  • This fixing device 1 is based first on a particular geometry arranged at the level of the lug of the middle part 2, and which cooperates with a corresponding particular geometry arranged at the end of the strand of bracelet 10.
  • the lug in fact comprises a component whose section has, for example, a U-shaped or substantially U-shaped oriented towards the bracelet, which thus defines a transverse groove.
  • This groove extends transversely from the first horn 3 to the second horn 3 (measured along the transverse axis y) and is delimited by a lower surface 4, an upper surface 5, and a vertical surface 6 connecting these two lower surfaces and superior to the level of the middle part 2.

This construction is designed so that the two bores 7, 17 are substantially aligned when the projection 16 of the bracelet 10 is housed in the groove of the lug.
  • the bracelet 10 further comprises a housing 18 at the lower surface of the projection 16, intended to receive an elastic element 30, in a removable manner.
  • Such an elastic element 30 thus extends substantially in a plane parallel to the plane of the bracelet strand, and comprises a through opening which can be offset, in particular offset by a magnitude preferably between 0.02 mm and 0.5 mm with the bore 17 of the projection, as will be detailed later.
  • the fixing device 1 of the bracelet strand 10 on the watch case further comprises a pin 20, a lower portion 23 of which is housed in the bore 7 of the middle part 2, an intermediate portion 22 is housed in the bore of the elastic element 30, and an upper portion 21 is housed in the bore 17 of the projection 16 of the bracelet 10.

  • the elastic element 30 comprises a substantially annular shape
  • the housing 18 has a circular section whose diameter may be slightly less than the diameter of the elastic element, so as to allow the element to be maintained elastic in said housing by its slight compression.
  • the end of the bracelet is positioned in the lug of the watch case, so that the projection 16 of the bracelet is positioned in the groove arranged at the lug.
  • the height of this projection 16 corresponds substantially to the distance between the two lower surfaces 4 and upper 5 delimiting the groove in height, with a slight play to facilitate the insertion of the projection without resistance.
  • the depth of the groove corresponds substantially to the length of the projection 16, measured in the longitudinal direction, with a slight clearance to ensure that this projection is not blocked by an inadvertent stop of its vertical surface 12 at its end.
  • the pin 20 is inserted through the bore 7 of the middle part 2.
  • the upper portion 21 of the pin has a diameter greater than that of its intermediate section 22.
  • This upper portion 21 of the pin also has a diameter greater than that of the bore of the elastic element 30.
  • the pin 20 is thus driven through the elastic element: naturally, the aforementioned diameters and the elastic property of the elastic element are chosen to allow insertion of the pin, with adequate force and without deterioration of the elastic element, but guaranteeing good retention of the pin and the bracelet at the end of this insertion.
  • This insertion continues until the pin 20 reaches its final position, represented by the figure 2 And 5 , in which its intermediate portion 22 of smaller diameter of the pin 20 is positioned within the bore of the elastic element 30.
  • the elastic element 30 makes it possible to form a reliable and stable connection of the pin. This results in reliable fixation of the bracelet.
  • the elastic element 30, through its elastic property, takes up any play and allows for play-free attachment of the bracelet 10 to the watch case.
  • the insertion of the pin 20 has the effect of pressing the upper surface 15 of the projection 16 against the upper surface 5 of the groove, thus ensuring locking without play in the vertical direction of the bracelet.
  • an offset is provided between the housing 18 and the bore 17 of the bracelet 10.
  • An offset is also provided between the housing 18 of the bracelet and the bore 7 of the watch case. More precisely, the axis A 17 of the bore 17 of the bracelet 10 is arranged slightly set back in the longitudinal direction relative to the axis of the housing 18 of the watch case, which defines the axis A 30 of the elastic element 30. Thus, the through opening of the elastic element 30 is slightly offset with the bore 17 of the bracelet 10, as is more particularly shown in the Figure 3 .
  • the positioning of the pin 20 through the two bores 7 and 17 is possible by the deformation, in particular the compression, of the elastic element 30 which compensates for the aforementioned misalignment.
  • This achievement promotes holding the bracelet without play in the longitudinal direction. It also ensures continuity between the upper surfaces of the watch case and the upper surface of the bracelet, at their interface, which guarantees a good aesthetic perception.
  • THE figures 6 and 7 illustrate a phase of detachment from a bracelet.
  • the pin 20 is driven through the elastic element, in the same direction as in the joining phase described previously.

