Abstract
Blind, characterized essentially by comprising a frame provided with a conventional slat system whose sides have, at points close to the vertices, two pairs of rollers movable in two guides carrying respective vertical portions fixed on the jambs of the corresponding frame, whose guides are upperly arcuately angled and extend in respective horizontal sections, being attached to a lower point of the frame of the blind a flexible and inextensible brace mounted on two upper guide pulleys and joined at the opposite end to a tensioner linked to an endless chain which meshes with a lower pinion driven by a handlebar and tensioned by an upper pulley whose chain joins another lower point of the frame of the shutter.
