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. In such jackets, if air leaks from the front opening while the blower is running, the cooling effect is reduced. For this reason, for example, the air-conditioning garment disclosed in Patent Document 1 below has a front-opening garment body with an opening and closing part such as a zipper that opens and closes the front. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-53567 Summary of the Invention [Problem to be solved by the invention]

[0004] However, while closing the front opening of the clothing body with a zipper as described above can prevent air from leaking from the front opening, it makes it difficult to pull out string-like members such as the lanyard of a safety belt (fall arrest device) that is attached inside the clothing body.

[0005] The present disclosure has been made in consideration of the above-mentioned situation, and aims to provide an upper garment that makes it difficult for air to leak from the front opening side while still allowing string-like members, etc. to be pulled out, and an upper garment equipped with an air blower that is equipped with the same. [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 to which a blower that takes in outside air is attached, and is characterized by comprising an opening / closing section that is arranged along at least the lower portions of the front opening side ends of each of the left and right front bodies, and that allows at least the lower portions of these front opening side ends to be opened and closed freely, and a strip-shaped sheet member whose first widthwise end is fixed on the back side of the left and right front bodies so as to be along at least the upper portions of each of the front opening side ends, and whose free end side on the second widthwise end side displaces from the back side toward the wearer when the blower is driven and comes into contact with an object to be abutted.

[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 belt-shaped sheet member may be provided over substantially the entire length of the front opening side end of each of the left front body piece and the right front body piece. <Configuration 3> In configuration 1 or 2, one of the belt-shaped sheet members of the left front body and the right front body may have a fastening portion at a mid-lengthwise position thereof that can be fastened to a fastening portion provided at a mid-length position of the other. <Configuration 4> In any one of configurations 1 to 3, the opening and closing portion may be a linear fastener provided over substantially the entire length of the front opening side end of each of the left front body piece and the right front body piece. <Configuration 5> In any one of configurations 1 to 4, a fastening portion may be provided at the upper end of one of the front opening side ends of the left front body and the right front body, which is fastened to a fastening portion provided at the upper end of the other.

[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, which makes it difficult for air to leak from the front opening side while still allowing string-like members, etc. to be pulled out. [Brief explanation of the drawings]

[0010] [Figure 1] 1A and 1B are schematic front views showing an example of an upper garment according to an embodiment of the present disclosure and an example of an upper garment equipped with a blower including the upper garment; [Figure 2] 2(a) is a schematic front view of the upper garment, and FIG. 2(b) is a schematic cross-sectional view taken along the line XX in FIG. 2(a). [Figure 3] FIG. 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 3 are diagrams schematically showing an example of an upper garment according to the present embodiment and an example of an upper garment equipped with a blower including the upper garment. As shown in Fig. 1(b), 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 16 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 can take in outside air into the upper garment 1 with a blower, thereby cooling the body of a wearer 6 (see Fig. 2(b)).

[0013] As shown in FIGS. 1(a) and 1(b), the front body portion 10 of the top 2 is separated into a left front body portion 10A and a right front body portion 10B. In other words, the top 2 is a front-opening type. As shown in FIGS. 1(b) and 2(a) and 2(b), the top 2 is provided with opening / closing portions 12, 12 that are provided along at least the lower portions of the front-opening side ends 11, 11 of the left front body portion 10A and the right front body portion 10B, respectively, and that allow at least the lower portions of these front-opening side ends 11, 11 to be opened and closed. With this configuration, by closing the lower portions of the front-opening side ends 11, 11 with the opening / closing portions 12, 12 at least in the lower portions of the front-opening side ends 11, 11, it is possible to prevent air from leaking from the lower portions of the front-opening side ends 11, 11 when the air blower 3 is driven.

[0014] The upper garment 2 is provided with strip-shaped sheet members 13, 13, each having a first widthwise end 13a fixed to the back surface of the left front body piece 10A and the right front body piece 10B so as to follow at least the upper portions of the respective front-opening side ends 11, 11, and whose free ends at the second widthwise end 13b side are displaced from the back surface side toward the wearer 6 and come into contact with an abutment object when the air blower 3 is driven. With this configuration, at least in the upper portions of the front-opening side ends 11, 11, when the air blower 3 is driven, the second ends 13b, which are the free ends of the strip-shaped sheet members 13, 13 of the left front body piece 10A and the right front body piece 10B, come into contact with the abutment object, thereby blocking the airflow and thereby making it difficult for air to leak from the upper portions of the front-opening side ends 11, 11. As a result, the space between the band-like sheet members 13, 13 on both sides of the upper portion of the front-opening side ends 11, 11 can be used as a pull-out section for a string-like member 7 (see FIG. 2(b)), such as a lanyard for a safety belt (a fall arrest device), eliminating the need to provide a pull-out hole in the front body 10 of the top 2 and effectively increasing the range of motion of the string-like member 7 relative to the front body 10 of the top 2. As a result, compared to a configuration in which a pull-out hole is provided in the front body 10 of the top 2, for example, the top 2 is less likely to ride up even when the string-like member 7 is pulled upward, improving comfort.

