DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne un dispositif régulateur pour pièce d'horlogerie comprenant un balancier inertiel comportant un axe de balancier agencé pour être monté pivotant dans la pièce d'horlogerie, un pont de balancier supportant un palier agencé pour maintenir une extrémité de l'axe de balancier, un spiral comportant une extrémité intérieure solidaire du balancier et une extrémité extérieure solidaire d'un piton, et enfin un mécanisme de fixation du piton comportant un logement porté par le pont de balancier et agencé pour recevoir le piton tout en permettant d'ajuster longitudinalement la position de ce dernier, le mécanisme de fixation comportant encore un bras élastique agencé pour appuyer latéralement sur le piton de manière à immobiliser le piton contre une paroi du logement.The present invention relates to a timepiece control device comprising an inertial balance comprising a balance shaft arranged to be pivotally mounted in the timepiece, a balance bridge supporting a bearing arranged to hold one end of the axis of rotation. balance wheel, a hairspring having an inner end secured to the rocker and an outer end secured to a pin, and finally a piton fixing mechanism comprising a housing carried by the rocker arm and arranged to receive the pin while allowing to adjust longitudinally the position of the latter, the fixing mechanism further comprising an elastic arm arranged to press laterally on the stud so as to immobilize the stud against a wall of the housing.

ART ANTERIEURPRIOR ART

On connait des organes réglant comprenant un balancier et un spiral dont l'extrémité intérieure est fixée rigidement à une virole chassée sur l'axe du balancier, et dont l'extrémité extérieure est fixée rigidement à un piton porté par un porte-piton déplaçable angulairement concentriquement à l'axe du balancier.Regulating members are known comprising a balance and a hairspring whose inner end is fixed rigidly to a hoop driven on the axis of the balance, and whose outer end is fixed rigidly to a pin carried by an angularly displaceable peg holder concentrically to the axis of the balance.

On connait plusieurs manières d'attacher l'extrémité extérieure du ressort spiral à un piton. Une de ces manières est illustrée par les figures 1 et 2 annexées. On introduit d'abord l'extrémité du ressort spiral (référencée 1a) dans une encoche ou un trou que présente le piton 3. Puis le spiral est bloqué dans l'encoche ou le trou par collage. Le piton 3 est ensuite inséré lui-même dans un logement aménagé dans le porte-piton 5. Une petite vis est encore prévue pour immobiliser le piton une fois que sa hauteur à l'intérieur du logement a été ajustée.There are several known ways to attach the outer end of the spiral spring to a peak. One of these ways is illustrated by the figures 1 and 2 attached. We first introduce the end of the spiral spring (referenced 1a) in a notch or a hole that has the peak 3. Then the hairspring is locked in the notch or the hole by gluing. The pin 3 is then inserted itself in a housing arranged in the bolt carrier 5. A small screw is still provided to immobilize the bolt once its height inside the housing has been adjusted.

Le porte-piton est pivoté à frottement dur sur une partie du coq (ou pont de balancier) concentrique à l'axe de balancier. Grâce à cette caractéristique, un horloger peut ajuster la position angulaire du piton et de l'extrémité extérieure du spiral en faisant simplement pivoter le porte-piton par rapport au balancier. Cette manipulation est importante parce que la position angulaire de l'extrémité extérieure du spiral doit être telle que la cheville de plateau soit dans l'axe ancre-balancier lorsque le balancier est dans sa position d'équilibre.The bolt carrier is pivoted to hard friction on a part of the cock (or balance beam) concentric with the balance shaft. With this feature, a watchmaker can adjust the angular position of the stud and the outer end of the hairspring by simply pivoting the bolt carrier relative to the pendulum. This manipulation is important because the angular position of the outer end of the spiral must be such that the plateau pin is in the anchor-balance axis when the balance is in its equilibrium position.

