Description

[Technical Field]

[0001] The present disclosure relates to an upper garment and an upper garment equipped with an air blower including the same. [Background technology]

[0002] Conventionally, there have been known jackets equipped with a blower that draws in outside air. When wearing such a jacket, if the back of a chair or the like is placed close to the back of the person wearing it, the blower is likely to press against the back. For example, Patent Document 1 listed below discloses a garment in which a pair of mounting holes are provided at the bottom of the garment body near the widthwise ends, and a stretchable section is provided that extends in the length direction of the garment body, inside the widthwise direction of the garment body from the blowers and below a height position corresponding to the width of the garment body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-33653 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the garment described in Patent Document 1, the air blowers are provided at the bottom of the garment body. Therefore, for example, when a person sits on a backrest that curves around the waist to surround the back side of the waist, there is a concern that the left and right air blowers may easily interfere with the backrest even when they move outward in the width direction. Furthermore, because the air blowers are located at a height near the waist, there is a concern that the air blowers that move outward in the width direction may easily interfere with the arms, etc., when swinging arms while walking or performing various tasks.

[0005] The present disclosure has been made in consideration of the above-mentioned situation, and aims to provide an upper garment that can reduce interference between the air blower attached to the mounting hole and the back, arms, etc., and an upper garment equipped with such an air blower. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, configuration 1 of the upper garment disclosed herein is an upper garment having mounting holes on both the left and right sides of the back body to which a blower for taking in outside air can be attached, and the mounting holes on both the left and right sides are arranged so that their respective hole centers are located above the vertical center from the lower edge of the armhole of the upper garment to the lower end of the upper garment, and each of the left and right sides of the back body is provided with a pleated folding portion that extends in the vertical direction and is freely foldable and unfoldable, and when unfolded, moves each of the mounting holes on both the left and right sides outward in the lateral direction.

[0007] The following description of the embodiments discloses that the upper garment according to the present disclosure may also have the following subsidiary configurations. <Configuration 2> In configuration 1, the attachment holes on both the left and right sides may be provided so as to be located above the center in the vertical direction from the lower edge of the armhole to the lower end of the upper garment. <Configuration 3> In configuration 1 or 2, the vertical dimension of the pleated folding portions on both the left and right sides may be four times or more the vertical dimension of the mounting holes on both the left and right sides that are positioned between the upper and lower ends of these pleated folding portions in the vertical direction. <Configuration 4> In any one of configurations 1 to 3, the pleated folding portions on both the left and right sides may be arranged so that the vertical dimension from their respective upper ends to the mounting holes is greater than the vertical dimension from their respective lower ends to the mounting holes. <Configuration 5> In any one of configurations 1 to 4, the pleated folded portions on both the left and right sides may be provided so as to cover a part of the mounting holes on both the left and right sides in a folded state. <Configuration 6> In any one of configurations 1 to 5, the back body may be provided with a pair of upper mounting holes on the left and right sides, to which the air blowers are attached, located above the mounting holes on the left and right sides and between the pleated folding portions on the left and right sides. <Configuration 7> In configuration 6, a blocking sheet may be provided to block at least two of the left and right mounting holes and the pair of left and right upper mounting holes.

[0008] In order to achieve the above-mentioned object, the upper garment with a blower according to the present disclosure is characterized by comprising an upper garment having any one of configurations 1 to 7 according to the present disclosure and a blower attached to an attachment hole of the upper garment. [Effects of the Invention]

[0009] The upper garment of the present disclosure and the upper garment equipped with the air blower that includes the same are configured as described above, thereby reducing interference between the air blower attached to the mounting hole and the back, arms, etc. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In some drawings, some of the detailed reference numerals used in other drawings are omitted. In the following embodiment, directions such as up and down directions will be described based on a wearer wearing the upper garment (upper garment with a blower) according to this embodiment in a standing position.

