Description

La présente invention concerne généralement un dispositif d'affichage d'informations numériques et plus particulièrement un tel dispositif d'affichage pour l'indication d'informations numériques à deux chiffres telles que le quantième ou les deux derniers chiffres d'une année. Un tel dispositif est plus particulièrement destiné à être intégré dans une pièce d'horlogerie telle qu'une montre-bracelet.The present invention generally relates to a digital information display device and more particularly to such a display device for indicating two-digit digital information such as the date or the last two digits of a year. Such a device is more particularly intended to be integrated in a timepiece such as a wristwatch.

Les dispositifs d'affichage d'informations numériques à deux chiffres utilisés dans les montres-bracelets, par exemple pour indiquer le quantième, sont principalement de deux types. Un premier type comprend un disque annulaire portant une série de chiffres typiquement de 1 à 31, qui correspondent aux 31 quantièmes du mois. Le disque est entraîné d'un pas par jour par un mécanisme approprié et est visible à travers un guichet ménagé dans un cadran. L'inconvénient de ce type de ce dispositif réside dans le fait que les chiffres, qui sont de relativement petites dimensions, sont peu lisibles. Pour remédier, à cet inconvénient il a été proposé un deuxième type de dispositif d'affichage comprenant deux disques portant respectivement les chiffres des unités et les chiffres des dizaines, ces deux disques étant disposés, soit côte à côte, soit de manière concentrique. Ces dispositifs présentent une meilleure lisibilité, mais sont toutefois encombrants et leur utilisation dans des montres-bracelets limite les possibilités d'équiper ces montres-bracelet d'autres types d'affichages.The two-digit digital information display devices used in wristwatches, for example to indicate the date, are mainly of two types. A first type comprises an annular disc bearing a series of numbers typically from 1 to 31, which correspond to 31 calendar days of the month. The disk is driven one step per day by a suitable mechanism and is visible through a window provided in a dial. The disadvantage of this type of this device lies in the fact that the numbers, which are relatively small, are poorly readable. To remedy this drawback it has been proposed a second type of display device comprising two disks respectively bearing the numbers of the units and the numbers of tens, these two disks being arranged either side by side, or concentrically. These devices have a better readability, but are however bulky and their use in wristwatches limits the possibilities of equipping these wristwatches other types of displays.

On connaît également du brevet BE 449 669 une horloge pour une planche de bord de véhicule comportant un cadran formé en trois parties. Une première partie centrale mobile se présente sous la forme d'un disque portant un index des heures et faisant un tour en 12 heures, une deuxième partie se présente sous la forme d'un premier anneau portant un tour d'heures entourant le disque central et une troisième partie formée d'un anneau portant un index des minutes entourant le premier anneau et faisant un tour en une heure.Patent is also known BE 449 669 a clock for a vehicle dashboard having a dial formed in three parts. A first movable central part is in the form of a disk bearing an index of hours and making a turn in 12 hours, a second part is in the form of a first ring carrying a circle of hours surrounding the central disk and a third portion formed of a ring bearing an index of minutes surrounding the first ring and making a turn in one hour.

La présente invention a pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant un dispositif d'affichage pour l'indication d'informations numériques à deux chiffres qui soit simple et compact tout en conservant une bonne esthétique et une bonne lisibilité.The main object of the present invention is to overcome the drawbacks of the above-mentioned prior art by providing a display device for the indication of two-digit digital information that is simple and compact while maintaining good aesthetics and good readability. .

L'invention a également pour but de fournir un dispositif d'affichage pour l'indication d'informations numériques à deux chiffres qui puisse être facilement intégré dans des objets de petites dimensions telles que des pièces d'horlogerie.The invention also aims to provide a display device for the indication of two-digit digital information that can be easily integrated into small objects such as timepieces.

A cet effet, l'invention a pour objet un dispositif d'affichage pour l'indication d'informations numériques à deux chiffres, caractérisé en ce qu'il comprend un disque portant une série de chiffres répartis régulièrement le long de son pourtour, et en ce qu'il comprend en outre un premier et un deuxième pointeurs indépendants, au moins deux de ces trois éléments étant mobiles en rotation, lesdits pointeurs étant disposés respectivement à l'extérieur et à l'intérieur de la périphérie du disque pour indiquer respectivement le chiffre des dizaines et le chiffre des unités de ladite information à afficher.For this purpose, the subject of the invention is a display device for the indication of two-digit digital information, characterized in that it comprises a disk bearing a series of digits regularly distributed along its periphery, and in that it further comprises first and second independent pointers, at least two of these three elements being movable in rotation, said pointers being disposed respectively outside and inside the periphery of the disc to respectively indicate the tens digit and the units digit of the said information to be displayed.

