Abstract

The rotary glass (12) has an inner array of teeth (34) driving a circular carrier (27) which is mounted rotatably on the axis (X) of the hour and minute hands (6,7). An auxiliary gear train on the carrier comprises a pedestal (22), an hour wheel (25) and minute works (23,24). The choice of transmission ratios ensures that the hour hand executes two complete revolutions for each one of the glass, which is engraved with designations of the 24 time zones throughout the world. The hands are reset conventionally (15).

Description

L'invention concerne une pièce d'horlogerie universelle, c'est-à-dire capable d'afficher l'heure sous différents fuseaux horaires, et plus particulièrement une montre bracelet dite montre universelle. Cette pièce d'horlogerie comporte au moins un indicateur des heures prévu pour effectuer un tour en douze heures et un indicateur des minutes prévu pour effectuer un tour en une heure, ainsi qu'un mouvement entraînant de manière conventionnelle l'indicateur des minutes et l'indicateur des heures, et un organe tournant indicateur d'au moins deux fuseaux horaires et entraînable manuellement en rotation. Les indicateurs des heures et des minutes peuvent être constitués d'aiguilles ou de disques.The invention relates to a universal timepiece, that is to say capable of displaying the time in different time zones, and more particularly a wristwatch known as a universal watch. This timepiece includes at least one hour indicator intended to perform a revolution in twelve hours and a minute indicator intended to perform a revolution in one hour, as well as a movement conventionally driving the minute indicator and the 'hour indicator, and a rotating member indicating at least two time zones and manually rotatable. The hour and minute indicators can be made up of hands or discs.

On connaît déjà des montres dont le bracelet porte des inscriptions indiquant le décalage horaire entre différents endroits de la planète. Grâce à ces indications l'utilisateur d'une telle montre, en actionnant sa couronne, peut amener les aiguilles dans la position correspondant à l'heure de n'importe lequel des fuseaux horaires. De façon complémentaire, la demande de brevet EP 0 461 547 décrit un indicateur de fuseaux horaires utilisable avec une telle montre. Cet indicateur est constitué d'un jeu de passants interchangeables portant chacun une indication géographique correspondant à l'un des vingt-quatre fuseaux horaires et destinés à être portés sélectivement sur le bracelet de la montre pour indiquer sur lequel fuseau horaire celle-ci est réglée. Une montre universelle particulièrement simple comme celle-ci présente des défauts. En effet, le changement d'heure, effectué à l'aide de la couronne de mise à l'heure, est une opération relativement laborieuse. L'utilisateur ne doit pas oublier l'heure initiale à laquelle il a commencé la manipulation, et de plus, pour ne pas perdre l'heure exacte il doit estimer de combien l'aiguille des minutes s'est déplacée pendant cette manipulation.Watches are already known whose strap bears inscriptions indicating the time difference between different places on the planet. Thanks to these indications, the user of such a watch, by actuating his crown, can bring the hands to the position corresponding to the time of any of the time zones. In addition, patent application EP 0 461 547 describes an indicator of time zones usable with such a watch. This indicator consists of a set of interchangeable passers-by each carrying a geographical indication corresponding to one of the twenty-four time zones and intended to be worn selectively on the watch strap to indicate on which time zone the latter is set. . A particularly simple universal watch like this has flaws. Indeed the change hour, performed using the time setting crown, is a relatively laborious operation. The user must not forget the initial time at which he started the manipulation, and moreover, in order not to lose the exact hour he must estimate how much the minute hand moved during this manipulation.

