| 摘要 | A cellular structure having a plurality of walls extending along intersecting planes and together providing abutting cells, such walls being connected at their locations of intersection by cruciform sections and formed by flexing portions of a slit web material into planes disposed at angles to the plane of the original web material. | ||||||
| 权利要求 | 1. An article of manufacture of cellular construction includiNg a series of walls extending along each of a plurality of planes which intersect with each other, and spaced cruciform sections integrally connecting the walls to each other at the locations of intersection of their respective planes, said cruciform sections each having a central portion disposed in a common plane which passes through said series of walls and legs of helical shape extending between said central portion and the walls adjacent thereto. 2. An article as defined in claim 1 wherein the planes of said series of walls intersect at generally right angles with each other and said central portions of said cruciform sections are disposed in a common plane generally perpendicular to the planes of said series of walls. 3. An article as defined in claim 2 wherein each of said walls includes edges which are inclined away from adjacent cruciform sections and extend along intersecting planes to thereby provide diagonally opposed corners. 4. An article as defined in claim 3 further including a continuous flat member disposed generally parallel to the common plane of the central portion of the cruciform section and through which portions of the corners of said walls project, and wherein the projecting portions of said corners are deformed whereby the continuous flat member is locked in place. 5. An article as defined in claim 2 wherein at least the outermost edges of each of said walls are generally parallel to the common plane of the central portions of the cruciform sections, and further including a continuous flat member attached to the outermost edges of said walls at least along one side of the cellular construction. |
