Abstract

The rectangular flexible roller blind or screen is rapidly rolled about a winding roller (100) while guided by a roller (200). Its free end is hidden and locked by a retention box (500). The free end of the blind is T-shaped and slides in U-shaped guides (600) which have small leaf springs (700) acting as brakes to the blind. One wing of the T-shaped blind end carries a spring mounted chamfered bolt which pulls through a rocker at the bottom of the retention box but slides back easily when the blind is rolled up.
