FIG. 5 is a diagram for explaining a method of fixing the connection cords of the four fans.

 As shown in FIG. 1 and FIG. 4, the cooling garment of the first embodiment has a cloth material portion 10, three spacer portions 20, three air inflow portions 40, and four air outflow portions. It comprises a unit 50, four fans (blowing means) 60, four spacing securing means 80, a power supply box 90, and an air leak preventing means (not shown). In the first embodiment, a case will be described in which such a cooling garment is applied to work clothes, uniforms, and other types of clothes that are worn without putting the hem in pants. This cooling garment is a long-sleeved garment, of which the front is closed with a zipper. The cooling garment is worn over underwear. Here, in the first embodiment, clothing worn under the cooling clothing is referred to as “underwear”. For example, if you decide to wear a shirt under cooling clothing, that shirt is the “underwear” here.

 Three spacer portions 20 are sewn on the back surface of the fabric portion 10 with thread. In the first embodiment, each spacer portion 20 is sewn to a sweat-prone portion, for example, the position of the clothing portion 10 corresponding to the left chest, the right chest, and the back. The spacer portion 20 is for forming an air flow passage for allowing air to flow between the clothing portion 10 and the underwear. This space forms an air flow passage that is substantially parallel to the body surface when a person wears cooling clothing. In general, some clothes are provided with a spacer for the purpose of cushioning, etc., but even in such clothes, the spacer secures a certain space between the clothes and the underwear. If such a function is provided, the spacer is the “spacer” in the present invention.

 In the first embodiment, a fastener is used as a means for closing the front part when the cooling garment is worn. A button or hook can be used, but it is preferable to use a fastener. The fastener can be easily opened and closed, and when the fastener is closed, almost no air leaks from the fastener part to the outside. Therefore, when the fastener is closed, the two spacer portions 20 provided on the front side of the clothing material portion 10 constitute one airflow passage as a whole.

An air inflow portion 40 is formed at the position of the clothing portion 10 corresponding to the vicinity of the upper end of each spacer portion 20. The width of the air inlet section 40 is the same as that of the spacer section 20. 略 It is almost the same as the width. The air inflow portion 40 is formed, for example, by cutting out a predetermined portion of the clothing portion 10 and sewing a mesh material 41 onto the cutout portion from the back side of the clothing portion 10. . This mesh-shaped material 41 is for preventing the spacer portion 20 from jumping out and reducing the unnaturalness in the appearance of the cooling garment. External air flows into the spacer section 20 from the air inflow section 40. In the example of FIG. 1, three air inflow portions 40 are provided at the front side of the upper portion of the cloth material portion 10 and one at the rear side. It should be noted that the neck and sleeves can also be considered as air inlets in a broad sense.

 On the other hand, an air outflow portion 50 is formed at a predetermined position of the clothing material portion 10 corresponding to the lower end portion of the spacer portion 20. The air outflow portion 50 is formed in the same manner as the air inflow portion 40. That is, for example, it is formed by cutting out a predetermined portion of the clothing portion 10 and sewing a mesh-shaped material 51 to the cutout portion from the back surface side of the clothing portion 10. The mesh-like material 51 is for reducing the unnaturalness in the appearance of the cooling garment. The air in the spacer section 20 flows out of the air outflow section 50 to the outside. The number of air outlets 50 is the same as the number of fans 60. In the example of FIG. 1, four air outlets 50 are provided before and after the lower part of the cloth material part 10, that is, four in total.

 In addition, without providing such an air inflow portion 40, from a predetermined end portion of the clothing material portion 10, for example, from an open end of the spacer portion 20 (a gap between the cooling clothing and the underwear) at a neck portion, Air may be taken into the spacer section 20. In this case, it is necessary to extend the mounting position of the spacer portion 20 to a portion that takes in the air. As described above, when the open end of the spacer portion 20 at the neck portion is used as an air inflow portion, it is not necessary to provide the air inflow portion 40, so that the cooling clothes have an uncomfortable appearance. There is an advantage that the number is reduced.

The four fans 60 are provided for forcibly generating an air flow in the support section 20. The positions of the back of the cloth section 10 corresponding to the respective air outlet sections 50 are respectively provided. Attached to. In other words, two fans 60 are provided before and after the lower portion of the clothing portion 10. The fan 60 rotates in a direction to discharge the air in the spacer section 20 to the outside. When the fan 60 is rotated in this direction, it is formed by the spacer section 20 The pressure in the air flow passage decreases, and external air flows into the air flow passage from the air inflow portion 40. The inflowing air moves in the air flow passage in a direction substantially parallel to the body surface and in a direction toward the bottom. When the air reaches the fan 60, the air is sucked by the fan 60 and discharged to the outside through the air outlet 50.

 The four fans 60 are connected in parallel, as shown in FIG. 5, and the connection cord 69 is connected to the power supply box 90. The power supply box 90 contains batteries (power supply means). This battery is a power source that supplies power to the four fans 60. The power supply box 90 is provided with a switch for turning on / off the drive of the fan 60. When wearing the cooling garment, the power supply box 90 is attached to, for example, a pants belt. Further, the power supply box 90 may be stored in a dedicated pocket provided in the clothing section 10.

 As batteries, secondary batteries are usually used from the viewpoint of economy. However, most preferably, a fuel cell is used as the cell. Fuel cells are smaller than rechargeable batteries and do not require much time to charge. Moreover, fuel cells are considered to be compatible with cooling clothing. Due to its characteristics, a fuel cell is not suitable when a large amount of current needs to flow at one time, but is suitable when a constant current flows gradually. In the case of cooling clothing, batteries are used to drive the fan 60, so that there is no sudden rising current.

 By the way, since a fuel cell generates water vapor at the time of power generation, when a fuel cell is used as a power source in a cooling garment, the water vapor generated from the fuel cell may wet the cloth portion 10. For this reason, it is desirable that the fuel cell be provided in the fabric portion 10 at a location having excellent air permeability. Thereby, the water vapor can be discharged to the outside together with the circulating air, so that it is possible to prevent the cloth portion 10 from being wet by the water vapor.

Also, at a predetermined position (several places) on the back surface of the cloth part 10, as shown in FIG. 5, a cord fixing means 15 for fixing the connection cord 69 drawn out from each fan 60 is provided. ing. As the cord fixing means 15, for example, an elongated magic tape of lcm x 4 cm is used. This magic tape has the A and B sides integrated. Sew the tip of the magic tape on the back of the fabric part 10 Keep it. Then, the connection cord 69 is wound around with the magic tape, and the rear end of the magic tape is attached to the front end, whereby the connection cord 69 can be fixed.

 As shown in FIG. 2, the fan 60 includes a casing 61, a blade 71, a circuit (not shown), and a magic tape 72. The housing 61 includes a cylindrical member 65, a ring-shaped member 66, a disk-shaped member 67, and three holding members 68. The ring-shaped member 66 is provided at a predetermined position on the outer surface of the cylindrical member 65. The disk-shaped member 67 is provided inside the cylindrical member 65, and is held by three holding members 68 provided on the inner side surface of the cylindrical member 65. The casing 61 is integrally manufactured by injection molding using plastic. The height of the cylindrical member 65 (thickness of the fan 60) is about 6 mm.

 The blade portion 71 and the circuit portion are disposed inside the cylindrical member 65, and the circuit portion is mounted on the disk-shaped member 67. The circuit section includes a rotary motor (drive means), and a blade 71 is attached to a shaft of the rotary motor. The blade portion 71 has a diameter of, for example, 10 mm to 100 mm. At this time, the rotation axis of the blade portion 71 is substantially parallel to the central axis of the cylindrical member 65 and substantially perpendicular to the surface of the ring member 66. Such a fan 60 is required to have a certain exhaust capacity. For example, it is sufficient for the fan 60 to have a maximum air pressure difference of 50 Pa between the inside and outside of the clothing portion 10 near the fan 60 when driven. Therefore, it is sufficient to use a fan having a static pressure of 150 Pa at the maximum as the fan 60. In addition, the larger the air volume of the fan 60, the higher the cooling effect. However, the air volume of all the fans 60 is desirably at least 1 liter / sec.

 It is desirable to use a fan having a weight of 40 g or less as the fan 60. This is to prevent the fabric part 10 from being deformed by the weight of the fan 60. Also, it is desirable that the noise of the fan 60 be 40 dB [A] or less.

When the blade 71 is rotated, the air in the spacer 20 flows from one opening of the cylindrical member 65 toward the blade 71, and the air flows into the cylinder via the blade 71. It is discharged outside through the other opening of the shaped member 65. The fan 60 has a size It has a large air volume and is suitable for use in the cooling clothing of the first embodiment. However, in order to take in the air in the spacer section 20 into the cylindrical member 65, a certain space must be provided between the end face of the cylindrical member 65 facing the underwear and the underwear. No. Generally, the size of this space is determined according to the diameter of the fan 60.

