Chaîne ornementale composée d'éléments successifs ayant chacun une forme générale sphérique.Ornamental chain made up of successive elements each having a generally spherical shape.
La présente invention concerne une chaîne ornementale composée d'éléments successifs ayant chacun une forme générale sphérique par exemple.The present invention relates to an ornamental chain composed of successive elements each having a general spherical shape for example.
Il est connu de réaliser une chaîne dite à boules au moyen d'un procédé consistant à repousser à intervalles réguliers la matière d'un fil métallique pour former des zones élargies présentant un rétrécissement de section à mi-longueur, de les envelopper chacune par une feuille de métal conformée en boule puis de casser ensuite le fil au niveau du rétré- cissement de chaque zone élargie à l'intérieur des boules.It is known to produce a so-called ball chain by means of a process consisting in pushing the material of a metal wire at regular intervals to form enlarged zones having a narrowing in section at mid-length, to wrap them each with a sheet of metal shaped into a ball then break the wire at the level of the narrowing of each enlarged zone inside the balls.
Ce procédé n'est pas particulièrement bien adapté à la réalisation d'une chaîne ornementale, notamment car les boules ainsi réalisées ne se prêtent pas aisément au sertissage de pierres précieuses.This process is not particularly well suited to the production of an ornamental chain, in particular because the balls thus produced do not readily lend themselves to the setting of precious stones.
On connaît par le brevet français FR-1 237 084 un collier de perles dont chaque perle comporte une pièce rapportée, élastiquement déformable, présentant un rebord destiné à retenir la tête d'un organe de liaison relié à une perle adjacente. Cette pièce rapportée se présente sous la forme d'un manchon fendu longitudinalement. Lors de la mise en place de la tête de l'organe de liaison, le manchon peut se déformer élastiquement. Un tel collier de perles n'offre pas entière satisfaction. En particulier, la pièce rapportée peut s'avérer dif- ficile à réaliser dans certains cas du fait que le rebord tend à s'opposer à sa déformation élastique. Il existe de plus un risque de détachement des perles en cas de forte traction exercée accidentellement sur le collier.French patent FR-1 237 084 discloses a pearl necklace, each pearl of which has an elastically deformable insert, having a flange intended to retain the head of a connecting member connected to an adjacent pearl. This insert is in the form of a longitudinally split sleeve. When placing the head of the connecting member, the sleeve can deform elastically. Such a pearl necklace is not entirely satisfactory. In particular, the insert can prove difficult to produce in certain cases because the flange tends to oppose its elastic deformation. There is also a risk of detachment of the beads in the event of strong traction accidentally exerted on the necklace.
La présente invention a pour objet une chaîne ornementale dans laquelle l'un au moins des éléments successifs qui la composent comporte un corps creux à l'intérieur du- quel est fixé un insert conformé pour retenir un organe de liaison relié à un élément adjacent de la chaîne, cet insert étant constitué par au moins un manchon.The subject of the present invention is an ornamental chain in which at least one of the successive elements which compose it comprises a hollow body inside which is fixed a shaped insert for retaining a connecting member connected to an adjacent element of the chain, this insert being constituted by at least one sleeve.
De façon caractéristique, le manchon comporte une fente suffisamment large pour permettre le passage du corps de l'organe de liaison.Typically, the sleeve has a slot wide enough to allow passage of the body of the connecting member.
Grâce à l'invention, chaque élément de la chaîne tel que défini ci-dessus n'est pas en prise directement avec l'organe de liaison.Thanks to the invention, each element of the chain as defined above is not engaged directly with the connecting member.
C'est l'insert fixé à l'intérieur du corps creux qui sert à retenir l'organe de liaison.It is the insert fixed inside the hollow body which serves to retain the connecting member.
Cela élargit le choix des matériaux pouvant être utilisés pour réaliser le corps creux.This widens the choice of materials that can be used to make the body hollow.
L'invention autorise également une grande diversité de formes de réalisation de ce corps creux.The invention also allows a wide variety of embodiments of this hollow body.
Le sertissage d'une pierre précieuse sur l'élément est en outre facilité puisque le corps creux peut être conformé pour recevoir une pièce de support spécifique.The setting of a precious stone on the element is also facilitated since the hollow body can be shaped to receive a specific support piece.
