Definitions

  • the invention relates to a drain fitting for shower trays or shower trays with a two-part drain housing, a fixed immersion pipe and an adjusting pipe which is telescopically displaceable therein, which carries a cover cap in the area of the overflow opening and is equipped on the outside with sealing elements and stops which specify the end positions.
  • an overflow device for wash basins, sinks and the like in which a vertical adjustment tube is slidably mounted in a drain valve body used in the drain of the basin.
  • the telescopic adjustment tube allows you to precisely set different water levels in the sink or sink.
  • the adjustment tube is fixed in any position using friction seals, whereby due to the moisture that is always present and the friction that has occurred, a precise setting can no longer be guaranteed after certain idle times.
  • This overflow device is provided for pools with an overflow channel.
  • Another drain fitting is known from EP-A-558 979, which has an integrated adjusting tube which can be moved telescopically.
  • the adjustment tube can be pulled from a normal position, in which its outlet opening is arranged so deep that the water can flow freely, into an upper position, which is defined by a stop.
  • the water then flows out through the overflow opening of the adjusting tube, so that the water can be dammed up to this height of the pulled-out adjusting tube.
  • Such a drain fitting can be used particularly advantageously for shower trays or shower trays because it can be used to specify a certain water level.
  • this is problematic for shower trays or shower trays if they are used with a particularly low height come because the adjustment tube can only be secured in two positions. Since shower bases do not have a standardized depth or height, such an overflow device is therefore not always suitable.
  • the invention is therefore based on the object of creating a drainage fitting with a permanently easy-to-operate adjustment tube which can be "locked” in a plurality of positions which can be selected in any desired manner.
  • the adjusting tube is rotatable relative to the dip tube and cover cap and, together with the dip tube, has a helical or spiral guide.
  • the adjustment tube can be extended practically with any length compared to the immersion tube, where the adjustment tube remains in the predetermined position due to the self-holding of the spiral guide, so that a water level is set practically independent of the respective depth of the shower tray or shower tray will. If the water is then to flow off completely, the adjusting tube is simply moved into the lower position by exerting pressure on the cover cap, without the risk that inaccuracies can occur due to frequent use or due to moisture when the adjusting tube is pulled out again. There can be no wear and tear because the self-locking device has to be used to fix the adjustment tube in different positions.
  • the guide is designed as a spiral groove embedded in the adjusting tube and a guide pin assigned to the dip tube.
  • This guide can be easily manufactured, especially since such an adjustment tube can be made of plastic, so that the groove can be realized in the manufacturing process.
  • the guide pin can be assigned to the dip tube during manufacture, so that the special guide mentioned here is very easy to manufacture and is characterized by optimal effectiveness.
  • Uniform and secure guidance is achieved in particular if a plurality of grooves and guide pins, preferably a second groove and a second guide pin, are provided.
  • the up and down movement can thus be evened out and optimized even more, the production being simple here too, because a separate second processing of neither the adjustment tube nor the dip tube is required.
  • This training is also characterized by the fact that the corresponding additives for guiding during the manufacturing process of the individual parts can be taken into account and manufactured at the same time, so that a separate machining process is not required. This also ensures that the adjustment tube can be stopped practically in any position, so that any water level can be achieved without the need for separate components or a subdivision of the adjustment tube or other solutions.
  • a uniform "adjustment" of the adjustment tube seen over the height is ensured by the fact that the spiral groove has a constant slope.
  • the precise adjustment of the adjustment tube can be ensured by this predetermined slope, and as mentioned several times at any height.
  • the constant slope is easy to achieve.
  • the desired height is easy to set.
  • the spiral groove has an increasing gradient towards the overflow opening, because it can be assumed that relatively low settings are required more frequently than practically very high settings. Due to the initially lower gradient, a millimeter adjustment can be implemented in a simple manner.
  • the lower slope makes the automatic resetting of the adjustment tube even more difficult.
  • the individual parts are coordinated with one another, so that, for example, correspondingly suitable immersion tubes and adjusting tubes form a unit with the respective drain housing.
  • this is not necessary, i. H. it is also possible to use pipes with a smaller or larger diameter, since the drain housing has a cover part which snaps into the lower housing part and is designed as a reducer, and which is at the same time designed to fix the immersion pipe with a fastening nut.
  • the fastening nut can also be designed as a locking part, so that only the individual parts have to be locked together in order to then have a complete drain fitting available.
  • the reducer which also serves as a cover part, is to be changed or exchanged if dip tubes and adjusting tubes of a different diameter are desired. This may be necessary in particular in the case of particularly large or particularly small shower trays or shower trays. Overall, it is also advantageous that the reducer also effectively fixes and holds the dip tube and thus also the adjustment tube.
  • cover cap and the adjusting tube are rotatably and detachably connected to one another by means of a locking piece.
