  • the setting of the wake-up time is done in one direction, so that the wheels 4 and 7 rotate counterclockwise A as figure 1 , while the time setting control tilts the trigger 30 counterclockwise and thus releases the rake 32 of the toothing 5 to allow this rotation of the wheel 4.

Description

Arrière-plan de l'inventionBackground of the invention

La présente invention concerne un mécanisme de commande de réveil comportant un organe de déclenchement de sonnerie, une came rotative des heures ayant un décrochement radial, un suiveur de came s'appuyant sensiblement radialement contre la came des heures et capable d'actionner le déclencheur de sonnerie par son mouvement, et des moyens manuels de réglage de l'heure de réveil, agencés pour ajuster un positionnement angulaire relatif entre la came des heures et le suiveur de came.The present invention relates to an alarm control mechanism comprising a bell triggering device, a rotary hour cam having a radial recess, a cam follower substantially radially against the hour cam and capable of actuating the trigger of ring by its movement, and manual means for setting the alarm time, arranged to adjust a relative angular positioning between the hour cam and the cam follower.

Par le terme de « réveil », on entend désigner non seulement le système de sonnerie dans les pièces d'horlogerie appelées réveils, mais tout dispositif produisant un signal (appelé aussi alarme) à une heure présélectionnée dans une pièce d'horlogerie quelconque, notamment une montre.By the term "awakening" is meant not only the ringing system in timepieces called alarm clocks, but any device producing a signal (also called alarm) at a time preselected in any timepiece, including a watch.

Un exemple de mécanisme de ce genre est illustré par le brevet CH 341771 et comporte un levier basculant dont un bras est poussé par un ressort pour suivre le pourtour d'une came rotative en forme de spirale ayant un décrochement radial brusque. La came est montée à friction, afin que sa position angulaire soit ajustable pour le réglage de l'heure de réveil, sur une roue entraînée par le mouvement d'horlogerie et faisant un tour en 24 heures. L'autre bras du levier coopère avec les moyens déclenchant la sonnerie et avec un poussoir pour l'arrêt de la sonnerie. Un tel levier occupe passablement d'espace à côté de la came, ce qui peut être un inconvénient, notamment dans une montre à grande complication.An example of such a mechanism is illustrated by the patent CH 341771 and comprises a rocking lever whose arm is urged by a spring to follow the periphery of a rotating spiral cam having a sudden radial recess. The cam is friction mounted, so that its angular position is adjustable for setting the waking time, on a wheel driven by the watch movement and making a turn in 24 hours. The other arm of the lever cooperates with the means triggering the ring and with a pusher for stopping the ring. Such a lever occupies a lot of space next to the cam, which can be a disadvantage, especially in a watch with great complication.

Les mécanismes habituels de commande de réveil, par exemple comme celui décrit dans le document de brevet GB 1397982 , comportent deux roues coaxiales ayant entre elles un système de came frontal, de sorte qu'à l'heure de réveil l'une des roues se déplace axialement vers l'autre et permet ainsi le déclenchement de la sonnerie. Les principaux inconvénients de ces mécanismes sont leur relative imprécision de l'instant du déclenchement et les problèmes de réarmement du système pour qu'il sonne de nouveau 24 heures plus tard sans devoir être réarmé spécialement par une action de l'utilisateur.The usual waking control mechanisms, for example as described in the patent document GB 1397982 , comprise two coaxial wheels having between them a front cam system, so that at the waking time one of the wheels moves axially towards the other and thus allows the triggering of the ring. The main drawbacks of these mechanisms are their relative inaccuracy of the instant of the trigger and the problems of rearming the system so that it rings again 24 hours later without having to be rearmed by a special action of the user.

