Abstract
A bedding or seating product is provided comprising a pocketed spring assembly made up of a plurality of parallel strings of springs joined to each other. Each string of springs comprises a row of interconnected pocketed springs. The pockets of fabric are vertically shortened with seams to create pockets of the same height, each containing a spring. The springs are vertically offset from one another due to the location of the seams. Upon an initial load, only some of the pocketed springs are compressed.
Claims29
A bedding or seating product comprising:
- a pocketed spring assembly comprising a plurality of parallel strings of springs, each of said strings of springs comprising a row of interconnected pocketed springs, each of said pocketed springs comprising a spring surrounded by a pocket of fabric, wherein within some of said strings of springs some of said pockets of fabric are of an identical vertical height and vertically offset relative to one another;
- and
- an upholstered covering surrounding said pocketed spring assembly.
A bedding or seating product comprising:
- a pocketed spring assembly comprising a plurality of parallel strings of springs, each of said strings of springs comprising a row of interconnected pocketed springs, each of said pocketed springs comprising a spring surrounded by a pocket of fabric, wherein within some of said strings of springs some of said pockets of fabric are of an identical vertical height and vertically offset relative to one another.
A bedding or seating product comprising:
- a pocketed spring assembly comprising a plurality of parallel strings of springs joined to each other, each of said strings of springs comprising a row of interconnected pocketed springs, each of said pocketed springs comprising a spring surrounded by a pocket of fabric,
- wherein said pocketed spring assembly has multiple regions of differing firmness, at least one of said regions having pockets of an identical height vertically offset from one another.
A bedding or seating product comprising:
- a pocketed spring assembly comprising a plurality of parallel strings of springs, each of said strings of springs comprising a piece of fabric wrapped around a row of aligned springs and secured along a longitudinal line of attachment, opposed plies of said piece of fabric being on opposite sides of the springs, said opposed plies of fabric being joined together between springs to create a plurality of pocketed springs of the same height, wherein said opposed plies of fabric are joined together in select locations to vertically offset some of the pocketed springs from other pocketed springs.
A string of springs for inclusion in a bedding or seating product, said string of springs comprising a tow of interconnected pocketed springs, each of said pocketed springs comprising a spring surrounded with a pocket of fabric, adjacent pocketed springs being the same height and vertically offset from one another in a portion of said string of springs.
A string of springs for inclusion in a bedding or seating product, said string of springs comprising a piece of fabric wrapped around a row of aligned springs and secured along a seam, opposed plies of said piece of fabric being on opposite sides of the springs, said opposed plies of fabric being joined together between springs to create a plurality of pocketed springs of the same height and vertically offset relative to one another, wherein said opposed plies of fabric are joined together in select locations to vary the location of the pocketed springs.
A method of manufacturing a pocketed spring assembly for use in a bedding or seating product, said method comprising:
- inserting a spring between opposed plies of fabric of a string of springs,
- joining said opposed plies of said fabric with seams to form a plurality of pockets, each of said pockets being the same height and encasing at least one spring, some of said springs being vertically offset from other springs in said string of springs due to the location of said seams, and
- joining said string of springs to adjacent strings of springs to form the pocketed spring assembly.
A method of manufacturing a pocketed spring assembly for use in a bedding or seating product, said pocketed spring assembly made of a plurality of strings of springs joined to each other, each of said string of springs comprising a piece of fabric folded such that said piece of fabric has opposed plies on opposite sides of a row of springs, said opposed plies being joined together between adjacent springs in said string of springs, said method comprising:
- inserting at least one spring between said opposed plies of fabric of a string of springs,
- joining said opposed plies in said string of springs in select locations to create a plurality of pockets of the same height such that said fabric encases said at least one spring in each of said pockets, wherein every other pocket within said string of springs is vertically offset from adjacent pockets, and
- joining said string of springs to adjacent strings of springs to form the pocketed spring assembly.
A method of manufacturing a pocketed spring assembly for use in a bedding or seating product, said pocketed spring assembly made of a plurality of strings of springs joined to each other, each of said string of springs comprising a piece of fabric folded such that said piece of fabric has opposed plies on opposite sides of a row of springs, said opposed plies being joined together between adjacent springs in said string of springs, said method comprising:
- inserting at least one spring between said opposed plies of fabric of a string of springs,
- joining said opposed plies in said string of springs in select locations to create a plurality of pockets such that said fabric encases said at least one spring in each of said pockets, wherein every pocket within a portion of said string of springs is of the same vertical height and every other pocket within said portion of said string of springs is vertically offset from adjacent pockets, and
- joining said string of springs to adjacent strings of springs to form the pocketed spring assembly.
