機体フレーム

To provide a fuselage frame which has a lightweight and strong structure, can be easily transported, and can suppress storage space. SOLUTION: A plurality of units 10 (10') having a substantially pyramidal shape composed of a plurality of tubular members 11 (11') and 12 (12') are provided, and each unit 10 (10') has a plurality of base tubular shapes. The ends of the members 11A-11D (11A'-11D') are connected to form the base B of the pyramid, and one end is connected to the ends of the base tubular members 11A-11D (11A'-11D'). The side tubular members 12 (12') are connected to each other at the other ends to form a pyramid apex P, and a plurality of units 10 are detachably connected to form each unit 10 (10'). are arranged substantially on the same plane to form the upper surface, and the apex P of the pyramid of each unit 10 (10') is arranged below the upper surface. [Selection drawing] Fig. 1A 軽量で強固な構造を有するとともに、容易に搬送でき、保管スペースを抑制できる機体フレームを提供することにある。【解決手段】 複数の管状部材11(11’)、12(12’)で構成された略角錐形状を有するユニット10(10’)を複数備え、ユニット10(10’)は、複数の底辺管状部材11A~11D(11A’~11D’)の端部が連結されて角錐の底面Bが形成され、底辺管状部材11A~11D(11A’~11D’)の端部に一方の端部が連結された側辺管状部材12(12’)が他方の端部で互いに連結されて角錐の頂点Pが形成され、複数のユニット10が着脱可能な状態で連結されて、各々のユニット10(10’)の角錐の底面Bが略同一面上に配置されて上面を形成し、各々のユニット10(10’)の角錐の頂点Pが上面より下側に配置されている機体フレーム2を提供する。【選択図】図1A
