Blanket/sheet lifting device and method

Abstract

A blanket/sheet lifter comprising a small resilient foam cushion blanket/sheet support having a flat bottom, an upwardly extending back, vertically extending sides, a front face and a top. The cushion is tall enough to accommodate the length of a user's foot, and is wide enough, such that it does not tip over readily to either side, and yet does not take up too much space on either side or below of a user's foot or feet. The bottom insufficiently long that the blanket/sheet lifter supports blankets/sheets above a person's knee, and the bottom provides a firm base such that it does not tip over front to back or back to front when positioned on its bottom; a cover for said cushion which includes pockets on the front face and sides for holding hot/cold packs. In use, the cushion rests on either its flat bottom surface or its flat back surface, depending on whether it is to be positioned adjacent the user's foot or knee.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) In the preferred embodiment, blanket/sheet lifter 1 includes an inner resilient but structurally firm cushion 10, covered by a soft covering 20 shaped to fit cushion snugly. (FIGS. 1-2) Cover 20 includes a corner zipper 21 which facilitates removal, cleaning and replacement of cover 20 on cushion 10. Cushion 10 defines the shape of blanket/sheet lifter 1, which has a flat bottom 11, a flat upwardly extending back 12, flat vertically extending sides 13, a flat top surface 14 which is shorter back to front than the bottom surface 11, a flat, vertically extending short front face 15 which is shorter than back 12, and upwardly and rearwardly sloping front face 16 extending from the top of the short front face 15 to the front edge of top surface 14.

(14) The terms flat and vertical as used throughout are used in a relative or general sense, rather than as precise terms. It will be apparent to those skilled in the art that some variation from a precisely vertical or precisely flat surface are possible without departing from the spirit and function of the invention. Similarly, directional terms such as front, back, top and bottom are relative terms based on the orientation of lifter 1 as shown in the drawings.

(15) Lifter 1, and correspondingly cushion 10, is tall enough to lift the blankets/sheets above the length of the average user's foot. Larger custom sizes are available. Side to side, the cushion 10, including bottom surface 11 wide enough, such that it does not tip over readily to either side, and yet does not take up too much lateral space on either side of a user's foot or feet. Front to back, the bottom surface 11 is sufficiently long that blanket/sheet lifter 1 supports blankets/sheets above a person's knee (FIG. 11), and bottom 11 provides a firm base such that it has fore and aft stability, and does not tip over when positioned on its bottom surface.

(16) Preferable dimensions for blanket/sheet lifter 1 are:

(17) Height from bottom 11 to top 14: 10-15 inches

(18) Width from side 13 to side 13: 5-10 inches

(19) Bottom surface front to back: 7-10 inches

(20) Top surface front to back: 3-5 inches

(21) Short front face, top to bottom: 3-5 inches

(22) Sloping front face: 6-12 inches

(23) The foam material of which cushion 10 is made is sufficiently resilient and firm so as not to deform under the weight of the blankets/sheets to the point of easily tipping over in use. Variations of foam products may be used in medical/hospital applications, e.g. medical grade, closed cell or open cell foam. Medium to firm foams can be used. Foams which show an indentation load deflection rating of from 31 to 50 lbs/50 square inches are preferred, and 42-50 is most preferred. This is the pressure in pounds per a 50 square inch area required to indent the foam 25% of its height, done on a four inch thick specimen. A preferred density for foams is from 1.30 to 1.85 pounds per cubic foot, with a density of 1.4-1.5 pounds per cubic foot being more preferred.

(24) Cover 20 for foam cushion 10 is preferably made of a soft material, and is preferably washable. A soft fleece is preferred. It is preferably anti-piling. The cover 20 must feel comforting to the user to the extent the user touches it. It includes an invisible zipper 21, preferably located on the rear corner, where back 12 and a side 13 meet, and preferably extending the full height of cover lifter 1. This facilitates removal and replacement of cover 20, for washing or the like.

(25) In the alternative embodiment blanket/sheet lifter 1A (FIG. 6), cover 20 includes a front pocket 22 and side pockets 23. Hot/Cold packs can be inserted into pockets 22 and/or 23 to apply heat or cold to an injury or reduce swelling as needed. Additionally this allows for temperature adjustments in the area immediately surrounding or touching the lifters, for hot summer or cold winter nights.

(26) In use, blanket/sheet lifter 1 or 1A rests on either its flat bottom 11 or its flat back 12, depending on whether it is to be positioned on a user's resting surface adjacent the user's foot (FIG. 7) or knee (FIGS. 10 and 11). When positioned adjacent a user's foot, the sloping front face is oriented to face the head of the bed. Preferably, one places one of the blankets/sheet lifters on the outside of the user's feet (FIG. 7), or on either side of one or both knees (FIG. 11), when being used to protect a knee. Alternatively, a single lifter 1 can be placed between the user's feet, which provides a tent like space to either side of the lifter 1 (FIG. 12). In an alternative use, blanket/sheet lifters 1 or 1A are dimensioned to provide elevated leg support at the user's knee, as in FIG. 10. A single lifter 1 or 1A is positioned on its back surface 12, with short front face 15 located under the knee, and sloping face 16 under the calf.

(27) The short front face 15 and sloping front wall 16 also make it comfortable for a user to rest the sole of his or her foot against face 15, either vertically as in FIG. 8, or horizontally as in FIG. 9. This allows for stretching of the plantar-fascia and heating or icing an injury when front pocket 22, and/or side pockets 23, is/are filled with a hot/cold packs.

(28) Blanket/sheet lifters in accordance with the invention, including without limitation the preferred embodiment disclosed, can be used to prevent painful contact between the blankets/sheets and the feet, toes, knees or other body parts, where the user may have, for example: a. Fibromyalgia b. Peripheral Neuropathy c. Plantar Fasciitis d. Diabetes Pain e. Arthritis/Osteoarthritis f. Shingles Pain g. Foot Ulcers h. Gout i. Restless Leg Syndrome j. Broken or Sprained Toe/Foot/Ankle k. In-grown Toe Nails l. Blisters
This is sampling and by no means a comprehensive list of applicable ailments that may benefit from the use of these lifters.

(29) The use of blanket/sheet lifters of the present invention relieves the pressure/pain of bedding on surgical wounds. They can be used as elevation pad for foot, knee or hands. Pockets 22 and 23 in embodiment lifter 1A make it desirable to use the invention with hot/cold packs for relief of pain and swelling as well as for use in hot or cold weather, to condition the air in the vicinity of the feet, or other body parts.

(30) Additionally placing the lifters on the outside of either foot will allow your foot to lean gently against them, preventing your feet from being pushed down and to the side twisting your ankles and knees in an uncomfortable and potentially painful position. Creating a space for your feet without the pressure of the blankets/sheets allows for the natural position of your foot, thereby allowing your plantar fascia to avoid shrinking and tightening overnight. An injury or wound is not a necessary requirement to find the comfort and enjoyment of the lifting device, a comfortable night's sleep for anyone will be achieved with its use.

(31) Of course, it is understood that the forgoing are preferred embodiments, and that changes and alterations as well as additional beneficial uses can be made which are encompassed within the spirit and scope of the present invention.
