Description

La présente invention est relative à une boîte de montre pour montage automatisé selon le préambule de la revendication 1 et comportant une carrure, un cadre d'encageage emboîté dans la carrure, ledit cadre étant fait en matière solide, déformable élastiquement, un fond, une lunette et une glace fixée de façon étanche à la lunette pour définir un espace intérieur dans lequel est confiné un mouvement et un cadran sur lequel se déplacent des aiguilles d'affichage du temps.The present invention relates to a watch case for automated mounting according to the preamble of claim 1 and comprising a middle part, a casing frame fitted into the middle part, said frame being made of solid material, elastically deformable, a bottom, a bezel and a glass tightly fixed to the bezel to define an interior space in which a movement is confined and a dial on which time display hands move.

Un cadre d'encageage fait en matière solide, déformable élastiquement et servant non seulement de cadre d'adaptation du mouvement dans la boite, mais encore de moyens pour rendre cette boîte étanche a été proposé par exemple dans le brevet CH-A-319 293 et la demande de modèle d'utilité JP-U-22693/76, ainsi que dans la demande FR-A-2 017 168.A casing frame made of solid material, elastically deformable and serving not only as a framework for adapting movement in the box, but also as means for making this box waterproof has been proposed for example in patent CH-A-319,293 and application for utility model JP-U-22693/76, as well as in application FR-A-2 017 168.

Ces documents n'apportent cependant qu'une solution très partielle au problème que se propose de résoudre la présente invention. Notamment le cadre d'encageage montré dans ces documents n'est utilisé que pour assurer l'étanchéité du fond ou de la glace mais pas des deux simultanément. De même, le cadre d'encageage décrit dans les mêmes documents, n'a pas pour but, comme c'est le cas dans la présente invention, d'assurer d'un seul coup toutes les fonctions de l'emboîtage, à savoir la fixation étanche d'une lunette et d'un fond en même temps que la fixation et le positionnement du mouvement et du cadran à l'intérieur de la boite, cette construction permettant de surcroît un montage automatisé de toute la montre.These documents however provide only a very partial solution to the problem which the present invention proposes to solve. In particular the casing frame shown in these documents is only used to seal the bottom or the glass but not both simultaneously. Similarly, the casing frame described in the same documents, is not intended, as is the case in the present invention, to provide all of the functions of the casing, namely the waterproof fixing of a bezel and a case back at the same time as the fixing and positioning of the movement and of the dial inside the case, this construction also allowing automated assembly of the entire watch.

Pour ce faire, la boîte de montre selon l'invention comprend les caractéristiques techniques figurant dans la partie caractérisante de la revendication 1.To do this, the watch case according to the invention comprises the technical characteristics appearing in the characterizing part of claim 1.

L'invention sera comprise maintenant à la lecture de la description qui suit, description donnée à titre d'exemple et illustrée par le dessin dans lequel:

  • - la figure 1 est une coupe à 9 heures dans la boîte de montre selon un premier mode d'exécution de l'invention;
  • - la figure 1a est une coupe à 3 heures dans la boîte de montre représentée en figure 1;
  • - la figure 2 présente une coupe à 9 heures selon un deuxième mode d'exécution de l'invention; et
  • - la figure 3 montre une coupe à 9 heures selon un troisième mode d'exécution de l'invention.
The invention will now be understood on reading the description which follows, description given by way of example and illustrated by the drawing in which:
  • - Figure 1 is a section at 9 o'clock in the watch case according to a first embodiment of the invention;
  • - Figure 1a is a section at 3 o'clock in the watch case shown in Figure 1;
  • - Figure 2 shows a section at 9 o'clock according to a second embodiment of the invention; and
  • - Figure 3 shows a section at 9 o'clock according to a third embodiment of the invention.

La boîte de montre présentée en coupe aux figure 1, 2 et 3 fait apparaître une carrure 1, un cadre d'en- cageage 2 emboîté dans la carrure, un fond 3, une lunette 4 et une glace 5. Ces éléments définissent un espace intérieur fermé qui contient un mouvement 6 surmonté par un cadran 7 et des aiguilles 8. La carrure 1 peut être ronde ou de forme. Dans le premier cas, le cadre 2 sera rond avec une ouverture centrale ronde également. Dans le second cas, le cadre 2 sera de forme et son ouverture centrale sera ronde de préférence pour recevoir le mouvement 6, lui aussi généralement de forme ronde.The watch case presented in section in FIGS. 1, 2 and 3 shows a middle part 1, a casing frame 2 fitted into the middle part, a base 3, a bezel 4 and a crystal 5. These elements define a space closed interior which contains a movement 6 surmounted by a dial 7 and hands 8. The middle 1 can be round or of shape. In the first case, the frame 2 will be round with a round central opening also. In the second case, the frame 2 will have a shape and its central opening will preferably be round to receive movement 6, which is also generally round in shape.

