Description

Dispositif indicateur de fuseaux horaires  Time zone indicating device
Domaine de l'invention Field of the invention
L'invention se rapporte à une pièce d'horlogerie équipée d'un dispositif indicateur de fuseaux horaires pour les pièces d'horlogerie. Arrière-plan de l'invention The invention relates to a timepiece equipped with a time zone indicator device for timepieces. Background of the invention
Les montres permettant d'indiquer l'heure dans un ou plusieurs fuseaux horaires différents existent depuis longtemps et comprennent généralement des mécanismes compliqués. De manière classique, ces montres comprennent une aiguille supplémentaire pour indiquer l'heure dans un autre fuseau horaire choisi par le porteur, ce qui n'est pas pratique à régler et/ou à corriger ou bien mettre à l'heure en cas d'arrêt de la montre. Watches for indicating the time in one or more different time zones have existed for a long time and generally include complicated mechanisms. Typically, these watches include an additional hand to indicate the time in another time zone chosen by the wearer, which is not practical to adjust and / or correct or set the time in case of stop the watch.
Le document CH 685 584 tente de remédier à ce problème en proposant une montre comportant un indicateur des heures prévu pour effectuer un tour en douze heures et indiquer l'heure sous l'un des fuseaux horaires, et un indicateur des minutes prévu pour effectuer un tour en une heure, et comprenant un mouvement entraînant directement l'indicateur des minutes, et un organe tournant indicateur d'au moins deux fuseaux horaires et entraînable manuellement en rotation. Le mouvement est monté rotatif dans une boîte comprenant, en prise entre le mouvement et l'organe indicateur de fuseaux horaires, un premier train d'engrenage et un deuxième train d'engrenage permettant de déplacer l'aiguille des heures et des minutes lorsque le mouvement est mis en rotation. The document CH 685 584 attempts to remedy this problem by proposing a watch having an indicator of the hours provided for performing a tour in twelve hours and indicating the time under one of the time zones, and a minute indicator provided for performing a revolution in one hour, and comprising a movement directly causing the minute indicator, and a rotating member indicating at least two time zones and manually rotatable. The movement is rotatably mounted in a box comprising, engaged between the movement and the time zone indicator member, a first gear train and a second gear train for moving the hour and minute hand when the movement is rotated.
Un inconvénient d'un tel type de montre est que le mécanisme est relativement compliqué, notamment pour une montre mécanique. De plus, un tel agencement augmente sensiblement l'épaisseur de la montre, ce qui nuit à l'esthétique de cette dernière. Enfin, un tel mécanisme semble fragile et le moindre choc pourrait le dérégler voir l'abimer. Résumé de l'invention A disadvantage of such a type of watch is that the mechanism is relatively complicated, especially for a mechanical watch. In addition, such an arrangement substantially increases the thickness of the watch, which affects the aesthetics of the latter. Finally, such a mechanism seems fragile and the slightest shock could disrupt it or damage it. Summary of the invention
L'invention a notamment pour objectif de pallier les différents inconvénients de ces techniques connues. The invention particularly aims to overcome the various disadvantages of these known techniques.
Plus précisément, un objectif de l'invention est de fournir une montre avec un dispositif d'affichage de fuseaux horaires permettant un changement intuitif et simplifié entre les différents fuseaux horaires. More specifically, an object of the invention is to provide a watch with a time zone display device allowing an intuitive and simplified change between the different time zones.
