Description

Domaine de l'inventionField of the invention

L'invention se rapporte à un mécanisme de remontage d'une pièce d'horlogerie comprenant au moins un premier accumulateur d'énergie agencé pour alimenter en énergie un premier mécanisme et un second accumulateur d'énergie agencé pour alimenter en énergie un second mécanisme, ledit mécanisme de remontage comportant une tige de remontoir, un pignon de remontoir et un pignon coulant portés par ladite tige de remontoir et présentant en regard l'un de l'autre des dentures droites agencées pour permettre l'entrainement du pignon de remontoir par le pignon coulant dans les deux sens de rotation de la tige de remontoir, ladite tige de remontoir et le pignon coulant occupant une même position axiale de remontage. L'invention se rapporte également à une pièce d'horlogerie comprenant un tel mécanisme de remontage.The invention relates to a winding mechanism of a timepiece comprising at least a first energy accumulator arranged to supply power to a first mechanism and a second energy accumulator arranged to supply power to a second mechanism, said winding mechanism comprising a winding stem, a winding pinion and a sliding pinion carried by said winding stem and having opposite to each other straight teeth arranged to allow the driving of the winding pinion by the pinion flowing in both directions of rotation of the winding stem, said winding stem and the sliding pinion occupying the same axial position of winding. The invention also relates to a timepiece comprising such a winding mechanism.

Arrière-plan de l'inventionBackground of the invention

Un tel mécanisme de remontage est par exemple décrit dans le brevet CH 330202 . Ce document décrit une montre-réveil comprenant un premier accumulateur d'énergie constitué par le barillet de mouvement et un second accumulateur d'énergie constitué par le barillet de sonnerie. Le mécanisme comprend une tige de remontoir agencée pour effectuer toutes les commandes du mouvement et du réveil, et notamment la mise à l'heure du mouvement et de la sonnerie, mais également le remontage du barillet de mouvement ou du barillet de sonnerie en tournant dans un sens ou dans l'autre la tige de remontoir lorsqu'elle occupe sa position médiane de remontage. A cet effet, le pignon coulant est en prise avec le pignon de remontoir par des dents de forme droite, et il est prévu une roue de couronne en prise avec le pignon de remontoir, et deux renvois de couronne, engrenant tous deux avec la roue de couronne et destinés à coopérer respectivement avec le rochet de chacun des barillets. L'engrènement des renvois de couronne avec le rochet du barillet correspondant est assuré par un ressort qui agit sur les axes des renvois de couronne pour les pousser et les amener en prise avec le rochet correspondant. Lorsque la tige de remontoir est tournée dans un sens ou dans l'autre, par l'effort tangentiel exercé par la roue de couronne sur les renvois, l'un des renvois de couronne opère le remontage du barillet correspondant tandis que l'autre fait décliquetage. Le décliquetage entraine la persistance d'un contact faible et cyclique. Un tel mécanisme est fragile du fait de la sollicitation permanente du ressort pour assurer un bon engrènement des renvois de couronne avec le rochet correspondant. Une perte d'efficacité du ressort, par fatigue ou par vieillissement, entraine le risque que l'un ou l'autre des renvois ne coopère plus avec le rochet correspondant de sorte que le barillet associé ne pourra plus être remonté. Un autre inconvénient est l'usure des renvois de couronne lors du décliquetage. De plus, cette construction impose un contrôle des tolérances de fabrication du ressort.Such a winding mechanism is for example described in the patent CH 330202 . This document describes an alarm watch comprising a first energy accumulator constituted by the movement barrel and a second energy accumulator constituted by the striking barrel. The mechanism comprises a winding stem arranged to perform all the commands of the movement and the alarm clock, including setting the time of movement and ringing, but also the winding of the barrel of movement or the barrel of ringing by turning in one way or the other the winding stem when it occupies its middle winding position. For this purpose, the sliding pinion is engaged with the winding pinion by teeth of straight shape, and there is provided a crown wheel engaged with the winding pinion, and two crown gear, meshing both with the crown wheel and intended to cooperate respectively with the ratchet of each of the barrels. The meshing of the crown gear with the ratchet of the corresponding barrel is provided by a spring which acts on the axes of the crown gear to push them and bring them into engagement with the corresponding ratchet. When the winding stem is turned in one direction or the other, by the tangential force exerted by the crown wheel on the returns, one of the crown returns operates the winding of the corresponding cylinder while the other makes unlatching. The unclamping causes the persistence of a weak and cyclic contact. Such a mechanism is fragile due to the permanent solicitation of the spring to ensure a good meshing of the crown returns with the corresponding ratchet. A loss of efficiency of the spring, by fatigue or aging, entails the risk that one or other of the referrals no longer cooperate with the corresponding ratchet so that the associated cylinder can not be reassembled. Another disadvantage is the wear of the crown gear during unclipping. In addition, this construction imposes a control of the manufacturing tolerances of the spring.

Le brevet CH 47977 décrit également un mécanisme de remontage et de mise à l'heure de montre-réveil à deux barillets. Ce mécanisme comprend un rochet de remontage du barillet de mouvement constamment en prise avec une roue de couronne engrenant avec un pignon de remontoir, et disposé pour n'actionner l'arbre de barillet de mouvement que dans un sens de rotation de la tige. Le rochet de remontage du barillet de mouvement est utilisé pour transmettre le mouvement inverse de rotation de la tige soit au rochet de remontage du barillet de réveil soit à la roue de réveil par un renvoi pivoté sur une bascule manoeuvrable depuis l'extérieur de la montre. Ce mécanisme présente l'inconvénient de nécessiter l'actionnement d'une commande extérieure en plus de la rotation de la tige de remontoir pour remonter le barillet de sonnerie.The patent CH 47977 also discloses a mechanism for winding and setting the watch clock to two barrels. This mechanism comprises a winding ratchet of the movement barrel constantly engaged with a crown wheel meshing with a winding pinion, and arranged to actuate the movement barrel shaft only in a direction of rotation of the rod. The winding ratchet of the movement barrel is used to transmit the reverse movement of rotation of the rod to the winding ratchet of the revolving barrel or to the waking wheel by a pivoted return on a rocker operable from outside the watch . This mechanism has the disadvantage of requiring the actuation of an external control in addition to the rotation of the winding stem to raise the barrel of ringing.

