Description

[Technical Field]

[0001] The present invention relates to a lower body garment. [Background technology]

[0002] Conventionally, as described in Patent Document 1, lower-body garments that assist respiratory function and improve respiratory efficiency are known. One example of such garments is a girdle, in which a diamond-shaped piece arranged on the front side of the girdle body covers at least a portion of the rectus abdominis muscle. The primary stretch direction of the diamond-shaped piece is approximately aligned with the muscle fiber direction of the rectus abdominis muscle. A pair of other pieces are arranged diagonally above and to the left and right of the piece, and these pieces cover at least a portion of the external oblique abdominal muscle. The primary stretch direction of this pair of pieces is approximately aligned with the muscle fiber direction of the external oblique abdominal muscle. The above configuration assists the function of the rectus abdominis muscle and the external oblique abdominal muscle, which are muscles that control exhalation.

[0003] On the other hand, the lower-body garment described in Patent Document 2 has a front body with left and right band-like regions that form a roughly V shape, and an upper abdominal region positioned above the band-like regions. These regions tighten the lower abdomen over a wide area, correcting the abdominal silhouette. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-268403 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-144302 Summary of the Invention [Problem to be solved by the invention]

[0005] The garment described in Patent Document 1 focuses on the rectus abdominis and external oblique muscles and has individual pieces covering these muscles, but deformation of the garment during movement reduces the effectiveness of the tightening force provided by the pieces, leaving room for improvement in terms of assisting respiratory function. Furthermore, the garment described in Patent Document 2 is designed to align the abdomen and is therefore not suitable for assisting respiratory function. The inventors discovered that in order to perform effective stretching (for example, stretching that relaxes the body and increases the range of motion of the joints), it is important to activate the abdominal muscles while exhaling deeply and for a long time, and they conducted extensive research into lower-body garments that can achieve this state in the wearer.

[0006] To provide lower body clothing that can accommodate the wearer's posture, activates abdominal muscles, and allows the wearer to easily exhale deeply and completely. [Means for solving the problem]

[0007] [1] A lower-body garment according to one embodiment of the present disclosure comprises a main body portion having a front portion, a back portion, and a crotch portion; and a front patch portion that overlaps the front portion of the main body portion and covers most of a triangular area consisting of portions corresponding to the wearer's pubic symphysis and the left and right anterior superior iliac spines. The front patch portion includes a lower edge that is close to the portion corresponding to the pubic symphysis, a pair of lower edge portions that extend diagonally upward from the lower edge, an upper edge portion that is closest to the waist portion of the main body portion, and a pair of side edge portions that connect the pair of lower edge portions and the upper edge portion, the lower edge being connected to the crotch portion of the main body portion, and the pair of side edge portions being connected to the main body portion at a position on the front, passing near the portions corresponding to the anterior superior iliac spines, and the pair of lower edge portions and upper edge portions being free from the main body portion.

[0008] According to the lower-body garment [1], the front patch covers the wearer's abdomen (corresponding to a triangular region). The lower edge of the front patch and a pair of side edges are connected to the main body. This configuration applies pressure to the wearer's abdomen and crotch area, increasing intra-abdominal pressure during exhalation. The pair of side edges are connected to the main body at a position above the front and do not wrap around to the rear, so that the pressure (pressure) is applied to the wearer's abdomen without escaping rearward. Furthermore, because the pair of lower and upper edges are separated from the main body, the front patch conforms well to the abdomen, maintaining the pressure regardless of the wearer's posture. As a result, the wearer can easily exhale deeply and completely while activating the abdominal muscles (specifically, the internal oblique and transverse abdominis muscles).

[0009] [2] In the lower-body garment described in [1] above, the front cloth portion may include a high-tightening-force portion formed along the front centerline that has a stronger tightening force than other portions. With this configuration, when the lower-body garment is worn, there is no difference in the left and right stretch of the front cloth portion in the vertical and horizontal directions, centered around the high-tightening-force portion formed along the front centerline. In other words, the fabric stretches evenly on both sides of the high-tightening-force portion. This effectively distributes pressure and provides uniform support for the abdomen.

[0010] [3] In the lower-body garment of [1] or [2] above, the front patch portion may be joined to the main body portion at the front center line. With this configuration, when the lower-body garment is worn, the joining portion at the front center serves as a fulcrum, eliminating any left-right difference in the longitudinal and lateral stretch of the front patch portion. In other words, the fabric stretches evenly on both sides of the joining portion. This effectively distributes pressure and provides uniform abdominal support. When this configuration is adopted in the lower-body garment of [2], the high tightening force portion is joined to the main body portion, thereby evenly achieving the above-mentioned functions and effects.

