Description

La présente invention est relative à un dispositif d'attache des brins d'un bracelet à une boîte de montre comportant une glace et une carrure, ledit dispositif comprenant des cornes rapportées sur la carrure et des barrettes pour assembler les cornes aux brins du bracelet de façon à permettre l'articulation desdits brins sur lesdites cornes selon le préambule de la revendication 1.The present invention relates to a device for attaching the strands of a bracelet to a watch case comprising a crystal and a middle part, said device comprising horns attached to the middle part and bars for assembling the horns to the strands of the bracelet. so as to allow the articulation of said strands on said horns according to the preamble of claim 1.

On a souvent proposé des cornes rapportées après coup sur la carrure. Dans le cas où la carrure est ronde, ce mode de faire facilite beaucoup l'exécution de la boîte aussi bien pour l'usinage que pour la terminaison, puisque la carrure peut être usinée au tour sans que cet usinage puisse être gêné par des cornes qui feraient partie intégrante de la carrure.Lugs have often been brought back afterwards on the middle. In the case where the middle is round, this mode of operation greatly facilitates the execution of the box both for machining and for termination, since the middle can be machined on the lathe without this machining being able to be hampered by horns which would be an integral part of the middle.

Une telle réalisation est décrite par exemple dans le document CH-A-321188 où la carrure présente une gorge circulaire dans laquelle est engagée une partie arquée de chaque corne qui peut être maintenue en place dans cette gorge de deux façons. La première façon consiste à donner à la section de la gorge et de la partie arquée de la corne une forme qui permet d'accrocher cette corne à la carrure et de la maintenir en place par une lunette. L'autre façon consiste à fixer les cornes à la carrure par des vis qui traversent leurs parties arquées et dont les têtes sont masquées par la lunette. Dans les deux cas ce procédé nécessite un usinage relativement compliqué des cornes d'abord pour la partie s'engageant dans la gorge et ensuite pour la partie apparente et cintrée de la corne qui reçoit le bracelet.Such an embodiment is described for example in document CH-A-321188 where the middle part has a circular groove in which is engaged an arcuate part of each horn which can be held in place in this groove in two ways. The first way is to give the section of the groove and of the arched part of the horn a shape which makes it possible to hang this horn on the middle and to hold it in place by a telescope. The other way is to fix the horns to the middle by screws which cross their arched parts and whose heads are masked by the telescope. In both cases this process requires relatively complicated machining of the horns first for the part engaging in the groove and then for the visible and curved part of the horn which receives the bracelet.

Une autre réalisation apparaît à la lecture du document CH-A-368427 où la corne pénètre dans un logement pratiqué dans la carrure et y est maintenue au moyen d'une goupille de fixation. La corne présentée dans ce document est massive et nécessite également un usinage long et compliqué puisque une de ses extrémités - celle qui est introduite dans la carrure - est cylindrique et l'autre de ses extrémités - celle qui sert à l'attache du bracelet - est parallélipipèdique.Another embodiment appears on reading the document CH-A-368427 where the horn enters a housing made in the middle part and is held there by means of a fixing pin. The horn presented in this document is massive and also requires a long and complicated machining since one of its ends - that which is introduced into the middle part - is cylindrical and the other of its ends - the one used to attach the bracelet - is parallelepiped.

La présente invention a pour but de fournir un dispositif d'attache dont les cornes rapportées peuvent être réalisées de façon beaucoup plus simple que celles décrites dans les documents cités ci-dessus.The object of the present invention is to provide a fastening device, the attached horns of which can be produced in a much simpler manner than those described in the documents cited above.

Pour cela le dispositif d'attache selon l'invention comprend lui aussi des cornes qui ont chacune une portion introduite dans un logement borgne présenté par la carrure de la boîte et des goupilles introduites dans des premiers trous pratiqués dans cette carrure et traversant les cornes pour fixer rigidement celles-ci à la boîte et le but recherché est atteint grâce au fait que dans ce dispositif chaque corne comporte au moins deux plaques minces découpées en forme, juxtaposées et présentant des seconds trous dans lesquels passe l'une des goupilles comme cela est défini dans la partie caractérisante de la revendication 1.For this, the fastening device according to the invention also comprises horns which each have a portion inserted in a blind housing presented by the middle part of the box and pins introduced in the first holes made in this middle part and passing through the horns for rigidly fix these to the box and the desired goal is achieved thanks to the fact that in this device each horn comprises at least two thin plates cut into shape, juxtaposed and having second holes through which one of the pins passes as is defined in the characterizing part of claim 1.

