Abstract
Description
A l'heure actuelle, il existe sur le marché des montres multifonctions analogiques à aiguilles comportant plusieurs moteurs pas-à-pas entraînant indépendamment plusieurs trains de rouages. Dans la version la plus simple, deux moteurs entraînent deux aiguilles, mais on peut également avoir trois, quatre, cinq moteurs entraînant chacun une, voir plusieurs aiguilles, de même que des combinaisons avec des affichages digitaux. Il en va ainsi, par exemple, avec les mouvements 251.262 et 251.272 commercialisés déjà depuis plusieurs années par la maison ETA à Grenchen (Suisse), de même que dans le mouvement décrit dans le brevet EP A O 247.520.At present, there are on the market analog multifunction watches with hands having several stepping motors independently driving several gear trains. In the simplest version, two motors drive two hands, but you can also have three, four, five motors each driving one, or even several needles, as well as combinations with digital displays. This is the case, for example, with movements 251,262 and 251,272 already marketed for several years by the house ETA in Grenchen (Switzerland), as well as in the movement described in patent EP A O 247,520.
Ces configurations permettent d'afficher simultanément ou successivement plusieurs fonctions annexes en sus des fonctions horaires classiques, par exemple les heures, minutes et secondes d'une fonction chronographe.These configurations make it possible to display simultaneously or successively several additional functions in addition to the conventional time functions, for example the hours, minutes and seconds of a chronograph function.
Une autre des fonctions annexes les plus répandues est sans doute la date. Cette fonction de quantième peut être simple, semi-perpétuelle, ou perpétuelle. Dans ce dernier cas, il est nécessaire de programmer en plus du jour, le mois et l'année bissextile. Par ailleurs, la date peut être complétée par l'affichage des phases de lune.Another of the most common ancillary functions is undoubtedly the date. This date function can be simple, semi-perpetual, or perpetual. In the latter case, it is necessary to program in addition to the day, the month and the leap year. In addition, the date can be completed by displaying the moon phases.
L'une des principales difficultés est d'afficher clairement le nombre de jours du mois qui peut varier de 28 à 31, ce qui suppose, particulièrement dans le cas d'un affichage analogique à aiguille, une graduation spéciale souvent peu facile à lire comme on peut le constater dans le brevet susmentionné où le quantième est affiché par une petite aiguille et un cadran gradué de 1 à 31.One of the main difficulties is to clearly display the number of days of the month which can vary from 28 to 31, which supposes, particularly in the case of an analog needle display, a special graduation often not easy to read as it can be seen in the aforementioned patent where the date is displayed by a small hand and a dial graduated from 1 to 31.
D'autre part, on connaît des montres à un seul moteur, mécanique ou électrique, dans lesquelles la date est affichée constamment par deux mobiles, l'un de ces mobiles indiquant les dizaines et l'autre les unités.On the other hand, watches with a single motor, mechanical or electric, are known, in which the date is constantly displayed by two mobiles, one of these mobiles indicating the tens and the other the units.
Dans certaines de ces montres les deux mobiles sont constitués par deux aiguilles coaxiales de longueur différente qui coopèrent avec deux graduations circulaires concentriques inscrites sur un cadran. Le document CH-A-394 958 décrit plusieurs formes d'exécution d'une montre de ce genre.In some of these watches, the two mobiles consist of two coaxial hands of different length which cooperate with two concentric circular graduations inscribed on a dial. Document CH-A-394 958 describes several embodiments of a watch of this kind.
Dans d'autres montres, comme celle qui est décrite par exemple dans le document CH-A-2 262, les deux mobiles sont des anneaux dont l'un porte les chiffres des dizaines et l'autre les chiffres des unités. Dans ce cas, la date est visible à travers un guichet du cadran.In other watches, such as that described for example in document CH-A-2 262, the two mobiles are rings, one of which carries the tens figures and the other the units figures. In this case, the date is visible through a window on the dial.
Indépendamment de cela, on connaît aussi des montres à plusieurs moteurs dans lesquelles l'une au moins des aiguilles qui servent à indiquer l'heure normale peut être utilisée pour afficher temporairement et sur commande une ou plusieurs autres informations. C'est le cas par exemple pour la montre qui est décrite dans le document FR-A-2 605 118 et dans laquelle l'aiguille de secondes peut être amenée à afficher simultanément le mois et l'année bissextile.Independently of this, there are also known watches with several engines in which at least one of the hands which serve to indicate the standard time can be used to temporarily display and on command one or more other pieces of information. This is the case for example for the watch which is described in the document FR-A-2 605 118 and in which the second hand can be caused to simultaneously display the month and leap year.
