Description

Die Erfindung betrifft einen S-Anschluss zum Anschließen einer Armatur an eine Wasserleitung. Bekannte S-Anschlüsse zu diesem Zweck haben ein 1/2"-Außengewinde zur Verbindung mit einer Wasserleitung und ein 3/4"-Außengewinde zur Verbindung mit einer Armatur, wobei die Längsachsen der genannten Gewinde parallel und in einem Abstand voneinander angeordnet sind.The invention relates to an S-connection for connecting a valve to a water pipe. Known S-ports for this purpose have a 1/2 "male thread for connection to a water conduit and a 3/4" male thread for connection to a fitting, the longitudinal axes of said threads being parallel and spaced apart.

Die S-Anschlüsse sind insgesamt S-förmig, so dass durch Anpassen des Drehwinkels nach dem Einschrauben des 1/2"-Außengewindes in ein Innengewinde eines Wasserleitungsanschlusses eine seitliche Position (also die Anordnung der Längsachse des 3/4"-Außengewindes in der Ebene der Wand) des mit der Armatur zu verbindenden 3/4"-Außengewindes justiert werden kann. Der Abstand zwischen den beiden Längsachsen wird wegen dieser Einstellmöglichkeit auch als Verstellbarkeit bezeichnet. Ein genaues Justieren der seitlichen Position des 3/4"-Außengewindes ist insbesondere wichtig, um eine Armatur mit zwei in einem genormten Abstand voneinander angeordneten Anschlüssen für Warm- und Kaltwasser exakt waagerecht montieren zu können.The S-terminals are S-shaped as a whole, so that by adjusting the angle of rotation after screwing the 1/2 "male thread into an internal thread of a water pipe connection a lateral position (ie the arrangement of the longitudinal axis of the 3/4" male thread in the plane The distance between the two longitudinal axes is also referred to as adjustability because of this adjustment possibility, and it is particularly important to precisely adjust the lateral position of the 3/4 "external thread in order to be able to install a fitting exactly horizontally with two connections arranged at a standardized distance for hot and cold water.

Zusätzlich zu dieser seitlichen Justierbarkeit durch Verdrehen des S-Anschlusses ist für eine einwandfreie Montage der Armatur eine Anordnung des 3/4"-Außengewindes im richtigen Abstand von der Wand erforderlich. Zumeist ist hierzu ein Abstand zwischen einer Wandscheibe und dem 1/2"-Außengewinde des S-Anschlusses zu überbrücken. Die Wandscheibe ist ein abgewinkeltes Endstück der Wasserleitung, das Befestigungslaschen aufweist, mit denen es innerhalb der Wand befestigt ist.In addition to this lateral adjustability by twisting the S-connection, an assembly of the 3/4 "male thread at the correct distance from the wall is required for a perfect assembly of the fitting. External thread of the S-connection to bridge. The wall plate is an angled end piece of the water pipe, which has fastening tabs with which it is fastened within the wall.

Um den genannten Abstand zu überbrücken, werden sogenannte Hahnverlängerungen eingesetzt, die mit einem 1/2"-Außengewinde in die Wandscheibe eingeschraubt werden und an ihrem anderen Ende ein 1/2"-Innengewinde aufweisen, in das das 1/2"-Außengewinde des S-Anschlusses eingeschraubt wird. Je nach Größe des zu überbrückenden Abstands können zwischen Wandscheibe und S-Anschluss auch mehrere Hahnverlängerungen eingesetzt werden. Die Hahnverlängerungen sind in vielen unterschiedlichen Längen in 5 mm-Abstufungen erhältlich, z. B. von 10 mm bis 50 mm Länge.To bridge the mentioned distance, so-called Hahn extensions are used, which are screwed with a 1/2 "male thread in the wall plate and at its other end a 1/2" female thread into which the 1/2 "male thread of S-connection is screwed in. Depending on the size of the distance to be bridged, between the wall plate and the S-connection also several tap extensions can be used. The tap extensions are available in many different lengths in 5 mm increments, eg. B. from 10 mm to 50 mm in length.

Aus der Druckschrift DE 20 2015 100 038 U1 ist ein spezieller S-Anschluss bekannt geworden, bei dem das mit dem 1/2"-Außengewinde versehene Ende wesentlich länger ausgeführt ist als üblich, so dass es bedarfsgerecht gekürzt werden kann. Auf diese Weise kann auf ein umständliches Aneinanderreihen von Hahnverlängerungen verzichtet werden. Damit der mit dem 1/2"-Außengewinde versehene Abschnitt auf das benötigte Maß gekürzt werden kann, muss das 1/2"-Außengewinde zylindrisch ausgeführt sein.From the publication DE 20 2015 100 038 U1 For example, a special S-fitting has become known in which the end provided with the 1/2 "male thread is made substantially longer than usual, so that it can be shortened as needed. In order to shorten the section provided with the 1/2 "male thread to the required size, the 1/2" male thread must be cylindrical.

