Definitions
- the present invention relates to a correction device for modifying the data of a plurality N of time functions displayed by a timepiece.
- a crown rod which can be placed in the first and second drawn positions for selecting the date and the time setting is used in most timepieces, the correction being effected by the rotation of the crown.
- the advantage of this system lies in the bidirectional correction of the data to be modified but limits the choice to two functions that can be corrected. If other functions, for example the day of the week and the month must be corrected, we could add on the middle of the timepiece a second stem crown with the technical complications and the lack of aesthetics that this solution lead.
- the corrections to be made may also be implemented by push buttons, each of which corrects a displayed time data. Often, these pushers are correctors embedded in the middle part, which does not affect the aesthetics of the whole. On the other hand, the main disadvantage of this solution lies in its unidirectional operation to which will be added the possible breakage of the mechanism if two pushers are activated at the same time.
- the watchmaker therefore feels the need to design a system that combines pusher and stem-crown, the pusher allowing the choice of the function among several available and the stem-crown allowing correction in both directions of the chosen function.
- a draft of the system mentioned above is proposed in the patent application CH 700 531 A2 .
- a function change button and a correction rod of the selected function this rod being rotated by a serrated ring manually movable around the middle part of the timepiece.
- the pusher allows each punctual support (that is to say a support followed by a loosening) to change the function to be corrected by the ring.
- a first one-time press selects the time-setting function
- a second one-time press selects the date-setting function
- a third one-time press will again select the winding function.
- the presented system provides a display device of the function filled by the ring during rotation. This system is reminiscent of the control of a classic watch since it uses, mounted on the stem, a sliding pinion. It will be understood therefore that the number of functions displayed by the watch is limited to two units, namely setting the time and date.
- the general principle of the present invention is shown in figure 1 .
- the timepiece is equipped with a correction device for modifying the data of a plurality N of time functions displayed by said timepiece.
- the invention is remarkable in that the device comprises on the one hand a pushbutton 1 of change of function whose actuation, that is to say a support followed by a release of said pusher 1, moves a control wheel 2.
- the timepiece having a plurality N of time functions, each of these is equipped with a correction gear of the selected function referenced respectively 3, 4, 5 or 6 on the figure 1 .
- These correction gears are linked to the function with a view to its correction by a mechanism not described here but adapted to correct the function chosen, for example the date, the day of the week, the month, the time setting or the moon phase.
- the device of the invention further comprises a rod 7 capped with a ring 8 whose rotation in one direction or the other rotates the control wheel 2 which in turn drives one of the correct gears 3 , 4, 5 or 6 to correct more or less the data of the selected function.
- a rod not provided with axial displacement the reassembly being provided by an oscillating mass and setting time by the device of the present invention.
- the rod 7 can assume three axial positions, a the so-called "walking" position in which manual winding of the timepiece is possible, a first pulled position T2 allowing the correction of the data of the time function chosen according to the present invention, and a second drawn position T3 allowing the setting time of the timepiece by known means.
- the figure 1 shows that the actuation of the pusher 1 travels to the axis 19 that has the control wheel 2 a circular path.
- each of the correcting pinions 3, 4, 5, 6 is arranged around said trajectory, the pitch radius of each of said correction gears being sized to mesh with the pitch radius of the control wheel 2.
- the correction pinion 6 is not represented in figure 1 not to complicate said figure. This pinion 6 however appears in figure 10 which allows this representation.
- the device of the invention is designed such that, when the pusher 1 is actuated, the control wheel 2 simultaneously moves its axis 19 in accordance with a circular path, rotates on itself so as not to cause the function correction pinion (3, 4, 5, 6) with which it has engaged.
- this second intermediate return 41 is mounted on a disengaging arm 42 pivoting around the first shaft 17 on which the first and second sets freely rotate.
- the disengaging arm 42 is controlled by a control lever 50 recalled by a third spring 51, this latch 50 being controlled itself by the system of levers 11 and 35 actuated by the pusher 1.
- the star 14 has not a number N of teeth 30 but a number N + 1 of teeth 30, this to provide an additional so-called rest function in which the control wheel 2 is engaged with no correction gear.
- the star 14 is provided with five teeth 30 arranged at 72 ° to each other, the correction gears being reduced to the number of four always arranged at 72 ° from each other.
- the first set composed of the star 14 and the star wheel 16 carries a disk 48 in which are written the various functions 49 that can be corrected, the function 53 that can be corrected appearing in a window 52 pierced in the dial 55 that carries the timepiece.
