Description

La présente invention concerne un dispositif d'affichage du quantième ainsi que de l'heure de lever du soleil et/ou de l'heure de coucher du soleil, comprenant un disque de quantième de 31 jours, un premier index de quantième agencé pour indiquer un quantième sur ledit disque de quantième, un organe d'affichage de l'heure de lever et/ou de coucher du soleil, un deuxième index agencé pour indiquer l'heure de lever du soleil et/ou un troisième index agencé pour indiquer l'heure de coucher du soleil sur l'organe d'affichage de l'heure de lever et/ou de coucher du soleil. La présente invention concerne également une pièce d'horlogerie comprenant un tel dispositif d'affichage.The present invention relates to a device for displaying the date as well as the time of sunrise and / or the time of sunset, comprising a 31-day date disc, a first date index arranged to indicate a date on said date disc, a device for displaying the time of sunrise and / or sunset, a second index arranged to indicate the time of sunrise and / or a third index arranged to indicate the time of sunrise and / or sunset sunset time on the sunrise and / or sunset time display unit. The present invention also relates to a timepiece comprising such a display device.

Un tel type de dispositif d'affichage est utilisé dans une pièce d'horlogerie comprenant généralement également un cadran principal de 12 heures pour afficher de manière traditionnelle l'heure légale sur ledit cadran principal au moyen d'une aiguille des heures. Le quantième est affiché au moyen d'un guichet ou sur un cadran constitué par un disque de quantième de 31 jours, au moyen d'une aiguille de quantième. Les heures de lever et de coucher du soleil sont affichées généralement sur deux cadrans ou secteurs angulaires gradués au moyen de deux aiguilles ou index respectifs. Ces guichets, cadrans ou secteurs angulaires utilisés pour lire le quantième ainsi que les heures de lever et de coucher du soleil sont généralement répartis sur le cadran principal avec d'autres affichages, chaque aiguille ou index ayant son propre axe de rotation, et chaque information à afficher étant gérée par son propre mécanisme. Les différents mécanismes concentrés du même côté du cadran représentent un certain encombrement, ce qui rend difficile la conception et la construction de ces pièces d'horlogerie appelées grandes complications. De plus, les cadrans ou secteurs angulaires supplémentaires présentent l'inconvénient d'alourdir et de charger le cadran principal en informations, rendant difficile la lecture de l'heure. Ils peuvent être positionnés au dos de la pièce d'horlogerie afin de libérer de l'espace sur le cadran principal et de l'espace sous le cadran principal pour les mécanismes associés. Mais de ce fait, les informations ne seront pas visibles de l'utilisateur lorsque celui-ci portera au poignet la pièce d'horlogerie.Such a type of display device is used in a timepiece generally also comprising a main 12 hour dial for traditionally displaying legal time on said main dial by means of an hour hand. The date is displayed by means of an aperture or on a dial formed by a 31-day date disc, by means of a date hand. The sunrise and sunset times are generally displayed on two dials or angular sectors graduated by means of two respective hands or indexes. These apertures, dials or angular sectors used to read the date as well as the sunrise and sunset times are generally distributed over the main dial with other displays, each hand or index having its own axis of rotation, and each item of information to display being managed by its own mechanism. The various mechanisms concentrated on the same side of the dial represent a certain bulk, which makes the design and construction of these timepieces called grand complications difficult. In addition, the dials or additional angular sectors have the drawback of weighing down and loading the main information dial, making it difficult to read the time. They can be positioned on the back of the timepiece to free up space on the main dial and space under the main dial for associated mechanisms. But because of this, the information will not be visible to the user when the latter wears the timepiece on the wrist.

