Abstract
Description
La présente invention concerne le domaine des rétroviseurs, notamment d'automobiles, camions, ou autres véhicules, et a pour objet un tel rétroviseur dont le miroir est composé d'une partie plane ainsi que d'une partie courbe. The present invention relates to the field of rear-view mirrors, in particular of automobiles, trucks, or other vehicles, and relates to such a rear-view mirror whose mirror is composed of a flat part as well as a curved part.
Actuellement, les rétroviseurs connus, en particulier les rétroviseurs extérieurs présentant une surface plane, n'éliminent pas complètement l'angle mort existant, et dans le cas particulier d'un véhicule en doublant un autre roulant à une vitesse plus réduite, il existe une zone où le véhicule doublant n'est plus dans la zone de contrôle du rétroviseur et n'est pas encore dans la zone d'appréhension directe par l'oeil du conducteur. Currently, known mirrors, in particular exterior mirrors with a flat surface, do not completely eliminate the existing blind spot, and in the particular case of a vehicle by overtaking another one traveling at a slower speed, there is a zone where the overtaking vehicle is no longer in the mirror control zone and is not yet in the zone of direct apprehension by the driver's eye.
On a alors pensé à créer des rétroviseurs comportant plusieurs miroirs et qui rapportent à l'oeil du conducteur des zones dont les angles varient en fonction de l'éloignement de l'oeil par rapport au miroir. Mais les angles des zones visibles par un tel rétroviseur ne sont pas égaux et un angle mort se présente malgré tout entre ces deux zones. Certains constructeurs ont alors songé à fixer les rétroviseurs extérieurs très en arrière par rapport au conducteur, pratiquement à sa hauteur, le contraignant ainsi à tourner la tête vers la gauche afin de regarder dans le rétroviseur extérieur, ce qui l'oblige, dans le même temps, à jeter un coup d'oeil directement sur la zone de l'angle mort. Mais cette démarche n'est pas automatique, peu naturelle et peu pratique. En outre, elle présente l'inconvénient de détourner le regard du conducteur du trafic à l'avant du véhicule. We then thought of creating mirrors with several mirrors and which relate to the driver's eye areas whose angles vary depending on the distance of the eye from the mirror. However, the angles of the zones visible by such a rearview mirror are not equal and a dead angle nevertheless occurs between these two zones. Some manufacturers have then thought of fixing the exterior mirrors far behind the driver, practically at his height, thus forcing him to turn his head to the left in order to look in the exterior mirror, which obliges him, in the same time, to take a look directly at the blind spot area. But this approach is not automatic, unnatural and impractical. Furthermore, it has the drawback of diverting the driver's gaze from the traffic at the front of the vehicle.
La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet un rétroviseur comprenant sur sa face avant un miroir en une seule pièce, un encadrement, ainsi qu'un pied de fixation, caractérisé en ce que le miroir est composé d'une partie plane prolongée, le long de l'un de ses côtés latéraux, par une partie courbe, dont le rayon de courbure est tel qu'il supprime totalement l'angle mort. It has, in fact, for object a rearview mirror comprising on its front face a mirror in one piece, a frame, as well as a fixing foot, characterized in that the mirror is composed of an extended flat part, along on one of its lateral sides, by a curved part, the radius of curvature of which is such that it completely eliminates the blind spot.
L'invention sera mieux comprise grâce à la des cription ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif , et expliqué avec référence aux dessins schématiques annexés, dans lesquels
la figure 1 est une vue en coupe du rétroviseur conforme à l'invention, et
la figure 2 est une vue en coupe d'une variante du rétroviseur conforme à l'invention.The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which
FIG. 1 is a sectional view of the mirror according to the invention, and
Figure 2 is a sectional view of a variant of the mirror according to the invention.
Conformément à l'invention, le miroir 1 est composé d'une partie plane 2 prolongée, le long de l'un de ses côtés latéraux, par une partie courbe 3, dont le rayon de courbure R est tel qu'il supprime totalement l'angle mort. According to the invention, the mirror 1 is composed of a flat part 2 extended, along one of its lateral sides, by a curved part 3, whose radius of curvature R is such that it completely eliminates the 'blind spot.
