L'invention concerne encore un mécanisme d'échappement comportant au moins un tel mécanisme de blocage intermittent.The invention also relates to an escape mechanism comprising at least one such intermittent locking mechanism.
L'invention concerne encore un mouvement d'horlogerie mécanique comportant au moins un tel mécanisme d'échappement.The invention further relates to a mechanical clockwork comprising at least one such escape mechanism.
L'invention concerne le domaine des mécanismes d'horlogerie, et plus particulièrement des mouvements intégrant des modules fonctionnels prêts à l'emploi. L'invention concerne en particulier la distribution d'énergie dans un mécanisme d'échappement.The invention relates to the field of watch mechanisms, and more particularly to movements incorporating ready-to-use functional modules. In particular, the invention relates to the distribution of energy in an exhaust mechanism.
L'utilisation d'ensembles modulaires permet la réalisation de familles de produits, utilisant une base commune, et chacun personnalisé par des options ou des fonctionnalités différentes, notamment des complications dans le cas d'un mouvement horloger mécanique.The use of modular assemblies allows the realization of product families, using a common base, and each customized by different options or functionalities, including complications in the case of a mechanical watch movement.
La conception de modules ou cassettes de très haute précision permet de combiner une production de grande série avec des produits de qualité.The design of modules or cassettes of very high precision makes it possible to combine mass production with quality products.
On connaît ainsi des sous-ensembles modulaires de mouvements horlogers, par les demandes de brevets
Toutefois, dans une réalisation classique, les modules ne permettent pas toujours la réduction du nombre de composants, qui puisse permettre à la fois un abaissement du coût de production, et une simplification de la gamme d'assemblage, permettant à du personnel de technicité moyenne d'assembler et régler les fonctions les plus complexes, comme l'est celle relative à la distribution d'énergie dans un mécanisme d'échappement.However, in a conventional embodiment, the modules do not always allow the reduction of the number of components, which can allow both a lowering of the cost of production, and a simplification of the range assembly, allowing average technical personnel to assemble and adjust the most complex functions, as is the one relating to the distribution of energy in an exhaust mechanism.
Aussi, l'invention se propose de fournir des modules à nombre de composants réduit, et d'assemblage et réglage de complexité moyenne.Also, the invention proposes to provide modules with reduced number of components, and assembly and adjustment of average complexity.
La présente invention utilise à cet effet les nouvelles technologies de fabrication de micro-composants, MEMS, « LIGA », lithographie, et similaires, pour optimiser la fabrication de tels modules, présentés ici comme des cassettes. Ces cassettes peuvent, selon le cas être assemblées entre elles de façon irréversible comme dans les deux demandes ci-dessus, ou bien être positionnées et assemblées de façon classique.The present invention uses for this purpose the new micro-component manufacturing technologies, MEMS, "LIGA", lithography, and the like, to optimize the manufacture of such modules, presented here as cassettes. These cassettes may, as the case may be assembled together irreversibly as in the two applications above, or be positioned and assembled in a conventional manner.
L'invention se propose de faciliter l'intégration facile, dans une construction modulaire, d'un mécanisme de blocage intermittent de mécanisme d'échappement, ou d'un mécanisme d'échappement complet.The invention proposes to facilitate the easy integration, in a modular construction, of an intermittent locking mechanism of exhaust mechanism, or of a complete exhaust mechanism.
A cet effet, l'invention concerne un mécanisme de blocage intermittent d'au moins une roue d'échappement, ledit mécanisme de blocage intermittent coopérant avec au moins un organe régulateur ou un balancier lequel est animé d'un mouvement alternatif sous l'action d'au moins un ressort-spiral ou un moyen de rappel élastique alternatif, ledit mécanisme de blocage intermittent étant pivoté dans au moins une platine inférieure, caractérisé en ce que ledit mécanisme de blocage intermittent forme un composant monobloc indémontable avec ladite platine inférieure.To this end, the invention relates to an intermittent locking mechanism of at least one escape wheel, said intermittent locking mechanism cooperating with at least one regulating member or a balance which is reciprocated under the action at least one spiral spring or a reciprocating elastic return means, said intermittent locking mechanism being pivoted in at least one lower plate, characterized in that said intermittent locking mechanism forms an integral component unbreakable with said lower plate.
Selon une caractéristique de l'invention, ledit mécanisme de blocage intermittent comporte au moins une ancre monobloc avec ladite platine à laquelle elle est reliée par des moyens de rappel élastique.According to a characteristic of the invention, said intermittent locking mechanism comprises at least one monoblock anchor with said plate to which it is connected by elastic return means.
