Description

The present invention relates to an air-conditioning garment body that cools the body, and to the air-conditioning garment itself.

In recent years, air-conditioning garments that cool the body have been put into practical use and are rapidly becoming more widespread. As shown in Figure 10, a conventional air-conditioning garment 201 comprises a garment body 210 sewn from a material with low breathability, two fans 240, 240 attached to the lower rear of the garment body 210, a power supply unit (not shown) for supplying power to the two fans 240, 240, and a power cable (not shown) for electrically connecting the power supply unit to the two fans 240, 240.

When the fan 240 is operated, a large amount of air is drawn into the clothing body 210 from the fan 240. The pressure of the drawn-in air creates a positive pressure inside the clothing body 210, and as the clothing fabric expands, an air flow passage is automatically formed between the clothing fabric and the body or underwear. The drawn-in air flows upward through the formed air flow passage along the surface of the body or underwear and is discharged to the outside, for example, from around the collar or the cuffs. Here, the collar and the cuffs serve as air discharge sections 230.
As the air flows through the air flow passage between the clothing body 210 and the body or underwear, it evaporates sweat from the body, and the body is cooled by the heat of vaporization that occurs during evaporation (see, for example, Patent Document 1).

International Publication No. 2005/063065

However, with conventional air-conditioned clothing, if the fabric bulges too much, much of the taken-in air circulates away from the body, resulting in wasted air that does not contribute to cooling the body. Furthermore, with air-conditioned clothing for work, bulging, particularly near the fan, can cause the fan to protrude, potentially making it difficult to work in tight spaces and causing other problems. Furthermore, with air-conditioned clothing for general use, the bulging fabric can also cause problems with the appearance.

An object of the present invention is to provide an air-conditioning garment body and an air-conditioning garment that can have a fan attached to the front body .

In order to solve the above problems, the air-conditioning garment body according to the present invention comprises:
a fan opening into which the fan is fitted;
an air discharge unit that discharges the air taken in via the fan;
An opening and closing means for opening and closing the front body to the left and right;
Equipped with
The fan opening is formed in the center of the front body of the clothing body in the left-right direction ,
The opening/closing means is characterized in that it is provided at a position away from the center in the left-right direction .

According to the present invention , the fan can be attached to the front body part .

(Embodiment)
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes embodiments of the present invention with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

(First embodiment)
An air-conditioning garment 10 according to a first embodiment will be described with reference to FIG.
FIG. 1(a) is a schematic front view of an air-conditioning garment 10 using the garment body 1 of this embodiment, (b) is a schematic back view thereof, and (c) is a schematic cross-sectional view seen from the direction of arrow X in (a).
As shown in FIGS. 1(a) and 1(b), the air-conditioning garment 10 of this embodiment includes a garment body 1, fans 4, 4, a power supply unit (not shown), and a power cable (not shown).

The clothing body 1 is made of a sheet-like material with little or no breathability (air permeability) and is shaped to cover the upper body and arms. For example, in this embodiment, the clothing body 1 is made in the shape of a blouson-type top (workwear) with open cuffs.
The clothing body 1 is provided with two fan openings (opening holes) 12, 12, air exhaust sections 13 formed on the cuffs, collar and hem, opening and closing means 14 on the front body, and three spacing control sheets (spacing control planar bodies) 2a, 2b and 2c provided on the back side of the clothing body 1 (the side in contact with the body).

The two fan openings 12 are formed in predetermined areas of the clothing body 1, specifically in areas corresponding to the left and right hips. The fans 4 are fitted into the fan openings 12. In other words, the areas of the clothing body 1 around the fan openings 12 serve as fan mounting areas.

The front body opening/closing means 14 is used to open and close the front of the clothing body 1 when wearing the clothing body 1. Here, a zipper is used as the front body opening/closing means 14.

