The present invention relates to a control device for a timepiece comprising a first and a second mechanism arranged to be driven manually via the same kinematic chain, the device comprising:
  • two mobiles kinematically connected respectively to the first and the second mechanism;
  • an external movable member arranged to actuate the kinematic chain;
  • a walker comprising a toothed mobile and a movable support on which the toothed mobile is rotatably mounted, the toothed moving part forming part of the kinematic chain;

L'invention concerne également une pièce d'horlogerie comportant un dispositif de mise à l'heure conforme à la définition ci-dessus.The invention also relates to a timepiece including a time setting device as defined above.

ART ANTERIEURPRIOR ART

On connait déjà des dispositifs de commande pour pièce d'horlogerie qui sont conformes à la définition donnée en préambule. Le document de brevet CH 511 notamment décrit un dispositif de mise à l'heure pour une montre dont le cadran porte deux tours d'heures, c'est-à-dire deux petits cadrans, respectivement disposés à 3 heures et à 9 heures, et qui ont chacun leurs aiguilles d'heures et minutes. Chacune de ces paires d'aiguilles peut être mise à l'heure indépendamment de l'autre paire.Already known control devices for a timepiece that comply with the definition given in the preamble. The patent document CH 511 in particular describes a time-setting device for a watch whose dial carries two hours, that is to say two small dials, respectively arranged at 3 o'clock and at 9 o'clock, and who each have their hour and minute hands. Each of these pairs of needles can be set independently of the other pair.

Selon le document susmentionné, le dispositif de mise à l'heure comporte un baladeur formé par un renvoi monté rotatif sur un support mobile constitué par une bascule. Le renvoi est agencé pour être relié cinématiquement à la tige par un pignon coulant de manière à ce que la tige entraîne le renvoi en rotation.According to the aforementioned document, the time setting device comprises a walker formed by a return rotatably mounted on a mobile support constituted by a rocker. The return is arranged to be kinematically connected to the rod by a sliding pinion so that the rod causes the return rotation.

Ce dispositif de mise à l'heure comprend en outre un sélecteur qui comporte un organe externe de commande comprenant une targette et un excentrique. La targette est montée pivotante sur le bâti par une première de ses extrémités, alors que sa deuxième extrémité dépasse de la carrure à l'extérieur de la montre. Le porteur de la montre peut ainsi se servir de cette dernière pour faire commuter manuellement l'organe de commande entre deux positions extrêmes prédéfinies. A l'intérieur de la carrure, la première extrémité de la targette est fixée rigidement à l'excentrique, et ce dernier est agencé de telle manière que son axe de rotation est confondu avec l'axe de pivotement de la targette.This time setting device further comprises a selector which comprises an external control member comprising a bolt and an eccentric. The bolt is pivotally mounted on the frame by a first end, while its second end protrudes from the middle outside the watch. The wearer of the watch can thus use the latter to manually switch the control member between two predefined extreme positions. Inside the case, the first end of the bolt is fixed rigidly to the eccentric, and the latter is arranged in such a way that its axis of rotation coincides with the axis of pivoting of the bolt.

La bascule qui porte le renvoi est encore munie d'un deuxième bras rappelé en permanence contre l'excentrique par un ressort. On comprendra donc que lorsque l'excentrique est actionné en rotation dans un sens ou dans l'autre au moyen de la targette, sa rotation provoque le pivotement de la bascule dans le sens correspondant. Le renvoi porté par la bascule est ainsi amené à coopérer sélectivement avec l'un ou l'autre de deux mobiles dentés respectivement en lien cinématique avec la première et la deuxième paire d'aiguilles.The rocker which carries the return is still provided with a second arm constantly recalled against the eccentric by a spring. It will therefore be understood that when the eccentric is actuated in rotation in one direction or the other by means of the bolt, its rotation causes the pivoting of the rocker in the corresponding direction. The return carried by the rocker is thus made to cooperate selectively with one or the other of two toothed mobiles respectively cinematically connected to the first and second pairs of needles.

En comparant la description qui précède avec la définition donnée en préambule, on remarquera que dans le dispositif qui vient d'être décrit, une seule et même bascule joue à la fois le rôle de levier de positionnement du sélecteur et celui de support mobile du baladeur. On comprendra toutefois, que le support mobile qui porte le mobile denté du baladeur et le levier de positionnement pourrait alternativement former deux pièces distinctes, ces deux pièces étant alors associées par un lieu mécanique.Comparing the foregoing description with the definition given in the preamble, it will be noted that in the device which has just been described, a single flip-flop plays both the role of positioning lever of the selector and that of the mobile support of the player . However, it will be understood that the mobile support which carries the toothed mobile of the walkman and the positioning lever could alternately form two separate parts, these two parts being then associated by a mechanical place.

Les dispositifs de mises à l'heure à verrou ou targette comme celui qui vient d'être décrit présentent certains défauts. En effet, lorsqu'on actionne l'organe de commande externe pour amener le renvoi du baladeur à venir engrener avec un autre mobile denté, il se peut que les sommets de certaines dents du renvoi butent contre des sommets de dents du mobile denté. Cette situation a pour effet de coincer le mécanisme, empêchant les deux dentures de s'interpénétrer et donc les mobiles d'engrener. De plus, dans une telle situation où la course du baladeur s'interrompt prématurément en cours de route, l'organe externe de commande va également se bloquer avant d'avoir atteint la position prédéfinie. Le porteur de la montre peut ressentir ce blocage, et il risque de casser un composant s'il essaye de forcer.The devices for setting the time to lock or bolt as the one just described have some defects. Indeed, when operating the external control member to cause the return of the player to come to mesh with another toothed mobile, it is possible that the tops of some teeth of the abutment abut against tooth tops of the toothed mobile. This situation has the effect of jamming the mechanism, preventing the two teeth from interpenetrating and thus the motive to mesh. In addition, in such a situation where the run of the player stops prematurely en route, the external control member will also block before reaching the predefined position. The wearer of the watch may feel this blockage, and he may break a component if he tries to force.

