In recent years, when working in high temperatures, people have begun to wear air-conditioned clothing designed to cool the body by circulating outside air inside the clothing. For example, Patent Document 1 describes an air-conditioned garment that has a torso section that covers the user's torso and short-sleeve sections that cover parts of the user's arms.

Utility Model Registration No. 3222749

There is demand for air-conditioned clothing, both with and without sleeves. However, sleeveless clothing exposes the arms during work, so there is a risk that the body may not be protected from external influences during work.

To solve the above-mentioned problems of the conventional art, the present invention provides an air-conditioned garment in which some or all of the sleeves are made detachable, allowing safety during work to be maintained by the sleeves, and which has excellent cooling performance for the body whether the movable sleeves are attached or detached.

The present invention relates to an air-conditioned garment in which an air-generating device is detachably attached to one or more air intakes located at the bottom of the body, and in which a part or all of the sleeve is a removable movable sleeve portion, the movable sleeve portion is detachably joined to the body or a fixed sleeve portion fixed to the body via a detachment mechanism, the detachment mechanism being composed of a first connecting portion provided on the body or the fixed sleeve portion and a second connecting portion provided on the movable sleeve portion, and an air-leak suppression mechanism having circumferential elasticity is arranged at the opening of the body or the fixed sleeve portion on the side where it is joined to the movable sleeve portion.

The present invention provides an air-conditioned garment in which some or all of the sleeves are removable, so that safety can be maintained by the sleeves when performing work that requires safety, and which has excellent cooling performance for the body whether the movable sleeves are attached or removed.

FIG. 11A to 11C are explanatory diagrams relating to an example of a folding procedure for the movable sleeve portion.

The present inventors have conducted extensive research to solve the above-mentioned problems, and have found that by forming part or all of the sleeves as removable movable sleeves, removably joining the movable sleeves to the body or fixed sleeves fixed to the body via a detachment mechanism, and arranging an air leakage suppression mechanism that is stretchable in the circumferential direction at an opening of the body or fixed sleeves on the side where the movable sleeves are joined, it is possible to ensure safety during work by the sleeves, while improving the cooling performance for the body both when the movable sleeves are attached and when the movable sleeves are removed.
Specifically, safety can be ensured during work by joining the movable sleeve portion to the body or the fixed sleeve portion via a detachable mechanism.
Normally, when the movable sleeve is removed, the air taken in by the wind generating device flows out from the opening on the side of the body or fixed sleeve where the movable sleeve is joined, reducing the flow to the neck, chest, upper back, etc., which are areas that are effective for heat exchange because they sweat a lot and where large blood vessels are located, and reducing the cooling performance for the body. However, in the present invention, an air leakage suppression mechanism that is stretchable in the circumferential direction is placed in the opening on the side of the body or fixed sleeve where the movable sleeve is joined, thereby preventing the air taken in by the wind generating device from leaking out from the opening at the joint and ensuring the flow to the neck, chest, upper back, etc., thereby providing excellent cooling performance for the body.

Below, air-conditioning clothing according to one or more embodiments of the present invention will be described in conjunction with the drawings. However, the present invention is not limited to what is shown in these drawings.

Figure 1 is a schematic front view of an air-conditioned garment (long sleeves) according to one example of the present invention. Figure 2 is a schematic back view of the same air-conditioned garment. Figure 3 is a schematic front view of the same air-conditioned garment with the movable sleeves removed. Figure 4 is a schematic back view of the same air-conditioned garment with the movable sleeves removed. Figures 5 and 6 are partial schematic front views of the same air-conditioned garment with the movable sleeves removed. Figures 7 and 8 are partial schematic side views of the same air-conditioned garment. Figures 9 to 11 are schematic cross-sectional views of the joint between the body and the movable sleeves in the air-conditioned garment. Figure 12 is a schematic cross-sectional view of the location of the chest pocket in the air-conditioned garment.

In the air-conditioned garment 1, the sleeves 2 that cover the arms are joined to the body 4 at the shoulders, and the sleeves 2 form movable sleeve sections 3 that can be removed in their entirety. A detachment mechanism 5 is provided at the joint between the movable sleeve section 3 and the body 4, and the movable sleeve section 3 is detachably joined to the body 4 via the detachment mechanism 5.

