Description

Die Erfindung betrifft eine Einrichtung zur Verbindung einer unter Putz verlegten flexiblen Doppel-Rohrleitung mit einem Gebrauchswasser-Verbraucher gemäss dem Oberbegriff des unabhängigen Patentanspruches 1.The invention relates to a device for connecting a plastered flexible double pipeline to a service water consumer according to the preamble of independent claim 1.

Die bekannten, zum Anschluss gebrauchswasserführender flexibler Kunststoff-Rohrleitungen dienenden Armaturen wurden zwecks Erleichterung des Montagevorganges insofern verbessert, als der zur Halterung des Anschlussstückes in der Wandaussparung dienende Dosenkörper geteilt wurde. Diese bekannte zweiteilige Anschlussdose, welche beispielsweise in der EP-A-0 191 309 beschrieben ist, weist aber den Nachteil auf, dass das Anschlussstück nur ausserhalb der Wandaussparung auf das flexible Kunststoffrohr aufgeschraubt werden kann, so dass das Kunststoffrohr zur Montage jeweils aus der Handaussparung herausgeschwenkt und anschliessend wieder an seinen ursprünglichen Platz in der Wandaussparung zurückversetzt werden muss.The known fittings used for the connection of flexible plastic pipelines carrying service water have been improved in order to facilitate the assembly process in that the socket body serving to hold the connection piece in the wall recess has been divided. However, this known two-part junction box, which is described, for example, in EP-A-0 191 309, has the disadvantage that the connector can only be screwed onto the flexible plastic tube outside the wall recess, so that the plastic tube for assembly is in each case removed from the hand recess swung out and then returned to its original place in the wall recess.

Durch die EP-A-00 85 329 ist ferner eine Anschlusseinrichtung für Armaturen bekannt, deren Anschlussdose einen im hinteren Teil einer Wandaussparung anzuordnenden Grundkörper und einen frontal auf denselben aufsteckbaren Deckel aufweist. Bei dieser bekannten Ausführung muss zunächst der Grundkörper der Anschlussdose montiert werden, worauf der Anschlusswinkel am Rohr befestigt und in den Grundkörper eingesetzt wird. Anschliessend wird der Deckel montiert und mit einem Sicherungsring befestigt.EP-A-00 85 329 also discloses a connection device for fittings, the connection box of which has a base body to be arranged in the rear part of a wall recess and a cover which can be plugged onto the same from the front. In this known embodiment, the base body of the junction box must first be installed, whereupon the connection bracket is attached to the pipe and inserted into the base body. The cover is then installed and secured with a locking ring.

In Anbetracht dieser Konstruktion ist es unmöglich, die Anschlussdose vom Herstellerwerk aus mit bereits vormontiertem Anschlusswinkel zu liefern, was für den Monteur mit einem erheblichen Zeitverlust verbunden ist. Auch lässt sich die bekannte Anschlusseinrichtung im Rahmen der heute üblichen Montage mit Montagelehre nur insofern einsetzen, als die Montagelehre nach beendeter Montage nicht mehr abgenommen werden kann und somit ins Mauerwerk integriert werden muss.In view of this construction, it is impossible to deliver the junction box from the manufacturer's factory with the connection bracket already preassembled, which means that the installer wastes a considerable amount of time. Also, the known connection device can only be used in the context of today's assembly with assembly jig, insofar as the assembly jig can no longer be removed after the assembly has been completed and must therefore be integrated into the masonry.

Es ist die Aufgabe der vorliegenden Erfindung, eine Anschlusseinrichtung der beschriebenen Art vorzuschlagen, welche es gestattet, das flexible Kunststoffrohr innerhalb der Wandaussparung an das im Dosenkörper vormontierte Anschlussstück anzuschliessen. Dadurch braucht das wasserführende Kunststoffrohr nicht mehr aus der Wandaussparung herausgeschwenkt zu werden.It is the object of the present invention to propose a connection device of the type described, which allows the flexible plastic tube to be connected within the wall recess to the connection piece pre-assembled in the socket body. As a result, the water-carrying plastic pipe no longer needs to be pivoted out of the wall recess.