Enfin, on connaît également des montres comme celle qui est décrite dans le document CH-A-170 801, qui comportent deux cadrans juxtaposés, associés chacun à une seule aiguille, l'un de ces cadrans servant à afficher les heures et l'autre les minutes.Finally, we also know watches like the one described in document CH-A-170 801, which have two juxtaposed dials, each associated with a single hand, one of these dials being used to display the hours and the other minutes.
Cela dit, la présente invention concerne une montre avec affichage particulièrement lisible de la date, cet affichage pouvant être utilisé momentanément pour l'affichage du mois ou de l'heure sur 24 heures. Cette montre avec dispositif de quantième comportant plusieurs mobiles d'affichage entraînés complètement indépendamment les uns des autres par plusieurs moteurs pas à pas et des moyens électroniques agencés de manière à afficher la date est caractérisée par le fait que la date est affichée au moyen de deux graduations placées sur deux cadrans distincts, la dizaine étant affichée sur un premier cadran par un premier desdits mobiles d'affichage entraîné par un premier moteur, et l'unité sur un second cadran par un deuxième desdits mobiles d'affichage entraîné par un deuxième moteur.That said, the present invention relates to a watch with a particularly legible display of the date, this display being able to be used momentarily for displaying the month or the hour over 24 hours. This watch with date device comprising several display mobiles driven completely independently of each other by several stepping motors and electronic means arranged to display the date is characterized in that the date is displayed by means of two graduations placed on two separate dials, the ten being displayed on a first dial by a first of said display mobiles driven by a first motor, and the unit on a second dial by a second of said display mobiles driven by a second motor .
La figure 1 représente à titre d'exemple une montre selon l'invention avec affichage du jour et de l'année bissextile.Figure 1 shows by way of example a watch according to the invention with display of the day and leap year.
La figure 2 représente schématiquement à titre d'exemple une partie des moyens électroniques d'une montre selon l'invention.FIG. 2 schematically shows, by way of example, part of the electronic means of a watch according to the invention.
La figure 3 représente à titre d'exemple une montre selon l'invention à laquelle ont été ajouté un affichage du mois et des phases de lune.FIG. 3 shows by way of example a watch according to the invention to which a display of the month and moon phases has been added.
La figure 4 représente à titre d'exemple une combinaison particulière d'un mobile d'affichage où l'aiguille à été remplacée par un disque portant une graduation.FIG. 4 shows by way of example a particular combination of a display mobile where the needle has been replaced by a disc carrying a graduation.
Sur la figure 1, il est représenté à titre d'exemple une montre comportant des aiguilles d'heure (1) et de minute (2), ainsi que deux aiguilles (3 et 4) travaillant sur deux cadrans distincts à 2 heures et à 10 heures pour l'affichage de fonctions annexes. Ces quatre aiguilles sont indépendantes les unes des autres et forment autant de mobiles d'affichage entraînés chacun au travers d'un train de rouages par leur propre moteur pas-à-pas, la position de chacune de ces aiguilles étant gérée directement par le circuit électronique.In FIG. 1, there is shown by way of example a watch comprising hour (1) and minute (2) hands, as well as two hands (3 and 4) working on two separate dials at 2 o'clock and at 10 hours for the display of additional functions. These four needles are independent of each other and form as many display mobiles each driven through a train of cogs by their own stepping motor, the position of each of these needles being managed directly by the circuit. electronic.
Dans la configuration donnée à la figure 1, l'aiguille (3), qui fait 24 pas par tour, affiche simultanément la dizaine de jours et l'année bissextile sur un cadran. Ce cadran porte une double graduation formée de 4 secteurs numérotés de 0 à 3 (6), chaque secteur comportant une graduation interne de quatre positions (7). L'aiguille (3) indique donc simultanément la dizaine de jours dans le secteur correspondant, soit 2 dans le cas de la figure 1, et l'année bissextile sur la graduation interne du secteur. L'aiguille (4) indique pour sa part l'unité des jours sur une graduation de 0 à 9 (8). Ainsi, dans le cas de la figure 1, on affiche le 23ème jour du mois dans une année bissextile. Cette disposition particulière de l'affichage du jour sur deux mobiles d'affichage permet une lecture particulièrement sûre.In the configuration given in FIG. 1, the hand (3), which takes 24 steps per revolution, simultaneously displays the ten days and the leap year on a dial. This dial carries a double graduation formed by 4 sectors numbered from 0 to 3 (6), each sector having an internal graduation of four positions (7). The hand (3) therefore simultaneously indicates the ten days in the corresponding sector,
Pour réaliser la programmation d'un quantième perpétuel, il est également nécessaire de pouvoir programmer le mois. Il est sans autre possible dans le cas de la figure 1, d'afficher momentanément le mois au moyen des aiguilles (3 et 4) de même manière que le jour, et de programmer celui-ci par des manipulations adéquates des poussoirs (9 et 10). Cependant, il peut être utile d'affichar simultanément tous les paramètres en rapport avec le quantième, lors de la programmation de celui-ci.To program a perpetual calendar, it is also necessary to be able to program the month. It is without other possibility in the case of FIG. 1, to momentarily display the month by means of the hands (3 and 4) in the same way as the day, and to program this one by adequate manipulations of the pushers (9 and 10). However, it can be useful to display all the parameters related to the date simultaneously, when programming the date.