Le document de brevet US 330,273 propose de remédier au problème ci-dessus grâce à un mécanisme à tige de remontage et de mise à l'heure original (les lettres majuscules entre parenthèses qui figurent dans le texte ci-dessous font référence aux dessins du document de brevet susmentionné). Le mécanisme décrit dans ce document antérieur comporte un baladeur formé d'un support mobile (D) qui est monté pivotant coaxialement avec la roue de chant du remontoir et qui porte deux mobiles dentés (M et U). Ces derniers sont reliés en permanence à la tige de remontoir. Le mécanisme comporte encore un sélecteur comprenant un levier de commande (A) commutable manuellement entre deux positions prédéfinies, et comprenant également un ressort (B) en forme de Y dont la fourche (Z) est agencée pour venir en appui contre une goupille (G) tout en pouvant pivoter autour de cette goupille. Le levier de commande (A) présente un pied (E) qui est agencé pour s'insérer entre les branches de la fourche (Z) de manière à être en prise avec le ressort (B). L'autre extrémité de ce dernier est insérée dans une encoche ménagée dans un premier bras d'un levier oscillant (C) qui est lui-même agencé pour pivoter autour d'un axe (I). L'autre bras (J) du levier oscillant (C) est inséré dans une encoche (L) du support mobile (D) du baladeur.The patent document US 330,273 proposes to remedy the above problem by means of an original winding and setting rod mechanism (the capital letters in parentheses in the text below refer to the drawings of the aforementioned patent document). The mechanism described in this prior document comprises a walker formed of a movable support (D) which is pivotally mounted coaxially with the winding edge wheel and which carries two toothed mobiles (M and U). These are permanently connected to the winding stem. The mechanism further comprises a selector comprising a control lever (A) manually switchable between two predefined positions, and also comprising a Y-shaped spring (B) whose fork (Z) is arranged to bear against a pin (G). ) all in pivotable around this pin. The control lever (A) has a foot (E) which is arranged to fit between the branches of the fork (Z) so as to engage the spring (B). The other end of the latter is inserted into a notch in a first arm of an oscillating lever (C) which is itself arranged to pivot about an axis (I). The other arm (J) of the oscillating lever (C) is inserted in a notch (L) of the mobile support (D) of the player.

Le fonctionnement du mécanisme qui vient d'être décrit est le suivant. Lorsque le levier de commande (A) est repoussé, son pied (E) presse contre une première branche (F) de la fourche (Z) du ressort (B) en forme de Y. La pression du pied (E) force le ressort (B) à prendre une configuration flambée dans un premier sens. Dans cette configuration, l'autre extrémité du ressort (B) entraîne le levier oscillant (C) à pivoter dans le sens horaire, de sorte que le bras (J) du levier oscillant (C) vient appuyer contre un premier bord (K) de l'encoche (L) du baladeur. Ce dernier est ainsi entraîné en direction du rochet de remontoir (N) de sorte que les dents du rochet coopèrent avec celles du mobile denté (M).The operation of the mechanism just described is as follows. When the control lever (A) is pushed back, its foot (E) presses against a first branch (F) of the fork (Z) of the Y-shaped spring (B). The pressure of the foot (E) forces the spring (B) to take a flambé configuration in a first sense. In this configuration, the other end of the spring (B) causes the swing lever (C) to pivot clockwise, so that the arm (J) of the swing lever (C) is pressed against a first edge (K) of the notch (L) of the walkman. The latter is thus driven towards the winding ratchet (N) so that the teeth of the ratchet cooperate with those of the toothed wheel (M).

Lorsque le levier de commande (A) est tiré, son pied (E) presse contre la seconde branche (P) de la fourche (Z). La pression du pied (E) force le ressort (B) à passer à une configuration flambée dans l'autre sens. En changeant de configuration, le ressort (B) force le levier oscillant (C) à pivoter dans le sens antihoraire, de sorte que le baladeur est entraîné dans le sens horaire et que, soit les dents du mobile denté (U) viennent directement en prise avec celles du renvoi de mise à l'heure (V), soit elles butent contre le sommet des dentes du renvoi (V). Dans ce deuxième cas, le ressort (B) joue le rôle d'un ressort de rappel qui pousse le mobile denté (U) en direction du renvoi (V). Grâce à cette force de rappel, les dents du mobile denté (U) chutent entre celles du renvoi de mise à l'heure (V) dès que l'utilisateur a fait tourner un peu les dents du mobile (U) en actionnant la tige. Comme le mobile denté (U) est porté par le baladeur, ce dernier accompagne alors le mobile (U) en terminant sa course dans le sens horaire.When the control lever (A) is pulled, its foot (E) presses against the second leg (P) of the fork (Z). The pressure of the foot (E) forces the spring (B) to move to a flaming configuration in the other direction. By changing the configuration, the spring (B) forces the swing lever (C) to rotate counterclockwise, so that the player is driven clockwise and that either the teeth of the toothed gear (U) come directly into position. taken with those of the time setting back (V), or they abut against the top of the teeth of the return (V). In this second case, the spring (B) acts as a return spring which pushes the toothed moving (U) towards the return (V). Thanks to this restoring force, the teeth of the toothed gear (U) fall between those of the time setting wheel (V) as soon as the user has rotated the teeth of the wheel (U) a little by actuating the rod . As the toothed mobile (U) is carried by the player, it then accompanies the mobile (U) ending its race clockwise.

