Description

  

   <Desc/Clms Page number 1> 
 Pièce d'horlogerie à remontage automatique par rotor Dans les pièces d'horlogerie à remontage automatique par rotor, la tige de remontoir et sa liaison cinématique avec les organes de remontage à la main et ceux de mise à l'heure, occupent un espace en dehors duquel se meut ledit rotor ou masse de remontage, ce qui augmente la hauteur .de la pièce et s'oppose à une réalisation du type dit extra-plat. 



  11 a déjà été proposé de diminuer cette hauteur en disposant le rotor en dehors de la zone du mouvement comportant le barillet et le balancier. Cette solution présente toutefois le désavantage de réduire notablement le rayon de giration de la masse et s'oppose à la profiler en forme de cloche, dont la jante épaisse constitue la principale source d'énergie en cours de remontage. 



  Afin de pouvoir utiliser un tel profil, la présente invention prévoit que l'espace balayé par le rotor entoure la totalité du mouvement, à l'exception de la lige de remontoir, la roue de couronne reliant cette tige au mouvement et une bascule étant situées sous l'espace balayé par le rotor, offrant ainsi un libre passage à sa jante. 



  Le dessin annexé montre une forme d'exécution de l'objet de l'invention, donnée à titre d'exemple. La    fig.   1 est une vue    semi-schématique   de la pièce montrant la disposition générale adoptée. 



  La    fig.   2 est une demi-vue de la pièce à plus grande échelle, montrant la disposition des éléments de remontage et de mise à l'heure indiquée. 



  La    fig.   3 en est une coupe radiale selon l'axe de la tige de remontoir, à plus grande échelle encore. Dans la pièce    semi-schématiquement   représentée à la    fig.   1, on voit un centre 1, entouré d'un cercle 2. Ce sont le centre de la pièce et son pourtour extérieur. On y voit un second centre 3, excentré, entouré d'un cercle 4. Ce sont le centre de rotation de la masse du rotor et le pourtour extérieur de l'espace balayé par ce dernier. 



  Du fait que les centres 1 et 3 ne coïncident pas, il subsiste entre l'espace précédemment cité et le profil extérieur de la pièce une lunule 5. C'est dans cette dernière que pénètre et se situe la tige de remontage 6, qui ne peut par conséquent s'opposer aux déplacements du rotor. 



  La coupe de la    fig.   3 montre, en effet, comment ce rotor 4 passe devant la tige de remontoir G et non par-dessus comme cela se fait habituellement, ce qui permet d'abaisser le niveau dudit rotor en direction du cadran. 



  Cette disposition nécessite toutefois un mécanisme modifié de transmission des mouvements de la tige de remontoir. Ce mécanisme est, pour cette raison, entièrement placé dans un plan compris entre l'axe de ladite tige et le cadran. Les    fig.   2 et 3 le représentent en détail. 



  Le pignon coulant habituel est remplacé par un pignon 7    axialement   fixe et entraînant la roue de couronne 8, sur l'axe de laquelle oscille une bascule 9, porteuse de deux renvois 10 et 11. Ceux-ci sont constamment en prise avec la roue de couronne 8 mais peuvent, selon la position de la bascule 9, agir soit sur le remontage, soit sur la mise à l'heure. 



  En    fig.   2, la position représentée de la bascule et celle en traits pleins des renvois 10 et 11 correspondent au remontage, le renvoi 10 établissant la liaison entre la roue de couronne 8 et le rochet 12. Une oscillation de la bascule 9 dans le sens horaire par rapport à la    fig.   2 amènerait au contraire les renvois 10 et 11 dans la position représentée en traits mixtes. Dans cette position, c'est le renvoi 11 qui établit la 

 <Desc/Clms Page number 2> 

 liaison entre la roue de couronne 8 et les mobiles 13 et 14 de minuterie, c'est-à-dire de mise à l'heure. 



  L'oscillation de la bascule 9 est obtenue à    partir   de la tige de remontoir, agissant sur la tirette 15, susceptible d'occuper deux positions sous l'action d'un levier à crans 16 sollicité par un ressort 17, une goupille 18 de la tirette agissant à son tour sur le bord de la bascule 9, soumise elle-même à l'action d'un ressort de rappel non représenté. 



