Description

[Technical field]

[0001] The present invention relates to a lower body garment for preventing lower back pain. [Background technology]

[0002] Some conventional lower body garments have a structure that fits into a waist cavity as shown in Fig. 13. Also, as shown in Fig. 14, there are garments that use a fabric area smaller than the original dimensions of the human body in addition to the structure of Fig. 13.

[0003] In addition to the above-mentioned configuration, the leg openings may be narrowed. Furthermore, there are also some that use elastic strings around the leg openings.

[0004] Known lower body clothing (Patent Document 1) includes lower body clothing such as pants and girdles that lift and correct the hips without squashing the roundness of the buttocks, creating a well-defined hip line.

[0005] As shown in FIG. 2, the inner side of the back side main body 14 is provided with a patch 20 formed by connecting a pair of triangular left and right cloths 21, 22 with hanging edges 21b, 22b along the gluteal cleft, and the patch 20 and the main body 14 are sewn together at upper edges 21a, 22a on the waist side of the left and right cloths 21, 22 and the hanging edges 21b, 22b along the gluteal cleft, while the inclined edges 21c, 22c connecting the tips of the upper edges 21a, 22a and the hanging edges 21b, 22b are not sewn together with the main body 14 and are left floating. The inclined edges 21c, 22c of the patch 20 are sized so that they do not reach the apexes T, T of the left and right buttocks, and the patch 20 is made of a stretchable material, so that the portions along the hanging edges 21b, 22b are made into tightening force portions 23 and the portions on the inclined edges 21c, 22c side are made into weak tightening force portions 24.

[0006] In the known lower body garment (Patent Document 2), there is provided women's underwear with a thick hem that does not show through outerwear, is comfortable to wear, and is easy to manufacture.

[0007] As shown in Figure 1, women's underwear is made by sewing together pieces of fabric that make up the body, and the part that corresponds to the end of the body, which must be curved in the conventional pattern, is made into a double structure by creating a pattern that can directly change it, and the part other than the corresponding part is sewn to the end of the body.

[0008] Among known lower body garments (Patent Document 3), there is one that provides women's shorts with improved athletic functionality and comfort.

[0009] As shown in Figure 1, the front body corresponding to the lower abdomen is made of a fabric stretchable in the horizontal direction, and the back body corresponding to the buttocks is made of a fabric stretchable in the vertical direction. When the lower abdomen moves significantly due to twisting the torso or breathing, the front body stretches in the horizontal direction, relieving the unreasonable constraint on the human body movement of the lower abdomen, and when the buttocks move significantly due to sitting or bending forward, the back body stretches in the vertical direction, relieving the unreasonable constraint on the human body movement of the buttocks, thereby reducing fatigue and improving athletic functionality while eliminating excessive slack.

[0012] [Patent Document 3] Japanese Patent Application Publication No. 7-207502 Summary of the Invention [Problem to be solved by the invention]

[0013] In the conventional lower body clothing, as in the above-mentioned Patent Documents 1 to 3, lower body clothing that lifts the hips, is comfortable to wear, and has athletic functionality and comfort has been invented and devised.

[0014] In conventional lower body clothing, as described in the above-mentioned Patent Documents 1 to 3, lower body clothing such as pants and girdles have been invented and devised that can lift and shape the hips without flattening the roundness of the buttocks and create a well-defined hip line.

[0015] However, conventional lower body clothing has the problem of inducing a forward leaning posture, which can lead to back pain and other ailments.

[0016] These factors have the potential to affect the human skeleton, muscles, and blood circulation.

[0017] Furthermore, among conventional lower body clothing, there are pants and shorts that have leg openings, but these have inconveniences for the human body. For example, when walking or other activities that constantly move the legs and activate the pelvis and gluteal muscles (gluteus maximus, gluteus medius, gluteus minimus, etc.), the fabric on the front and back of conventional lower body clothing is often pulled toward the crotch area.

[0018] As the fabric on the front and back is pulled toward the crotch area, the waistline is also pulled downward. As a result, pressure and strain are placed on the pelvis, including the sacrum and ilium.

[0019] The weight of the fabric on the front and back presses on the ilium, which is the pelvis, due to the left and right movements of the human body. This weight, along with pressure and strain, has the disadvantage of passing through the ilium and going down from the back to the abdomen.

