[0004] [Patent Document 1] Patent No. 6618889 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the inventors have found through their research that there is room for improvement in the comfort of shirts of the prior art around the shoulders of the wearer. Specifically, a wearer wearing a shirt of the prior art may feel a tightness around the shoulders of the shirt. Furthermore, such a tightness may cause fatigue in the wearer. Thus, there is room for improvement in the parts of shirts of the prior art that come into contact with the shoulders of the wearer.

[0006] In view of the above circumstances, an object of the present invention is to provide a comfortable shirt that reduces the feeling of tightness around the shoulders of the wearer. [Means for solving the problem]

[0007] The inventors discovered that the above problem could be solved by inclining the lower edge of the yoke and the upper edge of the back body at a predetermined angle from the center toward both ends, and thus completed the present invention.

[0008] That is, the shirt according to the present invention is A shirt having a yoke and a back panel, The yoke has a lower edge that is a joining edge with the back body, The back body has an upper edge that is a joining edge with the yoke, Each of the lower edge and the upper edge is inclined downward from the center toward both ends, When a first straight line connecting the center of the lower edge and the tip and a second straight line connecting the center of the upper edge and the tip are drawn, a first inclination angle of the first straight line relative to the width direction of the shirt is 5 to 16 degrees; A second inclination angle of the second straight line with respect to the width direction is 3 to 12 degrees larger than the first inclination angle.

[0009] According to this configuration, the first inclination angle is 5 to 16° and the second inclination angle is 3 to 12° larger than the first inclination angle, thereby reducing the feeling of tightness around the shoulders of the wearer, making the garment more comfortable to wear.

[0010] The shirt according to the present invention preferably comprises: The lower edge and the upper edge are each formed in a curved shape that bulges upward.

[0011] According to this configuration, the lower edge and the upper edge are each formed in a curved shape that bulges upward, which further reduces the feeling of tightness around the shoulders of the wearer, making the garment even more comfortable to wear. [Effects of the Invention]

[0014] Hereinafter, a shirt according to one embodiment of the present invention will be described with reference to the drawings, taking a dress shirt as an example.

[0015] As shown in FIGS. 1 and 2, the shirt 1 according to this embodiment includes a front body 10 covering the front side of the wearer, a back body 20 covering the back side of the wearer, a yoke 30 covering the shoulders of the wearer, a collar 40 arranged around the neck of the wearer, and a pair of sleeves 50 covering the arms of the wearer. The shirt 1 also includes a joint 60 formed by joining the various parts. The joint 60 in this embodiment is formed by stitching with thread. The left-right direction when viewing the shirt 1 from the front or back side may be referred to as the width direction, and the direction perpendicular to the width direction as the up-down direction. FIGS. 3 to 6 show the state (separated state) before the fabric pieces constituting the above-mentioned parts are joined.

[0016] As shown in FIG. 1, the front body 10 has an upper front body 11 having a plurality of buttonholes formed therein, and a lower front body 12 having a plurality of buttons that can be engaged with the respective buttonholes.

[0017] 3, the upper front body 11 has an armhole forming edge 112 that forms the armhole of the shirt 1, and an upper front body side edge 113 that serves as a joining edge with the back body 20. In this embodiment, the upper front body side edge 113 is formed so as to curve inward in the width direction.

[0018] Similarly, the lower front body 12 has an armhole forming edge 122 that forms the armhole of the shirt 1, and a lower front body side edge 123 that serves as the joining edge with the back body 20. In this embodiment, the lower front body side edge 123 is formed so as to curve inward in the width direction of the shirt 1.

[0019] In the front body 10 having such an upper front body 11 and a lower front body 12, hereinafter, a straight line passing through the lower end of the armhole forming edge 112 or the armhole forming edge 122 (in other words, the upper end of the upper front body side edge 113 or the lower front body side edge 123) and extending in the width direction will be referred to as the front body bust line BLf, a straight line passing through the most inward point in the width direction of the upper front body side edge 113 or the lower front body side edge 123 and extending in the width direction will be referred to as the front body waist line WLf, and a straight line passing through the lower end of the upper front body side edge 113 or the lower front body side edge 123 and extending in the width direction will be referred to as the front body hip line HLf.

[0020] The front body 10 is preferably formed so that its width decreases from the front body bust line BLf toward the front body waist line WLf. This improves the appearance of the wearer. In addition, it can reduce the feeling of tightness around the chest of a wearer with a body type such as a B-type, whose chest circumference is larger than its waist circumference. Furthermore, the front body 10 is preferably formed so that its width increases from the front body waist line WLf toward the front body hip line HLf. This creates a constricted shape around the wearer's abdomen, improving the appearance of the wearer.