[0011] [4] In the lower-body garment of any one of [1] to [3] above, the front patch portion may be made of fabric that is smaller than the corresponding portion of the front of the main body portion over which the front patch portion is placed. With this configuration, when the lower-body garment is worn, the front patch portion stretches more and fits better around the abdomen. This allows for a fit that accommodates different body shapes and sizes of wearers. [Effects of the Invention]

[0012] According to the present invention, the wearer can easily take a deep, long breath while activating the abdominal muscles. [Brief explanation of the drawings]

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated description will be omitted.

[0015] The basic configuration of pants 1 according to this embodiment will be described with reference to FIG. 1. As shown in FIG. 1, the pants 1 are lower body garments suitable for wearing, for example, while stretching or exercising. A wearer wears the pants 1 by itself (on bare skin), for example. Note that the pants 1 may also be worn over underwear such as shorts by a wearer. The pants 1 are primarily designed for women, but the wearer's gender is not particularly important. Note that FIG. 1 shows the pants 1 laid flat.

[0016] The pants 1 include a main body portion 2 made of a stretchable fabric. The main body portion 2 includes a front portion 3 covering the wearer's abdomen (including the lower abdomen, described later), a back portion 4 covering the wearer's buttocks, a crotch portion 6 (also called a crotch portion), a waist portion 8, and left and right hem portions 7 extending downward from the front portion 3, back portion 4, and crotch portion 6. The waist portion 8 is a portion that covers the wearer's waist and has a height (width) in the vertical direction. As shown in FIG. 1, the waist portion 8 may be attached with a stretchable member such as rubber and be separate from the front portion 3 and back portion 4, or it may be a portion without a stretchable member and have no boundary between the front portion 3 and back portion 4. The front portion 3 and back portion 4 form a tubular shape that fits the wearer's lower body. The wearer's legs are passed through the left and right hem portions 7. The waist portion 8 is positioned, for example, slightly above the wearer's navel, but is not limited thereto. The height (crotch depth) of the waist portion 8 may be set as appropriate. There is also no particular limitation on the length of hem 7. Hem 7 terminates somewhere above the wearer's thigh in the vertical direction. In this specification, the "vertical direction" means the direction of the wearer's height.

[0017] When the pants 1 are laid flat (as shown in FIG. 1), the left and right side edges S, S of the main body 2, which are the boundaries between the front and back portions 3 and 4, are located at the left and right ends. In other words, when the pants 1 are laid flat, only the front portion 3 in the circumferential direction of the main body 2 is visible, and the back portion 4 is not visible.

[0018] The tubular portion consisting of the front portion 3 and the back portion 4 may be configured such that the front body and the back body are joined (for example, sewn) at left and right seam lines, or may be configured such that the front and back body are joined (for example, sewn) at front and back seam lines that pass through the front center and the back center. The tubular portion may be knitted as a single unit and have no seam lines in the circumferential direction.

[0019] The main body 2 is made of, for example, a warp-knitted or weft-knitted fabric extending in the vertical direction (up and down) or horizontal direction (left and right). The stretchable material used for the main body 2 is, if it is a warp-knitted fabric, a material such as two-way raschel, two-way tricot, or two-way satin power net. The stretchable material used for the main body 2 is, if it is a weft-knitted fabric, a material such as a weft-knitted knit such as rib knit, or bare smooth. Fabrics with different stretchability or strength may be used for each part of the main body 2, or the entire main body 2 may be made of the same fabric. The configuration of the main body 2 is not limited to the above configuration. The parts may be joined by sewing, or may be joined by other means such as adhesive.

[0020] Next, the abdominal pressure application structure of the pants 1 will be described. The pressure application structure of the pants 1 has the effect of correcting the abdominal shape, but is also provided to support deep, long breathing by completely exhaling from the abdomen. This type of breathing is not shallow, short breathing that uses shoulder and neck muscles such as the trapezius muscles, but breathing that uses abdominal muscles such as the oblique abdominal muscles and transverse abdominis. Deep, long, complete exhalation creates an autonomic nervous state in which the parasympathetic nervous system is dominant, relaxing the wearer's body. This relaxed state relieves muscle tension, allowing for a wider range of joint motion and enabling ideal stretching. The configuration for achieving this will be described below.