  On voit que, grâce à cette disposition, la chaîne cinématique reliant la tige de remontoir aux organes de remontage et de mise à l'heure occupe un espace de faible hauteur, voisin du cadran et ne s'opposant plus à loger la masse du rotor à un niveau la faisant passer devant la tige de remontoir, et non plus    au-      dessus   de cette dernière. La pièce en sera naturellement d'autant plus plate, sa hauteur pouvant être réduite en conséquence.

 Timepiece with automatic rotor winding In timepieces with automatic rotor winding, the winding stem and its kinematic connection with the hand-winding and time-setting members occupy a space in outside which moves said rotor or winding mass, which increases the height .de the part and opposes an embodiment of the so-called extra-flat type.



  It has already been proposed to reduce this height by placing the rotor outside the zone of the movement comprising the barrel and the balance. However, this solution has the disadvantage of significantly reducing the radius of gyration of the mass and opposes the profiling in the form of a bell, the thick rim of which constitutes the main source of energy during reassembly.



  In order to be able to use such a profile, the present invention provides that the space swept by the rotor surrounds the entire movement, with the exception of the winding rod, the crown wheel connecting this rod to the movement and a lever being located under the space swept by the rotor, thus offering free passage to its rim.



  The appended drawing shows an embodiment of the object of the invention, given by way of example. Fig. 1 is a semi-schematic view of the part showing the general arrangement adopted.



  Fig. 2 is a half-view of the part on a larger scale, showing the arrangement of the elements for winding and setting the time indicated.



  Fig. 3 is a radial section along the axis of the winding stem, on an even larger scale. In the part semi-schematically represented in FIG. 1, we see a center 1, surrounded by a circle 2. These are the center of the room and its outer perimeter. We see a second center 3, eccentric, surrounded by a circle 4. These are the center of rotation of the mass of the rotor and the outer periphery of the space swept by the latter.



  Due to the fact that the centers 1 and 3 do not coincide, there remains between the space previously mentioned and the external profile of the part a lunula 5. It is in the latter that the winding rod 6 penetrates and is located, which does not can therefore oppose the movements of the rotor.



  The section of FIG. 3 shows, in fact, how this rotor 4 passes in front of the winding stem G and not over it as is usually done, which makes it possible to lower the level of said rotor in the direction of the dial.



  However, this arrangement requires a modified mechanism for transmitting the movements of the winding stem. This mechanism is, for this reason, entirely placed in a plane between the axis of said rod and the dial. Figs. 2 and 3 show it in detail.



  The usual sliding pinion is replaced by a pinion 7 axially fixed and driving the crown wheel 8, on the axis of which oscillates a rocker 9, carrying two deflections 10 and 11. These are constantly engaged with the control wheel. crown 8 but can, depending on the position of lever 9, act either on winding or on time setting.



  In fig. 2, the position shown of the lever and that in solid lines of the references 10 and 11 correspond to winding, the reference 10 establishing the connection between the crown wheel 8 and the ratchet 12. An oscillation of the lever 9 clockwise by compared to fig. 2 would instead bring the references 10 and 11 in the position shown in phantom. In this position, footnote 11 establishes the

 <Desc / Clms Page number 2>

 connection between the crown wheel 8 and the timing wheels 13 and 14, that is to say for setting the time.



  The oscillation of the rocker 9 is obtained from the winding stem, acting on the zipper 15, capable of occupying two positions under the action of a notched lever 16 urged by a spring 17, a pin 18 of the zipper acting in turn on the edge of the lever 9, itself subjected to the action of a return spring, not shown.



  It can be seen that, thanks to this arrangement, the kinematic chain connecting the winding stem to the winding and time-setting members occupies a space of low height, close to the dial and no longer opposing housing the mass of the rotor. at a level making it pass in front of the winding stem, and no longer above the latter. The part will naturally be even more flat, its height can be reduced accordingly.