[0020] The lower back is essentially the center of the human body and is the area most affected by the upper and lower body.

[0021] However, some conventional lower body garments are constructed in such a way that they place a burden or pressure on the waist, which has an adverse effect on the bones and muscles of the upper and lower body.

[0022] Some conventional lower body clothing uses elastic strings around the entire waistline. The elastic strings put a strain on both sides of the pelvis that are tilted up and down due to the movement of the human body and the tilt of the posture. The strain is thought to be greater on the side that is raised higher.

[0023] Furthermore, the leg openings of conventional lower body garments are often narrow or have elastic strings, which can cause problems with blood flow to the thighs.

[0024] In view of the above problems, the present invention provides a lower body garment having a structure that aims to minimize the effects on the human body. [Means for solving the problem]

[0025] In order to solve the above problems, one embodiment of a lower-body garment according to the present invention is a lower-body garment that is symmetrical when viewed from the front, with the left and right armpits each having a shape that spreads downward and outward, the area of ​​the buttocks fabric is larger than the area of ​​the lower abdomen fabric, the leg turn-out angle of the front portion relative to the armpits is greater than 90 degrees, the leg turn-out of the back portion continues from the lower end of the armpits towards the back, and the leg turn-out angle of the back portion relative to the armpits is greater than the leg turn-out angle of the front portion.

[0026] In one embodiment of the present invention, the lower abdomen fabric and the buttocks fabric are configured such that the lower abdomen fabric waist at the upper end and the center of the buttocks fabric waist are sagging downward.

[0027] In one embodiment of the present invention, the upper waistline side portions and the lower leg openings of the left and right side portions are made of only a stretchable knit fabric.

[0028] In one embodiment of the present invention, the lower-body garment is composed of left pants and right pants which are symmetrical and have a left lower abdomen line and left buttocks line, and a right lower abdomen line and right buttocks line which flare out downward and outward from the ends of the straight left and right waistlines.

[0029] In one embodiment of the present invention, the length of the left and right buttock lines is longer than the length of the left and right lower abdominal lines, and the inclination angle β of the buttock lines relative to the left and right waistlines is greater than the inclination angle α of the lower abdominal line relative to the left and right waistlines.

[0030] In one embodiment of the present invention, the lower end of the lower abdomen fabric has a trapezoidal crotch portion that spreads downward from the center and is sewn to the center of the lower end of the buttocks fabric, and both sides of the crotch portion and the leg openings are continuous.

[0031] One embodiment of the present invention is configured to include elastic strings of different lengths extending from the center of the lower abdomen fabric, the lower abdomen fabric waist above the buttocks fabric waist, and along the left and right waistlines of the buttocks fabric.

[0032] In one embodiment of the present invention, the length range of the elastic cord is such that the length of the buttocks waist is longer than the length of the lower abdomen waist. Effect of the Invention

[0033] The V-shaped waistline and fabric weight shifting configuration of the present invention reduces pressure on the lower back from above and from the sides. This allows the natural movement of the ilium, which is the pelvis, to be unimpeded. The positive effect of the "V-shaped" waistline on the human body is that it reduces the pressure on the lumbar spine and pelvis even when sitting or bending forward.

[Figure 14] It is a conventional garment for the lower body (shorts with a fabric area smaller than the actual size of the human body). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] 3 and 4 are front and back views of a lower-body garment according to an embodiment of the present invention. As shown in each figure, the waistline of the present invention is configured in a "V shape" (hereinafter referred to as "V shape").

[0036] The invention of the "lower body garment for preventing lower back pain" is a "configuration derived from verification of the daily movements of the human body," so the present embodiment based on the verification will be described below.

[0037] 《Point of focus》 This invention focuses on the causes of forward-leaning posture and back pain, and devise lower body clothing to alleviate discomfort that occurs in the "lower back." It is based on the shape of the waistline and the shifting of fabric weight.

[0038] When making clothing for the lower body, we believe that the most important thing to consider is its impact on the "waist," which is the center of the human body. The relationship between the waistline of a lower body garment and the "hips" is always close and is considered to be unavoidable.