Dans une réalisation particulière, le corps creux est sphérique et il est avantageusement réalisé par décolletage. ce qui permet d'obtenir un aspect de surface particulièrement esthétique.In a particular embodiment, the hollow body is spherical and it is advantageously produced by bar turning. which provides a particularly aesthetic surface appearance.
Toujours dans une réalisation particulière, l'insert est fixé dans un perçage tra- versant le corps creux.Still in a particular embodiment, the insert is fixed in a hole passing through the hollow body.
L'insert peut être retenu par ajustement serré à l'intérieur du corps creux.The insert can be retained by a tight fit inside the hollow body.
L'insert peut ne présenter aucune élasticité sensible vers l'extérieur.The insert may have no appreciable elasticity towards the outside.
Lorsque l'on désire monter une pierre précieuse sur l'élément, le corps creux comporte de préférence un perçage borgne d'axe perpendiculaire à celui de l'insert pour re- cevoir une pièce de support de cette pierre.When it is desired to mount a precious stone on the element, the hollow body preferably comprises a blind bore with an axis perpendicular to that of the insert to receive a support piece for this stone.
Un autre objet de l'invention est d'utiliser la pièce de support précitée pour améliorer le maintien d'un insert servant à retenir un organe de liaison dans le corps creux d'un élément de la chaîne.Another object of the invention is to use the aforementioned support piece to improve the maintenance of an insert serving to retain a connecting member in the hollow body of an element of the chain.
Dans une réalisation particulière, cette pièce de support présente une fourchette conformée pour s'engager à cheval sur l'insert, lequel présente avantageusement un rétrécissement de sa section extérieure. Cette pièce de support peut ainsi participer au maintien de l'insert dans le corps creux de l'élément.In a particular embodiment, this support piece has a shaped fork for engaging astride the insert, which advantageously has a narrowing of its outer section. This support piece can thus participate in maintaining the insert in the hollow body of the element.
Dans une réalisation particulière, l'insert et l'organe de liaison sont conformés de telle sorte que ce dernier est retenu dans l'insert avec une possibilité de rotation autour de l'axe de l'insert. De préférence, l'insert et l'organe de liaison sont conformés de telle sorte que ce dernier est retenu dans l'insert avec une possibilité de déplacement selon l'axe de l'insert. Avantageusement, l'organe de liaison comporte une tête élargie à son extrémité retenue dans l'insert et ce dernier présente un rétrécissement de sa section intérieure. De préférence, l'insert est constitué par deux manchons fendus longitudinalement et présentant chacun un rétrécissement de sa section intérieure. Ces manchons sont avantageusement conformés pour s'emboîter l'un dans l'autre. L'organe de liaison peut être constitué par un pion à deux têtes, dont la longueur est comprise entre 2 et 20 mm par exemple.In a particular embodiment, the insert and the connecting member are shaped so that the latter is retained in the insert with a possibility of rotation about the axis of the insert. Preferably, the insert and the connecting member are shaped so that the latter is retained in the insert with a possibility of displacement along the axis of the insert. Advantageously, the connecting member comprises an enlarged head at its end retained in the insert and the latter has a narrowing of its internal section. Preferably, the insert consists of two sleeves split longitudinally and each having a narrowing of its internal section. These sleeves are advantageously shaped to fit into one another. The connecting member can be constituted by a pin with two heads, the length of which is between 2 and 20 mm for example.
Dans une autre réalisation particulière, l'organe de liaison est monté dans fin- sert avec une possibilité de pivotement selon un axe d'articulation perpendiculaire à l'axe de l'insert. Avantageusement, l'organe de liaison présente un corps de section transversale rectangulaire, de grands côtés perpendiculaires à l'axe d'articulation précité et pourvu de deux perçages à ses extrémités, chacun pour le passage d'une cheville. De préférence, cha- que cheville est engagée par ses extrémités dans des perçages réalisés sur l'insert. lequel peut être monobloc.In another particular embodiment, the connecting member is mounted in fin- serves with a possibility of pivoting along an axis of articulation perpendicular to the axis of the insert. Advantageously, the connecting member has a body of rectangular cross section, long sides perpendicular to the aforementioned articulation axis and provided with two holes at its ends, each for the passage of a dowel. Preferably, each dowel is engaged by its ends in holes made on the insert. which can be in one piece.
