La presente invention a pour objet un dispositif de lunettes. The present invention relates to a spectacle device.

De maniere traditionnelle, les verres d'une padre de lunettes vent montes enchasses dans une monture qui peut etre realisee en Traditionally, the glasses of a padre of glasses are mounted in a frame that can be made in

metal ou en matiere plastique ou analogue. metal or plastic or the like.

Dans un but initialement de gain de poids et d'economie, puis plus tard d'esthetique, il a ete propose de reduire les dimensions de la monture. Dans un premier temps les cerclages dans lesquels vent enchasses les verres ont ete supprimes totalement ou en partie, en sorte que les branches et le pontet soient solidarises directement aux verres. La fixation aux verres du pontet et des branches, ou plus exactement des pivots de ces derrieres, est realisee au moyen de vis, vissees apres percage, soit dans la tranche, soit dans l'une ou l'autre des faces desdits verres. On In an initial goal of weight gain and economy, then later aesthetic, it was proposed to reduce the dimensions of the frame. Initially the straps in which the wind encased the glasses were removed completely or in part, so that the branches and the trigger guard are secured directly to the glasses. Attachment to the glasses of the trigger guard and of the branches, or more precisely of the pivots of these backs, is carried out by means of screws, screwed after drilling, either in the edge, or in one or the other of the faces of said glasses. We

notera que certains utilisent egalement le collage. note that some also use collage.

Ces progres realises en matiere de monture ont toutefois un prix, en sorte que les lunettes qui en beneficient vent generalement reservees a une clientele relativement aisee. Dans ce cas il est difficile d'envisager la possibilite pour chacun de disposer de plusieurs padres de lunettes, de grande qualite de fabrication, These advances in frame, however, have a price, so the glasses that benefit from them are generally reserved for relatively affluent customers. In this case it is difficult to envisage the possibility for each of them to have several frames of glasses, of high quality of manufacture,

presentant des esthetiques differentes. with different aesthetics.

La presente invention a pour but de remedier a cette carence, en proposant un dispositif de lunettes autorisant la possibilite a The purpose of the present invention is to remedy this deficiency, by proposing a device for glasses allowing the possibility of

tout un chacun de disposer de plusieurs montures de lunettes. everyone has several glasses frames.

Le dispositif de lunettes selon l' invention est du type sans cerclage ou le pontet et les pivots ou analogue des branches vent fixes directement sur les verres, ou avec cerclage, et il se caracterise essentiellement en ce que d'une part ledit pontet est compose d' au moins trots pieces, deux destinees a 8tre solidarisees chacune fixement a un verre, tandis que la troisieme est apte a etre solidarisee a chacune des deux autres par l'intermediaire d'un moyen de fixation reversible; et d'autre part, chacune desdites branches comporte au moins deux pieces, une premiere piece destinee a etre solidarisee fixement au verre, et une seconde piece, liee a la branche, apte a etre solidarisee a ladite premiere piece par The spectacle device according to the invention is of the type without strapping or the trigger guard and the pivots or the like of the fixed wind arms directly on the glasses, or with strapping, and it is essentially characterized in that on the one hand said trigger guard is composed of at least three pieces, two intended to be secured each fixedly to a glass, while the third is capable of being secured to each of the other two by means of a reversible fixing means; and on the other hand, each of said branches comprises at least two pieces, a first piece intended to be fixedly secured to the glass, and a second piece, connected to the branch, capable of being secured to said first piece by

l'intermediaire d'un moyen de fixation reversible. through a reversible fastening means.

L'utilisation de moyens de fixation reversible pour la solidarisation des verres au reste de la monture, a savoir le pontet et les branches, permet d'envisager pour un utilisateur de disposer d'un jeu de plusieurs pieces differentes, et/ou de verres de formes differentes, en sorte d'autoriser la construction par ledit The use of reversible fixing means for securing the lenses to the rest of the frame, namely the trigger guard and the arms, makes it possible for a user to envisage having a set of several different pieces, and / or lenses of different forms, so as to authorize the construction by said

utilisateur de lunettes d'esthetiques differentes. user of glasses of different aesthetics.

