Abstract

The member has a hairspring comprising a blade located in a plane, where an internal end of the hairspring is fixed to a pivot shaft. An external end of the hairspring is manufactured with an annular connecting member to a frame i.e. balance bridge (9) or to an angular positioning member (6) of the regulator member to the bridge. The connecting member and the bridge or the angular positioning member provide support surfaces partially complementary and parallel to a plane of the hairspring. A fixing unit assembles the complementary support surfaces.

Description

La présente invention se rapporte à un organe régulateur balancier-spiral comportant un arbre monté pivotant sur le bâti d'une pièce d'horlogerie, dans lequel le ressort spiral dudit organe régulateur comporte au moins une lame située dans un plan, dont l'extrémité interne est destinée à être fixée audit arbre de pivotement et dont l'extrémité externe est venue de fabrication avec un organe de liaison audit bâti, la rigidité de cet organe de liaison étant sensiblement supérieure à celle du spiral. L'invention se rapporte encore à un mouvement horloger ou à une pièce d'horlogerie comprenant un tel organe régulateur.The present invention relates to a balance spring-balance control member comprising a shaft pivotally mounted on the frame of a timepiece, wherein the spiral spring of said regulator member comprises at least one blade located in a plane, whose end internal is intended to be fixed to said pivot shaft and the outer end of which is manufactured with a connecting member to said frame, the rigidity of this connecting member being substantially greater than that of the spiral. The invention also relates to a watch movement or a timepiece comprising such a regulating member.

Plusieurs manières de solidariser l'extrémité extérieure du ressort spiral au bâti de la pièce d'horlogerie sont connues. En général, cette extrémité est fixe, à l'inverse de l'extrémité intérieure qui est solidaire d'une virole chassée sur l'arbre du balancier et qui oscille avec le régulateur balancier-spiral. Dans la plupart des cas, l'extrémité extérieure du spiral est reliée à un piton ou à une bride de fixation qui est ensuite solidarisé à un pont de balancier.Several ways of securing the outer end of the spiral spring to the frame of the timepiece are known. In general, this end is fixed, unlike the inner end which is secured to a ferrule driven on the balance shaft and oscillates with the spring balance regulator. In most cases, the outer end of the hairspring is connected to a peg or a fixing flange which is then secured to a pendulum bridge.

Une manière de solidariser l'extrémité du ressort spiral à un piton consiste à la placer dans un trou prévu à cet effet dans le piton puis à la bloquer au moyen d'une goupille ou par collage. Le piton est ensuite introduit dans un logement correspondant et fixé en position par chassage ou au moyen d'une vis.One way to secure the end of the spiral spring to a bolt is to place it in a hole provided for this purpose in the bolt and then block by means of a pin or by gluing. The stud is then introduced into a corresponding housing and fixed in position by driving or by means of a screw.

La position du ressort spiral par rapport à l'arbre de balancier doit être réglée de façon précise, car un décentrage du ressort spiral ou un défaut de perpendicularité par rapport à cet arbre génère des défauts chronométriques importants, en particulier au niveau de l'isochronisme du régulateur. Le piton doit donc être perpendiculaire au plan du ressort spiral et positionné de façon précise pour garantir un développement concentrique du ressort spiral. Avec des ressorts spiraux traditionnels en alliage métallique, une fois l'extrémité externe du ressort spiral fixée au pont de balancier, directement ou par l'intermédiaire d'un organe de réglage angulaire, les défauts induits par rapport à la forme tridimensionnelle idéale du ressort spiral sont corrigés par déformation plastique de l'extrémité extérieure du ressort spiral. Il s'agit là d'une opération très délicate qui ne peut être exécutée que par un horloger expérimenté. En outre, un tel mode de correction est naturellement inadapté aux ressorts spiraux réalisés dans une matière fragile telle que le silicium, car ce genre de matière ne se déforme pas plastiquement.The position of the spiral spring with respect to the rocker shaft must be precisely adjusted, because an off-centering of the spiral spring or a defect of perpendicularity with respect to this shaft generates significant chronometric defects, in particular at the level of isochronism of the regulator. The piton must be perpendicular to the plane spiral spring and precisely positioned to ensure a concentric development of the spiral spring. With traditional metal alloy spiral springs, once the outer end of the spiral spring attached to the balance bridge, directly or through an angular adjustment member, the induced defects with respect to the ideal three-dimensional shape of the spring spiral are corrected by plastic deformation of the outer end of the spiral spring. This is a very delicate operation that can only be performed by an experienced watchmaker. In addition, such a mode of correction is naturally unsuitable for spiral springs made in a fragile material such as silicon, because this kind of material does not plastically deform.