[0015] 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 top 2 comprises a left front body 10A and a right front body 10B that constitute the front body 10, a back body 15, a collar 18, and left and right sleeves 19, 19. The front body 10 and the back body 15 are joined by stitching or the like, and the collar 18 and the left and right sleeves 19, 19 may also be joined to the front body 10 and the back body 15 by stitching or the like. In the illustrated example, a pocket is provided on the surface side of each of the left front body 10A and the right front body 10B, but this is not a limitation. The lower end of the top 2 (front body 10 and back body 15) is provided with a hem 17 configured to fit snugly against the wearer's body or clothing such as underwear 6. This hem 17 forms a drawstring that prevents air from leaking downward. Such hem 17 may be configured to include a stretchable material such as rubber. This hem 17 may be joined to the lower edges of the front body 10 and back body 15 by stitching or the like.

[0016] As shown in FIG. 1(b), the attachment holes 16 of the top 2 are provided in the back body 15. More specifically, two attachment holes 16, 16 are provided in the back body 15. These attachment holes 16, 16 are provided so as to penetrate through the back body 15. In the illustrated example, these attachment holes 16, 16 are substantially circular when viewed in the thickness direction of the back body 15 (viewed in the penetration direction). These attachment holes 16, 16 have the same diameter. These mounting holes 16, 16 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 16, 16 are provided at positions that are symmetrical with respect to the center line that passes through the center of the back body 15 in the left-right direction.

[0017] The height positions (vertical positions) at which these mounting holes 16, 16 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, work content, working posture, etc. of the wearer 6 wearing the upper garment 2 (upper garment 1 with air blowers). In the illustrated example, these mounting holes 16, 16 are shown provided at height positions close to the waist, which is the lower part of the back body 15 in the vertical direction. Instead of such positions, these mounting holes 16, 16 may be provided at the center or upper part of the back body 15 in the vertical direction. Appropriate reinforcing sheets may be provided around the attachment holes 16, 16 of the upper garment 2 (back body piece 15) to reinforce the periphery of the attachment holes 16, 16. Such reinforcing sheets may be in the form of circular plates surrounding the attachment holes 16, 16, or in the form of rectangular plates with holes corresponding to the attachment holes 16, 16. 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 piece 15). These reinforcing sheets may be fixed along the back surface (the surface facing the wearer 6, the inner surface) of the back body piece 15, or may be enclosed between the outer fabric and lining that constitute the back body piece 15.

[0018] The air blowers 3, 3 attached to the respective attachment holes 16, 16 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 6), 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] A flange 5 that protrudes radially outward along the entire circumference is provided on the suction port side peripheral edge, which is the surface side of the cylindrical portion 4 of the blower 3. The outer diameter of this flange 5 is larger than the inner diameter of the mounting hole 16. 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 16. 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 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, a holder for holding an intermediate portion of the power cord, and the like.

[0021] In this embodiment, the opening and closing sections 12, 12 are linear fasteners provided along the front opening side edges 11, 11, which are the butt ends of the left front body piece 10A and the right front body piece 10B. With this configuration, air leakage from the front opening side at least in the lower region can be effectively reduced compared to, for example, a configuration in which the opening and closing sections are multiple fasteners such as buttons provided at intervals along the front opening side edges 11, 11. The opening and closing sections 12, 12 are linear fasteners provided over substantially the entire length (almost the entire length in the direction of the height of the wearer 6) of the front opening side end sections 11, 11 of the left front body section 10A and the right front body section 10B. With this configuration, the front opening side end sections 11, 11 can also be closed over substantially the entire length by the opening and closing sections 12, 12.

