发明名称 Box spring assembly with improved stiffness characteristics
摘要 A box spring assembly which includes a generally rectangular frame, a plurality of wire springs mounted on the frame and connected to each other so as to yieldably resist downwardly directed bedding loads. Each of the springs has an elongated body portion arranged above the frame and downwardly extending end portions, each of the end portions having an upper section and a lower section which are located in planes that are upright and generally perpendicular to each other with each of the sections being comprised of integral legs arranged in a generally V-formation rotated about ninety degrees and with the included angle between the legs being less than ninety degrees. This construction enables the spring end portions to yieldably resist bedding loads with both bending and torsional stresses thereby enabling increased load-resisting capabilities in the spring end portions with a resulting efficient use of spring wire material.
