Description

MECAN ISME GENERATEU R D'AU MO I NS U NE SONORITE MECAN ISME GENERATEU R FROM THE WORLD
La présente invention concerne un mécanisme apte à produire au moins une sonorité et destiné à équiper, par exemple, une pièce d'horlogerie telle qu'une montre- bracelet.The present invention relates to a mechanism capable of producing at least one sound and intended to equip, for example, a timepiece such as a wristwatch.
Un mécanisme de sonnerie couramment employé dans les montres-bracelets comprend un marteau qui vient frapper un timbre. Le marteau est écarté de sa position de repos puis relâché et vient frapper la racine du timbre qui est disposé en cercle autour du mouvement. Un inconvénient d'un tel mécanisme de sonnerie est que l'intensité du son produit est faible.A striking mechanism commonly used in wristwatches includes a hammer striking a stamp. The hammer is removed from its rest position and released and hits the root of the stamp which is arranged in a circle around the movement. A disadvantage of such a striking mechanism is that the intensity of the sound produced is low.
Un second type de mécanisme de sonnerie s'apparente aux mécanismes de sonnerie utilisés dans les boîtes à musique. Un tel mécanisme est schématiquement représenté à la figure 1 annexée à la présente demande de brevet. Ce mécanisme, désigné dans son ensemble par la référence numérique générale 1 , comprend pour l'essentiel un tambour rotatif 2 à la surface duquel sont prévus des ergots 4. Lorsque le tambour 2 tourne, un des ergots 4 vient soulever un timbre 6 et l'écarté progressivement de sa position de repos jusqu'au moment où le timbre 6 échappe à l'ergot 4 et se détend brusquement. En se détendant, le timbre 6 vibre et produit un son. Un tel mécanisme a comme avantage de produire des sons de plus forte intensité. Toutefois, l'entraînement du tambour rotatif 2 requiert une énergie importante, ce qui rend un tel mécanisme difficile à intégrer dans une montre qui ne dispose que d'une faible réserve d'énergie.A second type of striking mechanism is similar to the striking mechanisms used in music boxes. Such a mechanism is schematically represented in FIG. 1 appended to the present patent application. This mechanism, generally designated by the general reference numeral 1, essentially comprises a rotary drum 2 on the surface of which are provided lugs 4. When the drum 2 rotates, one of the lugs 4 comes to raise a stamp 6 and the progressively moved away from its rest position until the stamp 6 escapes the lug 4 and relaxes suddenly. By relaxing, the timbre 6 vibrates and produces a sound. Such a mechanism has the advantage of producing sounds of higher intensity. However, the driving of the rotary drum 2 requires a high energy, which makes such a mechanism difficult to integrate in a watch that has only a small reserve of energy.
La présente invention a pour but de remédier aux inconvénients susmentionnés ainsi qu'à d'autres encore en procurant un mécanisme générateur de sons pouvant facilement être intégré par exemple dans une montre-bracelet et produisant un son de forte intensité. A cet effet, la présente invention concerne un mécanisme générateur de sons comprenant un organe de commande, un organe vibrant et un mécanisme de blocage/déblocage de l'organe de commande, l'organe de commande étant apte à se déplacer entre une première position dans laquelle il est retenu par le mécanisme de blocage/déblocage et dans laquelle il maintient l'organe vibrant écarté de sa position de repos, et une seconde position dans laquelle il est libéré par le mécanisme de blocage/déblocage et dans laquelle il libère simultanément l'organe vibrant qui se met à vibrer et à produire un son.The present invention aims to overcome the aforementioned drawbacks as well as others by providing a sound generating mechanism that can easily be integrated for example in a wristwatch and producing a high intensity sound. For this purpose, the present invention relates to a sound generating mechanism comprising a control member, a vibrating member and a locking / unlocking mechanism of the control member, the control member being able to move between a first position. in which it is retained by the locking / unlocking mechanism and in which it keeps the vibrating member spaced from its rest position, and a second position in which it is released by the locking / unlocking mechanism and in which it releases simultaneously the vibrating organ that starts to vibrate and produce a sound.
