Etat de la techniqueState of the art

L'obtention de pierres souples en les combinant (par exemple, par émulsion) avec des élastomères, silicones, polymères est connue de CN102493618 .Obtaining flexible stones by combining them (for example, by emulsion) with elastomers, silicones, polymers is known from CN102493618 .

Le document EP2605893 décrit un procédé pour la préparation d'une pierre flexible avec surface naturelle, comprenant le mélange de mouture de pierre avec un liant flexible.The document EP2605893 describes a process for the preparation of a flexible stone with natural surface, comprising the mixture of ground stone with a flexible binder.

Les pierres flexibles obtenues par les procédés décrits dans ces documents sont cependant destinées à des applications de décoration architecturales et exigent l'ajout d'additifs à la matière de la pierre.The flexible stones obtained by the methods described in these documents are however intended for architectural decoration applications and require the addition of additives to the material of the stone.

L'obtention d'une pierre souple pour une utilisation dans des articles décoratifs tels que des articles de bijouterie, d'horlogerie, de mode, de maroquinerie, etc., serait d'un grand intérêt puisqu'une telle pierre permettrait de conférer à l'article des caractéristiques visuelles et tactiles inédites.Obtaining a flexible stone for use in decorative articles such as jewelry, watches, fashion, leather goods, etc., would be of great interest since such a stone would give the article of new visual and tactile characteristics.

Bref résumé de l'inventionBrief summary of the invention

La présente invention concerne un procédé pour l'obtention, notamment à partir d'une pierre fine ou semi-précieuse, d'une pierre souple et flexible par la microfissuration contrôlée de la pierre.The present invention relates to a process for obtaining, in particular from a fine or semi-precious stone, a flexible and flexible stone by controlled microcracking of the stone.

Selon un mode de réalisation privilégié, la pierre est en premier affinée en lamelle, puis un quadrillage de gorges ou rainures est tracé au laser au verso de la lamelle. Le verso de la lamelle est ensuite fixé (par exemple collé) sur un support souple. Par exemple, un support métallique ou autre avec différents moyens d'adhésion appropriés. L'ensemble (lamelle encollée) est ensuite retourné et placé sur un cambre de faible courbure, et la surface est pressée (par exemple à la bouterolle). La pierre se fissure sur les rainures.According to a preferred embodiment, the stone is first refined into strips, then a grid of grooves or grooves is lasered on the back of the strip. The back of the coverslip is then fixed (for example glued) on a flexible support. For example, a metallic or other support with different suitable adhesion means. The assembly (glued lamella) is then turned over and placed on a camber of slight curvature, and the surface is pressed (for example with a chuck). The stone cracks on the grooves.

La taille et la forme de la pierre souple peuvent être ajustées par la suite de quelconques manières pour l'incorporation d'un article décoratif tel qu'un article de bijouterie, horlogerie (par exemple, un bracelet de montre), mode, maroquinerie, etc.The size and shape of the flexible stone can subsequently be adjusted in any way for the incorporation of a decorative article such as a jewelery item, watchmaking (for example, a watch strap), fashion, leather goods, etc.

Exemple(s) de mode de réalisation de l'inventionExample (s) of embodiment of the invention

Les figures 1 et 3 illustrent un procédé pour l'obtention d'une pierre flexible, selon un mode de réalisation. Le procédé comporte une étape de fournir une pierre sous la forme d'une plaque, lame ou lamelle ayant une première face 11 et une seconde face 12 opposée à la première face 11, les deux faces11, 12 étant préférablement sensiblement parallèles (figure 1a).The figures 1 and 3 illustrate a method for obtaining a flexible stone, according to one embodiment. The method includes a step of providing a stone in the form of a plate, blade or lamella having a first face 11 and a second face 12 opposite the first face 11, the two faces 11, 12 preferably being substantially parallel ( figure 1a ).