Des organes régulateurs balancier-spiral dont l'extrémité externe du ressort spiral est venue de fabrication avec un organe de liaison au bâti et dont la rigidité est sensiblement supérieure à celle du ressort spiral ont déjà été décrits, notamment dans le EP 1515200 ou dans le WO 2006/123095 ou dans le EP2151722 . Toutefois, les modes de fixation de l'extrémité externe proposés s'apparentent toujours au mode de fixation traditionnel par piton, de sorte qu'ils ne donnent qu'un point d'attache qui ne garantit pas que le ressort spiral en position de repos conserve l'intégrité tridimensionnelle de sa forme initiale après sa fixation.Balance-sprung regulating members whose outer end of the spiral spring has come from manufacture with a frame connecting member and whose rigidity is substantially greater than that of the spiral spring have already been described, in particular in the EP 1515200 or in the WO 2006/123095 or in the EP2151722 . However, the modes of attachment of the outer end proposed always look like the traditional fastening mode per pin, so that they give only one point of attachment that does not guarantee that the spiral spring in the rest position preserves the three-dimensional integrity of its initial shape after fixation.

Ces solutions ne permettent donc pas de résoudre le problème de la fixation de l'extrémité externe d'un ressort spiral ne nécessitant plus de correction après fixation. Il n'est en effet pas possible de garantir que de telles fixations traditionnelles n'induisent aucune déformation du ressort spiral et qu'elles permettent de garantir un développement concentrique du ressort spiral par rapport à l'axe de pivotement du balancier lors de l'oscillation du régulateur balancier-spiral, ainsi que la perpendicularité du ressort spiral à cet axe.These solutions do not therefore solve the problem of fixing the outer end of a spiral spring no longer requiring correction after fixation. It is not possible to guarantee that such traditional fasteners do not induce any deformation of the spiral spring and that they make it possible to guarantee a concentric development of the spiral spring with respect to the pivot axis of the rocker during the oscillation of the sprung-balance regulator, and the perpendicularity of the spiral spring to this axis.

Lorsque le ressort spiral est réalisé en un matériau fragile, tel que le silicium, le diamant ou le quartz, l'ajustement par déformation plastique du ressort spiral n'étant plus possible, l'utilisation d'un piton suppose alors d'avoir des tolérances de fabrication très serrées et un assemblage piton-spiral robuste pour garantir une parfaite perpendicularité ou aussi parfaite que possible entre l'axe du piton et le plan du ressort spiral, ce qui constitue évidemment une difficulté majeure à l'échelle industrielle. En effet, le serrage du piton dans son logement, par exemple au moyen d'une vis, est à lui seul déjà susceptible d'induire des modifications de son orientation et donc de la forme tridimensionnelle initiale du ressort spiral.When the spiral spring is made of a fragile material, such as silicon, diamond or quartz, the adjustment by plastic deformation of the spiral spring is no longer possible, the use of a pin then assumes to have very tight manufacturing tolerances and a robust piton-spiral assembly to ensure perfect perpendicularity or as perfect as possible between the axis of the stud and the plane of the spiral spring, which is obviously a major difficulty on an industrial scale. Indeed, the clamping of the stud in its housing, for example by means of a screw, is alone already likely to induce changes in its orientation and thus the initial three-dimensional shape of the spiral spring.

On a déjà proposé, notamment dans le EP 1 918 791 , d'équiper le piton de moyens permettant de modifier sa position angulaire ou sa position radiale, afin de corriger les défauts relatifs au développement concentrique du ressort spiral sans nécessiter de déformation plastique du ressort spiral. Cette solution ne permet cependant pas de corriger les défauts de perpendicularité du ressort spiral par rapport à l'axe du balancier. Cette solution nécessite également une grande habileté pour venir effectuer un réglage très précis sur un élément situé en bout de ressort spiral, et donc sujet à de grands bras de levier.It has already been proposed, particularly in EP 1 918 791 , equipping the bolt with means making it possible to modify its angular position or its radial position, in order to correct the defects relating to the concentric development of the spiral spring without requiring plastic deformation of the spiral spring. This solution, however, does not correct the perpendicularity defects of the spiral spring relative to the axis of the balance. This solution also requires great skill to come and make a very precise adjustment on an element located at the end of spiral spring, and therefore subject to large lever arms.

Le but de la présente invention est de remédier, au moins en partie, aux inconvénients susmentionnés.The object of the present invention is to overcome, at least in part, the aforementioned drawbacks.

