Abstract

PROBLEM TO BE SOLVED: To reduce touching areas of a cushion to a human body to make a cushion excellent in heat insulation and dehumidification and be suitable for using as bedding for a patient, by wrapping a core material formed of a plate honeycomb structure with a number of through holes passing through from surface to back side by a cloth of mesh fabric cover. SOLUTION: When this cushion 1 is used as, for instance, a bedding mat, the cushion 1 is placed between a bed mat or futon and a sheet and suitably placed on a part around from the back to the waist for use. Because a core material 2 wrapped in a cloth cover 3 of the cushion 1 has a plate honeycomb structure, the area touching on skin is small to demonstrate an excellent position distributing function. And, because the core material 2 has a number of through holes vertically passing through, air permeability is excellent and has heat retaining effect since heat energy discharged from a human body is accumulated in spaces of the through holes. Moisture on the skin surface is easily evaporated to prevent wet feeling since those through hole parts are spaces. Consequently the cushion can be used regardless of season all the year round.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rug excellent in breathability and dehumidification and suitable for use as bedding, cushions and the like.

[0002]

2. Description of the Related Art Futons, blankets,
Mats are flexible, have high adhesion to the body, and have heat retention.However, they generally have low air permeability and are difficult to release moisture. was there. For this reason, in the case of a bedridden sick person or the like for a long period of time, there has been a problem that pressure ulcer easily occurs due to bedding.

[0003] On the other hand, electric blankets are used for heating in winter, but when this kind of electric blanket is used as bedding, there is also a problem that the user often feels lazy or tired after use, and sleep is impaired. .

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in conventional bedding and the like, and has a small contact area with the body, has excellent heat retention and dehumidifying properties, and is suitable for use as a patient's bedding. The task is to provide suitable rugs.

[0005]

In order to solve the above problems, the present invention employs the following configuration. That is, the rug according to the present invention is characterized in that a core material composed of a plate-shaped honeycomb structure having a large number of through holes communicating with the front and back is wrapped with a cloth or mesh cover. As the honeycomb structure, a paper structure having appropriate strength can be used. Further, it is preferable that the cover is subjected to far-infrared radiation treatment and / or antibacterial treatment.

In this rug, the core is a plate-shaped honeycomb structure having a large number of through-holes communicating with each other on the front and back sides. Therefore, the body is supported only by the peripheral portion of the through-hole in plan view. It is a net-like part. Therefore, there is little adhesion to the body, excellent moisture release, and less sticky feeling. Since the core is covered with a cloth or mesh cover, the body is slightly supported by the cover not only in the mesh portion but also in the through hole. For this reason, a load is not applied only to the net portion of the core material, and the skin does not have excessive unevenness or local pain.

[0007] Further, the rug has excellent heat insulating properties and heat insulating properties because the large number of through-holes are spaces insulated from the outside air. Further, even if a large number of through holes are provided in the core material for supporting the body, since the whole has a honeycomb structure, it can sufficiently withstand a load in terms of strength.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below. FIG. 1 illustrates an embodiment of the present invention. The rug 1 includes a core material 2 wrapped in a bag-shaped cover 3. The core material 2 is a honeycomb structure made of an elongated plate material 4 having appropriate strength, such as cardboard, plastics, etc., and has a parallel frame portion 2a, arranged in a substantially straight line.
A corrugated frame portion 2b arranged at an interval between the parallel frame portions 2a,..., And a section surrounded by the frame portions 2a, 2a, 2b communicates with both front and back (upper and lower) surfaces of the core material 2. The triangular through holes 5 are formed.

The through-hole 5 in this embodiment has a substantially triangular cross section as shown in FIG. 2, for example, a hexagon or other polygon as shown in FIG. 3, a circle as shown in FIG. Other shapes are possible. If the thickness of the frame portions 2a and 2b constituting the peripheral portion of the through-hole portion 5, that is, the plate material 4 constituting the core material is too thin, the strength may be insufficient, and moreover, local pressure is excessively applied to the skin. Not preferred.
On the other hand, if the thickness is too large, the cross-sectional area of the through-hole portion 5 becomes too small, and there is a possibility that the air permeability, the heat retaining property and the like may be reduced, and the rigidity and the weight are undesirably increased. Therefore, it is preferable that the thickness of the plate member 4 constituting the core member 2 be about 1 to 3 mm. The cross-sectional area of the through hole 5 is
It is preferable to set it to about 0.5 to ³ cm ² . Further, the preferable vertical width of the core material 2, that is, the thickness T of the rug 1 varies depending on the application, but is usually several mm to several tens mm. However, the thickness of the plate 4, the shape, the cross-sectional area of the through hole 5, the vertical width of the core, and the like are not limited to these ranges.

The cover 3 surrounding the core 2 is made of a cloth woven from natural fibers or chemical fibers. This cover 3
For example, it is convenient to form a bag having one end opened like a cover of a mattress, and to insert the core material 2 therefrom. The cover 3 is preferably subjected to a well-known far-infrared radiation treatment, deodorization and antibacterial treatment. It is said that applying infrared radiation treatment to wearables and bedding will improve the blood circulation of the user and can be expected to warm from the core of the body. It can be expected to have an excellent effect that you can sleep comfortably without feeling lazy. In addition, when deodorant and antibacterial treatments are given, it is hygienic,
The usability is also improved.

As a cover for directly wrapping the core material 2, a mesh-shaped cover 3A as shown in FIG.
May be used. If the core material 2 having a honeycomb structure is wrapped with a mesh cover 3A made of chemical fiber such as nylon having relatively high strength, the air permeability is not impaired, and the unevenness of the surface of the core material 2 can be reduced. it can. It is preferable that the mesh roughness of the cover 3A of the mesh is smaller than the cross-sectional area of the through hole of the honeycomb structure of the core material 2.
When the mesh cover 3A is used, it is preferable that a normal cloth cover or cloth sheet is further put on the cover.

The rug 1 can be used as bedding, floor mats, cushions and the like. When the rug is used, for example, as a bedding mat, the rug is laid between a bed mat or a mattress and a sheet, and is appropriately arranged from the back to the waist. In this rug, since the core material wrapped by the cloth cover has a honeycomb structure, the rug has a small adhesion area to the skin and exhibits an excellent posture dispersing function. Also, since a large number of through-holes 5,... Communicating vertically with the core material are provided, the ventilation is excellent and heat energy released from the body is accumulated in the space of the through-hole 5. Therefore, there is a warming effect. Since these through-holes are spaces, the moisture on the surface of the skin is easily evaporated, and the feeling of stickiness is less likely to occur. Therefore, it can be used all year round regardless of the season.

Although the core 2 has a moderate strength, it is somewhat flexible as a whole and can have an appropriate hardness, so that, for example, a spine correction effect can be expected. In addition, as a plate material constituting the core material 2,
If you use thick paper etc. that reused waste paper, the feeling of use is good,
It is also excellent in resource recycling.

As described above, this rug is used, for example, as a bedding for patients to help prevent pressure ulcers, and is further used as a cushion, a backrest of a driver's seat of a car, a pillow and the like. You can also. Further, it is suitable for use as a substitute for a heating product such as an electric blanket in winter. For example, it is suitable as bedding for people with low back pain and coldness. Furthermore, the effect of correcting the spine can also be expected.

[0015]

As described above, since the rug according to the present invention is obtained by wrapping a core material having a honeycomb structure with a cloth or mesh cover, the rug has excellent air permeability, dehumidifying property, heat insulating property and the like. It became suitable for use as patient bedding, cushions, driver's seat backrests, pillows and the like.