Avantageusement, l'insert présente à ses extrémités axiales des surfaces, sphé- riques par exemple, se situant dans le prolongement de la surface extérieure du corps creux, ce qui est intéressant du point de vue esthétique. D'autres caractéristiques et avantages de la présente invention ressortiront à la lecture de la description détaillée qui va suivre, d'exemples de réalisation non limitatifs de l'invention, et à l'examen du dessin annexé, sur lequel :Advantageously, the insert has surfaces at its axial ends, spherical for example, lying in the extension of the external surface of the hollow body, which is advantageous from an aesthetic point of view.

Le manchon femelle 8 présente une surface extérieure symétrique de révolution autour de l'axe X, pourvue d'un épaulement 12 qui délimite du côté de l'extrémité 10 une surface 13 cylindrique de révolution dont le diamètre correspond sensiblement à celui du perçage 5 du corps creux 3 et du côté de l'extrémité 14 opposée une surface 15 également cylindrique de révolution dont le diamètre est inférieur à celui de la surface 13. Le manchon mâle 9 présente une surface extérieure symétrique de révolution, pourvue d'épaulements 17 et 18 qui définissent entre eux une surface 19 cylindrique de révolution dont le diamètre est le même que celui de la surface 15 du manchon femelle 8.These sleeves 8 and 9 have spherical surfaces respectively referenced 10 and 11 at an axial end, which are located once the insert 7 in place inside the hollow body 3 in the extension of the spherical surface 4 of the latter, as can be seen in Figure 1. The female sleeve 8 has a symmetrical outer surface of revolution around the axis X, provided with a shoulder 12 which delimits on the side of the end 10 a cylindrical surface 13 of revolution whose the diameter corresponds substantially to that of the bore 5 of the hollow body 3 and on the side of the opposite end 14 a surface 15 also cylindrical of revolution whose diameter is less than that of the surface 13. The male sleeve 9 has a symmetrical outer surface of revolution, provided with shoulders 17 and 18 which define between them a cylindrical surface 19 of revolution whose diameter is the same as that of the surface 15 female sleeve 8.
L'épaulement 18 délimite, du côté de l'extrémité 1 1. une surface 20 cylindrique de révolution dont le diamètre est le même que celui de la surface 13 du manchon femelle 8.The shoulder 18 delimits, on the side of the end 1 1. a cylindrical surface 20 of revolution whose diameter is the same as that of the surface 13 of the female sleeve 8.
L'épaulement 17 délimite, du côté de l'extrémité opposée 16. une surface 21 cylindrique de révolution dont le diamètre est inférieur à celui de la surface 19.The shoulder 17 delimits, on the side of the opposite end 16. a cylindrical surface 21 of revolution whose diameter is less than that of the surface 19.
La section intérieure du manchon mâle 9 présente un diamètre constant dans une région 25 s'étendant sur une majeure partie de sa longueur et se rétrécit en 26 au voisinage de l'extrémité 1 1.The inner section of the male sleeve 9 has a constant diameter in a region 25 extending over most of its length and narrows at 26 in the vicinity of the end 11.
La section intérieure du manchon femelle 8 est étagée et se rétrécit en 22 au voisinage de l'extrémité 10. Le diamètre intérieur de l'embouchure du manchon femelle 8 au niveau de l'extrémité 14 correspond à celui de la surface 21 du manchon mâle de sorte que les manchons 8 et 9 peuvent s'emboîter pour constituer l'insert 7, les épaulements 13 et 17 venant en appui l'un contre l'autre.The inner section of the female sleeve 8 is stepped and narrows at 22 near the end 10. The inside diameter of the mouth of the female sleeve 8 at the end 14 corresponds to that of the surface 21 of the male sleeve so that the sleeves 8 and 9 can fit together to form the insert 7, the shoulders 13 and 17 coming to bear against one another.
Le diamètre de la section intérieure du manchon femelle 8 dans la région 23 intermédiaire entre le rétrécissement 22 et l'embouchure 24 est égal à celui de la section intérieure du manchon mâle 9 au niveau de l'extrémité 16.The diameter of the internal section of the female sleeve 8 in the region 23 intermediate between the constriction 22 and the mouth 24 is equal to that of the internal section of the male sleeve 9 at the end 16.