A cet effet, l'invention a pour objet un régulateur balancier-spiral selon la revendication 1.For this purpose, the subject of the invention is a balance spring-balance regulator according to claim 1.

Différents modes de réalisation du régulateur sont définis par les revendications dépendantes 2 à 17.Different embodiments of the regulator are defined by dependent claims 2 to 17.

Le mouvement ou la pièce d'horlogerie selon l'invention est défini par la revendication 18.The movement or the timepiece according to the invention is defined by claim 18.

Avantageusement, le profil et l'étendue angulaire des surfaces d'appui complémentaires respectives de l'organe de liaison et du bâti ou d'un organe de positionnement angulaire du régulateur au bâti sont conformés et dimensionnés pour conserver, à l'état de repos, l'intégrité tridimensionnelle de la forme initiale du ressort spiral, après fixation des surfaces d'appui complémentaires l'une à l'autre.Advantageously, the profile and the angular extent of the respective complementary bearing surfaces of the connecting member and the frame or of an angular positioning member of the regulator to the frame are shaped and dimensioned to preserve, in the state of rest , the three-dimensional integrity of the initial shape of the spiral spring, after attachment of complementary bearing surfaces to each other.

L'étendue angulaire des surfaces d'appui peut être importante. Elle peut aller jusqu'à 360°, ce qui permet de conférer un appui extrêmement stable. De telles surfaces d'appui complémentaires peuvent être obtenues avec une très grande précision. A tolérance de fabrication égale, une grande surface d'appui, ou plusieurs surfaces d'appui distinctes disposées le long de l'organe de liaison avec un grand écart angulaire, confèrera une meilleure stabilité géométrique à l'ensemble. La surface d'appui solidaire de l'extrémité externe du ressort spiral est avantageusement venue de fabrication avec le ressort spiral, notamment lorsque le ressort spiral est découpé dans une plaquette de silicium, ce qui permet d'atteindre une très grande précision.The angular extent of the bearing surfaces can be significant. It can go up to 360 °, which gives an extremely stable support. Such complementary bearing surfaces can be obtained with very high accuracy. With equal manufacturing tolerance, a large bearing surface, or several distinct bearing surfaces arranged along the connecting member with a large angular gap, will confer a better geometric stability to the assembly. The bearing surface secured to the outer end of the spiral spring is advantageously manufactured by the spiral spring, especially when the spiral spring is cut in a silicon wafer, which achieves a very high accuracy.

Avantageusement, les surfaces d'appui respectives au moins partiellement complémentaires de l'organe de liaison et du bâti ou de l'organe de positionnement angulaire du régulateur au bâti comportent au moins deux éléments de positionnement de l'extrémité externe du ressort spiral par rapport à l'axe de l'arbre de balancier et à la fixation de l'extrémité interne du ressort spiral sur l'arbre de balancier, afin d'assurer une position desdites extrémités qui soit aussi précise que permis par les tolérances. Idéalement, ces éléments de positionnement permettent de conserver la forme initiale du ressort spiral en position de repos de l'organe régulateur.Advantageously, the respective bearing surfaces at least partially complementary to the connecting member and the frame or the angular positioning member of the regulator to the frame comprise at least two positioning elements of the outer end of the spiral spring relative to to the axis of the balance shaft and the fixing of the inner end of the spiral spring on the balance shaft, to ensure a position of said ends which is as precise as allowed by the tolerances. Ideally, these positioning elements make it possible to keep the initial shape of the spiral spring in the rest position of the regulating member.

Les figures 1 à 8 illustrent huit variantes de ressorts spiraux 1 dont l'extrémité externe est venue de fabrication avec un organe de liaison 2 au bâti d'une pièce d'horlogerie. La rigidité de cet organe de liaison 2 est sensiblement supérieure à celle du spiral 1, typiquement 1000 fois plus élevée dans le plan du spiral, et 10 fois plus élevée perpendiculairement au plan du spiral. De préférence, les extrémités internes de ces ressorts spiraux sont aussi venues de fabrication avec une virole de fixation 3, destinée à être chassée, comme d'habitude, sur l'arbre de pivotement d'un balancier. Comme on peut le constater, l'organe de liaison 2 s'étend angulairement par rapport à l'axe de pivotement de l'arbre sur lequel doit être chassée la virole 3. De ce fait, cet organe de liaison est apte à fournir au moins une surface d'appui stable au ressort spiral 1 pour autant qu'elle soit associée à une surface d'appui au moins partiellement complémentaire comme on le verra par la suite. Ces surfaces d'appui sont sensiblement parallèles au plan du ressort spiral 1.The Figures 1 to 8 illustrate eight variants of spiral springs 1 whose outer end came from manufacture with a connecting member 2 to the frame of a timepiece. The rigidity of this connecting member 2 is substantially greater than that of the hairspring 1, typically 1000 times higher in the plane of the hairspring, and 10 times higher perpendicularly to the plane of the hairspring. Preferably, the inner ends of these spiral springs are also manufactured with a fixing ferrule 3, intended to be driven, as usual, on the pivot shaft of a beam. As can be seen, the connecting member 2 extends angularly with respect to the axis of pivoting of the shaft on which the shell 3 is to be driven. As a result, this connecting member is able to provide the minus one surface of stable support to the spiral spring 1 as long as it is associated with a support surface at least partially complementary as will be seen later. These bearing surfaces are substantially parallel to the plane of the spiral spring 1.

