Abstract

A waterproof watch case has a casing (1) with a groove (9) into which is fixed a glass (10). The casing is composed of an inner ring (2) made from a base metal or plastic, and an external ring (3) made from precious metal and which forms a cover over the inner ring. The inner ring has a shoulder (5) which fits into a groove (4) in the outer ring. The back of the watch is fixed in place by a screw (19) which screws into the inner ring, locking the movement in place and compressing the watertight joints (16a,16b). A further modification is to make the back out of two pieces, an exterior ring of precious metal with a glass or non-metallic plate inside it.

Description

La présente invention concerne une boîte de montre étanche, selon le préambule de la revendication 1.The present invention relates to a waterproof watch case, according to the preamble of claim 1.

Dans les montres connues, par exemple de EP-A-0 150 746 et de US-A-309 158, la carrure-lunette a pour fonction de positionner, dans la boîte, le cercle d'encageage qui, à son tour, positionne et immobilise le mouvement dans la boîte. Elle a, en plus, la fonction de recevoir les vis de fixation du fond et, finalement, les surfaces extérieures de la carrure-lunette constituent un élément important de l'aspect esthétique de la boîte. Vu ces fonctions et la stabilité requise ces carrure-lunettes doivent nécessairement être massives. Par conséquent, faites en métal précieux, elles sont forcément coûteuses.In known watches, for example from EP-A-0 150 746 and from US-A-309 158, the middle part of the bezel has the function of positioning, in the case, the casing circle which, in turn, positions and immobilizes the movement in the box. It has, in addition, the function of receiving the fixing screws of the base and, finally, the exterior surfaces of the middle part of the bezel constitute an important element of the aesthetic appearance of the case. Given these functions and the required stability, these glasses must necessarily be massive. Therefore, made of precious metal, they are necessarily expensive.

Or, les prescriptions sur les métaux précieux réglant la définition d'une boîte or (ou platine) prescrivent, pour un tel cas, que toutes les parties extérieures en métal, d'une telle boîte, soient en métal précieux.However, the prescriptions on precious metals regulating the definition of a gold box (or platinum) prescribe, for such a case, that all the external metal parts of such a box are made of precious metal.

La boîte de montre décrite dans EP-A-0 150 746 présente une carrure, désignée par bague extérieure dans ce document qui sert d'élément de protection et de décoration. Elle est formée d'une pièce massive en un matériau dur et reçoit concentriquement le cercle d'encageage qui est désigné par bague intérieure et qui reçoit aussi les vis de fixation du fond et de la plaque frontale formée de la glace et, dans certains exemples, de la glace et d'une lunette. Pour satisfaire aux prescriptions sur les métaux précieux mentionnées, ci-devant, la boîte de montre selon EP-A-0 150 746 devrait être munie d'une bague extérieure (carrure) et, dans certains exemples, en plus d'une lunette, réalisées entièrement en or pour pouvoir être désignée comme boîte or.The watch case described in EP-A-0 150 746 has a middle, designated by outer ring in this document which serves as a protective and decorative element. It is formed of a solid piece of hard material and concentrically receives the casing circle which is designated by inner ring and which also receives the fixing screws of the bottom and of the front plate formed of the glass and, in certain examples , ice and a telescope. To meet the requirements on precious metals mentioned above, the watch case according to EP-A-0 150 746 should be provided with an outer ring (middle) and, in some examples, in addition to a bezel, made entirely of gold so that they can be designated as a gold box.

Le problème qui est à la base de la présente invention est de réaliser une boîte de montre du type précité très plate, très légère et étanche par un système fiable et qui, en particulier, permet par rapport aux boîtes de l'état de la technique, une importante économie de métal précieux lorsqu'elle est confectionnée comme boîte or ou platine tout en respectant pleinement les prescriptions sur les métaux précieux concernant les boîtes de montres.The problem which is the basis of the present invention is to produce a watch case of the aforementioned type very flat, very light and waterproof by a reliable system and which, in particular, allows, compared with the boxes of the prior art , a significant saving of precious metal when it is made as a gold or platinum box while fully respecting the precious metal regulations concerning watch cases.

