Description

La présente invention concerne un dispositif indicateur analogique notamment pour pièce d'horlogerie, plus particulièrement un dispositif indicateur comprenant un organe rotatif, tel qu'un cadran, une partie de cadran ou une lunette, portant des indications telles que des chiffres et/ou une graduation.The present invention relates to an analog indicator device, in particular for a timepiece, more particularly to an indicator device comprising a rotary member, such as a dial, a part of a dial or a telescope, bearing indications such as numbers and / or graduation.

On connaît par le brevet japonais JP 2599344 un dispositif indicateur analogique comprenant une lunette rotative comprenant elle-même des logements dans lesquels sont disposés mobiles en rotation sur eux-mêmes des plots portant des indications sur leur face supérieure. Une tige fait saillie sur la face inférieure de chaque plot de manière excentrée par rapport à l'axe du plot, et est guidée dans une rainure circulaire excentrée par rapport au cadran. Le guidage de la tige dans la rainure fait tourner le plot dans son logement lors d'une rotation de la lunette de sorte que l'indication portée par le plot conserve en permanence la même orientation, pour faciliter la lecture de l'indication. Il semble qu'avec ce dispositif un risque de blocage existe dans la position à 180° de la lunette, comme expliqué dans la demande de brevet européen EP 1 345 094 .We know by the Japanese patent JP 2599344 an analog indicating device comprising a rotating bezel itself comprising housings in which are arranged rotatable on themselves pads bearing indications on their upper face. A rod protrudes on the underside of each stud eccentrically relative to the axis of the stud, and is guided in a circular groove eccentric to the dial. Guiding the rod in the groove rotates the stud in its housing during a rotation of the bezel so that the indication carried by the stud keeps permanently the same orientation, to facilitate the reading of the indication. It seems that with this device a risk of blockage exists in the 180 ° position of the telescope, as explained in the European patent application. EP 1 345 094 .

La demande de brevet européen EP 1 345 094 décrit un dispositif similaire à celui selon le brevet JP 2599344 , mais dans lequel les plots comportent plusieurs tiges excentrées sur leur face inférieure qui sont guidées dans des rainures circulaires excentrées respectives. Ce dispositif a pour inconvénient d'être très sensible aux tolérances de fabrication. En effet, pour un guidage correct des tiges dans les rainures, et pour éviter les risques de blocage, les tiges et les rainures doivent avoir des dimensions très précises, d'autant plus que les rainures se croisent.The European patent application EP 1 345 094 describes a device similar to that according to the patent JP 2599344 but in which the pads have a plurality of eccentric rods on their underside which are guided in respective eccentric circular grooves. This device has the disadvantage of being very sensitive to manufacturing tolerances. Indeed, for proper guidance of the rods in the grooves, and to avoid the risk of blockage, the rods and grooves must have very precise dimensions, especially as the grooves intersect.

La présente invention vise à proposer un dispositif indicateur analogique notamment pour pièce d'horlogerie qui facilite la lecture des indications portées par un organe rotatif tout en étant simple et fiable.The present invention aims to provide an analog indicator device including a timepiece that facilitates the reading of the indications carried by a rotary member while being simple and reliable.

A cette fin est prévu un dispositif indicateur analogique comprenant un organe rotatif comprenant un ou des logements dans lesquels sont disposés mobiles en rotation sur eux-même un ou des organes indicateurs respectifs portant chacun au moins une indication, caractérisé en ce qu'il comprend en outre un ou des pignons respectivement solidaires du ou des organes indicateurs et en prise avec une denture fixe coaxiale avec l'organe rotatif, les rapports d'engrenage entre la denture fixe et le ou les pignons étant choisis pour que l'indication portée par le ou chaque organe indicateur ait la même orientation à des positions angulaires déterminées de l'organe rotatif.For this purpose an analogue indicator device is provided comprising a rotary member comprising one or more housings in which are arranged rotatable on themselves one or more respective indicator members each carrying at least one indication, characterized in that it comprises in in addition to one or more pinions respectively integral with the indicator member (s) and engaged with a fixed toothing coaxial with the rotary member, the gear ratio between the fixed toothing and the pinion or gears being chosen so that the indication carried by the or each indicator member has the same orientation at specific angular positions of the rotary member.

Typiquement, le dispositif indicateur analogique comprend plusieurs organes indicateurs portant des indications respectives qui ont la même orientation.Typically, the analog indicator device comprises several indicator organs bearing respective indications that have the same orientation.

