Description

La présente invention concerne un dispositif d'affichage de date adaptée à coopérer avec un guichet d'une montre ainsi qu'un procédé de mise en action du dispositif d'affichage.The present invention relates to a date display device adapted to cooperate with a window of a watch and a method of actuating the display device.

Un exemple d'un tel dispositif est donné dans le document EP 1 070 996 .An example of such a device is given in the document EP 1 070 996 .

Les systèmes d'affichage de date dit à grand guichet existant sur des montres, notamment des montres-bracelets, utilisent tous, pour des raisons de place disponible sur les pièces mobiles d'affichage, des guichets doubles ou en paires tels que les dates 1 à 9 de chaque mois se lisent soit 0 - unité, soit espace vide - unité. Cette manière de faire n'est pas très esthétique et il serait souhaitable que l'on puisse avoir un affichage centré dans le guichet aussi bien pour les dates constituées d'un seul chiffre (1 à 9) que pour les dates à deux chiffres (10 à 31).The date display systems said to large existing counter on watches, including wristwatches, all use, for reasons of space available on mobile display parts, double wickets or in pairs such as dates 1 at 9 of each month read either 0 - unit, or empty space - unit. This way of doing things is not very aesthetic and it would be desirable to have a centralized display in the window for both dates consisting of a single digit (1 to 9) and for two-digit dates ( 10 to 31).

Néanmoins, cette exigence esthétique est apparemment incompatible avec l'utilisation de grands chiffres au vu de la place disponible à la périphérie d'un disque d'affichage unique, notamment lorsque l'affichage se fait sur l'axe 12h - 6 h ou à sa proximité immédiate, car il faudrait diviser la périphérie du cercle en 31 espaces égaux dans chacun desquels on pourrait imprimer les dates 1 à 31 centrées dans les espaces correspondants.Nevertheless, this aesthetic requirement is apparently incompatible with the use of large numbers in view of the space available at the periphery of a single display disc, especially when the display is on the axis 12h - 6h or at its immediate proximity, because it would divide the periphery of the circle into 31 equal spaces in each of which one could print dates 1 to 31 centered in the corresponding spaces.

La présente invention a pour but de proposer un dispositif d'affichage permettant d'afficher dans un guichet situé sur l'axe 12 h - 6 h ou à sa proximité immédiate les dates 1 à 31 centrées dans le guichet et en utilisant des chiffres relativement grands.The present invention aims to provide a display device for displaying in a window located on the axis 12 h - 6 h or in its immediate vicinity dates 1 to 31 centered in the window and using relatively great.

Le dispositif selon l'invention est caractérisé par le fait qu'il comprend un premier et second disques superposés de dimensions identiques et concentriques, que le premier disque est divisé par treize rayons virtuels en autant de secteurs identiques et comprenant à proximité de sa périphérie les nombres 1 à 9 situés sur neuf rayons virtuels consécutifs, les chiffres 1 et 2 à gauche de deux rayons virtuels consécutifs suivants et les nombres 30 et 31 dont les chiffres sont situés de part et d'autre des deux derniers rayons virtuels, que le second disque est divisé par onze rayons virtuels en autant de secteurs identiques et comprenant à proximité de sa périphérie les chiffres 0 à 9 situés à droite des dix rayons virtuels consécutifs, la région du onzième rayon virtuel ne portant aucune inscription, et que le dispositif d'affichage comprend des moyens agencés pour entraîner les deux disques de sorte à afficher successivement les dates de 1 à 31 centrées dans le guichet.The device according to the invention is characterized in that it comprises a first and second superimposed discs of identical and concentric dimensions, that the first disc is divided by thirteen virtual rays into as many identical sectors and including near its periphery the numbers 1 to 9 located on nine consecutive virtual rays, the numbers 1 and 2 on the left of two consecutive virtual rays following and the numbers 30 and 31 whose numbers are located on both sides of the last two virtual rays, that the second disk is divided by eleven virtual rays in as many identical sectors and including near its periphery the numbers 0 to 9 located to the right of the ten consecutive virtual rays, the region of the eleventh virtual ray bearing no inscription, and that the device of display comprises means arranged to drive the two disks so as to successively display the dates from 1 to 31 centered in s the ticket office.