[0021] The upper front body 11 further has an upper left edge 111, which is the joining edge with the yoke 30. In this embodiment, the upper left edge 111 is formed so as to slope downward from the center toward the side edge in the width direction of the shirt 1. It is preferable that the upper left edge 111 is formed in a curved shape that bulges upward.

[0022] The lower front body 12 further has an upper right edge 121, which is the joining edge with the yoke 30. In this embodiment, the upper right edge 121 is formed so as to slope downward from the center toward the side edge in the width direction of the shirt 1. It is preferable that the upper right edge 121 is formed in a curved shape that bulges upward.

[0023] As shown in FIG. 4, the back body piece 20 has an upper edge 21 that is the joining edge with the yoke 30. In this embodiment, the upper edge 21 is formed so as to slope downward from its center toward both ends. The upper edge 21 is preferably formed in a curved shape that bulges upward. More preferably, the upper edge 21 has a straight portion 211 that extends from its center in the width direction of the shirt 1, and a pair of curved portions 212 that extend from both ends of the straight portion 211 so as to slope downward.

[0024] The ratio of the length of straight portion 211 to the length of line segment LS1 drawn by connecting both ends of upper edge 21 is preferably 0.1 to 0.16, and more preferably 0.04 to 0.10. Since the length of line segment LS1 is usually 40 to 60 cm, the length of straight portion 211 is preferably 4.0 to 9.6 cm, and more preferably 1.6 to 6.0 cm.

[0025] The back body 20 has armhole forming edges 22 that form the armholes of the shirt 1, and back body side edges 23 that serve as joining edges with the front body 10. In this embodiment, each of the back body side edges 23 is formed to curve inward in the width direction of the shirt 1.

[0026] In the following description of such a back body 20, the straight line passing through the lower end of the armhole-forming edge 22 (in other words, the upper end of the back body side edge 23) and extending in the width direction of the shirt 1 will be referred to as the back body bust line BLb, the straight line passing through the most inward point in the width direction of the back body side edge 23 and extending in the width direction of the shirt 1 will be referred to as the back body waist line WLb, and the straight line passing through the lower end of the back body side edge 23 and extending in the width direction of the shirt 1 will be referred to as the back body hip line HLb.

[0027] The back body section 20 is preferably formed so that its width decreases from the back body bust line BLb toward the back body waist line WLb. This improves the appearance of the wearer. In addition, it can further reduce the feeling of tightness around the chest of a wearer with a body type such as a B-type whose chest circumference is larger than its waist circumference. Furthermore, the back body section 20 is preferably formed so that its width increases from the front body waist line WLb toward the back body hip line HLb. This creates a constricted shape around the wearer's abdomen, further improving the appearance of the wearer.

[0028] The back body 20 of this embodiment is formed with a pair of darts 24 extending in the vertical direction. In this embodiment, the darts 24 are formed in a vertically elongated diamond shape extending between the back body bustline BLb and the back body hipline HLb. Each dart 24 is formed so that its widest portion overlaps the back body waistline WLb. Furthermore, each dart 24 is preferably formed below the curved portion 212 at the upper edge 21 of the back body 20. This makes it easier for the darts 24 to align in the vertical direction with the portions of the back body 20 that may protrude backward due to the wearer's shoulder blades, thereby suppressing the occurrence of wrinkles.

[0029] As shown in Figures 1 and 4, the yoke 30 has a pair of front lower edges 31 that become the joining edges with the front body 10 when made into the shirt 1, a back lower edge 32 that becomes the joining edge with the back body 20, a neck edge 33 that is formed to connect the front lower edges 31 and is placed around the neck of the wearer, and a pair of yoke side edges 34 that form the armholes of the shirt 1.

[0030] The front lower edges 31 are joined to the left upper edge 111 and the right upper edge 121 of the front body 10, respectively. This gives the shirt 1 a pair of front yoke joining portions 61 where the front body 10 and the yoke 30 are joined. In this embodiment, the front lower edges 31 are formed in a curved shape that bulges upward when joined to form the shirt 1.

[0031] 2 and 4, the back lower edge 32 is joined to the top edge 21 of the back body 20. This gives the shirt 1 a back yoke joining portion 62, which is the portion where the back body 20 and the yoke 30 are joined.

[0032] The back lower edge 32 is formed so as to slope downward from its center toward both ends. In this embodiment, the back lower edge 32 is formed in a curved shape that bulges upward when made into the shirt 1. The back lower edge 32 preferably has a straight portion 321 extending from its center in the width direction of the shirt 1, and a pair of curved portions 322 extending at an angle downward from both ends of the straight portion 321. The straight portion 321 is joined to the straight portion 211 of the back body piece 20. The curved portions 322 are joined to the curved portions 212 of the back body piece 20.

