Description

ATTACHE DE VERRE POUR ARTICLE DE LUNETTERIE, ET ARTICLE DE LUNETTERIE LA COMPORTANT GLASS FASTENER FOR EYEWEAR AND EYEWEAR COMPRISING SAME
La présente invention est relative à la lunetterie et, plus précisément, à une attache pour les verres d'articles de lunetterie.The present invention relates to eyewear and, more specifically, to a fastener for glasses of eyewear.
Le montage des verres d'articles de lunetterie se fait, de manière traditionnelle, suivant deux techniques différentes.The fitting of glasses for eyewear is done, in a traditional way, according to two different techniques.
Selon la première technique, chaque verre est enchâssé dans un anneau, dénommé cercle, qui appartient à une monture comportant, par ailleurs, un pont de liaison des deux cercles, deux plaquettes nasales et deux branches associées chacune à un cercle.According to the first technique, each lens is encased in a ring, called a circle, which belongs to a frame comprising, moreover, a bridge connecting the two circles, two nose pads and two branches each associated with a circle.
Selon la seconde technique, pour un montage plus léger, il n'existe pas de cercles, et ce sont les verres qui portent directement les plaquettes, le pont et les branches, par l'intermédiaire d'attaches qui sont fixées directement sur les verres.According to the second technique, for a lighter mounting, there are no circles, and it is the glasses which directly carry the plates, the bridge and the branches, by means of fasteners which are fixed directly on the glasses .
Actuellement, dans cette seconde technique, soit les attaches sont collées sur les verres, soit les verres sont percés pour recevoir des vis ou analogues de montage des attaches.Currently, in this second technique, either the fasteners are glued to the glasses, or the glasses are drilled to receive screws or the like for mounting the fasteners.
La fixation par collage, telle celle décrite dans le brevet US - A - 5.123.724, présente l'inconvénient qui réside en ce que les attaches sont difficilement amovibles, pour le remplacement d'un verre ou d'une autre partie de l'article, cet enlèvement présentant un risque de bris des verres. En outre, il existe un risque de débordement de colle, d'où l'obligation d'appliquer ce produit avec beaucoup de minutie.Fixing by gluing, such as that described in US patent - A - 5,123,724, has the disadvantage that the fasteners are difficult to remove, for replacing a glass or another part of the article, this removal presenting a risk of glass breakage. In addition, there is a risk of glue overflow, hence the obligation to apply this product very carefully.
La fixation par perçage des verres présente l'inconvénient qui réside en ce que, dans la zone de perçage, le verre est mécaniquement affaibli et risque de se briser. Ce risque est d'autant plus présent et accru que, avec l'usage et le temps, les vis se desserrent d'elles-mêmes progressivement et que le verre peut donc être cassé, soit lors du resserrage d'une vis, soit du fait des mouvements relatifs du verre et de l'attache lorsqu'il existe une certaine liberté entre ceux-ci.The fixing by drilling of the glasses has the disadvantage that in the drilling area, the glass is mechanically weakened and may break. This risk is all the more present and increased since, with use and over time, the screws gradually loosen themselves and the glass can therefore be broken, either when a screw is tightened or makes relative movements of the glass and the fastener when there is a certain freedom between them.
L'invention concerne cette seconde technique de montage, et elle a pour but d'en éliminer les inconvénients rappelés ci-dessus.The invention relates to this second mounting technique, and it aims to eliminate the drawbacks mentioned above.
A cet effet, l'attache de verre selon l'invention, pour article de lunetterie, destinée à être montée sur un verre présentant deux faces et un chant périphérique, est caractérisée en ce qu'elle est constituée par une pièce élastique en forme de U formant pince, dont l'âme centrale est destinée à chevaucher le chant du verre et dont les branches sont destinées à venir s'appuyer respectivement sur les faces du verre pour les serrer élastiquement.To this end, the glass fastener according to the invention, for eyewear, intended to be mounted on a glass having two faces and a peripheral edge, is characterized in that it is constituted by a piece U-shaped elastic forming a clamp, the central core of which is intended to overlap the edge of the glass and the branches of which are intended to come to bear respectively on the faces of the glass in order to tighten them elastically.
