Description

MECANISME DE SELECTION ET D'ACTION NEMENT DE FONCTIONS D'UN  MECHANISM FOR SELECTING AND ACTING FUNCTIONS OF A
MOUVEMENT HORLOGER  WATCHMAKING MOVEMENT
La présente invention se rapporte au domaine de l'horlogerie et concerne plus particulièrement un mécanisme de sélection et d'actionnement de fonctions d'un mouvement horloger. The present invention relates to the field of watchmaking and more particularly relates to a mechanism for selecting and operating functions of a watch movement.
Une pièce d'horlogerie est généralement dotée de plusieurs fonctions. Par exemple, une fonction commune à toutes les pièces d'horlogerie est la mise à l'heure permettant de régler l'affichage du temps courant. Une autre fonction commune à toutes les montres mécaniques est le remontage de la source d'énergie. Si la pièce d'horlogerie permet d'afficher d'autres indications horaires que le temps courant, elle doit comporter également des fonctions de correction des différents affichages. A timepiece is generally equipped with several functions. For example, a function common to all timepieces is the setting time to adjust the display of the current time. Another function common to all mechanical watches is the reassembly of the energy source. If the timepiece makes it possible to display other time indications than the current time, it must also include correction functions for the different displays.
Un autre mécanisme de sélection et de correction est décrit dans le brevet EP2214066 et s'applique à une pièce d'horlogerie munie d'un premier et d'un deuxième organes d'indication de temps. Ce mécanisme de correction comprend une tige de remontoir, un mobile correcteur monté baladeur entre une première et une deuxième positions de correction dans lesquelles le mobile est en lien cinématique respectivement avec le premier et le deuxième organes d'indication de temps. Le mécanisme comprend des moyens pour entraîner le mobile correcteur à l'aide de la tige de remontoir, et un mécanisme de sélection de la position de correction comprenant un bras sélecteur coopérant avec le mobile correcteur pour l'entraîner de la première position de correction à la deuxième position de correction, un organe de positionnement angulaire du bras sélecteur et un organe de commande dudit organe de positionnement angulaire. Toutefois, ce mécanisme, du fait de sa construction, est limité à la correction de deux fonctions uniquement. CH702548 décrit un mécanisme de sélection susceptible d'être en position neutre ou de se déplacer entre deux positions de correction par pression sur la couronne de remontoir, la correction se faisant uniquement par rotation de la couronne de remontoir, sans avoir à tirer sur la tige de remontoir. Pour cela, le mécanisme comprend une bascule présentant deux bras sur chacun desquels est monté un mobile de correction. La bascule pivote pour sélectionner et actionner l'une ou l'autre des deux fonctions à corriger au moyen de l'un des mobiles de correction mis en contact avec un organe de la fonction à corriger. Toutefois, si l'on ne prend pas en compte la position neutre dans laquelle la bascule est en position neutre, ce mécanisme, du fait de sa construction, est limité à la correction de deux fonctions uniquement, la bascule ne pouvant pivoter qu'entre deux positions. Another selection and correction mechanism is described in EP2214066 and applies to a timepiece provided with first and second time indicating members. This correction mechanism comprises a winding stem, a corrective mobile mounted walker between a first and a second correction positions in which the mobile is in kinematic connection respectively with the first and second time indicating members. The mechanism comprises means for driving the corrective mobile with the winding stem, and a correction position selection mechanism comprising a selector arm cooperating with the corrective mobile to drive it from the first correction position to the second correction position, an angular positioning member of the selector arm and a control member of said angular positioning member. However, this mechanism, because of its construction, is limited to the correction of two functions only. CH702548 describes a selection mechanism that can be in the neutral position or move between two pressure correction positions on the winding crown, the correction being made only by rotation of the winding crown, without having to pull the rod winding. For this, the mechanism comprises a rocker having two arms on each of which is mounted a correction mobile. The flip-flop pivots to select and actuate one or the other of the two functions to be corrected by means of one of the correction mobiles. put in contact with an organ of the function to be corrected. However, if one does not take into account the neutral position in which the rocker is in the neutral position, this mechanism, because of its construction, is limited to the correction of only two functions, the rocker being able to rotate only between two positions.