Résumé de l'inventionSummary of the invention

La présente invention vise à créer un mécanisme de commande de réveil permettant d'éviter dans une large mesure les inconvénients précités de l'art antérieur, notamment en limitant l'encombrement en largeur du mécanisme, par exemple pour pouvoir l'intégrer dans un mouvement de montre à grande complication. Un but particulier est de créer un type de mécanisme pouvant, au besoin, être complété par une came des minutes afin de déterminer avec plus de précision l'instant du déclenchement de la sonnerie. En outre, un mode de réalisation particulier de l'invention devrait permettre de faire sonner le réveil une seconde fois quelques minutes après l'heure de réveil.The present invention aims at creating a wake-up control mechanism which makes it possible to avoid to a large extent the above-mentioned drawbacks of the prior art, in particular by limiting the overall width of the mechanism, for example in order to be able to integrate it into a movement watch with great complication. A particular goal is to create a type of mechanism that can be supplemented, if necessary, by a minute cam to more accurately determine when the bell will sound. In addition, a particular embodiment of the invention should make it possible to sound the alarm a second time a few minutes after the waking time.

Selon un concept de base de l'invention, il est prévu un mécanisme tel que défini dans la revendication 1.According to a basic concept of the invention, there is provided a mechanism as defined in claim 1.

Ainsi, la chaîne cinématique allant de la came des heures de réveil à la roue de déclenchement est concentrée dans un groupe compact de roues coaxiales, qui peuvent être portées par un arbre commun et occupent un espace réduit en plan. Puisque le réglage de l'heure de réveil agit sur la roue de programmation et non sur la came des heures, il n'y a plus de transmission à friction entre le mouvement d'horlogerie et la came des heures, si bien que tout le mécanisme peut être à entraînement positif.Thus, the driveline from the waking hours cam to the trigger wheel is concentrated in a compact group of coaxial wheels, which can be carried by a common shaft and occupy a reduced planar space. Since the setting of the wake-up time acts on the programming wheel and not on the hour cam, there is no more frictional transmission between the watch movement and the hour cam, so that all mechanism can be positive drive.

De plus, selon un mode de réalisation perfectionné, ce groupe de roues coaxiales peut comporter également une came des minutes de réveil. Cette came est entraînée de façon à faire un tour par heure, et comporte au moins une encoche radiale. Le suiveur de came comporte un second doigt prévu pour s'appuyer contre la came des minutes. Ainsi, le moment du déclenchement de la sonnerie est déterminé par la conjonction des positions respectives de l'encoche de la came des minutes et de celle de la came des heures. Grâce à cette caractéristique, le moment du déclenchement de la sonnerie peut être déterminé avec plus de précision.In addition, according to an improved embodiment, this group of coaxial wheels may also include a cam of the waking minutes. This cam is driven to make one turn per hour, and has at least one radial notch. The cam follower has a second finger provided to press against the minute cam. Thus, the moment of the triggering of the ring is determined by the conjunction of the respective positions of the notch of the minute cam and that of the hour cam. With this feature, the time of the ringing can be determined more accurately.

D'autres particularités et avantages de la présente invention apparaîtront dans la description suivante d'un mode de réalisation préféré, en référence aux dessins annexés.Other features and advantages of the present invention will become apparent from the following description of a preferred embodiment, with reference to the accompanying drawings.

Description détaillée d'un mode de réalisationDetailed description of an embodiment

