Description

Domaine de l'inventionField of the invention

L'invention concerne un ensemble barillet pour montre mécanique avec diamètre de bonde réduit selon la revendication 1. L'invention concerne encore un mouvement d'horlogerie comportant au moins un tel ensemble barillet.The invention relates to a barrel assembly for a mechanical watch with reduced bung diameter according to claim 1. The invention also relates to a watch movement comprising at least one such barrel assembly.

L'invention concerne encore une pièce d'horlogerie comportant au moins un tel mouvement ou/et au moins un tel ensemble barillet.The invention also relates to a timepiece comprising at least one such movement and / or at least one such barrel assembly.

L'invention concerne le domaine de l'horlogerie, et plus particulièrement le domaine des barillets de stockage d'énergie, pour l'alimentation d'un mouvement, d'une sonnerie, ou d'une autre fonctionnalité d'une pièce d'horlogerie.The invention relates to the field of watchmaking, and more particularly the field of energy storage barrels, for feeding a movement, a ring, or other functionality of a room watchmaking.

Arrière-plan de l'inventionBackground of the invention

Pour augmenter la réserve de marche, par augmentation du nombre de tours d'un ressort de barillet, une solution consiste en une diminution du diamètre de l'arbre de barillet et de la bonde associée, de façon à augmenter la place disponible dans le tambour pour le ressort.To increase the power reserve, by increasing the number of turns of a mainspring, one solution consists of a decrease in the diameter of the barrel shaft and the associated bung, so as to increase the space available in the drum. for the spring.

Le rapport du rayon de bonde par rapport à l'épaisseur du ressort est usuellement compris entre 10 et 20, et l'invention se propose d'abaisser ce rapport en-dessous de 10, et préférentiellement dans la plage comprise entre 5 et 10.The ratio of the bead radius to the thickness of the spring is usually between 10 and 20, and the invention proposes to lower this ratio below 10, and preferably in the range between 5 and 10.

Le dimensionnement ne doit pas être fait à la légère, en effet un risque de casse existe sir le diamètre de la bonde est trop faible.Sizing should not be done lightly, indeed a risk of breakage exists if the diameter of the plug is too small.

Dans l'architecture classique des barillets, un rochet est monté axialement sur un axe de barillet ou sur une bonde, par l'intermédiaire d'un carré, le rochet étant généralement fixé par une vis axiale. La dimension de cette vis et celle du carré conditionnent donc un diamètre minimal d'une portée de pivotement. Un épaulement jointif à cette portée de pivotement limite l'ébat axial de l'arbre ou de la bonde par rapport à une platine ou à un pont porteur d'une pierre ou similaire.In the conventional architecture of the barrels, a ratchet is mounted axially on a barrel axis or on a bung, via a square, the ratchet being generally fixed by an axial screw. The size of this screw and that of the square thus condition a minimum diameter of a pivoting surface. A shoulder abutting with this pivoting surface limits axial fretting of the shaft or the bung relative to a plate or bridge carrying a stone or the like.

Un diamètre encore supérieur à celui de cet épaulement est nécessaire pour une portée de guidage en pivotement du tambour sur l'arbre ou sur la bonde, combinée à un épaulement de limitation de l'ébat axial du tambour. Le respect de sections de matière minimales implique une chaîne de cotation qui se traduit par un encombrement conséquent, difficile à réduire. On ne peut en particulier pas se contenter de réduire l'ensemble des dimensionnements, car les sections de matière sont alors insuffisantes pour assurer la tenue en fatigue.A diameter even greater than that of this shoulder is necessary for a pivoting guide surface of the drum on the shaft or on the bung, combined with a shoulder limiting axial fretting of the drum. The respect of minimal sections of matter implies a quotation chain which results in a large size, difficult to reduce. In particular, it is not enough to reduce all the sizing, because the sections of material are then insufficient to ensure fatigue resistance.

