A hand (10) for indicating hours on a first dial (1) is connected to one pivot, and a second screen (2) graduated in minutes is connected to the other pivot, around which a minute hand rotates by means of an epicyclical movement driven by linking pinions. The second dial is fixed to the hour hand.

Description

La présente invention a pour objet un dispositif de montre, ou analogue, d'un type nouveau.The present invention relates to a watch device, or analogous, of a new type.

Une montre, ou analogue, du tue à aiguilles, comporte généralement un mouvement d'horlogerie menant en rotation deux pivots coaxiaux, un pivot des heures portant une aiguille des heures, et un pivot des minutes portant une aiguille des minutes, ce dernier traversant axialement ledit pivot des heures qui est tubulaire.A watch, or the like, of the needle killer includes generally a clockwork movement leading in rotation two coaxial pivots, an hour pivot bearing a hand hours, and a minute pivot with a hand minutes, the latter axially crossing said pivot of hours which is tubular.

Le cadran de la montre ou analogue est traditionnellement divisé en douze parties égales représentant chacune une heure, et la vitesse angulaire de rotation du pivot des heures est, par un effet de démultiplication, douze fois plus petite que celle du pivot des minutes, de manière que lorsque l'aiguille des heures parcourt l'une desdites parties, soit une heure, l'aiguille des minutes parcourt tout le cadran.The watch face or the like is traditionally divided into twelve equal parts each representing one hour, and the angular speed of rotation of the hour pivot is, by a reduction effect, twelve times smaller than that of the minute pivot, so that when the hand hours runs through one of said parts, i.e. an hour, the minute hand runs across the entire dial.

La présente invention a pour but de proposer un dispositif de montre, ou analogue, du tue à aiguilles, dont le mécanisme permet d' obtenir un résultat esthétique original.The object of the present invention is to propose a device for shows, or the like, a needle killer, the mechanism of which provides an original aesthetic result.

Le dispositif de montre, ou analogue, objet de la présente invention comporte un mouvement d'horlogerie entraínant à des vitesses différentes deux pivots coaxiaux, à savoir d'une part un pivot des heures auquel est solidarisée une aiguille marquant les heures sur un cadran, et d'autre part un pivot des minutes, et il se caractérise essentiellement en ce qu'il comporte un cadran gradué en minutes qui est en orbite autour desdits pivots en étant lié à ladite aiguille des heures par l'intermédiaire d'un axe non coaxial auxdits pivots, ledit axe, qui porte une aiguille des minutes parcourant ledit cadran des minutes, étant mû en rotation dans un mouvement épicycloïdal par l'intermédiaire de pignons surmultipliés, et en ce que ledit cadran des minutes est animé en rotation, à une vitesse angulaire égale à celle de ladite aiguille des heures et dans le sens inverse de celui de ladite aiguille des minutes, par l'intermédiaire de pignons démultipliés le reliant audit pivot des minutes.The watch device, or the like, object of the present invention comprises a clockwork movement resulting in different speeds two coaxial pivots, namely on the one hand an hour pivot to which a hand is attached marking the hours on a dial, and on the other hand a pivot of the minutes, and it is essentially characterized in that it has a dial graduated in minutes which is in orbit around of said pivots by being linked to said hour hand by through an axis not coaxial with said pivots, said axis, which carries a minute hand running through said dial of minutes, being rotated in an epicyclic movement via overdrive gears, and in that said minute dial is animated in rotation, at a speed angular equal to that of said hour hand and in the opposite direction to that of the said minute hand, by via geared gears connecting it to said pivot minutes.

