Abstract

The motor driving a minute-indicator in a down counting operation which must count a finite duration is stopped when the terminal post of its control circuit is connected to "earth" potential by an electric line. A seconds-hand, rotating in synchronism with a minute-indicator, effects several revolutions during the counting operation. It is rigid with an elastic arm which, at each revolution, slides on a part of the circuit, connecting the latter to earth. This produces however stopping of the motor only at the last revolution of the seconds-hand, when a contact switch mounted in series with the sliding switch is also closed under the action of a control pin acting on an elastic blade. This pin is carried by a manually operable rocking lever which is provided with a toothed sector meshing with a pinion rigid with the minute-indicator. When the rocking lever is operated, the motor is started due to the opening of the contact and, simultaneously, the minute-indicator is brought into its starting position for counting.

Description

La présente invention a pour objet un dispo­sitif d'arrêt dans une position déterminée d'un organe mobile entraîné par un moteur électrique et qui doit franchir au moins une fois sa position d'arrêt sans s'y arrêter.The present invention relates to a stop device in a determined position of a movable member driven by an electric motor and which must pass at least once its stop position without stopping there.

L'invention a également pour objet une pièce d'horlogerie à indicateur rotatif de comptage d'une durée finie, commandé par un moteur électrique, s'arrêtant en fin de comptage.The invention also relates to a timepiece with a rotary counting indicator of finite duration, controlled by an electric motor, stopping at the end of counting.

L'arrêt dans une position déterminée d'un organe mobile entraîné par un moteur électrique ne pose pas de problèmes dès lors que l'arrêt en question doit se produire à chaque passage de l'organe mobile dans ladite position. Il suffit en effet, dans ce cas, de munir l'or­gane mobile d'un moyen de commande d'un interrupteur électrique situé sur le circuit d'alimentation du moteur de telle sorte qu'au passage de l'organe mobile dans la position où doit se produire l'arrêt il ouvre ledit interrupteur, ce qui met le moteur hors service et pro­duit l'arrêt désiré.The stopping in a determined position of a movable member driven by an electric motor poses no problems as soon as the stopping in question must occur each time the movable member passes into said position. It suffices, in this case, to provide the movable member with a control means of an electric switch located on the motor supply circuit. so that when the movable member passes into the position where the stop must occur, it opens said switch, which puts the engine out of service and produces the desired stop.

Si, au contraire, l'organe mobile doit pou­voir franchir sans s'arrêter une ou plusieurs fois la position dans laquelle doit finalement se produire l'ar­rêt, c'est-à-dire sa position de fin de course, le pro­blème devient plus délicat.If, on the contrary, the movable member must be able to cross without stopping one or more times the position in which the stop must ultimately occur, that is to say its end-of-travel position, the problem becomes more delicate.

Le but de la présente invention est préci­sément de fournir une solution à ce problème.The object of the present invention is precisely to provide a solution to this problem.

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

L'arrêt d'un organe mobile dans une position déterminée qu'il doit pouvoir franchir préalablement une ou plusieurs fois sans s'arrêter est un problème qui se pose dans les compteurs de temps destinés à effectuer le comptage d'une durée finie, au sens mathématique du terme, qui comprennent deux indicateurs dont l'un indique le temps dans une unité et l'autre dans une autre unité constituant un sous-multiple de la première, et dans lesquels ce dernier indicateur, rotatif, doit pouvoir faire plus d'un tour pendant que le premier effectue sa course complète, d'un tour au maximum.The stopping of a movable member in a determined position which it must be able to cross beforehand one or more times without stopping is a problem which arises in the counters of time intended to carry out the counting of a finite duration, at the mathematical sense of the term, which include two indicators, one of which indicates time in one unit and the other in another unit constituting a submultiple of the first, and in which the latter, rotary indicator, must be able to make more than one lap while the first performs its complete stroke, by one maximum.

Le but de la présente invention est de four­nir une solution à ce problème.The object of the present invention is to provide a solution to this problem.

