Abstract

A universal timepiece is corrected for a changed time zone by successive push button operations on a lever (11) pivoted at (A). Each operation corrects by one hour and is effected by a beak (30) which through gearing (28,29) and a supplementary hour wheel (27) turns the twenty four hour disk (3) anticlockwise and the hour hand (6) clockwise and also through a pin (15) which turns the city disk (1) anticlockwise

Description

Il existe de nombreuses pièces d'horlogerie affichant l'heure universelle, en particulier des montres-bracelets et des montres de poche. Le système d'heures universelles le plus couramment utilisé comporte une lunette tournante sur laquelle est inscrit le nom de vingt-quatre villes représentant chacune un fuseau horaire, ainsi qu'un disque de vingt-quatre heures numéroté de 1 à 24. Le disque de vingt-quatre heures est relié cinématiquement aux aiguilles de l'affichage horaire et tourne à raison d'un tour en vingt-quatre heures dans le sens anti-horaire. Ces pièces d'horlogerie permettent une lecture facile et instantanée de l'heure universelle car il n'y a aucune manipulation à effectuer. Il suffit en effet de chercher sur la lunette la ville dont on veut connaître l'heure et de lire ensuite le chiffre adjacent sur le disque de vingt-quatre heures. En revanche ces montres présentent l'inconvénient de devoir remettre la montre à l'heure lors d'un changement de fuseau horaire, manipulations qui peuvent être longues et compliquées et le temps s'écoulant pendant la manipulation n'est pas compté. Dans certains cas, cela nécessite une mise à l'heure subséquente. Un deuxième système d'heures universelles comprend également une lunette tournante comportant vingt-quatre villes, une aiguille centrale faisant un tour en vingt-quatre heures et qui est indépendante des aiguilles de l'affichage horaire, les chiffres de 1 à 24 faisant partie du cadran. L'inconvénient de ce système réside dans le fait d'une lecture indirecte de l'heure universelle. Il faut en effet repositionner la lunette pour connaître l'heure d'une ville à différents moments de la journée.There are many timepieces displaying universal time, especially wristwatches and pocket watches. The most commonly used universal time system has a rotating bezel with the names of twenty-four cities, each representing a time zone, and a twenty-four hour disc numbered from one to twenty-four. twenty-four hours is kinematically connected to the hands of the time display and rotates one turn in twenty-four hours in the counter-clockwise direction. These timepieces allow an easy and instantaneous reading of the universal time because there is no manipulation to perform. It is sufficient to look on the telescope for the city whose time you want to know, and then read the adjacent figure on the twenty-four hour disc. However, these watches have the disadvantage of having to put the watch back on time during a change of time zone, manipulations that can be long and complicated and the time flowing during handling is not counted. In some cases, this requires a subsequent time setting. A second system of universal hours also includes a rotating bezel with twenty-four cities, a central hand making a turn in twenty-four hours and which is independent of the hands of the time display, the numbers from 1 to 24 being part of the dial. The disadvantage of this system lies in the fact of an indirect reading of universal time. It is indeed necessary to reposition the telescope to know the time of a city at different times of the day.

Le but de la présente invention est d'offrir une pièce d'horlogerie obviant aux inconvénients précités, qui permette une lecture sans manipulation de l'heure universelle et dont la correction lors d'un changement de fuseau horaire soit la plus simple possible. La titulaire a mis au point un mécanisme permettant d'atteindre ce but, mécanisme décrit dans la demande de brevet allemand publiée No DE 197 16 693 . Une telle pièce d'horlogerie permettant un changement de fuseau horaire comporte un disque de vingt-quatre heures, un disque des villes rotatif et un mécanisme de correction reliant cinématiquement le disque de vingt-quatre heures, le disque des villes et l'aiguille des heures de manière à faire effectuer 1/24ème de tour dans le sens anti-horaire aux deux disques et à faire avancer l'aiguille des heures d'une heure pour chaque correction de fuseau horaire.The object of the present invention is to provide a timepiece obviating the aforementioned drawbacks, which allows a reading without manipulation of universal time and whose correction during a change of time zone is as simple as possible. The licensee has developed a mechanism to achieve this end, a mechanism described in the published German patent application No DE 197 16 693 . Such a timepiece allowing a change of time zone comprises a twenty-four hour disc, a city disc rotary and a correction mechanism kinematically connecting the disc of twenty-four hours, the city disc and the hour hand so as to perform 1 / 24th of a turn in the counterclockwise direction to both discs and to advance the Hour hand hour for each time zone correction.

