DISPOSITIF DE FIXATION POUR CHATON AMOVIBLE DE BIJOU, CHATON ET PIÈCE DE BIJOUTERIE ADAPTÉS À LA MISE EN FIXING DEVICE FOR REMOVABLE JEWELRY CAT, KITTEN AND JEWELRY PIECE SUITABLE FOR USE
OEUVRE DE CE DISPOSITIFWORK OF THIS DEVICE
ARRIÈRE PLAN TECHNOLOGIQUE DE L'INVENTIONTECHNOLOGICAL BACKGROUND OF THE INVENTION
L'invention concerne un dispositif de fixation pour chaton amovible de bijou et une pièce de bijouterie, notamment de type bague, bracelet, broche, collier, pendentif ou boucle d'oreille, adaptée à la mise en oeuvre d'un tel dispositif.The invention relates to a fixing device for a removable jewel kitten and a piece of jewelry, in particular of the ring, bracelet, brooch, necklace, pendant or earring type, suitable for the implementation of such a device.
Elle a aussi pour objet un chaton également adapté à la mise en oeuvre dudit dispositif.It also relates to a kitten also suitable for the implementation of said device.
Les bijoux à chatons amovibles, le plus souvent les bagues, sont bien connus de l'état de l'art antérieur : pour une même monture, le porteur peut ainsi, à son gré, selon son humeur et les circonstances, choisir dans toute une gamme de pierres fines ou précieuses enchâssées chacune dans un chaton, ces ensembles "chaton/pierre" étant bien sûr appropriés à la monture en cause et étant acquis par le porteur en même temps que ladite monture, ou séparément. Ainsi, tout en ne disposant que d'une seule monture, son porteur peut modifier à volonté l'aspect de son bijou puisque, en associant à ladite monture l'ensemble "chaton/pierre" de son choix, il peut construire un bijou dont la pierre est à la fois de la forme qu'il désire, ronde, ovale, rectangle, carrée par exemple, de la couleur et de la nature qu'il désire.Jewelry with removable kittens, most often rings, are well known from the state of the prior art: for the same frame, the wearer can thus, at will, according to his mood and the circumstances, choose from a whole range of fine or precious stones each embedded in a kitten, these "kitten / stone" sets being of course suitable for the frame in question and being acquired by the wearer at the same time as said frame, or separately. Thus, while having only one frame, its wearer can modify the appearance of his jewel at will since, by associating with said frame the "kitten / stone" set of his choice, he can build a jewel of which the stone is both the shape he wants, round, oval, rectangle, square for example, the color and the nature he wants.
De la demande de brevet FR-A-2.595.925, on connaît par exemple un type de chaton amovible retenu sur le corps du bijou par des moyens déformables, présentant des fenêtres, conjugués à des moyens à crochets qui pénètrent lesdites fenêtres. Le dispositif de fixation du chaton ainsi envisagé présente toutefois deux inconvénients : il est particulièrement volumineux, et de ce fait il n'est adaptable que sur des bijoux de grande dimension, et il n'offre aucune sécurité quant au maintien du chaton sur le bijou, les moyens à crochets qui pénètrent les fenêtres n'étant retenus dans celles-ci que par simple frottement, donc sans verrouillage véritable. De la demande de brevet FR-A-2.662.058, on connaît également un autre type de chaton amovible : dans ce cas, un anneau élastique (clip) maintient dans son logement le support de la pierre du bijou.From patent application FR-A-2,595,925, there is known for example a type of removable kitten retained on the body of the jewel by deformable means, having windows, combined with hook means which penetrate said windows. The kitten fixing device thus envisaged has however two drawbacks: it is particularly bulky, and therefore it is only adaptable on large jewelry, and it offers no security as to the maintenance of the kitten on the jewel , the hook means which penetrate the windows being retained in them only by simple friction, therefore without real locking. From patent application FR-A-2,662,058, another type of removable kitten is also known: in this case, an elastic ring (clip) keeps the support for the jewel stone in its housing.
