DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, specific embodiments of the present disclosure will be described. However, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily redundant and to facilitate understanding by those skilled in the art. Note that the inventors provide the accompanying drawings and the following explanations to enable those skilled in the art to fully understand the present disclosure, and do not intend to limit the subject matter described in the claims. In the following description, the same reference numerals are used for the same or similar components. (Embodiment 1)

[0011] First, the overall configuration of the cooling suit 1 (also referred to as a water-cooled cooling suit) will be described, and then each component will be described in detail. (Overall cooling suit)

[0012] Hereinafter, an outline of a cooling suit 1 according to one embodiment of the present disclosure will be described with reference to the drawings. FIG. 1A is a schematic front view of a cooling suit 1 in embodiment 1, and FIG. 1B is a schematic rear view of the cooling suit 1. As shown in FIG.

[0013] As shown in FIGS. 8A and 9A, the central axis of the cooling suit 1 (the central axis of the person) when the cooling suit 1 is worn on the person's body is defined as a center line 92. In addition, with the cooling suit 1 being worn on a person's body as a reference, the left side of the center line 92 is defined as the left side, and the right side is defined as the right side. In addition, based on the state in which the cooling suit 1 is worn on a person's body, the side closest to the person's body is defined as the inside, and the side farthest from the person's body is defined as the outside. In addition, with respect to when the cooling suit 1 is worn on a human body, the head side is defined as the upper side, and the foot side is defined as the lower side. In addition, the term "human body" includes both the naked state (skin alone) and the state when the person is wearing clothes.

[0014] 1A and 1B, the cooling suit 1 has an outer fabric 2 placed on the front side of the body and an inner fabric 3 placed on the rear side (back side) of the body. The cooling suit 1 has a zipper 7 at the center of the outer fabric 2 and reinforcing lines 6 that reinforce the edges. The front fabric 2 and the back fabric 3 are connected at the left and right side sides.

[0015] As shown in FIGS. 1A and 1B, the cooling suit 1 is divided into a plurality of sections (areas), allowing the user to freely select the area of ​​the body to be cooled, thereby meeting the diverse needs of users. Specifically, the cooling suit 1 is divided into a plurality of sections including a first section R1, a second section R2, a third section R3, and a fourth section R4. The first section R1, the second section R2, the third section R3, and the fourth section R4 are connected by a common fabric (such as polyester). Each of the first section R1, the second section R2, the third section R3, and the fourth section R4 is an area separated by an outer edge pressure-bonded portion 11 described later, and has a water inlet / outlet port 40, a surface layer 30, a middle layer 31, an inner layer 32, a void 12, and a water retention portion 13.

[0016] In each of the first section R1, the second section R2, the third section R3, and the fourth section R4, water is supplied to the intermediate layer 31 through the water inlet / outlet 40, and the water in the intermediate layer 31 evaporates, thereby cooling the body.

[0017] Here, a case will be considered in which water is supplied only to the first section R1, and water is not supplied to the second section R2 to the fourth section R4. In this case, the chest and back corresponding to the first section R1 are cooled, and the abdomen and lumbar region corresponding to the second section R2 to the fourth section R4 are not cooled. In this way, it is possible to meet the needs of users who do not want to cool their abdomen and lumbar region. When the user presses the front layer 30 of any one of the first compartment R1 to the fourth compartment R4, water can be drained from the water inlet / outlet port 40.

[0018] According to the above aspect, the user can cool specific areas of the body (e.g., the thorax and back) and not cool areas other than the specific areas (e.g., the abdomen and lower back), allowing the user to freely select the areas that he or she wants to cool.

[0019] Next, each component will be described in detail. (Front layer, middle layer, back layer, bonding part) FIG. 7A is a schematic cross-sectional view of the cooling suit 1 of the first embodiment, showing the cross-section taken along line AA in FIG. As shown in FIG. 7A, the outer fabric 2 has an inner layer 32 which is waterproof and disposed on the inside, an outer layer 30 which is moisture permeable and disposed on the outside, and an intermediate layer 31 made of a nonwoven fabric which is disposed between the inner layer 32 and the outer layer 30 and absorbs water and vaporizes the absorbed water by body heat.