Le mécanisme de commande de réveil représenté dans les figures 1 et 2 comporte un groupe 1 de roues coaxiales comprenant, de haut en bas selon la figure 2 : une roue des heures 2, pourvue d'une came des heures 3 ; une roue de déclenchement 4 pourvue d'une denture extérieure circulaire 5 et d'un pignon 6 ; une roue de programmation 7 portant un levier suiveur de came 8 et une came am/pm 9 ; un disque de retenue appelé surprise 11 et pourvu d'un ressort 12 ; et enfin une roue des minutes 13 pourvue d'une came des minutes 14. Toutes les roues du groupe 1 sont traversées par un alésage central 16 pour être montées en libre rotation sur un arbre de façon à pouvoir tourner chacune autour d'un axe commun 17 qui est perpendiculaire à la platine (non représentée) du mouvement d'horlogerie. Les roues des heures 2 et des minutes 13 sont reliées par un engrenage ayant un rapport de transmission de 24/1 et comprenant le mobile de minuterie 20 de l'affichage analogique de l'heure courante de la montre. Ce mobile 20 comporte une roue 21 s'engrenant avec la roue 13 et entraînée comme d'habitude par le mouvement d'horlogerie, de telle sorte que la roue 13 fait un tour par heure. Le mobile 20 comporte en outre un pignon 22 relié par deux roues de renvoi 23 et 24 à la roue des heures 2 de façon que celle-ci fasse continuellement un tour en 24 heures. Ainsi, la position des cames 3 et 14 représente l'heure courante affichée par les aiguilles de la montre, avec une information supplémentaire (am/pm) puisque la came 2 détermine l'heure sur 24 heures au lieu de 12.The wake up control mechanism shown in the figures 1 and 2 comprises a group 1 of coaxial wheels comprising, from top to bottom according to the figure 2 : a wheel hours 2, provided with a cam hours 3; a trigger wheel 4 provided with a circular outer toothing 5 and a pinion 6; a programming wheel 7 carrying a cam follower lever 8 and a cam am / pm 9; a retaining disk called surprise 11 and provided with a spring 12; and finally a minute wheel 13 provided with a minute cam 14. All the wheels of the group 1 are traversed by a central bore 16 to be freely rotatably mounted on a shaft so as to be able to rotate each about a common axis 17 which is perpendicular to the plate (not shown) of the watch movement. The hours 2 and minute 13 wheels are connected by a gear having a transmission ratio of 24/1 and including the timer wheel 20 of the analog display of the current time of the watch. This mobile 20 comprises a wheel 21 meshing with the wheel 13 and driven as usual by the clockwork movement, so that the wheel 13 makes one turn per hour. The mobile 20 further comprises a pinion 22 connected by two return wheels 23 and 24 to the hour wheel 2 so that it makes a continuous turn in 24 hours. Thus, the position of the cams 3 and 14 represents the current time displayed by the hands of the watch, with additional information (am / pm) since the cam 2 determines the time over 24 hours instead of 12.

Dans la figure 1, les éléments du groupe 1 sont représentés en transparence. Dans cet exemple, les dentures extérieures des roues 4 et 7 ont pratiquement le même diamètre et se confondent donc dans la vue en plan. La denture de la roue de programmation 4 s'engrène sur un pignon non représenté, solidaire d'une roue 26 faisant partie des moyens manuels 25 de réglage de l'heure de réveil. Ces moyens sont classiques et n'ont pas besoin d'être décrits ici. On précisera seulement que dans le cas présent, la roue 26 fait partie d'un mobile de minuterie de l'affichage analogique de l'heure de réveil, comportant une aiguille des minutes, une aiguille des heures faisant un tour en 12 heures, et un indicateur am/pm commandé par un palpeur 27 qui s'appuie contre le pourtour de la came 9 fixée à la roue des heures 2.In the figure 1 , the elements of group 1 are represented in transparency. In this example, the outer teeth of the wheels 4 and 7 have substantially the same diameter and therefore merge in the plan view. The toothing of the programming wheel 4 meshes with a not shown pinion, integral with a wheel 26 forming part of the manual means 25 for setting the wake-up time. These means are conventional and do not need to be described here. It will be specified only that in the present case, wheel 26 is part of a timer mobile of the analog display of the waking hour, comprising a minute hand, an hour hand making a turn in 12 hours, and an am / pm indicator controlled by a probe 27 which bears against the periphery of the cam 9 fixed to the wheel of hours 2.