La fabrication de ces types de chatons amovibles présente l'inconvénient supplémentaire de nécessiter des moulages et des usinages complexes.The manufacture of these types of removable kittens has the additional disadvantage of requiring complex moldings and machining.
Selon une technique plus ancienne, simple et fiable, la pierre elle-même était interchangeable sans outil.According to an older, simple and reliable technique, the stone itself was interchangeable without tools.
Le brevet FR-A-1.552.092 dévoile un système de griffes articulées sur le corps de la bague qui enserrent la pierre dans son panierPatent FR-A-1,552,092 discloses a system of claws articulated on the body of the ring which enclose the stone in its basket
L'inconvénient de ces sortes de fixation est qu'elles ne s'adaptent pas aux pierres de n'importe quelle taille et de n'importe quelle forme.The disadvantage of these kinds of fastening is that they do not fit stones of any size and shape.
Enfin, il est connu de FR-A-2.598.602, de EP-A- 0 313 710 et de FR-A-1.535.640, de fixer un chaton, par essence amovible, à un bijou, au moyen d'une tige filetée fixée soit sur le corps du bijou, soit à la base du chaton, et d'un trou taraudé complémentaire de la tige filetée, percé soit dans la base du chaton, soit dans le corps du bijou.Finally, it is known from FR-A-2,598,602, from EP-A-0 313 710 and from FR-A-1.535.640, to fix a kitten, essentially removable, to a jewel, by means of a threaded rod fixed either on the body of the jewel, or at the base of the kitten, and a tapped hole complementary to the threaded rod, drilled either in the base of the kitten, or in the body of the jewel.
De tels dispositifs ont toutefois pour inconvénient évident qu'ils peuvent trop facilement se désolidariser, le chaton se dévissant progressivement, ne serait-ce que du fait du frottement du bijou, par exemple sur un vêtement, auquel cas le porteur du bijou risque tôt ou tard de perdre le chaton.However, such devices have the obvious drawback that they can too easily become detached, the kitten gradually unscrewing, if only because of the friction of the jewel, for example on a garment, in which case the wearer of the jewel risks early or late to lose the kitten.
DESCRIPTION GÉNÉRALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION
La présente invention vise donc à pallier les inconvénients des dispositifs de fixation de chatons amovibles connus.The present invention therefore aims to overcome the drawbacks of known removable kittens fixing devices.
A cet effet, elle a plus précisément pour objet un dispositif de fixation pour chaton amovible de bijou, du type comprenant des moyens coopérants d'assemblage et de désassemblage mécanique dudit chaton et du corps dudit bijou, constitués de façon connue par exemple de EP-A-0 313 710 d'une tige filetée fixée sur le corps du bijou et d'un trou taraudé percé dans la base du chaton, caractérisé en ce qu'il comporte au moins deux palmettes articulées chacune à leur première extrémité sur le corps du bijou et munies chacune à leur seconde extrémité de moyens d'accrochage et de décrochage du chaton.To this end, it more specifically relates to a fixing device for a removable jewel kitten, of the type comprising cooperating means for assembly and mechanical disassembly of said kitten and of the body of said jewel, constituted in a known manner for example of EP- A-0 313 710 with a threaded rod fixed on the body of the jewel and a threaded hole drilled in the base of the kitten, characterized in that it comprises at least two palmettes articulated each at their first end on the body of the jewel and each provided at their second end with means for attaching and detaching the kitten.
Le chaton étant ainsi bloqué en rotation sur le corps du bijou, il n'y a plus aucun risque qu'il se dévisse progressivement jusqu'à se désolidariser du corps du bijou sans que le porteur du bijou s'en aperçoive. Avantageusement, ces moyens d'accrochage et de décrochage du chaton peuvent être constitués par un ergot pouvant être inséré ou extrait d'un anneau fixé audit chaton, par exemple sur sa paroi latérale.The kitten being thus blocked in rotation on the body of the jewel, there is no longer any risk that it will unscrew gradually until it becomes detached from the body of the jewel without the wearer of the jewel noticing. Advantageously, these means for attaching and detaching the kitten may consist of a lug which can be inserted or removed from a ring fixed to said kitten, for example on its side wall.