Un autre objectif de l'invention est de fournir une montre avec un dispositif d'affichage de fuseaux horaires qui soit simple et peu coûteux à mettre en œuvre. Ces objectifs, ainsi que d'autres qui apparaîtront plus clairement par la suite, sont atteints selon l'invention à l'aide d'une pièce d'horlogerie comprenant au moins un indicateur des heures, un indicateur des minutes, un mouvement agencé pour entraîner l'indicateur des heures et l'indicateur des minutes, un cadran, un rehaut, une couronne et un indicateur d'au moins un fuseau horaire, logés dans un premier boîtier. Another object of the invention is to provide a watch with a time zone display device that is simple and inexpensive to implement. These objectives, as well as others which will appear more clearly later, are achieved according to the invention with the aid of a timepiece comprising at least one hour indicator, a minute indicator, a movement arranged to driving the hour indicator and the minute indicator, a dial, a flange, a crown and an indicator of at least one time zone, housed in a first housing.
Selon l'invention, le premier boîtier est mobile en rotation dans un deuxième boîtier autour d'un axe de rotation confondu avec l'axe de rotation des indicateurs des heures et des minutes, de manière qu'une rotation du premier boîtier dans le sens horaire ou antihoraire par rapport au deuxième boîtier permet de choisir un fuseau horaire et d'indiquer l'heure du fuseau horaire choisi. According to the invention, the first housing is rotatable in a second housing around an axis of rotation coinciding with the axis of rotation of the hours and minutes indicators, so that a rotation of the first housing in the direction time or counterclockwise relative to the second housing allows you to choose a time zone and indicate the time of the chosen time zone.
Ainsi, l'objet de la présente invention, par ses différents aspects fonctionnels et structurels décrits ci-dessus, permet d'obtenir une montre avec un mécanisme indicateur de fuseaux horaires relativement simple tout en prodiguant un réglage aisé et intuitif. Thus, the object of the present invention, by its various functional and structural aspects described above, makes it possible to obtain a watch with a relatively simple time zone indicating mechanism while providing an easy and intuitive adjustment.

Detailed Description of the Preferred Embodiments
Une pièce d'horlogerie avec un dispositif d'affichage de fuseaux horaires conforme à l'invention va maintenant être décrite dans ce qui suit faisant référence conjointement aux figures 1 à 6. A timepiece with a time zone display device according to the invention will now be described in the following with reference to Figures 1 to 6.
Comme on peut l'observer à la figure 1 , la montre comprend un mouvement usuel, emboîté dans un premier boîtier 1 , le boîtier comprenant un cadran 3 entouré et surmonté par un rehaut 2, une glace surmontant le rehaut 2, et une collerette 4 entourant la glace pour former un épaulement 40 sur le pourtour supérieur du premier boîtier 1 . Le mouvement emboîté peut aussi bien être un mouvement mécanique qu'un mouvement à quartz ou encore un mouvement électromécanique, le mouvement étant agencé pour entraîner un indicateur des heures 6 et un indicateur des minutes 7. Dans le cas d'un affichage douze heures l'indicateur des heures 6 effectue un tour de cadran en douze heures, et dans le cas d'un affichage vingt-quatre heures l'indicateur des heures 6 effectue un tour de cadran en vingt-quatre heures. As can be seen in FIG. 1, the watch comprises a usual movement, fitted into a first casing 1, the casing comprising a dial 3 surrounded and surmounted by a flange 2, an ice-cream surmounting the flange 2, and a flange 4 surrounding the ice to form a shoulder 40 on the upper periphery of the first housing 1. The nested movement can it may be a mechanical movement or a quartz movement or an electromechanical movement, the movement being arranged to cause an hour indicator 6 and a minute indicator 7. In the case of a twelve hour display the hour indicator 6 performs a turn of the dial in twelve hours, and in the case of a twenty-four hour display the hour indicator 6 performs a dial revolution in twenty-four hours.
Selon l'invention, la montre comprend également un deuxième boîtier 10 présentant une partie inférieure 12 vissée sur une partie supérieure 1 1 , 1a partie supérieure comprenant des cornes 1 10 pour pouvoir attacher un bracelet. Selon un aspect particulièrement avantageux de l'invention, le premier boîtier 1 est monté rotatif dans le deuxième boîtier 10. De manière évidente, les cornes peuvent aussi être supportées par la partie inférieure 12 du deuxième boîtier 10. According to the invention, the watch also comprises a second housing 10 having a lower portion 12 screwed to an upper part 1 1, the upper part comprising horns 1 10 to be able to attach a bracelet. According to a particularly advantageous aspect of the invention, the first housing 1 is rotatably mounted in the second housing 10. Obviously, the horns can also be supported by the lower portion 12 of the second housing 10.
