Description

Domaine de l'inventionField of the invention

L'invention concerne un mouvement mécanique d'horlogerie comprenant un mécanisme de sonnerie et plus particulièrement un tel mouvement comprenant un dispositif permettant de limiter le jeu angulaire dans le rouage de minuterie.The invention relates to a clockwork mechanical movement comprising a striking mechanism and more particularly such a movement comprising a device for limiting the angular play in the clockwork.

L'invention concerne encore une pièce d'horlogerie notamment une montre bracelet à sonnerie comportant un tel mouvement.The invention also relates to a timepiece including a bell-shaped wristwatch comprising such a movement.

Arrière-plan de l'inventionBackground of the invention

Les mécanismes de sonnerie d'horlogerie sont de grandes complications, complexes autant par le nombre et la complexité des cinématiques de leurs composants, que selon les modes de fonctionnement dont ils sont capables.Watchmaking mechanisms are great complications, complex as much by the number and complexity of the kinematics of their components, as by the modes of operation of which they are capable.

Dans les mécanismes de sonnerie notamment les mécanismes de sonnerie à répétitions classiques, le limaçon des minutes, c'est-à-dire la came portant les entailles pour régler la sonnerie des minutes qui coopère avec le palpeur de la pièce des minutes, est directement fixé sur la chaussée qui porte à son extrémité l'aiguille des minutes. Un tel arrangement garantit un mécanisme sans décalage entre la position de l'aiguille des minutes en regard de l'échelle des minutes du cadran et le nombre de coups des minutes sonnés.In the ringing mechanisms including conventional repetition ring mechanisms, the minutes snail, that is to say the cam bearing the notches to set the minute ringer that cooperates with the probe of the minute room, is directly fixed on the roadway which carries at its end the minute hand. Such an arrangement ensures a mechanism with no offset between the position of the minute hand opposite the minute scale of the dial and the number of minutes strokes sounded.

Lorsque pour des raisons esthétiques ou autres on souhaite décaler axialement la disposition des aiguilles des heures et des minutes par rapport au limaçon des minutes porté classiquement par la chaussée principale, on prévoit une chaussée secondaire reliée à la chaussée principale par l'intermédiaire d'un renvoi ou avantageusement de la minuterie du mouvement. Dans une telle configuration, la correspondance entre la position du limaçon des minutes porté par la chaussée principale et la position de l'aiguille des minutes portée par la chaussée secondaire, en regard de l'échelle des minutes est dépendante de la somme des jeux angulaires dans le rouage de minuterie. Or, ce jeu angulaire total entre la chaussée secondaire et la chaussée principale portant de limaçon des minutes est typiquement de l'ordre de 3 à 8°. Sachant qu'un arc de 6° représente une minute d'erreur de lecture sur l'échelle des minutes du cadran, il est des circonstances dans lesquelles la position de l'aiguille des minutes en regard de l'échelle des minutes du cadran et le nombre de coups des minutes sonnés est incorrecte. Cette situation est bien entendu inacceptable pour des produits de luxe et de haute qualité que sont les pièces d'horlogerie équipées de mouvements d'horlogerie à mécanisme de sonnerie à répétition minutes ou grandes sonnerie.When, for aesthetic or other reasons, it is desired to axially shift the arrangement of the hour and minute hands relative to the minute neck carried conventionally by the main roadway, a secondary roadway is provided connected to the main roadway via a roadway. return or advantageously from the timer of the movement. In such a configuration, the correspondence between the position of the minute limb carried by the main roadway and the position of the minute hand carried by the secondary roadway, opposite the minute scale is dependent on the sum of the angular gaps in the clockwork. However, this total angular clearance between the secondary roadway and the main road bearing minutes snail is typically of the order of 3 to 8 °. Knowing that an arc of 6 ° represents a minute of reading error on the minute scale of the dial, there are circumstances in which the position of the minute hand opposite the minute scale of the dial and the number of strokes of the minutes sounded is incorrect. This situation is of course unacceptable for luxury and high quality products that are timepieces equipped with watch movements with a minute or large ringing mechanism.

