Definitions
- the present invention relates to a watch with a mechanism for winding and correcting at least two indicator members, comprising a control rod, a pull tab engaged on the one hand with this control rod, on the other hand with a spring jumper defining three axial positions of said control rod, corresponding to those of reassembly, of correction of at least one indicator member of a function derived from the time, respectively of setting time, said control rod carrying a winder pinion and a sliding pinion engaged with a spring-biased rocker and connected to said puller for selectively engaging said pinion gear in engagement with said winder pinion and with a timer train in the extreme positions of said control rod.
- Such mechanisms are known and used in all mechanical timepieces including an indicator of a function derived from the hour, such as the calendar of the month, the days of the week, the phases of the moon, the different time zones schedules in particular.
- control of these various functions requires the axial displacement of the control rod, generally called the winding stem, in three positions, the first position, that is to say the one where the control rod is in the pushed position towards the center of the movement. is the usual winding position, one of the two remaining positions is that of the date correction or similar derivative function, while the other of the remaining positions is that of setting the time.
- the winding pinion pivoted on the control rod is only used for reassembly when it is engaged with the sliding pinion and the latter is moved axially in the other two positions to engage a return connected alternately with the time-setting train and with the date-setting train or any other derived function.
- a rocker which, in the correction position, can move in the direction of rotation of the control rod, alternately between two angular positions, to bring the corrective gear engaged with the date indicator or with that of the days.
- Such correction mechanisms are described, for example, in GB 1'234'004, in FR 2'169'861 or else in CH 571'734.
- the winding pinion is used only for reassembly, so that the sliding pinion must control two functions.
- the sliding pinion with its two end teeth, is the member which, being moved axially on a non-circular section portion of the rod allows, in an axial position, to drive the winding pinion in one direction. rotation and in the other axial position, to come into engagement with the clock train to perform the time setting.
- This member can therefore fulfill two and not three functions, so that, in the three-function mechanisms, instead of coming into direct contact with the clockwork, the sliding pinion engages a gear train designed so as to be able to alternatively connected to the clock train or to a corrector gear of the date indicator or other function derived from the time.
- the object of the present invention is to remedy, at least partially, the aforementioned drawbacks.
- the subject of the present invention is a watch with a mechanism for reassembly and correction of at least two indicator organs, as defined by claim 1.
- the winding gear successively controls two functions, the winding and the correction of the function indicator derived from the hour, so that when the sliding pinion is moved axially on the control rod it is to come into direct contact with the clockwork. Therefore, the sliding pinion of the winding mechanism, time setting and correction of another indication derived from the time, operates as a conventional sliding pinion, remaining in engagement with the winding pinion in two of the three axial positions of the control rod.
- the winding pinion instead of being in engagement with the edge teeth of the winding crown, it is simultaneously engaged with two fixed references, themselves meshing with two respective second coaxial references to two respective latches allowing, by simply moving these scales, to connect alternatively the winding stem to the winding ratchet, respectively to the corrector of the indication derived from the time. Finally, the sliding pinion moves only when moving to the time setting position, as in a conventional two-function toggle and pull-down winder.
- the sliding pinion is moved to the intermediate axial position so that its teeth are not in position. taken with neither the winding pinion nor the gear wheel.
- This arrangement makes it possible to prevent the axial locking of the control rod during the transition from the winding position to the correction position of the indication derived from the time.
- This operation causes the winding lever to move from the winding position to the unobstructed position of a sliding pinion carried by this rocker and initially engaged with the winding ratchel subjected, in a direction of rotation, to the tension of the spring barrel and locked in the other direction of rotation by a retaining pawl.
- This arrangement also makes it possible, during the displacement of the control rod in the opposite direction, to avoid causing an inadvertent correction of the indicator of a function derived from the time.
- the embodiment of the winding and correction mechanism of the watch illustrated in Figures 1 and 2 comprises a control rod 1 capable of occupying three axial positions corresponding to the control of three functions.
- This control rod 1 carries a winding pinion 2 pivoted freely on the control rod 1 and a sliding pinion 3, axially displaceable on a section of square section of the control rod 1, so that it is integral in rotation with the latter.