Un avantage du mécanisme à tige de remontage et de mise à l'heure qui vient d'être décrit est qu'il rend un éventuel blocage du baladeur invisible pour l'utilisateur. En effet, dans l'éventualité où la course du baladeur serait stoppée inopinément par une collision de certaines dents de l'un ou l'autre des deux mobiles dentés (M et U) contre la denture du rochet de remontoir (N) ou contre celle du renvoi de mise à l'heure (V), le ressort (B) serait en mesure de se déformer pour permettre au levier de commande (A) d'atteindre quand même sa position extrême.An advantage of the winding and setting mechanism that has just been described is that it makes a possible blocking of the walkman invisible to the user. Indeed, in the event that the race of the player would be stopped unexpectedly by a collision of some teeth of one or other of the two toothed mobiles (M and U) against the teeth of the ratchet winding (N) or against that of the setting back (V), the spring (B) would be able to deform to allow the control lever (A) to reach anyway its extreme position.

Il est important de noter, toutefois, que le recours à un bras flexible constitué par un ressort conformément à l'enseignement du document de brevet US 330,273 présente également quelques inconvénients. En effet, de manière connue en soi, lorsque le mobile denté du baladeur entraîne le mobile avec lequel il engrène en rotation, la résistance opposée par ce dernier va engendrer un couple résultant qui tend à faire pivoter le baladeur dans un sens ou dans l'autre selon le sens dans lequel on fait tourner la tige de commande. On comprendra que ce couple résultant ne pose pas de problème lorsqu'il s'exerce dans le sens tendant à rappeler le mobile denté contre la denture du mobile avec lequel il engrène. En revanche, lorsqu'il s'exerce dans l'autre sens avec suffisamment d'intensité, ce couple risque de provoquer une rupture d'engrènement entre le mobile denté et le mobile avec lequel il est en prise. En effet, le levier de positionnement du baladeur est commandé par l'intermédiaire du bras flexible constitué par un ressort. Dans ces conditions, le levier de positionnement risque de ne pas être tenu avec la rigidité nécessaire pour résister au couple susmentionné et donc pour retenir le baladeur en position d'engrènement.It is important to note, however, that the use of a flexible spring arm in accordance with the teaching of the patent document US 330,273 also has some disadvantages. Indeed, in a manner known per se, when the toothed mobile of the player drives the mobile with which it meshes in rotation, the resistance opposed by the latter will generate a resulting torque that tends to rotate the player in one direction or in the other according to the direction in which the control rod is rotated. It will be understood that this resulting torque does not pose a problem when it is exercised in the direction tending to return the toothed mobile against the toothing of the mobile with which it meshes. On the other hand, when it is exercised in the other direction with sufficient intensity, this couple risks to cause a break of meshing between the mobile toothed and the mobile with which it is in engagement. Indeed, the positioning lever of the player is controlled by means of the flexible arm constituted by a spring. Under these conditions, the positioning lever may not be held with the rigidity necessary to withstand the aforementioned torque and thus to retain the player in meshing position.

Dans le but de remédier à ce dernier problème, le document de brevet antérieur susmentionné enseigne que, lorsque le levier de commande (A) est tiré et que le baladeur a terminé sa course dans le sens horaire, les dents du mobile denté (U) ayant chuté entre celles du renvoi de mise à l'heure (V), le levier oscillant (C) achève sa propre course dans le sens antihoraire. A ce moment-là, le bord en arc de cercle concentrique de son extrémité (J) vient coopérer avec une portion arrondie concave du bord intérieur de l'encoche (L) du support mobile (D) du baladeur. Dans cette configuration, le support mobile (D) du baladeur est bloqué. La mise à l'heure peut ainsi être opérée indifféremment vers l'avant ou vers l'arrière, sans risque de provoquer le désengagement du mobile denté (U) d'avec le renvoi (V). Lorsque le levier de commande (A) se trouve au contraire en position repoussée, le baladeur est rappelé en direction du rochet de remontoir (N) de sorte que les dents du rochet sont amenées à coopérer avec celles du mobile denté (M). Comme le remontage du barillet se fait dans un seul sens, le problème susmentionné ne se pose pas quand le levier de commande (A) est en position repoussée. On comprendra de ce qui précède que le levier oscillant (C) joue non seulement le rôle de levier de positionnement agencé pour faire pivoter le baladeur, mais qu'il joue également le rôle de bloqueur agencé pour bloquer le support mobile (D) du baladeur dans sa position de mise à l'heure.In order to remedy this latter problem, the aforementioned prior patent document teaches that, when the control lever (A) is pulled and the player has completed its travel in the clockwise direction, the teeth of the toothed gear (U) having fallen between those of the time reference (V), the oscillating lever (C) completes its own stroke in the counterclockwise direction. At that moment, the edge concentric arc of its end (J) cooperates with a concave rounded portion of the inner edge of the notch (L) of the mobile support (D) of the player. In this configuration, the mobile support (D) of the player is blocked. The time setting can thus be operated indifferently forwards or backwards, without risk of causing disengagement of the toothed mobile (U) with the reference (V). When the control lever (A) is instead in the pushed position, the player is recalled towards the winding ratchet (N) so that the teeth of the ratchet are brought to cooperate with those of the toothed wheel (M). As the winding of the barrel is in one direction, the above problem does not arise when the control lever (A) is in the pushed position. It will be understood from the above that the oscillating lever (C) not only acts as a positioning lever arranged to rotate the player, but that it also acts as a blocker arranged to block the mobile support (D) of the player in its position of setting time.