 The magic tape 72 is bonded to the back surface of the ring-shaped member 66. The magic tape 72 is for detachably attaching the fan 60 to the clothing portion 10. Assuming that the magic tape 72 is on the side A, the magic tape 16 on the side B is sewn around the air outlet 50 on the back surface of the cloth part 10, as shown in FIG. . By attaching these two magic tapes 72 and 16, the fan 60 is attached around the air outlet 50. For this reason, when cooling clothing is worn, the rotation axis of the blade 71 becomes substantially perpendicular to the surface of the underwear. The reason why the shape of the ring-shaped member 66, which is the bonding portion of the magic tape 72, is circular is that when the magic tape 16 paired with the magic tape 72 is attached to the clothing material portion 10, This is because the mounting area is desirably as small as possible. On the other hand, when removing the fan 60 from the cooling garment, first, the magic tape as the cord fixing means 15 is peeled off to release the fixed state of the connection cord 69. Next, the magic tape 72 of each fan 60 is peeled off, and the four fans 60 are removed from the cooling clothes. Thus, anyone can easily remove the fan 60 easily. Instead of attaching and detaching the fan 60 with the magic tape 72, the fan 60 may be attached and detached using a sheet magnet. By making the fan 60 and the power supply box 90 detachable in this way, not only can the cooling clothes be easily washed, but also the advantage that only the fan 60 can be replaced when the fan 60 is broken. is there.

Further, the fan 60 is designed so that the fan 60 does not protrude from the mesh material 51 of the air outflow portion 50 when the fan 60 is mounted around the air outflow portion 50. That is, as shown in FIG. 2 (b), on the back side of the fan 60, the distance d between the end face of the cylindrical member 65 and the ring-shaped member 66 is determined by the thickness of the magic tape 72 and the air outlet. It is designed to be the sum of the thickness of the magic tape provided at 50. As a result, as shown in FIG. 4, the fan 60 is attached to the cloth material portion 10. At this time, the end face of the fan 60 is substantially flush with the surface of the clothing portion 10. Therefore, the wearer of the cooling garment does not obstruct the fan 60 at the time of work, and the cooling garment is less likely to be uncomfortable. Generally, it is desirable to mount the fan 60 so that the end face of the fan 60 does not protrude more than 5 mm outward from the surface of the cloth material portion 10.

 When the fan 60 is driven, the blade 71 normally rotates at a constant speed. As a result, the fan 60 sends out air at a constant air volume. The present invention is not limited to this, and the fan 60 may perform so-called fluctuation air blowing, for example, by adjusting the air volume or adjusting the air volume to send out air. In this case, if a variable resistor or the like is used to change the number of revolutions of the blade 71, power is lost, so a modulation method such as PWM (pulse width modulation) is used, or — It is desirable to change the voltage immediately after the DC converter. Further, a temperature sensor or a temperature / humidity sensor may be provided inside the cooling garment, and the rotation speed of the blade portion 71 may be controlled based on the temperature or the temperature / humidity detected by the sensor.

 During outdoor work, when the rain suddenly falls, the fan 60 gets wet, but as a countermeasure against this, it is desirable that the circuit part of the fan 60 be waterproofed. Specifically, as such a water-resistant treatment, it is conceivable to coat the circuit portion with a resin.

 The interval securing means 80 is for securing a constant interval between the fan 60 and the underwear. If the wearer of the cooling garment is working or performing any action, the underwear will wrinkle in any way. Due to the wrinkles, the distance between the upper end of the fan 60 (the end on the side facing the underwear of the fan 60) and the underwear is reduced, and it becomes difficult for air to flow into the fan 60. In such a case, the interval securing means 80 plays a role of suppressing wrinkles of the underwear and securing a flow of air.

As shown in FIG. 3 (a), the spacing means 80 has a main body 81 and four legs 82. The spacing means 80 has a thickness of about 0.3 mm, and is made of a soft and elastic plastic sheet or the like. The outer shape of the main body 81 is substantially circular, and the main body 81 has a plurality of openings. In the example of Fig. 3 (a), four fan-shaped openings are formed in the main body 8 1 and the main body 8 Reference numeral 81 denotes a case in which a ring-shaped portion and two intersecting linear portions located inside the ring-shaped portion are included. However, the size of the above-mentioned opening should be such that the creased underwear does not enter.

 As shown in FIG. 3 (b), the leg portion 82 has a notch portion 82 a that is long along the longitudinal direction at its tip end, and has two notches in the width direction. A short notch 82b is formed. The former notch 8 2 a is for narrowing the width of the leg 82, and the latter notch 82 b is for fixing the leg 82. is there. As shown in FIG. 2, the ring-shaped member 66 of the fan 60 is formed with four mounting portions 66 a for mounting the spacing means 80. The mounting portion 66a is formed so as to protrude from the surface of the ring-shaped member 66. Further, a hole for inserting the leg portion 82 is formed in each mounting portion 66a. To attach the spacing means 80 to the fan 60, first place the main body 81 in a position facing the fan 60, press the tip of one leg 82 with your hand, and reduce the width. Make it narrow. Then, in this state, the tip of the leg 82 is pushed into the predetermined mounting portion 66a. As a result, the two notches 82b of the leg 82 engage with the mounting portion 66a, and the leg 82 is fixed. Similarly, the other three legs 82 are fixed to the respective mounting portions 66a. In this way, as shown in FIG. 4, the spacing means 80 is attached so as to cover the surface of the fan 60 on the side facing the underwear. By providing the spacing means 80, when the underwear is wrinkled, the main body 81 of the spacing means 80 can block the wrinkled portion of the underwear. A constant interval can always be ensured between 0 and 0.

 Further, since the interval securing means 80 has elasticity, when it is pressed from the outside, it can easily move in the pressed direction. Therefore, when the spacing means 80 is in contact with the underwear, the wearer does not feel that the spacing means 80 is hard. Further, the interval securing means 80 is easily crushed when pressed, and can immediately return to the original state when released from the pressing force. Actually, it is sufficient to use a means having a very low elasticity as the means 80 for securing the interval.

For example, a wearer sits on a chair while wearing cooling clothes, and the back of the cooling clothes is When pushed by the back of the child, the spacing means 80 is crushed, and the main body 81 comes into contact with the upper end of the fan 60. As described above, the spacing means 80 is crushed by its elasticity, and does not give the wearer a rough feeling. However, when the main body 81 of the spacing means 80 is in contact with the upper end of the fan 60, air cannot flow into the fan 60, so that the cooling effect on the back is not very effective.

 Further, the spacing means 80 serves to prevent the wrinkled underwear from obstructing the air flow, and to provide a spacer for contacting the underwear and securing an air flow passage near the fan 60. As a role. In order for the gap securing means 80 to serve as a spacer, if the fan 60 is of a practical size, the main body 81 of the gap securing means 80 and the fan 6 on the side opposite thereto are required. The distance from the top of 0 must be at least about 2 mm. If the distance is smaller than 2 mm, the resistance of the circulating air will increase and the air volume will decrease.

 Note that, instead of the above-described fan 60, a side flow fan typified by a sirocco fan can be used for the cooling clothes of the first embodiment. A side-flow fan is a fan that radially sends out air taken in from the axial direction of the blade toward the outer periphery of the blade. When a side-flow fan is used for cooling clothing, the air inflow section is provided at the bottom of the cloth section, the air outflow section is provided at the top of the cloth section, and the side-flow fan is provided on the back of the cloth section 10 corresponding to the air inflow section. Attach in the position. FIG. 10 shows a schematic diagram of the side flow fan attached to the air inflow section. As shown in FIG. 10, the air drawn in by the side flow fan 600 from the air inflow portion 40 is radially sent out from the side surface of the side flow fan 600 into the air flow passage, and the air flow passage It is discharged to the outside from the air outlet through the inside. In particular, by using a side flow fan 600 having a thickness equal to or less than the thickness of the spacer 20, the wearer can wear the side flow fan 600 when wearing cooling clothing. There is no discomfort due to 0. When the side-flow fan is used for the cooling garment, it is not always necessary to provide the spacing means 80 due to the structure of the side-flow fan.

Next, the material of the cloth part 10 will be described. As a material of the cloth part 10, for example, a high-density cloth used for a down jacket surface material or the like is used. High-density fabrics are woven at a higher density than ordinary fabrics. As described later, the cooling of the first embodiment is performed. In the garment, the humid air warmed by the body flows through the air flow passage formed by the spacer portion 20 and is discharged from the air outflow portion 50 so that the air is removed from the outside air. Since the air is constantly replaced, it is necessary to prevent air from leaking from the cloth portion 10 while flowing through the air flow passage. Since the high-density cloth has a high yarn density, the amount of air leaking from between the yarns to the outside is very small, and most of the air passes through the air flow passage to reach the air outlet 50, from which it is discharged outside. Is done. For this reason, high-density fabrics are very desirable for use as a material for the fabric part 10. In addition, since high-density cloth is a cloth to the last, there is an advantage that when it becomes dirty, it can be easily washed with a home washing machine or the like. Such high-density fabrics are manufactured for various purposes and are available at low cost. It is preferable that the high-density cloth has poor air circulation. Specifically, when a high-density cloth is applied with a pressure of 5 Pa, the high-density cloth is used for a unit time and a unit. It is necessary to use air whose volume per unit area is 5 cc / cmVsec or less.

