Description

• - einen Ablaufkörper mit einer Auslauföffnung,
• - einen Anschlussadapter mit einem kreisrunden Rohrstutzen und
• - einen Ablauftopf mit einer kreisrunden Aufnahme für den Rohrstutzen,

wobei der Ablaufkörper und Anschlussadapter sowie Anschlussadapter und Ablauftopf wasserdicht miteinander verbindbar sind, so dass der Wasserablauf im montierten Zustand einen rohrartigen Ablaufkanal mit einem Innenbereich ausbildet, und wobei am Anschlussadapter eine oder mehrere Durchgangsöffnungen für Schraubelemente vorgesehen sind, mittels derer wenigstens eine Schraubverbindung des Anschlussadapters mit dem Ablaufkörper herstellbar ist.The invention relates to a universal water outlet, in particular for a shower floor, which comprises:

• a drain body with an outlet opening,
• - a connection adapter with a circular pipe socket and
• a drain pot with a circular receptacle for the pipe socket,

wherein the drain body and connection adapter and connection adapter and drain pot are waterproof connected with each other, so that the water drain in the assembled state forms a tubular drainage channel with an inner region, and wherein the connection adapter one or more through holes are provided for screw, by means of which at least one screw of the connection adapter the drain body is produced.

The generic water drains are used in particular in the installation of shower floors in sanitary facilities. These shower floors usually have either a point or channel-shaped drain. Point-like processes are usually arranged in the middle or in a corner of the shower area. Channel-shaped drains are often located close to a wall bordering the shower area.

A round drain pot is for trough-shaped water drains, which are located close to the outside of the shower base, rather unsuitable, since such a drain pot usually has a large outer diameter and thereby obstructs a near-wall installation of the gutter. Therefore, oval shapes have been developed which have a relatively narrow longitudinal region and therefore can be placed closer to an outer edge of a shower base with the same drainage performance. Drainage capacity is the displacement volume of a drain in liters / second.

Such a construction is the DE 10 2014 119 582 A1 to be taken from the applicant. The water drain according to DE 10 2014 119 582 A1 includes, inter alia, a plastic-type connection adapter, called sealing insert, which has a pipe socket and in a drain region inwardly directed projections with through holes for screws. The equipped with such a connection adapter water drain can ensure the required water resistance, but it is not suitable because of its oval shape for any adjustability of the drain pipe. Thus, the drain pipe of the drain pot can only be mounted in a predetermined direction to this connection adapter, either to the left, to the right or obliquely aligned.

It is therefore the task of developing a water flow of the type mentioned in the preamble, which is universally applicable and can meet the requirements of water resistance. In addition, the process should be mounted as close as possible to the outer edge of a shower area.

• - die Schraubverbindungen außerhalb des Innenbereiches des Rohrstutzens des Anschlussadapters liegen,
• - und wenigstens ein Dichtungselement vorgesehen ist, welches die Schraubverbindungen wasserdicht abdichtet.

This object is achieved by a water drain of the type mentioned, in which:

• - The screw connections are outside the inner area of the pipe socket of the connection adapter,
• - And at least one sealing element is provided, which seals the screw waterproof.

The fact that the screw connection of drain body and connection adapter has been moved to the outer region of the pipe socket in the water drain according to the invention, the area increases, which is available for the water to be discharged. In addition, a drain without internal screw elements is favorable in terms of flow and increases the absorption rate of the drain. In order to ensure the water resistance even with this arrangement of the screw, a sealing element is provided. The sealing element prevents water from passing from the drainage area past the screw into the outside area.

As a sealing element, a separate, prefabricated part may be provided in a first embodiment, which is connectable to the connection adapter. This may be a plastically or elastically deformable sealing ring, which is attached to the screw or arranged on the receiving adapter. It is essential that in the preparation of the screw connection between the receiving adapter and drain body, the material of the sealing ring is deformed so far that water can not pass the screw over to the outside. The sealing ring can be firmly attached to the receiving adapter, for example glued, welded or inserted in a clamping area, be.

