Description

Mouvement horloger comprenant un système de guidage flexible  Watch movement comprising a flexible guiding system
La présente invention concerne un mouvement horloger, notamment pour montre-bracelet, comprenant un système de guidage flexible. The present invention relates to a watch movement, in particular for a wristwatch, comprising a flexible guiding system.
Les systèmes de guidage flexible sont conçus pour permettre le déplacement d'un composant dans une direction déterminée en rotation ou en translation sans frottements. Ces systèmes comprennent des parties élastiques de guidage qui relient une partie mobile, constituant ledit composant, à une partie de fixation servant à fixer le système de guidage flexible sur un support tel que la platine d'un mouvement horloger. Des exemples de tels systèmes sont décrits dans les documents EP 2037335, EP 2273323 et WO 201 1/120180. Ils présentent tous l'inconvénient d'occuper une place importante dans le mouvement, notamment en hauteur.  The flexible guide systems are designed to allow the displacement of a component in a determined direction in rotation or translation without friction. These systems include resilient guide portions which connect a movable portion, constituting said component, to an attachment portion for securing the flexible guide system to a support such as the turntable of a watch movement. Examples of such systems are described in EP 2037335, EP 2273323 and WO 201 1/120180. They all have the disadvantage of occupying an important place in the movement, especially in height.
La présente invention vise à remédier à cet inconvénient, ou au moins à l'atténuer, et propose à cette fin un mouvement horloger comprenant un bâti et un mécanisme monté dans ou sur le bâti, le mécanisme comprenant un système de guidage flexible comprenant une partie de fixation et une partie mobile reliées par des parties élastiques de guidage, caractérisé en ce que le système de guidage flexible est situé en partie au moins dans une ouverture d'un élément du bâti et est fixé par la partie de fixation à la paroi latérale de ladite ouverture.  The present invention aims to overcome this drawback, or at least to mitigate it, and proposes for this purpose a watch movement comprising a frame and a mechanism mounted in or on the frame, the mechanism comprising a flexible guide system comprising a part for fixing and a moving part connected by elastic guide parts, characterized in that the flexible guide system is located partly in an opening of a frame member and is fixed by the fastening part to the side wall of said opening.
Par définition, la partie de fixation et la partie mobile sont plus rigides, ou comportent une partie plus rigide, que les parties élastiques.  By definition, the attachment portion and the movable portion are stiffer, or have a more rigid portion, than the resilient portions.
Le mécanisme comprend tout ou partie des composants mobiles du mouvement. Il peut comprendre plusieurs dits systèmes de guidage flexible pour guider plusieurs composants.  The mechanism includes all or part of the moving components of the movement. It can include several so-called flexible guidance systems to guide multiple components.
Le bâti peut être le bâti fixe du mouvement ou un bâti mobile monté sur le bâti fixe et portant le mécanisme.  The frame may be the fixed frame of the movement or a movable frame mounted on the fixed frame and carrying the mechanism.
Avantageusement, le système de guidage flexible est fixé à la paroi latérale de ladite ouverture par une déformation élastique de la partie de fixation, déformation qui peut être purement élastique ou qui peut être une composante élastique d'une déformation plastique et élastique (chassage). Advantageously, the flexible guiding system is fixed to the side wall of said opening by elastic deformation of the fixing part, deformation which may be purely elastic or which may be an elastic component of a plastic and elastic deformation (hunting).
La partie de fixation peut comprendre une première partie annulaire reliée à la partie mobile par les parties élastiques de guidage et une deuxième partie annulaire entourant la première partie annulaire et reliée à cette dernière par des parties de liaison discrètes.  The fixing portion may comprise a first annular portion connected to the movable portion by the elastic guide portions and a second annular portion surrounding the first annular portion and connected thereto by discrete connecting portions.
En variante, la partie de fixation peut comprendre une première partie reliée à la partie mobile par les parties élastiques de guidage et des bras élastiques reliant la paroi latérale de ladite ouverture à la première partie.  Alternatively, the attachment portion may comprise a first portion connected to the movable portion by the resilient guide portions and resilient arms connecting the side wall of said opening to the first portion.
Ledit élément du bâti peut être une platine ou un pont.  Said element of the frame may be a plate or a bridge.
Ladite ouverture peut être circulaire et/ou traversante.  Said opening may be circular and / or through.
Typiquement, la partie de fixation entoure la partie mobile.  Typically, the attachment portion surrounds the movable portion.
De préférence, le système de guidage flexible est monolithique.  Preferably, the flexible guide system is monolithic.
Le mécanisme peut comprendre un composant solidaire de la partie mobile et situé hors de l'ouverture.  The mechanism may comprise a component integral with the movable portion and located outside the opening.
Un tel composant peut être un balancier, une ancre d'échappement, un levier ou une bascule par exemple.  Such a component may be a rocker, an escapement anchor, a lever or a rocker for example.
En particulier, le composant peut être une bascule d'embrayage portant une roue d'embrayage.  In particular, the component may be a clutch rocker carrying a clutch wheel.
