Abstract

The setting system of this invention includes a contactor provided with a blade adapted to come into repeated contact with a contact stud thereby to act on an electrical circuit. The contactor is operated by a stem bearing a crown and has a lock which prevents the blade from coming into accidental contact with the stud (for instance following a shock) when said stem is in its pushed-in rest position.

Description

L'invention est relative à un dispositif de correction pour pièce d'horlogerie comportant une tige à couronne susceptible d'être amenée d'une position de repos enfoncée à une position de travail tirée et un contacteur comprenant une lame susceptible d'entrer en contact répétés avec au moins un plot de contact pour agir sur un circuit électrique quand la tige est entraînée en rotation dans sa position tirée.The invention relates to a correction device for a timepiece comprising a crown rod capable of being brought from a depressed rest position to a pulled working position and a contactor comprising a blade capable of coming into contact repeated with at least one contact pad to act on an electrical circuit when the rod is rotated in its pulled position.

Plusieurs dispositifs de correction répondant à la définition générique ci-dessus sont connus.Several correction devices meeting the generic definition above are known.

Le brevet US-A-3 841 081 montre une lame 6 qui coopère avec les dents d'une roue à cliquet 4 elle-même entraînée en rotation par une tige 1. Quand on fait tourner la tige la lame entre en contacts répétés avec un plot de contact 10. Comme les quatre dents de la roue à cliquet sont très espacées l'une de l'autre, on conçoit que la lame, qui est pourvue d'une certaine élasticité, puisse venir toucher intempestivement le plot de contact, donnant ainsi une impulsion électrique non désirée et, partant, un signal de correction non voulu si un choc est appliqué à la pièce d'horlogerie.US-A-3 841 081 shows a blade 6 which cooperates with the teeth of a ratchet wheel 4 itself rotated by a rod 1. When the rod is rotated, the blade comes into repeated contact with a contact pad 10. As the four teeth of the ratchet wheel are very widely spaced from each other, it is conceivable that the blade, which is provided with a certain elasticity, can accidentally touch the contact pad, giving thus an unwanted electrical impulse and hence an unwanted correction signal if a shock is applied to the timepiece.

Le dispositif de correction pour pièce d'horlogerie électronique décrit dans le brevet CH-A-642 220 comporte également un bras 25 qui, lorsqu'une tige-couronne 1 est entraînée en rotation, peut entrer en contacts répétés soit avec un première borne 29 soit avec une seconde borne 30 suivant le sens de rotation de la tige. Dans cette exécution aussi le bras peut entrer en contact intempestif avec l'une ou l'autre des bornes mentionnées et provoquer ainsi des corrections non désirées. Pour remédier à cet inconvénient la construction citée propose un dispositif interrupteur supplémentaire 33 qui n'est enclenché que lorsque la tige se trouve en position de correction, inhibant ainsi toute correction indésirable quand cette tige est en position de repos. Cette disposition a cependant le désavantage de compliquer la construction et de diminuer la fiabilité de fonctionnement de la pièce d'horlogerie.The correction device for an electronic timepiece described in patent CH-A-642,220 also includes an arm 25 which, when a crown stem 1 is rotated, can come into repeated contact with either a first terminal 29 either with a second terminal 30 according to the direction of rotation of the rod. In this embodiment also the arm can come into untimely contact with one or the other of the mentioned terminals and thus cause unwanted corrections. To remedy this drawback, the cited construction offers an additional switch device 33 which is engaged only when the rod is in the correction position, thus inhibiting any undesirable correction when this rod is in the rest position. This arrangement has the disadvantage, however, of complicating the construction and of reducing the operating reliability of the timepiece.

Pour se soustraire aux inconvénients cités, la présente invention fait appel à un verrou commandé par la tige et arrangé pour limiter la course de la lame du contacteur quand ladite tige est en position enfoncée, de manière à empêcher ladite lame d'entrer en contact avec ledit plot de contact quand un choc est appliqué à la pièce d'horlogerie.To avoid the aforementioned drawbacks, the present invention uses a lock controlled by the rod and arranged to limit the travel of the contactor blade when said rod is in the depressed position, so as to prevent said blade from coming into contact with said contact pad when a shock is applied to the timepiece.

