Definitions

  • the invention relates to an adapter for fastening a push-up drain valve or the like in a drain fitting of a washbasin, according to the preamble of claim 1.
  • a plumbing push-up drain valve is a sink plug cap that connects to a spring and detent mechanism hidden in the downspout that allows the cap to be released by simply pressing down on the top of the to close and reopen the cap.
  • a push-up drain valve has a number of advantages over caps that simply consist of a rubber stopper, or those with a lever and rod for opening and closing from the outside.
  • push-up drain valves are typically offered as a pre-assembled kit that replaces the entire existing drain line from sink to siphon. Therefore, the acquisition costs and the installation effort are not inconsiderable, especially if you find out during an installation attempt that something does not fit.
  • a pre-assembled fitting is not always the right length to fit into an existing drain line from the sink to the siphon.
  • the invention is based on the object of creating an adapter that can be produced with particularly little effort and with which a push-up drain valve or the like can be attached to an existing drain fitting of a washbasin with very little installation effort.
  • the assembly of push-up drain valves or the like should be made possible regardless of the length of the drain line from the sink to the siphon.
  • the adapter comprises an outer section and a central section, which are preferably annular and are firmly connected to one another, preferably in one piece, while omitting water drainage space.
  • a simple transition piece can also be provided for push-up drain valves whose spring and latching mechanism does not reach up to the adapter or does not fit there.
  • figure 1 shows a commercially available push-up set 1 for wash basins, which has a push-up drain valve, which consists of a closure cap 2 and a spring and locking mechanism 3, and a downpipe 4 including a wash basin fastening ring 5.
  • the spring and detent mechanism 3 is inserted into the drop tube 4 from above and is supported thereby.
  • figure 2 shows an adapter 10 according to a first embodiment for fastening a push-up drain valve in a drain fitting of a washbasin, in the upper picture perspective obliquely from below and from above, in the middle on the left in a side view and on the right in a sectional view, and below in plan views from below and from above.
  • the adapter 10 is made of a piece of metal or plastic, with an annular outer portion 11 adapted to be mounted between a downspout depending vertically from a washbasin and a curved siphon connected thereto.
  • the adapter 10 of this embodiment has on its upper, i. H. the side facing a washbasin has an internal thread 12 in the outer section 11 that matches an external thread on the downpipe, and on its underside the adapter 10 has an external thread 13 that matches an internal thread in the siphon on the outer section 11.
  • the internal thread 12 and the external thread 13 are e.g. B. 11 ⁇ 4 inch.
  • a central section 14 which is designed to support the spring and detent mechanism of a push-up drain valve from below.
  • the central section 14 has an internally threaded hole 15 into which either a sufficiently long and appropriately designed end of the spring and latching mechanism or a suitable transition piece to the spring and latching mechanism can be screwed.
  • the internally threaded hole 15 has z. B. an M16 thread.
  • the outer section 11 and the central section 14 are connected in one piece while leaving water drainage space free.
  • the water drainage space is formed by two recesses 16 between the outer portion 11 and the central portion 14, the recesses 16 - seen in the direction of the central axis of the adapter 10 - are C-shaped. These recesses form through holes that allow the water to drain.
  • a corresponding water drainage space z. B. also be formed by a series of circularly arranged through holes in the adapter 10.
  • the rounding of the through-holes in both the C-shaped and circular configurations is advantageous in that it promotes the passage of hair or the like and reduces the risk of the adapter becoming clogged.
  • the C-shaped recesses 16 result from the fact that the outer section 11 and the central section 14 lie partly in one plane in their axial direction, that the outer section 11 has an inner diameter which is larger than the outer diameter of the central section 14, and that the outer portion 11 and the central portion 14 are integrally connected to each other by two radially extending spokes 17 where they lie in one plane.
  • FIG 2 The embodiment shown is intended for a drain fitting, the siphon of which is fastened to the downpipe with a union nut, with the adapter 10 being screwed in between.
  • Figure 3 Figure 12 illustrates how the adapter 10 is screwed to a downcomer end 6, after which a siphon end 7 is screwed to the bottom of the adapter 20 with a union nut 8, as shown in phantom.
  • figure 4 shows another adapter 20 according to a second embodiment for fastening a push-up drain valve in a drain fitting of a washbasin, in the upper picture perspective obliquely from below and from above, in the middle on the left in a side view and on the right in a sectional view, and below in top and bottom plan views.
  • the adapter 20 is made from a piece of metal or plastic with an annular outer portion 21 adapted to be mounted between a downspout depending vertically from a washbasin and a curved siphon connected thereto.
  • the outer portion 21 is a Circular ring with a - viewed in the radial direction - L-shaped radial cross-section, as can be seen in particular in the sectional view, so that it has two different outer diameters. With its smaller outer diameter, it fits a little into the siphon, but not with its larger outer diameter, which roughly corresponds to the outer diameter of the siphon.