L'invention a également pour objectif de fournir un mécanisme de remontage permettant le remontage de deux accumulateurs d'énergie présentant une grande modularité dans le choix du positionnement des différents éléments du mécanisme, ainsi que dans le choix du sens de remontage des accumulateurs d'énergie.The invention also aims to provide a winding mechanism for the reassembly of two energy accumulators having a high degree of modularity in the choice of the positioning of the various elements of the mechanism, as well as in the choice of the direction of reassembly of the accumulators of energy.

A cet effet, la présente invention concerne un mécanisme de remontage d'une pièce d'horlogerie comprenant au moins un premier accumulateur d'énergie agencé pour alimenter en énergie un premier mécanisme et un second accumulateur d'énergie agencé pour alimenter en énergie un second mécanisme, ledit mécanisme de remontage comportant une tige de remontoir, un pignon de remontoir et un pignon coulant portés par ladite tige de remontoir et présentant en regard l'un de l'autre des dentures droites agencées pour permettre l'entrainement du pignon de remontoir par le pignon coulant dans les deux sens de rotation de la tige de remontoir, ladite tige de remontoir et le pignon coulant occupant une même position axiale de remontage.To this end, the present invention relates to a winding mechanism of a timepiece comprising at least a first energy accumulator arranged to supply energy to a first mechanism and a second energy accumulator arranged to supply energy to a second mechanism, said winding mechanism comprising a winding stem, a winding pinion and a sliding pinion carried by said winding stem and having opposite to each other straight teeth arranged to allow the driving of the winding pinion by the pinion flowing in both directions of rotation of the winding stem, said winding stem and the sliding pinion occupying the same axial position of winding.

Selon l'invention, ladite tige de remontoir est logée dans une platine de manière à ce que le pignon de remontoir soit opérationnel de part et d'autre de la tige de remontoir par rapport à la platine et le mécanisme de remontage comprend un premier et un second dispositifs d'embrayage/débrayage disposés de part et d'autre de la tige de remontoir par rapport à la platine, coopérant avec le pignon de remontoir et agencés pour que l'un des premier et second dispositifs d'embrayage/débrayage occupe une position d'embrayage pour embrayer le pignon de remontoir et le premier accumulateur d'énergie tandis que l'autre des premier et second dispositifs d'embrayage/débrayage occupe une position de débrayage pour débrayer le second accumulateur d'énergie lorsque la tige de remontoir est tournée dans un sens, et occupe une position de débrayage pour débrayer le premier accumulateur d'énergie tandis que l'autre des premier et second dispositifs d'embrayage/débrayage occupe une position d'embrayage pour embrayer le pignon de remontoir et le second accumulateur d'énergie lorsque la tige de remontoir est tournée dans l'autre sens.According to the invention, said winding stem is housed in a plate so that the winding pinion is operational on both sides of the winding stem relative to the plate and the winding mechanism comprises a first and a second device clutch / clutch disposed on either side of the winding stem relative to the plate, cooperating with the winding pinion and arranged so that one of the first and second clutch / clutch devices occupies a position of clutch for engaging the winder pinion and the first energy accumulator while the other of the first and second clutch / disengagement devices is in a disengaged position for disengaging the second energy accumulator when the winding stem is turned in one direction, and occupies a disengaging position to disengage the first energy accumulator while the other of the first and second clutch / disengagement devices occupies a clutch position to engage the winding pinion and the second clutch accumulator. energy when the winding stem is turned in the other direction.

Ainsi, le mécanisme de remontage selon l'invention permet de remonter deux accumulateurs d'énergie par la seule rotation de la tige de remontoir dans un sens et dans l'autre.Thus, the winding mechanism according to the invention makes it possible to go up two energy accumulators by the single rotation of the winding stem in one direction and the other.

De plus, chaque accumulateur d'énergie est remonté au moyen de son propre dispositif d'embrayage/débrayage garantissant une meilleure fiabilité du mécanisme de remontage. Le débrayage signifie une absence totale de contact et donc la suppression du risque d'usure, contrairement à un décliquetage.In addition, each energy accumulator is reassembled by means of its own clutch / disengagement device ensuring a better reliability of the winding mechanism. The disengagement means a total absence of contact and therefore the elimination of the risk of wear, unlike unclipping.

Le mécanisme de remontage selon l'invention est particulièrement approprié pour remonter un barillet de mouvement constituant l'un des accumulateurs d'énergie et pour remonter un barillet d'un automate indépendant constituant l'autre des accumulateurs d'énergie.The winding mechanism according to the invention is particularly suitable for assembling a movement barrel constituting one of the energy accumulators and for mounting a barrel of an independent automaton constituting the other of the energy accumulators.

La présente invention concerne également une pièce d'horlogerie comprenant un mécanisme de remontage tel que défini ci-dessus.The present invention also relates to a timepiece comprising a winding mechanism as defined above.

