On connaît par les documents EP 0 927 383 et EP 0 931 282 une pièce d'horlogerie dans laquelle le déplacement axial d'une tige de commande manuelle d'une position neutre à une position de réglage de l'heure arrête le mouvement d'horlogerie et remet automatiquement à zéro l'aiguille des secondes.We know from documents EP 0 927 383 and EP 0 931 282 a timepiece in which the axial displacement of a manual control rod from a neutral position to a time setting position stops the clockwork and automatically resets the second hand.

La présente invention vise à proposer un dispositif de mise à l'heure capable de remettre à zéro l'aiguille des secondes d'une pièce d'horlogerie lorsqu'un organe de commande manuel est dans une position de réglage de l'heure, mais dans lequel la remise à zéro de l'aiguille des secondes s'effectue seulement si et au moment où l'utilisateur le souhaite.The present invention aims at providing a time-setting device capable of resetting the seconds hand of a timepiece when a manual control member is in a time setting position, but in which the reset of the second hand takes place only if and when the user wishes.

A cette fin il est prévu un dispositif de mise à l'heure selon la revendication 1 annexée, des modes de réalisation particuliers de ce dispositif étant définis dans les revendications dépendantes. La présente invention propose également une pièce d'horlogerie, par exemple une montre-bracelet, comprenant un tel dispositif de mise à l'heure.For this purpose there is provided a time setting device according to claim 1 attached, particular embodiments of this device being defined in the dependent claims. The present invention also proposes a timepiece, for example a wristwatch, comprising such a device for setting the time.

Aux figures 1 à 3 est représenté un dispositif selon l'invention de mise à l'heure d'une pièce d'horlogerie telle qu'une montre-bracelet. La pièce d'horlogerie comprend des aiguilles centrales (non représentées) indicatrices des heures et des minutes et une petite aiguille indicatrice des secondes 1, excentrée par rapport aux aiguilles des heures et des minutes. Le dispositif de mise à l'heure selon l'invention comprend un premier organe de commande manuel 2 et un mécanisme 3 de remise à zéro de l'aiguille indicatrice des secondes 1, connecté au premier organe de commande manuel 2.FIGS. 1 to 3 show a device according to the invention for setting a timepiece such as a wristwatch. The timepiece comprises central needles (not shown) indicating the hours and minutes and a small seconds indicator hand 1, eccentric to the hour and minute hands. The time setting device according to the invention comprises a first manual control member 2 and a reset mechanism 3 of the seconds indicator hand 1, connected to the first manual control member 2.

Le premier organe de commande manuel 2 se présente sous la forme conventionnelle d'une tige terminée par une couronne 5 manipulable par un utilisateur. La tige 2, dite tige de remontoir ou de réglage, peut occuper trois positions axiales distinctes, à savoir une position neutre ou de remontage (figure 1), une position tirée intermédiaire de réglage du quantième (figure 2) et une position tirée extrême de mise à l'heure (figure 3). Dans ces trois positions axiales de la tige 2 respectivement, l'utilisateur peut, par l'intermédiaire de mécanismes connus en soi et non représentés, remonter le ressort moteur de la pièce d'horlogerie, régler un affichage de quantième de la pièce d'horlogerie et régler les aiguilles indicatrices des heures et des minutes, en tournant la tige 2 autour de son axe.The first manual control member 2 is in the conventional form of a rod terminated by a crown 5 which can be manipulated by a user. The stem 2, referred to as a winding or adjustment rod, can occupy three distinct axial positions, namely a neutral or winding position (FIG. 1), an intermediate drawn adjustment position of the date (FIG. 2) and an extreme end position of setting the time (Figure 3). In these three axial positions of the rod 2 respectively, the user can, through mechanisms known per se and not shown, reassemble the motor spring of the timepiece, set a date display of the workpiece. watchmaking and set the hour and minute hands by turning the rod 2 around its axis.

Le mécanisme 3 de remise à zéro de l'aiguille des secondes 1 comprend un second organe de commande manuel, du type bouton poussoir, représenté schématiquement en 6, une bascule de commande 7 soumise à l'action d'un ressort 8, un marteau 9 soumis à l'action d'un ressort 10, une came 11 en forme de coeur montée sur l'axe de l'aiguille des secondes 1 et solidaire de cette dernière, une seconde bascule 19 et une tirette 20.The mechanism 3 for resetting the seconds hand 1 comprises a second manual control member, of the push button type, shown schematically at 6, a control lever 7 subjected to the action of a spring 8, a hammer 9 subjected to the action of a spring 10, a cam 11 in the shape of a heart mounted on the axis of the seconds hand 1 and integral with the latter, a second lever 19 and a pull tab 20.