On connaît également de nombreuses pièces d'horlogerie ou montres universelles comportant des moyens permettant de régler la position de l'aiguille des heures sans que la progression normale de l'aiguille des minutes ne soit perturbée. Ce réglage de l'aiguille des heures est effectué soit en continu, soit par sauts. Le brevet DE 1 673 621, en particulier, décrit une montre dont le mouvement comporte un rouage planétaire reliant l'aiguille des minutes à celles des heures. Le positionnement de l'aiguille des heures peut être effectué en faisant tourner une cage portant la roue planétaire de ce rouage au moyen d'un poussoir et d'un encliquetage. Ce type de montre universelle présente également des défauts. En effet, le fait d'effectuer des changements d'heure sans déplacer l'aiguille des minutes peut donner à l'usager l'impression d'un intervalle de temps escamoté. De plus, si l'on désire obtenir une montre universelle de ce type à partir d'un mouvement d'horlogerie conventionnel, les modifications qu'il faut apporter à ce mouvement sont relativement nombreuses et délicates.Numerous timepieces or universal watches are also known, comprising means allowing the position of the hour hand to be adjusted without the normal progression of the minute hand being disturbed. This adjustment of the hour hand is carried out either continuously or in jumps. Patent DE 1 673 621, in particular, describes a watch the movement of which includes a planetary train connecting the minute hand to the hour hand. The positioning of the hour hand can be carried out by rotating a cage carrying the planetary wheel of this cog by means of a pusher and a snap. This type of universal watch also has faults. In fact, making time changes without moving the minute hand can give the user the impression of a retracted time interval. In addition, if one wishes to obtain a universal watch of this type from a conventional watch movement, the modifications which must be made to this movement are relatively numerous and delicate.

Le but de la présente invention est de fournir une pièce d'horlogerie ou montre universelle dans laquelle les indicateurs, en particulier les aiguilles, peuvent, par une opération très simple, être amenés dans une position correspondant à l'heure de n'importe quel fuseau horaire, cette pièce d'horlogerie pouvant de plus être réalisée facilement à partir d'un mouvement d'horlogerie classique et ordinaire.The object of the present invention is to provide a timepiece or universal watch in which the indicators, in particular the hands, can, by a very simple operation, be brought into a position corresponding to the time of any time. time zone, this timepiece can also be easily produced from a classic and ordinary timepiece movement.

La pièce d'horlogerie selon l'invention est caractérisée en ce qu'elle comprend un train d'engrenages auxiliaire situé à l'extérieur de la cage du mouvement, ce train d'engrenages étant composé d'une chaussée, d'une roue des heures et d'une minuterie et en ce que le mobile de minuterie est monté sur un support monté rotativement autour de l'axe de rotation des indicateurs et lié cinématiquement audit organe tournant de telle manière que l'entraînement en rotation de l'organe tournant indicateur des fuseaux horaires a pour effet d'entraîner l'indicateur des heures et l'indicateur des minutes en rotation à travers la minuterie.The timepiece according to the invention is characterized in that it comprises an auxiliary gear train located outside the movement cage, this gear train being composed of a carriageway, a wheel hours and a timer and in that the timer mobile is mounted on a support rotatably mounted around the axis of rotation of the indicators and kinematically linked to said rotating member so that the drive in rotation of the member Turning the time zone indicator causes the hour indicator and the minute indicator to rotate through the timer.

L'entraînement en rotation de l'organe tournant indicateur des fuseaux horaires, qui se présentera généralement sous la forme d'une lunette tournante, a par conséquent pour effet de faire tourner les indicateurs des heures et des minutes de la même manière que lors d'une mise à l'heure conventionnelle.The rotary drive of the time zone indicator rotating member, which will generally take the form of a rotating bezel, therefore has the effect of rotating the hour and minute indicators in the same manner as in '' a conventional time setting.

Le changement de fuseau horaire pourrait se faire par une rotation d'un angle quelconque de la lunette tournante mais en pratique, la montre sera généralement équipée d'une lunette tournante susceptible d'occuper vingt-quatre positions correspondant aux vingt-quatre fuseaux horaires, cette lunette tournante effectuant un tour complet pour deux tours de l'indicateur des heures. Lorsque cette lunette tournante effectue un demi-tour, l'indicateur des heures effectue un tour et le support rotatif de la minuterie effectue un tour et un onzième de tour.The time zone change could be done by a rotation of any angle of the rotating bezel but in practice, the watch will generally be equipped with a rotating bezel capable of occupying twenty-four positions corresponding to the twenty-four time zones, this rotating bezel making one complete revolution for two turns of the hour indicator. When this rotating bezel makes a half-turn, the hour indicator makes one turn and the rotary timer holder makes one turn and an eleventh turn.

Le mouvement d'horlogerie peut être aussi bien un mouvement mécanique, automatique ou non, qu'un mouvement électronique. Dans le cas d'un mouvement mécanique la mise à l'heure s'effectue de manière conventionnelle au moyen de la couronne de remontoir.The watch movement can be a mechanical movement, automatic or not, as well as an electronic movement. In the case of a mechanical movement, the time is set in a conventional manner by means of the winding crown.

Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'invention, ainsi qu'une variante de celle-ci.The accompanying drawing shows, by way of example, an embodiment of the invention, as well as a variant thereof.

La figure 1 est une vue de dessus d'une montre selon l'invention.Figure 1 is a top view of a watch according to the invention.

La figure 2 est une vue en coupe selon 3H - 9H de la montre représentée à la figure 1, mais dans laquelle les aiguilles des minutes et des heures ont été ramenées dans le plan du dessin pour une meilleure compréhension de celui-ci.Figure 2 is a sectional view along 3H - 9H of the watch shown in Figure 1, but in which the minute and hour hands have been brought back into the plane of the drawing for a better understanding thereof.

La figure 3 est une vue de dessus d'une variante d'exécution.Figure 3 is a top view of an alternative embodiment.

La montre représentée à la figure 1, repérée par la référence générale 1, comprend une boîte 2 logeant un cadran 4 devant lequel tourne une aiguille des heures 6 et une aiguille des minutes 7 autour d'un axe géométrique de rotation X (figure 2). Le cadran 4 porte des indications d'heures d'un type classique et il est protégé par une glace 8 qui est maintenue fixée dans le cran de glace d'une carrure-lunette 10. La montre 1 comporte de plus un organe indicateur de fuseaux horaires constitué d'une lunette tournante 12 dont la circonférence porte vingt-quatre graduations telles que la graduation 13 et vingt-quatre indications géographiques 14 correspondant aux vingt-quatre fuseaux horaires. La position de la lunette tournante 12 peut être repérée à l'aide d'un index fixe 5 apposé sur le cadran ou sur la glace. Les indications géographiques sont disposées dans un ordre tel que lorsqu'on parcourt la périphérie de la lunette tournante 12 dans le sens des aiguilles d'une montre, on se déplace autour de la terre d'Ouest en Est. Il sera naturellement possible de réaliser une montre sur lesquelles les indications géographiques sont disposées dans l'ordre inverse. La montre est en outre munie d'une couronne usuelle de remontoir 15.The watch shown in Figure 1, identified by the general reference 1, includes a box 2 housing a dial 4 in front of which rotates an hour hand 6 and a minute hand 7 around a geometric axis of rotation X (Figure 2) . The dial 4 carries time indications of a conventional type and is protected by a lens 8 which is kept fixed in the notch of a middle part of the bezel 10. The watch 1 further comprises a time indicator timetable consisting of a rotating bezel 12 whose circumference carries twenty-four graduations such that the graduation 13 and twenty-four geographical indications 14 corresponding to the twenty-four time zones. The position of the rotating bezel 12 can be identified using a fixed index 5 affixed to the dial or to the crystal. The geographical indications are arranged in an order such that when one traverses the periphery of the rotating bezel 12 clockwise, one moves around the earth from West to East. It will naturally be possible to make a watch on which the geographical indications are arranged in reverse order. The watch is furthermore provided with a usual winding crown 15.

La carrure-lunette 10 est elle-même entourée d'une carrure annulaire 16, la lunette tournante 12 étant retenue entre cette carrure annulaire extérieure 16 et une portée de la carrure-lunette 10. La lunette tournante 12 peut occuper vingt-quatre positions dans lesquelles elle est maintenue par une encliquetage constitué d'un cliquet vertical 17 monté dans la carrure annulaire 16 et poussé par un ressort 18, ce cliquet 17 coopérant avec vingt-quatre creux 19 de la lunette tournante 12. Sur la carrure 16 est fixé un fond de boîte 19.The middle part of the bezel 10 is itself surrounded by an annular middle part 16, the rotating bezel 12 being retained between this outer annular middle part 16 and a range of the middle bezel 10. The rotating bezel 12 can occupy twenty-four positions in which it is held by a snap consisting of a vertical pawl 17 mounted in the annular middle part 16 and pushed by a spring 18, this pawl 17 cooperating with twenty-four recesses 19 of the rotating bezel 12. On the middle 16 is fixed a case back 19.

