Description

La présente invention concerne une pièce d'horlogerie mécanique dont le mouvement, possédant ou non un mécanisme de chronographe, est doté d'un dispositif d'affichage à seconde foudroyante.The present invention relates to a mechanical timepiece, the movement, with or without a chronograph mechanism, has a lightning seconds display device.

Dans un tel dispositif, une aiguille de seconde effectue à vitesse élevée, au dessus du cadran, un tour en une, deux, trois ou quatre secondes, ce tour étant fractionné en plusieurs sauts.In such a device, a second hand performs at high speed, at above the dial, a lap in one, two, three or four seconds, this lap being split into several jumps.

Selon la construction adoptée dans l'art antérieur, l'aiguille de seconde foudroyante est portée par un mobile dont l'arbre comporte un pignon et deux étoiles superposées. Le pignon est en prise avec un train d'engrenage aboutissant à un barillet auxiliaire, différent du barillet principal du mouvement. L'une des étoiles est chassée sur l'arbre, tandis que l'autre est montée libre en rotation et coopère avec une roue de commande chassée sur l'arbre d'une roue d'échappement à ancre entretenant les oscillations d'un organe régulateur, l'échappement et l'organe régulateur (balancier spiral) étant, comme le barillet, dédicacés à la fonction de seconde foudroyante. Typiquement, la roue de commande porte 30 dents et l'étoile libre en porte 4.According to the construction adopted in the prior art, the second hand lightning is carried by a mobile whose shaft has a pinion and two superimposed stars. The pinion is engaged with a gear train ending in an auxiliary barrel, different from the main barrel of the movement. One of the stars is chased on the tree, while the other is freely mounted in rotation and cooperates with a drive wheel driven on the shaft of an anchor escapement wheel supporting the oscillations of a regulator, exhaust and regulator (balance spring) being, like the barrel, dedicated to the function of lightning seconds. Typically, the control wheel carries 30 teeth and the free star carries 4.

Par ailleurs, les deux roues sont accouplées à l'aide d'une goupille solidaire de l'étoile fixe et traversant une ouverture oblongue circulaire pratiquée dans l'étoile libre. Cette goupille limite le déplacement de l'étoile libre afin d'éviter un blocage de la roue de commande.In addition, the two wheels are coupled using an integral pin of the fixed star and passing through an oblong circular opening made in the free star. This pin limits the movement of the free star in order to avoid a locking of the control wheel.

Chaque fois que la roue d'échappement s'arrête sur le repos d'une levée de l'ancre, la roue de commande immobilise l'étoile libre et la libère à l'oscillation suivante. Ainsi, pour une montre battant 14 400 vibrations, à chaque oscillation de son balancier, le pignon sur lequel sont montées l'aiguille et l'étoile fixe font une rotation d'un quart de tour. L'aiguille effectue donc un tour en 4 secondes. Whenever the escape wheel comes to rest on a lift of the anchor, the control wheel immobilizes the free star and releases it to oscillation next. Thus, for a watch beating 14,400 vibrations, each oscillation of its balance, the pinion on which the needle is mounted and the fixed star rotate a quarter turn. The needle therefore makes one revolution in 4 seconds.

Une description plus précise d'un tel mécanisme, particulièrement ingénieux, peut être trouvée dans l'ouvrage intitulé « Montres compliquées » , pages 21 à 26, de François Lecoultre, Editions Horlogères 1951 (Suisse).A more precise description of such a particularly ingenious mechanism, can be found in the book “Complicated Watches”, pages 21 à 26, by François Lecoultre, Editions Horlogères 1951 (Switzerland).

De telles réalisations sont, à l'évidence, particulièrement compliquées, coûteuses et encombrantes puisqu'elles mobilisent, notamment, un barillet, un échappement et un organe régulateur.Obviously, such achievements are particularly complicated, expensive and bulky since they involve, in particular, a barrel, a exhaust and a regulating organ.

La présente invention a pour but de fournir un système d'affichage de seconde foudroyante exempt de ces inconvénients.The object of the present invention is to provide a display system for lightning second free of these drawbacks.

