Description

L'invention concerne un procédé d'intégration d'une vasque à un plan récepteur, en particulier plan sanitaire ou plan de travail de meuble de salle de bains ou de cuisine. Elle a également pour objet une vasque et un plan récepteur, solidarisés ou dissociés, intervenant dans la mise en oeuvre dudit procédé.The invention relates to a method of integrating a basin to a receiving plane, in particular sanitary plan or worktop of bathroom or kitchen furniture. It also relates to a basin and a receiving plane, solidarized or dissociated, involved in the implementation of said method.

Dans tout le texte, on désigne par "clipsage" un blocage par contact produisant après mise en place de deux éléments l'un par rapport à l'autre, un effet de verrouillage réciproque de ces deux éléments, selon au moins une direction axiale, la mise en place nécessitant une déformation élastique par l'exercice d'une force axiale de clipsage apte à produire cette déformation élastique et de valeur supérieure à une valeur minimale, non nulle, prédéterminé, dite résistance de clipsage. Un clipsage peut être réversible, le déblocage nécessitant l'exercice d'une force axiale inverse, dite force de déclipsage, supérieure à une valeur minimale, non nulle, prédéterminée, dite résistance de déclipsage, égale ou non à la résistance de clipsage. Un clipsage peut aussi être irréversible, et interdire tout déblocage des deux éléments (sauf déformation plastique, rupture ou ruine de l'un au moins d'entre eux).Throughout the text, the term "clipping" denotes a contact locking producing after placement of two elements relative to each other, a reciprocal locking effect of these two elements, in at least one axial direction, the implementation requiring elastic deformation by the exercise of an axial clipping force capable of producing this elastic deformation and greater than a predetermined minimum value, non-zero, said clipping resistance. A clipping can be reversible, the unlocking requiring the exercise of a reverse axial force, said unclamping force, greater than a minimum value, non-zero, predetermined, said unclipping resistance, equal or not to the clipping resistance. A clipping can also be irreversible, and prohibit any unlocking of the two elements (except plastic deformation, breaking or ruin of at least one of them).

La géométrie relative des deux éléments et les propriétés de déformation élastique du matériau rigide d'au moins un de ceux-ci font intervenir l'un au moins des trois phénomènes mécaniques suivants dans la réalisation d'un clipsage :

  • formation d'une butée axiale pouvant être effacée par déformation élastique ; on parle alors de clipsage par effet de cliquet,
  • frottement statique entre les portions des éléments venant en contact, la géométrie étant adaptée pour maintenir une contrainte élastique résiduelle résultant d'au moins une partie de la déformation élastique de clipsage ; on parle alors de clipsage par frottement,
  • effet de coin ; on parle alors de clipsage par effet de coin.
The relative geometry of the two elements and the elastic deformation properties of the rigid material of at least one of them involve at least one of the following three mechanical phenomena in making a clipping:
  • forming an axial abutment that can be erased by elastic deformation; we then talk about clicks by ratchet effect,
  • static friction between the portions of the elements coming into contact, the geometry being adapted to maintain a residual elastic stress resulting from at least a part of the elastic clipping deformation; we then speak of clipping by friction,
  • corner effect; we then talk about clipping by wedge effect.

Ce dernier type de clipsage se réfère non pas à un banal effet de coincement ou de blocage réciproque entre deux éléments en contact, mais vise un type de blocage bien particulier désigné par le terme technique consacré d'« effet de coin » qui, dans le cas présent, est produit essentiellement sous contrainte élastique d'une vasque et/ou d'un plan récepteur en un matériau rigide ayant des propriétés de déformation élastique.This last type of clipping refers not to a common jamming effect or mutual blocking between two elements in contact, but is a particular type of blocking designated by the technical term of "corner effect" which, in the In this case, is produced essentially under elastic stress of a basin and / or a receiving plane in a rigid material having elastic deformation properties.

Un clipsage peut faire intervenir plusieurs de ces phénomènes, voire la totalité d'entre eux.Clipping can involve many, if not all, of these phenomena.

De même, dans le texte, on entend par élément au repos, un élément qui n'est soumis à aucune contrainte mécanique.Similarly, in the text, the element at rest is an element that is not subjected to any mechanical stress.

