Definitions
- the present invention relates to a unidirectional correction device for at least one time display member of a timepiece, said display member having a circular element provided with teeth.
- the document CH-A-607 556 aims to suppress such mobiles and to directly correct a date ring from a sliding pinion sliding on the time-setting rod.
- the sliding pinion has an annular groove in which is frictionally mounted a wire spring surrounding the groove on a little more than three quarters of its periphery.
- a free end of the wire spring extends radially beyond the periphery of the sliding pinion and serves directly as a drive finger for advancing or retreating the date ring by turning the rod respectively in one direction or the other.
- this construction does not lead to the solution offered by the present invention, namely a unidirectional correction device, since the spring of the cited document acts on the date ring in both directions of correction. It is a bidirectional device.
- the document CH-A-290 100 describes a unidirectional control system for the reassembly of an alarm clock.
- On the axis of the winding rod are mounted, one after the other, two sockets of the same diameter on which a coil spring is wound.
- One of the sockets is secured to the rod while the other is free on the same rod.
- the free socket is integral with a toothed wheel itself integral with a barrel spring.
- this is a coupling system where the coil spring can only act if it encloses two elements (two sockets) placed one next to the other, which has nothing in common with the present invention where the coil spring encloses only one element (a sliding pinion) and where said spring has a raised end which drives a second element (a date disc).
- the unidirectional correction device of the present invention is characterized in that it comprises a cylindrical element around which is wound with a slight tightening a coil spring, one end of which is raised radially to serve finger capable of coming into contact with a tooth of the circular element and rotating it when said cylindrical element is rotated in a direction in which the force exerted on the finger by the tooth is directed in a direction tending to wind the coil spring around the cylindrical element and tightening it around it, said circular element remaining stationary when the cylindrical element is rotated in a direction for which the force exerted on the finger by the tooth is directed in a steering tending to open the coil spring and to release it from said cylindrical element.
- Figures 1 and 4 show a unidirectional correction device 1 capable of correcting a time display member having a circular element 2 provided with teeth 3.
- the correction device 1 comprises a cylindrical element 4 around which is wound with a slight tightening, a coil spring 5. One end of this spring is raised radially to serve as a control finger 6.
- this finger 6 is capable of coming into contact with a tooth 3 of the circular element 2 and rotating this element in the direction of the arrow E when the cylindrical element 4 is driven in rotation in the direction of arrow A. Indeed, the resistance presented by tooth 3 against finger 6 develops a reaction force F1 which tends to wind the coil spring 5 around the cylindrical element 4 and hug him around him. It can be said that the coil spring locks around the cylindrical element to which it becomes integral.
- a unidirectional correction system has therefore been produced since the time indicator 2 is advanced if the device 1 is turned in one direction, this indicator remaining stationary if the device is turned in the direction reverse.
- the principle of the invention is very general and can be very simply verified by introducing a coil spring on a rod, the internal diameter of which is very slightly less than the diameter of the rod and one of the ends of which is raised along a radius of the rod to form a control finger.
- the device can be used in a timepiece, in particular for manual correction of various time indicators. It is clear however that it could be used wherever a one-way control is desired.
- the cylindrical element 4 around which is wound the coil spring 5 is carried by a sliding pinion 8, cooperating with a time-setting rod 9.
- the relative movement of the rod 9 relative to the sliding pinion 8 is ensured by a mechanism known elsewhere, and comprising in particular a pull tab 10 and a rocker 11.
- the sliding pinion comprises a toothing 12 in engagement here with a reference 13, the latter meshing with a timer wheel 14.
- the rod 9 is extended to the maximum and occupies a second pulled position which allows the hour and minute hands of the timepiece to be set to the time.
- the finger 6 of the coil spring 5 is not engaged in the teeth 3 of the circular element 2 which is here a date ring with internal teeth well known from the state of the art.
- Figure 4 shows a rod 9 occupying a first pulled position which allows the correction of the date ring 2.
- the finger 6 of the coil spring 5 is engaged in the teeth 3 of the ring.
- FIG. 5 which is a section along the line V-V in FIG. 4.
- Figure 3 shows the rod 9 in the neutral, pushed position. Here no correction is made because the finger 6 is not engaged in the toothing 3 of the ring 2 and the toothing 12 of the sliding pinion 8 does not mesh with the reference 13.
- FIG. 3 will also explain the way in which the sliding pinion 8 is executed.
- the first part comprises a hub 20 in which slides a square 21 ending the rod 9.
- the first part also carries a flange 22 preferably made in one piece with the hub.
- the second part comprises the toothed pinion 24 proper carrying the edge teeth 12.
