EP0309397A1 - Water supply connection arrangement for sanitary installations - Google Patents

Abstract

A concealed connection housing (1) has continuous channels with connecting-branch pairs (12, 12', 13, 13') for cold and warm water. Two further connecting branches (306, 307) serve to conduct mixing water, for example, to a bath inlet and to a shower. A fitting housing (21) for receiving a mixing fitting is fixed on the connection housing (1) so as to be rotatable about its longitudinal axis and lockable. A distributor (4) with coaxial annular channels (328, 329, 330) is inserted between fitting housing (21) and connection housing (1). The distributor (4) is sealed off from the fitting housing (21) and the connection housing (1) by concentric sealing rings (338) of different diameter. As a result, the cold-and warm-water supply pipes can be laid at any desired angles. By exchanging the inner pipe (326) of the distributor (4) for another connection part, it is additionally possible to change over cold and warm water, so that even if the piping is wrongly installed warm water is supplied to the fitting on the left and cold water on the right. <IMAGE>

Description

The present invention relates to a sanitary water connection arrangement according to the preamble of independent patent claim 1.

In conventional sanitary facilities, cold and hot water pipes are installed in parallel in a concealed installation. The supply lines to the fittings are standardized so that the hot water connection is always on the left and the cold water connection is always on the right. In addition, the line openings must either be arranged approximately exactly horizontally next to one another or in certain cases vertically one below the other. Deviations of a few millimeters can be compensated for by using eccentric connecting pieces. This assembly meant a lot of work for the sanitary fitter, because after laying the pipes in slots in the walls, bricklayers, plasterers or other craftsmen have to continue working, and therefore often make changes to the previously precisely aligned pipes. But also in pipe-in-pipe systems, where the supply lines are made of plastic, relatively large tolerances must be expected.

This conventional assembly is opposed to the so-called chaotic assembly, in which it is not possible, for example due to structural reasons, to supply the supply lines for hot and cold water in an orderly manner, or in old buildings in which the connections have to be arranged in an orderly manner due to the old separate taps. Therefore, an adjustment or even change should be possible.

Devices for the interchangeable installation of sanitary mixer taps have long been known. One such is shown in AT Patent No. 177,382. Water pipes are connected to a connection piece, which either find their end in the connection piece or are passed through this. Branch lines branch off perpendicularly to these water lines and these end in a surface parallel to the water lines. The valve is connected to this connector. A disadvantage of such an arrangement is that the water pipes have to be arranged exactly horizontally because the fitting is rigidly adjusted to this basic assembly as a result of the connecting piece.

This disadvantage is eliminated in the embodiment according to DE Patent No. 879 678 in that the fitting is screwed into a central connection on the connection piece with the thread of a central connecting pipe. The outer lead is sealed with a wall rosette, which in turn is attached to an external thread of an outer coaxial tube of the connector is screwed. Inaccurate installation can be compensated for by changing the screw-in depth accordingly and thus adjusting the mutual position of the fitting and the connecting piece.

In a later publication, DE laid-open specification 18 11 936, only the housing of the fitting is screwed into the housing of the connecting piece, while an inner tube is slidably inserted into a central connecting piece. Of course, this means that the position is largely freely adjustable and the wall distance can also be corrected.

The connector itself is designed only for an end connection of the two water pipes and is not intended for the passage of two water pipes. However, this connection piece shows a central connection which communicates with the one water line and a ring channel which leads around it and which communicates with the other water line. This ensures that the valve is in position.

A disadvantage of the proposed solution is that the position of the fitting can only be corrected via the thread, so that only a very specific type of fitting can be used. The correction of the thickness of the plaster can also only be corrected by screwing it in more or less deeply, which is difficult with such diameters of the screw parts. Furthermore, no filters can be arranged with such an arrangement or install a non-return valve or other additional elements.