Aus der Druckschrift DE 10 2013 205 250 A1 ist ein Rohranschlussadapter bekannt geworden, der ähnlich wie ein herkömmlicher S-Anschluss einen seitlichen Versatz ausgleichen kann. Hierzu weist der bekannte Rohanschlussadapter ein erstes Teil auf, das in eine Wandscheibe bzw. eine Hahnverlängerung eingeschraubt wird und an seinem davon abgewandten Ende scheibenförmig ausgebildet ist. Ein zweites Teil des bekannten Rohranschlussadapters, das mit der Armatur verbunden wird, umschließt den scheibenförmigen Abschnitt fluiddicht und kann in der Ebene der Scheibe verschoben werden. Ein Überbrücken unterschiedlich großer Abstände zwischen Armatur und Wandscheibe ist mit dem bekannten Rohranschlussadapter nicht möglich.From the publication DE 10 2013 205 250 A1 has become known a pipe connection adapter, which can compensate for a lateral offset similar to a conventional S-port. For this purpose, the known Rohanschlussadapter on a first part which is screwed into a wall plate or a Hahnverlängerung and is disc-shaped at its end facing away from it. A second part of the known pipe connection adapter, which is connected to the fitting, surrounds the disk-shaped portion fluid-tight and can be moved in the plane of the disk. A bridging different distances between the valve and wall plate is not possible with the known pipe connection adapter.

Aus der Druckschrift DE 20 2014 006 320 U1 ist ein S-Anschluss bekannt geworden, der wie ein herkömmlicher S-Anschluss mit einem Ende in eine Wandscheibe bzw. eine Hahnverlängerung eingeschraubt wird. An dem anderen Ende, das zur Verbindung mit der Armatur vorgesehen ist, befindet sich ein Adapter, der in Axialrichtung verstellbar angebracht ist. Durch Verschieben des Adapters kann die Gesamtlänge der Vorrichtung in einem gewissen Rahmen an einen gegebenen Abstand zwischen Wandscheibe und Armatur angepasst werden.From the publication DE 20 2014 006 320 U1 is known S-connection, which is screwed like a conventional S-connection with one end in a wall disk or a Hahnverlängerung. At the other end, which is provided for connection to the fitting, there is an adapter which is mounted adjustable in the axial direction. By moving the adapter, the Overall length of the device can be adjusted in a certain frame to a given distance between wall plate and fitting.

Davon ausgehend ist es die Aufgabe der Erfindung, einen S-Anschluss zum Anschließen einer Armatur an eine Wasserleitung zur Verfügung zu stellen, der einfach an einen gegebenen Abstand zwischen Armatur und Wasserleitung angepasst werden kann und eine einfache und zuverlässige Abdichtung ermöglicht.On this basis, it is the object of the invention to provide an S-connection for connecting a fitting to a water pipe, which can be easily adapted to a given distance between the fitting and the water pipe and allows easy and reliable sealing.

Diese Aufgabe wird gelöst durch den S-Anschluss mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind in den sich anschließenden Unteransprüchen angegeben.This object is achieved by the S-connection with the features of claim 1. Advantageous embodiments are specified in the subsequent subclaims.

Der S-Anschluss dient zum Anschließen einer Armatur an eine Wasserleitung und hat

  • ein S-Stück, das ein 3/4"-Außengewinde zur Verbindung mit einer Armatur und ein Innengewinde aufweist, wobei eine Längsachse des 3/4"-Außengewindes und eine Längsachse des Innengewindes parallel und in einem Abstand voneinander angeordnet sind, und
  • ein Rohrstück, das einen wasserleitungsseitigen Abschnitt mit einem 1/2"-Außengewinde zur Verbindung mit einer Wasserleitung und einen S-Stück-seitigen Abschnitt aufweist, der ein Außengewinde mit einer Länge von mindestens 30mm aufweist, das in das Innengewinde des S-Stücks einschraubbar ist.
The S connection is used to connect a fitting to a water pipe and has
  • an S-piece having a 3/4 "male thread for connection to a fitting and an internal thread, wherein a longitudinal axis of the 3/4" male thread and a longitudinal axis of the female thread are arranged parallel and at a distance from each other, and
  • a pipe section having a water pipe side portion with a 1/2 "male thread for connection to a water pipe, and an S-piece side portion having an external thread with a length of at least 30mm, which can be screwed into the female thread of the S-piece is.