- the sliding pinion 3 comprises a groove 3a in which a rocker 4, biased by a spring 5, is engaged.
- the spring 5 applies this rocker 4 against a pin 6a integral with a pull rod 6 pivoted about an axis 6b of a pull screw and of which another pin 6c is engaged in a groove 1a of the control rod 1.
- This Zipper 6 further comprises a third pin 6d engaged, on the one hand, with a lever 7 for controlling a winding latch 8, on the other hand, with a jumper spring 24, ( Figure 2) determining the different axial positions. of the control rod 1.
- the rocker 8 has an arm 8a to allow the lever 7 to rotate about its pivot axis 8b in the opposite direction to that of the needles of the watch, against the torque exerted on this latch 8 by a return spring (not shown).
- the winding pinion 2 which is a conical pinion, meshes simultaneously with two references 9, 10 (FIGS. 1 and 2), one of which is situated on the side of the winding stem 1 where the winding device is located, is the movement side, while the other 10 is on the time side or dial of the watch.
- These two references 9, 10 are pivoted about fixed axes connected to the frame of the movement by support members comparable to bridges (not shown).
- the return 9 meshes with a second fixed return 11, pivoted about an axis 8b coaxial with that of the winding lever 8.
- This second gear 11 meshes with a sliding winding pinion 12, integral with the winding lever 8 and coming normally engaged with a winding ratchet 13 integral with the barrel shaft (not shown), thanks to the torque exerted by a return spring on the winding lever 8.
- the winding position is shown in the line. Continuous, while the date and time setting positions are shown in phantom.
- the reference 10 (FIG. 2) is engaged with a second reference 14 pivoted about a fixed axis, coaxial with the pivot axis 15a of a correction lever 15.
- This reference 14 meshes with a correction gear 16 intended to in this embodiment, the correction of the date and the day.
- this correction pinion 16 carries a star 16a intended to come into engagement with a date indicator ring 20.
- Another reference 21, of smaller diameter than the reference 14 is rotated coaxially with the latter and the axis of pivoting of the correction lever 15.
- This return 21 meshes with a timer wheel 22 of the time setting wheel.
- the correction lever 15 has a certain degree of freedom around its pivot axis 15a, limited by a triangular opening 15b in which a locking pin 17a of a locking lever 17 is engaged.
- This locking lever 17 is applied against the pin 6a of the pull tab 6 by a spring 18 which exerts on it a torque tending to turn it in the opposite direction to that of the needles of the watch.
- the triangular opening 15b has a side substantially perpendicular to a straight line, connecting the vertex A of this triangle opposite this side, to the pivot center 15a of the correction lever 15. It results from this arrangement that when the locking pin 17a of the locking lever 17 is placed, by the pin 6a of the pull tab 6, at the top A of the triangular opening 15b, the rocker 15 is immobilized in a position in which the pinion of correction 16 and its star 16a can not engage the date indicator ring 20 or the weekday indicator wheel 19. As can be seen, this locking of the correction lever 15 in the inactive position corresponds to the two extreme axial positions of the winding stem 1, corresponding to the winding or time setting positions respectively.
- the locking pin 17a of the locking lever 17 is positioned adjacent to the base opposite to the apex A of the triangular opening. 15b, so that the rocker 15 is then free to pivot about the pivot axis 15a in one direction or the other, in the limit fixed by the angle of displacement between the two extreme positions of the triangular opening 15b with respect to the locking pin 17a.
- One of these extreme positions corresponds to the engagement of the star 16a of the correction pinion 16 with the date ring 20.
- the other of these extreme positions corresponds to the meshing of the correction pinion 16 with the indicator wheel of the days 19.
- the passage from one position to another simply results from the direction of rotation communicated to the referral 14 by the control rod 1.
- the latch 4 in engagement with the groove 3a of the sliding pinion 3 has, like all the latches of this type, a cam shape 4a cooperating with the pin 6a of the pull tab 6, to control the axial position of the sliding pinion 3 on the rod 1, depending on the axial position of the latter.
- the cam 4a has, in its part located on the trajectory described by the pin 6a of the pull tab 6 between the winding and correction positions of the date, an elevated portion 4'a which has the effect of causing reciprocating axial displacement of the sliding pinion 3 when passing from one to the other of these two positions.
