Definitions
- the present invention relates to a device for simultaneous resetting of two time counters, including chronograph, whose pivot axes are integral with respective resetting cams in the form of cores, comprising a reset lever comprising two hammers, means for selectively exerting on this lever a torque for applying the two hammers against the reset cams and means of articulation of these hammers relative to the reset lever.
- a heart-shaped reset cam is associated with the axis of the counter and a hammer whose orientation of the striking face bears against symmetrical shoulders of the heart, serves to define the angular position corresponding to the zero of the counter.
- this cam is moved away from its angular position corresponding to the counter zero, and the hammer strikes laterally against it, the force of the hammer is transformed into a torque that rotates the cam until the striking face of the hammer press on the two shoulders of the heart-shaped cam and immobilize it.
- one of the two hammers be adjustable or resilient to absorb tolerances. Which says adjustment of a moving part says means to fix its position Given the dimensions of the pieces, when it is about a wrist chronograph, there is a good chance that the adjustment carried out goes wrong when one wants to fix the set position. If it is a moving part connected by friction, the setting may be out of adjustment.
- a chronograph mechanism has a large number of parts and for reasons of space, it is not always possible to have this pivot axis of the hammers on the carrier lever and the axis of rotation of the lever in the above positions.
- the object of the present invention is to overcome, at least in part, the disadvantages of the aforementioned solutions.
- this invention relates to a device for simultaneous resetting of two time counters according to claim 1.
- the chronograph mechanism illustrated in part is that of a conventional mechanism making use of a central command called column wheel 1. It is specified however that the invention relates essentially to a new design of the reset lever to hammers 2 and that such a lever could quite well be used with the same advantages in any mechanism in which two time counters (minutes and seconds for example) must be reset simultaneously using a same reset lever.
- the column wheel 1 is secured to a ratchet tooth 1a in engagement with a positioning pawl 3 and with a drive pawl 4a hinged to the end of a control lever 4, itself articulated about an axis 4b.
- This rocker is used to advance the column wheel 1 step, including moving the bodies of the reset mechanism of the position shown in Figure 1 to that shown in Figure 2 and vice versa.
- the part of this mechanism to which the present invention relates relates to the reset lever with two hammers 2.
- This is shown separately in Figure 3 with a spring 5 which applies a force F on an ankle 2a secured to the lever resetting 2, developing a torque about the pivot axis 2b of this reset lever 2.
- This reset lever 2 is shaped to provide a finger 2c in engagement with the columns 1b of the wheel to columns 1, under the pressure of the spring 5.
- a column 1b which respectively controls the reset position shown in Figures 1 and 3 and the running position of the counters, as will be explained below.
- the two hammer reset lever 2 further comprises two pins 2d, 2e which are respectively engaged in two openings 6a, 6b of a piece 6 with two hammers 6c, 6d an elongated opening 6a and an opening 6b sized to allow the elongate opening 6a, so to the piece 6, to rotate a limited angle around the pin 2d.
- the hammers 6c, 6d are engaged with two heart-shaped cams 7, 8 respectively which are each integral with the pivot axis 7a, respectively 8a of the movable indicator member (not shown) of one of the two counters for example, minutes and seconds.
- FIG. 3 shows the effect obtained thanks to the existence of the elongate opening 6a forming a limited slide, according to the solution proposed by the present invention. It can be seen that this slide is oriented so that, during the reset, the direction of perpendicular lowered from the axis of the pin 2d on this slide 6a and which corresponds to the direction of the force F1 transmitted from the lever of resetting 2 to the double hammer part 6, cuts the line joining the axes of the reset cams 7a, 8a at a point capable of improving the distribution of the forces F2, F3 exerted on the cams 7, 8 respectively. With reference to FIG. 4, it can be seen that the slide 6a makes it possible to reduce this force F1 more towards the cam 8.
- this has the effect of practically doubling the force F3 transmitted to this cam 8 with respect to that which is transmitted in the case of Figure 4, without decreasing the F2 exerted on the cam 7 and this independently of the position of the pivot axis of the lever 2b and the pin 2d.
- the opening 6b it is chosen to provide a degree of freedom sufficient to allow the piece 6 to rotate a limited degree around the ankle 2d to ensure a contact between the hammers 6c and 6d with hearts 7 and 8 respectively, which allows the rotation of these two hearts. Indeed, if the hammers were not limited in their movement around the ankle 2d, they could take a position such that at the time of the contact between the hammers 6c and 6d with the hearts, it is not the working surface of the hammers which acts on the hearts, which would cause a blockage of the rotation of the hearts.
