Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne une montre comprenant une boîte de montre renfermant un mouvement horloger et deux cadrans.The invention relates to a watch comprising a watch case containing a watch movement and two dials.

ETAT DE LA TECHNIQUESTATE OF THE ART

Dans le domaine des montres mécaniques ou électromécaniques il est connu de prévoir deux cadrans au sein de la boîte de la montre. Les deux cadrans servent par exemple à pouvoir afficher en même temps deux horaires de fuseaux horaires différents. Ou encore, un premier cadran peut servir à afficher l'heure, tandis qu'un deuxième cadran sert de décor ornemental pour la montre. Toutefois, l'opération de montage des cadrans dans la boîte de montre peut être complexe et contraignante pour un opérateur chargé d'assembler la montre. En outre, le réglage de la position d'un cadran par rapport à l'autre peut être rendu difficile du fait du faible espace disponible dans la boîte de montre.In the field of mechanical or electromechanical watches, it is known to provide two dials within the watch case. The two dials serve for example to be able to display at the same time two schedules of different time zones. Or, a first dial can be used to display the time, while a second dial serves as an ornamental background for the watch. However, the operation of mounting the dials in the watch case can be complex and constraining for an operator responsible for assembling the watch. In addition, adjusting the position of one dial relative to the other can be made difficult because of the small space available in the watch case.

Il est également connu des mouvements horlogers suspendus dans une boîte de montre.It is also known watch movements hanging in a watch case.

Une telle montre munie d'un mouvement horloger suspendu est par exemple décrite dans le document brevet JP H09127264 . La montre comprend une boîte de montre renfermant un cadre de support, un mouvement horloger, une pièce ornementale et un cadran. Le cadre de support est fixé à l'intérieur de la boîte de montre, et le mouvement horloger est monté dans une ouverture du cadre de sorte à être suspendu dans la boîte de montre. La pièce ornementale est montée également dans une autre ouverture du cadre, et le cadran est agencé sur une surface supérieure du cadre de support, recouvrant le mouvement et entourant la pièce ornementale via une ouverture correspondante pratiquée dans le cadran. Toutefois, la montre proposée ne comporte qu'un seul cadran, et ne permet donc pas de prévoir deux cadrans au sein de la boîte de montre.Such a watch provided with a suspended watch movement is for example described in the patent document JP H09127264 . The watch includes a watch case enclosing a support frame, a watch movement, an ornamental piece and a dial. The support frame is fixed inside the watch case, and the watch movement is mounted in an opening of the frame so as to be suspended in the watch case. The ornamental piece is also mounted in another opening of the frame, and the dial is arranged on a surface top of the support frame, covering the movement and surrounding the ornamental piece via a corresponding aperture in the dial. However, the proposed watch has only one dial, and therefore does not allow to provide two dials within the watch case.

RÉSUMÉ DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention a donc pour but de fournir une montre munie d'un mouvement horloger suspendu et de deux cadrans, permettant de faciliter le montage des cadrans dans la boîte de montre, et de positionner précisément les cadrans l'un par rapport à l'autre.The object of the invention is therefore to provide a watch provided with a suspended watch movement and two dials, making it possible to facilitate the mounting of the dials in the watch case, and to precisely position the dials relative to one another. other.

A cet effet, l'invention concerne une montre qui comprend les caractéristiques mentionnées dans la revendication indépendante 1.For this purpose, the invention relates to a watch which comprises the features mentioned in the independent claim 1.

Des formes particulières de la montre sont définies dans les revendications dépendantes 2 à 11.Particular shapes of the watch are defined in the dependent claims 2 to 11.

Un avantage d'une telle montre selon l'invention réside dans l'utilisation d'un cercle d'emboîtage supportant les deux cadrans, dans lequel le mouvement horloger est monté de sorte à être suspendu en porte-à-faux dans la boîte de montre. Cet unique cercle d'emboîtage permet de positionner précisément les cadrans l'un par rapport à l'autre. Le montage des cadrans dans la boîte de montre est ainsi facilité. En outre, du fait que le mouvement horloger est monté dans le cercle d'emboîtage et que le cercle présente une faible épaisseur, une grande partie de l'espace intérieur de la boîte de montre est laissé libre. Cela permet d'offrir une grande surface de décoration possible pour l'un des deux cadrans, ou encore d'ajouter des décors en trois dimensions pour la montre.An advantage of such a watch according to the invention lies in the use of a casing ring supporting the two dials, in which the watch movement is mounted so as to be suspended cantilevered in the box. shows. This unique casing circle allows precise positioning of the dials relative to each other. The mounting of the dials in the watch case is thus facilitated. In addition, because the watch movement is mounted in the casing ring and the circle has a small thickness, a large part of the interior space of the watch case is left free. This allows to offer a large decorative surface possible for one of the two dials, or to add three-dimensional decorations for the watch.

