Description

La présente invention se réfère à un boîtier de montre, avec un rideau souple destiné à recouvrir le cadran, en particulier à un boîtier de montre bracelet. Un tel boîtier avec un rideau souple est par exemple connu du brevet suisse no 144 054. Le boîtier de montre selon ce brevet comprend en plus du rideau souple un ressort placé sous le mouvement, relié d'une part à une partie fixe et d'autre part à une extrémité du rideau et cherchant constamment à tirer celui-ci sous le mouvement. Ce ressort rend la fabrication plus compliquée et en conséquence plus onéreuse et il augmente le volume du boîtier.The present invention relates to a watch case, with a flexible curtain intended to cover the dial, in particular to a bracelet watch case. Such a case with a flexible curtain is for example known from Swiss Patent No. 144,054. The watch case according to this patent comprises, in addition to the flexible curtain, a spring placed under the movement, connected on the one hand to a fixed part and on the other hand at one end of the curtain and constantly trying to pull it under the movement. This spring makes manufacturing more complicated and consequently more expensive and it increases the volume of the housing.

Le brevet suisse no 142 512 décrit aussi une boîte de montre avec un volet pouvant glisser le long de la partie antérieure ouverte du corps de boîte et comprenant au moins un ressort tendant à faire effacer le volet à l'intérieur de la boîte et des moyens pour maintenir le volet dans sa position fermée. Dans ce cas aussi, le ressort, à boudin, constitue une partie supplémentaire nécessitant un volume supplémentaire et compliquant le montage.Swiss Patent No. 142,512 also describes a watch case with a flap that can slide along the open front part of the box body and comprising at least one spring tending to erase the flap inside the box and means to keep the shutter in its closed position. In this case too, the coil spring constitutes an additional part requiring additional volume and complicating assembly.

En conséquence, le but de la présente invention est de prévoir un boîtier de montre avec un rideau souple de construction simple et ne nécessitant qu'un volume faible additionnel pour pouvoir construire un boîtier de montre plat. Ce but est atteint par un boîtier de montre décrit dans la partie caractéristique de la revendication 1.Consequently, the object of the present invention is to provide a watch case with a flexible curtain of simple construction and requiring only an additional small volume in order to be able to build a flat watch case. This object is achieved by a watch case described in the characteristic part of claim 1.

Le dessin annexé représente, schématiquement et à titre d'exemple une forme d'exécution de l'objet de l'invention.

  • La figure 1 est une vue en perspective de l'objet de l'invention,
  • la figure 2 est une coupe longitudinale de la figure 1,
  • la figure 3 montre un détail de la figure 1, et
  • la figure 4 est un détail agrandi de'la figure 3.
The accompanying drawing shows schematically and by way of example an embodiment of the subject of the invention.
  • FIG. 1 is a perspective view of the subject of the invention,
  • FIG. 2 is a longitudinal section of FIG. 1,
  • Figure 3 shows a detail of Figure 1, and
  • FIG. 4 is an enlarged detail of FIG. 3.

Dans la figure 1 on reconnaît le boîtier 1, une partie d'un bracelet 2 et le rideau souple 3. Le boîtier 1, de forme rectangulaire, comprend une carrure 4 rectangulaire, recevant le mouvement de montre avec le cadran 5, recouvert par une glace 6, par exemple en saphir, et un fond 7. Aux deux côtés longitudinaux de la carrure 4 sont fixées respectivement des plaques de support 8 et 9. Les deux extrémités des plaques de support constituent des anses comportant des ouvertures 10 pour recevoir les barrettes de fixation du bracelet. Une des plaques de support, 8, comporte une ouverture 11 pour la tige de remontoir. Les faces intérieures 12 et 13 de chacune des plaques de support 8 et 9 sont pourvues d'une rainure circulaire 14, c'est-à-dire une rainure continue, parallèle au pourtour de la plaque de support. Dans la figure 2 on reconnaît, fixée aux deux plaques de support une protection 15 à l'extérieur du fond 7 du boîtier de sorte que le rideau souple 3 glisse entre le fond du boîtier 7 et la protection 15. Cette protection 15 peut être, par exemple, constituée comme grille.In Figure 1 we recognize the case 1, part of a bracelet 2 and the flexible curtain 3. The case 1, of rectangular shape, comprises a rectangular middle 4, receiving the watch movement with the dial 5, covered by a crystal 6, for example made of sapphire, and a back 7. Support plates 8 and 9 are fixed respectively to the two longitudinal sides of the middle part. The two ends of the support plates constitute handles comprising openings 10 for receiving the bars. strap fastening. One of the support plates, 8, has an opening 11 for the winding stem. The inner faces 12 and 13 of each of the support plates 8 and 9 are provided with a circular groove 14, that is to say a continuous groove, parallel to the periphery of the support plate. In FIG. 2, it is recognized, fixed to the two support plates, a protection 15 outside the bottom 7 of the housing so that the flexible curtain 3 slides between the bottom of the housing 7 and the protection 15. This protection 15 can be, for example, set up as a grid.