Das S-Stück kann ähnlich geformt sein wie ein herkömmlicher S-Anschluss. Insbesondere weist es ein 3/4"-Außengewinde auf, das in der von herkömmlichen S-Anschlüssen bekannten Weise mit der Armatur verbunden wird. Dies geschieht zum Beispiel mit einer an der Armatur vorgesehenen Überwurfmutter, die auf das 3/4"-Außengewinde des S-Stücks aufgeschraubt wird und eine Dichtfläche der Armatur mit einer Stirnseite des S-Stücks verspannt. Die Abdichtung erfolgt hier also in der Regel nicht im Bereich des Gewindes, sondern an der Stirnseite des S-Stücks an dem mit dem 3/4"-Außengewinde versehenen Ende.The S-piece can be shaped similar to a conventional S-connector. In particular, it has a 3/4 "male thread, which is connected to the fitting in the manner known from conventional S-type connections, for example with a union nut provided on the fitting, which fits onto the 3/4" male thread of the fitting S-piece is screwed on and clamped a sealing surface of the valve with a front side of the S-piece. The seal is done here so in the Usually not in the area of the thread, but on the front side of the S-piece at the end provided with the 3/4 "male thread.

Der seitliche Versatz wird durch den Abstand zwischen den Längsachsen des 3/4"-Außengewinde einerseits und des Innengewindes des S-Stücks andererseits bewirkt. Die seitliche Anordnung des 3/4"-Außengewindes des S-Stücks kann somit wie bei herkömmlichen S-Anschlüssen durch Verdrehen des S-Stücks justiert werden.The lateral offset is caused by the distance between the longitudinal axes of the 3/4 "male thread on the one hand and the female thread of the S piece on the other hand, thus allowing the side of the 3/4" male thread of the S-piece to be similar to conventional S-type fittings be adjusted by twisting the S-piece.

Bei der Erfindung gibt es zusätzlich zu dem S-Stück ein Rohrstück, das für die Anpassbarkeit der Länge des gesamten S-Anschlusses zuständig ist. Das Rohrstück kann gerade und vollständig rotationssymmetrisch ausgebildet sein. Es weist ein 1/2"-Außengewinde zur Verbindung mit einer Wasserleitung auf, das insbesondere unmittelbar in eine Wandscheibe eingeschraubt werden kann. Natürlich kann das 1/2"-Außengewinde des Rohrstücks auch in der von herkömmlichen S-Anschlüssen bekannten Weise mit einer Hahnverlängerung verschraubt werden, falls der Abstand zwischen Wandscheibe und Armatur so groß ist, er nicht vollständig von dem S-Anschluss überbrückt werden kann.In the invention, in addition to the S-piece there is a piece of pipe which is responsible for the adaptability of the length of the entire S-connection. The pipe section can be straight and completely rotationally symmetrical. It has a 1/2 "male thread for connection to a water pipe which, in particular, can be screwed directly into a wall disk, of course the 1/2" male thread of the pipe piece can also be in the manner known from conventional S-type fittings with a tap extension be bolted, if the distance between the wall plate and fitting is so large that it can not be completely bridged by the S-port.

Zusätzlich zu dem 1/2"-Außengewinde zur Verbindung mit einer Wasserleitung weist das Rohrstück ein S-Stück-seitigen Abschnitt auf, der ein Außengewinde aufweist, das in das Innengewinde des S-Stücks einschraubbar ist. Eine Längsachse dieses Außengewindes kann mit der Längsachse des 1/2"-Außengewindes zur Verbindung mit der Wasserleitung zusammenfallen.In addition to the 1/2 "male thread for connection to a water pipe, the pipe piece has an S-piece side portion which has an external thread which can be screwed into the internal thread of the S-piece of the 1/2 "male thread for connection to the water line.

Das Außengewinde des S-Stück-seitigen Abschnitts des Rohrstücks ist in das Innengewinde des S-Stücks einschraubbar, wobei eine zuverlässige Abdichtung im Bereich dieser Gewindeverbindung beispielsweise unter Zuhilfenahme eines Dichtmittels wie Hanf oder Dichtband hergestellt werden kann. Sind S-Stück und Rohrstück in dieser Weise miteinander verbunden, stellt der erfindungsgemäße S-Anschluss wie ein herkömmlicher S-Anschluss an einem Ende ein 3/4"-Außengewinde zur Verbindung mit der Armatur und an dem anderen Ende ein 1/2"-Außengewinde zur Verbindung mit der Wasserleitung zur Verfügung. Anders als bei einem herkömmlichen S-Anschluss kann die seitliche Verstellbarkeit einerseits durch Verdrehen des Rohrstücks relativ zu der Wasserleitung, andererseits durch Verdrehen des S-Stücks relativ zu dem Rohrstück realisiert werden.The external thread of the S-piece-side portion of the pipe section can be screwed into the internal thread of the S-piece, wherein a reliable seal in the region of this threaded connection can be made for example with the aid of a sealant such as hemp or sealing tape. If the S-piece and the tube piece are connected in this way, the S-connection according to the invention, like a conventional S-connection, forms a 3/4 "male thread at one end In contrast to a conventional S-connection, the lateral adjustability can be achieved by twisting the pipe section relative to the water pipe, on the one hand, and by twisting the pipe, on the other hand S-piece relative to the pipe piece can be realized.

