Border stabilizing member and method for making mattresses, cushions and the like using the same

An elongated stabilizing and reinforcing beam of resilient material which can be compressed under load and will thereafter return to its original shape upon removal of said load, for use in an innerspring assembly formed of springs, a plurality of such springs each having a longitudinal axis and being organized into rows and columns and forming a support surface with a top and bottom, with at least a first row of springs and a second row of springs spaced inboard from said first row and generally parallel to said first row, a gap thereby being formed between said first and second rows, and means for retaining said springs in said assembly,

• said stabilizing member having a longitudinal axis extending along its elongated length, and a cross-section orthogonal to said longitudinal axis having a major axis to said cross-section extending from top to bottom of said member, and a minor axis between the top and bottom orthogonal to said major axis of said member, said cross-section first gradually decreasing in width as measured orthogonal to said major axis progressing along said major axis from said minor axis and then towards the top and bottom gradually increasing in width toward the top and bottom of said member wherein the cross-section is symmetric about said major axis,
• said stabilizing member being located between said first and second rows of springs in said gap with said major axis thereof being aligned substantially parallel to said longitudinal axes of said springs.

An innerspring assembly comprising:

• a plurality of springs each having a longitudinal axis and being organized into rows and columns and forming a support surface with a top and bottom, with at least a first row of springs and a second row of springs spaced inboard from said first row and generally parallel to said first row, with a gap thereby being formed between said first and second rows;
• means for retaining said springs in said assembly;
• and
• an elongated stabilizing and reinforcing beam of resilient material which can be compressed under load and will thereafter return to its original shape upon removal of said load,
• said stabilizing member having a longitudinal axis extending along its elongated length, and a generally symmetric cross-section orthogonal to said longitudinal axis having a major axis and a minor axis, said major axis being of greater length than said minor axis, said cross-section having a perimeter shape where sides of said perimeter are at least partially defined by a modified rhombus-shape having truncated top and bottom ends with said major axis as measured along the diagonal between where two diametrically opposed corners would be with the side surfaces of the rhombus-shape being fully extended, and said minor axis as measured along another diagonal between the other two diametrically opposed corners, said perimeter shape being further defined by a trapezoid-shape superposed upon each end of said modified rhombus-shape on said major axis with the greater of the parallel sides of said trapezoid-shape being coextensive with each of said ends of said modified rhombus-shape,
• said stabilizing member being located between said first and second rows of springs in said gap with said major axis thereof being aligned substantially parallel to said longitudinal axes of said springs.
