Description

La présente invention concerne un bracelet articulé, notamment pour montre. Elle concerne plus particulièrement un bracelet formé d'une suite de barrettes disposées parallèlement les unes aux autres et maintenues en place à l'aide d'éléments de liaison pouvant pivoter autour des axes des barrettes.The present invention relates to an articulated bracelet, in particular for a watch. It relates more particularly to a bracelet formed of a series of bars arranged parallel to each other and held in place by means of connecting elements which can pivot around the axes of the bars.

De tels bracelets sont bien connus et il existe une grande variété de dispositifs de liaison entre barrettes.Such bracelets are well known and there are a wide variety of connecting devices between bars.

Un exemple d'un tel bracelet est décrit en détail dans le brevet CH 647.661. Dans cette réalisation, les barrettes sont des tiges cylindriques ayant une longueur qui augmente à mesure qu'elles se rapprochent de l'extrémité du bracelet destinée à être fixée à une boîte de montre. Les éléments de liaison, reliant deux barrettes adjacentes, sont formés chacun de deux anneaux soudés ensemble en un point de leur périphérie. Le maintien latéral des éléments de liaison sur les barrettes est obtenu en soudant un des anneaux de chaque élément sur la barrette qui le traverse. Sur les extrémités des barrettes sont encore soudées des têtes contre lesquelles viennent s'appuyer les anneaux des éléments de liaison afin de permettre au bracelet de mieux résister à des efforts transversaux.An example of such a bracelet is described in detail in patent CH 647,661. In this embodiment, the bars are cylindrical rods having a length which increases as they approach the end of the strap intended to be fixed to a watch case. The connecting elements, connecting two adjacent bars, are each formed of two rings welded together at a point on their periphery. The lateral retention of the connecting elements on the bars is obtained by welding one of the rings of each element on the bar which passes through it. On the ends of the bars are still welded heads against which the rings of the connecting elements come to bear in order to allow the bracelet to better resist transverse forces.

Les solutions adoptées pour la réalisation de ce bracelet présentent cependant plusieurs inconvénients. En effet, d'une part, ce bracelet nécessite beau coup de composants différents, lesquels sont assemblés par des opérations de soudage délicates, entraînant un prix de fabrication élevé. D'autre part, il est difficile à démonter, opération pourtant indispensable pour mettre le bracelet de longueur ou remplacer une partie défectueuse par exemple.The solutions adopted for the production of this bracelet, however, have several drawbacks. Indeed, on the one hand, this bracelet requires a lot of different components, which are assembled by delicate welding operations, resulting in a high manufacturing price. On the other hand, it is difficult to dismantle, an operation which is nevertheless essential for putting on the length bracelet or replacing a defective part, for example.

La présente invention se propose de pallier ces inconvénients en réalisant un bracelet articulé simple, bon marché, utilisant peu de pièces différentes et pouvant être monté et démonté facilement sans outillage spécial.The present invention proposes to overcome these drawbacks by making a simple, inexpensive articulated bracelet, using few different parts and which can be easily assembled and disassembled without special tools.