- the second intermediate return 41 is kinematically connected to the rod 7 by a gear train comprising the mobiles 47, 43, 44, 45 and 46, the rod 7 being in the first drawn position T2. More particularly, this gear train has a sliding pinion 60 sliding on the rod 7, sliding pinion 60 and rod 7 being connected by a drawbar system 61 and latch 62 known from the state of the art.
- the rod 7 When the rod 7 is rotated, it causes a first return 43 which in turn causes a second return 44 which is engaged with a return wheel 45 actuating a platinum-plate return 46, the latter meshing finally with the second return intermediate 41.
- the figure 3 presents the situation of the sponsorship defined with regard to figure 2 in the case where the rod 7 is in the pushed position T1.
- any connection of the sliding pinion 47 with the rest of the gear train is interrupted, the sliding pinion causing the unrepresented winding of the barrel of the timepiece.
- the control wheel 2 can be oriented towards any function.
- the figure 4 presents the situation of the mechanism defined for the figure 2 in the case where the rod 7 is in the second drawn position T3.
- the sliding pinion 47 is engaged with the first return 43 which in turn causes the time setting mechanism not shown.
- the connection of the first reference 43 with the second reference 44 is interrupted.
- the control wheel 2 can be directed towards any function.
- the figure 5 is a plan view of a first stage of function change.
- a beginning of pressing on the pusher 1 makes contact the spout 13 of the lever system 11, 35 with a tooth 30 of the star 14.
- the star 14 is still immobile.
- the lever system 11, 35 acts on the control latch 50 which pivots the disengaging arm 42 and the second intermediate link 41 which is connected thereto.
- This second return 41 then leaves the last mobile 46 of the gear train which links it to the rod 7 to mesh with the main return wheel 20.
- the axis 19 of the control wheel 2 connected to the wheel of 'star 16 is likely to move in a circular trajectory at the same time as it turns on itself by virtue of its meshing with the central pinion 18.
- the figure 6 is a plan view of a second stage of change of function where the pusher 1 continues to be activated and the figure 7 is a section along the line BB of the figure 6 .
- the spout 13 drives the star 14 by a flank of its tooth 30, then the star wheel 16 which is linked to it, the latter driving in a circular path the axis 19 of the control wheel 2 which is is about halfway between two corrective gears 4 and 3.
- the figure 8 is a plan view of a third stage of change of function where the pusher is towards the end of its activation.
- the control wheel is close to the complete meshing with the new correction gear 3, the complete meshing taking place at the moment of release of the pusher 1.
- the jumper 22 blocks the star between two of its teeth and the second intermediate return 41, by the action of the release arm 42, left the main return wheel 20 to mesh again with the last mobile 46 of the train of gearing that binds it to the rod 7. From this moment, the driving of the wheel of the control 2 and the new correction pinion 3 is done by the rotation of the rod 7.
- the figure 9 is a sectional view of the mechanism being changed function, the control wheel 2 located between two gears of function 4 and 3. At this time the last mobile 46 of the gear train controlled by the rod 7 is meshes more with the second intermediate referral 41, the latter mobile 46 rotating empty, even if, inadvertently, the rod 7 is rotated during a function change operation performed by the pusher.
- the figure 10 is a schematic view of the drive train taken into account when the pushbutton 1 is activated. From this moment the star 14 (not shown) rotates the star wheel 16 in the direction of the arrow 60. The axis 19 of the control wheel 2 fixed to the star wheel 16 progresses in the direction of the arrow 61 in a circular path as seen above. The control wheel 2 passes from the correction gear 4 to the correction gear 3 during the pushing and release of the pusher 1. Simultaneously with this movement, the control wheel 2 will turn on itself in the direction of the arrow 70 in such a way that its rotation leaves still first the corrector pinion 4 it leaves then the 3 with which it engages. This precaution is essential because without it the functions displayed would be totally out of order.
- the control wheel 2 must rotate in a direction 70 opposite to that 60 of the star wheel 16 which is the same as that of the direction of rotation 61 of the axis 19 of the wheel 2.
- the rotation and the direction of rotation of the control wheel 2 are governed in the order and from the star wheel 16 which rotates in the direction of the arrow 60, by the following mobiles driven by said star wheel 16: the first intermediate gear 40 (direction of the arrow 62), the main gear 21 (arrow 63), the main gear 20 (arrow 64), the second intermediate gear 41 (arrow 65) , the central wheel 24 (arrow 66), the central gear 18 (arrow 67) and the control wheel 2 (arrow 70).
- the rotation of the rod 7 drives the gear train 47, 43, 44, 45, 46, the last mobile, the platinum-plate return 46, finally meshes with the central wheel 24 via the second intermediate return 41.