Ceci est possible dans le cas de la figure 1, en mettant la tige de mise à l'heure (11) en position intermédiaire. A ce moment là, les aiguilles d'heure et de minute (1 et 2) viennent afficher le mois sur la graduation des heures. Cette configuration permet d'afficher simultanément le jour, le mois et l'année bissextile lors des opérations de correction du quantième.This is possible in the case of FIG. 1, by putting the time-setting rod (11) in the intermediate position. At that time, the hour and minute hands (1 and 2) display the month on the hour scale. This configuration allows the day, month and leap year to be displayed simultaneously during calendar correction operations.
Nous ne donnerons pas en détail les circuits électroniques associés à ces fonctions, ceux-ci étant déjà connus, mais nous nous concentrerons sur l'affichage du jour, et d'autres paramètres complémentaires sur deux mobiles d'affichages distincts, l'un pour les dizaines et l'autre pour les unités.We will not give details of the electronic circuits associated with these functions, these being already known, but we will focus on the day display, and other additional parameters on two separate display mobiles, one for the tens and one for the units.
La figure 2 représente schématiquement à titre d'exemple le circuit électronique qui gère la position de l'aiguille 3. Ce circuit comporte une table de correspondance (20) reliée d'une part au circuit de comptage des dizaines de jours (21), et d'autre part au compteur des années bissextiles (22). Chacun de ces compteurs a quatre états distincts, ce qui représente 16 combinaisons possibles. La table de correspondance (20) fixe donc 16 positions de l'aiguille (3) correspondant à ces 16 combinaisons possibles, chacune de ces 16 positions correspondant à une position particulière de l'aiguille sur le cadran 5. Cette table de correspondance est reliée à un circuit de positionnement (23) qui gère les 24 positions possibles de l'aiguille (3) sur le cadran et délivre des impulsions au moteur (24) jusqu'à ce que l'aiguille se trouve dans la position donnée par la table de correspondance.FIG. 2 schematically shows by way of example the electronic circuit which manages the position of the
Il est très facile d'utiliser l'aiguille (3) pour afficher d'autres paramètres, tel que, par exemple, la dizaine d'heures pour l'affichage momentané de l'heure sur 24 heures. Il suffit de relier le commutateur (25) à la sortie d'une deuxième table de correspondance (26) reliée elle au compteur de dizaines du compteur d'heures. Nous verrons dans la figure 3 quel usage peut être fait de cette particularité. De même le commutateur (25) pourrait permettre de relier le circuit de positionnement (23) à une troisième table de correspondance reliée au compteur de dizaines du compteur de mois, permettant ainsi l'affichage de la dizaine du mois au moyen de l'aiguille (3).It is very easy to use the hand (3) to display other parameters, such as, for example, the ten hours for the momentary display of the time over 24 hours. It is sufficient to connect the switch (25) to the output of a second correspondence table (26) connected to the tens counter of the hour counter. We will see in Figure 3 what use can be made of this feature. Similarly, the switch (25) could make it possible to connect the positioning circuit (23) to a third correspondence table connected to the tens counter of the month counter, thus allowing the display of the ten months by means of the hand. (3).
