DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The following is a detailed description of example embodiments of the invention depicted in the accompanying drawings. The example embodiments are presented in such detail as to clearly communicate the invention and are designed to make such embodiments obvious to a person of ordinary skill in the art. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention, as defined by the appended claims.

[0033] FIGS. 1-3 and 6 show one embodiment of a support pillow 10 of the invention. The support pillow comprises a pillowcase 20 having a first sleeve 30 for receiving a conventional pillow-fill unit 32 and a second sleeve 40 for receiving the cervical or neck support unit 42. The pillowcase 20 is preferably 31 inches long and 19 inches wide, where the first sleeve 30 is 11 inches wide the second sleeve is 7 inches long.

[0034] FIGS. 2 and 3 depict the pillow unit 32 and the neck support unit 42. The neck support unit 42 preferably comprises an inflatable air bladder 50 that is 5 inches in diameter, and is enveloped by a padding or cushion layer 52. The padding or cushion layer 52 is at least -inch-thick, and preferably inches thick. While the padding or cushion layer 52 is depicted as being formed on an inner surface of the second sleeve 40, the padding or cushion layer 52 also could be arranged about the outer surface of the cervical or neck support unit 42.

[0035] While first sleeve 30 may be a closed ended sleeve open at one distal end and closed at the opposite proximal end, FIG. 2 shows that first sleeve 30 may be optionally open on both opposite ends to accommodate different sized pillows 32 therein. Therefore a pillow 32 larger than first sleeve 30 will extend outward through the opposite open end of first pillow sleeve 30.

[0036] As shown in FIG. 2 the padding 52 on the inner sleeve surface of the second sleeve 40 is preferably resilient. Most preferably, the resilient padding 52 is made of a loft recovering material. Alternatively, the padding on the inner sleeve surface of the second sleeve can be formed with a visco-elastic foam (VEF), an elastomeric material, or pillow fill material such as feather down, wool, cotton or synthetic fabric materials in layers or particulates, such as rayon polyester, gel fibers, or polyurethane or blends thereof in combination. The padding requires a fill power to retain loftness in resuming padding height. The preferred pillow fill material defines a thickness of the inner sleeve, as between inch and 2 inches.

[0037] The inflatable air bladder 50 is shown in detail in FIG. 2, including a tube 54, which is a maximum of 6 inches, but which is not limited in shorter lengths. The tube cannot exceed six inches in length pursuant to safety standards for preventing choking of infants and small children. The inflatable air bladder is preferably made of an inflatable, stretchable material, such as, for example natural rubber sold under the brand name NEOPRENE. The inflatable air bladder is preferably covered with a soft expandable fabric, such as nylon. Preferably, the inflatable air bladder 50 includes a valve 56 that allows air to be input to the inflatable air bladder 50, to increase its size and internal air pressure, or allow air to be released from the inflatable air bladder 50, to decrease its size and internal air pressure. In one form, the valve allows for a user to use their mouth to increase the internal pressure and in another form the valve includes a squeeze ball or bulb 58 to add or extract air.

[0038] FIGS. 4 and 5 show use of the pillow 10 for supporting other body parts besides the neck, such as the knees or lumbar spine, by rotating the pillowcase 20 so that the padded sleeve 40 with the air bladder 42 is not at the side edge, but rather elevated in the middle.

[0039] FIGS. 7 and 8 show an alternate embodiment where instead of the pillow being inserted in a first sleeve of a pillowcase, the pillow 110 itself has an integral second padded sleeve 140 for supporting the air bladder 142 therein.

[0040] FIG. 9 shows an air bladder sleeve 240 attached to a climate controlled pillow 210 with warm and cool sections, 211 and 212, where optionally the air bladder 140 is shown segmented into segments 241.

[0041] Preferably, as shown in the alternate embodiment of FIG. 10, the valve, including the tube 54 and the squeeze ball 58, are stored after use in the second sleeve 40, during non-use.

[0042] Optionally, in alternate embodiment, the valve, including the tube 54 and the squeeze ball 58, are maintained inside the second sleeve 40 during both use and non-use and wherein to add air, the user either reaches in to squeeze the squeeze ball 58 or alternatively applies a pushing force against a part of an outer surface of the second sleeve 40 directly under which is the squeeze ball 58.