[0020] The material of the inner layer 32 is preferably a waterproof material such as nylon. The material of the inner layer 32 may be made antistatic by using, for example, antistatic yarn such as a hydrophilic polymer. The material of the intermediate layer 31 is a nonwoven fabric, and is preferably a material such as polyurethane moisture wicking polyester fleece, technology core polyester fleece, or a fiber containing a polymer mainly composed of polyacrylic acid sodium salt and directly spun from the polymer. The material of the intermediate layer 31 is not particularly limited to the above materials, so long as it is a material that can absorb water and easily evaporate the absorbed water. The material of the front layer 30 is preferably a moisture permeable material such as 50% nylon jersey and 50% polyurethane. The material of the front layer 30 may be made antistatic by using antistatic yarn such as a hydrophilic polymer.

[0021] Flame-retardant fibers may be used for the material of the outer layer 30 and / or the material of the inner layer 32. In addition, the material of the outer layer 30 and / or the material of the inner layer 32 may be subjected to a flame retardant treatment. Examples of flame-retardant fibers and fibers that have been treated with flame retardant include Binar (registered trademark), polyetherimide (PEI) fibers, Moeny (registered trademark), Conex (registered trademark), Super Exstar (registered trademark), Anfla (registered trademark), Heim (registered trademark), Protecta (registered trademark) FR, Honoguard (registered trademark), Brevano (registered trademark), and Nonex (registered trademark).

[0022] As shown in Figures 1A and 1B, the outer edge compression portion 11 confines the intermediate layer 31 on the outer periphery of the outer fabric 2 and / or the outer periphery of the inner fabric 3, and is a linear portion where the outer layer 30 and the inner layer 32 are compressed together, and is a continuous line drawn in one stroke. A gap 12 is provided between the outer edge compression portion 11 and the intermediate layer 31 . The outer edge compression portion 11 may be in contact with the gap 12. The outer edge compression portion 11 will be described in detail with reference to Figures 4A and 4B described later.

[0023] (Water holding part) The black circles in FIGS. 1A and 1B represent water retaining portions 13. The water retaining portion 13 retains the water when it falls from the shoulders of the cooling suit 1 to the lower part of the cooling suit 1. The upper right diagram in FIG. 1A is an enlarged view of the water retaining portion 13.

[0024] FIG. 7B is a cross-sectional view taken along line BB of FIG. 1A. As shown in Figure 7B, the water retention portion 13 has a hole 10 penetrating the front fabric 2 and the back fabric 3, a pressure-bonded portion 11' in which the front layer 30 and the inner layer 32 are tightly attached around the hole 10, and a gap 12 between the front layer 30 and the inner layer 32 around the pressure-bonded portion 11'. Water is stored in gap 12 and thereby held in water holding portion 13 .

[0025] (Water injection drain) Each of the first compartment R1, the second compartment R2, the third compartment R3, and the fourth compartment R4 has a water inlet / outlet port 40. The water inlet / outlet 40 injects water into the intermediate layer 31 and drains water from the intermediate layer 31 at the same time. The water inlet / outlet 40 has a normal cap structure, and when the solid line portion of the water inlet / outlet 40 is pinched and pulled, the cap opens and the dashed line opening becomes visible. Through this opening, water can be poured into the intermediate layer 31 and water can be drained from the intermediate layer 31 at the same time.

[0026] The water inlet / outlet port 40 may be configured with a hook-and-loop fastener such as Velcro (registered trademark) that prevents water from leaking out from inside the intermediate layer 31, a waterproof zipper, or a fastener.

[0027] (drainage operation) As a premise, water has already been absorbed in the intermediate layer 31 of the first section R1, the second section R2, the third section R3, and the fourth section R4. First, the cap of the water inlet / outlet 40 is opened. Next, for example, the cooling suit 1 is placed on a desk, and the user begins to roll up the lower portion of the cooling suit 1. This causes the water in the intermediate layers 31 of the second section R2, the third section R3, and the fourth section R4 to move upward, and the water in the intermediate layers 31 is discharged from the water inlet / outlet 40. Next, when drainage of water from the second compartment R2, the third compartment R3, and the fourth compartment R4 is almost complete, the caps on the water inlet / outlet ports 40 of the second compartment R2, the third compartment R3, and the fourth compartment R4 are closed. Next, when the cooling suit 1 is further rolled up, the water in the intermediate layer 31 in the first section R1 moves upward and is discharged from the water inlet / outlet port 40. Finally, when drainage of the water from the first compartment R1 is almost complete, the cap of the water inlet / outlet 40 of the first compartment R1 is closed.

[0028] By the above operation, the water in the intermediate layer 31 is drained, and water can be poured in through the water inlet / outlet port 40. If water can be repeatedly poured in and drained, water can be supplied to the cooling suit 1 any number of times (for example, four times a day), and the cooling suit 1 can cool the body.

