Le dispositif selon l'invention, comprenant un organe d'indication d'une valeur à afficher montée sur un axe de rotation, est caractérisé en ce qu'il comprend des moyens agencés pour commander l'organe d'indication de manière à ce que son extrémité libre suive le cheminement choisi selon la rotation autour de l'axe.The device according to the invention, comprising a member for indicating a value to be displayed mounted on an axis of rotation, is characterized in that it comprises means arranged to control the indication member so that its free end follows the path chosen according to the rotation around the axis.

Selon un premier mode d'exécution, les moyens de commande de l'organe d'indication peuvent comprendre une rainure longitudinale coulissant sur deux goupilles montées sur un bras de guidage, lui-même solidaire de l'axe de rotation.According to a first embodiment, the control means of the indication member can comprise a longitudinal groove sliding on two pins mounted on a guide arm, itself secured to the axis of rotation.

Les moyens de commande de l'organe d'indication peuvent comprendre une rainure transversale guidée par une goupille montée sur un bras en liaison cinématique avec le bras de guidage.The means for controlling the indication member may include a transverse groove guided by a pin mounted on an arm in kinematic connection with the guide arm.

Selon un deuxième mode d'exécution, les moyens de commande de l'organe d'indication comprennent un pignon comportant une denture partielle engrainant avec une denture placée à l'intérieur d'un évidemment pratiqué dans l'organe d'indication et prolongeant la rainure longitudinale.According to a second embodiment, the control means of the indication member comprise a pinion comprising a partial toothing causing with a toothing placed inside a recess made in the indication member and extending the longitudinal groove.

La denture peut comprendre deux parties opposées placées de part et d'autre de l'évidemment, le pignon engrainant l'une après l'autre les deux parties opposées de la denture et provoquant ainsi un mouvement de va et vient de l'organe d'indication de la valeur à afficher.The teeth may include two opposite parts placed on either side of the recess, the pinion causing one after the other the two opposite parts of the teeth and thus causing a back and forth movement of the organ d indication of the value to display.

Selon un mode d'exécution préféré, l'organe d'indication de la valeur à afficher est une aiguille.According to a preferred embodiment, the member for indicating the value to be displayed is a needle.

Dans la figure 1 est représentée une montre conventionnelle 1 où l'aiguille des minutes 2 effectue un parcours selon un mouvement circulaire. L'extrémité libre de l'aiguille 2 parcourt ainsi un cercle 3, de manière à suivre le cheminement ou chemin de fer des minutes figurant sur le cadran.In Figure 1 is shown a conventional watch 1 where the minute hand 2 travels in a circular motion. The free end of the needle 2 thus traverses a circle 3, so as to follow the path or railway of the minutes appearing on the dial.

Dans le mode d'exécution représenté dans la figure 2, l'extrémité libre ou pointe de l'aiguille des minutes 4 effectue un parcours selon un ovale 5 qui figure le cheminement choisi ou chemin de fer imprimé sur le cadran 6. Il est évident pour l'homme de métier que l'aiguille des minutes 4 est représentée à titre d'exemple, et que cette aiguille 4 pourrait être l'aiguille des heures, ou l'aiguille des secondes, ou encore un élément d'indication de toute autre donnée, par exemple jour, mois, année, etc. ...In the embodiment represented in FIG. 2, the free end or tip of the minute hand 4 travels along an oval 5 which represents the chosen path or railway printed on the dial 6. It is obvious for those skilled in the art that the minute hand 4 is shown by way of example, and that this hand 4 could be the hour hand, or the second hand, or even an element for indicating any other data, for example day, month, year, etc. ...

L'aiguille 4 représentée en vue de dessous dans la figure 3 présente deux rainures 7 et 8. La rainure 7 peut présenter une configuration choisie en fonction du chemin que l'extrémité de l'aiguille 4 est censée effectuer et la rainure 8 est une rainure longitudinale selon l'axe de l'aiguille.The needle 4 shown in bottom view in FIG. 3 has two grooves 7 and 8. The groove 7 can have a configuration chosen according to the path that the end of the needle 4 is supposed to make and the groove 8 is a longitudinal groove along the axis of the needle.