Ces buts sont réalisés par la boîte de montre étanche définie dans les revendications.These objects are achieved by the waterproof watch case defined in the claims.

On reconnaît que, grâce aux mesures prévues selon l'invention, la partie extérieure des deux parties dont est formée la carrure-lunette, donc l'enveloppe, n'a pratiquement pas de forces à absorber. Elle peut, par conséquent, être conçue avec un minimum de matière d'où résulte une économie importante de métal précieux pouvant aller jusqu'à 60 à 70% comparé aux constructions classiques monocoque connues jusqu'ici tout en gardant tous les avantages techniques d'une boîte à fond vissé, notamment l'accès facile, même à un non-professionel, pour le changement de pile lorsque la boîte reçoit un mouvement à quartz.It is recognized that, thanks to the measures provided for according to the invention, the outer part of the two parts of which the middle-bezel is formed, therefore the envelope, has practically no forces to absorb. It can therefore be designed with a minimum of material resulting in a significant saving of precious metal of up to 60 to 70% compared to conventional monocoque constructions known until now while retaining all the technical advantages of a screw-down case, including easy access, even to a non-professional, for changing the battery when the box receives a quartz movement.

Cette économie de métal précieux peut être poussée encore plus loin en choisissant la réalisation selon la revendication 2.This saving of precious metal can be taken even further by choosing the embodiment according to claim 2.

La forme de réalisation selon la revendication 6 permet de réduire encore l'épaisseur de la boîte de montre par rapport aux constructions connues avec joints d'étanchéité entreposés entre le fond et la carrure.The embodiment according to claim 6 makes it possible to further reduce the thickness of the watch case compared to known constructions with seals stored between the base and the middle part.

Des exemples de réalisation de l'invention sont décrits ci-après en se référant au dessin annexé, dans lequel:

  • La figure 1 est une vue partielle en coupe d'une première forme d'exécution d'une boîte de montre selon l'invention, et
  • la figure 2 est une coupe analogue à celle de la figure 1 d'une seconde forme d'exécution.
Examples of embodiments of the invention are described below with reference to the appended drawing, in which:
  • FIG. 1 is a partial sectional view of a first embodiment of a watch case according to the invention, and
  • Figure 2 is a section similar to that of Figure 1 of a second embodiment.

La boîte de montre étanche selon chacun des deux exemples de réalisation représentés sur le dessin comporte une carrure-lunette désignées dans son ensemble par la référence 1. Cette carrure-lunette 1 se compose de deux pièces annulaires concentriques 2 et 3 emboîtées l'une dans l'autre à engagement par friction. La partie intérieure de ces deux pièces est un anneau rigide 2 qui peut être en métal commun ou en plastique. Par contre la partie extérieure des deux parties composant la carrure-lunette 1 est en métal précieux, par exemple en or ou en platine, et forme une enveloppe 3 recouvrant la périphérie de l'anneau rigide 2.The waterproof watch case according to each of the two exemplary embodiments represented in the drawing comprises a middle part of the bezel designated as a whole by the reference 1. This middle part of the bezel 1 consists of two concentric annular parts 2 and 3 fitted one into the the other with friction engagement. The inner part of these two parts is a rigid ring 2 which can be made of common metal or plastic. On the other hand, the outer part of the two parts making up the middle part of the bezel 1 is made of precious metal, for example gold or platinum, and forms an envelope 3 covering the periphery of the rigid ring 2.

