Description

L'invention se rapporte à un procédé de décoration d'articles, ainsi qu'aux articles décorés selon le procédé. Elle se rapporte plus particulièrement aux articles se présentant sous la forme de stratifiés regroupant différents matériaux plastiques et composites, tels que les engins de glisse ou de roulage. Ces engins peuvent être des skis, des planches de surf sur neige ou snowboard, des planches à roulettes, des planches à eau ou autre.The invention relates to a method of decorating articles, as well as articles decorated according to the method. It relates more particularly to articles in the form of laminates comprising various plastic materials and composites, such as gliding or rolling machines. These machines can be skis, surfboards on snow or snowboard, skateboards, water boards or other.

La structure d'un ski ou d'une planche est généralement formée par la superposition d'une semelle de glisse, d'un premier renfort, d'un noyau, d'un deuxième renfort, et d'un complexe de décoration. Ce dernier comprend une feuille de protection, sur une face interne de laquelle est déposée une couche de décoration. La feuille de protection est transparente ou translucide de façon à laisser voir la couche de décoration, tout en protégeant la couche des agressions mécaniques, chimiques ou autres. Un tel procédé est connu de EP-A 0850785 .The structure of a ski or a board is generally formed by the superposition of a gliding sole, a first reinforcement, a core, a second reinforcement, and a decorative complex. The latter comprises a protective sheet, on an inner side of which is deposited a decorative layer. The protective sheet is transparent or translucent so as to show the decorative layer, while protecting the layer from mechanical, chemical or other aggression. Such a method is known to EP-A 0850785 .

Le complexe de décoration est solidarisé au deuxième renfort, lors de l'assemblage des pièces constitutives du ski ou de la planche, par augmentation de température et de pression. Le complexe épouse la forme donnée au ski ou à la planche. L'assemblage ne modifie pas la couche de décoration, cette dernière étant maintenue sur la face interne de la feuille de protection. Ainsi l'esthétique de l'article est directement corrélée à l'esthétique initiale de la couche de décoration. En d'autres termes un observateur a sensiblement la même perception visuelle de la couche de décoration avant ou après l'assemblage.The decoration complex is secured to the second reinforcement, during assembly of the component parts of the ski or the board, by increasing temperature and pressure. The complex follows the shape given to the ski or the board. The assembly does not modify the decorative layer, the latter being maintained on the inner face of the protective sheet. Thus the aesthetics of the article is directly correlated to the initial aesthetics of the decorative layer. In other words, an observer has substantially the same visual perception of the decorative layer before or after assembly.

L'invention a notamment pour but de modifier l'effet esthétique apporté par la couche de décoration avant l'assemblage.The invention is intended in particular to modify the aesthetic effect provided by the decorative layer before assembly.

Pour cela l'invention propose un procédé de décoration d'un article, le procédé comprenant la préparation d'un complexe destiné à être apposé à l'article ou à en faire partie intégrante, une étape première du procédé consistant à déposer une couche de décoration sur une face interne d'une feuille de protection du complexe, la feuille de protection étant transparente ou translucide, caractérisé par le fait que la feuille de protection est fluable à chaud, et par le fait qu'une étape postérieure du procédé comprend la disposition d'une couche de matériau ajouré en dessous de la couche de décoration, puis une élévation de température et de pression, de façon que la couche de matériau ajouré s'incruste en partie au moins dans la feuille de protection, la couche de décoration épousant la forme de la couche de matériau ajouré.For this purpose the invention proposes a method for decorating an article, the method comprising the preparation of a complex intended to be affixed to the article or to be an integral part thereof, a first step in the process of depositing a layer of decoration on an inner face of a protective sheet of the complex, the protective sheet being transparent or translucent, characterized in that the protective sheet is heat-flowable, and in that a subsequent step of the process comprises the disposing a layer of perforated material below the decorative layer, then raising the temperature and pressure, so that the layer of perforated material is partially embedded in at least the protective sheet, the decorative layer marrying the shape of the layer of perforated material.

