Description

La présente invention est relative à un dispositif d'articulation entre deux maillons composant un bracelet non extensible, ledit dispositif comportant des première et seconde goupilles attachées, la première à un premier maillon, la seconde à un second maillon faisant face au premier, et des organes de liaison reliant lesdites première et seconde goupilles.The present invention relates to a device of articulation between two links making up a bracelet not extensible, said device comprising first and second pins attached, the first to a first link, the second to a second link facing the first, and connecting members connecting said first and second pins.

On connaít déjà un dispositif d'articulation répondant à la définition générique donnée ci-dessus. Le document CH-A-661 184 décrit des maillons constitués chacun d'une coquille supérieure et d'une coquille inférieure. Des trous borgnes reçoivent des barrettes à ressort au nombre de deux par maillon. L'articulation entre deux maillons se compose donc de deux barrettes reliées ensemble par des brides de liaison qui sont des pièces de tôle découpées et pliées. Ce dispositif présente l'inconvénient de ne pas cacher au regard l'endroit de l'articulation et d'être fragile par l'utilisation d'une tôle qui peut se casser par fatigue.We already know an articulation device meeting the generic definition given above. The document CH-A-661 184 describes constituted links each of a top shell and a shell lower. Blind holes receive bars to comes out two in number per link. The articulation between two links therefore consists of two bars connected together by connecting flanges which are cut and folded sheet metal parts. This device presents the disadvantage of not hiding the place of the joint and to be fragile by the use of a sheet metal which can break by fatigue.

Pour éviter ces inconvénients et pour proposer un système d'articulation de haute qualité technique, le dispositif d'articulation selon l'invention est caractérisé en ce qu'il est entièrement recouvert par une coiffe entourant les maillons, la coiffe couvrant en outre au moins les bords desdits maillons quel que soit l'angle de rotation de ceux-ci, cette coiffe étant maintenue en place par un insert la traversant et venant se cranter entre les première et seconde goupilles.To avoid these drawbacks and to propose a high-quality articulation system, the articulation device according to the invention is characterized in that it is completely covered by a cap surrounding the links, the cap further covering at least the edges of said links whatever the angle of rotation of these, this cap being maintained in placed by an insert crossing it and coming to grip between the first and second pins.

L'invention va être décrite ci-après, à titre d'exemple et en se référant au dessin qui l'illustre dans lequel :

  • la figure 1 est une vue de dessus du dispositif d'articulation selon l'invention, vue dans laquelle la partie supérieure de la coiffe a été coupée,
  • la figure 2 est une vue de dessus montrant séparément tous les éléments utilisés pour former l'articulation de la figure 1, à l'exception de l'insert,
  • les figures 3 et 4 sont des vues de dessus respectivement d'un premier et d'un second mode d'exécution de l'insert propre à maintenir la coiffe en place,
  • la figure 5 est une vue de côté du dispositif d'articulation selon l'invention, coupé selon la ligne V-V de la figure 1,
  • la figure 6 est une vue de côté montrant séparément les éléments utilisés pour former l'articulation de la figure 5, à l'exception de l'insert,
  • les figures 7 et 8 sont des vues de côté respectivement d'un premier et d'un second mode d'exécution de l'insert,
  • la figure 9 est une vue de face du dispositif d'articulation selon l'invention, coupé selon la ligne IX-IX de la figure 1,
  • la figure 10 est une vue de face montrant séparément les éléments utilisés pour former l'articulation de la figure 9, à l'exception de l'insert,
  • les figures 11 et 12 sont des vues de face respectivement d'un premier et d'un second mode d'exécution de l'insert,
  • la figure 13 est une vue de dessus d'une portion de bracelet assemblé, et
  • la figure 14 est une vue de dessous d'une portion de bracelet assemblé.
The invention will be described below, by way of example and with reference to the drawing which illustrates it in which:
  • FIG. 1 is a top view of the articulation device according to the invention, a view in which the upper part of the cap has been cut,
  • FIG. 2 is a top view showing separately all the elements used to form the joint of FIG. 1, with the exception of the insert,
  • FIGS. 3 and 4 are top views respectively of a first and of a second embodiment of the insert suitable for holding the cap in place,

