Abstract

Mechanically driven timepiece has a non-circular movement that is combined with a chronograph mechanism comprising levers (5, 6, 10, 21) and a column wheel (4). All the levers of the chronograph mechanism are directly engaged with the column wheel (4), while being subjected to the pressure of return elastic elements such that all the displacements of the levers result from the step by step movement of the column wheel actuated by a single control lever (1).

Description

PIECE D'HORLOGERIE A MOUVEMENT DE FORME MUNI D'UN TIMEPIECE HAVING A SHAPE MOVEMENT PROVIDED WITH A
CHRONOGRAPHECHRONOGRAPH
La présente invention se rapporte à une pièce d' horlo- gerie à mouvement de forme non circulaire muni d'un mécanisme de chronographe comprenant des bascules et une roue à colonnes .The present invention relates to a timepiece with movement of non-circular shape provided with a chronograph mechanism comprising rockers and a column wheel.
Les mouvements de montres-bracelets munis d'un mécanisme de chronographe sont généralement circulaires. La raison principale en est que le mécanisme de chronographe occupe une surface importante. Or dans le cas d'un mouvement de forme non circulaire, la réduction de surface est généralement comprise entre 10% et 15% par rapport à la surface du cercle dans lequel ce mouvement de forme est inscrit. Cette perte de surface pour loger le mécanisme de chronographe s'ajoute à la surface occupée par le mécanisme d'échappement, représentant environ 30% de la surface restante, qui doit être laissée libre pour ne pas gêner le réglage de la montre. On a déjà proposé des mécanismes de chronographes dont toutes les fonctions sont commandées par un seul poussoir qui agit sur une roue à colonnes à laquelle toutes les bascules du mécanisme de chronographe sont mises en prise directe par des ressorts de rappel. Un tel type de mécanisme de chronographe, ramassé autour de la roue à colonnes, permet de concentrer ses différents composants sur une surface plus réduite, mais apparemment personne n'a réalisé jusqu'ici qu'un tel mécanisme pouvait ouvrir de nouvelles possibilités pour incorporer un mécanisme de chronographe à un mouvement de forme non circulaire.Wristwatch movements with a chronograph mechanism are generally circular. The main reason is that the chronograph mechanism occupies a large area. However, in the case of a movement of non-circular shape, the reduction in area is generally between 10% and 15% relative to the area of the circle in which this movement of shape is inscribed. This loss of surface for housing the chronograph mechanism is added to the surface occupied by the escapement mechanism, representing approximately 30% of the remaining surface, which must be left free so as not to interfere with the setting of the watch. Chronograph mechanisms have already been proposed, all of whose functions are controlled by a single pusher which acts on a column wheel to which all the latches of the chronograph mechanism are directly engaged by return springs. Such a type of chronograph mechanism, picked up around the column wheel, allows its various components to be concentrated on a smaller surface, but apparently no one has realized until now that such a mechanism could open up new possibilities for incorporating a chronograph mechanism with a non-circular movement.
Le but de la présente invention est d'apporter une solution à ce problème. A cet effet, la présente invention a pour objet une pièce d'horlogerie à mouvement de forme non circulaire associé à un mécanisme de chronographe tel que défini par la revendication 1. L' avantage de la solution proposée est de permettre de réduire la place occupée par le mécanisme de chronographe et d'offrir ainsi la possibilité de réaliser en particulier une montre-bracelet de forme munie d'un tel mécanisme.The object of the present invention is to provide a solution to this problem. To this end, the subject of the present invention is a timepiece with a movement of non-circular shape associated with a chronograph mechanism as defined by claim 1. The advantage of the proposed solution is that it makes it possible to reduce the space occupied by the chronograph mechanism and thus offer the possibility of making in particular a form wristwatch provided with such a mechanism.
