Abstract
Abstract A shutter arrangement with profiled plastic strips which have, on their adjacent sides, interlocking complementary elements with adjacent profile strips that are mounted pivotably relative to one another on armored chain links. The profile strips are made of a transparent plastics and have, on their narrow side, at least one projection which is inserted and fastened in a complementary opening of a link of the associated armored chain. The profile strips may be made of acrylic glass or polycarbonate. All surfaces of the profile strips may be polished, and the projection of the profile strips may be substantially trapezoidal. The projections of the profile strips may be fastened in an opening of the chain links by a cross bolt. At the same time, the chain links may be made of substantially light metal, with a guide projection located on both sides of at least part of the chain links. The guide projection on both sides may be in the form of a spacer pin, projecting on both sides, and held in a cross bore of the chain links.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
119 words
A shutter arrangement comprising: profiled plastic strips having adjacent sides; interlocking means with complementary means on said adjacent side of said profiled strips; armored chain links; adjacent profiled strips being mounted pivotably relative to one another on said links; said profiled strips being of transparent plastics with all surfaces being completely polished, and having narrow sides with at least one projection; said links having opening means complementary to said projection; said projection being insertable and fastenable in said complementary opening means, said transparent plastics with all surfaces completely polished preventing undesired reflections and refractions of incident light for providing substantially uniform optically homogeneous viewing free of disturbances, said interlocking means with complementary means inhibiting formation of undesired light gaps
Claim 2
Dependent Claim
119 words
A shutter arrangement comprising: profiled plastic strips having adjacent sides; interlocking means with complementary means on said adjacent side of said profiled strips; armored chain links; adjacent profiled strips being mounted pivotably relative to one another on said links; said profiled strips being of transparent plastics with all surfaces being completely polished, and having narrow sides with at least one projection; said links having opening means complementary to said projection; said projection being insertable and fastenable in said complementary opening means, said transparent plastics with all surfaces completely polished preventing undesired reflections and refractions of incident light for providing substantially uniform optically homogeneous viewing free of disturbances, said interlocking means with complementary means inhibiting formation of undesired light gaps