En outre, la plupart des pièces d'horlogerie comprenant un dispositif d'affichage des heures de lever et de coucher du soleil ne permettent pas de gérer le changement d'heure été/hiver pour l'affichage des heures de lever et de coucher du soleil. Dans la plupart des cas, le problème est résolu en demandant à l'utilisateur de corriger l'heure légale au moment du changement d'heure en déplaçant l'aiguille des heures au moyen de la tige de mise à l'heure et, après le passage à l'heure d'été, d'ajouter virtuellement une heure aux heures de lever et de coucher du soleil, l'affichage de ces heures restant en réalité toujours à l'heure d'hiver. Certains constructeurs rappellent cette opération en prévoyant une petite inscription sur le cadran d'affichage des heures de lever et de coucher du soleil pour ne pas oublier d'ajouter une heure lorsque l'heure légale est passée à l'heure d'été. Cela signifie que les heures de lever et de coucher du soleil affichées réellement sur leurs organes d'affichage respectifs sont erronées la moitié de l'année, lorsque l'heure légale est passée à l'heure d'été.In addition, most timepieces comprising a device for displaying the times of sunrise and sunset do not make it possible to manage the change of summer / winter time for the display of the sunrise and sunset times. Sun. In most cases, the problem is solved by asking the user to correct the daylight saving time at the time of the time change by moving the hour hand by means of the time setting rod and after the change to summer time, to add virtually one hour to the sunrise and sunset times, the display of these times still in reality always in winter time. Some manufacturers recall this operation by providing a small inscription on the display dial for the hours of sunrise and sunset so as not to forget to add a time when legal time has changed to summer time. This means that the sunrise and sunset times actually displayed on their respective displays are incorrect for half of the year, when daylight saving time has changed to daylight saving time.

Pour résoudre ce problème, la demande CH 712 493 propose un mécanisme permettant de modifier une information horaire liée à un phénomène astronomique, telle que l'heure de lever ou de coucher du soleil, en fonction de l'heure d'été et de l'heure d'hiver et/ou d'une longitude ou d'un fuseau horaire. Ledit mécanisme comprend une commande bistable actionnée manuellement et agencée pour n'agir que sur un indicateur de l'heure de lever ou de coucher du soleil, géré par ailleurs par une roue commandée par des mécanismes de calcul astronomique, en provoquant un déplacement d'une heure dudit indicateur de l'heure de lever ou de coucher du soleil lors du changement d'heure été/hiver, ainsi que sur un indicateur de commande montrant les deux positions stables été/hiver de ladite commande. Ce document ne donne aucune information sur la correction de l'heure légale au moment du changement d'heure été/hiver lorsque la commande bistable est utilisée.To solve this problem, the request CH 712 493 proposes a mechanism making it possible to modify time information linked to an astronomical phenomenon, such as the time of sunrise or sunset, as a function of summer time and winter time and / or of a longitude or a time zone. Said mechanism comprises a bistable control actuated manually and arranged to act only on an indicator of the time of sunrise or sunset, managed moreover by a wheel controlled by astronomical calculation mechanisms, causing a displacement of a time of said indicator of the hour of sunrise or sunset during the summer / winter time change, as well as on a control indicator showing the two stable positions summer / winter of said order. This document does not give any information on the correction of the daylight saving time at the time of the summer / winter time change when the bistable control is used.

Le document CH690516 divulgue un affichage du quantième par un index coopérant avec une échelle à 31 positions et l'affichage du lever et du coucher du soleil sur une échelle ouverte et séparée de celle du quantième.The document CH690516 discloses a date display by an index cooperating with a 31-position scale and the display of sunrise and sunset on an open scale separate from that of the date.

En référence aux figures 1 et 2, la présente invention concerne un dispositif d'affichage 1 d'une pièce d'horlogerie permettant d'afficher le quantième, c'est-à-dire la date du jour, sur un disque de quantième 8 au moyen d'un premier index de quantième 14 agencé pour indiquer un quantième sur ledit disque de quantième 8. Le disque de quantième 8 est de 31 jours, c'est-à-dire qu'il comporte 31 graduations réparties régulièrement sur sa circonférence.With reference to figures 1 and 2 , the present invention relates to a display device 1 of a timepiece making it possible to display the date, that is to say the current date, on a date disc 8 by means of a first index date 14 arranged to indicate a date on said date disc 8. The date disc 8 is 31 days old, that is to say it has 31 graduations distributed regularly over its circumference.

