`
`PRIORITY CLAIM
`
`This application claims priority to U.S. Provisional Patent
`Application Ser. No. 60/577,711 filed Jun. 7, 2004 and U.S.
`Provisional Patent Application Ser. No. 60/658,663 filed
`Mar. 3, 2005. Each and all of the foregoing applications are
`incorporated by reference as if fully set forth herein.
`
`FIELD OF THE INVENTION
`
`This invention relates to bedding material.
`
`BACKGROUND OF THE INVENTION
`
`Bedding material particularly sheets applied to beds are
`made of single composition fabrics. The single composition
`fabrics have only a specific type of heating characteristics to
`the bed occupants. The heating characteristics have a rate of
`heating that may be too rapid to one bed occupant to that of
`another. There is a need for bedding materials that provide
`differential warming characteristics or feeling of rate of
`warming to different bed occupants.
`
`SUMMARY OF THE INVENTION
`
`2
`
`between the cotton and polar fleece bi-sections. The slit in
`the middle of the flat top sheet permits flexibility for the bed
`occupants to move their arms or legs through the slit opening
`for cooling or other reasons.
`Another embodiment of the bi-sectional bedding material
`includes a bi-sectional flat or top sheet that is sewn to the
`fitted or bottom bi-sectional sheet. Each fitted, flat, bottom,
`and top bi-sectional sheets have sections composed of
`different fabrics. For example, cotton and polar fleece. The
`combination of stitched flat and fitted bi-sectional sheets
`
`advantageously provide for a single bed-making operation.
`A particular embodiment of the toe-end stitched flat to fitted
`bi-sectional sheets includes the top sheet having a slit at the
`head-end of approximately 10% of the length of the top
`sheet, leaving approximately 90% of the top sheet being
`seam stitched thereby uniting the cotton and polar fleece
`fabric sections.
`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`Preferred and alternative embodiments of the present
`invention are described in detail below with reference to the
`
`following drawings.
`FIG. 1 is an isometric view of a bi-sectional flat sheet
`
`having head and toe slits adjacent to a bi-sectional fitted
`sheet;

`
`Preferred and particular embodiments include bi-sectional
`sheets that either fit to a bed mattress or are overlaid over the
`bed mattress wherein each section is made from a different
`
`having head and toe stitches adjacent to a bi-sectional fitted
`sheet;
`FIG. 3 is an isometric view of a bi-sectional flat sheet
`

`
`fabric having different warming characteristics. One particu-
`lar embodiment is a bottom or fitted bed sheet having at least
`two sections, one section having a fabric that is different
`from the other section’s fabric. In a particular embodiment
`of the fitted sheet, one section for example is cotton, the
`other section is polar fleece. In the fitted sheet embodiment,
`the cotton and polar fleece sections are sewn together in the
`middle of the bi-sectional bed sheet. Other particular
`embodiments of the fitted bed sheet include slits at the depth
`ends of the fitted sheet, particularly in the head-end and the
`toe-end. The slits at the head and toe-end of the fitted
`
`bi-sectional sheets provide a gap the spacing of which
`imparts greater flexibility for making or applying the fitted
`sheet to the mattress.
`
`Other embodiments of the multi-sectional bedding mate-
`rial
`is a top sheet similarly comprising a bi-sectional
`arrangement of different materials in each section. The top
`sheet overlays the fitted sheet and is separately applied to the
`mattress. Embodiments of the top sheet include different
`arrangements of slits advantageously placed to provide
`different use options to the bed occupants. In one particular
`embodiment of the top sheet, partial splits are placed at the
`head and toe-ends of the sheets to allow for improved
`flexibility in tucking in at the toe-end as well as to provide
`the head-end of the sheets may be independently folded as
`desired by the bed occupants. In a particular embodiment of
`the top sheet, the one section is cotton and the other section
`is polar fleece with a pillow or head-end slit of approxi-
`mately 10% the length of the top sheet and a comparable
`10% split at the toe-end of top sheet, leaving approximately
`80% of a sewn stitch uniting the cotton and polar fleece
`bi-sections.
`
`Another embodiment of the top sheet includes a middle
`slit and stitched ends. The stitched ends occupy approxi-
`mately 20% the length of the top sheet where 10% is stitched
`at the head-end of the top sheet and 10% stitched at the
`toe-end of the top sheet, leaving pillow 80% of an open slit