Ce mécanisme présente la caractéristique que les déplacements des disques et de l'aiguille des heures sont obtenus à l'aide d'un ressort préalablement armé par un poussoir. Dans une telle construction, on est conduit à utiliser un ressort de grande dimension pour que la force du ressort soit suffisante pour mener à bien la correction sur les trois éléments mobiles.This mechanism has the characteristic that the movements of the disks and the hour hand are obtained using a spring previously armed by a pusher. In such a construction, one is led to use a large spring so that the force of the spring is sufficient to carry out the correction on the three movable elements.

La présente invention a pour but de remédier à cet inconvénient et a pour objet une pièce d'horlogerie telle que décrite dans la revendication 1.The present invention aims to overcome this drawback and relates to a timepiece as described in claim 1.

L'invention va maintenant être décrite en détail en référence au dessin annexé qui illustre à titre d'exemple le mécanisme de la pièce d'horlogerie à heures universelles.The invention will now be described in detail with reference to the accompanying drawing which illustrates by way of example the mechanism of the timepiece at universal times.

La figure 1 est une vue en plan de la montre objet de la présente invention affichant l'heure locale.The figure 1 is a plan view of the object of the present invention showing the local time.

La figure 2 illustre la montre de la figure 1 et le déplacement des différentes parties lors d'un changement de fuseau horaire.The figure 2 illustrates the watch of the figure 1 and moving the different parts during a time zone change.

La figure 3 illustre la montre des figures 1 et 2 une fois mise à l'heure suite à un changement de fuseau horaire.The figure 3 illustrates the watch Figures 1 and 2 once set due to a time zone change.

La figure 4 est une vue de dessus partiellement éclatée du mécanisme permettant la correction de fuseau horaire.The figure 4 is a partially exploded top view of the mechanism for time zone correction.

En référence aux figures 1 à 3, la montre comporte un disque extérieur 1 sur lequel est apposé le nom de vingt-quatre villes correspondant chacune à un fuseau horaire. Ce disque des villes 1 est muni de repères 2 représentés par exemple par un point noir, le repère représentant l'heure GMT situé sur le même fuseau horaire que Londres se présente par exemple sous la forme d'un point de couleur différente. Un second disque 3 des vingt-quatre heures présente une numérotation de 1 à 24. Le cadran 4 comporte à 12 heures un repère par exemple triangulaire 5 permettant d'indiquer à quelle ville correspond l'heure affichée par les aiguilles 6,7 de l'affichage horaire. La lecture de l'heure universelle est immédiate et ne nécessite aucune manipulation. Sur la figure 1, l'heure locale est de 12 heures et 15 minutes. Pour connaître l'heure de New York par exemple il suffit de trouver l'inscription New York sur le disque des villes 1 (à 9 heures) et de lire le chiffre correspondant sur le disque 3 des vingt-quatre heures, en l'occurrence 6. Ainsi à New York il est 6 heures et 15 minutes le matin, la minute étant universelle.With reference to Figures 1 to 3 , the watch has an outer disc 1 on which is affixed the name of twenty-four cities each corresponding to a time zone. This disk of the cities 1 is provided with marks 2 represented for example by a black dot, the mark representing the GMT time located on the same time zone as London is for example in the form of a different color point. A second disc 3 of twenty-four hours has a numbering from 1 to 24. The dial 4 comprises at 12 o'clock a triangular mark for example 5 to indicate to which city corresponds the time displayed by the hands 6,7 of the time display. Universal Time Reading is immediate and requires no manipulation. On the figure 1 the local time is 12 hours and 15 minutes. For the time of New York for example just find the inscription New York on the disc cities 1 (at 9 o'clock) and read the corresponding figure on the disc 3 of twenty-four hours, in this case 6. Thus in New York it is 6 hours and 15 minutes in the morning, the minute being universal.