In this embodiment, the attachment/detachment mechanism 5 is disposed on the back side (body side) of the body 4. In this case, as shown in Figs. 5 and 7, a slit 7 may be provided at the bottom of the opening of the body 4 and at the top of the joining part of the front body 41 and the back body 42. When the slit 7 is opened, the attachment/detachment mechanism 5 can be seen as shown in Fig. 8, and opening the slit 7 makes it easier to attach and detach the movable sleeve 3.

The detachment mechanism may be located on the back side (closer to the human body) of the body or on the front side (opposite the human body), but from an aesthetic point of view, it is preferable to place it on the back side (closer to the human body) of the body. Also, it is usually desirable to place the detachment mechanism near the opening of the joint between the movable sleeve and the body or fixed sleeve, for example, in an area 0.1 to 10.0 cm away from the end of the opening.

The detachment mechanism 5 is composed of a first connecting part 51 provided on the body 4 and a second connecting part 52 provided on the movable sleeve part 3. The first connecting part 51 can be attached to the body 4 by, for example, sewing. The second connecting part 52 can be attached to the movable sleeve part 3 by, for example, sewing.

The first connecting part and the second connecting part are not particularly limited as long as they can be joined to each other in a detachable manner, and can be configured, for example, with a fastener (also called a line fastener), a hook-and-loop fastener, a snap button, etc. From the viewpoint of increasing the air pressure inside the garment, it is preferable to configure them with a fastener, a hook-and-loop fastener, etc., and it is more preferable to configure them with a fastener because of their excellent washing durability. Examples of fasteners include metal fasteners, resin fasteners, Vislon (registered trademark) fasteners, etc. Examples of hook-and-loop fasteners include polyester Velcro (registered trademark), etc. Examples of snap buttons include metal snap buttons, resin snap buttons, etc.

Figure 9 shows the case where the detachment mechanism 5, i.e., the first connecting portion 51 and the second connecting portion 52, are configured with a zipper, Figure 10 shows the case where the detachment mechanism 5, i.e., the first connecting portion 51 and the second connecting portion 52, are configured with a hook-and-loop fastener, and Figure 11 shows the case where the detachment mechanism 5, i.e., the first connecting portion 51 and the second connecting portion 52, are configured with a snap button.

An air leakage suppression mechanism 6 is disposed in the opening of the body 4 on the side where it joins with the movable sleeve 3. The air leakage suppression mechanism 6 is stretchable in the circumferential direction, and the diameter of the opening of the body 4 on the side where it joins with the movable sleeve 3 can be adjusted. Specifically, the air leakage suppression mechanism 6 can shrink the diameter of the opening of the body 4 so that it fits closely to the wearer's body. In addition, if necessary, it can be stretched to the same size as the circumferential direction of the body 4 at the air leakage suppression mechanism attachment position. When the air leakage suppression mechanism is shrunk, specifically when it is shrunk so that it fits closely to the body, it is preferable that the attachment/detachment mechanism does not shrink. This results in a good appearance and is less likely to impede arm movement.

The air leakage prevention mechanism may be placed on the back side (closer to the human body) of the body or on the front side (opposite the human body), but from the standpoint of air leakage prevention and aesthetics, it is preferable to place it on the back side (closer to the human body) of the body.

The air leakage suppression mechanism may be positioned closer to the cuff than the detachable mechanism (first connecting portion) or farther from the cuff, but from the viewpoint of improving cooling of the chest, neck, and upper back, it is preferable that the air leakage suppression mechanism be positioned farther from the cuff (i.e., closer to the center of the body) than the detachable mechanism. It is more preferable that at least a part of the air leakage suppression mechanism is positioned in the area covering the clavicle to the humerus. When the air leakage suppression mechanism is positioned in the area covering the acromion to the humerus, it does not hinder the movement of the elbow joint and can prevent air leakage.

