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.

Arrière-plan de l'inventionBackground of the invention

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 EP2605087 et EP2605279 au nom de ETA SA. Les modules mécaniques décrits dans ces demandes sont pré-réglés et assemblés de façon irréversible pour garantir la pérennité de leurs réglages.Modular subsets of watch movements are thus known from patent applications. EP2605087 and EP2605279 in the name of ETA SA. The mechanical modules described in these applications are pre-set and assembled irreversibly to ensure the durability of their adjustments.

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 in the number of components, which can allow both a Lowering the cost of production, and simplifying the assembly range, allowing medium-sized technical personnel to assemble and adjust the most complex functions, as is the one relating to the distribution of energy in a mechanical mechanism. 'exhaust.

Le document WO 2011/120180 A1 au nom de ROLEX décrit un mécanisme de blocage pour roue dentée, comportant une ancre, une platine et des moyens de rappel élastique, qui constituent un ensemble monobloc plan, dans le plan d'une roue d'échappement.The document WO 2011/120180 A1 in the name of ROLEX describes a locking mechanism for a toothed wheel, comprising an anchor, a plate and elastic return means, which constitute a planar monoblock assembly, in the plane of an escape wheel.

Résumé de l'inventionSummary of the invention

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 ensemble horloger comportant une platine inférieure et 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 agencé pour être 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 agencé pour être pivoté dans au moins ldite platine inférieure, caractérisé en ce que ledit mécanisme de blocage intermittent forme un composant monobloc indémontable avec ladite platine inférieure, laquelle forme encore un composant monolithique avec un premier palier de ladite roue d'échappement et avec un deuxième palier de pivotement dudit organe régulateur ou dudit balancier, ledit premier palier et ledit deuxième palier étant distants d'un entraxe fixe, et ledit mécanisme de blocage intermittent pivotant autour d'un axe virtuel dont la position théorique est définie en référence aux positions dudit premier palier et dudit deuxième palier.For this purpose, the invention relates to a watch assembly comprising a lower plate and an intermittent locking mechanism of at least one escape wheel, said intermittent locking mechanism cooperating with at least one regulating member or a rocker which is arranged to being reciprocated under the action of at least one spiral spring or an alternative elastic return means, said intermittent locking mechanism being arranged to be pivoted in at least said lower platen, characterized in that said mechanism intermittent blocking device forms a single-piece component which can not be dismounted with said bottom plate, which forms a monolithic component with a first bearing of said escape wheel and with a second pivot bearing of said regulator member or of said balance, said first bearing and said second bearing being spaced apart from a fixed spacing, and said pivoting intermittent locking mechanism around a virtual axis whose position theoretical is defined with reference to the positions of said first step and said second step.

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 ensemble horloger.The invention also relates to an escapement mechanism comprising at least one such watch assembly.

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.
The invention integrates in particular flexible guides, the advantages of which are:
  • 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.

In particular, the invention relates to the distribution of energy in an exhaust mechanism.

L'invention concerne un mécanisme de blocage intermittent 6 d'au moins une roue d'échappement 5. Ce mécanisme de blocage intermittent coopère avec au moins un organe régulateur 4 ou un balancier 41, lequel est animé d'un mouvement alternatif sous l'action d'au moins un ressort-spiral ou un moyen de rappel élastique alternatif 7. Le mécanisme de blocage intermittent 6 est pivoté dans au moins une platine inférieure 2.The invention relates to an intermittent locking mechanism 6 of at least one escape wheel 5. This intermittent locking mechanism cooperates with at least one regulating member 4 or a rocker arm 41, which is reciprocated under the action of at least one spiral spring or an alternative elastic return means 7. The intermittent locking mechanism 6 is pivoted in at least one lower plate 2.

Selon l'invention, ce mécanisme de blocage intermittent 6 forme un composant monobloc indémontable 20 avec la platine inférieure 2.According to the invention, this intermittent locking mechanism 6 forms a single-piece component that can not be dismounted with the lower plate 2.

