Description

La présente invention est relative à une montre comportant un boîtier fait d'une pièce et équipé d'une glace montée étanche sur le boîtier, une coiffe couvrant au moins partiellement ladite montre et un bracelet comportant deux demi-bracelet fixés de part et d'autre du boîtier au moyen d'axes autour desquels peuvent pivoter les demi-bracelets.The present invention relates to a watch comprising a case made in one piece and equipped with a crystal mounted waterproof on the case, a cap at least partially covering said watch and a bracelet comprising two half-straps fixed on either side. other of the case by means of axes around which the half-bracelets can pivot.

On a souvent proposé une montre ou un boîtier de montre-bracelet recouverte par une coiffe.We have often proposed a watch or a wristwatch case covered by a cap.

Le brevet CH-A-558 040 décrit une boîte de montre comportant une coiffe de protection en matière extra-dure. Dans cette construction la coiffe est maintenue en place par des vis perpendiculaires au plan de la boîte, traversant la carrure-lunette et prenant dans des plots taraudés rapportés sous la coiffe. Ici la coiffe présente une section droite assez compliquée due à la présence des plots tarau­dés. La carrure-lunette doit être réalisée selon une forme spéciale pour être adaptée à la coiffe qui la surmonte.Patent CH-A-558,040 describes a watch case comprising a protective cap made of extra hard material. In this construction, the cap is held in place by screws perpendicular to the plane of the case, passing through the middle of the bezel and taking in threaded studs attached under the cap. Here the cap has a fairly complicated cross section due to the presence of tapped studs. The middle-bezel must be made in a special shape to be adapted to the cap which surmounts it.

Le brevet CH-A-517 963 (US-A-3 242 664) décrit une boîte de montre revêtue par une coiffe en carbure métallique faite d'une partie annulaire entourant la glace et deux oreilles diamétralement opposées recouvrant les cornes d'attache d'un bracelet. La partie annulaire et les oreilles sont brasées respectivement sur la boîte et sur les cornes. Cette construction nécessite un outillage spécial pour fixer la coiffe sur la boîte de montre et l'on observera qu'une fois la coiffe fixée, cette dernière est indémontable du moins en utilisant de simples outils.Patent CH-A-517,963 (US-A-3,242,664) describes a watch case coated with a metal carbide cap made of an annular part surrounding the crystal and two diametrically opposed ears covering the attachment horns of 'a bracelet. The annular part and the ears are brazed respectively on the box and on the horns. This construction requires special tools to fix the cap on the watch case and it will be observed that once the cap has been fixed, the latter is non-removable at least using simple tools.

Le boîtier décrit dans le brevet US-A-4 396 298 contient un module électronique pour l'affichage de l'heure. Ce boîtier comporte un fond, une partie élastique interposée entre le fond et le module et un couvercle. Des barrettes élastiques engagées dans des rebords du fond maintiennent le module dans le fond de la boîte. Les mêmes barrettes servent à fixer le couvercle sur le fond. Le bracelet est fixé à la boîte au moyen d'oreilles levées dans le fond. Cette construction est compliquée et nécessite plusieurs pièces pliées et embouties. Le couvercle ne constitue pas à proprement parler une coiffe, mais bien plutôt une partie constitutive de la boîte.The housing described in US-A-4 396 298 contains an electronic module for displaying the time. This housing has a bottom, an elastic part interposed between the bottom and the module and a cover. Elastic bars engaged in bottom flanges hold the module in the bottom of the box. The same bars are used to fix the cover on the bottom. The bracelet is attached to the box by means of ears lifted at the bottom. This construction is complicated and requires several folded and stamped parts. The lid is not strictly speaking a cap, but rather a constituent part of the box.

Le document DE-C-1 099 773 décrit une lunette interchangeable adaptée à une montre-bracelet. Ici la lunette est maintenue sur la montre à l'aide d'un bracelet fait d'une pièce. Le bracelet pénètre dans un premier orifice pratiqué dans la lunette, passe ensuite entre une première barrette porté par une première paire de cornes de la boîte de montre et la carrure de cette dernière, longe le fond du boîtier, passe encore entre une seconde barrette portée par une seconde paire de cornes de la boîte de montre et la carrure de ladite boîte et émerge de la lunette par un second orifice pratiqué dans ladite lunette. Dans cette construction les barrettes ne servent pas à attacher la lunette sur la boîte. D'autre part la construction proposée est compliquée et lourde et modifie considéra­blement l'aspect de la boîte de montre originale.Document DE-C-1 099 773 describes an interchangeable bezel suitable for a wristwatch. Here the bezel is held on the watch using a one-piece bracelet. The strap enters a first opening in the bezel, then passes between a first bar carried by a first pair of horns from the watch case and the middle of the latter, runs along the bottom of the case, again passes between a second worn bar. by a second pair of horns from the watch case and the middle part of said box and emerges from the bezel through a second orifice made in said bezel. In this construction, the bars are not used to attach the bezel to the box. On the other hand, the proposed construction is complicated and heavy and considerably modifies the appearance of the original watch case.