L'aiguille 4 est entraînée par un dispositif ou module additionnel monté sur une pièce d'horlogerie non représenté. Le dispositif ou module additionnel, qui sera décrit plus loin en regard de la figure 6, comprend deux bras 9 et 10 (figure 4) assemblés l'un sur l'autre au centre du mouvement de la pièce d'horlogerie. Le bras 9 effectue une rotation complète par heure et est solidaire du mécanisme d'indication de l'heure de la pièce d'horlogerie, et le bras 10 est également entraîné par le mécanisme d'indication de l'heure, de manière à effectuer deux tours complets par heure. Sur les bras 9 et 10, sont chassées des goupilles 11, 12 et 13, et l'aiguille 4 est placée sur les bras 9 et 10, de manière à ce que la rainure 7 coïncide avec la goupille 13, la rainure 8 étant positionnée par les goupilles 11 et 12. Ainsi, la rainure 8 permet de guider l'aiguille des minutes et de leur faire effectuer un tour en une heure. La goupille 13 chassée sur le bras 10 permet de guider l'aiguille 4 en lui faisant parcourir un ovoïde.The needle 4 is driven by an additional device or module mounted on a timepiece, not shown. The additional device or module, which will be described later with reference to FIG. 6, comprises two arms 9 and 10 (FIG. 4) assembled one on the other at the center of the movement of the timepiece. The arm 9 performs one complete rotation per hour and is integral with the mechanism for indicating the time of the timepiece, and the arm 10 is also driven by the mechanism for indicating the time, so as to effect two full turns per hour. Pins 11, 12 and 13 are driven out of arms 9 and 10, and needle 4 is placed on arms 9 and 10, so that groove 7 coincides with pin 13, groove 8 being positioned by pins 11 and 12. Thus, the groove 8 makes it possible to guide the minute hand and make them perform one revolution in one hour. The pin 13 driven out of the arm 10 makes it possible to guide the needle 4 by making it pass through an ovoid.

Ainsi, comme représenté dans la figure 5, le parcours de l'aiguille 4 sur le cadran est défini par la vitesse de rotation du bras 10 par rapport au bras 9, et par la forme de la rainure 7. Cette dernière permet d'affiner la courbe du parcours du chemin de fer, suivant la forme donnée à cette rainure. Elle peut être rectiligne ou courbe.Thus, as shown in FIG. 5, the path of the needle 4 on the dial is defined by the speed of rotation of the arm 10 relative to the arm 9, and by the shape of the groove 7. The latter makes it possible to refine the curve of the path of the railway, according to the shape given to this groove. It can be straight or curved.

Pour notre cas, on a choisi que le bras 10 tourne deux fois plus vite que le bras 9, car on veut que l'aiguille soit plus grande à midi et à six heures, et qu'elle soit plus petite à trois heures et à neuf heures.For our case, we chose that the arm 10 rotates twice as fast as the arm 9, because we want the needle to be larger at noon and at six o'clock, and that it is smaller at three o'clock and at nine o'clock.

Le mécanisme de commande de l'aiguille 4 des figures 3 à 5 est représenté en coupe dans la figure 6.The mechanism for controlling the needle 4 in FIGS. 3 to 5 is shown in section in FIG. 6.

L'aiguille indicatrice 4, pour notre cas aiguille des minutes, est positionnée tout en haut de l'empilement du mécanisme de la figure 6. Une roue 14 est solidaire de la chaussée du calibre de base 15, et donc tourne un tour par heure. Le pignon 16 et la roue 17 forment un renvoi qui permet de multiplier la vitesse de la roue 18a. Pour notre cas, deux tours par heure pour un ovale. Sur cette dernière est chassé le bras 9 qui entraîne l'aiguille 4. Ensuite, pour entraîner le bras 10 qui tourne deux fois par heure on a installé un renvoi simple 18 entre les roues 14 et 19. De ce fait, le bras n°3 fait deux tours par heure.The indicator hand 4, in our case minute hand, is positioned at the very top of the stack of the mechanism of FIG. 6. A wheel 14 is integral with the roadway of the base caliber 15, and therefore rotates one revolution per hour . The pinion 16 and the wheel 17 form a reference which makes it possible to multiply the speed of the wheel 18a. In our case, two turns per hour for an oval. On the latter is driven the arm 9 which drives the needle 4. Then, to drive the arm 10 which rotates twice an hour we installed a simple return 18 between the wheels 14 and 19. Therefore, the arm No. 3 makes two revolutions per hour.

L'aiguille des heures est chassée sur la roue des heures 19. Le mécanisme qui vient d'être décrit est monté sur une platine 20 qui vient se poser sur le calibre de base ou la pièce d'horlogerie.The hour hand is driven onto the hour wheel 19. The mechanism which has just been described is mounted on a plate 20 which comes to rest on the base caliber or the timepiece.

L'aiguille 4 peut présenter différentes formes, par exemple la forme représentée dans la figure 7. En règle générale, la forme de l'aiguille sera déterminée par la contrainte occasionnée par la présence des moyens nécessaires à la commande de l'aiguille, notamment les deux rainures 7 et 8 (figure 5). D'autre part, le parcours réalisé par l'extrémité libre de l'aiguille peut également être choisi en fonction de critères artistiques ou pratiques d'adaptation à la forme de la pièce d'horlogerie. Le parcours de l'extrémité libre de l'aiguille représenté dans la figure 8 en est un exemple. Dans ce cas, le bras 10 (figure 5), tourne trois fois plus vite que le bras 9. Dans l'exemple des figures 9 ou 10, le bras 10 effectue quatre rotations complètes pour une rotation effectuée par le bras 9.The needle 4 can have different shapes, for example the shape shown in FIG. 7. As a general rule, the shape of the needle will be determined by the stress caused by the presence of the means necessary for controlling the needle, in particular the two grooves 7 and 8 (Figure 5). On the other hand, the route made by the free end of the needle can also be chosen according to artistic or practical criteria of adaptation to the shape of the timepiece. The path of the free end of the needle shown in Figure 8 is an example. In this case, the arm 10 (FIG. 5) rotates three times faster than the arm 9. In the example of FIGS. 9 or 10, the arm 10 performs four complete rotations for one rotation performed by the arm 9.

