Abstract

The projection device projects the route, reproduced as a negative image on transparent paper, onto the interior of the vehicle windscreen glass (6). The route, or map, is supported (1) on a slim, inclined, hinged (13) frame, on a frosted glass (2). The inclination is adjusted by screws (8) and a surrounding cardboard, or fabric, bellows masks light from around the frame, from the projector lamp (7).The hinged frame may be mounted on a dash base (15), with the hinge adjacent to the windscreen. This base may be attached to the horizontal section of the vehicle dashboard (9) edge by pads (3). The route may be on plastic film and the image reflected onto the windscreen, without hampering the drivers normal vision.

Description

-1- L'invention concerne un dispositif de projection d'un plan de guidage-1- The invention relates to a device for projecting a guide plane

routier constitué d'un support inclinable  road consisting of a tilting support

portant sur sa partie supérieure une plaque de verre dépoli.  carrying on its upper part a frosted glass plate.

Cette plaque reçoit l'image négative reproduite sur un _ papier plastique transparent d'un plan routier. Sous cette  This plate receives the negative image reproduced on a transparent plastic paper of a road map. Under this

plaque on a aménagé un éclairage de faible intensité.  plate we installed a low intensity lighting.

L'inclinaison réglable du support permet de projeter sur le pare-brise avant d'une voiture l'image réelle du plan routier sans altérer la visibilité. Le support de faible a épaisseur est placé devant le conducteur sur la partie  The adjustable tilt of the support makes it possible to project the real road map image on the front windshield of a car without impairing visibility. The thin support is placed in front of the conductor on the part

horizontale du tableau de bord.horizontal dashboard.

Lorsqu'un conducteur de véhicule circule soit en agglomération, soit sur la route, il est amené fréquemment à consulter un plan pour s'orienter. La gêne créee par cette 4) consultation est considérable, soit pour l'usager, soit pour  When a vehicle driver is driving in built-up areas or on the road, he is frequently called upon to consult a map for orientation. The discomfort created by this 4) consultation is considerable, either for the user or for

son environnement.its environment.

Pour atténuer et résoudre ces inconvénients certains industriels ont développé des systèmes de cartographie qui, placés sur un support optique, facilitent la conduite. Ces systèmes cartographiques, quelques soient les compléments électroniques qu'on leur ajoute, obligent toujours le conducteur à consulter à l'arrêt le plan pour s'orienter. En outre, ces systèmes ne sont applicables que pour une surface localisée très limitée. L'extension de cette cartographie ?- opto-électronique à toute une ville ou à un ensemble de localité devient rapidement onéreuse pour l'usager. Enfin, -2- les modifications routières doivent être constamment  To mitigate and resolve these drawbacks, some manufacturers have developed mapping systems which, placed on an optical support, facilitate driving. These cartographic systems, whatever electronic complements are added to them, always oblige the driver to consult the map when stopped to find his way. In addition, these systems are only applicable for a very limited localized area. The extension of this opto-electronic cartography to an entire city or to a set of localities quickly becomes expensive for the user. Finally, -2- the road modifications must be constantly

actualisées à ces systèmes.updated to these systems.

La présente invention permet de palier ces inconvénients en utilisant les plans routiers existants ou vendus couramment dans le commerce. Elle s'adapte facilement à tous les véhicules existants et présente l'avantage d'être  The present invention overcomes these drawbacks by using existing road plans or those commonly sold commercially. It easily adapts to all existing vehicles and has the advantage of being

d'un coût modique par rapport aux systèmes connus.  low cost compared to known systems.

L'invention objet du présent dépôt a pour principe d'utiliser l'image négative obtenue à partir de la reproduction sur un papier transparent d'un plan d'une localité ou d'un circuit routier. Ce plan négatif transparent, obtenu en noir et blanc ou en couleur, est  The invention which is the subject of this filing has the principle of using the negative image obtained from the reproduction on transparent paper of a plan of a locality or of a road circuit. This transparent negative plane, obtained in black and white or in color, is

projeté sur le pare-brise placé devant le conducteur.  projected on the windscreen placed in front of the driver.

L'image négative renversée devient une image réelle, qui apparaît en filigramme sur le pare-brise devant le conducteur. La finesse des traits permet au conducteur du véhicule de lire et décoder le plan en même temps qu'il conduit son véhicule. L'invention dénommée Disositif de Projection de plan de guidage routier est caractérisée dans la réalisation d'une image négative d'un plan quelconque, reproduite sur un papier ou plastique transparent. L'image négative obtenue est projetée sur le pare-brise intérieur placé devant le conducteur au moyen d'un support inclinable dont la partie supérieure est constituée d'un verre dépoli, la partie inférieure est dotée d'une lumière dont l'intensité ne gêne -3- pas le conducteur; le support de faible épaisseur se fixe sur le plan horizontal du tableau de bord au moyen de pattes d'ancrage. L'invention ainsi définie sera mieux comprise grâce aux dessins annexés qui ne sont présentés qu'à titre d'exemple  The negative image reversed becomes a real image, which appears as a watermark on the windshield in front of the driver. The fine lines allow the driver of the vehicle to read and decode the plan while driving his vehicle. The invention known as the Route Guidance Plan Projection Device is characterized in producing a negative image of any plan, reproduced on transparent paper or plastic. The negative image obtained is projected on the interior windshield placed in front of the driver by means of a tilting support, the upper part of which is made of frosted glass, the lower part is provided with a light whose intensity does not annoyance -3- not the driver; the thin support is fixed on the horizontal plane of the dashboard by means of anchoring lugs. The invention thus defined will be better understood from the appended drawings which are presented only by way of example
