SHADE DEVICE
PROBLEM TO BE SOLVED: To make it possible to easily winding screen holding means together with a screen on a winding shaft in a case.SOLUTION: A first holding member 70 and a second holding member 80 of holding means 20 are juxtaposed in an extended state in a lengthwise direction to hold a screen 10, and accommodate the screen in a case 50 in a wound state of being wound on a winding shaft 31. The first holding member 70 has elasticity for restoring the extended state from the wound state, and is curved in an arc shape in a width direction thereby maintaining the extended state. The second holding member 80 comprises a constant load spring having elasticity for restoring the wound state from the extended state, and is curved in an arc shape thereby maintaining the extended state, and is deformed to a convex curved surface side thereby restoring the wound state. The first holding member 70 and the second holding member 80 are curved in direction opposite to each other in the extended state, and are wound on the winding shaft 31 in an overlapped state.SELECTED DRAWING: Figure 6
【課題】スクリーンの保持手段をスクリーンとともにケース内の巻取シャフトに容易に巻き取る。【解決手段】保持手段２０の第１保持部材７０と第２保持部材８０は、長さ方向への伸張状態で並置されてスクリーン１０を保持し、巻取シャフト３１に巻き取られた巻取状態でケース５０に収容される。第１保持部材７０は、巻取状態から伸張状態に復元する弾性を有し、幅方向において弧状に湾曲して伸張状態を維持する。第２保持部材８０は、伸張状態から巻取状態に復元する弾性を有する定荷重ばねからなり、弧状に湾曲して伸張状態を維持するとともに、凸状の湾曲面側に変形して巻取状態に復元する。第１保持部材７０と第２保持部材８０は、伸張状態で互いに反対方向に湾曲し、重なる状態で巻取シャフト３１に巻き取られる。【選択図】 図６