L'invention sera mieux comprise maintenant en s'aidant d'un exemple de construction où est mis en oeuvre le dispositif selon ladite invention, exemple illustré par le dessin dans lequel:

  • La figure 1 est une vue en plan du dispositif de correction selon l'invention où la tige est disposée en position de repos enfoncée et où le verrou se trouve en position active.
  • La figure 2 est la même vue en plan que celle de la figure 1, mais où la tige est en position de travail tirée et le verrou en position escamotée, la lame du contacteur étant en contact avec un premier plot.
  • La figure 3 présente une situation semblable à celle de la figure 2 mais dans laquelle la lame du contacteur est en contact avec un second plot et
  • La figure 4 est un schéma de circuit électronique auquel est relié le dispositif de correction montré dans les figures 1 à 3.
The invention will now be better understood with the aid of an example of construction in which the device according to said invention is used, example illustrated by the drawing in which:
  • Figure 1 is a plan view of the correction device according to the invention where the rod is disposed in the depressed rest position and where the lock is in the active position.
  • Figure 2 is the same plan view as that of Figure 1, but where the rod is in the pulled working position and the latch in the retracted position, the contactor blade being in contact with a first stud.
  • FIG. 3 presents a situation similar to that of FIG. 2 but in which the contactor blade is in contact with a second pad and
  • FIG. 4 is a diagram of the electronic circuit to which the correction device shown in FIGS. 1 to 3 is connected.

Les trois premières figures montrent une pièce d'horlogerie comportant une tige à couronne 1 qui peut être disposée selon trois positions axiales définies par trois gorges 2, 3 et 4 et un sautoir de cran- tage 5. La pièce porte encore un anneau 6 pourvu d'une denture intérieure 7 et d'indications 8. Cet anneau, qui est semblable à l'anneau de quantième d'une montre, est entraîné en rotation si on dispose la tige en position médiane où le sautoir 5 coopère avec la gorge 3 (figures 2 et 3) et si on fait tourner cette tige dans un sens anti-horaire. Dans cette position en effet, un pignon 9 qui fait partie intégrante de la tige 1 est en prise avec une roue 10 qui entraîne à son tour les roues 11 et 12 et finalement l'anneau 6 par sa denture 7.The first three figures show a timepiece comprising a crowned rod 1 which can be arranged in three axial positions defined by three grooves 2, 3 and 4 and a notched jumper 5. The piece also carries a ring 6 provided an internal toothing 7 and indications 8. This ring, which is similar to the date ring of a watch, is rotated if the rod is placed in the middle position where the jumper 5 cooperates with the groove 3 (Figures 2 and 3) and if we rotate this rod counterclockwise. In this position, in fact, a pinion 9 which is an integral part of the rod 1 is engaged with a wheel 10 which in turn drives the wheels 11 and 12 and finally the ring 6 by its teeth 7.

Lorsque la tige 1 se trouve en position neutre enfoncée où le sautoir 5 coopère avec la gorge 2 comme le montre la figure 1, le pignon de tige 9 ne se trouve plus en prise avec la roue 10 et l'anneau 6 ne peut plus être entraîné en rotation.When the rod 1 is in the depressed neutral position where the jumper 5 cooperates with the groove 2 as shown in FIG. 1, the rod pinion 9 is no longer engaged with the wheel 10 and the ring 6 can no longer be driven in rotation.

Les trois figures montrent encore que la tige 1 peut être déplacée dans une seconde position tirée extrême pour laquelle le sautoir 5 pénètre dans la gorge 4. Il s'agit là d'une position de mise à l'heure du garde-temps qui est réalisée de façon connue et qui n'a pas besoin d'être décrite ici.The three figures also show that the rod 1 can be moved into a second extreme pulled position for which the jumper 5 enters the groove 4. This is a position for setting the time of the timepiece which is carried out in a known manner and which need not be described here.

