Abstract

The chronographic watch has an electronic watch movement (1) for displaying the hour, the minute and the second (2) and an autonomous chronographic mechanism (9-13) in modular form. The electronic watch movement and the chronographic module are produced using the same standard and relatively low-cost electronic components. The chronographic module is arranged either beside the watch movement (1) or below it. These measures result in an inexpensive chronographic watch. <IMAGE>

Description

La présente invention concerne une montre chronographe électronique. Une telle montre permet, en plus de l'affichage normal de l'heure, de mesurer des temps habituellement compris entre des fractions de seconde et quelques heures. Ceci à l'aide d'un mécanisme de comp­tage du temps dérivé soit du train de rouage d'une montre mécanique ou électronique, soit à partir de moteurs pilotés par l'oscillateur et le circuit intégré d'une montre électronique. Dans les réalisations connues de ce type de montre, le mouvement de montre et le mécanisme chronographe sont construits l'un en fonction de l'autre et totalement imbriqués l'un dans l'autre, ce qui conduit à des réalisations onéreuses.The present invention relates to an electronic chronograph watch. Such a watch allows, in addition to the normal time display, to measure times usually between fractions of a second and a few hours. This using a time counting mechanism derived either from the train of a mechanical or electronic watch, or from motors controlled by the oscillator and the integrated circuit of an electronic watch. In the known embodiments of this type of watch, the watch movement and the chronograph mechanism are constructed as a function of the other and completely nested one inside the other, which leads to expensive embodiments.

En conséquence, le but de la présente invention est de réaliser une montre chronographe électronique facile à fabriquer et bon marché. Pour atteindre ce but, la montre selon l'invention est réalisée comme décrit dans la revendication 1. Par le fait que le mécanisme de chronographe est totalement indépendant (éventuellement à l'exception de la source d'énergie) du mouvement de montre et qu'il est réalisé sous forme d'un module séparé, il peut être disposé et assemblé sans diffi­culté soit à côté, soit en dessous du mouvement de montre, ce qui facilite le montage. D'autre part, cette conception permet d'utiliser sans autre les mêmes composants électroniques standards et de prix parti­culièrement bas pour le mouvement de la montre et pour le module chronographe. La combinaison de ces mesures conduit à une montre chronographe bon marché.Consequently, the aim of the present invention is to produce an electronic chronograph watch which is easy to manufacture and inexpensive. To achieve this object, the watch according to the invention is produced as described in claim 1. By the fact that the chronograph mechanism is completely independent (possibly with the exception of the energy source) of the watch movement and that 'it is produced in the form of a separate module, it can be arranged and assembled without difficulty either next to or below the watch movement, which facilitates assembly. On the other hand, this design allows the same standard electronic components and particularly low prices to be used without other for the movement of the watch and for the chronograph module. The combination of these measures leads to an inexpensive chronograph watch.

L'invention va être décrite plus en détail ci-aprés, à l'aide d'un exemple d'exécution et du dessin dans lequel:

  • La figure 1 illustre le principe de base de l'inven­tion, et
  • La figure 2 illustre un exemple d'un mécanisme de chronographe selon l'invention.
The invention will be described in more detail below, with the aid of an exemplary embodiment and the drawing in which:
  • FIG. 1 illustrates the basic principle of the invention, and
  • FIG. 2 illustrates an example of a chronograph mechanism according to the invention.

La figure 1 illustre une montre 15 selon l'invention, comportant en son centre un mouvement de montre électro­nique 1 avec des aiguilles d'heure, minute et seconde 2, une tige de mise à l'heure 3 et une source d'énergie 4. Les périphéries du mouvement 1 et de la montre 15 déterminent entre elles un anneau 6 extérieur au mouve­ment qui est utilisé pour y loger un mécanisme de chronographe autonome sous forme de module alimenté par une source d'énergie 5 propre à ce mécanisme. Cependant, le mécanisme de chronographe ne nécessite pas obliga­toirement une propre source d'énergie et il peut aussi être alimenté par la source d'énergie 4 du mouvement de montre 1. D'autre part, il n'est pas obligatoire de loger le module chronographe dans l'anneau 6, ce module pouvant aussi être disposé p. ex. sous le mouvement 1. La figure 1 montre encore des boutons-­poussoirs 7 et 8 pour la commande de l'enclenchement, l'arrêt et la remise à zéro du chronographe.FIG. 1 illustrates a watch 15 according to the invention, comprising in its center an electronic watch movement 1 with hour, minute and second hands 2, a time-setting rod 3 and a power source 4 The peripheries of the movement 1 and of the watch 15 determine between them a ring 6 external to the movement which is used to house an autonomous chronograph mechanism in the form of a module powered by an energy source 5 specific to this mechanism. However, the chronograph mechanism does not necessarily require its own energy source and it can also be powered by the energy source 4 of the watch movement 1. On the other hand, it is not compulsory to house the module chronograph in ring 6, this module can also be arranged on p. ex. under movement 1. FIG. 1 also shows push-buttons 7 and 8 for controlling the engagement, stopping and resetting of the chronograph.

La figure 2 montre un mécanisme chronographe autonome sous forme de module selon l'invention. Dans l'exemple illustré, et dans un but de simplification, le chrono­graphe ne comporte qu'un seul compteur (13). Le module comprend un résonateur à quartz 9, un circuit intégré 10 et un moteur 11 entraînant un rouage 12 aboutissant à un affichage analogique à aiguille 13. Une source d'énergie 14 assure une alimentation indépendante du module chronographe. On reconnaît les organes 7 et 8 de commande des fonctions du chronographe.FIG. 2 shows an autonomous chronograph mechanism in the form of a module according to the invention. In the example illustrated, and for the sake of simplification, the chronograph has only one counter (13). The module comprises a quartz resonator 9, an integrated circuit 10 and a motor 11 driving a gear train 12 leading to an analog display with a needle 13. An energy source 14 provides a power supply independent of the chronograph module. We recognize the organs 7 and 8 for controlling the chronograph functions.

Un chronographe avec au moins deux affichages peut être réalisé soit à l'aide d'au moins deux moteurs 11, soit à l'aide d'éléments mécaniques respectifs tels qu'engrenages ou cames et leviers à partir du rouage 12 du premier affichage 13.A chronograph with at least two displays can be produced either using at least two motors 11, or using respective mechanical elements such as gears or cams and levers from the gear train 12 of the first display 13 .

Comme variante, il est possible d'afficher au moins une partie des temps chronométrés par voie digitale. Dans ce cas, il est prévu au moins un affichage digital commandé de manière en soi connue par le circuit intégré 10 du module chronographe. Un tel affichage digital peut aussi être utilisé hors des fonctions chronographe pour afficher d'autres valeurs, p.ex. l'indication de la date.As a variant, it is possible to display at least part of the timed times digitally. In this case, there is provided at least one digital display controlled in a manner known per se by the integrated circuit 10 of the chronograph module. Such a digital display can also be used outside of the chronograph functions to display other values, eg the date indication.
