ART ANTÉRIEURPRIOR ART

Dans une montre mécanique, il est d'usage d'utiliser un organe régulateur comportant un dispositif à balancier-spiral. De façon classique, l'extrémité interne du spiral est fixée à une virole prévue sur l'axe de pivotement du balancier. Afin de fixer et positionner l'extrémité extérieure du spiral, il est connu d'utiliser un porte-piton logeant un piton, en association avec une vis de serrage permettant de serrer le piton contre la portion du spiral engagée dans le porte-piton.In a mechanical watch, it is customary to use a regulating member comprising a sprung balance device. Conventionally, the inner end of the hairspring is fixed to a ferrule provided on the axis of pivoting of the balance. In order to fix and position the outer end of the hairspring, it is known to use a peg holder housing a pin, in combination with a clamping screw for tightening the bolt against the portion of the hairspring engaged in the bolt carrier.

Dans un tel ensemble, comme dans le document CH 609 515 , le porte-piton est classiquement fixé à un coq servant également à fixer une des extrémités de l'axe du balancier. En pratique, lors du montage et/ou du réglage, les manipulations à effectuer avec ces différents éléments sont délicates, car l'accès est restreint et les pièces sont de très petites dimensions. En outre, avec de telles configurations, il est courant que la vis de serrage du spiral ou le porte-piton se détache, et/ou soit perdu lors d'une manipulation telle que l'ajustement de la longueur active du spiral.In such a set, as in the document CH 609 515 , the peg carrier is conventionally attached to a cock also serving to fix one of the ends of the axis of the balance. In practice, during assembly and / or adjustment, the manipulations to be performed with these various elements are delicate because access is restricted and the parts are very small. In addition, with such configurations, it is common for the spiral clamping screw or peg holder to come loose, and / or be lost during handling such as adjusting the active length of the hairspring.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

La présente invention procède de l'idée générale de fournir un ensemble de maintien ou d'appui d'un ressort spiral d'horlogerie permettant un montage/démontage du piton plus simple.The present invention proceeds from the general idea of providing a support or support assembly of a spiral clock spring for mounting / dismounting of the simplest piton.

Dans un premier mode de réalisation visible à la figure 1 est représentée une vue schématique d'un ensemble de maintien ou d'appui 1 d'un ressort spiral d'horlogerie selon un premier mode de réalisation. Cet ensemble de maintien 1 comporte un porte-piton 3 agencé pour être fixé au pont de balancier 5 aussi appelé coq ou base, ce dernier comprend un axe longitudinal (D). L'ensemble de maintien comporte également un piton 9 fixé sur une spire du ressort spiral. Le porte-piton 3 est utilisé pour la fixation du piton au coq.In a first embodiment visible at the figure 1 is shown a schematic view of a holding or support assembly 1 a spiral spring clock according to a first embodiment. This holding assembly 1 comprises a bolt carrier 3 arranged to be fixed to the balance bridge 5 also called cock or base, the latter comprises a longitudinal axis (D). The holding assembly also comprises a pin 9 fixed on a turn of the spiral spring. The bolt carrier 3 is used for fixing the stud to the cock.

Dans ce premier mode de réalisation visible aux figures 1 et 2, le porte-piton 3 se compose d'une plaque de maintien 32. Le pont de balancier 5 comporte un plot 31 faisant saillie. Cette plaque de maintien 32 est une plaque percée par un orifice 34. La plaque de maintien 32 comprend en outre une poutre déformable 35 séparant l'orifice 34 en une première ouverture 34a et une seconde ouverture 34b.In this first embodiment visible to Figures 1 and 2 , the bolt carrier 3 consists of a retaining plate 32. The pendulum bridge 5 comprises a stud 31 projecting. This holding plate 32 is a plate pierced by an orifice 34. The holding plate 32 further comprises a deformable beam 35 separating the orifice 34 in a first opening 34a and a second opening 34b.

La première ouverture 34b est la partie la plus importante et est agencée pour coopérer avec le plot 31. On entend par là que le plot 31 s'insère dans la première ouverture 34a. La seconde ouverture 34b est utilisée pour le piton 9. En effet, le piton 9 s'insère dans la seconde ouverture 34b.The first opening 34b is the largest part and is arranged to cooperate with the pad 31. This means that the stud 31 is inserted into the first opening 34a. The second opening 34b is used for the piton 9. Indeed, the pin 9 fits into the second opening 34b.

Avantageusement selon l'invention, la forme du plot 31 et celle de la première ouverture 34a sont telles qu'elles permettent, lors de la rotation de la plaque de maintien par rapport audit plot, d'agir sur la poutre déformable 35. Cette déformation de ladite poutre permet de rétrécir la seconde ouverture 34b et donc de serrer le piton.Advantageously according to the invention, the shape of the stud 31 and that of the first opening 34a are such that, when the holding plate is rotated relative to said stud, it acts on the deformable beam 35. This deformation said beam allows to narrow the second opening 34b and thus to tighten the peak.

