Description

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne, plus particulièrement, les mécanismes indicateurs de réserve de marche pour mouvement de pièce d'horlogerie du type muni d'une source d'énergie formée d'un ressort-moteur. De manière classique, le mécanisme selon l'invention comporte un bâti, un indicateur de réserve de marche et un engrenage différentiel avec une première entrée reliée à un mobile entraíné en rotation lors de l'armage du ressort-moteur et une deuxième entrée reliée à un mobile entraíné en rotation lors du désarmage du ressort-moteur, et une sortie reliée à l'indicateur de réserve de marche. Dans un tel mécanisme, l'indicateur est susceptible de parcourir un angle donné compris entre deux positions extrêmes dont la première est occupée lorsque le ressort-moteur est armé et la seconde, lorsque le ressort est désarmé.The present invention relates to the field of watchmaking. It concerns more particularly, the power reserve indicator mechanisms for timepiece movement of the type provided with a formed energy source of a motor spring. In a conventional manner, the mechanism according to the invention includes a frame, a power reserve indicator and a gear differential with a first input connected to a mobile driven in rotation during the winding of the mainspring and a second input connected to a mobile rotated during the disarming of the mainspring, and an output connected to the power reserve indicator. In such a mechanism, the indicator is likely to traverse a given angle between two extreme positions the first of which is occupied when the mainspring is armed and the second, when the spring is disarmed.

Un mécanisme de ce type est décrit dans "La montre suisse à remontage automatique" de B. Humbert, éditions Scriptar, Lausanne 1955, en page 85. Il est muni d'un indicateur monté à friction sur un mobile relié à la sortie du différentiel. Les deux positions extrêmes entre lesquelles l'indicateur se déplace sont définies par des butées. Lorsque l'indicateur arrive à l'une des butées, de la limite supérieure d'armage ou de désarmage du ressort-moteur, il reste immobile tandis que le ressort-moteur continue à être armé ou à se désarmer, la friction permettant le déplacement du rouage alors que l'indicateur est fixe.A mechanism of this type is described in "The Swiss watch with winding automatic "by B. Humbert, editions Scriptar, Lausanne 1955, on page 85. is equipped with a friction mounted indicator on a mobile connected to the output of the differential. The two extreme positions between which the indicator moves are defined by stops. When the indicator arrives at one of the stops, the upper limit for winding or disarming the mainspring, it remains stationary while the mainspring continues to be armed or disarmed, the friction allowing the wheel to move while the indicator is fixed.

Une telle solution permet donc d'estimer l'armage réel du ressort-moteur, mais il peut y avoir des différences importantes d'un cycle à l'autre, dû au déplacement relatif de l'indicateur par rapport au rouage.Such a solution therefore makes it possible to estimate the actual winding of the mainspring, but There may be significant differences from cycle to cycle due to displacement relative to the gear train.

Pour pallier cet inconvénient, la demande de brevet EP 1 139 182 déposée au nom de la demanderesse décrit un mécanisme comprenant un mobile intermédiaire intercalé entre la sortie de l'engrenage différentiel et l'indicateur de réserve de marche. Ce mobile comporte un élément élastique agencé de manière à ce que l'engrenage différentiel continue à tourner librement alors que l'indicateur reste en butée, entraínant l'armage de l'élément élastique.To overcome this drawback, patent application EP 1 139 182 filed at Applicant's name describes a mechanism including a mobile intermediate between the output of the differential gear and the indicator of power reserve. This mobile comprises an elastic element arranged so that the differential gear continues to rotate freely while the indicator remains in abutment, causing the arming of the elastic element.

Pratiquement, cette disposition est utilisable lorsque l'indicateur est en butée dans l'une ou l'autre de ses positions extrêmes. Mais il est difficile de faire parfaitement coïncider la position d'armage maximum du ressort-moteur avec la position extrême de l'indicateur correspondant à la plus grande réserve de marche. Cela implique des précautions particulières et des mesures précises lors de l'assemblage, notamment lors du service après-vente, pour que l'indicateur affiche une information correcte.In practice, this arrangement is usable when the indicator is in abutment in one or the other of its extreme positions. But it's hard to do perfectly match the maximum winding position of the mainspring with the extreme position of the indicator corresponding to the largest reserve of walk. This implies special precautions and precise measurements when of assembly, particularly during after-sales service, so that the indicator displays correct information.