De façon plus précise, l'invention concerne une pièce d'horlogerie mécanique à aiguille de seconde foudroyante, comprenant un barillet, un premier rouage entraíné par le barillet et possédant une roue de minute et une roue de seconde, un échappement actionné par le rouage et un organe régulateur dont les oscillations sont entretenues par ledit échappement, celui-ci comportant une roue d'échappement qui effectue, par sauts, un tour par seconde, au plus. Selon l'invention, pour réaliser la fonction de seconde foudroyante, la pièce comporte seulement un deuxième rouage dont le premier mobile est monté sur l'arbre de la roue d'échappement et dont le dernier mobile est monté sur l'arbre portant l'aiguille de seconde foudroyante.More specifically, the invention relates to a mechanical timepiece with lightning second hand, comprising a barrel, a first gear train driven by the barrel and having a minute wheel and a wheel second, a gear-driven exhaust and a regulating organ whose oscillations are maintained by said exhaust, the latter comprising an escape wheel which performs, by jumps, one revolution per second at most. According to the invention, to perform the second function lightning-fast, the part only has a second gear, the first mobile is mounted on the shaft of the escape wheel and the last mobile is mounted on the shaft carrying the lightning second hand.

La pièce d'horlogerie selon l'invention présente encore les principales caractéristiques suivantes :

  • le deuxième rouage a pour fonction de transmettre à l'aiguille de seconde foudroyante le même mouvement de rotation que la roue d'échappement ;
  • la roue d'échappement effectue 1 tour en 4 secondes ;
  • l'organe régulateur oscille à la fréquence de 5 Hz, l'aiguille de seconde foudroyante effectuant ainsi 1 tour en 4 secondes, à raison de 10 sauts par seconde ;
  • le dernier mobile du deuxième rouage est concentrique à ladite roue de minute ;
  • l'un des mobiles intermédiaires du deuxième rouage est monté sur une bascule actionnable manuellement et susceptible d'occuper une position pour laquelle ledit mobile intermédiaire engrène avec ledit dernier mobile et une position pour laquelle le mobile intermédiaire n'agit pas sur le dernier mobile ;
  • un coeur de remise à zéro est monté sur l'axe portant l'aiguille de seconde foudroyante ;
  • ledit dernier mobile est le premier d'un troisième rouage assurant l'entraínement d'une aiguille de seconde chronométrée et d'une aiguille d'heure ou de minute chronométrée.
The timepiece according to the invention also has the following main characteristics:
  • the second gear has the function of transmitting to the lightning second hand the same rotational movement as the escape wheel;
  • the escape wheel makes 1 revolution in 4 seconds;
  • the regulating organ oscillates at a frequency of 5 Hz, the lightning second hand thus making 1 revolution in 4 seconds, at the rate of 10 jumps per second;
  • the last mobile of the second gear train is concentric with said minute wheel;
  • one of the intermediate moving parts of the second gear train is mounted on a lever which can be actuated manually and capable of occupying a position for which said intermediate moving part meshes with said last moving part and a position for which the intermediate moving part does not act on the last moving part;
  • a reset heart is mounted on the axis carrying the lightning second hand;
  • said last mobile is the first of a third cog ensuring the training of a timed second hand and a timed hour or minute hand.

D'autres caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, sur lequel :

  • la figure 1 représente une première exécution du cadran d'une montre chronographe à seconde foudroyante selon l'invention ;
  • la figure 2 est une vue partielle en coupe selon la ligne AA du mouvement de cette montre ;
  • la figure 3 est une représentation partielle de ce mouvement vu du fond ; enfin,
  • la figure 4 représente une deuxième exécution possible du cadran de la pièce chronographe.
Other characteristics of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  • FIG. 1 represents a first execution of the dial of a chronograph watch with a lightning second according to the invention;
  • Figure 2 is a partial sectional view along line AA of the movement of this watch;
  • Figure 3 is a partial representation of this movement seen from the bottom; finally,
  • FIG. 4 represents a second possible execution of the dial of the chronograph piece.

