Description

[Technical Field]

[0001] The present invention relates to a garment for lower legs, and more particularly to a garment for lower legs having a recessed portion recessed downward in the upper central portion of the front and back portions of the waist top. [Background technology]

[0002] Shapewear for maintaining a beautiful figure has been proposed for some time. For example, Patent Document 1 discloses shapewear that uses a slimming fabric to create a balanced figure. Patent Document 2 discloses shapewear that, when used as a girdle or the like, can maintain its shape without needing to be removed when using the toilet. Furthermore, Patent Document 3 discloses shapewear that shapes the abdomen, waist, hips, and bust. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2010-65371 [Patent Document 2] Patent Publication No. 2008-25070 [Patent Document 3] Japanese Patent Application Publication No. 8-209404 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in recent years, it has become clear that a forward tilt of the pelvis, which causes arching of the lower back, can have adverse effects on various parts of the body. For this reason, there has been a demand for the development of shapewear that can correct the forward tilt of the pelvis, maintain proper posture, and eliminate arching of the lower back.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide clothing for the lower limbs that allows the forward tilted pelvis to be straightened, thereby maintaining correct posture and eliminating arched lower back. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the invention of claim 1 relating to lower limb clothing is a lower limb clothing having a waist top and a body part, characterized in that a recessed portion that is recessed downward is provided at the upper part of the central part of the back of the waist top.

[0007] According to the present invention, the upper part of the center of the rear part of the lumbar support has a recessed portion that is recessed downward, so that the center of the front part of the lumbar support is pushed up from below, and the center of the rear part of the lumbar support is pushed down from above. This allows the lumbar region to be corrected by pulling it downward and rearward, which makes it possible to straighten the pelvis that has tilted forward, maintain correct posture, and eliminate arched lower back.

[0008] If the upper edge of the front part of the waist top section is configured to be positioned above the navel of the human body when attached to the human body, the part above the navel of the human body will be pulled downward and behind the waist, making it possible to straighten the forward-tilted pelvis.

[0009] If the upper edge of the front part of the waist top section is configured to be positioned between the third and fourth lumbar vertebrae of the human body when attached to the human body, the excessive lumbar forearm that has been strengthened by the forward tilt of the pelvis can be corrected so that it approaches the normal lumbar forearm, making it possible to straighten the forward tilted pelvis.

[0010] If the upper edge of the front part of the waist top section is configured to be positioned between the lower part of the third lumbar vertebra and the upper part of the fourth lumbar vertebra when attached to the human body, it is possible to correct the excessive lumbar forearm that has been strengthened by the forward tilt of the pelvis so that it is closer to the normal lumbar forearm, and it is possible to straighten the forward tilted pelvis.

[0011] If the lower end of the rear recess is configured to be located between the lower part of the fourth lumbar vertebra and the upper part of the sacrum when the support is worn on the human body, excessive lumbar forearms that have been strengthened by anterior tilt of the pelvis can be corrected to be closer to normal lumbar forearms.

[0012] If the lower end of the rear recess is configured to be positioned between the intervertebral disc adjacent above the fifth lumbar vertebra and the intervertebral disc adjacent below the fifth lumbar vertebra when the support is worn on the body, excessive lumbar forearms that have been aggravated by anterior pelvic tilt can be corrected to be closer to normal lumbar forearms.

[0013] When worn on the human body, the upper edge of the front of the waist top portion can be positioned between the third and fourth lumbar vertebrae of the human body, and the lower end of the rear recess can be configured to be positioned between the lower part of the fourth lumbar vertebra and the upper part of the sacrum of the human body.

[0014] More specifically, when worn on a human body, when the front upper edge of the waist top portion is positioned between the lower part of the third lumbar vertebra and the upper part of the fourth lumbar vertebra of the human body, the lower end of the rear recess portion can be configured to be positioned between the intervertebral disc adjacent above the fifth lumbar vertebra of the human body and the intervertebral disc adjacent below the fifth lumbar vertebra of the human body.

[0015] If the depth dimension of the rear recess is set to 4 to 13 cm, the lower end of the rear recess can be positioned below the fifth lumbar vertebra of the human body when worn on the human body.

[0016] The rear recess is formed in a V-shape, and the angle of the mutually opposing inclined lines of the V-shape is set to 15° to 45° with respect to the horizontal, so that the inclined lines can act to naturally straighten the pelvis, which has tilted forward. By increasing the ratio of the radius of curvature of the curve connecting the tip of the spinous process of the first lumbar vertebra to the tip of the spinous process of the fifth lumbar vertebra before the device is attached to the human body from 1.3 to 2.5, the forward-tilted pelvis can be straightened without any strain.

[0017] The upper edge of the body portion is connected to the lower edge of the waist top portion, and is made of stretchable fabric. If the stretch direction includes a direction that slopes downward toward the center of the back, it is possible to further correct the waist by pulling it downward and to the rear.

[0018] A belt-like pelvic belt portion that wraps around the pelvis and encircles the upper part of the body portion can be provided on top of the body portion.

