Abstract

The watch has a second fraction needle driven by a gauge arm. The needle is rotated on a plate whose amplitude of displacement is controlled by arrival of jaw in abutment on a circular blade driven by a chronograph wheel. The blade has elementary blades (22), each corresponding to one second. The blades (22) having same contour determine the displacement of the arm and divide one second into fractions.

Description

La présente invention a pour objet un dispositif permettant l'affichage instantané de fractions de seconde, sur un compteur séparé dans une montre-chronographe mécanique, seulement lorsqu'on arrête le chronométrage, ou lorsqu'on interrompt momentanément le chronométrage lorsque ladite montre-chronographe est pourvue d'une rattrapante.The present invention relates to a device for displaying fractional seconds snapshot, on a separate counter in a chronograph watch mechanical, only when timing is stopped, or when momentarily stops timing when said chronograph watch is with a split-second.

Dans les montres-chronographes à entraínement mécanique, on a généralement une aiguille de secondes centrale entraínée par la roue de chronographe lorsqu'on appuie sur le poussoir start, cette aiguille avançant pas à pas à la fréquence imposée par le balancier-spiral. Si cette fréquence est de 18'000 alternances par heure, l'aiguille avancera de 5 pas par seconde, soit d'un angle de 1,2° par pas. Avec un cadran de l'ordre de 30 mm, cela signifie qu'à chaque pas la pointe de l'aiguille des secondes se déplacera d'un arc d'environ 0,3 mm, longueur qu'il est possible de distinguer à l'oeil nu s'il existe une graduation additionnelle entre chaque seconde. On conviendra toutefois que la lecture d'un temps chronométré à un cinquième de seconde près exige une certaine attention, et que la fiabilité de la lecture dépend aussi du soin avec lequel les graduations ont été produites ou décalquées sur le cadran, ainsi que de la précision avec laquelle les pieds de cadran ont été ajustés.In chronograph watches with mechanical drive, we have generally a central seconds hand driven by the wheel chronograph when you press the start button, this hand advancing step by step at the frequency imposed by the balance spring. If this frequency is 18,000 vibrations per hour, the hand will advance 5 steps per second, or by an angle of 1.2 ° per step. With a dial of the order of 30 mm, this means that at each step the tip of the second hand will move in an arc of about 0.3 mm, length that it is possible to distinguish with the naked eye if there is an additional graduation between each second. It should however be agreed that the reading of a time timed at a fifth of a second requires some attention, and that the reliability of the reading also depends on the care with which the graduations were produced or transferred onto the dial, as well as the precision with which the dial feet have been adjusted.

Pour pallier les inconvénients ci-dessus, les constructeurs ont proposé d'équiper les montres-chronographes mécaniques d'un dispositif dit "à seconde foudroyante". Le principe consiste à afficher sur le cadran les fractions de seconde sur un compteur séparé au moyen d'une petite aiguille, entraínée en permanence par un train multiplicatif d'engrenages, ladite petite aiguille faisant chaque seconde un tour complet, voire 4 ou 5 tours selon la complexité du train d'engrenages. Un tel dispositif rend la lecture plus facile, et permet d'avoir une précision au dixième de seconde, mais a l'inconvénient d'exiger un surplus d'énergie mécanique pour entraíner pendant le temps de chronométrage le train d'engrenages et la petite aiguille. Cette ressource supplémentaire en énergie peut être obtenue en augmentant les dimensions du barillet, ou en ajoutant un deuxième barillet, ce qui a comme inconvénient de rendre la construction du mouvement plus complexe, et d'augmenter le poids et les dimensions de la montre-chronographe.To overcome the above drawbacks, the manufacturers have proposed to equip mechanical chronograph watches with a device known as "second overwhelming ". The principle is to display fractions of a second on the dial on a separate counter by means of a small needle, permanently driven by a multiplying gear train, said small needle making one revolution every second complete, even 4 or 5 turns depending on the complexity of the gear train. Such a device makes reading easier, and allows precision to the tenth of a second, but has the disadvantage of requiring a surplus of mechanical energy to train for the timing time the gear train and the small hand. This resource additional energy can be obtained by increasing the dimensions of the barrel, or by adding a second barrel, which has the disadvantage of making the building more complex movement, and increasing the weight and dimensions of the chronograph watch.

Lorsque la montre-chronographe permet d'effectuer des chronométrages intermédiaires, l'arrêt de la rattrapante n'arrête pas la foudroyante, de sorte que la lecture d'un temps intermédiaire n'a pas la précision du temps lu après l'arrêt complet du chronométrage.When the chronograph watch allows timing intermediaries, stopping the split-second does not stop the lightning, so that the reading an intermediate time does not have the precision of the time read after the complete stop timing.

