Description

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne plus précisément un dispositif de correction d'un mécanisme d'affichage du type comportant deux organes d'affichage d'une indication de temps, dont l'un entraîne l'autre en rotation, au moins indirectement. Ces organes sont, de préférence, montés mobiles en rotation derrière un cadran muni d'un guichet.The present invention relates to the field of watchmaking. More specifically, it relates to a device for correcting a display mechanism of the type comprising two display members of a time indication, one of which drives the other in rotation, at least indirectly. These members are preferably rotatably mounted behind a dial provided with a window.

De tels mécanismes sont, par exemple, des mécanismes d'affichage d'un quantième grande date, d'un quantième annuel ou d'un quantième perpétuel. Ils comportent généralement deux organes d'affichage, par exemple un anneau muni d'une denture sur son flanc intérieur, et un disque concentrique à l'anneau, monté sur un mobile muni d'une denture. Les organes d'affichage portent, sur leur face supérieure, des indications de temps, telles que les unités et les dizaines d'un quantième, ou les quantièmes et les mois de l'année, ou encore les quantièmes et les jours de la semaine. Ils sont entraînés par pas, à des rythmes de rotation différents. Généralement, le premier d'entre eux effectue un pas par jour, tandis que le second effectue un pas par semaine, par dizaine, ou par mois. Le premier organe d'affichage, animé du rythme de rotation le plus rapide, est entraîné directement par un mobile d'entraînement. Le deuxième organe est entraîné soit indépendamment du premier, par le mobile d'entraînement et au moins une roue intermédiaire, soit dépendamment du premier, par l'intermédiaire de celui-ci.Such mechanisms are, for example, mechanisms for displaying a large date date, an annual calendar or a perpetual calendar. They generally comprise two display members, for example a ring provided with teeth on its inner side, and a disc concentric with the ring, mounted on a mobile provided with a toothing. The display members have, on their upper face, time indications, such as the units and the tens of a date, or the calendars and the months of the year, or the calendars and the days of the week. . They are driven by steps, at different rates of rotation. Generally, the first of them takes one step per day, while the second takes one step per week, per decade, or per month. The first display member, animated by the fastest rate of rotation, is driven directly by a training mobile. The second member is driven either independently of the first, by the drive wheel and at least one intermediate wheel, or depending on the first, through it.

Des dispositifs de correction de tels mécanismes d'affichage sont bien connus de l'homme de métier. On en distingue deux catégories.Correction devices for such display mechanisms are well known to those skilled in the art. There are two categories.

Une première catégorie concerne des dispositifs permettant de corriger directement le premier organe de rotation, animé du rythme de rotation le plus rapide, le second organe étant corrigé indirectement par l'intermédiaire du premier. Ce dispositif de correction ne s'applique qu'à des mécanismes d'affichage pour lesquels le second organe est entraîné par le premier. Un tel dispositif est généralement formé d'une roue de correction entraînée par la tige de remontoir et en prise avec la denture du premier organe d'affichage. La correction peut s'effectuer dans un sens ou l'autre de rotation.A first category relates to devices for directly correcting the first rotation member, animated by the fastest rate of rotation, the second member being corrected indirectly via the first. This correction device only applies to display mechanisms for which the second member is driven by the first. Such a device is generally formed of a correction wheel driven by the winding stem and engaged with the toothing of the first display member. The correction can be made in one direction or the other of rotation.

Une deuxième catégorie concerne des dispositifs permettant de corriger directement et indépendamment les deux organes d'affichage. Ce dispositif peut être adapté sur un mécanisme d'affichage tel que décrit précédemment, quel que soit le mode d'entraînement du deuxième organe d'affichage, indépendamment ou dépendamment du premier. Un tel dispositif est classiquement formé d'une roue de correction entraînée par la tige de remontoir, et d'un pignon baladeur en prise avec ladite roue de correction et mobile dans un trou oblong incurvé, de manière à pouvoir passer d'une première position stable dans laquelle ledit pignon est en prise avec la denture du premier organe d'affichage, à une deuxième position stable dans laquelle le pignon est en prise avec la denture du deuxième organe d'affichage. Le passage d'une position à l'autre se fait en inversant le sens de rotation de la tige de remontoir, chaque organe d'affichage ne pouvant être corrigé que dans un sens de rotation. Un tel dispositif est décrit dans la demande JP 2000-314778 .A second category relates to devices for directly and independently correcting the two display members. This device can be adapted to a display mechanism as described above, regardless of the driving mode of the second display member, independently or depending on the first. Such a device is conventionally formed of a wheel of correction driven by the winding stem, and a sliding pinion engaged with said correction wheel and movable in a curved oblong hole, so as to pass from a first stable position in which said pinion is engaged with the toothing of the first display member, at a second stable position in which the pinion is engaged with the toothing of the second display member. The transition from one position to another is done by reversing the direction of rotation of the winding stem, each display member being able to be corrected only in a direction of rotation. Such a device is described in the application JP 2000-314778 .