Selon un premier mode de réalisation de l'invention, les deux cadrans présentent des surfaces supérieures, le cercle d'emboîtage présentant une forme telle que les surfaces supérieures des deux cadrans sont coplanaires.According to a first embodiment of the invention, the two dials have upper surfaces, the casing ring having a shape such that the upper surfaces of the two dials are coplanar.

Selon un deuxième mode de réalisation de l'invention, les deux cadrans présentent des surfaces supérieures, le cercle d'emboîtage présentant une forme telle que les surfaces supérieures des deux cadrans sont situées à des hauteurs différentes dans la boîte de montre.According to a second embodiment of the invention, the two dials have upper surfaces, the casing ring having a shape such that the upper surfaces of the two dials are located at different heights in the watch case.

Selon un exemple de réalisation préférentiel de l'invention, l'un des deux cadrans circonscrit l'autre des cadrans dans la boîte de montre. Cela permet de conférer un aspect esthétique particulièrement intéressant à la montre.According to a preferred embodiment of the invention, one of the two dials circumscribes the other dials in the watch case. This makes it possible to confer a particularly attractive aesthetic appearance on the watch.

Selon un exemple de réalisation particulier de l'invention, la boîte de montre est munie d'une carrure et de moyens de fixation du cercle d'emboîtage sur la carrure.According to a particular embodiment of the invention, the watch case is provided with a middle and means for fixing the casing ring on the middle part.

Avantageusement, les moyens de fixation sont des vis positionnées sur le pourtour du cercle d'emboîtage, l'un des deux cadrans étant agencé sur le cercle d'emboîtage et étant muni sur son pourtour d'encoches de réception de têtes de vis, de sorte à ce que lesdites vis permettent la fixation conjointe dudit cadran sur le cercle d'emboîtage. Ceci permet de faciliter la fixation de l'ensemble des pièces au sein de la boîte de montre. En outre, un principe de fixation analogue peut être avantageusement utilisé pour permettre la fixation de décors en trois dimensions dans l'espace vide de la boîte de montre. Les décors sont alors fixés sur le cercle d'emboîtage, conjointement à la fixation du cercle lui-même sur la carrure.Advantageously, the fixing means are screws positioned on the periphery of the casing ring, one of the two dials being arranged on the casing ring and being provided on its periphery with notches for receiving screw heads, so that said screws allow the joint fixing said dial on the casing ring. This facilitates the fixing of all the parts within the watch case. In addition, a similar fastening principle can be advantageously used to allow the fixation of three-dimensional decorations in the empty space of the watch case. The decorations are then fixed on the casing ring, together with the fixing of the circle itself on the middle part.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La figure 1 représente une montre 1 munie d'une boîte de montre 2. La montre 1 comprend en outre un cercle d'emboîtage 3 agencé dans la boîte de montre 2.The figure 1 is a watch 1 provided with a watch case 2. The watch 1 further comprises a casing ring 3 arranged in the watch case 2.

La boîte de montre 2 comprend typiquement une carrure 4. La boîte de montre 2 renferme également un mouvement horloger 6 et deux cadrans 8a, 8b, agencés au sein de la carrure 4. De préférence, la boîte de montre 2 comprend en outre des moyens 10 de fixation du cercle d'emboîtage 3 sur la carrure 4.The watch case 2 typically comprises a caseband 4. The watch case 2 also contains a watch movement 6 and two dials 8a, 8b, arranged within the caseband 4. Preferably, the watch case 2 further comprises means 10 fixing the casing ring 3 on the middle part 4.