  • FIG. 6 is a side view showing separately the elements used to form the joint of FIG. 5, with the exception of the insert,
  • FIGS. 7 and 8 are side views respectively of a first and of a second embodiment of the insert,
  • FIG. 9 is a front view of the articulation device according to the invention, cut along the line IX-IX of FIG. 1,
  • FIG. 10 is a front view showing separately the elements used to form the joint of FIG. 9, with the exception of the insert,

  • FIG. 13 is a top view of a portion of assembled bracelet, and
  • Figure 14 is a bottom view of a portion of assembled bracelet.

Si l'on se réfère maintenant à la figure 1, on voit le dispositif d'articulation selon l'invention qui comprend essentiellement un premier maillon 2 auquel est attachée une première goupille 4 et un second maillon 2' auquel est attachée une seconde goupille 4'. Le premier maillon 2 avec sa goupille 4 fait face au second maillon 2' avec sa goupille 4'. Les goupilles 4 et 4' sont reliées ensemble au moyen d'organes de liaison 3 et 3'. La figure 1 montre encore que le dispositif d'articulation est entièrement recouvert par une coiffe 1, coupée dans cette figure de sorte que ne sont visibles que les parties latérales de ladite coiffe. La coiffe 1 entoure complètement les maillons 2 et 2' et au moins les bords 10 et 10' de ceux-ci, ce qui apparaít mieux sur les coupes des figures 1 et 5. La figure 5 fait apparaítre plus particulièrement que les bords 10 et 10' des maillons 2 et 2' sont recouverts par la coiffe 1 quel que soit l'angle de rotation des maillons 2 et 2'. Enfin les figures 1, 5 et 9 montrent que la coiffe 1 est maintenue en place par un insert 5 qui traverse la coiffe par une ouverture 19 et vient se cranter entre les première et seconde goupilles 4 et 4'.If we now refer to Figure 1, we see the articulation device according to the invention which essentially comprises a first link 2 to which is attached a first pin 4 and a second link 2 ' to which is attached a second pin 4 '. The first link 2 with its pin 4 faces the second link 2 'with its pin 4'. Pins 4 and 4 'are connected together by means of connecting members 3 and 3 '. The figure 1 also shows that the articulation device is completely covered by a cap 1, cut in this figure so that only the parts are visible lateral of said cap. Cap 1 surrounds links 2 and 2 'completely and at least the edges 10 and 10 'of these, which appears better on the cuts Figures 1 and 5. Figure 5 shows more particularly that the edges 10 and 10 ′ of the links 2 and 2 'are covered by the cover 1 whatever the angle of rotation of links 2 and 2 '. Finally Figures 1, 5 and 9 show that the cap 1 is held in place by an insert 5 which passes through the cap through an opening 19 and just locks between the first and second pins 4 and 4 '.