Par "pierre", on entend surtout, mais pas exclusivement, les pierres fines (pierres semi précieuses) par exemple telles que définies dans la liste de la "Confédération Internationale de Bijouterie, Joaillerie, Orfèvrerie des diamants, perles et pierres", comprenant l'agate, le jaspe, le lapis lazuli, l'onyx, l'améthyste, le jade, le cristal de roche, la malachite, l'opale des pierres organiques (ambre, nacre, ...) ou des pierres artificielles. Cette liste n'est pas exhaustive, et d'autres types de pierres utilisables pour la décoration d'un article peuvent aussi être utilisés.By "stone" is meant above all, but not exclusively, fine stones (semi-precious stones) for example as defined in the list of the "International Confederation of Jewelery, Jewelery, Goldsmithing of Diamonds, Pearls and Stones", including the agate, jasper, lapis lazuli, onyx, amethyst, jade, rock crystal, malachite, opal organic stones (amber, mother-of-pearl, ...) or artificial stones. This list is not exhaustive, and other types of stones usable for the decoration of an article can also be used.

La lamelle 1 peut être mise en forme à l'aide de toute méthode appropriée telle que par sciage ou taillage. Le sciage peut être réalisé à l'aide s'une scie au diamant ou la découpe par jet d'eau. Une étape de polissage est également possible. La lamelle 1 peut donc se présenter selon une forme et une épaisseur prédéfinies.The strip 1 can be shaped using any suitable method such as by sawing or cutting. Sawing can be done using a diamond saw or water jet cutting. A polishing step is also possible. The strip 1 can therefore have a predefined shape and thickness.

Le procédé comporte ensuite une étape de former une pluralité de rainures 2 dans la lamelle 1 sur la première face 11 (figure 1b).The method then comprises a step of forming a plurality of grooves 2 in the lamella 1 on the first face 11 ( figure 1b ).

Les rainures 2 peuvent être formées à l'aide d'un dispositif de gravure comprenant, par exemple un dispositif mécanique, tel qu'un dispositif de fraisage, ou encore un dispositif de découpe par jet d'eau.The grooves 2 can be formed using an etching device comprising, for example a mechanical device, such as a milling device, or even a water jet cutting device.

De manière préférée, le dispositif de gravure comprend un dispositif laser. Le dispositif laser peut comprendre un laser au dioxyde de carbone (laser au CO2), un laser Nd:YAG ou d'autres types de dispositif laser appropriés.Preferably, the engraving device comprises a laser device. The laser device can include a carbon dioxide laser (CO 2 laser), an Nd: YAG laser or other suitable types of laser device.

Les rainures 2 peuvent être formées selon un motif arbitraire, mais elles sont préférablement formées selon un motif contrôlé, tel qu'un quadrillage, un ensemble de lignes, un motif hexagonal, ou un motif triangulaire. La figure 2 montre la surface d'une lamelle 1 (ici une pierre de malachite) sur laquelle ont été gravé des rainures 2 selon un motif quadrillé.The grooves 2 can be formed in an arbitrary pattern, but they are preferably formed in a controlled pattern, such as a grid, a set of lines, a hexagonal pattern, or a triangular pattern. The figure 2 shows the surface of a strip 1 (here a malachite stone) on which grooves 2 have been engraved in a grid pattern.

Un guide destiné à guider la gravure peut être utilisé pendant l'étape de formation des rainures 2. Alternativement, le motif à graver peut être programmé dans le dispositif de gravure.A guide intended to guide the etching can be used during the step of forming the grooves 2. Alternatively, the pattern to be etched can be programmed in the etching device.

La profondeur des rainures 2 est de préférence telle qu'au moins 15% de l'épaisseur de la lamelle 1 reste non gravée (non divisée).The depth of the grooves 2 is preferably such that at least 15% of the thickness of the strip 1 remains unetched (not divided).

Selon une forme d'exécution, la profondeur des rainures 2 est de 50% à 85% de l'épaisseur de la lamelle 1. De manière préférée, la profondeur des rainures 2 est de 60% à 80% de l'épaisseur de la lamelle 1.According to one embodiment, the depth of the grooves 2 is from 50% to 85% of the thickness of the strip 1. Preferably, the depth of the grooves 2 is from 60% to 80% of the thickness of the coverslip 1.