A noter que l'on connaît, grâce au document FR-A-2 554 691, un dispositif d'attache d'un bracelet à une boîte de montre qui comprend pour chaque brin ou chaque extrémité de ce bracelet un élément formé de deux pièces juxtaposées, dont une portion est introduite dans un logement de la carrure de la montre pour assembler cet élément avec la carrure et une barrette pour attacher le brin ou l'extrémité de bracelet à cet élément. Toutefois, dans ce dispositif l'élément en question n'est pas une corne qui est fixée rigidement à la carrure par une goupille mais un élément qui est tenu par un pivot autour duquel il peut tourner de façon à être mobile vers le dessus de la boîte et ceci afin de faciliter la fixation de la montre au poignet. De plus, les pièces de l'élément qui ne sont qu'au nombre de deux sont forcément des pièces épaisses qui ne peuvent pas être obtenues simplement par étampage mais, par exemple, par fraisage. Si ces pièces étaient minces elles ne pourraient pas résister longtemps aux contraintes de flexion et de torsion auxquelles elles seraient soumises au moment de la fixation de la montre au poignet et pendant que cette montre serait portée. Au contraire, dans le cas du dispositif d'attache selon l'invention, les plaques minces juxtaposées sont liées rigidement à la carrure et, par conséquent, entre elles et le nombre de plaques par corne peut être choisi en fonction de leur épaisseur, du nombre de cornes, etc., ce qui fait que ces cornes peuvent être aussi solides que des cornes massives classiques.Note that we know, from document FR-A-2 554 691, a device for attaching a bracelet to a watch case which comprises for each strand or each end of this bracelet an element formed of two parts juxtaposed, a portion of which is introduced into a housing of the middle part of the watch to assemble this element with the middle part and a bar for attaching the strand or the end of the bracelet to this element. However, in this device the element in question is not a horn which is rigidly fixed to the middle part by a pin but an element which is held by a pivot around which it can rotate so as to be movable above the box and this in order to facilitate the fixing of the watch to the wrist. In addition, the parts of the element which are only two in number are necessarily thick parts which cannot be obtained simply by stamping but, for example, by milling. If these parts were thin, they would not be able to withstand for a long time the flexural and torsional stresses to which they would be subjected when the watch was attached to the wrist and while this watch was being worn. On the contrary, in the case of the fastening device according to the invention, the juxtaposed thin plates are rigidly linked to the middle part and, consequently, between them and the number of plates per horn can be chosen according to their thickness, the number of horns, etc., which means that these horns can be as solid as conventional solid horns.

On a représenté en figure 1 une montre-bracelet comportant une boîte 3 à laquelle sont attachés deux brins 1 et 2 d'un bracelet. La boîte 3 comporte une carrure 10, une glace 9 à travers laquelle on distingue des aiguilles 12 d'affichage de l'heure et un fond 11. Le dispositif d'attache comprend pour chacun des brins 1 et 2 une corne 4 qui est rapportée sur la carrure. Une barrette 5 assemble la corne au brin de façon à permettre, de manière connue en soi, l'articulation du brin sur la corne.FIG. 1 shows a wristwatch comprising a box 3 to which two strands 1 and 2 of a bracelet are attached. The box 3 comprises a middle part 10, a crystal 9 through which there are needles 12 for displaying the time and a bottom 11. The attachment device comprises for each of the strands 1 and 2 a horn 4 which is attached on the middle. A bar 5 assembles the horn to the strand so as to allow, in a manner known per se, the articulation of the strand on the horn.

Selon une caractéristique essentielle de l'invention la corne 4 comporte au moins deux plaques 6 découpées en forme et juxtaposées puis introduites partiellement dans un logement borgne 7 pratiqué dans la carrure 10. Une goupille 8 est reçue à la fois dans un trou 14 pratiqué dans la carrure et dans des seconds trous 15 pratiqués dans les plaques pour fixer la corne à la boîte. Par logement borgne il faut entendre ici un logement pratiqué dans l'épaisseur de la carrure et laissant de la matière entre l'intérieur de la boîte et l'extérieur de celle-ci. Ce logement comporte un fond 25 (voir figure 3).According to an essential characteristic of the invention, the horn 4 comprises at least two plates 6 cut in shape and juxtaposed and then partially introduced into a blind housing 7 made in the middle 10. A pin 8 is received both in a hole 14 made in the middle part and in second holes 15 made in the plates to fix the horn to the box. By blind housing is meant here a housing made in the thickness of the middle and leaving material between the inside of the box and the outside thereof. This housing has a bottom 25 (see Figure 3).

