Contour Sheets and Methods of Making Thereof

Abstract

Contour sheets or fitted sheets having a mattress cover surface and a plurality of side surfaces are provided with at least one resilient member extendible in a vertical direction along the depth of a mattress in at least a portion of one of the side surfaces. Alternatively, sets of resilient members sandwiched between one or more layers of fabrics can be provided to prevent direct exposure to heat and other detrimental conditions that the contour sheets may be subjected to during routine wear and laundry. A method of making such contour sheets can include steps of cutting a generally polygonal shaped cut-out to form an opening at the corners of a base fabric, coupling at least one resilient member along at least one edge of the opening and sewing adjacent edges of the opening together.

         4 . The method of  claim 1 , wherein the step of coupling comprises the step of sewing said at least one resilient member along corners that conform with corners of the mattress. 
     
     
         5 . The method of  claim 1 , further comprising:
 (i) cutting a generally polygon shaped cutout at one or more corners of the sheet to form an opening with at least two edges;   (ii) coupling said at least one resilient member along at least one edge of said opening, said at least one resilient member configured to be extendible along the depth of the mattress; and   (iii) sewing adjacent edges of said opening together.   
     
     
         6 . The method of  claim 5 , wherein said opening has a generally L-shaped edge. 
     
     
         7 . The method of  claim 5 , wherein said opening has a generally V-shaped edge. 
     
     
         8 . The method of  claim 5 , wherein the step of coupling comprises the step of sewing said at least one resilient member along at least one edge of said opening. 
     
     
         9 . The method of  claim 5 , wherein the step of coupling comprises the step of sewing said at least one resilient member along at least one edge of said opening, said at least one resilient member being encased in a protective sleeve or channel. 
     
     
         10 . The method of  claim 5 , wherein the step of coupling comprises the step of sewing a fabric attachment conforming generally to the shape of said opening thereon, said fabric attachment having at least one resilient member sewed along at least one edge of said fabric attachment. 
     
     
         11 . The method of  claim 5 , wherein the step of coupling comprises the step of sewing said at least one resilient member sandwiched between one or more layers of a fabric. 
     
     
         12 . The method of  claim 1 , wherein said at least one resilient member is disposed proximate to at least one other said resilient member such that each of said resilient members are sandwiched between one or more layers of a fabric to form at least one set of resilient members. 
     
     
         13 . A contour sheet comprising a mattress cover surface and a plurality of side surfaces, wherein at least a portion of the side surfaces is configured to be resilient and extendible along a depth of a mattress such that said contour sheet is releasably secured to the mattress. 
     
     
         14 . The contour sheet of  claim 13 , wherein at least a portion of the side surfaces is provided with at least one resilient member configured to be extendible along the depth of the mattress. 
     
     
         15 . The contour sheet of  claim 14 , wherein said at least one resilient member is further configured to be sandwiched between one or more layers of a fabric. 
     
     
         16 . The contour sheet of  claim 14 , wherein said at least one resilient member is attached along corners that conform with corners of the mattress. 
     
     
         17 . The contour sheet of  claim 14 , wherein said resilient members are provided in a spaced apart manner along the side surfaces. 
     
     
         18 . The contour sheet of  claim 13 , wherein at least a portion of the side surfaces is provided with sets of resilient members, each of said sets of resilient members comprising a plurality of resilient members configured to be extendible along the depth of the mattress. 
     
     
         19 . The contour sheet of  claim 18 , wherein each of said plurality of resilient members constituting said sets of resilient members is further configured to be sandwiched between one or more layers of fabric. 
     
     
         20 . The contour sheet of  claim 18 , wherein said sets of resilient members are attached along corners that conform with corners of the mattress. 
     
     
         21 . The contour sheet of  claim 18 , wherein said sets of resilient members are provided in a spaced apart manner along the side surfaces. 
     
     
         22 . The contour sheet of  claim 18 , wherein said sets of resilient members are configured to provide an elongation ratio of about 1:3 or more of the un-extended to extended length of the side surfaces along the depth of the mattress. 
     
     
         23 . The contour sheet of  claim 14 , wherein the at least one resilient member is attached in a vertical direction along the depth of the mattress or at an angle relative to the vertical direction.
