Description

Pivot pour mécanisme d'horlogerie Domaine de l'invention  Pivot for timepiece mechanism Field of the invention
L'invention concerne un pivot pour mécanisme d'horlogerie, comportant un premier guidage de révolution pour le maintien radial d'un arbre dans une platine, et un deuxième guidage frontal pour la limitation axiale de l'extrémité dudit arbre, et comportant au moins un amortisseur de choc élastique agissant sur au moins ledit premier guidage de révolution ou/et ledit deuxième guidage frontal, où ledit au moins un amortisseur de choc élastique est réalisé de façon monobloc dans un matériau micro-usinable ou en silicium ou en quartz ou en diamant ou rubis ou corindon au moins avec un élément de structure autre que ledit premier guidage de révolution et ledit deuxième guidage frontal.  The invention relates to a pivot for a clockwork mechanism, comprising a first revolution guide for the radial retention of a shaft in a plate, and a second frontal guide for axially limiting the end of said shaft, and comprising at least an elastic shock absorber acting on at least said first revolution guide and / or said second frontal guide, wherein said at least one elastic shock absorber is made integrally in a micro-machinable material or in silicon or quartz or in diamond or ruby or corundum at least with a structural element other than said first revolution guide and said second frontal guidance.
L'invention concerne encore une platine d'horlogerie équipée d'au moins un tel pivot.  The invention also relates to a clock plate equipped with at least one such pivot.
L'invention concerne encore un mouvement d'horlogerie mécanique comportant au moins une telle platine.  The invention also relates to a mechanical clockwork comprising at least one such platinum.
L'invention concerne le domaine des mécanismes d'horlogerie, et plus particulièrement le pivotement des mobiles horlogers.  The invention relates to the field of watch mechanisms, and more particularly the pivoting of watchmakers.
Arrière-plan de l'invention Background of the invention
Le pivotage des mobiles d'horlogerie a une influence essentielle sur la qualité des mouvements. La confection des pivots est coûteuse, en termes de nombre et de coût des composants, de coûts d'usinage d'implantations réalisées avec une géométrie de haute précision, et le montage des pierres et dispositifs anti-chocs nécessite un soin particulier.  The pivoting of clockwork mobiles has a major influence on the quality of movements. The manufacture of pivots is expensive, in terms of the number and cost of components, the cost of machining implantations made with high precision geometry, and the mounting of stones and anti-shock devices requires special care.
Classiquement, un pivot pour le guidage en pivotement de l'extrémité d'un arbre comporte un cabochon logé dans un alésage ou un lamage de la platine, ce cabochon contenant, logées ensemble dans un chaton, une pierre de guidage radial de l'arbre et une pierre d'appui et de butée de l'extrémité axiale de cet arbre, et au moins un dispositif anti-chocs tel qu'un ressort de suspension des pierres ou du chaton. Les contraintes de lubrification imposent la présence d'un huilier dont la forme doit garantir la lubrification en toute position. Le document CH 700 496 B1 au nom de PATEK PHILIPPE décrit un palier antichoc avec des moyens élastiques agissant axialement sur un coussinet comportant un trou de réception de pivot, et des moyens de guidage, qui sont constitués par ces moyens élastiques, pour forcer le coussinet à ne se déplacer qu'axialement, à rencontre des moyens de rappel élastique. Conventionally, a pivot for the pivoting guidance of the end of a shaft comprises a cabochon housed in a bore or countersink of the plate, this cabochon containing, housed together in a kitten, a radial guide stone of the shaft and a bearing stone and abutment of the axial end of this shaft, and at least one anti-shock device such as a spring suspension stones or kitten.

Le fait de réaliser des composants monolithiques, et en particulier avec la platine, a l'avantage de diminuer le nombre de pièces, et d'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, has the advantage of reducing the number of parts, and to 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 platine monolithique intégrant les pivots a le principal avantage de garantir les entraxes et de former une base précise pour un mécanisme, en particulier un oscillateur dans une application préférée, prêt à l'emploi.  The monolithic turntable incorporating the pivots has the main advantage of guaranteeing the center distances and of forming a precise base for a mechanism, in particular an oscillator in a preferred application, ready for use.