[0033] The ratio of the length of the straight line portion 321 to the length of the line segment LS2 drawn by connecting both ends of the rear lower edge 32 is preferably 0.1 to 0.16, and more preferably 0.04 to 0.10. Since the length of the line segment LS2 is usually 40 to 60 cm, the length of the straight line portion 321 is preferably 4.0 to 9.6 cm, and more preferably 1.6 to 6.0 cm.

[0034] Each of the yoke side edges 34 is joined to an armhole-forming edge of the sleeve portion 50. As a result, the shirt 1 has a sleeve joining portion 63 where the yoke 30 and the sleeve portion 50 are joined.

[0035] In this embodiment, each of the yoke-side edges 34 is formed to curve inward in the width direction of the shirt 1. Furthermore, the front end of each of the yoke-side edges 34, which is the end joined to the front body 10, is positioned outward in the width direction than the back end, which is the end joined to the back body 20.

[0036] 5, in the above-described yoke 30, a straight line passing through the center of the neck edge 33 and extending in the width direction of the shirt 1 will hereinafter be referred to as the front reference line Lf, and a straight line passing through the center of the lower back edge 32 and extending in the width direction of the shirt 1 will hereinafter be referred to as the back reference line Lb. Such a yoke 30 has a pair of front extension regions 35 extending downward from the front reference line Lf on the front side of the shirt 1, and a pair of rear extension regions 36 extending downward from the back reference line Lb on the back side of the shirt 1.

[0037] Each of the forward extending regions 35 is formed to extend outward in the width direction, which allows the yoke 30 to easily conform to the shape of the wearer's shoulders, reducing the feeling of tightness around the shoulders and reducing the occurrence of wrinkles.

[0038] Each of the rear extension regions 36 is formed to extend outward in the width direction, which allows the yoke 30 to more easily conform to the shape of the wearer's shoulders, reducing the feeling of tightness around the shoulders and reducing the occurrence of wrinkles.

[0039] The distance between the front reference line Lf and the rear reference line Lb is preferably 5 to 10 cm.

[0040] Furthermore, as shown in Figure 6, in order to reduce the feeling of tightness around the shoulders of the wearer, it is important that the upper edge 21 of the back body 20 and the lower rear edge 32 of the yoke 30 have a predetermined relationship in their inclination angles relative to the width direction.

[0041] Specifically, first, a first straight line L1 is drawn connecting the center and tip of the lower back edge 32, and a second straight line L2 is drawn connecting the center and tip of the upper edge 21. It is important that the first inclination angle θ1, which is the angle at which the first straight line L1 slopes downward relative to the width direction of the shirt 1, is 5 to 16 degrees, and that the second inclination angle θ2, which is the angle at which the second straight line L2 slopes downward, is 3 to 12 degrees greater than the first inclination angle θ1. More preferably, the first inclination angle θ1 is 5 to 10 degrees, and the second inclination angle θ2 is 3 to 12 degrees greater than the first inclination angle θ1. Even more preferably, the first inclination angle θ1 is 7 to 10 degrees, and the second inclination angle θ2 is 5 to 8 degrees greater than the first inclination angle θ1. This reduces the feeling of tightness around the shoulders of the wearer, making the shirt 1 more comfortable to wear.

[0042] Furthermore, by making the difference between the second inclination angle θ2 and the first inclination angle θ1 12° or less, the rear yoke joint 62 formed by the upper edge 21 of the back body 20 and the rear lower edge 32 of the yoke 30 does not bulge outward (as if a dart were formed), but rather has a natural shape that follows a curved surface, which is preferable.

[0043] The first inclination angle θ1 is preferably 16° or less so that the yoke 30 of the shirt 1 can easily fit around the shoulders of the wearer. The second inclination angle θ2 is preferably 25° or less, and more preferably 22° or less so that the area around the back yoke joint 62 formed by the upper edge 21 of the back body 20 and the lower rear edge 32 of the yoke 30 can easily fit around the shoulders of the wearer.

[0044] As shown in FIG. 7 , because the second inclination angle θ2 is greater than the first inclination angle θ1, when a part of the back yoke joint 62 is formed by joining the straight portion 211 at the top edge 21 of the back body 20 and the straight portion 321 at the rear lower edge 32 of the yoke 30, a gap G is formed between the curved portion 212 at the top edge 21 and the curved portion 322 at the rear lower edge 32. This results in the periphery of the joint formed by the rear lower edge 32 of the yoke 30 and the top edge 21 of the back body 20 having a three-dimensional shape that bulges outward from the shirt 1, reducing tightness around the shoulders of the wearer and improving the comfort of the shirt 1. Furthermore, the occurrence of wrinkles in the back body 20 caused by the wearer's shoulder blades coming into contact with the back body 20 is suppressed, improving the appearance of the wearer.