`
`DETAILED DESCRIPTION OF THE
`PREFERRED EMBODIMENT
`
`FIG. 1 is an isometric view of a hi-sectional flat sheet
`
`having head and toe slits adjacent to a bi-sectional fitted
`sheet. Also shown in FIG. 1 is a projected side view of the
`fitted sheet. FIG. 1 illustrates a fitted sheet/flat sheet com-
`
`bination 10 where each fitted and flat sheet are comprised of
`two fabric sections. As shown, the fitted sheet 11 comprises
`a cotton section 16 and a polar fleece section 18. Uniting the
`cotton section 16 and the polar fleece section 18 is a
`continuous stitch 14 that is continuous along the approxi-
`mate middle of the fitted sheet 11. The fitted sheet 11 is
`
`applied to the mattress bed. The combination bedding mate-
`rial 10 also includes a fiat sheet 12. The flat sheet 12
`
`similarly has a cotton 16A and a polar fleece 18A. The fabric
`bi-sections 16A and 16B are united together via a partial
`stitch 19A. The partial stitch 19A occupies approximately
`the middle 80% of the length of the flat sheet 12 and is
`approximately along the centerline of the flat sheet 12. On
`either side of the partial stitch 19A are partial splits 19B and
`19C. Partial split 19B is located along the pillow or head-end
`of the flat sheet 12 and partial split 19C is located at the
`toe-end of the flat sheet 12. Partial splits 19B and 19C are
`approximately 10% of the length of the flat sheet 12. The
`partial splits at each end of the sheet permit flexibility for the
`top sheet fabric bi-sections 16A and 18A to be independently
`folded over at the pillow end and further provides flexibility
`for tucking in under the mattress at the toe-end of the flat
`sheet 12.

`FIG. 2 is an isometric and side View of a bedding material
`system 20. The bedding material system 20 includes the
`fitted sheet 11 as previously described from FIG. 1 and a flat
`sheet 22. The flat sheet 22 includes a cotton fabric section
`
`16B and the polar fleece section 18B. Along the center line
`of the flat sheet 22 is a series of partial stitches and a partial
`split. Disposed approximately along the middle 80% section
`of the centerline of the flat sheet 22 is a partial split 29A.
`Bracketing either side of the partial split 29A are partial
`stitches 29B and 29C. The partial stitches 29B and 29C are
`approximately 10% of the flat sheet length. Partial stitch 29B
`is located at the head-end of the flat sheet 22 and partial
`stitch 29C is located at the toe-end of the flat sheet 22. The
`
`10
`
`partial stitches 29B and 29C at each end of the flat 22
`maintains the attachment of the cotton bi-section 16B and
`
`15
`
`the polar fleece bi-section 18B. The partial split 29A located
`in the approximate middle 80% of the flat sheet 22 provides
`flexibility to the bed occupants to extend appendages
`through or to receive medical devices.
`FIG. 3 is an isometric and side view of a bedding system
`30. The bedding system 30 includes a flat sheet 12 as
`previously described from FIG. 1 and a fitted bottom sheet
`31. The fitted bottom sheet 31 includes a cotton fabric
`
`bi-section 16C and a polar fleece fabric bi-section 18C
`which are seamed together via a partial stitch 34 along the
`middle approximate 80% of the center line via a partial stitch
`34. Located on each side of the partial stitch 34, are partial
`splits 36A and 36B. Partial splits 36A is located at the
`toe-end of the mattress and partial split 36B is located at the
`head-end of the mattress of the fitted sheet 31. The partial
`splits at each end of the fitted sheet 31 provide flexibility for
`tucking the flat sheet or otherwise fitting the flat sheet around
`the mattress.
`
`FIG. 4 is an isometric view of a bedding system 40. The
`bedding system 40 includes a bi-sectional
`flat sheet 44
`stitched to at the toe-end of a fitted sheet 11. Alternatively,
`the bi-sectional flat sheet 44 may be stitched the toe-end of
`a fitted sheet 31. The bi-sectional flat sheet 44 includes
`
`cotton fabric bi-section 16D and polar fleece fabric bi-
`section 18D, each bi-section being seamed together via a
`continuous stitch 46 that runs the length of the flat bi-section
`sheet 44. The bedding system 40 advantageously provides
`for a single bed-making operation in that the bi-sectional flat
`sheet 44 is seamed to the fitted sheet 11 via a continuous
`
`stitch 48. Such an arrangement provides for a one bed-
`making operation to the mattress. Thus, the bedding system
`40 is polarized in a sense that, for example, the cotton
`section is on the left side of the bed and the polar fleece
`section is on the right side of the bed. Other embodiments
`would allow for the respective cotton and polar fleece fabric
`sections 16D and 18D to be switched so that the cotton
`
`section would be on the right side of the bed and the polar
`fleece section would be on the left side of the bed. Yet further
`embodiments would include the fitted sheet 11 to have the
`
`cotton bi-section 16D on the left, the polar fleece fabric
`section 18D on the right, and the bi-sectional top sheet 44
`having the polar fleece fabric section on the left, and the
`cotton fabric section 16D on the right. In the proceeding
`embodiment, this would mean that the cotton fabric section
`16D of the fitted sheet would be opposing the polar fleece
`fabric section 18D of the flat sheet 44. Similarly, in this
`switched around arrangement, the polar fleece fabric section
`18 of the fitted sheet 11 would be opposing the cotton fabric
`section 16D of the flat sheet 44.
`FIG. 5 is an isometric and cross-sectional view of a
`bi-sectional flat sheet stitched to the toe-end of a bi-sectional
`
`4
`a fitted sheet 11 as described in FIG. 1, and a flat sheet 54.
`Both the fitted sheet 11 and flat sheet 54 are bi-sectional in
`
`that they include a cotton fabric section 16E and a polar
`fleece section 18E. The fitted sheet 54 is similar to the fitted
`
`sheet 44 of FIG. 4 with the exception that the head or pillow
`end of the flat sheet 54 is a partial stitch 56A that seams
`together the cotton fabric section 16E and the polar fleece
`section 18E along approximately 90% of the length of the
`flat sheet 54. Adjacent to and at the head-end of the flat sheet
`54 is a partial slit or partial split 58B. The partial slit or
`partial split 58B serves the same purpose as the partial split
`19B of FIG. 1 in that it provides for independent folding
`over of the respective cotton fabric section 16E and polar
`fleece fabric sections 18E from one another. As shown in
`
`FIG. 5, the flat sheet 54 is seamed to the fitted sheet 11 by
`a continuous stitch 59. As with the bedding material system
`40, the bedding material system 50 advantageously provides
`for a single bed-making operation in that the flat and fitted
`sheets 54 and 11 are simultaneously applied to the mattress.
`As shown in FIG. 5, the bedding material system 50 results
`in a cotton section 16E being located on the left side of the
`bed and a polar fleece section on the right side of the bed.
`In this arrangement, bed occupants are cocooned in either a
`cotton-to-cotton opposing section or polar fleece-to-polar
`fleece opposing sections of the fitted and flat sheets 11 and
`54. As previously described for FIG. 4, the bedding system
`50 may be so configured that the polar fleece sections are on
`the left and the cotton sections are on the right. In addition,
`as described in FIG. 4, similarly for FIG. 5, there can be a
`hybrid combination in which the flat sheet 54 has the polar
`fleece section opposing the cotton section of fitted sheet 11
`and the cotton section of flat sheet 54 opposing the polar
`fleece section of fitted sheet 11.
`

