Description

Pipe connection for toilet basin.

The invention relates to a pipe connection for lavatory basins elastic material, consisting of a pipe sleeve that can be pushed onto the drainage connection of the toilet basin, one in the disposal line insertable pipe piece and an intermediate piece opposing both parts.

With such pipe connections are for sealing between the Pipe socket and the drainage socket of the toilet basin several elastic, ring-shaped ribs on the inside of the pipe socket

formed, with at least two such ribs sealing one another must place on the drainage nozzle. In order to achieve this, the drain connection must necessarily have a considerable length. The lavatory basins, such as the so-called Euro basins, often have only short drainage nozzles, so that one

perfect sealing is often not guaranteed by the sealing ribs.

In addition, the lavatory basins are often not positioned with their drainage connection towards the disposal line centered., so that the pipe connection is pushed onto the drain socket and tilted when pushed into the disposal line and in this case too, a pipe connection of the type described above will not result in a perfect seal can.

The invention has the task of to form a pipe connection of the type mentioned in such a way that the foregoing disadvantages are eliminated, that is, even with a short discharge nozzle of the toilet bowl and even in relation to the disposal line inaccurately attached abortion Beeken an \ absolutely tight connection between toilet bowl and Disposal line is achievable.

According to the invention this goal is achieved in that in the Pipe socket a pipe sleeve which is connected only to the upper edge of the socket and can be pushed onto the drainage connection is formed and which The pipe socket has annular elastic ribs on its inside, which at least approximately up to the pipe sleeve pass.

By being supported by the annular elastic ribs The pipe sleeve is pushed onto the drainage socket of the toilet basin an extremely secure, firmly sucking seal is achieved between the pipe connection and the drainage cap. Through the annular elastic ribs on the inside of the pipe socket an optimal seal is created between the pipe sleeve and this pipe socket, even with a rough and partially oval one Shape of the drain connection respectively. one to the disposal line Ensure that the drainage connection is not precisely aligned.

The annular ribs preferably run obliquely to the longitudinal axis of the pipe connection and point away from the pipe section that can be inserted into the disposal line. In addition, the sleeve extend approximately to the intermediate piece.

The Rohransehluß shown consists of elastic material; such as plastic. It has a pipe socket 2, which via an intermediate piece 3 iait a cylindrical pipe section ² I-

is connected, which has a smaller diameter than the pipe socket 2 and is pushed into a disposal line 1. The pipe socket 2 has an annular shape on its inside Ribs 5> which run obliquely to the longitudinal axis of the pipe connection and point away from the pipe section 4 which can be inserted into the disposal line. This piece of pipe. 4 has sealing ribs 6 on its outside.

In the pipe socket 2 sits a pipe sleeve 7 which is made in one piece with the pipe socket and is connected to the upper edge of the socket, while it protrudes freely movable into the pipe socket up to the intermediate piece J>.

The annular nipples 5 on the inside of the pipe socket 2 extend approximately to the pipe sleeve 7 and form an elastic support for this when the pipe sleeve on the Drain supportii 8 of the lavatory basin is pushed on. The one at the Ribs 6 formed on the outside of the lower pipe section 4 ensure when this pipe section is pushed into the disposal line 1 there for a perfect seal.

When installed, the annular ribs 5 air-filled chambers formed between the pipe socket 2 and the pipe sleeve 7, whereby a particularly great flexibility of the Pipe sleeve is achieved, while at the same time an extremely effective seal between the pipe sleeve 7 and the drain port δ arises.

The pipe connection is preferably produced in an injection molding process in a die which consists of a two-part outer jacket and a core. This die is designed in such a way that at the free end of the pipe section 4 a bottom piece is formed and that the pipe sleeve 7 is formed as a narrowed pipe end on the pipe socket in the dot-dash position in Pig.i. will.

After completion of the injection molding process, the two-part outer shell of the die is opened and air is blown into the still hot and consequently very flexible molding through the open tubular sleeve 7, which points upwards, as shown in dash-dotted lines. As soon as the shaped piece and in particular the sleeve piece 7 is inflated so far that it can be pushed over the thicker core piece to form the pipe socket 2, the pipe socket is pressed off from the core. Then the bottom section formed at the lower end of the pipe section K is removed and the pipe section pointing upwards is folded inwards into the pipe socket so that it assumes the position shown in FIG. 2 as a pipe sleeve 7. The pipe connection according to the invention is thus ready.

While only one embodiment has been explained above, the invention can of course be modified in various ways within the framework of the respective circumstances.
