Description

The invention relates to a drain fitting for shower or shower trays an odor trap housing that on the tub in the area of Tub duct can be fixed by connecting a cover part to an outlet pipe is and via a reaching into the still water area of the housing and the dip tube, which specifies the odor trap, and a drain pipe protruding to the side disposes.

From DE-GM 19 56 597 is a drain fitting for sinks, sinks and the like are known, in which the drain of the basin or the tub used drain valve body a vertical adjustment tube is slidably mounted. Due to the telescopic adjustment tube, there is the possibility in the tub or to precisely specify different water levels in the pool. As an odor trap a common knee is present, due to the accumulation of a standing water area in the U-shaped part it is avoided that sewage smell in the area of the outlet flows back. The tub rim is between the outlet pipe and a bracing screw so clamped that the entire fitting is fixed.

From EP-A-558 979 a further drain fitting is known, which is an integrated one Has adjusting tube that can be moved telescopically. The adjustment tube can from a normal position in which its outlet opening is arranged so deep that the water can flow freely, be pulled into an upper position, the is defined by a stop. The water then flows through the overflow opening of the adjusting tube, so that the water up to this height of the pulled-out adjusting tube defined can be pent up. However, it is only possible to do this one Set maximum position, intermediate positions cannot be maintained. There Such shower bases do not have a standardized depth or height is such an overflow device not always suitable. The housing has a lid on the tub is arranged braced. Housing and lid are made of plastic and are direct connected to the outlet pipe, so that for each individual tub type or thickness Different housings or lids must be used in the tub wall. This is also necessary because the immersion pipe attached to the outlet pipe only remains in the specified position. Should the tub floor become thicker prove to be pre-planned or should insulation or the like be additionally provided, Accordingly, another, d. H. longer or shorter dip tube and a other housing can be used. The interior of the housing is namely through a molded, flat dam wall divided into a standing water area and one segment-shaped drainage space from which the drainage nozzle continues. In the storage space the water level always remains at a certain level regardless of the inflow, so that the odor trap is present.

The invention is therefore based on the object, one with a few simple steps to be assembled, adaptable to different wall thicknesses and conditions and to create a drainage fitting ensuring a secure odor trap.

The object is achieved in that the drain pipe Tub shows a guide socket in which the dip tube up to one Minimum distance to the bottom of the housing is arranged displaceable distance is.

The dip tube is practically different from all known solutions supported the floor and kept at a certain distance from it, so that the Waste water can pass through easily and penetrate into the storage space and from there over the drain pipe can drain off. The dip tube can thus in the area of the outlet pipe be moved and depending on the length of the guide pipe assigned to the outlet pipe held in different positions depending on the thickness of the tub floor become necessary without changing the immersion tube or the housing is. This variability of the housing is further supported by the fact that the cover part and Housing form a unit, thus also on the outlet pipe or the guide socket can be adjusted in height to accommodate the different wall thicknesses and other circumstances to adjust easily. Both are therefore advantageous Adaptability as well as the simple handling and the simple training of the entire housing, now dispensing with a special wall or partition can be because the actual dip tube together with the baffle for one appropriate odor trap.

An always safe drainage of the dirty water while maintaining the odor trap is given in particular by the fact that the dip tube is preferably three, the bottom associated side webs is arranged supporting, so as an end stop to serve. This leaves enough space for the drainage of the dirty water available, always safely under the lower edge of the dip tube in the area of the storage space can flow into it. This ensures that the dip tube is always is longer than the dam wall, so that the height of the sealing water remains secured. Through the The use of three side bars is a safe support and storage of the dip tube always guaranteed. On the other hand, adequate drainage protection for the Dirty water available.

Another expedient embodiment of the invention provides that one in the dip tube telescopically displaceable adjusting tube with cover cap is arranged. The adjustment tube can advantageously be set in the housing according to the respective needs be so that a certain water level is guaranteed in the tub. The dip tube can be easily pushed to different and desired heights or raised to specify the water level in the tub. It is a practically infinite adjustment or change possible, because that in the dip tube guided adjustment tube is rotatable relative to the dip tube and cover cap and via a guide corresponding to a guide formed on the inside of the dip tube helical or spiral guide rail. This training provides Adequate self-locking so that the adjustment tube is at the respective pull-out height remains, even if the user releases the adjustment tube.

On the one hand to ensure a favorable support on the side bars and on the other hand to avoid pulling the immersion tube too far the invention proposes that the immersion tube has a pull-out protection on the bottom, preferably in the form of an outwardly projecting annular approach. How This approach also acts as a wider support zone and stability or support for the immersion tube.

