Description

BACKGROUND OF THE INVENTION

The present invention relates to a system for making outlet or draining assemblies for wash basins and sanitary articles in general.
As is known, a lot of wash basins and bidet constructions, having different water draining assemblies, are commercially available.
Actually, the above mentioned prior wash basins can be classified into wash basins which do not include overflow holes, wash basins including an overflow hole to be connected to an outer duct, or wash basins in which the overflow duct is directly formed inside the wash basin body.
In addition to the above mentioned different constructions, prior wash basins are conventionally installed by using different assembling methods: that is by mounting them in a recessed wall, or by supporting them on a supporting surface.
Thus, it would be necessary to provide a great amount of different outlet assemblies, depending on the different types of the wash basins to be assembled.
Accordingly, it is further necessary to store a lot of different outlet or draining assemblies, since a single draining assembly cannot be fitted to a different type of wash basin.
The document GB-A-765687 discloses a system according to the preamble of claim 1.

SUMMARY OF THE INVENTION

The aim of the present invention is to solve the above mentioned problem, by providing a system which allows a wash basin or sanitary article in general to be mounted with its outlet above the supporting or bearing surface of a supporting plane.
According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a system for making outlet or draining assemblies for wash basins and sanitary articles in general, according to the main claim.

BRIEF DESCRIPTION OF THE DRAWINGS

Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of a system , which is illustrated, by way of an indicative, but not limitative, example in the accompanying drawings, where:

Figure 1 shows the system according to the present invention, including a wash basin having an inner overflow assembly and mounted on a supporting surface;
Figure 2 shows the subject system including a wash basin which does not include any overflow assembly, and is supported on a supporting surface;
Figure 3 shows the system according to the present invention including a wash basin having an outer overflow assembly, and mounted in a supported relationship on a supporting surface;
Figure 4 shows a system not according to the present invention including a wash basin having an outer overflow assembly, and recessed in a surface; and
Figure 5 shows a wash basin, which does not include any overflow assemblies, supported on a supporting surface, with a locking counter-nut.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the number references of the above mentioned figures and, more specifically, to figure 1, the system for making outlet or draining assemblies for wash basins and sanitary articles in general, according to the present invention, comprises a drain 7 having perimetrical openings 7a, which can be arranged at the outlet mouth of a wash basin 2, including an inner overflow assembly.
As shown, the drain 7 is coupled, through a drain sealing gaskets 10 and 15 with said wash basin outlet mouth, and is held in its set position by a clamping cap 11, in the case in which the wash basin is mounted in a recessed relationship on a mounting surface 5.
The drain 7 can be closed by a plug element 9, to which an opening and closing mechanism is coupled.
The wash basin 2 is assembled by causing it to bear on the surface 4, and a spacer solid ring element 13 is provided, which must be arranged under the wash basin outlet mouth, between a sealing gasket 15 and an O-ring 24, arranged above the supporting or bearing surface.
Moreover, a throughgoing tube or pipe 25 having an axial length which depends on the thickness of the supporting surface or plane is provided.
With reference to figure 2 , a wash basin 1 devoid of any overflow hole is herein shown.
In this case, a drain 6 without holes connected to the outlet mouth of the wash basin through a drain gasket 10 is used, said drain being provided with a fixed plug element 8 which does not allow to carry out a full closure.
For installing the wash basin both on the supporting plane or surface 4 and not according the invention on the embedding plane 5, the same components as those thereinabove illustrated are used.
With reference to figure 3, is herein shown a wash basin 3 having an outer overflow assembly and, in this case, a fixing pin 18 to be engaged in the overflow hole is provided.
Said overflow hole is coupled, through a sealing gasket 19, to an overflow body 17 which, through a fixing ring element 23, is in turn coupled to a pipe 22 engaging with a further fixing ring element 23.
Said ring element 23 is coupled, by a coupling insert 20, to an overflow ring element 14, to be arranged above the bearing plane or surface 4.
Between said coupling insert 20 and overflow ring 14 a sealing gasket 21 is arranged.
Figure 4 shows a wash basin, provided with an outer overflow assembly, of the above mentioned type, which is coupled to an embedding plane 5.
Figure 5 shows a wash basin, which does not include any overflow assembly, and being indicated by the reference number 1, of the types shown in figures 2, with the sole difference that, instead of the drain coupling cap element, is used a counter-nut 12, engageable with a counter-nut sealing gasket 16.
All the above disclosed components allow to provide a substantially automatic fitting.
The invention, as disclosed, is susceptible to several modifications and variations, all of which will come within the scope of the invention as defined in the appended claims.
In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements.

Claims

A system comprising a wash basin (1, 2, 3) or sanitary article in general, an outlet or draining assembly and a supporting surface, wherein said outlet or draining assembly comprises a drain (6, 7) which can be coupled to an outlet mouth of the wash basin (1, 2, 3), or sanitary article in general, a closure plug element (8, 9) which can be introduced into said drain (6, 7), a fixing element (11) or counter-nut (12) for fixing said drain (6, 7), an optional overflow assembly for an overflow outlet, and sealing gaskets (10, 15, 21) adapted to be interposed between said elements, characterized in that said outlet or draining assembly further comprises a spacer solid ring element (13, 14)), which is assembled above the supporting surface (4) of the wash basin (1 ,2, 3) or sanitary article in general with or without said overflow assembly, and that said outlet or draining assembly further comprises an O-ring (24) whereby the spacer solid ring element (13, 14) is arranged under the wash-basin outlet, between a sealing gasket (15) and the O-ring (24) and above the supporting surface (4), said fixing element (11) or counter-nut (12) fixing said drain (6, 7) from underneath said supporting surface (4).
