Description

Boîte de montre Watch box
La présente invention concerne les boîtes de montre, notamment les boîtes de montres-bracelets, et vise à intégrer, mieux que ce n'était le cas jusqu'à maintenant dans ce domaine de l'industrie, les progrès récents dans la précision et la régularité de la mise en forme des matières plastiques, en proposant un mode de construction qui s'adapte facilement aux différentes gammes de montres et permet d'améliorer dans une mesure inattendue la compétitivité de ces produits sur le marché .The present invention relates to watch cases, in particular wristwatch boxes, and aims to integrate, better than has been the case until now in this field of industry, recent advances in precision and regularity of the shaping of plastics, by proposing a construction method which adapts easily to the different ranges of watches and allows to improve in an unexpected measure the competitiveness of these products on the market.
Dans ce but, la boîte de montre selon l'invention est caractérisée par le fait que son constituant principal est un insert en une pièce comportant un corps annulaire entourant et supportant le mouvement de la montre, et un prolongement tubulaire supérieur limitant l'espace entre le cadran et le verre, et entourant le verre, ledit prolongement supérieur étant serré latéralement contre le verre par une lunette supérieure de manière à assurer 1 ' étanchéité de la boîte autour du verre .For this purpose, the watch case according to the invention is characterized in that its main constituent is a one-piece insert comprising an annular body surrounding and supporting the movement of the watch, and an upper tubular extension limiting the space between the dial and the glass, and surrounding the glass, said upper extension being clamped laterally against the glass by an upper bezel so as to seal the box around the glass.
L'insert peut présenter en outre un prolongement tubulaire inférieur qui est engagé autour d'une pastille de fond et serré contre cette dernière par une lunette inférieure de manière à assurer l' étanchéité du fond de la boîte.The insert may also have a lower tubular extension which is engaged around a bottom pad and clamped against the latter by a lower bezel so as to seal the bottom of the box.
Le corps annulaire dudit insert peut porter un tube latéral pour le passage étanche de la tige de commande du mouvement .The annular body of said insert can carry a lateral tube for the sealed passage of the movement control rod.
Ledit insert peut être réalisé par injection ou moulage en une matière plastique appropriée, ladite matière plastique pouvant être choisie parmi le hytrel et la grilamide. Une bague, jouant le rôle de réhaut, peut être intercalée entre le verre et le cadran.Said insert can be produced by injection or molding in a suitable plastic material, said plastic material being able to be chosen from hytrel and grilamide. A ring, playing the role of flange, can be interposed between the glass and the dial.
L' insert peut comporter un epaulement annulaire de réception de la périphérie du cadran et, en saillie de cet epaulement, une goupille parallèle au prolongement supérieur, traversant le réhaut et orientant le cadran.The insert may include an annular shoulder for receiving the periphery of the dial and, projecting from this shoulder, a pin parallel to the upper extension, passing through the flange and orienting the dial.
Le prolongement tubulaire supérieur de l'insert peut présenter, répartis sur son pourtour intérieur, des bourrelets de centrage du réhaut .The upper tubular extension of the insert may have, distributed around its inner periphery, flanges for centering the flange.
L'insert peut présenter une face latérale externe apparente sous la lunette supérieure, avec deux logements diamétralement opposés sur six heures et sur douze heures, pour l'accrochage des brins du bracelet.The insert may have an external lateral face visible under the upper bezel, with two diametrically opposite housings over six hours and twelve hours, for hanging the strands of the bracelet.
Enfin, la face latérale externe de l'insert peut être engagée dans un brancard porte-cornes retenu entre les lunettes supérieure et inférieure.Finally, the external lateral face of the insert can be engaged in a stretcher carrying horns retained between the upper and lower glasses.

Dans toutes les formes d'exécution représentées au dessin on trouve les mêmes cinq pièces principales : un insert 1, une lunette supérieure 2, un verre 3, une lunette inférieure 4 et une pastille de fond 5.In all of the embodiments shown in the drawing, the same five main parts are found: an insert 1, an upper bezel 2, a glass 3, a lower bezel 4 and a bottom patch 5.
