Description

[Technical field]

[0001] The present invention relates to shoulder straps for athletic upper garments. [Background technology]

[0002] Patent Document 1 discloses a shoulder strap for clothing that holds the garment in place to prevent it from slipping down, and has multiple holes that are biased to one side of the center of the strap in the width direction. This makes the tightening force (tensile stress) lower on the inside of the center of the strap in the width direction than on the outside, reducing the pressure on the part of the strap located on the inside in the width direction, and dispersing the pressure on the wearer's shoulders. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2002-138303 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, for example, a swimsuit for competitive swimming as an athletic top has a higher pressure than a general swimsuit or clothing, so the pressure on the shoulders from the shoulder straps tends to be higher. Therefore, as in Patent Document 1, simply providing multiple holes in the length direction of the shoulder straps is unlikely to provide a sufficient effect in reducing the pressure of the shoulder straps of the swimsuit for competitive swimming.

[0005] Furthermore, lowering the tensile stress of the shoulder straps as in Patent Document 1 reduces the lifting effect of the shoulder straps to prevent the torso of the competitive swimsuit from slipping down, which may make it difficult to obtain the lifting effect of the shoulder straps on the torso of the competitive swimsuit to prevent water from entering through the neck area, which is a major cause of water resistance.

[0006] To provide shoulder straps for an athletic top that can appropriately pull up the torso of the athletic top while dispersing the pressure applied to the shoulders of a wearer. [Means for solving the problem]

[0007] One aspect of the present invention is A shoulder strap with an extension side stress of 7.7N or more and 28N or less at 30% extension, The shoulder straps are connected to the front and back of the torso of the exercise upper garment, and have openings extending in the longitudinal direction along a center line of the width direction of the shoulder straps at a position including the center line of the width direction of the shoulder straps, In the longitudinal direction of the shoulder strap, the opening is longer than a non-opening portion of the shoulder strap that is not opened, The width of each of the inner portion located on the inner side in the width direction and the outer portion located on the outer side of the opening is set to be 1 / 3 or more and 1 / 2 or less of the width of the shoulder strap. To provide shoulder straps for an athletic top.

[0008] According to the present invention, the shoulder strap at the portion where the opening is provided is divided into an inner portion and an outer portion in the width direction at a predetermined length, so that the predetermined pressure applied to the shoulder by the shoulder strap can be easily distributed to the inner portion and the outer portion of the shoulder strap, compared to a non-opening portion. In addition, since the width of the inner portion and the outer portion are appropriately set, the decrease in the tensile stress of the entire shoulder strap can be suppressed. This allows the shoulder strap to appropriately pull up the torso while dispersing the pressure applied to the wearer's shoulder. If the width of the inner portion and the outer portion is less than 1 / 3 of the width of the shoulder strap, the width of the inner portion and the outer portion becomes too narrow, which may cause manufacturing defects such as an increase in surface pressure and a tendency to break. If the width of the inner portion and the outer portion exceeds 1 / 2 of the width of the shoulder strap, the inner portion and the outer portion will overlap. Effect of the Invention

[0009] According to the present invention, it is possible to provide shoulder straps for an athletic upper garment that can appropriately pull up the torso with the shoulder straps while dispersing the pressure on the wearer's shoulders. [Brief description of the drawings]

[0011] The present invention relates to shoulder straps for competitive swimming suits.

[0012] Fig. 1 is a front view of a competitive swimsuit (hereinafter also simply referred to as "swimsuit") 1 as athletic upper garment with shoulder straps according to the present invention. Fig. 2 is a back view of the swimsuit 1. As shown in Figs. 1 and 2, the swimsuit 1 has a torso 2 that covers the wearer's body, and a pair of left and right shoulder straps 31, 41 that span from the front to the back of the torso 2.

[0013] The torso 2 has a front side portion 21 that covers the wearer's chest to knees on the front side, and a rear side portion 22 that covers the wearer's back to knees on the rear side. The torso 2 is made of a stretchable fabric as a whole and has a predetermined wearing pressure.

