Domaine technique Technical area
[0001] La présente invention concerne une bague joaillière configurée pour pouvoir s'accommoder sur des doigts de différentes tailles. Plus particulièrement, la présente invention concerne une bague joaillière comprenant une ou plusieurs plaquettes d'ajustement coopérant avec un dispositif ressort. Etat de la technique The present invention relates to a jeweler ring configured to accommodate on fingers of different sizes. More particularly, the present invention relates to a jewelery ring comprising one or more adjustment plates cooperating with a spring device. State of the art
[0002] Il est connu qu'à l'achat d'une bague il y a lieu en général de modifier les mesures pour l'adapter au doigt qui doit la porter. Le cas n'est pas rare qu'il faille par la suite encore la modifier pour l'adapter à la variation de la circonférence de ce doigt comme c'est le cas d'un enfant qui croît, un adulte qui engraisse ou maigrit, etc. Les opérations  It is known that the purchase of a ring is usually to change the measures to adapt it to the finger that must wear it. The case is not uncommon that it must be further modified to adapt to the variation of the circumference of this finger as is the case of a child who grows, an adult fattening or losing weight, etc. The operations
d'agrandissement ou de rétrécissement d'une bague sont assez simples, mais entraînent toujours une perte de temps et une dépense. Il y a ensuite des cas où ces opérations ne peuvent être faites, comme par exemple pour les alliances avec pierres précieuses où une modification de la circonférence comporte une modification du nombre de pierres. Comme les dimensions habituellement employées pour les bagues sont d'une vingtaine, dans le dernier cas d'alliances avec brillants, le commerçant doit tenir à la The enlargement or narrowing of a ring is quite simple, but always involves a waste of time and expense. Then there are cases where these operations can not be done, as for example for gemstone rings where a change in circumference involves a change in the number of stones. As the dimensions usually used for rings are twenty, in the last case of alliances with brilliants, the trader must keep to the
disposition de sa clientèle une vingtaine de dimensions impliquant une immobilisation importante de capital et compte tenu aussi que les alliances avec pierres précieuses peuvent être très variées comme modèle. Its clientele has around twenty dimensions, which implies a significant capital outlay, and also that alliances with precious stones can be very varied as a model.
[0003] Une bague joaillière comprenant un dispositif pour accommoder la taille des doigts, dans lequel le dispositif incorpore des plaquettes montées amovibles radialement dans le corps de la bague, est connue.A jewelery ring comprising a device for accommodating the size of the fingers, in which the device incorporates plates removably mounted radially in the body of the ring, is known.
Dans ce type de bague, une force élastique est exercée sur les plaquettes afin qu'elles puissent s'étendre dans l'ouverture centrale de la bague pour adapter la taille de cette ouverture au doigt du porteur. Bref résumé de l’invention In this type of ring, an elastic force is exerted on the pads so that they can extend into the central opening of the ring to adapt the size of this opening to the wearer's finger. Brief summary of the invention
[0004] La présente invention concerne une bague joaillière configurée pour pouvoir s'accommoder sur des doigts de différentes tailles,  The present invention relates to a jewelry ring configured to accommodate on fingers of different sizes,
comprenant: un corps de bague ayant une ouverture sensiblement annulaire et destinée à recevoir le doigt, le corps de bague comportant au moins un logement communiquant avec l'ouverture; au moins une plaquette d'ajustement montée mobile dans le logement et s'étendant sur un segment angulaire le long du corps de bague; un dispositif ressort configuré pour exercer une force élastique sur la plaquette d'ajustement de sorte que cette dernière peut être déplacée le long d'un axe sensiblement radial par rapport au corps de bague, la bague étant configurable entre une première configuration dans laquelle un diamètre interne de comprising: a ring body having a substantially annular opening and for receiving the finger, the ring body having at least one housing communicating with the opening; at least one adjustment wafer mounted movably in the housing and extending over an angular segment along the ring body; a spring device configured to exert an elastic force on the adjustment wafer so that the latter can be moved along a substantially radial axis with respect to the ring body, the ring being configurable between a first configuration in which a diameter internal
l'ouverture de la bague est maximal et sensiblement égal au diamètre de la face intérieure du corps du bague et au moins une seconde configuration dans laquelle le diamètre interne de l'ouverture de la bague est réduit et défini, au moins en partie, par la plaquette d'ajustement qui fait saillie de la face intérieure du corps du bague ; le dispositif ressort étant monté à la plaquette d'ajustement de manière amovible par des moyens de sertissage. the opening of the ring is maximum and substantially equal to the diameter of the inner face of the ring body and at least a second configuration in which the internal diameter of the opening of the ring is reduced and defined, at least in part, by the adjustment plate which protrudes from the inner face of the ring body; the spring device being mounted to the adjustment plate removably by crimping means.
