[0004] However, in the air-conditioned clothing described in Patent Document 1, hook-and-loop fasteners and mesh pockets are provided in the center of the back side of the back body, extending vertically, and there is a concern that the seams joining these to the back body may be easily noticeable on the front side of the back body.

[0005] The present disclosure has been made in consideration of the above-mentioned situation, and aims to provide an upper garment that can improve the appearance of the front side of the back while ensuring air circulation space on the back side, and an upper garment equipped with an air blower that includes the same. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, configuration 1 of the upper garment disclosed herein is an upper garment to which a blower that takes in outside air is attached, and is characterized in that both ends are joined to both ends on the inner side of the back of the upper garment, and the upper garment has a sheet-like portion that is spanned between both ends on the inner side of the back, and the sheet-like portion is provided with a holding portion that holds a spacer that ensures air circulation space.

[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, both ends of the sheet-like portion may be joined to both armhole portions that constitute both ends of the back body. <Configuration 3> In configuration 2, both ends of the sheet-like portion may be joined to both shoulder portions constituting both ends of the back body in addition to the armhole portions on both sides. <Configuration 4> In any one of configurations 1 to 3, the sheet-like portion may be provided so that the upper edge between both ends thereof is aligned with the upper edge of the back body. <Configuration 5> In configuration 4, the upper edge of the sheet-like portion may be joined to the upper edge of the back body. <Configuration 6> In any one of configurations 1 to 5, the sheet-like portion may be provided with a pair of holding portions spaced apart in the left-right direction, each holding the spacer, which is arranged so that the longitudinal direction is the up-down direction, so that an air circulation space is formed at the center of the left-right direction of the back body. <Configuration 7> In configuration 6, a housing portion for housing a cooling member may be provided between the pair of holding portions in the sheet-like portion.

[0008] In order to achieve the above object, the upper garment with a blower according to the present disclosure is characterized by comprising the upper garment 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 disclosed herein and the upper garment equipped with a blower having the same are configured as described above, thereby enabling air circulation space to be secured on the back side while improving the appearance of the front side of the back body.

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

[0012] 1 to 4 are diagrams schematically showing an example of an upper garment according to the first embodiment and an example of an upper garment equipped with the same and equipped with a blower. As shown in Figures 1 and 3, the upper garment 2 according to this embodiment is an upper garment to which a blower 3 that takes in outside air is attached. The upper garment 1 with a blower according to this embodiment includes the upper garment 2 and the blower 3 that is attached to a mounting hole 13 of the upper garment 2. In such an upper garment 1 with a blower (or an upper garment 2 with the blower 3 attached), driving the blower 3 allows outside air to be taken into the upper garment 1 with a blower, thereby cooling the wearer's body.

[0013] The upper garment 2 has both ends (25, 26) joined to both ends (15, 16) on the inner side of the back body 12 of the upper garment 2, and is equipped with a sheet-like portion 20 that spans between the both ends (15, 16) on the inner side of the back body 12 of the upper garment 2. The sheet-like portion 20 is provided with a retaining portion 21 that retains a spacer 6 that ensures air circulation. With this configuration, by retaining the spacer 6 in the retaining portion 21 of the sheet-like portion 20, an air circulation space can be ensured by the spacer 6 between the back side of the wearer or underwear, etc. and the back body 12 of the upper garment 2. This facilitates air circulation on the back side even when the wearer's back is bent or a belt, baggage, etc. is hung on the back side, thereby improving the cooling effect. Furthermore, since the sheet-like portion 20 that holds the spacer 6 is bridged between both ends (15, 16) on the inner side of the back body 12, no seams or other joining portions between the both ends (25, 26) of the sheet-like portion 20 and the back body 12 are formed in the central portion on the front side of the back body 12, improving the appearance. This also makes it possible to apply embroidery, printing, etc. to the central portion on the front side of the back body 12. An example of a specific configuration of the sheet-like portion 20 and the spacer 6 held therein will be described later.

[0014] In this embodiment, a long-sleeved 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. This jacket 2 comprises a front body 10, a back body 12, left and right sleeves 17, 17, and a collar 19. The front body 10 and the back body 12 may be joined by stitching or the like, and the left and right sleeves 17, 17 and the collar 19 may be joined to the front body 10 and the back body 12 by stitching or the like. Specifically, the left and right end edges of the front body 10 and the back body 12 and the left and right shoulders (15) may be joined to each other by stitching or the like. The left and right sleeves 17, 17 may be joined to armholes (front armholes 11, 11 and rear armholes 16, 16) 11, 11, 16, 16 that form armholes provided on the left and right sides of the front body 10 and the back body 12, respectively, by stitching or the like. The collar 19 may be joined to the upper edges (14) of the front body 10 and the back body 12 by stitching or the like.

