Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne un palier amortisseur de chocs pour une pièce d'horlogerie, et plus particulièrement le palier de l'axe de balancier d'une montre mécanique, permettant d'éviter la rupture du pivot de faible diamètre, situé à son extrémité, désigné par « tigeron », en cas d'un choc axial ou latéral, pouvant résulter simplement d'un mouvement brusque du poignet du porteur.The present invention relates to a shock-absorbing bearing for a timepiece, and more particularly the bearing of the balance axis of a mechanical watch, making it possible to avoid the rupture of the small diameter pivot, located at its end, designated by “tigeron”, in the event of an axial or lateral impact, which may simply result from a sudden movement of the wearer's wrist.

ARRIERE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

Les constructeurs de montres mécaniques ont conçu depuis longtemps de nombreux dispositifs permettant de faire absorber l'énergie résultant d'un choc, notamment d'un choc latéral, par l'axe en venant buter contre une paroi du trou du bloc de base qu'elle traverse, tout en permettant un déplacement momentané du tigeron avant qu'il ne soit ramené à sa position de repos sous l'action d'un ressort.Mechanical watch manufacturers have long designed numerous devices making it possible to absorb the energy resulting from a shock, in particular from a side impact, by the axis by abutting against a wall of the hole of the base block that it crosses, while allowing a temporary movement of the tigeron before it is returned to its rest position under the action of a spring.

Les figures 1 à 3 illustrent un dispositif, dit « à double cône inversé » qui est actuellement utilisé dans des pièces d'horlogerie se trouvant sur le marché. Un dispositif de ce type est par exemple décrit dans le brevet FR 1 532 798 .The Figures 1 to 3 illustrate a device, called "double inverted cone" which is currently used in timepieces on the market. A device of this type is for example described in the patent FR 1,532,798 .

Un bloc support 1, dont la base comporte un trou 2 pour le passage de l'axe de balancier 3 terminé par un tigeron 3a, permet de positionner un chaton 20 dans lequel sont immobilisées une pierre percée 4 traversée par le tigeron 3a et une pierre contre-pivot 5. Le chaton 20 est maintenu dans un logement 6 du bloc support 1 par un ressort 10 qui comprend dans cet exemple des extensions radiales 9 comprimant la pierre contre-pivot 5. Le logement 6 comporte deux portées 7, 7a en forme de cônes inversés sur lesquelles prennent appui des portées complémentaires 8, 8a du chaton 20, lesdites portées devant être exécutées avec une très grande précision. En cas de choc axial, le ressort 10 agit seul pour ramener l'axe de balancier 3 dans sa position initiale. En cas de choc latéral, c'est-à-dire lorsque l'extrémité du tigeron déséquilibre le chaton 20 hors de son plan de repos, le ressort 10 coopère avec les plans inclinés complémentaires 7, 7a ; 8, 8a pour recentrer le chaton 20. Le bloc support 1 comprend un rebord périphérique 11 dans lequel sont réalisées deux ouvertures 11a diamétralement opposées.A support block 1, the base of which has a hole 2 for the passage of the pendulum axis 3 terminated by a tigeron 3a, makes it possible to position a kitten 20 in which are immobilized a pierced stone 4 crossed by the tigeron 3a and a stone counter-pivot 5. The kitten 20 is held in a housing 6 of the support block 1 by a spring 10 which in this example comprises radial extensions 9 compressing the stone against-pivot 5. The housing 6 has two bearing surfaces 7, 7a in the form of inverted cones on which are supported complementary bearing surfaces 8, 8a of the kitten 20, said bearing surfaces having to be executed with very high precision. In in the event of an axial shock, the spring 10 acts alone to bring the balance pin 3 back to its initial position. In the event of a side impact, that is to say when the end of the tiger unbalances the kitten 20 out of its rest plane, the spring 10 cooperates with the complementary inclined planes 7, 7a; 8, 8a for refocusing the kitten 20. The support block 1 comprises a peripheral rim 11 in which two diametrically opposed openings 11a are made.

