The problem that the invention is trying to solve

As a result, there were the following problems.
It has been practiced so far to provide an aluminum vapor deposition layer between the fabrics of the futon to increase heat retention. However, it is important that the reflective material such as the aluminum deposition layer has high reflective performance and radiation performance, and in order to utilize these performances, at least one side of the reflective material needs space for reflection and radiation.
If the reflector and other materials are used in contact, it will lead to conductive heat transfer. The reflective material has a high thermal conductivity, and if it is used in such a manner, the heat is rather easily transmitted, and the heat insulation performance is greatly reduced.
The present invention has been made to solve these problems.

BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described below.
In winter, when you enter the futon 1, you feel cold, but eventually the futon 1 is warmed by your body temperature, and the heat is kept by the filling 3 or the like, and you feel the warmth little by little.
It would be nice if I could sleep until morning while maintaining that state, but sometimes I wake up feeling cold and often go to the bathroom. This tendency increases with age.
It seems that there are various causes of waking up at night, but the sleeping environment also greatly affects it. For example, there is a report that the temperature inside the futon 1 is 32 to 34° C. and the humidity is around 50%, which is a good environment.
Even if you go to bed in this state, the room temperature will be at most around 23°C, and the temperature difference with the futon 1 will be 10°C or more. That is, heat is constantly transferred from the futon 1 toward the room. Radiant heat is the greatest of these heats, and the emissivity of the futon 1 and the like is as high as 95%. If you try to maintain the temperature of the futon 1, the futon 1 will take heat from your body to that extent, and your body temperature will drop.

Electric blankets and the like are often used as countermeasures against the cold in winter.
If you turn on the electric blanket in advance, the warmth will be transferred to your cold skin from the moment you sleep and you will feel comfortable. While awake, the comfort can be maintained continuously by adjusting the temperature.
However, the body temperature decreases with time. Then, a temperature difference with the body temperature is generated, it is hot and the futon 1 is slipped on, and the comfort is lost all too soon.
That is, even if a heat source higher than the body temperature is supplied from the outside of the body, the heat balance may be disturbed and a comfortable sleep may not be possible.

The present invention is a low-radiation bedding structure constructed in bedding, wherein at least one side of a futon 1, a blanket, or a low-density resin sheet or fiber layer 6 is provided with an aluminum deposition layer 4, and the aluminum This low radiation bedding structure is characterized in that the deposition layer 4 is formed closer to the skin than the futon 1, blanket, low-density resin sheet or fiber layer 6. - 特許庁

While mattresses provided with an aluminum vapor deposition layer 4 inside the mattress 1 are on the market, the present invention is completely opposite to this and the aluminum vapor deposition layer 4 is formed on the outer skin side of the mattress 1 .
In the case of a blanket, a low-density resin sheet, or a fiber layer 6, an aluminum vapor deposition layer 4 is formed on one side.

In general, it is said that the thicker the futon 1 or the blanket, the more air can be contained, and the higher the heat insulation. However, in the present invention, it is important that the aluminum deposition layer 4 is applied to the surface of the futon 1 or blanket on the outdoor side, and the thickness or material of the futon 1 or blanket does not matter at all.

The aluminum vapor deposition layer 4 is constructed by general vacuum vapor deposition or the like, but the construction method or the like is not particularly limited. The high-purity aluminum vapor deposition layer 4 is a material with high reflectance to radiant heat, and is used in many places.
However, in order to fully exhibit its performance, it is efficient to utilize the low radiation performance of the aluminum vapor deposition layer 4, and it is most preferable that there is no contact with anything and that the layer is in contact with the atmosphere. In general, the reflectance of the aluminum deposition layer 4 alone has a high value of 95% to 98%.
Further, the vapor-deposited aluminum layer 4 has a high moisture permeability and can discharge the water vapor emitted from the human body to the outside, so that the futon 1 does not easily accumulate moisture.

In the present invention, an aluminum vapor deposition layer 4 is provided on one side of the futon 1, blanket, low-density resin sheet or fiber layer 6, and the aluminum vapor deposition layer 4 is the futon 1, blanket, or low-density resin sheet or fiber. The low radiation bedding structure is characterized in that it is formed closer to the skin than the layer 6, and the colored layer 9 is formed further outside.

The futon 1, blanket, or low-emissivity mat is mostly used indoors, but the aluminum vapor deposition layer 4 has a high reflectance of 95 to 98%, and if it hits the proof, it will be shiny and uncomfortable. Therefore, a coloring layer 9 is provided on the outdoor side of the aluminum deposition layer 4, or the material is colored.
As a result, when the colored layer 9 is formed on the outer side of the vapor-deposited aluminum layer 4, the emissivity is lowered to 5 to 75%, but compared with the bedding 1 of 95%, the performance is high, so there is no problem.

