Description

Nouveau système d'attache et son application en lunetterie New fastening system and its application in eyewear
La présente invention concerne un nouveau système d'attache et son application en lunetterie notamment. US-A-5 414 907 décrit une chaîne de lunettes dans laquelle un tube extérieur coulissant librement vient refermer deux mâchoires enserrant un lien formant une boucle, le tube étant maintenu sur les mâchoires fermées grâce à un système de retenue constitué par un ressort spirale venant enserrer le lien formant une boucle. US-A-3 874 776 décrit un système d'attache pour lunettes comprenant un bracelet en matériel flexible resserré par une bride pour déterminer deux boucles, Tune de celles-ci étant entourée d'un tube.The present invention relates to a new fastening system and its application in eyewear in particular. US-A-5,414,907 describes a spectacle chain in which an freely sliding outer tube closes two jaws enclosing a loop-forming link, the tube being held on the jaws closed by a retaining system constituted by a spiral spring coming from enclose the link forming a loop. US-A-3 874 776 describes a system for attaching glasses comprising a bracelet made of flexible material tightened by a strap to determine two loops, one of these being surrounded by a tube.
L'attache entre une chaîne de lunettes et une branche de lunettes est habituellement réalisée à l'aide d'un anneau en caoutchouc dans lequel passe la branche de lunettes. Cet anneau en caoutchouc est cintré d'une bague métallique qui, en coulissant, permet de réduire le diamètre d'attache et donc de serrer la branche de lunettes. L'autre extrémité de ce même anneau est reliée à la chaîne de lunettes :The attachment between a chain of glasses and a branch of glasses is usually carried out using a rubber ring through which passes the branch of glasses. This rubber ring is curved with a metal ring which, by sliding, makes it possible to reduce the diameter of attachment and therefore to tighten the branch of glasses. The other end of this same ring is connected to the chain of glasses:
- soit, lorsque la chaîne est un cordon, par la chaîne de lunettes elle- même effectuant une boucle scellée par une agrafe et passant dans l'anneau en caoutchouc,- either, when the chain is a cord, by the eyeglass chain itself making a loop sealed with a staple and passing through the rubber ring,
- soit, lorsqu'il s'agit d'une chaîne métallique, par un anneau terminal passant à l'intérieur de l'anneau en caoutchouc.- or, in the case of a metal chain, by a terminal ring passing inside the rubber ring.
Ces systèmes d'attache constitués par une succession visible d'agrafes, de boucles, d'anneaux, de joints, de bagues sont inesthétiques. De plus le joint de serrage est inefficace pour bloquer durablement la branche de lunettes car il se desserre progressivement et il peut en résulter la perte de la paire de lunettes. En outre, si l'anneau en caoutchouc cède, il ne peut pas être facilement, ou pas du tout, remplacé. Après de longues recherches, la demanderesse a mis au point un nouveau système d'attache permettant aussi bien de libérer facilement un lien que de le bloquer de manière efficace, tout en étant esthétique, utilisable en particulier pour les chaînes de lunettes.These fastening systems constituted by a visible succession of staples, loops, rings, seals, rings are unsightly. In addition, the tightening joint is ineffective in permanently blocking the branch of glasses because it gradually loosens and this can result in the loss of the pair of glasses. Also, if the rubber ring fails, it cannot be easily, or not at all, replaced. After extensive research, the Applicant has developed a new attachment system which makes it possible to easily release a link. than to block it effectively, while being aesthetic, usable in particular for eyeglass chains.
C'est pourquoi la présente demande a pour objet un système d'attache, caractérisé en ce qu'il comprend un tube extérieur coulissant à frottement moyen ou fort, ou venant se visser, sur un élément allongé intérieur muni d'un côté d'une échancrure formant crochet pour recevoir un lien et le bloquer lorsque le tube recouvre au moins partiellement l'ouverture de l'échancrure formant crochet, le lien pouvant être libéré lorsque le tube ne recouvre pas au moins partiellement l'ouverture de l'échancrure, ledit élément allongé intérieur pouvant être relié à un lacet de l'autre côté.This is why the present application relates to a fastening system, characterized in that it comprises a sliding outer tube with medium or strong friction, or coming to be screwed, on an inner elongated element provided with one side a notch forming a hook to receive a link and blocking it when the tube at least partially covers the opening of the notch forming a hook, the link being able to be released when the tube does not at least partially cover the opening of the notch, said inner elongated member being connectable to a lace on the other side.