De préférence, cette platine inférieure 2 forme encore un composant monolithique avec un premier palier 51 d'une roue d'échappement 5 et avec un deuxième palier 52 de pivotement de cet organe régulateur 4 ou du balancier 41.Preferably, this bottom plate 2 still forms a monolithic component with a first bearing 51 of an escape wheel 5 and with a second bearing 52 of pivoting of this regulating member 4 or of the balance 41.

Ce premier palier 51 et ce deuxième palier 52 sont distants d'un entraxe fixe.This first bearing 51 and second bearing 52 are spaced apart by a fixed distance.

Et le mécanisme de blocage intermittent 6 pivote autour d'un axe virtuel 53, dont la position théorique est définie en référence aux positions du premier palier 51 et du deuxième palier 52.And the intermittent blocking mechanism 6 pivots around a virtual axis 53, whose theoretical position is defined with reference to the positions of the first bearing 51 and the second bearing 52.

De préférence, ce mécanisme de blocage intermittent 6 comporte au moins une ancre 61 monobloc avec la platine 2, à laquelle elle est reliée par des moyens de rappel élastique 65.Preferably, this intermittent locking mechanism 6 comprises at least one integral anchor 61 with the plate 2, to which it is connected by elastic return means 65.

Dans une variante particulière, cette ancre 61 comporte une partie supérieure 62 porteuse de palettes, de cornes et d'un dard, et qui est rapportée et fixée sur une partie inférieure 63 laquelle est dans le plan de la platine 2. La partie inférieure 63 est reliée à la platine 2 par des moyens de rappel élastique 65 qui sont également dans le plan de la platine 2, tel que visible sur la figure 3.In a particular variant, this anchor 61 comprises an upper portion 62 carrying pallets, horns and a stinger, and which is attached and fixed on a lower portion 63 which is in the plane of the plate 2. The lower part 63 is connected to the plate 2 by elastic return means 65 which are also in the plane of the plate 2, as visible on the figure 3 .

Sur la variante de la figure 3, l'ancre 61 est située entre la platine 2 et un pont 3, et comporte une partie supérieure 62 porteuse de palettes, de cornes et d'un dard en une ou plusieurs parties et qui est monobloc avec une partie inférieure 63 et s'étend au-dessus d'elle en direction du pont 3. Cette partie inférieure 63 est dans le plan de la platine 2, à laquelle elle est reliée par des moyens de rappel élastique 65 qui sont également dans le plan de la platine 2.On the variant of the figure 3 , the anchor 61 is located between the plate 2 and a bridge 3, and has an upper portion 62 carrying pallets, horns and a stinger in one or more parts and which is integral with a lower portion 63 and s' extends above it towards the bridge 3. This lower part 63 is in the plane of the plate 2, to which it is connected by elastic return means 65 which are also in the plane of the plate 2.

Dans la variante de la figure 2, l'ancre 61 comporte un pied 64 dans le plan de la platine 2, ainsi que ces moyens de rappel élastique intégrés 65 qui sont aussi dans le plan de la platine 2. De façon avantageuse, l'ancre 61 est monolithique avec des points de pivotements : sur cette figure 2, le composant représenté en grisé est réalisé de manière monolithique. L"ancre 61 est guidée sur des bras flexibles 65 reliés à un bâti/platine. De façon propre à l'invention, on ajoute, sur ce bâti/platine, des points de pivotements, en l'occurrence celui de la roue d'échappement et celui du balancier. Le gros avantage est que l'on définit très précisément les entraxes.In the variant of the figure 2 , the anchor 61 has a foot 64 in the plane of the plate 2, and these integrated elastic return means 65 which are also in the plane of the plate 2. Advantageously, the anchor 61 is monolithic with points of pivoting: on this figure 2 , the component shown in gray is made monolithically. The anchor 61 is guided on flexible arms 65 connected to a frame / plate In accordance with the invention, pivot points are added to this frame / plate, in this case that of the wheel of FIG. The big advantage is that the center distances are very precisely defined.