Pour faciliter la description qui va suivre, nous désignerons par direction verticale z la direction perpendiculaire au plan de la boîte de montre, orientée vers un observateur de la montre. L'adjectif « inférieur » désignera donc le côté de la boîte de montre et du bracelet destiné à venir en contact avec le poignet d'un porteur. Nous désignerons par direction transversale y la direction s'étendant du centre d'une première corne 3 au centre d'une deuxième corne 3 en vis-à-vis, perpendiculairement à la direction verticale. Enfin, nous désignerons par direction longitudinale x la direction orientée selon la longueur du bracelet, perpendiculairement aux directions verticale et latérale.To facilitate the description which follows, we will designate by vertical direction z the direction perpendicular to the plane of the watch case, oriented towards an observer of the watch. The adjective “lower” will therefore designate the side of the watch case and the bracelet intended to come into contact with the wrist of a wearer. We will designate by transverse direction y the direction extending from the center of a first horn 3 to the center of a second horn 3 facing each other, perpendicular to the vertical direction. Finally, we will designate by longitudinal direction x the direction oriented according to the length of the bracelet, perpendicular to the vertical and lateral directions.

La figure 1 représente une boite de montre dont la carrure 2 comprend sur sa périphérie deux ensembles de deux cornes 3 symétriquement et diamétralement opposés, entre lesquels peuvent être fixés deux brins de bracelet 10 de manière amovible par un dispositif de fixation 1 selon un mode de réalisation de l'invention. Par simplification, cette figure 1 représente l'extrémité d'un seul brin de bracelet, plus exactement un maillon d'extrémité d'un bracelet, un tel bracelet pouvant être destiné à être composé de maillons assemblés. Ce maillon d'extrémité comprend une première extrémité correspondant à l'extrémité du bracelet, fixée à la boîte de montre, et une deuxième extrémité comprenant un dispositif de réception 11 pour un autre maillon du brin de bracelet, sous la forme d'une ouverture transversale prévue pour recevoir un axe de liaison. Naturellement, le dispositif de fixation 1 selon le mode de réalisation de l'invention est adapté pour la fixation de tout autre type de bracelet ou de brin de bracelet qu'un bracelet à maillons articulés, comme un brin de bracelet souple, par exemple en cuir ou en matériau composite. D'autre part, deux brins de bracelet seront de préférence respectivement fixés entre respectivement chaque ensemble de deux cornes 3 de la carrure 2 de boîte de montre par un même dispositif de fixation 1, puis fixés entre eux sur leur autre extrémité par un fermoir.There figure 1 represents a watch case whose middle part 2 comprises on its periphery two sets of two horns 3 symmetrically and diametrically opposed, between which two strands of bracelet 10 can be fixed in a removable manner by a fixing device 1 according to one embodiment of the 'invention. For simplification, this figure 1 represents the end of a single strand of bracelet, more precisely an end link of a bracelet, such a bracelet may be intended to be composed of assembled links. This end link comprises a first end corresponding to the end of the bracelet, fixed to the watch case, and a second end comprising a receiving device 11 for another link of the bracelet strand, in the form of an opening transversal intended to receive a connecting axis. Naturally, the fixing device 1 according to the embodiment of the invention is suitable for fixing any other type of bracelet or bracelet strand than a bracelet with articulated links, such as a flexible bracelet strand, for example in leather or composite material. On the other hand, two bracelet strands will preferably be respectively fixed between each set of two horns 3 of the middle part 2 of the watch case by the same fixing device 1, then fixed together on their other end by a clasp.

Le dispositif de fixation 1 d'un brin de bracelet 10 selon le mode de réalisation de l'invention est plus précisément représenté par la figure 2, en configuration de fixation du bracelet 10. Ce dispositif de fixation 1 repose d'abord sur une géométrie particulière agencée au niveau de l'entrecorne de la carrure 2, et qui coopère avec une géométrie particulière correspondante agencée à l'extrémité du brin de bracelet 10.The fixing device 1 of a bracelet strand 10 according to the embodiment of the invention is more precisely represented by the figure 2 , in the configuration for fixing the bracelet 10. This fixing device 1 is based first on a particular geometry arranged at the level of the lug of the middle part 2, and which cooperates with a corresponding particular geometry arranged at the end of the strand of bracelet 10.