- the central wheel 24 drives the central pinion 18 which is attached to it coaxially, this central pinion 18 in turn driving the control wheel 2 which finally causes in one direction or the other, in the direction of rotation printed on the ring 8 styling the rod 7, the new function correction gear 3.
- the second intermediate gear 41 and consequently the first intermediate gear 40, could be removed, if the third set consisted of a main gear 20 mounted frictionally on the main gear 21, the pinion 21 meshing directly with the star wheel 16 and the wheel 20 meshing with both the second assembly consisting of the central wheel 24 and the central gear 18 and with the gear train connected with the rod 7, this train having a radial disengagement means controlled by the pusher during its activation.

Description
La présente invention est relative à un dispositif de correction permettant de modifier les données d'une pluralité N de fonctions temporelles affichées par une pièce d'horlogerie.The present invention relates to a correction device for modifying the data of a plurality N of time functions displayed by a timepiece.
Pour réaliser ces corrections on met en oeuvre dans la plupart des pièces d'horlogerie une tige-couronne qui peut être placée dans des première et seconde positions tirées pour sélectionner respectivement le quantième et la mise à l'heure, la correction s'effectuant par la rotation de la couronne. L'avantage de ce système se trouve dans la correction bidirectionnelle de la donnée à modifier mais limite le choix à deux fonctions pouvant être corrigées. Si d'autres fonctions, par exemple le jour de la semaine et le mois doivent être corrigées, on pourrait ajouter sur la carrure de la pièce d'horlogerie une seconde tige-couronne avec les complications techniques et le manque d'esthétisme que cette solution amènerait.In order to carry out these corrections, a crown rod which can be placed in the first and second drawn positions for selecting the date and the time setting is used in most timepieces, the correction being effected by the rotation of the crown. The advantage of this system lies in the bidirectional correction of the data to be modified but limits the choice to two functions that can be corrected. If other functions, for example the day of the week and the month must be corrected, we could add on the middle of the timepiece a second stem crown with the technical complications and the lack of aesthetics that this solution lead.
Les corrections à réaliser peuvent être également mises en oeuvre par des poussoirs, chacun de ceux-ci corrigeant une donnée temporelle affichée. Souvent, ces poussoirs sont des correcteurs noyés dans la carrure, ce qui ne nuit pas à l'esthétisme de l'ensemble. Par contre, l'inconvénient principal de cette solution se trouve dans son fonctionnement unidirectionnel auquel on ajoutera le bris possible du mécanisme si deux poussoirs sont activés en même temps.The corrections to be made may also be implemented by push buttons, each of which corrects a displayed time data. Often, these pushers are correctors embedded in the middle part, which does not affect the aesthetics of the whole. On the other hand, the main disadvantage of this solution lies in its unidirectional operation to which will be added the possible breakage of the mechanism if two pushers are activated at the same time.
L'horloger ressent donc le besoin de concevoir un système qui associe poussoir et tige-couronne, le poussoir permettant le choix de la fonction parmi plusieurs à disposition et la tige-couronne permettant la correction dans les deux sens de la fonction choisie.The watchmaker therefore feels the need to design a system that combines pusher and stem-crown, the pusher allowing the choice of the function among several available and the stem-crown allowing correction in both directions of the chosen function.
Une ébauche du système évoqué ci-dessus est proposée dans la demande de brevet
S'il s'agit donc de mettre en place un système de correction apte à corriger dans les deux sens plus de deux données temporelles affichées par la pièce d'horlogerie, mais en gardant l'idée d'un poussoir pour sélectionner la donnée affichée et d'une tige pour corriger ladite donnée, une voie différente de celle du pignon coulant devra être trouvée, cette voie étant celle proposée par la présente invention qui est remarquable en ce qu'elle comporte un poussoir de changement de fonction dont l'actionnement déplace une roue de commande pour l'amener en prise avec un pignon correcteur de la fonction choisie, et une tige coiffée d'une couronne dont la rotation dans un sens ou dans l'autre fait pivoter ladite roue de commande qui entraîne à son tour l'un desdits pignons correcteurs pour corriger en plus ou en moins les données de ladite fonction choisie.If it is therefore to set up a correction system capable of correcting in both directions more than two time data displayed by the timepiece, but keeping the idea of a push to select the displayed data and a rod for correcting said datum, a path different from that of the sliding pinion will have to be found, this path being that proposed by the present invention which is remarkable in that it comprises a function change pushbutton whose actuation moves a control wheel to bring it into engagement with a correcting gear of the selected function, and a crown rod with a rotation in one direction or the other rotates said control wheel which in turn drives one of said correction gears for correcting more or less the data of said selected function.