La présente invention a pour but de pallier l'inconvénient évoqué ci-dessus, tout en conservant les avantages présentés par le mécanisme de la demande EP déjà citée.The present invention aims to overcome the drawback mentioned above, while retaining the benefits of the EP application mechanism already mentioned.

De façon plus précise, l'invention concerne un mécanisme indicateur de réserve de marche pour mouvement de pièce d'horlogerie du type comportant un bâti, une source d'énergie formée d'un barillet et d'un ressort-moteur logé dans le barillet, un rouage de finissage entraíné par le barillet et des moyens d'armage du ressort-moteur. Ce mécanisme comprend :

  • un indicateur de réserve de marche avec un mobile et un dispositif d'affichage porté par le mobile,
  • un engrenage différentiel relié cinématiquement par une première entrée au barillet, par une seconde entrée aux moyens d'armage et par une sortie à l'indicateur, et
  • un mobile intermédiaire comportant des première et deuxième parties respectivement reliées cinématiquement à la sortie et au mobile de l'indicateur et un organe de liaison reliant ces parties, agencé de manière à ce que l'indicateur occupe une position comprise entre deux positions extrêmes, la première atteinte lorsque l'armage du ressort est plus fort qu'une valeur limite supérieure, et la deuxième lorsque l'armage du ressort est plus faible qu'une valeur limite inférieure, les première et deuxième parties tournant conjointement tant que l'armage du ressort est compris entre ses valeurs extrêmes.
More specifically, the invention relates to a power reserve indicator mechanism for a timepiece movement of the type comprising a frame, a power source formed of a barrel and a mainspring housed in the barrel. , a work train driven by the barrel and winding means of the mainspring. This mechanism includes:
  • a power reserve indicator with a mobile and a display device carried by the mobile,
  • a differential gear kinematically connected by a first input to the barrel, a second input to the winding means and an output to the indicator, and
  • an intermediate mobile having first and second parts respectively kinematically connected to the output and the mobile of the indicator and a connecting member connecting these parts, arranged so that the indicator occupies a position between two extreme positions, the first when the armature of the spring is stronger than an upper limit value, and the second when the armature of the spring is lower than a lower limit value, the first and second parts rotating together as long as the arming of the spring is between its extreme values.

Selon l'invention, l'organe de liaison comprend un mécanisme à friction agencé de manière à ce que la première partie puisse se mouvoir à friction en référence à la deuxième lorsque l'indicateur a atteint sa première position extrême, et un élément élastique agencé de manière à pouvoir être armé lorsque l'indicateur a atteint sa seconde position extrême, par le déplacement de la première partie en référence à la deuxième partie.According to the invention, the connecting member comprises an arranged friction mechanism so that the first part can move frictionally with reference at the second when the indicator has reached its first extreme position, and a elastic element arranged so that it can be armed when the indicator has reaches its second extreme position, by moving the first part reference to the second part.

Avantageusement, le mécanisme à friction comporte une butée solidaire de l'une des parties et un levier monté à friction sur l'autre partie, disposé et dimensionné de manière à ce que :

  • lorsque l'indicateur occupe sa première position extrême et que l'armage du ressort-moteur se poursuit, le levier est maintenu contre la butée et tourne à friction sur la partie dont il est solidaire, de telle sorte que l'indicateur reste immobile, et
  • dès que le ressort-moteur se désarme, l'indicateur quitte sa première position extrême, les première et deuxième parties du mobile intermédiaire tournant ensemble.
Advantageously, the friction mechanism comprises an abutment integral with one of the parts and a lever frictionally mounted on the other part, arranged and dimensioned so that:
  • when the indicator occupies its first extreme position and the winding of the mainspring continues, the lever is held against the stop and rotates with friction on the part of which it is secured, so that the indicator remains stationary, and
  • as soon as the mainspring disarms, the indicator leaves its first extreme position, the first and second parts of the intermediate mobile rotating together.

Le levier est doté d'une fente longitudinale s'élargissant en une ouverture engagée sur le pignon.The lever has a longitudinal slot widening into an opening engaged on the pinion.

L'élément élastique est solidaire de la partie comportant la butée et coopère avec le levier de manière à ce que, lorsque l'indicateur occupe sa deuxième position extrême, il est immobilisé, alors que le ressort-moteur entraíne le rouage de finissage et l'engrenage différentiel, et que l'élément élastique s'arme, puis se désarme lors de l'armage du ressort-moteur.The elastic element is integral with the part comprising the abutment and cooperates with the lever so that when the indicator occupies its second position extreme, it is immobilized, while the mainspring causes the wheel of finishing and the differential gear, and that the elastic element is armed, then disarming when winding the mainspring.

