Description
Mecanisme de remontoir et de mixe ä Pheure ä bascule pour mouvement de montre. La präsente Invention a pour objet un meeanisme de remontoir et de mise ä 1'heure ä, bascule pour mouvement de montre. Celle-ei peut etre eta.nche ou non etanche. Winding and tilting hour mechanism for watch movement. The subject of the present invention is a mechanism for winding and setting the time with rocker for a watch movement. This may or may not be watertight.
Jusqu'ä. präsent, 1'emploi d'un mecanisme ä bascule dann les montres etanches presen- tait 1'inconvenient suivant: Quand an presse la couronne de remontoir pour passer de la Position de mise ä Pheure ä la Position de remontage, la baseule tend ä revenir dann la Position de remontage sous 1'action du ressort de bascule. Comme, dans les montres etanches, la couronne de remontoir äst retenue par un paquetage d'etancheite et que 1e grand renvoi se trouve ainsi immobilise, 1e r envoi de mise ä 1'heure, pivote Sur la baseule, tend ä rouler ä la facon d'un satellite Sur 1e grand renvoi lors du retour de la baseule ä sa Position nor male de remontage. Ceci a pour äffet que 1e renvoi de mise ä 1'heure tend ä tourner Sur son axe, de Sorte que, ou bien la bascule reste dann la Position de mise ä 1'heure, ou bien, au debut du retour de la bascule, 1e renvoi de mixe A, 1'heure entraine la roue de minute- rie et fait legerement tourner les aiguilles de la montre. Until. At present, the use of a rocker mechanism in waterproof watches had the following drawback: When one presses the winding crown to pass from the Time-Setting Position to the Winding Position, the base in the winding position under the action of the toggle spring. As, in water-resistant watches, the winding crown is retained by a water-resistance package and the large transmission is thus immobilized, the 1st time-setting transmission pivots on the base, tending to roll of a satellite On the large transmission during the return of the baseule to its normal winding position. This has the effect that the time-setting gear tends to rotate on its axis, so that either the rocker remains in the time-setting position, or, at the start of the rocker's return, the 1st gear A, the hour drives the timer wheel and causes the hands of the watch to turn slightly.
0n a dejä tente de remedier ä cet ineon- v6nient en munissant les roues du mecanisme de dentures speeiales ä developpante de cercle, mais ces solutions avaient des desavantages serieux au point de vue de la fabrication, du prix de revient, des Pressions Sur les axes, etc. Attempts have already been made to remedy this inconvenience by providing the wheels of the mechanism with special involute toothing, but these solutions had serious disadvantages from the point of view of manufacture, cost price, pressures on the axes. , etc.
L'invention a pour but de fournir une solution rationelle ä c0 Probleme. Le m6ca- nisme qui en fait 1'objet äst caraeterise en ce que 1e carre de la tige de remontoir äst con- forme de telle maniere que, lors du retour de la tige de remontoir de la Position de mise ä. 1'heure ä la Position de remontage, 1e renvoi de mise ä 1'heure, pivote Sur la bascule, ne puisse pas agir Sur les aiguilles de la montre, ni empecher 1e retour de la bascule. The invention aims to provide a rational solution to this problem. The mechanism which is the subject of this is characterized in that the square of the winding stem conforms in such a way that, when the winding stem returns from the setting position. the time in the winding position, the 1st time-setting reference pivots on the rocker, cannot act on the hands of the watch, nor prevent the rocker from returning.
Le dessin annexe montre, ä titre d'exem- ple, deux formes d'exectltion du meeanisme suivant 1'invention. The accompanying drawing shows, by way of example, two embodiments of the mechanism according to the invention.
La fig. 1 äst une vue en plan de la Pre miere forme d'execution, et la fig. 2 montre la tige de remontoir de la seconde. fig. 1 is a plan view of the first embodiment, and FIG. 2 shows the second winding stem.