[0005] Selon un mode de réalisation, le dispositif ressort est configuré pour exercer la force élastique sensiblement au centre du segment angulaire formé par la plaquette d'ajustement. According to one embodiment, the spring device is configured to exert the elastic force substantially in the center of the angular segment formed by the adjustment plate.
[0006] Le montage du dispositif ressort sur la plaquette d'ajustement par des moyens de sertissage permet d'obtenir une bague dans laquelle les propriétés mécanique (et élastiques) du dispositif ressort restent inchangées par rapport aux propriétés du dispositif ressort isolé. En particulier, les moyens de sertissage permettent au dispositif ressort monté sur la plaquette d'ajustement de conserver sa dureté et ses propriétés élastiques inchangées, par rapport au dispositif ressort non monté, tout en assurant un contact fiable et une bonne coopération entre le dispositif ressort et la plaquette d'ajustement. Mounting the spring device on the adjustment plate by crimping means provides a ring in which the mechanical properties (and elastic) of the spring device remain unchanged from the properties of the isolated spring device. In particular, the crimping means allow the spring device mounted on the adjustment plate to retain its hardness and its elastic properties unchanged, compared to the unmounted spring device, while ensuring a reliable contact and good cooperation between the spring device. and the adjustment wafer.
[0007] Le document US2012180523 décrit un anneau comportant une partie ajustable sur sa surface intérieure, matérialisée par une languette insérée dans le corps de l'anneau, et articulée par l'une de ses extrémités. Une lame de ressort pousse la languette vers l'extérieur de la surface de l'anneau. Il décrit alternativement une plaquette d'ajustement insérée dans le corps de l'anneau et poussée hors de la surface interne par deux ressorts spirale. US2012180523 discloses a ring having an adjustable portion on its inner surface, materialized by a tongue inserted into the body of the ring, and articulated by one of its extremities. A leaf spring pushes the tongue outward from the surface of the ring. It alternately describes an adjustment plate inserted into the body of the ring and pushed out of the inner surface by two spiral springs.
[0008] Le document US2787142 décrit un anneau dans l'épaisseur duquel est insérée une plaquette d'ajustement, dont la surface est poussée à l'extérieur de la surface interne de l'anneau au moyen d'un ressort. US2787142 discloses a ring in the thickness of which is inserted an adjustment plate, the surface is pushed outside the inner surface of the ring by means of a spring.

Exemple(s) de mode de réalisation de l’invention Example (s) of embodiment of the invention
[0010] La figure 1 montre une vue en perspective et la figure 2 montre une vue du dessus d'une bague joaillière 1 configurée pour pouvoir s'accommoder sur des doigts de différentes tailles, selon un mode de réalisation.  Figure 1 shows a perspective view and Figure 2 shows a top view of a jeweler ring 1 configured to accommodate on fingers of different sizes, according to one embodiment.
[0011] En particulier, les figures 1 et 2 montrent un corps de bague 10 comportant une ouverture 16 sensiblement annulaire et destinée à recevoir le doigt. Le corps de bague 10 comprend trois plaquettes d'ajustement 21 qui sont de préférence disposées le long de la circonférence du corps de bague 1, sur sa face intérieure 17. In particular, Figures 1 and 2 show a ring body 10 having a substantially annular opening 16 and intended to receive the finger. The ring body 10 comprises three adjustment plates 21 which are preferably arranged along the circumference of the ring body 1, on its inner face 17.
[0012] Dans cette forme d'exécution privilégiée, l'agencement des trois plaquettes d'ajustement 21 peut permettre un mouvement combiné de translation et rotation de la bague 1 sur le doigt, au besoin. In this preferred embodiment, the arrangement of the three adjustment plates 21 may allow a combined movement of translation and rotation of the ring 1 on the finger, if necessary.
