发明名称 Box spring assembly with interlocked formed wire components and method of assembling same
摘要 A box spring assembly which includes a generally rectangular frame, a plurality of upwardly extending wire springs mounted on the frame, and a wire grid supported on the upper ends of the springs so that the grid and springs cooperate to yieldably resist downwardly directed bedding loads. Each of the springs is formed at its upper end with an attaching portion that is structured so that it can be connected to the grid merely by moving it from an initial position to an interlocked position. This structure enables assembly of the grid and the springs without the requirement for the usual attaching clips.