Avantageusement, le mouvement d'horlogerie de forme non circulaire auquel le mécanisme de chronographe est associé est un mouvement comportant un mobile démultiplicateur supplémentaire entre le barillet et la roue de centre aussi appelée grande moyenne, permettant de faire tourner le barillet plus lentement et d' y loger ainsi un ressort moteur sus- ceptible de faire marcher le mouvement pendant environ 10 jours de manière à assurer une période de marche utile de 8 jours .Advantageously, the timepiece movement of non-circular shape with which the chronograph mechanism is associated is a movement comprising an additional reduction mobile between the barrel and the center wheel also called large average, making it possible to rotate the barrel more slowly and In this way, house a mainspring capable of running the movement for approximately 10 days so as to ensure a useful running period of 8 days.
De préférence, avec une réserve de marche portant sur une durée aussi longue, le mouvement est encore muni d'un mécanisme indicateur de réserve de marche.Preferably, with a power reserve for such a long duration, the movement is still provided with a power reserve indicator mechanism.
Avantageusement, le mécanisme de chronographe objet de l'invention est complètement intégré au mouvement de forme, c'est-à-dire que l'ensemble des organes qui le composent sont directement montés sur les différents ponts du rouage sans support intermédiaire permettant une utilisation optimale de l'espace aussi bien en surface qu'en hauteur.Advantageously, the chronograph mechanism that is the subject of the invention is completely integrated into the form movement, that is to say that all of the organs that compose it are directly mounted on the different gearing bridges without intermediate support allowing use. optimal space both above and below ground.
D' autres particularités et avantages de cette invention apparaîtront dans la description qui suit et qui est relative à une forme d'exécution de la pièce d'horlogerie objet de la présente invention, illustrée schématiquement et à titre d'exemple par le dessin annexé.Other particularities and advantages of this invention will appear in the description which follows and which relates to an embodiment of the timepiece object of the present invention, illustrated schematically and by way of example by the appended drawing.

Le mouvement de montre de forme non circulaire illustré par la figure 1 montre en particulier un mécanisme de chronographe, une bascule de commande 1 montée pivotante autour d'une vis à portée la vissée dans le pont de barillet B et dont une extrémité lb est destinée à être reliée à un poussoir unique (non représenté) coaxial à la tige de remontoir T. En variante, comme illustré en traits pointillés sur la figure 3, l'extrémité lb de la bascule 1 pourrait aussi se situer en face de « 2 heures ». L'autre extrémité de cette bascule de commande 1 se termine par un cliquet 2 en prise avec une denture à rochet 4a (figure 3) d'une roue à colonnes 4.The non-circular watch movement illustrated in FIG. 1 shows in particular a chronograph mechanism, a control lever 1 pivotally mounted around a screw carried by the screwed into the barrel bridge B and one end lb of which is intended to be connected to a single pusher (not shown) coaxial with the winding stem T. As a variant, as illustrated in dotted lines on Figure 3, the end lb of the scale 1 could also be located opposite "2 hours". The other end of this control lever 1 ends with a pawl 2 engaged with a ratchet toothing 4a (FIG. 3) of a column wheel 4.
Un ressort de rappel ri tend à ramener la bascule de commande 1 dans une position de repos illustrée par la figure 1, contre une butée ld travaillant avec le bord d'une ouverture ovale le, délimitant ainsi deux positions limites. Un autre ressort de rappel r2 tend à maintenir le cliquet 2 constamment en prise avec la denture à rochet 4a.A return spring ri tends to bring the control lever 1 back into a rest position illustrated in FIG. 1, against a stopper ld working with the edge of an oval opening le, thus delimiting two limit positions. Another return spring r 2 tends to keep the pawl 2 constantly engaged with the ratchet teeth 4a.
Cette roue à colonnes 4 est sélectivement en prise directe avec l'ensemble des bascules du mécanisme de chronographe. L'une de ces bascules est la bascule 5 des marteaux de remise à zéro portant deux marteaux 5a, 5b 'et pivotée autour d'un axe 5c solidaire du pont de barillet B. Cette bascule 5 est en prise avec un ressort de rappel rs qui la presse constamment en direction de la roue à colonnes 4.This column wheel 4 is selectively in direct contact with all the rockers of the chronograph mechanism. One of these rockers is rocker 5 of the reset hammers carrying two hammers 5a, 5b ' and pivoted around an axis 5c secured to the barrel bridge B. This rocker 5 is engaged with a return spring rs which constantly presses it towards the column wheel 4.
