Description

La présente invention concerne une boíte de montre comportant une carrure et un fond, ladite boíte étant destinée à recevoir un mouvement surmonté d'un cadran et d'un jeu d'aiguilles.The present invention relates to a watch case having a middle and a bottom, said box being intended to receive a movement surmounted by a dial and a set of needles.

Il est bien connu (EP-A-0 199 298) de proposer une boíte de montre avec des cadrans différents quant à leur aspect. Ces cadrans peuvent présenter des matériaux différents ou encore des graphismes divers répondant au goût du moment. C'est ainsi qu'en cours de montage, la montre SWATCH (marque déposée) peut être équipée d'un des multiples cadrans conçus par l'imagination des stylistes. Ces cadrans cependant ne présentent qu'une seule est unique dimension, circulaire dans la majorité des cas. Or il s'est avéré utile de pouvoir proposer non seulement des cadrans présentant des graphismes variés, mais encore, pour une même carrure, des cadrans dont les dimensions diffèrent. On accroít de cette façon les variantes qu'on peut proposer à l'acheteur.It is well known (EP-A-0 199 298) to propose a watch case with different dials as to their appearance. These dials may have different materials or still various graphics responding to the taste of the moment. This is how, during assembly, the SWATCH watch (registered trademark) can be equipped with one of the multiples dials designed by the imagination of stylists. These dials however only have one is unique dimension, circular in most cases. But he has proven useful to be able to offer not only dials with various graphics, but still, for the same middle, dials whose dimensions different. In this way we increase the variants we can offer to buyer.

Pour obtenir ce résultat, la présente invention est caractérisée en ce que la carrure présente au moins des premier et second épaulements annulaires disposés en gradins pour recevoir au choix et respectivement un premier cadran présentant une première dimension ou un second cadran présentant une seconde dimension plus grande que la première.To obtain this result, the present invention is characterized in that the middle part has at least first and second annular shoulders arranged in bleachers to receive a choice and respectively a first dial with a first dimension or a second dial with a larger second dimension than the first.

L'invention sera comprise maintenant à la lecture de la description qui suit et illustrée par le dessin donnant plusieurs exemples de mode de réalisation, dessin dans lequel :

  • la figure 1 est une coupe dans la boíte de montre de l'invention où le cadran qui y est montré présente une première dimension réduite,
  • la figure 2 est une coupe dans la même boíte de montre où le cadran qui y est montré présente une seconde dimension plus grande que celle de la figure 1,
  • la figure 3 est une coupe dans la boíte de montre de l'invention, cette coupe présentant un deuxième mode d'exécution de ladite invention, et
  • la figure 4 est une coupe dans la boíte de montre de l'invention, cette coupe présentant un troisième mode d'exécution de ladite invention.
The invention will now be understood on reading the description which follows and illustrated by the drawing giving several examples of embodiment, drawing in which:
  • FIG. 1 is a section through the watch case of the invention where the dial which is shown there has a reduced first dimension,
  • FIG. 2 is a section in the same watch case where the dial which is shown there has a second dimension larger than that of FIG. 1,
  • FIG. 3 is a section through the watch case of the invention, this section showing a second embodiment of said invention, and
  • Figure 4 is a section in the watch case of the invention, this section having a third embodiment of said invention.

La boíte de montre présentée aux figures 1 et 2 comporte une carrure 1 et un fond 2. La figure 1 est une coupe faite à 6 heures ou à 12 heures, car on y voit représenté un logement 26 qui sert à retenir un bracelet. La figure 2 est une coupe à 3 heures faisant voir le perçage 25 destiné à être traversé par une tige de mise à l'heure. La boíte est susceptible de recevoir un mouvement non représenté qui prend place dans l'espace référencé 27. Le mouvement est surmonté d'un cadran 9 ou 10 et d'un jeu d'aiguilles 6 ou 5 respectivement. Les figures font état d'un fond 2 fait d'une pièce avec la carrure 1, mais il est clair que le fond 2 pourrait être indépendant.The watch case shown in Figures 1 and 2 has a middle part 1 and a bottom 2. Figure 1 is a cut made at 6 o'clock or at 12 o'clock, because we can see there shown a housing 26 which serves to retain a bracelet. Figure 2 is a section at 3 o'clock showing the hole 25 intended to be crossed by a setting rod time. The box is likely to receive a movement not shown which takes place in the space referenced 27. The movement is surmounted by a dial 9 or 10 and a game needles 6 or 5 respectively. The figures show of a back 2 made of a piece with the middle 1, but it is clear that the bottom 2 could be independent.

