Description

Die Erfindung betrifft eine Wasserablaufeinrichtung für einen oben offenen und unten durch einen Boden verschlossenen Schacht, insbesondere einen an einem Gebäude anbringbaren Lichtschacht, mit einem bodenseitig vorgesehenen Ablaufkanal.The invention relates to a water drainage device for a shaft that is open at the top and closed at the bottom by a floor, in particular a light shaft that can be attached to a building, with a drainage channel provided on the floor.

Bei gebräuchlichen Lichtschächten ist zur Bildung einer Wasserablaufeinrichtung häufig lediglich ein bodenseitiges Loch vorgesehen. Hierbei erweist sich jedoch eine zuverlässige Ableitung von in den Schacht gelangendem Wasser als vergleichsweise schwierig.In the case of conventional light wells, often only one hole in the bottom is provided to form a water drainage device. In this case, however, reliable drainage of water entering the shaft proves to be comparatively difficult.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Anordnung eingangs erwähnter Art zu schaffen, die eine zuverlässige Entwässerung eines Schachts gewährleistet.It is therefore the object of the present invention to create an arrangement of the type mentioned at the outset that ensures reliable drainage of a shaft.

Zur Lösung dieser Aufgabe ist ein den Ablaufkanal enthaltendes, in den Boden des Schachts einbaubares Ablaufrohr vorgesehen, das an seinem oberen, eingangsseitigen Ende eine Sitzanordnung für einen lösbar anbringbaren, mit einer Siebanordnung versehenen Deckel aufweist und das im Bereich seiner Innenseite mit einem nach radial innen vorspringenden Anschlag für eine von unten einschiebbare Drainageleitung und an seiner Außenseite mit einer nach radial außen abstehenden, umlaufenden Kriechwassersperre versehen ist.To solve this problem, a drain pipe is provided that contains the drain channel and can be built into the bottom of the shaft, which has a seat arrangement for a detachably attachable cover provided with a sieve arrangement at its upper, input-side end and which in the region of its inside with a radially inward protruding stop for a drainage line that can be inserted from below and is provided on its outside with a radially outwardly projecting, circumferential anti-leakage barrier.

Das erfindungsgemäße Ablaufrohr ermöglicht einen einfach herstellbaren, zuverlässigen Anschluss der von unten einsteckbaren, zu einer Kanalisation etc. führenden Drainageleitung. Der dieser zugeordnete Anschlag stellt sicher, dass die von unten einsteckbare Drainageleitung auch bei einer Blindmontage auf der Baustelle bis auf Anschlag und damit mit der gewünschten Länge zuverlässig zum Eingriff in das Ablaufrohr gebracht werden kann. Die dem abnehmbaren Deckel zugeordnete Siebanordnung stellt sicher, dass zwar Wasser abfließen kann, unerwünschte Verunreinigungen jedoch zurückgehalten werden, so dass einer Rohrverstopfung sowie einer Versandung und/oder Verschlammung einer angeschlossenen Kanalisation oder Sickergrube etc. wirksam vorgebeugt ist. Infolge der Abnehmbarkeit des Deckels ist nicht nur eine einfache Reinigung der Siebanordnung möglich, sondern ergibt sich auch eine gute Zugänglichkeit zur Innenseite des Ablaufrohrs und der hieran anschließenden Drainageleitung für Wartungszwecke etc.. Die von der Außenseite des Ablaufrohrs abstehende Kriechwassersperre, die einfach als umlaufender Flansch ausgebildet sein kann, verhindert in vorteilhafter Weise, dass von unten anstehendes Druckwasser zurückgehalten wird und nicht am Ablaufrohr vorbei in das Schachtinnere gelangen kann.The drain pipe according to the invention enables a simple to manufacture, reliable connection of the drainage line that can be inserted from below and leads to a sewage system. The stop associated with this ensures that the drainage line, which can be inserted from below, can be reliably engaged in with a blind installation on the construction site up to the stop and thus with the desired length the drain pipe can be brought. The sieve arrangement assigned to the removable cover ensures that although water can drain off, unwanted impurities are retained, so that a pipe blockage and silting up and/or silting up in a connected sewage system or septic tank etc. is effectively prevented. As the cover can be removed, not only is the sieve arrangement easy to clean, but there is also good access to the inside of the drain pipe and the drainage line connected to it for maintenance purposes, etc. can be formed, prevents in an advantageous manner that pending pressurized water is retained from below and can not get past the drain pipe into the shaft interior.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous refinements and expedient developments of the higher-level measures are specified in the dependent claims.

