Description

La présente invention se rapporte aux masses de remontage automatiques pivotantes ou oscillantes pivotées sur l'extérieur d'un mouvement d'horlogerie ainsi qu'aux mouvements d'horlogerie à remontage automatique équipés d'une telle masse oscillante ou pivotante.The present invention relates to automatic rotating or oscillating winding masses pivoted on the outside of a clockwork movement as well as self-winding watch movements equipped with such an oscillating or pivoting mass.

On connaît une telle masse oscillante du document DE 10 2009 005 690 qui comporte un anneau circulaire dont la tranche interne est munie d'une denture destinée à être reliée cinématiquement au rochet d'un barillet. La face supérieure de cet anneau circulaire porte la masse de remontage proprement dite qui se présente sous la forme d'un secteur de couronne d'une envergure angulaire de préférence de 180°.Such an oscillating weight of the document is known DE 10 2009 005 690 which comprises a circular ring whose inner edge is provided with a toothing intended to be kinematically connected to the ratchet of a barrel. The upper face of this circular ring carries the winding mass itself which is in the form of a crown sector with an angular span preferably of 180 °.

A moins d'augmenter considérablement la hauteur ou le diamètre d'un mouvement équipé d'une telle masse de remontage automatique pivotée à l'extérieur du mouvement, le pouvoir et l'efficacité du système de remontage automatique est faible, les dimensions et donc le poids de la masse étant forcément réduits.Unless the height or diameter of a movement equipped with such an automatic winding mass is increased to the outside of the movement, the power and efficiency of the automatic winding system is small, the dimensions and therefore the weight of the mass being necessarily reduced.

On connaît également du document CH 458213 une masse oscillante destinée à être pivotée par un roulement à billes sur l'extérieur d'un mouvement d'horlogerie. Cette masse a également la forme d'un secteur annulaire avec une étendue angulaire de l'ordre de 180°. Toutefois cette réalisation souffre des mêmes défauts énoncés précédemment en relation avec la réalisation décrite dans le document DE 10 2009 005 690 .Document is also known CH 458213 an oscillating mass intended to be pivoted by a ball bearing on the outside of a clockwork movement. This mass also has the shape of an annular sector with an angular extent of the order of 180 °. However, this embodiment suffers from the same defects previously stated in relation with the embodiment described in the document DE 10 2009 005 690 .

Le but de la présente invention est de permettre la réalisation d'un mouvement d'horlogerie à remontage automatique dont la masse oscillante est pivotée à l'extérieur du mouvement puisse avoir un poids supérieur pour un encombrement donné par le diamètre et la hauteur du mouvement d'horlogerie de manière à réaliser un mécanisme de remontage automatique plus puissant et efficace que les dispositifs connus.The object of the present invention is to allow the realization of a self-winding watch movement whose oscillating weight is rotated outside the movement can have a greater weight for a given size given by the diameter and the height of the movement. watchmaking to realize an automatic winding mechanism more powerful and effective than known devices.

Un autre but de la présente invention est de procurer, par la forme de la masse oscillante pivotée à l'extérieur d'un mouvement d'horlogerie, un effet visuel et esthétique dudit mouvement qui soit nouveau, ludique et attrayant.Another object of the present invention is to provide, by the shape of the oscillating mass pivoted outside a clockwork movement, a visual and aesthetic effect of said movement that is new, fun and attractive.

La présente invention a pour objet une masse oscillante destinée à être pivotée sur l'extérieur d'un mouvement d'horlogerie comportant un cadre annulaire et une partie centrale située, majoritairement ou exclusivement dans une moitié de la surface délimitée par le cadre annulaire, constituant un balourd.The subject of the present invention is an oscillating mass intended to be pivoted on the outside of a watch movement comprising an annular frame and a central part situated, predominantly or exclusively, in one half of the surface delimited by the annular frame constituting an imbalance.

La présente invention a encore pour objet un mouvement d'horlogerie, notamment de montre bracelet, comportant un mécanisme de remontage automatique équipé d'une telle masse oscillante.The present invention also relates to a watch movement, in particular a wristwatch, comprising an automatic winding mechanism equipped with such an oscillating weight.

Le dessin annexé illustre schématiquement et à titre d'exemple une masse oscillante destinée à être pivotée à l'extérieur d'un mouvement d'horlogerie et partiellement un mouvement d'horlogerie équipé d'une telle masse oscillante.

  • La figure 1 est une vue en perspective de la masse oscillante pivotée à l'extérieur d'un mouvement d'horlogerie par un roulement à billes.
  • La figure 2 est une vue éclatée partielle d'un mouvement d'horlogerie équipé d'une masse oscillante pivotée à l'extérieur dudit mouvement.
  • La figure 3 est une vue en coupe partielle d'un mouvement d'horlogerie équipé d'une masse oscillante pivotée à l'extérieur dudit mouvement.
The accompanying drawing illustrates schematically and by way of example an oscillating mass intended to be pivoted outside a watch movement and partially a clockwork movement equipped with such an oscillating mass.
  • The figure 1 is a perspective view of the oscillating mass rotated outside a watch movement by a ball bearing.
  • The figure 2 is a partial exploded view of a clockwork movement equipped with an oscillating mass pivoted outside said movement.
  • The figure 3 is a partial sectional view of a clockwork movement equipped with an oscillating mass pivoted outside said movement.

