Description

Dispositif de guidage d'arbre d'horlogerie Domaine de l'invention  Time Domain Guide Device Field of the Invention
L'invention concerne un dispositif de pivotement d'un arbre de mouvement d'horlogerie comportant une pierre percée fixée dans un chaton traversée par un pivot dudit d'axe de révolution, et une pierre contre-pivot fixée indirectement sur une platine dudit mouvement par au moins ledit chaton, ladite pierre contre-pivot comportant une première surface d'appui agencée pour coopérer en butée avec l'extrémité distale dudit pivot.  The invention relates to a device for pivoting a clockwork movement shaft comprising a pierced stone fixed in a kitten traversed by a pivot of said axis of revolution, and a counter pivot stone indirectly fixed on a plate of said movement by at least said kitten, said counter pivot stone having a first bearing surface arranged to cooperate abutting with the distal end of said pivot.
L'invention concerne encore un mouvement d'horlogerie comportant un tel dispositif.  The invention also relates to a watch movement comprising such a device.
L'invention concerne encore une montre comportant un tel mouvement d'horlogerie ou/et un tel dispositif.  The invention also relates to a watch comprising such a watch movement or / and such a device.
L'invention concerne le domaine du guidage en pivotement des arbres d'horlogerie pour montres, et plus particulièrement des arbres de balancier.  The invention relates to the field of pivotal guidance of watch-making trees for watches, and more particularly of balance shafts.
Arrière-plan de l'invention Background of the invention
Les montres mécaniques ont des marches relativement isochrones. Mechanical watches have relatively isochronous steps.
Néanmoins cette relativité laisse place à une plage de marche pouvant varier de zéro à plusieurs dizaines de secondes par jour. Nevertheless, this relativity gives way to a range that can vary from zero to several tens of seconds per day.
Une des causes de ces variations de marche est la différence de comportement du pivot de balancier, en contact avec la pierre contre-pivot entre les deux positions horizontales. Cette différence de comportement est provoquée, par exemple, par les forces différentes du spiral, plus proche du pivot dans l'une des positions horizontales par rapport à l'autre, couplée au jeu du pivot dans l'orifice de la pierre.  One of the causes of these gait variations is the difference in the behavior of the pendulum pivot, in contact with the counter-pivot stone between the two horizontal positions. This difference in behavior is caused, for example, by the different forces of the hairspring, closer to the pivot in one of the horizontal positions relative to the other, coupled with the play of the pivot in the orifice of the stone.
En effet, quand la pierre contre-pivot est parallèle à la pierre percée, dans un montage classique, le pivot a un comportement instable dans les positions horizontales, qui est dû à son pivotement sur la pierre contre-pivot horizontale et au jeu de la pierre.  Indeed, when the counter-pivot stone is parallel to the pierced stone, in a conventional assembly, the pivot has an unstable behavior in the horizontal positions, which is due to its pivoting on the horizontal counter-pivot stone and the play of the Pierre.
Les contre-pivots ont pour fonctions essentielles, d'une part la diminution du frottement au niveau du pivot, et d'autre part la bonne répartition des huiles.

L'invention se propose de décrire différents moyens permettant d'influencer le comportement du pivot, et, par cet intermédiaire, la marche de la montre.

L'invention concerne un dispositif 10 de pivotement d'un arbre 1 de mouvement d'horlogerie 100 comportant une pierre percée 3 fixée dans un chaton 7. Cette pierre percée 3 est traversée par un pivot 2 d'un arbre 1 d'axe de révolution D. la présente description s'applique au cas préféré du guidage en pivotement d'un axe de balancier, naturellement l'invention est aussi utilisable avec profit pour le guidage d'autres arbres, tels que pivot d'ancre ou similaire,. L'arbre 1 est ici l'arbre du balancier-spiral.  The invention relates to a device 10 for pivoting a watch movement shaft 1 1 comprising a pierced stone 3 fixed in a kitten 7. This pierced stone 3 is traversed by a pivot 2 of a shaft 1 revolution D. the present description applies to the preferred case of guidance pivoting a balance shaft, naturally the invention is also used with advantage for guiding other trees, such as anchor pivot or the like. The shaft 1 is here the shaft of the sprung balance.
Une pierre de contre-pivot 4 est fixée indirectement sur une platine 6 du mouvement 100 par au moins l'intermédiaire du chaton 7. Dans les réalisations illustrées, le chaton 7 est porté par un cabochon 9, lequel est fixé à la platine 6.  A counter-pivot stone 4 is fixed indirectly on a plate 6 of the movement 100 by at least the intermediate of the kitten 7. In the illustrated embodiments, the kitten 7 is carried by a cabochon 9, which is fixed to the plate 6.