[0019] The pelvic belt portion is made of a stretchable fabric, and the stretch direction of the pelvic belt portion includes a direction that slopes downward toward the center of the rear, and this direction overlaps with the stretch direction of the left body portion and the right body portion, making it possible to further correct the waist by pulling it downward and rearward.

[0020] By providing a downwardly recessed portion at the upper center of the front part of the waist top, it becomes possible to apply stress to the front recessed portion while pulling the waist further downward and rearward at the rear part of the waist top, thereby improving the effectiveness of waist correction.

[0021] If the depth dimension of the recessed portion at the rear of the waist top is set to be greater than the depth dimension of the recessed portion at the front of the waist top, the waist can be reliably corrected.

[0022] If the depth dimension of the depression in the front portion is set to 0.1 to 1 cm, the effect of correcting the lower back can be increased.

[0023] The front depression is formed in a V-shape, and the angle of the opposing inclined lines of the V-shape is set to 0.5° to 5° with respect to the horizontal direction, thereby further increasing the effect of correcting the lower back.

[0024] The waist top section has a front waist top section at the front, a left waist top section extending from the left side to the rear, and a right waist top section extending from the right side to the rear, and the front waist top section is made of at least two pieces of fabric overlapping each other front and back while tilting downward to form the depression in the front, and the upper edge of the overlapping front and rear sections is disconnected from the opposing fabric, which allows the disconnected front section to shift according to the body shape when worn, improving the fit. Also, the disconnected front section prevents excessive tightness, improving comfort.

[0025] The left hip top section is made of fabric that slopes downward from the left side toward the center of the rear, and the right hip top section is made of fabric that slopes downward from the right side toward the center of the rear, and the ends of the left hip top section and the right hip top section are overlapped front to back so as to intersect with each other to form the recessed portion in the rear, and the upper edge of the overlapping front and rear sections is not connected to the opposing fabric, which allows the unconnected rear section to shift according to the body shape when worn, improving the fit and preventing excessive tightness and improving comfort.

[0026] If the length of the non-connected portion in the front is set to 10 to 30 cm, it is possible to reliably improve the fit and comfort when wearing the shoes.

[0027] If the non-connected portion in the front part is formed across the entire area in the left-right direction of the front waist top part, the fit and comfort can be further improved.

[0028] If the ratio of the left-right length of the unconnected portion in the front to the left-right length of the unconnected portion in the rear is set to 5 to 20, the fit and comfort can be further improved.

[0029] The body portion is formed by overlapping multiple stretchable stretch fabrics, and includes a portion where one stretch fabric stretches in one direction sloping downward toward the center of the back portion and other stretch fabrics stretch in two intersecting directions. This increases the stretch force of the one stretch fabric that stretches in one direction, making it possible to further correct the waist by pulling it downward, while the other stretch fabric that stretches in two directions makes it easier to stretch according to the body shape, improving the fit. The other stretch fabric that stretches in two directions also prevents excessive tightness, improving comfort.

[0030] The leg insertion openings are connected to the leg insertion parts, and the leg insertion parts extend downward from the leg insertion openings and are made of a stretchable fabric with a vertical dimension of 2 to 10 cm, so that the force applied to the leg insertion openings during waist adjustment can be dispersed to the leg insertion parts, thereby alleviating excessive tightness at the leg insertion openings and improving comfort. The force generated when the lower end of the front depression at the front of the waist ceiling is stretched by a unit length is greater than the force generated when the lower end of the rear depression is stretched by a unit length at a front position that is at the same position in the vertical direction as the lower end of the rear depression, and the force generated when the lower end of the rear depression is stretched by a unit length is greater than the force generated when the lower end of the rear depression is stretched by a unit length at a front position that is at the same position in the vertical direction as the lower end of the rear depression, and further, the force generated when the lower end of the rear depression is stretched by a unit length is greater than the force generated when the lower end of the front depression at the front of the waist ceiling is stretched by a unit length, making it possible to straighten a tilted pelvis, maintain correct posture, and eliminate arching of the lower back. [Effects of the Invention]

[0031] According to the present invention, it is possible to straighten the forward tilted pelvis, maintain correct posture, and eliminate arched lower back. [Brief explanation of the drawings]

In the following description, front, back, left, right, and top and bottom are defined as viewed from the front side when the lower limb garment 1 is worn by the human body 100, and each direction is indicated in the drawings.

[0034] Referring to Figures 1 to 4, the outline of the lower limb clothing 1 of this embodiment will be explained. The lower limb clothing 1 has a waist top portion 10, a body portion 20, a pelvic belt portion 30, and a crotch portion 40, and has a leg insertion opening 50 at the lower end through which the leg portion 101 of the human body 100 is inserted.

[0035] The waist top 10 is arranged in a band-like manner around the waist 102 of the human body 100, and has a V-shaped rear depression 11 (hereinafter referred to as the rear depression 11) and a front depression 12 (hereinafter referred to as the front depression 12).

