Ce dispositif comprend une étoile de correction fixée au canon des heures, qui est liée à la roue des heures ajustée à pivotement libre autour du canon par l'intermédiaire d'un sautoir dont la tête prend place entre deux sommets de l'étoile et assure la relation angulaire entre cette dernière par rapport à la roue des heures. Le canon des heures peut donc être pivoté angulairement par rapport à la roue des heures en agissant manuellement sur l'étoile avec un levier de correction, une action dudit levier engendrant un pivotement d'un pas de l'étoile.The document CH 685 965G reveals a display device that makes it possible to modify an indication of the time in steps of one hour, without deindexing this indication with respect to that of the minutes. This device comprises a correction star fixed to the hour gun, which is linked to the hour wheel adjusted to free rotation around the barrel via a jumper whose head takes place between two peaks of the star and ensures the angular relation between the latter with respect to the hour wheel. The hour gun can therefore be rotated angularly with respect to the hour wheel by manually acting on the star with a correction lever, an action of said lever generating a pivoting pitch of the star.

Ce genre d'agencement est devenu standard pour des pièces d'horlogerie à deux fuseaux horaires, car il permet de modifier seule la position angulaire d'un indicateur des heures, sans le désindexer par rapport à l'affichage des minutes. Les deux indications restent en phase lors d'une correction par l'intermédiaire de la tige de mise à l'heure. Cependant, l'actionnement du mécanisme par l'utilisateur afin de modifier seule l'indication de l'heure peut appliquer un couple indésirable sur le rouage de finissage lors d'une correction, car la force exercée par le sautoir doit être surmontée afin de faire avancer ou reculer l'étoile d'un pas. Ce couple indésirable peut nuire à la marche du mouvement.This kind of arrangement has become standard for timepieces with two time zones, because it allows to modify only the angular position of an hour indicator, without deindexing it with respect to the display of the minutes. Both indications remain in phase during a correction via the time setting rod. However, actuation of the mechanism by the user to change only the time indication may apply undesirable torque on the finishing train during a correction, because the force exerted by the jumper must be overcome in order to move the star forward or backward. This unwanted couple can hinder movement.

Le document CH 665 930 dévoile une pièce d'horlogerie à plusieurs fuseaux horaires dans laquelle cet inconvénient a été surmonté. Au centre du mouvement se trouve un jeu d'aiguilles conventionnel pour l'indication de l'heure locale sur une échelle de 12 heures. Le canon des heures est solidaire d'un pignon qui sert de prise de force pour une pluralité de dispositifs d'indication de l'heure dans d'autres fuseaux horaires sur des échelles de 24h. L'aiguille des heures pour chaque fuseau horaire est entraînée par une sortie d'un engrenage différentiel, l'une de ses entrées étant menée par ledit pignon par l'intermédiaire d'un engrenage réducteur. L'autre entrée de l'engrenage différentiel porte un disque de lieux muni d'indications de villes, qui est entraîné en rotation par une tige de correction.The document CH 665 930 unveils a timepiece in several time zones in which this disadvantage has been overcome. At the center of the movement is a conventional needle set for local time indication on a 12-hour scale. The hours gun is secured to a pinion which serves as a power take-off for a plurality of timekeeping devices in other time zones on 24h scales. The hour hand for each time zone is driven by an output of a differential gear, one of its inputs being driven by said gear by means of a gear reduction gear. The other input of the differential gear carries a location disc with city indications, which is rotated by a correction rod.

Lorsque la pièce fonctionne normalement, le disque de lieux reste immobile, et l'engrenage différentiel agit en tant que renvoi simple, l'aiguille des heures du fuseau horaire étant entraînée à partir du canon des heures. Lors d'une action d'un utilisateur sur la tige de correction, le disque de villes est pivoté et l'engrenage différentiel entraîne en même temps l'aiguille des heures du fuseau horaire. Grâce à l'utilisation d'un engrenage différentiel, cette modification de la position angulaire de l'aiguille des heures du fuseau horaire n'applique sensiblement pas de couple indésirable sur le rouage de finissage. Néanmoins, cet agencement n'assure pas la bonne indexation entre l'aiguille des minutes et l'heure des heures du fuseau horaire, qui peut ainsi prendre une position angulaire inadaptée si l'utilisateur n'effectue pas l'ajustement avec suffisamment de soin.When the coin is operating normally, the location disk remains stationary, and the differential gear acts as a single return, the hour hand of the time zone being driven from the hour gun. During a user action on the correction rod, the city disc is rotated and the differential gear drives at the same time the hour hand of the time zone. Through the use of a differential gear, this change in the angular position of the hour hand of the time zone applies substantially no unwanted torque on the work train. Nevertheless, this arrangement does not ensure the correct indexation between the minute hand and the time of hours in the time zone, which can thus take an inappropriate angular position if the user does not perform the adjustment with sufficient care. .

Finalement, le document EP 2 663 902 décrit un dispositif d'affichage dont le système de correction permet la correction de deux informations simultanément, et la correction de l'une ou l'autre de ces dernières individuellement. Dans ce dispositif, le premier organe d'affichage est entraîné conventionnellement, et l'autre est solidaire en rotation de la sortie d'un engrenage différentiel. L'une des entrées de cet engrenage différentiel est menée par le rouage qui entraîne le premier organe d'affichage, et l'autre est solidaire en rotation d'une étoile de correction. Par ailleurs, un système de freinage est prévu, ce qui empêche l'entraînement du deuxième organe d'affichage lorsque l'utilisateur veut corriger seul le premier organe d'affichage.Finally, the document EP 2 663 902 describes a display device whose correction system allows the correction of two pieces of information simultaneously, and the correction of one or the other of them individually. In this device, the first display member is conventionally driven, and the other is rotatably connected to the output of a differential gear. One of the inputs of this differential gear is driven by the gear train that drives the first display member, and the other is rotatably connected to a correction star. Furthermore, a braking system is provided, which prevents the drive of the second display member when the user wants to correct only the first display member.