The air leakage suppression mechanism 6 is composed of a main body 61 attached to the back side of the body 4, a string-passing part 62 provided at the non-fixed end (end not attached to the body) of the main body 61, and a string 63 inserted into the string-passing part 62, and the opening diameter of the string-passing part 62 can be adjusted by the string 63. The main body 61 is preferably cylindrical so that the arm can pass through it. The main body 61 can be attached to the body 4, for example, by sewing. When the movable sleeve part is removed, the opening diameter of the string-passing part 62 is reduced by tightening the string 63 until it comes into close contact with the human body, and the opening diameter of the opening of the body 4 is also reduced until it comes into close contact with the human body, thereby suppressing air leakage from the opening of the body 4. When the string 63 is tightened, the opening diameter of the string-passing part 62 is smaller than the circumference of the attachment/detachment mechanism 5. In addition, when the movable sleeve portion is joined to the body, the opening diameter of the string-passing portion 62 can be expanded to the maximum, for example, to the same size as the circumferential direction of the body 4 at the attachment position of the main body portion 61, by loosening the string 63. Note that when the movable sleeve portion is joined to the body, it is not necessary to loosen the string 63, if necessary.

The main body 61 may be made of a stretchable fabric that is stretchable in the circumferential direction, or may be made of a non-stretchable fabric. When the main body 61 is made of a stretchable fabric, the main body 61 alone may function as an air leakage suppression mechanism by adjusting the stretchability of the stretchable fabric without providing a string-passing section and a string. From the viewpoint of a good wearing comfort and easy adjustment of the opening diameter as needed, it is preferable to make the main body 61 of a non-stretchable fabric and/or a stretchable fabric and provide a string-passing section 62 and a string 63. From the viewpoint of stretchability, a rubber string can be preferably used as the string 63. In the main body 61, the stretchable fabric is preferably one that has an elongation rate of 10% in the body width direction (circumferential direction) measured under conditions of a load of 17.6 N and a tensile speed of 200 mm/min based on JIS L 1096 8.14.1 A method.

When the air leakage prevention mechanism is composed of only the main body, it can be provided, for example, by attaching a stretchable fabric that is stretchable in the longitudinal direction to the opening on the side where the fixed sleeve part or the movable sleeve part of the body is joined so that the longitudinal direction coincides with the circumferential direction of the detachable part.

9 to 11, the air leakage suppression mechanism 6 is composed of a main body 61 attached to the back side of the body 4, a string-passing part 62 provided at the non-fixed end of the main body 61, and a string 63 inserted into the string-passing part 62. The main body 61 is attached to the back side of the body 4 by sewing so that the string-passing part 62 is located farther from the opening end of the body 4 and inside the garment than the detachment mechanism 5 (specifically, the first connecting part 51). The air leakage suppression mechanism 6, specifically the main body 61, is not particularly limited, but it is desirable to attach it to the back side of the body 4 by sewing at a position 0.1 cm to 30.0 cm away from the detachment mechanism 5 (specifically, the first connecting part 51) and close to the center of the body. The main body may be attached to the back side of the body by sewing so that the string-passing part comes out of the opening on the side where the body or the movable sleeve part of the fixed sleeve part is joined. In this case, too, the opening diameter of the string passage can be reduced by tightening the string so that it fits closely to the human body. In this case, the main body part protruding from the opening can function as a sleeve.

As shown in FIG. 6, tightening the string 63 reduces the opening diameter of the string-passing section 62. On the other hand, as shown in FIG. 5, loosening the string 63 allows the opening diameter of the string-passing section 62 to be expanded to the same size as the circumferential direction of the body 4 at the attachment position of the main body section 61.

As shown in Figures 3, 5, and 6, the two string holes 64 of the string passage section 62 are located on the front body side of the main body section 61, close to the chest area. The opening diameter of the string passage section 62 can be adjusted by adjusting the tightening of the string 63 coming out of the string holes 64. Also, the string 63 may be kept in a contracted state using a stopper.

The air-conditioned garment 1 may further have a chest pocket 8 that is disposed on the chest of the front body 41, opens to the front side (opposite the human body), and has a bag portion sewn to the back side (toward the human body). The chest pocket 8 may have two garment-side string holes 81 through which the string 63 passes, on the side closer to the string hole 64. The garment-side string holes 81 are disposed on the human body side of the chest pocket 8. The distance between the two garment-side string holes is not particularly limited, but may be, for example, 0.5 cm or more and 10 cm or less. Inside the bag of the chest pocket 8, a hole cover pocket 82 that covers the garment-side string holes 81 may be provided.