[0014] The stretchable fabric is intended to be worn in a state of being in close contact with the wearer 9. The stretchable fabric preferably has an elongation side stress of 3.2 N to 15.6 N at 30% elongation in the body length (warp) direction, and in this embodiment, for example, 7.5 N. The stretchable fabric preferably has an elongation side stress of 2.4 N to 19.0 N at 30% elongation in the body width (weft) direction, and in this embodiment, for example, 6.5 N. In this embodiment, the recovery side stress of the stretchable fabric at 30% elongation in the body length direction is 0.297 N, and the recovery side stress at 30% elongation in the body width direction is 1.036 N.

[0015] The stress of the stretchable fabric when stretched in the body length direction and the body width direction was measured by preparing one piece of fabric each in the warp and weft directions, 50 mm wide and 200 mm long, fixing the fabric to a tensile tester (Shimadzu Corporation: Autograph AGS-X) with a gripping width of 65 mm above and below and a gripping distance of 100 mm, stretching the fabric at a tensile speed of 200 mm / min, reading the stress when the elongation rate was 30%, which was taken as the "elongation side stress", and recovering the fabric at a recovery speed of 200 mm / min when the elongation rate reached 100%, reading the stress when the elongation rate at the time of recovery was 30%, which was taken as the "recovery side stress". The stretchable fabric for which the tensile stress was measured corresponds to the fabric located on the front side of the wearer and covering the chest, more specifically, corresponds to the test piece cut out from the area indicated by a in Figure 1, and is of the same material as the fabric for the thighs.

[0016] 1 and 2, shoulder straps 31, 41 are hung across front portion 21 and rear portion 22 of torso 2. The pair of left and right shoulder straps 31, 41 includes a left shoulder strap 31 that is placed on the wearer's left shoulder and a right shoulder strap 41 that is placed on the wearer's right shoulder.

[0017] The left shoulder strap 31 is connected to the left upper edge 21a in the width direction at the upper edge of the front portion 21 and to the upper end 22a in the width direction center of the rear portion 22. The right shoulder strap 41 is connected to the right upper edge 21b in the upper edge of the front portion 21 and to the upper end 22a in the width direction center of the rear portion 22. In this embodiment, the rear ends of the left shoulder strap 31 and the right shoulder strap 41 are connected to the center C of the back.

[0018] FIG. 3 shows the left shoulder strap 31 in an unfolded state. FIG. 4 shows the right shoulder strap 41 in an unfolded state. Referring to FIG. 3 and FIG. 4, the left shoulder strap 31 and the right shoulder strap 41 have elasticity at least in the longitudinal direction. The left shoulder strap 31 and the right shoulder strap 41 only need to have an elongation side stress set to 7.7 N or more and 28 N or less when elongated by 30%, and is set to, for example, 27.5 N. The left shoulder strap 31 and the right shoulder strap 41 have a predetermined stress when elongated in the longitudinal direction at a predetermined ratio corresponding to the elongation rate when worn. In this embodiment, the longitudinal elongation rate of the left shoulder strap 31 when worn is 47%. The recovery side stress of the left shoulder strap 31 when elongated by 47% only needs to be set to 6.9 N or more and 11.03 N or less, and is set to, for example, 7.9 N. The left shoulder strap 31 for which the tensile stress was measured corresponds to the portion indicated by the arrow V in FIG. 3. In this embodiment, the longitudinal elongation rate of the right shoulder strap 41 when worn is 42%. The recovery side stress of the right shoulder strap 41 when elongated by 42% may be set to 6.2 N or more and 9.21 N or less, and is set to 6.64 N, for example. In this embodiment, the elongation side stress of the left shoulder strap 31 and the right shoulder strap 41 when elongated by 30% in the longitudinal direction is 27.5 N. The stress of the left shoulder strap 31 and the right shoulder strap 41 when stretched was measured by setting a gripping width of 5 mm above and below the two left openings 35, fixing them to a tensile tester (Shimadzu Corporation: Autograph AGS-X), stretching them at a tensile speed of 200 mm / min, reading the stress when the stretch rate was each stretch rate (42% or 47%) and recording it as the "stretch side stress", and when the stretch rate reached 100%, recovering at a recovery speed of 200 mm / min, reading the stress when the stretch rate was each stretch rate (42% or 47%) and recording it as the "recovery side stress". The recovery side stress of the left and right shoulder straps 31, 41 when stretched 42% to 47% may be, for example, 7.7 N or more and 29.1 N or less.