Le dispositif d'affichage 1 comprend également un organe d'affichage de l'heure de lever et/ou de coucher du soleil 8, un deuxième index 10, tel qu'une aiguille pour afficher l'heure de lever du soleil sur l'organe d'affichage 8 et un troisième index 12, tel qu'une aiguille pour afficher l'heure de coucher du soleil.The display device 1 also comprises a member for displaying the time of sunrise and / or sunset 8, a second index 10, such as a hand for displaying the time of sunrise on the screen. display member 8 and a third index 12, such as a hand for displaying the sunset time.

Le dispositif d'affichage 1 permet également d'afficher l'heure légale sur un organe d'affichage de l'heure légale 2, tel qu'un cadran, au moyen d'un quatrième index de l'heure légale 4, tel qu'une aiguille. Les minutes sont affichées de manière traditionnelle sur l'organe d'affichage de l'heure légale 2 au moyen d'un index des minutes 6, tel qu'une aiguille. Les index 4 et 6 sont entrainés par le mouvement de la pièce d'horlogerie de manière connue en soi, afin d'afficher l'heure légale par exemple sur 12h. Notamment, le quatrième index de l'heure légale 4 est porté par une roue des heures 5, qui peut être par exemple une roue des heures à fuseaux. Il est également possible de prévoir un mécanisme d'entrainement des index 4 et 6 approprié pour avoir un affichage de l'heure légale sur 24h.The display device 1 also makes it possible to display the legal time on a legal time display member 2, such as a dial, by means of a fourth legal time index 4, such as 'a needle. The minutes are traditionally displayed on the legal time display unit 2 by means of a minute index 6, such as a hand. The indexes 4 and 6 are driven by the movement of the timepiece in a manner known per se, in order to display the legal time for example at 12 o'clock. In particular, the fourth index of legal time 4 is carried by an hour wheel 5, which may for example be a time zone hour wheel. It is also possible to provide a mechanism for driving the indexes 4 and 6 suitable for displaying the legal time over 24 hours.

L'organe d'affichage de l'heure de lever et/ou de coucher du soleil 8, les deuxième et troisième index 10 et 12 sont positionnés du même côté que le quatrième index de l'heure légale 4. De plus, les deuxième et troisième index 10 et 12 ainsi que le quatrième index de l'heure légale 4 sont de préférence concentriques, leurs axes de rotation respectifs étant confondus. De même, l'organe d'affichage de l'heure légale 2 et l'organe d'affichage de l'heure de lever et/ou de coucher du soleil 8 sont de préférence concentriques.The display member for the sunrise and / or sunset time 8, the second and third indexes 10 and 12 are positioned on the same side as the fourth index for legal time 4. In addition, the second and third index 10 and 12 as well as the fourth index of legal time 4 are preferably concentric, their respective axes of rotation being the same. Likewise, the display device for the legal time 2 and the display device for the sunrise and / or sunset time 8 are preferably concentric.

