Description

L'invention concerne un dispositif antichoc pour pivot de balancier de mouvement horloger.The invention relates to a shockproof device for clockwork pendulum pivot.

L'invention concerne plus particulièrement un dispositif antichoc de mouvement horloger, notamment pour pivot de balancier, comportant un chaton empierré qui est retenu élastiquement par un ressort dans un logement complémentaire agencé sur un support fixe et qui est équipé d'une pierre formant contre-pivot, du type dans lequel le ressort est constitué par une lame métallique qui est fixée en porte-à-faux sur le support, qui s'étend dans un plan radial par rapport au pivot, et qui forme un bras comportant une extrémité de fixation, et une extrémité d'appui en appui axial contre le contre-pivot de manière à retenir axialement le chaton empierré dans son logement.The invention more particularly relates to a shockproof device for a watch movement, in particular for a rocker pin, comprising a stemballed kitten which is resiliently retained by a spring in a complementary housing arranged on a fixed support and which is equipped with a counter-forming stone. pivot, of the type in which the spring is constituted by a metal blade which is fixed cantilevered on the support, which extends in a radial plane relative to the pivot, and which forms an arm having a fixing end , and a bearing end bearing axially against the pivot against pivot so as to axially retain the stone chaton in its housing.

Un tel type de dispositif antichoc est décrit et représenté notamment dans le document CH-237.999 . Dans ce document, l'extrémité de fixation du bras ressort est éloignée du contre-pivot et un espace doit être aménagé entre la surface supérieure du pont et le tronçon intermédiaire du bras, entre l'extrémité d'appui et l'extrémité de fixation, pour permettre une flexion élastique du bras autour d'un axe sensiblement transversal.Such a type of shockproof device is described and represented in particular in the document CH-237 999 . In this document, the fastening end of the spring arm is away from the pivot and a space must be provided between the upper surface of the bridge and the intermediate portion of the arm, between the bearing end and the fixing end. to allow elastic flexion of the arm about a substantially transverse axis.

La mise au point de ce type de dispositif antichoc présente des difficultés car il est difficile de contrôler précisément l'intensité de la force de rappel exercée par le ressort sur le contre-pivot, du fait du bras de levier relativement important entre l'extrémité d'appui et l'extrémité de fixation. De plus, l'intensité de la force de rappel du ressort est limitée et, lorsque l'on souhaite modifier les caractéristiques de la force de rappel, il faut modifier le bras ressort globalement sur toute sa longueur.The development of this type of shockproof device presents difficulties because it is difficult to precisely control the intensity of the restoring force exerted by the spring on the counter-pivot, because of the relatively large lever arm between the end. of support and the fixing end. In addition, the intensity of the return force of the spring is limited and, when it is desired to modify the characteristics of the restoring force, it is necessary to modify the spring arm globally over its entire length.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these disadvantages.

Dans ce but, l'invention propose un dispositif antichoc du type décrit précédemment, caractérisé en ce que le bras comporte, depuis l'extrémité de fixation, un tronçon globalement rectiligne et parallèle à une direction radiale, relativement à l'axe du pivot, un tronçon élastique en forme de secteur annulaire, et un tronçon d'appui qui s'étend globalement suivant une direction diamétrale sensiblement perpendiculaire au tronçon rectiligne de manière à constituer l'extrémité d'appui.For this purpose, the invention proposes an anti-shock device of the type described above, characterized in that the arm comprises, from the fixing end, a generally rectilinear section parallel to a radial direction relative to the axis of the pivot, an elastic section shaped annular sector, and a support section which extends generally in a diametral direction substantially perpendicular to the rectilinear section so as to constitute the bearing end.

L'invention propose aussi un mouvement horloger équipé de ce dispositif.The invention also proposes a watch movement equipped with this device.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit, faite en référence aux dessins annexés donnés à titre d'exemple non limitatifs et dans lesquels :

  • la figure 1 est une vue en coupe axiale qui représente schématiquement une partie d'un mouvement horloger équipée d'un dispositif antichoc conforme aux enseignements de l'invention ;
  • la figure 2 est une vue de dessus qui représente schématiquement le dispositif antichoc de la figure 1.
Other features and advantages of the present invention will appear more clearly on reading the detailed description which follows, made with reference to the accompanying drawings given by way of non-limiting example and in which:
  • Figure 1 is an axial sectional view which schematically shows a part of a watch movement equipped with an anti-shock device according to the teachings of the invention;
  • FIG. 2 is a view from above which schematically represents the shockproof device of FIG. 1.