Comme on le voit sur les figures 1 et 2, l'invention est principalement caractérisée par le fait que la carrure 1 présente au moins un premier épaulement 7 et un second épaulement 8 disposés en gradins. Dans le cas de la figure 1, le premier épaulement 7 reçoit un premier cadran 9 présentant une première dimension. Dans le cas de la figure 2, le second épaulement 8 reçoit un second cadran 10 présentant une seconde dimension plus grande que la première, la cadran 10 étant logé sur le gradin supérieur. Ainsi en cours de montage, réalisé par exemple sur chaíne automatique, on peut choisir de doter la montre soit d'un cadran 9 de petite dimension, soit d'un cadran 10 de grande dimension.As seen in Figures 1 and 2, the invention is mainly characterized by the fact that the middle 1 has at least a first shoulder 7 and a second shoulder 8 arranged in tiers. In the case of the figure 1, the first shoulder 7 receives a first dial 9 presenting a first dimension. In the case of Figure 2, the second shoulder 8 receives a second dial 10 having a second dimension larger than the first, the dial 10 being housed on the upper tier. Thus during assembly, carried out for example on chain automatic, you can choose to equip the watch with either dial 9 of small dimension, that is to say of a dial 10 of large dimension.

La figure 1 montre qu'au cadran 9 de petite dimension est adapté un premier type de glace 11 de petite dimension également. Pour combler le vide crée entre la glace 11 et le bord de la carrure 1 a été disposée une lunette 13. Cette lunette, en plus qu'elle cache l'espace libre du second épaulement 8 non utilisé, permet d'apporter à la montre un aspect esthétique intéressant. Elle est montée à cran sur la glace et peut être fixe ou tournante. Le cadran 9 est surmonté d'un jeu d'aiguilles 6 courtes adapté aux dimensions du cadran 9 et de la glace 11.Figure 1 shows that on small dial 9 is adapted a first type of ice 11 of small dimension also. To fill the void created between the glass 11 and the edge of the middle part 1 has been arranged a bezel 13. This glasses, in addition to hiding the free space of the second shoulder 8 not used, allows bringing to the shows an interesting aesthetic aspect. She went up to notch on the ice and can be fixed or rotating. The dial 9 is surmounted by a set of 6 short hands adapted to the dimensions of the dial 9 and of the crystal 11.

La figure 2 montre qu'au cadran 10 de grande dimension est adapté un second type de glace 12 présentant également une grande dimension. La glace 12 rejoint le bord de la carrure 1 sans qu'il soit nécessaire de prévoir une lunette. Le cadran 10 est surmonté d'un jeu d'aiguilles 5 de plus grande dimension, adapté aux dimensions du cadran 10 et de la glace 12.Figure 2 shows that on dial 10 of large dimension is suitable a second type of ice 12 having also a great dimension. Ice 12 joins the edge of middle part 1 without having to provide a telescope. The dial 10 is surmounted by a game of larger needles 5, suitable for dimensions of the dial 10 and of the crystal 12.

On observera que, dans les deux cas, les jeux d'aiguilles 6 et 5 se trouvent situés à égale distance des glaces 11 et 12 ce qui permet d'utiliser un même type de mouvement avec un axe d'aiguilles semblable. En ce qui concerne le mouvement on notera qu'il peut s'agir d'un mouvement indépendant monté par le haut de la boíte ou d'un mouvement monté à même le fond 2 comme cela est bien connu de la montre SWATCH cité plus haut. Pour revenir aux jeux d'aiguilles, on remarquera que, dans le cas de la figure 2, le jeu 5 se trouve plus près du cadran 10 et que, dans le cas de la figure 1, le jeu 6 se trouve plus éloigné du cadran 9.It will be observed that, in both cases, the games needles 6 and 5 are located equidistant from windows 11 and 12 which allows the same type of movement with a similar needle axis. In what concerns the movement note that it can be a independent movement mounted by the top of the box or of a movement mounted on the bottom 2 as well known from the SWATCH watch cited above. To return to sets of needles, it will be noted that, in the case of the Figure 2, the game 5 is closer to the dial 10 and that, in the case of FIG. 1, the set 6 is more away from the dial 9.

