Abstract

The invention relates to a device for adjusting a time indicator comprising a gear train (1), the kinematic chain of which comprises a sliding pinion (2) which is driven by a driving mobile (3). The sliding pinion drives a driven mobile (4) when the driving mobile turns in a first direction (A) and disconnects from said driven mobile when the driving mobile (9) turns in a second opposing direciton (B). The shaft (6) that forms the sliding pinion (2) is engaged in a groove (7) having first (9) and second (12) end sections, of which at least the first end section (9) is directed radially (R) to the driven mobile (4).

Description

La présente invention est relative à un dispositif de réglage d'un indicateur horaire comportant un train d'engrenage dont la chaîne cinématique comprend un pignon baladeur entraîné par un mobile menant ce pignon baladeur entraînant un mobile mené quand le mobile menant tourne dans un premier sens et se déconnectant dudit mobile mené quand ledit mobile menant tourne dans un second sens, opposé au premier, pour interrompre ladite chaîne cinématique.The present invention relates to a device for adjusting a time indicator comprising a gear train whose kinematic chain comprises a sliding pinion driven by a mobile driving the sliding pinion driving a driven mobile when the moving head rotates in a first direction and disconnecting said driven mobile when said mobile driving rotates in a second direction, opposite to the first, to interrupt said drive train.

Un tel dispositif est connu. Il équipe par exemple une montre affichant à la fois le quantième et le jour de la semaine telle que décrite dans le document FR-A-2 283 477 . Dans cette montre, la mise à la date et au jour de la semaine s'effectue au moyen d'une tige coiffée d'une couronne. Quand on tire la tige dans une première position et qu'on tourne la couronne dans un premier sens, on corrige la date. A partir de la même position tirée, on corrige le jour de la semaine en tournant la couronne dans un second sens, opposé au premier. Ces fonctions sont obtenues au moyen d'un pignon baladeur engrenant sur la tige et entraînant soit l'anneau de quantième, soit le disque des jours suivant le sens de rotation de la couronne.Such a device is known. It equips for example a watch displaying both the date and the day of the week as described in the document FR-A-2,283,477 . In this watch, setting the date and the day of the week is done by means of a stem topped with a crown. When we pull the rod in a first position and turn the crown in a first direction, we correct the date. From the same drawn position, we correct the day of the week by turning the crown in a second direction, opposite to the first. These functions are obtained by means of a sliding pinion meshing on the rod and driving either the date ring or the disc of the days following the direction of rotation of the crown.

Si le dispositif décrit ci-dessus donne entière satisfaction pour les fonctions évoquées, il présente un inconvénient majeur s'il s'agit de la mettre en oeuvre dans une montre comportant par exemple un quantième et un temporisateur, ce dernier permettant le comptage à rebours et l'affichage sur un cadran d'un intervalle de temps prédéterminé. En effet, en passant de la mise à la date du quantième à la mise au temps souhaité du temporisateur, ou vice-versa, on dérange ou dérègle le temps affiché par le temporisateur, ce dérangement étant provoqué par le pignon baladeur qui n'est pas introduit ou retiré du mobile qu'il entraîne selon une direction appropriée.If the device described above gives complete satisfaction for the functions mentioned, it has a major drawback if it is to implement it in a watch comprising for example a calendar and a timer, the latter allowing the countdown and displaying on a dial by a predetermined time interval. Indeed, by switching from the date date setting to the desired time setting of the timer, or vice versa, it disturbs or disrupts the time displayed by the timer, this derangement being caused by the sliding pinion which is not not introduced or removed from the mobile it drives in a proper direction.

Pour pallier cet inconvénient, le dispositif de l'invention, en plus qu'il satisfait à ce qui est décrit au premier paragraphe ci-dessus, est original et remarquable en ce que l'arbre que comporte le pignon baladeur est engagé dans une rainure présentant des première et seconde portions finales, au moins la première portion finale de cette rainure étant dirigée radialement au mobile mené par le pignon baladeur.To overcome this drawback, the device of the invention, in addition to that which is described in the first paragraph above, is original and remarkable in that the shaft that includes the sliding pinion is engaged in a groove having first and second end portions, at least the first end portion of this groove being directed radially to the mobile driven by the sliding pinion.