[0015] The lower end of the top 2 (front body 10 and back body 12) is provided with a hem 18 configured to fit snugly against the wearer's body or clothing such as underwear. This hem 18 constitutes a drawstring that prevents air from leaking downward. Such hem 18 may be configured to contain elastic material such as rubber. This hem 18 may be joined to the lower edges of the front body 10 and back body 12 by stitching or the like. Hem 18, which constitutes a drawstring, may be configured such that a string-like member made of elastic material such as rubber is inserted into a tube so that a portion of it is exposed, allowing the degree of drawstring to be adjusted. 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. At the joining portion of the left and right front body parts 10A, 10B, opening and closing sections 10a, 10b are provided for opening and closing the front of the top 2. These opening and closing sections 10a, 10b may be interlocking linear fasteners (slide fasteners) or hook-and-loop fasteners, or may be buttons, or a combination of these. In the illustrated example, the opening and closing sections 10a, 10b are provided continuously from the joining portion of the left and right front body parts 10A, 10B to the hem 18 and collar 19.

[0016] As shown in Figures 1 and 2, the attachment holes 13 of the top 2 are provided in the back body 12. More specifically, two attachment holes 13, 13 are provided in the back body 12. These attachment holes 13, 13 are provided so as to penetrate through the back body 12. In the illustrated example, these attachment holes 13, 13 are substantially circular when viewed in the thickness direction of the back body 12 (viewed in the penetration direction). These attachment holes 13, 13 have the same diameter. These mounting holes 13 are provided at the same height in the vertical direction and spaced apart from each other in the left-right direction. More specifically, these mounting holes 13 are provided at positions symmetrical with respect to the center line passing through the center of the back body 12 in the left-right direction.

[0017] The height positions (vertical positions) at which these mounting holes 13, 13 are provided, i.e., the height positions at which the air blowers 3, 3 described below are attached, may be set appropriately depending on the preferences, type of work, working posture, etc. of the wearer of the upper garment 2 (upper garment 1 with air blowers). In the illustrated example, these mounting holes 13, 13 are shown provided at height positions close to the waist, which is the lower part of the back body 12 in the vertical direction. Instead of such positions, these mounting holes 13, 13 may be provided at the center or upper part of the back body 12 in the vertical direction. Appropriate reinforcing sheets may be provided around the attachment holes 13, 13 of the upper garment 2 (back body 12) to reinforce the periphery of the attachment holes 13, 13. Such reinforcing sheets may be in the form of circular plates surrounding the attachment holes 13, 13, or in the form of rectangular plates with holes corresponding to the attachment holes 13, 13. 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 upper garment 2 (back body 12). These reinforcing sheets may be fixed to the back surface (the surface facing the wearer, the inner surface) of the back body 12, or may be enclosed between the outer fabric and lining that constitute the back body 12.

[0018] The air blowers 3, 3 attached to the respective attachment holes 13, 13 have the same configuration, so the following description will be given taking one of the air blowers 3 as an example. The blower 3 is configured such that driving parts such as blades and a motor are housed within a tubular portion 4 that constitutes a fan case. The blower 3 may be an axial fan. The tubular portion 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 portion 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 portion 4 (the back side of the upper garment 2). The intake port and outlet port of the tubular portion 4 are provided with appropriate linear or lattice-shaped guard portions.

[0019] 1 and 3, a flange 5 that protrudes radially outward along the entire circumference is provided on the suction port side peripheral edge of the cylindrical portion 4 of the blower 3. The outer diameter of the flange 5 is larger than the inner diameter of the mounting hole 13. 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 13. 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.

[0020] 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 top 2 may be provided at an appropriate location with a housing for housing the power supply device, a holder for holding an intermediate portion of the power cord, and the like.