Cependant, l'un des buts de ce dispositif est de pouvoir, le cas échéant, découpler les deux organes d'affichage et d'ainsi permettre leur déphasage, ce qui est avantageux pour certaines applications. Néanmoins, pour d'autres applications, telle qu'une indication des heures et des minutes, ou d'une indication de l'heure dans plusieurs fuseaux horaires, un tel déphasage n'est pas souhaité et est même contre-indiqué.However, one of the purposes of this device is to be able, if necessary, decouple the two display members and thus allow their phase shift, which is advantageous for certain applications. Nevertheless, for other applications, such as an indication of hours and minutes, or of an indication of the time in several time zones, such a phase shift is not desired and is even contraindicated.

Divulgation de l'inventionDisclosure of the invention

Un but principal de la présente invention est de pallier les inconvénients de l'art antérieur, en proposant un dispositif d'affichage pour mouvement d'horlogerie qui permet une correction de deux indications liées au temps selon plusieurs modes de correction, et ce sans engendrer aucun déphasage des indications.A main object of the present invention is to overcome the drawbacks of the prior art, by proposing a display device for a watch movement which makes it possible to correct two indications related to time according to several correction modes, and without generating no phase shift of the indications.

À cet effet, la présente invention concerne plus particulièrement un dispositif d'affichage pour mouvement d'horlogerie, ledit dispositif d'affichage comprenant un premier engrenage destiné à être entraîné par un organe moteur que comporte ledit mouvement, tel qu'un ressort moteur logé dans un barillet, un moteur électrique ou similaire, et un dispositif de correction principal agencé pour entraîner sélectivement ledit premier engrenage. Le dispositif comprend en outre un premier engrenage correcteur comprenant une première entrée agencée pour être entraînée par ledit premier engrenage, une seconde entrée destinée à être entraînée manuellement par pas, et une sortie agencée pour entraîner un premier organe d'affichage d'une première indication liée au temps, telle que les minutes. Ce premier engrenage correcteur peut être par exemple un engrenage différentiel ou un correcteur rapide du genre communément utilisé dans des dispositifs d'affichage du temps selon deux fuseaux horaires.To this end, the present invention relates more particularly to a display device for a watch movement, said display device comprising a first gear intended to be driven by a motor member that includes said movement, such as a motor spring housed in a barrel, an electric motor or the like, and a main correction device arranged to selectively drive said first gear. The device further comprises a first correction gear comprising a first input arranged to be driven by said first gear, a second input to be manually driven in steps, and an output arranged to drive a first display member of a first indication. related to time, such as minutes. This first corrective gear may for example be a differential gear or a rapid corrector of the type commonly used in time display devices in two time zones.

Selon l'invention, le dispositif d'affichage comprend également un second engrenage correcteur, qui peut être similaire ou différent dudit premier engrenage correcteur, et qui comprend une première entrée agencée pour être entraînée par ladite sortie dudit premier engrenage correcteur. Elle comprend également une seconde entrée destinée à être entraînée manuellement par pas, et une sortie agencée pour entraîner un deuxième organe d'affichage d'une deuxième indication liée au temps, telle que les heures.According to the invention, the display device also comprises a second correcting gear, which may be similar to or different from said first corrective gear, and which comprises a first input arranged to be driven by said output of said first corrective gear. It also comprises a second input intended to be manually driven in steps, and an output arranged to drive a second display member of a second indication related to time, such as hours.

Par conséquent, trois choix se présentent à l'utilisateur pour corriger l'affichage : soit toutes les indications de manière continue par l'intermédiaire dudit dispositif de correction principal, soit au niveau du premier correcteur, qui corrige ainsi la première indication par pas et entraîne en conséquence la seconde indication, ou finalement exclusivement au niveau de la seconde indication. Cette dernière correction ne corrige que la seconde indication, sans influencer la première, et permet donc de maintenir l'indexation des indications.Therefore, there are three choices for the user to correct the display: either all indications continuously via said main correction device, or at the first corrector, which thus corrects the first indication by steps and accordingly causes the second indication, or ultimately exclusively at the second indication. This last correction corrects only the second indication, without influencing the first one, and thus makes it possible to maintain the indexation of the indications.

Avantageusement, au moins l'un (ou même chacun) des engrenages correcteurs comprend une roue d'entrée montée folle sur un axe et faisant office de première entrée, ledit axe (ou une roue solidaire en rotation avec ce dernier) faisant office de sortie, une étoile, une roue à dent de scie ou toute autre denture appropriée montée solidaire en rotation dudit axe, ladite étoile respectivement roue à dent de scie faisant office de deuxième entrée, et un sautoir reliant ladite roue d'entrée et ladite étoile respectivement ladite roue à dent de scie. L'étoile, ou la roue à dent de scie, le cas échéant, est agencée pour être pivotée manuellement par pas discrets par rapport à ladite roue d'entrée afin de pouvoir corriger l'indication correspondante par pas, par exemple au moyen d'un levier, d'un crochet, ou d'un doigt d'un mobile. Un système de correction pas-à-pas simple et compact est ainsi proposé en tant qu'engrenage correcteur.Advantageously, at least one (or even each) of the corrective gears comprises an input wheel mounted idle on an axis and acting as a first input, said axis (or a wheel integral with the latter) acting as an output a star, a sawtooth wheel or any other suitable toothing mounted to rotate with said axis, said star respectively sawtooth wheel acting as a second input, and a jumper connecting said input wheel and said star respectively said sawtooth wheel. The star, or the sawtooth wheel, if any, is arranged to be manually pivoted in discrete steps with respect to said input wheel in order to be able to correct the corresponding indication in steps, for example by means of a lever, a hook, or a finger of a mobile. A simple and compact step-by-step correction system is thus proposed as a correction gear.

