Abstract
A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly.
Claims20
A bedding or seating product comprising:
- a pocketed spring assembly comprising a plurality of parallel strings of springs joined together to form a pocketed spring assembly core;
- a dimensionally stabilizing substrate secured to one of top and bottom surfaces of the pocketed spring assembly core to create a pocketed spring assembly;
- a scrim sheet secured to the other of the top and bottom surfaces of said at least some of the strings of the pocketed spring assembly,
- wherein said dimensionally stabilizing substrate is thicker and more rigid than the scrim sheet, the dimensionally stabilizing substrate being flexible enough in the height of the pocketed spring assembly to allow the pocketed spring assembly to be roll packed,
- cushioning materials;
- and
- an upholstered covering encasing said pocketed spring assembly and cushioning materials.
A bedding or seating product comprising:
- a pocketed spring assembly comprising a plurality of parallel strings of springs joined together to form a pocketed spring assembly core;
- a dimensionally stabilizing substrate secured to one of top and bottom surfaces of the pocketed spring assembly core to create a pocketed spring assembly;
- and
- a scrim sheet secured to the other of the top and bottom surfaces of the pocketed spring assembly core;
- wherein said dimensionally stabilizing substrate is thicker and more rigid than the scrim sheet, the dimensionally stabilizing substrate being flexible enough in the height of the pocketed spring assembly to allow the pocketed spring assembly to be roll packed.
A pocketed spring assembly comprising:
- a pocketed spring assembly core comprising parallel strings of springs joined together, each of said strings comprising a plurality of individually pocketed springs, each of said strings comprising a piece of fabric joined along a longitudinal seam, first and second opposed plies of fabric being on opposite sides of the springs, a plurality of pockets being formed along a length of said string by transverse seams joining said first and second plies, at least one spring being positioned in each said pocket;
- a dimensionally stabilizing substrate being secured to a portion of pocketed spring assembly core with adhesive;
- and
- a scrim sheet secured to another portion of the pocketed spring assembly core with adhesive to facilitate handling of the pocketed spring assembly, the dimensionally stabilizing substrate being thicker and more rigid than the scrim sheet, but bendable for purposes of roll packing the pocketed spring assembly.
A pocketed spring assembly having a length, width and height, said pocketed spring assembly comprising:
- a plurality of parallel strings of springs joined together, each of said strings comprising a plurality of individually pocketed springs, each of said strings comprising a piece of fabric joined along a longitudinal seam, first and second opposed plies of fabric being on opposite sides of the springs, a plurality of pockets being formed along a length of said string by transverse seams joining said first and second plies, at least one spring being positioned in each said pocket;
- a dimensionally stabilizing substrate secured directly to either a top surface or a bottom surface of at least some of the strings;
- a scrim sheet secured directly to the other surface of the top and bottom surfaces of said at least some of the strings,
- wherein said dimensionally stabilizing substrate is thicker than the scrim sheet.
