Description

La présente invention est relative à une boîte de montre du type dans lequel la glace est fixée dans une lunette ou réhaut par l'intermédiaire d'un joint d'étanchéité, cette lunette ou ce réhaut étant rapporté à la carrure de la boîte par des moyens de fixation à vis.The present invention relates to a watch case of the type in which the crystal is fixed in a bezel or flange by means of a seal, this bezel or this flange being attached to the middle of the box by screw fixing means.

Dans une construction de boîte de montre de ce genre connue du brevet CH 621 908, le réhaut est fixé à la carrure non seulement par des moyens a vis mais également par une saillie du réhaut qui vient se crocheter dans un évidement de la carrure se trouvant du côté de la glace opposé à celui où sont prévus les moyens de fixation à vis. Cette disposition a l'avantage de permettre un montage rapide du réhaut sur la carrure, tout en garantissant une bonne étanchéité de l'ensemble. En outre, cette construction permet de réaliser des boîtes ayant des formes très diverses allant de la forme ronde classique à une forme asymétrique.In a watch case construction of this kind known from patent CH 621 908, the flange is fixed to the middle not only by screw means but also by a projection of the flange which is hooked in a recess in the middle being on the side of the glass opposite to that where the screw fixing means are provided. This arrangement has the advantage of allowing rapid assembly of the flange on the middle, while ensuring a good seal of the assembly. In addition, this construction makes it possible to produce boxes having very diverse shapes ranging from the classic round shape to an asymmetrical shape.

Quant au fond de cette boîte, il est monté à pression sur la carrure au moyen d'un système de crantage.As for the bottom of this box, it is press fitted to the middle by means of a notching system.

La présente invention a pour but de fournir une boîte de montre utilisant une disposition semblable à celle décrite dans le brevet précité, mais permettant de fixer avantageusement à la carrure par vissage, non seulement le réhaut, mais également le fond.The present invention aims to provide a watch case using an arrangement similar to that described in the aforementioned patent, but allowing advantageously to attach to the middle by screwing, not only the flange, but also the bottom.

Elle a donc pour objet une boîte de montre comportant une carrure, une glace montée dans un réhaut qui est rapporté à ladite carrure par une pluralité de premiers moyens de fixation à vis, et un fond rapporté également à ladite carrure, ladite boîte étant caractérisée en ce que ledit fond est rapporté à ladite carrure par une pluralité de seconds moyens de fixation à vis, chaque couple de premiers moyens de fixation et de seconds moyens de fixation ayant un axe commun, et en ce que chacun desdits couples de premiers et de seconds moyens de fixation comprennent un unique passage étagé centré sur ledit axe commun.It therefore relates to a watch case comprising a middle part, a crystal mounted in a flange which is attached to said middle part by a plurality of first screw fixing means, and a bottom also attached to said middle part, said case being characterized by that said base is attached to said middle by a plurality of second screw fixing means, each pair of first fixing means and second fixing means having a common axis, and in that each of said pairs of first and second fixing means comprise a single stepped passage centered on said common axis.

Grâce à ces caractéristiques, il est possible de fabriquer la boîte, et en particulier sa carrure, moyennant un faible coût, car pour préparer la carrure, il suffira de ne percer qu'un seul passage au moyen d'un outil de perçage étagé, puis de fileter la partie du passage qui va recevoir la vis appartenant aux moyens de fixation ayant le diamètre le plus grand. Ainsi, les vis des moyens de fixation peuvent être mises en place l'une après l'autre dans le passage pendant l'assemblage de la boîte.Thanks to these characteristics, it is possible to manufacture the case, and in particular its middle part, at a low cost, because to prepare the middle part, it will suffice to pierce only one passage by means of a stepped drilling tool, then to thread the part of the passage which will receive the screw belonging to the fixing means having the largest diameter. Thus, the screws of the fixing means can be placed one after the other in the passage during the assembly of the box.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés sur lesquels :

  • les figures 1 et 3 montrent par des vues en coupe partielles, deux modes de réalisation de l'invention; et
  • la figure 2 montre un détail de la boîte de montre avant son assemblage définitif.
Other characteristics and advantages of the invention will appear during the description which follows, given solely by way of example and made with reference to the appended drawings in which:
  • Figures 1 and 3 show by partial sectional views, two embodiments of the invention; and
  • Figure 2 shows a detail of the watch case before its final assembly.

En se référant d'abord aux figures 1 et 2, on voit que la boîte de montre selon le premier mode de réalisation de l'invention comporte une carrure 1 composée d'une bague extérieure d'enjoliveur 2 et d'une bague intérieure de renfort 3. La bague d'enjoliveur 2 comprend une partie périphérique 2a et un voile central 2b qui sert de préférence comme cadran de la montre, ainsi qu'une cavité intérieure 2c dans laquelle est reçue la bague de renfort 3. La bague d'enjoliveur 2 peut être faite en toute matière appropriée, mais avantageusement elle peut être réalisée en bois ou en une matière minérale telle que de la pierre, par exemple.Referring first to Figures 1 and 2, it can be seen that the watch case according to the first embodiment of the invention comprises a middle part 1 composed of an outer ring of hubcap 2 and an inner ring of reinforcement 3. The hubcap ring 2 comprises a peripheral part 2a and a central veil 2b which preferably serves as the dial of the watch, as well as an interior cavity 2c in which the reinforcement ring 3 is received. hubcap 2 can be made of any suitable material, but advantageously it can be made of wood or a mineral material such as stone, for example.