Selon les variantes des figures 1 à 7, l'organe de liaison 2 comporte avantageusement deux, voire trois éléments de positionnement et de fixation, constitués par des ouvertures 4 pour le passage d'organes de fixation, notamment de goupilles ou de vis. Ces ouvertures sont de préférences réparties angulairement pour permettre d'appliquer l'organe de liaison 2 contre la surface d'appui complémentaire en plusieurs points de sa surface d'appui. De cette manière et dans la limite des tolérances admises, une fois l'organe de liaison fixé à sa surface d'appui complémentaire, le ressort spiral conserve à l'état de repos l'intégrité tridimensionnelle de sa forme initiale.According to the variants of Figures 1 to 7 , the connecting member 2 advantageously comprises two or three positioning and fixing elements, constituted by openings 4 for the passage of fasteners, including pins or screws. These openings are preferably angularly distributed to allow to apply the connecting member 2 against the complementary bearing surface at several points of its bearing surface. In this way and within the limits of tolerances allowed, once the connecting member fixed to its complementary bearing surface, the spiral spring retains in the state of rest the three-dimensional integrity of its initial shape.

Comme illustré par les figures 6 et 7, certaines des ouvertures 4a peuvent être non-circulaires, par exemple de forme allongée, pour permettre de corriger de petits défauts de centrage pouvant provenir des tolérances admises. C'est ainsi que l'ouverture de forme allongée 4a peut être associée à un organe de réglage excentrique dont le déplacement angulaire permettra d'ajuster finement le centrage du spiral par rapport au bâti, par une rotation de l'organe de liaison 2 par rapport au centre de l'ouverture 4, le serrage de l'organe de liaison 2 intervenant après le centrage du ressort spiral 1. La finesse du positionnement est proportionnelle à l'écartement entre les ouvertures 4 et 4a. L'organe de réglage excentrique peut aussi être associé à l'ouverture circulaire 4, mais cette variante est moins favorable pour le réglage vu qu'elle implique que les deux ouvertures 4, 4a se déplacent sous l'effet de l'organe de réglage.As illustrated by Figures 6 and 7 , some of the openings 4a may be non-circular, for example of elongate shape, to allow correction of small centering defects may come from tolerances allowed. Thus, the elongated opening 4a may be associated with an eccentric adjusting member, the angular displacement of which will make it possible to finely adjust the centering of the hairspring relative to the frame, by a rotation of the connecting member 2 by relative to the center of the opening 4, the clamping of the connecting member 2 occurring after the centering of the spiral spring 1. The fineness of the positioning is proportional to the spacing between the openings 4 and 4a. The eccentric adjustment member may also be associated with the circular opening 4, but this variant is less favorable for the adjustment since it implies that the two openings 4, 4a move under the effect of the adjustment member.

La variante de la figure 8 se rapporte à un organe de liaison 2 annulaire, ici associé à un ressort spiral à deux lames décalées angulairement de 180°, dans lequel l'organe de liaison 2 ne comporte pas d'élément de positionnement et de fixation. La fixation d'un tel organe de liaison 2 annulaire peut être obtenue par exemple comme illustré par les figures 20 à 22 que l'on décrira ci-après.The variant of the figure 8 relates to an annular connecting member 2, here associated with a spiral spring with two blades angularly offset by 180 °, wherein the connecting member 2 has no positioning and fixing element. Fixing such an annular connecting member 2 can be obtained for example as illustrated by the Figures 20 to 22 which will be described below.