[0022] The linear fastener (slide fastener) used as the opening / closing sections 12, 12 may be joined to each front-opening side end 11, 11 by stitching or the like, and may have elements (teeth) at the butting end portions thereof that interlock with each other, with a slider on one side for engaging and disengaging the elements. Such opening / closing sections 12, 12 may also be a so-called double (reverse opening) fastener with two sliders. In this case, instead of or in addition to the configuration in which the fastening section 10a and the fastening section 10b described below are provided at the upper end, similar fastening section 10a and fastening section 10b may be provided at the lower end. Instead of or in addition to the linear fastener, the opening / closing sections 12, 12 may be provided with other opening / closing sections. For example, the opening and closing sections 12, 12 may be hook and loop fasteners provided along the front opening side edges 11, 11, which are in the vicinity of the overlapping front seam (front placket) portion, or may be multiple fasteners provided at intervals along the front opening side edges 11, 11. The fasteners may be, for example, buttonholes and buttons fastened to the buttonholes, upper and lower snap buttons (dot buttons), or hooks and hook hooks.

[0023] As shown in Figures 1(a) and 2(a), one of the front-opening side ends 11, 11 of the left front body piece 10A and the right front body piece 10B has a fastening portion 10a at the upper end thereof that fastens to a fastening portion 10b at the upper end thereof. With this configuration, even when the upper portions of the front-opening side ends 11, 11 are opened to block the airflow with the band-shaped sheet members 13, 13, the front-opening side can be prevented from opening excessively, and air leakage from the front-opening side can be more effectively reduced. The fastening portion 10a and the fastening portion 10b are provided on the front surface side of the front opening side end portions 11, 11 of the left front body piece 10A and the right front body piece 10B. In the illustrated example, one end of a flap-like piece 14 is joined by sewing or the like to the front surface side of the front opening side end portion 11 of the left front body piece 10A, and the fastening portion 10a is provided at the other end portion of the flap-like piece 14. The flap-like piece 14 is configured so that the other end, which is the free end, can be displaced like a flap, using one end as a fulcrum. When the fastening portion 10a of the flap-like piece 14 is fastened to the fastening portion 10b of the right front body piece 10B, as shown in FIG. 2(a), the flap-like piece 14 spans between the upper ends of the front opening side end portions 11, 11 of the left front body piece 10A and the right front body piece 10B, preventing the upper ends of the left front body piece 10A and the right front body piece 10B from opening.

[0024] The fastening portion 10a and the fastened portion 10b may be provided so as to be positioned from the upper end of the front-opening side end portions 11,11 to the upper and lower quarters of the front-opening side end portions 11,11. In the illustrated example, two fastening portions 10a are provided on the flap-like piece 14, and two fastening portions 10b are provided on the front side of the front opening side end 11 of the right front body piece 10B, but a configuration with three or more fastening portions 10a and one fastening portion 10b may also be provided. Such fastening portions 10a and fastening portions 10b may be the same as the fasteners described above, one may be an upper type of snap button (dot button) and the other a lower type, or may be a hook and loop fastener, a buttonhole and button, a hook and hook hook, etc. Furthermore, a configuration without such fastening portions 10a and fastening portions 10b may also be provided.

[0025] The left and right strip-shaped sheet members 13, 13 are elongated and extend along the front opening side ends 11, 11 of the left front body piece 10A and the right front body piece 10B. In this embodiment, the strip-shaped sheet members 13, 13 are provided over substantially the entire length of the front opening side ends 11, 11 of the left front body piece 10A and the right front body piece 10B. This configuration makes it difficult for air to leak from the front opening side even when most of the front opening side ends 11, 11 are open, and also allows for a greater range of motion of the string-like members 7 relative to the upper garment 2. A fastening portion 13c is provided at a midpoint in the longitudinal direction of one of the strip-shaped sheet members 13, 13 of the left front body portion 10A and the right front body portion 10B, which is fastened to a fastening portion 13d provided at a midpoint in the other. With this configuration, by fastening the midpoints in the longitudinal direction of the left and right strip-shaped sheet members 13, 13 together, it is possible to prevent the front-opening side from opening excessively, and it is possible to more effectively reduce air leakage from the front-opening side.

[0026] Specifically, these strip-shaped sheet members 13, 13 may be made of an appropriate soft, low-breathability (or non-breathable) cloth material, etc., similar to the left front body portion 10A and the right front body portion 10B, or may be an appropriate synthetic resin sheet, etc. A high-friction material that increases frictional resistance may be provided at the portion of the second end portions 13b, 13b of these strip-shaped sheet members 13, 13 that comes into contact with the contact object, or an appropriate surface treatment may be applied to increase the frictional resistance. These strip-shaped sheet members 13, 13 have first ends 13a, 13a fixed to the back sides of the left and right front-opening end portions 11, 11 as a fulcrum, and second ends 13b, 13b on the free end side, that are displaceable like a flap. The first ends 13a, 13a of these strip-shaped sheet members 13, 13 may be joined to the back sides of the left and right front-opening end portions 11, 11 or to the so-called inside edges by stitching, adhesive, tape, etc. These strip-shaped sheet members 13, 13 may be formed continuously with the inside edges provided on the back sides of the left and right front-opening end portions 11, 11, i.e., the inside edges may be configured to be wide.

