Definitions

  • the present invention relates to beds, bed sheets and waterproof bed clothing.
  • Mattress covers, sheets, or pads are widely used to cover mattresses. Covers, sheets, and pads come in a variety of styles and are used for several different purposes. Some offer extra cushioning and support to a sleeper, while others act as an extra layer, keeping the mattress itself cleaner.
  • SIDS sudden infant death syndrome
  • SIDS is the leading cause of death in the United States for babies between one month and one year old. SIDS is not any one illness or disease. Rather, it is the diagnosis given when a child under a year old dies suddenly and an exact cause cannot be found after a death scene investigation, an autopsy, and a review of the child's medical history are all undertaken. That SIDS can happen without warning makes it a particular source of insecurity for parents.
  • SIDS most commonly affects babies between the ages of one and four months, and ninety percent (90%) of cases involve infants younger than six months.
  • a bedding element pad, mattress, top sheet, bed cover, etc.
  • a thick or loose fitted cover, sheet, and/or pad may interfere with the breathing of a baby, especially if a baby's face presses against or is near these items. It is therefore imperative that the pad or mattress fits properly in the crib. Any gaps or holes could pose a danger to a baby because airflow near and around the baby's head may be reduced.
  • the crib pad or mattress should also be firm.
  • a soft mattress can conform to the shape of a baby's head or face, increasing the risk of suffocation. It is also important that there is no loose bedding or any objects that could increase the risk of entrapment, suffocation, or strangulation within the bed.
  • Pressure ulcers also known as bedsores
  • bedsores are a common skin condition that occurs when a person is unable to redistribute the pressure on their body.
  • Bedsores are particularly common in geriatric patients and are particularly problematic for the elderly, as the healing of bedsores is slowed by increased age of the person.
  • bedsores can be difficult to prevent, especially in frail elderly individuals and people confined to wheelchairs.
  • the primary cause of bedsores is prolonged pressure on a localized area of the body, bedsores can also be caused by a combination of pressure and friction. For this reason, tightly fitted sheets for a person with restricted mobility are crucial to the prevention of bedsores.
  • Another consideration is that the aged or disabled person lacking mobility may want to change their own bedding but requires a design that is easy for them to do so.
  • the present invention provides systems relating to a safe, easily removable and reusable sheet and pad system that attaches to a mattress.
  • the detachable pad of the present invention provides a tightly fitted pad to reduce friction that can be caused by loose sheets and bedding.
  • the pad can be changed, cleaned, and replaced frequently.
  • the pad is a waterproof pad that covers only the portion of the mattress that is in closest proximity to the pelvis and buttocks area of a user. This allows the user to remove the pad from one fitted sheet and attach it, optionally in a different orientation, to a different sized fitted sheet. In this way, a user can use the same pad for differently sized mattresses.
  • the invention disclosed herein allows a user to remove bedding without having to regularly lift the mattress or manoeuvre the top sheets around the mattress corners. Therefore, this invention is particularly useful for the elderly and people with disabilities who may suffer from diminished manual dexterity.
  • the invention provides a detachable sheet system for use in a bed, the system comprising: a fitted sheet constructed and arranged to fasten around a mattress, the fitted sheet having a first top surface adjoining a second top surface of the mattress and a first bottom surface adjoining a second bottom surface of the mattress; a sheet pad constructed and arranged to cover a substantial portion of the second top surface of the mattress; and a first fastening means for operatively coupling the sheet pad to the fitted sheet.
  • the invention provides a detachable sheet system for the use in a bed, the system comprising: a fitted sheet constructed and arranged to fasten around a mattress, the fitted sheet having a first top surface adjoining a second top surface of the mattress and a first bottom surface adjoining a second bottom surface of the mattress, wherein the fitted sheet covers a substantial portion of the mattress; a waterproof pad constructed and arranged to cover a portion of the second top surface of the mattress, and having: a bottom waterproof layer, a middle absorbent layer, and a top fabric layer; a first fastening means for operatively coupling the waterproof pad to the fitted sheet; wherein the waterproof pad is substantially immovable along the mattress due to the first fastening means being mounted at the edge of a third bottom surface of the waterproof pad; and wherein the waterproof pad is positioned in close proximity to a buttocks and pelvic area of a user.

  • FIGS. 1 through 9 illustrate schematic representations of various embodiments of the present invention and will now be described in greater detail.
  • the present invention contemplates a sheet pad 120 designed to cover an entire or substantial portion of a mattress 100 .
  • the mattress 100 can optionally be supported by a bed frame (not shown), such as, for instance, a crib (not shown).
  • the mattress 100 is covered by a fitted sheet 110 .
  • the fitted sheet 110 can be designed to only cover the side portions and the edges of the top surface of the mattress 100 , as shown in FIG. 1 , or it can be designed to cover the entire top surface of the mattress 100 .
  • the fitted sheet 110 may be fastened to the mattress 100 through a variety of means, described in more detail below. Without limiting the foregoing, the fastening means to fasten the fitted sheet 110 to the mattress 100 may include means well known in the art, including an elastic band system that allows the bottom surface of the fitted sheet 110 to wrap around and hold to the bottom surface of the mattress 100 .
  • the fitted sheet 110 has a first fastening means 130 A, 130 B that fastens the sheet pad 120 to the fitted sheet 110 .
  • the first fastening means 130 A, 130 B could operate through a variety of mechanisms. For instance, a hook-and-loop fastening mechanism (such as VelcroTM) could be used.

