Spring assembly

A spring assembly comprising:

• a plurality of rows of coils, each of said rows being formed from a single continuous piece of wire and each of said rows containing a plurality of coils interconnected by Z-shaped interconnecting segments, alternate ones of said Z-shaped interconnecting segments being disposed in the planes of the upper and lower surfaces of said spring assembly, portions of said Z-shaped interconnecting segments extending beyond the periphery of said coils, the axes of said coils being disposed perpendicular to the upper and lower surfaces of said spring assembly,
• sections of each of said Z-shaped interconnecting segments of each row being juxtapositioned relative to Z-shaped interconnecting segments of an adjacent row, said juxtapositioned sections being located on opposite sides of said coils,
• helical spring means extending parallel to said rows for the length of said rows, said helical spring means being wound through said juxtapositioned sections of said Z-shaped interconnecting segments so as to secure said rows of coils in an assembled relation, and
• said juxtapositioned sections of said Z-shaped interconnecting segments being radiused, the center of the radii of said juxtapositioned sections being located in a diametral plane of said coils, and the center of the radii of the juxtapositioned sections on opposite sides of each of said coils being located in the same diametral plane so that compression of said assembled coils does not cause the axes of said coils to be moved laterally or the coils to be twisted when fully compressed.

• sections of each of said interconnecting segments of each row being overlapped relative to interconnecting segments of an adjacent row, said overlapped sections being located on opposite sides of said coils,