Le dispositif d'affichage selon l'invention permet grâce à la combinaison des deux pointeurs et du disque, d'afficher une information numérique à deux chiffres à l'aide d'un seul disque portant une seule série de chiffres et ce d'une manière originale. Le dispositif d'affichage obtenu est ainsi d'une grande compacité.The display device according to the invention makes it possible, thanks to the combination of the two pointers and the disk, to display a two-digit digital information using a single disk carrying a single series of digits and this of a original way. The display device obtained is thus very compact.

Selon une caractéristique avantageuse, la série de chiffres comprend les chiffres de 0 à 9, le premier pointeur est fixe tandis que le disque et le deuxième pointeur sont mobiles en rotation autour d'un axe géométrique commun.According to an advantageous characteristic, the series of digits comprises the digits from 0 to 9, the first pointer is fixed while the disk and the second pointer are rotatable about a common geometric axis.

D'autres caractéristiques et avantages de la présente invention apparaîtront dans la description suivante d'un mode de réalisation préféré, présenté à titre d'exemple non limitatif en référence aux dessins annexés, dans lesquels :

  • la figure 1 montre une vue de face d'une pièce d'horlogerie comprenant un dispositif d'affichage selon l'invention;
  • la figure 2 montre une vue partielle en perspective et en coupe selon la ligne II-II du dispositif d'affichage selon l'invention, et
  • les figures 3 et 4 représentent des vues de face du dispositif d'affichage de l'invention dans différentes configurations d'affichage de l'année et d'un quantième respectivement.
Other features and advantages of the present invention will appear in the following description of a preferred embodiment, presented by way of non-limiting example with reference to the accompanying drawings, in which:
  • the figure 1 shows a front view of a timepiece comprising a display device according to the invention;
  • the figure 2 shows a partial view in perspective and in section along the line II-II of the display device according to the invention, and
  • the Figures 3 and 4 represent front views of the display device of the invention in different display configurations of the year and a date respectively.

En se référant à la figure 1, on voit une vue de face d'une pièce d'horlogerie 1 à calendrier, comprenant, outre des dispositifs d'affichage du jour de la semaine, du quantième et du mois, un dispositif d'affichage selon l'invention indiquant les deux derniers chiffres de l'année, désigné par la référence générale 2.Referring to the figure 1 a front view of a calendar timepiece 1 comprising, in addition to display devices of the day of the week, the date and the month, a display device according to the invention indicating the two latest figures of the year, designated by general reference 2.

Dans l'exemple illustré, le dispositif d'affichage 2 comprend un disque 4 portant une série de chiffres de 0 à 9 répartis régulièrement le long de son pourtour. Selon l'invention ces chiffres serviront comme cela apparaîtra plus clairement ci-après à indiquer à la fois les unités et les dizaines du nombre à deux chiffres que l'on entend afficher.In the example shown, the display device 2 comprises a disk 4 carrying a series of numbers from 0 to 9 regularly distributed along its periphery. According to the invention these figures will serve as it will appear more clearly below to indicate both the units and tens of the two-digit number that is intended to display.

Le disque 4 se déplace en rotation au dessus d'un cadran 6 et est entraîné par tout moyen classique approprié. Le disque 4 se déplace en regard d'un premier pointeur 8, fixe dans l'exemple illustré. Le pointeur 8 est typiquement réalisé par une décalque faite sur le cadran ou encore par une pièce rapportée sur celui-ci. Dans cet exemple, le pointeur 8 est disposé à l'extérieur de la périphérie du disque 4, selon un axe midi-six heures du disque 4 et à midi. Le pointeur 8 indique dans ce mode réalisation, et par convention, le chiffre des dizaines de l'information numérique à deux chiffres que l'on souhaite afficher. Selon une variante, il est bien entendu que le pointeur fixe 8 pourrait être disposé à n'importe quel endroit le long de la périphérie du disque 4.The disc 4 moves in rotation over a dial 6 and is driven by any suitable conventional means. The disc 4 moves next to a first pointer 8, fixed in the illustrated example. The pointer 8 is typically made by a decal made on the dial or by a patch on it. In this example, the pointer 8 is disposed outside the periphery of the disc 4, along a midi-six hour axis of the disc 4 and at noon. The pointer 8 indicates in this embodiment, and by convention, the digit of the tens of the two-digit digital information that one wishes to display. According to a variant, it is understood that the fixed pointer 8 could be disposed at any point along the periphery of the disk 4.