[0019] As shown in FIG. 3, the left shoulder strap 31 has a left shoulder strap main body portion 32, a left front connection portion 33 connected to the front portion 21, a left rear connection portion 34 connected to the rear portion 22, and a left opening 35 extending in the longitudinal direction.

[0020] The left shoulder strap main body 32 has a generally constant width W1, which is set to, for example, 22 mm. The left shoulder strap main body 32 spans from the rear side to a portion located on the front side of a position P1 (hereinafter also referred to as the "shoulder point") that corresponds to the top of the shoulder when laid flat, as shown by the two-dot chain line in Figures 1 and 3.

[0021] As shown in FIG. 3, the left front connection part 33 is continuous with one end part of the left shoulder strap main body part 32 on one longitudinal side.

The width of the right front connection part 43 is widest at the tip part, and the width W2 of the tip part is set to 159% of the width W1 of the right shoulder strap main body part 42, for example, 35 mm. As shown in FIG. 1, the right front connection part 43 is connected to the right upper edge part 21b of the front part 21. The right upper edge part 21b is a part where the neck part 21c and the right armpit opening 21e are connected.

[0027] As shown in FIG. 4, the right rear connection part 44 is continuous with the lower end of the right shoulder strap main body part 42. The right rear connection part 44 is a skirt-shaped part that spreads from the other end of the right shoulder strap main body part 42 toward both widthwise outer sides of the swimsuit 1. As shown in FIG. 2, the right rear connection part 44 is connected to the widthwise center part of the rear part 22. In this embodiment, the right rear connection part 44 is connected to the inside of the swimsuit 1 with respect to the left rear connection part 34, with the widthwise center of the right rear connection part 44 coinciding with the widthwise center of the left rear connection part 34. The lower edge part 44a of the right rear connection part 44, together with the lower edge part 34c of the left rear connection part 34, constitutes the widthwise center part of the back opening 23.

[0028] The shoulder straps 31, 41 and the openings 35, 45 will be described with reference to FIGS.

[0029] Referring to FIG. 3, the left opening 35 is a slit formed by a laser processing machine (so-called laser cutting). The cross section of the left opening 35 is melted during laser processing to have a molten cross section. The left opening 35 extends in the longitudinal direction along the center line C1 at a position including the center line C1 in the width direction of the left shoulder strap 31. In this embodiment, the left opening 35 is composed of a plurality of left openings 35. The left openings 35 are provided intermittently along the longitudinal direction of the left shoulder strap 31. The left openings 35 are arranged at equal intervals along the longitudinal direction. Between adjacent left openings 35, left non-openings 36 in which no left openings 35 are provided are formed.

[0030] The left openings 35 include a first left opening 35a provided across the left front connection portion 33 and the left shoulder strap body portion 32, and a second left opening 35b, a third left opening 35c, and a fourth left opening 35d provided in the left shoulder strap body portion 32. The length L1 in the longitudinal direction of each left opening 35 is a constant length, and is set to, for example, 40 mm. The length L1 of each left opening 35 is the length between the left opening upper end 35e located at the upper end of each left opening 35 and the left opening lower end 35f located at the lower end. The length L1 may be set to 43 mm.

