Description

Arrière-plan de l'inventionBackground of the invention

La présente invention concerne un mouvement horloger à tourbillon muni d'un dispositif de protection contre les chocs. La présente invention concerne en outre une montre équipée d'un tel mouvement horloger.The present invention relates to a tourmillon watch movement provided with a device for protection against shocks. The present invention further relates to a watch equipped with such a watch movement.

Les mouvements à tourbillon sont des dispositifs mécaniques destinés à améliorer la précision des montres mécaniques en contrebalançant les perturbations de l'isochronisme du balancier dues à la gravité terrestre. Pour ce faire l'organe réglant comprenant le balancier et l'échappement sont montés dans une cage qui est mise en rotation généralement à raison d'un tour complet en une minuteThe tourbillon movements are mechanical devices designed to improve the accuracy of mechanical watches by counterbalancing the disturbances of balance isochronism due to Earth's gravity. To do this the regulating member comprising the balance and the exhaust are mounted in a cage which is rotated generally at a rate of one complete revolution in one minute

La cage du tourbillon est généralement, maintenue en place entre deux pivots prévus respectivement dans la platine du mouvement et dans un pont du mouvement. Alternativement la cage peut être pivotée dans un palier à billes, ce qui lui permet d'être mieux visible du côté cadran.The tourbillon cage is generally held in place between two pivots respectively provided in the plate of the movement and in a bridge of the movement. Alternatively the cage can be rotated in a ball bearing, which allows it to be better visible on the dial side.

Dans le cas d'un pivotement entre la platine et un pont, la cage est généralement formée d'un pont inférieur sur lequel sont fixés des piliers portant un pont supérieur et ces ponts inférieur et supérieur portent des pivots qui tournent respectivement dans une pierre supportée par la platine et une pierre supportée par le pont du mouvement.In the case of pivoting between the plate and a bridge, the cage is generally formed of a lower bridge on which are fixed pillars carrying an upper bridge and these lower and upper bridges have pivots which rotate respectively in a supported stone by the platinum and a stone supported by the bridge of the movement.

Selon les modes de réalisation, le pont du mouvement peut être formé soit d'une poutre en porte à faux, soit d'une poutre encastrés à ses deux extrémités.According to the embodiments, the bridge of the movement can be formed either of a cantilevered beam, or of a beam recessed at both ends.

Un inconvénient de ces mécanismes de tourbillon est leur grande sensibilité aux chocs ; En effet, il est difficile de faire résister ce type de mécanisme à des accélérations de plus de 3500G sans détérioration alors que les standard d'homologation NIHS requièrent une résistance à des accélérations de 5000 G.A disadvantage of these vortex mechanisms is their high sensitivity to shocks; Indeed, it is difficult to resist this type of mechanism at accelerations of more than 3500G without deterioration then that NIHS approval standards require resistance to 5000 G accelerations.

En effet, en cas de chocs importants appliqués à la montre le poids de la cage du tourbillon est tel que le pont du mouvement fléchit ou se déforme de sorte que la cage se déplace le long de son axe de rotation et provoque la sortie du pivot inférieur de la cage du logement de sa pierre. Selon l'intensité du choc et donc l'amplitude du déplacement de la cage, le pivot ne revient pas dans son logement ce qui provoque un arrêt brutal de la rotation de la cage et donc du mouvement. Après un tel choc l'intervention d'un horloger pour la remise en marche de la montre est donc nécessaire. A noter que dans certains cas le déplacement de la cage peut être tel que le pignon d'échappement se désengage de la denture de seconde fixe, ce qui provoque un désarmage brusque du barillet qui peut conduire à la destruction de certaines pièces du mécanisme. Cet inconvénient est plus important dans le cas d'un pont supérieur formé d'une poutre en porte à faux dont la flexibilité est plus grande.Indeed, in case of major shocks applied to the watch the weight of the vortex cage is such that the bridge of the movement bends or deforms so that the cage moves along its axis of rotation and causes the output of the pivot bottom of the housing cage of his stone. Depending on the intensity of the shock and therefore the range of displacement of the cage, the pivot does not return in its housing which causes a sudden stop of the rotation of the cage and therefore the movement. After such a shock the intervention of a watchmaker for the restart of the watch is necessary. Note that in some cases the movement of the cage may be such that the exhaust pinion disengages the fixed second gear, which causes a sudden disarming of the barrel which can lead to the destruction of some parts of the mechanism. This disadvantage is more important in the case of an upper bridge formed of a cantilever beam whose flexibility is greater.