- the axis of rotation of the lever should be located, relative to the straight line connecting the axes of the reset cams, in a position that allows to apply to the pivot axis of the hammers a force whose direction form, with the straight line connecting the axes of the reset cams, an angle as close as possible to the right angle, so that the torque transmitted to each cam is sufficient to rotate them.

Abstract
Description
La présente invention se rapporte à un dispositif de remise à zéro simultané de deux compteurs de temps, notamment de chronographe, dont les axes de pivotement sont solidaires de cames de remise à zéro respectives en formes de coeurs, comprenant un levier de remise à zéro comportant deux marteaux, des moyens pour exercer sélectivement sur ce levier un couple pour appliquer les deux marteaux contre les cames de remise à zéro et des moyens d'articulation de ces marteaux par rapport au levier de remise à zéro.The present invention relates to a device for simultaneous resetting of two time counters, including chronograph, whose pivot axes are integral with respective resetting cams in the form of cores, comprising a reset lever comprising two hammers, means for selectively exerting on this lever a torque for applying the two hammers against the reset cams and means of articulation of these hammers relative to the reset lever.
Pour effectuer la remise à zéro d'un compteur, notamment de chronographe, on associe une came de remise à zéro en forme de coeur à l'axe du compteur et un marteau dont l'orientation de la face de frappe, en appui sur les épaulements symétriques du coeur, sert à définir la position angulaire correspondant au zéro du compteur. Dès que cette came est écartée de sa position angulaire correspondant au zéro du compteur, et que le marteau frappe latéralement contre elle, la force du marteau se transforme en un couple qui fait tourner la came jusqu'à ce que la face de frappe du marteau appuie sur les deux épaulements de la came en forme de coeur et l'immobilise. Si cette came a tourné de moins de 180°, le marteau la fait tourner d'un demi tour dans le sens contraire à son sens de rotation, si elle a tourné de plus de 180°, le marteau la ramène à zéro en la faisant tourner dans son sens de rotation, dans le cas d'un coeur symétrique.To reset a counter, especially a chronograph, a heart-shaped reset cam is associated with the axis of the counter and a hammer whose orientation of the striking face bears against symmetrical shoulders of the heart, serves to define the angular position corresponding to the zero of the counter. As soon as this cam is moved away from its angular position corresponding to the counter zero, and the hammer strikes laterally against it, the force of the hammer is transformed into a torque that rotates the cam until the striking face of the hammer press on the two shoulders of the heart-shaped cam and immobilize it. If this cam has rotated less than 180 °, the hammer rotates it half a turn in the opposite direction to its direction of rotation, if it has turned more than 180 °, the hammer brings it back to zero by making it turn in its direction of rotation, in the case of a symmetrical heart.
Pour effectuer la remise à zéro simultanée de deux compteurs, on utilise un levier à deux marteaux. Compte tenu des différentes tolérances, un tel dispositif ne permet en pratique pas d'obtenir un appui simultané des deux faces de frappe des marteaux sur les deux épaulements des deux coeurs en position de remise à zéro. On n'aura en effet un appui que sur trois des quatre épaulements, en sorte que la position zéro de l'un des deux marteaux n'est pas définie avec précision.To perform the simultaneous reset of two counters, a lever with two hammers is used. Given the different tolerances, such a device does not allow in practice to obtain a simultaneous support of the two striking faces of the hammers on the two shoulders of the two hearts in reset position. We will only have support on three of the four shoulders, so that the zero position of one of the two hammers is not precisely defined.
Il existe différentes solutions pour résoudre ce problème. On peut effectuer une retouche de la face de frappe du marteau qui appuie sur les deux épaulements jusqu'à ce que la face de frappe de l'autre appuie sur les deux épaulements. Il s'agit là d'un travail de mise au point délicat.There are different solutions to solve this problem. A touch-up of the striking face of the hammer that presses on the two shoulders can be performed until the striking face of the other presses on the two shoulders. This is a delicate work of fine tuning.
On a aussi proposé que l'un des deux marteaux soit réglable ou élastique pour absorber les tolérances. Qui dit réglage d'une pièce mobile dit moyens pour fixer sa position Compte tenu des dimensions des pièces, lorsqu'il s'agit d'un chronographe bracelet, il y a de grandes chances pour que le réglage effectué se dérègle lorsque l'on veut fixer la position réglée. Si il s'agit d'une pièce mobile reliée par friction, le réglage risque de se dérégler.It has also been proposed that one of the two hammers be adjustable or resilient to absorb tolerances. Which says adjustment of a moving part says means to fix its position Given the dimensions of the pieces, when it is about a wrist chronograph, there is a good chance that the adjustment carried out goes wrong when one wants to fix the set position. If it is a moving part connected by friction, the setting may be out of adjustment.