De préférence, la seconde extrémité de chaque palmette comporte une épingle sertie constituant l'ergot.Preferably, the second end of each palmette has a crimped pin constituting the lug.
L'ergot peut aussi être une pointe dont la forme en S garantit son blocage automatique après qu'il a été inserré par déformation élastique dans l'anneau du chaton.The lug can also be a point whose S-shape guarantees its automatic blocking after it has been inserted by elastic deformation in the kitten's ring.
Selon une variante de construction particulièrement avantageuse, le dispositif de fixation selon l'invention comprend en outre des moyens de centrage automatique des anneaux du chaton relativement aux palmettes en fin de vissage dudit chaton sur le corps du bijou. Ces moyens de centrage peuvent alors être constitués de butées placées sur le corps du bijou, au droit des palmettes, chaque anneau étant doté d'une échancrure complémentaire d'une butée, formée à la périphérie dudit anneau dans sa partie diamétralement opposée à la partie de fixation de l'anneau sur le chaton.According to a particularly advantageous variant of construction, the fixing device according to the invention further comprises means for automatically centering the rings of the kitten relative to the palmettes at the end of screwing said kitten on the body of the jewel. These centering means can then consist of stops placed on the body of the jewel, in line with the palmettes, each ring having a notch complementary to a stop, formed at the periphery of said ring in its part diametrically opposite to the part fixing the ring on the kitten.
La première extrémité de chaque palmette peut par exemple être articulée sur le corps du bijou soit par un rivet présentant un léger jeu, soit par une charnière.The first end of each palmette can for example be articulated on the body of the jewel either by a rivet having a slight play, or by a hinge.
L'invention a pour deuxième objet un chaton de bijou caractérisé en ce que sa paroi latérale comporte au moins deux anneaux.The second object of the invention is a jewel kitten characterized in that its side wall has at least two rings.
Dans une variante avantageuse de réalisation, chaque anneau peut être doté d'une échancrure formée à sa périphérie dans sa partie diamétralement opposée à la partie de fixation de l'anneau sur le chaton.In an advantageous variant embodiment, each ring can be provided with a notch formed at its periphery in its part diametrically opposite to the part for fixing the ring to the kitten.
L'invention est avantageusement mise en oeuvre dans toute pièce de bijouterie de type bague, bracelet, broche, collier, pendentif ou boucle d'oreille adaptée. Il suffira alors que, de façon connue en soi, le corps de cette pièce comprenne par exemple une tige filetée, soudée audit corps soit directement, soit par l'intermédiaire d'une pièce rapportée, et qu'en outre, de part et d'autre de cette tige filetée, le corps de ladite pièce comporte au moins deux méplats au niveau des articulations avec les palmettes. Alternativement, le corps de la pièce de bijouterie comporte au moins deux fentes destinées à recevoir les extrémités des palmettes et au moins deux paliers pour le maintien des axes des charnières constituant chacune l'articulation d'une palmette sur le corps de la pièce de bijouterie.The invention is advantageously implemented in any piece of jewelry of the ring, bracelet, brooch, necklace, pendant or suitable earring type. It will then suffice that, in a manner known per se, the body of this part comprises, for example, a threaded rod, welded to said body either directly or by means of an attached part, and that, in addition, on both sides. 'Other of this threaded rod, the body of said part has at least two flats at the joints with the palmettes. Alternatively, the body of the piece of jewelry comprises at least two slots intended to receive the ends of the palmettes and at least two bearings for maintaining the axes of the hinges each constituting the articulation of a palmette on the body of the piece of jewelry .