Le levier oscillant (C) ne permettant de bloquer le baladeur que d'un seul côté, on comprendra que la solution de l'art antérieur qui vient d'être décrite ne donne pas satisfaction dans le cas où les deux mécanismes qui sont prévus pour être entraînés sélectivement par l'intermédiaire du baladeur doivent tous les deux pouvoir être actionnés dans les deux sens.Since the oscillating lever (C) makes it possible to block the walkman only on one side, it will be understood that the solution of the prior art which has just been described is unsatisfactory in the case where the two mechanisms which are provided for to be selectively driven via the player must both be actuable in both directions.

DESCRIPTION DETAILLEE D'UN MODE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT

La figure 1 annexée est une représentation schématique partielle en plan de certains éléments d'un dispositif de commande pour pièce d'horlogerie qui peut être conforme à un mode de réalisation particulier de l'invention. Le dispositif de commande représenté est prévu pour servir de mise à l'heure. Toutefois, dans le but de ne pas surcharger le dessin, on n'a pas représenté le premier et le deuxième mécanisme que le dispositif de commande est censé mettre à l'heure, et on comprendra d'ailleurs que le dispositif de commande illustré pourrait avoir d'autres applications que celle de la mise à l'heure. A l'instar des dispositifs de mise à l'heure classiques, le dispositif de commande représenté comporte une tige de remontoir 3 mobile axialement entre une position de remontage et une position de mise à l'heure. Il convient de noter toutefois que, selon une variante, la tige de remontoir pourrait, par exemple, être remplacée par un organe externe que ne serait mobile qu'en rotation, sans possibilité de le faire coulisser. L'un est l'autre de ces deux agencements sont connus de l'homme du métier, et ils ne seront pas décrits plus en détail.The figure 1 appended is a partial schematic representation in plan of certain elements of a control device for a timepiece which may be in accordance with a particular embodiment of the invention. The control device shown is intended to serve as a time setting. However, in order not to overload the drawing, it is not represented the first and the second mechanism that the control device is supposed to set on time, and it will be understood moreover that the illustrated control device could have other applications than that of setting the time. Like the conventional time setting devices, the control device shown comprises a winding stem 3 axially movable between a winding position and a setting time setting position. It should be noted, however, that, alternatively, the The winding stem could, for example, be replaced by an external member that would be mobile in rotation, without the possibility of sliding. One is the other of these two arrangements are known to those skilled in the art, and they will not be described in more detail.

Le dispositif représenté comprend encore un pignon de correction 5 qui est monté dans l'axe de la tige 3 de manière à tourner avec cette dernière lorsqu'elle est en position de mise à l'heure. Le pignon 5 est en prise avec un train d'engrenages formé, dans l'exemple illustré, de deux renvois 7 et 9 montés libres en rotation. Le dispositif représenté comporte encore un baladeur 12 constitué d'un support mobile 13 et d'un renvoi correcteur 15 qui est monté pivotant sur le support mobile. On peut observer que, dans l'exemple illustré, l'axe de rotation 10 du deuxième renvoi 9 est confondu avec l'axe de pivotement du support mobile du baladeur 12, et que le renvoi 15 du baladeur est agencé pour engrener en permanence avec le renvoi 9, de sorte que la tige 3 peut entraîner le renvoi correcteur 15 en rotation. On notera toutefois que, comme le sait l'homme du métier, l'axe du baladeur pourrait éventuellement ne pas être concentrique au renvoi 9. On peut voir encore que le renvoi 15 du baladeur est monté sur un axe de pivotement 14 qui est solidaire par une de ses extrémités du support 13. L'autre extrémité de l'axe 14 peut coulisser librement dans une fente 16 formant un arc de cercle concentrique à l'axe de pivotement du baladeur. La fente 16 est aménagée dans la platine (non représentée) ou dans un pont (non représenté).The device shown also comprises a correction pinion 5 which is mounted in the axis of the rod 3 so as to rotate with the latter when it is in the setting position. The pinion 5 is engaged with a gear train formed, in the illustrated example, two referrals 7 and 9 mounted free in rotation. The device shown also comprises a walkman 12 consisting of a movable support 13 and a corrector 15 which is pivotally mounted on the movable support. It can be observed that, in the example illustrated, the axis of rotation 10 of the second reference 9 coincides with the axis of pivoting of the mobile support of the player 12, and that the reference 15 of the player is arranged to mesh permanently with 9, so that the rod 3 can cause the corrective return 15 in rotation. Note however that, as known to those skilled in the art, the axis of the player could possibly not be concentric to the reference 9. It can be seen again that the reference 15 of the player is mounted on a pivot axis 14 which is secured by one of its ends of the support 13. The other end of the axis 14 can slide freely in a slot 16 forming a circular arc concentric with the pivot axis of the player. The slot 16 is arranged in the plate (not shown) or in a bridge (not shown).

