Description

La présente invention concerne un dispositif pour une pièce d'horlogerie comprenant un organe mobile pouvant prendre plusieurs positions déterminées sous l'action d'un organe de commande. Plus particulièrement, la présente invention concerne un dispositif d'embrayage, pour un chronographe notamment.The present invention relates to a device for a timepiece comprising a movable member that can take several determined positions under the action of a control member. More particularly, the present invention relates to a clutch device, especially for a chronograph.

Dans un chronographe, un dispositif d'embrayage permet de transmettre le mouvement d'un mobile du rouage de finissage à la roue de chronographe qui porte l'aiguille de chronographe. Le dispositif d'embrayage comprend une roue d'embrayage pouvant occuper une position embrayée, correspondant à la position de marche du chronographe, où la roue de chronographe est entraînée par un mobile du rouage de finissage via la roue d'embrayage, et une position débrayée, correspondant à la position d'arrêt du chronographe, où la roue de chronographe n'est pas entraînée par un mobile du rouage de finissage via la roue d'embrayage.In a chronograph, a clutch device makes it possible to transmit the movement of a moving body from the finishing train to the chronograph wheel carrying the chronograph hand. The clutch device comprises a clutch wheel that can occupy an engaged position, corresponding to the chronograph running position, where the chronograph wheel is driven by a mobile of the work train via the clutch wheel, and a position disengaged, corresponding to the stop position of the chronograph, where the chronograph wheel is not driven by a mobile of the work train via the clutch wheel.

Une bascule d'embrayage portant la roue d'embrayage coopère avec un organe de commande pour déplacer la roue d'embrayage dans ses positions embrayée et débrayée. Des sautoirs, des ressorts et des butées assurent la position des éléments du dispositif d'embrayage dans sa position embrayée ou débrayée, en particulier lorsque le chronographe est en marche.A clutch rocker carrying the clutch wheel cooperates with a control member to move the clutch wheel in its engaged and disengaged positions. Jumpers, springs and stops ensure the position of the clutch device members in its engaged or disengaged position, particularly when the chronograph is running.

Cependant, un mouvement brutal ou un choc provoquant une force supérieure à la force de rappel exercée par le ressort de commande de la bascule d'embrayage peuvent provoquer un déplacement de la bascule d'embrayage et ainsi un déplacement de la roue d'embrayage. L'entraînement de la roue de chronographe peut alors être interrompu un instant, faussant la mesure.However, a sudden movement or shock causing a force greater than the return force exerted by the control spring of the clutch rocker can cause a displacement of the clutch rocker and thus a displacement of the clutch wheel. The drive of the chronograph wheel can then be interrupted for a moment, distorting the measurement.

Le but de la présente invention est de réaliser un dispositif pour une pièce d'horlogerie comprenant un organe mobile pouvant prendre au moins deux positions déterminées et qui permette d'empêcher ledit organe mobile de quitter une de ses positions déterminées sous l'effet d'un choc. En particulier, un but de la présente invention est de réaliser un dispositif d'embrayage pour pièce d'horlogerie et notamment pour un chronographe permettant de résoudre le problème décrit ci-dessus et d'empêcher le débrayage intempestif du dispositif d'embrayage en cas de choc ou de mouvement brusque et par conséquent de garantir la mesure.The object of the present invention is to provide a device for a timepiece comprising a movable member which can take at least two predetermined positions and which makes it possible to prevent said movable member from leaving one of its determined positions under the effect of a shock. In particular, an object of the present invention is to provide a clutch device for a workpiece and especially for a chronograph to solve the problem described above and prevent clutch disengagement clutch in case of shock or sudden movement and therefore to ensure the measurement.

A cette fin, la présente invention a pour objet un dispositif pour une pièce d'horlogerie comprenant un organe mobile pouvant prendre au moins deux positions déterminées et un organe de commande coopérant avec ledit organe mobile pour définir lesdites au moins deux positions déterminées, caractérisé par le fait que le dispositif comprend en outre un organe de verrouillage solidaire de l'organe de commande et un organe intermédiaire commandé par l'organe mobile et destiné à coopérer avec l'organe de verrouillage et l'organe mobile pour empêcher ou limiter le déplacement dudit organe mobile sous l'effet d'un choc lorsque l'organe mobile est dans l'une des ces positions déterminées, évitant ainsi que ledit organe mobile ne quitte sa position déterminée.To this end, the present invention relates to a device for a timepiece comprising a movable member that can take at least two determined positions and a control member cooperating with said movable member to define said at least two predetermined positions, characterized by the fact that the device further comprises a locking member secured to the control member and an intermediate member controlled by the movable member and intended to cooperate with the locking member and the movable member to prevent or limit the displacement said movable member under the effect of a shock when the movable member is in one of these predetermined positions, thus avoiding said movable member leaves its determined position.