Un déclencheur 30 (en anglais : trigger) de sonnerie est formé par un levier porté par un pivot 31. Un râteau 32 situé à une extrémité du déclencheur 30 s'engrène sur la denture 5 de la roue de déclenchement 4. La partie du déclencheur 30 qui comporte le râteau 32 est légèrement flexible dans son plan, ce qui permet au râteau de fonctionner comme un cliquet sur la denture 5, comme on l'expliquera plus loin. Le déclencheur 30 est sollicité en rotation dans le sens horaire par un ressort de rappel (non représenté) relativement faible, juste suffisant pour maintenir le râteau 32 légèrement en butée contre la denture 5. En outre, lorsque la sonnerie est dans son état enclenché, la force d'un ressort d'armage R, agissant plus fort que le ressort de rappel, tend à faire pivoter le déclencheur 30 dans le sens horaire pour le maintenir appuyé fortement contre la denture 5 et donc tendre à faire tourner la roue de déclenchement 4 dans le sens antihoraire indiqué par la flèche A. L'autre extrémité du déclencheur 30 est pourvue d'organes spéciaux 34 pour commander la mise en marche de la sonnerie, lorsque le déclencheur pivote dans le sens horaire, et le retour en arrière du déclencheur lorsque la sonnerie s'arrête. Ces organes peuvent être de différents types connus et n'ont pas besoin d'être décrits en détails ici.A ringing trigger 30 is formed by a lever carried by a pivot 31. A rake 32 located at one end of the trigger 30 meshes with the toothing 5 of the trigger wheel 4. The trigger part 30 which includes the rake 32 is slightly flexible in its plane, which allows the rake to function as a ratchet on the toothing 5, as will be explained later. The trigger 30 is rotated in the clockwise direction by a return spring (not shown) relatively small, just enough to keep the rake 32 slightly abut against the toothing 5. In addition, when the ring is in its engaged state, the force of an armature spring R, acting stronger than the return spring, tends to rotate the trigger 30 clockwise to keep it pressed strongly against the toothing 5 and thus tend to rotate the trigger wheel 4 The counterclockwise end indicated by the arrow A. The other end of the trigger 30 is provided with special members 34 to control the start of the ring, when the trigger rotates clockwise, and the return back of the trigger when the buzzer stops. These organs can be of various known types and do not need to be described in detail here.

Dans les figures 3, 6a, 6b et 6c, on voit en détails le levier suiveur de came 8 monté sur la roue de programmation 7 au moyen d'un pivot 36 décentré sur la roue 7, le levier 8 ayant une saillie latérale pourvue d'une crémaillère 37 engrenée sur le pignon 6 de la roue de déclenchement 5, laquelle est enlevée dans ces figures afin de clarifier le dessin. Pour éviter qu'il soit flottant, le levier 8 est poussé légèrement vers l'intérieur par un ressort 38 dont l'extrémité arrière 39 est fixée sur la roue 7, de sorte que le levier 8 reste en appui contre la denture du pignon 6. Dans les vues en perspective des figures 4 et 5, on voit plus particulièrement comment le levier 8 coopère avec les cames 3 et 14 et la surprise 11. À son extrémité avant est fixée une goupille 40 de section triangulaire, qui s'étend parallèlement à l'axe 17 et forme un doigt supérieur 40a et un doigt inférieur 40b capables de s'appuyer sensiblement radialement contre les périphéries respectives des cames 3 et 14, ainsi que contre la surprise 11. Une ouverture 41 (voir figure 1) est ménagée dans la roue de déclenchement 4 pour laisser passer la goupille 40 avec un jeu suffisant pour ses mouvements par rapport à cette roue. De même, on voit dans la figure 3 qu'une ouverture 42 est ménagée dans la roue 7 pour permettre à la goupille 40 (qui est omise dans cette figure afin de clarifier le dessin) de traverser cette roue sans la toucher.In the figures 3 , 6a, 6b and 6c it is seen in detail the cam follower lever 8 mounted on the programming wheel 7 by means of a pivot 36 off-center on the wheel 7, the lever 8 having a lateral projection provided with a rack 37 meshing on the pinion 6 of the trigger wheel 5, which is removed in these figures to clarify the drawing. To prevent it being floating, the lever 8 is pushed slightly inwards by a spring 38 whose rear end 39 is fixed on the wheel 7, so that the lever 8 remains in abutment against the toothing of the pinion 6 In the perspective views of Figures 4 and 5 , we see more particularly how the lever 8 cooperates with the cams 3 and 14 and the surprise 11. At its front end is fixed a pin 40 of triangular section, which extends parallel to the axis 17 and forms an upper finger 40a and a lower finger 40b capable of to rest substantially radially against the respective peripheries of the cams 3 and 14, as well as against the surprise 11. An opening 41 (see FIG. figure 1 ) is formed in the trigger wheel 4 to let the pin 40 with sufficient clearance for its movements relative to this wheel. Similarly, we see in the figure 3 an opening 42 is formed in the wheel 7 to allow the pin 40 (which is omitted in this figure to clarify the drawing) to cross this wheel without touching it.