Ein weiterer Vorteil des erfindungsgemäßen S-Anschlusses ist, dass die Gesamtlänge durch bedarfsgerechtes Kürzen des S-Stück-seitigen Abschnitts des Rohrstücks einfach an einen gegebenen Abstand zwischen Wasserleitung und Armatur angepasst werden kann. Dabei lässt das Kürzen des S-Stück-seitigen Abschnitts die Verbindungen zwischen dem wasserleitungsseitigen Abschnitt und der Wasserleitung einerseits und dem 3/4"-Außengewinde und der Armatur andererseits völlig unberührt. Diese Verbindungen können in der gewohnten Weise hergestellt werden.Another advantage of the S-connection according to the invention is that the total length can be easily adapted to a given distance between the water pipe and the fitting by shortening the S-piece-side portion of the pipe section as needed. The shortening of the S-piece side section leaves the connections between the water-line-side section and the water pipe on the one hand and the 3/4 "male thread and the fitting completely unaffected on the other hand.These connections can be made in the usual way.

Das Herstellen der flüssigkeitsdichten Verbindung zwischen Rohrstück und S-Stück kann hingegen insbesondere vor der Montage an der Wasserleitung erfolgen, so dass der abzudichtende Verbindungsbereich besonders gut zugänglich ist. Fehler bei der Abdichtung können dabei vermieden werden.On the other hand, the liquid-tight connection between the pipe section and the S-piece can be produced, in particular, prior to installation on the water line, so that the connection region to be sealed is particularly easily accessible. Errors in the seal can be avoided.

Das Außengewinde des S-Stück-seitigen Rohrstücks weist eine Länge von mindestens 30mm auf. Für die Verbindung zwischen Rohrstück und S-Stück ist es ausreichend, das Außengewinde des S-Stück-seitigen Abschnitts des Rohrstücks etwa 8 mm bis 15 mm tief in das Innengewinde des S-Stücks einzuschrauben. Die darüber hinausgehende Länge kann somit ohne weiteres gekürzt werden, um die Gesamtlänge des S-Anschlusses in der gewünschten Weise anzupassen. Das Kürzen kann stufenlos und millimetergenau erfolgen, so dass stets eine exakte Positionierung des 3/4"-Außengewindes möglich ist.The external thread of the S-piece-side pipe section has a length of at least 30mm. For the connection between pipe piece and S-piece, it is sufficient to screw the external thread of the S-piece-side portion of the pipe section about 8 mm to 15 mm deep into the internal thread of the S-piece. The excess length can thus be easily shortened to adjust the overall length of the S-terminal in the desired manner. Shortening can be infinitely variable and accurate to the millimeter, so that an exact positioning of the 3/4 "male thread is always possible.

In einer Ausgestaltung weisen das 1/2"-Außengewinde des wasserleitungsseitigen Abschnitts des Rohrstücks und das Außengewinde des S-Stück-seitigen Abschnitts des Rohrstücks einen Abstand voneinander von 10 mm oder weniger auf. Der Abstand kann auch noch kleiner gewählt werden und beispielsweise weniger als 5 mm oder weniger als 2 mm betragen. Die beiden Gewinde können auch unmittelbar aneinander angrenzen oder ineinander übergehen. Je geringer der Abstand zwischen den beiden Gewinden, desto stärker kann das Rohrstück gekürzt werden.In one embodiment, the 1/2 "male thread of the water pipe side portion of the pipe piece and the male thread of the S piece side portion of the pipe piece are spaced apart by 10 mm or less, and the distance may be even smaller, for example less than 5 mm or less than 2 mm.The two threads can also be directly adjacent to each other or merge into each other.The smaller the distance between the two threads, the more the pipe section can be shortened.

In einer Ausgestaltung ist das 1/2"-Außengewinde des wasserleitungsseitigen Abschnitts des Rohrstücks ein kegeliges Gewinde. Insbesondere kann dieses Gewinde gemäß der Norm EN10226 und/oder DIN2999 ausgeführt sein. Bei einem kegeligen Außengewinde nimmt der Außendurchmesser des Gewindes mit zunehmenden Abstand von dem wasserleitungsseitigen Ende des wasserleitungsseitigen Abschnitts geringfügig zu, so dass beim Einschrauben in ein zylindrisches Innengewinde einer Wandscheibe eine metallische Dichtung erzielt wird. Anders als bei dem eingangs geschilderten, aus der Druckschrift DE 20 2015 100 038 U1 bekannten S-Anschluss, der ebenfalls ein kürzbares Außengewinde aufweist, ist mit dem erfindungsgemäßen S-Anschluss also eine als besonders sicher geltende, metallische Dichtung zwischen S-Anschluss und Wandscheibe möglich. Dies ist von besonderer Bedeutung, weil gerade diese Verbindung besonders tief innerhalb der Wand angeordnet ist, so dass eine Leckage besonders schwer zu entdecken und zu beheben ist. Bei Undichtigkeiten in diesem Bereich entstehen häufig besonders große Wasserschäden.In one embodiment, the 1/2 "male thread of the water pipe side portion of the pipe piece is a tapered thread, in particular, this thread can be made according to EN10226 and / or DIN2999 standard Slightly close to the end of the water-line-side section, so that when screwed into a cylindrical internal thread of a wall plate, a metallic seal is achieved, unlike the above-mentioned, from the document DE 20 2015 100 038 U1 known S-terminal, which also has a shortened external thread, is thus possible with the S-connection according to the invention as a particularly safe, metallic seal between S-port and wall plate. This is of particular importance because it is precisely this connection that is located particularly deep inside the wall so that leakage is particularly difficult to detect and correct. Leakage in this area often causes particularly large water damage.

