Description

La présente invention concerne un palier amortisseur de chocs pour un mobile tournant d'un mouvement d'horlogerie. De tels paliers sont conçus pour absorber partiellement l'énergie transmise au mobile lors d'un choc, en particulier d'un choc latéral subi par le mouvement d'horlogerie.The present invention relates to a shock-absorbing bearing for a rotating mobile of a clockwork movement. Such bearings are designed to partially absorb the energy transmitted to the mobile during an impact, in particular a side impact suffered by the watch movement.

Arrière-plan technologiqueTechnological background

Divers paliers amortisseurs de chocs du type horloger sont connus de l'homme du métier. Aux figures 1 et 2 est représenté un tel palier d'un type standard utilisé actuellement dans de nombreux mouvements horloger. Le palier 2, nommé « à double cônes inversés », est décrit par exemple dans le brevet FR 1 532 798 . Ce palier est prévu à l'extrémité de l'axe 6 d'un mobile tournant 4. Plus particulièrement, le pivot 8 de l'axe 6 est monté dans le trou d'une pierre percée 10 formant le palier 2. Ce dernier est formé d'un support 12 présentant une ouverture centrale dans son fond pour le passage de l'axe 6 du mobile tournant. Le support 12 présente un évidement à l'intérieur duquel est agencé un chaton 14. Ce chaton supporte la pierre percée 10 et une pierre contre-pivot 16 située au-dessus de cette pierre percée. Le chaton avec les deux pierres sont maintenus à l'intérieur de l'évidement du support 12 par un dispositif ressort 18 comprenant, dans la variante représentée aux figures 1 et 2, deux languettes élastiques en appui contre la surface supérieure de la pierre contre-pivot. Un tel palier de type standard est considéré esthétique en particulier grâce à la présence d'une pierre contre-pivot supérieure de relativement grand diamètre. En effet, la pierre contre-pivot participe à l'aspect esthétique du mouvement horloger et peut être considérée comme un élément décoratif de ce mouvement horloger. L'homme du métier apprécie un palier du type classique tel que représenté aux figures 1 et 2.Various shock-absorbing bearings of the watchmaking type are known to those skilled in the art. To the Figures 1 and 2 is shown such a bearing of a standard type currently used in many watch movements. The bearing 2, named "double inverted cones", is described for example in the patent FR 1 532 798 . This bearing is provided at the end of the axis 6 of a rotating wheel 4. More particularly, the pivot 8 of the shaft 6 is mounted in the hole of a pierced stone 10 forming the bearing 2. The latter is formed of a support 12 having a central opening in its bottom for the passage of the axis 6 of the rotating wheel. The support 12 has a recess inside which a kitten 14 is arranged. This kitten supports the pierced stone 10 and a counter-pivot stone 16 situated above this pierced stone. The kitten with the two stones are held inside the recess of the support 12 by a spring device 18 comprising, in the variant shown in FIGS. Figures 1 and 2 , two elastic tongues rest against the upper surface of the counter-pivot stone. Such a standard type bearing is considered aesthetic in particular because of the presence of a relatively large counter-pivot upper stone. Indeed, the counter-pivot stone contributes to the aesthetic aspect of the watch movement and can be considered as a decorative element of this watch movement. The skilled person appreciates a bearing of the conventional type as shown in FIGS. Figures 1 and 2 .

Aux figures 3 et 4 est représenté un autre palier amortisseur de chocs décrit dans le document EP 1 696 286 . Ce palier, selon cette deuxième réalisation connue, se distingue essentiellement du type classique décrit ci-avant par le fait que la pierre percée 10 et la pierre contre-pivot 16A sont assemblées à une partie centrale rigide 28 d'un dispositif élastique plan 22, c'est-à-dire s'étendant dans un plan général. Les deux pierres sont ainsi suspendues au centre du dispositif élastique dont la structure élastique ou le ressort 26 est susceptible de subir une déformation élastique axiale et radiale, c'est-à-diredans un plan général horizontal et également selon la direction longitudinale de l'axe 6 du mobile tournant. Cette deuxième réalisation présente certains avantages par rapport au palier amortisseur classique décrit précédemment, ces avantages étant exposés dans la demande de brevet EP 1 696 286 .To the Figures 3 and 4 is shown another shock absorbing bearing described in the document EP 1 696 286 . This bearing, according to this second known embodiment, differs essentially from the conventional type described above by the fact that the pierced stone 10 and the counter-pivoting stone 16A are assembled to a rigid central portion 28 of a planar elastic device 22, that is to say, extending in a general plane. The two stones are thus suspended in the center of the elastic device whose elastic structure or the spring 26 is likely to undergo an axial and radial elastic deformation, that is to say in a horizontal general plane and also in the longitudinal direction of the axis 6 of the rotating mobile. This second embodiment has certain advantages over the conventional damping bearing described above, these advantages being explained in the patent application. EP 1 696 286 .

Le dispositif élastique 22 est formé par un anneau périphérique 28 reposant sur une saillie annulaire prévue au fond de l'évidement de la base 12A. La structure élastique 26 estformée de plusieurs bras définissant autant d'éléments ressort, lesquels s'étendent en arc de cercle entre l'anneau périphérique 24 et la partie centrale 28 du dispositif élastique 22. Cette partie centrale présente une ouverture centrale dans laquelle est agencée la pierre percée 10. La pierre contre-pivot 16A posée sur la surface supérieure de cette partie centrale est maintenue en place par un capot 30 ayant des pattes de fixation 32 qui s'étendent le long de la surface latérale de la partie centrale. Le capot peut être chassé ou collé à cette partie centrale.The elastic device 22 is formed by a peripheral ring 28 resting on an annular projection provided at the bottom of the recess of the base 12A. The elastic structure 26 is formed of several arms defining as many spring elements, which extend in an arc between the peripheral ring 24 and the central portion 28 of the elastic device 22. This central portion has a central opening in which is arranged the pierced stone 10. The counter-pivoting stone 16A placed on the upper surface of this central portion is held in place by a cap 30 having attachment lugs 32 which extend along the lateral surface of the central portion. The hood can be driven out or glued to this central part.