Résumé de l'inventionSummary of the invention

L'invention a donc pour but principal de fournir un mouvement d'horlogerie à mécanisme de sonnerie notamment à répétition minutes visant à pallier les inconvénients de l'art antérieur et en particulier de fournir un tel mouvement visant à réduire voire supprimer le jeu angulaire dans le rouage s'étendant entre la chaussée principale et la chaussée secondaire afin d'assurer une concordance parfaite entre la position de l'aiguille des minutes en regard de l'échelle des minutes du cadran et le nombre de coups des minutes sonnés.The main purpose of the invention is therefore to provide a clockwork movement with a particularly minute-repeating mechanism intended to overcome the drawbacks of the prior art and in particular to provide such a movement aimed at reducing or even eliminating the angular clearance in the train running between the main road and the secondary road to ensure a perfect match between the position of the minute hand opposite the minute scale of the dial and the number of minutes strokes sounded.

L'invention a également pour but de fournir un tel mouvement d'horlogerie qui soit peu encombrant, économique et simple à mettre en oeuvre.The invention also aims to provide such a watch movement that is compact, economical and simple to implement.

L'invention a également pour but de fournir un dispositif réglable par l'horloger, réglage qui permet de compenser les défauts de tolérances des dimensions des composants souvent importants dans ces mécanismes très compliqués et fabriqués en petites séries.The invention also aims to provide a device adjustable by the watchmaker, adjustment that compensates for tolerances defects dimensions of often important components in these very complicated mechanisms and manufactured in small series.

Ce faisant, l'horloger peut donc aisément ajuster la distance entre l'axe de la roue de minuterie et les axes respectifs des première et deuxième chaussées et ainsi régler la profondeur de pénétration des dents de la roue de minuterie dans la denture des pignons respectifs des première et deuxième chaussées" ajustant par là même le jeu angulaire dans le rouage et donc assurant une concordance parfaite entre la position de l'aiguille des minutes en regard de l'échelle des minutes du cadran et la position du limaçon des minutes lors de la prise d'information par le palpeur de la pièce des minutes et donc le nombre coups sonnés.With this device, by acting on the angular position of the rocker carrying the timer wheel, the watchmaker has a simple adjustment device of the angular clearance in the gear train in the train extending between the first floor and the door. second floor. In doing so, the watchmaker can easily adjust the distance between the axis of the timer wheel and the respective axes of the first and second roadways and thus adjust the depth of penetration of the teeth of the timer wheel into the teeth of the respective gears. first and second pavements "thereby adjusting the angular clearance in the train and thus ensuring a perfect match between the position of the minute hand opposite the minute scale of the dial and the position of the minutes snail when the information taken by the probe of the minute room and therefore the number of shots sounded.

A la figure 1 on voit un mouvement d'horlogerie 1 destiné à être intégré dans une pièce d'horlogerie, par exemple, du type montre bracelet. Le mouvement d'horlogerie 1 comporte au moins un mécanisme de sonnerie 2 dont seuls les éléments nécessaires à la compréhension de l'invention ont été représentés.To the figure 1 we see a watch movement 1 intended to be integrated into a timepiece, for example, the wristwatch type. The watchmaking movement 1 comprises at least one striking mechanism 2 of which only the elements necessary for the understanding of the invention have been represented.

L'homme de métier pourra se référer à l'ouvrage de François LECOULTRE « Les montres compliquées », Editions horlogères, Bienne (Suisse), 1985, ISBN 2-88175-000-1 , qui expose de façon détaillée les mécanismes de base constitutifs des mécanismes de sonnerie, aux pages 97 à 205, sous différents chapitres :

  • sonneries,

  • ancient repetition,
  • modern quarter rehearsal,
  • simplified repetition,
  • half-quarter repetition,
  • half-quarter Breguet repetition,

Sauf nécessité, ces mécanismes de base ne seront donc pas repris ici en détail, le spécialiste des sonneries saura en retrouver la constitution dans cet ouvrage de référence universel, dans les chapitres cités ci-dessus qui sont incorporés ici par référence.Unless necessary, these basic mechanisms will not be repeated here in detail, the ringtones specialist will find its constitution in this universal reference in the chapters mentioned above which are incorporated here by reference.

Le mouvement 1 qui est partiellement représenté en perspective comprend classiquement une platine P, un barillet engrenant avec un rouage de finissage en prise avec un échappement (non représentés). Le rouage de finissage est également lié à un rouage de minuterie M qui entraine les aiguilles d'heures 3 et de minutes 4 qui se déplacent au centre d'un cadran 5 surmontant le mouvement 1. En l'occurrence le mouvement est circulaire et le cadran n'est pas centré sur le mouvement.The movement 1 which is partially represented in perspective conventionally comprises a plate P, a barrel meshing with a finishing gear in engagement with an escapement (not shown). The finishing train is also linked to a timer wheel M which drives the hour and minute hands 4 and 4 which move in the center of a dial 5 surmounting the movement 1. In this case the movement is circular and the dial is not centered on the movement.

