[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0010] Figure 1 is a developed view of an outer garment 1 as a clothing article according to an embodiment of the present invention, viewed from the inner surface side of a wearer. Hereinafter, the up-down, left-right, and front-back directions of the outer garment 1 are defined based on the state where the wearer wearing the outer garment 1 stands upright. Further, the direction from the outer surface toward the inside in the thickness direction of the fabric is defined as the inner side, and the opposite direction is defined as the outer side; the direction toward the outer side in the width direction is defined as the outer side, and the direction toward the center side in the width direction is defined as the inner side.

[0011] Referring to Figure 1, the outer garment 1 is formed of, for example, a woven fabric and / or a knitted fabric. The outer garment 1 has at least a front body 2 and a back body 3, and may further include, for example, a sleeve portion, a collar portion and / or a hood portion. The front body 2 and the back body 3 respectively refer to portions that cover the front and back of the wearer, and the front body 2 and the back body 3 are divided at both outer sides in the width direction. The pre-sewing patterns constituting the outer garment 1 do not necessarily have to be formed to match the division between the front body and the back body, the front body and the back body may each include two or more patterns, and the front body and the back body may be integrally formed.

[0012] In the present embodiment, the underarm point 91, the waist line 92, the scapula 93, and the scapular spine 93a conform to JIS L0111:2006 Body Terminology for Clothing. For each of the above lines and points, the anterior axillary point 91, the waist line 92, the scapula 93, and the scapular spine 93a of a prescribed mannequin (a mannequin manufactured by Shichisei Co., Ltd.: MD-20A (Men's)) when the outer garment 1 is put on the mannequin may be applied.

[0013] The outer garment 1 has a plurality of protrusions 5 protruding from the back body 3 toward the inner surface side. The spaces between the plurality of protrusions 5 define spaces through which air can flow between the back body 3 and the wearer.

[0014] Figure 3 shows a cross-section perpendicular to the extension direction of the third and fourth protrusions 53 and 54, which will be described later. Referring to Figure 3, in this embodiment, the protrusion 5 has a core material 5a, a base portion 5b for attaching the core material 5a to the back body 3, and a cover fabric 5c that encloses the core material 5a and the base portion 5b. The base portion 5b is a knitted fabric, for example, made of 100% polyester. The cover fabric 5c is a woven fabric with urethane foam laminated onto a waterproof and moisture-proof fabric, for example, made of 100% polyester. Here, the third and fourth protrusions 53 and 54 will be described, but the multiple protrusions 51, 52, 55, and 56 have a similar configuration and will therefore not be described.

[0015] The protrusion 5 is formed by fixing a core material 5a to one side surface 5b1 of the base portion 5b with an adhesive member (not shown), wrapping the cover fabric 5c around the integrated base portion 5b and core material 5a from one side surface 5b1, and fixing the cover fabric 5c to the base portion 5b with an adhesive member (not shown). The other side surface 5b2 of the base portion 5b is bonded to the inner surface (wearer side) of the back body 3 with an adhesive member (not shown), thereby fixing the protrusion 5 to the back body 3.

[0016] The core material 5a preferably has a predetermined compressibility, a predetermined height, and a predetermined length. In this embodiment, the cross-section of the core material 5a in the direction perpendicular to the extending direction is rectangular and is a crosslinked foam of styrene-based elastomer, etc. For example, the core material 5a can be Pitafoam manufactured by Daiichi Chemical Co., Ltd. The core material 5a may also be, for example, ethylene vinyl acetate copolymer resin (EVA) or urethane foam (product name: PORON, etc.).

[0017] The width W11 in the direction perpendicular to the extension direction of the protrusion 5 is preferably 5 mm or more and 30 mm or less, for example, 10 mm.

[0018] The protrusion 5 has a predetermined protrusion amount H1 that extends inward from the back panel 3. The protrusion amount H1 is preferably 5 mm or more and 13 mm or less, for example, 10.5 mm. The predetermined protrusion amount H1 may be a value such that the protrusion amount H2 of the deformed protrusion 5 (first to sixth protrusions 51, 52, 53, 54, 55, 56) is 5 mm or more when a predetermined load is applied to the area shown by the dashed line in Figure 1. In this embodiment, the predetermined load is, for example, the load that acts on the wearer's back when carrying a mountaineering backpack, for example, 7 kg.

[0019] The compression ratio of the protrusion 5 is preferably 33% to 62%, for example, 55%. In this embodiment, the compression ratio is the ratio of the deformation allowance ΔH of the deformed protrusion 5 to the amount of protrusion H1 of the protrusion 5 before deformation, when a predetermined load is applied to the entire protrusion 5 of one or more protrusions 5. The predetermined load is, for example, the load acting on the back of the wearer when carrying a mountaineering backpack, for example, 7 kg.