L'élément allongé intérieur a une double fonction. Il comprend d'un côté une échancrure formant crochet destinée à recevoir un lien, et il peut être relié à un lacet de l'autre côté. Par "lacet" l'on entend une ficelle, corde, cordon, câble, chaîne, etc...., en textile, matière plastique, métal, etc.... Il en est de même pour le lien qui, de préférence, forme une boucle.The inner elongated element has a dual function. It comprises on one side a notch forming a hook intended to receive a link, and it can be connected to a lace on the other side. By "lace" is meant a string, cord, cord, cable, chain, etc ..., in textile, plastic, metal, etc ... It is the same for the link which, preferably , forms a loop.
Le blocage du lien est obtenu par un recouvrement partiel et de préférence total de l'ouverture de l'échancrure, par le tube extérieur. Si l'on prend par exemple un lien formant une boucle de section cylindrique de diamètre de 2 mm par exemple, si seulement 1 mm ou moins de l'ouverture de l'échancrure n'est pas recouvert par le tube extérieur, le lien sera tout de même bloqué ; il le sera encore mieux par recouvrement complet.The blocking of the link is obtained by a partial and preferably total covering of the opening of the notch, by the outer tube. If we take for example a link forming a loop of cylindrical section with a diameter of 2 mm for example, if only 1 mm or less of the opening of the notch is not covered by the outer tube, the link will be still blocked; it will be even better by full recovery.
Dans ces conditions, on comprend que l'élément allongé intérieur peut prendre de nombreuses formes de réalisation. Il peut prendre par exemple la forme d'une barre ou d'un cylindre prolongé par un véritable crochet. Ce peut être également une telle barre ou cylindre, sur le côté duquel on a aménagé une échancrure et dont on a diminué les dimensions latérales au niveau de I' échancrure de manière à tenir compte de l'épaisseur du lien en vue de l'installation dans le tube extérieur.Under these conditions, it is understood that the inner elongated element can take many embodiments. It can for example take the form of a bar or a cylinder extended by a real hook. It can also be such a bar or cylinder, on the side of which a notch has been arranged and the lateral dimensions of which have been reduced at the level of the notch so as to take account of the thickness of the link for installation in the outer tube.
Comme on l'a vu ci-dessus, le blocage du lien est obtenu par la couverture partielle et de préférence totale de l'ouverture de l'échancrure formant crochet, par le tube extérieur. Ainsi, l'échancrure n'a pas nécessairement besoin d'avoir une forme générale de crochet, c'est à dire se refermant sur au moins 270° d'angle par rapport à l'axe de sa longueur puisque c'est la coopération de l'élément allongé intérieur et du tube extérieur qui procure le blocage du lien. Toutefois, dans des conditions préférentielles de réalisation, l'échancrure formant crochet a une forme capable de bloquer le lien en l'absence du tube extérieur, lorsque l'on exerce une traction longitudinale sur celui-ci. L'évidement peut donc dans certains cas ne former crochet que parce que le tube constitue en fait une partie du crochet, fermant celui-ci en une boucle fermée ou presque. Toutefois, dans des conditions préférentielles de réalisation, notamment pour faciliter le montage, l'évidement formant crochet est capable de bloquer le lien en l'absence de tube extérieur lorsque l'on exerce une traction longitudinale sur celui-ci. En d'autres termes, le crochet joue son rôle de crochet de manière autonome, à la manière d'un hameçon ou d'un crochet de grue.As seen above, the blocking of the link is obtained by the partial and preferably total coverage of the opening of the notch forming a hook, by the outer tube. So the notch doesn't necessarily need to have a general hook shape, that is to say closing over at least 270 ° of angle relative to the axis of its length since it is the cooperation of the inner elongated element and the outer tube which provides link blocking. However, under preferential conditions of embodiment, the notch forming a hook has a shape capable of blocking the link in the absence of the outer tube, when a longitudinal traction is exerted on it. The recess can therefore in certain cases form a hook only because the tube in fact constitutes a part of the hook, closing the latter in a closed loop or almost. However, under preferential conditions of embodiment, in particular to facilitate mounting, the hook-shaped recess is capable of blocking the link in the absence of an external tube when a longitudinal traction is exerted on it. In other words, the hook plays its hook role independently, like a hook or a crane hook.
