Description

La présente invention est relative au domaine de la joaillerie, plus particulièrement à un article de joaillerie comprenant un système de fixation invisible permettant l'assemblage de plusieurs pierres précieuses (voir US-A-2002166337).The present invention relates to the field of jewelery, more particularly to a jewelery article comprising an invisible fastening system allowing the assembly of several precious stones (see US-A-2002166337).

Ce système de fixation invisible permet de créer, grâce à un agencement spécial de plusieurs pierres précieuses, un aspect esthétique qui donne l'illusion de n'apercevoir qu'une seule pierre précieuse de grande dimension lorsque celle-ci est observée côté table.This invisible fastening system makes it possible to create, thanks to a special arrangement of several precious stones, an aesthetic aspect which gives the illusion of seeing only one large gemstone when it is observed on the table side.

Le sertissage invisible est bien connu et répandu dans le domaine de la joaillerie. Plusieurs procédés de sertissage invisible de pierres précieuses font déjà partie de l'état de la technique.Invisible crimping is well known and widespread in the field of jewelery. Several methods of invisible gemstone crimping are already part of the state of the art.

Pour faciliter la compréhension de cet exposé, la figure 7 représente une pierre précieuse avec les indications des termes usuels qui sont entre autre utilisés dans la suite de cet exposé.To facilitate the understanding of this presentation, Figure 7 represents a gemstone with the indications of the usual terms that are used among others in the rest of this presentation.

Le document N° US 6,112,552 propose un système de fixation invisible composé de plusieurs rainures parallèles les unes par rapport aux autres destinées à recevoir des pierres précieuses de forme rectangulaire agencées les unes à côté des autres. La largeur des rainures a été déterminée de manière à rendre invisible le moyen de fixation lorsque toutes les pierres sont assemblées. Les flans des rainures possèdent un épaulement et une certaine élasticité afin de permettre d'une part l'assemblage desdites pierres par simple pression exercée sur ces dernières et d'autre part le maintien de ces pierres dans leurs emplacements grâce à la pression exercée par l'épaulement dans des gorges longitudinales taillées dans la culasse de la pierre précieuse. Ce dispositif est usuellement appelé le serti à rail.Document US Pat. No. 6,112,552 proposes an invisible fastening system composed of several mutually parallel grooves intended to receive rectangular shaped gems arranged next to one another. The width of the grooves has been determined so as to make the fixing means invisible when all the stones are assembled. The flanks of the grooves have a shoulder and a certain elasticity so as to allow on the one hand the assembly of said stones by simple pressure exerted on them and on the other hand the maintenance of these stones in their locations thanks to the pressure exerted by the shoulder in longitudinal grooves cut into the cylinder head of the gemstone. This device is usually called the rail crimp.

Un autre dispositif décrit dans le document N° FR 2627359 propose un sertissage invisible présentant l'avantage d'une part de ne chever (le chevage est un terme technique décrivant les gorges longitudinales à tailler dans la culasse) qu'une pierre sur deux et d'autre part de réduire l'apparition des gorges côté table de la pierre précieuse. Les pierres chevées maintiennent les pierres non chevées dans leur logement. Ce dispositif permet non pas de supprimer les gorges côté table des pierres mais uniquement de les atténuer.Another device described in the document No. FR 2627359 proposes an invisible crimping having the advantage of not chever (the anchoring is a technical term describing the longitudinal grooves to carve in the breech) that one stone out of two and on the other hand to reduce the appearance of throats side table of the gemstone. Stones hold the unpaved stones in their dwelling. This device does not remove the grooves table side stones but only to mitigate them.

Le document US 5,649,434 propose quant à lui un sertissage invisible pour un seul et unique diamant de forme « taille brillant ». Ce diamant comporte deux surfaces planes situées sur la culasse du diamant à 180° l'une de l'autre juste au-dessous du rondiste. Chacune de ces deux surfaces comporte une gorge longitudinale dans laquelle est chassé un épaulement situé sur le diamètre interne côté bord d'un cylindre servant de support. Le diamètre externe de ce cylindre correspond au diamètre du rondiste de manière à pouvoir être partiellement dissimulé lorsque le diamant est observé.Document US Pat. No. 5,649,434 proposes for its part an invisible setting for a single diamond of shape "brilliant cut". This diamond has two flat surfaces located on the diamond head at 180 ° to each other just below the girdle. Each of these two surfaces has a longitudinal groove in which is driven a shoulder located on the inner diameter edge of a cylinder serving as a support. The outer diameter of this cylinder corresponds to the diameter of the rounder so that it can be partially concealed when the diamond is observed.

