Description

Montre dont la boite forme platineWatch with a platinum case

La présente invention se rapporte aux montres dont la boite forme platine. Elle concerne plus particulièrement une boite platine en alliage ou en composé métallique.The present invention relates to watches whose box forms platinum. It relates more particularly to a platinum alloy or metallic compound box.

Une telle montre est décrite dans le brevet suisse 577 199. Elle a pour avantages essentiels d'être plus mince et de nécessiter un nombre réduit de pièces, ce qui diminue son prix de revient. En revanche, la boîte est assez difficile à fabriquer car il faut usiner en même temps une platine et une boite, ce qui, non seulement, a des conséquences sur le coût de fabrication, mais aussi, limite les possibilités sur le plan esthétique.Such a watch is described in Swiss patent 577,199. It has the essential advantages of being thinner and of requiring a reduced number of parts, which reduces its cost price. On the other hand, the box is rather difficult to manufacture because it is necessary to machine at the same time a plate and a box, which, not only, has consequences on the cost of manufacture, but also, limits the possibilities on the esthetic level.

La présente invention a pour but de fournir une montre dont la boîte forme platine, dont la fabrication est simplifiée et qui est susceptible de présenter des effets esthétiques à la fois variés et originaux.The object of the present invention is to provide a watch whose platinum-shaped case, the manufacture of which is simplified and which is capable of presenting aesthetic effects that are both varied and original.

Pour atteindre ce but, la boite de montre selon l'invention est constituée d'un empilement de plaques dont les deux extrêmes forment respectivement le fond de la boite et la lunette portant la glace et dont les autres sont découpées de manière à former des logements dans lesquels les composants de la montre sont fixés individuellement.To achieve this goal, the watch case according to the invention consists of a stack of plates, the two ends of which respectively form the bottom of the case and the bezel carrying the crystal and the others of which are cut so as to form housings. in which the watch components are attached individually.

L'invention sera mieux comprise à la lecture de la description qui va suivre, faite en regard des dessins annexés et donnant, à titre explicatif mais nullement limitatif, une forme avantageuse de réalisation d'une telle montre.The invention will be better understood on reading the description which follows, made with reference to the appended drawings and giving, by way of explanation but in no way limiting, an advantageous embodiment of such a watch.

Sur ces dessins :

  • - la figure 1 représente une montre selon l'invention de face en a, de profil en b;
  • - la figure 2 représente chacune des plaques de la boite de montre; et
  • - les figures 3 et 4 représentent la montre de la figure 1, dans deux états intermédiaires d'assemblage.
In these drawings:
  • - Figure 1 shows a watch according to the invention from the front in a, in profile in b;
  • - Figure 2 shows each of the plates of the watch case; and
  • - Figures 3 and 4 show the watch of Figure 1, in two intermediate states of assembly.

Sur les figures la et 1b, on a représenté schématiquement une montre selon l'invention, avec sa boîte 10, une tige de commande 12, un cadran 14 et des aiguilles 16.In FIGS. 1a and 1b, a watch according to the invention is shown diagrammatically, with its case 10, a control rod 12, a dial 14 and hands 16.

La boîte 10 est formée d'un empilement de 12 plaques, numérotées de 20 à 31, qui sont représentées séparément sur la figure 2. Elles ont grossièrement la forme d'hexagones et leurs dimensions extérieures sont choisies de manière à obtenir un profil de carrure en escalier, tel qu'il apparaît sur les figures la et lb.The box 10 is formed by a stack of 12 plates, numbered from 20 to 31, which are shown separately in FIG. 2. They have roughly the shape of hexagons and their external dimensions are chosen so as to obtain a middle profile. stepped, as it appears in Figures la and lb.

La plaque supérieure 20, qui forme la lunette, comporte une ouverture centrale 32, de forme circulaire, obturée par une glace 33. La fixation de celle-ci est avantageusement réalisée par collage. En variante, la plaque 20 peut, elle-même, être transparente et faire aussi office de glace. La plaque inférieure 31, qui constitue le fond de la boite, est percée d'une ouverture circulaire 34 permettant le passage d'une pile. Cette ouverture se ferme à l'aide d'une trappe 35 qui est, par exemple, vissée dans la plaque 31.The upper plate 20, which forms the bezel, has a central opening 32, of circular shape, closed by a crystal 33. The fixing of the latter is advantageously carried out by gluing. Alternatively, the plate 20 may itself be transparent and also act as ice. The lower plate 31, which constitutes the bottom of the box, is pierced with a circular opening 34 allowing the passage of a stack. This opening closes with a hatch 35 which is, for example, screwed into the plate 31.

