DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress containing charcoal having strip-shaped wrapped charcoal particles.

[0002]

[Prior Art] The far-infrared effect, deodorant, germ-proof and moisture-proof effect of charcoal such as Bincho charcoal, charcoal, and activated carbon have been well known and used for beddings such as mats, mattresses, pillows, and comforters. Have been. In conventional futons, finely ground charcoal was directly mixed into cotton. However, it is very difficult to uniformly mix the cotton and charcoal in the futon, and the charcoal's inherent deodorant, germicidal, moisture-proof, negative ion, electromagnetic wave prevention, purification, heat retention, and aging effects However, there is also a problem that the temperature decreases.

[0003] Bedding that has attempted to solve these problems is known in the art. The health futon disclosed in Japanese Utility Model Laid-Open No. 5-4996 is a sheet in which an outer cloth is coated on a sheet formed by arranging a large number of nonwoven bags filled with a carbon powder material. In this health futon, a single sheet material is used in which a carbon powder material is sealed in a nonwoven fabric bag, and the sealing edge of the nonwoven fabric bag is formed by heat sealing or the like. The sheet single bodies are arranged in a large number, connected and covered with an inner cloth, joined by means such as heat sealing through the inner cloth, and formed as a sheet (futon) as a whole.

[0004] In the above-described manner, the deodorizing, deodorizing, and air purifying effects of the carbon powder material are improved. In addition, since the carbon powder material is sealed in a non-woven bag, the carbon powder material is not easily removed. Since it does not scatter to the outside, external contamination can be avoided. In the health futon disclosed in the above publication, micronized pulverized charcoal is used. It is said that micronized pulverized charcoal is inferior in deodorizing effect and dehumidifying effect to powdered charcoal of about several millimeters. Further, precise work is required to arrange and connect a large number of individual sheet single bodies and join them to means such as heat sealing via an inner cloth.

[0005] In view of the problem described in Japanese Utility Model Application Laid-Open No. Hei 5-4966, which uses finely divided charcoal in units of microns, charcoal grains that do not pulverize can be encapsulated, and a charcoal containing powder that has been tried to be automatically encapsulated in a nonwoven bag by a machine. The mat is disclosed in
No. 22,681.

[0006] The charcoal-containing mat disclosed in Japanese Patent Application Laid-Open No. 8-322681 has a pair of outer layers formed by laminating a mat fabric, a cushioning material and a thin film layer, and quilting the whole, so as to face each other in one direction. Sewing is performed at regular intervals, and a band-shaped nonwoven bag enclosing charcoal grains is inserted into a rectangular space formed by the sewing.

In Japanese Patent Application Laid-Open No. 9-391,
A predetermined amount of charcoal granules, activated carbon granules, dried bamboo flakes, and other granules or flakes are placed in pockets formed at equal intervals in the longitudinal direction by heat-sealing the periphery of the two continuous-length band-shaped nonwoven fabrics. A band-shaped encapsulant sheet for bedding or the like enclosing an encapsulant is disclosed.

[0008]

Problems to be Solved by the Invention Japanese Patent Application Laid-Open No. 8-32268
The No. 1 charcoal-filled mat is suitable for a bed, but its heavy weight makes it a little inconvenient to use it on tatami mats or ondols that need to be stored. In addition, a sleeping person will sleep directly on a polypropylene sponge, but it is said that a soft cotton waist quilt is more suitable for elderly people with weak waist.

[0009] In particular, thick futons are said to hurt the lower back of the elderly, and therefore cannot sleep well and comfortably. Further, when laid on a tatami or ondol floor, a soft cotton futon having good hygroscopicity is preferred.

Therefore, the present invention uses a strip-shaped wrapped carbon particle instead of uniformly mixing the cotton and charcoal in the futon, and uses the deodorant, antibacterial, moisture-proof and negative ion effects inherent to charcoal. It is an object of the present invention to provide a cotton futon which is hard to break down by using a rigid polyurethane foam, while improving the effects of preventing, purifying, keeping warm and preventing aging of electromagnetic waves, and which is also gentle to the elderly.

[0011]

According to the present invention, in order to achieve the above object, an upper member and a lower member are overlapped with each other, and a peripheral edge thereof is sewn by a wrapping cloth. 1 non-woven fabric, cotton (cotton), rigid polyurethane foam, and a second non-woven fabric, having a plurality of seams formed by successively overlapping and sewing them in a stripe shape; A plurality of bag-shaped spaces defined by a plurality of parallel seams between the nonwoven fabric and a nonwoven fabric, and further, a band-shaped wrapping carbon granule inserted into each of the bag-shaped spaces; The member comprises a third non-woven fabric, cotton (cotton) and a lower fabric, which are sewn to the desired pattern throughout the quilting stitch, and the curled fabric integrates the upper member and the lower member. Wrapped around the periphery of the upper and lower members It is sewn together with them, and furthermore, the packed carbon granules are formed into a cylindrical shape so as to extend long with a flexible material, and the charcoal granules are stored in a plurality of bags separated at regular intervals in the longitudinal direction. Features.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A charcoal mattress of the present invention will be described with reference to the drawings. As shown in FIG. 4 which enlarges portion C in FIG. 3, the mattress containing charcoal of the present invention mainly includes an upper member A and a lower member B.