De plus, dans la version préférée décrite au paragraphe ci-dessus, le dispositif de l'invention est réalisé de telle façon que lors de l'actionnement du poussoir 1, la roue de commande 2, simultanément au déplacement de son axe 19 selon une trajectoire circulaire, tourne sur elle-même de façon à ne pas entrainer le pignon correcteur de fonction (3, 4, 5, 6) avec lequel elle s'est placée en prise.In addition, in the preferred version described in the above paragraph, the device of the invention is designed such that, when the pusher 1 is actuated, the
On va décrire maintenant dans le détail de quoi est composé le dispositif de l'invention exécuté selon la version préférée évoquée ci-dessus, et selon la version plus élaborée où la tige 7 peut être disposée sur trois postions axiales différentes. Pour cela on se référera principalement à la
- un système de leviers composé de deux
éléments 11 et 35 et rappelé par unpremier ressort 15. Ce système est équipé d'untalon 12 sur lequel s'appuie le poussoir de changement de fonction 1 et d'unbec 13. Cebec 13 est arrangé pour actionner lesdents 30 d'uneétoile 14. L'étoile 14 présente un nombre N dedents 30 égal au nombre de fonctions temporelles à corriger. Entre deuxdents 30 de l'étoile 14 prend place unsautoir 22 quand le système delevier 11 et 35 n'est pas activé par le poussoir 1. Lesautoir 22 est rappelé par unsecond ressort 23, - une roue d'étoile 16 fixée coaxialement à l'étoile 14 pour former un premier ensemble qui tourne librement sur un
premier arbre 17. Autour de cepremier arbre 17 tourne librement un deuxième ensemble formé d'une roue centrale 24 sur laquelle est fixé coaxialement un pignon central 18, - un
second arbre 19 fixé excentriquement sur la roue d'étoile 16 pour servir d'axe de rotation autour duquel tourne librement la roue decommande 2. La roue decommande 2 engrène, à la manière d'un satellite, sur le pignon central 18. Ladite roue decommande 2 est en prise avec l'un desdits pignons correcteurs de 3, 4, 5, 6, ici avec lefonction pignon correcteur 4, - un troisième ensemble formé d'une roue de renvoi principal 20 sur laquelle est fixé coaxialement un pignon de renvoi principal 21. Le pignon de renvoi principal 21 engrène avec la roue d'étoile 16 par l'entremise d'un premier renvoi intermédiaire 40, et
- un
second renvoi intermédiaire 41 engrenant en permanence avec la roue centrale 24. Cesecond renvoi intermédiaire 41 est susceptible d'être entraîné soit par la roue de renvoiprincipal 20 comme montré enfigure 7 , soit par un dernier mobile 46 d'un train d'engranges 47, 43, 44, 45, 46 commandé par la tige 7, comme montré enfigures 1 et 2 .
- a system of levers composed of two
11 and 35 and recalled by aelements first spring 15. This system is equipped with aheel 12 on which rests the change of function pusher 1 and aspout 13. Thisspout 13 is arranged to actuate theteeth 30 of astar 14. Thestar 14 has a number N ofteeth 30 equal to the number of temporal functions to be corrected. Between twoteeth 30 of thestar 14 takes place ajumper 22 when the 11 and 35 is not activated by the pusher 1. Thelever system jumper 22 is recalled by asecond spring 23, - a
star wheel 16 fixed coaxially with thestar 14 to form a first assembly which freely rotates on afirst shaft 17. Around thisfirst shaft 17 freely rotates a second assembly formed of acentral wheel 24 on which is fixed coaxially acentral gear 18, - a
second shaft 19 eccentrically fixed to thestar wheel 16 to serve as an axis of rotation around which thecontrol wheel 2 rotates freely. Thecontrol wheel 2 meshes, in the manner of a satellite, with thecentral pinion 18Said control wheel 2 is engaged with one of said 3, 4, 5, 6, here with thefunction correcting gears correction pinion 4, - a third assembly formed by a
main return wheel 20 on which is fixed coaxially amain gear 21. Themain gear 21 meshes with thestar wheel 16 via a firstintermediate gear 40, and - a second
intermediate gear 41 meshing permanently with thecentral wheel 24. This secondintermediate gear 41 can be driven either by themain gear wheel 20 as shown in FIG.figure 7 or by a last mobile 46 of a 47, 43, 44, 45, 46 controlled by thegear train rod 7, as shown in FIG.figures 1 and2 .
