Description

Mouvement de montre à tourbillon à un seul axe  Single-axis tourbillon watch movement
Domaine technique Technical area
[0001] La présente invention concerne un mouvement de montre à tourbillon à un seul axe. The present invention relates to a tourbillon watch movement with a single axis.
Etat de la technique State of the art
[0002] Les mouvements de montre mécanique sont régulés à l'aide d'un organe réglant qui comporte le plus souvent un spiral et un balancier. Le spiral est soumis à la gravité et se déforme sous son propre poids, ce qui entraîne une variation de la marche de la montre. La déformation dépend à la fois de l'inclinaison du spiral par rapport à la verticale, et de The mechanical watch movements are regulated by means of a regulating member which more often comprises a balance spring and a balance wheel. The hairspring is subjected to gravity and deforms under its own weight, which causes a variation in the running of the watch. The deformation depends both on the inclination of the hairspring relative to the vertical, and
l'orientation du spiral dans son propre plan. [0003] Les mouvements de montre à tourbillon comportent une cage pour maintenir l'ensemble balancier-spiral. Cette cage tourne autour d'un axe parallèle ou coaxial à l'arbre du balancier. Le spiral occupe ainsi successivement différentes orientations dans son propre plan ; ainsi, en position verticale, la position d'attache au coq passe par toutes les positions entre le point le plus bas et le plus haut, ce qui permet de rendre la marche de la montre indépendante de la façon dont le spiral est orienté dans son propre plan. the spiral's orientation in its own plane. [0003] The tourbillon watch movements comprise a cage for maintaining the balance-sprung assembly. This cage rotates about an axis parallel or coaxial with the balance shaft. The spiral thus occupies successively different orientations in its own plane; thus, in a vertical position, the position of attachment to the cock passes through all the positions between the lowest point and the highest, which makes the running of the watch independent of the way the spiral is oriented in its own plan.
[0004] Les tourbillons conventionnels à un seul axe ne modifient cependant pas le plan du spiral ; par exemple, un spiral qui est en position horizontale reste en position horizontale pendant toute la rotation de la cage. La marche de la montre varie donc entre la position verticale et la position horizontale, et le gain de précision est limité. [0004] Conventional vortices with only one axis do not however modify the plane of the spiral; for example, a hairspring that is in a horizontal position remains in a horizontal position during the entire rotation of the cage. The movement of the watch therefore varies between the vertical position and the horizontal position, and the gain in precision is limited.
[0005] On connaît par ailleurs des tourbillons à deux axes, et même des tourbillons à trois axes. Dans ces constructions, un des axes permet de varier l'orientation du spiral dans son propre plan ; le ou les autres axes permettent de varier l'inclinaison de ce plan par rapport à la verticale. Ces constructions sont cependant coûteuses, fragiles et volumineuses. [0005] Two-axis vortices and even three-axis vortices are also known. In these constructions, one of the axes makes it possible to vary the orientation of the spiral in its own plane; the other axis allow to vary the inclination of this plane relative to the vertical. These constructions are however expensive, fragile and bulky.
[0006] EP1564608 décrit un tourbillon dans lequel la cage est montée en biais sur son axe de rotation. Cet axe est perpendiculaire à la platine en sorte que l'inclinaison de l'ensemble balancier-spiral par rapport à la platine reste constante. [0006] EP1564608 describes a vortex in which the cage is mounted at an angle on its axis of rotation. This axis is perpendicular to the plate so that the inclination of the sprung-balance assembly relative to the plate remains constant.
[0007] EP1686435 décrit un tourbillon dont la cage est montée perpendiculairement à son axe de rotation parallèle à la platine. EP1686435 describes a vortex whose cage is mounted perpendicular to its axis of rotation parallel to the plate.
L'orientation du spiral dans son plan reste constante. L'axe de rotation de la cage reste toujours dans le plan du spiral. The spiral orientation in its plane remains constant. The axis of rotation of the cage remains in the plane of the spiral.