Dans une première solution visible aux figures 3a, 3b et 3c, la première partie 34a est conçue pour avoir une forme parfaitement circulaire, la seconde partie 34b se présentant sous la forme d'une rainure courbe. Dans cette première solution, le plot 31 se présente sous la forme d'une pièce de section non constante. Plus particulièrement, on réalisera le plot 31 de sorte que celui-ci se présente sous la forme d'une pièce sensiblement circulaire ayant un axe central C dont une zone présente une distance entre le centre du cercle et l'extrémité du plot 31 plus grande ce qui permet d'avoir une zone distincte comme visible à la figure 3a.In a first solution visible to Figures 3a, 3b and 3c the first portion 34a is designed to have a perfectly circular shape, the second portion 34b being in the form of a curved groove. In this first solution, the stud 31 is in the form of a piece of non-constant section. More particularly, the pad 31 will be made so that it is in the form of a substantially circular piece having a central axis C whose area has a distance between the center of the circle and the end of the stud 31 larger which allows to have a separate area as visible in the figure 3a .

Cette zone distincte sera utilisée pour le serrage du piton 9. En effet, en faisant pivoter la plaque de maintien 32 par rapport au plot 31, la zone distincte du plot 31 va entrer en contact de la poutre déformable 35. Etant donné que la première ouverture 34a est circulaire, la zone distincte du plot 31 exerce une contrainte sur cette poutre déformable 35. Cette contrainte déforme ainsi la poutre 35 qui rétrécit la seconde ouverture 34b. Ce rétrécissement entraîne une contrainte exercée sur le piton 9 afin de le serrer.This distinct zone will be used for the clamping of the pin 9. Indeed, by rotating the holding plate 32 relative to the stud 31, the distinct area of the stud 31 will come into contact with the deformable beam 35. Since the first aperture 34a is circular, the distinct area of the stud 31 exerts a stress on this deformable beam 35. This constraint thus deforms the beam 35 which narrows the second opening 34b. This narrowing causes a constraint exerted on the pin 9 to tighten it.

Pour le montage, celui-ci se fait en montant la plaque 32 au niveau du coq 5 en insérant le plot 31 dans la première ouverture 34a de la plaque de maintien 32. La plaque de maintien 32 pourra être montée dans sa position angulaire définitive ou pas. Le plot 31 pourra être muni d'une rainure périphérique empêchant la plaque de maintien 32 de se désolidariser. Dans le cas où la plaque de maintien 32 est montée dans sa position angulaire définitive, la plaque de maintien 32 sera pivotée d'un certain angle dans le sens horaire ou antihoraire de sorte que la zone distincte ne soit plus en contact avec la poutre déformable 35. La contrainte appliquée par cette zone distincte est donc retirée et la seconde ouverture 34b reprend sa taille de repos comme visible à la figure 3b.For mounting, it is done by mounting the plate 32 at the cock 5 by inserting the stud 31 in the first opening 34a of the holding plate 32. The holding plate 32 can be mounted in its final angular position or not. The stud 31 may be provided with a peripheral groove preventing the holding plate 32 from being detached. In the case where the holding plate 32 is mounted in its final angular position, the holding plate 32 will be rotated by a certain angle in the clockwise or counterclockwise direction so that the distinct zone is no longer in contact with the deformable beam. 35. The stress applied by this distinct zone is thus removed and the second opening 34b resumes its rest size as visible at the figure 3b .

Le piton 9 est alors placé dans la seconde ouverture 34b puis la plaque de maintien 32 est mise en rotation par rapport au plot 31 pour rétrécir la seconde ouverture 34b et serrer le piton 9 sur la plaque de maintien 32 comme visible à la figure 3c.The pin 9 is then placed in the second opening 34b and the holding plate 32 is rotated relative to the stud 31 to narrow the second opening 34b and tighten the pin 9 on the holding plate 32 as visible in FIG. figure 3c .

Le plot 31 pourra être conçu comme étant une pièce circulaire munie d'une partie saillante ou d'une pièce de forme ovoïdale.The stud 31 may be designed as a circular piece provided with a projecting portion or an ovoid-shaped piece.

Dans une seconde solution visible aux figures 4 et 5, la première ouverture 34a est conçue pour avoir une forme d'ellipse, la seconde ouverture 34b se présentant sous la forme d'une rainure courbe. Une telle forme d'ellipse permet d'avoir un plot 31 elliptique. Une telle ellipse présente un axe principal appelé axe focal passant par les foyers et un axe secondaire perpendiculaire à l'axe focal et passant au centre du segment formé par les deux points focaux de ladite ellipse. Dans cette seconde solution, le plot 31 se présente sous la forme d'une pièce de section identique à celle de la première ouverture 34a comme visible à la figure 4.In a second solution visible to Figures 4 and 5 the first opening 34a is designed to have an elliptical shape, the second opening 34b being in the form of a curved groove. Such a elliptical shape allows to have an elliptical stud 31. Such an ellipse has a main axis called focal axis passing through the foci and a secondary axis perpendicular to the focal axis and passing to the center of the segment formed by the two focal points of said ellipse. In this second solution, the stud 31 is in the form of a piece of section identical to that of the first opening 34a as visible in FIG. figure 4 .

