Description

Die Erfindung bezieht sich auf eine Ablaufrutsche für eine Revisionsöffnung eines sanitären Einbaureservoirs. Die Erfindung bezieht sich weiterhin auf eine sanitäre Unterputzeinrichtung, die das sanitäre Einbaureservoir in Kombination mit der Ablaufrutsche umfasst.The invention relates to a chute for a revision opening of a sanitary installation reservoir. The invention further relates to a sanitary flushing device comprising the sanitary built-in reservoir in combination with the drainage chute.

Unter dem Begriff "sanitäres Einbaureservoir" ist im Folgenden allgemein ein sanitärer Gegenstand bezeichnet, der einerseits unter Putz - und somit fest und schwer zugänglich - montiert wird, und in dem sich andererseits unter den gewöhnlichen Betriebsbedingungen ein Flüssigkeitsvolumen ansammelt. Beispiele für ein solches Einbaureservoir sind insbesondere ein Unterputzsiphon, ferner aber auch ein Unterputzspülkasten für eine Toilettenspülung oder dergleichen.The term "sanitary built-in reservoir" in the following generally refers to a sanitary object which is mounted on the one hand under plaster - and thus firm and difficult to access - and in which, on the other hand, accumulates under the normal operating conditions, a liquid volume. Examples of such a built-in reservoir are, in particular, a flush-mounted siphon, but also a concealed cistern for toilet flushing or the like.

Ein Einbaureservoir der oben genannten Art, insbesondere ein Unterputzsiphon, ist normalerweise mit einer Revisionsöffnung ausgestattet, die dazu dient, das Einbaureservoir zu reinigen oder erforderlichenfalls zu reparieren. Um die Revisionsöffnung flüssigkeitsdicht verschließen zu können, hat die Revisionsöffnung meistens einen Gewindekragen, auf den ein Schraubdeckel aufschraubbar ist. Im Einbauzustand ist die Revisionsöffnung üblicherweise (nur) durch eine Zugangsöffnung in einer dem Reservoir vorgeblendeten Vorbauwand zugänglich. Im Endmontagezustand des Reservoirs sind die Revisionsöffnung und die zugehörige Zugangsöffnung in der Vorbauwand in der Regel durch ein Verkleidungselement verdeckt.A built-in reservoir of the above type, in particular a flush-mounted siphon, is normally equipped with an inspection opening which serves to clean or, if necessary, repair the built-in reservoir. In order to seal the inspection opening liquid-tight, the inspection opening usually has a threaded collar on which a screw cap can be screwed. In the installed state, the inspection opening is usually (only) accessible through an access opening in a reservoir wall vorgeblendeten stem wall. In the final assembly state of the reservoir, the inspection opening and the associated access opening in the stem wall are usually covered by a cladding element.

Die Revisionsöffnung ist üblicherweise derart angebracht, dass sie oberhalb des normalen Flüssigkeitspegels im Inneren des Reservoirs angeordnet ist. Im Fehlerfall, z.B. bei Verstopfung eines Unterputzsiphons, kann es aber vorkommen, dass der Flüssigkeitspegel im Inneren des Reservoirs über den Rand der Revisionsöffnung hinaus ansteigt. In diesem Fall fließt beim Öffnen der Revisionsöffnung ein - oft nicht unerhebliches - Flüssigkeitsvolumen aus dem Reservoir, falls keine geeigneten Sicherheitsvorkehrungen getroffen werden. Oft ergießt sich diese Flüssigkeit zumindest zum Teil in einen hinter der Vorbauwand gebildeten Zwischenraum, wo diese Flüssigkeit nur schwer austrocknen und daher Schimmelbildung hervorrufen kann. Im Falle eines Unterputzsiphons kommt erschwerend hinzu, dass es sich bei der ausströmenden Flüssigkeit um Schmutzwasser handelt, das in besonderem Maße zu Verschmutzungen der Vorbauwand und/oder einer Geruchsbelästigung führen kann.The inspection opening is usually mounted so that it is located above the normal liquid level in the interior of the reservoir. In the event of a fault, for example in the case of blockage of a flush-mounted siphon, it may happen that the liquid level in the interior of the reservoir rises beyond the edge of the inspection opening. In this case flows when opening the inspection opening a - often not insignificant - liquid volume from the reservoir, if no suitable Safety precautions are taken. Often, this liquid pours at least in part into a space formed behind the stem wall, where this liquid is difficult to dry out and therefore can cause mold growth. In the case of a flush-mounted siphon, it is aggravated that the outflowing liquid is wastewater, which can lead to particular contamination of the stem wall and / or odor nuisance.

Zu einem solchen Wasserschaden kommt es mit erhöhter Wahrscheinlichkeit insbesondere dann, wenn die Revisionsöffnung nicht von einer Sanitärfachkraft geöffnet wird, sondern, z.B. testweise, von einem unbedarften Heimwerker.Such a water damage is more likely to occur, in particular if the inspection opening is not opened by a sanitary specialist, but, e.g. For a test, from a low-skilled handyman.

Der Erfindung liegt die Aufgabe zugrunde, eine geeignete Maßnahme zur Vermeidung des vorstehend beschriebenen Problems anzugeben. Insbesondere ist es Aufgabe der Erfindung, eine sanitäre Unterputzeinrichtung mit einem Einbaureservoir dahingehend auszurüsten, dass das vorstehend beschriebene Problem vermieden ist.The invention has for its object to provide a suitable measure to avoid the problem described above. In particular, it is an object of the invention to provide a sanitary flushing device with a built-in reservoir to the effect that the problem described above is avoided.