Die den Gegenstand der Erfindung bildende Einrichtung ist im unabhängigen Patentanspruch 1 definiert, wobei bevorzugte Ausführungsformen sich aus den abhängigen Ansprüchen ergeben.The device forming the subject of the invention is defined in independent claim 1, preferred embodiments resulting from the dependent claims.

Dank dieser Ausbildung der Anschlusseinrichtung kann der Dosenkörper vom Lieferwerk mit bereits vormontiertem Anschlussstück angeliefert werden, wobei ferner der Einsatz der heute üblichen schienenförmigen Montagelehren vereinfacht wird und die Montagelehre nach Gebrauch ohne weiteres wieder entfernt werden kann.Thanks to this design of the connection device, the box body can be delivered from the delivery plant with the connection piece already preassembled, the use of the rail-shaped assembly jigs customary today being simplified and the assembly jig being easily removed after use.

Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachstehend unter Bezugnahme auf die beiliegende Zeichnung beschrieben.

An embodiment of the subject matter of the invention is described below with reference to the accompanying drawings.
  • 1 is a sectional view of an embodiment of the device according to the invention in a first phase of the assembly process,
  • 2 to 4 show three further phases of assembly and the
  • 5 is a bottom view of the junction box body,
  • Fig. 6 is an end view of the junction box body and the
  • Fig. 7 is the front view of the connection bracket mounted in the junction box base.

Gemäss Fig. 1 befindet sich im oberen Abschnitt einer Wandaussparung der Grundkörper 1 einer Anschlussdose, in welchem sich ein vorgängig montiertes Anschlussstück 2 befindet. Das Anschlussstück 2 weist im Hinblick auf seine Befestigung einen peripheren Ringflansch 3 auf, der durch einen Schraubring 4 gegen eine im Dosen-Grundkörper 1 vorgesehene Schulter 5 gepresst und damit sicher gehalten wird.1, the base body 1 of a junction box is located in the upper section of a wall recess, in which there is a previously mounted connection piece 2. With regard to its attachment, the connection piece 2 has a peripheral ring flange 3, which is pressed by a screw ring 4 against a shoulder 5 provided in the base body 1 and is thus held securely.

Das Anschlussstück 2 ist bei diesem Ausführungsbeispiel ein 90°-Bogen und weist am oberen Ende ein Innengewinde 6, am unteren Ende ein Aussengewinde 7 auf. Das Innengewinde 6 dient zum Anschluss eines Wasserverbrauchers bzw. einer zu einem Wasserverbraucher führenden Leitung, während das Aussengewinde zum Anschluss an ein insgesamt mit 8 bezeichnetes flexibles Kunststoff-Doppelrohr vorgesehen ist. Im Hinblick auf die beabsichtigte Verbindung mit dem Doppelrohr 8 ragt der vertikale Ast des Anschlussstückes 2 um ein Mass a über die Unterkante des Grundkörpers 1 hinaus.In this exemplary embodiment, the connection piece 2 is a 90 ° bend and has an internal thread 6 at the upper end and an external thread 7 at the lower end. The internal thread 6 is used to connect a water consumer or a line leading to a water consumer, while the external thread is provided for connection to a flexible plastic double pipe, designated overall by 8. With regard to the intended connection with the double tube 8, the vertical branch of the connection piece 2 projects a dimension a beyond the lower edge of the base body 1.