 In addition, as the material of the clothing portion 10, not only high-density cloth but also any material that does not substantially leak air can be used. In particular, if cooling clothing is used when performing work involving dirt, the material of the cloth part 10 should be made of a non-absorbent material such as vinyl or nylon with a smooth surface or water-repellent. It is desirable to use a certain material. This is to make it possible to easily remove dirt attached to the clothing material portion 10. In addition, if a material having a water-absorbing property is used as the material of the cloth material portion 10, when the cloth material portion 10 becomes wet due to rain or the like, the air flowing through the air flow passages absorbs moisture absorbed by the cloth material portion 10. It is used to evaporate water, and sweat from the body is not effectively evaporated. As a result, dirt does not permeate into the cloth portion 10 and dirt can be easily removed. In this case, the non-absorbent material has poor air permeability, and the moisture in the cooling garment cannot be radiated to the outside through the material, but the moisture passes through the air flow passage together with the air by the fan 60. There is no problem. When the cooling garment is worn mainly during outdoor work, it is desirable to apply a heat ray reflection treatment to the surface of the cloth portion 10.

Next, the structure of the spacer section 20 will be described in detail. FIG. 6 is a schematic plan view of a part of the spacer section 20, and FIG. 7 is a schematic enlarged perspective view of a part of the spacer section 20. The spacer section 20 shown in FIGS. 6 and 7 includes a spacer 21 and a cloth (sheet-like material) 31. Further, the spacer 21 includes a mesh member 25, a plurality of column members 26, and a plurality of connecting members 27. The mesh member 25 is formed in a substantially flat shape, and has a plurality of first rails 25a and a plurality of second rails 25b. The plurality of first rails 25a are arranged at regular intervals along the vertical direction in FIG. 6, and the second rails 25b are arranged at regular intervals along the horizontal direction in FIG. The arrangement interval of the first rails 25a and the arrangement interval of the second rails 25b are the same, so that the mesh of the mesh member 25 has a substantially square shape. Here, the arrangement interval of the first rails 25a and the arrangement interval of the second rails 25b are, for example, about 7 mm.

 Each columnar member 26 has a length component in the thickness direction of the mesh member 25, and is physically connected to the mesh member 25 at an intersection where the first rail 25 a and the second rail 25 b intersect. They are connected. In the first embodiment, in particular, each columnar member 26 is drawn vertically upward from the mesh member 25. For example, the length of the columnar member 26 is about 6 mm, and the thickness is about 1.5 mm.

 Each connecting member 27 connects the tips of two columnar members 26 located on one diagonal line among four columnar members 26 located around the predetermined mesh of the mesh member 25. Is what you do. For example, in a mesh located in an odd-numbered row from the left and an odd-numbered column from the top, the connecting member 27 connects the columnar member 26 located at the upper right and the columnar member 26 located at the lower left. It is formed as follows. In the mesh located in the even-numbered row from the left and the even-numbered column from the top, the connecting member 27 connects the columnar member 26 at the upper left with the columnar member 26 at the lower right. It is formed as follows. The connection members 27 are not formed in other meshes. It is desirable that the number of connecting members 27 be as small as possible. For example, if the connecting members 27 are provided in all the meshes of the mesh member 25, the spacer 21 lacks flexibility, and the comfort of the cooling garment becomes very poor. It is because.

Since each side of the first rail 25a and the second rail 25b and each connecting member 27 are also columnar members, the spacer 21 used in the first embodiment includes a plurality of columnar members. Using 26, it can be considered that they are three-dimensionally configured so that they are physically connected. Wear.

 Specifically, the spacer 21 can be easily manufactured by injection molding or the like using a material (thermoplastic resin) such as a soft plastic or a thermoplastic elastomer. That is, the heated and fluidized plastic is pressed into a mold to form the spacer 21. As can be seen from the structure of the spacer 21 described above, the spacer 21 can be integrally molded using a mold as shown in FIG. Is also not overlapped with other parts via space. Further, the spacer 21 has a feature that the ratio of the volume of the spacer 21 itself to the volume occupied by the outer shape is very small, light, and inexpensive. Therefore, it is desirable to use the spacer 21 at least a part of which is manufactured by injection molding.

 The spacer 21 is sewn to the fabric 31. Specifically, the spacer 21 is arranged at a predetermined position on the cloth 31 so that the mesh member 25 of the spacer 21 faces the cloth 31. Then, the thread 21 is sewn to the cloth 31 so that the thread is wound around the intersection of the mesh members 25. At this time, a plurality of small-sized spacers 21 may be collected and sewn to the cloth 31. This is because when manufacturing a large-sized spacer 21, a large amount of cost is required for manufacturing the mold, and the manufacturing cost of the spacer 21 is increased. In this way, by sewing the spacer 21 onto the cloth 31, three spacer portions 20 are obtained. Here, the size and size of each spacer section 20 are determined according to the mounting position and the like.

The cloth 31 is not necessarily a cloth, and any material such as a plastic film or a mesh material can be used as long as it is a sheet. Also, a plurality of small-sized spacers may be gathered together and their fabrics may be sewn together to form a large-sized spacer. The three spacer portions 20 are sewn to the positions of the clothing portions 10 corresponding to the left chest, the right chest, and the back, respectively. Specifically, first, the spacer portion 20 is arranged at a predetermined portion of the clothing portion 10 such that the cloth 31 of the spacer portion 20 faces the back surface of the clothing portion 10. Then, using a sewing machine or the like, the cloth 31 is sewn to the cloth part 10. At this time, it is desirable to sew only the end of the cloth 31 to the cloth part 10. This is because the sewing operation of the spacer portion 20 can be easily performed, and the seam can be made inconspicuous in the appearance of the cooling garment. As described above, in the first embodiment, the cloth 31 of the spacer section 20 is sewn to the cloth section 10, and thus the cloth 31 can be regarded as substantially a lining of the cloth section 10. Can also. ·

 As described above, when the air inflow portion is not provided, and, for example, air is introduced into the spacer portion from the opening end of the spacer portion at the neck portion, the spacer is brought close to the neck portion. It is necessary to extend the part and install it. At this time, a linear spacer may be individually attached to the neck, and air may be guided from the linear spacer to the extended spacer.

 When the cooling garment to which the spacer section 20 is sewn is thus worn, the connecting member 27 of the spacer 21 comes into contact with the underwear. The connecting member 27 plays a role in preventing the creased underwear portion from entering the interior of the spacer 21, similarly to the above-described interval securing means 80. In fact, when the connecting member 27 is not provided, when the wearer of the cooling garment is working, the undergarment is inevitably wrinkled, and the wrinkled part of the undergarment is a pillar 21 of a spacer 21. It gets between the members 26. For this reason, the wrinkled underwear portion impedes the flow of air in the airflow passage. In the first embodiment, by providing the spacer 21 with the connecting member 27, it is possible to reliably prevent the creased underwear from entering the inside of the spacer 21. it can.

 Note that a simple structure having no connecting member may be used as the spacer 21, and a mesh-shaped material may be attached to the side of the spacer 21 facing the underwear. That is, in this case, the mesh-shaped material plays a role of preventing the creased underwear portion from entering the inside of the spacer 21.

The spacer portion 20 has a purpose of securing a space between the clothing portion 10 of the cooling garment and the underwear, and allowing air to flow through the spacer portion 20. In order to improve the air flow, it is necessary to increase the aperture ratio of the spacer portion 20 in a plane perpendicular to the air flow direction. Specifically, it is desirable that the aperture ratio be 30% or more. On the other hand, in order for the air to sufficiently contact the surface of the underwear in contact with the spacer section 20, it is necessary to increase the aperture ratio of the spacer section 20 on the side facing the underwear. You. Specifically, the aperture ratio is desirably 20% or more. The spacer section 20 of the first embodiment is designed to satisfy these conditions, thereby improving the air circulation and, furthermore, the contact of the underwear in contact with the spacer section 20. Since the area can be reduced, the chance of direct contact between the underwear and the air can be increased. Further, such a spacer portion 20 has an advantage that it is extremely lightweight and has great flexibility.

 The space occupied by the outer shape of the spacer 21 is preferably 10 liters or less when the cooling garment is worn on the upper body. If the volume is larger than 10 liters, the efficiency of ventilating the air in the air flow passage is reduced. Further, the ratio of the volume of the spacer 21 ′ itself to the volume occupied by the outer shape of the spacer 21 is preferably 50% or less. Further, the total weight of the spacers 21 is desirably 400 g or less. In addition, it is desirable to apply antibacterial treatment to the spacer 21.

 By the way, the lower end of the cooling garment is open, and the air flowing between the clothing portion 10 and the undergarment may leak from the lower end of the clothing portion 10. In this case, the cooling garment has air leak prevention means. It is necessary to provide. For example, rubber may be inserted into the skirt portion of the cooling garment, and the hem portion may be contracted with the rubber so that the hem portion of the cooling garment closely adheres to the wearer's torso. In addition, the hem of the cooling garment may be closely attached to the wearer's torso with a string or a belt. In addition, a cooling garment can be manufactured in which a fan is provided near the center of the clothing area and an air inlet is provided not only at the top but also at the bottom of the clothing area. Even in this case, the above-described means for preventing air leakage is necessary. When manufacturing such cooling clothes, it is desirable that the spacer 21, the fan 60, and the power supply box 90 be made into parts and manufactured in advance. As a result, even when the cooling garment is applied to clothing other than work clothes, the cooling garment can be easily manufactured.