It is therefore an object of the invention to provide a sanitary water connection arrangement which is inexpensive to manufacture and which enables interchangeable fastening for different fittings, in which different thicknesses of the plaster or wall coverings can also be compensated for, and above all in the case of the conventional arrangement of the Lines expensive, but necessary in the case of chaotic installation, changeover and direction of rotation compensating means can be omitted

According to the invention, this is achieved by the features in the characterizing part of patent claim 1.

1 to 21, the same parts are identified by the same reference numerals.

The arrangement according to FIG. 1 is for conventional assembly, ie in which the tubes are arranged exactly parallel and horizontally or vertically in slots in the wall. The connection housing 1 with the connection part 10 and the cylindrical base part 11 can be clearly seen. 2 shows the top view of this connection housing 1.

In the connecting part 10, two pairs of connecting pieces 12, 12 'and 13, 13' are arranged parallel to each other. The connecting piece 12, 12 'on the one hand and 13, 13' on the other hand form two separate pipe connections. A branch line 14, 15 is branched off from each of these pipe connections, the axes of which are arranged perpendicular to the plane of the pipe connection and parallel to the axis of the cylindrical base part 11.

Any known single or multi-lever mixer can be used as a fitting. For this reason, only the two ceramic control disks 28, 29 have been shown, of which the control disk 28 is connected in a rotationally and displaceably fixed manner with a connecting piece 27. The control disk 28 lies on a stationary disk 29 and, with its movement, releases the openings 29a, 29b in order to guide a certain amount of water with a desired mixing temperature to an outlet opening 29c located behind the cutting plane.

The supply of cold and hot water thus takes place via a matching element 22 through the openings 29a, 29b in the fixed disk. For the connection between the branch lines 14, 15 and the openings 29a, 29b nipples 3, 3 'are provided, which are screwed into the base part 11 of the connection housing 1, as shown in the right half of Fig. 1 shown in section.

For the rigid connection between the valve body 21 and the base part 11, two different embodiments are shown in FIG. 1. In the left half of FIG. 1, a union nut 16a is captively held on the base part 11 by means of a threaded ring 17. At its other end, the union nut 16a carries a thread with which it is screwed onto the housing of the fitting 2.

The stop for the screw-in depth of the union nut 16a is given by the length of the nipples 3, 3 ', which engage with their cylindrical pins 32 in an insertion opening and abut there.

The nipples 3, 3 'have on the remaining part of their length an external thread which is divided into four sections 33a, 33b, 33c, 33d. Between each two sections there is a groove 34a, 34b and 35. The two grooves 34a, 34b serve to receive a sealing ring 36 and the groove 35 is a mark for the specific shortening of the nipple when the connection housing 1 is inserted a little deep into the wall is. Thus, the thickness of the wall covering or covering can vary within wide limits and the armature 2 is nevertheless always exactly the same distance from the wall surface.

According to CH-A-381 170, nipples for connecting a flush-mounted connecting piece to a fitting have become known. Only the nipples on the acquaintance have a bead with which a support plate is pulled up to the wall. The attachment of the Valve is made using a union nut on the support plate. As a result, the nipples are permanently loaded and could therefore change structurally. In contrast, the nipples according to the present invention only serve to adjust the fitting to the distance. The frictional connection takes place between the housing of the valve and the connection housing.

The connection housing 1 can be encased with a plastic protective sleeve 18, which can be designed in a known manner as a cap in order to keep the space necessary for the attachment of the valve in order to be cut off after pouring in.

The second embodiment for the union nut 16b is shown on the right in FIG. 1. The only difference from the first embodiment described above is that it is not held with a threaded ring on the connection housing 1, but with a second thread. If the upper thread 16c has a smaller pitch than the lower thread 16d, e.g. 2 mm and 1.5 mm, the fitting 2 can be brought to a stop between the sleeves 30 and the pin 32, as long as the union nut 16b is still screwed to it.

Fig. 3 shows in principle the same arrangement as Fig. 1 and 2. Because it is a requirement in some countries to install non-return valves in the fittings, they can be used with conventional ones Installation can only be installed if the valve is extended accordingly. Backflow preventers are well known devices. The drawing was therefore omitted and only the cavities 42, 43 required for this purpose were drawn in the two separately guided feed lines 40, 41.