La plaque 24 fait office de cadran et porte donc des marques fixes 36 qui définissent les divisions du temps. Elle comporte un guichet 37 permettant la lecture d'un disque de quantième, ainsi qu'un petit trou central 38 destiné à laisser passer des arbres portant les aiguilles 16.The plate 24 acts as a dial and therefore carries fixed marks 36 which define the divisions of time. It includes a window 37 allowing the reading of a date disc, as well as a small central hole 38 intended to allow the passage of trees carrying the hands 16.

Les trois plaques 21, 22 et 23, disposées entre la lunette 20 et la plaque 24 tenant lieu de cadran, comportent des ouvertures circulaires 39, 40 et 41 respectivement, qui définissent un logement pour les aiguilles 16.The three plates 21, 22 and 23, arranged between the bezel 20 and the plate 24 acting as a dial, have circular openings 39, 40 and 41 respectively, which define a housing for the hands 16.

Les six plaques 25, 26, 27, 28 29 et 30, disposées entre la plaque 24 et le fond 31, comportent des ouvertures 42, 43, 44, 45, 46 et 47 respectivement, dont les formes sont telles qu'elles permettent de définir des logements pour des composants du mouvement de montre.The six plates 25, 26, 27, 28 29 and 30, arranged between the plate 24 and the bottom 31, have openings 42, 43, 44, 45, 46 and 47 respectively, whose shapes are such that they allow define housings for components of the watch movement.

Ainsi qu'il ressort des figures 3 et 4, le mouvement comporte essentiellement un module électronique 48 (figure 3), un module moteur 49 (figure 3), un module de quantième 50 (figure 4) et une pile 51.As is apparent from FIGS. 3 and 4, the movement essentially comprises an electronic module 48 (FIG. 3), a motor module 49 (FIG. 3), a date module 50 (FIG. 4) and a battery 51.

Le module électronique 48 (figure 3) comprend un circuit imprimé 52 et, montés sur ce circuit, un résonateur à quartz 53 et un circuit intégré 54. Ce module prend place dans l'ouverture 47 de la plaque 30. Il repose sur la plaque de fond 31 à laquelle il est fixé par collage.The electronic module 48 (FIG. 3) comprises a printed circuit 52 and, mounted on this circuit, a quartz resonator 53 and an integrated circuit 54. This module takes place in the opening 47 of the plate 30. It rests on the plate bottom 31 to which it is fixed by gluing.

Le module moteur 49 (figure 3) a pour base un stator 55 sur lequel sont montés une bobine 56, un rotor 57 et un train d'engrenages 58 entrainant les aiguilles 16. Ce dernier comporte un renvoi de mise à l'heure 58a qui peut être actionné à l'aide de la tige de commande 12. Ce module prend place dans les ouvertures 44, 45, 46 et 47 des plaques 27, 28, 29 et 30. Il repose sur la plaque 30 à laquelle il est fixé par deux clous 59 qui sont soudés sur cette plaque.The motor module 49 (FIG. 3) is based on a stator 55 on which are mounted a coil 56, a rotor 57 and a gear train 58 driving the hands 16. The latter includes a time setting reference 58a which can be actuated using the control rod 12. This module takes place in the openings 44, 45, 46 and 47 of the plates 27, 28, 29 and 30. It rests on the plate 30 to which it is fixed by two nails 59 which are welded to this plate.

