Abstract

The present invention concerns a timepiece having an alarm activating mechanism that serves for effecting the closure of an electrical contact (5a, 9) at a time which is adjustable in advance. The mechanism is arranged in the form of a module (100) which comprises a mechanically unitary assembly formed of two coaxial wheels (6, 8), one of which carries a contact element (9). This unitary assembly is mounted on the framework of the movement so that its angular position is manually adjustable about an axis, and it carries a wheel (5) which is in mesh with the hour wheel (3) and has an embossment (5a) which can enter into contact with the contact element (9). The invention is applicable more particularly to alarm watches.

Description

La présente invention a pour objet une pièce d'horlogerie selon le préambule de la revendication 1.The subject of the present invention is a timepiece according to the preamble of claim 1.

Le brevet US-A-3580504 décrit une pièce d'horlogerie dans laquelle un bras portant un aimant permanent est normalement entraîné en rotation par un disque gradué d'affichage de l'heure entraîné lui-même par un mouvement d'horlogerie. Dans son mouvement de rotation, l'aimant passe à proximité de deux éléments de contact en matériau magnétique doux, qui sont appliqués l'un contre l'autre par le champ magnétique de cet aimant. L'heure de déclenchement est donnée par la position du bras sur le disque, et elle peut être modifiée en déplaçant ce bras par rapport à ce disque.Patent US-A-3580504 describes a timepiece in which an arm carrying a permanent magnet is normally driven in rotation by a graduated time display disc itself driven by a clockwork movement. In its rotational movement, the magnet passes near two contact elements made of soft magnetic material, which are applied against each other by the magnetic field of this magnet. The trigger time is given by the position of the arm on the disc, and it can be modified by moving this arm relative to this disc.

Une telle disposition présente l'inconvénient que le bras portant l'aimant doit être fixé au disque à la fois de manière suffisamment rigide pour être entraîné en rotation par le disque et de manière suffisamment libre pour pouvoir tourner par rapport à ce disque, ce qui n'est pas très facile à réaliser. En outre, le déplacement du bras par rapport au disque pour modifier l'heure de déclenchement risque d'entraîner le disque, ce qui provoquerait une erreur dans l'heure affichée par celui-ci. Enfin, si l'heure courante est affichée par des aiguilles se déplaçant devant un cadran fixe, il n'est pas possible d'indiquer l'heure de déclenchement par rapport à ces aiguilles. Cette indication doit se faire par rapport à ce cadran fixe.Such an arrangement has the disadvantage that the arm carrying the magnet must be fixed to the disc both sufficiently rigidly to be driven in rotation by the disc and sufficiently free to be able to rotate relative to this disc, which is not very easy to achieve. In addition, moving the arm relative to the disc to change the trigger time may cause the disc, which would cause an error in the time displayed by it. Finally, if the current time is displayed by hands moving in front of a fixed dial, it is not possible to indicate the trigger time in relation to these hands. This indication must be made in relation to this fixed dial.

Le brevet suisse CH-A-526 154 décrit une montre-réveil ayant un mécanisme de déclenchement comportant une roue en matière isolante dont la position angulaire peut être réglée, et un bras métallique réalisé en une pièce avec le canon de la roue des heures. Un ressort sollicite la roue isolante contre une saillie se trouvant à l'extrémité dudit bras métallique. Le déclenchement du réveil se produit par l'entrée en contact de l'élément de contact que constitue ladite saillie avec un second élément de contact porté par la roue isolante.Swiss patent CH-A-526,154 describes an alarm watch having a trigger mechanism comprising a wheel of insulating material whose angular position can be adjusted, and a metal arm produced in one piece with the barrel of the hour wheel. A spring biases the insulating wheel against a projection located at the end of said metal arm. The triggering of the alarm occurs by the contacting of the contact element which constitutes said projection with a second contact element carried by the insulating wheel.

Un des inconvénients de ce mécanisme connu réside dans le fait que le bras métallique est soumis au cours de sa rotation, du fait de l'action du ressort de rappel, à une friction importante consommatrice d'énergie. Or, dans le cas des montres électroniques, où la source d'énergie est constituée par une pile électrique, de durée limitée, toute cause de surcroît de consommation doit évidemment être évitée.One of the drawbacks of this known mechanism lies in the fact that the metal arm is subjected during its rotation, due to the action of the return spring, to a significant friction consuming energy. However, in the case of electronic watches, where the energy source consists of an electric battery, of limited duration, any cause of additional consumption must obviously be avoided.