La montre est équipée d'un mouvement 20, par exemple un mouvement mécanique. Ce mouvement 20 ne se distingue d'un mouvement standard que par le fait que sa chaussée 35 est raccourcie, et présente une denture 36 ou un crabot à son extrémité supérieure. La montre est par contre équipée d'un train d'engrenages auxiliaire monté à l'extérieur de la cage du mouvement, train d'engrenages constitué d'une chaussée auxiliaire 22 montée rotativement sur un chevillot 21 fixé au pignon de centre (non représenté), d'une roue de minuterie 23 avec son pignon de minuterie 24 et d'une roue des heures avec son canon 25a situés entre la cage du mouvement et le cadran 4. L'extrémité inférieure de la chaussée auxiliaire 21 est munie d'une denture ou autre crabot venant en prise avec la denture 36 de la chaussée principale 35 de telle manière que les deux chaussées sont solidaires en rotation. En outre la cheville 26, sur laquelle est monté le mobile de minuterie 23/24, est fixé sur un support 27 monté rotativement dans la boîte autour de l'axe X. Ce support 27 se présente sous la forme d'une pièce circulaire munie d'une couronne dentée 28 et présentant un creusure 29 dans laquelle sont logés les mobiles 22 à 25. Cette creusure est fermée par une plaque 30 fixée sur le support rotatif 27. Ce support 27 est lui-même supporté rotativement par une bague fixe 31 supportant le cadran 4. La couronne dentée 28 est en prise avec un premier renvoi 32 lui-même en prise avec un second renvoi 33, identique au renvoi 32, ces deux renvois étant pivotés sur la bague fixe 31. Le renvoi 33 est lui-même en prise avec une denture radiale 34 formée sur le côté intérieur de la lunette tournante 12. La denture 34 présente cent-quarante-quatre dents et la couronne dentée 28 soixante-six dents. Lorsqu'on entraîne en rotation la lunette tournante 12, le support tournant 27 est ainsi entraîné en rotation dans le même sens que la lunette tournante 12 en raison des deux renvois 32 et 33, avec un rapport de transmission égal à 144/66 ou 24/11.The watch is equipped with a movement 20, for example a mechanical movement. This movement 20 is distinguished from a standard movement only by the fact that its pavement 35 is shortened, and has a toothing 36 or a dog clutch at its upper end. The watch is on the other hand equipped with an auxiliary gear train mounted outside the movement cage, gear train consisting of an auxiliary carriage 22 rotatably mounted on a pin 21 fixed to the pinion center (not shown), a timer wheel 23 with its timer pinion 24 and an hour wheel with its barrel 25a located between the movement cage and the dial 4. The lower end of the auxiliary road 21 is provided with a toothing or other dog clutch engaging the toothing 36 of the main carriageway 35 so that the two carriageways are integral in rotation. In addition, the dowel 26, on which the timer mobile 23/24 is mounted, is fixed on a support 27 rotatably mounted in the box around the axis X. This support 27 is in the form of a circular part provided a toothed ring 28 and having a recess 29 in which the mobiles 22 to 25 are housed. This recess is closed by a plate 30 fixed on the rotary support 27. This support 27 is itself rotatably supported by a fixed ring 31 supporting the dial 4. The toothed crown 28 is engaged with a first reference 32 itself engaged with a second reference 33, identical to the reference 32, these two references being pivoted on the fixed ring 31. The reference 33 is itself even in engagement with a radial toothing 34 formed on the inner side of the rotating bezel 12. The toothing 34 has one hundred and forty-four teeth and the toothed crown 28 sixty-six teeth. When the rotating bezel 12 is rotated, the rotating support 27 is thus rotated in the same direction as the rotating bezel 12 due to the two references 32 and 33, with a transmission ratio equal to 144/66 or 24 / 11.