La présente invention a également pour objet un mécanisme de chronographe selon la revendication 12 ainsi qu'une pièce d'horlogerie selon la revendication 13.The present invention also relates to a chronograph mechanism according to claim 12 and a timepiece according to claim 13.

Dans la forme d'exécution illustrée aux figures 1 à 6, le dispositif pour une pièce d'horlogerie selon l'invention est un dispositif d'embrayage pour un chronographe.In the embodiment illustrated in Figures 1 to 6 , the device for a timepiece according to the invention is a clutch device for a chronograph.

Le dispositif d'embrayage selon la forme d'exécution illustrée de l'invention comprend une bascule d'embrayage 1 pivotée en A (par exemple sur un pont ou sur la platine du mouvement comprenant le mécanisme de chronographe) et portant une roue d'embrayage 2. La roue d'embrayage 2 est en prise en permanence avec un mobile du mouvement de base de la pièce d'horlogerie. Dans cette forme d'exécution, l'entraînement de la roue d'embrayage 2 par le mouvement de base se fait via la roue entraîneuse 3 également pivotée en A. Cette roue entraîneuse 3 est reliée de manière conventionnelle au rouage de finissage (par exemple à la roue de secondes) du mouvement.The clutch device according to the illustrated embodiment of the invention comprises a clutch rocker 1 pivoted at A (for example on a bridge or on the platen of the movement comprising the chronograph mechanism) and carrying a wheel. clutch 2. The clutch wheel 2 is permanently engaged with a mobile of the basic movement of the timepiece. In this embodiment, the driving of the clutch wheel 2 by the basic movement is via the driving wheel 3 also rotated A. This driving wheel 3 is connected in a conventional manner to the work train (for example to the seconds wheel) of the movement.

La bascule d'embrayage 1 pivote en A entre une première position illustrée à la figure 1 et dans laquelle la roue d'embrayage 2 est en position embrayée en prise avec une roue de chronographe 4 du mécanisme de chronographe et une seconde position illustrée à la figure 2, dans laquelle la roue d'embrayage 2 est en positon débrayée et n'est pas en prise avec ladite roue de chronographe 4. Ainsi, lorsque la bascule d'embrayage 1 est dans sa première position, le chronographe est en marche, tandis que lorsque la bascule d'embrayage 1 est dans sa seconde position, le chronographe n'est pas en fonction.The clutch rocker 1 pivots at A between a first position illustrated in FIG. figure 1 and wherein the clutch wheel 2 is in the engaged position engaged with a chronograph wheel 4 of the chronograph mechanism and a second position illustrated in FIG. figure 2 in which the clutch wheel 2 is in the disengaged position and is not engaged with said chronograph wheel 4. Thus, when the clutch rocker 1 is in its first position, the chronograph is in operation, while when the clutch rocker 1 is in its second position, the chronograph is not in operation.

La bascule d'embrayage 1 présente à une de ses extrémités un bec 5 (figures 3 et 4) destiné à coopérer avec un organe de commande 6 du dispositif d'embrayage pour le positionnement de ladite bascule d'embrayage 1. Dans la forme d'exécution illustrée, la came de commande est une roue à colonnes 6. De manière traditionnelle, la roue à colonnes 6 comprend une denture 6a et des colonnes 6b (figures 3 et 4) disposées perpendiculairement et de façon concentrique à la denture 6a. Un sautoir de roue à colonnes 8 coopère avec la denture 6a pour déterminer les positions stables et précises de la roue à colonnes 6. Le chronographe comprend en outre un organe de commande de chronographe (non illustré) coopérant avec la denture 6a pour l'entraînement de la roue à colonnes 6.The clutch rocker 1 has at one of its ends a spout 5 ( figures 3 and 4 ) for cooperating with a control member 6 of the clutch device for positioning said clutch rocker 1. In the illustrated embodiment, the control cam is a column wheel 6. From traditionally, the column wheel 6 comprises a toothing 6a and columns 6b ( figures 3 and 4 ) arranged perpendicularly and concentrically to the toothing 6a. Column wheel 8 cooperates with the toothing 6a to determine the stable and accurate positions of the column wheel 6. The chronograph further comprises a chronograph control member (not shown) cooperating with the teeth 6a for training of the column wheel 6.