Le module de quantième 50 (figure 4) comporte un disque de quantième 60 et une roue 61 d'entraînement de ce disque 60, elle-même entrainée par le train d'engrenages du module moteur. Un pont 62 porte un ressort de sautoir 63 coopérant avec la a denture du disque 60. Deux doigts 64 et 65, portés par le pont 62, assurent le maintien de la roue 61. Trois autres doigts 66, 67 et 68, eux aussi portés par le pont 62, servent à maintenir le disque 60. Avantageusement, le ressort 63 et les doigts 64 à 68 sont venus d'une pièce avec le pont 62. Celui-ci porte, enfin, un rouage de correction 69 qui relie cinématiquement la tige de commande 12 et le disque de quantième 60.The date module 50 (FIG. 4) comprises a date disc 60 and a wheel 61 for driving this disc 60, itself driven by the gear train of the motor module. A bridge 62 carries a jumper spring 63 cooperating with the teeth of the disc 60. Two fingers 64 and 65, carried by the bridge 62, maintain the wheel 61. Three other fingers 66, 67 and 68, also worn by the bridge 62, serve to hold the disc 60. Advantageously, the spring 63 and the fingers 64 to 68 came in one piece with the bridge 62. The latter carries, finally, a corrective train 69 which kinematically connects the control rod 12 and the date disc 60.

Le module de quantième prend place dans les ouvertures circulaires 42 et 43 des plaques 25 et 26. L'ouverture 43 présente des doigts 70 (mieux visibles sur la figure 2) dirigés vers son centre, sur lesquels repose le disque 60. L'ouverture 42 présente, elle aussi, des doigts 71, qui sont plus courts que les doigts 70 et servent à centrer le disque 60. Enfin, le pont 62 est soudé à la plaque 27 en trois points qui n'apparaissent pas sur les figures.The date module takes place in the circular openings 42 and 43 of the plates 25 and 26. The opening 43 has fingers 70 (better visible in FIG. 2) directed towards its center, on which the disc 60 rests. The opening 42 also has fingers 71 which are shorter than fingers 70 and serve to center the disc 60. Finally, the bridge 62 is welded to the plate 27 at three points which do not appear in the figures.

La pile 51, introduite par l'ouverture 34 de la plaque de fond 31, prend place dans les ouvertures 45, 46 et 47 des plaques 28, 29 et 30.The stack 51, introduced through the opening 34 of the bottom plate 31, takes place in the openings 45, 46 and 47 of the plates 28, 29 and 30.

Les trois plaques 25, 26 et 27 présentent des oreilles 72 permettant la fixation d'un bracelet (non représenté).The three plates 25, 26 and 27 have ears 72 allowing the attachment of a bracelet (not shown).

Enfin, la tige de mise à l'heure 12 est montée pivotante dans un tube 73 (figure 3) qui est logé et collé dans des ouvertures 74, 75, 76 et 77 (figure 2) que comportent respectivement les plaques 26, 27, 28 et 29. La tige entraine un renvoi 78 (figure 4), monté sur une bascule (non visible sur les figures) montée pivotante sur la plaque 28. Selon la position de cette bascule, elle-même définie par la position de la tige, le renvoi 78 est libre ou engrène soit avec le rouage de correction de quantième 69 soit avec le renvoi de mise à l'heure 58a.Finally, the time-setting rod 12 is pivotally mounted in a tube 73 (FIG. 3) which is housed and glued in openings 74, 75, 76 and 77 (FIG. 2) that the plates 26, 27 respectively have, 28 and 29. The rod drives a reference 78 (Figure 4), mounted on a rocker (not visible in the figures) pivotally mounted on the plate 28. Depending on the position of this rocker, itself defined by the position of the rod , reference 78 is free or meshes either with the date correction cog 69 or with the time setting reference 58a.

Le choix des matériaux utilisés pour la fabrication des plaques fait intervenir leur coût, leur aspect ainsi que leur résistance mécanique et chimique. L'acier inoxydable, par son coût modéré, son aspect agréable, sa résistance mécanique et chimique et son usinabi- lité, se prête particulièrement bien à la fabrication de la boite précédemment décrite. Les alliages de cuivre ou d'aluminium offrent une grande diversité de coloris grâce aux traitements de surface qu'ils peuvent subir. L'obtention de boites particulièrement résistantes est possible par l'utilisation de plaques en composés métalliques tels que les borures, les nitrures, les carbures de tantale, titane, tungstène, vanadium, etc., ou les oxydes tels que l'alumine.The choice of materials used to manufacture the plates involves their cost, their appearance as well as their mechanical and chemical resistance. Stainless steel, by its moderate cost, its pleasant appearance, its mechanical and chemical resistance and its machinability, lends itself particularly well to the manufacture of the can described above. Copper or aluminum alloys offer a wide variety of colors thanks to the surface treatments they can undergo. Obtaining particularly resistant boxes is possible by the use of plates of metal compounds such as borides, nitrides, tantalum carbides, titanium, tungsten, vanadium, etc., or oxides such as alumina.