The mechanism of the futon 1 in which the aluminum deposition layer 4 is formed on the surface of the cloth 2 will be explained.
In this case, completely opposite performances are used when applied to the quilt 1 and when applied to the quilt 1, so they will be described separately. First, the case of using the quilt 1 will be described.
In this case, since heat moves from the body toward the outdoor side, the aluminum deposition layer 4 is provided on the outdoor side to utilize the low radiation performance.
The heat transferred from the body to the futon 1 is transferred in three forms: conductive heat, convection heat, and radiant heat. The futon 1 is characterized in that it is made thick by using cotton, feathers, etc., and uses air, which is difficult to transmit heat, as a heat insulating medium. Using air for heat insulation means that there is a lot of space, and it is thought that the influence of radiant heat is also great.
The heat transfer from the body to the futon 1 takes the form of conductive heat through contact, is transmitted to the fiber layer 6 of the batting 3 and the air layer 7, and eventually heats to the fabric 2 on the outside of the futon 1. On the other hand, since the fabric 2 has a low density, the radiant heat radiated from the body passes through the fabric 2 on the side of the body, and the heat is transferred directly to the outer fabric 2, which may generate heat.
The heat transferred to the outer fabric 2 in this manner is transferred to the low-temperature indoor air, and the greatest heat transfer at this time is radiation of radiant heat. The emissivity of the fabric 2 is as high as 95%, and a large amount of heat is taken away from the surface of the fabric 2 immediately.
In the present invention, the surface of the fabric 2 is provided with an aluminum deposition layer 4 on the outdoor side.
The aluminum deposition layer 4 has an emissivity of radiant heat of about 5 to 10%, and it is possible to create a situation in which the radiant heat is hardly radiated from the surface of this layer.
On the other hand, inside the blanket 1, most of the radiant heat transmitted through the padding 3 is reflected by the aluminum vapor deposition layer 4 and returned to the padding 3 side to become heat for keeping the blanket 1 warm. Furthermore, the conductive heat that tends to move from the batting 3 to the outside is blocked by the aluminum deposition layer 4 and stays in the batting 3 . In this way, very little heat is transferred from the vapor-deposited aluminum layer 4 to the outside, and the futon 1 is reliably kept warm.
Also, the heat transferred from the body temperature does not exceed the body temperature, and a comfortable temperature environment can be obtained.
There is another big difference between using only the blanket 1 and using the aluminum deposition layer 4 . In the futon 1, the temperature of the air inside the batting 3 gradually decreases toward the outside. The temperature of the space between them is almost the same. In other words, in this space, heat of almost the same temperature as the body stays, and heat transfer is small, so that a very comfortable environment can be created.
Next, the case of using the mattress 1 will be described.
In this case, since heat is transferred from the body temperature toward the floor, the aluminum deposition layer 4 is used on the human body side. That is, in this case, the reflection performance of radiant heat is utilized.
However, when the aluminum vapor deposition layer 4 and the body come into contact with each other, a large amount of conductive heat is transferred from the aluminum vapor deposition layer 4 having a high thermal conductivity to the human body, resulting in an adverse effect. Therefore, it is preferable to use a blanket with low density between both sides to create a space where radiant heat can be generated.
In this case, the radiant heat radiated from the body is transmitted through the blanket, reflected on the surface of the aluminum deposition layer 4, and returned to the body. Since your own heat is returned, it can be said that it is a very comfortable temperature.
Of course, heat is also transferred from the body, but the low-density blanket placed between the body and the aluminum deposition layer 4 prevents this, so a warm environment can be created.

In the present invention, an aluminum vapor deposition layer 4 is provided on one side of the futon 1, blanket, low-density resin sheet or fiber layer 6, and the aluminum vapor deposition layer 4 is the futon 1, blanket, or low-density resin sheet or fiber. A low-emissivity bedding and a low-emissivity mat 8 formed on the skin side of the layer 6 and further formed with a colored layer 9 on the outer side thereof, and are rounded or U-shaped so that the head is placed on one side of the plane in the longitudinal direction. We also propose a low-emissivity bedding and a low-emissivity mat with notches in the .

In this proposal, the blanket 1 on both sides of the head is hung up to the shoulders, and the head is hung up to the neck on either the flat part of the blanket 1 or the blanket provided with the aluminum vapor deposition layer 4 on the surface. The bedding has U-shaped cutouts.
It is common to sleep with a futon 1 or a blanket over your neck, but everyone has experienced cold shoulders. Therefore, in this proposal, a part of the futon 1 or the blanket is extended to the shoulders. Of course, since the aluminum vapor deposition layer 4 is provided on the outdoor side of the futon 1 and the blanket, it goes without saying that the projecting portion is also warm.

[Heat shield test 1]
A commercially available blanket with a thickness of 3 mm was placed on the subject's body, and a thermal insulation material with a thickness of 3 mm called THB-JP3 (manufactured by Nippon Thermal Shaft Co., Ltd.) having an aluminum deposition layer was placed thereon. THB-JP3 is composed of a colored layer, an aluminum deposition layer, and polyester cotton. The weight is 80 g/m ² and the reflectance is 73-79%.
Room temperature was 21°C.
After 10 minutes, the surface of the blanket and the surface of JP3 were thermographically measured.

[Result 1]
Both temperatures are below.
The surface temperature of the colored layer was as low as 3.2°C.
(1) Colored layer surface temperature: 21.7°C
(2) Blanket surface temperature: 24.9°C

[Discussion 1]
b) The lower the temperature radiated from the inside to the outside, the higher the heat retention performance. In this test, the colored layer is as low as 3 or 2°C, indicating good heat retention performance.

Effect of the invention

It is often said that the use of the futon for bedding or the mat of the present invention warms the body to the core. In addition, many elderly people say that the number of times they use the toilet at night has been halved.

The low radiation mat for bedding has a very low density, so it can be shrunk and stored, and can also be used as a heat insulating mat for emergency evacuation.