[0021] As shown in Figures 1 and 2(b), both ends (25, 26) of the sheet-like portion 20 are joined to the armholes 16, 16 on both sides that constitute both ends of the back body 12. In other words, the armhole joining portions 26, 26 that constitute both ends of the sheet-like portion 20 are joined to the armholes 16, 16 that constitute the rear armholes on both sides that are on the back body 12 side of the armholes (armholes) of the upper garment 2. With this configuration, the sheet-like portion 20 is provided at a relatively high position on the back body 12, closer to the collar 19, and the spacer 6 ensures an air circulation space between the high position on the back and the back body 12 of the upper garment 2. This allows air to be directed effectively toward the neck area, where the cooling effect is greatest, thereby improving the cooling effect. Both ends (25, 26) of the sheet-like portion 20 are joined to the armholes 16, 16 on both sides, as well as to the shoulders 15, 15 on both sides that constitute both ends of the back body 12. In other words, the shoulder joining portions 25, 25 that constitute both ends of the sheet-like portion 20 are joined to the shoulders 15, 15 on both sides that are on the back body 12 side of the shoulders of the top 2. With this configuration, the sheet-like portion 20 is provided at a higher position on the back body 20, closer to the collar 19, and air can be directed more effectively toward the neck.

[0022] The sheet-like portion 20 is arranged so that its upper edge 24 between its two ends (25, 26) is aligned with the upper edge 14 of the back body 12. In other words, the upper edge 24 between the two ends (25, 26) of the sheet-like portion 20 is aligned with the upper edge 14 of the back body 12 of the top 2, which is aligned with the joint between the back body 12 and the collar 19. This configuration allows the sheet-like portion 20 to be positioned higher on the back body 12, closer to the collar 19, and more effectively directs air toward the neck. Furthermore, the back body 12 is less likely to be exposed between the sheet-like portion 20 and the collar 19, which reduces discomfort and improves appearance. Furthermore, when a label 27 such as a logo or a tag 28 such as a size is attached to the sheet-like portion 20, it can be attached at a typical height. In the illustrated example, a rectangular label 27 is attached to the upper end portion of the center of the left-right direction of the sheet-like portion 20 by sewing or the like, and a tag 28 is attached to the lower end of this label 27, but this example is not limited to this.

[0023] The sheet-like portion 20 is provided with a pair of holding portions 21, 21 spaced apart in the left-right direction, each holding a spacer 6 that is arranged with its longitudinal direction aligned with the up-down direction, so as to form an air circulation space at the left-right center of the back body 12. With this configuration, the spacers 6, 6 held by each of the pair of holding portions 21, 21 ensure an air circulation space at the left-right center of the back body 12. Furthermore, compared to a configuration in which the spacers are provided at the left-right center, the spacers 6, 6 are less likely to come into contact with the spine, improving comfort. A storage section 22 for storing the cooling member 7 is provided between the pair of holding sections 21, 21 in the sheet-like section 20. With this configuration, the cooling member 7 is positioned in the air circulation space formed between the pair of spacers 6, 6, and the air passing through the central back portion and the circulation space can be cooled by the cooling member 7, thereby improving the cooling effect.

[0024] Specifically, the sheet-like portion 20 has a larger dimension in the left-right direction than in the up-down direction, that is, the sheet-like portion 20 is elongated in the left-right direction. The dimension of this sheet-like portion 20 along the left-right direction may be a dimension corresponding to the dimension between the armhole portions 16, 16 on both sides of the back body 12 so that the armhole joint portions 26, 26 on both sides of the back body 12 can be joined to the armhole portions 16, 16 on both sides of the back body 12. The vertical dimension of the sheet-like portion 20 may be any appropriate dimension so long as it can hold the spacer 6 arranged with its longitudinal direction aligned vertically. In the illustrated example, the dimension is such that the lower edge 23 of the sheet-like portion 20 is at approximately the same height as the lower ends of the armhole joints 26, 26 on both sides that are joined to the upper approximately half portions of the armholes 16, 16 on both sides of the back body 12. In other words, the vertical dimension of the sheet-like portion 20 corresponds to the distance from the upper edge 14 and shoulder portions 15, 15 of the back body 12 to the lower ends of the upper approximately half portions of the armholes 16, 16 on both sides. The vertical dimension of the sheet-like portion 20 is not limited to this dimension and may be smaller or larger than that shown in the illustration. In addition, the example shown in the figure shows an example in which the lower edge 23 of the sheet-like portion 20 is a straight line parallel to the lower end of the back body 12, but for example, the central portion in the left-right direction may be shaped to protrude downward or to have a concave shape.