[0029] According to the above aspect, the user can cool the body in a specified area (e.g., the thorax and back) and not cool areas other than the specified area (e.g., the abdomen and lower back), allowing the user to freely select the area that he or she wishes to cool.

[0030] (Embodiment 2) In embodiment 2, each of the first compartment R1, the second compartment R2, the third compartment R3, and the fourth compartment R4 is provided with a water inlet 20 for injecting water into the intermediate layer 31 and a drain outlet 21 for draining water from the intermediate layer 31. FIG. 2A is a front view showing a schematic configuration of a cooling suit 101 in accordance with a second embodiment, and FIG. 2B is a rear view showing a schematic configuration of the cooling suit 101 in accordance with the second embodiment.

[0031] 2A and 2B, a water inlet 20 is provided on the upper right side of the front fabric 2 of the first section R1 and on the upper left side of the front fabric 2 of the first section R1, and a drain outlet 21 is provided on the lower right side of the front fabric 2 of the first section R1 and on the lower left side of the front fabric 2 of the first section R1. Also, as shown in Fig. 2B, a drain outlet 21 is provided on the lower side of the back fabric 3 of the first section R1. Furthermore, a water inlet 20 is provided on the upper side of each of the second compartment R2, the third compartment R3, and the fourth compartment R4, and a water outlet 21 is provided on the lower side thereof.

[0032] According to the above embodiment, the user can roll up the cooling suit 101 from the top, as is normally done, and drain water from the drain outlets 21 arranged on the underside of each section of the cooling suit 101.

[0033] When the cooling suit 101 is worn on the body, water is supplied to the intermediate layer 31 from the water inlet 20 located on the upper side of the cooling suit 101. If a large amount of water is supplied, water may accumulate below the first section R1, the second section R2, the third section R3, and the fourth section R4. In this case, the accumulated water can be drained by opening the drain outlets 21 arranged on the lower sides of the first compartment R1, the second compartment R2, the third compartment R3, and the fourth compartment R4.

[0034] FIG. 3 is a rear view showing a schematic configuration of another cooling suit 102 in the second embodiment. The length of the back fabric 3 of the cooling suit 102 is longer than the length of the back fabric 3 of the cooling suit 101 in the first embodiment. According to the above embodiment, in addition to the chest, abdomen and back, the lumbar region and buttocks can be cooled. The water inlet 20 may be constituted by a hook-and-loop fastener such as Magic Tape (registered trademark) that prevents water from leaking out from inside the intermediate layer 31, a waterproof zipper, or a fastener.

[0035] (Embodiment 3) In the third embodiment, a region for storing water is further provided in the cooling suit 101 of FIGS. 2A and 2B, and the body can be cooled for a longer period of time than in the first embodiment. FIG. 4A is a front view showing a schematic configuration of a cooling suit 103 in accordance with the third embodiment, and FIG. 4B is a rear view showing a schematic configuration of a cooling suit 1 in accordance with the third embodiment.

[0036] As shown in Figures 4A and 4B, similarly to embodiment 1, the outer edge compression portion 11 is basically a continuous line drawn in one stroke on the outer periphery of the outer fabric 2 or the outer periphery of the inner fabric 3, which adheres the outer layer 30 and the inner layer 32 to each other.

[0037] Specifically, the outer edge compression portion 11 has a right outer side compression portion 11A (outer edge compression portion 11A), a left outer side compression portion 11C (outer edge compression portion 11C), a back neck side compression portion 11B (outer edge compression portion 11B), and a back side compression portion 11D (outer edge compression portion 11D). The right front side crimping portion 11A (outer edge crimping portion 11A) has a right front side first crimping portion 11A1 (outer edge crimping portion 11A1), a right front side second crimping portion 11A2 (outer edge crimping portion 11A2), and a right front side third crimping portion 11A3 (outer edge crimping portion 11A3). The left front side pressure-bonded portion 11C (outer edge pressure-bonded portion 11C) has a left front side first pressure-bonded portion 11C1 (outer edge pressure-bonded portion 11C1), a left front side second pressure-bonded portion 11C2 (outer edge pressure-bonded portion 11C2), and a left front side third pressure-bonded portion 11C3 (outer edge pressure-bonded portion 11C3). The back underside compression portion 11D (outer edge compression portion 11D) has a back underside first compression portion 11D1 (outer edge compression portion 11D1), a back underside second compression portion 11D2 (outer edge compression portion 11D2), and a back underside third compression portion 11D3 (outer edge compression portion 11D3).