La position relative du tube extérieur par rapport à l'élément allongé intérieur (position "fermée") peut être maintenue par un frottement moyen ou fort du tube extérieur sur l'élément allongé intérieur. Ce frottement peut être obtenu par tout moyen connu de l'état de la technique. Il peut être obtenu notamment soit par contact du tube extérieur sur l'élément allongé intérieur, du tube sur le lien, ou encore du tube sur un élément intermédiaire. Dans le premier cas, on peut choisir par exemple un élément allongé intérieur cylindrique, le tube extérieur étant également de forme cylindrique, le diamètre extérieur de l'élément allongé étant presque égal au diamètre intérieur du tube extérieur de telle sorte qu'ils frottent l'un sur l'autre.The relative position of the outer tube relative to the inner elongated member ("closed" position) can be maintained by medium or strong friction of the outer tube on the inner elongated member. This friction can be obtained by any means known from the state of the art. It can be obtained in particular either by contacting the outer tube on the inner elongate element, the tube on the link, or the tube on an intermediate element. In the first case, one can choose for example an elongated cylindrical inner element, the outer tube also being of cylindrical shape, the outer diameter of the elongate element being almost equal to the inner diameter of the outer tube so that they rub the 'one over the other.
Dans un autre mode de réalisation, l'élément allongé porte à une extrémité un élément formant crochet, et c'est cet élément formant crochet qui coulisse en frottant à l'intérieur du tube extérieur, l'autre extrémité étant plus libre. Un exemple d'une telle réalisation met en jeu un crochet de forme classique, c'est à dire dont la partie crochet a une forme générale circulaire dont le diamètre est par exemple soit celui de l'intérieur d'un tube extérieur cylindrique ou de la diagonale d'un tube extérieur dont l'intérieur a une section transversale carrée. Dans encore un autre mode de réalisation, illustré dans les figures, le frottement est obtenu à l'aide d'un élément intermédiaire. Cet élément intermédiaire peut être par exemple un joint tel qu'un joint torique installé dans une rainure ménagée sur l'élément allongé intérieur. Cet élément intermédiaire peut aussi être par exemple une vis installée radialement dans le tube extérieur, et venant prendre appui sur l'élément allongé intérieur. Selon le degré de vissage de la vis, un frottement plus ou moins fort est obtenu, voire un blocage complet du coulissement. Bien entendu on peut installer plusieurs, par exemple deux joints toriques ce qui offre les avantages d'augmenter le frottement et de maintenir l'axe de l'élément allongé intérieur dans l'axe du tube extérieur.In another embodiment, the elongate element carries at one end a hook element, and it is this hook element which slides by rubbing inside the outer tube, the other end being freer. An example of such an embodiment involves a hook of conventional shape, that is to say of which the hook part has a generally circular shape whose diameter is for example either that of the inside of a cylindrical outer tube or of the diagonal of an outer tube whose interior has a square cross section. In yet another embodiment, illustrated in the figures, the friction is obtained using an intermediate element. This intermediate element can for example be a seal such as an O-ring installed in a groove formed on the inner elongate element. This intermediate element can also be for example a screw installed radially in the outer tube, and coming to bear on the inner elongated element. Depending on the degree of screwing of the screw, more or less strong friction is obtained, or even complete blocking of the sliding. Of course, it is possible to install several, for example two O-rings, which offers the advantages of increasing friction and of maintaining the axis of the inner elongated element in the axis of the outer tube.
Dans encore un autre mode de réalisation, l'intérieur du tube extérieur coulissant est muni d'un filetage, de même que tout ou partie de la surface extérieure de l'élément allongé intérieur. Le vissage du tube extérieur sur l'élément allongé intérieur procure le recouvrement de l'ouverture de l'échancrure formant crochet.In yet another embodiment, the interior of the outer sliding tube is provided with a thread, as is all or part of the outer surface of the inner elongate member. The screwing of the outer tube on the inner elongate member provides the covering of the opening of the notch forming a hook.