La figure 1 illustre en perspective une forme d'exécution d'une masse oscillante selon l'invention fixée sur la cage intérieure d'un roulement à billes dont la cage extérieure 2 est fixée sur la partie périphérique de la platine 3 d'un mouvement d'horlogerie, notamment d'une montre bracelet.The figure 1 illustrates in perspective a form of execution of an oscillating mass according to the invention fixed on the inner race of a ball bearing whose outer cage 2 is fixed on the peripheral part of the plate 3 of a watch movement , including a wristwatch.

Cette masse oscillante comporte un cadre annulaire 4 destiné à être fixé par des vis 5 sur la partie supérieure de la cage intérieure 1 d'un roulement à billes. Dans la forme d'exécution illustrée (comme on le voit particulièrement bien sur la figure 2), le cadre annulaire 4 comporte une partie plus épaisse (et donc plus lourde) et une partie plus mince (et donc plus légère), et il est également muni d'ouvertures 6 dans et le long de la partie plus mince et légère. De cette manière, le poids du cadre annulaire 4 n'est pas distribué uniformément, et le cadre annulaire présente donc un balourd. L'effet de balourd peut également être obtenu par d'autres moyens connus par l'homme de métier - par exemple en utilisant des matériaux de poids différents pour les parties plus lourde et plus légère respectivement (soit à la place soit en combinaison avec les moyens sus-décrits).This oscillating mass comprises an annular frame 4 intended to be fixed by screws 5 on the upper part of the inner race 1 of a ball bearing. In the illustrated embodiment (as seen particularly well on the figure 2 ), the annular frame 4 has a thicker part (and therefore heavier) and a thinner (and therefore lighter) part, and it is also provided with openings 6 in and along the thinner and lighter part. In this way, the weight of the annular frame 4 is not uniformly distributed, and the annular frame therefore has an unbalance. The unbalance effect can also be achieved by other means known to those skilled in the art - for example by using materials of different weights for the heavier and lighter parts respectively (either instead or in combination with the means described above).

Cette masse oscillante comporte encore une partie centrale 7 située majoritairement voire exclusivement dans la partie de la surface délimitée par la partie plus lourde du cadre annulaire 4. Cette partie centrale 7 est fixée en un ou plusieurs points à la partie plus lourde du cadre annulaire 4. De préférence, la partie centrale 7 est située majoritairement ou exclusivement dans une moitié de la surface délimitée par le cadre annulaire 4. Cette partie centrale 7 de la masse oscillante peut bien évidemment également être venue d'une seule pièce de fabrication avec le cadre extérieur annulaire 4.This oscillating mass also comprises a central portion 7 located mainly or exclusively in the part of the surface defined by the heavier portion of the annular frame 4. This central portion 7 is fixed at one or more points to the heavier portion of the annular frame 4 Preferably, the central portion 7 is located mainly or exclusively in one half of the surface defined by the annular frame 4. This central portion 7 of the oscillating mass can of course also come from a single workpiece with the frame outer ring 4.

De cette façon, la masse oscillante peut présenter un balourd important (qui, de préférence, s'ajoute au balourd du cadre 4), correspondant au moins au poids de la partie centrale 7 de la masse oscillante ce qui assure une puissance et une efficacité augmentée de la masse oscillante pour le remontage d'un mécanisme de remontage automatique d'un mouvement d'horlogerie.In this way, the oscillating mass may have a large unbalance (which, preferably, adds to the unbalance of the frame 4), corresponding at least to the weight of the central portion 7 of the oscillating mass which ensures power and efficiency increased by the oscillating weight for the reassembly of an automatic winding mechanism of a clockwork movement.

La partie centrale de la masse oscillante peut présenter une forme quelconque mais représente, de préférence, une figurine par exemple une panthère dans la variante illustrée.The central portion of the oscillating mass may have any shape but preferably represents a figurine for example a panther in the illustrated variant.

Dans une telle masse oscillante, le balourd est de beaucoup supérieur à une masse oscillante annulaire ou en forme de secteur annulaire telle que connue actuellement. De préférence, la partie centrale 7 de la masse occupe au maximum la moitié de la surface délimitée par le cadre annulaire 4 de la masse oscillante, mais pour certaines formes désirées de la partie centrale 7 cette dernière peut s'étendre dans l'autre moitié à condition que son effet de balourd ne soit pas affecté d'une façon importante.In such an oscillating mass, the unbalance is much greater than an annular oscillating mass or annular sector as currently known. Preferably, the central portion 7 of the mass occupies at most half of the area defined by the annular frame 4 of the oscillating mass, but for some desired shapes of the central portion 7 the latter may extend into the other half provided that its unbalance effect is not significantly affected.