Diverses tentatives pour remédier à ce problème ont été envisagées telles que l'allègement de la cage, la rigidification du pont du mouvement, notamment en augmentant ses dimensions, ou encore l'allongement du pivot inférieur de la cage. Toutefois ces mesures n'ont pas donné de résultats satisfaisants sans alourdir la construction et ce faisant, sans affecter l'esthétisme des montres équipées de ces mécanismes.Various attempts to remedy this problem have been envisaged, such as lightening the cage, stiffening the bridge of the movement, in particular by increasing its dimensions, or even lengthening the lower pivot of the cage. However these measures have not given satisfactory results without weighing down the construction and in doing so, without affecting the aesthetics of watches equipped with these mechanisms.

La présente invention a pour but de remédier aux inconvénients susmentionnés ainsi qu'à d'autres encore en fournissant un mouvement horloger à tourbillon qui présente une résistance aux chocs améliorés par rapport aux tourbillons de l'art antérieur.It is an object of the present invention to overcome the above-mentioned and other disadvantages by providing a vortex clock movement which has improved impact resistance over vortices of the prior art.

L'invention a également pour but de fournir un tel mouvement horloger qui soit de conception simple, économique et facile à mettre en oeuvre.The invention also aims to provide such a watch movement which is simple in design, economical and easy to implement.

L'invention a également pour but de fournir un tel mouvement horloger sans affecter son esthétisme habituel.The invention also aims to provide such a watch movement without affecting its usual aesthetics.

Résumé de l'inventionSummary of the invention

A cet effet l'invention a pour objet un mouvement horloger comportant un tourbillon ayant une cage rotative portant un balancier-spiral et un échappement, ladite cage comprenant un pivot supérieur et un pivot inférieur porté respectivement par un pont supérieur et un pont inférieur de la cage, ladite cage étant pivotée entre une platine dudit mouvement horloger et un pont dudit mouvement, le mouvement étant caractérisé en ce qu'il comporte en outre un organe de butée agencé pour limiter l'ébat axial de la cage.To this end, the subject of the invention is a watch movement comprising a vortex having a rotary cage carrying a balance-spring and an escapement, said cage comprising an upper pivot and a lower pivot carried respectively by an upper bridge and a lower bridge of the cage, said cage being pivoted between a plate of said watch movement and a bridge of said movement, the movement being characterized in that it further comprises a stop member arranged to limit the axial frust of the cage.

Grâce à ces caractéristiques, la tenue aux chocs du mouvement horloger peut être ainsi garantie dans la mesure où le déplacement axial de la cage maximum est prédéfini pour qu'une sortie des pivots de la cage du logement de leur palier respectif soit impossible.Thanks to these characteristics, the shock resistance of the watch movement can thus be guaranteed insofar as the axial displacement of the maximum cage is predefined so that an exit of the pins of the cage of the housing of their respective bearing is impossible.

Selon un mode de réalisation avantageux, l'organe de butée est porté par la platine du mouvement et coopère avec le pont inférieur de ladite cage.According to an advantageous embodiment, the stop member is carried by the platen of the movement and cooperates with the lower bridge of said cage.

Selon une caractéristique de ce mode de réalisation de l'invention, une douille, qui porte le pivot inférieur, s'étend à partir de la partie centrale du pont inférieur de la cage, cette douille portant également un épaulement, l'organe de butée coopérant avec l'épaulement pour limiter l'ébat axial de la cage.According to a feature of this embodiment of the invention, a bushing, which carries the lower pivot, extends from the central part of the lower deck of the cage, this bushing also bearing a shoulder, the stop member cooperating with the shoulder to limit the axial fretting of the cage.

Selon une autre caractéristique de l'invention, le pivot inférieur est logé dans un palier inférieur porté par la platine, et en l'absence de choc, la distance entre l'organe de butée et l'épaulement est inférieur à la longueur d'engagement du pivot inférieur dans le palier.According to another characteristic of the invention, the lower pivot is housed in a lower bearing carried by the plate, and in the absence of impact, the distance between the abutment member and the shoulder is less than the length of lower pivot engagement in the bearing.