La carrure 1 et les deux types de glace 11 et 12 montrés en figure 1 et 2 sont réalisés en matériaux thermoplastique thermosoudables. Par exemple la carrure 1 est réalisée dans un matériau choisi dans le groupe comprenant l'acryl butadiène styrène (ABS) et les glaces 11 et 12 sont réalisées en une résine transparente acrylique (PMMA). Des moyens sont prévus pour assembler l'une ou l'autre glace et la carrure, ces moyens comprenant une zone localisée 14 ou 15 constituée par un mélange desdits matériaux thermosoudables entre eux. Les deux types de glace 11 et 12 présentent en outre une surface annulaire de serrage 16, respectivement 17, pour maintenir le cadran choisi 9 ou 10 sur son épaulement correspondant 7 ou 8 quand la glace est assemblée à la carrure. Le lecteur intéressé lira avec profit une description de cette technique dans le document EP-B-0 101 663 (US-A-4 558 957). Il n'est donc pas nécessaire de s'étendre ici plus avant sur ce procédé.Frame 1 and the two types of glass 11 and 12 shown in figure 1 and 2 are made of materials thermosealable thermoplastic. For example, middle 1 is made of a material chosen from the group including acryl butadiene styrene (ABS) and ice 11 and 12 are made of a transparent resin acrylic (PMMA). Means are provided for assembling one or the other glass and the middle, these means comprising a localized zone 14 or 15 constituted by a mixture of said heat-sealable materials together. The two types of ice 11 and 12 also have a annular clamping surface 16, respectively 17, for keep the chosen dial 9 or 10 on its shoulder corresponding 7 or 8 when the glass is assembled to the middle. The interested reader will profitably read a description of this technique in document EP-B-0 101 663 (US-A-4,558,957). There is therefore no need to expand here further on this process.

Ainsi, en résumé de ce qui a été expliqué ci-dessus, il est facilement possible, en cours de montage de la montre, de choisir un cadran 9 de petite dimension ou un cadran 10 de plus grande dimension, ces cadrans s'adaptant à la même carrure 1 grâce au fait que ladite carrure possède deux épaulements différents disposés en gradins. A chacun de ces cadrans correspond une glace idoine, l'une avec lunette et l'autre dépourvue de lunette. Ceci correspond à un premier mode d'exécution de l'invention. On peut imaginer d'autres modes d'exécution de l'invention dont deux vont être passés en revue ci-après.So, in summary of what has been explained above, it is easily possible, during assembly of the watch, choose a small dial 9 or a dial 10 of larger dimension, these dials adapting to the same middle 1 thanks to the fact that said middle has two different shoulders arranged in steps. AT each of these dials corresponds to a suitable crystal, one with glasses and the other without glasses. This corresponds to a first embodiment of the invention. One can imagine other embodiments of the invention two of which will be reviewed below.

Les figures 3 et 4 illustrent respectivement des second et troisième modes d'exécution de l'invention. Ces modes d'exécution présentent des points communs. Dans les deux cas en effet, la carrure 1 est conformée pour recevoir un seul type de glace, soit la glace 18 de la figure 3 ou la glace 19 de la figure 4. Ces glaces 18 ou 19 sont adaptées soit au second cadran 10 de grande dimension quand ce dernier est logé sur le second épaulement 8, soit à un anneau 20 logé dans ledit second épaulement 8, cet anneau maintenant en place le premier cadran 9 quand celui-ci est logé sur le premier épaulement 7.Figures 3 and 4 respectively illustrate second and third embodiments of the invention. These modes of execution have common points. In the two cases indeed, the middle part 1 is shaped to receive only one type of ice, namely ice 18 of the Figure 3 or the window 19 of Figure 4. These windows 18 or 19 are adapted either to the second dial 10 of large dimension when the latter is housed on the second shoulder 8, or to a ring 20 housed in said second shoulder 8, this ring now in place the first dial 9 when it is housed on the first shoulder 7.

