Description

TECHNICAL FIELD The present invention relates to a sensible cooling upper garment capable of suitably cooling the wearer's body.

2. Description of the Related Art In recent years, due to global warming, the temperature in summer has risen remarkably, and heatstroke caused by working or exercising at high temperatures has become a problem. Heatstroke is a symptom in which the function of the hypothalamus to maintain a normal body temperature is reduced, and the sweating action of the whole body is stopped, resulting in an excessive rise in body temperature.

Various techniques for cooling have been devised in order to provide a comfortable environment as a countermeasure against heatstroke as described above. For example, in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2008-260213), a nonwoven fabric made of polyester fiber and/or polyamide fiber and a thermoplastic polyurethane resin layer have low permeability for the purpose of protecting hands and feet and keeping warm and moist. A low-moisture-permeable laminate integrated by lamination via a wet resin layer has been proposed.

On the other hand, for example, in Patent Document 2 (International Publication No. 02/067708 pamphlet), for the purpose of providing a cooling garment which has a simple structure and which can be worn comfortably, there is a gap between the cloth part and the body when the garment is worn. one or more spacers for securing an air flow passage, an air inlet portion for taking in outside air into the flow passage, and an air outlet portion for extracting the air in the flow passage to the outside , and blowing means for forcing a flow of air in the flow channel.

JP 2008-260213 A WO 02/067708 Pamphlet

However, in the laminate proposed in Patent Document 1, since the nonwoven fabric is exposed to the skin side, it may contain more moisture than expected, which may increase discomfort. Although it is easy to apply, it is difficult to dry, and sufficient heat of vaporization may not be obtained, so it is difficult to apply it to clothes as it is.

On the other hand, the air-conditioned clothing proposed in Patent Document 2 above has a structure in which external air is generally drawn into the clothing, and most of the drawn-in air stays inside the clothing, resulting in a sufficient cooling effect. sometimes not.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a sensory cooling upper garment that allows the wearer to experience a sufficient cooling effect by more reliably and accurately utilizing the heat of vaporization of moisture.

The injection port 16 of this embodiment employs the same mechanism as Ziploc (registered trademark), and can be easily opened by lifting the downward tab portion with a fingertip as shown in FIG. 1(B). It can be closed watertight by pressing the whole.

(2) Regarding the cooling structure As described above, in the jacket 1 of the present embodiment, the inside of the back body 4 and the inside of the front body 2 are seamlessly connected at the side edges. A single cooling structure 6 is mounted inside the right front body 2R and the left front body 2L of the front body 2 throughout. This attachment may be made by, for example, heat sealing, high frequency welding, or an adhesive. In addition, each of the front body 2 and the back body 4 may be a bag-like body having a gap formed of two sheets of the same fabric, in which case the cooling structure 6 is built in the gap. can also

Here, FIG. 3 is a schematic cross-sectional view showing the structure of the cooling structure 6 incorporated in the body cooling jacket 1 shown in FIG. 1, and FIG. 4 is a schematic front view of the cooling structure 6 shown in FIG. 4A) and a schematic front view (B) of a water-retaining core material 6a included in the cooling structure 6. FIG.

As shown in FIG. 3, the cooling structure 6 is composed of a water-retaining bag 6b whose both sides are made of a sheet-like moisture-permeable waterproof material, and a water-retaining core material 6a inserted inside the water-retaining bag 6b. there is The moisture-permeable waterproof material on the front side and the moisture-permeable waterproof material on the back side are water-tightly joined at the periphery by heat sealing, high-frequency welding, adhesive, etc., and there is a gap inside which the water-retaining core material 6a can be built. Water is injected (supplied) into the gap and the water-retaining core material 6a.

The cooling structure 6 in this embodiment can be said to have a substantially W shape, as shown in FIG. It has a shape extending to the right front body 2R and the left front body 2L. It also has an opening 16 a that communicates with an inlet 16 provided above the back body 4 to guide water into the interior of the cooling structure 6 .

As shown in FIG. 4B, the water-retaining core material 6a incorporated in the cooling structure 6 has a shape similar to that of the cooling structure 6 but has slightly smaller dimensions. By having such a shape, the water-retaining core material 6a is less likely to be displaced inside the cooling structure 6, and the cooling structure 6 is positioned in the upper garment 1 (the back body 4 and the front body 2). It is difficult to cause deviation.

In this embodiment, as shown in FIG. 4(B), the water-retaining core material 6a is provided with circular openings (holes) 20 formed by, for example, Thomson punching or the like so as to more reliably retain the injected water. are formed by arranging regularly in a bilaterally symmetric manner.

In addition, as shown in FIG. 4A, the moisture-permeable waterproof material located on the outer surface of the cooling structure 6 (water-retaining bag 6b) is subjected to high-frequency heat welding or the like at the circular portion (welding portion) indicated by reference numeral 16b. may be joined to the front body 2 and the back body 4 by Also, the moisture-permeable waterproof material may be joined to the internal water-retaining core material 6a by high-frequency heat welding or the like at the circular portion (welded portion) indicated by reference numeral 16b.

Such bonding also prevents the cooling structure 6 from being displaced inside the jacket 1 (the back body 4 and the front body 2), and the water-retaining core material 6a is not displaced inside the cooling structure 6. You can enjoy the advantage that it is difficult to cause

Both the cooling structure 6 and the water-retaining core material 6a may have various shapes as long as the effects of the present invention are not impaired. In addition, as shown in FIG. 4A, the outer peripheral edge of the cooling structure 6 (water retaining bag 6b) of the present embodiment has a striking portion, which is not visible on the front side. It can be attached to or built into the Also, the hitting part can be omitted.

