Description

PAIRE DE LUNETTES DEMONTABLE Dismountable pair of glasses
La présente invention concerne une paire de lunettes démontable. Une telle paire de lunettes comporte notamment une monture et un support de verres fixés l'un à l'autre de façon amovible.The present invention relates to a removable pair of glasses. Such a pair of glasses in particular comprises a frame and a lens holder fixed to each other in a removable manner.
De tout temps les utilisateurs de lunettes ont exprimé le désir de pouvoir accorder la forme, la matière, la couleur... de leur paire de lunettes avec leurs vêtements et/ou les circonstances de leur vie quotidienne. Cependant, un tel désir est difficile à satisfaire dans la mesure où cela nécessite qu'un même utilisateur possède plusieurs paires de lunettes. Le prix souvent important des verres correcteurs limite considérablement une telle pratique.At all times, users of glasses have expressed the desire to be able to match the shape, material, color ... of their pair of glasses with their clothes and / or the circumstances of their daily life. However, such a desire is difficult to satisfy since it requires that the same user has several pairs of glasses. The often high price of corrective lenses considerably limits such a practice.
Il est déjà connu, pour pallier ces inconvénients, de réaliser une paire de lunettes en deux parties : à savoir une monture et un support de verres. Ainsi, un seul et même support de verres peut être associé à plusieurs montures de formes, matières et/ou couleurs différentes.It is already known, to overcome these drawbacks, to produce a pair of glasses in two parts: namely a frame and a lens holder. Thus, a single lens holder can be associated with several frames of different shapes, materials and / or colors.
Le brevet français FR-2.629.604 (TOFFIN) décrit une telle paire de lunettes démontable. Cependant, les moyens de fixation de la monture avec le support de verres sont complexes, multiples et difficiles à réaliser. Ces moyens nécessitent notamment pour leur réalisation un outillage spécialisé et une grande précision de fabrication.French patent FR-2,629,604 (TOFFIN) describes such a removable pair of glasses. However, the means of fixing the frame with the lens holder are complex, multiple and difficult to produce. These means require in particular for their production specialized tools and high manufacturing precision.
En vue de donner une certaine élasticité au support de verre, le nez de ce support est, en outre, réalisé en un alliage spécifique (titane et nickel) particulièrement onéreux et qui, de plus, est difficile à souder.In order to give a certain elasticity to the glass support, the nose of this support is, moreover, made of a specific alloy (titanium and nickel) which is particularly expensive and which, moreover, is difficult to weld.
De ce fait, une telle paire de lunettes n'est pas facile à réaliser et présente un coût de fabrication qui ne permet pas d'atteindre l'effet escompté. Il est ainsi toujours onéreux pour un même utilisateur de posséder plusieurs montures différentes.Therefore, such a pair of glasses is not easy to make and has a manufacturing cost which does not achieve the desired effect. It is therefore always expensive for the same user to have several different mounts.
La présente invention a pour but de pallier l'ensemble de ces inconvénients et notamment de réaliser une paire de lunettes en deux parties (monture et support de verres) ne nécessitant pas, au niveau des moyens de fixation de ces parties l'une à l'autre, de travail minutieux ou de matière onéreuse.The present invention aims to overcome all of these drawbacks and in particular to produce a pair of glasses in two parts (frame and lens holder) not requiring, at the level of the fixing means of these parts to each other, meticulous work or expensive material.
L'objectif de la présente invention est, en outre, de réaliser, en grande série, des paires de lunettes comportant deux pièces principales munies de moyens de fixation simples, efficaces, économiques et fiables.The objective of the present invention is, moreover, to produce, in large series, pairs of glasses comprising two main parts provided with simple, effective, economical and reliable fixing means.