[0025] 2(a) and 2(b), the sheet-like portion 20 has a shape that generally corresponds to the upper end portion of the back body 12 when viewed in the front-to-back direction (thickness direction). Specifically, the sheet-like portion 20 has a shape that generally corresponds to the shape of the upper end portion of the back body 12 above the lower half of the left and right armholes 16, 16 when viewed in the front-to-back direction. In other words, the upper edge 24 of the sheet-like portion 20 is located so as to generally coincide with the upper edge 14 of the back body 12, which is the joint portion with the collar 19, when viewed in the front-to-back direction. The shoulder joint portions 25, 25 on both sides of the sheet-like portion 20 are located so as to generally coincide with the shoulder portions 15, 15 on both sides of the back body 12 when viewed in the front-to-back direction. These shoulder joints 25, 25 may be joined to the shoulders 15, 15 of the back body 12 by sewing or the like, or may be joined to the shoulders of the front body 10 instead of or in addition to the shoulders 15, 15 of the back body 12. The armhole joints 26, 26 on both sides of the sheet-like portion 20 are provided so as to coincide with approximately the upper half of the armholes 16, 16 on both sides of the back body 12 when viewed in the front-to-back direction. These armhole joints 26, 26 may be joined to approximately the upper half of the armholes 16, 16 of the back body 12 by sewing or the like, or may be joined to the sleeves 17, 17 instead of or in addition to the armholes 16, 16 of the back body 12. Both ends of the sheet-like portion 20 (shoulder joints 25, 25 and armhole joints 26, 26) may be joined to the object to be joined by welding or the like instead of sewing, or may be joined in a detachable or non-detachable manner using appropriate fasteners or the like.

[0026] The upper edge 24 and the lower edge 23 of the sheet-like portion 20 are not joined to the back body 12. In other words, while the shoulder joining portions 25, 25 and the armhole joining portions 26, 26 that constitute both ends of the sheet-like portion 20 are joined to the back body 12, the upper edge 24 and the lower edge 23 are not sewn or otherwise attached to the back body 12 (top 2), and are free to come into contact with and separate from the back body 12 (top 2) (free state). 4(a) and 4(b), the holding portions 21, 21 are each formed in a pocket shape to accommodate the spacers 6, 6. With this configuration, the spacer 6 can be held more stably than with a configuration in which the spacer 6 is held at multiple points in the longitudinal direction by a belt-like member or a configuration in which the spacer 6 is held by a hook-and-loop fastener or the like. These holding portions 21, 21 have a bottom at the lower end and are formed into a vertically long cylindrical shape with an open upper end, and are configured to hold the spacers 6, 6 in a freely insertable and detachable manner.

[0027] These holding portions 21, 21 are provided so as to be located closer to the center in the left-right direction of the sheet-like portion 20 than the shoulder joint portions 25, 25 on both sides. With this configuration, the spacers 6, 6 held by these are located closer to the center in the left-right direction than the shoulder portions, and a circulation space for circulating air toward the neck side can be effectively secured between them. The left-right dimension between these holding portions 21, 21 may be an appropriate dimension so that the spacers 6, 6 held by them are less likely to interfere with the spine and so that the spacers 6, 6 can ensure space for air to circulate toward the neck, and may be, for example, approximately 100 mm to 300 mm, or approximately 150 mm to 250 mm. These holding portions 21, 21 are provided so that their upper ends are located at the upper edge 24 of the sheet-like portion 20 and their lower ends are located at the lower edge 23 of the sheet-like portion 20. Instead of this configuration, both or one of the upper and lower end portions of the holding portions 21, 21 may protrude outward in the vertical direction beyond the upper and lower edges of the sheet-like portion 20. The vertical dimension of these holding portions 21, 21 may be an appropriate dimension so that the spacers 6, 6 held by them can ensure the above-mentioned air circulation space and so that discomfort is unlikely to occur, and may be, for example, approximately 50 mm to 250 mm, or approximately 100 mm to 200 mm.