Selon l'invention, cette pierre contre-pivot 4 comporte une première surface d'appui 5 unique, qui est agencée pour coopérer en butée avec l'extrémité distale du pivot 2, tandis que la partie cylindrique du pivot 2 coopère avec l'orifice 31 , généralement olivé, que comporte la pierre percée 3.  According to the invention, this counter-pivoting stone 4 comprises a single first bearing surface 5, which is arranged to cooperate in abutment with the distal end of the pivot 2, while the cylindrical portion of the pivot 2 cooperates with the orifice 31, generally olives, that includes the pierced stone 3.
Dans une réalisation économique, la surface d'appui 5 est plane, tel que visible notamment sur les figures 1 , 3, 4, 5, 7, 8, 9, 13, 15, et 16.  In an economic embodiment, the bearing surface 5 is flat, as can be seen in particular in FIGS. 1, 3, 4, 5, 7, 8, 9, 13, 15, and 16.
Le dispositif 10 selon l'invention est agencé de façon à ce que, en position de butée du pivot 2 sur la pierre contre-pivot 4, la normale N au plan tangent PT commun au pivot 2 et à la première surface d'appui 5 est oblique par rapport à l'axe D selon un angle de dévers Θ non nul. The device 10 according to the invention is arranged so that, in the abutment position of the pivot 2 on the counter pivot stone 4, the normal N to the tangent plane PT common to the pivot 2 and the first bearing surface 5 is oblique with respect to the axis D at a non-zero tilt angle.
Cette disposition permet d'éviter l'inconvénient de l'art antérieur du flottement du pivot en glissement sur une pierre contre-pivot horizontale dans les limites permises par le jeu du pivot dans l'orifice de la pierre percée. En effet, le fait d'incliner la pierre contre-pivot 4 permet d'influencer la position du pivot dans les positions horizontales. Une inclinaison de l'ordre de 3° permet de ne pas perturber la lubrification et de maintenir au niveau du pivot la goutte d'huile nécessaire. Si la légère augmentation de frottement dans la position au plat, résultant de la position inclinée de la pierre contre-pivot, pénalise quelque peu le rendement, toutefois la valeur du frottement en position pendu se rapproche de celle au plat, ce qui est le but recherché. Il s'agit, en somme, non de minimiser les frottements, mais surtout de les égaliser dans les différentes positions dans l'espace de l'axe de balancier.  This arrangement avoids the disadvantage of the prior art flotation of the pivot sliding on a horizontal counter-pivot stone within the limits permitted by the play of the pivot in the hole of the pierced stone. Indeed, the tilting of the counter pivot stone 4 can influence the position of the pivot in the horizontal positions. An inclination of about 3 ° makes it possible not to disturb the lubrication and to maintain at the pivot the drop of oil required. If the slight increase in friction in the flat position, resulting from the inclined position of the counter-pivot stone, slightly penalizes the yield, however the value of the friction in the hung position approaches that of the flat, which is the purpose research. It is, in short, not to minimize the friction, but especially to equalize them in the different positions in the space of the axis of balance.
Cette normale N et cet axe D définissent ensemble un plan dit de contre- pivot PCP, qui a une première orientation angulaire selon un angle de lacet a par rapport à une direction de référence DR de la platine 6.  This normal N and this axis D together define a so-called PCP counter-pivot plane, which has a first angular orientation at a yaw angle α with respect to a reference direction DR of the plate 6.
Selon l'invention, le dispositif 10 comporte des moyens de réglage 20 permettant d'influencer le déplacement du pivot 2 dans l'orifice 31 de la pierre percée pour le réglage et l'ajustement de la marche du mouvement 100 auquel il est incorporé, par une réduction des écarts de marche entre les deux positions horizontales. Plus particulièrement, ces moyens de réglage 20 sont des moyens de réglage de l'angle de lacet a ou/et de l'angle de dévers e. Ces moyens de réglage ne doivent pas être confondus avec des bras élastiques, ou encore des ressorts, de certains paliers de l'art antérieur, qui sont en général uniquement dévolus à des fonctions de maintien ou/et de rappel élastique, et ne peuvent en aucun cas constituer des moyens de réglage reproductibles..  According to the invention, the device 10 comprises adjustment means 20 for influencing the displacement of the pivot 2 in the hole 31 of the pierced stone for the adjustment and adjustment of the movement step 100 in which it is incorporated, by reducing the differences between the two horizontal positions. More particularly, these adjustment means 20 are means for adjusting the yaw angle a and / or the tilt angle. These adjustment means must not be confused with resilient arms, or even springs, of certain bearings of the prior art, which are in general solely devoted to functions of holding or / and elastic return, and can not in no case constitute reproducible control means.