Toutefois, le plot 31 est agencé de sorte que son axe principal s'étende parallèlement à l'axe longitudinal du coq (5) comme visible à la figure 4. Par conséquent, lors du montage de la plaque de maintien 32, le plot 31 est inséré dans la première ouverture 34a. Le résultat est que la plaque de maintien 32 se trouve dans une position angulairement décalée par rapport à un alignement avec l'axe longitudinal du coq 5. Cela est dû au fait que lorsque la plaque 32 et le coq 5 sont parfaitement alignés, le plot 31 et la première ouverture 34a de la plaque 32, qui ont une forme identique, ne sont pas confondus et sont décalés angulairement.However, the stud 31 is arranged so that its main axis extends parallel to the longitudinal axis of the cock (5) as visible in FIG. figure 4 . Therefore, when mounting the holding plate 32, the stud 31 is inserted into the first opening 34a. The result is that the holding plate 32 is in a position angularly offset relative to an alignment with the longitudinal axis of the cock 5. This is because when the plate 32 and the cock 5 are perfectly aligned, the stud 31 and the first opening 34a of the plate 32, which have an identical shape, are not confused and are angularly offset.

Lors de la rotation de la plaque de maintien 32 pour effectuer le serrage du piton 9 inséré dans la seconde ouverture 34b, un des deux pôles c'est-à-dire une des deux zones les plus éloignées du centre du plot 31 entre en contact avec la poutre déformable 35. Cette poutre déformable 35 subit alors une contrainte de la part du plot 31 entraînant la déformation de ladite poutre 35. Cette déformation de ladite poutre 35 entraîne un rétrécissement de la seconde ouverture 34b et donc l'apparition d'une contrainte sur le piton 9 qui le serre comme visible à la figure 5.During rotation of the holding plate 32 to effect the clamping of the stud 9 inserted in the second opening 34b, one of the two poles, that is to say one of the two furthest regions from the center of the stud 31 comes into contact with the deformable beam 35. This deformable beam 35 then undergoes a constraint on the part of the stud 31 causing the deformation of said beam 35. This deformation of said beam 35 causes a narrowing of the second opening 34b and therefore the appearance of a constraint on the piton 9 which squeezes it as visible at the figure 5 .

Dans un second mode de réalisation visible à la figure 6, le porte-piton 3 se compose d'une plaque de maintien 302 et d'un plot 301. La plaque de maintien et le coq ne sont ici qu'une seule pièce dans laquelle un orifice 304 est réalisé. Le plot 301 est ici une pièce libre venant coopérer avec ladite plaque de maintien.In a second embodiment visible at the figure 6 , the bolt carrier 3 consists of a holding plate 302 and a stud 301. The holding plate and the cock are here only one piece in which an orifice 304 is made. The stud 301 is here a free piece cooperating with said holding plate.

La plaque de maintien 302 comprend en outre une poutre déformable 305 séparant l'orifice 304 en une première ouverture 304a et une seconde ouverture 304b. La première ouverture 304b est la partie la plus importante et est agencée pour coopérer avec le plot 301. On entend par là que le plot 301 s'insère dans la première ouverture 304a. La seconde ouverture 304b est utilisée pour le piton 9. En effet, le piton 9 s'insère dans la seconde ouverture 304b.The holding plate 302 further comprises a deformable beam 305 separating the orifice 304 into a first opening 304a and a second opening 304b. The first opening 304b is the largest part and is arranged to cooperate with the stud 301. This means that the stud 301 is inserted into the first opening 304a. The second opening 304b is used for the piton 9. Indeed, the stud 9 fits into the second opening 304b.

Avantageusement selon l'invention, la forme du plot 302 et celle de la première ouverture 304a sont telles qu'elles permettent, lors de la rotation du plot 302 par rapport à la plaque de maintien, d'agir sur la poutre déformable 305. Cette déformation de ladite poutre permet de rétrécir la seconde ouverture 34b et donc de serrer le piton 9.Advantageously according to the invention, the shape of the stud 302 and that of the first opening 304a are such that, when the stud 302 is rotated relative to the holding plate, it acts on the deformable beam 305. deformation of said beam makes it possible to narrow the second opening 34b and thus to tighten the bolt 9.

Dans une première solution visible aux figures 7a et 7b, la première ouverture 304a est conçue pour avoir une forme parfaitement circulaire, la seconde ouverture 304b se présentant sous la forme d'une rainure courbe. Dans cette première solution, le plot 301 se présente sous la forme d'une pièce de section non constante. Plus particulièrement, on réalisera le plot 301 de sorte que celui-ci se présente sous la forme d'une pièce sensiblement circulaire dont une zone présente une distance entre le centre du cercle et l'extrémité du plot 301, plus grande ce qui permet d'avoir une zone distincte.In a first solution visible to Figures 7a and 7b the first opening 304a is designed to have a perfectly circular shape, the second opening 304b being in the form of a curved groove. In this first solution, the stud 301 is in the form of a piece of non-constant section. More particularly, the stud 301 will be made so that it is in the form of a substantially circular piece whose area has a distance between the center of the circle and the end of the stud 301, which makes it possible to have a separate area.