[0012] 1 to 5 are diagrams that schematically show an example of an upper garment according to this embodiment, an example of an upper garment equipped with a blower including the same, and a modified example of the upper garment and an example of an upper garment equipped with a blower including the same. As shown in Figures 1(b) and 3(a), the upper garment 2 according to this embodiment is configured such that mounting holes 26, 26 to which air blowers 3 that take in outside air are attached are provided in both left and right sides (lateral sides) 25, 25 of the back body 20. As shown in Figure 3, the upper garment 1 with air blowers according to this embodiment includes the upper garment 2 and air blowers 3, 3 attached to the mounting holes 26, 26 of the upper garment 2. In such an upper garment 1 with air blowers (or an upper garment 2 with air blowers 3 attached), driving the air blowers 3 allows outside air to be taken into the upper garment 1, thereby cooling the wearer's body.

[0013] As shown in Figure 2(a), the mounting holes 26, 26 on both the left and right sides are provided so that their respective hole centers 6 are located above the vertical center (lower center) 7 from the lower edge 17 of the armhole 16 of the upper garment 2 to the lower end 12 of the upper garment 2. On each of the left and right sides of the back body 20, pleated folding portions 22, 22 are provided extending in the vertical direction and are freely foldable and unfoldable, and in the unfolded state, move the mounting holes 26, 26 on both the left and right sides outward in the lateral direction (see also Figures 3 and 4). With this configuration, when the air blowers 3, 3 attached to the left and right mounting holes 26, 26, respectively, are driven, the left and right pleated folding portions 22, 22 are unfolded, and the left and right air blowers 3, 3 move outward in the lateral direction, respectively. As a result, even when the backrest 8 is close to the body when sitting in a chair or when the body is close to the ground or the like when lying on one's back, the air blowers 3, 3 are positioned closer to the side of the body, thereby reducing pressure on the back caused by the air blowers 3, 3. Furthermore, the air blowers 3, 3 attached to the left and right mounting holes 26, 26 are positioned higher and closer to the armpits, so that compared to a configuration in which the air blowers 3, 3 are positioned to the side near the waist, pressure on the back caused by the air blowers 3, 3 can be effectively reduced even when sitting in a chair with a backrest 8 that curves around the waist to surround the back side of the waist, and the air blowers 3, 3 are less likely to interfere with the fingers, arms, etc.

[0014] In this embodiment, as shown in FIGS. 1(a) and 1(b), a sleeveless (vest-type) top (upper body garment) 2 is exemplified. The top 2 may be made of any suitable material, such as soft, low-breathability (or non-breathable), cotton or polyester. The top 2 comprises a front body 10, a back body 20, and a collar 18. The front body 10 and the back body 20 are joined by stitching or the like, and the collar 18 may be joined to the front body 10 and the back body 20 by stitching or the like. Specifically, the left and right end edges of the front body 10 and the back body 20 and the left and right shoulders may be joined by stitching or the like. The left and right armholes 16, 16 are made up of armholes (front armholes and rear armholes) that form armholes provided on both the left and right sides of the front body 10 and the back body 20, respectively. The collar 18 may be joined to the upper edges of the front body 10 and the back body 20 by stitching or the like.

[0015] The lower end of the top 2 (front body section 10 and back body section 20) is provided with a hem section 13 that can fit snugly against the wearer's body or clothing, such as underwear. The hem section 13 is tubular and conforms to the lower end 12. A string-like member 14 made of a stretchable material, such as rubber, is inserted into the tubular section, leaving a portion of the string-like member 14 exposed (see FIG. 2(a)). The exposed portion of the string-like member 14 is provided with a stopper 15 that prevents the string-like member 14 from returning to its original position after being pulled out of the hem section 13. In other words, when the string-like member 14 is pulled out of the hem section 13 and the stopper 15 prevents the string-like member 14 from returning to its original position, the hem section 13 is tightened, allowing the hem section 13 to fit snugly against the wearer's body and prevent air from leaking downward. This configuration allows the degree of tightening of the hem section 13 by the string-like member 14 to be adjusted, and it is even possible to achieve a degree of tightening that allows air to leak downward. This allows air to be blown to the lower body, such as the buttocks. Instead of the above-described adjustable structure for the degree of tightening, hem 13 may be structured to include elastic material such as rubber so that hem 13 is tight. Hem 13 may be formed by the lower end portions of front body 10 and back body 20, or may be joined to the lower edges of these by stitching or the like.