L'inclinaison de la surface d'appui 5 unique au niveau de la pierre contre- pivot 4, par rapport à l'axe DO du pivot 2, selon un angle de dévers e, comme visible notamment sur la figure 1 , permet d'influencer le déplacement du pivot 2 dans son orifice 31 , ainsi que la chronométrie résultant de ce déplacement.  The inclination of the single bearing surface 5 at the level of the pivoting stone 4, with respect to the axis DO of the pivot 2, according to a canting angle, as can be seen in particular in FIG. influencing the displacement of the pivot 2 in its orifice 31, as well as the chronometry resulting from this displacement.
L'inclinaison du plan de contre-pivot PCP par rapport à une direction de référence DR, correspondant à une platine 6 recevant le dispositif 10, d'un angle de lacet a, tel que visible sur la figure 2, permet de corriger et régler la chronométrie, en particulier la différence de marche entre les deux positions horizontales. The inclination of the counter-pivot plane PCP with respect to a reference direction DR, corresponding to a plate 6 receiving the device 10, of a lace angle a, as visible in FIG. 2, makes it possible to correct and adjust the chronometry, in particular the difference between the two horizontal positions.
De préférence, la pierre percée 3 et la pierre contre-pivot 4 sont fixées ensemble dans le chaton 7, dans lequel la pierre contre-pivot 4 est poussée vers la pierre percée 3 par au moins un ressort pare-chocs 8, en appui sur un épaulement du chaton 7.  Preferably, the pierced stone 3 and the counter-pivot stone 4 are fixed together in the kitten 7, in which the counter-pivoting stone 4 is pushed towards the pierced stone 3 by at least one bumper spring 8, resting on a shoulder of the kitten 7.
Dans une version particulière de l'invention, dans certaines de ses variantes, ces moyens de réglage 20 comportent des moyens de positionnement 21 , soit du chaton 7 monté mobile en pivotement par rapport à la platine 6, soit d'un cabochon 9 enfermant le chaton 7 et monté mobile par rapport à la platine 6.  In a particular version of the invention, in some of its variants, these adjustment means 20 comprise positioning means 21, either the kitten 7 pivotally mounted relative to the plate 6, or a cabochon 9 enclosing the kitten 7 and mounted movably relative to the plate 6.
La mobilité du chaton 7 par rapport à la platine 6 peut être indirecte, c'est le cas des figures 12 et 15 où le chaton 7 pivote par rapport au cabochon 9 qui est immobile par rapport à la platine 6.  The mobility of the kitten 7 relative to the plate 6 may be indirect, this is the case of Figures 12 and 15 where the kitten 7 pivots with respect to the cabochon 9 which is stationary relative to the plate 6.
La mobilité du cabochon 9 par rapport à la platine 6 est, de préférence restreinte à un simple pivotement tel que visible sur les figures 13 et 14, sans jeu ou de préférence avec friction, ou encore à un mouvement de translation différentiel, par rapport à la platine 6, de trois points de sa périphérie, avec un jeu réduit n'autorisant que ce gauchissement de la pierre contre-pivot 4 par rapport à la platine 6, tel que visible sur la figure 16.  The mobility of the cabochon 9 with respect to the plate 6 is preferably restricted to a simple pivoting as can be seen in FIGS. 13 and 14, without play or preferably with friction, or else with a differential translational movement, with respect to the plate 6, three points of its periphery, with a reduced clearance allowing only this warpage of the counter-pivot stone 4 relative to the plate 6, as visible in Figure 16.
Bien sûr, on peut encore combiner la mobilité du chaton 7 par rapport au cabochon 9, et du cabochon 9 par rapport à la platine 6, mais la simplicité des réglages s'en ressent, et le réglage du chaton 7 seul ou du cabochon 9 seul s'avère suffisant dans la plupart des cas pour équilibrer la marche entre les différentes positions.  Of course, it is still possible to combine the mobility of the kitten 7 with respect to the cabochon 9, and the cabochon 9 with respect to the plate 6, but the simplicity of the settings is affected, and the setting of the kitten 7 alone or the cabochon 9 alone is sufficient in most cases to balance the march between different positions.