[0020] As shown in Figure 1, the protrusion 5 has a first protrusion 51 positioned in the center of the width direction of the back panel 3 and extending vertically along the center line CL, and a pair of second to sixth protrusions 52, 53, 54, 55, and 56 positioned on either side of the center line CL. Each protrusion 5 is a long member. The pair of second to sixth protrusions 52, 53, 54, 55, and 56 on the left and right sides are inclined upward from the outside in the width direction toward the inside (center line). The distance between adjacent protrusions among the multiple protrusions 51, 52, 53, 54, 55, and 56 is between 45 mm and 145 mm.

[0021] In this specification, the vertical dimension L1 of the back panel 3 is divided into four equal parts, and from top to bottom, these are divided into the first region R1, the second region R2, the third region R3, and the fourth region R4. The vertical dimension L1 of the back panel 3 is the vertical dimension between the neckline 3a and the hem 3b on the center line CL. Note that the left and right pairs of second to sixth protrusions 52, 53, 54, 55, and 56 are symmetrical with respect to the center line CL, so the left second to sixth protrusions 52, 53, 54, 55, and 56 will be described, and the description of the right protrusion will be omitted.

[0022] As shown in Figure 2, the first protrusion 51 is positioned above the vertical center of the back panel 3. The first protrusion 51 is located in the second region R2. The first protrusion 51 extends vertically along the center line CL. The height of the upper end 51a of the first protrusion 51 roughly coincides with the upper end of the second region R2. The lower end 51b of the first protrusion 51 is located above the lower end of the second region R2. The height of the upper end 51a of the first protrusion 51 roughly coincides with the height of the armpit point 91 of the wearer 9. The height of the lower end 51b of the first protrusion 51 is located above the waistline 92 of the wearer 9.

In particular, the outer end portion 52a of the second protrusion 52 on the outer side in the width direction is located adjacent to the upper part of the scapular spine 93a. The scapular spine 93a is a raised portion located on the upper back of the scapula 93 and extending in the width direction. The inclination angle α1 of the second protrusion 52 with respect to a straight line parallel to the width of the body is preferably set to 40 degrees or more and 60 degrees or less, for example, 50 degrees.

[0024] The third protrusion 53 is positioned as a whole in the upper portion of the second region R2. The third protrusion 53 has a third outer inclined portion 53a that slopes upward toward the inside in the width direction, and a third inner inclined portion 53b that slopes further inward toward the inside from the inner end of the third outer inclined portion 53a.

[0025] At least a portion of the third inner inclined portion 53b protrudes above the height position of the upper end of the second region R2. The third outer inclined portion 53a is located in the second region R2.

[0027] The third protrusion 53 is positioned on the lower part of the wearer's scapula 93, overlapping both vertically and horizontally. More specifically, the third protrusion 53 is positioned below the scapular spine 93a. The third protrusion 53 is positioned in the depression (infraspinous fossa) of the scapula 93 located below the scapular spine 93a. The second protrusion 52 and the third protrusion 53 are positioned so as to sandwich the scapular spine 93a from above and below. The second protrusion 52 and the third protrusion 53 are positioned offset vertically from the scapular spine 93a. It is preferable that the second protrusion 52 and the third protrusion 53 do not overlap the scapular spine 93a even when the scapula 93 is movable. In particular, if the third protrusion 53 and the scapular spine 93a overlap, discomfort may occur.

[0028] The fourth protrusion 54 is located in the central part of the second region R2 in the vertical direction. The fourth protrusion 54 is located opposite to the lower part of the third outer inclined portion 53a. The outer end 54a of the fourth protrusion 54 in the width direction is located below the lowest point 11a (Figure 1) of the armhole 11. The inclination angle α4 of the fourth protrusion 54 with respect to a straight line parallel to the width of the body is preferably set to 35 degrees or more and 55 degrees or less, for example, 45 degrees.

The outer end portion 55d of the fifth outer inclined portion 55a is located above the waistline 92, and the fifth curved portion 55c is located above the waistline 92, roughly at the lower end of the second region R2.

[0031] The fifth inward inclined portion 55b is located between the first protrusion 51 and the third protrusion 53 in the width direction. The upper end 55e of the fifth protrusion 55, the upper end 51a of the first protrusion 51, the upper end 53c of the third protrusion 53, and the upper end 54b of the fourth protrusion 54 are positioned offset from each other. The upper end 55e of the fifth inward inclined portion 55b is located above the upper end 54b of the fourth protrusion 54, and below the upper end 51a of the first protrusion 51 and the upper end 53c of the third protrusion 53.