D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description détaillée suivante faite en référence aux dessins annexés dans lesquels :  Other features and advantages of the present invention will appear on reading the following detailed description given with reference to the accompanying drawings in which:

En référence à la figure 1 , un système de guidage flexible selon un premier mode de réalisation de l'invention comprend une partie de fixation 1 et une partie mobile 2 reliées par des lames élastiques 3. Dans l'exemple représenté, les lames élastiques 3 sont du type « lames croisées non séparées » et se croisent ainsi physiquement en un point 4. Les lames élastiques 3 forment un pivot flexible permettant à la partie mobile 2 d'être guidée sans frottements en rotation autour du point 4. La partie de fixation 1 , la partie mobile 2 et les lames élastiques 3 sont coplanaires. La partie de fixation 1 présente une forme annulaire qui entoure la partie mobile 2. Une protubérance radiale 1 a située sur la face intérieure de la partie de fixation 1 sert de butée à des surfaces 2a de la partie mobile 2 pour limiter le débattement angulaire de la partie mobile 2 par rapport à la partie de fixation 1 .  Referring to Figure 1, a flexible guide system according to a first embodiment of the invention comprises a fixing portion 1 and a movable portion 2 connected by resilient blades 3. In the example shown, the elastic blades 3 are of the type "crossed blades not separated" and thus physically intersect at a point 4. The resilient blades 3 form a flexible pivot allowing the movable portion 2 to be guided without friction in rotation about the point 4. The fixing portion 1, the movable portion 2 and the elastic blades 3 are coplanar. The fixing portion 1 has an annular shape which surrounds the movable portion 2. A radial protuberance 1 a located on the inner face of the attachment portion 1 serves as a stop for surfaces 2a of the movable part 2 to limit the angular deflection of the movable part 2 with respect to the attachment part 1.
La partie de fixation 1 est chassée dans une ouverture 5 que présente la platine ou un pont 6 du bâti fixe d'un mouvement horloger. L'ouverture 5 est de préférence circulaire et traversante, comme illustré. A la figure 1 , la platine ou le pont 6 comportant l'ouverture 5 est représenté schématiquement sous la forme d'un anneau. Grâce à cet agencement, le système de guidage flexible 1 , 2, 3 est intégré au bâti fixe du mouvement et libère de la place pour les autres composants mobiles du mouvement, notamment en hauteur. De plus, une grande liberté est offerte pour le placement du système de guidage flexible 1 , 2, 3 dans le mouvement, puisqu'il suffit de prévoir une ouverture dans la platine ou un pont et d'y introduire le système de guidage flexible 1 , 2, 3. Il va de soi que ce principe peut aussi être appliqué à un bâti mobile du mouvement monté sur le bâti fixe, par exemple à une cage de tourbillon. The fixing portion 1 is driven into an opening 5 which the platen or a bridge 6 of the fixed frame of a watch movement. The opening 5 is preferably circular and through, as illustrated. In Figure 1, the plate or the bridge 6 having the opening 5 is shown schematically in the form of a ring. With this arrangement, the flexible guide system 1, 2, 3 is integrated with the fixed frame of the movement and frees up space for the other mobile components of the movement, especially in height. In addition, great freedom is offered for the placement of the flexible guide system 1, 2, 3 in the movement, since it is sufficient to provide an opening in the plate or a bridge and to introduce the flexible guide system 1, 2, 3. It goes of course that this principle can also be applied to a moving frame of the movement mounted on the fixed frame, for example to a tourbillon cage.
La partie mobile 2 pourrait constituer un composant du mouvement, tel qu'un balancier. Dans l'exemple représenté, toutefois, la partie mobile 2 porte des moyens d'assemblage, par exemple des tétons ou goupilles 7, par lesquels un composant mobile du mouvement peut être rendu solidaire de la partie mobile 2. Ce composant mobile est alors situé hors de l'ouverture 5. Ce composant mobile est par exemple un levier ou bascule tel qu'une bascule d'embrayage 8 portant une roue d'embrayage 9 comme montré à la figure 2. Il pourrait, en variante, être un balancier ou une ancre d'échappement par exemple. A la figure 2, le mécanisme du mouvement dont fait partie le système de guidage flexible 1 , 2, 3 est représenté partiellement et désigné par le repère 20.  The moving part 2 could constitute a component of the movement, such as a pendulum. In the example shown, however, the movable portion 2 carries assembly means, for example pins or pins 7, by which a movable component of the movement can be secured to the movable part 2. This mobile component is then located 5. This mobile component is for example a lever or rocker such as a clutch rocker 8 carrying a clutch wheel 9 as shown in Figure 2. It could, alternatively, be a pendulum or an escape anchor for example. In FIG. 2, the movement mechanism of which the flexible guide system 1, 2, 3 is part is partially represented and designated by the reference 20.