Le mécanisme d'horlogerie pris en exemple ici est employé pour réaliser une fonction de minuterie (ou de timer) utilisée seule ou incorporée dans une montre indiquant également l'heure de façon classique. Dans l'exemple on se sert de l'anneau 6 non pour indiquer le quantième mais pour afficher une période qui lorsqu'elle sera écoulée enclenchera un avertisseur sonore. Ainsi l'anneau 6 au lieu d'être entraîné par le rouage du garde-temps, est actionné par le porteur de la montre directement au moyen de la tige à couronne 1.The clock mechanism taken as an example here is used to perform a timer function (or timer) used alone or incorporated in a watch also indicating the time in a conventional manner. In the example, the ring 6 is used not to indicate the date but to display a period which, when it has elapsed, will activate an audible warning. Thus, the ring 6 instead of being driven by the train of the timepiece, is actuated by the wearer of the watch directly by means of the crown rod 1.

Il est donc possible au moyen de la tige 1 d'amener l'anneau 6 dans l'une quelconque de trente-et-une positions, ce nombre étant choisi en fonction des positions qui sont habituelles dans une pièce d'horlogerie pourvue d'un indicateur de quantième. Ici les indications 8 portées par l'anneau représentent des périodes en minutes s'échelonnant de cinq minutes en cinq minutes. Les indications 8 apparaissent à tour de rôle au travers d'un guichet non représenté situé généralement à 3 heures de la pièce d'horlogerie.It is therefore possible by means of the rod 1 to bring the ring 6 into any one of thirty-one positions, this number being chosen as a function of the positions which are usual in a timepiece provided with a date indicator. Here the indications 8 carried by the ring represent periods in minutes ranging from five minutes to five minutes. The indications 8 appear in turn through a window (not shown) generally located 3 hours from the timepiece.

Pour prendre un example de réglage du mécanisme en question, on suppose qu'il est 9 heures et que le porteur de la montre désire être averti à 11 heures soit 2 heures plus tard. Il amènera la tige 1 en position médiane, fera tourner la tige jusqu'a ce que l'indication 0 apparaisse à travers le guichet, puis continuera à tourner la tige jusqu'à ce que l'indication 2h00 apparaisse à travers le guichet, et enfin repoussera la tige en position neutre enfoncée.To take an example of setting the mechanism in question, it is assumed that it is 9 am and that the wearer of the watch wishes to be notified at 11 am, ie 2 hours later. It will bring rod 1 to the middle position, rotate the rod until the indication 0 appears through the window, then continue to rotate the rod until the indication 2h00 appears through the window, and finally push back the rod in the neutral position pressed.

Pour mettre en oeuvre la fonction de minuterie désirée, la pièce d'horlogerie comporte un contacteur 13 muni d'une lame 14 susceptible d'entrer en contacts répétés avec au moins un plot de contact 15 pour agir sur un contact électrique quand la tige est entraînée en rotation dans sa position tirée.To implement the desired timer function, the timepiece includes a contact tor 13 provided with a blade 14 capable of coming into repeated contact with at least one contact pad 15 to act on an electrical contact when the rod is rotated in its pulled position.