Grâce à ces caractéristiques, la présente invention procure un mécanisme générateur de sons qui, en écartant l'organe vibrant de sa position de repos puis en le relâchant brusquement, est capable de produire un son de forte intensité. Selon une caractéristique complémentaire de l'invention, le mécanisme générateur de sons est armé par une action de l'utilisateur et est déclenché lorsqu'un processus temporel arrive à son terme.Thanks to these characteristics, the present invention provides a sound generating mechanism which, by removing the vibrating member from its rest position and then releasing it suddenly, is capable of producing a high intensity sound. According to an additional characteristic of the invention, the sound generating mechanism is armed by an action of the user and is triggered when a temporal process comes to an end.
Selon une autre caractéristique de l'invention, l'organe de commande se déplace en pivotant entre ses première et deuxième positions.According to another characteristic of the invention, the control member moves by pivoting between its first and second positions.
Selon encore une autre caractéristique de l'invention, l'organe de commande comprend une came et le mécanisme de blocage/déblocage comprend un ressort à cran d'arrêt.According to yet another characteristic of the invention, the control member comprises a cam and the locking / unlocking mechanism comprises a detent spring.
Il suffit donc, pour libérer la came et produire un son, d'agir sur un élément ressort, ce qui nécessite peu d'énergie et rend le mécanisme générateur de sons selon l'invention particulièrement facile à intégrer dans une montre-bracelet par exemple.It is therefore sufficient, to release the cam and produce a sound, to act on a spring element, which requires little energy and makes the sound generating mechanism according to the invention particularly easy to integrate into a wristwatch for example .
D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suit d'un mode de réalisation du mécanisme générateur de sons selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement, en liaison avec le dessin annexé sur lequel :Other features and advantages of the present invention will emerge more clearly from the detailed description which follows of an embodiment of the sound generating mechanism according to the invention, this example being given purely by way of illustration and not limiting only, in connection with with the attached drawing in which:
- la figure 1 , déjà citée, est une représentation schématique d'un mécanisme de sonnerie de l'art antérieur; - la figure 2a est une représentation schématique en coupe du mécanisme générateur de sons conforme à la présente invention en position bloquée, et- Figure 1, already mentioned, is a schematic representation of a striking mechanism of the prior art; FIG. 2a is a schematic sectional representation of the sound generating mechanism according to the present invention in the locked position, and
- la figure 2b est une vue analogue à celle de la figure 2a représentant le mécanisme générateur de sons dans l'état débloqué.- Figure 2b is a view similar to that of Figure 2a showing the sound generating mechanism in the unlocked state.
La présente invention procède de l'idée générale inventive qui consiste à procurer un mécanisme générateur de sons apte à produire des sons de forte intensité tout en ne nécessitant que peu d'énergie pour son déclenchement, ce qui rend un tel objet particulièrement facile à intégrer dans un objet portable tel que, par exemple, une montre-bracelet. A cet effet, le mécanisme générateur de sons selon l'invention comprend un organe de commande qui, dans une première position bloquée, écarte un organe vibrant de sa position de repos et qui, dans une seconde position débloquée, libère l'organe vibrant qui se met à vibrer et à produire un son de forte intensité.The present invention proceeds from the general inventive idea of providing a sound generating mechanism capable of producing high intensity sounds while requiring little energy for its triggering, which makes such an object particularly easy to integrate. in a portable object such as, for example, a wristwatch. For this purpose, the sound generating mechanism according to the invention comprises a control member which, in a first locked position, separates a vibrating member from its rest position and which, in a second unlocked position, releases the vibrating member which vibrates and produces a high intensity sound.
