Abstract

L'invention fournit une vitrine qui donne l'effet qu'une image sort directement d'une paroi, et qui est susceptible d'augmenter la capacité d'attirer la clientèle.　La vitrine de l'invention est constituée d'une vitre sur une face paroi, et d'un dispositif d'affichage d'image aérienne agencé côté interne de la vitre, lequel dispositif d'affichage d'image aérienne projette une image aérienne côté externe de la vitre. Ce dispositif d'affichage d'image aérienne est à son tour constitué d'un corps destiné à la projection formant la source de l'image aérienne, et d'une plaque optique type à transmission récursive s'intercalant selon un angle constant entre le corps destiné à la projection et la vitre. L'image aérienne peut être projetée à travers une plaque transparente incorporée à la vitre. Selon un mode de réalisation, une feuille sombre restreignant au maximum la réflexion et la diffusion de la lumière, est agencée dans un espace côté interne de la vitre où est agencé le dispositif d'affichage d'image aérienne.