L'invention vise donc à pallier les inconvénients de l'art antérieur précité en procurant une montre-chronographe mécanique comportant un mécanisme permettant d'afficher instantanément, après avoir arrêté temporairement ou définitivement le chronométrage, les fractions de secondes à ajouter aux valeurs indiquées par la rattrapante ou l'aiguille de seconde au centre et par les autres compteurs. Pendant toute la durée du chronométrage le dispositif selon l'invention est conçu pour que le compteur affichant les fractions de seconde soit totalement désolidarisé de la chaíne cinématique, ce qui présente l'avantage de réduire considérablement l'apport d'énergie mécanique qui était nécessaire selon l'art antérieur précité, tout en procurant un affichage ayant une excellente précision et une excellente lisibilité, tant pour un temps final que pour des temps intermédiaires.The invention therefore aims to overcome the drawbacks of the aforementioned prior art in providing a mechanical chronograph watch with a mechanism allowing to display instantly, after having temporarily stopped or definitive timing, fractions of seconds to add to the values indicated by the split-seconds or the second hand in the center and by the others counters. Throughout the timing, the device according to the invention is designed so that the counter displaying fractions of a second is completely disconnected from the kinematic chain, which has the advantage of reducing considerably the contribution of mechanical energy which was necessary according to art above, while providing a display having excellent accuracy and excellent readability, both for a final time and for intermediate times.

A cet effet, l'invention concerne une montre-chronographe comportant un mouvement de chronographe avec une base de temps de fréquence F, des moyens de commande pour la mise en marche, l'arrêt et la remise à zéro du chronométrage, un cadran à affichage analogique au moyen d'une aiguille de secondes au centre, et éventuellement une aiguille de rattrapante, entraínée par la roue de chronographe qui entraíne également par l'intermédiaire de trains d'engrenages les aiguilles d'autres compteurs et une aiguille d'un compteur comportant une graduation en fractions de secondes. La montre-chronographe est caractérisée en ce que l'aiguille de fractions de seconde reste immobile pendant toute la durée du chronométrage et qu'elle est entraínée en rotation, lorsqu'on arrête, temporairement ou définitivement, le chronométrage, par un bras palpeur pivoté sur une platine ou un pont du mouvement, dont le basculement est déclenché par les moyens d'arrêt du chronographe et dont l'amplitude du débattement est contrôlée par l'arrivée de son bec en butée sur une came circulaire. La came circulaire est entraínée par la roue de chronographe et comporte x cames élémentaires d'ouverture angulaire α correspondant chacune à un nombre entier de secondes diviseur de 60. Toutes les cames élémentaires ont un même contour qui détermine l'amplitude du débattement du bras palpeur et donc le déplacement de l'aiguille du compteur de fractions de seconde en face d'une graduation déterminée, le fractionnement de la seconde étant fonction de la fréquence F choisie.To this end, the invention relates to a chronograph watch comprising a chronograph movement with a time base of frequency F, control means for starting, stopping and resetting the timing, a dial with analog display by means of a seconds hand in the center, and optionally a split-seconds hand, driven by the chronograph wheel which also drives, via gear trains, the hands of other counters and a hand of a counter with graduation in fractions of seconds. The chronograph watch is characterized in that the fractional seconds hand remains stationary for the duration of the timing and that it is rotated, when the timing is stopped, temporarily or permanently, by a pivoted feeler arm on a plate or bridge of the movement, the tilting of which is triggered by the chronograph stop means and the amplitude of the movement of which is controlled by the arrival of its spout abutting on a circular cam. The circular cam is driven by the chronograph wheel and has x elementary cams with angular aperture α each corresponding to a whole number of divisor seconds of 60. All the elementary cams have the same contour which determines the amplitude of the movement of the feeler arm and therefore the displacement of the hand of the second fraction counter in front of a determined graduation, the fractionation of the second being a function of the frequency F chosen.

Ainsi, pendant toute la durée du chronométrage, le compteur des fractions de seconde est désolidarisé de la chaíne cinématique, et l'énergie supplémentaire pour l'affichage de fractions de seconde est apportée par le ré-armage d'un ressort lorsqu'on effectue la remise à zéro du compteur. Thus, throughout the timing, the counter of the fractions of second is disconnected from the kinematic chain, and the additional energy for the display of fractions of a second is provided by the rearming of a spring when the counter is reset.

Comme on le verra dans la description détaillée, chaque came élémentaire peut être formée par un plan incliné ou par une succession d'étages correspondant chacun à une fraction de seconde.As will be seen in the detailed description, each elementary cam can be formed by an inclined plane or by a succession of corresponding stages each in a fraction of a second.

La came circulaire peut être entraínée directement par la roue de chronographe en étant concentrique de ladite roue et comporte alors 60 cames élémentaires d'ouverture angulaire α = 6°. De façon à augmenter le secteur balayé par l'aiguille de fractions de seconde, la came circulaire peut également être entraínée indirectement par l'intermédiaire d'un pignon en prise avec la roue de chronographe dans un rapport multiplicatif k tel que k • x = 60.The circular cam can be driven directly by the chronograph wheel while being concentric with said wheel and then comprises 60 elementary cams with angular opening α = 6 °. In order to increase the sector swept by the fractional seconds hand, the circular cam can also be driven indirectly by means of a pinion engaged with the chronograph wheel in a multiplicative ratio k such that k • x = 60.

L'aiguille de fractions de seconde peut être entraínée directement par le bras palpeur ou par un bras secondaire solidaire de celui-ci. Elle peut également être entraínée indirectement par l'intermédiaire d'une crémaillère solidaire dudit bras palpeur et dont le secteur denté engrène avec un pignon entraínant lui-même l'aiguille de fractions de seconde.The fractional second hand can be driven directly by the arm feeler or by a secondary arm secured thereto. It can also be driven indirectly by means of a rack integral with said arm feeler and whose toothed sector meshes with a pinion driving the needle itself fractions of a second.