L'invention va être expliquée maintenant en détail ci-dessous par un mode d'exécution donné en exemple, cette exécution étant illustrée par les dessins annexés parmi lesquels :

  • la figure 1 est une vue en plan de la pièce d'horlogerie contenant l'invention;
  • la figure 2 est une vue en plan du dispositif de réglage selon l'invention, ce dispositif montrant un pignon baladeur en prise dans une chaîne cinématique;
  • la figure 3 est une vue en plan du dispositif de réglage selon l'invention, ce dispositif montrant un pignon baladeur déconnecté d'une chaîne cinématique;
  • la figure 4 est un agrandissement de la figure 2 dans lequel n'ont été conservés que les éléments propres à bien comprendre l'invention, et
  • la figure 5 est une coupe du dispositif de réglage selon l'invention.
The invention will now be explained in detail below by an exemplary embodiment, this embodiment being illustrated by the appended drawings in which:
  • the figure 1 is a plan view of the timepiece containing the invention;
  • the figure 2 is a plan view of the adjusting device according to the invention, this device showing a sliding pinion engaged in a kinematic chain;
  • the figure 3 is a plan view of the adjusting device according to the invention, this device showing a sliding pinion disconnected from a kinematic chain;
  • the figure 4 is an enlargement of the figure 2 in which only the elements of the invention have been properly understood, and
  • the figure 5 is a section of the adjusting device according to the invention.

La figure 1 est une vue en plan de la pièce d'horlogerie 10 contenant l'invention. Cette pièce comporte des aiguilles de garde-temps, soit une aiguille d'heure 30, une aiguille de minute 31 et une aiguille de petite seconde 32. Un calendrier à grand guichet 33 complète le garde-temps. La pièce d'horlogerie prise ici en exemple comporte encore une fonction chronographe avec une aiguille de seconde 34 et un compteur de minute 11. La mise en marche puis l'arrêt de l'aiguille 34 et du compteur 11 sont réalisés au moyen d'un premier poussoir 35, tandis qu'un deuxième poussoir 36 permet la mise à zéro des indicateurs 34 et 11. Une couronne 37 permet, suivant des positions axiales auxquelles elle est amenée, de remonter la pièce d'horlogerie, de mettre le calendrier au jour et de mettre à l'heure les aiguilles du garde-temps.The figure 1 is a plan view of the timepiece containing the invention. This piece includes timepiece needles, a 30-hour hand, a minute hand 31 and a small seconds hand 32. A calendar with a large counter 33 completes the timepiece. The timepiece taken here as an example still has a chronograph function with a second hand 34 and a minute counter 11. The starting and stopping of the needle 34 and the counter 11 are carried out by means of a first pusher 35, while a second pusher 36 allows the indicators 34 and 11 to be set to zero. A ring 37 makes it possible, according to the axial positions to which it is brought, to wind the timepiece, to set the calendar to day and set the timekeepers on time.

Dans la pièce d'horlogerie prise en exemple, le compteur de minute 11 est également utilisé comme temporisateur ou compteur à rebours 11, la mise au temps de la période à décompter étant confiée à la couronne 37. Le démarrage du temporisateur et le remontage d'un barillet de sonnerie actionnant une sonnerie indiquant la fin du comptage à rebours sont effectués en pressant sur un troisième poussoir 38. Comme le montrent toutes les figures annexées, le compteur-temporisateur 11 comporte un cadran 13 contenant trois échelles concentriques de dix minutes chacune et parcourues chacune par une aiguille de largeur différente 19, 20 et 21.In the timepiece taken as an example, the minute counter 11 is also used as a timer or countdown timer 11, the setting time of the period to be counted being entrusted to the crown 37. The start of the timer and the reassembly of the timer a ringing cylinder actuating a buzzer indicating the end of the countdown are performed by pressing a third pushbutton 38. As shown in all the accompanying figures, the counter-timer 11 comprises a dial 13 containing three concentric scales of ten minutes each and each traversed by a needle of different widths 19, 20 and 21.

Comme le montrent les figures 2 à 5, le dispositif de réglage d'un indicateur horaire - ici le temporisateur 11 - comporte un train d'engrenages 1 dont la chaîne cinématique comprend un pignon baladeur 2 entraîné par un mobile menant 3. Le pignon baladeur entraîne un mobile mené 4 quand le mobile menant 3 tourne dans un premier sens A. Cette situation est montrée en figure 2. A l'inverse, la figure 3 montre que lorsque le mobile menant 3 tourne dans un second sens B, opposé au premier, le pignon baladeur 2 se déconnecte du mobile mené 4. La chaîne cinématique est alors interrompue.As shown by Figures 2 to 5 , the device for adjusting a time indicator - here the timer 11 - comprises a gear train 1 whose kinematic chain comprises a sliding pinion 2 driven by a driving mobile 3. The sliding pinion drives a driven mobile 4 when the mobile leading 3 turns in a first sense A. This situation is shown in figure 2 . Conversely, the figure 3 shows that when the driving mobile 3 rotates in a second direction B, opposite to the first, the sliding pinion 2 disconnects the driven mobile 4. The kinematic chain is then interrupted.

