La présente invention a pour objet un procédé d'assemblage des verres sur une monture de lunettes, et des lunettes obtenues par la mise en oeuvre dudit procédé. The subject of the present invention is a method of assembling glasses on a spectacle frame, and glasses obtained by implementing said method.
De manière traditionnelle, les verres d'une paire de lunettes sont montés enchâssés dans une monture qui peut être métallique ou en matière plastique ou analogue. Traditionally, the lenses of a pair of glasses are mounted encased in a frame which may be metallic or plastic or the like.
Dans un but initialement de gain de poids et d'économie, puis plus tard d'esthétique, il a été proposé de réduire les dimensions de la monture. Dans un premier temps les cerclages dans lesquels sont enchâssés les verres ont été supprimés, en sorte que ces derniers ne soient maintenus que par leur bord supérieur au moyen d'une traverse reliant les charnières des deux branches et incorporant le pont. Puis dans une évolution plus récente, n'ont été conservés de la monture que les éléments indispensables que sont le pont et les pivots branches, solidarisés directement auxdits verres par des procédés divers. With the aim initially of saving weight and saving, then later of aesthetics, it has been proposed to reduce the dimensions of the frame. Initially the straps in which the glasses are embedded have been removed, so that the latter are only held by their upper edge by means of a crosspiece connecting the hinges of the two branches and incorporating the bridge. Then in a more recent evolution, only the essential elements that are the bridge and the pivots have been kept of the frame, fixed directly to said glasses by various methods.
Le procédé le plus fréquemment utilisé consiste à solidariser le pont et les pivots aux verres au moyen de vis, vissées soit dans la tranche, soit dans l'une ou l'autre des faces de ceux-ci. Les lunettes construites selon ce procédé présentent l'inconvénient d'être très fragiles, et on observe en effet fréquemment une rupture du verre au niveau des alésages taraudés qui y sont pratiqués. The most frequently used method consists in securing the bridge and the pivots to the glasses by means of screws, screwed either in the edge, or in one or the other of the faces thereof. Spectacles constructed according to this method have the drawback of being very fragile, and indeed there is frequently a break in the glass at the tapped bores which are formed there.
Pour pallier cet inconvénient, il a été proposé de solidariser le pont et/ou les pivots par collage, on connaît ainsi par le document FR 1.283.283 des lunettes comportant une monture métallique comprenant un pont prolongé de part et d'autre par deux extensions logées chacune entre deux pièces en matière plastique dont l'une est munie d'une charnière tandis que l'autre est collée sur la tranche supérieure d'un verre. To overcome this drawback, it has been proposed to secure the bridge and / or the pivots by gluing, we thus know from document FR 1,283,283 glasses comprising a metal frame comprising a bridge extended on either side by two extensions each housed between two plastic parts, one of which is fitted with a hinge while the other is glued to the upper edge of a glass.
Les lunettes telles que décrites dans ce document qui est relativement vieux, présentent une esthétique discutable actuellement, par ailleurs ces lunettes, du fait de leur complexité ne sont pas économiquement rentables. The glasses as described in this document which is relatively old, present a questionable aesthetic at present, moreover these glasses, because of their complexity are not economically profitable.
En outre, on a toutefois constaté des problèmes de désolidarisation par un effet de cisaillement du joint de colle In addition, however, there have been problems of separation by a shear effect of the adhesive joint.
<Desc/Clms Page number 2><Desc / Clms Page number 2>
dû aux coefficients de dilatation différents des matériaux assemblés, à savoir le verre et la matière plastique. due to the different expansion coefficients of the assembled materials, namely glass and plastic.
On connaît également par le document FR 2.624.278, des lunettes qui comportent un pont réalisé en matière plastique, collé sur la tranche des verres, ainsi que deux plots également en matière plastique, chacun collé à proximité du bord extérieur d'un verre, sur la face intérieure de celui-ci, et percé d'un canal destiné à recevoir l'extrémité d'une branche tout en permettant le pivotement de celle-ci. Document FR 2,624,278 also discloses glasses which include a bridge made of plastic material, glued to the edge of the glasses, as well as two studs also made of plastic material, each glued near the outer edge of a glass, on the inner face of the latter, and pierced with a channel intended to receive the end of a branch while allowing the latter to pivot.
La solidarisation par collage du pont et des plots de fixation des branches en matière plastique sur les verres, lorsque ceux-ci sont des verres organiques plastiques, permet de résoudre partiellement l'inconvénient évoqué précédemment d'effet de cisaillement du joint de colle, puisque les éléments à coller sont de natures approchantes. The joining by bonding of the bridge and the studs for fixing the plastic branches on the glasses, when these are plastic organic glasses, makes it possible to partially solve the drawback mentioned previously of the shear effect of the adhesive joint, since the elements to be glued are of a similar nature.