L'invention intègre en particulier des guidages flexibles, dont les avantages sont :  The invention integrates in particular flexible guides, the advantages of which are:
- une précision garantie ; - un niveau de frottements très réduit voire nul ; - guaranteed accuracy; a level of friction that is very small or even nil;
- l'absence de lubrification ;  - lack of lubrication;
- l'absence de jeu ;  - the lack of play;
- l'absence d'usure.  - no 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, et, ici, les guidages des pierres à course limitée.  Their manufacture induces limitations, including a limited displacement stroke, low return forces, and a limited load. Nevertheless, these limitations are not prohibitive for many watch functions, in particular those relating to regulation, and here, the guides of limited-run stones.
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 platine comportant au moins un pivot selon l'invention présente ainsi un grand avantage industriel. Description sommaire des dessins  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 plate having at least one pivot according to the invention thus has a great industrial advantage. Brief description of the drawings

Description détaillée des modes de réalisation préférés Detailed Description of the Preferred Embodiments
L'invention concerne le domaine des mécanismes d'horlogerie, et plus particulièrement le pivotement des mobiles horlogers.  The invention relates to the field of watch mechanisms, and more particularly the pivoting of watchmakers.
L'invention concerne un pivot 45 pour mécanisme d'horlogerie, comportant un premier guidage de révolution 46 pour le maintien radial d'un arbre 47 dans une platine 2, et un deuxième guidage frontal 49 pour la limitation axiale de l'extrémité de l'arbre 47. Ce pivot 45 comporte au moins un amortisseur de choc élastique 48, qui agit sur au moins le premier guidage de révolution 46 ou/et le deuxième guidage frontal 49.  The invention relates to a pivot 45 for a clockwork mechanism, comprising a first revolution guide 46 for the radial retention of a shaft 47 in a plate 2, and a second frontal guide 49 for the axial limitation of the end of the rotor. 47. This pivot 45 comprises at least one elastic shock absorber 48, which acts on at least the first revolution guide 46 and / or the second frontal guidance 49.
Selon l'invention, dans un premier mode préféré de réalisation, cet au moins un amortisseur de choc élastique 48 est réalisé de façon monobloc, dans un matériau micro-usinable ou en silicium ou en quartz ou en diamant ou rubis ou corindon, au moins avec un élément de structure 451 autre que le premier guidage de révolution 46 et le deuxième guidage frontal 49.  According to the invention, in a first preferred embodiment, this at least one elastic shock absorber 48 is made in one piece, in a micro-machinable material or in silicon or quartz or diamond or ruby or corundum, at least with a structural element 451 other than the first revolution guide 46 and the second frontal guidance 49.
Cet élément de structure 451 peut notamment consister en une platine, un pont, un cabochon, ou autre.  This structural element 451 can in particular consist of a plate, a bridge, a cabochon, or other.
Selon l'invention, le pivot 45 comporte un premier niveau et un deuxième niveau superposés. Au premier niveau le premier guidage de révolution (46) est suspendu à l'élément de structure 451 par l'intermédiaire d'au moins un premier amortisseur pare-chocs 48A, et au deuxième niveau le deuxième guidage frontal 49 est suspendu à l'élément de structure 451 par l'intermédiaire d'au moins un deuxième amortisseur pare-chocs 48B.  According to the invention, the pivot 45 comprises a first level and a second superimposed level. At the first level the first revolution guide (46) is suspended from the structural element 451 via at least one first bumper damper 48A, and at the second level the second frontal guide 49 is suspended from the structural element 451 via at least one second bumper damper 48B.
L'invention couvre toutes les variantes résultant d'une exécution monobloc entre plusieurs des composants fonctionnels élémentaires d'un pivot.  The invention covers all the variants resulting from a one-piece execution between several of the elementary functional components of a pivot.