On se référera maintenant plus particulièrement aux figures 4 et 5. La périphérie de la came des heures 3 comprend une partie cylindrique 43 et une encoche radiale 44. La périphérie de la came des minutes 14 comprend aussi une partie cylindrique 46, de rayon légèrement inférieur à celui de la partie 43 de l'autre came, et deux encoches radiales 47 et 48 dont les décrochements radiaux d'entrée sont décalés mutuellement de 30 °, ce qui correspond à 5 minutes de rotation de la came 14. La périphérie de la surprise 11 comprend une partie cylindrique 50, de rayon légèrement inférieur à ceux des parties 43 et 46 des cames, et deux encoches radiales 51 et 52 décalées angulairement dans la même mesure que les encoches 47 et 48, mais un peu plus étroites que celles-ci en direction circonférentielle. Chaque encoche 51, 52 de la surprise est suivie d'une partie saillante respective 53, 54 dont la surface extérieure comprend un biseau d'entrée 55, 56 suivi d'une partie cylindrique 57, 58 de rayon légèrement plus grand que ceux des parties cylindriques 43 et 46 des cames. Une extrémité du ressort 12 intégré à la surprise 11 bute contre une cheville 59 fixée à la came des minutes 14 et tendant à maintenir la surprise sur cette came dans une position relative telle que les parties saillantes 53 et 54 de la surprise couvrent les encoches 47 et 48. Toutefois, quand la surprise est sollicitée dans le sens antihoraire, le ressort 12 a suffisamment de débattement radial pour permettre à la surprise 11 de pivoter sur la came 14 dans une mesure suffisante pour lui permettre de découvrir les encoches 47 et 48 et permettre ainsi à la goupille 40 d'entrer dans l'une d'elles.We will now refer more particularly to Figures 4 and 5 . The periphery of the hour cam 3 comprises a cylindrical portion 43 and a radial notch 44. The periphery of the minute cam 14 also comprises a cylindrical portion 46, with a radius slightly smaller than that of the portion 43 of the other cam, and two radial notches 47 and 48 whose radial input recesses are mutually offset by 30 °, which corresponds to 5 minutes of rotation of the cam 14. The periphery of the surprise 11 comprises a cylindrical portion 50, of slightly smaller radius those of the parts 43 and 46 of the cams, and two radial notches 51 and 52 angularly offset to the same extent as the notches 47 and 48, but a little narrower than these in the circumferential direction. Each notch 51, 52 of the surprise is followed by a respective projecting portion 53, 54 whose outer surface comprises an inlet bevel 55, 56 followed by a cylindrical portion 57, 58 of radius slightly larger than those of the parts cylindrical 43 and 46 of the cams. One end of the spring 12 integrated with the surprise 11 abuts an ankle 59 fixed to the minute cam 14 and tends to maintain the surprise on this cam in a relative position such that the protruding portions 53 and 54 of the surprise cover the notches 47 and 48. However, when the surprise is biased counterclockwise, the spring 12 has sufficient radial deflection to allow the surprise 11 to pivot on the cam 14 to a sufficient extent to allow it to discover the notches 47 and 48 and thus allow the pin 40 to enter one of them.