Bezüglich der Sicherungsvorrichtung wird die Aufgabe erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. Bezüglich der sanitären Unterputzeinrichtung wird die Aufgabe erfindungsgemäß gelöst durch die Merkmale des Anspruchs 12, sowie unabhängig hiervon durch die Merkmale des Anspruchs 13. Die obige Aufgabe wird schließlich auch erfindungsgemäß gelöst durch die Verwendung nach Anspruch 14.With regard to the securing device, the object is achieved by the features of claim 1. With respect to the sanitary Unterputzeinrichtung the object is achieved by the features of claim 12, and independently thereof by the features of claim 13. The above object is finally achieved by the invention the use according to claim 14.

Nach Anspruch 1 ist als Sicherungsvorrichtung für die Revisionsöffnung des sanitären Einbaureservoirs eine Ablaufrutsche vorgesehen, die einerseits einen - insbesondere flachen - Aufhängeabschnitt umfasst, in welchen zur Aufhängung der Ablaufrutsche ein Loch eingebracht ist. Andererseits umfasst die Ablaufrutsche einen - ebenfalls vorzugsweise flachen - Ablaufabschnitt, welcher gegenüber dem Aufhängeabschnitt abgewinkelt oder abwinkelbar ist.According to claim 1, a discharge chute is provided as a securing device for the inspection opening of the sanitary installation reservoir, on the one hand comprises a - in particular flat - suspension section, in which a hole is introduced for the suspension of the chute. On the other hand, the discharge chute comprises a - also preferably flat - discharge section, which is angled or angled relative to the suspension section.

Bestimmungsgemäß wird die Ablaufrutsche mit dem Loch des Aufhängeabschnitts an einem Gewindekragen der zugeordneten Revisionsöffnung aufgehängt, wobei der flache Aufhängeabschnitt im Wesentlichen flach an einer die Revisionsöffnung umgebenden Wand des Einbaureservoirs anliegt. Die Ablaufrutsche wird dabei bestimmungsgemäß derart an der Revisionsöffnung aufgehängt, dass sich der Ablaufabschnitt unterhalb der Revisionsöffnung befindet.According to the invention, the discharge chute with the hole of the suspension section is suspended from a threaded collar of the associated inspection opening, the flat suspension section abutting substantially flat against a wall of the installation reservoir surrounding the inspection opening. The chute will be suspended as intended at the inspection opening, that the drain section is located below the inspection opening.

Grundsätzlich ist im Rahmen der Erfindung denkbar, dass es sich bei der Ablaufrutsche um ein starres Teil handelt, bei dem der Ablaufabschnitt um einen festen stumpfen Winkel von dem Aufhängeabschnitt abgewinkelt ist.In principle, it is conceivable within the scope of the invention that the discharge chute is a rigid part, in which the discharge section is angled away from the suspension section by a fixed obtuse angle.

In einer bevorzugten Variante der Erfindung ist der Ablaufabschnitt aber flexibel gegenüber dem Aufhängeabschnitt abwinkelbar. Der Ablaufabschnitt kann in diesem Fall in der bestimmungsgemäßen Montageposition des Einbaureservoirs hochgeklappt und so hinter der Vorbauwand und dem die Zugangsöffnung verblendenden Verkleidungselement versteckt werden. Mit anderen Worten muss die Ablaufrutsche beim Verschließen der Zugangsöffnung nicht abgenommen werden, sondern kann immer an dem Einbaureservoir verbleiben. Somit ist sichergestellt, dass die Ablaufrutsche nicht verlorengeht, sondern immer sofort zur Hand ist, wenn die Revisionsöffnung geöffnet werden muss. Vor dem Öffnen der Revisionsöffnung kann der flexibel abwinkelbare Ablaufabschnitt dann in eine unter einem stumpfen Winkel von dem Aufhängeabschnitt abstehende Lage verschwenkt werden.In a preferred variant of the invention, however, the drainage section can be bent away from the suspension section in a flexible manner. In this case, the drainage section can be folded up in the intended installation position of the built-in reservoir and thus hidden behind the stem wall and the cladding element facing the access opening. In other words, the drain chute does not have to be removed when closing the access opening, but can always remain on the built-in reservoir. This ensures that the chute is not lost, but is always at hand when the inspection opening needs to be opened. Before opening the inspection opening, the flexibly bendable drainage section can then be pivoted into a position projecting at an obtuse angle from the suspension section.

Bei beiden Varianten der Erfindung ragt der Ablaufabschnitt der Ablaufrutsche - in seinem von dem Aufhängeabschnitt abgewinkelten Zustand - durch die Zugangsöffnung hindurch. Tritt beim Öffnen der Revisionsöffnung Flüssigkeit aus dem Einbaureservoir aus, so fließt diese automatisch über den Ablaufabschnitt durch die Zugangsöffnung hindurch in den Rauminnenbereich ab, wo diese Flüssigkeit leicht aufgefangen und beseitigt werden kann.In both variants of the invention, the discharge section of the discharge chute, in its angled-away state from the suspension section, projects through the access opening. Occurs when opening the inspection opening liquid from the built-in reservoir, it flows automatically through the drain section through the access opening into the interior space, where this liquid can be easily collected and removed.