Comme illustré sur la figure 1, la carrure 4 est de forme annulaire et est posée sur un fond 12 formé dans cet exemple par une première glace (non représentée). La carrure 4 est munie en outre d'un rebord annulaire supérieur 14 sur lequel s'appuie une lunette 15. Comme illustré sur la figure 4, la lunette 15 est vissée sur la carrure 4, depuis le dessus de cette dernière. Une deuxième glace 16 est fixée dans la lunette 15, au moyen d'un joint 17 et d'un rebord supérieur 19 de la lunette 15, ces deux éléments étant visibles à la figure 4. Dans la boîte de montre 2 prise en exemple aux figures 1 à 4, la configuration de la boîte de montre est sensiblement circulaire. Toutefois, l'invention n'est nullement limitée à une telle configuration de la boîte de montre, ni aux autres dispositions décrites ci-dessus pour la carrure 4.As illustrated on the figure 1 , the caseband 4 is of annular shape and is placed on a bottom 12 formed in this example by a first mirror (not shown). The caseband 4 is further provided with an upper annular rim 14 on which a telescope 15 rests. As illustrated in FIG. figure 4 , the bezel 15 is screwed on the middle part 4, from the top of the latter. A second mirror 16 is fixed in the telescope 15, by means of a seal 17 and an upper rim 19 of the telescope 15, these two elements being visible in FIG. figure 4 . In the watch case 2 taken as an example to Figures 1 to 4 , the configuration of the watch case is substantially circular. However, the invention is not limited to such a configuration of the watch case, nor to the other arrangements described above for the caseband 4.

Comme illustré sur les figures 1, 2 et 4, le mouvement horloger 6 est monté dans le cercle d'emboîtage 3 de sorte à être suspendu en porte-à-faux dans la boîte de montre 2. Le mouvement horloger 6 est typiquement un mouvement mécanique de forme circulaire, bien que cela ne soit nullement limitatif dans le cadre de la présente invention. Le mouvement horloger 6 comporte une tige de remontoir 18 qui s'étend à l'extérieur de la boîte de montre 2, à travers un orifice 20 ménagé dans la carrure 4.As illustrated on figures 1 , 2 and 4 , the watch movement 6 is mounted in the casing ring 3 so as to be hung cantilevered in the watch case 2. The watch movement 6 is typically a circular mechanical movement, although this is not in no way limiting in the context of the present invention. The watch movement 6 comprises a winding stem 18 which extends outside the watch case 2, through an orifice 20 formed in the caseband 4.

Dans l'exemple de réalisation illustré sur les figures 1 à 4, un premier cadran 8a est un cadran horaire servant à afficher l'heure, au-dessus duquel se déplacent des moyens d'affichage formés d'aiguilles 22, couplés au mouvement horloger 6. Le premier cadran 8a est par exemple constitué de nacre, sans que cela ne soit limitatif dans le cadre de la présente invention. Un second cadran 8b est par exemple un cadran de décor, notamment une plique à jour. Dans cet exemple de réalisation particulier, le second cadran 8b circonscrit le premier cadran 8a dans la boîte de montre 2. Pour ce faire, le second cadran 8b est par exemple muni d'une ouverture 21 de forme correspondante à la forme extérieure du premier cadran 8a, typiquement une ouverture circulaire 21 sensiblement de même diamètre que le diamètre extérieur du premier cadran 8a dans l'exemple illustratif des figures 1 à 4. Dans d'autres modes de réalisation, non représentés sur les figures, le premier cadran 8a peut circonscrire le second cadran 8b dans la boîte de montre 2.In the exemplary embodiment illustrated on the Figures 1 to 4 , a first dial 8a is a time dial used to display the time, above which are moved display means formed of needles 22, coupled to the watch movement 6. The first dial 8a is for example made of mother-of-pearl, without this being limiting in the context of the present invention. A second dial 8b is for example a dial of decor, including a plique update. In this particular embodiment, the second dial 8b circumscribes the first dial 8a in the watch case 2. To do this, the second dial 8b is for example provided with an opening 21 of shape corresponding to the outer shape of the first dial. 8a, typically a circular opening 21 substantially of the same diameter as the outer diameter of the first dial 8a in the illustrative example of Figures 1 to 4 . In other embodiments, not shown in the figures, the first dial 8a may circumscribe the second dial 8b in the watch case 2.