[0008] CH694598 décrit un tourbillon avec deux cages, une première cage extérieure présentant une roue fixe montée autour de l'axe de rotation du tourbillon, tandis qu'une deuxième cage intérieure présente une roue fixe montée autour d'un axe orthogonal à l'axe de rotation du tourbillon, cette deuxième cage retenant le balancier qui présente un axe de rotation incliné par rapport à l'axe de rotation du tourbillon. Cet agencement permet de placer le balancier avec une inclinaison changeante par rapport à la platine mais il est complexe. CH694598 describes a vortex with two cages, a first outer cage having a fixed wheel mounted around the axis of rotation of the vortex, while a second inner cage has a fixed wheel mounted around an axis orthogonal to the axis of rotation of the vortex, this second cage holding the balance which has an axis of rotation inclined relative to the axis of rotation of the vortex. This arrangement makes it possible to place the balance with a changing inclination with respect to the plate but it is complex.
[0009] WO2015021765 décrit un mécanisme à tourbillon à trois axes dont l'ensemble balancier-spiral présente un axe qui est perpendiculaire à la platine en sorte que l'inclinaison de l'ensemble balancier-spiral par rapport à la platine reste constante. [0009] WO2015021765 discloses a three-axis tourbillon mechanism whose sprung balance assembly has an axis which is perpendicular to the plate so that the inclination of the sprung-balance assembly relative to the plate remains constant.
[0010] WO2015121767 décrit un mécanisme d'entraînement avec un tourbillon incliné sur une plaque frontale dont l'inclinaison par rapport à la platine est constante. [0010] WO2015121767 discloses a drive mechanism with an inclined vortex on a front plate whose inclination relative to the platen is constant.
[0011] CH710893 décrit un mouvement de pièce d'horlogerie à tourbillon dans lequel la cage portant l'ensemble balancier-spiral tourne autour d'un axe perpendiculaire par rapport au bâti, cette cage étant inclinée par rapport à cet axe. En conséquence, l'inclinaison de l'ensemble balancier-spiral par rapport à la platine reste constante. CH710893 describes a tourbillon timepiece movement in which the cage carrying the sprung-balance assembly rotates about an axis perpendicular to the frame, this cage being inclined with respect to this axis. As a result, the inclination of the sprung-balance assembly relative to the platen remains constant.
Bref résumé de l'invention Brief summary of the invention
[0012] Un but de la présente invention est de proposer un mouvement de montre à tourbillon à un seul axe exempt des limitations des An object of the present invention is to provide a single-axis tourbillon watch movement free of the limitations of the
mouvements connus. known movements.
[0013] Un autre but de l'invention est de proposer un mouvement de montre à tourbillon différent des mouvements existants. Another object of the invention is to provide a tourbillon watch movement different from existing movements.
[0014] Un autre but de l'invention est de proposer un mouvement de montre à tourbillon à un seul axe plus précis que les mouvements de montre à tourbillon à un seul axe connus. Another object of the invention is to provide a single-axis tourbillon watch movement more accurate than the single-axis tourbillon watch movements known.
[0015] Un autre but de l'invention est de proposer un mouvement de montre à tourbillon dans lequel le déplacement de l'organe réglant crée une animation intéressante pour l'observateur. Another object of the invention is to provide a tourbillon watch movement in which the movement of the regulating member creates an interesting animation for the observer.
[0016] Selon l'invention, ces buts sont atteints notamment au moyen d'un mouvement de montre à tourbillon à un seul axe comportant : According to the invention, these objects are achieved in particular by means of a single-axis tourbillon watch movement comprising:
une platine ;  a platinum;
une roue fixe inclinée par rapport à la platine ;  a fixed wheel inclined relative to the plate;
une cage de tourbillon montée en biais autour de son axe de rotation qui est perpendiculaire à la roue fixe et incliné par rapport à la platine ;  a tourbillon cage mounted obliquely about its axis of rotation which is perpendicular to the fixed wheel and inclined relative to the platen;
un ensemble balancier - spiral monté sur un arbre de balancier perpendiculaire à la cage,  a pendulum-balance assembly mounted on a balance shaft perpendicular to the cage,
en sorte que l'inclinaison de l'ensemble balancier-spiral par rapport à la platine change lors de la rotation de la cage. [0017] Chaque point de la cage et du spiral parcourt une trajectoire circulaire dans un plan incliné par rapport à la platine et par rapport à la roue fixe. [0018] Cette solution permet à la fois de varier l'inclinaison du spiral par rapport à la platine, et de varier l'angle entre le plan du spiral et l'axe de rotation de la cage. Il en résulte un meilleur moyennage de la marche. so that the inclination of the sprung-balance assembly relative to the plate changes during the rotation of the cage. Each point of the cage and the spiral runs a circular path in a plane inclined relative to the plate and relative to the fixed wheel. This solution allows both to vary the inclination of the hairspring relative to the plate, and to vary the angle between the plane of the hairspring and the axis of rotation of the cage. This results in a better averaging of walking.
