A receiving plane suitable for carrying out the method and a monobloc plane/basin assembly thus obtained are also described. ## Claims ### Claim 1 A method for producing a basin (1) integrated in a work surface, called the receiving plane (2), comprising an upper surface (2a) and a lower surface (2b), according to which method the receiving plane is pierced right through and an opening (3) adapted to receive the basin is formed, wherein: an injection mould (10) for thermoplastic synthetic material is used, comprising: a first shell of generally concave shape, called the lower shell (12), adapted to bear on the lower surface (2b) of the receiving plane and at least one shell of generally convex shape, called the upper shell(s) (13, 13a, 13b), adapted to bear on the upper surface (2a) of the receiving plane and form with the lower shell a moulding cavity, called the impression (16), with the shape of the basin to be obtained, the receiving plane (2) is installed in the mould so as to clamp the periphery of the opening (3) of the receiving plane between the lower shell and an upper shell in such a way that at least part of the edge (3a) of the opening constitutes a continuous peripheral wall of the mould connecting the lower shell to the upper shell, a thermoplastic synthetic material is injected into the impression (16) so as to form a basin (1) moulded onto the receiving plane (2). ### Claim 2 (depends on 1) A method as claimed in claim 1, wherein each upper shell (13, 13a, 13b) of the mould (10) is adapted to bear in a planar manner on the receiving plane (2) and to form an upper wall of the impression (16) extending solely at the level of and below the level of the upper surface (2a) of the receiving plane in order to obtain a moulded-on basin (1) flush with the upper surface of the receiving plane. ### Claim 3 (depends on 1) A method as claimed in claim 1, wherein the lower shell (12) has a concave zone surrounded by a convex rim (19) extending along the edge (3a) of the opening, inside and at a distance from the edge, projecting relative to the level of the lower surface (2b) of the receiving plane in the direction of its upper surface (2a), said rim being adapted to enable the formation of a peripheral skirt (20) of the basin between the edge (3a) of the opening and said rim (19) during the moulding-on of the basin. ### Claim 4 (depends on 3) A method as claimed in claim 3, wherein the lower shell has a shoulder (21) at the base of the rim (19), facing the edge (3a) of the opening, adapted to enable the centring of the opening (3) of the receiving plane (2) relative to the injection mould (10). ### Claim 5 (depends on 4) A method as claimed in claim 4, wherein the shoulder (21) has at regular intervals an increased height in the direction of the upper surface (2a) of the receiving plane in order to divide the skirt (20) of the basin into independent sectors. ### Claim 6 (depends on 1) A method as claimed in claim 1, wherein during the injection stage, a single thermoplastic synthetic material (15) is used to form the basin (1). ### Claim 7 (depends on 6) A method as claimed in claim 6, wherein a thermoplastic synthetic material (15) chosen from polymethylmethacrylate and polycarbonates is used. ### Claim 8 (depends on 1) A method as claimed in claim 1, wherein during the installation of the receiving plane (2) in the mould (10), a reinforcing insert (26) adapted to be embedded in the synthetic material injected at the injection stage is fixed to the receiving plane and/or the lower shell (12). ### Claim 9 (depends on 1) A method as claimed in claim 1, wherein the injection stage is divided into two passes, a first pass using a first upper shell (13a) defining a first impression (16a) set back relative to the upper surface (2a) of the receiving plane and a first synthetic material chosen to impart a desired mechanical strength to the basin and a second pass using a second upper shell (13b) defining a complementary impression (16b) above the first impression and a second synthetic material chosen to provide a desired surface finish for the basin. ### Claim 10 (depends on 9) A method as claimed in claim 9, wherein a first synthetic material chosen from ABS, polycarbonates and polyamides is used, and a second synthetic material chosen from polymethylmethacrylate and polycarbonates is used. ### Claim 11 (depends on 1) A method as claimed in claim 1, wherein during the formation of the opening (3) in the receiving plane (2), anchoring means (22, 23, 24, 25) adapted to enable the anchoring of the moulded-on basin to the receiving plane are produced on and/or in the vicinity of the edge (3a) of said opening. ### Claim 12 (depends on 11) A method as claimed in claim 11, wherein said anchoring means have at least one radial groove (22) formed in the edge (3a) of the opening, parallel to the surfaces (2a, 2b) of the receiving plane. ### Claim 13 (depends on 11) A method as claimed in claim 11, wherein a receiving plane (2) comprising a supporting panel (8) covered with a decorative sheet (9) on the upper surface of the receiving plane is used, and wherein at least one radial groove (22) is formed in the supporting panel (8), its width being limited in the direction of the upper surface (2a) of the receiving plane by the decorative sheet (9). ### Claim 14 (depends on 11) A method as claimed in claim 11, wherein said anchoring means further have an orthogonal groove (23) formed in the lower surface (2b) of the receiving plane, substantially parallel to the contour of the opening (3), and connected to the latter by a radial recess (24) of said lower surface. ### Claim 15 (depends on 12) A method as claimed in claim 12, wherein a series of holes (25) are made in the lower surface (2b) of the receiving plane which are orthogonal to this surface, regularly spaced on the contour of the opening (3), at a distance from the edge (3a) of the latter, pass through the radial groove(s) (22) without opening onto the upper surface (2a) of the receiving plane, and are adapted to form a radial anchorage of the basin and also a compensating space for the injected synthetic material. ### Claim 16 (depends on 1) A method as claimed in claim 1, wherein during the formation of the opening (3) in the receiving plane, indexing receptacles (4) are made in the lower surface (2b) of the receiving plane which are adapted to cooperate with projections (5) formed on the lower shell (12) in order to position and hold the receiving plane (2) in the injection mould (10). ### Claim 17 (depends on 1) A method as claimed in claim 1, wherein the lower shell (12) has means (27, 28) for immobilising the receiving plane (2) which are adapted to

has bosses (18) interrupting the continuity of the impression (16) and adapted to form orifices in the basin (1) during the moulding-on. ### Claim 19 (depends on 1) A receiving plane (2), suitable for

basin (1) is moulded onto the edge (3a) of an opening (3) formed in the receiving plane (2).