On connaît également CH702803 qui décrit un mécanisme de correction comprenant des leviers de correction agencés pour incrémenter des organes de comptage, un levier de commande monté pivotant selon un premier axe de rotation et un bras monté pivotant sur ledit levier de commande selon un deuxième axe de rotation. Le bras se déplace angulairement par rapport au levier de commande en réponse à une rotation de la couronne pour se placer en regard de l'un ou l'autre des leviers de correction. Le levier de commande pivote pour actionner le levier de correction sélectionné en réponse à une action sur un poussoir. La correction ne peut donc se faire que par incrémentation des différents organes de comptage, ce qui rend impossible un fonctionnement bidirectionnel. Seule une correction unidirectionnelle des organes de comptage est possible. Also known is CH702803 which describes a correction mechanism comprising correction levers arranged to increment counting members, a control lever pivotally mounted along a first axis of rotation and an arm pivotally mounted on said control lever along a second axis of rotation. rotation. The arm moves angularly relative to the control lever in response to a rotation of the crown to be placed opposite one or the other of the correction levers. The control lever pivots to actuate the selected correction lever in response to an action on a pusher. Correction can only be done by incrementing the different counting devices, which makes bidirectional operation impossible. Only unidirectional correction of counting devices is possible.
Le but de la présente invention est de pallier ces inconvénients, en proposant un mécanisme de sélection et d'actionnement de n fonctions d'un mouvement horloger permettant de sélectionner et d'actionner plus de deux fonctions différentes d'un mouvement horloger. The object of the present invention is to overcome these disadvantages, by providing a mechanism for selecting and operating n functions of a watch movement for selecting and operating more than two different functions of a watch movement.
Conformément à l'invention, un mécanisme de sélection et d'actionnement de fonctions d'un mouvement horloger comprend une tige de remontoir terminée à une de ses extrémités par une couronne. La tige de remontoir est déplaçable en rotation et en translation axiale et est agencée pour occuper trois positions axiales distinctes : - Une première position de remontage, According to the invention, a mechanism for selecting and operating functions of a watch movement comprises a winding stem terminated at one of its ends by a crown. The winding stem is movable in rotation and in axial translation and is arranged to occupy three distinct axial positions: a first winding position,
- Une deuxième position de sélection d'une parmi un nombre n de fonctions en réponse à une rotation de la tige de remontoir autour de son axe, et A second position for selecting one of a number n of functions in response to a rotation of the winding stem about its axis, and
- Une troisième position d'actionnement d'une fonction liée cinématiquement à la couronne de remontoir. Le mécanisme comprend en outre une roue à came qui, lorsque le mécanisme de sélection est dans sa deuxième position, est reliée cinématiquement à la tige de remontoir, ladite roue à came comportant un élément de guidage sur lequel sont agencées n positions de repos correspondant chacune à une fonction. Dans une forme d'exécution, le mécanisme comporte un dispositif d'embrayage comportant des roues dentées, le dispositif d'embrayage mettant temporairement en prise avec des rouages du mouvement horloger pour actionner une parmi n fonctions. Selon cette forme d'exécution, le dispositif d'embrayage comporte une plaque de forme allongée comportant des trous aptes à recevoir des pignons, pivotant autour d'un des axes desdits trous pour actionner une parmi n fonctions. - A third actuating position of a function kinematically linked to the winding crown. The mechanism further comprises a cam wheel which, when the selection mechanism is in its second position, is kinematically connected to the winding stem, said cam wheel having a guide element on which are arranged n rest positions corresponding to each to a function. In one embodiment, the mechanism includes a clutch device having gear wheels, the clutch device temporarily engaging the workings of the watch movement to actuate one of n functions. According to this embodiment, the clutch device comprises an elongated plate having holes adapted to receive gears, pivoting about one of the axes of said holes to actuate one of n functions.
