Description
La présente invention concerne le domaine desThe present invention relates to the field of
montres, et plus particulièrement des montres-bracelet. La première montre connue a été fabriquée en 1504 par Peter Henlein, un horloger de Nuremberg (Allemagne). Son 5 mécanisme est encore celui d'une horloge, mais ses composants étaient suffisamment petits pour qu'on puisse glisser l'appareil dans une petite poche appelée gousset. watches, and more particularly wrist watches. The first known watch was produced in 1504 by Peter Henlein, a clockmaker from Nuremberg (Germany). Its mechanism is still that of a clock, but its components were small enough that one could slip the device into a small pocket called a gusset.
L'utilisation du ressort d'acier enroulé en spirale inventé en 1675 par le Hollandais Christiaan 10 Huygens permettra de miniaturiser encore les montres. The use of the spiral wound steel spring invented in 1675 by the Dutchman Christiaan 10 Huygens will allow the watches to be further miniaturized.
Jusque vers les années 1970, c'est ce ressort qui servira de "moteur" à toutes les montres. Il fallait donc remonter régulièrement les montres mécaniques pour comprimer ce ressort Ce n'est que vers 1900 que la montrebracelet (que l'on porte au poignet) inventé simultanément par Louis Cartier et Hans Wildorf, fondateur de l'entreprise Rolex (marque commerciale), s'imposera. Until around the 1970s, it was this spring that served as the "engine" for all watches. Mechanical watches had to be wound regularly to compress this spring. It was not until around 1900 that the wristwatch (worn on the wrist) invented simultaneously by Louis Cartier and Hans Wildorf, founder of the Rolex company (commercial brand) , will prevail.
En 1922, un Londonien inventa la montre 20 automatique qui se remontait toute seule grâce au mouvement du poignet de celui qui portait la montre. In 1922, a Londoner invented the automatic 20 watch which wound itself by the movement of the wrist of the wearer.
Chaque mouvement entraînait une petite masselotte articulée qui comprimait le ressort. Each movement resulted in a small articulated flyweight which compressed the spring.
Depuis, on a cherché à améliorer de telles 25 montres, en particulier en prévoyant un fond transparent permettant d'observer le fonctionnement du mécanisme. Since then, attempts have been made to improve such watches, in particular by providing a transparent bottom allowing the operation of the mechanism to be observed.
A titre d'exemple, le brevet PCT W09957613 décrit une montre-bracelet comportant une masse de remontage oscillante pour pièce d'horlogerie à mouvement 30 automatique. La masse est aménagée du côté du fond de la boîte et permettant l'observation de la totalité du mouvement en permanence. By way of example, PCT patent WO9957613 describes a wristwatch comprising an oscillating winding weight for a timepiece with automatic movement. The mass is arranged on the bottom side of the box and allowing the observation of the entire movement at all times.
Lorsque ces montres à fond transparent comportent un mouvement à remontage automatique, l'observation du mouvement est toujours tronquée par la présence de la masse de remontage oscillante qui, même 5 ajourée, comme c'est le cas dans les montres dites "squelettes", empêche une observation confortable du mouvement. When these watches with transparent bottom include an automatic winding movement, the observation of the movement is always truncated by the presence of the oscillating winding mass which, even if perforated, as is the case in so-called "skeleton" watches, prevents comfortable observation of movement.
Le brevet de l'art antérieur a proposé pour remédier à ce problème une masse de remontage oscillante 10 pour pièce d'horlogerie comprenant une partie pesante fixée à un organe de liaison reliant ladite partie pesante à un axe solidaire d'un mouvement, ladite masse étant destinée à être montée à rotation sur ledit axe, caractérisée en ce que ledit organe de liaison est réalisé 15 en un matériau transparent ou translucide. Ceci permettait de rendre visible en permanence la totalité du mouvement de la pièce d'horlogerie qu'elle équipe, ce qui confère à celle-ci un aspect esthétique amélioré. L'organe de liaison est par exemple formé d'un disque plein en saphir 20 dans cette solution de l'art antérieur. The patent of the prior art has proposed to remedy this problem an oscillating winding weight 10 for a timepiece comprising a heavy part fixed to a connecting member connecting said heavy part to an axis secured to a movement, said mass being intended to be rotatably mounted on said axis, characterized in that said connecting member is made of a transparent or translucent material. This made it possible to make the entire movement of the timepiece which it fitted permanently visible, which gave it an improved aesthetic appearance. The connecting member is for example formed of a solid sapphire disc 20 in this solution of the prior art.
