Abstract

La présente invention porte sur un dispositif de store vénitien. Le dispositif de store vénitien selon la présente invention comporte : une feuille de store vénitien dans laquelle une pluralité de feuilles d'écran sont couplées dans une direction horizontale entre des feuilles avant et arrière ; un premier rouleau d'enroulement auquel est couplé le sommet de la feuille de store vénitien ; une première unité d'entraînement qui fait tourner le premier rouleau d'enroulement de telle sorte que la feuille de store vénitien est enroulée sur la circonférence du premier rouleau d'enroulement et déroulée à partir de celle-ci, et une seconde unité d'entraînement qui fait tourner le second rouleau d'enroulement disposé en parallèle au premier rouleau d'enroulement, de telle sorte que la feuille soit avant, soit arrière de la feuille de store vénitien se déplace par rapport à l'autre feuille de façon à ouvrir la feuille d'écran.