Die beschriebene Ablaufrutsche ist sehr einfach und intuitiv zu verwenden, so dass es insbesondere auch ungeübten Heimwerkern möglich ist, die RevisionsÖffnung zu öffnen, ohne dass durch ein austretendes Flüssigkeitsvolumen ein signifikanter Schaden angerichtet wird.The described slide is very easy and intuitive to use, so that it is possible in particular even inexperienced home improvement, the RevisionsÖffnung open, without significant damage is caused by an escaping liquid volume.

In einer herstellungstechnisch besonders günstigen Ausführungsform sind sowohl der Aufhängeabschnitt als auch der Ablaufabschnitt aus einer flexiblen, aber eingeschränkt formstabilen Kunststofffolie, in einer zweckmäßigen Ausgestaltung z.B. aus Polyethylen niedriger Dichte (PE-LD oder PE-LLD) mit einer Wandstärke zwischen 0,5mm und 2,0 mm, bevorzugt etwa 0,75mm gefertigt. Die Ablaufrutsche kann abweichend hiervon aber auch als Kunststoffformteil hergestellt sein. Die Ablaufrutsche kann ferner auch aus einem andereren Kunststoff oder Elastomer hergestellt sein.In a manufacturing technology particularly favorable embodiment, both the suspension portion and the drain portion of a flexible, but limited dimensionally stable plastic film, in an expedient embodiment, e.g. made of low density polyethylene (PE-LD or LLDPE) with a wall thickness between 0.5 mm and 2.0 mm, preferably about 0.75 mm. The drainage chute can deviate from this but also be made as a plastic molding. The drain chute can also be made of a different plastic or elastomer.

Zweckmäßigerweise sind der Aufhängeabschnitt und der Ablaufabschnitt einstückig über mindestens ein, vorzugsweise zwei parallele, Filmscharniere miteinander verbunden. Dieser Ausführungsform liegt die Erkenntnis zugrunde, dass ein Filmscharnier ohne das Risiko einer Überbelastung das Anlegen des Ablaufabschnitts an den Aufhängeabschnitt nur bis zu einem gewissen Grad erlaubt. Die Verwendung von zwei parallelen Filmscharnieren ermöglicht hierbei vorteilhafterweise den Ablaufabschnitt gegenüber dem Aufhängeabschnitt um etwa 180° abzuwinkeln. Hierdurch kann der Ablaufabschnitt vor die Revisionsöffnung geklappt werden, so dass die Ablaufrutsche platzsparend verstaubar ist.Conveniently, the suspension portion and the drainage portion are integrally connected to one another via at least one, preferably two parallel, film hinges. This embodiment is based on the finding that a film hinge without the risk of overloading allows the application of the drain section to the suspension section only to a certain extent. The use of two parallel film hinges in this case advantageously allows the discharge section to be bent away from the suspension section by approximately 180 °. In this way, the drain section can be folded in front of the inspection opening, so that the drain slide is stowed to save space.

In einer vorteilhaften Ausführungsform ist die Ablaufrutsche zumindest im Bereich des Ablaufabschnitts - in Blickrichtung auf dessen bestimmungsgemäße Oberseite - zu einer konkaven Form, vorzugsweise zu einer rinnenartigen Form, vorgeformt. Zusätzlich oder alternativ sind jeweils im Bereich der gegenüberliegenden Seitenränder des Aufhängeabschnitts und/oder des Ablaufabschnitts Längsstege gebildet, die von einer Oberseite der Ablaufrutsche abstehen. Die Längsstege dienen dazu, einen Flüssigkeitsstrom nach Art von Seitenwänden zu kanalisieren.In an advantageous embodiment, the chute is at least in the region of the drain section - in the direction of its intended top side - to a concave shape, preferably to a groove-like shape preformed. Additionally or alternatively, in each case in the region of the opposite side edges of the suspension section and / or the drain section longitudinal webs are formed, which project from an upper side of the discharge chute. The longitudinal webs serve to channel a liquid flow in the manner of side walls.

Um einen möglichst langen Ablaufabschnitt in dem naturgemäß sehr beengten Bauraum innerhalb der verschlossenen Zugangsöffnung unterbringen zu können, ist in einer weiteren Ausführungsform vorgesehen, dass der Ablaufabschnitt zwei zueinander parallele Folienlagen umfasst. Dabei ist die erste, obere Folienlage fest mit dem Aufhängeabschnitt verbunden, während die zweite, untere Folienlage gegenüber der oberen Folienlage längsverschiebbar an dieser befestigt ist. Bestimmungsgemäß wird die längsverschiebbare Folienlage bei der Verwendung der Ablaufrutsche gegenüber der oberen Folienlage teleskopartig herausgezogen, so dass eine vergleichsweise große Strecke mit der Ablaufrutsche überbrückt wird.In order to be able to accommodate the longest possible drainage section in the naturally very tight installation space within the closed access opening, it is provided in a further embodiment that the drainage section two comprises mutually parallel foil layers. In this case, the first, upper film layer is firmly connected to the suspension portion, while the second, lower film layer is longitudinally displaceable relative to the upper film layer attached thereto. According to the invention, the longitudinally displaceable film layer is telescopically pulled out in the use of the discharge chute relative to the upper film layer, so that a comparatively large distance is bridged with the discharge chute.

In einer bevorzugten Ausführungsform ist die teleskopierbare Befestigung der Folienlagen aneinander dadurch realisiert, dass die eine der Folienlagen die andere Folienlage jeweils an den seitlichen Rändern formschlüssig umklammert. Vorzugsweise umklammert dabei die untere Folienlage die obere Folienlage, da die zur Umklammerung notwendigerweise zur Oberseite hin umgebogenen Seitenränder gleichzeitig als eine Begrenzung für den eventuell austretenden Flüssigkeitsstrom dienen.In a preferred embodiment, the telescoping attachment of the film layers to each other is realized in that the one of the film layers the form-fitting clasps the other film layer respectively at the lateral edges. Preferably, the lower foil layer clasps the upper foil layer, since the side edges, which are necessarily bent over to the upper side for clamping, at the same time serve as a limitation for the liquid flow that might escape.