[0016] The front body 10 is separated into a left front body 10A and a right front body 10B. In other words, the top 2 is an open-front type. An opening / closing section 11 for opening and closing the front of the top 2 is provided at the joining portion of the left and right front body sections 10A, 10B. The opening / closing section 11 includes a left opening / closing section 11a provided along the front opening side end, which is the butting end of the left front body section 10A, and a right opening / closing section 11b provided along the front opening side end, which is the butting end of the right front body section 10A, and may be a linear fastener that allows these sections to be connected and disconnected. The linear fasteners (slide fasteners) used as these opening / closing sections 11a, 11b may be joined to each front opening side end by stitching or the like, and may have elements (teeth) at the butting end that engage with each other, with a slider on one side for engaging and disengaging the elements. Instead of or in addition to such a linear fastener, the opening and closing sections 11a, 11b may be hook-and-loop fasteners or fasteners such as buttons. In the illustrated example, the opening and closing sections 11a, 11b are provided continuously from the joining parts of the left and right front body sections 10A, 10B to the hem section 13 and collar section 18. Appropriate pockets or the like may be provided in appropriate places on the front body section 10, etc.

[0017] As shown in Figure 2(a), the mounting holes 26, 26 on both the left and right sides are positioned above the vertical center (lower center) 7 from the lower edge 17 of the armhole 16 to the lower end 12 of the top 2. With this configuration, the air blowers 3, 3 attached to the left and right mounting holes 26, 26 are positioned higher up on the underarm side, more effectively reducing back pressure and interference with the arms, etc. The lower edge 17 of the armhole 16 is the lowest position of the hole-shaped armhole 16 and is the reference position for the body width. The lower end 12 of the top 2 is the lower end of the hem 13. The vertical direction from the lower edge 17 of the armhole 16 to the lower end 12 of the top 2 is the garment length (body length) direction, and the lower edges of the attachment holes 26, 26 are provided above the lower center 7, which is on the lower side of the top 2 in this vertical direction. In other words, the left and right attachment holes 26, 26 are provided so as to be located between the lower edge 17 of the armhole 16 and the lower center 7.

[0018] These left and right attachment holes 26, 26 are provided so as to penetrate through the lateral side regions 25, 25 on both the left and right sides of the back body 20. These attachment holes 26, 26 have a substantially perfect circular shape when viewed in the thickness direction (viewed in the penetration direction) of the back body 20. The diameter D, which is the dimension in the up-down direction, of these attachment holes 26, 26 is the same. These attachment holes 26, 26 are provided at the same height in the vertical direction and spaced apart from each other in the left-right direction. More specifically, these attachment holes 26, 26 are provided at positions that are symmetrical with respect to the center line that passes through the center of the back body 20 in the left-right direction.

[0019] The height (vertical position) at which these mounting holes 26, 26 are provided, i.e., the height at which the air blowers 3, 3 described below are attached, may be appropriately determined depending on the preference, type of work, working posture, etc. of the wearer wearing the upper garment 2 (upper garment 1 with air blowers). These mounting holes 26, 26 may be provided at approximately the same height as the wearer's elbows or above the wearer's elbows. In the illustrated example, the left and right mounting holes 26, 26 are provided at positions where the vertical dimension from the lower edge 17 of the armhole 16 to the left and right mounting holes 26, 26 is greater than the vertical dimension from these holes to the lower center 7. However, they may be provided at appropriate positions depending on the size of the upper garment 2, etc. For example, the vertical dimension from the lower edge 17 of the armhole 16 to the left and right mounting holes 26, 26 may be the same for all sizes, and the vertical dimension below the left and right mounting holes 26, 26 may be different for each size. Furthermore, the left and right dimensions of the pleated folded portions 22, 22 and the lateral side portions 25, 25 described below may be the same for all sizes, and the left and right dimensions of the left and right central portion 21 of the back body 20 may be different for each size.