Avantageusement, les moyens de réglage 20 comportent des moyens d'indexage angulaire 22 pour maintenir les réglages effectués sur la montre. Ces moyens d'indexage angulaire 22 peuvent, là encore, concerner, ou le chaton 7 monté mobile en pivotement par rapport à la platine 6 comme sur la figure 12 où le chaton peut prendre plusieurs positions discrètes, ou/et le cabochon 9 enfermant le chaton 7 et monté mobile par rapport à la platine 6 comme sur la figure 14 où un pignon denté 25 permet un réglage fin d'une couronne dentée 94 solidaire du cabochon 9.  Advantageously, the adjustment means 20 comprise angular indexing means 22 for maintaining the adjustments made on the watch. These angular indexing means 22 may, again, concern, or the kitten 7 pivotally mounted relative to the plate 6 as in Figure 12 where the kitten can take several discrete positions, and / or the cabochon 9 enclosing the kitten 7 and mounted movable relative to the plate 6 as in Figure 14 where a toothed gear 25 allows fine adjustment of a ring gear 94 secured to the cabochon 9.
La figure 12 illustre une variante avec une pierre contre-pivot 4 inclinée et un chaton 7 indexable en plusieurs positions discrètes, de façon à effectuer un réglage de la marche, et à maintenir ce réglage. Le cabochon 9 comporte des alvéoles 93, dans lesquelles peut se loger un doigt 72 solidaire du chaton 7, ces alvéoles 93 et ce doigt 72 constituant ensemble les moyens de réglage 20 ainsi que les moyens d'indexage 22. La pierre contre-pivot 4 est chassée ou indexée dans le chaton 7. FIG. 12 illustrates a variant with an inclined counter-pivot stone 4 and a kitten 7 indexable in several discrete positions, so as to effect a adjust the gait, and maintain this setting. The cabochon 9 comprises cavities 93, in which can be housed a finger 72 integral with the kitten 7, these cells 93 and the finger 72 together constituting the adjusting means 20 and the indexing means 22. The pivot-pivoting stone 4 is hunted or indexed in the kitten 7.
Comme le montrent les figures, l'invention peut être mise en œuvre selon de nombreuses variantes. De façon commune aux variantes illustrées, le dispositif 10 comporte un cabochon 9 enfermant le chaton 7 et le ressort pare-chocs 8, et qui est monté mobile en pivotement dans la platine 6. Ce cabochon 9 comporte une deuxième surface de référence 91 faisant face à une deuxième surface d'appui complémentaire 61 de la platine 6.  As shown in the figures, the invention can be implemented according to many variants. Commonly to the illustrated variants, the device 10 comprises a cabochon 9 enclosing the kitten 7 and the bumper spring 8, and which is pivotally mounted in the plate 6. This cabochon 9 has a second reference surface 91 facing to a second complementary bearing surface 61 of the plate 6.
Dans une variante illustrée notamment sur la figure 8, la première surface d'appui 5 est perpendiculaire par rapport à l'axe DO de l'orifice 31 de la pierre percée 3 pour le guidage du pivot 2. Le chaton 7 est monté oblique dans le cabochon 9 par rapport à la deuxième surface de référence 91 dans une position unique déterminée. Sur la figure 8, le cabochon 9 est monté aligné avec l'axe D de balancier, le chaton 7 est monté coaxial à ce cabochon 9. Le chaton 7 comporte deux logements 75 et 76 inclinés de la valeur de l'angle de dévers e, de préférence voisin de 3°, et parallèles entre eux : le premier logement 75 pour une pierre percée 3 de guidage du pivot 2, l'orifice de passage 31 étant ainsi incliné par rapport à l'axe D du pivot 2 ; et l'autre logement 76 pour la réception de la pierre contre-pivot 4, sensiblement parallèle à la pierre percée 3, et qui est maintenue dans le cabochon 9 par un ressort pare-chocs 8. L'extrémité du pivot 2 est ainsi en appui sur une surface d'appui plane 5 de la pierre contre-pivot 4, selon un angle de dévers Θ identique à l'angle d'inclinaison Θ de la pierre contre-pivot et de la pierre percée dans le chaton 7.  In a variant illustrated in particular in FIG. 8, the first bearing surface 5 is perpendicular with respect to the axis DO of the orifice 31 of the pierced stone 3 for guiding the pivot 2. The kitten 7 is mounted obliquely in the cabochon 9 relative to the second reference surface 91 in a single determined position. In Figure 8, the cabochon 9 is mounted aligned with the axis D balance, the kitten 7 is mounted coaxial with the cabochon 9. The kitten 7 has two housings 75 and 76 inclined the value of the angle of tilt , preferably close to 3 °, and parallel to each other: the first housing 75 for a pierced stone 3 for guiding the pivot 2, the passage opening 31 thus being inclined with respect to the axis D of the pivot 2; and the other housing 76 for receiving the counter-pivot stone 4, substantially parallel to the pierced stone 3, and which is held in the cabochon 9 by a bumper spring 8. The end of the pivot 2 is thus in resting on a flat support surface 5 of the counter-pivot stone 4, at a slope angle Θ identical to the angle of inclination Θ of the counter-pivot stone and the pierced stone in the kitten 7.