  • the locking piece also forms the "joint", via which the adjusting tube can be rotated relative to the cover cap without it rotating. Due to the detachable connection via the locking piece, the adjustment tube can be replaced if necessary, by simply removing the cover cap, so that the adjustment tube can then simply be pushed out through the immersion tube.
  • Flawless guidance and thus latching or locking in any position is achieved with a groove which has flanks and groove base extending at right angles to one another or an arcuate groove base. So that the guide pin is guided safely and sufficiently and can easily accommodate the dead weight of the adjusting tube if the locking is determined in a designated position by simply removing the pressure or the tensile force on the adjusting tube from the latter.
  • the described design of the groove ensures a sufficient lifespan.
  • the groove is that in which it has obliquely inwardly extending flanks or is designed to be V-shaped and that the guide pin is given a corresponding shape. It is sufficient that so much friction is generated due to the shape of the groove and guide pin that the adjustment tube remains in the intended position even when the user lets go of it.
  • the groove has obliquely outward flanks and the and the guide pin have an adapted shape. This training is particularly advantageous if only one groove and one guide pin are used because the frictional forces achieved in this way are greater than with the open shape of the groove.
  • the conditionally required friction between the groove and the guide pin can also be set in a targeted manner in that the guide pin has an all-round projection at the free end and a relief slot running in the axial direction in the middle.
  • This special shape means that the free end, ie the actual leading end of the guide pin with its projections, ie the Outer edge pressed against the flanks of the groove, so that the necessary locking is always ensured in the desired position even in the presence of moisture or even with foam or even detergent in the water.
  • the relief slot is wedge-shaped and points with the wedge tip from the free end and leads up to the projection of the projection, because the desired spring action of the guide pin end is then ensured.
  • Another embodiment of the end of the guide pin is that in which the free end of the guide pin has several, preferably three spring feet projecting outwards.
  • This design of the guide pin end ensures that at least two of the spring feet always rub against the flanks of the groove, so that the desired locking is achieved, in particular even when the ends of the spring feet are rounded off, so that damage to the flanks of the groove does not occur can, but rather the advantageous conditional friction is generated.
  • the guide pin thus has the shape of a molar tooth, and there is no fear of the spring feet breaking off even with frequent use.
  • an embodiment of the guide pin is advantageous in which it has a guide ball which is rotatably mounted at the end and can be displaced against the force of a spring in the guide pin.
  • the guide ball is thus always held with a certain pressure on the groove base, which ensures the desired locking in any position.
  • it is impossible to influence the spring or the guide ball so they can both be made of plastic, for example. Since the guide ball can still be rotated despite the spring, it always lies on the groove base with a different surface, so that sticking or, on the other hand, accidental sliding cannot occur.
  • the invention is characterized in that a drain fitting is created which is simple to manufacture because the parts required for guiding the adjusting tube in the immersion tube are also realized in the manufacture of these two components of the drain fitting.
  • a drain fitting is created which is simple to manufacture because the parts required for guiding the adjusting tube in the immersion tube are also realized in the manufacture of these two components of the drain fitting.
  • Through this targeted guidance of the adjustment tube it is possible to pull it out in any length and to realize different water depths or heights.
  • a self-locking can be achieved which ensures that the position specified by hand is maintained without any additives.
  • the groove / guide pin guide is not subject to wear and practically also forms the necessary seal between the immersion tube and the adjustment tube, so that additional additional components can be dispensed with entirely.
  • the individual components of the drain fitting can be connected to one another simply and securely, and so that the exact fit of the dip tube and the adjustment tube is then also guaranteed. It is also advantageous that the special design and arrangement of the immersion pipe and adjusting pipe as well as the drain housing enable simple and safe odor control to be achieved. A skilful design of the groove and the guide pin ensures that there is a targeted and sufficient friction which ensures that the adjusting tube is locked in any desired position.
  • the fitting 1 shown in Fig. 1 has a laterally attached further water pipe, which is attached to the drain pipe 9.
  • the drain connector 9 itself is connected to the drain housing 2 in a watertight manner via a union nut 10 and wedge seal 11 and pressure ring 12.
  • the drain housing 2 consists of a pot-like lower housing part 3 with the odor barrier insert 13 and the lower housing part 3 to be connected to the cover part 4.
  • This cover part 4 has a special shape in that it is realized here as a reducer 5, which can be replaced to use different immersion pipes 7 with different sized shower bases 8 if this is necessary.
  • a fastening nut 6 with a corresponding thread is provided in order to also effectively mount the dip tube 7 after inserting the reducer 5.
  • An adjusting tube 15 is rotatably arranged in the dip tube 7, this adjusting tube 15 also being rotatably connected to a cover cap 16.
  • the connection between the cover cap 16 and adjusting tube 15 is releasable, specifically via the locking piece 19, so that an upper stop can be dispensed with.