[0045] Although the embodiments have been shown as examples, the shirt of the present invention is not limited to the configuration of the above-described embodiments. Furthermore, the shirt of the present invention is not limited by the above-described effects. The shirt of the present invention can be modified in various ways without departing from the spirit and scope of the present invention.

[0046] For example, the shirt in the above embodiment is a dress shirt, but is not limited to this and may be a casual shirt. [Example]

[0047] The present invention will be explained in more detail below with reference to examples, but the present invention is not limited to these examples.

[0048] Simulations using 3D CAD software from Yuka & Alpha were used to evaluate the tightness felt around the shoulders of the wearer and the occurrence of wrinkles in the shirt. Specifically, the fabric used was a 60-count, 100% cotton Oxford (non-shrinkable, two-strand plain weave). For shirts with an upper front body, a lower front body, a yoke, and a back body as shown in Figures 3 to 6, several shirts were designed with various values ​​for the first inclination angle θ1 relative to the lower back edge of the yoke and the second inclination angle θ2 relative to the upper back edge. Each shirt was fitted to a Japanese subject of average build. The shapes of the lower back edge of the yoke and the upper back edge were designed to be curved and bulged upward when the shirt was made.

[0049] [Evaluation of tightness around the shoulders] As shown in Figure 8, the fitted fabric was divided into equilateral triangular regions with sides measuring 2 cm, and the elongation rate of each region was observed. Regions with no stretch in the fabric were designated as regions with a stretch rate of 100%, and regions with a stretch rate of 101% or more were designated as compression regions. The fewer the compression regions, the less restrictive the shirt felt around the shoulders. The results are shown in Table 1 below. (Evaluation criteria for cramped feeling) In this example, shirts with a number of pressure areas less than 150 were evaluated as good shirts. More specifically, shirts with a sufficiently reduced number of pressure areas compared to shirt No. 1 (200 pressure areas), which had no difference between the first inclination angle θ1 in the yoke and the second inclination angle θ2 in the back body, were evaluated as good shirts.

[0050] [Evaluation of wrinkles on the yoke and back] The number of wrinkles on the yoke and back body was counted and evaluated according to the following criteria. The results are shown in Table 1 below. (Wrinkle evaluation criteria) ◯: The number of wrinkles is less than 3. △: The number of wrinkles is 4 to 10. ×: The number of wrinkles is more than 10.

[0051] [Table 1]

[0052] From the results of No. 1 in Table 1, it was found that if the design does not have any difference between the first inclination angle θ1 in the yoke and the second inclination angle θ2 in the back body, the number of pressure areas tends to increase and the feeling of tightness around the wearer's shoulders tends to become greater.

[0053] On the other hand, the results of No. 2 to No. 17 in Table 2 show that by designing the second inclination angle θ2 to be larger than the first inclination angle θ1, the number of pressure areas is reduced and the feeling of tightness around the wearer's shoulders is alleviated.

[0054] More specifically, comparing shirts No. 2 and 3 with θ1 = 4° and shirts No. 4 to 7 with θ1 = 5°, it was found that the shirts with θ1 = 5° had a significantly smaller pressure area. From these results, it can be concluded that the first inclination angle θ1 of the yoke is preferably 5° or greater.

[0055] Furthermore, in both shirts Nos. 4 to 6 with θ1 = 5° and shirts Nos. 7 to 13 with θ1 = 9.5°, the number of pressure zones tended to decrease as [θ2 - θ1] increased toward 6.5° and as [θ2 - θ1] decreased toward 6.5°. This tendency is thought to be similar for shirts Nos. 14 to 16 with θ1 = 16°. From these results, it can be concluded that the second inclination angle θ2 of the back body is preferably 3 to 12° larger than the first inclination angle θ1, and more preferably 3 to 11° larger.

[0056] For shirts with θ1≦17°, specific evaluation was not performed because it was thought that the number of pressure areas was likely to be 150 or more based on the results in Table 1 (especially Nos. 15 to 17). In other words, it can be seen from the results of Nos. 15 to 17 that the first inclination angle θ1 of the yoke is preferably 16° or less.

[0057] In shirt No. 7, where [θ2-θ1]=11°, some bulging was observed along the rear yoke joint, but this was evaluated as not problematic for practical use. [Explanation of symbols]
