ABSTRACT:
A roller shutter includes a plurality of horizontal slats (I) each provided with a flat lug (22) projecting from each end and mounting inside guide rails (V) on both sides of the window or door. Each slat has its upper edge (3) bent in a hook-profile in one direction and its lower edge (4) bent in a hook-profile in the opposite direction. The upper edge of each slat engages the lower edge of the adjoining slat in such a manner that all slats of the shutter are in firm engagement wile their axes are at a possible maximum distance from each other, but are releasable from each other by their rotation about their axes whenever the shutter is lowered with the lowermost slat resting on the window sill with the slat axes at a minimum distance from each other. Rotation of the slats is carried out by slotted rotors (III) rotatably mounted in the guide rails (V) whereof each rotor slot engages one flat lug (22), at minimum distance. All rotors on either side are simultaneously rotated about a desired angle by lever means (33), thereby disengaging the respective slat edges and holding the slats in angular position.