La figure 3 qui est une coupe selon la ligne III - III de la figure 1, montre bien comment est ajustée une plaque 6 de la corne 4 par rapport à la carrure 10. Dans la carrure 10, on pratique le logement borgne 7 qui présente le fond 25. On introduit alors les plaques dans le logement, puis on chasse la goupille 8 d'abord dans le premier trou 14 pratiqué dans la carrure puis dans le second trou 15 pratiqué dans la plaque et enfin dans le premier trou 14 pratiqué dans la carrure (voir aussi figure 1). La figure 3 montre encore que le brin 2 du bracelet est fixé à la corne 4 par l'intermédiaire de la barrette 5 introduite dans un trou 16 pratiqué dans les plaques 6 de la corne 4.Figure 3 which is a section along line III - III of Figure 1, shows how is adjusted a plate 6 of the horn 4 relative to the middle 10. In the middle 10, we practice the blind housing 7 which has the bottom 25. The plates are then introduced into the housing, then the pin 8 is chased first in the first hole 14 made in the middle part then in the second hole 15 made in the plate and finally in the first hole 14 made in the middle (see also Figure 1). FIG. 3 also shows that the strand 2 of the bracelet is fixed to the horn 4 by means of the bar 5 introduced into a hole 16 made in the plates 6 of the horn 4.

Pour priver la plaque 6 de toute mobilité quand elle est fixée à la carrure, on s'arrange pour qu'une tranche de la plaque 6 vienne s'appuyer élastiquement contre le fond 25 du logement 7 quand la goupille 8 est introduite dans les trous 14 et 15. Cela est avantageusement réalisé, comme on peut le voir en figure 3, en pratiquant sur la tranche de la plaque un dégagement 21 qui définit deux zones d'appui 18 et 19, les moyens permettant la déformation élastique de la tranche consistant à affaiblir la plaque entre le fond du dégagement 21 et le trou 15, ce qui provoque le fléchissement de la tranche quand la goupille 8 est introduite dans les trous 14 et 15.To deprive the plate 6 of any mobility when it is fixed to the middle part, it is arranged so that a slice of the plate 6 comes to bear elastically against the bottom 25 of the housing 7 when the pin 8 is inserted into the holes 14 and 15. This is advantageously achieved, as can be seen in FIG. 3, by making a clearance 21 on the edge of the plate which defines two support zones 18 and 19, the means allowing the elastic deformation of the consistent edge weakening the plate between the bottom of the clearance 21 and the hole 15, which causes the edge to bend when the pin 8 is introduced into the holes 14 and 15.

Les figures 1 et 3 montrent encore que l'on peut mettre à profit la présence des cornes 4 pour fixer de manière étanche la glace 9 sur la carrure 10. Dans ce but la plaque 6 comporte une saillie ou surplomb 17 qui mord sur la glace et l'appuie sur la carrure. L'étanchéité est assurée par une garniture 13 pincée entre la glace et la carrure.Figures 1 and 3 also show that we can take advantage of the presence of the horns 4 to seal the glass 9 on the middle 10. For this purpose the plate 6 has a projection or overhang 17 which bites on the glass and presses it on the middle. The seal is ensured by a lining 13 pinched between the crystal and the middle part.

La figure 4 est une coupe montrant une variante d'exécution de la coupe illustrée en figure 3. La seule différence consiste à fixer la glace 9 dans un logement 26 situé sur le haut de la carrure 10, un joint 27 assurant l'étanchéité, la plaque 6 ne contribuant en rien à la fixation de la glace sur la carrure.FIG. 4 is a section showing an alternative embodiment of the section illustrated in FIG. 3. The only difference consists in fixing the glass 9 in a housing 26 located on the top of the middle part 10, a seal 27 ensuring the tightness, the plate 6 contributing in no way to the fixing of the crystal on the middle.