Alternativement, au moins l'un des engrenages correcteurs comprend un engrenage différentiel comprenant :

  • un premier mobile d'entrée faisant office de première entrée, qui comprend par exemple une première roue solaire ;
  • un deuxième mobile d'entrée en liaison cinématique avec une étoile ou une roue à dent de scie et faisant office de deuxième entrée, ledit deuxième mobile d'entrée comprenant par exemple une deuxième roue solaire ;
  • un sautoir destiné à être monté sur un élément fixe tel qu'un élément de bâti et agencé pour positionner angulairement ladite étoile, respectivement ladite roue à dent de scie, par rapport audit élément fixe ;
  • une sortie en liaison cinématique avec chacun desdits mobiles d'entrée, comprenant par exemple un porte-satellite portant au moins un pignon satellite engrenant avec chacun des premiers et deuxièmes mobiles d'entrée.
Alternatively, at least one of the corrective gears comprises a differential gear comprising:
  • a first input mobile acting as a first input, which comprises for example a first sun gear;
  • a second input mobile in kinematic connection with a star or a sawtooth wheel and acting as a second input, said second input mobile comprising for example a second sun gear;
  • a jumper intended to be mounted on a fixed element such as a frame member and arranged to angularly position said star, respectively said sawtooth wheel, with respect to said fixed element;
  • an output in kinematic connection with each of said input mobiles, comprising, for example, a satellite carrier carrying at least one planet gear meshing with each of the first and second input mobiles.

Avantageusement, un organe d'affichage, tel qu'une aiguille, un disque ou similaire, est porté directement par un axe solidaire en rotation de ladite sortie, par exemple dudit porte-satellite. Aucun élément intermédiaire n'est ainsi nécessaire.Advantageously, a display member, such as a needle, a disk or the like, is carried directly by an axis integral in rotation with said output, for example from said carrier. No intermediate element is thus necessary.

Avantageusement, ladite étoile respectivement ladite roue à dent de scie est solidaire en rotation dudit deuxième mobile d'entrée, par exemple de ladite deuxième roue solaire. Une construction simple et compacte est ainsi proposée.Advantageously, said star respectively said sawtooth wheel is integral in rotation with said second input mobile, for example said second sun gear. A simple and compact construction is thus proposed.

Avantageusement, ledit dispositif de correction principal, qui comprend par exemple une tige de mise à l'heure, un fond tournant, une lunette tournante ou tout autre élément permettant de réaliser cette fonction, est agencé pour entraîner sélectivement ledit premier engrenage par l'intermédiaire d'un embrayage, qui peut être agencé pour être embrayé par l'intermédiaire d'un organe de commande supplémentaire.Advantageously, said main correction device, which comprises for example a time-setting rod, a rotating bottom, a rotating bezel or any other element making it possible to perform this function, is arranged to selectively drive said first gear via a clutch, which can be arranged to be engaged via an additional control member.

L'invention porte également sur un mouvement d'horlogerie comprenant un dispositif d'affichage comme défini ci-dessus, ainsi qu'une pièce d'horlogerie comprenant un tel mouvement.The invention also relates to a watch movement comprising a display device as defined above, as well as a timepiece comprising such a movement.

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

Dans la description qui suit, des structures similaires sont représentées par les mêmes signes de référence afin de faciliter la compréhension.In the following description, similar structures are represented by the same reference signs to facilitate understanding.

La figure 1 illustre schématiquement le principe de l'invention dans le contexte d'un mouvement d'horlogerie 1. Ce mouvement 1 comporte, comme généralement connu, un organe moteur 3 en liaison cinématique avec un organe réglant 5, par l'intermédiaire d'un rouage de finissage 7. L'organe réglant 5 peut être par exemple un ensemble balancier-spiral classique associé à un échappement quelconque, un tourbillon, un carrousel, un volant inertiel ou même un organe réglant électronique ou électromécanique. De façon similaire, l'organe moteur 3 peut être un ressort moteur stocké dans un barillet, un moteur électrique ou similaire.The figure 1 schematically illustrates the principle of the invention in the context of a watch movement 1. This movement 1 comprises, as generally known, a motor member 3 in kinematic connection. with a regulating member 5, via a finishing train 7. The regulating member 5 may be for example a conventional balance-sprung assembly associated with any escapement, a whirlpool, a carousel, an inertial flywheel or even an electronic or electromechanical regulating organ. Similarly, the motor member 3 may be a motor spring stored in a barrel, an electric motor or the like.

L'organe moteur 3 entraîne également un dispositif d'affichage 9 selon l'invention. Ce dispositif d'affichage comporte un premier engrenage 11, entraîné par l'organe moteur 3 par l'intermédiaire d'un mobile à friction 13. Le mobile à friction 13 sert à débrayer l'organe moteur du premier engrenage 11 lorsque ce dernier est entraîné par un dispositif de correction principal 15, comme par exemple une tige de mise à l'heure, une lunette ou un fond tournant(e) ou similaire. Le dispositif de correction principal 15 est sélectivement lié cinématiquement au premier engrenage 11 par l'intermédiaire d'un rouage de mise à l'heure 16 lorsqu'un embrayage 18 est engagé sous la commande d'un actuateur 17. L'embrayage 18 peut être par exemple un système à tirette actionné en tirant sur une tige de mise à l'heure (la tige elle-même faisant également office d'actuateur 17 dans un tel cas), un pignon coulant 18a ou pignon basculant actionné par un actuateur supplémentaire tel qu'une targette, un poussoir, ou similaire.The motor unit 3 also drives a display device 9 according to the invention. This display device comprises a first gear 11, driven by the motor member 3 via a friction wheel 13. The friction wheel 13 serves to disengage the motor member of the first gear 11 when the latter is driven by a main correction device 15, such as a time-setting rod, a telescope or a rotating bottom (e) or the like. The main correction device 15 is selectively kinematically linked to the first gear 11 by means of a time-setting train 16 when a clutch 18 is engaged under the control of an actuator 17. The clutch 18 may for example, a pull-rod system actuated by pulling on a time-setting rod (the rod itself also acting as an actuator 17 in such a case), a sliding pinion 18a or rocking pinion actuated by an additional actuator such as a bolt, a pusher, or the like.

