Description

[Detailed explanation of the idea]

(Field of Industrial Application) This invention relates to a futon that can be used alone or in combination with other bedding. (Prior Art) Bedridden elderly and sick people cannot easily change their sleeping position, so pressure is applied to specific parts of their bodies for a long period of time, which impairs blood circulation and makes them prone to bedsores. In most households with a bedridden patient, the patient is placed on an ordinary Japanese futon, and even if the patient's body position is changed from time to time, the occurrence of bedsores cannot be prevented. As bedding to prevent bedsores,
A so-called air mat is common, and in this mat, a large number of air layers are formed with plastic film, and these air layers are appropriately divided into two sets, and compressed air is sent and discharged alternately every few minutes. The part of the layer from which the compressed air has been expelled is concave, improving blood circulation, while the part of the layer that has air in it swells, creating a pine surge effect. Although this air mat is effective in preventing bedsores in patients, it is extremely expensive and is therefore difficult to be used in homes, let alone in hospitals. In addition, relatively inexpensive bedding for preventing bedsores is the pressure-free pine tress (trade name: Asepas pine tress), which has an upper layer of polyurethane foam with corrugated sides for improved cushioning, or the sheet made of coconut fibers made by needle punching. There are palm pierced pine tresses. Furthermore, for example, Utility Model Publication No. 49-31923 relates to a futon that prevents the body from sinking too much and has excellent breathability, in which a fine denier thermoplastic synthetic fiber is located in the center against a thick denier rayon fiber on the outside.
The entire structure is intertwined by needle punching. (Problem that the invention aims to solve) Even if it is a relatively inexpensive pine tress, the pressureless pine tress has almost no moisture absorption or moisture release properties, so in hot summers it is recommended to use pads with a porous structure that have good hygroscopicity. It takes. On the other hand, palm pierced pine tresses have excellent breathability, but are hard overall, so it is desirable to layer an elastic pad on top of them, and care must be taken to keep them warm in the cold winter months. Similarly, Utility Model Publication No. 49-31923 is suitable for use by placing it on a soft urethane mattress, but is too hard to use alone and is not sufficiently durable. (Means for Solving the Problems) This invention was proposed to improve the above-mentioned problems with conventional pine braces for preventing pressure sores, and is relatively inexpensive and can be used alone. It is also intended to be used in conjunction with other bedding. Furthermore, the futon according to this invention is not only used to prevent bedsores of sick and elderly people, but also can be used by the general public to prevent the spine from bending during sleep so that they can sleep soundly, and can also be used as a healthy futon for infants. The mattress according to this invention is made of a mat material 1, as shown in FIG. 1, which has a three-layer structure comprising an upper soft layer 2, an intermediate board layer 3, and a lower cushion layer 4. The upper soft layer 2 is preferably made of a relatively soft material that has good contact feel and moisture absorption and moisture release properties, and examples thereof include cotton, felt, quilted fabric, and the like. When the soft layer 2 is felt, the felt generally has a density of 0.055 to
The compression rate is 0.07 g/cm ³ , the compression ratio is 18 to 25% (measured by method A of JiS L1021), and the thickness is, for example, 20 to 30 mm. This felt may be made of, for example, wool or polyester fiber, or it may be needle-punched after blending these fibers, and may be subjected to antibacterial treatment or deodorization treatment as desired. Further, when the cover cloth 5 is a relatively thick cloth, it can be used as a substitute for the soft layer. The intermediate board layer 3 is preferably made of a relatively hard material that maintains the sleeping position of the human body in an almost upright position, such as hard felt, plastic board, etc.
Examples include fiber board and particle board. If the board layer 3 is a hard felt, the felt generally has a density of 0.25 to 0.30 g/
cm ³ , the compression rate is close to 0, and the thickness is, for example, 1 to 2 mm. This felt may be made by mixing heat-fusible fibers with ordinary fibers and then heat-treating the mixture, or by impregnating it with an appropriate resin and curing it. The heat-fusible fibers to be blended are generally larger in amount than normal fibers, and include polyethylene fibers, polypropylene fibers, vinyl chloride/vinyl acetate copolymer fibers, undrawn polyester fibers, and polyester cores covered with low-melting polyester. Examples include conjugate fibers and polypropylene/polyethylene conjugate fibers. Lower cushion layer 4
It is preferable that the material is capable of maintaining a normal sleeping posture and dispersing bed pressure appropriately over the entire body, and examples thereof include felt, coil springs, rubber, and urethane foam. When the cushion layer 4 is felt, the felt generally has a density of 0.08 to 0.10.
g/cm ³ , a compression ratio of 10 to 20%, a compression elastic modulus of 85% or more (measured according to method A of JIS L1021), and a thickness of, for example, 10 to 20 mm. The felt may have a cord finish on the back side to increase breathability. The futon of this invention is generally used by enclosing it in a cover cloth 5 as shown in Fig. 2, but each layer 2 to 4 may be wrapped separately or integrated with an appropriate adhesive or needle punching. The entire body may then be encapsulated. In consideration of parts replacement and folding, the board layer 3 is
It is also possible to integrate only the cushion layer 4 or the soft layer 2 and encapsulate the other layer alone. Moreover, when the whole is integrated, it can be used simply by covering it with a sheet. (Function) The futon according to this invention sufficiently absorbs and releases the user's sweat to prevent dry skin due to the relatively soft upper soft layer 2 that has good contact feel and moisture absorption and moisture release properties. fiber. Generally, this futon is used by itself in the hot summer months by being spread on a wooden floor, bed floor, tatami mat, etc., and in the cold winter months it is preferable to use it in conjunction with a pine mattress, Japanese futon, urethane foam, zabuton, etc. Even if the lower urethane foam or Japanese futon is too soft or too hard when used together with other bedding, bed pressure is appropriately dispersed by the presence of the lower cushion layer 4. This bed pressure is the pressure when each part of the body comes into contact with the surface of the bedding, and when the bed pressure is high in a part, blood circulation in that part decreases, causing bedsores. In addition, with the futon of this invention, the presence of the board layer 3 reduces sinking, and the sleeping position is almost straight and the spine does not bend, so you can sleep soundly in a natural sleeping position and it is effective for recovering from fatigue.
You can easily turn over and change your sleeping position freely, which reduces sweating. (Examples) Example 1 In order to manufacture the mat material 1 having ^the structure shown in FIG. Blend of 50% 25 μm wool and 50% 13 denier polyester fiber, punch density
A thickness of 24 mm was determined by needle punching at 100 needles/ ^cm2 , and the compression ratio was 20%. Intermediate board layer 3 is made of a blend of 80% 4-denier heat-fusible fiber (product name Meltei, manufactured by Unitika) and 20% 3-denier polyester fiber.
Using 250g/ ^m2 felt, punch density 300 pieces/
Perform needle punching of cm ² . In addition, the lower cushion layer 4 is made of 50% 150 denier and 30% 150 denier, respectively.
Needle punching is performed at a punch density of 80 stitches/cm ² using a felt weighing 800 g/m ² that is a blend of 30% denier and 20% 15 denier polyester fibers. Next, the board layer 3 is placed on the cushion layer 4, and the two are further integrated by punching at 80 stitches/cm ² . This is heat treated at 170° C. for 5 minutes to harden the board layer 3. The cover cloth 5 illustrated in FIG. 2 is a rectangular bag divided into an upper part 6 and a lower part, and the lower part is further divided into three adjacent parts 7, 8, 9.
Fasteners 10 to 13 are attached to each portion 6 to 9, respectively. The soft layer 2 has a fastener 10
The integrated board layer 3 and cushion layer 4 are sealed in the upper part 6 by opening and closing, and the integrated board layer 3 and cushion layer 4 are cut into about 1/3 of the length of the soft layer 2 and then sealed in the lower parts 7 to 9, respectively.
Enclose in.