Le dispositif d'articulation qui vient d'être décrit dans sa généralité va se répéter de manière semblable pour toutes les autres articulations du bracelet pour donner l'aspect fini du bracelet montré aux figures 13 et 14. La figure 13 est une vue de dessus d'une portion de ce bracelet, celle qui est apparente au regard. On voit une succession régulière de coiffes 1 et de maillons 2 et 2', les coiffes surmontant les maillons et conférant au bracelet une esthétique nouvelle d'un bel aspect. Coiffes et maillons peuvent être réalisés en matériaux les plus divers, par exemple de l'acier inoxydable ou de l'or. On pourrait alterner ces matériaux, par exemple en utilisant de l'acier pour les maillons 2 et de l'or pour les coiffes 1 et obtenir ainsi un bracelet bicolore du plus bel effet. Des matières synthétiques pourraient aussi être mises à profit, des composites contenant des fibres de carbone par exemple. La figure 14 est une vue de dessous du bracelet assemblé, celle qui se trouve contre le poignet du porteur. On voit dans cette figure, en plus des maillons 2 et des coiffes 1 déjà cités, les inserts 5 ou 6 servant à bloquer les coiffes 1, ces inserts étant naturellement cachés au regard.The articulation device which has just been described in general will repeat itself in a similar way for all the other joints of the bracelet to give the finished appearance of the bracelet shown in Figures 13 and 14. The Figure 13 is a top view of a portion of this bracelet, the one that is apparent to the eye. We see a regular succession of caps 1 and links 2 and 2 ', the caps over the links and giving the bracelet a new aesthetic of a beautiful aspect. Headdresses and links can be made of the most various, for example stainless steel or gold. We could alternate these materials, for example using steel for the links 2 and gold for the caps 1 and thus obtain a two-tone bracelet with the most beautiful effect. Synthetic materials could also be used profit, composites containing carbon fibers by example. Figure 14 is a bottom view of the bracelet assembled, the one that is against the wrist of the carrier. We see in this figure, in addition to the links 2 and caps 1 already mentioned, the inserts 5 or 6 serving to block the caps 1, these inserts being naturally hidden from view.

On va maintenant décrire plus en détail un mode de réalisation préféré du dispositif d'articulation selon l'invention. On se servira pour cela, non seulement des figures 1, 5 et 9 déjà citées, mais encore des figures 2, 6 et 10 qui présentent respectivement, des vues de dessus, de côté et de face des éléments utilisés pour former le dispositif d'articulation.We will now describe in more detail a mode of preferred embodiment of the articulation device according to the invention. We will use for this, not only the Figures 1, 5 and 9 already cited, but also Figures 2, 6 and 10 which respectively show top views, side and front of the elements used to form the articulation device.

Comme cela est bien apparent aux figures 1 et 2, le premier maillon 2 est pourvu de première et seconde oreilles 11 et 11' disposées sensiblement aux extrémités dudit maillon 2. Ces oreilles 11 et 11' sont percées respectivement de trous 12 et 12' traversés par la première goupille 4. De façon analogue, le second maillon 2' est pourvu de première et seconde oreilles 13 et 13' disposées sensiblement aux extrémités dudit maillon 2'. Les oreilles 13 et 13' sont percées respectivement de trous 14 et 14' traversés par la seconde goupille 4'. Des organes de liaison relient entre elles les goupilles. Ces organes consistent en des premier et second manchons 3 et 3' percés chacun d'un premier trou 15 et 15' qui sont traversés par la première goupille 4 et d'un second trou 16 et 16' qui sont traversés par la seconde goupille 4'. Ces manchons 3 et 3' sont situés entre les premières et secondes oreilles référencées respectivement 11, 13 et 11', 13' et prennent appui contre elles. Dans l'espace laissé libre entre les manchons 3 et 3' vient se loger l'insert dont il a déjà été question, cet insert venant se cranter entre les premier et second manchons 3 et 3' pour fixer la coiffe 1 sur le dispositif d'articulation, comme cela va être exposé ci-dessous.As is apparent from Figures 1 and 2, the first link 2 is provided with first and second ears 11 and 11 'arranged substantially at the ends of said link 2. These ears 11 and 11 ′ are pierced holes 12 and 12 'respectively crossed by the first pin 4. Similarly, the second link 2 'has first and second ears 13 and 13' arranged substantially at the ends of said link 2 '. The ears 13 and 13 'are pierced respectively with holes 14 and 14 'crossed by the second pin 4'. Of connecting members interconnect the pins. These organs consist of first and second sleeves 3 and 3 'each drilled with a first hole 15 and 15' which are crossed by the first pin 4 and a second hole 16 and 16 'which are crossed by the second pin 4'. These sleeves 3 and 3 'are located between the first and second ears referenced respectively 11, 13 and 11 ', 13' and lean against them. In the space left free between the sleeves 3 and 3 'is housed the insert which has already been discussed, this insert coming notching between the first and second sleeves 3 and 3 'to fix the cover 1 on the articulation device, as this will be discussed below.

