MECANISME DE TRANSMISSION ENTRE DEUX PARTIES D'UNE TIGE DE MECHANISM FOR TRANSMITTING BETWEEN TWO PARTS OF A ROD OF
COMMANDE POUR MOUVEMENT HORLOGER ORDER FOR WATCHMAKING MOVEMENT
Domaine technique Technical area
[0001] La présente invention concerne un mécanisme de transmission de mouvements axiaux et rotatifs entre deux parties d'une tige d'axes décalés, pour mouvement horloger, dont une première partie est destinée à être logée au moins partiellement dans le mouvement horloger en étant agencée pour être mobile entre au moins des première et seconde positions axiales et, la seconde partie est destinée à porter une couronne à son extrémité libre, à l'extérieur du mouvement horloger. Plus particulièrement, ce mécanisme de transmission comporte un dispositif de transmission des mouvements axiaux entre les première et seconde parties, ainsi qu'une liaison cinématique entre un premier pignon solidaire en rotation de la première partie et un second pignon solidaire en rotation de la seconde partie. The present invention relates to a mechanism for transmitting axial and rotary movements between two parts of a shaft of offset axes for watch movement, a first portion is intended to be housed at least partially in the watch movement being arranged to be mobile between at least first and second axial positions and the second part is intended to carry a ring at its free end, outside the watch movement. More particularly, this transmission mechanism comprises a device for transmitting axial movements between the first and second parts, as well as a kinematic connection between a first pinion integral in rotation with the first portion and a second pinion integral in rotation with the second portion. .
Etat de la technique State of the art
[0002] Des dispositifs de ce type ont été divulgués dans l'art antérieur, en particulier dans des pièces d'horlogerie comportant un mouvement de base surmonté d'un module d'affichage additionnel, pour éviter un positionnement de la couronne de commande trop loin du plan médian de la boîte. Devices of this type have been disclosed in the prior art, in particular in timepieces comprising a basic movement surmounted by an additional display module, to prevent positioning of the control ring too much. far from the middle plane of the box.
[0003] A titre d'exemple, le brevet CH 691632 A5 décrit un mécanisme répondant aux caractéristiques ci-dessus, dans lequel chaque partie de tige porte un pignon agencé en prise avec le pignon de l'autre partie de tige. En outre, un cavalier est prévu pour maintenir les deux parties de la tige solidaires l'une de l'autre suivant la direction de leurs déplacements axiaux. Dans ce but, le cavalier est engagé dans une gorge ménagée dans chacune des deux parties de la tige, par déformation élastique. By way of example, patent CH 691632 A5 discloses a mechanism meeting the above characteristics, wherein each rod portion carries a pinion arranged in engagement with the pinion of the other rod portion. In addition, a jumper is provided to hold the two parts of the rod integral with each other in the direction of their axial movements. For this purpose, the rider is engaged in a groove in each of the two parts of the rod, by elastic deformation.
[0004] La demande de brevet EP 1 134628 A1 présente un mécanisme similaire au précédent, dans lequel le cavalier est remplacé par un bâti portant au moins un renvoi intermédiaire, ou un nombre impair de renvois
intermédiaires, afin d'assurer que les deux parties de la tige tournent dans le même sens de rotation. The patent application EP 1 134628 A1 has a mechanism similar to the previous one, in which the jumper is replaced by a frame carrying at least one intermediate return, or an odd number of references. intermediates, to ensure that both parts of the rod rotate in the same direction of rotation.
[0005] Les deux structures divulguées dans ces documents antérieurs présentent des procédés d'assemblage similaires complexes. En effet, le cavalier ou le bâti, suivant la structure considérée, ne peut être mis en place qu'après emboîtage du mouvement horloger, après que la partie de la tige présentant une extrémité à l'extérieur de la boîte ait été mise en place au travers de cette dernière. Une telle procédure d'assemblage est problématique, notamment du fait du peu d'espace à disposition pour accéder aux portions concernées des deux parties de tige. The two structures disclosed in these prior documents exhibit similar complex assembly methods. Indeed, the rider or the frame, according to the structure in question, can be put in place only after fitting the watch movement, after the part of the rod presenting an end outside the box has been put in place. through this last. Such an assembly procedure is problematic, particularly because of the limited space available to access the relevant portions of the two stem parts.