In einer Ausgestaltung ist das Außengewinde des S-Stück-seitigen Abschnitts des Rohrstücks ein zylindrisches Gewinde. Bei einem zylindrischen Gewinde ist der Außendurchmesser des Gewindes über die gesamte Länge des Außengewindes konstant. Bei der vorgesehenen Kürzung des Außengewindes des S-Stück-seitigen Abschnitts ändert sich an der Schraubverbindung zwischen Rohrstück und S-Stück daher nichts.In one embodiment, the external thread of the S-piece side portion of the pipe section is a cylindrical thread. In a cylindrical thread, the outer diameter of the thread is constant over the entire length of the external thread. With the intended shortening of the external thread of the S-piece-side section, therefore, nothing changes at the screw connection between pipe piece and S-piece.

In einer Ausgestaltung ist das Innengewinde des S-Stücks ein zylindrisches Gewinde. Dies ist für die Schraubverbindung mit dem Außengewinde des S-Stück-seitigen Abschnitts des Rohrstücks besonders einfach, wobei die Abdichtung wie üblich unter Zuhilfenahme eines Dichtmittels erfolgen kann.In one embodiment, the internal thread of the S-piece is a cylindrical thread. This is particularly easy for the screw with the external thread of the S-piece-side portion of the pipe section, the seal can be done as usual with the aid of a sealant.

In einer Ausgestaltung ist das Innengewinde des S-Stücks ein kegeliges Gewinde. Dieses kann ebenfalls einer der oben genannten Normen entsprechen. Es weist einen mit zunehmendem Abstand von dem dem Rohrstück zugewandten Ende des S-Stücks geringfügig abnehmenden Innendurchmesser auf, so dass beim Einschrauben des Rohrstücks ebenfalls eine metallische Dichtung erzielt wird, die als besonders zuverlässig gilt.In one embodiment, the internal thread of the S-piece is a tapered thread. This may also comply with one of the above standards. It has a with increasing distance from the pipe piece facing the end of the S-piece slightly decreasing inner diameter, so that when screwing the pipe piece also a metallic seal is achieved, which is considered particularly reliable.

In weiteren Ausgestaltungen weist das Außengewinde des S-Stücks-seitigen Abschnitts des Rohrstücks eine Länge von mindestens 50 mm oder von mindestens 80 mm auf. Dadurch können auch größere Abstände zwischen Wasserleitung und Armatur überbrückt werden. Gleichzeitig ist ein Kürzen des Rohrstücks in einem noch größeren Maße möglich, so dass in den allermeisten Einbausituationen auf die zusätzliche Verwendung einer Hahnverlängerung verzichtet werden kann.In further embodiments, the external thread of the S-piece side portion of the pipe section has a length of at least 50 mm or at least 80 mm. As a result, larger distances between the water pipe and fitting can be bridged. At the same time a shortening of the pipe section is possible to an even greater extent, so that in the vast majority of installation situations can be dispensed with the additional use of a tap extension.

In einer Ausgestaltung sind das Außengewinde des S-Stück-seitigen Abschnitts des Rohrstücks und das Innengewinde des S-Stücks 1/2" Gewinde. Grundsätzlich sind auch andere Durchmesser möglich. Bei einem 1/2" Gewinde sind S-Stück und Rohrstück besonders kompakt aufgebaut und ermöglichen einen optimalen Durchfluss.In one embodiment, the male thread of the S-piece side portion of the pipe fitting and the female thread of the S-piece are 1/2 "threads., Other diameters are generally possible built and allow optimal flow.