On observera également que, pour permettre la libre rotation de la came pendant le chronométrage, le palpeur doit se situer en dehors de l'enveloppe de rotation de la came, ce qui entraíne l'aiguille de fractions de seconde à se positionner sur une position neutre "N" précédant la position 0 du compteur. Toutefois, en réduisant au minimum la distance entre le palpeur et l'enveloppe, les positions "N" et "0" peuvent être visuellement confondues, ce qui est en particulier avantageux pour un compteur à cadran circulaire.It will also be observed that, to allow free rotation of the cam during the timing, the probe must be outside the envelope of rotation of the cam, which causes the fractional seconds hand to position in a neutral position "N" preceding the 0 position of the counter. However, in minimizing the distance between the probe and the enclosure, the "N" and "0" can be visually confused, which is particularly advantageous for a counter with circular dial.

Le mécanisme et les moyens de commande du chronométrage (mise en route, arrêt et remise à zéro) peuvent être ceux connus de l'art antérieur, telle qu'une roue à colonnes agissant sur un levier solidaire du bras palpeur.The timing control mechanism and means (start-up, stop and reset) can be those known from the prior art, such as a wheel with columns acting on a lever secured to the feeler arm.

Selon le mode de réalisation représenté à la figure 1, une montre-chronographe selon l'invention comprend un cadran 2 indiquant l'heure courante au moyen d'une aiguille des heures 3, d'une aiguille des minutes 4, et d'une petite aiguille de secondes 5 décentrée sur un cadran 15 situé à 6h. Pour la fonction de chronométrage, la montre comprend également une aiguille de secondes au centre 6a, un compteur 17 indiquant les fractions de seconde au moyen d'une aiguille 7 et un compteur 18 indiquant les minutes au moyen d'une aiguille 8. La montre-chronographe comporte sur sa carrure 9 une couronne 12, un poussoir 11 pour le démarrage et l'arrêt et un poussoir 13 pour la remise à zéro. De façon connue, les poussoirs 11 et 13 pourraient être remplacés par un unique poussoir triple action. On a également représenté une aiguille de rattrapante 6b dont l'arrêt, respectivement la marche, est commandé par le poussoir de rattrapante 16 et sur le compteur 17 une aiguille supplémentaire de fractions de seconde lorsque la montre-chronographe est pourvue d'une rattrapante. La montre-chronographe comporte évidemment un mouvement de chronographe de fréquence F, non représenté comme étant bien connu de l'homme de métier.According to the embodiment shown in Figure 1, a chronograph watch according to the invention comprises a dial 2 indicating the current time at using an hour hand 3, a minute hand 4, and a small hand of seconds 5 off-center on a dial 15 located at 6 o'clock. For the function of timing, the watch also includes a central seconds hand 6a, a counter 17 indicating the fractions of a second by means of a hand 7 and a counter 18 indicating the minutes by means of a hand 8. The chronograph watch has on its middle 9 a crown 12, a pusher 11 for the start and stop and a push button 13 for reset. As is known, pushers 11 and 13 could be replaced by a single triple action pushbutton. We also represented a split-needle 6b whose stop, respectively the on, is controlled by the split-seconds pusher 16 and on the counter 17 a additional fractions of a second hand when the chronograph watch is with a split-second. The chronograph watch obviously has a frequency F chronograph movement, not shown to be well known to the skilled person.

En se référant maintenant aux figures 2, 3A et 3B, on décrit ci-après un premier mode de réalisation d'un mécanisme lorsque la montre-chronographe ne comporte pas de rattrapante et ne comporte donc pas le poussoir 16 représenté à la figure 1. A la figure 2 correspondant à une position de départ, on a seulement représenté les parties utiles à la compréhension de l'invention. Les positions d'arrêt et de remise à zéro seront expliquées plus loin en référence aux figures 4, 5 et 6 correspondant à un deuxième mode de réalisation.Referring now to Figures 2, 3A and 3B, below is described a first embodiment of a mechanism when the chronograph watch does not has no split-second and therefore does not include the pusher 16 shown in the figure 1. In figure 2 corresponding to a starting position, we only have represented the parts useful for understanding the invention. Stop positions and reset will be explained later with reference to Figures 4, 5 and 6 corresponding to a second embodiment.

L'élément moteur est constitué par la roue de chronographe 10 qui supporte et entraíne une came circulaire 20 en forme d'anneau, ladite came 20 étant formée par un enchaínement de x cames élémentaires 22, ayant une ouverture angulaire α correspondant à une seconde, soit de 6°. Ces cames élémentaires 22 sont destinées à coopérer avec un bras palpeur 27. La came circulaire 20 peut être une pièce fabriquée séparément puis fixée concentriquement sur la roue de chronographe 10. Elle peut également venir de matière avec la roue de chronographe 10.The driving element is constituted by the chronograph wheel 10 which supports and drives a circular cam 20 in the form of a ring, said cam 20 being formed by a sequence of x elementary cams 22, having an angular opening α corresponding to one second, or 6 °. These elementary cams 22 are intended to cooperate with a feeler arm 27. The circular cam 20 can be a part produced separately and then fixed concentrically on the chronograph wheel 10. It can also come in one piece with the chronograph wheel 10.