Pour atteindre cet objectif, le bracelet selon l'invention, comprenant des barrettes disposées parallèlement les unes aux autres et perpendiculairement à l'axe longitudinal du bracelet, et des éléments de liaison destinés à relier une barrette à une barrette adjacente, tout en restant libres de pivoter autour des axes des barrettes, est particulièrement remarquable en ce que chacun des éléments de liaison est formé de deux crochets sensiblement plans, et d'un pont reliant les deux crochets ensemble, chaque crochet, qui constitue une des deux extrémités de cet élément, est pourvu d'un trou transversal, d'axe perpendiculaire au plan du crochet, ce trou débouchant vers l'extérieur par une fente latérale, disposée perpendiculairement à la droite joignant les centres des trous, la largeur de la fente étant inférieure au diamètre du trou de manière que chaque extrémité de l'élément de liaison puisse être engagé à force, par déformation élastique du crochet correspondant, dans une gorge de révolution pratiquée dans chaque barrette, le diamètre de la gorge étant égal au diamètre du trou du crochet.To achieve this objective, the bracelet according to the invention, comprising bars arranged parallel to each other and perpendicular to the longitudinal axis of the bracelet, and connecting elements intended to connect a bar to an adjacent bar, while remaining free to pivot around the axes of the bars, is particularly remarkable in that each of the connecting elements is formed of two substantially planar hooks, and of a bridge connecting the two hooks together, each hook, which constitutes one of the two ends of this element , is provided with a transverse hole, with an axis perpendicular to the plane of the hook, this hole opening towards the outside by a lateral slot, arranged perpendicular to the right joining the centers of the holes, the width of the slot being less than the diameter of the hole so that each end of the connecting element can be forcibly engaged, by elastic deformation of the corresponding hook, in a groove of re evolution practiced in each bar, the diameter of the groove being equal to the diameter of the hole of the hook.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description qui va suivre, faite en regard du dessin annexé et donnant, à titre d'exemple explicatif mais nullement limitatif, une forme avantageuse de réalisation d'un bracelet articulé. Sur ce dessin, où les mêmes références se rapportent à des éléments analogues :

  • - la fig. 1 est une vue en perspective d'une partie du bracelet selon l'invention montrant, en a), deux barrettes adjacentes et, en b), un élément de liaison, coupé en deux parties pour faciliter la lecture du dessin;
  • - la fig. 2 est une vue en plan du côté extérieur d'une partie du bracelet, côté qui n'est pas destiné à venir en contact avec le poignet du porteur de la montre; et
  • - la fig. 3 montre, dans une vue partielle en perspective, une exécution particulière de l'élément de liaison.
Other characteristics and advantages of the present invention will emerge from the description which follows, given with reference to the appended drawing and giving, by way of explanatory but in no way limiting example, an advantageous embodiment of an articulated bracelet. In this drawing, where the same references relate to similar elements:
  • - fig. 1 is a perspective view of a part of the bracelet according to the invention showing, in a), two adjacent bars and, in b), a connecting element, cut into two parts to facilitate reading of the drawing;
  • - fig. 2 is a plan view of the outside of a part of the bracelet, a side which is not intended to come into contact with the wrist of the wearer of the watch; and
  • - fig. 3 shows, in a partial perspective view, a particular embodiment of the connecting element.

En référence au dessin, la fig. 1a) montre deux barrettes adjacentes, référencées 1 et 2, d'une forme d'exécution du bracelet selon l'invention. Pour rendre le dessin plus clair la distance séparant les deux barrettes a été intentionnellement augmentée. Les barrettes dans cette réalisation sont cylindriques et leur surface est lisse, mais des formes différentes, tout en restant sensiblement cylindriques, pourraient aussi convenir, de même que la surface pourrait porter des motifs décoratifs, comme par exemple des facettes.With reference to the drawing, fig. 1a) shows two adjacent bars, referenced 1 and 2, of an embodiment of the bracelet according to the invention. To make the drawing clearer, the distance between the two bars has been intentionally increased. The bars in this embodiment are cylindrical and their surface is smooth, but different shapes, while remaining substantially cylindrical, could also be suitable, just as the surface could carry decorative patterns, such as facets.

Chaque barrette porte deux gorges de même forme 3 et 4, situées à égale distance de ses extrémités. Le fond de chaque gorge est cylindrique et les faces latérales sont planes.Each bar carries two grooves of the same shape 3 and 4, located equidistant from its ends. The bottom of each groove is cylindrical and the lateral faces are flat.