The three spacing restriction sheets 2a, 2b, and 2c each regulate the distance between the torso BD and the fabric 11; that is, they prevent the fabric 11 from expanding too much when a large amount of air is drawn into the garment body 1 from the fan 4, creating a positive pressure inside the garment body 1. Each of the three spacing restriction sheets 2a, 2b, and 2c is formed from a sheet-like material, with one end of the sheet provided with an elastic cord 22 as a means for fitting to the torso, and the other end sewn to the back of the fabric 11. Specifically, as shown in Figures 1(a) and 1(b), the spacing restriction sheet (hereinafter referred to as the "first sheet") 2a is provided at the seam 15a around the waist of the garment body 1. Furthermore, the spacing restriction sheet (hereinafter referred to as the "second sheet") 2b is provided at the seam 15b around the abdomen of the garment body 1. Additionally, a spacing restriction sheet (hereinafter referred to as the third sheet) 2c is provided at the position of the seam 15c around the armpits of the clothing body 1.

Next, the first sheet 2a will be described in detail with reference to FIG.
As mentioned above, Figure 1(c) is a schematic cross-sectional view seen from the direction of arrow X in Figure 1(a), i.e., it shows the cross-section of the part where the first sheet 2a is arranged. Generally, the vertical position (height position) of the elastic cord 22 that fits tightly against the torso BD will be located slightly below the position of the seam 15a due to the influence of gravity, but for the sake of simplicity, the following description will be given assuming that the vertical positions of the seam 15a and the elastic cord 22 are at the same position (same height position), i.e., that the first sheet 2a is kept horizontal.

As shown in Figure 1(c), the first sheet 2a is formed into a ring shape from a sheet-like material with little or no breathability (air permeability). An elastic cord 22 is arranged on the inner periphery of the first sheet 2a as a means for fitting to the torso, and both ends of this elastic cord 22 are sewn to the front body of the main garment 1 via spacing means 24. The outer periphery of the first sheet 2a is sewn to the back side of the fabric 11. The spacing means is intended to ensure air circulation space near the front body of the main garment 1.

The first sheet 2a has a flat portion with a radial width of 3 cm around the entire periphery, and a plurality of air vent holes 231 are formed in the flat portion. As shown in FIG. 1(c), the air vent holes 231 are designed so that the area occupied by the air vent holes 231 on the back side (near the fan 4) is smallest, and the area occupied by the air vent holes 231 increases from the back side to the front side, i.e., as the distance from the fan 4 (fan opening 12) increases. This design is because the positive pressure when air is taken in from the fan 4 is high near the fan 4 and the positive pressure decreases as the distance from the fan 4 increases. In other words, by making it difficult for air to flow out from the air vent holes 231 provided near the fan 4 and gradually making it easier for air to flow out from each air vent hole 231 as it moves away from the fan 4, the amount of air discharged through the first sheet 2a toward the hem of the air-conditioned garment 10 can be made uniform around the waist, thereby ensuring a uniform cooling effect. In the case of the air-conditioned garment 10 of this embodiment, since the hem is open, the positive pressure in the area below the first sheet 2a is low and the air-conditioned garment 10 does not inflate in that area.
Here, the first sheet 2a functions as a distance control means for controlling the distance between the torso BD and the fabric 11, and also functions as an air distribution means for adjusting the air flow rate around the waist where the first sheet 2a is provided.

Next, the second sheet 2b will be described.
Although not shown, the second sheet 2b is formed into a ring shape from a highly breathable (air-permeable) mesh sheet, and the radial width of its flat surface is 3 cm around the entire circumference. Similarly to the first sheet 2a, the second sheet 2b is provided on its inner periphery with an elastic cord 22 as a means for fitting to the torso, and both ends of this elastic cord 22 are sewn to the front body of the garment body 1 via spacing means 24. The outer periphery of the second sheet 2b is sewn to the back side of the fabric 11.
Here, the second sheet 2b functions as a distance control means for controlling the distance between the torso BD and the fabric 11, but unlike the first sheet 2a, does not function as an air distribution means. Note that the second sheet 2b may also function as an air distribution means by attaching a sheet-like material with little or no breathability (air permeability) to a predetermined position on the second sheet 2b.

