Description

Domaine de l'inventionField of the invention

L'invention concerne une pièce d'horlogerie à affichage double face, comportant une structure porteuse d'au moins un mouvement, et comportant sur un premier côté de ladite structure des premiers moyens d'affichage, et sur un deuxième côté de ladite structure opposé audit premier côté des deuxièmes moyens d'affichage, et comportant au moins un premier couple solidaire d'afficheurs comportant, coaxiaux selon un premier axe commun et solidaires d'un premier arbre commun, sur ledit premier côté un premier afficheur que comportent lesdits premiers moyens d'affichage, et sur ledit deuxième côté un deuxième afficheur que comportent lesdits deuxièmes moyens d'affichage.The invention relates to a timepiece with a double-sided display, comprising a structure carrying at least one movement, and comprising on a first side of said structure first display means, and on a second side of said opposite structure said first side of the second display means, and comprising at least a first integral pair of displays comprising, coaxial along a first common axis and integral with a first common shaft, on said first side a first display that said first means comprise display, and on said second side a second display which comprises said second display means.

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

Arrière-plan de l'inventionBackground of the invention

Le marché des pièces d'horlogerie, et en particulier des montres, est demandeur de modèles événementiels, ou exclusifs, ou en séries limitées, ainsi que de complications à un prix abordable. Les animations visuelles font partie des réponses que les fabricants peuvent apporter, et elles participent souvent à la notoriété d'une montre. Si certaines fonctions horlogères sont classiquement affichées sur une première face de la pièce d'horlogerie, comme le dessus de la montre, il est souvent possible d'implanter des complications, ou d'autres fonctions, sur la face opposée, en particulier quand la montre comporte une masse oscillante de petit diamètre, ou en est dépourvue ; on sait d'ailleurs que la masse oscillante peut aussi constituer un support d'information, tout en nécessitant en général un dispositif différentiel, ce qui accroît l'épaisseur et le coût de revient de la montre.The market for timepieces, and in particular watches, is demanding event models, or exclusive ones, or in limited series, as well as complications at an affordable price. Visual animations are one of the responses that manufacturers can provide, and they often contribute to the notoriety of a watch. If certain watch functions are conventionally displayed on a first side of the timepiece, such as the top of the watch, it is often possible to install complications, or other functions, on the opposite side, in particular when the watch has a small diameter oscillating weight, or does not have one; we also know that the oscillating mass can also constitute an information support, while generally requiring a differential device, which increases the thickness and the cost price of the watch.

L'implantation de tout mobile nécessite des guidages, synonymes d'épaisseur, et l'ajout d'affichages supplémentaires se heurte souvent à cette contrainte d'encombrement. Il s'agit, encore, de ne pas perturber les performances chronométriques d'une pièce d'horlogerie lors de l'entraînement de trains de mobiles dont l'équilibrage peut ne pas être optimal, surtout s'agissant d'afficheurs.
Le document CH684769G au nom de TECHNOWATCH décrit un chronographe double-face dont les deux cadrans coopèrent respectivement avec deux organes indicateurs entraînés par un seul mouvement. Ces organes indicateurs sont respectivement calés aux deux extrémités d'un axe chronométrique qui s'étend du centre d'un cadran portant une graduation chronométrique, au centre du second cadran portant des indications concentriques permettant de mesurer au moins une grandeur physique liée au temps.The installation of any mobile requires guidance, synonymous with thickness, and the addition of additional displays often comes up against this space requirement. It is also a matter of not disturbing the chronometric performance of a timepiece when driving trains of mobiles whose balancing may not be optimal, especially in the case of displays.
The document CH684769G in the name of TECHNOWATCH describes a double-sided chronograph whose two dials cooperate respectively with two indicator organs driven by a single movement. These indicator members are respectively positioned at the two ends of a chronometric axis which extends from the center of a dial carrying a chronometric graduation, to the center of the second dial bearing concentric indications making it possible to measure at least one physical quantity linked to time.

Le document FR1 190944 au nom de WEBER & CO décrit un appareil indicateur des rythmes biologiques de l'être humain. Quatre éléments indicateurs circulaires, coaxiaux ou concentriques, disposés dans un boîtier et portant respectivement des représentations des trois périodes biologiques de l'être humain et un tour de quantièmes, ces indications apparaissant à travers une ouverture du boîtier en regard d'un index de lecture.The document FR1 190944 in the name of WEBER & CO describes a device indicating the biological rhythms of the human being. Four circular, coaxial or concentric indicator elements, arranged in a case and respectively carrying representations of the three biological periods of the human being and a circle of dates, these indications appearing through an opening in the case facing a reading index .

Résumé de l'inventionSummary of the invention

L'invention se propose d'implanter un affichage supplémentaire, du côté opposé à un affichage principal classique souvent désiré par l'utilisateur. Plus particulièrement, l'invention est conçue pour réaliser un tel affichage supplémentaire sous forme d'une animation visuelle.The invention proposes to install an additional display, on the side opposite to a conventional main display often desired by the user. More particularly, the invention is designed to produce such an additional display in the form of a visual animation.