Une autre bascule constitue un frein 6 poussé cons- tamment contre la roue à colonnes 4 par un bras élastique 6a venu d' étampage avec le frein 6 et prenant appui contre une butée βc. Ce frein 6 est monté pivotant autour d'une vis à portée 6b vissée dans le pont de barillet B.Another lever constitutes a brake 6 constantly pushed against the column wheel 4 by an elastic arm 6a stamped with the brake 6 and bearing against a stop βc. This brake 6 is pivotally mounted around a bearing screw 6b screwed into the barrel bridge B.
Une troisième bascule est la bascule d'embrayage 10 qui présente une ouverture de pivotement mobile semi-circulaire 10a montée pivotante autour d'une surface circulaire 14a d'une plaquette de pivotement 14, elle-même montée pivotante autour d'une vis 14b vissée dans un pont S de la roue de secondes 15a (figure 11). La position angulaire de cette plaquette de pivotement 14 est réglable autour de l'axe de cette vis 14b à l'aide d'un excentrique 13.A third lever is the clutch lever 10 which has a semi-circular mobile pivoting opening 10a pivotally mounted around a circular surface 14a of a pivoting plate 14, itself pivotally mounted around a screw 14b screwed in a bridge S of the seconds wheel 15a (Figure 11). The angular position of this pivoting plate 14 is adjustable around the axis of this screw 14b using an eccentric 13.
Comme on peut le constater sur la coupe de la figure 11, l'ouverture de pivotement mobile semi-circulaire 10a présente une portée qui débouche sur la face supérieure de la bascule 10. Cette portée sert à retenir la bascule 10 entre le pont de secondes S et une portée entourant la surface circulaire 14b de la plaquette de pivotement 14, débouchant sur la face inférieure de cette plaquette de pivotement 14 et s' ajustant sur la portée complémentaire de l'ouverture de pivotement mobile semi-circulaire 10a de la bascule 10.As can be seen in the section of FIG. 11, the semi-circular mobile pivoting opening 10a has a bearing surface which opens onto the upper face of the rocker 10. This bearing serves to retain the rocker 10 between the seconds bridge S and a bearing surrounding the circular surface 14b of the pivoting plate 14, opening onto the lower face of this pivoting plate 14 and adjusting to the complementary range of the semi-circular mobile pivoting opening 10a of the rocker 10.
La bascule d'embrayage 10 comporte deux parties supé- rieure 10s et inférieure lui assemblées par une vis lOvThe clutch lever 10 has two upper parts 10s and lower assembled by a screw lOv
(figure 11) entre lesquelles une roue d'embrayage 16 est montée pivotante. Cette roue d'embrayage 16 est constamment en prise avec une roue entraîneuse 15 solidaire de l'axe de la roue de secondes 15a. Comme on le voit sur la figure 11, le pont de secondes S est plus haut que le pont du rouage de finissage R. La différence de hauteur est choisie de manière à permettre à la roue entraîneuse 15 et à la bascule d'embrayage 10 de passer au-dessus du pont du rouage de finissage R. Grâce à cette disposition et au système de pivotement de la bascule d'embrayage 10 selon un axe coaxial à celui de la roue de secondes 15a et de la roue entraîneuse 15, la surépaisseur due au mécanisme de chronographe est ramenée à un minimum. Seul l'axe de la roue de secondes 15a portant la roue en- traîneuse nécessite une modification du mouvement d'horlogerie, tout le reste du mécanisme de chronographe se situant hors du mouvement d' horlogerie ne génère aucune modification de ce mouvement .(Figure 11) between which a clutch wheel 16 is pivotally mounted. This clutch wheel 16 is constantly engaged with a driving wheel 15 secured to the axis of the seconds wheel 15a. As can be seen in FIG. 11, the seconds bridge S is higher than the bridge of the gear train R. The difference in height is chosen so as to allow the driving wheel 15 and the clutch lever 10 to pass over the bridge of the gear train R. Thanks to this arrangement and to the pivoting system of the clutch lever 10 along an axis coaxial with that of the seconds wheel 15a and the driving wheel 15, the extra thickness due the chronograph mechanism is reduced to a minimum. Only the axis of the seconds wheel 15a carrying the driving wheel requires a modification of the clockwork movement, all the rest of the chronograph mechanism being outside the clockwork movement does not generate any modification of this movement.