Next, the third sheet 2c will be described.
Although not shown, the third sheet 2c, like the first sheet 2a, is formed into a ring shape from a sheet-like material with little or no breathability (air permeability). An elastic cord 22 is disposed on the inner periphery of the third sheet 2c as a means for fitting the third sheet 2c to the body, and both ends of the elastic cord 22 are sewn to the front body of the garment body 1 via spacing means 24. The outer periphery of the third sheet 2a is sewn to the back side of the fabric 11.

Similarly to the first sheet 2a, the third sheet 2c has a radial width of 3 cm around its entire periphery at its flat surface, and the flat surface is provided with a plurality of air vent holes 231. The area and arrangement of the air vent holes 231 in the third sheet 2c are designed in consideration of the air resistance around the collar and cuffs, which are the air exhaust section 13, so that the amount of air exhausted above the third sheet 2c is uniform around the entire periphery of the third sheet 2c.
Here, the third sheet 2c functions as a distance control means for controlling the distance between the torso BD and the fabric 11, and also functions as an air distribution means for making the air flow rate around the armpits where the third sheet 2c is provided uniform and for adjusting the air flow rate.

Furthermore, because the difference in air pressure between the top and bottom of the spacing restriction planar bodies (first sheet 2a, second sheet 2b, third sheet 2c) is extremely small, those that only function as spacing restriction means, such as second sheet 2b, need to have as little air resistance as possible. For example, if mesh is used, a highly air-permeable sheet material with an opening ratio of 70% or more is required. On the other hand, sheet materials that also function as air distribution means, such as first sheet 2a and third sheet 2c, have the purpose of guiding air to the air circulation holes (openings) 231, etc., so a sheet material with low air permeability is required. For example, a material with an opening ratio of around 20%, such as that used in breathable clothing, can be used.

Next, we will explain the air-conditioning garment 10 when the fan 4 is activated. Note that the method of installing the fan 4 and the power supply device and power cable for supplying power to the fan 4 are disclosed in Japanese Patent Application Laid-Open No. 2015-065998, and therefore will not be described here.
When the fan 4 is operated to introduce a large amount of outside air into the garment, positive pressure is created inside the garment, and in this embodiment, the positive pressure in the space between the first sheet 2a and the third sheet 2c increases. As mentioned above, the areas where the first to third sheets 2a to 2c are provided do not expand beyond the width (radial width) of each sheet.
A portion of the air flowing downward from the two fans 4, 4 is distributed by the first sheet 2a, and this portion of the air flows approximately uniformly around the entire circumference of the waist of the torso BD and is discharged from the hem. Therefore, the entire hem of the air-conditioned garment 10 functions as the air discharge section 13 provided at the bottom of the air-conditioned garment 10.
In addition, some of the air that flows downward from the two fans 4, 4 and the air that flows in other directions travels upward through the second sheet 2b, enveloping the torso BD, and is distributed by the third sheet 2c, so that the air is discharged from the air outlet 13 located above the third sheet 2c, specifically from the front collar opening, back collar opening, and cuffs.

As described above, with the air-conditioning garment 10 of this embodiment, the first sheet 2a, second sheet 2b, and third sheet 2c can control the amount of air flowing in each area inside the garment, preventing a decrease in cooling effect due to excessive inflation and improving the appearance. With the air-conditioning garment 10 of this embodiment, the air flow can be controlled according to the application and shape, further enhancing the cooling effect.

In this embodiment, the width (radial width) of each of the first to third sheets 2a to 2c is 3 cm around the entire circumference, but this is not limited to this. For example, rather than a fixed width, each sheet may have an optimal width depending on the purpose at each location. Also, in this embodiment, three sheets (spacing restriction sheets) are used, but this is not limited to this. One sheet or three or more sheets may be used.