Ce procédé modifie la couche de décoration dans le sens où certaines portions de la couche restent au niveau de la face interne de la feuille de protection, alors que d'autres portions de la couche pénètrent à l'intérieur de la feuille au-delà de la face interne. Le procédé donne à la couche de décoration un relief qui est très perceptible visuellement. Le relief est rendu encore plus perceptible si la couche de décoration présente un aspect métallisé, nacré, irisé, moiré, variochromatique ou brillant.This process modifies the decorative layer in the sense that some portions of the layer remain at the inner face of the protective sheet, while other portions of the layer penetrate the interior of the sheet beyond the internal face. The process gives the decoration layer a relief that is very visually perceptible. The relief is made even more noticeable if the decorative layer has a metallized, pearly, iridescent, moiré, variochromatic or shiny appearance.

En d'autres termes le procédé selon l'invention modifie l'effet esthétique apporté par la couche de décoration avant que le complexe ne soit réalisé, par un effet de relief supplémentaire. Bien entendu, la texture de la couche de matériau ajouré est choisie selon l'effet recherché.In other words, the process according to the invention modifies the aesthetic effect provided by the decorative layer before the complex is produced by a relief effect. additional. Of course, the texture of the layer of openwork material is chosen according to the desired effect.

Bien que la description ci-après concerne un procédé de décoration d'une planche de glisse ou de roulage, il doit être compris qu'elle a trait également à d'autres articles, notamment des articles de sport.Although the following description relates to a method of decorating a gliding or rolling board, it should be understood that it also relates to other articles, including sports articles.

Le premier exemple de réalisation de l'invention est présenté à l'aide des figures 1 à 3.The first embodiment of the invention is presented using the Figures 1 to 3 .

Le procédé de décoration comprend la préparation d'un complexe 1, destiné à être apposé à l'article ou à en faire partie intégrante.The decoration process comprises the preparation of a complex 1, intended to be affixed to the article or to be an integral part thereof.

De manière connue, le complexe 1 comprend notamment une feuille de protection 2 et une couche de décoration 3.In known manner, the complex 1 comprises in particular a protective sheet 2 and a decorative layer 3.

La feuille de protection 2 s'étend en épaisseur entre une face externe 4 et une face interne 5. L'épaisseur de la feuille de protection 2 est de préférence comprise entre 0,2 et 2 mm.The protective sheet 2 extends in thickness between an outer face 4 and an inner face 5. The thickness of the protective sheet 2 is preferably between 0.2 and 2 mm.

La feuille de protection 2 peut être réalisée à partir d'un Acrylonitrile Butadiène Styrène ou d'un Acrylonitrile Styrène mélangé ou non à un élastomère thermoplastique uréthane, ou bien à partir d'un polyamide, d'un polycarbonate, d'un polyéthylène téréphtalate, ou autre.The protective film 2 may be made from Acrylonitrile Butadiene Styrene or Acrylonitrile Styrene mixed or not with a thermoplastic urethane elastomer, or from a polyamide, a polycarbonate, a polyethylene terephthalate , Or other.

Une première étape du procédé consiste à déposer la couche de décoration 3 sur la face interne 5 de la feuille de protection 2. Cette dernière est transparente ou translucide. Ainsi la couche de décoration 3 est à la fois visible par l'observateur et protégée des agressions extérieures, telles que les agressions mécaniques, chimiques ou autres.A first step of the method consists of depositing the decorative layer 3 on the inner face 5 of the protective sheet 2. The latter is transparent or translucent. Thus the decorative layer 3 is both visible to the observer and protected from external aggression, such as mechanical, chemical or other aggression.

La couche de décoration 3 est formée par exemple à partir d'encres et / ou de peintures. Celles-ci sont déposées par exemple selon des techniques telles que la sérigraphie, la projection sous pression par pistolet, le passage sous un rideau à encre ou à peinture, l'application au rouleau ou au pinceau ou toute technique équivalente.The decorative layer 3 is formed for example from inks and / or paints. These are deposited for example by techniques such as screen printing, spray gun pressure, passage under an ink curtain or paint, application by roller or brush or any equivalent technique.