A cet effet, l'invention concerne une pièce d'horlogerie à affichage double face, selon la revendication 1 et les revendications dépendantes annexées.To this end, the invention relates to a timepiece with a double-sided display, according to claim 1 and the appended dependent claims.

Les figures dont la description suit sont un exemple d'une pièce d'horlogerie événementielle, en l'occurrence une montre dédiée à l'anniversaire d'une mission spatiale lors de laquelle les astronautes portaient une montre de la même famille.The figures described below are an example of an event timepiece, in this case a watch dedicated to the anniversary of a space mission during which the astronauts wore a watch from the same family.

Description sommaire des dessinsSummary description of the drawings

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre, en référence aux dessins annexés, où :

  • la figure 1 représente, de façon schématisée, et de face, la partie supérieure d'une montre, combinant un affichage de l'heure et un affichage de chronographe ;
  • la figure 2 représente, de façon similaire à la figure 1, la partie inférieure de la même montre, largement ouverte et fermée par une grande glace, et où est visible une animation rappelant une mission spatiale lunaire : sous la glace figure un masque qui est une représentation du sol lunaire, au-dessus d'un fond noir étoilé représentant l'espace intersidéral, dans lequel apparaît, dans un guichet ménagé dans le fond et partiellement caché par le masque lunaire, une représentation rotative de la planète Terre ; un vaisseau spatial sous forme d'un pentagone et porteur d'un astronaute figuré par un triangle circule entre le fond et le masque lunaire, et est visible tant qu'il n'est pas caché par ce dernier ;
  • la figure 3 représente le mouvement de la montre des figures 1 et 2, de façon schématisée et partielle, et en coupe passant par l'axe principal de la montre, et par un poussoir de chronographe visible en partie droite de la figure, constituant un moyen de commande ; cette figure montre trois axes parallèles selon lesquels sont agencés différents mobiles :
  • en partie centrale, un premier axe est l'axe principal de la montre, autour duquel pivotent en partie supérieure les aiguilles d'heures et de minutes et un premier afficheur, qui est ici l'aiguille de secondes chronographe, laquelle est solidaire par un premier arbre, en partie inférieure, d'un deuxième afficheur qui est ici une aiguille dont seul est visible le canon sur cette figure, et dont le corps est transparent, notamment en verre de silice ou similaire, et dont l'extrémité distale est constituée par ce vaisseau spatial;
  • en partie gauche, un deuxième axe est un axe secondaire, autour duquel pivote un deuxième arbre qui porte, en partie inférieure, un troisième afficheur qui est ici un disque représentant la planète Terre, et, en partie supérieure de la montre, un quatrième afficheur qui est une aiguille pivotant dans le petit cadran à neuf heures ;
  • en partie droite, un troisième axe est celui d'un mobile du chronographe, visible en partie supérieure ;
  • la figure 4 représente, de façon similaire à la figure 3, en coupe partielle passant par l'axe principal et par la couronne de remontage et de mise à l'heure, la montre où le mouvement est emboîté et protégé par une glace supérieure et par une glace inférieure, sur cette dernière est représenté le masque figurant le sol lunaire ;
  • la figure 5 représente, de façon similaire à la figure 4, en coupe partielle au niveau de l'extrémité inférieure du deuxième arbre, où est visible le disque représentant la planète Terre, inséré dans son guichet ; l'espace visible entre ce disque et la glace inférieure est celui dans lequel circule le deuxième afficheur porteur du vaisseau spatial;
  • la figure 6 représente, de façon similaire à la figure 2, la partie inférieure de la même montre, dans une position où le vaisseau spatial est caché par le masque, et n'est pas visible de l'utilisateur ;
  • la figure 7 représente, de façon schématisée, les zones visible à droite, et cachée à gauche, du fond représentant l'espace intersidéral ;
  • la figure 8 représente, de façon schématisée, apposé devant le mouvement d'horlogerie, ce même fond représentant l'espace intersidéral, avec une fenêtre pour l'insertion frontale du fond sur le mouvement déjà équipé du deuxième afficheur porteur du vaisseau spatial sur le premier arbre, ce deuxième afficheur comportant un corps d'aiguille transparent et étant représenté ici déjà monté et orienté à neuf heures, et ce fond comportant son guichet pour l'insertion du disque représentant la planète Terre sur le deuxième axe, et pour sa visualisation;
  • la figure 9 représente, de façon schématisée, le masque représentant le sol lunaire, apposé sur la glace inférieure, du côté du mouvement.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows, with reference to the appended drawings, where:
  • there figure 1 represents, schematically and from the front, the upper part of a watch, combining a time display and a chronograph display;

Description détaillée des modes de réalisation préférésDetailed description of the preferred embodiments

L'invention concerne une pièce d'horlogerie 1000, notamment une montre, à affichage double face.The invention relates to a timepiece 1000, in particular a watch, with a double-sided display.