Les meubles de salle de bains ou de cuisine possèdent un panneau supérieur formant un plan sanitaire ou de travail, dans lequel est encastrée une vasque, généralement vasque d'évier ou de lavabo ; ce panneau supérieur peut être habillé d'un revêtement (en particulier en stratifié) et est souvent désigné par "plan récepteur".The bathroom or kitchen furniture has an upper panel forming a sanitary or work plan, in which is embedded a basin, usually basin sink or sink; this top panel can be covered with a coating (particularly laminate) and is often referred to as a "receiving plane".

De nombreuses techniques permettant d'intégrer la vasque dans le plan récepteur ont déjà été décrites. Schématiquement, après perçage d'une ouverture d'insertion de la vasque dans le plan récepteur, on positionne la vasque à l'intérieur de cette dernière à une certaine distance de ses parois. La vasque et l'ouverture définissent ainsi un espace libre périphérique destiné à constituer un volume de moulage d'un élastomère (notamment polyuréthanne) servant à la fois d'organe de fixation, de tampon d'amortissement et de joint d'étanchéité.Many techniques for integrating the basin in the receiving plane have already been described. Schematically, after drilling an insertion opening of the vessel in the receiving plane, the vessel is positioned within the latter at a distance from its walls. The basin and the opening thus define a peripheral free space intended to form a molding volume of an elastomer (especially polyurethane) serving as both fastener, damping buffer and seal.

Ces techniques présentent plusieurs défauts en ce qui concerne la qualité de fixation de la vasque et la qualité d'aspect du produit fini. La coulée d'élastomère dans le volume de moulage contient généralement des bulles (provenant de l'emprisonnement d'air lors de la coulée) qui affectent la qualité de la fixation. Le joint ainsi formé vieillit dans le temps avec des risques de variation de coloration et d'accumulation de salissure. Par ailleurs, lors de la fabrication (avant la coulée de l'élastomère), la vasque est difficile à positionner de façon parfaite par rapport au plan récepteur et un défaut de positionnement conduit à une esthétique très défectueuse du produit fini (vasque excentrée, entourée d'un joint d'épaisseur variable).These techniques have several flaws with regard to the quality of fixing of the basin and the quality of appearance of the finished product. The casting of elastomer in the molding volume generally contains bubbles (from entrapping air during casting) which affect the quality of the fastener. The seal thus formed ages in time with risks of color variation and accumulation of dirt. Moreover, during manufacture (before the casting of the elastomer), the basin is difficult to position perfectly in relation to the receiving plane and a positioning fault leads to a very defective aesthetic of the finished product (eccentric basin, surrounded by a seal of variable thickness).

Deux variantes majeures existent quant à la mise en place de la vasque dans l'ouverture d'un plan récepteur ; soit par le dessous du plan récepteur, soit par-dessus celui-ci.Two major variants exist as to the installation of the basin in the opening of a receiving plane; either from below the receiving plane, or over it.

Dans le cas d'une mise en place de la vasque par le dessous, les opérations de fixation sont complexes, et une mise en oeuvre imparfaite peut conduire, lorsque la vasque est en service, à un déplacement de celle-ci par rapport au plan récepteur, notamment à un écartement sous le poids de la charge ou même une dissociation.In the case of an installation of the basin from below, the fixing operations are complex, and an imperfect implementation can lead, when the basin is in use, a displacement of the latter relative to the plan receiver, especially at a distance under the weight of the load or even a dissociation.

Grâce à une bordure périphérique débordante, la vasque peut également être posée au-dessus de la surface supérieure du plan récepteur de façon à faire saillie par rapport à cette surface ( EP 0 471 964 ; FR-2729169 figure 5). Cependant, du fait de cette bordure périphérique débordante qui empêche l'écoulement des liquides du plan récepteur vers l'intérieur de la vasque, on observe une accumulation déplaisante et perpétuelle des liquides à ce niveau. Pour les mêmes raisons, la difficulté des opérations de nettoyage d'un tel plan sanitaire, ou plan de travail, se trouve considérablement accentuée.Thanks to an overhanging peripheral edge, the basin can also be placed above the upper surface of the receiving plane so as to protrude from this surface ( EP 0 471 964 ; FR-2729169 figure 5 ). However, because of this protruding peripheral edge which prevents the flow of liquids from the receiving plane into the basin, there is an unpleasant and perpetual accumulation of liquids at this level. For the same reasons, the difficulty of the cleaning operations of such a health plan, or work plan, is considerably accentuated.

