It is possible to know if it is daytime or night-time, to know where the sunrise or sunset is currently taking place, but it is not possible to know when the sunrise and sunset will occur. sunset in a precise position on Earth.

Le brevet EP2911013A1 cite le précédent ( DE7014354 ) et revendique une particularité dans la présentation de la sphère qui permet de la placer dans une montre bracelet, en plaçant la sphère dans un puits, et proposant des solutions pour permettre une lecture des indications bien que seule une moitié de la sphère est visible. Le mécanisme présenté et revendiqué ne permet pas d'indiquer les heures de levers et de couchers de soleil relatif à une position précise sur Terre.The patent EP2911013A1 quote the previous one ( DE7014354 ) and claims a particularity in the presentation of the sphere that allows to place it in a wristwatch, placing the sphere in a well, and proposing solutions to allow a reading of the indications although only half of the sphere is visible.

Le brevet US 3,366,800 décrit un programmateur horaire fonctionnant sur une base annuelle comportant un mécanisme de compensation annuelle des variations d'heures de lever et de coucher du soleil (visible sur sa figure 12). Ce mécanisme comporte une roue annuelle portant une came réalisée sous la forme d'une gorge et destinée à corriger la position d'un levier en fonction de la période de l'année. Ce document précise que la position de la gorge sur la roue annuelle est fonction de la latitude et que chaque roue avec sa gorge est réalisée pour une latitude donnée.The patent US 3,366,800 describes an hourly scheduler operating on an annual basis including an annual compensation mechanism for variations in sunrise and sunset times (visible in Figure 12). This mechanism comprises an annual wheel carrying a cam made in the form of a groove and intended to correct the position of a lever according to the time of year. This document specifies that the position of the groove on the annual wheel is a function of the latitude and that each wheel with its groove is made for a given latitude.

Tous ont un point commun, ils sont dimensionnés et construits de façon à permettre le calcul des phénomènes astronomiques désignés précédemment par rapport à une position précise sur Terre, telle une coordonnée géographique, ou une zone restreinte sur Terre, telle une ville, une région géographique ou administrative, un pays, ou un hémisphère. Les indications calculées par la montre sont alors erronées si elles sont appliquées à un point de vue sur Terre qui ne se trouve pas dans la zone qui a été prévue dans la conception et la fabrication de la montre. Aucun moyen ne permet de modifier ni la zone géographique de référence, ni les paramètres de l'heure civile par rapport à laquelle des indications temporelles des phénomènes astronomiques sont affichés, ce qui est le principal inconvénient de tous les mécanismes de l'art antérieur. Ces mécanismes utilisent généralement des cames fixées rigidement sur des roues réalisant une rotation en une année, comme revendiqué explicitement dans le brevet EP1962154A2 et la modification des paramètres de référence nécessiterait le remplacement ou la modification de la géométrie de la came ce qu'aucun mécanisme ne permet à ce jour.They all have one thing in common: they are sized and constructed to allow the calculation of previously designated astronomical phenomena with respect to a specific position on Earth, such as a geographical coordinate, or a restricted area on Earth, such as a city, a geographical region or administrative, a country, or a hemisphere. The indications calculated by the watch are then erroneous if they are applied to a point of view on Earth that is not in the area that was planned in the design and manufacture of the watch. There is no way to modify either the reference geographical area or the parameters of the civil time against which indications temporal astronomical phenomena are displayed, which is the main disadvantage of all the mechanisms of the prior art. These mechanisms generally use cams fixed rigidly on rotating wheels in one year, as explicitly claimed in the patent. EP1962154A2 and the modification of the reference parameters would require the replacement or the modification of the cam geometry that no mechanism allows today.