[0020] Additionally, an appropriate reinforcing sheet may be provided around the attachment holes 26, 26 of the back body 20 to reinforce the peripheral edges of the attachment holes 26, 26. Such a reinforcing sheet may be in the form of a circular plate surrounding the attachment holes 26, 26, or a rectangular plate with holes corresponding to the attachment holes 26, 26. These reinforcing sheets may be made of a hard synthetic resin sheet or the like that is more rigid and less likely to deform than the fabric that constitutes the top 2 (back body 20). These reinforcing sheets may be fixed to the back surface (the surface facing the wearer, the inner surface) of the back body 20, or may be enclosed between the outer fabric and lining that constitute the back body 20. The air blowers 3, 3 attached to the respective attachment holes 26, 26 have the same configuration, so the following description will be given taking one of the air blowers 3 as an example.

[0021] As shown in Figures 3 and 4, the blower 3 is configured such that driving parts such as blades and a motor are housed in a tubular part 4 that constitutes a fan case. The blower 3 may be an axial fan. The tubular part 4 has a thin, approximately cylindrical shape. An intake port for drawing in outside air is provided on the outside, which is one axial side of the tubular part 4 (the surface side of the upper garment 2 that is the side away from the wearer), and an outlet port for blowing outside air into the upper garment 2 is provided on the inside, which is the other axial side of the tubular part 4 (the back side of the upper garment 2). The intake port and outlet port of the tubular part 4 are provided with appropriate linear or lattice-shaped guard parts.

[0022] A flange 5 that protrudes radially outward along the entire circumference is provided on the suction port side peripheral edge portion on the surface side of the cylindrical portion 4 of the blower 3. The outer diameter of this flange 5 is larger than the hole diameter D of the mounting hole 26. Although not shown, a ring-shaped member is fitted onto the cylindrical portion 4 of the blower 3. The ring-shaped member has an inner diameter that corresponds to the outer diameter of the cylindrical portion 4. The ring-shaped member and the flange portion 5 are configured to sandwich and hold the periphery of the mounting hole 26. The cylindrical portion 4 and the ring-shaped member are provided with appropriate locking portions that detachably lock them to each other. Such locking portions may be configured as a locking recess and a locking claw that detachably locks thereto, or as a female threaded portion and a male threaded portion that screws into the female threaded portion, or may have various other configurations.

[0023] The air blower 3 is provided with an appropriate connector to which one end of a power cord that supplies driving power to the air blower 3 is connected. The other end of the power cord is connected to a power supply device that constitutes a power supply unit. Such a power supply device may be configured to accommodate replaceable dry batteries or the like, or preferably to incorporate a rechargeable secondary battery (storage battery). In this case, the power supply device may be provided with an appropriate connector to be connected to a commercial power source (external power source) or the like when charging the secondary battery. The power supply device may be provided with an operation unit that is operated to turn on (start) / off (stop) the air blower 3 and an air volume adjustment operation unit that is operated to adjust (change) the air volume of the air blower 3. The power supply device may also be provided with a display unit that displays the air volume strength level and operating status of the air blower 3, an estimate of the remaining charge of the secondary battery, etc. The blower 3 is not limited to a substantially cylindrical configuration, but may be a substantially rectangular cylindrical configuration. Also, although the blower 3 has a flange 5 on the inlet side, the blower 3 may not have such a flange 5, or may have various other configurations. The top 2 may be provided at an appropriate location with a housing for housing the power supply device of the air blower 3, a holder for holding an intermediate portion of the power cord, and the like.