The displaceability of the immersion pipe in the area of the outlet pipe is thereby ensured that the dip tube at the end opposite the floor with a O-ring seal is equipped. This O-ring seal grinds on the inside wall the guide socket of the outlet pipe, so that the water is always even in the Area of the storage space is introduced.

An advantageously stable overall housing is available, which with the adjustment of the Immersion tube can be brought into the correct position at the same time, because with the outlet pipe connected lid part of the housing with the lower housing part connected, preferably welded. A separate attachment is therefore not required of the two parts of the housing, but rather the overall housing, as described, by connecting the outlet pipe to the cover part at the same time effectively set.

It was pointed out earlier that the definition of the Drainage fitting on the bottom of the tub is done in that different parts against each other be clamped, which is the cover part and the outlet pipe acts. In order to be able to handle this bracing easily and always safely, it is provided that that cover part and outlet pipe have corresponding threads.

On the one hand for secure tensioning at the bottom of the tub and on the other hand around The best possible stability must also be guaranteed for the entire housing provided that the cover part is L-shaped or N-shaped in section and with the the thread or one of the short legs with the lower housing part is welded. This is opposite for the arrangement of the seal and the support an optimal area is predefined for the underside of the tub or the tub bottom, while the corresponding webs weld cheaply to the housing wall, d. H. get connected. It is expedient if these also collide Walls have side bars that enlarge the weld, these usually protrude outwards from the wall.

Compared to the tub or the bottom of the tub, a seal to Housing made out, being a safe and always the same arrangement this flat seal is possible in that the long leg of the cover part has a portion receiving the flat seal. This section ensures that the flat seal is always arranged the same and thus also against the bottom the bottom of the tub is pressed. To overload this above To avoid thighs, it is provided that the long and the short leg in Area of the section are connected via angular reinforcing struts, so that a correspondingly wide projection of this leg is easily possible.

To simplify assembly, it is additionally provided that the seal is glued at the factory to the leg, so that only during assembly screwing or connecting the cover part and drain pipe via the threaded connection is necessary.

Depending on the size of the spout in the bottom of the tub and also to avoid it of tensions in this area, it may be appropriate to discharge pipe and guide socket assigned at a distance from each other and over one, at the level of the tub to connect the extending support web. This design leads to the fact that Immersion tube is kept quite flexible, but is still securely guided and fixed.

This ensures an even flow of water out of the tub, that the cover cap has at least one hole off-center. It can so that there is no backflow in the housing.

If you are not working with an adjustment tube, it is an advantage if the cover cap is releasably connected to the outlet pipe via a snap hook in order to remove the cover cap if necessary so that the tub runs empty can. About the snap hook closure is a simple way Necessary detachable connection created. For the extension of the dip tube or for pulling out or pushing in, it is advantageous if the outlet pipe has an extension with a latch, which is in notches on the outside the upper end portion of the dip tube is arranged engaging. This can a very precise and fine adjustment of the dip tube can be accomplished so that an exact assembly of the drain fitting is guaranteed.

In the described embodiment, the dip tube can advantageously be of be introduced above, which is advantageously possible in that the Dip tube has a sharpened edge on the side facing the ground. A pull-out protection can be dispensed with here because the latch and the Notches automatically provide pull-out protection. It is a particularly stable one Execution thereby ensures that several, preferably distributed over the circumference three locking lugs are provided, which extend into the standing water area are. This is also a sufficiently long extension length for the dip tube predetermined and thus the desired adaptation to different circumstances, especially on different wall thicknesses.

The invention as a whole is characterized in that one can be carried out in a few simple steps drain fitting to be assembled and securely assembled, which advantageous easily to different wall thicknesses of the tub or other conditions can be adjusted. It can always be with the same housing with the cover part be worked without any adjustments. Depending on the training the drain pipe or the guide socket, it is possible, even with extreme thick insulation or similar to securely fix the drain fitting described. Advantageous is further that such a drain fitting also with a telescopic adjustment tube can be equipped without special additional measures requirement. The adjustment tube is rotatably held in the immersion tube and can by the Incline of the helical or spiral guide rail in any position be locked so that different water levels in the tub are set favorably and can be met. The extension of the dip tube can be convenient by a locking lug assigned to the outlet pipe and assigned to the immersion pipe Notches can be set precisely. It is also an enormous advantage that the Housing consisting of cover part and lower part of the housing is automatically adjusted as a whole is when the described adaptation to different circumstances the dip tube is made. In addition, the housing forms a stable unit, because the cover part and the lower part of the housing are welded together.

