SPRING ASSEMBLY |
摘要 |
A spring assembly for mattresses, innersprings, and the like. The assembly comprises rows of coils, each row comprising a continuous length of wire formed into a plurality of coils interconnected by Z-shaped wire segments alternately disposed at the top and bottom of the coils. Adjacent rows of coils are connected by a helical wire wound through overlapping Z-shaped wire segments. The overlapping connected segments on opposite sides of each coil are located in a common diametrical plane of the coil so that complete compression of the coil does not result in the coil being pulled laterally, twisted and distorted. |