Le rouage de minuterie comprend classiquement un mobile de minuterie 6 formé d'une roue de minuterie 6a et d'un pignon de minuterie 6b.The timer train typically comprises a timer wheel 6 formed of a timer wheel 6a and a timer gear 6b.

Le mécanisme de sonnerie 2 comporte une première chaussée 7 comprenant un axe 7a portant à une extrémité supérieure un pignon de première chaussée 8 en prise avec une roue de minuterie 6a. L'axe 7a porte également coaxialement et de manière superposée successivement un limaçon des quarts 9, une surprise 10 et un limaçon des minutes 11 qui coopèrent respectivement avec des organes palpeurs (non représentés) du mécanisme de sonnerie 2. Bien entendu dans une variante de réalisation de l'invention, l'axe 7a peut ne comprendre qu'un limaçon. Dans l'exemple illustré, l'axe 7a de la première chaussée porte également dans sa partie médiane un pignon 12 destiné à venir en prise avec un mécanisme de mise à l'heure classique non représenté. Selon une variante, le pignon 12 pourrait être omis et le mécanisme de mise à l'heure pourrait venir en prise directement avec la minuterie M par exemple avec la roue de minuterie 6a. Le pignon de minuterie 6b est en prise avec une roue des heures 13 dont le canon 13a porte l'aiguille des heures 3. La roue de minuterie 6a est également en prise un pignon 14a d'une deuxième chaussée 4 dont le corps 14b s'étend coaxialement à travers le canon 13a et porte l'aiguille des minutes 4. Le pignon 14a de la deuxième chaussée est en outre en prise avec le rouage de finissage qui assure ainsi l'entrainement de la minuterie M qui entraine ainsi indirectement la première chaussée 7.The striking mechanism 2 comprises a first floor 7 comprising an axis 7a carrying at an upper end a first floor pinion 8 in engagement with a timer wheel 6a. The axis 7a also carries coaxially and superimposed successively a quarter snail 9, a surprise 10 and minute snail 11 which cooperate respectively with probing members (not shown) of the striking mechanism 2. Of course in a variant of embodiment of the invention, the axis 7a may comprise only a snail. In the example shown, the axis 7a of the first roadway also carries in its middle part a pinion 12 intended to come into engagement with a conventional time setting mechanism not shown. According to one variant, the pinion 12 could be omitted and the time-setting mechanism could come into direct contact with the timer M, for example with the timer wheel 6a. The timer gear 6b is engaged with a hour wheel 13 whose barrel 13a carries the hour hand 3. The timer wheel 6a is also engaged with a pinion 14a of a second carriageway 4 whose body 14b is extends coaxially through the barrel 13a and carries the minute hand 4. The pinion 14a of the second floor is further engaged with the finishing train which thus ensures the driving of the timer M which thus indirectly leads to the first floor 7.

