Description

[Detailed description of the device]

[0001]

[Field of use of the device]

 The present invention relates to a bed mat containing activated carbon used as a bed pad or a bedding.

[0002]

[Prior art]

 Most conventional bed pads and beddings containing activated carbon simply have activated carbon packed inside. In consideration of hygiene, these are wrapped with activated carbon in cloth with good air permeability. It is essential for the comforter to have good breathability and moisture absorption for comfortable sleep and health, and the bedding material must take these conditions into consideration.

However, in the case of the activated carbon mat, if the activated carbon is enclosed by using a cloth or the like having good air permeability, it is inevitable that the activated carbon spills out of the futon or the like with use. On the other hand, if a dense material that does not easily spill activated carbon is used, not only is it not suitable as a bedding material because of its poor breathability, it also has the effect of activated carbon such as hygroscopicity, deodorization, and heat (far infrared effect). There is no meaning to enclose activated carbon.

[0004]

[Challenges of device]

 The subject of this invention is 1) to provide a mat with high air permeability and to which activated carbon does not spill (claims 1 to 5), 2) enclose activated carbon tightly to prevent generation of fine powder, and enclose activated carbon. To prevent the sheet from losing its shape (Claims 1 to 5), 3) In combination with antibacterial, tick-proof, and deodorizing batting, the hygroscopicity, deodorizing property, and heat resistance (far infrared effect) of activated carbon, etc. In addition to the effect of (1), a synergistic effect is obtained (Claim 5).

[0005]

[Constitution of device]

 This invention has two fine mesh fabrics for enclosing activated carbon, and this fabric is provided with a large number of corrugations, and the two corrugations of the two fabrics are provided at the valleys of the corrugations. A large number of corrugated bags are bonded to each other to form a sheet member, and the corrugated bags of the sheet member are each filled with activated carbon (claim 1). Here, preferably, a non-woven fabric having a finer mesh than 20 mesh is used for the fine mesh fabric (claim 2).

In addition, this invention has two non-woven fabrics having a mesh finer than 20 mesh for enclosing activated carbon, and at least one non-woven fabric is provided with a large number of corrugated parts, and the non-woven fabric having the corrugated parts is provided. The other non-woven fabric is bonded at the valley of this corrugated part to form a number of corrugated bags, and each corrugated bag is filled with activated carbon to form a sheet member. The sheet member is housed with the non-woven fabric provided with the corrugated portion as the upper surface, and the cloth is arranged on the upper surface and the lower surface of the batting (claim 3). Here, it is preferable that a plurality of the sheet members enclosing the activated carbon are connected to each other to form a flat surface and housed in a mat (claim 4). More preferably, this batting is subjected to antibacterial, anti-mite and deodorizing treatment (claim 5).

[0007]

[Function of the invention]

 In this device, a fine mesh cloth is used to enclose the activated carbon. Activated carbon is enclosed with a non-woven fabric having a finer mesh than 20 mesh (Claim 1). Most non-woven fabrics with a mesh finer than 20 mesh will not spill most activated carbon particles. Moreover, if a non-woven fabric is used, its breathability is not inferior to that of a fabric.

Here, the encapsulation of the activated carbon in the non-woven fabric is performed by forming a number of corrugated parts on the non-woven fabric and bonding the non-woven fabric to another non-woven fabric to form a corrugated bag, and filling the activated carbon so that the activated carbon is tightly enclosed. That is, two non-woven fabrics provided with a large number of corrugated parts are used and bonded to each other at the troughs of each corrugated part (claims 1 and 2), or a non-woven fabric provided with corrugated parts is formed in the troughs of the corrugated part. In this section, a non-woven fabric having no other corrugated portion is attached (claim 3), and the inside of each of these corrugated bags is tightly filled with activated carbon to form one sheet member. Here, “hardly filling” means filling activated carbon with no gaps.

This sheet member has a band shape with an arbitrary width and length, and the number and size of corrugated bags and the amount of activated carbon to be filled are also arbitrary. In addition, it is preferable that a plurality of sheet members are connected laterally to have a planar shape in accordance with the size of the mat and used as one sheet (claim 4). Since the activated carbon is divided into a number of corrugated bags and is packed tightly, this is equivalent to providing a number of hard protrusions on the sheet material. If the activated carbon is divided and filled tightly in this way, the activated carbon is held in a fixed state, and fine powder is unlikely to be produced. When this sheet is used in combination with batting having antibacterial, anti-mite, and deodorizing effects, a synergistic effect is obtained in addition to the hygroscopicity, deodorizing property, and heat resistance of activated carbon (claim 5).

【Example】

 FIG. 1 shows the activated carbon mat of the example. 2 is an activated carbon mat, and 4 is an activated carbon sheet. 6 is a strip-shaped sheet piece provided with a large number of corrugated bags (shown in FIG. 2) for filling the inside with activated carbon, and the sheet pieces 6 are laterally connected to each other to correspond to the size of the mat 2. One sheet 4. 8 is a batting provided so as to sandwich the sheet 4, 10 is a batting placed on the upper surface of the batting 8, and 12 is a dress material on the upper surface of the mat 2.

