Description

[Technical Field]

[0001] The present invention relates to underwear, and more particularly to underwear including an underwear body and an elastic band. [Background technology]

[0002] Lower back pain is a problem that many people suffer from. Lower back pain is often related to pelvic misalignment. In other words, if the pelvis is misaligned (shake or distorted) due to poor posture habits, it not only puts pressure on nerves and causes lower back pain, but also puts undue strain on the surrounding muscles, disrupting the body's balance and, over time, causing pain and discomfort in the lower back, back, hip joints, knees, etc.

[0003] In order to improve these symptoms, it is most important to correct the displaced pelvis to its correct position. In this regard, so-called conventional pelvic belts tighten the pelvis in the hope of correcting the displaced pelvis to its correct position, but in reality, this alone does not return the pelvis to its correct position.

[0004] In order to return the pelvis to its correct position, it is extremely important to support the pelvis while maintaining a certain degree of freedom of movement. This will facilitate the return of the pelvis to its original position, and is thought to fundamentally alleviate lower back pain caused by pelvic displacement. A belt designed from this perspective is described, for example, in Patent Document 1 below.

[0005] Patent Document 1 listed below describes "a belt that covers at least a part of the pelvis and is wrapped around the waist in a circumferential direction, comprising a horizontally elongated stretchable elastic sheet having a thickness of 0.5 to 4 mm, a graphite silica-containing fabric containing graphite silica-containing fibers provided on one side of the elastic sheet, a loop pile fabric provided on the other side of the elastic sheet, and a hook-and-loop fastener hook portion that detachably engages with the loop pile fabric and is provided on one side of the elastic sheet, and the belt is 5 to 10 cm wide." It also states, "This invention makes it possible to provide a belt that supports the pelvis while making it easier to maintain a state in which it can move freely to a certain extent, and that can warm the area around the pelvis by using far-infrared rays."

[0006] Meanwhile, underwear made with free-cut fabric has been manufactured and sold in recent years. Free-cut fabric is a fabric that does not fray even when cut anywhere, and examples include those made from rayon, nylon, and polyurethane. The blend ratios are, for example, 50% rayon, 40% nylon, and 10% polyurethane. Furthermore, underwear made with free-cut fabric feels less tight. Such free-cut fabric is described, for example, in Patent Document 2 below.

[0007] The following Patent Document 2 describes "an elastic warp knitted fabric characterized by interweaving synthetic fibers with a melting point of 185°C or less in a multilayer warp knitted fabric made using elastic fibers and non-elastic fibers." It also states, "In a warp knitted fabric made of elastic fibers with excellent stretchability, synthetic fibers with a melting point of 185°C or less are used as part of the multilayer warp knitted fabric, and are melted and fixed in a presetting step in processing, thereby providing an elastic warp knitted fabric suitable for free cutting with unfinished edges."

[0008] [Patent Document 1] Utility Model Registration No. 3226519 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-240183 Summary of the Invention [Problem to be solved by the invention]

[0009] However, until now, there has been no underwear that can support the pelvis while still allowing it to move freely to a certain extent.

[0010] The present invention is intended to solve the above-mentioned problems, and aims to provide underwear that supports the pelvis while making it easier to maintain a state in which the pelvis can move freely to a certain extent, and that is comfortable to wear. At the same time, another object is to provide underwear that can warm the muscles around the pelvis with the effect of far infrared rays and make movement easier. [Means for solving the problem]

[0011] In order to solve the above problems, the underwear of the present invention comprises an underwear main body made of a free-cut fabric and a stretchable, band-like elastic band attached to the underwear main body, the elastic band being attached to the underwear main body so as to wrap around the wearer's waist in a generally horizontal circumferential direction when worn. Specific aspects are listed below.