Enfin, on a proposé dans le CH 571'741 de relier les deux marteaux au levier porteur par un axe de pivotement. Dans ce cas, l'axe de pivotement des marteaux doit se situer le plus près possible du milieu de la droite qui relie les axes de pivotement des cames de remise à zéro. Par ailleurs, l'axe de rotation du levier doit se situer, par rapport à la droite reliant les axes des cames de remise à zéro, dans une position qui permette d'appliquer à l'axe de pivotement des marteaux une force dont la direction forme, avec la droite reliant les axes des cames de remise à zéro, un angle aussi proche que possible de l'angle droit, afin que le couple transmis à chaque came soit suffisant pour les faire tourner.Finally, it was proposed in CH 571'741 to connect the two hammers to the carrier lever by a pivot axis. In this case, the pivot axis of the hammers must be as close as possible to the middle of the line that connects the pivot axes of the reset cams. Moreover, the axis of rotation of the lever must be, relative to the straight line connecting the axes of the reset cams, in a position which makes it possible to apply to the pivot axis of the hammers a force whose direction form, with the straight line connecting the axes of the reset cams, an angle as close as possible to the right angle, so that the torque transmitted to each cam is sufficient to rotate them.
Or, un mécanisme de chronographe comporte un grand nombre de pièces et pour des questions d'encombrement, il n'est pas toujours possible de disposer cet axe de pivotement des marteaux sur le levier porteur ainsi que l'axe de rotation du levier dans les positions susmentionnées.However, a chronograph mechanism has a large number of parts and for reasons of space, it is not always possible to have this pivot axis of the hammers on the carrier lever and the axis of rotation of the lever in the above positions.
Le but de la présente invention est de remédier, au moins en partie, aux inconvénients des solutions susmentionnées.The object of the present invention is to overcome, at least in part, the disadvantages of the aforementioned solutions.
A cet effet, cette invention a pour objet un dispositif de remise à zéro simultané de deux compteurs de temps selon la revendication 1.For this purpose, this invention relates to a device for simultaneous resetting of two time counters according to
Les dessins annexés illustrent, schématiquement et à titre d'exemple, une forme d'exécution du dispositif objet de la présente invention.

- Fig. 1 is a plan view of the entire resetting mechanism of the chronograph counters in the reset position;
- FIG. 2 is a view similar to that of FIG. 1 in the deactivated position of the reset mechanism;
- Figure 3 is a partial view of Figure 1 showing only the lever and the two reset hammers with the forces applied to the cams;
- Figure 4 is a view similar to Figure 3 illustrating the forces applied to the cams, by transposing the solution according to the state of the art to the example according to the present invention.
Le mécanisme de chronographe illustré en partie est celui d'un mécanisme classique faisant usage d'une commande centrale dite à roue à colonnes 1. Il est précisé toutefois que l'invention se rapporte essentiellement à une nouvelle conception du levier de remise à zéro à marteaux 2 et qu'un tel levier pourrait tout à fait être utilisé avec les mêmes avantages dans n'importe quel mécanisme dans lequel deux compteurs de temps (minutes et secondes par exemple) doivent être remis à zéro simultanément à l'aide d'un même levier de remise à zéro.The chronograph mechanism illustrated in part is that of a conventional mechanism making use of a central command called
La roue à colonnes 1 est solidaire d'une denture à rochet 1a en prise avec un cliquet de positionnement 3 et avec un cliquet d'entraînement 4a articulé à l'extrémité d'une bascule de commande 4, elle-même articulée autour d'un axe 4b. Cette bascule sert à faire avancer la roue à colonnes 1 pas à pas, faisant notamment déplacer les organes du mécanisme de remise à zéro de la position illustrée par la figure 1 à celle illustrée par la figure 2 et vice versa.The
La partie de ce mécanisme sur laquelle porte la présente invention est relative au levier de remise à zéro à deux marteaux 2. Celui-ci est illustré séparément par la figure 3 avec un ressort 5 qui applique une force F sur une cheville 2a solidaire du levier de remise à zéro 2, développant un couple autour de l'axe de pivotement 2b de ce levier de remise à zéro 2. Ce levier de remise à zéro 2 est conformé pour ménager un doigt 2c en prise avec les colonnes 1b de la roue à colonnes 1, sous la pression du ressort 5. Comme on le voit sur les figures 1 et 2, un pas sur deux de la denture 1a de la roue à colonnes 1, le doigt 2c est entre deux colonnes 1b et un pas sur deux il appuie sur une colonne 1b, ce qui commande respectivement la position de remise à zéro illustrée par les figures 1 et 3 et la position de marche des compteurs, comme on va l'expliquer ci-après.The part of this mechanism to which the present invention relates relates to the reset lever with two