FIG. 2 shows a sheet piece 6 of the embodiment, and FIG. 3 shows a cross-sectional view of the sheet piece 6 of FIG. 2 in the YY direction. 14 is a corrugated nonwoven fabric, 16 is a back nonwoven fabric, and a large number of corrugations are formed on the corrugated nonwoven fabric 14. The inside of each of these corrugations is filled with activated carbon 18 (shown in FIG. 3), and the corrugated non-woven fabric 14 and the back non-woven fabric 16 are bonded by thermocompression bonding, adhesive, sewing machine stitch, etc. at the corrugated troughs 20. Are bonded together to form a corrugated bag 15 to form a sheet piece 6. Nonwoven fabrics 14 and 16 that do not pass 20-mesh activated carbon are used. Nonwoven fabrics with a finer mesh than 20 mesh, for example, a fiber diameter of 0.5 to 5 microns and a ventilation of 25 cm ³ / cm ² / sec (air permeability Is based on JIS L-1096 Frazier method). The length and width of the sheet piece 6 and the size of the corrugated bag 15 are arbitrary, but the amount of activated carbon to be filled inside should be such that the corrugated bag 15 can be formed firmly, and the bag 15 can be packed in large quantities. Prevents the shape of the

In the examples, the non-woven fabrics 14 and 16 made of 100% polyethylene were used, but the present invention is not limited to this. Fine mesh other than non-woven fabric may be used, but the non-woven fabric used in the examples is that the non-woven fabric is even finer than the fine mesh fabric and is a filter for preventing fine powder from spilling out. This is because it is highly effective, does not easily lose its shape, and is easy to work such as press-fitting and easy to handle. The corrugated bag 15 is filled only with the activated carbon 18, but if the activated carbon 18 is not 100%, for example, a chip of cypress or cedar may be mixed to obtain a comfortable sleep due to the antibacterial effect and aroma.

FIG. 4 shows a cross section of a main part of the mat 2 of FIG. 1 in the XX direction. Reference numeral 22 denotes a lining of the mat 2, which includes the inside 10 and the outside 12 and encloses the batting 8 and the activated carbon sheet 4 provided therein. The sheet 4 is formed by connecting a plurality of sheet pieces 6 by sewing machine stitching or thermocompression bonding, and the batting 8 and the inside 10, the outer material 12 and the lining 22 arranged outside the sheet 4 are quilted with the sewing machine stitch 24. Then, the sheet 4 or the batting 8 and the cloth such as the cloth 10 are fixed. Here, the batting 8 is made by knee bread processing, etc., and the fibers are piled up and hardened. Even if the fine powder of the activated carbon 18 spills from the nonwoven fabrics 14 and 16, it is further spilled outside the batting 8. To prevent. If fine cloth is also used for the inner layer 10, the outer layer 12, and the lining 22, fine powder of the activated carbon 18 will not spill out of the mat 2. In addition, the batting 8 should have anti-tick, antibacterial and deodorizing effects. Further, the same effect may be imparted to the outer material 12, the lining 22, and the inner material 10.

FIG. 5 shows a modified sheet piece 60. In the sheet piece 6, the corrugated non-woven fabric 14 and the back surface non-woven fabric 16 are pressure-bonded, but two corrugated non-woven fabrics 140, 140 may be used and the corrugated troughs 200, 200 may be similarly pressure-bonded.

As described above, in the embodiment, the nonwoven fabrics 14 and 16 are used and the activated carbon 18 is filled therein. Nonwoven fabrics 14 and 16 were used because ordinary fabrics have good breathability, but they cannot completely prevent the activated carbon fine particles from spilling out. Bedding is used every night, and it is unavoidable that the activated carbon inside gradually spills outside due to friction and pressure applied to the mat during movement during sleep, sun drying, storage, etc. In the case of mats, the deterioration is even faster, and when used for a long period of time, the particles of activated carbon become finer, making them more likely to spill out, making the feeling of use worse and making maintenance difficult. Especially for sick people, bedding is used almost all day, so the deterioration is remarkable. However, as long as it is bedding, it is indispensable to be hygienic, and it is not possible to use non-breathable materials such as vinyl sheets. In the embodiment, the non-woven fabrics 14 and 16 in which the activated carbon 18 of 20 mesh is trapped and does not spill out are used. The non-woven fabric has a thickness and has a structure similar to that of a plurality of finely woven fabrics stacked together. In other words, even if a single piece of cloth passes through fine powder, it hardly passes through multiple pieces, and the activated carbon is wrapped in multiple layers of filters. Furthermore, since it is a non-woven fabric, it has better breathability than when multiple fabrics are stacked. In the embodiment, since the non-woven fabrics 14 and 16 which do not pass the activated carbon 18 having a fineness of 20 mesh are used, it is possible to use fine particles of activated carbon such as regenerated activated carbon.