La montre-bracelet de sport représentée à la fig. 1, désignée d'une façon générale par 1, destinée à permettre aux plaisanciers de contrôler le temps qui reste à s'écouler avant que soit donné le départ d'une régate, comprend un mouvement électronique ordinaire, non représenté parce que connu en soi , à oscillateur à quartz, entraînant trois aiguilles ordinaires d'heures, de minu­tes et de secondes, désignées par 2, 3 et 4, respective­ment. Cette montre comprend encore un indicateur des quan­tièmes, lesquels apparaissent dans un guichet 5 ménagé dans le cadran, désigné par 6.The sports wristwatch shown in fig. 1, generally designated by 1, intended to allow boaters to control the time which remains to elapse before the start of a regatta, comprises an ordinary electronic movement, not shown because known per se , with quartz oscillator, driving three ordinary hands of hours, minutes and seconds, designated by 2, 3 and 4, respectively. This watch also includes an indicator for the dates, which appear in a window 5 made in the dial, designated by 6.

Outre le mouvement ordinaire d'entraînement des aiguilles indicatrices du temps courant, la montre représentée comprend un module autonome de compteur, superposé au mouvement ordinaire, côté cadran. Le bâti de ce module comprend une platine 7 percée d'une ou ver­ture 8 située en regard du guichet 5 du cadran 6. Cette platine 7 porte un moteur électrique, désigné d'une façon générale par 9, piloté par un oscillateur à quartz repré­senté schématiquement en 10, et dont le rotor porte un pignon 11 constituant le premier élément d'un train d'en­grenages comprenant des mobiles 12, 13, 14, 15 et 16; le pignon de ce dernier mobile, désigné par 17, engrène avec une roue 18 située au centre du mouvement. Cette roue 18 porte un indicateur de minutes constitué par un disque 19 présentant trois zones de couleurs différentes 19a, 19b et 19c (fig. 5), en forme de segments de couronne.In addition to the ordinary movement for driving the hands indicating the current time, the watch shown includes an autonomous counter module, superimposed on the ordinary movement, on the dial side. The frame of this module comprises a plate 7 pierced with an or groove 8 located opposite the window 5 of the dial 6. This plate 7 carries an electric motor, generally designated by 9, controlled by a quartz oscillator shown schematically at 10, and the rotor of which carries a pinion 11 constituting the first element of a gear train comprising mobiles 12, 13, 14, 15 and 16; the pinion of the latter mobile, designated by 17, meshes with a wheel 18 located in the center of the movement. This wheel 18 carries a minute indicator consisting of a disc 19 having three zones of different colors 19 a , 19 b and 19 c (fig. 5), in the form of crown segments.

Le circuit de pilotage du moteur 9, schéma­tiquement représenté en 20, comprend une borne 21 reliée à une piste conductrice 22a à 22e, isolée de la masse du mouvement, servant à commander le moteur 9. Le point ter­minal 22e de cette piste conductrice peut être mis à la masse grâce à des moyens qui seront indiqués plus loin; le circuit 20 est tel que, lorsque la borne 21 est à la masse, le moteur est arrêté.The motor control circuit 9, diagrammatically represented at 20, comprises a terminal 21 connected to a conductive track 22 a to 22 e , isolated from the mass of the movement, used to control the motor 9. The end point 22 e of this track conductive can be earthed by means which will be indicated later; circuit 20 is such that, when terminal 21 is grounded, the engine is stopped.

La montre comprend un poussoir 23 (fig. 1) permettant d'actionner manuellement une bascule 24 articulée en 25 sur la platine 7 et qui porte une che­ville 26 traversant une ouverture 27 de la platine ce qui limite les mouvements de la bascule. Cette der­nière est rappelée par un ressort 28.The watch includes a pusher 23 (fig. 1) allowing manual actuation of a lever 24 articulated at 25 on the plate 7 and which carries a pin 26 passing through an opening 27 of the plate which limits the movements of the lever. The latter is recalled by a spring 28.

