Abstract

The watch comprises a conventional timepiece movement driving the hours-hands, the minutes-hands and the seconds-hands, to which is added a chronograph module the frame of which, having the shape of a bell, covers the movement of the timepiece. The chronograph is autonomous, i.e. its indicators are not driven by the basis movement but by electric motors situated around the central movement, fed by a battery and piloted by a quartz oscillator, the frequency divisions being effected by an integrated circuit. The printed circuit associated with this whole comprises an annular plate surrounding the timepiece movement. An intermediary plate ensures the connection between the timepiece movement and the chronograph module. The transformation of a conventional timepiece movement into a chronograph watch is thus very easy, the chronograph module being able to be applied to very different timepiece movements, only the intermediary plate having to be different.

Description

La présente invention a pour objet une montre-chronographe.The present invention relates to a chronograph watch.

Une des difficultés de réalisation des mon­tres-chronographes réside dans le fait que chaque ca­libre doit être étudié pour lui-même et que, vu le nombre relativement limité des pièces à chronographe, leur coût en est fortement renchéri.One of the difficulties in producing chronograph watches lies in the fact that each caliber must be studied for itself and that, given the relatively limited number of chronograph parts, their cost is greatly increased.

De même, le constructeur qui envisage de transformer un mouvement de montre existant afin d'y adapter un chronographe, généralement associé à des indicateurs auxiliaires de minutes et d'heures, par exemple, est obligé d'adapter sa construction au ca­libre qu'il a choisi,de sorte que l'étude et la réa­lisation, en particulier l'outillage, ne conviennent que pour un calibre et doivent être répétés pour cha­que calibre à équiper.Likewise, the manufacturer who plans to transform an existing watch movement in order to adapt a chronograph, generally associated with auxiliary minutes and hours indicators, for example, is obliged to adapt its construction to the caliber it has chosen, so that the design and production, in particular the tools, are only suitable for one size and must be repeated for each size to be fitted.

Là encore, le coût en est considérablement augmenté.Again, the cost is greatly increased.

Le but de l'invention est de fournir un moyen d'adapter aisément un chronographe à un mouve­ment d'horlogerie, la partie chronographe de la mon­tre pouvant, sans modifications appréciables, être appliquée à un calibre ou à un autre.The object of the invention is to provide a means of easily adapting a chronograph to a clockwork movement, the chronograph part of the watch being able, without appreciable modifications, to be applied to one caliber or another.

Cela permet la réalisation de grandes sé­ries de mouvements ou modules chronographes utilisa­bles sur toutes sortes de calibres de mouvements d'hor­logerie différents.This allows the production of large series of movements or chronograph modules usable on all kinds of different timepiece movement calibers.

Ce but est atteint grâce aux moyens définis dans la revendication 1.This object is achieved by the means defined in claim 1.

La montre représentée, désignée d'une façon générale par 1, comprend un mouvement usuel d'horlo­gerie 2, rond dans le cas particulier, entraînant les aiguilles ordinaires de l'heure, à savoir une aiguille d'heures 3, une aiguille de minutes 4, et une aiguille de secondes au centre 5.The watch shown, generally designated by 1, comprises a usual clockwork movement 2, round in the particular case, driving the ordinary hour hands, namely an hour hand 3, a minute hand 4, and a seconds hand in the center 5.

Il s'agit d'un mouvement de montre classique, mécanique ou électronique, dont le remontage et la mise à l'heure, respectivement la mise à l'heure seule, s'ef­ fectuent à l'aide d'une tige 6 (fig. 3) portant une couronne de commande 7 (fig. 1).It is a classic watch movement, mechanical or electronic, whose winding and time setting, respectively time setting alone, is eff operate using a rod 6 (fig. 3) carrying a control ring 7 (fig. 1).

La boîte de cette monte comprend une carrure-lunette 8, une glace 9 et un fond 10 (fig. 4).The box of this mount includes a middle-bezel 8, a crystal 9 and a base 10 (fig. 4).

La montre 1 comporte en outre un mécanisme de chronographe porté par un bâti indépendant du bâti du mouvement 2. Le bâti de ce mouvement ou module de chronographe est représenté schématiquement à la fig. 2 où n'ont été représentées que les parties "planches" de ce bâti, à l'exclusion des parties for­mant entretoises, telles que piliers ou colonnes.Watch 1 further comprises a chronograph mechanism carried by a frame independent of the frame of movement 2. The frame of this movement or chronograph module is shown diagrammatically in FIG. 2 where only the "plank" parts of this frame have been shown, excluding the parts forming spacers, such as pillars or columns.

