Abstract

An insertion part (20) which is circular in plan, is sealingly inserted in a pot (10) having a lateral inlet connection (13) and an opposite outlet connection (14). A semicircular shaft (23), which receives water from above or through the lateral connection (13), is formed on the inlet side through the insertion part by a straight baffle (23a) moulded thereon. The water rises in a crescent-shaped shaft (29) opens, by means of its pressure, a backwater flap (28) hinge-mounted on the insertion part, flows over a baffle plate (16) and out through the connection (14). As a result of the backwater flap, a barrier is provided against water flowing back. In addition, it acts as an odour seal when no water level is present. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Ablaufarmatur für Badezimmer mit den Merkmalen nach dem Oberbegriff des Anspruchs 1 (vgl. GB-A-2 094 847).The invention relates to a drain fitting for bathrooms with the features according to the preamble of claim 1 (cf. GB-A-2 094 847).

Ablaufarmaturen dieser Art werden im Boden von Badezimmern eingebaut und dienen zur Aufnahme des bodenseitig anfallenden Wassers und zur Weiterleitung an die gebäudeseitige Abwasserleitung. Zusätzlich ist noch ein seitlicher Einlauf vorgesehen zur Aufnahme des aus der Badewanne abfließenden Wassers. Diese Armaturen sind mit Elementen für Geruchsverschluß vorgesehen. Zu diesen Elementen gehört ein Topf, der mit Wasser gefüllt ist und ein in den Topf eintauchender Schacht. Das von oben einfließende Wasser sinkt in den Schacht ab, steigt außerhalb des Schachtes im Topf hoch, überläuft dort eine Überlaufkante und gelangt von dort in einer seitlichen Ablaufstutzen.Drain fittings of this type are installed in the floor of bathrooms and serve to absorb the water accumulating on the floor and to pass it on to the sewage pipe on the building side. In addition, a side inlet is provided to hold the water flowing out of the bathtub. These fittings are provided with elements for odor trap. These elements include a pot that is filled with water and a shaft that is immersed in the pot. The water flowing in from above sinks into the shaft, rises in the pot outside the shaft, overflows there over an overflow edge and arrives from there in a side outlet connection.

Bekannt ist eine Ablaufarmatur für Badezimmer (GB-A-2 094 847), bei welcher der eintauchende Schacht durch ein Einsatzteil gebildet wird, das in den Topf eingesetzt wird und ringsum dicht abschließt. Der Überlaufbereich im Topf ist durch angeformte, im Grundriß rechteckige Stauwände gebildet, die durch Schrägflächen in den radialen Ablaufstutzen übergehen. Der Überlaufbeieich wird durch einen Teil des Einsatzteils, der wie eine Kappe geformt ist, abgedeckt. Bei dieser bekannten Bodenablaufarmatur ist kein seitlicher Zulaufstutzen für den Zulauf des Wassers aus der Badewanne vorgesehen, ebensowenig wie Vorkehrungen für eine Verhinderung von Rückstauwasser getroffen sind.A drainage fitting for bathrooms is known (GB-A-2 094 847), in which the immersing shaft is formed by an insert part which is inserted into the pot and closes tightly all around. The overflow area in the pot is formed by integrally formed baffle walls which are rectangular in plan and which merge into the radial outlet spout through inclined surfaces. The overflow area is covered by a part of the insert part which is shaped like a cap. In this known floor drain fitting, no lateral inlet connection is provided for the inflow of water from the bath tub, just as little as no precautions are taken to prevent backwater.

Weiterhin bekannt (DE-B-3 044 426) ist ein Bodenablauf für Badezimmer, bei dem an einem Topf, der von oben Wasser aufnehmen kann, auch ein seitlicher Zulaufstutzen für Wasser aus der Badewanne angeformt ist. Auch dieser Topf nimmt ein ringsum abgedichtetes Einsatzteil auf, an dem ein eintauchender Schacht in Form eines rechtwinklig gekrümmten Tauchrohres angeformt ist. Vorkehrungen für eine Verhinderung des Rückstaus sind auch bei diesen bekannten Bodenablauf nicht getroffen.Also known (DE-B-3 044 426) is a floor drain for bathrooms, in which a side inlet connection for water from the bathtub is also formed on a pot that can absorb water from above. This pot also receives an all-round sealed insert, on which an immersing shaft in the form of a right-angled one Dip tube is molded. Precautions for preventing the backflow are not taken even with this known floor drain.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Ablaufarmatur für Badezimmer so auszubilden, daß nicht nur bodenseitiges Wasser von oben, sondern auch zusätzlich Wasser aus der Badewanne aufgenommen werden kann, und daß überdies Vorkehrungen getroffen sind, daß rückfließendes Wasser aus den Abwasserleitungen nicht über die Armatur in den Raum eindringt.The object of the present invention is to design a drain fitting for bathrooms so that not only water from the bottom can be taken up from the top, but also additional water from the bath tub, and that, in addition, precautions are taken that the water flowing back from the sewage pipes does not have the Armature penetrates into the room.

