Abstract
Description
La présente invention a trait aux lunettes extra-souples sans monture. Ces lunettes extra-souples cawrennent deux verres de lunettes, un pontet reliant les deux verres de lunettes,deux plots situés sur le long du verre côté branche et deux branches non rigides. The present invention relates to extra-flexible rimless glasses. These extra-flexible glasses come with two glasses, a trigger guard connecting the two glasses, two studs located along the side of the glass and two non-rigid branches.
Les premières lunettes mises à la disposition des mal-voyants étaient des lunettes avec monture et branches frigides. La rigidité de ces lunettes étant un inconvénient, des efforts importants ont été effectués pour les rendre plus souples, mais aussi pour diminuer leur poids tout en gardant leur résistance aux mauvais traitements. The first glasses made available to the visually impaired were glasses with frames and frigid temples. The rigidity of these glasses being a drawback, significant efforts have been made to make them more flexible, but also to reduce their weight while retaining their resistance to ill-treatment.
De plus, il a fallu innover sur le plan esthétique pour adapter les lunettes à la personnalité et au gout de l'utilisateur, afin de présenter un caractère esthétique suivant l'évolution de la mode. In addition, it was necessary to innovate on the aesthetic level to adapt the glasses to the personality and taste of the user, in order to present an aesthetic character according to the evolution of fashion.
Les matières premières les plus utilisées sont des matières synthétiques, le métal, l'écaille et meme le bois. The most used raw materials are synthetic materials, metal, tortoiseshell and even wood.
On connaît également des lunettes sans monture, c:est-à-dire sans cernes ouverts ou fermés du cadre. Les branches et pontets sont directement fixés sur le verre par vissage, les vis traversant le verre à travers des alésages. Ce système présente l'avantage d'alléger les lunettes. Cependant, lors d'un effort sur les verres, au niveau des alésages, les verres cassent facilement, et beaucoup d'utilisateurs y renoncent en raison de la dépense qu'entraîne leur fréquent remplacement. Glasses without frames are also known, that is to say without open or closed rings of the frame. The arms and bridges are fixed directly to the glass by screwing, the screws passing through the glass through bores. This system has the advantage of lightening the glasses. However, during an effort on the glasses, at the bores, the glasses break easily, and many users give it up because of the expense involved in their frequent replacement.
La présente invention propose de remédier à cet inconvénient en apportant encore une diminution du poids jusqu'à obtenir une paire de lunettes de 17 g. environ. The present invention proposes to remedy this drawback by further reducing the weight until a pair of 17 g glasses is obtained. about.
Les lunettes extra-souples sans monture comprennent
- les verres,
- un pontet reliant les deux verres et collé de part et d'autre sur les parties de bord des verres,
- deux plots situés sur le long du bord des verres côté branche, ces plots étant reliés aux verres par collage,
- deux branches non rigides reliées auxdits plots, à caractère optionnel , les lunettes extrasouples comprennent un pince-nez et une équerre située sur le pontet.Extra-soft rimless glasses include
- the glasses,
- a trigger guard connecting the two glasses and glued on both sides to the edge parts of the glasses,
- two studs located along the edge of the glasses on the branch side, these studs being connected to the glasses by gluing,
- two non-rigid branches connected to said studs, optional, the extra-flexible glasses include a nose clip and a bracket located on the trigger guard.
Le pontet reliant les deux verres de lunettes est tel que les deux verres forment entre eux un angle plat et/ou un dièdre. La valeur (ou grandeur) de l'angle plat et/ou du dièdre est fonction du choix de l'opticien; valeur réglée par la forme du pontet. The trigger guard connecting the two glasses of glasses is such that the two glasses form between them a flat angle and / or a dihedral. The value (or magnitude) of the flat angle and / or the dihedral depends on the choice of the optician; value set by the shape of the trigger guard.
L'élasticité assure le maintien de l'angle après déformation temporaire. The elasticity maintains the angle after temporary deformation.
Le pontet est collé au chant du verre, ceci pour éviter d'empiéter sur le champ optique. Le collage nécessite une colle forte, du genre de ladite marque "Superglu", avec laquelle le collage peut être effectué en 10 à 20 secondes. La même colle est utilisée pour coller les autres éléments décrits ci-dessous. The trigger guard is glued to the edge of the glass, this to avoid encroaching on the optical field. Bonding requires a strong glue, of the type of the said "Superglu" mark, with which bonding can be carried out in 10 to 20 seconds. The same glue is used to glue the other elements described below.