Ainsi, avec l'attache de verre selon l'invention, la liaison du verre avec au moins un autre élément de l'article de lunetterie se fait par simple pinçage mécanique élastique du verre, au voisinage de son bord périphérique. Cela permet notamment une mise en place et un enlèvement aisés de l'attache par rapport au verre, notamment sans affaiblir la résistance mécanique de celui- ci.Thus, with the glass attachment according to the invention, the connection of the glass with at least one other element of the eyewear is done by simple elastic mechanical pinching of the glass, in the vicinity of its peripheral edge. This allows in particular an easy installation and removal of the fastener relative to the glass, in particular without weakening the mechanical strength of the latter.
L'attache peut être en toute matière appropriée, par exemple en métal, notamment en acier à ressort, ou en matière plastique.The fastener can be of any suitable material, for example metal, in particular spring steel, or plastic.
En chevauchant le chant du verre, l'âme centrale du U peut être en contact ou sans contact avec ce chant.By overlapping the edge of the glass, the central core of the U can be in contact or without contact with this edge.
Suivant un mode de réalisation préféré, l'une au moins des branches du U est plane. Toutefois, de préférence également, l'une au moins des branches du U présente, en section droite, une forme convexe dont la concavité est tournée vers la face du verre avec laquelle elle coopère. Avantageusement, en section droite, l'une au moins des branches du U présente, à son extrémité libre, une rampe pour faciliter le montage de l'attache sur le verre.According to a preferred embodiment, at least one of the branches of the U is planar. However, preferably also, at least one of the branches of the U has, in cross section, a convex shape whose concavity is turned towards the face of the glass with which it cooperates. Advantageously, in cross section, at least one of the branches of the U has, at its free end, a ramp to facilitate mounting of the fastener on the glass.
Dans le cas préférentiel considéré ci-dessus, la branche plane du U est alors destinée à coopérer avec une face concave du verre, tandis que la branche convexe du U est destinée à coopérer avec une face convexe de ce verre.In the preferred case considered above, the flat branch of the U is then intended to cooperate with a concave face of the glass, while the convex branch of the U is intended to cooperate with a convex face of this glass.
Suivant une autre variante avantageuse de l'invention, l'attache comprend une protubérance qui s'étend depuis son fond sur environ le tiers de sa longueur et qui réunit partiellement les faces en vis-à-vis des branches.According to another advantageous variant of the invention, the fastener comprises a protuberance which extends from its bottom over approximately one third of its length and which partially joins the faces facing the branches.
La largeur de cette protubérance peut être inférieure ou égale à la largeur de l'attache.The width of this protuberance may be less than or equal to the width of the fastener.
L'attache selon l'invention est solidaire d'au moins un autre élément de l'article de lunetterie, soit en étant d'une seule pièce avec cet élément, soit en étant rapportée sur celui-ci, de manière fixe ou réglable. Cet élément est par exemple une branche de lunettes, un pont de liaison de deux verres, une plaquette nasale ou encore une patte coudée pour le montage amovible d'un adaptateur solaire sur des lunettes.The fastener according to the invention is integral with at least one other element of the eyewear, either by being in one piece with this element, or by being attached to it, in a fixed or adjustable manner. This element is for example a branch of glasses, a bridge connecting two glasses, a nose pad or even a bent tab for the removable mounting of a solar adapter on glasses.
La présente invention a donc également pour objet un article de lunetterie du type paire de lunettes sans cercle, caractérisé en ce qu'il est constitué de deux verres et de quatre attaches, deux extérieures et deux intérieures, chaque attache extérieure étant associée à l'une des branches de la paire de lunettes et chaque attache intérieure étant associée soit à l'une des deux extrémités du pont de liaison des deux verres, soit à une plaquette nasale.The present invention therefore also relates to an eyewear article of the pair of glasses type without a circle, characterized in that it consists of two glasses and four fasteners, two exterior and two interior, each exterior attachment being associated with the one of the branches of the pair of glasses and each interior clip being associated either with one of the two ends of the bridge connecting the two glasses, or with a nose pad.