Le levier de remise à zéro à deux marteaux 2 comporte encore deux chevilles 2d, 2e qui sont engagées respectivement dans deux ouverture 6a, 6b d'une pièce 6 à deux marteaux 6c, 6d une ouverture allongée 6a et une ouverture 6b dimensionnées pour permettre à l'ouverture allongé 6a, donc à la pièce 6, de tourner d'un angle limité autour de la cheville 2d. Les marteaux 6c, 6d sont en prise avec deux cames en forme de coeur 7, respectivement 8 qui sont chacune solidaire de l'axe de pivotement 7a, respectivement 8a de l'organe indicateur mobile (non représenté) de l'un des deux compteurs, par exemple, minutes et secondes.The two
Si on avait un simple pivotement de la pièces 6 à double marteaux 6c, 6d, autour de la cheville 6a, comme dans l'état de la technique, tel qu'illustré par la figure 4, les forces transmises aux cames 7 et 8 seraient celles illustrées par cette figure 4, c'est-à-dire une force très faible sur la came 8, le pivotement autour de la cheville garantissant le contact des deux marteaux 6c, 6d contre les deux épaulements des deux coeurs 7 et 8.If there was a simple pivoting of the
La figure 3 montre l'effet obtenu grâce à l'existence de l'ouverture allongée 6a formant une coulisse limitée, selon la solution proposée par la présente invention. On peut constater que cette coulisse est orientée pour que, lors de la remise à zéro, la direction de la perpendiculaire abaissée de l'axe de la cheville 2d sur cette coulisse 6a et qui correspond à la direction de la force F1 transmise du levier de remise à zéro 2 à la pièce à double marteau 6, coupe la droite joignant les axes des cames de remise à zéro 7a, 8a en un point apte à améliorer la répartition des forces F2, F3 exercées sur les cames 7, respectivement 8. Par rapport à la figure 4, on peut constater que la coulisse 6a permet de ramener cette force F1 davantage en direction de la came 8. Comme on le constate, ceci a pour effet de pratiquement doubler la force F3 transmise à cette came 8 par rapport à celle qui est transmise dans le cas de la figure 4, sans diminuer celle F2 exercée sur la came 7 et ceci indépendamment de la position de l'axe de pivotement du levier 2b et de la cheville 2d.FIG. 3 shows the effect obtained thanks to the existence of the
Quant à l'ouverture 6b, elle est choisie pour offrir un degré de liberté suffisant pour permettre à la pièce 6 de pivoter d'un degré limité autour de la cheville 2d en vue d'assurer une prise de contact entre les marteaux 6c et 6d avec les coeurs 7 et 8 respectivement, qui permette la rotation de ces deux coeurs. En effet, si les marteaux n'étaient pas limités dans leur déplacement autour de la cheville 2d, ils pourraient prendre une position telle qu'au moment de la prise de contact entre les marteaux 6c et 6d avec les coeurs, ce ne soit pas la surface de travail des marteaux qui agisse sur les coeurs, ce qui provoquerait un blocage de la rotation des coeurs.As for the opening 6b, it is chosen to provide a degree of freedom sufficient to allow the
Toutefois, comme le montre l'exemple de la figure 4, le contact simultané des marteaux 6c, 6d et des épaulements des coeurs n'est pas garant d'une bonne transmission de force pour ramener les cames 7 et 8 à zéro. Les deux problèmes sont indépendants l'un de l'autre. L'avantage de la solution proposée réside dans le fait qu'elle permet à la fois de modifier l'orientation de la force F1 et d'améliorer de ce fait la répartition des forces F2, F3, tout en garantissant un contact simultané des marteaux 6c, 6d sur les épaulements des coeurs, ce que ne permettait pas de faire la solution susmentionnée de l'état de la technique avec un simple pivotement autour d'un axe, puisqu'elle nécessitait de disposer l'axe de pivotement lui-même sensiblement à mi-distance des axes de pivotement des deux coeurs. Par ailleurs, l'axe de rotation du levier devait se situer, par rapport à la droite reliant les axes des cames de remise à zéro, dans une position qui permette d'appliquer à l'axe de pivotement des marteaux une force dont la direction forme, avec la droite reliant les axes des cames de remise à zéro, un angle aussi proche que possible de l'angle droit, afin que le couple transmis à chaque came soit suffisant pour les faire tourner.However, as shown in the example of FIG. 4, the simultaneous contact of the