[0032] The inclination angle α5 of the fifth outer inclined portion 55a with respect to a straight line parallel to the width of the body is preferably set to 15 degrees or more and 35 degrees or less, for example, 25 degrees. The inclination angle α6 of the fifth inner inclined portion 55b with respect to a straight line parallel to the width of the body is preferably set to 80 degrees or more and 90 degrees or less, for example, 85 degrees. The inclination angle α6 of the fifth inner inclined portion 55b is greater than the inclination angle α5 of the fifth outer inclined portion 55a.

[0033] The sixth protrusion 56 is positioned as a whole on the upper part of the third region R3. The sixth protrusion 56 has a sixth outer inclined portion 56a that inclins upward toward the inside in the width direction, a sixth inner inclined portion 56b that inclins further toward the inside from the inner end of the sixth outer inclined portion 56a, and a sixth curved portion 56c that connects the sixth outer inclined portion 56a and the sixth inner inclined portion 56b.

[0034] The outer end 56d of the sixth outer inclined portion 56a is located below the waistline 92. The sixth inner inclined portion 56b and the sixth curved portion 56c are located above the waistline 92. The upper end 56e of the sixth inner inclined portion 56b is located at the lower end of the second region R2.

[0035] As shown in Figure 2, the sixth protrusion 56 is approximately parallel to the fifth protrusion 55. More specifically, the sixth outer inclined portion 56a, the sixth inner inclined portion 56b, and the sixth curved portion 56c are approximately parallel to the fifth outer inclined portion 55a, the fifth inner inclined portion 55b, and the fifth curved portion 55c, respectively.

The inclination angle α8 of the sixth inner inclined portion 56b with respect to a straight line parallel to the width of the body is preferably set to 65 degrees or more and 85 degrees or less, for example, 75 degrees. The inclination angle α8 of the sixth inner inclined portion 56b is greater than the inclination angle α7 of the sixth outer inclined portion 56a.

[0037] As shown in Figure 1, the back panel 3 has a ventilation section 7 that connects the inside and outside of the upper garment 1, and a plurality of ventilation passages 6 for guiding the air inside the upper garment 1 to the ventilation section 7.

[0038] In this embodiment, the ventilation section 7 is a plurality of ventilation openings 71 formed by, for example, punching, that connect the inner surface and outer surface of the back body 3. The ventilation section 7 is provided below the neckline 3a of the back body 3, along the center line CL in the first region R1. The ventilation section 7 is positioned between the inner ends 52b of a pair of left and right second protrusions 52. The ventilation section 7 is provided between a pair of left and right scapulae 93 of the wearer 9.

[0039] The multiple ventilation passages 6 include a vertical ventilation passage 60 that extends generally in the vertical direction and an inclined ventilation passage that extends upward from the outside in the width direction toward the inside. The multiple ventilation passages 6 are formed by the first to sixth protrusions 51, 52, 53, 54, 55, and 56.

[0040] The vertical ventilation passage 60 extends vertically along the center line CL in the center of the body width direction. The vertical ventilation passage 60 extends from near the wearer's waist (third region R3) to below the neckline 3a (first region R1) and communicates with the ventilation section 7.

[0041] More specifically, the vertical ventilation passage 60 is formed between the left and right pair of sixth protrusions 56, between the left and right pair of fifth protrusions 55, between the left and right pair of fifth protrusions 55 and the first protrusion 51, between the left and right pair of third protrusions 53, and between the left and right pair of second protrusions 52.

[0042] The vertical ventilation passage 60 narrows in width from between the pair of left and right sixth protrusions 56 towards the space between the pair of left and right fifth protrusions 55 and the first protrusion 51 (from bottom to top), and widens in width from the upper ends 55e of the pair of left and right fifth protrusions 55 towards the ventilation section 7 (upwards). Air flowing into the vertical ventilation passage 60 from below the jacket 1 is guided to the ventilation section 7.

[0043] In this embodiment, the shortest distance in the width direction of the vertical ventilation passage 60 between the left and right pair of second protrusions 52 (the distance between the inner ends 52b of the left and right pair of second protrusions 52) W5 is 160 mm. In this embodiment, the width dimension W of the back panel 3 when laid flat is 600 mm, so the ratio of the shortest distance W5 in the width direction between the left and right pair of second protrusions 52 to the width dimension W of the back panel 3 is 26.7%.