Dans une forme d'exécution préférentielle, l'élément de guidage est une rainure agencée dans la roue à came, la rainure étant par exemple sous la forme d'une ligne courbe, notamment une ligne courbe ouverte à deux extrémités. Selon cette forme d'exécution préférentielle, un tenon s'engage dans la rainure agencée dans la roue à came, autour duquel un pignon peut tourner librement, le tenon étant solidaire de la plaque de forme allongée. In a preferred embodiment, the guide element is a groove arranged in the cam wheel, the groove being for example in the form of a curved line, in particular a curved line open at two ends. According to this preferred embodiment, a tenon engages in the groove arranged in the cam wheel, around which a pinion can rotate freely, the pin being integral with the elongated plate.
Dans une forme d'exécution, le mécanisme comporte parmi les n fonctions, une fonction de mise à l'heure, une fonction de correction du quantième et une fonction d'affichage d'au moins un second fuseau horaire. Normalement le nombre n de fonctions serait de trois ou quatre mais pour des raisons pratiques, le nombre n ne va pas normalement dépasser cinq. In one embodiment, the mechanism comprises among the n functions, a time setting function, a date correction function and a display function of at least a second time zone. Normally the number n of functions would be three or four but for practical reasons the number n will not normally exceed five.

- La figure 14 représente une montre-bracelet comportant un mécanisme selon la présente invention. Comme illustré à la figure 1 , une montre comporte un mécanisme de sélection et d'actionnement de quatre fonctions d'un mouvement horloger comprenant une tige de remontoir 1 terminée à son extrémité externe par une couronne (non représentée). La tige de remontoir 1 est déplaçable en rotation et en translation axiale. La tige de remontoir est agencée pour occuper trois positions axiales distinctes : - Figure 14 shows a wristwatch with a mechanism according to the present invention. As illustrated in FIG. 1, a watch comprises a mechanism for selecting and operating four functions of a watch movement comprising a winding stem 1 terminated at its outer end by a crown (not shown). The winding stem 1 is movable in rotation and in axial translation. The winding stem is arranged to occupy three distinct axial positions:
- Une première position de remontage (figure 1 ), - A first winding position (Figure 1),
- Une deuxième position de sélection d'une parmi trois fonctions en réponse à une rotation de la tige de remontoir 1 autour de son axe (figure 2A, figure 4 et figure 1 1 ), et - Une troisième position d'actionnement d'une fonction (figure 3 et figure 13) liée cinématiquement à la couronne de remontoir, A second position for selecting one of three functions in response to a rotation of the winding stem 1 about its axis (FIG. 2A, FIG. 4 and FIG. 11); and a third actuating position of a function (FIG. 3 and FIG. 13) kinematically linked to the winding crown,
Le mécanisme, comprend en outre une roue à came 7 (voir aussi figures 6a et 6B) qui, lorsque la tige de remontoir est dans sa deuxième position, est reliée cinématiquement à la tige de remontoir 1 . La roue à came 7 comporte un élément de guidage 8 sur lequel sont agencées trois positions de repos correspondant chacune à une fonction. The mechanism further comprises a cam wheel 7 (see also FIGS. 6a and 6b) which, when the winding stem is in its second position, is connected kinematically to the winding stem 1. The cam wheel 7 comprises a guide element 8 on which are arranged three rest positions each corresponding to a function.
Ainsi, dans cet exemple, les trois fonctions disponibles lorsque le mécanisme de sélection est dans sa deuxième position ajoutées à la fonction de remontage de la montre lorsque la tige de remontoir est dans sa première position permettent donc d'offrir quatre fonctions différentes. Thus, in this example, the three functions available when the selection mechanism is in its second position added to the winding function of the watch when the winding stem is in its first position thus allow to offer four different functions.
Dans l'exemple illustré à la figure 1 , la tige de remontoir 1 est dans sa première position. Dans cette configuration, en faisant tourner la tige de remontoir 1 , un pignon coulant 3, solidaire de la tige de remontoir, tourne en entraînant le pignon de remontoir 2. In the example illustrated in Figure 1, the winding stem 1 is in its first position. In this configuration, by rotating the winding stem 1, a sliding pinion 3, integral with the winding stem, rotates by driving the winding pinion 2.