La composition de base pourrait ainsi comprendre deux padres de lunettes comprenant chacune deux verres, deux branches et un pontet, en sorte de permettre la construction de huit padres logiques de The basic composition could thus include two padres of glasses each comprising two glasses, two branches and a trigger guard, so as to allow the construction of eight logical padres of

lunettes, et bien d'autres plus fantaisistes. glasses, and many more fanciful.

En multipliant le nombre de jeux de deux branches et un pontet, et eventuellement le nombre de verres de formes differentes, on peut creer de nombreuses de padres de lunettes differentes, avec un By multiplying the number of sets of two branches and a trigger guard, and possibly the number of glasses of different shapes, we can create many different frames of glasses, with a

relativement petit nombre de pieces. relatively small number of pieces.

L' assemblage peut etre realise par l'opticien, qui peut ainsi proposer un choix important de padres de lunettes tout en limitant ses stocks, soit par l'utilisateur lui-meme s'il a opte pour un set The assembly can be carried out by the optician, who can thus offer a large choice of glasses frames while limiting his stocks, either by the user himself if he has opted for a set.

de plusieurs pieces differentes.of several different pieces.

Selon un mode de realisation particulier du dispositif selon l' invention, le pivot de chacune des branches est solidaire de la According to a particular embodiment of the device according to the invention, the pivot of each of the branches is integral with the

piece solidaire du verre et destinee a recevoir ladite branche. piece integral with the glass and intended to receive said branch.

Selon un autre mode de realisation particulier du dispositif selon l' invention, le pivot de chacune des branches est solidaire de According to another particular embodiment of the device according to the invention, the pivot of each of the branches is integral with

des formes concordantes emboltables. concordant emboiderable shapes.

Selon un mode de realisation particulier du dispositif selon l' invention, l'une des pieces a solidariser a une autre piece comporte un element saillant en forme sensiblement de cylindre d' exe parallele au plan general d'un verre, tandis que ladite autre piece comporte une cavite de forme complementaire destinee a loger ledit element, ladite cavite etant associee a un moyen de butee apte a According to a particular embodiment of the device according to the invention, one of the pieces to be joined to another piece has a projecting element in the form of a substantially exe cylinder parallel to the general plane of a glass, while said other piece comprises a cavity of complementary shape intended to accommodate said element, said cavity being associated with a stop means capable of

limiter la profondeur d'enfoncement. limit the depth of penetration.

De maniere preferentielle, mais non indispensable, chacun des moyens de fixation reversible est associe a moyen apte a verrouiller Preferably, but not essential, each of the reversible fixing means is associated with means capable of locking

l'emboitement, qui peut consister en un moyen d'encliquetage. interlocking, which may consist of a snap-fastening means.

Selon une autre caracteristique additionnelle du dispositif selon l' invention, les pieces fixees sur les verres consistent chacune en un bloc presentant une feuillure destinee a cooperer avec According to another additional characteristic of the device according to the invention, the parts fixed to the glasses each consist of a block having a rebate intended to cooperate with

le bord du verre, ledit bloc etant fixe au moyen d'au moins une vis. the edge of the glass, said block being fixed by means of at least one screw.

Par ailleurs, de maniere avantageuse, le pontet comporte a l'arriere et vers le teas deux prolongements munis chacun en extremite d'une ailette articulee ou non, constituent un appui nasal. On notera egalement qu'il peut etre prevu d'adjoindre au dispositif selon ['invention, des elements de cerclage rapportes sur le bord des verres. Ces elements, qui peuvent etre realises dans differents materiaux, et etre de differentes couleurs et formes, vent destines a recouvrtr la partie superieure du bord des verres ou Furthermore, advantageously, the trigger guard has at the rear and towards the teas two extensions each provided at the end with a hinged or non-articulated fin, constitute a nasal support. It will also be noted that it may be provided to add to the device according to the invention, strapping elements attached to the edge of the glasses. These elements, which can be produced in different materials, and be of different colors and shapes, are intended to cover the upper part of the edge of the glasses or

la partie inferieure, ou les deux.the lower part, or both.