[0044] The shortest distance W6 in the width direction of the vertical ventilation passage 60 between the left and right pair of third protrusions 53 (the distance between the upper ends 53c of the left and right pair of third protrusions 53) is 160 mm. The ratio of the shortest distance W6 in the width direction between the left and right pair of third protrusions 53 to the width dimension W of the back panel 3 when laid flat is 26.7%.

[0045] The shortest distance W7 in the width direction of the vertical ventilation passage 60 between the pair of left and right fifth protrusions 55 and the first protrusion 51 (the distance between the upper end 55e of the fifth protrusion 55 and 51) is 35 mm. The ratio of the shortest distance W7 in the width direction between the pair of left and right third protrusions 53 to the width dimension W of the back panel 3 when laid flat is 5.8%.

[0046] The distance W8 in the width direction of the vertical ventilation passage 60 between the pair of left and right fifth protrusions 55 and the lower end portion 51b of the first protrusion 51 is 45 mm. The ratio of the distance W8 to the width dimension W of the back panel 3 when laid flat is 7.5%.

[0047] The distance W9 in the width direction of the vertical ventilation passage 60 between the upper ends 56e of the pair of left and right sixth protrusions 56 is 40 mm. The ratio of the shortest distance W9 in the width direction between the pair of left and right sixth protrusions 56 to the width dimension W of the back panel 3 when laid flat is 6.7%.

[0048] The distance W10 in the width direction of the vertical ventilation passage 60 between the outer ends 56d of the pair of left and right sixth protrusions 56 is 220 mm. The ratio of the distance W10 in the width direction between the pair of left and right outer ends 56d to the width dimension W of the back panel 3 when laid flat is 36.7%.

[0049] The inclined ventilation passage is designed to connect the outer side of the wearer's body in the width direction with the vertical ventilation passage 60. In other words, the inclined ventilation passage is connected to the ventilation section 7 via the vertical ventilation passage 60.

The flow path width (vertical dimension) W1 of the first inclined ventilation passage 61 is preferably 45 mm or more and 145 mm or less, for example, 110 mm. The flow path width W1 of the first inclined ventilation passage 61 widens from the outside in the width direction toward the inside.

[0052] The second inclined ventilation passage 62 is formed between the third protrusion 53 and the fourth protrusion 54. The second inclined ventilation passage 62 extends from the upper part of the second region R2 (corresponding to the underarm area of ​​the wearer) on the outer side in the width direction toward the center line CL (Figure 1). The flow path width (vertical dimension) W2 of the second inclined ventilation passage 62 is generally constant, preferably between 45 mm and 145 mm, for example, 45 mm.

[0053] The third inclined ventilation passage 63 is formed between the fourth protrusion 54 and the fifth protrusion 55. The third inclined ventilation passage 63 extends outward in the width direction from the lower part in the vertical direction of the second region R2 to the upper part in the second region R2 and toward the centerline CL. The flow path width (vertical dimension) W3 of the third inclined ventilation passage 63 is preferably 45 mm or more and 145 mm or less, for example, 145 mm. The flow path width W3 of the third inclined ventilation passage 64 narrows from the outside in the width direction toward the inside.

[0054] The fourth inclined ventilation passage 64 is formed between the fifth protrusion 55 and the sixth protrusion 56. The fourth inclined ventilation passage 64 extends from the upper part in the vertical direction of the third region R3 to the upper end of the third region R3 and toward the centerline CL on the outer side in the width direction. The flow path width (vertical dimension) W4 of the fourth inclined ventilation passage 64 is preferably 45 mm or more and 145 mm or less, for example, 65 mm. The flow path width W4 of the fourth inclined ventilation passage 64 narrows from the outer side in the width direction toward the inner side.

[0055] As shown in Figure 2, in this embodiment, the third protrusion 53 and the fourth protrusion 54 are formed by fixing the core material 5a constituting each protrusion to a single base portion 5b. Similarly, the fifth protrusion 55 and the sixth protrusion 56 are formed by fixing the core material 5a constituting each protrusion to a single base portion 5b.

[0056] The base portion 5b of the third protrusion 53 and the fourth protrusion 54 is provided with two elongated holes 5e that extend in the direction in which the third protrusion 53 and the fourth protrusion 54 extend and penetrate the garment 1 in the inward and outward directions. The base portion 5b of the fifth protrusion 55 and the sixth protrusion 56 is provided with two elongated holes 5f that extend in the direction in which the fifth protrusion 55 and the sixth protrusion 56 extend and penetrate the garment 1 in the inward and outward directions.