In einer Ausgestaltung weist das S-Stück eine Gesamtlänge von 40 mm oder weniger auf. Beispielsweise kann die Gesamtlänge des S-Stücks im Bereich von 25 mm bis 40 mm, bevorzugt im Bereich von 30 mm bis 35 mm liegen. Durch einen entsprechend kurzen Aufbau des S-Stücks kann die Gesamtlänge des S-Anschlusses besonders kurz gehalten werden. Ein weiterer Vorteil besteht darin, dass die Verbindung zwischen Rohrstück und S-Stück außerhalb der Wand liegen kann, beispielsweise vor der Ebene einer Oberfläche von auf die Wand aufgebrachten Fliesen. Eine Undichtigkeit im Verbindungsbereich zwischen S-Stück und Rohrstück kann dadurch besonders einfach bemerkt und beseitigt werden. Die Gefahr, dass in diesem Bereich austretendes Wasser unbemerkt im Inneren der Wand versickert und langfristig einen großen Schaden verursacht, wird reduziert.In one embodiment, the S-piece has a total length of 40 mm or less. For example, the total length of the S-piece may be in the range of 25 mm to 40 mm, preferably in the range of 30 mm to 35 mm. By a correspondingly short construction of the S-piece, the total length of the S-connection can be kept particularly short. Another advantage is that the connection between the pipe section and S-piece can be outside the wall, for example, in front of the level of a surface of applied to the wall tiles. A leak in the connection area between the S-piece and pipe section can be particularly easily noticed and eliminated. The risk of leaking water inside the wall unnoticed in this area and causing long-term damage is reduced.

In einer Ausgestaltung weist das S-Stück einen armaturseitigen Abschnitt, der das 3/4"-Außengewinde aufweist, einen rohrstückseitigen Abschnitt, der das Innengewinde aufweist, und einen mittleren Abschnitt, der einen Übergang zwischen dem armaturseitigen Abschnitt dem rohrstückseitigen Abschnitt bildet, auf. Der seitliche Versatz der Längsachsen zwischen den beiden Gewinden des S-Stücks wird durch den mittleren Abschnitt realisiert.In one embodiment, the S-piece has a fitting-side portion having the 3/4 "male thread, a pipe piece-side portion having the female thread, and a middle portion forming a transition between the fitting-side portion and the pipe-piece-side portion. The lateral offset of the longitudinal axes between the two threads of the S-piece is realized by the middle section.

In einer Ausgestaltung beträgt die Länge des mittleren Abschnitts 10 mm oder weniger. Dies begünstigt einen besonders kurzseitigen Aufbau des S-Stücks.In one embodiment, the length of the middle section is 10 mm or less. This favors a particularly short-sided construction of the S-piece.

In einer Ausgestaltung beträgt die Länge des Innengewinde des S-Stücks 15 mm oder weniger. Damit ist das Innengewinde so bemessen, das eine zuverlässige Abdichtung gegenüber dem Außengewinde des Rohrstücks möglich ist. Hierzu kann auch eine Länge des Innengewindes im Bereich von 8 mm bis 15 mm, insbesondere im Bereich von 8 mm bis 12 mm oder von etwa 10 mm ausreichend sein. Bei einem entsprechend kurz ausgeführten Innengewinde des S-Stücks kann das S-Stück insgesamt ebenfalls besonders kurz ausgeführt werden.In one embodiment, the length of the female thread of the S-piece is 15 mm or less. Thus, the internal thread is sized so that a reliable seal against the external thread of the pipe section is possible. For this purpose, a length of the internal thread in the range of 8 mm to 15 mm, in particular in the range of 8 mm to 12 mm or of about 10 mm may be sufficient. With a correspondingly short internal thread of the S-piece, the S-piece can also be made very short overall.

In einer Ausgestaltung liegt der Abstand zwischen den Längsachsen im Bereich von 3 mm bis 40 mm. Eine Verstellbarkeit in diesem Bereich, bevorzugt im Bereich von 5 mm bis 20 mm, ist für die erforderliche, seitliche Justierung der Anordnung des 3/4"-Außengewindes in der Regel ausreichend.In one embodiment, the distance between the longitudinal axes is in the range of 3 mm to 40 mm. An adjustability in this range, preferably in the range of 5 mm to 20 mm, is usually sufficient for the required lateral adjustment of the arrangement of the 3/4 "male thread.

In einer Ausgestaltung weist das S-Stück zusätzlich zu dem Innengewinde ein 1/2"-Innengewinde auf, das konzentrisch zu dem 3/4"-Außengewinde angeordnet ist. Dadurch eignet sich der S-Anschluss nicht nur zum Anschließen einer Armatur an das 3/4"-Außengewinde in der vorstehend erläuterten Weise, sondern kann auch zur Verbindung beispielsweise mit einem Eckventil, das in das konzentrisch zu dem 3/4"-Außengewinde angeordnete ein 1/2"-Innengewinde eingeschraubt wird, verwendet werden. Dadurch kann auch die seitlich Anordnung eines solchen Eckventils sowie dessen Abstand zur Wasserleitung mit Hilfe des S-Anschlusses angepasst werden.In one embodiment, in addition to the female thread, the S-piece has a 1/2 "female thread concentric with the 3/4" male thread. As a result, the S port is not only suitable for connecting a fitting to the 3/4 "male thread in the manner described above, but may also be used for connection to, for example, an angle valve located in the concentric with the 3/4" male thread This also allows the lateral arrangement of such an angle valve and its distance to the water pipe with the aid of the S-connection can be adjusted.