Lorsque l'utilisateur change de fuseau horaire et désire mettre sa montre à l'heure, il suffit d'actionner le poussoir situé à 10 heures, représenté schématiquement par la flèche F, le nombre de fois nécessaire pour amener la ville correspondant au nouveau fuseau horaire à 12 heures en face du repère triangulaire 5 du cadran 4. A chaque pression sur le poussoir, le disque des villes 1 et le disque des vingt-quatre heures 3 tournent d'un 24/ème de tour dans le sens anti-horaire pendant que l'aiguille des heures 6 avance d'une heure. Sur la figure 3, après avoir actionné le poussoir 18 fois, la ville de New York est en face du repère triangulaire 5 et la montre indique l'heure locale à New York (6 heures et 15 minutes). On notera qu'il est toujours possible de connaître l'heure locale précédente (Paris) en lisant directement le chiffre sur le disque de vingt-quatre heures 3 en regard de Paris (12).When the user changes his time zone and wishes to put his watch on time, simply operate the pusher located at 10 o'clock, represented schematically by the arrow F, the number of times necessary to bring the city corresponding to the new time zone at 12 o'clock in front of the triangular mark 5 of the dial 4. Each time the pusher is pressed, the disc of the cities 1 and the disc of the twenty-four hours 3 turn 24 / th of a turn counterclockwise while the hour hand 6 advances one hour. On the figure 3 After pushing the pushbutton 18 times, New York City is in front of triangular mark 5 and the watch shows local time in New York (6 hours and 15 minutes). Note that it is always possible to know the previous local time (Paris) by reading directly the figure on the disc of twenty-four hours 3 opposite Paris (12).

La figure 4 illustre le mécanisme d'heures universelles. Ce mécanisme comporte un support de disque 8 vissé sur trois tubes de guidage 9,13 vissés dans la platine. Le support de disque 8 guide le disque des villes 1, ce dernier étant solidaire de l'étoile des villes 10. Un correcteur 11 dont le centre de rotation se trouve en A est actionné par l'intermédiaire d'un poussoir (non illustré) agissant sur un tenon 12 situé à 10 heures. Le centre de rotation A du correcteur 11 coopère avec une lumière L oblongue du correcteur 11 de sorte que lors d'une poussée sur le tenon 12 le correcteur 11 effectue d'abord une translation puis une rotation autour de A. Le correcteur 11 est ramené à sa position de repos contre le tube de guidage 9 grâce à un ressort de rappel 14. Une goupille 15 chassée dans un premier bras 11' du correcteur 11 travaille à un niveau supérieur avec la denture intérieure de vingt-quatre dents de l'étoile des villes 10. Ainsi, en actionnant le correcteur 11 par l'intermédiaire du tenon 12, le disque des villes effectue 1/24ème de tour dans le sens anti-horaire à chaque pression. Le sautoir des villes 16 pivote autour d'une bague chassée dans la platine en position B. Ce sautoir des villes 16 comporte un plot 17 muni de deux flancs 17', 17" formant un angle entre eux. Le plot 17 est solidaire du sautoir des villes 16 et en position de repos prend appui sur la denture de l'étoile des villes 10 et positionne de ce fait le disque des villes 1. Le sautoir 16 est ramené à sa position de repos par un ressort de rappel 18. Le plot 17 et la denture 10 du disque des villes forment un « tout ou rien » qui garantit que toutes les fonctions de la bascule 11 sont effectuées complètement. La fin de course de la bascule 11 est déterminée par l'entrée en contact du bec 11"' contre le tube de guidage 38.The figure 4 illustrates the mechanism of universal hours. This mechanism comprises a disk support 8 screwed onto three guide tubes 9,13 screwed into the plate. The disk carrier 8 guides the disk of the cities 1, the latter being secured to the star of the cities 10. A corrector 11 whose center of rotation is at A is actuated by means of a pusher (not shown). acting on a post 12 located at 10 o'clock. The center of rotation A of the corrector 11 cooperates with an oblong L light of the corrector 11 so that during a push on the post 12 the corrector 11 first performs a translation and then a rotation around A. The corrector 11 is brought back at its rest position against the guide tube 9 by means of a return spring 14. A pin 15 driven into a first arm 11 'of the corrector 11 works at a higher level with the internal teeth of twenty-four teeth of the star Thus, by actuating the corrector 11 via the post 12, the city disc performs 1/24 th of a turn in the counter-clockwise direction with each press. The jumper 16 cities pivots around a ring driven into the plate in position B. This jumper cities 16 comprises a stud 17 provided with two flanks 17 ', 17 "forming an angle between them.The stud 17 is secured to the jumper cities 16 and in the rest position is based on the toothing of the star of the cities 10 and thereby positions the disc of the cities 1. The jumper 16 is returned to its rest position by a return spring 18. The pad 17 and the toothing 10 of the disc of the cities form an "all or nothing" which ensures that all the functions of the rocker 11 are carried out completely The end of travel of the rocker 11 is determined by the contacting of the spout 11 "against the guide tube 38.