Zweckmäßigerweise ist die obere Folienlage im Bereich ihres unteren Rands beziehungsweise die untere Folienlage im Bereich ihres oberen Rands jeweils mit einem zur anderen Folienlage hin abstehenden Quersteg versehen. Diese beiden Querstege wirken zusammen als Anschlag, der verhindert, dass die untere Folienlage gänzlich von der oberen Folienlage abgezogen wird.Expediently, the upper film layer is provided in the region of its lower edge or the lower film layer in the region of its upper edge in each case with a transverse web projecting toward the other film layer. These two transverse webs act together as a stop, which prevents the lower film layer is completely removed from the upper film layer.

Um auch einem Laien deutlich vor Augen zu führen, dass die Ablaufrutsche im Ablaufabschnitt teleskopierbar ist, sind die beiden Folienlagen vorzugsweise verschiedenfarbig ausgebildet. Bevorzugt ist dabei die obere Folienlage aus einem transparenten Kunststoff gebildet, während die untere Folienlage aus einem undurchsichtigen, farbigen Kunststoff gebildet ist.In order to clearly show even to a layman that the discharge chute can be telescoped in the discharge section, the two foil layers are preferably formed in different colors. In this case, the upper film layer is preferably formed from a transparent plastic, while the lower film layer is formed from an opaque, colored plastic.

In einer alternativen Ausführungsform ist vorgesehen, dass die mindestens zwei Folienlagen des Ablaufabschnitts nicht teleskopierbar, sondern miteinander, insbesondere wiederum einstückig durch mindestens ein Filmscharnier, gelenkig verbunden sind. Vorteilhafterweise wird dadurch ermöglicht, den Ablaufabschnitt mehrfach zu falten, wodurch wiederum vergleichsweise wenig Stauraum benötigt wird.In an alternative embodiment, it is provided that the at least two foil layers of the drainage section are not telescopically but are hinged together, in particular in one piece by at least one film hinge. Advantageously, this makes it possible to fold the discharge section several times, which in turn requires comparatively little storage space.

Grundsätzlich ist es dabei auch denkbar, dass der Ablaufabschnitt durch zwei oder mehr gelenkig verbundene Folienlagen, sowie zusätzlich eine oder mehrere längsverschiebbare Folienlagen gebildet ist.In principle, it is also conceivable that the drain section is formed by two or more hingedly connected film layers, as well as additionally one or more longitudinally displaceable film layers.

In einer zweckmäßigen Ausführungsform ist am unteren Ende des Ablaufabschnitts, also jeweils am unteren Rand der letzten Folienlage, ein Quersteg angeformt, der von der Unterseite der Ablaufrutsche absteht. Dieser Quersteg dient als Abtropfkante für Flüssigkeit, die durch Grenzflächenspannungen um die Unterkante der Ablaufrutsche herum geleitet wird.In an expedient embodiment, at the lower end of the drainage section, ie in each case at the lower edge of the last foil layer, a transverse web is formed, which protrudes from the underside of the drainage chute. This crosspiece serves as a drip edge for liquid which is conducted around the lower edge of the chute by interfacial tensions.

In den Aufhängeabschnitt ist vorzugsweise eine Ausnehmung eingebracht, mit der die Ablaufrutsche in bestimmungsgemäßer Einbausituation einen Vorsprung des Einbaureservoirs unter Gewährung eines geringfügigen Spiels zumindest teilweise umklammert. Hierdurch wird eine gewisse, jedoch begrenzte, Verdrehbarkeit der Ablaufrutsche gegenüber dem Einbaureservoir ermöglicht.In the suspension section, a recess is preferably introduced, with which the discharge chute in the intended installation situation at least partially clasps a projection of the built-in reservoir while granting a slight play. As a result, a certain, but limited, rotatability of the chute relative to the built-in reservoir allows.

Im Falle eines Unterputzsiphons ist ein solcher Vorsprung insbesondere durch den Anschlussstutzen des Unterputzsiphons gegeben. Die Ausnehmung ist in diesem Fall vorzugsweise als Einbuchtung in den oberen Rand des Aufhängeabschnitts eingebracht. Zweckmäßigerweise greift der Aufhängeabschnitt zur Bildung von die Schwenkbarkeit begrenzenden Anschlägen mit dem Rand der Ausnehmung um den Anschlussstutzen herum.In the case of a flush-mounted siphon, such a projection is given in particular by the connecting piece of the flush-mounted siphon. The recess is preferably introduced in this case as a recess in the upper edge of the suspension section. Conveniently, the suspension portion engages around the spigot to form pivotable stops with the edge of the recess.

Nach Anspruch 12 umfasst die sanitäre Unterputzeinrichtung ein sanitäres Einbaureservoir, sowie eine Ablaufrutsche gemäß einer der oben genannten Ausführungsformen. Dabei ist die Ablaufrutsche - insbesondere im Sinne einer rationalen Herstellung - vorzugsweise als von dem Einbaureservoir separater Gegenstand gefertigt, welcher reversibel mit dem Aufhängeabschnitt an der Revisionsöffnung befestigt ist.According to claim 12, the sanitary flushing device comprises a sanitary built-in reservoir, and a drainage slide according to one of the above-mentioned embodiments. In this case, the discharge chute-in particular in the sense of a rational production-is preferably made as a separate object from the built-in reservoir, which object is fastened reversibly to the suspension section on the inspection opening.

