Abstract

The link comprises a cylindrical body (16) and a plug (18) which each have at their ends first and second fixing parts. One fixing part is female (34) and the other male (28a). One of the fixing parts comprises a boss (40) and the other a groove (32) which receives the boss to form a notch assembly.

Description

La présente invention se rapporte aux barrettes pour bracelets de montre à maillons, du type comportant un corps, de forme générale cylindrique et un bouchon, le corps et le bouchon étant respectivement munis, à l'une de leurs extrémités, d'un premier et d'un second organe de fixation, l'un des organes étant de type femelle, l'autre de type mâle, engagé dans l'organe de type femelle. Ces barrettes permettent l'assemblage des maillons de manière articulés.The present invention relates to bars for watch straps to links, of the type comprising a body, of generally cylindrical shape and a plug, the body and the plug being respectively provided, at one of their ends, a first and a second fixing member, one of the members being of the female type, the other of the male type, engaged in the type organ female. These bars allow the assembly of the links so articulated.

Une barrette de ce type est, par exemple décrite dans le brevet CH 661 416. Le corps de la barrette est munie, à ses deux extrémités, d'une vis formant le premier organe, de type mâle. Chacune de ces extrémités coopère avec un bouchon comportant un trou borgne taraudé, formant l'organe femelle. L'assemblage des maillons se fait donc en engageant le corps de la barrette dans les trous coaxiaux de deux maillons voisins et en fixant les bouchons par vissage. A cet effet, ces derniers comportent, à leur extrémité opposée à celle munie du trou borgne, d'une fente permettant d'engager un tournevis. De la sorte, n'importe quel vendeur disposant d'un tel outil peut effectuer la mise de longueur. Dans ce cas, le risque existe que ce vendeur, craignant de rayer le bracelet, ne visse pas le bouchon à fond, de sorte que celui-ci se détache du corps et que le bracelet se démonte.A bar of this type is, for example described in patent CH 661,416. body of the bar is provided at its two ends with a screw forming the first organ, male type. Each of these ends cooperates with a plug with a tapped blind hole, forming the female member. The assembly of the links is therefore done by engaging the body of the bar in the coaxial holes of two neighboring links and fixing the plugs by screwing. To this end, the latter comprise, at their end opposite to that provided with the blind hole, a slot allowing to engage a screwdriver. Of the so any vendor with such a tool can bet length. In this case, the risk exists that this seller, fearing to scratch the bracelet, do not screw the cap fully, so that it comes off the body and the bracelet disassembles.

Cela est non seulement préjudiciable pour le porteur, mais également pour le fabricant dont l'image est ternie.This is not only detrimental to the wearer, but also to the manufacturer whose image is tarnished.

C'est pourquoi, seuls quelques maillons sont ainsi généralement équipés, les autres étant munis de barrettes indémontables. Une barrette de ce type fait l'objet du brevet CH 676 781. Elle est montée dans des trous borgnes que comportent les maillons disposés aux extrémités, le corps des maillons étant déformé pour assurer la fixation. Avec une telle solution, il est, bien sûr, impossible de modifier la longueur du bracelet ou, simplement, de changer un maillon qui serait abímé.This is why, only a few links are thus generally equipped, the others being fitted with non-removable bars. A bar of this type does the subject of patent CH 676 781. It is mounted in blind holes that have the links arranged at the ends, the body of the links being deformed to secure. With such a solution, it is, of course, impossible to change the length of the bracelet or, simply, to change a link that would be damaged.

Le but de la présente invention est de proposer une barrette garantissant un assemblage qui ne peut être démonté accidentellement, tout en permettant une mise de longueur du bracelet. Ce but est atteint grâce au fait que l'un des organes de fixation comporte un bossage, l'autre une gorge destinée à recevoir le bossage, pour former, ensemble, un assemblage à cran, et que le bouchon présente une surface extérieure uniforme. De la sorte, bouchon et corps forment ensemble un assemblage de type rivet. Le démontage peut se faire par usinage du bouchon. Cela est réalisable au moyen d'un posage simple et d'un foret destiné à percer le bouchon. La barrette est, ensuite, séparée du bracelet au moyen d'un poinçon. Lors de cette opération, la barrette est détruite.The object of the present invention is to propose a bar guaranteeing a assembly which cannot be dismantled accidentally, while allowing length setting of the bracelet. This goal is achieved thanks to the fact that one of the fasteners has a boss, the other a groove for receiving the boss, to form, together, a notched assembly, and that the plug has a uniform exterior surface. In this way, plug and body form together a rivet type assembly. Disassembly can be done by machining of the plug. This can be done by simple installation and a drill intended to pierce the plug. The bar is then separated from the bracelet at by means of a punch. During this operation, the bar is destroyed.