[0006] En outre, il semble que le second pignon soit assemblé à la seconde partie de la tige préalablement à l'insertion de cette dernière au travers de son logement dans la boîte. Ainsi, les dimensions de ce logement limitent celles du second pignon, ce qui peut imposer une limitation sur l'ampleur du décalage possible entre les deux parties de la tige. In addition, it seems that the second pinion is assembled to the second part of the rod prior to the insertion of the latter through its housing in the box. Thus, the dimensions of this housing limit those of the second pinion, which may impose a limitation on the magnitude of the possible offset between the two parts of the rod.
[0007] Le brevet EP 1748330 B1 propose une solution alternative aux structures qui viennent d'être exposées selon laquelle une partie de tige située intégralement dans le mouvement horloger est agencée fixe suivant sa direction longitudinale. L'autre partie de tige, portant la couronne de commande, coopère avec une tirette commandant les déplacements d'un pignon monté libre, suivant la direction axiale, sur la première partie de la tige tout en étant rendu solidaire de cette dernière en rotation par une liaison de type carré. Patent EP 1748330 B1 proposes an alternative solution to the structures which have just been exposed, according to which a portion of the rod situated entirely in the watch movement is arranged fixed in its longitudinal direction. The other rod part, carrying the control ring, cooperates with a pulling knob controlling the displacements of a free mounted pinion, in the axial direction, on the first part of the rod while being secured to the latter in rotation by a square type connection.
[0008] Cependant, il faut noter que, dans ce cas, la structure de la partie de tige située dans le mouvement est spécifique. Ainsi, il ne suffit pas, pour mettre en œuvre cette solution, d'utiliser la tige conventionnelle déjà présente dans un mouvement horloger servant de base à la réalisation d'une pièce d'horlogerie avec module additionnel. En effet, une modification complète du mécanisme de commande est nécessaire pour mettre en œuvre l'objet de ce brevet. However, it should be noted that in this case, the structure of the rod portion located in the movement is specific. Thus, it is not sufficient, to implement this solution, to use the conventional rod already present in a watch movement serving as a basis for the realization of a timepiece with additional module. Indeed, a complete modification of the control mechanism is necessary to implement the object of this patent.
Divulgation de l'invention Disclosure of the invention
[0009] Un but principal de la présente invention est de pallier les inconvénients des mécanismes de commande connus de l'art antérieur, en proposant un
mécanisme de transmission de mouvements axiaux et rotatifs entre deux parties d'une tige d'axes décalés, pour mouvement horloger, ne nécessitant qu'un minimum de modifications à apporter à un mouvement horloger existant tout en présentant une procédure d'assemblage simplifiée en référence aux mécanismes existants. A main object of the present invention is to overcome the disadvantages of the control mechanisms known from the prior art, by proposing a mechanism for transmitting axial and rotary movements between two parts of a rod of offset axes, for a watch movement, requiring only a minimum of modifications to be made to an existing watch movement while presenting a simplified assembly procedure with reference existing mechanisms.
[0010] A cet effet, la présente invention concerne plus particulièrement un mécanisme de transmission tel que défini plus haut, caractérisé par le fait qu'il comporte une tirette, destinée à assurer le maintien de la seconde partie de tige en référence au mouvement horloger et coopérant avec elle pour assurer son positionnement entre au moins des première et seconde positions axiales. Par ailleurs, la tirette est agencée pour coopérer avec le second pignon de manière à l'asservir aux mouvements axiaux de la seconde partie de la tige, au moins dans le sens allant depuis l'intérieur du mouvement horloger vers l'extérieur. For this purpose, the present invention relates more particularly to a transmission mechanism as defined above, characterized in that it comprises a pull, intended to ensure the maintenance of the second portion of the rod with reference to the watch movement and cooperating with it to ensure its positioning between at least first and second axial positions. Furthermore, the pull tab is arranged to cooperate with the second pinion so as to slave to the axial movements of the second portion of the rod, at least in the direction from the inside of the clock movement outwardly.
[001 1] Grâce à ces caractéristiques, le mécanisme de transmission selon la présente invention permet de conserver la construction de la tige de commande prévue dans le mouvement horloger de base, en ne nécessitant qu'un minimum d'adaptation, tandis que le fait que la tirette assure l'asservissement du second pignon à la partie correspondante de la tige, dans au moins un sens de ses déplacements axiaux, permet de simplifier l'assemblage de cette partie de tige en référence aux mécanismes connus de l'art antérieur. With these characteristics, the transmission mechanism according to the present invention makes it possible to preserve the construction of the control rod provided in the basic clockwork movement, while requiring only a minimum of adaptation, while the fact that the pull tab ensures the servocontrolling of the second pinion to the corresponding part of the rod, in at least one direction of its axial displacements, makes it possible to simplify the assembly of this rod part with reference to the known mechanisms of the prior art.