A cet effet, la présente invention concerne une paire de lunettes démontable comportant : - une monture munie d'une paire d'emplacements pour des verres reliés par un nez de monture,To this end, the present invention relates to a removable pair of glasses comprising: - a frame provided with a pair of locations for lenses connected by a frame nose,
- un support de verres comportant deux cerclages de verres reliés par un nez de support, eta glass holder comprising two glass straps connected by a support nose, and
- des moyens de fixation amovible du support de verres sur la monture, caractérisée en ce que les moyens de fixation sont respectivement ménagés sur les nez de monture et de support, et sont constitués, d'une part, par un nez de monture présentant une face interne en saillie par rapport au plan des verres et, d'autre part, par un nez de support agencé en forme de U, chacune des branches de ce U s'emboîtant de façon élastique autour de la partie en saillie du nez de monture.- Removable fixing means for the lens holder on the frame, characterized in that the fixing means are respectively provided on the frame and support noses, and consist, on the one hand, of a frame nose having a internal face projecting from the plane of the lenses and, secondly, by a support nose arranged in the shape of a U, each of the branches of this U interlocking elastically around the projecting part of the frame nose .
Ainsi, l'emboîtement élastique du nez de support en forme de U sur le nez de monture assure une fixation correcte de ces deux pièces l'une par rapport à l'autre, de sorte que l'aspect classique d'une paire de lunettes est préservé.Thus, the elastic fitting of the U-shaped support nose on the frame nose ensures that these two parts are correctly fixed relative to each other, so that the classic appearance of a pair of glasses is preserved.
Avantageusement, l'élasticité intrinsèque du nez de monture permet une désolidarisation tout aussi aisée de ces deux pièces.Advantageously, the intrinsic elasticity of the frame nose allows an equally easy separation of these two parts.
Ainsi, l'utilisateur de lunettes peut très facilement et sans l'aide d'aucun instrument désolidariser le support de verres de la monture. Celle-ci ne présente aucune particularité, si ce n'est un nez de monture en saillie par rapport au plan des verres. De même, les emplacements de la monture, destinés à recevoir les verres, sont munis de simples épaulements classiques.Thus, the user of glasses can very easily and without the aid of any instrument detach the lens holder from the frame. It has no particular features, except a frame nose projecting from the plane of the lenses. Likewise, the locations of the frame, intended to receive the lenses, are provided with simple conventional shoulders.
Une telle monture présente ainsi l'avantage de ne pas avoir à présenter d'élasticité propre et donc de pouvoir être réalisée en n'importe quelle matière, sous t out es forme s dé s irée s . En out r e , la ré al i sat ion d ' une te ll e monture n'entraîne pas de surcoût de fabrication notable , par rapport à une monture classique. De pré fé rence , l es bran ches du U de nez de support sont inclinées l'une vers l'autre et le nez de monture est muni , sur ses parties latérales , de gorges présentant une inclinai s on corre spondant e e t adapté es pour rece voi r par e mboîtement él as tique chacune des bran ches du U de nez de monture .Such a frame thus has the advantage of not having to have its own elasticity and therefore of being able to be made of any material, under all forms are desired. In addition, the re al i sat ion of a te ll e frame does not involve any significant additional manufacturing cost, compared to a conventional frame. Preferably, the branches of the U of the support nose are inclined towards one another and the mount nose is provided, on its lateral parts, with grooves having a corresponding inclination and adapted for receive by elastic assembly each of the branches of the frame nose U.
Une telle disposition, bien qu'elle nécessite la réalisation de deux gorges latérales dans le nez de monture, permet d'améliorer la fixation du support de verres dans la monture, sans pour autant rendre plus difficile ou plus onéreuse la fabrication de cette monture.Such an arrangement, although it requires the production of two lateral grooves in the frame nose, makes it possible to improve the fixing of the lens holder in the frame, without however making the manufacture of this frame more difficult or more expensive.
Avantageusement, l'inclinaison des branches et des gorges a pour effet de plaquer naturellement le support de verres contre la monture. Ainsi, si la paire de lunettes fait l'objet d'un choc frontal ou latéral, elle a tendance à former un tout et à ne pas se dissocier, ce qui est un atout du point de vue de la sécurité. En effet, pour désolidariser le support de verres de la monture, il faut exercer une force supérieure à la force de résistance élastique des branches du U de nez de support. Cette force de résistance est suffisamment faible pour permettre une desolidarisation manuelle aisée pour un adulte, et est suffisamment forte pour solidariser le support et la monture dans tous les autres cas (chutes, chocs...).Advantageously, the inclination of the branches and the grooves has the effect of naturally pressing the lens holder against the frame. Thus, if the pair of glasses is subjected to a frontal or lateral impact, it tends to form a whole and not to dissociate, which is an advantage from the point of view of safety. Indeed, to separate the lens holder from the frame, it is necessary to exert a force greater than the elastic resistance force of the branches of the U of the support nose. This resistance force is low enough to allow easy manual detachment for an adult, and is strong enough to secure the support and the frame in all other cases (falls, shocks ...).