Toutefois, le procédé de fabrication utilisé ne permet d'obtenir des lunettes de conception robuste, il est vrai qu'il est destiné à la fabrication de lunettes extra-souples et légères. On notera à cet effet le caractère rudimentaire du mode de fixation des branches, dans lequel la friction du métal sur la matière plastique génère à la longue une usure de ladite matière plastique. However, the manufacturing process used does not make it possible to obtain glasses of robust design, it is true that it is intended for the manufacture of extra-flexible and light glasses. Note for this purpose the rudimentary nature of the mode of attachment of the branches, in which the friction of the metal on the plastic generates in the long run wear of said plastic.
Par ailleurs, la souplesse des lunettes ainsi réalisées, du fait notamment que le pont soit réalisé en matière plastique, est incompatible avec l'exactitude optique qui nécessite une certaine rigidité. Furthermore, the flexibility of the glasses thus produced, in particular because the bridge is made of plastic, is incompatible with optical accuracy which requires a certain rigidity.
En outre, les éléments à coller n'étant pas exactement de même nature, il convient de choisir une colle qui convienne à coller les matériaux dont sont faits ces éléments. In addition, since the elements to be bonded are not exactly of the same nature, an adhesive should be chosen which is suitable for bonding the materials from which these elements are made.
La présente invention a pour but de proposer un procédé d'assemblage des verres sur une monture de lunettes permettant de remédier aux divers inconvénients précités. The object of the present invention is to propose a method of assembling the lenses on a spectacle frame making it possible to remedy the various aforementioned drawbacks.
Le procédé d'assemblage des verres sur une monture de lunettes selon l'invention se caractérise essentiellement en ce qu'il consiste à surmouler au moins les parties des éléments destinées à venir au contact des verres, au moyen d'un matériau The method of assembling the lenses on a spectacle frame according to the invention is essentially characterized in that it consists in overmolding at least the parts of the elements intended to come into contact with the lenses, by means of a material.
<Desc/Clms Page number 3><Desc / Clms Page number 3>
analogue à celui dont sont constitués lesdits verres, puis à réaliser le collage desdites parties sur ces derniers. similar to that of which said glasses are made, and then bonding said parts thereon.
Les éléments à coller étant de même nature, il ne se produit pas d'effet de cisaillement dû à des différences de coefficient de dilatation. Since the elements to be bonded are of the same nature, there is no shearing effect due to differences in the coefficient of expansion.
D'autre part, le collage est efficace puisque la colle est adaptée au collage d'un matériau unique. On the other hand, bonding is effective since the adhesive is suitable for bonding a single material.
Selon une caractéristique additionnelle du procédé selon l'invention, on surmoule uniquement les deux extrémités du pont qui est réalisé en métal. According to an additional characteristic of the method according to the invention, only the two ends of the bridge which is made of metal are overmolded.
Selon une autre caractéristique additionnelle du procédé selon l'invention, on surmoule uniquement les parties des charnières destinées à venir au contact des verres. According to another additional characteristic of the process according to the invention, only the parts of the hinges intended to come into contact with the glasses are overmolded.
Selon une autre caractéristique additionnelle du procédé selon l'invention, les verres ainsi que la matière de surmoulage sont en polycarbonate. According to another additional characteristic of the method according to the invention, the glasses as well as the molding material are made of polycarbonate.
La présente invention a également pour objet des lunettes obtenues par la mise en oeuvre du procédé selon l'invention, et qui se caractérisent essentiellement en ce qu'elles comportent deux verres reliés par un pont dont au moins les extrémités destinées à venir au contact desdits verres, ainsi qu'au moins les parties des charnières destinées à venir au contact desdits verres, sont surmoulées d'un matériau identique à celui dont sont faits lesdits verres, la solidarisation desdites parties surmoulées auxdits verres étant réalisée par un joint d'une colle adaptée à coller ledit matériau. The present invention also relates to glasses obtained by implementing the method according to the invention, and which are essentially characterized in that they comprise two glasses connected by a bridge, at least the ends of which are intended to come into contact with said glasses. glasses, as well as at least the parts of the hinges intended to come into contact with said glasses, are overmolded with a material identical to that of which said glasses are made, the joining of said parts overmolded to said glasses being carried out by an adhesive joint suitable for bonding said material.
Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé la figure unique représente une vue partielle schématique en perspective d'une paire de lunettes réalisée selon le procédé conforme à l'invention. In the accompanying drawing, the single figure represents a partial schematic perspective view of a pair of glasses produced according to the method according to the invention.