Selon une caractéristique préférée, l'organe de butée est mobile entre une première position, dite de montage, dans laquelle l'organe de butée est à l'écart du chemin axial de l'épaulement pour permettre le montage de la cage sur la platine et une deuxième position dite de fonctionnement dans laquelle l'organe de butée est sur le chemin axial dudit épaulement. L'organe de butée a avantageusement la forme d'un levier articulé comprenant une première partie de commande prolongée par une deuxième partie de butée en arc de cercle, la partie de commande étant située dans une partie extrême de la deuxième partie, dans laquelle l'articulation à pivotement du levier est réalisée. Un organe de verrouillage de l'organe de butée dans la position de fonctionnement peut être également prévu pour maintenir cet organe dans cette position au cours du fonctionnement de la montre équipée du mouvement.According to a preferred characteristic, the stop member is movable between a first position, said mounting, in which the stop member is away from the axial path of the shoulder to allow mounting of the cage on the plate and a second so-called operating position in which the stop member is on the axial path of said shoulder. The stop member advantageously has the shape of a articulated lever comprising a first control portion extended by a second arcuate abutting portion, the control portion being located in an end portion of the second portion, wherein the pivoting articulation of the lever is made. A locking member of the stop member in the operating position can also be provided to maintain this member in this position during operation of the watch equipped with the movement.

Selon un autre mode de réalisation, l'organe de butée peut être porté par la cage du tourbillon et notamment par le pivot inférieur de la cage du tourbillon. Dans ce cas le pivot inférieur fera saillie hors de son palier du coté opposé à la cage et l'organe de butée pourra être formé, soit par une rondelle chassée sur la partie en saillie du pivot inférieur, soit par la tête d'une vis vissée axialement dans l'extrémité libre de la partie en saillie du pivot inférieur.According to another embodiment, the stop member may be carried by the vortex cage and in particular by the lower pivot of the vortex cage. In this case the lower pivot protrudes out of its bearing on the opposite side to the cage and the stop member can be formed either by a washer driven on the projecting portion of the lower pivot, or by the head of a screw screwed axially into the free end of the projecting portion of the lower pivot.

The watch movement 1 comprises a vortex 10 which is visible in a window of the dial or in a dial. another opaque element such as the platinum of the movement. In a conventional manner, the vortex 10 comprises a rotary cage 12 rotating about an axis 14 around which oscillates the spiral balance 16 forming the regulating member. The cage conventionally carries an exhaust E cooperating with the regulating member.

La cage 12 du tourbillon est, maintenue en place entre deux pivots inférieur 18 et supérieur 20 prévus respectivement dans la platine 22 du mouvement et dans un pont 24 du mouvement.The cage 12 of the vortex is held in place between two lower pivots 18 and upper 20 respectively provided in the plate 22 of the movement and in a bridge 24 of the movement.

Plus précisément et comme cela est visible à la figure 2, le pivot inférieur 18 de la cage 12 du tourbillon tourne dans une pierre 26 supportée par la platine 22 du mouvement par l'intermédiaire d'une pièce 28 en forme de coupelle. La coupelle 28 comprend un fond 28a prolongé par une paroi annulaire 28b qui se termine par une denture fixe 28c constituant, de manière connue, la roue dentée fixe 28c sur laquelle roule le pignon d'échappement PE du tourbillon. Dans l'exemple illustré la denture 28c s'étend vers l'extérieure de la coupelle 28.More precisely and as is visible in the figure 2 , the lower pivot 18 of the cage 12 of the tourbillon rotates in a rock 26 supported by the plate 22 of the movement via a piece 28 in the form of cup. The cup 28 comprises a bottom 28a extended by an annular wall 28b which terminates in a fixed toothing 28c constituting, in known manner, the fixed gear 28c on which rolls the exhaust pinion P E of the vortex. In the example illustrated, the toothing 28c extends towards the outside of the cup 28.

