Domaine de l'inventionField of the invention

L'invention concerne un ensemble réglable d'horlogerie, comportant un pont de base et au moins un pont réglable dont la position est réglable par rapport audit pont de base, parallèlement à un plan de référence.The invention relates to an adjustable timepiece assembly, comprising a base bridge and at least one adjustable bridge whose position is adjustable relative to said base bridge, parallel to a reference plane.

L'invention concerne encore un mouvement d'horlogerie comportant au moins un tel ensemble réglable.The invention also relates to a watch movement comprising at least one such adjustable assembly.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant un tel mouvement d'horlogerie, ou/et au moins un tel ensemble réglable.The invention also relates to a timepiece, including a watch, including such a watch movement, and / or at least one such adjustable assembly.

L'invention concerne le domaine des mécanismes d'horlogerie.The invention relates to the field of watch mechanisms.

Arrière-plan de l'inventionBackground of the invention

Certains mobiles d'horlogerie demandent une grande précision de l'alignement de leurs deux points de pivotement. Lorsque ceux-ci pivotent dans deux platines ou ponts séparés par plusieurs ponts, l'addition des tolérances de fabrication peut créer un écart d'alignement important.Some watchmobiles require a high accuracy in the alignment of their two pivot points. When these rotate in two decks or decks separated by multiple bridges, the addition of manufacturing tolerances can create a large misalignment.

Le document EP3144741 au nom de Vaucher propose une solution pour régler la position d'un point de pivotement d'un pont. Ce pont réglable comporte un élément de montage solidarisé à un élément de bâti d'un mouvement. Il comporte encore un premier élément mobile lié au précédent par un premier jeu d'articulations flexibles lui permettant de se déplacer le long d'un premier axe par rapport à l'élément de montage, et un deuxième élément mobile lié au premier élément mobile par l'intermédiaire d'un deuxième jeu d'articulations flexibles permettant au deuxième élément mobile de se déplacer substantiellement le long d'un deuxième axe, perpendiculaire au premier axe, par rapport au premier élément mobile, ce deuxième élément mobile supportant un élément horloger. Le premier élément mobile comprend une première fente allongée perpendiculaire au premier axe et dans lequel prend place une tête d'un premier excentrique monté en rotation à frottement gras sur un élément de bâti du mouvement. Le deuxième élément mobile comprend une deuxième fente allongée perpendiculaire au deuxième axe et dans lequel prend place une tête d'un deuxième excentrique monté en rotation à frottement gras sur un élément de bâti du mouvement horloger. La géométrie du pont est complexe et donc difficile à réaliser.The document EP3144741 in the name of Vaucher offers a solution to adjust the position of a pivot point of a bridge. This adjustable bridge comprises a mounting member secured to a frame member of a movement. It further comprises a first mobile element linked to the preceding one by a first set of flexible hinges enabling it to move along a first axis with respect to the mounting element, and a second mobile element connected to the first movable element by via a second set of flexible hinges allowing the second movable member to move substantially along a second axis, perpendicular to the first axis, relative to the first movable member, the second movable member supporting a watch element. The first movable member comprises a first elongate slot perpendicular to the first axis and in which a head of a first eccentric mounted to rotate with a friction fit on a frame member of the movement is located. The second movable element comprises a second elongated slot perpendicular to the second axis and in which takes place a head of a second eccentric mounted in rotation with friction on a frame member of the watch movement. The geometry of the bridge is complex and therefore difficult to achieve.

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

L'invention concerne un ensemble réglable 50 d'horlogerie, comportant un pont de base 1 et au moins un pont réglable 20 dont la position est réglable par rapport à ce pont de base 1 parallèlement à un plan de référence.The invention relates to an adjustable clockwork assembly 50, comprising a base bridge 1 and at least one adjustable bridge 20 whose position is adjustable relative to this base bridge 1 parallel to a reference plane.

Plus particulièrement le pont de base 1 et le pont réglables 20 sont sensiblement plans, et sont disposés sensiblement parallèlement l'un à l'autre, et le réglage concerne leur positionnement relatif l'un par rapport à l'autre, en projection sur un tel plan de référence parallèlement auquel s'étend le pont de base 1.More particularly, the basic bridge 1 and the adjustable bridge 20 are substantially planar, and are arranged substantially parallel to each other, and the adjustment concerns their relative positioning relative to each other, in projection on a such reference plane parallel to which extends the base bridge 1.