Here, both sides of the water retention bag 6 that constitutes the cooling structure 6 are formed of a moisture-permeable waterproof material that allows only water vapor to permeate without permeating water. Demonstrate waterproof function. By accumulating water inside the water retaining bag 6b, the water inside can only pass through the moisture-permeable waterproof material as water vapor, so the inside and outside of the jacket 1 are not wetted, and the water inside evaporates and evaporates. It is possible to reduce the sensible temperature by, for example, about 1 to 5°C by removing heat.

When the user wears the jacket 1, if water is present inside the water-retaining bag 6b and the water is moved freely or the position is biased, the feeling of wearing is hindered or the part where the cooling can be felt is biased. However, in the present embodiment, since the water-retaining core material 6a is built in, water is absorbed and retained therein, and this problem is resolved.

As the water-retaining core material 6a, cloth such as woven fabric, non-woven fabric, or knitted fabric, sponge-like sheet, or the like made of various materials can be used as long as they have a water-retaining function. Examples of materials include polyester, nylon (polyamide), urethane, rayon and cotton.

The moisture permeability of the moisture-permeable waterproof material can be set in various ranges as long as the effects of the present invention are not impaired, but is preferably 3000 g/m ² ·24 hours or more, for example. This moisture permeability is measured according to condition B of JIS Z 0208 "Testing method for moisture permeability of moisture-proof packaging materials (cup method)". If it is 3000 g/m ² ·24 hours or more, the water vapor in the water retention bag 6 can be sufficiently permeated. Also, by changing the moisture permeability of the moisture-permeable and waterproof material, it can be used for various purposes.

Also, the water pressure resistance of the moisture-permeable waterproof material can be set in various ranges as long as the effects of the present invention are not impaired. This is preferable because water can be reliably retained in the water retaining bag 6 .

As the moisture-permeable and waterproof material, a conventionally known material can be used, but it is selected within a range that does not impair the effect of the present invention that the cooling due to the heat of vaporization of the supplied water is felt more reliably. For example, Sofande (registered trademark) manufactured by Asahi Kasei Corporation, Aquamax (registered trademark) manufactured by Seiren Co., Ltd., Ami Shelter, Technobrane (registered trademark), Silent Shell, Barrel (registered trademark) and Barrel (registered trademark) ) · Green, Fine Cell (registered trademark), Natural Barrier (registered trademark), Rectus (registered trademark) and Delta (registered trademark) manufactured by Teijin Limited, Entrant (registered trademark) and Dermisax (registered trademark) manufactured by Toray Industries, Inc. registered trademark) and Proof Ace (registered trademark) manufactured by Unitika Ltd., and the like.

(3) Air-conditioning fan FIG. 5 is a schematic diagram showing a state in which air-conditioning fans 18 are provided in the left and right lower portions of the back body 4 of the body cooling jacket 1 shown in FIG. 1(B). Air conditioning fans 18 can be detachably attached to the left and right lower portions 10R and 10L of the back body 4 of the jacket 1 of this embodiment.

Although not shown here, substantially circular through-holes for air-conditioning fan mounting are formed in the left and right lower portions 10R and 10L of the back body 4 to communicate the outside and the inside of the jacket 1 with each other. However, although the external shape of the air-conditioning fan 18 is usually cylindrical, if it has another shape, the shape of the hole may be appropriately selected according to the shape. A relatively thick ring-shaped cloth having a hole in the center may be attached to the edge of the air-conditioning fan mounting hole to improve the strength.

When the jacket 1 of this embodiment is equipped with an air-conditioning fan 18, air from the outside is drawn in from the left and right lower portions of the back body 4, and an air current is generated and circulated inside the jacket 1 to perform air conditioning. be able to. When the air-conditioning fan 18 rotates, external air is drawn into the upper garment 1, and the air is gradually directed upward and forward (between the front body 2 and the body) while widening the gap between the wearer's body and the upper garment 1. let it fill.

When the inside of the upper garment 1 is filled with a certain amount of air, it is released to the outside from the neck (and the gap between the user) and the air-permeable areas around the armholes 12R and 12L, mainly for the back muscles. It can prevent heat buildup by forming an air current that flows from the bottom to the top. Since the vicinity of the back muscles is a part where the wearer can feel a particularly cold sensation, it is possible to obtain a high cooling effect.

At this time, if the airflow path is formed by arranging the air-permeable convex portions 8 on the inner surface side of the back body 4, the airflow flowing upward from the lower side of the back can be more reliably formed. , the heat buildup can be reliably prevented, and the cooling effect is further improved.

Although one embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to these embodiments, and is within the scope of the spirit and teachings of the description of the claims. Other refinements and variations exist. It is easily understood by those skilled in the art that all such improvements and modifications are included in the technical scope of the present invention.

This injection port 16 employs the same mechanism as Ziplock (registered trademark), and can be easily opened by lifting the downward tab shown in FIG. can be opened to In addition, in FIG. 6(B), linear portions that engage with each other for sealing appear.

In this embodiment, since water is injected into the cooling structure 6 from around the upper end portion of the back body 4 , water is easily supplied to the entire cooling structure 6 . On the other hand, inlets may be provided in the left and right chest portions and armpit portions so that the user can easily supply water to the upper garment 1 while wearing it.

The sensory cooling jacket according to the present invention as described above can more reliably and accurately utilize the heat of vaporization of water to allow a user to experience a sufficient cooling effect. It is suitable for outdoor activities such as work sites, factories, festivals, fishing, fireworks and camping, sports such as walking, jogging and golf, watching sports, traveling and touring on bicycles and motorbikes, and sightseeing. In particular, it is suitable for use in an environment where wind is naturally taken in (for example, walking, jogging, traveling by bicycle or motorcycle, touring, etc.).