Tous les dispositifs décrits dans l'état de la technique permettent uniquement d'agencer des pierres précieuses parallèlement les unes par rapport aux autres limitant ainsi la forme géométrique obtenue à un rectangle ou un carré. D'autre part ces dispositifs bien que masquant le support ne supprime pas l'apparition des gorges côté table des pierres précieuses lorsque ces dernières sont assemblées les unes aux autres. Les sertissages invisibles destinés à une forme géométrique ronde tel que le document US 5,649,434 ne comporte qu'une seule et unique pierre.All the devices described in the state of the art can only arrange gems parallel to each other with respect to others thus limiting the geometric shape obtained to a rectangle or a square. On the other hand, these devices, while masking the support, do not eliminate the appearance of the table-side gemstones gemstones when they are assembled to each other. Invisible crimps for a round geometric shape such as US 5,649,434 includes only one stone.

Le but de la présente invention est de proposer un système de sertissage invisible ou mystérieux qui à la particularité de pouvoir assembler autour d'une pierre précieuse central plusieurs pierres précieuses de forme prédéfinies de sorte à supprimer entièrement les gorges côté table des pierres précieuses. Cela permet de créer un aspect esthétique qui donne l'illusion de n'apercevoir qu'une seule et unique pierre précieuse de grande dimension lorsque celle-ci est observée côté table.The object of the present invention is to provide an invisible or mysterious crimping system which has the particularity of being able to assemble around a central gemstone several precious stones of predefined shape so as to completely remove the gorges table side gemstones. This creates an aesthetic appearance that gives the illusion of seeing only one single large gemstone when it is observed table side.

Conformément à l'invention, ce but est atteint grâce à un article de joaillerie et un article décoratif selon les revendications 1 et 6 constitué d'une pierre centrale et de plusieurs pierres périphériques agencées autour de ladite pierre centrale sur un support spécial. Celui-ci comporte un premier anneau concentrique et solidaire d'un deuxième anneau de diamètre inférieur et de hauteur supérieur au premier anneau. Lesdits anneaux sont solidaires par exemple grâce à plusieurs branches concourantes agencées entre la base du premier et du deuxième anneau à intervalle régulier. Le deuxième anneau possède un épaulement en forme de T sur son bord supérieur dont l'un de ses côtés est destiné à être chassé dans une gorge longitudinale se trouvant sur l'intégralité de la circonférence de la culasse de la pierre centrale et l'autre de ses côtés est chassé dans une gorge se trouvant sur l'une des facettes des pierres périphériques. Ces dernières sont également maintenues fermement dans leurs positions grâce à une rainure réalisée sur le périmètre interne du deuxième anneau.According to the invention, this object is achieved through a jewelery article and a decorative article according to claims 1 and 6 consisting of a central stone and several peripheral stones arranged around said central stone on a special support. This comprises a first concentric ring and secured to a second ring of smaller diameter and height greater than the first ring. Said rings are secured for example by several concurrent branches arranged between the base of the first and the second ring at regular intervals. The second ring has a T-shaped shoulder on its upper edge one of whose sides is intended to be driven into a longitudinal groove lying on the entire circumference of the breech of the central stone and the other from its sides is chased in a gorge lying on one of the facets of the peripheral stones. The latter are also held firmly in their positions thanks to a groove made on the inner perimeter of the second ring.

Cet article de joaillerie a l'avantage de présenter un feu continu entre la pierre centrale (2) et les pierres périphériques (3) grâce à l'absence de gorges usuellement provoquées par les systèmes décrits dans l'état de la technique.This jewelery article has the advantage of having a continuous fire between the central stone (2) and the peripheral stones (3) due to the absence of grooves usually caused by the systems described in the state of the art.

Ainsi, cet article de joaillerie présente le même aspect esthétique que les pierres précieuses ordinaires de différentes tailles tel que cinq, dix ou quinze carats tout en ayant un prix de revient beaucoup moins important puisque la matière brute est réduite sensiblement.Thus, this jewelry article has the same aesthetic appearance as ordinary gems of different sizes such as five, ten or fifteen carats while having a much lower cost since the raw material is reduced significantly.

D'autres caractéristiques de l'invention sont exposées dans les revendications et ressortiront dans la description qui suit.Other features of the invention are set forth in the claims and will become apparent in the description which follows.

Selon ce mode d'exécution de la présente invention, un article de joaillerie (1) est constitué d'un diamant octogonal (2) et de huit petits diamants trapézoïdales (3). Ces diamants sont maintenus solidaires les uns des autres grâce à un support spécial (4).According to this embodiment of the present invention, a jewelery item (1) consists of an octagonal diamond (2) and eight small trapezoidal diamonds (3). These diamonds are held together by a special support (4).