La présente invention concerne un mécanisme de remontage d'au moins deux accumulateurs d'énergie prévus dans une pièce d'horlogerie. Ces deux accumulateurs peuvent être indépendants l'un de l'autre ou liés, par exemple au niveau de la décharge. Plus particulièrement, dans la description qui suit, les deux accumulateurs d'énergie sont indépendants ou autonomes, l'un des accumulateurs d'énergie étant un barillet de mouvement alimentant en énergie le mouvement de base de la pièce d'horlogerie et l'autre des accumulateurs d'énergie étant un barillet d'automate alimentant un automate prévu dans la pièce d'horlogerie. Il est bien évident que les accumulateurs d'énergie peuvent être utilisés pour alimenter en énergie tout autre mécanisme d'une pièce d'horlogerie, par exemple un mécanisme de sonnerie, de seconde morte ou de réveil, ou tout autre mécanisme approprié.The present invention relates to a winding mechanism of at least two energy accumulators provided in a timepiece. These two accumulators can be independent of each other or linked, for example at the discharge. More particularly, in the description that follows, the two energy accumulators are independent or autonomous, one of the energy accumulators being a movement cylinder supplying energy to the base movement of the timepiece and the other energy accumulators being an automaton barrel feeding an automaton provided in the timepiece. It is obvious that the energy accumulators can be used to supply energy to any other mechanism of a timepiece, for example a striking mechanism, dead second or alarm clock, or any other appropriate mechanism.

Dans l'exemple décrit ci-dessous, le premier accumulateur d'énergie est le barillet de mouvement et le second accumulateur d'énergie est le barillet d'automate. Il est toutefois bien évident que les rôles peuvent être inversés, le caractère « premier » ou « second » attribué dans la présente description au barillet de mouvement, respectivement au barillet d'automate n'étant pas limitatif.In the example described below, the first energy accumulator is the movement barrel and the second energy accumulator is the automaton barrel. It is however quite obvious that the roles can be reversed, the character "first" or "second" attributed in this description to the barrel of movement, respectively to the barrel of automaton is not limiting.

En référence à la figure 1, il est représenté un mécanisme de remontage 1 d'une pièce d'horlogerie qui comporte d'une manière classique une tige de remontoir 2 sur laquelle sont montés un pignon de remontoir 4 et un pignon coulant 6. La tige de remontoir 2 est logée dans une platine 7 et est agencée pour occuper au moins deux positions axiales, à savoir une première position de remontage dans laquelle la rotation de la tige de remontoir dans un sens (ici sens horaire) entraine l'armage du barillet de mouvement et la rotation de la tige de remontoir dans l'autre sens (ici antihoraire) entraine l'armage du barillet d'automate comme on le verra ci-dessous, et une deuxième position de mise à l'heure dans laquelle la rotation de la tige de remontoir dans les deux sens horaire et antihoraire permet la mise à l'heure du mouvement, aucun des premier et second accumulateurs d'énergie ne pouvant alors être armé, quel que soit le sens de rotation de la tige de remontoir. D'une manière connue de l'homme du métier, le pignon de remontoir 4 est monté libre en rotation sur une partie cylindrique de la tige de remontoir 2. Le pignon coulant 6 présente un trou carré et est monté coulissant sur un carré correspondant prévu à l'extrémité de la tige de remontoir 2. Le pignon coulant 6 peut ainsi coulisser entre la position de remontage dans laquelle il engrène avec le pignon de remontoir 4 et la position de mise à l'heure dans laquelle le pignon coulant 6 est séparé du pignon de remontoir 4 et engrène avec le mécanisme de mise à l'heure. Le déplacement du pignon coulant 6 est assuré par un mécanisme comprenant une tirette et une bascule. Tous ces éléments et mécanismes sont connus de l'homme du métier et ne nécessitent pas de description plus détaillée.With reference to the figure 1 , there is shown a winding mechanism 1 of a timepiece which comprises in a conventional manner a winding stem 2 on which are mounted a winding pinion 4 and a sliding pinion 6. The winding stem 2 is housed in a plate 7 and is arranged to occupy at least two axial positions, namely a first winding position in which the rotation of the winding stem in one direction (here clockwise) causes the winding of the movement barrel and the rotation the winding stem in the other direction (here counterclockwise) causes the winding of the automaton barrel as will be seen below, and a second setting position in which the rotation of the winding stem in both the clockwise and counterclockwise directions allows the setting of the time of movement, none of the first and second energy accumulators can then be armed regardless of the direction of rotation of the winding stem. In a manner known to those skilled in the art, the winding pinion 4 is rotatably mounted on a cylindrical portion of the winding stem 2. The sliding pinion 6 has a square hole and is slidably mounted on a corresponding square provided at the end of the winding stem 2. The sliding pinion 6 can thus slide between the winding position in which it meshes with the winding pinion 4 and the setting time setting position in which the sliding pinion 6 is separated winding pinion 4 and meshes with the time setting mechanism. The displacement of the sliding pinion 6 is provided by a mechanism comprising a pull rod and a rocker. All these elements and mechanisms are known to those skilled in the art and do not require a more detailed description.

On notera toutefois qu'à la différence des mécanismes de remontage classiques, le pignon coulant et le pignon de remontoir ne s'engrènent pas par une denture Breguet mais présentent en regard l'un de l'autre des dentures de chant droites agencées pour permettre l'entrainement du pignon de remontoir 4 par le pignon coulant 6 dans les deux sens de rotation horaire et antihoraire de la tige de remontoir 2, ladite tige de remontoir 2 et le pignon coulant 6 occupant une même position axiale de remontage.Note however that unlike conventional winding mechanisms, the sliding pinion and the winding pinion do not mesh with a Breguet toothing but have opposite of each other straight edge teeth arranged to allow the driving of the winding pinion 4 by the sliding pinion 6 in both clockwise and counterclockwise rotation of the winding stem 2, said winding stem 2 and the sliding pinion 6 occupying the same axial winding position.

