Description

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne plus particulièrement une pièce d'horlogerie comportant un affichage de l'heure d'au moins deux fuseaux horaires. Des montres de ce type sont bien connues de l'homme du métier. Elles permettent à son porteur de connaître simultanément l'heure de deux lieux différents sur la planète. On connaît ainsi des montres munies de deux aiguilles des heures, affichant les temps de deux lieux différents.The present invention relates to the field of watchmaking. It relates more particularly to a timepiece having a display of the time of at least two time zones. Watches of this type are well known to those skilled in the art. They allow its wearer to simultaneously know the time of two different places on the planet. Thus, watches are known with two hour hands, displaying the times of two different places.

Des montres de ce type comprennent :

  • un premier dispositif d'affichage muni d'un premier organe d'affichage de l'heure d'un temps correspondant à un premier fuseau horaire,
  • un deuxième dispositif d'affichage muni d'un deuxième organe d'affichage de l'heure d'un temps correspondant à un deuxième fuseau horaire,
  • un organe de liaison reliant cinématiquement le premier au deuxième organe d'affichage,
  • un mécanisme de correction agencé de manière à pouvoir, dans un premier mode, modifier en synchronisme la position des premier et deuxième organes d'affichage, et dans un deuxième mode modifier le deuxième organe d'affichage uniquement.
Watches of this type include:
  • a first display device provided with a first display member of the time of a time corresponding to a first time zone,
  • a second display device provided with a second display member for the time of one time corresponding to a second time zone,
  • a link member kinematically connecting the first to the second display member,
  • a correction mechanism arranged so as to be able, in a first mode, to change in synchronism the position of the first and second display members, and in a second mode to modify the second display member only.

Dans la plupart des cas, les organes d'affichage sont des aiguilles. Ainsi, dans le document EP 1336907 , l'affichage est réalisé au moyen d'un premier cadran et d'aiguilles affichant l'heure locale et formant le premier organe d'affichage, et des petits cadrans affichant les heures d'autres fuseaux horaires et formant le deuxième organe d'affichage. Une telle solution peut conduire à des situations gênantes, du fait que les heures de jour ou de nuit ne sont pas différenciées.In most cases, the display members are needles. So, in the document EP 1336907 , the display is made by means of a first dial and hands showing the local time and forming the first display member, and small dials displaying the hours of other time zones and forming the second organ of display. Such a solution can lead to troublesome situations, because the hours of day or night are not differentiated.

Pour pallier cet inconvénient, le document US 2005/0180265 , dispose d'un second organe d'affichage formé d'une aiguille effectuant un tour en vingt-quatre heures. Avec une telle solution, la différentiation du jour et de la nuit se fait de manière tout à fait claire. Malgré cela, la lecture de l'heure reste difficile, du fait que les échelles de lectures ne sont pas les mêmes, pour une aiguille, le midi se trouvant au haut, et pour l'autre au bas du cadran.To overcome this drawback, the document US 2005/0180265 , has a second display member formed of a needle performing a turn in twenty-four hours. With such a solution, the differentiation of day and night is made quite clear. In spite of this, reading the time remains difficult, because the scales of readings are not the same, for a needle, the midi being at the top, and for the other at the bottom of the dial.

Le but de la présente invention est permettre une appréciation plus simple de l'heure dans un deuxième fuseau horaire. Ce but est atteint grâce au fait que l'organe de liaison qui relie le premier au deuxième dispositif d'affichage est dimensionné de manière à assurer un rapport égal à 1/7n entre les périodes du premier et du deuxième organe, n étant un nombre entier. De la sorte, le deuxième organe d'affichage présente une période de une semaine. Il peut donc afficher le jour de la semaine, permettant ainsi de vérifier non seulement le moment de la journée, mais encore le jour courant dans ce deuxième fuseau horaire.The object of the present invention is to allow a simpler appreciation of the time in a second time zone. This object is achieved by virtue of the fact that the connecting member which connects the first to the second display device is dimensioned so as to ensure a ratio equal to 1 / 7n between the periods of the first and second members, where n is a number whole. In this way, the second display member has a period of one week. It can therefore display the day of the week, allowing to check not only the time of the day, but also the current day in this second time zone.

