Description

L'invention est relative à un mécanisme de mise à l'heure pour pièce d'horlogerie du type comprenant une platine supportant un mouvement, mécanisme comportant une tige manoeuvrable de l'exté­rieur de la pièce au moyen d'une couronne, ladite tige pouvant prendre au moins deux positions axiales crantées, la première neutre et la seconde active, un pignon coulant coaxial à la tige et cou­lissant sur elle, ledit pignon coulant étant pourvu d'une denture conformée pour engrener sur un renvoi de mise à l'heure, la tige et le pignon coulant étant pourvus respectivement de portions mâle et femelle de section non circulaire et emboîtées l'une dans l'autre pour entraîner le pignon coulant en rotation quand la tige est manoeuvrée rotativement et un système de tirette et de bascule pour asservir le pignon coulant à la tige et mettre en prise ladite denture avec ledit renvoi quand ladite tige se trouve en position active.The invention relates to a time-setting mechanism for a timepiece of the type comprising a plate supporting a movement, mechanism comprising a rod which can be operated from the outside of the part by means of a crown, said rod being capable of take at least two notched axial positions, the first neutral and the second active, a sliding pinion coaxial with the rod and sliding on it, said sliding pinion being provided with a teeth shaped to mesh with a time-setting reference, the rod and the sliding pinion being provided respectively with male and female portions of non-circular cross section and nested one inside the other to drive the sliding pinion in rotation when the rod is rotated and a pull and rocker system for controlling the pinion flowing to the rod and engaging said toothing with said reference when said rod is in the active position.

Un mécanisme de mise à l'heure correspondant à la définition générique qui vient d'être donnée est bien connu de l'état de la technique et est montré par exemple dans le document CH-A-642 220. Dans ce document, la portion non circulaire mâle portée par la tige consiste en un carré qui peut coulisser dans un trou de forme cor­respondante pratiqué dans le pignon coulant. Comme on le voit des figures en coupe accompagnant le brevet cité, le diamètre extérieur du pignon coulant est notablement plus grand que le diamètre de la tige, ce qui prend de la place en épaisseur. Comme on le voit égale­ment de ces mêmes figures, la tige se termine, après le carré, par un pivot circulaire qui tourne et coulisse dans un orifice ménagé dans la platine. Cette façon de faire conduit à prendre une place non négligeable dans le sens du diamètre de la platine, ce qui amène finalement à augmenter le diamètre hors-tout de cette platine.A time-setting mechanism corresponding to the generic definition which has just been given is well known in the state of the art and is shown for example in document CH-A-642 220. In this document, the portion male non-circular carried by the rod consists of a square which can slide in a correspondingly shaped hole in the sliding pinion. As can be seen from the sectional figures accompanying the cited patent, the outside diameter of the sliding pinion is notably greater than the diameter of the rod, which takes up space in thickness. As can also be seen from these same figures, the rod ends, after the square, by a circular pivot which rotates and slides in an orifice formed in the plate. This procedure leads to taking a significant place in the direction of the diameter of the plate, which ultimately leads to increasing the overall diameter of this plate.

Pour pallier le premier inconvénient cité et diminuer l'épais­seur du mouvement, on a déjà construit des calibres dans lesquels le pignon coulant présente un diamètre extérieur du même ordre de gran­deur que le diamètre de la tige. Pour ce faire, on a pratiqué à l'extrémité de la tige une portion mâle non circulaire comportant deux plats s'engageant dans une saignée pratiquée dans le pignon coulant. Cette solution, en plus de l'avantage qu'elle apporte de réduire le diamètre dudit pignon, permet une fabrication très simple puisque la saignée est réalisée par un simple passage de fraise. Comme dans la solution proposée, l'extrémité de la tige côté mouve­ment est dépourvue de pivot coulissant dans un palier, on a guidé le pignon coulant dans un orifice pratiqué dans la platine. Cet orifice cependant présente des parois très minces qui risquent d'être endom­magées par les plats de la tige si cette tige n'est pas suffisamment bien guidée. On a alors tourné la difficulté en guidant cette tige sur un parcours plus long à son entrée dans la platine, côté cou­ronne, avec l'inconvénient de prendre une place au moins aussi importante que si la tige était munie d'un pivot coulissant dans la platine, comme c'était le cas dans le brevet cité ci-dessus.To overcome the first drawback mentioned and reduce the thickness of the movement, calibers have already been constructed in which the sliding pinion has an outside diameter of the same order of magnitude as the diameter of the rod. To do this, we practiced the end of the rod a non-circular male portion comprising two dishes engaging in a groove made in the sliding pinion. This solution, in addition to the advantage that it brings of reducing the diameter of said pinion, allows a very simple manufacture since the bleeding is carried out by a simple passage of cutter. As in the proposed solution, the end of the rod on the movement side has no sliding pivot in a bearing, the sliding pinion has been guided in an orifice made in the plate. This orifice, however, has very thin walls which may be damaged by the dishes of the rod if the rod is not sufficiently well guided. We then turned the difficulty by guiding this rod on a longer path at its entry into the plate, crown side, with the disadvantage of taking a place at least as important as if the rod were provided with a pivot pivot in the platinum, as was the case in the patent cited above.

