  • Semi-circular window shade
    Patent number: 5662153
    Abstract: A frame supports a fan-shaped pleated shade that is rotated from a folded open position to an unfolded closed position so that the shade covers a semi-circular window adjacent to the shade. Two pull-cords are attached to the shade to rotate it between its two extreme positions. The cords are routed over circular surfaces so that they apply a normal force to the shade throughout its movement.