L'avantage de ce dispositif est qu'au lieu de diviser la partie périphérique d'un disque à 31 parties égales dans lesquelles on devrait pouvoir disposer les nombres 1 à 31 de sorte qu'ils soient centrés sur l'espace qui s'affichera derrière le guichet, on utilise deux disques superposés, dont un est transparent comportant treize secteurs, tandis que l'autre dispose de onze secteurs, ce qui permet d'utiliser des chiffres relativement grands. En plus, la disposition des chiffres par rapport aux rayons virtuels permet d'obtenir un centrage de l'affichage.The advantage of this device is that instead of dividing the peripheral part of a disk to 31 equal parts in which we should be able to have the numbers 1 to 31 so that they are centered on the space that will be displayed behind the wicket, we use two superimposed disks, one of which is transparent with thirteen sectors, while the other has eleven sectors, which makes it possible to use relatively large numbers. In addition, the arrangement of the figures with respect to the virtual rays makes it possible to obtain a centering of the display.

Selon une variante d'exécution, au moins le disque supérieur est fait d'un matériau transparent. De préférence, le disque transparent est en verre ou saphir ou toute autre matière transparente.According to an alternative embodiment, at least the upper disk is made of a transparent material. Preferably, the transparent disk is made of glass or sapphire or any other transparent material.

Selon une autre variante d'exécution, les moyens qui entraînent les disques sont des moyens mécaniques.According to another embodiment, the means that drive the discs are mechanical means.

Selon une autre variante d'exécution, les moyens commandant l'entraînement des disques sont des moyens électroniques. En effet, il est facile dans les montres électroniques de prévoir un microprocesseur commandant la rotation de chacun des disques en fonction de la date à afficher.According to another variant embodiment, the means controlling the driving of the disks are electronic means. Indeed, it is easy in the electronic watches to provide a microprocessor controlling the rotation of each of the disks according to the date to display.

Enfin, l'invention concerne un procédé de mise en action dudit dispositif, caractérisé par les étapes suivantes :

  1. a. le premier disque est disposé de sorte à afficher le nombre 1 situé sur le rayon virtuel, tandis que le second disque se trouve face au guichet avec la région sans inscription,
  2. b. ensuite, le premier disque tourne par période de 24 heures de 1/13ème de tour pour afficher successivement les nombres 2 à 9,
  3. c. ensuite, le premier disque tourne de 1/13ème de tour pour afficher le chiffre 1 situé à gauche du rayon virtuel et simultanément le second disque tourne de 1/11ème pour afficher le chiffre 0 de la première dizaine,
  4. d. ensuite le second disque tourne par période de 24 heures 1/11ème de tour pour afficher les unités 1 à 9,
  5. e. ensuite, le premier disque tourne de 1/13ème de tour pour afficher le chiffre 2 situé à gauche du rayon virtuel et le second disque tourne de 2/11ème pour revenir à 0 et par la suite il tourne par période de 24 heures de 1/11ème de tour pour afficher les unités 1 à 9,
  6. f. ensuite, le premier disque tourne de 1/13ème de tour pour afficher le nombre 30, tandis que le second disque tourne de 1/11ème de tour pour revenir à la position sans inscription et ensuite le premier disque tourne de 1/13ème pour afficher le nombre 31,
  7. g. enfin, le premier disque tourne de 1/13ème de tour pour afficher le nombre 1 situé sur le rayon virtuel, et le cycle recommence.
Finally, the invention relates to a method of actuating said device, characterized by the following steps:
  1. at. the first disk is arranged to display the number 1 located on the virtual ray, while the second disk is facing the window with the region without registration,
  2. b. then, the first disc rotates in a 24-hour period of 1 / 13th of a turn to successively display the numbers 2 to 9,
  3. vs. then, the first disk rotates by 1 / 13th of a turn to display the digit 1 located at the left of the virtual ray and simultaneously the second disk rotates by 1/11 th to display the digit 0 of the first tens,
  4. d. then the second disk rotates by 24 hours 1/11 th turn to display the units 1 to 9,
  5. e. then, the first disk rotates by 1/13 th round to display the number 2 located left of the virtual ray and the second disk rotates by 2/11 th to return to 0 and then it rotates every 24 hours 1/11 th turn to display the units 1 to 9,
  6. f. then, the first disk rotates by 1/13 th round to display the number 30 while the second disk rotates by 1/11 th turn to return to the position without registration, and then the first disk rotates by 1/13 th to display the number 31,
  7. boy Wut. finally, the first disk rotates by 1/13 th round to display the number 1 on the virtual radius, and the cycle repeats.

Il est également prévu, pour les mois ne comprenant pas 31 jours, de faire avancer le dispositif d'affichage par des moyens mécaniques ou électroniques entre le dernier jour d'un mois et le nombre 1 du mois suivant.It is also planned, for months not including 31 days, to advance the display device by mechanical or electronic means between the last day of a month and the number 1 of the following month.