La présente invention a pour troisième objet un article de lunetterie du type adaptateur solaire amovible, caractérisé en ce qu'il est constitué de deux verres et de quatre attaches, deux supérieures et deux inférieures, en ce que chaque attache comprend une patte qui s'étend perpendiculairement aux branches de l'attache, depuis le dos de l'âme de celle-ci, et en ce que les deux attaches supérieures sont reliées par une barre de liaison, mince et flexible, l'une desdites attaches étant solidaire de la barre tandis que l'autre attache est réglable en position sur la barre, par exemple au moyen d'une vis, afin de définir la longueur utile de la barre.A third object of the present invention is an eyewear article of the removable solar adapter type, characterized in that it consists of two glasses and four fasteners, two upper and two lower, in that each fastener comprises a tab which s extends perpendicularly to the branches of the fastener, from the back of the core thereof, and in that the two upper fasteners are connected by a connecting bar, thin and flexible, one of said fasteners being secured to the bar while the other fastener is adjustable in position on the bar, for example by means of a screw, in order to define the useful length of the bar.
La présente invention a pour quatrième objet un article de lunetterie du type adaptateur solaire amovible, caractérisé en ce qu'il est constitué de deux verres et de quatre attaches, deux latérales supérieures et deux latérales inférieures, en ce que chaque attache comprend une patte qui s'étend perpendiculairement aux branches de l'attache, depuis le dos de l'âme de celle-ci, et en ce que les deux attaches latérales supérieures sont reliées par un pont nasal flexible.The present invention has for its fourth object an eyewear article of the removable solar adapter type, characterized in that it consists of two glasses and four fasteners, two upper lateral and two lower lateral, in that each fastener comprises a tab which extends perpendicular to the branches of the fastener, from the back of the web of the latter, and in that the two upper lateral fasteners are connected by a flexible nasal bridge.
La présente invention a pour cinquième objet un article de lunetterie du type verre solaire individuel et amovible, caractérisé en ce que ledit verre comprend trois attaches, chacune de telles attaches possédant une patte qui s'étend perpendiculairement aux branches de l'attache depuis le dos de l'âme de celle-ci.The present invention has as its fifth object an eyewear article of the individual and removable solar glass type, characterized in that said glass comprises three fasteners, each of such fasteners having a tab which extends perpendicularly to the branches of the fastener from the back of its soul.
Afin de pouvoir recevoir l'attache dans sa variante prévue avec une protubérance intérieure, il est bien clair que chacun des verres de chacun des articles de lunetterie précités présente alors une encoche qui s'étend depuis la périphérie dudit verre.In order to be able to receive the fastener in its variant provided with an internal protuberance, it is very clear that each of the lenses of each of the aforesaid eyewear then has a notch which extends from the periphery of said lens.
On comprendra bien l'invention à la lecture du complément de description qui va suivre et en référence aux dessins annexés qui font partie de la description et dans lesquels :The invention will be clearly understood on reading the additional description which follows and with reference to the appended drawings which form part of the description and in which:

The glass 1 has two faces 4 and 5 and a peripheral edge 6. In general, the glass 1 is curved, its rear face 4 being concave, while its front face 5 is convex.
Selon l'invention, le verre 1 est équipé d'au moins une attache 7 qui est constituée par une pièce élastique en forme de U formant pince, dont l'âme centrale 8 est destinée à chevaucher le chant 6 du verre 1 et dont les deux branches latérales 9 et 10, bordant l'âme centrale 8, sont destinées à venir s'appuyer respectivement sur les faces 4 et 5 du verre pour les serrer élastiquement et assurer ainsi le montage élastique ferme de l'attache 7 sur le verre.According to the invention, the glass 1 is equipped with at least one fastener 7 which is constituted by an elastic U-shaped piece forming a clamp, whose central core 8 is intended to overlap the edge 6 of the glass 1 and whose two lateral branches 9 and 10, bordering the central core 8, are intended to come to bear respectively on the faces 4 and 5 of the glass to tighten them elastically and thus ensure the firm elastic mounting of the fastener 7 on the glass.
Au repos, c'est-à-dire lorsque l'attache 7 n'est pas montée sur le verre 1, la plus courte distance entre les branches 9 et 10 du U est plus faible que l'épaisseur du verre de sorte que, lors du montage de l'attache sur le verre, les branches 9 et 10 sont écartées élastiquement pour assurer leur fonction de pince.At rest, that is to say when the fastener 7 is not mounted on the glass 1, the shortest distance between the branches 9 and 10 of the U is less than the thickness of the glass so that, during mounting of the clip on the glass, the branches 9 and 10 are spaced apart elastically to ensure their function as a clamp.