To cope with the problems that arise with a disordered installation, a so-called battery piece was provided in the valve connection element known from EP-B-119 960, to which the disordered supply lines are arranged offset in the axial direction with respect to one another. The fitting engages in the hole in the battery piece. If two parallel circumferential grooves, each communicating with an inflow line, are provided in the fitting or in the battery piece, the fitting can be used in any rotational position with respect to the battery piece. However, if the hot and cold water supply are interchanged, the part of the fitting that dips into the hole must be separated from the fitting in order to make it possible to change the plug. However, the plug-in part with its axial bores is very expensive to manufacture, so that it can hardly arouse a great deal of interest in new installation technology.

The present invention solves these problems with reference to the embodiments according to FIGS. 4 and 5, in that the nipples 3, 3 'as shown in FIGS. 1 and 2 are screwed into the base part 11, but subsequently there is a distributor 4 is provided, which can be used in the extended housing 21 '.

This distributor 4 is thus provided with sockets 30, 30 'for the nipples 3, 3', which also form the stops for the insertion depth. From the outside, the distributor 4 consists of a base cylinder 53 and an insert cylinder 54 for the connection to the fitting 2, which will be discussed later.

The two cylinders 53, 54 differ in diameter, the base cylinder 53 having a substantially larger diameter than the insertion cylinder 54.

The passages within the distributor 4 are simple axial bores, of which a passage 59 opens into the shoulder surface 55, as the top surface of the base cylinder 53, as an opening 59b and is formed as an axially parallel bore between the corresponding plug-in socket 30, 30 'and this opening, and the other passage 58 is composed of two bores 58a, 58b, of which the one in the base part 53 is eccentric but axially parallel and the one in the insertion cylinder 54 is coaxial and at least partially overlaps and forms a free passage.

By offsetting the inlet openings 29a, 29b of the fitting 2, as can be seen from FIG. 1, using practically the same means axis distance are arranged, an adjustment is still necessary for the water supply. This can be accomplished in a very simple manner by a connection plate 22 in the housing 21 'of the fitting 2.

By a distance between the shoulder surface 55 and a connecting piece 60, a channel 62 is formed around the insertion cylinder 54, so that the fitting 2 is connected to the two connecting pipes 12, 13 of the connecting part 10 in every rotational position.

If cold and hot water connections are reversed in a disordered installation, this can be corrected by simply repositioning the distributor 50 on the two nipples 3, 3 '.

The attachment of the housing 21 of the fitting to the base part 11 of the connection housing can be provided in the same way as in the exemplary embodiment according to FIG. 1 described above.

In the exemplary embodiment according to FIG. 4, no backflow preventers are provided. However, these can be installed in the simplest manner according to the exemplary embodiment according to FIG. 5 in the distributor 4, which is lengthened by the additional length of the two cavities 58c, 59c. Likewise, the housing 21 of the fitting 2 must of course also be extended by the same amount. The other parts such as connection housing 1, nipple 3, 3 'and fitting 2 are the same as in the exemplary embodiments described above.

Another advantage of this invention is that instead of the nipples 3, 3 'plugs can be screwed in to press off the lines or ventilation valves, so that the entire pre-installation can be carried out.

The connection housing 1 with the connection part 10 and a cylindrical housing part 11 can be seen in the arrangement according to FIG. 6. At the connecting part 10 again two pairs of connecting pieces 12, 12 'and 13, 13' are arranged in parallel to each other.

Above the pair 12, 12 ', an eccentric, axially parallel bore is arranged which penetrates into the connecting piece connection and thus forms a stub 15. In the housing part 11 there is a central bore 117 which has a radius which corresponds to the distance between the axis of the housing part 11 and the outermost peripheral point of the stub 15, or as shown in FIG. 6, is somewhat larger than this distance. From the bottom 119 of this central bore 117, a blind hole 14 is drilled between the two pairs of connecting pieces 12, 12 '13, 13' which breaks through the wall of the second pair of connecting pieces 13, 13 'and thus generates a radial branch line.

