Description

Domaine techniqueTechnical area

La présente invention se rapporte aux organes de bâti pour montre. Dans la plupart des montres, le bâti est constitué d'une platine et de ponts montés sur la platine. La platine et les ponts sont en laiton usinés par des opérations mécaniques. Une telle solution permet de fabriquer un bâti de manière économique et dans une précision satisfaisante. Afin d'assurer de bonnes conditions de fonctionnement tribologiques, des pierres sont chassées dans la platine et dans les ponts.The present invention relates to watch frame members. In most watches, the frame consists of a plate and bridges mounted on the plate. The plate and the bridges are made of brass machined by mechanical operations. Such a solution makes it possible to manufacture a frame economically and in satisfactory accuracy. In order to ensure good tribological operating conditions, stones are driven into platinum and bridges.

Etat de la techniqueState of the art

Le document EP 0131267 décrit une montre dans laquelle le bâti est formé d'un empilement de plaques faites, par exemple, en corindon. Dans cette montre, les paliers sont directement réalisés dans les plaques. De telles plaques peuvent avantageusement être fabriquées par des techniques de photolithographie. Cela permet une très grande précision dans le positionnement des trous, ainsi qu'une faible épaisseur de la montre. Malheureusement, l'assemblage de plaques pose des problèmes difficilement surmontables. En effet, des plaques en matériau minéral dur tel que le corindon ou le silicium sont fragiles et le risque de rupture lors du serrage de vis ne peut être exclu. Or, cela implique des surcoûts importants. Un but de la présente invention est de pallier cet inconvénient.The document EP 0131267 describes a watch in which the frame is formed of a stack of plates made, for example, of corundum. In this watch, the bearings are directly made in the plates. Such plates can advantageously be manufactured by photolithography techniques. This allows a very high precision in the positioning of the holes, as well as a small thickness of the watch. Unfortunately, the assembly of plates poses problems that are difficult to overcome. Indeed, plates of hard mineral material such as corundum or silicon are fragile and the risk of rupture during screw tightening can not be excluded. This implies significant additional costs. An object of the present invention is to overcome this disadvantage.

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

L'ensemble représenté au dessin est une cage destinée à équiper un mouvement de montre à tourbillon. La cage comprend une platine 10 définissant un plan de référence AA, des piliers 12 et des ponts 14 et 16. Un rouage 18 et un échappement 20 sont montés pivotants entre la platine 10 et les ponts 14 et 16.The assembly shown in the drawing is a cage intended to equip a tourbillon watch movement. The cage includes a plate 10 defining a reference plane AA, pillars 12 and bridges 14 and 16. A gear train 18 and an escapement 20 are pivotally mounted between the plate 10 and the bridges 14 and 16.

Les piliers 12 sont chassés dans la platine 10. Ils comportent des surfaces d'appui au pont 14, les surfaces étant parallèles au plan AA. Comme on peut le voir plus particulièrement sur la figure 2, les piliers 12 comprennent un trou taraudé 12a et une portée 12b. Le pont 14 comporte des trous 14a engagés sur les portées 12b et en appui sur les piliers 12. Des éléments de serrage, typiquement des vis 22, sont serrés dans les trous 12a et en appui contre le pont 14.The pillars 12 are driven into the plate 10. They have bearing surfaces on the bridge 14, the surfaces being parallel to the plane AA. As can be seen more particularly on the figure 2 , the pillars 12 comprise a threaded hole 12a and a bearing 12b. The bridge 14 has holes 14a engaged on the bearing surfaces 12b and resting on the pillars 12. Clamping elements, typically screws 22, are clamped in the holes 12a and bearing against the bridge 14.

La platine 10 comprend, en outre, deux colonnes 10a comportant également des surfaces d'appui au pont 16, les surfaces étant parallèles au plan AA. Le pont 16 comporte également des trous 16a engagés sur des portées 10b dont les colonnes 10a sont munies.The plate 10 further comprises two columns 10a also having support surfaces to the bridge 16, the surfaces being parallel to the plane AA. The bridge 16 also has holes 16a engaged on spans 10b whose columns 10a are provided.

La platine 10 et les piliers 12 sont avantageusement en métal, généralement en laiton. La platine 10 est percée de trous 10b dans lesquels sont chassées des pierres 24 tenant lieu de paliers aux mobiles du rouage 18 et de l'échappement 20.The plate 10 and the pillars 12 are preferably metal, usually brass. The plate 10 is pierced with holes 10b in which are thrown stones 24 in lieu of bearings to the wheels of the wheel 18 and the exhaust 20.