L'attache 7 est en toute matière appropriée, par exemple en métal, et notamment en acier à ressort, mais il n'est pas exclu d'utiliser une autre matière convenable, par exemple une matière plastique présentant des propriétés mécaniques satisfaisantes quant à sa résistance et à son élasticité. Suivant notamment la forme que l'on donne à l'âme centrale 8 du U, le fond 22 de celle-ci est en contact avec le chant 6 du verre, ou sans contact avec lui.The fastener 7 is made of any suitable material, for example metal, and in particular spring steel, but it is not excluded to use another suitable material, for example a plastic material having satisfactory mechanical properties as to its resistance and its elasticity. According in particular to the shape which is given to the central core 8 of the U, the bottom 22 of the latter is in contact with the edge 6 of the glass, or without contact with it.
On peut donner à l'attache 7 toute forme appropriée en section droite, notamment pour des raisons d'esthétique, pour autant qu'elle puisse assurer sa fonction de pince sans dégrader mécaniquement le verre 1.The fastener 7 can be given any suitable shape in cross section, in particular for aesthetic reasons, provided that it can perform its clamp function without mechanically degrading the glass 1.
Une forme de base peut consister en un U dont l'âme et les branches latérales sont planes.A basic shape can consist of a U whose core and lateral branches are planar.
Dans l'exemple représenté à la Figure 1, la branche intérieure ou postérieure 9, c'est-à-dire celle qui appuie sur la face postérieure 4 du verre, est plane tandis que la branche extérieure ou antérieure 10, coopérant avec la face antérieure 5 du verre, présente, en section droite, une forme convexe dont la concavité est tournée vers la face 5 ; toutefois, pour faciliter le montage de l'attache sur le verre, l'extrémité libre 10a de la branche 10 présente avantageusement une concavité inversée définissant une rampe de glissement sur la face 5, lors du montage de l'attache sur le verre 1, cette rampe facilitant l'écartement des branches 9 et 10 lors du montage et évitant de rayer le verre.In the example shown in Figure 1, the inner or rear branch 9, that is to say the one which presses on the rear face 4 of the glass, is flat while the outer or front branch 10, cooperating with the face front 5 of the glass, has, in cross section, a convex shape whose concavity is turned towards the face 5; however, to facilitate mounting of the fastener on the glass, the free end 10a of the branch 10 advantageously has an inverted concavity defining a sliding ramp on the face 5, during the mounting of the fastener on the glass 1, this ramp facilitating the separation of the branches 9 and 10 during assembly and avoiding scratching the glass.
En variante, l'extrémité libre 9a de la branche 9, quelle que soit la forme de celle-ci, pourrait, dans le même but, comporter une telle rampe.As a variant, the free end 9a of the branch 9, whatever the shape of the latter, could, for the same purpose, include such a ramp.
Selon une première application, l'attache 7 selon l'invention est destinée à être solidaire d'au moins un autre élément de l'article de lunetterie, en étant, selon le cas, d'une seule pièce avec celui-ci ou rapportée sur lui, de manière fixe ou réglable.According to a first application, the fastener 7 according to the invention is intended to be integral with at least one other element of the eyewear item, by being, as the case may be, in one piece with it or attached fixed or adjustable on it.
Ainsi, pour exemple, sur la Figure 2, chaque verre 1 des lunettes 2 porte deux attaches 7 qui sont montées aux extrémités de la partie supérieure du chant 6.Thus, for example, in FIG. 2, each lens 1 of the glasses 2 carries two fasteners 7 which are mounted at the ends of the upper part of the edge 6.
Chaque attache extérieure 7 porte une branche de lunettes 11, par l'intermédiaire d'une charnière 12, tandis que les attaches intérieures 7 portent fixement un pont 13 de liaison des deux verres.Each external fastener 7 carries a branch of glasses 11, by means of a hinge 12, while the internal fasteners 7 fixedly carry a bridge 13 for connecting the two glasses.