On notera que la structure élastique 26 présente une géométrie relativement complexe avec sa pluralité de bras ressort reliant l'anneau périphérique 24 à la partie centrale rigide 28. Ainsi, le dispositif élastique 22 est réalisé de préférence par une technique LIGA connue de l'homme du métier.It will be noted that the elastic structure 26 has a relatively complex geometry with its plurality of spring arms connecting the peripheral ring 24 to the rigid central portion 28. Thus, the elastic device 22 is preferably made by a LIGA technique known to man of career.

Comme cela ressort des figures 3 et 4, le palier amortisseur de chocs 20 a un aspect visuel non classique. En effet, la vue de dessus laisse apparaître toute la structure élastique plane 26 et la pierre contre-pivot 16A est visible seulement au travers de la petite ouverture centrale du capot 30. Ainsi, la surface visible de cette pierre supérieure 16A a un diamètre sensiblement égal à celui de la pierre percée 10, lequel est petit. En comparant les dispositifs 2 et 20 respectivement représentés aux figures 1 et 3, l'observateur peut constater la différence importante dans l'aspect visuel des deux dispositifs. Comme exposé déjà précédemment, la pierre contre-pivot d'un palier amortisseur de chocs dans un mouvement d'horlogerie mécanique a un caractère ornemental et sert à donner de la valeur à ce mouvement mécanique. Le palier 20, bien que présentant plusieurs avantages techniques et une grande fonctionnalité, présente donc le problème d'une réduction importante du diamètre visible de la pierre contre-pivot 16A.As is apparent from Figures 3 and 4 the shock absorbing bearing 20 has a non-conventional visual appearance. Indeed, the top view reveals all the flat elastic structure 26 and the counter pivot stone 16A is visible only through the small central opening of the cover 30. Thus, the visible surface of this upper stone 16A has a substantially equal to that of the pierced stone 10, which is small. Comparing the devices 2 and 20 respectively represented in figures 1 and 3 , the observer can see the significant difference in the visual appearance of the two devices. As already stated above, the counter-pivoting stone of a shock-absorbing bearing in a mechanical clockwork movement has an ornamental character and serves to give value to this mechanical movement. The bearing 20, although having several technical advantages and great functionality, therefore has the problem of a significant reduction in the visible diameter of the counter-pivoting stone 16A.

A la figure 5 est représenté un palier amortisseur de chocs 42 selon un troisième mode de réalisation de l'art antérieur, tel que décrit notamment dans le brevet CH 254 854 . Le palier 42 résout le problème du diamètre réduit de la pierre contre-pivot dans le palier 20 selon le deuxième mode de réalisation de l'art antérieur décrit ci-avant. Le palier 42 comprend un dispositif élastique 22A de faible épaisseur et s'étendant dans un plan général horizontal. Bien que de forme passablement différente de la structure élastique 26 des figures 3 et 4, la structure élastique du dispositif 22A permet également une déformation élastique dans un plan horizontal et donc un déplacement horizontal de la pierre percée 10. Une telle structure élastique permettrait également une déformation axiale. Pourtant, la réalisation selon la figure 5 ne tire pas avantage de cette caractéristique du dispositif élastique 22A, contrairement au palier 20 décrit ci-avant. En effet, la pierre contre-pivot 16 n'est pas solidaire en mouvement de la pierre percée et donc de la partie centrale du dispositif élastique. Cette pierre 16, de relativement grand diamètre, est posée sur une bague ou entretoise 46 située sur la partie périphérique du dispositif 22A. Pour maintenir la pierre 16 en place et également permettre un déplacement axial de celle-ci, un deuxième dispositif élastique 48 est prévu. Ce dispositif 48 est formé de languettes élastiques 50 en appui contre la surface supérieure bombée de la pierre 16. Comme les languettes élastiques 50 sont espacées, le palier 42 laisse apparaître dans une vue de dessus la pierre 16 au travers d'une large ouverture de sorte que l'aspect visuel du palier 42 s'apparente à celui du palier classique 2 représenté aux figures 1 et 2. Par contre, pour obtenir cet effet esthétique valorisant pour le mouvement d'horlogerie, le palier 42 comprend deux dispositifs élastiques distincts 22A et 48. Le premier dispositif élastique est associé à la pierre percée 10 alors que le deuxième dispositif élastique est associé à la pierre contre-pivot supérieure 16. Le palier 42 est donc relativement complexe et onéreux. D'autres exemples de réalisations similaires sont divulgués par les documents CH 698 675 et CH 237 812 .To the figure 5 there is shown a shock absorbing bearing 42 according to a third embodiment of the prior art, as described in particular in the patent CH 254 854 . The bearing 42 solves the problem of the reduced diameter of the counter pivot stone in the bearing 20 according to the second embodiment of the prior art described above. The bearing 42 comprises an elastic device 22A of small thickness and extending in a general horizontal plane. Although of substantially different shape from the elastic structure 26 of Figures 3 and 4 the elastic structure of the device 22A also allows elastic deformation in a horizontal plane and thus a horizontal displacement of the pierced stone 10. Such elastic structure would also allow axial deformation. Yet, the realization according to the figure 5 does not take advantage of this characteristic of the elastic device 22A, unlike the bearing 20 described above. Indeed, the counter-pivot stone 16 is not integral in movement of the pierced stone and therefore of the central portion of the elastic device. This stone 16, of relatively large diameter, is placed on a ring or spacer 46 located on the peripheral portion of the device 22A. To maintain the stone 16 in place and also allow axial movement thereof, a second elastic device 48 is provided. This device 48 is formed of elastic tongues 50 bearing against the convex upper surface of the stone 16. As the elastic tabs 50 are spaced apart, the bearing 42 reveals in a top view the stone 16 through a wide opening of so that the visual appearance of the bearing 42 is similar to that of the conventional bearing 2 shown in FIGS. Figures 1 and 2 . On the other hand, in order to obtain this enhancing aesthetic effect for the watch movement, the bearing 42 comprises two separate elastic devices 22A and 48. The first elastic device is associated with the pierced stone 10 while the second elastic device is associated with the stone. 16. The bearing 42 is therefore relatively complex and expensive. Other examples of similar achievements are disclosed by the documents CH 698 675 and CH 237 812 .

