- the invention relates to the field of watchmaking, and more particularly to the field of mechanical watchmaking, where the regulation of the driving energy is provided by a spring oscillator. More specifically, the invention relates to a pin holder for mechanical movement.
- a balance-spring system which includes a flywheel called a balance, associated with a spring in the form of a ribbon wound in a spiral, called a spiral.
- the hairspring is fixed on an axis integral in rotation with the balance; by an external end, the hairspring is fixed on a stud mounted on a stud holder itself integral with a fixed bridge (or cock).
- the hairspring is made from a steel alloy based on cobalt, nickel and chromium. Quenching and tempering are commonly applied to this alloy, which has the advantage of giving it a high elastic limit and therefore good breaking strength.
- Another advantage of steel is its repairability. But one drawback of steel is its magnetisability, which affects its behavior under load. (and therefore to the precision of the watch movement); in addition, fixing the eyebolt by gluing is delicate on steel.
- silicon has the advantage of having a low moment of inertia, a low coefficient of expansion, good resistance to corrosion and of being non-magnetic.
- the main drawback of silicon is its brittle nature, under the conditions described below.
- the rotation of the balance is maintained - and its oscillations counted - by an escape mechanism comprising an anchor driven by a low-amplitude oscillating movement, provided with two paddles which attack the teeth of an escape wheel.
- the escape wheel is imposed a step-by-step rotational movement, the frequency of which is determined by the frequency of oscillation of the anchor, itself fixed to the frequency of oscillation of the balance (c 'i.e. hairspring).

- the hairspring 21 rotates the axis 17 main, which it is integral with its internal end 22, with the balance 25 which is itself integral with the axis 17. Having reached a complete relaxation, the hairspring 21 comes to a stop (with the axis 17 and the balance 25 ) then, under the effect of its elasticity, tends to compress again and then drives the axis 17 and the balance 25 in a rotation in the opposite direction.
- the oscillations of the spiral system 21 - balance 17 serve to regulate the reciprocating tilting movements of the escape anchor, which is provided with a pair of paddles alternately attacking an escape wheel whose rotation step by step, at a frequency determined by the oscillations of the anchor (that is to say of the spring), is transmitted to a timer provided with one (or more) hand (s) indicating the hours (and / or minutes) .

- the central ring 47 of the upper element 45 comprises a projecting bush 51 driven into the ring 48 of the lower element, which secures the upper element 45 and the lower element 46.
- the central ring 47 of the upper element 45 is provided with a chamfer 52 complementary to a conical bearing surface 53 formed on the shock absorber 18, which ensures the rotational guidance of the racket 39 around the axis 17.
- the stops 42 jointly form for the hairspring 21 a counting point, which together with the internal end 22 defines an active (curvilinear) length on which depends the frequency of the oscillations of the hairspring 21.
- the (manual) rotation of the eccentric 44 varies. the angular position of the racket 39 and therefore of the counting point, which increases (or, conversely, decreases) the active length (and therefore the frequency of oscillations) of the hairspring 21.
- the finger (s) is (are) housed in a recessed reserve 54 formed in the deck 15 of the bridge 8.
- a graduation 55, as well as the signs "-" and "+”, engraved in the apron 15, provide the watchmaker with indications on the scale and the direction of rotation, useful to allow him to adjust finely (with a magnifying glass or a microscope, or even by means of a specific device, such as the REGO model marketed by the CENTAGORA company) the position of the eccentric 44 (notched for this purpose) - and therefore of the racket 39.
- the piton holder 29 is provided with a retaining stop for the piton 35 extracted from the 'notch 33.
- the rear tab 32 of the eyebolt 29 comprises an extension 56 which defines, beyond the notch 33, an elbow 57 forming this stop.
- the extension 56 comprises a radial portion 59 (substantially collinear with the inner section 58), and a transverse portion 60 which extends the radial portion 59 at right angles.
- the elbow 57 is defined at the junction between the radial portion 59 and the transverse portion 60.
