ABSTRACT:
A blind for installation adjacent the semi-circular portion of an arched window is disclosed which is based on a U-shaped frame, which frame is adapted for mounting along the face of the window at the bottom of the semi-circular portion thereof. Two sets of blades fan out evenly from the ends of the U-shaped frame around an axis and meet at the top of the window, thereby forming a semi-circular array. Handles rotating from the blade axis are fastened onto the last blade in each set, and meet at the top where they are locked into position by latches mounted on the end of a support arm also rotating from the blade axis.