- the amplitude of this reciprocating displacement of the sliding pinion 3 is less than the stroke enabling it to come into engagement with the pinion 21, so that, during the passage from the winding position to the position of correction of the date, the pin control 1 is completely disconnected from the various wheels that it is likely to operate.
- the mechanism described retains most of the conventional two-position setting mechanism, the correction position corresponding to the third function of the control rod, being derived from that of reassembly , since it is also the winding pinion 2 which actuates this correction.
- the first referrals 9, 10, the second referrals 11, 14, the sliding pinion 12 and the correction pinion 16 are driven in both the winding position and position of correction of the date.
- the correction lever 15 is locked in the inoperative position by the locking pin 17a of the locking lever 17, so that the correction wheels 10, 14 and 16 rotate empty.
- the rocker 8 which is disengaged and it is then the mobiles of reassembly 9, 11, 12 which turn empty.
- the embodiment described above relates to a watch with indication of the date and the day.
- the variant illustrated in Figure 3 relates to a watch with indication of the date alone.
- the part of the mechanism relating to reassembly and illustrated in Figure 1, as well as that relating to the time setting remain unchanged.
- the locking lever 17 is removed and the correction lever 15 'has an arm 15'c carrying a cam 15'd cooperating with the pin 6a of the pull tab 6.
- the cam 15'd of this correction lever 15 ' is applied against the pin 6a by a spring 23.
- the variant illustrated in FIG. 4 differs from the previous one only in the shape of the correction lever 15 "whose correction pinion 16 no longer bears a correction star and can occupy, in the two respective positions defined by the rocker 15 "correction, two positions, one released, the other engaged, with a central wheel 19 'driving the indicator member (not shown).
- This central indicator member is a time zone indicator of known type, moved by jump every hour by the central wheel 19 '. This type of mechanism is known and does not form part of the invention, so it is not necessary to describe it to understand the present invention.
- the wheel 19 'meshes with a wheel 25 carrying a finger 25a for driving the date ring 20 by one pitch at each turn of the wheel 25, so that the correction of the date ring 20 is performed through the central wheel 19 'and the wheel 25.
- FIG. 5 shows a rocker 4 in which the raised portion 4'a of the cam 4a comprises a slight flat 4 * a intended to lengthen as much as possible the disengagement period between the sliding pinion 3 and the winding pinion 2 when changing from the winding position to the date correction position or vice versa.
- the inclination given to the cam 4a to connect the flat 4 * a must be chosen to allow a smooth passage, without excessive effort, from one position to another in both directions of movement of the control rod 1.
- each position of the control rod 1 corresponds to a single function, the other functions being disabled by the sole operation of the two flip-flops 8 and 15, the sliding pinion 3 being disengaged from the winding pinion 2 only in the setting position, as in a watch with the only indication hours, minutes and seconds. Except the sliding winding pinion 12 and the correction pinion 16, all the other mobiles of the mechanism have axes of fixed rotations. The number of clutches and clutches is reduced to a minimum.
- the date correction can be performed at any time, without there being a risk of locking the winding stem, or damage to the mechanism.

Description
La présente invention se rapporte à une montre à mécanisme de remontage et de correction d'au moins deux organes indicateurs, comportant une tige de commande, une tirette en prise d'une part avec cette tige de commande, d'autre part avec un ressort sautoir définissant trois positions axiales de ladite tige de commande, correspondant à celles de remontage, de correction d'au moins un organe indicateur d'une fonction dérivée de l'heure, respectivement de mise à l'heure, ladite tige de commande portant un pignon de remontoir et un pignon coulant en prise avec une bascule sollicitée par un ressort et reliée à ladite tirette pour mettre sélectivement ledit pignon coulant en prise avec ledit pignon de remontoir et avec un rouage de minuterie dans les positions extrêmes de ladite tige de commande.The present invention relates to a watch with a mechanism for winding and correcting at least two indicator members, comprising a control rod, a pull tab engaged on the one hand with this control rod, on the other hand with a spring jumper defining three axial positions of said control rod, corresponding to those of reassembly, of correction of at least one indicator member of a function derived from the time, respectively of setting time, said control rod carrying a winder pinion and a sliding pinion engaged with a spring-biased rocker and connected to said puller for selectively engaging said pinion gear in engagement with said winder pinion and with a timer train in the extreme positions of said control rod.
