Description

Ecran pour lunettes et pièces pour la fabrication d'un tel écran Screen for glasses and parts for the manufacture of such a screen
La présente invention est relative à des écrans amovibles pour lunettes, à des pièces en forme de crochet pour la fixation d'un écran à des lunettes, et à une pièce d'assemblage de verres pour former un écran binoculaire amovible pour lunettes.The present invention relates to removable screens for glasses, hook-shaped parts for fixing a screen to glasses, and to a lens assembly part to form a removable binocular screen for glasses.
Le domaine technique de l'invention est celui.de la fabrication de lunettes.The technical field of the invention is that of the manufacture of glasses.
L'invention s'applique particulièrement aux dispositifs de fixation d'un verre ou écran, monoculaire ou binoculaire, à une paire de lunettes, qui comportent une goupille ou broche, déformable ou élastique, qui est conçue pour s'étendre au travers d'un canal - ou orifice traversant - percé dans l'écran - ou verre - à fixer, et qui comportent en outre une patte de fixation apte à chevaucher la tranche d'un verre ou d'une monture de lunettes.The invention is particularly applicable to devices for fixing a lens or screen, monocular or binocular, to a pair of glasses, which include a pin or pin, deformable or elastic, which is designed to extend through a channel - or through orifice - pierced in the screen - or glass - to be fixed, and which further comprise a fixing lug capable of overlapping the edge of a glass or a spectacle frame.
La demande WO 97/19384 décrit plusieurs modes de réalisation d'une telle goupille, ainsi que plusieurs modes de réalisation d'une telle patte de fixation ; ce document décrit en outre un écran binoculaire comportant une pièce cintrée et allongée, qui sert à assembler deux écrans pour former un écran binoculaire ; à chaque extrémité de cette pièce est intégrée ou fixée une patte de fixation ; dans certains modes de réalisation, la patte de fixation comporte deux languettes percées chacune d'un orifice ; les languettes et les orifices se font face.Application WO 97/19384 describes several embodiments of such a pin, as well as several embodiments of such a fixing lug; this document further describes a binocular screen comprising a curved and elongated part, which is used to assemble two screens to form a binocular screen; at each end of this part is integrated or fixed a fixing lug; in certain embodiments, the fixing lug comprises two tongues each pierced with an orifice; the tabs and the holes face each other.
La fixation de chaque patte de fixation à l'écran à l'aide d'une goupille est délicate en raison des petites dimensions de ces pièces ; cet inconvénient est grandement réduit lorsque la goupille et la patte forment une seule pièce.Attaching each bracket to the screen with a pin is tricky due to the small dimensions of these parts; this drawback is greatly reduced when the pin and the tab form a single piece.
La demande WO 98/39681 décrit un crochet pour la fixation d'un écran à des lunettes qui comporte une telle goupille ou broche et une telle patte ou arche de fixation, qui remédie à cet inconvénient.Application WO 98/39681 describes a hook for fixing a screen to glasses which includes such a pin or pin and such a fixing tab or arch, which overcomes this drawback.
La présente invention a pour objet de proposer un tel crochet qui soit encore amélioré.The object of the present invention is to provide such a hook which is further improved.
L'invention a également pour objet de proposer un écran binoculaire pour lunettes qui soit amélioré, ainsi qu'un kit spécialement conçu pour permettre la fabrication, par un opticien, à l'unité et à la demande, d'un écran monoculaire ou binoculaire de forme et dimensions adaptées à celle d'une paire de lunettes déterminée.The object of the invention is also to provide an improved binocular screen for glasses, as well as a kit specially designed to allow the manufacture, by an optician, individually and on demand, of a monocular or binocular screen of shape and dimensions adapted to that of a determined pair of glasses.
L'invention a également pour objet de remédier, en partie au moins, aux inconvénients des pièces de fixation d'écran et aux écrans supplémentaires pour lunettes, connus.The invention also aims to remedy, at least in part, the drawbacks of screen fixing parts and additional screens for glasses, known.
Selon un premier aspect de l'invention, il est proposé une attache - ou pièce de fixation - pour solidariser de façon amovible un écran percé d'orifices à des lunettes comportant des verres et une monture ; l'attache comporte une broche apte à s'étendre dans un des orifices de l'écran, et une portion - ou cavalier - solidaire de la broche et apte à chevaucher la tranche d'un des verres et/ou de la monture ; l'attache comporte en outre au moins une portion d'appui, de préférence une portion de face d'appui, en particulier une ou plusieurs face(s) d'appui, qui est (sont) apte(s) à glisser sur la tranche d'un verre de lunettes et/ou sur la monture, de façon à permettre une solidarisation de l'écran aux lunettes, par une déformation sensiblement élastique de l'attache - en particulier de ladite portion ou cavalier -, sans nécessiter de manipulation - ou action manuelle ou digitale - directe, par l'utilisateur, sur l'attache, pour provoquer cette déformation ; l'invention permet de réaliser un engagement du cavalier avec la périphérie du verre et/ou de la monture, par un déplacement et une poussée de l'écran en direction du verre de lunettes, jusqu'à engagement du verre ou de la monture dans une rainure ou encoche de l'attache.According to a first aspect of the invention, there is provided an attachment - or fixing piece - for removably securing a screen pierced with orifices to glasses comprising glasses and a frame; the fastener comprises a pin capable of extending into one of the orifices of the screen, and a portion - or jumper - integral with the pin and able to overlap the edge of one of the lenses and / or of the frame; the fastener further comprises at least one support portion, preferably a support face portion, in particular one or more support face (s), which is (are) able (s) to slide on the edge of a spectacle lens and / or on the frame, so as to allow the screen to be secured to the spectacles, by a substantially elastic deformation of the fastener - in particular of said portion or rider -, without requiring manipulation - or manual or digital action - direct, by the user, on the fastener, to cause this deformation; the invention makes it possible to engage the rider with the periphery of the lens and / or the frame, by moving and pushing the screen in the direction of the spectacle lens, until engagement of the lens or the frame in a groove or notch in the fastener.