Le mécanisme comporte encore un différentiel 18 décrit en détail dans la demande EP susmentionnée. En résumé, il comprend un arbre 20 placé à sa sortie, un porte-satellite 22 solidaire en rotation de l'arbre 20 et portant un satellite 24 à denture conique. Une première et une deuxième entrées sont respectivement constituées d'une première 26 et d'une deuxième 28 roues montées librement sur le porte-satellite 22.The mechanism further comprises a differential 18 described in detail in the EP application mentioned above. In summary, it includes a tree 20 placed at its output, a satellite carrier 22 integral in rotation with the shaft 20 and carrying a satellite 24 with conical teeth. First and second entries are respectively constituted of a first 26 and a second 28 wheels mounted freely on the carrier 22.

Les roues 26 et 28 sont formées chacune par une planche identifiée par la lettre a et dont la périphérie porte une denture b, et un pignon c muni d'une denture conique d. La roue 26 engrène, par sa denture 26b, avec le barillet 10. La roue 28 engrène, par sa denture 28b, avec un renvoi 30, engrenant lui-même avec la roue à rochet 16.

Le mobile 32 comprend encore une roue 36 formée d'une planche 36a dont la périphérie est munie d'une denture 36b qui engrène avec l'arbre 20 du différentiel 18. Une entretoise 37 est chassée sur la portion 34c du manchon 34a. La roue 36 est montée libre en rotation sur l'entretoise 37 et peut, ainsi, tourner sur le pignon 34.The mobile 32 further comprises a wheel 36 formed of a board 36a whose periphery is provided with a toothing 36b which meshes with the shaft 20 of the differential 18. A spacer 37 is driven on the portion 34c of the sleeve 34a. The wheel 36 is mounted free to rotate on the spacer 37 and can, thus, turn on the pinion 34.

Le levier 38 présente ainsi, de part et d'autre de l'ouverture 42, un grand bras 38a et un petit bras 38b. Il est clipsé sur la partie conique 34d du pignon 34 de manière à assurer le maintien axial de la roue 36. Le pignon 34 et le levier 38 forment ainsi un mécanisme à friction, dont le couple limite est défini par l'élasticité des bras 38a et 38b.Particularly to the invention, a lever 38 of rectangular shape and whose length is about 0.75 times that of the diameter of the wheel 36, is provided with a longitudinal slot 41 widening into an opening 42 located approximately two-thirds of its length. The lever 38 thus presents, both sides of the opening 42, a large arm 38a and a small arm 38b. It is clipped on the conical portion 34d of the pinion 34 so as to ensure the maintenance axial wheel 36. The pinion 34 and the lever 38 thus form a mechanism to friction, whose limit torque is defined by the elasticity of the arms 38a and 38b.

Par ailleurs, un ressort 40 formé d'une lame élastique en arc de cercle embrassant un angle d'environ 270° est fixé, par l'une de ses extrémités 44 et de manière connue, à la planche de la roue 36. Son autre extrémité 46, libre, forme un coude 46a replié vers l'extérieur de la roue et disposé de manière à ce que, au repos, il soit en appui contre le grand bras 38a, à proximité de l'ouverture 42 et maintient ainsi le levier en appui contre l'extrémité 44 de la lame.Furthermore, a spring 40 formed of an elastic blade in a circular arc embracing an angle of about 270 ° is fixed by one of its ends 44 and known manner, the board of the wheel 36. Its other end 46, free form a bend 46a folded towards the outside of the wheel and arranged so that, at rest, it is in support against the large arm 38a, near the opening 42 and thus keeps the lever resting against the end 44 of the blade.

Enfin, la figure 1 montre aussi que le mécanisme comporte un mobile indicateur 48 monté pivotant sur un tigeron 50 chassé dans la platine 8. Il comprend une planche 48a munie, à sa périphérie, d'une denture 48b en prise avec le pignon 34, et un canon 48c s'étendant au-delà de la platine 8 et destiné à porter une aiguille d'indicateur de réserve de marche, non représentée au dessin.Finally, Figure 1 also shows that the mechanism includes a mobile indicator 48 mounted pivoting on a skewer 50 driven into the plate 8. It includes a board 48a provided, at its periphery, with teeth 48b engaged with the pinion 34, and a barrel 48c extending beyond the plate 8 and intended to carry a power reserve indicator needle, not shown in the drawing.