[0012] De manière préférée, la tirette comprend un premier doigt destiné à être disposé en appui contre le second pignon du côté le plus proche du mouvement horloger en référence au second pignon. Preferably, the pull tab comprises a first finger intended to be placed in abutment against the second pinion on the nearest side of the watch movement with reference to the second pinion.
[0013] La tirette peut comporter un second doigt destiné à être disposé en appui contre le second pignon du côté le plus éloigné du mouvement horloger en référence au second pignon. Ainsi, la tirette peut agir sur le second pignon pour l'asservir aux déplacements axiaux de la seconde partie de la tige dans les deux sens des déplacements. Le second doigt peut être agencé de manière à pouvoir coopérer en outre avec une gorge annulaire adaptée ménagée dans la seconde partie de tige, pour définir le mode de coopération entre la tirette et la seconde partie de la tige.
[0014] Selon un mode de réalisation préféré, le mécanisme peut comporter une surface de butée ménagée sur la seconde partie de tige et contre laquelle est agencé le second pignon dans sa position de service, la surface de butée étant située du côté le plus éloigné du mouvement horloger en référence au second pignon. The pull tab may comprise a second finger intended to be placed in abutment against the second pinion on the furthest side of the watch movement with reference to the second pinion. Thus, the pull tab can act on the second pinion to enslave axial movements of the second part of the rod in both directions of movement. The second finger can be arranged to cooperate further with a suitable annular groove formed in the second rod portion, to define the mode of cooperation between the zipper and the second portion of the rod. According to a preferred embodiment, the mechanism may comprise an abutment surface provided on the second rod portion and against which the second pinion is arranged in its operating position, the abutment surface being situated on the furthest side. the watch movement with reference to the second gear.
[0015] Grâce à ces caractéristiques, le second pignon peut simplement être enfilé sur la seconde partie de la tige lorsque cette dernière est disposée dans son logement, la mise en place de la tirette finissant d'assurer leur positionnement relatif de manière aisée grâce à un pré-positionnement opéré par la surface de butée. En outre, cette surface de butée permet également d'asservir le second pignon aux déplacements axiaux de la seconde partie de la tige dans la direction depuis l'extérieur vers l'intérieur du mouvement horloger. With these features, the second pinion can simply be threaded on the second portion of the rod when the latter is disposed in its housing, the establishment of the zipper ending to ensure their relative positioning easily thanks to a pre-positioning operated by the abutment surface. In addition, this abutment surface also serves to slave the second gear to the axial displacements of the second portion of the rod in the direction from the outside to the inside of the watch movement.
[0016] Suivant un mode de réalisation préféré, le dispositif de transmission des mouvements axiaux comporte des premier et second flasques portés par la première partie de tige en étant disposés de part et d'autre du premier pignon et présentant des diamètres respectifs supérieurs à celui de ce dernier, le second pignon étant engagé entre les deux flasques dans sa position engrenée avec le premier pignon. According to a preferred embodiment, the device for transmitting axial movements comprises first and second flanges carried by the first rod portion being disposed on either side of the first pinion and having respective diameters greater than that of the first pinion. of the latter, the second pinion being engaged between the two flanges in its engaged position with the first pinion.
[0017] Grâce à ces caractéristiques, la procédure d'assemblage du mécanisme selon la présente invention est très simple. Il suffit en effet de positionner le second pignon de manière qu'il soit en prise avec le premier pignon, entre les deux flasques, avant de disposer la seconde partie de la tige dans son logement, jusqu'à ce que le contact entre le second pignon et la surface de butée soit établi, puis de mettre en place la tirette. With these features, the assembly procedure of the mechanism according to the present invention is very simple. It suffices to position the second gear so that it is engaged with the first gear, between the two flanges, before disposing the second part of the rod in its housing, until the contact between the second pinion and abutment surface is established, and then set up the zipper.
[0018] Cette dernière pourra avantageusement être assemblée en référence au bâti du mouvement horloger de manière conventionnelle, par vissage. The latter may advantageously be assembled with reference to the frame of the watch movement in a conventional manner, by screwing.

