Abstract
A rolling shutter characterized by an array of edge-adjacent, parallel shutter slats and full shutter width, clear shutter segments or links articulately interconnecting respective pairs of adjacent shutter slats. The links are telescopically movable in the slats to permit relative movement of the slats between spaced-apart and juxtaposed positions. When spaced apart, the slats form therebetween a gap which exposes the clear link which permits passage of light over substantially the full extent of the gap. The clear links also provide a double hinge-like joint between adjacent slats. The shutter slats are also uniquely reinforced and have an improved exterior appearance.