La bascule 24 présente un nez 24a coopérant avec un nez 29a d'une bascule 29 pivotée en 30 sur la platine 7. La bascule 29 présente un secteur denté 29b, formant râteau, en prise avec un pignon 31 soli­daire de la roue 18 portant l'indicateur 19 des minu­tes. La bascule 29 porte en outre une butée réglable 32, montée sur excentrique, destinée à agir sur une lame élastique 33 pour l'amener en contact en 34 avec l'extrémité, désignée par 22d, de la piste conductrice 22c et la mettre ainsi à la masse.The rocker 24 has a nose 24 a cooperating with a nose 29 a of a rocker 29 pivoted at 30 on the plate 7. The rocker 29 has a toothed sector 29 b , forming a rake, engaged with a pinion 31 secured to the wheel 18 bearing the 19 minute indicator. The lever 29 further carries an adjustable stop 32, mounted on an eccentric, intended to act on an elastic blade 33 to bring it into contact at 34 with the end, designated by 22 d , of the conductive track 22 c and put it thus grounded.

Lorsqu'une pression est exercée sur le poussoir 23, comme l'indique la flèche 35 de la fig. 6, la bascule 24 amène la bascule 29 à tourner dans le sens de la flèche 36 ce qui, grâce à l'engrènement du râteau 29b avec le pignon 31 , fait tourner ce dernier et par conséquent l'indicateur 19 dans le sens de la flèche 37, c 'est-à-dire en sens rétrograde, jusqu'à buter contre une cheville d'arrêt réglable 38, montée sur excentrique, portée par la platine 7; simultanément, la cheville 32 quitte la lame 33, qui elle-même quitte la partie 22d de la piste conductrice, ce qui met le moteur 9 en mar­che dès lors que la borne 21 de son circuit de commande 20 n'est ainsi plus à la masse.When pressure is exerted on the pusher 23, as indicated by the arrow 35 in FIG. 6, the rocker 24 causes the rocker 29 to rotate in the direction of the arrow 36 which, thanks to the engagement of the rake 29 b with the pinion 31, rotates the latter and consequently the indicator 19 in the direction of the arrow 37, that is to say in the retrograde direction, until it stops against an adjustable stop pin 38, mounted on eccentric, carried by plate 7; simultaneously, the pin 32 leaves the blade 33, which itself leaves part 22 d of the conductive track, which starts the motor 9 as soon as the terminal 21 of its control circuit 20 is no longer at the mass.

Il est à remarquer que les deux éléments --pignon 17 et roue, désignée par 39-- du mobile 16 du train d'engrenages reliant le moteur 9 à l'indicateur 19 sont accouplés l'un à l'autre par un dispositif à friction comprenant une rondelle cambrée 40 (figs. 3 et 4), de ma­nière d'une part que le râteau 29b puisse être actionné sans que le train d'engrenages ne sollicite le moteur 9, et d'autre part que ce dernier puisse démarrer dès que le contact en 34 est ouvert alors même qu'une pression serait encore exercée sur le poussoir 23 et que, par conséquent, le pignon 31 serait alors bloqué par le râteau 29b.It should be noted that the two elements - pinion 17 and wheel, designated by 39 - of the mobile 16 of the gear train connecting the motor 9 to the indicator 19 are coupled to each other by a device to friction comprising a cambered washer 40 (figs. 3 and 4), so that on the one hand the rake 29 b can be actuated without the gear train urging the motor 9, and on the other hand that the latter can start as soon as the contact at 34 is open even though pressure would still be exerted on the pusher 23 and that, consequently, the pinion 31 would then be blocked by the rake 29 b .