De manière avantageuse, le deuxième organe d'affichage comporte une aiguille portée par un mobile de l'organe de liaison, lequel est agencé de manière à ce que l'aiguille effectue un tour en sept jours.Advantageously, the second display member comprises a needle carried by a mobile of the connecting member, which is arranged so that the needle performs a turn in seven days.

Afin de rendre la lecture de l'information aussi aisée que possible, la pièce d'horlogerie comporte, en outre, un cadran. De plus, le deuxième dispositif d'affichage comprend des indications relatives au jour de la semaine portées par ce cadran, ainsi que des index disposés sur le cadran et définissant une échelle de temps en regard de ces indications.In order to make the reading of the information as easy as possible, the timepiece comprises, in addition, a dial. In addition, the second display device includes indications relating to the day of the week carried by this dial, as well as indexes arranged on the dial and defining a time scale opposite these indications.

En variante, le deuxième dispositif d'affichage comporte un disque muni d'indications relatives au jour de la semaine et d'index de temps divisant le jour en plusieurs unités, portés sur ce disque. En outre, l'organe de liaison est agencé de manière à faire avancer ce disque à une fréquence au moins égale au temps compris entre deux de ces index, typiquement inférieur ou égal à une heure.Alternatively, the second display device comprises a disk provided with indications relating to the day of the week and time index dividing the day into several units, carried on this disk. In addition, the connecting member is arranged to advance the disk at a frequency at least equal to the time between two of these indexes, typically less than or equal to one hour.

Avantageusement, les index sont au moins de deux types différentiés par leur aspect, permettant de mieux percevoir les temps de travail et de repos.Advantageously, the indexes are at least two types differentiated by their appearance, allowing better perception of working time and rest.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée à titre d'exemple et faite en référence au dessin dans lequel :

  • La figure 1 montre le cadran d'une pièce d'horlogerie selon l'invention,
  • La figure 2 illustre, vu de dessus, un mécanisme de correction et un organe de liaison équipant la pièce d'horlogerie de la figure 1, et
  • Les figures 3 et 4 montrent respectivement, en coupe, l'organe de liaison et une partie de ce mécanisme.
The invention will be better understood on reading the description which follows, given by way of example and with reference to the drawing in which:
  • FIG. 1 shows the dial of a timepiece according to the invention,
  • FIG. 2 illustrates, seen from above, a correction mechanism and a connecting member equipping the timepiece of FIG. 1, and
  • Figures 3 and 4 show respectively, in section, the connecting member and a part of this mechanism.

La pièce d'horlogerie représentée sur la figure 1 comporte, de manière classique, un cadran 10, une aiguille des heures 12 effectuant une tour en douze heures, et une aiguille des minutes 14 effectuant un tour en une heure. Elle comprend, en outre, une aiguille complémentaire 16 portant par un mobile qui effectue un tour en sept jours.The timepiece shown in Figure 1 comprises, in a conventional manner, a dial 10, an hour hand 12 performing a turn in twelve hours, and a minute hand 14 performing a turn in one hour. It further comprises a complementary needle 16 carrying a mobile which performs a turn in seven days.

Le cadran 10 est muni d'indications 18 des jours de la semaine, disposées régulièrement à sa périphérie. Une échelle 20 comportant cent soixante huit index, soit autant que la semaine comporte d'heures, est placée en regard des indications 18, à raison de vingt-quatre index par jour.The dial 10 is provided with indications 18 of the days of the week, arranged regularly on its periphery. A scale of one hundred and sixty-eight indexes, that is to say as many as the week has hours, is placed opposite the indications 18, at the rate of twenty-four indexes per day.

