<p>PROBLEM TO BE SOLVED: To smoothly extract panels to the outside of a building and store them to the outer wall side by setting a support arm to a fixed length, and forming the panels into a circular arc curve shape capable of following the rotation of the tip section of the support arm. SOLUTION: Panels 2a, 2b, 2c and guides R are formed into a circular arc curve shape along the rotating locus of the tip section of a support arm 10. When an operation cord 100 is pulled, a roller bearing 52 at the tip section of the support arm 10 is moved to a block 8 on the outside of the lowermost panel 2c. When the operation cord 100 is further pulled, the connecting tool 50 of the lowermost panel 2c is moved to a block 8 on the outside of the guide R of the middle panel 2b to form a half-opened shade. The panels 2b, 2c of second and third stages follow the rotating locus of the tip section of the single support arm 10 and can be smoothly extracted to the outside of a building and stored to the outer wall side without requiring the expanding/shrinking actions of the support arm 10.</p> |