Conformément à l'invention une roue dentée coaxiale à l'axe qui porte l'aiguille des minutes sans être liée en rotation à celui-ci, est solidaire fixement du cadran des minutes et s'engrène sur un pignon solidaire du pivot des minutes, le rapport de transmission dudit pignon et de ladite roue dentée étant tel que ledit cadran des minutes soit animé d'un mouvement de rotation inverse de celui de ladite aiguille des minutes et de vitesse angulaire égale à celle de l'aiguille des heures, tandis qu'un second pignon est porté par ledit axe et qui, sous l'effet du pivotement de l'aiguille des heures, roule sans glisser sur une seconde roue dentée fixe et coaxiale aux pivots des heures et des minutes, le rapport de transmission entre ledit second pignon et ladite seconde roue dentée étant tel que ladite aiguille des minutes fasse un tour complet lorsque l'aiguille des heures parcourt une heure sur le cadran des heures.According to the invention a gear wheel coaxial with the axis which carries the minute hand without being linked in rotation to this one, is fixedly fixed to the minute dial and meshes with a pinion integral with the minutes pivot, the transmission ratio of said pinion and said toothed wheel being such that said minute dial is animated by a reverse rotation movement from that of said needle minutes and angular speed equal to that of the hours, while a second pinion is carried by said axis and which, under the effect of the pivoting of the hour hand, rolls without sliding on a second fixed gear coaxial with hour and minute pivots, transmission ratio between said second pinion and said second gear being such that said minute hand makes a full turn when the hour hand travels an hour on the dial hours.

Selon un mode de réalisation particulier du dispositif selon l'invention, le cadran des heures est divisé en douze heures, le pignon porté par le pivot des minutes étant d'un diamètre douze fois plus petit que le diamètre de la roue dentée solidaire du cadran des minutes, tandis que le pignon porté par l'axe portant l'aiguille des minutes est d'un diamètre douze fois plus petit que le diamètre de la roue dentée fixe.According to a particular embodiment of the device according to the invention, the hour dial is divided into twelve hours, the pinion carried by the minutes pivot being of a diameter twelve times smaller than the diameter of the gear secured to the minute dial, while the pinion carried by the axis carrying the minute hand is twelve in diameter times smaller than the diameter of the fixed gear.

D'autre part, le dispositif de montre, ou analogue, objet de la présente invention comporte un mouvement d'horlogerie entraínant à des vitesses différentes deux pivots coaxiaux, à savoir d'une part un pivot des heures auquel est solidarisée une aiguille marquant les heures sur un cadran, et d'autre part un pivot des minutes, et il se caractérise essentiellement en ce qu'il comporte un cadran gradué en minutes qui est en orbite autour desdits pivots en étant lié à ladite aiguille des heures par l'intermédiaire d'un pivot non lié en rotation audit cadran, qui porte l'aiguille des minutes, excentré par rapport auxdits pivots des heures et des minutes, et entraíné à la même vitesse angulaire par l'intermédiaire de pignons, et en ce que ledit pivot des minutes entraíne ledit cadran de minutes en sens inverse et à une vitesse angulaire égale à celle de l'aiguille des heures par l'intermédiaire de pignons démultipliés.On the other hand, the watch device, or the like, object of the present invention comprises a clockwork movement driving at different speeds two coaxial pivots, at to know on the one hand a pivot of the hours to which is united a hand marking the hours on a dial, and on the other hand a pivot of the minutes, and it is essentially characterized by what it has a dial graduated in minutes which is in orbit around said pivots by being linked to said hour hand via a pivot not linked in rotation to said audit dial, which carries the minute hand, offset from the center to the said hour and minute pivots, and driven to the same angular speed by means of pinions, and in that said pivot of the minutes drives said minute dial into opposite direction and at an angular speed equal to that of the hour hand via pinions multiplied.

Selon un mode de réalisation particulier du dispositif selon l'invention, le cadran des heures est divisé en n heures, et le cadran des minutes est solidaire d'un pignon relié à un pignon porté par le pivot des minutes par l'intermédiaire de 2p pignons doubles, les nombres de dents dudit pignon et desdits pignons doubles étant tels que la vitesse angulaire dudit cadran des minutes est (n - 1) fois plus petite que la vitesse angulaire dudit pivot des minutes.According to a particular embodiment of the device according to the invention, the hour dial is divided into n hours, and the minute dial is attached to a pinion connected to a pinion carried by the minutes pivot by through 2p double gears, the numbers of teeth said pinion and said double pinions being such that the angular speed of said minute dial is (n - 1) times smaller than the angular speed of said minutes pivot.