L'organe rotatif est par exemple un disque.The rotary member is for example a disc.

De préférence, les positions angulaires déterminées sont des positions stables dans lesquelles l'organe rotatif est maintenu au moyen d'un ressort.Preferably, the determined angular positions are stable positions in which the rotary member is held by means of a spring.

Le dispositif indicateur analogique peut comprendre un organe de commande manuel pour commander les déplacements de l'organe rotatif.The analog indicating device may comprise a manual control member for controlling the movements of the rotary member.

La présente invention propose également une pièce d'horlogerie comprenant un dispositif indicateur analogique tel que défini ci-dessus, par exemple pour indiquer des heures. La pièce d'horlogerie peut comprendre en outre des indications fixes pour indiquer les heures d'un premier fuseau horaire et le dispositif indicateur analogique peut servir à indiquer les heures d'un deuxième fuseau horaire distinct du premier fuseau horaire. En variante, le dispositif indicateur analogique peut servir à indiquer une réserve de marche, les minutes, le quantième, le jour de la semaine ou le mois.The present invention also proposes a timepiece comprising an analog indicator device as defined above, for example to indicate hours. The timepiece may further include fixed indications for indicating the times of a first time zone and the analog indicating device may be used to indicate the times of a second time zone distinct from the first time zone. Alternatively, the analog indicator device can be used to indicate a power reserve, the minutes, the day, the day of the week or the month.

  • the figure 1 is a schematic top plan view of a timepiece according to the invention;
  • the figure 2 is a schematic top plan view of the timepiece according to the invention in a configuration other than the figure 1 ;

En référence à la figure 1, une pièce d'horlogerie 1, telle qu'une montre-bracelet, une montre de poche, une pendule, etc., selon un mode de réalisation particulier de l'invention, comprend notamment un cadran 2 au-dessus duquel sont montées des aiguilles indicatrices 3. Le cadran 2 comprend une partie annulaire externe fixe 4, une partie annulaire intermédiaire mobile 5 et une partie centrale fixe 6, ces trois parties 4, 5, 6 ayant pour axe l'axe, désigné par le repère 7, du cadran 2, autour duquel tournent les aiguilles 3. La partie annulaire externe fixe 4 porte des indications des heures 8, telles qu'une graduation associée ou non à des chiffres. La partie intermédiaire mobile 5 porte elle aussi des indications des heures 9, sous forme de quatre chiffres « 3 », « 6 », « 9 » et « 12 » répartis à 90°. Ces indications 9 sont orientées dans le même sens de lecture, à savoir horizontal de gauche à droite dans la vue de la figure 1 considérée comme verticale.With reference to the figure 1 , a timepiece 1, such as a wristwatch, a pocket watch, a pendulum, etc., according to a particular embodiment of the invention, comprises in particular a dial 2 above which are mounted indicator hands 3. The dial 2 comprises a fixed outer annular portion 4, a movable intermediate annular portion 5 and a fixed central portion 6, these three parts 4, 5, 6 having the axis, indicated by the reference numeral 7, of the Dial 2, around which the needles turn 3. The fixed outer annular portion 4 carries indications of the hours 8, such as a graduation associated or not with numbers. The moving intermediate portion 5 also bears indications of hours 9, in the form of four numbers "3", "6", "9" and "12" distributed at 90 °. These indications 9 are oriented in the same direction of reading, namely horizontal from left to right in the view of the figure 1 considered vertical.

