Mode for Carrying Out the Invention
[0011] The present invention relates to a swimsuit. Prior to the description of the configuration of this swimsuit 1, while referring to FIG. 1, an overview of the relationship between the swimsuit 1 and the wearer 9 during wearing will be described.
[0012] As a result of intensive research, the inventors obtained the knowledge that competitive swimmers can efficiently exert propulsion force by kicking with the hip joint in an internally rotated state. FIG. 1 is a front view of the swimsuit 1 according to an embodiment of the present invention before being twisted. The swimsuit 1 shown in FIG. 1 is worn by the wearer 9 by twisting the hem 22 toward the inside of the thigh 91 of the wearer 9 (arrow A). As a result, a twisting force is generated in the direction from the waist 92 to the thigh 91 of the wearer 9, and a support force is applied in a state where the hip joint 93 (see FIG. 6) is internal rotation rotated, so that the posture of the wearer 9 is controlled. internal rotation rotated, so that the posture of the wearer 9 is controlled.
[0013] Hereinafter, a spats-type competitive swimming swimsuit (hereinafter also referred to as "swimsuit") 1 which is an embodiment of the swimsuit according to the present invention will be described with reference to the drawings. Hereinafter, based on the state where the wearer 9 wearing the swimsuit 1 stands upright, the up and down, left and right, and front and back of the swimsuit 1 are defined. Also, with respect to the cross-section (thickness direction) of the fabric, the direction from the outer surface toward the inside (wearer side) with respect to the wearer 9 is defined as the inner side, the opposite is the outer side, the direction toward the outer side in the body width direction is defined as the outer side, and the direction toward the center side in the body width direction is defined as the inner side.
[0014] Referring to Figures 1-3, the swimsuit 1 includes a main body 2 that covers at least the area near the waist 92 and part of the lower body, an anti-slip member 4 attached to the inner surface of the main body 2 to improve the adhesion and fit of the swimsuit 1 to the wearer's skin 9, a tape member 5 attached to the main body 2, and a marker P that guides the amount of twisting of the hem 22.
[0015] Referring to Figure 1, the main body 2 is made of an elastic fabric and has a predetermined compression. The elastic fabric is intended to be stretched to 5.9% or more and 30.5% or less, and worn in a close fit to the wearer 9. The stretch rate of the elastic fabric may be calculated, for example, from the circumference of the hem 22 in the pattern and the circumference of the hem when it is worn on a mannequin. The first elastic fabric, which is located on the front side of the wearer and corresponds to the fabric covering the thighs 91, more specifically, a test piece cut from the area shown as a in Figure 1, preferably has an elongation stress of 5.12N or more and 19.7N or less when stretched by 30% in the length (warp) direction, and in this embodiment, for example, it is 7.5N. The first elastic fabric preferably has an elongation stress of 4.65N or more and 11.0N or less when stretched by 30% in the width (weft) direction, and in this embodiment, for example, it is 6.5N. In this embodiment, the recovery stress of the first stretchable fabric when stretched by 30% in the length direction is 0.297 N, and the recovery stress when stretched by 30% in the width direction is 1.036 N.
[0016] If the elongation stress of the first stretchable fabric when stretched 30% in the longitudinal direction is less than 5.12N, and / or if the elongation stress of the first stretchable fabric when stretched 30% in the width direction is less than 4.65N, the compression will be weak and it will be difficult to obtain internal rotation support. If the elongation stress of the first stretchable fabric when stretched 30% in the longitudinal direction exceeds 19.7N, and / or if the elongation stress of the first stretchable fabric when stretched 30% in the width direction exceeds 11.0N, the compression will be strong and it will be difficult to twist the hem 22. In addition, the compression will be excessive and may easily hinder the wearer's movements.
[0017] To measure the stress of stretchable fabric during elongation in both the length and width directions, one piece of fabric measuring 50 mm in width and 200 mm in length was prepared for each direction. The pieces were fixed to a tensile testing machine (Shimadzu Corporation: Autograph AGS-X) with grips 65 mm wide at the top and bottom, and a gripping distance of 100 mm. The fabric was stretched at a tensile speed of 200 mm / min, and the stress at which the elongation rate reached 30% was read and defined as the "elongation stress." When the elongation rate reached 100%, the fabric was allowed to recover at a recovery speed of 200 mm / min, and the stress at which the elongation rate during recovery was 30% was read and defined as the "recovery stress."
[0018] The second stretchable fabric, which is located on the back side of the wearer and covers the thigh 91, more specifically, a test piece taken from the area indicated by b in Figure 3, preferably has an elongation stress of 13.7 N or more and 28.0 N or less when stretched by 30% in the body length direction, and in this embodiment, for example, it is 15.6 N. The second stretchable fabric preferably has an elongation stress of 11.6 N or more and 33.1 N or less when stretched by 30% in the body width direction, and in this embodiment, for example, it is 19.0 N. In this embodiment, the recovery stress of the second stretchable fabric when stretched by 30% in the body length direction is 1.54 N, and the recovery stress when stretched by 30% in the body width direction is 1.84 N.
[0019] If the elongation stress of the second stretchable fabric at 30% stretch in the body length direction is less than 13.7N, and / or if the elongation stress of the second stretchable fabric at 30% stretch in the body width direction is less than 11.6N, the compression will be weak and it will be difficult to obtain internal rotation support. If the elongation stress of the second stretchable fabric at 30% stretch in the body length direction exceeds 28.0N, and / or if the elongation stress at 30% stretch in the body width direction exceeds 33.1N, the compression will be strong and it will be difficult to twist the hem 22. In addition, the compression will be excessive and may easily hinder the wearer's movements.
[0020] As shown in Figure 1, the main body 2 has a waist portion 21 located at the waist 92 of the wearer 9, and a pair of left and right hem portions 22, 22 into which the wearer's left and right legs are inserted.