Dans l'exemple illustré à la figure 2A, la tige de remontoir 1 est dans sa deuxième position. C'est dans cette deuxième position que s'effectue la sélection de la fonction. Un pignon coulant 3 s'engrène avec un renvoi 4. Le renvoi 4 entraîne la roue à came 7 au moyen de pignons doubles 5a, 5b, 6a, 6b. Dans cette configuration, la fonction sélectionnée correspond à la mise à l'heure dès lors que la tige de remontoir sera dans sa troisième position. Dans une deuxième position, le dispositif d'embrayage 9 est agencé de manière à ce qu'un pignon 13 du dispositif d'embrayage 9 s'engrène avec la roue des minutes 10. Comme illustré aux figures 2A et 2B, une goupille 57 de l'embrayage a poussé sur le plan d'impulsion X d'un baladeur 55, ledit baladeur 55 tournant alors dans le sens des aiguilles d'une montre autour de son axe Z (figure 2A et figure 10). Une surface Y (figure 2A et figure 10) du baladeur 55 a tendu un ressort de rappel 53 (figure 2A). Le baladeur n'est plus en contact avec sa butée W. Le pignon 13 de l'embrayage s'engrène toujours avec le pignon 54 du baladeur. Il n'y a pas de contact entre le pignon 54 du baladeur et le mobile de correction de la date 52a, 52b. Il n'y pas de contact entre le pignon 18a de l'embrayage et la roue GMT 1 1 . In the example illustrated in Figure 2A, the winding stem 1 is in its second position. It is in this second position that the selection of the function is made. A sliding pinion 3 meshes with a return 4. The return 4 drives the cam wheel 7 by means of double pinions 5a, 5b, 6a, 6b. In this configuration, the function selected corresponds to the time setting when the winding stem is in its third position. In a second position, the clutch device 9 is arranged in such a way that a pinion 13 of the clutch device 9 meshes with the minute wheel 10. As illustrated in FIGS. 2A and 2B, a pin 57 of the clutch has pushed on the pulse plane X of a player 55, said player 55 then rotating clockwise about its axis Z (Figure 2A and Figure 10). A surface Y (FIG. 2A and FIG. 10) of the slide 55 has stretched a return spring 53 (FIG. 2A). The player is no longer in contact with its stopper W. The pinion 13 of the clutch always meshes with the pinion 54 of the player. There is no contact between the pinion 54 of the player and the mobile date correction 52a, 52b. There is no contact between the gear 18a of the clutch and the wheel GMT 1 1.
Comme illustré à la figure 10, le baladeur 55, comporte un pignon 54, le pivot du pignon 54 tournant librement dans un trou du baladeur 55. Le baladeur 55 comporte un trou de pivotement Z du baladeur, une surface de contact Y sur laquelle agit un ressort de rappel faisant tourner le baladeur 55 dans le sens inverse des aiguilles d'une montre et un plan d'impulsion X pour faire tourner le baladeur dans le sens des aiguilles d'une montre. As shown in Figure 10, the player 55 comprises a pinion 54, the pinion of the pinion 54 freely rotating in a hole of the player 55. The player 55 comprises a pivoting hole Z of the player, a contact surface Y on which acts a return spring rotating the player 55 counterclockwise and a pulse plane X to rotate the player in the direction of clockwise.
Comme illustré à la figure 3, la tige de remontoir 1 est dans sa troisième position. Ainsi, en faisant tourner la tige de remontoir 1 , l'heure se règle grâce au pignon 13 du dispositif d'embrayage 9 qui s'engrène avec la roue des minutes 10, au moyen du renvoi 4 et des roues dentées 14, 15, 16. As illustrated in Figure 3, the winding stem 1 is in its third position. Thus, by rotating the winding stem 1, the time is adjusted by the pinion 13 of the clutch device 9 which meshes with the minute wheel 10, by means of the gear 4 and the toothed wheels 14, 15, 16.
