Definitions

  • This invention relates to a recessed WS basin. More in particular, this invention relates to a basin for washing WC bowls.
  • bowls are usually installed in bath-rooms, which are connected to above standing wall-fastened water basins.
  • the water contained in the basin is discharged in said bowl.
  • WC basins are usually made from plastic, metal and ceramic material, and may be applied either outside or inside the wall.
  • Externally applied basins have a removable lid, which gives access to the inside, to perform operations of installation, maintenance or replacement of the various components, such as, for instance, float ball, valve, gaskets and so on.
  • recessed basins Internally applied, i.e. recessed basins, are housed in a special hollow space or directly cemented in the thickness of the wall, above the bowl.
  • This second type of basin is very common and ofted preferred, especially in small bath-rooms, as it does not take up room and it allows to put the bowl very near the wall.
  • the utilization of recessed basins allows also to obtain an aesthetical advantage, as only a panel of limited size is fastened to the wall to cover the opening and the inspection hollow space necessary for maintenance.
  • the panel may be provided with a button which causes the delivery of the water downflow.
  • a first drawback takes place during the stage of installation of the basin into the recess provided in the wall and concerns the fact that the net utilized to facilitate the anchoring of the plastering, is caused to be integral with the opposing surfaces by simple glueing. This connection of the net is quite precarious and tends to detach, partly or fully, so that the net has to be re-fixed to the basin walls, to allow the anchoring of the plastering.
  • the drain is made up by different parts which are assembled in the inside of the basin, which involves uncomfortable interventions by the operator.
  • An object of this invention is to obviate the generically aforementioned drawbacks.
  • an object of this invention is to provide a recessed WS basin allowing in the first place the efficient and final fastening to its surfaces of the plaster anchoring net.
  • a further object of this invention is to provide a recessed WC basin allowing an easy and quick introduction and removal of the drain and valve body as well as the float ball as "one integral body”.
  • a further object of this invention is to provide a recessed WS basin allowing to obtain a noiseless and particularly a quick water flow.
  • a further object of this invention is to provide a recessed WC basin suitable to ensure a high level of reliability and duration with time, and also such as to be easily installed.
  • a recessed WS basin comprising a cabinet of a substantially parallelepipedal form, provided in the lower part with a pipe union and with top-placed flanges, with holes for the mechanical positioning, as well as an opening or window on the front, characterized basically in that said pipe union and said window are offset relatively to the centre line of said cabinet.
  • the recessed WS basin subject matter of this invention comprises a cabinet (12) having a substantially orthogonal parallelepipedal shape and a limited depth, and advantageously integrally made according to the well known technique of blow-moulding of an indeformable and recyclable thermoplastic material.
  • Said cabinet (12) comprises a front surface (12") and a back surface (48) parallel relatively to one another and connected by a side band (12').
  • Said cabinet (12) is provided, in correspondence of the upper side corners, with slight bevels (14), from which flanges (16) develop which have substantially triangular sections.
  • Each flange (16) has the free sides aligned with the side band (12') of said cabinet and is provided with holes (18).
  • cabinet (10) has also a markedly extended bevelled portion.
  • Each of the aforementioned bevelled portions forms an inclined wall (20, 20'), with a different angle, from which a flange (22) develops centrally, having a substantially triangular section and whose free sides are aligned with the side band (12') of cabinet (10).
  • the lower flanges (22), just as the upper ones (16), are provided each with a hole (24).
  • the function of said holes (18,24) is to hang up or mechanically fasten basin (12) in the special recess, through generic square hooks or the like.
  • the recessed WC basin subject matter of this invention is provided with a pluratily of dead holes or hollow spaces (26), placed near the perimeter along the opposing front (12") and back surfaces.
  • Said dead holes (26), obtained in the blow-moulding stage of basin (12), are the seats for housing stem (28) of a plug provided with a head (30) or some other mechanical means suitable for anchoring a net (32).
  • the tightly-meshed net (32) is then mechanically fastened definitively to the opposing front (12") and back surfaces of basin (12) my means of said plugs, as shown on Fig. 2.
  • Head (30) of the plugs having by way of example and preferably a round shape, has a larger diameter compared to the width and/or height of the meshes which form said net.
