飛行体。
以下、本発明の実施の形態による飛行体について、図面を参照しながら説明する。
図1乃至図3に示されるように、本発明の実施の形態による飛行体1は、プロペラ2(揚力発生部:回転翼)と、プロペラ2を回転させるためのモータ3と、モータ3が取り付けられているアーム4と、アーム4に設けられ荷物52(搭載対象物)が搭載される搭載部5と、支持部材6と、位置決め部材7とを備えている。飛行体1は図の矢印Dの方向を進行方向としている(詳しくは後述する)。
続いて、図1及び図4を参照して、本実施の形態による飛行体1の飛行態様について説明する。なお。以下の説明においては、説明を明確にするため、上昇時、水平移動時、下降時の3つの態様をそれぞれ説明するが、例えば、上昇しながら水平移動を行う等のように、これらの態様の組み合わせによって飛行する態様も当然含まれる。
ユーザが操作部を備えたラジオコントロール用の送信機を操作して、飛行体のモータ3の出力を上昇させて、プロペラ2の回転数を増加させる。プロペラ2が回転することによって、飛行体1を浮上させるために必要な揚力が鉛直上向きに発生する。当該揚力が飛行体1に働く重力を超えると飛行体1は、地面を離れて出発地を離陸する。
飛行体1は、水平方向に進行する場合には進行方向に向かって前方にあるプロペラ2の回転数よりも、進行方向に向かって後方にあるプロペラ2の回転数を多くするように制御される。従って、図1に示されるように、進行方向に水平移動時は、飛行体1は前傾姿勢をとる。このとき、ヒンジ50があることによって、荷物52の向きは水平に保たれている。さらに位置決め部材7があることによって支持部材6の位置が第2の位置決め位置(搭載部5が上下方向および水平方向に移動することを可能にする位置)で位置決めされている。
飛行体1は、図4に示すように、目的地に着陸して、搭載部5に搭載されている荷物52を目的地に下ろす。即ち、目的地において、飛行体1と荷物52は分離される。飛行体1と荷物52の分離は、荷物52が搭載部5から切り離すことによって行われる。本実施の形態における飛行体1は、軽量化を図るために着陸脚を有していない。従って、着陸時には、搭載された荷物52自身が着陸脚の機能を有することとなる。しかしながら、本実施の形態における飛行体1は、位置決め部材7があることによって、支持部材6の位置が第1の位置決め位置(搭載部5が上下方向および水平方向に移動することを阻止する位置)で位置決めされている。従って、本実施の形態における飛行体1は、荷物52を搭載部5に固定した状態で、目的地に着陸することができる。
位置変更部材は、図6及び図7に示すように、フック90、連結棒91、リンク部材92、ブロック材93で構成されてもよい。フック90は、側面視においてL字状に屈曲して腕部90Aと腕部90Bが形成されたブロック材である。腕部90Bの先端は、搭載部5に軸支されるとともに、腕部90Bの中間部には連結棒91の一端が軸によって回動可能に連結されている。連結棒91の他端はリンク部材92の一端が軸によって回動可能に連結されている。リンク部材92の他端は、搭載部5に固定されたブロック材93に軸支されている。この変形例では、腕部30の先端と、搭載部5との接離状態に応じて、搭載部5の位置が第1の位置決め位置又は第2の位置決め位置に切り替わる。すなわち、搭載部5の位置が第1の位置決め位置で位置決めされている状態においては、腕部30の先端は搭載部5に当接する。一方、搭載部5の位置が第2の位置決め位置で位置決めされている状態においては、腕部30の先端は搭載部5との当接位置から離間する。