Dans l'ensemble représenté sur les figures 1 et 2, les ponts 14 et 16 sont réalisés en un matériau non métallique dur, et plus particulièrement en silicium, en corindon ou en diamant. L'un comme l'autre de ces matériaux présente des coefficients de frottement avec l'acier intéressants, de telle sorte qu'il est possible d'y réaliser les paliers des mobiles du rouage 18 et de l'échappement 20. Il est ainsi possible d'éviter l'adjonction de pierres comme expliqué à propos de la platine 10. De la sorte, l'épaisseur du mouvement peut être réduite. En effet, les ponts peuvent avoir une épaisseur de l'ordre de 0.15mm. Cela n'est pas possible avec un pont en laiton.Overall represented on the Figures 1 and 2 , bridges 14 and 16 are made of a hard nonmetallic material, and more particularly of silicon, corundum or diamond. Both of these materials have coefficients of friction with steel of interest, so that it is possible to achieve the bearings of the wheels of the gear train 18 and the exhaust 20. It is thus possible to avoid the addition of stones as explained about the plate 10. In this way, the thickness of the movement can be reduced. Indeed, the bridges can have a thickness of the order of 0.15mm. This is not possible with a brass bridge.

Comme le montre la figure 5, chaque palier du pont 14 peut présenter une coupelle (30) formée en creux autour du palier. La coupelle définit un huilier formant une sorte de réservoir pour un lubrifiant, afin d'améliorer les conditions de pivotement des mobiles dans le silicium. La coupelle est typiquement de forme circulaire et est réalisée par gravage.As shown in figure 5 each bearing 14 of the bridge may have a cup (30) formed recessed around the bearing. The cup defines an oiler forming a kind of reservoir for a lubricant, in order to improve the pivoting conditions of the mobiles in the silicon. The cup is typically circular in shape and is made by etching.

Les ponts 14 et 16 sont fabriqués à partir de plaques en silicium, en corindon ou en diamant, par les techniques de photolithographie. Ces techniques permettent une très grande précision dimensionnelle. On utilisera de préférence la technique de gravure ionique réactive profonde, en anglais Deep Reactive-lon Etching (DRIE).Bridges 14 and 16 are made from silicon, corundum or diamond plates by photolithography techniques. These techniques allow a very high dimensional accuracy. The Deep Reactive-lon Etching (DRIE) deep-reactive ion etching technique is preferably used.

La fixation de plaques de matériaux tels que le silicium ou le corindon pose toutefois des problèmes, à cause de leur inaptitude à se déformer plastiquement. On a constaté que si, pour une raison ou une autre, la pression exercée sur la plaque formant l'un ou l'autre pont 14 ou 16 n'est pas régulière, par exemple à cause d'une tête de vis présentant un défaut, il y a un fort risque de rupture.Fixing plates of materials such as silicon or corundum poses problems, however, because of their inability to deform plastically. It has been found that if, for one reason or another, the pressure exerted on the plate forming one or the other bridge 14 or 16 is not regular, for example because of a screw head presenting a defect there is a high risk of rupture.

Pour éviter cet inconvénient, les ponts 14 et 16 sont revêtus, sur l'une au moins de leurs deux faces, de plages de métal identifiées par les lettres b et c, par exemple de nickel, au voisinage des trous 14a et 16a, par la technique connue sous le nom de LIGA. Cette technique permet de déposer des couches ayant une grande précision en épaisseur. De la sorte, Il est possible de réaliser un ensemble moins fragile, tout en profitant de la précision qu'offrent la photolithographie et le LIGA, en interposant des éléments métalliques aux endroits où des vis exercent une pression, de manière à éviter un contact direct entre la plaque et la base et/ou entre la plaque et les éléments de serrage.To avoid this drawback, the bridges 14 and 16 are coated, on at least one of their two faces, with metal strips identified by the letters b and c , for example nickel, in the vicinity of the holes 14a and 16a, by the technique known as LIGA. This technique makes it possible to deposit layers having a high precision in thickness. In this way, it is possible to achieve a less fragile assembly, while taking advantage of the precision offered by photolithography and LIGA, by interposing metal elements where the screws exert a pressure, so as to avoid direct contact between the plate and the base and / or between the plate and the clamping elements.

