Description

La présente invention a pour objet une boîte de montre-bracelet comprenant un fond et une carrure-lunette et munie d'un bracelet intégré en cuir fixé à la boîte par l'intermédiaire d'un cadre métallique monté dans un logement annulaire de la boîte, dans lequel il est retenu par une partie de la boîte.The present invention relates to a wristwatch box comprising a bottom and a middle-bezel and provided with an integrated leather strap fixed to the box by means of a metal frame mounted in an annular housing of the box. , in which it is retained by part of the box.

Une montre de ce type est connu du document US-A-2 559 238. Dans cette montre, le cadre est constitué par un anneau de section ronde maintenu entre un fond calotte et une lunette. Le cuir du bracelet est attaché directement sur l'anneau autour duquel il peut pivoter comme il le ferait sur une barette conventionnelle. En outre, l'anneau est visible latéralement, de telle sorte que le bracelet ne paraît pas véritablement être intégré à la boîte.A watch of this type is known from document US-A-2,559,238. In this watch, the frame consists of a ring of round section held between a cap bottom and a bezel. The leather of the bracelet is attached directly to the ring around which it can pivot as it would on a conventional bar. In addition, the ring is visible laterally, so that the bracelet does not really appear to be integrated into the box.

Il est connu d'autre part de fixer une boîte de montre à un bracelet d'un seul tenant (CH-B-536 083 et FR-A-1 598 983). Dans ce cas, le bracelet est visible sur tout le pourtour de la boîte. En outre, le cuir a tendance à former un coude à l'endroit où il quitte la boîte, coude qui peut entraîner, par fatigue, une cassure du cuir.It is also known to attach a watch case to a bracelet in one piece (CH-B-536 083 and FR-A-1 598 983). In this case, the bracelet is visible around the entire periphery of the box. In addition, the leather tends to form an elbow where it leaves the box, an elbow which can cause, by fatigue, the leather to break.

La présente invention a pour but de réaliser une intégration plus complète du bracelet en cuir à la boîte tout en réduisant le risque de cassure du bracelet près de ses points d'attache.The present invention aims to achieve a more complete integration of the leather strap to the box while reducing the risk of breakage of the bracelet near its attachment points.

Ce but est atteint par les caractéristiques de la boîte définie dans la revendication. Le cadre auquel est fixé le bracelet est invisible et la flexibilité des languettes permet au bracelet de prendre une courbure régulière, sans coude.This object is achieved by the characteristics of the box defined in the claim. The frame to which the bracelet is attached is invisible and the flexibility of the tabs allows the bracelet to take a regular curvature, without elbow.

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

  • La figure 1 représente une vue en plan de la montre complète.
  • La figure 2 en représente une vue de profil.

  • La figure 4 représente une vue en coupe partielle selon IV-IV de la figure 1.
  • La figure 5 représente une vue en plan du cadre de fixation du bracelet.
The accompanying drawing shows, by way of example, an embodiment of the invention.
  • Figure 1 shows a plan view of the complete watch.
  • Figure 2 shows a side view.
  • FIG. 3 represents a partial section along III-III of FIG. 1.
  • FIG. 4 represents a partial sectional view along IV-IV of FIG. 1.
  • FIG. 5 represents a plan view of the strap fixing frame.

La montre-bracelet représentée aux figures 1 et 2 comprend une boîte 1 à laquelle sont fixés de façon intégrée deux brins 2 et 3 d'un bracelet en cuir dont on n'a pas représenté le fermoir.The wristwatch shown in FIGS. 1 and 2 comprises a box 1 to which two strands 2 and 3 of a leather strap are attached in an integrated manner, the clasp of which has not been shown.