In einer alternativen Ausführungsform der sanitären Unterputzeinrichtung nach Anspruch 13 ist die Ablaufrutsche, oder zumindest deren Ablaufabschnitt fest, insbesondere einstückig, mit dem Einbaureservoir verbunden. Vorzugsweise ist dabei ein erster Teil, insbesondere eine obere, schmale Folienlage des Ablaufabschnittes starr mit dem Einbaureservoir verbunden, an welche, wiederum vorzugsweise einstückig, eine weitere Folienlage gelenkig anschließt. Der Aufhängeabschnitt kann in dieser Ausführungsform auch entfallen.In an alternative embodiment of the sanitary sub-plastering device according to claim 13, the discharge chute, or at least its discharge section, is fixed, in particular in one piece, connected to the built-in reservoir. Preferably, a first part, in particular an upper, narrow film layer of the discharge section is rigidly connected to the built-in reservoir, to which, in turn, preferably in one piece, another film layer is connected in an articulated manner. The suspension section can also be omitted in this embodiment.

Zur weitestmöglichen Vermeidung einer Verschmutzung der Vorbauwand hat bei allen vorstehend beschriebenen Ausführungsformen der Ablaufrutsche der Ablaufabschnitt - falls möglich in vollständig ausgezogenem oder ausgeklapptem Zustand - vorzugsweise eine Länge von mindestens 4cm, bevorzugt zwischen 5 und 10cm, insbesondere etwa 8cm, damit die gegebenenfalls über diesen Abschnitt ablaufende Flüssigkeit in hinreichendem Abstand zu der Vorbauwand von der Ablaufrutsche abtropft oder abläuft.To avoid contamination of the stem wall in all embodiments described above, the drain chute of the drain section - if possible in fully extended or unfolded state - preferably has a length of at least 4cm, preferably between 5 and 10cm, in particular about 8cm, so that optionally over this section draining liquid drips or runs off the drain chute at a sufficient distance from the stem wall.

Fig. 1 zeigt eine sanitäre Unterputzeinrichtung 1 in einer schematisch angedeuteten bestimmungsgemäßen Einbausituation. Die sanitäre Unterputzeinrichtung 1 umfasst ein sanitäres Einbaureservoir, hier als Unterputzsiphon 2 ausgebildet, eine Ablaufrutsche 3, sowie ein Verkleidungselement 4. Fig. 1 shows a sanitary sub-plasters 1 in a schematically indicated intended installation situation. The sanitary sub-luting device 1 comprises a sanitary built-in reservoir, here designed as a flush-mounted siphon 2, a discharge chute 3, as well as a cladding element 4.

Die hier dargestellte Unterputzeinrichtung 1 dient als Abwasseranschluss für eine grundsätzlich beliebige wasserabführende Einrichtung, z.B. für einen Waschtisch oder eine Waschmaschine (nicht dargestellt), welche mit Hilfe eines Abflussrohrs 5 angeschlossen ist. In der Einbausituation ist der Unterputzsiphon 2 in an sich üblicher Weise hinter einer Vorbauwand 6 (in der Darstellung links) montiert, während das Verkleidungselement 4 vor der Vorbauwand 6 (in der Darstellung rechts), und somit im Inneren eines Sanitärraumes angeordnet ist. Als Sanitärraum ist hierbei allgemein ein beliebiger Gebäuderaum bezeichnet, der mit einem Wasseranschluss versehen ist.The sub-brushing device 1 shown here serves as a wastewater connection for basically any water-removing device, e.g. for a washstand or a washing machine (not shown), which is connected by means of a drain pipe 5. In the installation situation, the flush-mounted siphon 2 is mounted in a conventional manner behind a stem wall 6 (left in the illustration), while the cladding element 4 is arranged in front of the stem wall 6 (in the illustration on the right), and thus inside a sanitary room. As a sanitary room this is generally referred to any building space, which is provided with a water connection.

Der aus PE (Polyethylen) gefertigte Unterputzsiphon 2 umfasst im Wesentlichen ein Siphongehäuse 7, zulaufseitig einen Anschlussstutzen 8, sowie ablaufseitig ein Ablaufrohr 9. Im Siphongehäuse 7 ist ein hier nicht weiter erläuterter Innenaufbau aufgenommen, welcher bewirkt, dass sich zumindest im Betrieb des Unterputzsiphons 2 ein als Geruchsverschluss wirkendes Flüssigkeitsvolumen im Siphongehäuse 7 ansammelt.The flush-mounted siphon 2, which is made of PE (polyethylene), essentially comprises a siphon housing 7, a connection pipe 8 on the inlet side, and a drain pipe 9 on the outlet side. In the siphon housing 7, an internal structure, which is not further explained, is accommodated, which causes at least the operation of the flush-mounted siphon 2 a liquid volume acting as an odor trap accumulates in the siphon housing 7.

Das Ablaufrohr 9 ist an einer Unterseite 10 des Siphongehäuses 7 angeformt. Der Anschlussstutzen 8 ist an einer der Vorwand 6 zugewandten Frontseite 11 an das Siphongehäuse 7 angeformt. Der Anschlussstutzen 8 nimmt das Abflussrohr 5 unter Bildung einer dichtenden Verbindung auf.The drain pipe 9 is formed on an underside 10 of the siphon housing 7. The connecting piece 8 is formed on one of the front wall 6 facing front side 11 to the siphon housing 7. The connecting piece 8 receives the drain pipe 5 to form a sealing connection.