Dans l'exemple illustré à la figure 4, la tige de remontoir 1 est dans la deuxième position. La rotation de la tige de remontoir 1 a permis de faire tourner la roue à came 7. Ainsi, le dispositif d'embrayage 9 a effectué une rotation autour de son pivot A. Le pignon 13 n'engrène plus avec la roue des minutes 10 mais c'est un pignon double 18a, 18b qui s'engrène avec la roue GMT 1 1 . Ainsi, dans cette configuration, dès lors que la tige de remontoir sera dans sa troisième position, un réglage de l'aiguille GMT sera possible. Le baladeur 55 se trouve dans sa position de repos. Il reste contre une butée W qui fait partie de la platine. Le ressort de rappel 53 maintien le baladeur 55 en contact avec la butée W. Il n'y a pas de contact entre le pignon 13 de l'embrayage et le pignon 54 du baladeur 55. In the example illustrated in Figure 4, the winding stem 1 is in the second position. The rotation of the winding stem 1 has made it possible to turn the cam wheel 7. Thus, the clutch device 9 has rotated about its pivot A. The pinion 13 no longer meshes with the minute wheel 10 but it is a double gear 18a, 18b which meshes with the GMT wheel 1 1. Thus, in this configuration, as soon as the winding stem is in its third position, a setting of the GMT hand will be possible. The player 55 is in its rest position. It remains against a stop W which is part of the platinum. The return spring 53 holds the slide 55 in contact with the stop W. There is no contact between the pinion 13 of the clutch and the pinion 54 of the player 55.
Selon cet exemple, pour actionner la correction d'une aiguille GMT, la tige de remontoir 1 doit être dans sa troisième position. Le pignon coulant 3 s'engrène alors avec le renvoi 4, mais maintenant le renvoi 4 s'engrène avec le pignon 16 de l'embrayage. En faisant tourner la tige remontoir 1 , on fait tourner tous les pignons 16, 17, 18a, 18b du dispositif d'embrayage. Ainsi, un réglage d'une aiguille GMT peut être effectué pour afficher un second fuseau horaire. According to this example, to actuate the correction of a GMT hand, the winding stem 1 must be in its third position. The sliding pinion 3 then meshes with the return 4, but now the return 4 meshes with the pinion 16 of the clutch. By turning the winding stem 1, all the gears 16, 17, 18a, 18b of the clutch device are rotated. Thus, a setting of a GMT hand can be performed to display a second time zone.
Le dispositif d'embrayage 9 comporte des roues dentées 13, 14, 15, 16, 17, 18a, 18b (figure 5). Le dispositif d'embrayage 9 met temporairement en prise des rouages du mouvement horloger pour actionner une parmi trois fonctions. Le dispositif d'embrayage 9 comporte une plaque de forme allongée 12 comportant des trous aptes à recevoir des pignons, en l'occurrence six trous ainsi qu'une goupille 57 agencée à une extrémité de la plaque allongée 12, ladite plaque allongée 12 pivotant autour d'un axe central A (figure 4) pour actionner une parmi les trois fonctions. Le dispositif d'embrayage 9 est donc muni de six pignons 13, 14, 15, 16, 17, 18a, 18b, qui pivotent librement sur les six trous de la plaque allongée 12. Des tenons (voir figure 5) sont chassés dans les trous, permettant aux six pignons 13, 14, 15, 16, 17, 18a, 18b de pivoter sur ces tenons. La roue à came 7 comporte une rainure 8 (figure 6A) de manière à ce qu'un tenon, non illustré, du pignon 13 dépasse en dessous de la plaque allongée 12 du dispositif d'embrayage pour s'engager dans la rainure 8 de la roue à came 7. La roue à came 7 comporte une rainure ouverte 8 à deux extrémités définissant chacune une position de repos PR1 , PR3. La rainure 8 a une forme coudée définissant une troisième position de repos PR2. Chacune des positions de repos PR1 , PR2, PR3 correspond à une fonction. La figure 6B illustre la face arrière de la roue à came 7 permettant alors