Description

La présente invention est relative à un organe de mise à l'heure d'un indicateur d'heures d'une pièce d'horlogerie, cet indicateur étant entraîné en usage normal par un mécanisme commandé par le rouage que comporte ladite pièce, ce mécanisme étant arrangé pour désolidariser ledit rouage dudit indicateur quand l'organe de mise à l'heure est actionné, cette action faisant alors avancer l'indicateur d'un pas d'une heure.The present invention relates to a time-setting member of a time indicator of a timepiece, this indicator being driven in normal use by a mechanism controlled by the gearing of said workpiece, this mechanism being arranged to disengage said work train from said indicator when the time setting member is actuated, which action then advances the indicator by one hour step.

Un tel dispositif est connu et décrit dans le document EP - A - 1'544'691 . Dans ce document la pièce d'horlogerie comprend une aiguille des heures susceptible d'être avancée par pas d'une heure au moyen d'une tige de mise à l'heure actionnée manuellement sans affecter l'affichage des minutes. Pour cela cette aiguille des heures est constamment couplée au rouage de finissage c'est-à-dire à l'élément moteur que porte la pièce d'horlogerie sauf au moment de la mise à l'heure où cette aiguille est désolidarisée du rouage, la rotation de la tige permettant alors d'avancer d'une heure ladite aiguille. Ce système permet de ne pas toucher aux décimales de l'heure qui restent conservées. Par exemple si l'aiguille d'heure indique 10 heures 30 minutes, la rotation de la tige fera avancer cette aiguille à 11 heures 30 minutes.Such a device is known and described in the document EP - A - 1,544,691 . In this document the timepiece comprises an hour hand capable of being advanced in steps of one hour by means of a manually set time-setting rod without affecting the display of minutes. For this purpose, the hour hand is constantly coupled to the work train, that is to say to the motor element that the timepiece wears except at the time of setting the time when this needle is detached from the gear train, the rotation of the rod then allowing to advance one hour said needle. This system makes it possible not to touch the decimals of the hour which remain preserved. For example if the hour hand indicates 10 hours 30 minutes, the rotation of the rod will advance this needle to 11 hours 30 minutes.

Pour parvenir à ce résultat la pièce d'horlogerie décrite dans le document cité ci-dessus comporte une première roue engrenant avec le rouage et une seconde roue susceptible d'être entraînée par la tige au moment de la mise à l'heure. Les roues sont couplées entre elles par un mécanisme à couple limité incluant un ressort. On comprendra qu'en dehors des périodes où l'on corrige l'heure les première et seconde roues restent rigidement accouplées ce qui permet de modifier l'affichage de l'heure sans toucher aux minutes qui complètent cette heure.To achieve this result the timepiece described in the document cited above comprises a first wheel meshing with the wheel and a second wheel may be driven by the rod at the time of setting the time. The wheels are coupled together by a limited torque mechanism including a spring. It will be understood that, apart from the periods when the time is corrected, the first and second wheels remain rigidly coupled, which makes it possible to modify the display of the time without touching the minutes that complete this time.

Obtenir les mêmes résultats, non plus à partir d'une tige que l'on tourne mais à partir d'un bouton poussoir que l'on presse présente une avancée technique intéressante car elle permet de proposer une pièce d'horlogerie nouvelle à combinaisons inconnues à ce jour.Obtaining the same results, no longer from a rod that is rotated but from a push button that is pressed presents an interesting technical advance because it allows to propose a new timepiece with unknown combinations nowadays.

On sait utiliser un bouton poussoir pour corriger certaines unités temporelles. C'est le cas pour l'affichage de la date ou du jour de la semaine où l'on met en oeuvre par exemple un doigt d'actionnement qui entraîne la denture d'un anneau sur lequel est affiché la date ou le jour de la semaine qui apparaît au travers d'un guichet. Il s'agit cependant ici du simple passage d'un chiffre à l'autre, soit d'une avancée pas à pas où il n'y a pas lieu de prendre en compte une fraction ou une décimale de ce chiffre.It is known to use a push button to correct certain time units. This is the case for the display of the date or the day of the week where it implements for example an actuating finger which causes the toothing of a ring on which is displayed the date or the day of the week that appears through a window. However, this is a simple transition from one digit to another, not where there is no need to take into account a fraction or a decimal of this figure.