La carrure 1 peut être en métal, acier ou zamac par exemple, ou en matière plastique dure. On choisira pour réaliser le cadre d'encageage 2 une matière plastique solide pour assurer une bonne tenue du mouvement 6, cette matière étant en même temps suffisamment élastique pour remplir les fonctions d'étanchéité qui apparaîtront par la suite. La lunette 4 comporte un logement annulaire ou de forme dans lequel est engagée et collée la glace 5, elle-même ronde ou de forme, respectivement.The middle part 1 can be made of metal, steel or zamak for example, or of hard plastic. To make the casing frame 2, a solid plastic material will be chosen to ensure good resistance of the movement 6, this material being at the same time sufficiently elastic to fulfill the sealing functions which will appear subsequently. The bezel 4 has an annular or shaped housing in which is engaged and glued the crystal 5, itself round or shaped, respectively.

La carrure 1 comporte une face intérieure présentant une première paroi verticale 9 et une seconde paroi verticale 10. Ces première et seconde parois sont reliées par un épaulement 11 lequel définit, dans la face intérieure de la carrure, un dégagement 12 qui s'étend, à partir de l'épaulement 11, jusqu'au haut de la carrure 1.The middle part 1 has an inner face having a first vertical wall 9 and a second vertical wall 10. These first and second walls are connected by a shoulder 11 which defines, in the inner face of the middle part, a clearance 12 which extends, from the shoulder 11, to the top of the middle part 1.

Le cadre d'encageage 2 s'étend quant à lui sur toute la hauteur de la carrure 1 et les figures montrent qu'il présente une face extérieure conformée pour épouser la forme de la face intérieure de la carrure, de manière à ce que le cadre 2 puisse être emboîté et positionné axialement avec précision par rapport à la carrure. Pour ce faire, le cadre 2 comporte un rebord 13 qui vient s'appuyer sur l'épaulement 11 de la carrure quand ce cadre est en place.The casing frame 2 extends over the entire height of the middle part 1 and the figures show that it has an outer face shaped to conform to the shape of the inner face of the middle part, so that the frame 2 can be fitted and positioned axially with precision with respect to the middle part. To do this, the frame 2 has a rim 13 which bears on the shoulder 11 of the middle when this frame is in place.

La partie interne du cadre d'encageage 2 comporte quatre logements remplissant des fonctions bien précises qui vont être décrites maintenant.The internal part of the casing frame 2 comprises four housings fulfilling very specific functions which will now be described.

Le cadre 2 présente un premier logement 14 dans lequel est engagée la lunette 4. Ce logement 14, en plus qu'il assure le centrage de la lunette par rapport à la carrure, assure l'étanchéité de la boite, pour sa partie lunette-carrure, par compression contre la carrure de la matière référencée 15 dont est fait le cadre 2. Le cadre 2 présente ensuite un deuxième logement 16 dans lequel est engagé le cadran 7. Les figures montrent que ce cadran est maintenu en place par un surplomb 17 présenté par la lunette 4. Ce cadran, qui n'est pas attaché au mouvement au moyen de pieds par exemple, peut être positionné angulaire- ment par un ergot solidaire du cadre et logé dans une encoche découpée dans le cadran. Le cadre 2 comporte encore un troisième logement 18 dans lequel repose un filet 19 faisant partie du mouvement 6. Grâce à cette disposition, le mouvement est tenu en place axialement puisque d'une part son filet s'appuie sur le logement 18 et d'autre part sa face supérieure est retenue par le cadran 7, lui-même retenu par le surplomb 17 de la lunette 4. Le cadre 2 présente enfin un quatrième logement 20 dans lequel est engagée une collerette 21 faisant partie du fond 3. Quand on applique le fond 3, la collerette 21 vient comprimer contre la carrure 1 la portion de matière 22 dont est fait le cadre 2, assurant ainsi l'étanchéité de la boîte pour sa partie fond-carrure.The frame 2 has a first housing 14 in which the bezel 4 is engaged. This housing 14, in addition to ensuring the centering of the bezel relative to the middle part, seals the case, for its part bezel- middle part, by compression against the middle part of the material referenced 15 which is the frame 2. The frame 2 then has a second housing 16 in which is engaged the dial 7. The figures show that this dial is held in place by an overhang 17 presented by bezel 4. This dial, which is not attached to the movement by means of feet for example, can be positioned angularly by a lug secured to the frame and housed in a notch cut out from the dial. The frame 2 also comprises a third housing 18 in which a net 19 which forms part of the movement 6 rests. Thanks to this arrangement, the movement is held in place axially since on the one hand its net rests on the housing 18 and on the other hand its upper face is retained by the dial 7, itself retained by the overhang 17 of the bezel 4. The frame 2 finally has a fourth housing 20 in which is engaged a flange 21 forming part of the bottom 3. When applying the bottom 3, the flange 21 compresses against the middle part 1 the portion of material 22 of which the frame 2 is made, thus ensuring the tightness of the case for its bottom-middle part.