Après avoir enlevé un ou plusieurs maillons, le bracelet peut être assemblé en fixant les maillons avec une barrette neuve. De la sorte, la mise de longueur ne peut se faire que par une personne munie d'un équipement adéquat, avec pour résultat un assemblage au moyen de barrettes neuves, c'est-à-dire garantissant des conditions d'assemblage homogènes.After removing one or more links, the bracelet can be assembled in fixing the links with a new bar. In this way, the length setting does not can only be done by a person with adequate equipment, with result an assembly by means of new bars, that is to say guaranteeing homogeneous assembly conditions.

Afin de simplifier au maximum l'assemblage, dans un premier mode de réalisation le corps présente une tête dans sa partie opposée à son extrémité munie de l'organe de fixation, dont la forme extérieure est sensiblement la même que celle du bouchon. De la sorte, le corps peut être glissé dans les maillons par un côté, le bouchon amené par l'autre côté, l'assemblage se faisant en appliquant une force axiale forçant le cran.In order to simplify assembly as much as possible, in a first mode of realization the body has a head in its part opposite to its end provided with the fixing member, the external shape of which is substantially the same as that of the cap. In this way, the body can be slid into the links on one side, the plug brought in on the other side, assembly being done by applying an axial force forcing the notch.

De manière avantageuse, un manchon peut être disposé sur le corps, dans l'espace compris entre la tête et le bouchon. De la sorte, l'articulation des maillons d'un bracelet muni de telles barrettes est garantie, quel que soit la façon dont le bouchon est chassé sur le corps. Advantageously, a sleeve can be placed on the body, in the space between the head and the cap. In this way, the articulation of links of a bracelet fitted with such bars is guaranteed, whatever the way the plug is flushed out of the body.

Si le mode de réalisation défini ci-dessus facilite l'assemblage, la mise de longueur du bracelet est rendue plus difficile, du fait qu'il n'est pas possible de savoir de quel côté se trouve le bouchon. Pour pallier cet inconvénient, dans un autre mode de réalisation, chacune des extrémités du corps est munie d'un organe de fixation, chaque organe coopérant avec un bouchon.If the embodiment defined above facilitates assembly, placing length of the bracelet is made more difficult, since it is not possible to find out which side the plug is on. To overcome this drawback, in a another embodiment, each of the ends of the body is provided with a fixing member, each member cooperating with a plug.

Un manchon est avantageusement disposé sur le corps, dans l'espace compris entre les deux bouchons, pour favoriser l'articulation des maillons, comme expliqué plus haut.A sleeve is advantageously placed on the body, in the space included between the two plugs, to favor the articulation of the links, as explained above.

De manière avantageuse, le corps de la barrette est muni de l'organe mâle et le bouchon de l'organe femelle. De plus, la gorge est pratiquée dans le corps de la barrette et le bossage dans l'organe femelle que comporte le bouchon. De la sorte, le corps de la barrette, fabriqué par décolletage, a un diamètre constant, à l'exception de la gorge dont il est muni. Le bouchon se présente ainsi sous la forme d'un bouchon, l'organe femelle définissant un trou borgne dont le fond est de faible épaisseur. Il est, de la sorte possible de facilement percer le bouchon pour engager un poinçon et déchasser le corps.Advantageously, the body of the bar is provided with the male member and the plug of the female organ. In addition, the throat is practiced in the body of the bar and the boss in the female member that includes the plug. Of the so, the body of the bar, made by bar turning, has a constant diameter, at with the exception of the throat with which it is provided. The plug thus appears under the shape of a plug, the female organ defining a blind hole whose bottom is thin. It is thus possible to easily pierce the plug to engage a punch and release the body.

Dans une autre variante, le bouchon est muni de l'organe mâle et le corps de l'organe femelle. De la sorte, le corps peut être réalisé au moyen d'un tube, les bouchons étant décolletés. Dans ce cas, il est avantageux que le bossage soit réalisé dans l'organe femelle que comporte le corps, la gorge étant pratiquée dans l'organe mâle dont est muni le bouchon.In another variant, the plug is provided with the male member and the body of the female organ. In this way, the body can be produced by means of a tube, the caps being turned. In this case, it is advantageous if the boss is produced in the female organ that the body comprises, the throat being practiced in the male organ with which the plug is provided.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel les figures 1 à 3 représentent chacune deux maillons d'un bracelet assemblés au moyen d'une barrette selon l'invention, différente pour chaque figure. Other advantages and characteristics of the invention will emerge from the description which follows, made with reference to the appended drawing, in which the Figures 1 to 3 each represent two links of a bracelet assembled to the means of a bar according to the invention, different for each figure.