Désigné dans son ensemble par la référence numérique générale 8, le mécanisme générateur de sons selon l'invention représenté en coupe à la figure 2a comprend pour l'essentiel un organe de commande 10, un organe vibrant 12 et un mécanisme de blocage/déblocage 14. Plus précisément, l'organe de commande 10 se présente sous la forme d'une came munie de deux ergots 16a et 16b diamétralement opposés. Le mécanisme de blocage/déblocage 14 se présente quant à lui sous la forme d'une lame ressort fixée à l'une de ses extrémités et présentant un cran d'arrêt 18 à son extrémité libre. Enfin, l'organe vibrant 12 est constitué par un timbre en forme de lame. Comme on peut le voir à l'examen des figures, la came 10 est montée pivotante sur un arbre moteur 20. A cet effet, la came 10 présente une lumière 22 formée d'un passage central cylindrique 22a par lequel ladite came 10 est montée sur l'arbre moteur 20 et de deux découpes en arc de cercle 22b qui débouchent dans le passage central 22a. La came 10 est couplée avec l'arbre moteur 20 par le biais d'un organe de retenue 24 tel qu'une clavette solidaire de l'arbre moteur 20 et dont le rôle est décrit ci-dessous.Designated as a whole by the general numerical reference 8, the sound generator mechanism according to the invention shown in section in FIG. 2a essentially comprises a control member 10, a vibrating member 12 and a locking / unlocking mechanism 14 More specifically, the control member 10 is in the form of a cam provided with two lugs 16a and 16b diametrically opposed. The locking / unlocking mechanism 14 is in turn in the form of a leaf spring fixed at one of its ends and having a detent 18 at its free end. Finally, the vibrating member 12 is constituted by a blade-shaped stamp. As can be seen from the figures, the cam 10 is pivotally mounted on a motor shaft 20. For this purpose, the cam 10 has a slot 22 formed of a cylindrical central passage 22a through which said cam 10 is mounted on the motor shaft 20 and two arcuate cuts 22b which open into the central passage 22a. The cam 10 is coupled with the motor shaft 20 by means of a retaining member 24 such as a key integral with the motor shaft 20 and whose role is described below.
Dans la position représentée à la figue 2a, la came 10 est bloquée, l'un de ses ergots 16a butant contre le cran d'arrêt 18 de la lame ressort 14, tandis que par son autre ergot 16b, la came 10 maintient le timbre 12 écarté de sa position de repos horizontale représentée en traits mixtes par exemple selon un angle α d'environ 18°. A la fin d'un processus temporel tel que le comptage du temps avant la coïncidence de l'heure courante avec une heure d'alarme, un mécanisme moteur (non représenté) qui peut être entraîné par le mouvement de la montre écarte le ressort 14 vers le bas selon la flèche A. La came 10 n'étant plus bloquée, elle est libre de pivoter dans le sens horaire selon la flèche B sous l'effet de la force de flexion exercée par le timbre 12 qui cherche à regagner sa position de repos horizontale en se déplaçant selon la flèche C. Pour faciliter le mouvement relatif de la came 10 et du timbre 12, le timbre 12 présente avantageusement à son extrémité libre une surépaisseur dans laquelle est ménagé un plan incliné 26 le long duquel l'ergot 16b peut glisser. Libéré de l'emprise de la came 10, le timbre 12 regagne sa position horizontale de repos en vibrant et en émettant un signal sonore de forte intensité. Comme on l'aura compris, la seule énergie nécessaire pour déclencher le mécanisme générateur de sons selon l'invention est celle qu'il faut fournir pour écarter le ressort 14 de la position dans laquelle il bloque la came 10. La quantité d'énergie à fournir est donc très faible, ce qui permet d'envisager aisément l'intégration du mécanisme selon l'invention par exemple dans une montre qui, comme on le sait, ne peut stocker qu'une quantité d'énergie très limitée.In the position shown in Fig 2a, the cam 10 is locked, one of its lugs 16a abutting against the detent 18 of the leaf spring 14, while its other lug 16b, the cam 10 maintains the stamp 12 spaced from its horizontal rest position shown in phantom for example at an angle α of about 18 °. At the end of a time process such as counting the time before the coincidence of the current time with an alarm time, a motor mechanism (not shown) that can be driven by the movement of the watch moves the spring 14 downwards according to the arrow A. The cam 10 is no longer locked, it is free to rotate clockwise according to the arrow B under the effect of the bending force exerted by the stamp 12 which seeks to regain its position horizontal rest by moving along the arrow C. To facilitate the relative movement of the cam 10 and the stamp 12, the stamp 12 advantageously has at its free end an extra thickness in which is formed an inclined plane 26 along which the pin 16b can slide. Released from the grip of the cam 10, the stamp 12 returns to its horizontal rest position by vibrating and emitting a loud sound signal. As will have been understood, the only energy necessary to trigger the sound generating mechanism according to the invention is that which must be provided to move the spring 14 away from the position in which it blocks the cam 10. The quantity of energy to provide is very low, which allows to easily consider the integration of the mechanism according to the invention for example in a watch which, as we know, can store only a very limited amount of energy.