Le document FR-A-1 092 554 propose surtout un fermoir pour bracelet fait d'une seule bande, fermoir combiné avec le boîtier de la montre. Le boîtier de la montre est monté pivotant par rapport au cadre-lunette au moyen d'une charnière, ladite charnière ne servant nullement à attacher le bracelet au boîtier.Document FR-A-1 092 554 above all proposes a clasp for a bracelet made of a single band, a clasp combined with the watch case. The watch case is pivotally mounted relative to the bezel frame by means of a hinge, said hinge in no way serving to attach the strap to the case.

Enfin la pièce d'horlogerie montrée dans le document FR-A- 2 329 002 présente une sorte de lunette qui fait partie intégrante du boîtier de la montre et contribue à son étanchéité et non une coiffe interchangeable habillant un boîtier fait d'une pièce comme c'est le cas dans la présente invention.Finally, the timepiece shown in document FR-A-2 329 002 has a kind of bezel which is an integral part of the watch case and contributes to its water resistance and not an interchangeable cap covering a case made of one piece as this is the case in the present invention.

La présente invention est caractérisé par le fait que les axes portant les deux demi-bracelets servent conjointement de moyen de fixation de la coiffe au boîter. Les avantages d'une telle disposition apparaîtront clairement à la lecture de la description qui va suivre et à l'examen du dessin qui illustre à titre d'exemple et dans lequel :

  • - la figure 1 est une vue en perspective éclatée de la montre selon l'invention et
  • - la figure 2 est une coupe selon la ligne II-II de la figure 1 si l'on suppose toutes les pièces assemblées les unes aux autres.
The present invention is characterized in that the pins carrying the two half-bracelets serve jointly as a means of fixing the cap to the case. The advantages of such an arrangement will become clear on reading the description which follows and on examining the drawing which illustrates by way of example and in which:
  • FIG. 1 is an exploded perspective view of the watch according to the invention and
  • - Figure 2 is a section along line II-II of Figure 1 if we assume all the parts assembled together.

La montre 1 de la figure 1 comprend essentiellement un boîtier 2 contenant un dispositif d'affichage de l'heure, une glace 3 laissant apparaître des aiguilles 4, une coiffe 5 susceptible de couvrir au moins partiellement la montre et un bracelet formé ici de deux demi-bracelets 6 et 7 susceptibles d'être fixés au boîtier par des moyens de fixation 8 et 18. La figure 1 fait voir immédiatement que les moyens de fixation 8 et 18 qui relient respectivement les demi-bracelets 6 et 7 au boîtier servent conjointement de moyen de fixation de la coiffe 5 au boîtier 2.Watch 1 of FIG. 1 essentially comprises a case 2 containing a device for displaying the time, a crystal 3 revealing hands 4, a cap 5 capable of at least partially covering the watch and a bracelet formed here of two half-bracelets 6 and 7 capable of being fixed to the case by fixing means 8 and 18. FIG. 1 immediately shows that the fixing means 8 and 18 which respectively connect the half-bracelets 6 and 7 to the case serve jointly of means for fixing the cover 5 to the housing 2.

Dans le mode d'exécution présenté à la figure 1, le boîtier 2 comporte deux paires de cornes 9 et 10 entre lesquelles sont arti­culés respectivement les demi-bracelets 6 et 7. Le demi-bracelet 6 est articulé autour d'un axe 8 enfilé dans des premiers perçages 11 et 12 pratiqués dans les cornes 9. Le demi-bracelet 7 est articulé de la même manière entre les cornes 10 pourvues des perçages 19 et 20. La figure 1 montre aussi que la coiffe 5 comporte deux paires d'oreilles 13 et 14. La paire d'oreilles 13 est pourvue de seconds perçages 15 et 16 qui sont également traversés par l'axe 8. Il en est de même pour la paire d'oreilles 14 qui sont pourvues des perçages 21 et 22. Ainsi l'axe 8 sert à la fois de fixation du demi-bracelet 6 sur le boîtier 2 et de fixation de la coiffe 5 sur ledit boîtier 2. L'axe 18 joue le même rôle pour le demi-bracelet se trouvant sur le côté opposé de la montre.In the embodiment presented in FIG. 1, the case 2 comprises two pairs of horns 9 and 10 between which the half-bracelets 6 and 7 are hinged respectively. The half-bracelet 6 is articulated around a threaded axis 8 in first holes 11 and 12 made in the horns 9. The half-bracelet 7 is articulated in the same way between the horns 10 provided with the holes 19 and 20. Figure 1 also shows that the cap 5 has two pairs of ears 13 and 14. The pair of ears 13 is provided with second holes 15 and 16 which are also crossed by the axis 8. It is the same for the pair of ears 14 which are provided with holes 21 and 22. Thus the pin 8 is used both for fixing the half-bracelet 6 on the case 2 and for fixing the cap 5 on the said case 2. The pin 18 plays the same role for the half-bracelet located on the opposite side of the watch.