L'insert 1 est le constituant principal. De préférence, il sera formé d'une seule pièce, en une matière plastique appropriée, par exemple le hytrel ou la grilamide, par injection ou moulage sous pression. On a constaté en effet qu'une telle matière utilisée dans des moules de haute qualité permettait de produire la pièce voulue avec toute la précision requise et à des coûts très réduits. L'insert comporte un corps annulaire 6 avec une face interne 7 qui est ajustée au diamètre extérieur du mouvement de montre 8 et présente un décrochement pour recevoir et retenir le filet de platine du mouvement 8. Le corps annulaire 6 se raccorde vers le haut à un prolongement tubulaire supérieur 9 qui présente la particularité d'être suffisamment mince et souple pour que son extrémité puisse être engagée autour du verre 3, de structure usuelle, tout en étant comprimée radialement par la face intérieure de la lunette supérieure 2. Le prolongement 9 venu d'une pièce avec le reste de l'insert joue donc le rôle d'un joint d' étanchéité pour le verre.Insert 1 is the main constituent. Preferably, it will be formed in one piece, from a suitable plastic material, for example hytrel or grilamide, by injection or pressure molding. It has been found in fact that such a material used in high quality molds makes it possible to produce the desired part with all the required precision and at very reduced costs. The insert comprises an annular body 6 with an internal face 7 which is adjusted to the outside diameter of the watch movement 8 and has a recess for receiving and retaining the platinum thread of the movement 8. The annular body 6 is connected upwards to an upper tubular extension 9 which has the particularity of being sufficiently thin and flexible so that its end can be engaged around the glass 3, of usual structure, while being compressed radially by the inner face of the upper bezel 2. The extension 9 coming from one piece with the rest of the insert therefore plays the role of a seal for the glass.
De la même manière, le corps annulaire 6 de l'insert 1 possède encore un prolongement tubulaire inférieur 10 qui s'engage sur le pourtour de la pastille de fond 5. Ce prolongement est serré contre la périphérie de la pastille de fond par l'engagement de la lunette inférieure 4. Les ajustages seront calculés de manière que l'ensemble lunette inférieure, insert, pastille de fond soit indissociable. Il en sera de même pour l'assemblage du verre et de la lunette supérieure avec interposition du prolongement tubulaire 9. La pastille de fond 5 peut être en métal ou en une matière minérale transparente ou opaque. Les lunettes 2 et 4 seront de préférence en métal . Les arêtes internes supérieure ou inférieure des lunettes seront chanfreinées de manière à recouvrir les bords respectivement supérieur et inférieur des prolongements tubulaires et à masquer les parties jouant le rôle de joints d' étanchéité . Comme on peut le constater, ces détails se retrouvent dans toutes les formes d'exécution décrites.Similarly, the annular body 6 of the insert 1 also has a lower tubular extension 10 which engages around the periphery of the bottom pad 5. This extension is clamped against the periphery of the bottom pad by the engagement of the lower bezel 4. The adjustments will be calculated in such a way that the lower bezel, insert, bottom patch is inseparable. It will be the same for the assembly of the glass and the upper bezel with interposition of the tubular extension 9. The bottom pad 5 may be made of metal or of a transparent or opaque mineral material. The glasses 2 and 4 will preferably be made of metal. The upper or lower internal edges of the spectacles will be chamfered so as to cover the respectively upper and lower edges of the tubular extensions and to mask the parts playing the role of seals. As can be seen, these details are found in all the embodiments described.
Une autre particularité se retrouvant dans toutes les formes d'exécution est la présence d'un réhaut 11 sous forme d'une bague en matière plastique ou métallique de profil globalement rectangulaire insérée entre le verre 3, le prolongement supérieur de l'insert 1 et le cadran 12. Ce réhaut joue le même rôle esthétique que dans une montre usuelle mais en plus il exerce une fonction très importante en relation avec le montage et l'assemblage de la montre. En effet, le cadran 12 ne possède pas de pied et n'est pas fixé, comme c'est usuellement le cas, sur la platine. Il est simplement posé sur la platine et retenu par le réhaut. Pour assurer cette fonction, l'insert 1 présente une goupille saillante 13 dans 1 ' epaulement supérieur du corps annulaire 6. Cette goupille peut être formée d'une pièce avec l'insert ou lui être liée lors du moulage. Dans ce cas, elle peut être en un matériau différent, par exemple en métal. La goupille 13 est située par exemple sur douze heures et dimensionnée de manière à assurer d'une part l'orientation du cadran 12, qui présentera une légère découpure à sa périphérie, engagée sur la goupille, et d'autre part la fixation du réhaut. Celui-ci présente en effet une forure à l'emplacement de douze heures, correspondant à la goupille. On se rend compte que cette disposition simplifie considérablement l'assemblage et le montage de la montre.Another feature found in all embodiments is the presence of a flange 11 in the form of a plastic or metallic ring of generally rectangular profile inserted between the glass 3, the upper extension of the insert 1 and the dial 12. This flange plays the same aesthetic role as in a usual watch but in addition it exerts a very important function in relation to the assembly and assembly of the watch. Indeed, the dial 12 has no base and is not fixed, as is usually the case, on the plate. It is simply placed on the plate and retained by the flange. To perform this function, the insert 1 has a protruding pin 13 in the upper shoulder of the annular body 6. This pin can be formed in one piece with the insert or be linked to it during molding. In this case, it can be made of a different material, for example metal. The pin 13 is located for example over twelve hours and dimensioned so as to ensure on the one hand the orientation of the dial 12, which will have a slight cutout at its periphery, engaged on the pin, and on the other hand the fixing of the flange . This one indeed presents a drill at the location of twelve hours, corresponding to the pin. We realize that this arrangement considerably simplifies the assembly and mounting of the watch.
