Description

[Detailed description of the invention] 3. Detailed description of the invention (1) Purpose of the invention (a) Conventional technology As thermal clothing, there are bedding that uses cotton or feathers as a thermal insulation material, and even clothing that uses the fabric itself. There are many types of clothing such as fur coats and overcoats that have the purpose and effect of keeping you warm, and cold weather clothing that uses cotton, wool, feathers, etc. as a heat insulator between the fabrics. All use cotton (natural cotton, chemical fiber cotton, etc.) or feathers as a heat insulating material, and either they are covered with cloth fabric in the required form, or they are made of fabric itself that has a heat insulating effect, such as fur. The conventional technique was to manufacture winter clothing and the like having a desired shape.

(b) Problems with the conventional technology When trying to increase the effect of heat retention or cold protection using the above conventional technology, no matter what kind of insulation material is used, it is necessary to use a larger amount of heat insulation material or cold protection material. In order to reduce the weight of thermal clothing, there is no other way but to use a lightweight thermal insulation material.In consideration of the above, the present invention ignores the type of thermal insulation material. By preventing the release of trapped air as much as possible, the heat retention effect is significantly improved, and notification performance is also ensured.

■ We will aim to achieve better heat retention than before and reduce the amount of heat insulating material used.

■ We aim to reduce the weight of thermal clothing by reducing the amount of heat insulating material, and provide highly economical thermal clothing.

The above are the problems and objects that the present invention aims to solve.

(2) Regarding the structure of the invention The present application was invented based on the above object, and the structure will be explained next with reference to the drawings which are embodiments.

In this invention, an aluminum foil film 3 which is flexible and has a large number of micropores 2 is spread between the heat insulators 1 and the heat insulator 1 with a planar spread of the entire heat insulator. The structure is such that the heat insulating material 1 and the aluminum foil film 3 are covered and sewn with a fabric 4. 5 is the seam sewn appropriately.

(3) Actions and effects of the invention Next, the actions and effects of the invention will be explained with reference to the drawings which are embodiments.

1 and 3 show the case where the present invention is applied to a futon, where F is a comforter and F' is a futon.

Figure 1 (4) is a plan view of the comforter F, B is its top view, and C is a sectional view taken along line A-A of Figure 1. It is composed of a heat insulating material 1 such as feathers, and the air warmed by body temperature and expanded warms the human body (thermal insulation) by forming oil in the heat insulating material 1. It is desirable that the heat insulating material 1 has the property of retaining the air inside the heat insulating material 1 for as long as possible and preventing it from escaping to the outside air.

However, the heat insulating material 1 conventionally used for bedding etc. is cotton,
If the hot water collection effect is to be further enhanced using feathers or the like, there is no other way than to use more of each type of heat insulating material 1 to completely prevent air from escaping.

However, in the case of non-invention, for example, when a human 6 sleeps on a mattress F' and covers a quilt F as shown in FIG. The air in the insulation material 1 is warmed by the body temperature from the heat insulation material 1, and in the case of the comforter F, the flowing air rises between the fibers of the insulation material 1 (the air inside the insulation material causes a heat conduction phenomenon due to slow convection. ). In the case of the mattress F', the air in the heat insulating material 1 is heated by conduction and radiation of body temperature.

In the case of a conventional futon, the heat in the heat insulating material 1 generated by conduction, radiation, and convection will eventually flow from the surface of the fabric 40 to the futon F,
However, in the case of the present invention, since the aluminum foil film 3 is spread between the heat insulators 10, the air in the heat insulator 1 that is closer to the human body is heated more quickly.
In the comforter F, the aluminum foil film 3 prevents the heat from rising, and the aluminum foil film 3 also reflects the heat toward the human body. Since the thickness is approximately half of the entire futon F, heat conduction due to air convection in the heat insulating material 1 occurs rapidly, and therefore the temperature in the heat insulating material 1 rises rapidly.

Next, the air in the heat insulating material 1 above the aluminum foil film 3 warms as the aluminum foil film 3 warms, and the warm air below rises and passes through the micro holes 2 formed in the aluminum foil film 3. It has the effect of warming the air in the heat insulating material 1 of the section.

In addition, in the mattress F', the air in the heat insulating material 1 between the upper part of the aluminum foil film 3 and the human body 6 warms up more quickly by radiation and conduction of body temperature, and the aluminum foil film 3 on the other hand reflects heat toward the human body. Since it also has a function, the temperature of the air in the heat insulating material 1 above the aluminum foil film 3 rises more rapidly than the temperature of the air in the heat insulating material 1 below. It does not require much explanation that the temperature of the air in the lower heat insulating material 1 rises slowly as the temperature of the aluminum foil film 3 rises.

Next, while sleeping, a lot of moisture is released from the human body, and this moisture naturally passes through the micropores 2 of the aluminum foil film 3, passes through the upper heat insulating material 1, and is released into the air through the futon fabric 4.

The above is the first embodiment of the present invention, but when the present invention is applied to winter clothing, the air in the heat insulating material 1, which is closer to the skin of the human body 6 with the aluminum foil film 3 as a boundary, is heated more quickly. The first embodiment and its operation are the same. Furthermore, even if cold air from outside the body enters the winter clothing, it is temporarily blocked by the aluminum foil film 3, and in combination with the above-mentioned heat retention effect, the cold protection and heat retention effects are greatly enhanced.

The present invention provides a lume 3 having the following functions.
The aluminum foil film 3 blocks the conduction movement of the air warmed by body temperature to the next layer of heat insulating material 1, and the air in the heat insulating material 1 between the human body and the aluminum foil film 3 Warms quickly.

Because of this, the conduction speed is slow, and therefore it takes a long time for the mixed heat to be released from the surface of the clothing, so the thermal clothing of the present invention can be said to have an outstanding heat retention effect.

Furthermore, since the aluminum foil film 3 has countless micropores 2, it has appropriate notification properties and moisture is sufficiently released. It should be noted that heat conduction to the next layer of heat insulating material through the micropores 2 is also carried out to some extent. This is an explanatory diagram of the film. FIG. 3 shows the heat retention according to the present invention.

Furthermore, by spreading the aluminum foil film 3 between the heat insulators 1, it is possible to hasten the temperature rise in the heat insulators and at the same time slow down the rate of heat dissipation, so it is possible to use a smaller amount of the heat insulators 1 than before. (Savings on insulation material.) There is no reduction in the insulation effect.

Furthermore, even if the amount of heat insulating material is reduced, the heat insulating effect is still that of a dog, so there is an advantage that the weight of heat insulating clothing such as bedding and winter clothing can be reduced.

Next, the aluminum foil film 3 has been made flexible through special processing, so when using it, the noise peculiar to aluminum foil is low, it is soft, and there is no fear that the foil film will break even when folded. Since it is also inexpensive, it can be said to be an extremely economical thermal clothing that is lightweight and has a large heat retention effect.