Le document FR 306 103 au nom de Etablissements PARRENIN décrit une bonde creuse, de longueur égale à l'épaisseur du barillet, dans lequel un axe amovible plus long pivote dans une platine et un pont. La bonde et l'axe comportent des moyens complémentaires d'entraînement en pivotement, par un carré, tout en autorisant un mouvement axial relatif entre eux, l'une des extrémités de l'axe comportant un carré épaulé d'entraînement d'un rochet. Ce rochet est maintenu à l'extérieur du barillet, au-delà du pont. Un tambour pivote sur une portée épaulée de la bonde, et un couvercle fixé à ce tambour pivote sur une autre portée épaulée de cette bonde. L'ébat du tambour par rapport à cette bonde est limité par les deux épaulements de ces deux portées épaulées de sens contraire. L'ébat de la bonde par rapport à l'axe est limité, du côté du rochet, par un épaulement de l'axe coopérant avec une face en bout de la bonde, tandis qu'à l'autre extrémité l'autre face en bout de la bonde vient en appui sur la platine. La limitation de l'ébat de l'axe par rapport à la platine et au pont, est assurée dans un sens, ou bien de façon indirecte, par la bonde coopérant avec l'épaulement de l'arbre, ou bien par l'appui du rochet sur le pont, tandis que dans l'autre sens il est nécessaire de rajouter, au-delà de l'extrémité de l'axe munie du carré d'entraînement du rochet, une butée amovible, ou bien un pont supplémentaire. Le document CH 324 249 au nom de COMPAGNIE DES MONTRES LONGINES, FRANCILLON S.A. décrit un rochet monobloc avec l'arbre de barillet entre des portées de guidage de cet arbre dans la platine et le pont. Cet arbre comporte des moyens d'entraînement en pivotement d'une bonde porteuse du ressort, et sur laquelle bonde pivotent un tambour et un couvercle associé, qui enserrent la bonde sans jeu axial. L'ébat de l'arbre est limité, dans un sens par l'appui du rochet sur le pont, et dans l'autre sens, indirectement par l'intermédiaire de la bonde en appui par une première face de bout sur une face intérieure du rochet, sa face de bout opposée venant en appui sur la platine.The document FR 306 103 in the name of Etablissements PARRENIN describes a hollow bung, of length equal to the thickness of the barrel, in which a longer removable axis pivots in a plate and a bridge. The bung and the axis comprise complementary means of pivoting drive, by a square, while allowing an axial movement relative to each other, one of the ends of the axis comprising a square shouldered driving a ratchet . This ratchet is kept outside the barrel, beyond the bridge. A drum pivots on a shouldered shoulder of the bung, and a lid attached to this drum pivots on another shouldered bearing of this bung. The frolicking of the drum with respect to this bung is limited by the two shoulders of these two shoulders in opposite directions. The fringe of the bung relative to the axis is limited, on the side of the ratchet, by a shoulder of the axis cooperating with one end face of the bung, while at the other end the other face in end of the bung comes to bear on the plate. The limitation of the fretting of the axis with respect to the plate and the bridge, is provided in one direction, or indirectly, by the bung cooperating with the shoulder of the tree, or by the support of the ratchet on the bridge, while in the other direction it is necessary to add, at the beyond the end of the axis provided with the square drive ratchet, removable stop, or an additional bridge. The document CH 324 249 in the name of COMPAGNIE DES MONTRES LONGINES, FRANCILLON SA describes a one-piece ratchet with the barrel shaft between guide bearings of this shaft in the plate and the bridge. This shaft comprises pivoting drive means of a spring-loaded bung, and on which bung pivot a drum and an associated lid, which enclose the bung without axial play. The fretting of the shaft is limited, in one direction by the support of the ratchet on the bridge, and in the other direction, indirectly via the bung supported by a first end face on an inner face ratchet, its opposite end face bearing on the plate.