L'épaisseur de la couche de décoration 3 est de préférence comprise entre quelques microns et quelques dixièmes de millimètres.The thickness of the decorative layer 3 is preferably between a few microns and a few tenths of a millimeter.

Selon l'invention la couche de décoration 3 présente de préférence un aspect métallisé, nacré, irisé, moiré, variochromatique ou brillant. Cet aspect est obtenu parce que les encres ou les peintures contiennent par exemple de la poudre de métal ou de sel métallique, de la poudre de nacre, des pigments variochromatiques ou tout matériau équivalent.According to the invention, the decorative layer 3 preferably has a metallic, pearlescent, iridescent, moiré, variochromatic or glossy appearance. This aspect is achieved because the inks or paints contain, for example, metal powder or metal salt, mother-of-pearl powder, variochromatic pigments or any equivalent material.

Une étape postérieure du procédé, selon l'invention, comprend la disposition d'une couche de matériau ajouré 10 en dessous de la couche de décoration 3. En d'autres termes la couche de matériau ajouré 10 et la feuille de protection 2 sont situées respectivement de part et d'autre de la couche de décoration 3.A subsequent step of the method according to the invention comprises the arrangement of a layer of perforated material 10 below the decorative layer 3. In other words the layer of perforated material 10 and the protective sheet 2 are located respectively on both sides of the decorative layer 3.

La couche de matériau ajouré 10 est représentée sous la forme d'une grille souple réalisée par exemple avec des fibres de verre 11. Les ouvertures 12 de la grille 10 ont ici une forme sensiblement carrée. Les fibres peuvent avoir une section comprise par exemple entre 0,01 et 5 mm2. Le côté du carré de l'ouverture peut varier par exemple entre 1 et 30 mm, une valeur préférée étant comprise entre 5 et 10 mm.The layer of perforated material 10 is represented in the form of a flexible grid made for example with glass fibers 11. The openings 12 of the grid 10 here have a substantially square shape. The fibers may have a cross-section of, for example, between 0.01 and 5 mm 2 . The side of the square of the opening may vary for example between 1 and 30 mm, a preferred value being between 5 and 10 mm.

Cependant il doit être comprise que le matériau ajouré pourrait présenter des ouvertures de toutes formes telles que de rectangles, des losanges, des triangles, des hexagones ou autres. Les ouvertures peuvent être réparties de façon régulière ou irrégulière. Les ouvertures 12 couvrent une surface plus importante que la surface couverte par le matériau constitutif de la couche ajourée 10. De nombreux matériaux peuvent être utilisés pour la couche ajourée, comme le carbone, l'aramide, un métal, une matière plastique, de la ficelle ou autre.However it should be understood that the openwork material could have openings of any shape such as rectangles, rhombuses, triangles, hexagons or others. The openings can be distributed evenly or irregularly. The openings 12 cover a larger area than the surface covered by the material constituting the perforated layer 10. Many materials can be used for the perforated layer, such as carbon, aramid, a metal, a plastic, string or other.

La feuille de protection 2 est fluable à chaud. L'étape postérieure du procédé comprend une élévation de température et de pression, dé façon que la couche de matériau ajouré 10 s'incruste en partie au moins dans la feuille de protection 2. La couche de décoration 3 épouse alors la forme de la couche de matériau ajouré 10, comme le montre la figure 3. La température peut être de l'ordre de 80 à 100°C si la feuille de protection comprend un mélange d'Acrylonitrile Butadiène Styrène et d'élastomère thermoplastique uréthane. La pression peut être de quelques bars ou de quelques dizaines de bars.The protective sheet 2 is heat-flowable. The subsequent step of the process comprises a rise in temperature and pressure, so that the layer of perforated material 10 is at least partly embedded in the protective sheet 2. The decorative layer 3 then conforms to the shape of the layer of perforated material 10, as shown in FIG. figure 3 . The temperature may be of the order of 80 to 100 ° C if the protective sheet comprises a mixture of acrylonitrile butadiene styrene and thermoplastic urethane elastomer. The pressure can be a few bars or a few dozen bars.