Fig. 1 shows a drain fitting 1, to a tub 2 or the tub floor 3 is mounted. The drain fitting 1 has a housing 4 with a cover part 5 and Lower housing part 6. Lid part 5 and lower housing part 6 are permanently connected to one another. Details on this will be explained further below.

The housing 4 is pot-shaped, with between the bottom 7 and the lid part 5 an odor trap 8 is provided, which is achieved in that within the housing 4 pot walls 9 or baffle walls 13 a standing water area or Secure storage space 10, into which the dip tube 11 protrudes, so that the dip tube 11 introduced waste water must overflow over the dam 13 before it enters reaches the area of the drain pipe 12 and thus flows away. It remains in the stagnant water area 10 or in the storage space always water back, so that negative smells cannot exit.

According to FIGS. 1 and 2, an adjusting tube 15 is telescopic in the immersion tube 11 arranged and formed over a cover cap 16 so that in the inserted Position, which is not quite reached in Fig. 1, the tub 2 with respect to the drain pipe 12 can be completed. The cap 16 is rotatable relative to the Adjustment tube 15 so that this is forced through the guide 17 and the guide bar 18 can rotate without the cover cap 16 also rotating. The guide bar 18 is screw or arranged spirally here on the outer wall of the adjustment tube 15, so that when pulling the adjusting tube 15 through the guide 17 on the inner wall 19 of the dip tube 11, the turning process for the adjusting tube 15 is forced. The guide bar 18 and the guide 17 ensure self-locking, so that the adjusting tube 15 in any position, i.e. H. Pull-out position is automatically locked, naturally also in the maximum extension position shown in FIG. 2. The self-locking is increased by the O-ring 20 and at the same time it ensures that water cannot flow along this narrow gap, but rather always is forced to flow through the adjustment tube 15. The O-ring 20 acts together with the pull-out protection 21 at the upper end of the dip tube 11, so that the adjusting tube 15 is also accidentally removed from the dip tube 11 can be pulled out.

The dip tube 11 itself is at the end facing away from the bottom 7 with an O-ring seal 22 equipped, which is fixed in the groove 23. This O-ring seal too 22 serves for sealing and at the same time for sliding on the inner wall of the guide socket 31. This makes it possible, depending on the thickness of the tub bottom 3 To move the immersion tube 11 in the guide socket 31 of the outlet tube 28. The lower The end of the dip tube 11 has a pull-out protection 24 in the form of an annular one Approach 25. This pull-out protection 24 is in all representations of the figures 1 to 5 the same.

When installing the drain fitting 1, it is clamped to the tub base 3 namely by either housing 4 with cover part 5 on the outlet pipe 28 is rotated, both of which have a thread 29, 30 or by the Outlet pipe 28 is rotated relative to the housing 4 or the cover part 5. Of the Comparison of Figures 1 and 2 shows that a safe assembly with one and the same Drain fitting 1 is easily possible because the practically one-piece housing 4 is to be fixed securely to the tub floor 3, always while respecting the same position of the dip tube 11. It can be seen that this dip tube 11 after FIG. 2 is practically positioned at the upper end of the outlet pipe 28, according to FIG. 1 in contrast, almost at the lower end of the guide socket 31 of the outlet pipe 28.

This always the same position of the dip tube 11 with respect to the baffle 13 or the pot wall 9 is, according to FIGS. 1 and 2, by an annular attachment 42 reached on the floor 7. This is shown in Fig. 3. It can be seen that this ring-shaped attachment has side webs 43, 44 directed towards the center 46, a total of three side webs 43, 44 for the stable mounting of the immersion tube 11 are provided. At the free ends of these side webs 43, 44 there are recesses 45 provided, into which the lower edge of the dip tube 11 is inserted. Because the dip tube 11 has at the lower end the already mentioned annular extension 25 is so secure support achieved or guaranteed.

First, a secure bracing of the drain fitting 1 to the tub floor 3 to achieve and secondly to provide an effective seal against the bottom to accomplish, the cover part 5 is formed in cross-section N or L-shaped. According to Figures 1 and 2, an n-shaped design is provided, the short Leg 33 with its molded-on side web 40 for connection to the corresponding one Wall of the lower housing part 6 is used. The second short leg 35 is yours Provide thread 30, which corresponds to the thread 29 of the outlet pipe 8 or the guide socket 31 is formed.

The long leg 34 connecting the short legs 33, 35 is over the out short leg 33 and with a portion 36 for receiving the flat Seal 37 executed so that the effective and always the same seal is given opposite the underside of the tub bottom 3. About the in Fig. 1 and 2 recognizable reinforcing struts 39 the necessary stability is ensured.