Pour rendre possible l'engrènement du second renvoi intermédiaire 41 soit sur la roue de renvoi principal 20, soit sur le dernier mobile 46 commandé par la tige 7, ce second renvoi intermédiaire 41 est monté sur un bras de débrayage 42 pivotant autour du premier arbre 17 sur lequel tournent librement les premier et deuxième ensembles. Le bras de débrayage 42 est commandé par une bascule de contrôle 50 rappelée par un troisième ressort 51, cette bascule 50 étant commandée elle-même par le système de leviers 11 et 35 actionné par le poussoir 1.To make possible the meshing of the second
Dans le cas particulier montré dans les figures, l'étoile 14 présente non pas un nombre N de dents 30 mais un nombre N+1 de dents 30, ceci pour ménager une fonction supplémentaire dite de repos dans laquelle la roue de commande 2 n'est en prise avec aucun pignon correcteur. Ainsi dans le cas présenté l'étoile 14 est pourvue de cinq dents 30 disposées à 72° l'une de l'autre, les pignons correcteurs étant réduits au nombre de quatre toujours disposés à 72° l'un de l'autre.In the particular case shown in the figures, the

Il a été expliqué plus haut le rôle important joué par le second renvoi intermédiaire 41 engrenant d'une part en permanence à la manière d'un satellite avec la roue centrale 24 et d'autre part soit avec la roue de renvoi principal 20 quand le poussoir 1 est activé pour procéder à un changement de fonction, soit avec le dernière mobile 46 du train d'engrenages aboutissant à la tige pour procéder à une correction de la fonction choisie.It has been explained above the important role played by the second

Le sens de rotation 70 de la roue de commande 2 étant opposé au sens de rotation 60 de la roue d'étoile, il s'agit maintenant de dimensionner les rayons primitifs des mobiles, constituant la chaîne cinématique mentionnée plus haut pour que le déplacement angulaire de la roue de commande 2 soit tel qu'il laisse immobile le pignon correcteur (3, 4) qu'elle quitte ou avec lequel elle se met en prise. Des développements mathématiques ont permis d'établir deux équations qui, si elle sont satisfaites, permettent d'assurer le résultat recherché, soit

On constate que les rayons primitifs des pignons correcteurs (3 à 6) ainsi que les rayons des premier et second renvois intermédiaires n'apparaissent pas dans ces équations et sont donc libres du choix. De plus la tabelle ci-dessous donne un exemple de réalisation pratique :
Dès l'instant où le poussoir 1 est relâché, l'entrainement de la roue de commande 2 se fait par la rotation de la tige 7 qui est en mesure de corriger en plus ou en moins les données affichées par la fonction temporelle choisie par le poussoir 1. Cette situation est la même que cette montrée en
La rotation de la tige 7 entraîne le train d'engrenage 47, 43, 44, 45, 46 dont le dernier mobile, le renvoi platine-planche 46, engrène finalement avec la roue centrale 24 par l'entremise du second renvoi intermédiaire 41. La roue centrale 24 entraîne le pignon central 18 qui lui est lié coaxialement, ce pignon central 18 entraînant à son tour la roue de commande 2 qui entraîne finalement dans un sens ou dans l'autre, selon le sens de rotation imprimé à la couronne 8 coiffant la tige 7, le nouveau pignon correcteur de fonction 3.The rotation of the
On relèvera pour terminer cette description que la présente invention n'est pas limitée au mode d'exécution particulier de la façon de faire préférée décrite dans le détail ci-dessus.It will be noted in conclusion that the present invention is not limited to the particular embodiment of the preferred method described in detail above.
On pourrait, par exemple, supprimer le second renvoi intermédiaire 41, et par voie de conséquence le premier renvoi intermédiaire 40, si le troisième ensemble était constitué d'une roue de renvoi principal 20 montée à friction sur le pignon de renvoi principal 21, le pignon 21 engrenant directement avec la roue d'étoile 16 et la roue 20 engrenant à la fois avec le deuxième ensemble constitué de la roue centrale 24 et du pignon central 18 et avec le train d'engrenages lié avec la tige 7, ce train possédant un moyen de débrayage radial commandé par le poussoir, lors de son activation.For example, the second
Dans cette version dérivée, le reste du mécanisme reste le même que celui mentionné à propos de la version préférée, l'idée principale de la présente invention consistant dans le fait qu'un poussoir 1 de changement de fonction déplace une roue de commande 2 pour l'amener en prise avec un pignon correcteur de la fonction choisie et qu'une tige 7, entraînée en rotation dans un sens ou dans l'autre, entraîne à son tour le pignon correcteur choisi pour corriger en plus ou en moins les données affichées de ladite fonction choisie.In this derivative version, the rest of the mechanism remains the same as that mentioned with respect to the preferred version, the main idea of the present invention consisting in the fact that a pusher 1 of change of function moves a