Par ailleurs, le mobile à friction 13 peut être substitué par un engrenage différentiel ou par un embrayage classique du type communément utilisé dans un mécanisme de chronographe.In addition, the friction wheel 13 may be substituted by a differential gear or a conventional clutch of the type commonly used in a chronograph mechanism.

Par conséquent, une manipulation du dispositif de correction principal 15 agit sur tout le dispositif d'affichage 9 qui se situe en aval du mobile à friction 13, et permet une correction de l'organe d'affichage de façon « classique », c'est-à-dire de manière continue, en maintenant l'indexation du dispositif.Therefore, a manipulation of the main correction device 15 acts on the entire display device 9 which is located downstream of the friction wheel 13, and allows a correction of the display member in a "conventional" manner, it that is to say continuously, maintaining the indexing of the device.

En aval du mobile à friction 13 se trouve un premier engrenage correcteur 19, comprenant deux entrées 19a, 19b et une sortie 19c. La première de ces entrées 19a est en liaison cinématique avec le premier engrenage 11, tandis que l'autre entrée 19b est agencée pour être entraîné de manière pas-à-pas suite à une action d'un utilisateur (par exemple au moyen d'un poussoir représenté schématiquement par la flèche à extrémité arrondie) par l'intermédiaire d'un premier correcteur pas-à-pas 21. Ce correcteur pas-à-pas 21, également connu sous le nom « correcteur rapide », permet de corriger une indication par pas, typiquement correspondant à une division de la quantité indiquée par l'organe d'affichage y associé.Downstream of the friction wheel 13 is a first corrective gear 19, comprising two inputs 19a, 19b and an output 19c. The first of these inputs 19a is in kinematic connection with the first gear 11, while the other input 19b is arranged to be driven step-by-step following an action by a user (for example by means of a pusher shown schematically by the arrow with rounded end) via a first corrector step-by-step 21. This corrector step-by-step 21, also known as "fast corrector", corrects a step indication, typically corresponding to a division of the amount indicated by the associated display member.

Le premier engrenage correcteur 19 peut être un engrenage différentiel, comme représenté schématiquement sur les figures 1 et 3, et incorporé dans le mode de réalisation concret exposé ci-dessous en lien avec les figures 4 à 6. Alternativement cet engrenage correcteur 19 peut être un mobile correcteur du type illustré schématiquement et sous forme simplifiée sur la figure 2.The first correcting gear 19 may be a differential gear, as shown schematically on the figures 1 and 3 , and incorporated in the concrete embodiment set out below in connection with the Figures 4 to 6 . Alternatively this correction gear 19 may be a corrective mobile of the type illustrated schematically and in simplified form on the figure 2 .

Le mobile correcteur 19 de la figure 2 comprend un axe de rotation 25 sur lequel est monté fou un mobile d'entrée 27, entraîné par ledit premier engrenage 11 et servant en tant que première entrée 19a. Le mobile d'entrée 27 est lié cinématiquement à une étoile 29 (ou similaire) par l'intermédiaire d'un sautoir 31, ladite étoile 29 faisant office de deuxième entrée 19b. Alternativement, l'étoile peut être substituée par une roue à dent de scie (voir ci-dessous). Ce sautoir permet à la roue d'entrée 27 d'entraîner l'étoile 29 lorsque le couple exercé entre ces deux derniers est inférieure à une valeur prédéterminée. L'étoile 29 ainsi qu'une roue de sortie 33 sont solidaires en rotation de l'axe 25, cette dernière entraînant directement ou indirectement un premier organe d'affichage 23. Par exemple, le premier organe d'affichage 23 peut être porté directement par l'axe 25, qui sert également donc de sortie 19c, ou peut être entraîné par l'intermédiaire de ladite roue de sortie 33. Dans le contexte de la présente invention, le premier organe d'affichage 23 peut indiquer les minutes de l'heure, mais toute autre indication liée au temps est également possible. La roue de sortie 33 peut être omise si elle est superflue.The corrective mobile 19 of the figure 2 comprises an axis of rotation 25 on which is mounted crazy an input mobile 27, driven by said first gear 11 and serving as a first input 19a. The input mobile 27 is kinematically linked to a star 29 (or similar) via a jumper 31, said star 29 acting as a second input 19b. Alternatively, the star can be substituted by a sawtooth wheel (see below). This jumper allows the input wheel 27 to drive the star 29 when the torque exerted between the latter two is less than a predetermined value. The star 29 and an output wheel 33 are integral in rotation with the axis 25, the latter driving directly or indirectly a first display member 23. For example, the first display member 23 can be carried directly by the axis 25, which also serves as an output 19c, or can be driven through said output wheel 33. In the context of the present invention, the first display member 23 may indicate the minutes of the time, but any other indication related to time is also possible. The output wheel 33 can be omitted if it is superfluous.