Le mécanisme fonctionne de la manière suivante. L'utilisateur règle l'heure de réveil (avec une résolution de l'ordre de la minute) en faisant tourner la roue 26 (voir figure 1) au moyen de la commande appropriée. Il positionne ainsi d'une part les aiguilles des heures et des minutes de l'affichage de l'heure de réveil, et d'autre part la roue de programmation 7 et la roue déclenchement 4 liée à la roue 7 au moyen de son pignon 6 et du levier suiveur de came 8. Le réglage de l'heure de réveil se fait dans une seule direction, pour que les roues 4 et 7 tournent dans le sens antihoraire A selon la figure 1, pendant que la commande de mise à l'heure fait basculer le déclencheur 30 dans le sens antihoraire et dégage ainsi le râteau 32 de la denture 5 pour permettre cette rotation de la roue 4. Grâce à la petite résistance opposée par le pignon 6, le levier 8 est alors soulevé dans la position représentée dans la figure 6b, où sa goupille 40 est maintenue éloignée des cames et de la surprise 11.The mechanism works as follows. The user sets the wakeup time (with a resolution of the order of a minute) by turning the wheel 26 (see figure 1 ) by means of the appropriate command. It thus positions on the one hand the hour and minute hands of the display of the alarm time, and on the other hand the programming wheel 7 and the trigger wheel 4 linked to the wheel 7 by means of its pinion 6 and the cam follower lever 8. The setting of the wake-up time is done in one direction, so that the wheels 4 and 7 rotate counterclockwise A as figure 1 , while the time setting control tilts the trigger 30 counterclockwise and thus releases the rake 32 of the toothing 5 to allow this rotation of the wheel 4. Due to the small resistance opposed by the pinion 6, the lever 8 is then raised in the position shown in the figure 6b where pin 40 is kept away from cams and surprise 11.

Lorsque la sonnerie du réveil n'est pas armée, il n'y a pas d'action du ressort d'armage R. Le déclencheur 30 et le levier suiveur de came 8 sont sollicités seulement par leurs faibles ressorts de rappel, si bien que la goupille 40 n'est poussée que faiblement contre les cames et la surprise, de sorte qu'elle ne peut pas pénétrer dans les encoches 47 et 48 couvertes par les parties saillantes 53 et 54 de la surprise, car le ressort 12 de la surprise offre une résistance suffisante pour l'empêcher de pivoter. La goupille 40 glisse sur la came des heures et passe sur les parties saillantes de la surprise en glissant sur leurs biseaux 55 et 56. Comme le levier 8 et sa goupille 40 bougent très peu sur la roue 7, la roue 4 et son pignon 6 restent pratiquement stationnaires et ne font donc pas bouger le déclencheur 30.When the alarm clock is not armed, there is no action of the winding spring R. The trigger 30 and the cam follower lever 8 are solicited only by their low return springs, so that the pin 40 is pushed only slightly against the cams and the surprise, so that it can not penetrate the notches 47 and 48 covered by the protruding portions 53 and 54 of the surprise, because the spring 12 of the surprise provides sufficient strength to prevent it from rotating. The pin 40 slides on the hour cam and passes on the protruding parts of the surprise by sliding on their bevels 55 and 56. As the lever 8 and pin 40 move very little on the wheel 7, the wheel 4 and its pinion 6 remain virtually stationary and therefore do not move the trigger 30.

Si la sonnerie du réveil est armée, cela veut dire que le ressort R agit sur le déclencheur 30 et la roue de déclenchement 4 dans le sens indiqué par les flèches R et A (figure 1). En référence aux figures 3 et 6a, le pignon 6 produit alors sur le levier 8 un couple tendant à appuyer radialement la goupille 40 avec une certaine force F contre les cames et la surprise. Avant l'heure de réveil, la goupille 40 glisse contre la partie cylindrique 43 de la came des heures 3 et ne peut donc pas tomber dans les encoches de la came des minutes lorsque celles-ci passent devant elle.If the alarm clock is armed, it means that the spring R acts on the trigger 30 and the trigger wheel 4 in the indicated direction by the arrows R and A ( figure 1 ). With reference to figures 3 and 6a the pinion 6 then produces on the lever 8 a torque tending to press the pin 40 radially with a certain force F against the cams and the surprise. Before the wakening time, the pin 40 slides against the cylindrical portion 43 of the hour cam 3 and can not fall into the notches of the minute cam when they pass in front of it.