[0021] A strip-shaped anti-slip member 4 is attached to the waist portion 21 and the hem portion 22, respectively. More specifically, the anti-slip member 4 has a waist tape 41 located on the waist portion 21 and a hem tape 42 located on the hem portion 22. The waist tape 41 is adhered to the inner surface of the main body portion 2 along the upper edge of the waist portion 21 over its entire circumference. Note that the waist tape 41 may have portions where it is not provided, for example, if a drawstring for waist adjustment is provided. The hem tapes 42 are adhered to the inner surface of the main body portion 2 along the lower edges of the left and right pair of hem portions 22 over their entire circumference.
[0022] The waist tape 41 and hem tape 42 ensure that the waist portion 21 and each hem portion 22 adhere closely to the wearer's skin, thereby suppressing slippage of the waist portion 21 and hem portion 22 against the wearer's skin. More specifically, if slippage occurs between the waist portion 21, hem portion 22, and the wearer's skin, it becomes difficult to maintain the twisted state of the hem portion 22 relative to the waist portion 21 when the hem portion 22 is twisted for wearing, making it difficult for the internal rotation support force to be applied. In contrast, by suppressing slippage of the waist portion 21 against the waist portion 92, the hem portion 22 can be twisted while the waist portion 21 is fixed, and by suppressing slippage of the hem portion 22 against the thigh portion 91, it becomes easier to fix the hem portion 22 in a twisted state relative to the waist portion 21.
[0023] The anti-slip member 4 can be made of a material with a coefficient of friction such that slippage does not occur between the wearer 9 and the anti-slip member 4. For example, a silicone-coated tape can be used. In this embodiment, the waist tape 41 is made of a silicone-coated tape with a width of 20 mm, and the hem tape 42 is made of a silicone-coated tape with a width of 10 mm to 20 mm.
[0024] As shown in Figures 1-3, the main body 2 has a front body fabric 31 that covers the abdominal side of the wearer 9 and a back body fabric 32 that covers the buttocks side of the wearer.
[0025] In this embodiment, the main body 2 has a front body fabric 31 and a back body fabric 32 connected by a pair of left and right side seams 24 on both sides in the width direction, a pair of left and right inseam seams 25 connected on the inside in the width direction, and a crotch portion 23 connected between the pair of left and right inseam seams 25. The crotch portion 23 is located in the crotch area of the wearer 9, the side seams 24 extend vertically from the waist portion 21 to the hem portion 22 on the outside in the width direction, and each inseam seam 25 extends vertically from the left and right ends of the crotch portion 23 to the hem portion 22.
[0026] Figures 4 and 5 are front and back views of the swimsuit 1 when turned inside out. As shown in Figures 1 to 5, the front body fabric 31 and the back body fabric 32 each have an outer fabric 33 located on the outside in the thickness direction of the fabric cross-section and a lining fabric 34 located on the inside in the thickness direction of the outer fabric 33. In this embodiment, the outer fabric 33 and the lining fabric 34 are each composed of multiple fabrics.
[0027] As shown in Figures 1 to 3, the outer fabric 33 has an outer front fabric 33a that constitutes the front body fabric 31 and an outer back fabric 33b that constitutes the back body fabric 32. The outer front fabric 33a has an outer center fabric 33c that is positioned to correspond to the wearer's abdomen, and an outer left front fabric 33d and an outer right front fabric 33e that are positioned to the left and right sides of the wearer, respectively, with the outer center fabric 33c in between. The outer back fabric 33b has an outer left back fabric 33f that is located on the left side in the width direction, Located on the right side in the width direction The front right rear portion has a weight of 33g.
[0028] As shown in Figures 4 and 5, the lining fabric 34 has a front lining fabric 34a that constitutes the front bodice fabric 31 and a back lining fabric 34b that constitutes the back bodice fabric 32. The front lining fabric 34a has a shape corresponding to the front center fabric 33c and is attached to the inside of the front center fabric 33c. The back lining fabric 34b has a shape corresponding to the front left back fabric 33f and the front right back fabric 33g and has a left back lining fabric 34c and a right back lining fabric 34d that are attached to the inside of the front left back fabric 33f and the front right back fabric 33g. In other words, the lining fabric 34 is not attached to the inside of the front left front fabric 33d and the front right front fabric 33e.
[0029] The left rear lining fabric 34c and the right rear lining fabric 34d have a first rear lining fabric 34e, 34f located on the outside in the width direction, a second rear lining fabric 34g, 34h located on the inside and upper side in the width direction, and a third rear lining fabric 34i, 34j located on the inside and lower side in the width direction.
[0030] Thus, the main body 2 is formed by sewing or joining multiple outer fabrics 33 and inner fabrics 34. Tape members 5 are attached to the parts where the ends of the multiple outer fabrics 33 and inner fabrics 34 are sewn or joined together.
[0031] The tape member 5 comprises a pair of left and right side tapes 51 extending along a pair of left and right side seams 24, a crotch tape 52 extending along an inner thigh seam 25, and a pair of left and right back tapes 53 provided on the back body fabric 32. The longitudinal tensile stress of the tape member 5 is greater than that of the first and second stretchable fabrics that constitute the main body 2, and the elongation stress of the tape member 5 when stretched to 30% is set to be between 3.0 and 6.7 times that of the first stretchable fabric and between 1.5 and 3.2 times that of the second stretchable fabric.
[0032] As shown in Figures 1 and the left side view of Figure 2, the side tape 51 extends vertically along the side seam 24 on the outer surface of the main body 2. More specifically, the side tape 51 has a first inclined portion 51a that slopes backward downward from the upper edge of the waist portion 21 above the wearer's greater trochanter 94, a second inclined portion 51b that slopes forward further downward from below the greater trochanter 94 and extends to the lower edge of the hem portion 22, and a curved portion 51c that is curved and positioned between the first inclined portion 51a and the second inclined portion 51b so as to wrap around to the rear side of the greater trochanter 94. In other words, the curved portion 51c is provided in the portion corresponding to the greater trochanter 94. In this embodiment, the right side tape 51 has the same configuration as the left side tape 51, so its description is omitted.