Des tétons de centrage 20 du réhaut sont répartis le long de la base du prolongement tubulaire supérieur, du côté intérieur, afin de maintenir le réhaut centré et appuyé contre le cadran par la face inférieure du verre . Le corps annulaire 6 est équipé d'un tube de guidage 18 de la tige de commande du mouvement .Centering pins 20 of the flange are distributed along the base of the upper tubular extension, on the inner side, in order to keep the flange centered and pressed against the dial by the underside of the glass. The annular body 6 is equipped with a guide tube 18 of the movement control rod.
Ces détails sont représentés à la fig. 4 qui montre en plan l'insert 1 de la première forme d'exécution, avec le réhaut 11, la périphérie de la lunette inférieure 4 étant également visible. Le tube de guidage 18 sort d'une embase 19 de forme semi cylindrique. Il peut être moulé d'une pièce avec l'insert ou, comme la goupille 13, être rapporté. A propos de la goupille 13, on notera qu'elle peut présenter dans sa face supérieure, visible sous le verre, une marque caractéristique (par exemple croix suisse) .These details are shown in fig. 4 which shows in plan the insert 1 of the first embodiment, with the flange 11, the periphery of the lower window 4 also being visible. The guide tube 18 comes out of a base 19 of semi-cylindrical shape. It can be molded in one piece with the insert or, like the pin 13, be attached. Regarding the pin 13, it should be noted that it may have in its upper face, visible under the glass, a characteristic mark (for example Swiss cross).
Aux fig. 1 et 3 , ainsi que dans la quatrième forme d'exécution représentée par les fig. 6 à 9, la montre comporte une pièce supplémentaire : un brancard porte-cornes dont l'allure est reproduite en 14 à la fig. 5 ou en 15 aux fig. 8 et 9. La constitution et la fonction de cette pièce s'expliquent d'elles-mêmes. La face interne 24 du corps annulaire du brancard est engagée sur la face externe de l'insert 1. Un trou radial 16 et un logement semi cylindrique 17 correspondent au tube 18 et à l'embase semi cylindrique 19 de l'insert 1 (fig. 4).In fig. 1 and 3, as well as in the fourth embodiment represented by FIGS. 6 to 9, the watch has an additional part: a stretcher carrying horns, the appearance of which is reproduced in 14 in FIG. 5 or 15 in figs. 8 and 9. The constitution and function of this piece are self-explanatory. The internal face 24 of the annular body of the stretcher is engaged on the external face of the insert 1. A radial hole 16 and a semi-cylindrical housing 17 correspond to the tube 18 and to the semi-cylindrical base 19 of the insert 1 (fig. . 4).
Dans la forme d'exécution de la fig. 2, il n'y a pas de brancard. On voit que l'insert 1 présente ici une face externe cylindrique de même diamètre que les lunettes supérieure et inférieure 2 et 4. Sur six heures et douze heures, l'insert présente des logements 21 pour l'engagement des extrémités du bracelet et des forures 22 pour l'accrochage des barrettes. Autrement, les dispositions déjà décrites se retrouvent dans cette réalisation. Dans la montre terminée, la face latérale de l'insert sera visible, ce qui n'est pas le cas avec les autres formes d'exécution représentées.In the embodiment of FIG. 2, there is no stretcher. We see that the insert 1 here has a cylindrical outer face of the same diameter as the upper glasses and lower 2 and 4. Over six hours and twelve hours, the insert has housings 21 for engaging the ends of the bracelet and holes 22 for attaching the bars. Otherwise, the arrangements already described are found in this embodiment. In the finished watch, the side face of the insert will be visible, which is not the case with the other embodiments shown.