Un document DE 18 72 388 au nom de EPPLE KG OTERO UHREN décrit un mécanisme de fort encombrement en épaisseur, et où la limitation d'ébat est faite par une lame-ressort coopérant avec une gorge de l'arbre, entre le pont et le tambour.A document DE 18 72 388 In the name of EPPLE KG OTERO UHREN describes a mechanism of great bulk in thickness, and where the frolicking limitation is made by a leaf spring cooperating with a groove of the shaft, between the bridge and the drum.

Le document US 1 110 061 au nom de KIENZLE décrit un arbre de barillet coiffé d'une bonde, l'arbre comporte une rainure parallèle à son axe, dans laquelle une goupille longitudinale fait fonction de came d'embrayage/débrayage entre la bonde et l'arbre selon le sens de pivotement de l'arbre. Le tambour pivote sur la bonde, ainsi que le couvercle fixé sur le tambour. La bonde a une longueur correspondant juste à l'entraxe entre platine et pont, et l'arbre peut être enfilé dans la bonde après insertion latérale de l'ensemble formé par la bonde, le ressort, le tambour et le couvercle. L'ébat du tambour est limité par le pont dans un sens, et par un épaulement de la bonde dans l'autre sens. La limitation de l'ébat de l'arbre par rapport à la platine et au pont nécessite, là encore, une bride rapportée sur le pont et limitant la course du rochet. Le document CH 295 135 au nom de BRAC AG décrit un arbre lisse comportant une tête retenue par un épaulement d'une douille de centrage d'une platine, l'autre extrémité lisse de cet arbre pivotant dans un pont. Un tambour et un couvercle enserrent avec un jeu axial, entre deux épaulements, une bonde coaxiale à l'arbre. Du côté lisse de l'arbre, la bonde porte un rochet. La limitation de l'ébat axial de la bonde, dans le même sens que l'appui de la tête de l'arbre dans le centrage, est faite par l'appui du rochet sur un filet du pont, et dans le sens inverse par l'appui d'une face en bout de la bonde sur ce centrage. La douille de centrage représente une épaisseur supplémentaire du barillet.The document US 1 110 061 in the name of KIENZLE describes a barrel shaft capped with a bung, the shaft has a groove parallel to its axis, in which a longitudinal pin acts as a cam clutch / disengagement between the bung and the shaft in the direction pivoting of the shaft. The drum pivots on the bung, as well as the lid fixed on the drum. The bung has a length corresponding to just the center distance between platinum and bridge, and the shaft can be threaded in the bung after lateral insertion of the assembly formed by the bung, the spring, the drum and the lid. The frolicking of the drum is limited by the bridge in one direction, and by a shoulder of the bung in the other direction. The limitation of the fretting of the shaft relative to the plate and the bridge requires, again, a flange reported on the bridge and limiting the race of the ratchet. The document CH 295 135 in the name of BRAC AG describes a smooth shaft having a head retained by a shoulder of a centering sleeve of a plate, the other smooth end of this shaft pivoting in a bridge. A drum and a cover grip with axial clearance, between two shoulders, a plug coaxial with the shaft. On the smooth side of the tree, the bung carries a ratchet. The limitation of the axial fretting of the bung, in the same direction as the support of the head of the shaft in the centering, is made by the support of the ratchet on a net of the bridge, and in the opposite direction by the support of a face at the end of the bung on this centering. The centering sleeve represents an additional thickness of the barrel.

Le document US 182 629 au nom de BARCLAY représente un barillet de sécurité comportant un mécanisme de protection de surcharge avec des coins mobiles radialement poussés par un ressort annexe.The document US 182,629 in the name of BARCLAY represents a safety cylinder comprising an overload protection mechanism with movable wedges radially pushed by an auxiliary spring.

Le document FR 1 473 744 au nom de GHIELMETTI décrit un barillet particulier, qui comporte un couvercle muni de fentes coopérant avec des ergots d'une bande non-métallique insérée entre le ressort et un ressort-lame auxiliaire.The document FR 1 473 744 in the name of GHIELMETTI describes a particular barrel, which has a cover provided with slots cooperating with lugs of a non-metallic strip inserted between the spring and an auxiliary leaf spring.