On voit également que le pivot inférieur 18 est porté par un pont inférieur 30 de la cage 12. Dans l'exemple représenté, le pont inférieur 30 comprend une plaque de base 30a qui se prolonge vers le haut de la figure 2 par des bras 30b ayant une configuration étagée. La plaque de base 30a comprend également une portion 30c en forme de douille qui s'étend vers le bas de la figure 2 à partir de sa partie centrale. La douille 30c porte le pivot 18 dans laquelle il est fixé par chassage dans cet exemple. Le pivot 18 comprend à son extrémité distale un téton 18a qui pivote dans le logement de la pierre 26. Dans sa partie médiane, le pivot 18 comprend une portion dentée 18b qui coopère avec une roue dentée du mouvement (non représentée) entrainée par le ressort de barillet de celui-ci pour mettre en rotation la cage 12 du tourbillon. Ainsi, le pont inférieur 30 via la portion de pivot 18b forment la liaison cinématique qui relie la cage 12 du tourbillon au reste du mouvement d'horlogerie. Dans sa partie proximale, le pivot 18 présente une portion 18c ayant un diamètre supérieur au diamètre de la douille 30c pour définir un épaulement 18c porté par cette dernière.We also see that the lower pivot 18 is carried by a lower bridge 30 of the cage 12. In the example shown, the lower bridge 30 comprises a base plate 30a which extends towards the top of the figure 2 by arms 30b having a stepped configuration. The base plate 30a also includes a sleeve-shaped portion 30c which extends down the figure 2 from its central part. The bushing 30c carries the pivot 18 in which it is fixed by driving in this example. The pivot 18 comprises at its distal end a pin 18a which pivots in the housing of the stone 26. In its middle part, the pivot 18 comprises a toothed portion 18b which cooperates with a toothed wheel movement (not shown) driven by the spring barrel thereof to rotate the cage 12 of the tourbillon. Thus, the lower bridge 30 via the pivot portion 18b form the kinematic connection which connects the cage 12 of the tourbillon to the rest of the watch movement. In its proximal portion, the pivot 18 has a portion 18c having a diameter greater than the diameter of the sleeve 30c to define a shoulder 18c carried by the latter.

Il va de soi que selon une variante, le pont inférieur 30 pourrait être réalisé d'une seule pièce avec le pivot 18.It goes without saying that according to one variant, the lower bridge 30 could be made in one piece with the pivot 18.

La plaque de base 30a porte en outre de manière classique le pont d'échappement P et les paliers du mobile d'échappement ME (figure 2) et de l'ancre A.The base plate 30a additionally carries, in a conventional manner, the exhaust bridge P and the bearings of the escape wheel M E ( figure 2 ) and anchor A.

De même, le pivot supérieur 20 de la cage 12 tourne dans une pierre 32 supportée par le pont de tourbillon 24 qui comprend une poutre en porte à faux visible aux figures 1 et 2. Cette poutre est fixée sur la platine 22 du mouvement au moyen de vis. Le pivot supérieur 20 est porté par un pont supérieur 34 de la cage 12. Dans l'exemple représenté, le pont supérieur 34 comprend une plaque de base 34a qui porte le pivot 20. La plaque de base 34a se prolonge vers le bas de la figure 2 par des bras 34b ayant également une configuration étagée en regard des bras 30b du pont inférieur 30 de la cage 12. Les ponts inférieur 30 et supérieur 34 de la cage sont fixés ensemble par l'intermédiaire de leurs bras respectifs.Similarly, the upper pivot 20 of the cage 12 rotates in a stone 32 supported by the vortex bridge 24 which comprises a cantilever beam visible to the figures 1 and 2 . This beam is fixed on the plate 22 of the movement by means of screws. The upper pivot 20 is worn by an upper bridge 34 of the cage 12. In the example shown, the upper bridge 34 comprises a base plate 34a which carries the pivot 20. The base plate 34a extends towards the bottom of the figure 2 by arms 34b also having a stepped configuration opposite the arms 30b of the lower bridge 30 of the cage 12. The lower bridges 30 and upper 34 of the cage are fixed together through their respective arms.

Selon l'invention, le mouvement horloger à tourbillon 1 comporte en outre un organe de butée 36 agencé pour limiter l'ébat axial de la cage 12 du tourbillon, notamment en cas de chocs que peut subir la montre par exemple lors d'une chute.According to the invention, the vortex tourmillon movement 1 further comprises a stop member 36 arranged to limit the axial fretting of the vortex cage 12, in particular in the event of shocks that may be experienced by the watch, for example during a fall. .