[0031] The length L1 of each left opening 35 is set to be greater than the longitudinal length L2 of the left non-opening 36. The ratio of the length L2 of the left non-opening 36 to the length L1 of each left opening 35 is preferably 0% or more and 50% or less, and the length L2 of the left non-opening 36 is set to, for example, 10 mm. The length L2 of the left non-opening 36 is the length between the adjacent left opening 35, for example, the left opening lower end 35f of the third left opening 35c and the left opening upper end 35e of the fourth left opening 35d.

[0032] The ratio of the length of the portion where the multiple left openings 35 are provided (the total length of the multiple left openings 35) to the longitudinal length L of the left shoulder strap 31 may be set to be 50% or more and 93% or less, for example, 78%. In this embodiment, the length L of the left shoulder strap 31 is the length L of the left shoulder strap main body portion 32 and the left front connection portion 33, which have a roughly constant width in the left shoulder strap 31. The roughly constant width refers to the portion that is 27% or more and 159% or less of the width W1 of the left shoulder strap main body portion 32.

[0033] 3 and 5, the portion of the left shoulder strap 31 where the left opening 35 is provided is divided into an inner portion 37 and an outer portion 38 by the left opening 35. In this embodiment, the widths W3 of the inner portion 37 and the outer portion 38 are roughly the same and are preferably between 1 / 3 and 1 / 2 of the width W1 of the left shoulder strap 31, and are set to, for example, 11 mm.

[0034] 1 and 3, the left opening 35 is disposed at a position corresponding to the top of the wearer's shoulder when the swimsuit 1 is laid flat. More specifically, a shoulder point P1 is located at the longitudinal middle portion of the first left opening 35a.

[0035] As shown in FIG. 3, a left core 31c is disposed in the widthwise center of the left shoulder strap 31 to suppress twisting of the left shoulder strap 31 in the width direction. The left core 31c extends along the longitudinal direction of the left shoulder strap 31 and is disposed in a portion corresponding to the left front connecting portion 33 and the left shoulder strap main body portion 32. In this embodiment, the length L of the left shoulder strap 31 is equal to the length of the portion of the left shoulder strap 31 where the left core 31c is disposed. The left core 31c is disposed at a position corresponding to at least the longitudinal opening end of each left opening 35. More specifically, the left core 31c is disposed in a position overlapping the left opening upper end 35e and the left opening lower end 35f.

[0036] In this embodiment, the left opening 35 and the right opening 45 have roughly the same shape, so the right opening 45 will be described briefly.

[0037] 4, the right opening 45 has a configuration generally similar to that of the left opening 35. The right opening 45 has a first right opening 45a, a second right opening 45b, a third right opening 45c, and a fourth right opening 45d that are provided discontinuously along the longitudinal direction of the right shoulder strap 41, as well as a right non-opening 46 located between adjacent right openings 45.

[0038] 4 and 5, the portion of the right shoulder strap 41 where the right opening 45 is provided is divided into an inner portion 37 and an outer portion 38 by the right opening 35. In this embodiment, the widths W3 of the inner portion 47 and the outer portion 48 are roughly the same and are preferably greater than or equal to 1 / 3 and less than or equal to 1 / 2 of the width W1 of the right shoulder strap 41, and are set to, for example, 11 mm.

[0039] 1 and 4, the right opening 45 is disposed to correspond to the top of the wearer's right shoulder when the swimsuit 1 is laid flat. More specifically, a shoulder point P2 is located in the longitudinal middle portion of the first right opening 45a.

[0040] A right core material 41c is disposed in the widthwise center of the right shoulder strap 41. The right core material 41c extends along the longitudinal direction of the right shoulder strap 41 and is disposed in a portion corresponding to the right front connecting portion 43 and the right shoulder strap main body portion 42. In this embodiment, the length L of the right shoulder strap 41 is the same as the length of the portion of the right shoulder strap 41 where the right core material 41c is disposed, as with the left shoulder strap 31. The right core material 41c is disposed at a position corresponding to at least the longitudinal opening end of each right opening 45. More specifically, the right core material 41c is disposed in a position overlapping the right opening upper end 45e and the right opening lower end 45f.