Ainsi l'organe de mise à l'heure d'un indicateur d'heures selon la présente invention, en plus que cet indicateur obéit à ce qui est exposé dans le premier paragraphe de cette description est remarquable en ce qu'il comporte un bouton poussoir qui, lorsqu'il subit une pression manuelle, actionne un dispositif agissant à son tour sur ledit mécanisme pour désolidariser ledit rouage dudit indicateur.Thus the time setting member of an hour indicator according to the present invention, in addition that this indicator obeys what is explained in the first paragraph of this description is remarkable in that it comprises a button pusher which, when subjected to manual pressure, actuates a device acting in turn on said mechanism to disengage said gear of said indicator.

L'invention va maintenant être expliquée en détail ci-dessous par un mode d'exécution donné à titre d'exemple, cet exemple étant donné à titre purement illustratif et non limitatif seulement, cette exécution étant illustrée par les dessins annexés dans lesquels:

  • la figure 1 est une vue de dessus générale montrant une pièce d'horlogerie équipée d'un organe de mise à l'heure selon l'invention;
  • la figure 2 est une vue en plan d'un mode d'exécution du mécanisme exécuté selon l'invention;
  • la figure 3 est une coupe selon la ligne III - III tracée en figure 2;
  • la figure 4 est une coupe selon la ligne IV - IV tracée en figure 2;
  • les figures 5 à 8 explicitent quatre situations du mécanisme pour expliquer le fonctionnement du changement d'heure selon l'invention quand on actionne le bouton poussoir de commande, et
  • la figure 9 est un agrandissement de la zone IX tracée en figure 7.
The invention will now be explained in detail below by an embodiment given by way of example, this example being given for purely illustrative and non-limiting purposes only, this embodiment being illustrated by the appended drawings in which:
  • the figure 1 is a general top view showing a timepiece equipped with a time-setting member according to the invention;
  • the figure 2 is a plan view of an embodiment of the mechanism executed according to the invention;
  • the figure 3 is a section along line III - III drawn in figure 2 ;
  • the figure 4 is a section along line IV - IV drawn in figure 2 ;
  • the Figures 5 to 8 explain four situations of the mechanism for explaining the operation of the time change according to the invention when the control push button is actuated, and
  • the figure 9 is an enlargement of zone IX drawn in figure 7 .

La figure 1 est une vue de dessus d'une pièce d'horlogerie incluant la présente invention, plus précisément un affichage rétrograde de l'heure sur 24 heures. L'indicateur d'heures est une aiguille 2 surmontant une graduation 35 disposée en arc de cercle et s'étendant entre 0 et 24. Cette pièce d'horlogerie peut être appelée montre à fuseau, l'heure locale du lieu où le porteur de la montre réside habituellement étant affichée par l'aiguille 2 et l'heure du fuseau du lieu où le porteur de la montre séjourne temporairement étant affichée par une aiguille 36, cette aiguille étant complétée par une aiguille des minutes 37. La montre de la figure 1 est complétée par un affichage de la date 38, du jour de la semaine 39 et d'une petite seconde 40. La mise à l'heure de l'aiguille 2 est effectuée au moyen d'un bouton poussoir 5. D'autres dispositions peuvent être envisagées, l'intérêt présent se focalisant sur l'aiguille 2 mise à l'heure par le bouton poussoir 5.The figure 1 is a top view of a timepiece including the present invention, more specifically a retrograde display of the hour over 24 hours. The hour indicator is a needle 2 surmounting a graduation 35 arranged in an arc and extending between 0 and 24. This timepiece can be called a spindle watch, the local time of the place where the wearer of the watch usually resides being displayed by the hand 2 and the time of the spindle of the place where the wearer of the watch temporarily stays being displayed by a needle 36, this needle being completed by a minute hand 37. The watch of the figure 1 is completed by a display of the date 38, the day of the week 39 and a small second 40. The setting time of the needle 2 is performed by means of a push button 5. Other provisions can be envisaged, the present interest being focused on the needle 2 set by the push button 5.

