Description

La présente invention concerne un mécanisme à tourbillon destiné à améliorer la précision de marche de l'organe régulateur et plus spécifiquement à améliorer la construction mécanique d'un tel mécanisme conduisant à une plus grande précision de positionnement des pièces formant ces mécanismes.The present invention relates to a vortex mechanism for improve the operating precision of the regulating organ and more specifically to improve the mechanical construction of such a mechanism leading to more high positioning accuracy of the parts forming these mechanisms.

Des mécanismes à tourbillon sont connus depuis le premier dispositif de ce genre imaginé par A.-L. Breguet en 1801 dans une variété de formes d'exécution.Whirlpool mechanisms have been known since the first device of this genre imagined by A.-L. Breguet in 1801 in a variety of embodiments.

Un tel mécanisme comprend une cage montée d'une manière pivotante dans le boítier de la pièce d'horlogerie concernée, cette cage portant tous les organes de l'échappement et l'organe régulateur. Dus à la complexité et au but susmentionné d'un tel mécanisme, tous les éléments d'un mécanisme à tourbillon doivent être entre autres positionnés de façon aussi précise que possible.Such a mechanism includes a cage pivotally mounted in the case of the timepiece concerned, this cage carrying all the exhaust organs and the regulating organ. Due to complexity and purpose aforementioned of such a mechanism, all the elements of a vortex mechanism Among other things, they should be positioned as precisely as possible.

Malgré un grand nombre d'exécutions différentes de ces mécanismes, l'agencement et/ou l'arrangement de plusieurs pièces dans les mécanismes à tourbillon conventionnels n'est pas encore optimal.Despite a large number of different executions of these mechanisms, the arrangement and / or arrangement of several parts in the mechanisms to conventional vortex is not yet optimal.

Ceci concerne d'abord la cage qui est composée normalement d'une partie supérieure et d'une partie inférieure qui étaient jusqu'à maintenant fixées l'une à l'autre à l'aide des piliers vissés. Cette solution habituelle pose des problèmes au niveau de la concentricité de tous les éléments de la cage par rapport à l'axe du balancier et aussi au niveau de la rigidité et du poids de la cage ainsi que pour son assemblage.This concerns first the cage which is normally composed of a part upper and lower part which were hitherto fixed one to the other using the screwed pillars. This usual solution poses problems for level of the concentricity of all the elements of the cage relative to the axis of the pendulum and also in terms of the rigidity and weight of the cage as well as for its assembly.

Pareillement, l'ancre et la roue d'échappement sont sujettes à des améliorations envisageables concernant entre autres leur positionnement l'une par rapport à l'autre à l'aide de la cage, voire sur un élément fixé à cette dernière, ceci en vue d'augmenter la précision de ce positionnement et du guidage des éléments lors du fonctionnement du mécanisme.Similarly, the anchor and the escape wheel are subject to possible improvements concerning among other things their positioning, one by relative to the other using the cage, or even on an element fixed to the latter, this in order to increase the precision of this positioning and of the guidance of the elements during the operation of the mechanism.

Le but de la présente invention est de remédier aux inconvénients précités et de permettre la réalisation d'un mécanisme à tourbillon simple avec un nombre de pièces et un poids réduits assurant en même temps la concentricité des éléments et la rigidité de la cage ainsi que de garantir le positionnement facile et précis de l'ancre et de la roue d'échappement sur la cage assurant simultanément un meilleur guidage de ceux-ci.The object of the present invention is to remedy the aforementioned drawbacks and allow the realization of a simple tourbillon mechanism with a number of parts and a reduced weight ensuring at the same time the concentricity of elements and stiffness of the cage as well as guaranteeing easy positioning and precise anchor and escape wheel on the cage ensuring simultaneously better guidance of these.

L'objet de la présente invention est de ce fait un mécanisme à tourbillon qui se distingue par les caractéristiques énoncées aux revendications 1 et 6 et/ou aux revendications dépendantes.The object of the present invention is therefore a vortex mechanism which is distinguished by the characteristics set out in claims 1 and 6 and / or dependent claims.

