Description

Domaine de l'inventionField of the invention

L'invention se rapporte à une pièce horlogère composite monobloc et, plus précisément, une telle pièce destinée à remplacer un ensemble petit plateau - grand plateau - cheville.The invention relates to a one-piece composite timepiece and, more specifically, to such a piece intended to replace a small tray-large plate-ankle assembly.

Arrière-plan de l'inventionBackground of the invention

Dans les systèmes d'échappement du type à ancre suisse, il est connu d'utiliser un ensemble double-plateau - cheville comme illustré à la figure 1. Cet ensemble comporte un grand plateau B qui porte une cheville A et un petit plateau C avec encoche E qui travaille avec le dard d'une ancre. La cheville A est fixée sous le grand plateau B et travaille avec la fourchette de la même ancre.In the Swiss anchor type escapement systems, it is known to use a double-tray-ankle assembly as illustrated in FIG. figure 1 . This set includes a large plate B which carries an A pin and a small plate C with notch E which works with the dart of an anchor. Ankle A is fixed under the large plate B and works with the fork of the same anchor.

Outre la hauteur importante de l'ensemble double-plateau - cheville, il est également délicat de correctement positionner la cheville A par rapport à l'encoche E du petit plateau C.In addition to the large height of the double-plate-ankle assembly, it is also difficult to correctly position the peg A with respect to the notch E of the small plate C.

Résumé de l'inventionSummary of the invention

Le but de la présente invention est de pallier tout ou partie les inconvénients cités précédemment en proposant une pièce, alternative à un ensemble double-plateau - cheville, qui est plus compacte et plus précise sans détérioration tribologique.The object of the present invention is to overcome all or part of the disadvantages mentioned above by providing a part, alternative to a double-plate-ankle assembly, which is more compact and more accurate without tribological deterioration.

A cet effet, l'invention se rapporte à une pièce horlogère de micromécanique composite monobloc comportant un premier niveau fonctionnel comportant une cheville en un premier matériau agencé pour coopérer avec un organe, le premier niveau fonctionnel comportant également une partie électroformée en un deuxième matériau métallique en recouvrement partiel avec ladite cheville et un deuxième niveau fonctionnel comportant uniquement ladite partie électroformée formant un plateau agencé pour coopérer également avec ledit organe, ledit premier matériau étant différent dudit deuxième matériau métallique.For this purpose, the invention relates to a one-piece composite micromechanical timepiece comprising a first functional level comprising a peg of a first material arranged to cooperate with a member, the first functional level also comprising an electroformed part made of a second metallic material. in partially covering with said pin and a second functional level comprising only said electroformed portion forming a plate arranged to cooperate also with said member, said first material being different from said second metal material.

Avantageusement selon l'invention, il est ainsi possible de découpler la fonction principalement tribologique de la cheville de la fonction principale de fixation de la partie électroformée par le choix d'un matériau s'adaptant parfaitement à sa fonction propre. De plus, par rapport à un ensemble double-plateau - cheville, il est immédiat que la pièce selon l'invention est beaucoup plus compacte sans perte au niveau de la qualité de fixation ou de la tribologie de la cheville tout en garantissant un meilleur positionnement entre les niveaux et les fonctions.Advantageously according to the invention, it is thus possible to decouple the mainly tribological function of the ankle from the main function of fixing the electroformed part by the choice of a material that perfectly adapts to its own function. In addition, compared to a double-plate-ankle assembly, it is immediate that the piece according to the invention is much more compact without loss in the quality of fixing or tribology of the ankle while ensuring better positioning between levels and functions.

Conformément à d'autres modes de réalisation avantageux de l'invention :

  • le premier matériau est formé en silicium monocristallin dopé ou non, en silicium polycristallin dopé ou non, en oxyde de silicium, en quartz, en silice, en corindon monocristallin, en corindon polycristallin, en alumine, en rubis, en nitrure de silicium, en carbure de silicium ;

  • said at least two blades of the ankle each extend in a circular arc;
  • the first and second functional levels are traversed by a single hole;
  • the single hole has a circular section;
  • the single hole section is substantially constant for each of the first and second functional levels or is different between each of the first and second functional levels to adjust the workpiece in both planes or only in the plane of one of the first and second levels functional;

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention se rapporte à une pièce horlogère de micromécanique 1 composite monobloc, c'est-à-dire comportant plusieurs matériaux distincts, c'est-à-dire de nature différente, et solidaires l'un dans l'autre. Comme illustré à la figure 2, la pièce 1 comporte préférentiellement au moins deux niveaux fonctionnels N1, N2 distincts.The invention relates to a one-piece composite micromechanical watchmaking piece 1, that is to say having several different materials, that is to say of different nature, and integral with each other. As illustrated in figure 2 the piece 1 preferably comprises at least two distinct functional levels N 1 , N 2 .