La figure 2 est une vue en plan du mécanisme d'affichage de l'heure avec son organe de mise à l'heure selon l'invention. Sur cette figure est représenté un indicateur d'heures 2, en l'occurrence une aiguille, susceptible d'être mise à l'heure par un organe 1. L'indicateur 2 est entraîné en usage normal par un mécanisme 3, ce dernier étant commandé par le rouage 4 inclus dans la pièce d'horlogerie. Le mécanisme 3 est arrangé pour désolidariser le rouage 4 de l'indicateur 2 quand l'organe de mise à l'heure 1 est actionné, cette action faisant alors avancer l'indicateur d'un pas d'une heure.The figure 2 is a plan view of the time display mechanism with its time setting member according to the invention. In this figure is represented an indicator of hours 2, in this case a needle, which can be set by an hour 1. The indicator 2 is driven in normal use by a mechanism 3, which last being controlled by the gear train 4 included in the timepiece. The mechanism 3 is arranged to separate the gear 4 of the indicator 2 when the time setting member 1 is actuated, this action then advancing the indicator by one hour step.

Ce qui vient d'être expliqué présente une originalité qui, selon l'invention, consiste à mettre en oeuvre un bouton poussoir 5 en guise d'organe de mise à l'heure 1 de l'indicateur 2. Toujours selon l'invention, ce bouton poussoir, lorsqu'il subit une pression manuelle, actionne un dispositif 6 qui agit à son tour sur le mécanisme 3 pour désolidariser le rouage 4 de l'indicateur 2 et faire avancer ainsi l'indicateur 2 d'un pas d'une heure.What has just been explained presents an originality which, according to the invention, consists in implementing a push button 5 as time setting member 1 of the indicator 2. Still according to the invention, this push button, when it undergoes a manual pressure, actuates a device 6 which in turn acts on the mechanism 3 to separate the gear 4 of the indicator 2 and thus advance the indicator 2 by a step of a hour.

D'une manière générale le mécanisme 3 comporte une première roue 7 commandée par le rouage 4 et engrenant sur lui, et une seconde roue 8. Cette seconde roue 8 est couplée d'une part à la première roue 7 au moyen d'un dispositif à ressort 9 et entraînée d'autre part par le dispositif 6 actionné par le bouton poussoir 5 quand ce dernier est activé pour désolidariser les première et seconde roues l'une de l'autre et faire avancer d'un pas l'indicateur d'heures 2.In general, the mechanism 3 comprises a first wheel 7 controlled by the gear 4 and meshing with it, and a second wheel 8. This second wheel 8 is coupled on the one hand to the first wheel 7 by means of a device spring 9 and driven on the other hand by the device 6 actuated by the push button 5 when the latter is activated to separate the first and second wheels from each other and to advance a step the indicator of hours 2.

Plus précisément et comme le montrent bien la figure 3 qui est une coupe selon la ligne III - III tracée en figure 2 et la figure 4 qui est une coupe selon la ligne IV - IV tracée en figure 2, la première roue 7 est emmanchée à force sur une couronne 10 tournant librement sur un moyeu 11. La couronne 10 présente une étoile 12 pourvue d'autant de dents 13 que l'indicateur montre de divisions horaires 35 (voir figure 2). Deux vides diamétralement opposés de l'étoile 12 coopèrent respectivement avec deux saillies 14 que présente un ressort annulaire 15 entourant l'étoile 12. Ce ressort 15 porte deux retours verticaux 16 qui plongent dans deux lumières correspondantes 17 pratiquées dans une planche 18 forcée sur le moyeu 11. Les figures 3 et 4 montrent encore que la seconde roue 8 est emmanchée à force sur le moyeu 11 et qu'elle est susceptible d'engrener avec le dispositif 6 actionné par le bouton poussoir 5 comme cela sera décrit en détail plus loin. L'indicateur d'heures 2 est entraîné par le moyeu 11. Selon la nature de cet indicateur cet entraînement pourra se faire de deux façons dont une va être décrite maintenant.More precisely and as the figure 3 which is a section along line III - III drawn in figure 2 and the figure 4 which is a section along line IV - IV drawn in figure 2 , the first wheel 7 is force-fitted on a ring 10 freely rotating on a hub 11. The ring 10 has a star 12 provided with as many teeth 13 as the indicator shows of time divisions 35 (see FIG. figure 2 ). Two diametrically opposite voids of the star 12 cooperate respectively with two projections 14 that has an annular spring 15 surrounding the star 12. This spring 15 carries two vertical returns 16 which dive into two corresponding slots 17 formed in a plate 18 forced on the hub 11. The Figures 3 and 4 show again that the second wheel 8 is force-fitted on the hub 11 and that it is capable of meshing with the device 6 actuated by the push button 5 as will be described in detail below. The hour indicator 2 is driven by the hub 11. Depending on the nature of this indicator this training can be done in two ways, one of which will be described now.