L'organe de liaison annulaire 2 de la figure 8 est évidemment aussi utilisable avec un ressort spiral à une seule lame, comme ceux des figures 1 à 7. Inversement, les organes de liaison annulaire 2 des figures 1-7 sont aussi utilisables avec des ressorts spiraux à plusieurs lames.The annular link 2 of the figure 8 is obviously also usable with a spiral spring with a single blade, as those of Figures 1 to 7 . Conversely, the annular connecting members 2 of the Figures 1-7 can also be used with spiral springs with multiple blades.

Différentes solutions sont possibles pour fixer l'organe de liaison 2 au bâti du mouvement d'horlogerie. Soit cet organe de liaison est fixé directement au pont de balancier, soit, avantageusement, il est fixé au pont de balancier par une pièce intermédiaire, montée pivotante autour de l'axe de pivotement de l'arbre du balancier, ce qui permet de régler le repère sur le mouvement d'horlogerie. Le réglage du repère consiste à amener le centre de la cheville de plateau du balancier sur la ligne reliant les centres de pivotement respectifs du balancier et de l'ancre, lorsque l'organe régulateur balancier-spiral est en position d'équilibre.Different solutions are possible for fixing the connecting member 2 to the frame of the watch movement. Either this connecting member is fixed directly to the balance bridge, or, advantageously, it is fixed to the balance bridge by an intermediate piece, pivotally mounted about the pivot axis of the balance shaft, which allows to adjust the landmark on the watch movement. The setting of the marker consists of bringing the center of the balance plate pin on the line connecting the respective pivot centers of the balance and the anchor, when the balance-sprung regulator member is in the equilibrium position.

Les figures 9 à 12 illustrent une première variante d'une première forme d'exécution, dans laquelle l'organe de liaison 2 comporte au moins deux éléments de positionnement et des surfaces d'appui correspondantes. On reconnaît sur la figure 9 un ressort spiral 1 similaire à celui illustré par la figure 1. Deux goupilles de fixation 5 sont destinées à traverser les ouvertures 4 de l'organe de liaison 2 et à être chassées dans des ouvertures correspondantes 6a ménagées dans une pièce intermédiaire 6, munie d'une ouverture 6b concentrique à l'axe central de la virole 3 après assemblage des éléments de la figure 9. L'ouverture 6b de cette pièce intermédiaire 6 est destinée à être ajustée sur une portée circulaire du pont de balancier, coaxiale à l'axe de pivotement de l'arbre du balancier, pour permettre le réglage du repère comme on le verra par la suite. Cette pièce intermédiaire 6 sert donc d'organe de positionnement angulaire du régulateur balancier-spiral.The Figures 9 to 12 illustrate a first variant of a first embodiment, wherein the connecting member 2 comprises at least two positioning elements and corresponding bearing surfaces. We recognize on the figure 9 a spiral spring 1 similar to that illustrated by the figure 1 . Two fixing pins 5 are intended to pass through the openings 4 of the connecting member 2 and to be driven into corresponding openings 6a made in an intermediate piece 6, provided with an opening 6b concentric with the central axis of the shell 3 after assembly of the elements of the figure 9 . The opening 6b of this intermediate piece 6 is intended to be fitted over a circular bearing surface of the balance bridge, coaxial with the axis of pivoting of the balance shaft, to allow the adjustment of the marker as will be seen later. . This intermediate piece 6 thus serves as angular positioning member of the sprung-balance regulator.

La figure 10 montre l'étape d'assemblage consécutive à la figure 9. L'organe de positionnement angulaire 6 est monté pivotant autour du pont de balancier 9, et est fixé à celui-ci via deux vis 13 traversant une plaquette de serrage 12 d'une part, deux découpes oblongues 9a du pont de balancier 9 d'autre part, pour venir se visser dans deux trous taraudés 6c de l'organe de positionnement angulaire 6. La plaquette de serrage 12 est ici de forme arquée et est montée sur la planche du pont de balancier 9. L'arbre de pivotement du balancier 10a et le balancier 10b peuvent être assemblés au spiral avant ou après le montage de la pièce intermédiaire 6.The figure 10 shows the assembly step following the figure 9 . The angular positioning member 6 is pivotally mounted around the balance bridge 9, and is fixed thereto via two screws 13 passing through a clamping plate 12 on the one hand, two oblong cutouts 9a of the balance bridge 9 of FIG. secondly, to be screwed into two tapped holes 6c of the angular positioning member 6. The clamping plate 12 is here of arcuate shape and is mounted on the board of the balance bridge 9. The pivot shaft of the balance 10a and the balance 10b can be assembled to the hairspring before or after the mounting of the intermediate piece 6.