La fixation de ces elements est realisee de preference par leurs extremites, sur les pieces solidaires des verres, et/ou sur le The fixing of these elements is preferably carried out by their ends, on the integral parts of the glasses, and / or on the

pontet et les branches.trigger guard and branches.

En reference a la figure l, on peut voir un dispositif de lunettes selon ['invention. Il comporte de maniere traditionnelle deux verres relies entre eux par un pontet 2, et deux branches 3 With reference to FIG. 1, one can see a spectacle device according to the invention. It comprises in a traditional manner two glasses linked together by a trigger guard 2, and two branches 3

dont on ne volt que l'extremite.of which only the end is flown.

En reference egalement a la figure 2, on peut voir que, selon l' invention, le pontet 2 comporte une piece transversale 20 raccordee a chacun des verres 1 au moyen d'une piece intermediaire 4 With reference also to FIG. 2, it can be seen that, according to the invention, the trigger guard 2 comprises a transverse piece 20 connected to each of the glasses 1 by means of an intermediate piece 4

solidarisee fixement au verre 1.fixedly secured to the glass 1.

Dans le mode de realisation represente, les pieces intermediaires 4 se presentent chacune sous la forme d'un bloc comportant une feuillure 40 destinee a cooperer etroitement avec le bord 10 du verre 1, cet assemblage etant complete du vissage de, de In the embodiment shown, the intermediate pieces 4 are each in the form of a block comprising a rebate 40 intended to cooperate closely with the edge 10 of the glass 1, this assembly being complete with the screwing of,

preference, deux vis 41 superposees, dont une seule est visible. preferably, two superimposed screws 41, only one of which is visible.

L'assmhlage de la piece transversale 20 du pontet 2 aux pieces intermediaires 4 est realise par emboltement d' elements de formes complementaires. Ainsi, de la piece transversale 20 comporte a chacune de ses extremites une paroi plane 21 de laquelle fait saillie un element 22 de forme globalement cylindrique d' exe parallele au plan general des verres 1, tandis que chacune des pieces intermediaires 4 comporte dans sa partie extreme opposee a celle solidarisee au verre 1, en arriere d'une paroi plane 42 destinee a venir au contact de la paroi 21, une cavite cylindrique 43 de forme complementaire s'ouvrant dans la paroi 42, en sorte de permettre l'emboltement serre de l' clement The assembly of the transverse piece 20 of the trigger guard 2 to the intermediate pieces 4 is carried out by embolishing elements of complementary shapes. Thus, the transverse piece 20 has at each of its ends a flat wall 21 from which protrudes an element 22 of generally cylindrical shape exe parallel to the general plane of the glasses 1, while each of the intermediate pieces 4 has in its part extreme opposite to that secured to the glass 1, behind a flat wall 42 intended to come into contact with the wall 21, a cylindrical cavity 43 of complementary shape opening in the wall 42, so as to allow the embollement tight of clement

On notera que la cavite 43 n'est pas traversante, elle comporte un fond 44 situe dans la partie superieure de l' clement 4, ce fond Note that the cavity 43 is not through, it has a bottom 44 located in the upper part of the element 4, this bottom

44 constituent l'arret d'enfoncement de l' clement 22. 44 constitute the insertion stop of the element 22.

On notera egalement que, sur la figure 1, le pontet 2 comporte inferieurement deux prolongements 23 equipes chacun en extremite It will also be noted that, in FIG. 1, the trigger guard 2 has two extensions 23, each equipped at the bottom,

d'une ailette 24, afin de constituer un appui nasal. a fin 24, in order to constitute a nasal support.

En reference maintenant a la figure 3, on peut voir que, selon l' invention, chacune des branches 3 est raccordee a un verre 1 au Referring now to FIG. 3, it can be seen that, according to the invention, each of the branches 3 is connected to a glass 1 at the

moyen d'une piece intermediaire 5 solidarisee fixement a ce dernier. by means of an intermediate piece 5 fixedly attached to the latter.