Un écran muni de telles attaches est plus facile à solidariser à une paire de lunettes que les attaches décrites dans WO 98/39681 ; de préférence, un écran monoculaire selon l'invention comporte trois attaches fixées à la périphérie de l'écran : deux attaches sont disposées le long du bord supérieur de l'écran de façon à pouvoir s'engager à proximité du pontet et du tenon d'une paire de lunettes, tandis qu'une troisième attache est disposée le long du bord inférieur de l'écran, de façon de préférence décentrée - du côté temporal de la paire de lunettes ; dans le cas d'un écran présentant une telle configuration, les encoches des deux attaches supérieures de l'écran peuvent être emboîtées autour de la tranche du verre ou de la monture de lunettes, l'écran étant maintenu légèrement incliné par rapport au verre ; par un mouvement ultérieur de pivotement de l'écran par rapport au verre, l'attache inférieure est amenée au contact de la partie inférieure de la tranche du verre de lunette, par sa face d'appui glissant ; la poursuite de ce mouvement provoque le franchissement de la tranche du verre par la face d'appui glissant, grâce à la déformation de l'attache inférieure, jusqu'à engagement de la tranche du verre dans la rainure ou encoche de l'attache inférieure (voir figures 5 à 7 en particulier).A screen provided with such attachments is easier to attach to a pair of glasses than the attachments described in WO 98/39681; preferably, a monocular screen according to the invention comprises three fasteners fixed to the periphery of the screen: two fasteners are arranged along the upper edge of the screen so as to be able to engage near the trigger guard and the tenon d 'a pair of glasses, while a third fastener is arranged along the lower edge of the screen, preferably off-center - on the temporal side of the pair of glasses; in the case of a screen having such a configuration, the notches of the two upper fasteners of the screen can be fitted around the edge of the glass or of the spectacle frame, the screen being kept slightly inclined relative to the glass; by a subsequent pivoting movement of the screen relative to the glass, the lower clip is brought into contact with the lower part of the edge of the spectacle lens, by its sliding bearing face; the continuation of this movement provokes the crossing of the edge of the glass by the sliding bearing face, thanks to the deformation of the lower fastener, until engagement of the edge of the glass in the groove or notch of the lower fastener (see figures 5 to 7 in particular).
La configuration des attaches selon l'invention permet également de solidariser un écran à un verre en présentant l'écran en regard du verre, en disposant les faces d'appui glissant respectives des trois attaches, au contact de trois zones de la tranche du verre ou de la monture de lunettes, puis en poussant l'écran contre le verre selon un mouvement de translation, jusqu'à engagement des trois encoches sur la tranche du verre ou de la monture ; ces opérations peuvent ainsi être effectuées d'une seule main par le porteur des lunettes.The configuration of the fasteners according to the invention also makes it possible to secure a screen to a glass by presenting the screen facing the glass, by arranging the respective sliding bearing faces of the three fasteners, in contact with three zones of the edge of the glass. or of the spectacle frame, then pushing the screen against the lens in a translational movement, until engagement of the three notches on the edge of the lens or of the frame; these operations can thus be carried out with one hand by the wearer of the glasses.
Ladite face ou portion de face d'appui glissant peut être gauche ; selon un mode préféré de réalisation, elle est cependant sensiblement plane.Said face or portion of sliding bearing face may be left; according to a preferred embodiment, it is however substantially planar.
Afin de faciliter le glissement de I 'attache contre le verre ou la monture de lunettes, cette face ou portion de face d'appui glissant est de préférence inclinée, par rapport à l'axe longitudinal de la broche, d'un angle situé dans une plage allant de 15 à 75 degrés, de préférence de l'ordre de 30 à 60 degrés, en particulier voisin de 40 à 50 degrés. Lorsque la face d'appui est gauche, cet angle peut bien entendu varier d'une partie à l'autre de cette face.In order to facilitate the sliding of the fastener against the lens or the spectacle frame, this face or portion of sliding sliding face is preferably inclined, relative to the longitudinal axis of the spindle, by an angle situated in a range from 15 to 75 degrees, preferably of the order of 30 to 60 degrees, in particular close to 40 to 50 degrees. When the bearing face is left, this angle can of course vary from one part to another of this face.