Il est prévu de proposer cet insert selon deux modes d'exécution, un premier mode dit indémontable et un second mode dit démontable. Dans les deux cas l'insert présente une forme oblongue et traverse un trou 19 pratiqué sous la coiffe 1. Ce trou 19 présente la même forme oblongue que l'insert, ce dernier étant équipé d'une collerette 20 d'arrêt s'appuyant sous la coiffe 1 (voir par exemple les figures 11 et 12). Ces deux modes d'exécution vont être décrits maintenant dans le détail.It is planned to offer this insert in two modes of execution, a first mode known as non-removable and a second so-called removable mode. In both cases the insert is present an oblong shape and passes through a hole 19 made under the cap 1. This hole 19 has the same oblong shape as the insert, the latter being fitted with a collar 20 stop under the cover 1 (see for example the Figures 11 and 12). These two modes of execution will be now described in detail.

L'insert indémontable est illustré aux figures 1, 3, 5, 7, 9, 11 et 14. Il porte la référence 5 et est fait d'une seule pièce. Comme mentionné ci-dessus, l'insert 5 présente une forme oblongue dont la direction allongée X (voir figures 9 et 11) occupe l'espace laissé libre entre les premier et second manchons 3 et 3'. Comme le montre bien les figures 5 et 7, la partie supérieure 21 de l'insert 5 est élastique, cette élasticité lui étant conférée par une saignée 30 pratiquée dans ladite partie supérieure 21. Comme le montrent bien les figures 5 et 7, cette partie supérieure 21 est munie de première et seconde alvéoles allongées 22 et 23 qui se tournent le dos. Comme on peut le voir en figure 5, ces alvéoles 22 et 23 sont arrangées et dimensionnées pour venir se cranter respectivement dans les première et seconde goupilles 4 et 4' quand l'insert 5 est introduit à fond sous la coiffe 1. Ce système est indémontable en ce sens qu'il est très difficile d'extraire l'insert 5 sans le détériorer, même si cet insert est réalisé en matière plastique. On réservera donc ce mode d'exécution pour la partie du bracelet qui n'a pas besoin d'être raccourcie ou allongée.The non-removable insert is illustrated in Figures 1, 3, 5, 7, 9, 11 and 14. It bears the reference 5 and is made in one piece. As mentioned above, insert 5 has an oblong shape whose elongated direction X (see figures 9 and 11) occupies the space left free between the first and second sleeves 3 and 3 '. As shown in Figures 5 and 7, the upper part 21 of insert 5 is elastic, this elasticity being conferred by a groove 30 made in said part upper 21. As shown in Figures 5 and 7, this upper part 21 is provided with first and second elongated cells 22 and 23 which turn on back. As can be seen in FIG. 5, these cells 22 and 23 are arranged and sized to fit respectively in the first and second pins 4 and 4 'when the insert 5 is fully inserted under the cover 1. This system cannot be dismantled in the sense that it is very difficult to extract insert 5 without damaging it, even if this insert is made of plastic. We will therefore reserve this mode of execution for the part of the bracelet that does not need to be shortened or lengthened.