La boîte 1 comprend une carrure-lunette 4 à laquelle est fixé à pression un fond plat 5 auquel est soudé un cadre d'encageage 6 destiné à supporter un mouvement 7 surmonté d'un cadran 8. Le cadre d'encageage 6 est muni extérieurement en au moins deux points opposés d'un cran 9 venant s'accrocher sur un bourrelet 10 de la carrure-lunette 4. Cette carrure-lunette 4 présente une partie 4a formant rehaut et un cran de glace 4b destiné à recevoir une glace plane 11. Comme ceci est particulièrement visible à la figure 4, la carrure-lunette 4 présente une gorge annulaire de section rectangulaire 12 s'étendant sur tout son pourtour et s'ouvrant sur la face plane inférieure de la carrure-lunette. La paroi extérieure de cette gorge 12 présente toutefois deux interruptions correspondant à la largeur des brins de bracelet, comme ceci est visible à la figure 3, partie de droite. Cette même paroi présente en outre une encoche arrondie 13 pour le passage de la tige de la couronne de mise à l'heure. Dans la gorge 12, est logé un cadre métallique 14, par exemple en laiton, représenté seul à la figure 5. La gorge 12 étant complètement fermée par le fond 5, le cadre 14 est retenu et caché à l'intérieur de ia'carrure-tunette 4. A trois heures, le cadre 14 présente une encoche 15 en forme de U pour le passage de la tige de mise à l'heure. Le cadre 14 présente deux étroites rainures horizontales 16 et 17 dans lesquelles sont encastrées deux languettes flexibles en bronze béryllium, l'une de ces languettes 18 étant représentée aux figures 3 et 5. Ces languettes sont en outre soudées au cadre 14. L'extrémité du brin de bracelet 3 entoure complètement la languette 18 et le cuir est collé sur cette languette. Le brin 2 est fixé de la même manière sur et autour de l'autre languette non représentée. L'épaisseur totale du bracelet au point d'encastrement des languettes est égale à deux épaisseurs de cuir et à l'épaisseur de la languette qui n'est que de 0,1 mm. L'épaisseur totale du bracelet à cet endroit, qui détermine la hauteur du cadre 14 est donc relativement faible. Elle est par exemple de l'ordre de 1,40 mm et n'a pratiquement pas d'influence sur la hauteur totale de la boîte.The box 1 comprises a middle part-bezel 4 to which a flat bottom 5 is fixed by pressure to which is welded a casing frame 6 intended to support a movement 7 surmounted by a dial 8. The casing frame 6 is provided externally at at least two opposite points of a notch 9 which hooks onto a bead 10 of the middle part-bezel 4. This middle part-bezel 4 has a part 4a forming an elevation and a notch of ice 4b intended to receive a flat glass 11 As is particularly visible in FIG. 4, the middle part-bezel 4 has an annular groove of rectangular section 12 extending over its entire periphery and opening onto the lower flat face of the middle part-bezel. The outer wall of this groove 12 however has two interruptions corresponding to the width of the bracelet strands, as can be seen in FIG. 3, right part. This same wall also has a rounded notch 13 for the passage of the stem of the time-setting crown. In the groove 12, is housed a metal frame 14, for example brass, shown alone in Figure 5. The groove 12 being completely closed by the bottom 5, the frame 14 is retained and hidden inside ia'carrure -tunette 4. At three o'clock, the frame 14 has a notch 15 in the shape of a U for the passage of the time-setting rod. The frame 14 has two narrow horizontal grooves 16 and 17 in which are embedded two flexible tabs in beryllium bronze, one of these tabs 18 being shown in Figures 3 and 5. These tabs are further welded to the frame 14. The end of the bracelet strand 3 completely surrounds the tongue 18 and the leather is bonded to this tongue. The strand 2 is fixed in the same way on and around the other tab, not shown. The total thickness of the bracelet at the point where the tabs are fitted is equal to two thicknesses of leather and the thickness of the tongue which is only 0.1 mm. The total thickness of the bracelet at this location, which determines the height of the frame 14 is therefore relatively small. It is for example of the order of 1.40 mm and has practically no influence on the total height of the box.

Le cadre 14 permet de fabriquer séparément des bracelets d'un seul tenant avec leur moyen de fixation à la boîte. Par la simple mise en place du cadre 14 dans son logement, les deux brins du bracelet se trouvent fixés simultanément et correctement à la boîte.The frame 14 makes it possible to separately manufacture bracelets in one piece with their means of attachment to the box. By simply placing the frame 14 in its housing, the two strands of the bracelet are fixed simultaneously and correctly to the box.