Comme on peut le voir sur la figure 2, le premier boîtier 1 comprend respectivement sur sa partie supérieure et sur sa partie inférieure, une collerette 4, 4' et un épaulement 40,40', chaque ensemble formant un rebord annulaire périphérique agencé pour coopérer avec une ouverture circulaire formée dans chacune des parties supérieure 1 1 et inférieure 12 du deuxième boîtier 10. Le premier boîtier 1 est donc maintenu dans le deuxième boîtier 10 de manière à permettre uniquement une rotation du premier boîtier 1 autour d'un axe A confondu avec l'axe de rotation des indicateurs des heures 6 et des minutes 7. As can be seen in FIG. 2, the first housing 1 comprises respectively on its upper part and on its lower part, a flange 4, 4 'and a shoulder 40, 40', each assembly forming a peripheral annular flange arranged to cooperate with a circular opening formed in each of the upper parts 1 1 and lower 12 of the second housing 10. The first housing 1 is thus maintained in the second housing 10 so as to allow only a rotation of the first housing 1 about a coinciding axis A with the axis of rotation of the indicators of hours 6 and minutes 7.
Selon le mode de réalisation illustré à la figure 3a, le premier boîtier 1 comprend des tronçons 8 sur sa tranche, chaque tronçon 8 recevant un fuseau horaire. Selon un autre mode de réalisation illustré à la figure 3b, c'est le rehaut 2 qui reçoit les différents fuseaux horaires, qui peuvent être au nombre de douze ou vingt-quatre par exemple. Encore selon un autre mode de réalisation visible aux figure 4a et 5a, les fuseaux sont affichés sur le fond du premier boîtier 1 , le fond étant visible au travers de la partie inférieure du deuxième boîtier 10. De manière à améliorer l'utilisation de la montre, chaque fuseau comprend un signe + ou - pour que le porteur puisse déterminer s'il fait jour ou nuit dans le fuseau choisi. According to the embodiment illustrated in Figure 3a, the first housing 1 comprises sections 8 on its edge, each section 8 receiving a time zone. According to another embodiment illustrated in FIG. 3b, it is the flange 2 which receives the different time zones, which may be twelve or twenty-four, for example. Still according to another embodiment visible in FIGS. 4a and 5a, the spindles are displayed on the bottom of the first housing 1, the bottom being visible through the lower part of the second housing 10. In order to improve the use of the watch, each spindle includes a + or - sign so that the wearer can determine whether it is day or night in the selected spindle.
Selon l'invention, l'indicateur indiquant le fuseau horaire doit être solidaire et tourner avec le premier boîtier 1 , l'heure affichée étant celle du fuseau se trouvant à midi sur le premier boîtier 1 . L'homme du métier pourrait ajouter un marqueur sur la partie fixe, à savoir le deuxième boîtier 10, pour améliorer la lecture. Un tel marqueur pourrait par exemple être un triangle inversé, une flèche ou encore un index classique. According to the invention, the indicator indicating the time zone must be integral and rotate with the first housing 1, the time displayed being that of the spindle at noon on the first housing 1. One skilled in the art could add a marker on the fixed part, namely the second housing 10, to improve the reading. Such a marker could for example be an inverted triangle, an arrow or a conventional index.