Pour pallier cet inconvénient, il a été proposé de positionner la vasque dans une moulure aménagée dans le plan récepteur autour de l'ouverture de façon à assurer un effleurement de la vasque au niveau de la surface supérieure du plan récepteur ( EP 0 307 825 ; FR-2729169 figure 6 ; WO 99/57383 ). Cette pose avec affleurement de la vasque présente l'avantage d'assurer une continuité de surface entre vasque et plan récepteur, évitant les accumulations des liquides et souillures, et facilitant le nettoyage.To overcome this drawback, it has been proposed to position the basin in a molding arranged in the receiving plane around the opening so as to ensure a touch of the basin at the upper surface of the receiving plane ( EP 0 307 825 ; FR-2729169 figure 6 ; WO 99/57383 ). This installation with flush of the basin has the advantage of ensuring a continuity of surface between tub and receiving plane, avoiding the accumulation of liquids and dirt, and facilitating cleaning.

Que la vasque soit intégrée dans le plan récepteur par le dessous ou le dessus, l'intervention d'un professionnel est généralement conseillée, sous peine d'une pose imparfaite affectant la qualité et l'esthétique de l'ensemble.Whether the basin is integrated in the receiving plane from below or above, the intervention of a professional is generally recommended, otherwise imperfect pose affecting the quality and aesthetics of the whole.

La présente invention vise un procédé permettant un assemblage efficace et esthétique d'un plan sanitaire ou plan de travail de meuble de salle de bains ou de cuisine, tout en réduisant considérablement le coût global de la production industrielle et ce en faisant intervenir une vasque et un plan récepteur de fabrication simple et à moindre prix.The present invention relates to a process for an efficient and aesthetic assembly of a sanitary plan or worktop of bathroom or kitchen furniture, while significantly reducing the overall cost of industrial production and by involving a basin and a receiver plan simple manufacturing and cheaper.

Un objectif de l'invention est en particulier de fournir un ensemble plan récepteur-vasque dont l'assemblage permet un positionnement parfait de la vasque par rapport au plan récepteur et qui ne nécessite qu'une opération simple, rapide et à la portée d'un particulier sans compétence spéciale.An object of the invention is in particular to provide a receiver-sink assembly assembly whose assembly allows a perfect positioning of the vessel relative to the receiving plane and which requires a simple operation, fast and within range of an individual without special competence.

En vue de rendre la description plus claire, on supposera dans toute la suite le plan récepteur et la vasque dans leur position normale de service, les termes "haut", "bas", "supérieur", "inférieur" se référant à cette position.In order to make the description clearer, it will be assumed in the following the receiver plane and the basin in their normal position of service, the terms "high", "low", "superior", "lower" referring to this position .

Le procédé conforme à l'invention pour l'intégration d'une vasque à un plan récepteur comprend les opérations suivantes :

  1. (a) on réalise la vasque par moulage d'une matière synthétique rigide, avec une embouchure périphérique comportant une portion évasée vers le haut suivie d'une portion arrondie selon une direction centrifuge se terminant par un chant de formes et dimensions radiales hors tout prédéfinies,
  2. (b) on perce de part en part le plan récepteur et on réalise dans celui-ci une ouverture d'insertion de la vasque présentant sur chant, dans sa partie haute, un ressaut supérieur,
  3. (c) on met ensuite la vasque en place dans l'ouverture du plan récepteur en l'insérant par le haut, avec le chant en partie haute.
The method according to the invention for the integration of a basin with a receiving plane comprises the following operations:
  1. (a) the vessel is made by molding a rigid synthetic material, with a peripheral mouth having an upwardly flared portion followed by a rounded portion in a centrifugal direction terminating in a predefined radial shape and overall shape edge ,
  2. (b) the receiver plane is pierced right through and an insertion opening is made in the latter, with an upper projection on the edge of the vessel,
  3. (c) then put the basin in place in the opening of the receiving plane by inserting it from the top, with the edge at the top.