La bascule de commande 7 est coudée au niveau de son pivot 12 et présente une première extrémité maintenue par le ressort 8 en contact contre un plot mobile 13 commandé par le bouton poussoir 6 et une seconde extrémité qui porte un tenon cylindrique 14 faisant saillie en dehors du plan du dessin. La bascule de commande 7 peut être pivotée d'une position de repos (figures 1 et 2 ; figure 3 : position en trait pointillé) à une position de commande de remise à zéro (figure 3 : position en trait plein) par un actionnement du bouton poussoir 6, actionnement qui translate le plot 13 de sa position montrée en trait pointillé à la figure 3 à sa position montrée en trait plein et pousse ainsi la première l'extrémité de la bascule 12. Une fois la pression sur le bouton poussoir 6 relâchée, la bascule de commande 7 revient à sa position de repos sous l'action du ressort 8. En position de repos de la bascule de commande 7, le tenon 14 est engagé dans un logement 15 en forme de U et à fond semi-cylindrique de taille adaptée pratiqué dans une extrémité du marteau 9 et retient de cette manière le marteau 9 à l'encontre de l'action exercée par le ressort 10, action qui tend à faire pivoter le marteau 9 vers le coeur 11 autour d'un pivot 16. Lorsque la bascule de commande 7 est dans sa position pivotée de commande de remise à zéro, le tenon 14 est en dehors du logement 15 du marteau 9 et ne retient donc plus ce dernier.The control rocker 7 is bent at its pivot 12 and has a first end held by the spring 8 in contact against a movable pin 13 controlled by the push button 6 and a second end which carries a cylindrical pin 14 protruding outside from the drawing plane. The control lever 7 can be pivoted from a rest position (FIGS. 1 and 2, FIG. 3: dashed line position) to a reset control position (FIG. 3: position in solid lines) by actuation of FIG. push button 6, actuation which translates the pad 13 from its position shown in dotted line in Figure 3 to its position shown in solid lines and thus pushes the first end of the rocker 12. Once the pressure on the push button 6 released, the control rocker 7 returns to its rest position under the action of the spring 8. In the rest position of the control rocker 7, the post 14 is engaged in a U-shaped housing 15 and semicircle cylindrical adapted size made in one end of the hammer 9 and in this way holds the hammer 9 against the action exerted by the spring 10, action which tends to rotate the hammer 9 to the heart 11 around a 16. When the comm switch ande 7 is in its pivoted reset control position, the post 14 is outside the housing 15 of the hammer 9 and therefore no longer retains the latter.

De l'autre côté du pivot 16 par rapport au logement 15, le marteau 9 se divise en deux bras 17, 18. Le premier bras 17 comprend une face de percussion 19 destinée à coopérer avec le coeur 11. Le second bras 18 coopère avec la seconde bascule 19, d'une manière décrite ci-dessous.On the other side of the pivot 16 relative to the housing 15, the hammer 9 is divided into two arms 17, 18. The first arm 17 comprises a striking face 19 intended to cooperate with the core 11. The second arm 18 cooperates with the second flip-flop 19, in a manner described below.