Sur les figures 1 et 2, on a représenté partiellement un mouvement horloger 10 équipé d'un dispositif antichoc 12 pour pivot 14 de balancier 16 réalisé conformément aux enseignements de l'invention.In Figures 1 and 2, there is shown partially a watch movement 10 equipped with a shockproof device 12 for pivot 14 balance 16 made in accordance with the teachings of the invention.

Le mouvement horloger 10 comporte notamment une platine 18 sur laquelle est fixé un support 20 de balancier 16, qui sera désigné par pont 20, et qui est parfois appelé « coq ». Le balancier 16 est monté à rotation autour de son axe A1 entre le pont 20 et la platine 18 au moyen d'un pivot inférieur 15 et d'un pivot supérieur 14.The watch movement 10 comprises in particular a plate 18 on which is fixed a rocker support 16, which will be designated bridge 20, and which is sometimes called "cock". The rocker 16 is rotatably mounted about its axis A1 between the bridge 20 and the plate 18 by means of a lower pivot 15 and an upper pivot 14.

Le pont 20 comporte une plaque transversale de fixation 22 qui est vissée sur la face supérieure 24 de la platine 18 et une plaque transversale de support 26 qui s'étend en porte-à-faux depuis la plaque de fixation 22 en délimitant avec la face supérieure 24 de la platine 18 un espace axial pour le passage du balancier 16.The bridge 20 comprises a transverse fixing plate 22 which is screwed on the upper face 24 of the plate 18 and a transverse support plate 26 which extends cantilevered from the fixing plate 22 delimiting with the face upper 24 of the plate 18 an axial space for the passage of the balance 16.

La plaque de support 26 comporte un logement 28 muni d'une ouverture 30 qui reçoit un chaton 32 empierré formant palier pour le pivot supérieur 14 du balancier 16. Le logement 28 est ici aménagé dans une pièce intermédiaire 34 fixée sur la plaque de support 26.The support plate 26 comprises a housing 28 provided with an opening 30 which accommodates a ferroconcrete 32 forming a bearing for the upper pivot 14 of the rocker 16. The housing 28 is here arranged in an intermediate part 34 fixed on the support plate 26 .

Le logement 28 est étagé axialement et il comporte, par exemple, des portées tronconiques concaves qui sont complémentaires de surfaces tronconiques convexes réalisées sur les parois périphériques du chaton 32.The housing 28 is staggered axially and it comprises, for example, concave frustoconical bearing surfaces which are complementary to convex frustoconical surfaces made on the peripheral walls of the kitten 32.

Le chaton 32 est équipé d'une pierre inférieure 36 à trou qui est prévue pour recevoir le tronçon d'extrémité supérieure du pivot supérieur 14 du balancier 16, et d'une pierre supérieure formant contre-pivot 38. Le contre-pivot 38 comporte ici une surface supérieure 40 légèrement bombée.The kitten 32 is equipped with a lower hole-shaped stone 36 which is designed to receive the upper end portion of the upper pivot 14 of the rocker 16, and of an upper rock forming a counter-pivot 38. The counter-pivot 38 comprises here an upper surface 40 slightly convex.

Le chaton 32 est retenu élastiquement dans son logement 28 au moyen d'un ressort 42. Le ressort 42 est constitué par une lame métallique plate qui est fixée en porte-à-faux, ici sur la plaque de support 26 du pont 20. Le ressort 42 s'étend dans un plan radial, par rapport au pivot 14, et il forme un bras 42 comportant une extrémité de fixation 44 et une extrémité d'appui 46. L'extrémité d'appui 46 vient en appui axial contre la surface bombée 40 du contre-pivot 38 de manière à retenir axialement le chaton 32 dans son logement 28 dans une position de repos.The kitten 32 is resiliently retained in its housing 28 by means of a spring 42. The spring 42 is constituted by a flat metal blade which is fixed cantilevered, here on the support plate 26 of the bridge 20. spring 42 extends in a radial plane, relative to the pivot 14, and forms an arm 42 having an attachment end 44 and a bearing end 46. The bearing end 46 comes into axial support against the curved surface 40 of the pivot-pivot 38 so as to axially retain the kitten 32 in its housing 28 in a rest position.

