Patent ID: 8474764

Claim:
A lightweight three-dimensional wire structure, having multiple wires which are connected to each other and cross over in three-dimensional space for defining a plurality of cells, the wire structure comprising: helically wound wires; multiple helical first wires having first wire axes, said first wires being disposed in a plane with said first wire axes parallel to one another, said first wires crossing over at intersection points for defining a first wire mesh being connected in an x and y direction, two adjacent said first wires being connected by one intersection point per winding; multiple helical second wires, having second wire axes, said second wire axes being parallel to one another and disposed transversely in relation to said first wire axes, said second wires defining a second wire mesh within said plane, said second wires intersecting with one another and with said first wires of the first wire mesh at said intersection points; multiple helical third wires having third wire axes, said third wire axes being parallel to one another, said third wires being displaced in a z direction in relation to said plane, said third wires crossing over one another and said third wires crossing over said first and second wires such that that each second one of the second wires is crossed over; and multiple helical fourth wires having fourth wire axes, said fourth wire axes being parallel to one another and being provided transversely to said third wire axes, said fourth wires defining a second wire mesh within a second plane, said fourth wires intersecting with one another at said intersection points and said fourth wires intersecting with said intersection points.
