Abstract

The watch comprises a dial (10), an hour hand (11), a minute hand (12), a bi-rotational stepping motor (14) connected to these hands through gears (13) a current source (16) and an electronic circuit for controlling the stepping motor. The circuit has means for storing a time-based item of information. The watch is equipped with means for displaying this time-based information. For this purpose, the motor which drives the hands is controlled in accelerated motion to bring the seconds hand (11) into a position corresponding to this time-based information in less than one revolution of the hand. The invention is suitable for use in conventional wrist watches with birotational stepping motor.

Description

La présente invention concerne un procédé pour afficher sur un cadran de montre, en particulier de montre-bracelet à affichage analogique et comportant un seul moteur électrique pour entraîner les aiguilles, au moins une information à base horaire mémorisée.The present invention relates to a method for displaying on a watch dial, in particular a wristwatch with analog display and comprising a single electric motor for driving the hands, at least one information based on stored time.

Elle concerne également une montre, en particulier une montre-bracelet à affichage analogique et comportant un seul moteur électrique, du type pas-à-pas à double sens de rotation pour entraîner les aiguilles, des moyens pour mémoriser au moins une information à base horaire et des moyens pour afficher sur un cadran cette information mémorisée.It also relates to a watch, in particular a wristwatch with analog display and comprising a single electric motor, of the stepping type with two directions of rotation for driving the hands, means for memorizing at least one time-based information and means for displaying this stored information on a dial.

On connaît déjà des montres du type montre-bracelet pourvues d'une sonnerie et d'une mémoire pour mémoriser l'heure d'enclenchement prévue de la sonnerie. L'utilisateur est fréquemment amené à contrôler cette heure mémorisée, en particulier s'il s'agit de l'heure du réveil. Le seul moyen pour connaître l'heure mémorisée est de l'afficher sur le cadran de la montre. Pour ce faire, les montres connues utilisent tout simplement leurs aiguilles des heures et des minutes, se déplaçant simultanément en mode accéléré.There are already known watches of the wristwatch type provided with a ringing device and with a memory for memorizing the scheduled time for the ringing to start. The user is frequently required to check this memorized time, in particular if it is the alarm time. The only way to find out the stored time is to display it on the watch face. To do this, known watches simply use their hour and minute hands, simultaneously moving in accelerated mode.

Dans les montres courantes équipées d'un moteur conventionnel, la durée du déplacement simultané des deux aiguilles peut être relativement longue. En effet, s'il est huit heures, et si l'heure mémorisée d'enclenchement de la sonnerie du réveil est par exemple sept heures dix, l'aiguille des heures doit faire un tour presque complet, et l'aiguille des minutes doit simultanément effectuer onze tours complets. Le temps nécessité par cette manoeuvre est important, d'autant plus que le retour s'effectue selon le même processus. En moyenne, le nombre de tours que doit effectuer l'aiguille des minutes est de douze quel que soit le sens de marche de ces aiguilles, à savoir la marche avant, la marche arrière ou alternativement les deux sens de marche.In current watches equipped with a conventional motor, the duration of the simultaneous movement of the two hands can be relatively long. In fact, if it is eight o'clock, and if the memorized time for activating the alarm bell is for example ten minutes past seven, the hour hand must make an almost complete turn, and the minute hand must simultaneously perform eleven full turns. The time required for this maneuver is important, especially since the return takes place according to the same process. On average, the number of revolutions that the minute hand must make is twelve regardless of the direction of travel of these hands, namely forward, reverse or alternately the two directions of travel.

Dans la pratique, avec les montres connues ayant un moteur d'entraînement unique actionnant les aiguilles des minutes et des heures on procède de la façon suivante, à partir de l'indication normale de l'heure et de la minute:In practice, with known watches having a single drive motor actuating the minute and hour hands, the procedure is as follows, starting from the normal indication of the hour and the minute:

― mise en route du moteur en marche accélérée entraînant une rotation rapide de l'aiguille des minutes et plus lente de l'aiguille des heures,- starting the engine in accelerated mode, leading to a rapid rotation of the minute hand and a slower rotation of the hour hand,

― arrêt du moteur lorsque l'heure mémorisée est affichée. Dans ce cas l'heure et la minute sont affichées simultanément,- engine stop when the stored time is displayed. In this case the hour and the minute are displayed simultaneously,

― pendant un laps de temps, il est possible de lire l'heure mémorisée et éventuellement de la modifier en actionnant le moteur,- for a period of time, it is possible to read the memorized time and possibly modify it by operating the motor,

― retour en marche accélérée à l'indication normale de l'heure et de la minute.- return to accelerated operation at the normal indication of the hour and the minute.