La bascule 1 pivotant Sur la vis ä portee 2 Porte 1e renvoi de mise ä 1'heure 3 et 1e ren- voi de remontage 4. Dans la Position de la bascule dessinee en traits pleins, 1e renvoi de remontage 4 engrene avec 1e rochet de baril- let 5, tandis que 1e renvoi de mixe ä 1'heure 3 äst hörs de Prise d'avec la roue de minuterie 6. Dans la Position de la bascule 1 dessinee en traits mixtes, Ast Pinverse. RTI ID="0001.0268" WI="4" HE="4" LX="1495"LY="1898"> Le grand renvoi 7, pivotant coaxialement ä la bascule 1, äst constamment en Prise avec les renvois 3 et 4 et avec 1e pignon de remontoir B. La tige de remontoir 9 präsente un carre 10 de forme helicoidale. Ce carre traverse un trou 11, de forme correspondante, pratique dann 1e pignon de remontoir B. Ce trou pourrait aussi bien präsenter des parois planes. Un ressort de bascule 12 tend ä maintenir la baseule 1 dans la position normale de remontage. Lorsqu'on tire la couronne 13 dans la position de mise à l'heure, la tirette 1.1, dont. le plot. s'engage dans une gorge de la tige 9 et qui est sous l'action d'un sautoir 15, fait tourner la bas cule 1 dans le sens des aiguilles d'une montre et amène le renvoi 3 en prise avec la roue 6. Rocker 1 pivoting On bearing screw 2 Carries 1st time-setting gear 3 and 1st winding gear 4. In the position of the rocker drawn in solid lines, 1st winding gear 4 meshes with the barrel 5, while the 1st mixing gear at hour 3 is out of engagement with timer wheel 6. In position of rocker 1 drawn in phantom, Ast reverses it. RTI ID="0001.0268" WI="4" HE="4" LX="1495"LY="1898"> The large reference 7, pivoting coaxially with the rocker 1, is constantly in Engagement with the references 3 and 4 and with the first winding pinion B. The winding stem 9 has a square 10 of helical shape. This edge passes through a hole 11, of corresponding shape, practical in the first winding pinion B. This hole could just as well have flat walls. A rocker spring 12 tends to maintain the base 1 in the normal winding position. When the crown 13 is pulled into the time-setting position, the pull tab 1.1, of which. the plot. engages in a groove of the rod 9 and which is under the action of a jumper 15, rotates the stocking 1 clockwise and brings the transmission 3 into engagement with the wheel 6.
Lorsqu'on abaisse la couronne 13 dans la position de remontage, la tirette 14 revient dans la position dessinée et permet à la bas cule 1 de tourner en sens inverse des aiguilles d'une montre sous l'action de son ressort 12. Lors du mouvement de la tige 9, son carré hélicoïdal 10 communique au pignon 8 un #nouvement de rotation qui fait tourner le grand renvoi 7 dans le sens de la flèche r1. Par suite, le renvoi 3 est entraîné dans le sens de la flèche B. Simultanément, la bascule 1 retourne dans sa position normale et fait rouler le renvoi 3 sur le grand renvoi 7, de sorte que le renvoi 3 tourne autour de son axe dans le sens de la flèche C. Le pas du carré hélicoïdal 10 est choisi de telle façon que les deux rotations du renvoi 3 dans le sens des flèches B et C se compensent. De cette façon, l'absence de réaction du grand renvoi 7 em pêche toute transmission de force du renvoi 3 à la roue de minuterie 6. La bascule 1 est donc libre de reprendre sa position normale et la -oue de minuterie 6 ne saurait être actionnée intempestivement. When the crown 13 is lowered into the winding position, the pull tab 14 returns to the position drawn and allows the bottom 1 to rotate counterclockwise under the action of its spring 12. movement of the rod 9, its helical square 10 communicates to the pinion 8 a nouvement of rotation which rotates the large reference 7 in the direction of the arrow r1. As a result, the reference 3 is driven in the direction of the arrow B. Simultaneously, the rocker 1 returns to its normal position and causes the reference 3 to roll on the large reference 7, so that the reference 3 rotates around its axis in the direction of the arrow C. The pitch of the helical square 10 is chosen so that the two rotations of the transmission 3 in the direction of the arrows B and C compensate each other. In this way, the absence of reaction from the large reference 7 prevents any transmission of force from the reference 3 to the timer wheel 6. The rocker 1 is therefore free to resume its normal position and the timer wheel 6 cannot be accidentally activated.
Dans la forme d'exécution qui vient d'être décrite, le grand renvoi 7 est positivement entraîné en rotation quand on abaisse la cou ronne 13. En revanche, dans la forme d'exé eution de la fig. 2, l'abaissement de la. cou ronne 13 donne au grand renvoi 7 la possi bilité de tourner librement d'un petit angle, ce qui permet. d'obtenir le même résultat. Le carré 16 de la tige de remontoir 9 a la forme d'une pyramide tronquée dont la petite base se trouve du côté de la couronne 13. Grâce à cette forme du carré 16, quand on abaisse la couronne, le pignon de remontoir 8 acquiert un certain jeu par rapport au carré 16, de sorte que le grand renvoi 7 est libre de tour ner quelque peu. Lorsque la bascule revient dans sa, position normale, l'absence de réac tion du grand renvoi 7 empêche toute trans mission de force du renvoi 3 à, la. roue de minuterie 6. Les aiguilles de la. montre restent. donc immobiles et la bascule 1 peut retourner avec sécurité dans la position de remontage. In the form of execution which has just been described, the large reference 7 is positively driven in rotation when the crown 13 is lowered. On the other hand, in the form of execution of FIG. 2, the lowering of the. crown 13 gives the large reference 7 the possibility of rotating freely through a small angle, which allows. to obtain the same result. The square 16 of the winding stem 9 has the shape of a truncated pyramid whose small base is on the side of the crown 13. Thanks to this shape of the square 16, when the crown is lowered, the winding pinion 8 acquires a certain play with respect to the square 16, so that the large reference 7 is free to turn somewhat. When the rocker returns to its normal position, the absence of reaction from the large reference 7 prevents any transmission of force from the reference 3 to, the. timer wheel 6. The hands of the. shows remain. therefore immobile and rocker 1 can safely return to the winding position.