[0038] In this case, the uppermost part of the first pressure-bonding part 11A1 on the right front side and the uppermost part of the third pressure-bonding part 11D3 on the back rear side are defined as a joint part P1 based on the state in which the cooling suit 103 is worn by a person. At the joint part P1, the uppermost part of the first pressure-bonding part 11A1 on the right front side and the uppermost part of the third pressure-bonding part 11D3 on the back rear side are connected. The joint between the top of the right front third pressure-bonding portion 11A3 and the end of the back neck pressure-bonding portion 11B is defined as a joint P2. The joint between the top of the left front side first pressure-bonding portion 11C1 and the end of the back neck pressure-bonding portion 11B is defined as a joint P3. The top of the right front third pressure-bonding portion 11A3 and the top of the back rear first pressure-bonding portion 11D1 are defined as a joint P4. At the joint P4, the top of the left front third pressure-bonding portion 11C3 and the top of the back rear first pressure-bonding portion 11D1 are connected.

[0039] As shown in Fig. 4A, the right side fourth pressure-bonding portion 11A4 (also referred to as the inclined pressure-bonding portion 11A4) branches off from the right side third pressure-bonding portion 11A3 and is connected to the right side third pressure-bonding portion 11A3. The right side fourth pressure-bonding portion 11A4 is inclined from the upper right to the lower left of the drawing. A right side first gap 12A1 is provided between the right side first pressure-bonding portion 11A1 and the right side fourth pressure-bonding portion 11A4.

[0040] The right side fifth pressure-bonding portion 11A5 (also referred to as the inclined pressure-bonding portion 11A5) branches off from the right side first pressure-bonding portion 11A1 and is connected to the right side first pressure-bonding portion 11A1. The right side fifth pressure-bonding portion 11A5 is inclined from the upper left to the lower right of the page. A right side second gap 12A2 is provided between the right side third pressure-bonding portion 11A3 and the right side fifth pressure-bonding portion 11A5.

[0041] The outer fabric 2 of the first section R1 is divided into three areas on the right side and three areas on the left side, making a total of six areas. The three regions on the right side of the front fabric 2 of the first section R1 are a right front first region 61, a right front second region 62, and a right front third region 63. The three regions on the left side of the front fabric 2 of the first section R1 are a left front first region 65, a left front second region 66, and a left front third region 67. In each of the above regions, the intermediate layer 31 is disposed in a divided state, and each of the above compression-bonding portions surrounds the periphery of the divided intermediate layer 31 with a gap 12 therebetween. In other words, there is a gap 12 between each of the compression-bonded portions and the divided intermediate layer 31 . Incidentally, each of the pressure-bonded portions and the intermediate layer 31 may be in contact with each other.

[0042] The right front-side first region 61 is a region surrounded by the right front-side first pressure-bonded portion 11A1, the right front-side fourth pressure-bonded portion 11A4, the right front-side third pressure-bonded portion 11A3, and the upper portion (the line connecting the joint portion P1 and the joint portion P2) of the front-side fabric 2. In the right front-side first region 61, a water inlet 20 is arranged. When water is supplied to the intermediate layer 31 from the water inlet 20, the water in the right surface-side first region 61 moves from the right surface-side first region 61 to the right surface-side second region 62 through the right surface-side first gap 12A1.

[0043] 4A, the smaller the inclination angle formed by the horizontal line perpendicular to the longitudinal center line 92A of the front fabric 2 passing through the fastener 7 and the inclined pressure-bonded portion 11A4, the smaller the amount of water flowing from the right front-side first gap 12A1 can be, and therefore the longer the time that water is retained in the right front-side first region 61 can be. As a result, the body can be cooled for a longer period in the right front-side first region 61.

[0044] Using general-purpose thermal fluid analysis software using the finite volume method, the movement of water in the intermediate layer 31 in the right surface-side first region 61 and the right surface-side second region 62 including the inclined pressure-bonded portion 11A4 was analyzed. The analysis method is as follows: (1) First, place the cooling suit 1 on a horizontal desk and pour water into the water inlet 20 until the water is evenly absorbed into the middle layer 31 of the outer fabric 2. The amount of water in the middle layer 31 at this time is the maximum amount that would cause water to leak out of the middle layer 31 if any more water was poured into the middle layer 31. (2) Next, when the cooling suit 1 having the maximum amount of water in the intermediate layer 31 was stood vertically, an analysis was conducted on the change over time in the distribution of water moving from the right outer side first region 61 to the right outer side second region 62. At this time, the inclination angle formed by the horizontal line perpendicular to the center line 92A and the inclined pressure-bonding portion 11A4 was changed (from 0 degrees to 90 degrees).