Le ressort actuel est un ressort lyre sensiblement plat 10. Un tel ressort comprend une base à partir de laquelle deux bras s'étendent. Ces bras courbes sont symétriques et s'étendent pour donner une forme de lyre. Idéalement, les bras sont agencés pour former deux parties d'un même cercle dont le centre est le centre du ressort lyre. Chaque bras comprend, à son extrémité libre, un crochet permettant de prendre appui sur des portions saillantes 11b du rebord s'étendant au niveau des ouvertures.The current spring is a substantially flat lyre spring 10. Such a spring comprises a base from which two arms extend. These curved arms are symmetrical and extend to give a lyre shape. Ideally, the arms are arranged to form two parts of the same circle whose center is the center of the moving spring. Each arm comprises, at its free end, a hook making it possible to bear on projecting portions 11b of the rim extending at the level of the openings.

Les extensions radiales 9 du ressort s'étendent depuis l'intérieur des bras.The radial extensions 9 of the spring extend from the inside of the arms.

Dans une variante visible à la figure 3, chaque bras du ressort est agencé pour être recourbé afin de former une extension. L'extension à une forme d'arc de cercle dont l'interface avec l'extension se fait par la face concave de ladite tête d'appui 9'.In a variant visible to the figure 3 , each arm of the spring is arranged to be curved in order to form an extension. The extension to a shape of an arc of a circle whose interface with the extension is made by the concave face of said support head 9 '.

Cette configuration à pour inconvénient de d'avoir qu'un seule point d'appui par bras en toutes circonstances. Ce point de contact se situe dans la partie la plus rigide de l'extension. Cela provoque ainsi une réponse imparfaite du ressort. En effet, lors d'un faible choc, avoir un point d'appui dans la partie la plus rigide pourra entrainer une absorption de l'énergie par le tigeron alors qu'en cas de chocs important, aucune progressivité ne sera présente. D'autres exemples de paliers amortisseurs comportant un ressort annulaire sont présentés dans FR 927 029 A , CH 325 895 A ou CH 294 058 A .This configuration has the disadvantage of having only one support point per arm in all circumstances. This point of contact is located in the most rigid part of the extension. This thus causes an imperfect response of the spring. In fact, during a weak shock, having a fulcrum in the most rigid part could lead to an absorption of energy by the tigeron whereas in the event of significant shocks, no progressiveness will be present. Other examples of shock absorber bearings comprising an annular spring are presented in FR 927 029 A , CH 325 895 A or CH 294 058 A .

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

La présente invention vise donc à pallier les inconvénients de l'art antérieur précité en procurant un palier amortisseur de chocs comportant une pierre percée et une pierre contre-pivot assemblées dans un chaton suspendu par un ressort lyre permettant une réponse plus progressive à des chocs.The present invention therefore aims to overcome the drawbacks of the aforementioned prior art by providing a shock absorbing bearing comprising a pierced stone and a counter-pivot stone assembled in a kitten suspended by a moving spring allowing a more progressive response to shocks.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En se référant essentiellement aux figures 4 et 5, on décrit ci-après un palier amortisseur de chocs 100 destinée à éviter la rupture ou le décentrage du tigeron 202 d'un axe de balancier 200 d'une pièce d'horlogerie. Les éléments de construction identiques ou analogues à ceux de l'art antérieur illustré en préambule par les figures 1 et 2 seront désignés par les mêmes références.Referring essentially to Figures 4 and 5 describes below a shock absorbing bearing 100 intended to avoid breaking or off-center of the tigeron 202 of a balance pin 200 of a timepiece. Construction elements identical or analogous to those of the prior art illustrated in the preamble by the Figures 1 and 2 will be designated by the same references.

Le palier comporte un bloc support 1 de forme circulaire délimitant un logement 6 dont le centre est percé d'un trou 2 pour permettre le passage d'un axe de balancier 200 terminé par un tigeron 202.The bearing comprises a support block 1 of circular shape delimiting a housing 6 whose center is pierced with a hole 2 to allow the passage of a pendulum axis 200 terminated by a tigeron 202.

Le bloc support 1 peut être, soit une pièce indépendante chassée ou fixée par tout autre moyen dans le bâti du mouvement horloger, soit faire partie d'une autre pièce du mouvement, tel qu'un pont ou une platine.The support block 1 can either be an independent part driven out or fixed by any other means in the frame of the watch movement, or be part of another part of the movement, such as a bridge or a plate.

Comme on peut le voir, le chaton 20 qui supporte la pierre percée 4 traversée par le tigeron 3a et la pierre contre-pivot 5 est amorti par un ressort 12.As can be seen, the kitten 20 which supports the pierced stone 4 traversed by the tigeron 3a and the counter-pivot stone 5 is damped by a spring 12.