De façon plus particulière, le cabochon 9 comporte un logement 92 pour la réception du chaton 7, lequel comporte une surface externe 71 qui est oblique par rapport à l'axe D0 de l'orifice 31 dans une position unique déterminée. Ce logement 92 est parallèle à la direction de la deuxième surface de référence 91 du cabochon 9.  More particularly, the cabochon 9 comprises a housing 92 for receiving the kitten 7, which has an outer surface 71 which is oblique with respect to the axis D0 of the orifice 31 in a single determined position. This housing 92 is parallel to the direction of the second reference surface 91 of the cabochon 9.
Dans une variante illustrée notamment sur les figures 9 et 13, le cabochon 9 comporte un logement 92 pour la réception du chaton 7, et ce logement 92 est oblique par rapport à la deuxième surface de référence 91 du cabochon 9 dans une position unique déterminée. Ce chaton 7 comporte une surface externe 71 qui est de révolution et coaxiale à l'axe DO de l'orifice 31 de la pierre percée 3. In a variant illustrated in particular in Figures 9 and 13, the cabochon 9 comprises a housing 92 for receiving the kitten 7, and the housing 92 is oblique with respect to the second reference surface 91 of the cabochon 9 in a single, determined position. This kitten 7 has an outer surface 71 which is of revolution and coaxial with the axis DO of the orifice 31 of the pierced stone 3.
La figure 9 montre ainsi un cabochon 9, sensiblement de révolution, monté aligné avec l'axe D de balancier par une portée cylindrique 91 coopérant avec un alésage 63 de la platine 6, et qui porte un logement 92 incliné de la valeur de l'angle de dévers e, de préférence voisin de 3°, pour la réception du chaton 7. Ce chaton 7 comporte deux logements parallèles entre eux, l'un 75 pour une pierre percée 3 de guidage du pivot 2, l'orifice de passage 31 étant ainsi incliné par rapport à l'axe D du pivot 2, et l'autre 76 pour la réception de la pierre contre-pivot 4, sensiblement parallèle à la pierre percée 3, et qui est maintenue dans le cabochon 9 par un ressort pare-chocs 8, l'extrémité du pivot 2 est ainsi en appui sur une surface d'appui 5 plane de la pierre contre-pivot 4, selon un angle de dévers Θ identique à l'angle d'inclinaison Θ du chaton 7 dans le cabochon 9. Le même montage est visible sur la figure 13 qui représente, un tel chaton 7 incliné dans un cabochon 9 monté droit et à friction dans une platine 6 et en appui sur celle-ci, ce cabochon 9 comportant des fentes de vis 93 pour réglage angulaire d'un angle de lacet a avec un outil tel qu'un tournevis, de façon à effectuer un réglage de la marche par ajustement de cet angle de lacet a, et à maintenir ce réglage sous l'action de la friction.  FIG. 9 thus shows a cabochon 9, substantially of revolution, mounted aligned with the axis D of the balance beam by a cylindrical bearing surface 91 cooperating with a bore 63 of the plate 6, and which carries a housing 92 inclined by the value of the tilt angle e, preferably close to 3 °, for receiving the kitten 7. This kitten 7 has two recesses parallel to each other, one 75 for a piercing stone 3 for guiding the pivot 2, the passage opening 31 being thus inclined with respect to the axis D of the pivot 2, and the other 76 for the reception of the counter-pivot stone 4, substantially parallel to the pierced stone 3, and which is held in the cabochon 9 by a bent spring shocks 8, the end of the pivot 2 is thus resting on a flat bearing surface 5 of the counter-pivot stone 4, at a slope angle Θ identical to the angle of inclination Θ of the kitten 7 in the cabochon 9. The same assembly is visible in FIG. 13 which represents, such a kitten 7 inclined in a cabochon 9 mounted directly and frictionally in a plate 6 and resting on it, this cabochon 9 having screw slots 93 for angular adjustment of a yaw angle a with a tool such as a screwdriver, so adjusting the step by adjusting this yaw angle a, and maintaining this adjustment under the action of the friction.