De tels mécanismes sont connus et utilisés dans toutes les pièces d'horlogerie mécaniques comportant un indicateur d'une fonction dérivée de l'heure, telle que les quantièmes du mois, les jours de la semaine, les phases de la lune, les différents fuseaux horaires notamment.Such mechanisms are known and used in all mechanical timepieces including an indicator of a function derived from the hour, such as the calendar of the month, the days of the week, the phases of the moon, the different time zones schedules in particular.
La commande de ces différentes fonctions nécessite le déplacement axial de la tige de commande, appelée généralement tige de remontoir, dans trois positions, la première position, c'est à dire celle où la tige de commande occupe la position poussée vers le centre du mouvement est la position habituelle de remontage, l'une des deux positions restantes est celle de la correction de la date ou fonction dérivée analogue, tandis que l'autre des positions restantes est celle de la mise à l'heure.The control of these various functions requires the axial displacement of the control rod, generally called the winding stem, in three positions, the first position, that is to say the one where the control rod is in the pushed position towards the center of the movement. is the usual winding position, one of the two remaining positions is that of the date correction or similar derivative function, while the other of the remaining positions is that of setting the time.
De façon générale, le pignon de remontoir pivoté sur la tige de commande ne sert qu'au remontage lorsqu'il est mis en prise avec le pignon coulant et ce dernier est déplacé axialement dans les deux autres positions pour venir en prise avec un renvoi connecté alternativement avec le rouage de mise à l'heure et avec le rouage de mise à la date ou de toute autre fonction dérivée. Lorsque la montre indique le quantième du mois et le jour de la semaine, on utilise généralement une bascule qui, en position de correction, peut se déplacer suivant le sens de rotation de la tige de commande, alternativement entre deux positions angulaires, pour amener le pignon correcteur en prise avec l'indicateur des quantièmes ou avec celui des jours. De tels mécanismes de corrections sont décrits par exemple, dans le GB 1'234'004, dans le FR 2'169'861 ou encore dans le CH 571'734.In general, the winding pinion pivoted on the control rod is only used for reassembly when it is engaged with the sliding pinion and the latter is moved axially in the other two positions to engage a return connected alternately with the time-setting train and with the date-setting train or any other derived function. When the watch indicates the day of the month and the day of the week, it is generally used a rocker which, in the correction position, can move in the direction of rotation of the control rod, alternately between two angular positions, to bring the corrective gear engaged with the date indicator or with that of the days. Such correction mechanisms are described, for example, in GB 1'234'004, in FR 2'169'861 or else in CH 571'734.
L'un des problèmes posés par la commande de trois fonctions vient du fait que le pignon de remontoir n'est utilisé que pour le remontage, de sorte que le pignon coulant doit commander deux fonctions. Or, le pignon coulant, avec ses deux dentures en bout, est l'organe qui, en étant déplacé axialement sur une portion de section non circulaire de la tige permet, dans une position axiale, d'entraîner le pignon de remontoir dans un sens de rotation et dans l'autre position axiale, de venir en prise avec le rouage de minuterie pour effectuer la mise à l'heure. Cet organe peut donc remplir deux et non trois fonctions, de sorte que, dans les mécanismes à trois fonctions, au lieu de venir directement en prise avec le rouage de minuterie, le pignon coulant vient en prise avec un rouage conçu de manière à pouvoir être connecté alternativement au rouage de minuterie ou à un rouage correcteur de l'indicateur de quantième ou autre fonction dérivée de l'heure.One of the problems with the control of three functions is that the winding pinion is used only for reassembly, so that the sliding pinion must control two functions. However, the sliding pinion, with its two end teeth, is the member which, being moved axially on a non-circular section portion of the rod allows, in an axial position, to drive the winding pinion in one direction. rotation and in the other axial position, to come into engagement with the clock train to perform the time setting. This member can therefore fulfill two and not three functions, so that, in the three-function mechanisms, instead of coming into direct contact with the clockwork, the sliding pinion engages a gear train designed so as to be able to alternatively connected to the clock train or to a corrector gear of the date indicator or other function derived from the time.