De préférence, les moyens 10 de fixation du cercle d'emboîtage 3 sur la carrure 4 sont des vis positionnées sur le pourtour du cercle d'emboîtage 3. Le cercle d'emboîtage 3 supporte les deux cadrans 8a, 8b. Un des cadrans 8a, 8b agencés sur le cercle d'emboîtage 3, par exemple le second cadran 8b dans l'exemple illustratif de la figure 1, est muni sur son pourtour d'encoches correspondantes 23, pour la réception des têtes des vis 10. Le cercle d'emboîtage 3 est de préférence également muni sur son pourtour d'encoches 25 de réception des vis 10. Les vis 10 permettent ainsi de fixer également le cadran 8b sur le cercle d'emboîtage 3, conjointement à la fixation du cercle d'emboîtage 3 sur la carrure 4.Preferably, the means 10 for fixing the casing ring 3 to the caseband 4 are screws positioned on the periphery of the casing ring 3. The casing ring 3 supports the two dials 8a, 8b. One of the dials 8a, 8b arranged on the casing ring 3, for example the second dial 8b in the illustrative example of the figure 1 , is provided on its periphery with corresponding notches 23, for receiving the heads of the screws 10. The casing ring 3 is preferably also provided on its The screws 10 thus make it possible to fix also the dial 8b on the casing ring 3, together with the fixing of the casing ring 3 on the caseband 4.

Les deux cadrans 8a, 8b présentent des surfaces supérieures 24a, 24b. Dans un premier mode de réalisation, représenté sur les figures 1 à 6, le cercle d'emboîtage 3 présente une forme telle que les surfaces supérieures 24a, 24b des deux cadrans 8a, 8b sont coplanaires. Dans un exemple particulier de réalisation de ce premier mode, illustré sur les figures 1 à 6, le cercle d'emboîtage 3 comprend deux anneaux concentriques solidaires 26a, 26b. Comme illustré sur la figure 4, le mouvement horloger 6 est monté dans un premier anneau intérieur 26a qui supporte le premier cadran 8a. Pour ce faire, le mouvement horloger 6 comprend par exemple une collerette périphérique 6a qui vient prendre appui sur un rebord du premier anneau intérieur 26a.Both dials 8a, 8b have upper surfaces 24a, 24b. In a first embodiment, shown in the Figures 1 to 6 , the casing ring 3 has a shape such that the upper surfaces 24a, 24b of the two dials 8a, 8b are coplanar. In a particular embodiment of this first mode, illustrated on the Figures 1 to 6 , the casing ring 3 comprises two integral concentric rings 26a, 26b. As illustrated on the figure 4 , the watch movement 6 is mounted in a first inner ring 26a which supports the first dial 8a. To do this, the watch movement 6 comprises for example a peripheral flange 6a which bears on a flange of the first inner ring 26a.

Le premier cadran 8a est monté au-dessus du premier anneau intérieur 26a, sur le mouvement horloger 6 via un réhaut 27. Le premier cadran 8a est fixé sur le réhaut 27, par exemple par collage. Le réhaut 27 comporte plusieurs goupilles/pieds de cadran 29, dont une est visible à la figure 1, faisant saillie depuis une surface inférieure du réhaut. Les goupilles 29 du réhaut 27 sont insérées dans des logements correspondant 31 du mouvement horloger 6, permettant la fixation du réhaut 27 sur le mouvement 6. Le réhaut 27 est également muni d'un rebord périphérique s'étendant à travers l'ouverture 21 et portant une collerette 33. Comme illustré sur la figure 4, la collerette 33 du réhaut 27 vient prendre appui sur le second cadran 8b et recouvre une partie du second cadran 8b au niveau du bord de son ouverture 21. Ceci permet de conférer un aspect esthétique particulier à la montre 1, notamment en masquant l'interstice entre les deux cadrans 8a, 8b.The first dial 8a is mounted above the first inner ring 26a, on the watch movement 6 via a flange 27. The first dial 8a is fixed on the flange 27, for example by gluing. The flange 27 has a plurality of pins / feet 29, one of which is visible in FIG. figure 1 protruding from a lower surface of the flange. The pins 29 of the flange 27 are inserted in corresponding housings 31 of the watch movement 6, allowing the flange 27 to be fixed to the movement 6. The flange 27 is also provided with a peripheral flange extending through the opening 21 and wearing a collar 33. As illustrated on the figure 4 , the flange 33 of the flange 27 bears on the second dial 8b and covers part of the second dial 8b at the edge of its opening 21. This makes it possible to confer a particular aesthetic appearance on the watch 1, in particular by masking the interstice between the two dials 8a, 8b.

Un second anneau extérieur 26b supporte le second cadran 8b. Le cercle d'emboîtage 3 est constitué d'une seule pièce de matière usinée, par exemple, dans un matériau métallique. Le matériau métallique est typiquement de l'acier inoxydable.A second outer ring 26b supports the second dial 8b. The casing ring 3 consists of a single piece of machined material, for example, in a metallic material. The metallic material is typically stainless steel.