La position des ponts 14 et 16 est ainsi définie, dans un plan parallèle au plan AA, par la coopération des trous 14a et 16a pratiqués dans le silicium avec les portées 12b et 10b. La position des ponts 14 et 16 est définie, selon des axes perpendiculaires à ce plan AA, par l'appui des plages de métal 14b, 16b sur les piliers 12 ou les colonnes 10a, particulièrement sur leurs surfaces d'appui.The position of the bridges 14 and 16 is thus defined, in a plane parallel to the plane AA, by the cooperation of the holes 14a and 16a made in the silicon with the bearing surfaces 12b and 10b. The position of the bridges 14 and 16 is defined, along axes perpendicular to this plane AA, by the support of the metal surfaces 14b, 16b on the pillars 12 or the columns 10a, particularly on their bearing surfaces.

On relèvera que le pont 14, qui comprend quatre trous 14a, n'est positionné, dans un plan parallèle au plan AA, que par deux trous, les deux autres étant de plus grand diamètre. Les trous assurant le positionnement dans le plan seront avantageusement choisis de manière à ce que la distance entre eux soit la plus grande possible. Il est également possible de réaliser certains des trous de forme oblongue, de manière à éviter que de petites erreurs de position engendrent des tensions.It will be noted that the bridge 14, which comprises four holes 14a, is positioned in a plane parallel to the plane AA, only by two holes, the other two being of larger diameter. The holes ensuring positioning in the plane will advantageously be chosen so that the distance between them is as great as possible. It is also possible to realize some of holes of oblong shape, so that small position errors do not generate tensions.

Dans le mode de réalisation des figures 3 et 4, la platine 10 est également en silicium. Avec ce mode de réalisation la hauteur totale de l'ensemble peut encore être réduite.In the embodiment of Figures 3 and 4 the plate 10 is also made of silicon. With this embodiment the total height of the assembly can be further reduced.

Comme pour les ponts 14 et 16, la platine 10 comporte des trous 10c dans lesquels sont engagés les piliers 12. Elle comporte, autour de ces trous, des couches de métal formant des plages 10d déposées selon la technique connue sous le nom de LIGA.As for the bridges 14 and 16, the plate 10 has holes 10c in which the pillars 12 are engaged. It includes, around these holes, metal layers 10d forming layers deposited by the technique known as LIGA.

Ainsi qu'on peut le voir plus particulièrement sur la figure 4, l'un des piliers, portant la référence 12A, assure à la fois le positionnement dans le plan et en hauteur, alors que le deuxième pilier 12B tient lieu de cale et permet de définir l'espace entre la platine 10 et le pont 14.As can be seen more particularly on the figure 4 , one of the pillars, bearing the reference 12A, provides both positioning in the plane and height, while the second pillar 12B takes the place of wedge and defines the space between the plate 10 and the bridge 14 .

Une telle solution permet une bonne précision de la distance entre les deux plaques, celle-ci étant définie par des pièces obtenues par décolletage. De la sorte, l'ébat des mobiles peut être, pour l'essentiel, bien maîtriser. Toutefois, dans le cas où cet ébat serait trop important ou au contraire insuffisant, il est possible de l'ajuster en disposant une cale entre l'un ou l'autre des piliers 12 et la plaque.Such a solution allows good accuracy of the distance between the two plates, the latter being defined by parts obtained by bar turning. In this way, the frills of mobiles can be, for the most part, well controlled. However, in the case where this frolicking is too important or otherwise insufficient, it is possible to adjust by placing a shim between one or other of the pillars 12 and the plate.

Dans les deux modes de réalisation décrits, la couche de métal se limite au voisinage des endroits où des vis exercent une pression. Avantageusement, du métal pourrait aussi être disposé en d'autres endroits, par exemple pour rigidifier la plaque, sans pour autant augmenter l'épaisseur du mouvement.In both embodiments described, the metal layer is limited to the vicinity of the places where screws exert pressure. Advantageously, metal could also be placed in other places, for example to stiffen the plate, without increasing the thickness of the movement.

Les exemples ci-dessus n'ont été donnés qu'à titre d'illustration non limitative de l'invention et ne constituent que des modes de réalisation préférés. Ainsi, l'homme du métier peut envisager directement, pour résoudre le problème de la fragilité du silicium au serrage, de disposer des éléments d'interposition autres que les plages métalliques, au niveau des parties destinées à être en contact avec la base. Des entretoises en polymère, par exemple, peuvent être simplement interposées de manière à éviter un contact direct entre la plaque et la base ou entre la plaque et les éléments de serrage.The above examples have been given by way of non-limiting illustration of the invention and are only preferred embodiments. Thus, the skilled person can directly consider, to solve the problem of the fragility of silicon clamping, to have the interposition elements other than the metal pads, at the parts intended to be in contact with the base. Polymer spacers, for example, may simply be interposed so as to avoid direct contact between the plate and the base or between the plate and the clamping elements.