[0013] Chacune des plaquettes d'ajustement 21 s'étend sur un segment angulaire le long du corps de bague 10. La plaquette d'ajustement 21 est pourvue d'une surface de contact 25 venant en contact avec le doigt lorsque la bague 1 est portée. Chacune des plaquettes d'ajustement 21 est configurée pour se déplacer le long d'un axe 11 sensiblement radial par rapport au corps de bague 10 (dans les figures 1 et 2, ce déplacement est indiqué par la flèche D). En particulier, chacune des plaquettes Each of the adjustment plates 21 extends over an angular segment along the ring body 10. The adjustment plate 21 is provided with a contact surface 25 coming into contact with the finger when the ring 1 is worn. Each of the adjustment pads 21 is configured to move along a substantially radial axis 11 with respect to the ring body 10 (in FIGS. 1 and 2, this displacement is indicated by the arrow D). In particular, each of the platelets
d'ajustement 21 est configurée pour se déplacer le long de l'axe 11 entre une première configuration dans laquelle le diamètre interne de 21 is configured to move along the axis 11 between a first configuration in which the internal diameter of
l'ouverture 16 de la bague 1 a une valeur maximale sensiblement égale au diamètre de la face intérieure 17 du corps du bague 10 (la surface de la plaquette est sensiblement à fleur avec la face 17), et au moins une seconde configuration dans laquelle le diamètre interne de l'ouverture 16 de la bague est réduit et défini, au moins en partie, par la plaquette the opening 16 of the ring 1 has a maximum value substantially equal to the diameter of the inner face 17 of the body of the ring 10 (the surface of the wafer is substantially flush with the face 17), and at least one second configuration in which the internal diameter of the opening 16 of the ring is reduced and defined, at least in part, by the plate
d'ajustement 21 qui fait saillie de la face intérieure 17 du corps du bague 10. 21 which protrudes from the inner face 17 of the body of the ring 10.
[0014] De la sorte, les plaquettes d'ajustement 21 permettent d'adapter le diamètre interne de la bague 1 au doigt, dans les limites du déplacement des plaquettes mobiles 21. In this way, the adjustment plates 21 make it possible to adapt the internal diameter of the ring 1 to the finger, within the limits of the displacement of the movable plates 21.
[0015] La figure 3 montre une vue en perspective de la bague joaillière 1 dans laquelle le corps de bague 10 est représenté écorché à l'extérieur de manière à visualiser des éléments de la bague 1 qui seraient autrement cachés par le corps de bague 10. En particulier, la figure 3 permet de voir un logement 12 compris dans le corps de bague 10 et dans lequel est montée l'une des plaquettes d'ajustement 21. Dans l'exemple illustré aux figures 1 à 3, le corps de bague 10 comporte trois logements 12, dans chacun desquels est monté une plaquette d'ajustement 21. Figure 3 shows a perspective view of the jewelery ring 1 in which the ring body 10 is shown cut away on the outside so as to display elements of the ring 1 which would otherwise be hidden by the ring body 10 In particular, FIG. 3 shows a housing 12 included in the ring body 10 and in which is mounted one of the adjustment plates 21. In the example illustrated in FIGS. 1 to 3, the ring body 10 comprises three housings 12, in each of which is mounted an adjustment plate 21.
[0016] Le logement 12 communique avec l'ouverture 16 sur la face intérieure 17 du corps de bague 10. Chaque plaquette d'ajustement 21 se déplace donc le long de l'axe 11 à l'intérieur du logement 12 de sorte à faire saillir plus ou moins par rapport à la face intérieure 17, entre la première et ladite au moins une seconde configuration, et modifier ainsi le diamètre interne de la bague 1. The housing 12 communicates with the opening 16 on the inner face 17 of the ring body 10. Each adjustment plate 21 moves along the axis 11 inside the housing 12 so as to make protruding more or less with respect to the inner face 17 between the first and the said at least one second configuration, and thus modifying the internal diameter of the ring 1.
[0017] La figure 3 permet également de voir un dispositif ressort 20 coopérant avec la plaquette d'ajustement 21 de manière à exercer une force élastique sur la plaquette d'ajustement 21 dirigée le long de l'axe radial 11 , vers le centre 13 du corps de bague 10. Figure 3 also shows a spring device 20 cooperating with the adjustment plate 21 so as to exert an elastic force on the adjustment plate 21 directed along the radial axis 11 towards the center 13 of the ring body 10.