D'autres objets, caractéristiques et avantages de la présente invention ressortiront d'ailleurs de la description qui suit, à titre d'exemple en référence aux dessins annexés dans lesquels :Other objects, characteristics and advantages of the present invention will emerge from the description which follows, by way of example with reference to the appended drawings in which:

- la figure 5 est une vue semblable à la figure 2 montrant une variante de réalisation de l'invention.- Figure 5 is a view similar to Figure 2 showing an alternative embodiment of the invention.
Selon la forme de réalisation représentée aux figures 1 à 4, la paire de lunettes 10 selon l'invention est réalisée en deux parties principales, à savoir une monture 11 et un support de verres 12. La monture 11 est munie de deux branches latérales 13 destinées à reposer sur les oreilles d'un utilisateur. Chacune de ces branches est reliée de façon pivotante à la monture 11, par des charnières 14 de type connu. La monture 11 est, en outre, munie de deux emplacements de verres 15 reliés l'un à l'autre par un nez de monture 16. A la périphérie interne de chacun des emplacements, on trouve un épaulement 17. Le nez de monture 16 est réalisé de telle sorte que sa face interne 18 soit au moins partiellement en saillie par rapport au plan P des verres. De part et d'autre du nez de monture, on trouve en outre deux gorges latérales 30 (figures 1, 2 et 4). Le fond de ces gorges est incliné (figure 4) de sorte qu'à leur extrémité débouchant sur la face interne 18 du nez de monture l'ecartement du fond de ces gorges soit plus grand qu'en début de gorge du côté de l'épaulement 17.According to the embodiment shown in Figures 1 to 4, the pair of glasses 10 according to the invention is made in two main parts, namely a frame 11 and a lens holder 12. The frame 11 is provided with two lateral branches 13 intended to rest on the ears of a user. Each of these branches is pivotally connected to the frame 11, by hinges 14 of known type. The frame 11 is further provided with two lens locations 15 connected to each other by a frame nose 16. At the inner periphery of each of the locations, there is a shoulder 17. The frame nose 16 is made so that its inner face 18 is at least partially projecting from the plane P of the glasses. On either side of the frame nose, there are also two lateral grooves 30 (Figures 1, 2 and 4). The bottom of these grooves is inclined (FIG. 4) so that at their end opening onto the internal face 18 of the frame nose, the spacing of the bottom of these grooves is greater than at the start of the groove on the side of the shoulder 17.
La monture est réalisée en matière synthétique et/ou naturelle, et peut présenter toutes formes, dimensions et/ou couleurs. Le support de verres est constitué de deux cerclages de verres 19, de formes correspondant aux emplacements prévus dans la monture, reliés l'un à l'autre par un nez de support de verres 20, soudé à chacun des cerclages.The frame is made of synthetic and / or natural material, and can have any shape, size and / or color. The lens holder consists of two lens straps 19, of shapes corresponding to the locations provided in the frame, connected to each other by a lens holder nose 20, welded to each of the straps.
Les cerclages et le nez de support sont avantageusement réalisés en un même matériau métallique de préférence.The straps and the support nose are advantageously made of the same metallic material preferably.
Le nez de support de verres présente en plan une forme de U. Les branches 25 de ce U (figure 4) sont inclinées l'une vers l'autre. Ainsi, l'ecartement de l'extrémité de ces branches est inférieur à la longueur de la barre transversale 26 du U du nez de support. De préférence, l'ecartement des branches du U est également légèrement inférieur à la largeur du nez de monture. Le montage de telles lunettes démontables s'effectue de la manière ci-après décrite.The glass support nose has a U shape in plan. The branches 25 of this U (FIG. 4) are inclined towards one another. Thus, the spacing of the end of these branches is less than the length of the cross bar 26 of the U of the support nose. Preferably, the spacing of the branches of the U is also slightly less than the width of the frame nose. The mounting of such removable glasses is carried out in the manner described below.