Le réglage de la position du ressort spiral par rapport à l'arbre du balancier doit être précis. En effet, un décentrage du ressort spiral ou encore un défaut de perpendicularité par rapport à l'arbre de balancier 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. En pratique, l'ajustement de la position du piton est délicat, car l'accès est restreint et les pièces concernées sont de très petites dimensions. Avec des ressorts spiraux traditionnels en alliage métallique, une fois l'extrémité externe du spiral fixée au pont de balancier par le piton et le porte-piton, les écarts résiduels par rapport à la forme tridimensionnelle idéale du ressort spiral peuvent encore être corrigés par déformation plastique de l'extrémité du ressort spiral.The adjustment of the position of the spiral spring relative to the balance shaft must be precise. In fact, an off-centering of the spiral spring or a defect of perpendicularity with respect to the balance shaft generates significant chronometric defects, in particular at the level of the isochronism of the regulator. The pin must be perpendicular to the plane of the spiral spring and positioned accurately to ensure a concentric development of the spiral spring. In practice, the adjustment of the position of the peak is delicate because access is restricted and the parts concerned are very small. With traditional metal alloy spiral springs, once the outer end of the balance spring is fixed to the balance bridge by the pin and the bolt carrier, the residual deviations from the ideal three-dimensional shape of the spiral spring can still be corrected by deformation. Plastic end of the spiral spring.

Dans le cas où le ressort spiral est réalisé en un matériau cassant, tel que le silicium, le diamant ou le quartz, un ajustement par déformation plastique comme ci-dessus n'est pas possible. Dans ces conditions, l'utilisation d'un piton impose des tolérances de fabrication très serrées ainsi qu'un assemblage piton-spiral robuste, de manière à obtenir la perpendicularité la plus parfaite possible entre l'axe du piton et le plan du ressort spiral. On comprend sans peine que cet impératif représente une difficulté majeure à l'échelle industrielle, quand on sait que le simple fait d'immobiliser le piton dans son logement par serrage d'une vis peut suffire pour fausser son orientation. De plus, il est courant de faire tomber et d'égarer la vis de serrage pendant l'opération d'ajustement.In the case where the spiral spring is made of a brittle material, such as silicon, diamond or quartz, adjustment by plastic deformation as above is not possible. Under these conditions, the use of a pin imposes very tight manufacturing tolerances as well a robust piton-spiral assembly, so as to obtain the most perfect perpendicularity possible between the axis of the peak and the plane of the spiral spring. It is easy to understand that this imperative represents a major difficulty on an industrial scale, when we know that the simple fact of immobilizing the stud in its housing by tightening a screw can suffice to distort its orientation. In addition, it is common to drop and misplace the clamping screw during the adjustment operation.

Conformément à ce qui précède, un but de la présente invention est de fournir un mécanisme de fixation d'un piton, qui offre la possibilité d'ajuster la position du piton relativement au pont de balancier et d'immobiliser ensuite plus facilement le piton sans avoir recours à une vis. Le document de brevet suisse CH 76'336 décrit un dispositif régulateur à balancier-spiral qui comprend un mécanisme de fixation du piton et qui correspond à la définition donnée en introduction. Selon ce document, le pont de balancier porte un coqueret qui présente une oreille munie d'une encoche latérale faisant office de logement pour le piton. Une fois le piton inséré dans le logement, il est maintenu en place par un ressort fixé au pont de balancier. Le ressort agit en pressant le piton contre le fond de l'encoche de manière à l'immobiliser. Une vis à tête excentrique est encore prévue pour faire s'écarter le ressort du piton de manière à le libérer. Cette solution antérieure présente certains défauts. En particulier, comme le coqueret est monté rigidement sur le pont de balancier, l'orientation de son oreille ne peut pas être changée. La position du logement prévu pour recevoir le piton est donc fixée une fois pour toute. Ainsi, un autre but de la présente invention est donc de fournir un dispositif régulateur à balancier-spiral qui permette également d'ajuster la position du logement dans lequel on immobilise le piton.In accordance with the foregoing, an object of the present invention is to provide a pin attachment mechanism, which offers the possibility of adjusting the position of the stud relative to the balance beam and then immobilize the piton more easily. use a screw. The Swiss patent document CH 76,336 describes a sprung balance regulator device which comprises a piton fixing mechanism and which corresponds to the definition given in the introduction. According to this document, the balance bridge carries a cockpit which has an ear provided with a lateral notch serving as housing for the peak. Once the stud inserted in the housing, it is held in place by a spring attached to the balance bridge. The spring acts by pressing the pin against the bottom of the notch so as to immobilize it. A screw eccentric head is still provided to move the spring of the piton so as to release it. This prior solution has certain defects. In particular, as the cockpit is rigidly mounted on the balance bridge, the orientation of his ear can not be changed. The position of the housing provided to receive the peak is fixed once and for all. Thus, another object of the present invention is therefore to provide a sprung balance regulator device that also allows to adjust the position of the housing in which the pin is immobilized.