Mode(s) de réalisation de l'invention Mode (s) of realization of the invention
[0025] La figure 1 représente une vue en perspective simplifiée d'un mécanisme de transmission selon un mode de réalisation préféré de la présente invention. Les figures 2a et 2b représentent respectivement des vues en coupe transversale du mécanisme de transmission de la figure 1 , dans des première et seconde configurations respectives. [0025] Figure 1 shows a simplified perspective view of a transmission mechanism according to a preferred embodiment of the present invention. Figures 2a and 2b respectively show cross sectional views of the transmission mechanism of Figure 1, in respective first and second configurations.
[0026] Le mécanisme de transmission est destiné à être implanté en association avec un mouvement horloger 1 logé dans une boîte de pièce d'horlogerie, non visible, par l'intermédiaire d'un cercle d'encageage 2. Le mouvement horloger et le cercle d'encageage ne sont que partiellement représentés en transparence pour des raisons de clarté des figures. The transmission mechanism is intended to be implanted in association with a watch movement 1 housed in a timepiece box, not visible, through a casing ring 2. The watch movement and the casing circle are only partially represented in transparency for the sake of clarity of the figures.
[0027] Une première partie 4 de tige de commande est partiellement logée à l'intérieur du mouvement horloger 1. La portion de cette tige située dans le mouvement horloger n'a pas été représentée pour simplifier les figures,
dans la mesure où elle est conventionnelle. De manière avantageuse, elle est en effet agencée pour coopérer avec une tirette (non illustrée) commandant elle-même les déplacements d'un pignon coulant (non illustré) solidaire en rotation de cette partie 4 de la tige. Ainsi, lorsque la première partie 4 de la tige est déplacée suivant sa direction longitudinale, d'une manière qui sera décrite plus loin, elle entraîne le pivotement de cette tirette qui provoque le déplacement du pignon coulant pour passer alternativement d'une configuration de remontage manuel à une configuration de mise à l'heure, et inversement, d'une manière bien connue de l'homme du métier. A first portion 4 of control rod is partially housed inside the watch movement 1. The portion of this rod located in the watch movement has not been shown to simplify the figures, as long as it is conventional. Advantageously, it is in fact arranged to cooperate with a pull (not shown) itself controlling the displacements of a sliding pinion (not shown) integral in rotation with this portion 4 of the rod. Thus, when the first portion 4 of the rod is moved in its longitudinal direction, in a manner that will be described later, it causes the pivoting of the puller which causes the displacement of the sliding pinion to pass alternately of a winding configuration manual to a time setting configuration, and vice versa, in a manner well known to those skilled in the art.
[0028] La portion 5 de la prem ière partie 4 de la tige de commande située à l'extérieur du mouvement horloger diffère sensiblement des structures connues de l'art antérieur. Celle-ci est disposée dans un évidement 6 ménagé dans le cercle d'encageage 2. The portion 5 of the first part 4 of the control rod located outside the watch movement differs substantially from the known structures of the prior art. This is arranged in a recess 6 formed in the casing ring 2.
[0029] En effet, cette portion 5 porte un premier pignon 8 agencé entre deux flasques 9, 10 en forme générale de disque, ici de même diamètre. Cet ensemble est maintenu fixé sur la portion 5 de la tige par le fait que le flasque 10 est serti à l'extrémité de la portion 5. Indeed, this portion 5 carries a first pinion 8 arranged between two flanges 9, 10 in the general form of disc, here of the same diameter. This assembly is held fixed on the portion 5 of the rod in that the flange 10 is crimped at the end of the portion 5.
[0030] De manière avantageuse, mais non limitative, le flasque 9 est ici réalisé d'une pièce avec la portion 5 de la première partie 4 de la tige. Advantageously, but not limited to, the flange 9 is here made in one piece with the portion 5 of the first portion 4 of the rod.
[0031 ] En alternative au sertissage du flasque 10 sur la portion 5, il est possible de prévoir qu'une vis est engagée axialement dans l'extrémité libre de la portion 5, pour assurer le maintien du flasque 10 et du pignon 8. As an alternative to crimping the flange 10 on the portion 5, it is possible to provide a screw is engaged axially in the free end of the portion 5, to maintain the flange 10 and the pinion 8.
[0032] On notera également que la portion 5 présente partiellement une section carrée (non visible) sur laquelle le pignon 8 est engagé, pour que ce dernier soit solidaire en rotation de la première partie de tige 4. It will also be noted that the portion 5 partially has a square section (not visible) on which the pinion 8 is engaged, so that the latter is integral in rotation with the first rod portion 4.
[0033] L'évidement 6 du cercle d'encageage 2 présente des dimensions telles que la première partie 4 de la tige peut être déplacée axialement entre au moins des première et seconde positions axiales. The recess 6 of the casing ring 2 has dimensions such that the first portion 4 of the rod can be moved axially between at least first and second axial positions.