Toujours dans une variante avantageuse de réalisation, ladite pièce de bijouterie peut comporter des butées placées sur le corps du bijou, et disposées chacune au droit de chaque palmette. On comprendra bien l'invention à la lecture du complément de description qui va suivre et en référence aux dessins annexés qui font partie de la description.Still in an advantageous alternative embodiment, said piece of jewelry may include stops placed on the body of the jewel, and each arranged in line with each palmette. The invention will be clearly understood on reading the additional description which follows and with reference to the appended drawings which form part of the description.

DESCRIPTION D'UNE FORME D'EXÉCUTION PRÉFÉRÉE DE L'INVENTIONDESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
Le bijou représenté sur les dessins est une bague. Il va toutefois de soi que cette bague n'est choisie qu'à simple titre illustratif et que l'invention s'applique à tout autre bijou comportant une pierre, par exemple un bracelet, un collier, une broche, un pendentif ou une boucle d'oreille.The jewel shown in the drawings is a ring. It goes without saying, however, that this ring is chosen for illustrative purposes only and that the invention applies to any other jewel comprising a stone, for example a bracelet, a necklace, a brooch, a pendant or a loop. ear.
Les références à la Figure 1 serviront à décrire les différentes caractéristiques de l'invention.The references to Figure 1 will be used to describe the various features of the invention.
Le corps de la bague est constitué d'un anneau (1) sur lequel, extérieurement, est fixée une tige (3) filetée.The body of the ring consists of a ring (1) on which, externally, is fixed a threaded rod (3).
Cette tige est soit soudée directement à l'anneau, soit soudée à une partie rapportée (2) elle-même soudée à l'anneau.This rod is either welded directly to the ring, or welded to an attached part (2) itself welded to the ring.
Le chaton amovible (4) a la forme d'un panier tronconique s'évasant vers le haut et dans lequel la pierre (5) est enchâssée et maintenue par des griffes (6) prévues au niveau de la grande base, ou sommet, du chaton. Le chaton (4) possède à sa petite base un renflement (7) percé d'une cavité cylindrique taraudée (7a), qui est complémentaire de cette tige (3), et dans laquelle la tige (3) s'engage par vissage. Le chaton (4) ne dispose plus ainsi que d'un seul degré de liberté, en rotation relativement au corps (1) de la bague.The removable kitten (4) has the shape of a frustoconical basket flaring upwards and in which the stone (5) is embedded and held by claws (6) provided at the level of the large base, or top, of the kitten. The kitten (4) has at its small base a bulge (7) pierced with a tapped cylindrical cavity (7a), which is complementary to this rod (3), and in which the rod (3) engages by screwing. The kitten (4) thus has only one degree of freedom, in rotation relative to the body (1) of the ring.
Les hauteurs relatives de la tige (3) et de la pierre (5) sont bien sûr telles que, lorsque le chaton et sa pierre enchâssée sont montés sur la bague, l'extrémité de la tige (3) ne soit pas au contact de la face inférieure de la pierre (5).The relative heights of the rod (3) and the stone (5) are of course such that, when the kitten and its embedded stone are mounted on the ring, the end of the rod (3) is not in contact with the underside of the stone (5).
Le dernier degré de liberté du chaton (4) est supprimé par des moyens d'accrochage et de décrochage dudit chaton.The last degree of freedom of the kitten (4) is eliminated by means of hooking and unhooking said kitten.
Ces moyens sont constitués par des ergots (8) placés à l'une des deux extrémités (9) de palmettes (10) qui sont chacune articulées à leur autre extrémité (11) sur le corps (1) de la bague, de part et d'autre de la tige (3), et qui viennent s'insérer dans des anneaux (12) fixés sur la paroi latérale (15) du chaton (4), laquelle paroi latérale (15) s'étend vers le haut depuis la petite base de façon à dissimuler le renflement (7) et éventuellement à dissimuler une petite partie de la pierre (5). La paroi latérale (15) s'étend donc sensiblement jusqu'à mi- hauteur du chaton (4), comme représentée à la Figure 1, voire plus haut, à proximité des griffes (6), si la pierre est elle même peu haute.These means are constituted by lugs (8) placed at one of the two ends (9) of palmettes (10) which are each articulated at their other end (11) on the body (1) of the ring, on both sides and on the other side of the rod (3), and which are inserted into rings (12) fixed on the side wall (15) of the kitten (4), which side wall (15) extends upwards from the small base so as to conceal the bulge (7) and possibly to conceal a small part of the stone (5). The side wall (15) therefore extends substantially up to mid-height of the kitten (4), as shown in Figure 1, or even higher, near the claws (6), if the stone is itself not very high .