Pour passer d'une fonction de correction à l'autre dans ces mécanismes à trois fonctions, il faut donc recourir à des dispositifs plus ou moins complexes utilisant des systèmes à renvois, pignons baladeurs et débrayages multiples, pouvant poser des problèmes de pénétration des dentures les unes dans les autres et donc des problèmes d'usure et d'arc-boutement.To switch from one correction function to another in these three-function mechanisms, it is therefore necessary to resort to more or less complex devices using return systems, sliding gears and multiple clutches, which can cause problems of tooth penetration the in each other and therefore problems of wear and bracing.
Un des problèmes que l'on rencontre dans ces mécanismes est celui du blocage axial de la tige de commande lorsque l'on passe d'une position à une autre, en cas de dysfonctionnement du correcteur lors du changement de position axiale, blocage provoqué par le mode de commande du correcteur. Un autre problème est celui de corrections intempestives, induites lors du passage d'une position axiale de la tige de commande à une autre.One of the problems encountered in these mechanisms is that of the axial locking of the control rod when moving from one position to another, in case of malfunction of the corrector during the change of axial position, blocking caused by the control mode of the corrector. Another problem is that of untimely corrections, induced during the passage of an axial position of the control rod to another.
Le but de la présente invention est de remédier, au moins partiellement, aux inconvénients susmentionnés.The object of the present invention is to remedy, at least partially, the aforementioned drawbacks.
A cet effet, la présente invention a pour objet une montre à mécanisme de remontage et de correction d'au moins deux organes indicateurs, telle que définie par la revendication 1.For this purpose, the subject of the present invention is a watch with a mechanism for reassembly and correction of at least two indicator organs, as defined by
Contrairement aux mécanismes de l'art antérieur, le pignon de remontoir commande successivement deux fonctions, le remontage et la correction de l'indicateur de fonction dérivée de l'heure, de sorte que lorsque le pignon coulant est déplacé axialement sur la tige de commande, c'est pour venir directement en prise avec le rouage de minuterie. Par conséquent, le pignon coulant du mécanisme de remontage, de mise à l'heure et de correction d'une autre indication dérivée de l'heure, fonctionne comme un pignon coulant classique, restant en prise avec le pignon de remontoir dans deux des trois positions axiales de la tige de commande.Unlike the mechanisms of the prior art, the winding gear successively controls two functions, the winding and the correction of the function indicator derived from the hour, so that when the sliding pinion is moved axially on the control rod it is to come into direct contact with the clockwork. Therefore, the sliding pinion of the winding mechanism, time setting and correction of another indication derived from the time, operates as a conventional sliding pinion, remaining in engagement with the winding pinion in two of the three axial positions of the control rod.
Quant au pignon de remontoir, au lieu d'être en prise avec la denture de chant de la couronne de remontage, il est simultanément en prise avec deux renvois fixes, eux-mêmes engrenant avec deux seconds renvois respectifs coaxiaux à deux bascules respectives permettant, par simple déplacement de ces bascules, de relier alternativement la tige de remontoir au rochet de remontoir, respectivement au correcteur de l'indication dérivée de l'heure. Enfin, le pignon coulant se déplace uniquement lors du passage à la position de mise à l'heure, comme dans un remontoir à bascule et tirette classique à deux fonctions.As for the winding pinion, instead of being in engagement with the edge teeth of the winding crown, it is simultaneously engaged with two fixed references, themselves meshing with two respective second coaxial references to two respective latches allowing, by simply moving these scales, to connect alternatively the winding stem to the winding ratchet, respectively to the corrector of the indication derived from the time. Finally, the sliding pinion moves only when moving to the time setting position, as in a conventional two-function toggle and pull-down winder.
Avantageusement, pour éviter un blocage de la tige de commande lors du passage de la position de remontage à la position de correction de l'indication dérivée de l'heure, le pignon coulant est déplacé en position axiale intermédiaire afin que ses dentures ne soient en prise ni avec le pignon de remontoir ni avec le rouage de minuterie.Advantageously, to prevent the control rod from being blocked during the passage from the winding position to the correction position of the indication derived from the hour, the sliding pinion is moved to the intermediate axial position so that its teeth are not in position. taken with neither the winding pinion nor the gear wheel.