[0036] The rear recess 11 is recessed downward from the upper central portion of the rear of the waist top portion 10, specifically at the upper end portion. The rear recess 11 has a vertical depth dimension X of 4 to 13 cm. The angle α of the mutually opposing V-shaped inclined lines 11a of the rear recess 11 is 15 to 45 degrees with respect to the horizontal. The upper edge 11d of the lower end 11c of the rear recess 11 is configured to be located between the lower part of the fourth lumbar vertebra 100D and the upper part of the sacrum 100F of the human body 100 when the seat belt is worn on the human body 100. More specifically, the upper edge 11d of the lower end 11c of the rear recess 11 is configured to be located between the intervertebral disc 100E' adjacent above the fifth lumbar vertebra 100E of the human body 100 and the intervertebral disc 100F' adjacent below the fifth lumbar vertebra 100E when the seat belt is worn on the human body 100.

[0037] The vertical depth dimension X of the rear recessed portion 11 is set to be larger than the vertical depth dimension Y of the front recessed portion 12.

[0038] The front recess 12 is recessed downward from the upper central portion of the front of the waist ceiling part 10, more specifically, at the upper end. The front recess 12 has a vertical depth Y of 0.1 to 1 cm, and is slightly recessed downward. The V-shaped, mutually opposing inclined lines 12a of the front recess are slightly inclined, with an angle β of 0.5° to 5° with respect to the horizontal. The upper edge 10A' of the front of the waist ceiling part 10, more specifically, the upper edge 10A' of the lower end 12c of the front recess 12, is configured to be located above the navel of the human body 100 when worn on the human body 100.

[0039] That is, the upper edge 10A' of the front part of the waist top portion 10, i.e., the upper edge 10A' of the lower end portion 12c of the front depression portion 12, is configured to be positioned between the third lumbar vertebra 100C and the fourth lumbar vertebra 100D of the human body 100 when worn on the human body 100.

[0040] More specifically, the upper edge 10A' of the front of the waist top portion 10, i.e., the upper edge 10A' of the lower end portion 12c of the front recess portion 12, is configured to be positioned between the lower part of the third lumbar vertebra 100C and the upper part of the fourth lumbar vertebra 100D of the human body 100 when worn on the human body 100.

[0041] In other words, in this embodiment, when worn on the human body 100, when the upper end edge 10A' of the front part of the waist top portion 10 is positioned between the third lumbar vertebra 100C and the fourth lumbar vertebra 100D of the human body 100, the upper end edge 11d of the lower end portion 11c of the posterior depression portion 11 is configured to be positioned between the lower part of the fourth lumbar vertebra 100D of the human body 100 and the upper part of the sacrum 100F.

[0042] More specifically, in this embodiment, when worn on the human body 100, when the upper end edge 10A' of the front part of the waist top portion 100 is positioned between the lower part of the third lumbar vertebra 100C of the human body 100 and the upper part of the fourth lumbar vertebra 100D, the upper end edge 11d of the lower end portion 11c of the posterior depression portion 11 is configured to be positioned between the intervertebral disc 100E' adjacent above the fifth lumbar vertebra 100E of the human body 100 and the intervertebral disc 100F' adjacent below the fifth lumbar vertebra 100E.

[0043] Here, as shown in Figures 5 to 9, the waist top portion 10 is formed in a belt-like shape by folding back fabrics 10a1'', 10a2'', 10b'', and 10c'', which are fabrics 10a1, 10a2, 10b, and 10c overlapped by folding back fabrics 10a1, 10a2, 10b, and 10c through folded back portions 10a1', 10a2', 10b', and 10c'.

[0044] The waist top portion 10 is configured so that the folded portions 10a1', 10a2', 10b', and 10c' of the folded fabrics 10a1'', 10a2'', 10b'', and 10c'' are the upper end portions.

[0045] The depressions 11 and 12 can be formed by overlapping a plurality of folded fabrics 10a1'', 10a2'', 10b'', and 10c'' front to back so that they intersect with each other while inclining downwards toward the positions where the depressions 11 and 12 are to be formed.

[0046] More specifically, the waist top portion 10 has a front waist top portion 10A, a left waist top portion 10B, and a right waist top portion 10C, with the front waist top portion 10A being located at the front, the left waist top portion 10B being located from the left side to the rear, and the right waist top portion 10C being located from the right side to the rear.

[0047] That is, the front waist top portion 10A forms the front depression 12 by overlapping two folded pieces of fabric 10a1'', 10a2'' front and back so that they intersect each other while slanting downward in opposite directions toward the position where the front depression 12 is to be formed.

[0048] Here, the upper edge portions 10A' of the front and back overlapping portions of the front waist top portion 10A are not sewn to the opposing fabrics 10a1'', 10a2'', and are therefore not connected to each other. In other words, the opposing fabrics 10a1'', 10a2'' of the front waist top portion 10A can be separated from each other at the upper edge portions 10A' of the front and back overlapping portions. The length of the unconnected portion in the front is 10 to 30 cm. The unconnected portion in the front is formed across the entire width of the front waist top portion 10A.

[0049] The left waist top portion 10B is provided with a single folded fabric 10b'' that slopes downward from the left side toward the center of the rear portion where the rear recess 11 is formed. The right waist top portion 10C is arranged in the opposite direction to the left waist top portion 10B, with a single folded fabric 10c'' sloping downward from the right side toward the center of the rear where the rear depression 11 is formed.

