Patent Searching and Data

Document Type and Number:
Japanese Patent JP2019002433
Kind Code:
To provide a three-dimensional structure whose strength in a specific direction is lower than a strength in the other direction (which has anisotropy with respect to the strength) and which is destroyed to absorb an impact force that acts in the specific direction.SOLUTION: A three-dimensional structure 1 is configured by: (a) separately disposing a pair of annular frame-shaped body parts in such a manner that the annular frame-shaped body parts face each other and connecting the pair of frame-shaped body parts via multiple rod-shaped parts, thereby forming a lattice structure unit body 6 (7); (b) connecting the multiple lattice structure unit bodies 6 (7), thereby forming an H-shaped lattice structure 2 from a pair of longitudinal-side skeleton parts 4 and 4 and a lateral-side skeleton part 5 connecting the pair of longitudinal-side skeleton parts 4 and 4; (c) positioning the lattice structure 2 in such a manner that the rod-shaped part of the lattice structure unit body 6 (7) is in a direction of extension of the lateral-side skeleton part 5; and (d) connecting multiple lattice structures 2 in such a manner that the lateral-side skeleton parts 5 of the lattice structures 2 are aligned in the same direction.SELECTED DRAWING: Figure 1