Dans les montres plus sophistiquées comportant un moteur spécial pouvant entraîner les aiguilles à une vitesse fortement accélérée, ce temps, bien que raccourci, reste relativement long et gênant pour l'utilisateur. En outre, les moteurs de ce type étant fort coûteux, seules les montres de prix élevé peuvent en être équipées, ce qui limite fortement leur diffusion.In more sophisticated watches comprising a special motor capable of driving the hands at a strongly accelerated speed, this time, although shortened, remains relatively long and inconvenient for the user. In addition, since motors of this type are very expensive, only high-priced watches can be fitted with them, which greatly limits their distribution.

La présente invention se propose de pallier les différents inconvénients mentionnés ci-dessus, en développant un procédé et en réalisant une montre équipée pour afficher très rapidement une information mémorisée sans recourir à des moyens techniques sophistiqués.The present invention proposes to overcome the various drawbacks mentioned above, by developing a method and by making a watch equipped to display memorized information very quickly without resorting to sophisticated technical means.

Ce but est atteint par le procédé selon l'invention, caractérisé en ce que l'on déplace les aiguilles de la montre en faisant tourner le moteur à vitesse accélérée pour amener, en moins d'un tour, l'aiguille la plus rapide dans une position indiquant l'information à base horaire mémorisée, et en ce que l'on ramène les aiguilles dans leur position normale à vitesse accélérée.This object is achieved by the method according to the invention, characterized in that the hands of the watch are moved by turning the motor at accelerated speed to bring, in less than one revolution, the fastest hand in a position indicating the stored time base information, and in that the hands are returned to their normal position at accelerated speed.

Selon un mode de réalisation avantageux, on maintient l'aiguille la plus rapide dans cette position pendant un intervalle de temps prédéterminé.According to an advantageous embodiment, the fastest needle is kept in this position for a predetermined time interval.

Selon un mode de réalisation préféré, on fait osciller l'aiguille la plus rapide autour de ladite position pendant un intervalle de temps prédéterminé.According to a preferred embodiment, the fastest needle is oscillated around said position for a predetermined time interval.

Selon une forme de réalisation avantageuse, on utilise l'aiguille des minutes de la montre.According to an advantageous embodiment, the minute hand of the watch is used.

Selon une variante, on utilise l'aiguille des secondes de la montre.According to a variant, the seconds hand of the watch is used.

Selon un autre mode de réalisation, on utilise une aiguille supplémentaire de la montre qui n'est ni l'aiguille des minutes, ni celle des secondes.According to another embodiment, an additional watch hand is used which is neither the minute hand nor the second hand.

L'information à base horaire affichée est avantageusement l'heure d'enclenchement de la sonnerie d'un réveil.The time-based information displayed is advantageously the time when the alarm rings.

Selon un autre mode de réalisation, l'information à base horaire est l'heure d'un lieu prédéterminé situé dans un autre fuseau horaire.According to another embodiment, the time-based information is the time of a predetermined place located in another time zone.

Selon un mode de réalisation également avantageux, on procède en au moins deux phases, une première phase au cours de laquelle l'aiguille indique l'heure, et une seconde phase au cours de laquelle l'aiguille indique les minutes. Ce mode opératoire permet de réaliser un affichage très précis.According to an equally advantageous embodiment, one proceeds in at least two phases, a first phase during which the hand indicates the hour, and a second phase during which the hand indicates the minutes. This operating mode makes it possible to produce a very precise display.

La montre selon l'invention, telle que définie ci-dessus, est caractérisée en ce qu'elle comporte un circuit électronique de commande du moteur d'entraînement des aiguilles, agencé pour commander sur demande le déplacement accéléré des aiguilles et pour amener, en moins d'un tour, l'aiguille la plus rapide dans la position indiquant l'information à base horaire mémorisée, et pour ramener ces aiguilles à vitesse accélérée dans leur position normale.The watch according to the invention, as defined above, is characterized in that it comprises an electronic circuit for controlling the needle drive motor, arranged to control the accelerated movement of the hands on request and to bring, in less than one revolution, the fastest hand in the position indicating the stored time base information, and to return these needles at accelerated speed to their normal position.