La bascule d'embrayage 1 est soumise à l'action d'un ressort de bascule 7 qui permet de mouvoir la bascule 7 et qui tend à la maintenir au contact de la roue à colonnes 6. Dans la position embrayée représentée aux figures 1 et 4, le bec 5 de la bascule d'embrayage 1 est engagé entre deux colonnes 6b de la roue à colonnes 6.The clutch rocker 1 is subjected to the action of a rocker spring 7 which makes it possible to move the rocker 7 and which tends to keep it in contact with the column wheel 6. In the engaged position shown in FIGS. figures 1 and 4 , the spout 5 of the clutch rocker 1 is engaged between two columns 6b of the column wheel 6.

Selon un aspect essentiel de l'invention, la bascule d'embrayage 1 commande en outre un bras 9. Dans la forme d'exécution illustrée, le bras 9 est fixé sur la bascule d'embrayage 1. L'extrémité libre du bras 9 a la forme d'un premier crochet 10. Le bras 9 et le premier crochet 10 sont agencés pour coopérer avec un organe de blocage solidaire de la roue à colonnes 6. Dans la forme d'exécution illustrée, l'organe de blocage est une roue à crochets 12 présentant des crochets 11 radialement réparti à sa circonférence.According to an essential aspect of the invention, the clutch lever 1 further controls an arm 9. In the illustrated embodiment, the arm 9 is fixed on the clutch lever 1. The free end of the arm 9 in the form of a first hook 10. The arm 9 and the first hook 10 are arranged to cooperate with a locking member integral with the column wheel 6. In the embodiment shown, the locking member is a hook wheel 12 having hooks 11 radially distributed at its circumference.

En position embrayée illustrée sur les figures 1 et 4, le bec 5 de la bascule d'embrayage 1 est engagé entre deux colonnes 6b de la roue à colonnes 6. La roue d'embrayage 2 est ainsi en prise avec la roue de chronographe 4. La roue à crochets 12 et le bras 9 sont conformés pour que dans cette position embrayée, le premier crochet 10 du bras 9 coopère avec un second crochet 11 de la roue à crochets 12 et bloque ou limite le déplacement de la bascule d'embrayage 1 dans sa première position dans laquelle la roue d'embrayage 2 est en position embrayée et en prise avec la roue de chronographe 4 lorsqu'un choc tend à déplacer ladite bascule 1 contre l'action de son ressort de bascule 7. De plus, dans cette position embrayée, le premier crochet 10 du bras 9 est également en butée entre deux crochets 11 de la roue à crochets 12 et positionne précisément la roue d'embrayage 2 pour qu'elle soit en prise correctement avec la roue de chronographe 4.In the engaged position illustrated on the figures 1 and 4 , the nose 5 of the clutch rocker 1 is engaged between two columns 6b of the column wheel 6. The clutch wheel 2 is thus engaged with the chronograph wheel 4. The hook wheel 12 and the arm 9 are shaped so that in this engaged position, the first hook 10 of the arm 9 cooperates with a second hook 11 of the hook wheel 12 and blocks or limits the movement of the clutch rocker 1 in its first position in which the wheel clutch 2 is in the engaged position and engaged with the chronograph wheel 4 when a shock tends to move said rocker 1 against the action of its rocking spring 7. In addition, in this engaged position, the first hook 10 of the arm 9 is also in abutment between two hooks 11 of the hook wheel 12 and precisely positions the clutch wheel 2 to engage correctly with the chronograph wheel 4.

En position débrayée illustrée sur les figures 2 et 3, le bec 5 de la bascule d'embrayage 1 se trouve en appui contre une colonne 6b de la roue à colonnes 6. La roue d'embrayage 2 n'est plus en prise avec la roue de chronographe 4. Dans cette position, la roue à crochets 12 et le bras 9 ne coopèrent pas.In the disengaged position illustrated on the figures 2 and 3 , the spout 5 of the clutch rocker 1 rests against a column 6b of the column wheel 6. The clutch wheel 2 is no longer engaged with the chronograph wheel 4. In this position, the hook wheel 12 and the arm 9 do not cooperate.

Dans la forme d'exécution illustrée, la roue à crochets 12 présente autant de seconds crochets 11 qu'il y a de colonnes 6b sur la roue à colonnes 6.In the illustrated embodiment, the hook wheel 12 has as many second hooks 11 as there are columns 6b on the column wheel 6.