[0050] In other words, the end 10B' of the left hip top portion 10B and the end 10C' of the right hip top portion 10C are overlapped front to back so as to intersect with each other at the center of the rear portion, forming the rear depression 11. The left hip top portion 10B and the right hip top portion 10C are not connected to each other at the upper edge portions 10B'', 10C'' of the overlapping front and rear portions, respectively, as they are not sewn to the opposing fabrics 10b'', 10c'', respectively. In other words, the left hip top portion 10B and the right hip top portion 10C are able to separate the opposing fabrics 10b'', 10c'' at the upper edge portions 10B'', 10C'' of the overlapping front and rear portions. The ratio of the left-right length L1 of the unconnected portion at the front to the left-right length L2 of the unconnected portion at the rear (the left-right length L2 of the unconnected portion of either the left hip top portion 10B or the right hip top portion 10C) is 5 to 20.

[0051] The folded fabrics 10a1'', 10a2'', 10b'', and 10c'' (fabrics 10a1, 10a2, 10b, and 10c) of the waist top portion 10 can be made of a stretchable fabric. This stretchable fabric can be made of polyurethane fiber.

[0052] The stretch fabric (folded fabrics 10a1'', 10a2'', 10b'', 10c'') in this waist top portion 10 can be mesh fabric, and the mesh fabric can be power net. In addition, the stretch fabric can be 1-way fabric that stretches in one direction.

[0053] The stretch direction of the folded fabrics 10a1'', 10a2'', 10b'', and 10c'' in the front depression 12 and the back depression 11 is a direction that follows the slope of the waist top 10, as shown by the dotted arrow in the figure, and can be a direction that intersects with each other at the overlapping parts.

[0054] The waist top portion 10 can be arranged so that a linear or strip-shaped piece of fabric 10d is sandwiched inside the folded fabrics 10a1", 10a2", 10b", 10c", more specifically, inside the folded portions 10a1", 10a2", 10b", 10c" at the upper end (more specifically, the fabric 10d is arranged so that it is sandwiched inside the folded portions 10a1", 10a2", 10b", 10c" at the upper end, and is fixed to the inside of the fabric on the body side by stitching).

[0055] The linear or strip-shaped fabric 10d can be a stretchable fabric, which can be made of polyurethane fiber. The stretch direction can be the same as the stretch direction of the waist top 10, as shown by the dashed arrow in the figure.

[0056] The stretchable fabric (fabric 10d) may be a one-way fabric that stretches in one direction. The stretchable fabric may be a stretch fabric, and the stretch fabric may be a stretch tape. The stretchable fabric, more specifically, the stretch tape, is sandwiched inside the folded portions 10a1′, 10a2′, 10b′, and 10c′, so that it does not dig into the human body 100 as much.

[0057] 10 to 13, the body portion 20 has a front body portion 20A, a left body portion 20B, and a right body portion 20C. The front body portion 20A is provided at the front of the body portion 20, the left body portion 20B is provided from the left side of the body portion 20 to the center of the back, and the right body portion 20C is provided from the right side to the center of the back.

[0058] The body portion 20 is formed by overlapping multiple pieces of stretchable stretch fabric. The body portion 20 is formed from stretchable stretch fabric, and the stretch direction includes a direction along the direction sloping downward toward the center of the back portion. More specifically, the body portion 20 includes a portion where the stretch direction of one of the overlapping stretch fabrics is one direction along the direction sloping downward toward the center of the back portion, or one vertical direction. Even more specifically, the body portion 20 includes a portion where the stretch direction of another of the overlapping stretch fabrics is in two mutually intersecting directions (for example, two directions including the horizontal and vertical directions). The body portion 20 has a front body portion 20A, a left body portion 20B, and a right body portion 20C, which are configured as follows.

[0059] As shown in Fig. 10, the front body portion 20A has a first front body portion 20A1 (Fig. 10(a)), a second front body portion 20A2 (Fig. 10(b)), and a third front body portion 20A3 (Fig. 10(c)), and the first front body portion 20A1, the second front body portion 20A2, and the third front body portion 20A3 are all the same shape. The front body portion 20A is configured by overlapping the first front body portion 20A1 as the outer fabric, the second front body portion 20A2 as the inner fabric, and the third front body portion 20A3 as the intermediate fabric sandwiched between the outer and inner fabrics, with the first front body portion 20A1, the second front body portion 20A2, and the third front body portion 20A3 being positioned in the same order (Fig. 10(d)).

[0060] The front body portion 20A has a top side 20a1, side sides 20a2 and 20a3, and a bottom side 20a4. The side sides 20a2 and 20a3 each have a left side 20a2 and a right side 20a3.

[0061] That is, the top side 20a1 is a curved line that protrudes downward and curves in an arc shape.

[0096] As shown in Figure 14(a), the pelvic belt portion 30 has a belt-like configuration, and more specifically, it has a belt-like configuration that wraps around the pelvis on the upper side of the body portion 20, and is further overlapped on top of the body portion 20 as shown in Figures 14(b) and 15.

[0097] More specifically, the pelvic belt portion 30 is provided on the upper side of the back surface of the body portion 20, and has a front pelvic belt portion 30A, a left pelvic belt portion 30B, and a right pelvic belt portion 30C.