Cette zone distincte sera utilisée pour le serrage du piton 9. En effet, en faisant pivoter le plot 301 par rapport à la plaque de maintien 302, la zone distincte du plot 301 va entrer en contact de la poutre déformable 305. Etant donné que la première ouverture 304a est circulaire, la zone distincte du plot 301 exerce une contrainte sur cette poutre déformable 305. Cette contrainte déforme ainsi la poutre 305 qui rétrécit la seconde ouverture 304b. Ce rétrécissement entraine une contrainte exercée sur le piton 9 afin de le serrer.This distinct zone will be used for the clamping of the pin 9. Indeed, by rotating the stud 301 with respect to the holding plate 302, the distinct zone of the stud 301 will come into contact with the deformable beam 305. Since the first opening 304a is circular, the distinct zone of the stud 301 exerts a stress on this deformable beam 305. This constraint thus deforms the beam 305 which narrows the second opening 304b. This narrowing causes a constraint exerted on the pin 9 to tighten it.

Pour le montage, celui-ci se fait en montant le plot 301 au niveau du coq 5 en l'insérant dans la première ouverture 304a de la plaque de maintien 302. Le plot 301 pourra être monté dans sa position angulaire définitive ou pas. Dans le cas où le plot 301 est monté dans sa position angulaire définitive, le plot 301 sera pivoté d'un certain angle dans le sens horaire ou antihoraire de sorte que la zone distincte ne soit plus en contact avec la poutre déformable 305. La contrainte appliquée par cette zone distincte est donc retirée et la seconde ouverture 304b reprend sa taille de repos permettant le montage du piton 9.For mounting, it is done by mounting the stud 301 at the cock 5 by inserting it into the first opening 304a of the holding plate 302. The stud 301 can be mounted in its angular position definitive or not. In the case where the stud 301 is mounted in its final angular position, the stud 301 will be rotated by a certain angle in the clockwise or counterclockwise direction so that the distinct zone is no longer in contact with the deformable beam 305. The constraint applied by this distinct zone is removed and the second opening 304b resumes its rest size allowing mounting of the peak 9.

Le piton 9 est alors placé dans la seconde ouverture 304b puis le plot 301 est mis en rotation par rapport à la plaque de maintien 302 pour rétrécir la seconde ouverture 304b et serrer le piton 9 sur la plaque de maintien 302.The stud 9 is then placed in the second opening 304b and the stud 301 is rotated relative to the holding plate 302 to narrow the second opening 304b and tighten the stud 9 on the holding plate 302.

Le plot 301 pourra être conçu comme étant une pièce circulaire muni d'une ouverture saillante ou d'une pièce de forme ovoïdale.The stud 301 may be designed as a circular piece provided with a projecting opening or a piece of ovoid shape.

Il est possible de régler la position angulaire du piton 9 en le faisant coulisser dans la seconde ouverture 304b.It is possible to adjust the angular position of the pin 9 by sliding it in the second opening 304b.

Dans une seconde solution visible aux figures 8a, 8b et 8c, la première ouverture 304a est conçue pour avoir une forme parfaitement ovoïdale, la seconde ouverture 304b se présentant sous la forme d'une rainure courbe. Une telle forme ovoïdale permet d'avoir un plot 301 dont les dimensions extérieures dans le plan X-Y sont différentes. La longueur du plot 301 est plus importante que sa largeur. Dans cette seconde solution, le plot 301 se présente sous la forme d'une pièce de section identique à cette de la première ouverture.In a second solution visible to Figures 8a, 8b and 8c the first opening 304a is designed to have a perfectly ovoidal shape, the second opening 304b being in the form of a curved groove. Such an ovoid shape makes it possible to have a stud 301 whose external dimensions in the XY plane are different. The length of the pad 301 is larger than its width. In this second solution, the stud 301 is in the form of a piece of section identical to that of the first opening.

Toutefois, la première ouverture 304a est agencée de sorte que sa longueur s'étende perpendiculairement à l'axe longitudinal du coq (5). Par conséquent, lors du montage de la plaque de maintien 302, le plot 301 est inséré dans la première ouverture. Le résultat est que l'axe longitudinal du plot 301 se trouve dans une position angulairement décalée par rapport à un alignement avec l'axe longitudinal du coq 5.However, the first opening 304a is arranged so that its length extends perpendicularly to the longitudinal axis of the cock (5). Therefore, when mounting the holding plate 302, the stud 301 is inserted into the first opening. The result is that the longitudinal axis of the stud 301 is in a position angularly offset relative to an alignment with the longitudinal axis of the cock 5.