It has already been mentioned earlier that the difference between FIG. 1 and FIG. 2 not only in the different extension width of the adjusting tube 15 is seen, but also in the formation of the warning floor 3.

1 is a tub insulation on the underside of the tub floor 3 38 provided that a corresponding change to the drain fitting 1 or Housing 4 is not required because, as explained above, the immersion tube 11 has its position always maintains regardless of the thickness of the tub bottom 3. It is supported on the bottom 7 or on the ring-shaped attachment 42.

Fig. 4 shows a section through a drain fitting, in which deviates from the 1 and 2, a very thin-walled tub 2 with a tub bottom 3 is connected. The cover part 5 is in its n-shaped design in section advantageously rounded or curved and has a surface that has already been fixed in advance Seal 37 on. This flat seal is already glued on in the manufacturing plant.

Deviating from the representation according to FIGS. 1 and 2 is also according to FIG. 4 the adjusting tube 15 and in particular the immersion tube 11 not on the bottom 7 of the Lower housing part 6 is supported, but rather on the floor 7 facing away Page 50 over the collar 51. The side 52 assigned to the base 7 thus remains unsupported. Again, there is an O-ring seal 22 for sealing against that Drain pipe 28 available.

The cover cap 16 has an eccentric bore 53 through which a vent of the storage space or the backwater area 10 is possible at any time. A There is always pressure equalization.

It can also be seen in FIG. 4 that the drain pipe 28 through the tub passage 14 pushed through and screwed to the cover part 5, d. H. so connected is.

FIGS. 5 and 6 again show an embodiment corresponding to FIGS. 1 and 2 of the housing 4 with differently thick tub floors 3. It can be seen that here, too, the immersion tube 11 is opposite the outlet tube 28 or the guide socket 31 is in a different position, opposite the floor 7 or Storage wall 13 but in the same position, so that the odor trap 8 independently of the thickness of the tub bottom 3 is always guaranteed.

The cover cap 16, not shown in FIGS. 5 and 6, is shown in FIG. 7. This too Cover cap 16 is provided with an eccentric bore 53. It will over Snap hook 54 connected to the outlet pipe 28, so that this cover cap if necessary 16 can be easily removed or put on.

Deviating from the representation according to FIGS. 5 and 6, there is additionally one here Fine adjustment of the dip tube 11 possible in that an extension 55 Outlet pipe 28 is provided, which carries a locking lug 56 at the end. Because on the outside 57 of the upper end portion 58 of the dip tube 11, many notches 59, 60 are provided are, the respective position of the dip tube 11 can be practically arbitrary can be set.

Because of this special training, it is also advantageously possible here Insert the immersion tube 11 into the outlet tube 28 from above. For relief a lower cut edge 61 is provided.

5 and 6, the cover part 5 is in cross section also formed n-shaped, whereby the same seal or the same Position of the flat seal 37 results in turn independently of the respective thickness of the tub bottom 3.

8 and 9 in turn show a tub floor 3 in different Strength by changing the extension of the dip tube 11 to the outlet pipe 28 or the guide connector 31 is not a problem due to different thickness. The adjustment is practically the same as that described earlier Assembly.

Compared to the embodiments according to FIGS. 1, 2 and 4, there is a change on Outlet pipe 28 has been made. The outlet pipe 28 and the guide socket 31 are connected to one another in the region of the tub floor 3 via a support strut 48 and arranged at a distance so that here the larger width of the hole or the tub passage 14 in the tub floor 3 can be taken into account. A further training of this type is advantageously insensitive to faults. The dip tube 11 is on the guide socket 31 out, including the groove 23 and the O-ring seal, not shown here 22 serve as a supplement.

10, a cover cap 16 is shown, which has a Snap hook connection 54 can be connected to the outlet pipe 28 if the spout should be blocked.

11 shows the practically infinitely variable reproduction Adjustment of the dip tube 11 in that on the outside 57 of the dip tube 11, a plurality of notches 59, 60 are provided in the upper end section 58, into which as can easily be seen in Fig. 11, the latch 56 of the extension 55 of the outlet pipe 28 can engage, so that the immersion tube 11 is effective in any position to be determined.

The locking lug 56 is a correspondingly narrow attachment strip to the outlet pipe 28, expediently not only such a locking lug 56 distributed over the circumference is provided, but several, and if possible three.

All of the above-mentioned features, including those that can only be taken from the drawings, alone and in combination are regarded as essential to the invention.