La partie externe 4 et la partie centrale 6 du cadran 2 sont les surfaces supérieures d'une pièce externe et d'une pièce centrale, respectivement, fixées à une platine 12 fixée elle-même au mouvement de la pièce d'horlogerie (non représenté). Aux figures 3 et 4, ladite pièce centrale est désignée par le repère 11 et ladite pièce externe n'a pas été représentée. La partie intermédiaire mobile 5 du cadran 2 est elle définie par un disque rotatif 13 guidé autour d'une portée cylindrique 14 de la pièce centrale fixe 11 et par des organes indicateurs 15 montés sur le disque 13 et portant les indications 9. Le disque 13 est rotatif autour de l'axe 7 entre douze positions angulaires stables régulièrement réparties. Le passage d'une position stable à une autre est effectué sous l'action d'un levier 16 actionnable manuellement depuis l'extérieur de la boîte de la pièce d'horlogerie et soumis à l'action d'un ressort de rappel 17, ce levier 16 coopérant avec une denture 18 de 12 dents située du côté de la surface inférieure du disque 13 et solidaire de ce dernier. A chaque actionnement du levier 16, celui-ci fait ainsi tourner le disque 13 et avec lui les organes indicateurs 15 d'un douzième de tour autour de l'axe 7. Le disque 13 est maintenu dans chacune de ses positions stables par un ressort à lame 19 dont une première extrémité est fixée à la platine 12 par l'intermédiaire d'un plot 20 et dont la seconde extrémité coopère avec l'une de douze encoches 21 régulièrement réparties à la périphérie du disque 13, dans la surface inférieure de ce dernier.The outer portion 4 and the central portion 6 of the dial 2 are the upper surfaces of an outer piece and a central piece, respectively, fixed to a plate 12 itself fixed to the movement of the timepiece (not shown ). To the figures 3 and 4 said central part is designated by the reference 11 and said outer part has not been shown. The movable intermediate portion 5 of the dial 2 is defined by a rotating disc 13 guided around a scope cylindrical 14 of the fixed central part 11 and by indicator members 15 mounted on the disc 13 and bearing the indications 9. The disc 13 is rotatable about the axis 7 between twelve stable angular positions regularly distributed. The passage from one stable position to another is performed under the action of a lever 16 manually operable from outside the timepiece box and subjected to the action of a return spring 17, this lever 16 cooperating with a toothing 18 of 12 teeth located on the side of the lower surface of the disc 13 and secured thereto. With each actuation of the lever 16, the latter thus rotates the disc 13 and with it the indicator members 15 of a twelfth of a turn around the axis 7. The disc 13 is held in each of its stable positions by a spring with a blade 19 whose first end is fixed to the plate 12 by means of a stud 20 and whose second end cooperates with one of twelve notches 21 regularly distributed at the periphery of the disc 13, in the lower surface of this last.

Les indications fixes 8 et mobiles 9 et les aiguilles 3 avec lesquelles elles coopèrent servent à indiquer simultanément les heures locales de lieux géographiques situés dans deux fuseaux horaires différents. Par la graduation fixe 8 et les aiguilles des heures et des minutes sont indiquées les heures et les minutes de l'heure locale d'un premier fuseau horaire, typiquement celui où l'utilisateur se trouve. Par les indications 9 et l'aiguille des heures sont indiquées les heures du second fuseau horaire et par la graduation fixe 8 et l'aiguille des minutes sont indiquées les minutes du second fuseau horaire. Le levier 16 sert à régler le disque 13 à la position angulaire correspondant au nombre d'heures de décalage entre les premier et second fuseaux horaires.The fixed and movable indications 8 and the needles 3 with which they cooperate serve to simultaneously indicate the local times of geographical locations located in two different time zones. By the fixed graduation 8 and the hour and minute hands are indicated the hours and minutes of the local time of a first time zone, typically the one where the user is located. By the indications 9 and the hour hand are indicated the hours of the second time zone and by the fixed graduation 8 and the minute hand are indicated the minutes of the second time zone. The lever 16 serves to adjust the disk 13 to the angular position corresponding to the number of hours of offset between the first and second time zones.

En référence aux figures 3 et 4, chaque organe indicateur 15 est constitué d'un disque 22 sur la surface supérieure duquel est inscrite l'indication 9 et qui est prolongé centralement du côté de sa surface inférieure par un plot 23. Le plot 23 traverse un trou 24 pratiqué dans l'épaisseur du disque 13 et y est guidé en rotation sur lui-même par un palier 25, par exemple en rubis. Un pignon 26 est fixé rigidement, par exemple chassé, à l'extrémité du plot 23 et forme ainsi avec l'organe indicateur 15 un ensemble rigide mobile en rotation par rapport au disque 13 autour d'un axe de symétrie commun 27. Une couronne 28 coaxiale avec les pièces 11 et 13 est fixée rigidement, par exemple chassée, autour d'une portée 29 de la pièce centrale fixe 11, sous le disque 13. Cette couronne 28 comporte à sa périphérie une denture 30 qui est en prise avec les dentures des pignons 26. La couronne 28 comporte également sur sa surface supérieure une saillie d'appui 31 sur laquelle repose le disque 13, ce dernier étant aussi retenu du côté de sa surface supérieure (côté cadran) par un débord 32 de la pièce centrale fixe 11. Interposé entre les pignons 26 et les disques 22, le disque 13 maintient les organes indicateurs 15 dans les trous ou logements 24.With reference to figures 3 and 4 each indicator member 15 consists of a disc 22 on the upper surface of which is indicated the indication 9 and which is extended centrally on the side of its lower surface by a stud 23. The stud 23 passes through a hole 24 formed in the the thickness of the disk 13 and is guided in rotation on itself by a bearing 25, for example ruby. A pinion 26 is fixed rigidly, for example driven, at the end of the stud 23 and thus forms with the indicator member 15 a rigid assembly rotatable relative to the disc 13 about a common axis of symmetry 27. A coaxial ring 28 with the parts 11 and 13 is fixed rigidly, for example driven, around a bearing 29 of the fixed central piece 11, under the disc 13. This ring 28 comprises at its periphery a toothing 30 which is engaged with the teeth of the pinions 26. The ring 28 also has on its upper surface a bearing projection 31 on which the disk 13 rests, the latter being also retained on the side of its upper surface (dial side) by an overflow 32 of the fixed central part 11. Interposed between the pinions 26 and the disks 22, the disc 13 holds the indicator members 15 in the holes or housings 24.