A cylindrical recess 116 is formed centrally in the bottom 119 in the central bore 117 and is located above the blind hole 114 and serves as a seat for a pipe section 105.

This separates a central line with an annular channel around it.

There is also a central bore 122 in the housing 21 of the fitting 2, which has the same diameter as the central bore 117 in the connection housing 1. Through the pipe piece 105 mentioned, which engages with its free end in a bore 123 in the housing 21, it is also in the housing 21 an annular channel is separated, from which a feed bore 125 leads to the connection part of the fitting.

Behind the hole 123 there is a collecting cavity 124 in the connection part of the fitting, which creates the connection to the second feed hole 126. The line 127 for the connection for mixed water is shown between the feed bores 125, 126 and above the collecting cavity 124.

A union nut 129 is caught with a threaded ring 118 on the connection housing 1 and is screwed onto a thread 128 on the housing 21, so that the housing 21 and the connection housing 1 can be rigidly connected to one another.

With such an arrangement, the fitting can be corrected for precise alignment even with inaccurately laid conduit pipes. However, swapping hot and cold water pipes cannot be reversed. For this purpose, an additional element according to FIG. 7 is used instead of the tube piece 105 in Fig. 6 required. This distributor 4 is inserted into the central bore 117 in the connection housing 1 and in the central bore 122 in the housing 21 of the fitting 2.

With two opposing nozzles 140, 141, the distributor 4 engages in the cylindrical recess 116 in the connection part 10 of the connection housing 1 on the one hand and in the bore 123 in the housing 21 on the other hand. A radial flange 142 seals against the wall of the central bore 122 of the housing 21 and divides the annular channel in FIG. 6 into an annular channel 143 in the connection housing 1 and an annular channel 144 in the housing 21.

The axially parallel lines 145, 146 and radial openings 147, 148 connect the two ring channels 143, 144 to the respective connection piece 140, 141 located at the opposite end of the distributor 4. The connection paths according to FIG. 6 are thus interchanged.

A similar such additional element is known from US Pat. No. 3,823,737. This is intended for wall connections with fittings arranged on both sides of the wall in order to swap cold and hot water pipes on one side of the wall.

Although constructed similarly, a direct adoption of the inventive concept is not possible because the distributor 4 according to the invention are installed in a given housing arrangement In order to replace a simple piece of pipe 105 (FIG. 6), hot and cold water pipes have to be exchanged for chaotic installation.

Since the two parts, the pipe section 105 and the distributor 4, can be produced very cheaply, these two parts could be supplied with each fitting, so that the installer has the choice of exchanging the supply lines in the housing 21. In both cases, the fitting 2 can be rotated relative to the connection housing 1 in order to compensate for an inaccurate installation of the line pipes.

Since a union nut 129 caught on the connection housing must naturally also be provided here for fastening the fitting 2 to the connection housing 1 in order to hold the two parts, the pipe section 105 or the distributor 4 interchangeably, it is not possible to adjust the distance from the wall surface without additional means be made possible.

Such an arrangement for setting both conventional precise installation and chaotic installation with an adjustment of the wall distance is shown in FIG. 8. Although only the version with a distributor is shown here, this distributor could of course also be replaced by a pipe section according to FIG. 6. The changes compared to the embodiments according to FIGS. 6 and 7 thus relate to an extension of the cylindrical recess 116 in 6 and 7, an extension of the lower connection piece of the distributor 4 and an extension of the wall of the housing 21 which engages in the central bore 117 in the connection housing 1. With such an arrangement, if the distributor 4 with its upper connection piece is rigid in the bore 123 an axial displacement of the fitting 2 relative to the connection housing 1 is used.

