Abstract

PURPOSE:To dehumidify a matters (in Japanese life, named SHIKIBUTON) by a method wherein the SHIKIBUTON contains, in a rolled cotton padding, plastic cores which have a large number of air vent holes penetrating the cores at right angles to the surface and arranged in both the longitudinal and the transverse directions of the cores. CONSTITUTION:A rolled cotton padding 1 comprises a surface layer 2 and a rear surface layer 3 and has three cores 4 therebetween, and the surface layer 2 and the rear surface layer 3 are sewn together around the periphery of the padding 1 and in each mid-position between the cores 4. The cores 4 are made of plastics (foamed polypropylene or foamed polyethylene) and have a large number of air vent holes 5. Each air vent hole 5 is round-shaped, penetrates the core 4 at right angles to the surface, and is arranged in both the longitudinal and the transverse directions of the core 4. Consequently, a high air permeability is obtained by the air vent holes 5 and the SHIKIBUTON does not significantly get damp, even when a great amount of perspiration evaporates.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress.

[0002]

2. Description of the Related Art Up to now, there has been used a cotton cloth containing a urethane core as a cover. Instead of the urethane core, another plastic core may be accommodated. Compared with cotton and feather-containing bedding, the plastic bedding-containing bedding is simpler and more economical, and it may be popular in the future, but the problem is ventilation. There is no nature. While sleeping, the user sweats a lot, and the amount is said to reach 1.8 liters. For this reason, when a person sleeps on a bed with a plastic core housed therein, there is a problem in that the bed is not breathable, so that the bed is extremely damp and hygienic.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention has been made for the purpose of removing the moisture in a mattress containing a plastic core inside a cotton swab.

[0004]

According to the present invention, a large number of vent holes extend in the thickness direction of the core and penetrate the core, and the vent holes are arranged in the length direction and the width direction of the core.

The core is preferably made of expanded polypropylene or expanded polyethylene. Further, it is preferable that a large number of protrusions are formed on the upper surface of the core between the ventilation holes.

[0006]

Description of Embodiments Embodiments of the present invention will be described below.

In FIG. 1, this bed has a quilted cotton 1 and its length L1 is 2000 mm.
And the width W1 is 1000 mm. As shown in FIG. 3, the cotton swab 1 comprises a front material 2 and a lining material 3. Further, as shown in FIG. 2, three cores 4 are accommodated in the cotton swab 1, and the outer material 2 and the lining 3 are sewn to each other around the cotton swab 1 and between the respective cores 4. In this embodiment, as the outer material 2 and the inner material 3, the natural material wool cotton covered with a non-woven fabric is used. The core 4 is made of plastic, is made of expanded polypropylene or expanded polyethylene, and has a length L2 of 600 to 615 mm,
The width W2 is 860 to 900 mm, and the thickness T is 20 mm.
Is.

The core 4 has a large number of ventilation holes 5. The vent hole 5 is a round hole, extends in the thickness direction of the core 4, and penetrates the core 4. Its diameter D1 is 20 mm. The vent holes 5 are arranged in the length direction and the width direction of the core 4, and the interval C is 60 mm.

[0009] Therefore, when sleeping with this bed,
The ventilation holes 5 of the core 4 provide air permeability and remove moisture. Therefore, even if the user sweats a lot during bedtime, the bed does not have a noticeable humidity, which is preferable in terms of hygiene. Even a sick person such as a so-called bedridden elderly person who sleeps for a long time can remove moisture by the air permeability and thereby prevent bed sores.

Further, the core 4 is made of expanded polypropylene or expanded polyethylene, which has appropriate strength and elasticity, and expanded polyethylene is also the same. Therefore, sleeping comfort can be improved by strength and elasticity. The bulkiness of the core 4 is not impaired. It is also possible to reduce the weight of the bedding by using expanded polypropylene or expanded polyethylene. It is also possible to fold three sheets of mat between each of the cores 4, and it is easy to carry and store.

FIG. 4 shows another embodiment. The mattress 4 is composed of a cotton roll 1 and a core 4, and the core 4 has a large number of ventilation holes 5. Further, a large number of protrusions 6 are formed on the upper surface of the core 4 between the ventilation holes 5. As shown in FIG. 5, the protrusion 6 has a round shape and is integrally formed with the core 4, and the height H thereof is 20 mm and the diameter D2 thereof is 40 mm. Except for the protrusion 6, the other configurations are the same as those of the mattress of FIG.

Therefore, when the person lays down on the bed in FIG. 4, not only the ventilation hole 5 of the core 4 provides the air permeability, but also the projections 6 provide the acupressure and the massage effect, so that the whole body is loosened and the blood circulation is improved. Is improved. This can relieve and treat stiff shoulders and low back pain. The core is made of expanded polypropylene or expanded polyethylene. Therefore, the protrusion 6 can be provided with appropriate strength and elasticity, and its acupressure and massage effects can be enhanced. Furthermore, when sleeping on the bed, a space is formed between the protrusions 6, which improves the air permeability, which is preferable.

[0013]

As described above, according to the present invention, air permeability is obtained by the air holes 5 of the core 4, and moisture is removed. Therefore, even if the user sweats a lot during bedtime, the bed does not have a noticeable humidity, which is preferable in terms of hygiene. Even a sick person, such as a so-called bedridden elderly person, who sleeps for a long time can remove moisture due to breathability, thereby preventing bed sores and achieving the intended purpose.