Lors de la rotation du plot 301 pour effectuer le serrage du piton inséré dans la seconde ouverture, un des deux pôles c'est-à-dire une des deux zones les plus éloignées du centre du plot 301 entre en contact avec la poutre déformable 305. Cette poutre déformable 305 subit alors une contrainte de la part du plot 301 entrainant sa déformation. Cette déformation entraine un rétrécissement de la seconde ouverture 304b et donc l'apparition d'une contrainte sur le piton 9 afin de le serrer.During the rotation of the stud 301 to effect the clamping of the stud inserted in the second opening, one of the two poles, that is to say one of the two zones farthest from the center of the stud 301 comes into contact with the deformable beam 305 This deformable beam 305 is then subjected to a stress on the part of the stud 301 causing its deformation. This deformation causes a narrowing of the second opening 304b and therefore the appearance of a constraint on the pin 9 to tighten it.

Dans une variante visible à la figure 9, la plaque de maintien 302 est une plaque venant se fixer sur le coq 5. Le coq 5 comprend également un trou traversant ou non 500 identique à la première ouverture 304a de la plaque de maintien 302. Lorsque la plaque de maintien 302 est fixée au coq 5, les deux ouvertures 304a, 500 se confondent l'une l'autre. Cette variante permet avantageusement de modifier la position angulaire de la plaque de maintien par rapport à celle du coq et ainsi permettre un meilleur positionnement du piton.In a variant visible at the figure 9 , the holding plate 302 is a plate which is fixed on the cock 5. The cock 5 also comprises a through hole or not 500 identical to the first opening 304a of the holding plate 302. When the holding plate 302 is fixed to the cock 5, the two openings 304a, 500 merge with each other. This variant advantageously makes it possible to modify the angular position of the holding plate relative to that of the cock and thus allow a better positioning of the pin.

Pour le montage à rotation du plot 301 par rapport à la plaque de maintien 302 ou de la plaque de maintien 32 par rapport au plot 31, une interface male 700 et une interface femelle 702 sont agencées. L'interface male 700 et l'interface femelle 702 coopèrent ainsi ensemble de manière à permettre à la partie mobile d'être montée au coq 5 par un mouvement de rotation.For the rotational mounting of the stud 301 relative to the holding plate 302 or the holding plate 32 relative to the stud 31, a male interface 700 and a female interface 702 are arranged. The male interface 700 and the female interface 702 thus cooperate together so as to allow the mobile part to be mounted to the cock 5 by a rotational movement.

Selon une première alternative de réalisation, le montage à rotation est un montage à baïonnette. Dans le cas de la figure 13, le plot s'étend depuis le coq 4 et la plaque de maintien 32 est montée au plot 31. L'interface femelle 702 est agencée sur le plot 31. Cette interface femelle 702 consiste en ce que le plot 31 comporte dans son épaisseur, au moins une cavité 702a. Cette cavité 702a est formée par un dégagement 702b parallèle audit axe central du plot 31 et débouchant par rapport à la surface inférieure du plot 31, et, sécante avec ledit premier dégagement et à l'opposé de la surface supérieure 31 a, une gorge borgne 702c. Cette gorge 702c est utilisée pour l'immobilisation en baïonnette de la plaque de maintien 32.According to a first alternative embodiment, the rotational mounting is a bayonet mount. In the case of figure 13 , the pad extends from the cock 4 and the holding plate 32 is mounted on the pad 31. The female interface 702 is arranged on the pad 31. This female interface 702 consists in that the stud 31 has in its thickness, at least one cavity 702a. This cavity 702a is formed by a clearance 702b parallel to said central axis of the stud 31 and opening with respect to the lower surface of the stud 31, and secant with said first clearance and opposite the upper surface 31a, a blind groove 702c. This throat 702c is used for bayonet immobilization of the holding plate 32.

L'interface male 700, située au niveau de la première ouverture 34a, consiste en au moins une partie saillante 701. Cette partie saillante 701 est située sur la tranche de la première ouverture 34a. Cette partie saillante 701 est agencée pour coopérer avec l'interface femelle 702 du plot.The male interface 700, located at the first opening 34a, consists of at least one projecting portion 701. This projecting portion 701 is located on the edge of the first opening 34a. This projecting portion 701 is arranged to cooperate with the female interface 702 of the stud.

La plaque de maintien 32 est montée au niveau du plot 31 de sorte que les parties saillantes 701 de la plaque de maintien 32 puissent s'introduire dans le dégagement 702b dudit plot 31. Le plot peut alors être introduit dans la première ouverture. Lorsque le plot arrive en butée, les parties saillantes doivent se trouver en regard des gorges. Par conséquent, un mouvement de rotation est effectué pour introduire les parties saillantes dans lesdites gorges et fixer ledit plot au coq.The holding plate 32 is mounted at the pad 31 so that the protrusions 701 of the holding plate 32 can be introduced into the clearance 702b of said pad 31. The pad can then be introduced into the first opening. When the stud reaches the stop, the projecting parts must be opposite the grooves. Therefore, a rotational movement is made to introduce the protrusions into said grooves and fix said stud to the cock.

