ABSTRACT:
A roller shutter has louvers which are pivotal about respective axes between their opening and closing positions by movement of respective chains parallel to the axes of pivot pins upon which the louvers are journaled and which interconnect links of the chain. Screw formations between the pivot pins and the links translate the linear displacement of the links into pivotal movement of the louvers. The adjoining edges of adjacent louvers can hook together.
