Description

Les mécanismes de tourbillon pour pièces d'horlogerie ont été initialement conçus et réalisés pour stabiliser la marche du balancier en moyennant les effets de la gravitation sur le balourd du balancier. Aujourd'hui les balanciers sont bien équilibrés et surtout dans les montres-bracelets les variations de marche les plus importantes sont dues à des variations d'amplitude du balancier entre les positions horizontale (ou plate) et verticale (ou pendue) de celui-ci. En effet, l'amplitude des oscillations du balancier dépend des frottements de son axe dans ses pivots, frottements dont la valeur varie selon les positions de l'axe du balancier dans l'espace et notamment entre sa position verticale et sa position horizontale.The tourbillon mechanisms for timepieces were initially designed and made to stabilize the balance of the pendulum by means of the effects of gravitation on the pendulum balance. Today the balancers are well balanced and especially in wristwatches the most important variations of market are due to variations in amplitude of the balance between the horizontal (or flat) and vertical (or hanging) positions of it . Indeed, the amplitude of the oscillations of the pendulum depends on the friction of its axis in its pivots, friction whose value varies according to the positions of the axis of the balance in space and in particular between its vertical position and its horizontal position.

Pour tenter de réduire ou de moyenner les effets des forces de frottement qui agissent sur les pivots du balancier, de nouveaux systèmes de tourbillons multi-axiaux très complexes ont été évoqués dans lesquels le système réglant de la montre est amené à se déplacer dans un espace à plusieurs dimensions par rapport à un système de référence fixe. Par exemple, le brevet suisse CH 693.047 concerne une pièce d'horlogerie dans laquelle le système réglant est logé dans une cage qui fait des rotations autour d'un premier axe et d'un deuxième axe. D'une façon similaire, la demande de brevet EP 1465024A décrit un tourbillon bi-axial comprenant une première cage conventionnelle contenant le balancier et le pignon d'échappement, cette cage étant logée à l'intérieur d'une deuxième cage dont la rotation s'effectue autour d'un axe perpendiculaire à l'axe de rotation de la première cage. Cependant, ces mécanismes de tourbillon à deux rotations indépendantes du système réglant restent très complexes et onéreux pour l'horloger.In an attempt to reduce or moderate the effects of the friction forces acting on the pivots of the balance, new multi-axial vortex systems very complex have been discussed in which the control system of the watch is caused to move in a space multi-dimensional compared to a fixed reference system. For example, the Swiss patent CH 693.047 relates to a timepiece in which the regulating system is housed in a cage that rotates about a first axis and a second axis. In a similar way, the request for EP 1465024A describes a bi-axial vortex comprising a first conventional cage containing the balance and the escape pinion, this cage being housed inside a second cage whose rotation is carried out about an axis perpendicular to the axis of rotation of the first cage. However, these vortex mechanisms with two rotations independent of the regulating system remain very complex and expensive for the watchmaker.

Le tourbillon divulgué dans l'article " Etude comparative entre le tourbillon Breguet et le carrousel du Danois Bonniksen", publié dans le Jahrbuch der Deutschen Gesellschaft für Chronometrie, Stuttgart, vol. 47, 1996, pages 179-182 présente une seule cage perpendiculaire au plan du mouvement.The vortex disclosed in the article " Comparative study between the Breguet tourbillon and the carousel of the Danish Bonniksen ", published in the Jahrbuch der Deutschen Gesellschaft für Chronometrie, Stuttgart, 47, 1996, pages 179-182 presents a single cage perpendicular to the plane of the movement.

Par contre, pour compenser ce phénomène, appelé différence au "plat-pendu" et donc minimiser les écarts de marche et ceci de façon simple, la présente invention propose une pièce d'horlogerie comportant un tourbillon qui se distingue par le fait qu'il comporte une seule cage portant le balancier et tournant dans une direction seulement, et par le fait que l'axe de rotation du balancier forme un grand angle (c'est à dire un angle d'au moins 45°) avec l'axe de rotation de la cage, et ainsi fait la moyenne des marches dans les différentes positions au plat pendu. L'invention a pour objet une pièce d'horlogerie comportant un mouvement incorporant un mécanisme de tourbillon selon la revendication 1. En particulier, l'invention revêt des avantages importants quand cette pièce d'horlogerie est une montre bracelet car cette dernière prend différentes positions quand elle est portée au poignet.On the other hand, in order to compensate for this phenomenon, called the "flat-hung" difference and thus to minimize the differences in operation, and in a simple manner, the present invention proposes a timepiece comprising a tourbillon which distinguished by the fact that it comprises a single cage carrying the balance and rotating in one direction only, and in that the axis of rotation of the balance forms a wide angle (that is to say an angle of at least 45 °) with the axis of rotation of the cage, and so does the average steps in different positions hanging flat. The invention relates to a timepiece comprising a movement incorporating a tourbillon mechanism according to claim 1. In particular, the invention has significant advantages when this timepiece is a wristwatch because it takes different positions when it is worn on the wrist.