L'entrecorne comprend en effet un composant dont la section présente, par exemple, une forme en U ou sensiblement en U orientée vers le bracelet, qui définit ainsi une rainure transversale. Cette rainure s'étend transversalement de la première corne 3 à la deuxième corne 3 (mesurée selon l'axe transversal y) et est délimité par une surface inférieure 4, une surface supérieure 5, et une surface verticale 6 reliant ces deux surfaces inférieure et supérieure au niveau de la carrure 2. La surface inférieure 4 comprend un alésage 7 (ou ouverture 7) traversant, orienté verticalement, positionné sensiblement au centre de l'entrecorne en considérant la direction transversale.The lug in fact comprises a component whose section has, for example, a U-shaped or substantially U-shaped oriented towards the bracelet, which thus defines a transverse groove. This groove extends transversely from the first horn 3 to the second horn 3 (measured along the transverse axis y) and is delimited by a lower surface 4, an upper surface 5, and a vertical surface 6 connecting these two lower surfaces and superior to the level of the middle part 2. The lower surface 4 comprises a through bore 7 (or opening 7), oriented vertically, positioned substantially in the center of the lug considering the transverse direction.

Le bracelet 10 comprend une saillie 16 à son extrémité, plus précisément représentée par la figure 3, destinée à un logement au sein de la rainure agencée dans l'entrecorne de la carrure. Cette saillie 16 comprend un alésage 17 (ou ouverture 17) traversant, orienté verticalement, positionné sensiblement au centre de la saillie en considérant la direction transversale. Cette construction est prévue pour que les deux alésages 7, 17 soient sensiblement alignés lorsque la saillie 16 du bracelet 10 est logée dans la rainure de l'entrecorne. Le bracelet 10 comprend de plus un logement 18 au niveau de la surface inférieure de la saillie 16, prévu pour recevoir un élément élastique 30, de manière amovible. Un tel élément élastique 30 s'étend ainsi sensiblement dans un plan parallèle au plan du brin de bracelet, et comprend une ouverture traversante qui peut être désaxée, notamment désaxée d'une grandeur préférentiellement comprise entre 0.02 mm et 0.5 mm avec l'alésage 17 de la saillie, comme cela sera détaillé par la suite.The bracelet 10 includes a projection 16 at its end, more precisely represented by the Figure 3 , intended for housing within the groove arranged in the lug of the middle part. This projection 16 comprises a through bore 17 (or opening 17), oriented vertically, positioned substantially in the center of the projection considering the transverse direction. This construction is designed so that the two bores 7, 17 are substantially aligned when the projection 16 of the bracelet 10 is housed in the groove of the lug. The bracelet 10 further comprises a housing 18 at the lower surface of the projection 16, intended to receive an elastic element 30, in a removable manner. Such an elastic element 30 thus extends substantially in a plane parallel to the plane of the bracelet strand, and comprises a through opening which can be offset, in particular offset by a magnitude preferably between 0.02 mm and 0.5 mm with the bore 17 of the projection, as will be detailed later.

Le dispositif de fixation 1 du brin de bracelet 10 sur la boîte de montre comprend de plus une goupille 20, dont une portion inférieure 23 est logée dans l'alésage 7 de la carrure 2, une portion intermédiaire 22 est logée dans l'alésage de l'élément élastique 30, et une portion supérieure 21 est logée dans l'alésage 17 de la saillie 16 du bracelet 10. Cette goupille 20, en coopération avec l'élément élastique 30, assure ainsi le maintien fiable et sans jeu du bracelet 10 sur la boîte de montre.The fixing device 1 of the bracelet strand 10 on the watch case further comprises a pin 20, a lower portion 23 of which is housed in the bore 7 of the middle part 2, an intermediate portion 22 is housed in the bore of the elastic element 30, and an upper portion 21 is housed in the bore 17 of the projection 16 of the bracelet 10. This pin 20, in cooperation with the elastic element 30, thus ensures the reliable and play-free maintenance of the bracelet 10 on the watch case.

Le fonctionnement du dispositif de fixation de bracelet selon le mode de réalisation va maintenant être détaillé, en référence aux figures 4 et 5.The operation of the bracelet fixing device according to the embodiment will now be detailed, with reference to the figures 4 and 5 .

