Abstract

A protective member configured as a protective member that is mountable to an aerial vehicle having a body and at least one rotor held on the body, and includes a plurality of support members that are connectable to the aerial vehicle and have a flexible member stretched between distal end portions thereof so as to surround an outside of the body in planar view, wherein at least one of the plurality of support members has a tension adjusting mechanism that is capable of adjusting a tension applied to the flexible member in a stretching direction, by changing a distance from a center of the body to the distal end portion.

Claims (21)

1. Flight equipment comprising:

an aerial vehicle having a body and at least one rotor held on the body; and

a protective member having a plurality of support members that are connected to the aerial vehicle and a plurality of flexible members stretched between distal end portions of the plurality of support members so as to surround an outside of the body, wherein

the aerial vehicle or the protective member has at least one tension adjusting mechanism that adjusts a tension applied to at least one of the plurality of flexible members in a stretching direction, by changing a distance from a center of the body to a distal end portion of at least one of the plurality of support members.

2. The flight equipment according to claim 1 , wherein

at least one of the plurality of support members has: a fastenable part that is configured to be fastened to the aerial vehicle, and a movable part that has a proximal end portion overlapping with, and held on, the fastenable part, and has a distal end portion holding a corresponding one of the plurality of flexible members, and wherein an overlap length between the movable part and the fastenable part is adjustable by a corresponding one of the at least one tension adjusting mechanism.

3. The flight equipment according to claim 2 , wherein

each movable part is connected to a corresponding fastenable part by a corresponding tension adjusting mechanism.

4. The flight equipment according to claim 1 , wherein

at least one of the plurality of support members has: a fastenable part that is configured to be fastened to the aerial vehicle, and a movable part that has a proximal end portion pivotably connected to a distal end portion of the fastenable part and has a distal end portion holding a corresponding one of the plurality of flexible members, wherein an angle formed by the movable part and the fastenable part is adjustable by a corresponding one of the at least one tension adjusting mechanism.

5. The flight equipment according to claim 1 , wherein

the at least one tension adjusting mechanism moves one of the distal end portions in a plane perpendicular to a rotation axis of a corresponding one of the at least one rotor.

6. The flight equipment according to claim 1 , wherein:

at least one of the plurality of flexible members is band-shaped.

7. The flight equipment according to claim 6 , wherein

a thickness direction of the at least one band-shaped flexible member is perpendicular to a rotation axis of a corresponding one of the at least one rotor.

8. The flight equipment according to claim 1 , wherein at least one of the at least one tension adjusting mechanism includes at least one of a fastened side lever, a movable side lever, an adjusting screw and a lock nut.

9. A protective member mountable to an aerial vehicle having a body and at least one rotor held on the body, the protective member comprising:

a plurality of support members that are connectable to the aerial vehicle and a plurality of flexible members stretched between distal end portions of the plurality of support members so as to surround an outside of the body, wherein

at least one of the plurality of support members has: a tension adjusting mechanism that adjusts a tension applied to a flexible member in a stretching direction by changing a distance from a center of the body to a corresponding distal end portion.

10. The protective member according to claim 9 , wherein each tension adjusting mechanism includes at least one of a fastened side lever, a movable side lever, an adjusting screw and a lock nut.