Dans cette pièce d'horlogerie, l'heure locale est donc affichée de manière classique. La lecture de l'information relative au deuxième fuseau horaire permet de déterminer le jour et la période de la journée en cours. La précision de lecture de l'heure affichée n'est donc pas aussi bonne que dans les pièces d'horlogerie mentionnées plus haut, mais un simple coup d'oeil sur l'aiguille 16, et sa position en regard des indications 18, permet de déterminer si le moment est propice pour contacter une personne. Ainsi, pour faciliter la lecture, les index compris entre neuf heures et dix-sept heures, puis ceux de dix-sept à vingt et une heures pourraient avantageusement être différentiés des index de nuit, par leur couleur ou par leur forme.In this timepiece, the local time is thus displayed in a conventional manner. Reading the second time zone information determines the current day and time of the day. The reading accuracy of the displayed time is therefore not as good as in the timepieces mentioned above, but a glance at the needle 16, and its position opposite the indications 18, allows to determine if the time is right to contact a person. Thus, to facilitate reading, the indexes between nine hours and seventeen hours, then those of seventeen to twenty-one hours could advantageously be differentiated from the night indexes, by their color or by their shape.

La pièce d'horlogerie décrite ci-dessus est en outre munie, de manière classique, d'une couronne de mise à l'heure 22. Cette couronne 22 commande un mécanisme agencé de manière à ce que, en position tirée, une rotation de celle-ci permet de corriger les informations affichées. Plus précisément, une rotation dans le sens horaire fait tourner les aiguilles 12, 14 et 16, dans le sens horaire, alors qu'une rotation en sens inverse ne fait tourner que les aiguilles 12 et 14, dans le sens anti-horaire. Cette manipulation est rendue possible grâce aux caractéristiques que présente le mouvement équipant cette pièce d'horlogerie, et plus particulièrement celles illustrées aux figures 2 à 4. De la sorte, une correction dans le sens horaire permet de modifier les deux informations de manière synchronisée, alors de qu'une rotation dans l'autre sens permet de décaler les informations.The timepiece described above is furthermore conventionally provided with a time-setting ring 22. This ring 22 controls a mechanism arranged in such a way that, in the pulled-out position, a rotation of it corrects the displayed information. Specifically, a clockwise rotation rotates the needles 12, 14 and 16, clockwise, while a rotation in the opposite direction turns only the needles 12 and 14, in the counter-clockwise direction. This manipulation is made possible by the characteristics of the movement equipping this timepiece, and more particularly those illustrated in FIGS. 2 to 4. In this way, a correction in the clockwise direction makes it possible to modify the two pieces of information synchronously, then a rotation in the other direction can shift the information.

Comme le montrent les figures 2 à 4, la pièce d'horlogerie selon l'invention comporte un module complémentaire disposé sur un mouvement de base dont seuls des composants du rouage de minuterie sont représentés au dessin. Ce module comprend une platine 24 destinée à être fixée sur le mouvement de base.As shown in Figures 2 to 4, the timepiece according to the invention comprises a complementary module disposed on a base movement of which only components of the clockwork are shown in the drawing. This module comprises a plate 24 intended to be fixed on the base movement.

Le mouvement de base comporte une chaussée 26 (figures 3 et 4) portant l'aiguille des minutes 14 et une roue à canon 28 portant l'aiguille des heures 12. La chaussée 26 entraîne la roue à canon 28 par l'intermédiaire d'une roue de minuterie 29.The basic movement comprises a roadway 26 (FIGS. 3 and 4) carrying the minute hand 14 and a cannon wheel 28 carrying the hour hand 12. The roadway 26 drives the cannon wheel 28 via a timer wheel 29.

