Description

La présente invention concerne un bracelet avec des maillons articulés, notamment pour montre. On connaît déjà de tels bracelets dans lesquels les maillons sont articulés sur des axes métalliques (DE-A 2 744 370). Dans ce cas, et au cours du porté, il se produit généralement et peu à peu une usure des articulations produisant du jeu entre les maillons du bracelet, ce qui influence la mise de longueur de celui-ci et le rend désagréable au porté.The present invention relates to a bracelet with articulated links, in particular for a watch. We already know such bracelets in which the links are articulated on metal axes (DE-A 2 744 370). In this case, and during wearing, there is generally and gradually wear of the joints producing play between the links of the bracelet, which influences the length setting of the latter and makes it unpleasant to wear.

En conséquence, la présente invention se propose de réaliser un bracelet avec des maillons articulés ne présentant pas le défaut de prendre du jeu même après une longue période d'utilisation. Pour atteindre ce but, le bracelet selon la présente invention est réalisé comme décrit dans la revendication 1. Par le fait que les maillons sont articulés sur des éléments de grande dureté, par exemple des rubis, l'usure est pratiquement nulle et aucun jeu ne peut prendre naissance. En outre, les articulations sur rubis ou similaires sont extrêmement libres et il n'existe pratiquement pas de risque de grippage.Consequently, the present invention proposes to produce a bracelet with articulated links which do not have the defect of taking play even after a long period of use. To achieve this object, the bracelet according to the present invention is produced as described in claim 1. By the fact that the links are articulated on elements of great hardness, for example rubies, the wear is practically zero and no play is possible. can arise. In addition, the joints on rubies or the like are extremely free and there is practically no risk of seizure.

L'invention va être décrite ci-dessous à l'aide de différentes formes d'exécution illustrées dans le dessin dans lequel:

  • La figure 1 est une coupe longitudinale à travers une première forme d'exécution de l'articulation des maillons du bracelet,
  • La figure 2 est une coupe transversale d'un maillon du bracelet,
  • La figure 3 est une coupe longitudinale à travers une deuxième forme d'exécution de l'articulation des maillons du bracelet, et
  • Les figures 4 à 6 montrent différentes variantes de montage des éléments de grande dureté sur l'axe de l'articulation.
The invention will be described below using different embodiments illustrated in the drawing in which:
  • FIG. 1 is a longitudinal section through a first embodiment of the articulation of the links of the bracelet,
  • FIG. 2 is a cross section of a link of the bracelet,
  • FIG. 3 is a longitudinal section through a second embodiment of the articulation of the links of the bracelet, and
  • Figures 4 to 6 show different variants of mounting the elements of high hardness on the axis of the joint.

La figure 1 montre en 1 les parties extérieures d'un premier maillon du bracelet articulé avec la partie centrale 2 du maillon adjacent. Comme indiqué en figure 2, les maillons sont divisés en deux parties a et b dans le sens de la hauteur, ces parties étant superposées et soudées entre elles par point après la mise en place de l'axe, dans le bracelet terminé. Les maillons 1 et 2 sont assemblés par une articulation comprenant un axe 3 disposé entre les parties extérieures 1 du premier maillon et traversant la partie centrale 2 du second maillon. Dans les parties 1, l'axe 3 s'engage avec jeu dans un logement 4. Dans la forme d'exécution illustrée en figure 1, l'axe se termine de chaque côté par une portée et un pivot 5. L'axe comporte en outre dans sa partie centrale des gorges 6 dans lesquelles sont engagés des renflements 7 de la partie centrale 2 du maillon adjacent. Ces gorges et renflements empêchent l'axe de se déplacer axialement. Les renflements 7 indiqués en figure 1 sont ceux de la partie inférieure a du maillon adjacent 2. Sur les pivots 5 se trouve un élément de grande dureté 8, par exemple un rubis, formant palier pour l'axe 3, c'est-à-dire que le pivot tourne librement dans les éléments 8 qui sont pressés dans le logement 4. Un capuchon 9 avec un trou borgne vient épauler l'élément 8 et ferme le logement 4. Lors du montage, les éléments 8 sont d'abord disposés sur les pivots 5, puis l'axe ainsi équippé est mis en place avec les capuchons 9 dans la partie inférieure a du maillon 1 entre les parties extérieures, le rubis 8 étant pressé dans le demi-logement 4 de cette partie a. La partie supérieure b du maillon est alors disposée sur la partie a et les deux moitiés a et b sont soudées ensemble, par exemple par point. Ensuite, la partie inférieure a du maillon adjacent est disposée avec sa partie centrale 2 sous la partie médiane de l'axe 3, les renflements 7 entrant dans les gorges 6 de celui-ci, puis la partie supérieure b du maillon adjacent est disposée sur la partie a de ce maillon et les deux moitiés a et b sont soudées ensemble. De cette manière, les deux maillons sont articulés l'un à l'autre par un axe solidaire de la partie centrale du second maillon 2 et tournant dans les éléments de grande dureté tels que rubis ou similaires solidaires du premier maillon. Lors de sa mise en place sur la partie inférieure a du premier maillon, l'axe 3 est positionné longitudinalement par les gorges 6 et les renflements 7.Figure 1 shows in 1 the outer parts of a first link of the bracelet articulated with the central part 2 of the adjacent link. As shown in Figure 2, the links are divided into two parts a and b in the direction of the height, these parts being superimposed and welded together by point after the establishment of the axis, in the finished bracelet. The links 1 and 2 are assembled by a hinge comprising an axis 3 disposed between the outer parts 1 of the first link and passing through the central part 2 of the second link. In parts 1, the axis 3 engages with play in a housing 4. In the embodiment illustrated in FIG. 1, the axis ends on each side by a bearing and a pivot 5. The axis comprises in addition in its central part grooves 6 in which are engaged bulges 7 of the central part 2 of the adjacent link. These grooves and bulges prevent the axis from moving axially. The bulges 7 indicated in FIG. 1 are those of the lower part a of the adjacent link 2. On the pivots 5 there is an element of great hardness 8, for example a ruby, forming a bearing for the axis 3, that is to say -to say that the pivot turns freely in the elements 8 which are pressed in the housing 4. A cap 9 with a blind hole comes to shoulder the element 8 and closes the housing 4. During assembly, the elements 8 are first disposed on the pivots 5, then the axis thus equipped is put in place with the caps 9 in the lower part a of the link 1 between the external parts, the ruby 8 being pressed into the half-housing 4 of this part a. The upper part b of the link is then placed on part a and the two halves a and b are welded together, for example by point. Then, the lower part a of the adjacent link is placed with its central part 2 under the middle part of the axis 3, the bulges 7 entering the grooves 6 thereof, then the upper part b of the adjacent link is placed on part a of this link and the two halves a and b are welded together. In this way, the two links are articulated to each other by an axis integral with the central part of the second link 2 and rotating in the elements of great hardness such as rubies or the like, integral with the first link. When it is placed on the lower part a of the first link, the axis 3 is positioned longitudinally by the grooves 6 and the bulges 7.

