The garment of the present invention will be described with reference to the drawings. Below, a jumper-type upper-body garment will be used as an example of the garment of the present invention. However, the present invention is not limited to this embodiment, and modifications can be made as appropriate without departing from the spirit of the invention.

<1 Overall structure of the garment and garment body>
Fig. 1(a) is a front view of the garment 1, Fig. 1(b) is a back view of the garment 1, and Fig. 1(c) is a back view of the garment 1 with a blower 40 attached. Fig. 2 is a schematic diagram of the inner side of the garment 1. Fig. 3(a) is a cross-sectional view taken along line IIIa-IIIa in Fig. 2, and Fig. 3(b) is a cross-sectional view taken along line IIIb-IIIb in Fig. 2. Fig. 4(a) is a cross-sectional view taken along line IVa-IVa in Fig. 2, and Fig. 4(b) is a cross-sectional view taken along line IVb-IVb in Fig. 2.

As shown in Figure 1(a), the "up-down direction" (sometimes referred to as the "vertical direction") and "left-right direction" (sometimes referred to as the "horizontal direction") of garment 1 are defined relative to the wearer. The "center line O of garment 1" refers to the "straight line passing through the center of garment 1 in the left-right direction." The "inner surface" refers to the surface facing the wearer.

The garment 1 comprises a garment body 10, a spacer 20, a holder 30, an air blower 40, and a power supply 50. The spacer 20 is held to the garment body 10 by the holder 30. The air blower 40 is a fan that is detachably attached to the garment body 10. The power supply 50 is an electrical means for driving the air blower 40 and comprises a power source 51 and a cable 52. The power source 51 and the air blower 40 are electrically connected by the cable 52. By activating the air blower 40, outside air is drawn into the garment body 10, cooling the wearer P's body.

<1-1 Clothes itself>
The garment body 10 will be described mainly with reference to Figure 1. The garment body 10 comprises a body portion 11, sleeve portions 12, a collar portion 13, and a drawstring portion 14. The body portion 11 consists of a front body portion 111 and a back body portion 112. The sleeve portions 12 are connected to the sides of the body portion 11 by stitching. The collar portion 13 is connected to the upper end of the body portion 11 by stitching. The drawstring portion 14 is connected to the lower end of the body portion 11 by stitching. The garment body 10 is made of a flexible material that does not allow gas to easily pass from inside the garment body 10 to outside the garment body 10. The material of the garment body 10 is, for example, polyester.

The drawstring portion 14 contains a stretchable material such as rubber. This allows the drawstring portion 14 to be narrowed so that its width is smaller than the width of the body portion 11. The drawstring portion 14 preferably fits closely to the body of the wearer P.

A plurality of circular through-holes 15 (two in Figure 1(b)) are provided at intervals in the left-right direction near the waist of the back body 112. As shown in Figure 1(c), a blower 40 is attached to each of the plurality of through-holes 15. Note that the through-holes 15 may be formed in the front body 111 instead of the back body 112. Alternatively, the through-holes 15 may be formed in the front body 111 in addition to the back body 112.

<1-2 Spacer and holding part>
The spacers 20 and the retaining portion 30 will be described mainly with reference to Figures 2 to 4. The spacers 20 include back body spacers 21 (21a to 21d) and sleeve spacers 22. The back body spacers 21 are arranged on the inner surface of the back body 112 near the collar and back. The sleeve spacers 22 are arranged near the shoulders from the inner surface of the back body 112 to the inner surface of the sleeves 12. As shown in Figures 3 and 4, the provision of the spacers 20 ensures that spaces S through which air can flow are secured between the back body 112 and the wearer P, and between the sleeves 12 and the wearer P.

The spacer 20 has, for example, breathable, cushioning, non-breathable, and/or cooling properties. The spacer 20 can be made, for example, from a cushioning and non-breathable material, a cushioning and breathable material (e.g., sponge), or a non-breathable ice pack. The shape of the spacer 20 is, for example, cylindrical (including semi-cylindrical; preferably cylindrical or semi-cylindrical), rectangular, or spherical. In this embodiment, the spacer 20 is composed of a cylindrical member made of a cushioning and non-breathable material. The axial length (height) of this spacer 20 is longer than the diameter.

The retaining portion 30 may be configured, for example, as a pocket or hook-and-loop fastener, as long as it can hold the spacer 20 so that it does not fall off the garment body 10. If the retaining portion 30 is a pocket, it is preferably made of a breathable material such as mesh. It is also preferable that the retaining portion 30 be able to removably hold the spacer 20 on the garment body 10.

The back body spacer 21 includes two first spacers 21a, 21b and two second spacers 21c, 21d. The two second spacers 21c, 21d are positioned lower than the two first spacers 21a, 21b. In the embodiment shown in Figure 2, the two first spacers 21a, 21b and the two second spacers 21c, 21d are all positioned so that their axial directions are parallel to the vertical direction.

The two first spacers 21a, 21b and the two second spacers 21c, 21d are preferably arranged closer to the center line O in the left-right direction than the outer edge (i.e., the edge farther from the center line O) of the through hole 15 (blower device 40), and more preferably closer to the center line O than the inner edge (i.e., the edge closer to the center line O) of the through hole 15 (blower device 40).

Two first spacers 21a, 21b are arranged directly below the collar portion 13, spaced apart in the left-right direction. First spacer 21a and first spacer 21b at least partially overlap in the up-down direction. Therefore, a first vertical flow path L1 extending in the up-down direction is formed between first spacer 21a and first spacer 21b.

The two second spacers 21c and 21d are arranged spaced apart in the left-right direction. The second spacers 21c and 21d at least partially overlap in the up-down direction. Therefore, a second vertical flow path L2 extending in the up-down direction is formed between the second spacers 21c and 21d.