De manière non représentée, les attaches intérieures 7 peuvent également porter des plaquettes nasales ou, en variante, des plaquettes peuvent être portées par deux autres attaches selon l'invention.Not shown, the internal fasteners 7 can also carry nose pads or, alternatively, platelets can be carried by two other fasteners according to the invention.
Comme montré sur la Figure 3, chaque verre 1 de l'adaptateur solaire amovible 3 porte deux attaches 7. Chaque verre 1 a été préalablement découpé, ou choisi identique, à la forme du verre 1 qui lui correspond sur la paire de lunettes 2, lorsque les verres ne sont pas encerclés, ou à la forme du cercle qui lui correspond sur la paire de lunettes dans le cas particulier où les verres de celle-ci sont enchâssés dans une monture à cercles. Ainsi qu'il a été représenté à la Figure 4, chacune des quatre attaches 7 porte solidairement une patte 14 pour le montage amovible de l'adaptateur 3 sur une paire de lunettes telle que celle qui est par exemple représentée sur la Figure 2, ou encore une paire de lunettes classique, à verres encerclés ou non encerclés.As shown in FIG. 3, each glass 1 of the removable solar adapter 3 carries two fasteners 7. Each glass 1 has been previously cut, or chosen to be identical, to the shape of the glass 1 which corresponds to it on the pair of glasses 2, when the lenses are not encircled, or in the shape of the circle which corresponds to it on the pair of glasses in the particular case where the lenses thereof are encased in a frame with circles. As shown in FIG. 4, each of the four fasteners 7 integrally carries a lug 14 for the removable mounting of the adapter 3 on a pair of glasses such as that which is for example shown in FIG. 2, or another classic pair of glasses, with encircled or non-encircled lenses.
A partir du dos de l'âme 8 de l'attache 7, chaque patte 14 s'étend d'abord perpendiculairement aux branches 9 et 10 de l'attache, puis elle est coudée à environ 90 degrés de façon à être parallèle aux branches 9 et 10 et à être orientée dans le même sens que lesdites branches pour pouvoir venir chevaucher le chant 6 du verre 1 correspondant de la paire de lunettes 2 en s'accrochant sur ce verre, dans l'exemple représenté sur la Figure 2, ou pour pouvoir venir chevaucher le cercle correspondant d'une paire de lunettes à monture, dans l'autre cas où les verres des lunettes sont enchâssés dans des cercles. Eventuellement, chaque patte 14 reçoit une gaine tubulaire 25 en matière plastique (représentée en pointillés à la Figure 4) destinée à protéger les verres et/ou les cercles de la monture qui va recevoir l'adaptateur 3.From the back of the core 8 of the clip 7, each tab 14 first extends perpendicularly to the branches 9 and 10 of the clip, then it is bent at about 90 degrees so as to be parallel to the branches 9 and 10 and to be oriented in the same direction as said branches so as to be able to overlap the edge 6 of the corresponding glass 1 of the pair of glasses 2 by hanging on this glass, in the example shown in FIG. 2, or in order to be able to overlap the corresponding circle with a pair of rimmed glasses, in the other case where the lenses of the glasses are set in circles. Optionally, each tab 14 receives a tubular sheath 25 of plastic material (shown in dotted lines in FIG. 4) intended to protect the lenses and / or the circles of the frame which will receive the adapter 3.
Dans l'implantation représentée sur la Figure 3, adaptable à tous les types de lunettes, chaque verre 1 de l'adaptateur comporte une attache 7 à l'extrémité extérieure du bord inférieur du verre et une attache 7 à l'extrémité extérieure du bord supérieur du verre.In the layout shown in Figure 3, adaptable to all types of glasses, each lens 1 of the adapter has a clip 7 at the outer end of the lower edge of the lens and a clip 7 at the outer end of the edge glass top.
Les attaches supérieures 7 sont reliées par une barre de liaison 15, mince et flexible, par exemple métallique, dont la longueur permet, par flexion de cette barre, d'écarter suffisamment les deux verres l'un de l'autre, et par conséquent les deux pattes inférieures 14 l'une de l'autre, pour permettre la mise en place et l'enlèvement de l'adaptateur sur la paire de lunettes 2.The upper fasteners 7 are connected by a connecting bar 15, thin and flexible, for example metallic, the length of which allows, by bending this bar, to separate the two glasses sufficiently from one another, and therefore the two lower tabs 14 from one another, to allow the adapter to be fitted and removed on the pair of glasses 2.