Dans une forme d'exécution l'axe de rotation de la cage du tourbillon forme un angle de 45° avec l'axe de la tige de remontoir de la pièce d'horlogerie.In one embodiment, the axis of rotation of the tourbillon cage forms an angle of 45 ° with the axis of the winding stem of the timepiece.

L'axe du balancier forme un grand angle d'au moins 45° avec l'axe de rotation de la cage. Cet angle, qui reste constant au cours du fonctionnement du mécanisme, est de préférence égal à 90° (ies deux axes étant perpendiculaires) ou sensiblement proche de 90°. Grâce à cet angle important entre l'axe du balancier et l'axe de rotation de la cage, un déplacement multidirectionnel du balancier et de ses pivots capable de compenser le phénomène du plat-pendu susmentionné est obtenu en utilisant une seule cage de rotation pour le tourbillon.The axis of the balance forms a wide angle of at least 45 ° with the axis of rotation of the cage. This angle, which remains constant during the operation of the mechanism, is preferably equal to 90 ° (the two axes being perpendicular) or substantially close to 90 °. Thanks to this important angle between the axis of the balance and the axis of rotation of the cage, a multidirectional movement of the balance and pivots capable of compensating for the phenomenon of the above-mentioned hangman is obtained by using a single rotating cage for the whirlwind.

L'axe de rotation de la cage du tourbillon forme un angle quelconque c'est-à-dire allant de 0° à 90° donc y compris les valeurs de 0° et 90° avec le plan du mouvement de la pièce d'horlogerie dans laquelle il est monté, mais cet angle est de préférence nul ou droit, soit parallèle ou perpendiculaire à ce plan du mouvement. Cet angle reste constant au cours du fonctionnement du mécanisme. Le mécanisme de tourbillon de la présente invention ne comporte qu'une seule cage.The axis of rotation of the tourbillon cage forms any angle, that is to say ranging from 0 ° to 90 °, thus including the values of 0 ° and 90 ° with the plane of movement of the timepiece. in which it is mounted, but this angle is preferably zero or straight, either parallel or perpendicular to this plane of movement. This angle remains constant during the operation of the mechanism. The vortex mechanism of the present invention has only one cage.

La figure unique du dessin annexé illustre schématiquement une coupe partielle d'une pièce d'horlogerie comportant un tourbillon agencé selon la présente invention.The single figure of the accompanying drawing schematically illustrates a partial section of a timepiece comprising a tourbillon arranged according to the present invention.

Comme on le voit au dessin, la pièce d'horlogerie selon l'invention comporte une platine inférieure 2 servant de support pour un pont 1 sur un côté et pour un cadran 3 sur l'autre côté. La platine 2 comporte deux jambes a,b s'étendant perpendiculairement au pont 1 et à la platine 2 dont l'extrémité de la jambe 2a prend appui sur la face supérieure du pont 1.As seen in the drawing, the timepiece according to the invention comprises a lower plate 2 serving as support for a bridge 1 on one side and for a dial 3 on the other side. The plate 2 comprises two legs a, b extending perpendicular to the bridge 1 and the plate 2, the end of the leg 2a bears on the upper face of the bridge 1.

L'extrémité de la jambe 2a comporte un alésage 4 recevant le moyeu 5 d'une roue fixe 6 présentant en coupe la forme d'une cloche, fixée au pont 2 à l'aide d'au moins une vis 7. La denture 8 de cette roue fixe 6 est située sur la tranche de la cloche et s'étend dans un plan perpendiculaire au cadran 3 et au pont 1.The end of the leg 2a has a bore 4 receiving the hub 5 of a fixed wheel 6 having in section the shape of a bell, fixed to the bridge 2 with the aid of at least one screw 7. The toothing 8 of this fixed wheel 6 is located on the edge of the bell and extends in a plane perpendicular to the dial 3 and the bridge 1.

Le moyeu 5 de cette roue fixe 6 est lui-même muni d'un alésage 9 dans lequel est logé un premier palier 10 formé d'une pierre percée.The hub 5 of this fixed wheel 6 is itself provided with a bore 9 in which is housed a first bearing 10 formed of a pierced stone.

La seconde jambe 2b de ia platine 2 comporte à son extrémité un alésage 11 dans lequel est logé un second palier 12 également formé par une pierre percée.The second leg 2b of the plate 2 has at its end a bore 11 in which is housed a second bearing 12 also formed by a pierced stone.