Note that the phrase "at least partially overlapping in the vertical direction" means that the upper end of one back body spacer 21 is positioned higher than the lower end of the other back body spacer 21.

The right-side second spacer 21c is positioned vertically spaced apart from the right-side first spacer 21a and at least partially overlaps the right-side first spacer 21a in the left-right direction. Therefore, a first horizontal flow path T1 extending in the left-right direction is formed between the right-side first spacer 21a and the right-side second spacer 21c.

The left-side second spacer 21d is positioned vertically spaced apart from the left-side first spacer 21b and at least partially overlaps the left-side first spacer 21b in the left-right direction. Therefore, a second horizontal flow path T2 extending in the left-right direction is formed between the left-side first spacer 21b and the left-side second spacer 21d.

Note that the phrase "at least partially overlapping in the left-right direction" means that at least one of the left and right ends of one back body spacer 21 is located between the right and left ends of the other back body spacer 21.

The two first spacers 21a, 21b may be the same size or different sizes. In one embodiment, the two first spacers 21a, 21b are arranged symmetrically with respect to the center line O. In one embodiment, the two first spacers 21a, 21b have the same vertical length, and are arranged at the same vertical height (i.e., the upper ends of the two first spacers 21a, 21b and the lower ends of the two first spacers 21a, 21b are respectively at the same height).

Similarly, the two second spacers 21c, 21d may be the same size or different sizes. In one embodiment, the two second spacers 21c, 21d are arranged symmetrically with respect to the center line O. In one embodiment, the two second spacers 21c, 21d have the same vertical length, and are arranged at the same height in the vertical direction (i.e., the upper ends of the two second spacers 21c, 21d and the lower ends of the two second spacers 21c, 21d are respectively at the same height).

The first spacers 21a, 21b and the second spacers 21c, 21d may be the same size or different sizes.

<2 Features>
FIG. 5 is a schematic diagram showing the flow of gas within the garment 1. As shown in FIG. 5, when the air blower 40 is driven, gas is drawn into the garment body 10 from the outside. Some of the gas rises through the outside of the second spacers 21c and 21d, and some of the gas rises through the second vertical flow path L2. Then, some of the gas rises through the outside of the first spacers 21a and 21b, and some of the gas flows into the first horizontal flow path T1 and the second horizontal flow path T2. The gas that passes through the second vertical flow path L2, the first horizontal flow path T1, and the second horizontal flow path T2 then passes through the first vertical flow path L1 and is discharged from the collar. Some of the gas also flows into the sleeves 12.

In the garment 1 of the present invention, a rear body spacer 21 is provided on the inner surface of the back body 112. This ensures that a space S through which gas can flow is maintained between the wearer P and the back body 112, even when the wearer P bends forward. In particular, the back body 112 tends to fit closely to the wearer P from the back to the waist when the wearer P bends forward. However, by providing the second spacers 21c and 21d near the back, a space S through which gas can flow is maintained from the back to the waist. This configuration ensures that the flow of gas is not impeded within the garment body 10, allowing the wearer P to be cooled efficiently.

The provision of the first vertical flow path L1 and the second vertical flow path L2 allows gas to circulate smoothly upward. This increases the amount of gas discharged from the collar of the garment body 10, actively cooling the neck of the wearer P. In particular, the provision of the first spacers 21a, 21b at the collar prevents the collar of the back body 112 from coming into close contact with the wearer P, ensuring a space S between the collar and the wearer P through which gas can circulate. This further increases the amount of gas discharged from the collar, thereby further cooling the neck of the wearer P. Furthermore, because the human neck has large blood vessels running close to the skin, actively cooling the neck is thought to be effective in lowering the body temperature of the wearer P.

Some of the gas that passes outside the second spacers 21c and 21d passes through the first horizontal flow path T1 and the second horizontal flow path T2 and enters the first vertical flow path L1. As a result, the amount of gas passing through the first vertical flow path L1 can be increased.

By arranging the rear body spacer 21 vertically, the first vertical flow path L1 and the second vertical flow path L2 are also vertically long. This allows gas to flow smoothly upward.

By locating the back body spacer 21 closer to the center line O than the through-hole 15 (air blower 40), gas can be concentrated near the center of the garment 1.

By providing sleeve spacers 22 at the shoulders of the sleeves 12, gas can be circulated sufficiently within the sleeves 12.

Because the spacer 20 is made of a tubular member with cushioning properties, the spacer 20 collapses appropriately when it comes into contact with the wearer P, minimizing any discomfort felt when coming into contact with the spacer 20.

Because the spacer 20 is made of a cooling material, the gas inside the garment body 10 can be cooled.

<3. Modified Examples>
(1) The right-side first spacer 21a and the right-side second spacer 21c do not have to overlap in the left-right direction. That is, the right-side first spacer 21a may be disposed closer to the center line O than the right-side second spacer 21c, or may be disposed farther from the center line O than the right-side second spacer 21c. Similarly, the left-side first spacer 21b and the left-side second spacer 21d do not have to overlap in the left-right direction. That is, the left-side first spacer 21b may be disposed closer to the center line O than the left-side second spacer 21d, or may be disposed farther from the center line O than the left-side second spacer 21d.

(2) The garment body 10 does not have to have a through-hole 15 (air blower attachment portion), and the air blower 40 does not have to be attached to the garment body 10. For example, as shown in FIG. 6(a), the air blower 40 may be attached to a holding member 60 such as a waist belt, and as shown in FIG. 6(b), the wearer P may wear the holding member 60 and insert the air blower 40 into the garment 1, thereby drawing outside air into the garment 1.