Pour un mécanisme d'affichage donné, on choisira un dispositif de correction adapté, sachant qu'en ce qui concerne les mécanismes dont l'entraînement du deuxième organe d'affichage se fait par l'intermédiaire du premier, deux possibilités existent pour le dispositif de correction.For a given display mechanism, a suitable correction device will be chosen, knowing that as regards the mechanisms for which the drive of the second display member is made via the first, two possibilities exist for the device. correction.

Le mécanisme d'affichage et son dispositif de correction étant généralement montés sur un pont commun, appelé pont de module d'affichage, celui-ci doit être adapté au dispositif d'affichage choisi. Lorsque le choix du client peut se porter sur l'une ou l'autre des catégories de dispositif de correction, le fabricant devra prévoir deux types de ponts, adaptés, respectivement, à la première et à la deuxième catégorie de dispositif de correction. Or, la multiplication du nombre de pièces à fabriquer, à stocker et à gérer renchérit les coûts de production et augmente les risques d'erreur de manipulation et de montage.The display mechanism and its correction device being generally mounted on a common bridge, called display module bridge, it must be adapted to the chosen display device. When the choice of the customer can be carried out on one or the other category of correction device, the manufacturer will have to provide two types of bridges, adapted, respectively, to the first and the second category of correction device. However, the multiplication of the number of parts to manufacture, store and manage increases the cost of production and increases the risk of error handling and assembly.

Le dispositif de correction d'un mécanisme d'affichage selon l'invention permet de pallier ces inconvénients.The correction device of a display mechanism according to the invention overcomes these disadvantages.

Plus précisément, l'invention concerne un dispositif de correction d'un mécanisme d'affichage pour pièce d'horlogerie du type comportant un premier organe d'affichage et un deuxième organe d'affichage, le premier organe étant agencé pour entraîner au moins indirectement le deuxième organe, le dispositif de correction comprenant un pignon baladeur agencé pour corriger le premier organe, dans une première position et dans un premier sens de rotation, et pour corriger le deuxième organe, dans une deuxième position et dans un deuxième sens de rotation. Selon l'invention, le dispositif de correction comporte encore des moyens de blocage du pignon baladeur dans la première position.More specifically, the invention relates to a device for correcting a display mechanism for a timepiece of the type comprising a first display member and a second display member, the first member being arranged to drive at least indirectly. the second member, the correction device comprising a sliding pinion arranged to correct the first member, in a first position and in a first direction of rotation, and to correct the second member, in a second position and in a second direction of rotation. According to the invention, the correction device further comprises means for locking the sliding pinion in the first position.

Grâce à la présence d'un élément de blocage du pignon baladeur, le dispositif de correction selon l'invention appartient à la première catégorie des dispositifs de correction décrits précédemment, mais se monte sur un pont conçu et fabriqué pour la deuxième catégorie. Il en résulte, que le dispositif selon l'invention permet de simplifier et rationnaliser la fabrication et la gestion des ponts de module d'affichage.Due to the presence of a sliding pinion locking element, the correction device according to the invention belongs to the first category of correction devices described above, but is mounted on a bridge designed and manufactured for the second category. As a result, the device according to the invention makes it possible to simplify and rationalize the manufacture and management of display module bridges.

D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suit d'un exemple de réalisation d'un dispositif de correction d'un mécanisme d'affichage selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement, en liaison avec le dessin annexé sur lequel :

Le module d'affichage d'une date représenté en figure 1 et 2, et désigné par la référence générale 10, est formé d'un mécanisme d'affichage 12 et d'un dispositif de correction 14, montés sur un pont 16. Il est destiné à équiper une montre mécanique ou électromécanique formée classiquement d'une boîte dans laquelle sont assemblés un mouvement de base comprenant une platine, un cadran muni d'un guichet, et une paire d'aiguille. Il est prévu pour prendre place entre le mouvement de base et le cadran, et comprend, à cet effet, des moyens de fixation du pont à la platine, non représentés.The date display module shown in FIGS. 1 and 2, and designated by the general reference numeral 10, is formed of a display mechanism 12 and a correction device 14, mounted on a bridge 16. is intended to equip a mechanical or electromechanical watch conventionally formed of a box in which are assembled a base movement comprising a plate, a dial provided with a window, and a pair of needle. It is intended to take place between the base movement and the dial, and comprises, for this purpose, means for fixing the bridge to the plate, not shown.