En référence plus particulièrement aux figures 11 à 13, les dentures de chant droites du pignon coulant 6 et du pignon de remontoir 4 peuvent être des dentures à crabot. A cet effet, le pignon de remontoir 4 et le pignon coulant 6 présentent respectivement, au lieu d'une denture Breguet, des dents 8 en forme de créneaux se terminant par deux faces inclinées se joignant au sommet du créneau et alternant avec des évidements 10 de forme complémentaire à celle des dents 8 permettant leur engrènement par l'engagement des dents 8 de l'un dans les évidements correspondants 10 de l'autre. Cette forme de dentures de chant à crabot permet au pignon coulant 6 de venir s'emboiter (se « craboter ») facilement dans le pignon de remontoir 4, et de transmettre plus de couple lorsqu'ils sont en position de remontage, comme le montre la figure 13. Ces dentures de chant à crabot sont également usinables sans grande contrainte. D'une manière connue en soi, le pignon de remontoir 4 comprend également une denture périphérique 12 agencée pour coopérer avec les premier et second dispositifs d'embrayage/débrayage comme cela sera détaillé ci-dessous. Le pignon coulant 6 comprend également une denture de chant 14, opposée à la denture de chant à crabots 8, agencée pour coopérer avec le mécanisme de mise à l'heure.With particular reference to Figures 11 to 13 the straight edge teeth of the sliding pinion 6 and of the winding pinion 4 may be dog teeth. For this purpose, the winding pinion 4 and the sliding pinion 6 respectively have, in place of a Breguet toothing, teeth 8 in the form of crenellations ending in two inclined faces joining the top of the crenel and alternating with recesses 10. of complementary shape to that of the teeth 8 allowing their meshing by the engagement of the teeth 8 of one in the corresponding recesses 10 of the other. This form of dog-toed toothings allows the sliding pinion 6 to come to fit easily ("clutch") in the winding pinion 4, and to transmit more torque when in the winding position, as shown in FIG. the figure 13 . These claw teeth are also machinable without great strain. In a manner known per se, the winding pinion 4 also comprises a peripheral toothing 12 arranged to cooperate with the first and second clutch / disengagement devices as will be detailed below. The sliding pinion 6 also comprises a toothing of edge 14, opposite the jaw teeth to jaw 8, arranged to cooperate with the setting mechanism.

Conformément à l'invention, et en référence aux figures 1 à 4, le mécanisme de remontage comprend un premier dispositif d'embrayage/débrayage 16 et un second dispositif d'embrayage/débrayage 18 disposés de part et d'autre de la tige de remontoir 2 par rapport à la platine 7, lesdits premier et second dispositifs d'embrayage/débrayage 16 et 18 coopérant chacun avec le pignon de remontoir 4. A cet effet, la tige de remontoir 2 est avantageusement logée dans la platine 7 de manière à ce que le pignon de remontoir 4 soit opérationnel de part et d'autre de la tige de remontoir 2 par rapport à la platine 7. Cela signifie que le pignon de remontoir 4 est disposé dans un logement prévu dans la platine 7 et les organes autour du pignon de remontoir 4 sont agencés de sorte que le pignon de remontoir 4 puisse engrener avec chacun des premier et second dispositifs d'embrayage/débrayage 16 et 18 placés de part et d'autre de la tige de remontoir 2 par rapport à la platine 7.In accordance with the invention, and with reference to Figures 1 to 4 , the winding mechanism comprises a first clutch / clutch device 16 and a second clutch / clutch device 18 arranged on either side of the winding stem 2 relative to the plate 7, said first and second devices clutch / clutch 16 and 18 each cooperating with the winding pinion 4. For this purpose, the winding stem 2 is advantageously housed in the plate 7 so that the winding pinion 4 is operational on both sides. other of the winding stem 2 relative to the plate 7. This means that the winding pinion 4 is disposed in a housing provided in the plate 7 and the members around the winding pinion 4 are arranged so that the winding pinion 4 can mesh with each of the first and second clutch / clutch devices 16 and 18 placed on either side of the winding stem 2 relative to the plate 7.

En outre, les premier et second dispositifs d'embrayage/débrayage 16 et 18 sont agencés pour que l'un des premier et second dispositifs d'embrayage/débrayage 16, 18 :

  • occupe une position d'embrayage pour embrayer le pignon de remontoir 4 et le premier accumulateur d'énergie tandis que l'autre des premier et second dispositifs d'embrayage/débrayage 16, 18 occupe une position de débrayage pour débrayer le second accumulateur d'énergie lorsque la tige de remontoir 2 est tournée dans un sens, et
  • occupe une position de débrayage pour débrayer le premier accumulateur d'énergie tandis que l'autre des premier et second dispositifs d'embrayage/débrayage 16, 18 occupe une position d'embrayage pour embrayer le pignon de remontoir 4 et le second accumulateur d'énergie lorsque la tige de remontoir 2 est tournée dans l'autre sens.
In addition, the first and second clutch / clutch devices 16 and 18 are arranged so that one of the first and second clutch / clutch devices 16, 18:
  • occupies a clutch position to engage the winding pinion 4 and the first energy accumulator while the other of the first and second clutch / clutch devices 16, 18 occupies a position of disengaging to disengage the second energy accumulator when the winding stem 2 is turned in one direction, and
  • occupies a disengaging position to disengage the first energy accumulator while the other of the first and second clutch / disengagement devices 16, 18 occupies a clutch position to engage the winding pinion 4 and the second accumulator energy when the winding stem 2 is turned in the other direction.