Vorkehrungen zur Verhinderung des Rückstaus sind ansich bekannt in Form von Klappen oder schwimmenden Kugeln, wie zum Beispiel bei Sinkkästen mit doppelten Rückstauverschluß (DE-B-1 073 406, DE-A 3 243 066). Anregungen zur Lösung der vorgenannten Aufgabe speziell bei einer Ablaufarmatur für Badezimmer der eingangs genannten Art können aus diesem Stand der Technik jedoch nicht entnommen werden.Precautions for preventing the backflow are known per se in the form of flaps or floating balls, such as, for example, in sink boxes with a double backflow trap (DE-B-1 073 406, DE-A 3 243 066). Suggestions for solving the above-mentioned task, especially in the case of a drain fitting for bathrooms of the type mentioned at the outset, cannot, however, be derived from this prior art.

Eine Lösung ergibt sich vielmehr durch die Merkmale nach dem Hauptanspruch der vorliegenden Erfindung. Der Unteranspruch hat eine bevorzugte Weiterbildung dieser Lösung zum Inhalt.Rather, a solution results from the features according to the main claim of the present invention. The subclaim has a preferred further development of this solution.

Bei einer solchen Bodenablaufarmatur sind die den Geruchsverschluß bildenden Elemente so ausgebildet, daß in dem Schachtbereich, wo das Wasser von der Unterkante der Tauchwand her aufsteigt, bevor es über die Stauwand läuft, eine Rückstauklappe passiert, die dabei durch den Wasserdruck selbstätig angehoben wird. Ohne zufließendes Wasser liegt die Rückstauklappe durch ihr Eigengewicht auf und stellt somit eine Sperre gegen rückfließendes Wasser dar. Überdies wirkt diese Rückstauklappe auch zusätzlich gegen aus dem Abwassersystem ankommende Gase. Die Rückstauklappe ist Teil des Einsatzteiles und kann mit diesem zusammen aus dem Topf herausgenommen werden. Die Elemente für die gelenkige Lagerung der Rückstauklappe können dabei angeformt sein. Für die Reinigung ist in der die Rückstauklappe überdeckten Kappe eine verschließbare Öffnung gebildet. Im übrigen hat die Bodenablaufarmatur nach der Erfindung auch ein seitlichen Einlaufstutzen zur Aufnahme von Wasser aus der Badewanne.In such a floor drain fitting, the elements forming the odor trap are designed so that in the shaft area where the water rises from the lower edge of the diving wall before it runs over the dam wall, a backflow flap passes, which is automatically raised by the water pressure. With no water flowing in, the backflow flap rests on its own weight and thus represents a barrier against backflow water. In addition, this backflow flap also acts against gases arriving from the sewage system. The backflow flap is part of the insert and can be removed together with it from the pot. The elements for the articulated storage of the backflow flap can be molded. A closable opening is formed in the cap covering the backflow flap for cleaning. In addition, the floor drain fitting according to the invention also has a lateral inlet connection for receiving water from the bath tub.

Gemäß einer weiteren Ausgestaltung der Erfindung ist eine werkzeuglos zu betätigende Sperrvorrichtung vorgesehen, mit der im Bedarfsfalle die Rückstauklappe in der Schließstellung festgehalten werden kann.According to a further embodiment of the invention, a locking device to be operated without tools is provided, with which the backflow flap can be held in the closed position if necessary.

Die Armatur besteht aus Topf 10 und Einsatzteil 20, beide Teile aus Kunststoff hergestellt.The fitting consists of pot 10 and insert 20, both parts made of plastic.

Am Topf, der im einzelnen auf Fig. 1 und 2 dargestellt ist, ist oben ein Kragen 11 angeformt. Von der zylindrischen Topfwand 12 gehen an einer Seite, bodenseitig, ein Zulaufstutzen 13 aus, und an der gegenüberliegenden Seite ein Ablaufstutzen 14. Beide Stutzen sind angeformt. Im Hinblick auf den Geruchsverschluß schließt der Zulaufstutzen 13 am Topfboden an. Im Anschluß an die zylindrische Topfwand 12 ist ein Absatz 15 gebildet. Im Grundriß ist er durch eine angeformte Stauwand 16, die kreisbogenförmig ist, und von einem querliegenden Kreisdurchmesser 10a ausgeht, an der Ablaufseite ein sichelförmiger Schacht 17 abgeteilt.A collar 11 is formed on the top of the pot, which is shown in detail in FIGS. 1 and 2. An inlet connection 13 extends from the cylindrical cup wall 12 on one side, on the bottom side, and an outlet connection 14 on the opposite side. Both connections are integrally formed. With regard to the odor trap, the inlet connection 13 connects to the bottom of the pot. Following the cylindrical cup wall 12, a shoulder 15 is formed. In plan it is through an integrally formed baffle wall 16, which is in the form of a circular arc and assumes a transverse circular diameter 10a, a crescent-shaped shaft 17 is divided on the outlet side.