Selon un mode de réalisation avantageux, le circuit électronique de commande est agencé pour'maintenir l'aiguille la plus rapide dans cette position pendant un intervalle de temps prédéterminé.According to an advantageous embodiment, the electronic control circuit is arranged to maintain the fastest needle in this position for a predetermined time interval.

Selon un mode de réalisation préféré, le circuit électronique de commande est agencé pour faire osciller l'aiguille la plus rapide autour de ladite position pendant un intervalle de temps prédéterminé.According to a preferred embodiment, the electronic control circuit is arranged to oscillate the fastest needle around said position for a predetermined time interval.

Selon diverses variantes, l'aiguille utilisée peut être l'aiguille des minutes, l'aiguille des secondes ou une aiguille supplémentaire de la montre qui n'est ni l'aiguille des minutes, ni celle des secondes.According to various variants, the hand used can be the minute hand, the second hand or an additional watch hand which is neither the minute hand nor the second hand.

Dans le cas où la montre est équipée d'une sonnerie, du type sonnerie de réveil, l'information à base horaire mémorisée est avantageusement l'heure d'enclenchement de la sonnerie.In the case where the watch is equipped with a ring, of the alarm ring type, the information based on the stored time base is advantageously the time of activation of the ring.

Dans le cas où la montre comporte un circuit électronique agencé pour calculer l'heure correspondant à l'heure affichée, dans un lieu prédéterminé situé dans un autre fuseau horaire, l'information horaire mémorisée est avantageusement cette heure calculée audit lieu prédéterminé.In the case where the watch comprises an electronic circuit arranged to calculate the time corresponding to the displayed time, in a predetermined place located in another time zone, the stored time information is advantageously this time calculated at said predetermined place.

Pour permettre de réaliser un affichage extrêmement précis de l'information horaire mémorisée, la montre peut comporter un circuit électronique de commande agencé pour déplacer ladite aiguille en au moins deux phases, une première phase au cours de laquelle l'aiguille indique l'heure et une seconde phase au cours de laquelle l'aiguille indique les minutes de ladite information mémorisée.To enable an extremely precise display of the stored time information to be produced, the watch may include an electronic control circuit arranged to move said hand in at least two phases, a first phase during which the hand indicates the time and a second phase during which the hand indicates the minutes of said stored information.

Plusieurs informations à base horaire peuvent être affichées simultanément ou successivement.Several time-based information can be displayed simultaneously or successively.

La présente invention sera mieux comprise en référence à la description d'un exemple de réalisation et du dessin annexé dans lequel:The present invention will be better understood with reference to the description of an exemplary embodiment and the appended drawing in which:

La figure unique représente une vue schématique d'une forme de réalisation préférée de la montre selon l'invention.The single figure shows a schematic view of a preferred embodiment of the watch according to the invention.

En référence à la figure, la montre selon l'invention comporte essentiellement un cadran 10, une aiguille des heures 11, et une aiguille des minutes 12, respectivement entraînées via un train d'engrenages 13 par un moteur pas-à-pas 14 à double sens de rotation. Un circuit électronique 15 assure la commande du moteur 14. Une source de courant électrique 16 est directement connectée au circuit électronique 15 et au moteur 14. Le circuit électronique 15 comporte une entrée 17 permettant l'introduction de l'information à base horaire à mémoriser et diverses autres entrées 18 destinées à intervenir sur différentes fonctions de la montre. Dans la pratique, ces entrées peuvent être matérialisées par des touches de fonction montées sur le boîtier de la montre ou par une couronne ou par tout autre dispositif connu en soi (non représenté).Referring to the figure, the watch according to the invention essentially comprises a dial 10, an hour hand 11, and a minute hand 12, respectively driven via a gear train 13 by a stepping motor 14 to double direction of rotation. An electronic circuit 15 controls the motor 14. An electric current source 16 is directly connected to the electronic circuit 15 and to the motor 14. The electronic circuit 15 has an input 17 allowing the introduction of time-based information to be memorized and various other inputs 18 intended to intervene on different functions of the watch. In practice, these inputs can be embodied by function keys mounted on the watch case or by a crown or by any other device known per se (not shown).