Résumé de l'inventionSummary of the invention

La présente invention a pour but de pallier les inconvénients de l'art antérieur et en particulier de proposer un palier amortisseur de chocs qui soit efficace, peu onéreux et présentant un aspect classique avec une pierre contre-pivot ayant un grand diamètre relativement à celui de la pierre percée. En particulier, la présente invention se propose d'atteindre ce but en conservant les avantages fonctionnels donnés par un palier du type décrit aux figures 3 et 4.The present invention aims to overcome the disadvantages of the prior art and in particular to provide a shock absorbing bearing which is effective, inexpensive and having a conventional appearance with a counter-pivot stone having a large diameter relative to that of the pierced stone. In particular, the present invention proposes to achieve this goal while preserving the functional advantages given by a bearing of the type described in Figures 3 and 4 .

A cet effet, la présente invention a pour objet un mouvement d'horlogerie muni d'au moins un palier amortisseur de chocs pour un mobile tournant, ce palier amortisseur de chocs comprenant un dispositif élastique présentant une partie centrale rigide et une structure élastique reliée à cette partie centrale et s'étendant en périphérie de celle-ci, la partie centrale ayant une ouverture dans laquelle est agencée une pierre percée et étant reliée matériellement au mouvement d'horlogerie par l'intermédiaire de la structure élastique ; de sorte que cette pierre percée est montée suspendue par la structure élastique. Le palier amortisseur comprend également une pièce contre-pivot formant une butée supérieure pour le pivot de l'axe du mobile tournant et assemblée à la partie centrale du dispositif élastique de manière à être solidaire en mouvement de cette partie centrale, la structure élastique étant agencée pour permettre un mouvement radial / horizontal de la partie centrale supportant la pierre percée et également un mouvement axial de cette partie centrale, c'est-à-dire un mouvement selon l'axe géométrique défini par l'axe matériel du mobile tournant monté dans le palier amortisseur de chocs. Le mouvement d'horlogerie est caractérisé par le fait que la pierre contre-pivot est au moins partiellement au-dessus de la structure élastique et qu'elle est fixée à la partie centrale du dispositif élastique par un lien matériel entre cette partie centrale et la face inférieure de la pierre contre-pivot.For this purpose, the subject of the present invention is a watch movement provided with at least one shock-absorbing bearing for a rotating mobile, this shock-absorbing bearing comprising an elastic device having a rigid central part and an elastic structure connected to this central part extending at the periphery thereof, the central part having an opening in which is arranged a pierced stone and being physically connected to the clockwork movement via the elastic structure; so that this pierced stone is mounted suspended by the elastic structure. The damping bearing also comprises a counter-pivot piece forming an upper stop for the pivot of the axis of the rotating mobile and assembled to the central part of the elastic device so as to be integral in motion with this central part, the elastic structure being arranged to allow a radial / horizontal movement of the central part supporting the pierced stone and also an axial movement of this central part, that is to say a movement along the geometric axis defined by the material axis of the rotating mobile mounted in the shock absorbing bearing. The watch movement is characterized in that the counter-pivot stone is at least partially above the elastic structure and is attached to the central portion of the elastic device by a material connection between this central portion and the underside of the stone counter-pivot.

Grâce aux caractéristiques de l'invention, le palier selon l'invention comprend une pierre contre-pivot supérieure de relativement grand diamètre et résout les inconvénients du dispositif de l'art antérieur représenté à la figure 5. En effet, la fixation de la pierre contre-pivot à la partie centrale du dispositif élastique supportant la pierre percée par un lien matériel formé entre cette partie centrale et la face inférieurede la pierre contre-pivot n'engendre pas une réduction du diamètre de cette dernière. Ceci est un avantage majeur de la présente invention et permet des modes de réalisation relativement simples et peu onéreux.Thanks to the characteristics of the invention, the bearing according to the invention comprises an upper counter-pivot stone of relatively large diameter and solves the disadvantages of the device of the prior art shown in FIG. figure 5 . Indeed, the fixing of the counter-pivot stone to the central portion of the elastic device supporting the stone pierced by a material link formed between the central portion and the underside of the counter-pivot stone does not cause a reduction in the diameter of this last. This is a major advantage of the present invention and allows relatively simple and inexpensive embodiments.