Lorsque le baladeur 12 pivote autour de l'axe 10, l'extrémité libre de l'axe 14 l'accompagne en suivant la fente 16 dans le sens de la longueur. Ainsi, on comprendra que les deux extrémités (non référencées) de la fente 16 vont faire office de butées pour l'axe 14, et que la longueur de la fente 16 détermine la taille du secteur à l'intérieur duquel le baladeur 12 est libre de pivoter. C'est la raison pour laquelle, nous désignerons ci-après la première et la seconde extrémité de la fente 16 respectivement par les expressions de première et de seconde butée d'engrènement. Nous désignerons en outre les deux positions occupées par le baladeur 12 lorsque l'axe 14 bute respectivement contre la première et la seconde butée d'engrènement par les expressions de première et de deuxième position de correction. Comme on peut le voir dans la figure 1, lorsque le baladeur est dans la première position de correction, le renvoi 15 engrène avec un premier mobile 17, et réciproquement lorsque le baladeur est dans la seconde position de correction, le renvoi 15 engrène avec un second mobile 19. On comprendra en outre que le premier mobile 17 et le second mobile 19 sont respectivement en lien cinématique avec un premier et un deuxième mécanisme qui, dans le présent exemple, sont deux mécanismes d'affichage comportant chacun au moins un organe indicateur (non représenté).When the player 12 pivots about the axis 10, the free end of the shaft 14 accompanies it following the slot 16 in the lengthwise direction. Thus, it will be understood that the two ends (not referenced) of the slot 16 will act as stops for the axis 14, and that the length of the slot 16 determines the size of the sector within which the player 12 is free to rotate. This is the reason why we will hereinafter denote the first and the second end of the slot 16 respectively by the expressions of first and second meshing stop. We will also designate the two positions occupied by the walkman 12 when the axis 14 abuts respectively against the first and the second meshing stop by the expressions of first and second correction position. As can be seen in the figure 1 when the player is in the first correction position, the return 15 meshes with a first mobile 17, and vice versa when the player is in the second correction position, the return 15 meshes with a second mobile 19. It will further be understood that the first mobile 17 and the second mobile 19 are respectively kinematic link with a first and a second mechanism which, in the present example, are two display mechanisms each comprising at least one indicator member (not shown).

Conformément à l'invention, le dispositif de commande pour pièce d'horlogerie comprend encore un sélecteur prévu pour commander le baladeur 12 de manière à faire sélectivement engrener le renvoi correcteur 15 avec le premier ou le second mobile 17, 19. Conformément au présent mode de réalisation, le sélecteur comporte une targette 21 accessible depuis l'extérieur de la pièce d'horlogerie et qui est commutable manuellement entre deux positions prédéfinies. Le sélecteur comporte également un levier de positionnement 23 monté pivotant sur un axe 24. En se référant toujours à la figure 1, on peut voir que le levier 23 comporte un premier et un deuxième bras (référencés respectivement 25 et 27) qui s'étendent de part et d'autre de l'axe de pivotement. On peut voir également que l'extrémité distale du premier bras 25 est en prise avec la targette 21 de sorte que le levier de positionnement 23 est amené à basculer dans un sens ou dans l'autre en réaction aux commutations de la targette. Le deuxième bras (référencé 27) se termine par une fourche en U agencée pour recevoir et pour guider entre ses branches l'axe 14 du renvoi correcteur 15. La fourche en U et l'axe 14 forment ensemble une sorte d'articulation qui relie le levier de positionnement 23 et le baladeur 12. Grâce à la présence de ce lien articulé, le support mobile 13 du baladeur 12 est contraint d'accompagner en pivotant tout basculement du levier de positionnement 23. Ainsi, en actionnant la targette 21 du sélecteur, un utilisateur peut faire engrener le renvoi 15 du baladeur 12 sélectivement avec le premier mobile 17 ou avec le second mobile 19.According to the invention, the control device for a timepiece further comprises a selector provided for controlling the player 12 so as to selectively meshing the corrector 15 with the first or second mobile 17, 19. In accordance with the present mode embodiment, the selector comprises a bolt 21 accessible from outside the timepiece and which is manually switchable between two predefined positions. The selector also comprises a positioning lever 23 pivotally mounted on an axis 24. Referring always to the figure 1 it can be seen that the lever 23 comprises a first and a second arm (referenced respectively 25 and 27) which extend on either side of the pivot axis. It can also be seen that the distal end of the first arm 25 is engaged with the bolt 21 so that the positioning lever 23 is tilted in one direction or the other in response to switching of the bolt. The second arm (referenced 27) ends with a U-shaped fork arranged to receive and to guide between its branches the axis 14 of the corrector 15. The U-shaped fork and the axis 14 together form a kind of articulation which connects the positioning lever 23 and the player 12. Thanks to the presence of this articulated link, the mobile support 13 of the player 12 is forced to accompany by pivoting any tilting of the positioning lever 23. Thus, by actuating the bolt 21 of the selector , a User can mesh the reference 15 of the player 12 selectively with the first mobile 17 or with the second mobile 19.

Comme déjà mentionné, un risque existe que l'actionnement de la targette 21 échoue à faire engrener le renvoi correcteur 15 avec un des mobiles 17 et 19. En effet, il peut arriver que les sommets de certaines dents du renvoi 15 butent contre les sommets de dents du mobile 17 ou du mobile 19, de sorte que le baladeur 12 se trouve empêché de pivoter jusqu'à la première ou la deuxième position de correction. Conformément à l'invention, le premier bras 25 du levier 23 est capable de se déformer en flexion lorsqu'il est soumis à une contrainte. Ainsi, lorsque le baladeur 12 n'a pas pu atteindre sa position d'engrènement en raison du blocage susmentionné, Le bras 25 du levier de positionnement se déforme de façon à permettre à la targette 21 de basculer quand même jusqu'à sa position prédéfinie. Un avantage lié à la flexibilité du premier bras est donc que le blocage est invisible pour l'utilisateur. De plus, comme l'utilisateur ne s'aperçoit pas du blocage, il n'est pas tenté d'essayer de débloquer le mécanisme en forçant. Un autre avantage est donc de réduire les risques de casse.As already mentioned, there is a risk that the actuation of the bolt 21 fails to mesh the corrector 15 with a mobile 17 and 19. In fact, it may happen that the vertices of some teeth of the reference 15 abut against the vertices teeth of the mobile 17 or the mobile 19, so that the player 12 is prevented from pivoting to the first or second correction position. According to the invention, the first arm 25 of the lever 23 is able to deform in bending when subjected to stress. Thus, when the player 12 could not reach its meshing position because of the aforementioned blocking, the arm 25 of the positioning lever is deformed so as to allow the bolt 21 to switch anyway to its predefined position . An advantage related to the flexibility of the first arm is therefore that the blocking is invisible to the user. Moreover, as the user does not notice the blocking, he is not tempted to try to unlock the mechanism by forcing. Another advantage is therefore to reduce the risk of breakage.