Conformément à l'invention, l'organe d'affichage de l'heure de lever et/ou de coucher du soleil est constitué par le disque de quantième de 31 jours 8, le deuxième index 10 et/ou le troisième index 12 étant agencé(s) pour pivoter ou tourner de 11,6° par heure par rapport au disque de quantième 8. Cela signifie que, d'une manière avantageuse, la lecture des heures de lever et de coucher du soleil se fait sur le disque de quantième 8 au moyen des deuxième et troisième index 10 et 12 en utilisant, comme chiffres et nombres relatifs aux heures de lever et de coucher du soleil, les chiffres et nombres représentés sur le disque de quantième 8 pour indiquer par ailleurs le quantième. Ainsi, le disque de quantième 8 est avantageusement utilisé pour indiquer à la fois les heures de lever et de coucher du soleil au moyen des deuxième et troisième index 10 et 12 ainsi que les jours au moyen du premier index de quantième 14, concentrique au deuxième et troisième index 10 et 12 ainsi qu'au quatrième index de l'heure légale 4. Ledit premier index de quantième 14 est agencé pour indiquer le quantième sur le disque de quantième 8 au moyen d'un mécanisme de quantième comprenant de manière classique notamment une roue entraineuse de quantième 16 entrainée par la roue des heures 5 d'un tour par 24h et une roue ou étoile de quantième 18 à 31 dents portant le premier index de quantième 14, maintenue par son sautoir de quantième 20 et le ressort de sautoir de quantième associé 21, et entrainée en rotation par un doigt de quantième 22 solidaire de la roue entraineuse de quantième 16, d'un pas par jour, lors du changement de quantième. Un tel mécanisme de quantième est connu de l'homme du métier et ne nécessite pas ici une plus ample description.According to the invention, the device for displaying the time of sunrise and / or sunset is formed by the 31-day date disc 8, the second index 10 and / or the third index 12 being arranged (s) to pivot or rotate by 11.6 ° per hour relative to the date disc 8. This means that, in an advantageous manner, the reading of the times of sunrise and sunset is made on the date disc 8 by means of the second and third indexes 10 and 12 using, as figures and numbers relating to the times of sunrise and sunset, the figures and numbers represented on the date disc 8 to further indicate the date. Thus, the date disc 8 is advantageously used to indicate both the times of sunrise and sunset by means of the second and third indexes 10 and 12 as well as the days by means of the first date index 14, concentric with the second and third index 10 and 12 as well as the fourth index of legal time 4. Said first date index 14 is arranged to indicate the date on the date disc 8 by means of a date mechanism comprising of in a conventional manner, in particular a date driving wheel 16 driven by the hours wheel 5 of one revolution per 24 hours and a date wheel or star 18 to 31 teeth carrying the first date index 14, held by its date jumper 20 and the associated date jumper spring 21, and driven in rotation by a date finger 22 integral with the date driving wheel 16, one step per day, during the date change. Such a date mechanism is known to those skilled in the art and does not require a fuller description here.

Pour faciliter la lecture des heure de lever et coucher du soleil sur le disque de quantième 8, il est possible de prévoir sur ledit disque de quantième 8 deux secteurs gradués 24, 25, portant une graduation additionnelle propre aux heures de lever et de coucher du soleil et délimités par les heures minimale et maximale de lever et coucher du soleil en utilisant les chiffres correspondant aux quantièmes de même valeur. Par exemple le secteur des heures de lever de soleil 24 compris entre 4h et 10h peut être indiqué par des graduations ajoutées sur le disque de quantième 8 entre les quantièmes 4 et 10. Le secteur des heures de coucher du soleil 25 compris entre 16h et 22h peut être indiqué par des graduations ajoutées sur le disque de quantième 8 entre les quantièmes 16 et 22.To facilitate the reading of the sunrise and sunset times on the date disc 8, it is possible to provide on said date disc 8 two graduated sectors 24, 25, bearing an additional graduation specific to the sunrise and sunset times. sun and delimited by the minimum and maximum hours of sunrise and sunset using the figures corresponding to dates of the same value. For example, the sunrise hours sector 24 between 4h and 10h can be indicated by graduations added on the date disc 8 between dates 4 and 10. The sunset hours sector 25 between 16h and 22h can be indicated by graduations added on the date disc 8 between the dates 16 and 22.

Il est bien évident que selon les variantes de réalisation, seul l'un des deuxième et troisième index 10, 12 peut être mis en œuvre si l'on souhaite afficher seulement les heures de lever ou les heures de coucher du soleil.It is obvious that according to the variant embodiments, only one of the second and third indexes 10, 12 can be implemented if it is desired to display only the times of sunrise or the times of sunset.

Les deuxième et troisième index 10 et 12 sont entrainés par un mécanisme d'entrainement gérant les heures de lever et de coucher du soleil de manière annuelle au moyen de cames présentant une forme de manière à décrire les variations des heures de lever et de coucher du soleil au cours de l'année. De tels mécanismes gérant les heures de lever et de coucher du soleil dans une pièce d'horlogerie, telle qu'une montre-bracelet, sont connus de l'homme du métier et ne nécessitent pas ici une plus ample description.The second and third indexes 10 and 12 are driven by a drive mechanism managing the times of sunrise and sunset on an annual basis by means of cams having a shape so as to describe the variations in the times of sunrise and sunset. sun during the year. Such mechanisms managing the sunrise and sunset times in a timepiece, such as a wristwatch, are known to those skilled in the art and do not require further description here.