BREF EXPOSE DE L'INVENTIONBRIEF SUMMARY OF THE INVENTION

La présente invention atteint ce but en fournissant un régulateur pour pièce d'horlogerie conforme à la revendication 1 annexée.The present invention achieves this goal by providing a timepiece controller in accordance with the appended claim 1.

Grâce à ces caractéristiques, un horloger peut facilement fixer le piton au porte-piton sans avoir recours à une vis, et de plus, il a la possibilité d'ajuster la position angulaire du piton et de l'extrémité extérieure du spiral en faisant simplement pivoter le porte-piton par rapport au balancier, aussi simplement que si le piton était fixé par une vis. En effet, selon l'invention, le bras élastique peut être tourné par rapport au pont de balancier aussi bien que par rapport au porte-piton. Il est donc notamment possible de faire pivoter le bras élastique et le porte-piton de concert.Thanks to these features, a watchmaker can easily attach the bolt to the bolt carrier without using a screw, and in addition, he can adjust the angular position of the bolt and the outer end of the hairspring simply by pivot the bolt carrier relative to the balance, as simply as if the bolt was fixed by a screw. Indeed, according to the invention, the resilient arm can be rotated relative to the balance bridge as well as relative to the bolt carrier. It is therefore particularly possible to rotate the elastic arm and the bolt carrier together.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT

Dans la description qui va suivre, les indications « en dessus » et « en dessous » se réfère à la vue en coupe de la figure 2. Le dessous étant le côté du spiral. D'autre part, l'indication « tourné vers l'extérieur » est à comprendre comme signifiant tourné dans la direction opposée à l'axe du balancier.In the description which follows, the indications "above" and "below" refer to the sectional view of the figure 2 . The underside being the side of the hairspring. On the other hand, the indication "outward facing" is to be understood as meaning turned in the opposite direction to the axis of the balance.

Les figures montrent un organe régulateur à balancier-spiral pour pièce d'horlogerie correspondant à un mode de réalisation particulier de l'invention. En se référant à la figure 1, on peut distinguer le balancier 7 dont l'axe est pivoté entre deux paliers. De manière classique, l'un de ces paliers (référencé 11) est supporté par le pont de balancier (ou coq) 9 par l'intermédiaire d'un coqueret 13, alors que l'autre palier est monté dans la platine (non représentée).

Referring to the figure 1 , one can distinguish the balance 7 whose axis is rotated between two bearings. Conventionally, one of these bearings (referenced 11) is supported by the rocker bridge (or cock) 9 via a cockpit 13, while the other bearing is mounted in the plate (not shown ). Also conventionally, the balance is associated with a hairspring 1 whose central end is fixed to the axis of the balance.

Le coq 9 sert également de support à un ensemble constitué par un piton 3, un porte-piton 5 et un bras élastique 15. Cet ensemble est destiné à positionner l'extrémité extérieure 1 a du spiral 1. Dans le présent exemple, l'extrémité 1 a est d'abord fixée rigidement au piton par collage. Pour ce faire, on introduit d'abord l'extrémité du spiral dans une encoche du piton (non référencée mais visible sur la figure 2). Le spiral est ensuite bloqué dans l'encoche par collage. Précisons que l'invention ne se limite pas à une méthode particulière de fixation de l'extrémité 1 a du spiral sur le piton. L'extrémité 1 a pourrait, tout aussi bien, être par exemple fixée à un piton classique à goupille. Ou, selon une autre variante encore, on pourrait prévoir de réaliser le piton 3 et le spiral 1 de matière en une seule pièce.The cock 9 also serves to support an assembly consisting of a stud 3, a stud holder 5 and an elastic arm 15. This assembly is intended to position the outer end 1a of the spiral 1. In the present example, the end 1a is first fixed rigidly to the stud by gluing. To do this, we first introduce the end of the spiral in a piton notch (not referenced but visible on the figure 2 ). The hairspring is then locked in the notch by gluing. Note that the invention is not limited to a particular method of fixing the end 1a of the spiral on the peak. The end 1 a could, just as well, for example be attached to a conventional bolt pin. Or, according to yet another variant, it is possible to provide the stud 3 and the spiral 1 of material in one piece.

