Abstract

The jewellery, such as a ring or bracelet, has an external ring which is able to turn between two lateral annular edges of a concentric internal ring. The internal ring is constituted by a soldered assembly of two half rings of the same diameter, the same external configuration and same axial length. Each half ring is formed from an annular part (3,4) comprising, from an end edge, a bulge (3b,4b) which forms a side retaining strip for the external ring. They also have a cylindrical annular part (3c,4c) able to engage in the external ring. Each of the annular parts, at its opposite end edge, has a tubular part (3e,4e) of reduced thickness relative to the thickness of the annular cylindrical part . The reduced thickness parts extend from the internal surface (3a) and from the external surface of the cylindrical annular parts. They thus define, when the two annular parts are abutted to form an internal ring, an internal annular cavity able to receive the solder.

Description

La présente invention est relative à un bijou annulaire tel qu'une bague ou un bracelet comportant une couronne extérieure rotative.The present invention relates to an annular jewel such than a ring or bracelet with an outer crown rotary.

On connaít depuis très longtemps de tels bijoux en matières précieuses, en particulier en or, dont la couronne extérieure peut tourner entre deux bordures latérales annulaires d'une couronne intérieure concentrique à la couronne extérieure.We have known for a long time such jewelry material precious, in particular gold, whose outer crown can rotate between two annular side edges of a crown inner concentric to the outer crown.

La couronne intérieure comporte, entre les deux bordures, une portée cylindrique sur laquelle est engagée la couronne extérieure, le diamètre intérieur de la couronne extérieure étant légèrement supérieur au diamètre extérieur de la portée cylindrique de la couronne intérieure de manière à permettre la rotation de ladite couronne extérieure.The inner crown has, between the two borders, a cylindrical bearing surface on which the crown is engaged outer, the inner diameter of the outer ring being slightly greater than the outside diameter of the cylindrical seat of the inner crown so as to allow the rotation of said outer crown.

Différentes configurations de tels bijoux annulaires ont déjà été proposées, ainsi que différents procédés pour les fabriquer, notamment par expansion ou par soudure.Different configurations of such annular jewelry have already proposed, as well as different processes for manufacturing them, in particular by expansion or by welding.

On connaít ainsi par EP-A-0 529 168 un bijou annulaire dans lequel la couronne intérieure est usinée avec une portée centrale de plus grand diamètre et deux portées latérales sur lesquelles sont soudés des anneaux séparés constituant les bordures latérales.We thus know from EP-A-0 529 168 an annular jewel in which the inner crown is machined with a central reach of larger diameter and two lateral spans on which are welded separate rings constituting the side edges.

Pour réaliser un tel bijou annulaire, il est nécessaire d'usiner, pour former la couronne intérieure, trois composants séparés, puis de mettre en oeuvre deux opérations de soudure pour fixer chacun des anneaux latéraux sur les portées latérales correspondantes de la couronne intérieure.To make such an annular jewel, it is necessary to machine, to form the inner crown, three components separate and then implement two welding operations to fix each of the side rings on the side spans of the inner crown.

La présente invention se propose de perfectionner une telle réalisation en ne nécessitant, pour la fabrication de la couronne intérieure, que deux éléments gui au surplus peuvent être obtenus à partir d'ébauches identiques, et qui peuvent être assemblés en ne mettant en oeuvre qu'une seule opération de soudure.The present invention proposes to perfect such a realization by not requiring, for the manufacture of the crown interior, that two additional elements can be obtained at from identical blanks, which can be assembled without using only one welding operation.