Die Fig. 5 zeigt den Anschlussdosen-Grundkörper 1, von seiner Unterseite her gesehen, mit eingebautem Anschlussstück 2. Der aus einem verschleissfesten Kunststoff einteilig erstellte Grundkörper 1 weist an seiner durch Versteifungsrippen 19 verstärkten Innenwand zwei einander gegenüberliegende Stütznockenpaare 20 sowie eine untere, praktisch rechteckförmige Ausnehmung 21 auf. In die Ausnehmung 21 ragt eine am Anschlussstück 2 angegossene Anschlagschulter 22, die so auf die Ausnehmung 21 abgestimmt ist, dass sie satt in derselben an deren Konturen anliegt. Auch die Stütznocken 20 sind so angeordnet, dass sie am Umfang des Anschlussstücks 2 satt anliegen. Dank dieser Anordnung werden die bei der Montage des Armaturanschlusses am Anschlussstück 2 auftretenden Drehmomente einwandfrei in den Grundkörper 1 eingeleitet und können von diesem auf die angrenzende Wand übertragen werden, ohne dass der Kunststoff-Grundkörper 1 überbeansprucht wird.5 shows the junction box base body 1, seen from its underside, with built-in connection piece 2. The base body 1, which is made in one piece from a wear-resistant plastic, has two opposing pairs of support cams 20 on its inner wall reinforced by stiffening ribs 19 and a lower, practically rectangular one Recess 21 on. A stop shoulder 22 cast onto the connecting piece 2 projects into the recess 21 and is matched to the recess 21 in such a way that it fits snugly against the contours thereof. The support cams 20 are also arranged such that they lie snugly against the circumference of the connecting piece 2. Thanks to this arrangement, the torques which occur when the valve connection is mounted on the connecting piece 2 are properly introduced into the base body 1 and can be transferred from this to the adjacent wall without the plastic base body 1 being overstressed.

Im Hinblick auf die einwandfreie Uebertragung des Montage-Drehmoment es ist auch die obere Frontseite des Grundkörpers 1 gestaltet. Wie Fig. 6 zeigt, sind an der Innenwand des Grundkörpers 1 mehrere radial nach innen ragende Nocken 23 angeformt, die oberhalb eines kreisbogenförmigen Absatzes 24 mehrere seitliche Ausnehmungen 25 sowie eine untere Ausnehmung 25a begrenzen. Das in Fig. 7 dargestellte winkelförmige Anschlussstück 2 weist in seinem oberen Abschnitt den radial nach aussen ragenden Flansch 3 auf, dessen durch Kerben 27 getrennte Profile 28, 28a in Form und Grösse den Ausnehmungen 25 bzw. 25a des Grundkörpers angepasst sind, so dass sich der Flansch 3 satt in die Konturen des Grundkörpers 1 einsetzen lässt und somit ebenfalls eine risikolose Drehmomentenübertragung gewährleistet.With regard to the flawless transmission of the assembly torque, the upper front side of the base body 1 is also designed. As shown in FIG. 6, a plurality of radially inwardly projecting cams 23 are formed on the inner wall of the base body 1, said cams delimiting a plurality of lateral recesses 25 and a lower recess 25a above an arcuate shoulder 24. 7 has in its upper section the radially outwardly projecting flange 3, the profiles 28, 28a of which are separated by notches 27 in shape and size are adapted to the recesses 25 and 25a of the base body, so that the flange 3 fits snugly into the contours of the base body 1 and thus also ensures risk-free torque transmission.

Das vorzugsweise unter Putz verlegte Doppelrohr 8 weist in bekannter Weise ein an einen nicht gezeichneten Verteiler angeschlossenes wasserführendes Innenrohr 9 auf, das von einem Leerrohr 10 umgeben ist. Das Innenrohrwird zunächst um den strichpunktiert angedeuteten Endabschnitt verkürzt, so dass dessen Stirnfläche 9a in etwa an der unteren Stirnfläche 11 des Anschlussstücks 2 anliegt, wie dies Fig. 2 zeigt.The double pipe 8, which is preferably laid under plaster, has, in a known manner, a water-carrying inner pipe 9 which is connected to a distributor (not shown) and is surrounded by an empty pipe 10. The inner tube is first shortened by the end section indicated by dash-dotted lines, so that its end face 9a abuts approximately on the lower end face 11 of the connecting piece 2, as shown in FIG. 2.