Les anneaux (12) sont soudés à la paroi latérale (15) du chaton (4), soit au niveau de la grande base ou bord supérieur (14) de cette paroi, ainsi qu'il est représenté, soit entre cette grande base et le fond du chaton.The rings (12) are welded to the side wall (15) of the kitten (4), either at the level of the large base or upper edge (14) of this wall, as shown, or between this large base and the bottom of the kitten.
Chaque ergot (8) peut être avantageusement constitué par une épingle sertie à la première extrémité (9) de la palmette (10).Each lug (8) can advantageously consist of a pin crimped at the first end (9) of the palmette (10).
Au niveau de l'articulation (11) de chaque palmette (10), le corps de la bague (1) peut présenter un méplat de façon à permetttre une fixation par rivet de la palmette (10) tout en laissant un léger jeu assurant une libre rotation de cette dernière.At the articulation (11) of each palmette (10), the body of the ring (1) may have a flat so as to allow fastening by rivet of the palmette (10) while leaving a slight clearance ensuring a free rotation of the latter.
Selon une autre variante de réalisation, le corps de la bague (1) présente, au niveau des articulations (11), des paliers d'axes et des fentes destinées à recevoir les extrémités des palmettes (10). Dans ce cas, les palmettes (10) sont ainsi articulées sur le corps (1) de la bague par un montage formant charnière.According to another alternative embodiment, the body of the ring (1) has, at the joints (11), axis bearings and slots intended to receive the ends of the palmettes (10). In this case, the palmettes (10) are thus articulated on the body (1) of the ring by a mounting forming a hinge.
La Figure 1 montre le dispositif de fixation selon l'invention en position "ouvert", le chaton (4) étant séparé du corps (1) de la bague et les palmettes (10) relevées. La Figure 2 montre le dispositif de fixation en position "fermé". Le chaton (4) est vissé sur sa tige (3) et les ergots (8) des palmettes (10) sont insérés dans les anneaux (12). Chaque épingle (8) présente avantageusement une protubérance (13) à son extrémité de façon à constituer un moyen de blocage élastique dans l'anneau (12).Figure 1 shows the fixing device according to the invention in the "open" position, the kitten (4) being separated from the body (1) of the ring and the palmettes (10) raised. Figure 2 shows the fixing device in the "closed" position. The kitten (4) is screwed onto its rod (3) and the pins (8) of the palm leaves (10) are inserted into the rings (12). Each pin (8) advantageously has a protuberance (13) at its end so as to constitute an elastic locking means in the ring (12).
La Figure 3 montre comment sont fixés les anneaux (12) sur le chaton (4). Ils sont préférentiellement soudés sur le bord supérieur (14) de la paroi latérale (15) du chaton, sensiblement à mi-hauteur entre les griffes (6) et la base (16) proprement dite (7) du chaton.Figure 3 shows how the rings (12) are attached to the kitten (4). They are preferably welded to the upper edge (14) of the side wall (15) of the kitten, approximately halfway between the claws (6) and the base (16) proper (7) of the kitten.
Les figures 4 à 6 montrent une variante de réalisation du dispositif de fixation qui vient d'être décrit, particulièrement avantageuse en ce qu'elle comprend des moyens de centrage automatique des anneaux (12) du chaton (4) relativement aux palmettes (10) en fin de vissage dudit chaton sur le corps (1) du bijou.Figures 4 to 6 show an alternative embodiment of the fixing device which has just been described, particularly advantageous in that it comprises means for automatic centering of the rings (12) of the kitten (4) relative to the palmettes (10) at the end of screwing said kitten on the body (1) of the jewel.