Comme le premier bras 25 du levier de positionnement est élastique, il se comporte comme un ressort de rappel lorsqu'il est déformé. Tant que le baladeur 12 n'a pas réussi à atteindre sa position d'engrènement, il est soumis à une force élastique qui le pousse à terminer sa course. Ainsi, lorsque l'utilisateur actionne la tige de remontoir, de manière à décaler les dents du mobile 15 par rapport à celles du mobile 17 ou à celles du mobile 19, le baladeur est poussé jusqu'à sa position d'engrènement sous l'effet de la force de ressort du bras flexible 25. Le système se remet ainsi en place de lui-même.Since the first arm 25 of the positioning lever is resilient, it behaves as a return spring when it is deformed. As long as the player 12 has not managed to reach its meshing position, it is subjected to an elastic force that pushes him to finish his race. Thus, when the user actuates the winding stem, so as to shift the teeth of the mobile 15 relative to those of the mobile 17 or those of the mobile 19, the player is pushed to its meshing position under the effect of the spring force of the flexible arm 25. The system thus resets itself.

Les figures 2A et 2B annexées sont deux représentations schématiques en plan d'un même dispositif de commande pour pièce d'horlogerie, qui est conforme à un mode de réalisation particulier de l'invention. A cet égard, on notera que ce mode de réalisation particulier de l'invention possède toutes les caractéristiques déjà représentées dans la figure 1. Les éléments du dispositif de commande des figures 2A et 2B qui figurent déjà dans la figure 1 sont désignés par les mêmes numéros de référence.The Figures 2A and 2B appended are two schematic representations in plan of the same control device for a timepiece, which is in accordance with a particular embodiment of the invention. In this respect, it should be noted that this particular embodiment of the invention has all the features already represented in the figure 1 . The elements of the command of Figures 2A and 2B already in the figure 1 are designated by the same reference numbers.

Les figures 2A et 2B montrent deux bascules qui ne sont pas représentées dans la figure 1. Ces deux bascules sont d'une part un bloqueur 31 qui est pivoté sur un axe 33, et d'autre part, une bascule inter 35 qui est pivotée sur un axe 37. Comme on peut le voir, le bloqueur 31 comporte deux bras qui s'étendent radialement depuis l'axe de pivotement 33. Un des deux bras et un bras de commande 39 dont l'extrémité distale est agencée pour coopérer avec la bascule inter 35, et l'autre bras est un bras de blocage 41 dont l'extrémité distale est agencée pour coopérer avec le levier de positionnement 23.The Figures 2A and 2B show two flip-flops that are not represented in the figure 1 . These two flip-flops are on the one hand a blocker 31 which is pivoted on an axis 33, and on the other hand, an inter flip-flop 35 which is pivoted on an axis 37. As can be seen, the blocker 31 comprises two arms which extend radially from the pivot axis 33. One of the two arms and a control arm 39 whose distal end is arranged to cooperate with the inter flip-flop 35, and the other arm is a locking arm 41 whose distal end is arranged to cooperate with the positioning lever 23.

Les figures 2B et 2A représentent respectivement le baladeur 12 dans la première de correction dans laquelle il coopère avec le mobile 17 et dans la deuxième position de correction dans laquelle il coopère avec le mobile 19. Maintenant, en se référant plus particulièrement à la figure 2A, on peut voir que dans la configuration illustrée le renvoi correcteur 15 du baladeur est bien en prise avec le mobile 19. On a vu que, dans cette configuration, l'extrémité libre de l'axe 14 est arrêtée contre la seconde butée d'engrènement (non représentée).The Figures 2B and 2A respectively represent the player 12 in the first correction in which it cooperates with the mobile 17 and in the second correction position in which it cooperates with the mobile 19. Now, referring more particularly to the Figure 2A , it can be seen that in the illustrated configuration the corrector 15 of the player is in engagement with the mobile 19. It has been seen that, in this configuration, the free end of the axis 14 is stopped against the second stop of meshing (not shown).

Conformément au mode de réalisation qui fait l'objet de la présente description, le dispositif de commande comporte des moyens de butée qui sont constitués par deux éléments d'arrêt complémentaires agencés pour coopérer de façon à retenir le baladeur 12 dans la deuxième position de correction. En se référant toujours à la figure 2A, on comprendra que les deux éléments d'arrêt sont constitués respectivement par un appendice 43 que présente la bascule de positionnement 23 et par l'extrémité distale du bras de blocage 41 du bloqueur 31. On peut voir que les deux arrêts sont positionnés directement en regard l'un de l'autre, de sorte que le levier de positionnement 23 est dans l'impossibilité de pivoter dans le sens horaire, et que le baladeur 12 est donc immobilisé dans la deuxième position de correction.According to the embodiment which is the subject of this description, the control device comprises stop means which consist of two complementary stop elements arranged to cooperate so as to hold the player 12 in the second correction position. . Referring always to the Figure 2A it will be understood that the two arresting elements consist respectively of an appendage 43 that the positioning lever 23 and the distal end of the locking arm 41 of the blocker 31 present. It can be seen that the two stops are positioned directly in position. facing each other, so that the positioning lever 23 is unable to rotate in the clockwise direction, and the player 12 is thus immobilized in the second correction position.