En fonctionnement normal de la pièce d'horlogerie, l'étoile des heures 24 est entraînée par la roue des heures par l'intermédiaire du sautoir des heures 25.In normal operation of the timepiece, the star of hours 24 is driven by the hour wheel via the hour jumper hours 25.

L'étoile des heures 24, solidaire de la roue supplémentaire des heures 27, entraîne cette dernière en rotation. La roue 27 engrène avec un renvoi 29 qui est fixé sur la roue de correction des heures 22 qui porte également un deuxième renvoi 28 qui engrène avec la dentition intérieure du disque des vingt-quatre heures 3. Ainsi, le disque des vingt-quatre heures 3 tourne en continu dans le sens inverse des aiguilles d'une montre à raison d'un tour par vingt-quatre heures. Du fait qu'il est dépendant de l'aiguille des heures 6, il est impossible de les décaler l'un par rapport à l'autre.The hour of hours 24, integral with the additional hour wheel 27, drives the latter in rotation. The wheel 27 meshes with a gear 29 which is attached to the hour correction wheel 22 which also carries a second gear 28 which meshes with the inner teeth of the twenty-four hour disc 3. Thus, the twenty-four hour disc 3 rotates continuously in the opposite direction of the clock at the rate of one turn per twenty-four hours. Because it is dependent on the hour hand 6, it is impossible to shift them relative to each other.

Pour permettre la correction des heures sans dérégler la mise à l'heure de l'aiguille des minutes 7, il faut rendre la roue supplémentaire des heures indépendante de la roue des heures pendant le changement de fuseau horaire. Ceci est résolu par l'utilisation d'un embrayage du type à étoile de 12 dents dont le principe est décrit en détail dans le brevet CH 340.191 au nom de la demanderesse. Cet embrayage comporte une étoile des heures de 12 dents 24 posée sur la roue des heures, un sautoir des heures 25 pivotant en D ainsi que son ressort de rappel 26. Cet ensemble est maintenu en hauteur par la roue supplémentaire des heures 27 et le pont P. Le sautoir des heures 25 s'appuie sur la denture de l'étoile des heures 24 qui porte l'aiguille des heures 6.To enable the correction of the hours without disturbing the time setting of the minute hand 7, it is necessary to make the additional hour wheel independent of the hour wheel during the change of time zone. This is solved by the use of a 12-star star type clutch whose principle is described in detail in the patent. CH 340.191 in the name of the plaintiff. This clutch comprises a star of hours 12 teeth 24 placed on the hour wheel, a jumper hours 25 pivoting D and its return spring 26. This assembly is maintained in height by the additional wheel hours 27 and the bridge P. The hours jumper 25 is based on the toothing of the hour star 24 which carries the hour hand 6.

Le correcteur 11, actionné par le tenon 12, comporte encore un second bras 11" sur l'extrémité duquel est pivoté un cliquet 30. Ce cliquet 30 est soumis à l'action d'un ressort 31 fixé sur le bras 11" du correcteur et présente un bec destiné à coopérer avec la denture en dents-de-loup de la roue de correction des heures 22.The corrector 11, actuated by the pin 12, further comprises a second arm 11 "on the end of which is pivoted a pawl 30. This pawl 30 is subjected to the action of a spring 31 fixed on the arm 11" of the corrector and presents a beak intended to cooperate with the teeth-of-wolf teeth of the hour correction wheel 22.

Ce bras 11" du correcteur 11 porte encore un second ressort 32 dont l'extrémité incurvée est destinée à être appliquée contre la denture en dents-de-loup de la roue de correction des heures 22 pour freiner celle-ci à la fin d'une correction de fuseau horaire.This arm 11 "of the corrector 11 still carries a second spring 32 whose curved end is intended to be applied against the teeth-of-wolf teeth of the hour correction wheel 22 to brake it at the end of a time zone correction.

Le mécanisme de correction comporte encore un frein 33 pivoté sur la goupille 34. Ce frein comporte un ressort 35 tendant à maintenir le frein en position active, le patin du frein 36 étant alors en contact avec la denture de la roue des heures, maintenant celle-ci en place et évitant que l'aiguille des minutes ne bouge lors de la correction.The correction mechanism further comprises a brake 33 pivoted on the pin 34. This brake comprises a spring 35 tending to maintain the brake in the active position, the brake pad 36 then being in contact with the toothing of the hour wheel, maintaining that in place and avoiding that the minute hand moves during the correction.