[0034] La tige de commande comporte une seconde partie 1 2 de tige, d'axe décalé en référence à l'axe de la première partie 4 et représentée de manière schématique. On notera notamment que la portion de la pièce d'horlogerie visible sur le haut de la figure 1 correspond au côté cadran.
Ainsi, alors que la première partie 4 de la tige est disposée à proximité du fond de la boîte, du fait que le mouvement horloger de base mis en œuvre est surmonté d'un module additionnel disposé côté cadran, la seconde partie 12 est, elle, disposée sensiblement vers le milieu de la boîte. The control rod comprises a second portion 1 2 rod, axis offset with reference to the axis of the first portion 4 and shown schematically. Note in particular that the portion of the timepiece visible on the top of Figure 1 corresponds to the dial side. Thus, while the first part 4 of the rod is disposed near the bottom of the box, because the basic clockwork movement implemented is surmounted by an additional module disposed dial side, the second part 12 is, she , arranged substantially towards the middle of the box.
[0035] La seconde partie 12 de tige est destinée à porter une couronne de commande à l'extérieur de la boîte de la pièce d'horlogerie, notamment pour permettre à un utilisateur de remonter manuellement le mouvement horloger ou d'en effectuer une mise à l'heure, de manière conventionnelle. The second portion 12 of rod is intended to carry a control ring outside the timepiece of the watch, in particular to allow a user to manually remount the watch movement or to make a bet on time, in a conventional way.
[0036] Bien entendu, la mise en œuvre de ces caractéristiques reste possible en relation avec une tige destinée à commander d'autres fonctions de la pièce d'horlogerie, sans sortir du cadre de la présente invention. Of course, the implementation of these characteristics is possible in relation to a rod for controlling other functions of the timepiece, without departing from the scope of the present invention.
[0037] La seconde partie 12 de tige présente une surépaisseur annulaire 14 suivie, en direction de l'intérieur du mouvement horloger, d'une portion 15, de dimensions transversales inférieures à celles de la surépaisseur et de section carrée, la surépaisseur 14 définissant une surface de butée, par sa face interne, pour un second pignon 16. Le second pignon 16 porte un canon 17 et est agencé libre en translation sur la portion 15 de la seconde partie de tige 12, pour être solidaire en rotation de cette dernière. The second portion 12 of rod has an annular oversize 14 followed, in the direction of the interior of the watch movement, a portion 15 of transverse dimensions smaller than those of the extra thickness and square section, the overthickness 14 defining an abutment surface, by its internal face, for a second pinion 16. The second pinion 16 carries a gun 17 and is arranged free in translation on the portion 15 of the second rod portion 12, to be integral in rotation with the latter .
[0038] L'alésage (non visible) du pignon 16 et/ou de son canon 17 présente une section interne carrée pour coopérer avec le carré de la seconde partie 12 de tige. The bore (not visible) of the pinion 16 and / or its barrel 17 has a square internal section to cooperate with the square of the second portion 12 of the rod.
[0039] Le second pignon est disposé en prise avec le premier pignon 8 pour transmettre les mouvements de rotation de la seconde partie 12 de la tige à la première partie 4 de la tige. En outre, il apparaît clairement de la vue de la figure 2 que le second pignon est logé entre les flasques 9 et 10, de manière à coopérer avec eux pour transmettre les déplacements axiaux de la seconde partie 12 de la tige à la première partie 4 de la tige. The second pinion is arranged in engagement with the first pinion 8 to transmit the rotational movements of the second portion 12 of the rod to the first portion 4 of the rod. In addition, it is clear from the view of Figure 2 that the second pinion is housed between the flanges 9 and 10, so as to cooperate with them to transmit the axial displacement of the second portion 12 of the rod to the first part 4 of the stem.
[0040] Dans ce but, le second pignon 16 doit être asservi aux déplacements axiaux de la seconde partie 12 de la tige. Il ressort de son mode de coopération avec la seconde partie de tige 12 que la surface de butée définie par la surépaisseur 14 agit sur le second pignon pour le repousser en direction de l'intérieur du mouvement horloger lors des déplacements de la seconde partie de tige dans cette même direction.