Les diamètres des rétrécissements 22 et 26 sont égaux.The diameters of the constrictions 22 and 26 are equal.
Deux éléments 2 successifs sont reliés entre eux par un élément de liaison qui se présente dans l'exemple de réalisation décrit sous la forme d'un pion 30 comportant un corps 32 cylindrique de révolution et à ses extrémités deux têtes 31 d'un plus grand diamètre.Two successive elements 2 are connected together by a connecting element which is presented in the embodiment described in the form of a pin 30 comprising a cylindrical body 32 of revolution and at its ends two heads 31 of a larger diameter.
On peut réaliser par exemple le pion 30 à partir d'un fil métallique en repoussant localement et à intervalles réguliers la matière de ce fil pour former des zones élargies présentant chacune à mi-longueur un rétrécissement de section puis en sectionnant le fil au niveau de ces rétrécissements.One can for example make the pin 30 from a metal wire by locally pushing at regular intervals the material of this wire to form enlarged zones each having at mid-length a narrowing of section then by cutting the wire at the level of these narrowing.
Le diamètre du corps 32 est légèrement inférieur à celui des rétrécissements 22 et 26 tandis que le diamètre des régions 23 et 25 est légèrement supérieur à celui des têtes 31.The diameter of the body 32 is slightly less than that of the constrictions 22 and 26 while the diameter of the regions 23 and 25 is slightly greater than that of the heads 31.
Les manchons 8 et 9 sont fendus axialement sur toute leur longueur dans l'exemple décrit pour permettre l'introduction dans chacun de la tête 31 d'un pion 30, comme illustré sur les figures 5 et 7.The sleeves 8 and 9 are split axially over their entire length in the example described to allow the introduction into each of the head 31 of a pin 30, as illustrated in FIGS. 5 and 7.
Dans le cas du manchon femelle 8, la tête 31 est introduite par l'extrémité 14, l'axe du corps 32 étant alors sensiblement perpendiculaire à l'axe X, puis le pion 30 est déplacé parallèlement à lui-même jusqu'à ce que la tête 31 vienne buter contre le rétrécisse- ment 22.In the case of the female sleeve 8, the head 31 is introduced through the end 14, the axis of the body 32 then being substantially perpendicular to the axis X, then the pin 30 is moved parallel to itself until that the head 31 comes to abut against the constriction 22.
Ensuite le pion 30 est pivoté d'un quart de tour pour prendre la position représentée en pointillés sur la figure 5, le corps 32 étant alors sensiblement coaxial avec l'axe X. _ £ _Then the pin 30 is pivoted a quarter turn to take the position shown in dotted lines in Figure 5, the body 32 then being substantially coaxial with the axis X. _ £ _
La largeur d'ouverture de la fente 33 réalisée sur le manchon femelle 8 est légèrement supérieure au diamètre du corps 32 du pion 30.The opening width of the slot 33 produced on the female sleeve 8 is slightly greater than the diameter of the body 32 of the pin 30.
De même, le pion 30 est mis en place dans le manchon mâle 9 en introduisant la tête 31 par l'extrémité 16, l'axe du corps 32 étant alors sensiblement perpendiculaire à l'axe X, puis en faisant glisser le pion 30 parallèlement à lui-même jusqu'à ce que la tête 31 vienne buter contre le rétrécissement 26.Likewise, the pin 30 is put into place in the male sleeve 9 by introducing the head 31 through the end 16, the axis of the body 32 then being substantially perpendicular to the axis X, then sliding the pin 30 parallel to itself until the head 31 abuts against the narrowing 26.
Le pion 30 est ensuite pivoté d'un quart de tour de manière à amener le corps 32 dans l'axe X du manchon 2, comme illustré sur la figure 7 en pointillés.The pin 30 is then pivoted by a quarter turn so as to bring the body 32 in the axis X of the sleeve 2, as illustrated in FIG. 7 in dotted lines.