Afin de faire pivoter l'étoile 29 par rapport au mobile d'entrée 27 à raison d'un pas, le premier correcteur pas-à-pas 21 comprend une bascule 35 monté en pivotement sur un élément de bâti (non illustré), ladite bascule 35 étant commandée par un organe de commande 37 quelconque (par exemple un bouton poussoir, une targette ou similaire). Alternativement, la bascule 35 peut être remplacée par un doigt d'actionnement porté par un mobile tournant. Lorsque l'utilisateur actionne l'organe de commande 37, l'extrémité de la bascule 35 pénètre dans la denture de l'étoile 29 afin de la faire pivoter de telle sorte qu'elle surmonte l'effet du sautoir 31, qui retombe dans l'interstice suivant entre deux dents afin de repositionner l'étoile 29 par rapport au mobile d'entrée 27. Ce faisant, l'axe 25 ainsi que la roue de sortie 33 pivotent d'un pas angulaire correspondant à celui de la denture de l'étoile 29. L'indication de l'organe d'affichage 23 correspondant, et celui de tout organe d'affichage 61 en aval dans la chaîne cinématique, est ainsi modifiée. Dans le cas où l'étoile a été substituée par une roue à dent de scie, ladite bascule 35 peut comporter un crochet agencé pour l'entraînement de ladite roue, de manière connue.In order to pivot the star 29 relative to the input mobile 27 by one step, the first step-by-step corrector 21 comprises a flip-flop 35 pivotally mounted on a frame member (not shown), said flip-flop 35 being controlled by any control member 37 (for example a push button, a bolt or the like). Alternatively, the rocker 35 can be replaced by an actuating finger carried by a rotating wheel. When the user actuates the control member 37, the end of the lever 35 enters the teeth of the star 29 in order to rotate so that it overcomes the effect of the jumper 31, which falls into the next gap between two teeth to reposition the star 29 relative to the input mobile 27. In doing so, the axis 25 and that the output wheel 33 pivot angularly corresponding to that of the toothing of the star 29. The indication of the corresponding display member 23, and that of any display member 61 downstream in the kinematic chain, is thus modified. In the case where the star has been substituted by a sawtooth wheel, said lever 35 may comprise a hook arranged for driving said wheel, in known manner.

Le sautoir 31 débrayant la roue d'entrée 27 de l'étoile 29 au moment de la correction rapide, une opération du premier correcteur pas-à-pas 21 n'a que très peu, voire pas, d'influence en amont de ladite roue d'entrée 27.The jumper 31 disengaging the input wheel 27 of the star 29 at the time of rapid correction, an operation of the first step-by-step corrector 21 has very little, if any, influence upstream of said input wheel 27.

Par contre, si l'utilisateur embraye le dispositif de correction principal 15 et le pivote, le premier engrenage correcteur 19 sert de renvoi, sa seconde entrée restant inactive puisque l'étoile 29 est maintenue solidaire en rotation du mobile d'entrée 27 par l'intermédiaire du sautoir 31. Ce pivotement entraînera donc un réglage en continu du premier organe d'affichage 23, ainsi que tout organe d'affichage 61 en aval du premier engrenage correcteur 19.On the other hand, if the user engages the main correction device 15 and pivots it, the first corrective gear 19 serves as a deflection, its second input remaining inactive since the star 29 is kept rotationally fixed to the input mobile 27 by the This pivoting will thus result in a continuous adjustment of the first display member 23, as well as any display member 61 downstream of the first correction gear 19.

La figure 3 illustre schématiquement et sous forme simplifiée une variante du premier engrenage correcteur 19 qui comprend un engrenage différentiel 41. Dans cette variante, l'engrenage différentiel 41 est sphérique, mais peut également être plat, tous les axes de rotation des éléments pivotants étant mutuellement parallèles et perpendiculaire au plan de l'engrenage différentiel.The figure 3 illustrates schematically and in simplified form a variant of the first correction gear 19 which comprises a differential gear 41. In this variant, the differential gear 41 is spherical, but can also be flat, all the axes of rotation of the pivoting elements being mutually parallel and perpendicular to the plane of the differential gear.

La première entrée 19a est constituée par un premier mobile d'entrée comprenant une roue solaire 43, qui est entraînée par ledit premier engrenage 11, et est munie d'une denture à cet effet. La seconde entrée 19b est constituée par un deuxième mobile d'entrée comprenant une deuxième roue solaire 45, qui est solidaire en rotation d'une étoile 47. Comme ci-dessus, l'étoile 47 peut être remplacée par une roue à dent de scie, le cas échéant.The first input 19a is constituted by a first input mobile comprising a sun gear 43, which is driven by said first gear 11, and is provided with a toothing for this purpose. The second input 19b is constituted by a second input mobile comprising a second sun gear 45, which is integral in rotation with a star 47. As above, the star 47 can be replaced by a sawtooth wheel where appropriate.

L'étoile 47 est positionnée dans l'une de ses positions angulaires discrètes par l'intermédiaire d'un sautoir 31, monté sur un élément fixe du bâti 49.The star 47 is positioned in one of its discrete angular positions by means of a jumper 31, mounted on a fixed element of the frame 49.

La sortie 19c de l'engrenage différentiel 41 est formée par un porte-satellite 51, qui porte un ou plusieurs satellites 53 de façon connue, ces derniers engrenant de part et d'autre avec lesdites roues solaires 43, 45. Le porte-satellite 51 est solidaire en rotation d'un axe 25, qui peut être solidaire en rotation dudit premier organe d'affichage 23.The output 19c of the differential gear 41 is formed by a planet carrier 51, which carries one or more satellites 53 in a known manner, the latter meshing on either side with the said sun wheels 43, 45. The planet carrier 51 is integral in rotation with an axis 25, which can be fixed in rotation with said first display member 23.