Les explications qui viennent d'être données s'appliquent indifféremment aux divers modes d'exécution présentés par les figures 1, 2 et 3. Ces figures diffèrent l'une de l'autre d'abord par le type de mouvement 6 utilisé (calibre), ensuite par divers détails qui vont être passés en revue maintenant.The explanations which have just been given apply equally to the various embodiments presented by FIGS. 1, 2 and 3. These figures differ from one another first by the type of movement 6 used (caliber ), then by various details which will be reviewed now.

La figure 1 montre une construction utilisant un mouvement électronique 6 dont la hauteur est de 3 mm., ce qui donne pour la hauteur totale de la montre une valeur de 8,80 mm., compte-tenu de l'encombrement de la pile 28. Dans ce modèle le bas de lunette 4 est rectiligne, comme est rectiligne la partie horizontale du logement 14 sur laquelle repose la lunette. La partie apparente de la lunette 4 présente un simple arrondi 29.Figure 1 shows a construction using an electronic movement 6 whose height is 3 mm., Which gives for the total height of the watch a value of 8.80 mm., Taking into account the size of the battery 28 In this model, the bottom of the bezel 4 is rectilinear, as is the rectilinear part of the horizontal part of the housing 14 on which the bezel rests. The visible part of the bezel 4 has a simple rounded 29.

La figure 2 montre une construction utilisant un mouvement électronique dont la hauteur est de 2,50 mm., ce qui donne, compte-tenu de la pile 28 utilisée, une hauteur totale de la montre de 7,20 mm. Dans ce modèle, le bas de la lunette 4 présente une saillie 27 introduite dans le logement 14 du cadre 2, le bas de ce logement 14 se trouvant au même niveau que le bas du logement 16 recevant le cadran 7. Si la saillie n'existait pas, la portion de matière 15 ne serait pas suffisamment haute pour assurer une bonne étanchéité. La figure 2 présente le même arrondi 29 qu'en figure 1.Figure 2 shows a construction using an electronic movement whose height is 2.50 mm., Which gives, taking into account the battery 28 used, a total height of the watch of 7.20 mm. In this model, the bottom of the bezel 4 has a projection 27 introduced into the housing 14 of the frame 2, the bottom of this housing 14 being at the same level as the bottom of the housing 16 receiving the dial 7. If the projection does not did not exist, the portion of material 15 would not be high enough to ensure a good seal. Figure 2 shows the same rounding 29 as in Figure 1.

La figure 3 montre une construction utilisant un mouvement mécanique à remontage automatique dont la hauteur est de 5,05 mm., ce qui donne une hauteur totale de la montre de 9,95 mm. Comme en figure 2, et pour économiser de la place en hauteur hors-tout, on retrouve ici un bas de lunette 4 équipé d'une saillie 27. On remarque ici que la partie apparente de la lunette est enjolivée par deux arrondis 25 et 26 présentant des rayons différents.Figure 3 shows a construction using a mechanical movement with automatic winding whose height is 5.05 mm., Which gives a total height of the watch of 9.95 mm. As in Figure 2, and to save space in overall height, we find here a bezel bottom 4 equipped with a projection 27. We note here that the visible part of the bezel is embellished by two rounded 25 and 26 with different rays.

L'invention n'est pas limitée aux mouvements illustrés en exemple aux figures 1, 2 et 3. D'autres mouvements différents par leur hauteur et diamètre pourraient être utilisés.The invention is not limited to the movements illustrated by way of example in FIGS. 1, 2 and 3. Other movements different in their height and diameter could be used.