[0018] Selon une forme préférée, le dispositif ressort comprend une lame-ressort 20. La lame-ressort 20 s'étend sur un segment angulaire le long du corps de bague 10. Dans l'exemple particulier illustré aux figures 3 et 4, la lame-ressort 20 s'étend sensiblement parallèle à la plaquette d'ajustement 21. According to a preferred form, the spring device comprises a leaf spring 20. The leaf spring 20 extends over an angular segment along the ring body 10. In the particular example illustrated in FIGS. 3 and 4, the leaf spring 20 extends substantially parallel to the adjustment plate 21.
[0019] la figure 4 montre une vue isolée d'une plaquette d'ajustement 21 sur laquelle est montée la lame-ressort 20. Avantageusement selon l'invention, comme illustrée par cette forme de réalisation, la lame-ressort 20 est monté de manière amovible sur la plaquette d'ajustement 21 par des moyens de sertissage 24. De préférence, les moyens de sertissage 24 agissent sur le centre de la plaquette d'ajustement 21. [0019] FIG. 4 shows an insulated view of an adjustment plate 21 on which the leaf spring 20 is mounted. Advantageously according to the invention, as illustrated by this embodiment, the leaf spring 20 is assembled from Removable manner on the adjustment plate 21 by crimping means 24. Preferably, the crimping means 24 act on the center of the adjustment plate 21.
[0020] Dans l'exemple préféré illustré aux figures 3 et 4, les moyens de sertissage comprennent au moins une paire de pattes 24 (ou griffes) rabattables venant solidariser le centre de la lame-ressort 20 sur la plaquette d'ajustement 21 lorsque les pattes 24 sont rabattues. De manière avantageuse, les pattes 24 sont rabattables par déformation élastique. [0021] Tous autres moyens de fixation de la lame-ressort 20 à la plaquette d'ajustement 21 dans la mesure où la lame-ressort 20 est montée à la plaquette d'ajustement 21 de façon amovible (voire une fixation non permanente permettant de démonter le ressort sans endommager le ressort ou la plaquette) peut être envisagés. Par exemple, la lame-ressort 20 peut être fixée à la plaquette d'ajustement 21 par clipsage. In the preferred example illustrated in Figures 3 and 4, the crimping means comprise at least one pair of tabs 24 (or claws) folds coming to secure the center of the spring blade 20 on the adjustment plate 21 when the legs 24 are folded. Advantageously, the tabs 24 are foldable by elastic deformation. All other fastening means of the spring blade 20 to the adjustment plate 21 to the extent that the spring blade 20 is mounted to the adjustment plate 21 removably (or a non-permanent attachment to disassemble the spring without damaging the spring or plate) may be considered. For example, the leaf spring 20 can be attached to the adjustment plate 21 by clipping.
[0022] Le montage de la lame-ressort 20 de manière amovible sur la plaquette d'ajustement 21 plutôt que par soudage ou d'autres moyens de fixation permanents permet de conserver une dureté inchangée de la lame- ressort 20. De cette façon, la lame-ressort 20 conserve ses propriétés élastiques tout en assurant un contact fiable et une bonne coopération entre la lame-ressort 20 et la plaquette d'ajustement 21, avec une bonne répartition de forces. The mounting of the spring blade 20 removably on the adjustment plate 21 rather than by welding or other permanent fixing means makes it possible to maintain an unchanged hardness of the leaf spring 20. In this way, the spring blade 20 retains its elastic properties while ensuring reliable contact and good cooperation between the leaf spring 20 and the adjustment plate 21, with a good distribution of forces.
[0023] Dans le mode de réalisation illustré à la figure 4, la lame-ressort 20 est de forme cintrée ayant une première zone d'inflexion 31 In the embodiment illustrated in Figure 4, the leaf spring 20 is of curved shape having a first inflection zone 31
sensiblement au centre du segment angulaire formé par la lame-ressort 20. Les moyens de sertissage 24 peuvent alors avantageusement solidariser la lame-ressort 20 au niveau de la première zone d'inflexion 31. Dans cette configuration, la lame-ressort 20 exerce la force élastique sensiblement au centre du segment angulaire formé par la plaquette d'ajustement 21. substantially at the center of the angular segment formed by the leaf spring 20. The crimping means 24 can then advantageously secure the leaf spring 20 at the first inflection zone 31. In this configuration, the leaf spring 20 exerts the elastic force substantially at the center of the angular segment formed by the adjustment plate 21.