Selon une seconde alternative, le montage à rotation est un montage par vissage. Pour cela, l'interface femelle et l'interface male consistent tous les deux en un pas de vis.According to a second alternative, the rotational mounting is a screw mounting. For this, the female interface and the male interface are both in a thread.

Dans une première variante des deux modes de réalisation visibles aux figures 10 et 11, le plot 31, 301 comprend, au niveau de sa face inférieure 31 a, 301 a, un évidement 400. Cet évidement permet d'y insérer un système amortisseur de chocs 402. Ce dernier peut se présenter sous une forme classique c'est-à-dire un chaton dans lequel une pierre percée et une pierre contre pivot sont agencées ou bien sous la forme d'une pierre unique 404. Cette pierre unique 404 est munie d'un évidement pour coopérer avec l'axe de balancier et peut être montée à force dans l'évidement 400 via une bague élastique 406. Le système amortisseur de chocs pourra également se présenter sous la forme d'une pastille munie de bras élastiques. Cette variante permet d'avoir un centrage entre le piton et le pivot de l'axe de balancier qui va coopérer avec ledit système amortisseur de chocs. Cette variante peut être poussée plus loin en imaginant que le plot 301 est lui-même un système amortisseur de chocs. Ce système amortisseur de chocs se présente sous la forme d'un chaton dans lequel une pierre percée et une pierre contre-pivot sont agencées.In a first variant of the two embodiments visible to the Figures 10 and 11 , the stud 31, 301 comprises, at its lower face 31a, 301a, a recess 400. This recess allows to insert a shock absorber system 402. The latter can be in a conventional form is that is to say a kitten in which a pierced stone and a stone against pivot are arranged or in the form of a single stone 404. This single stone 404 is provided with a recess to cooperate with the balance shaft and can to be force-fitted into the recess 400 via an elastic ring 406. The shock absorbing system may also be in the form of a pellet provided with elastic arms. This variant makes it possible to have a centering between the peak and the pivot of the balance shaft which will cooperate with said shock absorber system. This variant can be pushed further by imagining that the stud 301 is itself a shock absorber system. This shock absorbing system is in the form of a kitten in which a pierced stone and a counter-pivot stone are arranged.

Dans une seconde variante, visible à la figure 12, dans laquelle le plot 301 est une pièce libre et munie d'un système amortisseur de chocs 402, le plot 301 est monté réglable en hauteur. Pour cela, un filetage 600 est agencé au niveau de la première ouverture 304a dans lequel le plot 301 est inséré. Le plot 301 comprend alors un filetage 602 sur sa paroi extérieure 301 b pour coopérer avec le filetage 600 de la plaque de maintien 302. On peut donc ajuster la position en hauteur du système amortisseur de chocs en faisant plus ou moins de tours avec le plot. On comprendra alors qu'une étape préliminaire au montage du piton est une étape de réglage dans laquelle le plot est inséré dans la première ouverture de la plaque de maintien puis mis en rotation pour régler en hauteur le système amortisseur de chocs. L'étape suivante est alors l'étape de mise en place du piton et de serrage de ce piton.In a second variant, visible at figure 12 , in which the stud 301 is a free piece and provided with a shock absorber system 402, the stud 301 is mounted adjustable in height. For this, a thread 600 is arranged at the first opening 304a in which the stud 301 is inserted. The stud 301 then comprises a thread 602 on its outer wall 301b to cooperate with the thread 600 of the holding plate 302. It is therefore possible to adjust the height position of the shock absorber system by making more or less turns with the stud. . It will then be understood that a preliminary step in mounting the stud is a setting step in which the stud is inserted into the first opening of the holding plate and then rotated to adjust the height of the shock absorbing system. The next step is then the step of setting up the peak and tightening this peak.

Dans une troisième variante des premier et second modes de réalisation, des moyens de réglage 800 sont prévus pour le réglage angulaire de la plaque de maintien pour modifier la position angulaire de ladite plaque de maintien par rapport au coq tout en conservant un bon serrage du piton.In a third variant of the first and second embodiments, adjustment means 800 are provided for the angular adjustment of the holding plate to modify the angular position of said holding plate relative to the cock while maintaining a good tightening of the peak .

Dans le cas du second mode de réalisation dans lequel le plot 301 est une pièce qui vient se rapportée sur la base et que la plaque de maintien 302 est fixée au coq 5,
les moyens de réglages 800 comprennent ainsi des moyens d'engagement 801 agencés sur la face de la plaque de maintien en regard du coq et une pluralité de réceptacles 802 agencés sur la face du coq en regard de la plaque de maintien comme visible à la figure 14. Par exemple, les moyens d'engagement 801 comprennent au moins un tube 803 faisant saillie de la face de la plaque de maintien en regard du coq alors que la pluralité de réceptacles comprend une pluralité de trou dans lesquels les tubes peuvent s'insérer. Le fait d'avoir une pluralité de tubes 803 permet d'assurer le maintien même en cas de casse de l'un des tubes 803.In the case of the second embodiment in which the stud 301 is a piece which is attached to the base and the holding plate 302 is fixed to the cock 5,
the adjustment means 800 thus comprise engagement means 801 arranged on the face of the holding plate facing the cock and a plurality of receptacles 802 arranged on the face of the cock facing the holding plate as visible in FIG. figure 14 . For example, the engagement means 801 comprise at least one tube 803 projecting from the face of the holding plate facing the cock while the plurality of receptacles comprises a plurality of holes in which the tubes can fit. The fact of having a plurality of tubes 803 makes it possible to maintain even in case of breakage of one of the tubes 803.