Ce mode de réalisation sera principalement adapté aux rétroviseurs extérieurs de véhicules automobiles. Le rétroviseur sera, bien entendu, fixé de telle manière que le côté latéral le long duquel se trouve la partie courbe 3 soit celui le plus éloigné du véhicule et que la partie courbe 3 soit dirigée en direction de l'avant du véhicule. De cette manière, l'angle mort est totalement supprimé. En effet, si le véhicule doublant est déjà bien engagé et se trouve pratiquement à la hauteur du véhicule doublé, le conducteur de ce dernier verra le véhicule doublant dans la partie courbe3 du miroir 1 du rétroviseur extérieur. Puis, lorsque le véhicule doublant sortira du champ de la partie courbe 3 du miroir 1 du rétroviseur extérieur, il sera largement dans le champ de vision du conducteur.Dans tous les cas donc, le conducteur du véhicule doublé verra le véhicule doublant, d'abord dans la partie plane 2 du rétroviseur, puis dans la partie courbe 3 de ce dernier, puis à l'oeil nu. I1 est à noter qu'à un certain moment, le conducteur peut voir le véhicule doublant à l'oeil nu ainsi que, simultanément, dans la partie courbe 3 du rétroviseur. L'angle mort a donc totalement disparu. This embodiment will be mainly adapted to exterior mirrors of motor vehicles. The rear-view mirror will, of course, be fixed in such a way that the lateral side along which the curved part 3 is located is that furthest from the vehicle and that the curved part 3 is directed towards the front of the vehicle. In this way, the blind spot is completely eliminated. Indeed, if the doubling vehicle is already well engaged and is practically at the height of the doubled vehicle, the driver of the latter will see the doubling vehicle in the curved part 3 of the mirror 1 of the exterior mirror. Then, when the overtaking vehicle leaves the field of the curved part 3 of the mirror 1 of the exterior mirror, it will be largely in the driver's field of vision. In all cases therefore, the driver of the overtaking vehicle will see the overtaking vehicle, first in the flat part 2 of the mirror, then in the curved part 3 of the latter, then with the naked eye. It should be noted that at a certain moment, the driver can see the vehicle doubling with the naked eye as well as, simultaneously, in the curved part 3 of the mirror. The blind spot has therefore completely disappeared.
Selon une variante de l'invention, le miroirlest, en outre, prolongé, le long de l'autre côté latéral, par une seconde partie courbe 4. According to a variant of the invention, the mirror ballast, in addition, extended, along the other lateral side, by a second curved part 4.
Ce type de réalisation convient particulièrement bien au rétroviseur intérieur. En effet, le miroir 1 du rétroviseur sera composé d'une partie plane 2 prolongée de part et d'autre, le long de chacun de ses côtés latéraux, par une partie courbe 3, 4. De ce fait, le conducteur aura en quelque sorte une vision panoramique lui permettant de pallier, le cas échéant, l'absence de rétroviseur extérieur ou une utilisation impossible de ce dernier, par exemple par conditions difficiles (neige, pluie, buée, rosée, etc...). This type of embodiment is particularly suitable for the interior mirror. Indeed, the mirror 1 of the rear-view mirror will be composed of a flat part 2 extended on either side, along each of its lateral sides, by a curved part 3, 4. As a result, the driver will have in some way so a panoramic view allowing it to compensate, if necessary, the absence of an exterior mirror or an impossible use of the latter, for example in difficult conditions (snow, rain, fog, dew, etc.).
Selon une caractéristique de l'invention, le rayon de courbure R est compris entre 0,5 et 0,6 fois la largeur de la surface plane du miroir, de préférence 0,54 fois cette largeur. According to a characteristic of the invention, the radius of curvature R is between 0.5 and 0.6 times the width of the plane surface of the mirror, preferably 0.54 times this width.
Selon une autre caractéristique de l'invention, le rétroviseur est en polycarbonate cintré à froid, translucide et incassable, tel que celui connu sous la dénomination commerciale Lexan, de la Société Générale Electric Plastics
France. Ainsi la fabrication dudit rétroviseur sera facile et peu coûteuse en grande série. La face arrière sera métallisée suivant les méthodes classiques, à l'aide d'un outillage adapté à la courbure de la surface.According to another characteristic of the invention, the rear-view mirror is made of cold-bent, translucent and unbreakable polycarbonate, such as that known under the trade name Lexan, from Société Générale Electric Plastics
France. Thus the manufacture of said mirror will be easy and inexpensive in large series. The rear face will be metallized according to conventional methods, using tools adapted to the curvature of the surface.
Toutes les particularités existant sur les rétroviseurs actuels pourront, bien entendu, être adaptées, à savoir rotule, système d'orientation du pied ou du miroir de l'intérieur ou de l'extérieur du véhicule, rallonge du pied pour les véhicules tractants, etc... All the features existing on current mirrors can, of course, be adapted, namely ball joint, foot or mirror orientation system inside or outside the vehicle, foot extension for towing vehicles, etc. ...
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings.
Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