Die Begriffe "Unter-" und "Frontseite" sowie die korrespondierenden Begriffe "unten" und "vorne", sowie die sich hieraus ergebenden entgegengesetzten Begriffe "oben" und "hinten" beziehen sich auf die bestimmungsgemäße Orientierung des Unterputzsiphons 2 und werden im Folgenden unabhängig von dessen tatsächlicher Stellung im umgebenden Raum verwendet. Insbesondere werden diese Begriffe ebenso für alle bestimmungsgemäß an dem Unterputzsiphon 2 angebrachten oder anzubringenden Bauteile herangezogen.The terms "bottom" and "front" and the corresponding terms "bottom" and "front", as well as the resulting opposite terms "top" and "back" refer to the intended orientation of the flush-mounted siphon 2 and are independent in the following used by its actual position in the surrounding space. In particular, these terms also used for all intended as attached to the flush-mounted siphon 2 or components to be mounted.

Unterhalb des Anschlussstutzens 8 ist zu Reparatur- und/oder Reinigungszwecken eine mit einer Schraubkappe verschließbare Revisionsöffnung 12 in das Siphongehäuse 7 eingebracht. Um die Revisionsöffnung 12 zugänglich zu machen, ist in die Vorbauwand 6 eine Zugangsöffnung 13 eingebracht. Diese Zugangsöffnung 13 ist durch das Verkleidungselement 4 verdeckt, indem das Verkleidungselement 4 mit einer zugehörigen Aufsatzmuffe 14 auf den Anschlussstutzen 8 aufgesteckt ist.Below the connecting piece 8, a repair opening 12 closable with a screw cap is inserted into the siphon housing 7 for repair and / or cleaning purposes. In order to make the inspection opening 12 accessible, an access opening 13 is made in the stem wall 6. This access opening 13 is covered by the cladding element 4 by the cladding element 4 is fitted with an associated attachment sleeve 14 on the connecting piece 8.

Um die Revisionsöffnung 12 zu öffnen, wird zunächst das Verkleidungselement 4, wie der in Fig. 2 dargestellten Anwendungssituation zu entnehmen ist, entfernt. Um zu vermeiden, dass beim Öffnen der Revisionsöffnung 12 Flüssigkeit aus dem Siphongehäuse 7 hinter die Vorbauwand 6 läuft, ist die Ablaufrutsche 3 vorgesehen.In order to open the inspection opening 12, first the cladding element 4, as in Fig. 2 shown application situation is removed. In order to avoid that when opening the inspection opening 12 liquid from the siphon housing 7 runs behind the stem wall 6, the discharge chute 3 is provided.

Diese umfasst einerseits einen Aufhängeabschnitt 20 zur Befestigung der Ablaufrutsche 3 an einem Gewindekragen 21 der Revisionsöffnung 12, sowie andererseits einen Ablaufabschnitt 22 zur Ableitung der austretenden Flüssigkeit. Der Ablaufabschnitt 22 ragt durch die geöffnete Zugangsöffnung 13 heraus, so dass die durch die Ablaufrutsche 3 abgeleitete Flüssigkeit beispielsweise in einem Gefäß aufgefangen werden kann.This comprises, on the one hand, a suspension section 20 for fastening the discharge chute 3 to a threaded collar 21 of the inspection opening 12, and, on the other hand, a discharge section 22 for discharging the exiting liquid. The drainage section 22 protrudes through the opened access opening 13 so that the liquid discharged through the drainage chute 3 can be collected, for example, in a vessel.

Die Ablaufrutsche 3 ist hier im Wesentlichen einstückig durch eine flexible Kunststofffolie aus PE-LD (Polyethylen niedriger Dichte) gebildet. In den in etwa quadratischen Aufhängeabschnitt 20 ist etwa mittig ein Loch 23 eingebracht. Dessen Durchmesser d (Fig. 3) ist unwesentlich größer als der Durchmesser D des Gewindekragens 21 dimensioniert, so dass die Ablaufrutsche 3 unter Bildung eines gewissen axialen Formschlusses unverlierbar auf den Gewindekragen 12 aufsteckbar ist. An einem oberen Rand 24 des Aufhängeabschnitts 22 ist eine im Wesentlichen kreissegmentförmige Ausnehmung 25 eingebracht, deren Rand komplementär zur Kontur des Anschlussstutzens 8, sowie eines unten an dem Anschlussstutzen 8 angeformten Axialstegs 26 ist. Die Ausnehmung 25 umschließt sowohl den Axialsteg 26 als auch einen Teil des Anschlussstutzens 8 mit einem geringen Abstand, so dass sie im Zusammenwirken mit dem Axialsteg 26 und dem Anschlussstutzen 8 eine spielbehaftete Verdrehsicherung für die Ablaufrutsche 3 darstellt. Der Aufhängeabschnitt 20 liegt mit seiner Unterseite 27 an der Frontseite 11 des Unterputzsiphons 2 an.The discharge chute 3 is essentially formed in one piece by a flexible plastic film of PE-LD (low-density polyethylene). In the approximately square Aufhängeabschnitt 20 approximately centrally a hole 23 is introduced. Its diameter d ( Fig. 3 ) is insignificantly larger than the diameter D of the threaded collar 21 dimensioned so that the discharge chute 3 is captive on the threaded collar 12 to form a certain axial positive locking. At an upper edge 24 of the suspension portion 22, a substantially circular segment-shaped recess 25 is introduced, the edge of which is complementary to the contour of the connection piece 8, as well as one at the bottom of the Connecting piece 8 integrally formed Axialstegs 26 is. The recess 25 encloses both the axial web 26 and a part of the connecting piece 8 with a small distance, so that it represents a play-related rotation for the discharge chute 3 in cooperation with the axial web 26 and the connecting piece 8. The suspension portion 20 rests with its underside 27 on the front side 11 of the flush-mounted siphon 2.