Figure 13 is a schematic front view of the arrangement of the chest pocket of an example of the air-conditioned garment of the present invention. Figure 14 is a schematic cross-sectional view of the same. Instead of the chest pocket 8, the air-conditioned garment 1 may have a chest pocket 18, which is arranged on the chest of the front body 41, opens on the front side (the opposite side of the human body), and has a bag part sewn (the opposite side of the human body) as shown in Figure 13. In this case, as shown in Figure 14, the front body 41 to which the chest pocket 18 is sewn can have two garment-side string holes 181 through which the string 63 passes. The garment-side string holes 181 are arranged within the range covered by the chest pocket bag of the front body 41 to which the chest pocket is sewn. The distance between the two garment-side string holes is not particularly limited, but may be, for example, 0.5 cm to 10 cm.

It is preferable to attach a stopper 65 to the string 63 that passes through the string hole 64 and the garment side string hole 81 (or the garment side string hole 181) and is located inside the chest pocket 8. When tightening the opening of the body at the joint between the body 4 and the movable sleeve 3, specifically the string hole 62, a part of the string 63 can be removed from the chest pocket 8 and the string 63 can be tightened while wearing the garment. When the air leakage suppression mechanism 6 (string hole 62) is to be shortened, the string 63 that passes through the stopper 65 is pulled, and the stopper 65 is stopped when the required length is reached, thereby maintaining the air leakage suppression mechanism 6 (string hole 62) in a shortened state, for example, in close contact with the human body.

Figure 15 is a partial schematic front view of an air-conditioned garment according to an example of the present invention. As shown in Figure 15, a string stop loop 9 for passing the string end can be provided inside the chest pocket 8. This can prevent the end of the pulled string 63 from jumping out of the chest pocket 8 when the air leakage suppression mechanism 6 (string passage part 62) is contracted. The string stop loop 9 can be provided inside the chest pocket 8 between the opening of the chest pocket 8 and the bottom of the chest pocket 8, with a length that does not extend outside the chest pocket 8 and a width of 10 cm or less. Although not shown, in the case of a chest pocket 18 that opens on the front side (the opposite side of the human body) and has a bag part sewn (the opposite side of the human body), the string stop loop can be provided inside the chest pocket between the opening of the chest pocket and the bottom of the chest pocket, with a length that does not extend outside the chest pocket and a width of 10 cm or less.

It is preferable that the air-conditioned garment 1 further has a movable sleeve storage pocket 10 arranged on the back side of the chest of the front body 41. By storing the removed movable sleeve 3 in the movable sleeve storage pocket 10, the space between the human body and the garment becomes larger, and air taken in by a wind generating device such as a fan passes through and easily flows to the chest and neck. The movable sleeve storage pocket 10 can be arranged in a position that contacts the chest when the movable sleeve 3 is stored. It is also preferable that the movable sleeve storage pocket 10 has a thickness of 0.5 cm or more when the movable sleeve 3 is stored. Here, the thickness is measured by spreading the garment on a horizontal table, storing the movable sleeve in the movable sleeve storage pocket, and measuring the height of the maximum convex point of the movable sleeve storage pocket under no load.

It is desirable that the left and right movable sleeve storage pockets 10 are separated from each other. It is preferable that the left and right movable sleeve storage pockets 10 are not in contact with each other, but are in contact with the left and right pectoral muscles, respectively. The movable sleeve storage pocket 10 is placed closer to the human body than the chest pocket 8, and may partially overlap with the chest pocket 8. The movable sleeve storage pocket 10 is not particularly limited, but for example, it is preferable that the width is 1 cm to 20 cm and the gusset is 0.5 cm to 10 cm, and the length can be arbitrarily determined according to the width and gusset size.

In air-conditioned clothing, the length of the sleeves is not particularly limited, and examples include short sleeves, three-quarter sleeves, and long sleeves. The movable sleeve portion may be the entire sleeve or a part of the sleeve. In addition, the sleeve may be joined to the body at the shoulder, or the sleeve may not be joined to the body at the shoulder and may have a joint in the part covering the arm.