So kann zweckmäßig eine mehrstufige Siebanordnung mit einem eingangsseitigen Grobsieb und wenigstens einem diesem nachgeordneten Feinsieb vorgesehen sein. Hierdurch ergibt sich eine hohe Abscheidewirkung, indem nicht nur größere Fremdkörper, wie Laub etc., zurückgehalten werden, sondern auch feinere Verunreinigungen wie Sand etc..A multi-stage screen arrangement with a coarse screen on the inlet side and at least one fine screen arranged downstream of this can be expediently provided. This results in a high separation effect, in that not only larger foreign bodies, such as leaves, etc., are retained, but also finer impurities such as sand, etc..

Eine weitere zweckmäßige Maßnahme kann darin bestehen, dass das Ablaufrohr im Bereich des dem Deckel zugeordneten Sitzes mit einer umlaufenden, einem deckelseitigen Eingriffsstutzen zugeordneten Dichtung und unterhalb hiervon mit einer nach radial innen vorspringenden, vorzugsweise als umlaufende Rippe ausgebildeten Anschlagelement versehen ist, dessen Oberseite als Anschlag für den deckelseitigen Eingriffsstutzen und dessen Unterseite den der Drainageleitung zugeordneten Anschlag bildet. Infolge dieser Doppelwirkung des Anschlagelements kommt man mit einem Anschlagelement aus, was die Herstellung erleichtert.A further expedient measure can be that the drain pipe is provided in the area of the seat assigned to the cover with a circumferential seal assigned to a cover-side engagement socket and below this with a stop element projecting radially inwards, preferably designed as a circumferential rib, the upper side of which acts as a stop forms the stop associated with the drainage line for the access socket on the cover and the underside of which. As a result of this double action of the stop element, one stop element is sufficient, which simplifies production.

Vorteilhaft kann der genannte Deckel drehbar und mittels eines Bajonettverschlusses gegen Abheben gesichert sein. Hierdurch ergibt sich eine einfache Abnehmbarkeit und dennoch ein zuverlässiger Halt des Deckels. Zur Vereinfachung der Manipulation des Deckels kann dieser vorteilhaft mit einem Eingriffselement zum Ansetzen eines geeigneten Werkzeugs versehen sein.Advantageously, said cover can be rotated and secured against being lifted off by means of a bayonet lock. This results in easy detachability and still a reliable hold of the lid. In order to simplify the manipulation of the cover, it can advantageously be provided with an engagement element for attaching a suitable tool.

Gemäß einer weiteren vorteilhaften Ausgestaltung der übergeordneten Maßnahmen kann eine der eingangsseitigen Siebanordnung nachgeordnete Siphonanordnung vorgesehen sein, die zweckmäßig ein trichterförmiges Durchlasselement mit einer oberen Einlassöffnung und einer unteren Auslassöffnung aufweist, welcher eine umlaufende Dichtung und eine durch eine an ihr angreifende Schließkraft in ihrer an der Dichtung anliegenden Schließstellung haltbare und durch eine vom ankommenden Wasser ausgeübte Kraft entgegen der Wirkung der Schließkraft in Öffnungsrichtung bewegbare Verschlussklappe zugeordnet ist. Die Siphonanordnung ergibt in vorteilhafter Weise eine zuverlässige Geruchssperre, so dass aus einer Kanalisation etc. aufsteigende Gerüche zurückgehalten werden. Die durch das ankommende Wasser entgegen einer vorgesehenen Schließkraft betätigbare Verschlussklappe ergibt in vorteilhafter Weise eine automatische Funktionsweise.According to a further advantageous embodiment of the higher-level measures, a siphon arrangement can be provided downstream of the sieve arrangement on the inlet side, which expediently has a funnel-shaped passage element with an upper inlet opening and a lower outlet opening, which has a peripheral seal and a closing force acting on it in its on the seal adjacent closed position is assigned durable and by a force exerted by the incoming water force against the action of the closing force in the opening direction movable closure flap. The siphon arrangement advantageously results in a reliable odor barrier, so that odors rising from a sewage system, etc., are held back. The closing flap, which can be actuated by the incoming water against an intended closing force, advantageously results in an automatic mode of operation.