La figure 11 montre l'état assemblé de cette première variante. Le réglage du repère de l'organe régulateur balancier-spiral 10 peut s'effectuer en desserrant légèrement les deux vis 13, puis en pivotant l'ensemble solidaire constitué du spiral 1 dont l'extrémité interne est solidaire de l'arbre 10a du balancier-spiral 10, de l'organe de positionnement angulaire 6, et de la plaquette de serrage 12.The figure 11 shows the assembled state of this first variant. The adjustment of the mark of the balance spring-balance regulator member 10 can be effected by slightly loosening the two screws 13, then by pivoting the integral assembly consisting of the spring 1 whose inner end is integral with the balance shaft 10 a -spiral 10, the angular positioning member 6, and the clamping plate 12.

La figure 12 montre une coupe de la figure 11, permettant de voir la manière dont l'organe de positionnement angulaire 6 est monté pivotant via son ouverture 6b autour d'une portée cylindrique 9b du pont de balancier 9.The figure 12 shows a section of the figure 11 , allowing to see how the angular positioning member 6 is pivotally mounted via its opening 6b around a cylindrical surface 9b of the balance bridge 9.

Les figures 13 et 14 illustrent une deuxième variante de la première forme d'exécution. Le ressort spiral 1 utilisé correspond à celui illustré par la figure 1. Il comporte un organe de liaison 2 s'étendant sur environ 180° autour de l'axe de pivotement de l'arbre de balancier, dont les extrémités sont fixées à l'organe de positionnement angulaire 6 monté pivotant sous le pont de balancier 9 autour du palier 11 de pivotement de l'une des extrémités de l'arbre de balancier. La figure 13 montre cet organe de positionnement angulaire 6 et la figure 14 montre les mêmes éléments que la figure 13, mais après fixation d'une plaquette 12 à cet organe de positionnement angulaire 6 par deux vis 13. La plaquette 12 et l'organe de positionnement angulaire 6 sont donc montés à friction autour du palier 11, permettant d'effectuer le réglage du repère de manière traditionnelle, comme avec un porte piton standard.The Figures 13 and 14 illustrate a second variant of the first embodiment. The spiral spring 1 used corresponds to the one illustrated by the figure 1 . It comprises a connecting member 2 extending about 180 ° about the pivot axis of the balance shaft, whose ends are fixed to the angular positioning member 6 pivotally mounted under the balance bridge 9 around bearing 11 pivoting one of the ends of the balance shaft. The figure 13 shows this angular positioning member 6 and the figure 14 shows the same elements as the figure 13 but after attachment of a plate 12 to this angular positioning member 6 by two screws 13. The plate 12 and the angular positioning member 6 are mounted frictionally around the bearing 11, to perform the setting of the benchmark in a traditional way, as with a standard piton door.

Les figures 15 et 16 illustrent une troisième variante de la première forme d'exécution dans laquelle l'organe de positionnement angulaire 6 porte une goupille à portée 14 qui permet une fixation provisoire de l'organe régulateur balancier-spiral 10 dans une ouverture 9c de fixation à baïonnette ménagée dans la planche du pont de balancier 9, comme illustré par la figure 15. Ensuite, un clinquant 15 est mis en place avec une de ses extrémités entre la planche du pont de balancier 9 et la portée de la goupille 14, alors que son autre extrémité est située entre la planche du pont 9 et la tête d'une vis à portée unique 16 qui est vissée en butée contre l'organe de positionnement angulaire 6, permettant de générer un couple de friction suffisant pour le maintien de l'organe de liaison 2 tout en permettant d'effectuer un réglage aisé de la mise au repère de l'organe régulateur balancier-spiral 10.The Figures 15 and 16 illustrate a third variant of the first embodiment in which the angular positioning member 6 carries a pin 14 which allows a temporary fixing of the sprung balance regulator member 10 in a bayonet attachment opening 9c in the board of the pendulum bridge 9, as illustrated by the figure 15 . Then, a foil 15 is set up with one of its ends between the board of the pendulum bridge 9 and the scope of the pin 14, while its other end is located between the board of the bridge 9 and the head of a screw single-range 16 which is screwed in abutment against the angular positioning member 6, for generating a sufficient friction torque for holding the connecting member 2 while allowing easy adjustment of the setting benchmark of the spring balance regulator 10.

Les figures 17 à 19 illustrent une quatrième variante de la première forme d'exécution, particulièrement adaptée au montage d'un double spiral dont les extrémités externes des lames sont solidaires d'un organe de liaison 2 en forme d'anneau, dans ce cas précis d'anneau ouvert.The Figures 17 to 19 illustrate a fourth variant of the first embodiment, particularly suitable for mounting a double spiral whose outer ends of The blades are secured to a connecting member 2 in the form of a ring, in this case an open ring.