Pour bien comprendre l'invention on se reportera maintenant à la figure 4. On voit bien ici que le pignon baladeur 2 comporte un arbre 6 engagé dans une rainure 7 pratiquée par exemple dans la platine ou dans un pont de la pièce d'horlogerie. Cette rainure 7 présente des première et seconde portions finales 9 et 12, l'invention résidant dans le fait qu'au moins la première portion finale 9 de la rainure 7 est dirigée radialement (référence R) au mobile mené 4.To understand the invention, we will now refer to the figure 4 . It is clear here that the sliding pinion 2 comprises a shaft 6 engaged in a groove 7 made for example in the plate or in a bridge of the timepiece. This groove 7 has first and second end portions 9 and 12, the invention residing in the fact that at least the first end portion 9 of the groove 7 is directed radially (reference R) to the driven mobile 4.

La figure 4 fait bien comprendre que lorsque le pignon baladeur 2 s'engage ou se désengage du mobile mené 4, il est contraint de suivre la première portion 9 de la rainure 7, cette portion étant dirigée vers le centre du mobile mené 4. Ainsi, en quittant la denture 14 du mobile mené 4, le pignon baladeur 2 ne change en rien la position angulaire dudit mobile mené et donc ne perturbe en rien la valeur de temps introduite dans le temporisateur 11 qui se trouve en fin de la chaîne cinématique.The figure 4 makes it clear that when the sliding pinion 2 engages or disengages the driven mobile 4, it is forced to follow the first portion 9 of the groove 7, this portion being directed towards the center of the driven mobile 4. Thus, leaving the toothing 14 of the driven mobile 4, the sliding pinion 2 in no way changes the angular position of said driven mobile and therefore does not disturb the value of time introduced into the timer 11 which is at the end of the kinematic chain.

L'examen de la figure 4 fera comprendre aussi que la largeur de la première portion finale 9 de la rainure 7 ou, en d'autres termes, la longueur L du chemin parcouru par l'arbre 6 du baladeur 2 dans ladite première portion finale 9 doit être sensiblement supérieure à la hauteur h des dents 14 du mobile mené 4, ceci pour permettre au pignon baladeur de se dégager complètement dudit mobile mené.The examination of figure 4 will also understand that the width of the first final portion 9 of the groove 7 or, in other words, the length L of the path traveled by the shaft 6 of the player 2 in said first final portion 9 must be substantially greater than the height h of the teeth 14 of the driven mobile 4, this to allow the sliding pinion to completely disengage said driven mobile.

On a déjà mentionné plus haut que l'indicateur horaire considéré ici est un temporisateur 11 permettant le comptage à rebours et l'affichage sur un cadran 13 d'un intervalle de temps prédéterminé. Les figures montrent que le dispositif de réglage de ce temporisateur comprend une tige 15 coiffée par une couronne 37 pouvant être actionnée manuellement, un ensemble formé d'un pignon coulant 16, d'une tirette 7 et d'une bascule 18 liés à la tige 15, et un train d'engrenages 1 aboutissant audit temporisateur constitué de la roue des minutes 8. Le train d'engrenages 1 est susceptible d'être entraîné par le pignon coulant 16 lorsque la tige 15 se trouve tirée dans une position axiale déterminée (dans cet exemple : première position tirée).It has already been mentioned above that the time indicator considered here is a timer 11 allowing the countdown and the display on a dial 13 of a predetermined time interval. The figures show that the adjustment device of this timer comprises a rod 15 capped by a ring 37 that can be manually actuated, a set formed by a sliding pinion 16, a pull tab 7 and a rocker 18 connected to the rod 15, and a gear train 1 leading to said timer consisting of the minute wheel 8. The gear train 1 is capable of being driven by the sliding pinion 16 when the rod 15 is pulled into a predetermined axial position ( in this example: first drawn position).