- the transverse portion 60 of the extension 56 is advantageously spaced from the front tab 31 to form with it a passage 61 wide enough to allow the introduction (or forced withdrawal) of the pin 35, transversely.
- the rear tab 32 preferably has a fillet 62 for internal connection at the elbow 57.
- the peg 35 snapped into the notch 33 is illustrated in dotted lines on the FIG. 7 and on the FIG. 10 .
- the body 36 of the pin 35 cooperates with the facets of the notch 33 which thus ensures its retention for the needs of the ordinary operation of the hairspring 21 (and therefore of the movement 5).
- the pin 35 is extracted (that is to say clicked) from the notch 33 manually, by a radial movement outwards (that is to say tending to move the pin 35 away from the ring 30) , in the direction indicated by the arrows on the FIG. 7 and FIG. 10 .
- the equilibrium position of the hairspring 21 is reached when the eyebolt 35 is in the notch 33 of the eyebolt holder.
- the eyebolt therefore tends to return there, and thus to wedge itself in the elbow 57 (and more precisely in the leave 62) where it is thus retained, as illustrated in solid lines on the FIG. 8 and FIG. 10 .
- the elbow 57 (and therefore the stop that it forms) makes it possible to unclip the eyelet 35 without the risk of the latter escaping when it is extracted from the notch 31.
- the eyebolt 35 is then retained by the stop formed by the elbow 57, it is then possible to change the tool to ensure a more comfortable (and firmer) grip on the eyebolt 35 (eg by means of a pair of tweezers) with a view, for example, to completely dismantle the hairspring 21, by a vertical movement, as illustrated by the arrow on the FIG. 10 .
- the spitefulness is carried out in two stages.

Description
L'invention a trait au domaine de l'horlogerie, et plus particulièrement au domaine de l'horlogerie mécanique, où la régulation de l'énergie motrice est fournie par un oscillateur à ressort. L'invention concerne, plus précisément, un porte-piton pour un mouvement mécanique.The invention relates to the field of watchmaking, and more particularly to the field of mechanical watchmaking, where the regulation of the driving energy is provided by a spring oscillator. More specifically, the invention relates to a pin holder for mechanical movement.
Dans la plupart des montres mécaniques, l'énergie nécessaire à la rotation des aiguilles (par ex. des aiguilles indicatrices des minutes et des heures) est accumulée puis dispensée par un système balancier-spiral, qui comprend un volant d'inertie appelé balancier, associé à un ressort sous forme d'un ruban enroulé en spirale, appelé spiral.In most mechanical watches, the energy necessary for the rotation of the hands (e.g. minute and hour indicator hands) is accumulated and then dispensed by a balance-spring system, which includes a flywheel called a balance, associated with a spring in the form of a ribbon wound in a spiral, called a spiral.
Par une extrémité interne, le spiral est fixé sur un axe solidaire en rotation du balancier ; par une extrémité externe, le spiral est fixé sur un piton monté sur un porte-piton lui-même solidaire d'un pont (ou coq) fixe.By an internal end, the hairspring is fixed on an axis integral in rotation with the balance; by an external end, the hairspring is fixed on a stud mounted on a stud holder itself integral with a fixed bridge (or cock).
Traditionnellement, le spiral est fait dans un alliage d'acier à base de cobalt, nickel et chrome. Une trempe et un revenu sont couramment appliqués à cet alliage, ce qui a pour avantage de lui conférer une haute limite élastique et donc une bonne résistance à la rupture. Un autre avantage de l'acier est son aptitude à la réparation. Mais un inconvénient de l'acier est son caractère magnétisable, qui nuit à son comportement en charge (et donc à la précision du mouvement horloger) ; en outre, la fixation du piton par collage est délicate sur l'acier.Traditionally, the hairspring is made from a steel alloy based on cobalt, nickel and chromium. Quenching and tempering are commonly applied to this alloy, which has the advantage of giving it a high elastic limit and therefore good breaking strength. Another advantage of steel is its repairability. But one drawback of steel is its magnetisability, which affects its behavior under load. (and therefore to the precision of the watch movement); in addition, fixing the eyebolt by gluing is delicate on steel.