Selon l'invention, l'un des premier et second dispositifs d'embrayage/débrayage 16, 18, en l'occurrence ici arbitrairement le premier dispositif d'embrayage/débrayage 16, comprend une première roue de couronne 20 coopérant avec la denture périphérique 12 du pignon de remontoir 4 et sur laquelle est montée une première bascule d'embrayage 22. Ladite première bascule d'embrayage 22 porte à son extrémité libre un premier pignon entraineur 24 agencé pour pouvoir relier cinématiquement la première roue de couronne 20 au premier accumulateur d'énergie 26, ici le barillet de mouvement. Plus particulièrement, le premier pignon entraineur 24 est positionné sur la première bascule d'embrayage 22 et agencé d'une part pour engrener avec la première roue de couronne 20 et d'autre part pour pouvoir engrener avec un premier rochet 28 coopérant avec le premier accumulateur d'énergie 26. Il est bien évident que, dans une autre variante non représentée selon laquelle l'armage du barillet de mouvement se fait par le tambour afin de faire tourner le barillet dans le sens opposé, le premier pignon entraineur sera alors agencé pour engrener avec le tambour dudit barillet.According to the invention, one of the first and second clutch / disengagement devices 16, 18, in this case here arbitrarily the first clutch / clutch device 16, comprises a first crown gear 20 cooperating with the peripheral toothing. 12 of the winding pinion 4 and on which is mounted a first clutch rocker 22. Said first clutch rocker 22 carries at its free end a first driving pinion 24 arranged to be able to kinematically connect the first crown wheel 20 to the first accumulator of energy 26, here the barrel of movement. More particularly, the first driving pinion 24 is positioned on the first clutch rocker 22 and arranged on the one hand to mesh with the first crown wheel 20 and on the other hand to be able to mesh with a first ratchet 28 cooperating with the first energy accumulator 26. It is obvious that, in another variant not shown in which the winding of the barrel of movement is by the drum in order to rotate the barrel in the opposite direction, the first driving pinion will be arranged to mesh with the drum of said barrel.

Ladite première bascule d'embrayage 22 est montée libre sur l'axe de ladite première roue de couronne 20 et le premier pignon entraineur 24 est monté à friction sur ladite première bascule d'embrayage 22, de sorte que, tant que le premier dispositif d'embrayage 16 n'occupe pas sa position d'embrayage, ladite première bascule d'embrayage 22 et le premier pignon entraineur 24 pivotent solidairement avec ladite première roue de couronne 20 pour passer :

  • en position d'embrayage et lier cinématiquement le premier pignon entraineur 24 au premier rochet 28 du premier accumulateur d'énergie 26 puis, une fois le premier pignon entraineur 24 au contact du premier rochet 28 du premier accumulateur d'énergie 26, la première bascule d'embrayage 22 est empêchée de continuer à pivoter et le premier pignon entraineur 24 se désolidarise de la première bascule d'embrayage 22 grâce à la friction, permettant ainsi l'entrainement du premier pignon entraineur 24 par le pignon de remontoir 4 via la première roue de couronne 20 pour remonter le premier accumulateur d'énergie 26 lorsque la tige de remontoir 2 est tournée dans un premier sens, par exemple le sens horaire,
  • en position de débrayage en éloignant le premier pignon entraineur 24 du premier accumulateur d'énergie 26 lorsque la tige de remontoir 2 est tournée dans un second sens inverse, dans ce cas le sens antihoraire.
Said first clutch rocker 22 is freely mounted on the axis of said first crown wheel 20 and the first driving pinion 24 is frictionally mounted on said first clutch rocker 22, so that as long as the first clutch rocker 22 clutch 16 does not occupy its clutch position, said first clutch rocker 22 and the first gear coach 24 pivot integrally with said first crown wheel 20 to pass:
  • in the clutch position and kinematically bind the first driving pinion 24 to the first ratchet 28 of the first energy accumulator 26 and, once the first driving pinion 24 in contact with the first ratchet 28 of the first energy accumulator 26, the first latch clutch 22 is prevented from continuing to pivot and the first driving pinion 24 is disengaged from the first clutch rocker 22 thanks to the friction, thus allowing the first driving pinion 24 to be driven by the winding pinion 4 via the first crown wheel 20 for refitting the first energy accumulator 26 when the winding stem 2 is turned in a first direction, for example clockwise,
  • in the disengaged position by moving the first driving gear 24 away from the first energy accumulator 26 when the winding stem 2 is rotated in a second opposite direction, in this case counterclockwise.

Dans l'exemple décrit ici, le premier dispositif d'embrayage/débrayage 16 est disposé côté mouvement pour assurer le remontage du barillet de mouvement.In the example described here, the first clutch / clutch device 16 is disposed on the movement side to reassemble the movement barrel.

De l'autre côté de la platine 7, opposé au mouvement, il est prévu une planche 30 sur laquelle sont montés les éléments du mécanisme de l'automate, et notamment le second accumulateur d'énergie 27, ici le barillet d'automate, et l'autre des premier et second dispositifs d'embrayage/débrayage 16, 18, ici le second dispositif d'embrayage/débrayage 18, comme le montre la figure 3. Ainsi, dans la variante représentée, les premier et second accumulateurs d'énergie sont disposés de part et d'autre de la tige de remontoir 2 par rapport à la platine 7. Il est bien évident que dans une variante non représentée, les premier et second accumulateurs d'énergie peuvent être disposés du même côté, des mobiles intermédiaires étant alors utilisés pour lier cinématiquement chaque dispositif d'embrayage/débrayage à son accumulateur d'énergie associé.On the other side of the plate 7, opposed to the movement, there is provided a board 30 on which are mounted the elements of the automaton mechanism, and in particular the second energy accumulator 27, here the automaton barrel, and the other of the first and second clutch / clutch devices 16, 18, here the second clutch / clutch device 18, as shown in FIG. figure 3 . Thus, in the variant shown, the first and second energy accumulators are arranged on either side of the winding stem 2 relative to the plate 7. It is obvious that in a variant not shown, the first and second second energy accumulators can be arranged on the same side, intermediate mobiles being then used to kinematically link each clutch / disengagement device to its associated energy accumulator.