Conformément aux enseignements de l'invention, le bras 42 comporte, depuis l'extrémité de fixation 44, un tronçon globalement rectiligne 48 et parallèle à une direction radiale, relativement à l'axe A1 du pivot 14, un tronçon élastique en forme de secteur annulaire 50, et un tronçon d'appui 46 qui s'étend globalement suivant une direction diamétrale sensiblement perpendiculaire au tronçon rectiligne 48 de manière à constituer l'extrémité d'appui 46.According to the teachings of the invention, the arm 42 comprises, from the fixing end 44, a generally rectilinear section 48 and parallel to a radial direction, relative to the axis A1 of the pivot 14, a sector-shaped elastic section. annular 50, and a bearing section 46 which extends generally in a diametral direction substantially perpendicular to the straight section 48 so as to constitute the bearing end 46.

Le secteur annulaire 50 travaille en torsion, globalement autour d'un axe parallèle au tronçon rectiligne 48, ce qui assure un contrôle optimal de la force de rappel qui est appliquée sur le chaton 32. L'optimisation de cette force de rappel peut être réalisée, par exemple, en choisissant une épaisseur radiale appropriée du secteur annulaire 50, sans modifier l'épaisseur axiale.The annular sector 50 works in torsion, generally around an axis parallel to the rectilinear section 48, which ensures optimal control of the restoring force which is applied to the kitten 32. The optimization of this restoring force can be achieved for example, by choosing a suitable radial thickness of the annular sector 50, without modifying the axial thickness.

Selon un mode de réalisation avantageux, le tronçon d'appui 46 prolonge une extrémité du secteur annulaire 50 et il comporte un trou 52 qui est coaxial à l'axe A1 du pivot 14 et qui comporte un bord périphérique curviligne 54, dans un plan radial, définissant au moins trois points d'appui 56 en contact avec la surface bombée 40 du contre-pivot 38.According to an advantageous embodiment, the support section 46 extends one end of the annular sector 50 and has a hole 52 which is coaxial with the axis A1 of the pivot 14 and which has a curvilinear peripheral edge 54, in a radial plane , defining at least three bearing points 56 in contact with the convex surface 40 of the pivoting pivot 38.

De préférence, le tronçon d'appui 46 se prolonge diamétralement, du côté opposé au secteur annulaire 50, par une languette 58.Preferably, the support section 46 extends diametrically, on the opposite side to the annular sector 50, by a tongue 58.

Le secteur annulaire 50 s'étend sur un angle sensiblement supérieur ou égal à cent quatre-vingt degrés, par exemple de l'ordre de deux cent soixante dix degrés.Annular sector 50 extends over an angle substantially greater than or equal to one hundred and eighty degrees, for example of the order of two hundred seventy degrees.

Avantageusement, le tronçon rectiligne 48 s'étend globalement suivant une direction tangente au bord périphérique externe du contre-pivot 38.Advantageously, the rectilinear section 48 extends generally in a direction tangent to the outer peripheral edge of the counter-pivot 38.

Le secteur annulaire 50 est déporté latéralement par rapport au tronçon rectiligne 48, du côté opposé au pivot 14.The annular sector 50 is offset laterally with respect to the rectilinear section 48, on the opposite side to the pivot 14.

Selon le mode de réalisation représenté, l'extrémité de fixation 44 est constituée par une plaque radiale globalement rectangulaire qui forme, avec le tronçon rectiligne 48, une équerre.According to the embodiment shown, the fixing end 44 is constituted by a generally rectangular radial plate which forms, with the rectilinear section 48, a square.

De préférence, la surface radiale inférieure 60 du tronçon rectiligne 48 est en appui axial contre la surface radiale en vis-à-vis du pont 20. Un tel agencement permet d'assurer un bon appui du bras 42 sur le pont 20 de manière que le secteur annulaire 50 travaille en torsion de manière optimale.Preferably, the lower radial surface 60 of the rectilinear section 48 bears axially against the radial surface facing the bridge 20. Such an arrangement makes it possible to ensure that the arm 42 is properly supported on the bridge 20 so that the annular sector 50 works in torsion optimally.

Selon le mode de réalisation qui vient d'être décrit, le dispositif antichoc 12 selon l'invention a été agencé du côté du pont 20. Selon une variante de réalisation (non représentée), le dispositif antichoc 12 peut être agencé du côté de la platine 18 pour être associé au pivot inférieur 15.According to the embodiment that has just been described, the shockproof device 12 according to the invention has been arranged on the side of the bridge 20. According to an alternative embodiment (not shown), the shockproof device 12 can be arranged on the side of the platinum 18 to be associated with the lower pivot 15.