Also, as shown in FIG. 2(a), each sheet (first to third sheets 2a to 2c) may be arranged approximately horizontally by suspending an elastic cord 22 with a string or the like from above the position of the fabric 11 where the sheets are sewn.
As shown in FIG. 2(b), the elastic cords 22 of the first sheet 2a, the second sheet 2b, and the third sheet 2c may be suspended with strings or the like from above the position of the fabric 11 where the third sheet 2c is sewn, so that these sheets are arranged approximately horizontally.
Furthermore, as shown in FIG. 2(c), each sheet (first to third sheets 2a to 2c) may have a folded piece bent downward from the main body (portion kept substantially horizontal), and the folded piece may be attached to the fabric 11 as an attachment allowance (seam allowance), thereby arranging these sheets substantially horizontally.

Second Embodiment
Next, an air-conditioning garment 110 according to a second embodiment will be described with reference to Figures 3 to 5. Note that components similar to those in the first embodiment are given the same reference numerals, and descriptions thereof will be omitted.

Figure 3(a) is a schematic front view showing the fan 4 used in this embodiment hanging from the neck, Figure 3(b) is a schematic front view showing the clothing body 101 of this embodiment being worn with the fan 4 inserted into the fan opening 12, and Figure 3(c) is a schematic back view of the same. Figure 4 is a schematic side view of the fan 4 used in this embodiment.

As shown in Figure 3(a), the fan 4 is not simply attached to the clothing body 101, but is attached to the clothing body 101 in a state of being suspended from the neck. As a result, even if the fan 4 becomes detached from the clothing body 101, the fan 4 is still suspended from the user's neck, so that the fan 4 can be prevented from falling.
As shown in Fig. 4, the fan 4 has a groove 411 formed on the side of the air intake part 41. When the fan 4 is attached to the clothing body 101, the groove 411 of the fan 4 is fitted into a fan opening 12 of the clothing body 101, which will be described later.

As shown in FIG. 3(b), the garment body 101 of this embodiment has a fan opening 12 formed in the garment fabric 11 corresponding to the abdomen for attaching the fan 4, and an elastic band (not shown) is arranged around the edge of the fan opening 12. This elastic band is used to tightly fit the fan opening 12 to the fan 4. As described above, the garment body 101 of this embodiment has the fan 4 attached to the abdomen, so the zipper 14 is located slightly to the left of the center. The garment body 101 of this embodiment also has an upper sheet 102a above the fan opening 12 and a lower sheet 102b below the fan opening 12. The dashed line 16a above the fan opening 12 of the garment body 101 shown in FIGS. 3(b) and 3(c) represents the seam of the upper sheet 102a, and the dashed line 16b below the fan opening 12 represents the seam of the lower sheet 102b. Furthermore, as shown in Figure 3(c), the garment body 101 of this embodiment has a vertically elongated mesh-shaped air outlet section 13 formed in the fabric 11 corresponding to the back. Note that the hem of the air-conditioning garment 110 of this embodiment is open, as in the first embodiment, and functions as the air outlet section 13.

Next, we will explain the procedure for using the air-conditioning garment 110 of this embodiment. Note that we will not explain the power supply unit and power cable used to supply power to the fan 4.

First, hang the fan 4 from your neck as shown in Figure 3(a). Next, put on the clothing body 101 and close the zipper 14 as shown in Figure 3(b). Then, attach the fan 4 to the clothing body 101 by fitting the edge of the fan opening 12 into the groove 411 on the side of the fan 4.

Next, we will explain the upper sheet 102a and lower sheet 102b, which are the spacing-regulating planar bodies of this embodiment. Like the first sheet 2a and third sheet 2c of the first embodiment, the upper sheet 102a and lower sheet 102b each function as air distribution means, and have appropriate air circulation holes formed in them, taking into consideration the shape of the clothing body 101, the position of the air outlet 13, and its air resistance, etc. Below, we will explain the upper sheet 102a and lower sheet 102b, focusing on the differences from the first sheet 2a and third sheet 2c of the first embodiment.