[0045] The results of the above simulation will now be described. According to the above simulation, it was found that the amount of water (movement amount) moving from the right front side first region 61 to the right front side second region 62 becomes almost constant in about 10 seconds even if the inclination angle is changed. It was found that the movement amount per unit time becomes very small after about 10 seconds. If the amount of water moving from the right surface first region 61 to the right surface second region 62 after 10 seconds when the inclination angle is 90 degrees is taken as the reference (100%), (a) After 10 seconds, the amount of water movement when the inclination angle was 45 degrees was approximately 91% to 93% of the above standard. (b) After 10 seconds, the amount of water movement when the inclination angle was 0 degrees (horizontal) was approximately 83% to 86% of the above standard.

[0046] In other words, it was found that the smaller the inclination angle, the smaller the amount of water that moves from the right front side first region 61 to the right front side second region 62. It was also found that the smaller the inclination angle, the longer water accumulates in a portion of the right front side second region 62 below the inclined pressure-bonded portion 11A4 (for example, a portion under the eaves if the inclined pressure-bonded portion 11A4 is the eaves).

[0047] This is presumably due to the following reasons. The water above the inclined pressure-bonding portion 11A4 tries to move downward due to gravity, but is blocked by the inclined pressure-bonding portion 11A4. Therefore, the water below the inclined pressure-bonding portion 11A4 is not subjected to the pressure of the water above the inclined pressure-bonding portion 11A4, and remains in the right front side second region 62 below the inclined pressure-bonding portion 11A4. Therefore, the smaller the inclination angle, the longer the water can be retained in the intermediate layer 31. On the other hand, when the upper part of the cooling suit 1 is rolled up to drain water through the drain outlet 21, the larger the inclination angle, the greater the amount of water flowing through the gap 12A1, and therefore the water can be drained smoothly through the drain outlet 21. Based on the above simulations, it has been found that the inclination angle is preferably 1 degree or more and 45 degrees or less, and more preferably 2 degrees or more and 15 degrees or less. The same can be said about each of the following inclined compression sections.

[0048] The right side second region 62 is a region surrounded by the right side first pressure-bonded portion 11A1, the right side fifth pressure-bonded portion 11A5 (the inclined pressure-bonded portion 11A5), the right side third pressure-bonded portion 11A3, and the right side fourth pressure-bonded portion 11A4 (the inclined pressure-bonded portion 11A4). In the right side second region 62, the water retaining portion 13 is arranged. The water in the right surface-side second region 62 moves from the right surface-side second region 62 to the right surface-side third region 63 through the right surface-side second void 12A2. The inclination angle of the inclined pressure-bonding portion 11A5 is similar to that of the inclined pressure-bonding portion 11A4.

[0049] The right front-side third region 63 is a region surrounded by the right front-side first pressure-bonded portion 11A1, the right front-side second pressure-bonded portion 11A2, the right front-side third pressure-bonded portion 11A3, and the right front-side fifth pressure-bonded portion 11A5. A drain outlet 21 is arranged in the right front side third region 63.

[0050] According to the above embodiment, when water is supplied to the intermediate layer 31 from the water inlet 20 and the right-side front fabric 2 is pressed by a human hand, the water passes through the right-side first void 12A1 and the right-side second void 12A2, and can be stored in the right-side first region 61, the right-side second region 62, and the right-side third region 63. As a result, the above embodiment can cool the body for a long period of time.

[0051] Since the right outer side first region 61 has an inclined pressure-bonded portion like the inclined pressure-bonded portion 11A4, the time for which water is retained in the right outer side first region 61 can be extended, and when the upper part of the cooling suit 1 is rolled up to drain water from the drain outlet 21, the water can be easily pushed downward. The same can be said about the right front second region 62 as about the right front first region 61 . Although the right side of the front fabric 2 of the first section R1 is configured with three stages, namely, the right front first region 61, the right front second region 62, and the right front third region 63, it is sufficient that the right fabric 2 has at least two stages.

[0052] As shown in FIG. 4A, when viewed from the front, the configuration of the right side of the front fabric 2 and the configuration of the left side of the front fabric 2 are symmetrical with respect to the center line 92A. Therefore, a description of the configuration of the left side of the front fabric 2 will be omitted.

