Description
図3は本発明による実施例を簡略化した断面図である。この場合回転翼10は前部分11と後部の箱14とに分けられる。後部の箱14は、前部分11の後部にある壁とともに閉じられた容器16を形成する、変形可能な材料18からなる2つの空気かきを備える。上記の閉じられた容器16がガスの媒質の圧力で充填されたとき、変形可能な材料18は、本発明による回転翼10の表面の一部分(図1における番号14の参照で特定される)を形成して、上記回転翼は通常運転時、空気力学的に作動する。
図4は本発明の第1の参考例を示していて、完全な後部の箱14を伴う代わりに、回転翼10の吸引側の表面が拡大されている。上記拡大は、部分11の前部の表面に隣接する表面要素24である。
本発明の第2の参考例は図5aと5bで表される。図5aは変形可能な材料の巻き上げ部(winding)20を示していて、参照番号30は折りたたまれた状態の折りたたみ式アームを示している。ここでの仕組みは天幕の仕組みと似ている。
本発明の第3の参考例では、図6で示されているように、表面要素24が前部11の後側に回転するように取り付けられ前部11の吸引側が拡大されている。上記の場合表面要素24は表面要素24と前部11のキャリア構造との間に配置された圧縮バネ28によって支えられている。
図7は本発明の第4の参考例を示している。この第4の参考例では、表面要素24が前部11の後側に回転するように取り付けられる代わりに、表面要素24は、自身の縦軸のまわりを回転する回転スピンドル22の上に配置される。図7で示される位置には、表面要素24は再び回転翼10の空気力学的に作動する表面を拡大する。
図7で示されている参考例の変化形は図8aと8bで示されている。この場合図7の24の参照で示される表面要素は、図8aでは3つの翼のようなまたは薄板状の要素26に分割される。要素26は、図8aでは、分割されていることがはっきりとわかるように意図的にスペースが設けられている。実際の参考例では、当然のことながら、上記の3つの要素が、できるだけ近くの、さらに回転翼10の前部11にできるだけ滑らかに隣接した表面を形成するといった方法で配置される。
図14は本発明の参考例である回転翼のさらなる構造的変化形を示している。この場合、構造は、再び変形可能なフィルムに覆われていて、取り付け地点34に回転するように取り付けられた回転可能なループ(loop)32によって構築されている。回転翼の先(矢印で示されている)の方向への移動によって、上記回転ループは、例えば取り付け地点34のまわりを回転して、それ故後部の箱の形を変える。
さらに図9aから図14bは上記図4から図8bに対応する、代わりのまたは追加の参考例を示す。