Les verres 22 (correcteurs ou non) sont tout d'abord insérés de manière classique dans les cerclages de verres 19. Pour ce faire, de manière traditionnelle, la périphérie des verres présente un profil biseauté (figure 3) qui s'insère dans le cerclage 19. De manière connue, ce cerclage se fait à froid et chaque cercle emprisonne fermement chaque verre grâce à un serre-cercle 21 (figure 1).The glasses 22 (corrective or not) are first of all inserted in a conventional manner into the glass straps 19. To do this, in a traditional manner, the periphery of the glasses has a bevelled profile (FIG. 3) which is inserted into the strapping 19. In known manner, this strapping is done cold and each circle firmly traps each glass by means of a hoop 21 (FIG. 1).
La partie en forme de U du nez de support s'emboîte elastiquement autour du nez de monture 16 et maintient fermement le support de verres à l'intérieur de la monture. Lors de l'emboîtement élastique du nez de support sur le nez de monture, les branches 25 du nez de support s'écartent l'une de l'autre pour laisser passer le nez de monture. De par leur forme inclinée l'une vers l'autre, ces branches ont naturellement tendance à enserrer le nez de monture et à solidariser fermement les deux parties de la paire de lunettes. Le support de verres est alors introduit en force dans la monture 11, de sorte que chaque cerclage 19 s'appuie sur l'épaulement 17 des emplacements de verres 15.The U-shaped part of the support nose fits elastically around the frame nose 16 and firmly holds the lens holder inside the frame. During the elastic fitting of the support nose onto the frame nose, the branches 25 of the support nose move apart from one another to allow the frame nose to pass. By their inclined shape towards each other, these branches naturally tend to enclose the frame nose and firmly secure the two parts of the pair of glasses. The lens support is then forcefully inserted into the frame 11, so that each strapping 19 is supported on the shoulder 17 of the lens locations 15.
Avantageusement, le fond des gorges 30 de la monture présente une inclinaison correspondant à celle des branches du U du nez de support de verres.Advantageously, the bottom of the grooves 30 of the frame has an inclination corresponding to that of the branches of the U of the nosepiece for supporting glasses.
Ainsi, tout effort de traction vers l'extérieur du nez de support par rapport au nez de monture a tendance à solidariser encore plus fortement ces deux pièces. C'est uniquement lorsque la force de traction vers l'extérieur est suffisante pour provoquer l'ecartement des branches du U du nez de support que la desolidarisation des deux parties de la paire de lunettes est provoquée.Thus, any tensile force towards the outside of the support nose relative to the frame nose tends to join these two parts even more strongly. It is only when the traction force towards the outside is sufficient to cause the separation of the branches of the U of the support nose that the separation of the two parts of the pair of glasses is caused.
Au contraire, tant que l'effort de traction est insuffisant, celui-ci a tendance a raffermir la solidarisation du nez de support et du nez de monture.On the contrary, as long as the tensile force is insufficient, it tends to strengthen the joining of the support nose and the frame nose.
Ainsi, l'ensemble du support de verres est solidarisé à la monture. Une telle solidarisation est insoupçonnable lorsque l'on regarde la face avant de la paire de lunettes.Thus, the entire lens holder is secured to the frame. Such solidarity is unsuspected when looking at the front of the pair of glasses.
La desolidarisation du support de verres et de la monture s'effectue très aisément. L'utilisateur, en tenant la monture dans ces mains, appuie sur les verres 22. Les cerclages sont alors extraits des emplacements 15 de verres. L'utilisateur prend ensuite le nez 20 de support de verres entre ses doigts afin de séparer complètement le support de verres et la monture.The separation of the lens holder and the frame is very easy. The user, while holding the frame in these hands, presses on the lenses 22. The straps are then extracted from the locations 15 of lenses. The user then takes the lens holder nose 20 between his fingers in order to completely separate the lens holder and the frame.
Il est à noter que la monture utilisée est de type classique et ne nécessite aucune mise en forme ou élasticité particulière. Il est seulement nécessaire que la face interne du nez de monture fasse au moins partiellement saillie du plan des verres.It should be noted that the frame used is of the conventional type and does not require any particular shaping or elasticity. It is only necessary that the inner face of the frame nose protrude at least partially from the plane of the lenses.