[0021] The pants 1 include a front patch 10 that is substantially V-shaped in front view and is provided so as to overlap the front portion 3 of the main body portion 2. The front patch 10 is made of, for example, a double-layered stretchable fabric. However, the front patch 10 may also be made of a single-layered stretchable fabric. The front patch 10 is attached to the outer surface of the front portion 3 (the side opposite to the skin side). The front patch 10 is attached only to the front portion 3 of the main body portion 2 and does not extend to the back portion 4 (see Figures 2 and 3(a)). When the pants 1 are laid flat, the side edges 12 of the front patch 10 are located at the front portion 3 (the front surface of the pants). Furthermore, when the pants 1 are worn, the side edges 12 of the front patch 10 are also located at the front portion 3 (the front surface of the pants).

[0022] As shown in FIG. 1 , the front patch portion 10 covers most of a triangular region A consisting of the wearer's left and right anterior superior iliac spine corresponding regions Pa and one lower region Pb corresponding to the pubic symphysis. The regions Pa corresponding to the anterior superior iliac spine are the periphery of the wearer's left and right anterior superior iliac spines (surface portion of the body), and the region Pb corresponding to the pubic symphysis is the periphery of the wearer's left and right anterior superior iliac spines (surface portion of the body). "Most of the triangular region A" means, for example, 80% or more of the region A. "Most of the triangular region A" may also be, for example, 90% or more of the region A. In this embodiment, the portion of the region A not covered by the front patch portion 10 is, for example, the valley of the V where the upper edge portion 11 and the front center seam line C (both of which will be described later) intersect.

[0023] The front patch portion 10 is also made of, for example, a warp-knitted or weft-knitted fabric extending in the vertical (up-down) or horizontal (left-right) direction. The stretchable material used for the front patch portion 10 is, for example, a warp-knitted material such as two-way raschel, two-way tricot, or two-way satin power net. The stretchable material used for the front patch portion 10 is, for example, a weft-knitted material such as smooth. The stretchability or strength of the front patch portion 10 may differ from that of the main body portion 2. For example, if the front patch portion 10 has a double structure, the stretchability of the front patch portion 10 is less than that of the main body portion 2 (the front patch portion 10 is less stretchy).

[0024] The front patch portion 10 includes a lower edge 13 adjacent to the pubic symphysis corresponding portion Pb, a pair of left and right lower edge portions 14 extending diagonally upward from the lower edge 13, an upper edge portion 11 closest to the waist portion 8 of the main body portion 2, and a pair of left and right side edge portions 12 connecting the pair of left and right lower edge portions 14 and the upper edge portion 11. The lower edge 13 may be positioned slightly behind the pubic symphysis corresponding portion Pb (toward the rear when viewed from the human body), or may be positioned on the pubic symphysis corresponding portion Pb.

[0025] The front patch portion 10 is made of fabric that is smaller than the corresponding portion of the front portion 3 of the main body portion 2 onto which it is overlaid. For example, as will be described later, the front portion 3 of the main body portion 2 is joined to a pair of side edges 12 of the front patch portion 10, but the left-right distance (length) between the left and right joining portions of the front portion 3 in a flat state before being joined to the front patch portion 10 is greater than the left-right width of the front patch portion 10. Therefore, when the pants 1 are not worn and are laid flat, the front portion 3 of the main body portion 2 is pulled by the front patch portion 10, and the pair of side edges 12 are pulled toward the front center.

[0026] The front patch cloth portion 10 includes a high tightening force portion 18 formed along the front center line. In this embodiment, for example, the front patch cloth portion 10 is made of a double-layered fabric, and the two pieces of fabric are joined together by sewing or the like along the front center line. The area where the two pieces of fabric are joined together forms the high tightening force portion 18, which has a stronger tightening force than the other areas. In the pants 1 of this embodiment, the high tightening force portion 18 (i.e., the area of ​​the front center seam line C) is separated from the main body portion 2.

[0027] As another configuration example, the front patch portion 10 may be made of a single-layer fabric. For example, a separate member such as tape may be attached to the front patch portion 10 made of a single piece of fabric to reinforce it, thereby forming a strong tightening force portion 18 with stronger tightening force than the other portions. Alternatively, the front patch portion 10 may be made of separate left and right pieces of fabric that are sewn together in the center. In this case, the center seam (joining line) becomes the strong tightening force portion 18 with stronger tightening force than the other portions.

[0028] The lower edge 13 of the front patch portion 10 is joined to the crotch portion 6 of the main body portion 2. The lower edge 13 is joined to the main body portion 2 over its entire length, i.e., over the entire area between the left and right lower end points 14b of the pair of lower edge portions 14. The lower edge 13 may be a single straight line or may be curved. The lower edge 13 may also be V-shaped.