In order to set the wall distance precisely, spacer rings 132, 133 are provided between a rib 130 on the housing 21 and a radial flange 131 on the connection housing 1. On the rib 130 there is a ring 134 with holes 135 for receiving a fastening screw 136 which can be screwed into threaded holes 137 in the flange 131.

In the connection housing 1 according to FIGS. 9 and 10, a connection part 10 is again provided with four pipe sockets 12, 12 '13, 13', which are arranged in pairs parallel to each other in a row. Above these connecting pieces there is a cylindrical base part 11 with an axial main bore 218. The one connecting piece pair 13, 13 'is open with a first stub 15 to the main bore 218. The other pair of connecting pieces 12, 12 'is cut with a second stub 14, so that there is a passage 19 in the radial direction into the main bore 218.

A cylindrical distributor 4 is rotatably inserted into the main bore 218. This distributor 4 has a pierced pin 221, which is sealingly inserted into the second stub 14. A surface 223 set back with respect to the end edge 222 of the pin 221 forms together with the base 217 of the main bore 218 an annular channel 224 leading around the pin 221.

An axially parallel first passage 225 in the distributor 4 communicates with the first stub 15 in the connecting part 11 and one of these stub 15 diametrically opposite second passage 226 communicates with a coaxial bore 227 in the pin 221 via a connection 226 '. An axial bore 228 is located centrally between the mouths of the passages 225, 226.

The distributor 4 is held in the housing part 11 by means of a holding plate 229. This holding plate 229 in turn is rigidly held by means of three screws 230 which are screwed into peripheral eyes 216 on the housing part 11. In addition to the two openings 231, 232 aligned with the passages 225, 226, it also has a central threaded bore 233 aligned with the bore 228.

Of the valve 2, only the lower part of the housing 21 is drawn, in which the supply lines 241, 242 and discharge line 243 are provided for adaptation to the respective type of valve. An axially central bore 244 serves to receive a cylindrical head 245 of a stud screw 246 screwed into the threaded bore 233.

In the head 245 of the stud screw 246 there is a square, diametrically arranged opening 247 into which an eccentric part 248 of an eccentric pin 249 engages. This eccentric pin 249 can be used through a radial bore 250 in the valve body 2 '. To connect the passages 225, 226 and the feed lines 241, 242, two nipples 3, 3 'are provided, which are rigidly held, for example, in the valve housing 21, such as by a press fit or by soldering or the like. In the distributor 4, the two nipples 3 , 3 'slidably inserted by means of edged seals.

With this arrangement, a fitting 2 can be disassembled from the connection housing 1 by simply loosening the eccentric pin 249 and, if the screw-in depth of the bolt screw 246 has not been changed, it can be replaced and fastened after any repairs have been carried out. The water-carrying parts, namely the distributor 4 and the nipples 3, 3 ', are not under load. The power flow passes from the stud screw 246 to the holding plate 229 and via the screws 230 into the connection housing 1.

Two or one or more spacer rings 234, 235, of which one spacer ring 234 is screwed onto the valve housing 21 of the valve 2, are used for the basic setting of the screw-in depth of the bolt screw 246 into the holding plate 229.

While the above-described embodiments for fittings with a mixed water line for direct outlet are provided from the fitting, the following exemplary embodiments according to FIGS. 12 to 21 have mixed water pipes which lead to a shower and / or a bath water inlet via the plastered connection housing.

In DE-A-35 19 652 an arrangement with an additional connection piece for mixed water is provided, but four valves are arranged in the connection housing, two of which communicate with a bore emerging on the one hand and with the continuous cold or hot water channel on the other . The two holes are aligned with other holes in a distributor on which the mixing valve is placed. Cold or warm water can be supplied to the two bores, so that a wrong connection to the connecting piece can be corrected. This is particularly useful if fittings should be connected to the same pipes laid in a wall on both sides of the wall. So that the fitting can be installed correctly, it is necessary with this known arrangement that the cold and hot water pipes run horizontally. This makes complex installations necessary.