[0098] The front pelvic belt 30A is provided at the front of the pelvic belt 30 and overlaps the upper part of the back surface of the front body 20A.

[0099] The pelvic belt portion 30 may be made of a stretchable fabric, which may be made of polyurethane fiber. The stretchable fabric may be a one-way fabric that stretches in one direction. The stretch direction of the pelvic belt portion 30 includes a direction that slopes downward toward the center of the back, as shown by the dashed arrow in the figure, and this direction (the direction that slopes downward toward the center of the back) may overlap with the stretch direction of the left body portion 20B and the right body portion 20C.

[0100] More specifically, the stretch direction of the front pelvic belt portion 30A is the horizontal (side) stretch direction, which overlaps with the horizontal (side) stretch direction of the front body portion 20A, as shown by the dashed-dotted arrow in the figure. The stretch direction of the left pelvic belt portion 30B is the direction sloping downward toward the center of the back so as to follow the slope of the left hip top portion 10B, as shown by the dashed-dotted arrow in the figure, and overlaps with the stretch direction of the left body portion 20B. The stretch direction of the right pelvic belt portion 30C is the direction sloping downward toward the center of the back so as to follow the slope of the right hip top portion 10C, as shown by the dashed-dotted arrow in the figure, and overlaps with the stretch direction of the right body portion 20C.

[0101] The stretch fabric may be made of polyurethane fiber. The stretch fabric may be a mesh fabric, and the mesh fabric may be a power net.

[0102] As shown in Fig. 16, the crotch section 40 is provided to extend in the front-to-rear direction so as to correspond to the crotch area of ​​the human body 100. The crotch section 40 has a first crotch section 41 (Fig. 16(a)) and a second crotch section 42 (Fig. 16(b)), and the second crotch section 42 has the same shape as the first crotch section 41. The crotch section 40 is configured such that the first crotch section 41 is the outer fabric and the first crotch section 42 is the inner fabric, with the first crotch section and the second crotch section overlapping each other so that their positions are aligned (Fig. 16(c)).

[0103] The crotch section 40 has a front edge 40a, a first side edge 40b, a second side edge 40c, and a rear edge 40d.

[0104] The front edge 40a is a curved line that protrudes forward and curves in an arc. The first side edge 40b and the second side edge 40c are curved lines that protrude inward and curve in an arc so that the distance between them gradually increases from the front to the rear. The rear edge 40d is a curved line that protrudes backward and curves in an arc.

[0105] The front edge 40a is connected to the bottom edge 20a4 of the front body portion 20A, the first side edge 40b and the second side edge 40c, together with the first bottom edges 20b14', 20b24', 20c14', 20c24' and second bottom edges 20b14'', 20b24'', 20c14'', 20c24'' of the left body portion 20B and the right body portion 20C, form a leg insertion opening 50, and the rear edge 40d is connected to the third bottom edges 20b14'''', 20b24'''', 20c14'''', 20c24'''' of the left body portion 20B and the right body portion 20C.

[0106] First crotch section 41 and second crotch section 42 may be made of a stretchable fabric. The stretchable fabric of first crotch section 41 may be made of a two-way tricot fabric formed by tricot knitting. The stretch directions of first crotch portion 41 are horizontal (sideways) and vertical (up and down) as shown by the dashed arrows in the figure, and the stretch directions intersect at right angles.

[0107] The stretch fabric of second crotch region 42 can be a one-way fabric that stretches in one direction. First crotch region 41 stretches in the horizontal direction (sideways) as shown by the dashed arrow in the figure.

[0108] The stretch fabric of the second crotch area 42, i.e., the stretch fabric of the lining, can be a cotton blend fabric (plain stitch knit). By using a cotton blend fabric for the lining, it is possible to provide an excellent feel against the skin. The cotton blend fabric can be a fabric made by blending cotton and polyester fibers.

[0109] As is clear from the above, the crotch region 40 is formed by overlapping multiple layers of stretchable stretch fabric. In the crotch region 40, the stretch direction of one layer of stretchable fabric is the horizontal direction. In addition, the stretch directions of the other layers of stretchable fabric in the crotch region 40 are two mutually intersecting directions.

[0110] The leg insertion openings 50 are provided to correspond to the bases of the legs 101 of the human body 100. The leg insertion openings 50 can be formed to be surrounded by the first lower edges 20b14', 20b24', 20c14', 20c24' and second lower edges 20b14'' and 20c14'' of the left body portion 20B and the right body portion 20C, and the first side edge 40b and second side edge 40c of the crotch portion 40.

[0111] The leg insertion opening 50 is connected to the leg insertion section 60. The leg insertion section 60 extends downward from the leg insertion opening 50. The leg insertion section 60 has a vertical dimension of 2 to 10 cm and is made of a stretchable fabric.

[0112] The stretchable fabric of the leg insertion portion 60 may be made of polyurethane fiber. The stretchable fabric of the leg insertion portion 60 may be a stretch fabric. The stretch fabric may be stretch lace. The stretchable fabric of the leg insertion portion 60 may be a 1-way fabric that stretches in one direction.