Un ressort de rappel rio (figure 1) pousse la bascule d'embrayage 10 dans le sens des aiguilles d'une montre autour de la surface circulaire de pivotement 14, de sorte que l'extrémité de cette bascule d'embrayage 10 est constamment en contact avec la roue à colonnes 4. Une dernière bascule, dite bascule inter compteurs 21 est montée pivotante autour d'une vis à portée 21a. Un ressort de rappel r2ι pousse cette bascule 21 dans le sens des aiguilles de la montre et presse une de ses extrémités con- tre la roue à colonnes 4 (figure 3) . L'autre extrémité de cette bascule porte une roue intermédiaire 18 du compteur des minutes qui est constamment en prise avec une roue 8 du compteur des minutes dont l'axe de pivotement 8a (figure 10) traverse tout le mouvement pour sortir du côté cadran du mouvement pour porter une aiguille (non représentée) du compteur des minutes . Cette roue 8 du compteur des minutes porte encore une came en forme de cœur 9 (figure 3) destinée à coopérer avec le bras 5a du marteau 5 de remise à zéro lors de la remise à zéro du compteur des minutes. Une roue de chronographe 19 est encore pivotée au centre du mouvement et son axe traverse tout le mouvement pour sortir du côté cadran du mouvement pour porter une aiguille (non représentée) du compteur des secondes. Cette roue de chronographe 19 porte un doigt d'entraînement 17 de la roue intermédiaire 18 du compteur des minutes (figures 5 et 9) entraînant la roue 8 de ce compteur à chaque rotation, c'est-à-dire une fois par minute. Cette roue de chronographe porte aussi une came de remise à zéro en forme de cœur 20A return spring rio (Figure 1) pushes the clutch lever 10 clockwise around the circular pivot surface 14, so that the end of this clutch lever 10 is constantly in contact with the column wheel 4. A last lever, called inter-meter lever 21 is pivotally mounted around a bearing screw 21a. A return spring r 2 ι pushes this rocker 21 clockwise and presses one of its ends against the column wheel 4 (FIG. 3). The other end of this lever carries an intermediate wheel 18 of the minute counter which is constantly engaged with a wheel 8 of the minute counter whose pivot axis 8a (FIG. 10) crosses the entire movement to exit from the dial side of the movement to carry a minute counter hand (not shown). This wheel 8 of the minute counter still carries a heart-shaped cam 9 (FIG. 3) intended to cooperate with the arm 5a of the hammer 5 for resetting to zero during the resetting of the minute counter. A chronograph wheel 19 is still pivoted in the center of the movement and its axis crosses the entire movement to exit the dial side of the movement to carry a hand (not shown) of the seconds counter. This chronograph wheel 19 carries a drive finger 17 of the intermediate wheel 18 of the minute counter (FIGS. 5 and 9) driving the wheel 8 of this counter at each rotation, that is to say once per minute. This chronograph wheel also carries a heart-shaped reset cam 20
(figure 3) destinée à coopérer avec le bras 5b du marteau de remise à zéro 5.(Figure 3) intended to cooperate with the arm 5b of the reset hammer 5.
Un ressort sautoir 3 est en prise avec la denture à rochet 4a de la roue à colonnes et un ressort sautoir 7 est en prise avec la roue 8 du compteur des minutes.A jumper spring 3 is engaged with the ratchet teeth 4a of the column wheel and a jumper spring 7 is engaged with the wheel 8 of the minute counter.