Le mécanisme d'affichage 12 comporte classiquement, monté sur la face supérieure du pont 16, un anneau de quantième 18, sur lequel sont apposées des indications de quantièmes. Dans la suite de cet exposé, on entendra, par face supérieure du pont 16, la face destinée à être orientée vers le cadran, et par face inférieure, la face opposée. L'anneau de quantième 18 coopère avec un mobile d'entraînement 20 qui l'entraîne à raison d'un pas par jour, de manière à effectuer un tour complet en 31 jours. L'anneau de quantième 18 est muni d'un ergot 22 dont la fonction sera explicitée ultérieurement.The display mechanism 12 conventionally comprises, mounted on the upper face of the bridge 16, a date ring 18, on which are affixed date indications. In the remainder of this description, the upper face of the bridge 16 will be understood to mean the face intended to face the dial, and the lower face the opposite face. The date ring 18 cooperates with a driving wheel 20 which drives it at a rate of one step per day, so as to perform a complete revolution in 31 days. The date ring 18 is provided with a pin 22 whose function will be explained later.

Le mécanisme d'affichage 12 comprend encore un disque des mois 24 sur lequel sont apposées des indications des mois. Le disque 24 est concentrique à l'anneau 18 et solidaire d'une roue des mois 26. Un mobile de renvoi 28 comporte une roue avant 30 montée sur la face supérieure du pont 16, en prise avec la roue 26. La roue 30 est, par ailleurs, disposée sur le trajet de l'ergot 22 de manière à être entraînée par l'anneau de quantième 18, d'un pas, en fin de mois.The display mechanism 12 further comprises a disc of months 24 on which are affixed indications of the months. The disk 24 is concentric with the ring 18 and integral with a wheel of the months 26. A deflection wheel 28 comprises a front wheel 30 mounted on the upper face of the bridge 16, engaged with the wheel 26. The wheel 30 is, moreover, arranged in the path of the lug 22 so as to be driven by the date ring 18, by one step, at the end of the month.

L'anneau 18 et le disque 24 sont positionnés par des sautoirs non représentés.The ring 18 and the disc 24 are positioned by not shown jumpers.

On notera que les indications de dates apposées sur l'anneau 18 et le disque 24 peuvent être de toutes natures. L'anneau 18 peut, par exemple, comporter des indications d'unités et le disque 24, des indications de dizaines, de manière à afficher une grande date. On comprendra que l'anneau 18 effectue alors un tour complet en 10 jours, et entraîne le disque 24 d'un pas, au moyen de l'ergot 22, en fin de dizaine.It will be noted that the date indications affixed to the ring 18 and the disc 24 can be of any kind. The ring 18 may, for example, include indications of units and the disk 24, indications of tens, so as to display a large date. It will be understood that the ring 18 then performs a complete revolution in 10 days, and drives the disk 24 one step, by means of the pin 22, at the end of ten.

Le trou 40 est traversant et comporte un dégagement 41 en face supérieure du pont 16. Il présente, en outre, une courbure dont le centre coïncide avec le centre de la roue de correction 32, de sorte que le pignon baladeur 38 est en prise avec celle-ci, quelle que soit sa position dans le trou 40. Dans une première position extrême désignée A, le pignon 38 est, en outre, en prise avec une denture de correction 42 de l'anneau 18.The correction device 14 is mounted on the underside of the bridge 16. It comprises, conventionally, a correction wheel 32, mounted on the bridge 16, and actuated by a sliding pinion 34 mounted on a winding stem 36. A sliding pinion 38 is slidably mounted in an oblong hole 40, formed in the bridge 16, in the vicinity of the correction wheel 32. The hole 40 is through and has a clearance 41 on the upper face of the bridge 16. It has, in addition, a curvature whose center coincides with the center of the correction wheel 32, so that the sliding pinion 38 is engaged with it, regardless of its position in the hole 40. In a first extreme position designated A, the pinion 38 is further engaged with a correction toothing 42 of the ring 18.