Le dessin illustre schématiquement et à titre d'exemple une forme d'exécution d'un mécanisme à tourbillon selon la présente invention.The drawing illustrates schematically and by way of example a shape of execution of a tourbillon mechanism according to the present invention.

La figure 1 montre la cage du mécanisme à tourbillon et les éléments montés sur la cage, spécifiquement un pont monolithique pour le montage de l'ancre et de la roue d'échappement.Figure 1 shows the cage of the vortex mechanism and the elements mounted on the cage, specifically a monolithic bridge for mounting the anchor and the escape wheel.

Les figures 2a et 2b montrent des coupes de la cage selon la ligne A-A de la figure 1, une fois en plan et une fois en perspective.Figures 2a and 2b show sections of the cage along line A-A of Figure 1, once in plan and once in perspective.

La figure 3 est une vue en perspective du pont monolithique destiné au positionnement de la roue d'échappement et de l'ancre.Figure 3 is a perspective view of the monolithic bridge for positioning of the escape wheel and the anchor.

Dans la suite, une forme d'exécution de la présente invention sera décrite en détail à l'aide des dessins susmentionnés.In the following, an embodiment of the present invention will be described in detail using the above-mentioned drawings.

Un mécanisme à tourbillon selon la présente invention comprend, comme représenté schématiquement à la figure 1, une cage 1 qui est montée d'une manière pivotante autour d'un pignon 2 dans le boítier de la pièce d'horlogerie à laquelle elle est destinée. Comme le montre la figure 2, cette cage comprend une partie supérieure 1a et une partie inférieure 1b destinées à être superposées l'une sur l'autre afin de former la cage 1. Contrairement à la solution conventionnelle d'assembler cette cage à l'aide de trois ou quatre piliers à vis disposés entre ces deux parties à une distance angulaire environ égale autour de leur périphérie, la solution envisagée par la présente invention assure l'équidistance des deux plans des parties supérieure 1a et inférieure 1b ainsi que leur concentricité et coaxialité tout le long de leur périphérie. Tout en diminuant ainsi le nombre des pièces formant la cage 1 du mécanisme et, par conséquent, en facilitant l'assemblage de la cage 1, sa rigidité est plus élevée par rapport à la solution conventionnelle connue à ce moment.A tourbillon mechanism according to the present invention comprises, as shown schematically in Figure 1, a cage 1 which is mounted in a pivoting around a pinion 2 in the case of the timepiece to which it is intended for. As shown in Figure 2, this cage includes a upper part 1a and lower part 1b intended to be superposed one on the other in order to form the cage 1. Unlike the conventional solution to assemble this cage using three or four screw pillars arranged between these two parts at an angular distance approximately equal around their periphery, the solution envisaged by the present invention ensures the equidistance of the two planes upper parts 1a and lower 1b as well as their concentricity and coaxiality all along their periphery. While reducing the number of parts forming the cage 1 of the mechanism and, consequently, facilitating the assembly of cage 1, its rigidity is higher compared to the conventional solution known at the time.

L'assemblage de la cage, voir également le schéma de la figure 2, se fait au moyen des jupes cylindriques des parties supérieure 1a et inférieure 1b, c'est-à-dire des parois formant sensiblement un corps de cylindre, ces jupes cylindriques étant adaptées à être associées afin de former l'ensemble de la cage. Des éléments de positionnement 1c de formes différentes peuvent assurer l'orientation et le positionnement désiré des parties supérieure 1a et inférieure 1b l'une sur l'autre. De préférence, ces éléments de positionnement 1c sont réalisés en équipant les jupes cylindriques de la partie supérieure 1a et inférieure 1b à leur extrémité orientée au centre de la cage 1 d'un rétrécissement radial, l'une à l'intérieur et l'autre à l'extérieur comme aux figures 2a et 2b, de façon à ce que les deux parties 1a et 1b s'emboítent et soient positionnées précisément l'une par rapport à l'autre et par rapport à l'axe du balancier. Ces deux parties 1a et 1b sont donc guidées en ce qui concerne leur positionnement par leurs jupes cylindriques et plus spécifiquement par leurs éléments de positionnement 1c ou formations d'emboítement, c'est-à-dire par des éléments concentriques à l'axe de la cage 1, afin que l'axe de la cage 1 soit parfaitement aligné sur le même axe que le balancier, définissant ainsi une concentricité optimale.The assembly of the cage, see also the diagram in Figure 2, is done by means of the cylindrical skirts of the upper 1a and lower 1b parts, that is to say walls substantially forming a cylinder body, these skirts cylindrical being adapted to be combined in order to form the entire cage. Positioning elements 1c of different shapes can ensure the desired orientation and positioning of the upper 1a and lower 1b parts one over the other. Preferably, these positioning elements 1c are produced by fitting the cylindrical skirts of the upper 1a and lower 1b to their end oriented in the center of the cage 1 with a radial narrowing, one at inside and the other outside as in Figures 2a and 2b, so that the two parts 1a and 1b fit together and are positioned precisely one by relative to each other and relative to the pendulum axis. These two parts 1a and 1b are therefore guided with regard to their positioning by their cylindrical skirts and more specifically by their positioning elements 1c or training interlocking, that is to say by elements concentric with the axis of the cage 1, so that the axis of cage 1 is perfectly aligned on the same axis as the pendulum, thus defining an optimal concentricity.