La pièce d'horlogerie mécanique représentée schématiquement sur les figures 1, 2 et 3 est destinée à afficher, sur un cadran 10, l'heure, la minute, et la seconde du temps courant, mais également l'heure, la seconde et le dixième de seconde du temps chronométré ainsi que le quantième.The mechanical timepiece shown schematically on the Figures 1, 2 and 3 is intended to display, on a dial 10, the hour, the minute, and the second of the current time, but also the hour, the second and the tenth of a second of the time as well as the calendar.

Comme le montre la figure 1, l'heure et la minute du temps courant ainsi que le dixième de seconde du temps chronométré sont affichées au centre de la pièce respectivement par de grandes aiguilles 12, 14 et 16. L'heure et la seconde du temps chronométré, ainsi que la seconde du temps courant, sont affichées respectivement à la position 6 heures par une petite aiguille 18, à la position 3 heures par une petite aiguille 20 et à la position 9 heures par une petite aiguille 22. Enfin, le quantième est affiché par un disque 24 apparaissant derrière une ouverture pratiquée dans le cadran à la position 4 heures et demi.As shown in Figure 1, the hour and minute of the current time as well as the tenth of a second of the timed time are displayed in the center of the piece respectively by large hands 12, 14 and 16. The time and the seconds of the clocked time, as well as the second of the current time, are displayed respectively at the 6 o'clock position by a small hand 18, at the 3 o'clock position with a small hand 20 and at 9 o'clock position with a small hand 22. Finally, the date is displayed by a disc 24 appearing behind an opening in the dial at position 4 and a half hours.

La particularité de cette pièce réside essentiellement dans la manière dont l'aiguille 16 affiche le dixième de seconde du temps chronométré en effectuant 1 tour en 4 secondes, à raison de 10 sauts par seconde. Les autres fonctions d'affichage étant classiques, leur description ne sera pas donnée de manière détaillée.The particularity of this piece lies essentially in the way in which hand 16 displays the tenth of a second of the time measured in performing 1 lap in 4 seconds, at the rate of 10 jumps per second. Others display functions being conventional, their description will not be given in detail.

Ainsi que représenté sur la figure 2, la pièce d'horlogerie selon l'invention comporte, sous son cadran 10, un mouvement qui comprend un bâti formé d'une platine 26 et de ponts 28, servant, de manière classique, au positionnement des mobiles.As shown in Figure 2, the timepiece according to the invention comprises, under its dial 10, a movement which comprises a frame formed a plate 26 and bridges 28, serving, in a conventional manner, to positioning of mobiles.

L'axe sur lequel est fixée l'aiguille de la seconde courante 22 porte une roue de seconde 30 entraínée, comme cela est connu, à raison d'1 tour par minute, par le rouage de finissage du mouvement. Cette roue est en prise avec le pignon de la roue 32 d'un échappement à ancre (non représenté en totalité) et effectue 1 tour en 4 secondes. L'échappement entretient les oscillations d'un organe régulateur constitué d'un balancier spiral (non représenté) oscillant à 5 Hz ou 36000 alternances, soit 10 alternances par seconde. Ainsi, la roue d'échappement 32 tourne en effectuant 10 sauts par seconde.The axis on which the hand of the second current 22 is fixed carries a wheel 30 seconds driven, as is known, at a rate of 1 revolution per minute, by the gear train of the movement. This wheel is engaged with the pinion of the wheel 32 of an anchor escapement (not shown in full) and performs 1 turn in 4 seconds. The exhaust maintains the oscillations of a regulating member consisting of a balance spring (not shown) oscillating at 5 Hz or 36,000 vibrations, or 10 vibrations per second. So the wheel exhaust 32 rotates making 10 jumps per second.

Comme représenté à la fois sur les figures 2 et 3, l'arbre de la roue d'échappement 32 porte, côté fond, une première roue 34 engrenant avec une deuxième roue 36 identique à la première et montée sur le même arbre qu'une roue 38 de plus grand diamètre. Celle-ci, qui effectue ainsi également 1 tour en 4 secondes, engrène avec une roue d'embrayage 40 montée sur une bascule 42, pivotant autour d'un axe 44 et actionnable par une roue à colonnes 46 commandée par un mécanisme classique de chronographe qui ne sera donc pas décrit en détail.As shown in both Figures 2 and 3, the wheel shaft exhaust 32 carries, bottom side, a first wheel 34 meshing with a second wheel 36 identical to the first and mounted on the same shaft than a wheel 38 of larger diameter. This, which thus also performs 1 turn in 4 seconds, meshes with a clutch wheel 40 mounted on a rocker 42, pivoting about an axis 44 and actuable by a wheel columns 46 controlled by a classic chronograph mechanism which will therefore not be described in detail.

