Description
La présente invention se rapporte au domaine de l'horlogerie. Elle concerne, plus particulièrement, un mécanisme indicateur de réserve de marche d'une pièce d'horlogerie.The present invention relates to the field of watchmaking. It relates, more particularly, a mechanism indicating a power reserve of a timepiece.
Les documents
De tels mécanismes indicateurs de réserve de marche conviennent aux barillets les plus communs de nos jours, c'est-à-dire à des barillets remontés par leur arbre, qui actionnent le mouvement d'horlogerie par une denture disposée à la périphérie de leur tambour. Dans de tels barillets, l'arbre de barillet et le tambour tournent chacun dans des sens de rotation opposés.Such power reserve indicator mechanisms are suitable for the most common cylinders of today, that is to say, barrels raised by their shaft, which actuate the clockwork movement by a set of teeth arranged on the periphery of their drum. . In such barrels, the barrel shaft and the drum each rotate in opposite directions of rotation.
Cependant, de tels mécanismes indicateurs de réserve de marche ne conviennent pas aux barillets associés à des mécanismes de fusée, dans lesquels le barillet est remonté via la fusée. Dans de tels mécanismes, le tambour doit ainsi pouvoir tourner dans les deux sens de rotation. En outre, les mécanismes de réserve de marche de l'art antérieur sont peu appropriés pour être agencés de manière dite « volante » dans une montre squelette.However, such power reserve indicator mechanisms are not suitable for barrels associated with rocket mechanisms, in which the barrel is raised via the rocket. In such mechanisms, the drum must be able to rotate in both directions of rotation. In addition, the power reserve mechanisms of the prior art are not appropriate to be arranged so-called "flying" in a skeleton watch.
Le but de la présente invention est par conséquent d'atténuer au moins partiellement les limitations de l'art antérieur énoncées ci-dessus.The object of the present invention is therefore to at least partially mitigate the limitations of the prior art set forth above.
De façon plus précise, l'invention concerne un mécanisme indicateur de réserve de marche pour pièce d'horlogerie, qui comprend :
- un axe fileté destiné à être monté solidaire à un élément de bâti de ladite pièce d'horlogerie ;
- une came présentant une surface extérieure inclinée par rapport audit axe, la came étant agencée pour coopérer par vissage avec l'axe fileté ;
- un mobile entraîneur de ladite came, ledit mobile entraîneur étant destiné à être mis en rotation dans les deux sens de rotation au moyen d'un barillet de ladite pièce d'horlogerie, et comprenant au moins un moyen d'entraînement en rotation de ladite came, solidaire avec ledit mobile entraîneur ;
- un palpeur en contact avec ladite surface extérieure de la came et en liaison cinématique avec un indicateur de réserve de marche.
- a threaded shaft intended to be mounted integral with a frame member of said timepiece;
- a cam having an outer surface inclined with respect to said axis, the cam being arranged to cooperate by screwing with the threaded shaft;
- a driving mobile of said cam, said driving mobile being intended to be rotated in both directions of rotation by means of a cylinder of said timepiece, and comprising at least one means for driving said cam in rotation; , integral with said driving mobile;
- a feeler in contact with said outer surface of the cam and in kinematic connection with a power reserve indicator.
Grâce à ces caractéristiques est proposé un mécanisme indicateur de réserve de marche qui convient aux barillets associés à un mécanisme de fusée. De plus, à cause du fait que l'axe fileté est monté fixe à un élément de bâti de la pièce d'horlogerie, ce qui entraîne une stabilité mécanique importante, le mécanisme peut aisément être configuré de manière « volante », car l'axe fileté peut être supporté soit exclusivement à une seule extrémité, soit fermement à une extrémité et légèrement à l'autre extrémité.Thanks to these characteristics is proposed a power reserve indicator mechanism which is suitable for barrels associated with a rocket mechanism. In addition, because the threaded shaft is fixedly mounted to a frame member of the timepiece, resulting in significant mechanical stability, the mechanism can easily be configured "flying" because the Threaded shaft can be supported either exclusively at one end, or firmly at one end and slightly at the other end.
Dans un mode de réalisation particulier, au moins un moyen d'entraînement comprend au moins un tenon solidaire au mobile entraîneur. Ledit au moins un tenon est agencé substantiellement parallèle à l'axe fileté et passe à travers une ouverture correspondante ménagée dans ladite came, ce qui entraîne la came en rotation de manière simple et fiable, et sert en outre pour son guidage.In a particular embodiment, at least one drive means comprises at least one integral tenon to the driving mobile. Said at least one tenon is arranged substantially parallel to the threaded axis and passes through a corresponding opening in said cam, which drives the cam in rotation simply and reliably, and is further used for its guidance.
Dans encore un autre mode de réalisation particulier, la came est de forme tronconique. Une telle forme est avantageusement simple à manufacturer.In yet another particular embodiment, the cam is of frustoconical shape. Such a form is advantageously simple to manufacture.
