Abstract

Protective goggles, particularly for parachutists, comprising a profiled transparent shell (1) equipped with a central notch (10) for the nose and with a flat peripheral rim (11). The lateral edges (12) and the lower edges (13) situated on either side of the notch (10) of the shell (1) are rectilinear, the junction (14) between the said lateral edges (12) and lower edges (13) also being rectilinear, and two tabs (2) consisting of two parts (21, 22) which are articulated with respect to each other about an axis (23) are joined via one of the two parts (21) to the lateral edges (12), while the other part (22) can pivot freely about the axis (23) and has at its end a slot (220) which is substantially parallel to the said axis (23) for the fastening of a strap.

Description

La présente invention a pour objet des lunettes de protection destinées plus particulièrement à la pratique du parachutisme. The present invention relates to protective glasses intended more particularly for the practice of parachuting.

On connaît déjà des lunettes de protection, notamment pour parachutistes, telles que celles décrites dans le document FR 2.093.398, qui sont constituées d'une coque transparente profilée comportant une échancrure pour le nez et munie sur sa périphérie d'un rebord plat revêtu d'un bourrelet d'étanchéité, une sangle fixée sur les bords latéraux de ladite coque servant à la maintenir appliquée sur le visage de l'utilisateur, ladite pouvant être placée sur ou sous le casque de ce dernier. Protective goggles are already known, in particular for paratroopers, such as those described in document FR 2,093,398, which consist of a profiled transparent shell comprising a notch for the nose and provided on its periphery with a coated flat rim a sealing bead, a strap fixed on the lateral edges of said shell serving to keep it applied to the face of the user, said being able to be placed on or under the helmet of the latter.

Toutefois ce type de lunettes n'offre pas un champ visuel suffisant, et la coque n' est pas toujours parfaitement appliquée sur le visage. However, this type of glasses does not offer a sufficient visual field, and the shell is not always perfectly applied to the face.

De plus, dans le cas où la sangle est placée sur le casque, elle ne se trouve plus dans le prolongement des rebords latéraux des lunettes, et elle exerce une traction qui tend à décoller lesdits rebords du visage de l'utilisateur. In addition, in the case where the strap is placed on the helmet, it is no longer in the extension of the side edges of the glasses, and it exerts a traction which tends to detach said edges from the face of the user.

La présente invention a pour but de remédier à ces inconvénients en proposant des lunettes plus particulièrement adaptées à la pratique du parachutisme ou de la moto, permettant d'une part d'améliorer le confort visuel de l'utilisateur et d'autre part de mieux plaquer les bords latéraux desdites lunettes sur son visage. The present invention aims to remedy these drawbacks by proposing glasses more particularly adapted to the practice of parachuting or motorcycling, allowing on the one hand to improve the visual comfort of the user and on the other hand better press the side edges of said glasses on his face.

Les lunettes de protection selon l'invention comprennent une coque transparente profilée munie d'un rebord plat recouvert d'un bourrelet d'étanchéité et elles se caractérisent essentiellement en ce que les bords latéraux destinés à venir au contact des tempes et les bords inférieurs situés de chaque coté de l'échancrure du nez et destinés à venir au contact des joues sont rectilignes, la jonction entre un bord latéral et un bord inférieur se faisant également de façon rectiligne. The protective glasses according to the invention comprise a profiled transparent shell provided with a flat rim covered with a sealing bead and they are essentially characterized in that the lateral edges intended to come into contact with the temples and the lower edges located on each side of the notch of the nose and intended to come into contact with the cheeks are rectilinear, the junction between a lateral edge and a lower edge also being made in a rectilinear manner.

Conformément à l'invention les lunettes comportent deux pattes constituées chacune de deux parties plates articulées entre elles autour d'un axe, une des deux parties étant solidarisée, par des moyens appropriés, au rebord plat extérieur à la coque, à proximité immédiate d'un bord latéral rectiligne, tandis que l'autre partie, qui peut pivoter librement autour dudit axe, comporte à son extrémité une fente sensiblement parallèle audit axe de rotation permettant la fixation d'une sangle. According to the invention, the glasses have two tabs each consisting of two flat parts hinged together around an axis, one of the two parts being secured, by appropriate means, to the flat rim outside the hull, in the immediate vicinity of a rectilinear side edge, while the other part, which can pivot freely around said axis, has at its end a slot substantially parallel to said axis of rotation allowing the attachment of a strap.

De ce fait, lorsque la sangle vient en appui sur le casque de l'utilisateur les parties mobiles des pattes de fixation se positionnent dans le prolongement de ladite sangle, tangentiellement audit casque, empêchant les extrémités de la sangle d'exercer une traction qui décollerait les rebords latéraux de la coque des tempes de l'utilisateur. Therefore, when the strap bears on the user's helmet, the moving parts of the fixing lugs are positioned in the extension of said strap, tangentially to said helmet, preventing the ends of the strap from exerting traction which would take off. the side edges of the user's temple shell.

Les avantages et les caractéristiques de la présente 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 present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé

In the attached drawing
- Figure 1 shows a partial perspective view of protective glasses according to the invention.

- la figure 2a représente une vue de dessus schématique des mêmes lunettes placées sur le visage d'un utilisateur portant un casque. - Figure 2a shows a schematic top view of the same glasses placed on the face of a user wearing a helmet.