Le brevet US 2,121,585 décrit également un programmateur horaire annuel comprenant une roue annuelle portant une came agencée pour assurer un ajustement de la programmation en fonction de la période de l'année. Ce document prévoit que la came puisse être déplacée suivant une direction transversale à celle de son axe de rotation pour régler le programmateur en fonction de la latitude à laquelle il est utilisé. L'ajustement de la position de la came doit être réalisé en intervenant directement sur le mécanisme, en dévissant un écrou permettant de verrouiller la came dans sa position de service.The patent US 2,121,585 also discloses an annual time scheduler comprising an annual wheel carrying a cam arranged to provide programming adjustment according to the time of year. This document provides that the cam can be moved in a direction transverse to that of its axis of rotation to adjust the programmer according to the latitude at which it is used. Adjusting the position of the cam must be achieved by intervening directly on the mechanism, by unscrewing a nut to lock the cam in its operating position.

Ce qui est utile est donc de remédier au principal inconvénient de l'art antérieur expliqué précédemment en permettant de corriger ou de prendre en compte dans le calcul de phénomènes astronomiques des paramètres variables, qui influencent le résultat. Ce qui est utile est donc une solution de couplage des informations temporelles et des indications astronomiques qui s'effectue sans train planétaire.What is useful is therefore to overcome the main disadvantage of the prior art explained above by making it possible to correct or take into account in the calculation of astronomical phenomena variable parameters which influence the result. What is useful is therefore a coupling solution of time information and astronomical indications which is carried out without planetary gear.

Un des buts de la présente invention est de remédier au principal inconvénient de l'art antérieur expliqué précédemment en permettant de corriger ou de prendre en compte dans le calcul de phénomènes astronomiques des paramètres variables, qui influencent le résultat, tels que la position sur Terre par rapport à laquelle ils sont observés, ou les paramètres de l'heure civile de référence utilisée pour les calculer ou les afficher.One of the aims of the present invention is to remedy the main disadvantage of the prior art explained above by making it possible to correct or take into account in the calculation of astronomical phenomena variable parameters which influence the result, such as the position on Earth relative to which they are observed, or the parameters of the reference calendar hour used to calculate or display them.

Ceci afin d'assurer que la position du point de contact du palpeur 3 sur la came 2, dans toute position fixe de la roue annuelle 1, reste inchangée quelle que soit la position de la commande de came 4. Ledit palpeur 3 coopérant avec des mécanismes supplémentaires de calcul ou avec des dispositifs d'affichage.Device for calculation mechanism consisting of an annual wheel 1 which rotates a cam 2 which is positioned in translation by a cam control 4, said cam 2 cooperating with a probe 3 which is guided in translation or pseudo-translation. This is to ensure that the position of the contact point of the feeler 3 on the cam 2, in any fixed position of the annual wheel 1, remains unchanged regardless of the position of the cam control 4. Said probe 3 cooperating with additional computing mechanisms or with display devices.

En référence aux figures 1-3 , le dispositif pour mécanisme de calcul se compose d'une roue annuelle 1 qui est entrainée par le mouvement d'horlogerie et qui réalise un tour complet en une année. Celle-ci porte une came 2 et l'entraine en rotation. Ladite came 2 est montée sur la roue annuelle 1 par un dispositif de guidage linéaire par rails, glissière ou rainure dans l'une ou l'autre des deux pièces. Ladite came 2 peut se translater librement, mais sa position lui est imposée par la commande de came 4 qui l'immobilise dans une position fixe dépendant de sa propre position. Ceci soit par l'intermédiaire d'un doigt 5 dans la commande de came 4 qui est dans une rainure 6 de la came 2, soit par le même principe mais avec la rainure dans la commande de came 4 et le doigt dans la came 2. La roue annuelle 1 et la commande de came 4 sont pilotées par deux mécanismes, et la position de la came 2 dépend de la position angulaire de la roue annuelle 1 et de la commande de came 4.With reference to figures 1-3 , the device for calculation mechanism consists of an annual wheel 1 which is driven by the watch movement and which performs a complete revolution in one year. This carries a cam 2 and causes it to rotate. Said cam 2 is mounted on the annual wheel 1 by a rail linear guide device, slide or groove in one or other of the two parts. Said cam 2 can translate freely, but its position is imposed by the cam control 4 which immobilizes it in a fixed position depending on its own position. This is via a finger 5 in the cam control 4 which is in a groove 6 of the cam 2, or by the same principle but with the groove in the cam control 4 and the finger in the cam 2 The annual wheel 1 and the cam control 4 are driven by two mechanisms, and the position of the cam 2 depends on the angular position of the annual wheel 1 and the cam control 4.