L'exemple de la figure 10 peut être appliqué à la réalisation d'une montre carrée, de même que l'exemple de la figure 9 pour lequel il suffit de prévoir une rotation de 45° pour l'ensemble du dispositif par rapport à la pièce d'horlogerie.The example in FIG. 10 can be applied to the production of a square watch, as can the example in FIG. 9 for which it suffices to provide a 45 ° rotation for the entire device in relation to the timepiece.

Le deuxième mode d'exécution du dispositif d'affichage analogique représenté dans les figures 11 à 14 comprend un cadran 21 sur lequel est imprimé un cheminement préalablement choisi ou chemin de fer 22. Dans la figure 11, le chemin de fer 22 se présente sous forme d'un ovale. Il peut cependant se présenter sous toute autre forme, par exemple carrée, et l'organe d'affichage 23 peut être une aiguille d'heures, de minutes, de secondes, ou de toute autre indication.The second embodiment of the analog display device shown in FIGS. 11 to 14 comprises a dial 21 on which a previously chosen path or railway 22 is printed. In FIG. 11, the railway 22 appears under shape of an oval. However, it can be in any other form, for example square, and the display member 23 can be an hour, minute, second hand, or any other indication.

Le dispositif des figures 11 à 13 est composé principalement de trois pièces :

  • Une aiguille 23 contenant une denture à crémaillère 24
  • Un bras 25 guidant l'aiguille et ses deux goupilles 26 et 27
  • Un pignon partiellement denté 28.
The device in FIGS. 11 to 13 is mainly composed of three parts:
  • A needle 23 containing rack and pinion teeth 24
  • An arm 25 guiding the needle and its two pins 26 and 27
  • A partially toothed pinion 28.

Sur le bras 25, sont chassées les deux goupilles 26 et 27 destinées à guider l'aiguille 23. Cette dernière comporte en son intérieur la denture 24. Le pignon 28 placé au centre du calibre comporte une denture partielle 29. Il tourne dans le sens horaire engrainant avec la denture 24 de l'aiguille 23. Pour obtenir une forme ovale comme représenté dans la figure 14 avec le mécanisme qui vient d'être décrit, le parcours de l'aiguille est défini par la crémaillère 24 utilisée. Le dispositif décrit est aussi orientable de 360° par rapport au calibre de base.On the arm 25, are driven the two pins 26 and 27 intended to guide the needle 23. The latter has inside its toothing 24. The pinion 28 placed in the center of the gauge has a partial toothing 29. It rotates in the direction schedule causing with the toothing 24 of the needle 23. To obtain an oval shape as shown in the figure 14 with the mechanism which has just been described, the path of the needle is defined by the rack 24 used. The device described can also be rotated 360 ° relative to the basic rating.

Le dispositif des figures 11 à 13 fonctionne comme suit :

  • Une fois le pignon 28 arrivé en bout de course avec la partie droite de la denture 24 (Figure 13), il engraine avec la partie gauche. Et ainsi de suite. De ce fait, l'aiguille 23 fait un mouvement de va et vient entre sa position maximale et sa position minimale. La figure 13 montre la position minimale de l'aiguille. Pour notre cas, elle se situe à 3 heures ou à 9 heures.
  • Le parcours de l'aiguille 23 est défini par la vitesse de rotation du pignon 28 par rapport au bras 25. En effet, si le pignon 28 va deux fois plus vite que le bras 25, il en résultera un ovale (figure 11) tandis que s'il va quatre fois plus vite, le parcours sera pratiquement carré (Figure 14). Il faut savoir que ces parcours ne sont pas modifiables en variant la forme d'une pièce. On peut agir uniquement sur la vitesse des mobiles 25 et 28. En effet, la forme du pignon ne peut être changée étant donné qu'il engraine avec la crémaillère 24 de l'aiguille 23. Et si on change le nombre de dents, il en résulte uniquement un meilleur engrainement. Mais aucunement une modification du chemin de fer de l'aiguille.
The device in FIGS. 11 to 13 operates as follows:
  • Once the pinion 28 has reached the end of its travel with the right part of the toothing 24 (Figure 13), it drives with the left part. And so on. Therefore, the needle 23 makes a back and forth movement between its maximum position and its minimum position. Figure 13 shows the minimum needle position. In our case, it is at 3 o'clock or 9 o'clock.
  • The path of the needle 23 is defined by the speed of rotation of the pinion 28 relative to the arm 25. In fact, if the pinion 28 goes twice as fast as the arm 25, this will result in an oval (FIG. 11) while that if it goes four times faster, the course will be practically square (Figure 14). You should know that these routes cannot be modified by varying the shape of a room. We can act only on the speed of the mobiles 25 and 28. In fact, the shape of the pinion cannot be changed since it engages with the rack 24 of the needle 23. And if we change the number of teeth, it results only better training.