  • the WC basin subject matter of this invention is provided in its lower end, with a pipe union (34) integral with said basin, having being obtained in the blow-moulding stage.
  • Pipe union (34) develops towards the outside in an off-center position relatively to the vertical axis or central axis of the parellelepiped which forms the WC basin (12).
  • Pipe union (34) develops from a limitedly extended flat portion (36) of side band (12') in correspondence of the lower part of basin (12), said flat portion (35) being circumscribed by and connected to the inclined walls (20, 20').
  • the aforementioned opposing inclined lower walls (20, 20') have a different inclination.
  • the flat portion (36) to which said inclined walls (20, 20') are connected is off-centered; also off-centered is pipe union (34) which ??? projects outwards from said flat portion (36).
  • Said pipe union (34) is shifted relatively to the vertical axis of the parallelepiped of basin (12) by a length comprised, by way of example, between 50 and 60 mm.
  • At least the front surface (12") of basin (12) is provided, parallelly to the axis of pipe union (34) and at a short distance from same, with two prints near to one another.
  • Said prints (38) develops in depth, are shaped, by way of example and preferably, as diamonds, and have a lenght indicatively comprised between 40 and 100 mm.
  • Said prints (38), which are shown in detail on Fig. 5, are a guide for the self-centering of the drain which is inserted into basin (12), as shall be specified in the following.
  • Basin (12) is also provided with a conventional window provided on the front surface (12"), through which the internal components are inserted and then assembled. Said window is off-centre and its vertical axis coincides with the one of pipe union (34). It is circumscribed by a frame (44) provided with at least a branch (46) integral with the opposing surface of basin (12); more precisely, to the inner surface of back wall (48) (see Fig. 4).
  • Frame (44) advantageoulsy made from rigid thermoplastic material, is preferably fastened to basin (12) by means of generic screws, both to the front surface (12") along the perimeter (50) of the window and to the opposing back surface (48). Said frame, inasmuch it develops also transversally in basin (12), is an excellent support for the float ball group (52) and constitutes a further element for the transversal stiffening of the basin.
  • a drain (54) is inserted, advantageously integrally made, suitable to house a conventional waste valve (not shown).
  • the aforementioned drain is constituted by a tubular element (56) having a reduced height and a diameter slightly smaller that that of pipe union (34), inserted in said pipe union.
  • a gasket from rubber or the like is fitted on said tubular element (56).
  • a strip (58) of limited thickness is integral with the tubular element (56), said strip being in its turn connected to a flexible strip (60). The length of said strip (60) is such that it reaches with its upper end the height of window (50) when element (56) is fitted into the final seat of pipe union (34).
  • Drain (54) is correctly positioned in the recessed WC basin by inserting the jack, placed at the upper end of the flexible strip (60), into the special elastic seat provided in the back part of window (50); said positioning is obtained by snap- inserting the jack into the elastic seat, in a very easy way.
  • the float ball (52), introduced into basin (12) through window (50), is positioned and fastened by means of a special threaded locking ring, in the special seat of branch (46) of frame (44).
  • said group (52) being supported adequately, does not give rise to noisy vibrations and cannot be positioned in positions unsuitable for a correct working.
  • drain (54) can be achieved very simply and quickly, thanks to the presence of prints (38) which by extending towards the inside of the cabinet, guide said drain, causing it to self-center and to exactly fit into pipe union (34): the flexible strip (60) allows to introduce and easily position said drain into basin (12) and to place it in its seat. As much easy and quick are the interventions for removing the float ball group (52) and/or drain (54), for maintenance reasons.
  • the recessed WC basin subject matter of this invention solves the known problems connected with the installation of recessed basins and with the maintenance of same with time.
  • This construction allows to achieve remarkable savings both of installation and in case of maintenance interventions or replacement of parts.
  • prints (38) could be obtained, shaped and /or developed in length or width differently from what has been described and illustrated by way of example for the self-centering of the drain (54).
  • frame (44) could have two or more branches, and possibly a plate for the support and fastening of the float ball group (52).
  • the lower inclined walls (20, 20") of basin (12) could have a concave or convex development instead of a straight one.