Sur les trois figures, on peut voir un maillon 10, avec deux poutres parallèles entre elles 10a et une traverse 10b, formant ensemble un H, un maillon parallélépipédique 12 et une barrette 14. Cette dernière est de forme générale cylindrique, d'axe A-A, orienté parallèlement à la traverse 10b. Elle comporte un corps 16 et au moins un bouchon 18.In the three figures, we can see a link 10, with two parallel beams between them 10a and a crosspiece 10b, together forming an H, a link parallelepiped 12 and a bar 14. The latter is of general shape cylindrical, of axis A-A, oriented parallel to the cross-member 10b. It involves a body 16 and at least one plug 18.

Les poutres 10a et la traverse 10b définissent deux découpes 10c de forme rectangulaire, dont la longueur est égale à L et la largeur à 1. Ces découpes 10c sont destinées à recevoir les maillons 12, chaque maillon 12 étant engagé dans deux découpes voisines. Les maillons 12 ont une longueur L' et une largeur 2l', L' et l' étant respectivement légèrement plus faibles que L et l.The beams 10a and the crossbeam 10b define two cutouts 10c of rectangular shape, the length of which is equal to L and the width of 1. These cutouts 10c are intended to receive the links 12, each link 12 being engaged in two adjacent cutouts. The links 12 have a length L ' and a width 2l ', L ' and l ' being slightly smaller respectively than L and l .

Le maillon 10 est percé de deux paires de trous 20 et 22, cylindriques et traversant les poutres 10a de part en part, les trous 20, respectivement 22 étant coaxiaux. Le maillon 12 est percé de deux trous 24 et 26, cylindriques et le traversant de part en part.The link 10 is pierced with two pairs of holes 20 and 22, cylindrical and passing through the beams 10a right through, the holes 20, respectively 22 being coaxial. The link 12 is pierced with two cylindrical holes 24 and 26 and the crossing right through.

Lorsqu'un bracelet est monté, chaque maillon 10 est attenant à deux maillons 12, les trous 20 du maillon 10 étant coaxiaux au trou 24 de l'un des maillons 12 et les trous 22 coaxiaux aux trous 26 de l'autre maillon 12. De même, chaque maillon 12 est attenant à deux maillons 10. Le bracelet est ainsi formé d'une alternance de maillons 10 et 12.When a bracelet is mounted, each link 10 is attached to two links 12, the holes 20 of the link 10 being coaxial with the hole 24 of one of the links 12 and the holes 22 coaxial with the holes 26 of the other link 12. Similarly, each link 12 is attached to two links 10. The bracelet is thus formed of a alternating links 10 and 12.

Les trous 20 et 24 d'une part, 22 et 26 d'autre part, servent de logement aux barrettes 14, qui assurent l'assemblage articulé des maillons les uns avec les autres.The holes 20 and 24 on the one hand, 22 and 26 on the other hand, serve as housing for bars 14, which ensure the articulated assembly of the links with the other.

Dans le mode de réalisation représenté sur la figure 1, les trous 20 et 22 présentent un diamètre Da et les trous 24 et 26 un diamètre Db, plus petit que Da. In the embodiment shown in Figure 1, the holes 20 and 22 have a diameter Da and the holes 24 and 26 a diameter Db , smaller than Da .

Le corps 16 de la barrette 14 est formé d'une tige 28 et d'une tête 30. La tige 28 est engagée dans le trou 24 du maillon 12 et comporte une extrémité 28a qui dépasse du trou 24 pour s'engager dans l'un des trous 20 du maillon 10 attenant. Elle présente un diamètre légèrement inférieur à Db, de manière à ce que le maillon 12 puisse y pivoter librement. Elle est munie, dans sa portion engagée dans le trou 20, d'une gorge 32 dont la fonction sera précisée plus loin.The body 16 of the bar 14 is formed of a rod 28 and a head 30. The rod 28 is engaged in the hole 24 of the link 12 and has an end 28a which protrudes from the hole 24 to engage in the one of the holes 20 of the adjoining link 10. It has a diameter slightly less than Db , so that the link 12 can pivot there freely. It is provided, in its portion engaged in the hole 20, with a groove 32 whose function will be explained below.

