Abstract: A box spring for supporting a bedding mattress. The box spring includes a rectangular base frame, a plurality of modular spring elements mounted atop the base frame, and a wire grid mounted atop the modular spring elements. Each of the modular spring elements comprises a horizontal straight center section terminating in horizontal plane curved end sections, at least some of the curved end sections having single revolution coil springs extending vertically downwardly therefrom. The modular spring elements are arranged in parallel rows, said adjacent spring elements of each row having aligned straight center sections and overlapping curved sections. The overlapping curved center sections of adjacent modular spring elements are connected by transverse wires of the grip top, which transverse wires have generally U-shaped bights or hooks from therein received over the overlapping curved sections and crimped shut to secure adjacent modular spring elements of multiple rows of modular spring elements to one another.

Abstract: A bedding unit spring has an upper portion attached to a grid, a lower portion attached to a frame, and a vertically collapsible midportion which connects the upper portion to the lower portion. The upper portion of a spring may have two transverse bars at its ends, a third transverse bar at its center, and a center bar formed of two sections which are on opposite sides of the third transverse bar. The center bar sections are directed toward the midportions of the end transverse bars.

Abstract: 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 has a body comprised of two side-by-side arcuate portions formed integral at their upper ends with torsion bars that are connected by a connecting bar located between the arcuate portions. The arcuate body portions thus resist bedding loads with bending stresses and without any areas of stress concentration that would cause early spring failure. The torsion bars in each spring divide the spring load and resist bedding loads principally with torsional stresses, the combination of both bending and torsional stresses in the springs enabling increased load-resisting capabilities in the springs with a resulting efficient use of spring wire material.

Abstract: A box spring assembly having a rectangular frame mounting a plurality of lateral support slats, formed wire torsion springs affixed to said slats and a metal grid interconnecting said springs. To minimize sag resulting from body weight, the support slats adjacent the lateral center line of the frame are first reinforced with U-shaped metallic bars which rest the wooden slats. In addition, the number or density of lateral slats adjacent this center line are increased leaving a lower density of slats adjacent the head and foot ends of the assembly. This arrangement of lateral slats permits reorientation of the formed wire spring units which further results in greater lateral stability of the box spring unit. The assembly is then completed by adding one or more insullating pads for cushioning and a fabric cover.

The varying thickness and cross sectional area of the sheet provides for minimum deflection at the center portion of the sheet when downward force is applied thereto while maximum deflection occurs at the first and second intermediate section.