[Table] As is clear from Table 1, the mattress of this example disperses bed pressure more appropriately than other bedding types, and shows no signs of bedsores even after being bedridden for three months. Next, Table 2 shows the test results of the amount of sinking from the surface of the bedding while lying on the back.

【table】

[Table] Measuring instrument: Surveying instrument transit As is clear from Table 2, the futon of this example allows the user to sink in less than other bedding types, so the user's spine does not curve and it is easier to turn over in bed. It's easy and you can sleep soundly. Example 2 The lower cushion layer 15 in FIG. 3 is made of the felt of blended polyester fiber used in Example 1,
After the needle punching described above, cord finishing is further performed by punching with a fork needle at a density of 40 needles/cm ² . As a result, the back surface of the cushion layer 15 becomes a cord surface with a corrugated side surface as shown in the figure. Next, the board layer 3 is layered on the cushion layer 15 and integrated by needle punching with a punch density of 80 stitches/cm ² . A dry amount of acrylic resin (trade name Polysol M-17) is applied to the back side of the cushion layer 15.
After applying 100 g/m ² and drying, heat treatment is performed at 170°C for 5 minutes. The futon using the board layer 3 and cushion layer 15 shown in FIG. 3 has much higher breathability than that of Example 1, and when laid directly on other bedding such as pine tresses or Japanese futons. This has the advantage that there is less misalignment. Example 3 The 50% polyester fiber blended in the upper soft layer 2 was pre-treated with antibacterial treatment (trade name: Biosil treatment)
Apply. As a result, it is possible to prevent the growth of mold and bacteria on the futon 14, effectively prevent bedsores on the user, and prevent dermatitis in infants. (Effects of the invention) The mattress according to this invention can be placed between the boards by itself after being enclosed in a cover cloth or directly covered with a sheet.
This invented futon can be used by laying it on bed floors, tatami mats, etc., or on top of pine mattresses, Japanese futons, urethane foam, sitting cushions, etc. Compared to conventional bedsore prevention mattresses, this futon can be used. To prevent bed sores by properly distributing the bed pressure of each part of the user over the whole body, and to maintain the sleeping posture in an almost straight-up state to prevent curvature of the spine. In addition, this invented futon is not only used to prevent bedsores for the sick and elderly, but also for the general public by maintaining a sleeping position and distributing bed pressure appropriately, and can also be used as a healthy futon for infants and young children. Can be used.