[0033] As shown by arrow A in Figure 2, when the hem 22 is twisted and the swimsuit 1 is worn, the side tape 51 is twisted inward in the width direction, starting from the upper end of the first inclined portion 51a. At this time, the curved portion 51c acts as an inward rotation support force on the greater trochanter 94 from rear to front.
[0034] As shown in Figure 7, in this embodiment, the side tape 51 is constructed by laminating power tape (a first tape T2 with a width of 10 mm and a second tape T3 with a width of 10 mm) T1 and a woven or knitted base fabric tape T4 with a width of 20 mm in this order. Hot melt H is placed between these tapes T2, T3, and T4, or between the main body 2 and the tapes. The side tape 51 is heat-pressed onto the joint after joining the outer edge in the width direction of the front body fabric 31 (front left front fabric 33d) and the outer edge in the width direction of the back body fabric 32 (front left back fabric 33f and first back back fabric 34e) with an ultrasonic sewing machine. The front left back fabric 33f and the first back back fabric 34e may be bonded with hot melt H before being joined to the front left front fabric 33d. The recovery stress of the side tape 51 when stretched by 30% is preferably set to 0.5N or more and 10.73N or less, and in this embodiment, for example, it is 3.88N.
[0035] As shown in Figures 1 and 4, the crotch tape 52 extends along the inner thigh seam 25 and the crotch area 23 on the inner side of the main body 2. More specifically, the crotch tape 52 has a right inner thigh tape portion 52a extending along the right inner thigh seam 25a, a left inner thigh tape portion 52b extending along the left inner thigh seam 25b, and a crotch tape portion 52c extending in the width direction along the crotch area 23.
[0036] The right inner thigh tape portion 52a slopes outward in the width direction downward from the right end of the crotch portion 23. The left inner thigh tape portion 52b slopes outward in the width direction downward from the left end of the crotch portion 23. In other words, when the swimsuit 1 is worn without twisting, the lower ends of the right inner thigh tape portion 52a and the left inner thigh tape portion 52b are located on the front side in the circumferential direction of each thigh portion 91, rather than their upper ends, and form an inverted V shape in a front view. At this time, the lower ends of the right inner thigh tape portion 52a and the left inner thigh tape portion 52b are each located on the widthwise central side of the thigh portion 91. The recovery stress when the crotch tape 52 is stretched by 30% is preferably set to 0.159N or more and 7.30N or less, and in this embodiment, for example, it is 1.86N.
[0037] Figure 8 is a schematic diagram showing a magnified view of the area around the crotch portion 23 indicated by arrow VIII in Figure 1, as well as a view from below. Figure 9 shows an end view along the line IX-IX in Figure 8, and Figure 10 shows an end view along the line XX in Figure 8. As shown in Figures 8 to 10, the crotch tape 52 is constructed by laminating a 10 mm wide third tape T5 and a 20 mm wide woven or knitted base fabric tape T6 in this order. These third tapes T5 and base fabric Hot melt H is placed between the tapes T6, or between the main body 2 and the third tape T5.
[0038] As shown in Figures 8 and 9, in the right inner thigh tape portion 52a, the inner rear edge portion in the width direction of the front body fabric 31 (outer right front fabric 33e) and the inner front edge portion in the width direction of the back body fabric 32 (outer back fabric 33b and inner back fabric 34b) are joined together with an ultrasonic sewing machine, and then a third tape T5 and base fabric Tape T6 is attached. The left inner thigh tape portion 52b has the same configuration as the right inner thigh tape portion 52a, so its description is omitted.
[0039] As shown in Figures 8 and 10, in the crotch tape section 52c, the lower edge of the front body fabric 31, in which the reverse front fabric 34a is bonded to the front center fabric 33c via hot melt H, and the lower edge of the back body fabric 32, in which the second reverse back fabric 34h is bonded to the front right back fabric 33g via hot melt H, are joined together with an ultrasonic sewing machine. The joined portion is then pinched (S1), and the third tape T5 is bonded over the seam allowance Y formed by the pinching.
[0040] As shown in Figure 8, in the crotch tape portion 52c, after the third tape T5 is adhered, at least one or more discontinuous sections G are formed in the width direction of the crotch portion 23 where the third tape T5 is not continuous. In this embodiment, two discontinuous sections G are provided.
[0041] More specifically, the joints where the front body fabric 31 and the back body fabric 32 are joined tend to be more rigid than other parts because hot melt or tape material is laminated therein. In contrast, by providing a dividing section G in the crotch tape section 52c, the rigidity of parts that should be soft when in contact with the wearer, such as the crotch section 23, is reduced, thereby preventing interference with the wearer's movements. In other words, the dividing section G functions as a rigidity reduction section in the crotch section 23.
[0042] As shown in Figures 8 and 10, in the crotch tape portion 52c, the third tape T5, the seam allowance Y, and the front bodice fabric 31 are overlapped, and multiple bar tackings (S2) are formed in three places. The bar tackings S2 are divided and arranged in the center of the width direction of the main body portion 2 and on both sides of the center. By providing bar tackings S2, the tear strength of the crotch portion 23 can be improved, and the rigidity of the crotch portion 23 can be reduced compared to when bar tackings S2 are formed continuously along the crotch portion 23 without being divided.
[0043] In this embodiment, the bolt fasteners S2 on both sides are provided so as to coincide with the widthwise position of the divided portion G. By providing the bolt fasteners S2 at a position corresponding to the divided portion G, where the tear strength is reduced compared to the portion without the divided portion G, the reduction in the tear strength of the divided portion G can be suppressed.
[0044] As shown in Figure 10, in the crotch tape portion 52c, a woven or knitted base fabric tape T6, which is wider than the third tape T5, is joined to the back side (body surface side) of the third tape T5.
[0045] As shown in Figure 1, when the hem 22 is twisted and the swimsuit 1 is worn, the crotch tape 52 is twisted inward in the width direction, starting from the upper ends of the right inner thigh tape portion 52a and the left inner thigh tape portion 52b. At this time, the right and left inner thigh lines 25a and 25b extend along a straight line L1 that extends along the inner thigh of the wearer 9. In this specification, as shown in Figure 6, the straight line L1 is a straight line extending from the line connecting the inner ankle bone 95 and the medial epicondyle 96 of the femur to the crotch portion 23.
