Description Connection component set for sanitary bodies The innovation relates to a connection component set

for sanitary bodies, with a flush water connection pipe and a pull-on onto the connecting pipe Sealing sleeve for insertion into the flush water pipe socket of the sanitary body, e.g.

toilet body, preferably with a sealing sleeve, which has an inwardly projecting ring collar at one end to

Attachment with one front edge of the

flushing water connection pipe. 10

The well-known flushing water connection pipes are

Pipe socket of this sanitary body the required

Sealing between these parts is achieved. The sealing sleeve is placed on the flush water connection pipe in such a way that its inwardly projecting ring collar is in contact with one end edge of the flush water connection pipe. However, there is a risk that when the flush water connection pipe is pushed into the pipe socket of the sanitary body, the sealing sleeve will slide onto the smooth cylindrical connection pipe. In such a case, the sealing sleeve will only perform its function inadequately or not at all. It should be noted that the perfect fit of the sealing sleeve cannot be visually checked after assembly, as the sealing sleeve is covered by the flush water pipe socket of the sanitary body.

The innovation is therefore based on the task of avoiding the above-mentioned defects and providing measures that enable a perfect installation of the flush water connection pipe with the sealing sleeve pulled on the sanitary body, so that after installation the sealing sleeve is always in the correct sealing position.

According to the innovation, the above task is solved by providing the flushing water connection pipe on its outer circumference with a circumferential or segmented stop for the front face at the other end of the sealing sleeve, which is located opposite the end with the inwardly projecting ring collar. When assembling or inserting the flushing water connection pipe with the sealing sleeve pulled on into the connection pipe socket of the sanitary body, the sealing sleeve lies with

its outward-facing front surface against the stop on the flush water connection pipe, which ensures that the sealing sleeve is taken into a perfect sealing position when the flush water connection pipe is pushed further into the sanitary body. In other words, the stop on the flush water connection pipe reliably prevents the sliding of the sealing sleeve onto the flush water connection pipe, which has previously been observed during assembly. At the same time, as is known, the ring collar of the sealing sleeve rests against the inner front edge of the flush water connection pipe.

One embodiment of the innovation is characterized in that the stop consists of a ring collar or ring collar segments molded onto the flush water connection pipe. This molding of the ring collar or ring collar segments onto the flush water connection pipe, which is usually made of plastic, is a simple measure that hardly increases the manufacturing costs of the connection pipe.

If, according to yet another embodiment of the innovation, the sealing sleeve has several sealing lips with a sawtooth-shaped cross-section on its outer circumference and the flanks of the sealing lips facing the stop on the flushing water connection pipe each enclose a right or approximately right angle with the axis of the sealing sleeve with their extensions, the sealing lips generate less frictional resistance when assembling the structure consisting of the flushing water connection pipe and the sealing sleeve.

Another significant advantage of the innovation is that the inner diameter of the inwardly projecting ring collar on the sealing sleeve is now

the state of the art can be dimensioned in such a way that it corresponds to the inner diameter of the flushing water connection pipe. Previously, the inwardly projecting ring collar of the sealing sleeve was partially in the clear cross-section of the flushing water connection pipe, which caused undesirable turbulence when the flushing water flowed in.

The innovation is then explained using a drawing of an example. Shown are:

Fig. 1 is a side view of a wall-mounted toilet body, partly in section, to show in particular the sealed flush water connection pipe and

Fig. 2 shows a longitudinal section of the flushing water connection pipe according to the innovation with the sealing sleeve fitted and ready for installation.

The reference number iO in Fig. 1 denotes a sanitary ware in the form of a wall-mounted toilet body which has a molded flush water pipe socket 11 and a waste water pipe socket 12. A waste water connection pipe 13 is connected in a sealed manner to the waste water pipe socket 12, while a flush water connection pipe is installed in a sealed manner in the flush water pipe socket 11.

The flushing water connection pipe 14 is preferably made of plastic and has on its outer circumference, for example, a circumferential stop 15, which is designed here as a molded-on ring collar. The circumferential stop 15 acts in conjunction with one end face 22 of a sealing sleeve 16, which is attached to the according to Fig.

·

left end of the flushing water connection pipe 14. In this ready-to-install state, a radially inwardly projecting annular collar 17 of the sealing sleeve 16 rests against one end edge 18 of the flushing water connection pipe 14.

The sealing sleeve 16 has several circumferential sealing lips 19, which have a sawtooth-shaped cross-section. The flanks 20 of the sealing lips 19 facing the circumferential stop 15 run in planes which enclose a right angle with the axis 21 of the sealing sleeve 16 or the flush water connection pipe 14. This reduces the frictional resistance when inserting the structure shown in Fig. 2 into the flush water pipe socket 11 of the toilet body 10, thus making the assembly of the flush water connection pipe 14 easier.

It is particularly emphasized that the inner diameter D of the ring collar 17 of the sealing sleeve 16 corresponds to that d of the flushing water connection pipe 14. When the structure shown in Fig. 2 is pushed into the flushing water pipe socket 11, the inwardly projecting ring collar 17 rests against one end edge 18 of the flushing water connection pipe 14 and, in addition, the sealing collar 16 rests with its right-hand end face 22 as shown in Fig. 2 against the stop 15, which prevents the sliding of the sealing sleeve onto the connection pipe as observed in the prior art and the associated disadvantages.

The flush water connection pipe 14 and the waste water connection pipe 13 are usually connected to building-side bends or pipes (not shown).
