Abstract

La présente invention concerne un store déroulant à sécurité améliorée. Ledit store déroulant comprend : un cadre présentant une longueur prédéterminée dans le sens horizontal ; une tige d'enroulement qui est supportée en rotation par le cadre et qui présente une longueur prédéterminée dans le sens horizontal ; un élément tamisant dont une extrémité supérieure est fixée à la tige d'enroulement ; un premier engrenage conique comprenant un arbre de commande qui est accouplé à une extrémité de la tige d'enroulement ; un second engrenage conique comprenant un arbre de commande qui est mis en prise dans le sens perpendiculaire avec l'arbre de commande du premier engrenage conique ; et une poignée de réglage dont une extrémité est accouplée à l'arbre de commande du second engrenage conique et qui présente une longueur prédéterminée dans le sens vertical. Ledit élément tamisant est déplacé vers le haut/vers le bas par la rotation de la tige d'enroulement elle-même induite par la rotation de la poignée de réglage. Nothing to be translated