En phase préalable, un élément élastique 30 est positionné dans le logement 18 prévu à l'extrémité du bracelet, mentionné précédemment. Selon le mode de réalisation, l'élément élastique 30 comprend une forme sensiblement annulaire, et le logement 18 présente une section circulaire dont le diamètre peut être légèrement inférieur au diamètre de l'élément élastique, de sorte à permettre le maintien de l'élément élastique dans ledit logement par sa légère compression. Ensuite, l'extrémité du bracelet est positionnée dans l'entrecorne de la boîte de montre, de sorte que la saillie 16 du bracelet vienne se positionner dans la rainure agencée à l'entrecorne. En remarque, la hauteur de cette saillie 16 correspond sensiblement à la distance entre les deux surfaces inférieure 4 et supérieure 5 délimitant la rainure en hauteur, avec un léger jeu pour faciliter l'insertion de la saillie sans résistance. De même, la profondeur de la rainure correspond sensiblement à la longueur de la saillie 16, mesurée selon la direction longitudinale, avec un léger jeu pour assurer que cette saillie ne soit pas bloquée par une butée intempestive de sa surface verticale 12 à son extrémité.In the preliminary phase, an elastic element 30 is positioned in the housing 18 provided at the end of the bracelet, mentioned previously. According to the embodiment, the elastic element 30 comprises a substantially annular shape, and the housing 18 has a circular section whose diameter may be slightly less than the diameter of the elastic element, so as to allow the element to be maintained elastic in said housing by its slight compression. Then, the end of the bracelet is positioned in the lug of the watch case, so that the projection 16 of the bracelet is positioned in the groove arranged at the lug. As a note, the height of this projection 16 corresponds substantially to the distance between the two lower surfaces 4 and upper 5 delimiting the groove in height, with a slight play to facilitate the insertion of the projection without resistance. Likewise, the depth of the groove corresponds substantially to the length of the projection 16, measured in the longitudinal direction, with a slight clearance to ensure that this projection is not blocked by an inadvertent stop of its vertical surface 12 at its end.

Ensuite, comme représenté par la figure 4 qui montre une phase transitoire d'insertion verticale de la goupille, la goupille 20 est insérée par l'alésage 7 de la carrure 2. La portion supérieure 21 de la goupille présente un diamètre supérieur à celui de sa section intermédiaire 22. Cette portion supérieure 21 de la goupille présente de même un diamètre supérieur à celui de l'alésage de l'élément élastique 30. La goupille 20 est ainsi chassée au travers de l'élément élastique : naturellement, les diamètres susmentionnés et la propriété élastique de l'élément élastique sont choisis pour autoriser une insertion de la goupille, avec une force adéquate et sans détérioration de l'élément élastique, mais garantissant un bon maintien de la goupille et du bracelet à la fin de cette insertion. Cette insertion se poursuit jusqu'à ce que la goupille 20 atteigne sa position finale, représentée par les figures 2 et 5, dans laquelle sa portion intermédiaire 22 de plus petit diamètre de la goupille 20 est positionnée au sein de l'alésage de l'élément élastique 30.Then, as represented by the Figure 4 which shows a transient phase of vertical insertion of the pin, the pin 20 is inserted through the bore 7 of the middle part 2. The upper portion 21 of the pin has a diameter greater than that of its intermediate section 22. This upper portion 21 of the pin also has a diameter greater than that of the bore of the elastic element 30. The pin 20 is thus driven through the elastic element: naturally, the aforementioned diameters and the elastic property of the elastic element are chosen to allow insertion of the pin, with adequate force and without deterioration of the elastic element, but guaranteeing good retention of the pin and the bracelet at the end of this insertion. This insertion continues until the pin 20 reaches its final position, represented by the figure 2 And 5 , in which its intermediate portion 22 of smaller diameter of the pin 20 is positioned within the bore of the elastic element 30.

Dans la position finale de la goupille 20, il apparaît qu'elle est bloquée axialement par l'élément élastique 30, ce qui permet de former une liaison fiable et stable de la goupille. Il en ressort une fixation fiable du bracelet. D'autre part, l'élément élastique 30, par sa propriété élastique, rattrape les éventuels jeux et permet une fixation sans jeu du bracelet 10 sur la boîte de montre. L'insertion de la goupille 20 a pour effet de plaquer la surface supérieure 15 de la saillie 16 contre la surface supérieure 5 de la rainure, assurant ainsi un blocage sans jeu dans la direction verticale du bracelet.In the final position of the pin 20, it appears that it is blocked axially by the elastic element 30, which makes it possible to form a reliable and stable connection of the pin. This results in reliable fixation of the bracelet. On the other hand, the elastic element 30, through its elastic property, takes up any play and allows for play-free attachment of the bracelet 10 to the watch case. The insertion of the pin 20 has the effect of pressing the upper surface 15 of the projection 16 against the upper surface 5 of the groove, thus ensuring locking without play in the vertical direction of the bracelet.