Sur cette figure on peut voir qu'une paire de lunettes réalisée selon le procédé objet de la présente invention comporte deux verres 1 reliés par un pont 2, ainsi que deux branches 3 montées chacune sur une charnière 4 solidarisée à un verre 1. In this figure, it can be seen that a pair of glasses produced according to the process which is the subject of the present invention comprises two glasses 1 connected by a bridge 2, as well as two branches 3 each mounted on a hinge 4 secured to a glass 1.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
Le pont 2 se présente sous la forme d'une barre métallique 20 cintrée pour approximativement épouser l'arête du nez, dont les extrémités 21 sont prolongées chacune vers le bas par une extension 22 munie d'une ailette 23 de manière à constituer un pince-nez. The bridge 2 is in the form of a metal bar 20 bent to approximate the bridge of the nose, the ends 21 of which are each extended downwards by an extension 22 provided with a fin 23 so as to constitute a clamp -nose.
On notera que la présence d'un pince-nez n'est pas obligatoire, il permet toutefois de stabiliser la paire de lunettes. It will be noted that the presence of a nose clip is not compulsory, it nevertheless makes it possible to stabilize the pair of glasses.
Les extrémités 21 de la barre métallique 20 sont surmoulées chacune d'un plot 24 réalisé dans un matériau identique à celui dont sont faits les verres 1. The ends 21 of the metal bar 20 are each overmolded with a stud 24 made of a material identical to that of which the glasses 1 are made.
La solidarisation du pont 2 aux verres 1 est obtenue par collage des plots 24 sur la tranche 10 des verres 1 au moyen d'un joint 5 d'une colle adaptée au collage du matériau dont sont faits les verres 1 et les plots 24. The connection of the bridge 2 to the glasses 1 is obtained by bonding the studs 24 to the edge 10 of the glasses 1 by means of a seal 5 of an adhesive suitable for bonding the material from which the glasses 1 and the studs 24 are made.
On notera que de préférence les plots 24 sont surmoulés sur des parties de la barre métallique 20 dont les formes assurent la stabilité des plots 24, en vue de procurer une parfaite rigidité de la liaison des deux verres 1. It will be noted that preferably the studs 24 are overmolded on parts of the metal bar 20 whose shapes ensure the stability of the studs 24, with a view to providing perfect rigidity in the connection of the two glasses 1.
On notera également qu'il est parfaitement possible de surmouler complètement la barre métallique 20 et de donner ainsi au pont 2 une forme originale. It will also be noted that it is perfectly possible to completely overmold the metal bar 20 and thus give the bridge 2 an original shape.
Les charnières 4 sont solidarisées aux verres 1 de la même manière, c'est-à-dire qu'elles sont enveloppées par surmoulage d'un matériau identique à celui dont sont faits les verres 1 et les plots 24, ce qui permet leur solidarisation sur la tranche 10 des verres 1 du côté extérieur de ceux-ci au moyen d'un joint 6 de la même colle. The hinges 4 are secured to the glasses 1 in the same way, that is to say that they are enveloped by overmolding of a material identical to that of which the glasses 1 and the pads 24 are made, which allows them to be secured on the edge 10 of the glasses 1 on the outside of these by means of a seal 6 of the same glue.
On notera que les charnières 4 peuvent ne pas être totalement enveloppées par surmoulage, dans ce cas, seule leur partie destinée à venir au contact d'un verre 1 est surmoulée, cette partie étant bien entendue de forme apte à retenir le matériau de surmoulage. It will be noted that the hinges 4 may not be completely wrapped by overmolding, in this case, only their part intended to come into contact with a glass 1 is overmolded, this part being clearly understood in a shape capable of retaining the overmolding material.
On notera également qu'il est possible de solidariser le pont 2 et les charnières 4 autrement que sur la tranche 10 des verres 1, sur la face intérieure de ceux-ci et en bordure par exemple, avec toutefois l'inconvénient de restreindre le champ de vision. It will also be noted that it is possible to secure the bridge 2 and the hinges 4 other than on the edge 10 of the glasses 1, on the inner face of these and at the edge for example, with the disadvantage of narrowing the field. of vision.

outre les avantages précités de solidité et de fiabilité des collages, le procédé d'assemblage des verres sur une monture de lunettes selon l'invention permet de faire varier la couleur de la monture en utilisant des matériaux de surmoulage de couleurs différentes. in addition to the aforementioned advantages of solidity and reliability of the collages, the method of assembling the lenses on a spectacle frame according to the invention makes it possible to vary the color of the frame by using molding materials of different colors.