Comme cela ressort des figures, le mobile de minuterie 6 est monté à pivotement sur une bascule 15 autour d'un axe 16 chassé dans une ouverture ménagée, dans l'exemple illustré dans une partie médiane de la bascule 15. La bascule 15 qui présente une forme générale arquée, est fixée à une première 15a de ses extrémités au moyen d'une vis 17 directement vissée dans un pont Po s'étendant au-dessus de la platine P. La bascule présente dans la zone de la première extrémité 15a un col défini par un rétrécissement R formant une partie flexible pouvant fléchir élastiquement et définissant un axe de flexion FL s'étendant perpendiculairement au plan de la bascule 15. La bascule 15 comprend à sa deuxième extrémité 15b opposée à l'extrémité fixe 15a un logement 15c dans lequel se déplace un organe excentrique 18 qui comprend une tête 18a prolongée par un corps cylindrique 18b prolongé à son tour par un téton 18c excentré par rapport au corps cylindrique 18b. La tête 18a est munie sur sa face supérieure d'une fente 18d pour recevoir l'extrémité d'un outil d'actionnement. Le corps 18b est chassé dans une ouverture correspondante de la bascule 15 et le téton 18c s'étend dans une ouverture oblongue 18e prévue dans le pont Po. La bascule peut donc se déplacer en rotation autour de son axe de flexion FL situé au point le plus étroit du rétrécissement R dans un plan sensiblement parallèle au plan du mouvement 1 selon la flèche F lorsque l'organe excentrique 18 est actionné en rotation. La position angulaire de la bascule 15 peut ainsi être ajustée par l'actionnement en rotation de l'organe excentrique 18 par exemple au moyen d'un tournevis de manière à permettre un réglage simultané de la position la roue de minuterie 6a relativement au pignon 8 de la première chaussée 7 et au pignon 14a de la deuxième chaussée 14. La position de réglage est maintenue par le frottement du corps 18b dans l'ouverture de la bascule 15. On notera en outre que l'élasticité du col permet après le réglage de la position de la bascule de rappeler cette dernière et de diminuer par là même le jeu dans le rouage.As is apparent from the figures, the timer wheel 6 is pivotally mounted on a rocker 15 about an axis 16 driven into a cut-out opening, in the example illustrated in a central portion of the rocker 15. The rocker 15 which presents a generally arcuate shape, is fixed to a first 15a of its ends by means of a screw 17 directly screwed into a bridge Po extending above the plate P. The latch has in the zone of the first end 15a a collar defined by a narrowing R forming a flexible portion resiliently bending and defining a flexion axis FL extending perpendicular to the plane of the rocker 15. The rocker 15 comprises at its second end 15b opposite the fixed end 15a housing 15c in which moves a eccentric member 18 which comprises a head 18a extended by a cylindrical body 18b extended in turn by a pin 18c eccentric relative to the cylindrical body 18b. The head 18a is provided on its upper face with a slot 18d for receiving the end of an actuating tool. The body 18b is driven into a corresponding opening of the rocker 15 and the stud 18c extends in an oblong opening 18e provided in the bridge Po. The rocker can therefore move in rotation around its axis of flexion FL located at the point narrower the narrowing R in a plane substantially parallel to the plane of movement 1 according to the arrow F when the eccentric member 18 is actuated in rotation. The angular position of the rocker 15 can thus be adjusted by the actuation in rotation of the eccentric member 18 for example by means of a screwdriver so as to allow a simultaneous adjustment of the position of the timer wheel 6a relative to the pinion 8 of the first floor 7 and the pinion 14a of the second floor 14. The adjustment position is maintained by the friction of the body 18b in the opening of the rocker 15. It will further be noted that the elasticity of the neck allows after adjustment the position of the rocker to recall the latter and thereby reduce the game in the cog.

Plus précisément, la bascule 15 est agencée relativement au pignon 8 de la première chaussée 7 et relativement au pignon 14a de la deuxième chaussée 14de manière qu'un déplacement angulaire de la bascule 15 autour de l'axe de flexion FL entraine un déplacement circulaire de la bascule 15 qui entraine une pénétration des dents de la roue de minuterie 6a sur une profondeur identique dans la denture du pignon 8 de la première chaussée 7 et dans la denture du pignon 14a de la deuxième chaussée 14.More specifically, the rocker 15 is arranged relative to the pinion 8 of the first roadway 7 and relative to the pinion 14a of the second roadway 14 so that an angular displacement of the rocker 15 about the flexion axis FL causes a circular displacement of the rocker 15 which causes the teeth of the timer wheel 6a to penetrate to an identical depth in the toothing of the pinion 8 of the first roadway 7 and in the toothing of the pinion 14a of the second roadway 14.

On notera à ce propos qu'un engrenage horloger a typiquement, à l'entraxe nominal, un jeu de denture est de l'ordre de 0.16 x le pas angulaire d'une denture.Note in this connection that a watch gear typically has, at the nominal spacing, a set of teeth is of the order of 0.16 x the angular pitch of a toothing.