La figure 3 montre une autre forme d'exécution de l'articulation des maillons 1 et 2 du bracelet selon l'invention. Dans ce cas, l'articulation comporte deux axes 10 se terminant à leur extrémité extérieure par une vis 11 engagée dans un logement fileté 12. Les axes 10 s'étendent jusqu'au milieu de la partie centrale 2 du maillon 2 adjacent au maillon 1. Le rubis ou similaire 8 est pris en sandwich entre une bague de positionnemenmt 13 positionnée elle-même axialement par une gorge 16 et un renflement 14 de la partie centrale 2 du maillon adjacent 2 et une bague de serrage 15. L'axe 10 a un jeu par rapport aux bagues 13 et 15 et il peut tourner dans l'élément 8 qui est solidaire de la partie centrale 2 du maillon 2. Cette disposition permet, en dévissant les axes 10, de sortir ceux-ci, et d'effectuer une mise de longueur du bracelet. Dans la forme d'exécution selon figure 3, les axes 10 ne tournent pas par rapport au premier maillon avec les parties extérieures 1.Figure 3 shows another embodiment of the articulation of the links 1 and 2 of the bracelet according to the invention. In this case, the articulation comprises two axes 10 ending at their outer end by a screw 11 engaged in a threaded housing 12. The axes 10 extend to the middle of the central part 2 of the link 2 adjacent to the link 1 The ruby or the like 8 is sandwiched between a positioning ring 13 itself positioned axially by a groove 16 and a bulge 14 in the central part 2 of the adjacent link 2 and a tightening ring 15. The axis 10 has a clearance with respect to the rings 13 and 15 and it can rotate in the element 8 which is integral with the central part 2 of the link 2. This arrangement makes it possible, by unscrewing the axes 10, to remove these, and to carry out a length adjustment of the bracelet. In the embodiment according to Figure 3, the axes 10 do not rotate relative to the first link with the outer parts 1.

Les figures 4 à 6 montrent des variantes possibles de la disposition des éléments de grande dureté 8 sur l'axe. En figure 4, l'élément est simplement enfilé sur l'axe. En figure 5, l'élément est positionné par une douille 17 logée sur l'axe et la variante de la figure 6 correspond au cas illustré en figure 1.Figures 4 to 6 show possible variants of the arrangement of the elements of high hardness 8 on the axis. In Figure 4, the element is simply threaded on the axis. In FIG. 5, the element is positioned by a socket 17 housed on the axis and the variant of FIG. 6 corresponds to the case illustrated in FIG. 1.

Ce qui précède montre que l'utilisation d'éléments de pivotement de grande dureté, tels que rubis ou similaires et de maillons de bracelet en deux parties dans le sens de la -hauteur, permet de réaliser un bracelet à maillons articulés de relativement faible épaisseur, ne comportant pratiquement aucun risque d'usure et d'apparition de jeu au niveau des articulations et dans lequel les articulations sont extrêmement libres.The above shows that the use of pivoting elements of great hardness, such as rubies or the like and of bracelet links in two parts in the direction of the height, makes it possible to produce a bracelet with articulated links of relatively small thickness. , with virtually no risk of wear and appearance of play at the joints and in which the joints are extremely free.