Les figures illustrent une application particulière et non limitative où le pont réglable 20 porte une pierre 200, dont il s'agit de régler précisément la position par rapport au pont de base 1The figures illustrate a particular and nonlimiting application where the adjustable bridge 20 carries a stone 200, which is to adjust precisely the position relative to the base bridge 1

Une première pièce 10 est guidée en rotation autour d'une première goupille 11 solidaire du pont de base 1. Cette première pièce 10 comporte également un premier secteur denté 12, qui engrène avec un premier pignon de réglage 13 chassé dans le pont de base 1. Un premier ressort de rappel 14 contraint la première pièce 10 pour rattraper tous les jeux.A first piece 10 is guided in rotation around a first pin 11 secured to the base bridge 1. This first piece 10 also comprises a first toothed sector 12, which meshes with a first adjustment pinion 13 driven into the base bridge 1 A first return spring 14 constrains the first piece 10 to make up all the games.

Un pont réglable 20 est guidé en rotation autour d'une deuxième goupille 21 solidaire de la première pièce 10, et qui est distante de la première goupille 11. Un deuxième secteur denté 22 solidaire du pont réglable 20 engrène avec un deuxième pignon de réglage 23. Ce deuxième pignon de réglage 23 est distant du premier pignon de réglage 13, et avantageusement le plus éloigné possible.An adjustable bridge 20 is guided in rotation about a second pin 21 secured to the first piece 10, and which is distant from the first pin 11. A second toothed sector 22 integral with the adjustable bridge 20 meshes with a second adjusting pinion 23 This second adjustment gear 23 is remote from the first adjustment gear 13, and advantageously the furthest away possible.

Le deuxième pignon de réglage 23 est chassé dans la première pièce 10. Par « chassé » on entend ici, et dans la suite de la présente description, que ces composants sont montés l'un dans l'autre avec un léger serrage, assurant une friction suffisante pour interdire tout pivotement relatif en service sous l'action des vibrations ou d'un choc, mais suffisamment faible pour autoriser un pivotement sous l'action d'un couple imprimé par un outil manipulé par un horloger, tel que tournevis ou similaire. La fourchette de serrage au diamètre est comprise entre 1 micromètres et 20 micromètres. Plus particulièrement mais non limitativement, la fourchette de serrage au diamètre est comprise entre 4 micromètres et 18 micromètres. Plus particulièrement encore, la fourchette de serrage au diamètre est comprise entre 8 micromètres et 16 micromètres. Un deuxième ressort de rappel 24 contraint le pont réglable 20 pour rattraper tous les jeux. Le pont réglable 20 est fixé sur le pont de base 1 par au moins une vis 25, et notamment deux vis 25 dans la variante illustrée par les figures. Le pont réglable 20 est en appui sur le pont de base 1, et non sur la première pièce 10.The second adjustment pinion 23 is driven into the first piece 10. By "driven" is meant here, and in the remainder of the present description, that these components are mounted one into the other with a slight tightening, ensuring a sufficient friction to prohibit any relative pivoting in use under the action of vibration or shock, but low enough to allow pivoting under the action of a torque printed by a tool manipulated by a watchmaker, such as screwdriver or the like . The clamping fork to the diameter is between 1 micrometers and 20 microns. More particularly, but not exclusively, the clamping range to the diameter is between 4 micrometers and 18 micrometers. More particularly, the diameter clamping range is between 8 micrometers and 16 micrometers. A second return spring 24 constrains the adjustable bridge 20 to make up all the games. The adjustable bridge 20 is fixed on the base bridge 1 by at least one screw 25, and in particular two screws 25 in the variant illustrated by the figures. The adjustable bridge 20 is supported on the base bridge 1, and not on the first part 10.

Une première direction formée par la première goupille 11 et le premier pignon de réglage 13 est sécante à une deuxième direction définie par la deuxième goupille 21 et le deuxième pignon de réglage 23. Compte tenu de l'encombrement du mouvement d'horlogerie et des autres composants qu'il renferme, le positionnement de ces goupilles et de ces pignons de réglage n'est pas entièrement libre, il convient de se rapprocher le plus possible d'une configuration où cette première direction et cette deuxième direction seraient perpendiculaires, pour faciliter les réglages. De préférence ces directions forment entre elles un angle compris entre 60° et 90°. Sur l'exemple de réalisation illustré par les figures, ces directions forment un angle de 60° environ. La définition de cet angle résulte aussi d'un compromis avec une autre contrainte qui nécessite de maximiser chacune des distances entre la première goupille 11 et le premier pignon de réglage 13 d'une part, et la deuxième goupille 21 et le deuxième pignon de réglage 23 d'autre part, de façon à augmenter d'autant la sensibilité de réglage.A first direction formed by the first pin 11 and the first adjustment gear 13 is secant in a second direction defined by the second pin 21 and the second adjustment gear 23. Given the size of the watch movement and other components it contains, the positioning of these pins and of these adjustment gears is not entirely free, it is necessary to approach as close as possible to a configuration where this first direction and this second direction would be perpendicular, to facilitate the settings. Preferably these directions form between them an angle of between 60 ° and 90 °. In the exemplary embodiment illustrated by the figures, these directions form an angle of approximately 60 °. The definition of this angle also results from a compromise with another constraint which requires maximizing each of the distances between the first pin 11 and the first adjusting pinion 13 on the one hand, and the second pin 21 and the second adjusting pinion 23 on the other hand, so as to increase the adjustment sensitivity.