In weiterer Fortbildung dieser Maßnahmen kann die Siphonanordnung vorteilhaft in den Deckel eingebaut sein. Hierdurch wird sichergestellt, dass die Siphonanordnung für Inspektionszwecke etc. leicht vom Ablaufrohr abnehmbar ist.In a further development of these measures, the siphon arrangement can advantageously be built into the cover. This ensures that the siphon assembly can be easily removed from the drain pipe for inspection etc.

Eine weitere vorteilhafte Maßnahme kann darin bestehen, dass die der Auslassöffnung der Siphonanordnung zugeordnete Verschlussklappe als Wanne ausgebildet ist, die im Bereich ihres Rands um eine horizontale Achse schwenkbar gelagert ist und der eine die Schließkraft erzeugende Einrichtung zugeordnet ist. In der die Verschlussklappe bildenden Wanne kann sich nach und nach so viel Wasser sammeln, dass dessen Gewicht ausreicht, um die Verschlussklappe entgegen der Wirkung der hieran angreifenden Schließkraft zu öffnen. Hierdurch ist auch bei einem geringeren Wasseranfall eine zuverlässige Funktionsweise gewährleistet.
Zur Erzeugung der Schließkraft kann einfach ein mit der Verschlussklappe in Form einer zweiarmigen Wippe zusammenwirkendes Gegengewicht vorgesehen sein. Dies ergibt in vorteilhafter Weise eine teilearme, wartungsfreie Anordnung.
A further advantageous measure can consist in the closure flap associated with the outlet opening of the siphon arrangement being designed as a trough which is pivotably mounted about a horizontal axis in the region of its edge and to which a device generating the closing force is allocated. In the trough forming the closure flap, so much water can gradually collect that its weight is sufficient to open the closure flap against the effect of the closing force acting on it. This ensures reliable functioning even with less water accumulation.
To generate the closing force, a counterweight that interacts with the closing flap in the form of a two-armed rocker can simply be provided. This advantageously results in a low-parts, maintenance-free arrangement.

Eine weitere zweckmäßige Maßnahme kann darin bestehen, dass das Ablaufrohr oder/und der Deckel als aus Kunststoff hergestellte Formlinge, zweckmäßig als Kunststoff-Spritzgussformlinge, ausgebildet sind. Um dabei für verschiedene Schachtbodendicken mit einem Formteil auszukommen, kann einfach vorgesehen sein, dass das Ablaufrohr mit einer einer maximalen Bodendicke entsprechenden Länge hergestellt wird und mit Abstand vom unteren Ende mit wenigstens einer, vorzugsweise mehreren, in der Höhe gegeneinander gestaffelten, verschiedenen gängigen Bodendicken zugeordneten Ablängmarkierungen versehen ist.A further expedient measure can be that the drain pipe and/or the cover are designed as moldings made of plastic, expediently as plastic injection moldings. In order to get by with one molded part for different shaft base thicknesses, it can simply be provided that the discharge pipe is produced with a length corresponding to a maximum base thickness and is assigned at a distance from the lower end with at least one, preferably several, different common base thicknesses staggered in height cutting marks is provided.

In Figur 1 ist ein Lichtschacht etc. nur durch seinen Boden 1 angedeutet, der eine Wasserablaufeinrichtung 2 zum Ableiten von in den Schacht über seine offene Oberseite gelangendem Wasser enthält. Diese besitzt ein in den Boden 1 eingebautes, das heißt hier einbetoniertes, vertikales Ablaufrohr 3, das gemäß Figur 2 einen Ablaufkanal 4 begrenzt.In figure 1 a light well etc. is indicated only by its bottom 1 which contains water drainage means 2 for draining water entering the well via its open top. This has a built into the ground 1, that is concreted here, vertical drain pipe 3, according to figure 2 a discharge channel 4 limited.