[0024] 1(b) and 2(a), in this embodiment, the left and right pleated folding portions 22, 22 are arranged to cover portions of the left and right mounting holes 26, 26 in the folded state. That is, the pleated folding portion 22 on one side in the left-right direction covers portions of the mounting hole 26 on one side in the left-right direction in the folded state, and the pleated folding portion 22 on the other side in the left-right direction covers portions of the mounting hole 26 on the other side in the folded state. This configuration effectively increases the lateral dimension between the left and right pleated folding portions 22, 22 of the back body piece 20, i.e., the lateral dimension of the lateral central portion 21 of the back body piece 20, making it easier to arrange various components, such as a coolant storage portion 29, in the lateral central portion of the back body piece 20. The vertical dimension (pleat length dimension) H1 of the left and right pleated folded portions 22 may be four or more times the diameter D of the left and right mounting holes 26, 26 provided to be positioned between the upper ends 22c, 22c and the lower ends 22d, 22d of these pleated folded portions 22, 22 in the vertical direction. With this configuration, the back side of the upper garment 2 is more likely to spread rearward and outward in the left and right directions compared to when the pleat length dimension H1 of the pleated folded portions 22 is approximately two to three times the diameter D of the mounting holes 26, and pressure on the back by the air blower 3 and interference with the arms, etc. can be more effectively reduced. The upper limit of the pleat length dimension H1 of the left and right pleated folded portions 22, 22 may be the same dimension as the body length of the upper garment 2 (from the shoulders to the lower end 12), or may be approximately 9 / 10 of the body length.

[0025] The left and right pleated folded portions 22 are arranged so that the vertical dimension (upper length dimension) H2 from each upper end 22c to the mounting holes 26 is greater than the vertical dimension (lower length dimension) H3 from each lower end 22d to the mounting holes 26. With this configuration, the pleated folded portions 22 are arranged to extend further upward on the sides of the air blower 3, which is arranged at a relatively upward position on the underarm side as described above, so that the upper side of the back of the upper garment 2 can easily spread rearward and outward in the left-right direction, improving air flow and appearance. In other words, for example, in a configuration in which the stretchable portion is provided only on the lower part of the clothing body and the vertical center of the stretchable portion is located lower than the center of the attachment hole, the lower side of the clothing will be wider in the rear and width directions than the upper side of the clothing, which could reduce the air flow at the upper side of the back of the clothing or make the waist area appear thicker, resulting in an unattractive appearance; however, with the above configuration, such concerns do not arise.

[0026] Specifically, the left and right pleated folded portions 22, 22 are provided so as to form boundaries between the left-right central portion 21 of the back body 20 and the left and right lateral side portions 25, 25 on both sides of this central portion 21. A storage section 29 capable of storing a cooling material or the like is provided in the central section 21 of the back body 20. This storage section 29 is provided so as to be located at the same height as the left and right mounting holes 26, 26 in the left-right central section of the central section 21. In the illustrated example, the storage section 29 is provided so that the vertical center of the storage section 29 is below the hole centers 6 of the mounting holes 26, 26, but is not limited to this example. The storage section 29 may be sewn to the central section 21 at both left and right ends and at the bottom end, and may be formed into a pocket shape that opens upward. The storage section 29 may be made of an appropriate material that is flexible and highly (good) breathable. Such a material may be, for example, a mesh fabric woven into a net shape using a tricot knitting machine or a raschel knitting machine. The cooling material stored in the storage section 29 may be a moisture-impregnated cloth or sheet, or may be a moisture-retaining pad, a moisture-retaining sheet, an ice pack, or the like. Note that the storage section 29 may not be provided.