Cette disposition permet d'éviter le blocage axial de la tige de commande lors du passage de la position de remontage à la position de correction de l'indication dérivée de l'heure. Cette opération provoque le déplacement de la bascule de remontoir de la position de remontage à la position dégagée d'un pignon baladeur porté par cette bascule et initialement en prise avec le rochet de remontoir soumis, dans un sens de rotation, à la tension du ressort de barillet et bloqué dans l'autre sens de rotation par un cliquet de retenue. Cette disposition permet également, lors du déplacement de la tige de commande en sens inverse, d'éviter de provoquer une correction intempestive de l'indicateur d'une fonction dérivée de l'heure.This arrangement makes it possible to prevent the axial locking of the control rod during the transition from the winding position to the correction position of the indication derived from the time. This operation causes the winding lever to move from the winding position to the unobstructed position of a sliding pinion carried by this rocker and initially engaged with the winding ratchel subjected, in a direction of rotation, to the tension of the spring barrel and locked in the other direction of rotation by a retaining pawl. This arrangement also makes it possible, during the displacement of the control rod in the opposite direction, to avoid causing an inadvertent correction of the indicator of a function derived from the time.

A cet effet, outre sa denture susceptible de venir en prise avec une roue 19 solidaire de l'indicateur des jours de la semaine, ce pignon de correction 16 porte une étoile 16a destinée à venir en prise avec un anneau 20 indicateur de quantièmes.The reference 10 (FIG. 2) is engaged with a
Un autre renvoi 21, de plus petit diamètre que le renvoi 14 est pivoté coaxialement à ce dernier et à l'axe de pivotement de la bascule de correction 15. Ce renvoi 21 engrène avec une roue de minuterie 22 du rouage de mise à l'heure.Another
La bascule de correction 15 présente un certain degré de liberté autour de son axe de pivotement 15a, limité par une ouverture triangulaire 15b dans laquelle une cheville de verrouillage 17a d'un levier de verrouillage 17 est engagée. Ce levier de verrouillage 17 est appliqué contre la cheville 6a de la tirette 6 par un ressort 18 qui exerce sur lui un couple tendant à le faire tourner dans le sens contraire de celui des aiguilles de la montre.The
Comme on le voit sur la figure 2, l'ouverture triangulaire 15b présente un côté sensiblement perpendiculaire à une droite, reliant le sommet A de ce triangle opposé à ce côté, au centre de pivotement 15a de la bascule de correction 15. Il résulte de cette disposition que lorsque la cheville de verrouillage 17a du levier de verrouillage 17 se trouve placée, par la cheville 6a de la tirette 6, au sommet A de l'ouverture triangulaire 15b, la bascule 15 est immobilisée dans une position dans laquelle le pignon de correction 16 et son étoile 16a ne peuvent venir en prise ni avec l'anneau 20 indicateur des quantièmes ni avec la roue 19 indicatrice des jours de la semaine. Comme on le voit, ce verrouillage de la bascule de correction 15 en position inactive correspond aux deux positions axiales extrêmes de la tige de remontoir 1, correspondant aux positions de remontage, respectivement de mise à l'heure.As can be seen in FIG. 2, the
Dans la position illustrée en trait continu sur la figure 2 et qui correspond à la position de correction du quantième et du jour, la cheville de verrouillage 17a du levier de verrouillage 17 est positionnée adjacente à la base opposée au sommet A de l'ouverture triangulaire 15b, de sorte que la bascule 15 est alors libre de pivoter autour de l'axe de pivotement 15a dans un sens ou dans l'autre, dans la limite fixée par l'angle de déplacement entre les deux positions extrêmes de l'ouverture triangulaire 15b par rapport à la cheville de verrouillage 17a.In the position shown in solid lines in FIG. 2 and corresponding to the date and date correction position, the
Une de ces positions extrêmes, représentée en trait continu, correspond à la mise en prise de l'étoile 16a du pignon correcteur 16 avec l'anneau des quantièmes 20. L'autre de ces positions extrêmes correspond à l'engrènement du pignon correcteur 16 avec la roue indicatrice des jours 19. Le passage d'une position à l'autre résulte simplement du sens de rotation communiqué au renvoi 14 par la tige de commande 1.One of these extreme positions, shown in solid lines, corresponds to the engagement of the
