Definitions
- the present invention relates to a mechanical movement watch whose escapement is driven through a constant force device.
- the term "constant force deviceā has been used for more than a century to designate a member interposed in the gear train connecting the mainspring to the exhaust and comprising a permanently loaded intermediate spring, in order to to transmit a relatively constant torque to the escapement, corresponding to the tension of the intermediate spring.
- This tension oscillates somewhat, but in a small margin and its average value remains constant over the hours.
- the variations in the state of armature of the mainspring do not vary the forces applied to the mechanical oscillator, whose amplitude and frequency are then more stable.
- the constant force device temporarily blocks the part of the wheel train upstream, then a periodic release that retension the intermediate spring.
- the rate of deblocking is once per second and this makes it possible to blow at this rate a second indicator hand, commonly called "second dead".
- Constant force devices are thus almost always combined with the seconds wheel, with a second dead display.
- Various examples of such combinations and their operation are described in patent publications CH 47 297 , CH 98 828 , CH 120 028 , EP 1 319 997 and EP 1,528,443 .
- the last cited publication further provides that the regulator member driven by the constant force device may be a vortex, which is integral with the output wheel of the constant force device.
- the mechanism for stopping and releasing the dead-second device periodically must be controlled from the wheel that follows the seconds wheel, and therefore the escape wheel.
- the first organ undergoing blockage is usually called a "whip", because at the moment it is released, it performs a very fast rotation over a complete revolution or a fraction of a turn, until it is again blocked.
- the element that blocks the whip is usually an N-shaped star, making a turn in N seconds to release the whip once a second.
- this star is integral with the escape wheel, because it runs at a speed (one turn in six seconds) which corresponds to an acceptable number of branches of the star.
- Instant rotation and consecutive sudden stop are accompanied by all the gear located upstream and by the display members associated therewith.
- the present invention aims at avoiding the above-mentioned drawbacks of the prior art by providing a watch movement with a constant-force device whose instantaneous movements disturb as little as possible the operating conditions of the escapement and the mechanical oscillator. .
- An additional object is to be able to drive a vortex in good conditions with such a constant-force device.
- the exhaust thus receives a motor torque as constant as possible.
- the watch comprises a display said dead minute, by a minute hand driven by the finishing train, the number of branches of the star being equal to the number of minutes during which the The star makes a turn, so that the rotation of the star releases the cogwheel, the moving average and the minute hand once a minute.
- the fact that the minute hand jumps from one division to the next on the minute scale of the watch dial provides an unprecedented visual effect and makes it easier to read the time.
- a spring barrel 2 rotates the pinion 3 of an intermediate wheel 4, called the wheel of eight, which meshes with the center pinion 5 of a center wheel 6 making one turn per hour.
- the presence of the intermediate wheel 4 in this example is not directly related to the invention; it is due to the fact that the movement 1 comprises several unrepresented complications to be driven by the barrel 2, which is provided with a longer spring and rotates faster than ordinary barrels.
- the winding of the mainspring can be manual or automatic.
- a carriage carrying a minute hand 7 is frictionally mounted on the shaft 8 of the center wheel 6 and rotatably supports a hour wheel carrying a 9 hour hand.
- the hands of this time display device are shown in the drawings, and this very schematically.
- the center wheel 6 meshes with the pinion 11 of a mobile of average 12 comprising a first average wheel 13.
- the mobile 12 is associated with the constant-force device 14 shown in detail in FIGS. Figures 3 and 4 .
- the mobile 12, having an axis of rotation 15, further comprises a plate 16 having a short tubular shaft (not visible in the drawings) which is mounted by a bearing 17 in a bridge 18 and driven into the central hole of the wheel 13
- the mobile 12, being driven by the couple motor provided by the barrel 2 forms the input element of the constant-force device 14.
- a second average wheel 20, forming the output element of the constant-force device 14, is coaxial with the first average wheel 13, this wheel 20 being fixed on a shaft 21 rotatably mounted at the center of the mobile 12.
- a spiral spring 22 is placed between the plate 16 and the wheel 20, which connects one to the other in rotation in an elastic manner, the inner end of the spring being fixed in a hole 24 of a branch of the wheel 20, while the outer end of the spring is fixed to the plate 16.
- An eight-pointed star 26 is attached to the upper end of the shaft 21, which further comprises a pivot 27 supported by a bearing in a bridge 28.