[0027] The left and right pleated folds 22, 22 are arranged so that their longitudinal direction is the same as the length direction of the garment, but they may be inclined at an angle of about 20 degrees or less with respect to the length direction. For example, the left and right pleated folds 22, 22 may be formed so that they approach or move away from each other from the upper ends 22c, 22c to the lower ends 22d, 22d. These left and right pleated folded portions 22, 22 are provided at positions that are symmetrical with respect to a center line that passes through the center of the back body 20 in the left-right direction. Because these left and right pleated folded portions 22, 22 are symmetrical, one of them will be described below as an example. Note that Figures 2(b) and 2(c) show schematic cross-sectional views to explain an example of the configuration of the pleated folded portion 22, and the thickness, width, layer structure, etc. are not limited to those shown in the figures.

[0028] 2(b), the pleated folded portion 22 includes a front-side region 23 connected to an end of the central portion 21, and a back-side region 24 connected to the front-side region 23 via a first bent portion 22a and overlapping the back side of the front-side region 23 in the folded state. That is, the pleated folded portion 22 is folded in a mountain fold on the front side of the upper garment 2, with the front-side region 23 and the back-side region 24, with the first bent portion 22a as the apex. The back-side region 24 is provided so as to be connected to a central end of the side-side region 25 via a second bent portion 22b in the folded state. In other words, the pleated folded portion 22 is folded in a mountain fold on the back side of the upper garment 2, with the central end of the side-side region 25 and the back-side region 24, with the second bent portion 22b as the apex. In the illustrated example, the first bent portion 22a and the second bent portion 22b are edge-stitched. The central portion 21 and the lateral side portions 25 of the back body 20, including the pleated folded portion 22, may be formed from a single piece of fabric material, and one or both of the first bent portion 22a and the second bent portion 22b may be sewn together.

[0029] The folded width W of this pleated folded portion 22 (the dimension from the seam of the first bent portion 22a to the seam of the second bent portion 22b in the folded state) may be, for example, about 30 mm to 80 mm, or may be 60 mm or less. 2(c), when the pleated folded portions 22 are unfolded, the central portion 21 and the lateral side portions 25 are spaced apart from each other by the front side portion 23 and the back side portion 24, compared to when they are in the folded state. In other words, when the pleated folded portions 22 are unfolded, the central portion 21 and the lateral side portions 25 are spaced apart by a distance equal to twice the folding width W, which corresponds to the width of each of the front side portion 23 and the back side portion 24.

[0030] The upper ends 22c of the pleated folded portions 22 are located at the shoulders. The upper ends 22c of the pleated folded portions 22 may be sewn to the seam between the upper ends of the front body 10 and the back body 20, or may be sewn to an appropriate shoulder yoke or the like provided at the shoulders. In the illustrated example, the upper end reference position of the pleat length dimension H1 and the upper length dimension H2 is the upper end of the first bent portion 22a of the pleated folded portion 22. Instead of positioning the upper ends 22c of the pleated folded portions 22 at the shoulders, they may be located lower than in the illustrated example. For example, the upper ends 22c of the pleated folded portions 22 may be located at a height approximately equal to the center of the armholes 16 in the vertical direction. In this case, the first bent portion 22a side portion above the upper end 22c may be sewn to the lateral side portion 25 to prevent unfolding, similar to the lower end 22d side described below.

[0031] The lower end 22d of the pleated folded portion 22 is located above the lower end 12 of the upper garment 2. The lower end 22d of the pleated folded portion 22 is located above the hem portion 13. A region on the first bent portion 22a side below the lower end 22d of the pleated folded portion 22 is formed as a lower end seam 22e sewn to the lateral side region 25. In other words, the lower end seam 22e is sewn to the lateral side region 25 and is therefore unable to unfold. The lower end 22d is also formed by sewing the area between the upper end of the lower end seam 22e and the second bent portion 22b to the lateral side region 25. With this configuration, when the lower end sewn portion 22e is provided, the lower end side of the pleated folded portion 22 does not look like a hole (a cylinder) compared to a configuration in which the lower end 22d is not sewn, and in other words, the sewn portion of the lower end 22d becomes the bottom, improving the appearance. Furthermore, the lower end 22d is sewn obliquely so as to become upward as it goes from the upper end of the lower end sewn portion 22e toward the second bent portion 22b. With this configuration, for example, compared to a configuration in which the lower end 22d is sewn horizontally, the pleated folded portion 22 spreads more easily when unfolded, that is, the lower end 22d, which becomes the bottom, is more easily exposed, improving the appearance.