[0028] These holding portions 21, 21 may be formed by forming a tubular portion in the left-right direction of the fabric itself that constitutes the sheet-like portion 20, or by joining a tubular portion that defines the holding portions 21, 21 by sewing or the like to one thickness-wise surface of the sheet-like portion 20. Alternatively, the sheet-like portion 20 may have a multi-layer (e.g., two-layer) sheet structure in which sheets are stacked in the thickness direction, and the holding portions 21, 21 may be defined and formed by joining the sheets on both sides in the thickness direction by sewing or the like. In the illustrated example, an example is shown in which a tubular portion that defines the holding portions 21, 21 is joined by sewing or the like to the surface of the sheet-like portion 20 that faces the inner surface of the back body 12 in the thickness direction, but the present invention is not limited to this embodiment.

[0029] The spacers 6, 6 held by the holding portions 21, 21 are tubular and elongated in the vertical direction. These spacers 6, 6 are cylindrical (cylindrical) with a hollow portion penetrating in the longitudinal direction. These spacers 6, 6 are formed from a relatively flexible and cushioned material so that they can deform in response to the wearer's movements and are less likely to cause discomfort. By making the spacers 6, 6 cylindrical (cylindrical) with a hollow portion penetrating in the longitudinal direction as described above, they are moderately easily crushed and less likely to cause discomfort. Furthermore, these spacers 6, 6 may be formed from a non-breathable material that prevents air from passing across them. With this configuration, these spacers 6, 6 facilitate the formation of an air flow from the lower side to the upper side, and a rectifying effect can be expected. These spacers 6, 6 may be made of a foamed resin material such as foamed polyethylene.

[0030] The vertical dimension of these spacers 6 may be approximately the same as the vertical dimension of the holding portions 21, or may be smaller or larger than the vertical dimension of the holding portions 21. The outer diameter of these spacers 6, 6 may be set to an appropriate size so as to ensure the air circulation space as described above and to prevent discomfort, for example, it may be approximately 15 mm to 40 mm, or approximately 20 mm to 30 mm. The inner diameter of these spacers 6, 6 may be set to an appropriate size depending on the outer diameter described above and to facilitate appropriate deformation, and may be, for example, about 5 mm to 30 mm, or about 10 mm to 20 mm. The thickness (diametric dimension) of the cylindrical walls of these spacers 6, 6 may be an appropriate dimension that allows for the air circulation space as described above and that allows for moderate deformation so as to prevent discomfort, and may be, for example, approximately 5 mm to 20 mm.

[0031] 4(a) and 4(c), the storage section 22 is located between the holding sections 21, 21 on both sides and is pocket-shaped to accommodate the cooling member 7 in a removable (attachable) manner. The storage section 22 is provided so as to overlap the upper edge 24 in the left-right direction of the sheet-like portion 20. In other words, the storage section 22 is provided in a portion of the sheet-like portion 20 that is not joined to the back body 12 and is toward the center in the left-right direction. With this configuration, compared to a configuration in which a storage section for accommodating a cooling member is provided on the inner surface of the back body 12, for example, the cooling member 7 stored in the storage section 22 of the sheet-like portion 20 can be brought closer to the wearer, and air can more easily pass through both sides in the thickness direction of the cooling member 7, improving the cooling effect.

[0032] The storage section 22 has a flat bag shape with a bottom at the lower end and an open upper end. The storage section 22 may be configured by joining a bag-shaped portion that defines the storage section 22 to one thickness-wise surface of the sheet-like portion 20 by sewing or the like. Alternatively, the sheet-like portion 20 may have a multi-layer (e.g., two-layer) sheet structure in which layers are stacked in the thickness direction, and the sheets on both sides in the thickness direction are joined by sewing or the like to define the storage section 21. In the illustrated example, a sheet material that defines the storage section 22 together with the sheet-like portion 20 is joined by sewing or the like to the surface of the sheet-like portion 20 facing the inner surface of the back body 12 in the thickness direction, but the configuration is not limited to this. The cooling member 7 housed in the housing portion 22 may be a wet cloth or sheet, or may be a water-retaining pad, a water-retaining sheet, or an ice pack. The cooling unit 30 described in a second embodiment below may also be the cooling member housed in the housing portion 22. Note that the housing portion 22 for the cooling member 7 may not be provided.