En effet, le bloc support 1 comprend un rebord périphérique 9 comportant deux ouvertures 10. Ces ouvertures 10 sont diamétralement opposées et permettant la mise en place du ressort 12. En effet, le rebord périphérique 9 comprend des portions saillantes 11 s'étendant au niveau des ouvertures. Plus précisément, les deux ouvertures 10 permettant d'avoir un rebord périphérique 9 en deux parties identiques. Chaque partie comprend, à chaque extrémité, une portion saillante 11 s'étendant vers le centre de l'ouverture. Ces portions saillantes 11 permettent au ressort 12 d'y prendre appui. Le ressort 12 est un ressort de forme annulaire.Indeed, the support block 1 comprises a peripheral rim 9 having two openings 10. These openings 10 are diametrically opposite and allowing the positioning of the spring 12. In fact, the peripheral rim 9 comprises projecting portions 11 extending at the level openings. More specifically, the two openings 10 making it possible to have a peripheral rim 9 in two identical parts. Each part comprises, at each end, a projecting portion 11 extending towards the center of the opening. These projecting portions 11 allow the spring 12 to bear thereon. The spring 12 is an annular spring.

Dans un premier mode de réalisation visible à la figure 6, le ressort 12 est un ressort lyre. Un tel ressort 12 est constitué de deux bras 12a en forme d'arc de cercle reliés entre eux, via une traverse 12b, au niveau d'une de leurs extrémités, le tout formant une forme d'anneau périphérique 12'. Ce ressort 12 présente ainsi deux extrémités libres comprenant chacune une zone d'appui 12c. Une telle zone d'appui 12c peut se présenter sous la forme d'une courbure de chaque bras au niveau de son extrémité libre afin d'élargir la zone.In a first embodiment visible on the figure 6 , the spring 12 is a lyre spring. Such a spring 12 consists of two arms 12a in the form of an arc of a circle linked together, via a crosspiece 12b, at one of their ends, the whole forming a form of peripheral ring 12 '. This spring 12 thus has two free ends each comprising a support zone 12c. Such a support area 12c can be in the form of a curvature of each arm at its free end in order to widen the area.

Cette configuration du ressort permet à celui-ci d'être installé dans le logement 6 du bloc support. En effet, une fois le chaton 20 mis en place, le ressort 12 est installé. Le ressort 12 est installé de sorte à plaquer le chaton dans le logement tout en ayant la traverse 12b et les zones d'appui 12c plaquées contre les portions saillantes 11 du rebord périphérique.This configuration of the spring allows it to be installed in the housing 6 of the support block. Indeed, once the kitten 20 is in place, the spring 12 is installed. The spring 12 is installed so as to press the kitten into the housing while having the cross member 12b and the bearing zones 12c pressed against the projecting portions 11 of the peripheral rim.

Pour amortir le chaton lors d'un choc, le ressort 12 comprend au moins une extension 13. Cette extension 13 s'étend depuis l'un des bras 12a du ressort vers son centre. Cette extension faite de matière avec le ressort 12 est utilisé pour exercer une précontrainte sur la pierre contre-pivot et pour ramener le chaton dans le logement lors d'un choc.To dampen the kitten during an impact, the spring 12 comprises at least one extension 13. This extension 13 extends from one of the arms 12a of the spring towards its center. This extension made of material with the spring 12 is used to exert a prestress on the counter-pivot stone and to bring the kitten back into the housing during an impact.

Le ressort 12 est dimensionné afin que seule l'extension soit au contact de la pierre contre-pivot. De même, les bras 12a en forme d'arc de cercle sont formés pour avoir le même centre et former sensiblement un cercle de centre C. Ce centre C devient également le centre du ressort.The spring 12 is dimensioned so that only the extension is in contact with the counter-pivot stone. Likewise, the arms 12a in the form of an arc of a circle are formed to have the same center and to form substantially a circle with a center C. This center C also becomes the center of the spring.