Selon une caractéristique particulière de l'invention, la surface inférieure de la pierre contre-pivot et la face supérieure de la structure élastique présente entre eux une fente de manière à permettre à cette structure élastique de subir un certain déplacement axial vers le bas lors de l'amortissement d'un choc axial. Ainsi, bien que la pierre contre-pivot soit fixée à la partie centrale du dispositif élastique s'étendant dans un plan général horizontal, la pierre contre-pivot masque au moins partiellement la structure élastique tout en permettant à cette dernière de se déformer dans un plan horizontal perpendiculaire à l'axe du mobile tournant et également selon une direction axiale.According to a particular characteristic of the invention, the lower surface of the counter-pivot stone and the upper face of the elastic structure have between them a slot so as to allow this elastic structure to undergo a certain axial displacement downwards during the damping of an axial shock. Thus, although the counter-pivot stone is fixed to the central portion of the elastic device extending in a horizontal general plane, the counter-pivot stone at least partially masks the elastic structure while allowing the latter to deform in a horizontal plane perpendicular to the axis of the rotating mobile and also in an axial direction.

Selon un mode de réalisation préféré de l'invention, la face inférieure de la pierre contre-pivot comprend une première surface verticale et la partie centrale du dispositif élastique comprend une deuxième surface verticale agencée en regard de la première surface verticale. Ces caractéristiques particulières sont importantes dans le cas de chocs radiaux subis par le mouvement horloger. La surface verticale de la partie centrale forme une butée latérale pour la surface verticale de la pierre contre-pivot de sorte qu'un choc latéral ou radial n'engendre pas une rupture du lien matériel, notamment d'un soudage ou d'un collage entre la pierre contre-pivot et la partie centrale du dispositif élastique. Selon une variante préférée, les première et deuxième surfaces verticales sont cylindriques ; ce qui permet un usinage aisé en particulier pour la pierre contre-pivot. Selon une autre variante particulière, les première et deuxième surfaces verticales présentent entre elles une fente remplie d'une colle ou d'une brasure.According to a preferred embodiment of the invention, the lower face of the counter-pivot stone comprises a first vertical surface and the central portion of the elastic device comprises a second vertical surface arranged facing the first vertical surface. These particular characteristics are important in the case of radial shocks suffered by the watch movement. The vertical surface of the central portion forms a lateral abutment for the vertical surface of the counter-pivot stone so that a lateral or radial impact does not cause a break in the material connection, particularly welding or gluing. between the counter-pivot stone and the central part of the elastic device. According to a preferred variant, the first and second vertical surfaces are cylindrical; this allows easy machining especially for the counter-pivot stone. According to another particular variant, the first and second vertical surfaces have between them a slot filled with an adhesive or a solder.

Description détaillée de l'inventionDetailed description of the invention

La figure 6 représente un premier mode de réalisation d'un mouvement d'horlogerie 44 comprenant un palier amortisseur de chocs 52 pour un mobile tournant 4. Le palier 52 comprend une pierre percée 10 destinée à recevoir le pivot 8 du mobile tournant 4. Il comprend en outre un dispositif élastique 56 présentant une partie centrale rigide 58 et une structure élastique 26 reliée à la partie centrale et s'étendant en périphérie de celle-ci. La partie centrale aune ouverture dans laquelle est agencée la pierre percée 10, cette partie centrale étant reliée ainsi matériellement au mouvement d'horlogerie par l'intermédiaire de la structure élastique 26. Le palier 52 comprend également une pierre contre-pivot 16 formant une butée supérieure pour le pivot 8. Le dispositif élastique 56 et les pierres 10 et 16 sont agencées à l'intérieur d'un évidement d'une base ou d'un bloc-support 54. Le dispositif élastique 56 comprend en outre une partie périphérique annulaire 24 qui repose sur un épaulement annulaire prévu au fond de l'évidement de la base 54. Le dispositif élastique 56 peut être maintenu dans la base 54 de diverses manières connues de l'homme du métier. Ce dispositif 56 peut être chassé dans l'évidement de cette base 54 ou collé ou encore soudé. La pierre contre-pivot est assemblée à la partie centrale 58 de manière à être solidaire en mouvement de cette partie centrale. La partie centrale 58 sert donc de support à la pierre percée 10 et également à cette pierre contre-pivot, cet ensemble étant suspendu dans le palier 52 par la structure élastique 26.The figure 6 represents a first embodiment of a clockwork movement 44 comprising a shock-absorbing bearing 52 for a rotating mobile 4. The bearing 52 comprises a pierced stone 10 intended to receive the pivot 8 of the rotating mobile 4. It furthermore comprises an elastic device 56 having a rigid central portion 58 and an elastic structure 26 connected to the central portion and extending at the periphery thereof. The central part has an opening in which the pierced stone 10 is arranged, this central part being thus materially connected to the clockwork movement by means of the elastic structure 26. The bearing 52 also comprises a counter-pivoting stone 16 forming a stop The resilient device 56 and the stones 10 and 16 are arranged inside a recess of a base or a support block 54. The elastic device 56 further comprises an annular peripheral portion. 24 which rests on an annular shoulder provided at the bottom of the recess of the base 54. The elastic device 56 can be maintained in the base 54 in various ways known to those skilled in the art. This device 56 can be driven into the recess of this base 54 or glued or welded. The counter-pivot stone is assembled to the central portion 58 so as to be integral in motion of this central portion. The central part 58 thus serves as a support for the pierced stone 10 and also for this counter-pivot stone, this assembly being suspended in the bearing 52 by the elastic structure 26.