Comme on l'a vu ci-dessus, lorsque le ressort à cran d'arrêt 14 libère la came 10, celle-ci pivote dans le sens horaire selon la flèche B. La came 10 est toutefois limitée dans son mouvement de pivotement par l'organe de retenue 24 qui est solidaire de l'arbre moteur 20 et qui vient buter en fond des découpes en arc de cercle 22b formées dans la lumière 22 (voir figure 2b). L'angle de pivotement β de la came est d'environ 35°.As seen above, when the detent spring 14 releases the cam 10, it rotates clockwise according to the arrow B. The cam 10 is, however, limited in its pivoting movement by the cam. retaining member 24 which is integral with the motor shaft 20 and which abuts in the bottom of cuts in a circular arc 22b formed in the light 22 (see Figure 2b). The pivot angle β of the cam is approximately 35 °.
Le réarmage du mécanisme générateur de sons selon l'invention est effectué par l'utilisateur qui peut, par exemple, exercer une pression sur un bouton, pression sous l'effet de laquelle l'arbre moteur 20 effectue un déplacement de 180°. La came 10 ayant pivoté d'environ 35° et étant venue buter par les bords de ses découpes en arc de cercle 22b contre l'élément de retenue 24, l'arbre moteur 20 ne commencera à entraîner la came 10 que lorsque l'élément de retenue viendra buter contre les bords opposés des découpes en arc de cercle 22b ménagées dans la lumière 22. Tandis que l'arbre moteur 20 effectuera une rotation de 180°, la came 10 ne se déplacera quant à elle que de 180 - 35 = 135° pour revenir dans sa position initiale illustrée à la figure 2a.The rearrangement of the sound generating mechanism according to the invention is carried out by the user who can, for example, exert pressure on a button, under the effect of which the motor shaft 20 performs a movement of 180 °. With the cam 10 pivoted about 35 ° and being abutted by the edges of its arcuate cuts 22b against the retaining element 24, the motor shaft 20 will start to drive the cam 10 only when the element retaining will abut against the opposite edges of the arcuate cutouts 22b formed in the slot 22. While the motor shaft 20 will rotate 180 °, the cam 10 will move for it only 180 - 35 = 135 ° to return to its initial position shown in Figure 2a.
On notera que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de la présente invention tel que défini par les revendications annexées. En particulier, il peut être envisagé que l'opération d'armage du mécanisme générateur de sons selon l'invention soit réalisée au moyen d'un moteur. Il est également envisageable de disposer en parallèle plusieurs mécanismes conformes à l'invention mais dont les fréquences des sons produits par les timbres respectifs sont différentes afin de générer une mélodie. It should be noted that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the present invention as defined by the appended claims. In particular, it can be envisaged that the arming operation of the sound generating mechanism according to the invention is carried out by means of a motor. It is also conceivable to have in parallel several mechanisms according to the invention but whose frequencies of the sounds produced by the respective timbres are different in order to generate a melody.