  • the lower stop 17 will be explained later, especially since it carries the simplified sealing element 18.
  • Fig. 2 shows an enlarged representation of the actual drain housing 2, here in particular the guide 20 is explained, which is to ensure a uniform pulling out of the adjustment tube 15.
  • the adjusting tube 15 is assigned two grooves 21, 23 arranged offset on the circumference and the immersion tube 7 correspondingly arranged corresponding guide pins 22, 24.
  • the grooves 21, 23 are embedded in the outer wall 25, so that the insertion of the adjusting tube 15 into the dip tube 7 is facilitated, as further below will be explained later.
  • the adjusting tube 15 has only one stop, namely the lower stop 17. It is realized by an extension 26 in that a groove 27 is formed which receives an O-ring 28 . This O-ring 28 rubs on the inner wall 31 of the dip tube 7, so that absolute tightness is guaranteed.
  • the adjustment tube 15 can be inserted from below into the dip tube 7 when the cover cap is removed or the cover cap 16 has not yet been attached, it being only necessary to ensure that the grooves 21, 23 match the guide pins 22, 24.
  • the cover cap 16 is then placed on the latching piece 19 and the upper stop is thus realized and the rotatability of the adjusting tube 15 is ensured.
  • Fig. 2 also illustrates that a dirt trap 29 is assigned to the overflow opening 30, which effectively prevents the ingress of dirt, in particular hair, into the adjusting tube 15. This dirt can not get into the wastewater cycle, but are easily disposed of separately.
  • Fig. 3 shows a further enlargement, which explains both the design of the guide 20 and additionally the connection of the individual parts of the drain housing 2 with each other.
  • the extension 26 is realized, which has the groove 27 with the O-ring 28.
  • This approach 26 serves at the same time as the lower stop 17, because the groove 21 ends accordingly here and is not pulled through to the lower edge 38.
  • the fastening nut 6 has a thread 34, which is designed to correspond to the thread of the reducer 5, so that after inserting the immersion tube 7 and the adjusting tube 15 with the aid of this fastening nut 6, it can be fixed on the bottom of the shower base 8. This bottom of the shower tray 8 is pressed onto the reducer 5 when the fastening nut 6 is tightened, a flat seal 33 being interposed. This makes it easy and convenient to create a tight connection in this area.
  • the reducer 5 has a further thread 37 on the outside, which is designed to correspond to the thread assigned to the drain housing 2 or the housing part 3. As a result, the reducer 5 is effectively fixed, specifically by clamping the further flat seal 32.
  • Fig. 4 shows a section through an adjusting tube 15 in the region of the guide pin 22, it being clear that a "right-angled" groove 21 is realized here. This means that the two flanks 40, 41 meet the groove base 42 at right angles, so that these flanks 40, 41 run parallel to the outer wall 44 of the guide pin 22. A corresponding friction is sufficient to lock the adjustment tube 15 in any position.
  • flanks 40, 41 run obliquely outwards from the groove base 42. 6, this is exactly the opposite, i. H. here the flanks 40, 41 run the other way round, so that there is a narrower opening.
  • the guide pin 22, which is not shown here, is given an adapted shape, which can be seen, for example, from FIG. 9.
  • a groove which has an arcuate groove base 43.
  • the flanks 40, 41 also run correspondingly beveled.
  • Such a groove 21 is particularly advantageous to use with a guide pin according to FIG. 11.
  • the groove 21 is V-shaped, so that a groove bottom 42 is not present in the sense. Rather, the two flanks 40, 41 converge in the groove base 42.
  • a guide pin 22 is shown here, which has a free end 45 equipped with bevels.
  • the free end 45 of a guide pin 22, 24 is equipped with an all-round projection 46, while a relief slot 47 introduced from below ensures that the two free ends 45 ', 45' 'now have a certain spring action.
  • the wedge tip 48 is pulled up to the shoulder 49 of the projection 46 or even shaped to extend beyond it.
  • the free end 45 of the guide pin 22, 24 has a plurality of spring feet 50, 51, 52 protruding obliquely outwards.
  • These spring feet which can be two, three or even four, press against due to their design Flanks 40, 41 of the groove 21, 23, so that the necessary friction can always be reliably generated. In a sense, this also results in wedge tips 48 'which are brought up to the shoulder 49'.
  • FIG. 11 shows an embodiment in which a guide ball 53 is inserted into the free end 45 of the guide pin 22, 24. She is in a ball bearing 54 embedded, which nevertheless allows the guide ball 53 to be “pushed out” by the spring 55 to a certain extent, so that the guide ball 53 is thus pressed into the groove base 43 or 42 via the spring force.
  • the friction that the locking of the adjusting tube 15 brings about can also be generated in a targeted manner in this way.