Dans le mode de realisation represente, tout comme pour les pieces intermediaires 4, la piece intermediaire 5 se presente sous la forme d'un bloc comportant une feuillure 50 destinee a cooperer etroitement avec le bord 10 du verre 1, cet assemblage etant complete du vissage de, de preference, deux vis 51 superposees, dont In the embodiment shown, as for the intermediate pieces 4, the intermediate piece 5 is in the form of a block comprising a rebate 50 intended to cooperate closely with the edge 10 of the glass 1, this assembly being complete with the screwing of, preferably, two superimposed screws 51, of which

une senle est visible.a track is visible.

s 2841001 Comme pour les pieces 4, l' assemblage d'une branche 3 a une piece intermediaire 5 est realise par emboltement d' elements de s 2841001 As for parts 4, the assembly of a branch 3 to an intermediate part 5 is carried out by embossing of elements of

formes complementaires.complementary forms.

Ainsi, la piece intermediaire 5 comporte a son extremite une S paroi plane 52 de laquelle fait saillie un element 53 de forme globalement cylindrique d' exe parallele au plan generale des verres 1, tandis que la branche 3 comporte, dans sa partie extreme de raccordement, un bloc 30 abritant une charniere ou analogue 31 et presentant lateralement, en arriere d'une paroi plane 32 destinee a venir au contact de la paroi 52, une cavite cylindrique 33 de forme complementaire s'ouvrant dans la paroi 32, en sorte de permettre l'emboltement serre de l' clement 53 dans la cavite 33. La cavite 33 n'est pas traversante, elle comporte un fond 34 qui constitue Thus, the intermediate piece 5 comprises at its end a flat wall S 52 from which protrudes an element 53 of generally cylindrical shape exe parallel to the general plane of the glasses 1, while the branch 3 comprises, in its extreme connection part , a block 30 housing a hinge or the like 31 and having laterally, behind a flat wall 32 intended to come into contact with the wall 52, a cylindrical cavity 33 of complementary shape opening in the wall 32, so as to allow the tight fit of the element 53 in the cavity 33. The cavity 33 is not through, it has a bottom 34 which constitutes

l'arret d'enfoncement de l' clement 53. the insertion stop of the element 53.

On notera que dans le mode de realisation represente la charniere 31 est solidaire fixement de la branche 3, elle pourrait It will be noted that in the embodiment represented the hinge 31 is fixedly secured to the branch 3, it could

toutefois etre solidaire fixement de la piece intermediaire 5. however be fixedly attached to the intermediate piece 5.

On notera que la forme cylindrique des elements 22 et 53, et des cavites 43 et 33, peut 8tre remplacee par d'autres, tronconique en sorte de realiser un assemblage de type cone Morse, ou en queue It will be noted that the cylindrical shape of the elements 22 and 53, and of the cavities 43 and 33, can be replaced by others, frustoconical so as to produce an assembly of the Morse cone type, or in a tail

d'aronde par exemple.dovetail for example.

La piece transversale 20 du pontet 2 prend appui sur le nez par l'intermediaire des ailettes 24 et des prolongements 23, tandis que les verres 1 prennent appui sur le pontet par l'intermediaire des 2 fonds 44 des cavites 43, et que les branches 3 vent en appui, par l'intermediaire des fonds 34 des cavites 33, sur les verres 1. La fixation par emboltement peut done etre suffisante dans la mesure ou les usinages vent precis. Il peut toutefois etre necessaire de completer l'emboltement par un verrouillage, loquel peut consister en un simple encliquetage de reliefs complementaires ou un indexage a billet On notera par ailleurs que les verres 1 peuvent etre de plus habilles par des elements 11 et 12, visibles sur la figure 1, destines a etre rapportes sur les bords 10, respectivement au-dessus The transverse piece 20 of the trigger guard 2 is supported on the nose by the intermediary of the fins 24 and extensions 23, while the glasses 1 are supported on the trigger guard by the intermediary of the 2 bottoms 44 of the cavities 43, and that the branches 3 wind in support, through the funds 34 of the cavities 33, on the glasses 1. The embedding may therefore be sufficient insofar as the precise wind machining. It may however be necessary to complete the embolism by a locking, loquel can consist of a simple snap-on of complementary reliefs or a ticket indexing It will also be noted that the glasses 1 can be further dressed by elements 11 and 12, visible in Figure 1, intended to be reported on the edges 10, respectively above