Une fois les têtes 31 des pions 30 en place dans les manchons 8 et 9, ces der- niers sont introduits par leurs extrémités 14 et 16 dans le perçage 5. comme illustré sur la figure 6, et s'emboîtent l'un dans l'autre pour constituer l'insert 7, comme on peut le voir sur la figure 10.Once the heads 31 of the pins 30 are in place in the sleeves 8 and 9, the latter are introduced by their ends 14 and 16 into the bore 5. as illustrated in FIG. 6, and fit one into the 'other to constitute the insert 7, as can be seen in Figure 10.
De préférence, l'emboîtement des manchons 8 et 9 s'effectue avec un ajustement serré de telle sorte que ceux-ci restent assemblés par friction. Les manchons 8 et 9 peuvent ne présenter aucune élasticité notable.Preferably, the fitting of the sleeves 8 and 9 is carried out with a tight fit so that they remain assembled by friction. The sleeves 8 and 9 may have no significant elasticity.
Les manchons 8 et 9 sont retenus à l'intérieur du perçage 5 par ajustement serré d'une part de la surface 13 du manchon mâle 8 et d'autre part de la surface 20 du manchon mâle 9.The sleeves 8 and 9 are retained inside the bore 5 by tight fitting on the one hand from the surface 13 of the male sleeve 8 and on the other hand from the surface 20 of the male sleeve 9.
Bien entendu, on ne sort pas du cadre de la présente invention en réalisant l'as- semblage des manchons 8 et 9 et leur fixation dans le corps creux 3 par soudure ou par tout autre moyen conventionnel.Of course, it is not going beyond the ambit of the present invention to produce the sleeves 8 and 9 and to fix them in the hollow body 3 by welding or by any other conventional means.
Dans l'exemple de réalisation décrit, une pierre précieuse 45 est sertie sur chaque élément 2 au moyen d'une pièce de support 40 représentée isolément sur la figure 11.In the embodiment described, a precious stone 45 is set on each element 2 by means of a support piece 40 shown in isolation in FIG. 11.
Cette pièce de support 40 se présente sous la forme d'un corps cylindrique de révolution évidé en partie inférieure pour former une fourchette 41 destinée à s'engager à cheval sur l'insert 7 et évidée en partie supérieure pour former un logement conique 42.This support piece 40 is in the form of a cylindrical body of revolution hollowed out in the lower part to form a fork 41 intended to engage astride the insert 7 and hollowed out in the upper part to form a conical housing 42.
La largeur d'ouverture de la fourchette 41 correspond au diamètre des surfaces 13 et 20.The opening width of the fork 41 corresponds to the diameter of the surfaces 13 and 20.
Le diamètre de la pièce de support 40 correspond à celui du perçage borgne 6 de telle sorte qu'elle s'y trouve maintenue par ajustement serré.The diameter of the support piece 40 corresponds to that of the blind bore 6 so that it is held there by tight adjustment.
Le logement 42 est surmonté par une mince paroi 44 destinée à être repoussée sur le dessus de la pierre 45 lors de l'opération de sertissage.The housing 42 is surmounted by a thin wall 44 intended to be pushed back on top of the stone 45 during the crimping operation.
Le fond 43 du logement 42 est percé pour permettre une fois la pièce de sup- port 40 insérée sans la pierre 45 dans le corps creux 3 de réaliser une fraisure 46 dans l'insert 7 pour recevoir l'extrémité intérieure de la pierre 45.The bottom 43 of the housing 42 is pierced to allow the support part once port 40 inserted without the stone 45 in the hollow body 3 to make a countersink 46 in the insert 7 to receive the inner end of the stone 45.
L'engagement de la fourchette 41 sur l'insert 7 s'effectue avec friction, ce qui procure à la fois une force de retenue supplémentaire de la pièce de support 40 et de l'insert 7 à l'intérieur du corps creux 3 et renforce la tenue de l'assemblage des manchons 8 et 9.The engagement of the fork 41 on the insert 7 takes place with friction, which provides both an additional retaining force of the support piece 40 and of the insert 7 inside the hollow body 3 and strengthens the strength of the assembly of sleeves 8 and 9.