On peut également combiner filetage et frottement, ce dernier limitant l'auto-dévissage.You can also combine threading and friction, the latter limiting self-unscrewing.
On comprend donc bien que l'élément allongé intérieur peut prendre de nombreuses formes de réalisation, tout en respectant la caractéristique essentielle de l'invention qui est la coopération entre l'élément allongé intérieur et le tube extérieur de telle sorte que, soit par vissage, soit par frottement moyen ou fort, le tube extérieur puisse venir recouvrir l'ouverture de l'échancrure formant crochet. Ainsi par exemple la section transversale de l'élément allongé intérieur pourra être carrée, parallélépipédique, hexagonale, octogonale, et de préférence circulaire.It is therefore clear that the inner elongated element can take many embodiments, while respecting the essential characteristic of the invention which is the cooperation between the inner elongated element and the outer tube so that, either by screwing , either by medium or strong friction, the outer tube can cover the opening of the notch forming a hook. Thus, for example, the cross section of the inner elongate element may be square, parallelepiped, hexagonal, octagonal, and preferably circular.
La présente demande a donc pour objet un système d'attache ci- dessus caractérisé en ce que la section transversale de l'intérieur du tube et de l'extérieur de l'élément allongé conduit à des formes analogues, telles que carrée, ronde ou hexagonale. Si les dimensions latérales maximales de l'élément allongé intérieur doivent respecter les dimensions intérieures du tube extérieur, les dimensions minimum latérales de l'élément allongé intérieur ne sont pas critiques, étant donné par exemple que le frottement peut être obtenu à l'aide d'un élément intermédiaire tel qu'un joint torique. C'est pourquoi par exemple un élément allongé intérieur en forme d'hameçon peut être tout à fait envisageable. C'est pourquoi la présente demande a pour objet un système d'attache ci-dessus, caractérisé en ce que le tube extérieur est coulissant et en ce que le frottement du tube extérieur sur l'élément allongé est obtenu par l'ajustement des dimensions extérieures de l'élément allongé et intérieures du tube. La présente demande a aussi pour objet un système d'attache ci- dessus caractérisé en ce que le frottement du tube extérieur sur l'élément allongé est obtenu par l'installation d'un élément intermédiaire, tel un joint torique ou équivalent installé dans une rainure dont est muni l'élément allongé, ou encore une vis de blocage. La présente demande a encore pour objet un système d'attache ci- dessus caractérisé en ce que le frottement du tube extérieur sur l'élément allongé est obtenu par l'ajustement des dimensions du lien et de l'élément allongé par rapport aux dimensions intérieures du tube extérieur, de telle sorte que le lien frotte l'intérieur du tube extérieur. Par un "frottement moyen ou fort", l'on entend un frottement tel qu'un être humain a une force suffisante pour produire un déplacement relatif des deux pièces avec un effort modéré, l'objectif étant de bien bloquer le lien, tout en permettant son déblocage en mettant en oeuvre des moyens raisonnables.The present application therefore relates to a fastening system above characterized in that the cross section of the inside of the tube and the outside of the elongated element leads to similar shapes, such as square, round or hexagonal. If the maximum lateral dimensions of the inner elongated member must comply with the inner dimensions of the outer tube, the dimensions lateral minimums of the inner elongated element are not critical, since for example the friction can be obtained using an intermediate element such as an O-ring. This is why, for example, an internal elongated hook-shaped element may be entirely possible. This is why the present application relates to a fastening system above, characterized in that the outer tube is sliding and in that the friction of the outer tube on the elongated element is obtained by adjusting the dimensions outside of the elongated member and inside of the tube. The present application also relates to a fastening system above characterized in that the friction of the outer tube on the elongated element is obtained by the installation of an intermediate element, such as an O-ring or equivalent installed in a groove with which the elongate element is provided, or else a locking screw. The present application also relates to a fastening system above characterized in that the friction of the outer tube on the elongated element is obtained by adjusting the dimensions of the link and the elongated element relative to the internal dimensions of the outer tube, so that the tie rubs inside the outer tube. By "medium or strong friction" is meant friction such that a human being has sufficient force to produce a relative displacement of the two parts with moderate effort, the objective being to block the link well, while allowing its release by implementing reasonable means.