L'insert démontable est illustré aux figures 4, 8, 12 et 14 et peut remplacer l'insert indémontable illustré aux figures 1, 5 et 9. Comme le montrent les figures 4, 8 et 12, cet insert est réalisé en deux parties : un capot 6 de forme oblongue s'ajustant dans le trou 19 de la coiffe 1 avec sa collerette d'appui 20 et deux vis 7 et 7' traversant ce capot 6 dans le sens des flèches B. Comme on le voit bien sur les figures 4, 8 et 12, les vis 7 et 7' présentent une tête cylindrique 31 et 31' susceptible de s'ajuster dans l'alésage 32 du capot 6, la tête étant munie d'une collerette d'arrêt 33 et d'une fente 34 susceptible de recevoir un tournevis. La partie supérieure 24 de chaque vis 7 et 7' présente la forme d'un parallélépipède rectangle qui est pourvu de première et seconde alvéoles 25 et 26 comme cela est bien montré sur les figures 8 et 12. Ces alvéoles 25 et 26 se tournent le dos (figure 8). Les dimensions du parallélépipède sont arrangées de telle façon que, lorsque les vis se trouvent dans une position déterminée, elles passent librement entre les première et seconde goupilles 4 et 4' alors qu'elles se crantent par leurs première et seconde alvéoles 25 et 26 respectivement dans les première et seconde goupilles 4 et 4', quand les vis sont tournées d'un quart de tour, par exemple dans le sens des flèches E.The removable insert is illustrated in Figures 4, 8, 12 and 14 and can replace the non-removable insert illustrated in Figures 1, 5 and 9. As shown in Figures 4, 8 and 12, this insert is produced in two parts: a cover 6 of oblong shape fitting into hole 19 of cap 1 with its support flange 20 and two screws 7 and 7 ' crossing this cover 6 in the direction of the arrows B. As we clearly seen in Figures 4, 8 and 12, the screws 7 and 7 ' have a cylindrical head 31 and 31 'capable of fit in the bore 32 of the cover 6, the head being provided with a stop collar 33 and a slot 34 likely to receive a screwdriver. The upper portion 24 of each screw 7 and 7 'has the shape of a rectangular parallelepiped which is provided with first and second cells 25 and 26 as is well shown on Figures 8 and 12. These cells 25 and 26 turn the back (Figure 8). The dimensions of the parallelepiped are arranged in such a way that when the screws are located in a determined position, they pass freely between the first and second pins 4 and 4 'then that they are notched by their first and second cells 25 and 26 respectively in the first and second pins 4 and 4 ', when the screws are turned a quarter turn, for example in the direction of the arrows E.

Si l'on se reporte maintenant plus particulièrement au dispositif présenté en coupe à la figure 5 et aux éléments composant ce dispositif présentés en figure 6, on s'aperçoit que le manchon 3' (de même que le manchon 3 non représenté sur ces figures) est pourvu de première et seconde parois 17 et 18 qui font face à la paroi 40 du maillon 2, ainsi que de première et seconde parois 17' et 18' qui font face à la paroi 40' du maillon 2'. Comme on le voit bien en figure 5, ces parois 17, 17' et 18, 18' présentent une configuration - ici deux plans formant un angle obtus - limitant l'angle de rotation des maillons 2 et 2'. Ainsi on a représenté en figure 5 un maillon 2 en position extrême vers le haut, la paroi 40 du maillon 2 venant s'appuyer contre la paroi 17 du manchon 3'. A partir de cette position, le maillon 2 ne peut se mouvoir que vers le bas dans le sens de la flèche F. Cette figure montre de façon analogue un maillon 2' en position extrême vers le bas, la paroi 40' du maillon 2' venant s'appuyer contre la paroi 18' du manchon 3'. A partir de cette position, le maillon 2' ne peut se mouvoir que vers le haut, dans le sens de la flèche G. La disposition qui vient d'être décrite fait comprendre que l'angle de rotation des maillons 2 et 2' est donné par les manchons 3 et 3' de sorte que l'effort d'arrêt se porte sur les maillons 2 et 2' et nullement sur la coiffe 1 qui n'est donc pas sollicitée mécaniquement.If we now refer more particularly to the device presented in section in FIG. 5 and to components of this device presented in Figure 6, we realizes that the sleeve 3 '(as well as the sleeve 3 not shown in these figures) is provided with first and second walls 17 and 18 which face the wall 40 of the link 2, as well as first and second walls 17 'and 18 'which face the wall 40' of the link 2 '. As we clearly seen in Figure 5, these walls 17, 17 'and 18, 18' have a configuration - here two planes forming a obtuse angle - limiting the angle of rotation of the links 2 and 2 '. Thus, FIG. 5 shows a link 2 in extreme position upwards, the wall 40 of the link 2 coming to rest against the wall 17 of the sleeve 3 '. AT from this position, link 2 cannot move only down in the direction of arrow F. This figure similarly shows a 2 'link in the extreme position downwards, the wall 40 'of the link 2' coming to bear against the wall 18 'of the sleeve 3'. From this position, the 2 'link can only move towards the top, in the direction of arrow G. The arrangement which just described makes it clear that the angle of rotation of links 2 and 2 'is given by sleeves 3 and 3 'so that the stopping effort is focused on the links 2 and 2 'and not on the cover 1 which is not therefore not stressed mechanically.