En figure 3, la glace 18 de grande dimension présente une surface annulaire de serrage 17 qui maintien en place un anneau 20 logé sur le second épaulement 8, cet anneau maintenant à son tour en place un cadran 9 de petite dimension logé sur le premier épaulement 7. Dans ce cas, et sans qu'il soit nécessaire de la représenter, si un cadran 10 de grande dimension était choisi, il serait logé sur l'épaulement 8 et retenu par la surface de serrage 17, l'anneau 20 faisant alors défaut. Au cadran 9 correspond le jeu d'aiguilles courtes 6 et au cadran 10 le jeu d'aiguilles longues 5. Dans ce second mode d'exécution, la carrure 1 et la glace 18 sont réalisées, comme dans le premier mode, en matériaux plastiques thermosoudables, des moyens étant prévus pour assembler la glace et la carrure, ces moyens consistant en une zone localisée 21 constituée par un mélange des matériaux thermosoudables entre eux.In FIG. 3, the large-sized glass 18 has an annular clamping surface 17 which holds in place a ring 20 housed on the second shoulder 8, this ring now in turn place a small 9 dial dimension housed on the first shoulder 7. In this case, and without it being necessary to represent it, if a dial 10 large was chosen, it would be housed on the shoulder 8 and retained by the clamping surface 17, the ring 20 then failing. Dial 9 corresponds the set of short hands 6 and the dial 10 the set long needles 5. In this second embodiment, the middle 1 and glass 18 are made, as in the first mode, in heat-sealable plastic materials, means being provided for assembling the crystal and the middle part, these means consisting of a localized zone 21 constituted by a mixture of heat-sealable materials together.

En figure 4, la glace 19 et la carrure 1 sont assemblées au moyen d'une garniture compressible 22 interposée entre ces éléments. Dans ce cas, la carrure 1 est métallique de préférence et la glace 19 est en verre. Un réhaut 23 se trouve situé sous la glace 19 et ce réhaut présente une surface annulaire de serrage 24 qui maintient en place un cadran 10 de grande dimension logé sur son épaulement 8. Ici également et sans qu'il soit nécessaire de le représenter, si un cadran 9 de petite dimension était choisi, il serait logé sur l'épaulement 7 et retenu en place par un anneau 20 (voir figure 3) lui-même maintenu en place par la surface de serrage 24 du réhaut 23. Au cadran 10 correspond préférablement un jeu d'aiguilles longues 5 et au cadran 9, un jeu d'aiguilles courtes 6.In FIG. 4, the glass 19 and the middle part 1 are assembled by means of a compressible packing 22 interposed between these elements. In this case, the middle 1 is preferably metallic and the glass 19 is made of glass. A flange 23 is located under the glass 19 and this flange has an annular clamping surface 24 which maintains in place a large dial 10 housed on its shoulder 8. Here also and without the need to represent it, if a small dial 9 was chosen, it would be housed on shoulder 7 and retained in place by a ring 20 (see Figure 3) itself held in place by the clamping surface 24 of the flange 23. Dial 10 preferably has a clearance long needles 5 and dial 9, a set of needles short 6.

L'anneau 20 prévu pour les deuxième et troisième modes d'exécution, superposé en gradin au cadran 9 de petite dimension, confère un aspect particulier à la montre et peut être revêtu d'un graphisme original ou personnalisé.Ring 20 planned for the second and third embodiments, superimposed in tier on dial 9 of small dimension, gives a particular aspect to the shows and can be coated with an original graphic or personalized.

On remarquera enfin qu'il n'a pas été fait mention ci-dessus, pour l'un ou l'autre des modes choisis, de la forme périphérique des cadrans et des glaces. Ceux-ci peuvent être circulaires ou de toute autre forme.Finally, we note that it was not mentioned above, for one or other of the modes chosen, the peripheral shape of the dials and glass. These can be circular or any other shape.