Dans des conditions préférentielles de réalisation, l'élément allongé intérieur est prolongé par un lacet du côté opposé au lien.In preferred embodiments, the inner elongated element is extended by a lace on the side opposite the link.
Dans d'autres conditions préférentielles de réalisation, l'élément allongé intérieur comprend un élément cylindrique, évidé à l'une de ses extrémités pour recevoir un lacet fixé par exemple par collage ou encore bloqué par une vis installée radialement, ou encore pincé, ledit élément cylindrique comportant une rainure dans laquelle est installé un joint torique, tandis qu'à l'extrémité de l'élément allongé opposée à celle qui reçoit le lacet est ménagée une échancrure de section en forme de crochet dans laquelle peut venir se placer un lien. Un exemple d'une telle réalisation est illustré ci-après dans les figures. Le lien peut être de tout type, ouvert ou fermé pour former une boucle.In other preferred embodiment conditions, the inner elongated element comprises a cylindrical element, hollowed out at one of its ends to receive a lace fixed for example by gluing or even blocked by a screw installed radially, or even pinched, said cylindrical element having a groove in which an O-ring is installed, while at the end of the elongated element opposite to that which receives the lace, a notch of section in the form of a hook is formed in which a link can be placed .

Its length will preferably be less than 20 cm, in particular less than 5 cm, particularly less than 3 cm.
Si, comme on l'a vu, les formes en section intérieure du tube extérieur et extérieure de l'élément allongé intérieur, ne sont pas critiques en elles-mêmes, dans les conditions définies ci-dessus, dans des conditions préférentielles de réalisation, la section transversale de l'intérieur du tube et de l'extérieur de l'élément allongé conduit à des formes analogues telles que carrées, rondes ou hexagonales de préférence. Dans des conditions tout particulièrement préférées, le tube extérieur est un tube cylindrique, et les sections transversales de l'élément allongé intérieur sont circulaires.If, as we have seen, the shapes in the inner section of the outer and outer tube of the inner elongated element are not critical in themselves, under the conditions defined above, under preferential conditions of embodiment, the cross section of the inside of the tube and the outside of the elongated element leads to similar shapes such as square, round or hexagonal preferably. In very particularly preferred conditions, the outer tube is a cylindrical tube, and the cross sections of the inner elongate member are circular.
Un système d'attache préféré selon l'invention est caractérisé en ce que l'élément allongé est prolongé par un lacet du côté opposé à celui qui reçoit un lien. Comme on l'a vu, ce lacet peut être de tout type, textile, métallique, plastique ou autre et peut être fixé par toute manière connue, par collage, vissage, sertissage, nouage, etc. Dans la mesure où l'une des applications importantes de l'invention concerne la lunetterie, on préfère des systèmes d'attache selon l'invention caractérisés en ce qu'ils comprennent en outre un lien installé dans l'évidement formant crochet, notamment un lien formant une boucle, de préférence de type joint torique. Ce lien peut être en tout matériau non rigide par exemple cuir, textile, mais de préférence matière plastique ou caoutchouc.A preferred fastening system according to the invention is characterized in that the elongated element is extended by a lace on the side opposite to that which receives a link.

This link can be made of any non-rigid material, for example leather, textile, but preferably plastic or rubber.
La présente demande a aussi pour objet un système d'attache ci- dessus caractérisé en ce qu'il comprend en outre un lien installé dans l'échancrure formant crochet.The present application also relates to a fastening system above characterized in that it further comprises a link installed in the notch forming a hook.
La présente demande a enfin pour objet une chaîne de lunettes comportant un système d'attache ci-dessus.The present application finally relates to a chain of glasses comprising a fastening system above.