Les plaques en métal sont de préférence découpées dans des bandes au moyen d'une étampe progressive qui pratique les ouvertures intérieures avant de découper la forme extérieure. Les plaques en composés métalliques sont fabriquées par frittage, dans des moules qui définissent les formes intérieure et extérieure. Dans les deux cas, les plaques subissent ensuite les opérations de finition, par meulage, brossage et/ou polissage. Les plaques étant planes, il est possible d'automatiser ces opérations. Les plaques subissent enfin, s'il y a lieu, un traitement de surface qui leur confère leur aspect définitif, puis elles sont assemblées.The metal plates are preferably cut into strips by means of a progressive stamp which makes the interior openings before cutting the exterior shape. The metal compound plates are produced by sintering, in molds which define the interior and exterior shapes. In both cases, the plates are then subjected to the finishing operations, by grinding, brushing and / or polishing. As the plates are flat, it is possible to automate these operations. Finally, the plates undergo, if necessary, a surface treatment which gives them their final appearance, then they are assembled.

Pour modifier la forme extérieure de la boite, il suffit de changer une matrice et un poinçon de chacune des étampes progressives, ou la partie extérieure du moule. Ces changements sont peu coûteux, les formes étant en général très simples.To modify the external shape of the box, simply change a die and a punch of each of the progressive stamps, or the external part of the mold. These changes are inexpensive, the forms being generally very simple.

L'assemblage de la montre qui vient d'être décrite peut être réalisé de la manière suivante. Les plaques inférieures 25 à 31 sont d'abord assemblées par collage. Lors de cette opération, le tube 73 est aussi collé dans son logement. On met alors en place dans la platine ainsi constituée le module électronique 48, le module moteur 49, la tige de commande 12, la bascule portant le renvoi 78 et finalement le module de quantième 50. La plaque formant cadran 24 est ensuite collée sur la plaque 25, puis les aiguilles 16 sont mises en place. Il ne reste plus alors qu'à fermer la montre en empilant les plaques 20 à 23 sur la plaque 24. L'assemblage de ces plaques est également réalisé par collage. La pile 51 est finalement introduite dans son logement par l'ouverture 34 qui est alors obturée par la trappe 35.The assembly of the watch which has just been described can be carried out in the following manner. The lower plates 25 to 31 are first assembled by gluing. During this operation, the tube 73 is also glued in its housing. The electronic module 48, the motor module 49, the control rod 12, the lever carrying the reference 78 and finally the date module 50 are then put into place in the plate thus formed. The dial plate 24 is then bonded to the plate 25, then the needles 16 are put in place. It then only remains to close the watch by stacking the plates 20 to 23 on the plate 24. The assembly of these plates is also produced by gluing. The battery 51 is finally introduced into its housing through the opening 34 which is then closed by the hatch 35.

Naturellement il est aussi possible de réaliser l'assemblage des plaques avec des moyens permettant le démontage, tels que des vis et des pieds-vis.Naturally, it is also possible to assemble the plates with means allowing disassembly, such as screws and screw feet.

La présente description a été faite en se référant à une montre à affichage par aiguilles. Il va de soi que l'invention est applicable aussi à la réalisation de montres à affichage électro-optique.The present description has been made with reference to a watch with display by hands. It goes without saying that the invention is also applicable to the production of watches with an electro-optical display.

Il apparaît ainsi que l'invention permet de réduire les coûts de fabrication des montres dont la boite est en métal ou en composé métallique tout en donnant la possibilité de créer des formes de boites originales.It thus appears that the invention makes it possible to reduce the costs of manufacturing watches whose box is made of metal or of metal compound while giving the possibility of creating original box shapes.