Il est également connu (quoique moins fréquent) de recourir, pour la fabrication du spiral, au silicium.
La rotation du balancier est entretenue - et ses oscillations comptées - par un mécanisme d'échappement comprenant une ancre animée d'un mouvement oscillant de faible amplitude, pourvue de deux palettes qui attaquent les dents d'une roue d'échappement. Ainsi attaquée, la roue d'échappement se voit imposer un mouvement de rotation pas-à-pas dont la fréquence est déterminée par la fréquence d'oscillation de l'ancre, elle-même calée sur la fréquence d'oscillation du balancier (c'est-à-dire du spiral).The rotation of the balance is maintained - and its oscillations counted - by an escape mechanism comprising an anchor driven by a low-amplitude oscillating movement, provided with two paddles which attack the teeth of an escape wheel. Thus attacked, the escape wheel is imposed a step-by-step rotational movement, the frequency of which is determined by the frequency of oscillation of the anchor, itself fixed to the frequency of oscillation of the balance (c 'i.e. hairspring).
Dans un mécanisme d'échappement traditionnel, la fréquence d'oscillation est d'environ 4 Hz, soit environ 28 800 alternances par heure (Ah). Un objectif des bons horlogers est d'assurer l'isochronisme et la régularité des oscillations (ou constance de la marche) du balancier.In a traditional escapement mechanism, the oscillation frequency is about 4 Hz, or about 28,800 vibrations per hour (Ah). One objective of good watchmakers is to ensure the isochronism and regularity of the oscillations (or constancy of the rate) of the balance.
Il est connu de régler la marche du balancier en ajustant la longueur active du spiral, définie comme la longueur curviligne entre son extrémité interne et un point de comptage, localisé au voisinage de l'extrémité externe du spiral et généralement défini par une paire de butées portées par une clé montée sur une raquette.It is known to regulate the rate of the balance by adjusting the active length of the hairspring, defined as the curvilinear length between its inner end and a counting point, located near the outer end of the hairspring and generally defined by a pair of stops carried by a key mounted on a racket.
En fonctionnement, cette raquette est fixe en rotation par rapport à l'axe du spiral. Cependant, il est possible, par une intervention manuelle, d'en régler finement la position angulaire, par ex. par pivotement, au moyen d'un tournevis, d'un excentrique agissant sur la raquette à la manière d'une came.In operation, this racket is fixed in rotation with respect to the axis of the hairspring. However, it is possible, by manual intervention, to finely adjust its angular position, e.g. by pivoting, by means of a screwdriver, of an eccentric acting on the racket in the manner of a cam.
L'ensemble comprenant le pont, la raquette, la clé, le porte-piton, le piton, l'axe, le ressort et le balancier, est couramment dénommé « organe réglant ». Des exemples d'organes réglants sont proposés par la demande internationale
Par ailleurs, un porte-piton est connu du document
Certaines interventions sur l'organe réglant peuvent nécessiter le déroulage (voire même le démontage complet) du spiral. Il convient alors de dissocier le piton, solidaire de l'extrémité externe du spiral, du porte-piton.Certain interventions on the regulating organ may require unwinding (or even complete disassembly) of the hairspring. It is then necessary to separate the eyebolt, integral with the outer end of the balance spring, from the eyebolt holder.
Cette opération, appelée dépitonnage, est délicate. L'horloger saisit généralement le piton au moyen d'une paire de brucelles, puis le retire délicatement du porte-piton.This operation, called spitefulness, is delicate. The watchmaker usually grasps the eyebolt with a pair of tweezers, then gently removes it from the eyebolt holder.
