PROBLEM TO BE SOLVED: To solve the problem in indication that there is a danger of causing a radio wave hindrance in radio control of a drone due to being conventionally made of metal, since a conventional skeleton requires labor for assembling besides being nonflexible and heavy due to being a metallic framework, and canot be installed in various places such as slope land and an up-down site besides being narrow in space, and since a conventional net cannot be easily removed due to being a covering method, and is not easy in removal when wind is likely to become strong.SOLUTION: The problem is solved by suspending a cage molding a net by an auxiliary rope, by constituting a structure of a baseplate and a column holding tool corresponding to an inclination, a flexible column and a structural rope. For a structure using one unit having decided length×breadth×height as a base, assembling is executed while constituting the unit by four flexible columns, a structural rope stretched on the four sides for supporting the columns, and a support material. The structure is set up in a required extent, and the formed net is suspended therein to complete the cage.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】従来の骨組みは、金属製枠組みで融通が利かず重い上、組み立てに手間がかかる。スペースが狹い上傾斜地やアップダウンの敷地等 多彩な場所での設置は出来ない。従来のネットは覆う方法の為、取り外しが簡単に出来ず、風が強くなりそうな時の取り外しが容易でない。従来は金属製で、ドローンの無線操縦における電波障害を起こす危険性が有ると指摘されていた。【解決手段】傾斜に対応したベースプレートと支柱保持具、柔軟な支柱と構造用ロープで構造体を構成し、ネットを成形したケージを補助ロープで吊り上げる事で課題を解決した。組み立てはタテ×ヨコ×高さを決めた1ユニットを基本とする構造で、4本の柔軟な支柱と支柱を支える四方に張られた構造用ロープと支持材でユニットを構成しながら組み立て、必要な広さに設営し、その内側に成形したネットを吊り上げてケージを完成する。【選択図】図1