La planche 48a comporte une découpe 48d en forme de secteur annulaire embrassant un angle d'environ 150° correspondant à l'angle de déplacement de l'aiguille. Une goupille 52, chassée dans la platine 8 est engagée dans la découpe 48d et sert de butée au mobile 48, dont une première et une deuxième positions extrêmes sont ainsi définies.The board 48a comprises a cutout 48d in the form of annular sector embracing an angle of about 150 ° corresponding to the angle of displacement of the needle. A pin 52, driven into the plate 8 is engaged in the 48d cut and serves as a stop to the mobile 48, including a first and a second extreme positions are thus defined.

Dans un mouvement de montre muni du mécanisme qui vient d'être décrit, le ressort-moteur 14, en se désarmant, entraíne en rotation et de manière classique le barillet 10 qui engrène avec le rouage de finissage.In a watch movement equipped with the mechanism that has just been described, the motor spring 14, disarming, causes rotation and so the barrel 10 which meshes with the finishing gear.

La demande EP précitée décrit en détail le fonctionnement du différentiel 18 au cours de l'armage et du désarmage du ressort-moteur 14. Il ne sera donc pas repris ici. The aforementioned EP application describes in detail the operation of the differential 18 at during the winding and disarming of the mainspring 14. It will therefore not be resumed here.

En fonctionnement normal, c'est-à-dire lorsque le ressort-moteur est suffisamment armé pour entraíner correctement le rouage de finissage du mouvement et que le mobile indicateur est compris entre ses deux positions extrêmes, alors le ressort 40 entraíne, par son extrémité 44, le levier 38, lequel est enserré entre les extrémités 44 et 46a du ressort 40.In normal operation, that is when the mainspring is sufficiently reinforced to properly train the work train of the movement and that the moving indicator is between its two positions extreme, then the spring 40 causes, by its end 44, the lever 38, which is clamped between the ends 44 and 46a of the spring 40.

Le ressort-moteur 14 se désarme lentement en entraínant le rouage de finissage. Comme on peut le voir sur la figure 4, le couple du ressort-moteur 14, représenté par la courbe 58a, diminue jusqu'à atteindre une valeur limite 60a.The mainspring 14 disarms slowly while driving the wheel of finishing. As can be seen in FIG. 4, the torque of the motor spring 14, represented by the curve 58a, decreases until a limit value 60a is reached.

L'indicateur de réserve de marche indique alors que celle-ci est épuisée et le mobile indicateur est immobilisé, l'extrémité de la découpe 48d étant en appui contre la goupille 52.The power reserve indicator then indicates that it has run out and the mobile indicator is immobilized, the end of the cutout 48d being in support against the pin 52.

A l'instar du mécanisme décrit dans le document EP déjà cité, si l'utilisateur de la montre ne remonte toujours pas le ressort-moteur 14, celui-ci poursuit son désarmage en faisant fonctionner le mouvement de la montre. Le différentiel 18 continue donc à tourner et, avec lui, la roue 36. Comme le pignon 34 engrène avec le mobile indicateur 48, il est bloqué. La roue 36 a donc un mouvement relatif par rapport au pignon 34. Ce mouvement est rendu possible du fait que la roue 36 est reliée au pignon 34 par le ressort 40 qui s'arme. Comme le montre la courbe 62a, le couple engendré par le ressort 40 va croissant du point 64 jusqu'au point 65 où les couples du ressort-moteur 14 et du ressort 40 se compensent, de sorte que la montre s'arrête.Like the mechanism described in the EP document already cited, if the user of the watch does not still raise the mainspring 14, it continues its disarming by operating the movement of the watch. The differential 18 continues to turn and, with him, the wheel 36. As the gear 34 meshes with the mobile indicator 48, it is blocked. The wheel 36 therefore has a movement relative to the pinion 34. This movement is made possible by the fact that the wheel 36 is connected to the pinion 34 by the spring 40 which is armed. As shown in 62a curve, the torque generated by the spring 40 is increasing from point 64 up to point 65 where the torques of the mainspring 14 and the spring 40 compensate, so that the watch stops.