[0046] As shown in Figures 3 and 5, each back tape 53 is provided on the inner surface of the main body 2 and has a first back tape 53a that extends vertically from the waist portion 21 to the hem portion 22, and a second back tape 53b that branches off from an intermediate position of the first back tape 53a and is connected to the inner thigh tape portions 52a and 52b.
[0047] Each first back tape 53a extends from the buttocks 97 to the vicinity of the back of the knee 98. The first back tape 53a is positioned in the widthwise center of the thigh 91, corresponding to the wearer's hamstrings. Each second back tape 53b intersects the first back tape 53a near the lower end of the buttocks 97 and wraps around the thigh 91 from the widthwise inner side, extending downwards and then wrapping around to the front.
[0048] As shown in Figures 4 and 5, the second back tape 53b has an upper portion 53c that slopes downward and inward in the width direction on the back side, and a lower portion 53d that slopes further downward and outward in the width direction on the front side. The upper portion 53c is positioned from near the lower part of the buttocks 97 to the middle part of the thigh 91 in the vertical direction, and the lower portion 53d is positioned from the middle part of the thigh 91 in the vertical direction to near the upper part of the knee 98. Each second back tape 53b makes it easier for the right inner thigh tape portion 52a and the left inner thigh tape portion 52b to twist inward in the width direction from the lower end side when the hem 22 is twisted to put on the swimsuit 1.
[0049] Figure 11 is an enlarged rear view that shows a magnified area of the region indicated by arrow XI in Figure 5, with a schematic cross-section of a portion of it. As shown in Figure 11, in this embodiment, the first back tape 53a is constructed by laminating a fourth tape T7 with a width of 10 mm, a fifth tape T8 with a width of 15 mm, and a grip tape T9 with a width of 20 mm in this order. Hot melt H is placed between these tapes T7, T8, and T9, or between the main body 2 and the tapes. The first back tape 53a is heat-pressed to the front left back fabric 33f after joining the inner edge portion in the width direction of the first back fabric 34f and the outer edges portion in the width direction of the second back fabric 34h and the third back fabric 34j via hot melt H. The inner edge portion in the width direction of the first back fabric 34f and the outer edges portion in the width direction of the second back fabric 34h and the third back fabric 34j are attached to the first back tape 53a with a gap in the width direction. The recovery stress of the first back tape 53a when stretched by 30% is preferably set to 0.6N or more and 14.74N or less, and in this embodiment, for example, it is 5.43N.
[0050] The second back tape 53b is constructed by laminating a 10mm wide sixth tape T10 and a 20mm wide woven or knitted base fabric tape T11 in that order. Hot melt H is placed between these tapes T10 and T11, or between the main body 2 and the sixth tape T10. The second back tape 53b is connected to the lower edge of the second back fabric 34h and the upper edge of the third back fabric 34j via the hot melt H. Front left back fabric After joining with 33f, the joint portion is heat-sealed. The lower edge of the second backing fabric 34h and the upper edge of the third backing fabric 34j are attached to the second backing tape 53b with a gap in the width direction. The recovery stress of the second backing tape 53b when stretched by 30% is preferably set to 0.77N or more and 10.64N or less, and in this embodiment, for example, it is 3.87N. In other words, the tensile stress of the second backing tape 53b is smaller than that of the first backing tape 53a.
[0051] As shown in Figures 4 and 5, the main body 2 further includes a central abdominal tape 54 provided at the joint between the front center fabric 33c, the front left front fabric 33d, and the front right front fabric 33e, and in the center of the back Front left back fabric 33f and Front right back fabric Each joint is reinforced by attaching a tape 55 to the center of the spine, which is located at the joint with 33g.
[0052] As shown in Figure 1, the swimsuit 1 has a marker P to guide the amount of twisting. In other words, when the swimsuit 1 is worn, the hem 22 is twisted to match the marker P, causing the waist portion 21 to twist from the hem 22 to the hem 22, which inwardly rotates the hip joint 93 of the wearer 9. In this embodiment, the marker P is made of bar tack sewn with thread of a different color from the sewing thread. In this embodiment, the marker P is positioned in the circumferential direction, roughly coinciding with the point where the inseam line 25 and the hem 22 intersect. Figure 12 shows the swimsuit 1 in a state where the hem 22 is twisted when worn. When wearing the swimsuit 1, the marker P and the inseam line 2, indicated by the dashed line, are shown. 5By twisting the hem portion 22 and aligning the marker P with the wearer's inner thigh point P2, the wearer's hip joint is internally rotated from the waist portion 21 to the hem portion 22, as shown by arrow B in Figure 12.
[0053] Figure 13 is a schematic diagram illustrating the hem 22 of swimsuit 1 when worn without twisting. As shown in Figure 13, the marker P is located on the front side of the inner thigh point P2 of the wearer 9 in the circumferential direction of the hem 22. More specifically, the ratio of the distance D1 from the marker P to the inner thigh point P2 of the wearer 9 to the circumference D of the hem 22 is set to 10.8% or more and 21.6% or less. The ratio of the distance D1 from the marker P to the inner thigh point P2 of the wearer to the circumference D of the hem 22 can also be rephrased as the amount of twist of swimsuit 1. The predetermined amount of twist, the upper and lower limits of the amount of twist and above The method for setting the lower limit will be explained in detail in the examples.
[0054] As shown in Figure 6, in this embodiment, the inner thigh point P2 is defined as the point where the hem 22 of the swimsuit 1 intersects with the straight line L1 connecting the inner ankle bone 95 and the medial epicondyle 96 of the femur when the swimsuit 1 is fitted to a specific mannequin (a mannequin manufactured by Nanairo Co., Ltd.: MD-20A (men's)).