Le second dispositif d'embrayage/débrayage 18 comprend un pignon de remontoir intermédiaire 32 monté sur le châssis du mouvement et coopérant avec la denture périphérique 12 du pignon de remontoir 4 qui est agencé pour que sa denture périphérique 12 soit accessible et opérationnelle également de ce côté de la pièce d'horlogerie, c'est-à-dire côté planche ou côté automate. Le second dispositif d'embrayage/débrayage 18 comprend également une seconde roue de couronne 34 coopérant avec le pignon de remontoir 4 via le pignon de remontoir intermédiaire 32, et sur laquelle est montée une seconde bascule d'embrayage 36. Ladite seconde bascule d'embrayage 36 porte à son extrémité libre un second pignon entraineur 38 agencé pour pouvoir relier cinématiquement la seconde roue de couronne 34 au second accumulateur d'énergie 27, ici le barillet d'automate. Plus particulièrement, le second pignon entraineur 38 est positionné sur la seconde bascule d'embrayage 36 et agencé d'une part pour engrener avec la seconde roue de couronne 34 et d'autre part pour pouvoir engrener avec un second rochet 40 coopérant avec le second accumulateur d'énergie 27. Il est bien évident que, dans une autre variante non représentée selon laquelle l'armage du barillet d'automate se fait par le tambour afin de faire tourner le barillet dans le sens opposé, le premier pignon entraineur sera alors agencé pour engrener avec le tambour dudit barillet.The second clutch / clutch device 18 comprises an intermediate winding pinion 32 mounted on the chassis of the movement and cooperating with the peripheral set of teeth 12 of the winding pinion 4 which is arranged so that its peripheral toothing 12 is accessible and operational also from this side of the timepiece, that is to say, side board or PLC side. The second clutch / clutch device 18 also comprises a second crown wheel 34 cooperating with the winding pinion 4 via the intermediate winding pinion 32, and on which is mounted a second clutch lever 36. Said second rocker arm clutch 36 carries at its free end a second driving pinion 38 arranged to be able to kinematically connect the second crown wheel 34 to the second energy accumulator 27, here the automaton barrel. More particularly, the second drive gear 38 is positioned on the second clutch lever 36 and arranged on the one hand to mesh with the second crown wheel 34 and on the other hand to be able to mesh with a second ratchet 40 cooperating with the second energy accumulator 27. It is obvious that, in another variant not shown in which the arming of the automaton barrel is made by the drum in order to rotate the barrel in the opposite direction, the first driving pinion will then be arranged to mesh with the drum of said barrel.

Dans l'exemple décrit ici, les premier et second accumulateurs d'énergie 26, 27 sont remontés par leur rochet respectif, des mécanismes anti-retour (non représentés) tels que cliquet, ressort ou sautoir, connus de l'homme du métier, étant prévus au niveau du rochet pour empêcher le rochet de revenir en arrière.In the example described here, the first and second energy accumulators 26, 27 are raised by their respective ratchet, anti-return mechanisms (not shown) such as ratchet, spring or jumper, known to those skilled in the art, being provided at the ratchet to prevent the ratchet from going back.

Ladite seconde bascule d'embrayage 36 est montée libre sur l'axe de la seconde roue de couronne 34 et le second pignon entraineur 38 est monté à friction sur ladite seconde bascule d'embrayage 36, de sorte que, tant que le second dispositif d'embrayage 18 n'occupe pas sa position d'embrayage, ladite seconde bascule d'embrayage 36 et le second pignon entraineur 38 pivotent solidairement avec ladite seconde roue de couronne 34 pour passer :

  • en position d'embrayage et lier cinématiquement le second pignon entraineur 38 au second rochet 40 du second accumulateur d'énergie 27 puis, une fois le second pignon entraineur 38 au contact du second rochet 40 du second accumulateur d'énergie 27, la seconde bascule d'embrayage 36 est empêchée de continuer à pivoter et le second pignon entraineur 38 se désolidarise de la seconde bascule d'embrayage 36 grâce à la friction, permettant ainsi l'entrainement du second pignon entraineur 38 par le pignon de remontoir 4 via le pignon de remontoir intermédiaire 32 et la seconde roue de couronne 34 pour remonter le second accumulateur d'énergie 27 lorsque la tige de remontoir 2 est tournée dans le second sens, à savoir ici le sens antihoraire,
  • en position de débrayage en éloignant le second pignon entraineur 38 du second accumulateur d'énergie 27 lorsque la tige de remontoir 2 est tournée dans le premier sens, à savoir ici le sens horaire.
Said second clutch lever 36 is mounted free on the axis of the second crown wheel 34 and the second driving pinion 38 is frictionally mounted on said second clutch lever 36, so that as long as the second clutch lever 36 clutch 18 does not occupy its clutch position, said second clutch lever 36 and the second gear coach 38 pivot jointly with said second crown wheel 34 to pass:
  • in the clutch position and kinematically link the second driving gear 38 to the second ratchet 40 of the second energy accumulator 27, and then, once the second driving pinion 38 is in contact with the second ratchet 40 of the second energy accumulator 27, the second latch the clutch 36 is prevented from continuing to pivot and the second driving pinion 38 disengages from the second clutch lever 36 by virtue of the friction, thus enabling the second driving pinion 38 to be driven by the winding pinion 4 via the pinion intermediate winding device 32 and the second crown wheel 34 to refit the second energy accumulator 27 when the winding stem 2 is turned in the second direction, namely here the counterclockwise direction,
  • in the disengaged position by moving the second drive pinion 38 away from the second energy accumulator 27 when the winding stem 2 is turned in the first direction, namely here the clockwise direction.

Il est bien évident que les sens de rotation de la tige de remontoir décrits ici ne sont pas limitatifs et qu'ils peuvent être inversés, le premier accumulateur d'énergie pouvant être remonté par rotation de la tige de remontoir dans le sens antihoraire, le second accumulateur d'énergie étant alors remonté par rotation de la tige de remontoir dans le sens horaire.It is obvious that the directions of rotation of the winding stem described here are not limiting and that they can be reversed, the first energy accumulator can be raised by rotation of the winding stem in the counterclockwise direction. second energy accumulator is then raised by rotation of the winding stem in the clockwise direction.

