Description détaillée de l'inventionDetailed description of the invention

La présente invention concerne un composant d'habillage 10 d'une montre ou d'un article de bijouterie ou de joaillerie tel que représenté sur les figures 3 et 4 dans des exemples de réalisation, et tel que représenté, lors d'étapes de sa fabrication, sur les figures 1 et 2.The present invention relates to a trim component 10 of a watch or an article of jewelery or jewelery as shown in the figures 3 and 4 in exemplary embodiments, and as shown, during stages of its manufacture, on the figures 1 and 2 .

Le composant d'habillage 10 comprend un substrat 11 réalisé dans un matériau transparent, tel qu'en saphir ou en verre. Le substrat 11 comporte une face interne 110 opposée à une face externe 111 depuis laquelle un utilisateur est destiné à voir un décor du composant d'habillage 10, à travers ledit substrat 11. Plus particulièrement, la face externe 111 est destinée à être orientée vers un environnement extérieur et la face interne 110 est destinée à être orientée vers un environnement intérieur, par exemple en regard d'un mouvement horloger, dans le cas dans lequel le composant d'habillage 10 est un composant d'une montre.The dressing component 10 comprises a substrate 11 made of a transparent material, such as sapphire or glass. The substrate 11 comprises an internal face 110 opposite an external face 111 from which a user is intended to see a decoration of the covering component 10, through said substrate 11. More particularly, the external face 111 is intended to be oriented towards an external environment and the internal face 110 is intended to be oriented towards an internal environment, for example facing a watch movement, in the case in which the covering component 10 is a component of a watch.

Le composant d'habillage 10 comprend une couche de base 12 déposée sur une première portion de la face interne 110 et au moins une couche secondaire 13 déposée sur la couche de base 12 et sur une seconde portion de la face interne 110 non recouverte par ladite couche de base 12. Comme le montrent les figures 3 et 4, la première et la seconde portion de la face interne 110 sont contiguës l'une à l'autre.The covering component 10 comprises a base layer 12 deposited on a first portion of the inner face 110 and at least one secondary layer 13 deposited on the base layer 12 and on a second portion of the inner face 110 not covered by said base coat 12. As shown in the figures 3 and 4 , the first and the second portion of the inner face 110 are contiguous to one another.

Avantageusement, la première et la seconde portion de la face interne 110 présentent des états de surface différents l'une de l'autre.Advantageously, the first and the second portion of the inner face 110 have different surface states from each other.

En particulier, la première portion de la face interne 110 est préférentiellement polie, et la seconde portion de la face interne 110 présente préférentiellement au moins une structuration 112. Dans la présente description de l'invention, il est fait référence ci-dessous à une seule structuration 112 pour faciliter la lecture. La notion de « structuration » définit ici une surface dont la topographie a été modifiée et celle-ci peut consister en un satinage, une texturation, une gravure, etc. La combinaison entre la couche de base 12, la couche secondaire 13 et les différents états de surface forme avantageusement un décor particulièrement attractif.In particular, the first portion of the inner face 110 is preferably polished, and the second portion of the inner face 110 preferably has at least one structuring 112. In the present description of the invention, reference is made below to a only structuring 112 to facilitate reading. The notion of “structuring” here defines a surface whose topography has been modified and this may consist of satin-finishing, texturing, engraving, etc. The combination between the base layer 12, secondary layer 13 and the different surface states advantageously form a particularly attractive decoration.

La couche de base 12 et la couche secondaire 13 présentent préférentiellement des compositions différentes l'une de l'autre. Elles peuvent être réalisées en tout matériau approprié, par exemple en métal, tel qu'en chrome, en or, en titane, en zirconium, etc., ou en céramique. Ces couches peuvent également être constituées, l'une et/ou l'autre, par un empilement de couches minces, de façon connue en soi par l'homme du métier.The base layer 12 and the secondary layer 13 preferably have different compositions from each other. They can be made of any suitable material, for example metal, such as chromium, gold, titanium, zirconium, etc., or ceramic. These layers can also be formed, one and/or the other, by a stack of thin layers, in a manner known per se by those skilled in the art.

