[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-274501 Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above circumstances, the present invention aims to provide bottom clothing that fits naturally without slipping or rolling up due to changes in the wearer's posture, breathing, or size, and that also provides a supportive effect.

[0007] In order to solve the above-mentioned problems, the inventors discovered that by providing a folded portion at the upper back body of a bottom garment to create a double-layered structure, and by fastening the folded ends only at the left and right sides of the back without sewing or other joining, and leaving the rest of the fastening portion unattached, the width of the folded portion can move up and down, allowing the waist portion of the bottom garment to conform to the wearer's body even when the wearer's posture changes, such as bending and straightening the waist or protruding hips, and preventing the fabric from shifting or curling up at the waist. The present invention was completed based on this finding. [Means for solving the problem]

[0008] The invention according to claim 1 is A bottom garment, The upper back portion has a folded portion, and the folded portion is folded outward to form a double structure, The folded end of the folded-over portion is fastened to the back body by fastening portions on the left and right sides of the back body, and the portion other than the fastening portions is configured to have a flap structure, The left and right folded ends of the folded-back portion are joined to the front body along joining lines on the left and right sides of the front body, respectively.

[0009] The invention according to claim 2 is as follows: The bottom garment according to claim 1 relates to a fabric for forming the back body, which extends from the back through the sides to the front, crosses at the front, and is configured to overlap and cover the abdomen from both the left and right sides, with the ends of the fabric joined along the joining line.

[0010] The invention according to claim 3 is This relates to bottom clothing as described in claim 1 or 2, wherein the front hem is prepared as a raw cut piece of fabric that does not require edge processing, and the back hem has a hip-up panel structure formed by folding back the hem fold portion provided at the hem of the back body to create a double structure. [Effects of the Invention]

[0011] According to the invention of claim 1, in addition to the waist support effect provided by the double structure of the rear waist portion, the folded portion has a flared structure relative to the body, which allows the width of the folded portion to move up and down, making it more adaptable to pulling forces in various directions.This allows the bottom clothing to follow the body as posture changes such as bending and straightening the waist and thrusting out the hips, making it less likely for the clothing to shift or turn up at the waist, and further providing the effect of providing a comfortable fit regardless of the wearer's body shape or balance. In addition, the approximately triangular double structure defined by the joining line of the front body where the folded portion is fastened and the fastening portion of the back body has the effect of supporting the wearer's pelvis from both the left and right sides.

[0012] According to the invention of claim 2, the fabric stretches from the back to the front, crossing at the front to double-wrap the abdomen, providing a comfortable fit regardless of body shape or posture, and providing constant support to the abdomen, which changes shape significantly due to breathing movements, etc.

[0013] According to the invention of claim 3, the front hem of the bottom garment is made of raw fabric that does not require edge finishing, which has the effect of preventing the front hem from digging into the groin when the wearer moves, such as squatting, running, etc. In addition, the back hem has a hip-up panel structure that is supported by a double structure, which prevents the front hem from slipping or rolling up when the wearer moves, naturally supports the buttocks from below, and has the effect of preventing unevenness caused by the garment digging into the skin.

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a bottom garment according to the present invention will be described with reference to the drawings.

[0016] [Embodiment 1] FIG. 1 is a rear view of one embodiment of the garment of the present invention. The bottom garment (1) has a folded-back portion (3) folded outward at the top of the back body (2). The folded-back portion (3) has its end (4) fastened to the back body (2) at one fastening point (f1, f2) on each side of the back body, and the folded-back end (4) is configured in a loose structure that is free except for the fastening points (f1, f2). The folded width of the folded portion (3) is preferably about 1 / 5 to 3 / 5 (about 5 cm to 15 cm) of the center back length of the bottom garment (1). In this embodiment, the fastening portions (f1, f2) are sewn over a distance of 0.5 cm to 1.0 cm. Any means can be used as long as they are fastened over a distance of 0.3 cm to 1.5 cm.

[0017] The back waist portion of the bottom garment (1) has a fold line at its upper end, and the end portion (4) of the fold is free except for the fastening portions (f1, f2), which provides support through a double structure, while the width of the fold portion can be adjusted up and down, making it highly adaptable to pulling forces in various directions. With this configuration, the back waist portion of the bottom garment (1) follows the wearer's body without slipping, even when the wearer bends and stretches their waist significantly or squats.

[0018] FIG. 2 is a side view of the bottom garment (1) of FIG. The folded left end (t1) and right end (t2) of the folded portion (3) are joined to the front body (5) on the joining lines (j1, j2) on the left and right sides of the front body (5). The joining means may be any means capable of fastening the ends together along the joining line, such as sewing, fusing, or adhesive.

[0019] FIG. 3 is a front view of the bottom garment (1) of FIG. In this embodiment, two body parts (a) are used, which extend from the back body (2) through the sides to the front to form the front body (5). The parts will be described in detail later using Figure 4, but here we will explain about the front body. The body part (a), which extends from the back body (2) through the sides to the front to become the front body (5), is crossed at the front from both the left and right sides and is configured to overlap and cover the abdomen, and the ends of the body part (a) that extend from the left side to the right side or from the right side to the left side are joined to another body part (a) on joining lines (j1, j2), respectively. The joining means may be any means capable of fastening the ends together along the joining line, such as sewing, fusing, or adhesive.

[0020] The front cross structure, in which two body parts (a) extending from the back body (2) to the front on both sides are layered to wrap around the abdomen, increases flexibility in accommodating abdominal movements caused by the wearer's posture and breathing, and also provides a support effect that always naturally pulls the abdomen up. In addition, the front hem is made of free-cut fabric, which does not require edge processing, so the front hem does not dig into the wearer's groin when they squat or bend forward, allowing them to move with confidence.