La tête 30 est engagée dans l'autre des trous 20. Elle est de forme générale cylindrique, de diamètre légèrement inférieur à Da, de manière à ce que la barrette 14 puisse tourner librement dans le maillon 10.The head 30 is engaged in the other of the holes 20. It is of generally cylindrical shape, with a diameter slightly less than Da , so that the bar 14 can rotate freely in the link 10.

Le bouchon 18 est entièrement logé dans le trou 20 dans lequel dépasse la tige 28. Il présente la forme d'un capuchon, avec un trou borgne 34, définit par une paroi 36 et une extrémité 38. Le trou 34 présente un diamètre sensiblement égal à Db, de manière à ce que la tige 28 puisse y être engagée. La paroi 36 forme un bossage 40 disposé de manière à coopérer avec la gorge 32 lorsque le bouchon 18 est en place, pour former ensemble un assemblage à cran, l'extrémité 28a formant un organe mâle et le trou 34 du bouchon 18 un organe femelle.The plug 18 is entirely housed in the hole 20 in which the rod 28 protrudes. It has the shape of a cap, with a blind hole 34, defined by a wall 36 and an end 38. The hole 34 has a substantially equal diameter to Db , so that the rod 28 can be engaged therein. The wall 36 forms a boss 40 arranged so as to cooperate with the groove 32 when the plug 18 is in place, to form together a notched assembly, the end 28a forming a male member and the hole 34 of the plug 18 a female member. .

Pour réaliser un bracelet, il suffit de disposer les maillons 10 et 12 en alternance, puis d'engager les corps 16 dans les trous 20 et 24, respectivement 22 et 26, et enfin de chasser les bouchons 18.To make a bracelet, you just need to have the links 10 and 12 in alternation, then to engage the bodies 16 in the holes 20 and 24, respectively 22 and 26, and finally to remove the plugs 18.

La mise de longueur du bracelet se fait en retirant au moins un maillon 10 et un maillon 12. A cet effet, il est nécessaire de défaire deux barrettes. Cela ne peut se faire qu'en détruisant ces barrettes. En effet, tant la tête que le bouchon présentent une surface uniforme, de sorte qu'il n'est pas possible d'exercer une force de traction entre le bouchon et le corps. The length setting of the bracelet is done by removing at least one link 10 and one link 12. For this purpose, it is necessary to undo two bars. It cannot only by destroying these bars. Indeed, both the head and the cap have a uniform surface, so it is not possible to exercise a tensile force between the plug and the body.

Aussi, pour effectuer une mise de longueur, le bracelet est disposé sur un posage qui le maintien sur la tranche. Un foret, coaxial à l'axe A-A de la barrette à dégager, perce le bouchon 18 à son extrémité 38, jusqu'à atteindre le trou borgne 32. Un poinçon, disposé dans le trou pratiqué par le foret, permet, au moyen d'un marteau, de chasser le corps 16 hors du bouchon 18.Also, to make a length setting, the bracelet is placed on a laying which keeps it on the edge. A drill, coaxial with the axis A-A of the bar to release, pierce the plug 18 at its end 38, until reaching the blind hole 32. A punch, placed in the hole made by the drill, allows, by means of a hammer, to drive the body 16 out of the plug 18.

Après avoir enlevé le nombre de maillons nécessaire, les deux parties du bracelet sont assemblées au moyen d'une barrette neuve, assemblée au bracelet comme expliqué plus haut. De la sorte, la qualité de l'assemblage est garantie.After removing the necessary number of links, the two parts of the bracelet are assembled by means of a new bar, assembled to the bracelet as explained above. In this way, the quality of the assembly is guaranteed.

On retrouve, dans la portion de bracelet représenté à la figure 2 la plupart des composants de la figure 1, portant les mêmes références. Toutefois, le maillon 12 et la barrette 14 sont différents.We find, in the bracelet portion shown in Figure 2 most of the components of FIG. 1, bearing the same references. However, the link 12 and the bar 14 are different.

La barrette 14 comprend un corps 16, constitué d'une tige 28 dont les deux extrémités 28a et 28b sont engagées dans les trous 20 et sont munies d'une gorge 32, et deux bouchons 18, chacun fixé sur l'une des extrémités 28a et 28b. Une telle configuration facilite la mise de longueur du bracelet, du fait que l'opération de perçage peut se faire indifféremment de l'un et de l'autre côté. De plus, le corps 16 est de forme très simple, nécessitant un minimum d'enlèvement de matière, ce qui réduit le coût de fabrication des barrettes.The bar 14 comprises a body 16, consisting of a rod 28, the two of which ends 28a and 28b are engaged in the holes 20 and are provided with a groove 32, and two plugs 18, each fixed to one of the ends 28a and 28b. Such a configuration facilitates the length setting of the bracelet, because the drilling operation can be carried out on either side. Of more, the body 16 is very simple in shape, requiring a minimum material removal, which reduces the cost of manufacturing the bars.