Ce bâti comprend une platine de base 11 et une platine supérieure 12, ainsi qu'un pont annulaire 13, constituant une cage en forme générale de cloche, qui vient coiffer le mouvement d'horlogerie 2, la par­tie annulaire de ce bâti ceinturant le mouvement 2. Une plaque intermédiaire 14, qui assure la liaison en­tre le mouvement d'horlogerie 2 et le module de chrono­graphe, est interposée entre eux. Le relief de sa face inférieure correspondra à celui de la platine du mou­vement de base 2. Ainsi, seule cette plaque intermédiai­ re 14 aura à être modifiée pour permettre d'appliquer le module de chronographe à un calibre ou à un autre.This frame includes a base plate 11 and an upper plate 12, as well as an annular bridge 13, constituting a cage in the general shape of a bell, which covers the clockwork movement 2, the annular part of this frame encircling the movement. 2. An intermediate plate 14, which provides the connection between the clockwork movement 2 and the chronograph module, is interposed between them. The relief of its lower face will correspond to that of the base plate of the base movement 2. Thus, only this intermediate plate re 14 will have to be modified to allow the chronograph module to be applied to one caliber or another.

La plaque intermédiaire 14, à laquelle est fixée la platine de base 11 du bâti du module de chro­nographe, se fixera elle-même à la platine du mouve­ment d'horlogerie 2 en lieu et place du cadran de celui-­ci, et par les mêmes moyens, par exemple à l'aide de pieds qu'elle présentera à cet effet. Ces pieds pour­ront ne servir qu'au positionnement (centrage, orienta­tion) de la plaque intermédiaire sur le platine du mou­vement 2, la fixation elle-même s'effectuant à l'aide de vis prenant dans les trous de la platine du mouve­ment prévus pour les clefs de fixation du mouvement dans la boîte. Ce sera alors les platines 11 ou 12 du bâti du module de chronographe qui porteront les clefs de fixa­tion de l'ensemble dans la boîte.The intermediate plate 14, to which the base plate 11 of the frame of the chronograph module is fixed, will itself be fixed to the plate of the clockwork movement 2 in place of the dial thereof, and by the same means, for example using feet that it will present for this purpose. These feet may only be used for positioning (centering, orientation) of the intermediate plate on the stage of movement 2, the fixing itself being carried out using screws taking in the holes of the stage of movement provided for the movement fixing keys in the box. It will then be the plates 11 or 12 of the frame of the chronograph module which will carry the keys for fixing the assembly in the box.

Le module de chronographe comporte trois in­dicateurs, à savoir une aiguille au centre 15 de chro­nographe, battant le 1/5 de seconde, une aiguille 16 comptant les heures, tournant en regard d'un tour d'heures 17 que présente le cadran de la montre, dési­ gné par 18, et une aiguille 19 de comptage des minutes, tournant en regard d'un tour de minutes 20 que pré­sente également le cadran 18. Celui-ci, reposant sur la platine 12 (figs. 4, 5 et 6), est fixé par des pieds 21 qui se prolongent jusqu'au niveau des platines 11 ou 12 (fig. 3).The chronograph module has three indicators, namely a hand at the center 15 of the chronograph, beating the 1/5 of a second, a hand 16 counting the hours, turning opposite a lap of hours 17 presented by the dial of the watch, desi hindered by 18, and a minute counting hand 19, rotating opposite a minute revolution 20 that also has dial 18. This, resting on the plate 12 (figs. 4, 5 and 6), is fixed by feet 21 which extend to the level of the plates 11 or 12 (fig. 3).

Tous ces indicateurs, aiguille de chronogra­phe et compteurs, sont entraînés de façon propre, c'est-à-dire indépendamment du mouvement d'horlogerie 2, le module de chronographe, électrique, étant auto­nome. Sa mise en marche et son arrêt sont commandés par un poussoir 22.All these indicators, chronograph hand and counters, are driven in their own way, that is to say independently of watch movement 2, the chronograph module, electric, being autonomous. Its starting and stopping are controlled by a pusher 22.

A cet effet, le pont annulaire 13 du bâti du module de chronographe porte trois moteurs électri­ques 23, 24 et 25 entraînant respectivement les trois aiguilles 15, 16 et 19. Ces trois moteurs 23, 24 et 25 sont pilotés par un oscillateur à quartz 26 et sont alimentés par une pile commune 27 (fig. 3), les divi­sions de fréquences désirées étant assurées par un cir­cuit intégré 28. Le module comporte un circuit imprimé 29 dont la plaque, annulaire, est superposée au pont annulaire 13 du bâti de ce module.For this purpose, the annular bridge 13 of the frame of the chronograph module carries three electric motors 23, 24 and 25 respectively driving the three hands 15, 16 and 19. These three motors 23, 24 and 25 are controlled by a quartz oscillator 26 and are powered by a common battery 27 (fig. 3), the desired frequency divisions being ensured by an integrated circuit 28. The module comprises a printed circuit 29, the annular plate of which is superimposed on the annular bridge 13 of the frame of this module.