Ensuite, l'utilisateur procède à l'armage du ressort-moteur 14 illustré par la courbe 58b. Le ressort 40 se désarme (courbe 62b) puis, lorsque le levier 38 retrouve sa position de repos, le couple du ressort-moteur atteint une certaine valeur au point 60b, le mobile indicateur est à nouveau entraíné et l'indicateur se déplace en regard de l'échelle du cadran. Durant cette opération d'armage du ressort-moteur, l'extrémité 44 du ressort 40 entraíne le levier 38 avec un couple inférieur au couple de friction du levier sur le pignon et entraíne donc, avec lui, le pignon 34. Puis, lorsque l'indicateur de réserve de marche affiche la charge maximum, le mobile indicateur est immobilisé. Le couple du ressort-moteur 14 correspondant est représenté au point 66 de la courbe 58b. Le pignon 34 est alors bloqué puisqu'il engrène avec le mobile indicateur.Then, the user proceeds to wind the motor spring 14 illustrated by the curve 58b. The spring 40 disarms (curve 62b) then, when the lever 38 rest position, the torque of the motor spring reaches a certain value in point 60b, the mobile indicator is again driven and the indicator is moves next to the scale of the dial. During this arming operation motor spring, the end 44 of the spring 40 drives the lever 38 with a couple less than the friction torque of the lever on the pinion and therefore drives, with him, the 34. Then, when the power reserve indicator shows the load maximum, the mobile indicator is immobilized. The torque of the mainspring 14 corresponding is shown in point 66 of curve 58b. Pinion 34 is then blocked because it meshes with the mobile indicator.

Si l'utilisateur de la montre continue à armer le ressort-moteur 14, il doit alors vaincre la friction du levier 38 sur le manchon 34a, ce qui est illustré par la portion 68 de la courbe 58b. Le levier 38, en buté sur l'extrémité 44 du ressort 40, pivote donc sur le pignon 34 jusqu'à l'armage maximal du ressort-moteur 14. Grâce au système à bride glissante, le couple de ce dernier est stabilisé au niveau du plateau 70, malgré la poursuite de l'armage. On obtient ainsi un parfait calage des différents éléments du mécanisme de l'indicateur et une correspondance entre les positions extrêmes du levier et de l'indicateur et l'armage maximal du ressort-moteur, sans devoir prendre de mesure particulière lors de la mise en place des constituants de ce mécanisme.If the user of the watch continues to arm the mainspring 14, he must then overcome the friction of the lever 38 on the sleeve 34a, which is illustrated by the portion 68 of curve 58b. The lever 38, abutting on the end 44 of the spring 40, pivots on the pinion 34 to the maximum armature of the mainspring 14. Thanks to the sliding flange system, the torque of the latter is stabilized at level of the plateau 70, despite the continuation of the arming. We thus obtain a perfect calibration of the different elements of the indicator mechanism and a correspondence between the extreme positions of the lever and the indicator and the maximum winding of the mainspring, without having to take any particular action during the establishment of the constituents of this mechanism.

Le cycle suivant de désarmage se déroule comme décrit ci-dessus. Puis, lors du réarmage suivant, grâce au calage réalisé lors du premier cycle, l'utilisateur sait que lorsque l'indicateur atteint sa position extrême, le ressort-moteur est complètement armé.The next disarming cycle proceeds as described above. Then, during the next reset, thanks to the calibration performed during the first cycle, the user knows when the indicator reaches its extreme position, the mainspring is completely armed.

Dans le dispositif tel que décrit, la mise en place des différents composants ne nécessite par de mesure particulière, tant au niveau de la production que du service après-vente, l'indicateur se calant automatiquement dans sa position correcte, grâce au fait que, lors de l'armage, le levier 38 tourne à friction sur le pignon 34, alors que, lors du désarmage, le calage est maintenu, du fait que le ressort 40 s'arme. Il est évident que, pour permettre ces dispositions, le couple d'armage du ressort 40 doit toujours rester inférieur au couple de friction du levier 38 sur la portion conique 34d.In the device as described, the implementation of the various components requires special measures, both in terms of production and after-sales service, the indicator automatically settling in its position correct, thanks to the fact that, during the arming, the lever 38 rotates with friction on the pinion 34, while, during disarming, the rigging is maintained, since the spring 40 is armed. It is obvious that, to allow these provisions, the couple armature of the spring 40 must always remain lower than the friction torque of the lever 38 on the taper portion 34d.