5(a) is a schematic diagram of the lower sheet 102b alone before being attached to the fabric 11, and FIG. 5(b) is a schematic diagram of the upper sheet 102a alone. The dashed line 211 in the figure indicates the seam line (seam line) when sewing to the fabric 11.
5(a) and 5(b), in this embodiment, a plurality of notches 241 are provided in each sheet (upper sheet 102a and lower sheet 102b), and the plurality of notches 241 serve the same function as the air vents 231 in the first embodiment when the sheets are sewn to the fabric 11. Therefore, the plurality of notches 241 provided in each sheet (upper sheet 102a and lower sheet 102b) can be considered as air vents.

Specifically, as shown in Figure 5(a), the lower sheet 102b has multiple cutouts 241, ... on the inside of the sheet, i.e., the side that comes into contact with the body, and the elastic cords 22 are exposed in the areas where the cutouts 241 are provided.
5(b), the upper sheet 102a has a plurality of notches 241 on the outer side of the sheet, i.e., on the side that will be sewn to the fabric 11. In other words, in the case of the upper sheet 102a, only the portions on the outer side of the sheet that do not have the notches 241 will be sewn to the fabric 11.

In addition, in the areas where the multiple cutouts 241,... are provided in each sheet (upper sheet 102a and lower sheet 102b), there will be no substantial bulging problems unless the width of the multiple cutouts 241,... is made extremely large. Also, although each sheet is formed in a ring shape, it does not necessarily have to be formed in a ring shape; for example, each sheet may be formed in a rectangular shape. In such a case, when each sheet is attached to the fabric 11 and the garment body 101 is worn, some wrinkling will occur, but this will not cause any major problems with the function of each sheet as a spacing control means.

Next, the air-conditioning garment 110 when the fan 4 is operated will be described.
When the fan 4 attached to the abdominal area of the garment body 101 is operated to introduce outside air into the garment, positive pressure is created inside the garment, and in this embodiment, the positive pressure in the space between the lower sheet 102b and the upper sheet 102a increases. Meanwhile, the distance between the body and the garment fabric 11 is maintained appropriately at each location where the upper sheet 102a and the lower sheet 102b are attached. The upper sheet 102a and the lower sheet 102b also function as air distribution means, so that air flowing left and right from the fan 4, enveloping the body, moves laterally around the torso and is discharged from the air outlet 13 at the back, air flowing downward passes through the multiple notches 241 in the lower sheet 102b and is discharged from the air outlet 13 comprising the entire hem, and air flowing upward passes through the multiple notches 241 in the upper sheet 102a and is discharged from the air outlets 13 at the front collar, back collar, and both arms.
In this embodiment, the fan 4 is placed on the abdomen of the clothing body 101, but it is of course possible to place the fan 4 on the back as if wearing it on one's back.

The function of the air distribution means in each seat (upper seat 102a and lower seat 102b) is not essential, but it is sufficient if each seat has at least the function of a distance regulation means. The same applies to the first seat 2a and the third seat 2c in the first embodiment described above.
In each embodiment, the gap regulating means is a sheet-like material, one end of which is provided with an elastic cord as a body-fitting means, and the other end is sewn to the back of the fabric. In other words, the gap regulating means is a gap regulating sheet provided with an elastic cord.

