ABSTRACT:
A blade member for use in a shutter curtain assembly. The blade member is of a given height and has a top, a bottom, a first edge and a second edge. A first semi-cylindrical interlocking portion extends along the first edge. The first portion includes a pair of inwardly-directed tangs which extend from opposite sides of the semi-cylinder. A second semi-cylindrical interlocking portion extends along the second edge and is sufficiently smaller in diameter than the first portion. A second interlocking portion of a succeeding blade member may be slidably inserted into the first interlocking portion. The second portion includes a pair of outwardly-directed tangs which abuttingly engage the inwardly-directed tangs of the first interlocking portion. A series of blade portions are thus interconnected and form a continuous shutter curtain which is selectively unfolded or retracted.