Le pont 16 est, par ailleurs, agencé pour pouvoir recevoir, sur sa face inférieure, une roue arrière 44, solidaire de la roue avant 30 et formant avec elle le mobile de renvoi 28. Le positionnement du trou oblong 40 et du mobile de renvoi 28 sur le pont 16, est tel, qu'en présence de la roue 44, le pignon baladeur 38 est en prise avec la roue 44 lorsqu'il occupe une deuxième position extrême désignée B, dans le trou oblong 40, à l'opposée de la position A.The bridge 16 is, moreover, arranged to be able to receive, on its lower face, a rear wheel 44, integral with the front wheel 30 and forming with it the deflection wheel 28. The positioning of the elongated hole 40 and the diverting wheel 28 on the bridge 16, is such that, in the presence of the wheel 44, the sliding pinion 38 is engaged with the wheel 44 when it occupies a second extreme position designated B, in the oblong hole 40, to the opposite from position A.

Selon l'invention, un bloqueur 46 est positionné dans le trou oblong 40, en position B, de manière à bloquer le pignon baladeur 38 dans la position A, dans laquelle il est en prise avec l'anneau 18. Ledit bloqueur 46 et le trou 40 sont représentés en coupe, suivant l'axe longitudinal du trou 40, en figure 3. Le bloqueur 46 est formé d'un pion comportant une tête 47, chassée dans le dégagement 41 et une tige 49, engagée dans le trou 40. Ainsi positionné, il s'oppose au déplacement du pignon baladeur 38 dans le trou 40, mais pas à sa rotation.According to the invention, a blocker 46 is positioned in the slot 40, in position B, so as to lock the sliding pinion 38 in the position A, in which it is engaged with the ring 18. Said blocker 46 and the hole 40 are shown in section, along the longitudinal axis of the hole 40, in Figure 3. The blocker 46 is formed of a pin having a head 47, driven into the clearance 41 and a rod 49, engaged in the hole 40. Thus positioned, it opposes the movement of the sliding pinion 38 in the hole 40, but not to its rotation.

Le fonctionnement du module d'affichage 10 ainsi décrit, est le suivant : Le mobile d'entraînement 20 effectue un tour par jour et entraîne l'anneau de quantième 18 d'un pas par jour. Lors du passage d'un quantième 31 à un quantième 1 du mois en cours, l'ergot 22 entraîne d'un pas le mobile de renvoi 28, qui lui-même entraîne d'un pas le disque 24. L'indication des mois passe au mois suivant.The operation of the display module 10 thus described is as follows: The driving wheel 20 performs one revolution per day and drives the date ring 18 one step per day. During the passage from a date 31 to a calendar 1 of the current month, the pin 22 drives with one step the mobile 28, which itself drives the disc 24 one step. The indication of the months passes to the following month.

Lorsque le mois en cours comporte moins de 31 jours, ou lors de l'arrêt de la montre, l'indication de la date est corrigée à l'aide du dispositif de correction 14. A cet effet, la tige de remontoir peut être actionnée dans un sens de rotation ou l'autre, de manière à entraîner la roue de correction 32 dans un sens ou l'autre. On se réfèrera à la figure 2 pour décrire le fonctionnement du dispositif de correction selon l'invention.When the current month is less than 31 days, or when the watch is stopped, the date indication is corrected by means of the correction device 14. For this purpose, the winding stem can be actuated in one direction of rotation or the other, so as to drive the correction wheel 32 in one direction or the other. Referring to Figure 2 to describe the operation of the correction device according to the invention.

Lorsque la roue de correction 32 tourne dans le sens antihoraire, elle entraîne le pignon baladeur 38 dans le sens horaire. Le pignon baladeur 38 est maintenu en position A dans le trou 40, d'une part par le bloqueur 46, et d'autre part par effet de couple en raison de son sens de rotation. Il entraîne l'anneau 18 vers les quantièmes croissant. Ce dernier actionne le disque des mois 24 vers les mois croissant, au moyen de l'ergot 22, et par l'intermédiaire du mobile de renvoi 28. Il est ainsi commode et rapide, dans ce sens de rotation, de corriger le passage d'un quantième 30 à un quantième 1 et d'un mois à l'autre, les mois de moins de 31 jours.When the correction wheel 32 rotates counterclockwise, it drives the sliding pinion 38 clockwise. The sliding pinion 38 is held in position A in the hole 40, on the one hand by the blocker 46, and on the other hand by torque effect because of its direction of rotation. It drives the ring 18 towards the growing dates. The latter actuates the disc of the months 24 towards the increasing months, by means of the lug 22, and by means of the diverting wheel 28. It is thus convenient and fast, in this direction of rotation, to correct the passage of a calendar 30 to a date 1 and from one month to another, the months of less than 31 days.