Ainsi, un premier niveau fonctionnel N1 comporte une cheville 3 en un premier matériau agencé pour coopérer avec un organe tel qu'une fourchette d'une ancre. Le premier niveau fonctionnel N1 comporte également une partie électroformée 5 en un deuxième matériau métallique. On comprend immédiatement que la partie 5 est rendue solidaire car elle est électroformée par-dessus la cheville 3 lors d'un procédé de galvanoplastie. Par conséquent, la partie électroformée 5 est en recouvrement partiel avec la cheville 3Thus, a first functional level N 1 comprises a pin 3 in a first material arranged to cooperate with a member such as a fork of an anchor. The first functional level N 1 also comprises an electroformed part 5 made of a second metallic material. It is immediately understood that the part 5 is made integral because it is electroformed over the ankle 3 during an electroplating process. Therefore, the electroformed portion 5 is partially overlapping with the ankle 3

Comme illustré à la figure 2, la pièce 1 comporte un deuxième niveau fonctionnel N2 comportant uniquement la partie électroformée 5 formant un plateau agencé pour coopérer également avec le même organe tel que le dard d'une ancre. On réalise immédiatement que la pièce ainsi formée est beaucoup plus compacte que l'ensemble double-plateau-cheville illustré à la figure 1. De plus, la partie 5 étant électroformée par-dessus la cheville 3 lors d'un procédé de galvanoplastie, le positionnement entre chaque niveau N1, N2 est intrinsèquement très précis.As illustrated in figure 2 , the part 1 comprises a second functional level N 2 comprising only the electroformed portion 5 forming a plate arranged to cooperate also with the same organ such as the stinger of an anchor. It is realized immediately that the piece thus formed is much more compact than the double-plate-peg assembly illustrated in FIG. figure 1 . In addition, the part 5 being electroformed over the peg 3 during an electroplating process, the positioning between each level N 1 , N 2 is intrinsically very accurate.

De manière préférée, la cheville 3 comporte un ergot 7 non recouvert par la partie électroformée 5. Comme illustré à la figure 2, l'extrémité libre de l'ergot 7 s'étrécie jusqu'à une base 9 à partir de laquelle s'étend sensiblement symétriquement au moins deux lames 6, 8 partiellement recouvertes par la partie électroformée 5.Preferably, the pin 3 comprises a lug 7 not covered by the electroformed portion 5. As illustrated in FIG. figure 2 , the free end of the lug 7 narrows to a base 9 from which extends substantially symmetrically at least two blades 6, 8 partially covered by the electroformed portion 5.

Bien entendu, la base 9 et/ou les lames 6, 8 pourrait alternativement être entièrement recouvertes par la partie électroformée 5. En effet, pour une meilleure visualisation à la figure 2 de la cheville 3, sa partie supérieure n'a pas été recouverte par la partie électroformée 5.Of course, the base 9 and / or the blades 6, 8 could alternatively be entirely covered by the electroformed portion 5. Indeed, for a better visualization at the figure 2 of the ankle 3, its upper part has not been covered by the electroformed part 5.

Comme visible à la figure 2, lesdites au moins deux lames 6, 8 de la cheville 3 s'étendent chacune selon un arc de cercle mais ne se rejoignent pas de sorte à laisser une certaine élasticité du premier matériau par rapport au deuxième matériau métallique.As visible at figure 2 , said at least two blades 6, 8 of the ankle 3 each extend in a circular arc but do not meet so as to leave some elasticity of the first material relative to the second metal material.

Les premier et deuxième niveaux fonctionnels N1, N2 sont, préférentiellement selon l'invention, traversés par un trou 11 unique afin de pourvoir y ajuster par exemple un axe ou une tige. Dans l'exemple illustré à la figure 2, le trou 11 unique comporte une section circulaire. On comprend toutefois qu'autres formes de section sont également envisageables telles qu'en forme de trèfle, de polygone ou d'ellipse.The first and second functional levels N 1 , N 2 are, preferably according to the invention, traversed by a single hole 11 in order to be able to adjust there for example an axis or a rod. In the example shown in figure 2 , the single hole 11 has a circular section. However, it is understood that other section shapes are also conceivable such clover-shaped, polygon or ellipse.

De plus, selon une première alternative, la section du trou unique 11 est sensiblement constante pour chacun des premier et deuxième niveaux fonctionnels N1, N2 afin d'ajuster la pièce 1 dans les deux plans des premier et deuxième niveaux fonctionnels N1, N2.In addition, according to a first alternative, the section of the single hole 11 is substantially constant for each of the first and second functional levels N 1 , N 2 in order to adjust the part 1 in the two planes of the first and second functional levels N 1 , N 2 .

