WINDING SPEED CONTROL MECHANISM, SHIELD WINDING DEVICE WITH WINDING SPEED CONTROL MECHANISM, OPENING/CLOSING MEMBER
To reduce the winding speed from a position just before the top position of the screen to the top position.SOLUTION: In the winding cylindrical shaft, the starting top, the position adjustment top, the nut, the damper connection member, and the position reset spring are attached to a threaded shaft member. The starting top has a threaded hole that screws into the threaded shaft portion. The outer peripheral surface of the starting top has an uneven shape that conforms to the inner wall of the winding cylindrical shaft. When the starting top is on the threaded shaft portion, it moves in a linear direction in accordance with the rotation of the winding cylindrical shaft. When the screen is wound up to a height just before the top position, the starting top engages with the position adjustment top to rotate the threaded shaft member, and this rotation is decelerated by the rotary damper via the damper connection portion. As a result, the screen is wound up slowly.SELECTED DRAWING: Figure 3
【課題】スクリーンの最上位置の手前位置から最上位置までの巻取り速度を減速させる。【解決手段】巻取筒軸内において、起動コマ、位置調整コマ、ナット、ダンパー接続部材、位置リセット用ばねがねじ溝付き軸部材に取付けられている。起動コマには、ねじ軸部に螺嵌するねじ孔が設けられている。起動コマの外周面は巻取筒軸の内壁に沿う凹凸形状を有する。起動コマは、ねじ軸部上にあるとき、巻取筒軸の回転に合わせて直線方向に移動する。スクリーンが最上位置の手前位置の高さまで巻き取られると、起動コマが位置調整コマと噛み合ってねじ溝付き軸部材を回転させ、この回転はダンパー接続部を介してロータリーダンパーで減速される。このため、スクリーンはゆっくりと巻き上げられる。【選択図】図３