[0041] Fig. 5 is a partially enlarged cross-sectional view of the portion indicated by the arrow V in Fig. 3. For the sake of convenience, the fabric and tape are shifted in Fig. 5, and the thickness of the fabric is emphasized. In this embodiment, the left shoulder strap 31 and the right shoulder strap 41 have roughly the same configuration, so only the left shoulder strap 31 will be described, and the reference number of the right shoulder strap 41 will be given in parentheses in Fig. 5.

In this embodiment, the width W1 of the base fabric portion 31a is set to, for example, 22 mm, but the width W1 may be any width W1 that complies with the regulations for competitive swimming suits, for example, 25 mm or less. The width W1 of the base fabric portion 31a is the same as the width of the left shoulder strap 31. The base fabric 31a is preferably made of a knitted base fabric tape.

[0046] 3 and 5, the left core 31c is made of a base fabric tape bonded with hot melt. In this embodiment, the left core 31c extends in the longitudinal direction over the entire left shoulder strap body 32 and the left front connection portion 33. The left core 31c is disposed so that the center in the width direction of the left core 31c coincides with the center line C1 of the left shoulder strap 31. The width W4 of the left core 31c is preferably set to 45% to 98% of the width W1 of the left shoulder strap 31, and is set to, for example, 90%. In this embodiment, the width W4 of the left core 31c is set to 20 mm.

[0047] The pair of folded pieces 31b are folded back from both widthwise sides of the left core material 31c toward the inside in the widthwise direction, with the center line C1 in between, and joined to the inside surface of the left core material 31c. The width W5 of each folded piece 31b is set to, for example, 10 mm. Both widthwise ends of the left core material 31c are covered by the folded pieces 31b.

[0048] When the pair of folded pieces 31b are folded inside the base fabric portion 31a, the ends of the pair of folded pieces 31b are arranged opposite each other. The ends of the pair of folded pieces 31b are spaced apart in the width direction, and the folded pieces 31b are not arranged near the center line C1. The folded pieces 31b do not overlap in the width direction. A gap G between the ends of the pair of folded pieces 31b is arranged at a position including the center line C1 and extends in the longitudinal direction. The tape member T is layered on the folded pieces 31b so as to cover the gap G from the inside.

[0049] The tape member T is made of a woven or knitted base fabric tape. The tape member T is preferably made of a knitted base fabric tape. In this embodiment, the tape member T extends in the longitudinal direction over the entire left shoulder strap main body portion 32. The tape member T is arranged so that the center in the width direction of the tape member T coincides with the center line C1 of the left shoulder strap 31. The width W6 of the tape member T is larger than the width of the gap G between the ends of the folded-back piece portions 31b, and is set to, for example, 15 mm.

[0050] Fig. 6 is a schematic rear view showing the area around a pair of left and right shoulder straps 31, 41 of the swimsuit 1 when it is turned inside out. As shown in Fig. 6, in this embodiment, the tape member T has a first tape member T1 arranged across the left and right shoulder straps 31, 41, a second tape member T2 provided at the left armpit opening 21d, and a third tape member T3 provided from the right shoulder strap main body portion 42 to the right rear connection portion 44.

[0054] The one end T21 is a portion that overlaps with the first left opening 35a in the longitudinal direction. The other end T22 is a portion that overlaps with the fourth left opening 35d in the longitudinal direction. The one end T21 and the other end T22 are disposed between the first tape member T1 and the folded-back piece portion 31b. More specifically, the one end T21 and the other end T22 have a five-layer structure including the base fabric portion 31a, the left core material 31c, the folded-back piece portion 31b, the one end T21 or the other end T22, and the first tape member T1.

[0055] One end T31 of the third tape member T3 is joined to the right rear connection portion 44 of the right shoulder strap main body 42, and the other end T32 is joined to the right rear connection portion 44. The third tape member T3 overlaps the first tape member T1 at the right shoulder strap main body 42, moves downward away from the first tape member T1, and terminates at the right rear connection portion 44.