Les trous des pierres formant les premier et second paliers 10,12 sont alignés et situés sur un axe X-X parallèle au cadran 3, à la platine 1 et donc au plan du mouvement de la pièce d'horlogerie. Cet axe X-X définit l'axe autour duquel tourne la cage du tourbillon et dans cette exécution l'angle qu'il forme avec le plan du mouvement est sensiblement égal à zéro. L'axe de rotation X-X de la cage se trouve donc dans un plan parallèle à la platine 2 et/ou au cadran 1 si le mouvement comporte un cadran, ce qui n'est pas nécessaire dans toutes les réalisations. L'angle que forme l'axe de rotation X-Xde la cage est donc nul par rapport au plan du mouvement dans cette exécution. Dans des variantes d'exécution du mécanisme cet axe X-X de rotation de la cage de tourbillon peut former un angle quelconque avec le plan du mouvement d'horlogerie dans lequel il est monté, mais cet angle reste toujours constant au cours du fonctionnement du mécanisme. Dans une variante particulière, cet angle entre l'axe x-x de la cage et le plan du mouvement peut être sensiblement égal à 90°.The holes of the stones forming the first and second bearings 10,12 are aligned and located on an axis XX parallel to the dial 3, to the plate 1 and thus to the plane of movement of the timepiece. This axis XX defines the axis around which the tourbillon cage rotates and in this embodiment the angle it forms with the plane of movement is substantially equal to zero. The axis of rotation XX of the cage is therefore in a plane parallel to the plate 2 and / or the dial 1 if the movement comprises a dial, which is not necessary in all embodiments. The angle formed by the axis of rotation X-X of the cage is therefore zero with respect to the plane of movement in this embodiment. In variant embodiments of the mechanism, this axis XX of rotation of the tourbillon cage may form any angle with the plane of the clockwork movement in which it is mounted, but this angle remains constant during operation of the mechanism. In a particular variant, this angle between the axis xx of the cage and the plane of movement may be substantially equal to 90 °.

Le tourbillon comporte un berceau 13 muni de deux tourillons 13a, 13b situés dans le prolongement l'un de l'autre et dont les extrémités sont pivotées dans les paliers 10,12 respectivement. La partie médiane de ce berceau porte le palier inférieur 14 du balancier spiral 15,16. Le palier supérieur 17 du balancier spiral 15,16 est porté par un pont intermédiaire de tourbillon 18 fixé sur le berceau 13.The vortex comprises a cradle 13 provided with two pins 13a, 13b located in the extension of one another and whose ends are pivoted in the bearings 10,12 respectively. The middle part of this cradle carries the lower bearing 14 of the balance spring 15,16. The upper bearing 17 of the balance spring 15, 16 is carried by an intermediate vortex bridge 18 fixed on the cradle 13.

L'ancre 19 et le mobile d'échappement 20, 21 sont pivotés entre le pont intermédiaire de tourbillon 18 et un pont supérieur de tourbillon 22 fixé sur le berceau 13 du tourbillon.The anchor 19 and the escapement 20, 21 are pivoted between the intermediate vortex bridge 18 and an upper vortex deck 22 fixed on the cradle 13 of the tourbillon.

Ainsi, dans l'exemple illustré, la cage du tourbillon est formée du berceau 13 et des ponts intermédiaires de tourbillon 18 et supérieur de tourbillon 22.Thus, in the illustrated example, the tourbillon cage is formed of the cradle 13 and the intermediate tourbillon 18 and vortex upper bridges 22.

Le mobile d'échappement 20,21 est formé par une roue d'échappement 20 coopérant avec les palettes de l'ancre 19 et par un pignon d'échappement 21 en prise avec la denture 8 de la roue fixe 6.The escapement 20,21 is formed by an escape wheel 20 cooperating with the pallets of the anchor 19 and by an escape pinion 21 in engagement with the toothing 8 of the fixed wheel 6.

Dans l'exemple illustré l'axe du balancier-spiral 15,16 est perpendiculaire à l'axe X-X de rotation de la cage du tourbillon mais dans des variantes cet axe du balancier-spiral 15,16 pourrait former un angle différent, mais tout de même grand ou important, c'est-à-dire que cet angle peut avoir une valeur de 45° à 90° avec cet axe X-X de rotation de la cage du tourbillon conformément à l'invention. Dans tous les cas, l'angle que forme l'axe du balancier-spiral, tant par rapport à l'axe de rotation X-X de la cage de tourbillon que par rapport au plan du mouvement d'horlogerie dans lequel le mécanisme est monté, reste constant au cours du fonctionnement du mécanisme.In the illustrated example, the axis of the sprung balance 15, 16 is perpendicular to the axis XX of rotation of the tourbillon cage, but in variants this axis of the sprung balance 15, 16 could form a different angle, but all similarly large or important, that is to say that this angle can have a value of 45 ° to 90 ° with this axis XX of rotation of the tourbillon cage according to the invention. In all cases, the angle formed by the axis of the sprung balance, both with respect to the axis of rotation XX of the tourbillon cage and with respect to the plane of the clockwork movement in which the mechanism is mounted, remains constant during the operation of the mechanism.