Comme cela ressort plus particulièrement de la figure 2, on notera que le disque 4 comprend une creusure centrale 10 qui définit à sa périphérie une couronne 12. Des chiffres 0 à 9 sont appliqués à espace régulier sur la surface de la couronne 12. Le disque 4 comprend en outre une ouverture centrale 14 pour le passage d'un d'entraînement 16 d'un deuxième pointeur 18.As is more particularly apparent from the figure 2 It should be noted that the disk 4 comprises a central hollow 10 which defines at its periphery a ring 12. Numbers 0 to 9 are applied at regular intervals on the surface of the ring 12. The disk 4 further comprises a central opening 14 for the passage of a drive 16 of a second pointer 18.

Dans l'exemple illustré, le deuxième pointeur 18 est également mobile en rotation et se déplace relativement au disque 4 en regard des chiffres portés par ce dernier. Le pointeur mobile 18 est disposé à l'intérieur de la périphérie du disque 4. Dans l'exemple illustré, le pointeur mobile 18 comprend un disque 20 sur lequel est apposé un index 22. Plus précisément, le disque 20 présente un diamètre sensiblement inférieur à celui de la creusure 10 et est disposé dans cette dernière. Le disque 20 est relié à l'axe d'entraînement 16 qui traverse l'ouverture centrale 14 du disque 4. De préférence, les surfaces supérieure de la couronne 12 et du disque 20 sont coplanaires (figure 2). Dans ce mode réalisation et par convention, le pointeur 18 indique par l'intermédiaire de l'index 22 le chiffre des unités de l'information numérique à deux chiffres que l'on souhaite afficher.In the example illustrated, the second pointer 18 is also mobile in rotation and moves relative to the disk 4 opposite the numbers carried by the latter. The movable pointer 18 is disposed inside the periphery of the disc 4. In the illustrated example, the moving pointer 18 comprises a disc 20 on which is affixed an index 22. More precisely, the disc 20 has a substantially smaller diameter. to that of the recess 10 and is disposed in the latter. The disc 20 is connected to the drive shaft 16 which passes through the central opening 14 of the disc 4. Preferably, the upper surfaces of the crown 12 and the disc 20 are coplanar ( figure 2 ). In this embodiment and by convention, the pointer 18 indicates via the index 22 the digit of the units of the two-digit digital information that is to be displayed.

Dans le cas où l'on souhaite afficher les deux derniers chiffres de l'année, le disque 4 est associé à des premiers moyens d'entraînement (non représentés) qui l'incrémentent d'une unité tous les dix ans tandis que le pointeur mobile 18 est associé à des deuxièmes moyens d'entraînement (non représentés) qui l'incrémentent d'une unité tous les ans. A titre d'exemple, ces moyens d'entraînement peuvent être formés d'un train d'engrenages entraîné par des moyens mécaniques ou encore par un moteur pas à pas commandé par un microprocesseur programmé de façon appropriée.In the case where it is desired to display the last two digits of the year, the disc 4 is associated with first drive means (not shown) which increment it by one unit every ten years while the pointer mobile 18 is associated with second drive means (not shown) which increment a unit every year. For example, these drive means may be formed of a gear train driven by mechanical means or by a stepper motor controlled by a microprocessor programmed appropriately.

A la figure 3, on a représenté à titre illustratif trois configurations du dispositif d'affichage selon l'invention indiquant les deux derniers chiffres des années 2008, 2009 et 2010. Pour l'année 2008, le pointeur fixe 8 pointe en direction du chiffre des dizaines, soit 0 tandis que le pointeur mobile 18 pointe par l'intermédiaire de l'index 22 dans la direction du chiffre des unités, soit le chiffre 8. Pour l'année 2009, le disque 4 est resté immobile de sorte que le pointeur fixe 8 pointe toujours en direction de 0, le chiffre des dizaines n'a pas changé. Le pointeur mobile 18 a lui avancé d'un pas dans le sens horaire pour venir pointer en direction du chiffre 9 représentant le chiffre des unités. Pour l'année 2010, le pointeur fixe 8 pointe désormais en direction du chiffre 1, c'est à dire que le disque 4 a avancé d'un pas dans le sens anti-horaire pour amener le pointeur fixe 8 en face du chiffre 1 représentant le chiffre des dizaines, tandis que l'index 22 du pointeur mobile 18 pointe en direction du chiffre 0.To the figure 3 three configurations of the display device according to the invention, representing the last two digits of the years 2008, 2009 and 2010, are represented by way of illustration. For the year 2008, the fixed pointer 8 points in the direction of the number of tens, namely 0 while the mobile pointer 18 points through the index 22 in the direction of the units digit, the number 8. For the year 2009, the disc 4 has remained stationary so that the fixed pointer 8 points always in the direction of 0, the number of tens has not changed. The moving pointer 18 has advanced one step clockwise to come to point to the digit 9 representing the number of units. For the year 2010, the fixed pointer 8 now points to the number 1, that is to say that the disc 4 has advanced one step counterclockwise to bring the fixed pointer 8 in front of the number 1 representing the tens digit, while the index 22 of the moving pointer 18 points to the digit 0.