Next, the principle of cooling used in the cooling garment of the first embodiment will be described. FIG. 8 is a diagram for explaining the cooling principle used in the cooling garment of the first embodiment. In Fig. 8 (a), when a person A is in a room at a temperature of 30 ° C, the temperature distribution around the person A is schematically shown by an isothermal curve (dotted line). The body temperature of person A, a constant-temperature animal, is almost Assuming that this temperature is 36 ° C, assuming that there is no large convection in the room air, as shown in Fig. 8 (a), the temperature near person A is the highest, and As the distance increases, it gradually decreases and approaches 30 ° C.

 Fig. 8 (b) is a diagram schematically showing the temperature distribution when person A is in a room at room temperature 20 by an isothermal curve. As can be seen by comparing Fig. 8 (b) with Fig. 8 (a),

In the case of (b), the intervals between the isothermal curves are closer than in the case of Fig. 8 (a). In other words, the temperature gradient in Fig. 8 (b) is larger than that in Fig. 8 (a). The magnitude of the temperature gradient affects the amount of heat released and has a significant effect on how people perceive temperature. In other words, people feel more hot and cold as the temperature gradient is larger. Focusing on this point, in the first embodiment, the temperature gradient in the vicinity of the surface of the human body is forcibly increased to thereby make the person feel cool and comfortable. Fig. 8

(c) shows the temperature distribution when the person A wears the cooling garment of the first embodiment in a room with a room temperature of 30. The room temperature in Fig. 8 (c) is the same as that in Fig. 8 (a), but Person A wears a cooling garment, and the same temperature of 30 ° C in the air passage of the cooling garment. By keeping the air flowing, the 3 Ot isotherm is located slightly away from Person A's body. Therefore, the temperature gradient from the surface of Person A to the surroundings becomes very large, and is similar to the case of Figure 8 (b) when considering only the temperature gradient between Person A and the cooling garment. .

 By wearing the cooling garment of the first embodiment and circulating air through the spacer section 20 and setting the temperature of a portion relatively close to the surface of the body to a temperature lower than the body temperature, in the vicinity of the surface of the body, Large temperature gradients can be realized. Due to this large temperature gradient, heat emanating from the surface of the human body is easily radiated to the side of the cooler garment and is quickly absorbed by the air flowing through the spacer section 20. Therefore, in the cooling garment of the first embodiment, the wearer can feel cool just by circulating the air into the spacer section 20 by the fan 60.

As mentioned above, a large temperature gradient near the body surface produces a large cooling effect, but the same is true for humidity. That is, when it is hot, the humidity near the body surface is about 100%. At this time, by creating a layer of outside air humidity near the body surface, a large humidity gradient can be realized near the body surface. it can. Such a large humidity gradient promotes the evaporation of sweat and makes people feel cool.

 In the cooling garment of the first embodiment, a space is formed by a spacer portion 20 on the back surface of the clothing portion 10, and air is circulated through this space. In a situation where you are sweating but the sweat is not so absorbed by the underwear, the underwear allows water vapor to permeate, so the sweat passes through the underwear and the space between the fabric part 10 and the underwear Get into it. The water vapor is easily carried out to the outside by the air flowing in the spacer section 20, and the body is cooled directly by absorbing the heat of vaporization due to perspiration. That is, sweat from the body is brought into contact with air flowing through the spacer, thereby easing the sweat from the body, and cooling the body using the action of removing heat of vaporization from the surroundings during the vaporization. I do.

 Also, under the situation where sweat is drunk and most of the sweat is absorbed by the underwear, the sweat absorbed by the underwear is carried out by the air flowing through the space 20. So the amount of evaporation of the sweat becomes very large. This significantly lowers the surface temperature of the underwear. For example, if the room temperature is 30 and if air of the same temperature as the room temperature is sufficiently flown in the vicinity of the surface of the wet underwear, the surface temperature of the underwear lowers by about 3 ° (: ~ 5 ° C. If the underwear is in close contact with the body, there is water between the body and the underwear, and the thermal resistance of wet underwear is extremely small compared to the thermal resistance of dry underwear. There is a large temperature difference near the surface, and the wearer feels cold, so the inherent self-regulating function of human body temperature makes the wearer less sweaty and cool enough. I can feel.

 In this way, in a sweaty situation, the temperature gradient can be increased near the surface of the body and the humidity gradient can be increased, so that the wearer feels cooler and spends more comfortably. Can be.

 If the spacer (air flow passage) is separated from the underwear, the above cooling effect is reduced. For this reason, it is desirable to provide an adhesion means for bringing the spacer portion into close contact with the underwear.

Next, an environment in which a cooling effect can be obtained by the cooling garment of the first embodiment will be described. FIG. 9 is a graph for explaining an environment in which a cooling effect can be obtained by the cooling garment. In FIG. 9, the vertical axis represents humidity, and the horizontal axis represents temperature. On the left Curve S1 shows a curve where the wet bulb temperature is 30. The middle curve S 2 shows a curve at a wet bulb temperature of 33 ° C, and the right curve S 3 shows a curve at a wet bulb temperature of 36. It should be noted that such a graph was obtained in an environment having a sufficient airflow, and the results are schematically shown here.

 As can be seen from the cooling principle described above, the cooling effect cannot be obtained even if cooling clothes are used in an environment where sweat from the body cannot evaporate. Therefore, theoretically, in the environment corresponding to the area on the right side with the curve S 3 on the right side as the boundary in FIG. 9, it is considered that there is almost no cooling effect by the cooling clothes. Also, even under an environment corresponding to the area surrounded by the curve S3 on the right and the curve S2 in the middle, sweat from the body cannot evaporate much, so the cooling effect of the cooling clothes cannot be expected so much. On the other hand, in an environment corresponding to the area surrounded by the middle curve S2 and the left curve S1, sweat from the body can evaporate, and the cooling effect of the cooling clothes can be obtained. Then, under the environment corresponding to the left area with the left curve S1 as the boundary, sweat from the body can be sufficiently evaporated, and it is considered that the cooling effect by the cooling clothes is sufficiently obtained. The environment on the left side of the middle curve S 2 is the normal living environment of humans. For this reason, it is theoretically considered that the cooling effect can be obtained in any environment except for the unusual environment, in which the cooling garment is used.

 For example, even in a special environment where the humidity is close to 100%, the cooling effect of the cooling clothes can be obtained by devising the following measures. In other words, a powerful fan is installed at the position of the clothing section corresponding to the air inlet, and a container (cooling means) containing dry ice is attached in front of the fan. If the fan is rotated so that the outside air is introduced into the air flow passage, the heat and heat of the outside air around the fan decreases due to the heat of vaporization of the dry ice, so that the wearer can feel cool and comfortably. it can. Similarly, by cooling the outside air around the fan with a commercially available gel-like cooling body or small-sized cooling machine (cooling means), cooling clothing can be used even in a special environment.

In the cooling garment of the first embodiment, a spacer is provided between the clothing portion and the undergarment to secure an air flow passage, and a fan is used to forcibly generate air flow in the air flow passage. Allows air to flow approximately parallel to the body surface between the clothing area and the human body Therefore, the temperature gradient near the surface of the body can be increased. Therefore, the wearer can obtain coolness and comfort only by wearing such cooling clothes. In addition, in situations where sweating occurs, sweat can be carried out to the outside by the air flowing through the airflow passage, so that the body can be cooled directly by absorbing the heat of vaporization caused by sweating, and therefore the cooling effect Can be further increased.

 In particular, the provision of the air leak prevention means can reliably prevent the air flowing between the clothing portion and the underwear from leaking from the lower end of the clothing portion to the outside. Does not decrease.

 Further, in the cooling garment of the first embodiment, the space securing means is provided so as to cover the surface of the fan on the side facing the underwear, so that an air flow path can be secured between the fan and the underwear. At the same time, the upper end of the fan can be prevented from being blocked by the wrinkled underwear, so that the occurrence of a situation in which the cooling effect is reduced can be reliably prevented.

 In the first embodiment, the case where the cooling garment is worn on the underwear has been described. However, for example, the cooling garment may be worn directly on the bare skin.

 In the above-described first embodiment, a case has been described in which three spacer portions are attached to the portion of the clothing portion corresponding to the chest and the back to cool the chest and the back.For example, when the arms are also cooled. In addition, a spacer portion may be attached to a portion of the clothing portion corresponding to the arm portion, and a fan may be provided on the sleeve portion. Further, a small fan for blowing air to the local area may be separately provided at a position on the back surface of the clothing section corresponding to a local area where sweat is likely to be present, such as an armpit. In this case, it is not always necessary to introduce external air into the local area.