Selon la présente invention :

  • on réalise la vasque et l'ouverture avec des dimensions radiales hors tout du chant de la vasque au repos supérieures à celles du ressaut et adaptées pour qu'au moins une portion du chant de la vasque puisse venir, lors de la mise en place, au contact du ressaut en produisant un clipsage,
  • on positionne la vasque au-dessus de l'ouverture du plan récepteur de façon que son chant vienne au contact de la portion supérieure du ressaut,
  • on exerce sur la vasque une force d'insertion vers le bas adaptée pour déformer élastiquement le chant de la vasque et/ou le ressaut supérieur du plan récepteur et réaliser le clipsage de la vasque dans le plan récepteur.
According to the present invention:
  • the basin and the opening are made with radial dimensions overall of the song of the basin at rest greater than those of the projection and adapted so that at least a portion of the song of the basin can come, during the establishment, in contact with the projection by producing a clipping,
  • positioning the vessel above the opening of the receiving plane so that its song comes into contact with the upper portion of the projection,
  • the basin is exerted a downward insertion force adapted to deform elastically the edge of the basin and / or the upper projection of the receiving plane and perform the clipping of the basin in the receiving plane.

Le terme centrifuge utilisé ici fait référence à une direction qui s'éloigne de l'axe de symétrie de la vasque, sans pour autant désigner de façon limitative une direction radiale par rapport à cet axe.The term centrifugal used here refers to a direction away from the axis of symmetry of the basin, without, however, limitingly designating a radial direction relative to this axis.

Selon la géométrie du chant de la vasque et celle de l'ouverture du plan récepteur, plusieurs types de clipsage peuvent intervenir dans la cohésion plan récepteur-vasque : clipsage par frottement, clipsage par effet de coin, clipsage par effet de cliquet.According to the geometry of the edge of the basin and that of the opening of the receiving plane, several types of clipping can intervene in the cohesion receiver-sink plan: clipping by friction, clipping by wedge effect, clipping by ratchet effect.

Il est bien entendu qu'un clipsage conforme à l'invention peut impliquer plusieurs de ces phénomènes, voire la totalité d'entre eux.It is understood that a clipping according to the invention may involve several or all of these phenomena.

Comme on le comprendra mieux plus loin, un procédé d'intégration d'une vasque à un plan récepteur selon l'invention permet de fabriquer un ensemble monobloc plan récepteur-vasque, bénéficiant d'une fixation ferme et précise de la vasque dans le plan récepteur et dont l'assemblage ne nécessite aucune soudure ni collage, ni aucun organe de fixation mécanique rapporté. De façon inattendue, il est ainsi possible de réaliser des ensembles monoblocs plan récepteur-vasque dont la cohésion de l'ensemble est assurée uniquement par un effet de clipsage.As will be understood better later, a method of integrating a basin to a receiving plane according to the invention makes it possible to manufacture a one-piece receiver-basin unit assembly, benefiting from a firm and precise fixing of the basin in the plane. receiver and whose assembly requires no welding or gluing, or any mechanical fastener reported. Unexpectedly, it is thus possible to produce monoblock plan receiver-basin assemblies whose cohesion of the assembly is provided solely by a clipping effect.

Par ailleurs, aucun mouvement relatif plan récepteur-vasque, susceptible d'affecter le caractère esthétique de l'ensemble, n'est à craindre. Le mode de mise en place de la vasque conduit à une cohésion et une position parfaite de la vasque par rapport au plan récepteur.Moreover, no relative movement plan receiver-basin, likely to affect the aesthetic character of the whole, is to be feared. The installation mode of the basin leads to a cohesion and a perfect position of the basin relative to the receiving plane.

Avantageusement et selon l'invention, le chant du bord supérieur de la vasque présente une forme tronconique à sommet vers le bas définissant une arête supérieure et une arête inférieure, le diamètre de l'arête inférieure et celui de l'arête supérieure étant respectivement inférieur et supérieur au diamètre radial du ressaut. Une telle structure tronconique du chant du bord supérieur de la vasque offre des avantages à différents niveaux.Advantageously and according to the invention, the edge of the upper edge of the basin has a frustoconical shape with downward apex defining an upper edge and a lower edge, the diameter of the edge lower and that of the upper edge being respectively lower and greater than the radial diameter of the projection. Such frustoconical structure of the singing of the upper edge of the basin offers advantages at different levels.