La pénétration de la roue d'embrayage 16 portée par la bascule d'embrayage 10 est réglable au moyen d'une butée 11 constituée par un excentrique, servant à limiter le pivotement de la bascule d'embrayage 10 dans le sens des aiguilles d'une montre, permettant ainsi de régler la pénétration de la denture de la roue d' embrayage dans celle de la roue de chronographe 19.The penetration of the clutch wheel 16 carried by the clutch lever 10 is adjustable by means of a stop 11 constituted by an eccentric, serving to limit the pivoting of the clutch lever 10 in the clockwise direction. a watch, allowing you to adjust the penetration of the toothing of the clutch wheel to that of the chronograph wheel 19.
Une autre butée excentrique 12 sert à limiter le pivotement de la bascule intermédiaire 21 dans le sens des ai- guilles d' une montre et par conséquent la pénétration du doigt d' entraînement 17 dans la denture de la roue intermédiaire 18.Another eccentric stop 12 serves to limit the pivoting of the intermediate lever 21 in the clockwise direction and consequently the penetration of the drive finger 17 into the teeth of the intermediate wheel 18.
La figure 2 montre le rouage du mouvement de la montre. Outre les roues habituelles que l'on retrouve dans tous les mouvements d'horlogerie mécaniques, à savoir, les roues de centre 23 de moyenne 25 de seconde 26 et d'échappement 27, ce mouvement comporte un mobile supplémentaire 24 entre la denture du barillet 22 renfermant le ressort moteur (non représenté) et le pignon 23a de la roue de centre 23. Ce mobi- le supplémentaire 24 augmente la démultiplication entre le barillet 22 et la roue de centre 23, de sorte que le barillet 22 tourne plus lentement que dans un mouvement classique, ce qui permet d'augmenter la réserve de marche de la montre d'environ deux jours pour une montre classique à environ dix jours dans ce cas, soit 8 jours utiles.Figure 2 shows the cog of the watch movement. In addition to the usual wheels that are found in all mechanical watch movements, namely, the center wheels 23 with an average 25 of a second 26 and an escapement 27, this movement includes an additional mobile 24 between the teeth of the barrel 22 enclosing the mainspring (not shown) and the pinion 23a of the center wheel 23. This additional movable 24 increases the reduction ratio between the barrel 22 and the center wheel 23, so that the barrel 22 rotates more slowly than in a classic movement, which makes it possible to increase the power reserve of the watch from around two days for a classic watch to around ten days in this case, ie 8 useful days.
Etant donné l'importance de la réserve de marche, il est utile d' avoir un indicateur de réserve de marche pour que l'utilisateur sache quand il doit remonter sa montre. Le rouage de l'indicateur de réserve de marche se trouve essen- tiellement du côté cadran du mouvement (figures 13 et 14). De l'autre côté, ce rouage comporte un renvoi 37 en prise d'une part avec le rochet 36 du barillet 22 et d'autre part avec une roue de différentiel 38, dont l'arbre 38a traverse le mouvement et comporte un carré 38b en prise avec un renvoi 31 engrenant avec un satellite 32 monté pivotant sur une tige 30a d'une couronne 30 portant le différentiel. Cette couronne 30 est en prise avec un renvoi 29 qui engrène avec un pignon 28a d'une roue 28 coaxiale au barillet 22 et qui est en liaison cinématique avec le barillet 22 grâce à un double pignon 39 engrenant simultanément avec la denture du barillet 22 et celle de la roue 28.Given the importance of the power reserve, it is useful to have a power reserve indicator so that the user knows when he has to wind his watch. The cog in the power reserve indicator is mainly on the dial side of the movement (Figures 13 and 14). On the other side, this train comprises a gear 37 engaged on the one hand with the ratchet 36 of the barrel 22 and on the other hand with a differential wheel 38, the shaft 38a of which crosses the movement and includes a square 38b engaged with a reference 31 meshing with a satellite 32 pivotally mounted on a rod 30a of a crown 30 carrying the differential. This crown 30 is engaged with a reference 29 which meshes with a pinion 28a of a wheel 28 coaxial with the barrel 22 and which is in kinematic connection with the barrel 22 by virtue of a double pinion 39 meshing simultaneously with the toothing of the barrel 22 and that of the wheel 28.
