Description

Domaine de l'inventionField of the invention

L'invention concerne un ensemble barillet pour montre mécanique avec diamètre de bonde réduit.The invention relates to a barrel assembly for a mechanical watch with reduced bung diameter.

L'invention concerne encore un mouvement d'horlogerie comportant au moins un tel ensemble barillet.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 2 287 717 A1 au nom de SCHILD décrit un barillet avec une roue à rochet fixée à l'arbre et adjacente au pont dans lequel pivote cet arbre. Il comporte un cliquet en une pièce, formé d'une partie rigide mobile en rotation autour de l'arbre entre une position de blocage et une position de dégagement, et d'un bras élastique dont l'extrémité libre présente un bec d'encliquetage capable de s'engager dans la denture du rochet. Ce cliquet est logé dans une creusure du pont entre le pont et la roue à rochet. Le bras présente à son extrémité libre un élément d'appui situé à l'intérieur du contour du rochet, les flancs de cette creusure comprennent deux éléments de butée coopérant, en position de blocage, l'un avec l'élément d'appui, et l'autre avec le bec d'encliquetage, pour déterminer la position de blocage.The document FR 2 287 717 A1 in the name of SCHILD describes a barrel with a ratchet wheel attached to the shaft and adjacent to the bridge in which this shaft pivots. It comprises a pawl in one piece, formed of a rigid portion rotatable about the shaft between a locking position and a release position, and an elastic arm whose free end has a detent able to engage in the teeth of the ratchet. This pawl is housed in a recess of the bridge between the bridge and the ratchet wheel. The arm has at its free end a bearing element situated inside the contour of the ratchet, the flanks of this recess comprise two abutment elements cooperating, in the locked position, one with the support element, and the other with the latching nose, to determine the locking position.

Le document FR 1 371 491 A au nom de PONS décrit un procédé et un dispositif de lubrification. Le rochet fixé sur l'arbre de barillet présente des ouvertures d'accès sur une partie du pont de barillet ou sur une partie du coussinet supérieur du barillet. Le pont peut présenter des ouvertures similaires, ainsi que la platine pour l'accès au coussinet du couvercle.The document FR 1 371 491 A in the name of PONS describes a method and a lubricating device. The ratchet attached to the barrel shaft has access openings on a portion of the barrel bridge or on a portion of the upper barrel bushing. The deck may have similar openings, as well as the deck for access to the cover pad.

Le document US 886 196 A au nom de FALLER LEWIS ALBERT. Le tambour et le couvercle d'un barillet pivotent de façon limitée par les parois d'une cavité formée par une platine et un pont plaqués l'un sur l'autre. Le tambour pivote autour de l'axe de barillet par l'intermédiaire d'une bague qui comporte deux plats qui coopèrent avec une lumière oblongue du tambour. Cette bague porte, par un filetage, le rochet qui pivote de façon limitée par les parois d'une cavité définie par la platine et le tambour. L'arbre porte, du côté opposé, une roue entre le couvercle et le pont.The document US 886196A on behalf of FALLER LEWIS ALBERT. The barrel and the lid of a barrel pivot in a limited manner by the walls of a cavity formed by a plate and a bridge clad on each other. The drum pivots about the barrel axis through a ring that has two flats that cooperate with an oblong slot of the drum. This ring carries, by a thread, the ratchet which pivots in a limited way by the walls of a cavity defined by the plate and the drum. The shaft carries, on the opposite side, a wheel between the cover and the bridge.

Le document CH 295 135 A au nom de BRAC décrit un barillet dont la bonde porte le rochet, dont le mouvement est limité par un filet sur la platine. Cette bonde pivote sur un axe dont une extrémité coopère avec un alésage de la platine, et dont l'autre extrémité comporte un filetage. Ce filetage coopère avec le taraudage d'un boîtier de centrage monté dans un alésage du pont. Le filetage et la plaque support maintiennent une bague de centrage faisant butée pour l'extrémité de la bonde du côté du pont.The document CH 295 135 A in the name of BRAC describes a barrel whose bonde carries the ratchet, whose movement is limited by a net on the plate. This bung pivots on an axis whose one end cooperates with a bore of the plate, and the other end has a thread. This thread cooperates with the tapping of a centering box mounted in a bore of the bridge. The thread and the support plate hold a centering ring abutting the end of the bung on the side of the bridge.

Le document EP 2 196 866 A2 au nom de ARTISANS HORLOGERS SARL concerne une fixation à baïonnette du rochet sur un carré d'extrémité de l'arbre. Il combine un profil d'entraînement non circulaire à l'extrémité de l'arbre, qui est séparé, par une gorge, d'un épaulement pour un appui en butée du rochet. Le rochet comporte une découpe de forme complémentaire à ce profil d'entraînement non circulaire, sur lequel il est enfilé puis mis en butée sur la collerette. Une rondelle de fixation comporte une découpe de forme complémentaire au profil d'entraînement non circulaire de l'arbre, sur lequel elle est enfilée. Cette rondelle est ensuite vissée sur le rochet par au moins une vis excentrique.The document EP 2 196 866 A2 in the name of ARTISANS HORLOGERS SARL concerns a bayonet attachment of the ratchet on an end square of the tree. It combines a non-circular drive profile at the end of the shaft, which is separated by a groove, a shoulder for abutment abutment of the ratchet. The ratchet has a shape complementary shape to this non-circular drive profile, on which it is threaded and then abutted on the collar. A fixing washer has a cut complementary shape to the non-circular drive profile of the shaft, on which it is threaded. This washer is then screwed on the ratchet by at least one eccentric screw.