Comme on le voit sur la figure 3A, une came élémentaire 22 est formée par une succession d'étages 23i correspondant chacun à une fraction de seconde. Dans l'exemple représenté à la figure 3A, on peut compter 5 étages correspondant respectivement à 0, 1/5, 2/5, 3/5 et 4/5 de seconde à ajouter au temps chronométré. A cet effet, on choisit par exemple une fréquence correspondant à 18'000 alternances par heure, soit 5 coups par seconde.As seen in FIG. 3A, an elementary cam 22 is formed by a succession of stages 23i each corresponding to a fraction of a second. In the example represented in figure 3A, one can count 5 stages corresponding respectively at 0, 1/5, 2/5, 3/5 and 4/5 of a second to be added to the timed time. For this purpose, we choose for example a frequency corresponding to 18,000 vibrations per hour, or 5 strokes per second.

Dans la variante représentée à la figure 3B, une came élémentaire 22 comprend simplement un plan incliné 25, et la came circulaire 20 est formée par un disque plein.In the variant shown in FIG. 3B, an elementary cam 22 simply comprises an inclined plane 25, and the circular cam 20 is formed by a full disc.

La came circulaire 20, respectivement chaque came élémentaire 22, est destiné à recevoir, lorsqu'on arrête le chronométrage, le bras palpeur 27 pivoté sur un axe 28, et dont le bec 29 tombe en butée sur un étage 23i ou sur le plan incliné 25 en entraínant en rotation l'aiguille de fractions de seconde 7 qui lui est solidaire pour la positionner en regard d'une graduation 0, 1, 2, 3 ou 4 du compteur 17. Le compteur 17 comporte, avant la graduation O, une graduation "N" correspondant à une position neutre dans laquelle le bec 29 du bras palpeur 27 est totalement dégagé de la came 20 en permettant la libre rotation de la roue de chronographe 10. En réduisant au minimum la distance entre l'extrémité du bec 29 et le bord le plus externe de la came 20, on peut avoir les graduations O et N pratiquement confondues.The circular cam 20, respectively each elementary cam 22, is intended to receive, when the timing is stopped, the feeler arm 27 pivoted on a axis 28, and whose beak 29 abuts on a stage 23i or on the inclined plane 25 in driving in rotation the second fraction needle 7 which is integral with it for the position next to a graduation 0, 1, 2, 3 or 4 of the counter 17. The counter 17 comprises, before the graduation O, a graduation "N" corresponding to a position neutral in which the spout 29 of the feeler arm 27 is completely disengaged from the cam 20 by allowing the free rotation of the chronograph wheel 10. By reducing to minimum distance between the end of the spout 29 and the outermost edge of the cam 20, it is possible to have the graduations O and N practically combined.

Comme représenté à la figure 1, il est également possible de masquer la graduation N au moyen d'une découpe appropriée dans le cadran 2.As shown in Figure 1, it is also possible to hide the graduation N by means of an appropriate cut-out in the dial 2.

Le bras palpeur 27 est maintenu écarté de la came 20 par un bras de commande 31 dont l'extrémité comporte un plan d'impulsion 32 maintenu par un ressort (non représenté) en appui sur une colonne 33i d'une roue à colonnes 30 comportant des dents d'entraínement 34i. Le bras palpeur 27 est en outre pourvu d'un bras secondaire 35 comportant à son extrémité une goupille 36 destinée à coopérer avec une bascule 40 pivotée sur un axe 41, ladite bascule 40 étant maintenue dans la position représentée par une goupille de retenue 42 et permettant d'effectuer la remise à zéro du compteur 17 au moyen d'un doigt de commande 43, comme cela sera expliqué en référence aux figures 4 à 6.The feeler arm 27 is kept spaced from the cam 20 by an control 31, the end of which comprises a pulse plane 32 maintained by a spring (not shown) bearing on a column 33i of a column wheel 30 having drive teeth 34i. The feeler arm 27 is further provided with a secondary arm 35 comprising at its end a pin 36 intended to cooperate with a rocker 40 pivoted on an axis 41, said rocker 40 being held in the position represented by a retaining pin 42 and enabling the reset counter 17 by means of a control finger 43, like this will be explained with reference to Figures 4 to 6.

La bascule 40 comporte également deux bras 44, 46 comportant à leurs extrémités deux marteaux 45, 47 de remise à zéro des coeurs (non représentés) des autres compteurs.The lever 40 also comprises two arms 44, 46 comprising at their ends two hammers 45, 47 for resetting the hearts (not shown) of the other counters.

En se référant maintenant aux figures 4, 5 et 6 on décrit ci-après un deuxième mode de réalisation dans lequel les parties identiques ou analogues sont désignées par les mêmes références.Referring now to FIGS. 4, 5 and 6, a second description is given below. embodiment in which identical or analogous parts are designated by the same references.