De façon connue en soi, la tirette 20 se présente sous la forme d'un levier comportant un tenon 21 logé dans une gorge de la tige de remontoir 2. Une goupille 22 solidaire de la tirette 20 est logée dans une lumière oblongue 23 pratiquée dans une extrémité de la bascule 19. La coopération entre la goupille 22 et la lumière 23 permet à la tirette 20 de faire pivoter la bascule 19 en fonction de la position axiale de la tige de remontoir 2. La bascule 19 peut ainsi occuper trois positions angulaires différentes, correspondant aux trois positions axiales de la tige de remontoir 2. Dans ses deux premières positions angulaires (figures 1 et 2) correspondant aux positions neutre et de réglage du quantième de la tige de remontoir 2, la bascule 19 coopère, par une extrémité 24 opposée à son extrémité recevant la goupille 22 et située de l'autre côté de son pivot 25, avec une face de butée légèrement concave 26 du bras 18 du marteau 9 pour retenir le marteau 9 à l'encontre de l'action exercée par le ressort 10, action qui, comme indiqué plus haut, tend à faire pivoter le marteau 9 vers le coeur 11. La face de butée 26 a un profil en arc de cercle dont le centre, lorsque le marteau 9 est retenu par la bascule 19 (figures 1 et 2), est confondu avec le pivot 25 de la bascule 19. Ainsi, le pivotement de la bascule 19 entre ses deux premières positions angulaires n'a aucun effet sur le marteau 9, qui reste empêché de pivoter vers le coeur 11. Dans la troisième position de la bascule 19 (figure 3), correspondant à la position de mise à l'heure de la tige 2, l'extrémité 24 de la bascule 19 n'est plus en contact avec le bras 18 et n'empêche plus le marteau 9 de pivoter vers le coeur 11.In a manner known per se, the pull tab 20 is in the form of a lever having a pin 21 housed in a groove of the winding stem 2. A pin 22 integral with the pull tab 20 is housed in an oblong slot 23 formed in one end of the rocker 19. The cooperation between the pin 22 and the light 23 allows the pull tab 20 to pivot the rocker 19 according to the axial position of the winding stem 2. The rocker 19 can thus occupy three different angular positions corresponding to the three axial positions of the winding stem 2. In its first two angular positions (FIGS. 1 and 2) corresponding to the neutral and setting positions of the date of the winding stem 2, the rocker 19 cooperates, for example an end 24 opposite its end receiving the pin 22 and located on the other side of its pivot 25, with a slightly concave abutment face 26 of the arm 18 of the hammer 9 to retain the hammer 9 against the action exerted by the spring 10, action which, as indicated above, tends to pivot the hammer 9 towards the heart 11. The abutment face 26 has an arcuate profile whose center, when the hammer 9 is retained by the flip-flop 19 (FIGS. 1 and 2) coincides with pivot 25 of flip-flop 19. Thus, the pivoting of flip-flop 19 between its two first angular positions has no effect on hammer 9, which remains prevented from pivoting towards the heart 11. In the third position of the rocker 19 (Figure 3), corresponding to the time setting position of the rod 2, the end 24 of the rocker 19 is no longer in contact with the arm 18 and does not prevent more the hammer 9 to pivot towards the heart 11.

Du même côté du pivot 25 que son extrémité recevant la goupille 22, la bascule 19 comprend un logement en forme de U et à fond semi-cylindrique 27 dans lequel est articulée une extrémité cylindrique 28 d'un levier d'arrêt 29. Le pivotement de la bascule 19 d'une de ses positions à une autre fait glisser l'extrémité 28 du levier 29 dans le logement 27 et entraîne le levier 29 en pivotement autour de son pivot 30. Le levier 29 peut ainsi occuper trois positions angulaires différentes, correspondant aux trois positions axiales de la tige de remontoir 2. Dans les deux positions du levier 29 qui correspondent aux positions neutre et de réglage du quantième de la tige 2 (figures 1 et 2), le levier 29 est hors de contact avec le balancier de la pièce d'horlogerie, désigné par 31. Dans la troisième position du levier 29, correspondant à la position de mise à l'heure de la tige 2, une goupille 32 solidaire de l'extrémité du levier 29 opposée à l'extrémité 28 est en contact avec la périphérie du balancier 31 et bloque la rotation de ce dernier.On the same side of the pivot 25 as its end receiving the pin 22, the rocker 19 comprises a U-shaped housing with a semi-cylindrical bottom 27 in which is articulated a cylindrical end 28 of a stop lever 29. The pivoting of the rocker 19 from one of its positions to another slides the end 28 of the lever 29 in the housing 27 and causes the lever 29 to pivot about its pivot 30. The lever 29 can thus occupy three different angular positions, corresponding to the three axial positions of the winding stem 2. In the two positions of the lever 29 which correspond to the neutral and date adjustment positions of the rod 2 (Figures 1 and 2), the lever 29 is out of contact with the balance of the timepiece, designated 31. In the third position of the lever 29, corresponding to the time setting position of the rod 2, a pin 32 integral with the end of the lever 29 opposite the end 28 is in contact with the periphery of the balance 31 and blocks the rotation of the latter.

Le mécanisme selon l'invention fonctionne de la manière suivante.The mechanism according to the invention operates as follows.