Et, tout en étant monolithique, ce composant se développe sur plusieurs niveaux : sur deux plans sensiblement parallèles pour la réalisation de cette figure 2. Les figures 3 à 5 illustrent également des composants monolithiques à plusieurs niveaux, avec trois niveaux pour la figure 5.And, while being monolithic, this component develops on several levels: on two substantially parallel planes for the realization of this figure 2 . The Figures 3 to 5 also illustrate multi-level monolithic components, with three levels for figure 5 .

Dans la variante de la figure 3, la partie supérieure 62 de l'ancre 61 est rapportée sur un tel pied 63, et cette partie supérieure 62 n'est pas monobloc avec ce pied 63.In the variant of the figure 3 , the upper portion 62 of the anchor 61 is attached to such a foot 63, and this upper portion 62 is not integral with the foot 63.

Dans la variante de la figure 4, l'ancre est dans le plan de la platine, et comporte des excroissances 62A et 62B telles que palettes et respectivement dard et cornes, à au moins un niveau supérieur.In the variant of the figure 4 , the anchor is in the plane of the plate, and has protrusions 62A and 62B such as paddles and respectively dard and horns, at least one upper level.

De façon avantageuse, ce composant monobloc indémontable 20 comporte des moyens de rappel élastique intrinsèques pour l'exécution d'une fonction de distribution d'énergie ou/et de régulation ou/et de rappel ou/et d'amortissement ou/et de verrouillage dans une position de réglage.Advantageously, this unbreakable integral component 20 comprises intrinsic elastic return means for the execution of a function of energy distribution and / or regulation and / or return and / or damping and / or locking in a setting position.

Dans un agencement particulier, avantageux pour la fonction d'une ancre dont le pivotement n'est pas uniforme, et qui ne transporte pas une quantité d'énergie uniforme, ces moyens de rappel élastique intrinsèques comportent au moins un élément flexible bistable ou multistable.In a particular arrangement, advantageous for the function of an anchor whose pivoting is not uniform, and which does not carry a uniform quantity of energy, these intrinsic elastic return means comprise at least one bistable or multistable flexible element.

La figure 6 illustre une variante où l'ancre 61 est pivotée à l'intérieur de l'emprise de la serge du balancier 41, et où, de préférence, la totalité de l'ancre évolue sous le balancier 41.The figure 6 illustrates a variant where the anchor 61 is pivoted inside the grip of the beam of the balance 41, and where, preferably, the entire anchor moves under the balance 41.

Pour l'ajustement et la mémorisation en position, notamment pour un pré-réglage, d'au moins un des composants fonctionnels que comporte le mécanisme 1, un tel composant fonctionnel, notamment l'ancre 61, ou un pied d'ancre 64, ou une partie inférieure d'ancre 63, ou autre, est réglable en position et est immobilisable dans une position pré-réglée par des moyens de verrouillage.For adjusting and storing, in particular for a pre-setting, at least one of the functional components that the mechanism 1 comprises, such a functional component, in particular the anchor 61, or an anchor foot 64, or a lower part of anchor 63, or other, is adjustable in position and is immobilizable in a pre-set position by locking means.

La figure 7 illustre un ensemble monolithique comportant des moyens de réglage en position d'un composant lui aussi intégré au mécanisme 1, ces moyens de réglage étant immobilisables en position par des moyens de blocage.The figure 7 illustrates a monolithic assembly comprising means for adjusting the position of a component also integrated in the mechanism 1, these adjustment means being immobilizable in position by locking means.

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. Ces moyens d'indexage complémentaire 91 sont montés débrayables des moyens d'indexage 84, et sont blocables en position de coopération par un mécanisme bloqueur 94 fixé élastiquement à la structure 81.Thus, in a particular embodiment, at least the plate 2 comprises an adjustable mechanism in position 80 comprising a rigid carrier structure 81 (in particular constituted by the platinum plate itself), by means of at least one resilient blade 83 , an adjustable component in position 82. This adjustable component 82 carries, or the anchor 61, or an anchor foot 64, or a lower anchor 63. The mechanism 80 comprises indexing means 84 arranged to cooperate with complementary indexing means 91 that comprises an adjustment mechanism 90. These complementary indexing means 91 are detachably mounted indexing means 84, and are lockable in the cooperation position by a locking mechanism 94 fixed elastically to the structure 81.