Lorsque la ou les vis 25 du pont réglable 20 ne sont pas vissées à fond, il est possible de déplacer le pont réglable 20 (et donc, par exemple, une pierre 200 chassée dans ce pont réglable 20) selon deux arcs de cercle se rapprochant de deux droites perpendiculaires, et donc de régler la position du pont réglable 20 selon deux axes. Il est avantageux d'équiper chaque vis 25 d'un ressort 26 de friction, de type clinquant ou similaire, disposé entre le pont réglable 20 et le pont de base 1 autour de cette vis 25, ce ressort 26 de friction est agencé de façon à immobiliser le pont réglable 20 lors du dévissage de la vis 25 en phase de réglage. Lorsque l'on dévisse les deux vis de fixation 25 pour effectuer le réglage, le pont réglable 20 ne bouge pas, ce qui permet un réglage précis.When the screw or screws 25 of the adjustable bridge 20 are not screwed down, it is possible to move the adjustable bridge 20 (and therefore, for example, a stone 200 driven in this adjustable bridge 20) according to two arcs approaching each other. two perpendicular lines, and thus adjust the position of the adjustable bridge 20 along two axes. It is advantageous to equip each screw 25 with a friction spring 26, of the foil type or the like, arranged between the adjustable bridge 20 and the base bridge 1 around this screw 25, this friction spring 26 is arranged so as to to immobilize the adjustable bridge 20 during the unscrewing of the screw 25 in the adjustment phase. When unscrewing the two fixing screws 25 to make the adjustment, the adjustable bridge 20 does not move, allowing a precise adjustment.

Avec cette solution on peut facilement, une fois le mouvement complètement assemblé, aligner les deux points de pivotement en réglant le pont réglable 20 selon deux axes.With this solution, once the movement is completely assembled, it is easy to align the two pivot points by adjusting the adjustable bridge 20 along two axes.

Ainsi, la première goupille 11 est aussi éloignée que possible du premier pignon de réglage 13, de façon à ce qu'une très faible rotation imprimée à un premier élément d'orientation 131 du premier pignon de réglage 13, constitué par une fente sur les figures, se traduise par une rotation encore plus faible de la première pièce 10 par rapport à la première goupille 11, ce qui assure un réglage véritablement micrométrique. Il en est de même en ce qui concerne la deuxième goupille 21 et le deuxième pignon de réglage 23, qui comporte un deuxième élément d'orientation 231.Thus, the first pin 11 is as far away as possible from the first adjustment pinion 13, so that a very small rotation is imparted to a first orientation element 131 of the first adjustment pinion 13, constituted by a slot on the Figures, results in an even lower rotation of the first part 10 relative to the first pin 11, which ensures a truly micrometric adjustment. It is the same with regard to the second pin 21 and the second adjusting pinion 23, which comprises a second orientation member 231.

La figure 4 illustre une section selon AA de la figure 2, et montre, de gauche à droite :