Le dispositif de montre, ou analogue, selon l'invention comporte ainsi une aiguille des heures sur laquelle figure un cadran des minutes excentré par rapport à l'axe de pivotement de ladite aiguille des heures, et parcouru par une aiguille des minutes, ledit cadran des minutes conservant la même orientation, c'est-à-dire celle du cadran des heures, décrivant le pourtour de ce dernier sur ladite aiguille des heures.The watch device, or the like, according to the invention thus has an hour hand with a minute dial offset from the pivot axis of said hour hand, and traversed by a hand of minutes, said minute dial retaining the same orientation, i.e. that of the hours dial, describing the periphery of the latter on said hour hand.

La présente invention sera mieux comprise à la lecture de la description qui va suivre se rapportant au dessin joint en annexe et dans lequel :

  • la figure 1 représente une vue partielle en plan d'un dispositif de montre selon l'invention.
  • la figure 2 représente une vue partielle en plan d'un premier mode de réalisation du même dispositif.
  • la figure 3 représente une vue en coupe selon l'axe XX' porté sur la figure 2.
  • la figure 4 représente une vue partielle en plan d'un second mode de réalisation du dispositif selon l'invention.
  • la figure 5 représente une vue en coupe partielle du même dispositif.
The present invention will be better understood on reading the following description relating to the attached drawing in which:
  • Figure 1 shows a partial plan view of a watch device according to the invention.
  • 2 shows a partial plan view of a first embodiment of the same device.
  • FIG. 3 represents a sectional view along the axis XX 'shown in FIG. 2.
  • FIG. 4 represents a partial plan view of a second embodiment of the device according to the invention.
  • Figure 5 shows a partial sectional view of the same device.

Si on se réfère à la figure 1, on peut voir qu'un premier mode de réalisation du dispositif de montre selon l'invention comporte un cadran des heures 1 divisé en douze parties égales, ainsi qu'une aiguille des heures 10 qui parcourt le cadran des heures 1.If we refer to Figure 1, we can see that a first mode for producing the watch device according to the invention has an hour dial 1 divided into twelve equal parts, as well as a 10 hour hand running through the dial of the hours 1.

L'aiguille des heures 1 comporte un cadran des minutes 2 divisé en soixante parties égales, et parcouru par une aiguille des minutes 20.Hour hand 1 has a divided minute dial 2 in sixty equal parts, and traversed by a needle of 20 minutes.

Si on se réfère maintenant aux figures 2 et 3, on peut voir qu'un dispositif selon l'invention comporte un mécanisme d'horlogerie 3 connu en soi, représenté uniquement sur la figure 3, animant en rotation d'une part un pivot des heures 11 et un pivot des minutes 21, ce dernier passant axialement dans le pivot des heures 11 qui est tubulaire.If we now refer to Figures 2 and 3, we can see that a device according to the invention includes a mechanism clockwork 3 known per se, shown only on the Figure 3, animating on the one hand a pivot of the hours 11 and a minute pivot 21, the latter passing axially in the 11 o'clock pivot which is tubular.

Le cadran des minutes 2 est traversé par un axe 22 qui traverse également l'aiguille des heures 10 parallèlement aux pivots 11 et 21 et à une certaine distance de ceux-ci, l'axe 22 étant en libre rotation dans le cadran des minutes 2 et l'aiguille des heures 10.The minutes dial 2 is crossed by an axis 22 which crosses also the hour hand 10 parallel to the pivots 11 and 21 and at a certain distance from them, the axis 22 being in free rotation in the minute dial 2 and the hand 10 hours.

L'aiguille des minutes 20 est solidarisée à l'une des extrémités de l'axe 22 tandis que l'autre extrémité porte un pignon 23 qui s'engrène sur une roue dentée 30, solidaire fixement du mouvement d'horlogerie, et coaxiale aux pivots 11 et 21.The minute hand 20 is secured to one of the ends of axis 22 while the other end carries a pinion 23 which meshes on a toothed wheel 30, integral fixing the clockwork movement, and coaxial with the pivots 11 and 21.