Nun wird gemäss Fig. 3 ein Dosenfuss 12 von oben auf das Doppelrohr 8 aufgeschoben und anschliessend am oberen Ende des Innenrohres ein Kupplungsstück 13 angebracht. Die Montage dieses Kupplungsstücks 13 kann auf bekannte Weise entweder manuell oder mittels einer bekannten Spezialvorrichtung erfolgen (gemäss EP-A-0 219 661). Dabei wird auf das Innenrohr 9 eine Hülse 14 aufgepresst, deren vordere Aufbördelung als Anschlag für eine Ueberwurfmutter 15 dient.3, a can base 12 is pushed onto the double tube 8 from above and then a coupling piece 13 is attached to the upper end of the inner tube. This coupling piece 13 can be assembled in a known manner either manually or using a known special device (according to EP-A-0 219 661). In this case, a sleeve 14 is pressed onto the inner tube 9, the front flanging of which serves as a stop for a union nut 15.

In der letzten, in Fig. 4 dargestellten Phase des Montagevorganges wird nun das so vorbereitete Doppelrohr 8 in eine zum Gewinde 7 koaxiale Lage gebracht, worauf die Ueberwurfmutter 15 auf das Aussengewinde 7 des Anschlussstückes 2 im Sinne des Pfeiles aufgeschraubt wird.In the last phase of the assembly process, shown in FIG. 4, the double tube 8 thus prepared is brought into a position coaxial with the thread 7, whereupon the union nut 15 is screwed onto the external thread 7 of the connection piece 2 in the direction of the arrow.

Am Schluss wird der Dosenfuss 12 am Dosen-Grundkörper 1 angesetzt. Der demontierbare Dosenfuss 12 ermöglicht eine Kontrolle des Anschluss-Fittings bei der Druckprüfung.Finally, the can base 12 is attached to the can body 1. The removable can base 12 enables the connection fittings to be checked during the pressure test.

Damit ist die Anschlusseinrichtung fertig montiert, ohne dass es notwendig war, das Anschlussstück 2 zwecks Anbringung des Kupplungsstückes 13 aus der Wandaussparung herauszuschwenken. Es dürfte sich klar aus der vorangehenden Beschreibung ergeben, dass diese Montage ohne weiteres durch eine einzige Person ausgeführt werden kann.The connecting device is thus fully assembled without it being necessary to pivot the connecting piece 2 out of the wall recess for the purpose of attaching the coupling piece 13. It should be clear from the above description that this assembly can easily be carried out by a single person.

Der Dosen-Grundkörper 1 kann auf seiner dem Schraubring 4 gegenüberliegenden Seite mit einem abnehmbaren Deckel 16 versehen sein; dadurch lässt sich die beschriebene Vorrichtung auch für 180°-Anschlussstücke 17 verwenden, wie dies in Fig. 4 strichpunktiert angedeutet ist.The can body 1 can be provided on its side opposite the screw ring 4 with a removable cover 16; as a result, the device described can also be used for 180 ° connecting pieces 17, as is indicated by dash-dotted lines in FIG. 4.

Wie die Fig. 3 und 4 zeigen, ist der Dosenfuss 12 bei der gewählten Ausführungsform ein den Kupplungsbereich umgebender zylindrischer Körper 12a, dessen unterer, mit 12b bezeichneter Abschnitt dem Aussendurchmesser des Leerrohrs 10 angepasst ist. Die Kupplung des Dosenfusses 12 mit dem Grundkörper 1 kann an der mit 18 bezeichneten Stelle über eine bekannte Arretierungsvorrichtung, beispielsweise einen Bajonettverschluss, erfolgen.3 and 4 show, the can base 12 in the selected embodiment is a cylindrical body 12a surrounding the coupling area, the lower portion of which, designated by 12b, is adapted to the outer diameter of the empty tube 10. The can base 12 can be coupled to the base body 1 at the point denoted by 18 using a known locking device, for example a bayonet lock.

Die Ablängung des in Fig. 1 strichpunktiert gezeichneten Innenrohrabschnitts kann beispielsweise durch Bezugnahme auf die Achse x - x (z.B. Montageschiene) erfolgen, wobei dann, von dieser Achse ausgehend, das Innenrohr 9 um das Mass h zu verkürzen ist.The inner tube section shown in dash-dotted lines in FIG. 1 can be cut to length, for example, by reference to the axis x - x (e.g. mounting rail), the inner tube 9 then having to be shortened by the dimension h starting from this axis.
