Un tel mécanisme de positionnement est par exemple décrit dans la demande
Toutefois, ce mécanisme ne permet pas de réglage fin du levier de positionnement, souvent exigé dans le domaine de l'horlogerie. En particulier, un tel mécanisme ne permet pas de garantir un positionnement initial ou un repositionnement correct d'une denture destinée à coopérer avec une autre denture par périodes. De ce fait, les risques de défauts d'engrènement au démarrage ou au redémarrage de la roue dentée après un arrêt momentané sont importants.However, this mechanism does not allow fine adjustment of the positioning lever, often required in the field of watchmaking. In particular, such a mechanism does not guarantee initial positioning or correct repositioning of a toothing intended to cooperate with other teeth by periods. As a result, there is a significant risk of meshing faults when starting or restarting the gear wheel after a temporary stop.
L'invention a notamment pour objectif de pallier les inconvénients du mécanisme connu.The invention particularly aims to overcome the disadvantages of the known mechanism.
Plus précisément, un objectif de l'invention est de fournir un mécanisme de positionnement d'une roue dentée destinée à coopérer avec une autre roue dentée par périodes, ledit mécanisme de positionnement permettant un réglage fin du levier de positionnement afin de garantir un positionnement initial correct de la roue dentée ou son repositionnement, pour assurer un engrènement sans défaut entre lesdites roues dentées, en particulier après un arrêt momentané de la roue dentée.More specifically, an object of the invention is to provide a mechanism for positioning a gearwheel intended to cooperate with another gearwheel periodwise, said positioning mechanism for fine adjustment of the positioning lever to ensure initial positioning correct gear or repositioning, to ensure meshing without defects between said gears, particularly after a momentary stop of the toothed wheel.
A cet effet, la présente invention concerne un mécanisme de positionnement d'une roue dentée montée sur un axe mobile en rotation dans un mouvement horloger, ledit mécanisme de positionnement comprenant un levier de positionnement présentant un bord latéral plat agencé pour coopérer avec au moins un plat prévu sur l'axe de la roue dentée.To this end, the present invention relates to a mechanism for positioning a toothed wheel mounted on an axis movable in rotation in a watch movement, said positioning mechanism comprising a positioning lever having a flat lateral edge arranged to cooperate with at least one flat provided on the axis of the toothed wheel.
Selon l'invention, le levier de positionnement comprend un bras de pivotement agencé pour être monté pivotant autour d'un axe de pivotement prévu dans le mouvement horloger, un élément de positionnement présentant le bord latéral plat et monté articulé sur le bras de pivotement, et des moyens de réglage et de verrouillage de la position de l'élément de positionnement sur le bras de pivotement par rapport à l'axe de la roue dentéeAccording to the invention, the positioning lever comprises a pivoting arm arranged to be pivotally mounted about a pivot axis provided in the watch movement, a positioning element having the flat lateral edge and articulated on the pivoting arm, and means for adjusting and locking the position of the positioning element on the pivot arm relative to the axis of the gear wheel

En référence aux
Afin de garantir un positionnement correct de la roue dentée 1 après son arrêt, il est prévu un levier de positionnement 3 présentant un bord latéral plat 4 agencé pour coopérer avec un plat 6 prévu sur l'axe 2 de la roue dentée 4. Le plat 6 est réalisé sur l'axe 2 de manière à se positionner en regard du bord latéral 4 du levier de positionnement 3 lorsque la roue dentée 1 s'arrête après avoir pivoté de l'angle déterminé.In order to ensure correct positioning of the
Selon l'invention, le levier de positionnement 3 comprend un bras de pivotement 8 agencé pour être monté pivotant autour d'un axe de pivotement 10 prévu dans le mouvement horloger. A cet effet, le bras de pivotement présente, à une extrémité, une bague 12 montée pivotante sur l'axe de pivotement 10. A son autre extrémité, soit son extrémité libre, le bras de pivotement 8 porte un élément de positionnement 14 qui présente le bord latéral plat 4. Plus précisément, l'élément de positionnement 14 est monté superposé sur le bras de pivotement 8 de manière à présenter une extrémité extérieure 14a présentant le bord latéral plat 4 en regard de l'axe 2 de la roue dentée 1 et une extrémité intérieure 14b en regard de l'axe de pivotement 10 du bras de pivotement 8. L'élément de positionnement 14 est monté articulé sur le bras de pivotement 8 par son extrémité extérieure 14a au moyen d'un pivot 16 prévu à l'extrémité libre du bras de pivotement 8 et monté traversant dans l'extrémité extérieure 14a de l'élément de positionnement 14.According to the invention, the
En référence plus spécifiquement aux
Avantageusement, les moyens de réglage de la position de l'élément de positionnement 14 sur le bras de pivotement 8 par rapport à l'axe 2 de la roue dentée 1 comprennent un excentrique 22 monté sur le bras de pivotement 8 et agencé pour coopérer avec l'élément de positionnement 14. Plus particulièrement, l'excentrique 22 est monté sur le bras de pivotement 8 en se logeant dans la première ouverture oblongue 18 de manière à pouvoir coopérer avec les bords de ladite ouverture oblongue 18 pour faire pivoter l'élément de positionnement 14 autour du pivot 16 lors du réglage.Advantageously, the means for adjusting the position of the
De préférence, les moyens de verrouillage de la position de l'élément de positionnement 14 sur le bras de pivotement 8 par rapport à l'axe 2 de la roue dentée 1 comprennent une vis de serrage 24 montée sur le bras de pivotement 8 et agencée pour bloquer l'élément de positionnement 14 sur ledit bras de pivotement 8. Plus particulièrement, la vis de serrage 24 est montée sur le bras de pivotement 8 au travers de la seconde ouverture oblongue 20 de l'élément de positionnement 14. Ainsi, l'élément de positionnement 14 peut évoluer autour de la vis de serrage 24 lorsqu'il est pivoté pour le réglage.Preferably, the means for locking the position of the
Il est également prévu un ressort de maintien 26 du bras de pivotement. Comme le montre la
Le fonctionnement du mécanisme de positionnement selon l'invention est le suivant: au moment du montage du mécanisme, l'élément de positionnement 14 est positionné de sorte que son bord latéral plat 4 soit aligné avec le plat 6 prévu sur l'axe 2 de la roue dentée 1 qui se présente en regard de l'élément de positionnement 14 lorsque la roue dentée 1 est dans une position correspondant à sa position arrêtée après avoir pivoté de l'angle déterminé. L'élément de positionnement 14 appuie sur le plat 6 afin de repositionner correctement la roue dentée 1 pour que sa denture puisse engrener sans défaut avec le mécanisme associé au prochain redémarrage de la roue dentée 1.The operation of the positioning mechanism according to the invention is as follows: at the time of mounting the mechanism, the
Pour que l'effet du levier de positionnement 3 sur le plat 6 soit le plus efficace possible, il est nécessaire que le bord latéral plat 4 soit parfaitement aligné avec le plat 6. La position du levier de positionnement 3 doit donc être très finement réglée. A cet effet, l'élément de positionnement 14 est pivoté autour du pivot 16 au moyen de l'excentrique 22 coopérant avec les bords de la première ouverture oblongue 18 de manière à modifier plus ou moins la position angulaire a de l'élément de positionnement 14 par rapport au bras de positionnement 8, tel que représenté sur les