Le cas échéant, l'une des extrémités de la barre 15, par exemple l'extrémité gauche sur le dessin, peut être solidarisée, par exemple par soudage, à l'une des attaches supérieures 7, tandis que son autre extrémité (celle de droite sur le dessin) peut coulisser de manière réglable, par rapport à l'autre attache supérieure 7, pour le réglage de la longueur utile de cette barre. L'attache de droite est alors dotée d'un bossage 16 de forme générale cylindrique qui est soudé à l'âme 8 de l'attache 7. Ce bossage est percé d'un orifice 17 pour le passage avec un très léger jeu de la barre 15.If necessary, one of the ends of the bar 15, for example the left end in the drawing, can be secured, for example by welding, to one of the upper fasteners 7, while its other end (that of right in the drawing) can slide in an adjustable manner, relative to the other upper fastener 7, for adjusting the useful length of this bar. The right fastener is then provided with a boss 16 of generally cylindrical shape which is welded to the core 8 of the fastener 7. This boss is pierced with an orifice 17 for passage with a very slight play of the bar 15.
Une fois la longueur utile obtenue, qui définit la distance entre les deux attaches supérieures 7 en fonction de l'écartement voulu des deux verres de l'adaptateur, la barre 15 est immobilisée par rapport à cette seconde attache 7, par exemple par serrage d'une vis 18 dont la tige filetée 23 coopère avec un trou tarandé 24 percé perpendiculairement à l'âme 8 de l'attache 7 et à la direction selon laquelle la barre 15 traverse l'orifice 17 du bossage 16. Après cette immobilisation, la barre 15 est coupée légèrement au-delà de l'attache de droite.Once the useful length has been obtained, which defines the distance between the two upper fasteners 7 as a function of the desired spacing of the two lenses of the adapter, the bar 15 is immobilized relative to this second fastener 7, for example by tightening d 'a screw 18 whose threaded rod 23 cooperates with a tarand hole 24 drilled perpendicular to the core 8 of the fastener 7 and to the direction in which the bar 15 crosses the orifice 17 of the boss 16. After this immobilization, the bar 15 is cut slightly beyond the right fastener.
Comme montré sur la figure 8, chaque verre 1 de l'adaptateur solaire amovible 19 porte deux attaches 7, une latérale supérieure et une latérale inférieure. Chacune de ces attaches est du type de celle décrite précédemment, c'est à dire de l'attache dotée d'une patte 14 qui permet le montage amovible de l'adaptateur 19 sur une paire de lunettes telle celle représentée sur la figure 2, ou encore sur une paire de lunettes classique.As shown in FIG. 8, each glass 1 of the removable solar adapter 19 carries two fasteners 7, an upper side and a lower side. Each of these fasteners is of the type described above, that is to say of the fastener provided with a lug 14 which allows the removable mounting of the adapter 19 on a pair of glasses such as that shown in FIG. 2, or even on a classic pair of glasses.
Chacune des deux attaches latérales supérieures précitées est disposée fixement à l'une des deux extrémités d'un pont nasal 13 réalisé en une matière très élastique, par exemple en acier à ressort, et dont la longueur est choisie de telle sorte que, du fait de la grande flexibilité du pont 13, l'adaptateur 19 puisse être monté et maintenu élastiquement sur la paire de lunettes à équiper, en chevauchant soit les deux verres 1, dans le cas où ceux-ci ne pas pas encerclés, soit les cercles dans le cas où les verres de lunettes sont enchâssés. Les deux attaches latérales inférieures, sensiblement diamétralement opposées aux attaches supérieures, assurent une parfaite fixation de l'adaptateur 19 sur la paire de lunettes à équiper.Each of the two aforementioned upper lateral attachments is fixedly disposed at one of the two ends of a nasal bridge 13 made of a very elastic material, for example spring steel, and the length of which is chosen so that, because of the great flexibility of the bridge 13, the adapter 19 can be mounted and held resiliently on the pair of glasses to be fitted, overlapping either the two glasses 1, in the case where these are not surrounded, or the circles in the case where the spectacle lenses are set. The two lower lateral attachments, substantially diametrically opposite the upper attachments, ensure perfect attachment of the adapter 19 on the pair of glasses to be fitted.