Cette variante est telle que, en fin de vissage du chaton par l'intermédiaire de la tige filetée (3) et du trou taraudé (7a), la partie basse (17) de l'extrémité libre de chaque anneau (12) vient en contact avec la face supérieure (18) de la partie haute du corps du bijou.This variant is such that, at the end of screwing the kitten via the threaded rod (3) and the tapped hole (7a), the lower part (17) of the free end of each ring (12) comes in contact with the upper face (18) of the upper part of the body of the jewel.
Pour cela, les anneaux (12) sont fortement inclinés vers le bas, par exemple de sorte à faire un angle de l'ordre de 60° avec l'axe du bijou schématisé par la tige filetée (3)For this, the rings (12) are strongly inclined downward, for example so as to make an angle of the order of 60 ° with the axis of the jewel shown diagrammatically by the threaded rod (3)
Chaque anneau (12) est doté d'une échancrure (19) formée à la périphérie dudit anneau, dans sa partie la plus extérieure diamétralement opposée à la partie (20) de fixation de l'anneau sur le chaton (4), ainsi qu'il est particulièrement visible à la Figure 6.Each ring (12) is provided with a notch (19) formed at the periphery of said ring, in its outermost part diametrically opposite to the part (20) for fixing the ring on the kitten (4), as well as '' it is particularly visible in Figure 6.
Pour sa part, le corps (1) du bijou est doté sur sa face supérieure (18) de butées (21) placées au droit des palmettes (10), entre la tige filetée (3) et l'articulation de chaque palmette sur le corps. Ces butées (21), visibles aux Figures 4 et 5, ont une forme allongée et leur largeur est complémentaire de la découpe des échancrures (19) de telle sorte que l'extrémité avant (22) de chaque butée puisse être reçue avec un jeu minimal dans une échancrure.For its part, the body (1) of the jewel is provided on its upper face (18) with stops (21) placed in line with the palmettes (10), between the threaded rod (3) and the articulation of each palmette on the body. These stops (21), visible in Figures 4 and 5, have an elongated shape and their width is complementary to the cutting of the notches (19) so that the front end (22) of each stop can be received with play minimal in a notch.
L'ergot (8) dont est dotée chaque palmette (10) à proximité de son extrémité libre (9) est par exemple une pointe qui, vue de profil à la Figure 4, a une forme (23) en S et, à la manière d'un ressort à lame, elle est douée d'une certaine élasticité vers l'avant et vers l'arrière de la palmette.The lug (8) with which each palmette (10) is provided near its free end (9) is for example a point which, seen in profile in Figure 4, has an S shape (23) and, at the like a leaf spring, it is endowed with a certain elasticity towards the front and towards the rear of the palmette.
Enfin, entre la tige filetée (3) et chaque butée (21), la face supérieure (18) du corps (1) du bijou présente un trou borgne (24) en forme de cuvette sphérique apte à recevoir l'extrémité libre du ressort en S (23).Finally, between the threaded rod (3) and each stop (21), the upper face (18) of the body (1) of the jewel has a blind hole (24) in the form of a spherical cup capable of receiving the free end of the S-shaped spring (23).