Further, in the first embodiment described above, the case where a member having a mesh member, a plurality of columnar members, and a plurality of connecting members is used as the spacer has been described. A spacer can be used. Generally, it is desirable that the interval between the columnar members is at most 7 O mm. The thickness of the spacer is desirably 2 mm or more and 30 mm or less. If the spacer thickness is less than 2 mm, the air pressure must be considerably increased to allow a constant flow of air, making it impractical. Because it is. In particular, since the air flow is large around the fan, it is desirable that the thickness of the spacer provided around the fan be 5 mm or more. On the other hand, if the thickness of the spacer is larger than 30 mm, the appearance and comfort are deteriorated, and moreover, the problem that air becomes laminar and flows through the air flow passage tends to occur. If the air has a laminar flow, the air flowing on the body side and the air flowing on the cloth side in the air flow passage are not mixed with each other, and a large cooling effect cannot be obtained. In order to solve the problem of laminar flow generation, for example, air stirring means for stirring the air flowing in the air flow passage is provided at various points in the air flow passage, whereby the air flow in the air flow passage is reduced. May be generated.

 In the above-described first embodiment, the case where the spacer portion is manufactured by sewing the spacer to the fabric has been described. For example, the mesh member of the spacer is ultrasonically fused and heated. It may be attached to a fabric by fusion to form a spacer portion. At this time, it is necessary to use a fabric having a higher melting point than the material of the spacer. By attaching the spacer to the fabric by ultrasonic fusion and heat fusion in this way, the work efficiency can be improved as compared with the case where sewing is performed with a thread.

 Further, in the first embodiment described above, the case where the spacer portion is attached to the clothing portion by facing the back surface of the clothing portion to the back surface of the clothing portion and sewing the fabric to the clothing portion is described. However, conversely, as shown in FIG. 11, the connecting member of the spacer section 20 is opposed to the back surface of the cloth section 10, and the cloth 31 of the spacer section 20 is changed to the cloth section 10. It may be sewn to. In this case, the area of the cloth 31 to which the spacer 21 is not attached is increased so that the cloth 31 can be easily sewn to the clothing section 10. Also, if the spacer 20 is attached to the clothing 10, the entire spacer 21 will be covered by the cloth 31, so the spacer 20 will be attached from the end of the spacer 20. It is desirable to use a mesh material for the cloth 31 so that air can easily flow through the inside. Further, in this case, since the cloth 31 exists between the spacer 21 and the underwear, the wrinkled underwear portion enters the interior of the spacer 21. It doesn't happen. Therefore, the spacer 21 having a simple structure without a connecting member can be used.

Further, in the first embodiment, the spacer is attached to the fabric as the spacer portion. In the above, the case of using a spacer is described. However, the fabric may not be used, and a single spacer may be used as the spacer. In this case, in order to attach the spacer to the clothing portion, for example, the spacer is directly heat-sealed to the back surface of the clothing portion 10.

 In the first embodiment described above, the case where the front part of the cooling garment is opened and closed with a fastener has been described. However, for example, the front part of the cooling garment may be opened and closed using a Velcro. The cooling garment can also be applied to a garment in which the rear portion is opened and closed with a fastener or the like, or a garment in which the front and rear portions are not open and worn by wearing over the head.

 In the first embodiment described above, the case where the fan is detachably attached to the clothing portion using the magic tape has been described. However, the fan may be attached to and detached from the clothing portion by the following method. FIG. 12 is a diagram for explaining another example of a method of mounting a fan. In this method, a fan holding section (holding means) 160 as shown in FIG. 12 (a) is sewn to the periphery of the air outflow section on the back surface of the clothing section. The shape of the fan holding portion 160 is substantially annular, and the diameter of the inner circle is substantially the same as the diameter of the cylindrical member 65 of the fan 60. Further, two retaining claws 161 are formed on the fan holding portion 160. On the other hand, the fan 60 is substantially the same as that shown in FIG. 2, but differs in the following two points. That is, the first difference is that no magic tape is provided on the fan 60, and the second difference is that the ring-shaped member 66 of the fan 60 has two cuts as shown in FIG. 12 (b). The point is that a notch 66b is formed. First, the fan 60 is brought into contact with the fan holding portion 160 by aligning the position of the notch portion 66 b of the fan 60 with the engaging claw 161 of the fan holding portion 160. Then, by rotating the fan 60 around the central axis of the blade portion 71, a part of the ring-shaped member 66 located around the notch portion 66b and the locking claw 161 are formed. Is engaged. Thus, as shown in FIG. 12 (c), the fan 60 is attached to the fan holding section 160. It should be noted that the fan holding portion 160 may be bonded to the clothing portion instead of being sewn to the clothing portion.

In the first embodiment described above, the case where four fans are provided in the cooling garment has been described, but the number of fans is not particularly limited, and one, two, three, or five or more fans are provided. You may. Similarly, for the air inlet and the air outlet, Yes, there is no limit. One, two or four or more air inlets may be provided, and one, two, three or five or more air outlets may be provided.

 Also, in the first embodiment described above, a case where power is supplied from one power supply box to four fans has been described.For example, by providing a power supply and a control circuit for each fan individually, It may be designed to be cordless inside the cooling garment. By using a cordless fan, for example, it is possible to easily attach and detach each fan while wearing cooling clothing, and to easily replace secondary batteries. In this case, a receiving circuit may be provided for each fan, and a signal may be wirelessly transmitted from an external transmitting means to the receiving circuit, so that the on / off and strength of the fan can be switched. Here, it is desirable to use a transmitting means having a size and a shape that can be put in a pocket, for example, a fountain pen. Further, the transmission function may be incorporated in a mobile phone or the like. It is desirable that the receiving circuit has at least 100 unique communication identification codes in order to prevent interference. When the power supply is commonly used for all fans, a control circuit, a reception circuit, and a communication identification code decoding circuit may be attached to the power supply. Further, for example, when the wearer of the cooling garment works in a fixed work place without moving, the electric power supplied to the fan may be obtained from a commercial power supply. Alternatively, cooling clothing may be used while charging the secondary battery with commercial power. The above control circuit controls on / off of the fan and controls the rotation speed of the blade. Although the drive control of the fans is performed by the control circuit for each fan, for example, the four fans may be divided into a plurality of groups, and the drive control of the fans may be performed for each group.

Further, in the above-described first embodiment, a cover may be attached to the air inflow portion and the air outflow portion as necessary. The cooling garment has a certain degree of cooling effect even when the fan is not driven, for example, because the air that has flowed in from the air inlet flows through the air flow passage and flows out from the air outlet. For this reason, when it is cold, the cooling effect of the cooling garment can be temporarily eliminated by closing the air inflow portion and the air outflow portion with the cover. As a means for attaching the cover, for example, a button can be used. In the first embodiment described above, it is desirable to use a polyurethane elastic material called, for example, spandex for a part of the underwear. As a result, the underwear and the body come into close contact with each other, so that a decrease in the cooling effect can be prevented. In this case, it is desirable to use a water-absorbing material for the underwear.

 Next, a second embodiment of the present invention will be described with reference to the drawings. Fig. 13 (a) is a schematic front view of a cooling garment according to the second embodiment of the present invention, and Fig. 13 (b) is a schematic rear view of the cooling garment. In the second embodiment, components having the same functions as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

 As shown in FIG. 13, the cooling garment of the second embodiment has a cloth portion 10 a, three spacer portions 20 a, and two air outflow portions (air flow ports) 50 a. It comprises two fans (blowing means) 60, two space securing means 80, a power supply box 90, and an air leak preventing means (not shown). In the second embodiment, a case will be described in which such a cooling garment is applied to a garment such as a shirt, the hem portion of which is worn in pants or a skirt. Therefore, it is necessary to lengthen the hem part of the cloth part 10a to some extent. In this case, placing the hem of the cloth material portion 10a in pants or the like corresponds to the means for preventing air leakage. Also, this cooling garment is a short-sleeved garment, of which the front is closed with a button. The cooling garment is worn over underwear.

The three supporting portions 20a are for forming an air flow passage for allowing air to flow between the clothing portion 10a and the underwear, and are provided on the back surface of the clothing portion 10a. Widely provided in the center. As shown in FIG. 6, the spacer portion 20a has a spacer 21 and a cloth 31, and the structure is substantially the same as that of the first embodiment. Further, the spacer portion 20a is, as in the first embodiment, arranged so that the cloth 31 is opposed to the back surface of the cloth portion 10a, and the cloth 31 is positioned at a predetermined position of the cloth portion 10a. It is attached to the fabric part 10a by sewing with a thread. The only difference between the spacer portion 20a of the second embodiment and that of the first embodiment is the size and shape of the spacer portion 20a. More specifically, each spacer portion 20a is sewn at the position of the clothing portion 10a corresponding to the left chest, the right chest and the back, but is particularly provided at the position corresponding to the back. Taichi The size of each spacer portion 20a, so that the left side portion and the two left side portions provided at the positions corresponding to the left and right breasts are respectively connected at the positions corresponding to the right and left side portions, The shape is designed. That is, the three spacer sections 20a constitute one large air flow passage as a whole.