[0029] The pair of side edges 12 are connected to the left and right side portions of the front portion 3 of the main body portion 2. As described above, the side edges 12 are located within the front portion 3. The side edges 12 do not overlap the rear portion 4. The pair of side edges 12 pass near the anterior superior iliac spine corresponding portions Pa and extend generally in the up-down direction. Each side edge 12 is located slightly outside the corresponding anterior superior iliac spine corresponding portions Pa in the left-right direction. Depending on the size and body type of the wearer, each side edge 12 may be located on the corresponding anterior superior iliac spine corresponding portions Pa, or may be located slightly inside the corresponding anterior superior iliac spine corresponding portions Pa in the left-right direction. Each side edge 12 is connected to the main body portion 2 along its entire length, i.e., over the entire area between each end 11a of the upper edge 11 and the upper end point 14a of each lower edge 14. The front cloth portion 10 is joined to the main body portion 2 only at the lower edge 13 and the pair of side edges 12. These may be joined by, for example, sewing, or by other means such as adhesion.

[0030] Furthermore, in the pants 1 of this embodiment, the pair of lower edge portions 14 are free from the main body portion 2. For example, the lower edge portions 14 are free from the main body portion 2 over their entire length, that is, over the entire area between the lower end point 14b and the upper end point 14a. Because the lower edge portions 14 are not joined to the main body portion 2 (because they are unjoined portions), they can move freely relative to the main body portion 2.

[0031] The upper edge portion 11 is free from the main body portion 2. The entire length of the upper edge portion 11 is free from the main body portion 2. Since the upper edge portion 11 is not connected to the main body portion 2 (since it is an unconnected portion), it is freely movable relative to the main body portion 2.

[0032] The effects of wearing the pants 1 will be described with reference to FIGS. 2, 3(a), and 3(b). As shown in FIG. 3(a), the front panel 10 provides a kickback effect in the circumferential direction. This kickback effect exerts external pressure on the wearer X's abdomen (see arrow F), as shown in FIG. 3(b) , causing the abdomen to collapse. Furthermore, the front panel 10 and the crotch 6 are pulled up, exerting pressure on the crotch area (around the pubic symphysis Pb) (see arrow B). Just as the transverse abdominis, oblique abdominal muscles, and pelvic floor muscles contract when exhaling deeply and deeply, the abdominal muscles contract, and the abdominal collapse occurs when these pressures are applied to the lower body of the wearer X. Furthermore, the pressure applied to the crotch area increases intra-abdominal pressure, which acts to push up the diaphragm. As a result, the wearer can effectively use the abdomen to breathe. More specifically, this abdominal breathing allows the wearer to exhale deeply, for a longer period of time, and to inhale deeply, for a longer period of time. Even for people who have weak abdominal muscles and have difficulty breathing (for example, people who cannot exhale completely), wearing Pants 1 provides abdominal support, allowing for the ideal breathing described above.

[0033] As described above, according to the pants 1 of this embodiment, the front patch 10 covers the wearer's abdomen (corresponding to triangular region A). The lower edge 13 and a pair of side edges 12 of the front patch 10 are connected to the main body 2. This configuration applies pressure to the abdomen and crotch area of ​​the wearer X, increasing intra-abdominal pressure during exhalation. Because the pair of side edges 12 are connected to the main body 2 at a position above the front section 3 and do not extend around the rear section 4, the pressure (pressure) is applied to the wearer's abdomen without escaping backward (see arrow F in FIG. 3(b)). If the pressure were to escape backward, the pressure would be concentrated at the point of maximum circumferential curvature of the lower body within the area covered by the front patch, reducing the pressure on the abdomen and preventing the pants from achieving their intended effect. This does not occur with the pants 1 of this embodiment, and the pressure (pressure) is applied to the wearer's abdomen. Furthermore, because the pair of lower edge portions 14 and upper edge portion 11 are separated from the main body portion 2, the front cloth portion 10 conforms well to the abdomen, and the pressure continues to be applied no matter what posture the wearer X assumes. As a result, the wearer X can easily take a deep, long, complete exhale while activating the abdominal muscles (specifically, the internal oblique abdominal muscles and transverse abdominal muscles).

[0034] The front cloth portion 10 includes a high tightening force portion 18 formed along the front center line. As a result, when the pants 1 are worn, there is no difference between the left and right sides in the vertical and horizontal stretch of the front cloth portion 10, with the high tightening force portion 18 as the center. In other words, the fabric stretches evenly on both sides of the high tightening force portion 18. This effectively distributes pressure and provides uniform support for the abdomen.

[0035] The front patch portion 10 is made of a fabric that is smaller than the corresponding portion of the front part 3 of the main body portion 2 onto which it is overlaid. This allows the front patch portion 10 to stretch more when the pants 1 are worn, providing a better fit to the wearer's abdomen. This allows for a better fit that accommodates different body shapes and sizes of wearers.