L'invention sera mieux comprise si l'on se réfère aux dessins annexés sur lesquels : la figure 1 représente une vue en coupe d'un système d'attache selon l'invention mettant en jeu un tube extérieur coulissant à frottement moyen ou fort sur un élément allongé intérieur par l'intermédiaire d'un élément intermédiaire qui est un joint torique, ledit système étant en position desserrée, la branche de lunettes étant dans ce cas représentée verticalement à la droite de la figure.The invention will be better understood if reference is made to the appended drawings in which: FIG. 1 represents a sectional view of a fastening system according to the invention involving a sliding external tube with medium or strong friction on an inner elongated element by means of an intermediate element which is an O-ring, said system being in the released position, the spectacle arm being in this case shown vertically to the right of the figure.
La figure 2 est une figure analogue mais après une rotation de 90° de l'ensemble, la branche de lunettes étant dans ce cas représentée horizontalement.Figure 2 is a similar figure but after a 90 ° rotation of the assembly, the spectacle branch being in this case shown horizontally.
La figure 3 est une figure analogue à celle de la figure 1 mais en position resserrée.Figure 3 is a figure similar to that of Figure 1 but in the constricted position.
La figure 4 est une figure analogue à la figure 2, mais dans laquelle le frottement du tube extérieur coulissant sur l'élément allongé est obtenu par l'ajustement des dimensions relatives à la fois de l'élément allongé et de l'intérieur du tube, et du lien vis à vis de l'élément allongé intérieur. En référence à la figure 1 , le système de l'invention comporte un tube cylindrique extérieur 1 coulissant sur un élément allongé intérieur cylindrique 2. L'élément allongé intérieur 2 comporte :Figure 4 is a figure similar to Figure 2, but in which the friction of the sliding outer tube on the elongated member is obtained by adjusting the relative dimensions of both the elongated member and the interior of the tube , and of the link with respect to the inner elongated element. With reference to FIG. 1, the system of the invention comprises an external cylindrical tube 1 sliding on an elongated internal cylindrical element 2. The internal elongated element 2 comprises:
- un emplacement évidé 3 pour le lacet constituant la chaîne de lunettes 6,- a recessed location 3 for the lace constituting the spectacle chain 6,
- une rainure 4 pour un joint torique 5,- a groove 4 for an O-ring 5,
- une échancrure formant crochet 6 pour loger un lien 7 qui sert d'attache pour une branche de lunettes 8. A l'intérieur du lien 7 fermé en boucle passe la branche de lunettes 8 qui se loge dans l'ouverture de l'échancrure formant crochet 6. L'échancrure formant crochet 6 est capable de bloquer le lien 7 en l'absence de tube extérieur lorsque l'on exerce une traction longitudinale sur celui-ci, c'est à dire que le crochet joue son rôle de crochet de manière autonome, à la manière d'un hameçon ou d'un crochet de grue. A l'autre extrémité de l'élément allongé intérieur 2, se fixe la chaîne de lunettes 9 (par exemple par collage). Au milieu de l'élément allongé intérieur 2, se loge dans la rainure 4 un joint torique en caoutchouc 5, ceinturant cet élément allongé intérieur 2. Le tout est placé dans un tube extérieur 1 d'une longueur supérieure à celle de l'élément allongé intérieur 2, et d'un diamètre suffisamment petit pour qu'en coulissant, il frotte sur le joint torique 5 et en outre sur le lien 7 grâce à l'ajustement des dimensions de cette extrémité de l'élément allongé intérieur 2, par rapport au diamètre du lien 7 et au diamètre intérieur du tube extérieur 1. Le joint 5 et le lien 7 et l'augmentation de la surface du frottement rendent ainsi le système de blocage plus performant. De plus, le tube extérieur 1 a l'avantage de cacher l'élément allongé intérieur 2, ce qui permet un ensemble plus esthétique.- A notch forming a hook 6 to accommodate a link 7 which serves as a fastening for a branch of glasses 8. Inside the link 7 closed in a loop passes the branch of glasses 8 which is housed in the opening of the notch forming a hook 6. The notch forming a hook 6 is capable of blocking the link 7 in the absence of an external tube when a longitudinal traction is exerted on it, that is to say that the hook plays its role of hook independently, like a hook or crane hook. At the other end of the inner elongate element 2, the chain of glasses 9 is fixed (for example by gluing). In the middle of the inner elongated element 2, a rubber O-ring 5 is housed in the groove 4, encircling this inner elongated element 2. The whole is placed in an outer tube 1 of a length greater than that of the element elongated interior 2, and of a sufficiently small diameter so that by sliding, it rubs on the O-ring 5 and in addition on the link 7 thanks to the adjustment of the dimensions of this end of the interior elongated element 2, by relative to the diameter of the link 7 and to the inside diameter of the outer tube 1. The seal 5 and the link 7 and the increase in the friction surface thus make the blocking system more efficient. In addition, the outer tube 1 has the advantage of hiding the inner elongate element 2, which allows a more aesthetic whole.
