Abstract

A universal water closet pan comprises a foot (3) which extends rearwards to create an inverted U-shaped bridge (12) which juts beyond the discharge mouth (6) and masks the discharge connector (13, 130), while acting as a support for a flushing cistern (14).

Description

The present invention relates to a water closet pan of universal type, ie constituted in such a manner as to be able to be installed with horizontal or wall discharge or alternatively with vertical or floor discharge, and with its cistern either mounted to form a back-rest or wall-mounted, without requiring special assembly arrangements or further component elements beyond those which are strictly essential, ie the bowl and the cistern for the flushing water. An example of such a water closet is shown in US-A-4,162,548.
According to the invention, the said pan comprises a bowl supported by a hollow support foot, this latter extending rearwards to define a type of inverted U-shaped bridge arranged to mask the discharge mouth and connection whether discharging through the wall or through the floor.
Moreoever, said bridge extends beyond the rear edge of the bowl and terminates below the rim in order to receive and support the base of a flushing cistern, the side walls of which form a direct extension of the front and plan profiles of the respective bowl.
These and further merits and constructional characteristics of the invention will be more apparent from the detailed description given hereinafter with reference to the figures of the accompanying drawings in which:

Figure 1 is a longitudinal section through the pan according to the invention;
Figure 2 is a rear view thereof;
Figure 3 is a front half-sectional view through the flushing cistern with its cover;
Figure 4 is a section on the line IV-IV of Figure 3;
Figure 5 is an overall side view of the invention; and
Figure 6 is the projection of Figure 5 from above, but excluding the bowl cover.

Said figures, and in particular Figure 1, show a water closet pan comprising a bowl 1 provided with a closed rim 2 and supported by a hollow support foot 3 provided with the normal holes 4 for fixing it to the floor.
The hollow foot 3 houses a normal syphon 5 which terminates in a rear discharge mouth 6, and the rim 2 opens into a rear mouth 7 for feeding the flushing water.
Said mouth 7 is masked by a respective rear ledge 70 branching from the upper edge of the bowl 1 and coplanar with this latter (Figure 5), its side edges being on the direct extension of the outer surface of said bowl 1 (Figures 2 and 6).
Furthermore, straddling the feed mouth 7 (Figure 6) there are two through holes 8 for fixing a normal seat 9 provided with a cover 10 (Figure 5), the lower annular wall of the rim 2 comprising a plurality of conveniently distributed discharge holes 11.
The foot 3 extends towards the rear zone of the pan 1 to form a sort of bridge 12 of inverted U configuration (Figure 2).
The rear terminal part of the bridge 12 juts beyond the overlying ledge 70, and its upper wall lies between the feed mouth 7 and discharge mouth 6.
As clearly shown in Figure 1, this latter mouth can receive either a right angled connector 13 for discharge through the floor, or a horizontal straight connector 130 for discharge through the wall.
Said connectors 13 and 130 are practically masked by the bridge 12.
The water closet pan according to the invention can be installed in one of the aforesaid ways, ie with discharge either through the floor or through the wall, and with the cistern mounted either to form a back-rest as shown or wall-mounted, in this latter case there being provided a suitable connector, not shown, for connecting the feed mouth 7 to said wall-mounted cistern.
As clearly shown in all the accompanying figures, the jutting part of the bridge 12 is designed to receive and support a flushing cistern comprising a cistern body 14 and a respective cover 15 (Figures 3 and 4).
Said cistern 14 and cover 15 have their conjugate coupling edges of stepped configuration.
The lower part of the cistern 14, ie that intended to be inserted behind the bowl 1, comprises a central recess 16 which communicates with the cistern 14 by way of an upper aperture 17.
Furthermore, the front wall of the recess 16 is provided with an aperture 18 for the passage of a suitable connector, not shown, which connects the feed mouth 7 to the aperture 17.
As best shown in Figure 5, straddling the front aperture 18 there are provided two through holes for receiving respective stay bolts 19 which are connected to the bolts 20 for fixing the seat 9 on to the ledge 70 of the bowl 1.
In this manner, the cistern 14 remains fixed to the water closet pan, by which it is supported by way of the bridge 12.
Correct positioning of the cistern 14 on the bridge 12 is ensured by a profiled undercut 21 (Figures 3 and 4) which is conjugate with the upper wall of the bridge (Figure 2).
Furthermore, as best shown in Figures 3 and 4, the cover 15 is provided centrally with a hole 22 for fitting a normal control member for discharging the cistern 14, the rear wall of this latter comprising a hole 23 for connection to the water main.
As shown in Figures 3, 4, 5 and 6, above the recess 16, the combined front surface of the cistern 14 and cover 15 is configured as a portion of a vertically extending concave cylindrical surface perimetrally enclosed by a facia 24 which substantially reproduces the same shape as the outline of the bowl 1 (Figure 1).
The lower part of said facia 24 (Figures 4, 5 and 6) overlies the upper terminal edge of the ledge 70, and the side walls (Figure 6) and lower walls (Figure 2) of the cistern 14 constitute the direct extension of the outer profile of the pan or bowl 1.
The assembly and installation of the invention wll be clearly apparent from the aforegoing.

Claims

1. A universal water closet pan of the type comprising a bowl (1) provided with a rim (2) and supported by a hollow foot (3) which houses a syphon (5) terminating in a horizontal rear discharge mouth (6), characterised in that the foot (3) extends rearwards to form a bridge (12) shaped as an inverted U, which juts beyond the discharge mouth (6) in order to mask a discharge connector (13), (130), and of which the upper wall, which lies between the discharge mouth (6) and the plane in which the lower edge of the rim (2) lies, is arranged to receive and support a cistern (14) mounted to form a back-rest.

2. A pan as claimed in claim 1, characterised by comprising, above a normal rear feed mouth (7) for the flushing water directed towards the rim (2), a ledge (70) which is coplanar with the mouth of the bowl (1) and which constitutes the direct extension of the outer lateral surface of this latter, in order to provide a front support for the cistern (14).

3. A pan as claimed in claim 1, characterised in that the cistern (14) is provided lowerly with a central recess (16), the vertical extent of which is substantially equal to the distance between the upper wall of the bridge (12) and the upper face of the ledge (70), said central recess (16) comprising an upper aperture (17) and a front aperture (18), and being suitable to receive a pipe for connecting together said two apertures (17), (18).

4. A pan as claimed in claims 1 and 3, characterised in that at the base of the cistern (14) there is an undercut (24) shaped to perfectly mate with the top of the bridge (12).