La matière du pontet est du PVC plastifié par du phtalate de diisooctyle de ladite marque RESINOPLAST. The material of the trigger guard is PVC plasticized with diisooctyl phthalate of the said brand RESINOPLAST.
Le plot utilisé pour faire la relation brancheverre est foré selon son axe principal sur les faces les plus étroites; un canal reliant la face supérieure du plot à sa face inférieure reçoit une extrémité de la branche de façon à permettre son pivotement. The stud used to make the branch green relationship is drilled along its main axis on the narrowest faces; a channel connecting the upper face of the stud to its lower face receives one end of the branch so as to allow it to pivot.
Le plot est collé sur le long du bord du verre côté branche de façon à empiéter le moins possible sur le champ optique du verre. Cependant, c'est la surface la plus grande qui est collée de façon à présenter le plus de prise sur le verre. The stud is glued along the edge of the glass on the branch side so as to encroach as little as possible on the optical field of the glass. However, it is the largest surface which is bonded so as to present the most grip on the glass.
Le plot est en matière plastique, comme le pontet. I1 a une forme parallélépipédique, aux dimensions de 8 x 5 x 3 mm par exemple. The stud is made of plastic, like the trigger guard. It has a parallelepiped shape, with dimensions of 8 x 5 x 3 mm for example.
Les branches de lunettes sont non rigides. The branches of glasses are not rigid.
Elles sont réalisées en corde à piano de diamètre moyen de 6/10 de mm.They are made of piano wire with an average diameter of 6/10 mm.
Les extrémités des branches,côté verre, sont réalisées en fil métallique rigide, coudé, à double reprise, à angle droit, essentiellement avant et après avoir traversé le plot perforé, collé sur le verre. The ends of the branches, on the glass side, are made of rigid metal wire, bent, twice, at right angles, essentially before and after passing through the perforated stud, glued to the glass.
Les extrémités des branches ressortant des plots ont une forme de crosse de façon à ne pas abimer, lors de leur pivotement, le verre sur lequel elles pourraient frotter, et ainsi détériorer le verre. La longueur de ces extrémités saillantes des plots est de l'ordre de 2 mm. The ends of the branches protruding from the studs have the shape of a stick so as not to damage, during their pivoting, the glass on which they could rub, and thus deteriorate the glass. The length of these projecting ends of the studs is of the order of 2 mm.
La partie de la branche entourant l'oreille est gainée, avec, sur son extrémité, une goutte de résine ester méthacrylique du type de ladite marque
GLASSBOND de LOCKTITE.The part of the branch surrounding the ear is sheathed, with, on its end, a drop of methacrylic ester resin of the type of said mark
LOCKTITE GLASSBOND.
Les lunettes selon la présente invention peuvent comporter un pince-nez collé sur les champs des verres, en-dessous du pontet, soit séparé ou intégré avec le pontet. Le pince-nez est un élément de la lunette non nécessaire, mais, par sa forme, il conditionne le confort et l'exactitude optique. The glasses according to the present invention may include a nose clip glued to the fields of the glasses, below the trigger guard, either separate or integrated with the trigger guard. The nose clip is an unnecessary part of the glasses, but by its shape it conditions comfort and optical accuracy.
Sont ajoutées au pontet deux équerres collées à la partie supérieure du pontet. Ces équerres présentent l'avantage de diminuer la flexibilité du pontet. Are added to the trigger guard two brackets glued to the upper part of the trigger guard. These brackets have the advantage of reducing the flexibility of the trigger guard.
Sans elles, l'ensemble plie trop facilement.Without them, the whole thing bends too easily.
Les équerres présentent trois côtés, deux étant sensiblement orthogonaux l'un par rapport à l'autre, droits, le troisième côté ayant la forme d'une ligne courbe. The brackets have three sides, two being substantially orthogonal to each other, straight, the third side having the shape of a curved line.
Les verres de lunettes peuvent être en matière organique et/ou minérale. Pour des verres organiques plastiqug on utilise avec avantage de la colle de ladite marque SUPERGLU et de la colle de ladite marque
GLASSBOND plutôt pour des verres minéraux.The spectacle lenses can be made of organic and / or mineral material. For plastic plastic glasses, glue from said SUPERGLU brand and glue from said brand are used with advantage.
GLASSBOND rather for mineral glasses.