En position inactive de repos, ce frein est maintenu hors de contact d'avec la roue des heures par une goupille 37 agissant sur un levier 38 du frein 33. En fonctionnement normal de la pièce d'horlogerie, les freins 32 et 33 sont désactivés, le correcteur 11 étant maintenu en position de repos par son ressort de rappel 14.In the idle rest position, this brake is kept out of contact with the hour wheel by a pin 37 acting on a lever 38 of the brake 33. In normal operation of the timepiece, the brakes 32 and 33 are deactivated. , the corrector 11 being held in the rest position by its return spring 14.

La roue supplémentaire des heures 27, située au-dessus de la roue des heures est entraînée par celle-ci par l'intermédiaire de l'embrayage 25, et entraîne le disque de vingt-quatre heures 3.The additional hour wheel 27, located above the hour wheel is driven by the latter through the clutch 25, and drives the disc twenty-four hours.

Lorsque l'usager veut effectuer un changement de fuseau horaire, il appuie sur le tenon 12 à fond autant de fois qu'il veut changer de fuseau horaire.When the user wants to make a time zone change, he presses the pin 12 thoroughly as many times as he wants to change the time zone.

Par une pression sur le tenon 12, le correcteur 11 effectue d'abord une translation jusqu'à ce qu'il arrive en butée sur le tube de guidage A puis il pivote dans le sens contraire des aiguilles d'une montre ce qui provoque

  1. a. l'avancement du disque des villes 1 dans le sens anti-horaire d'un pas par la goupille 15 agissant sur la denture 10 de l'étoile des villes. Le sautoir 16 fixe pour chaque pas du disque des villes sa position stable.
  2. b. le cliquet 30 pivoté sur le bras 11" du correcteur entraîne par son bec la roue de correction des heures d'une valeur angulaire correspondant à une heure. La roue de correction des heures 22 entraîne d'une part le disque de vingt-quatre heures 3 par le renvoi 28 et d'autre part l'aiguille des heures par l'intermédiaire du renvoi 29 engrenant avec la roue supplémentaire des heures 27. Ainsi, le disque de vingt-quatre heures 3 et l'aiguille des heures 6 sont entraînés d'une valeur angulaire correspondant à une heure, l'un dans un sens anti-horaire et l'autre dans le sens horaire.
  3. c. Les freins 32 et 33 sont appliqués respectivement contre la denture de la roue de correction des heures 22 et la denture de la roue des heures . Le frein 32 permet d'éviter toute rotation de la roue de correction des heures dépassant la valeur angulaire désirée, correspondant à une heure, dépassement qui pourrait être dû à l'inertie du disque de vingt-quatre heures si le tenon 12 est activé brusquement.
    Ainsi, pour chaque pression du tenon 12, les deux disques 1,3 effectuent 1/24ème de tour dans le sens anti-horaire et l'aiguille des heures 6 avance d'une heure.
By pressing on the post 12, the corrector 11 first translates until it comes into abutment on the guide tube A and then rotates counterclockwise, which causes
  1. a . the advancement of the disc of the cities 1 in the anti-clockwise direction of a step by the pin 15 acting on the toothing 10 of the star of the cities. The jumper 16 fixed for each step of the disc cities its stable position.
  2. b . the pawl 30 pivoted on the arm 11 "of the corrector drives its hour-correction wheel by an hour-angle correction wheel corresponding to one hour, the hour correction wheel 22 causes the twenty-four hour disk, on the one hand, 3 by the reference 28 and on the other hand the hour hand via the gear 29 meshing with the wheel 27. Thus, the twenty-four hours disk 3 and the hour hand 6 are driven with an angular value corresponding to one hour, one in a counterclockwise direction and the other in the direction schedule.
  3. c . The brakes 32 and 33 are respectively applied against the toothing of the hour correction wheel 22 and the toothing of the hour wheel. The brake 32 makes it possible to avoid any rotation of the correction wheel hours exceeding the desired angular value, corresponding to one hour, exceeding which could be due to the inertia of the disc of twenty-four hours if the post 12 is activated suddenly .
    Thus, for each pressure of the tenon 12, the two disks 1.3 perform 1/24 th of a turn in the counter-clockwise direction and the hour hand 6 advances by one hour.