Les figures 2 et 3 montrent le mécanisme lié à la tige 15. On y trouve de façon classique la tirette 17 qui pivote en 40. La première extrémité de la tirette est engagée par un pion 42 dans une rainure 41 de la tige 15. La seconde extrémité de la tirette commande la bascule 18, elle-même engagée dans une rainure 43 du pignon coulant 16. La position de la tirette 17 est assurée par un ressort-sautoir 44. Le mécanisme est complété par une seconde bascule 45 qui est commandée par la tirette 17 et pivote en 46, cette seconde bascule 46 portant le mobile menant 3.The figures 2 and 3 show the mechanism associated with the rod 15. There is conventionally the pull tab 17 which pivots at 40. The first end of the pull tab is engaged by a pin 42 in a groove 41 of the rod 15. The second end of the zipper control lever 18, itself engaged in a groove 43 of the sliding pinion 16. The position of the pull tab 17 is provided by a jumper spring 44. The mechanism is completed by a second latch 45 which is controlled by the pull tab 17 and pivots at 46, this second rocker 46 carrying the moving head 3.

Les mêmes figures 2 et 3 ainsi que la coupe de la figure 5 montrent de quels éléments est composé le train d'engrenages 1. Le pignon coulant 16 entraîne le pignon menant 3 qui entraîne à son tour le pignon baladeur 2. Lorsque la tige tourne dans le sens E (voir figure 2), le pignon baladeur 2 entraîne le mobile mené 4 qui est composé, comme on le voit sur la figure 5, de deux roues 47 et 48 montées coaxialement et solidaires l'une de l'autre. La roue 48 engrène une roue 49 montée solidaire et coaxiale à une roue 50 qui entraîne finalement la roue des minutes 8 qui constitue le temporisateur 11.The same figures 2 and 3 as well as the cut of the figure 5 show which elements is composed of the gear train 1. The sliding gear 16 drives the driving gear 3 which in turn drives the sliding gear 2. When the rod rotates in the direction E (see figure 2 ), the sliding pinion 2 drives the driven mobile 4 which is composed, as seen on the figure 5 two wheels 47 and 48 mounted coaxially and secured to one another. The wheel 48 meshes with a wheel 49 mounted integral and coaxial with a wheel 50 which ultimately causes the minute wheel 8 which constitutes the timer 11.

On a vu ci-dessus que le mobile mené 4 comprend une roue 47 engrenant avec le pignon baladeur 2 (voir particulièrement la figure 4). Dans la pièce d'horlogerie prise ici en exemple, on voit que deux dents 14 de la roue 47 sont embrassées par un seul espace entre-dent du pignon baladeur 2 et que les dents 14 de la roue 47 ont un profil particulier. Cet arrangement permet une introduction en douceur du pignon baladeur 2 dans la roue 47. On comprendra aussi que ce profil particulier évite l'arqueboutement des dents 14 sur la denture du pignon baladeur 2 quand ce dernier pénètre dans la roue 47.We have seen above that the driven mobile 4 comprises a wheel 47 meshing with the sliding pinion 2 (see particularly the figure 4 ). In the timepiece taken here as an example, it can be seen that two teeth 14 of the wheel 47 are embraced by a single inter-tooth space of the sliding pinion 2 and that the teeth 14 of the wheel 47 have a particular profile. This arrangement allows a smooth introduction of the sliding pinion 2 in the wheel 47. It will also be understood that this particular profile avoids the arqueboutement of the teeth 14 on the toothing of the sliding pinion 2 when the latter enters the wheel 47.

La description du dispositif de réglage donnée plus haut permet maintenant d'expliquer le fonctionnement dudit dispositif.The description of the adjustment device given above now makes it possible to explain the operation of said device.

Lorsque la tige 15 est tirée dans une position axiale déterminée (il s'agit ici de la première position tirée) et que la couronne 37 est tournée dans un premier sens (soit le sens E ou sens horaire comme le montre la figure 2), le pignon baladeur 2 vient en prise avec le mobile mené 4 et plus précisément la roue 47 de ce mobile 4. L'arbre 6 du pignon baladeur 2 se positionne alors au fond de la première portion 9 de la rainure 7 dans laquelle il s'est déplacé. A partir de ce moment, et si on continue à tourner la couronne 37 dans le même sens E, on entraîne la roue des minutes 8 du temporisateur 11 dans le sens de la flèche M ce qui permet de choisir l'intervalle de temps désiré. Une fois cet intervalle de temps choisi, on presse sur le poussoir 38 (voir figure 1) pour armer simultanément un barillet qui fera retentir une sonnerie à la fin du comptage à rebours.When the rod 15 is pulled in a determined axial position (this is the first drawn position) and the ring 37 is rotated in a first direction (E or direction clockwise as shown in FIG. figure 2 ), the sliding pinion 2 engages the driven mobile 4 and more precisely the wheel 47 of the mobile 4. The shaft 6 of the sliding pinion 2 is then positioned at the bottom of the first portion 9 of the groove 7 in which it moved. From this moment, and if we continue to turn the crown 37 in the same direction E, it drives the minute wheel 8 of the timer 11 in the direction of the arrow M which allows to choose the desired time interval. Once this time interval has been chosen, the pusher 38 is pressed (see FIG. figure 1 ) to simultaneously arm a barrel that will sound a bell at the end of the countdown.