Zur Bildung des Ablaufrohrs 3 findet zweckmäßig ein aus Kunststoff bestehender Formkörper, insbesondere ein Kunststoff-Spritzgussformling, Verwendung. Das Ablaufrohr 3 ist gemäß Figur 1 oben und unten bündig mit der Oberseite beziehungsweise Unterseite des Bodens 1 und besitzt dementsprechend im eingebauten Zustand eine der Dicke des Bodens 1 entsprechende Länge. Um für verschiedene Bodenstärken mit einem Formteil auszukommen, besitzt das dem Ablaufrohr 3 zugrundeliegende Formteil im Ausgangszustand eine Länge, welche einer in der Praxis vorkommenden, maximalen Bodendicke entspricht, wobei gemäß Figur 2 mit Abstand vom unteren Ende wenigstens eine, vorzugsweise mehrere, in der Höhe gestaffelt angeordnete, jeweils einer gängigen Bodendicke zugeordnete, in Figur 2 durch unterbrochene Linien angedeutete Ablängmarkierungen 5 vorgesehen sind. Diese können beispielsweise als in den äußeren Umfang eingeformte Rillen etc. ausgebildet sein. Dem Ablaufrohr 3 gemäß Figur 1 liegt beispielsweise ein an der obersten Ablängmarkierung abgeschnittenes Formteil zugrunde.A molded body made of plastic, in particular a plastic injection molding, is expediently used to form the drain pipe 3 . The drain pipe 3 is according to figure 1 flush at the top and bottom with the top and bottom of the floor 1 and accordingly has a length corresponding to the thickness of the floor 1 when installed. In order to manage with one molded part for different bottom thicknesses, the molded part on which the discharge pipe 3 is based has a length in the initial state which corresponds to a maximum bottom thickness occurring in practice, with at least one, preferably several, in height at a distance from the lower end according to Figure 2 staggered, each assigned to a common bottom thickness, in figure 2 cutting marks 5 indicated by broken lines are provided. These can be designed, for example, as grooves etc. formed into the outer circumference. According to the drain pipe 3 figure 1 is based, for example, on a molded part cut off at the uppermost cutting mark.

In das Ablaufrohr 3 ist gemäß Figur 1 von unten der obere Endbereich einer rohrförmigen, zu einer Kanalisation etc. führenden Drainageleitung 6 eingesteckt. Um bei einem an einem Gebäude angebrachten Lichtschacht vor Ort das Einstecken der Drainageleitung 6 in das Ablaufrohr 5 von unten, das heißt eine Blindmontage der Drainageleitung 6 zu erleichtern, ist im Bereich der Innenseite des Ablaufrohrs 3 ein der Drainageleitung 6 zugeordneter, radial nach innen vorspringender Anschlag vorgesehen, der gemäß Figur 2 einfach als umlaufende Innenrippe 7 ausgebildet sein kann. Zur Bildung einer Einführhilfe kann das obere Ende der Drainageleitung 6 zweckmäßig konisch angephast sein, wie in Figur 1 angedeutet ist. Der in das Ablaufrohr 3 eingesteckte Endbereich der Drainageleitung 6 ist, wie Figur 1 weiter zeigt, gegenüber dem Ablaufrohr 3 abgedichtet, um von unten anstehendes Druckwasser abzuhalten. Hierzu ist das Ablaufrohr 3 gemäß Figur 2 in seinem unteren Bereich mit einer inneren, umlaufenden Dichtung 8 versehen, die in eine zugeordnete Innennut des Ablaufrohrs 3 eingelegt ist.In the drain pipe 3 is according figure 1 the upper end region of a tubular drainage line 6 leading to a sewage system etc. is inserted from below. In order to facilitate the on-site insertion of the drainage line 6 into the drain pipe 5 from below, i.e. a blind installation of the drainage line 6, in the case of a light shaft attached to a building, in the area of the inside of the drain pipe 3 there is a radially inwardly projecting part assigned to the drainage line 6 Stop provided according to figure 2 simply as a circumferential inner rib 7 can be trained. To form an insertion aid, the upper end of the drainage line 6 can expediently be chamfered conically, as in figure 1 is indicated. The plugged into the drain pipe 3 end of the drainage line 6 is how figure 1 further shows, sealed against the drain pipe 3 to keep pending pressurized water from below. For this purpose, the drain pipe 3 according to figure 2 provided in its lower area with an inner, circumferential seal 8, which is inserted into an associated inner groove of the drain pipe 3.