A further embodiment for a connection arrangement for a mixing valve is shown in section in FIG. 12. It comprises a flush-mounted connection housing 1 with a cold water line and a hot water line, each with a connection piece 12, 12 ', 13, 13' (Fig. 14), so that the connection housing 1 can be used in continuous lines can. Two mixed water connection sockets 306, 307 are arranged transversely to the connection pipe pairs 12, 12 ', 13, 13'. At right angles to the level of the connecting piece pairs 12, 12 ', 13, 13', coaxial, cylindrical bores 308 are machined in the connection housing. A fitting housing 21 is fastened on the connection housing 1 coaxially to the bores 308 by means of screws 323. The screw head presses a collar 319 of the valve housing 21 against the connection housing 1 and is supported on the outside by a ring 320. As a result, the valve housing 21 can be rotated as desired about its axis relative to the connection housing 1 and fixed by the screws 323. At the opposite end, the valve housing 21 has a threaded bore 322 with a flat base 323 for inserting a mixing valve, not shown. Three axially parallel bores 316, 317, 318 for hot water, cold water and mixed water open into the base area 323 and are aligned with corresponding bores in the mixer fitting.

Between the valve housing 21 and the connection housing 1, a distributor 4 is inserted, which in the exemplary embodiment according to FIG. 12 consists of two coaxial tubes 326, 327. These enclose, together with the outermost bore 308, three coaxial ring channels 328, 329, 330. These ring channels connect passages 333, 334 or stub lines 14, 15 of the connection housing 1 with passages 335, 336, 337 of the fitting housing 21, each with one of the holes 316, 317, 318 are connected. The passages 333, 334 and stub lines 14, 15 open into the ko at different radial distances axial bores 308 and connect the three ring channels 328, 329, 330 to the connection piece pairs 12, 12 ', 13, 13', the outermost ring channel 330 being connected to both mixed water connection pieces 306, 307. The distributor 4 is sealed on both sides by two concentric O-rings 338 of different diameters from the fitting housing 21 or the connection housing 1.

If the cold and hot water pipes have been exchanged during the installation of the connection housing 1, the inner pipe 326 of the distributor 4 is exchanged for a distributor 4, as shown in FIG. 13. The distributor 4 seals with a flange 344 and an O-ring 345 in the pipe 327. The two passages 328, 329 here connect the passages 331 and 336 or 332 and 335 to one another, so that cold and hot water are mixed up with the mixer fitting compared to the variant according to FIG.

The embodiment according to FIG. 15 differs from that according to FIG. 12 in that an exchange valve 352 is additionally installed in the connection housing 1. With this valve 352, the mixed water can optionally be supplied via one of the two outlets 353, 354 to one of the two mixed water connections 306, 307, for example for connecting a bath inlet or a shower. Otherwise, this embodiment corresponds to that according to FIG. 12.

In the embodiment according to FIGS. 16 and 17, the shuttle valve 352 is arranged in the valve housing 21. For this purpose, the distributor 4 has a further coaxial tube 357, which separates the two outlets 353, 354 of the valve 352 from one another, so that they are each connected to one of the mixed water connection stubs 306, 307. For this purpose, the two channels 333, 334 of the connection housing 1 open at different radial distances into one of the coaxial bores 308. Otherwise, the embodiment according to FIGS. 16 and 17 corresponds to that according to FIG. 15.

A further variant of the embodiment according to FIGS. 16 and 17 is shown in FIG. 18, in which the valve housing 21 is both rotatable and continuously axially displaceable and lockable relative to the connection housing 1. For this purpose, the valve housing 21 has a tubular extension 360 which is longitudinally displaceable and rotatable in the outermost bore 308 of the connection housing 1 and is sealed with a further O-ring 361. A slotted ring 362, which is tapered on both sides and is tapered on both sides, is used for clamping. This is inserted into corresponding conical surfaces of a flange 363 of the connection housing 1 and a ring 364. The ring 364 is pulled by the screws 323 against the flange 363 and thereby presses the ring 362 radially against the shoulder 360.
