Pillow support structure

Abstract

A pillow support structure includes first and second complementary polyhedral sections that each provide a flat, top surface and a sloped surface adjacent to the top surface, and complementary attachment surfaces designed to adjust the spacing between the first and second complementary polyhedral units.

1 . A pillow support structure, comprising:
 a first section and a second section each having a pair of opposed right trapezoidal sides that are connected together by a top surface and bottom surface disposed perpendicularly to the opposed right trapezoidal sides, the bottom surface having a length exceeding a length of the top surface, the opposed right trapezoidal sides also connected together by a sloped surface extending from an edge of the top surface at an obtuse angle and to an edge of the bottom surface at an acute angle, and also connected together by an end surface opposed to the sloped surface and perpendicular to the top and bottom surfaces; and   a rectangular sheet of material extending from the bottom surface of the first section beyond the sloped surface;   wherein a top surface of the rectangular sheet of material and the bottom surface of the second section have complementary attachment structures for temporary attachment therebetween providing adjustable spacing between the sloped surfaces of the first section and the second section;   wherein each side or surface of the first section and second section is provided by an individual panel of fabric, and the individual panels of fabric are attached together to provide a fabric shell;   wherein the individual panels of fabric are attached together at seams by stitches; and   wherein each individual panel of fabric represents only one side or surface of a section.

         3 . (canceled) 
     
     
         4 . The pillow support structure of  claim 1 , further comprising a filler material that fills the fabric shell, the filler material chosen from polyurethane memory foam, polystyrene beads, polyester, cotton, feather, and down. 
     
     
         5 . The pillow support structure of  claim 4 , further comprising a zipper disposed in the fabric shell of the first section and second section that provides access to the filler material. 
     
     
         6 . The pillow support structure of  claim 1 , wherein the fabric is chosen from cotton, polyester, denim, suede, corduroy, wool, and microfiber, and blends thereof. 
     
     
         7 . The pillow support structure of  claim 1 , wherein the complementary attachment structures are chosen from hook and loop fasteners, magnets, two-sided tape, and snap fasteners. 
     
     
         8 . A method, comprising:
 assembling first and second fabric casings by stitching or sewing individual panels of fabric together at seams, the individual panels of each fabric casing comprising two opposed right trapezoid-shaped or other quadrilateral-shaped panels and a plurality of rectangular panels connecting the two opposed right trapezoid-shaped or other quadrilateral-shaped panels therebetween comprising a top, bottom, and end rectangular panel and a sloped rectangular panel extending from the top rectangular panel to the bottom rectangular panel;   attaching a sheet of material to the bottom rectangular panel of fabric of the first fabric shell that extends beyond the bottom rectangular panel; and   attaching complementary attachment structures to a top surface of the sheet of material and to the bottom rectangular panel of the second fabric shell;   wherein when each fabric casing is filled, each individual panel of fabric represents only one side of a polyhedral structure formed by the fabric casing.   
     
     
         9 . The method of  claim 8 , further comprising attaching a zipper to the first and second fabric shells designed to provide access to an interior of the first and second fabric shells. 
     
     
         10 . The method of  claim 9 , further comprising filling the first and second fabric shells with a filler material. 
     
     
         11 . The method of  claim 10 , wherein the filler material is chosen from polyurethane memory foam, polystyrene beads, polyester, cotton, feather, and down. 
     
     
         12 . A pillow support structure, comprising:
 first and second complementary polyhedral sections that each provide a plurality of sides and surfaces including a flat, top surface and a sloped surface adjacent to the top surface; and   complementary attachment surfaces designed to adjust the spacing between the first and second complementary polyhedral sections;   wherein each side or surface of the first section and second section is provided by an individual panel of fabric, and the individual panels of fabric are attached together to provide a fabric shell; and   wherein the individual panels of fabric are attached together at seams by stitches;   wherein each individual panel of fabric represents only one side or surface of a polyhedral section.   
     
     
         13 . The pillow support structure of  claim 12 , wherein the first and second complementary polyhedral sections are right trapezoidal prisms. 
     
     
         14 . The pillow support structure of  claim 13 , wherein the right trapezoidal prisms comprise an outer fabric shell surrounding a filling material. 
     
     
         15 . The pillow support structure of  claim 14 , wherein the outer fabric shell comprises fabric chosen from cotton, polyester, denim, suede, corduroy, wool, and microfiber, and blends thereof. 
     
     
         16 . The pillow support structure of  claim 14 , wherein the filler material is chosen from polyurethane memory foam, polystyrene beads, polyester, cotton, feather, and down. 
     
     
         17 . The pillow support structure of  claim 12 , wherein a first complementary attachment surface is provided by a sheet of fabric attached to and extending beyond the first complementary polyhedral section, and the second complementary attachment surface is a bottom surface of the second complementary polyhedral section. 
     
     
         18 . The pillow support structure of  claim 12 , wherein the complementary attachment surfaces have complementary attachment structures chosen from hook and loop fasteners, magnets, two-sided tape, and snap fasteners. 
     
     
         19 . The pillow support structure of  claim 12 , wherein the first and second complementary polyhedral sections are trapezoidal prisms having a base that is wider than the flat, top surface.