Selon l'invention, la pierre contre-pivot 16 s'étend au moins partiellement au-dessus de la structure élastique 26 et elle est fixée à la partie centrale 58 par un lien matériel entre cette partie centrale et la face inférieure 17 de cette pierre contre-pivot. Dans la variante représentée à la figure 6, le lien matériel entre la pierre 16 et la partie centrale 58 est formé par une colle 60. De préférence, la colle 60 présente une certaine épaisseur de manière à définir une fente 62 entre la face inférieure plane 17 de la pierre 16 et la surface supérieure plane de la structure élastique 26. La fente 62 a de préférence une largeur sensiblement égale ou légèrement supérieure à la fente prévue entre la structure élastique 26 et le fond de l'évidement dans la base 54. Ceci évite qu'en cas d'amortissement d'un choc axial, le bord extérieur de la pierre 16 vienne buter contre le dispositif élastique 56; ce qui pourrait entraîner un décollement de la pierre 16 et donc une rupture du lien matériel entre cette pierre et la partie centrale du dispositif élastique. La fente 62 permet donc à l'ensemble formé par la partie centrale 58, la pierre percée 10 et la pierre contre-pivot 16 de subir un certain déplacement vers le bas lors de l'amortissement d'un choc axial.According to the invention, the counter-pivoting stone 16 extends at least partially above the elastic structure 26 and is fixed to the central portion 58 by a material connection between this central portion and the lower face 17 of this stone against pivot. In the variant shown in figure 6 , the material connection between the stone 16 and the central portion 58 is formed by an adhesive 60. Preferably, the adhesive 60 has a certain thickness so as to define a slot 62 between the flat lower face 17 of the stone 16 and the surface planar top of the elastic structure 26. The slot 62 preferably has a width substantially equal to or slightly greater than the slot provided between the elastic structure 26 and the bottom of the recess in the base 54. This avoids that in case of damping an axial impact, the outer edge of the stone 16 abuts against the elastic device 56; this could lead to detachment of the stone 16 and therefore a break in the material connection between this stone and the central portion of the elastic device. The slot 62 thus allows the assembly formed by the central portion 58, the pierced stone 10 and the counter-pivot stone 16 to undergo a certain displacement downward during the damping of an axial impact.

Comme cela apparait à la figure 6, la pierre contre-pivot 16 présente un grand diamètre relativement à celui de la pierre percée 10. Grâce aux caractéristiques de l'invention, le diamètre de la pierre contre-pivot peut être seulement légèrement inférieur au diamètre de l'évidement prévu dans la base 54. Il est notamment possible de prévoir cette pierre contre-pivot avec un diamètre suffisamment grand pour que celle-ci couvre entièrement la structure élastique 26.As it appears in figure 6 , the counter-pivoting stone 16 has a large diameter relative to that of the pierced stone 10. Thanks to the features of the invention, the diameter of the counter-pivot stone may be only slightly smaller than the diameter of the recess provided in the base 54. It is in particular possible to provide the counter pivot stone with a sufficiently large diameter so that it completely covers the elastic structure 26.

A la figure 7 est représentée une variante du premier mode de réalisation décrit ci-avant. Les références décrites précédemment ne seront pas décrites ici à nouveau en détail. Le palier amortisseur de chocs 64 se distingue du palier 52 de la figure 6 par le fait que le dispositif élastique 66 comprend une partie centrale rigide 58A dont la hauteur est supérieure à celle de la structure élastique 26. La pierre contre-pivot 16 est fixée à la partie centrale 58A par une soudure / brasure 61. De manière à garantir une bonne solidité du soudage effectué, la face inférieure 17 de la pierre contre-pivot comprend une couche d'accrochage déposée au moins dans la zone prévue pour le soudage, c'est-à-dire au moins dans la zone annulaire située en facede la partie centrale 58A. Cette couche d'accrochage estformée par exemple de chrome (Cr). Sur cette couche d'accrochage est déposée de préférence une fine couche d'or (Au). Ensuite, l'apport d'une brasure est prévu, par exemple un alliage or-étain. Cette brasure peut être déposée galvaniquement soit sur la pierre 16, par-dessus la couche d'accrochage et la couche d'or, soit sur la surface supérieure de la partie centrale 58A formée par exemple de nickel (Ni) ou de nickel-phosphore (NiP). L'apport de chaleur nécessaire au soudage est effectué de diverses manières par l'homme du métier. En particulier, le soudage est effectué dans un four. On notera encore qu'une couche d'anti-diffusion, par exemple du rhodium (Rh), est de préférence déposée sur la couche d'accrochage prévue sur la pierre et/ou sur la surface supérieure de la partie centrale.To the figure 7 is shown a variant of the first embodiment described above. The references described above will not be described here again in detail. The shock absorbing bearing 64 differs from the bearing 52 of the figure 6 in that the elastic device 66 comprises a rigid central portion 58A whose height is greater than that of the elastic structure 26. The counter-pivoting stone 16 is fixed to the central portion 58A by a solder / solder 61. In order to to guarantee a good solidity of the welding carried out, the lower face 17 of the counter-pivot stone comprises a fastening layer deposited at least in the zone intended for welding, that is to say at least in the annular zone situated in facede central part 58A. This attachment layer is formed for example of chromium (Cr). On this layer of attachment is preferably deposited a thin layer of gold (Au). Then, the contribution of a solder is provided, for example an alloy gold-tin. This solder may be deposited galvanically either on the stone 16, over the bonding layer and the gold layer, or on the upper surface of the central portion 58A formed for example of nickel (Ni) or nickel-phosphorus (NiP). The heat input required for the welding is carried out in various ways by those skilled in the art. In particular, the welding is carried out in an oven. It will also be noted that an anti-diffusion layer, for example rhodium (Rh), is preferably deposited on the attachment layer provided on the stone and / or on the upper surface of the central portion.