D'une part, la mise en place de la vasque se trouve considérablement facilitée grâce à une insertion par glissement du chant de la vasque sur le rebord de l'ouverture, jusqu'au point de clipsage au niveau du ressaut. D'autre part, la résistance de clipsage est significativement améliorée. En effet, au clipsage par frottement dû au simple contact sous contrainte élastique, vient s'ajouter un effet de coin produit par le rebord supérieur de la vasque, aigu, venant au contact du ressaut. Cet effet de coin se trouve considérablement accentué lorsque le ressaut présente une certaine souplesse superficielle, par exemple dans le cas d'un plan récepteur surmonté d'un revêtement de polymère de type chlorure de polyvinyle, favorisant une insertion de l'arête supérieure du chant de la vasque dans l'épaisseur superficielle du ressaut.On the one hand, the installation of the basin is greatly facilitated through a sliding insertion of the edge of the basin on the rim of the opening, to the point of clipping at the projection. On the other hand, the clipping resistance is significantly improved. Indeed, the friction clipping due to the simple contact under elastic stress, is added a wedge effect produced by the upper edge of the basin, acute, coming into contact with the projection. This wedge effect is considerably accentuated when the projection has a certain superficial flexibility, for example in the case of a receiver plane surmounted by a polyvinyl chloride polymer coating, favoring insertion of the upper edge of the edge of the basin in the superficial thickness of the projection.

De préférence, le chant du bord supérieur de la vasque forme un angle solide α compris entre 5° et 15°. On entend par angle solide α compris entre 5° et 15°, un angle solide définissant, en section, un angle plan α de mesure comprise entre 5° et 15°.Preferably, the edge of the upper edge of the basin forms a solid angle α of between 5 ° and 15 °. The term solid angle α between 5 ° and 15 °, a solid angle defining, in section, a plane angle α of measurement between 5 ° and 15 °.

Avantageusement et selon l'invention, le ressaut de l'ouverture est une paroi cylindrique sensiblement verticale, c'est-à-dire sensiblement orthogonale à la face principale du plan récepteur.Advantageously and according to the invention, the projection of the opening is a substantially vertical cylindrical wall, that is to say substantially orthogonal to the main face of the receiving plane.

Selon l'invention, il est possible d'envisager une légère protubérance faisant saillie du ressaut de sorte à engendrer un clipsage par effet de cliquet venant renforcer le clipsage par frottement et éventuellement le clipsage par effet de coin.According to the invention, it is possible to envisage a slight protuberance projecting from the projection so as to generate clipping by ratchet effect reinforcing the clipping by friction and possibly clipping by wedge effect.

Il est à noter que le procédé selon l'invention peut faire intervenir à titre de moyens de clipsage par effet de cliquet, d'une part, une structure du ressaut en légère contredépouille, c'est-à-dire de forme tronconique de sommet vers le haut, et d'autre part, un bord supérieur de la vasque de chant conjugué de la contredépouille du ressaut.It should be noted that the method according to the invention can be used as clipping means by ratchet effect, on the one hand, a structure of the jump slightly backward, that is to say frustoconical shape of vertex upwards, and on the other hand, an upper edge of the conjugate neck basin of the counterpunch of the projection.

Avantageusement et selon l'invention, le ressaut de l'ouverture et la surface du plan récepteur forme un arrondi à leur jonction. On entend ici par arrondi, un raccordement arrondi en quart de cercle convexe entre deux surfaces. Cet arrondi facilite la mise en place du bord supérieur de la vasque en amorçant son insertion.Advantageously and according to the invention, the projection of the opening and the surface of the receiving plane form a rounded at their junction. Here is meant by rounding, a rounded convex quarter-circle connection between two surfaces. This rounding facilitates the establishment of the upper edge of the basin by initiating its insertion.

Selon un mode de mise en oeuvre préféré, contribuant à l'obtention d'un ensemble monobloc plan récepteur-vasque de bonne cohésion, l'ouverture du plan récepteur présente dans sa partie basse au moins une butée faisant saillie du chant de ladite ouverture, et venant en contact avec l'embouchure de la vasque lorsque celle-ci est mise en place.According to a preferred embodiment, contributing to obtaining a unit monobloc plan receiver-basin of good cohesion, the opening of the receiving plane has in its lower part at least one stop projecting from the edge of said opening, and coming into contact with the mouth of the basin when it is put in place.

Avantageusement et selon l'invention, ladite butée vient au contact de la vasque au niveau de sa portion arrondie de direction centrifuge.Advantageously and according to the invention, said stop comes into contact with the basin at its rounded portion of centrifugal direction.