Lors du fonctionnement normal du dispositif d'affichage 9, l'étoile 47 reste immobile par rapport au bâti 49. Afin d'effectuer une correction rapide, le premier correcteur pas-à-pas 21 comprend une bascule 35, commandée par un organe de commande 37 quelconque (par exemple un bouton poussoir, une targette ou similaire), qui fait pivoter l'étoile 47 par rapport au bâti 49. Lorsque l'utilisateur actionne l'organe de commande 37, l'extrémité de la bascule 35 pénètre dans la denture de l'étoile 47 afin de la faire pivoter de telle sorte qu'elle surmonte l'effet du sautoir 31, qui retombe par la suite dans le prochain interstice entre deux dents afin de repositionner l'étoile 47 par rapport au bâti 49. Ce faisant, le porte-satellite 51 ainsi que l'axe 25 pivotent d'un pas angulaire correspondant à la moitié de celle de la denture de l'étoile 47, puisque la première entrée 19a peut être considérée comme étant quasi-immobile par rapport à la vitesse de rotation de la deuxième entrée 19b. L'indication de l'organe d'affichage 23 correspondant, et celui de tout organe d'affichage 39 en aval dans la chaîne cinématique, est ainsi modifiée, et les composants en amont ne sont pas influencés par cette correction. Comme c'est le cas pour la figure 2, dans le cas où l'étoile a été substituée par une roue à dent de scie, ladite bascule 35 peut comporter un crochet agencé pour l'entraînement de ladite roue, de manière connue.During normal operation of the display device 9, the star 47 remains stationary with respect to the frame 49. In order to effect a rapid correction, the first step-by-step corrector 21 comprises a rocker 35, controlled by a control member. any control 37 (eg a push button, a bolt or the like), which rotates the star 47 relative to the frame 49. When the user actuates the control member 37, the end of the lever 35 enters the toothing of the star 47 to rotate it so that it overcomes the effect of the jumper 31, which then falls back into the next interstice between two teeth to reposition the star 47 relative to the frame 49 In doing so, the planet carrier 51 as well as the axis 25 pivot with an angular pitch corresponding to half that of the toothing of the star 47, since the first inlet 19a can be considered to be quasi-immobile by ratio to the speed of rotation of the two xth entry 19b. The indication of the corresponding display member 23 and that of any display member 39 downstream in the kinematic chain is thus modified, and the upstream components are not influenced by this correction. As is the case for figure 2 , in the case where the star has been substituted by a sawtooth wheel, said rocker 35 may comprise a hook arranged for driving said wheel, in known manner.

Par contre, si l'utilisateur embraye le dispositif de correction principal 15 et le pivote, l'engrenage différentiel constituant le premier engrenage correcteur 19 sert de renvoi, car sa seconde entrée reste immobile. Ce pivotement entraînera donc un réglage en continu du premier organe d'affichage 23 avec une réduction de vitesse de rotation d'un facteur de deux.On the other hand, if the user engages the main correction device 15 and pivots it, the differential gear constituting the first correction gear 19 serves as a return gear because its second input remains stationary. This pivoting will therefore result in a continuous adjustment of the first display member 23 with a reduction in speed of rotation by a factor of two.

Revenant maintenant sur la figure 1 et continuant en aval le long du rouage, la sortie 19c du premier engrenage correcteur 19 entraîne un deuxième rouage 55, qui est lié cinématiquement à une première entrée 57a d'un deuxième engrenage correcteur 57, de forme similaire audit premier engrenage correcteur 19, mutatis mutandis, par exemple selon l'une des variantes schématiques des figures 2 et 3. La deuxième entrée 57b de ce deuxième engrenage correcteur 57 est en liaison cinématique avec un deuxième correcteur pas-à-pas 59, similaire du premier 23. Finalement, la sortie 57c du deuxième engrenage correcteur 57 entraîne directement ou indirectement un deuxième organe d'affichage 61. Dans le cas où le deuxième engrenage correcteur 57 reprend la forme de la figure 2 et le deuxième organe d'affichage 61 est solidaire en rotation de l'axe 25, aucune roue de sortie 33 n'est nécessaire si le rouage se termine par cet organe d'affichage 61.Returning now to the figure 1 and continuing downstream along the train, the output 19c of the first correction gear 19 drives a second gear train 55, which is kinematically connected to a first input 57a of a second correction gear 57, similar in shape to the first gear 57 correction gear 19, mutatis mutandis, for example according to one of the schematic variants of Figures 2 and 3 . The second input 57b of this second correction gear 57 is in kinematic connection with a second corrective step-by-step 59, similar to the first 23. Finally, the output 57c of the second correction gear 57 drives directly or indirectly a second display member 61. In the case where the second correction gear 57 resumes the shape of the figure 2 and the second display member 61 is integral in rotation with the axis 25, no output wheel 33 is necessary if the train ends with this display member 61.

Les figures 4 à 6 représentent schématiquement un mode de réalisation concret d'un dispositif d'affichage 9 selon l'invention. Ce mode de réalisation utilise des engrenages correcteurs 19, 57 constitués par des engrenages différentiels selon la figure 3, mais les modifications nécessaires pour utiliser des engrenages correcteurs 19, 57 selon la figure 2 sont à la portée de l'homme du métier. Par ailleurs, il est également possible d'intégrer l'un de chaque type d'engrenage correcteur 19, 57, le cas échéant.The Figures 4 to 6 schematically represent a concrete embodiment of a display device 9 according to the invention. This embodiment uses corrective gears 19, 57 constituted by differential gears according to the figure 3 , but the necessary modifications to use corrective gears 19, 57 according to the figure 2 are within the reach of the skilled person. Furthermore, it is also possible to integrate one of each type of corrective gear 19, 57, where appropriate.

Un organe moteur 3 entraîne le premier rouage 11 par l'intermédiaire d'un mobile à friction 13. Ce mobile à friction 13 comprend, d'une part, une roue à friction 13a engrenant avec une denture de tambour 3a de l'organe moteur, et d'autre part un pignon 13b. Ce dernier entraîne ledit premier rouage 11, et est également en liaison cinématique avec un rouage de mise à l'heure 16. Ce dernier est en liaison cinématique sélectif avec une tige de mise à l'heure 15 par l'intermédiaire d'un embrayage comprenant un pignon coulant 18a. Ce pignon coulant 18a engrène sélectivement avec une roue 16a faisant partie dudit rouage de mise à l'heure 16, sa position le long de la tige de mise à l'heure 15 étant commandé par un levier 17 mené par un organe de commande (non illustré) tel qu'un poussoir, une targette ou similaire.A driving member 3 drives the first gear 11 via a friction wheel 13. This friction mobile 13 comprises, on the one hand, a friction wheel 13a meshing with a toothing drum 3a of the drive member and on the other hand a pinion 13b. The latter drives said first gear 11, and is also in kinematic connection with a time setting wheel 16. The latter is in kinematic selective connection with a time setting rod 15 via a clutch comprising a sliding pinion 18a. This sliding pinion 18a meshes selectively with a wheel 16a forming part of said time-setting train 16, its position along the time-setting rod 15 being controlled by a lever 17 driven by a control member (not shown). illustrated) such as a pusher, a bolt or the like.