La figure 2 montre une vue de face d'un second mode d'exécution du dispositif d'attache selon l'invention. Ici chaque brin du bracelet est attaché à la boîte 3 au moyen de deux cornes 4 présentant chacune deux plaques 6. La fixation des plaques est réalisée de façon semblable à ce qui a été décrit plus haut.Figure 2 shows a front view of a second embodiment of the fastening device according to the invention. Here each strand of the bracelet is attached to the case 3 by means of two horns 4 each having two plates 6. The plates are fixed in a similar manner to what has been described above.

Les figures 1 et 2 montrent encore des cornes 4 fabriquées d'une pluralité de plaques 6 découpées et juxtaposées. Dans ces exemples, les plaques formant la corne présentent toutes une même découpure. Dans le cas de la figure 5 par contre, chaque corne est formée de trois plaques 30, 31 et 32 dont les découpures sont différentes et ceci dans le but de rechercher une esthétique originale. Si les trois plaques sont fixées à la boîte par la goupille 8 déjà décrite plus haut, le brin 2 du bracelet n'est attaché aux cornes 4 que par l'extrémité de la plaque 32 au moyen de la barrette 5.Figures 1 and 2 also show horns 4 made of a plurality of plates 6 cut and juxtaposed. In these examples, the plates forming the horn all have the same cutout. In the case of FIG. 5 on the other hand, each horn is formed of three plates 30, 31 and 32 whose cutouts are different and this in order to seek an original aesthetic. If the three plates are fixed to the box by the pin 8 already described above, the strand 2 of the bracelet is only attached to the horns 4 by the end of the plate 32 by means of the bar 5.

On se reportera maintenant aux figures 6 et 7. Dans ces deux figures les cornes sont faites de plaques 33 et 34 découpées puis pliées en forme de U. Dans le cas de la figure 6 les extrémités libres du U s'appuyent dans le fond du logement borgne pratiqué dans la carrure et la base du U est arrangée pour recevoir la barrette d'articulation du brin du bracelet. Inversément dans la figure 7, c'est la base du U qui s'appuie dans le fond du logement borgne alors que ce sont les extrémités libres du U qui sont arrangées pour recevoir la barrette d'articulation du brin du bracelet.We will now refer to Figures 6 and 7. In these two figures the horns are made of plates 33 and 34 cut and then folded into a U shape. In the case of Figure 6 the free ends of the U are supported in the bottom of the blind housing made in the middle and the base of the U is arranged to receive the hinge bar of the bracelet strand. Conversely in FIG. 7, it is the base of the U which is supported in the bottom of the blind housing whereas it is the free ends of the U which are arranged to receive the articulation bar of the strand of the bracelet.

Les formes d'exécution qui ont été décrites montrent que le dispositif revendiqué et faisant appel à des plaques découpées, permet une foule de variantes grâce auxquelles l'aspect final de la montre peut être modifiée. On mentionnera de surcroît que les plaques peuvent être découpées dans une même bande au moyen d'une étampe. Dans ce cas toutes les plaques auraient la même coloration. Le matériau de base peut être de l'acier ou de l'or. On peut envisager aussi l'alternance de deux matériaux, par exemple acier et or pour obtenir un aspect bicolore. Quel que soit le matériau utilisé, on remarquera que les plaques formant la corne sont faciles à réaliser, sans usinage compliqué, puisque venues d'étampe. De ce fait, le dispositif d'attache est bon marché tout en présentant une allure attrayante et nouvelle.The embodiments which have been described show that the device claimed and using cut plates, allows a host of variants by which the final appearance of the watch can be modified. It should also be mentioned that the plates can be cut from the same strip by means of a stamp. In this case all the plates would have the same coloring. The base material can be steel or gold.

La figure 8 montre une exécution particulière de la plaque 6. On reconnaît ici les zones d'appui 18 et 19, la saillie 17, le dégagement 21 et les trous 15 et 16 recevant respectivement la goupille de fixation de la plaque sur la carrure et la barrette de fixation du brin du bracelet à la plaque. En dehors de la configuration décrite ci-dessus, la plaque présente un évidement 20, découpé en même temps que le contour extérieur de la plaque, cet évidement permettant une économie de matière, particulièrement si la plaque est faite en or.FIG. 8 shows a particular embodiment of the plate 6. Here we recognize the support zones 18 and 19, the projection 17, the clearance 21 and the holes 15 and 16 respectively receiving the pin for fixing the plate to the middle part and the strap strand for attaching the bracelet to the plate. Apart from the configuration described above, the plate has a recess 20, cut at the same time as the external contour of the plate, this recess allowing a saving of material, particularly if the plate is made of gold.