[0039] For these reasons, the objective of lower body clothing for preventing lower back pain is to provide a configuration that can accommodate the movement of the "lower back" and reduce the burden on the "lower back."

[0040] In other words, in one embodiment of the present invention, it is necessary to select a fabric that reduces strain on the lower back regardless of the posture during daily work or movements, and it is considered appropriate to use a stretchy knitted fabric that can accommodate any posture.

[0041] Furthermore, from an examination of the "relationship between the movement of the human body and the pelvis" described below, it is believed that the structure of conventional lower body clothing affects not only the lower body but also the upper body.

[0042] Therefore, based on the conventional configuration of lower body clothing, the present invention has come up with a configuration that can avoid the influence on the waist and reduce pressure and burden on the bones and muscles.Furthermore, a configuration with a generous fabric area for lower body clothing that does not put a burden on the human body is devised.

[0043] "verification" (1) Let's examine the relationship between muscle fibers and waistline shape in the human body. The lower back is the center of the human body and is considered to be the area most affected by the upper and lower body.

[0044] The muscles of the human body are made up of a structure of muscle fibers. Most of them are vertical (longitudinal) muscle fibers. When the human body moves, the movement is considered to be active.

[0045] Taking into consideration this structure of the human body, it was necessary to devise a shape for the waist area, which is the center of the human body, that would follow the structure of the human body rather than a horizontal (lateral) waistline.

[0046] This is because a horizontal waistline has the disadvantage that its lateral movement blocks the vertical movement of muscle fibers, putting a strain on muscle function.

[0047] Therefore, this embodiment adopts a "V-shaped" waistline that follows the vertical muscle fibers, which is expected to reduce vertical resistance. See Figure 11.

[0048] The "V-shaped waistline" of this embodiment reduces pressure and strain on the latissimus dorsi muscle, and is expected to maintain good blood flow to both the upper and lower body.

[0049] (2) Verify the movement of the pelvis due to human body movements. As shown in the human body image diagram in Figure 10, the direction indicated by the arrow is the natural movement structure of the pelvis.

[0050] For example, when the human body moves from a standing to a sitting position, the sacrum normally begins to gradually arch downward and forward. See Figure 10, a human body image. In tandem with the movement of the sacrum, the ilium also arches and moves downward, just like the sacrum.

[0051] The movement of the ilium is linked to the movement of the inverted triangle shape of the sacrum, so it moves from the outside to the inside and downwards, toward the tailbone. See Figure 10 "Back side."

[0052] In addition, the ilium not only moves up and down, but also moves side to side (rounding) at the same time. See Figure 11.

[0053] Furthermore, when sitting with the knees together and the thighs facing inward towards the body, the lower part of the pelvis spreads out to the left and right (in a ㇵ shape). It can be seen that the area of ​​the buttocks and thighs in this position is larger than that in the upright position (see Figure 11).

[0054] In addition, it is believed that the structure of the pelvis is such that it will fall forward when pressure or compression is applied from behind, and as a result, the sacrum and coccyx are structured to rise upward. Considering these points, if you imagine moving your pelvis in the opposite direction to the arrow, it may be difficult to take a large step forward from your thigh. See Figure 10 (image of the human body). This is thought to be the reason why people walk with short strides rather than long ones.

[0055] For these reasons, the present invention is designed with an emphasis on the area of ​​fabric that does not obstruct the movement of the gluteal muscles (gluteus maximus, gluteus medius, gluteus minimus, etc.) that are linked to the movement of the pelvis, which has a large and wide range of motion. See Figure 11 "Sitting Posture". In this embodiment, the configuration takes into consideration the extra fabric area in the front and back.

[0056] The present invention has been designed with the area of ​​the buttocks fabric in mind, taking into account such up-down and left-right movements of the ilium and buttocks.

[0057] This defined area does not put strain on the bones or muscles that make up the human body structure, and combined with the "V-shaped" waistline, is expected to restore and maintain joint cavities (the spaces between bones). Furthermore, this configuration is expected to help prevent lower back pain.

[0058] Furthermore, the pressure from the rear of the back caused by the small area of ​​fabric around the buttocks and horizontal waistline, which are typical of conventional lower body garments, can be reduced. See FIG. 11. Therefore, this configuration can also be expected to prevent forward leaning posture.