- the star 26 serves as a locking member for a gear train. stopping 30 driven by the first medium wheel 13. Indeed, it meshes with a pinion 31 of a shaft 32 rotatably mounted in the bridges 18 and 28 and provided with a wheel 33 above the
- the stop gear 30 terminates with a stop wheel 35 driven by the wheel 33 through a deflection wheel 34 to rotate in the opposite direction to the star.
- the wheels 34 and 35 are supported by the bridge 28.
- the wheel 35 is provided with an off-center finger 36 which abuts successively against each branch of the star 26 during the rotation thereof, as the whip of the devices of the prior art. As long as the star thus prevents the rotation of the wheel 35 and thus the stop gear 30, the rotation of the first medium wheel 13 and all the previous wheel is stopped.
- the rotations of the elements of the movement 1 are effected in the directions indicated by arrows in the figure 1 .
- the rate of rotation is that of the escape wheel contained in the vortex, for example six steps per second if the oscillation frequency of the balance 42 is 3 Hz.
- Upstream of the constant-force device intermittent rotations occur at one step per minute for the following reasons.
- the number of branches of the star 26 could be different from eight if the transmission ratio between the second average wheel 20 and the second gear 38 is different.
- the star is not necessarily secured to the wheel 20, to which it could be connected by meshing to be placed next to and cooperate with a finger placed on the wheel 33, for example.
- Another variant could include more than one finger 36 on the stop wheel 35, which would be only a fraction of a turn every minute.
- the invention is applicable without difficulty to a movement of the type where the roadway is not carried by the center wheel 6, but by a wheel driven by the average gear, as is the usual practice. with a tree of the second central.

Abstract
Description
La prĆ©sente invention concerne une montre Ć mouvement mĆ©canique dont l'Ć©chappement est entraĆ®nĆ© Ć travers un dispositif Ć force constante.The present invention relates to a mechanical movement watch whose escapement is driven through a constant force device.
Dans l'horlogerie mĆ©canique, l'expression Ā« dispositif Ć force constante Ā» est utilisĆ©e depuis plus d'un siĆØcle pour dĆ©signer un organe interposĆ© dans le rouage reliant le ressort moteur Ć l'Ć©chappement et comportant un ressort intermĆ©diaire chargĆ© en permanence, afin de transmettre Ć l'Ć©chappement un couple relativement constant, correspondant Ć la tension du ressort intermĆ©diaire. Cette tension oscille quelque peu, mais dans une faible marge et sa valeur moyenne reste constante au fil des heures. Ainsi, les variations de l'Ć©tat d'armage du ressort moteur ne font pas varier les forces appliquĆ©es Ć l'oscillateur mĆ©canique, dont l'amplitude et la frĆ©quence sont alors plus stables.In mechanical watchmaking, the term "constant force device" has been used for more than a century to designate a member interposed in the gear train connecting the mainspring to the exhaust and comprising a permanently loaded intermediate spring, in order to to transmit a relatively constant torque to the escapement, corresponding to the tension of the intermediate spring. This tension oscillates somewhat, but in a small margin and its average value remains constant over the hours. Thus, the variations in the state of armature of the mainspring do not vary the forces applied to the mechanical oscillator, whose amplitude and frequency are then more stable.