- This pinion is extended by a neck 23 which forms the cylindrical element 4, which in turn carries the coil spring 5.
- FIG. 3 shows that the outer diameter of the neck 23 is smaller than the diameter of the toothed pinion 24 and the flange 22 so that the coil spring 5 is held in place axially between the two parts forming the sliding pinion.
- This construction by driving is especially advantageous to allow the mounting of the coil spring 5 which is slid over the neck 23 before the two parts in question are assembled.
- the coil spring 5 is wound with a slight tightening around the cylindrical element 4. This tightening is obtained by providing a spring whose internal diameter is slightly less than the diameter of the cylindrical element.
- the outside diameter of the neck 23 is 3.6 mm while the diameter of the coil spring 5 is 3.5 mm before mounting on the neck.
- the locking torque of the coil spring on the cylindrical element depends on the number of turns making up the spring and, to a certain extent, on the diameter of the wire used to make the spring.
- a spring made with 0.15 mm wire and comprising three turns gave excellent results.
- the correction device according to the invention acting in a unidirectional manner, it is possible to design a double device which, for a position drawn from the rod, corrects two different time indicators indicating for example, one the date and the other the day of the week and this following the direction of rotation of the rod. It is enough to have two coil springs, one wound in one direction and correcting the date and the other wound in the opposite direction and correcting the day of the week.
Abstract
Description
La présente invention concerne un dispositif de correction unidirectionnel d'au moins un organe d'affichage horaire d'une pièce d'horlogerie, ledit organe d'affichage présentant un élément circulaire pourvu de dents.The present invention relates to a unidirectional correction device for at least one time display member of a timepiece, said display member having a circular element provided with teeth.
Des systèmes de correction unidirectionnel d'un organe d'affichage horaire sont connus. Par exemple, le document EP-B-0 173 230 (US-A-4 634 287) décrit une pièce d'horlogerie universelle comportant un anneau de quantième et un disque faisant un pas en vingt-quatre heures. Selon qu'on tourne la tige de mise à l'heure dans un sens ou dans l'autre, on corrige soit les indications données par l'anneau, soit les indications données par le disque. Le mécanisme utilisé est un renvoi baladeur qui comporte une denture et un pignon à trois dents. Si l'on actionne la tige dans un sens, le renvoi se met dans une première position où la denture est en prise avec le disque. Si l'on actionne la tige dans le sens opposé, le renvoi se met dans une seconde position où le pignon est en prise avec l'anneau. Dans une telle construction plusieurs mobiles sont interposés entre la tige de commande et l'indicateur horaire qu'il faut corriger, ce qui conduit à une construction relativement compliquée et onéreuse.One-way correction systems for a time display member are known. For example, document EP-B-0 173 230 (US-A-4 634 287) describes a universal timepiece comprising a date ring and a disc making a step in twenty-four hours. Depending on whether one turns the time-setting rod in one direction or the other, one corrects either the indications given by the ring, or the indications given by the disc. The mechanism used is a sliding gear that has a toothing and a three-tooth pinion. If the rod is actuated in one direction, the gear returns to a first position where the teeth are in engagement with the disc. If the rod is actuated in the opposite direction, the gear returns to a second position where the pinion is engaged with the ring. In such a construction, several mobiles are interposed between the control rod and the time indicator which must be corrected, which leads to a relatively complicated and expensive construction.
Le document CH-A-607 556 a pour but de supprimer de tels mobiles et de corriger directement un anneau de quantième à partir d'un pignon coulant coulissant sur la tige de mise à l'heure. Pour cela, le pignon coulant présente une gorge annulaire dans laquelle est monté à friction un ressort-fil entourant la gorge sur un peu plus des trois quarts de sa périphérie. Une extrémité libre du ressort-fil dépasse radialement la périphérie du pignon coulant et sert directement de doigt d'entraînement pour avancer ou reculer l'anneau de quantième en tournant la tige respectivement dans un sens ou dans l'autre. Pour intéressante qu'elle soit, cette construction ne conduit pas à la solution que propose la présente invention, à savoir un dispositif de correction unidirectionnel, puisque le ressort-fil du document cité agit sur l'anneau de quantième dans les deux sens de correction. C'est un dispositif bidirectionnel.The document CH-A-607 556 aims to suppress such mobiles and to directly correct a date ring from a sliding pinion sliding on the time-setting rod. For this, the sliding pinion has an annular groove in which is frictionally mounted a wire spring surrounding the groove on a little more than three quarters of its periphery. A free end of the wire spring extends radially beyond the periphery of the sliding pinion and serves directly as a drive finger for advancing or retreating the date ring by turning the rod respectively in one direction or the other. However interesting it may be, this construction does not lead to the solution offered by the present invention, namely a unidirectional correction device, since the spring of the cited document acts on the date ring in both directions of correction. It is a bidirectional device.