[0056] The one end T31 is a portion that overlaps with the fourth right opening 45d in the longitudinal direction. The one end T31 is disposed between the first tape member T1 and the folded-back piece 41b. More specifically, the one end T31 has a five-layer structure including the base fabric portion 41a, the right core material 41c, the folded-back piece 41b, the one end T31, and the first tape member T1.

[0057] The swimsuit 1 according to this embodiment has the following advantages.

[0058] (1) The shoulder straps 31, 41 of the competitive swimsuit 1, which has a stress at 30% elongation set to be 7.7 N or more and 28 N or less, are connected to the front and back of the torso 2 of the competitive swimsuit 1, and have openings 35, 45 that extend longitudinally along the widthwise centerline C1 of the shoulder straps 31, 41 at a position including the centerline C1, and in the longitudinal direction of the shoulder straps 31, 41, the openings 35, 45 are longer than the non-openings 36, 46, and the width W3 of each of the inner portions 37, 47 located on the widthwise inner side and the outer portions 38, 48 located on the outer side of the openings 35, 45 is set to be 1 / 3 or more and 1 / 2 or less of the width W1 of the shoulder straps 31, 41.

[0059] According to this configuration, the shoulder straps 31, 41 at the portions where the openings 35, 45 are provided are divided into the inner portions 37, 47 and the outer portions 38, 48 in the width direction at a predetermined length, so that the predetermined pressure applied to the shoulders by the shoulder straps 31, 41 is more easily distributed to the inner portions 37, 47 and the outer portions 38, 48 of the shoulder straps 31, 41 than in the non-opening portions 36, 46. In addition, since the widths W3 of the inner portions 37, 47 and the outer portions 38, 48 are appropriately set, the decrease in the tensile stress of the entire shoulder straps can be suppressed. This allows the shoulder straps 31, 41 to appropriately pull up the torso 2 while dispersing the pressure applied to the shoulders of the wearer. If the widths W3 of the inner portions 37, 47 and the outer portions 38, 48 are less than 1 / 3 of the widths W1 of the shoulder straps 31, 41, the widths W3 of the inner portions 37, 47 and the outer portions 38, 48 become too narrow, which may cause manufacturing defects such as increased surface pressure and easy breakage. If the width W3 of the inner portions 37, 47 and the outer portions 38, 48 exceeds 1 / 2 the width W1 of the shoulder straps 31, 41, the inner portions 37, 47 and the outer portions 38, 48 will overlap.

[0060] (2) The length of the portion where the openings 35, 45 are provided is set to 50% or more and 93% or less of the longitudinal length L of the shoulder straps 31, 41. According to this configuration, the length of the openings 35, 45 is appropriately set to the length L of the shoulder straps 31, 41, so that the wearing pressure on the shoulders of the wearer can be more effectively distributed. If the length of the openings 35, 45 is less than 50% of the longitudinal length of the shoulder straps 31, 41, it is difficult to sufficiently reduce the wearing pressure. If the length of the openings 35, 45 exceeds 93% of the longitudinal length of the shoulder straps 31, 41, for example, the distance from the end of the core material becomes short, and the tear strength is likely to decrease.

[0061] (3) The openings 35, 45 are provided at positions P1, P2 which correspond to the tops of the wearer's shoulders when the competitive swimsuit 1 is laid flat. Therefore, by providing the openings 35, 45 at the tops of the shoulders where pressure is likely to be high, it is easier to effectively distribute pressure.

[0062] (4) Because the openings 35, 45 are provided intermittently along the longitudinal direction of the shoulder straps 31, 41, it is easier to avoid overlapping of the inner and outer parts compared to when the openings are provided continuously in the longitudinal direction, and this makes it possible to prevent problems such as increased pressure caused by overlapping of the inner and outer parts. In addition, this makes it possible to prevent problems such as tearing at the edge of the opening when worn, etc.

