungsvorrichtung nach Fig. 9 und 10 funktioniert folgendermassen:
Der vorzugsweise gepresste Befestigungsteil 11, der auch Formstück genannt wird, wird von innen her in die Öffnung 9 des Armaturen- oder Gehäuseteils 1 eingesetzt. Auf Grund seiner Formgebung liegt dann das Formstück 11 unter Berücksichtigung des Winkels W drehfest am Gehäuseteil 1 an. Das Gewinderohr 28 wird durch die Öffnung 34 des Auslaufrohrstücks 33 bis zum Anschlag beim Absatz 35 eingeführt. Danach wird das Auslaufrohrstück 33 derart über den Befestigungsteil 11 gefügt, dass dieser in der richtigen Drehlage bezüglich des Winkels W am Gehäuseteil 1 anliegt. Vom Gehäuseteil 1 her oder vorzugsweise von der dem Gehäuseteil 1 abgewandten Seite her wird nun mittels einer gegebenenfalls flexiblen Welle das Gewinderohr 28 gedreht, bis das Auslaufrohrstück 33 gegen den Gehäuseteil 1 drückt. Das Gewinderohr 28 gelangt somit einerseits mit dem Innengewinde 17 des Befestigungsteils 11 in Eingriff und drückt andererseits mit der Schulter 32 gegen den Absatz 35 des Auslaufrohrstücks 33. Die Abmessungen sind so gewählt, dass in dieser Position der Endbereich des Armaturenteils 33 die Mantelfläche 8 des Armaturenteils 1 berührt. In das Auslaufrohrstück 33 kann nachträglich ein weiteres Rohrelement 36 eingesetzt und mittels eines Schnappverschlusses 37 befestigt werden.
The fastening device according to FIGS. 9 and 10 works as follows:
The preferably pressed fastening part 11 , which is also called a fitting, is inserted from the inside into the opening 9 of the fitting or housing part 1 . Because of its shape, the molded part 11 then bears against the housing part 1 in a rotationally fixed manner, taking into account the angle W. The threaded pipe 28 is inserted through the opening 34 of the outlet pipe piece 33 until it stops at the shoulder 35 . Then the outlet pipe piece 33 is fitted over the fastening part 11 in such a way that it lies in the correct rotational position with respect to the angle W on the housing part 1 . From the housing part 1 or preferably from the side facing away from the housing part 1, the threaded tube 28 is now rotated by means of a possibly flexible shaft until the outlet pipe piece 33 presses against the housing part 1 . The threaded tube 28 thus engages on the one hand with the internal thread 17 of the fastening part 11 and on the other hand presses with the shoulder 32 against the shoulder 35 of the outlet pipe piece 33. The dimensions are chosen so that in this position the end region of the fitting part 33 the outer surface 8 of the fitting part 1 touches. A further tubular element 36 can subsequently be inserted into the outlet tube piece 33 and fastened by means of a snap lock 37 .

Die Befestigungsvorrichtung 11, 12 oder 11, 28 ist in den beschriebenen Beispielen vorgesehen zum Einbau in einem seitlichen Armaturenteil 2, 33, der in einem Endbereich einen Hohlraum 4 aufweist, in dem vorzugsweise peripher ein inneres Befestigungsmittel 25 bzw. 35 für die Befestigungsvorrichtung 7 vorhanden ist. Es könnten jedoch auch andere Befestigungsmittel verwendet werden.The fastening device 11, 12 or 11, 28 is provided in the examples described for installation in a lateral fitting part 2, 33 which has a cavity 4 in an end region, in which an inner fastening means 25 or 35 for the fastening device 7 is preferably provided peripherally is. However, other fasteners could be used.

Durch die erfindungsgemässe Befestigungsvorrichtung wird die Verbindung zwischen den Armaturenteilen 1 und 2 bzw. 1 und 33 nicht ohne weiteres lösbar, so dass dadurch eine vollkommene Einheit als Ersatz für ein entsprechendes einstückiges Gebilde entsteht. Die zwei unlösbar verbundenen Teile erweisen sich als besonders vorteilhaft im Hinblick auf ihre Oberflächenbehandlung. Denn ein entsprechendes einstückiges Gebilde wäre, insbesondere im Bereich der scharfkantigen Berührungslinie der beiden Armaturenteile, relativ schwer zu reinigen, schleifen, polieren, verchromen, lackieren usw. Da nach der Erfindung die Armaturenteilen 1, 2 bzw. das Auslaufrohr 33 ursprünglich getrennt sind, können solche Oberflächenbehandlungen einwandfrei realisiert werden.The connection between the armature parts 1 and 2 or 1 and 33 is not easily detachable by the fastening device according to the invention, so that a perfect unit is created as a replacement for a corresponding one-piece structure. The two inseparably connected parts prove to be particularly advantageous with regard to their surface treatment. Because a corresponding one-piece structure would be relatively difficult to clean, grind, polish, chrome, paint, etc., especially in the area of the sharp-edged line of contact of the two fitting parts. According to the invention, the fitting parts 1, 2 and the outlet pipe 33 are originally separated, can such surface treatments can be realized flawlessly.

Für die vorliegende Erfindung ist es unbedeutend, ob die Querschnitte der Armaturen 1 und 2 kreisförmig sind oder eine andere, beispielsweise elliptische Form aufweisen. Die Zylinderwand 8 ist daher im allgemeinen als Aussenwand des Armaturenteils 1 zu verstehen. For the present invention, it is irrelevant whether the cross sections of the fittings 1 and 2 are circular or have a different, for example elliptical, shape. The cylinder wall 8 is therefore generally to be understood as the outer wall of the fitting part 1 .

Bei all diesen Varianten kann der Durchlass bzw. die Öffnung durch alle Elemente so gross sein, dass nicht nur durch die Hohlräume des Gehäuseteils 1 und des Auslaufrohrs 2 oder 33 hindurch sondern auch durch die Befestigungsvorrichtung 7 ein flexibles oder mehr oder weniger steifes als Wasserleitung dienendes Röhrchen geführt werden kann. Insbesondere kann ein flexibler Schlauch einer Ausziehbrause hindurchgeführt sein.In all these variants, the passage or the opening through all elements can be so large that not only through the cavities of the housing part 1 and the outlet pipe 2 or 33 but also through the fastening device 7 a flexible or more or less rigid serving as water pipe Tubes can be guided. In particular, a flexible hose of a pull-out spray can be passed through.