La bague de renfort 3 est également formée d'une partie périphérique 3a et d'un voile central 3b et elle s'ajuste dans la cavité 2c de la bague d'enjoliveur 2 où elle peut être maintenue en place par un joint de colle 4. Elle comporte à son tour une cavité interne 3c destinée à loger le mouvement 5 de la montre. Celui-ci est maintenu en place par un cercle d'encageage 6, comme cela est classique.The reinforcing ring 3 is also formed of a peripheral part 3a and of a central veil 3b and it fits in the cavity 2c of the hubcap ring 2 where it can be held in place by an adhesive joint 4 It in turn comprises an internal cavity 3c intended for house movement 5 of the watch. This is held in place by a casing circle 6, as is conventional.

Du côté de la face du voile 2b opposée à la cavité 2c de la bague 2, celle-ci présente une cavité supérieure 7 dans laquelle vient s'ajuster un réhaut 8. Celui-ci présente un épaulement 9 contre lequel vient s'appuyer une glace 10 qui est maintenue dans le réhaut au moyen d'une garniture d'étanchéité 11. On remarquera que la surface supérieure 12 de la bague 2 se raccorde à fleur à la surface supérieure 13 du réhaut 9 d'où la glace 10 fait légèrement saillie vers le haut.On the side of the face of the web 2b opposite the cavity 2c of the ring 2, the latter has an upper cavity 7 in which a flange 8 is fitted. The latter has a shoulder 9 against which a glass 10 which is held in the flange by means of a seal 11. It will be noted that the upper surface 12 of the ring 2 is flush with the upper surface 13 of the flange 9 from which the glass 10 is slightly protruding upwards.

A sa face inférieure, le réhaut 9 présente une rainure périphérique 14 destinée à loger un joint d'étanchéité 15 qui est comprimé contre le voile 2b lors de l'assemblage de la boîte.On its underside, the flange 9 has a peripheral groove 14 intended to accommodate a seal 15 which is compressed against the web 2b during assembly of the box.

De même, la bague de renfort 3 comporte une rainure 16 pour loger un joint d'étanchéité 17 qui est comprimé par un fond vissé 18 au montage de la boîte.Likewise, the reinforcing ring 3 has a groove 16 for housing a seal 17 which is compressed by a screwed bottom 18 when the box is mounted.

On notera que dans le présent mode de réalisation, le fond 18 comporte des pattes de fixation 19 pour permettre d'attacher un bracelet 20 à la boîte.It will be noted that in this embodiment, the bottom 18 has fixing lugs 19 to allow a strap 20 to be attached to the box.

Selon l'invention, la boîte comporte plusieurs ensembles d'assemblage à vis 21 permettant de maintenir ensemble toutes les pièces constitutives de la boîte que l'on vient de décrire.According to the invention, the box comprises several assembly assemblies with screws 21 making it possible to hold together all the constituent parts of the box which have just been described.

Ces ensembles d'assemblage, qui sont de préférence au nombre de quatre ou six répartis convenablement selon la périphérie de la boîte, ne définissent chacun qu'un seul axe X-X parallèle à l'axe central de la montre (non visible sur les figures). Chaque ensemble comporte un passage étagé 22 composé, en partant du fond 18 vers le haut (voir figure 2) :

  • d'un trou 23 à entrée cylindrico-conique 24 pratiqué dans le fond 18;
  • d'un trou 25 pratiqué dans la bague de renfort 3 et ayant une première partie 25a, filetée avec un diamètre de taraudage d1, une seconde partie 25b de diamètre d2 plus petit que le diamètre d1, et une partie de raccordement conico-cylindrique 25c définissant un épaulement radial d'appui 26;
  • d'un trou 27, de diamètre d3, pratiqué dans le voile 1b de la carrure 1; et
  • d'un trou borgne 28, fileté avec un diamètre de taraudage d4, ménagé dans le réhaut 9.
These assembly assemblies, which are preferably four or six in number distributed suitably along the periphery of the case, each define only one axis XX parallel to the central axis of the watch (not visible in the figures) . Each assembly comprises a stepped passage 22 made up, starting from the bottom 18 upwards (see FIG. 2):
  • a hole 23 with cylindrical-conical entry 24 made in the bottom 18;
  • a hole 25 made in the reinforcement ring 3 and having a first part 25a, threaded with a diameter tapping d1, a second part 25b of diameter d2 smaller than the diameter d1, and a conical-cylindrical connection part 25c defining a radial support shoulder 26;
  • a hole 27, of diameter d3, made in the web 1b of the middle part 1; and
  • a blind hole 28, threaded with a tapping diameter d4, formed in the flange 9.