Ce composant d'habillage 10 forme préférentiellement un cadran ou un réhaut de montre.This covering component 10 preferably forms a watch dial or flange.

Par ailleurs, ce composant d'habillage 10 est préférentiellement réalisé par un procédé de fabrication dont les étapes sont représentées de manière chronologique par les figures 1 à 3 et éventuellement 1 à 4 dans un autre exemple de mise en œuvre.Furthermore, this trim component 10 is preferably produced by a manufacturing process whose stages are represented chronologically by the figures 1 to 3 and optionally 1 to 4 in another exemplary implementation.

Plus particulièrement, le procédé de fabrication comprend une première étape de dépôt de la couche de base 12 sur l'ensemble de la surface de la face interne 110 du substrat 11, tel que représenté sur la figure 1.More particularly, the manufacturing method comprises a first step of depositing the base layer 12 on the entire surface of the internal face 110 of the substrate 11, as represented on the figure 1 .

Un tel dépôt peut être réalisé par méthode de dépôt physique par phase vapeur, de dépôt chimique par phase vapeur, ou par toute autre méthode appropriée.Such a deposition can be carried out by physical vapor deposition method, chemical vapor deposition method, or by any other appropriate method.

Préférentiellement, la face interne 110 est polie lors d'une étape préliminaire de polissage, préalablement au dépôt de la couche de base 12.Preferably, the inner face 110 is polished during a preliminary polishing step, prior to the deposition of the base layer 12.

Le procédé comporte par la suite une étape d'ablation localisée de la couche de base 12, tel que représenté par la figure 2, de sorte à former une ou des poches 14 débouchant sur la face interne 110 du substrat 11 et, dans le même temps, à structurer ladite face interne 110 au niveau de la ou de chacune des poches 14 afin de réaliser une structuration 112.The method then comprises a step of localized ablation of the base layer 12, as represented by the picture 2 , so as to form one or more pockets 14 opening onto the internal face 110 of the substrate 11 and, at the same time, to structure said internal face 110 at the level of the or each of the pockets 14 in order to achieve a structuring 112.

Plus particulièrement, à l'issue de l'étape d'ablation localisée, la partie de la couche de base 12 non impactée par l'ablation repose contre une première portion de la face interne 110 du substrat 11, les poches 14 débouchent sur une seconde portion de la face interne 110 du substrat 11, et ladite seconde portion de la face interne 110 est structurée. Ainsi, la ou chaque structuration 112 coïncide parfaitement avec la poche 14 avec laquelle elle est générée.More particularly, at the end of the localized ablation step, the part of the base layer 12 not impacted by the ablation rests against a first portion of the internal face 110 of the substrate 11, the pockets 14 open onto a second portion of the inner face 110 of the substrate 11, and said second portion of the inner face 110 is structured. Thus, the or each structuring 112 coincides perfectly with the pocket 14 with which it is generated.

L'ablation locale de la couche de base 12, et par voie de conséquence, la ou les structurations 112 de la seconde portion de la face interne 110, est préférentiellement réalisée par faisceau laser. Alternativement, l'étape d'ablation locale peut être réalisée par gravure robotisée avec une pointe diamant, par usinage mécanique, chimique, etc.The local ablation of the base layer 12, and consequently, the structuring(s) 112 of the second portion of the internal face 110, is preferably carried out by laser beam. Alternatively, the local ablation step can be performed by robotic engraving with a diamond tip, by mechanical or chemical machining, etc.

