ABSTRACT:
The shutter is composed of a number of slats kept in parallel each other, and the slats are connected to each other with hinges so as to be folded in both forward and backward directions.
The hinges comprise the pins provided at the inside and outside corners of the butt end of one of the adjacent slats and extending in longitudinal direction of the slats, and the stoppers provided at the inside and outside corners of the butt end of the other slat and having the hinge holes which hold the said pins respectively so as to turn to the folded direction. Gaps are hardly made between adjacent slats because the turning axis of each hinge is at the inside and outside corners of each slat.