[0027] These strip-shaped sheet members 13, 13 are strip-shaped with their width direction aligned with the circumferential direction of the torso of the wearer 6. The width dimension of these strip-shaped sheet members 13, 13 (the width dimension of the displaceable portion) may be, for example, approximately 50 mm to 250 mm, or approximately 100 mm to 200 mm. In the illustrated example, the strip-shaped sheet members 13, 13 have a substantially uniform width along their entire length, but this is not limited to this. For example, the width dimension of the strip-shaped sheet members 13, 13 may increase from the upper end to the lower end, or from the lower end to the upper end. Furthermore, the strip-shaped sheet members 13, 13 may have a portion with a larger width or a portion with a smaller width in the middle of their longitudinal direction. For example, the width dimension of the strip-shaped sheet members 13, 13 at the longitudinal center portion, which serves as the lead-out portion for the string-shaped members 7, may be larger than the widths above and below it. The upper and lower ends of these belt-shaped sheet members 13, 13 may be joined by sewing or the like to the back side of each front-opening side end 11, 11 (the back side of the front body 10, collar 18, hem 17, etc.), or both or one of the upper and lower ends may be unjoined to the back side of each front-opening side end 11, 11.

[0028] The fastening portion 13c and the fastening portion 13d are provided at the upper end portions of the band-shaped sheet members 13, 13. With this configuration, by fastening these fastening portions 13c and fastening portion 13d, when the central portion in the vertical direction is used as the pull-out portion of the string-like member 7, excessive opening of the front opening side above that portion can be prevented. Furthermore, by providing the fastening portions 10a and fastening portions 10b at the upper ends of the front opening side ends 11, 11 of the left front body portion 10A and the right front body portion 10B as described above, the fastening portions 13c and fastening portions 13d at the upper end portions of the band-shaped sheet members 13, 13 can more reliably prevent the front opening side from opening excessively. Furthermore, if at least the opening / closing portions 12, 12 in the lower portion are linear fasteners as described above, opening of the front opening side in the lower portion can be reliably prevented, which is preferable when the central portion in the vertical direction is used as the pull-out portion of the string-like member 7, as shown in FIGS. 2(a) and 2(b). In other words, in the vertical central portion and the upper side thereof, which is the pull-out portion of the string-like member 7, air leakage can be suppressed by the left and right strip-like sheet members 13, 13, and the front-opening side of the upper end portion can be prevented from opening excessively by the fastening portion 10a and the fastening portion 10b, and the fastening portion 13c and the fastening portion 13d, and in the lower portion of the pull-out portion, air leakage can be suppressed by the opening and closing portions 12, 12.

[0029] These retaining portions 13c and retaining portions 13d may be arranged to be located from the upper end of the front-opening side end portions 11, 11 to the upper and lower quarters of the front-opening side end portions 11, 11, similar to the retaining portions 10a and 10b described above. As with the fastening portion 10a and the fastening portion 10b, one of the fastening portions 13c and the fastening portion 13d may be an upper type of snap button (dot button) and the other a lower type, or alternatively, they may be hook-and-loop fasteners, buttonholes and buttons, hooks and hook hooks, etc. In the illustrated example, the fastening portion 13c and the fastening portion 13d are shown positioned slightly lower than the fastening portion 10a and the fastening portion 10b, but this is not intended to be limiting. In addition, in the illustrated example, the fastening portion 13c and the fastening portion 13d are shown positioned approximately at the center in the width direction of each strip-shaped sheet member 13, 13, but this is not intended to be limiting, and they may be positioned closer to the second end portions 13b, 13b than the center in the width direction. In addition, the illustrated example shows an example in which one fastening portion 13c is provided on the left-hand strip-shaped sheet member 13, which is one of the left and right strip-shaped sheet members 13, 13, and one fastening portion 13d is provided on the right-hand strip-shaped sheet member 13, which is the other, but the positions and numbers of the fastening portions 13c and fastening portions 13d are not limited to this example.