[0032] The lower end 22d of the pleated folded portion 22 may be of an appropriate height so that the air blower 3 above it can easily move sideways when the pleated folded portion 22 is unfolded. The lower length dimension H3 from the lower end 22d of the pleated folded portion 22 to the mounting hole 26 may be approximately 30 mm to 200 mm, or may be approximately 40 mm to 150 mm. In the illustrated example, the upper end of the lower end 22d, which is sewn diagonally as described above, is used as the lower-end reference position for the pleat length dimension H1 and the lower length dimension H3. The lower length dimension H3 may be about 1 / 10 to 9 / 10 of the upper length dimension H2, depending on the size of the top garment 2 and the like. The lateral position of the pleated folded portion 22 may be located approximately in the lateral center of the shoulder portion, depending on the folding width W. The lateral dimension of the portion of the pleated folded portion 22 that covers part of the mounting hole 26 in the folded state may be, for example, approximately 1 / 5 to 4 / 5 of the hole diameter D, depending on the folding width W and the diameter D of the mounting hole 26. The pleated folded portion 22 is not limited to being folded once as in the illustrated example, but may be folded multiple times.

[0033] When using the upper garment 2 (the upper garment 1 with the air blower 3) having the above-described configuration, the upper garment 2 may be worn and the air blower 3 may be driven with the opening / closing section 11 closed over substantially the entire length, as shown in FIG. 1(a). This allows outside air to be drawn into the upper garment 2 through the air blower 3's inlet, suppressing air leakage from the front opening and the hem 13, and unfolding the left and right pleated folded sections 22, 22, as shown in FIGS. 3(b) and 4. This moves the left and right air blowers 3, 3 from the back to the left and right sides, reducing interference with the chair backrest 8, arms, etc. This also creates an air circulation space between the wearer and the inner surface of the upper garment 2, allowing the wearer to be cooled. The air drawn into the upper garment 2 is exhausted from exhaust sections, such as between the collar 18 and the neck and at the armholes 16, 16.

[0034] Next, a modified example of the jacket and the jacket with the air blower including the same will be described with reference to FIG. In the following modified examples, differences from the previously described example will be mainly described, and explanations of similar configurations will be omitted or briefly explained. In addition, in the following modified examples, explanations of the same operational effects as those of the previously described example will be omitted or briefly explained.

[0035] 5(a) and (b) schematically show an example of an upper garment 2A according to a first modified example and an upper garment 1A with a blower provided therewith. In this modification, the back body 20A is provided with a pair of upper mounting holes 27, 27 to which the air blowers 3 are attached, located above the mounting holes 26, 26 on both the left and right sides and between the pleated folded portions 22, 22 on both the left and right sides. With this configuration, the air blowers 3 can be attached to both the upper mounting hole 27 and the lower mounting hole 26, and the wearer's body can be cooled more effectively.

[0036] The upper garment 2A includes blocking sheets 28 that block at least two of the left and right mounting holes 26 and the pair of left and right upper mounting holes 27. With this configuration, two of the upper mounting holes 27 and the lower mounting holes 26 can be blocked with the blocking sheets 28, and air blowers 3 can be attached to the remaining two. This allows the air blowers 3 to be attached to the mounting holes 26 at appropriate positions depending on the wearer's preferences and the type of work to be performed while wearing the garment. For example, as shown in FIG. 5(b), it is also possible to attach the air blower 3 to the upper mounting hole 27 on one side of the left and right upper mounting holes 27, block the upper mounting hole 27 on the other side with the blocking sheet 28, and block the mounting hole 26 on one side of the left and right lower mounting holes 26 with the blocking sheet 28, and attach the air blower 3 to the mounting hole 26 on the other side. In other words, the two air blowers 3, 3 are arranged asymmetrically, i.e., diagonally, on the upper and lower sides, which makes it possible to suppress interference between the belt 9 and the air blowers 3, 3 when, for example, the belt 9 of various work machines or bags is worn diagonally.