Avantageusement et selon l'invention, la butée présente une forme convexe conjuguée de la portion arrondie de la vasque.Advantageously and according to the invention, the stop has a conjugate convex shape of the rounded portion of the basin.

Avantageusement et selon l'invention, on interpose dans la zone de contact définie par la butée de l'ouverture du plan récepteur et la portion arrondie de la vasque un joint d'étanchéité.Advantageously and according to the invention is interposed in the contact zone defined by the stop of the opening of the receiving plane and the rounded portion of the basin a seal.

Avantageusement et selon l'invention, la vasque peut être constituée en matière thermoplastique et réalisée par thermoformage ; l'embouchure périphérique de la vasque est alors formée par une extension périphérique qui est ensuite usinée pour réaliser le bord supérieur de l'embouchure selon des dimensions prédéfinies. Selon un mode de mise en oeuvre préféré, la vasque est moulée en matière acrylique et le diamètre radial hors tout du chant de la vasque au repos est de 0,08 % à 0,2 % supérieur au diamètre radial du ressaut.Advantageously and according to the invention, the basin may be made of thermoplastic material and made by thermoforming; the peripheral mouth of the basin is then formed by a peripheral extension which is then machined to make the upper edge of the mouth according to predefined dimensions. According to a preferred embodiment, the basin is molded in acrylic material and the overall radial diameter of the edge of the basin at rest is 0.08% to 0.2% greater than the radial diameter of the projection.

D'autres matières synthétiques rigides ayant des propriétés de déformation élastique peuvent être également utilisées dans la réalisation d'une vasque selon l'invention. La plage de valeurs précédemment définie sera alors à adapter en fonction de l'élasticité de la matière choisie.Other rigid synthetic materials having elastic deformation properties can also be used in the production of a basin according to the invention. The previously defined range of values will then be adapted according to the elasticity of the chosen material.

La vasque peut également être fabriquée par injection dans un moule la conformant directement aux formes prédéfinies.The basin can also be manufactured by injection into a mold conforming directly to the predefined shapes.

Avantageusement et selon l'invention, le plan récepteur est en aggloméré à base de bois, surmonté d'un revêtement de polymère de type chlorure de polyvinyle.Advantageously and according to the invention, the receiving plane is wood-based chipboard, surmounted by a polyvinyl chloride-type polymer coating.

Avantageusement, une vasque d'un ensemble selon l'invention est réalisée en une matière thermoplastique par thermoformage suivi d'un usinage de son embouchure en vue de réaliser le bord supérieur aux formes et aux dimensions prédéfinies.Advantageously, a basin of an assembly according to the invention is made of a thermoplastic material by thermoforming followed by machining of its mouth in order to achieve the upper edge of the shapes and predefined dimensions.

L'invention s'étend enfin, en tant que produit nouveau, à un ensemble monobloc plan récepteur-vasque pour meuble, en particulier de salle de bains ou de cuisine, obtenu par la mise en oeuvre du procédé selon l'invention.Finally, the invention extends, as a new product, to a monobloc plan receptacle-basin unit for furniture, in particular bathroom or kitchen, obtained by the implementation of the method according to the invention.

Un ensemble monobloc plan récepteur-vasque selon l'invention comprend donc une vasque d'une matière synthétique rigide avec une embouchure périphérique comportant une portion évasée vers le haut suivie d'une portion arrondie selon une direction centrifuge se terminant par un chant de formels et dimensions radiales hors tout prédéfinies, intégrée dans un plan récepteur au niveau d'une ouverture présentant sur chant, dans sa partie haute, un ressaut supérieur, caractérisé en ce que la vasque est intégrée au plan récepteur par un clipsage réalisé par le contact entre de la vasque et le ressaut.

Other features, objects and advantages of the invention will become apparent from the description which follows with reference to the accompanying drawings, which show by way of non-limiting example a mode of implementation of the method; in these drawings:
  • the figure 1 schematizes, in section, a basin in the process of thermoforming,
  • the figure 2 is a detail section, on an enlarged scale, of the basin obtained, illustrating the machining operation of its peripheral mouth,
  • the figure 3 schematizes, in section, a receiving plane after machining the opening,

  • the Figures 8 and 9 are detailed views, on an enlarged scale, illustrating an alternative embodiment in which the establishment of a basin in the opening of a receiving plane is by a clipping effect.