De plus, il est à noter que l'utilisation d'un pignon de remontoir intermédiaire est facultative et sera à adapter par l'homme du métier en fonction par exemple du positionnement et du sens de rotation des autres composants de la construction, et notamment par exemple en fonction des sens de rotation des barillets. Si les barillets doivent avoir des sens de fonctionnement opposés, l'homme du métier sait comment agencer leurs composants (tambour, ressort, arbre) en conséquence.In addition, it should be noted that the use of an intermediate winding gear is optional and will be adapted by the skilled person depending eg on the positioning and direction of rotation of the other components of the construction, including for example depending on the direction of rotation of the barrels. If the barrels must have opposite operating directions, the skilled person knows how to arrange their components (drum, spring, shaft) accordingly.

Le fonctionnement du mécanisme de remontage selon l'invention est le suivant : en référence aux figures 5 à 7, lorsqu'il est nécessaire de remonter le barillet de mouvement, la tige de remontoir 2 est positionnée dans sa position axiale de remontage pour que le pignon coulant 6 engrène avec le pignon de remontoir 4 comme le montre la figure 13, puis la tige de remontoir 2 est tournée dans le sens horaire. Cette rotation de la tige de remontoir 2 entraine la rotation du pignon de remontoir 4 dans le sens horaire. Côté mouvement, le pignon de remontoir 4 engrène avec la première roue de couronne 20 pour la faire pivoter dans le sens antihoraire. La première bascule d'embrayage 22 et le premier pignon entraineur 24 étant solidaires du fait de la friction et de l'absence de transmission de couple à travers les rouages, et le premier pignon entraineur 24 étant en prise avec la première roue de couronne 20, la première bascule d'embrayage 22 et le premier pignon entraineur 24 pivotent solidairement avec ladite première roue de couronne 20 autour de son axe dans le sens antihoraire jusqu'à ce que le premier pignon entraineur 24 entre en contact avec le premier rochet 28. Le premier dispositif d'embrayage/débrayage 16 est en position d'embrayage, comme le montrent les figures 5 et 7. Le pivotement de la première bascule d'embrayage 22 étant désormais empêché, le premier pignon entraineur 24 se désolidarise alors de la première bascule d'embrayage 22 grâce à la friction, de sorte que la rotation de la première roue de couronne 20 entrainée par le pignon de remontoir 4 entraine maintenant la rotation du premier pignon entraineur 24 qui engrène avec le premier rochet 28 pour le remontage du barillet de mouvement.The operation of the winding mechanism according to the invention is as follows: with reference to Figures 5 to 7 when it is necessary to winding the movement barrel, the winding stem 2 is positioned in its axial winding position so that the sliding pinion 6 meshes with the winding pinion 4 as shown in FIG. figure 13 then the winding stem 2 is turned clockwise. This rotation of the winding stem 2 causes the rotation of the winding pinion 4 in the clockwise direction. Movement side, the winding pinion 4 meshes with the first crown wheel 20 to rotate it counterclockwise. The first clutch lever 22 and the first drive pinion 24 being integral due to the friction and the absence of torque transmission through the gear trains, and the first drive pinion 24 being engaged with the first ring gear 20 , the first clutch rocker 22 and the first driving pinion 24 pivot integrally with said first crown wheel 20 about its axis counterclockwise until the first driving pinion 24 comes into contact with the first ratchet 28. The first clutch / clutch device 16 is in the clutch position, as shown by the Figures 5 and 7 . The pivoting of the first clutch rocker 22 is now prevented, the first driving pinion 24 then disengages from the first clutch rocker 22 thanks to the friction, so that the rotation of the first crown wheel 20 driven by the winding pinion 4 now causes the rotation of the first drive pinion 24 which meshes with the first ratchet 28 for the winding of the movement barrel.

En parallèle, côté planche ou côté automate, la rotation du pignon de remontoir 4 dans le sens horaire entraine la rotation du pignon de remontoir intermédiaire 32 dans le sens antihoraire. Cette rotation du pignon de remontoir intermédiaire 32 entraine la rotation de la seconde roue de couronne 34 dans le sens horaire. La deuxième bascule d'embrayage 36 et le second pignon entraineur 38 étant solidaires du fait de la friction et de l'absence de transmission de couple à travers les rouages, et le second pignon entraineur 38 étant en prise avec la seconde roue de couronne 34, la seconde bascule d'embrayage 36 et le second pignon entraineur 38 pivotent solidairement avec ladite seconde roue de couronne 34 autour de son axe dans le sens horaire pour écarter ledit second pignon entraineur 38 du second accumulateur d'énergie 27 comme le montrent les figures 5 et 6. Le second dispositif d'embrayage/débrayage 18 est alors en position de débrayage de sorte que le second accumulateur d'énergie 27 n'est pas remonté pendant le remontage du premier accumulateur d'énergie 26 par rotation de la tige de remontoir 2 dans le sens horaire.In parallel, board side or PLC side, the rotation of the winding pinion 4 in the clockwise direction causes the rotation of the intermediate winding pinion 32 in the counterclockwise direction. This rotation of the intermediate winding pinion 32 causes the rotation of the second crown wheel 34 in the clockwise direction. The second clutch lever 36 and the second drive pinion 38 being integral due to the friction and the absence of torque transmission through the gear trains, and the second drive pinion 38 being engaged with the second ring gear 34 , the second clutch lever 36 and the second drive pinion 38 pivot integrally with said second crown gear 34 about its axis in a clockwise direction to move said second drive gear 38 away from the second energy accumulator 27 as shown by the Figures 5 and 6 . The second clutch / clutch device 18 is then in the disengaged position so that the second energy accumulator 27 is not raised during the reassembly of the first energy accumulator 26 by rotation of the winding stem 2 in the clockwise.