Comme il ressort de la figure 3, le rideau souple est constitué d'éléments tubulaires 16, chaque élément tubulaire recevant un fil 17, dépassant des deux côtés de l'élément. Les éléments tubulaires sont assemblés par des maillons de liaison 18, chaque maillon étant constitué par deux parties sectionnées 19 d'éléments tubulaires, soudées ou brasées ensemble. Pour assembler les éléments tubulaires, une rangée de maillons de liaison 18 est enfilée librement sur les fils, des deux côtés, pour former des paires d'éléments tubulaires. Pour lier les paires entre elles, un maillon de liaison est enfilé sur un fil d'une paire et sur un autre fil de la paire suivante. Un fil seulement est lié à un maillon de liaison et ceci en diagonale, c'est-à-dire que dans la figure 3, le deuxième fil à droite est fixé au premier maillon de liaison 18 et à gauche, le troisième fil est lié au premier maillon de liaison, et de suite. Il en résulte un rideau souple dont les deux grands côtés, c'est-à-dire les fils dépassant les éléments tubulaires et les maillons de liaison coulissent dans les rainures 14. Pour mouvoir le rideau une plaquette 20 est fixée sur une extrémité du rideau souple.As can be seen from FIG. 3, the flexible curtain is made up of tubular elements 16, each tubular element receiving a wire 17, protruding on both sides of the element. The tubular elements are assembled by connecting links 18, each link consisting of two sectioned parts 19 of tubular elements, welded or brazed together. To assemble the tubular elements, a row of connecting links 18 is freely threaded on the wires, on both sides, to form pairs of tubular elements. To link the pairs together, a connecting link is threaded on one wire of one pair and on another wire of the next pair. Only one wire is linked to a connecting link and this diagonally, that is to say that in FIG. 3, the second wire on the right is fixed to the first connecting link 18 and on the left, the third wire is linked to the first link, and immediately. The result is a flexible curtain whose two long sides, that is to say the wires projecting from the tubular elements and the connecting links slide in the grooves 14. To move the curtain, a plate 20 is fixed to one end of the curtain. flexible.

Puisque la rainure 14 est circulaire, c'est-à-dire continue, il est nécessaire de prévoir des moyens du butée pour la position ouverte et la position fermée du rideau souple. Ces moyens de butée 21 sont constitués par les mêmes éléments tubulaires 16 et les fils 17 que le rideau souple, seulement ces éléments tubulaires et les fils sont fixés dans la rainure 14. Une extrémité de ces moyens, positionnée du côté cadran forme la butée 22 pour la position fermée et l'autre extrémité de ces moyens, positionnée du côté fond, forme la butée 23 pour la position ouverte du rideau souple.Since the groove 14 is circular, that is to say continuous, it is necessary to provide stop means for the open position and the closed position of the flexible curtain. These stop means 21 are constituted by the same tubular elements 16 and the wires 17 as the flexible curtain, only these tubular elements and the wires are fixed in the groove 14. One end of these means, positioned on the dial side forms the stop 22 for the closed position and the other end of these means, positioned on the bottom side, forms the stop 23 for the open position of the flexible curtain.

Dans une forme d'exécution il est prévu de fabriquer le boîtier dans sa totalité y compris le rideau souple, entièrement en or ou dans un autre métal noble. La construction du rideau souple se prête en particulier à l'utilisation de l'or, mais il est évident que la construction de ce boîtier n'est pas liée à ce métal et que d'autres matériaux peuvent être utilisés. Du fait de faire coulisser le rideau souple par des fils minces et par le fait qu'il n'y a pas besoin d'un ressort, il est possible de réaliser une construction très plate. Il n'est pas nécessaire de prévoir des élément tubulaires d'une seule pièce, mais il est possible de les réaliser en plusieurs pièces et de prévoir des matériaux différents pour différentes pièces des éléments tubulaires et de ce fait d'introduire des éléments de décoration en utilisant par exemple de l'or de différentes teintes ou d'autre métaux nobles. Il est évident qu'en particulier les plaques de support et la plaquette 20 peuvent être serties de pierres précieuses.In one embodiment, provision is made to manufacture the entire housing including the flexible curtain, entirely of gold or another noble metal. The construction of the flexible curtain is particularly suitable for the use of gold, but it is obvious that the construction of this case is not linked to this metal and that other materials can be used. By sliding the flexible curtain by thin wires and by the fact that there is no need for a spring, it is possible to produce a very flat construction. It is not necessary to provide tubular elements in one piece, but it is possible to produce them in several parts and to provide different materials for different parts of the tubular elements and thereby introducing decorative elements using for example gold of different shades or other noble metals. It is obvious that in particular the support plates and the plate 20 can be set with precious stones.

La construction est particulièrement avantageuse pour une montre bracelet, mais elle n'est pas limitée à une telle montre. Il est aussi possible d'utiliser ce même principe pour une montre de table ou pour un réveil.The construction is particularly advantageous for a wristwatch, but it is not limited to such a watch. It is also possible to use this same principle for a table watch or for an alarm clock.