On a représenté sur la figure 13 un élément 2 tel que précédemment décrit, assemblé par un pion 30 à un élément d'extrémité 2' qui diffère de l'élément 2 par le fait que le corps creux 3' et la pièce de support 40' sont légèrement plus gros et par le fait que le perçage 5 n'est pas traversant mais borgne et accueille un insert 7' monobloc. Plus particulièrement, cet insert 7' est constitué ici par un manchon dont la section intérieure présente un rétrécissement, monté avec ajustement serré dans le perçage 5 et fendu longitudinalement pour le montage de la tête 31 du pion 30. à l'instar des manchons 8 et 9 précédemment décrits.FIG. 13 shows an element 2 as previously described, assembled by a pin 30 to an end element 2 ′ which differs from element 2 in that the hollow body 3 ′ and the support piece 40 'are slightly larger and by the fact that the bore 5 is not through but blind and accommodates an insert 7' in one piece. More particularly, this insert 7 ′ is constituted here by a sleeve, the inner section of which has a narrowing, mounted with tight fit in the bore 5 and split longitudinally for mounting the head 31 of the pin 30. like the sleeves 8 and 9 previously described.
De préférence, comme représenté, les pions 30 sont retenus avec un certain jeu à l'intérieur des inserts 7 et 7' et les éléments successifs de la chaîne disposent ainsi d'une possibilité de rotation entre eux autour de l'axe X et de translation selon cet axe X.Preferably, as shown, the pins 30 are retained with a certain play inside the inserts 7 and 7 'and the successive elements of the chain thus have a possibility of rotation between them around the axis X and of translation along this axis X.
On peut grâce à cette mobilité obtenir des effets esthétiques intéressants, les orientations relatives des pierres n'étant alors jamais figées.Thanks to this mobility, it is possible to obtain interesting aesthetic effects, the relative orientations of the stones then never being fixed.
L'insert fixé dans le corps creux d'un élément 2 ou 2' peut servir, sans que l'on sorte du cadre de la présente invention, à retenir une extrémité d'un organe de liaison relié à l'autre extrémité à une chaîne à boules obtenue par le procédé conventionnel rappelé au début.The insert fixed in the hollow body of an element 2 or 2 'can be used, without departing from the scope of the present invention, to retain one end of a connecting member connected at the other end to a ball chain obtained by the conventional process mentioned at the beginning.
Dans l'exemple de réalisation des figures 14 à 20. les éléments 2" de la chaîne comportent chacun un corps creux 3 identique à celui-ci représenté sur la figure 2. Ce corps creux reçoit un insert 7" représenté isolément sur la figure 18 et une pièce de support 40 identique à celle précédemment décrite en référence à la figure 11.In the embodiment of Figures 14 to 20. the elements 2 "of the chain each have a hollow body 3 identical to that shown in Figure 2. This hollow body receives an insert 7" shown in isolation in Figure 18 and a support piece 40 identical to that previously described with reference to FIG. 11.
Les éléments 2" sont réunis par des organes de liaison 50 avec une possibilité de rotation selon un axe d'articulation Z perpendiculaire à l'axe X des inserts 7".The elements 2 "are joined by connecting members 50 with the possibility of rotation along an axis of articulation Z perpendicular to the axis X of the inserts 7".
Plus particulièrement, chaque organe de liaison 50 comporte un corps 51 de section transversale rectangulaire, de grands côtés perpendiculaires à l'axe d'articulation Z, pourvu à ses deux extrémités de perçages 52 dans lesquels sont engagées des chevilles 53 venant en prise à leurs extrémités dans des perçages 54 de l'insert 7". Les axes des perçagesMore particularly, each connecting member 50 comprises a body 51 of rectangular cross section, long sides perpendicular to the axis of articulation Z, provided at its two ends with holes 52 in which are engaged pins 53 engaging their ends in holes 54 of insert 7 ". The axes of the holes
54 coupent perpendiculairement l'axe X. L'insert 7" présente extérieurement la même géométrie que l'insert 7 représenté sur la figure 10. à l'exception des perçages 54. Il est traversé axialement par une fente 58. qui s'étend dans l'exemple décrit sur toute sa longueur, et présente un rétrécissement 59 de sa section extérieure. La fente 58 a, dans l'exemple décrit, une section transversale rectan- gulaire. de grands côtés perpendiculaires aux axes des perçages 54. La profondeur de la fente 58 correspond sensiblement aux trois quarts du plus grand diamètre extérieur de l'insert 7".54 intersect the X axis perpendicularly. The insert 7 "externally has the same geometry as the insert 7 shown in Figure 10. with the exception of the holes 54. It is axially crossed by a slot 58. which extends in the example described over its entire length, and has a narrowing 59 of its outer section The slot 58 has, in the example described, a rectangular cross section, long sides perpendicular to the axes of the holes 54. The depth of the slot 58 corresponds substantially to the three quarters of the largest outside diameter of the insert 7 ".