Pour éviter cet inconvénient et proposer un mouvement dont l'encombrement en plan est réduit au maximum, on utilisera les moyens qui sont décrits dans la revendication 1.To avoid this drawback and to propose a movement whose space requirement in plan is reduced to the maximum, one will use the means which are described in claim 1.

L'invention sera comprise maintenant à la lecture de la des­cription qui suit et qui donne, à titre d'exemple, une forme de réalisation pour l'intelligence de laquelle on se référera au dessin dans lequel :

  • - la figure 1 est une vue en plan du dispositif de mise à l'heure selon l'invention;
  • - la figure 2a est une coupe selon la ligne II-II de la figure 1 quand la tige est en première position enfoncée neutre;
  • - la figure 2b est une coupe selon la ligne II-II de la figure 1 quand la tige est en seconde position active tirée; et
  • la figure 3 est une coupe selon la ligne III-III de la figure 2b.
The invention will now be understood on reading the description which follows and which gives, by way of example, an embodiment for the understanding of which reference will be made to the drawing in which:
  • - Figure 1 is a plan view of the time setting device according to the invention;
  • - Figure 2a is a section along the line II-II of Figure 1 when the rod is in the first neutral pressed position;
  • - Figure 2b is a section along line II-II of Figure 1 when the rod is in the second active position pulled; and
  • Figure 3 is a section along line III-III of Figure 2b.

La figure 1 est une vue en plan du dispositif de mise à l'heure selon l'invention. La pièce d'horlogerie comprend une platine 1, un ensemble tirette 2 et bascule 3 liées respectivement à une tige 4 et à un pignon coulant 5, un logement 6 pour une batterie et un rouage 7. L'extrémité 8 du pignon coulant comporte une denture de chant (désignée par 9 dans les figures 2a et 2b). En position tirée de la tige 4, le pignon coulant vient engrener sur un renvoi 10 de mise à l'heure faisant partie du rouage 7. La tirette 2 pivote autour de l'axe 11. Elle comprend un nez 12 engagé dans une gorge 13 pratiquée dans la tige 4. La tirette comporte encore un plot 14 qui coopère avec des crans 15 et 16 dont est munie la bascule 3. Le renfoncement 17 est un logement dans lequel on peut appuyer une pointe pour sou­lever le nez 12, ce qui permet d'extraire la tige 4 du mouvement. La bascule 3 est en forme de V pivotant en 18. Une des branches 19 du V est élastique et son extrémité 20 vient s'appuyer sur l'axe 11 de la tirette. L'autre branche 21 de la bascule 3 comprend un premier bras 22 destiné à maintenir la tirette dans un plan et un second bras 23 dans lequel sont pratiquées les échancrures 15 et 16. Le second bras 23 se termine par un bec 24 engagé dans une gorge 25 du pignon coulant 5. La branche 21 de la bascule est maintenue en place par un tenon 26. La tirette et la bascule sont dessinées en position pour laquelle la tige est en position neutre enfoncée. Pour cette posi­tion, le plot 14 est cranté dans l'échancrure 15 et le bec 24 main­tient le pignon coulant vers le haut de la figure, ce qui fait que l'extrémité 8 dudit pignon est dégagé du renvoi 10. On a dessiné en traits mixtes les positions occupées par le bec 24', le nez 12' et le plot 14' quand la tige 4 est en position active tirée. Dans cette position, le plot 14' vient se cranter dans l'échancrure 16 et l'ex­trémité 8' du pignon coulant vient en prise avec le renvoi 10.Figure 1 is a plan view of the time setting device according to the invention. The timepiece comprises a plate 1, a pull tab 2 and rocker 3 assembly linked respectively to a rod 4 and to a sliding pinion 5, a housing 6 for a battery and a gear train 7. The end 8 of the sliding pinion comprises a edge teeth (designated by 9 in Figures 2a and 2b). In the pulled position of the rod 4, the sliding pinion meshes with a return 10 for setting the hour forming part of the train 7. The zipper 2 pivots about the axis 11. It comprises a nose 12 engaged in a groove 13 formed in the rod 4. The zipper also comprises a stud 14 which cooperates with notches 15 and 16 which is provided with the lever 3. The recess 17 is a housing in which one can press a point to raise the nose 12, which allows the rod 4 to be extracted from the movement. The lever 3 is in the form of a V pivoting at 18. One of the arms 19 of the V is elastic and its end 20 comes to bear on the axis 11 of the pull tab. The other branch 21 of the rocker 3 comprises a first arm 22 intended to hold the zipper in a plane and a second arm 23 in which the notches 15 and 16 are made. The second arm 23 ends in a spout 24 engaged in a groove 25 of the sliding pinion 5. The branch 21 of the rocker is held in place by a lug 26. The puller and the rocker are drawn in position for which the rod is in the pressed-in neutral position. For this position, the stud 14 is notched in the notch 15 and the spout 24 maintains the pinion flowing upwards in the figure, which means that the end 8 of said pinion is released from the reference 10. We have drawn in lines mixed the positions occupied by the spout 24 ', the nose 12' and the stud 14 'when the rod 4 is in the active pulled position. In this position, the stud 14 'is notched in the notch 16 and the end 8' of the sliding pinion engages with the reference 10.