Selon une deuxième application, le dispositif d'affichage selon l'invention illustré à la figure 4 ce dernier peut indiquer un quantième. Dans ce cas le disque 4 est associé à des premiers moyens d'entraînement (non représentés) qui l'incrémentent pour amener les chiffres 1, 2, 3 et 0 en regard du pointeur 8 fixe, respectivement à la fin des 9, 19, 29, 30 et le cas échéant 31èmes jours, tandis que le deuxième pointeur est associé à des deuxièmes moyens d'entraînement (non représentés) qui l'incrémente d'une unité par jour.According to a second application, the display device according to the invention illustrated in FIG. figure 4 the latter can indicate a date. In this case the disk 4 is associated with first drive means (not shown) which increment it to bring the numbers 1, 2, 3 and 0 opposite the fixed pointer 8, respectively at the end of the 9, 19, 29, 30 and if necessary 31st days, while the second pointer is associated with second drive means (not shown) which increments it by one unit per day.

A des fins d'illustration, on a également représenté à la figure 4 le dispositif d'affichage selon l'invention dans plusieurs configurations d'affichage de deux derniers chiffre d'un quantième. Le principe de lecture est le même que celui décrit précédemment en liaison avec la figure 3.For purposes of illustration, it has also been shown figure 4 the display device according to the invention in several display configurations of the last two digits of a date. The reading principle is the same as that described above in connection with the figure 3 .

L'invention n'est bien entendu pas limitée au mode de réalisation décrit ci-dessus et différentes variantes de réalisation peuvent être envisagées. En particulier, on notera que l'on peut prévoir, selon une première variante que le disque 4 soit fixe et que le pointeur 8 soit porté par un organe mobile en rotation le long de la périphérie du disque 4. On peut également prévoir, selon une deuxième variante, que le pointeur 18 soit fixe, et que le pointeur 8 et le disque 4 soient tous les deux mobiles en rotation. Bien entendu, les pointeurs mobiles évoqués plus haut et formés par des disques peuvent être remplacés par des aiguilles ou tout autre moyen d'indication approprié.The invention is of course not limited to the embodiment described above and different embodiments can be envisaged. In particular, it should be noted that it is possible, according to a first variant, for the disc 4 to be stationary and for the pointer 8 to be carried by a member movable in rotation along the periphery of the disc 4. It is also possible, according to a second variant, that the pointer 18 is fixed, and that the pointer 8 and the disc 4 are both rotatable. Of course, the movable pointers mentioned above and formed by disks can be replaced by needles or any other appropriate means of indication.

Par ailleurs, dans la description qui précède on a choisi par convention d'indiquer le chiffre des dizaines par le pointeur se trouvant à l'extérieur de la périphérie du disque 4 et d'indiquer le chiffre des unités par le pointeur se trouvant à l'intérieur de sa périphérie et plus particulièrement du coté du bord intérieur de la couronne 12 mais il est bien entendu que l'inverse peut être envisagé.Furthermore, in the foregoing description, it has conventionally been chosen to indicate the number of the tens by the pointer lying outside the periphery of the disc 4 and to indicate the number of the units by the pointer at the end of the disc. interior of its periphery and more particularly on the side of the inner edge of the crown 12 but it is understood that the opposite can be envisaged.

On comprendra que d'autres modifications et/ou adaptations peuvent être apportées au dispositif d'affichage qui vient d'être décrit sans sortir du cadre de l'invention défini par les revendication annexées.It will be understood that other modifications and / or adaptations may be made to the display device which has just been described without departing from the scope of the invention defined by the appended claims.