Le document CH-A-290 100 décrit un système de commande unidirectionnel pour le remontage d'un réveil. Sur l'axe de la tige de remontage sont montées, l'une à la suite de l'autre, deux douilles de même diamètre sur lesquelles est bobiné un ressort à boudin. L'une des douilles est solidaire de la tige alors que l'autre est libre sur la même tige. La douille libre est solidaire d'une roue dentée elle-même solidaire d'un ressort de barillet. Quand la tige est entraînée en rotation dans un sens, le ressort à boudin se resserre autour des deux douilles pour les coupler ensemble et remonter ainsi le ressort de barillet. Quand la tige est entraînée en rotation dans l'autre sens, le ressort à boudin se desserre et la douille libre n'est pas entraînée. Il s'agit cependant là d'un système de couplage où le ressort à boudin ne peut agir que s'il enserre deux éléments (deux douilles) placés l'un à côté de l'autre, ce qui n'a rien de commun avec la présente invention où le ressort à boudin n'enserre qu'un seul élément (un pignon coulant) et où ledit ressort présente une extrémité relevée qui entraîne un second élément (un disque de quantième).The document CH-A-290 100 describes a unidirectional control system for the reassembly of an alarm clock. On the axis of the winding rod are mounted, one after the other, two sockets of the same diameter on which a coil spring is wound. One of the sockets is secured to the rod while the other is free on the same rod. The free socket is integral with a toothed wheel itself integral with a barrel spring. When the rod is rotated in one direction, the coil spring tightens around the two sockets to couple them together and thus reassemble the barrel spring. When the rod is rotated in the other direction, the coil spring loosens and the free sleeve is not driven. However, this is a coupling system where the coil spring can only act if it encloses two elements (two sockets) placed one next to the other, which has nothing in common with the present invention where the coil spring encloses only one element (a sliding pinion) and where said spring has a raised end which drives a second element (a date disc).
L'intérêt d'un système de correction unidirectionnel peut être vu dans l'économie des moyens mis en oeuvre lorsqu'il s'agit de corriger toute une série d'indicateurs horaires, comme cela est évoqué dans le premier document cité ci-dessus: quand on tourne la tige dans un sens, on corrige les données d'un indicateur et quand on tourne la tige dans l'autre sens, on corrige les données d'un autre indicateur. Un autre intérêt peut être vu tout simplement par la simplification qu'il apporte au mécanisme d'entraînement horaire de l'indicateur en question. On sait par exemple que ce mécanisme d'entraînement peut poser des problèmes de bon fonctionnement si l'indicateur horaire peut être corrigé manuellement dans les deux sens.The advantage of a unidirectional correction system can be seen in the economy of the means used when it is a question of correcting a whole series of hourly indicators, as was mentioned in the first document cited above. : when we turn the rod in one direction, we correct the data of one indicator and when we turn the rod in the other direction, we correct the data of another indicator. Another advantage can be seen quite simply by the simplification which it brings to the hourly drive mechanism of the indicator in question. We know, for example, that this drive mechanism can cause problems with proper operation if the time indicator can be corrected manually in both directions.
Pour répondre à ces questions et pour éviter les inconvénients cités, le dispositif de correction unidirectionnel de la présente invention est caractérisé en ce qu'il comporte un élément cylindrique autour duquel est enroulé avec un léger serrage un ressort à boudin dont une des extrémités est relevée radialement pour servir de doigt susceptible d'entrer en contact avec une dent de l'élément circulaire et le faire tourner quand ledit élément cylindrique est entraîné en rotation dans un sens pour lequel la force exercée sur le doigt par la dent est dirigée dans une direction tendant à enrouler le ressort à boudin autour de l'élément cylindrique et à le serrer autour de lui, ledit élément circulaire restant immobile quand l'élément cylindrique est entraîné en rotation dans un sens pour lequel la force exercée sur le doigt par la dent est dirigée dans une direction tendant à ouvrir le ressort à boudin et à le libérer dudit élément cylindrique.To answer these questions and to avoid the disadvantages mentioned, the unidirectional correction device of the present invention is characterized in that it comprises a cylindrical element around which is wound with a slight tightening a coil spring, one end of which is raised radially to serve finger capable of coming into contact with a tooth of the circular element and rotating it when said cylindrical element is rotated in a direction in which the force exerted on the finger by the tooth is directed in a direction tending to wind the coil spring around the cylindrical element and tightening it around it, said circular element remaining stationary when the cylindrical element is rotated in a direction for which the force exerted on the finger by the tooth is directed in a steering tending to open the coil spring and to release it from said cylindrical element.