[0053] As shown in Fig. 4B, when viewed from the back, the back underside fourth pressure-bonded portion 11D4 (referred to as the inclined first pressure-bonded portion 11D4) is inclined from the upper right to the lower left of the paper surface, starting from the center line 92B (the center line 92B in this case is a line obtained by projecting the center line 92B in Figs. 8A and 8B onto the back fabric 3). Between the back underside first pressure-bonded portion 11D1 and the back underside fourth pressure-bonded portion 11D4, there is a back underside first gap 12D1. The back side fifth compression portion 11D5 (referred to as the inclined second compression portion 11D5) is inclined from the upper left to the lower right of the paper starting from the center line 92B. Between the back side third compression portion 11D3 and the back side fifth compression portion 11D5, there is a back side third gap 12D3.

[0054] The first inclined pressure-bonding portion 11D4 and the second inclined pressure-bonding portion 11D5 are formed in a mountain shape. The apex (imaginary apex) of the mountain shape passes through the center line 92B, and the mountain shape is symmetrical with respect to the center line 92B. A back second gap 12D2 is provided between one end (on the center line 92B side) of the first inclined compression portion 11D4 and one end (on the center line 92B side) of the second inclined compression portion 11D5 (near the imaginary apex). One end (on the side of the center line 92B) of the first inclined pressure-bonding portion 11D4 and one end (on the side of the center line 92B) of the second inclined pressure-bonding portion 11D5 may be connected to each other without having the back-side second gap 12D1.

[0055] The back fabric 3 is divided into two regions: a back first region 71 and a back second region 72. The back side first region 71 is an area surrounded by the back side first pressure-bonded portion 11D1, the back side fourth pressure-bonded portion 11D4, the back side fifth pressure-bonded portion 11D5, the back side third pressure-bonded portion 11D3, and the upper portion of the back side fabric 3. In the back side first region 71, the water inlet 20 and the water retaining portion 13 are arranged.

[0056] Since the water inlet 20 is disposed on the center line 92B in the first backside region 71, the water can be divided and flow evenly along the first inclined pressure-bonded portion 11D4 and the second inclined pressure-bonded portion 11D5. When water is supplied to the intermediate layer 31 from the water inlet 20 and the back fabric 3 is pressed by a human hand, the water passes through the back first gap 12D1, the back second gap 12D2, and the back third gap 12D3, and moves from the back first region 71 to the back second region 72 described later. Since water can move from the first back region 71 to the second back region 72 from both sides and the center of the back fabric 3, water can be distributed uniformly to the intermediate layer 31 in the second back region 72.

[0057] 4B, the smaller the inclination angle formed by the horizontal line perpendicular to the longitudinal center line 92B of the back fabric 3 and the inclined pressure-bonded portion 11D4, the smaller the amount of water flowing from the back back first gap 12D1, and the longer the time that the water is retained in the back first region 71. As a result, the body can be cooled for a long time in the back first region 71. On the other hand, when the upper part of the cooling suit 1 is rolled up to drain water through the drain outlet 21, the larger the inclination angle, the more water can flow from the first gap 12D1 on the back side, and therefore the water can be drained smoothly through the drain outlet 21. Based on the above simulation, the inclination angle is preferably from 1 degree to 45 degrees, and more preferably from 2 degrees to 15 degrees. The same can be said for each inclined crimping portion of 11D5 and the like.

[0058] The back side second region 72 is an area surrounded by the back side first pressure-bonded portion 11D1, the back side second pressure-bonded portion 11D2, the back side third pressure-bonded portion 11D3, the back side fifth pressure-bonded portion 11D5 (the inclined second pressure-bonded portion 11D5), and the back side fourth pressure-bonded portion 11D4 (the inclined first pressure-bonded portion 11D4). In the back side second region 72, the water retaining portion 13 and the drainage port 21 are arranged.

[0059] The drain outlet 21 is disposed at the lower left side of the second rear region 72. When the upper part of the cooling suit 1 is rolled up, water flows out from the back first gap 12D1 arranged on the left side, so that the water can be quickly discharged from the drain outlet 21 close to the back first gap 12D1. The drain hole 21 may be disposed at the lower right side of the back fabric 3.

[0060] According to the above embodiment, water is supplied to the middle layer 31 of the back fabric 3 from the water inlet 20 of the front fabric 2 or the back fabric 3, and when the back fabric 3 is pressed with a human hand, the water can be distributed through the back first back gap 12D1, the back second back gap 12D2, and the back third back gap 12D3 to the back first region 71 and the back second region 72. As a result, the above embodiment can cool the body for a long period of time. Furthermore, by rolling up the upper part of the cooling suit 1, water can be discharged smoothly from the drain outlet 21.