[0063] (5) The shoulder straps 31, 41 have a base fabric portion 31a extending in the longitudinal direction and a pair of folded-back pieces 31b that are integral with the base fabric portion 31a and are folded back to face the base fabric portion 31a, and core materials 31c, 41c are arranged between the base fabric portion 31a and the pair of folded-back pieces 31b at positions that correspond at least to the longitudinal opening ends 35e, 35f, 45e, 45f of the openings 35, 45.

[0064] According to this configuration, the tear strength of the opening edges 35e, 35f, 45e, and 45f of the openings 35 and 45 is likely to decrease, but by providing the cores 31c and 41c, the decrease in tear strength at the opening edges 35e, 35f, 45e, and 45f can be suppressed.

[0065] (6) The width W4 of the core material 31c, 41c relative to the width W1 of the shoulder strap is set to 45% or more and 98% or less, so that the core material 31c, 41c can be set to an appropriate width. For example, a step is unlikely to occur between a portion where the core material 31c, 41c is arranged and a portion where it is not arranged, and deformation in the width direction of the shoulder strap 31, 41, such as the step portion rolling up from the outside in the width direction toward the inside, can be suppressed. If the width W4 of the core material 31c, 41c relative to the width W1 of the shoulder strap 31, 41 is less than 45%, it is difficult to suppress deformation in the width direction of the shoulder strap 31, 41. If the width W4 of the core material 31c, 41c relative to the width of the shoulder strap 31, 41 exceeds 98%, it is likely to be difficult to manufacture.

[0066] (7) Because openings 35, 45 are configured as slits, it is easier to maintain the tensile stress without widening shoulder straps 31, 41, compared to openings provided with multiple holes or the like having a predetermined width. In other words, when shoulder straps 31, 41 have a constant width, it is possible to prevent a decrease in the tensile stress of shoulder straps 31, 41, compared to openings provided with multiple holes or the like having a predetermined width.

[0067] (8) Since the openings 35, 45 have welded cross sections, fraying of the cross sections of the openings 35, 45 can be suppressed.

[0068] In this embodiment, an example has been described in which the openings 35, 45 are configured with a plurality of slits, but this is not limited thereto, and the openings 35, 45 may be a single opening, or may be configured with a mixture of linear slits and dot-shaped through holes, for example, a dot-shaped through hole may be provided between adjacent slits.

[0069] In this embodiment, the length L1 of the openings 35, 45 is constant. However, the present invention is not limited to this, and the length L1 of the openings 35, 45 does not have to be constant.

[0070] In this embodiment, the openings 35, 45 are configured to extend along the center line C1 in the width direction of the shoulder straps 31, 41, but this is not limited to the above. The openings 35, 45 may have, for example, an oblique shape that slopes inward or outward in the longitudinal direction, or a wavy shape.

[0071] Although an example in which the openings 35, 45 are formed by a plurality of slits has been described, the present invention is not limited to this, and the openings 35, 45 may be a plurality of diamond-shaped openings arranged in the longitudinal direction of the shoulder strap. Also, the plurality of diamond-shaped openings arranged in the longitudinal direction may be provided in two or three rows in the width direction of the shoulder strap. The shape of the openings may be formed in a design such as a logo shape.

[0072] In this embodiment, a configuration has been described in which the left core material 31c and the right core material 41c are provided over the entire longitudinal direction, but this is not limited to this, and it is sufficient that the core material is provided in a position that overlaps at least with the opening ends 35e, 35f, 45e, 45f of the openings 35, 45 in the longitudinal direction of the shoulder strap 31.

[0073] In the present embodiment, a configuration in which the rear opening 23 is provided in the rear side portion 22 has been described, but the present invention is not limited to this, and the rear opening 23 does not necessarily have to be provided in the rear side portion 22 .

[0074] In this embodiment, the shoulder straps of the athletic top are applied to a competitive swimsuit, but the shoulder straps of the athletic top can be applied to other athletic tops such as a bra top.

[0075] The method of wearing the swimsuit of the present invention is not limited to the configuration of the above-mentioned embodiment, and various modifications are possible.