Plusieurs minutes avant l'heure de réveil, le décrochement 44 de la came des heures passe devant la goupille 40. La goupille peut alors effectuer un petit déplacement radial pour aller s'appliquer en glissant contre la partie cylindrique 46 de la came des minutes 14, comme dans la situation illustrée par la figure 5. Elle est ensuite touchée par le biais 55 de la première partie saillante 53 de la surprise 11, couvrant la première encoche 47 de la came des minutes. La force F est suffisante pour que la goupille 40 fasse pivoter la surprise dans le sens antihoraire A en surmontant la résistance que le ressort 12 oppose à ce mouvement, jusqu'à ce que la goupille puisse entrer dans l'encoche 47 à l'instant précis choisi comme heure de réveil. Sous l'action du ressort R, le levier 8 effectue un basculement limité jusqu'à la position illustrée en figure 6c. Ce mouvement permet, via la crémaillère 37, un pivotement limité du pignon 6 et de la roue de déclenchement 4 dans le sens antihoraire A, ainsi que du déclencheur 30 dans le sens horaire dans une mesure suffisante pour enclencher la sonnerie du réveil. Ainsi, la roue de déclenchement 4 et son pignon 6 remplissent la fonction d'un renvoi, disposé entre le levier 8 et le déclencheur de sonnerie 30, pour transmettre le mouvement de basculement du premier au second et vice versa. Grâce à la forme circulaire de la denture 5 de la roue 4, cette liaison est disponible dans n'importe quelle position de la roue de programmation 7, c'est-à-dire pour n'importe quel réglage de l'heure de réveil.Several minutes before the wakeup time, the step 44 of the hour cam passes in front of the pin 40. The pin can then make a small radial displacement to apply sliding against the cylindrical portion 46 of the minute cam 14 as in the situation illustrated by the figure 5 . It is then touched through 55 of the first protruding portion 53 of the surprise 11, covering the first notch 47 of the minute cam. The force F is sufficient for the pin 40 to rotate the surprise counterclockwise A overcoming the resistance that the spring 12 opposes this movement, until the pin can enter the notch 47 at the moment accurate chosen as wake up time. Under the action of the spring R, the lever 8 makes a limited tilting up to the position illustrated in FIG. Figure 6c . This movement allows, via the rack 37, a limited pivoting of the pinion 6 and the trigger wheel 4 in the counterclockwise direction A, and the trigger 30 clockwise to a sufficient extent to trigger the alarm clock. Thus, the trigger wheel 4 and its pinion 6 perform the function of a return disposed between the lever 8 and the ringing trigger 30, to transmit the tilting movement from the first to the second and vice versa. Thanks to the circular shape of the toothing 5 of the wheel 4, this connection is available in any position of the programming wheel 7, that is to say for any setting of the waking time. .

Si l'utilisateur arrête alors la sonnerie, cela supprime l'action du ressort d'armage R et la force F du levier 8 sur la goupille 40. La goupille 40 est repoussée hors de l'encoche 47 par le flanc de celle-ci, laissant ainsi revenir la surprise pour recouvrir cette encoche pour que la goupille ne puisse pas y rentrer. Lorsque la seconde encoche 48 de la came des minutes arrive devant la goupille 40, le biseau 56 de la partie saillante 54 de la surprise 11 résiste suffisamment pour repousser la goupille et la laisser passer en glissant contre la surface 58 de la surprise. Ainsi, la goupille ne peut pas entrer dans la seconde encoche 48. Une fois que cette dernière et la partie saillante 54 ont passé, la goupille 40 peut retourner s'appuyer contre la came des heures 3, dont l'encoche 43 a fini de passer.If the user then stops the ringing, this eliminates the action of the winding spring R and the force F of the lever 8 on the pin 40. The pin 40 is pushed out of the notch 47 by the side thereof , leaving return the surprise to cover this notch so that the pin can not enter. When the second notch 48 of the minute cam arrives in front of the pin 40, the bevel 56 of the projecting portion 54 of the surprise 11 resists sufficiently to push the pin and let it slip against the surface 58 of the surprise. Thus, the pin can not enter the second notch 48. Once the latter and the protruding portion 54 have passed, the pin 40 can return to bear against the hour cam 3, the notch 43 has finished pass.