Lorsque la roue de correction tourne dans le sens horaire, le sens de rotation du pignon baladeur 38 est inversé, et bien qu'il tend à se déplacer en position B par effet de couple, il est maintenu en position A par le bloqueur 46. Il entraîne l'anneau 18 vers les quantièmes décroissant. Ce dernier actionne le disque des mois 24 vers les mois décroissant, au moyen de l'ergot 22, et par l'intermédiaire du mobile de renvoi 28. Ce sens de correction peut être avantageux, par exemple, lors d'un arrêt prolongé de la montre.When the correction wheel rotates clockwise, the direction of rotation of the sliding pinion 38 is reversed, and although it tends to move in position B by torque effect, it is held in position A by the blocker 46. It drives ring 18 to decreasing dates. The latter actuates the disc of the months 24 towards the decreasing months, by means of the lug 22, and by means of the deflection wheel 28. This direction of correction can be advantageous, for example, during a prolonged stop of the watch.

Le dispositif de correction 14 selon l'invention s'adapte à divers mécanismes d'affichage faisant intervenir deux organes d'affichage plans, mobiles en rotation derrière un guichet, dont l'un est entraîné en rotation au moins indirectement par le premier. Dans l'exemple qui vient d'être décrit, les organes d'affichage sont constitués d'un anneau de quantième 18, et d'un disque des mois 24 concentrique à l'anneau 18 et entraîné par ce dernier par l'intermédiaire d'un mobile de renvoi 28.The correction device 14 according to the invention adapts to various display mechanisms involving two planar display members, movable in rotation behind a window, one of which is rotated at least indirectly by the first. In the example that has just been described, the display members consist of a date ring 18, and a disc of the months 24 concentric with the ring 18 and driven by the latter via a mobile referral 28.

Les figures 4 et 5 illustrent, en variante, un dispositif de correction 14 selon l'invention associé à un mécanisme d'affichage 50 comportant un anneau de quantième 18 et un disque des mois 52 non concentrique à l'anneau 18. Comme dans l'exemple décrit précédemment, le dispositif de correction 14 et le mécanisme d'affichage 50 forment avec un pont 16, un module d'affichage 54. Le mécanisme d'affichage 50 se différencie du mécanisme 12 en ce que la roue des mois 26, solidaire du disque des mois 52, est montée sur le pont 16, non coaxiale à l'anneau 18, mais sur le trajet de l'ergot 22 de manière à être entraînée directement par l'anneau 18 au passage du quantième 31 au quantième 1. Le mobile de renvoi 28 est ainsi supprimé. L'agencement de la roue des mois 26 sur le pont 16, est prévu pour qu'une roue 44, solidaire de la roue des mois 26 mais disposée sur la face inférieure du pont 16, soit en prise avec le pignon baladeur 38 en position B. Le dispositif de correction 14 est inchangé dans sa structure et dans son fonctionnement, par rapport au dispositif de l'exemple précédent. Il permet de corriger directement, dans les deux sens de rotation, la position de l'anneau de quantième 18, et indirectement, par l'intermédiaire de l'anneau de quantième 18, la position du disque des mois 52.FIGS. 4 and 5 illustrate, alternatively, a correction device 14 according to the invention associated with a display mechanism 50 comprising a date ring 18 and a disc of the months 52 which are not concentric with the ring 18. As in FIG. the example described above, the correction device 14 and the display mechanism 50 form with a bridge 16, a display module 54. The display mechanism 50 differs from the mechanism 12 in that the wheel of the months 26, secured to the disk of the months 52, is mounted on the bridge 16, not coaxial with the ring 18, but on the path of the pin 22 so as to be driven directly by the ring 18 at the passage of the date 31 to the date 1. The moving wheel 28 is thus removed. The arrangement of the wheel of the months 26 on the bridge 16, is provided so that a wheel 44, integral with the wheel of the months 26 but disposed on the underside of the bridge 16, is engaged with the sliding pinion 38 in position B. The correction device 14 is unchanged in its structure and operation, compared to the device of the previous example. It makes it possible to directly correct, in both directions of rotation, the position of the date ring 18, and indirectly, via the date ring 18, the position of the disk of the months 52.