Le tourillon 13b du berceau 13 porte un pignon d'entraînement 23 en prise avec la denture 24 d'une roue d'entraînement 25 en forme de cloche solidaire d'un axe 26 pivoté entre la platine 2 et le pont 1 du mouvement d'horlogerie. Cet axe d'entraînement 26 porte une seconde roue 27 en prise avec le rouage de la pièce d'horlogerie.The trunnion 13b of the cradle 13 carries a driving pinion 23 engaged with the toothing 24 of a drive wheel 25 in the form of a bell integral with an axis 26 pivoted between the plate 2 and the bridge 1 of the movement of watchmaking. This axis drive 26 carries a second wheel 27 engaged with the wheel of the timepiece.

De manière à assurer un meilleur rendement des engrenages, la roue d'entraînement 25 et le pignon d'entraînement 23 présentent de préférence des dentures coniques. Il en est de même pour la roue fixe 6 coopérant avec le pignon d'échappement 21.In order to ensure a better performance of the gears, the drive wheel 25 and the drive gear 23 preferably have conical teeth. It is the same for the fixed wheel 6 cooperating with the exhaust pinion 21.

Dans une telle configuration, la cage 13, 18, 22 du tourbillon tourne autour d'un axe X-X formant un angle constant avec le plan du mouvement tandis que le balancier-spiral (ainsi que les pivots de ce dernier) oscille dans un plan qui forme un angle important par rapport à l'axe de rotation de la cage du tourbillon. De cette manière, les différences ou variations de marche dues au plat-pendu sont réduites puisque aussi bien dans une position horizontale de la pièce d'horlogerie que dans une position verticale de celle-ci, les écarts de marche du balancier-spiral dus au frictions dans ses paliers sont moyennés - le balancier-spiral n'oscillant jamais dans un plan constant. Cette compensation est la plus efficace dans le cas où l'axe de rotation du baiancier-spirai est sensiblement perpendiculaire à l'axe de rotation de la seule cage du tourbillon, ce qui permet le plus efficacement que l'axe de rotation du balancier-spiral se retrouve dans diverses positions spaciales pour chaque position de la pièce d'horlogerie lorsqu'elle est portée sur le poignet. Donc, par exemple, quand la cage du tourbillon tourne sur un axe parallèle au plan du mouvement de la pièce d'horlogerie le tourbillon passe sur la période de rotation par les positions successives CH-3H-CB-9H, où

  • CH = montre horizontale; face/cadran haut
  • 3H = montre verticale; face/cadran gauche
  • CB = montre horizontale; face/cadran bas
  • 9H = montre verticale; face/cadran droit.
ce qui apporte toutes les compensations au plat pendu d'une façon beaucoup moins compliquée que dans les tourbillons multi-axiaux se mouvant dans plusieurs dimensions décrits dans le passé. De plus, cette compensation est réalisée au moyen d'un mécanisme très simple.In such a configuration, the cage 13, 18, 22 of the vortex rotates about an axis XX forming a constant angle with the plane of movement while the sprung balance (and the pivots of the latter) oscillates in a plane which forms an important angle with respect to the axis of rotation of the vortex cage. In this way, the differences or variations of the walking due to the hangman are reduced since both in a horizontal position of the timepiece and in a vertical position thereof, the gimbal balance of the gimbal due to the Frictions in its bearings are averaged - the balance-spring never oscillating in a constant plane. This compensation is most effective in the case where the axis of rotation of the spiral balancer is substantially perpendicular to the axis of rotation of the single tourbillon cage, which most effectively allows the axis of rotation of the balance wheel. spiral is found in various spatial positions for each position of the timepiece when worn on the wrist. Thus, for example, when the tourbillon cage rotates on an axis parallel to the plane of movement of the timepiece, the vortex passes over the period of rotation by the successive positions CH-3H-CB-9H, where
  • CH = horizontal watch; face / dial up
  • 3H = vertical watch; face / left dial
  • CB = horizontal watch; face / dial bottom
  • 9H = vertical watch; face / right dial.
which brings all compensations to the dish hung in a much less complicated way than in multi-axial vortices moving in several dimensions described in the past. In addition, this compensation is achieved by means of a very simple mechanism.

Ce mécanisme de tourbillon peut être incorporé dans une pièce d'horlogerie comportant ou pas un cadran, ce cadran lorsqu'il existe est situé dans un plan parallèle au plan du mouvement de la pièce d'horlogerie.This tourbillon mechanism can be incorporated in a timepiece with or without a dial, this dial when it exists is located in a plane parallel to the plane of movement of the timepiece.