Fig. 3 zeigt in isolierter Darstellung eine erste Ausführungsform der Ablaufrutsche 3 mit Blick auf ihre Unterseite 27. An den Aufhängeabschnitt 20 ist an einem zum oberen Rand 24 entgegengesetzten unteren Rand 30 ein erstes Filmscharnier 31 angeformt, welches den Aufhängeabschnitt 20 mit einer ersten Längsseite 32 einer schmalen Folienlage 33 gelenkig verbindet. An seiner zweiten Längsseite 34 ist an die Folienlage 33 ein zweites Filmscharnier 35 angeformt, welches die Folienlage 33 mit dem oberen Rand 36 einer im Wesentlichen quadratischen Folienlage 37 des Ablaufabschnitts 22 gelenkig verbindet. Die Breite B der Folienlage 33 entspricht in etwa der Länge L (Fig. 2) des Gewindekragens 21. Durch die beiden parallelen Filmscharniere 31 bzw. 35 wird ermöglicht, die Ablaufrutsche 3 entweder gemäß Fig. 1 nach oben umzuknicken, so dass diese vorder Revisionsöffnung 12 anliegt, bzw. hinter dem Verkleidungselement 4 verstaubar ist, oder gemäß Fig. 2 den Ablaufabschnitt 22 nach vorne zu knicken, so dass die Ablaufrutsche 3 verwendet werden kann. Fig. 3 shows in isolation a first embodiment of the chute 3 with a view of its underside 27. On the suspension section 20 is formed on a top edge 24 opposite bottom edge 30, a first film hinge 31, which the suspension portion 20 having a first longitudinal side 32 of a narrow film layer 33 articulated connects. On its second longitudinal side 34, a second film hinge 35 is integrally formed on the film layer 33, which connects the film layer 33 with the upper edge 36 of a substantially square film layer 37 of the drain section 22 articulated. The width B of the film layer 33 corresponds approximately to the length L (FIG. Fig. 2 ) of the threaded collar 21. By the two parallel film hinges 31 and 35 is made possible, the discharge chute 3 either according to Fig. 1 to fold over so that it rests against the inspection opening 12, or is stowed behind the lining element 4, or according to Fig. 2 buckling the drainage section 22 forward, so that the drainage slide 3 can be used.

Die gesamte Ablaufrutsche 3 weist eine leichte Krümmung zu ihrer Oberseite 38 hin auf, wodurch entlang der Ablaufrutsche 3 eine Rinne für die abzuleitende Flüssigkeit gebildet wird. Um das Ableiten der Flüssigkeit weiter zu verbessern, sind sowohl an den Aufhängeabschnitt 20, als auch an den Ablaufabschnitt 22 - sowohl an der Folienlage 33, als auch an der Folienlage 37 - jeweils zwei Längsstege 40 an jedem Seitenrand 41 angeformt, die jeweils von der Oberseite 38 abstehen. Die Längsstege 40 an der Folienlage 37 sind zum Seitenrand 41 etwas beabstandet, und daher in der Darstellung nicht zu sehen. Jeder Längssteg 40 ist jeweils beidendseitig abgeschrägt, um das Umknicken der Ablaufrutsche 3 zu ermöglichen.The entire discharge chute 3 has a slight curvature towards its upper side 38, whereby a channel for the liquid to be discharged is formed along the discharge chute 3. In order to further improve the discharge of the liquid, two longitudinal webs 40 are integrally formed on each side edge 41, both of the suspension section 20, as well as the drain section 22 - both on the film layer 33, and on the film layer 37 Stand upside 38. The longitudinal webs 40 on the film layer 37 are slightly spaced from the side edge 41, and therefore can not be seen in the illustration. Each longitudinal web 40 is chamfered at both ends, to allow the buckling of the chute 3.

An der Unterseite 27 der Ablaufrutsche 3 ist in der Nähe ihres unteren Randes 42 etwa parallel zu diesem ein Quersteg 43 angeformt. Dieser Quersteg 43 dient dazu, Flüssigkeit, die aufgrund von Grenzflächenspannungen um den Rand 42 herumgeleitet wird, zum Abtropfen zu zwingen.At the bottom 27 of the chute 3, a transverse web 43 is formed approximately parallel to this in the vicinity of its lower edge 42. This crosspiece 43 serves to force liquid, which is led around the edge 42 due to interfacial tensions, to drip off.