La tige 4 comprend une portion mâle de section non circulaire comportant deux plats 27 engagés dans une saignée (non visible sur la figure 1) pratiquée dans le pignon coulant 5. Selon l'invention, la tige 4 comporte en outre à son extrémité opposée à la couronne de commande (non représentée) un pivot 28 engagé dans un trou 29 du pignon coulant 5. La figure 1 fait comprendre comment fonctionne le mécanisme de tirette et de bascule pour asservir le pignon coulant à la tige, mécanisme connu en soi.The rod 4 comprises a male portion of non-circular section comprising two dishes 27 engaged in a groove (not visible in FIG. 1) formed in the sliding pinion 5. According to the invention, the rod 4 also comprises at its end opposite to the control crown (not shown) a pivot 28 engaged in a hole 29 of the sliding pinion 5. FIG. 1 shows how the pull and tilt mechanism works to control the sliding pinion to the rod, a mechanism known in itself.

Les figures 2a et 2b sont des coupes selon la ligne II-II de la figure 1. La figure 2a montre en détail le rouage 7 évoqué à propos de la figure 1. Solidaire de la chaussée 30 qui porte l'aiguille des minutes (non représentée), on trouve la roue des minutes 31 qui est entraînée par un organe moteur. Un pignon 32 solidaire de la roue des minutes entraîne une minuterie comprenant la roue 33 et le pignon 34. Le pignon 34 entraîne à son tour la roue à canon des heures 35 solidaire de l'aiguille des heures (non représentée). La roue de minuterie est en prise avec le renvoi de mise à l'heure 10 sur lequel peut agir la commande de mise à l'heure par la denture de chant 9. Le système de mise à l'heure proprement dit est représenté en figure 2a lorsque la tige est en position neutre enfoncée et en figure 2b lorsque cette tige est en position active tirée. Le sys­tème présente une tige 4 actionnée par une couronne (non représen­tée). Dans la gorge 13 de la tige 4 est engagé le nez 12 de la tirette 2 (voir aussi figure 1). La tige se poursuit par une portion mâle non circulaire 40 qui présente deux plats 27 dirigés dans le sens perpendiculaire au dessin. Cette portion 40 est engagée dans une saignée 41 pratiquée dans le pignon coulant 5. Ainsi quand la tige tourne, le pignon coulant tourne avec elle. La tige comprend encore au-delà de la portion 40 un pivot circulaire 28 qui est enga­gé et adapté librement dans un trou 29 dont est muni le pignon cou­lant 5. Le trou 29 s'arrête à la ligne pointillée référencée 42 à partir de laquelle commence la saignée 41. Le pignon coulant 5 com­porte en outre une gorge 25 dans laquelle est engagé le bec 24 de la bascule 3 (voir aussi figure 1).Figures 2a and 2b are sections along the line II-II of Figure 1. Figure 2a shows in detail the cog 7 mentioned in connection with Figure 1. Solid with the carriageway 30 which carries the minute hand (not shown), there is the minute wheel 31 which is driven by a drive member. A pinion 32 integral with the minute wheel drives a timer comprising the wheel 33 and the pinion 34. The pinion 34 in turn drives the barrel wheel of the 35 hours secured to the hour hand (not shown). The timer wheel is engaged with the time setting reference 10 on which the time setting control can act by the edge teeth 9. The time setting system itself is shown in FIG. 2a when the rod is in the inserted neutral position and in FIG. 2b when this rod is in the active pulled position. The system has a rod 4 actuated by a crown (not shown). In the groove 13 of the rod 4 is engaged the nose 12 of the pull tab 2 (see also Figure 1). The rod continues with a non-circular male portion 40 which has two dishes 27 directed in the direction perpendicular to the drawing. This portion 40 is engaged in a groove 41 formed in the sliding pinion 5. Thus when the rod rotates, the sliding pinion rotates with it. The rod also comprises, beyond the portion 40, a circular pivot 28 which is freely engaged and adapted in a hole 29 which is fitted with the sliding pinion 5. The hole 29 stops at the dotted line referenced 42 from which begins the groove 41. The sliding pinion 5 further comprises a groove 25 in which is engaged the spout 24 of the lever 3 (see also Figure 1).