Ledit support (4) est constitué d'un premier anneau (5) concentrique à un deuxième anneau (6) de diamètre inférieur et de hauteur supérieur au premier anneau (5). Les deux anneaux (5, 6) sont solidarisés à leur base par plusieurs branches (7) concourantes agencées à intervalle régulier. Le deuxième anneau (6) possède un épaulement (8) en forme de T sur son bord supérieur. L'un des côtés de l'épaulement (8) est destiné à être chassé dans une gorge longitudinale (9) se trouvant sur l'intégralité de la circonférence de la culasse (10) du diamant octogonal (2). L'autre côté de l'épaulement (8) est chassé dans une gorge (11) se trouvant sur l'une des facettes proche du bord de chaque petit diamant (3). Celui-ci est également maintenu fermement dans sa position grâce à une rainure (12) réalisée sur le périmètre interne du premier anneau (5). L'agencement de chaque petit diamant (3) les uns à côté des autres sur le pourtour de la pierre centrale (2) grâce au support (4) permet de reproduire de manière continue la couronne d'un diamant taille brillant.Said support (4) consists of a first ring (5) concentric with a second ring (6) of smaller diameter and greater height than the first ring (5). The two rings (5, 6) are secured at their base by several branches (7) concurrent arranged at regular intervals. The second ring (6) has a T-shaped shoulder (8) on its upper edge. One of the sides of the shoulder (8) is intended to be driven into a longitudinal groove (9) lying on the entire circumference of the cylinder head (10) of the octagonal diamond (2). The other side of the shoulder (8) is driven into a groove (11) on one of the facets close to the edge of each small diamond (3). It is also held firmly in its position thanks to a groove (12) made on the inner perimeter of the first ring (5). The arrangement of each small diamond (3) next to each other around the central stone (2) through the support (4) can reproduce continuously the crown of a diamond brilliant cut.

Lesdits huit petits diamants (3) ont été taillés de sorte à ce que la longueur du bord de l'un de leurs côtés est identique à la longueur du bord de l'une des facettes (14) situées sur la couronne du diamant octogonal (2).Said eight small diamonds (3) have been cut so that the length of the edge of one of their sides is identical to the length of the edge of one of the facets (14) located on the crown of the octagonal diamond ( 2).

La hauteur et le diamètre du premier anneau (5) ont été déterminés de sorte à créer un angle d'incidence de la table (13) des huit petits diamants (3) correspondant à l'angle d'incidence de l'une des facettes (14) de la couronne du diamant octogonal (2).The height and the diameter of the first ring (5) have been determined so as to create an angle of incidence of the table (13) of the eight small diamonds (3) corresponding to the angle of incidence of one of the facets (14) the crown of the octagonal diamond (2).

L'agencement de ladite facette de la couronne du diamant octogonal (2) est réalisé de manière adjacente à l'un des bords de la table (13) du petit diamant (3) de manière à reconstituer le bezel (15) d'un diamant « taille brillant ». L'agencement des deux facettes reconstituant ledit bezel (15) sur le même plan assure un feu continu.The arrangement of said facet of the crown of the octagonal diamond (2) is made adjacent to one of the edges of the table (13) of the small diamond (3) so as to reconstitute the bezel (15) of a diamond "brilliant cut". The arrangement of the two facets restoring said bezel (15) on the same plane ensures a continuous fire.

Ainsi, ce système de sertissage permet de transformer un authentique petit diamant « taille 16/16» en un diamant plus grand « taille brillant » lorsque celui-ci est observé de dessus tout en utilisant environ un dixième de la matière brut nécessaire à la réalisation d'un diamant authentique de ce type.Thus, this crimping system makes it possible to transform an authentic small "size 16/16" diamond into a larger "brilliant cut" diamond when it is observed from above while using approximately one-tenth of the raw material necessary for the realization of an authentic diamond of this type.

Dans cette exécution, le pourtour du cylindre (5) est continu et opaque masquant ainsi le dispositif de fixation tandis que le cylindre (6) peut présenter des discontinuités.In this embodiment, the periphery of the cylinder (5) is continuous and opaque thus masking the fixing device while the cylinder (6) may have discontinuities.

Le mode de réalisation n'est nullement limitatif et par conséquent au lieu de la forme d'exécution décrite ci-dessus, les diamants peuvent être remplacés par n'importe quel autre type de pierres précieuses ou semi-précieuses afin de pouvoir proposer des articles de joaillerie présentant divers aspects esthétiques.The embodiment is in no way limiting and therefore instead of the embodiment described above, the diamonds can be replaced by any other type of precious or semi-precious stones in order to be able to offer articles. jewelery with various aesthetic aspects.

L'article de joaillerie (1) peut être monté sur une bague où un pendentif.The item of jewelry (1) can be mounted on a ring where a pendant.

L'invention n'est pas limitée aux bagues, mais est applicable à toutes sortes d'articles de joailleries tels que les boucles d'oreilles, les colliers, les bracelets.The invention is not limited to rings, but is applicable to all kinds of jewelry items such as earrings, necklaces, bracelets.

L'invention concerne aussi un article décoratif comportant l'article de joaillerie de la présente invention.The invention also relates to a decorative article comprising the article of jewelry of the present invention.