[0055] Thus, when the swimsuit 1 is worn twisted, the inner thigh seam 25 is also twisted inward towards the thigh 91. To address this, the length of the inner thigh seam 25 is set so that the lower end of the inner thigh seam 25 is positioned appropriately after the swimsuit 1 is worn twisted. Specifically, as shown in Figure 6, the ratio of the distance D3 between the hem 22 of the swimsuit 1 and the knee center 99 to the length L21 of the thigh 91 should be set to 13% or more and 21% or less, for example, set to 13%. If the ratio of the distance D3 is less than 13.5%, the hem 22 is likely to overlap with the knee height when twisted (when the marker P is placed on the inner thigh), and the regulations may not be satisfied. If the ratio of the distance D3 exceeds 20.9%, the length of the fabric from the waist 21 to the hem 22 becomes insufficient, and the inward rotation effect tends to decrease.
[0056] In this specification, as shown in Figure 6, the center of the patella of a particular mannequin 90 is defined as the knee center 99, and the length of the straight line L2 connecting the patella center 99 and the anterior superior iliac spine 100 is defined as the length L21 of the thigh 91. The distance D3 between the hem 22 and the knee center 99 is the distance between the point where the straight line L2 intersects the hem 22 and the knee center 99 when the swimsuit 1 is dressed on the particular mannequin 90. In this embodiment, the distance D3 between the hem 22 and the knee center 99 only needs to be set to 63.7 mm or more and 102.9 mm or less, for example, it is set to 66 mm.
[0057] Figure 14 shows (a) a front view, (b) a side view, (c) a back view, and (d) a schematic diagram of the hem 122 of the first women's swimsuit 101 when worn without twisting. Figure 15 shows (a) a front view, (b) a side view, (c) a back view, and (d) a schematic diagram of the hem 222 of the second men's swimsuit 201 when worn without twisting. Figure 16 shows (a) a front view, (b) a side view, (c) a back view, and (d) a schematic diagram of the hem 322 of the second women's swimsuit 301 when worn without twisting. The configurations of the first women's swimsuit 101, the second men's swimsuit 201, and the second women's swimsuit 301 will be explained with reference to Figures 14 to 16.
[0058] As shown in Figure 14, the first women's swimsuit 101 has a main body 102 having an upper body portion 111 that covers the upper body and a lower body portion 112 that covers the lower body, an anti-slip member 104 attached to the inner surface of the main body 102 to improve the adhesion and fit of the swimsuit 101 to the wearer's skin, a tape member 105 attached to the main body 2, and a mark P10 that guides a predetermined amount of twist of the hem portion 22.
[0059] The main body 102 is made of stretchable fabric, similar to the first men's swimsuit 1. A chest lining 111a is placed in the chest area of the main body 102, a waist lining 112a is placed around the waist area, and an inner thigh lining 112b is placed on the inner thigh side of the thigh area 91. The first stretchable fabric located in the thigh area 91 of the main body 102 (the fabric in the area a1 in Figure 14) has the same stress at 30% stretch as the first stretchable fabric of the first men's swimsuit 1, and the second stretchable fabric sex The fabric (the fabric in area b1 of Figure 14) has the same stress at 30% elongation as the second stretch fabric of the first men's swimsuit 1. The main body 102 has an anti-slip member 104 attached to the hem 122, an inner thigh tape 152 attached to the inner thigh seam 125, and a back tape 153 attached to the back side. The back tape 153 is provided on the inner surface of the main body 102 and has a first back tape 153a that extends vertically from the waist 121 to the hem 122, and a second back tape 153b that branches off from an intermediate position of the first back tape 153a and connects to the inner thigh tape 152.
[0060] The first back tape 153a is positioned in the widthwise center of the thigh 91, corresponding to the wearer's hamstrings. Each second back tape 153b intersects the first back tape 153a near the lower end of the buttocks 97 and is positioned to wrap around the thigh 91 inward in the widthwise direction while moving downward. The lower end of each second back tape 153b is connected to the inner thigh tape 152 at the crotch. In other words, the first women's swimsuit 101 does not have side tapes 51.
[0061] The ratio of the distance D11 from the marker P10 to the inner thigh point P12 of the wearer 9 to the circumference D10 of the hem 122 (amount of twist) is set to 11.7% or more and 23.4% or less. The inner thigh point P12 was set by dressing a specific mannequin (a mannequin manufactured by Nanairo Co., Ltd.: WD-20A (ladies)) in the first ladies' swimsuit 101. The amount of twist of the first ladies' swimsuit 101 is greater than the amount of twist of the first men's swimsuit 1. Because the first ladies' swimsuit 101 does not have side tapes 51, it tends to have a larger amount of twist than the first men's swimsuit 1. On the other hand, because the first ladies' swimsuit 101 has a top portion 111, the length in the body length direction at the thigh 91 is longer than that of the first men's swimsuit 1, and the area of fabric that is twisted is larger. As a result, when wearing the swimsuit 101, twisting the hem 122 causes the fabric to twist from the waist area above the anterior superior iliac spine to the hem 122, thus effectively providing internal rotation support. The method for setting the amount of twist will be explained in detail in the examples.
[0062] The ratio of the distance D103 between the hem 122 of the swimsuit 1 and the knee center 99 to the length L121 of the thigh 91 is set to, for example, 18.1%. In this embodiment, the distance D103 between the hem 22 and the knee center 99 is set to, for example, 85 mm.
[0063] As shown in Figure 15, the second men's swimsuit 201 includes a main body 202, an anti-slip member 204 attached to the inner surface of the main body 202 to improve the adhesion and fit of the swimsuit 201 to the wearer's skin, a tape member 205 attached to the main body 202, and a marker P20 that guides a predetermined amount of twist of the hem 222.
[0064] The main body 202 is made of stretchable fabric, similar to the first men's swimsuit 1. A waist lining 212a is placed around the waist of the main body 202. In other words, there is no lining in parts other than around the waist. The outer fabric of the main body 202 consists of a first stretchable fabric located on the front side of the thigh 91 and a second stretchable fabric located on the back side. sexThe fabric consists of a single continuous piece of fabric. The first stretchable fabric (the fabric in area a2 in Figure 15) and the second stretchable fabric sex The fabric (the fabric in area b2 of Figure 15) has the same stress at 30% elongation as the first stretch fabric of the first men's swimsuit 1. The anti-slip member 204 is attached to the waist portion 221 and the hem portion 222 of the main body portion 202, and the inseam tape 252 is attached to the inner thigh seam 225. In other words, the 2 Men's swimsuit 201 does not have side tapes 51 or back tapes 53.