La figure 17 illustre une première étape d'assemblage. Le spiral 1 est ici solidarisé au support de spiral 17 par trois goupilles 5 qui traversent les ouvertures 4 du spiral 1 pour être chassées dans les ouvertures 17c de la pièce intermédiaire 17.The figure 17 illustrates a first assembly step. The spiral 1 is here secured to the spiral support 17 by three pins 5 which pass through the openings 4 of the spiral 1 to be driven into the openings 17c of the intermediate part 17.

Les points de fixation peuvent être de simples trous de positionnement circulaires 4 réalisés dans l'anneau que forme l'organe de liaison 2. En variante, les trous de positionnement 4 de l'organe de liaison 2 pourraient intégrer des bras flexibles (non représentés) pour un bon positionnement, ou présenter un contour ouvert à l'instar d'une virole fendue avec une certaine élasticité, formant ainsi des bras élastiques de manière à assurer un serrage autour des goupilles 5.The attachment points may be simple circular positioning holes 4 made in the ring formed by the connecting member 2. Alternatively, the positioning holes 4 of the connecting member 2 could incorporate flexible arms (not shown ) for a good positioning, or present an open contour like a split ferrule with a certain elasticity, thus forming elastic arms so as to ensure a clamping around the pins 5.

La figure 18 illustre une seconde étape d'assemblage. Le support de spiral 17 muni du ressort spiral 1 est relié au pont de balancier 9 par l'organe de positionnement angulaire 6, par le biais de deux vis 13 traversant des ouvertures 6d de l'organe 6 et vissées dans les trous taraudés 17a du support 17. Le bon positionnement de l'ensemble se fait grâce au dépassement des goupilles 5 qui se logent dans des ouvertures ajustées 6e de l'organe 6.The figure 18 illustrates a second assembly step. The spiral support 17 provided with the spiral spring 1 is connected to the balance bridge 9 by the angular positioning member 6, by means of two screws 13 passing through openings 6d of the member 6 and screwed into the threaded holes 17a of the support 17. The good positioning of the assembly is achieved by exceeding the pins 5 which are housed in fitted openings 6e of the body 6.

La figure 19 illustre l'assemblage complet. On constate ici que l'organe de positionnement angulaire 6 est muni d'une bague 6b présentant une fente 6c qui permet, par friction autour du palier 11 de l'arbre de balancier, solidaire du pont de balancier 9, le positionnement angulaire de l'organe régulateur et donc un réglage aisé du repère.The figure 19 illustrates the complete assembly. It can be seen here that the angular positioning member 6 is provided with a ring 6b having a slot 6c which, by friction around the bearing 11 of the balance shaft, integral with the balance bridge 9, the angular positioning of the regulating organ and therefore easy adjustment of the marker.

Les tolérances de fabrication du support de spiral 17 étant plus larges que celles du ressort spiral 1, on pourra ajuster le jeu au niveau de chaque fixation 17c pour garantir la tenue la plus précise possible sans pour autant sur-contraindre le système et le rendre hyperstatique. Un choix possible pour garantir un bon assemblage est de laisser plus de jeu au niveau du point de fixation intermédiaire 17c', qui présentera alors un diamètre plus important que les autres pour absorber les différentes erreurs dues aux tolérances de fabrication des autres composants. Une alternative consiste à définir les jeux de tous les points d'attache en fonction des tolérances de la pièce rigide.Since the manufacturing tolerances of the spiral support 17 are wider than those of the spiral spring 1, the clearance can be adjusted at the level of each fastener 17c to guarantee the most precise possible holding without over-constraining the system and make it hyperstatic. A possible choice to ensure a good assembly is to leave more play at the intermediate attachment point 17c ', which will then have a greater diameter than the others to absorb the various errors due to manufacturing tolerances of other components. An alternative is to define the sets of all attachment points according to the tolerances of the rigid part.

La face inférieure du support de spiral 17 présente un dégagement 17e pour éviter le frottement avec le ressort spiral. Les bras 17d du support 17 servent de butée aux déformations du spiral 1 sous l'effet d'un choc.The lower face of the spiral support 17 has a clearance 17e to avoid friction with the spiral spring. The arms 17d of the support 17 serve as a stop to the deformations of the spring 1 under the effect of an impact.