Fig. 4 zeigt die Ablaufrutsche 3 in Blickrichtung auf ihre Oberseite 38 in einer zweiten Ausführungsform. Die zweite Ausführungsform entspricht im Wesentlichen der ersten Ausführungsform, jedoch umfasst der Ablaufabschnitt 22 zusätzlich zu der Folienlage 37 eine weitere, untere, zu dieser im Wesentlichen parallele Folienlage 50. Die Folienlage 50 ist in etwa so groß wie die Folienlage 37. Die obere Folienlage 37 ist wie in der ersten Ausführungsform über die beiden Filmscharniere 31 bzw. 35 einstückig und gelenkig mit dem Aufhängeabschnitt 20 verbunden. Die untere Folienlage 50 ist längsverschiebbar an der oberen Folienlage 37 befestigt. Hierzu ist die untere Folienlage 50 an ihren beiden Seitenrändern 51 jeweils zur Bildung einer Führungsnut 52 um etwa 180° zur Oberseite 38 hin umgebogen. In den beiden Führungsnuten 52 ist die obere Folienlage 37 an deren beiden Seitenrändern 41 verschiebbar aufgenommen. Ist die Ablaufrutsche 3 gemäß Fig. 1 hinter dem Verkleidungselement 4 verstaut, so ist die untere Folienlage 50 der Ablaufrutsche 3 vor die obere Folienlage 37 geschoben, während sie bei der Verwendung der Ablaufrutsche 3 zur Verlängerung des Ablaufabschnitts 22, wie hier dargestellt, herausgezogen ist. Fig. 4 shows the chute 3 looking in the direction of its top 38 in a second embodiment. The second embodiment essentially corresponds to the first embodiment, however, the drainage section 22 comprises, in addition to the film layer 37, a further, lower, substantially parallel film layer 50. The film layer 50 is approximately as large as the film layer 37. The upper film layer 37 is as in the first embodiment of the two film hinges 31 and 35 integrally and hingedly connected to the suspension portion 20. The lower film layer 50 is longitudinally displaceably attached to the upper film layer 37. For this purpose, the lower film layer 50 is bent at its two side edges 51 each to form a guide groove 52 by about 180 ° to the top 38 out. In the two guide grooves 52, the upper film layer 37 is slidably received at the two side edges 41. Is the chute 3 according to Fig. 1 stowed behind the cladding element 4, the lower film layer 50 of the chute 3 is pushed in front of the upper film layer 37, while in the use of the chute 3 to extend the drain section 22, as shown here, pulled out.

Um auf den ersten Blick kenntlich zu machen, dass die Ablaufrutsche 3 aus zwei Teilen besteht, ist der Aufhängeabschnitt 20, sowie die Folienlagen 33 und 37 aus transparentem Kunststoff gefertigt, während die verschiebbare untere Folienlage 50 aus undurchsichtig eingefärbtem Kunststoff gefertigt ist.To make it clear at first glance that the chute 3 consists of two parts, the suspension portion 20, and the film layers 33 and 37 made of transparent plastic, while the displaceable lower film layer 50 is made of opaque colored plastic.

Damit die untere Folienlage 50 beim Herausziehen nicht ganz von der oberen Folienlage 37 abgezogen wird, ist wie in Fig. 5 dargestellt, an ihrer Oberseite 53 an ihrem oberen Rand 54 ein Quersteg 55 angebracht, der im ausgezogenen Zustand an dem Quersteg 43 der oberen Folienlage 37 anschlägt.So that the lower film layer 50 is not completely removed from the upper film layer 37 when pulling out, as in Fig. 5 shown on its upper side 53 at its upper edge 54, a cross bar 55 is mounted, which abuts in the extended state on the transverse web 43 of the upper film layer 37.

Optional ist analog zur ersten Ausführungsform auch an der unteren Folienlage 50 an ihren unteren Rand 56 ein von ihrer Unterseite 57 abstehender Quersteg angeformt, welcher wiederum als Abtropfkante dient.Optionally, analogously to the first embodiment, a transverse web protruding from its underside 57 is also integrally formed on the lower film layer 50 at its lower edge 56, which in turn serves as a drip edge.

In bevorzugter Ausführung der Ablaufrutsche 3 sind in die Fläche der Folienlage 37 eine Reihe paralleler, in Ablaufrichtung der abzufangenden Flüssigkeit ausgerichtete Sicken 58 eingebracht. Diese Sicken 58, die bevorzugt zur Oberseite der Folienlage 37 abstehen, dienen einerseits zur Versteifung des Ablaufabschnitts 22. Andererseits kanalisieren diese Sicken 58 vorteilhafterweise die ablaufende Flüssigkeit und verhindern somit, dass die ablaufende Flüssigkeit seitlich ausbricht oder beim Ablauf in Schwingungen gerät. Die Sicken 58 können optimal auch bei dem Ausführungsbeispiel der Ablaufrutsche 3 gemäß Fig. 3 vorgesehen sein.In a preferred embodiment of the discharge chute 3, a row of parallel beads 58 aligned in the direction of flow of the liquid to be caught are introduced into the surface of the film layer 37. These beads 58, which preferably protrude to the upper side of the film layer 37, on the one hand serve to stiffen the drainage section 22. On the other hand, these beads 58 advantageously channel the draining liquid and thus prevent the draining liquid from laterally breaking out or becoming vibrating during the drainage. The beads 58 can optimally in the embodiment of the discharge chute 3 according to Fig. 3 be provided.

Die untere Folienlage 50 gemäß Fig. 5 unterscheidet sich von der in Fig. 4 dargestellten Ausführungsform ferner durch zusätzliche, optimale seitliche Längsstege 59, die - wie die Längsstege 40 - als Seitenwände zur noch besseren Kanalisierung der ablaufenden Flüssigkeit dienen.The lower film layer 50 according to Fig. 5 is different from the one in Fig. 4 illustrated embodiment further by additional, optimal lateral longitudinal webs 59, which - like the longitudinal webs 40 - serve as side walls for even better channeling of the effluent liquid.