Astucieusement selon l'invention, l'extension comprend, à son extrémité libre, une tête d'appui 14 faite de matière avec l'extension. Cette tête appui 14 présente une forme d'arc de cercle dont l'interface avec l'extension 13 est faite via la face convexe dudit arc de cercle. Chaque tête d'appui à une forme d'arc de cercle ayant une courbure plus importante que celle des bras formant le ressort. Le rayon de l'arc de cercle formant la tête d'appui est donc plus important que si cet arc de cercle avait un rayon dont el centre était le centre C du ressort. On comprend donc que le centre C' de l'arc de cercle de chaque bras est décalé avec le centre C du ressort comme visible à la figure 7. L'extension avec sa tête d'appui 14 présente donc une forme similaire à un Té.Cleverly according to the invention, the extension comprises, at its free end, a support head 14 made of material with the extension. This support head 14 has the shape of an arc of a circle whose interface with the extension 13 is made via the convex face of said arc of a circle. Each support head has an arc shape having a greater curvature than that of the arms forming the spring. The radius of the circular arc forming the support head is therefore greater than if this circular arc had a radius whose center was the center C of the spring. It is therefore understood that the center C 'of the arc of a circle of each arm is offset with the center C of the spring as visible on the figure 7 . The extension with its support head 14 therefore has a shape similar to a Tee.

Cette conception permet d'obtenir une extension 13 en forme de té dont les bras ont un meilleur contact avec la pierre contre pivot. La tête d'appui 14 de l'extension 13 présente avantageusement une courbure inverse par rapport à celle de l'art antérieur décrit précédemment. Cela permet de forcer le contact avec la pierre « contre pivot » dans les extrémités puisque la tête d'appui à une forme tendant à épouser la forme de la pierre contre-pivot.This design makes it possible to obtain a tee-shaped extension 13 whose arms have better contact with the stone against the pivot. The support head 14 of the extension 13 advantageously has a reverse curvature compared to that of the prior art described above. This allows to force contact with the stone "against pivot" in the ends since the support head has a shape tending to follow the shape of the stone against pivot.

Un avantage de cette configuration est d'avoir plusieurs points de contacts. Effectivement, la forme de la tête d'appui 14 lui permet d'être, au repos, au contact de la pierre contre-pivot 5 en deux endroits E1 et E2. Cette augmentation du nombre de point de contact permet d'avoir une meilleure stabilité de l'appui sur la pierre contre-pivot 5.An advantage of this configuration is to have several contact points. Indeed, the shape of the support head 14 allows it to be, at rest, in contact with the counter-pivot stone 5 in two places E1 and E2. This increase in the number of contact points allows better stability of the support on the counter-pivot stone 5.

Lors d'un choc, le chaton 20 est déplacé par l'axe et son tigeron. Ce déplacement du chaton 20 est amorti par le ressort 12. Ce ressort 12 sous l'effet de la contrainte exercée par le chaton 20, se déforme. Dans le cas du ressort 12 selon l'invention, la déformation suite à un choc a pour effet de décaler les points de contacts E1, E2. Ces points de contacts E1, E2 ont ainsi tendance à se rapprocher du centre de la tête d'appui 14. Ce décalage des points de contacts E1, E2 est dû à la forme spécifique de la tête d'appui.During an impact, the kitten 20 is moved by the axis and its tigeron. This movement of the kitten 20 is damped by the spring 12. This spring 12 under the effect of the stress exerted by the kitten 20, is deformed. In the case of the spring 12 according to the invention, the deformation following an impact has the effect of shifting the contact points E1, E2. These contact points E1, E2 thus tend to approach the center of the support head 14. This offset of the contact points E1, E2 is due to the specific shape of the support head.

Or, la zone centrale de la tête d'appui 14 est la partie la plus rigide de sorte que la déformation de cette partie 14 est moins aisée. Par conséquent, plus le choc est important et plus le contact entre l'extension 13 du ressort 12 et la pierre contre-pivot 5 se fait sur la zone la plus rigide de ladite extension. Cela permet ainsi d'obtenir un meilleur amortissement lors de grands chocs.However, the central area of the support head 14 is the most rigid part so that the deformation of this part 14 is less easy. Consequently, the greater the impact, the more the contact between the extension 13 of the spring 12 and the counter-pivot stone 5 is made on the most rigid zone of said extension. This thus provides better damping during large shocks.

