Abstract
Description
o
La présente invention concerne un dispositif de fixation invisible du diamant. etdes pierres précieuses en général sur une monture rigide ou en montage souple.o
The present invention relates to an invisible diamond fixing device. and precious stones in general on a rigid frame or in flexible mounting.
Traditionnellement, les diamants et les pierres précieuses sont fixées sur leur monture, par des griffes dans le cas de châtons, ou des sertissures de métal dans le cas du serti dit "clos", rabattus sur la pierre. La fixation est donc visible. Traditionally, diamonds and precious stones are fixed on their setting, by claws in the case of chatons, or metal crimps in the case of the so-called "closed" setting, folded over the stone. The binding is therefore visible.
Certains dispositifs permettent de fixer les pierres d'une façon invisible grâce à une ou deux entailles longitudinales dans le pavillon, sous le feuilletis. Certain devices make it possible to fix the stones in an invisible way thanks to one or two longitudinal notches in the pavilion, under the laminate.
Ces dispositifs sont couramment utilisés pour les pavages en saphir, rubis et émeraude. Quant au diamant, sa dureté d'une part, et sa transparence d'autre part semblent être des obsta.eles redhibitoires à l'utilisation de ces dispositifs. These devices are commonly used for sapphire, ruby and emerald paving. As for diamond, its hardness on the one hand, and its transparency on the other hand seem to be obstacles to the use of these devices.
Le dispositif selon l'invention permet de remédier à ces inconvénients,
La figure 1 représente, vu de dessous, le dispositif selon l'invention.The device according to the invention overcomes these drawbacks,
Figure 1 shows, seen from below, the device according to the invention.
I1 consiste à pratiquer dans la pierre, au moyen d'une scie ou d'un laser, une encoche (1) sur chaque arrête (2) du pavillon, sous le feuilletis (3). I1 consists in practicing in stone, by means of a saw or a laser, a notch (1) on each edge (2) of the pavilion, under the laminate (3).
La figure 2 représente, de profil, le dispositif selon l'invention. FIG. 2 shows, in profile, the device according to the invention.
Une pierre (4) est fixée par encliquetage ou sertie sur un châton (5) lui-même destiné à être, soit fixé sur la monture (27) du bijou, soit à constituer un élément d'un montage souple grâce à un emmaillement (6) qui le relie à un autre chaton. A stone (4) is fixed by snap-fastening or crimped on a kitten (5) itself intended to be, either fixed on the setting (27) of the jewel, or to constitute an element of a flexible assembly thanks to an enameling ( 6) which connects him to another kitten.
Les figures 3 et 4 reprennent, en coupe, le dispositif selon l'invention. Figures 3 and 4 show, in section, the device according to the invention.
Elles représentent, en coupe, une pierre (4) enserrée par la griffe (7) d'un châton. They represent, in section, a stone (4) enclosed by the claw (7) of a kitten.
La profondeur (8) de l'encoche (1) ne doit pas excéder l'aplomb (9) de la limite intérieure (10) du bezel (11). The depth (8) of the notch (1) must not exceed the plumb (9) of the inner limit (10) of the bezel (11).
La fixation de la pierre sur le châton consiste à faire pénétrer la saillie (12) de la griffe (7) à l'intérieur de l'encoche (1) de la pierre. The fixing of the stone on the kitten consists in making the projection (12) of the claw (7) penetrate inside the notch (1) of the stone.
Cette fixation peut être effectuée par serti ou encliquetage. Dans ce dernier cas, l'arrête (2) du pavillon du diamant, en contact avec le chanfrein (13) de la saillie (12), écarte cette dernière (14) quand on effectue une pression de haut en bas (15) pour encliqueter la pierre. La saillie (12) se rabat (16) alors dans l'encoche maintenant ainsi la pierre fixée.This fixing can be done by crimping or snap-fastening. In the latter case, the stop (2) of the pavilion of the diamond, in contact with the chamfer (13) of the projection (12), spreads the latter (14) when pressure is applied from top to bottom (15) to snap the stone. The projection (12) folds down (16) then in the notch thus maintaining the fixed stone.
La figure 2 représente, grossie et en coupe, une pierre (4) sertie ou encliquetée d'une façon définitive. Le plan de contact (17) entre les parties inférieures de la saillie et de l'encoche, forme un angle de 900 (18) environ, par rapport à l'axe vertical de la pierre, empêchant ainsi un mouvement de bas en haut-(19) de la pierre, par rapport au châton. Figure 2 shows, enlarged and in section, a stone (4) crimped or snapped permanently. The contact plane (17) between the lower parts of the projection and the notch forms an angle of approximately 900 (18), relative to the vertical axis of the stone, thus preventing movement from bottom to top. (19) stone, compared to the kitten.
La figure 4 représente, en coupe, au contraire, une pierre encliquetée ou sertie dont le plan de contact (20), entre les parties inférieures de la saillie et de l'encoche forme un angle de 450 maximum (21) par rapport à l'axe vertical de la pierre. FIG. 4 represents, in section, on the contrary, a latched or crimped stone whose contact plane (20), between the lower parts of the projection and the notch forms an angle of maximum 450 (21) relative to the vertical axis of the stone.
La figure 5 représente, vu de dessus , le dispositif selon l'invention. FIG. 5 represents, seen from above, the device according to the invention.
Le châton (29) présente des griffes (30) à section en "L" comportant à leur extrêmité une saillie (31) triangulaire de métal qui se loge dans I'encoche par encliquetage ou serti. The kitten (29) has claws (30) with an "L" section comprising at their end a triangular projection (31) of metal which is housed in the notch by snap-fastening or crimped.
La figure 6 représente, de profil, une alternative du dispositif selon l'invention. FIG. 6 represents, in profile, an alternative of the device according to the invention.
Il s'agit d'un châton (23) à deux griffes (24). Ces dernières possèdent à leur extrêmité une double saillie de section triangulaire (25) qui se loge dans les deux encoches (1) des pierres (4) juxtaposées, par serti ou encliquetage. It is a kitten (23) with two claws (24). The latter have at their end a double projection of triangular section (25) which is housed in the two notches (1) of the stones (4) juxtaposed, by crimping or snap-fastening.
La figure 7 représente, de profil, une alternative du dispositif selon l'invention sous la forme d'un plot (26) solidaire de la monture (27) dont la tête (28), en forme de clou, présente des saillies (32) qui se logent par serti ou encliquetage dans les encoches (l) des pierres juxtaposées. FIG. 7 represents, in profile, an alternative of the device according to the invention in the form of a stud (26) integral with the mount (27) whose head (28), in the shape of a nail, has projections (32 ) which are housed by crimping or snap-fastening in the notches (l) of the juxtaposed stones.
Ce-dispositif, selon l'invention, peut être réalisé en or de toute couleur, de tout titre, ou én tout autre métal dont l'emploi serait justifié par ses caractéristiques de résistance et d'élasticité. This device, according to the invention, can be made of gold of any color, any title, or any other metal whose use would be justified by its characteristics of resistance and elasticity.
Ce dispositif, selon l'invention, est particulièrement destiné à la réalisation de pavages de pierres juxtaposées sans monture ou fixation apparente. This device, according to the invention, is particularly intended for producing pavings of juxtaposed stones without frame or visible fixing.