[0041] Pour régler la question de l'asservissement du second pignon dans l'autre sens des déplacements de la seconde partie 12 de tige, il est prévu que le mécanisme de transmission selon la présente invention comporte une tirette 18 - additionnelle par rapport à la tirette conventionnelle déjà présente dans le mouvement horloger, comme mentionné plus haut - agencée de manière à coopérer à la fois avec la seconde partie 12 de tige et le second pignon 16. For this purpose, the second pinion 16 must be slaved to the axial displacements of the second portion 12 of the rod. It emerges from its mode of cooperation with the second rod portion 12 that the abutment surface defined by the excess thickness 14 acts on the second pinion to push it towards the inside of the watch movement during the movements of the second rod portion. in the same direction. To solve the question of the servocontrol of the second pinion in the other direction of the movements of the second portion 12 of rod, it is expected that the transmission mechanism according to the present invention comprises a pull 18 - additional to the the conventional zipper already present in the watch movement, as mentioned above - arranged to cooperate with both the second shaft portion 12 and the second pinion 16.
[0042] La tirette 18 est destinée à coopérer avec une gorge annulaire 19, ménagée dans la seconde partie de tige 12, de telle manière que la tirette pivote en réponse aux déplacements axiaux de la seconde partie de tige. The pull tab 18 is intended to cooperate with an annular groove 19 formed in the second rod portion 12, so that the pull rod pivots in response to the axial displacements of the second rod portion.
[0043] A cet effet, la tirette 18 comprend un doigt 20 disposé dans la gorge annulaire 19 et contre le second pignon 16, du côté du mouvement horloger, de manière à pouvoir repousser ce dernier en direction de l'extérieur lorsque la seconde partie 12 de tige est tirée. For this purpose, the pull tab 18 comprises a finger 20 disposed in the annular groove 19 and against the second pinion 16, on the watch movement side, so as to push the latter towards the outside when the second part 12 rod is drawn.
[0044] Il ressort de ce qui précède que lorsque la seconde partie 12 de la tige est poussée, depuis sa position la plus éloignée du mouvement horloger en direction de ce dernier, la surépaisseur annulaire 14 agit sur le second pignon 16, par l'intermédiaire de sa surface de butée, pour le repousser dans cette même direction. La tirette 18 suit le déplacement de la seconde partie de tige 12 en pivotant, du fait de la coopération de son doigt 20 avec la gorge annulaire 19. It follows from the above that when the second portion 12 of the rod is pushed from its position farthest from the watch movement towards the latter, the annular extra thickness 14 acts on the second pinion 16, by the intermediate its abutment surface, to push it in the same direction. The pull tab 18 follows the displacement of the second rod portion 12 by pivoting, because of the engagement of its finger 20 with the annular groove 19.
[0045] Le second pignon 16 agit alors sur le flasque 9 disposé côté mouvement pour le repousser en direction du mouvement, la première partie 4 de la tige suivant le même déplacement. The second pinion 16 then acts on the flange 9 disposed on the movement side to push it towards the movement, the first portion 4 of the rod following the same movement.
[0046] Ainsi, l'engrènement entre les premier et second pignons est ininterrompu lors des changements de positions axiales de la tige de commande. Thus, the meshing between the first and second pinions is uninterrupted during changes in axial positions of the control rod.
[0047] Lorsque la seconde partie de la tige est ramenée dans sa position tirée, par traction de la couronne de commande par un utilisateur, la tirette 18 pivote, du fait de la coopération entre son doigt 20 et la gorge annulaire 19, entraînant dans le même temps le second pignon. Le second pignon agit alors sur l'autre flasque 10 pour exercer une force de traction sur lui, donc sur la première partie 4 de la tige.
[0048] Cette opération est illustrée par le passage de la configuration du mécanisme de la figure 2a (position neutre ou de remontage de la tige) à celle de la figure 2b (position tirée de la tige, par exemple pour la mise à l'heure). When the second part of the rod is returned to its pulled position, by traction of the control ring by a user, the pull tab 18 pivots, because of the cooperation between its finger 20 and the annular groove 19, resulting in the same time the second gear. The second pinion then acts on the other flange 10 to exert a traction force on it, so on the first part 4 of the rod. This operation is illustrated by the passage of the configuration of the mechanism of Figure 2a (neutral position or winding of the rod) to that of Figure 2b (position drawn from the rod, for example for the setting to the hour).
[0049] Dans le même temps, le mécanisme de remontage et de mise à l'heure conventionnel, situé dans le mouvement horloger, remplit son rôle de manière connue. At the same time, the winding mechanism and conventional time setting, located in the watch movement, fulfills its role in a known manner.