[0059] (3) Examine the shape of the legs. The range of motion of the femur is linked to the movement of the pelvis. The range of motion of the femur, which is linked to the pelvis as described above, and the thigh, must be considered as a wide range of motion that extends widely from side to side and also up and down. See Figure 11.

[0060] For this reason, we believe that a larger, wider leg opening shape that allows for a wider range and easier leg spreading, rather than a narrower one, will reduce pressure and strain.

[0061] Taking these factors into consideration, in this embodiment, the pants have a "wide-shaped" configuration in which the leg openings are formed by sewing the left and right pants together and the crotch area.

[0062] This allows the hip joint to be moved freely without narrowing the hip joint, without restricting the range of motion of the femur and thigh, and allows the joint cavity to be maintained. For example, when wearing conventional lower body clothing and trying to spread one's legs wide, one's thighs tend to be pulled inward. In contrast, this embodiment has a "widening shape" that allows the thighs to be directed significantly outward.

[0063] Furthermore, if any material that tightens around the legs, not just elastic laces, is used for the leg openings, the strength of the material will cause the lower abdominal and buttock fabrics to be pulled downward. When the fabric of the front and back of lower body clothing is pulled toward the leg openings and crotch area, the waistline also drops downward, causing the waistline to shift downward.

[0064] If the waistline position is shifted significantly downward when worn, it may put pressure on the ilium from above, causing the pelvis to become misaligned. It is believed that compressing the leg movements from all sides affects the thigh muscles and causes some disruption in blood flow.

[0065] Taking these factors into consideration, this embodiment is designed to open up the leg openings and "not to constrict the area around the legs, not just with elastic laces," which is expected to help prevent varicose veins. Figure 11 shows an image of how it will look when worn.

[0066] Furthermore, a configuration that does not put strain on the buttocks and thighs can be achieved as shown in Figure 12.

[0067] (4) Examine the properties of elastic string and its effects on the human body. A characteristic of elastic string is that it shrinks (returns) to the center of the cut area.

[0068] Furthermore, if you connect both ends of this cut elastic string, it will form a circle (loop). The properties of the elastic string change so that it shrinks (from the outside to the inside) toward the center of the circle (ring).

[0069] Careful consideration needs to be given to the impact on the human body of using an elastic string with such characteristics around the entire waistline.

[0070] This is because the effect of an elastic string with these properties on the human body is transformed into a contraction towards the center of the body.

[0071] For example, the stronger the elasticity, the greater the burden on the lower back, even when in an upright position. Furthermore, when combined with the small surface area of ​​the conventional lower body garments described above, this burden is even greater and is placed on the waist.

[0072] This is because, as mentioned above, when it comes to the movement of the human body structure, the movement of the pelvis is a rounded movement that drops downward.

[0073] Even when in an upright position, the natural state of the human body is for the lower back to curve downwards, rather than to arch backwards.

[0074] However, the elasticated string that is in a circular (loop) shape and is used around the entire waistline puts pressure on the natural position of the human body, placing a great strain on the central area of ​​the waist.

[0075] In consideration of these points, in this embodiment, the waistline side portion 30 that directly touches the ilium is configured not to include a string or the like, including but not limited to an elastic string. Also, the position of the elasticated string at the waistline is shown at F and B. See Figures 3 and 4 (vertical striped area).

[0076] The present invention, in combination with the "V-shape" waistline, is expected to help prevent herniated discs by not using elastic strings at the waistline 30.

[0077] Furthermore, this configuration can also reduce the influence of the tilted pelvis on both sides, which is caused by movement or posture tilt, on the ilium and femur.

[0078] (5) Examine the structure and weight of the fabric that presses on the waist, which is the center of the human body. For example, consider how the horizontal waistline of conventional lower body clothing affects the human body when the pelvis moves downward toward the back.

[0079] With a horizontal waistline, the abdominal ilium blocks the upward movement toward the armpits, suppressing it from above.

[0080] Therefore, it can be said that a horizontal waistline, caused by the tilt of the pelvis due to movement and posture, places a large load on the ilium.

[0081] In addition, in conjunction with the horizontal waistline, the weight of the lower body fabric at the front and back places a heavy pressure on the loaded ilium.