The inventors tried to use a mat in which the non-woven fabric was made into a bag shape and simply packed the activated carbon inside, but completely shut out the spillage of the activated carbon fine powder even though the non-woven fabric encloses the activated carbon. I couldn't do that, and fine powder spilled out of the mat little by little as I used it. By simply enclosing activated carbon in the bag-shaped non-woven fabric as described above, the activated carbon can freely move within the non-woven fabric bag. If the activated carbon moves freely due to pressure, twist, friction, etc. on the mat during use, friction will be generated between the activated carbon and the non-woven fabric, or between the activated carbon, and the activated carbon will be pulverized to the outside of the non-woven fabric. In the embodiment, a large number of corrugated bags 15 are provided by the non-woven fabrics 14 and 16 to form the sheet piece 6, and the corrugated bag 15 portion of the sheet piece 6 is tightly filled with activated carbon 18. Therefore, the activated carbon 18 is divided into small blocks and is confined without any gap, and the activated carbon 18 moves with almost no deformation of the corrugated bag 15 even when the mat 2 is pressed, twisted, or rubbed due to use. do not do. As a result, there is no friction between the activated carbons 18 and there is almost no pulverization. Further, since the activated carbon 18 has a corrugated shape and hardly moves, it becomes more difficult to spill out of the nonwoven fabrics 14, 16. Since the activated carbon 18 is tightly filled in the corrugated bag 15 as described above, the bag 15 is not easily deformed even when weight is added, and the acupressure effect on the human body is produced. Furthermore, since there are many valleys 20, a gap is created between the activated carbon sheet 4 and the battings 8 and 8, and the air permeability is further improved.

Far-infrared ray effect, moisture absorption effect, deodorizing effect and the like are known as effects of activated carbon. Therefore, it is possible to use activated carbon in bedding to warm the body and absorb moisture and odor generated from the body to obtain comfortable sleep. Since the non-woven fabrics 14 and 16 having high air permeability are used in the examples, the above-mentioned effects of activated carbon can be efficiently exhibited. Since a large number of corrugated bags 15 are provided, the area of the sheet 4 on the body is increased, and a more remarkable effect can be obtained.

In addition to this, in the embodiment, the batting 8 which has been hardened by knee pan processing or the like is provided with antibacterial, anti-mite and deodorizing effects and is used together with the activated carbon sheet 4. It is also possible to use only the activated carbon sheet 4 to form a bed pad. However, by using a combination of the batting 8 having the antibacterial, tick-proof and deodorizing effects and the activated carbon sheet 4, a more suitable bedding can be obtained. For example, the activated carbon 18 absorbs dust and mites, and if the surrounding area is wrapped with batting 8 having an antibacterial and tick-proof effect, the mites cannot survive in the mat 2.

Next, the result of a clinical test using the activated carbon mat 2 of the example is shown. Table 1 shows the results of the clinical trial, which was performed on 20 long-term bed rest patients who were hospitalized. Table 2 shows the results of a test in a general household, which targeted 40 people. In each case, the monitoring period was 30 days, and the activated carbon mat 2 was used by placing the mat 2 of the embodiment on a bed mat (spring type urethane mat) placed on a bed apparatus and using cotton Wrapped in 100% sheets.

According to this clinical test, the effect of the test for long-term bed rest patients in Table 1 is remarkable. As described above, according to the activated carbon mat 2 of the embodiment, the sleeping comfort is improved, and in particular, various unpleasant symptoms of a sick person are alleviated. Reducing patient discomfort and symptom in this way provides a comfortable nursing environment for the nurse.

The mat 2 of the embodiment may be used as a bed pad or a futon alone, may be used in combination with a futon, or may be integrally incorporated in the mattress. Furthermore, the activated carbon sheet 4 of the embodiment is thin and easy to handle, and can be easily attached to the mat 2. Furthermore, since the sheet 4 can be easily taken out from the mat 2, it can be reused after being subjected to a regeneration treatment such as heating.

[0024]

[Effect of device]

 This device has the following effects. 1) Prevents activated carbon particles from spilling from the non-woven fabric, making it possible to use activated carbon with fine particles such as recycled activated carbon. Moreover, since it is a non-woven fabric, its breathability is not inferior to that of cloth. 2) Since the activated carbon is divided into a number of corrugated bags and is filled tightly, it is equivalent to providing a number of hard protrusions on the sheet material, and it is difficult to lose its shape, and as a result fine powder of activated carbon is not generated. 3) The corrugated protrusions increase the air permeability, and the area of the sheet increases, and the effects of activated carbon such as hygroscopicity, deodorizing property, and thermal property (far infrared effect) can be effectively used. 4) The corrugated protrusions create an acupressure effect, further enhancing the usability. 5) When activated carbon sheet is used in combination with antibacterial, tick-proof and deodorizing batting, synergistic effect is obtained in addition to hygroscopicity, deodorization and heat resistance of activated carbon. 6) By the above 3) to 5), comfortable sleep can be obtained, especially the sick person's unpleasant symptoms are alleviated and the psychological burden is reduced, and a comfortable nursing environment can be provided to the nurse. 7) The activated carbon sheet is thin and easy to handle, can be easily put on and taken out from the mat, and can be reused after being subjected to a recycling treatment such as heating.