Une rotation de la lunette tournante 12 a ainsi pour effet d'entraîner la minuterie 23/24 en rotation autour du chevillot 26 et autour de l'axe X. La liaison cinématique entre la lunette tournante 12 et le support rotatif 27 est telle que lorsque la lunette tournante 12 effectue un tour, le support rotatif 27 effectue deux tours et deux onzièmes de tour et l'aiguille des heures effectue deux tours. Si l'on se réfère à un tour de cadran de l'aiguille des heures, c'est-à-dire douze heures, ce qui correspond à un demi-tour de la lunette tournante 12, le support rotatif 27 effectue un tour et un onzième de tour. Il convient de souligner que l'aiguille des heures est entraînée par l'intermédiaire de la minuterie et que l'aiguille des minutes tourne normalement comme lors d'une mise à l'heure conventionnelle. Lorsqu'on fait tourner la lunette tournante 12 dans le sens horaire, c'est-à-dire dans le sens croissant des fuseaux horaires, dont les indications passent successivement devant l'index 5, les aiguilles 6 et 7 tournent dans le même sens. L'avance d'un fuseau horaire, c'est-à-dire la rotation de la lunette tournante 12 de 1/24 tour a pour effet de faire tourner le support mobile 27 de 1/11 tour et l'aiguille des heures de 1/12 tour. La rotation des aiguilles est ainsi obtenue par une rotation du support 27 légèrement plus rapide que la rotation de la roue des heures 25.A rotation of the rotating bezel 12 thus has the effect of driving the timer 23/24 in rotation around the pin 26 and around the axis X. The kinematic connection between the rotating bezel 12 and the support 27 is such that when the rotating bezel 12 makes one turn, the rotary support 27 makes two turns and two elevenths of a turn and the hour hand makes two turns. If one refers to a revolution of the dial of the hour hand, that is to say twelve hours, which corresponds to a half-revolution of the rotating bezel 12, the rotary support 27 performs one revolution and an eleventh turn. It should be noted that the hour hand is driven via the timer and that the minute hand turns normally as when setting a conventional time. When the rotating bezel 12 is rotated clockwise, that is to say in the ascending direction of the time zones, the indications of which pass successively in front of the index 5, the hands 6 and 7 rotate in the same direction . The advance of a time zone, that is to say the rotation of the rotating bezel 12 by 1/24 turn has the effect of rotating the movable support 27 by 1/11 turn and the hour hand of 1/12 turn. The rotation of the hands is thus obtained by a rotation of the support 27 slightly faster than the rotation of the hour wheel 25.

La mise à l'heure s'effectue de manière conventionnelle au moyen de la couronne de remontoir 15. On constate que le pignon de minuterie et la roue des heures du mouvement standard pourraient être supprimés puisque l'entraînement de l'aiguille des heures s'effectue par la minuterie auxiliaire 25, ce qui permettrait de réduire l'épaisseur du mouvement 20.The time setting is carried out in a conventional manner by means of the winding crown 15. It can be seen that the timer pinion and the hour wheel of the standard movement could be omitted since the driving of the hour hand s 'performed by the auxiliary timer 25, which would reduce the thickness of the movement 20.

La construction décrite nécessite un minimum d'intervention sur les mouvements existants. Dans le même esprit les deux chaussées pourraient être rendues solidaires en rotation par d'autres moyens, par exemple par une pièce auxiliaire de liaison.The construction described requires a minimum of intervention on existing movements. In the same spirit, the two roads could be returned integral in rotation by other means, for example by an auxiliary connecting part.

Il serait cependant également possible de remplacer les deux chaussées par une chaussée unique en remplaçant la chaussée d'origine du mouvement par une chaussée plus longue munie d'une denture additionnelle.However, it would also be possible to replace the two pavements with a single pavement by replacing the original pavement of the movement with a longer pavement provided with additional teeth.

Il serait également possible de remplacer le pignon de centre d'origine par un pignon de centre muni d'une tige plus longue remplaçant le chevillot 21.It would also be possible to replace the original center pinion with a center pinion provided with a longer rod replacing the pin 21.

La figure 3 représente une variante d'exécution dans laquelle les indication géographiques 66 correspondant aux différents fuseaux horaires sont apposées sur la glace 8, la lunette tournante 12 étant simplement munie de deux index 68, 69 situés à quinze degrés l'un de l'autre, l'index 69 correspondant à l'heure d'été et l'index 68 à l'heure d'hiver. Lorsque par exemple, la montre est réglée sur l'heure d'été de Paris, comme c'est le cas sur la figure 3, on passe à l'heure d'hiver de Paris en faisant tourner simplement la lunette 12 de manière à amener l'index 68 devant l'indication "Paris".FIG. 3 represents an alternative embodiment in which the geographical indications 66 corresponding to the different time zones are affixed to the crystal 8, the rotating bezel 12 being simply provided with two indices 68, 69 located fifteen degrees from one of the other, index 69 corresponding to summer time and index 68 to winter time. When, for example, the watch is set to Paris summer time, as is the case in FIG. 3, we switch to Paris winter time by simply rotating the bezel 12 so as to bring the index 68 in front of the indication "Paris".