Lorsque l'on visse le chaton (4) sur le corps (1) du bijou, en fin de ce vissage, les parties basses (17) des extrémités libres des anneaux (12) viennent en contact avec la face supérieure (18) de la partie haute du corps (1) et lesdits anneaux se verrouillent alors automatiquement par coopération de leurs échancrures (19) qui reçoivent les extrémités (22) des butées (21). Grâce à cette construction, les anneaux (12) sont alors placés exactement dans le prolongement des palmettes en position relevée. Il suffît alors de rabattre lesdites palmettes, dont les ressorts en S (23) passent en se déformant légèrement vers l'avant dans les trous traversants correspondants (25) percés dans les anneaux (12). Lorsque les palmettes viennent à s'appuyer sur les anneaux, les ressorts en S (23) se rabattent élastiquement vers l'arrière et se bloquent sous les anneaux (12), garantissant ainsi un verrouillage supplémentaire. Dans le même temps, les extrémités libres des ressorts en S (23) s'engagent dans les cuvettes (24), créant ainsi un troisième verrouillage.When the kitten (4) is screwed onto the body (1) of the jewel, at the end of this screwing, the lower parts (17) of the free ends of the rings (12) come into contact with the upper face (18) of the upper part of the body (1) and said rings then lock automatically by cooperation of their notches (19) which receive the ends (22) of the stops (21). Thanks to this construction, the rings (12) are then placed exactly in the extension of the palm leaves in the raised position. It then suffices to fold down said palmettes, the S-springs of which (23) pass while being deformed slightly forward in the corresponding through holes (25) drilled in the rings (12). When the palmettes come to bear on the rings, the S springs (23) fold back elastically and lock under the rings (12), thus guaranteeing an additional locking. At the same time, the free ends of the S-shaped springs (23) engage in the cups (24), thereby creating a third lock.
Pour retirer le chaton, en vue de le remplacer par un autre, il suffit de soulever les palmettes une à une avec l'ongle d'un doigt, chaque ressort en S (23) n'offrant alors qu'une résistance insuffisante à l'égard de la force de soulèvement et se relevant élastiquement vers l'avant pour ensuite quitter le trou traversant (25) correspondant dans lequel il était engagé. Les palmettes étant basculées vers l'arrière, il suffit ensuite de dévisser le chaton, le verrouillage des butées (21) du corps du bijou dans les échancrures (19) n'offrant également qu'une résistance insuffisante à l'égard de la force de rotation exercée par le porteur du bijou.To remove the kitten, in order to replace it with another, it suffices to lift the palmettes one by one with the nail of a finger, each S-shaped spring (23) then offering only insufficient resistance to the with regard to the lifting force and rising resiliently forward and then leaving the corresponding through hole (25) in which it was engaged. The palmettes being tilted backwards, it then suffices to unscrew the kitten, the locking of the stops (21) of the body of the jewel in the notches (19) also offering only insufficient resistance with regard to the force of rotation exerted by the wearer of the jewel.
Comme il va de soi, l'invention ne se limite pas à la seule description technique ci-dessus, donnée à titre d'exemple, et elle embrasse au contraire toutes les variantes. Il en est ainsi notamment du bijou auquel elle est adaptée, la bague décrite ci-dessus n'étant donnée qu'à titre d'exemple. Dans son application à certains bijoux, notamment à un collier, un pendentif ou à un sautoir, le chaton dans lequel est enchâssée la pierre pourra être assemblé audit bijou par l'intermédiaire de trois, voire quatre palmettes par exemple, disposées alors respectivement à 120° ou à 90° les unes relativement aux autres. Il en est également ainsi des premiers moyens de restriction des degrés de liberté du chaton. La tige filetée (3) peut en effet être soudée sous la base (16) du chaton, le bijou (1) ou la pièce rapportée (2) soudée au bijou étant alors percé d'un orifice dont le taraudage est complémentaire du filetage de ladite tige. It goes without saying that the invention is not limited to the sole technical description above, given by way of example, and on the contrary embraces all the variants. This is particularly the case for the jewel to which it is adapted, the ring described above being given only by way of example. In its application to certain jewels, in particular to a necklace, a pendant or a long necklace, the kitten in which the stone is set can be assembled to said jewel by means of three, even four palmettes for example, then arranged respectively at 120 ° or 90 ° relative to each other. This is also the case with the first means of restricting the kitten's degrees of freedom. The threaded rod (3) can indeed be welded under the base (16) of the kitten, the jewel (1) or the insert (2) welded to the jewel then being pierced with an orifice whose tapping is complementary to the thread of said rod.