[0057] Figure 4 is a diagram of the middle layer 8, worn in combination with the upper garment 1, as seen from the wearer's perspective. The upper garment 1 can be worn in combination with the middle layer 8, which is worn on the inner surface of the upper garment 1. In Figure 4, the upper garment 1 when worn in combination with the middle layer 8 is shown by a dashed line. The middle layer 8 is a garment positioned between the inner and outer layers.

[0058] As shown in Figure 4, the middle layer 8 comprises a front panel 82 and a back panel 83. The back panel 83 comprises several thermal insulation packs 85, 86, and 87. The thermal insulation packs 85, 86, and 87 are constructed by enclosing a filling material in woven and / or knitted fabric. The filling material is, for example, down, feathers, or batting. The thermal insulation packs 85, 86, and 87 are provided to enhance heat retention.

[0059] The thermal insulation packs 85, 86, and 87 consist of a first thermal insulation pack 85 located in a first region R1 on the back panel 3 of the upper garment 1, a second thermal insulation pack 86 located in a second region R2, and a third thermal insulation pack 87 located in a third region R3. The first to third thermal insulation packs 85, 86, and 87 are provided in pairs on both sides of the center line CL in the width direction of the back panel 83.

[0060] When the upper garment 1 and the middle layer 8 are worn together, it is preferable that the protrusion 5 is positioned in a location that does not overlap with the heat-retaining packs 85, 86, and 87 in a plan view.

[0061] The first thermal pack 85 is positioned between the second protrusion 52 and the third protrusion 53. The first thermal pack 85 is positioned to cover the lower portion of the scapula 93. The first thermal pack 85 has an upper edge 85a and a lower edge 85b that slope upward from the outside in the width direction toward the inside. The upper edge 85a of the first thermal pack 85 extends along the second protrusion 52. The lower edge 85b of the first thermal pack 85 extends along the third protrusion 53.

The upper edge 86a of the second insulation pack 86 extends along the fourth protrusion 54, and the lower edge 86b of the second insulation pack 86 extends along the fifth protrusion 55.

[0063] The third insulation pack 87 is located below the second insulation pack 86. The third insulation pack 87 is spaced apart from the second insulation pack 86. The third insulation pack 87 is located below the sixth protrusion 56. The upper edge 87a of the third insulation pack 87 is inclined upward toward the inside in the width direction. The upper edge 87a of the third insulation pack extends along the inclination of the sixth protrusion 56.

[0064] When the jacket 1 and middle layer 8 are worn together, the first thermal pack 85 is placed in the first inclined ventilation passage 61. The second thermal pack 86 is placed in the third inclined ventilation passage 63. The third thermal pack 87 is placed below the fourth inclined ventilation passage 64. On the other hand, since no thermal packs are placed in the second inclined ventilation passage 62 and the fourth inclined ventilation passage 64, even when the garments are worn together, the second and fourth inclined ventilation passages 62 and 64 maintain a space in which air can flow.

[0065] In other words, the vertical ventilation passage 60, the second inclined ventilation passage 62, and the fourth inclined ventilation passage 64 are each located at points where the wearer is prone to sweating (sweating points). Specifically, the vertical ventilation passage 60 is positioned along the wearer's centerline CL. The second inclined ventilation passage 62 is positioned below and adjacent to the scapula 93. The fourth inclined ventilation passage 64 is positioned corresponding to the waistline 92.

[0066] The upper garment 1 according to this embodiment provides the following effects.

[0067] The upper garment 1 comprises a back panel 3 that covers the back of the wearer 9, and one or more protrusions 5 that project inward from the back panel 3 and have a predetermined compressibility that maintains a space for air to flow between the back panel 3 and the wearer 9.

[0068] According to this configuration, for example, when a backpack is worn, the protrusion 5 is compressed by the load of the backpack, but the protrusion 5 has a predetermined compression ratio that resists crushing deformation. Therefore, even after compression, the protrusion 5 does not completely crush and deform, and the protrusion 5 can maintain the desired height, thus maintaining a ventilation space for air to flow between the back panel 3 and the wearer 9. As a result, even when a backpack is worn, stuffiness that may occur between the back panel 3 and the wearer 9 is easily eliminated.

[0069] The protrusion 5 has a predetermined protrusion amount H1 that extends from the back body 3 toward the inner surface.

[0070] With this configuration, since the protrusion 5 has a desired protrusion amount H1, for example, when a backpack is worn, the desired protrusion amount can be maintained even after the protrusion 5 is crushed and deformed. As a result, a ventilation space is maintained between the back body 3 and the wearer 9, which helps to eliminate stuffiness that may occur between the back body 3 and the wearer 9.

