Abstract

DISPOSITIF DE PROJECTION D’IMAGE L’invention concerne un dispositif de projection d’image (2) au sol depuis un véhicule automobile (1), comprenant une source de lumière (60), une lentille (20), un moteur (4) avec un système d’entrainement, plusieurs images (70, 71) et un ensemble de projection comprenant au moins une lentille de projection (21), caractérisé en ce que les images (70, 71) sont disposées sur une courroie (7) entrainée par au moins une roue dentée (8) actionnée par le moteur (4) et que la courroie (7) comprend des dents (72) entre lesquelles sont disposées les images (70, 71). L’utilisation d’une courroie (7) dentée permet d’avoir une surface plus longue et plus large pour placer les images et les dents (72) permettent un positionnement précis des images, et un nombre élevé d’images. Figure à publier avec l’abrégé : Figure 4IMAGE PROJECTION DEVICE The invention relates to an image projection device (2) on the ground from a motor vehicle (1), comprising a light source (60), a lens (20), a motor (4) with a drive system, several images (70, 71) and a projection assembly comprising at least one projection lens (21), characterized in that the images (70, 71) are arranged on a driven belt (7) by at least one toothed wheel (8) actuated by the motor (4) and that the belt (7) comprises teeth (72) between which the images (70, 71) are arranged. The use of a toothed belt (7) allows a longer and wider surface to place the images and the teeth (72) allow precise positioning of the images, and a high number of images. Figure to be published with the abstract: Figure 4