L'invention sera expliquée maintenant à l'aide de la description qui suit, donnée à titre d'exemple, et en s'aidant du dessin qui l'illustre et dans lequel:
- la figure 1 est une vue en plan du dispositif selon l'invention, tige et pignon coulant étant représentés en position de mise à l'heure des indicateurs d'heure et de minute, la tige étant disposée en seconde position tirée,

- la figure 7 montre le déplacement du dispositif de la figure 5 dans le sens de la flèche B.

Les figures 1 et 4 montrent un dispositif de correction unidirectionnel 1 apte à corriger un organe d'affichage horaire présentant un élément circulaire 2 pourvu de dents 3. Selon l'invention, le dispositif de correction 1 comporte un élément cylindrique 4 autour duquel est enroulé avec un léger serrage, un ressort à boudin 5. Une des extrémités de ce ressort est relevée radialement pour servir de doigt de commande 6.Figures 1 and 4 show a
Comme on le voit sur la figure 6, ce doigt 6 est susceptible d'entrer en contact avec une dent 3 de l'élément circulaire 2 et faire tourner cet élément dans le sens de la flèche E quand l'élément cylindrique 4 est entraîné en rotation dans le sens de la flèche A. En effet, la résistance présentée par la dent 3 à l'encontre du doigt 6 développe une force de réaction F1 qui tend à enrouler le ressort à boudin 5 autour de l'élément cylindrique 4 et à le serrer autour de lui. On peut dire que le ressort à boudin se vérouille autour de l'élément cylindrique dont il devient solidaire.As can be seen in FIG. 6, this
Si l'on considère maintenant la figure 7 et qu'on actionne l'élément cylindrique 4 dans le sens de la flèche B, c'est-à-dire dans le sens opposé à celui considéré en figure 6, on voit que lorsque le doigt 6 appuie sur la dent 3, la force de réaction F2 développée sur le doigt 6 a tendance à ouvrir le ressort à boudin 5 et à le libérer de l'élément cylindrique 4, une telle situation étant symbolisée par l'espace 7 qu'on a dessiné entre l'élément 4 et le ressort à boudin 5. Le ressort 5 patine alors sur l'élément 4 et l'élément circulaire 2 reste immobile.If we now consider FIG. 7 and actuate the
En conclusion de ce qui vient d'être dit, on a donc réalisé un système unidirectionnel de correction puisque l'indicateur horaire 2 est avancé si le dispositif 1 est tourné dans un sens, cet indicateur restant immobile si le dispositif est tourné dans le sens inverse. Le principe de l'invention est très général et peut être très simplement vérifié en introduisant sur une tige, un ressort à boudin dont le diamètre intérieur est très légèrement inférieur au diamètre de la tige et dont une des extrémités est relevée selon un rayon de la tige pour former un doigt de commande. Le dispositif peut être mis à profit dans une pièce d'horlogerie notamment pour la correction manuelle de divers indicateurs horaires. Il est clair cependant qu'il pourrait être utilisé partout où une commande unidirectionnelle est souhaitée.In conclusion of what has just been said, a unidirectional correction system has therefore been produced since the
On va maintenant donner un exemple d'application de l'invention à un dispositif de correction d'un anneau de quantième portant des indications de dates, lesquelles apparaissent à travers un guichet percé dans un cadran.We will now give an example of application of the invention to a device for correcting a date ring bearing date indications, which appear through a window pierced in a dial.