[0113] As explained above, according to the present invention, the upper part of the central rear part of the lumbar support part 10 has a recessed part 11 that recesses downward, so that it is possible to correct the posture by pushing upward from below at the central front part of the lumbar support part 10, and by pushing downward from above along the sacrum at the central rear part of the lumbar support part 10. This makes it possible to correct the posture by pulling the lumbar part 102 of the human body 100 downward and rearward, thereby raising the pelvis that has tilted forward, maintaining correct posture, and eliminating arched lower back (Fig. 17).

[0114] Furthermore, the upper edge 10A' at the front of the waist top 10 is positioned above the navel of the human body 100 when attached to the human body 100, so that the side above the navel of the human body 100 is pulled downward and behind the waist 102, making it possible to straighten the pelvis that has tilted forward.

[0115] Furthermore, the upper edge 10A' of the front of the waist top portion 10 is configured to be located between the third lumbar vertebra 100C and the fourth lumbar vertebra 100D of the human body 100 when attached to the human body 100. More specifically, it is configured to be located between the lower part of the third lumbar vertebra 100C and the upper part of the fourth lumbar vertebra 100D of the human body 100 when attached to the human body 100. This makes it possible to correct excessive lumbar forearms that have been strengthened by the forward tilt of the pelvis so that they are closer to normal lumbar forearms, and to straighten the forward-tilted pelvis.

[0116] Furthermore, the upper edge 11d of the lower end 11c of the posterior recess 11 is configured to be located between the lower part of the fourth lumbar vertebra 100D of the human body 100 and the upper part of the sacrum 100F when the human body 100 is worn.More specifically, it is configured to be located between the intervertebral disc 100E' adjacent above the fifth lumbar vertebra 100E of the human body 100 and the intervertebral disc 100F' adjacent below the fifth lumbar vertebra 100E when the human body 100 is worn.This makes it possible to correct excessive lumbar forearms that have been strengthened by anterior pelvic tilt so that they are closer to normal lumbar forearms.

[0117] Furthermore, the depth dimension X of the rear recess 11 is set to 4 to 13 cm, so that the upper edge 11d of the lower end 11c of the rear recess 11 can be positioned below the fifth lumbar vertebra of the human body 100 when the device is worn on the human body 100.

[0118] In addition, the rear recess 11 is formed in a V-shape, and the angle α of the mutually opposing inclined lines 11a of the V-shape is set to 15° to 45° with respect to the horizontal direction, so that the inclined lines 11a act to naturally straighten the pelvis that has tilted forward.

[0119] Furthermore, the body portion 20 is formed from a stretchable stretch fabric, and the stretch direction includes a direction that slopes downward toward the center of the back, so it is possible to further correct the waist portion 102 by pulling it downward and to the rear.

[0120] Furthermore, the pelvic belt portion 30 is made of a stretchable fabric, and the stretch direction of the pelvic belt portion 30 includes a direction that slopes downward toward the center of the back, and this direction overlaps with the stretch direction of the left body portion 20B and the right body portion 20C, so it is possible to further correct the waist portion 102 by pulling it downward and rearward.

[0121] Furthermore, a downwardly recessed portion 12 is provided at the upper central portion of the front of the waist top portion 10, so that stress is applied to the front recessed portion 12 while the waist portion 102 is pulled further downward and rearward at the rear of the waist top portion 10 for correction, thereby improving the effect of correcting the waist portion 102.

[0122] Furthermore, the depth dimension X of the rear recess 11 of the waist top portion 10 is set to be larger than the depth dimension Y of the front recess 12 of the waist top portion 10, so that the waist 102 can be reliably corrected.

[0123] Furthermore, the depth Y of the front depression 12 is set to 0.1 to 1 cm, so that the effect of correcting the waist 102 can be increased.

[0124] Furthermore, the front depression 12 is formed in a V-shape, and the angle β of the opposing inclined lines 12a of the V-shape is set to 0.5° to 5° with respect to the horizontal direction, thereby further increasing the effect of correcting the waist region 102.

[0125] Furthermore, the waist top section 10 has a front waist top section 10A located in the front, a left waist top section 10B located from the left side to the rear, and a right waist top section 10C located from the right side to the rear. The front waist top section 10A is made by overlapping at least two pieces of fabric front and back so that they cross each other while slanting downward, forming a front depression 12. The upper edge 10A' of the front and rear overlapping sections is not connected to the opposing fabric, so that the unconnected front section can shift according to the body shape when worn, improving the fit. The unconnected front section also prevents excessive tightness, improving comfort.

[0126] Furthermore, the fabric of left hip top section 10B is angled downward from the left side toward the center of the back, and the fabric of right hip top section 10C is angled downward from the right side toward the center of the back, with end section 10B' of left hip top section 10B and end section 10C' of right hip top section 10C overlapping each other front to back to form rear depression 11, and the upper edge sections 10B", 10C" of the overlapping front and rear sections being disconnected from the opposing fabric, allowing the disconnected rear section to shift according to the body shape when worn, improving the fit. Also, the disconnected rear section prevents excessive tightness, improving comfort.

[0127] Furthermore, the length of the non-connected portion in the front is set to 10 to 30 cm, which can reliably improve the fit and comfort.