Selon une autre application illustrée à la figure 9, les verres solaires l' et 1" sont individuels et sont dotés chacun de trois attaches 7 également pourvues chacune d'une patte 14 qui permet l'accrochage indépendant de chaque verre solaire l' et 1" sur la paire de lunettes à équiper, que celle-ci soit à verres encerclés ou non encerclés. On élimine par cette variante la barre de liaison flexible 15 de l'adaptateur 3 ou le pont nasal flexible 13 de l'adaptateur 19.According to another application illustrated in FIG. 9, the solar glasses 1 'and 1 "are individual and are each provided with three fasteners 7 also each provided with a lug 14 which allows independent hanging of each solar glass 1' and 1 "on the pair of glasses to be fitted, whether the glasses are encircled or not encircled. This variant eliminates the flexible connecting bar 15 of the adapter 3 or the flexible nasal bridge 13 of the adapter 19.
Il a été représenté sur les figures 5 à 7 deux variantes d'attache selon lesquelles le fond 22 est pourvu d'une protubérance 20 apte à coopérer avec une encoche 21 de forme congru ente pratiquée à la périphérie du verre 1. L'encoche 21 est avantageusement rectangulaire et la protubérance 20 est formée à l'intérieur de l'attache 7 depuis son fond 22 pour s'étendre sur environ le tiers de la longueur de l'attache, à l'intérieur de celle-ci.It has been shown in Figures 5 to 7 two variants of attachment according to which the bottom 22 is provided with a protuberance 20 adapted to cooperate with a notch 21 of congruent shape formed at the periphery of the glass 1. The notch 21 is advantageously rectangular and the protuberance 20 is formed inside the fastener 7 from its bottom 22 to extend over approximately one third of the length of the fastener, inside the latter.
La protubérance 20 réunit donc partiellement les deux faces vis-à-vis des branches 9 et 10 de l'attache 7.The protrusion 20 therefore partially joins the two faces with respect to the branches 9 and 10 of the fastener 7.
La protubérance 20 peut être d'une largeur inférieure à la largeur de l'attache 7 (Figures 5 et 6) ou égale à celle de l'attache 7 (Figure 7).The protrusion 20 may be of a width less than the width of the fastener 7 (Figures 5 and 6) or equal to that of the fastener 7 (Figure 7).
Si la protubérance 20 est moins large que l'attache 7, l'encoche 21 est également notablement moins large que l'attache 7 et, dans ce cas, ladite encoche est invisible sous l'attache 7 après mise en place de celle-ci sur le verre 1, l' ou 1". Si la protubérance 20 est d'une largeur égale à celle de l'attache 7 (Figure 7), elle est à peine visible de part et d'autre de ladite attache lorsque celle-ci est mise en place sur le verre 1, l' ou 1".If the protuberance 20 is less wide than the fastener 7, the notch 21 is also appreciably less wide than the fastener 7 and, in this case, said notch is invisible under the fastener 7 after its installation on glass 1, l or 1 ". If the protuberance 20 is of a width equal to that of the fastener 7 (Figure 7), it is barely visible on either side of said fastener when the latter is placed on the glass 1, l 'or 1 ".
Cette disposition encoche 21 - protubérance 20 a pour avantage d'éviter que l'attache 7 puisse pivoter sur le verre 1 après son montage sur ledit verre et, partant, qu'elle ait tendance à s'en détacher, et ce quelle que soit la largeur de la protubérance relativement à la largeur de l'attacheThis notch arrangement 21 - protuberance 20 has the advantage of preventing the fastener 7 from being able to pivot on the glass 1 after it has been mounted on the said glass and, consequently, that it tends to detach from it, whatever the width of the protrusion relative to the width of the fastener
Bien entendu, l'invention n'est pas limitée aux modes de réalisation ainsi qu'aux modes d'application qui ont été décrits ; on pourrait au contraire concevoir diverses variantes sans sortir pour autant de son cadre. Of course, the invention is not limited to the embodiments as well as to the modes of application which have been described; on the contrary, we could conceive of various variants without departing from its framework.