Afin de contrôler la rotation du premier boîtier 1 par rapport au deuxième boîtier 10, des moyens de verrouillage sont prévus entre le premier boîtier 1 et le deuxième boîtier 10. Plus précisément, les moyens de verrouillage comprennent au moins un cliquet à bille 41 , disposé au niveau de l'épaulement 40, 40' du premier boîtier 1 , ce cliquet à bille 41 étant agencé pour coopérer avec des trous 121 hémisphériques formés le long de la périphérie des parties inférieure et supérieure du deuxième boîtier 10. Selon le mode de réalisation représenté, il y a douze trous 121 répartis régulièrement et espacés de 30° de manière qu'une rotation d'un cran correspond à un décalage de +/- 1 heure. Dans le cas où la montre comporte un affichage de vingt-quatre heures, il y a bien évidemment vingt-quatre trous 121 . In order to control the rotation of the first housing 1 relative to the second housing 10, locking means are provided between the first housing 1 and the second housing 10. More specifically, the locking means comprise at least one ball pawl 41 disposed at the shoulder 40, 40 'of the first housing 1, this ball pawl 41 being arranged to cooperate with hemispherical holes 121 formed along the periphery of the lower and upper portions of the second housing 10. According to the embodiment shown, there are twelve holes 121 regularly distributed and spaced 30 ° so that a rotation of a notch corresponds to an offset of +/- 1 hour. In the case where the watch has a display of twenty-four hours, there are obviously twenty-four holes 121.
Il est également possible de mettre en place au moins un cliquet à bille 41 sur un seul épaulement du premier boîtier 1 , le cliquet à billet coopérant avec des trous 121 formés sur la partie supérieure 1 1 ou inférieure 12 du deuxième boîtier 10, la partie ne recevant pas de cliquet à bille pouvant alors recevoir un roulement à billes ou à rouleaux. It is also possible to put in place at least one ball pawl 41 on a single shoulder of the first housing 1, the pawl cooperating with holes 121 formed on the upper part 1 1 or lower 12 of the second housing 10, the part not receiving a ball catch that can then receive a ball or roller bearing.
L'homme du métier pourra bien évidemment trouver d'autres alternatives au cliquet à bille, tel qu'un dispositif à lame ressort illustré à la figure 6 par exemple. Un tel dispositif à lame ressort comprend une lame ressort 42 disposée dans des rainures formées au niveau des épaulements 40 et 40' du premier boîtier 1 , chaque rainure présentant une butée 44 pour maintenir la lame ressort 42 en place. Avantageusement, la lame ressort 42 comprend au moins une dent 43 agencée pour coopérer avec des rainures 122 formées dans les parties supérieure et inférieure du deuxième boîtier 10. Those skilled in the art will obviously find other alternatives to the ball catch, such as a spring blade device illustrated in Figure 6 for example. Such a spring blade device comprises a leaf spring 42 disposed in grooves formed at the shoulders 40 and 40 'of the first housing 1, each groove having a stop 44 for keep the leaf spring 42 in place. Advantageously, the spring blade 42 comprises at least one tooth 43 arranged to cooperate with grooves 122 formed in the upper and lower parts of the second housing 10.