Lorsque l'utilisateur veut introduire en mémoire des informations à base horaire telles que par exemple l'heure d'enclenchement de la sonnerie 19 du réveil, il manipule de façon appropriée le dispositif (non représenté) connecté à l'entrée 17 du circuit électronique 15. Par la suite, s'il veut connaître l'information horaire qui a été mémorisée par le circuit électronique 15, il manipule de façon appropriée une des touches de fonction correspondant à l'une des entrées 18 du circuit électronique 15. Suite à cette intervention, le circuit électronique transmet au moteur d'entraînement 14 des impulsions rapides qui ont pour effet de déplacer de préférence l'aiguille des minutes dans une position indiquant, sur le cadran 10 de la montre, au moins approximativement l'heure correspondant à cette information horaire mémorisée. Lorsque l'aiguille des minutes se déplaçant à vitesse accélérée est arrivée dans la position souhaitée, elle oscille de préférence deux ou trois fois autour de cette position, ce qui fournit à l'utilisateur une indication visuelle, en général suffisamment précise, de l'information horaire mémorisée, puis retourne dans sa position normale à vitesse accélérée.When the user wants to enter time-based information in memory such as, for example, the time at which the alarm 19 rings, he appropriately handles the device (not shown) connected to the input 17 of the electronic circuit. 15. Subsequently, if he wants to know the time information which has been memorized by the electronic circuit 15, he appropriately manipulates one of the function keys corresponding to one of the inputs 18 of the electronic circuit 15. Following this intervention, the electronic circuit transmits to the drive motor 14 rapid pulses which have the effect of preferably moving the minute hand in a position indicating, on the dial 10 of the watch, at least approximately the hour corresponding to this stored time information. When the minute hand traveling at an accelerated speed has arrived in the desired position, it preferably oscillates two or three times around this position, which provides the user with a visual indication, in general sufficiently precise, of the memorized time information, then returns to its normal position at accelerated speed.

Comme mentionné précédemment, on pourrait également utiliser d'autres aiguilles telles que par exemple l'aiguille des secondes 20 ou une aiguille supplémentaire 21 prévue à cet effet. L'utilisation de l'aiguille des minutes a pour avantage de fournir une indication particulièrement précise du fait qu'un pas correspond à quatre minutes, ce qui permet d'obtenir une précision d'affichage suffisante.As mentioned previously, other needles could also be used such as for example the second hand 20 or an additional needle 21 provided for this purpose. The advantage of using the minute hand is that it provides a particularly precise indication that a step corresponds to four minutes, which makes it possible to obtain sufficient display precision.

Selon un autre mode de réalisation, l'affichage pourrait être effectué en deux phases:

  • ― une première phase au cours de laquelle l'aiguille des heures indique effectivement l'heure de l'information à base horaire mémorisée, et
  • ― une seconde phase au cours de laquelle l'aiguille des heures indique les minutes de l'information à base horaire mémorisée.
According to another embodiment, the display could be carried out in two phases:
  • A first phase during which the hour hand effectively indicates the time of the stored time-based information, and
  • - a second phase during which the hour hand indicates the minutes of the stored time-based information.

Dans ce cas, l'information fournie, tout en restant extrêmement rapide, est aussi précise que celle que l'on obtient avec les moyens conventionnels décrits précédemment.In this case, the information provided, while remaining extremely fast, is as precise as that obtained with the conventional means described above.

Comme mentionné ci-dessus, l'information à base horaire n'est pas limitée à l'heure d'enclenchement d'une sonnerie de réveil. Cette information à base horaire pourrait également être l'heure calculée en un point quelconque du globe situé dans un fuseau horaire différent de celui dans lequel se trouve l'utilisateur de la montre. Dans ce cas, le circuit électronique mémorise le décalage horaire.As mentioned above, the time-based information is not limited to the time of activation of a wake-up ring. This time-based information could also be the time calculated at any point on the globe situated in a time zone different from that in which the user of the watch is located. In this case, the electronic circuit memorizes the time difference.

En outre, en prévoyant un nombre suffisant d'entrées du circuit électronique 15 et un nombre approprié de touches de fonctions, on pourrait généraliser le système de telle manière que l'on puisse afficher plusieurs informations horaires mémorisées. Le circuit électronique est alors conçu pour permettre la mémorisation simultanée ou successive de différentes informations à base horaire.In addition, by providing a sufficient number of inputs to the electronic circuit 15 and an appropriate number of function keys, one could generalize the system so that one can display several stored time information. The electronic circuit is then designed to allow simultaneous or successive storage of different information on a time basis.

La présente invention n'est pas limitée aux formes de réalisations décrites mais peut s'étendre à d'autres modes de réalisation et à différentes variantes évidentes pour l'homme de l'art.The present invention is not limited to the embodiments described but may extend to other embodiments and to various variants obvious to those skilled in the art.