Une étape de dépôt d'une couche secondaire 13 est par la suite réalisée sur la couche de base 12 et dans les poches 14, c'est-à-dire, sur la seconde portion de la face interne 110 du substrat 11, de sorte à obtenir un composant d'habillage 10 comme visible sur la figure 3. Le respect des tolérances d'alignement de la couche de base 12 et de la couche secondaire 13 avec la première et la seconde portion de la face interne 110 présentant des états de surface différents est donc assuré.A step of depositing a secondary layer 13 is then carried out on the base layer 12 and in the pockets 14, that is to say, on the second portion of the internal face 110 of the substrate 11, so to obtain a covering component 10 as seen on the picture 3 . Compliance with the alignment tolerances of the base layer 12 and of the secondary layer 13 with the first and the second portion of the internal face 110 having different surface states is therefore ensured.

On note que, grâce aux caractéristiques de l'invention, l'aspect visuel du décor du composant d'habillage 10 peut être particulièrement attractif dans la mesure où au contraste entre la possible différence de couleurs de la couche de base 12 et de la couche secondaire 13, s'ajoute le contraste entre les différents états de surface des portions de la face interne 110 sur lesquelles lesdites couches sont respectivement déposées.It is noted that, thanks to the characteristics of the invention, the visual appearance of the decoration of the covering component 10 can be particularly attractive insofar as the contrast between the possible difference in colors of the base layer 12 and of the layer secondary 13, is added the contrast between the different surface states of the portions of the inner face 110 on which said layers are respectively deposited.

Le dépôt de la couche secondaire 13 peut également être réalisé par méthode de dépôt physique par phase vapeur, de dépôt chimique par phase vapeur, ou par toute autre méthode appropriée.The deposition of the secondary layer 13 can also be carried out by physical vapor deposition method, chemical vapor deposition method, or by any other appropriate method.

Enfin, le procédé peut comporter une étape finale de gravure dans laquelle une partie de la couche de base 12 et une partie de la couche secondaire 13 sont retirées de sorte à conformer lesdites couches selon une forme prédéfinie, sans que le substrat 11 ne soit impacté, tel que le représente la figure 4.Finally, the method may include a final etching step in which part of the base layer 12 and part of the layer 13 are removed so as to form said layers according to a predefined shape, without the substrate 11 being impacted, as shown in the figure 4 .

Une telle étape finale de gravure peut être mise en œuvre par photolithographie, usinage laser, etc.Such a final etching step can be implemented by photolithography, laser machining, etc.

De manière plus générale, il est à noter que les modes de mise en œuvre et de réalisation considérés ci-dessus ont été décrits à titre d'exemples non limitatifs, et que d'autres variantes sont par conséquent envisageables.More generally, it should be noted that the modes of implementation and embodiment considered above have been described by way of non-limiting examples, and that other variants are therefore possible.

Notamment, le procédé de fabrication peut comporter une autre étape d'ablation localisée afin de réaliser une ou des poches traversant la couche de base 12 et la couche secondaire 13 jusqu'à déboucher sur une portion de la face interne 110 du substrat 11, et dans le même temps, de structurer ladite portion de la face interne 110. A la suite de cette autre étape d'ablation localisée, une troisième couche peut être déposée sur la couche secondaire 13 et dans la ou lesdites poches, de manière analogue à l'étape de dépôt de la couche secondaire 13.In particular, the manufacturing process may include another step of localized ablation in order to produce one or more pockets passing through the base layer 12 and the secondary layer 13 until they emerge on a portion of the internal face 110 of the substrate 11, and at the same time, to structure said portion of the internal face 110. Following this other localized ablation step, a third layer can be deposited on the secondary layer 13 and in the said pocket or pockets, in a manner analogous to the step of depositing the secondary layer 13.

De manière générale, il est envisageable que le procédé comporte autant d'étapes d'ablation localisée, chacune suivie d'une étape de dépôt d'une couche supplémentaire, que nécessaire, selon le décor souhaité.Generally, it is possible for the method to include as many localized ablation steps, each followed by a step of depositing an additional layer, as necessary, depending on the desired decoration.