Selon une forme d'exécution, l'épaisseur de la lamelle 1 est comprise entre 0,1 à 0,6 mm.According to one embodiment, the thickness of the strip 1 is between 0.1 to 0.6 mm.

A la suite de l'étape de formation des rainures 2, la première surface 11 peut être polie.Following the step of forming grooves 2, the first surface 11 can be polished.

Le procédé comporte ensuite une étape de fixer un support flexible 3 à la première face 11 de la lamelle 1, c'est-à-dire sur la surface comprenant les rainures 2, de manière à obtenir une lamelle composite 4 (figure 1c).The method then comprises a step of fixing a flexible support 3 to the first face 11 of the strip 1, that is to say on the surface comprising the grooves 2, so as to obtain a composite strip 4 ( figure 1c ).

Le support souple 3 peut être fabriqué dans tout matériau flexible, tel qu'un tissu, une pièce de cuir, un support métallique ou autre. Le support souple 3 peut être fixé sur la première surface 11 avec différents moyens appropriés, par exemple un adhésif.The flexible support 3 can be made of any flexible material, such as a fabric, a piece of leather, a metallic support or the like. The flexible support 3 can be fixed on the first surface 11 with various appropriate means, for example an adhesive.

Dans une étape ultérieure du procédé montrée à la figure 3, la lamelle composite 4 est disposée, du côté du support flexible 3, sur une surface cambrée 6 d'une pièce d'appui 5. Une pression 7 est alors appliquée sur la seconde face 12. La pression 7 peut être appliquée à l'aide d'une bouterolle, d'un rouleau ou d'autres moyens similaires. La pression 7 appliquée génère des fissures 8 au fond des rainures 2. Sous l'effet de la pression 7 et des fissures 8, la lamelle composite 4 se déforme jusqu'à venir épouser la forme de la surface cambrée 6. La figure 3 montre la lamelle composite 4 déformée sur la surface cambrée 6 et les fissures 8 formées en fond de rainures 2.In a subsequent step of the process shown in figure 3 , the composite strip 4 is disposed, on the side of the flexible support 3, on a cambered surface 6 of a support piece 5. A pressure 7 is then applied to the second face 12. The pressure 7 can be applied to the using a dowel, roller or other similar means. The pressure 7 applied generates cracks 8 at the bottom of the grooves 2. Under the effect of the pressure 7 and the cracks 8, the composite strip 4 deforms until it matches the shape of the arched surface 6. The figure 3 shows the composite strip 4 deformed on the arched surface 6 and the cracks 8 formed at the bottom of grooves 2.

Pendant l'application de la pression 7, les fissures formées se propagent généralement des rainures 2 vers la seconde face 12. La lamelle 1 est ainsi traversée sur sensiblement toute son épaisseur par la succession des rainures 2 et des fissures 8. Autrement dit, les fissures 8 s'étendent du fond de la rainure 2 vers (et de préférence sensiblement jusqu'à) la seconde face 12. Les rainures 2 et les fissures 8 divisent donc la lamelle 1 en une pluralité de portions 1a, ce qui rend la lamelle 1 flexible.During the application of the pressure 7, the cracks formed generally propagate from the grooves 2 towards the second face 12. The strip 1 is thus traversed over substantially its entire thickness by the succession of the grooves 2 and the cracks 8. In other words, the cracks 8 extend from the bottom of the groove 2 towards (and preferably substantially up to) the second face 12. The grooves 2 and the cracks 8 therefore divide the strip 1 into a plurality of portions 1a, which makes the strip 1 flexible.