La présente invention se caractérise essentiellement par le fait que la couronne intérieure est constituée par l'assemblage soudé de deux demi-couronnes présentant le même diamètre intérieur, la même configuration extérieure et sensiblement la même étendue axiale, chacune des demi-couronnes étant formée d'un élément annulaire comportant, à partir d'un bord d'extrémité, une portée en renflement apte à former un bourrelet latéral de retenue pour la couronne extérieure et une portée annulaire cylindrique apte à s'engager dans la couronne extérieure, chacun desdits éléments annulaires comportant, à son bord d'extrémité opposé, une portée tubulaire d'épaisseur réduite par rapport à l'épaisseur de ladite portée annulaire cylindrique, lesdites portées tubulaires d'épaisseur réduite s'étendant à partir de la surface intérieure et respectivement de la surface extérieure desdites portées cylindriques annulaires de manière à définir, lorsque les deux éléments annulaires sont amenés en butée pour former la couronne intérieure, une cavité annulaire interne apte à recevoir un matériau de soudure.The present invention is essentially characterized by the fact that the inner crown is formed by the welded assembly two half-rings with the same inside diameter, the same external configuration and substantially the same axial extent, each of the half-rings being formed of an annular element having, from an end edge, a bulging bearing suitable for forming a lateral retaining bead for the crown external and a cylindrical annular bearing capable of engaging in the outer ring, each of said annular elements comprising, at its opposite end edge, a thick tubular seat reduced compared to the thickness of said annular seat cylindrical, said tubular bearing surfaces of reduced thickness extending from the interior surface and respectively from the outer surface of said annular cylindrical bearing surfaces so to be defined, when the two annular elements are brought into abutment to form the inner crown, an internal annular cavity suitable to receive a weld material.

A l'état assemblé, les portées tubulaires d'extrémité des éléments annulaires sont emboítées l'une dans l'autre et une continuité de surface intérieure et extérieure est assurée pour les portées cylindriques des deux éléments annulaires qui constituent la portée cylindrique de la couronne intérieure sur laquelle peut tourner la couronne extérieure.In the assembled state, the tubular end bearings of the annular elements are fitted one inside the other and a interior and exterior surface continuity is ensured for cylindrical bearings of the two annular elements which constitute the cylindrical bearing surface of the inner ring on which can rotate the outer crown.

D'autres avantages et caractéristiques de l'invention apparaítront à la lecture de la description qui suit d'un exemple de réalisation nullement limitatif en se référant au dessin annexé dans lequel :

  • La figure 1 est une vue en coupe des composants d'un bijou annulaire selon l'invention avant assemblage,
  • la figure 2 est une vue en coupe des mêmes composants après assemblage,
  • la figure 3 est une vue en perspective éclatée correspondant à la disposition illustrée à la figure 1.
Other advantages and characteristics of the invention will appear on reading the following description of an exemplary embodiment which is in no way limitative with reference to the appended drawing in which:
  • FIG. 1 is a sectional view of the components of an annular jewel according to the invention before assembly,
  • FIG. 2 is a sectional view of the same components after assembly,
  • FIG. 3 is an exploded perspective view corresponding to the arrangement illustrated in FIG. 1.

Le bijou annulaire selon l'invention, tel qu'une bague par exemple, comporte une couronne extérieure 1 présentant une surface intérieure cylindrique 2, évidée dans l'exemple illustré mais qui pourrait être pleine.The annular jewel according to the invention, such as a ring by example, has an outer ring 1 having a surface cylindrical interior 2, hollowed out in the example illustrated but which could be full.

Une couronne intérieure est constituée par l'assemblage de deux éléments annulaires 3 et 4 présentant chacun une surface intérieure cylindrique 3a et respectivement 4a, de même diamètre, et une surface extérieure comportant une portée en renflement 3b et respectivement 4b s'étendant de préférence depuis un bord d'extrémité de l'élément correspondant 3 et respectivement 4.An inner ring is formed by the assembly of two annular elements 3 and 4 each having a cylindrical inner surface 3 a and respectively 4 a , of the same diameter, and an outer surface having a bulging surface 3 b and 4 b s' respectively. preferably extending from an end edge of the corresponding element 3 and 4 respectively.

La couronne extérieure 1 et les éléments 3, 4 formant la couronne extérieure sont par exemple réalisés en or préalablement fondu pour présenter le titre désire.The outer ring 1 and the elements 3, 4 forming the outer crown are for example made of gold beforehand fade to present the desired title.

Les portées en renflement sont prolongées en direction du bord opposé de chacun des éléments 3 et 4, par des portées annulaires cylindriques 3c et respectivement 4c, de même épaisseur, dont les surfaces extérieures 3d et 4d présentent un même diamètre légèrement inférieur au diamètre de la surface intérieure 2 de la couronne extérieure 1.The bulging spans are extended in the direction of the opposite edge of each of the elements 3 and 4, by cylindrical annular spans 3 c and 4 c respectively, of the same thickness, whose outer surfaces 3 d and 4 d have the same slightly smaller diameter the diameter of the inner surface 2 of the outer ring 1.