L'invention sera décrite plus en détail à l'aide du dessin annexé.The invention will be described in more detail with the aid of the accompanying drawing.

La figure 1 montre d'une manière schématique une montre-bracelet avec un affichage à grands chiffres qui est situé sur l'axe 12h - 6h.The figure 1 schematically shows a wristwatch with a large-scale display that is located on the 12h - 6h axis.

La figure 2 est une représentation schématique du premier disque.The figure 2 is a schematic representation of the first disc.

La figure 3 est une représentation schématique du second disque.The figure 3 is a schematic representation of the second disk.

A la figure 1, nous avons représenté d'une manière tout à fait schématique une montre 1 présentant les éléments habituels et un guichet 2 pour l'affichage de la date situé sur la périphérie de la lunette et sur l'axe 12h - 6h. Le guichet peut être légèrement décalé à gauche ou à droite ou être situé en bas, donc à proximité du nombre 6, également centré ou décalé légèrement à gauche ou à droite.To the figure 1 , we have represented in a very schematic way a watch 1 presenting the usual elements and a window 2 for the display of the date located on the periphery of the telescope and on the axis 12h - 6h. The window can be slightly shifted to the left or right or be located at the bottom, so close to the number 6, also centered or shifted slightly to the left or right.

Pour pouvoir obtenir un affichage avec des chiffres aussi grands proportionnellement à la montre que ceux indiqués sur cet affichage, le dispositif est composé (voir figures 2 et 3) d'un premier disque 3 et d'un second disque 5 dont les diamètres sont identiques et sont montés coaxialement dans le boîtier de la montre. Le disque situé près du cadran qui peut indifféremment être le disque 3 ou 5, doit être fait d'un matériau transparent, par exemple du verre ou du saphir ou toute autre matière transparente. L'autre disque pourrait être également fait d'un matériau transparent, mais ceci n'est pas indispensable.To obtain a display with numbers as large as the watch shown on this display, the device is composed (see figures 2 and 3 ) a first disc 3 and a second disc 5 whose diameters are identical and are mounted coaxially in the watch case. The disc located near the dial which can indifferently be the disk 3 or 5, must be made of a transparent material, for example glass or sapphire or any other transparent material. The other disc could also be made of a transparent material, but this is not essential.

Le premier disque 3 est divisé par des rayons virtuels 4 en treize parties égales. Les nombres 1 à 9 sont imprimés sur une zone périphérique du disque 3 centrés par rapport aux rayons virtuels 4. Ensuite, les chiffres 1 et 2 sont imprimés dans les espaces consécutifs, mais légèrement décalés par rapport aux rayons virtuels, ces deux chiffres vont constituer les dizaines pour les dates commençant par 1, respectivement 2. La partie restante comprend les nombres 30 et 31 dont les chiffres 3 0 et 3 1 sont disposés de part et d'autre des rayons virtuels. De cette manière, les nombres 1 à 9 seront exactement centrés dans le guichet 2, ainsi que les nombres 30 et 31. Concernant les dates comprises entre 10 et 29, l'affichage sera expliqué par la suite lorsqu'on aura décrit également la présentation du second disque.The first disk 3 is divided by virtual rays 4 into thirteen equal parts. The numbers 1 to 9 are printed on a peripheral zone of the disc 3 centered with respect to the virtual rays 4. Then, the numbers 1 and 2 are printed in the consecutive spaces, but slightly offset relative to the virtual rays, these two figures will form the tens for the dates starting with 1, respectively 2. The remaining part comprises the numbers 30 and 31 whose numbers 30 and 31 are arranged on both sides of the rays. virtual. In this way, the numbers 1 to 9 will be exactly centered in the window 2, as well as the numbers 30 and 31. Concerning the dates between 10 and 29, the display will be explained later when the presentation will also have been described. of the second disc.

Le second disque 5 identique au niveau dimensions au premier disque 3 est divisé en onze parties égales par onze rayons virtuels 6. Les chiffres 0 à 9 sont inscrits à droite des rayons virtuels dans dix positions consécutives et ces chiffres vont constituer les unités pour les dates entre 10 et 29. Enfin, la onzième région correspondant au rayon virtuel référencé 7 ne porte aucune inscription. Cette partie du disque 5 se trouvera face au guichet 2 lorsque les nombres 1 à 9 illustrant les dates 1 à 9 seront situés également face au guichet, ce qui permettra d'avoir une présentation centrée dans ledit guichet.The second disk 5 identical in size to the first disk 3 is divided into eleven equal parts by eleven virtual rays 6. The numbers 0 to 9 are inscribed on the right of the virtual rays in ten consecutive positions and these figures will constitute the units for the dates between 10 and 29. Finally, the eleventh region corresponding to the virtual ray referenced 7 carries no inscription. This part of the disc 5 will face the counter 2 when the numbers 1 to 9 illustrating the dates 1 to 9 will also be located in front of the counter, which will have a presentation centered in said window.