 When cooling not only the chest and the back but also the abdomen and the waist, a spacer 20a may be provided at the bottom of the cloth 10a. At this time, the fabric portion 10a is put in trousers, etc., but due to the space portion 20a provided at the hem portion, air is also blown from below the fabric portion 10a. Go into part 20a.

 In the second embodiment, since the cooling garment is applied to the shirt, a button is used as a means for closing the front part. When a button is used, air may leak to the outside through the gap between the vertically adjacent buttons. In order to prevent such air leakage, for example, it is conceivable to increase the width of the fitting portion at the front of the shirt. Also, the number of buttons may be increased to reduce the distance between the buttons. Furthermore, ヮ Velcro, fasteners, etc. may be attached to the mating portion of the front part of the door, and buttons for decoration may be provided to make the appearance look like a shirt.

 The two air outflow portions 50a are formed at predetermined positions of the clothing portion 10a corresponding to the lower end of the spacer portion 20a provided at a position corresponding to the back. Specifically, the two air outflow portions 50a are formed at positions slightly deviated from the left and right side portions toward the back and below the clothing material portion 10a. For example, the air outflow portion 50a is formed by cutting out a predetermined portion of the cloth material portion 10a, and sewing the mesh material 51 from the back surface of the cloth material portion 10a to the cutout portion. Formed by

The two fans 60 are for forcibly generating an air flow in the support section 20a, and are provided on the back of the cloth section 10a corresponding to each air outlet section 50a. Mounted in position. In the second embodiment, since the two fans 60 are attached to the position of the clothing portion 10a slightly shifted to the back from the left and right side portions, the arm of the wearer of the cooling garment is attached to the fan 60. Fan 60 will not be in the way if you hit it carelessly. The power supply box 90 is a power supply for supplying power to the two fans 60. The structures of the fan 60 and the power supply box 90 are substantially the same as those of the first embodiment. The same is true.

 The space securing means 80 is for securing a constant space between the fan 60 and the underwear, and its structure and function are substantially the same as those of the first embodiment. .

 Next, the material of the fabric portion 10a will be described. In the second embodiment, different materials are used for the upper part of the cloth part 10a and the other parts. That is, a material having good air circulation is used for the upper part of the cloth part 10a, and the air other than the upper part of the cloth part 10a is substantially air-permeable, as in the first embodiment. Use a material that does not leak. For this reason, outside air can flow into the spacer part 20a from the upper part of the cloth part 10a. In the second embodiment, an air inflow portion is not formed by cutting out a part of the clothing portion as in the first embodiment, but instead, the upper portion of the clothing portion 10a serves as an air inflow portion. Will fulfill. The portion of the upper portion of the cloth portion 10a, which plays the role of the air inflow portion and in which a material having good air circulation is used, is also referred to as an "air permeable portion". In the second embodiment, for example, a portion of the clothing portion 10a from the shoulder to a position about 5 cm below the shoulder is defined as an air-permeable portion. Further, it is desirable to perform a water-repellent treatment on the air permeable portion. If such a treatment is not performed, if the air permeable portion becomes wet with water, the air circulation at that portion is significantly reduced.

 Here, in order to efficiently take in air from the air permeation part of the cloth part 10a into the spacer part 20a, the part of the cloth part 20a is partially made of the cloth part 10a. It is provided on the cloth portion 10a so as to overlap with the air permeable portion of the garment. Then, the air that has flowed into the spacer portion 20a flows through the air flow passage formed between the clothing portion 10a and the underwear by the spacer portion 20a. Become.

Further, as the material having good air circulation to be used for the air permeable portion, it is preferable not to use a material which can be seen at a glance between the air permeable portion and the other portion in the cloth portion 10a. This is to reduce the sense of discomfort in the appearance of the cooling garment. For example, a mesh-like material with a very coarse knit, which allows underwear to be seen through too much, is not suitable as a material for the air-permeable part, but a material with a certain degree of fine knitting should be used. it can. Therefore, the outside air is When flowing into the spacer portion 20a from the excess portion, the material used for the air permeable portion receives some resistance. For this reason, in order to take in a sufficient amount of air into the spacer portion 20a, it is desirable to increase the area of the air permeable portion. Next, a description will be given of the air circulation required for the cloth material portion 10a. Here, the spacer portion 20a is sewn on the back surface of the cloth portion 10a, so when considering the air circulation of the cloth portion 10a, the cloth portion 10a and the spacer portion are considered. It is necessary to consider the 20a fabric 31 as one.

Now, when a pressure of 5 Pa (approximately 0.5 mmH ₂と し て) is applied to the cloth part 10 a and the cloth 31 as a quantitative physical quantity representing the air circulation of the cloth part 10 a and the cloth 31, Consider the volume of air (cc / cmVsec) that passes through the cloth part 10a and the cloth 31 per unit area per unit time. In order to obtain a good cooling effect when wearing cooling clothing, it is necessary to ensure that a sufficient amount of air can be taken in the air permeable part of the clothing material part 10a that serves as an air inlet. No. On the other hand, it is necessary to prevent air from leaking too much in the portion other than the air-permeable portion of the cloth portion 10a, for example, in the vicinity of the fan 60. Results of experiments by the present inventors, even without low amount of air passing through the cloth part 10 a and fabrics 31 corresponds to the air permeation site is ² c cZcm 2 sec, cloth part corresponding to the portion other than the air permeability site It has been found that a sufficient cooling effect can be obtained by using the cloth portion 10a and the cloth 31 such that the amount of air passing through the cloth 10a and the cloth 31 is at most 1 cc / cm ² / sec.

However, for example, in the case of using the fan part 20a designed to sufficiently reduce the resistance of the flowing air and using the fan 60 having a large air volume, the cloth part 10a and the cloth The above-mentioned restrictions on air circulation in the above can be relaxed. That is, in this case, the amount of air passing through the cloth portion 10a corresponding to the air-permeable portion and the cloth 31 is at least 10 cc / cmVsec, and the cloth portion 10a corresponding to a portion other than the air-permeable portion. A good cooling effect can be obtained by using the cloth portion 10a and the cloth 31 such that the amount of air passing through the cloth 31 is at most 5 cc / cmVsec. In this way, the air passing through the cloth portion 10a and the cloth 31 is formed by the pressure of the fan 60 and the air receiving by the fan 21. Although the air volume varies, in general, the amount of air passing through the cloth part 10a and the cloth 31 corresponding to the air permeable part is the cloth part 10a and the cloth 31 corresponding to the part other than the air permeable part. It is desirable that the air volume is at least three times larger than the amount of air passing through.

 Since the cloth 31 of the spacer section 20a can be considered as a lining of the cloth section 10a, the air flowing through the air flow passage by the cloth 31 is not limited to the upper part of the cloth section 10a. May be prevented from leaking out of the portion. For example, a portion of the cloth 31 corresponding to the upper portion of the clothing portion 10a is provided with a material having good air circulation, and a portion corresponding to a portion other than the upper portion of the clothing portion 10a is substantially air-permeable. Use a material with low leakage. For the fabric portion 10a, a material having good air circulation is used for all portions. As a result, a sufficient amount of air can be taken into the spacer portion 20a from the upper portion (the air-permeable portion) of the cloth portion 10a, and air can be extracted from portions other than the upper portion of the cloth portion 10a. It is possible to prevent leakage to the outside. In this way, by controlling the amount of air flowing in or out through the cloth part 10a by the cloth part 31, the same cloth can be used for the entire cloth part 10a. The appearance of the ground portion 10a can be improved, and the cost of manufacturing the cooling garment can be reduced because controlling the air permeability with the cloth 31 is less expensive than controlling the air permeability with the cloth portion 10a. There is an advantage that it can be suppressed.

 Here, as a method for producing the cloth 31 having these two properties, for example, the following method can be used. That is, first, a material having good air circulation is prepared. Then, a portion corresponding to a portion other than the upper portion of the clothing portion 10a in the material is laminated with a material having substantially less air leakage, for example, a plastic film or the like. In particular, it is desirable to use a film having high moisture permeability in a portion of the cloth material portion 10a where air movement is small, such as a portion corresponding to the vicinity of a trouser belt or the like. As a result, air can be substantially prevented from leaking from the portion laminated with the plastic film or the like. By using such a method, the fabric 31 can be easily and inexpensively manufactured. This method can also be applied to the case where the air circulation is controlled in the cloth portion 10a.