La portée 3c de l'élément annulaire 3 comporte à son extrémité libre une portée tubulaire 3e d'épaisseur réduite par rapport à l'épaisseur de la portée 3c .The bearing surface 3 c of the annular element 3 comprises at its free end a tubular bearing surface 3 e of reduced thickness compared to the thickness of the bearing surface 3 c .

La portée tubulaire 3e s'étend à partir de la surface intérieure 3a de l'élément 3, en saillie vers l'avant par rapport au bord d'extrémité de la surface supérieure 3d de cet élément 3.The tubular surface 3 e extends from the inner surface 3 a of the element 3, projecting forward relative to the end edge of the upper surface 3 d of this element 3.

L'élément 4 comporte pour sa part une portée tubulaire d'extrémité 4e d'épaisseur réduite par rapport à l'épaisseur de la portée 4c et s'étendant depuis la surface extérieure 4d de la portée 4c.The element 4 comprises for its part a tubular end bearing 4 e of reduced thickness compared to the thickness of the bearing 4 c and extending from the outer surface 4 d of the bearing 4 c .

La portée tubulaire 4e en saillie constitue le bord d'extrémité libre de la portée 4c.The projecting tubular surface 4 e constitutes the free end edge of the surface 4 c .

Les portées tubulaires 3e et 4e présentent la même extension radiale.Tubular bearings 3 e and 4 e have the same radial extension.

Les portées tubulaires 3e et 4e présentent de préférence la même épaisseur, la somme des épaisseurs de ces portées tubulaires 3e et 4e étant inférieure a l'épaisseur des portées 3d et 4d, de manière que, lorsque les éléments annulaires 3 et 4 sont amenés en butée mutuelle, comme illustré à la figure 2, à l'intérieur de la couronne 1 il se forme entre les portées tubulaires 3e et 4e une cavité annulaire 5 apte à être remplie d'un matériau de soudure comme illustré à la figure 2, pour assurer l'assemblage des éléments 3 et 4 à l'intérieur de la couronne 1.The tubular spans 3 e and 4 e preferably have the same thickness, the sum of the thicknesses of these tubular spans 3 e and 4 e being less than the thickness of the spans 3 d and 4 d , so that, when the annular elements 3 and 4 are brought into mutual abutment, as illustrated in FIG. 2, inside the crown 1 an annular cavity 5 is formed between the tubular bearings 3 e and 4 e capable of being filled with a welding material as illustrated in Figure 2, to ensure the assembly of elements 3 and 4 inside the crown 1.

Un joint de soudure unique est ainsi réalisé sensiblement au milieu de la couronne extérieure 1 et est formé dans l'épaisseur de la couronne intérieure constituée par l'assemblage des éléments 3 et 4 et est de ce fait parfaitement invisible.A single weld joint is thus produced substantially at middle of the outer ring 1 and is formed in the thickness of the inner crown formed by the assembly of elements 3 and 4 and is therefore perfectly invisible.

Les éléments 3 et 4 peuvent être réalisés séparément par usinage, ou en variante peuvent être formés à partir d'ébauches identiques obtenues dans un même moule et dont les extrémités amenées à venir en regard sont usinées de manière à obtenir la conformation illustrée.Elements 3 and 4 can be made separately by machining, or alternatively can be formed from blanks identical obtained in the same mold and whose ends brought coming next are machined so as to obtain the conformation illustrated.

Dans l'exemple illustré, la largeur de la couronne extérieure 1 est inférieure à la largeur de la portée cylindrique ménagée entre les portées en renflement 3b et 4b des éléments 3 et 4 assemblés permettant un mouvement latéral de la couronne extérieure 1 en plus de son mouvement de rotation.In the example illustrated, the width of the outer ring 1 is less than the width of the cylindrical seat formed between the swelling spans 3 b and 4 b of the elements 3 and 4 assembled allowing lateral movement of the outer ring 1 in addition of its rotational movement.
