Cellular structure
Abstract
Abstract A cellular, honeycomb-like structure comprised of a plurality of elements in stacked or juxtaposed relation, and each having a pattern of corrugations. At least every other element is characterized by a plurality of pairs of sections of dissimilar length which each define a corrugation. The corrugations of adjacent elements internist to define closed, generally triangular cells. It is characteristic of the structure that the peaks or nodes of the corrugations of each element engage upon the internode portions or slopes of the corrugations of the adjacent element. During assembly this enables relative movement between the elements until internesting is achieved. It is also characteristic of the structure that each cell is defined by one complete internodal section and portions of a pair of internodal sections of two adjoining elements. Various configurations of the structure for various purposes are disclosed.