Lorsque le disque 13 est entraîné en rotation par le levier 16, il entraîne avec lui les organes indicateurs 15 qui, du fait de l'engrènement entre les dentures des pignons 26 et de la couronne fixe 28, tournent sur eux-mêmes dans les trous 24 dans le même sens de rotation que le disque 13. Les indications 9 tournent donc par rapport au disque 13 et par rapport aux parties fixes (platine 12, boîte, etc.) de la pièce d'horlogerie. Le rapport d'engrenage (rapport entre le nombre de dents ou entre le nombre de tours) entre chaque pignon 26 et la couronne 28 est choisi pour que les organes indicateurs 15 tournent sur eux-mêmes d'un tour moins 30° (un tour moins 360°/12) lors du passage d'une position stable à une position stable consécutive du disque 13. Ainsi, à la fin de ce mouvement, les indications 9 retrouvent l'orientation commune qu'elles avaient avant ce mouvement, comme montré à la figure 2. De cette manière, les indications 9 ont la même orientation commune, c'est-à-dire sont lisibles dans le même sens, dans toutes les positions stables du disque 13, ce qui en facilite la lecture évitant à l'utilisateur de devoir tourner la tête pour les lire. Cet effet est obtenu de manière simple et sans risque de blocage du disque 13. Entre deux positions stables du disque 13, la rotation des indications 9 sur elles-mêmes confère un aspect ludique et attrayant à la pièce d'horlogerie, ceci d'autant plus que les indications 9 tournent en synchronisme, c'est-à-dire que les orientations respectives des indications 9 restent à tout moment identiques entre elles.When the disc 13 is rotated by the lever 16, it carries with it the indicator members 15 which, because of the meshing between the teeth of the pinions 26 and the fixed ring 28, rotate on themselves in the holes 24 in the same direction of rotation as the disc 13. The indications 9 rotate relative to the disc 13 and relative to the fixed parts (plate 12, box, etc.) of the timepiece. The gear ratio (ratio between the number of teeth or between the number of revolutions) between each pinion 26 and the ring gear 28 is chosen so that the indicator members 15 turn about themselves by one turn minus 30 ° (one turn minus 360 ° / 12) during the transition from a stable position to a stable consecutive position of the disc 13. Thus, at the end of this movement, the indications 9 find the common orientation that they had before this movement, as shown to the figure 2 . In this way, the indications 9 have the same common orientation, that is to say they are readable in the same direction, in all the stable positions of the disc 13, which facilitates the reading avoiding the user having to turn the head to read them. This effect is obtained in a simple manner and without risk of blocking the disc 13. Between two stable positions of the disc 13, the rotation of the indications 9 on themselves gives a playful and attractive aspect to the timepiece, this all the more more that the indications 9 rotate in synchronism, that is to say that the respective orientations of the indications 9 remain at all times identical to each other.

Dans un exemple de réalisation, la denture 30 de la couronne 28 comporte 132 dents et celle de chaque pignon 26 comporte 12 dents. Ces nombres de dents peuvent bien entendu être modifiés, pour autant que le rapport d'engrenage précité soit respecté. En variante, le rapport d'engrenage peut être tel que chaque pignon 26 tourne de N tour(s) plus un tour moins 30°, où N est un nombre entier supérieur ou égal à 1.In an exemplary embodiment, the toothing 30 of the ring 28 has 132 teeth and that of each pinion 26 has 12 teeth. These numbers of teeth can of course be modified, as long as the gear ratio mentioned above is respected. Alternatively, the gear ratio may be such that each pinion 26 rotates N turn (s) plus one turn minus 30 °, where N is an integer greater than or equal to 1.