Selon une caractéristique de l'invention, ladite ancre comporte une partie supérieure porteuse de palettes, de cornes et d'un dard, et qui est rapportée et fixée sur une partie inférieure laquelle est dans le plan de ladite platine à laquelle elle est reliée par des moyens de rappel élastique qui sont également dans le plan de ladite platine.According to one characteristic of the invention, said anchor comprises an upper part carrying pallets, horns and a dart, and which is attached and fixed on a lower part which is in the plane of said plate to which it is connected by resilient return means which are also in the plane of said platen.
L'invention concerne encore un mécanisme d'échappement comportant au moins un tel mécanisme de blocage intermittent.The invention also relates to an escape mechanism comprising at least one such intermittent locking mechanism.
L'invention concerne encore un mouvement d'horlogerie mécanique comportant au moins un tel mécanisme d'échappement.The invention further relates to a mechanical clockwork comprising at least one such escape mechanism.
Le fait de réaliser des composants monolithiques, et en particulier avec la platine ou les ponts, a l'avantage de diminuer le nombre de pièces, éviter les problèmes d'assemblage. L'invention bénéficie de la précision de réalisation de ces composants monolithiques (typiquement, les pièces sont par exemple réalisées en silicium et bénéficient donc d'une précision micrométrique).The fact of making monolithic components, and in particular with the plate or bridges, has the advantage of reducing the number of parts, avoid assembly problems. The invention benefits from the precision of realization of these monolithic components (typically, the parts are for example made of silicon and thus benefit from a micrometric precision).
La cassette monolithique a le principal avantage de garantir les entraxes et de former un mécanisme, en particulier un oscillateur dans une application préférée, prêt à l'emploi.The monolithic cassette has the main advantage of guaranteeing the distances and forming a mechanism, particularly an oscillator in a preferred application, ready to use.
L'invention intègre en particulier des guidages flexibles, dont les avantages sont :
- une précision garantie ;
- un niveau de frottements très réduit voire nul ;
- l'absence d'hystérèse dans les mouvements, du fait de l'absence de frottements ou du moins de leur niveau extrêmement réduit ;
- l'absence de lubrification ;
- l'absence de jeu ;
- l'absence d'usure.
- guaranteed accuracy;
- a level of friction very reduced or even zero;
- the absence of hysteresis in the movements, because of the absence of friction or at least of their extremely reduced level;
- lack of lubrication;
- the lack of play;
- the absence of wear.
Leur fabrication induit des limitations, notamment une course de déplacement limitée, des efforts de rappel faibles, et une charge limitée. Néanmoins ces limitations ne sont pas rédhibitoires pour nombre de fonctions horlogères, en particulier celles qui sont relatives à la régulation.Their manufacture induces limitations, including a limited displacement stroke, low return forces, and a limited load. However, these limitations are not prohibitive for many horological functions, particularly those relating to regulation.
Ces limitations sont très largement compensées par la haute précision des entraxes, le faible nombre de composants à réaliser et donc une complexité et une durée d'assemblage réduites. Une cassette selon l'invention présente un grand avantage industriel : le mécanisme, notamment un oscillateur, en cassette forme un composant prêt à monter dans un mouvement. Rien n'interdit, d'ailleurs, de concevoir un mouvement entier sous la forme d'une cassette selon l'invention.These limitations are largely offset by the high accuracy of the centers, the small number of components to achieve and therefore reduced complexity and assembly time. A cassette according to the invention has a great industrial advantage: the mechanism, in particular an oscillator, in a cassette forms a component ready to mount in a movement. Nothing prohibits, moreover, to design an entire movement in the form of a cassette according to the invention.

Ainsi, dans une réalisation particulière, au moins la platine 2 comporte un mécanisme réglable en position 80 comportant une structure rigide 81 porteuse (notamment constituée par la plaque de platine elle-même), par l'intermédiaire d'au moins une lame élastique 83, d'un composant réglable en position 82. Ce composant réglable 82 porte, ou bien l'ancre 61, ou un pied d'ancre 64, ou une partie inférieure d'ancre 63. Le mécanisme 80 comporte des moyens d'indexage 84 agencés pour coopérer avec des moyens d'indexage complémentaire 91 que comporte un mécanisme de réglage 90.