Les figures 2 et 4 montrent que sur le moyeu 11 est emmanchée à force une came 19 sur laquelle frotte un palpeur 20 situé à l'extrémité d'un râteau 21. L'autre extrémité de ce râteau est pourvue d'une denture 22. Le râteau est articulé en 41. La denture 22 du râteau 21 engrène avec un pignon 23 sur l'axe duquel est fixé un indicateur rétrograde de l'heure 2.The figures 2 and 4 show that on the hub 11 is force-fitted a cam 19 on which rubs a feeler 20 located at the end of a rake 21. The other end of this rake is provided with a toothing 22. The rake is hinged in 41. The toothing 22 of the rake 21 meshes with a pinion 23 on the axis of which is fixed a retrograde indicator of the hour 2.

L'indicateur d'heures 2 pourrait être emmanché directement sur le moyeu 11. On aurait alors une aiguille évoluant en rotation continue sur le cadran de la pièce d'horlogerie. Cette situation n'est pas représentée sur le dessin.The hour indicator 2 could be fitted directly on the hub 11. It would then have a needle rotating in continuous rotation on the dial of the timepiece. This situation is not represented in the drawing.

On a parlé à plusieurs reprises ci-dessus du rouage 4 de la pièce d'horlogerie, ce rouage entraînant la première roue 7 faisant partie du mécanisme 3. Par rouage, appelé aussi finissage dans le langage horloger, on entend le train d'engrenages directement lié à l'élément moteur de la pièce d'horlogerie, cet élément moteur consistant principalement en un barillet à ressort. Dans la construction prise ici en exemple ce rouage 4 aboutit à une roue des heures 42 sur laquelle est fixée une aiguille des heures 36 (voir figures 1, 2 et 4). L'aiguille des heures 36 fait un tour en 12 heures et la roue 42 qui lui est liée engrène sur un renvoi 43 qui entraîne à son tour la première roue 7 du mécanisme 3. Le rapport d'engrenage est arrangé de telle façon que la roue 7 fasse un tour en 24 heures ce qui conduit à un affichage sur 24 heures de l'indicateur 2. Cette première roue 7 est donc liée en permanence au rouage 4 de la pièce d'horlogerie de sorte que si le bouton poussoir 5 est actionné, l'indicateur 2 avance d'un pas d'une heure en conservant la fraction d'heure existant avant la correction.We have spoken several times above of the wheel 4 of the timepiece, this wheel driving the first wheel 7 forming part of the mechanism 3. By gear, also called finishing in the watchmaking language, we mean the gear train directly related to the motor element of the timepiece, this motor element consisting mainly of a spring barrel. In the construction taken here as an example this wheel 4 leads to an hour wheel 42 on which is fixed an hour hand 36 (see FIG. Figures 1, 2 and 4 ). The hour hand 36 makes a turn in 12 hours and the wheel 42 which is linked to it meshes with a reference 43 which in turn drives the first wheel 7 of the mechanism 3. The gear ratio is arranged in such a way that the wheel 7 make a turn in 24 hours which leads to a 24-hour display of the indicator 2. This first wheel 7 is therefore permanently linked to the wheel 4 of the timepiece so that if the push button 5 is When pressed, the indicator 2 advances one step by one hour, keeping the fraction of an hour existing before the correction.