Le dispositif Ć force constante effectue un blocage temporaire de la partie du rouage situĆ©e en amont, puis un dĆ©blocage pĆ©riodique qui permet de retendre le ressort intermĆ©diaire. En gĆ©nĆ©ral, la cadence de dĆ©blocage est d'une fois par seconde et cela permet de faire sauter Ć ce rythme une aiguille indicatrice des secondes, appelĆ©e couramment Ā« seconde morte Ā». Les dispositifs Ć force constante sont donc presque toujours combinĆ©s Ć la roue des secondes, avec un affichage Ć seconde morte. DiffĆ©rents exemples de telles combinaisons et leur fonctionnement sont dĆ©crits dans les publications de brevets
Le mĆ©canisme d'arrĆŖt et dĆ©blocage pĆ©riodique du dispositif Ć seconde morte doit ĆŖtre commandĆ© Ć partir de la roue qui suit la roue des secondes, donc la roue d'Ć©chappement. Le premier organe subissant le blocage est gĆ©nĆ©ralement appelĆ© Ā« fouet Ā», parce qu'Ć l'instant oĆ¹ il est libĆ©rĆ©, il effectue une rotation trĆØs rapide sur un tour complet ou une fraction de tour, jusqu'Ć ce qu'il soit Ć nouveau bloquĆ©. L'Ć©lĆ©ment qui bloque le fouet est gĆ©nĆ©ralement une Ć©toile Ć N branches, faisant un tour en N secondes afin de libĆ©rer le fouet une fois par seconde. Typiquement, comme le montre le brevet
La prĆ©sente invention vise Ć Ć©viter les inconvĆ©nients susmentionnĆ©s de l'art antĆ©rieur, en dotant un mouvement de montre d'un dispositif Ć force constante dont les mouvements instantanĆ©s perturbent le moins possible les conditions de fonctionnement de l'Ć©chappement et de l'oscillateur mĆ©canique. Un but additionnel est de pouvoir entraĆ®ner un tourbillon dans de bonnes conditions avec un tel dispositif Ć force constante.The present invention aims at avoiding the above-mentioned drawbacks of the prior art by providing a watch movement with a constant-force device whose instantaneous movements disturb as little as possible the operating conditions of the escapement and the mechanical oscillator. . An additional object is to be able to drive a vortex in good conditions with such a constant-force device.
Dans ce but, l'invention concerne une montre telle que dƩfinie par la revendication 1 du brevet.For this purpose, the invention relates to a watch as defined by
Ainsi, les chocs causĆ©s par le fouet constituĆ© par le doigt du rouage d'arrĆŖt, lorsqu'il bute contre l'Ć©toile, ne se rĆ©percutent pratiquement pas dans l'Ć©chappement, car il existe un engrenage Ć fort rapport de multiplication entre l'Ć©lĆ©ment de sortie du dispositif Ć force constante et la roue d'Ć©chappement, avec un mobile intermĆ©diaire qui est le mobile des secondes. L'Ć©chappement reƧoit donc un couple moteur aussi constant que possible.Thus, the shocks caused by the whip formed by the finger of the stop train, when it abuts against the star, do not substantially affect the exhaust, because there is a gear with a high multiplication ratio between the output element of the constant force device and the escape wheel, with an intermediate mobile which is the mobile seconds. The exhaust thus receives a motor torque as constant as possible.
Selon un mode de rĆ©alisation prĆ©fĆ©rĆ© de l'invention, la montre comporte un affichage dit Ć minute morte, par une aiguille des minutes entraĆ®nĆ©e par le rouage de finissage, le nombre de branches de l'Ć©toile Ć©tant Ć©gal au nombre de minutes durant lesquelles l'Ć©toile fait un tour, de sorte que la rotation de l'Ć©toile libĆØre le rouage d'arrĆŖt, le mobile de moyenne et l'aiguille des minutes une fois par minute. Le fait que l'aiguille des minutes saute ainsi d'une division Ć la suivante sur l'Ć©chelle des minutes du cadran de la montre procure un effet visuel inĆ©dit et facilite la lecture de l'heure.According to a preferred embodiment of the invention, the watch comprises a display said dead minute, by a minute hand driven by the finishing train, the number of branches of the star being equal to the number of minutes during which the The star makes a turn, so that the rotation of the star releases the cogwheel, the moving average and the minute hand once a minute. The fact that the minute hand jumps from one division to the next on the minute scale of the watch dial provides an unprecedented visual effect and makes it easier to read the time.