L'opération de thermoformage schématisée à titre d'exemple à la figure 1 est en elle-même classique. Une plaque en matière acrylique 9 est mise en forme par une pression pneumatique dans un moule 10 présentant une forme conjuguée de celle de la vasque 1 à obtenir, telle que décrite plus loin. En bordure périphérique, la vasque comporte une extension plane qui est pincée entre moule et contre-moule pendant l'opération de thermoformage.The thermoforming operation shown schematically as an example in figure 1 is in itself classic. An acrylic plate 9 is shaped by pneumatic pressure in a mold 10 having a shape conjugate to that of the bowl 1 to be obtained, as described below. At the peripheral edge, the basin has a flat extension which is clamped between the mold and the counter-mold during the thermoforming operation.

La vasque comprend un fond de type classique (généralement percé d'un trou d'évacuation) et un flanc périphérique qui possède une embouchure composée comme l'illustre la figure 2, d'une portion évasée vers le haut 3, en l'exemple de forme sensiblement tronconique, d'une portion arrondie 4 orientée vers l'extérieur et se terminant par un bord supérieur de direction centrifuge. Ce bord est prolongé par l'extension plane laquelle s'étend selon une direction horizontale (c'est-à-dire orthogonale à l'axe de la vasque).The basin comprises a conventional bottom (usually pierced with a drain hole) and a peripheral flank which has a composite mouth as illustrated by figure 2 , an upwardly flared portion 3, in the example of substantially frustoconical shape, a rounded portion 4 facing outwardly and ending with an upper edge of centrifugal direction. This edge is extended by the plane extension which extends in a horizontal direction (that is to say orthogonal to the axis of the basin).

Après refroidissement, la vasque est usinée sur machine à commande numérique pour découper l'extension et réaliser le bord supérieur de forme et de diamètre précis. Cette découpe est opérée de sorte que le bord ait un chant 5 très légèrement tronconique de sommet vers le bas et d'angle solide α de l'ordre de 10° (la figure 2 étant une représentation à échelle dilatée, l'angle solide α y-est représenté de manière exagérée). Le diamètre médian hors tout du chant 5 mesurant en l'exemple entre 360,03 et 360,07 mm. Bien entendu, d'autres types de moulage (injection...) peuvent être utilisés pour obtenir une telle vasque.After cooling, the basin is machined on a CNC machine to cut the extension and realize the upper edge of precise shape and diameter. This cut is made so that the edge has a very slightly frustoconical edge 5 from top to bottom and a solid angle α of the order of 10 ° (the figure 2 being a dilated representation, the solid angle α y-is exaggerated). The overall median diameter of the edge 5 measuring in the example between 360.03 and 360.07 mm. Of course, other types of molding (injection ...) can be used to obtain such a basin.

Le plan récepteur 2 schématisé aux figures 3 et 4, est un panneau en tout matériau habituellement utilisé dans ce type d'application (matériau composite, bois, lamellé collé, marbre, granit...). En l'exemple représenté, ce panneau est en aggloméré à base de bois, revêtu d'un revêtement décoratif en chlorure de polyvinyle dont la surface 2a constituera la surface supérieure apparente du produit fini.The receiver plane 2 diagrammatically Figures 3 and 4 , is a panel of any material usually used in this type of application (composite material, wood, glulam, marble, granite ...). In the example shown, this panel is wood-based chipboard, coated with a decorative polyvinyl chloride coating whose surface 2a will be the apparent upper surface of the finished product.

Ce panneau est percé de part en part et soumis à un usinage sur machine numérique en vue de ménager dans celui-ci une ouverture 6 dont le chant périphérique possède, comme l'illustre la figure 4, un ressaut supérieur 7 de 360 mm de diamètre, une butée 8 faisant saillie dans la partie basse de l'ouverture, usinée pour venir au contact de la portion arrondie 4 de la vasque 1.This panel is pierced from one end to the other and subjected to machining on a digital machine in order to provide therein an opening 6 whose peripheral edge has, as illustrated by FIG. figure 4 , an upper projection 7 360 mm in diameter, a stop 8 projecting into the lower part of the opening, machined to come into contact with the rounded portion 4 of the basin 1.