Les figures 2 et 3 montrent un exemple de dispositif 6 actionné par le bouton poussoir 5 et agissant sur le mécanisme 3 pour désolidariser le rouage 4 de l'indicateur 2. Ce dispositif 6 comporte une roue baladeuse 24 dont la denture 25 entre en prise avec la seconde roue 8 quand le bouton poussoir est actionné. Cette roue baladeuse 24 porte un pignon 26 dont la denture engrène avec la denture 27 d'un râteau 28, ce dernier étant commandé par le bouton poussoir 5. Dans l'exemple de construction montré aux dessins 2 et 3 cette commande est réalisée par l'intermédiaire d'une bascule intercalaire 44, mais pourrait être réalisée directement. Sur le râteau, articulé en 45, agit un ressort de rappel 46.The figures 2 and 3 show an example of device 6 actuated by the push button 5 and acting on the mechanism 3 to disconnect the gear 4 of the indicator 2. This device 6 comprises a wheel 24 whose gear teeth 25 engages the second wheel 8 when the push button is pressed. This wheel 24 carries a pinion 26 whose teeth mesh with the toothing 27 of a rake 28, the latter being controlled by the push button 5. In the example of construction shown in drawings 2 and 3 this control is carried out by the intermediate of an intermediate rocker 44, but could be carried out directly. On the rake, hinged at 45, acts a return spring 46.

Les figures 5 à 8 montrent quatre situations dans le cycle de mise à l'heure de l'indicateur 2 et la figure 9 est un agrandissement de la zone IX tracée en figure 7. On va expliquer maintenant, à l'aide des figures 5 à 9, comment fonctionne le mécanisme de mise à l'heure quand on exerce une pression sur le bouton poussoir 5 pour faire passer l'indicateur d'heures d'une heure à l'autre. Les références chiffrées sont les mêmes que celles utilisées sur la figure 2.The Figures 5 to 8 show four situations in the time-stamping cycle of indicator 2 and the figure 9 is an enlargement of zone IX drawn in figure 7 . We will explain now, with the help of Figures 5 to 9 how does the time-setting mechanism operate when pushing the push-button 5 to move the hour indicator from one hour to the other. The numerical references are the same as those used on the figure 2 .

La figure 5 montre une pièce d'horlogerie en fonctionnement normal. Le bouton poussoir 5 est au repos, entièrement relâché. Le râteau 28 se trouve repoussé en fin de course vers l'extérieur de la pièce d'horlogerie par le ressort de rappel 46. Engrenant avec ce râteau la roue baladeuse 24 se trouve totalement désengagée de la seconde roue 8 du mécanisme 3. L'indicateur 2 lié au pignon 23 indique 0 heure 30 minutes, le palpeur 20 du râteau 21 se trouvant dans la région du plus petit diamètre de la came 19.The figure 5 shows a timepiece in normal operation. The push button 5 is at rest, fully released. The rake 28 is pushed back towards the outside of the timepiece by the return spring 46. In this rake, the wiper wheel 24 is completely disengaged from the second wheel 8 of the mechanism 3. indicator 2 linked to gear 23 indicates 0 hour 30 minutes, the probe 20 of the rake 21 being in the region of the smallest diameter of the cam 19.

La figure 6 montre le même mécanisme avec un bouton poussoir 5 enfoncé à mi-course. Le râteau 28 a basculé dans le sens horaire poussé qu'il est par la bascule intercalaire 44. La denture 27 du râteau 28 a entraîné la roue baladeuse 24 par son pignon 26 dans un mouvement de translation jusqu'à ce que la denture 25 de la roue 24 se trouve en prise avec la denture de la seconde roue 8 du mécanisme 3. La roue baladeuse 24 porte un arbre 29 qui est guidé dans un trou oblong 30 qui n'est pas représenté à la figure 6 mais qui est dessiné à la figure 9. Ce mouvement de translation est effectué sans rotation de la roue 24, la rotation étant empêchée par un ressort de friction 31 qui appuie sur la planche de la roue 24. Dans cette situation l'arbre 29 de la roue 24 se trouve en butée au fond du trou oblong 30 et la roue 8 se trouve toujours dans la même position angulaire que celle représentée en figure 5. L'indicateur d'heures affiche toujours 0 heure 30 minutes.The figure 6 shows the same mechanism with a push button 5 pressed halfway. The rake 28 has rotated clockwise as it is by the intermediate rocker 44. The toothing 27 of the rake 28 has driven the wheel 24 by its pinion 26 in a translational movement until the tooth 25 of the wheel 24 is engaged with the toothing of the second wheel 8 of the mechanism 3. The wheel 24 carries a shaft 29 which is guided in an oblong hole 30 which is not shown in FIG. figure 6 but which is drawn to the figure 9 . This translational movement is carried out without rotation of the wheel 24, the rotation being prevented by a friction spring 31 which bears on the board of the wheel 24. In this situation the shaft 29 of the wheel 24 is in abutment at the bottom oblong hole 30 and the wheel 8 is always in the same angular position as that shown in FIG. figure 5 . The hour indicator always displays 0 hours 30 minutes.