Dans une variante illustrée notamment sur la figure 16, la première surface d'appui 5 est perpendiculaire par rapport à l'axe DO de l'orifice 31 que comporte la pierre percée 3 pour le guidage du pivot 2. Le chaton 7 est monté parallèle, dans ce cabochon 9, par rapport à la deuxième surface de référence 91. Et la deuxième surface de référence 91 est maintenue oblique par rapport à la deuxième surface d'appui complémentaire 61 de la platine 6. Plus particulièrement, le cabochon 9 est inséré avec jeu dans un logement 64 de la platine 6, sur laquelle il est maintenu serré par trois vis 23 comportant chacune une gorge 27 enserrant un flasque 96 du pourtour du cabochon 9, pour le réglage à la fois de l'angle de dévers Θ et de l'angle de lacet a. De préférence, tel qu'illustré, au moins une des vis 23 est maintenue en appui, par une portée 241 d'une collerette 28 délimitant cette gorge 27, sur une face 61 de la platine 6, pour faciliter le réglage.  In a variant illustrated in particular in Figure 16, the first bearing surface 5 is perpendicular to the axis OD of the orifice 31 that includes the pierced stone 3 for guiding the pivot 2. The kitten 7 is mounted parallel in this cabochon 9, relative to the second reference surface 91. And the second reference surface 91 is held oblique with respect to the second complementary bearing surface 61 of the plate 6. More particularly, the cabochon 9 is inserted with play in a housing 64 of the plate 6, on which it is held tight by three screws 23 each having a groove 27 enclosing a flange 96 of the periphery of the cabochon 9, for the adjustment of both the tilt angle Θ and of the yaw angle a. Preferably, as illustrated, at least one of the screws 23 is held in abutment, by a bearing surface 241 of a flange 28 delimiting said groove 27, on a face 61 of the plate 6, to facilitate adjustment.
Dans une variante illustrée notamment sur la figure 3, la normale de la première surface d'appui 5 est oblique par rapport à l'axe DO de l'orifice 31 de la pierre percée 3 pour le guidage du pivot 2, selon l'angle de dévers Θ voisin de 3°. Le chaton 7 est monté parallèle dans le cabochon 9 par rapport à la deuxième surface de référence 91 . In a variant illustrated in particular in FIG. 3, the normal of the first bearing surface 5 is oblique with respect to the axis DO of the orifice 31 of the pierced stone 3 for guiding the pivot 2, according to the angle tilt Θ close to 3 °. The kitten 7 is mounted parallel in the cabochon 9 relative to the second reference surface 91.
Dans une variante illustrée notamment sur la figure 14, les moyens de réglage 20 comportent des moyens d'entraînement en pivotement 24 du cabochon 9. Sur la figure 14, le cabochon 9 porte une pierre contre-pivot 4 inclinée, ce cabochon 9 comporte une denture périphérique 94 engrenant avec un pignon de manœuvre 25 à fente de vis 26 monté à friction dans la platine, de façon à effectuer avec un tournevis un réglage de la marche par pivotement du cabochon 9 complet et réglage de son angle de lacet a, et à maintenir ce réglage sous l'action de la friction.  In a variant illustrated in particular in FIG. 14, the adjustment means 20 comprise pivoting drive means 24 of the cabochon 9. In FIG. 14, the cabochon 9 bears an inclined counter-pivot stone 4. This cabochon 9 comprises a peripheral toothing 94 meshing with a drive gear 25 with a screw slot 26 frictionally mounted in the plate, so as to perform with a screwdriver a step adjustment by pivoting the complete cabochon 9 and adjustment of its yaw angle a, and to maintain this adjustment under the action of the friction.
Dans une variante illustrée notamment sur la figure 9, la surface d'appui complémentaire 61 de la platine 6 est un alésage 63 sensiblement parallèle à l'axe D, et la première surface d'appui 5 est perpendiculaire à l'axe DO de l'orifice 31 de la pierre percée 3, et le chaton 7 est monté oblique dans le logement oblique 92 du cabochon 9 par rapport à la deuxième surface de référence 91 qui est cylindrique, dans une position unique déterminée.  In a variant illustrated in particular in Figure 9, the complementary bearing surface 61 of the plate 6 is a bore 63 substantially parallel to the axis D, and the first bearing surface 5 is perpendicular to the axis OD of the orifice 31 of the pierced stone 3, and the kitten 7 is mounted obliquely in the oblique housing 92 of the cabochon 9 relative to the second reference surface 91 which is cylindrical, in a single determined position.