de visualiser une roue 20, solidaire de la roue à came 7, agencée pour coopérer avec un sautoir 21 (figure 7) de manière à indexer les positions de la roue à came 7. The clutch device 9 comprises gear wheels 13, 14, 15, 16, 17, 18a, 18b (Figure 5). The clutch device 9 temporarily engages the workings of the watch movement to actuate one of three functions. The clutch device 9 comprises an elongated plate 12 having holes capable of receiving sprockets, in this case six holes and a pin 57 arranged at one end of the elongated plate 12, said elongated plate 12 pivoting around a central axis A (Figure 4) to operate one of the three functions. The clutch device 9 is thus provided with six pinions 13, 14, 15, 16, 17, 18a, 18b, which pivot freely on the six holes of the elongate plate 12. Studs (see FIG. holes, allowing the six pinions 13, 14, 15, 16, 17, 18a, 18b to pivot on these tenons. The cam wheel 7 has a groove 8 (FIG. 6A) so that a pin, not shown, of the pinion 13 protrudes below the elongated plate 12 of the clutch device to engage in the groove 8 of the the cam wheel 7. The cam wheel 7 has an open groove 8 with two ends each defining a rest position PR1, PR3. The groove 8 has a bent shape defining a third rest position PR2. Each of the rest positions PR1, PR2, PR3 corresponds to a function. FIG. 6B illustrates the rear face of the cam wheel 7, which then makes it possible to visualize a wheel 20, integral with the cam wheel 7, arranged to cooperate with a jumper 21 (FIG. 7) so as to index the positions of the wheel to cam 7.
Sur le même principe que précédemment, et comme illustré à la figure 1 1 , le dispositif d'embrayage permet de sélectionner une fonction pour le réglage du quantième. Dans cet exemple, un pignon 13 de l'embrayage s'engrène avec un pignon 54 du baladeur 55. Il n'y pas de contact entre le pignon 18a de l'embrayage et la roue GMT 1 1 . Il n'y a pas de contact entre le pignon 13 de l'embrayage et la roue des minutes 10. Le baladeur 55 se trouve toujours dans sa position de repos, et en contact avec sa butée W. Dans cette position, le pignon 54 du baladeur s'engrène avec le mobile de la correction de la date 52. La goupille 57 de l'embrayage est en contact avec le plan d'impulsion X du baladeur 55 (voir figure 12). Comme illustré à la figure 13, la tige de remontoir 1 se trouve dans sa troisième position, pour actionner la fonction de la correction du quantième. Le pignon coulant 3 entraîne le renvoi 4. Le renvoi 4 entraîne le pignon 16 et, par conséquent, tous les mobiles de l'embrayage 9. Le pignon 13 de l'embrayage entraîne le pignon 54 du baladeur. Le pignon 54 du baladeur entraine le mobile de correction de la date 52a, 52b (voir figure 9A et figure 9B) qui entraîne le disque de quantième 56. On the same principle as before, and as illustrated in Figure 1 1, the clutch device allows to select a function for setting the date. In this example, a pinion 13 of the clutch meshes with a pinion 54 of the player 55. There is no contact between the pinion 18a of the clutch and the wheel GMT January 1. There is no contact between the pinion 13 of the clutch and the minute wheel 10. The player 55 is still in its rest position, and in contact with its stop W. In this position, the pinion 54 of the player meshes with the mobile of the correction of the date 52. The pin 57 of the clutch is in contact with the pulse plane X of the player 55 (see Figure 12). As illustrated in Figure 13, the winding stem 1 is in its third position, to actuate the function of the date correction. The sliding pinion 3 causes the return 4. The return 4 drives the pinion 16 and, therefore, all the movable clutch 9. The pinion 13 of the clutch drives the pinion 54 of the player. The pinion 54 of the player drives the date correction mobile 52a, 52b (see FIG. 9A and FIG. 9B) which drives the date disc 56.