Depuis la position embrayée de la roue d'embrayage 2 illustrée aux figures 1 et 4, l'actionnement du dispositif de commande du chronographe (non illustré) entraîne le pivotement de la roue à colonnes 6 dans le sens horaire. Comme la roue à crochets 12 est solidaire de la roue à colonnes 6, elle pivote donc simultanément à celle-ci et libère le premier crochet 10 du bras 9 de la bascule d'embrayage 1 avant que la colonne 6b de la roue à colonnes 6 ne vienne en contact avec le bec 5 de la bascule d'embrayage 1 pour faire pivoter celle-ci pour rejoindre de manière classique sa position débrayée.From the engaged position of the clutch wheel 2 illustrated in FIGS. figures 1 and 4 the actuation of the chronograph control device (not shown) causes the column wheel 6 to pivot in a clockwise direction. As the hook wheel 12 is secured to the column wheel 6, it therefore pivots simultaneously thereto and releases the first hook 10 of the arm 9 of the clutch rocker 1 before the column 6b of the column wheel 6 does not come into contact with the spout 5 of the clutch rocker 1 to rotate it to join conventionally its disengaged position.

Depuis la position débrayée illustrée à aux figures 2 et 3, l'actionnement du dispositif de commande du chronographe (non illustré) entraîne le pivotement dans le sens horaire de la roue à colonnes 6. Le bec 5 de la bascule d'embrayage 1 tombe alors dans un espace entre deux colonnes 6b de la roue à colonnes 6. Ce faisant, le premier crochet 10 du bras 9 vient en butée contre un second crochet 11 de la roue à crochet 12 qui a pivoté simultanément à la roue à colonnes 6. Les premier et second crochets 10, 11 présentent chacun un premier flan incliné 100, 110. Lorsque lesdits crochets viennent en contact, lesdits flans inclinés 100, 110 sont conformés pour qu'ils glissent l'un sur l'autre, entraînant le déplacement du premier crochet 10 par déformation élastique du bras 9 jusqu'à ce que ledit premier crochet 10 retrouve une position dans laquelle il coopère avec le second crochet 11 pour retenir la bascule d'embrayage 1.From the disengaged position shown to figures 2 and 3 , actuation of the chronograph control device (not shown) causes the clockwise rotation of the column wheel 6. The spout 5 of the clutch rocker 1 then falls in a space between two columns 6b of the wheel 6. In doing so, the first hook 10 of the arm 9 abuts against a second hook 11 of the hook wheel 12 which has pivoted simultaneously with the column wheel 6. The first and second hooks 10, 11 each have a first inclined blank 100, 110. When said hooks come into contact, said inclined blanks 100, 110 are shaped so that they slide on one another, causing the displacement of the first hook 10 by elastic deformation of the arm 9 until said first hook 10 finds a position in which it cooperates with the second hook 11 to retain the clutch lever 1.

La roue à crochets 12, le bras 9 et son premier crochet 10 sont donc conformés pour coopérer lorsque la bascule d'embrayage 1 est dans sa première position embrayée de sorte à limiter ou empêcher tout déplacement de ladite bascule 1 contre l'action de son ressort de bascule 7 sous l'effet d'un choc qui tendrait à la faire rejoindre sa position débrayée. Ainsi, même en cas de choc provoquant une force supérieure à la force du ressort de bascule 7, la bascule d'embrayage 1 est retenue dans sa première position par la roue à crochets 12 et la roue d'embrayage 2 reste en prise avec la roue de chronographe 4 sans interrompre la mesure. De plus, lorsque la roue à colonnes 6 pivote d'une première position stable correspondant à la position embrayée de la roue d'embrayage 2 à une seconde position stable correspondant à la position débrayée de la roue d'embrayage 2, la roue à crochets 12 pivote simultanément à la roue à colonnes 6 de manière à libérer le premier crochet 10 avant que la roue à colonnes 6 ne soulève la bascule d'embrayage 1 et ainsi permettre à la bascule d'embrayage 1 de rejoindre sa seconde position dans laquelle la roue d'embrayage 2 est en position débrayée.The hook wheel 12, the arm 9 and its first hook 10 are shaped to cooperate when the clutch rocker 1 is in its first engaged position so as to limit or prevent any movement of said rocker 1 against the action of its rocking spring 7 under the effect of a shock that tends to make it reach its disengaged position. Thus, even in the event of an impact causing a force greater than the force of the rocker spring 7, the clutch rocker 1 is retained in its first position by the hook wheel 12 and the clutch wheel 2 remains in engagement with the chronograph wheel 4 without interrupting the measurement. In addition, when the column wheel 6 pivots from a first stable position corresponding to the engaged position of the clutch wheel 2 to a second stable position corresponding to the disengaged position of the clutch wheel 2, the hook wheel 12 pivots simultaneously with the column wheel 6 so as to release the first hook 10 before the column wheel 6 raises the clutch rocker 1 and thus allow the clutch lever 1 to reach its second position in which the clutch wheel 2 is in the disengaged position.