Le mécanisme bloqueur 94 est lui-même soumis à l'action d'un mécanisme de verrouillage 98 qui l'autorise à occuper, ou bien une position débrayée dans laquelle le mécanisme de réglage 90 est libre, ou bien une position embrayée dans laquelle le mécanisme bloqueur 94 entrave le mécanisme de réglage 90. Ce mécanisme de verrouillage est étant lui aussi fixé élastiquement à la structure 81.The locking mechanism 94 is itself subjected to the action of a locking mechanism 98 which allows it to occupy, or a disengaged position in which the adjustment mechanism 90 is free, or a position engaged in the locking mechanism 94 obstructs the adjustment mechanism 90. This locking mechanism is also fixed elastically to the structure 81.

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 structure81, 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 integral component 20 comprises an adjustable mechanism in position 80 comprising a rigid structure 81. This rigid structure 81, in particular the plate 2, carries, via at least one elastic blade 83, a such adjustable component in position 82 comprising indexing means 84 arranged to cooperate with complementary indexing means 91 that includes a setting mechanism 90, said complementary indexing means 91 being mounted disengageable indexing means 84 and being blockable in the position of cooperation by a locking mechanism 94 fixed elastically to said structure81, said locking mechanism 94 itself being subjected to the action of a locking mechanism 98 which allows it to occupy, or a disengaged position in which said adjustment mechanism 90 is free, or an engaged position in which said blocking mechanism 94 interferes with said mechanism of rotation. 90, said locking mechanism 98 also being resiliently fixed to said structure 81.

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 mechanisms 1 according to the invention comprising unmountable monoblock components 20 further makes it possible to optimize the pivoting of the various mobiles, and, as required, to ensure their parallelism, or conversely to move at least one end of a mobile shaft to modify a setting micrometrically.

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 intermittent blocking mechanism 6 according to the invention, the plate 2 is integral with stroke limiting stops of the intermittent locking mechanism 6. In general, this incorporation of limiting elements, whether in the plate 2, the bridge 3, or another integral component unbreakable 20, is an advantage of the invention.

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 integral component 20 is made of silicon, and the intrinsic elastic return means of the unbreakable integral component 20 are prestressed in an oxidized state of silicon.

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 mechanism 1 is made of silicon. The pivot points are defined, for example, by anisotropic etchings (KOH) in a silicon substrate. The big advantage is the very precise positioning of the pivot points (center distance, verticality).

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 integral component 20 comprises breakable elements, intended to facilitate assembly in an upper assembly, it is sufficient to then break these breakable elements to give one or more degrees of freedom to some of its constituents.

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 cassette 1 according to the invention, the unbreakable monobloc component 20 is made of micro-machinable material, or silicon, or oxidized silicon, and the intrinsic elastic return means of the unbreakable monobloc component 20 are prestressed in an oxidized state of silicon. Other materials according to MEMS or "LIGA" technologies can be implemented. Quartz, DLC, at least partially amorphous materials, metallic glasses, can, and not exclusively, be used for these applications.

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 plate 2, or / and the bridge 3, and / or unmountable monoblock components 20, may make it possible to compensate for the effects of the expansion of these structural elements, or of the components of the mechanism of the cassette 1. it is possible, for example, to make the silicon plate and then to oxidize it, in order to work coherently.

L'invention concerne encore un mécanisme d'échappement 200 comportant au moins un tel mécanisme de blocage intermittent 6.The invention also relates to an escape mechanism 200 comprising at least one such intermittent blocking mechanism 6.

Dans une réalisation particulière, seuls la roue d'échappement et le balancier sont des composants indépendants, le reste du mécanisme d'échappement 200 constituant un tel composant monobloc indémontable 20.In a particular embodiment, only the escape wheel and the rocker arm are independent components, the rest of the escapement mechanism 200 constituting such an unbreakable monoblock component 20.

L'invention concerne encore un mouvement d'horlogerie 100 mécanique comportant au moins un tel mécanisme d'échappement 200.The invention also relates to a mechanical clockwork movement 100 comprising at least one such escapement mechanism 200.