Des repères sur la tige de remontoir 1 , sur la couronne et/ou sur un boîtier permettent de visualiser facilement la position relative de la couronne et de la tige de remontoir 1 par rapport au boîtier. Ces repères peuvent être réalisés sur une ou sur les deux pièces, par un marquage ou par l'usinage d'une gorge ou d'une rainure. Il est également possible de déterminer la fonction sélectionnée en affichant sur un cadran de montre la fonction sélectionnée, comme cela est illustré à la figure 14 grâce à une aiguille 19 visible depuis une glace de montre. La roue à came 7 entraîne un double-pignon 50, qui entraîne un secteur 51 (voir figure 8). L'axe de pivotement du secteur est coaxial avec celui de l'embrayage 9. Le secteur 51 porte l'aiguille indicatrice de la fonction sélectionnée. Markings on the winding stem 1, on the crown and / or on a casing make it possible to easily visualize the relative position of the crown and the stem of the crown. winding 1 relative to the housing. These marks can be made on one or both parts, by marking or by machining a groove or a groove. It is also possible to determine the selected function by displaying on a watch dial the selected function, as illustrated in FIG. 14 by means of a needle 19 visible from a watch glass. The cam wheel 7 drives a double-pinion 50, which drives a sector 51 (see Figure 8). The pivot axis of the sector is coaxial with that of the clutch 9. The sector 51 carries the indicator needle of the selected function.
Par ailleurs, la perception tactile lors de la rotation de la tige de remontoir 1 permet de détecter un changement de fonction sans avoir à regarder la pièce d'horlogerie notamment dans le cas où aucune aiguille indicatrice de la fonction sélectionnée n'était pas prévue. Moreover, the tactile perception during the rotation of the winding stem 1 makes it possible to detect a change of function without having to look at the timepiece, particularly in the case where no pointer needle of the selected function was not provided.
Les exemples précédents ont permis d'illustrer comment il était possible de sélectionner quatre fonctions différentes grâce au mécanisme de sélection de la présente invention. The previous examples have illustrated how it was possible to select four different functions through the selection mechanism of the present invention.
On peut comprendre comment il serait possible, avec la tige de remontoir dans sa deuxième position, d'envisager la sélection d'une fonction parmi quatre. On emploie le même principe du baladeur, et on ajoute un deuxième baladeur, qui coopérerait avec le pignon 18a de l'embrayage. De cette manière, on crée une deuxième position intermédiaire, qui permet par exemple de régler un réveil. Dans ce cas, la rainure dans la roue à came 7 aurait quatre positions de repos, et par conséquent l'embrayage 9 aurait quatre positions indexées. We can understand how it would be possible, with the winding stem in its second position, to consider the selection of a function among four. We use the same principle of the player, and we added a second player, which cooperates with the pinion 18a of the clutch. In this way, a second intermediate position is created, which makes it possible, for example, to set an alarm clock. In this case, the groove in the cam wheel 7 would have four rest positions, and therefore the clutch 9 would have four indexed positions.
La figure 14 illustre une montre-bracelet comportant un mécanisme selon la présente invention. La montre-bracelet est illustrée sans cadran de manière à pouvoir visualiser le mécanisme et notamment le disque de quantième 56. Dans cet exemple, le quantième peut être visualisé à travers un guichet agencé dans un cadran. Une aiguille indicatrice 19 de la fonction sélectionnée est également illustrée, l'aiguille devant, en fonctionnement normal, être agencé au-dessus d'un cadran de manière à être visible, l'information de la fonction sélectionnée étant inscrite sur ledit cadran. Figure 14 illustrates a wristwatch having a mechanism according to the present invention. The wristwatch is illustrated without a dial so as to be able to visualize the mechanism and in particular the date disk 56. In this example, the date can be viewed through a window arranged in a dial. An indicator needle 19 of the selected function is also illustrated, the needle in front of, in normal operation, being arranged above a dial so as to be visible, the information of the selected function being inscribed on said dial.