Cette solution n'est pas satisfaisante, comme le reconnaît d'ailleurs l'inventeur de cette solution de l'art antérieur, car il n'est pas possible de concilier pleinement les exigences mécaniques et les 25 exigences esthétiques, et la solution de l'art antérieur aboutit à des compromis difficilement acceptables dans l'horlogerie de luxe. This solution is not satisfactory, as recognized by the inventor of this solution of the prior art, because it is not possible to fully reconcile the mechanical requirements and the aesthetic requirements, and the solution of the he prior art leads to compromises that are difficult to accept in luxury watchmaking.
La présente invention vise à remédier à cet inconvénient en proposant selon son acception la plus 30 générale une montre-bracelet à remontage par masselotte oscillante caractérisée en ce que ladite masselotte présente une forme annulaire une répartition dissymétrique des masses, ladite masselotte présentant des surfaces de guidages périphériques et une zone crantée pour la transmission des mouvements d'oscillation, la zone centrale de la masselotte étant évidée. The present invention aims to remedy this drawback by proposing, according to its most general meaning, a wristwatch with winding by oscillating weight, characterized in that said weight has an annular shape, an asymmetrical distribution of the masses, said weight having guide surfaces. peripherals and a notched zone for the transmission of the oscillating movements, the central zone of the counterweight being hollowed out.
Cette solution présente de nombreux avantages. 5 Le poids suspendu d'un balancier est dans l'état de l'art limité par la résistance de la partie de liaison qui a tendance à fléchir sous les chocs, voire à se tordre, permettant alors à la masselotte de venir frotter sur le mouvement. La faire plus lourde oblige à faire la liaison 10 plus épaisse, ce qui oblige à augmenter la hauteur du mouvement, ce qui est contraire au but de compacité habituellement recherché. This solution has many advantages. 5 The suspended weight of a pendulum is in the state of the art limited by the resistance of the connecting part which tends to bend under impact, or even to twist, then allowing the flyweight to come and rub on the movement. Making it heavier obliges to make the link 10 thicker, which obliges to increase the height of the movement, which is contrary to the purpose of compactness usually sought.
Un guidage type roulement à billes périphérique permet de "charger" au maximum la masselotte 15 sans aucun danger mécanique, donc d'avoir plus d'inertie, donc de mouvoir remonter un ressort plus puissant ou plus vite, donc de disposer de plus de réserve de marche rapidement ou de puissance, au choix. D'autre part, la place ou la masselotte se développe est peu encombrée, et 20 l'augmentation en diamètre du mouvement est beaucoup moins pénalisante que son augmentation en hauteur. A peripheral ball bearing type guide makes it possible to "load" the flyweight 15 as much as possible without any mechanical danger, therefore to have more inertia, therefore to move up a more powerful spring or faster, therefore to have more reserve fast walking or power, your choice. On the other hand, the space where the flyweight develops is not very congested, and the increase in diameter of the movement is much less penalizing than its increase in height.
De préférence, la masselotte présente un balourd semi-annulaire. Preferably, the counterweight has a semi-annular unbalance.
De préférence, la montre présente au moins 25 trois points, galets ou roulements à bille latéraux assurant le guidage du bord extérieur de la masselotte. Preferably, the watch has at least three points, rollers or lateral ball bearings ensuring the guiding of the outer edge of the counterweight.
Selon une variante avantageuse, la masselotte présente une nervure annulaire et en ce que les galets présente une gorge de forme complémentaire à ladite 30 nervure. According to an advantageous variant, the counterweight has an annular rib and in that the rollers has a groove of shape complementary to said rib.
Selon un exemple de réalisation, la masselotte présente la forme d'une couronne annulaire, et en ce que le balourd est formé par une surépaisseur locale de ladite couronne annulaire. According to an exemplary embodiment, the counterweight has the shape of an annular crown, and in that the unbalance is formed by a local excess thickness of said annular crown.
Selon une première variante, la masselotte est adjacente au fond du boîtier. According to a first variant, the counterweight is adjacent to the bottom of the housing.
Selon une deuxième variante, la masselotte est disposée du côté du cadran de la montre. According to a second variant, the counterweight is arranged on the side of the watch dial.
L'invention sera mieux comprise à la lecture de la description qui suit, se référant aux dessins annexés correspondant à des exemples non limitatifs de 10 réalisation, o : - la figure 1 représente une vue de derrière d'une montre selon l'invention - la figure 2 représente une vue en perspective du moteur de montre 15 - la figure 3 représente une vue selon un plan de coupe transversal AA - la figure 4 représente une vue selon un plan de coupe transversal d'une variante de réalisation - la figure 5 représente une vue arrière de la montre. The invention will be better understood on reading the description which follows, referring to the appended drawings corresponding to nonlimiting exemplary embodiments, o: - Figure 1 represents a back view of a watch according to the invention - FIG. 2 represents a perspective view of the watch motor 15 - FIG. 3 represents a view according to a transverse cutting plane AA - FIG. 4 represents a view according to a transverse cutting plane of an alternative embodiment - FIG. 5 represents a rear view of the watch.