[0024] Toujours en référence à la figure 4, la lame-ressort 20 comprend une seconde zone d'inflexion 32 à chacune des extrémités du segment angulaire formé par la lame-ressort 20. Still with reference to FIG. 4, the leaf spring 20 comprises a second zone of inflection 32 at each of the ends of the angular segment formed by the leaf spring 20.
[0025] Les secondes zones d'inflexion 32 sont destinées à venir en appui contre une paroi supérieure 14 du corps de bague 10, au fond du logement 12 tout en restant libres de déplacer radialement le long de la paroi supérieure 14. The second inflection zones 32 are intended to bear against an upper wall 14 of the ring body 10, at the bottom of the housing 12 while remaining free to move radially along the upper wall 14.
[0026] Dans un mode de réalisation, la bague 1 comprend au moins un capot 40 configuré pour venir se fixer au corps de bague 10 de manière à retenir la plaquette d'ajustement 21 dans le logement 12. Plus particulièrement, le capot 40 sert de butée limitant le déplacement de la plaquette d'ajustement 21 le long de l'axe radial 11, vers le centre 13 du corps de bague 10. In one embodiment, the ring 1 comprises at least one cover 40 configured to be fixed to the ring body 10 so as to retain the adjustment plate 21 in the housing 12. More in particular, the cap 40 serves as a stop limiting the displacement of the adjustment plate 21 along the radial axis 11 towards the center 13 of the ring body 10.
[0027] En référence au mode de réalisation particulier des figures 3 et 4, la plaquette d'ajustement 21 comporte une zone de chevauchement 22 à chacune de ses extrémités. Au moins une portion du capot 40 peut alors venir en appui sur la zone de chevauchement 22 lorsque le capot 40 est fixé au corps de bague 10. Lors de la fixation du capot 40 au corps de bague 10, au moins une portion du capot 40 peut venir en appui sur la zone de chevauchement 22, de sorte que la une portion du capot 40 joue le rôle de la butée limitant le déplacement de la plaquette d'ajustement 21 le long de l'axe radial 11, vers le centre 13 du corps de bague 10. With reference to the particular embodiment of Figures 3 and 4, the adjustment plate 21 has an overlapping zone 22 at each of its ends. At least a portion of the cover 40 can then bear on the overlap zone 22 when the cover 40 is fixed to the ring body 10. When fixing the cover 40 to the ring body 10, at least a portion of the cover 40 can bear on the overlap zone 22, so that a portion of the cover 40 acts as the stop limiting the displacement of the adjustment plate 21 along the radial axis 11 towards the center 13 of the ring body 10.
[0028] D'autres configurations de la zone de chevauchement 22 peuvent également être envisagées. Par exemple, la plaquette d'ajustement 21 peut ne comporter qu'une seule zone de chevauchement 22 à l'une de ses extrémités. Alternativement, ou de façon complémentaire, la zone de chevauchement 22 pourrait s'étendre sur au moins l'un des côtés latéraux 23 de la plaquette d'ajustement 21. Other configurations of the overlap zone 22 may also be envisaged. For example, the adjustment plate 21 may have only one overlapping zone 22 at one of its ends. Alternatively, or in a complementary manner, the overlap zone 22 could extend on at least one of the lateral sides 23 of the adjustment plate 21.
[0029] Un montage des capots 40 par vissage permet de facilement les démonter du corps de bague 10, par exemple pour faciliter les opérations d'entretien. Alternativement, les capots 40 peuvent être soudés, par exemple au laser, sur le corps de bague 10. Mounting hoods 40 by screwing allows easy disassembly of the ring body 10, for example to facilitate maintenance operations. Alternatively, the covers 40 may be welded, for example by laser, to the ring body 10.
[0030] Selon une forme d'exécution avantageuse, au moins l'un de la plaquette d'ajustement 21, la lame-ressort 20, le capot 40 et le corps de la bague 10 est fabriqué dans métal précieux, tel que l'or ou un tel alliage. De manière privilégiée, tous ces composants sont fabriqués dans un métal précieux. According to an advantageous embodiment, at least one of the adjustment plate 21, the leaf spring 20, the cap 40 and the body of the ring 10 is manufactured in precious metal, such as the gold or such an alloy. In a preferred way, all these components are made of a precious metal.