Ainsi, les trois moteurs, l'oscillateur à quartz, la pile, le circuit intégré avec, de surcroît, un condensateur variable (trimmer), indiqué en 30 à la fig. 3, sont tous situés autour du mouvement d'hor­logerie 2.Thus, the three motors, the quartz oscillator, the battery, the integrated circuit with, in addition, a variable capacitor (trimmer), indicated at 30 in fig. 3, are all located around watch movement 2.

L'aiguille de chronographe 15 est entraînée par le moteur 23 de la façon suivante :The chronograph hand 15 is driven by the motor 23 as follows:

Le rotor du moteur 23, désigné par 31 (figs 3 et 5), est solidaire d'un pignon 32 entraînant, par l'intermédiaire de deux mobiles 33 et 34, une roue 35 reliée, par l'intermédiaire d'un accouplement à friction comprenant une rondelle cambrée 36, à un pi­gnon 37 en prise avec une roue 38 solidaire d'un man­chon ou canon 39 entourant la roue à canon des heures, désignée par 40 du mouvement d'horlogerie 2 (figs. 2 et 4). Ce canon 39 porte l'aiguille de chronographe 15. Tout le train d'en­grenages reliant le rotor du moteur 23 à l'aiguille 15 est ainsi porté par la partie centrale du bâti du module de chronogra­phe, recouvrant le mouvement d'horlogerie 2, et non pas par la partie annulaire de ce bâti, ceinturant le mou­vement.The rotor of the motor 23, designated by 31 (figs 3 and 5), is integral with a pinion 32 driving, by means of two mobiles 33 and 34, a wheel 35 connected, by means of a coupling to friction comprising a cambered washer 36, to a pinion 37 engaged with a wheel 38 secured to a sleeve or barrel 39 surrounding the hour barrel wheel, designated by 40 of the clockwork movement 2 (figs. 2 and 4). This barrel 39 carries the chronograph hand 15. The entire gear train connecting the rotor of the motor 23 to the hand 15 is thus carried by the central part of the frame of the chronograph module, covering the clockwork movement 2, and not by the annular part of this frame, surrounding the movement.

La friction entre la roue 35 et le pignon 37 a pour but de permettre la remise à zéro manuelle de l'aiguille 15 sans que soit sollicité le rotor du moteur.The friction between the wheel 35 and the pinion 37 is intended to allow manual reset of the needle 15 without being requested from the motor rotor.

En vue de cette remise à zéro, la roue 38 solidaire du canon 39 est en prise avec une roue 41 (fig. 3) solidaire d'un coeur de remise à zéro 42 avec lequel coopère un marteau de remise à zéro 43, dont une très petite par­tie seulement a été représentée à la fig. 3, commandé par un poussoir de remise à zéro 44 agissant sur une partie re­pliée à angle droit 43a de la bascule présentant le marteau 43 (figs. 1 et 4). Il est à remarquer que la correction de l'aiguille 15 ne pourrait guère se faire électroniquement, par l'intermédiaire du moteur d'entraînement 23, étant donné que, cette aiguille battant le 1/5 de seconde, l'opération durerait alors trop longtemps. Par contre, si le mécanisme était agencé de manière que l'aiguil­le 15 batte la seconde, alors une remise à zéro élec­tronique pourrait être envisagée.For the purpose of this reset, the wheel 38 secured to the barrel 39 is engaged with a wheel 41 (FIG. 3) secured to a reset heart 42 with which a reset hammer 43 cooperates, including one only a very small part has been shown in fig. 3, controlled by a reset push-button 44 acting on a part folded at a right angle 43 a of the rocker having the hammer 43 (figs. 1 and 4). It should be noted that the correction of the needle 15 could hardly be done electronically, via the drive motor 23, since, since this needle beats 1/5 of a second, the operation would then take too long long time. By cons, if the mechanism was arranged so that the needle 15 beats the second, then an electronic reset could be considered.

