(57) This invention relates to a roller shutter with slats that open so that air and light
can pass through them even when said shutter is fully lowered.
Said shutter, suitable for windows and French windows, is of the type comprising a
plurality of slats jointed together in such a way that said shutter can be wound onto
a roller (7) so that it can be raised and lowered, said slats being designed to be
inserted into a pair of U-shaped guides (5), installed along the jambs of said windows,
characterised in that it includes one or more opening slats (2), which said slats
(2) comprise a central part (2a) and two ends (2b), said central part (2a) being articulated
in relation to said two ends (2b) and said two ends (2b) remaining inserted in said
U-shaped guides, said slats (2) being opened by means of rotation of said central
part (2a) in relation to said two ends (2b), first means being fitted for each slat
(2) which articulate said central part (2a) in relation to said ends (2b) of said
opening slat (2), and second means being fitted to cause said rotation between said
central part (2a) and said two ends (2b) of said opening slat (2).