- les figures 6 à 8 représentent une variante de réalisation. - Figures 6 to 8 show an alternative embodiment.
La montre représentée dans les exemples 25 illustrés par dessins annexés comporte un moteur (1) de type connu comprenant un balancier-spiral (2) assurant la régulation, un barillet contenant le ressort d'accumulation d'énergie étant logé à l'intérieur du moteur (1),le tout à l'intérieur dans un boîtier (3). The watch shown in the examples 25 illustrated by appended drawings comprises a motor (1) of known type comprising a balance-spring (2) ensuring regulation, a barrel containing the energy accumulation spring being housed inside the motor (1), all inside in a housing (3).
La masselotte (4) est formée par une couronne annulaire évidée en sa partie centrale. Elle est guidée en rotation par trois galets (5, 6, 7) angulairement espacés de 1200 ou roulement à billes ou tout autre moyen de guidage en rotation. The counterweight (4) is formed by an annular crown hollowed out in its central part. It is guided in rotation by three rollers (5, 6, 7) angularly spaced by 1200 or ball bearing or any other means for guiding in rotation.
Ces galets (5 à 7) présentent une gorge périphérique (9) d'une section complémentaire d'une 5 nervure (8) prévue sur la périphérie de la masselotte. These rollers (5 to 7) have a peripheral groove (9) of a complementary section of a rib (8) provided on the periphery of the counterweight.
L'épaisseur de cette nervure (8) correspond sensiblement au tiers de la hauteur de la zone la plus mince de la masselotte. La section de cette nervure (8) peut être trapézoïdale, ou concave. The thickness of this rib (8) corresponds substantially to a third of the height of the thinnest region of the counterweight. The section of this rib (8) can be trapezoidal, or concave.
Le bord intérieur de la couronne annulaire supportant la masselotte présente une zone crantée (10) coopérant avec une roue dentée (11) entraînant le train d'engrenages du système de réarmement du ressort de barillet. The inner edge of the annular ring supporting the counterweight has a notched area (10) cooperating with a toothed wheel (11) driving the gear train of the barrel spring reset system.
Cette zone crantée s'étend dans l'exemple décrit sur la totalité du périmètre intérieur. This notched zone extends in the example described over the entire interior perimeter.
La partie complémentaire de la masselotte présente une épaisseur supérieure à l'épaisseur de la zone crantée (10). Cette surépaisseur (13) produit un balourd 20 générant les oscillations lors des mouvements du bras du porteur de la montre-bracelet. The complementary part of the counterweight has a thickness greater than the thickness of the notched zone (10). This extra thickness (13) produces an unbalance 20 generating the oscillations during the movements of the arm of the wearer of the wristwatch.
La masselotte peut être à titre de variante prévue pour être visible par la face avant de la montre, comme dans l'exemple illustré par la figure 4. The counterweight may alternatively be designed to be visible from the front face of the watch, as in the example illustrated in FIG. 4.
La masselotte présente dans les deux exemples de réalisation décrits une zone crantée (10) occupant 3600 de la périphérie intérieure de la couronne annulaire, sur une hauteur correspondant à environ la moitié de la hauteur. Le balourd s'étend sur la moitié de la 30 périphérie, soit environ 1800, et présente une largeur radiale supérieure à celle de la zone complémentaire. La largeur radiale est déterminée pour permettre le passage au niveau de l'axe (15) de la roue dentée (11). Le rayon de cette roue dentée est déterminé pour laisser un espace suffisant pour le passage du balourd. The flyweight has in the two embodiments described a notched area (10) occupying 3600 of the inner periphery of the annular ring, over a height corresponding to about half the height. The unbalance extends over half of the periphery, that is to say approximately 1800, and has a radial width greater than that of the complementary zone. The radial width is determined to allow passage at the axis (15) of the toothed wheel (11). The radius of this gear is determined to leave sufficient space for the passage of the unbalance.
Les figures 6 à 8 représentent une variante de réalisation dans laquelle les galets (5 à 7) sont remplacés par un roulement à bille (20). Figures 6 to 8 show an alternative embodiment in which the rollers (5 to 7) are replaced by a ball bearing (20).