Une deuxième forme d'exécution est illustrée par les figures 20 à 22. Cette solution utilise le ressort spiral de la figure 8, mais convient aussi à tout autre ressort spiral muni d'un organe de liaison 2 similaire. Elle consiste à pincer axialement l'organe de liaison annulaire 2 plus rigide entre une pièce de fixation intermédiaire 7, munie d'une noyure de positionnement 7a (figure 22) pour recevoir l'organe de liaison annulaire 2, et le pont de balancier ou un organe de positionnement angulaire. Cette noyure de positionnement 7a permet la mise au repère de l'organe régulateur balancier-spiral, lorsque l'extrémité interne du spiral est assemblée à l'arbre du balancier. Deux vis de fixation 13 permettent de serrer l'organe de liaison annulaire 2 entre le pont de balancier 9 et la pièce de fixation intermédiaire 7, la profondeur de la noyure 7a ménagée dans la pièce de fixation intermédiaire 7 étant inférieure de quelques centièmes de millimètres à l'épaisseur de l'organe de liaison annulaire 2 (figure 22).A second embodiment is illustrated by the Figures 20 to 22 . This solution uses the spiral spring of the figure 8 but is also suitable for any other spiral spring provided with a similar connecting member 2. It consists in pinching axially the more rigid annular connecting member 2 between an intermediate fastening piece 7, provided with a positioning hole 7a ( figure 22 ) to receive the annular connecting member 2, and the pendulum bridge or an angular positioning member. This positioning wedge 7a makes it possible to set the reference point of the balance-sprung regulator member, when the inner end of the balance spring is assembled to the balance shaft. Two fastening screws 13 make it possible to tighten the annular connecting member 2 between the rocker bridge 9 and the intermediate fastener piece 7, the depth of the hole 7a formed in the intermediate fastening piece 7 being less than a few hundredths of a millimeter. to the thickness of the annular connecting member 2 ( figure 22 ).

Il n'y a alors pas au moins deux points de fixation ou de pitonnage discrets, mais une fixation sur une surface d'appui s'étendant sur un arc de cercle d'au moins 60°. Cette solution permet un réglage aisé du repère et facilite les opérations de vérification et d'assemblage. En effet, aucun élément ne recouvre le ressort spiral, et toutes les spires du ressort sont alors visibles.There are then not at least two discrete fixing or pegging points, but a fixation on a surface support extending over an arc of at least 60 °. This solution allows easy adjustment of the marker and facilitates verification and assembly operations. Indeed, no element covers the spiral spring, and all turns of the spring are then visible.

Une troisième forme d'exécution consiste à ménager des bras élastiques 2a séparant deux parties de l'organe de liaison annulaire 2, ce qui permet, dans la variante illustrée aux figures 23 et 24, de clipser l'organe de liaison annulaire 2 autour de goupilles 16 chassées dans le pont de balancier 9, le centrage étant assuré par deux éléments de positionnement 4b (découpes de centrage) pratiqués dans l'organe de liaison 2. La surface d'appui s'étend sur un arc de cercle d'au moins 60°.A third embodiment consists in providing resilient arms 2a separating two parts of the annular connecting member 2, which allows, in the variant illustrated in FIGS. Figures 23 and 24 , clipping the annular connecting member 2 about pins 16 driven in the balance bridge 9, the centering being provided by two positioning elements 4b (centering cuts) formed in the connecting member 2. The surface of support extends over an arc of at least 60 °.

Une quatrième forme d'exécution, proche de la précédente, consiste à ménager, en plus ou au lieu des bras élastiques 2a, des bras élastiques 2c dans le bord de l'organe de liaison annulaire 2 (figures 25 et 26) pour permettre de clipser l'anneau dans des logements 17 ménagés à cet effet dans le pont de balancier 9. Le réglage du repère peut être effectué en modifiant la position angulaire du spiral, par exemple à l'aide d'outils qui viennent s'insérer dans des passages 2d ménagés dans l'organe de liaison 2.A fourth embodiment, close to the previous one, consists in providing, in addition to or instead of elastic arms 2a, resilient arms 2c in the edge of the annular connecting member 2 ( Figures 25 and 26 ) to allow clipping of the ring in housings 17 provided for this purpose in the balance bridge 9. The setting of the marker can be performed by changing the angular position of the spiral, for example using tools that come s insert in passages 2d formed in the connecting member 2.

Ces différentes caractéristiques, notamment les différentes caractéristiques des différentes formes d'exécution, et/ou ces différentes formes d'exécution peuvent, sauf incompatibilité, être combinées les unes aux autres.These different characteristics, in particular the different characteristics of the various embodiments, and / or these different embodiments may, unless they are incompatible, be combined with each other.