Cependant, il arrive fréquemment que le piton échappe aux brucelles, ce qui provoque une brusque détente du spiral dont l'extrémité externe se trouve ainsi libérée.However, it frequently happens that the eyebolt escapes the tweezers, which causes a sudden relaxation of the hairspring, the outer end of which is thus released.
Cet incident est sans conséquence lorsque le spiral est en acier (et plus précisément en acier allié, comme indiqué ci-dessus), car les traitements de trempe et de revenu qui lui sont appliqués le rendent suffisamment ductile pour permettre un ré-enroulage du spiral.This incident is of no consequence when the hairspring is made of steel (and more precisely of alloy steel, as indicated above), because the quenching and tempering treatments which are given to it applied make it sufficiently ductile to allow rewinding of the hairspring.
En revanche, ce même incident est dramatique pour un spiral en silicium qui, statistiquement, casse dans plus d'un cas sur deux.On the other hand, this same incident is dramatic for a silicon balance spring which, statistically, breaks in more than one in two cases.
L'invention a pour objectif est de permettre un dépitonnage en limitant, voire en supprimant, le risque de casse.The object of the invention is to allow spitefulness by limiting, or even eliminating, the risk of breakage.
Il est proposé, en premier lieu, un porte-piton tel que défini dans la revendication 1.Firstly, there is proposed an eyebolt as defined in claim 1.
De la sorte, le piton extrait de l'encoche vient se caler dans la butée, ce qui empêche le ressort (spiral) de se détendre brusquement lors du dépitonnage. Le risque de casse du ressort est ainsi limité.In this way, the eyebolt extracted from the notch comes to be wedged in the stopper, which prevents the spring (hairspring) from suddenly slackening during spite. The risk of the spring breaking is thus limited.
Des caractéristiques avantageuses du porte-piton, pouvant être prises seules ou selon toutes les combinaisons techniquement possibles, sont définies dans les revendications dépendantes.Advantageous characteristics of the eyebolt, which can be taken alone or according to any technically possible combination, are defined in the dependent claims.
Il est proposé, en deuxième lieu, un ensemble comportant un tel porte-piton.Secondly, an assembly is proposed comprising such an eyebolt holder.
Des caractéristiques avantageuses de l'ensemble, pouvant être prises seules ou selon toutes les combinaisons techniquement possibles, sont définies dans les revendications dépendantes.Advantageous characteristics of the assembly, which can be taken alone or according to any technically possible combination, are defined in the dependent claims.
Il est proposé, en troisième lieu, un mouvement d'horlogerie comportant un tel ensemble.Thirdly, a timepiece movement comprising such an assembly is proposed.
Il est proposé en quatrième lieu, une montre comprenant un tel mouvement d'horlogerie mécanique.Fourthly, a watch is proposed comprising such a mechanical clockwork movement.

La montre 1 comprend également, pour le port au poignet, un bracelet 3 qui vient se fixer sur la carrure 2 entre des cornes 4 formées en saillie sur celle-ci.The watch 1 also comprises, for wearing on the wrist, a
La montre 1 comporte en outre une glace et un fond (non représentés), fixés sur la carrure 2 de part et d'autre de celle-ci.Watch 1 further comprises a crystal and a back (not shown), fixed to the
La montre 1 comporte, enfin, un mouvement 5 d'horlogerie, ci-après simplement dénommé « mouvement », qui comprend une platine 6 destinée à venir se loger dans la carrure 2 en étant fixé à celle-ci, par ex. au moyen de vis. La platine 6 forme un support pour divers mécanismes tels que rouage, organe réglant, échappement, transmission, minuterie, remontoir (liste non exhaustive).The watch 1 comprises, finally, a watch movement 5, hereinafter simply referred to as “movement”, which comprises a plate 6 intended to be housed in the