`
`Other embodiments for the bedding systems 40 and 50
`also would allow for the stitching of the respective flat sheets
`44 or 54 to be stitched to other embodiments of the fitted
`
`sheet particularly fitted sheet 31. Yet other embodiments of
`the flat sheets 44 or 54 may be configured similarly to the flat
`sheet 22 wherein there is a partial slit as shown in 29A and
`a partial stitch at the head as shown in 29B.
`The embodiments as described in FIGS. 1—5 are applied
`to king size, queen size, and full size beds. The dimensions
`of a king size bed are approximately for the fitted sheet
`78"><80"><l8". For the flat sheet about l08"><l02" wherein
`
`78" are sewn, 24" are split roughly 12" on the head and 12"
`on the foot. For the dimensions of the queen size, the fitted
`sheet has an approximate dimension of 60"><80"><l8" and the
`flat sheet 90"><l02". For the flat sheet queen size 78" are
`sewn and 24" are split with 12" on the head and 12" on the
`foot. The dimensions for the full size are fitted sheet
`
`approximately 60"><80"><l 8" and for the flat sheet 88"><l02".
`For the flat sheet 78" are sewn, 24" are split with 12" of those
`being for the head and 12" for the foot. The preceding king,
`queen, and full sizes are applicable to the preceding FIG-
`URES.
`
`Dimensions that are more particular to the preceding
`embodiments are discussed below. The pillows are con-
`structed of two bi-sections, wherein one bi-section,
`for
`example cotton, is located on one side of the pillow, and the
`other bi-section, for example polar fleece, is located on the
`other side of the pillow.

`While the preferred embodiment of the invention has been
`illustrated and described, as noted above, many changes can
`be made without departing from the spirit and scope of the
`invention. For example,
`the flat and fitted sheets, either
`separately or in combination, may be applied to the mattress
`such that the orientation of the seam between the bi-sections
`
`of the sheets is approximately 90 degrees to the head and toe
`axis of the mattress. Each bi-section occupies approximately
`50% the mattress area, for example,
`the upper or head
`bi-section region is cotton, and the lower or toe-end bi-
`section region is polar fleece. Other percent area bi-sectional
`areas are possible, for example, the lower third bi-section is
`polar fleece, and the upper two-third bi-section is cotton.
`Alternate embodiments further include fabric bi-sections
`
`other than cotton and polar fleece. For example, bi-sections
`16 and 18 may respectively be made from silk and flannel
`fabrics. Accordingly, the scope of the invention is not limited
`by the disclosure of the preferred embodiment. Instead, the
`invention should be determined entirely by reference to the
`claims that follow.