Pour remonter le second accumulateur d'énergie, ici le barillet d'automate, en référence aux figures 8 à 10, la tige de remontoir 2 est toujours positionnée dans sa position axiale de remontage pour que le pignon coulant 6, qui ne s'est pas déplacé, engrène toujours avec le pignon de remontoir 4 comme le montre la figure 13, puis la tige de remontoir 2 est tournée dans le sens antihoraire. Cette rotation de la tige de remontoir 2 entraine la rotation du pignon de remontoir 4 dans le sens antihoraire. Côté planche ou automate, la rotation du pignon de remontoir 4 dans le sens antihoraire entraine la rotation du pignon de remontoir intermédiaire 32 dans le sens horaire. Cette rotation du pignon de remontoir intermédiaire 32 entraine la rotation de la seconde roue de couronne 34 dans le sens antihoraire. La deuxième bascule d'embrayage 36 et le second pignon entraineur 38 étant solidaires du fait de la friction et de l'absence de transmission de couple à travers les rouages, et le second pignon entraineur 38 étant en prise avec la seconde roue de couronne 34, la seconde bascule d'embrayage 36 et le second pignon entraineur 38 pivotent solidairement avec ladite seconde roue de couronne 34 autour de son axe dans le sens antihoraire jusqu'à ce que le second pignon entraineur 38 entre en contact avec le second rochet 40. Le second dispositif d'embrayage/débrayage 18 est en position d'embrayage comme le montrent les figures 8 et 9. Le pivotement de la seconde bascule d'embrayage 36 étant désormais empêché, le second pignon entraineur 38 se désolidarise alors de la seconde bascule d'embrayage 36 grâce à la friction, de sorte que la rotation de la seconde roue de couronne 34 entrainée par le pignon de remontoir 4 et le pignon de remontoir intermédiaire 32 entraine maintenant la rotation du second pignon entraineur 38 qui engrène avec le second rochet 40 pour le remontage du barillet d'automate.To reassemble the second energy accumulator, here the automaton barrel, with reference to Figures 8 to 10 , the winding stem 2 is always positioned in its axial winding position so that the sliding pinion 6, which has not moved, always meshes with the winding pinion 4 as shown in FIG. figure 13 , then the winding stem 2 is rotated counterclockwise. This rotation of the winding stem 2 causes the rotation of the winding pinion 4 counterclockwise. Side plank or automaton, the rotation of the winding pinion 4 counterclockwise causes the rotation of the intermediate winding pinion 32 in the clockwise direction. This rotation of the intermediate winding pinion 32 causes the rotation of the second crown wheel 34 counterclockwise. The second clutch lever 36 and the second drive pinion 38 being integral due to the friction and the absence of torque transmission through the gear trains, and the second drive pinion 38 being engaged with the second ring gear 34 the second clutch lever 36 and the second drive gear 38 pivot integrally with said second ring gear 34 about its axis counterclockwise until the second drive gear 38 comes into contact with the second ratchet 40. The second clutch / clutch device 18 is in the clutch position as shown by the Figures 8 and 9 . Since the pivoting of the second clutch lever 36 is now prevented, the second drive pinion 38 then disengages from the second clutch lever 36 thanks to the friction, so that the rotation of the second ring gear 34 driven by the winding pinion 4 and the intermediate winding pinion 32 now causes the rotation of the second drive pinion 38 which meshes with the second ratchet 40 for the winding of the automaton barrel.

En parallèle, côté mouvement, le pignon de remontoir 4 tournant dans le sens antihoraire engrène avec la première roue de couronne 20 pour la faire pivoter dans le sens horaire. La première bascule d'embrayage 22 et le premier pignon entraineur 24 étant solidaires du fait de la friction et de l'absence de transmission de couple à travers les rouages, et le premier pignon entraineur 24 étant en prise avec la première roue de couronne 20, la première bascule d'embrayage 22 et le premier pignon entraineur 24 pivotent solidairement avec ladite première roue de couronne 20 autour de son axe dans le sens horaire pour écarter ledit premier pignon entraineur 24 du premier accumulateur d'énergie 26 comme le montrent les figures 8 et 10. Le premier dispositif d'embrayage/débrayage 16 est alors en position de débrayage de sorte que le premier accumulateur d'énergie 26 n'est pas remonté pendant le remontage du second accumulateur d'énergie 27 par rotation de la tige de remontoir 2 dans le sens antihoraire.In parallel, on the movement side, the winding pinion 4 rotating counterclockwise meshes with the first crown wheel 20 to rotate it clockwise. The first clutch lever 22 and the first drive pinion 24 being integral due to the friction and the absence of torque transmission through the gear trains, and the first drive pinion 24 being engaged with the first ring gear 20 the first clutch lever 22 and the first drive gear 24 pivot integrally with said first ring gear 20 about its axis in a clockwise direction to move said first drive gear 24 away from the first energy accumulator 26 as shown by FIGS. Figures 8 and 10 . The first clutch / clutch device 16 is then in the disengaged position so that the first energy accumulator 26 is not raised during reassembly of the second energy accumulator 27 by rotation of the winding stem 2 in the anticlockwise.

Ainsi, le mécanisme de remontage selon l'invention permet un remontage précis et fiable de deux accumulateurs d'énergie par la seule rotation de la tige de remontoir dans les deux sens, la tige de remontoir occupant une même position axiale de remontage.Thus, the winding mechanism according to the invention allows a precise and reliable reassembly of two energy accumulators by the single rotation of the winding stem in both directions, the winding stem occupying the same axial position of winding.