D'autre part, à la face inférieure du cadran des minutes 2, est solidarisée, coaxialement à l'axe 22, une roue dentée 24 également en libre rotation sur l'axe 22, qui s'engrène sur un pignon 25 solidaire du pivot des minutes 21 et mené en rotation par celui-ci.On the other hand, on the underside of the minute dial 2, is secured, coaxially to axis 22, a toothed wheel 24 also in free rotation on axis 22, which meshes on a pinion 25 integral with the minutes pivot 21 and driven in rotation by this one.

Dans ce mode de réalisation, où le cadran des heures est divisé en douze parties égales, sachant qu'il pourrait en être autrement, en vingt-quatre heures par exemple, le diamètre du pignon 23 est douze fois plus petit que le diamètre de la roue dentée 30, tandis que le diamètre du pignon 25 est douze fois plus petit que celui de la roue dentée 24.In this embodiment, where the hour dial is divided in twelve equal parts, knowing that it could be otherwise, in twenty-four hours for example, the diameter of the pinion 23 is twelve times smaller than the diameter of the wheel toothed 30, while the diameter of the pinion 25 is twelve times smaller than that of the gear 24.

En fonctionnement, le mouvement d'horlogerie 3 mène en rotation le pivot des heures 11 dans le sens horaire H, représenté sur les figures 1 et 2, ce qui entraíne le déplacement dans le sens H, et concentriquement au pivot des heures 11, de l'axe 22, dont le pignon 23 roule sur la roue dentée 30 ce qui provoque la rotation de l'axe 22 et donc de l'aiguille des minutes 20, le rapport d'engrenage du pignon 23 et de la roue dentée 30 faisant en sorte que l'aiguille des minutes 20 décrive un tour complet lorsque l'aiguille des heures 10 décrit un douzième du cadran des heures 1.In operation, the clockwork movement 3 rotates the hour pivot 11 clockwise H, shown on Figures 1 and 2, which causes the movement in the direction H, and concentrically with the pivot of the hours 11, of the axis 22, whose pinion 23 rolls on the toothed wheel 30 which causes the rotation of the axis 22 and therefore of the minute hand 20, the gear ratio of the pinion 23 and the toothed wheel 30 making the 20 minute hand circle complete when the 10 hour hand describes a twelfth of the hour dial 1.

Simultanément à la rotation du pivot des heures 10, le mouvement d'horlogerie mène en rotation le pivot des minutes 21 dont la vitesse angulaire est de manière classique douze fois supérieure à celle du pivot des heures 11.Simultaneously with the rotation of the 10 o'clock pivot, the clockwork movement rotates the minute pivot 21 whose angular speed is conventionally twelve times higher than that of the 11 hour pivot.

Le pignon 25 entraíne ainsi la roue dentée 24, mais dans le sens anti-horaire A, et, du fait du rapport des diamètres, à une vitesse angulaire douze fois moindre, c'est-à-dire celle du pivot des heures 11, en sorte que le cadran des minutes 2 reste toujours orienté de même façon par rapport au cadran des heures 1, bien qu'il soit déplacé par l'aiguille des heures 10.The pinion 25 thus drives the toothed wheel 24, but in the anti-clockwise A, and, due to the diameter ratio, to an angular speed twelve times lower, that is to say that of 11 o'clock pivot, so that the 2 minute dial remains always oriented in the same way with respect to the hour dial 1, although it is moved by the hour hand 10.

On notera, comme cela est visible sur la figure 3, que l'aiguille des heures 10 présente une cavité cylindrique 12, concentrique à l'axe 22, qui loge le pignon 25, la roue dentée 24 et le cadran des minutes 2, en sorte d'une part que ce dernier affleure la surface de l'aiguille des heures 1, et d'autre part que l'ensemble du mécanisme demeure invisible.It will be noted, as can be seen in FIG. 3, that the hour hand 10 has a cylindrical cavity 12, concentric with the axis 22, which houses the pinion 25, the toothed wheel 24 and the minute dial 2, so on the one hand that this last is flush with the surface of the hour hand 1, and on the other hand that the whole mechanism remains invisible.