Préférentiellement, la pluralité de tubes et la pluralité de trou sont disposées en cercle. Cet agencement a pour avantage de permettre de modifier angulairement la position de la plaque de maintien par rapport au coq et de verrouiller cette position angulaire. Une fois la position angulaire définie et verrouillée, les étapes de mise en place du piton et de serrage du piton à la plaque de maintien peuvent être opérées.Preferably, the plurality of tubes and the plurality of holes are arranged in a circle. This arrangement has the advantage of allowing angularly change the position of the holding plate relative to the cock and lock this angular position. Once the angular position defined and locked, the steps of setting the stud and clamping the stud to the holding plate can be operated.

Par conséquent, comme le plot est une pièce rapportée, il suffit simplement d'insérer ledit plot dans la première ouverture de la plaque de maintien et dans l'ouverture du coq et de le mettre en rotation pour venir agir sur la poutre déformable de la plaque de maintien pour serrer le piton.Therefore, as the stud is an insert, it suffices simply to insert said stud in the first opening of the holding plate and in the opening of the cock and to rotate it to act on the deformable beam of the holding plate to tighten the piton.

Dans le cas du premier mode de réalisation visible à la figure 17, des moyens de réglage angulaire sont prévus. Ces moyens de réglage 800 comprennent une roue dentée 810 agencée sur le pont de balancier 5. Cette rouée dentée 810 est montée sur un axe. Cette roue dentée 810 est agencée pour coopérer avec une denture 812 agencée sur la plaque de maintien. Plus particulièrement, cette denture 812 est agencée sur la paroi extérieure 32a de la plaque de maintien 32.In the case of the first embodiment visible at the figure 17 angular adjustment means are provided. These adjustment means 800 comprise a toothed wheel 810 arranged on the balance bridge 5. This toothed wheel 810 is mounted on an axis. This toothed wheel 810 is arranged to cooperate with a toothing 812 arranged on the holding plate. More particularly, this toothing 812 is arranged on the outer wall 32a of the holding plate 32.

Cette roue 810 comprend une fente 814 de sorte qu'un outil tel un tournevis à tète plate puis être utilisé pour agir sur la roue dentée 810.This wheel 810 includes a slot 814 so that a tool such as a flat head screwdriver can be used to act on the gear 810.

Ainsi, pour modifier la position angulaire du piton 9 , une personne engage la tête plate du tournevis dans la fente 814 de la roue dentée et met en rotation cette roue dentée 810. Cette roue dentée 810 engrène avec la denture 812 de la plaque de maintien entrainant la rotation de cette dernière.Thus, to change the angular position of the pin 9, a person engages the flat head of the screwdriver in the slot 814 of the toothed wheel and rotates the toothed wheel 810. This toothed wheel 810 meshes with the toothing 812 of the holding plate causing the rotation of the latter.

Il peut être envisagé que les moyens de réglage 800 comprennent une seconde encoche 822 agencée sur la plaque de maintien et une première encoche 820 agencée au niveau du point de balancier 5 comme visible à la figure 18. Ces encoches se trouvent en regard l'une de l'autre de sorte qu'il est possible de placer la tête plate d'un tournevis dans les deux encoches. Cet agencement permet, par pivotement du tournevis 824 sur lui-même, de faire pivoter la plaque de maintien. On obtient ainsi des moyens de réglage angulaire de la plaque de maintien simple et peu coûteux.It can be envisaged that the adjustment means 800 comprise a second notch 822 arranged on the holding plate and a first notch 820 arranged at the pivot point 5 as visible at the figure 18 . These notches are facing each other so that it is possible to place the flat head of a screwdriver in the two notches. This arrangement allows, by pivoting the screwdriver 824 on itself, to rotate the holding plate. Angular adjustment means of the simple and inexpensive holding plate are thus obtained.

Par ailleurs, dans une autre variante, on comprendra que le plot 31 et la plaque de maintien 32 ou la plaque de maintien 302 et le plot 301 soit agencés sur la face inférieure du coq 5 c'est-à-dire au niveau de la face se trouvant en regard du balancier spiral.Furthermore, in another variant, it will be understood that the stud 31 and the holding plate 32 or the holding plate 302 and the stud 301 are arranged on the underside of the cock 5, that is to say at the level of the face lying next to the spiral balance.