Un manchon cylindrique 42 est disposé sur le corps 16, sa longueur étant sensiblement égale à celle L' du maillon 12 dans lequel il est engagé. Les trous 26 présentent un diamètre Dc supérieur au diamètre Db. Ils servent de logement au manchon 42, dont le diamètre extérieur est légèrement inférieur à Dc et le diamètre intérieur égal à Db.A cylindrical sleeve 42 is disposed on the body 16, its length being substantially equal to that L ' of the link 12 in which it is engaged. The holes 26 have a diameter Dc greater than the diameter Db . They serve as housing for the sleeve 42, the outside diameter of which is slightly less than Dc and the inside diameter of which is equal to Db .

De la sorte, les bouchons 18 peuvent être chassés sur le corps 16 jusqu'à être en butée contre le manchon 42, l'articulation des maillons 10 et 12 étant réalisée entre le maillon 12 et le manchon 42. In this way, the plugs 18 can be removed from the body 16 until they are in abutment against the sleeve 42, the articulation of the links 10 and 12 being produced between the link 12 and the sleeve 42.

Il va de soi que le manchon 42 décrit en référence à la figure 2 peut sans autre être associé au mode de réalisation de la figure 1. Il suffit alors d'ajuster le diamètre des trous des maillons 12, de manière à ce que le manchon 42 qui y est logé puisse pivoter librement.It goes without saying that the sleeve 42 described with reference to FIG. 2 can without further be associated with the embodiment of FIG. 1. It suffices then to adjust the diameter of the holes in the links 12, so that the sleeve 42 therein is housed can rotate freely.

La figure 3 montre également une portion de bracelet avec des maillons 10 et 12 et une barrette assurant leur assemblage, semblable à la variante de la figure 2. Dans cette variante, les organes mâles des assemblages à cran sont solidaires des bouchons 18 alors que les organes femelles sont formés par le corps 16. Plus précisément, le corps 16 est réalisé au moyen d'un tube percé de part en part d'un trou 16a, formant des organes femelles et ayant un diamètre intérieur Dd. La paroi du tube, aux extrémités, est déformée pour définir, à l'intérieur du trou 16a, les bossages 40. De plus, les bouchons 18 comportent chacun une tige 44, de diamètre extérieur légèrement inférieur à Dd, de manière à ce qu'elle puisse être introduite dans le corps 16, et munie de la gorge 32 qui coopère avec le bossage 40.FIG. 3 also shows a portion of bracelet with links 10 and 12 and a bar ensuring their assembly, similar to the variant of FIG. 2. In this variant, the male members of the notched assemblies are integral with the plugs 18 while the female organs are formed by the body 16. More specifically, the body 16 is produced by means of a tube pierced right through with a hole 16a, forming female organs and having an internal diameter Dd . The wall of the tube, at the ends, is deformed to define, inside the hole 16a, the bosses 40. In addition, the plugs 18 each have a rod 44, of outside diameter slightly less than Dd , so that 'it can be introduced into the body 16, and provided with the groove 32 which cooperates with the boss 40.

Cette variante offre l'avantage d'une grande simplicité dans la fabrication du corps 16. La mise de longueur est, par contre plus difficile.This variant offers the advantage of great simplicity in the manufacture of body 16. The setting of length is, on the other hand more difficult.

La présente invention peut, bien entendu, faire l'objet de nombreuses variantes, sans pour autant sortir du cadre de l'invention. Il est ainsi possible de combiner de manière différentes les différentes solutions décrites plus haut. De plus, la fixation par cran pourrait être réalisée avec des formes de gorges et de bossages différents.The present invention can, of course, be the subject of numerous variants, without departing from the scope of the invention. It is thus possible to combine in different ways the different solutions described above. In addition, the fixing by notch could be carried out with shapes of grooves and bosses different.

La forme des maillons peut faire l'objet de nombreuses variantes, connues ou inconnues. The shape of the links can be the subject of numerous variants, known or unknown.

Les matériaux utilisés pour la fabrication des barrettes 14 peuvent être de n'importe quel type, dans la mesure où il ne pose pas de problème de corrosion ou d'allergie.The materials used for the manufacture of the bars 14 can be of any type, as long as there is no corrosion problem or allergy.