La bascule 4 en prise avec la gorge 3a du pignon coulant 3 présente, comme toutes les bascules de ce type, une forme de came 4a coopérant avec la cheville 6a de la tirette 6, pour commander la position axiale du pignon coulant 3 sur la tige de commande 1, en fonction de la position axiale de cette dernière. A la différence des bascules classiques de ce type, la came 4a comporte, dans sa partie située sur la trajectoire décrite par la cheville 6a de la tirette 6 entre les positions de remontage et de correction de la date, une portion surélevée 4'a qui a pour effet de provoquer un déplacement axial alternatif du pignon coulant 3 lors du passage de l'une à l'autre de ces deux positions. L'amplitude de ce déplacement alternatif du pignon coulant 3 est inférieure à la course lui permettant de venir en prise avec le renvoi 21, de sorte que, lors du passage de la position de remontage à la position de correction de la date, la tige de commande 1 est complètement déconnectée des différents rouages qu'elle est susceptible d'actionner.The
Grâce à cette disposition, en passant de la position de remontage à celle de correction de la date, la tige de commande 1 ne peut pas être bloquée lors du dégagement du pignon baladeur 12 du rochet 13 (figure 1), étant donné que le pignon de remontoir 2 est débrayé de cette tige de commande 1 au cours de cette opération. Pour la même raison, lors du passage de la position de correction de la date à celle de remontage, un déplacement intempestif d'un organe indicateur de la date ne risque pas de se produire.With this arrangement, by switching from the winding position to that of the date correction, the
Quant au passage de la position de correction de la date à celle de mise à l'heure, correspondant à la position axiale où la tige de commande 1 est dans sa position extérieure extrême, étant donné qu'il provoque le déplacement axial du pignon coulant 3 pour le mettre en prise avec le renvoi 21 du rouage de minuterie, le pignon de remontoir 2 commandant les deux autres fonctions se trouve donc débrayé de la tige de commande 1, dès le début de cette opération. Ainsi, aucun déplacement intempestif ni blocage n'est susceptible de se produire.As for the transition from the position of correction of the date to that of setting time, corresponding to the axial position where the
Comme on peut s'en rendre compte, le mécanisme décrit conserve l'essentiel du mécanisme de mise à l'heure classique à deux positions, la position de correction correspondant à la troisième fonction de la tige de commande, étant dérivée de celle de remontage, puisque c'est aussi le pignon de remontoir 2 qui actionne cette correction. Les premiers renvois 9, 10, les seconds renvois 11, 14, le pignon baladeur 12 et le pignon de correction 16 sont entraînés aussi bien en position de remontage qu'en position de correction de la date. En position de remontage, la bascule de correction 15 est bloquée en position inopérante par la cheville de verrouillage 17a du levier de verrouillage 17, de sorte que les mobiles de correction 10, 14 et 16 tournent à vide. En position de correction de la date, c'est la bascule 8 qui est débrayée et ce sont alors les mobiles de remontage 9, 11, 12 qui tournent à vide.As can be appreciated, the mechanism described retains most of the conventional two-position setting mechanism, the correction position corresponding to the third function of the control rod, being derived from that of reassembly , since it is also the winding
La forme d'exécution décrite ci-dessus se rapporte à une montre avec indication du quantième et du jour. La variante illustrée par la figure 3 se rapporte à une montre avec indication du quantième seul. La partie du mécanisme relative au remontage et illustrée par la figure 1, ainsi que celle relative à la mise à l'heure restent inchangées. Dans la partie du mécanisme relative à la correction du quantième, le levier de verrouillage 17 est supprimé et la bascule de correction 15' comporte un bras 15'c porteur d'une came 15'd coopérant avec la cheville 6a de la tirette 6. La came 15'd de cette bascule de correction 15' est appliquée contre la cheville 6a par un ressort 23.The embodiment described above relates to a watch with indication of the date and the day. The variant illustrated in Figure 3 relates to a watch with indication of the date alone. The part of the mechanism relating to reassembly and illustrated in Figure 1, as well as that relating to the time setting remain unchanged. In the part of the mechanism relating to the correction of the date, the locking