Dans le présent exemple, le porte-piton 5 est essentiellement constitué d'une partie annulaire concentrique à l'axe de balancier, et d'un prolongement en forme de bras (appelé ci-après « oreille ») qui porte le piton 3 et qui s'étend radialement par rapport à l'axe du balancier 7, en direction des spires extérieures du spiral. De manière classique, l'oreille du porte-piton 5 présente un logement 17 orienté parallèlement à l'axe du balancier 7 et dans lequel le piton et inséré longitudinalement. De plus, le porte-piton 5 est pivoté à frottement dur par sa partie annulaire sur le coqueret 13 qui est concentrique au balancier. Grâce à cette caractéristique, un horloger peut modifier la position du piton 3 en faisant simplement pivoter le porte-piton 5 par rapport au coq et au balancier. Précisons encore que le porte-piton est de préférence réalisé en silicium, mais qu'il pourrait aussi être réalisé dans une autre matière. A titre d'exemple, le porte-piton pourrait être réalisé en métal, ou encore en matériau composite. Si le piton est réalisé en métal, il est de préférence formé par dépôt galvanique selon la technique LIGA.In the present example, the bolt carrier 5 essentially consists of an annular portion concentric with the balance shaft, and an arm-shaped extension (hereinafter called "ear") which carries the bolt 3 and which extends radially relative to the axis of the balance 7, towards the outer turns of the spiral. In a classical way, the ear of pin holder 5 has a housing 17 oriented parallel to the axis of the balance 7 and in which the pin and inserted longitudinally. In addition, the bolt carrier 5 is pivoted to hard friction by its annular portion on the brace 13 which is concentric with the pendulum. With this characteristic, a watchmaker can change the position of the stud 3 simply by pivoting the stud holder 5 relative to the cock and the pendulum. It should be noted that the bolt carrier is preferably made of silicon, but that it could also be made of another material. For example, the bolt carrier could be made of metal or composite material. If the peak is made of metal, it is preferably formed by galvanic deposition according to the LIGA technique.

En se référant à nouveau à la figure 1, on peut voir que le logement 17 est formé par un trou traversant formé dans l'oreille du porte-piton 5. On peut voir que, dans l'exemple illustré, le trou traversant présente une section transversale en forme de triangle isocèle ; un des sommets du triangle étant dirigé vers l'axe du balancier. En se référant maintenant à la figure 2, on peut voir que le logement 17 est orienté parallèlement à l'axe du balancier. De plus, le porte-piton 5 présente un rebord 19 qui fait saillie sous la face inférieure de l'oreille. En se référant à la figure, on peut comprendre que le rebord 19 a la forme d'une gorge qui est disposée dans le prolongement de la paroi intérieure du logement 17. Le rebord 19 prolonge donc le logement 17 sous la forme d'une gorge dont le fond est tourné vers l'axe du balancier. Ainsi la longueur totale du logement 17, avec son prolongement, est supérieure à l'épaisseur de l'oreille du porte-piton. Toutefois, la forme de la section transversale du logement au niveau de son prolongement n'est pas celle d'un triangle, mais celle d'un V. L'ouverture de la gorge est orientée en direction de l'extérieur du balancier.Referring again to the figure 1 it can be seen that the housing 17 is formed by a through-hole formed in the ear of the bolt carrier 5. It can be seen that, in the illustrated example, the through-hole has a cross-section in the form of an isosceles triangle; one of the vertices of the triangle being directed towards the axis of the balance. Referring now to the figure 2 it can be seen that the housing 17 is oriented parallel to the axis of the balance. In addition, the peg holder 5 has a flange 19 which protrudes under the underside of the ear. Referring to the figure, it can be understood that the rim 19 has the shape of a groove which is disposed in the extension of the inner wall of the housing 17. The rim 19 thus extends the housing 17 in the form of a groove whose bottom is turned towards the axis of the balance. Thus the total length of the housing 17, with its extension, is greater than the thickness of the ear of the peg carrier. However, the shape of the cross section of the housing at its extension is not that of a triangle, but that of a V. The opening of the groove is oriented towards the outside of the balance.