La présence du bloqueur 31 permet de remédier à un inconvénient des dispositifs de commande de l'art antérieur. En effet, lorsque le renvoi 9 entraîne le renvoi correcteur 15 et le mobile 19 en rotation, la résistance opposée par ces deux mobiles engendre un couple résultant qui tend à faire pivoter le baladeur dans un sens ou dans l'autre selon le sens dans lequel on fait tourner le renvoi 9 à l'aide de la tige de commande 3. En se référant toujours à la figure 2A, on peut comprendre que ce couple résultant ne pose pas de problème lorsque le renvoi 9 tourne dans le sens antihoraire. En revanche, lorsque le renvoi 9 tourne dans le sens horaire, le couple résultant tend à faire pivoter le baladeur 12 dans le même sens, l'écartant du mobile 19. En l'absence d'un bloqueur, le baladeur risque de quitter la deuxième position de correction en faisant fléchir le bras élastique 25 du levier de positionnement. La présence du bloqueur 31 et des moyens de butée permet de parer à cette éventualité.The presence of the blocker 31 overcomes a disadvantage of the control devices of the prior art. Indeed, when the reference 9 causes the corrective return 15 and the mobile 19 in rotation, the resistance opposed by these two mobiles generates a resulting torque that tends to rotate the player in one direction or the other depending on the direction in which the reference 9 is rotated by means of the control rod 3. Referring always to the Figure 2A it can be understood that this resultant torque does not pose a problem when the return 9 rotates counterclockwise. However, when the reference 9 rotates clockwise, the resulting torque tends to rotate the player 12 in the same direction, away from the mobile 19. In the absence of a blocker, the player may leave the second correction position by bending the elastic arm 25 of the positioning lever. The presence of the blocker 31 and the stop means makes it possible to counter this eventuality.

En se référant maintenant à la figure 2B, on peut voir que le baladeur 12 est dans la première position de correction, le renvoi correcteur 15 du baladeur étant montré en prise avec le mobile 17. Dans cette configuration, l'extrémité libre de l'axe 14 du renvoi correcteur est arrêtée contre la première butée d'engrènement (non représentée). On notera de plus que, les éléments d'arrêt 41 et 43 sont positionnés à distance l'un de l'autre de sorte qu'ils ne coopèrent pas. Conformément au mode de réalisation qui fait l'objet de la présente description, le dispositif de commande comporte encore des moyens d'accrochage comprenant deux crochets complémentaires agencés pour coopérer de façon à retenir le baladeur 12 dans la première position de correction. En se référant maintenant à la figure 2B, on comprendra que les deux crochets sont constitués respectivement par une corne 45 disposée à la base du deuxième bras 27 de la bascule de positionnement 23 et par un crochet 47 que présente l'extrémité du bras de blocage 41 du bloqueur 31. La figure 2B illustre les deux crochets 45, 47 accrochés l'un à l'autre de sorte que le bras de blocage 41 retient le levier de positionnement 23, l'empêchant de pivoter dans le sens antihoraire, et que le baladeur est donc immobilisé dans la première position de correction. On notera en outre qu'un avantage du dispositif représenté dans les figures 2A et 2B est qu'il ne nécessite pas de prévoir un ressort de rappel pour le bloqueur 31. En se référant à nouveau à la figure 2A, on notera encore que, dans la configuration représentée, les crochets 45 et 47 sont positionnés à distance l'un de l'autre de sorte qu'ils ne coopèrent pas.Referring now to the Figure 2B , it can be seen that the player 12 is in the first correction position, the correction reference 15 of the player being shown in engagement with the mobile 17. In this configuration, the free end of the axis 14 of the correction is stopped against the first meshing stop (not shown). Note further that, the stop elements 41 and 43 are positioned at a distance from one another so that they do not cooperate. According to the embodiment which is the subject of the present description, the control device also comprises hooking means comprising two complementary hooks arranged to cooperate to hold the player 12 in the first correction position. Referring now to the Figure 2B it will be understood that the two hooks are constituted respectively by a horn 45 disposed at the base of the second arm 27 of the positioning lever 23 and by a hook 47 that has the end of the locking arm 41 of the blocker 31. Figure 2B illustrates the two hooks 45, 47 hooked to each other so that the locking arm 41 retains the positioning lever 23, preventing it from rotating counterclockwise, and that the The player is thus immobilized in the first correction position. In addition, it should be noted that an advantage of the device represented in the Figures 2A and 2B is that it does not need to provide a return spring for the blocker 31. Referring again to the Figure 2A it will also be noted that in the configuration shown, the hooks 45 and 47 are positioned at a distance from one another so that they do not cooperate.

Conformément au mode de réalisation du présent exemple, la bascule de positionnement 23 et le bloqueur 31 sont tous les deux actionnés par l'intermédiaire de la bascule inter 35. La figure 3 est une vue schématique en plan du dispositif de commande des figures 2A et 2B, le dispositif de commande étant représenté avec le baladeur 12 dans la première position d'engrènement, comme c'est déjà le cas dans la figure 2B.In accordance with the embodiment of the present example, the positioning rocker 23 and the blocker 31 are both actuated via the inter-35 flip-flop. figure 3 is a schematic plan view of the control device of the Figures 2A and 2B , the control device being shown with the player 12 in the first meshing position, as is already the case in the Figure 2B .

