DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) Referring to FIG. 1, a pillow 10 may be understood with respect to a horizontal direction 12a, longitudinal direction 12b, and a vertical direction 12c that are all mutually perpendicular to one another. The directions 12a, 12b, 12c are recited to facilitate understanding of relative positions of features of the pillow 10 but do not need to correspond to the actual orientation of the pillow 10 during use.

(12) The pillow 10 when in the illustrated sleeping configuration has a generally rectangular shape, or a bounding rectangle 12d may be defined in a plane parallel to the horizontal direction 12a and longitudinal direction 12b direction 12a, the bounding rectangle 12d being a smallest rectangle containing the pillow 10 with the pillow 10 resting on a support surface parallel to the plane and undeformed by any external force other than gravity. The horizontal direction 12a may be defined as parallel to the longest edges of the bounding rectangle, the longitudinal direction may be defined as parallel to the shortest edges of the bounding rectangle 12d (or edges other than those used to define the horizontal direction 12a where the bounding rectangle is a square). The vertical direction 12c is perpendicular to the directions 12a, 12b and corresponds to the amount of loft of the pillow 10.

(13) As is apparent in FIG. 1, the pillow may have a non-rectangular shape, including such non-angular features as rounded corners or narrowing toward the center of the pillow. In other embodiments, the pillow has a conventional rectangular shape. The shape shown in FIG. 1 may be the shape of the pillow containing filling. The filling may include cushioning material such as one or more sheets of foam (e.g., polyurethane or latex foam), shredded foam, polyester fibers (FIBERFILL), down feathers, or other cushioning material.

(14) FIG. 1 illustrates the sleeping case 14 of the pillow 10. The reverse of the pillow 10 (facing away from the viewer) may have the same shape and configuration and also form part of the sleeping case 14. The sleeping case 14 may be made of a natural or synthetic fiber such as nylon, polyester, cotton, linen, or other material known in the art for use in making pillow cases. In an exemplary embodiment, the sleeping case 14 is made of a stretchy woven nylon material.

(15) Referring to FIG. 2, while still referring to FIG. 1, a portion of the perimeter of the sleeping case 14 may define an opening 16. In the illustrated embodiment, this portion is a portion of the edge of the sleeping case 14 closest to the left edge of the bounding rectangle 12d in FIG. 1 and parts of the top and bottom edges extending away from the left edge, e.g., extending from the left edge between 40 and 60 percent of the length of the top and bottom edges. Stated differently, the perimeter of the sleeping case 14 defining the opening 16 may be positioned completely to one side of line 12e intersecting the pillow and parallel to the longitudinal direction 12b. This line 12e may be at the midpoint of the pillow 10 or rectangle 12d along the horizontal direction 12a or offset therefrom by up to 10 percent of the length of the pillow 10 or rectangle 12d along the horizontal direction 12a. In the illustrated embodiment, the line 12e is offset from the left edge of the pillow 10 or the bounding rectangle 12d along the horizontal direction 12a by an amount less than or equal to the length of the pillow 10 or bounding rectangle 12d in the horizontal direction 12a.

(16) The opening 16 may have a zipper 18 fastened around its perimeter and a zipper pull 20 for closing the zipper 18 and the opening 16. The pillow 10 may have the configuration of FIG. 1 when the zipper 18 and opening 16 are closed. When the zipper pull 20 is used to open the zipper 18, a storage case 22 is exposed. In this and other instances described herein where zippers are recited securing edges of material to one another, other closure mechanisms may be used instead, such as a series of snaps, magnets, buttons, hook-and-loop fasteners, or other closure mechanisms disposed along the edges being secured together.

(17) The storage case 22 may be made of a material that is some or all of more durable, less stretchy, and less flexible than the material forming the sleeping case 14. For example, the storage case 22 may be made of a non-stretchy woven nylon, which may be coated with polyurethane or other material to improve durability.

(18) As is apparent in FIG. 2, with the opening 16 opened, the pillow 10 is Y-shaped. For example, nodes 24 may be defined at the ends of the opening 16 where the zipper pull 20 is located when the zipper 18 is either completely open or completely closed. Lobes 26a, 26b, and 26c may extend outwardly from these nodes 24. As is apparent, outward facing surfaces of the lobes 26a, 26b are covered with the sleeping case 14. Surfaces of the lobs 26a, 26b facing inwardly toward one another are covered with the storage case. Both surfaces of the lube 26c are covered with the sleeping case 14. Both lobes 26a, 26b may include filling material in some embodiments. In other embodiments, only one lobe 26a or 26b contains filling material.