Le but de la présente invention est de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.

Ce but est atteint par les moyens revendiqués dans la revendication 1.This object is achieved by the means claimed in claim 1.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.

  • La figure 2 est une vue de détail en plan, à échelle agrandie, à partir du plan II-II de la figure 1, et
  • La figure 3 est une coupe verticale, suivant la ligne III-III de la figure 2.
The drawing represents, by way of example, an embodiment of the subject of the invention.
  • Figure 1 is an axial section of a part of an electronic alarm watch in which only the elements necessary for understanding the invention have been shown.
  • FIG. 2 is a detailed plan view, on an enlarged scale, from plane II-II of FIG. 1, and
  • Figure 3 is a vertical section along line III-III of Figure 2.

La montre représentée est du type électromécanique, les indicateurs du temps étant constitués par des aiguilles ordinaires d'heures 1 et de minutes 2, portées, la première, par le canon 3a de la roue à canon des heures, désignée par 3 et, la seconde par la chaussée, désignée par 4. Le mécanisme moteur, électrique, n'a pas été représenté, étant connu en soi. Il pourra être constitué par un moteur pas à pas piloté par un résonateur à quartz par l'intermédiaire d'une chaîne de division adéquate. L'énergie sera fournie par une pile électrique.The watch shown is of the electromechanical type, the time indicators being constituted by ordinary hour 1 and minute 2 hands, carried, first, by the barrel 3a of the hour barrel wheel, designated by 3 and, the second by the roadway, designated by 4. The motor, electric mechanism has not been shown, being known per se. It may be constituted by a stepping motor controlled by a quartz resonator via an adequate division chain. Energy will be supplied by an electric battery.

La roue à canon des heures 3 est en prise avec une roue de réveil 5, en acier, interposée, avec jeu suivant l'axe de rotation, entre une roue dentée 6, en matière électriquement isolante, montée rotativement dans la platine du mouvement, désignée par 7, et une roue 8, coaxiale à ladite roue isolante 6. Selon l'exemple représenté sur la figure 1, le rapport d'engrenage entre la roue à canon des heures 3 et la roue de réveil 5 est de 1 : 1 ; cependant, ce rapport peut avantageusement être de 1 : 2 afin que la roue de réveil fasse un tour par vingt quatre heures dans le cas d'une montre douze heures, dont la roue des heures fait deux tours par jour.The hour-barrel wheel 3 is engaged with a wake-up wheel 5, made of steel, interposed, with play along the axis of rotation, between a toothed wheel 6, of electrically insulating material, rotatably mounted in the movement plate, denoted by 7, and a wheel 8, coaxial with said insulating wheel 6. According to the example shown in FIG. 1, the gear ratio between the hour barrel wheel 3 and the alarm wheel 5 is 1: 1 ; however, this ratio can advantageously be 1: 2 so that the alarm wheel makes one revolution per twenty-four hours in the case of a twelve-hour watch, whose hour wheel makes two revolutions per day.

La roue 5 est mise à la masse notamment par l'intermédiaire de la roue 3 avec laquelle elle demeure en contact.The wheel 5 is earthed in particular by means of the wheel 3 with which it remains in contact.

La roue isolante 6 porte un aimant permanent électriquement conducteur 9, en forme de barreau, dont l'axe est parallèle à celui de ladite roue 6, et dont la distance au centre correspond à la distance au centre d'un bossage 5a, dirigé vers la roue isolante 6, que présente la roue 5. Cette dernière est engagée librement sur un canon 8a que présente la roue 8, canon traversé par un tourillon 6a de la roue 6. Cette dernière présente en outre un ergot 6b engagé dans une encoche du canon 8a de manière que les roues 6 et 8 soient solidaires angulairement. Elles sont maintenues assemblées par un rivetage 6c de l'extrémité du tourillon 6a.The insulating wheel 6 carries an electrically conductive permanent magnet 9, in the form of a bar, the axis of which is parallel to that of said wheel 6, and the distance from the center of which corresponds to the distance from the center of a boss 5a, directed towards the insulating wheel 6, which has the wheel 5. The latter is freely engaged on a barrel 8a which has the wheel 8, a barrel crossed by a pin 6a of the wheel 6. The latter also has a lug 6b engaged in a notch in the barrel 8a so that the wheels 6 and 8 are angularly integral. They are held together by riveting 6c from the end of the pin 6a.