En se référant à nouveau à la figure 1, on peut voir que la forme ronde du piton 3 ne lui permet pas de venir s'appuyer contre un sommet du triangle (autrement dit, contre le fond de la gorge). Dans l'exemple illustré, le piton est agencé pour venir en appui simultanément contre deux faces de la paroi intérieure du logement 17 de forme triangulaire. Ces deux faces de la paroi intérieure s'étendent parallèlement à l'axe du balancier et définissent ensemble une gorge dont le fond est orienté en direction de l'axe du balancier. Dans l'exemple illustré, les deux faces en contact avec le piton 3 fond entre elles un angle de 60 degrés. On comprendra toutefois que l'invention ne se limite pas à cette valeur particulière de l'angle entre les faces du triangle. On notera en outre que, dans l'exemple illustré par les figures 1 et 2, la forme du piton 3 est essentiellement cylindrique. Un avantage lié à la symétrie de rotation inhérente à la forme cylindrique est que la position du piton relativement au porte-piton 5 peut être ajustée, non seulement longitudinalement, mais aussi en rotation. Cette possibilité supplémentaire peut s'avérer avantageuse lorsque le ressort spiral est réalisé en un matériau cassant. En effet, lorsque le ressort est réalisé avec un tel matériau, il n'est en principe pas possible de corriger une éventuelle déviation du ressort en déformant plastiquement son extrémité. Toutefois, dans les cas où la possibilité d'un réglage en rotation n'est pas nécessaire, on pourra avantageusement utiliser un piton 103 présentant un méplat (visible dans les figures 3 et 4) agencé pour coopérer avec la paroi intérieure du logement 13, de manière à caler angulairement le piton.Referring again to the figure 1 , we can see that the round form of the stud 3 does not allow him to come to lean against a top of the triangle (in other words, against the back of the throat). In the example shown, the pin is arranged to bear simultaneously against two faces of the inner wall of the housing 17 of triangular shape. These two faces of the inner wall extend parallel to the axis of the balance and together define a groove whose bottom is oriented towards the axis of the balance. In the illustrated example, the two faces in contact with the pin 3 merge between them at an angle of 60 degrees. It will be understood, however, that the invention is not limited to this particular value of the angle between the faces of the triangle. It should be noted that in the example illustrated by the figures 1 and 2 , the shape of the stud 3 is essentially cylindrical. One advantage of the rotational symmetry inherent in the cylindrical shape is that the position of the stud relative to the stud holder 5 can be adjusted, not only longitudinally, but also in rotation. This additional possibility may be advantageous when the spiral spring is made of a brittle material. Indeed, when the spring is made with such a material, it is in principle not possible to correct a possible deflection of the spring plastically deforming its end. However, in cases where the possibility of adjustment in rotation is not necessary, it is advantageous to use a pin 103 having a flat (visible in the figures 3 and 4) arranged to cooperate with the inner wall of the housing 13, so as to angularly wedge the piton.

Comme on l'a déjà mentionné, les figures 1 et 2 montrent encore un bras élastique 15 agencé pour appuyer latéralement sur le piton 3 de manière à l'immobiliser contre la paroi du logement 17. Conformément au mode de réalisation qui fait l'objet du présent exemple, le bras élastique 15 est pivoté sur la surface inférieure du porte-piton 5 par l'intermédiaire d'une partie annulaire 15a qui vient de matière avec le bras élastique 15 et qui est représentée en traits interrompus sur la figure 1. Précisons toutefois que selon une variante, le bras élastique 15 pourrait tout aussi bien être pivoté directement sur le coq 9 ou le coqueret 13. En se référant toujours aux figures 1 et 2, on peut voir que le bras élastique 15 est représenté dans une première position angulaire où il immobilise le piton 3 en appuyant latéralement directement sur le piton au niveau du rebord 19, là où le logement 17 se prolonge sous forme d'une rainure ouverte.As already mentioned, the figures 1 and 2 still show an elastic arm 15 arranged to press laterally on the stud 3 so as to immobilize it against the wall of the housing 17. In accordance with the embodiment which is the subject of the present example, the elastic arm 15 is pivoted on the surface lower of the peg carrier 5 via an annular portion 15a which comes from the material with the elastic arm 15 and which is shown in broken lines on the figure 1 . Note however that according to one variant, the elastic arm 15 could also be pivoted directly on the cock 9 or the cockpit 13. Referring always to figures 1 and 2 it can be seen that the elastic arm 15 is shown in a first angular position where it immobilizes the bolt 3 by pressing laterally directly on the stud at the rim 19, where the housing 17 is extended in the form of an open groove.