Le pignon 32a du satellite 32 engrène avec une roue in- termédiaire 33 qui engrène avec une roue d'entraînement 34 dont le pignon 34a engrène avec un secteur denté 35 portant l'indicateur de réserve de marche (non représenté) qui se déplace sur un angle de 90° par exemple, entre l'armage et le désarmage du ressort moteur contenu dans le barillet 22. La figure 13 indique par des flèches les sens de rotations respectifs des différents mobiles du rouage indicateur de réserve de marche durant la phase d' ar age du ressort de barillet. Les mobiles sans flèches correspondent à ceux qui sont fixes, c'est-à-dire le barillet 22, le double pignon 39, la roue 28 coaxiale au barillet 22, le renvoi 29 et la couronne de différentiel 30.The pinion 32a of the satellite 32 meshes with an intermediate wheel 33 which meshes with a drive wheel 34 whose pinion 34a meshes with a toothed sector 35 carrying the power reserve indicator (not shown) which moves on a angle of 90 ° for example, between the winding and the winding of the mainspring contained in the barrel 22. Figure 13 indicates by arrows the respective directions of rotation of the various moving parts of the gear train indicating power reserve during the phase of ar age of the barrel spring. The mobiles without arrows correspond to those which are fixed, that is to say the barrel 22, the double pinion 39, the wheel 28 coaxial with the barrel 22, the reference 29 and the differential crown 30.
La figure 14 indique par des flèches les sens de rotations respectifs des mobiles du rouage indicateur de réserve de marche durant la phase de désarmage du ressort de baril- let. Les mobiles qui restent immobiles durant cette phase n'ont pas de flèches, il s'agit du rochet 36, du renvoi 37, de la roue de différentiel 38 et du renvoi entraîneur de satellite 31 solidaire de la roue de différentiel 38.FIG. 14 indicates by arrows the respective directions of rotation of the moving parts of the power reserve indicator gear train during the disarming phase of the barrel spring. The mobiles which remain stationary during this phase have no arrows, these are the ratchet 36, the reference 37, the differential wheel 38 and the satellite drive return 31 secured to the differential wheel 38.
Les figures 3 à 8 montrent le seul mécanisme de chrono- graphe au cours des différentes phases d'un cycle complet de fonctionnement. La figure 3 montre ce mécanisme remis à zéro. Les flèches indiquent quels sont les organes en mouvement et les sens respectifs des déplacements. Tous les organes du mécanisme sont au repos à l'exception de la roue d'entraînement 15 et de la roue d'embrayage 16 qui sont en liaison cinématique avec le rouage 22-27 du mouvement de la montre . La figure 4 illustre la phase de mise en marche du mécanisme de chronographe. Les flèches montrent quels sont les organes en mouvement et leurs sens de déplacements respectifs. Cette mise en marche est commandée par la bascule 1 consécutivement à une pression exercée sur son extrémité adjacente à la tige de remontoir T (figure 1) . Cette pression fait tourner de 20° la roue à colonnes 4 dans le sens des aiguilles d'une montre et cette rotation provoque le déplacement de la bascule 5 dans le sens des flèches et la libération des marteaux 5a, 5b, ainsi que le déplacement des bascules d'embrayage 10 et inter compteur 21 dans les sens respectifs des flèches.Figures 3 to 8 show the only chronograph mechanism during the different phases of a complete operating cycle. Figure 3 shows this mechanism reset. The arrows indicate which are the moving parts and the respective directions of movement. All the organs of the mechanism are at rest except for the drive wheel 15 and the clutch wheel 16 which are in kinematic connection with the gear train 22-27 of the watch movement. Figure 4 illustrates the start-up phase of the chronograph mechanism. The arrows show which are the moving parts and their respective directions of movement. This start-up is controlled by the lever 1 following a pressure exerted on its end adjacent to the winding stem T (Figure 1). This pressure turns the column wheel 4 by 20 ° clockwise and this rotation causes the rocker 5 to move in the direction of the arrows and release the hammers 5a, 5b, as well as the movement of the clutch shoes 10 and inter counter 21 in the respective directions of the arrows.