In the air-conditioned garment 1, the front body 41 is divided into left and right parts, and the left and right front body parts may be connected by a connecting member 11 so that they can be opened and closed. From the viewpoint of increasing the air pressure inside the garment, it is preferable to use, for example, a zipper or a hook-and-loop fastener as the connecting member 11. The air-conditioned garment 1 further has a collar 12 and a hem 13. From the viewpoint of preventing air leakage, the hem 13 may be made of a stretchable material such as an elastic band.

The air-conditioned garment 1 may have an abdominal pocket 14 that is placed on the abdominal area of the front body 41, opens on the front side (opposite the human body), and has a bag portion sewn to the back side (toward the human body). The opening of the abdominal pocket 14 may be connected by a connecting member 15 so that it can be opened and closed. For example, a zipper or a hook-and-loop fastener may be used as the connecting member 15.

The air-conditioned garment 1 is provided with a pair of air intakes 22 arranged symmetrically on the sides of the lower part of the back body, and a wind generator 23 that is detachably connected to each of the air intakes 22 and takes in air from the outside into the garment. It also includes a power supply unit 24 that supplies power to the wind generator 23, and a power supply cable 26 for connecting the wind generator 23 and the power supply unit 24. The air-conditioned garment 1 of this embodiment has a pair of air intakes 22 from the viewpoint of improving the aesthetic appearance and the air flow inside the garment, but the number of air intakes may be one or three or more. A resin fixing ring is provided on the periphery of the air intake 22, and a wind generator 23 such as a fan is fixed to the air intake 22 via the fixing ring. The fixing ring can be made of resin such as silicone resin (silicone), polypropylene, polyester, polyethylene, etc.

The air intake may be located at the bottom of the front body, but it is preferable to place it at the bottom of the back body to make it easier to cool the upper back.

The wind generator 23 draws air from the outside into the garment and forcibly creates a flow of air in the space between the body (or underwear) and the garment. There is no particular limitation on the wind generator 23, and for example, a fan can be used. There is no particular limitation on the fan, and for example, the same fan as that used in conventional air-conditioned garments can be used.

The power supply device 24 is not particularly limited, but may be any portable power source. For example, a rechargeable battery or a dry cell may be used, and it is preferable to use a rechargeable battery from the viewpoint of repeated use. As a rechargeable battery, for example, a lithium ion secondary battery may be used. When wearing the air-conditioned garment 1, the power supply device 24 may be stored in a rear body storage pocket 27 provided in the lower center part of the back side of the rear body. If necessary, the power supply device 24 may be stored in an abdominal storage pocket 28 provided on the back side of the abdominal part of the front body.

Figure 16 is a partial schematic front view of an air-conditioned garment (long sleeves) of another example of the present invention turned inside out. In the air-conditioned garment 101 of this embodiment, the sleeves 102 are joined to the body 4 at the shoulders, and a portion of the sleeves 102 forms a removable movable sleeve portion 103. The sleeves 102 consist of fixed sleeve portions 116 fixed to the body 4 and the movable sleeve portion 103, and the movable sleeve portion 103 is detachably joined to the fixed sleeve portion 116 via a detachment mechanism 5. The air leakage suppression mechanism 106 can be provided at the opening on the side of the fixed sleeve portion 116 that joins with the movable sleeve portion 103.

The detachment mechanism 5 is composed of a first connecting part 51 provided on the fixed sleeve part 116 and a second connecting part 52 provided on the movable sleeve part 103. The first connecting part 51 can be attached to the fixed sleeve part 116 by, for example, sewing. The second connecting part 52 can be attached to the movable sleeve part 103 by, for example, sewing.

The air leakage suppression mechanism 106 is composed of a main body 61 attached to the back side of the fixed sleeve 116, a string-passing part 62 provided at the non-fixed end of the main body 61, and a string 63 inserted into the string-passing part 62. The main body 61 is attached to the back side of the fixed sleeve 116 by sewing so that the string-passing part 62 is located farther from the opening end of the fixed sleeve 116 and inside the garment than the attachment/detachment mechanism 5 (specifically, the first connecting part 51). The air leakage suppression mechanism 106, specifically the main body 16, is not particularly limited, but it is desirable to attach it to the back side of the fixed sleeve 116 by sewing at a position 0.1 cm to 30.0 cm away from the attachment/detachment mechanism 5 (specifically, the first connecting part 51) and close to the center of the body.