Selon le mode de réalisation de l'invention, un désaxage est prévu entre le logement 18 et l'alésage 17 du bracelet 10. Un désaxage est également prévu entre le logement 18 du bracelet et l'alésage 7 de la boîte de montre. Plus précisément, l'axe A17 de l'alésage 17 du bracelet 10 est agencé légèrement en retrait dans la direction longitudinale par rapport à l'axe du logement 18 de la boîte de montre, qui définit l'axe A30 de l'élément élastique 30. Ainsi, l'ouverture traversante de l'élément élastique 30 est légèrement désaxée avec l'alésage 17 du bracelet 10, comme cela est plus particulièrement représenté sur la figure 3.According to the embodiment of the invention, an offset is provided between the housing 18 and the bore 17 of the bracelet 10. An offset is also provided between the housing 18 of the bracelet and the bore 7 of the watch case. More precisely, the axis A 17 of the bore 17 of the bracelet 10 is arranged slightly set back in the longitudinal direction relative to the axis of the housing 18 of the watch case, which defines the axis A 30 of the elastic element 30. Thus, the through opening of the elastic element 30 is slightly offset with the bore 17 of the bracelet 10, as is more particularly shown in the Figure 3 .

Le positionnement de la goupille 20 au travers des deux alésages 7 et 17 est possible par la déformation, notamment la compression, de l'élément élastique 30 qui compense le désaxage susmentionné. Il en résulte un effort particulier exercé sur le bracelet, orienté dans la direction longitudinale vers la boîte de montre, qui tend à plaquer une surface supérieure verticale 19 du bracelet à l'encontre d'une surface verticale 8 à l'extrémité de la surface supérieure 5 de la rainure à l'entrecorne. Cette réalisation favorise le maintien sans jeu du bracelet dans la direction longitudinale. Elle permet de plus d'assurer la continuité entre les surfaces supérieures de la boîte de montre et la surface supérieure du bracelet, au niveau de leur interface, ce qui garantit une bonne perception esthétique.The positioning of the pin 20 through the two bores 7 and 17 is possible by the deformation, in particular the compression, of the elastic element 30 which compensates for the aforementioned misalignment. This results in an effort particular exercised on the bracelet, oriented in the longitudinal direction towards the watch case, which tends to press a vertical upper surface 19 of the bracelet against a vertical surface 8 at the end of the upper surface 5 of the groove at the crotch. This achievement promotes holding the bracelet without play in the longitudinal direction. It also ensures continuity between the upper surfaces of the watch case and the upper surface of the bracelet, at their interface, which guarantees a good aesthetic perception.

Les figures 6 et 7 illustrent une phase de désolidarisation d'un bracelet. Pour cela, la goupille 20 est chassée au travers de l'élément élastique, dans la même direction que dans la phase de solidarisation décrite précédemment. Dans cette opération, la portion inférieure 23 de la goupille, de diamètre sensiblement égal à celui de la portion supérieure 21, vient se loger au sein de l'élément élastique 30. L'opération est poursuivie jusqu'à ce que la goupille 20 sorte totalement de l'alésage 7 à l'entrecorne de la carrure, dans la position représentée sur les figures 6 et 7. En remarque, pour permettre cette opération, la longueur L10 de l'alésage 17 du bracelet 10 est au moins égale à la longueur L20 de la goupille 20. Ainsi, l'alésage 17 pourrait en variante être un alésage borgne, tant qu'il respecte la condition précédente. Dans la position des figures 6 et 7, il apparaît que la goupille ne bloque plus le bracelet 10 qui peut être retiré par une simple traction dans la direction longitudinale x. La goupille 20 peut alors être récupérée ou remplacée pour une prochaine opération de solidarisation.THE figures 6 and 7 illustrate a phase of detachment from a bracelet. To do this, the pin 20 is driven through the elastic element, in the same direction as in the joining phase described previously. In this operation, the lower portion 23 of the pin, of diameter substantially equal to that of the upper portion 21, is housed within the elastic element 30. The operation is continued until the pin 20 comes out completely from bore 7 to the lug of the middle, in the position shown on the figures 6 and 7 . As a note, to allow this operation, the length L10 of the bore 17 of the bracelet 10 is at least equal to the length L20 of the pin 20. Thus, the bore 17 could alternatively be a blind bore, as long as it respects the previous condition. In the position of figures 6 and 7 , it appears that the pin no longer blocks the bracelet 10 which can be removed by simple traction in the longitudinal direction x. The pin 20 can then be recovered or replaced for a future joining operation.