In a preferred embodiment, the sealing element is integrally connected to the material of the connection adapter. The cohesive connection is preferably formed by welding, coating, scorching or spraying an elastomeric material onto the material of the connection adapter. Also in this embodiment, the sealing element deforms when tightening the screw and seals these off. It is particularly preferred if the material of the connection adapter is stiffer than the material of the sealing element. The sealing element can then crash during assembly against the connection adapter and fill any clearances between the screw surface and screw hole.

In a further preferred embodiment, the sealing element is integrated in an annular seal which surrounds a pipe socket arranged on the connection adapter in an annular manner. The ring seal is plastically deformable, preferably elastically deformable, and preferably has the shape of a circular ring which adjoins the inner region (discharge area) of the pipe socket. The ring seal forms a closed contour around the connection adapter, within which the screw joints and the sections located between the screw joints can be sealed at the same time. When tightening the screw, the drain body is pressed against the ring seal and deformed relative to the contact region of the drain body relatively soft material of the ring seal, so that drain body and connection adapter are connected watertight to each other at this contact point.

The drain body may have a sealing edge, which can be pressed against the annular seal of the connection adapter when the screw connection is made. Preference is given to a narrow or sharp-edged contour of the sealing edge, since such a sealing edge can be pressed into the ring seal with relatively little effort. The sealing element may be designed as a preferably flat ring seal and have an increased, a sealant-like adhesion. In addition, the soft plastic of the ring seal can be pressed sealingly during assembly of the connection adapter to the drain body by tightening the screws.

The screw can be arranged outside the ring seal, so that when tightening the screws, the sealing edge of the drain body is pressed from the outside into the ring seal. To reduce transverse forces, the receptacles for the screw elements can be integrated in the sealing edge of the drain body.

The pipe socket of the connection adapter may be surrounded by a preferably elastic flange, which has a further, the first surrounding and also made of soft plastic sealing element. The further sealing element is preferably located on a peripheral edge of the flange and has the shape of a bead-shaped sealing ring. This results in a second sealing ring around the first ring seal, which prevents the escape of water. In this case, the flange can be polygonal, circular or oval in plan view on its flat side. In view of the possible applications of the connection adapter, however, an elliptical shape of the flange is preferred, which is suitable for point drains and Linienentwässerungen.

The particular advantage is that the pipe socket of the elliptical connection adapter is cylindrical, so that a problem-free connection with a drain pot with arbitrarily aligned or alignable drain pipe can accomplish. In addition, the pipe socket may have a tapered to its free end outer shell on which the drain pot can be used easily.

The sealing elements are preferably made of an elastomeric and water-repellent material, such as a soft plastic from the group TPE (thermoplastic elastomers). The elastomeric material is plastically or elastically deformable and water repellent in a wide temperature range, for example between 5 ° C and 90 ° C. The sealing elements can be made of a plasticizer-free plastic, so that a harmful emission of the plasticizer particles in the bathing room and in the water drainage can be avoided.

Preferably, the passage openings for the screws are arranged in pairs mirror-symmetrical, whereby the pressure forces can be evenly distributed after installation of the connection adapter.

Between the drain pot and the pipe socket, an elastically deformable plate seal may be arranged, which is materially connected to the pipe socket or pulled or pushed in a ring shape on the pipe socket. The lamellar seal can also be loosely placed or glued into a peripheral seat on a pipe extension of the drain pot.

The connection adapter can be made by injection molding or molding from thermoplastic or rubber or hard rubber, preferably from a polycarbonate / acrylonitrile butadiene styrene (PC / ABS) based thermoplastic, such as a PC / ABS blend. A PC / ABS blend has a good processability due to the ABS content and preferred mechanical properties due to the PC components, such as high impact resistance and heat resistance. It is also not excluded, the connection adapter, except sealing rings, made of a non-corrosive metal or metal alloy.

The water drainage according to the invention can be installed both on gutter-shaped as well as punctual sequences. In addition, the water drain can be placed according to the invention at any point of the shower floor, for example, on an outer edge of the shower base plate or in the central region.

The water drain according to the invention can therefore be assembled from modular system elements for point and line processes.