[0012] (Mode 1) This underwear consists of an underwear body made of free-cut fabric and a roughly band-shaped elastic band that is stretchable and attached to the underwear body, the elastic band having a stronger tightening force in the left-right direction than the underwear body, the elastic band being attached to the underwear body so that when worn, it wraps roughly horizontally around the wearer's waist in the circumferential direction, and the elastic band is adhered over almost its entire surface to the inside of the underwear body with numerous dot-shaped adhesive.

[0013] This underwear consists of an underwear main body made of free-cut fabric and a stretchy, band-like elastic band attached to the underwear main body, and when worn, the elastic band is attached to the underwear main body so as to wrap roughly horizontally around the circumferential direction of the wearer's waist, thereby supporting the pelvis while making it easier to maintain a state in which the pelvis can move freely to a certain extent.While the elastic band supports the pelvis, the free-cut fabric itself has little elasticity, making it easier to maintain a state in which the pelvis can move freely to a certain extent. Furthermore, the underwear body is made of a free-cut fabric, and the elastic band is adhered over substantially the entire surface to the inside of the underwear body with numerous adhesive dots, resulting in underwear that is comfortable to wear. Furthermore, since the elastic band is adhered over almost its entire surface to the "inside" of the underwear body with numerous "dot-shaped adhesives," the elastic band is less likely to come off, resulting in underwear with excellent durability. Since the outer underwear body can easily follow the expansion and contraction of the inner elastic band, the stress load on the dot-shaped adhesives is reduced.

[0014] (Mode 2) The underwear according to Mode 1, wherein the elastic band has a width of 5 to 10 cm in the vertical direction and approximately the same width in the horizontal direction.

[0015] This underwear supports the pelvis while making it easier to maintain a certain degree of freedom of movement.

[0016] (Aspect 3) The underwear according to aspect 1 or 2, wherein the thickness of the elastic band is 0.3 to 1.5 mm.

[0017] This underwear is more comfortable to wear. The thickness of the elastic band is more preferably 0.5 to 1 mm.

[0018] (Aspect 4) This is an underwear according to any one of aspects 1 to 3, in which the elastic band is attached to the underwear body so that, when worn, the center in the vertical direction is located below the same height as the anterior superior iliac spine of the wearer's waist.

[0019] This underwear supports the pelvis while making it easier to maintain a state in which the pelvis can move freely to a certain extent.

[0020] (Aspect 5) This is an underwear according to any one of Aspects 1 to 4, in which the elastic band is attached to the underwear body so that, when worn, the center in the vertical direction is located 1 to 10 cm below the anterior superior iliac spine of the wearer's waist.

[0021] This underwear supports the pelvis while still allowing it to move freely to a certain extent. It is more preferable that the elastic band is attached to the underwear body so that, when worn, the center in the vertical direction is located 2 to 5 cm below the anterior superior iliac spine of the wearer's waist.

[0022] (Aspect 6) The undergarment according to any one of Aspects 1 to 5, wherein the elastic bands, when deployed in a strip-like state, have both left and right end portions extending diagonally upward to the left and right, respectively.

[0023] When this underwear is worn so that the vertical center of the elastic band is positioned 1 to 10 cm below the anterior superior iliac spine of the wearer's waist, the elastic band tends to wrap around the wearer's waist approximately horizontally in the circumferential direction. When the elastic band is in a laterally deployed band-like state, it is preferable that both left and right ends thereof extend obliquely upward to the left and right at an angle of approximately 5 to 15 degrees.

[0024] (Aspect 7) An underwear according to any one of aspects 1 to 6, having presser members adhered to both left and right end edges of the elastic band and to the inside of the underwear body so as to sandwich both left and right end edges of the elastic band between the underwear body.

[0025] This underwear has better durability as the elastic bands are less likely to come off.

[0026] (Embodiment 8) The underwear according to any one of embodiments 1 to 7, wherein the upper end of the underwear body is located above the band-shaped elastic band.

[0027] This underwear is more comfortable to wear.