By the way, materials with good air circulation are soft and have no tenacity. This Therefore, if a material with good air circulation is used in the upper part of the cloth part 10a, and the thickness of the spacer 21 is increased, the spacer 21 is formed in the upper part of the cloth part 10a. The shape may be reflected, or the cloth 21a may be wrinkled due to the pressing force of the spacer 21. By increasing the area of the upper part of the fabric part 10a that uses a material with good air circulation, a sufficient amount of air can be taken into the spacer part 20a. The thickness of the spacer 21 can be reduced in the upper portion of the portion 10a and at a portion away from the airflow passage at the center of the clothing portion 10a. This is because, as the distance from the airflow passage in the center of the cloth part 10a increases, the amount of air taken into the cloth part 10a can be reduced. It is. Therefore, in such a case, by using a spacer in which the thickness of the portion corresponding to the upper part of the cloth part 10a is reduced, the shape of the spacer 21 is formed on the upper part of the cloth part 10a. There is no reflection. Also, even if the spacer portion 20a is provided at the position of the back of the clothing material portion 10a corresponding to the shoulder, it does not give the feeling of the shoulder of the wearer of the cooling garment rising. . Furthermore, the comfort of the cooling garment can be improved. ,

 In addition, instead of reducing the thickness of the spacer 21 at the portion corresponding to the upper part of the fabric portion 10a, the resistance of the flowing air is large, but a three-dimensional woven fabric with a soft touch is used. This type of spacer can also be used. In general, as the spacer portion 20a, a material in which various spacers having different thicknesses, materials, and the like are attached to the cloth 31 can be used. In particular, by changing the thickness of the spacer for each part of the spacer part 20a, the air volume at each part can be adjusted. For example, when using the spacers shown in FIGS. 6 and 7 to change the thickness of the spacer, it is necessary to change the length of the columnar member for each part in a large-sized spacer. Alternatively, a plurality of small size spacers having different lengths of the columnar members may be attached to each part. As described above, various spacers having different thicknesses, materials, and touches may be used in combination in the spacer portion 20a for each portion. In addition, it is desirable to use a contacting means that makes the air flow passage adhere to the underwear so that the thickness of the air flow passage does not exceed the thickness of the spacer 21.

The cooling garment of the second embodiment has the same operation and effect as those of the first embodiment. Play. In particular, in the cooling garment of the second embodiment, air is taken into the airflow passage by using the material of the clothing material, and the two air outlets are slightly shifted from the left and right sides to the back. Since the cooling garment is located at the location of the clothing, the cooling garment cannot be seen when viewed from the front, and the fan is invisible, just like a normal shirt. The only difference in appearance from ordinary shirts is that two air outlets are provided at the position of the clothing part, which is slightly shifted toward the back from the left and right sides. For this reason, there is almost no discomfort in appearance even when cooling clothes are worn. Further, in the second embodiment, the two fans are provided at positions slightly shifted toward the back from the left and right side portions of the clothing portion, and are not provided in the center of the back. If the wearer sits on a chair, the air outlet of the fan will not be blocked. In this case, it is desirable to use a spacer having a strength that can withstand a force of at least 0.3 N per 1 cm ² as a spacer provided at a position where it comes into contact with the backrest of the chair. This ensures that when the wearer leans on the back of the chair, the spreader will not collapse.

 In the cooling garment of the second embodiment, when the two fans and the power supply box are removed, the difference from a normal shirt is that two air outlets are provided, and The only thing that is sewn on the back of the fabric part. Therefore, if the cooling clothes become dirty, they can be washed with the fan and power pox removed. However, irons cannot be applied to such cooling clothes because spacers are attached. For this reason, it is desirable to apply a permanent process to the clothing material in advance and memorize the shape.

 Also, the cooling garment main body from which the fan and the power supply box have been removed can be manufactured at low cost. For this reason, the wearer of the cooling garment purchases multiple sets of the cooling garment without the fan and the power supply box, and purchases at least one set of the fan and the power supply pox. It can be replaced and worn every day.

By the way, in the second embodiment, air is circulated through spacers provided at positions corresponding to the chest and the back by two fans provided at the position of the clothing part slightly shifted toward the back from the left and right sides. I have to do it. Two fans, slightly from the left and right side If it is placed at the position of the fabric shifted toward the back, air may flow in a skewed path inside the spacer, for example, avoiding the chest or the center of the back. In particular, since the back is a place where sweat is likely to be permeated, air guide means for guiding air along a predetermined path in the spacer section is provided in the air flow passage, and the air flows through the center of the back. It is desirable to pass. Specifically, a sponge is provided at a predetermined position in the spacer section to partition the space in the spacer section so that air flows through the center of the back in the air flow passage. Alternatively, a directional fan such as a sirocco fan may be used to blow the air flowing through the airflow passage toward the center of the back. Furthermore, the thickness of the spacer may be adjusted to reduce the resistance of the air at the center of the back so that the air can easily flow through the center of the back. In addition, the same method as described above may be used to allow the air to pass through the center of the chest.

 In the second embodiment, the case where the upper part of the cloth part is the air-permeable part and the two fans are provided at the position of the cloth part slightly shifted to the back from the left and right side parts has been described. For example, a portion of the clothing portion corresponding to one side portion may be an air-permeable portion, and one fan may be provided at a position of the clothing portion corresponding to the other side portion. Generally, as long as the air permeable portion and the fan (or air outlet) are provided on opposite sides via the air flow passage, the specific installation position may be anywhere.

 Also, if the cooling effect is to be considered first without giving much consideration to the appearance of the cooling garment, for example, a large fan with a diameter of at least about 5 Omm should be placed at the position of the clothing area corresponding to the center of the back. One large fan may be used to exhaust the air in the air flow passage to the outside, and a plurality of predetermined portions on the front side of the cloth portion may be used as the air permeable portions. As a result, a small amount of electric power of 1 or 2 watts can flow a large amount of air of about 10 liters Z sec into the air flow passage, and the large amount of air can wrap the entire surface of the fuselage. A very large cooling effect can be obtained. Naturally, conversely, a large fan may be provided at the position of the clothing portion corresponding to the center of the abdomen, and a plurality of predetermined portions on the back side of the clothing portion may be air-permeable portions.

In the second embodiment, the outside air is supplied from the air permeable portion into the air flow passage. In the above, the case where the air in the air passage is taken out from the air outlet is described.However, conversely, the air outlet is used as the air inlet, and the outside air is introduced from the air inlet into the air passage. The air in the air flow passage may be taken out from the air permeation part by taking in air.

 Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 14 is a diagram for explaining the cooling garment according to the third embodiment of the present invention. In the third embodiment, components having the same functions as those of the second embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The cooling garment of the third embodiment includes a cloth portion 10 a, three spacer portions 20 a, two fans 60, a power supply box 90, and a band-shaped cloth (partition means) 11. 0 is provided. The point that such a cooling garment differs from that of the second embodiment is that a material having good air circulation is used not only at the upper part but also at the lower part of the cloth part 10a, and a part of the cloth part 10a is cut out. At the point where the formed air outlet is not provided, and at the point where the fan 60 is mounted between the clothing portion 10a and the underwear so that the rotation axis thereof is substantially parallel to the surface of the underwear. is there. Other points are the same as those of the second embodiment. In the second embodiment described above, a case is described in which a material having good air circulation is used in the upper portion of the clothing portion, and a material that does not leak air is used in portions other than the upper portion of the clothing portion. In contrast, in the third embodiment, a material having good air circulation is used for the upper and lower portions of the cloth portion 10a, and a material that does not substantially leak air is used for the central portion other than the upper and lower portions. . The upper part of the fabric part 10a where a material with good air circulation is used is referred to as the "first air permeable part", and the lower part of the cloth part 10a with a material having good air circulation is used. The part that has been set is also referred to as a “second air-permeable part”. The first air permeable portion and the second air permeable portion correspond to the “air circulating portion” in claim 3. In the third embodiment, the first air permeable portion functions as an air inflow portion, and the second air permeable portion functions as an air outflow portion. Therefore, it is not necessary to cut out a part of the clothing part 10a to form an air inflow part and an air outflow part, and the cooling garment in this case is exactly the same as ordinary garment from the outside. There is no discomfort on the appearance. Also, the three spacer portions 20a are provided widely in the center of the back surface of the clothing portion 10a. In the third embodiment, the structure of the fan 60 is substantially the same as that of the second embodiment, but the method of mounting the fan 60 is different from that of the second embodiment. That is, as shown in FIG. 14, the belt-like cloth 110 is sewn along the waist direction on the back surface of the lower part of the clothing part 10 a and in the vicinity of the spacer part 20 a. . Here, rubber or the like is inserted into the end of the band-shaped cloth opposite to the side attached to the clothing material portion 10a to gather the cloth. In addition, two fans 60 are attached to predetermined positions of the belt-like cloth 110. As a result, the gears of the belt-shaped cloth 110 are in contact with the underwear, and the center axis of the blades of the fan 60 is substantially parallel to the surface of the body when the cooling garment is worn. In this way, the belt-like cloth 110 plays a role of dividing the space between the clothing portion 10a and the underwear into upper and lower portions, and corresponds to “partitioning means” in claim 3. Here, a small fan having a diameter of about 20 mm is used as the fan 60, for example. However, since it is desirable that the air volume of the fan 60 is large to some extent, it is preferable to use a fan 60 having a thickness of, for example, 10 mm or more. Instead of the fan 60, a vertically long blower such as a bellows may be used. By attaching the fan 60 in such a manner, the air that has passed through the air flow passage is exhausted downward by the fan 60, and then the lower part of the cloth part 10a having good air circulation ( (The second air passage). In addition, it is sufficient for the clothing portion located below the fan 60 to have a certain degree of air circulation. This is because the area of the cloth portion 10a located on the lower side is large, so that the air can flow out to the outside without much resistance.