Ce mouvement 5 d'horlogerie est mécanique, sa source d'énergie motrice étant fournie par un ressort de barillet et régulée par un oscillateur à ressort. Pour abriter cet oscillateur, le mouvement 5 intègre un organe réglant 7, qui est monté sur la platine 6.This clockwork movement 5 is mechanical, its motive power source being provided by a barrel spring and regulated by a spring oscillator. To house this oscillator, movement 5 incorporates a regulating
L'organe réglant 7 comprend, en premier lieu, un pont 8. Ce pont 8, également dénommé « coq », se présente sous forme d'une pièce rigide (qui peut être métallique) fixée sur la platine 6. Le pont 8 forme à la fois support et guide pour les autres composants de l'organe réglant 7.The regulating
Selon un mode de réalisation illustré sur les dessins, et notamment sur la
Le positionnement précis du pont 8 par rapport à la platine 6 est assuré au moyen de pieds 13 qui font saillie d'une face interne de l'embase 9 et viennent s'emboîter dans des alésages 14 complémentaires pratiqués dans la platine 6.The precise positioning of the
Pour la fixation et le guidage des autres composants de l'organe réglant 7, le pont 8 comprend un tablier 15, formé d'un seul tenant avec l'embase 9. Le pont 8 est pourvu d'un alésage 16 pratiqué dans le tablier 15, à une extrémité en porte-à-faux de celui-ci.For fixing and guiding the other components of the regulating
L'organe réglant 7 comprend, en deuxième lieu, un axe 17 principal, qui se présente sous forme d'une pièce monobloc étagée montée en rotation par rapport au pont 8. Plus précisément, l'axe 17 principal est monté en rotation entre la platine 6 et le pont 8.The regulating
Selon un mode particulier de réalisation (illustré notamment sur les
Comme on le voit par ailleurs sur la
Pour limiter les frottements lors de la rotation de l'axe 17 principal, les extrémités de celui-ci coopèrent avantageusement avec un minéral dur, tel que rubis ou diamant.To limit friction during rotation of the
L'organe réglant 7 comprend, en troisième lieu, un ressort 21 enroulé en spirale autour de l'axe 17 principal. Plus précisément, le ressort 21, ci-après appelé « spiral » présente une extrémité 22 interne, solidaire de l'axe 17, et une spire 23 externe qui se termine par une extrémité 24 externe.The regulating
Selon un mode avantageux de réalisation, le spiral 21 est réalisé en silicium, éventuellement recouvert d'une couche d'oxyde.According to an advantageous embodiment, the
Lorsqu'il est armé, le spiral 21 fournit un couple de rappel qui s'exerce sur l'axe 17.When it is armed, the
Pour augmenter ce couple fourni par le spiral 21 et l'amplitude de ses oscillations, l'organe réglant 7 comprend, en quatrième lieu, un volant d'inertie sous forme d'un balancier 25 solidaire en rotation de l'axe 17.In order to increase this torque supplied by the
Ce balancier 25, réalisé par ex. en laiton, comprend un moyeu 26, par lequel il est chassé sur l'axe 17, une serge 27, et des rayons 28 (ici au nombre de trois, mais ce nombre n'est qu'illustratif) qui relient le moyeu 26 à la serge 27.This
L'organe réglant 7 comprend, en cinquième lieu, un porte-piton 29 qui comprend un anneau 30, par lequel il est solidaire du pont 8, et une paire de pattes, à savoir une patte 31 avant et une patte 32 arrière (avant et arrière étant définis dans le sens d'enroulement du spiral 21, depuis l'extrémité 22 interne vers l'extrémité 24 externe) qui font saillie radialement de l'anneau 30 et, ensemble, définissent une encoche 33.The regulating
Le porte-piton 29 est avantageusement réalisé dans un matériau métallique, par ex. en acier.The
Selon un mode de réalisation illustré sur la
L'organe réglant 7 comprend, en sixième lieu, un piton 35 solidaire de l'extrémité 24 externe du spiral 21. Ce piton 35 est par ex. réalisé en acier. Selon un mode de réalisation, le piton 35 est fixé à l'extrémité 24 externe du spiral 21 par collage, au moyen d'une colle photo-polymérisable dont les propriétés d'adhérence sont activées par exposition à un rayonnement photonique dans l'ultraviolet.The regulating
Comme illustré sur les dessins, et plus particulièrement sur les
- une tête 37 élargie par laquelle le piton 35 est en appui contre le porte-
piton 29, une fourche 38 dans laquelle est logée (en étant collée) l'extrémité 24 externe duspiral 21.