L'enveloppe 3 en métal précieux est formée sur sa face intérieure avec un cran 4 sur lequel repose la face inférieure d'un épaulement 5 de l'anneau rigide 2 de façon à empêcher ce dernier de glisser axialement vers le bas dans l'enveloppe 3. Dans la position emboîtée correcte des pièces 2 et 3 telle que représentée au dessin les faces inférieures 6 de l'anneau rigide 2 et 7 de l'enveloppe 3, qui sont planes, sont dans un même plan et servent d'appui au fond 8 de la boîte de montre ainsi qu'on le verra plus loin.The casing 3 of precious metal is formed on its inner face with a notch 4 on which the underside of a shoulder 5 of the rigid ring 2 rests so as to prevent the latter from sliding axially downward in the casing 3. In the correct nested position of parts 2 and 3 as shown in the drawing, the lower faces 6 of the rigid ring 2 and 7 of the casing 3, which are planar, are in the same plane and serve to support the bottom 8 of the watch case as will be seen later.

Un second cran 9 est formé à l'extrémité supérieure de l'enveloppe 3 pour recevoir la glace 10 qui y est collée de façon à obturer de façon étanche l'ouverture supérieure de la carrure-lunette 1 tout en augmentant la rigidité de l'ensemble glace/enveloppe. Il va de soi que l'anneau rigide 2 est inséré dans l'enveloppe 3 avant la fixation de la glace 10 donnant ainsi à l'enveloppe 3 la rigidité nécessaire pour permettre le collage de la glace 10. Du fait de la présence du cran 4 et de l'épaulement 5, l'insertion de l'anneau rigide 2 ne peut se faire que depuis l'ouverture supérieure de l'enveloppe 3.A second notch 9 is formed at the upper end of the casing 3 to receive the glass 10 which is stuck thereon so as to seal the upper opening of the middle part-bezel 1 while increasing the rigidity of the glass / envelope assembly. It goes without saying that the rigid ring 2 is inserted in the casing 3 before the fixing of the glass 10, thus giving the casing 3 the rigidity necessary to allow the gluing of the glass 10. Due to the presence of the notch 4 and from shoulder 5, insertion of the rigid ring 2 can only be done from the upper opening of the envelope 3.

La surface supérieure 11 de l'anneau rigide 2, qui est visible à travers la glace 10, peut être décorée, par exemple par un dépôt métallique où elle peut être cachée.The upper surface 11 of the rigid ring 2, which is visible through the glass 10, can be decorated, for example by a metal deposit where it can be hidden.

Dans l'exemple de la figure 1 cette partie de l'anneau rigide 2 visible à travers la glace 10 est cachée par un anneau 12 décoratif ou conçu comme tour d'heures et placé dans un logement approprié de la carrure-lunette 1. Dans l'exemple de la figure 2 cet anneau rigide, désigné ici par 12a, est collé à la face inférieure de la glace 10 ou venu d'une pièce avec elle. Il peut être en saphir, céramique ou alors en métal précieux.In the example of FIG. 1, this part of the rigid ring 2 visible through the glass 10 is hidden by a decorative ring 12 or designed as an hour wheel and placed in an appropriate housing of the middle part. the example of Figure 2 this rigid ring, designated here by 12a, is glued to the underside of the glass 10 or come in one piece with it. It can be made of sapphire, ceramic or precious metal.

A ce point du montage le mouvement 13 muni du cadran 14 peut être placé dans la boîte par l'ouverture inférieure de la carrure-lunette 1. Le mouvement 13,14 est positionné dans la boîte de manière connue à l'aide d'un cercle d'encageage 15.At this point in the assembly, the movement 13 fitted with the dial 14 can be placed in the box through the lower opening of the middle part-bezel 1. The movement 13, 14 is positioned in the box in a known manner using a casing ring 15.

Avant que la boîte soit fermée par l'application du fond 8 il y a lieu de mettre en place le ou les joints d'étanchéité. Dans les deux exemples illustrés deux joints d'étanchéité sont prévus sous forme d'anneaux 16a et 16b, de diamètre différent. L'un de ces anneaux, celui désigné par 16a, est placé de façon à dépasser légèrement de la face inférieure 6,7 de la carrure-lunette, dans un logement formé entre la surface périphérique de l'anneau rigide 2 et un biais 17 de la face intérieure de l'enveloppe 3. Le second joint d'étanchéité, désigné par 16b est placé autour d'une nervure 18 du fond 8.Before the box is closed by the application of the bottom 8, it is necessary to set up the seal (s). In the two examples illustrated two seals are provided in the form of rings 16a and 16b, of different diameter. One of these rings, the one designated by 16a, is placed so as to protrude slightly from the lower face 6.7 of the middle part, in a housing formed between the peripheral surface of the rigid ring 2 and a bias 17 of the inner face of the casing 3. The second seal, designated by 16b is placed around a rib 18 at the bottom 8.