On remarquera ici que le mécanisme montré à la figure 2 est vu sous la pièce d'horlogerie, ce qui explique que la direction de la flèche M se trouve être l'inverse du sens de décomptage montré en figure 1 où la pièce d'horlogerie est vue de dessus.It will be noted here that the mechanism shown in figure 2 is seen under the timepiece, which explains why the direction of the arrow M is the reverse of the counting direction shown in figure 1 where the timepiece is seen from above.

Lorsque la tige 15 est tirée dans la même position axiale que celle établie ci-dessus et que la couronne 37 est tournée dans un second sens (soit le sens F ou sens antihoraire comme le montre la figure 3), le pignon baladeur 2 se déconnecte du mobile mené 4 et plus précisément de la roue 47 de ce mobile 4. L'arbre 6 du pignon baladeur 2 se positionne alors au fond de la seconde portion 12 de la rainure 7 dans laquelle il s'est déplacé. A partir de ce moment et si on continue à tourner la couronne 37 dans le même sens F, on entraîne le pignon baladeur 2 dans le sens de la flèche N ce qui permet la mise à la date d'un quantième 33 (voir figure 1). A cet effet, le pignon baladeur 2 porte une étoile (voir aussi figure 5). Cette étoile est en prise avec un mécanisme de calendrier (non représenté ici).When the rod 15 is pulled in the same axial position as that established above and the ring 37 is rotated in a second direction (either the direction F or counterclockwise direction as shown in FIG. figure 3 ), the sliding pinion 2 disconnects the driven mobile 4 and more precisely the wheel 47 of the mobile 4. The shaft 6 of the sliding pinion 2 is then positioned at the bottom of the second portion 12 of the groove 7 in which it s is moved. From this moment and if we continue to turn the crown 37 in the same direction F, we drive the sliding pinion 2 in the direction of the arrow N which allows the setting on the date of a date 33 (see figure 1 ). For this purpose, the sliding pinion 2 carries a star (see also figure 5 ). This star is engaged with a calendar mechanism (not shown here).

Les figures 2, 3 et 4 montrent que la bascule 18 porte ou est prolongée par un crochet 22. Ce crochet est susceptible d'entraîner rapidement l'arbre 6 du pignon baladeur 2 au fond de la seconde portion finale 12 de la rainure 7. En effet, quand la tige 15 se trouve poussée dans une position permettant le remontage de la pièce d'horlogerie, le pignon coulant 16 se déplace dans le sens de la flèche G montrée en figure 4, ce qui entraîne la bascule 18 et le crochet 22 dans la même direction. Le crochet 22 vient en appui sur l'arbre 6 et entraîne rapidement cet arbre et le baladeur 2 qui lui est lié d'abord le long de la première portion 9 puis de la seconde portion 12 de la rainure 7. Le pignon baladeur 2 est ainsi dégagé rapidement de la roue menée 47 ce qui évite ainsi tout déréglage sur la chaîne du temporisateur, ce déréglage pouvant intervenir du fait que le baladeur est laissé libre.The figures 2 , 3 and 4 show that the rocker 18 carries or is extended by a hook 22. This hook is able to quickly drive the shaft 6 of the sliding pinion 2 at the bottom of the second final portion 12 of the groove 7. Indeed, when the rod 15 is pushed into a position for reassembly of the timepiece, the sliding pinion 16 moves in the direction of the arrow G shown in FIG. figure 4 which causes the rocker 18 and the hook 22 in the same direction. The hook 22 comes to bear on the shaft 6 and quickly drives this shaft and the player 2 which is connected first along the first portion 9 and the second portion 12 of the groove 7. The sliding pinion 2 is thus quickly clear of the driven wheel 47 which thus avoids any maladjustment on the timer chain, this maladjustment may occur because the player is left free.
