Abstract

The fitting has a polygonal pipe body, having a threaded shaft (5), the diameter of which is smaller than the smallest pipe-body cross-section. A disc (9), a pressure-applying plate (8) and a rubber ring (7) are located between the pipe body (3) and a rosette (6). A neater finish than is possible with production-related rosettes, due to push-in differences between the outer dimensions of the polygonal pipe bodies and the opening in the rosette, is achieved in this manner. <IMAGE>

Description

(54) SANITARY WATER FITTING (71) We, IDEAL STANDARD GmbH, a German company of Euskirchener Strasse 80, 53 Bonn 1, Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to a sanitary water fitting, particularly although not exclusively an inlet to be fixed on a wall for use with sanitary installations or articles such as washbasins, baths or the like, consisting of a body which has an angular cross-section at least at its wall end, the wall end having a threaded shank with a smaller diameter than the width and depth of the cross-section of the body and which carries an escutcheon plate, sometimes referred to as a rosette or a facia disc.

Inlets for wash basins, baths or the like generally consist of tubular bodies of circular cross-section, or of the tubular bodies which have an angular cross-section over the most part of their length, whilst their wall ends are circular in cross-section. A neat seal to the wall is produced with an inlet of this type by means of a conventional push-on escutcheon plate. In practical terms, push-on escutcheon plates are suitable for inlets which are of angular crosssection at their wall ends or throughout their length, since because of tolerance differences in the external measurements of the inlets which arise in manufacture, it cannot be guaranteed that push-on escutcheon plates will always encircle inlets of this type without there being a gap.

For valves having angular cross-section bodies, there are rosettes which are already known which are clamped between the valve body and the wall which may be deformed round a screw-thread, for instance. A disadvantage with this type of known rosette is that when the angular cross-section valve body is tightened by turning it to screw the shank into a screw thread provided in or behind the wall, rather severe damage to the chromium layer of the rosette or even cracking and noticeable deformation of the rosette cannot always be avoided, partcularly when the angular cross-section valve, to be screwed into a certain final position, can only be moved with fairly great exertion into the final position.

According to the present invention, there is provided a sanitary water fitting comprising a body having a screw-threaded shank projecting from one end, termed the wall end, of the body for mounting the body on a wall, the body, at least at its wall end having an angular cross-section and the diameter of the shank being smaller than the width and depth of the crosssection of the wall end of the body, there being provided at the wall end of the body surrounding the shank an escutcheon plate and a ring or washer made of a resilient material and located between the wall end of the body and the escutcheon plate or on the side of the latter remote from the wall end of the body, whereby the ring or washer is arranged for being compressed, when the body is mounted on a wall, between the body and the escutcheon plate or between the escutcheon plate and the wall.

By providing a ring or washer of a resilient material between the wall end of the body of the sanitary water fitting and the escutcheon plate or between the latter and the wall it is easier to turn the body of the fitting into its final desired position, and damage to the escutcheon plate is less likely to occur.

Preferably, the ring or washer is made of rubber or plastics and is provided between the wall end of the body and the escutcheon plate.

It will be appreciated that with a construction in accordance with the invention, the disadvantages inherent in known designs, as mentioned, cannot arise.

In order to transfer the tightening forces more satisfactorily there is, according to a preferred feature of the invention a pressure plate located between the wall end of the body and the rubber or plastics ring or washer, which means that the rubber or plastics ring or washer is, in use, in a protected position behind the pressure plate.

In order to avoid damage to the surface of the pressure plate when the body is tightened, a friction disc, preferably made of paper or vulcanised fibre, may be disposed between the wall end of the body and the pressure plate.

In a preferred construction, the escutcheon plate, is provided with a recess to accommodate the rubber or plastics ring or washer, the pressure plate and also the friction disc, the combined thickness of these parts corresponding to, or approximately to, the depth of the recess. In this way a compact structural unit with a virtually unbroken exterior is produced.

The fitting in accordance with the invention can be produced easily and with relatively low expenditure.

The invention may be carried into practice in a number of ways but one specific embodiment will now be described, by way of example only, with reference to the accompanying drawing, in which: Figure 1 is a front elevation of a fitting in accordance with the invention, comprising a wall inlet, represented by dot and dash lines, and an escutcheon plate, and Figure 2 is a side elevation of the fitting shown in Figure 1 with the escutcheon plate shown in section.

The wall inlet shown consists of an angular cross-section tubular body 3 the wall end 4 of which has a screw-threaded shank 5, the diameter of which is smaller than the width and depth of the crosssection of the tubular body at its wall end.

An escutcheon plate is provided at the wall end of the body surrounding the shank 5.

As is evident, there are a rubber or plastics ring or washer 7, a pressure plate 8 and a friction disc 9 made of paper or vulcanised fibre, located between the wall end 4 of the tubular body 3 and the escutcheon plate 6. Parts 7, 8 and 9 are provided in a recess 10 in the escutcheon plate 6 and their combined thickness corresponds to the depth of the recess 10.

The friction disc 9 is disposed between the end 4 of the tubular body 3 and the pressure plate 8 so that rotation of the tubular body 3 during installation will not score the pressure plate 8. The pressure plate 8 is of larger outside diameter than the friction disc 9 and its outside diameter corresponds to the inside diameter of the recess 10 in the escutcheon plate 6 so that as viewed from the front (see Figure 1) the pressure plate 8 occupies the area around the end 4 of the tubular body 3 inside the escutcheon plate 6. The pressure plate 8 bears against the rubber or plastics ring or washer 7 which is of similar outside diameter and which has an internal diameter approximately equal to the inside diameter of the escutcheon plate 6.The rubber or plastics ring or washer 7 is thus resiliently compressed between the escutcheon plate 6 and the wall end of the tubular body 3 acting on the pressure plate 8 so that on tightening the tubular body there is a gradual increase in the tightening force.

As a result of the provision of the rubber or plastics ring or washer 7, the wall inlet may be tightened easily and without great exertion and be moved into the desired final position. Damage to the escutcheon plate no longer arises.

As already mentioned, the construction represented and described is only by way of example. The invention is also applicable to wall-mounted taps having angular crosssection bodies, for example; the angular cross-sectioned body of the fitting may be tubular or not and may be intended to be mounted on a room wall or on a wall of an article of sanitary furniture such as a washbasin, or bath. It is further possible to dispense with the pressure plate and the friction disc; obviously the rubber or plastics ring or washer would then have to have a smaller diameter. Finally, the ring or washer could alternatively be disposed on the side of the escutcheon plate remote from the wall end of the body so that when the body is mounted on a wall (not shown) the ring or washer is compressed between the escutcheon plate and wall.It is primarily of importance that there is a structural member of a resilient material provided between the wall end of the inlet tubular body and the wall.

In the example illustrated, the outer face of the pressure plate 8 may of course be provided with a surface matching or co-ordination with the surface finish of the escutcheon plate 6 to provide a pleasing appearance of the assembly.