Le complexe 1, qui au final comprend la feuille de protection 2, la couche de décoration 3 et la couche de matériau ajouré 10, peut être réalisé en tant que tel ou en association avec les autres parties constitutives de l'article décoré.The complex 1, which in the end comprises the protective film 2, the decorative layer 3 and the layer of perforated material 10, can be produced as such or in combination with the other constituent parts of the decorated article.

Dans tous les cas la couche de décoration 3 présente un relief qui est celui du matériau ajouré. Ce relief est très perceptible visuellement par l'observateur, à travers la feuille de protection 2, grâce au fait que la couche de décoration 3 présente un aspect métallisé, nacré, irisé, moiré, variochromatique ou brillant. Il est possible de donner à l'article décoré un aspect visuel en relief mais avec une surface externe régulière, cette surface étant la face externe 4 de la feuille de protection 2.In all cases the decorative layer 3 has a relief which is that of the perforated material. This relief is very visually perceptible by the observer, through the protective sheet 2, thanks to the fact that the decorative layer 3 has a metallic appearance, pearly, iridescent, moiré, variochromatic or glossy. It is possible to give the decorated article an appearance visual relief but with a regular outer surface, this surface being the outer face 4 of the protective sheet 2.

Un avantage qui en découle est une richesse accrue de la décoration, puisqu'on dispose de fait de deux éléments de décoration à savoir la couche de décoration et la couche de matériau ajouré, alliée à une facilité d'entretien de l'article. En effet, une face régulière se nettoie facilement.An advantage that arises is an increased wealth of decoration, since it has in fact two decorative elements namely the decorative layer and the layer of openwork material, combined with ease of maintenance of the article. Indeed, a regular face is easy to clean.

Les autres exemples de réalisation de l'invention sont présentés après à l'aide des figures 4 à 9. Pour des raisons de commodité, ce sont essentiellement les différences par rapport au premier exemple qui sont mises en évidence.The other embodiments of the invention are presented after using the Figures 4 to 9 . For the sake of convenience, it is essentially the differences from the first example that are highlighted.

Le deuxième exemple est présenté à l'aide des figures 4 à 6.The second example is presented using the Figures 4 to 6 .

Un complexe 20 comprend successivement une feuille de protection 21, une couche de décoration 22, une couche de protection 23, une couche de matériau ajouré 24, et un voile 25.A complex 20 successively comprises a protective sheet 21, a decorative layer 22, a protective layer 23, a layer of perforated material 24, and a web 25.

La couche de protection 23 sert d'isolant optique. Elle est de préférence réalisée avec une encre ou une peinture de couleur claire, comme la couleur blanche. Cela évite que la couleur naturelle de l'article soit perçue visuellement à travers la couche de décoration 22.The protective layer 23 serves as optical insulation. It is preferably made with an ink or a light-colored paint, such as white color. This prevents the natural color of the article from being perceived visually through the decorative layer 22.

Le voile 25 quant à lui sert à masquer d'éventuelles aspérités ou petites irrégularités de surface de l'article ou d'une partie structurelle de l'article.The veil 25 is used to hide any asperities or small surface irregularities of the article or a structural part of the article.

Comme on le voit sur la figure 6 le complexe 20 fait partie intégrante d'un article, représenté sous la forme d'une planche de glisse 26 vue en coupe. De bas en haut la planche 26 comprend successivement une semelle de glisse 30, un premier renfort 31, un noyau 32, un deuxième renfort 33, et le complexe 20.As we see on the figure 6 the complex 20 is an integral part of an article, shown in the form of a gliding board 26 sectional view. From bottom to top the board 26 successively comprises a gliding sole 30, a first reinforcement 31, a core 32, a second reinforcement 33, and the complex 20.