L'élément élastique 30 se présente comme une bague ou un anneau élastique. Il peut être un joint polymère ou un joint élastomère. Sa section peut présenter une forme en « U », comme représenté particulièrement par la figure 8 et les figures 2 à 7, ou une forme en « T », comme représenté par la figure 9. En variante, l'élément élastique 30 peut être un joint torique, comme représenté par la figure 10, ou encore un joint quadrilobe, comme représenté par la figure 11. Selon encore une autre variante, il est également envisageable d'utiliser une rondelle ressort, notamment un clinquant, comme représenté par la figure 12. D'autre part, l'élément élastique peut prendre en variante toute autre forme.The elastic element 30 appears as a ring or an elastic ring. It can be a polymer seal or an elastomer seal. Its section can have a “U” shape, as particularly represented by the figure 8 and the figures 2 to 7 , or a “T” shape, as represented by the Figure 9 . Alternatively, the elastic element 30 can be an O-ring, as represented by the Figure 10 , or even a quatrefoil joint, like represented by the Figure 11 . According to yet another variant, it is also possible to use a spring washer, in particular a foil, as represented by the Figure 12 . On the other hand, the elastic element can alternatively take any other shape.

Naturellement, l'invention ne se limite pas au mode de réalisation décrit. Ainsi, la carrure, voire la boîte de montre, pourrait comprendre toute autre forme permettant la réception d'un bracelet et le maintien par une goupille verticale. Par exemple, l'alésage 7 de la carrure pourrait en variante être un alésage de la surface supérieure 5 de la rainure et le bracelet comprendrait un élément élastique agencé au niveau de sa surface supérieure. La carrure ne comprend pas nécessairement des cornes, une rainure pouvant être agencée de manière indépendante des cornes. De plus, le bracelet pourrait comprendre une saillie de géométrie différente. L'alésage 17 du bracelet peut être débouchant sur l'une ou l'autre des faces de la saillie du brin de bracelet, sans être nécessairement traversant. L'élément élastique pourrait être agencé différemment en correspondance avec l'alésage du bracelet.Naturally, the invention is not limited to the embodiment described. Thus, the middle part, or even the watch case, could include any other shape allowing the reception of a bracelet and the maintenance by a vertical pin. For example, the bore 7 of the middle part could alternatively be a bore of the upper surface 5 of the groove and the bracelet would comprise an elastic element arranged at the level of its upper surface. The middle part does not necessarily include horns, a groove being able to be arranged independently of the horns. In addition, the bracelet could include a projection of different geometry. The bore 17 of the bracelet can open onto one or other of the faces of the projection of the bracelet strand, without necessarily passing through. The elastic element could be arranged differently in correspondence with the bore of the bracelet.

Par ailleurs, la goupille peut présenter un diamètre maximal inférieur ou égal à 1,5 mm. Ce diamètre est de préférence compris entre 0,8 et 1,4 mm inclus. La goupille peut en variante présenter une autre géométrie, par exemple une section de forme non circulaire. En variante, elle peut présenter une géométrie simplifiée, avec une section constante sur toute sa longueur, prévue pour permettre les opérations de solidarisation et désolidarisation au travers l'élément élastique tout en garantissant un bon maintien de l'ensemble. Enfin, le mode de réalisation permet d'atteindre un résultat satisfaisant avec une unique goupille. En variante, deux goupilles ou plus pourraient être utilisées pour la fixation d'un même brin de bracelet.Furthermore, the pin may have a maximum diameter less than or equal to 1.5 mm. This diameter is preferably between 0.8 and 1.4 mm inclusive. The pin may alternatively have another geometry, for example a section of non-circular shape. Alternatively, it can have a simplified geometry, with a constant section over its entire length, designed to allow joining and uncoupling operations through the elastic element while guaranteeing good maintenance of the assembly. Finally, the embodiment makes it possible to achieve a satisfactory result with a single pin. Alternatively, two or more pins could be used to secure the same bracelet strand.

Enfin, la connexion décrite précédemment peut naturellement être inversée, la saillie étant agencée au niveau de la carrure, notamment d'une entrecorne, de sorte à coopérer avec une rainure agencée à l'extrémité d'un brin de bracelet. D'autre part, dans les deux cas, l'élément élastique est logé dans le bracelet.Finally, the connection described above can naturally be reversed, the projection being arranged at the level of the middle part, in particular of a lug, so as to cooperate with a groove arranged at the end of a bracelet strand. On the other hand, in both cases, the elastic element is housed in the bracelet.