Les trois zones de couleurs différentes 19a, 19b et 19c du disque 19 apparaissent successivement dans cinq guichets 41 (fig. 1) ménagés dans le cadran 6. L'utilisateur de la montre voit ainsi défiler les trois zones de couleurs différentes de l'indicateur 19 en re­gard de ces cinq guichets, ce qui lui donne une notion du temps qui reste à s'écouler jusqu'au moment où l'in­dicateur 19 aura regagné sa position initiale. Dans le cas particulier de la montre prévue pour être utilisée au dé­part de régates, la durée totale de déplacement de l'in­dicateur 19 sera de dix minutes.The three zones of different colors 19 a , 19 b and 19 c of the disc 19 appear successively in five apertures 41 (fig. 1) formed in the dial 6. The user of the watch thus sees the three zones of different colors of the indicator 19 next to these five windows, which gives it a notion of the time that remains to elapse until the indicator 19 has returned to its initial position. In the particular case of the watch intended to be used at the start of regattas, the total duration of movement of the indicator 19 will be ten minutes.

Afin que les indications fournies à l'utilisa­teur de la présente montre soient plus fines, la montre comprend une aiguille de secondes 42 montée sur l'arbre, désigné par 43 (fig. 4), du mobile 15 du train d'engrenages reliant le moteur 9 à l'indicateur 19. Cette aiguille de secondes fait un tour par minute, de sorte qu'elle est appelée à faire dix tours au cours des dix minutes de la course du disque 19; elle tourne en regard d'un tour de secondes 44 que présente le cadran 6 de la montre (fig. 1).So that the indications provided to the user of this watch are more precise, the watch includes a second hand 42 mounted on the shaft, designated by 43 (fig. 4), of the mobile 15 of the gear train connecting the motor 9 to the indicator 19. This second hand makes one revolution per minute, so that it is called upon to make ten revolutions during the ten minutes of the stroke of the disc 19; it rotates opposite a revolution of seconds 44 presented by the dial 6 of the watch (fig. 1).

Il est à remarquer que le disque indica­teur 19, qui n'effectue que des mouvements rotatifs oscillants, est percé d'une ouverture 45 en arc de cer­cle (fig. 5) livrant passage à l'arbre 43 de l'aiguille de secondes 42.It should be noted that the indicator disc 19, which performs only oscillating rotary movements, is pierced with an opening 45 in an arc of a circle (FIG. 5) delivering passage to the shaft 43 of the seconds hand 42 .

L'arbre 43 portant l'aiguille de secondes 42 porte, chassé sur lui, un coeur de remise à zéro 46 (fig. 4) sur lequel est fixée une lame élastique conduc­trice 47 laquelle est ainsi à la masse du mouvement, en­trant en contact, une fois par tour, avec la borne 22e terminant la piste conductrice 22a à 22c aboutissant à la borne 21 du circuit 20 de commande du moteur 9. Une fois par tour de l'aiguille 42, le bras 47 entre en contact avec la borne 22e et met ainsi la borne 21 à la masse, moyennant que le contact 34, monté en série avec le con­tact 47-22e soit fermé. Cependant, étant donné que, jusqu'au dernier tour de l'aiguille 42 ce contact 34 qu'actionne la cheville 32 de la bascule 29, est ouvert, cette mise à la masse de la borne 21 ne se produit pas, de sorte que le moteur 9 continue de tourner. Ce n'est qu'à la fin du dernier tour de l'aiguille 42 que, au mo­ment où celle-ci se trouve en regard du chiffre 60 du tour de secondes 44 et où le bras 47 entre en contact avec la borne 22e, si­ multanément la cheville 32 ferme l'interrupteur 34. La borne 21 du circuit 20 est alors mise à la masse et le moteur s'arrête, l'indicateur de minutes 19 étant alors à fin de course et l'aiguille de secondes 42 en regard du chiffre 60 du tour de secondes 44.The shaft 43 carrying the second hand 42 carries, driven on it, a reset heart 46 (fig. 4) on which is fixed an elastic conductive blade 47 which is thus to the mass of the movement, coming into contact , once per revolution, with terminal 22 e ending the conductive track 22 a to 22 c ending at terminal 21 of the circuit 20 for controlling the motor 9. Once per revolution of the needle 42, the arm 47 comes into contact with terminal 22 e and thus puts terminal 21 to earth, provided that contact 34, mounted in series with contact 47-22 e is closed. However, since, until the last turn of the needle 42, this contact 34 which the pin 32 of the rocker 29 actuates, is open, this grounding of the terminal 21 does not occur, so that the motor 9 continues to run. It is only at the end of the last turn of the needle 42 that, when the latter is opposite the number 60 of the turn of seconds 44 and when the arm 47 comes into contact with the terminal 22 e , if simultaneously the pin 32 closes the switch 34. The terminal 21 of the circuit 20 is then grounded and the motor stops, the minute indicator 19 then being at the end of its travel and the seconds hand 42 opposite of the digit 60 of the turn of seconds 44.