En référence aux figures 1 - 5 , un palpeur 3 est en contact avec la came 2. Le palpeur 3 est guidé en translation ou en pseudo-translation par des systèmes de rails 7, 8, disposés soit sur le bâti 15, soit sur le palpeur 3 lui-même. Le palpeur 3 est solidaire avec une crémaillère 13. Un dispositif de rainures 9 peut également être employé pour le guidage linéaire, les rainures 9 pouvant être tantôt sur le bâti 15 ou sur le palpeur 3 lui-même. Un autre moyen consiste à avoir plusieurs paires de lames flexibles 11 qui relient le palpeur 3 au bâti 15, ou suivant le même principe mais avec plusieurs paires de bras rigides 12 articulés à leurs extrémités. La translation du palpeur 3 lui permet de rester en contact avec la même partie de la came 2 quel que soit le réglage de la commande de came 4 et donc de rendre les deux paramètres qui sont la position de la roue annuelle 1 et de la commande de came 4 indépendants sur le résultat du calcul qui est la position du palpeur 3.With reference to Figures 1 - 5 , a feeler 3 is in contact with the cam 2. The probe 3 is guided in translation or in pseudo-translation by rail systems 7, 8, arranged either on the frame 15 or on the probe 3 itself. The probe 3 is integral with a rack 13. A groove device 9 can also be used for the linear guide, the grooves 9 can be sometimes on the frame 15 or on the probe 3 itself. Another means is to have several pairs of flexible blades 11 which connect the probe 3 to the frame 15, or following the same principle but with several pairs of rigid arms 12 articulated at their ends. The translation of the probe 3 allows it to remain in contact with the same part of the cam 2 regardless of the setting of the cam control 4 and thus to make the two parameters which are the position of the annual wheel 1 and the control of 4 independent cam on the result of the calculation which is the position of the probe 3.

Ce mécanisme peut être employé en particulier pour réaliser des calculs de phénomènes astronomiques, tels que les positions de tous types d'astres vus de la Terre, les heures de passages des astres à des positions définies et les intervalles de temps entre le passage d'un astre d'une position définie à une autre position définie vue de la Terre. La commande de came 4 permet de faire intervenir des paramètres qui influent le résultat des calculs de phénomènes astronomiques tels que la position sur Terre par rapport à laquelle ils sont calculés.This mechanism can be used in particular to perform calculations of astronomical phenomena, such as the positions of all types of bodies seen from the Earth, the hours of passage of the stars at defined positions and the time intervals between the passage of a star from a position defined at another defined position seen from the Earth. The cam control 4 makes it possible to use parameters that influence the result of calculations of astronomical phenomena such as the position on Earth with respect to which they are calculated.

Le palpeur 3 comporte une crémaillère qui coopère avec une roue dentée 14, à partir de laquelle tous types de mécanismes peuvent être inclus pour prendre en compte des paramètres supplémentaires influant le calcul des phénomènes astronomiques et tous types de mécanisme permettant de commander des affichages sous toutes formes. Dans une autre version d'exécution le palpeur 3 porte directement d'une manière solidaire des affichages sous toutes formes.The probe 3 comprises a rack which cooperates with a toothed wheel 14, from which all types of mechanisms can be included to take into account additional parameters. influencing the calculation of astronomical phenomena and all types of mechanism for controlling displays in all forms. In another version of execution the probe 3 directly door solidarity displays in all forms.

La figure 6 montre une version d'exécution avec le palpeur 3 pourvu d'une crémaillère 13' courbe et une roue 14' non-circulaire.The figure 6 shows an execution version with the probe 3 provided with a rack 13 'curve and a wheel 14' non-circular.

La figure 7 est une vue en plan qui montre un cas ou la crémaillère 13" et le pignon 14" sont composés chacun d'une seule dent. Cette solution permet d'éviter des défauts d'engrenages à plusieurs dents, lors du passage d'une dent à l'autre.The figure 7 is a plan view showing a case where the rack 13 "and the pinion 14" are each composed of a single tooth. This solution makes it possible to avoid gear defects with several teeth when passing from one tooth to the other.