In einer Ausgestaltung weist das Außengewinde des S-Stück-seitigen Abschnitts eine Riffelung auf. Dies kann eine Abdichtung mit einem Dichtmittel wie Hanf oder Dichtband beim Einschrauben vereinfachen.In one embodiment, the external thread of the S-piece-side portion on a corrugation. This can facilitate sealing with a sealant such as hemp or sealing tape when screwing.

In einer Ausgestaltung ist der S-Stück-seitige Abschnitt mit einer Rohrsäge kürzbar. Das Kürzen mit einer Rohrsäge ist besonders einfach und mit einer ausreichenden Genauigkeit ohne spezielles Werkzeug möglich.In one embodiment, the S-piece-side section can be shortened with a pipe saw. Shortening with a pipe saw is particularly easy and possible with sufficient accuracy without special tools.

Grundsätzlich kann der S-Anschluss aus allen im Sanitärbereich einsetzbaren Materialien hergestellt werden. In einer Ausgestaltung besteht der S-Anschluss aus Messing und oder ist verchromt. Er ist dadurch besonders langlebig. Ebenfalls verwendet werden können Rotguss oder Edelstahl.In principle, the S connection can be made from all materials that can be used in the sanitary sector. In one embodiment, the S-port is made of brass and or is chrome plated. He is thus particularly durable. Also used can be gunmetal or stainless steel.

The invention will be explained in more detail with reference to embodiments shown in FIGS. Show it:
Fig. 1
an S-port in a simplified sectional view,
Fig. 2
the S port off Fig. 2 in the mounted state on a water pipe, also in a simplified sectional view.

Der in Fig. 1 dargestellte S-Anschluss besteht aus einem S-Stück 10 und einem Rohrstück 12, ist also zweiteilig. Das S-Stück 10 weist drei Längsabschnitte auf, nämlich einen armaturseitigen Abschnitt 14, einen rohrstückseitigen Abschnitt 16 und einen mittleren Abschnitt 18. Der mittlere Abschnitt 18 bildet einen Übergang zwischen dem armaturseitigen Abschnitt 14 und dem rohrstückseitigen Abschnitt 16.The in Fig. 1 shown S-port consists of an S-piece 10 and a pipe section 12, so it is in two parts. The S-piece 10 has three longitudinal sections, namely a fitting-side section 14, a pipe piece-side section 16 and a middle section 18. The middle section 18 forms a transition between the fitting-side section 14 and the pipe-piece-side section 16.

Der armaturseitige Abschnitt 14 weist ein 3/4"-Außengewinde 20 auf, das sich im Wesentlichen über die gesamte Länge des armaturseitigen Abschnitts 14 erstreckt und eine Längsachse 22 aufweist. Der rohrstückseitige Abschnitt 16 weist ein Innengewinde 24 auf, das sich im Wesentlichen über die gesamte Länge des rohrstückseitigen Abschnitts 16 erstreckt und eine Längsachse 26 aufweist. Die beiden Längsachsen 22, 26 sind parallel und in einem Abstand d voneinander angeordnet. Im dargestellten Beispiel beträgt der Abstand etwa 10 mm und das Innengewinde 24 hat einen Durchmesser von 1/2". Das Innengewinde 24 kann, wie dargestellt, zylindrisch sein. Alternativ kann an dieser Stelle ein kegeliges Innengewinde eingesetzt werden.The armature-side portion 14 has a 3/4 "male thread 20 which extends substantially the entire length of the armature-side portion 14 and has a longitudinal axis 22. The tubular-piece-side portion 16 has an internal thread 24 which extends substantially over the The two longitudinal axes 22, 26 are arranged parallel to each other and at a distance d from one another In the example shown, the distance is approximately 10 mm and the internal thread 24 has a diameter of 1/2 ". , The female thread 24 may be cylindrical, as shown. Alternatively, a tapered internal thread can be used at this point.

Die Gesamtlänge 1 des dargestellten S-Stücks 10 beträgt etwa 35 mm, wovon 10 mm oder weniger auf den mittleren Abschnitt 18 entfallen.The total length 1 of the illustrated S-piece 10 is about 35 mm, of which 10 mm or less accounts for the central portion 18.