Dans une première variante illustrée à la figure 5, les seconds crochets 11 de la roue à crochets 12 présentent une forme telle qu'il existe un jeu de fonctionnement JA entre lesdits crochets 11 et le premier crochet 10 du bras 9 lorsque ceux-ci coopèrent dans la position embrayée du dispositif. Pour éviter tout débrayage de la roue d'embrayage 2 et de la roue de chronographe 4 en cas de choc, les pièces sont dimensionnées de sorte que ledit jeu de fonctionnement JA permet de garantir la pénétration des dents de la roue d'embrayage 2 par rapport aux dents de la roue de chronographe 4. Dans cette première variante illustrée à la figure 5, les flans intérieurs 111, 101 respectivement des seconds crochets 11 de la roue à crochet 12 et du premier crochet 10 du bras 9 sont essentiellement parallèles.In a first variant illustrated in figure 5 , the second hooks 11 of the hook wheel 12 have a shape such that there is a play J A between said hooks 11 and the first hook 10 of the arm 9 when they cooperate in the engaged position of the device. To avoid clutching of the clutch wheel 2 and the chronograph wheel 4 in the event of an impact, the parts are dimensioned so that said operating clearance J A makes it possible to guarantee the penetration of the teeth of the clutch wheel 2 relative to the teeth of the chronograph wheel 4. In this first variant illustrated in figure 5 , the inner blanks 111, 101 respectively second hooks 11 of the hook wheel 12 and the first hook 10 of the arm 9 are substantially parallel.

Dans une seconde variante illustrée à la figure 6, les seconds crochets 11 de la roue à crochet présentent une forme telle qu'il n'existe aucun jeu de fonctionnement entre lesdits crochets 11 et le premier crochet 10 du bras 9 lorsque ceux-ci coopèrent dans la position embrayée du dispositif. Comme illustré dans la figure 6, dans cette variante, les seconds crochets 11 de la roue à crochets 12 et le premier crochet 10 du bras 9 présentent chacun un flan intérieur incliné 112, 102 de sorte que le contact entre lesdits premier et seconds crochets 10, 11 se fait en tout temps en deux points dans la première position embrayée de la bascule 1. Dans cette variante, la résistance au choc du dispositif dépend de l'inclinaison des flans intérieurs inclinés 102, 112 des premier et seconds crochets 10, 11.In a second variant illustrated in figure 6 , the second hooks 11 of the hook wheel have a shape such that there is no set of operation between said hooks 11 and the first hook 10 of the arm 9 when they cooperate in the engaged position of the device. As illustrated in figure 6 in this variant, the second hooks 11 of the hook wheel 12 and the first hook 10 of the arm 9 each have an inclined inner blank 112, 102 so that the contact between said first and second hooks 10, 11 is at all time in two points in the first engaged position of the rocker 1. In this variant, the impact resistance of the device depends on the inclination of the inclined inner blanks 102, 112 of the first and second hooks 10, 11.

Dans la forme d'exécution illustrée, le bras 9 est positionné sur la bascule d'embrayage 1 par deux goupilles de guidage 16 et maintenu par deux vis de maintien 13 vissées chacune au travers d'une rainure 15 correspondante dans la bascule d'embrayage 1. Un excentrique 14 permet de déplacer le premier crochet 10 du bras 9 par rapport à la bascule d'embrayage 1. Le réglage du dispositif d'embrayage et en particulier de la pénétration des dents de la roue d'embrayage 2 par rapport aux dents de la roue de chronographe 4 se fait alors comme suit : en position embrayée de la roue d'embrayage 2, le bec 5 de la bascule d'embrayage 2 se trouvant entre deux colonnes 6b de la roue à colonnes 6 et l'extrémité du bras 9 en butée sur la roue à crochets 12, les vis de maintien 13 sont d'abord desserrées, l'excentrique 14 est ensuite tourné au besoin entraînant le déplacement du bras 9 pour régler la position de la bascule 1 et donc de la roue d'embrayage 2. Une fois trouvée la position désirée, les vis de maintien 13 sont resserrées. La bascule d'embrayage 1 et son bras 9 sont alors parfaitement réglés.In the illustrated embodiment, the arm 9 is positioned on the clutch rocker 1 by two guide pins 16 and held by two holding screws 13 each screwed through a corresponding groove 15 in the clutch rocker 1. An eccentric 14 moves the first hook 10 of the arm 9 relative to the clutch rocker 1. The adjustment of the clutch device and in particular the penetration of the teeth of the clutch wheel 2 relative to the The teeth of the chronograph wheel 4 are then as follows: in the engaged position of the clutch wheel 2, the spout 5 of the clutch rocker 2 lying between two columns 6b of the column wheel 6 and the end of the arm 9 abutting on the hook wheel 12, the holding screws 13 are first loosened, the eccentric 14 is then rotated if necessary causing the movement of the arm 9 to adjust the position of the rocker 1 and therefore the clutch wheel 2. Once found the po desired position, the holding screws 13 are tightened. The clutch rocker 1 and its arm 9 are then perfectly adjusted.