Enfin, la fixation de ces pièces peut se faire au moyen de différentes solutions, par exemple à l'aide de vis 1d placées dans des orifices prévus à cet effet dans les jupes cylindriques des parties supérieure 1a et inférieure 1b ; les jupes peuvent être localement plus épaisses aux endroits munis de ces orifices destinés à recevoir les vis 1d, ces jupes rejoignant de préférence les ponts de la cage venus également d'une pièce de fabrication avec lesdites jupes portant les autres éléments qui ne sont pas importants dans le cadre de la présente invention et ne seront de ce fait pas décrits en détail ici. Finally, the fixing of these parts can be done by means of different solutions, for example using 1d screws placed in holes provided for this effect in the cylindrical skirts of the upper 1a and lower 1b parts; the skirts may be locally thicker in places provided with these orifices intended to receive the 1d screws, these skirts preferably joining the bridges of the cage also come from a manufacturing part with said skirts carrying the other elements which are not important in the context of the present invention and will therefore not be described in detail here.

Les deux parties 1a, 1b de la cage sont fabriquées en un alliage d'aluminium traité par une oxydation anodique. A côté de la rigidité de ce matériau et des avantages en découlant mentionnés plus haut, ceci rend la cage également plus légère qu'une cage assortie de manière conventionnelle avec les trois piliers habituels.The two parts 1a, 1b of the cage are made of an alloy aluminum treated by anodic oxidation. Besides the rigidity of this material and the resulting benefits mentioned above, this also makes the cage lighter than a cage conventionally matched with the three pillars usual.

Ainsi, la présente invention garantit plusieurs avantages, voire un nombre des pièces réduit et un assemblage facile de la cage 1, un poids réduit, une rigidité élevée et surtout une précision améliorée au niveau de la concentricité des pièces formant la cage 1 et des éléments montés sur ces derniers par rapport à l'axe du balancier.Thus, the present invention guarantees several advantages, even a number reduced parts and easy assembly of the cage 1, a reduced weight, a high rigidity and above all improved precision in the concentricity of the parts forming the cage 1 and elements mounted thereon relative to the pendulum axis.

De plus, un mécanisme de tourbillon selon la présente invention comprend une cage 1 associée à un pont monolithique 7, c'est-à-dire en une seule pièce, qui assure le positionnement d'une roue d'échappement 3 et simultanément d'une ancre 5 et qui est illustré schématiquement à la figure 3. Le pont monolithique 7 présente de préférence sensiblement la forme d'un segment circulaire qui contourne les éléments au centre de la cage et qui est équipé des orifices et logements. Ce pont monolithique 7 est concentrique à l'axe de la cage 1 du tourbillon.In addition, a tourbillon mechanism according to the present invention comprises a cage 1 associated with a monolithic bridge 7, that is to say in one piece, which ensures the positioning of an escape wheel 3 and simultaneously of a anchor 5 and which is illustrated diagrammatically in FIG. 3. The monolithic bridge 7 preferably has substantially the shape of a circular segment which bypasses the elements in the center of the cage and which is fitted with holes and housing. This monolithic bridge 7 is concentric with the axis of the cage 1 of the whirlwind.