Um zu vermeiden, dass von unten anstehendes Druckwasser in Form von Kriechwasser entlang des Außenumfangs des Ablaufrohrs 3 in das Schachtinnere gelangt, ist das Ablaufrohr 3 gemäß Figur 1 mit einer von seinem Außenumfang nach radial außen abstehenden, in den umgebenden Beton hineinragenden, umlaufenden Kriechwassersperre 9 versehen. Zur Bildung der Kriechwassersperre 9 kann der dem Ablaufrohr 3 zugrundeliegende Formling gemäß Figur 2 einfach mit einem umlaufenden Außenflansch versehen sein. Die Flanschbreite, das heißt die Breite der Kriechwassersperre 9, ist dabei so bemessen, dass der hierdurch erzeugte, dem Kriechwasser entgegengesetzte Widerstand ausreicht, um eine Umwanderung durch das Kriechwasser zu verhindern.In order to prevent water under pressure from below in the form of seeping water along the outer circumference of the drain pipe 3 into the interior of the shaft, the drain pipe 3 according to FIG figure 1 provided with a circumferential anti-leakage barrier 9 protruding radially outwards from its outer circumference and protruding into the surrounding concrete. To form the water seepage barrier 9, the molding on which the drain pipe 3 is based can be figure 2 simply be provided with a peripheral outer flange. The flange width, that is to say the width of the seepage water barrier 9, is dimensioned in such a way that the resistance generated thereby and opposed to the seepage water is sufficient to prevent the seepage water from migrating around.

Das Ablaufrohr 3 ist, wie Figur 1 weiter zeigt, an seiner oberen Eingangsseite durch einen Deckel 10 abgeschlossen. Diesem kann ebenfalls ein Kunststoffformling, vorzugsweise ein Kunststoff-Spritzgussformling der in Figur 3 gezeigten Art, zugrunde liegen. Zur Aufnahme des Deckels 10 ist das Ablaufrohr 3 gemäß Figur 2 mit einem dem Deckel 10 zugeordneten Sitz 11 versehen, in welchen der Deckel 10 mit einem nach unten vorstehenden Einsteckstutzen 12 einsteckbar ist. Im Bereich des Sitzes 11 ist zweckmäßig eine dem Einsteckstutzen 12 zugeordnete Dichtung 13 vorgesehen, welche wie die Dichtung 8 in eine zugeordnete Innennut des Ablaufrohrs eingelegt sein kann. Dem unteren Ende des Einsteckstutzens 12 ist ablaufrohrseitig ein die Einsteckbewegung begrenzender Anschlag zugeordnet. Dabei kann es sich um einen eigenen, nach radial innen vorspringenden Anschlag handeln. Im dargestellten Beispiel ist zur Bildung des dem von oben einsteckbaren Deckel 10 zugeordneten Anschlags und des der von unten einsteckbaren Drainageleitung 6 zugeordneten Anschlags eine gemeinsame Anschlaganordnung in Form der bereits erwähnten Rippe 7 vorgesehen, deren Unterseite den der Drainageleitung 6 zugeordneten Anschlag und dessen Oberseite den dem Deckel 10 zugeordneten Anschlag bildet.The drain pipe 3 is how figure 1 further shows closed at its upper input side by a cover 10. This can also be a plastic molding, preferably a plastic injection molding of the figure 3 shown kind, underlying. To accommodate the cover 10, the drain pipe 3 is provided according to FIG. In the area of the seat 11, a seal 13 associated with the insertion socket 12 is expediently provided, which, like the seal 8, can be inserted into an associated inner groove of the drain pipe. A stop limiting the insertion movement is assigned to the lower end of the insertion socket 12 on the drain pipe side. This can be a separate stop projecting radially inward. In the example shown, a common stop is used to form the stop associated with the cover 10 that can be inserted from above and the stop associated with the drainage line 6 that can be inserted from below Stop arrangement is provided in the form of the already mentioned rib 7, the underside of which forms the stop associated with the drainage line 6 and the top of which forms the stop associated with the cover 10.

Der Deckel 10 muss natürlich wasserdurchlässig sein und ist hierzu im dargestellten Beispiel mit einer aus Figur 4 erkennbaren Siebanordnung versehen. Diese ist hier zweistufig ausgebildet und enthält ein eingangsseitiges Grobsieb 14 und ein diesem nachgeordnetes Feinsieb 15. Durch das Grobsieb werden größere Verunreinigungen in Form von Laub etc. und durch das Feinsieb 15 feinere Verunreinigungen, beispielsweise Sand, zurückgehalten. Durch die Dichtung 13 wird eine die Siebanordnung umgehende Bypassströmung verhindert. Zur Reinigung der Siebanordnung ist der Deckel 10 abnehmbar.Of course, the cover 10 must be water-permeable and, in the example shown, it is equipped with a figure 4 recognizable sieve arrangement provided. This is designed here in two stages and contains a coarse screen 14 on the input side and a fine screen 15 arranged downstream of this. A bypass flow bypassing the screen arrangement is prevented by the seal 13 . The cover 10 can be removed for cleaning the screen arrangement.