[0071] The compressibility of the protrusion 5 is the ratio of the deformation allowance ΔH of the protrusion 5 after deformation to the amount of protrusion H1 of the protrusion 5 before deformation, when a load of 7 kg is applied to the entire protrusion 5 of one or more protrusions 5, and the compressibility of the protrusion 5 is 62% or less.

[0072] With this configuration, the compression ratio of the protrusion 5 is 62% or less, so the protrusion 5 is less likely to collapse, and it is easier to maintain space for air to flow between the back panel 3 and the wearer 9 when the backpack is worn. If the compression ratio of the protrusion 5 exceeds 62%, the protrusion 5 is more likely to collapse, and it is difficult to prevent the protrusion 5 from collapsing when the backpack is worn.

[0073] The compression ratio of the aforementioned protrusion is 33% or more.

[0074] According to this configuration, if the compression ratio of the protrusion 5 is less than 33%, a foreign body sensation is likely to occur on the back, and comfort is likely to be impaired.

[0075] The protrusion amount H1 of the convex portion 5 is between 5 mm and 13 mm.

[0076] According to this configuration, if the protrusion amount H1 of the convex part 5 is less than 5 mm, the convex part 5 is prone to collapsing, and it is difficult to prevent the convex part 5 from collapsing when wearing a backpack. If the protrusion amount H1 of the convex part 5 exceeds 13 mm, a feeling of foreignness is likely to occur on the back, and comfort is likely to be impaired.

[0077] The protrusion 5 (third protrusion 53) is positioned at least on the lower part of the wearer's scapula 93.

[0078] With this configuration, if the protrusion 5 is positioned on the scapula 93, interference between the scapula 93 and the protrusion 5 is likely to occur, causing discomfort. However, by positioning it adjacent to the lower part of the scapula 93, discomfort can be suppressed.

[0079] The protrusion 5 has multiple protrusions 5, and the distances W1, W2, W3, W4 between adjacent protrusions 5 are between 45 mm and 145 mm.

[0080] With this configuration, if the distance between the protrusions 5 is less than 45 mm, the air passage for ventilation tends to become narrow. If it exceeds 145 mm, the back panel 3 is likely to come into contact with the wearer 9 between the protrusions 5, and the air passage for ventilation may disappear.

[0081] The protrusion 5 is a long member, positioned opposite each other across the widthwise center line CL of the back panel 3, and inclined upward from the outside in the width direction toward the center.

[0082] With this configuration, the convex portion 5 is inclined upward from the outside in the width direction toward the center, which makes it easier for air between the back body 3 and the wearer 9 to be guided upward.

[0083] The back panel 3 has a ventilation section 7 located in the center in the width direction and below the neckline 3a.

[0084] With this configuration, the air guided upward between the protrusions 5 of the back panel 3 is easily ventilated.

[0085] The upper garment 1 can be worn in combination with a middle layer 8 worn on the inner surface side of the upper garment 1. The middle layer 8 includes thermal insulation packs 85, 86, and 87 with filling material. When the upper garment 1 and the middle layer 8 are worn together, the protrusion 5 is positioned so as not to overlap with the thermal insulation packs 85, 86, and 87.

[0086] With this configuration, interference between the thermal packs 85, 86, and 87 of the middle layer 8 and the protrusions 5 of the upper garment 1 can be prevented, thus reducing discomfort for the wearer.

[0087] [Measurement Test 1] In Measurement Test 1, the temperature and humidity inside the garments of the Example and Comparative Example were measured while they were being worn. The results of these Measurement Test 1 are shown in Figures 6 and 7. The Comparative Example is a long-sleeved outer garment without any protrusions. The Example is a long-sleeved outer garment equipped with the protrusions 5 and ventilation parts 7 described in this embodiment. The only difference between the Comparative Example and the Example is the presence or absence of the protrusions 5 and ventilation parts 7.

[0088] As shown in Figure 5, in measurement test 1, subject P1 wore underwear P2, a middle layer P3, and outerwear P4 in that order, and performed exercise while carrying a backpack P5 (7 kg). The test environment was 13°C and 60% RH.

[0089] The exercise consisted of 10 minutes of rest, 30 minutes of stepping exercise (at a tempo of 80 bpm: stepping up and down at 0.75-second intervals), 3 minutes of rest, 5 minutes of maintaining a crouching posture (changing posture every 3.75 seconds (alternating between standing and sliding postures)), 3 minutes of rest, 30 minutes of stepping exercise, 3 minutes of rest, and 5 minutes of maintaining a crouching posture.