La roue 6 porte, sur sa face opposée à celle tournée vers la roue 5, une rondelle métallique mince 10, en forme de couronne qui est fixée à ladite roue 6 au moyen de deux tétons 6d diamétralement opposés (fig. 2 et 3). Cette couronne 10 présente un bras radial 10a, dirigé vers l'intérieur. Ce bras 10a prend appui élastiquement sur l'extrémité d'une cheville 11, qui est coaxiale à la roue 6, et qui est portée par un substrat de circuit imprimé 12 de la montre. Cette cheville 11 est en contact électrique avec une des pistes conductrices, désignée par 13, dudit substrat de circuit 12. Le bras élastique 10a de la couronne 10, formant ressort, sollicite l'ensemble formé par la roue 6 et la roue 8 contre un pont 14 du bâti du mouvement de la montre. La roue 8 est garnie d'une couronne 15 de matière plastique antifriction par l'intermédiaire de laquelle elle prend appui sur le pont 14. Ce dernier subit de ce fait une légère déformation élastique, il constitue donc un ressort sollicitant l'ensemble mécaniquement unitaire formé par les roues 6 et 8 contre la platine 7.The wheel 6 carries, on its face opposite to that facing the wheel 5, a thin metal washer 10, in the form of a crown which is fixed to said wheel 6 by means of two diametrically opposed studs 6d (FIGS. 2 and 3). This ring 10 has a radial arm 10a, directed inward. This arm 10a rests elastically on the end of a pin 11, which is coaxial with the wheel 6, and which is carried by a printed circuit substrate 12 of the watch. This pin 11 is in electrical contact with one of the conductive tracks, designated by 13, of said circuit substrate 12. The elastic arm 10a of the crown 10, forming a spring, urges the assembly formed by the wheel 6 and the wheel 8 against a bridge 14 of the movement frame of the watch. The wheel 8 is furnished with a crown 15 of anti-friction plastic material by means of which it bears on the bridge 14. The latter therefore undergoes a slight elastic deformation, it therefore constitutes a spring urging the unit mechanically unitary formed by the wheels 6 and 8 against the plate 7.

La roue 6 est en prise avec un pignon de commande 16, actionnable manuellement à l'aide d'un mécanisme de commande 100 connu en soi, qui permet de modifier manuellement sa position angulaire. Quant à la roue 8, solidaire de la roue 6, elle est en prise avec une roue à canon supplémentaire 17. Cette dernière est engagée sur le canon 3a de la roue à canon 3, et elle comporte un canon 17a sur lequel est montée une aiguille 18 dite de réveil.The wheel 6 is engaged with a control pinion 16, which can be actuated manually using a control mechanism 100 known per se, which makes it possible to manually modify its angular position. As for the wheel 8, integral with the wheel 6, it is engaged with an additional barrel wheel 17. The latter is engaged on the barrel 3a of the barrel wheel 3, and it comprises a barrel 17a on which is mounted a so-called wake-up needle 18.

