Japanese Patent JP2019002556
Kind Code:
To provide a structure in which a plurality of prescribed parallelograms are regularly arranged on parallel two planes.SOLUTION: A plane geometrical figure is obtained without forming a clearance by alternately arranging, at a plane figure which is tiled of a first parallelogram and a symmetric second parallelogram without a clearance: a first band-like figure which is obtained by a cut line for alternately connecting a first line and a second line when setting a side non-parallel with a symmetric line of the first parallelogram as the first line, and setting a diagonal line with an apex being an obtuse angle of the second parallelogram as an end point as the second line; and a second band-like figure having a third parallelogram and a fourth parallelogram which are obtained by connecting opposing apexes of the first parallelograms which oppose each other when the two first band-like figures are arranged in parallel with each other. Then, a ridge-folding parallelogram for ridge-folding respective sides with respect to a plurality of the third parallelograms and a valley-folding parallelogram for valley-folding the respective sides are folded so as to be alternately arranged.SELECTED DRAWING: Figure 2