Der abnehmbare Deckel 10 ist vorteilhaft gegen unbeabsichtiges Abheben gesichert. Hierzu ist der Deckel 10 gemäß Figur 5 mit radial vorspringenden Flanschsegmenten 16 versehen, die gemäß Figur 3 mit Abstand von der Deckeloberseite positioniert sind. Das Ablaufrohr 3 ist, wie Figur 2 erkennen lässt, mit einer den Flanschsegmenten 16 zugeordneten, durch Innenrippen des Ablaufrohrs 3 begrenzten Nut 17 versehen, wobei die die obere Nutzbegrenzung bildende obere Rippe 18 mit der Form der Flanschsegmente 16 entsprechenden, hier nicht näher dargestellten Ausschnitten versehen ist, über welche die Flanschsegmente 16 beim Einstecken des Deckels 10 in den zugeordneten Sitz 11 in die Nut 17 eingeführt werden können. Durch anschließendes Drehen des Deckels 10 wird dieser gegen Abheben gesperrt. Um das Drehen des Deckels 10 zu erleichtern, ist dieser gemäß Figur 3 zweckmäßig mit einem von oben zugänglichen Eingriffselement 19 zum Ansetzen eines geeigneten Drehwerkzeugs, beispielsweise mit einem Schlitz zum Ansetzen eines Schraubenziehers etc., versehen. Hierdurch wird auch das Abheben des Deckels 10 erleichtert. Zur Bildung des Sitzes 11 ist das Ablaufrohr 3 zweckmäßig mit einem oberen Kragen 20 versehen, an den die der Dichtung 13 zugeordnete Nut sowie die diese und die Nut 17 begrenzenden Rippen angeformt sind.The removable cover 10 is advantageously secured against unintentional lifting. For this purpose, the cover 10 according to figure 5 provided with radially projecting flange segments 16 according to figure 3 positioned at a distance from the top of the lid. The drain pipe 3 is how figure 2 can be seen, provided with a groove 17 assigned to the flange segments 16 and delimited by inner ribs of the drain pipe 3, wherein the upper rib 18 forming the upper usable limit is provided with cutouts, not shown here, corresponding to the shape of the flange segments 16, via which the flange segments 16 can be inserted into the groove 17 when inserting the cover 10 into the associated seat 11. By subsequently rotating the cover 10, it is blocked against being lifted off. In order to make it easier to turn the cover 10, according to FIG figure 3 expediently provided with an engaging element 19 accessible from above for attaching a suitable turning tool, for example with a slot for attaching a screwdriver etc. This also makes it easier to lift off the cover 10 . To form the seat 11, the drain pipe 3 is expediently provided with an upper collar 20, on which the groove associated with the seal 13 and the ribs delimiting this and the groove 17 are formed.

Der eingangsseiten Siebanordnung kann zur Bildung einer Geruchssperre eine Siphonanordnung nachgeordnet sein. Diese kann wie die Siebanordnung zweckmäßig ebenfalls dem Deckel 10 zugeordnet sein, wie aus den Figuren 6 und 7 entnehmbar ist. Alternativ zum Einbau der Siphonanordnung in den Deckel 10 wäre aber auch eine Anordnung innerhalb des Ablaufrohrs 3 denkbar. Die Siphonanordnung enthält im dargestellten Beispiel, wie aus den Figuren 6 und 7 erkennbar ist, ein trichterförmiges Durchlassteil 21 mit einer oberen Einlassöffnung und einer unteren Auslassöffnung, der eine Verschlussklappe 22 zugeordnet ist, die unter der Wirkung des von oben kommenden Wassers selbsttätig öffnet und, wenn kein Wasser mehr kommt, unter der Wirkung einer hieran angreifenden Schließkraft selbsttätig schließt. Der Figur 6 liegt der geschlossene Zustand, der Figur 7 der geöffnete Zustand zugrunde. Im Bereich der Auslassöffnung des Durchlassteils 21 ist eine umlaufende Dichtung 23 vorgesehen, an welcher die Verschlussklappe 22 in der der Figur 6 zugrunde liegenden Schließstellung anliegt.The upstream screen assembly may be a siphon assembly to form an odor barrier be subordinate. Like the sieve arrangement, this can also be appropriately associated with the cover 10, as can be seen from FIGS Figures 6 and 7 is removable. As an alternative to installing the siphon arrangement in the cover 10, an arrangement within the drain pipe 3 would also be conceivable. The siphon arrangement contains in the example shown, as from the Figures 6 and 7 can be seen, a funnel-shaped passage part 21 with an upper inlet opening and a lower outlet opening, to which a closure flap 22 is assigned, which opens automatically under the effect of the water coming from above and, when no more water comes in, automatically under the effect of a closing force acting on it closes. the figure 6 lies the closed state, the figure 7 based on the open state. In the area of the outlet opening of the passage part 21, a peripheral seal 23 is provided, on which the closure flap 22 in the figure 6 underlying closed position is present.