On ne sort pas du cadre de l'invention en ne fendant l'insert 7" longitudinalement qu'à ses extrémités axiales, sur une distance juste suffisamment longue pour permet- tre d'engager les organes de liaison 50.It is not going beyond the scope of the invention by splitting the insert 7 "longitudinally only at its axial ends, over a distance just long enough to enable the connecting members 50 to be engaged.
Dans une variante de réalisation non représentée, l'insert n'est pas fendu longitudinalement sur toute sa longueur mais seulement à ses extrémités axiales.In an alternative embodiment not shown, the insert is not split longitudinally over its entire length but only at its axial ends.
Dans ce cas. l'insert peut présenter à chacune de ses extrémités axiales une fente qui s'étend sur toute la hauteur de l'insert. le traversant verticalement. La géométrie de la pierre éventuellement fixée sur la boule dans laquelle est engagé l'insert tient alors compte du faut que l'insert n'est pas fendu longitudinalement sur toute sa longueur.In that case. the insert may have at each of its axial ends a slot which extends over the entire height of the insert. crossing it vertically. The geometry of the stone possibly fixed on the ball in which the insert is engaged then takes into account the need that the insert is not split longitudinally over its entire length.
Il faut donner au terme fente employé dans la présente description un sens large, la fente pouvant présenter une section transversale qui ne comporte pas nécessaire- ment deux côtes parallèles.The term slit used in the present description should be given a broad meaning, the slit possibly having a cross section which does not necessarily have two parallel ribs.
Dans une variante de réalisation non représentée, la fente permettant le montage de l'extrémité de l'organe de liaison ne débouche pas sur la surface latérale de l'insert mais seulement sur la surface d'extrémité de l'insert, destinée à venir dans le prolongement de la surface extérieure du corps creux. Pour assembler les éléments 2", on commence par insérer les extrémités de deux organes de liaison 50 dans la fente 58 de l'insert 7", par exemple en les introduisant suivant l'axe X de l'insert 7", pour faire coïncider les perçages 52 et 54, puis on introduit les chevilles 53 dans ceux-ci. On suppose que l'un des organes de liaison 50 est déjà assemblé à un élément 2" et que l'autre est libre. L'insert 7" est ensuite introduit dans le perçage 5 du corps 3 puis la pièce de support 40 est mise en place, la fourchette 41 venant s'engager sur le rétrécissement de section 59 précité.In an alternative embodiment not shown, the slot allowing the end of the connecting member to be mounted does not open onto the lateral surface of the insert but only onto the end surface of the insert, intended to come in the extension of the external surface of the hollow body. To assemble the elements 2 ", one begins by inserting the ends of two connecting members 50 in the slot 58 of the insert 7", for example by introducing them along the axis X of the insert 7 ", to make them coincide the holes 52 and 54, then the plugs 53 are inserted therein. It is assumed that one of the connecting members 50 is already assembled to a 2 "element and that the other is free. The insert 7 "is then introduced into the bore 5 of the body 3 then the support part 40 is put in place, the fork 41 coming to engage on the narrowing of section 59 above.
Le mode de réalisation des figures 14 à 20 permet de maintenir les pierres dans une orientation donnée autour de l'axe X des inserts.The embodiment of Figures 14 to 20 keeps the stones in an orientation given around the X axis of the inserts.
Bien entendu, on ne sort pas du cadre de la présente invention en modifiant la nature et la géométrie des éléments successifs composant la chaîne, ces derniers pouvant ne pas accueillir de pierres précieuses, les corps creux des éléments pouvant être réalisés avec des perles par exemple. Of course, it is not going beyond the scope of the present invention by modifying the nature and the geometry of the successive elements making up the chain, the latter possibly not receiving precious stones, the hollow bodies of the elements being able to be produced with pearls for example .