La figure 8 montre un exemple d'une possibilité d'emploi de l'invention pour afficher les heures de lever et de coucher du soleil. Le dispositif inventé est relié depuis la roue 14 par un train d'engrenages vers le pignon 26 qui porte l'aiguille 27 qui permet de lire l'heure de lever du soleil par rapport à la graduation 28 du cadran. Le train d'engrenage inclut un train planétaire composé de la couronne 22, de la roue centrale 21, et du châssis 19 qui porte les satellites 20. Ledit train planétaire permet d'inclure dans l'affichage les informations venant de la roue 23 qui entraine la couronne 22 et qui représente la position longitudinale de référence par rapport à laquelle l'affichage de l'heure de lever du soleil est indiqué. Un renvoi 18 transmet le mouvement de la roue 16 vers le châssis 19. Un second renvoi 25 transmet le mouvement depuis une roue 24 solidaire de la roue centrale 21 du train planétaire, vers le pignon 26 qui porte l'aiguille 27. Dans ce cas d'emploi l'invention permet l'affichage du lever du soleil tout en permettant de varier la position longitudinale de référence avec la roue 23 et de modifier la position latitudinale de référence en déplaçant la came 2 par rapport à la roue annuelle 1 par l'action de la commande de came 4. Pour l'indication des heures de coucher du soleil, un même train de rouage peut être utilisé, mais en se connectant sur la roue 17 qui est reliée à la roue 16 et dont son mouvement est inversé. Pour des raisons de clarté cette partie n'a pas été représentée sur la figure 8.The figure 8 shows an example of a possibility of using the invention to display the sunrise and sunset times. The invented device is connected from the wheel 14 by a gear train to the gear 26 which carries the needle 27 which makes it possible to read the sunrise time relative to the graduation 28 of the dial. The gear train includes a planetary gear consisting of the ring gear 22, the central wheel 21, and the frame 19 which carries the satellites 20. Said planetary gear allows to include in the display the information coming from the wheel 23 which causes the crown 22 and which represents the longitudinal reference position with respect to which the display of the sunrise time is indicated. A return 18 transmits the movement of the wheel 16 to the frame 19. A second transmission 25 transmits the movement from a wheel 24 secured to the central wheel 21 of the sun gear, to the pinion 26 which carries the needle 27. In this case use of the invention allows the display of the sunrise while allowing to vary the longitudinal reference position with the wheel 23 and to change the reference latitudinal position by moving the cam 2 relative to the annual wheel 1 by the action of the cam control 4. For the indication of the hours of sunset, the same train can be used, but by connecting to the wheel 17 which is connected to the wheel 16 and whose movement is reversed . For the sake of clarity this part has not been represented on the figure 8 .

La figure 9 montre un autre exemple d'affichage des heures de lever et de coucher du soleil. Cette variante montre des feuilles minces colorées ou transparentes servant comme indicateur du temps.The figure 9 shows another example of displaying sunrise and sunset times. This variant shows thin colored or transparent sheets serving as an indicator of time.

Un des buts de la présente invention est de remédier au principal inconvénient de l'art antérieur expliqué précédemment en permettant de corriger ou de prendre en compte dans le calcul de phénomènes astronomiques des paramètres variables qui influencent le résultat, tels que la position sur Terre par rapport à laquelle ils sont observés, ou les paramètres de l'heure civile de référence utilisée pour les calculer ou les afficher.One of the aims of the present invention is to remedy the main disadvantage of the prior art explained above by making it possible to correct or take into account in the calculation of astronomical phenomena variable parameters which influence the result, such as the position on Earth by where they are observed, or the parameters of the reference calendar hour used to calculate or display them.

Un autre but de la présente invention est de proposer un nouveau moyen de coupler et de combiner des informations venant de différents mécanismes pour effectuer des calculs qui dépendent de ces diverses entrées.Another object of the present invention is to provide a new means of coupling and combining information from different mechanisms to perform calculations that depend on these various inputs.