[0050] On notera que le cercle d'encageage 2 comprend ici préférablement un alésage 22 dans lequel est engagée l'extrémité interne de la seconde partie de tige 12, dans le but d'assurer un guidage de cette dernière lors de ses déplacements. Note that the casing ring 2 here preferably comprises a bore 22 in which is engaged the inner end of the second rod portion 12, in order to provide guiding of the latter during its movements.
[0051 ] En ce qui concerne le mode d'assemblage de la tirette à un élément de bâti de la pièce d'horlogerie, il est similaire au mode de fixation habituellement mis en œuvre. As regards the method of assembling the zipper to a frame member of the timepiece, it is similar to the method of attachment usually implemented.
[0052] La tirette 18 comporte ici un trou 24 destiné à coopérer avec l'extrémité libre 25 d'une vis 26 de fixation, logée dans un trou adapté du cercle d'encageage 2. The pull tab 18 here comprises a hole 24 intended to cooperate with the free end 25 of a fixing screw 26, housed in a suitable hole of the casing ring 2.
[0053] L'extrémité de la tirette opposée au doigt 20 présente un bec 28 agencé pour coopérer avec l'extrémité libre 30 d'un ressort plat 31 dont la base 32 est également solidaire du cercle d'encageage, au moyen d'une vis (non représentée). L'extrémité libre 30 présente deux crans 33, 34, dont chacun est associé à l'une des positions axiales de la seconde partie 12 de tige en définissant les positions stables de la tirette 18. The end of the zipper opposite the finger 20 has a spout 28 arranged to cooperate with the free end 30 of a flat spring 31 whose base 32 is also integral with the casing ring, by means of a screw (not shown). The free end 30 has two notches 33, 34, each of which is associated with one of the axial positions of the second rod portion 12 by defining the stable positions of the pull tab 18.
[0054] Comme mentionné plus haut, il convient de relever que le procédé d'assemblage du mécanisme de transmission selon l'invention est nettement simplifié en référence aux procédés d'assemblage des mécanismes de l'art antérieur. En effet, la première partie 4 de tige ne doit être modifiée qu'à son extrémité externe, par rapport à une tige de commande conventionnelle, avant d'être mise en place dans le mouvement horloger et retenue par une tirette de base. Ensuite, le second pignon 16 peut être mis en place, en prise avec le premier pignon 8, puis la seconde partie 12 de la tige peut être insérée dans son logement, au travers de la boîte de la pièce d'horlogerie (le mouvement horloger ayant
été emboîté au préalable). La surépaisseur annulaire 14 définit alors une butée en coopération avec le second pignon, lors de la mise en place de la seconde partie de tige. La tirette 18 peut ensuite être assemblée au cercle d'encageage pour assurer le maintien de la seconde partie de tige et donc de l'ensemble. As mentioned above, it should be noted that the assembly method of the transmission mechanism according to the invention is clearly simplified with reference to assembly methods mechanisms of the prior art. Indeed, the first portion 4 rod must be modified at its outer end, relative to a conventional control rod, before being implemented in the watch movement and retained by a base pull. Then, the second pinion 16 can be put in place, in engagement with the first pinion 8, then the second portion 12 of the rod can be inserted into its housing, through the timepiece box (watch movement having been nested beforehand). The annular extra thickness 14 then defines a stop in cooperation with the second pinion, during the establishment of the second rod portion. The zipper 18 can then be assembled to the casing ring to maintain the second stem portion and thus the assembly.
[0055] Les figures 3a et 3b représentent respectivement des vues de face du mécanisme de transmission de la figure 1 , dans des première et seconde configurations respectives. Plus précisément, le mécanisme est représenté dans une vue suivant la direction axiale de la tige, depuis l'extérieur du mouvement horloger 1. Figures 3a and 3b respectively show front views of the transmission mechanism of Figure 1, in first and second respective configurations. More specifically, the mechanism is represented in a view along the axial direction of the rod, from outside the watch movement 1.
[0056] Une comparaison des figures 3a et 3b permet de mettre en évidence un avantage spécifique à la présente invention. A comparison of FIGS. 3a and 3b makes it possible to demonstrate a specific advantage to the present invention.
[0057] Il ressort en effet d'une telle comparaison que la seconde partie de tige 12 peut être agencée tout autour de l'axe de la première partie de tige 4, suivant un cercle dont le rayon correspond à l'entraxe X à prévoir entre les deux pignons 8 et 16. It is apparent from such a comparison that the second rod portion 12 can be arranged all around the axis of the first rod portion 4, in a circle whose radius corresponds to the distance X to be provided between the two gears 8 and 16.