[0043] As shown in FIG. 11, the pillowcase 210 and associated sleeve 220 are opened at both side ends, so that larger different sized pillows 232 can be inserted within hollow sleeve 230, where the extra side length of the inserted pillow 232 (such as a King size pillow) can extend out the opposite side of the pillowcase 220, from which it was inserted. FIG. 11 also shows inflatable neck support unit 242 inserted within smaller hollow sleeve 240.

[0044] In an optional embodiment shown in FIGS. 12, 12A and 12B, a pillowcase 320 with a first double open ended sleeve 330 is provided for insertion of a pillow 332 therein, with one or more optional foam padding layers 361, 362, 363, etc., added to increase the thickness and rigidity or softness of the main pillow portion 332. For example, while not being limited any particular dimensions, layer 361 is shown as having a thickness of one quarter inch, layer 362 is shown as having a thickness of one half inch and layer 363 is shown as having a thickness of three quarters of an inch. Typically, as shown in FIG. 12B, the pillow 332 can be used with a single selected foam padding layer 362 of the plurality of optional foam padding layers 361, 362 and 363. However, as shown in FIG. 12A, the user can select a plurality of two or more foam layers from the group consisting of layers 361, 362, 363, etc.

[0045] The reason for increasing or decreasing rigidity or softness is because persons with cervical injuries may benefit from the inflatable bladder sleeve 342 against the nape of the neck, but the person may have pain in the back of the head, above the nape of the cervical neck, where the base of the skull meets the top of the neck, and may need to increase the rigidity of softness of the main pillow, beyond where the inflatable air bladder 342 meets the nape of the cervical neck.

[0046] Optional padding layers 361, 32 and/or 363 can be formed with a visco-elastic foam (VEF), an elastomeric material, gel, or polyurethane or blends thereof in combination. The padding layers 361, 32 and/or 363 also require a fill power to retain loftness in resuming padding height.

[0047] FIG. 12 also shows the support pillow 310 including a pillow case 320 having a first sleeve 330 for receiving a conventional pillow-fill unit 332 and a second sleeve 340 for receiving the cervical or neck support unit 342. FIG. 12 also depicts that the neck support unit 342 preferably comprises an inflatable air bladder 350 and is enveloped by a padding or cushion layer 352. The padding or cushion layer 352 is also at least -inch-thick, and preferably inches thick. While first sleeve 330 may be a closed ended sleeve open at one distal end and closed at the opposite proximal end, FIG. 12 further shows that first sleeve 330 may be optionally open on both opposite ends to accommodate different sized pillows 332 therein. Therefore a pillow 332 larger than first sleeve 330 will extend outward through the opposite open end of first pillow sleeve 330, such as shown in FIG. 11 herein.

[0048] As also shown in FIG. 12 the padding 352 on the inner sleeve surface of the second sleeve 340 is preferably resilient, such as, for example, the resilient padding 352 is made of a loft recovering material. Alternatively, the padding on the inner sleeve surface of the second sleeve can be formed with a visco-elastic foam (VEF), an elastomeric material, or pillow fill material such as feather down, wool, cotton or synthetic fabric materials in layers or particulates, such as rayon polyester, gel fibers, or polyurethane or blends thereof in combination. The padding requires a fill power to retain loftness in resuming padding height. The preferred pillow fill material defines a thickness of the inner sleeve as between inch and 2 inches. Preferably, the inflatable air bladder 350 includes a valve 356 that allows air to be input to the inflatable air bladder 350, to increase its size and internal air pressure, or to allow air to be released from the inflatable air bladder 350, to decrease its size and internal air pressure. In one form, the valve allows for a user to use their mouth to increase the internal pressure and in another form, the valve includes a squeeze ball or bulb 358 to add or extract air.

[0049] As will be evident to persons skilled in the art, the foregoing detailed description and figures are presented as examples of the invention, and that variations are contemplated that do not depart from the fair scope of the teachings and descriptions set forth in this disclostire. The foregoing is not intended to limit what has been invented, except to the extent that the following claims so limit that.