Par ébat axial, on comprendra le déplacement selon l'axe de rotation 14 de la cage 12 du tourbillon qui peut notamment résulter du fléchissement du pont de tourbillon 24 lors d'un choc. Pour fixer les idées et compte tenu des différentes tolérances de fabrication et de montage des différents éléments entre eux, un tel ébat peut atteindre des valeurs de l'ordre de 0,40 mm à 0,50 mm en cas de chocs en l'absence de moyens de limitation tels que l'organe de butée 36 prévu par l'insertion.By axial fretting, it will be understood the displacement along the axis of rotation 14 of the cage 12 of the vortex which may result in particular from the deflection of the vortex bridge 24 during an impact. To fix the ideas and taking into account the different tolerances of manufacture and assembly of the different elements between them, such a frost can reach values of the order of 0.40 mm to 0.50 mm in case of shocks in the absence limiting means such as the stop member 36 provided by the insertion.

Dans le mode de réalisation illustré aux figures 1 à 5 l'organe de butée 36 est porté par la platine 22 du mouvement et coopère avec le pont inférieur 30 de la cage 12.In the embodiment illustrated in Figures 1 to 5 the stop member 36 is carried by the plate 22 of the movement and cooperates with the lower bridge 30 of the cage 12.

Plus précisément, l'organe de butée 36 coopère avec l'épaulement 18c porté par le pont inférieur 30. En l'absence de choc, la distance D (figure 5) entre l'organe de butée 36 et l'épaulement 18c est inférieure à la longueur d'engagement L (figure 5) du téton 18a du pivot inférieur 18 dans le logement du palier 26, formé dans l'exemple par un pierre. Ainsi, lorsque la montre équipée du mouvement horloger à tourbillon selon l'invention subit un choc violent, le déplacement de la cage 12 provoqué par ce choc ne peut dépasser la valeur D de sorte qu'en toute circonstance le téton 18a ne pourra pas sortir de son logement. Typiquement la distance D est de l'ordre de 0,20 mm tandis que la longueur L est de l'ordre de 0,35mm.More specifically, the abutment member 36 cooperates with the shoulder 18c carried by the lower bridge 30. In the absence of shock, the distance D ( figure 5 ) between the abutment member 36 and the shoulder 18c is less than the engagement length L ( figure 5 ) of the stud 18a of the lower pivot 18 in the housing of the bearing 26, formed in the example by a stone. Thus, when the watch equipped with the tourmillon clock movement according to the invention is subjected to a violent shock, the displacement of the cage 12 caused by this shock can not exceed the value D so that in any circumstance the stud 18a can not get out of his dwelling. Typically the distance D is of the order of 0.20 mm while the length L is of the order of 0.35 mm.

Dans le mode de réalisation illustré, l'organe de butée 36 est monté mobile entre une première position dite de montage (figures 4 ;7) dans laquelle l'organe de butée 36 est à l'écart du chemin axial de l'épaulement 18c pour permettre le montage de la cage 12 sur la platine 22 et une deuxième position dite de fonctionnement (figures 3 ;6) dans laquelle l'organe de butée 36 est sur le chemin axial de l'épaulement 18c. L'organe de butée 36 est articulé sur le fond 28a de la coupelle 28, typiquement au moyen d'une vis V1 traversant le fond 28a de la coupelle 28 et vissée sur la platine 24.In the illustrated embodiment, the abutment member 36 is movably mounted between a first mounting position ( figures 4 ; 7 ) in which the abutment member 36 is away from the axial path of the shoulder 18c to allow mounting of the cage 12 on the plate 22 and a second operating position ( figures 3 ; 6 ) in which the abutment member 36 is in the axial path of the shoulder 18c. The abutment member 36 is articulated on the bottom 28a of the cup 28, typically by means of a screw V1 passing through the bottom 28a of the cup 28 and screwed onto the plate 24.

On notera à ce propos que le montage de cet organe de butée dans la coupelle de la seconde fixe du mécanisme de tourbillon est particulièrement avantageux dans la mesure où il vient occuper un volume présent dans ce mécanisme et jusqu'à maintenant non utilisé.It should be noted in this connection that the mounting of this abutment member in the cup of the second fixed tourbillon mechanism is particularly advantageous insofar as it comes to occupy a volume present in this mechanism and until now unused.