[0031] Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme de métier sans sortir du cadre de la présente invention. It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and Simple variants may be contemplated by those skilled in the art without departing from the scope of the present invention.
[0032] Par exemple, le dispositif d'ajustement peut comporter moins de trois plaquettes d'ajustement 21, voir plus de trois plaquettes d'ajustement 21. Dans les exemples illustrés, les plaquettes d'ajustement 21 s'étendant en général longitudinalement en arc de cercle, de sorte à être plus ou moins conforme avec la forme du corps de bague 10. Cependant, les plaquettes d'ajustement 21 pourraient avoir une autre forme (par exemple avec une surface plutôt plate qu'en arc de cercle) dans la mesure où elles peuvent remplir leur rôle d'accommoder des doigts de différentes tailles. Ces agencements alternatifs peuvent également permettre un mouvement combiné de translation et rotation de la bague 1 sur le doigt, au besoin. For example, the adjustment device may comprise less than three adjustment plates 21, see more than three adjustment plates 21. In the illustrated examples, the adjustment plates 21 extending generally longitudinally in FIG. circular arc, so as to be more or less in accordance with the shape of the ring body 10. However, the adjustment plates 21 could have another shape (for example with a flat surface rather than an arc) in to the extent that they can fulfill their role of accommodating fingers of different sizes. These alternative arrangements may also allow a combined movement of translation and rotation of the ring 1 on the finger, if necessary.
[0033] Dans le dispositif d'ajustement décrit ici, la plaquette In the adjustment device described here, the plate
d'ajustement 21, qui se déplace dans le logement 12 du corps de bague 10, n'entre généralement pas en contact avec des surfaces internes du corps de bague 10, c'est-à-dire mis à part avec des saillies de guidage 50 pourvues sur les parois latérales 15 du logement 12 tel que l'est décrit ci-dessous par rapport à la figure 5. En effet, la plaquette d'ajustement 21 n'est liée mécaniquement au corps de bague 10 que par l'intermédiaire du dispositif ressort 20. Les frottements qui pourraient s'opposer à la force élastique du dispositif ressort 20 et créer une usure des pièces sont ainsi minimaux. 21, which moves in the housing 12 of the ring body 10, does not generally come into contact with internal surfaces of the ring body 10, that is to say, except with guiding projections 50 provided on the side walls 15 of the housing 12 as described below with respect to Figure 5. Indeed, the adjustment plate 21 is mechanically connected to the ring body 10 only through 20. The friction that could oppose the elastic force of the spring device 20 and create wear parts are thus minimal.
[0034] Encore dans un autre mode réalisation illustré à la figure 5, la bague 1 comprend un dispositif de guidage configuré pour guider le déplacement de la plaquette d'ajustement 21 sensiblement au centre du segment angulaire formé par la plaquette d'ajustement 21, et selon l'axe radial 11. In yet another embodiment illustrated in FIG. 5, the ring 1 comprises a guiding device configured to guide the displacement of the adjustment plate 21 substantially at the center of the angular segment formed by the adjustment plate 21. and along the radial axis 11.
[0035] Selon un mode de réalisation, le dispositif de guidage comprend au moins une encoche 51 pourvue sur la plaquette d'ajustement 21, l'encoche 51 coopérant avec au moins une saillie 50 pourvue dans le logement 12. [0036] Dans l'exemple particulier de la figure 5, le dispositif de guidage comprend une encoche 51 sur chacun des côtés latéraux 23 de la plaquette d'ajustement 21. Chacune des encoches 51 coopère avec une saillie 50 pourvue sur chacune des parois latérales 15 du logement 12. De According to one embodiment, the guiding device comprises at least one notch 51 provided on the adjustment plate 21, the notch 51 cooperating with at least one projection 50 provided in the housing 12. In the particular example of Figure 5, the guide device comprises a notch 51 on each of the lateral sides 23 of the adjustment plate 21. Each of the notches 51 cooperates with a projection 50 provided on each of the side walls 15 of housing 12. From
préférence, les côtés latéraux 23 et les parois latérales 15 sont dans un plan sensiblement parallèle au plan de la bague 1 (par plan de la bague, on entend un plan coupant la bague en deux anneaux symétriques, l'axe radial 11 de la plaquette d'ajustement 21 se trouvant dans ce plan). preferably, the lateral sides 23 and the side walls 15 are in a plane substantially parallel to the plane of the ring 1 (plane of the ring means a plane intersecting the ring in two symmetrical rings, the radial axis 11 of the plate of adjustment 21 lying in this plane).