La figure 4, qui correspond à la figure 2 dans la position de mise en marche, fait apparaítre deux différences essentielles au niveau des entraínements indirects de la came et de l'aiguille de fractions de seconde.FIG. 4, which corresponds to FIG. 2 in the start-up position, reveals two essential differences in terms of the indirect drives of the cam and needle for fractions of a second.

On voit tout d'abord que la came circulaire 19, formée par l'enchaínement de x cames élémentaires correspondant chacune à une seconde, n'est plus supportée directement par la roue de chronographe 10, mais par un pignon d'entraínement 21 de n2 dents en prise avec la denture 14 de la roue de chronographe comportant n1 dents, c'est-à-dire dans un rapport multiplicatif d'engrenages k = n1 / n2. Ce rapport k doit être un nombre entier diviseur de 60, de façon à ce qu'un tour complet du pignon d'entraínement 21 corresponde à un nombre entier x de secondes, c'est-à-dire en fait au nombre x de cames élémentaires 22. En d'autres termes le nombre x de cames élémentaires, multiplié par le rapport d'engrenage k, doit représenter 60 secondes ce qui correspond à la relation k x = 60.We see first of all that the circular cam 19, formed by the chain of x elementary cams each corresponding to one second, is no longer supported directly by the chronograph wheel 10, but by a drive pinion 21 of n 2 teeth in engagement with the teeth 14 of the chronograph wheel comprising n 1 teeth, that is to say in a multiplicative gear ratio k = n 1 / n 2 . This ratio k must be a divisor whole number of 60, so that a full revolution of the drive pinion 21 corresponds to an integer x of seconds, that is to say in fact to the number x of cams elementary 22. In other words the number x of elementary cams, multiplied by the gear ratio k, must represent 60 seconds which corresponds to the relation kx = 60.

Dans l'exemple représenté, on voit que la came 19 comporte 6 cames élémentaires 22, ce qui correspond à un rapport d'engrenage k = 10, ce qui permet par exemple d'avoir une roue de chronographe 10 avec n1 = 160 dents et un pignon d'entraínement 19 avec n2 = 16 dents. D'autres choix sont évidemment possible. Il serait en particulier avantageux d'avoir une roue de chronographe n1 = 180 dents de façon à pouvoir construire un mécanisme ayant de 2 à 6 cames élémentaires, simplement en choisissant des pignons d'entraínement 19 ayant respectivement 6, 9, 12, 15 ou 18 dents.In the example shown, it can be seen that the cam 19 has 6 elementary cams 22, which corresponds to a gear ratio k = 10, which makes it possible for example to have a chronograph wheel 10 with n 1 = 160 teeth and a drive pinion 19 with n 2 = 16 teeth. Other choices are obviously possible. It would be particularly advantageous to have a chronograph wheel n 1 = 180 teeth so as to be able to build a mechanism having 2 to 6 elementary cams, simply by choosing drive pinions 19 having 6, 9, 12, 15 respectively or 18 teeth.

Ce mode de réalisation présente également l'avantage de procurer des cames élémentaires ayant une ouverture angulaire α importante (60° dans l'exemple représenté) permettant de disposer plus facilement les étages 23i ou le plan incliné 25. Il permet également d'avoir des étages 23i (respectivement un plan incliné 25) plus profond en procurant un plus grand débattement au bras palpeur 27 et corrélativement à l'aiguille de fractions de seconde 7, dans le cas où elle serait, comme dans le premier mode de réalisation, solidaire du bras palpeur 27. Les graduations du compteur 17 peuvent alors être davantage espacées, ce qui en facilite la lecture. Dans l'exemple représenté, on voit que les graduations vont de 0 à 5, ce qui correspond à un fractionnement en 1/6 de seconde. A cet effet, chaque came élémentaire 22 comporte 6 étages 23i et on choisit une fréquence de 21600 alternances par heure.This embodiment also has the advantage of providing cams elementary with a large angular opening α (60 ° in the example shown) making it easier to arrange the floors 23i or the inclined plane 25. It also makes it possible to have stages 23i (respectively an inclined plane 25) deeper by providing greater travel to the feeler arm 27 and correlatively to the fractions 7 second needle, in case it is, as in the first embodiment, integral with the feeler arm 27. The graduations of counter 17 can then be further spaced, which facilitates reading. In the example shown, we see that the graduations go from 0 to 5, which which corresponds to a fractionation in 1/6 of a second. For this purpose, each cam elementary 22 has 6 stages 23i and a frequency of 21,600 is chosen alternations per hour.

Ce deuxième mode de réalisation diffère également de celui décrit en premier en ce que l'aiguille de fractions de seconde 7 n'est plus entraínée directement par le bras palpeur 27, mais indirectement par une crémaillère 37, solidaire dudit bras palpeur 27, et dont le secteur denté 38 engrène avec un pignon 39 supportant l'aiguille de fractions de seconde 7 et l'entraínant en rotation. L'adjonction de la crémaillère 37 présente l'avantage de pouvoir encore amplifier le débattement de l'aiguille de fractions de secondes 7 et de donner plus de liberté dans le positionnement du compteur 17 sur le cadran 2.This second embodiment also differs from that described first. in that the second fraction needle 7 is no longer directly driven by the feeler arm 27, but indirectly by a rack 37, integral with said arm probe 27, and of which the toothed sector 38 meshes with a pinion 39 supporting the second fractions needle 7 and driving it in rotation. The addition of rack 37 has the advantage of being able to further amplify the travel of the fractions needle of 7 seconds and give more freedom in the positioning of the counter 17 on the dial 2.