Les joints d'étanchéité 16a,16b mis en place on peut procéder à la fermeture de la boîte par l'application du fond 8 dont le diamètre est tel qu'il excède le diamètre de l'ouverture intérieure de l'enveloppe 3.The seals 16a, 16b put in place, the box can be closed by applying the bottom 8, the diameter of which is such that it exceeds the diameter of the interior opening of the envelope 3.

La fixation du fond 8 à la carrure-lunette 1 se fait à l'aide de vis de fixation 19, vissées dans des taraudages 20 travaillés dans l'anneau rigide 2. Le serrage de ces vis de fixation 19 provoque le blocage du cercle d'encageage 15 par l'action d'une surface du fond contre une partie, ici une nervure 22, du cercle d'encageage 15 qui applique le cadran 10 contre un appui 21 de l'anneau rigide 2.The bottom 8 is fixed to the middle part of the bezel 1 using fixing screws 19, screwed into threads 20 worked in the rigid ring 2. Tightening these fixing screws 19 causes the circle d to be blocked. casing 15 by the action of a bottom surface against a part, here a rib 22, of the casing circle 15 which applies the dial 10 against a support 21 of the rigid ring 2.

Simultanément le serrage des vis de fixation 19 applique la face supérieure du bord extérieure du fond 8 contre les surfaces inférieures 6 et 7 de l'anneau rigide 2 et de l'enveloppe 3 respectivement en comprimant en même temps les joints d'étanchéité 16a,16b le joint d'étanchéité 16b s'écrasant dans un espace formé par un biais 23 de l'anneau rigide 2 semblable au biais 17 de l'enveloppe 3.Simultaneously the tightening of the fixing screws 19 applies the upper face of the outer edge of the bottom 8 against the lower surfaces 6 and 7 of the rigid ring 2 and of the casing 3 respectively by simultaneously compressing the seals 16a, 16b the seal 16b is crushed in a space formed by a bias 23 of the rigid ring 2 similar to the bias 17 of the casing 3.

On constatera que l'agencement prévu pour les joints d'étanchéité 16a et 16b dans des logements en retrait par rapport aux surfaces 6 et 7 contre lesquelles le fond 8 est appliqué permet de réduire encore l'épaisseur de la boîte décrite.It will be seen that the arrangement provided for the joints sealing 16a and 16b in recesses recessed with respect to surfaces 6 and 7 against which the bottom 8 is applied makes it possible to further reduce the thickness of the box described.

L'enveloppe 3 peut encore être allégée en prévoyant dans sa surface intérieure, des évidements 24 ce qui permet de réaliser une économie de poids et de métal précieux additionelle sans que l'aspect extérieure de la boîte de montre en soit affecté.The casing 3 can be further lightened by providing in its internal surface, recesses 24 which makes it possible to save additional weight and precious metal without affecting the external appearance of the watch case.

Un autre moyen de réaliser une économie de métal précieux tout en respectant les préscriptions sur les métaux précieux consisterait à remplacer un fond 8 entièrement en métal précieux par un fond qui, comme cela est représenté dans l'exemple de la figure 1, est formé de deux pièces à savoir d'un anneau extérieur 25 en métal précieux dans l'ouverture duquel est collé une plaque 26 en verre ou autre matière non-métallique.Another way of saving precious metal while respecting the prescriptions for precious metals would be to replace a bottom 8 made entirely of precious metal by a bottom which, as shown in the example in FIG. 1, is formed from two pieces, namely an outer ring 25 of precious metal in the opening of which is bonded a plate 26 of glass or other non-metallic material.