Un tel mécanisme de gestion des heures de lever et de coucher du soleil est décrit par exemple dans la demande EP 18152022 de la demanderesse. Ce mécanisme comprend un palpeur des heures de lever du soleil portant une denture formant une crémaillère qui engrène avec une roue portant une aiguille indicatrice des heures de lever du soleil correspondant au deuxième index 10 et un palpeur des heures de coucher du soleil portant une denture formant une crémaillère qui engrène avec une roue portant une aiguille indicatrice des heures de coucher du soleil correspondant au troisième index 12. Les palpeurs sont mobiles en translation et maintenus en appui respectivement contre une came des heures de lever du soleil et contre une came des heures de coucher du soleil par un système à guidage flexible.Such a mechanism for managing the times of sunrise and sunset is described for example in the request EP 18152022 of the plaintiff. This mechanism comprises a sunrise hours feeler carrying a toothing forming a rack which meshes with a wheel carrying a hand indicating the sunrise hours corresponding to the second index 10 and a sunset hours feeler carrying a toothing forming a rack which meshes with a wheel carrying a hand indicating the hours of sunset corresponding to the third index 12. The probes are movable in translation and held in support respectively against a cam for the hours of sunrise and against a cam for the hours of sunrise. sunset by a flexible guiding system.

Toutefois, dans le cadre de la présente invention, le mécanisme gérant les heures de lever et de coucher du soleil entrainant les deuxième et troisième index 10 et 12 est conçu pour que les deuxième et/ou troisième index 10 et 12 pivotent de 11.6° par heure (c'est-à-dire 360/31) par rapport au disque de quantième 8. L'homme du métier horloger sait comment calculer le profil des cames de lever et/ou de coucher du soleil pour obtenir une vitesse de rotation des deuxième et/ou troisième index 10 et 12 de 11.6° par heure par rapport au disque de quantième 8. Par exemple, dans le cas du mécanisme gérant les heures de lever et de coucher du soleil décrit dans la demande EP 18152022 de la demanderesse, l'homme du métier sait définir le profil de la came des heures de lever du soleil de sorte que la différence entre le rayon maximal et le rayon minimal de la came des heures de lever du soleil corresponde à la longueur du déplacement rectiligne du palpeur des heures de lever du soleil calculé en fonction de l'angle parcouru par le deuxième index 10 entre l'heure minimale de lever du soleil et l'heure maximale de lever du soleil rapporté à un affichage de 31 heures sur 360°. De même, le profil de la came des heures de coucher du soleil est défini de sorte que la différence entre le rayon maximal et le rayon minimal de la came des heures de coucher du soleil corresponde à la longueur du déplacement rectiligne du palpeur des heures de coucher du soleil calculé en fonction de l'angle parcouru par le troisième index 12 entre l'heure minimale de coucher du soleil et l'heure maximale de coucher du soleil rapporté à un affichage de 31 heures sur 360°.However, in the context of the present invention, the mechanism managing the hours of sunrise and sunset driving the second and third indexes 10 and 12 is designed so that the second and / or third indexes 10 and 12 are pivoted by 11.6 ° by hour (that is to say 360/31) relative to the date disk 8. Those skilled in the watchmaking art know how to calculate the profile of the sunrise and / or sunset cams in order to obtain a speed of rotation of the sunrise and / or sunset cams. second and / or third index 10 and 12 of 11.6 ° per hour with respect to the date disc 8. For example, in the case of the mechanism managing the sunrise and sunset times described in the request EP 18152022 for the applicant, those skilled in the art know how to define the profile of the sunrise time cam so that the difference between the maximum radius and the minimum radius of the sunrise time cam corresponds to the length of the displacement rectilinear sensor of the hours of sunrise calculated as a function of the angle traversed by the second index 10 between the minimum time of sunrise and the maximum time of sunrise in relation to a display of 31 hours over 360 ° . Likewise, the profile of the sunset time cam is set so that the difference between the maximum radius and the minimum radius of the sunset time cam corresponds to the length of the rectilinear movement of the sunset time probe. sunset calculated as a function of the angle traveled by the third index 12 between the minimum sunset time and the maximum sunset time referred to a 31-hour display over 360 °.