Lorsque le pignon coulant 18a est embrayé, l'utilisateur peut entraîner le premier rouage 11, qui assure la correction des organes d'affichage de manière continue, la friction 13 évitant une application d'un couple néfaste sur le rouage de finissage (non illustré), qui est également entraîné par l'organe moteur 3.When the sliding pinion 18a is engaged, the user can drive the first gear 11, which ensures the correction of the display members in a continuous manner, the friction 13 avoiding application of a harmful torque on the finishing train (not shown), which is also driven by the driving member 3.

En suivant le premier rouage 11 dans le sens aval, sa dernière roue engrène avec un premier mobile d'entrée 19a du premier engrenage correcteur 19. Dans la variante illustrée, le premier engrenage correcteur 19 est un engrenage à différentiel sphérique. Il va sans dire que d'autres constructions d'engrenage à différentiel (planaire, conique, ...) sont également possibles. Tel qu'illustré, cet engrenage à différentiel comprend un premier mobile d'entrée comprenant une première roue solaire à denture de chant, un second mobile d'entrée 19b comprenant une deuxième roue solaire également à denture de chant, et un mobile de sortie 19c comportant un porte-satellite. Comme généralement connu, le porte-satellite porte au moins un pignon satellite (caché sur les figures par d'autres éléments) engrenant de part et d'autre avec les dentures de chant respectives des deux roues solaires. Le porte-satellite est solidaire en rotation d'un axe 19d, qui peut porter directement un premier organe d'affichage 23. Alternativement, cet organe d'affichage 23 peut se trouver sur un autre mobile de telle sorte qu'il est entraîné par l'axe 19d ou le mobile de sortie 19c. Dans la variante illustrée, le porte-satellites du mobile de sortie 19c est muni d'une denture périphérique, mais une autre roue, solidaire en rotation de l'axe 19d et/ou du mobile de sortie 19c peut être prévue.Following the first gear 11 in the downstream direction, its last wheel meshes with a first input mobile 19a of the first correction gear 19. In the variant shown, the first corrective gear 19 is a spherical differential gear. It goes without saying that other gear constructions with differential (planar, conical, ...) are also possible. As illustrated, this differential gear comprises a first input mobile comprising a first sun gear with side teeth, a second input mobile 19b comprising a second sun gear also toothed, and an output mobile 19c having a satellite carrier. As is generally known, the carrier carries at least one satellite gear (hidden in the figures by other elements) meshing with each other with the respective edge teeth of the two sun wheels. The planet carrier is integral in rotation with an axis 19d, which can directly carry a first display member 23. Alternatively, this display member 23 can be on another mobile so that it is driven by the axis 19d or the mobile output 19c. In the variant shown, the planet carrier of the output mobile 19c is provided with a peripheral toothing, but another wheel, integral in rotation with the axis 19d and / or the mobile output 19c may be provided.

Le deuxième mobile d'entrée 19b est solidaire en rotation d'une roue à dent de scie 47a, qui est positionnée angulairement par l'intermédiaire d'un sautoir 31 a fixé sur le bâti (non illustré). Alternativement, la roue à dent de scie peut être remplacée par une étoile. Encore alternativement, la roue à dent de scie 47a (ou l'étoile, le cas échéant) peut se trouver sur un autre mobile en liaison cinématique avec ledit deuxième mobile d'entrée 19b. Dans la variante illustrée, le premier organe d'affichage 23 indique les minutes, et par conséquent la roue à dent de scie 47a comporte 30 dents, afin de pouvoir modifier la position angulaire du premier organe d'affichage 23 par pas de 1/60ème d'un tour.The second input movable 19b is rotationally secured to a sawtooth wheel 47a, which is angularly positioned by means of a jumper 31a fixed to the frame (not shown). Alternatively, the sawtooth wheel can be replaced by a star. Still alternatively, the sawtooth wheel 47a (or the star, if any) may be on another mobile in kinematic connection with said second input mobile 19b. In the variant shown, the first display member 23 indicates the minutes, and therefore the sawtooth wheel 47a has 30 teeth, in order to be able to modify the angular position of the first display member 23 in steps of 1/60 th of a round.

Lors du fonctionnement normal du dispositif d'affichage 9, la roue à dent de scie 47a reste immobile, et le premier engrenage correcteur 19 sert en tant que renvoi, le premier organe d'affichage 23 est entraîné normalement par l'organe moteur et/ou par le dispositif de correction principal 15 en cas de correction de manière continue.During normal operation of the display device 9, the sawtooth wheel 47a remains stationary, and the first correcting gear 19 serves as a deflection, the first display member 23 is driven normally by the motor unit and / or by the main correction device 15 in case of correction in a continuous manner.

Le dispositif d'affichage 9 comprend également une bascule 35a servant de premier correcteur pas-à-pas 21. Comme clairement visible sur les figures 4 et 5, si la bascule 35a est pivotée de telle sorte que son extrémité libre pénètre dans la denture de la roue à dent de scie 47a, cette dernière est pivotée d'un pas par rapport au bâti, et est repositionnée dans sa nouvelle position angulaire par l'intermédiaire du sautoir 31 a. Par conséquent, le mobile de sortie 19c est avancé d'un pas d'un angle représentant la moitié du pas angulaire de la dent de scie, comme expliqué ci-dessus.The display device 9 also comprises a flip-flop 35a serving as a first step-by-step corrector 21. As clearly visible on the Figures 4 and 5 if the rocker 35a is pivoted so that its free end enters the toothing of the sawtooth wheel 47a, the latter is pivoted one step relative to the frame, and is repositioned in its new angular position by the intermediate of the jumper 31 a. Therefore, the output mobile 19c is advanced by one step of an angle representing half the angular pitch of the sawtooth, as explained above.