Dans encore un mode de réalisation particulière, le mobile entraîneur est monté libre en rotation autour dudit axe fileté. Par conséquent, on obtient une construction simple.In yet another particular embodiment, the driving carrier is rotatably mounted about said threaded axis. Therefore, we obtain a simple construction.
Dans un autre mode de réalisation particulier, le palpeur comprend un galet en contact avec ladite surface inclinée de ladite came et monté libre en rotation sur une bascule du palpeur, le galet étant de préférence en rubis. Les frottements entre le palpeur et la came sont ainsi minimisés, réduisant en conséquence l'usure de ces parties. De préférence, le plan dudit galet est agencé perpendiculairement à une tangente de ladite surface extérieure de ladite came.In another particular embodiment, the probe comprises a roller in contact with said inclined surface of said cam and rotatably mounted on a flip-flop of the probe, the roller preferably being ruby. The friction between the probe and the cam is thus minimized, thereby reducing the wear of these parts. Preferably, the plane of said roller is arranged perpendicular to a tangent of said outer surface of said cam.
L'invention concerne en outre un mouvement d'horlogerie comprenant un barillet dans lequel est logé un ressort moteur, le barillet étant en liaison cinématique avec un mobile denté destiné à être mis en rotation selon les deux sens de rotation lors du remontage et du dévidement du ressort moteur, et un mécanisme indicateur de réserve de marche comme défini ci-dessus, ledit axe fileté étant solidarisé à un élément de bâti dudit mouvement d'horlogerie et ledit mobile entraîneur étant en liaison cinématique avec ledit mobile denté.The invention furthermore relates to a clockwork movement comprising a barrel in which a motor spring is housed, the barrel being in kinematic connection with a toothed gear intended to be rotated in the two directions of rotation during reassembly and unwinding. of the mainspring, and a power reserve indicator mechanism as defined above, said threaded axis being secured to a frame member of said clockwork movement and said driving mobile being in kinematic connection with said toothed mobile.
De préférence, ledit mobile denté est un tambour du barillet et/ou ledit mobile denté engrène directement avec ledit mobile entraîneur.Preferably, said toothed mobile is a barrel drum and / or said toothed gear meshes directly with said driving mobile.
Finalement, l'invention concerne une pièce d'horlogerie comprenant un mouvement d'horlogerie, de préférence une montre-bracelet, comme définie ci-dessus.Finally, the invention relates to a timepiece comprising a watch movement, preferably a wristwatch, as defined above.

Les
Une came 3 est engagée sur l'axe fileté 2 et comporte un taraudage non représenté, agencé pour coopérer par vissage avec l'axe fileté 2 de telle sorte qu'une rotation de la came 3 entraîne son déplacement le long de l'axe fileté. La came 3 présente une surface extérieure 7 inclinée par rapport audit axe. Bien que la came 3 ait été illustrée comme possédant une forme tronconique, d'autres formes sont également possibles, par exemple une forme présentant une surface extérieure 7 convexe ou concave.A
Un mobile entraîneur 10 de ladite came 3 est monté libre en rotation autour de l'axe fileté 2 sur un épaulement 11 dépourvu de filets, éventuellement par l'intermédiaire d'un noyau intermédiaire 12 en forme de bague annulaire, de préférence en rubis.A driving mobile 10 of said
Le mobile entraîneur 10 comporte des moyens d'entraînement en rotation de la came 3. Dans le cas d'espèce, ces moyens d'entraînement sont constitués par deux tenons 4 fixés solidairement sur le noyau du mobile entraîneur 10 et s'étendant substantiellement perpendiculairement au plan de ce dernier, et substantiellement parallèle à l'axe fileté 2. Ces tenons 4 passent à travers des ouvertures correspondantes 13 pratiquées dans la came 3, qui peut se déplacer le long des tenons, les tenons 4 et les ouvertures 13 étant dimensionnés de telle sorte que la came 3 soit guidée par les tenons 4. Naturellement, d'autres formes de moyens d'entraînement en rotation de la came 3 sont envisageables, et le nombre de ces moyens d'entraînement peut être choisi selon le souhait de l'horloger. Par exemple, il est aussi envisageable de remplacer les tenons 4 par une forme géométrique telle qu'une étoile, polygone ou similaire, que comporte le moyeu du mobile entraîneur 10, et qui fait également office de moyen d'entraînement, de la même manière que les tenons 4. Cette forme géométrique interagit avec une cavité de forme correspondante dans la base de la came 3, ce qui a pour effet que les moyens d'entrainement de la came 3 sont cachés et effectivement invisibles du côté pont (vus depuis le sommet du cône).The