La fig. 1b) montre un élément de liaison 5, coupé par le milieu. Cet élément comprend un premier crochet 6, un second crochet 7, dessinés respectivement au-dessus des barrettes 1 et 2, et un pont 8 reliant un crochet à l'autre. L'élément de liaison est délimité par deux faces planes principales, parallèles entre elles et à un axe joignant les milieux des deux crochets, la distance entre les faces principales définissant l'épaisseur de l'élément. Chaque crochet est délimité extérieurement, de son côté, par une face cylindrique, perpendiculaire aux faces principales, dont le diamètre est sensiblement égal au diamètre des barrettes. Le pont 8 a une section rectangulaire, une des dimensions correspondant à l'épaisseur de l'élément 5 alors que l'autre dimension doit être au plus égale au diamètre d'une barrette. La longueur du pont, qui détermine la distance entre les barrettes du bracelet, n'est choisie qu'en fonction de critères esthétiques.Fig. 1b) shows a connecting element 5, cut through the middle. This element comprises a first hook 6, a second hook 7, drawn respectively above the bars 1 and 2, and a bridge 8 connecting one hook to the other. The connecting element is delimited by two main plane faces, parallel to each other and to an axis joining the midpoints of the two hooks, the distance between the main faces defining the thickness of the element. Each hook is delimited externally, for its part, by a cylindrical face, perpendicular to the main faces, the diameter of which is substantially equal to the diameter of the bars. The bridge 8 has a rectangular section, one of the dimensions corresponding to the thickness of the element 5 while the other dimension must be at most equal to the diameter of a bar. The length of the bridge, which determines the distance between the bars of the bracelet, is only chosen according to aesthetic criteria.

Un trou transversal 9, d'axe perpendiculaire aux faces principales, traverse le crochet 6, et un trou similaire 10 traverse le crochet 7. Le diamètre de ces trous est égal au diamètre de la partie cylindrique des gorges 3 et 4. Une fente latérale radiale 11, pratiquée dans le crochet 6, relie le trou 9 avec l'extérieur. La fente est délimitée par deux faces planes parallèles entre elles et perpendiculaires aux faces principales ainsi qu'à l'axe joignant les centres des trous 9 et 10. La distance séparant ces faces détermine la largeur de la fente 11 dont l'axe de symétrie passe par le centre du trou 9. Une fente 12, semblable à la fente précédente, est pratiquée de même dans le crochet 7.A transverse hole 9, with an axis perpendicular to the main faces, passes through the hook 6, and a similar hole 10 passes through the hook 7. The diameter of these holes is equal to the diameter of the cylindrical part of the grooves 3 and 4. A lateral slot radial 11, made in the hook 6, connects the hole 9 with the outside. The slot is delimited by two plane faces parallel to each other and perpendicular to the main faces as well as to the axis joining the centers of the holes 9 and 10. The distance separating these faces determines the width of the slot 11 whose axis of symmetry passes through the center of the hole 9. A slot 12, similar to the preceding slot, is made in the same way in the hook 7.

La largeur des fentes 11 et 12 est choisie légèrement inférieure au diamètre des gorges 3 et 4. De cette façon, ainsi que cela apparaît clairement sur les fig. 1, l'élément de liaison 5 peut être fixé sur les barrettes en introduisant à force le crochet 6 dans la gorge 3 de la barrette 1 et le crochet 7 dans la gorge 3 de la barrette 2. La force exercée par les gorges sur les faces des fentes déforme alors élastiquement les crochets en les ouvrant. Ceci permet aux gorges 3, en pénétrant jusqu'au fond des crochets 6 et 7, de prendre place respectivement dans les trous 9 et 10. Comme les diamètres des trous et des gorges sont égaux, les crochets peuvent reprendre leur forme initiale, emprisonnant les gorges dans cette position qui laisse aux barrettes la possibilité de pivoter autour de leur axe. Bien entendu, en exerçant sur l'élément de liaison une force inverse, il est possible de sortir les crochets des gorges. Ceci montre que l'assemblage des diverses parties du bracelet selon l'invention, ainsi que la séparation de ces parties, peut être fait de façon très simple et économique, sans recourir à un outillage spécial.The width of the slots 11 and 12 is chosen to be slightly less than the diameter of the grooves 3 and 4. In this way, as is clearly seen in FIGS. 1, the connecting element 5 can be fixed on the bars by forcing the hook 6 into the groove 3 of the bar 1 and the hook 7 into the groove 3 of the bar 2. The force exerted by the grooves on the faces of the slots then elastically deforms the hooks by opening them. This allows the grooves 3, penetrating to the bottom of the hooks 6 and 7, to take place respectively in the holes 9 and 10. As the diameters of the holes and the grooves are equal, the hooks can return to their original shape, trapping the grooves in this position which leaves the bars the possibility of pivoting about their axis. Of course, by exerting a reverse force on the connecting element, it is possible to remove the hooks from the grooves. This shows that the assembly of the various parts of the bracelet according to the invention, as well as the separation of these parts, can be done in a very simple and economical manner, without resorting to special tools.

