To provide a flight safety frame for a drone (small sized unmanned aircraft) which is light and has high strength.SOLUTION: A flight safety frame for a drone includes: a roof frame (R) for covering the drone (A) from above; a wall frame (W) connected to a lower end part of the roof frame and totally enclosing a propeller (13) of the drone from a lateral direction; a plurality of horizontal cross beams (20) laid crosswise in a partial bridged condition to the middle of the wall frame so as to approach a tip part of an arm (11) projecting toward a radial direction of an airframe (10) in the drone; and a plurality of supporting legs (28) projecting toward a ground contact leg (12) of the drone from the different middle of the wall frame. All of the roof frame, the wall frame, the cross beams, and the supporting legs consist of fiber-reinforced plastic pipe material. The flight safety frame is set so that the middle of the cross beam is attached to a tip part of the arm projecting in a radial direction of an aircraft body in the drone or to a cover case (14) for a propeller revolution drive motor exiting at the tip part, and a projecting tip part of the supporting leg is attached to the ground contact leg of the drone, respectively, thereby the flight safety frame is used.SELECTED DRAWING: Figure 1

    【課題】ドローン(小型無人航空機)用の軽く高強度な飛行安全フレームを提供する。【解決手段】ドローン(A)を上方から覆う屋根枠(R)と、その屋根枠の下端部に連結されて、ドローンのプロペラ(13)を横方向から全体的に包囲する壁枠(W)と、ドローンにおける機体(10)の放射方向へ張り出すアーム(11)の先端部と接近するように、上記壁枠の途中へ部分的な橋渡し状態に横架された複数本の水平なクロスビーム(20)と、同じく壁枠の別異な途中からドローンの接地脚(12)に向かって張り出された複数本の支持脚(28)とを備え、上記屋根枠と壁枠、クロスビーム並びに支持脚がすべて繊維強化プラスチックの管材から成り、そのクロスビームの途中がドローンにおける機体の放射方向へ張り出すアームの先端部又はその先端部に存在するプロペラ回転駆動モーター用カバーケース(14)へ、上記支持脚の張り出し先端部がドローンの接地脚へ各々取り付け使用されるように設定した。【選択図】図1
