Definitions

  • Such a sanitary fitting is shown in DE-A-39 07 204, in particular in FIG. 3.
  • This is a bathtub spout, which can be mounted on a mounting plate serving as a bracket in a recess on the side of a bathtub.
  • the adjustment of the distance between the lower end face of the outer fitting part and the mounting plate takes place in such a way that the inner fitting part can be displaced in the axial direction relative to the mounting plate and can be fixed in different axial positions.
  • this presupposes that the fastening means, which serve to axially fix the inner part of the fitting on the mounting plate, are always accessible.
  • variable distance between the lower end face of the valve outer part and the bracket should serve to compensate for different thicknesses of a tiling to be applied to the holder (for wall installation: different thicknesses of the plaster or the like).
  • the inner part of the fitting is first attached to the bracket, for example to a mounting plate. Another craftsman then applies the tiling over the mounting plate. Finally, in the final assembly, the outer part of the fitting is plugged onto the outwardly protruding area of the inner part of the fitting. It is only at this point in time that the exact target position of the lower end face of the outer fitting part is known.
  • the object of the present invention is to design a sanitary fitting of the type mentioned in such a way that, on the one hand, the required adjustment of the fitting outer part relative to the holder can take place without the parts covered by the holder having to be accessible, and on the other hand the fitting outer part robust is secured against rotation.
  • the first part of the above-described task namely the subsequent adjustability of the position of the valve outer part, is achieved according to the invention by the screw bushing which extends through the holder and can be gripped and rotated by a tool at its outer end. If the outer part of the fitting were to be placed directly on this screw bushing, its angular fixation on the screw bushing would have to take place by means of a screw or the like which rests against an outer surface of the screw bushing. However, such a fixation would not be sufficiently stable. For this reason, the coupling part is provided according to the invention for solving the second partial task described above.
  • the coupling part with its non-circular contours creates a positive connection between the inner part of the fitting and the outer part of the fitting, which very reliably and stably prevents the rotation of the outer part of the fitting relative to the inner part of the fitting and thus ultimately against the holder.
  • the coupling part follows the axial movement of the screw bushing in such a way that the fitting outer part fastened on the coupling part can have different distances from the inner part of the fitting and thus also from the holder in the desired manner.
  • the screw bushing should have an engagement surface at its outer end for a tool suitable for screwing.
  • the water path leads to the valve outer part through the interior of the screw bushing. In this way, a separate channel, which would need its own space, through the valve interior part is not necessary.
  • sanitary fittings of the type of interest here have a changeover device which Water flow either directed to the outer part of the fitting or to another water consumer and comprises a double valve cone which interacts with two valve seats and can be moved via an actuating rod.
  • the actuating rod is passed axially through the inside of the screw bushing. The reason for this measure is again that no special channel with its own space requirement for the actuating rod in the inner part of the valve is then required.
  • One of the two valve seats, with which the double valve cone of the changeover device interacts, can be formed on the inner end face of an insert bush which is fixed in the interior part of the fitting, the insert bush having an internal thread which interacts with an external thread of the screw bushing.
  • a particularly preferred embodiment of the invention is characterized in that the coupling part is connected to the screw bush by a snap ring which lies in an annular space which is partly formed by a groove in the coupling part and partly by a groove in the screw bush.
  • the snap ring represents a positive entrainment connection between the screw bushing and the coupling part.
  • the screw bushing can move relative to the snap ring without the coupling part being taken along.
  • the first non-circular region of the coupling part can be formed on an apron which is molded onto the coupling part and overlaps the outer contour of the inner part of the fitting.
  • a tub spout 1 is shown, which - unless otherwise described below - is mounted in a similar manner as in DE-OS 39 07 204 mentioned above on the edge of a bathtub in an installation niche provided there.
  • the bathtub spout 1 is composed of two main components:
  • a fitting inner part 3 is mounted on a horizontal mounting plate 2, which is fastened in the recess in a suitable manner.
  • An outer fitting 4 is attached to this, as will be explained in more detail.
  • the distance between the lower end face of the outer fitting part 4 and the mounting plate 2 can be varied in a manner described in more detail below in order to be able to compensate for different thicknesses of the tiles 36 used for cladding the mounting plate 2.
  • tub inlet 1 the structure of the tub inlet 1 shown in the drawing is as follows:
  • the valve inner part 3 comprises a lateral connection piece 5, through which the water is supplied.
  • the water reaches a changeover device 7, which comprises a double valve plate 8 and an actuating rod 9.
  • the double valve plate 8 can optionally cooperate with an upper valve seat 10 and a lower valve seat 11.