Next, we will explain the design and manufacturing procedure for an ideal air-conditioning garment using the present invention. Note that it is assumed that all sheets used as space-regulating sheets have small air permeability and are perforated.
1. Decide the design of the clothing body according to the purpose of use of the air-conditioned clothing, as well as the air volume, number of fans, and installation location.
2. Determine the volume and distribution of air flowing along each part of the body.
3. Based on the above points 1 and 2, determine the distance between the clothing material and the body at each part of the body.
4. Based on the decisions made in 1 to 3 above, determine the number of sheets (spacing control sheets) to be used and their installation locations.
5. Based on the above decision points, design the width and openings of each sheet for each part of the body.
6. Based on the decisions made in 5 above, cut out each sheet, taking into consideration the seam allowance (attachment allowance) and the space for attaching the elastic.
7. Make a pipe-shaped rubber cord guide.
8. The folded pieces of each sheet that can be folded downward from the main body are sewn to the inside of the garment body as seam allowances (attachment allowances).
9. Pass the elastic through the elastic threading made in step 7 above, and sew both ends of the elastic to the front body of the garment via the spacing means.
By following the above-described procedure for designing and manufacturing air-conditioning clothing, it is possible to create the best air-conditioning clothing for the intended use.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the sheet serving as the distance-regulating planar body is not limited to the sheets exemplified in the first and second embodiments as long as it can at least regulate the distance between the fabric and the body. For example, as shown in Fig. 6(a), the sheet serving as the distance-regulating planar body may be a plurality of rectangular pieces of fabric 21 arranged at predetermined intervals, with one end of each piece of fabric 21 sewn to the back surface of the fabric 11 and an elastic cord 22 attached to the other end. Furthermore, as shown in Fig. 6(b), the sheet serving as the distance-regulating planar body may be a plurality of triangular pieces of fabric 21 arranged at predetermined intervals, with one side (base) of each piece of fabric 21 sewn to the back surface of the fabric 11 and an elastic cord 22 attached to the vertex of each piece of fabric. Furthermore, as shown in Figure 6(c), the sheet as the spacing-regulating planar body may be, for example, the fabric 21 illustrated in Figure 6(a) rolled into a cylindrical shape and arranged at a predetermined interval, with one end of each fabric sewn to the back of the fabric 11 and an elastic cord 22 attached to the other end.

In addition, while the air-conditioned clothing has been described in each embodiment as a top, it may of course also be workwear or the like, in which the top and bottom are connected. Also, in each embodiment, the air-conditioned clothing is in the form of a blouson with an open hem, but this is not limiting, and it may also be, for example, a blouson with a tapered hem, or a shirt-type garment with the hem tucked into trousers.

Furthermore, in each embodiment, the spacing restriction sheets are arranged approximately horizontally around the fuselage, but this is not limiting, and the spacing restriction sheets may also be arranged diagonally around the fuselage.

In addition, in each embodiment, the sheet-like material with little or no breathability (air permeability) may be any material that has the relevant function, and may be, for example, a plastic sheet.

In addition, although each embodiment has been described using elastic cords as the torso-fitting means, rubber bands or other common methods may be used instead of elastic cords, and for example, a mesh-like tubular body (like a belly band) made of elastic fibers may be used. When this tubular body is used, the underwear is fitted tightly to the torso, preventing the creation of an insulating space between the underwear and the torso and further improving the effectiveness of the air-conditioning garment.
Specifically, for example, in the case of the above-mentioned embodiment 1, the circumferential portion of the lower end of the tubular body is connected to at least the location where the rubber cord 22 of the first sheet 2a is arranged, and the circumferential portion of the upper end of the tubular body is connected to the location where the rubber cord 22 of the third sheet 2c is arranged.

In addition, in each embodiment, the cases where each gap regulating sheet is sewn to the fabric have been described, but the method of attaching each gap regulating sheet to the fabric is not limited to sewing, and various common methods can be used.

In addition, in each embodiment, both ends of the elastic cord 22 are sewn to the front body of the clothing body 1, 101 via the spacing means 24. However, the purpose of the spacing means 24 is to prevent the fabric near where the elastic cord 22 is sewn from sticking to the body due to the tension of the elastic cord 22. Therefore, the spacing means 24 does not necessarily need to be in contact with the elastic cord 22; it is sufficient if it is located near where the elastic cord 22 is sewn.

(Third embodiment)
Next, an air-conditioning garment 310 according to a third embodiment will be described with reference to Figures 7 to 9. Note that components similar to those in the first and second embodiments are given the same reference numerals, and descriptions thereof will be omitted.