En tirant sur la chaîne de lunettes 9 d'une main et en tenant le tube extérieur 1 de l'autre main, on parvient ainsi à rentrer le lien 7 dans le tube extérieur 1. La figure 3 montre que le coulissement prend fin lorsque la branche de lunettes 8 est plaquée contre le tube extérieur 1 par le lien 7. Cette position demeure stable grâce au frottement qui freine le mouvement inverse. En tenant la branche de lunettes 8 d'une main et en tirant sur le tube extérieur 1 de l'autre main, on parvient ainsi à desserrer le système d'attache.By pulling the chain of glasses 9 with one hand and holding the outer tube 1 with the other hand, we thus manage to re-enter the link 7 in the outer tube 1. FIG. 3 shows that the sliding ends when the spectacle arm 8 is pressed against the outer tube 1 by the link 7. This position remains stable thanks to the friction which brakes the reverse movement. Taking the branch of glasses 8 with one hand and by pulling on the outer tube 1 with the other hand, we thus manage to loosen the fastening system.
A titre d'exemple non limitatif, le tube extérieur 1 ci-dessus représenté a des dimensions de l'ordre de 15 mm pour la longueur et de 4 mm pour le diamètre. Le lien 7 est un joint torique qui a une longueur de 2,5cm pour un diamètre de section de 2 mm.By way of nonlimiting example, the outer tube 1 above shown has dimensions of the order of 15 mm for the length and 4 mm for the diameter. The link 7 is an O-ring which has a length of 2.5 cm for a section diameter of 2 mm.
Le système d'attache selon l'invention est particulièrement destiné à tenir plus efficacement et plus esthétiquement la chaîne de lunettes 9 sur une branche de lunettes 8. Bien entendu, l'élément allongé intérieur 2 peut être plus ajusté au tube extérieur 1 pour éviter un débattement axial, si désiré jusqu'à frotter sur toute leur longueur.The attachment system according to the invention is particularly intended to hold the spectacle chain 9 more efficiently and more aesthetically on a spectacle branch 8. Of course, the inner elongated element 2 can be more adjusted to the outer tube 1 to avoid axial travel, if desired, until rubbing over their entire length.
Sur la figure 4, variante de la figure 2 mais en position "fermée", le frottement est obtenu grâce à l'ajustement du diamètre extérieur de l'élément allongé intérieur 2 par rapport au diamètre intérieur du tube extérieur 1. Un filetage du tube extérieur 1 et de l'élément allongé intérieur 2 éventuellement combiné à un frottement du tube extérieur 1 sur le lien 7 est également une forme de réalisation préférée. En outre, cette variante comporte un blocage de l'élément allongé intérieur 2 par une vis 10 installée radialement. Une installation de vis analogue au niveau de l'emplacement évidé 3 permet de bloquer la chaîne de lunettes 9 sans pinçage ou collage et de la remplacer facilement.In FIG. 4, a variant of FIG. 2 but in the "closed" position, the friction is obtained by adjusting the outside diameter of the inner elongated element 2 relative to the inside diameter of the outside tube 1. A thread of the tube exterior 1 and the elongated interior element 2 possibly combined with friction of the exterior tube 1 on the link 7 is also a preferred embodiment. In addition, this variant comprises a blocking of the inner elongate element 2 by a screw 10 installed radially. An analogous screw installation at the recessed location 3 makes it possible to block the spectacle chain 9 without pinching or gluing and to replace it easily.
Une telle chaîne de lunettes se prête à de nombreuses variantes notamment dans l'industrie des articles de luxe. Such a chain of glasses lends itself to many variants, particularly in the luxury goods industry.