Selon l'invention, la pièce d'horlogerie comprend un verrou 16 qui est commandé par la tige 1 et qui est arrangé pour limiter la course de la lame 14 quand la tige 1 est en position enfoncée, de manière à empêcher ladite lame d'entrer en contact avec le plot 15 quand un choc est appliqué à la pièce d'horlogerie. Cette situation est représentée en figure 1. Le verrou 16 présente l'aspect d'une pièce plate, allongée et munie à sa première extrémité d'un bord replié 17 qui constitue une butée limitant la course de la lame. Le verrou est guidé longitudinalement par un autre bord replié 18 qui coopère avec une ouverture 19 pratiquée dans le mouvement de la montre. Le verrou est appliqué constamment par sa seconde extrémité également repliée 20 sur le pignon de tige 9 grâce à un ressort 21 qui agit sur une butée 22 levée dans le verrou 16. Le verrou est appliqué sur une plaque de maintien 23 qui fait partie du mouvement et est maintenu dans le sens de la hauteur d'une part par le ressort 21 et d'autre part par une languette 24.According to the invention, the timepiece comprises a lock 16 which is controlled by the rod 1 and which is arranged to limit the stroke of the blade 14 when the rod 1 is in the depressed position, so as to prevent said blade from come into contact with the stud 15 when a shock is applied to the timepiece. This situation is shown in Figure 1. The lock 16 has the appearance of a flat piece, elongated and provided at its first end with a folded edge 17 which constitutes a stop limiting the stroke of the blade. The lock is guided longitudinally by another folded edge 18 which cooperates with an opening 19 made in the movement of the watch. The lock is constantly applied by its second end also folded back 20 on the rod pinion 9 by means of a spring 21 which acts on a stop 22 lifted in the lock 16. The lock is applied on a holding plate 23 which is part of the movement and is held in the height direction on the one hand by the spring 21 and on the other hand by a tongue 24.

Ainsi comme le montre la figure 1 où la tige se trouve en position de repos, la lame 14 du contacteur 13 est empêchée de venir toucher intempestivement le plot 15 si un choc est appliqué à la pièce d'horlogerie.Thus, as shown in FIG. 1 where the rod is in the rest position, the blade 14 of the contactor 13 is prevented from accidentally touching the stud 15 if a shock is applied to the timepiece.

Si l'on se reporte maintenant à la figure 2, on aperçoit que la tige 1 est dans sa position de travail tirée. En tirant la tige, le verrou 16 s'est déplacé vers le haut de la figure, entraîné qu'il a été par le ressort 21, qui applique toujours la seconde extrémité 20 dudit verrou contre le pignon de tige 9. La lame 14 du contacteur 13 peut alors venir en contact avec le plot 15.If we now refer to Figure 2, we see that the rod 1 is in its pulled working position. By pulling the rod, the latch 16 has moved upwards in the figure, driven as it has been by the spring 21, which always applies the second end 20 of said latch against the rod pinion 9. The blade 14 of the contactor 13 can then come into contact with stud 15.

Comme le montre le dessin, et selon une caractéristique dépendante de l'invention, le contacteur 13 est une bascule pouvant pivoter autour d'un axe fixe 25, ladite bascule comprenant, outre la lame de contact 14, un palpeur 26 coopérant avec une pièce dentée commandée par la tige, en l'occurence ici avec la denture intérieure 7 de l'anneau 6. Le contacteur comporte encore un ressort de rappel 27 qui appuie le palpeur 26 contre la denture de l'anneau. De cette façon la lame 14 vient en contact électrique avec le plot 15 chaque fois que le palpeur passe sur une dent 7 de l'anneau (figure 2), de même qu'elle se sépare dudit plot chaque fois que ledit palpeur se trouve situé dans un creux 28 séparant deux dents (figure 1). Dans le cas illustré par la figure 2, on voit que le verrou 16 est disposé hors du champ d'action de la lame et que la lame 14 passe d'une position de contact à une position où ce contact est interrompu.As shown in the drawing, and according to a characteristic dependent on the invention, the switch 13 is a rocker which can pivot around a fixed axis 25, said rocker comprising, in addition to the contact blade 14, a feeler 26 cooperating with a part toothed controlled by the rod, in this case here with the internal toothing 7 of the ring 6. The contactor further comprises a return spring 27 which presses the feeler 26 against the toothing of the ring. In this way the blade 14 comes into electrical contact with the pad 15 each time the probe passes over a tooth 7 of the ring (FIG. 2), just as it separates from said pad each time that said probe is located in a hollow 28 separating two teeth (Figure 1). In the case illustrated by FIG. 2, it can be seen that the latch 16 is disposed outside the field of action of the blade and that the blade 14 passes from a contact position to a position where this contact is interrupted.