Ce mécanisme de verrouillage est étant lui aussi fixé élastiquement à la structure 81.The
Ainsi, avantageusement, au moins un composant monobloc indémontable 20 comporte un mécanisme réglable en position 80 comportant une structure rigide 81. Cette structure rigide 81, notamment la platine 2, porte, par l'intermédiaire d'au moins une lame élastique 83, un tel composant réglable en position 82 comportant des moyens d'indexage 84 agencés pour coopérer avec des moyens d'indexage complémentaire 91 que comporte un mécanisme de réglage 90, lesdits moyens d'indexage complémentaire 91 étant montés débrayables des moyens d'indexage 84 et étant blocables en position de coopération par un mécanisme bloqueur 94 fixé élastiquement à ladite structure 81, ledit mécanisme bloqueur 94 étant lui-même soumis à l'action d'un mécanisme de verrouillage 98 qui l'autorise à occuper, ou bien une position débrayée dans laquelle ledit mécanisme de réglage 90 est libre, ou bien une position embrayée dans laquelle ledit mécanisme bloqueur 94 entrave ledit mécanisme de réglage 90, ledit mécanisme de verrouillage 98 étant lui aussi fixé élastiquement à ladite structure 81.Thus, advantageously, at least one unmountable
Ce mécanisme combiné de réglage, blocage et verrouillage, est aussi applicable à une grande diversité d'applications : positionnement d'un palier, d'une butée, ou autre.This combination mechanism for adjusting, locking and locking is also applicable to a wide variety of applications: positioning a bearing, a stop, or other.
La conception de mécanismes 1 selon l'invention comportant des composants monobloc indémontables 20 permet, encore, d'optimiser les pivotements des différents mobiles, et, selon le besoin, d'en assurer le parallélisme, ou au contraire de déplacer au moins une extrémité d'un arbre de mobile pour modifier un réglage de façon micrométrique.The design of
L'action sur les points de pivotement permet, notamment, de régler les entraxes entre mobiles pour régler la pénétration des dentures ou/et levées. Le réglage de l'entraxe peut être réalisé de façon monolithique avec la platine ou le pont. Ce principe de réglage des entraxes est valable pour tous les entraxes dans un mouvement.The action on the pivot points allows, in particular, to adjust the distance between mobile to adjust the penetration of the teeth and / or lifted. Adjustment of the center distance can be achieved monolithically with the deck or bridge. This principle of adjustment of the distances is valid for all the distances in a movement.
Dans une réalisation avantageuse, du mécanisme de blocage intermittent 6 selon l'invention, la platine 2 est monobloc avec des butées de limitation de course du mécanisme de blocage intermittent 6. De façon générale, cette incorporation d'éléments de limitation, que ce soit dans la platine 2, le pont 3, ou un autre composant monobloc indémontable 20, est un avantage de l'invention.In an advantageous embodiment, the
De façon particulière, le composant monobloc indémontable 20 est réalisé en silicium, et les moyens de rappel élastique intrinsèques du composant monobloc indémontable 20 sont précontraints dans un état oxydé du silicium.In particular, the unbreakable
Dans une réalisation avantageuse, le mécanisme 1 est réalisé en silicium. Les points de pivotement sont définis, par exemple, par des gravures anisotropiques (KOH) dans un substrat silicium. Le gros avantage est le positionnement très précis des points de pivotement (entraxe, verticalité).In an advantageous embodiment, the
Les anti-chocs peuvent ainsi être partiellement ou totalement réalisés dans la platine: le ressort de l'antichoc peut être réalisé en commun avec la platine. Une des deux (ou les deux) pierres peut être réalisée en commun avec la platine. Le pivotement se fait alors directement dans le silicium. Les points de pivotements peuvent être réalisés directement dans le silicium avec des revêtements de surface du type DLC ou autre. Il n'y a donc plus de pierre, et les points de rotation sont positionnés très précisément.Anti-shock can thus be partially or completely made in the plate: the spring of the shock can be achieved in common with the plate. One of the two (or both) stones can be made in common with the plate. Pivoting is then done directly in the silicon. The pivot points can be made directly in silicon with surface coatings of the DLC or other type. So there is no more stone, and the rotation points are positioned very precisely.
Dans une réalisation particulière, le composant monobloc indémontable 20 comporte des éléments sécables, destinés à faciliter son assemblage dans un ensemble supérieur, il suffit de briser ensuite ces éléments sécables pour donner un ou plusieurs degrés de liberté à certains de ses constituants.In a particular embodiment, the unbreakable
Dans une réalisation avantageuse de la cassette 1 selon l'invention, le composant monobloc indémontable 20 est réalisé en matériau micro-usinable, ou en silicium, ou en silicium oxydé, et les moyens de rappel élastique intrinsèques du composant monobloc indémontable 20 sont précontraints dans un état oxydé du silicium. D'autres matériaux selon les technologies MEMS ou « LIGA » peuvent être mis en oeuvre. Le quartz, le DLC, des matériaux au moins partiellement amorphes, des verres métalliques, peuvent, et non limitativement, être utilisés pour ces applications.In an advantageous embodiment of the
Une structuration particulière de la platine 2, ou/et du pont 3, ou/et des composants monobloc indémontables 20, peut permettre de compenser les effets de la dilatation de ces éléments de structure, ou des composants du mécanisme de la cassette 1. Il est par exemple possible de réaliser la platine en silicium, puis de l'oxyder, afin de travailler en cohérence.A particular structuring of the