Das Rohrstück 12 weist einen im Wesentlichen gleichmäßigen Innendurchmesser auf und hat eine Längsachse 28, zu der es vollständig rotationssymmetrisch ausgebildet ist. Das Rohrstück 12 hat einen S-Stück-seitigen Abschnitt 30, der ein zylindrisches Außengewinde 32 mit einer Länge von mindestens 30 mm aufweist. Der S-Stück-seitige Abschnitt 30 samt Außengewinde 32 ist beliebig kürzbar, beispielsweise mit einer Rohrsäge.The tube piece 12 has a substantially uniform inner diameter and has a longitudinal axis 28, to which it is completely rotationally symmetrical. The pipe section 12 has an S-piece side section 30, which has a cylindrical external thread 32 with a length of at least 30 mm. The S-piece-side section 30 together with external thread 32 can be shortened as desired, for example with a pipe saw.

Das Rohrstück 12 hat außerdem einen wasserleitungsseitigen Abschnitt 34 mit einem kegeligen 1/2"-Außengewinde 36, mit dem es mit einer Wasserleitung verbunden werden kann.The pipe section 12 also has a water pipe side portion 34 with a tapered 1/2 "male thread 36, with which it can be connected to a water pipe.

In Gebrauch wird das Rohrstück 12 im Bereich des Außengewindes 30 auf die benötigte Länge gekürzt und mit dem S-Stück 10 verbunden. Hierzu wird das Außengewinde 32 des S-Stück-seitigen Abschnitts 30 des Rohrstücks 12 in das Innengewinde 24 des S-Stücks 10 eingeschraubt, wobei ein Dichtmittel wie Hanf oder ein Dichtband hinzugefügt werden kann.In use, the pipe section 12 is shortened in the region of the external thread 30 to the required length and connected to the S-piece 10. For this purpose, the external thread 32 of the S-piece-side portion 30 of the pipe section 12 is screwed into the internal thread 24 of the S-piece 10, wherein a sealant such as hemp or a sealing tape can be added.

Fig. 2 zeigt den S-Anschluss aus Fig. 1 in einem typischen Einbauzustand. Dargestellt ist eine Wand 38, in der eine Wandscheibe 40 befestigt ist, die einen bauseitigen Abschluss einer nicht weiter dargestellten Wasserleitung darstellt. Die Wandscheibe 40 weist ein zylindrisches 1/2"-Innengewinde 42 auf. Fig. 2 shows the S port Fig. 1 in a typical state of installation. Shown is a wall 38, in which a wall plate 40 is fixed, which represents an on-site completion of a water pipe not shown. The wall plate 40 has a cylindrical 1/2 "internal thread 42.

Vor der Montage des S-Anschlusses wird die gegebene Einbautiefe s der Wandscheibe 40 in der Wand 38 gemessen, beispielsweise von einer Stirnfläche 44 der Wandscheibe 40 bis zu einer Vorderseite 46 der Wand 38 entsprechend beispielsweise der Vorderseite einer Fliese. Anschließend wird das Rohrstück 12 so gekürzt, dass die Gesamtlänge des S-Anschlusses an die Einbautiefe s und den gewünschten Abstand des 3/4"-Außengewindes zur Verbindung mit der Armatur von der Vorderseite der Wand 46 überbrückt wird, wenn es ordnungsgemäß in das Innengewinde 42 der Wandscheibe 40 eingeschraubt ist.Before mounting the S-terminal, the given installation depth s of the wall plate 40 in the wall 38 is measured, for example, from an end face 44 of the wall plate 40 to a front side 46 of the wall 38 corresponding to, for example, the front of a tile. Thereafter, the length of pipe 12 is trimmed so that the total length of the S-port is shunted to the mounting depth s and the desired distance of the 3/4 "male thread for connection to the fitting from the front of the wall 46 when properly seated 42 of the wall plate 40 is screwed.

Nach dem Kürzen des Rohrstücks 12 wird dieses unter Hinzunahme eines geeigneten Dichtmittels mit dem S-Stück 10 verschraubt und das kegelige 1/2"-Außengewinde 36 des wasserleitungsseitigen Abschnitts 34 des Rohstücks 12 wird in das Innengewinde 42 der Wandscheibe 40 fest eingeschraubt, so dass dort eine metallisch dichtende Verbindung entsteht.After shortening the pipe section 12, this is screwed with the addition of a suitable sealant with the S-piece 10 and the tapered 1/2 "-Außengewinde 36 of the water pipe side portion 34 of the blank 12 is firmly screwed into the internal thread 42 of the wall plate 40, so that there is a metallic sealing connection.

Anschließend kann eine Rosette 48 auf das 3/4"-Außengewinde 20 des S-Stücks 10 aufgeschraubt werden, so dass die Rosette 48 an der Oberfläche 46 der Wand 38 anliegt und ein für die Befestigung einer Armatur ausreichender Längsabschnitt des 3/4"-Außengewindes frei bleibt.Subsequently, a rosette 48 can be screwed onto the 3/4 "outer thread 20 of the S-piece 10 so that the rosette 48 rests against the surface 46 of the wall 38 and a longitudinal section of the 3/4" sufficient for attachment of a fitting. External thread remains free.