Dans d'autres variantes, la couronne 28 pourrait avoir un plus grand diamètre et une denture intérieure en prise avec les pignons 26. Dans ce cas, les pignons 26 et organes indicateurs 15 tourneraient sur eux-mêmes dans le sens opposé au sens de rotation du disque 13 et le rapport d'engrenage entre chaque pignon 26 et la denture de la couronne 28 serait donc choisi pour que chaque pignon 26 tourne de N tour(s) plus 30°, où N est un nombre entier supérieur ou égal à 1. Selon un exemple de réalisation, la denture intérieure de la couronne 28 comporterait 156 dents et la denture de chaque pignon 26 comporterait 12 dents.In other variants, the ring 28 could have a larger diameter and an internal toothing engaged with the pinions 26. In this case, the pinions 26 and indicator members 15 would rotate on themselves in the direction opposite to the direction of rotation of the disc 13 and the gear ratio between each pinion 26 and the toothing of the ring gear 28 would therefore be chosen so that each pinion 26 rotates by N turn (s) plus 30 °, where N is an integer greater than or equal to 1 According to an exemplary embodiment, the internal toothing of the ring 28 comprises 156 teeth and the toothing of each pinion 26 comprises 12 teeth.

Dans le mode de réalisation décrit, les organes indicateurs 15 sont au nombre de quatre. IIs pourraient bien entendu être en nombre différent, inférieur ou supérieur. Il pourrait par exemple y avoir douze organes indicateurs portant les chiffres « 1 » à « 12 », ou un seul organe indicateur portant le chiffre « 12 ».In the embodiment described, the indicator members 15 are four in number. They could of course be in different numbers, inferior or superior. For example, there could be twelve indicator bodies bearing the numbers "1" to "12", or a single indicator organ with the number "12".

Par ailleurs, au lieu d'être sous la forme d'un module additionnel comportant sa propre platine 12, comme représenté, le dispositif indicateur analogique selon l'invention pourrait être monté directement sur la platine du mouvement.Furthermore, instead of being in the form of an additional module having its own plate 12, as shown, the analog indicator device according to the invention could be mounted directly on the movement stage.

Le principe du dispositif indicateur analogique décrit ci-dessus pourrait être utilisé dans d'autres applications que l'affichage d'un double fuseau horaire, par exemple pour afficher une réserve de marche, les heures, les minutes, le quantième, le jour de la semaine ou le mois en coopération avec un index fixe du cadran. Une application particulière pourrait consister à intégrer ce dispositif à un mécanisme de quantième perpétuel pour afficher simultanément le quantième en cours et le quantième suivant à travers un guichet, ces deux quantièmes ayant la même orientation. Dans tous ces exemples, le disque rotatif 13 serait commandé par le mouvement de la pièce d'horlogerie, et non plus uniquement par un levier manuel, et serait déplaçable de manière instantanée entre des positions discrètes. De façon analogue au mode de réalisation décrit en référence aux figures, le rapport d'engrenage entre les pignons 26 et la denture fixe 30 serait de N tour(s) - 360°/P pour une denture fixe 30 extérieure et de N tour(s) + 360°/P pour une denture fixe 30 intérieure, N étant un nombre entier supérieur ou égal à 1 et P étant le nombre de positions discrètes du disque 13. Il est clair également que des applications non horlogères peuvent être envisagées pour la présente invention.The principle of the analog indicator device described above could be used in other applications than the display of a dual time zone, for example to display a power reserve, the hours, the minutes, the date, the day of the week or the month in cooperation with a fixed index of the dial. A particular application might be to integrate this device into a perpetual calendar mechanism for simultaneously displaying the current calendar and the next calendar through a window, these two calendars having the same orientation. In all these examples, the rotating disk 13 would be controlled by the movement of the timepiece, and no longer only by a manual lever, and could be moved instantaneously between discrete positions. In a similar manner to the embodiment described with reference to the figures, the gear ratio between the pinions 26 and the fixed toothing 30 would be N turn (s) - 360 ° / P for an external fixed toothing and N turn ( s) + 360 ° / P for an internal fixed toothing, N being an integer greater than or equal to 1 and P being the number of discrete positions of the disc 13. It is also clear that non-horological applications can be envisaged for the present invention.