In the air leakage suppression mechanism 106, when the string 63 is tightened, the opening diameter of the string-passing section 62 becomes smaller, and the opening diameter of the opening of the fixed sleeve section 116 can be reduced to the point where it fits closely to the wearer's body. By loosening the string 63, the opening diameter of the string-passing section 62 can be expanded to the same size as the circumferential direction of the fixed sleeve section 116 at the attachment position of the main body section 61.

The air-conditioned garment 101 can be configured in the same way as the air-conditioned garment 1 described above, except that the sleeves are made up of a fixed sleeve portion and a movable sleeve portion, the first connecting portion of the detachment mechanism is provided in the fixed sleeve portion, and the air leakage suppression mechanism is provided in the fixed sleeve portion, and therefore repeated explanations will be omitted.

Figure 17 is a partial schematic front view of an air-conditioned garment (long sleeves) of another example of the present invention turned inside out. In the air-conditioned garment 201 of this embodiment, the sleeves are not joined to the body at the shoulders, i.e., the body 4 and the sleeves 202 are integrated (i.e., sewn together), and a part of the sleeve 202 forms a removable movable sleeve section 203. The sleeve 202 consists of a fixed sleeve section 216 integrated with the body 4 and a movable sleeve section 203, and the movable sleeve section 203 is detachably joined to the fixed sleeve section 216 via a detachment mechanism 5. The air leakage suppression mechanism 206 can be provided at the opening on the side of the fixed sleeve section 216 that joins with the movable sleeve section 203.

The detachment mechanism 5 is composed of a first connecting part 51 provided on the fixed sleeve part 216 and a second connecting part 52 provided on the movable sleeve part 203. The first connecting part 51 can be attached to the fixed sleeve part 216 by, for example, sewing. The second connecting part 52 can be attached to the movable sleeve part 203 by, for example, sewing.

The air leakage suppression mechanism 206 is composed of a main body 61 attached to the back side of the fixed sleeve 216, a string-passing section 62 provided at the non-fixed end of the main body 61, and a string 63 inserted into the string-passing section 62. The main body 61 is attached to the back side of the fixed sleeve 216 by sewing so that the string-passing section 62 is located farther from the opening end of the fixed sleeve 216 and inside the garment than the attachment/detachment mechanism 5 (specifically, the first connecting section 51). The air leakage suppression mechanism 206, specifically the main body 61, is not particularly limited, but it is desirable to attach it to the back side of the fixed sleeve 216 by sewing at a position 0.1 cm to 30.0 cm away from the attachment/detachment mechanism 5 (specifically, the first connecting section 51) and close to the center of the body.

In the air leakage suppression mechanism 206, when the string 63 is tightened, the opening diameter of the string-passing section 62 becomes smaller, and the opening diameter of the opening of the fixed sleeve section 216 can be reduced to the point where it fits closely to the wearer's body. By loosening the string 63, the opening diameter of the string-passing section 62 can be expanded to the same size as the circumferential direction of the fixed sleeve section 216 at the attachment position of the main body section 61.

The air-conditioned garment 201 can be configured in the same way as the air-conditioned garment 1 described above, except that the sleeves (specifically, the fixed sleeve portions) are integrated with the body, the sleeves consist of fixed and movable sleeve portions, the first connecting portion of the detachment mechanism is provided in the fixed sleeve portions, and the air leakage suppression mechanism is provided in the fixed sleeve portions, and therefore repeated explanations will be omitted.

The fabric used for the air-conditioned garment is not particularly limited, and woven fabrics and knitted fabrics can be used. From the viewpoint of suppressing ventilation in the cross-sectional direction of the fabric, woven fabrics are preferable. The above-mentioned fabric is not particularly limited, and may be a single weave structure or a double weave structure. For example, plain weave, twill weave, satin weave, variable plain weave, variable twill weave, variable satin weave, variegated weave, patterned weave, single overlap weave, double weave, multiple weave, warp pile weave, weft pile weave, and twill weave can be mentioned. The fiber constituting the fabric is not particularly limited, and for example, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate, polyurethane fibers, polyamide fibers, acetate fibers, cotton fibers, rayon fibers, ethylene vinyl alcohol fibers, and nylon fibers can be used. The fabric is not particularly limited, but for example, the basis weight is preferably in the range of 20 to 300 g/m ² , and more preferably in the range of 50 to 250 g/m ² . If the basis weight is within the above range, it has the advantages of being durable, light and easy to move around in.