- an
enlarged head 37 by which theeyebolt 35 bears against theeyebolt 29, - a
fork 38 in which is housed (by being glued) theouter end 24 of thehairspring 21.
Ainsi fixé sur le porte-piton 29, le piton 35 assure l'assujettissement (c'est-à-dire l'immobilisation par rapport au pont 8) de l'extrémité 24 externe du spiral 21.Thus fixed on the
Les oscillations du spiral 21 sont entretenues (et comptées) par une ancre d'échappement (non représentée) qui lui communique une énergie cinétique, laquelle arme le spiral 21 en l'entraînant au-delà de sa position d'équilibre.The oscillations of the
En se désarmant, c'est-à-dire en tendant à retrouver sa position d'équilibre, le spiral 21 entraîne en rotation l'axe 17 principal, dont il est solidaire par son extrémité 22 interne, avec le balancier 25 qui est lui-même solidaire de l'axe 17. Parvenu à une détente complète, le spiral 21 s'immobilise (avec l'axe 17 et le balancier 25) puis, sous l'effet de son élasticité, tend à se comprimer à nouveau et entraîne alors l'axe 17 et le balancier 25 dans une rotation en sens inverse.By disarming, that is to say by tending to regain its position of equilibrium, the
Les oscillations du système spiral 21 - balancier 17 servent à réguler les mouvements de basculement alternatif de l'ancre d'échappement, laquelle est pourvue d'une paire de palettes attaquant alternativement une roue d'échappement dont la rotation pas-à-pas, à une fréquence déterminée par les oscillations de l'ancre (c'est-à-dire du ressort), est transmise à une minuterie pourvue d'une (ou plusieurs) aiguille(s) indicatrices des heures (et/ou des minutes).The oscillations of the spiral system 21 -
La fréquence des oscillations du système spiral 21 - balancier 17 peut être réglée finement, à la main, par une intervention sur l'organe réglant 7, qui comprend à cet effet, en septième lieu, une raquette 39.The frequency of the oscillations of the spiral system 21 -
La raquette 39 est fixée sur le pont 8 avec possibilité de débattement angulaire par rapport à celui-ci autour de l'axe 17 principal.The
Plus précisément, la raquette 39 comporte :
une queue 40 portant une clé 41 qui définit une paire de butées 42 disposées de part et d'autre de laspire 23 externe duspiral 21, et- au moins
un doigt 43 d'indexage qui coopère avecun excentrique 44, monté sur lepont 8 pour ajuster la position angulaire de la raquette 39 par rotation de l'excentrique 44.
- a
shank 40 carrying a key 41 which defines a pair ofstops 42 arranged on either side of theouter turn 23 of thehairspring 21, and - at least one
indexing finger 43 which cooperates with an eccentric 44, mounted on thebridge 8 to adjust the angular position of theracket 39 by rotation of the eccentric 44.
Selon un mode préféré de réalisation illustré notamment sur les
- Un élément 45 supérieur de raquette, qui porte le doigt 43 d'indexage ;
- Un élément 46 inférieur de raquette, qui porte la
queue 40.
- An
upper racket element 45, which carries theindexing finger 43; - A
lower racket element 46, which carries thetail 40.
