Title:
FOLDABLE BOOM
Document Type and Number:
Japanese Patent JP2021066188
Kind Code:
A
Abstract:
To provide a foldable boom having self-extension force and two-way stability that allows self-holding in two forms of a folded form and an extended form.SOLUTION: A plurality of units of cylindrical components 10 having elasticity are connected in one direction via a flexible first hinge element 101. The cylindrical components 10 are each divided into two parts: a first elastic deformation element 11 and a second elastic deformation element 12, by a face passing through a central axis of a boom main body 100 in an extended form. The first elastic deformation element 11 and the second elastic deformation element 12 are connected via a flexible second hinge element 102. The first elastic deformation element 11 can stably hold two forms that are curved to the same side in an extension direction and a direction orthogonal to the extension direction, and the second elastic deformation element 12 can stably hold two forms that are curved in the extension direction and an opposite direction to the extension direction. The cylindrical components 10 are configured such that the first elastic deformation element 11 and the second elastic deformation element 12 are alternately arranged and are folded into a zig-zag shape when they are folded.SELECTED DRAWING: Figure 1