The present invention will be described in more detail below using examples. Note that the present invention is not limited to the following examples.

Example 1
Fabric (plain weave, 77% polyester fiber, 23% cotton, 156 g/ ^m2 weight) was used for the front and back body, collar and sleeves. The air intake was circular with a diameter of 10 cm. The fixing ring of the air intake was made of silicone resin. A 10 cm diameter fan (manufactured by San-Etsu Co., Ltd., product name "Fan Set Thin Type RD9710A", blade diameter 80 mm, number of blades 5, power supply 7 V, 2 A) was used as the wind generating means. A lithium ion battery (manufactured by San-Etsu Co., Ltd., product name "Lithium Ion Battery RD9870AJ") was used as the power supply. A cable (manufactured by San-Etsu Co., Ltd., product name "Fan Set Thin Type RD9710A") was used as the power supply cable, zippers (YKK Corporation's 3CFOLM91X6-7386014J (right sleeve), 3CFOLM91X6-7785972J (left sleeve)) were used for the attachment/detachment mechanism (first connection part and second connection part), woven fabric (plain weave, 77% polyester fiber, 23% cotton, basis weight 156 g/ ^m2 ) was used for the main body of the air leakage suppression mechanism, and elastic cord (YE25H manufactured by YKK Corporation) was used for the strings, and a blouson-type (long-sleeved) air-conditioned garment 1 (JASPO standard L size) as shown in Figures 1 to 9 was produced. All of the sleeves were movable. The attachment/detachment mechanism and the main body of the air leakage suppression mechanism were attached to the garment body by sewing.

Example 2
A blouson-type (long-sleeved) air-conditioned garment 1 (JASPO standard L size) with all of the sleeves being movable was produced in the same manner as in Example ¹ , except that a movable sleeve storage pocket (length 23 cm, width 7.5 cm, gusset 4.0 cm) made of woven fabric (plain weave, 77% polyester fiber, 23% cotton, basis weight 156 g/m2) was provided on the inside of the front body. As shown in Fig. 18, the movable sleeve was folded four times so that the cuff and the second connecting part of the attachment/detachment mechanism overlap, and the thickness of the folded movable sleeve when stored in the movable sleeve storage pocket was 3.8 cm. Here, the thickness was measured by spreading the garment on a horizontal table, storing the movable sleeve in the movable sleeve storage pocket, and measuring the height of the maximum convex point of the movable sleeve storage pocket under no load.

(Comparative Example 1)
A blouson-type (long-sleeved) air-conditioned garment 1 (JASPO standard L size) with all of the sleeves movable was produced in the same manner as in Example 1, except that no air leakage suppression mechanism was provided.

The air-conditioned garments of Examples 1 and 2 and Comparative Example 1 were worn by an anthropomorphic mannequin (Shichisaisha, product name: "Average Japanese Body Size Dummy") fitted with an anemometer (Japan Kanomax Co., Ltd., "ANEMOMASTER MODEL 6004"); the fan was turned on, and the air speed was measured with the anemometer. The anemometer was positioned so that the sensor was located 13 cm from the top of the manubrium (chest) and at the chin. The results are shown in Table 1 below.

As can be seen from the results in Table 1, in Examples 1 and 2, the air leakage suppression mechanism is provided, and when the movable sleeves are removed, by tightening the air leakage suppression mechanism, air can be transferred to the chest and neck at approximately the same level as when the movable sleeves are attached, and the cooling performance for the body is good. Also, in the case of Example 2, in which the movable sleeves are stored in the storage pocket, air can be transferred to the chest and neck more effectively than in Example 1, which does not have a movable sleeve storage pocket.
On the other hand, in the case of comparison example 1, which does not have an air leakage prevention mechanism, when the movable sleeve portion is removed, air cannot be effectively transported to the chest and neck, making it difficult to achieve cooling performance for the body.