Un mobile 30 est monté pivotant sur le canon de la roue 28, au moyen d'une douille 32 chassée sur ce canon. Ce mobile comporte une roue 30a munie, à sa périphérie, de dents de loup, et un pignon 30b. Un ressort 33 est interposé entre la roue 28 et le mobile 30, assurant entre eux une liaison à friction.A mobile 30 is pivotally mounted on the barrel of the wheel 28, by means of a sleeve 32 driven on the barrel. This mobile comprises a wheel 30a provided, at its periphery, with wolf teeth, and a pinion 30b. A spring 33 is interposed between the wheel 28 and the mobile 30, providing between them a friction connection.

La platine 24 porte un mobile 34 comportant une roue 34a engrenant avec le pignon 30b, et un pignon 34b. Une roue 36 est montée pivotante sur le canon de la roue 28, en appui contre la douille 32, et qui porte l'aiguille 16. Le mobile 34 est entraîné, par sa roue 34a qui engrène avec le pignon 30b, alors que son pignon 34a fait tourner la roue 36.The plate 24 carries a mobile 34 having a wheel 34a meshing with the pinion 30b, and a pinion 34b. A wheel 36 is pivotally mounted on the barrel of the wheel 28, bearing against the sleeve 32, and which carries the needle 16. The mobile 34 is driven by its wheel 34a which meshes with the pinion 30b, while its pinion 34a rotates the wheel 36.

Un cliquet de retenue 38 est monté pivotant sur la platine 24 (figure 2). Il est maintenu contre la denture de la roue 30 au moyen d'un ressort 40.A retaining pawl 38 is pivotally mounted on the plate 24 (Figure 2). It is held against the toothing of the wheel 30 by means of a spring 40.

Le mécanisme tel qu'il vient d'être décrit fonctionne de la manière suivante. Le mouvement de base, qui peut aussi bien être de type à quartz que mécanique, fait tourner, par son rouage de finissage, la chaussée 26, laquelle entraîne en rotation la minuterie 29. Cette dernière engrène avec la roue à canon 28 qui fait tourner, par l'intermédiaire du ressort de friction 33, la roue 30a et le pignon 30b. La roue 34a, qui engrène avec le pignon 30b est entraînée en rotation et, avec elle, le pignon 30b et la roue 36. Les roues et pignons sont nombrés de manière à ce que la roue à canon fasse un tour en douze heures, la roue 34 un tour en vingt-quatre heures et la roue 36 un tour en cent soixante huit heures, ou sept jours.The mechanism as just described works as follows. The basic movement, which may be of both quartz and mechanical type, rotates, by its finishing gear, the roadway 26, which rotates the timer 29. The latter meshes with the wheel wheel 28 which rotates through the friction spring 33, the wheel 30a and the pinion 30b. The wheel 34a, which meshes with the pinion 30b, is rotated and, with it, the pinion 30b and the wheel 36. The wheels and pinions are numbered so that the cannon wheel makes a turn in twelve hours. wheel 34 a turn in twenty-four hours and wheel 36 a turn in one hundred and sixty eight hours, or seven days.

Pour effectuer une correction, l'utilisateur actionne la couronne 22 en position tirée. En la tournant dans le sens horaire, il fait tourner la minuterie 29, par l'intermédiaire d'un renvoi non représenté, et par elle, la roue à canon 28 et la chaussée 26 qui tourne à friction sur la roue de grande moyenne du rouage de finissage. La roue à canon fait tourner, par friction, le mobile 30, lequel entraîne le mobile 34 et la roue 36. De la sorte, toutes les aiguilles sont déplacées.To make a correction, the user actuates the ring 22 in the pulled position. By turning it clockwise, it turns the timer 29, via a not shown reference, and by it, the wheel 28 and the raceway 26 which rotates on the wheel of high average of finishing gear. The barrel wheel rotates, by friction, the mobile 30, which drives the mobile 34 and the wheel 36. In this way, all the needles are moved.