  • the double valve plate 8 is located on the lower valve seat 11, the water path to the axial shower connection piece 12 pointing downward is blocked. No water can thus escape from a hand shower, which is arranged next to the bath inlet 1, but is not shown in the drawing and is connected to the shower connecting piece 12 via a hose. Instead, the water entering via the connecting piece 5 flows upward through an axial bore 13 of a screw bushing 23 into an outlet space 14 of the outer fitting part 4 and from there to the outlet mouthpiece of the tub inlet 1, which is no longer shown in the drawing.
  • the double valve disc 8 is in contact with the upper valve seat 10, which is formed by the lower end face of the insert bush 15, then the last-described water path to the outlet mouthpiece of the tub outlet 1 is blocked; the water path to the hand shower via the shower connector 12 is released.
  • the movement of the double valve plate 8 between the two valve seats 10 and 11 is carried out manually by means of the actuating rod 7, which is guided coaxially through the axial bore 13 of the insert bush 15, through the outlet space 14 of the outer part 4 of the fitting and through its wall.
  • a handle (not shown) is placed on the outer end of the actuating rod 9.
  • the insert bushing 15 has a collar 16 with an enlarged diameter with an external thread 17.
  • the external thread 17 of the insert bushing 15 interacts with a corresponding internal thread 18 on the inner contour of the fitting inner part 3, which is complementary to the insert bushing 15.
  • An O-ring 19 in the region of the lower end of the insert bush 15 lies in a groove 20 of the inner part of the fitting 3 and prevents water from entering the gap between the insert bushing 15 and the valve inner part 3.
  • the insert bushing 15 is provided with an internal thread 21 in the upper half.
  • This internal thread 21 interacts with a corresponding external thread 22 of a screw bushing 23 which is mounted coaxially inside the insert bushing 15, axially screwable relative to the latter.
  • the outer contour of the screw bushing 23 can be divided into three areas, the diameter of which decreases from top to bottom:
  • the uppermost region 24 has a smooth, cylindrical outer surface. It is followed at the bottom by the thread region 22 already mentioned, which in turn merges at the lower end of the screw bushing 23 into a guide region 25 with a smooth cylindrical outer surface.
  • the outer contour of the inner part 3 of the fittings is at least in the region of the passage through the mounting plate 2 out of round, that is to say not rotationally symmetrical, preferably of multiple surfaces.
  • a corresponding contour also has the mounting opening 26 of the mounting plate 2, through which the inner fitting part 3 is pushed.
  • the arrangement is such that the fitting inner part 3 cannot be rotated relative to the mounting plate 2 due to a positive fit.
  • the inner fixture part 3 is axially fixed to the mounting plate 2 by means of a screw 27.
  • a coupling part 28 is pushed onto the uppermost region 24 of the screw bushing 23 in such a way that the screw bushing 23 can rotate with respect to the coupling part 28, but the coupling part 28 takes along during its axial movement.
  • the screw bush 23 is on its outer surface with a groove 29 and the coupling part 28 on its inner surface with a groove 30. Both grooves 29, 30 complement each other to form an annular space in which a snap ring 31 lies.
  • the snap ring 31 obviously transmits the axial movement, but not the rotary movement of the screw bushing 23 to the coupling part 28.
  • a downward facing apron 32 is formed on the coupling part 28.
  • the inner contour of the apron 32 is non-circular, that is to say not rotationally symmetrical, and engages over a region of the inner part of the fitting 3 provided with a complementary outer contour, that is also out of round. This ensures that the coupling part 28 does not twist with respect to the inner part 3 of the fitting can.
  • the screw bushing 23 is sealed against the insert bushing 15 by an O-ring 33 and against the coupling part 28 by an O-ring 34.
  • the coupling part 28 in turn is also provided with an out-of-round, in particular therefore not rotationally symmetrical, outer contour 38.
  • the valve outer part 4 with a connection opening 35 is plugged onto this outer contour 38, which has a complementary, non-circular inner contour. In this way it is ensured that the valve outer part 4 cannot rotate with respect to the coupling part 28 and thus with respect to the valve inner part 3 and the mounting plate 2.
  • the screw 6 serves to axially secure the valve outer part 4 on the coupling part 28.
  • the top of the mounting plate 2 is clad by the tiles 36.
  • the thickness of these tiles can vary within certain limits.
  • the installation of the bath spout 1 is carried out in such a way that first the interior of the fitting 3 on the Mounting plate 2 is fixed by means of the screw 27 and the mounting plate 2 is then fastened in the egg niche next to the bathtub. The tiler then attaches the tiling 36 over the mounting plate 2, which is then no longer removable.
  • the fitting outer part 4 In the "final assembly", the fitting outer part 4 must then be plugged in, taking into account different thicknesses of the tiles 36, but the parts of the fitting located below the tiles 36 are no longer accessible to adapt the mounting position.