Comme on peut le voir sur la figure 1, dans l'exemple illustré, le bras élastique 15 est coudé de sorte que sa forme rappelle généralement celle d'un crochet. De plus, l'extrémité du bras élastique présente un profil de ressort-sautoir avec deux segments sensiblement droits qui définissent à leur jonction un sommet 15b. Le sommet 15b est situé à proximité de l'extrémité en forme de pointe 15c du bras élastique. En position de repos (lorsque le bras élastique n'est pas contraint), la distance séparant la pointe 15c de l'axe du balancier est normalement supérieure à la distance séparant l'axe du piton 3 de ce même axe de balancier. En revanche, la distance séparant le sommet 15b de l'axe du balancier est de préférence inférieure à la distance entre l'axe du piton et l'axe du balancier.As can be seen on the figure 1 , in the example shown, the elastic arm 15 is bent so that its shape generally reminds that of a hook. In addition, the end of the elastic arm has a spring-jumping profile with two substantially straight segments which define at their junction a vertex 15b. The top 15b is located near the tip-shaped end 15c of the elastic arm. In the rest position (when the elastic arm is not constrained), the distance separating the tip 15c from the axis of the balance is normally greater than the distance separating the axis of the peak 3 from this same balance shaft. On the other hand, the distance separating the vertex 15b from the axis of the balance is preferably less than the distance between the axis of the peak and the axis of the balance.

En se référant à la figure 1, on peut voir que le bras 15 est représenté dans une première position où il passe sous l'oreille du porte-piton 5 de manière à contourner le piton 3 de sorte qu'une partie distale du bras comprenant l'extrémité 15c ainsi que le sommet 15b se trouve de l'autre côté du piton. On comprendra que lorsque le bras élastique se trouve dans cette première position, il appuie sur le côté extérieur du piton 3 de sorte que ce dernier est rappelé en direction de l'axe du balancier. De plus, on comprendra également que la force de réaction du piton sur le bras élastique possède une composante tangentielle qui a pour effet de maintenir le bras élastique dans la position représentée dans la figure 1.Referring to the figure 1 it can be seen that the arm 15 is shown in a first position where it passes under the ear of the stud holder 5 so as to bypass the stud 3 so that a distal portion of the arm comprising the end 15c as well as the Summit 15b is on the other side of the peak. It will be understood that when the elastic arm is in this first position, it presses the outer side of the pin 3 so that the latter is biased towards the axis of the balance. In addition, it will also be understood that the reaction force of the stud on the elastic arm has a tangential component which has the effect of keeping the elastic arm in the position shown in FIG. figure 1 .

Selon l'invention, le bras élastique 15 est prévu pour pouvoir être pivoté par rapport au porte-piton 5. Si un horloger force le bras élastique à pivoter relativement au porte-piton dans le sens antihoraire, l'extrémité du bras glisse sur le piton 3 tout en étant repoussée en direction de l'extérieur. A l'instant où le sommet 15b franchit le piton en glissant, la composante tangentielle de la force de réaction exercée par le piton sur le bras élastique change de sens et fait pivoter rapidement le bras élastique 15 jusqu'à ce qu'il soit complètement désengagé du piton 3. On peut donc libérer le piton très facilement en faisant simplement passer le bras élastique 15 de la première position angulaire illustrée sur la figure 1 à une deuxième position angulaire désengagée du piton, par une simple rotation du bras élastique dans le sens antihoraire.According to the invention, the resilient arm 15 is provided to be pivotable relative to the stud holder 5. If a watchmaker forces the elastic arm to pivot relative to the stud holder counterclockwise, the end of the arm slides on the piton 3 while being pushed towards the outside. At the moment when the vertex 15b crosses the bolt by sliding, the tangential component of the reaction force exerted by the bolt on the elastic arm changes direction and rapidly rotates the elastic arm 15 until it is completely disengaged from the pin 3. It is therefore possible to release the pin very easily by simply passing the elastic arm 15 of the first angular position illustrated on the figure 1 at a second angular position disengaged from the peak, by a simple rotation of the resilient arm counterclockwise.