Selon les variantes, le cadre de la masse peut comprendre un secteur annulaire avec une étendue angulaire inférieure à 360° (par exemple de l'ordre de 180°). Le poids d'un tel cadre peut être distribué uniformément ou il peut être plus léger vers ses bouts. La partie centrale de la masse peut être fixée ou liée à ce cadre comme décrit ci-dessus.According to the variants, the frame of the mass may comprise an annular sector with an angular extent less than 360 ° (for example of the order of 180 °). The weight of such a frame can be evenly distributed or it can be lighter towards its ends. The central portion of the mass may be attached or bonded to this frame as described above.

Les figures 2 et 3 illustrent schématiquement et partiellement un mouvement d'horlogerie équipé d'une masse oscillante telle que décrite plus haut.The figures 2 and 3 illustrate schematically and partially a clockwork movement equipped with an oscillating mass as described above.

La cage extérieure 2 du roulement à billes est fixée à l'aide de vis 8 sur la platine 3 du mouvement d'horlogerie. La cage intérieure 1 du roulement à billes comporte une partie supérieure cylindrique 1a entourant le cadran 9 du mouvement d'horlogerie dont la surface supérieure est située dans un plan parallèle au cadran 9 mais au-dessus des aiguilles 10,11 de l'affichage horaire du mouvement d'horlogerie.The outer race 2 of the ball bearing is fixed with screws 8 on the plate 3 of the clockwork movement. The inner race 1 of the ball bearing comprises a cylindrical upper part 1a surrounding the dial 9 of the watch movement whose upper surface is situated in a plane parallel to the dial 9 but above the hands 10, 11 of the time display. of the watch movement.

De préférence, la masse oscillante 4,7 est fixée par des vis 5 sur la partie cylindrique 1 a de la cage intérieure du roulement à billes de sorte que la partie centrale 7 de la masse oscillante se déplace au-dessus de l'aiguillage du mouvement d'horlogerie. De cette manière, la masse centrale 7 de la masse oscillante est telle qu'elle n'interfère pas avec l'axe ou les axes de l'aiguillage du mouvement mais se déplace au-dessus du cadran et de l'aiguillage.Preferably, the oscillating mass 4,7 is fixed by screws 5 on the cylindrical portion 1a of the inner race of the ball bearing so that the central portion 7 of the oscillating mass moves over the switch of the clockwork movement. In this way, the central mass 7 of the oscillating mass is such that it does not interfere with the axis or the axes of the switch of the movement but moves over the dial and the switch.

La forme de la partie centrale 7 de la masse oscillante est de préférence telle que, quelle que soit sa position angulaire par rapport au mouvement lors de son fonctionnement, le ou les axes de l'aiguillage de l'affichage horaire dudit mouvement se trouve toujours hors de l'aire de balayage de cette partie centrale 7 et donc de la masse oscillante 4,7.The shape of the central portion 7 of the oscillating mass is preferably such that, whatever its angular position relative to the movement during its operation, the axis or axes of the switch of the time display of said movement is always out of the scanning area of this central portion 7 and thus of the oscillating mass 4,7.

Ainsi, dans une variante d'exécution, le plan dans lequel se déplace la masse oscillante 4,7 peut être parallèle au cadran 9 mais situé entre ledit cadran 9 et les aiguilles 10,11. Dans une telle forme d'exécution, les aiguilles 10,11 sont en tout temps entièrement visibles pour l'utilisateur de la montre comportant une telle masse oscillante pour son mécanisme de remontage automatique.Thus, in an alternative embodiment, the plane in which the oscillating mass 4,7 moves may be parallel to the dial 9 but located between said dial 9 and the hands 10,11. In such an embodiment, the needles 10, 11 are in any time entirely visible to the user of the watch having such an oscillating weight for its automatic winding mechanism.

Bien entendu, le cadran peut également être supprimé, comme dans une montre squelette, et dans ce cas la partie centrale de la masse serait située entre la platine et les aiguilles 10,11 dans cette variante.Of course, the dial can also be removed, as in a skeleton watch, and in this case the central portion of the mass would be located between the plate and the needles 10,11 in this variant.

La partie centrale (7) de la masse oscillante se déplace sur le même côté du mouvement que l'aiguillage tout en n'interférant pas avec celui-ci.The central portion (7) of the oscillating mass moves on the same side of the movement as the switch while not interfering with it.

Une montre comportant un mouvement équipé d'une masse oscillante selon la présente invention permet un remontage efficace et puissant de son barillet d'une part et d'autre part possède une esthétique totalement nouvelle, originale, ludique et attrayante.A watch comprising a movement equipped with an oscillating mass according to the present invention allows an effective and powerful winding of its barrel on the one hand and on the other hand has a totally new aesthetic, original, fun and attractive.

Comme on le voit sur les figures 2 et 3, la partie inférieure de la bague intérieure 1 du roulement à billes comporte une denture 1b en prise avec une liaison cinématique la reliant au rochet d'un barillet du mouvement d'une manière bien connue par l'homme de métier.As we see on the figures 2 and 3 , the lower part of the inner ring 1 of the ball bearing has a toothing 1b engaged with a kinematic connection connecting it to the ratchet of a movement barrel in a manner well known to those skilled in the art.