L'aiguille 19 du compteur des minutes est entraînée par le moteur 25 de la façon suivante :The hand 19 of the minute counter is driven by the motor 25 as follows:

Le rotor, désigné par 48 (fig. 6), du mo­teur 25 est solidaire d'un pignon 49 entraînant, par l'intermédiaire d'un mobile 50, une roue 51 dont l'ar­bre, désigné par 52, porte l'aiguille 19.The rotor, designated by 48 (fig. 6), of the motor 25 is integral with a pinion 49 driving, by means of a mobile 50, a wheel 51 whose shaft, designated by 52, carries the needle 19.

L'aiguille 16 du compteur des heures est entraînée par le moteur 24 de façon analogue :The hand 16 of the hour counter is driven by the motor 24 in a similar fashion:

Le rotor, désigné par 53 (fig. 3), du moteur 24 est solidaire d'un pignon 54 entraînant, par l'in­termédiaire d'un mobile 55, une roue 56 dont l'arbre, désigné par 57, porte l'aiguille 16.The rotor, designated by 53 (fig. 3), of the motor 24 is integral with a pinion 54 driving, by means of a mobile 55, a wheel 56 whose shaft, designated by 57, carries the needle 16.

La remise à zéro des aiguilles 16 du compteur des heures et 19 des minutes s'effectuera électronique­ment, commandée par le poussoir 44. Ainsi, la remise à zéro des différents indicateurs du chronographe est mixte, l'aiguille de chronographe 15 étant remise à zéro mécaniquement et les aiguilles des compteurs 16 et 19 l'étant électroniquement. Il est à remarquer que la remise à zéro des compteurs pourrait également s'effec­ tuer mécaniquement, à l'aide de coeurs qui seraient alors actionnés par des marteaux qui pourraient être constitués par des pannes supplémentaires de la même bascule que celle présentant le marteau 43.The reset of the hands 16 of the hour and 19 minute counter will be carried out electronically, controlled by the push-button 44. Thus, the reset of the various chronograph indicators is mixed, the chronograph hand 15 being reset mechanically and the hands of the counters 16 and 19 being electronically. Note that resetting the counters could also take place. mechanically kill, using hearts which would then be actuated by hammers which could consist of additional purlins of the same scale as that presenting the hammer 43.

La montre décrite et représentée comprend en outre un indicateur des quantièmes constitué par une aiguille 58 tournant en regard d'un tour de quan­tièmes 59 porté par le cadran 18, et un indicateur des phases de lune constitué par un disque 60 visible à travers un guichet 61 du cadran.The watch described and shown further comprises a date indicator constituted by a hand 58 rotating opposite a date turn 59 carried by the dial 18, and an indicator of the moon phases constituted by a disc 60 visible through a window 61 of the dial.

Ces deux indicateurs sont entraînés par le mouvement 2 à partir de la roue à canon des heures 40 qui commande une roue 62 (fig. 3) solidaire de deux pignons 63 et 64 en prise avec deux roues coaxiales 65 et 66, respectivement. La roue 62 et les roues 65 et 66 sont portées par la plaque intermédiaire 14. La roue 65 porte l'aiguille 58 des quantièmes alors que la roue 66 porte le disque 60 des phases de lune. La plaque intermédiaire 14 pourrait porter d'autres indicateurs encore.These two indicators are driven by movement 2 from the hour wheel 40 which controls a wheel 62 (fig. 3) secured to two pinions 63 and 64 engaged with two coaxial wheels 65 and 66, respectively. The wheel 62 and the wheels 65 and 66 are carried by the intermediate plate 14. The wheel 65 carries the needle 58 of the date while the wheel 66 carries the disc 60 of the moon phases. The intermediate plate 14 could carry still other indicators.

Il est à remarquer que le terme "annulaire" utilisé pour définir la forme particulière du bâti du module de chronographe n'implique pas que ce bâti soit obligatoirement circulaire. En effet, le mouvement de base pourrait être de forme, le bâti annulaire du module de chronographe étant alors de forme corres­pondante de façon à le ceinturer.It should be noted that the term "annular" used to define the particular shape of the frame of the chronograph module does not imply that this frame is necessarily circular. Indeed, the basic movement could be in shape, the annular frame of the chronograph module then being of corresponding shape so as to surround it.

Grâce à la présente disposition, le mouve­ment de base 2 ne subit pas d'autres modifications, pour être complété par un chronographe, que l'allonge­ment du canon 40 de la roue des heures, de la chaussée, désignée par 67, portant l'aiguille 4 des minutes, et du tigeron 68 de l'aiguille 5 de la seconde au centre.Thanks to this arrangement, the basic movement 2 does not undergo any other modifications, to be completed by a chronograph, than the lengthening of the barrel 40 of the hour wheel, of the roadway, designated by 67, bearing the 4 minutes hand, and tigeron 68 of 5 seconds hand in the center.