First, the structure of the upper member A will be described. As shown in FIG. 4, an upper fabric 1, a first nonwoven fabric 2, a cotton 3, a rigid polyurethane foam 4, and a second nonwoven fabric 5 are sequentially formed. As shown in FIG. 1, these are sewn in a stripe shape by quilting stitching, and at this time, a plurality of parallel stitches are formed on the upper member.
The parallel seam stitches the upper fabric 1, the first nonwoven fabric 2, the cotton (cotton) 3, and the rigid polyurethane foam 4, and defines a space between the upper fabric 1 and the first nonwoven fabric 2, thereby forming the upper fabric. A plurality of parallel bag-shaped spaces 6 are formed between the first nonwoven fabric 2 and the first nonwoven fabric 2. In each bag-shaped space 6, a strip-shaped wrapped carbon granule is inserted, whereby the upper member A is completed.

Next, the structure of the lower member B will be described. As shown in FIG. 4, the third nonwoven fabric 9, cotton (cotton) 10 and lower fabric 8 are sequentially superimposed, as shown in FIG. Then, the whole is sewn to an arbitrary pattern by quilting. The upper member A and the lower member B having the above-described configuration are superimposed on each other, and as shown in FIGS. And sewn together to form the shape shown in FIG.

In this embodiment, the upper fabric 1 and the lower fabric 8
Both sides of the rigid polyurethane foam 4 inserted between have a corrugated shape. The rigid polyurethane foam is made of rigid QD (TQ-1 standard), and is preferably formed to have a thickness of about 9 mm at a valley portion. By reducing the thickness of the rigid polyurethane foam 4,
Due to the rigidity, quilting stitching becomes very easy in the processing step, and the thickness of the entire futon becomes thin. In addition, the peaks of the rigid polyurethane foam 4 also provide a comfortable acupressure effect for the sleeping person. Cotton 3,1
Regarding 0, a blend of polyester cotton and cotton having a far-infrared effect is used, the amount of cotton to be inserted is less than half that of the conventional futon, and the weight of the entire futon is reduced.

The strip-shaped packaged carbon granules 7 are formed into a slender cylindrical shape using a flexible material, and a large number of bags are formed by thermal bonding, and each bag is uniformly filled with charcoal. This enhances the effect of charcoal. The charcoal contained in each bag of the wrapped charcoal granules 7 is made of high-temperature charcoal such as white charcoal and oak baked at a temperature of 900 degrees C. or high-capacity charcoal such as bamboo charcoal. Try to keep it down. As for the bag-like space into which the strip-shaped wrapping carbon granules 7 are inserted, relatively thin cloth such as plain weave or twill weave used for general mattress cloth is used to give room or play to the space. After the quilting process of A, the packaged carbon granules 7 are easily inserted. Cotton is also inserted on the side of the lower member B so that the sleeping person lying on the futon does not feel the floor feeling and enhances the antibacterial and insecticidal effects. In the quilting sewing of the lower member B, a seam is formed in a diamond type in FIG. 2, but other patterns may be used, and sewing can be performed with a freely arranged pattern. Therefore, the finish of the entire futon can be shown beautifully. The wrapping cloth 11 is made of an acrylic material, so that the futon finish is beautifully displayed, and the wrapping charcoal granules 7 are prevented from being scattered on the tatami mat or ondol even if the wrapping carbon granules 7 are torn.

[0017]

The charcoal mattress of the present invention has the rigid polyurethane foam 4 between the cottons 3 and 10, so that the fluffy feeling is suppressed as compared with the conventional cotton-only mattress.
The sleeping person feels the softness of the comfortable futon, and the acupressure effect of the rigid polyurethane foam 4 with upper and lower corrugations and the alkalinity of charcoal have a synergistic effect, improving the blood circulation of the sleeping person and adjusting the balance of body fluids. Therefore, it is also useful for preventing aging of sleeping people.

In this charcoal-coated mattress, the band-shaped bag-shaped space 6 is formed by a thin cloth, and the corrugated surface of the rigid polyurethane foam 4 gives room or play to the space. It is easy to do, and the charcoal is evenly stored in the package, so the charcoal has its own deodorant effect,
Moisture proof effect, negative ion effect, prevention of electromagnetic wave, purification,
Warming, aging effects and other effects can be further enhanced.

The far-infrared effect of the charcoal and the far-infrared effect of the cotton 310 overlap, and the thickness is smaller than that of the conventional futon, and the overall weight is lighter, so that it is convenient to carry. Hard polyurethane foam 4 which does not occupy too much storage space and has a thin finish, so it can be laid on a bed mat or laid on a conventional futon. As a result, flooring can be suppressed, so that even one sheet gives a comfortable sleep.

Furthermore, since the packed carbon granules 7 packed with charcoal having a dehumidifying effect are inserted between a large number of bag-shaped spaces, sweat and body fluids coming out of the body while the sleeping person goes to bed are eliminated. It eliminates the moisture of the futon, which makes the sleeper feel uncomfortable by infiltration, and the packed carbon granules directly hit the sleeper's body, so when the winter is cold, the warmth of the futon even without an electric blanket or red bean paste Because the cotton of the upper member and the cotton of the lower member are quilted, and the charcoal is packed in each of the plurality of bags of the package, both layers of cotton can be provided. Charcoal can be put evenly without collapsing.

In the charcoal-coated bedding of the present invention, packing charcoal packed with charcoal having an effect of preventing electromagnetic waves is inserted between a number of bag-shaped spaces. Prevents dust and dirt from sticking.