Die Verschlussklappe 22 kann als zum Beispiel aus Kunststoff oder Hartgummi etc. bestehende, nach Art einer Blattfeder gestaltete Federzunge ausgebildet sein, die an einem Ende eingespannt ist und durch eine von oben wirkende Kraft entgegen ihrer Federwirkung nach unten ausgelenkt werden kann. Im dargestellten Beispiel ist die Verschlussklappe 22 zur Bildung eines Auffanggefäßes wannen- oder topfförmig ausgebildet. Die so ausgebildete Verschlussklappe 22 ist im Bereich ihres Rands um eine horizontale Achse schwenkbar an einem an das Durchlassteil 21 angesetzten Lagerbock 23 gelagert. Durch das Gewicht des in dem die Verschlussklappe 22 bildenden Gefäß gesammelten Wassers wird die schwenkbar gelagerte Verschlussklappe 22 entgegen einer ihr zugeordneten Schließkraft geöffnet. Zur Erzeugung der Schließkraft kann ein mit der Verschlussklappe 22 zusammenwirkendes Gegengewicht 24 vorgesehen sein, das zusammen mit der Verschlussklappe 22 praktisch eine zweiarmige Wippe bildet, die so austariert ist, dass die Verschlussklappe 22 öffnet, sobald sich im die Verschlussklappe 22 bildenden Auffanggefäß eine gewünschte Wassermenge angesammelt hat. Es wäre aber auch denkbar, zur Erzeugung der Schließkraft eine mit der Verschlussklappe 22 zusammenwirkende Schließfeder vorzusehen, beispielsweise in Form einer in die Schwenklagerung integrierten Torsionsfeder.The closure flap 22 can be designed as a spring tongue, for example made of plastic or hard rubber etc., designed like a leaf spring, which is clamped at one end and can be deflected downwards by a force acting from above against its spring effect. In the example shown, the closure flap 22 is designed in the shape of a trough or pot to form a collecting vessel. The closure flap 22 designed in this way is mounted on a bearing block 23 attached to the passage part 21 so that it can pivot about a horizontal axis in the region of its edge. Due to the weight of the water collected in the vessel forming the closure flap 22, the pivotably mounted closure flap 22 is opened against a closing force assigned to it. To generate the closing force, a counterweight 24 that interacts with the closure flap 22 can be provided, which together with the closure flap 22 practically forms a two-armed seesaw that is balanced in such a way that the closure flap 22 opens as soon as a desired quantity of water is present in the collection vessel forming the closure flap 22 has accumulated. However, it would also be conceivable to provide a closing spring which interacts with the closing flap 22 in order to generate the closing force, for example in the form of a torsion spring integrated into the pivot bearing.

Vorstehend ist zwar ein besonders bevorzugtes Ausführungsbeispiel der Erfindung näher erläutert, ohne dass jedoch hiermit eine Beschränkung verbunden sein soll. So wäre es beispielsweise auch denkbar, die Kriechwassersperre 9 nicht an das Auslaufrohr 3 anzuformen, sondern anzusetzen. Ebenso wäre es denkbar, den Deckel 10 mittels eines Schraubgewindes im Ablaufrohr 3 festzulegen und dergleichen.Although a particularly preferred exemplary embodiment of the invention has been explained in more detail above, this is not intended to be associated with a restriction. It would also be conceivable, for example, not to form the anti-leakage device 9 on the outlet pipe 3, but rather to attach it. It would also be conceivable to fix the cover 10 in the drain pipe 3 by means of a screw thread and the like.