On se réfèrera enfin aux figures 6 et 7, qui illustrent un dispositif de correction 14 selon l'invention, associé à un mécanisme d'affichage 60 comportant deux disques d'affichage 62 et 64 non concentriques, sur lesquels sont apposées des indications de date, telles que les dizaines et les unités d'une grande date. Le disque des dizaines 64 est solidaire d'une planche 66, munie de 4 ergots 68, montée sur la face supérieure du pont 16. Le disque des unités 62 est solidaire d'un mobile 70 formé d'une première roue 72 et d'une deuxième roue 74 montées, respectivement, sur la face supérieure et la face inférieure du pont 16. Il est entraîné à raison d'un pas par jour, par un organe d'entraînement 70. Il est, par ailleurs, muni d'un doigt 76 destiné à coopérer avec les ergots 68 de manière à actionner le disque 64 en rotation, à raison d'un pas par dizaine. Le pont 16 est, en outre, prévu pour recevoir sur sa face inférieure, une roue arrière 44 solidaire de la planche 66.FIGS. 6 and 7, which illustrate a correction device 14 according to the invention, associated with a display mechanism 60 comprising two non-concentric display disks 62 and 64, on which date indications are affixed. , such as the tens and the units of a big date. The tens disk 64 is integral with a board 66, provided with 4 lugs 68, mounted on the upper face of the deck 16. The disk of the units 62 is integral with a mobile 70 formed of a first wheel 72 and a second wheel 74 mounted respectively on the upper face and the lower face of the bridge 16. It is driven at a rate of one step per day, by a drive member 70. It is, moreover, provided with a finger 76 intended to cooperate with the lugs 68 so as to actuate the disc 64 in rotation, at a rate of a step by tens. The bridge 16 is, in addition, provided to receive on its lower face, a rear wheel 44 integral with the board 66.

Le dispositif de correction 14 du mécanisme d'affichage 60, est similaire dans sa structure, au dispositif décrit en regard des figures 1 à 3. Il est agencé pour que le pignon baladeur 38 soit en prise avec la roue de correction 32 et la roue 74 dans une première position A, et avec la roue de correction 32 et la roue 44, dans une deuxième position B, à l'opposé de la position A.The correction device 14 of the display mechanism 60 is similar in structure to the device described with reference to FIGS. 1 to 3. It is arranged so that the sliding pinion 38 is engaged with the correction wheel 32 and the wheel 74 in a first position A, and with the correction wheel 32 and the wheel 44, in a second position B, opposite the position A.

Un bloqueur 46, en position B dans le trou oblong 40, permet de corriger directement, dans les deux sens de rotation, la position du disque des unités 62, et indirectement, par l'intermédiaire du disque des unités 62, la position du disque des dizaines 64.A blocker 46, in position B in the oblong hole 40, makes it possible to directly correct, in the two directions of rotation, the position of the disk of the units 62, and indirectly, via the disk of the units 62, the position of the disk dozens 64.

On a ainsi décrit un dispositif de correction d'un mécanisme d'affichage comprenant deux organes d'affichage, dont un premier entraîne le deuxième en rotation, obtenu par une transformation simple d'un dispositif existant destiné à corriger indépendamment lesdits organes d'affichage, et monté sur un pont prévu pour ce dispositif existant.Thus, a correction device for a display mechanism comprising two display members, a first of which drives the second in rotation, obtained by a simple transformation of an existing device for independently correcting said display members. , and mounted on a bridge provided for this existing device.

Il va de soi que la présente invention n'est pas limitée aux modes de réalisations qui viennent d'être décrits, et que diverses modifications et variantes simples peuvent être envisagées par l'homme de métier, sans sortir du cadre de la présente invention telle que définie par les revendications annexées.It goes without saying that the present invention is not limited to the embodiments that have just been described, and that various modifications and variants Single devices can be envisaged by those skilled in the art, without departing from the scope of the present invention as defined by the appended claims.

On notera, par exemple, que l'homme de métier pourra remplacer le pion 46 par tout autre moyen de blocage adéquat, tel qu'une pièce de forme munie d'une tige et d'un corps vissé ou clipé en face supérieure du pont 16.It will be noted, for example, that the skilled person may replace the pin 46 by any other suitable locking means, such as a piece of shape provided with a rod and a body screwed or clipped on the upper face of the bridge 16.
