Definitions
- the present invention relates to a sink and to a corresponding manufacturing method.
- the rim of the perforated seat of the worktop and the rim of the sink are milled so that each has a contact surface that is inclined with respect to the vertical (in the operating condition of the sink);
- the rim of the perforated seat of the worktop is subjected to grinding, providing a sort of frame defined by orthogonal walls (one vertical and one horizontal) which accommodate the peripheral rim of the sink, which is also subjected to grinding for this purpose, taking care to leave (between the frame and the rim of the sink) tolerances suitable for the insertion of sealing compounds and/or adhesives.
- sinks made of composite material are manufactured by injection molding: this technology necessarily leaves on the rim of the sink a draft wall which then extends into a curved blending surface.
- the sink made of composite material is suitable for "standard” mounting, but if it has to be “flush” mounted it must necessarily be machined by removing material from the rim and therefore it is not possible to provide for a new and different use thereof in standard mounting.
- the aim of the present invention is to provide a sink that is capable of improving the background art in one or more of the aspects mentioned above.
- an object of the invention is to provide a sink, preferably made of composite material, that can be utilized without modifications in at least two different installation solutions, thus reducing the cost and the difficulties of installation linked to the milling machining of the rim of the sink.
- Another object of the invention is to provide a method for manufacturing a sink according to the invention.
- Another object of the invention is to provide a sink that is highly reliable, relatively easy to provide and has competitive costs.
- the sink according to the invention comprises a concave body 2 and a free rim 3 which is connected to the concave body 2.
- the free rim 3 of the sink is recognizable because it constitutes the portion of the sink 1 that protrudes outward with respect to the concave body 2.
- the latter comprises in turn side walls 21 and a bottom 22.
- the sink 1 is configured to be installed on a worktop P, shown in Figures 1, 2 , 5 and 6 .
- the worktop P is for example a top of a kitchen, of a bathroom cabinet or the like.
- the overall shape, in top plan view, of the sink 1 can be any: the figures show, by way of example, a sink 1 having a substantially rectangular plan shape, but the shape might also be different, for example oval or round or shaped in another way. Furthermore, the sink may have multiple basins.
- the rim 3 comprises a peripheral end portion 4 which, along a vertical sectional plane (with the sink 1 in the operating configuration), comprises a first part 41 and a second part 42 which are substantially rectilinear, the angle ⁇ formed between an extension of the first part 41 and the second part 42 being comprised between 1° and 45°.
- the peripheral portion of the rim 3 has two perimetric surfaces which are extended along the entire thickness of the rim 3 of the sink 1 and around the perimeter of the sink 1: a first rectilinear surface which is extended along the first part 41 and a second rectilinear surface which extends along the second part 42.
- the angle between the extension of the first surface and the second surface is comprised between 1° and 45°, like the one comprised between the first part 41 and the second part 42.
- the first part 41 of the peripheral end portion 4 is inclined with respect to a vertical axis V by an angle ⁇ comprised between 0° and 9° when the sink 1 is in the operating configuration.
- this inclination in fact fulfills the role of the "draft" needed in order to extract the sink from the mold.
- the sink 1 according to the invention is in fact made of composite material and is manufactured by injection molding.
- the first part 41 and the second part 42 of the peripheral end portion 4 are provided together with the rim 3 and monolithically with said body 2 in the same injection molding operation.
- the rim 3 comprises a lower surface 31 and an upper surface 32 which are opposite and substantially parallel to each other and are visible in the sectional detail view of Figure 4 ; the lower surface 31 and the upper surface 32 are connected by the peripheral end portion 4.
- the lower surface 31 is directly adjacent to the first part 41 of the peripheral end portion 4 and the upper surface 32 is directly adjacent to the second part 42 of the peripheral end portion 4.
- the lower surface 31 comprises an external portion 33 which is subjected to grinding or on which a removal of material is equivalently provided, and which therefore is the part of the lower surface that is nearest the first part 41.
- the method for manufacturing the sink 1 provides for the step of providing, in the same operation as molding a moldable material, the body 2 and the free rim 3 of the sink 1, the free rim 3 being molded so as to have a peripheral end portion 4 which, along a vertical sectional plane with the sink in the operating configuration, comprises a first part 41 and a second part 42 which are substantially rectilinear, the angle formed between an extension of the first part and the second part being comprised between 1° and 45°.
- the method according to the invention provides for the step of providing an operation for removing material 33 at a lower surface 31 of the rim 3 in order to provide an external portion 33 subjected to grinding that is proximate to the first part 41.
- the sink 1 according to the invention can be installed equally in a "standard” manner, as in Figure 1 , or in a “flush” manner, as in Figure 2 , without the need for additional operations on the sink, as is evident also from Figures 5 and 6 .
- the rim of the sink 1 thus provided does not need to be machined again as a function of the chosen installation (as occurred instead in the cases of the background art), but is already aesthetically finished, adapting to both shown types of installation.
- the inclination of the second part 42 which in the installed configuration of the sink is the one that is installed highest, constitutes a seat for the application of a sealing compound M when the sink 1 is installed "flush".
- the distance between the rim 3 of the sink 1 and the worktop P is reduced even in the absence of additional machining on the sink, with a consequent reduction of the quantity of compound M applied during finishing in the slit between the two.
- An additional advantage deriving from the invention 1 is to reduce the number of types of sinks that have to be kept in stock for the different installations.
- the materials used, as well as the contingent shapes and dimensions may be any according to the requirements and the state of the art.