[0037] Specifically, as shown in Figure 5(a), the left and right upper attachment holes 27, 27 are provided on both the left and right sides of the central portion 21A of the back body 20A. These upper attachment holes 27, 27 are provided so as to penetrate the central portion 21A, similar to the above-mentioned attachment hole 26. These upper attachment holes 27, 27 have a substantially perfect circular shape when viewed in the thickness direction of the back body 20A (viewed in the penetration direction). The hole diameters of these upper attachment holes 27, 27 are the same as each other and are also the same diameter as the hole diameter D of the above-mentioned attachment hole 26. These upper-stage attachment holes 27 are provided at the same height in the vertical direction and spaced apart from each other in the left-right direction. More specifically, these upper-stage attachment holes 27 are provided at positions that are symmetrical about a center line that passes through the center of the back body 20A in the left-right direction.

[0038] In the illustrated example, these upper mounting holes 27, 27 are provided so that their respective hole centers are at approximately the same height as the lower edge of the armhole 16. These upper mounting holes 27, 27 may also be provided so that their respective hole centers are at approximately the same height as the lower edge of the armhole 16 or higher than the lower edge of the armhole 16. Furthermore, these upper-stage mounting holes 27, 27 are provided so that a portion of each reaches a portion of the surface-side portions 23, 23 of the left and right pleated folded portions 22, 22. These upper mounting holes 27, 27 are provided so that their respective hole centers are positioned closer to the center in the left-right direction than the hole centers of the left and right mounting holes, 26, 26. The positions at which the upper mounting holes 27, 27 are provided are not limited to the positions shown in the illustration, and other positions may also be used.

[0039] As shown in Figure 5(b), the blocking sheet 28 is larger than the hole diameter D of the mounting hole 26 and the upper mounting hole 27 so that it can cover these holes. In the example shown, the blocking sheet 28 is rectangular when viewed in the thickness direction, but it may also be circular or the like. The closure sheet 28 may be held in an appropriate sheet storage section or the like provided on the back (inner) side of the back piece 20A, or may be held on the inner side of the back piece 20A by a hook-and-loop fastener or the like. The mounting holes 26 and upper mounting holes 27 that are blocked by the blocking sheets 28 are not limited to the example shown in Fig. 5(b). For example, the left and right upper mounting holes 27 may be blocked by blocking sheets 28, and the air blowers 3 may be attached to the left and right lower mounting holes 26, or conversely, the left and right lower mounting holes 26 may be blocked by blocking sheets 28, and the air blowers 3 may be attached to the left and right upper mounting holes 27. Furthermore, without providing such blocking sheets 28, 28, the air blowers 3, 3, 3, 3 may be attached to the left and right mounting holes 26, 26 on the lower stage side and the left and right mounting holes 27, 27 on the upper stage side, respectively.

[0040] Furthermore, appropriate spacers or the like for ensuring air circulation space may be provided at appropriate locations on the inner surface of the upper garments 2, 2A in each of the above examples. Furthermore, the positions of the left and right mounting holes 26, 26 on the lower side in each of the above examples, the left and right positions of the pleated folding portions 22, 22, the folding width W, the pleat length dimension H1, the upper length dimension H2, the lower length dimension H3, etc. are not limited to the above examples and may be configured in various other ways. In the above examples, sleeveless (vest-type) tops 2, 2A are illustrated, but tops with short or long sleeves may also be used. In other words, the sleeves may be joined to the armholes 16 of the tops 2, 2A. The specific configurations of the members and parts of the upper garments 2, 2A and the upper garments 1, 1A with air blowers that include the upper garments 2, 2A according to the above-described embodiments are merely examples, and various other modifications are possible.