[0061] In addition, the first section R1, the second section R2, the third section R3, and the fourth section R4 may each have one or more oblique compression portions. Although the back side first region 71 and the back side second region 72 are divided into two regions by the mountain-shaped inclined first pressure-bonding portion 11D4 and the inclined second pressure-bonding portion 11D5, the back side may be divided into three or more regions by multiple mountain-shaped inclined pressure-bonding portions. In the second section R2, the third section R3 and the fourth section R4, the inclined compression portion may be one or more. Although the back fabric 3 is provided with the obliquely pressed portion having a mountain shape, the front fabric 2 may be provided with the obliquely pressed portion having a mountain shape.

[0062] Although the right-side fourth pressure-bonding portion 11A4 and the right-side third pressure-bonding portion 11A3 are connected, a gap may be provided between the right-side fourth pressure-bonding portion 11A4 and the right-side third pressure-bonding portion 11A3. In the above case, the gap satisfies at least one or more of the following conditions. (Condition 1) When water is supplied from the water inlet 20 of the cooling suit 1 and a person is wearing the cooling suit 1, the water accumulates in the right-side first area 61, and in the right-side first area 61, the water level is above the gap. If the outer fabric 2 of the right-side first area 61 is not pressed by a person's hand, water will not move from the right-side first area 61 (upper area) to the right-side second area 62 (lower area) through the gap. (Condition 2) When water is stored in the right-side first region 61 and the front fabric 2 of the right-side first region 61 is pressed with a human hand, the water can move from the right-side first region 61 to the right-side second region 62 through the gap.

[0063] Similarly, gaps may be provided in the connection portion between the right front side first crimping portion 11A1 and the right front side fifth crimping portion 11A5, the connection portion between the left front side first crimping portion 11C1 and the left front side fourth crimping portion 11C4, and the connection portion between the left front side first crimping portion 11C3 and the back side fifth crimping portion 11C5.

[0064] (Embodiment 4) In the fourth embodiment, four radiative cooling materials 85 are placed over the first section R1, the second section R2, the third section R3, and the fourth section R4 of the cooling suit 1 of the first embodiment. FIG. 5A is a front view showing a schematic configuration of the radiative cooling material 85 in embodiment 4, and FIG. 5B is a rear view showing a schematic configuration of the radiative cooling material 85 in embodiment 4.

[0065] The radiative cooling material 85 is divided into a first radiative cooling material (H1), a second radiative cooling material (H2), a third radiative cooling material (H3), and a fourth radiative cooling material (H4), corresponding to the first section R1, the second section R2, the third section R3, and the fourth section R4. In Figures 5A and 5B, the inner outer edge compression portion 11 of the radiative cooling material 85 is diagrammatically depicted by a dashed line.

[0066] The radiative cooling material 85 is a material that utilizes the principle of "radiative cooling" to lower the temperature of the radiative cooling material 85 and the environmental temperature in the shade on the opposite side of direct sunlight (hereinafter referred to as the shadow temperature) without using energy by releasing heat into space even under direct sunlight. For example, Radi-Cool fabric manufactured by Radi-Cool Japan Co., Ltd. can be used as the radiative cooling material 85. Depending on the sunlight conditions, the shadow temperature of Radicourt fabric can be about 10 to 20 degrees Celsius lower than the shadow temperature of ordinary fabrics.

[0067] Each of the first radiative cooling material (H1), the second radiative cooling material (H2), the third radiative cooling material (H3), and the fourth radiative cooling material (H4) has a space on the cooling suit 1 and is fixed by a fixing member 86. The top left image in FIG. 5A is an enlarged side view of the peripheral area of ​​the fixing member 86. The fixing member 86 includes a spacer 87 and a pin 88 . The spacer 87 is provided on the surface of the cooling suit 1, and has a spacer hole 95. The pin 88 is made of rubber, and has a head portion 93 and a protrusion 94.

[0068] Each of the first radiative cooling material (H1), the second radiative cooling material (H2), the third radiative cooling material (H3), and the fourth radiative cooling material (H4) has a radiative cooling material hole 91. The protrusion 94 of the pin 88 penetrates the radiative cooling material hole 91, and the protrusion 94 fits into the spacer hole 95, so that the radiative cooling material 85 is fixed to the cooling suit 1 with a space. On the other hand, since the pin 88 can be removed from the spacer hole 95, the first radiative cooling material (H1), the second radiative cooling material (H2), the third radiative cooling material (H3), and the fourth radiative cooling material (H4) can be removed from the cooling suit 1 by removing the pin 88 from the spacer hole 95. In addition, the user can select the radiative cooling material 85 that he / she wants to remove and remove it from the cooling suit 1 freely. The cooling suit 1 and the radiative cooling material 85 may be in partial contact with each other.