Les moyens pour l'entraînement de ces deux disques selon le procédé de mise en action qui sera décrit par la suite sont soit des moyens purement mécaniques, soit des moyens commandés par des moyens électroniques.The means for driving these two disks according to the activation method which will be described later are either purely mechanical means, means controlled by electronic means.

Nous décrirons maintenant le procédé de mise en action du dispositif d'affichage.We will now describe the method of operating the display device.

Au départ, les deux disques sont disposés de sorte que dans le guichet s'affiche le nombre 1 et la partie du second disque sans inscription.Initially, the two disks are arranged so that in the window appears the number 1 and the part of the second disk without registration.

A partir de cette position, le premier disque 3 est déplacé de 1/13ème de tour huit fois consécutives par période de 24h pour afficher dans le guichet 2 les dates 1 à 9. Pendant ce temps là, le second disque 5 reste immobile. Lors du passage de la date du nombre 9 au nombre 10, le premier disque 3 est déplacé de 1/13ème de tour pour afficher le chiffre 1 représentant la première dizaine, tandis que le second disque 5 est déplacé de 1/11ème de tour pour afficher le chiffre d'unité, en l'occurrence 0. Par la suite, et par période toujours de 24h, le second disque 5 est déplacé de 1/11ème de tour pour obtenir l'affichage successif des dates 11 à 19 et pendant ce temps-là, le premier disque 3 reste immobile. Pour le passage de la date 19 à 20, le premier disque 3 est déplacé de 1/13ème de tour pour afficher dans le guichet le chiffre 2 représentant la dizaine des dates commençant par deux, tandis que le second disque 5 est déplacé de 1/13ème pour que l'affichage du chiffre 0 apparaisse dans le guichet.From this position, the first disc 3 is moved 1/13 th of a turn eight consecutive times per 24-hour period to display in the window 2 dates 1 to 9. During this time, the second disc 5 remains stationary. When changing from the date of the number 9 to the number 10, the first disc 3 is moved 1/13 th of a turn to display the digit 1 representing the first ten, while the second disc 5 is displaced by 1/11 th of turn to display the unit digit, in this case 0. Thereafter, and by period always 24h, the second disk 5 is moved 1/11 th of a turn to obtain the successive display of the dates 11 to 19 and during this time, the first disc 3 remains motionless. For the passage of the date 19 to 20, the first disc 3 is moved 1/13 th of a turn to display in the window the number 2 representing the ten dates starting with two, while the second disc 5 is moved by 1 / 13 th for that the number 0 appears in the window.

Par la suite, le premier disque 3 reste immobile, tandis que le second disque se déplace de 1/11ème de tour pour afficher successivement les unités des dates commençant par 2. Pour passer à la date suivante 30, le premier disque se déplace d'1/13ème de tour et le second disque de 1/11ème pour revenir dans la position neutre. Pour afficher la date 31, le premier disque se déplace encore de 1/13ème, ainsi la totalité des dates est affichée.Subsequently, the first disc 3 remains stationary, while the second disc moves 1/11 th of a turn to successively display the units of the dates starting with 2. To move to the next date 30, the first disc moves from '1/13 th round and the second disc of 1/11 th to return to the neutral position. To display the date 31, the first disc moves further to 1/13 th, and all dates is posted.

Pour revenir à la position de départ, donc entre le 31 et le 1er, le premier disque se déplace de 1/13ème, tandis que le second se déplace de 1/11ème de sorte à revenir à la date 1 qui sera centrée également dans le guichet 2. Par la suite, le cycle recommence de la même manière. Des moyens, bien entendu, sont prévus pour déplacer le disque lorsque le mois ne contient pas 31 jours.To return to the starting position, so between the 31st and the 1st , the first disc moves 1/13 th , while the second moves 1/11 th so to return to the date 1 which will be centered also in the window 2. Thereafter, the cycle starts again in the same way. Means, of course, are provided to move the disc when the month does not contain 31 days.

L'avantage donc de ce dispositif d'affichage est le fait que l'on puisse afficher dans un guichet situé sur l'axe midi - 6h ou à proximité de cet axe les dates avec des chiffres relativement grands et centrés dans le guichet.The advantage of this display device is the fact that we can display in a window located on the axis midi - 6 o'clock or near this axis dates with relatively large numbers and centered in the window.