De préférence le complexe 20 couvre une partie seulement de la planche 26. Cependant il pourrait être prévu qu'il couvre la totalité de la planche ou au moins la totalité du deuxième renfort 33.Preferably the complex 20 covers only part of the board 26. However it could be expected that it covers the entire board or at least the entire second reinforcement 33.

De préférence la feuille de protection 21 s'étend sensiblement au-dessus de la totalité du deuxième renfort 33.Preferably, the protective sheet 21 extends substantially over the entire second reinforcement 33.

Les éléments constitutifs de la planche 26 sont assemblés de la manière suivante. Lors d'une première étape la couche de décoration 22 est déposée sur une face interne 34 de la feuille de protection 21. Lors d'une étape ultérieure la semelle 30, le premier renfort 31, le noyau 32, le deuxième renfort 33 et le complexe 20 sont empilés dans un moule. Une élévation de température et de pression permet la solidarisation relative des éléments constitutifs de la planche de glisse 26.The constituent elements of the board 26 are assembled in the following manner. In a first step, the decorative layer 22 is deposited on an inner face 34 of the protective sheet 21. In a subsequent step, the sole 30, the first reinforcement 31, the core 32, the second reinforcement 33 and the complex 20 are stacked in a mold. An increase in temperature and pressure allows the relative joining of the components of the gliding board 26.

Bien entendu, l'étape ultérieure pourrait être décomposée en plusieurs étapes successives.Of course, the subsequent step could be broken down into several successive steps.

D'autre part, la planche 26 peut comprendre d'autres éléments tels que des films de collage des couches les unes aux autres. Ces films peuvent être réalisés par exemple à partir d'un copolymère d'éthylène et d'acétate de vinyle, greffé par action d'acide carboxylique ou d'anhydride d'acide carboxylique.On the other hand, the board 26 may comprise other elements such as films for bonding the layers to one another. These films can be made for example from a copolymer of ethylene and vinyl acetate, grafted by the action of carboxylic acid or carboxylic acid anhydride.

Le troisième exemple de réalisation de l'invention est présenté à l'aide des figures 7 et 8.The third embodiment of the invention is presented using the Figures 7 and 8 .

Un complexe de décoration 40 comprend une feuille de protection 41, une couche de décoration 42, et une couche de matériau ajouré 43. Des ouvertures 44 sont ménagées dans la couche de matériau ajouré 43. Les ouvertures 44 ont ici une forme cylindrique, mais elles pourraient avoir d'autres formes. Les ouvertures 44 couvrent une surface moins importante que la surface couverte par le matériau constitutif de la couche ajourée 43.A decorative complex 40 comprises a protective sheet 41, a decorative layer 42, and a layer of perforated material 43. Apertures 44 are formed in the layer of perforated material 43. The openings 44 here have a cylindrical shape, but they could have other forms. The openings 44 cover a smaller area than the surface covered by the constituent material of the perforated layer 43.

Le quatrième exemple de réalisation de l'invention est présenté à l'aide de la figure 9.The fourth embodiment of the invention is presented using the figure 9 .

Un complexe de décoration 50 comprend une feuille de protection 51, une couche de décoration 52,et une couche de matériau ajouré 53. Cette dernière présente une structure irrégulière qui confère au complexe une esthétique originale.A decorative complex 50 comprises a protective sheet 51, a decorative layer 52, and a layer of perforated material 53. The latter has an irregular structure that gives the complex an original aesthetic.

D'une manière générale, l'invention est réalisée à partir de matériaux et selon des techniques connues de l'homme du métier.In general, the invention is made from materials and according to techniques known to those skilled in the art.

Bien entendu, l'invention n'est pas limitée aux exemples ci-avant décrits, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Of course, the invention is not limited to the examples described above, and includes all the technical equivalents that fall within the scope of the claims that follow.

En particulier, les ouvertures des couches ajourées peuvent être traversantes ou non. Une couche ajourée pourrait être réalisée par tissage et avoir l'aspect d'une dentelle ou d'un napperon.In particular, the openings of the perforated layers may be through or not. A perforated layer could be made by weaving and have the appearance of a lace or a placemat.