[0019] Afin de minimiser l'épaisseur du mouvement, la platine peut comporter une ouverture dans laquelle la roue fixe est logée au moins partiellement de manière inclinée par rapport à l'axe de l'ouverture. In order to minimize the thickness of the movement, the plate may comprise an opening in which the fixed wheel is housed at least partially inclined with respect to the axis of the opening.
L'ouverture peut traverser la platine. The opening can cross the stage.
[0020] Dans un mode de réalisation, la roue fixe est inclinée de 45° par rapport à la platine. L'angle entre la cage et l'axe de rotation de la cage est de 45°. Dans cette configuration, l'arbre de balancier passe à chaque tour par une position parallèle à la platine et par une position perpendiculaire à la platine. Il en résulte un excellent moyennage puisque le spiral passe chaque minute par une position horizontale et par une position verticale. Par ailleurs, il en résulte une animation intéressante du mouvement qui permet à la fois de bien observer le spiral et de contempler une trajectoire non triviale de l'organe réglant. In one embodiment, the fixed wheel is inclined 45 ° relative to the plate. The angle between the cage and the axis of rotation of the cage is 45 °. In this configuration, the balance shaft passes each turn by a position parallel to the plate and a position perpendicular to the plate. This results in an excellent averaging since the hairspring passes every minute by a horizontal position and by a vertical position. Moreover, the result is an interesting animation of the movement that allows both to observe the hairspring and to contemplate a nontrivial trajectory of the regulating organ.
[0021] Le tourbillon est avantageusement un tourbillon volant. Un tel tourbillon volant présente une cage montée sans pont de support, ce qui donne l'impression qu'elle flotte dans l'air, sans être maintenue. [0022] La cage du tourbillon peut comporter deux planches. Cet arrangement permet de bien observer le spiral et le balancier. The vortex is advantageously a flying tourbillon. Such a flying tourbillon has a cage mounted without a support bridge, which gives the impression that it floats in the air, without being maintained. The tourbillon cage may comprise two boards. This arrangement makes it possible to observe well the balance spring and the balance.

Exemple(s) de mode de réalisation de l'invention Example (s) of embodiment of the invention
[0030] Le mouvement de montre 1 illustré sur les figures comporte un organe réglant 2 monté sur une platine 3. L'heure est affichée au moyen d'aiguilles 6 devant un cadran 5, ici un petit cadran excentré. La référence 4 désigne de manière générale le rouage entre le barillet (non représenté), l'organe réglant 2 et les aiguilles 6. The watch movement 1 illustrated in the figures comprises a regulating member 2 mounted on a plate 3. The time is displayed by means of hands 6 in front of a dial 5, here a small eccentric dial. The reference 4 generally designates the work train between the barrel (not shown), the regulating member 2 and the needles 6.
[0031] L'organe réglant comporte un tourbillon avec une roue fixe 12, ici une roue de seconde munie d'une denture interne conique 120. La roue fixe est inclinée par rapport à la platine 3, dans cet exemple de 45°. Elle est logée partiellement dans une ouverture 30 traversant la platine. Comme on le voit notamment sur la figure 1 B, la roue fixe 12 dépasse au-dessous et au-dessus de la platine 3. L'impact sur l'épaisseur totale du mouvement est réduit grâce à cette ouverture 30. The regulating member comprises a vortex with a fixed wheel 12, here a second wheel provided with a conical inner toothing 120. The fixed wheel is inclined relative to the plate 3, in this example of 45 °. It is partially housed in an opening 30 crossing the plate. As can be seen in particular in FIG. 1B, the fixed wheel 12 protrudes below and above the plate 3. The impact on the total thickness of the movement is reduced by this opening 30.
[0032] Dans l'exemple illustré, la cage du tourbillon, formée par les deux planches 10 et 18, effectue un tour par minute. Des tourbillons tournant à une vitesse différente ou de manière discontinue peuvent aussi être imaginés dans le cadre de l'invention. [0033] Le mouvement de montre 1 illustré sur les figures comporte une seule cage 10, 18. Cette unique cage 10, 18 permet le support de l'ensemble balancier-spiral. In the illustrated example, the vortex cage, formed by the two boards 10 and 18, performs one revolution per minute. Vortices rotating at a different speed or discontinuously can also be imagined within the scope of the invention. The watch movement 1 illustrated in the figures comprises a single cage 10, 18. This single cage 10, 18 allows the support of the sprung balance assembly.