Si l'utilisateur fait tourner la couronne 22 en sens inverse, le cliquet 38 retient la roue 30 qui est alors bloquée. De la sorte, seuls la roue à canon 28 et la chaussée 26 sont tournées, ce qui permet de corriger la position des aiguilles 12 et 14, sans changer la position de l'aiguille 16.If the user rotates the ring 22 in the opposite direction, the pawl 38 retains the wheel 30 which is then blocked. In this way, only the gun wheel 28 and the roadway 26 are turned, which makes it possible to correct the position of the needles 12 and 14, without changing the position of the needle 16.

La pièce d'horlogerie qui a été décrite n'est qu'un mode de réalisation parmi d'autres. Le mécanisme de correction pourrait présenter de nombreuses variantes. Il est ainsi possible de munir la pièce d'horlogerie d'un poussoir qui lorsqu'il est activé, fait tourner le mobile 34 et avec lui la roue 36 et l'aiguille 16. Dans ce cas, la friction devrait se faire entre le pignon 30b et la roue 30a, de manière à ce que le cliquet 38 retienne cette dernière, tout en permettant le déplacement de la seule aiguille 16.The timepiece that has been described is only one embodiment among others. The correction mechanism could have many variations. It is thus possible to provide the timepiece with a pusher that when activated, rotates the mobile 34 and with it the wheel 36 and the needle 16. In this case, the friction should be between the pinion 30b and the wheel 30a, so that the pawl 38 retains the latter, while allowing the movement of the single needle 16.

Les organes d'affichage pourraient aussi être différents. Ainsi, les indications 18 et l'échelle 20 pourraient être portés par un disque effectuant un tour en une semaine. Ce disque peut être placé sous le cadran, lequel comporte une fenêtre et n'affiche que les informations apparaissant au travers de cette fenêtre. L'organe de liaison, qui permet d'entraîner ce disque à partir du mouvement des mobiles portant les aiguilles 12 et 14, est agencé de manière à ce qu'il avance à raison d'un pas toutes les heures ou toutes les demi-heures. L'heure et le jour du deuxième fuseau horaire se lisent dans la partie centrale du guichet que comporte le cadran. Ce dispositif comporte avantageusement des plages différentiées par leur aspect, permettant de mieux identifier les heures de travail, de loisir et/ou de repos.The display members could also be different. Thus, the indications 18 and the scale 20 could be carried by a disk performing a revolution in one week. This disk can be placed under the dial, which has a window and displays only the information appearing through this window. The connecting member, which allows to drive the disc from the movement of the mobile carrying the needles 12 and 14, is arranged so that it advances by one step every hour or half hours. The time and day of the second time zone are read in the central part of the window that includes the dial. This device advantageously includes ranges differentiated by their appearance, to better identify the hours of work, leisure and / or rest.

Il est également envisageable de prévoir un affichage de type rétrograde, combiné avec un disque des jours, qui sauterait de un pas chaque jour à minuit du deuxième fuseau horaire, en même temps que l'aiguille rétrograde ferait son mouvement de recul. L'aiguille rétrograde se déplacerait d'une extrémité à l'autre du secteur portant l'indication du jour de la semaine. Dans tous les cas, le deuxième organe d'affichage présente une période égale à une semaine, de telle sorte que le rapport entre les périodes du premier et du deuxième organe est égal à 1/14 si l'aiguille des heures fait un tour en douze heures (n est alors égale à 2), 1/7 si elle fait un tour par jour (n est égal à 1).It is also conceivable to provide a retrograde type display, combined with a day drive, which would jump one step each day at midnight of the second time zone, at the same time that the retrograde hand would make its retreat. The retrograde needle would move from one end of the sector to the other, indicating the day of the week. In all cases, the second display member has a period equal to one week, so that the ratio between the periods of the first and the second member is equal to 1/14 if the hour hand makes a turn in twelve hours (n is then equal to 2), 1/7 if it makes one turn per day (n equals 1).

De manière avantageuse, mais pas obligatoire, les organes d'affichages sont concentrique, leur centre étant confondu avec le centre du cadran.Advantageously, but not required, the display members are concentric, their center coinciding with the center of the dial.