La roue isolante 6 comporte, sur sa face tournée vers la roue de réveil 5, une nervure annulaire 6e coaxiale à ladite roue 6, et dont la distance au centre est supérieure à celle de l'aimant 9. Un dégagement annulaire 19 est ménagé dans ladite face de la roue 6 du côté intérieur à la nervure 6e, et il est convenablement dimensionné de façon que le bossage 5a de la roue 5 n'entre pas en contact avec la roue 6, pour toute les positions angulaires relatives des roues 5 et 6 pour lesquelles le bossage 5a n'est pas situé en regard de l'aimant 9. Ce dégagement se raccorde par deux plans inclinés avec la face plane d'extrémité 9a que présente l'aimant 9 du côté dirigé vers la roue 5. Cette face d'extrémité 9a est en retrait par rapport au bord libre de la nervure 6e, afin que la roue 5 n'entre pas en contact avec l'aimant 9 lorsque ce dernier n'est pas en face du bossage 5a. Cependant, le retrait de la face d'extrémité 9a par rapport au bord libre de la nervure 6e est suffisamment faible pour que le bossage 5a entre en contact avec ladite face 9a lorsque ces deux éléments 5a, 9a sont en face l'un de l'autre.The insulating wheel 6 has, on its face facing the alarm wheel 5, an annular rib 6th coaxial with said wheel 6, and the distance from the center of which is greater than that of the magnet 9. An annular clearance 19 is provided in said face of the wheel 6 on the inside of the rib 6e, and it is suitably dimensioned so that the boss 5a of the wheel 5 does not come into contact with the wheel 6, for all the relative angular positions of the wheels 5 and 6 for which the boss 5a is not located opposite the magnet 9. This clearance is connected by two inclined planes with the flat end face 9a which the magnet 9 presents on the side directed towards the wheel 5. This end face 9a is set back relative to the free edge of the rib 6e, so that the wheel 5 does not come into contact with the magnet 9 when the latter is not opposite the boss 5a. However, the shrinkage of the end face 9a relative to the free edge of the rib 6e is low enough for the boss 5a to come into contact with said face 9a when these two elements 5a, 9a are opposite one of the 'other.

Le fonctionnement de la montre décrite et représentée est le suivant :

  • L'heure à laquelle le réveil doit se déclencher est déterminée par l'usager qui fait tourner la roue 16, ajustant ainsi la position angulaire de la roue isolante 6. Cette position angulaire, et par conséquent l'heure du déclenchement, peut être contrôlée à l'aide de l'aiguille 18 qui, entraînée par la roue 8, se déplace en regard du tour d'heures du cadran, non représenté, de la montre.
The operation of the watch described and shown is as follows:
  • The time at which the alarm must go off is determined by the user who turns the wheel 16, thus adjusting the angular position of the insulating wheel 6. This angular position, and therefore the time of triggering, can be controlled using the hand 18 which, driven by the wheel 8, moves opposite the hour turn of the dial, not shown, of the watch.

Lors de la rotation de la roue de réveil 5, entraînée en permanence par la roue à canon des heures 3, le bosssge 5a se trouve normalement en regard du dégagement annulaire 19.During the rotation of the wake-up wheel 5, permanently driven by the hour wheel barrel 3, the bosssge 5a is normally located opposite the annular clearance 19.

Une fois par tour de la roue 5, le bossage 5a de celle-ci vient se présenter en regard de l'aimant permanent 9 qui l'attire, produisant ainsi un léger déplacement axial de la roue 5, accompagné d'un léger basculement et d'un léger déplacement angulaire dans les limites autorisées par le jeu d'engrenages entre celle-ci et la roue à canon des heures 3. Le contact entre le bossage 5a et l'aimant 9 met ce dernier à la masse, puisque la roue 5 est elle-même à la masse, ce qui, par l'intermédiaire de la couronne 10 et de la cheville 11, met à la masse la piste conductrice 13. Un circuit électrique est ainsi fermé qui commande la mise en marche de la sonnerie du réveil.Once per revolution of the wheel 5, the boss 5a of the latter comes to face the permanent magnet 9 which attracts it, thus producing a slight axial displacement of the wheel 5, accompanied by a slight tilting and a slight angular displacement within the limits authorized by the set of gears between the latter and the hour wheel 3. The contact between the boss 5a and the magnet 9 puts the latter to ground, since the wheel 5 is itself grounded, which, by means of the crown 10 and the pin 11, earths the conductive track 13. An electrical circuit is thus closed which controls the activation of the bell of waking up.

Grâce à cette disposition, le mécanisme de déclenchement du réveil ne constitue aucune surcharge pour le mouvement, ne consommant pratiquement aucune énergie. De plus, le contact se ferme de façon instantanée, assurant un démarrage franc du mécanisme de sonnerie. En outre, ce mécanisme ne subit pratiquement aucune usure.Thanks to this arrangement, the alarm trigger mechanism does not constitute any overload for the movement, consuming almost no energy. In addition, the contact closes instantly, ensuring a frank start of the striking mechanism. In addition, this mechanism undergoes practically no wear.