(19) Stated differently, the sleeping case is split between the top edge (left edge in FIG. 1), the split extending partially toward the bottom edge (right edge in FIG. 1). The inner surface of the split is formed by the storage case 22.

(20) Referring to FIG. 3, for placement in a storage configuration, the lobes 26a, 26b are folded down over the lobe 26c such that the storage case 22 is facing outwardly. The surfaces of lobes 26a, 26b that are covered with the sleeping case 14 may be facing and contacting surfaces of the lube 26c covered with the sleeping case 14. Regardless of the position of the lobes, 26a, 26b, 26c, the filling of the pillow and the sleeping case 14 are placed such that they are enveloped by and contained within the storage case 22. The storage case 22 is preferably constructed of a more durable, stain, and water-resistant material that protects the pillow with the softer, more comfortable material of the sleeping case 14.

(21) Referring to FIG. 4, the zipper pull 20 may then be used to close the opening 16 such that the zipper 18 and storage case 22 completely cover the pillow 10.

(22) Referring to FIG. 5, the storage case 22 may be made of a single sheet of material with the zipper 18 secured to portions of the edges of that sheet of material. The storage case 22 may be made of multiple pieces of material to form a pouch. A handle 30 may be secured to the storage case 22 to facilitate carrying of the pillow 10 when stowed.

(23) Referring to FIG. 6A, some embodiments, loose filling material is simply contained within the storage case 22 and sleeping case 14. In other embodiments, an inner pillow case 30 may be used and contain the filling material. The inner pillow case 30 may also be Y-shaped with nodes 32 on either side and lobes 34a, 34b, 34c extending outwardly from the nodes 32 and fitting inside the nodes 26a, 26b, 26c as defined above. The side of the inner case 30 facing away from the viewer may have a mirrored configuration and define one of the nodes 32.

(24) The inner case 30 may be of three-piece construction including a top piece 30a, bottom piece 30b, and inner piece 30c. The inner piece 30c is secured to the top piece 30a by seam 36a and to the bottom piece 30b by seam 36b. As is apparent, the seams 36a, 36b may extend substantially (e.g., within 3 mm) to the nodes 32. A right end portion of the top and bottom piece 30a, 30b are secured to one another by seam 36c substantially (e.g., within 3 mm) to the nodes 32.

(25) The inner piece 30c is described as being a single piece but may also include two pieces, such as connected by a seam extending between the nodes 32. The nodes 34a, 34b are therefore defined by the top piece 30a, 30b and the inner piece 30c whereas the node 34c is defined by the top piece 30a and the bottom piece 30b.

(26) The three-piece construction shown in FIG. 6A may also be used for constructing the sleeping case 14 and storage case 22, with the sleeping case 14 corresponding to the top piece 30a and bottom piece 30b and the storage case 22 corresponding to the inner piece 30c.

(27) Access to the interior of the inner case 30 may be by means of a zipper along any of the seams 36a, 36b, 36c. For example, a zippered opening 40 may be placed along the seam 30a at the end of the lobe 34a. In a like manner, the inner case 30 may be inserted into the sleeping case 14 by means of a zippered opening 42 defined by the sleeping case 14, such as opposite the opening 16.

(28) Referring to FIG. 6B, in some embodiments, a zippered opening 42a and corresponding zipper pull 42b are secured to the storage case 22. The inner case 30 may be inserted through this opening. However, when the pillow 10 is in a sleeping configuration (see FIG. 1), the inner case 30, zippered opening 42a, and zipper pull 42b are enclosed within the sleeping case thereby eliminating any discomfort that may be caused by the roughness of the zippered opening 42a and zipper pull 42b.

(29) Referring to FIG. 7, In some embodiments, the filling for the pillow 10 may be partially or completely embodied by an air bladder 44. For example, the air bladder 44 may be used in combination with another type of filing material such as down, a single piece of foam, or pieces of shredded foam. The air bladder 44 may include fused portions 46 inward from the perimeter thereof to decrease the height of the air bladder 44 when inflated. The air bladder 44 may include a valve 48 for inflating and deflating the air bladder.

(30) Referring to FIG. 8, in some embodiments, the storage case 22 defines an opening 50 through which the valve 48 is accessible. In his manner, when the sleeping case 14 is facing outwardly and the opening 16 is closed, the valve 48 and opening 50 will be inside the pillow 10.

(31) While the preferred embodiments 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. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiments. Instead, the invention should be determined entirely by reference to the claims that follow.