[0090] Next, we will describe the method for measuring temperature and humidity in the inner and outer layers of the garment. In Measurement Test 1, temperature and humidity sensors were placed on the upper and lower back of the skin on the back of subject P1 to measure the temperature and humidity between the skin (inner layer) and the undergarment. Temperature and humidity sensors were placed on the upper and lower middle back of the middle layer to measure the temperature and humidity between the middle layer (outer layer) and the outergarment.

[0091] The upper back and middle upper back correspond to the center of the subject P1's back and the area below the neck; in other words, the upper back and middle upper back correspond to the ventilation portion 7 of the garment 1. The lower back and middle lower back correspond to the center of the subject P1's back and the height of the armpit point 91; in other words, the lower back and middle lower back correspond to the upper end of the first protrusion 51 of the garment 1.

[0092] Figure 6(a) is a graph showing the temperature of the inner layer (between skin and underwear) of the Example and Comparative Example during the first step-up exercise (25 minutes after the start of exercise) and just before the end of the second step-up exercise (80 minutes after the start of exercise). Figure 6(b) is a graph showing the temperature of the outer layer (between the middle layer and outerwear) of the Example and Comparative Example during the first step-up exercise (25 minutes after the start of exercise) and just before the end of the second step-up exercise (80 minutes after the start of exercise). The inner layer temperature of the Example and Comparative Example is the average value of the measurements from the temperature sensors on the upper and lower back. The outer layer temperature of the Example and Comparative Example is the average value of the measurements from the temperature sensors on the upper and lower back of the middle layer.

[0093] Figure 7 is a graph showing the humidity of the inner and outer layers of the Example and Comparative Example at the end of the second lifting motion. The humidity of the inner layer of each Example and Comparative Example is the average value of the measurements from the humidity sensors at the upper and lower back. The humidity of the outer layer of each Example and Comparative Example is the average value of the measurements from the humidity sensors at the upper and lower middle back.

[0094] As shown in Figure 6, the temperature of the example tended to be higher than that of the comparative example for both the inner and outer layers. In particular, the temperature of the example tended to be higher than that of the comparative example for the outer layer.

[0095] As shown in Figure 7, regarding humidity, both the inner and outer layers of the example showed lower humidity compared to the comparative example. Specifically, the humidity of the inner layer of the example decreased by 33% and the humidity of the outer layer decreased by 23% compared to the comparative example. From the above, it was found that the humidity inside the garment is reduced during the latter half of exercise, when the temperature inside the garment tends to rise and stuffiness is likely to occur, and that the ventilation effect inside the garment is obtained by the protrusions 5 and ventilation parts 7. In other words, the results showed that the ventilation function inside the garment can be maintained even when the wearer is carrying a backpack. For example, in situations where heat retention is required, such as Nordic skiing, it is possible to suppress chills from sweat by raising the temperature inside the garment while maintaining the ventilation effect.

[0096] In this embodiment, the protrusion 5 has been described as having a solid core material 5a, but it is not limited to this, and as shown in the first modified example of the protrusion 105 in Figure 8, the protrusion 105 may have a hollow core material 105a.

[0097] This configuration allows for the formation of an air passage for ventilation within the hollow space S of the protrusion 105. Since it is not filled with foam or other materials, it can be made lighter compared to when the protrusion is made of a solid material.

[0098] In this embodiment, an example has been described in which the ventilation section 7 is composed of a vent 71 such as a punching hole, but it is not limited to this. As shown in Figure 9, the ventilation section 107 may be composed of a hollow columnar member 107 that is located below the neckline 3a of the back body 3, on the center line CL, and is open to the neckline 3a. With this configuration, the hollow space 171 of the columnar member 107 can expel the air inside the top 1 to the outside.

[0099] In this embodiment, an example in which the protrusion 5 is composed of a long member has been described, but it is not limited to this, and as in the second modified example of the protrusion 205 shown in Figure 10, the first to sixth protrusions 251, 252, 253, 254, 255, and 256 constituting the protrusion 205 may be a group of protrusions composed of multiple protrusions 251a, 252a, 253a, 254a, 255a, and 256a. Each protrusion 251a, 252a, 253a, 254a, 255a, and 256a is, for example, hexagonal in plan view. With this configuration, compared to the case in which each protrusion is square in plan view, the number of ridges extending in the thickness direction (inner surface side) of the upper garment 1 can be increased, so compressive deformation of each protrusion is more easily suppressed.