L'organe de butée 36 a la forme d'un levier articulé comprenant une première partie de commande 36a présentant la forme d'un bras rectiligne prolongé par une deuxième partie de butée 36b présentant la forme d'un bloc massif arc de cercle. Le bras de commande 36a s'étend à partir d'une partie extrême du bloc 36b, dans laquelle l'articulation à pivotement du levier est réalisée en 36c. Le bloc massif 36b présente une épaisseur sensiblement supérieure à celle du bras 36a. On voit également que le bord périphérique intérieur supérieur du bloc massif 36b présente une saillie 36d définissant une surface de butée qui se trouve à l'aplomb de l'épaulement 18 lorsque l'organe de butée se trouve en position de fonctionnement. Le bloc massif 36b présente par ailleurs dans son bord périphérique intérieur inférieur une rainure 36e dont le profil présente une forme complémentaire à celle d'une vis V2 qui sert à la fois au guidage en pivotement et au blocage axial de l'organe de butée 36 notamment en cas de chocs.The stop member 36 has the shape of an articulated lever comprising a first control portion 36a having the shape of a rectilinear arm extended by a second abutment portion 36b having the shape of a solid block arcuate circle. The control arm 36a extends from an end portion of the block 36b, wherein the lever pivot is formed at 36c. The solid block 36b has a thickness substantially greater than that of the arm 36a. It can also be seen that the upper inner peripheral edge of the solid block 36b has a projection 36d defining an abutment surface which is in line with the shoulder 18 when the stop member is in the operating position. The solid block 36b further has in its lower inner peripheral edge a groove 36e whose profile has a shape complementary to that of a screw V2 which serves both to guide pivotally and axially lock the stop member 36 especially in case of shocks.

Pour maintenir l'organe de butée 36 dans la position de fonctionnement, le mouvement 1 comprend en outre un organe de verrouillage 38 qui est formé d'une goupille chassée dans la platine du mouvement. Cette goupille 38 est destinée à se loger dans une ouverture oblongue 40 prévue dans le bras de commande 36a de l'organe de butée 36 en position de fonctionnement. On notera à ce propos que la paroi annulaire 28b de la coupelle 28 comprend une ouverture oblongue 42 à travers laquelle s'étend le bras de commande 36a de l'organe de butée 36 On notera à ce propos que la coupelle comprend également une ouverture O pour le passage d'une roue d'entrainement (non représentée) de la cage 12 vers le pignon 18b.To maintain the abutment member 36 in the operating position, the movement 1 further comprises a locking member 38 which is formed of a pin driven into the platen of the movement. This pin 38 is intended to be housed in an oblong opening 40 provided in the control arm 36a of the stop member 36 in the operating position. It should be noted in this connection that the wall Annular 28b of the cup 28 comprises an oblong opening 42 through which extends the control arm 36a of the abutment member 36 It should be noted in this connection that the cup also comprises an opening O for the passage of a wheel. drive (not shown) of the cage 12 to the pinion 18b.

La réalisation d'un organe de butée mobile entre les deux positions susmentionnées permet de faciliter le montage du tourbillon. En effet, après le montage de la coupelle 28 muni du palier 26 sur la platine 22, l'organe butée 36 est monté dans le fond de la coupelle puis pivoté dans sa position de montage dans laquelle la cage 12 peut être aisément montée dans son pivotement. Une fois la cage du tourbillon mise en place, il ne reste plus qu'à faire pivoter l'organe de butée 36 et verrouiller ce dernier dans sa position de fonctionnement dans laquelle le rebord 36c du bloc de l'organe 36 vient se placer à l'aplomb de l'épaulement 18c du pont inférieur de la cage 30 On limite ainsi en toutes circonstances l'ébat axial de la cage 12 à la distance D séparant l'épaulement 18c du rebord 36c.The realization of an abutment member movable between the two aforementioned positions facilitates the mounting of the vortex. Indeed, after the mounting of the cup 28 provided with the bearing 26 on the plate 22, the stop member 36 is mounted in the bottom of the cup and then pivoted into its mounting position in which the cage 12 can be easily mounted in its seat. pivoting. Once the vortex cage is in place, it remains only to rotate the abutment member 36 and lock the latter in its operating position in which the flange 36c of the block of the member 36 is placed at the plumb with the shoulder 18c of the lower bridge of the cage 30 is thus limited in all circumstances the axial fretting of the cage 12 at the distance D between the shoulder 18c of the flange 36c.