Comme illustré sur les figures 5 et 6, le premier anneau intérieur 26a présente une première portion 28 et une seconde portion 30. La première portion 28 comprend par exemple un rebord inférieur 32 et deux rebords supérieurs 34 de renfort. Le rebord inférieur 32 et les rebords supérieurs 34 servent ainsi de renforts pour le cercle d'emboîtage 3, conférant de la rigidité à l'ensemble. Les deux rebords supérieurs 34 sont séparés l'un de l'autre par un espacement 35, permettant le passage de la tige de remontoir 18. Un interstice correspondant 37 est prévu sur le second anneau extérieur 26b, pour le passage de la tige de remontoir 18.As illustrated on Figures 5 and 6 , the first inner ring 26a has a first portion 28 and a second portion 30. The first portion 28 comprises for example a lower flange 32 and two upper edges 34 of reinforcement. The lower flange 32 and the upper flanges 34 thus serve as reinforcements for the casing ring 3, giving rigidity to the assembly. The two upper flanges 34 are separated from each other by a spacing 35, allowing the passage of the winding stem 18. A corresponding gap 37 is provided on the second outer ring 26b, for the passage of the winding stem 18.

De préférence, au moins un des deux anneaux 26a, 26b présente une face intérieure ou extérieure satinée. Dans l'exemple illustratif des figures 5 et 6, le premier anneau intérieur 26a présente une face extérieure 36 satinée, et le second anneau extérieur 26b présente une face intérieure 38 satinée.Preferably, at least one of the two rings 26a, 26b has an inner or outer surface satin. In the illustrative example of Figures 5 and 6 , the first inner ring 26a has an outer face 36 satin, and the second outer ring 26b has an inner face 38 satin.

La configuration du cercle d'emboîtage 3 selon le premier mode de réalisation de l'invention des figures 1 à 6 et des autres éléments de la montre 1 permet ainsi de positionner précisément les cadrans 8a, 8b l'un par rapport à l'autre. En effet, en partant de cotes données pour les rebords d'appui du cercle 3 pour les cadrans 8a, 8b, il est possible de jouer sur la hauteur de la collerette 6a du mouvement 6 et sur les cotes du réhaut 27 notamment, afin d'obtenir une coplanarité pour les surfaces supérieures 24a, 24b des deux cadrans 8a, 8b.The configuration of the casing ring 3 according to the first embodiment of the invention of the Figures 1 to 6 and other elements of the watch 1 and allows to accurately position the dials 8a, 8b relative to each other. Indeed, starting from dimensions given for the bearing edges of the circle 3 for the dials 8a, 8b, it is possible to play on the height of the flange 6a of the movement 6 and on the sides of the flange 27 in particular, in order to coplanarity for the upper surfaces 24a, 24b of the two dials 8a, 8b.

Dans un deuxième mode de réalisation de l'invention, non représenté sur les figures, le cercle d'emboîtage 3 présente une forme telle que les surfaces supérieures des deux cadrans 8a, 8b sont situées à des hauteurs différentes dans la boîte de montre 2.In a second embodiment of the invention, not shown in the figures, the casing ring 3 has a shape such that the upper surfaces of the two dials 8a, 8b are located at different heights in the watch case 2.

Dans d'autres modes de réalisation, non représentés sur les figures, la montre 1 peut comprendre au moins une pièce de décor, par exemple en trois dimensions. Une telle pièce de décor est alors fixée sur le cercle d'emboîtage 3 à l'intérieur de la boîte de montre 2.In other embodiments, not shown in the figures, the watch 1 may comprise at least one piece of decoration, for example in three dimensions. Such a piece of decoration is then fixed on the casing ring 3 inside the watch case 2.

La description précédente de la montre selon l'invention a été faite en référence à un premier cadran 8a qui est un cadran horaire, et à un second cadran 8b qui est un cadran de décor. Toutefois, l'homme du métier comprendra que ces types de cadrans particuliers ne sont nullement limitatifs dans le cadre de la présente invention, et qu'en pratique tout type de cadran peut être utilisé pour chacun des deux cadrans 8a, 8b.The foregoing description of the watch according to the invention has been made with reference to a first dial 8a which is a time dial, and to a second dial 8b which is a dial of decoration. However, those skilled in the art will understand that these types of particular dials are in no way limiting in the context of the present invention, and that in practice any type of dial can be used for each of the two dials 8a, 8b.