En particulier, par composants fonctionnels élémentaires, on entend :  In particular, by elementary functional components, we mean:
- le premier guidage de révolution 46, souvent constitué par une pierre percée dans le cas d'un pivot classique ; - dans le cas fréquent où la lubrification de l'arbre est nécessaire, un huilier constitué par l'espace délimité par le dos, en général concave, du premier guidage de révolution, et le deuxième guidage frontal 49 ; the first revolution guide 46, often constituted by a pierced stone in the case of a conventional pivot; - In the frequent case where the lubrication of the shaft is necessary, an oiler constituted by the space delimited by the back, generally concave, of the first revolution guide, and the second frontal guidance 49;
- le deuxième guidage frontal 49, en général une pierre avec une surface sensiblement plane ;  the second frontal guidance 49, generally a stone with a substantially flat surface;
- un chaton pour le maintien de chaque pierre, ou bien un chaton supérieur 26 pour le maintien du premier guidage de révolution 46 et un chaton inférieur 27 pour le maintien du deuxième guidage frontal 49, ou bien un chaton unique pour le maintien du premier guidage de révolution 46 et du deuxième guidage frontal 49 ensemble ;  a kitten for the maintenance of each stone, or an upper kitten 26 for the maintenance of the first guide of revolution 46 and a lower kitten 27 for the maintenance of the second frontal guidance 49, or a single kitten for the maintenance of the first guide revolution 46 and second frontal guidance 49 together;
- un élément de liaison éventuel, ou bien rigide, ou bien flexible : un premier élément de liaison 48C entre le premier guidage de révolution 46 et son chaton supérieur 26 d'une part, un deuxième élément de liaison 48D entre le deuxième guidage frontal 49 et son chaton inférieur 27 d'autre part ;  - An optional link element, or rigid or flexible: a first connecting element 48C between the first revolution guide 46 and its upper kitten 26 on the one hand, a second connecting element 48D between the second frontal guide 49 and his lower kitten 27 on the other hand;
- au moins un amortisseur de choc élastique 48, qui peut se décomposer en un premier amortisseur de choc supérieur 48A, et un deuxième amortisseur de choc inférieur 48B ;  at least one elastic shock absorber 48, which can decompose into a first upper shock absorber 48A, and a second lower shock absorber 48B;
- un cabochon éventuel 452, qui peut lui aussi être séparé en un premier cabochon supérieur et un deuxième cabochon inférieur ;  a possible cabochon 452, which can also be separated into a first upper cabochon and a second lower cabochon;
- la platine 2 dans laquelle est effectué le pivotement.  - The plate 2 in which is performed the pivoting.
On comprend que l'invention couvre un très grand nombre de combinaisons, selon que tout ou partie des composants traditionnels d'un pivot sont réalisées de façon monobloc avec d'autres, et, en particulier, avec la platine.  It is understood that the invention covers a very large number of combinations, according to whether all or part of the traditional components of a pivot are made integrally with others, and in particular with the plate.
En particulier, le pivot selon l'invention peut être réalisé en un ou plusieurs niveaux.  In particular, the pivot according to the invention can be made in one or more levels.
La figure 9 illustre une réalisation à un seul niveau, à un seul composant, où la platine 2 intègre directement un amortisseur de choc élastique 48 unique portant un bloc également unique, dont le profil est adapté pour constituer à la fois le premier guidage de révolution 46 et le deuxième guidage frontal 49.  FIG. 9 illustrates a single-level embodiment with a single component, in which the plate 2 directly integrates a single elastic shock absorber 48 bearing a unit that is also unique, whose profile is adapted to constitute both the first revolution guide 46 and the second frontal guidance 49.
Dans la mesure où, traditionnellement, le premier guidage de révolution 46 et le deuxième guidage frontal 49 sont constitués par des pierres séparées, on peut également concevoir une architecture à deux niveaux superposés, un premier niveau supérieur pour le support du premier guidage de révolution 46, et un deuxième niveau inférieur pour le support du deuxième guidage frontal 49, tel que visible sur les figures 2 à 6, illustrant des variantes non limitatives de l'invention. Une telle architecture à deux niveaux n'implique pas que ces deux niveaux soient séparés, des liens entre les deux niveaux peuvent être réalisés, par exemple par jonction du premier guidage de révolution 46 et du deuxième guidage frontal 49, ou du chaton supérieur 26 et du chaton inférieur 27, ou du premier élément de liaison 48C et du deuxième élément de liaison 48D, ou autre, puisque les jonctions peuvent aussi être réalisées entre des composants fonctionnels ne remplissant pas la même fonction sur chacun des niveaux. Since, traditionally, the first revolution guide 46 and the second frontal guidance 49 are constituted by separate stones, it is also conceivable to have a two-level architecture superimposed, a first upper level for supporting the first revolution guide. , and a second lower level for the support of the second frontal guidance 49, as visible in Figures 2 to 6, illustrating non-limiting variants of the invention. Such a two-level architecture does not imply that these two levels are separated, links between the two levels can be made, for example by joining the first revolution guide 46 and the second frontal guidance 49, or the upper kitten 26 and the lower kitten 27, or the first connecting element 48C and the second connecting element 48D, or other, since the junctions can also be made between functional components that do not perform the same function on each of the levels.