[0033] The sheet-like portion 20 described above includes the holding portions 21 and the storage portion 22, and 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, a raschel knitting machine, or the like. The sheet-like portion 20 is not limited to a mesh fabric, and may be made of other breathable fabrics. When using the upper garment 2 (upper garment 1 with air blower) equipped with the air blower 3 configured as described above, the upper garment 2 is put on, the front openings 10a, 10b are closed, and the air blower 3 is driven. This allows outside air to be drawn into the upper garment 2 through the inlet of the air blower 3, creating an air circulation space between the wearer and the inner surface of the upper garment 2, thereby cooling the wearer. In addition, air circulation spaces are formed on both sides of the spacers 6, 6 held by the holding portions 21, 21, making it easier to maintain an air circulation space even when the wearer bends their back. The air drawn into the upper garment 2 is then exhausted from exhaust ports such as between the collar 19 and the neck and at the cuffs of the sleeves 17, 17.

[0034] Next, other embodiments of the upper garment and the upper garment with a blower including the upper garment will be described with reference to FIGS. In the following embodiments, differences from the previously described example will be mainly described, and the same components will be assigned the same reference numerals and their description will be omitted or simplified. In the following embodiments, the description of the same effects as those in the previously described example will also be omitted or simplified.

[0035] 5 to 7 are diagrams schematically showing an example of an upper garment according to the second embodiment and an example of an upper garment equipped with the same and equipped with a blower. In this embodiment, the main difference from the above-described example is the configuration of the mounting hole 13A of the air blower 3 and the sheet-shaped portion 20A. 5 and 6(b), the present embodiment shows an example in which two mounting holes 13A, 13A are provided in the back body 12 so as to be located above the center in the vertical direction. With this configuration, the air blowers 3, 3 attached to these mounting holes 13A, 13A are located relatively higher, and compared to a configuration in which the air blowers 3, 3 are located near the waist, it is possible to reduce pressure on the back from the air blowers 3, 3 even when sitting in a chair with a low backrest, for example. As described above, these mounting holes 13A, 13A are provided in positions that are symmetrical with respect to the center line passing through the center of the back body 12 in the horizontal direction.

[0036] The sheet-like portion 20A has its upper edge 24 joined to the upper edge 14 of the back body 12. With this configuration, compared to the configuration in which the upper edge 24 is not joined as described above, the holding portion 21A that holds the spacer 6 is less likely to shift position at the neck side, and the spacer 6 can be held stably. Furthermore, even when a storage portion 22A that stores the cooling member 7 is provided, sagging of the central portion of the sheet-like portion 20A due to the weight of the cooling member 7 can be reduced. In other words, in the present disclosure, the sheet-like portions 20, 20A only need to be unjoined to the central portion of the back body 12, and may be joined to the upper edge 14, shoulder portions 15, armhole portions 16, etc., which form the edges of the back body 12. Furthermore, for example, if the upper edge 24 of the sheet-like portion 20, 20A is located lower than the upper edge 14 of the back body 12, the upper edge 24 of the sheet-like portion 20, 20A may be reinforced by connecting it to the upper edge 14 of the back body 12 or the collar portion 19 with an appropriate string-like member or the like.

[0037] The upper edge 24 of this sheet-like portion 20A may be joined to the upper edge 14 of the back body 12 by sewing or the like, or may be joined to the collar 19 instead of or in addition to the upper edge 14 of the back body 12. The upper edge 24 of the sheet-like portion 20A may be joined to the joining object by welding or the like instead of sewing, or may be joined detachably or non-detachably by an appropriate fastener or the like. The pair of holding portions 21A, 21A provided on this sheet-like portion 20A may be provided in the same manner as in the above-mentioned example, but the illustrated example shows an example in which tubular portions constituting the holding portions 21A, 21A are joined by sewing or the like to the surface of the sheet-like portion 20A facing the wearer in the thickness direction (see FIG. 6(a)). Similarly, the storage portion 22A may be provided in the same manner as in the above-mentioned example, but the illustrated example shows an example in which a sheet material that defines the storage portion 22A together with the sheet-like portion 20A is joined by sewing or the like to the surface of the sheet-like portion 20A facing the wearer in the thickness direction.