Comme on le voit bien en figures 2a et 2b, la tige 4 est enga­gée côté couronne dans un premier orifice circulaire 43 pratiqué dans la platine 1. Il en est de même du pignon coulant 5 qui est guidé dans un second orifice circulaire 44 pratiqué dans la platine 1. Ainsi grâce au pivot 28 de la tige engagé dans le trou 29 du pignon coulant, ce dernier étant lui-même guidé dans la platine, et grâce à l'orifice 43 dans lequel est guidé l'avant de la tige, toute la tige 4 est parfaitement guidée à l'intérieur de la platine. En d'autres termes, la tige reste alignée entre deux paliers supports, le premier étant l'orifice 43 guidant et centrant la tige proprement dite et le second étant l'orifice 44 guidant et centrant le pignon coulant lui-même servant de palier au pivot pratiqué à l'extrémité de la tige.As can be seen in FIGS. 2a and 2b, the rod 4 is engaged on the crown side in a first circular orifice 43 formed in the plate 1. The same is true of the sliding pinion 5 which is guided in a second circular orifice 44 formed in the plate 1. Thus, thanks to the pivot 28 of the rod engaged in the hole 29 of the sliding pinion, the latter being itself guided in the plate, and thanks to the orifice 43 in which the front of the rod is guided, the whole rod 4 is perfectly guided inside the plate. In other words, the rod remains aligned between two support bearings, the first being the orifice 43 guiding and centering the rod proper and the second being the orifice 44 guiding and centering the sliding pinion itself serving as a bearing for the pivot at the end of the rod.

La figure 3 est une coupe selon la ligne III-III de la figure 2b. On voit que le pignon coulant 5 est ajusté dans l'orifice 44 percé dans la platine 1. A l'arrière du pivot 28 on distingue la portion non circulaire 40 portée par la tige 4 ainsi que les plats 27 de cette portion et les bords de la saignée 41 du pignon coulant entre lesquels coulissent les plats 27.Figure 3 is a section along line III-III of Figure 2b. We see that the sliding pinion 5 is adjusted in the orifice 44 drilled in the plate 1. At the rear of the pivot 28 there is a non-circular portion 40 carried by the rod 4 as well as the dishes 27 of this portion and the edges of the groove 41 of the sliding pinion between which the dishes 27 slide.

La construction décrite ici à titre d'exemple n'est pas limitée à l'utilisation de deux plats 27 pour la tige 4. Ce pourrait être un carré ou toute autre forme non circulaire. De même, le diamètre du pivot 28 est représenté comme étant égal à la distance qui sépare les deux plats. On comprendra que ce diamètre pourra être plus petit que la distance en question.The construction described here by way of example is not limited to the use of two dishes 27 for the rod 4. It could be a square or any other non-circular shape. Similarly, the diameter of the pivot 28 is shown as being equal to the distance between the two dishes. It will be understood that this diameter may be smaller than the distance in question.

De la description ci-dessus on comprend l'avantage qu'on peut tirer d'une telle construction. En effet, le pivot 28 n'étant pas guidé dans un trou pratiqué dans la platine comme c'est le cas de l'art antérieur, mais dans un trou faisant partie du pignon coulant lui-même guidé à son tour dans la platine, on gagne une place consi­dérable dans le sens de l'encombrement diamétral de la pièce d'hor­logerie. De plus, il n'y a plus de risque d'abîmer la platine par les bords des plats quand la tige est entraînée en rotation puisque la tige reste toujours alignée dans son logement.From the above description we understand the advantage that can be drawn from such a construction. Indeed, the pivot 28 not being guided in a hole made in the plate as is the case in the prior art, but in a hole forming part of the sliding pinion itself guided in its turn in the plate, a considerable space is gained in the direction of the diametrical bulk of the timepiece. In addition, there is no longer any risk of damaging the plate by the edges of the dishes when the rod is rotated since the rod always remains aligned in its housing.