Comme le montre la figure 3, l'extrémité distale du bras 25 du levier de positionnement 23 coopère avec la bascule inter 35. A cet effet, la bascule inter comporte un premier guide 51 à l'intérieur duquel peut coulisser une goupille 49 fixée sur l'extrémité du bras 25. On peut observer que le guide 51 est sensiblement rectiligne. La bascule inter comporte encore un deuxième guide 55 à l'intérieur duquel peut coulisser une goupille 53 fixée sur l'extrémité du bras de commande 39 du bloqueur 31. Dans les figures 2A, 2B et 3, le guide 55 a une forme qui s'approche de celle d'un Z à l'envers. On notera toutefois que les formes des guides 51 et 55 dépendent des courses, des bras de levier et des vitesses de déplacement souhaitées. Ces formes peuvent donc varier considérablement d'un mode de réalisation à un autre.As shown in figure 3 , the distal end of the arm 25 of the positioning lever 23 cooperates with the inter-35 rocker. For this purpose, the inter rocker comprises a first guide 51 inside which can slide a pin 49 fixed on the end of the arm 25 It can be seen that the guide 51 is substantially rectilinear. The inter rocker further comprises a second guide 55 inside which can slide a pin 53 fixed on the end of the control arm 39 of the blocker 31. In the Figures 2A, 2B and 3 , the guide 55 has a shape that approaches that of a Z upside down. Note, however, that the shapes of the guides 51 and 55 depend on the strokes, the lever arms and the desired movement speeds. These shapes can therefore vary considerably from one embodiment to another.

Comme déjà mentionné, la bascule inter 35 est agencée pour pivoter autour d'un axe 37. Le fonctionnement du mécanisme d'actionnement de la bascule de positionnement 23 et du bloqueur 31 par la bascule inter 35 est le suivant. Lorsque le dispositif de commande est dans la configuration illustrée dans les figures 2B et 3, la goupille 53 du bras de commande 39 du bloqueur 31 se trouve dans la base du Z que dessine le deuxième guide 55. La base du Z est sensiblement parallèle au guide 51 qui commande la bascule de positionnement 23. Lorsqu'un utilisateur actionne l'organe externe de commande 57, il amène la bascule inter 35 à pivoter dans le sens horaire. L'orientation du guide 51 et de la base du Z du guide 55 est telle que les goupilles 49 et 53 sont soumises toutes les deux une force orientée sensiblement vers le bas de la figure. La force exercée sur la goupille 53 a pour effet de faire pivoter le bloqueur dans le sens horaire. En pivotant ainsi, le bloqueur provoque la séparation du crochet 47 d'avec la corne 45. Simultanément, la force exercée sur la goupille 49 a pour effet de faire pivoter le levier de positionnement 23 dans le sens antihoraire.As already mentioned, the inter rocker 35 is arranged to pivot about an axis 37. The operation of the actuating mechanism of the positioning rocker 23 and the blocker 31 by the inter rocker 35 is as follows. When the controller is in the configuration illustrated in the Figures 2B and 3 , the pin 53 of the control arm 39 of the blocker 31 is in the base of the Z that draws the second guide 55. The base of the Z is substantially parallel to the guide 51 which controls the positioning lever 23. When a user actuates the external control member 57, it causes the inter rocker to rotate in a clockwise direction. The orientation of the guide 51 and the Z base of the guide 55 is such that the pins 49 and 53 are both subjected to a substantially downwardly directed force of the figure. The force exerted on the pin 53 has the effect of rotating the blocker clockwise. By pivoting thus, the blocker causes the hook 47 to separate from the horn 45. Simultaneously, the force exerted on the pin 49 has the effect of pivoting the positioning lever 23 counterclockwise.

Comme déjà expliqué en relation avec le premier mode de réalisation, lorsque le levier de positionnement pivote dans le sens antihoraire, il fait pivoter le baladeur 12 dans même sens, de sorte que le renvoi correcteur 15 s'écarte du mobile 17 et se décale pour aller engrener avec le mobile 19. Simultanément, après avoir provoqué la séparation du crochet 47 d'avec la corne 45, la goupille 53 quitte la base du Z pour traverser sa partie diagonale et atteindre son sommet. Lorsque la goupille 53 atteint le sommet du Z, elle est à nouveau soumise à une force orientée sensiblement vers le bas de la figure. Cette force a pour effet de faire pivoter encore le bloqueur 31 dans le sens horaire, de sorte que le dispositif de mise à l'heure se trouve finalement dans la configuration de la figure 2A.As already explained in connection with the first embodiment, when the positioning lever pivots counterclockwise, it rotates the player 12 in the same direction, so that the corrector 15 deviates from the mobile 17 and shifts to Go to mesh with the mobile 19. Simultaneously, after having caused the hook 47 to separate from the horn 45, the pin 53 leaves the base of the Z to cross its diagonal portion and reach its summit. When the pin 53 reaches the top of the Z, it is again subjected to a force oriented substantially downwardly in the figure. This force has the effect of further turning the blocker 31 clockwise, so that the time setting device is finally in the configuration of the Figure 2A .

On comprendra en outre que diverses modifications et/ou améliorations évidentes pour un homme du métier peuvent être apportées au mode de réalisation qui fait l'objet de la présente description sans sortir du cadre de la présente invention définie par les revendications annexées.It will be further understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment which is the subject of the present description without departing from the scope of the present invention defined by the appended claims.