Les figures 5 et 6 illustrent l'opération de mise en place de la vasque 1 dans l'ouverture 6 du plan récepteur 2. La vasque est positionnée au-dessus de l'ouverture 6 du plan récepteur 2 de façon que son chant vienne au contact de la portion supérieure du ressaut. On exerce sur la vasque une force d'insertion vers le bas adaptée pour déformer élastiquement le chant 5 de la vasque 1 et réaliser le clipsage.The Figures 5 and 6 illustrate the setting operation of the basin 1 in the opening 6 of the receiving plane 2. The basin is positioned above the opening 6 of the receiving plane 2 so that its song comes into contact with the upper portion of the jump. On the basin is exerted a downward insertion force adapted to elastically deform the edge 5 of the basin 1 and perform the clipping.

Au terme de ces opérations, on obtient un ensemble monobloc, plan récepteur-vasque tel qu'illustré à la figure 7. Cet ensemble bénéficie d'une qualité d'aspect remarquable, ne nécessitant pour son assemblage ni soudure ni colle, mais qui toutefois, de part un clipsage particulier, permet une excellente cohésion entre vasque 1 et plan récepteur 2 avec un positionnement parfait de la vasque 1 par rapport au plan récepteur 2, ainsi qu'une bonne étanchéité.At the end of these operations, we obtain a monobloc assembly, sink-receiver plane as illustrated in FIG. figure 7 . This set has a remarkable quality of appearance, requiring for its assembly neither solder nor glue, but which, by a particular clipping, allows an excellent cohesion between sink 1 and receiver plane 2 with a perfect positioning of the basin 1 relative to the receiving plane 2, as well as a good seal.

Les figures 8 et 9 illustrent une autre variante de réalisation dans laquelle la cohésion entre le plan récepteur 2 et la vasque 1 est obtenue par un clipsage de type clipsage par effet de cliquet. En l'exemple représenté, le plan récepteur 2 présente une ouverture de ressaut supérieur 7', très légèrement incliné en contredépouille (c'est-à-dire de forme tronconique de sommet vers le haut) et la vasque 1 présente un bord supérieur de chant 5' conjugué du ressaut supérieur 7'. Les angles β et β', tels que représentés à la figure 8 et qui définissent respectivement l'inclinaison du ressaut 7' et celle du chant 5' sont sensiblement égaux. Des angles β et β' même très faibles, de l'ordre du degré, suffisent pour réaliser ce type de clipsage par effet de cliquet.The Figures 8 and 9 illustrate another alternative embodiment in which the cohesion between the receiving plane 2 and the basin 1 is obtained by clipping type clipping effect. In the example shown, the receiving plane 2 has an upper aperture opening 7 ', very slightly inclined in counterpulp (that is to say of frustoconical shape from top to top) and the basin 1 has an upper edge of 5 'conjugate singing of the upper projection 7'. The angles β and β ', as represented in figure 8 and who define respectively the inclination of the projection 7 'and that of the edge 5' are substantially equal. Even very small angles β and β ', of the order of a degree, are sufficient to achieve this type of clipping by ratchet effect.

L'opération de mise en place de la vasque 1 de l'ouverture du plan récepteur 2 est, dans le cas présent, comparable à celle décrite précédemment (figures 5 et 6). On positionne la vasque 1 au-dessus de l'ouverture 6 du plan récepteur 2 de façon que son chant 5' vienne au contact de la portion supérieure du ressaut 7'. On exerce alors sur la vasque une force d'insertion vers le bas de manière à obtenir une déformation élastique conduisant au clipsage par effet de cliquet de la vasque 1 dans le plan récepteur 2.The operation of setting up the vessel 1 of the opening of the receiving plane 2 is, in this case, comparable to that described previously ( Figures 5 and 6 ). The basin 1 is positioned above the opening 6 of the receiving plane 2 so that its edge 5 'comes into contact with the upper portion of the projection 7'. A downward insertion force is then exerted on the basin so as to obtain an elastic deformation leading to clipping of the basin 1 in the receiving plane 2 by the ratchet effect.

Bien que les figures ne le montrent pas, il est à noter que ce type de clipsage par effet de cliquet, qui fait intervenir une structure en contredépouille, peut permettre l'obtention d'un affleurement de la vasque au niveau de la surface supérieure du plan récepteur.Although the figures do not show it, it should be noted that this type of ratchet clipping, which involves an undercut structure, may allow to obtain a flush of the basin at the upper surface of the receiving plane.