 In the third embodiment, a case is described in which outside air is taken into the air flow passage from the upper portion of the clothing portion (first air permeable portion), and the taken air is circulated downward from above. As described above, by mounting the fan upside down on the above-mentioned band-shaped cloth, external air is taken into the air flow passage from the lower part of the cloth part (second air-permeable part), and the taken-in air May be distributed upward from below. The air in the air flow passage is heated by the body temperature, and ascending airflow and convection are generated in the air flow passage.From the viewpoint of utilizing the rising airflow, the air in the air flow passage is directed upward from below. Distribution is preferred.

The cooling garment of the third embodiment has the same operation and effect as those of the second embodiment described above. Play. In particular, in the cooling garment of the third embodiment, air is taken into the air flow passage and flows out using the material of the garment portion, and furthermore, the fan is located on the back side of the garment portion where the fan cannot be seen from the outside. Because it is provided, there is no discomfort in appearance even when wearing cooling clothing.

 In the third embodiment, the cooling garment may be applied to a garment of which the hem portion is worn without entering the pants or the like (for example, T-shirts, coveralls, etc.). In this case, since the lower end of the clothing portion is open, it is not always necessary to provide the second air permeable portion below the clothing portion. That is, generally, the air permeable portion may be provided on at least one of the upper portion and the lower portion of the clothing portion. Here, when the outside air is taken into the air flow passage from the air permeable portion, the air in the air flow passage is taken out from the end of the cloth portion, while the air flow passage is taken from the air permeable portion. When the air inside is taken out, the outside air is taken into the air passage from the end of the cloth.

 Next, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 15 (a) is a schematic front view of the middle garment of the cooling garment according to the fourth embodiment of the present invention, and FIG. 15 (b) is a schematic rear view of the middle garment. In the fourth embodiment, components having the same functions as those in the second embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

 The cooling garment of the fourth embodiment includes a garment main body and a middle garment. The clothing main body is substantially the same as the cooling garment of the second embodiment shown in FIG. 13 except that the spacer is not provided. That is, the garment main body is provided with a cloth portion 10a, two air outflow portions 50a, two fans 60, two space securing means 80, and a power supply box 90.

The middle garment is worn under the main body of the garment to secure an air flow passage for allowing air to flow between the main body of the garment and the surface of the underwear, and can be worn using a plurality of spacers. It is formed in a shape. In other words, middle clothing plays the role of a spacer. In the fourth embodiment, a case is considered in which middle clothing is applied to, for example, a best. As shown in FIG. 15, the inner garment includes three spacers 12 1 and a sheet material 13 1. The sheet-like material 1 3 1 has a shape that can be worn by people, such as a vest. Is formed. The spacer 122 is to secure a certain space along the surface of the underwear. On the surface of the sheet material 131, three spacers 1211 are sewn with thread. More specifically, each of the spacers 121 is sewn to the position of the sheet material 131 corresponding to, for example, the left chest, the right chest, and the back. Here, the spacers 12 1 do not overlap the portions of the sheet material 13 1 corresponding to the two fans 60. '

 As the sheet material 131, use a material that does not impair the air permeability, such as a mesh material. In particular, it is desirable to use a material that does not easily stain with sweat.

 It should be noted that the middle-clothes may be provided with improved comfort, antibacterial properties, or high functionality. In addition, it goes without saying that the thickness and type of the spacer may be changed according to each part.

 Such inner clothing is worn over underwear. Then, the clothing body is worn on the middle clothing. In this way, by wearing the inner clothing and the body of the clothing together, the inner clothing comes into contact with the clothing base 10a and the undergarment. An air flow passage can be secured between the part and the underwear.

 In the cooling garment of the fourth embodiment, the inner garment provided with a souser is configured separately from the garment main body, so that when the garment main body is washed, if the fan is removed from the garment main body, the garment main body is almost normal. Since it is the same as a shirt, the clothes can be washed easily and easily. Also, if the spacer is directly attached to the body of clothing, the spacer may wrinkle the body of clothing, but the spacer (medium clothing) and the body of clothing are separately configured. As a result, the body of the garment does not wrinkle and the appearance does not deteriorate.

In addition, if one piece of inner clothing is used, the inner clothing can be used in combination with various cooling clothing bodies (those without a spacer portion), so that economical costs by the wearer can be achieved. There is an advantage that the burden is reduced. Furthermore, since the clothing body is not provided with a spacer, the width of the mating portion at the front of the shirt (clothing body) can be made sufficiently large. For this reason, it is possible to prevent air from leaking from the gap between the buttons to the outside by making the width of the joining portion sufficiently large. Other effects are the same as those of the second embodiment. In addition, as the body of the garment worn over the inner garment, for example, when a polyurethane elastic material called spandex is used for at least a part of the garment, the distance between the undergarment and the cloth part is small. Because it is determined by the thickness, an object close to the designed air flow path can be obtained, and the cooling effect is enhanced. Also, when the above spandex is used for the sheet-like material of the inner garment, the inner garment adheres to the body, thereby improving the adhesion between the underwear and the body.

 It should be noted that a product in which a plurality of spacers are attached to underwear may be used as inner clothing. That is, for example, the spacer may be provided on the surface of the underwear and corresponding to the center of the clothing portion, and the clothing body may not be provided with the spacer portion. In this case as well, if the garment body is worn on the undergarment (medium garment) provided with the souser, an air flow passage can be secured between the central part of the clothing area and the undergarment.

 Further, as the inner clothes, a sheet-shaped material having a spacer attached to the back surface (the surface facing the underwear) may be used. At this time, a material having substantially less air leakage is used as the sheet-like material of the portion where the spacer is attached, and a material having good air circulation is used as the clothing portion of the garment body. Thus, the air flow passage can be formed only by wearing the inner clothes.

 Also, the cooling garment may be configured so that the middle garment can be easily attached to and detached from the back surface of the clothing portion using a button or the like. When the inner garment is attached to the back of the clothing section, the air circulation path can be secured between the center of the clothing section and the underwear only by wearing the garment body with the inner garment attached. Is less troublesome.

 Further, instead of attaching the fan to the clothing body, the fan may be attached to the inner clothing itself. In this case, a ventilation hole is provided in the portion of the clothing portion (air flow opening) corresponding to the fan, or a material having good air flow is used. In this case, when the garment body is worn on the inner garment, the position of the fan and the air circulation port is adjusted using, for example, a sheet-like magnet ring.

 Further, in the fourth embodiment, the case where the cooling garment is applied to the clothing of the second embodiment has been described, but for example, the cooling garment may be applied to the clothing of the first embodiment or the third embodiment. It is possible.

The present invention is not limited to the above embodiments, but falls within the scope of the gist. Various modifications and combinations are possible.

 In each of the above embodiments, the case where the chest and the back are cooled by wearing the cooling garment of the present invention has been described. However, the cooling garment may be worn, for example, only the back may be cooled. The back is very easy to sweat and its area is large, so even if you only cool your back, you can give the wearer a feeling of sufficient cooling.

 The spacer used in the cooling garment of each of the above embodiments has a feature that its thickness can be freely determined, and that it is very lightweight and excellent in flexibility. By taking advantage of the features of such spacers, it is also possible to produce a cooling garment in which only a spacer portion (or spacer) is provided on the back surface of the clothing portion. That is, the cooling garment includes only the clothing portion and the spacer portion, and does not include the air inflow portion, the air outflow portion, the fan, and the power supply box provided in the cooling garment of each of the above embodiments. At this time, a material with good air circulation is used for the clothing. Here, for the cloth part (including the cloth of the spacer part), when the pressure of 5 Pa is applied, the amount of air passing per unit time and per unit area is at least 3 cc / cmV. It is desirable to use something that is sec. Also in this cooling garment, similarly to the above-described embodiments, the air flow passage is formed between the clothing portion and the underwear by the spacer portion. In addition, in such a cooling garment, the spacer portion and the clothing material portion may be configured separately. For example, after wearing the inner garment in the above fourth embodiment, a garment made of a material having good air circulation may be worn on the inner garment.

FIG. 16 is a schematic cross-sectional view for explaining the flow of air in the cooling garment provided with only the spacer portion. When the wind is blowing, as shown in Fig. 16, the air enters the air flow passage through the cloth portion, passes through the air flow passage, and is discharged from the cloth portion to the outside. Also, even in the absence of wind, the air also enters the airflow passage through the clothing portion due to ascending airflow and convection due to body heat, and after passing through the airflow passage, from the clothing portion It is discharged outside. Naturally, this cooling garment is inferior to the cooling garments of the above-described embodiments, but, for example, when used for an application such as a fisherman or a cameraman in the summer season, there is a sufficient cooling effect. Has a cooling effect. Considering the effect of the updraft, if the cooling garment is composed of a separate clothing section (middle garment) and a separate clothing section (upper garment), the upper garment will not necessarily have air circulation. It is not necessary to use those made of good materials, and ordinary clothes may be used. Therefore, such inner clothes can be worn in combination with various types of outerwear.

 In addition, a jacket such as a business suit can be worn on the cooling garment of the present invention.