Sur la figure 3, il est représenté à titre d'exemple un dispositif de quantième où le mois est affiché de manière permanente par un mobile d'affichage supplémentaire comportant l'aiguille (30) travaillant sur une graduation de 12 (31). Cette disposition permet d'afficher simultanément tous les paramètres d'un quantième perpétuel, soit l'unité des jours au moyen de l'aiguille (4), la dizaine des jours et l'année bissextile au moyen de l'aiguille (3), et le mois au moyen de l'aiguille (30). Selon une configuration similaire à celle décrite à la figure 2, il est possible d'utiliser l'aiguille (30) pour afficher momentanément un deuxième paramètre, soit, dans l'exemple de la figure 3, les phases de lune sur l'élément graphique (32) censé représenter la voûte céleste.In Figure 3, there is shown by way of example a date device where the month is permanently displayed by an additional display mobile comprising the hand (30) working on a scale of 12 (31). This arrangement makes it possible to simultaneously display all the parameters of a perpetual calendar, i.e. the unit of days using the hand (4), the ten days and the leap year by means of the needle (3), and the month by means of the needle (30). According to a configuration similar to that described in FIG. 2, it is possible to use the hand (30) to temporarily display a second parameter, that is, in the example of FIG. 3, the moon phases on the element. graphic (32) supposed to represent the sky.
Comme décrit à la figure 2, il est possible d'utiliser les aiguilles (3 et 4) pour afficher momentanément un autre paramètre que le jour. Il s'agit là en effet d'un affichage d'une capacité de 00 à 39 qui peut être utilisé pour afficher n'importe quel paramètre se situant entre ces limites.As described in Figure 2, you can use the hands (3 and 4) to temporarily display a parameter other than the day. This is indeed a display with a capacity from 00 to 39 which can be used to display any parameter lying between these limits.
Nous avons déjà évoqué la possibilité d'afficher momentanément le mois lors de la correction du quantième. La figure 3 représente plus particulièrement le cas décrit à la figure 2, soit l'affichage momentané de l'heure sur 24 heures lors des opérations de mise à l'heure.We have already mentioned the possibility of temporarily displaying the month when correcting the date. FIG. 3 represents more particularly the case described in FIG. 2, that is the momentary display of the time over 24 hours during the time setting operations.
Sur la figure 3, la mise à l'heure (11) est en position tirée pour permettre la mise à l'heure des aiguilles (1 et 2) au moyen des poussoirs (9 et 10). Pendant cette phase de mise à l'heure, il est intéressant d'afficher l'heure sur 24 heures au moyen des aiguilles (3 et 4), soit les dizaines au moyen de l'aiguille (3) et les unités au moyen de l'aiguille (4), de manière à éviter d'avoir 12 heures de décalage au passage de la date, comme cela arrive fréquemment sur les montres classiques. Ainsi, sur la figure 3, les aiguilles (3 et 4) indiquent 23 heures; il est donc 23h40 et non 11h40.In FIG. 3, the time setting (11) is in the pulled position to allow the setting of the hands (1 and 2) by means of the pushers (9 and 10). During this time setting phase, it is interesting to display the time over 24 hours using the hands (3 and 4), i.e. the tens to by means of the needle (3) and the units by means of the needle (4), so as to avoid having a 12-hour difference in time as the date passes, as frequently happens on conventional watches. Thus, in Figure 3, the hands (3 and 4) indicate 23 hours; it is therefore 11.40 p.m. and not 11.40 a.m.
La figure 4 représente une combinaison particulière d'un mobile d'affichage selon l'invention. En effet, dans les revendications, il a été utilisé ce terme de mobile d'affichage plutôt que celui d'aiguille, car il est possible de remplacer l'aiguille par d'autres systèmes mobiles, comme par exemple un disque gradué se déplaçant par rapport à des éléments graphiques fixes. Sur la figure 4, on voit un tel disque (40) transparent et portant une graduation de 1 à 12 (41) et un cercle représentant la lune (42). Ce disque se déplace sur un décor fond sur fond sombre comportant une zone claire (43). On peut constater que les indications en regard du fond sombre sont pratiquement illisibles, alors que les éléments en regard du fond clair sont parfaitement lisibles. Cette méthode permet d'obtenir des variantes intéressantes et d'afficher le mois, voir le jour, en pseudo-digital.FIG. 4 represents a particular combination of a display mobile according to the invention. In fact, in the claims, this term display mobile has been used rather than that of needle, because it is possible to replace the needle by other mobile systems, such as for example a graduated disc moving by compared to fixed graphic elements. In Figure 4, we see such a disc (40) transparent and carrying a graduation from 1 to 12 (41) and a circle representing the moon (42). This disc moves on a background decoration on a dark background comprising a light area (43). We can see that the indications opposite the dark background are practically illegible, while the elements opposite the light background are perfectly legible. This method makes it possible to obtain interesting variants and to display the month, even the day, in pseudo-digital.
Il est évident que bien d'autres combinaisons selon l'invention sont possible, mais leur description n'apporterait aucun élément supplémentaire pour la compréhension de l'invention.It is obvious that many other combinations according to the invention are possible, but their description would not provide any additional element for understanding the invention.