Etant donné que le poussoir 23 peut être actionné alors même que le compte à rebours s'effectue, c'est-à-dire alors même que le moteur 9 est en marche, et que l'aiguille 42 occupe une position quelconque en regard du tour de secondes 44 (fig. 7), il a été prévu qu'un marteau 48 assure la remise à zéro de cette aiguille. Ce marteau 48, articulé en 49 sur la platine 7, présente un bras 48a dont l'extrémité est engagée entre les bran­ches 24b d'une partie en forme de fourchette que présente la bascule 24. L'actionnement de celle-ci au moyen du poussoir 23 fait tourner le marteau 48 dans le sens de la flèche 50 (fig. 6) ce qui amène le marteau à coopérer avec le coeur de remise à zéro 46, ramenant ainsi l'ai­guille 42 en regard du chiffre 60 du tour de secondes 44. Il résulte de cette disposition que même si le mécanisme de commande est actionné manuellement en cours de compta­ge, l'aiguille 42 occupe toujours sa position initiale correcte au moment du début d'un nouveau comptage, lors­que la pression sur le poussoir 23 est relâchée.Since the pusher 23 can be actuated even when the countdown is in progress, that is to say even when the motor 9 is running, and the needle 42 occupies any position opposite the turn of seconds 44 (fig. 7), a hammer 48 has been provided for resetting this needle to zero. This hammer 48, articulated at 49 on the plate 7, has an arm 48 a , the end of which is engaged between the branches 24 b of a fork-shaped part which presents the rocker 24. The actuation of the latter at means of the pusher 23 rotates the hammer 48 in the direction of arrow 50 (fig. 6) which causes the hammer to cooperate with the reset core 46, thus bringing the needle 42 opposite the number 60 of the turn seconds 44. It follows from this arrangement that even if the control mechanism is actuated manually during counting, the needle 42 still occupies its correct initial position at the start of a new count, when the pressure on the pusher 23 is released.

Il est à remarquer que la liaison entre l'arbre 43 portant l'aiguille 42 et la roue, désignée par 51 (fig. 4), du mobile 15 est à friction, étant as­surée par une rondelle cambrée 52, de sorte que la remise à zéro de l'aiguille 42 s'effectue sans solliciter le train d'engrenages reliant le moteur 9 à l'indicateur 19.It should be noted that the connection between the shaft 43 carrying the needle 42 and the wheel, designated by 51 (fig. 4), of the mobile 15 is friction, being provided by a cambered washer 52, so that the delivery at zero of the needle 42 is carried out without stressing the gear train connecting the motor 9 to the indicator 19.

La pièce décrite et représentée, conçue spécifiquement en vue des départs de régates, n'est qu'un exemple d'application de l'invention, celle-ci pouvant s'appliquer à d'autres compteurs, de 45′ pour le foot­ball, par exemple, ou de plus longue durée encore, pour la plongée sous-marine notamment.The part described and shown, designed specifically for starting regattas, is only an example of application of the invention, which can be applied to other counters, 45 ′ for football, for example, or even longer, for scuba diving in particular.

L'organe indiquant un sous-multiple de l'indicateur principal , ici l'aiguille 42, pourra ne pas être un indicateur de secondes mais indiquer des fractions de seconde ou toute autre unité de temps.The member indicating a sub-multiple of the main indicator, here the needle 42, may not be a seconds indicator but indicate fractions of a second or any other unit of time.