  • le premier pignon de réglage 13 chassé dans un logement 130, notamment un alésage, du pont de base 1; dans la variante illustrée ce chassage est fait avec un léger serrage, une action de l'horloger sur la fente 131 permet d'effectuer le réglage. Dans une autre variante non illustrée, l'arrêt en position angulaire du premier pignon de réglage est fait par un sautoir ou similaire. Naturellement la position angulaire du premier pignon de réglage peut être graduée pour faciliter le travail de l'horloger ;
  • la superposition du pont réglable 20, de la première pièce 10, et du pont de base 1 ;
  • une pierre 200 à régler, chassée dans le pont réglable 20 ;
  • la superposition du pont réglable 20 muni d'un râteau 220 comportant le deuxième secteur denté 22 et fixé par des éléments de fixation 221 tels que rivets ou vis, ou collage, ou similaire, de la première pièce 10, et du pont de base 1 ;
  • l'appui direct du pont réglable 20 sur le pont de base 1 ;
  • la coopération du deuxième secteur denté 22 avec le deuxième pignon de réglage 23 chassé dans un logement 230, notamment un alésage, de la première pièce 10, de façon similaire au premier pignon de réglage 13.
The figure 4 illustrates a section according to AA of the figure 2 , and shows, from left to right:
  • the first adjustment gear 13 driven into a housing 130, in particular a bore, of the base bridge 1; in the variant shown this hunting is done with a slight tightening, an action of the watchmaker on the slot 131 allows the adjustment. In another variant not shown, the stopping in the angular position of the first adjustment gear is made by a jumper or the like. Naturally the angular position of the first adjustment gear can be graduated to facilitate the work of the watchmaker;
  • the superposition of the adjustable bridge 20, the first part 10, and the base bridge 1;
  • a stone 200 to adjust, driven into the adjustable bridge 20;
  • the superposition of the adjustable bridge 20 provided with a rake 220 having the second toothed sector 22 and fixed by fixing elements 221 such as rivets or screws, or bonding, or the like, of the first part 10, and the base bridge 1 ;
  • the direct support of the adjustable bridge 20 on the base bridge 1;
  • the cooperation of the second gear sector 22 with the second adjustment gear 23 driven into a housing 230, in particular a bore, of the first workpiece 10, similarly to the first adjustment gear 13.

La figure 4 montre la première pièce 10 positionnée entre le pont de base 1 et le pont réglable 20. On comprend qu'elle peut être, ou bien en appui sur le pont de base 1, ou bien en porte-à-faux sur sa seule goupille de pivotement 11, au niveau d'un appui suffisamment dimensionné.The figure 4 shows the first piece 10 positioned between the base bridge 1 and the adjustable bridge 20. It is understood that it can be, or bears on the base bridge 1, or cantilever on its single pin of pivoting 11, at a sufficiently dimensioned support.

Dans une variante, la première pièce 10 est au-dessus du pont réglable 20 lequel est en appui sur le pont de base 1, le pignon réglable 23 étant alors sous la première pièce 10. De la même façon, la première pièce 10 peut alors, ou bien être en appui sur le pont réglable 20, ou bien être en porte-à-faux sur sa seule goupille de pivotement 11.In a variant, the first piece 10 is above the adjustable bridge 20 which bears on the base bridge 1, the adjustable pinion 23 then being under the first piece 10. In the same way, the first piece 10 can then , or else be supported on the adjustable bridge 20, or be cantilever on its single pivot pin 11.

Naturellement, si l'invention est illustrée, de façon non limitative, avec un étage de réglage unique, on comprend qu'il est possible de l'extrapoler en agençant le pont réglable 20 à la façon du pont de base 1, avec un logement de goupille et un logement de pignon de réglage, et en constituant un deuxième étage comportant une deuxième pièce similaire à la première pièce 10, et par rapport à laquelle est réglable un deuxième pont réglable. La mise en série de tels étages réglables n'est limitée que par l'épaisseur totale du mouvement.Naturally, if the invention is illustrated, without limitation, with a single adjustment stage, it is understood that it is possible to extrapolate it by arranging the adjustable bridge 20 in the manner of the basic bridge 1, with a housing pin and a setting pinion housing, and constituting a second stage having a second piece similar to the first piece 10, and with respect to which is adjustable a second adjustable bridge. The placing in series of such adjustable stages is limited only by the total thickness of the movement.

De façon similaire et avantageuse, un même pont de base 1 peut servir, sur ses deux faces, de support à deux étages de réglages indépendants, l'un comportant une première pièce supérieure et un pont réglable supérieur, et l'autre comportant une première pièce inférieure et un pont réglable inférieur.Similarly and advantageously, the same base bridge 1 can serve, on its two faces, support two stages of independent settings, one having a first upper part and an upper adjustable bridge, and the other having a first lower part and a lower adjustable bridge.

L'invention concerne encore un mouvement 100 comportant au moins un tel ensemble réglable 50.The invention also relates to a movement 100 comprising at least one such adjustable assembly 50.

L'invention concerne encore une pièce d'horlogerie 1000, notamment une montre, comportant au moins un tel mouvement 100, ou/et comportant au moins un tel ensemble réglable 50.The invention also relates to a timepiece 1000, in particular a watch, comprising at least one such movement 100, and / or comprising at least one such adjustable assembly 50.

L'invention trouve tout son intérêt pour tout mécanisme d'horlogerie demandant une grande précision entre deux points de pivotement, tel qu'une montre à rattrapante ou similaire.The invention is of interest for any watchmaking mechanism requiring a high accuracy between two pivot points, such as a split watch or the like.