Sur la figure 8 est représenté un deuxième mode de réalisation préféré de la présente invention. Le palier amortisseur de chocs 70 comprend un dispositif élastique 72 agencé dans la base 54. Ce dispositif élastique 72 est similaire à celui du premier mode de réalisation. Il se distingue par sa partie centrale 74 qui présente à sa face supérieure un décrochementdéfinissant une surface verticale cylindrique 76 et un épaulement annulaire 77. Cet épaulement 77 est sensiblement au niveau de la surface supérieure 80 de la structure élastique 26, de sorte que la partie centrale 74 présente une partie supérieure saillante 78 relativement à cette surface supérieure. La pierre contre-pivot 82 présente à sa face inférieure 83 également un décrochement définissant une partie inférieure saillante 84 dont la surface latérale 86 définit une surface verticale cylindrique située en regard de la surface verticale 76 de la partie centrale 74. Le bord de la partie 84 de la pierre 82 est en appui contre l'épaulement 77, un film de colle ou de brasure pouvant être prévu entre cet épaulement et la pierre contre-pivot. La surface verticale 76 forme une butée latérale pour la partie inférieure 84 de la pierre contre-pivot en cas de chocs latéraux sur le mouvement horloger dans lequel estagencé le palier 70. Les décrochements complémentaires de la partie centrale 74 et de la pierre contre-pivot permettent d'une part de centrer aisément cette pierre lors de son assemblage à la partie centrale et, d'autre part, d'éviter un effet de cisaillement entre la pierre contre-pivot et cette partie centrale lors de chocs latéraux subis par le mouvement, c'est-à-dire de chocs radiaux sur le mobile tournant 4. Ce deuxième mode de réalisation permet d'avoir une fente 62A relativement grande entre la face inférieure 83 de la pierre contre-pivot de la surface supérieure 80 de la structure élastique 26 au-dessus de laquelle s'étend cette pierre contre-pivot. La pierre contre-pivot est fixée à la partie centrale 74 au moyen d'une colle 88 ou d'une soudure. De préférence, les surfaces cylindriques 76 et 86 présentent entre elles une fente remplie d'une colle 88 ou d'une brasure.On the figure 8 there is shown a second preferred embodiment of the present invention. The shock absorbing bearing 70 comprises an elastic device 72 arranged in the base 54. This elastic device 72 is similar to that of the first embodiment. It is distinguished by its central portion 74 which has on its upper face a recess defining a cylindrical vertical surface 76 and an annular shoulder 77. This shoulder 77 is substantially at the upper surface 80 of the elastic structure 26, so that the part Central 74 has a projecting upper portion 78 relative to this upper surface. The counter-pivoting stone 82 has at its lower face 83 also a recess defining a projecting lower portion 84 whose lateral surface 86 defines a cylindrical vertical surface located facing the vertical surface 76 of the central portion 74. The edge of the part 84 of the stone 82 is in abutment against the shoulder 77, a glue or solder film that can be provided between this shoulder and the counter-pivot stone. The vertical surface 76 forms a lateral abutment for the lower part 84 of the counter-pivot stone in the event of side impacts on the watch movement in which the bearing 70 is arranged. The complementary recesses of the central part 74 and the counter-pivot stone allow on the one hand to easily center this stone during its assembly to the central part and, on the other hand, to avoid a shearing effect between the stone against pivot and this central part during lateral impacts suffered by the movement , that is to say, radial shocks on the rotating rotor 4. This second embodiment makes it possible to have a relatively large slot 62A between the lower face 83 of the counter-pivot stone of the upper surface 80 of the structure elastic 26 above which extends this stone against pivot. The counter-pivot stone is fixed to the central portion 74 by means of an adhesive 88 or a weld. Preferably, the cylindrical surfaces 76 and 86 have between them a slot filled with an adhesive 88 or a solder.

A la figure 9 est représentée une variante du deuxième de mode de réalisation de l'invention. Les références déjà décrites précédemment ne seront pas décrites ici à nouveau en détail. Le palier 90 se distingue essentiellement de celui de la figure 8 par le fait que la surface verticale 76A de la partie centrale 75 du dispositif élastique 73 est définie par la surface latérale d'un évidement 92 prévu dans la partie centrale 75. La partie inférieure 84A de la pierre contre-pivot 82A est partiellement introduite dans cet évidement 92. Dans cette variante, la surface supérieure du dispositif élastique 73 est plane et sans saillie. Dans une autre variante non représentée, il est prévu de combiner les deux variantes des figures 8 et 9. Ainsi, la partie centrale rigide du dispositif élastique présente d'une part une partie supérieure saillante et, d'autre part, un évidement à la périphérie interne de cette partie saillante. Ceci permet d'avoir une partie inférieure saillante 84A de la pierre contre-pivot avec une épaisseur supérieure et plus particulièrement d'augmenter la zone de superposition radiale des surfaces verticales 86 et 76+76A.To the figure 9 is shown a variant of the second embodiment of the invention. The references already described above will not be described here again in detail. Bearing 90 is essentially different from that of the figure 8 in that the vertical surface 76A of the central portion 75 of the elastic device 73 is defined by the lateral surface of a recess 92 provided in the central portion 75. The lower portion 84A of the counter-pivoting stone 82A is partially introduced into this recess 92. In this variant, the upper surface of the elastic device 73 is flat and without projection. In another variant not shown, it is intended to combine the two variants of the Figures 8 and 9 . Thus, the rigid central portion of the elastic device has on the one hand a projecting upper part and, on the other hand, a recess at the inner periphery of this projecting part. This allows to have a projecting lower portion 84A of the counter-pivot stone with a greater thickness and more particularly to increase the radial superposition area of the vertical surfaces 86 and 76 + 76A.