Le mobile de sortie 19c entraîne également le deuxième rouage 55. Par conséquent, non seulement une correction par l'intermédiaire du dispositif de correction principal 15, mais aussi une correction pas-à-pas par l'intermédiaire de la bascule 35a est transmise à ce deuxième rouage 55.The output mobile 19c also drives the second train 55. Therefore, not only a correction via the main correction device 15, but also a step-by-step correction via the flip-flop 35a is transmitted to this second wheel 55.

Le deuxième rouage 55 conduit vers le deuxième engrenage correcteur 57, qui est de construction similaire audit premier engrenage correcteur 19, et est reproduit à échelle agrandie sur la figure 5.The second gear train 55 leads to the second correcting gear 57, which is of similar construction to said first correcting gear 19, and is reproduced on an enlarged scale on the figure 5 .

Le mobile d'entrée 57a est entraînée par le deuxième rouage 55, et la deuxième entrée 57b est solidaire en rotation d'une étoile 47b, pour laquelle les mêmes commentaires émis ci-dessus dans le cadre de la roue à dent de scie 47a s'appliquent mutatis mutandis. Puisque le deuxième organe d'affichage 61 affiche les heures dans le mode de réalisation illustré, l'étoile 47b comporte six sommets, afin de pouvoir modifier la position angulaire du deuxième organe d'affichage par pas de 1/12ème d'un tour. Cette étoile 47b est également positionnée angulairement par l'intermédiaire d'un sautoir 31 b, solidaire d'un élément fixe (non illustré), et peut être entraîné en rotation par pas par une action de l'utilisateur sur une bascule 35b dont l'extrémité libre peut pénétrer dans la denture de l'étoile 47b afin de l'avancer d'un pas de manière connue.The input mobile 57a is driven by the second gear 55, and the second input 57b is integral in rotation with a star 47b, for which the same comments issued above in the context of the sawtooth wheel 47a apply mutatis mutandis. Since the second display element 61 displays the hour in the illustrated embodiment, the star 47b has six vertices, to modify the angular position of the second display member by steps of 1/12 of a turn . This star 47b is also positioned angularly via a jumper 31b, integral with a fixed element (not shown), and can be rotated by steps by an action of the user on a rocker 35b whose free end can penetrate into the toothing of the star 47b to advance a step in a known manner.

De manière semblable au premier organe d'affichage 23, le deuxième organe d'affichage 61 est solidaire en rotation d'un axe 57d, lui-même solidaire en rotation du porte-satellites 57c qui fait office de mobile de sortie. À nouveau, cet organe d'affichage 61 peut alternativement se trouver sur un mobile distinct, entraîné directement ou indirectement par le porte-satellite 57c.In a manner similar to the first display member 23, the second display member 61 is rotatably connected to an axis 57d, itself rotationally integral with the planet carrier 57c which serves as an output mobile. Again, this display member 61 may alternatively be on a separate mobile, driven directly or indirectly by the carrier 57c.

Dans cette variante, puisque le deuxième engrenage correcteur n'entraîne pas d'autres éléments du mécanisme, le porte-satellites 57c est dépourvu de denture. Par ailleurs, une correction rapide du deuxième organe d'affichage 23 n'a aucune influence sur le premier organe d'affichage 23, car ce dernier est en amont du premier dans la chaîne cinématique.In this variant, since the second corrective gear does not involve other elements of the mechanism, the planet carrier 57c is devoid of toothing. Furthermore, a rapid correction of the second display member 23 has no influence on the first display member 23, since the latter is upstream of the first in the drive train.

Plusieurs variantes de ce mode de réalisation concret sont possibles. Par exemple, l'un ou l'autre, ou même les deux des engrenages correcteurs 19, 57 peuvent être remplacé(s) par un engrenage correcteur du type représenté sur la figure 2. Des étoiles et des roues à dent de scie peuvent être utilisées de manière interchangeable pour les éléments 47a et 47b. Les bascules 35a, 35b peuvent être substituées chacune par une targette coulissante, ou même un doigt de correction monté sur un mobile tournant. Le porte-satellite 19c respectivement 57c de l'un ou plusieurs des engrenages différentiels 19, 57 peut servir en tant qu'entrée, l'une des roues solaires y associée servant en tant qu'entrée. Par ailleurs, le dispositif d'affichage 9 peut être agencé pour indiquer différentes divisions de temps, par exemple les jours de la semaine et le numéro de la semaine (par exemple selon la norme DIN), les mois, les années, les phases de lune, les marées, et de manière générale tout cycle périodique.Several variants of this concrete embodiment are possible. For example, either or both of the corrective gears 19, 57 may be replaced by a corrector gear of the type shown in FIG. figure 2 . Stars and sawtooth wheels can be used interchangeably for elements 47a and 47b. The flip-flops 35a, 35b may each be replaced by a sliding bolt or even a correction finger mounted on a rotating wheel. The planet carrier 19c respectively 57c of one or more of the differential gears 19, 57 may serve as an input, one of the associated sun wheels serving as an input. Moreover, the display device 9 can be arranged to indicate different time divisions, for example the days of the week and the number of the week (for example according to the DIN standard), the months, the years, the phases of the week. moon, tides, and in general any periodic cycle.

Bien que l'invention ait été décrite ci-dessus en lien avec des modes de réalisation spécifiques, des variantes supplémentaires sont également envisageables sans sortir de la portée de l'invention comme définie par les revendications.Although the invention has been described above in connection with specific embodiments, additional variants are also conceivable without departing from the scope of the invention as defined by the claims.