  • a central section 24 which is adapted to support the spring and detent mechanism of a push-up drain valve from below.
  • the central section 24 has an internally threaded hole 25 into which either a correspondingly designed end of the spring and detent mechanism or a suitable transition piece to the spring and detent mechanism can be screwed.
  • the internally threaded hole 25 has z. B. an M16 thread.
  • the outer section 21 and the central section 24 are connected in one piece with the exception of water drainage space which is provided by two C-shaped recesses 26 between the outer section 21 and the central section 24 and two radially extending spokes 27 is formed, the recesses forming through holes for the drainage of water.
  • a corresponding water drainage space z. B. also be formed by a series of circularly arranged through holes in the adapter 20. The rounding of the through-holes in both the C-shaped and circular configurations is advantageous in that it promotes the passage of hair or the like and reduces the risk of the adapter becoming clogged.
  • FIG. 4 The embodiment shown is intended for a drain fitting, the siphon of which is fastened to the downpipe with a union nut, with the adapter 20 being pushed in between.
  • figure 5 1 shows how the adapter 20 is inserted into a downpipe end 6, after which a siphon end 7 is screwed to the downpipe end 6 with a union nut 8, as shown in dashed lines.
  • the adapter 20 can also simply be pushed into the downpipe end 6 or siphon end 7 from below and attached to it be positively fixed, as in Figure 5A shown.
  • the outer section 21 of the adapter 20 is in the assembled state in the upper position and not in the lower one as in FIG figure 5 shown.
  • the adapter 20 is circular-cylindrical and does not have the protruding section 21 of the adapter of the previous embodiments.
  • the lateral surface of the adapter 20 thus runs along a large number of straight lines and offers sufficient space to accommodate a sealing ring or an O-ring 39 in a circumferential depression in the lateral surface of the adapter 20 .
  • the sealing ring or the O-ring 39 serves to positively fix the adapter 20 in the downpipe end 6 or siphon end 7 or generally in a pipe.
  • the symmetrical design of the adapter 20 of this alternative according to the third exemplary embodiment is particularly advantageous since the adapter 20 can easily be pushed into a pipe from below or above. Sliding it into the washbasin from above is particularly advantageous, as the installation effort is minimized.
  • the sealing ring or O-ring 39 is formed from a suitable material such as rubber, elastomer, polymer or mixtures thereof. Although only a single sealing ring or O-ring 39 is shown in the specific illustration, it is conceivable according to the invention to equip the adapter 20 with two or more sealing rings or O-rings 39 .
  • the alternative adapter of the embodiment of Figure 5A can be used advantageously in all embodiments of the invention, in particular if a non-positive connection is to be made with a pipe.
  • a in 6 shown embodiment corresponds to that of 4 and is shown in corresponding views, except that there is an additional transition piece 30 to the push-up drain valve.
  • the transition piece 30 with the embodiment of figures 2 and 3 is used.
  • the outer section 21 of the adapter 20 is in the upper position and is suitable for assembly as in FIG Figure 5A shown suitable.
  • the transition piece 30 is a substantially cylindrical elongated member, one end of which is provided with a male thread fitting into the female threaded hole 25 of the central portion 24 and the other end is formed to be fixed to a lower end of a spring and detent mechanism of a push-up -Drain valve to be connected.
  • the external thread of the transition piece 30 is designed to match the screw connection with the internally threaded hole 15 .
  • the transition piece 30 can preferably with one in the Figures 1 to 6 thread not shown be equipped at its upper end.
  • the thread designated by the reference numeral 31 is in the figures 7 and 9 shown.
  • the transition piece 30 can also include the spring and latching mechanism of the push-up drain valve, so that in this case other parts, such as the one shown in FIG EP1580337 B1 or the one from the EP2921594 B1 known drain plug can be attached to the transition piece 30.
  • other parts such as the one shown in FIG EP1580337 B1 or the one from the EP2921594 B1 known drain plug can be attached to the transition piece 30.
  • known parts can also take over the function of push-up drain valves.
  • these other parts, such as from EP1580337 B1 or the one from the EP2921594 B1 known drain plugs can be attached to the transition piece 30 without the presence of the spring and detent mechanism on the transition piece.
  • the 7 shows the transition piece 30 with the thread 31 and a matching drain plug 32, wherein preferably the drain plug 32 with a removable cover 34 is equipped.
  • the removable cover 34 allows, in a known manner, the introduction of water-soluble substances inside the drain plug 32, such as deodorizing or disinfecting substances.
  • the drain plug 32 is formed with a matching thread 33 so that it can be connected to the thread 31 of the transition piece 30 .