Bien sûr, il est également possible de concevoir un nombre de niveaux supérieur, mais on est vite limité par la complexité de réalisation en cas de fabrication de type MEMS, qui déjà n'autorise pas toutes les architectures dans une réalisation à deux niveaux superposés. On peut néanmoins fabriquer le composant avec le plan de silicium parallèle à l'axe.  Of course, it is also possible to design a higher number of levels, but it is quickly limited by the complexity of realization in the case of manufacturing type MEMS, which already does not allow all architectures in a realization on two levels superimposed. It is nevertheless possible to manufacture the component with the plane of silicon parallel to the axis.
La conception et la disposition de l'au moins un amortisseur de choc élastique 48, et de l'au moins un élément de liaison, dans sa réalisation sous forme flexible, permettent de les différencier en termes d'amortissement des accélérations radiales et axiales.  The design and arrangement of the at least one elastic shock absorber 48, and the at least one connecting element, in its embodiment in flexible form, allow to differentiate in terms of damping radial and axial accelerations.
La figure 10 illustre un exemple où le deuxième guidage frontal 49 est suspendu à un chaton inférieur 27 par un deuxième élément de liaison 48D flexible agencé pour encaisser un choc axial selon la direction de l'arbre 47, ce chaton inférieur 27 est fixé au chaton supérieur 26 qui porte aussi le premier guidage de révolution 46, et qui est suspendu à la platine 2 par un amortisseur de choc élastique 48 destiné à encaisser préférentiellement les chocs à composante radiale.  FIG. 10 illustrates an example where the second frontal guidance 49 is suspended from a lower kitten 27 by a second flexible connecting element 48D arranged to collect an axial impact in the direction of the shaft 47, this lower kitten 27 is fixed to the kitten upper 26 which also carries the first revolution guide 46, and which is suspended from the plate 2 by an elastic shock absorber 48 for preferentially receiving shocks radial component.
Naturellement, l'invention couvre aussi le cas où un ensemble pivot 450, de préférence monobloc, est logé dans un alésage ou un lamage d'une platine classique. Cet ensemble pivot 450 comporte alors au moins deux composants réalisés monobloc l'un avec l'autre, en matériau micro-usinable.  Naturally, the invention also covers the case where a pivot assembly 450, preferably monobloc, is housed in a bore or countersink of a conventional plate. This pivot assembly 450 then comprises at least two components produced in one piece with each other, made of micro-machinable material.
Dans un souci de simplification, la présente description n'illustre que quelques cas de pivot monobloc avec la platine, dans certaines architectures particulières, qui ne sont nullement limitatives.  For the sake of simplification, the present description illustrates only a few cases of pivot monoblock with the plate, in some particular architectures, which are not limiting.
Dans une réalisation particulière, le au moins un amortisseur de choc élastique 48 est réalisé de façon monobloc avec le deuxième guidage frontal 49. Dans une réalisation particulière, le au moins un amortisseur de choc élastique 48 est réalisé de façon monobloc avec le premier guidage de révolution 46. In a particular embodiment, the at least one elastic shock absorber 48 is made in one piece with the second frontal guidance 49. In a particular embodiment, the at least one elastic shock absorber 48 is made integrally with the first revolution guide 46.
Dans une réalisation combinée, le au moins un amortisseur de choc élastique 48 est réalisé de façon monobloc avec le deuxième guidage frontal 49 et avec le premier guidage de révolution 46.  In a combined embodiment, the at least one elastic shock absorber 48 is made in one piece with the second frontal guide 49 and with the first revolution guide 46.
Dans une réalisation particulière, le pivot 45 comporte un premier niveau et un deuxième niveau superposés. Au premier niveau le premier guidage de révolution 46 est suspendu à cet élément de structure 451 par l'intermédiaire d'au moins un premier amortisseur pare-chocs 48A. Et au deuxième niveau le deuxième guidage frontal 49 est suspendu à cet élément de structure 451 par l'intermédiaire d'au moins un deuxième amortisseur pare-chocs 48B.  In a particular embodiment, the pivot 45 comprises a first level and a second superimposed level.