La barrette et l'élément de liaison qui viennent d'être décrits peuvent être obtenus respectivement par décolletage et étampage, c'est-à-dire par des opérations courantes et peu coûteuses, se prêtant bien à une fabrication de grande série. Avec ces deux pièces seulement, il est possible de réali ser un bracelet avantageux, dont une forme de réalisation est représentée sur la fig. 2.The bar and the connecting element which have just been described can be obtained respectively by bar turning and stamping, that is to say by current and inexpensive operations, which are well suited to mass production. With these two parts only, it is possible to make an advantageous bracelet, an embodiment of which is shown in FIG. 2.

Dans ce bracelet la largeur des gorges 3 et 4 est égale au double de l'épaisseur d'un élément de liaison, permettant de placer deux crochets dans la même gorge. De cette façon, un nombre arbitraire de barrettes peuvent être liées ensemble en disposant les éléments de liaison 5 alternativement du côté du bord des barrettes, ou du côté de leur milieu, dans la série des gorges 3 et dans la série des gorges 4. Les éléments de liaison 5 d'une série de gorges sont donc disposés les uns à la suite des autres pour former une rangée. Dans l'exemple du bracelet de la fig. 2 il y a deux rangées, 13 et 14, la première correspondant à la série des gorges 3 et la seconde à la série des gorges 4 mais, bien entendu, le nombre de rangées pourrait être plus grand, soit pour améliorer la solidité du bracelet, soit pour des raisons esthétiques. Il serait aussi possible, tout en restant dans le cadre de l'invention, de ne placer qu'un crochet par gorge, dont la largeur serait égale à celle d'un élément de liaison. Cette disposition permettrait, en particulier, de réaliser un bracelet de largeur variable en décalant les éléments de liaison les uns par rapport aux autres.In this bracelet, the width of the grooves 3 and 4 is equal to twice the thickness of a connecting element, allowing two hooks to be placed in the same groove. In this way, an arbitrary number of bars can be linked together by placing the connecting elements 5 alternately on the side of the edge of the bars, or on the side of their middle, in the series of grooves 3 and in the series of grooves 4. The connecting elements 5 of a series of grooves are therefore arranged one after the other to form a row. In the example of the bracelet of FIG. 2 there are two rows, 13 and 14, the first corresponding to the series of grooves 3 and the second to the series of grooves 4 but, of course, the number of rows could be greater, either to improve the strength of the bracelet , either for aesthetic reasons. It would also be possible, while remaining within the scope of the invention, to place only one hook per groove, the width of which would be equal to that of a connecting element. This arrangement would make it possible, in particular, to produce a bracelet of variable width by shifting the connecting elements with respect to each other.

Pour améliorer l'aspect du bracelet, au moins une partie des barrettes, réalisées préférentiellement en acier ou en laiton, peuvent être recouvertes, sauf à l'endroit des gorges, par un tube en un matériau différent, par exemple en un métal noble tel que l'or.To improve the appearance of the bracelet, at least some of the bars, preferably made of steel or brass, can be covered, except at the location of the grooves, by a tube made of a different material, for example a noble metal such than gold.