A la figure 5 on a maintenant représenté la position du mécanisme lorsqu'on arrête le chronométrage. La roue à colonnes 30 pivote et, sous l'action du ressort 32, le bec 31a du bras de commande 31 tombe entre les deux colonnes 33i et 33i+1 en libérant le bras palpeur 27 dont le basculement sera limité par l'arrivée de son bec 29 en butée sur un étage 23i d'une came élémentaire 22 de la came 20. Ce mouvement de basculement entraíne également la crémaillère 37 dont le secteur denté 38 va faire tourner le pignon 39 commandant le déplacement de l'aiguille 7 sur le cadran 17 en regard d'une graduation correspondant à l'étage 55i sur lequel le palpeur 37 est venu en butée.In Figure 5 we have now shown the position of the mechanism when the timing is stopped. The column wheel 30 pivots and, under the action of the spring 32, the spout 31a of the control arm 31 falls between the two columns 33 i and 33 i + 1 by releasing the feeler arm 27 whose tilting will be limited by the arrival of its beak 29 in abutment on a stage 23i of an elementary cam 22 of the cam 20. This tilting movement also causes the rack 37 whose toothed sector 38 will rotate the pinion 39 controlling the movement of the needle 7 on the dial 17 opposite a graduation corresponding to the stage 55 i on which the probe 37 has come into abutment.

La figure 6 représente la position du mécanisme lorsqu'on effectue la remise à zéro, c'est-à-dire en fait lorsqu'on ramène les aiguilles 6 et 8 à zéro au moyen des marteaux 23 et 25 agissant sur des coeurs (non représentés) et l'aiguille de fractions de seconde 7 en position neutre N. Cette manoeuvre est effectuée en appuyant sur le poussoir 13 pour faire pivoter la bascule 40 et exercer, par l'intermédiaire du doigt 43, une pression sur la goupille 36 du bras 35 pour faire basculer la crémaillère 37 et le maintenir, sans intervention de la roue à colonnes 30, en position de repos dans laquelle le bec 29 du bras palpeur 27 permet à nouveau une libre rotation de la came 19. L'aiguille 7 est ramenée en position neutre N par l'entraínement en rotation du pignon 39 par le secteur denté 38 de la crémaillère 37.Figure 6 shows the position of the mechanism when performing the reset. zero, i.e. in fact when needles 6 and 8 are brought back to zero using the hammers 23 and 25 acting on hearts (not shown) and the fractions needle second 7 in neutral position N. This operation is carried out by pressing the push-button 13 to pivot the rocker 40 and exercise, by means of finger 43, pressure on the pin 36 of the arm 35 to tilt the rack 37 and the maintain, without intervention of the column wheel 30, in the rest position in which the spout 29 of the feeler arm 27 again allows free rotation of the cam 19. The needle 7 is returned to the neutral position N by the rotational drive of the pinion 39 by the toothed sector 38 of the rack 37.

Lorsqu'on veut effectuer un nouveau chronométrage, la roue à colonnes 30 avance d'un pas, ce qui provoque à la fois la libération de la goupille 36, et le blocage de l'extrémité 31a du bras 31 sur une colonne 33i de la roue à colonne 30, comme représenté sur la figure 4. When you want to perform a new timing, the column wheel 30 advances by one step, which causes both the release of the pin 36, and the blocking from the end 31a of the arm 31 on a column 33i of the column wheel 30, as shown in figure 4.

La figure 7 représente un deuxième mode de réalisation qui illustre des variantes possibles du mécanisme d'affichage de fractions de seconde selon l'invention.FIG. 7 represents a second embodiment which illustrates possible variants of the fraction display mechanism according to the invention.

Dans le mode de réalisation représenté, on voit que la came 19 comporte 4 cames élémentaires 22 (x = 4), ce qui correspond à un rapport d'engrenage k = 15, et permet par exemple d'avoir une roue de chronographe 10 à 180 dents (n1 = 180) et un pignon d'entraínement 21 à 12 dents (n2 = 12). Comme on le voit, en diminuant le nombre de cames élémentaires 22, on augmente la possibilité de fractionner une seconde. Dans l'exemple représenté à la figure 7, on voit que chaque came élémentaire comporte 10 étages 23i, ce qui correspond à un fractionnement en dixième de seconde, à condition bien sûr d'utiliser une fréquence de 36000 alternances par heure. Avec cette même fréquence on pourrait également concevoir une came élémentaire ne comportant que 5 étages pour un chronométrage à 1/5 seconde et permettant de corriger le défaut d'enclenchement au départ.In the embodiment shown, it can be seen that the cam 19 has 4 elementary cams 22 (x = 4), which corresponds to a gear ratio k = 15, and allows for example to have a chronograph wheel 10 to 180 teeth (n 1 = 180) and a drive pinion 21 to 12 teeth (n 2 = 12). As can be seen, by reducing the number of elementary cams 22, the possibility of splitting a second is increased. In the example shown in Figure 7, we see that each elementary cam has 10 stages 23 i , which corresponds to a fractionation in tenths of a second, provided of course using a frequency of 36,000 vibrations per hour. With this same frequency, it is also possible to design an elementary cam comprising only 5 stages for timing at 1/5 second and making it possible to correct the engagement fault at the start.