Selon un aspect particulièrement avantageux de l'invention, l'indicateur des heures 6 est formé par un disque transparent supportant un triangle 60 indiquant l'heure courante sur le cadran qui ne porte aucun chiffre pour les heures. Un autre disque formant l'indicateur des minutes 7 est monté sur le disque des heures 6, le disque des minutes présentant une ouverture 70 laissant apparaître les minutes courantes sur le cadran, les minutes étant cette fois ci affichées sur le cadran 3 de manière numérique. Ainsi, le cadran 3 comprend deux portions, l'une sans indication numérique pour les heures, et l'autre avec des indications numériques pour les minutes. Un tel mode d'affichage permet de faire tourner le boîtier 1 sans se soucier d'un décalage de l'indicateur des minutes 7 lors d'un changement de fuseau horaire. Ainsi, pour choisir d'afficher l'heure d'un fuseau précis, il suffit de faire pivoter le premier boîtier 1 par rapport au deuxième boîtier 10, en le manipulant à la main jusqu'à ce que le fuseau horaire soit positionné à midi sur le premier boîtier 1 . Les douze trous permettent de faire pivoter le premier boîtier heure par heure, et ce quel que soit le sens de rotation, en correspondance avec les fuseaux horaires qui diffèrent en général d'une heure entre eux, et la montre peut alors permettre de lire l'heure dans les différents fuseaux horaires affichés par l'indicateur. According to a particularly advantageous aspect of the invention, the hour indicator 6 is formed by a transparent disk supporting a triangle 60 indicating the current time on the dial which bears no numeral for the hours. Another disc forming the minute indicator 7 is mounted on the hour disc 6, the minutes disc having an opening 70 showing the current minutes on the dial, the minutes being this time displayed on the dial 3 digitally . Thus, the dial 3 comprises two portions, one without numerical indication for the hours, and the other with numerical indications for the minutes. Such a display mode makes it possible to rotate the housing 1 without worrying about a shift of the minute indicator 7 during a time zone change. Thus, to choose to display the time of a specific time zone, simply rotate the first housing 1 relative to the second housing 10, manipulating it by hand until the time zone is positioned at noon on the first case 1. The twelve holes make it possible to rotate the first housing hour by hour, whatever the direction of rotation, in correspondence with the time zones which generally differ from one hour between them, and the watch can then make it possible to read the time in the different time zones displayed by the indicator.
Comme illustré aux figures 3a et 3b, le deuxième boîtier 10 comprend, au niveau de chaque corne 1 10, une noyure 1 1 1 pour permettre le passage de la couronne 5 lors de la rotation du premier boîtier 1 dans le deuxième boîtier 10. De plus, le deuxième boîtier est ajouré sur ses parties latérales, supérieure et inférieure, de manière à pouvoir accéder à la couronne 5 facilement. As illustrated in FIGS. 3a and 3b, the second housing 10 comprises, at the level of each horn 1 10, a recess 11 to allow the passage of the ring 5 during the rotation of the first housing 1 in the second housing 10. more, the second housing is perforated on its side portions, upper and lower, so as to access the crown 5 easily.
Si le porteur de la montre souhaite connaître l'heure actuelle dans un fuseau horaire précis il lui suffit de tourner le premier boîtier dans le sens horaire ou antihoraire. Par exemple, dans le cas où le porteur se trouve sur le fuseau horaire de Londres 100 comme illustré aux figure 4a et 4b, et souhaite afficher l'heure courante à Moscou, il lui suffit d'amener l'indication du fuseau horaire Moscou 101 à midi sur le premier boîtier 1 , ce qui correspond à trois décalages et déplace la couronne 5 de trois heures à 6 heures. Le passage de l'heure courante d'un fuseau horaire à un autre est donc grandement facilité et simplifié grâce à cette montre. If the wearer of the watch wants to know the current time in a specific time zone, he simply turns the first housing in the direction hourly or counterclockwise. For example, in the case where the carrier is in the time zone of London 100 as shown in Figures 4a and 4b, and wishes to display the current time in Moscow, it is sufficient to bring the time zone indication Moscow 101 at noon on the first housing 1, which corresponds to three offsets and moves the crown 5 from three hours to 6 hours. The passage of the current time from one time zone to another is therefore greatly facilitated and simplified with this watch.
Pour toute modification de l'heure, par exemple pour le passage de l'heure d'été à l'heure d'hiver ou inversement, le porteur doit se positionner sur le fuseau horaire de Londres et ensuite choisir le fuseau horaire pour y afficher l'heure du fuseau choisi. For any change in the time, for example to change from daylight saving time to winter time or vice versa, the bearer must position himself on the London time zone and then choose the time zone to display the chosen time of the spindle.
Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme du métier. Of course, the present invention is not limited to the illustrated example but is susceptible of various variants and modifications that will occur to those skilled in the art.