Das auf Fig. 3 bis 6 dargestellte Einsatzteil 20 weist einen geschlossenen Kreisring 21 auf, profiliert mit einer Nut, welche einen Dichtungsring 22 aufnimmt. Das Einsatzteil wird in den Raum der zylindrischen Topfwand 12 eingesetzt, wobei sich der Kreisring 21 auf dem Absatz 15 abstützt und der Dichtungsring eine Abdichtung über den gesamten Kreisumfang gewährleistet.The insert part 20 shown in FIGS. 3 to 6 has a closed circular ring 21, profiled with a groove which receives a sealing ring 22. The insert is inserted into the space of the cylindrical pot wall 12, the circular ring 21 being supported on the shoulder 15 and the sealing ring ensuring a seal over the entire circumference.

Das Einsatzteil ist im Grundriß, entlang des Kreisdurchmessers 10a unterteilt in eine Kreishälfte, die zulaufseitig liegt und nach oben offen ist, so daß Wasser von oben her zufließen kann. Im Bereich des zulaufseitigen Halbkreises erstrecken sich vom Ring aus eine halbkreisförmige Tauchwand 23b und entlang des Kreisdurchmessers 10a eine gerade Tauchwand 23a, so daß ein halbkreisförmiger Schacht 23 gebildet wird, der oberhalb des Zulaufstutzens 13 endigt.The insert is in the plan, along the circle diameter 10a divided into a circle half, which is on the inlet side and is open at the top, so that water can flow in from above. In the area of the inlet-side semicircle, a semicircular plunge wall 23b extends from the ring and a straight plunge wall 23a extends along the circle diameter 10a, so that a semicircular shaft 23 is formed which ends above the inlet connection 13.

Die andere Kreishälfte im Ring ist durch eine flache halbreisförmige Kappe 24 abgedeckt, die einen Raum 24a bildet, in dem das hochsteigende Wasser über die Stauwand 16 laufen kann. Im Bereich der Kappe 24 ist gelenkig eine Rückstauklappe 28 gelagert, drehbar um ein Gelenk 28a entlang dem Kreisdurchmesser 10a. Die Rückstauklappe 28 deckt von oben durch ihr Eigengewicht einen segmentförmigen Überlaufschacht 29 ab, in dem das Wasser hochsteigt, bevor es über die Stauwand 16 läuft und in den sichelförmigen Schacht 17 gelangt. Während des Durchflusses wird die Rückstauklappe 28 durch den Wasserdruck angehoben. Sie kann sich dabei in den Raum der Kappe 24 bewegen. Wenn kein Wasser abfließt, liegt die Klappe 28 auf. Bei Rückstau wird verhindert, daß Wasser vom Ablaufstutzen 14 her im sichelförmigen Schacht 17 hochsteigt und in den offenen Teil des Topfes gelangt.The other half of the circle in the ring is covered by a flat semi-circular cap 24, which forms a space 24a in which the rising water can run over the dam wall 16. In the area of the cap 24, a backflow flap 28 is articulated, rotatable about a joint 28a along the circle diameter 10a. The backflow flap 28 covers a segment-shaped overflow shaft 29 from above by its own weight, in which the water rises before it runs over the retaining wall 16 and reaches the crescent-shaped shaft 17. During the flow, the backflow flap 28 is raised by the water pressure. You can move into the space of the cap 24. If no water flows out, the flap 28 lies on. In the event of a backflow, water is prevented from rising from the outlet nozzle 14 in the crescent-shaped shaft 17 and reaching the open part of the pot.

In der Kappe 24 ist eine Reinigungsöffnung 25 gebildet, die durch einen abnehmbaren Deckel verschlossen ist.A cleaning opening 25 is formed in the cap 24 and is closed by a removable cover.

Die Rückstauklappe 28 kann durch einen Finger 27 in der Verschlußstellung verriegelt werden, wobei der Finger, der um eine lotrechte Achse drehbar in der Kappe gelagert ist, eine Stellung einnimmt, in welcher er sperrend auf der schließenden Klappe aufliegt. Mittels eines Hebels 26 oben auf dem Deckel kann der Finger in eine Stellung gedreht werden, wo die Bewegung der Klappe freigegeben ist.The backflow flap 28 can be locked in the closed position by a finger 27, the finger, which is rotatably mounted in the cap about a vertical axis, in a position in which it rests on the closing flap in a blocking manner. Using a lever 26 on top of the lid, the finger can be rotated to a position where the movement of the flap is released.