  • the top and bottom portions of the first fastening means 130 A, 130 B cooperate to fasten the sheet pad 120 to the fitted sheet 110 , such that the sheet pad 120 does not move relative to the fitted sheet 110 . This aids in minimizing the friction caused by the moving of the sheet pad 120 when a person uses the detachable sheet system.
  • the bottom portion 130 A of the two-part fastening system is configured to be located at the perimeter of the mattress 100 on the top surface of the fitted sheet 110 .
  • the complementary top portion 130 B of the two-part fastening system covers the perimeter of the bottom surface of the sheet pad 120 such that the bottom portion 130 A of the two-part fastening system on the top surface of the fitted sheet 110 has a corresponding top portion 130 B on the bottom surface of the sheet pad 120 .
  • a hook and loop fastener means is used as the first fastening means 130 A, 130 B to couple the sheet pad 120 to the fitted sheet 110 .
  • the hook portion of the hook and loop fastener can be the bottom portion 130 A of the two-part fastening system, while the loop portion of the hook and loop fastener can be the top portion 130 B of the two-part fastening system.
  • the two-part fastening system 130 A, 130 B may use strips of hook and loop fasteners or a continuous strip of hook and loop fasteners at each edge of the mattress 100 , or some other configurations of fastening sections as would be readily understood by a skilled artisan.
  • hook-and-loop fastener provides a substantially immovable sleeping arrangement for a user and further provides an easy removal and replacement padding system.
  • any other alternative fastening means known in the art may be used to provide tautness and a snug fit between the sheet pad 120 and the fitted sheet 110 .
  • Alternative fastening means may include a zipper device, a knot system, or buttons.
  • the first fastening means 130 A, 130 B does not need to be limited to the edges of the fitted sheet 110 or the edges of the sheet pad 120 . Rather, the first fastening means 130 A, 130 B may cover the entire top surface of the fitted sheet 110 and the entire bottom surface of the sheet pad 120 . Such an implementation of the present invention would substantially increase the immovability of the sheet pad 120 when it is fastened to the fitted sheet 110 .
  • the first fastening means 130 A, 130 B is intentionally mounted at the edge of the sheet pad 120 and the fitted sheet 110 to construct a substantially immovable sheet pad 120 , and to prevent holes, gaps, or other openings.
  • the sheet pad 120 consists of a single padded layer and a fastening means.
  • the materials that can be used in the construction of the sheet pad include nylon, polyester, cotton, rayon, bamboo, viscose, linen, and silk.
  • the fitted sheet used in any embodiments of the present invention may be designed to be waterproof, such that the fitted sheet has a waterproof layer, similar to the waterproof pad described in FIG. 2 . More specifically, the fitted sheet may be made of a waterproof material. In that case, the sheet pad may not include a waterproof layer. For further clarity, the fitted sheet may include waterproof material such that the sheet pad does not require any waterproof material in its construction. Yet this alternative provides waterproofing.
  • FIG. 2 illustrates another embodiment of the present invention. This embodiment uses a waterproof pad 200 instead of the sheet pad 120 (shown in FIG. 1 ).
  • the mattress 100 is covered by a fitted sheet 240 .
  • the waterproof pad 200 is fastened to the fitted sheet 240 by a first fastening means 250 .
  • the first fastening means 250 can operate in the same manner as the first fastening means described in greater detail above with reference to FIG. 1 .

  • the waterproof pad 200 consists of three layers: a bottom waterproof layer 210 , a middle absorbent layer 220 , and a top fabric layer 230 . These layers may form a substantially unitary article.
  • the height and the texture of the waterproof pad 200 are important, as having a pad that is too thick or too soft, for example, may cause discomfort and irritation to the user. Therefore, the overall thickness of the waterproof pad 200 is, in one embodiment, approximately 6 mm. Further, the waterproof pad 200 may be purposely stitched in a specific pattern to ensure that the middle absorbent layer 220 stays evenly distributed at a constant height or thickness. These design features further reduce the mobility of the middle absorbent layer 220 . It will be apparent to a person skilled in the art that the stitched patterns could be a variety of patterns. For example, sewn or quilted patterns, such as loops, diamonds, and squares, may be used. Furthermore, continuous or non-continuous stitching patterns may be used.
  • the bottom waterproof layer 210 of the waterproof pad 200 protects the underlying mattress 100 and fitted sheet 240 from potential soiling.
  • the bottom waterproof layer 210 can be made of any type of water resistant or waterproof material.
  • the material used is a waterproof tent fabric, such as a mixture of polyester with plasticized polyvinyl chloride (PVC-P).
  • PVC-P plasticized polyvinyl chloride
  • Other materials that can be used include ethylene vinyl acetate (EVA), polyethylene vinyl acetate (PEVA) polyvinyl acetate (PVA), polyvinyl butyral (PVB).

  • the corner is not only unattached to the fitted sheet but has also been cut off. For best results, the unaffixed corner is adjacent a section where the waterproof pad is affixed to the fitted sheet.
  • a modified side edge 920 is also taught by the present invention to affix the waterproof pad 900 to the fitted sheet 930 adjacent the side edge of the mattress. This permits a user to slide off the bed along the modified side edge without encountering a ridge or bump that may form when the waterproof pad is attached at the edge of the mattress. For elderly or mobility-challengers users, this embodiment is very advantageous and reduces mobility impediments that may be created by a slight ridge when the pad is affixed to the fitted sheet along the top surface of the mattress.
  • the illustrated detachable sheet system is designed for use with a bed
  • the invention can also be used with sofas, chairs, seats, and pillows.