- la figure 2b représente une vue de dessus schématique de lunettes de type connu placées sur le visage d'un utilisateur portant également un casque. - Figure 2b shows a schematic top view of known type of glasses placed on the face of a user also wearing a helmet.

Sur la figure 1 on peut voir que des lunettes selon l'invention comportent une coque 1 profilée transparente, comprenant une échancrure centrale 10 pour le nez, et entourée d'un bord périphérique plat 11 destiné à être garni d'un bourrelet d'étanchéité, non représenté. In Figure 1 we can see that glasses according to the invention have a transparent profiled shell 1, comprising a central notch 10 for the nose, and surrounded by a flat peripheral edge 11 intended to be lined with a sealing bead , not shown.

La coque 1 peut être réalisée par exemple en polycarbonate "LEXAN" permettant d'une part d'obtenir un taux de déformation visuelle quasi nul, d'autre part de limiter l'épaisseur de la coque à 1,5 mm contribuant à la non déformation visuelle et d'autre part encore de bénéficier d'un effet anti-buée intérieur et d'un effet anti-abrasif extérieur. The shell 1 can be made, for example, of "LEXAN" polycarbonate making it possible on the one hand to obtain an almost zero rate of visual deformation, on the other hand to limit the thickness of the shell to 1.5 mm contributing to the non visual deformation and on the other hand to benefit from an internal anti-fog effect and an external anti-abrasive effect.

Les bords latéraux 12 de la coque 1, dont un seul est parfaitement visible sur la figure, sont rectilignes, sensiblement verticaux, et de la même façon les bords inférieurs 13 de la coque, dont également un seul est parfaitement visible, sont également rectilignes, les bords latéraux 12 et les bords inférieurs 13 étant reliés par un bord de liaison incliné 14 également rectiligne. The lateral edges 12 of the shell 1, only one of which is perfectly visible in the figure, are rectilinear, substantially vertical, and in the same way the lower edges 13 of the shell, of which also only one is perfectly visible, are also rectilinear, the side edges 12 and the bottom edges 13 being connected by an inclined connecting edge 14 also straight.

Les bords latéraux 12 sont destinés à se plaquer sur les tempes, et les bords inférieurs 13 et de liaison 14 à être plaqués sur les joues de l'utilisateur. The lateral edges 12 are intended to be pressed against the temples, and the lower edges 13 and connecting 14 are to be pressed against the cheeks of the user.

On peut voir également que sur les bords latéraux 12 sont fixés des pattes 2, dont une seule est visible sur la figure, destinées à l'accrochage d'une sangle 3, visible sur la figure 2a. It can also be seen that on the lateral edges 12 are fixed tabs 2, only one of which is visible in the figure, intended for the attachment of a strap 3, visible in FIG. 2a.

Une patte 2 comprend deux parties planes 21 et 22 articulées entre elles autour d'un axe 23. A tab 2 comprises two flat parts 21 and 22 hinged together around an axis 23.

La partie 21 est solidarisée au bord latéral 12, par exemple au moyen de vis non représentées, l'autre partie 22 étant mobile autour de l'axe 23 sur environ 180 , limitée en rotation par son contact avec la coque 1 et la partie fixe 21. Part 21 is secured to the lateral edge 12, for example by means of screws not shown, the other part 22 being movable about the axis 23 of about 180, limited in rotation by its contact with the shell 1 and the fixed part 21.

Une sangle 3 est solidarisée à l'extrémité de la partie 22 de la patte 2, par passage dans une fente 220. A strap 3 is secured to the end of the part 22 of the tab 2, by passing through a slot 220.

La coque 1 d'autre part est percée de plusieurs petits orifices 15 disposés parallèlement aux bords latéraux 12, et permettant la régulation de la pression. The shell 1 on the other hand is pierced with several small orifices 15 arranged parallel to the lateral edges 12, and allowing the regulation of the pressure.

Si on se réfère maintenant à la figure 2a on peut voir que la sangle 3 est appliquée sur le pourtour d'un casque 4 et est fixée par ses deux extrémités 31 et 32 aux parties mobiles 22 des pattes 2, la sangle 3 se trouvant alors parfaitement dans le prolongement des parties mobiles 22 des pattes 2, en sorte que les bords latéraux 12 restent parfaitement appliqués sur les tempes de l'utilisateur. If we now refer to Figure 2a we can see that the strap 3 is applied to the periphery of a helmet 4 and is fixed by its two ends 31 and 32 to the movable parts 22 of the legs 2, the strap 3 then being perfectly in the extension of the movable parts 22 of the legs 2, so that the lateral edges 12 remain perfectly applied to the temples of the user.

Sur la figure 2b on peut voir un dispositif de lunettes de type connu sans pattes 2, dans lesquelles les extrémités 31 et 32 de la sangle 3 exercent une traction dans le sens de la flèche F sur les bords latéraux 12, cette traction tendant à écarter les bords latéraux 12 des tempes de l'utilisateur.  In Figure 2b we can see a known type of glasses device without tabs 2, in which the ends 31 and 32 of the strap 3 exert a traction in the direction of the arrow F on the lateral edges 12, this traction tending to spread the lateral edges 12 of the user's temples.