Si l'on se reporte aux figures 1 et 2, on s'aperçoit que l'élément cylindrique 4 autour duquel est enroulé le ressort à boudin 5, est porté par un pignon coulant 8, coopérant avec une tige de mise à l'heure 9. Le mouvement relatif de la tige 9 par rapport au pignon coulant 8 est assuré par un mécanisme connu par ailleurs, et comportant notamment une tirette 10 et une bascule 11. Le pignon coulant comprend une denture de chant 12 en prise ici avec un renvoi 13, ce dernier engrenant avec une roue de minuterie 14. La tige 9 est sortie au maximum et occupe une seconde position tirée qui permet la mise à l'heure des aiguilles d'heure et de minute de la pièce d'horlogerie. Le doigt 6 du ressort à boudin 5 n'est pas engagé dans la denture 3 de l'élément circulaire 2 qui est ici un anneau de quantième à denture intérieure bien connu de l'état de l'art.If we refer to Figures 1 and 2, we see that the
La figure 4 montre une tige 9 occupant une première position tirée qui permet la correction de l'anneau de quantième 2. Pour cela le doigt 6 du ressort à boudin 5 est engagé dans la denture 3 de l'anneau. Cette situation est aussi représentée en figure 5 qui est une coupe selon la ligne V-V de la figure 4.Figure 4 shows a
A partir de la situation montrée en figure 5, si l'on tourne le dispositif de correction 1 dans le sens de la flèche A, le dos 15 du doigt 6 viendra heurter la dent 3 sur son flanc 16 et entraînera ladite dent jusqu'à ce qu'elle atteigne la position illustrée en figure 6 et cela grâce au principe de serrage du ressort à boudin expliqué plus haut. A partir de ce moment l'anneau 2 n'aura pas encore progressé d'un pas entier mais, dans la construction adoptée ici, aura parcouru environ les trois quarts du chemin. Comme cela apparaît en figure 1 la dent 3 se sera déplacée en 3′, le reste du parcours, de 3′ à 3˝ étant accompli grâce à la présence d'un sautoir 17.From the situation shown in FIG. 5, if the
De même, à partir de la situation montrée en figure 5, si l'on tourne le dispositif 1 dans le sens de la flèche B, le front 18 du doigt 6 viendra heurter la dent 3 sur son flanc 19 comme cela est représenté en figure 7. Dans ce cas le ressort 5 s'ouvre et l'anneau reste immobile comme expliqué plus haut.Similarly, from the situation shown in FIG. 5, if the
La figure 3 montre la tige 9 en position neutre, poussée. Ici aucune correction ne s'opère car le doigt 6 n'est pas engagé dans la denture 3 de l'anneau 2 et la denture 12 du pignon coulant 8 n'engrène pas avec le renvoi 13.Figure 3 shows the
La figure 3 permettra d'expliquer aussi la façon dont est exécuté le pignon coulant 8. Celui-ci est réalisé en deux parties chassées l'une dans l'autre. La première partie comporte un moyeu 20 dans lequel coulisse un carré 21 terminant la tige 9. La première partie porte encore un flasque 22 préférablement fait d'une pièce avec le moyeu. La seconde partie comporte le pignon denté 24 proprement dit portant la denture de chant 12. Ce pignon est prolongé par un col 23 qui forme l'élément cylindrique 4, qui porte à son tour le ressort à boudin 5. La figure 3 montre que le diamètre extérieur du col 23 est plus petit que le diamètre du pignon denté 24 et du flasque 22 de sorte que le ressort à boudin 5 est maintenu en place axialement entre les deux parties formant le pignon coulant. Cette construction par chassage est surtout intéressante pour permettre le montage du ressort à boudin 5 qui est glissé sur le col 23 avant que les deux parties en question soient assemblées.FIG. 3 will also explain the way in which the sliding
Selon une caractéristique de l'invention, le ressort à boudin 5 est enroulé avec un léger serrage autour de l'élément cylindrique 4. Ce serrage est obtenu en fournissant un ressort dont le diamètre intérieur est légèrement inférieur au diamètre de l'élément cylindrique. Dans la construction montrée en exemple à la figure 3, le diamètre extérieur du col 23 est de 3,6 mm alors que le diamètre du ressort à boudin 5 est de 3,5 mm avant montage sur le col.According to a characteristic of the invention, the
On notera encore que le couple de verrouillage du ressort à boudin sur l'élément cylindrique dépend du nombre de spires composant le ressort et, dans une certaine mesure, du diamètre du fil utilisé pour confectionner le ressort. Un ressort réalisé avec du fil de 0,15 mm et comportant trois spires a donné d'excellents résultats.It will also be noted that the locking torque of the coil spring on the cylindrical element depends on the number of turns making up the spring and, to a certain extent, on the diameter of the wire used to make the spring. A spring made with 0.15 mm wire and comprising three turns gave excellent results.
Le dispositif de correction selon l'invention agissant de manière unidirectionnelle, il est possible de concevoir un dispositif double qui, pour une position tirée de la tige, corrige deux indicateurs horaires différents indiquant par exemple, l'un le quantième et l'autre le jour de la semaine et cela suivant le sens de rotation de la tige. Il suffit pour cela de disposer de deux ressorts à boudin, l'un enroulé dans un sens et corrigeant le quantième et l'autre enroulé dans l'autre sens et corrigeant le jour de la semaine.The correction device according to the invention acting in a unidirectional manner, it is possible to design a double device which, for a position drawn from the rod, corrects two different time indicators indicating for example, one the date and the other the day of the week and this following the direction of rotation of the rod. It is enough to have two coil springs, one wound in one direction and correcting the date and the other wound in the opposite direction and correcting the day of the week.