Il est encore à noter que la forme en U du nez de support lui confère une élasticité intrinsèque telle que ce nez de support peut être réalisé en un matériau classique. Un tel nez de support est ainsi réalisé en une matière non onéreuse. De plus, il est facile à former et à souder. Ainsi, non seulement la paire de lunettes démontable selon l'invention est aisée à utiliser, mais elle est également facile à réaliser. Aucune modification importante de la monture n'est nécessaire, ni en ce qui concerne le matériau qui la compose, ni en ce qui concerne sa forme générale.It should also be noted that the U-shape of the support nose gives it intrinsic elasticity such that this support nose can be made of a conventional material. Such a support nose is thus produced from a non-expensive material. In addition, it is easy to form and weld. Thus, not only is the removable pair of glasses according to the invention easy to use, but it is also easy to produce. No significant modification of the frame is necessary, either with regard to the material of which it is composed, or with regard to its general shape.
Selon le mode de réalisation de la figure 5, il est possible de réaliser la paire de lunettes selon l'invention de manière simplifiée. A cet effet, les branches 125 du U de nez de support 120 sont droites. Aucune gorge n'est réalisée dans le nez de monture. Les moyens de fixation du support et de la monture sont simplement constitués par l'emboîtement élastique du U de support de verres autour du nez de monture en saillie par rapport au plan P des verres. Une telle fixation, associée à l'emboîtement légèrement forcé des cerclages de verres dans les emplacements de verres 15 (comme dans le mode de réalisation précédent), assure un maintien ferme du support de verres dans la monture.According to the embodiment of Figure 5, it is possible to make the pair of glasses according to the invention in a simplified manner. For this purpose, the branches 125 of the support nose U 120 are straight. No groove is made in the frame nose. The means for fixing the support and the frame are simply constituted by the elastic fitting of the lens support U around the frame nose projecting from the plane P of the lenses. Such a fixing, associated with the slightly forced interlocking of the glass straps in the lens locations 15 (as in the previous embodiment), ensures firm support of the lens holder in the frame.
Un tel mode de réalisation est particulièrement avantageux dans la mesure où il supprime les gorges 30 de la monture et les branches inclinées du U de support.Such an embodiment is particularly advantageous insofar as it eliminates the grooves 30 of the frame and the inclined branches of the U of support.
En variante (non représentée), on munit la paire de lunettes selon l'invention d'un nez de support en forme de U à branches inclinées, sans munir la monture de gorges latérales.As a variant (not shown), the pair of glasses according to the invention is fitted with a U-shaped support nose with inclined branches, without providing the frame with lateral grooves.
En variante encore (non représentée), et toujours avec un nez de support en forme de U à branches inclinées, on réalise des gorges latérales dans la monture, dont le fond n'est pas incliné.In another variant (not shown), and still with a U-shaped support nose with inclined branches, lateral grooves are made in the frame, the bottom of which is not inclined.
Chacune de ces variantes permet de réaliser une paire de lunettes démontable, munie de moyens de fixation au niveau du nez de support de verres et du nez de monture assurant une solidarisation efficace de la monture et du support de verres.Each of these variants makes it possible to produce a removable pair of glasses, provided with fixing means at the level of the lens support nose and of the frame nose ensuring effective attachment of the frame and the lens support.
Il est à noter que dans cha ue mode de réalisation ci-dessus décrit, la barre transversale 26, 126 du U du nez de support est latéralement espacée du nez de monture. Aucune gorge n'est nécessaire pour maintenir en place cette barre transversale du U de nez de support dans la monture.It should be noted that in each embodiment described above, the transverse bar 26, 126 of the U of the support nose is laterally spaced from the frame nose. No groove is necessary to hold in place this transverse bar of the support nose U in the frame.
Bien entendu, la présente invention concerne également toute variante à la portée de l'homme de l'art.Of course, the present invention also relates to any variant within the reach of ordinary skill in the art.
Notamment, les branches de monture destinées à reposer sur les oreilles de l'utilisateur peuvent être rendues solidaires du support de verres et non de la monture. In particular, the frame branches intended to rest on the ears of the user can be made integral with the lens holder and not with the frame.