Dans le présent mode de réalisation, le passage 22 se rétrécit du fond 18 vers le réhaut 8, avec d1>d2>d4. Le diamètre d3 du trou 27 peut être légèrement plus grand que le diamètre d2.In the present embodiment, the passage 22 narrows from the bottom 18 to the flange 8, with d1> d2> d4. The diameter d3 of the hole 27 may be slightly larger than the diameter d2.

Chaque ensemble d'assemblage comporte en outre une première vis 29 de diamètre dl destinée à fixer le fond 18 sur la bague 16, ainsi qu'une deuxième vis 30 de diamètre d4 pour la fixation du réhaut 8 sur les bagues 2 et 3. La tête de la vis 30 est en appui contre l'épaulement 26 de la partie de raccordement 25c.Each assembly assembly further comprises a first screw 29 of diameter dl intended to fix the bottom 18 on the ring 16, as well as a second screw 30 of diameter d4 for fixing the flange 8 on the rings 2 and 3. The head of the screw 30 bears against the shoulder 26 of the connection part 25c.

La description qui précède illustre les avantages que procure l'invention. En effet, étant donné que les vis de fixation 29 et 30, respectivement pour l'assemblage du fond 18 à la bague 3 et pour celui de la bague 3 au réhaut 9, sont alignées sur le même axe X-X, il est possible de préparer la bague 3 en seulement deux passes, l'une pour percer le trou 25 à l'aide d'un outil de perçage ayant un profil extérieur complémentaire à la forme du trou 25, et l'autre pour fileter, à l'aide d'un taraud approprié, la partie 25a de ce trou. Le temps de fabrication et par conséquent le coût de la boîte s'en trouvent réduits. En outre, du fait que le fond 18 est rapporté par vissage sur la bague de renfort 3, ce mode de réalisation permet de fixer un bracelet 20 au fond 18, ce qui permet d'obtenir des effets esthétiques particuliers. Enfin, l'étanchéité de la boîte est parfaitement garantie.The foregoing description illustrates the advantages of the invention. Indeed, since the fixing screws 29 and 30, respectively for the assembly of the bottom 18 to the ring 3 and for that of the ring 3 to the flange 9, are aligned on the same axis XX, it is possible to prepare the ring 3 in just two passes, one for drilling the hole 25 using a drilling tool having an external profile complementary to the shape of the hole 25, and the other for threading, using 'a suitable tap, part 25a of this hole. The manufacturing time and therefore the cost of the box are reduced. In addition, because the bottom 18 is attached by screwing onto the reinforcing ring 3, this embodiment makes it possible to attach a bracelet 20 to the bottom 18, which makes it possible to obtain particular aesthetic effects. Finally, the watertightness of the box is perfectly guaranteed.

Selon une variante de l'invention qui n'a pas été représentée aux dessins, il est possible de faire déboucher la partie de grand diamètre du passage 22 au niveau de la surface 13 du réhaut 8 et de prévoir un trou borgne dans le fond 18. Cette variante revient donc à inverser l'ensemble de fixation à vis, dont la vis sera apparente à la surface supérieure de la boîte. Ceci permet l'obtention d'effets esthétiques particuliers, tout en conservant les avantages de simplicité de fabrication et faible coût qu'apporte l'invention.According to a variant of the invention which has not been shown in the drawings, it is possible to unblock the large diameter part of the passage 22 at level of the surface 13 of the flange 8 and of providing a blind hole in the bottom 18. This variant therefore amounts to inverting the screw fixing assembly, the screw of which will be visible on the upper surface of the box. This allows obtaining specific aesthetic effects, while retaining the advantages of simplicity of manufacture and low cost that the invention brings.

La figure 3 montre un autre mode de réalisation dans lequel, par rapport au mode de réalisation des figures 1 et 2, la bague d'enjoliveur 1 et la bague de renfort 3 ont été remplacées par une carrure unique 31 dans laquelle est percé la partie correspondante de l'unique passage étagé 22. Dans ce cas, un cadran 32 est monté sur la carrure 31 et pris entre le réhaut 8 et un épaulement radial 33 de la carrure 31. Par ailleurs, la carrure 31 ne comporte plus qu'un seul trou 34 de diamètre d3 qui peut être percé en même temps que le trou 25, la partie 25b de diamètre d2 présente dans le mode de réalisation des figures 1 et 2, n'étant pas nécessaire dans celui de la figure 3.Figure 3 shows another embodiment in which, relative to the embodiment of Figures 1 and 2, the trim ring 1 and the reinforcement ring 3 have been replaced by a single middle 31 in which is pierced the part corresponding to the single stepped passage 22. In this case, a dial 32 is mounted on the middle part 31 and taken between the flange 8 and a radial shoulder 33 of the middle part 31. Furthermore, the middle part 31 has only one single hole 34 of diameter d3 which can be drilled at the same time as the hole 25, the part 25b of diameter d2 present in the embodiment of FIGS. 1 and 2, not being necessary in that of FIG. 3.