La différence entre cette bascule de correction 15' et celle de la forme d'exécution de la figure 2 réside dans le fait que la bascule 15' n'est jamais libre ou verrouillée, comme l'est la bascule 15, mais qu'elle suit constamment la position définie par la came 15'd, appliquée contre la cheville 6a de la tirette 6 par le ressort de rappel 23. Comme on peut le constater sur cette figure 3, l'étoile 16a portée par le pignon de correction 16 est en prise avec l'anneau de quantièmes 20 dans la position illustrée en trait continu sur la figure 3, c'est à dire dans la position de correction du quantième, tandis qu'elle est débrayée de l'anneau de quantième 20 dans les deux autre positions correspondant aux positions extrêmes de la tige de commande 1.The difference between this correction flip-flop 15 'and that of the embodiment of FIG. 2 lies in the fact that flip-flop 15' is never free or locked, as is flip-
La variante illustrée par la figure 4 ne diffère de la précédente que par la forme de la bascule de correction 15" dont le pignon de correction 16 ne porte plus d'étoile de correction et peut occuper, dans les deux positions respectives définies par la bascule de correction 15", deux positions, l'une dégagée, l'autre engagée, avec une roue centrale 19' entraînant l'organe indicateur (non représenté). Cet organe indicateur central constitue un indicateur de fuseau horaire de type connu, déplacé par saut à chaque heure par la roue centrale 19'. Ce type de mécanisme est connu et ne fait pas partie de l'invention, de sorte qu'il n'est pas nécessaire de le décrire pour comprendre la présente invention.The variant illustrated in FIG. 4 differs from the previous one only in the shape of the
La roue 19' engrène avec une roue 25 porteuse d'un doigt 25a destiné à entraîner l'anneau de quantième 20 d'un pas à chaque tour de la roue 25, de sorte que la correction de l'anneau de quantièmes 20 est effectuée à travers la roue centrale 19' et la roue 25.The wheel 19 'meshes with a
La variante illustrée par la figure 5 représente une bascule 4 dans laquelle la partie surélevée 4'a de la came 4a comporte un léger plat 4*a destiné à allonger le plus possible la période de débrayage entre le pignon coulant 3 et le pignon de remontoir 2 lors du passage de la position de remontage à la position de correction de la date ou inversement. Bien entendu, l'inclinaison donnée à la came 4a pour relier le plat 4*a doit être choisie pour permettre un passage doux, sans effort excessif, d'une position à l'autre dans les deux sens de déplacement de la tige de commande 1.The variant illustrated in FIG. 5 shows a
Comme on a pu s'en rendre compte au cours de la description qui précède, avec le mécanisme de remontage et de correction d'au moins deux indicateurs selon la présente invention, chaque position de la tige de commande 1 correspond à une fonction unique, les autres fonctions étant mises hors service par le seul actionnement des deux bascules 8 et 15, le pignon coulant 3 n'étant débrayé du pignon de remontoir 2 qu'en position de mise à l'heure, comme dans une montre avec la seule indication des heures, minutes et secondes. Excepté le pignon baladeur de remontage 12 et le pignon de correction 16, tous les autres mobiles du mécanismes ont des axes de rotations fixes. Le nombre des débrayages et embrayages est réduit à un minimum.As can be appreciated from the preceding description, with the mechanism for reassembly and correction of at least two indicators according to the present invention, each position of the
Grâce à la bascule de correction 15, la correction de la date peut être réalisée à n'importe quel moment, sans qu'il y ait risque de blocage de la tige de remontoir, ou d'endommagement du mécanisme.With the
L'utilisation d'un pignon conique comme pignon de remontoir 2 permet à celui-ci d'engrener directement avec les deux pignons 9 et 10 des rouages de remontage, respectivement de correction, sans avoir besoin de roues à dentures de chant.The use of a bevel gear as a winding
