    • PROBLEM TO BE SOLVED: To realize an ideal ratio between a draw-out force and a pull-in force and a new method for advantageous behavior for winding up for blinds such as a joint arm sunshade, a drop arm sunshade, a sun room sunshade, a vertical sunshade, a sunshade for window or the like; which are equipped with a sunshade cloth (4): a winding-up shaft supported in a rotatable manner while forming a cloth roll (wound cloth); and a sunshade equipped with a device (5) to draw-out sunshade cloth.
      SOLUTION: A draw-out device (5) for tensioning the sunshade cloth (4) by a magnetic attraction which occurs between a magnet (10) and a target member (13) pulled by the magnet can be fixed until the magnetic attraction is transcended at least at a predetermined draw-out position. If an excessive load such as gust of wind occurs, the fixation can be automatically peeled off by the magnetic attraction. Also, the best ratio of forces is acquired at the time of draw-out and pull-in, and an advantageous wind-up behavior can be realized while a high stability is kept against wind.

    • 要解决的问题:为了实现拉出力和拉入力之间的理想比例,以及用于诸如关节臂遮阳帘,落臂遮阳罩,太阳室遮阳帘等遮阳帘的有益行为的新方法 ,垂直遮阳伞,窗户遮阳伞等; 它们装有遮阳布(4):可旋转地支撑的卷绕轴,同时形成布卷(卷布); 以及装有装置(5)的遮阳伞,用于拉出遮阳布。 解决方案:用于通过在磁体(10)和由磁体拉动的目标构件(13)之间发生的磁吸引力来张紧遮阳布(4)的拉出装置(5)可以被固定,直到磁吸引力超过 至少在预定的拉出位置。 如果发生诸如阵风的过度负荷,则可以通过磁吸引力自动地剥离固定。 此外,在拉出和拉入时获得最佳的力比,并且可以实现有利的卷起行为,同时保持高风险的稳定性。