Le même résultat pourrait être obtenu avec une fréquence de 28800 alternances par heure pour un chronométrage à 1/4 de secondes.The same result could be obtained with a frequency of 28800 alternations per hour for timing to 1/4 of a second.

Selon une autre variante représentée dans la figure 7, on voit que le pignon d'entraínement 39 est remplacé par un train multiplicatif d'engrenages 24, 26, de sorte que l'aiguille de fractions de seconde 7 entraínée par le pignon mené 26 peut balayer tout le tour d'un cadran circulaire du compteur 17. Cette construction présente également l'avantage d'inverser le sens de rotation de l'aiguille 7 et de procurer ainsi un affichage dans le sens horaire.According to another variant shown in FIG. 7, it can be seen that the pinion 39 is replaced by a multiplying gear train 24, 26, so that the second fraction needle 7 driven by the driven pinion 26 can sweep all around a circular dial of counter 17. This construction presents also the advantage of reversing the direction of rotation of the needle 7 and thus providing a clockwise display.

La figure 8représente un quatrième mode de réalisation dans lequel le dispositif selon l'invention est également appliqué au mécanisme de l'aiguille de rattrappante 6b en permettant ainsi de lire un temps intermédiaire chronométré avec la même précision de fractions de seconde qu'un temps final. Les parties similaires ou identiques sont désignées par les mêmes références que celles indiquées dans les modes de réalisation précédents.Figure 8 shows a fourth embodiment in which the device according to the invention is also applied to the mechanism of the needle split-second 6b, thus making it possible to read a timed intermediate time with the same precision of fractions of a second as a final time. Similar parties or identical are designated by the same references as those indicated in the previous embodiments.

Une came 20, comportant des cames élémentaires 22 est entraínée par une roue de chronographe 10, elle-même en prise avec celle qui entraíne l'aiguille de seconde au centre 6a, et pouvant être désolidarisée de celle-ci par des dispositifs connus dans une montre-chronographe à rattrapante. Le dispositif comprend également une roue à colonnes 30a pourvue de colonnes 33i et de dents 34i, comme décrit précédemment. La rotation de cette roue à colonnes 30a est commandée par un dispositif (non représenté) actionné par le bouton-poussoir 16.A cam 20, comprising elementary cams 22 is driven by a chronograph wheel 10, itself engaged with that which drives the second in the center 6a, and being able to be separated from the latter by devices known in a split-seconds chronograph watch. The device includes also a column wheel 30a provided with columns 33i and teeth 34i, as described previously. The rotation of this column wheel 30a is controlled by a device (not shown) actuated by the push button 16.

Le dispositif comprend également un bras palpeur 27 prolongé par un bras de commande 31, pivoté sur un axe 28, ledit bras palpeur 27 comportant un bec 29 dont l'extrémité vient tomber dans une came élémentaire 22, lorsque l'actionnement du poussoir 16 fait tomber un ergot 32 du bras de commande 31 entre deux colonnes 33i de la roue à colonne 30 sous l'action d'un ressort (non représenté). Le bras de commande 31 comporte également, comme dans le deuxième mode de réalisation, une crémaillère 37 dont le secteur denté 38 engrène avec un pignon 39 entraínant l'aiguille de fractions de seconde 7b de la rattrapante 6b en face d'une graduation du compteur de fractions de seconde 17.The device also comprises a feeler arm 27 extended by an arm for control 31, pivoted on an axis 28, said feeler arm 27 comprising a spout 29 of which the end comes to fall into an elementary cam 22, when the actuation of the pusher 16 drops a lug 32 of the control arm 31 between two columns 33i of the column wheel 30 under the action of a spring (not shown). The arm of command 31 also includes, as in the second embodiment, a rack 37 whose toothed sector 38 meshes with a pinion 39 driving the split seconds hand 7b of the split-second 6b opposite a graduation of the fractional seconds counter 17.

Le dispositif diffère de ceux précédemment décrits essentiellement en ce l'arrêt de la roue de chronographe 10 entraínant la came 20 est provoqué par la pince de rattrapante 50. Dans l'exemple représenté, la pince 50 est constituée par deux bras coudés 51a, 51b pivotés au niveau de leurs coudes respectivement sur des plots 52a, 52b et représentés à la figure 8 dans la position où leurs extrémités sont en appui sur la denture 14 de la roue de chronographe 10 sous l'action d'un ressort (non représenté).The device differs from those previously described essentially in that the stop of the chronograph wheel 10 driving the cam 20 is caused by the clamp split-second 50. In the example shown, the clamp 50 is formed by two bent arms 51a, 51b pivoted at their elbows respectively on pads 52a, 52b and shown in Figure 8 in the position where their ends are in support on the teeth 14 of the chronograph wheel 10 under the action of a spring (not represented).