[0037] Toujours dans l'exemple particulier de la figure 5, les surfaces de contact entre l'encoche 51 et de la saillie 50 sont définies, respectivement, par l'épaisseur 53 des côtés latéraux 23 de la plaquette d'ajustement 21 et par l'épaisseur 52 d'un côté flanc de la saillie 50. Les frottements des surfaces de contact peuvent être minimisés en améliorant les Still in the particular example of Figure 5, the contact surfaces between the notch 51 and the projection 50 are defined, respectively, by the thickness 53 of the lateral sides 23 of the adjustment plate 21 and by the thickness 52 of a side flank of the projection 50. The friction of the contact surfaces can be minimized by improving the
caractéristiques tribologiques des surfaces de contact définissant les épaisseurs 52, 53. tribological characteristics of the contact surfaces defining the thicknesses 52, 53.
[0038] Chacun des côtés latéraux 23 de la plaquette d'ajustement 21 peut comprendre plus d'une encoche 51 coopérant avec plus d'une saillie 50 pourvues sur chacune des parois latérales 15 du logement 12. Each of the lateral sides 23 of the adjustment plate 21 may comprise more than one notch 51 cooperating with more than one projection 50 provided on each of the side walls 15 of the housing 12.
[0039] Avantageusement, la saillie 50 peut servir également de butée, limitant un déplacement radial et angulaire de la plaquette d'ajustement 21. Advantageously, the projection 50 can also serve as a stop, limiting a radial and angular displacement of the adjustment plate 21.
[0040] La forme des saillies 50 et des encoches 51 peut être The shape of the projections 50 and notches 51 can be
complémentaire de façon à réduire le jeu dans le guidage. Le dispositif de guidage central permet d'assurer un déplacement lisse et sûr de la complementary to reduce play in the guidance. The central guiding device ensures a smooth and safe movement of the
plaquette mobile 21 par rapport au corps de bague 10. movable plate 21 with respect to the ring body 10.
[0041] Le dispositif de guidage décrit ci-dessus permet à la plaquette d'ajustement 21 de se déplacer de manière fiable sans se coincer dans le logement 12. Un avantage du dispositif de guidage est qu'il est de construction simple, nécessitant peu de pièces pour effectuer un bon guidage. Le dispositif de guidage est également caractérisé par des petites surfaces de contact, limitant ainsi les frottements. The guiding device described above allows the adjustment plate 21 to move reliably without getting caught in the housing 12. An advantage of the guiding device is that it is of simple construction, requiring little of coins to make a good guide. The guiding device is also characterized by small contact surfaces, thus limiting friction.
[0042] Une méthode d'assemblage de la bague 1 peut comprendre de monter de manière amovible le dispositif ressort 20 sur la plaquette d'ajustement 21. Une fois que le dispositif ressort 20 est monté sur la plaquette d'ajustement 21, cette dernière est positionnée dans le logement 12. Un capot 40 est alors fixé au corps de bague 10 de manière à retenir la plaquette d'ajustement 21 dans le logement 12. A method of assembling the ring 1 may comprise removably mount the spring device 20 on the adjustment plate 21. Once the spring device 20 is mounted on the adjustment plate 21, the latter is positioned in the housing 12. A cover 40 is then attached to the ring body 10 so as to retain the adjustment plate 21 in the housing 12.
[0043] La bague 1 de l'invention évite des retouches habituelles sur des bagues normales et réduit considérablement le nombre d'alliances avec pierres précieuses à stocker et à la disposition du client, car en pratique avec seulement quatre dimensions on arrive à couvrir toute une gamme de diamètre pour l'ouverture 16. Selon un mode de réalisation, la seconde zone d'inflexion 32 peut se déplacer librement par rapport à la paroi supérieure 14. The ring 1 of the invention avoids the usual retouching on normal rings and significantly reduces the number of rings with precious stones to store and available to the client, because in practice with only four dimensions we can cover all a diameter range for the opening 16. According to one embodiment, the second inflection zone 32 can move freely with respect to the upper wall 14.