Si l'utilisateur n'a pas arrêté la sonnerie à l'heure de réveil, la sonnerie s'arrête d'elle-même après une durée prédéterminée grâce à un mécanisme adéquat, lequel agit aussi sur le râteau des organes 34 pour faire pivoter le déclencheur 30 dans le sens antihoraire, à l'encontre de la force du ressort R. La goupille 40 peut donc ressortir de l'encoche 47 comme indiqué dans le paragraphe précédent. Ensuite, le mécanisme précité cesse de repousser le déclencheur 30, le ressort R a de nouveau pour effet de presser la goupille contre la surprise 11, puis sur la came des minutes 14. La surface cylindrique de cette came glisse alors contre la goupille dans la situation illustrée par la figure 4, jusqu'à ce que la seconde partie saillante 54 de la surprise bute contre la goupille et soit repoussée en arrière par celle-ci en faisant pivoter la surprise comme à l'heure de réveil. Cinq minutes après l'heure de réveil, la seconde encoche 48 de la came des minutes a suffisamment avancé pour que la goupille 40 puisse y entrer et laisse ainsi pivoter les éléments 8, 6, 4 et 30 pour déclencher la sonnerie. La suite se déroule de la même manière qu'à l'heure du réveil. Si l'on voulait, la came des minutes pourrait avoir une troisième encoche radiale pour déclencher la sonnerie une troisième fois.If the user has not stopped the ring at the waking time, the ringing stops itself after a predetermined time thanks to a suitable mechanism, which also acts on the rake of the organs 34 to rotate the trigger 30 in the counterclockwise direction, against the force of the spring R. The pin 40 can therefore emerge from the notch 47 as indicated in the previous paragraph. Then, the aforementioned mechanism stops pushing the trigger 30, the spring R again has the effect of pressing the pin against the surprise 11, and then on the minute cam 14. The cylindrical surface of this cam then slides against the pin in the situation illustrated by the figure 4 , until the second projecting portion 54 of the surprise abuts against the pin and is pushed back by it by turning the surprise as the waking time. Five minutes after the wakeup time, the second notch 48 of the minute cam has advanced enough that the pin 40 can enter and thus allows the elements 8, 6, 4 and 30 to rotate to trigger the ring. The rest happens in the same way as at waking time. If one wanted, the minute cam could have a third radial notch to sound the ring a third time.

La construction décrite ci-dessus peut évidemment faire l'objet de modifications sans perdre la caractéristique fonctionnelle essentielle consistant à faire pivoter la roue de déclenchement par rapport à la roue de programmation pour déclencher la sonnerie. Par exemple, le levier 8 pourrait éventuellement être remplacé par un élément coulissant. Une autre variante consisterait à remplacer la transmission à crémaillère 37 et pignon 6 par un engagement permanent de la goupille 40 dans une fente oblique ménagée dans la roue de déclenchement 4, de sorte que tout déplacement radial de la goupille produirait un pivotement de cette roue et vice versa.The construction described above can obviously be modified without losing the essential functional feature of rotating the trigger wheel relative to the programming wheel to trigger the ring. For example, the lever 8 could possibly be replaced by a sliding element. Another variant would be to replace the rack transmission 37 and pinion 6 by a permanent engagement of the pin 40 in an oblique slot in the trigger wheel 4, so that any radial displacement of the pin would produce a pivoting of the wheel and vice versa .

Par ailleurs, on notera que le concept de base de l'invention est applicable sans répétition de la sonnerie après quelques minutes, et même sans utilisation d'une came des minutes, si l'on se contente d'une moindre précision de l'heure de réveil.Furthermore, it should be noted that the basic concept of the invention is applicable without repetition of the ring after a few minutes, and even without the use of a minute cam, if one is satisfied with a lesser precision of the waking hour.