La roue d'échappement 3 est montée de manière pivotante autour d'un pignon de la roue d'échappement 4, l'ancre 5 est montée autour d'une tige d'ancre 6. Ces deux fournitures 4 et 6 sont toutes les deux montées, dans le cas représenté à la figure 1 à leur extrémité supérieure, sur le pont monolithique 7 dans deux paliers 7b et 7c recevant les pivots de l'ancre et de la roue d'échappement de façon à ce que l'ancre 5 puisse travailler avec la roue d'échappement pour le fonctionnement normal d'un mécanisme à tourbillon qui ne sera pas décrit plus en détail par la suite, car ce fonctionnement n'est pas essentiel pour l'invention. Comme le montre la figure 3, ce pont monolithique 7 peut comprendre un palier de pignon 7b élaboré pour héberger le pivot du pignon d'échappement qui est destiné à engrener avec encore d'autres rouages. Le fait de monter l'ancre 5 et la roue d'échappement 3 sur un pont monolithique améliore la précision de leur positionnement réciproque et de leur guidage. De plus, un tel système rend le mécanisme de tourbillon et sa cage 1 équipée de ce pont monolithique 7 plus compact.The escape wheel 3 is pivotally mounted around a pinion of the escape wheel 4, the anchor 5 is mounted around an anchor rod 6. These two supplies 4 and 6 are both mounted, in the case shown in Figure 1 at their upper end, on the monolithic bridge 7 in two bearings 7b and 7c receiving the pivots of the anchor and the wheel exhaust so that the anchor 5 can work with the wheel exhaust for normal operation of a vortex mechanism which does not will not be described in more detail below, since this operation is not essential for the invention. As shown in Figure 3, this monolithic bridge 7 may include a pinion bearing 7b designed to accommodate the pinion of the pinion which is intended to mesh with yet other cogs. The fact mounting the anchor 5 and the escape wheel 3 on a monolithic bridge improves the precision of their reciprocal positioning and their guidance. In addition, such system makes the tourbillon mechanism and its cage 1 fitted with this bridge monolithic 7 more compact.

La fixation du pont monolithique 7 à la cage 1 se fait également de préférence à l'aide de vis logées dans des orifices 7a prévus à cet effet aux deux extrémités du pont monolithique 7 et de filetages correspondants pratiqués dans des tubes de guidage eux-mêmes chassés dans les bras de la partie supérieure de la cage 1.The attachment of the monolithic bridge 7 to the cage 1 is also done by preferably using screws housed in holes 7a provided for this purpose in both ends of the monolithic bridge 7 and corresponding threads practiced in guide tubes themselves driven into the upper arms of cage 1.

L'ensemble de la cage 1 associé au pont monolithique 7 permet d'assurer une précision améliorée par rapport à l'état de la technique en ce qui concerne la concentricité de l'axe de la cage 1 et du balancier ainsi que le positionnement de la roue d'échappement 3 et l'ancre 5 et contribue ainsi à améliorer la précision de marche de l'organe régulateur.The entire cage 1 associated with the monolithic bridge 7 ensures improved accuracy over the state of the art with respect to the concentricity of the axis of the cage 1 and the pendulum as well as the positioning of the escape wheel 3 and the anchor 5 and thus contributes to improving the precision of functioning of the regulatory body.

Dans une variante, il est évident que le pont monolithique 7 pourrait être utilisé avec une cage de tourbillon conventionnelle à piliers vissés pour la fixation des cages supérieure et inférieure.In a variant, it is obvious that the monolithic bridge 7 could be used with a conventional swirl cage with screwed pillars for fixing upper and lower cages.

De même, la cage 1 à jupes cylindriques s'emboítant peut être utilisée avec deux ponts, l'un pour le tourillonnement de l'ancre et l'autre pour celui de la roue d'échappement.Similarly, the cage 1 with interlocking cylindrical skirts can be used with two bridges, one for the pivoting of the anchor and the other for that of the wheel exhaust.