Selon une autre caractéristique dépendante de l'invention, le dispositif comporte encore une plaque 29 découpée et pliée de telle façon qu'elle présente un ressort de sautoir 30 pour le positionnement de l'anneau 6 et le ressort de rappel 21 dont il a été question plus haut pour appuyer le verrou 16 contre la tige 1. La plaque 29 est fixée au mouvement par des goupilles 31. Le dessin montre par ailleurs qu'on découpe dans la plaque 29 la languette 24 dont il a été question plus haut et qui sert à maintenir le verrou 16.According to another characteristic dependent on the invention, the device also includes a plate 29 cut and folded in such a way that it has a jumper spring 30 for positioning the ring 6 and the return spring 21 from which it has been question above to press the latch 16 against the rod 1. The plate 29 is fixed to the movement by pins 31. The drawing also shows that the tongue 24 which has been discussed above and which is cut out from the plate 29 used to hold latch 16.

Enfin selon une autre caractéristique dépendante de l'invention, on voit au dessin que l'anneau 6 comporte une encoche 32 disposée entre deux dents 7 qui est plus profonde que les creux 28 disposés entre les autres dents. La figure 3 montre que lorsque le palpeur 26 du contacteur 13 se trouve au fond de l'encoche 32, la lame 14 vient en contact électrique avec un second plot 33. Ainsi fa lame 14, selon que le palpeur est au fond de l'encoche 32, au fond d'un creux 28 ou au sommet d'une dent 7, vient toucher le plot 33, se trouve à mi-distance entre les plots 33 et 15 ou vient toucher le plot 15, respectivement. Dans la construction montrée au dessin, on voit qu'il n'y a pas de risque que la lame 14 vienne toucher intempestivement le plot 33 retenue qu'elle est par le palpeur 26. On pourrait cependant imaginer dans ce cas un second verrou empêchant la lame 14 de se mouvoir dans la direction du plot 33, second verrou qui serait également commandé par la tige au moyen d'une commande à bras de levier.Finally, according to another characteristic dependent on the invention, it can be seen in the drawing that the ring 6 has a notch 32 disposed between two teeth 7 which is deeper than the recesses 28 disposed between the other teeth. FIG. 3 shows that when the feeler 26 of the contactor 13 is at the bottom of the notch 32, the blade 14 comes into electrical contact with a second stud 33. Thus the blade 14, depending on whether the feeler is at the bottom of the notch 32, at the bottom of a hollow 28 or at the top of a tooth 7, comes to touch the pad 33, is located midway between the pads 33 and 15 or comes to touch the pad 15, respectively. In the construction shown in the drawing, it can be seen that there is no risk of the blade 14 inadvertently touching the stud 33 retained by the feeler 26. However, one could imagine in this case a second lock preventing the blade 14 to move in the direction of the stud 33, the second lock which would also be controlled by the rod by means of a lever control.

Chaque fois que la lame 14 vient en contact avec le plot 15, dit aussi plot d'incrémentation, on donne naissance à une impulsion électrique qui est prise en compte par un circuit électronique selon un processus qui sera décrit ci-après. Le nombre d'impulsions recueillies est ainsi représentatif de la position de l'anneau 6 et donc de la période choisie par le porteur de la montre et ceci à partie d'un point de départ signalé par la mise à zéro de l'anneau, cette mise à zéro ayant lieu lorsque le palpeur 26 pénètre dans l'encoche 32, provoquant ainsi le contact de la lame 14 avec le plot 33, dit aussi plot de remise à zéro.Each time the blade 14 comes into contact with the pad 15, also known as the increment pad, an electrical pulse is given birth which is taken into account by an electronic circuit according to a process which will be described below. The number of pulses collected is thus representative of the position of the ring 6 and therefore of the period chosen by the wearer of the watch and this starting from a starting point indicated by the zeroing of the ring, this zeroing taking place when the probe 26 enters the notch 32, thus causing contact of the blade 14 with the pad 33, also called reset pad.