Si on se réfère maintenant aux figures 4 et 5, on peut voir que selon un second mode de réalisation du dispositif de selon l'invention, l'aiguille des heures 10, solidaire du pivot des heures 11 lui-même traversé par le pivot des minutes 21, porte une platine 13 sur laquelle sont montés quatre pivots 4, 5, 6 et 7.If we now refer to Figures 4 and 5, we can see that according to a second embodiment of the device according to the invention, the 10 hour hand, integral with the pivot of the 11 hours itself crossed by the pivot of the minutes 21, door a plate 13 on which are mounted four pivots 4, 5, 6 and 7.

Le pivot 4 porte un pignon double 40 constitué d'une roue 41 de grand diamètre s'engrenant sur un pignon 26 solidaire du pivot des minutes 21, et d'une roue 42 de plus petit diamètre, tandis que le pivot 5 porte un pignon double 50 constitué d'une roue de grand diamètre 51 qui s'engrène sur la roue 42, et d'une roue 52 de plus petit diamètre sur laquelle s'engrène une roue 60 en libre rotation sur le pivot 6 et à laquelle est solidarisé le cadran des minutes 2.The pivot 4 carries a double pinion 40 consisting of a wheel 41 of large diameter meshing with a pinion 26 secured to the pivot minutes 21, and a wheel 42 of smaller diameter, while that the pivot 5 carries a double pinion 50 consisting of a wheel of large diameter 51 which meshes with the wheel 42, and of a wheel 52 of smaller diameter on which a wheel meshes 60 in free rotation on the pivot 6 and to which is secured the minute dial 2.

D'autre part, le pivot 7 porte un pignon 70 qui s'engrène sur le pignon 26, et sur lequel s'engrène un pignon 61 porté solidairement par le pivot 6 à l'extrémité duquel est fixée l'aiguille des minutes, non représentée, les pignons 26 et 61 étant identiques, permettant ainsi le déplacement de l'aiguille de minutes à une vitesse angulaire égale à celle du pivot des minutes 21.On the other hand, the pivot 7 carries a pinion 70 which meshes with the pinion 26, and on which meshes a pinion 61 carried integrally by pivot 6 at the end of which is fixed the minute hand, not shown, the pinions 26 and 61 being identical, thus allowing the displacement of the minute hand at an angular speed equal to that of the minute pivot 21.

Les rapports des dentures entre les différents pignons et roue sont tels que la vitesse angulaire du cadran des minutes 2 est, dans le sens anti-horaire A, (n - 1) fois inférieur à la vitesse angulaire du pivot des minutes 21, n étant le noire d'heures portées sur le cadran des heures.The ratios of the teeth between the different pinions and wheel are such that the angular speed of the dial of minutes 2 is, counterclockwise A, (n - 1) times lower than the angular speed of the minutes pivot 21, n being the black of hours worn on the hour dial.

Ainsi, à titre d'exemple pour un cadran où n est égal à douze, le pignon 26 et 61, ainsi que les roues 42 et 52 comportent chacun douze dents, tandis que les roues 41 et 51 en comportent chacune vingt-quatre, et que le pignon 60 en comporte 33, le nombre de dents du pignon 70 étant indifférent.So, as an example for a sundial where n is equal to twelve, the pinion 26 and 61, as well as the wheels 42 and 52 comprise each twelve teeth, while the wheels 41 and 51 have them each twenty-four, and that the pinion 60 has 33, the number of teeth of the pinion 70 being indifferent.

Ce second mode de réalisation présente l'avantage par rapport au premier, de permettre la mise en place d'une aiguille de réveil, en effet dans le premier mode réalisation, la présence de deux axes coaxiaux liés empêche le déplacement d'une aiguille supplémentaire.This second embodiment has the advantage over first, to allow the establishment of a needle awakening, indeed in the first embodiment, the presence of two linked coaxial axes prevents the displacement of a additional needle.

On notera que le dispositif selon l'invention, quel que soit son mode de réalisation, est réalisé à partir d'un mouvement d'horlogerie de type classique ne nécessitant aucune modification.It will be noted that the device according to the invention, whatever its embodiment, is made from a movement classic watchmaking requiring no modification.