[0065] The ratio of the distance D21 from the marker P20 to the inner thigh point P22 of the wearer 9 to the circumference D20 of the hem 222 (amount of twist) is set to 14.3% or more and 28.6% or less. The inner thigh point P22 was set by dressing a specific mannequin (a mannequin manufactured by Nanairo Co., Ltd.: MD-20A (men's)) in the second men's swimsuit 201, similar to the first men's swimsuit 1. The amount of twist of the second men's swimsuit 201 is greater than the amount of twist of the first men's swimsuit 1 and the first women's swimsuit 101. The second men's swimsuit 201 tends to have a larger amount of twist than the first men's swimsuit 1 because it does not have side tape 51. Furthermore, the second men's swimsuit 201 cannot increase the area of the twisted fabric like the first women's swimsuit 101, 1 The amount of twist is set to be greater compared to the women's swimsuit 101. The method for setting the amount of twist will be explained in detail in the example.
[0066] The ratio of the distance D203 between the hem 222 of the swimsuit 1 and the knee center 99 to the length L221 of the thigh 91 is set to, for example, 15.9%. In this embodiment, the hem 2 The distance D203 between point 22 and the knee center 99 is set to, for example, 78 mm.
[0067] As shown in Figure 16, the second women's swimsuit 301 has a main body 302 having an upper body portion 311 that covers the upper body and a lower body portion 312 that covers the lower body, an anti-slip member 304 attached to the inner surface of the main body 302 to improve the adhesion and fit of the swimsuit 301 to the wearer's skin, a tape member 305 attached to the main body 302, and a mark P30 that guides a predetermined amount of twist of the hem portion 322.
[0068] Figure 17 is a schematic diagram showing the unfolded state of the second women's swimsuit 301. As shown in Figure 17, the main body 302 is made of stretchable fabric, similar to the first men's swimsuit 1. A chest lining 311a is placed in the chest area of the main body 302, and a waist lining 312a is placed around the waist area. The outer fabric of the main body 302 consists of a first stretchable fabric located on the front side of the thigh area 91 and a second stretchable fabric located on the back side. sex The fabric consists of a single continuous piece of fabric. The first stretchable fabric (the fabric in area a3 in Figure 16) and the second stretchable fabric sex The fabric (the fabric in area b3 of Figure 16) has the same stress at 30% elongation as the first stretchable fabric of the first men's swimsuit 1. The main body 302 is made of stretchable fabric, similar to the first men's swimsuit 1. The anti-slip member 304 is attached to the waist portion 321 and the hem portion 322, and the inseam tape 352 is attached to the inner thigh seam 325. The second women's swimsuit 301 does not have side tapes 51 and back tape 53.
[0069] The ratio of the distance D31 from the marker P30 to the inner thigh point P32 of the wearer 9 to the circumference D30 of the hem 322 (amount of twist) is set to 11.55% to 23.1%. The inner thigh point P32 was determined by dressing a specific mannequin (a mannequin manufactured by Nanairo Co., Ltd.: WD-20A (women's)) in the second women's swimsuit 301, similar to the first women's swimsuit 101. The amount of twist in the second women's swimsuit 301 is roughly the same as that of the first women's swimsuit 101. The second women's swimsuit 301, like the first women's swimsuit 101, does not have side tapes 51, and therefore tends to have a larger amount of twist than the first men's swimsuit 1. On the other hand, because it has an upper garment portion 311, the length in the body length direction of the thigh portion 91 is longer than that of the first men's swimsuit 1, and the area of fabric that is twisted is larger. As a result, Second Ladies When wearing swimsuit 301, twisting the hem 322 causes the fabric to twist from the waist area above the anterior superior iliac spine to the hem 322, thus effectively providing internal rotation support. The method for setting the amount of twist will be explained in detail in the examples.
[0070] The ratio of the distance D303 between the hem 322 of the swimsuit 301 and the knee center 99 to the length L321 of the thigh 91 is set to, for example, 20.9%. In this embodiment, the distance D303 between the hem 322 and the knee center 99 is set to, for example, 98 mm.
[0071] The relationship between the structure and the amount of twist of the first men's swimsuit 1, the first women's swimsuit 101, the second men's swimsuit 201, and the second women's swimsuit 301 is summarized below.
[0072] The stress at 30% elongation is greater on the inner thigh on the back side (area b in Figure 1) than on the outer thigh on the front side (area a in Figure 1). In the first men's swimsuit 1 equipped with side tape 51, the predetermined amount of twist that prevents wrinkles from forming when the hem 22 is twisted during wear is 21.6%. The ratio of the distance D1 from the marker P to the inner thigh point P2 of the wearer 9 to the circumference D of the hem 22 of the first men's swimsuit 1 (hereinafter also referred to as "amount of twist") is set to be between 10.8% and 21.6%.
[0073] The stress at 30% elongation is greater on the inner side of the thigh on the back side (region b1 in Figure 14) than on the outer side of the thigh on the front side (region a1 in Figure 14), and the first women's swimsuit has an upper garment portion 111 that covers the upper body and a lower garment portion 112 that covers the lower body. 1 In 01, the predetermined amount of twist that prevents wrinkles from forming when the hem 122 is twisted before wearing is 23.4%. The amount of twist for the first women's swimsuit 101 is set to be between 11.7% and 23.4%.
[0074] In the second men's swimsuit 201, which does not have side tapes, the stress at 30% elongation is set to a predetermined tensile stress in the outer thigh on the front side (area a2 in Figure 15) and the inner thigh on the back side (area b2 in Figure 15). The predetermined amount of twist that prevents wrinkles when the hem 222 is twisted during wear is 28.6%. The amount of twist in the second men's swimsuit 201 is set to be between 14.3% and 28.6%.