La figure 5 montre le chronographe en marche. Les leviers en prise avec les colonnes de la roue à colonnes 4 sont dans les mêmes positions que précédemment, et toutes les roues du mécanisme chronographe sont en mouvement dans les sens respectifs indiqués par les flèches. La bascule de commande 1 'est ramenée dans la position de repos. En ce qui concerne la roue intermédiaire 18 et la roue du compteur de minutes 8 elles sont entraînées pas à pas par le doigt 17 de la roue de chronographe 19, une fois par révolution de cette roue 19, c'est-à-dire une fois par minute.Figure 5 shows the chronograph running. The levers engaged with the columns of the column wheel 4 are in the same positions as above, and all the wheels of the chronograph mechanism are in movement in the respective directions indicated by the arrows. The control lever 1 ' is returned to the rest position. As regards the intermediate wheel 18 and the minute counter wheel 8, they are driven step by step by the finger 17 of the chronograph wheel 19, once per revolution of this wheel 19, that is to say a times per minute.
Le passage de la phase de la figure 5 à celle de la figure 6 correspond au passage de la mise en arrêt du rouage de chronographe consécutivement à un nouvel actionnement de la bascule de commande 1. Au cours de cette phase, le frein 6 se déplace dans le sens de la flèche et vient en appui contre la roue de chronographe 19 qu'il immobilise. Simultanément, la bascule d'embrayage 10 se déplace dans le sens de la flèche séparant la roue d'embrayage 16 de la roue de compteur 19.The passage from the phase of FIG. 5 to that of FIG. 6 corresponds to the passage of the stopping of the chronograph train following a new actuation of the control lever 1. During this phase, the brake 6 moves in the direction of the arrow and bears against the chronograph wheel 19 which it immobilizes. Simultaneously, the clutch lever 10 moves in the direction of the arrow separating the clutch wheel 16 from the counter wheel 19.
La figure 7 montre le chronographe arrêté, c'est-à-dire que par rapport à la figure 6, on a cessé d'exercer une pression sur la bascule de commande 1, de sorte qu'elle est revenue en position de repos sous la pression du ressort de rappel ri, mettant ainsi le cliquet 2 en position prête pour actionner la roue à colonnes d'un nouveau pas de 20°. Dans cette position, le frein 6 retient la roue de chronographe 19 dans la position dans laquelle le mécanisme de chronographe a été arrêté, permettant la lecture du temps mesuré par ce mécanisme entre sa mise en marche et son arrêt.Figure 7 shows the chronograph stopped, that is to say that compared to Figure 6, we have stopped exercising pressure on the control lever 1, so that it returned to the rest position under the pressure of the return spring laughed, thus putting the pawl 2 in the position ready to actuate the column wheel in a new step of 20 ° . In this position, the brake 6 retains the chronograph wheel 19 in the position in which the chronograph mechanism has been stopped, allowing the time measured by this mechanism to be read between its start and stop.
La dernière fonction consiste à remettre à zéro les aiguilles du compteur de secondes et de celui des minutes. Elle est illustrée par la figure 8 dans laquelle on voit que le marteau 5 est poussé contre les cames en cœurs 9 et 20. Simultanément, le frein 6 libère la roue de chronographe 19, la bascule 21 libère le doigt 17, permettant ainsi la remise à zéro des aiguilles des compteurs de minutes et de secondes.The last function consists in resetting the hands of the seconds and minutes counter. It is illustrated by FIG. 8 in which it can be seen that the hammer 5 is pushed against the cams with cores 9 and 20. Simultaneously, the brake 6 releases the chronograph wheel 19, the rocker 21 releases the finger 17, thus allowing delivery at zero of the minutes and seconds counters.
La figure 3 montre les positions respectives des organes du mécanisme de chronographe après la remise à zéro, une fois que la bascule de commande 1 a été ramenée en position de repos par le ressort de rappel ri. FIG. 3 shows the respective positions of the members of the chronograph mechanism after resetting to zero, once the control lever 1 has been returned to the rest position by the return spring ri.