L'un des bras 51 a est un bras de commande pourvu, à son extrémité n'agissant pas sur la denture 14, d'une vis 54 dont la tête agit sur l'extrémité correspondante de l'autre bras 51b, pour le faire basculer en même temps que le bras de commande 51a. De façon avantageuse la vis 54 est une vis à excentrique permettant de régler la pression exercée par la pince sur la denture 14.One of the arms 51 a is a control arm provided, at its end not acting on the toothing 14, of a screw 54 whose head acts on the corresponding end of the other arm 51b, to cause it to tilt at the same time as the arm 51a. Advantageously, the screw 54 is an eccentric screw to adjust the pressure exerted by the clamp on the teeth 14.

Cette manoeuvre, ouvert/fermé, de la pince 50 est commandée par la roue à colonnes 30 dont les colonnes 33i coopèrent avec un bec 55 terminé par un méplat 56 du bras de commande 51a de la pince 50 pour l'ouvrir. Inversement les espaces entre les colonnes 33i permettent au bec 55 de retomber entre deux colonnes et d'assurer la fermeture de la pince 50.This operation, open / closed, of the clamp 50 is controlled by the wheel columns 30 whose columns 33i cooperate with a spout 55 ending in a flat 56 of the control arm 51a of the clamp 50 to open it. Conversely, spaces between the columns 33i allow the spout 55 to fall between two columns and closing the clamp 50.

L'aiguille de fractions de seconde 7b pour le chronométrage d'un temps intermédiaire au moyen de la rattrapante 6b et l'aiguille de fractions de seconde 7a pour le chronométrage d'un temps final au moyen de l'aiguille de secondes au centre 6a peuvent être sur un même compteur 17, comme représenté à la figure 1 étant donné que ces aiguilles sont entraínées par des mécanismes reposant sur le même principe, mais séparés. Il est également possible de concevoir cet affichage de fractions de seconde sur deux compteurs séparés, le compteur lié à la rattrapante 6b étant par exemple positionné prés du poussoir de rattrapante 16 et le compteur de minutes 18 étant alors déplacé à un autre endroit du cadran.The fractions second hand 7b for timing a time intermediate by means of the split-second 6b and the second fraction needle 7a for timing a final time using the second hand in the center 6a can be on the same counter 17, as shown in FIG. 1 being given that these needles are driven by mechanisms based on the same principle, but separate. It is also possible to design this display of fractions of a second on two separate counters, the counter linked to the split-second 6b being, for example, positioned near the split-seconds pusher and the counter 18 minutes then being moved to another location on the dial.

Les figures 9 et 10 représentent une variante du dispositif de fractions de seconde pour rattrapante précédemment décrit en référence à la figure 8. Il diffère en ce que l'affichage de fractions de seconde s'effectue sur un compteur 17b à cadran circulaire pour lequel la liaison cinématique (non représentée) peut être du type de l'une quelconque des liaisons précédemment décrites. Il diffère également en ce que chaque came élémentaire 22 correspond à 2 secondes, c'est-à-dire à un pas angulaire α = 12°, et comporte un nombre double d'étage 23i. Ainsi lorsque le bec 29 du bras palpeur tombe par exemple sur le 2ème étage en arrêtant la rattrapante, l'aiguille 7b vient se positionner en face de l'indication 20 du compteur 17a. Si le bec 29 tombe sur le 8ème étage, l'aiguille 7b fait un tour complet et vient ensuite se positionner en face de l'indicateur 30 du compteur 17a. Cette construction a l'avantage de faciliter l'usinage des étages 23i des cames élémentaires 22 étant donné que l'angle α est plus grand. Il est bien évident que d'autres choix sont possibles à condition le nombre de secondes correspondant à une came élémentaire soit un diviseur entier de 60. Cette variante vient d'être décrite en référence à la rattrapante pour le chronométrage d'un temps intermédiaire mais peut évidemment être appliquée au chronométrage d'un temps final.FIGS. 9 and 10 show a variant of the device for fractions of second for split-second previously described with reference to Figure 8. It differs in that fractions of a second are displayed on a dial counter 17b circular for which the kinematic connection (not shown) can be of the type any of the previously described links. It also differs in that each elementary cam 22 corresponds to 2 seconds, that is to say to a step angular α = 12 °, and has a double number of stages 23i. So when the beak 29 of the feeler arm, for example, falls on the 2nd floor, stopping the split-second, the needle 7b is positioned opposite the indication 20 of the counter 17a. If the beak 29 falls on the 8th stage, the needle 7b makes a complete turn and then comes position in front of the indicator 30 of the counter 17a. This construction has the advantage of facilitating the machining of the stages 23i of the elementary cams 22 being given that the angle α is larger. It is obvious that other choices are possible provided the number of seconds corresponding to an elementary cam or an integer divisor of 60. This variant has just been described with reference to the split-second for the timing of an intermediate time but can obviously be applied to the timing of a final time.

Il est bien évident que l'homme de métier peut apporter d'autres modifications au mécanisme qui vient d'être décrit sans sortir du cadre de l'invention, par exemple en combinant entre elles les variantes qui ont été mentionnées.It is obvious that the skilled person can make other modifications. to the mechanism which has just been described without departing from the scope of the invention, for example by combining together the variants which have been mentioned.