A l'inverse, il est possible de faire passer le bras élastique 15 de la deuxième position angulaire à la première en le faisant tourner dans le sens horaire. Comme la distance séparant la pointe 15c de l'axe du balancier est supérieure à la distance séparant l'axe du piton 3 de ce même axe de balancier, lorsque la point 15c rencontre le piton 3, elle glisse sur sa surface en s'écartant progressivement en direction de l'extérieur. A l'instant où le sommet 15b franchit le piton en glissant, la composante tangentielle de la force exercée par le bras élastique sur le piton change de direction et fait pivoter rapidement le bras élastique 15 jusqu'à la première position angulaire. Le piton étant alors immobilisé contre la paroi intérieure de son logement.Conversely, it is possible to move the elastic arm 15 from the second angular position to the first by rotating it clockwise. As the distance separating the tip 15c from the axis of the balance is greater than the distance separating the axis of the peak 3 from the same axis of balance, when the point 15c meets the peak 3, it slides on its surface by moving away gradually towards the outside. At the instant when the vertex 15b crosses the bolt by sliding, the tangential component of the force exerted by the elastic arm on the bolt changes direction and quickly rotates the elastic arm 15 to the first angular position. The pin is then immobilized against the inner wall of its housing.

Les figures 3 et 4 montrent deux variantes du mode de réalisation qui fait l'objet de la description détaillée. La variante représentée dans la figure 3A est pratiquement identique à celle représentée dans les figures 1 et 2. Les éléments représentés dans la figure 3A qui sont identiques à ceux des figures 1 et 2 sont désignés par les mêmes numéros de référence. En comparant les figures 1 et 3A, on peut observer que, contrairement au piton 3 qui était cylindrique, le piton 103 visible dans la figure 3A présente un méplat. Comme on l'a déjà mentionné, l'avantage d'avoir recours à un piton présentant un méplat est de permettre de caler angulairement le piton contre une des parois intérieures du logement 17.The figures 3 and 4 show two variants of the embodiment which is the subject of the detailed description. The variant represented in the figure 3A is virtually identical to that shown in figures 1 and 2 . The elements represented in the figure 3A which are identical to those of figures 1 and 2 are designated by the same reference numbers. Comparing the figures 1 and 3A , it can be observed that, contrary to the piton 3 which was cylindrical, the peak 103 visible in the figure 3A has a flat surface. As already mentioned, the advantage of using a stud with a flat is to allow angularly wedge the piton against one of the inner walls of the housing 17.

La figure 3B est vue partielle semblable à la figure 3A, mais montrant un bras élastiques 115 correspondant à une deuxième variante. Selon cette variante, le flanc intérieur du bras élastique 115 présente encore au voisinage du sommet 115b un siège en forme de V constitué à la jonction de deux segments sensiblement droits. Comme on le comprendra en se référant à la figure 3B, le siège en forme de V permet de mieux caler le piton 115. On comprendra en outre que diverses modifications et/ou améliorations évidentes pour un homme du métier peuvent être apportées au mode de réalisation qui fait l'objet de la présente description sans sortir du cadre de la présente invention définie par les revendications annexées. En particulier, le logement aménagé dans le porte-piton n'a pas besoin d'être triangulaire. Il peut avoir une forme quelconque. En particulier il peut être constitué par une rainure ouverte sur toute sa longueur.The figure 3B is partial view similar to the figure 3A but showing an elastic arm 115 corresponding to a second variant. According to this variant, the inner side of the elastic arm 115 still has in the vicinity of the top 115b a V-shaped seat formed at the junction two substantially straight segments. As will be understood by referring to the figure 3B , the V-shaped seat makes it possible to better wedge the piton 115. It will be further understood that various modifications and / or improvements obvious to a person skilled in the art can be made to the embodiment which is the subject of the present description without departing within the scope of the present invention defined by the appended claims. In particular, the housing arranged in the bolt carrier does not need to be triangular. It can have any form. In particular it can be constituted by an open groove along its entire length.