Et, en particulier, ce premier guidage de révolution 46 ou ce deuxième guidage frontal 49 est réalisé de façon monobloc avec la platine 2. Naturellement, toutes les variantes décrites dans le premier mode de réalisation peuvent être combinées avec ce deuxième mode de réalisation. Dans ce deuxième mode, l'amortisseur de choc élastique peut être chassé ou soudé, de même que l'un des guidages de l'arbre, si les deux ne sont pas monobloc avec l'élément de structure, notamment la platine 2.  In a second embodiment of the invention, the pivot 45 for a clockwork mechanism, comprises a first revolution guide 46 for the radial retention of a shaft 47 in a plate 2, and a second frontal guide 49 for the limitation axial of the end of this shaft 47, and comprises at least one elastic shock absorber 48 acting on at least the first revolution guide 46 and / or the second frontal guide 49.

Une telle intégration d'éléments rapportés peut être nécessaire, dans les deux modes de réalisation, quand l'élément de structure porteur des composants du pivot n'est pas satisfaisant du point de vue des frottements. Ce qui n'empêche pas une fabrication monobloc, qui garantit la géométrie, et les caractéristiques de l'amortissement, du pivot considéré. L'invention concerne encore une platine 2 d'horlogerie comportant au moins un tel pivot 45. Such integration of inserts may be necessary, in both embodiments, when the bearing structural member of the pivot components is not satisfactory from the point of view of friction. This does not preclude a one-piece manufacture, which guarantees the geometry, and the characteristics of the damping, the pivot considered. The invention also relates to a watchmaking stage 2 comprising at least one such pivot 45.
Dans une réalisation particulière, la platine 2 forme l'élément de structure 451 pour au moins un pivot 45 qu'elle comporte.  In a particular embodiment, the plate 2 forms the structural element 451 for at least one pivot 45 that it comprises.

On a décrit ci-dessus une application préférée où à la fois le premier guidage de révolution 46 et le deuxième guidage frontal 49 sont portés par au moins un amortisseur de choc élastique 48, avec des variantes principales selon lesquelles :  A preferred application has been described above where both the first revolution guide 46 and the second frontal guide 49 are carried by at least one elastic shock absorber 48, with main variants according to which:

De façon plus générale, l'invention concerne aussi le cas où seul le premier guidage de révolution 46 ou le deuxième guidage frontal 49 est porté par au moins un amortisseur de choc élastique 48 qui lui est propre.  More generally, the invention also relates to the case where only the first revolution guide 46 or the second frontal guide 49 is carried by at least one resilient shock absorber 48 which is specific to it.
L'invention concerne encore un mouvement d'horlogerie 100 mécanique comportant au moins une telle platine 2.  The invention also relates to a mechanical clockwork movement 100 comprising at least one such plate 2.
L'invention concerne encore toutes les combinaisons d'intégration sous forme monobloc de plusieurs des composants traditionnels d'un pivot.  The invention also relates to all combinations of one-piece integration of several of the traditional components of a pivot.
L'invention concerne encore un ensemble pivot 450 destiné à être rapporté sur ou dans une platine, ledit ensemble pivot comportant au moins un premier guidage de révolution 46 pour le maintien radial d'un arbre 47 dans une platine 2 et un deuxième guidage frontal 49 pour la limitation axiale de l'extrémité de ce même arbre 47, et au moins un amortisseur de choc élastique 48. Selon l'invention, cet amortisseur de choc élastique 48 est réalisé de façon monobloc avec au moins l'une de ces portées. The invention also relates to a pivot assembly 450 intended to be mounted on or in a plate, said pivot assembly comprising at least a first revolution guide 46 for the radial retention of a shaft 47 in a plate 2 and a second frontal guide 49 for the axial limitation of the end of this same shaft 47, and at least one elastic shock absorber 48. According to the invention, this shock absorber 48 is integrally formed with at least one of these spans.
De façon préférée, l'amortisseur de choc élastique 48 est réalisé de façon monobloc avec à la fois le premier guidage de révolution 46 et le deuxième guidage frontal 49.  Preferably, the elastic shock absorber 48 is made in one piece with both the first revolution guide 46 and the second frontal guide 49.