Lorsque la tige de remontoir 2 est dans sa position neutre (figure 1), l'extrémité 24 de la bascule 19 est en contact avec la face de butée 26 du marteau 9 en un point situé à proximité de l'extrémité distale du bras 18, ce qui retient le marteau 9 et l'empêche donc de pivoter vers le coeur 11. La goupille 32 du levier 29 est hors de contact avec le balancier 31, qui peut donc osciller normalement pour permettre la rotation des aiguilles des heures, minutes et secondes. Dans cette position de la tige 2, lorsque l'utilisateur presse le bouton poussoir 6, le tenon 14 de la bascule de commande 7 sort du logement 15 du marteau 9, mais ceci n'a aucun effet sur la position du marteau 9, retenu par la bascule 19, et donc sur la position de l'aiguille des secondes 1, qui continue à tourner normalement.When the winding stem 2 is in its neutral position (FIG. 1), the end 24 of the rocker 19 is in contact with the abutment face 26 of the hammer 9 at a point situated near the distal end of the arm 18 , which holds the hammer 9 and thus prevents it from pivoting towards the heart 11. The pin 32 of the lever 29 is out of contact with the balance 31, which can therefore oscillate normally to allow the rotation of the hours, minutes and seconds. In this position of the rod 2, when the user presses the push button 6, the post 14 of the control rocker 7 leaves the housing 15 of the hammer 9, but this has no effect on the position of the hammer 9, retained by the rocker 19, and therefore on the position of the seconds hand 1, which continues to rotate normally.

Lorsque la tige de remontoir 2 est tirée de sa position neutre à sa position intermédiaire de réglage du quantième (figure 2), l'extrémité 24 de la bascule 19 glisse sur la face de butée 26 du marteau 9 vers l'extrémité proximale du bras 18 jusqu'à un point déterminé de cette face 26. L'extrémité 24 de la bascule 19 reste ainsi en contact avec le bras 18, ce qui retient le marteau 9 et l'empêche donc encore de pivoter vers le coeur 11. Dans le même temps, la goupille 32 du levier 29 se rapproche du balancier 31 mais tout en restant hors de contact avec celui-ci. Le balancier 31 peut donc continuer à osciller normalement pour permettre la rotation des aiguilles des heures, minutes et secondes. Dans la position intermédiaire de réglage du quantième de la tige 2, lorsque l'utilisateur presse le bouton poussoir 6, le tenon 14 de la bascule de commande 7 sort du logement 15 du marteau 9, mais ceci n'a aucun effet sur la position du marteau 9, retenu par la bascule 19, et donc sur la position de l'aiguille des heures 1, qui continue à tourner normalement.When the winding stem 2 is pulled from its neutral position to its intermediate date adjustment position (FIG. 2), the end 24 of the rocker 19 slides on the abutment face 26 of the hammer 9 towards the proximal end of the arm 18 to a given point of this face 26. The end 24 of the rocker 19 thus remains in contact with the arm 18, which retains the hammer 9 and thus still prevents it from pivoting towards the heart 11. In the same time, the pin 32 of the lever 29 approaches the balance 31 but while remaining out of contact with it. The rocker 31 can therefore continue to oscillate normally to allow the rotation of the hours, minutes and seconds hands. In the intermediate date setting position of the rod 2, when the user presses the push button 6, the pin 14 of the control rocker 7 out of the housing 15 of the hammer 9, but this has no effect on the position hammer 9, retained by the rocker 19, and therefore the position of the hour hand 1, which continues to rotate normally.

Lorsque la tige de remontoir 2 est tirée de sa position intermédiaire de réglage du quantième à sa position extrême de mise à l'heure (figure 3), la goupille 32 du levier 29 vient au contact du balancier 31 pour l'arrêter, ce qui arrête les aiguilles des heures, minutes et secondes. En même temps, l'extrémité 24 de la bascule 19 pivote vers l'extrémité proximale du bras 18 du marteau 9 et perd le contact avec le marteau 9 dès qu'elle quitte la face de butée 26. Le marteau 9 n'est alors plus retenu par la bascule 19, mais seulement par le tenon 14 de la bascule de commande 7 logé dans le logement 15. Dans la position extrême de mise à l'heure de la tige 2, lorsque l'utilisateur presse le bouton poussoir 6, le tenon 14 sort du logement 15. N'étant plus retenu par le tenon 14, le marteau 9, entraîné par le ressort 10, vient alors frapper le coeur 11, qui se met à tourner en glissant sur la face de percussion 19 du marteau 9 jusqu'à ce que la base du coeur 11 soit en contact avec la face de percussion 19, remettant ainsi à zéro l'aiguille des secondes 1. Cette remise à zéro de l'aiguille des secondes 1 est rendue possible, de manière connue en soi, par le fait que le pignon et la roue des secondes qui engrènent avec le rouage de finissage sont montés à friction sur l'axe de l'aiguille des secondes 1, axe auquel sont fixés le coeur 11 et l'aiguille des secondes 1.When the winding stem 2 is pulled from its intermediate date setting position to its extreme position setting time (Figure 3), the pin 32 of the lever 29 comes into contact with the balance 31 to stop, which stop the hands for hours, minutes and seconds. At the same time, the end 24 of the rocker 19 pivots towards the proximal end of the arm 18 of the hammer 9 and loses contact with the hammer 9 as soon as it leaves the stop face 26. The hammer 9 is then more retained by the rocker 19, but only by the pin 14 of the control rocker 7 housed in the housing 15. In the extreme position setting time of the rod 2, when the user presses the push button 6, the tenon 14 comes out of the housing 15. Since it is no longer retained by the post 14, the hammer 9, driven by the spring 10, then hits the core 11, which begins to rotate by sliding on the percussion face 19 of the hammer 9 until the base of the heart 11 is in contact with the percussion face 19, thereby resetting the second hand 1. This reset of the second hand 1 is made possible, in a known manner in itself, by the fact that the pinion and the seconds wheel that meshes with the finishing gear are my friction plates on the axis of the seconds hand 1, axis to which are fixed the heart 11 and the seconds hand 1.