[0028] (Aspect 9) This is an underwear according to any one of aspects 1 to 8, in which a component other than the elastic band that has a stronger tightening force in the left-right direction than the underwear body is not attached to the back or side of the underwear body. The only components attached to the back and sides of the underwear body that have a stronger tightening force in the left-right direction than the underwear body are elastic bands, and no buttock tightening belts, for example, that tighten or lift the buttocks, are attached.

[0029] This underwear supports the pelvis while still allowing it to move freely to a certain extent. It also provides a comfortable fit. In the underwear according to any one of Aspects 1 to 8, it is preferable that a member other than the elastic band, which has a stronger tightening force in the left-right direction than the underwear main body, is not attached to the underwear main body.

[0030] (Aspect 10) The underwear according to any one of aspects 1 to 9, which is unsewn.

[0031] This underwear is even more comfortable to wear.

[0032] (Embodiment 11) The underwear according to any one of embodiments 1 to 10, wherein the underwear body and the elastic band contain black silica-containing fibers that contain fine powder of black silica.

[0033] This underwear can warm the pelvic area through far-infrared effects. [Effects of the Invention]

[0034] The present invention provides underwear that supports the pelvis while allowing it to move freely to a certain extent, and that is comfortable to wear. Furthermore, when black silica-containing fibers are used, the area around the pelvis can be warmed by the far-infrared effect. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0036] The underwear will be described below by way of example. The underwear consists of an underwear body and an elastic band. In addition to these components, the underwear (shorts) of this embodiment also has a presser foot and a crotch member. Figure 5 shows front and back views of the underwear turned inside out, illustrating the state in which the inside, which faces the wearer, is turned outward. It should be noted that the following embodiments are merely illustrative of the present invention, and the present invention is not limited to the following specific embodiments.

[0037] 1. Underwear body The underwear body 1 is made of free-cut fabric. Free-cut fabric is a fabric that will not fray even if it is cut anywhere. Therefore, it can be used as is. In other words, there is no need to sew the edges (for example, by folding the edge of the fabric and sewing it twice, or by covering the edge of the fabric with a separate piece of fabric or tape in a roughly U-shaped cross section and sewing it), and the edges do not become thick. This prevents marks from being left on the skin when it comes into contact with the skin, and also provides an excellent wearing comfort. Furthermore, unlike conventional bras, the lines do not show through outerwear, resulting in an excellent aesthetic appearance.

[0038] In this embodiment, the free-cut fabric is made of polyester, nylon, and polyurethane. The blend ratio is not particularly limited, but it can be, for example, 25% polyester, 48% nylon, and 27% polyurethane. The polyester can be made of black silica-containing polyester fiber (e.g., 75d) containing fine black silica powder, which can warm the pelvic area through far-infrared effects. The basis weight of the free cut fabric is not particularly limited, but for example, 114 g / m 2 It can be said that:

[0039] In this embodiment, the underwear body 1 is made up of a back portion 11 and an abdominal portion 12, as shown in Fig. 1. Fig. 1 is a front view of the back portion 11 and the abdominal portion 12, with the back portion 11 representing the inner surface of the underwear body 1 and the abdominal portion 12 representing the outer surface of the underwear body 1. In this embodiment, the back portion 11 is a sheet-like structure in which the back surface 111 and the left and right side surfaces 112 extending from the left and right sides of the back surface 111 are integrally formed. Elastic bands 2, which will be described later, are attached to the elastic band attachment points 20 of the back portion 11. The back portion 11 is valley-folded along the valley folds 113, so that the left and right side surfaces 112 are folded back. In this embodiment, the abdominal portion 12 is in the form of a sheet in which a ventral surface 121 and a crotch portion 122 extending downward from the center of the ventral surface 121 are integrally formed. Then, the left and right edges of the back portion 11 (the left and right edges of the folded left and right side surfaces 112) and the left and right edges of the abdomen portion 12 are, for example, glued together, and the center of the lower edge of the back portion 11 and the lower edge of the crotch portion of the abdomen portion 12 are, for example, glued together to form the underwear body.