La construction présentée au dessin est arrangée pour que l'anneau ne puisse être entraîné que dans un seul sens, ici lorsque la tige-couronne 1 est entraînée en rotation dans le sens anti-horaire. Pour cela la roue 11 est montée baladeuse entre les roues 10 et 12. Comme on le voit sur la figure 2, la roue 11 est en prise avec les roues 10 et 12 quand la tige 1 est entraînée dans le sens anti-horaire. Par contre cette roue 11 occupe la position 11' si la tige est entraînée dans le sens horaire.The construction presented in the drawing is arranged so that the ring can only be driven in one direction, here when the stem-crown 1 is rotated counterclockwise. For this, the wheel 11 is mounted portable between the wheels 10 and 12. As can be seen in FIG. 2, the wheel 11 is engaged with the wheels 10 and 12 when the rod 1 is driven counterclockwise. Against by this wheel 11 occupies position 11 'if the rod is driven clockwise.

La figure 4 représente un schéma électrique d'un circuit qui peut être utilisé dans la montre représentée aux figures 1 à 3. Ce circuit comporte une partie 40 spécifiquement destinée à l'indication de l'heure officielle et une partie 50 qui assure la fonction minuterie en coopération avec la tige 1, l'anneau 6 et la lame 14 du contacteur 13.FIG. 4 represents an electrical diagram of a circuit which can be used in the watch shown in FIGS. 1 to 3. This circuit comprises a part 40 specifically intended for indicating the official time and a part 50 which performs the function timer in cooperation with the rod 1, the ring 6 and the blade 14 of the contactor 13.

De façon classique, la partie 40 comporte un oscillateur à quartz 41 fournissant un signal dont la fréquence est d'environ 32 kHz. Cet oscillateur est connecté à un diviseur 42 dont l'une des sorties 43 est reliée à la partie 50 du circuit, le signal apparaissant à cette sortie étant constitué par un train d'impulsions dont les impulsions sont espacées de cinq minutes (0,003 Hz), tout au moins dans l'exemple décrit ici. De façon classique, le diviseur est relié à un circuit de mise en forme 44, lui-même relié à un moteur pas à pas 45 entraînant les aiguilles 46 de la montre, par l'intermédiaire d'un rouage.Conventionally, the part 40 comprises a quartz oscillator 41 supplying a signal whose frequency is approximately 32 kHz. This oscillator is connected to a divider 42 one of the outputs 43 of which is connected to part 50 of the circuit, the signal appearing at this output being constituted by a train of pulses whose pulses are spaced five minutes apart (0.003 Hz) , at least in the example described here. Conventionally, the divider is connected to a shaping circuit 44, itself connected to a stepping motor 45 driving the hands 46 of the watch, by means of a gear train.

Le contacteur 13 est raccordé à un circuit accumulateur 51 qui, dans cet exemple, est un simple compteur-décompteur, l'entrée de comptage 52 étant reliée au plot de contact 15 du contacteur, l'entrée de décomptage 53 à la sortie 43 du diviseur et la sortie de zéro 54 à un dispositif avertisseur 55 fournissant un signal audible, ou un autre signal analogue, lorsque le compteur-décompteur 51 parvient à la position 0. Ce compteur comporte également une entrée de remise à zéro 56 à laquelle est raccordé le plot de contact 33. Le dispositif d'avertissement 55 est pourvu d'un montage de temporisation pour assurer la production d'un signal d'alarme pendant un certain temps seulement après que le compteur-décompteur 51 a atteint sa position 0.Contactor 13 is connected to a battery circuit mulator 51 which, in this example, is a simple up-down counter, the up-counting input 52 being connected to the contact pad 15 of the contactor, the down-counting input 53 at the output 43 of the divider and the zero output 54 to a warning device 55 providing an audible signal, or another similar signal, when the up-down counter 51 reaches the position 0. This counter also includes a reset input 56 to which the contact pad 33 is connected. Warning 55 is provided with a timing arrangement to ensure the production of an alarm signal for a certain time only after the up-down counter 51 has reached its position 0.