Soit par exemple pour un pignon de 20 dents un jeu angulaire de: 360°/20*0.16 soit : 2.68°. Pour une roue engrenant avec deux autres roues ou pignons comme dans le cas de la roue de minuterie du mouvement selon l'invention, le jeu angulaire se cumule, ce qui conduit à un jeu angulaire total de l'ordre 2x 2.68° soit 5,36°. Avec un tel jeu et compte tenu des tolérances de fabrication roues, il est difficile de garantir que la position de l'aiguille des minutes 4 portée par la chaussée 14 en regard de l'échelle des minutes du cadran 5 et le nombre de coups des minutes sonnés donné par le limaçon des minutes 11 porté par la chaussée soit en correspondance. Par conséquent, le mouvement de l'invention et notamment l'arrangement du mobile de minuterie 6 sur la bascule 17 dont la position est ajustable angulairement autour de l'axe de flexion FL permet de faire varier simultanément les entraxes nominaux respectifs entre la roue de minuterie et les première 7 et deuxième 14 chaussées et notamment de diminuer ces entraxes afin d'optimiser le jeu angulaire entre les dentures et permettre un engrenage avec un jeu angulaire assurant, d'une part, une correspondance parfaite entre la position des minutes et l'aiguille des minutes en regard du cadran et, d'autre part, une usure minimale des dentures en jeu.For example, for a pinion with 20 teeth, an angular clearance of: 360 ° / 20 * 0.16 is: 2.68 °. For a wheel meshing with two other wheels or gears as in the case of the movement timer wheel according to the invention, the angular clearance accumulates, which leads to a total angular clearance of the order 2x 2.68 ° or 5.36 °. With such a game and given the manufacturing tolerances of wheels, it is difficult to guarantee that the position of the minute hand 4 carried by the roadway 14 next to the scale of the minutes of the dial 5 and the number of shots. minutes given by the minute snail 11 carried by the roadway is in correspondence. Therefore, the movement of the invention and in particular the arrangement of the timer wheel 6 on the rocker 17 whose position is angularly adjustable about the axis of flexion FL makes it possible to simultaneously vary the nominal distance between the wheel of the invention. timer and the first 7 and second 14 roads and in particular to reduce these distances to optimize the angular clearance between the teeth and allow a gear with angular play ensuring, on the one hand, a perfect match between the position of the minutes and the minute hand opposite the dial and, secondly, minimal wear of the teeth in play.

En se référant plus particulièrement aux figures 3, 3a et 4 et 4a on voit la roue de minuterie 6a selon respectivement deux positions de réglage de la pénétration de sa denture dans la denture des pignons 8 et 14a des première et deuxième chaussées 7 et 14.With particular reference to Figures 3, 3a and 4 and 4a the timer wheel 6a is seen respectively in two positions for adjusting the penetration of its toothing in the toothing of the pinions 8 and 14a of the first and second pavements 7 and 14.

Aux figures 3 et 3a on voit que l'entraxe nominal entre la roue de minuterie 6a et les pignons 8 et 14a des première 7 et deuxième chaussées 14 a été réduit de telle manière que le jeu angulaire entre les dentures de cette roue et ces pignons est quasiment nul. Une telle configuration n'est pas optimale notamment en termes d'usure, même si elle assure une correspondance parfaite entre la position des minutes et l'aiguille des minutes en regard du cadran.the Figures 3 and 3a it is seen that the nominal distance between the timer wheel 6a and the pinions 8 and 14a of the first 7 and second pavement 14 has been reduced so that the angular clearance between the teeth of this wheel and these gears is virtually zero. Such a configuration is not optimal especially in terms of wear, even if it ensures a perfect match between the position of the minutes and the minute hand facing the dial.

Aux figures 4 et 4a en revanche, l'entraxe nominal entre la roue de minuterie 6a et les pignons 8 et 14a des première 7 et deuxième chaussées 14 a été réduit dans une moindre mesure par rapport aux figures 3 et 3a de telle manière que le jeu angulaire entre les dentures de cette roue et ces pignons est compris entre 2° et 4°. Cela qui assure une usure minimale des dentures et garantit une correspondance parfaite entre la position des minutes et l'aiguille des minutes en regard du cadran.the Figures 4 and 4a on the other hand, the nominal distance between the timer wheel 6a and the gears 8 and 14a of the first 7 and second roadways 14 has been reduced to a lesser extent with respect to Figures 3 and 3a such that the angular clearance between the teeth of this wheel and these gears is between 2 ° and 4 °. This ensures minimal wear of teeth and guarantees a perfect match between the position of the minutes and the minute hand opposite the dial.

Avantageusement, la denture de la roue de minuterie, qui comporte le plus grand nombre de dents, peut présenter des dents 6c qui comprennent chacune des flancs d'entrainement 6d ayant un segment rectiligne formant un angle au sommet compris entre 2 et 10°afin de faciliter la pénétration de cette denture dans celle des roues en pignons avec lesquelles elle engrène lorsque l'entraxe nominale est réduit par le pivotement de la bascule 15 au moment de l'ajustement de la position du mobile de minuterie 6.Advantageously, the toothing of the timer wheel, which has the largest number of teeth, may have teeth 6c which each comprise driving flanks 6d having a rectilinear segment forming an apex angle of between 2 and 10 ° in order to facilitate the penetration of this toothing in the gear wheels with which it meshes when the nominal distance is reduced by the pivoting of the rocker 15 at the time of adjustment of the position of the mobile timer 6.