[0128] Furthermore, the non-connected portion in the front part is formed across the entire area in the left-right direction of the front waist top part 10A, which further improves the fit and comfort when worn.

[0129] Furthermore, the ratio of the left-right length of the unconnected portion in the front to the left-right length of the unconnected portion in the rear is set to 5 to 20, thereby further improving the fit and comfort.

[0130] Furthermore, the body portion 20 is formed by overlapping multiple layers of stretchable stretch fabric, and includes a portion in which one stretch fabric stretches in one direction sloping downward toward the center of the back portion and other stretch fabric stretch in two intersecting directions. This allows the one stretch fabric that stretches in one direction to increase its stretch force, further correcting the waist portion 102 by pulling it downward, while the other stretch fabric that stretches in two directions makes it easier to stretch according to the body shape, improving the fit. The other stretch fabric that stretches in two directions also prevents excessive constriction, improving comfort. (With a 1-way fabric that stretches in one direction, the stretch force is concentrated rather than dispersed in multiple directions, making the stretch force relatively large and requiring a relatively large force to stretch. On the other hand, with a 2-way fabric that stretches in two directions, the stretch force is dispersed in multiple directions, making the stretch force relatively small and requiring a relatively small force to stretch.)

[0131] Furthermore, the leg insertion openings 50 are connected to the leg insertion sections 60, which extend downward from the leg insertion openings 50 and are made of a stretchable fabric with a width of 2 to 10 cm, so that the force applied to the leg insertion openings 50 when correcting the waist 102 can be distributed to the leg insertion sections 60. This alleviates excessive tightness at the leg insertion openings 50 and improves comfort.

[0132] Furthermore, the first side edges 20b22, 20c22 of the second left body portion 20B2 and the second right body portion 20C2 are arranged so as to form a substantially triangle between the first side edges 20b12, 20c12 of the first left body portion 20B1 and the first right body portion 20C1 and the first bottom edges 20b14', 20c14' of the first left body portion 20B1 and the first right body portion 20C1, with the front side being cut out in a substantially triangular shape. The inclined line slopes in the opposite direction to the sides 20b12, 20c12, and the missing, approximately triangular front side is a non-overlapping area with the first left body part 20B1 and the first right body part 20C1, and this area is configured to have only the first left body part 20B1 and the first right body part 20C1.This reduces the stretching force and reduces the restriction on the movements of the user wearing the lower limb clothing 1 at the missing, approximately triangular front side.

[0133] Furthermore, the second left body portion 20B2 and the second right body portion 20C2 have curved lines 20b25, 20c25, which are curved in an arc shape so as to correspond to the lower ends of the buttocks of the human body 100 and to leave the upper sides of the rear portions of the left body portion 20B and the right body portion 20C in a substantially arc-shaped cutout. As a non-overlapping area with the right body part 20C1, this area is configured to have only the first left body part 20B1 and the first right body part 20C1, so that the stretching force can be reduced and the restriction on the movement of the buttocks of the user wearing the lower limb clothing 1 at the upper side of the missing approximately arc shape can be reduced, and the buttocks can be lifted and held by the curved lines 20b25, 20c25 (Figure 17).

[0134] Furthermore, the second side edge 20b13 of the first left body portion 20B1 and the second side edge 20c13 of the first right body portion 20C1 are connected by sewing with a rubber-like thread 20D, and a stretchable fabric 20E that can stretch in the vertical direction is provided at a position overlapping with the sewing position of the rubber-like thread 20D, so that it is possible to further correct the waist region 102 by pulling it downward.

[0135] Furthermore, in areas where the stretch fabric is a 1-way fabric that stretches in one direction, the stretch force is not dispersed in multiple directions, and the stretch force can be improved.

[0136] Furthermore, by configuring the lower limb garment 1 of the present invention as in the above embodiment, it is possible to increase the ratio R of the radius of curvature R2 of the arc-shaped approximation of the curve connecting the tip of the spinous process 100A1 of the first lumbar vertebra 100A to the tip of the spinous process 100E1 of the fifth lumbar vertebra 100E before the garment is worn on the human body 100 from 1.3 to 2.5, as shown in Figure 18. This allows the forward tilted pelvis to be comfortably straightened. [Number 1] R=R2 / R1

[0137] Here, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications and applications are possible within the scope of the claims.

[0138] For example, in the embodiment described above, the front waist top portion 10A is formed by overlapping two pieces of folded fabric 10a1″, 10a2″ front and back so that they are inclined downward in opposite directions and cross each other, thereby forming the front depression 12, but the required effect can also be achieved by overlapping two or more pieces of folded fabric. In other words, the front waist top portion 10A can also be formed by overlapping at least two pieces of folded fabric 10a1″, 10a2″ front and back so that they are inclined downward in opposite directions and cross each other, thereby forming the front depression 12, thereby forming the required effect.

[0139] [Comparative Example] Comparative examples of the present invention are shown in Figures 19 and 20. That is, the comparative examples of the present invention show a comparison between the lower leg garment 1 of the present invention shown in Figures 19(a) and 20(a) and an example of conventional lower leg garment 1 shown in Figures 19(a) and 20(a).