La figure 2 qui est une coupe selon la ligne II-II de la figure 1 en supposant toutes les parties assemblées, montre les cornes 9 portées par le boîtier 2 et les premiers perçages 11 et 12 pratiqués dans les cornes 9.FIG. 2 which is a section along line II-II of FIG. 1 assuming all the parts assembled, shows the horns 9 carried by the housing 2 and the first bores 11 and 12 made in the horns 9.

Le boîtier 2 et les cornes 9 sont entourées par la coiffe 5 dont apparaît la paire d'oreilles 13 munie des seconds perçages 15 et 16. L'axe 8 qui est enfilé dans les cornes 9 du boîtier maintient à la fois la coiffe 5 et le demi-bracelet 6 solidaires dudit boîtier. Ainsi la coiffe et le demi-bracelet sont assemblés au boîtier en une seule opération qui consiste, une fois la coiffe posée sur le boîtier, à enfiler l'axe à travers les divers perçages dont il a été question plus haut.The housing 2 and the horns 9 are surrounded by the cap 5 from which appears the pair of ears 13 provided with second holes 15 and 16. The pin 8 which is threaded in the horns 9 of the housing maintains both the cap 5 and the half-bracelet 6 secured to said case. Thus the cap and the half-bracelet are assembled to the case in a single operation which consists, once the cap placed on the case, to thread the axis through the various holes which have been discussed above.

Les axes 8 et 18 peuvent être des goupilles chassées dans les premiers perçages 11, 12 et 19, 20. La figure 2 montre que la goupille 8 émerge des cornes 9 pour pénétrer dans les seconds perçages 15 et 16 des oreilles. Dans cette construction les oreilles 13 recouvrent les parois extérieures des cornes 9. On pourrait cependant envisager d'autres solutions, celle par exemple qui consisterait à disposer les oreilles 13 sur les parois intérieures des cornes 9.The axes 8 and 18 can be pins driven into the first holes 11, 12 and 19, 20. Figure 2 shows that the pin 8 emerges from the horns 9 to penetrate into the second holes 15 and 16 of the ears. In this construction, the ears 13 cover the outer walls of the horns 9. However, other solutions could be envisaged, for example that which would consist in placing the ears 13 on the inner walls of the horns 9.

L'axe 8, au lieu d'être une goupille chassée, pourrait être une barrette à ressort. Dans ce cas les seconds perçages 15 et 16 devraient être adaptés au diamètre des pivots d'une telle barrette, c'est-à-dire être d'un diamètre plus petite que le diamètre des premiers perçages 11 et 12.The axis 8, instead of being a driven pin, could be a spring bar. In this case, the second holes 15 and 16 should be adapted to the diameter of the pivots of such a bar, that is to say be of a diameter smaller than the diameter of the first holes 11 and 12.

La coiffe 5 qui est présentée à la figure 2 entoure la glace 3 et s'étend jusqu'au bas de la tranche verticale du boîtier 2. Dans certains cas on pourrait faire buter la partie verticale de la coiffe contre des rebords qui seraient pratiqués dans la périphérie inférieure du boîtier. Cette disposition donnerait une meilleure assise à la coiffe, de même qu'elle pourrait être avantageuse pour des raisons purement esthétiques.The cover 5 which is presented in FIG. 2 surrounds the crystal 3 and extends to the bottom of the vertical edge of the housing 2. In certain cases, the vertical part of the cover could be made to abut against flanges which would be made in the lower periphery of the housing. This arrangement would give a better seat to the cap, just as it could be advantageous for purely aesthetic reasons.