[0100] As shown in Figure 11, the protrusion 205 in Figure 10 may be formed by embossing Flexknit®, a composite material manufactured by Nishikawa Rose Co., Ltd., which combines nonwoven fabric and warp knitting. Embossing is possible by mixing formable fibers, such as polyester, into the nonwoven fabric that makes up Flexknit®. The protrusion amount H11 of the protrusion 205 using Flexknit is 7.5 mm. When Flexknit is used, there is no need to bond it with other equipment, and deep drawing can be performed with a simple structure.

[0101] In this embodiment, a configuration comprising the first to sixth protrusions 51, 52, 53, 54, 55, and 56 has been described, but the embodiment is not limited to this, and at least one of the first to sixth protrusions 51, 52, 53, 54, 55, and 56 may be provided, or a combination of multiple protrusions may be provided.

[0102] [Measurement Test 2] In Measurement Test 2, the humidity inside the garments during wear was measured for Comparative Example 1 and Examples 1-4. The results of these Measurement Tests 2 are shown in Figure 14. Comparative Example 1 is a long-sleeved outer garment without any protrusions. Example 1 is a long-sleeved outer garment equipped with the protrusions 5 and ventilation section 7 described in this embodiment. Example 2 is a long-sleeved outer garment 301 equipped with the third protrusion 353, the fourth protrusion 354, and the ventilation section 7 of the protrusions 5 described in this embodiment, as shown in Figure 12. Example 3 is an outer garment equipped with the ventilation section 7, in addition to the protrusions 405 being composed of a group of protrusions 453a provided in the portion corresponding to the third protrusion 453, as shown in Figure 13. Example 4 is an outer garment equipped with the third protrusion 353, the fourth protrusion 354, and the ventilation section 7 shown in Figure 12, as well as an opening 307a extending in the width direction, as shown by the thick dashed line in Figure 12. Comparative Example 1 and Examples 1-4 differ in the presence or absence of the protrusion 5 and ventilation section 7. Examples 1-3 differ in the configuration of the protrusion 5. Example 4 has the same structure as Example 2 for the protrusion, but differs in the structure of the ventilation section 7. In addition, Comparative Example 1 and Examples 1-4 of the outerwear may have a so-called yoke section (a portion extending in the width direction from the neckline to the armhole). In this case, the ventilation section and opening provided on the back of the garment are covered from the outer surface by the yoke section. Therefore, the appearance is not spoiled by the ventilation section and opening.

[0103] In Measurement Test 2, sweating thermal mannequins were dressed in the outerwear of Comparative Example 1 and Examples 1-3, respectively, and performed exercises while carrying a backpack (7 kg). The test environment was 15°C and 50% RH. The exercise consisted of 5 minutes of standing rest and 20 minutes of arm swinging (90 Hz). During arm swinging, 50 g / m 2 The experiment was conducted by using a sweating mannequin to induce sweating at / h.

[0104] Next, we will describe the method for measuring temperature and humidity. In measurement test 2, a temperature sensor and a humidity sensor were placed on the back of the sweating mannequin to measure the temperature and humidity between the mannequin's skin and each piece of outerwear.

[0105] As shown in Figure 14, regarding humidity, the results showed that the humidity in Examples 1 to 4 was lower than that in Comparative Example 1. Specifically, compared to Comparative Example 1, the humidity inside the garment in Example 1 decreased by 21%, in Example 2 by 16%, in Example 3 by 15%, and in Example 4 by 20%. From the above, it was found that even when only the third protrusion 353 and the fourth protrusion 354 are provided among the first to sixth protrusions 51, 52, 53, 54, 55, and 56, as in Example 2, a ventilation effect can be obtained. Furthermore, it was found that even when the protrusion 405 is provided as a group of protrusions 453a in the part corresponding to the third protrusion, as in Example 3, a ventilation effect equivalent to that of Example 2 can be obtained. In addition, it was found that by providing the opening 307a in addition to the third protrusion 353 and the fourth protrusion 354 and the ventilation unit 7, as in Example 4, a ventilation effect equivalent to that of Example 1 can be obtained.

[0106] In this embodiment, an example in which the garment is applied to outerwear has been described, but it is not limited to this, and for example, it may be applied to upper garments such as a T-shirt 501 or a shirt, as shown in Figure 15. The T-shirt 501 in Figure 15 is shown in an inside-out state, and the third protrusion 553 and the fourth protrusion 554 are fixed by hot melt or the like so as to protrude to the inner surface side of the back body 503.

[0107] Furthermore, the garment of the present invention is not limited to the configuration of the embodiments described above, and various modifications are possible.