Si l'on se reporte encore une fois aux figures 5 et 6, on remarque que les trous 12' et 14' percés dans les oreilles 11' et 13' des maillons 2 et 2' sont oblongs. Il en va de même pour les trous 12 et 14 percés dans les oreilles 11 et 13 non représentées ici. Les figures montrent aussi que la dimension allongée de la forme oblongue des trous est dirigée dans le sens de l'épaisseur des maillons 2 et 2'. Cette forme est importante, car on comprendra qu'en plus de la rotation du maillon autour de la goupille à laquelle il est attaché, le maillon est susceptible de se mouvoir verticalement, dans le sens de l'épaisseur du bracelet, ce qui réduit considérablement le jour entre les maillons et la coiffe qui les recouvre. Cela est illustré par la figure 5. On voit que le maillon 2 de gauche présente par rapport à la coiffe des jours à peu près égaux sur le haut et sur le bas du maillon. La goupille 4 est alors en contact avec le haut du trou oblong 12'. En ce qui concerne le maillon 2' de droite, sa partie basse touche la coiffe, alors que sa partie haute présente un jour par rapport à la coiffe qui est à peu près le double de ce qui est montré à gauche de la figure. La goupille 4' est alors en contact avec le bas du trou oblong 14'. En résumé cette disposition permet un angle de rotation maximum des maillons pour un jour minimum entre maillons et coiffe.If we refer again to Figures 5 and 6, we note that the holes 12 'and 14' drilled in the ears 11 'and 13' of the links 2 and 2 'are oblong. he the same goes for the holes 12 and 14 drilled in the ears 11 and 13 not shown here. The figures also show that the elongated dimension of the shape oblong of the holes is directed in the thickness direction links 2 and 2 '. This shape is important because will understand that in addition to the rotation of the link around the pin to which it is attached, the link is likely to move vertically, in the direction of the thickness of the bracelet, which considerably reduces the day between the links and the cap that covers them. This is illustrated in Figure 5. We see that the link 2 on the left presents in relation to the cap of the days to roughly equal on the top and bottom of the link. The pin 4 is then in contact with the top of the hole oblong 12 '. Regarding the 2 'link on the right, its lower part touches the cap, while its upper part one day compared to the cap which is about nearly double what is shown to the left of the figure. The 4 'pin is then in contact with the bottom of the hole oblong 14 '. In summary this arrangement allows an angle of maximum rotation of the links for a minimum day between links and headdress.

