Zusammenfassung: | To provide a buffer material with excellent buffer performance.SOLUTION: A buffer material 1 includes a buffer part 10 which has a three-dimensional shape formed by walls 11 whose outline is defined by a pair of curved surfaces in parallel. The buffer part 10 includes at least one three-dimensional structure part 12 obtained by changing the shape of a unit structure U', which is based on the unit structure of the Schwarz P structure with thickness added to it. The shape of the three-dimensional structure part 12 in an unloaded condition is a shape obtained by changing the shape of the structure U', following a change of the shape of the unit space S', which is a regular hexahedron-shaped space occupied by the unit structure U', into to a pedestal-shaped space S.SELECTED DRAWING: Figure 1
【課題】緩衝性能に優れた緩衝材を提供する。【解決手段】緩衝材1は、並行する一対の曲面によって外形が規定される壁11にて形作られた立体的形状を有する緩衝部10を備える。緩衝部10は、シュワルツP構造の単位構造を基準にこれに厚みを付けた単位構造体U'を形状変化させることで得られる三次元構造部12を少なくとも1つ以上含んでいる。三次元構造部12の無負荷状態における形状は、上記単位構造体U'が占有する正六面体形状の空間である単位空間S'を台状の空間Sに形状変化させた場合に、これに追従するように上記単位構造体U'を形状変化させることで得られる形状である。【選択図】図1 |