La figure 1a est une coupe à 3 heures de la boîte de montre représentée en figure 1 en coupe à 9 heures. La figure la montre que des passages 23 et 24 sont pratiqués respectivement dans la carrure 1 et le cadre 2. Le passage 23 pratiqué dans la carrure est agencé pour recevoir un tube 30 chassé dans ce passage. On voit que le tube 30 déborde de la carrure par son extrémité 32 dirigée vers l'intérieur de la boite. Cette extrémité 32 est engagée dans un logement 31 pratiqué dans le cadre 2. On comprendra que cette disposition permet une orientation correcte du cadre par rapport à la carrure, de telle manière que les passages 23 et 24 se trouvent alignés quand le cadre est monté dans la carrure. Le tube 30 et le passage 24 reçoivent de façon connue, une tige de commande (non représentée). On comprendra que des moyens d'orientation du mouvement par rapport au cadre seront également mis en oeuvre pour que l'entrée de la tige dans le mouvement se trouve en face du passage 24 pratiqué dans le cadre. Ces moyens pourraient consister en un ergot émergeant du mouvement, ergot qui coopère avec un logement pratiqué dans le cadre.Figure 1a is a section at 3 o'clock of the watch case shown in Figure 1 in section at 9 o'clock. Figure la shows that passages 23 and 24 are made respectively in the middle part 1 and the frame 2. The passage 23 made in the middle part is arranged to receive a tube 30 driven into this passage. We see that the tube 30 projects from the middle part by its end 32 directed towards the inside of the case. This end 32 is engaged in a housing 31 formed in the frame 2. It will be understood that this arrangement allows correct orientation of the frame with respect to the middle part, so that the passages 23 and 24 are aligned when the frame is mounted in the build. The tube 30 and the passage 24 receive, in known manner, a control rod (not shown). It will be understood that means for orienting the movement relative to the frame will also be used so that the entry of the rod into the movement is opposite the passage 24 made in the frame. These means could consist of a lug emerging from the movement, lug which cooperates with a housing made in the frame.

Le montage de la montre dont la boîte fait l'objet de la présente invention, est réalisé par la succession des étapes suivantes: on fournit une carrure 1 dans laquelle on vient emboîter un cadre d'encageage 2. On introduit un mouvement 6 dans le cadre, puis un cadran 7 sur le mouvement. On introduit à force une lunette 4, puis on pose les aiguilles 8. On colle une glace 5 à la lunette. On remarquera que toutes les opérations décrites jusqu'ici se font par le haut, ce qui simplifie considérablement l'assemblage de la montre sur machines automatiques. La dernière opération consiste à fermer la montre par un fond 3, ce qui se pratique généralement après retournement de la boîte.The assembly of the watch, the case of which is the subject of the present invention, is carried out by the succession of the following steps: a middle part 1 is provided in which a casing frame 2 is fitted. A movement 6 is introduced into the frame, then a dial 7 on the movement. A bezel 4 is forced in, then the needles 8 are placed. A window 5 is glued to the bezel. Note that all the operations described so far are done from above, which considerably simplifies the assembly of the watch on automatic machines. The last operation consists in closing the watch with a bottom 3, which is generally done after turning the case over.

Ainsi, pour les trois modes d'exécution présentés, l'emboîtage est toujours réalisé de la même façon puisque les caractéristiques de l'invention se retrouvent par une manière commune d'exécuter la carrure 1 et le cadre 2 et une manière commune de rapporter la lunette 4, le cadran 7, le mouvement 6 et le fond 3 sur le cadre. De ce fait, plusieurs lignes de produits peuvent être assemblées successivement par le même appareillage, moyennant des modifications mineures prenant peu de temps pour passer d'une ligne de produits à l'autre. On comprendra aussi que le cadran et les aiguilles n'étant plus liées au mouvement, on pourra changer rapidement de genre de cadran et d'aiguilles sans arrêter la chaîne de production. La même remarque peut être faite pour la lunette qui peut présenter diverses formes ou décorations sur sa partie visible.Thus, for the three embodiments presented, the casing is always carried out in the same way since the characteristics of the invention are found by a common way of executing the middle part 1 and the frame 2 and a common way of reporting the bezel 4, the dial 7, the movement 6 and the case back 3 on the frame. As a result, several product lines can be assembled successively by the same device, with minor modifications taking little time to move from one product line to another. We will also understand that the dial and the hands are no longer linked to the movement, so we can quickly change the type of dial and hands without stopping the production chain. The same remark can be made for the bezel which can have various shapes or decorations on its visible part.