Cette configuration de ressort 12 permet également d'avoir une meilleure vue sur le lubrifiant. Dans un chaton 20 tel que décrit, le lubrifiant est agencé entre la pierre percée et la pierre contre-pivot. Avec la configuration de l'extension 13 et notamment de la tête d'appui, la vue sur le centre de la pierre contre-pivot est libérée et définie. Cela est possible de par la forme de la ou des têtes d'appui qui tendent à délimiter une zone. Avec une forme d'arc de cercle dont l'interface avec l'extension se fait par la face concave, les extensions du ressort doivent être plus longues et les têtes d'appuis offre un visuel ne délimitant pas de zone et bouchant la vue sur le lubrifiant.This configuration of spring 12 also makes it possible to have a better view of the lubricant. In a kitten 20 as described, the lubricant is arranged between the pierced stone and the counter-pivot stone. With the configuration of the extension 13 and in particular of the support head, the view on the center of the counter-pivot stone is released and defined. This is possible due to the shape of the support head or heads which tend to delimit an area. With an arc shape whose interface with the extension is through the concave face, the spring extensions must be longer and the support heads offer a visual not delimiting an area and blocking the view on the lubricant.

Dans une variante visible à la figure 7, il sera possible d'avoir un ressort 12 muni de deux extensions 13, ces extensions étant disposées idéalement de façon diamétralement opposée.In a variant visible to the figure 7 , it will be possible to have a spring 12 provided with two extensions 13, these extensions being ideally arranged diametrically opposite.

Dans une autre variante visible à la figure 8, il sera possible d'avoir un ressort 12 muni de trois extensions 13, ces extensions étant disposées de façon à être angulairement répartie. Le ressort 12 comprend ainsi 3 bras 12a. Cette répartition se fera idéalement avec un angle de 60 degré. Dans cette variante, chaque extension présente ainsi son centre C'.In another variant visible on the figure 8 , it will be possible to have a spring 12 provided with three extensions 13, these extensions being arranged so as to be angularly distributed. The spring 12 thus comprises 3 arms 12a. This distribution will ideally be done at an angle of 60 degrees. In this variant, each extension thus has its center C '.

Dans un second mode de réalisation visible à la figure 9, le ressort 12 est un anneau ressort 120. Un tel anneau ressort 301 comprend des extensions radiales internes 121 disposées entre des parties annulaires 122. Ces extensions radiales internes 121 sont constituées par la bande formant l'anneau 120 qui est recourbée vers l'intérieur de l'anneau le tout formant une forme d'anneau périphérique 12'. Ces extensions radiales internes 121 sont, de préférence, régulièrement réparties sur le tour de l'anneau plat 120 de sorte que ce dernier puisse agir de façon homogène. Ces extensions radiales internes 121 comprennent chacune la tète d'appui 14 selon l'invention. On comprend alors que l'anneau ressort 120 peut être orienté d'une manière quelconque par rapport au bloc-support 1. Ce bloc support 1 comprend également un rebord périphérique muni d'une portion saillante périphérique s'étendant vers l'intérieur du bloc support. La portion saillante périphérique pourra comprendre une encoche permettant la mise en place de l'anneau ressort 120, ladite portion saillante périphérique servant à retenir l'anneau ressort en place.In a second embodiment visible on the figure 9 , the spring 12 is a spring ring 120. Such a spring ring 301 comprises internal radial extensions 121 arranged between annular parts 122. These internal radial extensions 121 are formed by the band forming the ring 120 which is bent inwards of the ring the whole forming a form of peripheral ring 12 '. These internal radial extensions 121 are preferably regularly distributed around the turn of the flat ring 120 so that the latter can act in a homogeneous manner. These internal radial extensions 121 each comprise the support head 14 according to the invention. It is then understood that the spring ring 120 can be oriented in any way relative to the support block 1. This support block 1 also includes a peripheral rim provided with a peripheral projecting portion extending towards the interior of the block support. The peripheral projecting portion may include a notch allowing the spring ring 120 to be put in place, said peripheral projecting portion serving to retain the spring ring in place.

Préférentiellement, l'anneau ressort pourra comprendre trois extensions radiales internes. Dans ce cas-là, la portion saillante périphérique pourra comprendre trois encoches permettant la mise en place de l'anneau ressort via une insertion en baïonnette, ladite extension servant à retenir l'anneau ressort en place.Preferably, the spring ring may include three internal radial extensions. In this case, the peripheral projecting portion may include three notches allowing the positioning of the spring ring via a bayonet insertion, said extension serving to retain the spring ring in place.

On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées.It will be understood that various modifications and / or improvements and / or combinations obvious to a person skilled in the art can be made to the various embodiments of the invention described above without departing from the scope of the invention defined by the appended claims.