[0040] In this embodiment, the left and right edges of the back portion 11 and the left and right edges of the abdomen portion 12, as well as the central lower edge of the back portion 11 and the lower edge of the crotch portion of the abdomen portion 12, are bonded together with numerous dot-shaped adhesives (not shown), and are not sewn at all. This is what is known as a seamless underwear body 1. In this embodiment, the dots of adhesive have a diameter of approximately 2 mm. The numerous dots of adhesive are spaced apart (1.5 to 2 mm) and adjacent dots of adhesive do not overlap. The dot adhesive will be described in detail later.

[0041] Furthermore, the underwear body 1 can be made long enough so that its upper edge is positioned at the wearer's navel or above the navel when worn. In this embodiment, as shown in Fig. 7, the underwear body 1 is made long enough so that its upper edge is positioned above the navel when worn.

[0042] 2. Elastic band The elastic band 2 is generally strip-shaped and stretchable, and has a stronger tightening force in the left-right direction than the underwear body 1.

[0043] In this embodiment, a free-cut fabric made of polyester and polyurethane is used for the elastic band 2. There are no particular restrictions on the blend ratio, but it can be, for example, 90% polyester and 10% polyurethane. The polyester can be made of black silica-containing polyester fiber (e.g., 75d) that contains fine black silica powder, which can warm the area around the pelvis through far-infrared effects.

[0044] In this embodiment, the width of the elastic band 2 (the length in the vertical direction in FIG. 2) is 6 cm, and the width is generally the same in the left-right direction, which is the longitudinal direction. Here, "generally the same width" refers to the width at the center of the left-right direction of the elastic body 2 (the length in the vertical direction in FIG. 2) as the reference width, and includes a range of, for example, ±3% or ±5% from this width. Also, in this embodiment, the thickness of the elastic band is 0.8 mm. The elastic band has a stronger tightening force in the left-right direction than the underwear body itself; specifically, the stress of the elastic band when stretched 50% in the horizontal direction (longitudinal direction) is preferably 1.1 to 2.0 times the stress of the free-cut fabric used in the underwear body when stretched 50% in the horizontal direction (circumferential direction).

[0045] In this embodiment, as shown in Fig. 2, when the elastic band 2 is in a laterally unfolded strip-like state before being attached to the underwear body 1, both left and right end portions 22 extend obliquely upward to the left and right relative to the laterally strip-like direction. In this embodiment, both left and right end portions of the elastic band extend obliquely upward to the left and right at an angle θ of approximately 10 degrees relative to the laterally strip-like direction. It is preferable that the left and right angles θ are approximately equal.

[0046] Such elastic bands 2 are attached to the underwear body 1. Specifically, as shown in Fig. 3 and Fig. 5, the elastic bands 2 are attached to the underwear body 1 so that, when worn, they wrap around the wearer's waist in a generally horizontal circumferential direction. In detail, the elastic band 2 is attached to the underwear body 1 so that the elastic band 2 is linear in the left-right direction in the back view (inverted back view) so that it wraps around the wearer's waist approximately horizontally when worn, and the end 22 of the elastic band 2 is attached to the underwear body 1 so that the end 22 of the elastic band 2 in the front view (inverted front view) approximately overlaps with the elastic band 2 that is linear in the left-right direction in the back view. The elastic band 2 has almost the entire surface adhered to the inside of the underwear body 1 with a large number of adhesive dots.

[0047] In this embodiment, the elastic band 2 is attached to the underwear body so that, when worn, the center in the vertical direction is located below the same height as the anterior superior iliac spine of the wearer's waist. More specifically, the elastic band 2 is attached to the underwear body so that, when worn, the center in the vertical direction is located 1 to 5 cm below the anterior superior iliac spine of the wearer's waist.