[0058] Ainsi, il est possible, par exemple, de disposer la seconde partie de tige 12 exactement au milieu d'une boîte de montre, suivant son épaisseur, et ce, indépendamment de l'épaisseur d'un éventuel module d'affichage qui serait combiné à un mouvement horloger de base existant. Thus, it is possible, for example, to have the second portion of rod 12 exactly in the middle of a watch case, depending on its thickness, and regardless of the thickness of a possible display module. which would be combined with an existing basic watch movement.
[0059] Il suffit pour cela d'adapter la forme du cercle d'encageage pour pouvoir disposer la seconde partie de tige 12 à l'endroit souhaité, la simplicité d'assemblage étant inchangée quelle que soit la position de la tige. It is sufficient for this to adapt the shape of the casing circle to be able to have the second portion of rod 12 at the desired location, the simplicity of assembly being unchanged regardless of the position of the rod.
[0060] La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en œuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple les formes et dimensions relatives spécifiquement illustrées et décrites pour les différents ressorts et pignons. The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and, the invention is not limited to the implementation of certain particular features which have just been described, as for example the shapes and relative dimensions specifically illustrated and described for the different springs and sprockets.
[0061] L'homme du métier ne rencontrera pas de difficulté particulière pour adapter le contenu de la présente divulgation à ses propres besoins, et mettre en œuvre un mécanisme de transmission des mouvements entre les deux parties d'une tige d'axes décalés ne reprenant qu'en partie les
caractéristiques exposées ici, sans sortir du cadre de la présente invention. The skilled person will not encounter any particular difficulty in adapting the content of the present disclosure to his own needs, and implement a mechanism for transmitting movements between the two parts of a staggered axis rod. resuming that in part characteristics disclosed herein without departing from the scope of the present invention.
[0062] Il est par exemple possible de mettre en œuvre des variantes de réalisation différentes de celles décrites en relation avec les figures. It is for example possible to implement different embodiments of those described in relation to the figures.
[0063] Ainsi, on peut notamment prévoir que la tirette comporte un second doigt agencé pour coopérer avec le second pignon 16 du côté de l'extérieur, l'un ou l'autre des deux doigts de la tirette coopérant alors avec une gorge annulaire de la seconde partie de tige pour asservir le pivotement de la tirette aux déplacements axiaux de cette dernière. De manière alternative, on peut aussi prévoir que chacun des doigts coopère avec une gorge annulaire adaptée de la seconde partie 12 de la tige, en étant agencé en appui contre un côté du second pignon 16, la provision de la surépaisseur annulaire 14 sur la tige n'étant dans ce cas pas absolument nécessaire. Thus, it can be provided that the pull tab comprises a second finger arranged to cooperate with the second pinion 16 on the outside, one or the other of the two fingers of the puller cooperating with a ring groove the second rod portion to control the pivoting of the pull tab axial displacements thereof. Alternatively, it is also possible that each of the fingers cooperates with an annular groove adapted to the second portion 12 of the rod, being arranged in abutment against one side of the second pinion 16, the provision of the annular extra thickness on the rod not being in this case not absolutely necessary.
[0064] On notera que dans les cas où la seconde partie de tige ne comporte pas la surépaisseur annulaire 14, sa mise en place est approximative dans un premier temps, jusqu'à ce que la tirette soit assemblée pour assurer non seulement son maintien mais également son positionnement axial. Note that in cases where the second portion of rod does not have the annular extra thickness 14, its implementation is approximate at first, until the zipper is assembled to ensure not only its maintenance but also its axial positioning.
[0065] Par ailleurs, on notera que les premier et second pignons 8 et 16 ne sont pas nécessairement agencés en prise directe pour la mise en œuvre de la présente invention. Un ou plusieurs renvois intermédiaires peuvent être prévus. Furthermore, it will be noted that the first and second pinions 8 and 16 are not necessarily arranged in direct connection for the implementation of the present invention. One or more intermediate references may be provided.
[0066] En outre, le mécanisme de transmission selon la présente invention n'est pas limité à la mise en œuvre d'un organe de commande destiné à effectuer le remontage ou la mise à l'heure de la pièce d'horlogerie. D'autres commandes sont également possibles sans sortir du cadre de l'invention.
In addition, the transmission mechanism according to the present invention is not limited to the implementation of a control member for performing the reassembly or setting time of the timepiece. Other commands are also possible without departing from the scope of the invention.