[0034] L'organe réglant comporte notamment un spiral 9 et un The regulating member comprises in particular a spiral 9 and a
balancier 8 monté sur un arbre de balancier 13 perpendiculaire aux deux planches 10, 18 de la cage. Le plan du spiral et le plan du balancier sont donc parallèles aux deux planches 10, 18 et pivotent avec la cage. Ainsi, on dispose d'une seule cage en rotation autour de l'ensemble balancier-spiral et on évite le coût et la complexité d'un mécanisme à double ou triple cage. [0035] La planche supérieure 10 n'est pas appuyée ; le tourbillon est donc un tourbillon volant. balance 8 mounted on a balance shaft 13 perpendicular to the two boards 10, 18 of the cage. The spiral plane and the balance plane are therefore parallel to the two boards 10, 18 and pivot with the cage. Thus, there is a single cage in rotation around the sprung-balance assembly and avoids the cost and complexity of a double or triple cage mechanism. The upper board 10 is not supported; the whirlwind is a flying whirlwind.
[0036] Un échappement comportant une roue d'échappement 15 et une ancre 17 est également monté dans la cage 10, 18. La roue d'échappement 15 est montée sur un arbre de roue d'échappement 14 perpendiculaire aux deux planches 10, 18 de la cage. Le plan de la roue d'échappement et le plan de l'ancre sont donc également parallèles aux deux planches 10, 18 et pivotent avec la cage. An escapement comprising an escape wheel 15 and an anchor 17 is also mounted in the cage 10, 18. The escape wheel 15 is mounted on an exhaust wheel shaft 14 perpendicular to the two boards 10, 18 of the cage. The plane of the escape wheel and the plane of the anchor are therefore also parallel to the two boards 10, 18 and pivot with the cage.
[0037] Les planches 10, 18 sont inclinées par rapport à la roue fixe 12. Dans l'exemple, l'angle d'inclinaison est de 45°. Elles tournent autour d'un axe géométrique a perpendiculaire à la roue fixe 12 et passant par le centre de cette roue fixe. Les planches 10, 18 ainsi que le spiral 9, le balancier 8 et les organes de l'échappement passent donc d'une position parallèle à la platine 3, telle qu'illustrée sur les figures 1A à 1 C, à une position The boards 10, 18 are inclined relative to the fixed wheel 12. In the example, the angle of inclination is 45 °. They rotate around a geometric axis a perpendicular to the fixed wheel 12 and passing through the center of this fixed wheel. The boards 10, 18 and the hairspring 9, the rocker 8 and the bodies of the exhaust therefore pass from a position parallel to the plate 3, as illustrated in FIGS. 1A to 1C, at a position
perpendiculaire à cette platine et illustrée sur les figures 2A à 2C, en passant par toutes les positions intermédiaires. La référence a désigne l'angle entre l'axe de rotation a de la cage et le plan du spiral ; cet angle passe de 135° dans la position de la figure 1 à 45° sur la position de la figure 2. Chaque point du spiral parcourt donc chaque minute un cercle autour de l'axe a. [0038] Un pignon conique 16 sur l'arbre de la roue d'échappement engrène avec la roue fixe 12 et met ainsi l'ensemble de la cage 10, 18 et des composants portés par cette cage en rotation. perpendicular to this plate and illustrated in Figures 2A to 2C, passing through all the intermediate positions. The reference a designates the angle between the axis of rotation a of the cage and the plane of the spiral; this angle goes from 135 ° in the position of FIG. 1 at 45 ° to the position of FIG. 2. Each point of the spiral therefore travels every minute a circle around the axis a. A bevel gear 16 on the shaft of the escape wheel meshes with the fixed wheel 12 and thus puts the assembly of the cage 10, 18 and components carried by this cage in rotation.
[0039] L'échappement est entraîné par le rouage 4 au travers d'un arbre non représenté, parallèle aux arbres 13 et 14 et dont l'extrémité inférieure est munie d'un pignon conique non représenté et coaxial avec la roue fixe 12. The exhaust is driven by the gear 4 through a shaft not shown, parallel to the shafts 13 and 14 and whose lower end is provided with a conical gear not shown and coaxial with the fixed wheel 12.