L'interface entre l'ensemble pivot 450 et la platine 2 est constitué, ou bien par un cabochon 451 , ou bien par un amortisseur de choc élastique 81 comportant une surface de centrage 482 agencée pour coopérer avec un logement d'une platine 2.  The interface between the pivot assembly 450 and the plate 2 is constituted, either by a cabochon 451, or by an elastic shock absorber 81 having a centering surface 482 arranged to cooperate with a housing of a plate 2.
Un tel cabochon 451 renferme le premier guidage de révolution 46, le deuxième guidage frontal 49, et le au moins un amortisseur de choc élastique 48. De façon préférée, il est monobloc avec le au moins un amortisseur de choc élastique 48.  Such a cabochon 451 encloses the first revolution guide 46, the second frontal guide 49, and the at least one elastic shock absorber 48. Preferably, it is integral with the at least one elastic shock absorber 48.
L'invention concerne encore un mouvement d'horlogerie 100 mécanique comportant au moins une telle platine 2.  The invention also relates to a mechanical clockwork movement 100 comprising at least one such plate 2.
Dans un mode de réalisation particulier de l'invention, la platine inférieure 2 ou/et le pont supérieur 3, ou/et un cadre 17, forme un tel composant monobloc indémontable 20 avec au moins un palier antichocs pour la réception d'un pivot d'un composant d'un mécanisme incorporé dans une cassette 1 , notamment un mécanisme d'échappement.  In a particular embodiment of the invention, the lower plate 2 or / and the upper bridge 3, or / and a frame 17, forms such a non-removable integral component 20 with at least one anti-shock bearing for receiving a pivot a component of a mechanism incorporated in a cassette 1, in particular an escape mechanism.
Dans la réalisation particulière de la figure 1 , une cassette 1 comporte au moins un tel composant fonctionnel 10, tel un arbre 47, qui est mobile en pivotement entre un pivot inférieur 45 solidaire de la platine 2 et un pivot supérieur solidaire d'un pont non représenté, et au moins un tel pivot inférieur 45 ou supérieur 44 est réalisé de façon monobloc avec la platine 2 ou avec un pont et comporte une portée de révolution 46 pour le maintien radial d'un arbre 47 du composant fonctionnel 10 mobile en pivotement, et une portée frontale 49 pour la limitation axiale de l'extrémité de cet arbre 47. La portée de révolution 46 et la portée frontale 49 sont de préférence portées ensemble par un amortisseur de choc élastique 48 également monobloc avec elles.  In the particular embodiment of Figure 1, a cassette 1 comprises at least one such functional component 10, such as a shaft 47, which is pivotally movable between a lower pivot 45 secured to the plate 2 and an upper pivot secured to a bridge not shown, and at least one such lower pivot 45 or upper 44 is integrally formed with the plate 2 or with a bridge and has a revolution range 46 for the radial retention of a shaft 47 of the functional component 10 movable pivotally and a front surface 49 for the axial limitation of the end of this shaft 47. The revolution range 46 and the front span 49 are preferably carried together by an elastic shock absorber 48 also integral with them.
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. On peut réaliser de tels antichocs avec des pièces essentiellement bi-dimensionnelles en silicium ou similaire, avec le plan bi- dimensionnel perpendiculaire à l'axe, ou bien avec le plan bi-dimensionnel parallèle à l'axe. 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. Such shockproofing can be achieved with substantially two-dimensional silicon parts or the like, with the two-dimensional plane perpendicular to the axis, or with the two-dimensional plane parallel to the axis.
Dans une réalisation avantageuse, un composant monobloc indémontable tel qu'un pivot 45 ou un ensemble pivot 450, une platine 2 contenant l'un ou/et l'autre, est réalisé en silicium, et les moyens de rappel élastique intrinsèques de ce composant monobloc indémontable sont précontraints dans un état oxydé du silicium.  In an advantageous embodiment, a non-removable integral component such as a pivot 45 or a pivot assembly 450, a plate 2 containing one or / and the other, is made of silicon, and the intrinsic elastic return means of this component unbreakable monoblock are prestressed in an oxidized state of silicon.
Une structuration particulière de la platine 2, ou/et d'un pont, ou/et de tels composants monobloc indémontables, peut permettre de compenser les effets de la dilatation de ces éléments de structure, ou des composants du mécanisme. 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 a bridge, and / or such integral components unmountable, can compensate for the effects of the expansion of these structural elements, or components of the mechanism. It is for example possible to make the silicon board, then to oxidize it, in order to work coherently.