Dans une autre variante visible aux figures 15a, 15b, 16a, 16b, l'orifice 34, 304 de la plaque de maintien 32 comme visible aux figures 15a, 15b ou du pont de balancier 5 comme visible aux figures 16a, 16b est séparé en une premier ouverture et une seconde ouverture par un bras déformable 35a, 305a ayant une extrémité reliée à la paroi de l'orifice 34, 304 et une extrémité libre. La paroi de l'orifice 34, 304 comporte en outre une extension 35b, 305b dont la forme est quelconque. Cette extension permet, lors du montage du piton, d'avoir le bras élastique plaquant le piton contre la paroi de la seconde ouverture 34b', 304b' et contre la paroi de l'extension pour bloquer ledit piton comme visible aux figures 15b et 16b.In another variant visible to Figures 15a, 15b, 16a, 16b , the orifice 34, 304 of the holding plate 32 as visible to Figures 15a, 15b or pendulum bridge 5 as visible to Figures 16a, 16b is separated into a first opening and a second opening by a deformable arm 35a, 305a having an end connected to the wall of the orifice 34, 304 and a free end. The wall of the orifice 34, 304 further comprises an extension 35b, 305b whose shape is arbitrary. This extension makes it possible, during mounting of the stud, to have the resilient arm pressing the stud against the wall of the second opening 34b ', 304b' and against the wall of the extension to block said stud as visible to Figures 15b and 16b .

A ce titre, il pourra être prévu une variante dans laquelle le bras déformable comprend une bosse ou saillie 35a' comme visible aux figures 19a, 19b. Cette bosse ou saillie coopère avec le plot 31. En effet, il est astucieusement prévu que le plot 31 soit circulaire mais présente un plat 31 a. Le bras élastique 35a est alors agencé pour que, lorsqu'il se trouve en regard du plat, ledit bras 35a soit relâché afin que le piton puisse y être facilement placé. Lorsque la plaque de maintien 32 est mise en rotation pour verrouiller le piton 9, la bosse du bras élastique 35a reste en contact de la paroi du plot 31 de sorte que la variation d'épaisseur du plot 31 entre le plat et le reste de sa périphérie entraine une contrainte sur le bras élastique 35a. Cette contrainte tend à rapproche le bras élastique de la paroi de l'orifice 34, 304. Le piton est donc maintenu en place par ledit bras élastique. Une encoche 31 b sur ledit plot 31 peut être envisagée pour bloquer la position angulaire de la plaque de maintien 32. Cette configuration permet également de se servir de la bosse comme d'un repère pour visualiser la position angulaire du porte-piton. On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées.As such, it may be provided a variant in which the deformable arm comprises a boss or projection 35a 'as visible at Figures 19a, 19b . This hump or projection cooperates with the stud 31. Indeed, it is cleverly provided that the stud 31 is circular but has a flat 31 a. The elastic arm 35a is then arranged so that, when facing the flat, said arm 35a is released so that the bolt can be easily placed. When the holding plate 32 is rotated to lock the pin 9, the bump of the resilient arm 35a remains in contact with the wall of the stud 31 so that the thickness variation of the stud 31 between the plate and the rest of its periphery causes a constraint on the elastic arm 35a. This constraint tends to bring the elastic arm closer to the wall of the orifice 34, 304. The stud is thus held in place by said elastic arm. A notch 31b on said pad 31 may be considered to block the angular position of the holding plate 32. This configuration also allows to use the bump as a marker to visualize the angular position of the pin holder. It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention set out above without departing from the scope of the invention defined by the appended claims.

Par ailleurs, il peut être prévu que le réglage angulaire de la plaque de maintien sur le coq se fasse en prévoyant deux trous oblongs au niveau de ladite plaque de maintien. Ces deux trous oblongs permettent la fixation de la plaque de maintien sur le coq tout en autorisant un degré de liberté dans la rotation. Préférentiellement, les trous oblongs seront réalisés de sorte que la plaque de maintien puisse se mettre en rotation autour du plot.Furthermore, it can be provided that the angular adjustment of the holding plate on the cock is done by providing two oblong holes at said holding plate. These two oblong holes allow the fixation of the support plate on the cock while allowing a degree of freedom in the rotation. Preferably, the oblong holes will be made so that the holding plate can rotate around the stud.

Il pourra être également prévu que la plaque de maintien 32 soit en outre munie d'au moins une encoche 32a au niveau de sa périphérie comme visible aux figures 19a et 19b. Une telle encoche permet simplement d'utiliser un outil de type tournevis ou brucelles pour mettre en rotation la plaque de maintien. Dans le cas de l'utilisation de brucelles, deux encoches diamétralement opposées peuvent être agencées.It may also be provided that the holding plate 32 is further provided with at least one notch 32a at its periphery as visible at Figures 19a and 19b . Such a notch simply allows to use a screwdriver type tool or tweezers to rotate the holding plate. In the case of the use of tweezers, two diametrically opposed notches can be arranged.

De même, il pourra être prévu que le plot 301 servant d'amortisseur de chocs est utilisé comme butée en Z pour retenir le porte-piton lors des chocs.Similarly, it may be provided that the stud 301 serving as a shock absorber is used as Z stop to retain the bolt carrier during shocks.