La figure I représente une vue d'ensemble des lunettes. On y distingue les deux verres 1 sur lesquels sont collés le pontet 2, le pince-nez 4, le plot 6 et deux équerres 5 collées sur le pontet 2. Chaque branche 3 est composée d'un fil métallique en corde de piano, la partie côté oreille étant gainée par une gaine 7, son extrémité 7 étant terminée par une goutte de résine ester méthacrylique du type de ladite marque GLASSBOND de LOCKTITE. Figure I shows an overview of the glasses. We can see the two glasses 1 on which the bridge 2 are glued, the nose clip 4, the stud 6 and two brackets 5 glued to the bridge 2. Each branch 3 is made up of a metal wire made of piano cord, the ear side part being sheathed by a sheath 7, its end 7 being terminated by a drop of methacrylic ester resin of the type of said brand GLASSBOND from LOCKTITE.
La figure 2 représente une vue arrière du pontet 2. Le pontet 2 est collé sur les champs 13 des verres 1 de façon à ne pas empiéter sur le champ optique. FIG. 2 represents a rear view of the trigger guard 2. The trigger guard 2 is glued to the fields 13 of the glasses 1 so as not to encroach on the optical field.
La figure 3 représente une vue de dessus du pontet 2 collé sur le champ 13 du verre 1. FIG. 3 represents a top view of the trigger guard 2 glued to the field 13 of the glass 1.
La figure 4 est une me de 3/4 de face du pontet. On s'aperçoit que le pontet 2 et le plot 6 sont collés sur-un même plain horizontal,de.façon à garder une analogie avec les autres lunettes. Figure 4 is a 3/4 me face of the trigger guard. We see that the trigger guard 2 and the stud 6 are glued on the same plain horizontal, de.façon to keep an analogy with other glasses.
La figure 5 représente une vue du pontet 2 et du pince-nez 4 sur les verres 1. Sur cette figure, pontet et pince-nez forment un ensemble; ils sont collés sur les champs 13 des verres 1. Cependant, comme cela a été soulevé plus haut, le pontet 2 puis le pince-nez 4 peuvent être collés sur les champs 13 des verres 1 séparément. FIG. 5 represents a view of the trigger guard 2 and the nose clip 4 on the glasses 1. In this figure, trigger guard and nose clip form an assembly; they are glued to the fields 13 of the glasses 1. However, as was raised above, the trigger guard 2 then the nose clip 4 can be glued to the fields 13 of the glasses 1 separately.
La figure 6 représente les équerres 5, collées sur le pontet 2, l'ensemble étant collé sur les champs 13 des-verres 1. La figure montre que ces équerres disposées sur les côtés orthogonaux de la partie supérieure du pontet 2 diminuent effectivement la flexibilité de l'ensemble
La figure 7 est une vue du plot 6. Le plot 6 est foré à sa face supérieure 9 et à sa face inférieure 10, créant ainsi un canal 14 par lequel passe l'extrémité de la branche 3.6 shows the brackets 5, glued to the trigger guard 2, the assembly being glued to the fields 13 of the glasses 1. The figure shows that these brackets arranged on the orthogonal sides of the upper part of the trigger guard 2 effectively reduce the flexibility from the whole
FIG. 7 is a view of the stud 6. The stud 6 is drilled on its upper face 9 and on its lower face 10, thus creating a channel 14 through which the end of the branch 3 passes.
La figure 8 est une vue du plot 6 et du verre 1 avec la branche 3 qui passe à travers le canal 14 du plot 6. On aperçoit les deux coudées 11 et 12. La coudre 12 est terminée par un bout de branche légèrement incurvée de façon à ne pas abimer le verre 1. Ce plot 6 et. la première coudée 11 délimitent l'angle d'ouverture de la branche 3. FIG. 8 is a view of the stud 6 and of the glass 1 with the branch 3 which passes through the channel 14 of the stud 6. We see the two cubits 11 and 12. The sew 12 is terminated by a slightly curved end of branch of so as not to damage the glass 1. This stud 6 and. the first cubit 11 delimit the opening angle of the branch 3.
La présente invention n'est pas limitée aux exemples des différents éléments compcsants ces lunettes. D'autres éléments peuvent être apportés dans le cadre de la présente invention qui seraient à la portée de l'homme de l'art. The present invention is not limited to the examples of the various components of these glasses. Other elements can be brought within the framework of the present invention which would be within the reach of those skilled in the art.
De plus, les moyens permettant de fabriquer le pontet, les branches, les équerres, le pince-nez ou les plots ne sont pas décrits car ils sont connus. Ils peuvent être obtenus par exemple à partir d'un moule de façon manuelle ou automatique. In addition, the means for manufacturing the trigger guard, the branches, the brackets, the nose clip or the studs are not described because they are known. They can be obtained for example from a mold manually or automatically.