[0069] The top right image in FIG. 5A is an enlarged view of the left lateral side. There is a space between the front fabric 2 of the cooling suit 1 and the radiative cooling material 85. Water vapor generated by evaporation from the intermediate layer 31 of the cooling suit 1 passes through the space and is released to the outside. Even if direct sunlight hits the radiative cooling material 85, the shadow temperature is reduced by the radiative cooling material 85, so the temperature rise of the water held in the intermediate layer 31 of the cooling suit 1 due to direct sunlight is suppressed. Therefore, the amount of water vapor released from the intermediate layer 31 into the space is reduced, so that the body can be cooled for a long period of time. The back fabric 3 in FIG. 5B has the same structure as the front fabric 2 in FIG. 5A.

[0070] According to the above embodiment, a space is provided between the radiative cooling material 85 and the cooling suit 1, the shadow temperature is lowered by the radiative cooling material 85, and the amount of water vapor released into the space from the intermediate layer 31 is reduced, so that the body can be cooled for a long period of time. In addition, the user can select any radiative cooling material 85 and remove the radiative cooling material 85 from the cooling suit 1.

[0071] FIG. 6 is a front view showing a schematic configuration of another radiative cooling material 85 in the fourth embodiment. As shown in FIG. 6, the radiative cooling material 85 covers the entire surface of the cooling suit 1. The radiative cooling material 85 is made of a single piece of material and has a head hole for inserting a human head therethrough and a radiative cooling material hole 91.

[0072] A method for attaching the radiative cooling material 85 to the cooling suit 1 will now be briefly described. The user puts his / her head through the head hole of the radiative cooling material 85. Then, the user puts a pin through the radiative cooling material hole 91 arranged on the shoulder, and fastens the pin 88 to the spacer hole 95, so that the radiative cooling material 85 can be easily attached to the cooling suit 1.

[0073] (Embodiment 5) 8A and 8B are schematic perspective views of the cooling suit 1 of embodiment 1 in embodiment 5 layered on top of an air-conditioning suit 50 (also called Air-Conditioning Fuujin Suit (registered trademark) or Air-Conditioning Suit (registered trademark)). As described in Japanese Utility Model Publication No. 3-32487 and Japanese Patent Publication No. 6,536,674, air-conditioning clothing 50 is clothing equipped with a fan 51 that blows outside air into the clothing, promoting the evaporation of sweat from the body and lowering the body temperature.

[0074] The operation of layering the cooling suit 1 and the air-conditioning suit 50 will now be described. First, as shown in FIG. 8A, the cooling suit 1, which has already been filled with water, is put on the body and the zipper 7 is fastened. Next, as shown in FIG. 8B, the air-conditioning suit 50 is put on over the cooling suit 1, and the zipper 7 of the air-conditioning suit 50 is fastened. Finally, the fan 51 of the air-conditioning clothing 50 is rotated to send outside air into the inside of the clothing. The combination of the layered cooling suit 1 and the air-conditioning suit 50 is called a cooling suit set.

[0075] According to the above embodiment, the air-conditioning suit 50 sends outside air to the surface of the cooling suit 1, accelerating the evaporation of water in the cooling suit 1 and enabling the body temperature to be lowered quickly. Although the fan 51 is rotated after putting on the air-conditioning suit 50, the air-conditioning suit 50 with the fan 51 rotating may be put on over the cooling suit 1.

[0076] 9A and 9B are another embodiment variation of FIGS. 8A and 8B. In a modified example, as shown in FIG. 9A, the cooling suit 1 is worn inside out (reverse) on the body. The subsequent operation of layering the cooling suit 1 and the air-conditioning suit 50 is similar to that shown in FIG. 8B, and therefore will not be described.

[0077] According to the above embodiment, the front layer 30 of the front fabric 2 and the front layer 30 of the back fabric 3 of the cooling suit 1 are positioned closest to the body, so that the water in the intermediate layer 31 can pass through the front layer 30 and evaporate to lower body temperature without the person sweating. Furthermore, the air-conditioning suit 50 sends outside air into the cooling suit 1, accelerating the evaporation of water in the cooling suit 1 and enabling the body temperature to be lowered quickly.

[0078] The water inlet 20 or the drain outlet 21 of the first embodiment may be configured with the cap of the third embodiment.

[0079] The drain hole 21 may be formed of a Velcro tape (registered trademark), a waterproof zipper, or a fastener, which prevents water from leaking out from inside the intermediate layer 31.

[0080] The above-mentioned aspects of the present invention can be replaced or combined as long as no contradiction occurs.