La forme d'exécution de la fig. 3 est très semblable à celle de la fig. 1 au point de vue de l'agencement des pièces. Elle se distingue par le fait que le verre 3 et la pastille de fond 5 sont plus épaisses et que l'engagement des prolongements tubulaires 9 et 10 entre les parties qui les compriment est plus fort. En outre, des vis 23 sont prévues pour assurer les liaisons entre lunettes et insert. De telles exécutions sont prévues spécialement pour des montres de grande robustesse, notamment des montres de plongée. Les essais ont montré que l' étanchéité peut être garantie jusqu'à 500 ou même 1000 m.The embodiment of fig. 3 is very similar to that of FIG. 1 in terms of the arrangement of the rooms. It is distinguished by the fact that the glass 3 and the bottom pad 5 are thicker and that the engagement of the tubular extensions 9 and 10 between the parts which compress them is stronger. In addition, screws 23 are provided to ensure the connections between glasses and insert. Such executions are specially provided for watches of great robustness, in particular diving watches. Tests have shown that water resistance can be guaranteed up to 500 or even 1000 m.
La quatrième forme d'exécution donnée à titre d'exemple montre que la construction de boîte selon l'invention peut se prêter à toutes les variétés de montres connues, y compris des montres de haut de gamme. A la fig. 6, on voit un insert 1 dont le prolongement tubulaire supérieur 9 a un contour rectangulaire, alors que le corps annulaire 6 et le prolongement tubulaire 10 (fig. 7) sont circulaires. Comme on le voit aux fig. 8 et 9a à 9c, la boîte est complétée par une lunette supérieure 2 et une lunette inférieure 4 qui jouent ensemble le rôle du brancard 15. La lunette supérieure s'engage sur le prolongement tubulaire supérieur 9 de manière à assujettir le verre comme dans les autres formes d'exécution. Le réhaut 11 a ici la forme d'une bague rectangulaire de limitation de la hauteur de l'aiguillage. La lunette inférieure 4 possède une ouverture circulaire 24 qui s'engage sur le prolongement tubulaire inférieur 10 de l'insert et assujettit une pastille de fond (non représentée) comme dans les autres formes d'exécution. Le bracelet 25 est un bracelet métallique à maillons articulés. Il peut bien entendu être remplacé par un bracelet en cuir.The fourth embodiment given by way of example shows that the case construction according to the invention can lend itself to all the varieties of known watches, including high-end watches. In fig. 6, an insert 1 can be seen, the upper tubular extension 9 of which has a rectangular outline, while the annular body 6 and the tubular extension 10 (fig. 7) are circular. As seen in Figs. 8 and 9a to 9c, the box is completed by an upper bezel 2 and a lower bezel 4 which together play the role of the stretcher 15. The upper bezel engages on the upper tubular extension 9 so as to secure the glass as in the other forms of execution. The flange 11 here has the shape of a rectangular ring for limiting the height of the switch. The lower window 4 has a circular opening 24 which engages on the lower tubular extension 10 of the insert and secures a bottom pad (not shown) as in the other embodiments. Bracelet 25 is a metal bracelet with articulated links. It can of course be replaced by a leather strap.
Les fig. 10a à 10c illustrent une variante dans laquelle la lunette inférieure est de forme ronde et ne participe pas à la fonction de brancard, qui est réalisée par la seule lunette supérieure .Figs. 10a to 10c illustrate a variant in which the lower window is of round shape and does not participate in the stretcher function, which is performed by the upper window only.
Comme représenté aux fig. 11 à 13, la lunette inférieure 4 pourrait aussi être d'une pièce avec la pastille de fond. D'autre part, les deux lunettes, supérieure 2 et inférieure 4, pourraient être munies de filetages intérieurs de façon à venir se fixer à vis sur les prolongements tubulaires de l'insert, ce qui permet d'obtenir encore une meilleure étanchéité. As shown in fig. 11 to 13, the lower bezel 4 could also be in one piece with the bottom pad. On the other hand, the two glasses, upper 2 and lower 4, could be provided with internal threads so as to be fixed with screws on the tubular extensions of the insert, which makes it possible to obtain even better sealing.