Après une remise à zéro de l'aiguille des secondes 1, le retour du marteau 9 dans sa position initiale s'effectue en repoussant la tige de remontoir 2 de sa position extrême de mise à l'heure à sa position intermédiaire de réglage du quantième. Pendant ce déplacement de la tige de remontoir 2, l'extrémité 24 de la bascule 19 remonte vers l'extrémité distale du bras 18 en glissant sur et poussant une face légèrement concave 33 du bras 18 adjacente à la face de butée 26 et située plus précisément entre l'extrémité proximale du bras 18 et la face de butée 26. La poussée qu'exerce l'extrémité 24 de la bascule 19 sur la face 33 relève le marteau 9 à l'encontre de l'action du ressort 10 jusqu'à ce que le marteau 9 retrouve sa position initiale où l'extrémité 24 de la bascule 19 est en contact avec la face de butée 26 et le tenon 14 de la bascule de commande 7 en position de repos est dans le logement 15. Lorsque le marteau 9 revient à sa position initiale, il fait pivoter la bascule de commande 7 en agissant sur le tenon 14 pour permettre au tenon 14 de se loger dans le logement 15, c'est-à-dire de retrouver sa position initiale.After resetting the seconds hand 1, the hammer 9 is returned to its initial position by pushing the winding stem 2 from its extreme setting position to its intermediate date setting position. . During this movement of the winding stem 2, the end 24 of the rocker 19 rises towards the distal end of the arm 18 by sliding on and pushing a slightly concave face 33 of the arm 18 adjacent to the abutment face 26 and located more precisely between the proximal end of the arm 18 and the abutment face 26. The thrust exerted by the end 24 of the rocker 19 on the face 33 raises the hammer 9 against the action of the spring 10 until the hammer 9 returns to its initial position where the end 24 of the rocker 19 is in contact with the stop face 26 and the pin 14 of the control rocker 7 in the rest position is in the housing 15. When the hammer 9 returns to its initial position, it pivots the control lever 7 by acting on the pin 14 for allow the post 14 to be housed in the housing 15, that is to say to find its initial position.

On appréciera que, dans le dispositif de mise à l'heure tel que décrit ci-dessus, la remise à zéro de l'aiguille des secondes 1 lorsque la tige de remontoir 2 est dans sa position axiale de mise à l'heure ne s'effectue pas automatiquement mais sur demande de l'utilisateur, par un appui sur le bouton poussoir 6. L'utilisateur peut ainsi décider de remettre à zéro ou non l'aiguille des secondes 1. Il peut aussi décider du moment où l'aiguille des secondes 1 sera remise à zéro, par exemple après le réglage des aiguilles des heures et des minutes. De plus, la fonction de remise à zéro de l'aiguille des secondes 1 reste liée à la position axiale de la tige de remontoir 2, ce qui permet par exemple de ne rendre possible la remise à zéro de l'aiguille des secondes 1 que lorsque la tige de remontoir 2 est dans sa position de mise à l'heure.It will be appreciated that, in the time setting device as described above, the reset of the seconds hand 1 when the winding stem 2 is in its axial position of setting time does not automatically but at the request of the user, by pressing the push button 6. The user can thus decide to reset or not the seconds hand 1. It can also decide when the needle seconds 1 will be reset, for example after setting the hour and minute hands. In addition, the reset function of the seconds hand 1 remains linked to the axial position of the winding stem 2, which makes it possible, for example, to make it possible to reset the seconds hand 1 only when the winding stem 2 is in its setting position.