La forme d'exécution ci-dessus a été décrite à titre d'exemple. En particulier, le mécanisme de chronographe est bien connu de l'homme du métier et pourra comprendre tout autre dispositif traditionnel (commande, remise à zéro...) sans lien avec l'invention. De même, l'invention n'est pas limitée à un dispositif d'embrayage pour un chronographe ni à un mécanisme d'embrayage.The above embodiment has been described by way of example. In particular, the chronograph mechanism is well known to those skilled in the art and may include any other traditional device (control, reset ...) unrelated to the invention. Likewise, the invention is not limited to a clutch device for a chronograph or to a clutch mechanism.

Dans la forme d'exécution décrite ci-dessus, le bras 9 est déformable élastiquement et est porté par la bascule d'embrayage. En variante, ledit bras pourrait être un doigt rigide mobile en rotation et soumis à l'action d'une force élastique appropriée telle qu'un ressort. Ledit doigt pourrait être pivoté sur la bascule d'embrayage. Il pourrait être également pivoté ailleurs sur le mouvement et être agencé pour être commandé par ladite bascule et coopérer avec ladite bascule et avec la roue à crochet de sorte que lorsque ladite bascule est dans sa position embrayée ledit doigt empêche ou limite tout déplacement de la bascule sous l'effet d'un choc.In the embodiment described above, the arm 9 is elastically deformable and is carried by the clutch rocker. Alternatively, said arm could be a rigid finger rotatable and subjected to the action of a suitable elastic force such as a spring. Said finger could be pivoted on the clutch rocker. It could also be pivoted elsewhere on the movement and be arranged to be controlled by said rocker and cooperate with said rocker and with the hook wheel so that when said rocker is in its engaged position said finger prevents or limits any displacement of the rocker under the effect of a shock.

De manière générale, l'invention se rapporte à un dispositif pour une pièce d'horlogerie comprenant un organe mobile (1) pouvant prendre au moins deux positions déterminées et un organe de commande (6) coopérant avec ledit organe mobile (1) pour définir lesdites au moins deux positions déterminées. Le dispositif comprend en outre un organe de verrouillage (12) solidaire de la came de commande (6) et un organe intermédiaire (9) commandé par l'organe mobile (1). L'organe intermédiaire (9) est destiné à coopérer avec l'organe de verrouillage (12) et l'organe mobile (1) pour empêcher ou limiter le déplacement dudit organe mobile (1) sous l'effet d'un choc lorsque l'organe mobile (1) est dans l'une des ces positions déterminées, évitant ainsi que ledit organe mobile (1) ne quitte sa position déterminée.In general, the invention relates to a device for a timepiece comprising a movable member (1) that can take at least two determined positions and a control member (6) cooperating with said movable member (1) to define said at least two predetermined positions. The device further comprises a locking member (12) integral with the control cam (6) and an intermediate member (9) controlled by the movable member (1). The intermediate member (9) is intended to cooperate with the locking member (12) and the movable member (1) to prevent or limit the displacement of said movable member (1) under the effect of a shock when the movable member (1) is in one of these determined positions, thus preventing said movable member (1) from leaving its determined position.

On réalise ainsi un dispositif multi positions, comme par exemple un dispositif d'embrayage, qui résiste aux chocs et dont la sécurité de fonctionnement et la précision sont améliorées, tout en restant simple et facile à régler.This produces a multi-position device, such as a clutch device, which is shock-resistant and whose operational safety and accuracy are improved, while remaining simple and easy to adjust.