[0030] When using the upper garment 2 (upper garment 1 with air blower 3) having the above-described configuration attached, the upper garment 2 is put on and the front opening is opened, closed, or fastened as appropriate depending on whether a fall arrest device is attached and the wearer's 6's preferences. For example, if the string-like member 7 of the fall arrest device does not need to be pulled out from the front, the air blower 3 may be driven with the openings 12, 12 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 intake of the air blower 3, and prevents air leakage from the front opening and the hem 17, thereby forming an air circulation space between the wearer 6 (see FIG. 2(b)) and the inner surface of the upper garment 2, thereby cooling the wearer 6. The air drawn into the upper garment 2 is exhausted from exhaust ports, such as between the collar 18 and the neck and at the cuffs of the sleeves 19, 19.

[0031] On the other hand, when it is necessary to pull out the string-like member 7 of the fall arrest device from the front side, as shown in Figure 2(a), the opening and closing parts 12, 12 may be closed from the bottom end to a vertically intermediate portion, and the air blower 3 may be driven and used with the fastening part 10a and fastening part 10b and the fastening part 13c and fastening part 13d fastened. In other words, the vertically central portion of the front-opening side end parts 11, 11 is not closed or fastened by the opening and closing parts 12, 12, fastening parts 10a, 13a, fastening parts 10b, 13b, etc., and is in an open state. Even when the vertical center portions of the front-opening side ends 11 are open, as shown in FIG. 2(b), outside air taken into the upper garment 2 through the inlet of the air blower 3 displaces the left and right strip-shaped sheet members 13 so that they rise from the rear surfaces of the front-opening side ends 11, causing the second ends 13b to abut against an abutment object along substantially their entire length. This blocks the airflow with the left and right strip-shaped sheet members 13, thereby suppressing air leakage from the front-opening side. The abutment object on the second ends 13b may be the body or underwear of the wearer 6, or the other strip-shaped sheet member 13. In other words, the second end portions 13b of the strip-shaped sheet members 13 may abut against each other to prevent air leakage from the front-opening side. Furthermore, when the string-like member 7 is pulled out, the second end portions 13b, 13b of the left and right strip-like sheet members 13, 13 come into close contact with the string-like member 7, thereby preventing air from leaking from the pulled-out portion of the string-like member 7. As a result, as in the above, the wearer 6 can be cooled by the air taken into the upper garment 2, and the air taken into the upper garment 2 is discharged from discharge portions such as between the collar 18 and the neck and at the cuffs of the sleeves 19, 19.

[0032] 3, the opening / closing portions 12, 12 may be closed from the bottom to a vertically intermediate position, with the fastening portion 10a and the fastening portion 10b left untucked and the fastening portion 13c and the fastening portion 13d fastened, and the air blower 3 driven and used. This configuration facilitates the air drawn into the upper garment 2 to be expelled upward toward the front, i.e., toward the face. In this case, the upper garment can also be used without fastening the fastening portion 13c and the fastening portion 13d. Even in this case, the left and right strip-shaped sheet members 13, 13 are displaced to stand up from the rear surfaces of the front-opening side ends 11, 11, and come into contact with the object of contact, thereby blocking the airflow and preventing air leakage from the front-opening side. Furthermore, appropriate spacers or the like may be provided at appropriate locations on the inner surface of the upper garment 2 to ensure air circulation space.

[0033] In the above example, the fastening portion 13c and the fastening portion 13d are provided in the middle of the belt-shaped sheet members 13, 13, but such fastening portion 13c and fastening portion 13d may not be provided. In addition, a string-like member or the like may be provided at an appropriate position in the longitudinal direction of the left and right strip-shaped sheet members 13, 13 to connect the second end portions 13b, 13b side with the back side of the front body 10 so as to suppress further displacement from the upright state (excessive displacement on the second end portions 13b, 13b side). In the above example, the opening and closing sections 12, 12 are provided over almost the entire length of the front-opening side end sections 11, 11, but they may be provided at least in the lower part, and for example, they may be provided so that the opening and closing sections can be closed from the lower end of the front-opening side end sections 11, 11 to the upper and lower half or quarter of the front-opening side end sections 11, 11.

[0034] In the above example, the left and right strip-shaped sheet members 13, 13 are provided over approximately the entire length of the front-opening side end portions 11, 11, but they may be provided at least in the upper portion, and if the opening and closing portions 12, 12 are provided from the lower end to an intermediate portion as described above, they may be provided so that the upper end side of the opening and closing portions 12, 12 at least overlaps with the lower end side of the strip-shaped sheet members 13, 13. In the above example, the top 2 has long sleeves, but it may also be a top with short sleeves or a sleeveless top (vest). The specific configurations of the members and parts of the upper garment 2 according to the embodiment and the upper garment 1 with a blower including the same are merely examples, and various other modifications are possible.