On va donner pour terminer quelques indications concernant le montage du dispositif d'articulation. On peut alors se référer à la figure 2. On fournit des premier et second maillons 2 et 2', des première et seconde goupilles 4 et 4', des premier et second manchons 3 et 3' et une coiffe 1. On introduit, par la gauche de la figure la goupille 4 dans l'oreille 11 jusqu'à ce qu'elle émerge assez pour y glisser les manchons 3 et 3' par leurs trous 15 et 15'. On termine l'introduction de la goupille 4 dans l'oreille 11' à travers le trou 12' de cette oreille. On approche de ce prémontage le maillon 2' pour aligner les trous 13 et 13' de ce maillon 2' avec les trous 16 et 16' des manchons 3 et 3'. On introduit la goupille 4' dans les trous ainsi alignés. On glisse sur l'assemblage ainsi réalisé la coiffe 1 jusqu'à ce que l'ouverture 19 de cette coiffe soit centré sur les goupilles 4 et 4'. Les goupilles sont alors prisonnières de la coiffe 1. Par l'ouverture 19 on pousse les manchons l'un à droite, l'autre à gauche pour qu'ils viennent en appui respectivement sur les oreilles des maillons (voir figures 1 et 9). On introduit l'insert 5 (figures 3, 7 et 11) par l'ouverture 19, jusqu'à ce que ses alvéoles 22 et 23 viennent se cranter sur les goupilles 4 et 4'. Le montage est alors terminé.We will give to finish some indications concerning the assembly of the articulation device. We can then refer to Figure 2. We provide first and second links 2 and 2 ', first and second pins 4 and 4 ', first and second sleeves 3 and 3 'and a cap 1. We introduce, by the left of the figure the pin 4 in the ear 11 until it emerges enough to slide the 3 and 3 'sleeves through their holes 15 and 15 '. We finish the introduction of the pin 4 in the ear 11 'through the hole 12' of this hear. We approach this pre-assembly with the 2 'link for align the holes 13 and 13 'of this link 2' with the holes 16 and 16 'of sleeves 3 and 3'. We introduce the pin 4 'in the holes thus aligned. We slide on the assembly thus produced the cap 1 until the opening 19 of this cap is centered on the pins 4 and 4 '. The pins are then trapped of the cap 1. Through the opening 19, the sleeves are pushed one on the right, the other on the left so that they come in support respectively on the ears of the links (see Figures 1 and 9). We insert the insert 5 (Figures 3, 7 and 11) through the opening 19, until its cells 22 and 23 lock onto the pins 4 and 4 '. The assembly is then completed.

Si l'on choisit l'autre type d'exécution d'insert, celui montré aux figures 4, 8 et 12, on commence par introduire à fond le capot 6 dans l'ouverture 19. On introduit les vis 7 et 7' dans les trous 32 du capot 6 de manière à ce que le petit côté A de ces vis passe entre les goupilles 4 et 4'. Au moyen d'un tournevis on tourne ces vis d'un quart de tour, cette action ayant pour effet de cranter les alvéoles 25 et 26 desdites vis dans les goupilles 4 et 4'. On a déjà dit que cette forme d'exécution est démontable. Il suffit pour cela de tourner les vis 7 et 7' d'un nouveau quart de tour, ce qui a pour effet de décranter les alvéoles 25 et 26 des goupilles 4 et 4', ce qui permet de retirer les vis 7 et 7', puis le capot 6.If we choose the other type of insert execution, the one shown in figures 4, 8 and 12, we start with fully insert the cover 6 into the opening 19. On introduced the screws 7 and 7 'into the holes 32 of the cover 6 of so that the short side A of these screws goes between pins 4 and 4 '. Using a screwdriver we turn these quarter-turn screws, this action having the effect notching the cells 25 and 26 of said screws in the pins 4 and 4 '. We have already said that this form of execution is removable. You just have to turn the screws 7 and 7 'of a new quarter turn, which has for effect of removing the cells 25 and 26 from the pins 4 and 4 ', which removes the screws 7 and 7', then the cover 6.

On signalera encore, voir par exemple la figure 9, que l'insert 5 (ou le capot 6) a aussi pour fonction d'empêcher les manchons 3 et 3' de se déplacer latéralement, ces manchons eux-mêmes fixant la coiffe 1. De cette manière, un jour constant peut être garanti entre la coiffe 1 et les maillons 2 et 2'.We will also indicate, see for example Figure 9, that the insert 5 (or the cover 6) also has the function prevent the 3 and 3 'sleeves from moving laterally, these sleeves themselves fixing the cover 1. In this way, a constant day can be guaranteed between cap 1 and links 2 and 2 '.
