Description

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

Il est bien connu de proposer une boîte 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 accroît de cette façon les variantes qu'on peut proposer à l'acheteur.It is well known to provide a watch case with different dials as to their appearance. These dials can have different materials or different graphics that meet the taste of the moment. Thus during assembly, the SWATCH watch (registered trademark) can be equipped with one of the multiple dials designed by the imagination of stylists. These dials, however, have only one and only one dimension, circular in the majority of cases. However, it has proven useful to be able to offer not only dials with various graphics, but also, for the same build, dials whose dimensions differ. This increases the variants that can be offered to the 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 steps to receive a choice and respectively a first dial having a first dimension or a second dial having a second larger 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 boîte 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 boîte 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 boîte 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 boîte 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 showing a third embodiment of said invention.

La boîte 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 boîte 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 presented in FIGS. 1 and 2 comprises a middle part 1 and a base 2. FIG. 1 is a section made at 6 o'clock or at 12 o'clock, since there is shown there a housing 26 which serves to retain a bracelet. Figure 2 is a section at 3 o'clock showing the bore 25 intended to be crossed by a time-setting rod. The box is capable of receiving a movement, not shown, which takes place in the space referenced 27. The movement is surmounted by a dial 9 or 10 and a set of hands 6 or 5 respectively. The figures show a bottom 2 made of a part with the middle part 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 chaîne 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 in that the middle part 1 has at least a first shoulder 7 and a second shoulder 8 arranged in steps. In the case of Figure 1, the first shoulder 7 receives a first dial 9 having a first dimension. In the case of FIG. 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 step. Thus during assembly, carried out for example on an automatic chain, one can choose to equip the watch either with a dial 9 of small dimension, or with 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 the small size dial 9 is adapted to a first type of ice 11 also small. To fill the void created between the glass 11 and the edge of the middle part 1 has been arranged a bezel 13. This bezel, in addition to hiding the free space of the second shoulder 8 which is not used, makes it possible to bring the watch an attractive aesthetic appearance. It is mounted notch on the ice and can be fixed or rotating. The dial 9 is surmounted by a set of short needles 6 adapted to the dimensions of the dial 9 and 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.FIG. 2 shows that a second type of glass 12 also having a large dimension is fitted to the large dial 10. The glass 12 joins the edge of the middle part 1 without it being necessary to provide a telescope. The dial 10 is surmounted by a set of needles 5 of larger dimension, adapted to the 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 boîte 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 sets of needles 6 and 5 are located at an equal distance from the windows 11 and 12, which makes it possible to use the same type of movement with a similar needle axis. With regard to the movement, it should be noted that it may be an independent movement mounted by the top of the case or a movement mounted on the bottom 2 as is well known from the SWATCH watch cited above. . To return to the sets of hands, it will be noted that, in the case of FIG. 2, the set 5 is closer to the dial 10 and that, in the case of FIG. 1, the set 6 is located further 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.The middle part 1 and the two types of glass 11 and 12 shown in FIG. 1 and 2 are made of heat-sealable thermoplastic materials. For example, the middle part 1 is made of a material chosen from the group comprising acrylic butadiene styrene (ABS) and the glasses 11 and 12 are made of a transparent acrylic resin (PMMA). Means are provided for assembling one or the other lens and the middle part, 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, to maintain the chosen dial 9 or 10 on its corresponding shoulder 7 or 8 when the crystal is assembled to the middle part. The interested reader will profitably read a description of this technique in document EP-B-0 101 663 (US-A-4 558 957). It is therefore not necessary 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.Thus, in summary of what has been explained above, it is easily possible, during assembly of the watch, to choose a dial 9 of small dimension 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. Each of these dials has a corresponding crystal, one with a bezel and the other without a bezel. 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 both cases, in fact, the middle part 1 is shaped to receive a single type of glass, either the glass 18 of FIG. 3 or the glass 19 of FIG. 4. These glass 18 or 19 are adapted either to the second dial 10 of large dimension when the latter is housed on the second shoulder 8, that is to say a ring 20 housed in said second shoulder 8, this ring now in place the first dial 9 when the latter 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 tightening surface 17 which holds in place a ring 20 housed on the second shoulder 8, this ring in turn holding in place a dial 9 of small dimension housed on the first shoulder 7. In this case, and without it being necessary to represent it, if a large dial 10 was chosen, it would be housed on the shoulder 8 and retained by the clamping surface 17, the ring 20 then failing. The dial 9 corresponds to the set of short needles 6 and to the dial 10 the set of long needles 5. In this second embodiment, the middle part 1 and the crystal 18 are made, as in the first mode, of plastic materials heat sealable, means being provided for assembling the crystal and the middle part, these means consisting of a localized zone 21 constituted by a mixture of the 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 lining 22 interposed between these elements. In this case, the middle part 1 is preferably metallic and the lens 19 is made of glass. A flange 23 is located under the glass 19 and this flange has an annular tightening surface 24 which holds in place a large dial 10 housed on its shoulder 8. Here also and without it being necessary to represent it, if a dial 9 of small dimension was chosen, it would be housed on the shoulder 7 and retained in place by a ring 20 (see FIG. 3) itself held in place by the clamping surface 24 of the flange 23. The dial 10 corresponds preferably a set of long hands 5 and on the dial 9, a set of short hands 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.The ring 20 provided for the second and third embodiments, superimposed in step on the dial 9 of small dimension, gives a particular appearance to the watch and can be coated with an original or personalized graphics.

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, it will be noted that, for one or other of the modes chosen, the peripheral shape of the dials and the glass has not been mentioned above. These can be circular or any other shape.