Dans l'exemple illustré, l'élément 45 supérieur comprend une bague 47 centrale et une paire de doigts 43 d'indexage qui s'étendent radialement en V à partir de cette bague 47 centrale.In the example illustrated, the
Dans ce même exemple, l'élément 46 inférieur comprend un anneau 48 ; la queue 40 comporte une paire de languettes 49 qui font saillie radialement de l'anneau 48 et définissent entre elles une fente 50 dans laquelle est insérée la clé 41.In this same example, the
La bague 47 centrale de l'élément 45 supérieur comprend une douille 51 en saillie chassée dans l'anneau 48 de l'élément inférieur, ce qui solidarise l'élément 45 supérieur et l'élément 46 inférieur.The
Par ailleurs, la bague 47 centrale de l'élément 45 supérieur est pourvue d'un chanfrein 52 complémentaire d'une portée 53 conique formée sur l'amortisseur de chocs 18, qui assure le guidage en rotation de la raquette 39 autour de l'axe 17.Furthermore, the
Les butées 42 forment conjointement pour le spiral 21 un point de comptage, qui avec l'extrémité 22 interne définit une longueur (curviligne) active dont dépend la fréquence des oscillations du spiral 21. La rotation (manuelle) de l'excentrique 44 fait varier la position angulaire de la raquette 39 et donc du point de comptage, ce qui augmente (ou, a contrario, diminue) la longueur active (et donc la fréquence des oscillations) du spiral 21.The stops 42 jointly form for the hairspring 21 a counting point, which together with the
Selon un mode de réalisation illustré sur les
Lors des interventions manuelles sur l'organe réglant 7, le dépitonnage, c'est-à-dire le retrait du piton 35 du porte-piton 29, peut être nécessaire. Pour éviter que le piton libéré 35 du porte-piton 29 ne soit projeté au loin sous l'effet d'une brusque détente du spiral 21, le porte-piton 29 est pourvu d'une butée de retenue pour le piton 35 extrait de l'encoche 33.During manual interventions on the regulating
Plus précisément, la patte 32 arrière du porte-piton 29 comprend une prolongation 56 qui définit, au-delà de l'encoche 33, un coude 57 formant cette butée.More specifically, the
Ainsi, la patte 32 arrière comprend, d'un seul tenant :
Une section 58 intérieure, qui avec la patte 31 avant définit l'encoche 33,La prolongation 56, qui s'étend radialement dans la continuité de lasection 58 intérieure.
- An
interior section 58, which together with thefront tab 31 defines thenotch 33, - The
extension 56, which extends radially in continuity with theinterior section 58.
Selon un mode de réalisation illustré sur les dessins, et plus particulièrement sur les
Le coude 57 est défini à la jonction entre la portion 59 radiale et la portion 60 transversale.The
Comme on le voit bien sur la
La patte 32 arrière présente de préférence un congé 62 de raccordement intérieur au niveau du coude 57.The
Le piton 35 encliqueté dans l'encoche 33 est illustré en pointillés sur la
Le piton 35 est extrait (c'est-à-dire décliqueté) de l'encoche 33 manuellement, par un mouvement radial vers l'extérieur (c'est-à-dire tendant à éloigner le piton 35 de l'anneau 30), dans le sens indiqué par les flèches sur les
Le coude 57 (et donc la butée qu'il forme) permet de décliqueter le piton 35 sans risque de voir celui-ci s'échapper au moment où il est extrait de l'encoche 31.The elbow 57 (and therefore the stop that it forms) makes it possible to unclip the
Il est alors possible de modifier la prise du piton 7 pour en assurer un maintien plus ferme et le dégager alors complètement du porte-piton 29, par ex. en vue de démonter le spiral 21.It is then possible to modify the grip of the
Comme le piton 35 est alors retenu par la butée formée par le coude 57, il est possible de changer ensuite d'outil pour assurer une prise plus confortable (et plus ferme) du piton 35 (par ex. au moyen d'une paire de brucelles) en vue par exemple de démonter complètement le spiral 21, par un mouvement vertical, comme illustré par la flèche sur la
Il en résulte un risque diminué, voire supprimé, de casse du spiral 21 lors du dépitonnage, au bénéfice de la fiabilité de l'organe réglant 7.This results in a reduced risk, or even eliminated, of breakage of the