Le fonctionnement du circuit de la figure 4 est le suivant. Lorsque l'utilisateur désire employer la minuterie pour fixer un intervalle de temps à mesurer, il place tout d'abord la tige 1 dans la position de travail tirée telle qu'illustrée aux figures 2 et 3. Il fait tourner la tige jusqu'à ce qu'apparaisse le chiffre 0 dans le guichet. A ce moment, comme on le voit en figure 3, le palpeur 26 est au fond de l'encoche 32 et la lame 14 entre en contact avec le plot 33, ce qui a pour effet de mettre à zéro le compteur-décompteur 51. L'utilisateur tourne alors la tige 1 jusqu'à ce que le chiffre correspondant à la durée souhaitée en minutes apparaisse derrière le guichet. Pendant cette opération le compteur-décompteur 51 se sera chargé au rythme du passage des dents 7 devant le palpeur 26. Le compteur-décompteur 51 a donc enregistré un certain nombre d'impulsions créés par les contacts répétés de la lame 14 sur le plot 15 et correspondant à autant de périodes de cinq minutes qui composent le laps de temps à mesurer. Une fois ce laps de temps réglé, la base de temps formée par l'oscillateur 41 et le diviseur 42 provoque le décomptage du contenu du compteur-décompteur 51 à raison d'une impulsion toutes les cinque minutes, la période à mesurer étant terminée lorsque le compteur-décompteur 51 parvient à 0. C'est à cet instant que l'alarme 55 agit pour prévenir l'utilisateur que le laps de temps s'est écoulé.The operation of the circuit of FIG. 4 is as follows. When the user wishes to use the timer to set a time interval to measure, he first places the rod 1 in the pulled working position as illustrated in Figures 2 and 3. He rotates the rod until what appears the number 0 in the window. At this time, as can be seen in FIG. 3, the probe 26 is at the bottom of the notch 32 and the blade 14 comes into contact with the pad 33, which has the effect of zeroing the up-down counter 51. The user then turns the rod 1 until the number corresponding to the desired duration in minutes appears behind the window. During this operation the up-down counter 51 will be charged at the rate of the passage of the teeth 7 in front of the probe 26. The down-up counter 51 has therefore recorded a certain number of pulses created by the repeated contacts of the blade 14 on the pad 15 and corresponding to as many five-minute periods which make up the period of time to be measured. Once this period of time has been set, the time base formed by the oscillator 41 and the divider 42 causes the content of the up-down counter 51 to be counted down at the rate of one pulse every five minutes, the period to be measured having ended when the up-down counter 51 reaches 0. It is at this instant that the alarm 55 acts to warn the user that the period of time has elapsed.

De la description ci-dessus on constate que si le verrou 16 n'existait pas, la lame pourrait venir en contact avec le plot d'incrémentation 15 lors de chocs appliqués à la pièce d'horlogerie. Les contacts intempestifs auraient pour effet de charger le compteur 51 d'impulsions non voulues, le laps de temps affiché ne correspondant alors plus à la période introduite dans le compteur 51.From the above description, it can be seen that if the lock 16 did not exist, the blade could come into contact with the incrementation pad 15 during impacts applied to the timepiece. The untimely contacts would have the effect of charging the counter 51 with unwanted pulses, the displayed time period no longer corresponding to the period entered in the counter 51.

La description ci-dessus a pris pour exemple un système de minuterie (ou timer) dans laquelle une commande manuelle agit de façon répétée sur un contact électrique. L'invention n'est pas limitée à l'exemple choisi mais englobe généralement tous les systèmes faisant intervenir un contacteur commandé à la main tels que ceux décrits dans les documents cités dans le préambule de la présente description, pourvu que ces systèmes fassent intervenir un verrou de sécurité empêchant des contacts intempestifs survenant à l'occasion de chocs appliqués à une pièce d'horlogerie.The above description has taken as an example a timer system (or timer) in which a manual control acts repeatedly on an electrical contact. The invention is not limited to the example chosen but generally encompasses all systems involving a hand-operated contactor such as those described in the documents cited in the preamble to this description, provided that these systems involve a safety lock preventing untimely contacts occurring during shocks applied to a timepiece.