[0075] In a second women's swimsuit 301 having an upper garment portion 311 covering the upper body and a lower garment portion 312 covering the lower body, the stress at 30% elongation is set to a predetermined tensile stress in the outer thigh on the front side (area a3 in Figure 16) and the inner thigh on the back side (area b3 in Figure 16), and the predetermined amount of twist that does not cause wrinkles when the hem portion 322 is twisted when worn is 23.1%. The amount of twist of the second women's swimsuit 301 is set to be between 11.55% and 23.1%.
[0076] When wearing the first men's swimsuit 1, the first women's swimsuit 101, the second men's swimsuit 201, and the second women's swimsuit 301 by twisting the hems 22, 122, 222, and 322 so that the marks P, P10, P20, and P30 of each swimsuit align with the inner thigh points P2, P12, P22, and P32, a wearing error of about 1 cm may occur in the forward and backward directions of the twist, centered on the inner thigh points P2, P12, P22, and P32. However, even if such a wearing error occurs, the effect of internal rotation can still be achieved. [Examples]
[0077] Sensory evaluation, swimming efficiency evaluation, and swimming speed evaluation tests were conducted on the swimsuits of the comparative example and the example. The results of these measurements and evaluation tests are shown in Table 1.
[0078] Comparative Example 1 shows a conventional swimsuit worn without twisting. Comparative Example 2 shows the swimsuit according to the present invention worn with a twist exceeding a predetermined amount. Example 1 shows the swimsuit according to the present invention worn with a twist of 50% of a predetermined amount. Example 2 shows the swimsuit according to the present invention worn with a twist of a predetermined amount.
[0079] Comparative Example 2, Example 1, and Example 2 used four types of swimwear according to the present invention: the first men's swimwear 1 shown in Figure 1, the first women's swimwear 101 shown in Figure 14, the second men's swimwear 201 shown in Figure 15, and the second women's swimwear 301 shown in Figure 16.
[0080] The predetermined amount of twist differs for each swimsuit (Men's Swimsuit 1, Women's Swimsuit 101, Men's Swimsuit 201, Women's Swimsuit 301). In other words, each swimsuit has a set amount of twist that is appropriate for it. The method for setting each predetermined amount of twist was determined by evaluating the comfort (wearability) when multiple subjects (20 male and female university students) wore the swimsuits according to the present invention while twisting them.
[0081] Specifically, the amount of twisting required to generate internal rotation support while wearing each swimsuit without causing discomfort such as large wrinkles was determined as a predetermined amount of twist for the first men's swimsuit 1, the first women's swimsuit 101, the second men's swimsuit 201, and the second women's swimsuit 301, respectively. In this embodiment, large wrinkles caused by twisting the swimsuit are, for example, wrinkles that create water resistance while swimming, and are generally preferably 3 mm or less. In this embodiment, wrinkles that protrude 2 mm or more from the surface of the swimsuit when worn are defined as such.
[0082] The predetermined amount of twist for each swimsuit is set to 21.6% for the first men's swimsuit 1, 23.4% for the first women's swimsuit 101, 28.6% for the second men's swimsuit 201, and 23.1% for the second women's swimsuit 301. In other words, each amount of twist is the ratio of the distances D1, D11, D21, D31 from the markers P, P10, P20, P30 to the wearer's inner thigh points P2, P12, P22, P32 to the circumferences D, D10, D20, D30 of the hem 22, 122, 222, 322 in each wearing state. Therefore, each marker P, P10, P20, P30 is positioned at a distance of D1, D11, D21, D31 (each circumference D, D10, D20, D30 × each amount of twist) from each inner thigh point P2, P12, P22, P32.
[0083] The sensory evaluation of wearability involved subjects (20 male and female university students) who wore the swimsuits of Comparative Example 1, Comparative Example 2, Example 1, and Example 2 using the respective wearing methods, and evaluated the comfort level. More specifically, subjects were asked to rate the swimsuits as unacceptable (×) if they produced significant wrinkles while wearing them.
[0084] Swimming efficiency was evaluated using the average value of the Strauhull number St during full-power dolphin kicks for subjects wearing the swimsuits of Comparative Example 1, Example 1, and Example 2 in their respective wearing methods. The Strauhull number was calculated using the following formula. The Strauhull number St is a dimensionless number obtained by standardizing the kick width A with the ratio of average swimming speed U to kick frequency f. A lower Strauhull number St is considered to indicate better efficiency.
[0085]
number
[0086] In evaluating swimming efficiency, one cycle of the underwater dolphin kick was defined as the time from when the toes reached their highest point in the vertical direction to when they reached the next highest point. Data from 10 consecutive kick cycles was used for analysis. From the toe coordinate data, the kick width A and kick frequency f were calculated. Kick width A was defined as the vertical distance from the highest to the lowest point of the toe in the vertical direction during one kick cycle, and kick frequency f was defined as the reciprocal of the time required for one kick cycle.
[0087] The swimming speed evaluation is the average of the swimming speeds measured when subjects wearing the swimsuits of Comparative Example 1, Example 1, and Example 2 in their respective wearing methods swam 15m using a full-power dolphin kick.
[0088] [Table 1]
[0089] As is clear from Table 1, exceeding the predetermined amount of twist, as in Comparative Example 2, tends to worsen wearability. More specifically, in Comparative Example 2, excessive twisting results in uneven compression, causing discomfort when worn. Furthermore, excessive internal rotation support hinders the wearer's movement toward external rotation. In addition, large wrinkles form in the swimsuit, creating resistance. Good wearability was obtained for Comparative Example 1, Example 1, and Example 2. From the results in Table 1, it is preferable to set the predetermined amount of twist of the swimsuit according to the present invention as the upper limit of the amount of twist. Note that swimming efficiency and swimming speed were not evaluated for Comparative Example 2, which received a failing grade for wearability.