[0048] Furthermore, in this embodiment, the elastic band 2 is attached to the underwear body 1 so that the upper end of the underwear body 1 is located above the elastic band 2.

[0049] In this embodiment, the elastic band 2 has almost the entire surface adhered to the inside of the underwear body 1 with a large number of adhesive dots 4, as shown in FIG.

[0050] The dot-shaped adhesive may be, for example, a natural resin or a synthetic resin. Among these, synthetic resins are preferred, and thermoplastic resins are more preferred. For example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, polytetrafluoroethylene, polyacrylic, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyethersulfone, polyetheretherketone, polyimide, polyamideimide, and other polymer compounds are not particularly limited, and various types may be used.

[0051] The size of the dots of the adhesive can be, for example, 0.5 to 4 mm in diameter. Within this range, the durability of the bonded portion increases. The size of the dots of adhesive is preferably 1 to 3 mm in diameter. In this embodiment, the dots of adhesive have a diameter of approximately 2 mm.

[0052] The numerous dots of adhesive are spaced apart from one another and do not overlap. The spacing between the dots of adhesive can be, for example, 1 to 5 mm. The spacing between the dots of adhesive is preferably 1.5 to 2 mm.

[0053] The left and right end edges of the elastic band 2 are sandwiched between the underwear body 1 and the pressing members 3, as will be described later.

[0054] 3. Retaining member The underwear W of this embodiment has a presser member 3. The presser member 3 is preferably made of the same free-cut fabric as the underwear body 1.

[0055] 3 and 5, the presser members 3 are adhered to both left and right edge portions 23 of the elastic bands 2 and the inside of the underwear body 1 from the inside of the underwear body 1 so as to sandwich both left and right edge portions 23 of the elastic bands 2 between the presser members 3 and the underwear body 1. In this embodiment, the presser members 3 are adhered to both left and right edge portions 23 of the elastic bands 2 and the inside of the underwear body 1 with a large number of dot-shaped adhesives (2 mm in diameter) not shown.

[0056] 4. Crotch member The underwear of this embodiment has a crotch member 123. The crotch member 123 can be made of a material with excellent water absorption and deodorizing properties. In this embodiment, the crotch member is made of a free-cut fabric made of cotton, polyester, and polyurethane. The blend ratio is not particularly limited, but can be, for example, 35% cotton, 53% polyester, and 12% polyurethane. The polyester can be made of black silica-containing polyester fiber (e.g., 50d) containing fine black silica powder, which can impart far-infrared effects and deodorizing effects. In this embodiment, of the 53% polyester, approximately half is made of black silica-containing polyester fiber (50d) containing fine black silica powder.

[0057] 7. Wearing underwear 7 and 8 show examples of the underwear being worn. The elastic band 2 is attached to the inside surface of the underwear, and in the front view of FIG. 7, both left and right end portions 22 of the elastic band 2 are located on the left and right sides of the inside (wearer side) of the underwear. These left and right end portions 22 are continuous on the back of the wearer, as shown in the back view of FIG. 8, and the elastic band 2 is wrapped around the wearer's waist in a generally horizontal circumferential direction. The vertical center of the elastic band 2 is located below the anterior superior iliac spine of the wearer's lower back. Furthermore, the wearer's navel is hidden, and the underwear body 1 is long enough that its upper edge is positioned above the wearer's navel. In addition, other than the elastic bands 2, no members having a stronger tightening force in the left-right direction than the underwear body 1 are attached to the underwear body 1. The only components present on the back side (including the buttocks side) and sides of the wearer other than the underwear body 1 are the elastic bands 2, and no buttocks tightening bands or the like are present. Additionally, the underwear is seamless, meaning that no stitching is involved.

[0058] Although the present invention has been described above with reference to specific embodiments, the present invention is not limited to the above embodiments, and various changes and modifications can be made by those skilled in the art without departing from the scope of the claims attached to the application of this application.