Dans un deuxième mode de réalisation de l'invention, montré à la figure 3, des lumières 10 formées dans la partie de fixation 1 divisent cette dernière en deux parties annulaires concentriques 1 1 , 12 reliées l'une à l'autre par des parties de liaison discrètes 13. La partie annulaire extérieure 1 1 subit l'essentiel des contraintes de déformation pendant le chassage du système de guidage flexible 1 , 2, 3 dans l'ouverture 5 du bâti. La partie annulaire intérieure 12 est, elle, sensiblement isolée des contraintes de chassage par les lumières 10. Le point 4 de croisement des lames élastiques 3, autour duquel pivote la partie mobile 2, n'est ainsi sensiblement pas déplacé pendant le chassage, ce qui augmente la précision de fonctionnement du composant.  In a second embodiment of the invention, shown in FIG. 3, slots 10 formed in the fixing part 1 divide the latter into two concentric annular parts 11, 12 connected to one another by parts The outer annular portion 1 1 undergoes most of the deformation stresses during the driving of the flexible guide system 1, 2, 3 in the opening 5 of the frame. The inner annular portion 12 is, itself, substantially isolated from the driving stresses by the lights 10. The point 4 of crossing the elastic strips 3, around which the movable part 2 pivots, is thus not substantially displaced during the driving, this which increases the operating accuracy of the component.
Dans un troisième mode de réalisation de l'invention, montré à la figure 4, la partie de fixation 1 comprend une partie annulaire intérieure 14 qui entoure la partie mobile 2 et est reliée à cette dernière par les lames élastiques 3, et des bras élastiques extérieurs 15 qui sont reliés à la partie annulaire intérieure 14 par une partie de liaison 16. Les bras élastiques 15 sont en contact avec la paroi latérale 5a de l'ouverture 5 et maintiennent le système de guidage flexible 1 , 2, 3 dans l'ouverture 5 par leur déformation élastique. A la différence des premier et deuxième modes de réalisation (figures 1 et 3) où le système de guidage flexible 1 , 2, 3 est entré à force dans l'ouverture 5 et où la partie de fixation 1 subit une déformation élastique et plastique, la composante élastique de la déformation assurant le maintien du système 1 , 2, 3 dans l'ouverture 5, le système de guidage flexible 1 , 2, 3 selon le troisième mode de réalisation (figure 4) peut être fixé à la paroi latérale 5a de l'ouverture 5 en rapprochant les bras élastiques 15 l'un de l'autre, en étant ensuite introduit dans l'ouverture 5 puis en relâchant les bras élastiques 15 pour qu'ils exercent des contraintes contre la paroi latérale 5a de l'ouverture 5. In a third embodiment of the invention, shown in FIG. 4, the fixing part 1 comprises an inner annular portion 14 which surrounds the movable part 2 and is connected to the latter by the elastic blades 3, and elastic arms 15 which are connected to the inner annular portion 14 by a connecting part 16. The elastic arms 15 are in contact with the side wall 5a of the opening 5 and maintain the flexible guide system 1, 2, 3 in the opening 5 by their elastic deformation. Unlike the first and second embodiments (Figures 1 and 3) where the flexible guide system 1, 2, 3 is forced into the opening 5 and the attachment portion 1 undergoes elastic and plastic deformation, the elastic component of the deformation ensuring the maintenance of the system 1, 2, 3 in the opening 5, the flexible guide system 1, 2, 3 according to the third embodiment (Figure 4) can be fixed to the side wall 5a the opening 5 by bringing the elastic arms 15 closer to one another, then being introduced into the opening 5 and then releasing the elastic arms 15 so that they exert stresses against the side wall 5a of the opening 5.
Le système de guidage flexible selon l'invention peut être réalisé de manière monolithique, par exemple en silicium ou en toute autre matière appropriée selon la technique de gravure ionique réactive profonde dite « DRIE » (Deep Reactive Ion Etching), en nickel, alliage de nickel ou toute autre matière appropriée selon la technique LIGA (lithographie, galvanoplastie, moulage), en acier, cuivre-béryllium, maillechort ou autre alliage métallique par fraisage ou par électroérosion, ou en verre métallique par moulage.  The flexible guidance system according to the invention can be produced monolithically, for example in silicon or in any other suitable material according to the technique of deep reactive ion etching (DRIE), in nickel, alloy of nickel or any other suitable material according to the LIGA technique (lithography, electroplating, molding), steel, copper-beryllium, nickel silver or other metal alloy by milling or electroerosion, or metal glass by molding.
Le système de guidage flexible selon l'invention pourrait définir un autre type de pivot flexible qu'un pivot à lames croisées non séparées, par exemple un pivot à lames croisées séparées ou un pivot à centre de rotation déporté dit « RCC » (Remote Center Compliance). Le système de guidage flexible pourrait aussi, en variante, être un système de guidage linéaire.  The flexible guide system according to the invention could define another type of flexible pivot that a pivot with unseparated crossed blades, for example a pivot with separate crossed blades or a pivot with a remote center of rotation called "RCC" (Remote Center Compliance). The flexible guide system could also alternatively be a linear guide system.
Par ailleurs, la partie de fixation 1 pourrait être fixée à la paroi latérale 5a de l'ouverture 5 d'une autre manière que par chassage ou déformation purement élastique, par exemple par collage ou soudage.  Furthermore, the fastening portion 1 could be fixed to the side wall 5a of the opening 5 in another way that by driving or purely elastic deformation, for example by gluing or welding.