[0090] The trends in the evaluation tests for swimming speed and swimming efficiency were generally consistent, and in Examples 1 and 2, where the swimsuit was worn twisted to a predetermined amount, swimming speed and swimming efficiency improved compared to Comparative Example 1. In particular, in Example 2, swimming efficiency improved by 3% and swimming speed improved by 2%. Based on these results, it is preferable to set the lower limit of the twist amount to 50% of the predetermined twist amount.
[0091] The swimsuit 1 according to this embodiment provides the following effects.
[0092] (1) The method of wearing the swimsuit 1 is to wear the swimsuit 1 which is made of an elastic fabric that covers at least the waist 92 and part of the lower body and has a predetermined compression, by twisting the hem 22 of the swimsuit 1 so that the mark P indicating the amount of twist provided on the swimsuit 1 is in a predetermined position.
[0093] According to this configuration, the swimsuit 1 having a predetermined compression can be appropriately twisted by the mark P indicating the amount of twist, thereby generating the desired torsional force. As a result, for example, the hip joint 93 from the waist 92 to the knee 98 of the wearer 9 that the swimsuit 1 contacts... internal rotation It is easy to apply the desired level of support to achieve the desired effect.
[0094] (2) The swimsuit 1 has a hem portion 22 through which the legs are inserted, and a hem tape 42 is provided on the hem portion 22 to suppress the slippage of the hem portion 22 against the thigh portion 91. For example, when the hem portion 22 is twisted when worn, if slippage occurs between the hem portion 22 and the wearer 9, it becomes difficult to maintain the twisted state of the hem portion 22 relative to the waist portion 21 when the hem portion 22 is twisted when worn, and the support force in the inward rotation direction becomes difficult to apply. In contrast, by suppressing the slippage of the hem portion 22 relative to the wearer 9, it becomes easier to fix the hem portion 22 in a twisted state relative to the waist portion 21. Furthermore, in this embodiment, the hem tape 42 is made of a silicone-coated tape to prevent slippage against the wearer's skin, so even if the hem portion 22 is twisted, it does not return to its original position and the inward rotation function is easily exerted.
[0095] (3) The swimsuit 1 has a waist portion 21 provided at the upper edge and positioned at the waist 92 of the wearer 9, and a waist tape 41 is provided on the waist portion 21 to suppress slippage of the waist portion 21 relative to the waist 92. With this configuration, the waist portion 21 adheres closely to the wearer's skin, etc., and slippage of the waist portion 21 relative to the wearer 9 is suppressed. More specifically, if slippage occurs between the waist portion 21, the hem portion 22 and the wearer 9, when the hem portion 22 is twisted to wear, it becomes difficult to maintain the twisted state of the hem portion 22 relative to the waist portion 21, and the support force in the inward rotation direction becomes difficult to act. In contrast, by suppressing slippage of the waist portion 21 relative to the waist 92, the hem portion 22 can be twisted while the waist portion 21 is fixed. In addition, in this embodiment, the waist tape 41, like the hem tape 42, is made of a silicone-coated tape to prevent slippage with the wearer's skin, so that slippage of the waist portion 21 is suppressed when the hem portion 22 is twisted, making it easier to exert the inward rotation function.
[0096] (4) The amount of twist is set to be 50% or more of a predetermined amount of twist that does not cause wrinkles when the hem 22 is twisted and worn, and less than or equal to the predetermined amount of twist. The predetermined amount of twist is the limit of twist that does not cause wrinkles when the swimsuit is twisted and worn, in other words, the amount of twist that does not hinder wearability. With this configuration, the amount of twist can be set appropriately, making it easier to obtain an internal rotation effect more effectively. Specifically, if the amount of twist is less than 50% of the predetermined amount of twist, it is difficult to obtain an internal rotation effect. On the other hand, if the amount of twist exceeds the predetermined amount of twist, wrinkles that create water resistance are likely to form in the swimsuit. Also, excessive twisting can easily cause uneven compression, which can cause discomfort to the wearer, or the internal rotation effect may become too great, excessively restricting movement.
[0097] (5) The marker P may be composed of an inner thigh line 25. For example, an inner thigh line 25 that is inclined toward the front of the wearer 9 toward the hem 22 can be twisted to position the hem 22 on the inner thigh of the wearer 9, thereby obtaining the desired amount of twist.
[0098] (6) When the swimsuit 1 is dressed on a predetermined mannequin without twisting, the ratio of the distance D3 from the center of the kneecap 99 to the hem 22 to the length L21 of the thigh 91 of the predetermined mannequin is 13% or more and 21% or less. With this configuration, even when the marker P is the inner thigh line 25, the length of the inner thigh line 25 is set so that the lower end of the inner thigh line 25 after twisting is positioned at a desired vertical position, thus preventing the inner thigh line 25 from becoming excessively long after twisting.
[0099] (7) The swimsuit 1 is provided with a side tape 51 that is located on the outside in the width direction and extends from the waist portion 21 to the hem portion 22, and has a curved portion 51c in the part corresponding to the wearer's greater trochanter 94. With this configuration, when the swimsuit 1 is twisted when worn, the side tape 51 is also twisted together. Therefore, the side tape 51 acts to turn the greater trochanter 94 inward, and the hip joint 93 is more effectively internal rotation It's easy to do.
[0100] (8) The swimsuit 1 has a first back tape 53a which is a band-shaped strip extending along the length of the body from each buttock 97 to the thigh 91 and has a higher tensile stress than other parts, and a second back tape 53b which intersects with the first back tape 53a near the lower end of the buttock 97 and extends so as to the hem 22 it is located inward in the width direction and has a higher tensile stress than other parts.
[0101] With this configuration, the first back tape 53a and the second back tape 53b make it easier for the back of the thigh 91 to be pulled upward when lying face down, thus making it easier to maintain an efficient posture when performing an up kick while lying face down and moving the leg up and down.
[0102] (9) The second back tape 53b has a lower portion 53d that wraps around to the front and a lower end that is located near the lower end of the inner leg line 25. As a result, the second back tape 53b intersects with the first back tape 53a, making it easier for the inner leg line 25 to be twisted inward, and for the hem portion 22 to be kept in a twisted state.