L'examen de la fig. 2 montre que les éléments de liaison 5 d'une rangée, par exemple de la rangée 13, tout en étant alignés, sont cependant décalés les uns par rapport aux autres. Ceci résulte de ce que dans une même gorge se trouvent le crochet 6 d'un élément de liaison et le crochet 7 de l'élément suivant. Cette disposition des éléments de liaison laisse entre deux barrettes adjacentes un espace vide 15 peu esthétique. Cet espace peut facilement être rempli en donnant au pont 8 de l'élément de liaison 5 une épaisseur plus grande.Examination of fig. 2 shows that the connecting elements 5 of a row, for example of row 13, while being aligned, are however offset with respect to each other. This results from the fact that in the same groove are the hook 6 of a connecting element and the hook 7 of the following element. This arrangement of the connecting elements leaves an unattractive empty space between two adjacent bars. This space can easily be filled by giving the bridge 8 of the connecting element 5 a greater thickness.

Pour que le bracelet présente une bonne résistance à la traction, les crochets 6 et 7 d'un élément de liaison 5 doivent avoir une grande rigidité, pouvant rendre leur mise en place dans les gorges 3 et 4 pénible, sinon impossible. Cette difficulté peut être surmontée en créant dans chaque crochet une zone de déformation élastique au voisinage du pont 8 à l'aide, par exemple, d'une ouverture transversale permettant l'élargissement facile des fentes 11 et 12.In order for the bracelet to have good tensile strength, the hooks 6 and 7 of a connecting element 5 must have great rigidity, which can make their installation in the grooves 3 and 4 painful, if not impossible. This difficulty can be overcome by creating in each hook an elastic deformation zone in the vicinity of the bridge 8 using, for example, a transverse opening allowing the easy widening of the slots 11 and 12.

La fig. 3 est une vue d'une partie d'une autre forme d'exécution de l'élément de liaison 5,illustrant les solutions qui permettent d'éviter les problèmes précédents. Dans cette réalisation on distingue un pont 18, similaire au pont 8 mais ayant une épaisseur double, ce supplément d'épaisseur étant disposé de manière à remplir l'espace 15 visible sur la fig. 2. On distingue également sur la fig. 3 un crochet 17, semblable au crochet 7, portant une ouverture transversale 19, située du côté du pont 18. Cette ouverture crée une zone déformable 20 au voisinage du trou 10, facilitant l'élargissement de l'ouverture 12, sans diminuer la résistance à la traction du crochet.Fig. 3 is a view of part of another embodiment of the connecting element 5, illustrating the solutions which make it possible to avoid the above problems. In this embodiment there is a bridge 18, similar to the bridge 8 but having a double thickness, this additional thickness being arranged so as to fill the space 15 visible in FIG. 2. We can also see in fig. 3 a hook 17, similar to the hook 7, carrying a transverse opening 19, located on the side of the bridge 18. This opening creates a deformable zone 20 in the vicinity of the hole 10, facilitating the widening of the opening 12, without reducing the resistance when pulling the hook.

Il est évident que le bracelet articulé qui vient d'être décrit peut subir encore d'autres modifications et se présenter sous diverses variantes évidentes à l'homme de l'art, sans sortir du cadre de la présente invention. En particulier l'élément de liaison, tout en remplissant la même fonction, pourrait prendre d'autres formes que celles décrites et être réalisé, par exemple en acier ou en laiton ou bien encore en un métal noble.It is obvious that the articulated bracelet which has just been described can undergo further modifications and come in various variants obvious to those skilled in the art, without departing from the scope of the present invention. In particular the connecting element, while fulfilling the same function, could take other forms than those described and be made, for example of steel or brass or even of a noble metal.