[0038] In this embodiment, an example is shown in which a cooling unit 30 including a Peltier element or the like is detachably attached to the sheet-like portion 20A. With such a configuration, the wearer can be cooled by the cooling unit 30 in addition to the air blown by the air blower 3. Such a cooling unit 30 may be configured to incorporate an appropriate thin fan or the like on the heat dissipation side of the Peltier element. In addition, an appropriate power supply device may be provided to supply drive power to this cooling unit 30, and the power supply device of the air blower 3 may also be used as the power supply device for the cooling unit 30. Furthermore, such a cooling unit 30 may be housed in the housing 22A as the cooling member 7, but from the viewpoint of stability, it may also be fixedly attached to the sheet-like portion 20A so that the heat absorption side faces the wearer. FIG. 6(b) shows an example in which two cooling units 30, 30 are attached to the sheet-like portion 20A. Also shown is an example in which these two cooling units 30, 30 are provided on the outer side in the left-right direction than the pair of holding portions 21A, 21A. The locations and number of the cooling units 30 are not limited to those shown in the figure, and for example, a configuration in which one cooling unit 30 is provided between the pair of holding portions 21A, 21A may also be used.

[0039] 7(a) and (b), the cooling unit 30 is shaped like a thin tube (cylindrical in the illustrated example) in the thickness direction of the sheet-like portion 20A. The cooling unit 30 may be attached to the sheet-like portion 20A by a unit attachment member 33. A flange-shaped portion 31 that protrudes radially outward is provided around the entire circumference at an axially intermediate portion of the cooling unit 30. A male thread portion 32 that screws into a female thread portion 35 formed on the inner circumference of the unit attachment member 33 is formed on the outer periphery of the heat dissipation side (the back body 12 side) of the flange-shaped portion 31 of the cooling unit 30. The unit mounting member 33 is formed in a ring shape (annular shape), and a flange-like portion 34 that protrudes radially outward is provided around the entire circumference on one axial side edge of the unit mounting member 33. The sheet-like portion 20A is sandwiched between the flange-like portion 34 of the unit mounting member 33 and the flange-like portion 31 of the cooling unit 30, and the cooling unit 30 is mounted to the sheet-like portion 20A.

[0040] In the illustrated example, the sheet-like portion 20A is provided with an insertion hole 29 through which the heat-dissipating portion of the cooling unit 30 is inserted. However, if the sheet-like portion 20A is formed of a flexible and breathable material as described above, the sheet-like portion 20A may cover the heat-dissipating portion of the cooling unit 30 and be attached by the unit mounting member 33 without providing such an insertion hole 29. This configuration allows the cooling unit 30 to be attached to any position on the sheet-like portion 20A. In this case, the cooling unit 30 may be attached to the sheet-like portion 20A by engaging the male thread portion 32 of the cooling unit 30 with the female thread portion 35 of the unit mounting member 33. Various other embodiments may also be used to attach the cooling unit 30 to the sheet-like portion 20A. The different configurations of the upper garments 2, 2A and the upper garments 1, 1A with a blower according to the above-described embodiments may be modified, rearranged, or combined as needed. For example, the cooling unit 30 may be attached to the sheet-like portion 20 of the upper garment 2 (the upper garment 1 with a blower) described in the first embodiment.

[0041] In the above examples, the long-sleeved tops 2, 2A are illustrated, but short-sleeved tops or sleeveless tops (vests) may also be used. In each of the above examples, examples are shown in which holding portions 21, 21, 21A, 21A are provided on the sheet-like portions 20, 20A so that they are positioned closer to the center than the shoulder joints 25, 25 on both sides, but instead of or in addition to these, a configuration may be used in which holding portions are provided to hold spacers 6, 6 along the shoulder portions. In each of the above examples, the upper edge 24 of the sheet-like portion 20, 20A is aligned along the upper edge 14 of the back body 12, but the upper edge 24 of the sheet-like portion 20, 20A may also be positioned above or below the upper edge 14 of the back body 12.

[0042] In the above examples, both ends (25, 26) of the sheet-like portions 20, 20A are joined to relatively upper end portions of the back body 12, but this is not limited to this. The sheet-like portions 20, 20A may be extended further downward, with both ends joined to corresponding portions of the back body 12. Alternatively, instead of or in addition to the sheet-like portions 20, 20A, a sheet-like portion generally similar to the above may be provided to bridge both ends of the back body 12 below the armholes 16, 16. In the above examples, the blower 3 has a flange 5 on the suction port side, but the blower 3 may not have such a flange 5. Furthermore, the blower 3 is not limited to a substantially cylindrical configuration, and may have a substantially rectangular cylindrical configuration. Furthermore, the locations and number of the blowers 3 are not limited to the above examples. The specific configurations of the members and parts of the upper garment 2, 2A according to each of the above-described embodiments and the upper garment 1, 1A with a blower including the upper garment 2, 2A are merely examples, and various other modifications are possible.