Le mobile entraîneur 10 est adapté à être entraîné lui-même par la rotation dans les deux sens d'un élément tournant du barillet, par exemple son tambour ou son axe. Dans le cas d'un barillet (non illustrée) associé à un mécanisme de fusée, dans laquelle le tambour du barillet est lié à la fusée par une chaîne, une corde, ou similaire, il est conventionnel que le tambour du barillet tourne, l'axe de barillet étant fixe. Dans le présent cas, le mobile entraîneur 10 est pourvu d'une denture extérieure 14, qui est destinée à être entraîné directement ou indirectement par une denture située de manière habituelle en saillie du pourtour du tambour du barillet.The driving mobile 10 is adapted to be driven itself by the rotation in both directions of a rotating element of the barrel, for example its drum or its axis. In the case of a barrel (not shown) associated with a rocket mechanism, in which the drum of the barrel is connected to the rocket by a chain, a rope, or the like, it is conventional that the barrel of the barrel rotates, barrel axis being fixed. In this case, the driving
Le mécanisme 1 comprend en outre un palpeur 5 pivoté dans un élément du bâti du mouvement d'horlogerie (non illustré), une extrémité 17 du palpeur étant maintenue en contact avec la surface extérieure 7 de la came 3 par un moyen de rappel (non illustré). De manière connue, l'extrémité 17 du palpeur 5 suit la surface extérieure 7 lors du déplacement de la came 3 le long de l'axe fileté 2. De manière avantageuse, l'extrémité 17 du palpeur 5 est munie à son extrémité d'un galet 6 monté libre en rotation sur le palpeur, et servant de suiveur de came. Afin de réduire les frottements, le galet 6 peut être en rubis ou être muni d'un revêtement approprié.The
Le palpeur 5 est associé à une crémaillère 15 en liaison cinématique avec un pignon 16 associé à un indicateur de réserve de marche (non illustré) tel qu'une aiguille, une disque, ou similaire. De manière alternative, la crémaillère 15 peut être remplacée par un râteau. Le type de liaison entre la crémaillère 15 et le pignon 16 est à la portée de l'homme du métier et n'a pas besoin d'être décrit en détail.The
Le principe de fonctionnement du mécanisme indicateur 1 de réserve de marche sera maintenant décrit en référence au mode de réalisation des
Dans la configuration illustrée dans les figures, le ressort moteur du barillet (non illustré) auquel le mécanisme indicateur 1 de réserve de marche est associé est dans un état désarmé. Par conséquent, la came 3 se trouve proche du mobile entraîneur 10, et le galet 6 se trouve en contact avec la surface inclinée 7 près du diamètre le moins important de la came 3.In the configuration illustrated in the figures, the mainspring of the cylinder (not illustrated) to which the power
Lors du remontage du ressort moteur, le mobile entraîneur 10 est mis en rotation selon un premier sens de rotation, par exemple dû à la rotation du tambour de barillet. Grâce aux tenons 4, la came 3 est mise en rotation autour de l'axe fileté 2 selon le premier sens de rotation. L'axe fileté 2 étant fixe, la came 3 se déplace, grâce aux filetages, le long de l'axe fileté 2 en s'éloignement au mobile entraîneur 10, les ouvertures 13 étant guidées par les tenons 4.During reassembly of the mainspring, the driving mobile 10 is rotated in a first direction of rotation, for example due to the rotation of the barrel drum. With the
Lorsque la came 3 se déplace le long de l'axe fileté 2, l'extrémité 17 du palpeur 5 suit la surface inclinée 7 de la came 3, qui est de diamètre croissant, en direction du mobile entraîneur 10. Par conséquent, le palpeur est pivoté autour de son axe de pivotement, actionnant ainsi le pignon 16 par l'intermédiaire de la crémaillère 15. Par conséquent, l'indicateur de réserve de marche (non illustré) est déplacé de manière à indiquer une réserve de marche croissante.When the
Lors du dévidement du ressort moteur, le mobile entraîneur 10 est mis en rotation dans un second sens de rotation opposé au premier sens de rotation, la came 3 étant ainsi déplacée en direction du mobile entraîneur 10. Les actions décrites dans le paragraphe précédent s'inversent, l'indicateur de réserve de marche (non illustré) étant déplacé de manière à indiquer une réserve de marche diminuant.During unwinding of the motor spring, the driving
Il est évident pour l'homme du métier qu'un mécanisme de réserve de marche selon l'invention peut être agencé de manière différente de celui illustré dans les figures, tout en fonctionnant de manière équivalente. Par exemple, il est envisageable que la forme de la came 3 soit agencée selon une forme inverse que celle illustrée dans les
Bien que l'invention ait été divulguée en référence à un mode de réalisation spécifique, l'invention n'est pas limitée à cet exemple particulier. Le mécanisme indicateur de réserve de marche peut être modifié par l'homme du métier sans sortir du cadre de l'invention défini par les revendications annexées.Although the invention has been disclosed with reference to a specific embodiment, the invention is not limited to this particular example. The power reserve indicator mechanism may be modified by those skilled in the art without departing from the scope of the invention defined by the appended claims.
