Pipe connection for bathtub overflow

The innovation concerns a pipe connection between the lower rolir arch leg one with the bathtub overflow pipe connected pipe elbow and the pipe socket of the bathtub drain valve using a pinch seal held by a union nut, which rests on the circumference of the pipe bend leg.

In the known pipe connections of this type, in which the lower angled Rolir bow leg of the with the Overflow pipe connected pipe bend in the pipe socket of the drain valve protrudes, is to achieve a leak-proof connection between the pipe bend and the

722S929-I.11.72

Pipe socket of the drain valve of the lower pipe bend leg arranged concentrically and coaxially to the pipe socket itself. The pipe socket has an inner diameter that is only slightly larger on than corresponds to the outer diameter of the pipe bend leg. This leads to the fact that the lower Pipe bend legs in the pipe socket of the drain valve must take the same position in each case, which in itself is advantageous.

In practice, however, this leads to difficulties in installing such devices, because more and more Bathtub models come onto the market that have different wall inclinations and, accordingly, the Distance between the bathtub overflow opening and the Drain valve is different seen in the horizontal direction. To take this into account, it has so far been necessary to have one for each type of bathtub special pipe bends to be provided, the lower pipe bend leg of which corresponds to the inclination of the bathtub wall is angled and its leg length to the relevant distance of the drain opening from the overflow opening in the tub base wall is matched. This leads to the disadvantage that every installer has one for every type of bathtub must keep special elbows in stock.

To avoid this disadvantage and for all bathtubs

types rait to be able to use the same pipe bend for the most varied of wall inclinations is planned according to the innovation, that the pipe socket between an arranged at the outer end, inner, the Eohrbogenschenkel with little Game comprehensive ring collar and the wall of the drain valve an inner diameter of about 1.2 to 1.5 times larger has than the outer diameter of the pipe bend leg and that the pinch seal corresponds to a has at least approximately circular cross-section.

In this way, the pipe bend leg is in the pipe socket even given a scope of movement, which makes it possible to bring the pipe bend and the overflow pipe in a position that corresponds to the angle of inclination of the bathtub wall in question is equivalent to. Since it is inevitable that the lower pipe bend leg will not always is arranged coaxially in the pipe socket itself but deviates upwards or downwards from the coaxial position, must also care must be taken that the pinch seal is also in relation to an inclined position of the pipe bend leg on the pipe socket rests tightly on the entire circumference of the pipe bend leg, which according to the innovation is the easiest is achieved in that the pinch seal has an at least approximately circular cross section. Around even with the most varied of distances between the bathtub drain opening and the bathtub overflow opening

Always being able to use the same elbow is another Formation of the innovation provided that the pipe bend smooth two pipe bend legs of different lengths Has ends which can optionally be used in the pipe socket of the drain valve, the length of the one Pipe bend leg to the minimum distance between the drain opening and the overflow opening and the length of the other pipe bend leg on the corresponding one maximum distance is matched.

This has the advantage that the installer for all types of bathtub with the most varied Clearances between the drain opening and the overflow opening can use the same pipe bend, by having a large distance between the drainage hole and the overflow opening to the longer pipe bend leg the pipe socket of the drain valve inserts and with a small distance between the drain opening and the overflow opening the shorter pipe bend leg of the bathtub in question.

An exemplary embodiment of the innovation will now be explained in more detail below with the aid of the accompanying drawing.

The drain valve i a not shown in the drawing

th bathtub has a pipe socket 2, which is soldered with an inner shoulder 3 in the wall k of the ATolaufventils 1 or can also be cast, and which has an inwardly directed collar 3 at its outer end 3. By means of a union nut 6, which is screwed onto the pipe socket 2, a pinch seal 7 having a circular cross-section is pressed against the inner annular collar of the pipe socket 2 and at the same time against the circumference of a pipe bend leg S of a pipe bend 9 pushed into the pipe socket 2. The other pipe bend leg 10 of the pipe bend 9 is connected to the overflow pipe 11. The lower end 12 of the overflow pipe II protrudes into the upper end of the pipe bend leg 10. This connection point is sealed by means of a dimensionally elastic sealing sleeve 13 made of rubber, plastic or the like.

l -. 'ie can be seen from the drawing, is the inner diameter of the pipe socket 2 in the area lying between the collar and the extension 3 is greater than the inner diameter of the tubular bend leg 8 with little play enclosing the annular collar 5, so that the pipe bend leg 3 between the position shown in solid lines and the position shown in dash-dotted lines

is pivotable in all directions by the angle o £. In the various bathtub models that are available on the market, the angle is between 3 ° and 15 °. This pivotability is inevitably also transferred to the essentially vertical one Pipe bend legs 10 and thus also on the position of the overflow pipe 11, so that it is brought into one position can be, which corresponds to the angle of inclination of the bathtub wall on which the overflow device is to be assembled.

As can also be seen from the drawing, the iron two pipe bend legs 8 and 10 of the pipe bend 9 different lengths. In addition, their ends are smooth, i. not provided with a collar or the like. This makes it possible, depending on the distance between the drainage opening in the bottom of the bathtub in which the drain valve 1 is inserted, and the! overflow opening in the foot wall of the Bathtub to insert one or the other pipe bend leg 8 or 10 into the pipe socket of the drain valve 1 and to connect the other to the overflow pipe 11. Au =? For reasons of drawing, the pipe bend leg 8 is shown shorter than in the illustrated embodiment he really is. The overflow pipe 11 can also be in Reality be longer, so that it protrudes deeper into the upwardly directed liohrbogenschenkel 10 and possibly also

veneer with the shorter pipe bend legs 8 v; earth lcann.

The junction between each upward Pipe bend 8 or 10 and your overflow rohi-11 is with a sealing sleeve 13 made of Gunni, plastic or the like. Sealed, as is known per se.

Due to the innovation in accordance with the design of the pipe socket 2 and the pipe bend 9, it is possible for all types of bathtubs each use the same elbow 9 su, so that different elbows are no longer produced and need to be kept in stock.