Toutefois, selon une deuxième alternative, la section du trou unique 11 est différente entre chacun des premier et deuxième niveaux N1, N2 afin d'ajuster la pièce 1 préférentiellement dans le plan d'un des premier et deuxième niveaux fonctionnels N1, N2.However, according to a second alternative, the section of the single hole 11 is different between each of the first and second levels N 1 , N 2 so as to adjust the workpiece 1 preferably in the plane of one of the first and second functional levels N 1 , N 2 .

Enfin, la paroi 10 de la pièce 1 entourant le trou unique 11 est formée uniquement par la partie électroformée 5 afin de permettre la pièce 1 d'être chassée par exemple contre un axe ou une tige. On comprend alors que la partie électroformée 5 est déformée plastiquement pour rendre solidaire la pièce 1 monobloc contre par exemple un axe ou une tige. On réalise également l'intérêt que lesdites au moins deux lames 6, 8 de la cheville 3 puissent laisser une certaine élasticité afin de pouvoir suivre la déformation de la paroi 10.Finally, the wall 10 of the part 1 surrounding the single hole 11 is formed solely by the electroformed portion 5 to allow the part 1 to be driven for example against an axis or a rod. It is then understood that the electroformed part 5 is plastically deformed to make integral piece 1 against a for example an axis or a rod. It is also realized that said at least two blades 6, 8 of the ankle 3 can leave some elasticity in order to follow the deformation of the wall 10.

Avantageusement selon l'invention, il est ainsi possible de découpler la fonction principalement tribologique de la cheville 3 de la fonction principale de fixation de la partie électroformée 5. On peut voir également que la partie électroformée 5 forme au deuxième niveau N2 deux encoches 13, 15, l'encoche 13 pouvant avoir la même fonction que l'encoche E de l'ensemble double-plateau - cheville habituel, c'est-à-dire par exemple coopérer avec un dard d'une ancre.Advantageously according to the invention, it is thus possible to decouple the mainly tribological function of the ankle 3 from the main function of fixing the electroformed part 5. It can also be seen that the electroformed part 5 forms at the second level N 2 two notches 13 , 15, the notch 13 may have the same function as the notch E of the usual double-plate-ankle assembly, that is to say for example cooperate with a sting of an anchor.

Ainsi, le premier matériau de la cheville 3 peut être formé en silicium monocristallin dopé ou non, en silicium polycristallin dopé ou non, en oxyde de silicium, en quartz, en silice, en corindon monocristallin, en corindon polycristallin, en alumine, en rubis, en nitrure de silicium ou en carbure de silicium. Le premier matériau peut même être est au moins partiellement revêtu, notamment au niveau de l'ergot 7, d'oxyde de silicium, de nitrure de silicium, de carbure de silicium ou d'un allotrope du carbone afin d'améliorer sa tribologie. Enfin, à titre d'exemple, la partie électroformée 5 en matériau métallique peut comporter du nickel, un alliage nickel-cobalt ou un alliage nickel-phosphore.Thus, the first material of the peg 3 may be formed of monocrystalline doped silicon or not, polycrystalline silicon doped or not, silicon oxide, quartz, silica, monocrystalline corundum, polycrystalline corundum, alumina, ruby , made of silicon nitride or silicon carbide. The first material may even be at least partially coated, in particular at the pin 7, silicon oxide, silicon nitride, silicon carbide or a carbon allotrope to improve its tribology. Finally, by way of example, the electroformed part 5 made of metallic material may comprise nickel, a nickel-cobalt alloy or a nickel-phosphorus alloy.

Comme illustré à la figure 3, l'invention se rapporte également à un ensemble horloger 21 comportant un résonateur 23 balancier 25 - spiral 27 monté sur un axe 29. L'ensemble 21 comporte en outre une pièce de micromécanique composite monobloc 1 selon l'invention qui est montée sur l'axe 29 afin par exemple de coopérer avec un système d'échappement du type à ancre suisse.As illustrated in figure 3 the invention also relates to a watch assembly 21 comprising a resonator 23 balancing 25 - spiral 27 mounted on an axis 29. The assembly 21 further comprises a piece of micromechanical composite monoblock 1 according to the invention which is mounted on the 29 axis for example to cooperate with a Swiss anchor type exhaust system.

Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art. En particulier, la pièce 1 peut comporter plus que deux niveaux fonctionnels N1, N2.Of course, the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, the part 1 may comprise more than two functional levels N 1 , N 2 .

Il est également envisageable que le trou 11 soit ouvert, c'est-à-dire comporter une fente, par exemple, en direction de l'encoche 15 afin de pouvoir monter élastiquement la pièce 1 sur un axe ou une tige.It is also conceivable that the hole 11 is open, that is to say have a slot, for example, in the direction of the notch 15 in order to be able to elastically mount the part 1 on an axis or a rod.