[0036] The inventors have confirmed that differences in breathing patterns among the same subjects affect abdominal muscle activity. When subjects took deep, long breaths while focusing on their abdomen, muscle activity in the internal oblique muscles increased by more than 1.3 times compared to when subjects breathed without focusing on their abdomen. Furthermore, when subjects took deep, long breaths while focusing on their abdomen, muscle activity in the upper trapezius muscles decreased by more than half compared to when subjects breathed without focusing on their abdomen. As mentioned above, the internal oblique muscles are abdominal muscles that contribute to breathing. Breathing while focusing on the abdomen actually increased muscle activity in the internal oblique muscles. The trapezius muscles are muscles that work when the body is stiff (not relaxed). In other words, breathing while focusing on the abdomen resulted in abdominal muscle activity being dominant.

[0037] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, in the above embodiments, the high tightening force portion 18 (the portion of the front center seam C) was detached from the main body portion 2, but the front patch cloth portion 10 may be connected to the main body portion 2 at the high tightening force portion 18. In both the configuration example in which the front patch cloth portion 10 is made of a double-layered fabric and the configuration example in which the front patch cloth portion 10 is made of a single-layered fabric, as described in the above embodiments, the high tightening force portion 18 may be connected to the main body portion 2. Even in this case, the left extending portion 11L and the right extending portion 11R of the upper edge portion 11 are each detached from the main body portion 2 over the entire area between the left and right end portions 11a and the upper end Ca of the front center seam C. Because the left extending portion 11L and the right extending portion 11R are not attached to the main body portion 2 (because they are unattached portions), they can move freely relative to the main body portion 2. According to this configuration, the action and effect of the strong tightening force portion 18 (the effect of the fabric stretching evenly on both sides, dispersing pressure and supporting the abdomen evenly) is more effectively achieved.

[0038] Furthermore, the high tightening force portion 18 does not have to be provided. A seam structure does not have to be provided at the front center position, and reinforcing tape or the like does not have to be provided. The front patch portion 10, which does not include the high tightening force portion 18, may be separated from the main body portion 2 at the front center.

[0039] The left and right hem portions 7 may be omitted from the main body portion 2. In that case, the lower ends of the front portion 3 and the rear portion 4 and the crotch portion 6 form the left and right leg openings.

[0040] (Test example) The inventors tested the effects of pants 1 (pants according to the Example) having the same configuration as the above-described embodiment on the same subject. The pants according to the Comparative Example lack a front panel 10. Figures 4(a) to 4(c) are diagrams illustrating various stretching movements and measurement areas according to the Test Example. Figures 5, 6, and 7 show the angles or openings of specific body parts when subjects wearing each pair of pants performed various stretching movements. In the test shown in Figures 4(a) and 5, the subject performed a stretching exercise in which both elbows were raised and bent to the side, followed by a twisting motion. The shoulder joint angle (angle α shown in Figure 4(a)) on the side of the body where the elbows were raised was measured. As shown in Figure 5, the measurement was 201 degrees when wearing the pants according to the Comparative Example, while it was 206 degrees when wearing the pants according to the Example. In this test, 10 subjects were instructed to take deep, long breaths. The data shown in Figure 5 is the average value obtained from the test on these 10 subjects.

[0041] In the test shown in Figures 4(b) and 5, subjects performed a stretching exercise in which they stepped forward with one foot, lowered their hips, and placed the knee of the remaining leg on the floor. The distance from the heel of the stepped leg to the grounded knee (hip joint extension; length L shown in Figure 4(b)) was measured. As shown in Figure 5, the distance was 67 cm when wearing the pants of the comparative example, while it was 70 cm when wearing the pants of the example. In this test, seven subjects were instructed to take deep, long breaths. The data shown in Figure 5 is the average value obtained from the test on these seven subjects.

[0042] In the test shown in Figures 4(c) and 7, the test subject was asked to stretch by hugging one knee while lying on his back, and the hip joint angle (angle β shown in Figure 4(c)) of the stretched leg (the leg not being hugged) was measured. As shown in Figure 7, when wearing the pants according to the comparative example, the angle was 144 degrees, while when wearing the pants according to the example, the angle was 148 degrees. In this test, eight test subjects were instructed to take deep, long breaths. The data shown in Figure 7 is the average value obtained from the test on these eight subjects.

[0043] As can be seen from all of the stretch tests above, when the pants according to the examples were worn, a wider joint angle was achieved, suggesting that stretching was performed more effectively. [Explanation of symbols]