Cette pièce d'horlogerie 1000 comporte une structure 2000 porteuse d'au moins un mouvement 3000, et elle comporte sur un premier côté de la structure 2000 des premiers moyens d'affichage 100, et sur un deuxième côté de la structure 2000 opposé au premier côté des deuxièmes moyens d'affichage 200.This timepiece 1000 comprises a structure 2000 carrying at least one movement 3000, and it comprises on a first side of the structure 2000 first display means 100, and on a second side of the structure 2000 opposite the first side of the second display means 200.

La pièce d'horlogerie 1000 comporte au moins un premier couple solidaire d'afficheurs, lequel comporte, coaxiaux selon un premier axe commun D1 et solidaires d'un premier arbre commun 10, sur le premier côté un premier afficheur 1 que comportent les premiers moyens d'affichage 100, et sur le deuxième côté un deuxième afficheur 2 que comportent les deuxièmes moyens d'affichage 200.The timepiece 1000 comprises at least a first integral pair of displays, which comprises, coaxial along a first common axis D1 and integral with a first common shaft 10, on the first side a first display 1 which the first means comprise display 100, and on the second side a second display 2 which the second display means 200 comprise.

Selon l'invention, le centre de masse du premier afficheur 1 et le centre de masse du deuxième afficheur 2 sont, en projection sur un plan perpendiculaire au premier axe commun D1, alignés avec le premier axe commun D1 ou confondus avec lui.According to the invention, the center of mass of the first display 1 and the center of mass of the second display 2 are, in projection on a plane perpendicular to the first common axis D1, aligned with the first common axis D1 or coincident with it.

Plus particulièrement, le centre de masse du premier afficheur 1 et le centre de masse du deuxième afficheur 2 sont, en projection sur un plan perpendiculaire au premier axe commun D1, de part et d'autre de l'axe commun D1.More particularly, the center of mass of the first display 1 and the center of mass of the second display 2 are, in projection on a plane perpendicular to the first common axis D1, on either side of the common axis D1.

Cette configuration à 180° est avantageuse car elle permet de réduire drastiquement le balourd résultant.This 180° configuration is advantageous because it drastically reduces the resulting unbalance.

Dans une autre configuration, le centre de masse du premier afficheur 1 et le centre de masse du deuxième afficheur 2 sont, en projection sur un plan perpendiculaire au premier axe commun D1, du même côté du premier axe commun D1. De préférence, cette configuration est réservée à l'utilisation d'afficheurs de faible balourd.In another configuration, the center of mass of the first display 1 and the center of mass of the second display 2 are, in projection on a plane perpendicular to the first common axis D1, on the same side of the first common axis D1. Preferably, this configuration is reserved for the use of low-balance displays.

Plus particulièrement, le premier afficheur 1 et le deuxième afficheur 2 ont, par rapport au premier axe commun D1, respectivement un premier moment d'inertie par rapport à l'axe et un deuxième moment d'inertie. Leurs inerties respectives sont inférieures ou égales à 0.388 g.mm2. Plus particulièrement, leurs inerties respectives sont inférieures ou égales à 0.248 g.mm2.More particularly, the first display 1 and the second display 2 have, with respect to the first common axis D1, respectively a first moment of inertia relative to the axis and a second moment of inertia. Their respective inertias are less than or equal to 0.388 g.mm 2 . More particularly, their respective inertias are less than or equal to 0.248 g.mm 2 .

Plus particulièrement la première inertie est inférieure ou égale à 0.14 g.mm2.More particularly the first inertia is less than or equal to 0.14 g.mm 2 .

Plus particulièrement la deuxième inertie est inférieure ou égale à 0.14 g.mm2.More particularly the second inertia is less than or equal to 0.14 g.mm 2 .

Plus particulièrement, le premier afficheur 1 ou/et le deuxième afficheur 2 est une aiguille comportant un corps d'aiguille, s'étendant radialement par rapport au premier axe commun D1, qui est en alliage léger, notamment en alliage d'aluminium et/ou de titane, ou en verre de silice, ou en matériau au moins partiellement amorphe, ou en plexiglas, ou en résine injectée, ou autre.More particularly, the first display 1 and/or the second display 2 is a needle comprising a needle body, extending radially relative to the first common axis D1, which is made of a light alloy, in particular an aluminum alloy and/or or titanium, or silica glass, or at least partially amorphous material, or plexiglass, or injected resin, or other.

De façon préférée, l'inertie globale résultante du premier afficheur 1 et du deuxième afficheur 2 est inférieure ou égale à 0.55 g.mm2.Preferably, the resulting overall inertia of the first display 1 and the second display 2 is less than or equal to 0.55 g.mm 2 .

Il est avantageux de minimiser la valeur d'inertie ; on peut aussi l'annuler en jouant sur la géométrie et/ou les matériaux de part et d'autre de l'axe.It is advantageous to minimize the inertia value; we can also cancel it by playing with the geometry and/or the materials on either side of the axis.