Les figures 7 et 9 montrent le même mécanisme avec un bouton poussoir 5 enfoncé aux deux tiers de sa course totale. La roue baladeuse 24 a commencé à tourner dans le sens antihoraire A entraînée en rotation par l'action de la denture 27 du râteau 28 sur le pignon 26 de ladite roue 24 (voir figure 9). La rotation de la roue baladeuse 24 a fait tourner la seconde roue 8 du mécanisme 3 dans le sens horaire B. Les saillies 14 du ressort annulaire 15 entourant l'étoile 12 ont passé du vide 50 de l'étoile où elles se trouvaient précédemment sur les pointes 51 de ladite étoile et le palpeur 20 du râteau 21 a légèrement progressé le long de la rampe de la came 19. L'aiguille des heures 2 indique alors 1 heures 00 minute. A noter que la première roue 7 du mécanisme 3 est restée immobile, retenue qu'elle est par le rouage de la pièce d'horlogerie.The figures 7 and 9 show the same mechanism with a push button 5 depressed two-thirds of its total stroke. The wheel 24 has begun to turn counterclockwise A driven in rotation by the action of the toothing 27 of the rake 28 on the pinion 26 of said wheel 24 (see FIG. figure 9 ). The rotation of the wheel 24 has rotated the second wheel 8 of the mechanism 3 in the clockwise direction B. The projections 14 of the annular spring 15 surrounding the star 12 have passed a vacuum 50 of the star where they were previously on the tips 51 of said star and the probe 20 of the rake 21 has progressed slightly along the ramp of the cam 19. The hour hand 2 then indicates 1 hour 00 minutes. Note that the first wheel 7 of the mechanism 3 remained motionless, held that it is by the wheel of the timepiece.

La figure 8 montre le même mécanisme avec un bouton poussoir pressé à fond. La roue baladeuse 24 a continué à tourner dans le même sens antihoraire entraînant la seconde roue 8 du mécanisme 3 dans le même sens horaire. On comprendra alors que les saillies 14 du ressort annulaire 15 auront passé des pointes 51 de l'étoile 12 où elles se trouvaient précédemment sur les vides 52 de ladite étoile (voir figures 8 et 9). Le palpeur 20 du râteau 21 a encore progressé le long de la rampe de la came 19. L'aiguille des heures 2 indique alors 1 heures 30 minutes et le passage d'une heure à l'heure suivante a été effectué en conservant la fraction de 30 minutes affectée à l'heure de départ.The figure 8 shows the same mechanism with a push button pressed all the way. The wheel 24 continues to rotate in the same counterclockwise direction driving the second wheel 8 of the mechanism 3 in the same clockwise direction. It will be understood that the projections 14 of the annular spring 15 have passed points 51 of the star 12 where they were previously on the voids 52 of said star (see figures 8 and 9 ). The probe 20 of the rake 21 has progressed further along the ramp of the cam 19. The hour hand 2 then indicates 1 hour 30 minutes and the passage from one hour to the next hour has been carried out while keeping the fraction 30 minutes assigned to the departure time.

Une fois l'avance terminée de l'indicateur 2, on relâche la pression sur le bouton poussoir 5 et le râteau 28 revient à la place qu'il occupait rappelé par le ressort 46. Ce retour entraîne la roue baladeuse 24 à sa position de départ qui est sa position de repos.Once the advance of indicator 2 has been completed, the pressure on pushbutton 5 is released and rake 28 returns to the place it occupied, recalled by the spring 46. This return causes the wheel 24 to its starting position which is its rest position.