Dans une variante illustrée notamment sur la figure 7, la surface d'appui complémentaire 61 de la platine 6 est un alésage 63 oblique par rapport à l'axe D avec une inclinaison de l'ordre de 3°, et la première surface d'appui 5 est perpendiculaire par rapport à l'axe DO de l'orifice 31 de la pierre percée 3, lequel est incliné par rapport à l'axe du pivot du fait de l'inclinaison du cabochon dans la platine. Le chaton 7 est monté coaxial dans le cabochon 9 parallèle par rapport à la deuxième surface de référence 91 qui est cylindrique, dans une position unique déterminée. L'extrémité du pivot 2 est ainsi en appui sur une surface d'appui 5 plane de la pierre contre-pivot 4, selon un angle de dévers Θ identique à l'angle d'inclinaison du cabochon 9 dans la platine 6.  In a variant illustrated in particular in Figure 7, the complementary bearing surface 61 of the plate 6 is a bore 63 oblique with respect to the axis D with an inclination of the order of 3 °, and the first surface of 5 support is perpendicular to the axis OD of the hole 31 of the pierced stone 3, which is inclined relative to the axis of the pivot due to the inclination of the cabochon in the plate. The kitten 7 is mounted coaxially in the cabochon 9 parallel to the second reference surface 91 which is cylindrical, in a single determined position. The end of the pivot 2 is thus resting on a flat support surface 5 of the counter-pivoting stone 4, at a slope angle Θ identical to the angle of inclination of the cabochon 9 in the plate 6.
Dans une variante illustrée notamment sur la figure 15, le cabochon 9 et le chaton 7 sont droits et coaxiaux, le cabochon 9 est monté mobile en pivotement dans la platine 6. La normale de la première surface d'appui 5 est oblique par rapport à l'axe DO de l'orifice 31 de la pierre percée 3. Le chaton 7 est monté parallèle dans le cabochon 9 par rapport à la deuxième surface de référence 91. Le ressort pare-chocs 8 coopère avec une nervure 41 ou une rainure 42 de la surface de la pierre contre-pivot 4 opposée à la surface d'appui 5 de l'extrémité du pivot 2. Le cabochon 9 comporte une pluralité de logements 95 : 95A, 95B, 95C, 95D, pour la réception et le blocage d'une boucle 82 ou des bras d'extrémité 83 du ressort pare-chocs 8, pour indexer le chaton 7 en différentes positions par la lyre du ressort 8, qui est elle-même indexée dans les logements 95 en encoches du cabochon 9. In a variant illustrated in particular in Figure 15, the cabochon 9 and the kitten 7 are straight and coaxial, the cabochon 9 is pivotally mounted in the plate 6. The normal of the first bearing surface 5 is oblique with respect to the axis DO of the hole 31 of the pierced stone 3. The kitten 7 is mounted parallel in the cap 9 relative to the second reference surface 91. The bumper spring 8 cooperates with a rib 41 or a groove 42 the surface of the counter-pivot stone 4 opposite to the bearing surface 5 of the end of the pivot 2. The cabochon 9 comprises a plurality of housings 95: 95A, 95B, 95C, 95D, for receiving and locking a loop 82 or end arms 83 of the bumper spring 8, to index the kitten 7 in different positions by the lyre of the spring 8, which is itself indexed in the housing 95 in cabochon notches 9.
Dans certaines variantes, la pierre contre-pivot 4 comporte une surface creuse, avantageusement décentrée, notamment sphérique ou conique, pour la réception de la partie distale du pivot 2, cette surface creuse décentrée comportant des bords obliques, surtout du côté spiral, pour sortir l'axe 1 de la position verticale, et qui influence le comportement du pivot 2 dans les positions horizontales La surface d'appui 5 peut ainsi être constituée, de façon non limitative, d'un creux 51 décentré par rapport à l'axe DO de l'orifice 31 de la pierre percée 3 visible sur la figure 6, ou d'une première rainure 52 à profil en vé centrée sur cet axe DO dudit visible sur la figure 1 1 , ou encore d'une deuxième rainure 53 à profil en vé décentrée par rapport à cet axe DO visible sur la figure 10.  In certain variants, the counter-pivoting stone 4 comprises a hollow surface, advantageously off-center, in particular spherical or conical, for receiving the distal portion of the pivot 2, this off-center hollow surface having oblique edges, especially on the spiral side, for exiting the axis 1 of the vertical position, and which influences the behavior of the pivot 2 in the horizontal positions The bearing surface 5 can thus be constituted, without limitation, a hollow 51 off-center with respect to the axis DO of the orifice 31 of the pierced stone 3 visible in FIG. 6, or of a first groove 52 with a V-shaped profile centered on this axis DO that is visible in FIG. 11, or else with a second groove 53 with a profile Vee eccentric with respect to this axis DO visible in Figure 10.