On notera Ć©galement que dans le cas oĆ¹ la montre comprend un mĆ©canisme de tourbillon, l'arrangement de l'invention du dispositif sur la minute permet de le disposer aisĆ©ment Ć l'extĆ©rieur du mĆ©canisme de tourbillon,Note also that in the case where the watch comprises a vortex mechanism, the arrangement of the invention of the device on the minute makes it easy to arrange it outside the vortex mechanism,
D'autres caractĆ©ristiques et avantages de la prĆ©sente invention ressortiront de la description suivante, qui prĆ©sente un mode de rĆ©alisation avantageux Ć titre d'exemple non limitatif en se rĆ©fĆ©rant aux dessins annexĆ©s, dans lesquels :

Dans le mouvement de montre 1 reprĆ©sentĆ© de maniĆØre simplifiĆ©e dans les
La roue de centre 6 s'engrĆØne sur le pignon 11 d'un mobile de moyenne 12 comprenant une premiĆØre roue moyenne 13. Le mobile 12 est associĆ© au dispositif Ć force constante 14 reprĆ©sentĆ© en dĆ©tail dans les
Une Ć©toile 26 Ć huit branches 25 est fixĆ©e Ć l'extrĆ©mitĆ© supĆ©rieure de l'arbre 21, qui comporte en outre un pivot 27 supportĆ© par un palier dans un pont 28. L'Ć©toile 26 sert d'organe de blocage pour un rouage d'arrĆŖt 30 entraĆ®nĆ© par la premiĆØre roue moyenne 13. En effet, celle-ci s'engrĆØne sur un pignon 31 d'un arbre 32 montĆ© de maniĆØre rotative dans les ponts 18 et 28 et muni d'une roue 33 au-dessus du niveau de la roue 20. Le rouage d'arrĆŖt 30 se termine par une roue d'arrĆŖt 35 entraĆ®nĆ©e par la roue 33 par l'entremise d'une roue de renvoi 34 afin de tourner dans le sens opposĆ© Ć l'Ć©toile. Les roues 34 et 35 sont supportĆ©es par le pont 28. La roue 35 est munie d'un doigt dĆ©centrĆ© 36 qui bute successivement contre chaque branche de l'Ć©toile 26 pendant la rotation de celle-ci, comme le fouet des dispositifs de l'art antĆ©rieur. Tant que l'Ć©toile empĆŖche ainsi la rotation de la roue 35 et donc du rouage d'arrĆŖt 30, la rotation de la premiĆØre roue moyenne 13 et de tout le rouage prĆ©cĆ©dent est arrĆŖtĆ©e.An eight-
La seconde roue moyenne 20 s'engrĆØne sur un pignon de secondes 38 qui fait un tour par minute et qui, dans le prĆ©sent exemple, est fixĆ© Ć la cage 41 d'un tourbillon 40 contenant de maniĆØre classique l'Ć©chappement et l'oscillateur mĆ©canique Ć balancier-spiral, dont on voit le balancier 42 centrĆ© sur l'axe de rotation 44 de la cage 41. Celle-ci peut porter une aiguille des secondes 45, comme le montre schĆ©matiquement la
Lors de l'assemblage du dispositif Ć force constante 14, les positions relatives du plateau 16 et de la roue 20 sont fixĆ©es au moyen du rouage d'arrĆŖt 30 de faƧon que le ressort spiral 22 soit prĆ©chargĆ© avec le couple souhaitĆ© pour faire fonctionner de maniĆØre optimale l'organe rĆ©gulateur du mouvement de montre, en l'occurrence le tourbillon 40. Le ressort 22 a de prĆ©fĆ©rence plusieurs spires, afin que le couple qu'il transmet du mobile 12 Ć la roue 20 ne varie pas sensiblement pendant que cette roue effectue un huitiĆØme de tour alors que le plateau 16 est arrĆŖtĆ©.During the assembly of the
En fonctionnement, les rotations des Ć©lĆ©ments du mouvement 1 s'effectuent dans les directions indiquĆ©es par des flĆØches dans la
Tant que la branche 25 (voir
La construction dĆ©crite ci-dessus et reprĆ©sentĆ©e dans les dessins n'est qu'un exemple parmi d'autres modes de rĆ©alisation possibles de l'invention. En particulier, le nombre de branches de l'Ć©toile 26 pourrait diffĆ©rent de huit si le rapport de transmission entre la seconde roue moyenne 20 et le pignon des secondes 38 est diffĆ©rent. En outre, l'Ć©toile n'est pas obligatoirement solidaire de la roue 20, Ć laquelle elle pourrait ĆŖtre reliĆ©e par engrĆØnement pour ĆŖtre placĆ©e Ć cĆ“tĆ© et coopĆ©rer avec un doigt placĆ© sur la roue 33, par exemple. Une autre variante pourrait comporter plus d'un doigt 36 sur la roue d'arrĆŖt 35, laquelle ne ferait qu'une fraction de tour chaque minute. Il faut aussi mentionner que l'invention est applicable sans difficultĆ©s Ć un mouvement du type oĆ¹ la chaussĆ©e n'est pas portĆ©e par la roue de centre 6, mais par une roue entraĆ®nĆ©e par le pignon de moyenne, comme c'est l'usage avec un arbre des seconde centrale.The construction described above and shown in the drawings is only one of a number of other possible embodiments of the invention. In particular, the number of branches of the