La flexibilité de la lamelle 1, et donc de la lamelle composite 4 (appelée par la suite lamelle composite flexibilisée 4), peut être ajustée en variant la densité des rainures 2, et donc des fissures 8 et/ou la forme de la surface cambrée 6. Selon le motif formé par les rainures 2, la lamelle 1 sera flexible dans une seule direction ou selon plusieurs directions. Par exemple, un motif de rainures 2 comportant des lignes dans une seule direction rendra la lamelle 1 flexible seulement selon une direction perpendiculaire à celle des rainures 2. Un motif de rainures 2 quadrillé rendra la lamelle 1 flexible dans deux directions parallèles au plan de la lamelle 1.The flexibility of the strip 1, and therefore of the composite strip 4 (hereinafter called flexibilized composite strip 4), can be adjusted by varying the density of the grooves 2, and therefore of the cracks 8 and / or the shape of the arched surface. 6. Depending on the pattern formed by the grooves 2, the strip 1 will be flexible in one direction or in several directions. For example, a pattern of grooves 2 having lines in one direction will make the lamella 1 flexible only in a direction perpendicular to that of the grooves 2. A pattern of grooves 2 squared will make the lamella 1 flexible in two directions parallel to the plane of the coverslip 1.

Selon un mode de réalisation, la lamelle composite flexibilisée 4 est utilisée dans un article décoratif, par exemple, un article de bijouterie ou d'horlogerie, un bracelet, un article de mode, ou un article de maroquinerie.According to one embodiment, the flexibilized composite strip 4 is used in a decorative article, for example, a piece of jewelry or timepieces, a bracelet, a fashion item, or a leather goods item.

A cette fin, le procédé peut comprendre une étape d'ajuster la taille et la forme de la lamelle composite flexibilisée 4.To this end, the method may include a step of adjusting the size and the shape of the flexibilized composite strip 4.

La figure 4 montre une vue partielle d'un bracelet 20, selon une forme d'exécution. Le bracelet 20 comprend une bande 21 sur laquelle sont fixées une pluralité d'éléments décoratifs 22 comprenant chacun une lamelle composite flexibilisée 4. La figure 4a montre une vue de côté du bracelet et la figure 4b une vue de dessus. Dans la figure 4b, la bande 21 est représentée sertie de pierres 23 (pierres précieuses) mais toute autre configuration de la bande peut être envisagée.The figure 4 shows a partial view of a bracelet 20, according to an embodiment. The bracelet 20 comprises a band 21 on which are fixed a plurality of decorative elements 22 each comprising a flexible composite lamella 4. The figure 4a shows a side view of the bracelet and the figure 4b a top view. In the figure 4b , the band 21 is shown set with stones 23 (precious stones) but any other configuration of the band can be envisaged.

Selon une forme d'exécution (non visible dans la figure 4), chacun des éléments décoratifs 22 comporte deux lamelles composites flexibilisées 4 assemblées l'une à l'autre du côté du support 3, de manière à ce que la seconde face 12 montrant la pierre soit visible des deux côtés des éléments décoratifs 22. Les deux lamelles composites flexibilisées 4 peuvent être collées parallèle l'une à l'autre.According to an embodiment (not visible in the figure 4 ), each of the decorative elements 22 comprises two flexible composite strips 4 assembled to one another on the side of the support 3, so that the second face 12 showing the stone is visible on both sides of the decorative elements 22. The two composite flexible strips 4 can be bonded parallel to each other.

Dans l'exemple particulier des figures 4a et 4b, les lamelles composites flexibilisées 4 sont découpées de sorte à donner à l'élément décoratif 22 une forme de feuille ovale. La figure 4b montre la pluralité d'éléments décoratifs 22 répartis de chaque côté de la bande 21. Les éléments décoratifs 22 comprenant les lamelles composites flexibilisées 4 sont souples et aptes à fléchir au toucher, conférant au bracelet un aspect ondoyant et des caractéristiques tactiles particulières.In the particular example of Figures 4a and 4b , the flexible composite strips 4 are cut so as to give the decorative element 22 an oval sheet shape. The figure 4b shows the plurality of decorative elements 22 distributed on each side of the strip 21. The decorative elements 22 comprising the flexibilized composite lamellae 4 are flexible and capable of bending to the touch, giving the bracelet an undulating appearance and particular tactile characteristics.