[0140] In other words, the lower leg clothing 1 of the present invention shown in Figures 19(a) and 20(a) is 5 cm higher in height (the height position of the upper edge 10A' of the lower end 12c of the front depression 12 of the waist top 10) than the conventional lower leg clothing 1 shown in Figures 19(a) and 20(a), and the upper edge 11d of the lower end 11c of the rear depression 11 is 3 cm lower.

[0141] As a result, the upper edge 10A' of the front part of the waist top portion 10 is positioned above the third lumbar vertebra of the human body 100 when worn on the human body 100, and the upper edge 11d of the lower end portion 11c of the rear recess portion 11 is positioned below the fifth lumbar vertebra of the human body 100 when worn on the human body 100, thereby improving the corrective effect compared to conventional lower limb clothing 1 (there was a demand for further improving the corrective effect of conventional lower limb clothing 1).

[0142] However, as a result of improving the corrective effect in this way, the feeling of tightness on the human body 100 increases, which affects the fit and comfort of wearing.

[0143] For this reason, in the lower limb garment 1 of the present invention, the upper edge portions 10A', 10B', 10C' of the front and rear overlapping portions are not connected to the opposing fabric in the rear depression 11 and the front depression 12. This allows the unconnected portions to shift according to the body shape when worn, improving the fit and comfort.

[0144] Furthermore, the lower limb garment 1 of the present invention uses a 2-way fabric that stretches in two intersecting directions in the body portion 20 and the crotch portion 40. This allows the garment to stretch easily according to the body shape, further improving the fit and comfort.

[0145] Furthermore, the lower leg garment 1 of the present invention is provided with leg insertion sections 60 having a width of 2 to 10 cm, and the leg insertion sections 60 are made of a stretchable fabric, thereby alleviating excessive tightness at the leg insertion openings 50 and improving comfort (it has been pointed out that conventional lower leg garments 1 have a high tightness at the leg insertion openings 50 due to the corrective effect).

[0146] When the lower limb garment 1 of the present invention was worn by a user, the force (spring constant) generated when stretched by a unit length was measured at the lower end 12c of the front depression 12 at the front of the waist top 10 (position a in Figure 19(a)), at a front position that is the same position in the vertical direction as the lower end 11c of the rear depression 11 (position b in Figure 19(a)), and at the lower end 11c of the rear depression 11 at the waist top 10 (position b' in Figure 20(a)), as shown in Figure 21.

[0147] As a result, the force (spring constant k a ) generated when the lower end 12 c of the front depression 12 at the front of the waist top 10 (position a in FIG. 19( a)) is stretched by a unit length is 0.233 N / mm, the force (spring constant k b ) generated when the front position (position b in FIG. 19( a)) which is the same position in the vertical direction as the lower end 11 c of the rear depression 11 is stretched by a unit length is 0.197 N / mm, The force (spring constant kb') generated when the lower end 11c of the rear depression 11 (position b' in Figure 20(a)) is stretched by a unit length is 0.273 N / mm. In addition, the force ka' generated when the lower end 11c of the rear depression 11 is stretched by a unit length at a rear position (position a' in Figure 20(a)) that is the same position in the vertical direction as the lower end 12c of the front depression 12 in the front of the waist top part 10 is stretched by a unit length is of course 0 because no fabric is provided at that same position.

[0148] That is, the force ka generated when the lower end 12c of the front depression 12 at the front of the waist top 10 (position a in FIG. 19(a)) is stretched by a unit length is larger than the force kb generated when the lower end 12c is stretched by a unit length at a front position (position b in FIG. 19(a)) that is the same position as the lower end 11c of the rear depression 11 in the up-down direction, and the force kb' generated when the lower end 11c of the rear depression 11 is stretched by a unit length at a front position (position b in FIG. 19(a)) that is the same position as the lower end 11c of the rear depression 11 in the up-down direction is larger than the force kb generated when the lower end 11c of the rear depression 11 is stretched by a unit length. The force kb' generated when stretched by a unit length at (position b' in Figure 20(a)) is greater than the force ka generated when stretched by a unit length at the lower end 12c of the front depression 12 at the front of the waist top 10 (position a in Figure 19(a)).Furthermore, the force ka generated when stretched by a unit length at the lower end 12c of the front depression 12 at the front of the waist top 10 (position a in Figure 19(a)) is greater than the force ka' generated when stretched by a unit length at the rear position (position a' in Figure 20(a)) which is the same position in the vertical direction as the lower end 12c of the front depression 12.This makes it possible to straighten the forward-tilted pelvis, maintain correct posture, and eliminate arching of the lower back.

[0149] Here, ka and kb can be obtained by subtracting a predetermined length M1 from a force B1 generated at positions a and b when the lower leg garment 1 of the present invention is pulled forward by a predetermined length M1 at positions a and b while worn by a user. Also, kb' can be obtained by subtracting a predetermined length M2 from a force B2 generated at position b' when the lower leg garment 1 of the present invention is pulled backward by a predetermined length M2 at position b' while worn by a user. [Number 2] ka,kb=B1 / M1 kb'=B2 / M2 [Explanation of symbols]