La coiffe 5 peut être réalisée en n'importe quel matériau, comme du plastique, du métal ou encore de la céramique. Si la coiffe présente une épaisseur assez mince, 0,3 mm pour donner un chiffre elle pourrait habiller un boîtier de forme exthétique réputée pour son succès commercial, sans avoir à toucher à cette forme, le but étant de donner l'impression que la montre est réalisée en une matière différente de celle connue primitivement. Par exemple, la montre Swatch (marque déposée), connue mondialement pour sa forme particulière et son prix très bas, pourrait constituer le boîtier de base défini dans la présente invention, boîtier qui serait revêtu d'une coiffe donnant à cette montre un aspect esthétique nouveau sans changer sa forme réputée et sans modifier sensiblement son prix de vente. Ainsi le boîtier de cette montre connue resterait le même, en matière plastique et fabriqué en grandes séries. Une coiffe en or ou en métal doré changerait son aspect esthétique en donnant l'impression que la montre est faite en métal et cela sans rien changer à sa forme.The cap 5 can be made of any material, such as plastic, metal or even ceramic. If the cap has a fairly thin thickness, 0.3 mm to give a figure, it could dress an aesthetically shaped case known for its commercial success, without having to touch this shape, the aim being to give the impression that the watch is made of a different material from that originally known. For example, the Swatch watch (registered trademark), known worldwide for its particular shape and its very low price, could constitute the basic case defined in the present invention, case which would be coated with a cap giving this watch an aesthetic appearance. new without changing its deemed form and without significantly modifying its selling price. Thus the case of this known watch would remain the same, made of plastic and produced in large series. A gold or gold metal cap would change its aesthetic appearance by giving the impression that the watch is made of metal and that without changing anything in its shape.

Les avantages cités ci-dessus sont dus avant tout au fait que la coiffe décrite se monte sans difficulté sur le boîtier et sans qu'il faille recourir à d'autre moyens que ceux qui sont utilisés normalement pour fixer le bracelet au boîtier. Tous les moyens connus jusqu'ici pour modifier l'aspect de la montre ne pouvaient être mis en oeuvre que par le fabricant lui-même par vissage, brasage, collage, etc. Une modification de l'aspect de la montre après sa sortie de fabrication n'était ainsi plus possible. Au contraire de cela, la présente invention rend possible une telle modification en tout cas par l'horloger revendeur, si ce n'est par le porteur de la montre. Pour cela et selon le procédé d'assemblage revendiqué, on pose la coiffe sur le boîtier, on présente un demi-­bracelet entre une des paires de cornes, on enfile l'axe dans les premiers et seconds perçages dont sont pourvues respectivement les cornes et les oreilles et on répète les mêmes opérations pour l'autre demi-bracelet.The advantages mentioned above are due above all to the fact that the cap described is easily mounted on the case and without having to resort to other means than those which are normally used to fix the bracelet to the case. All the means known hitherto for modifying the appearance of the watch could only be implemented by the manufacturer himself by screwing, soldering, bonding, etc. A change in the appearance of the watch after it left production was no longer possible. On the contrary to this, the present invention makes such modification possible in any case by the watchmaker dealer, if not by the wearer of the watch. For this and according to the claimed assembly method, the cap is placed on the case, a half-bracelet is presented between one of the pairs of horns, the pin is threaded into the first and second holes which are provided respectively with the horns and the ears and the same operations are repeated for the other half bracelet.

Il a été fait état dans la description ci-dessus d'une double paire de cornes attenantes au boîtier. La présente invention n'est pas limitée à cette exécution particulière. On pourrait avoir entre les deux cornes d'une attache de bracelet une, voire deux cornes supplémentaires comme cela est exposé par exemple, dans le document CH-A- 647 917 (US-A-4 624 581).Reference has been made in the above description to a double pair of horns adjoining the housing. The present invention is not limited to this particular embodiment. There could be one, or even two additional horns between the two horns of a bracelet attachment, as explained, for example, in document CH-A- 647,917 (US-A-4,624,581).

La coiffe présentée en figure 1 montre une ouverture 25 qui entoure la glace 3. Sans qu'il soit nécessaire de l'illustrer, on comprendra que cette ouverture pourrait comprendre une grille de protection qui aurait pour but de protéger la glace. Cette grille, à larges mailles, pourrait être étampée en même temps que l'on étampe la coiffe elle-même. Le centre de la grille pourrait également inclure une pastille, ronde ou de forme, sur laquelle pourrait apparaître une marque.The cap presented in FIG. 1 shows an opening 25 which surrounds the glass 3. Without it being necessary to illustrate it, it will be understood that this opening could include a protective grid which would have the aim of protecting the ice. This grid, with large meshes, could be stamped at the same time as the cap itself is stamped. The center of the grid could also include a patch, round or shaped, on which a mark could appear.