La roue à colonnes 46 permet de placer la bascule 42 dans deux positions. Dans celle qui est représentée à la figure 3, pour laquelle la fonction chronographe est enclenchée, la roue d'embrayage 40 engrène avec une roue centrale de chronographe 48 de même diamètre que la roue 38 et coaxiale aux aiguilles 12, 14 et 16. Dans l'autre position, non représentée, pour laquelle la fonction chronographe n'est pas activée, la roue d'embrayage 40 n'agit pas sur la roue centrale 48.The column wheel 46 makes it possible to place the rocker 42 in two positions. In the one shown in Figure 3, for which the function the chronograph is engaged, the clutch wheel 40 meshes with a central chronograph wheel 48 of the same diameter as wheel 38 and coaxial with needles 12, 14 and 16. In the other position, not shown, for which the chronograph function is not activated, the clutch wheel 40 does not act on the central wheel 48.

Ainsi, la roue 48 effectue également 1 tour en 4 secondes à raison de 10 sauts par seconde. Cette roue est fixée sur un axe 50 portant l'aiguille 16 qui permet donc d'afficher le dixième de seconde sur le cadran 10.Thus, the wheel 48 also makes 1 revolution in 4 seconds at the rate of 10 jumps per second. This wheel is fixed on an axis 50 carrying the needle 16 which therefore displays the tenth of a second on dial 10.

Comme cela est le cas pour tout chronographe, l'axe 50 porte un coeur 52 pour la remise à zéro de l'aiguille 16. De manière connue également, cet axe est, par ailleurs, au centre d'un mécanisme d'entraínement des aiguilles d'heure 12 et de minute 14 à partir d'une roue de minute 54 coopérant avec la roue de seconde 30 par l'intermédiaire d'une roue de moyenne non représentée.As is the case with any chronograph, the axis 50 carries a heart 52 for resetting the needle to zero 16. Also in a known manner, this axis is, moreover, at the center of a needle drive mechanism hour 12 and minute 14 from a minute wheel 54 cooperating with the 30 second wheel via a mean wheel no represented.

Enfin, pour compléter la fonction chronographe, la roue centrale 48 constitue, de façon tout à fait classique, le premier mobile d'un train d'engrenage assurant l'entraínement de l'aiguille de seconde 20 et de l'aiguille d'heure 18. Bien entendu, l'affichage de l'heure chronométrée, réalisé par cette aiguille, peut être remplacé par un affichage de la minute chronométrée.Finally, to complete the chronograph function, the central wheel 48 constitutes, in a completely classic way, the first mobile of a gear train ensuring the driving of the second hand 20 and the hour hand 18. Of course, the display of the timed time, produced by this hand, can be replaced by a display of the timed minute.

La présente description a été faite en se référant essentiellement à une pièce dotée d'une aiguille de seconde foudroyante à 9 heures et d'une grande aiguille de seconde courante. Il va de soi que d'autres réalisations sont possibles sans sortir du cadre de l'invention. C'est ainsi, par exemple, que comme montré à la figure 4, l'aiguille de seconde foudroyante 16 peut être placée à 9 heures et remplacée, au centre, par l'aiguille de seconde courante 22.This description has been made with reference essentially to a part with a lightning seconds hand at 9 o'clock and a large current second hand. It goes without saying that other achievements are possible without departing from the scope of the invention. This is how, for example, as shown in figure 4, the lightning second hand 16 can be placed at 9 o'clock and replaced, in the center, by the current second hand 22.

Ainsi est proposée une pièce d'horlogerie qui affiche la seconde foudroyante sans utiliser, notamment, un barillet, un échappement et un organe régulateur spécialement à cette fonction.Thus is proposed a timepiece which displays the lightning second without using, in particular, a barrel, an exhaust and a regulating member specially for this function.