A la figure 8 est représenté partiellement un mouvement horloger à tourbillon selon un deuxième mode de réalisation de l'invention dans lequel les éléments identiques à ceux décrits en liaison avec les figures 1 à 7 sont désignés par les mêmes références numériques.To the figure 8 partially shown is a tourmillon watch movement according to a second embodiment of the invention in which the elements identical to those described in connection with the Figures 1 to 7 are designated by the same reference numerals.

Ce deuxième mode de réalisation se distingue de celui décrit en liaison avec les figures 1 à 7 en ce que l'organe de butée 36 n'est plus porté par la platine 22 mais est porté par la cage 12 du tourbillon. En particulier l'organe de butée 36 est porté par le téton 18a pivot inférieur 18 de la cage du tourbillon. Pour ce faire, la longueur du téton 18a du pivot inférieur est adaptée pour faire saillie hors du palier 26 du coté opposé à la cage 12 et l'organe de butée est formé par une rondelle chassée sur la partie en saillie du téton du pivot inférieur. Dans une variante la partie en saillie du téton 18a peut comprendre une rainure annulaire et la rondelle peut prendre la forme d'un anneau élastique 36.This second embodiment differs from that described in connection with the Figures 1 to 7 in that the abutment member 36 is no longer carried by the plate 22 but is carried by the cage 12 of the vortex. In particular the abutment member 36 is carried by the stud 18a lower pivot 18 of the tourbillon cage. To do this, the length of the stud 18a of the lower pivot is adapted to protrude from the bearing 26 on the opposite side to the cage 12 and the stop member is formed by a washer driven on the projecting portion of the nipple of the lower pivot . In a variant, the protruding portion of the stud 18a may comprise an annular groove and the washer may take the form of an elastic ring 36.

A la figure 9 est représentée une autre variante de réalisation du deuxième mode de réalisation de la figure 9 dans lequel l'organe de butée est formé par la tête d'une vis vissée axialement dans l'extrémité libre de la partie en saillie du pivot inférieur.To the figure 9 another alternative embodiment of the second embodiment of the figure 9 in which the stop member is formed by the head of a screw screwed axially into the free end of the projecting portion of the lower pivot.

Il va de soi que la présente invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées.It goes without saying that the present invention is not limited to the embodiments which have 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 invention as defined by the appended claims.

En particulier, il peut être envisagé de monter l'organe de butée du premier mode de réalisation non pas à pivotement mais à coulissement sur la platine du mouvement ou dans la coupelle. Dans le cadre du premier mode, de réalisation décrit ci-dessus, on peut également prévoir deux organes de butée, de préférence disposés l'un en face de l'autre. Dans une autre variante du premier mode de réalisation on peut prévoir que l'organe de butée soit fixe. Dans ce cas par exemple, il sera vissé dans le fond de la coupelle en position de fonctionnement depuis le dessous de la coupelle après montage de la cage. Enfin selon encore une autre variante on pourra prévoir de monter l'organe de butée en dehors de la coupelle à distance du pivot inférieur, bien qu'il soit avantageux de limiter l'ébat à un endroit le plus proche possible de ce pivot.In particular, it may be envisaged to mount the abutment member of the first embodiment not to pivot but to slide on the movement plate or in the cup. In the context of the first embodiment, described above, it is also possible to provide two abutment members, preferably arranged opposite one another. In another variant of the first embodiment, it is possible for the stop member to be fixed. In this case for example, it will be screwed into the bottom of the cup in the operating position from below the cup after mounting the cage. Finally according to yet another variant may be provided to mount the stop member outside the cup distance from the lower pivot, although it is advantageous to limit the frolicking at a position as close as possible to this pivot.

Le mouvement horloger à tourbillon qui vient d'être décrit l'a été dans le cadre d'une application à une montre-bracelet, mais il est bien évident que cette application n'est aucunement limitative et que le mouvement horloger selon l'invention peut être utilisé pour équiper d'autres types de pièces d'horlogerie telles que notamment des montres de poche.The vortex tourbillon movement that has just been described was in the context of an application to a wristwatch, but it is obvious that this application is in no way limiting and the watch movement according to the invention can be used to equip other types of timepieces such as including pocket watches.
