Abstract
Abstract A rectangular box spring assembly of the disclosure includes a grid of crossing wires whose lateral edges have an improved construction in combination with formed wire springs that support the edges of the grid on lateral side members of a lower frame. Each lateral edge of the grid includes a pair of inboard and outboard longitudinally extending wires that are of a heavier gauge than the other wires of the grid. Each formed wire spring on the side frame members includes a pair of fishmouth sections extending upwardly from the frame and a connecting section that interconnects the fishmouth sections and supports the adjacent grid edge. The connecting section of each spring includes an inboard main portion and outboard end portions connected to the main portion. The outboard heavier gauge wire at each lateral grid edge is secured to the outboard end portions of the spring connecting sections to locate the grid. Additionally, end border wires of the assembly include bent end portions that overlap the outboard heavier gauge wires and have extreme ends that are turned to also overlie the inboard heavier gauge wire. The end portions of each end border wire are secured to the outboard heavier gauge wires by clips and to one of the laterally extending wires of the grid. Formed wire springs on end frame members support the end border wires and have a construction like the formed wire springs on the side frame members. Endmost laterally extending wires at each end of the grid are preferably secured to the inboard main portions of the connecting sections of the adjacent springs. Also, the outboard heavier gauge wires at the lateral edges of the grid are preferably shorter than the inboard heavier gauge wires.
