Title:
PLANAR STRUCTURAL BODY
Document Type and Number:
Japanese Patent JP2022146767
Kind Code:
A
Abstract:
To provide a technique capable of adjusting a planner structural body being deformable into a plane form and a three-dimensional form into three-dimensional shape aiming at a whole planner structural body and capable of easily holding the three-dimensional shape.SOLUTION: A planner structural body comprises: a plurality of surface parts 12; and a folding line 14 that is provided at boundaries of the plurality of surface parts 12 and at least partially curved. Each of the surface parts 12 is anisotropic in bending rigidity by linearly extending from the folding line 14 and having a plurality of hollow parts in closed cross-sectional shape. The plurality of hollow parts forms linear elements 26 when the planner structural body is folded along a curve. In the whole variable range area of the folding angle on the folding line 14, the planner structural body can be folded along a curve without crossing all of the surface parts 12 while maintaining the linear elements 26, and maintaining the linear elements 26 formed by the hollow parts adjacent to each other in the positional relation without torsion, in all of the surface parts 12.SELECTED DRAWING: Figure 4