A la figure 10 est représentée une variante préférée qui se distingue des précédentes variantes par le fait que le dispositif élastique 56 a une surface supérieure 80 plane sur un seul niveau et que la pierre contre-pivot 82B a une partie inférieure saillante 84B dont le diamètre correspond sensiblement à celui de la pierre percée. Cette partie 84B est introduite dans l'ouverture traversant la partie centrale 58 et sa surface cylindrique verticale 86B est ainsi agencée en regard du haut de la paroi de cette ouverture traversante. La face inférieure 83B de la pierre contre-pivot présente un premier décrochement définissant d'une part la partie inférieure 84B et, d'autre part, une marche circulaire 134 qui est collée ou soudée à la surface supérieure 80 de la partie centrale 58. Cette face inférieure 83B présente, dans le cas du palier 130 montré à la figure 10, un deuxième décrochement 132 de manière à avoir une fente 62 suffisamment haute entre la structure élastique et la pierre contre-pivot. Dans une autre variante non représentée, il est prévu, comme dans l'exemple de la figure 6, une épaisseur de colle ou de soudure / brasure suffisante pour obtenir la fente souhaitée sans un usinage supplémentaire de la pierre contre-pivot. On a ainsi, comme dans les exemples des figures 8 et 9, une face inférieure de la pierre contre-pivot sur seulement deux niveaux horizontaux, mais avec une partie inférieure saillante qui est insérée dans l'ouverture du dispositif élastique dans laquelle est agencée la pierre percée.To the figure 10 is shown a preferred variant which differs from the previous variants in that the elastic device 56 has an upper surface 80 flat on one level and that the pivoting stone 82B has a projecting lower portion 84B whose diameter substantially corresponds to that pierced stone. This portion 84B is introduced into the opening through the central portion 58 and its vertical cylindrical surface 86B is thus arranged facing the top of the wall of this through opening. The lower face 83B of the counter-pivot stone has a first recess defining on the one hand the lower part 84B and, on the other hand, a circular step 134 which is glued or welded to the upper surface 80 of the central portion 58. This lower face 83B has, in the case of the bearing 130 shown in FIG. figure 10 a second recess 132 so as to have a sufficiently high slot 62 between the elastic structure and the counter-pivot stone. In another variant not shown, it is provided, as in the example of the figure 6 , a thickness of adhesive or solder / solder sufficient to obtain the desired slot without additional machining of the counter-pivot stone. Thus, as in the examples of Figures 8 and 9 , a lower face of the counter-pivot stone on only two horizontal levels, but with a projecting lower part which is inserted into the opening of the elastic device in which is arranged the pierced stone.

On remarquera que l'espace entre la pierre percée et la pierre contre-pivot défini une petite chambre pour l'huile de lubrification, laquelle reste au centre par un effet de capillarité. Pour permettre une introduction d'huile dans le trou de la pierre percée, il est prévu des évidements dans la paroi du trou traversant de la partie centrale du dispositif élastique. Ainsi, l'air compris dans la chambre peut être évacuée par ces évidements en périphérie de la pierre percée lors de l'introduction d'huile dans le trou de cette pierre. Ces évidements latéraux permettent également de nettoyer la chambre à huile en permettant un rinçage de celle-ci. Finalement, comme mentionné dans la demande de brevet EP 1'696'286 où ces évidements sont représentés à la figure 7, ces évidements latéraux procurent une certaine élasticité permettant de chasser la pierre percée dans la partie centrale rigide du dispositif élastique.It will be noted that the space between the pierced stone and the counter-pivot stone defines a small chamber for the lubricating oil, which remains in the center by a capillary effect. To allow an introduction of oil into the hole of the pierced stone, there are provided recesses in the wall of the through hole of the central portion of the elastic device. Thus, the air included in the chamber can be evacuated by these recesses at the periphery of the pierced stone during the introduction of oil into the hole of this stone. These lateral recesses also make it possible to clean the oil chamber by allowing it to be rinsed. Finally, as mentioned in the patent application EP 1'696'286 where these recesses are represented at the figure 7 , these lateral recesses provide a certain elasticity to drive the stone pierced in the central part rigid of the elastic device.

A la figure 11 est représenté un troisième mode de réalisation de l'invention. Le dispositif élastique 72A diffère du dispositif élastique 72 de la figure 8 en ce que la partie supérieure saillante 78A est située dans une zone interne de la partie centrale 74A. Cette partie saillante présente une surface latérale verticale 96 définissant une surface cylindrique. La pierre contre-pivot 98 présente dans sa face inférieure 100 un évidemment 102 dont la paroi latérale 104 définit une surface verticale cylindrique située en regard de la surface cylindrique 96 de la partie centrale 74A. Cette surface verticale 96 joue le rôle de butée latérale pour la pierre supérieure 98. Le palier amortisseur de chocs 94 présente les mêmes avantages que les paliers amortisseurs de chocs 70 et 90 décrits précédemment. Ce palier 94 présente un avantage supplémentaire par le fait que l'usinage effectué dans la face inférieure de 100 cette pierre contre-pivot 98 est réalisée dans une zone centrale de celle-ci. Ceci permet d'avoir pour cette pierre contre-pivot une surface supérieure bombée avec un rayon de courbure inférieur à celui des pierres 82 ou 82A du deuxième mode de réalisation décrit précédemment. Ce troisième mode de réalisation permet également de définir précisément la hauteur de la fente 62 tout en augmentant l'espace disponible pour la pierre percée 10, de sorte que la hauteur de la structure élastique 26 peut être moindre que dans le mode de réalisation précédent.To the figure 11 is shown a third embodiment of the invention. The elastic device 72A differs from the elastic device 72 of the figure 8 in that the protruding upper portion 78A is located in an inner zone of the central portion 74A. This projecting portion has a vertical side surface 96 defining a cylindrical surface. The counter-pivoting stone 98 has in its lower face 100 a recess 102 whose side wall 104 defines a cylindrical vertical surface located opposite the cylindrical surface 96 of the central portion 74A. This vertical surface 96 acts as a lateral stop for the upper stone 98. The shock-absorbing bearing 94 has the same advantages as the shock-absorbing bearings 70 and 90 described above. This bearing 94 has an additional advantage in that the machining performed in the lower face of 100 this counter-pivot stone 98 is made in a central zone thereof. This makes it possible to have for this counter-pivot stone a convex upper surface with a radius of curvature lower than that of the stones 82 or 82A of the second embodiment described above. This third embodiment also makes it possible to precisely define the height of the slot 62 while increasing the space available for the pierced stone 10, so that the height of the elastic structure 26 may be less than in the previous embodiment.