[0021] FIG. 4 is an exploded view of the parts of the bottom garment of FIG. 1, and FIG. 5 is an explanatory diagram of joining of the parts. In this embodiment, one bottom garment (1) is produced from two body parts (a), one upper back body part (b), and one or one set of gusset parts (c). The body part (a), upper back body part (b), and gusset part (c) may be made of different fabrics or the same fabric. The body part (a) and upper back body part (b) can be made of elastic fibers that are stretchable in two or more directions, such as having equal stretchability both vertically and horizontally, to achieve a more supportive effect. The stretchability is preferably 140% to 260% vertically and 80% to 140% horizontally, for example. The gusset part (c) may be a single piece, or may be a set consisting of an outer fabric and a lining that is softer against the skin.

[0022] The hem of the back body (2) has a hem cuff (6) that is folded and secured to the inside of the bottom garment (1) to form a hip-up panel structure. The cuff may be secured only at the edge, or the entire surface. The securing method may be selected arbitrarily, such as sewing, welding, or bonding, but since it will be on the inside of the garment, a method that is soft against the skin is preferred.

[0023] 6 is a side view and a rear perspective view of the bottom garment of FIG. 1. FIG. As shown in FIG. 6, the substantially triangular double-structure portion (S) defined by the joining line (j1) and the fastening portion (f1) supports the pelvis from the sides. The pelvis and the gluteus medius muscle that supports the pelvis are supported from the sides by the double structure part (S), which provides a corrective force to the entire waist of the wearer that is wrapped in the bottom clothing (1), thereby providing stability when worn.

[0024] [Embodiment 2] FIG. 7 shows a front view, a rear perspective view, a side view, and a rear view of a bottom garment (11) according to another embodiment of the present invention. In this embodiment, the bottom garment (11) is formed of a front body section, a back body section, and a gusset section, and a folded-up section (13) is provided at the upper part of the back body section of the bottom garment (11). The folded-up end (14) of the folded-up section (13) is folded back and fastened to the back body section of the bottom garment (11) by fastening sections (f11, f12). The folded-up end (14) is configured in a loose structure that is free except for the fastening sections (f11, f12).

[0025] The folded width of the folded portion (13) is preferably about 1 / 5 to 3 / 5 (about 5 cm to 15 cm) of the center back length of the bottom garment (11). In this embodiment, the fastening portions (f11, f12) are sewn to a depth of 0.5 cm to 1.0 cm. Any means can be used as long as they are fastened to a depth of 0.3 cm to 1.5 cm.

[0026] The folded left and right ends of the folded portion (13) are joined on the joining lines (j11, j12) of the front and back body sections of the bottom garment (11). The joining means may be any means capable of fastening the ends together along the joining line, such as sewing, fusing, or adhesive.

[0027] The bottom garment (11) has a fold line at the top of the rear waist portion, and the folded end (14) is free except for the fastening portions (f11, f12), which provides support through a double structure while also increasing flexibility in terms of resistance to pulling forces in various directions. This configuration allows the rear waist portion of the bottom garment (11) to conform to the wearer's body without slipping, even when the wearer bends and stretches their waist significantly or squats.

[0028] [Embodiment 3] FIG. 8 is a rear perspective view of a bottom garment according to yet another embodiment of the present invention. In the embodiment shown in (a), the ends of the folded-over portion at the upper back of the bottom garment are fastened with linear fastening portions (f111, f112) from the left and right folded ends to the left and right sides of the back body. In this embodiment, compared to the bottom garments described in the first and second embodiments, the wearer feels more supported in the waist area while maintaining the conformability and flexibility provided by the flared structure.

[0029] In the embodiments shown in (b) and (c), the bottom garment covers from the waist down to the legs.

[0030] In the embodiment shown in (b), the upper back body part is constructed in two layers, and a cross structure is implemented at the rear waist portion. In this embodiment, the folded-over section is formed so that the left and right folded ends are different lengths, creating a double folded section that is inverted from the left and right, thereby providing greater support for the rear waist area and preventing slipping down, which is a common problem with bottom garments that cover the legs.

[0031] The embodiment shown in (c) is a variation of the bottom garment of embodiment 1, with the hem adjusted to cover the legs. The flared structure of the folded part at the top of the back and the cross structure at the front prevent the bottom garment from slipping down.

[0032] While specific examples of the embodiments have been described above, the bottom garment of the present invention is not limited to these descriptions and can be applied to various forms by devising various component configurations. It will also be obvious to those skilled in the art that various types of bottom garments can be produced by devising various shapes and positions of fastening portions and joining lines. [Industrial Applicability]

[0033] The bottom garment of the present invention has a double-layered back waist section with a folded-over construction, and the folded end is fastened only by a fastening section, while the rest is left loose. This allows the back waist section to follow the wearer's movements and prevent slippage caused by the back waist section being pulled downward, even when squatting, for example. The flared construction also provides flexibility to the garment's shape, ensuring a comfortable fit regardless of changes in body shape due to breathing or posture, or the wearer's physique. Furthermore, by joining the folded left and right ends to the body at the left and right sides of the wearer's front armpits, the fixed, approximately triangular double-layered construction defined by the joining lines and fastening sections supports the pelvis from both sides. This bottom garment provides a comfortable fit due to its adaptability and flexibility, as well as the shaping power of its double-layered construction, without causing discomfort due to tightness or digging in.