Dans une réalisation particulière, le dispositif 10 comporte des moyens d'attraction ou de répulsion 30 du pivot 2 selon une direction sensiblement orthogonale à l'axe D du pivot 2. La mise en œuvre de moyens d'attraction ou de répulsion 30 du pivot 2, selon une direction sensiblement orthogonale à l'axe D du pivot 2, influence la position du pivot dans les positions horizontales.  In a particular embodiment, the device 10 comprises means of attraction or repulsion 30 of the pivot 2 in a direction substantially orthogonal to the axis D of the pivot 2. The implementation of means of attraction or repulsion 30 of the pivot 2, in a direction substantially orthogonal to the axis D of the pivot 2, influences the position of the pivot in the horizontal positions.
Dans une première variante visible sur la figure 4, ces moyens d'attraction ou de répulsion 30 sont constitués par un électret ou un aimant 30A générant un champ électrostatique ou magnétique, et le pivot 2, étant en matériau métallique conducteur, est sensible à ce champ et subit une force tendant à le plaquer au moins sur un bord de l'orifice 31 de la pierre percée 3 ; quand la pierre contre- pivot 4 est inclinée, l'orientation du champ dans le même plan que la normale à la surface d'appui 5 améliore encore la régularité de la marche. In a first variant visible in FIG. 4, these attraction or repulsion means 30 are constituted by an electret or a magnet 30A generating an electrostatic or magnetic field, and the pivot 2, being made of metallic conducting material, is sensitive to field and undergoes a force tending to press it at least on an edge of the orifice 31 of the pierced stone 3; when the counter pivot stone 4 is inclined, the orientation of the field in the same plane as the normal to the bearing surface 5 further improves the regularity of the step.
Dans une deuxième variante visible sur la figure 5, ces moyens d'attraction ou de répulsion 30 sont constitués par au moins un moyen de rappel élastique ou ressort 30B exerçant un effort radial sur le pivot 2, notamment en agissant directement sur l'axe 1 du balancier.  In a second variant visible in FIG. 5, these attraction or repulsion means 30 are constituted by at least one elastic return means or spring 30B exerting a radial force on the pivot 2, in particular by acting directly on the axis 1 of the pendulum.
L'invention concerne encore un mouvement d'horlogerie 100 comportant un tel dispositif 10.  The invention also relates to a watch movement 100 comprising such a device 10.
L'invention concerne encore une montre 200 comportant un tel mouvement d'horlogerie 100 ou/et un tel dispositif 10. En somme, l'inclinaison de la pierre contre-pivot 4 par rapport à l'axe D est favorable en soi. L'inclinaison du chaton 7 complet permet d'influencer la position du pivot 2 dans les positions horizontales. En complément, l'action sur le cabochon 9, ou l'action combinée sur le cabochon 9 et sur le chaton 7, permet d'égaliser les marches entre positions, en modifiant les influences sur le pivot 2. The invention also relates to a watch 200 comprising such a watch movement 100 and / or such a device 10. In sum, the inclination of the counter-pivoting stone 4 with respect to the axis D is favorable in itself. The inclination of the complete kitten 7 can influence the position of the pivot 2 in the horizontal positions. In addition, the action on the cabochon 9, or the combined action on the cabochon 9 and the kitten 7, makes it possible to equalize the steps between positions, by modifying the influences on the pivot 2.
Sur la base des pierres contre-pivot 4 inclinées et des pierres contre-pivot 4 avec des logements creux, en faisant tourner la pierre contre-pivot 4 sus ou sous par rapport au balancier, on influence la marche dans les positions horizontales correspondantes.  On the basis of the counter-pivoting stones 4 inclined and counter-pivoting stones 4 with hollow housing, by rotating the counter-pivot stone 4 above or below relative to the balance, the step is influenced in the corresponding horizontal positions.
Ce principe peut être appliqué à la rotation de la pierre dans l'amortisseur pare-chocs réalisé avec l'incorporation du ressort pare-chocs 8 dans le cabochon 9, à la rotation du chaton 7 et de la pierre contre-pivot 4, à la rotation de l'amortisseur complet et à la rotation du pont.  This principle can be applied to the rotation of the stone in the bumper damper realized with the incorporation of the bumper spring 8 in the cabochon 9, the rotation of the kitten 7 and the stone against pivot 4, to the rotation of the complete damper and the rotation of the bridge.
Toutes les solutions exposées sont applicables à des amortisseurs avec chatons classiques, ou avec chatons suspendus, ou semi-suspendus.  All solutions shown are applicable to shock absorbers with traditional kittens, or with suspended kittens, or semi-suspended.
Les avantages découlant des caractéristiques décrites ci-dessus permettent la maîtrise des écarts de marche des montres entre les positions.  The advantages deriving from the features described above make it possible to control the variations in the running of the watches between the positions.