Figure 7(a) is a schematic front view of the air-conditioning garment 310 when the fan is operating, (b) is a schematic longitudinal cross-sectional view of the torso, and (c) is a partially enlarged view of (b).
As shown in FIG. 7( a ), when the fan (not shown) is operated, the air-conditioning garment 310 has an appearance similar to a down vest.

Next, a manufacturing method for the garment body 301 of the air-conditioning garment 310 of this embodiment will be described using Figure 8. Note that the manufacturing method for the garment body 301 described below will be limited to the torso portion of the garment body 301, and details such as the air leakage prevention means at the hem, the fan opening, the arm openings, and the seam allowances will not be described. Furthermore, the torso portion of the garment body 301 will be described as having a length of 50 cm and a circumference of 100 cm, with five elastic cords 22 used as a torso fitting means, and no air distribution means.

Figure 8 is a diagram illustrating the manufacturing method for the torso portion of the clothing body 301. (a) is a plan view of the fabric 311 that constitutes the clothing body 301, (b) is a plan view of the mesh fabric 321 that constitutes the clothing body 301, and (c) is a plan view of the mesh fabric 321 sewn to the fabric 311.

1. As the fabric for the torso of the clothing body 301, a fabric 311 measuring 50 cm in length and 100 cm in width with a pair of zippers 14 attached to both ends, a coarse mesh fabric 321 (space-regulating planar body) measuring 70 cm in length and 94 cm in width, and five thin elastic cords 22 with a natural length of 60 cm are prepared.
2. As shown in Figure 8(c), the mesh fabric 321 is positioned so that there is a 3 cm margin on each of the left and right edges of the fabric 311, and the top and bottom edges of the fabric 311 and mesh fabric 321 are aligned. Then, the mesh fabric 321 is left with equal amounts of slack at 10 cm vertical intervals, and sewn to the fabric 311 at six locations, including the top and bottom edges. In other words, the mesh fabric 321 is sewn to the fabric 311 at 10 cm vertical intervals, resulting in 4 cm of slack at every 10 cm vertical interval. Hereinafter, the 10 cm vertical strip-like portions of the fabric 311 to which the mesh fabric 321 is sewn will be referred to as the first slack strip 311a, second slack strip 311b, ..., fifth slack strip 311e, from bottom to top.
3. As shown in FIG. 9, elastic cords 22 are passed between the fabric 311 and the mesh fabric 321 of each of the first to fifth slack belt portions 311a to 311e, and both ends of each elastic cord 22 are sewn near the pair of zippers 14 via spacing means 24.

When the air-conditioned garment 310 using the garment body 301 manufactured as described above is worn and the fan is operated, positive pressure is generated inside the garment body 301, causing it to inflate, as shown in Figures 7(a) to (c). However, the portion of the mesh fabric 321 in contact with the elastic cord 22 adheres closely to the torso BD, so an upper planar body 321a is formed above the elastic cord 22 and a lower planar body 321b is formed below it, each having an approximately triangular cross section with the elastic cord 22 and the upper and lower sewn parts as vertices. In other words, the mesh fabric 321 comprises an upper planar body 321a (spacing regulation planar body) arranged above each elastic cord 22 and sloping downward from the outer periphery of the mesh fabric 321 toward the inner periphery, and a lower planar body 321b (spacing regulation planar body) arranged below the elastic cord 22 and sloping upward from the outer periphery of the mesh fabric 321 toward the inner periphery, with the inner end of the upper planar body 321a and the inner end of the lower planar body 321b being connected together.

In this embodiment, a coarse mesh fabric 321 is used for the clothing body 301, but of course, by combining it with a fine mesh fabric or the like, it is possible to provide the function of air distribution means as well.
In addition, in the areas corresponding to the second and fourth slack band portions 311b and 311d, it is possible to omit the mesh fabric 321 and the elastic cord 22 and construct the garment using only the fabric 311, or to omit only the elastic cord 22 without allowing slack in the mesh fabric 321.
