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. In one embodiment 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. In another embodiment the sets of blades are secured in their open position by fastening the top two blades together with a fixture attached to the window. | |