Une variante du troisième mode de réalisation est représentée à la figure 12. Le palier 110 diffère du palier 94 de la figure 11 en ce que la partie centrale 58B du dispositif élastique 66B comprend une partie annulaire supérieure 78B dont la largeur correspond sensiblement à celle de la partie centrale 58B. De plus, cette variante se distingue de la précédente par le fait que la pierre contre-pivot 112 présente une rainure 116 usinée dans sa face inférieure 114. Dans une première variante, la rainure 116 est annulaire et présente une largeur légèrement supérieure à celle de la partie supérieure 78B. Cette dernière est introduite partiellement dans la rainure 116 de la pierre 112 qui est fixée à cette partie supérieure par une colle 88 ou par une soudure / brasure. Selon une deuxième variante, les largeurs de la rainure 116 et de la partie annulaire 78B sont ajustées pour permettre à cette dernière d'être chassée dans la rainure de la pierre 112. Un avantage du palier 110 résulte du fait que la face inférieure de la pierre contre-pivot est plane à l'exception de la rainure 116 de sorte que cette face inférieure peut être aisément polie dans la région superposée au pivot du mobile tournant.A variant of the third embodiment is shown in FIG. figure 12 . The bearing 110 differs from the bearing 94 of the figure 11 in that the central portion 58B of the elastic device 66B comprises an upper annular portion 78B whose width corresponds substantially to that of the central portion 58B. In addition, this variant differs from the previous one in that the counter-pivoting stone 112 has a groove 116 machined in its lower face 114. In a first variant, the groove 116 is annular and has a width slightly greater than that of the upper part 78B. The latter is inserted partially into the groove 116 of the stone 112 which is fixed to this upper part by an adhesive 88 or by a solder / solder. In a second variant, the widths of the groove 116 and the annular portion 78B are adjusted to allow it to be driven into the groove of the stone 112. An advantage of the bearing 110 results from the fact that the underside of the counter pivot is flat except for the groove 116 so that this lower face can be easily polished in the region superimposed on the pivot of the rotating mobile.

La rainure 116 présente une surface latérale externe 117 et une surface latérale interne 118. Ces deux surfaces latérales 117 et 118 définissent des surfaces verticales cylindriques qui sont respectivement agencées en regard des deux surfaces verticales correspondantes de la partie supérieure 78B de la partie centrale du dispositif élastique.The groove 116 has an external lateral surface 117 and an internal lateral surface 118. These two lateral surfaces 117 and 118 define cylindrical vertical surfaces which are respectively arranged facing the two corresponding vertical surfaces of the upper part 78B of the central part of the device. elastic.

Finalement, un quatrième mode de réalisation de l'invention est représenté à la figure 13. Ce quatrième mode de réalisation se distingue des autres modes de réalisation principalement par la nature du lien matériel prévu entre la pierre contre- pivot 126 et la partie centrale rigide 58C du dispositif élastique 56C. Le palier 120 comprend des goupilles 124 qui sont d'une part agencées dans des trous prévus dans la partie centrale 74C et, d'autre part, dans des trous correspondant usinés dans la pierre supérieure 126. Les goupilles 124 peuvent être chassées, soudées ou collées dans la partie centrale 58C et également chassées ou collées dans les trous prévus dans la pierre contre- pivot 126. Dans le cas d'un collage, les trous usinés dans la pierre supérieure 126 présentent un diamètre légèrement supérieur à celui des goupilles 124. On remarquera que deux goupilles peuvent suffire mais on prévoira de préférence trois goupilles. Le mode de fixation de ces goupilles à la pierre supérieure 126 par collage présente un avantage industriel étant donné les tolérances d'usinage. Ainsi, si les trous présentent un diamètre légèrement supérieur à celui des goupilles, ces dernières entreront plus aisément dans les trous correspondant de la pierre contre- pivot et la colle remplira l'espace restant.Finally, a fourth embodiment of the invention is shown in FIG. figure 13 . This fourth embodiment is distinguished from the other embodiments mainly by the nature of the material connection provided between the counter pivot stone 126 and the rigid central portion 58C of the elastic device 56C. The bearing 120 comprises pins 124 which are on the one hand arranged in holes provided in the central portion 74C and, on the other hand, in corresponding holes machined in the upper stone 126. The pins 124 can be driven, welded or bonded in the central portion 58C and also driven or glued into the holes provided in the counter-pivot stone 126. In the case of gluing, the holes machined in the upper stone 126 have a diameter slightly greater than that of the pins 124. It will be noted that two pins may suffice but preferably three pins will be provided. The method of fixing these pins to the upper stone 126 by gluing has an industrial advantage given the machining tolerances. Thus, if the holes have a diameter slightly greater than that of the pins, they will more easily enter the corresponding holes of the counter-pivot stone and the glue will fill the remaining space.

D'autres variantes et en particulier d'autres moyens pour établir un lien matériel entre la pierre contre-pivot et la partie centrale du dispositif élastique peuvent être conçus par l'homme du métier sans sortir du cadre de la présente invention.Other variants and in particular other means for establishing a material connection between the counter-pivot stone and the central portion of the elastic device may be designed by those skilled in the art without departing from the scope of the present invention.