[0082] In this embodiment, the area of ​​the buttocks fabric is larger than the area of ​​the lower abdomen fabric. The reason for this is that by sewing the buttocks crotch widths 31L, 31R to the lower abdomen crotch widths 3L, 3R and pulling them, the weight of the buttocks fabric is pulled (moved) forward from the lower buttocks side. See Figure 5.

[0083] The present invention reduces the burden on the lower back by shifting the weight of fabric between the front and back of the lower body garment and by using a "V-shape" in combination, so that the garment can accommodate the movements of the human body. Therefore, the uncomfortable feeling of pressure or strain on the lumbar spine is reduced.

[0084] The configuration of the lower body garment in this embodiment will be described below. In this embodiment, a stretchable knitted fabric is used. (From here on, "left and right" will be omitted and the symbols will be used.)

[0085] <overview> The outer shape of the "lower body garment for preventing lower back pain" of the present invention, as shown in front view 3 and back view 4, is a shape that flares out downwards. The leg angle 1θ of the front part and the leg angle 2θ of the back part are determined by the lower abdomen line inclination angle α, the buttocks line inclination angle β, and the width of the crotch area. (The width of the crotch will be described later.) Therefore, no measurements are required when making left and right pants. In this embodiment, the normal angles are 1θ=100 degrees and 2θ=135 degrees.

[0086] 1 and 2 are plan views of a symmetrical pair of left pants L (FIG. 1) and right pants R (FIG. 2) of lower-body garments according to the present invention. The shapes of the left and right pants will be described below with reference to these drawings.

[0087] <Waistline> The left and right pants L and R each have straight left and right waistlines 1L and 1R at the top. In this embodiment, in order to create a "V-shape," the sizes of waistlines 1L and 1R are set based on a human hip size that is larger than the actual waist concavity. By using the hip size as a guide, you can avoid tightness around the waist when wearing the garment. Also, by using the top size of the buttocks as a base, you can put it on and take it off without any inconvenience.

[0088] Moreover, it is preferable that the vertical width of the waistlines 1L and 1R be set to a dimension that matches the vertical width of elastic strings or the like that will be attached later.

[0089] <Wing> The side regions 5L, 5R are lines that descend vertically from the centers of the waistlines 1L, 1R. In this embodiment, it is preferable that the length of the side portions 5L, 5R is the same as the vertical width of the pelvis (the length to the base of the femur) (taking into consideration the range of motion of the femur).

[0090] <Lower abdomen side, buttocks side, inclination angle> Setting the inclination angles α and β shown in Figures 1 and 2 to follow the curves of the abdomen and buttocks helps to reduce pressure on the human body caused by changes in pelvic movement.

[0091] The lower abdominal lines 2L, 2R and the buttock lines 4L, 4R are lines that extend downward and outward at an inclination angle relative to the straight waistlines 1L, 1R.

[0092] The inclination angles of the waistlines 1L and 1R extending downward and outward from both ends thereof are set as a lower abdominal line inclination angle α and a buttocks line inclination angle β.

[0093] In this embodiment, it is preferable to set the lower abdomen line inclination angle α to about 100 degrees, and the buttocks line inclination angle β to about 110 degrees. The lower abdomen line inclination angle α is preferably smaller than the buttocks line inclination angle β. However, this does not apply to certain body types (e.g. pregnant women).

[0094] <Buttocks line> The hip lines 4L, 4R are inclined at a hip line inclination angle β with respect to the waist lines 1L, 1R, and the length from the lower end of the hip waist lines 11L, 11R to the crotch position is set. In this embodiment, the length of the buttocks lines 4L, 4R is preferably long enough to largely surround the buttocks and cover the crotch area (taking into consideration the up-down and left-right movements of the buttocks).

[0095] <Lower Abdominal Line> The lower abdomen lines 2L, 2R are inclined at an angle α with respect to the waist lines 1L, 1R, and the length from the lower end of the lower abdomen waist lines 12L, 12R to the crotch position is set. In this embodiment, the length of the lower abdomen lines 2L, 2R is preferably the length up to the crotch area. (This takes into account the up / down and left / right movements of the lower abdomen.)

[0096] The length of the buttock lines 4L, 4R is set to be longer than the length of the lower abdominal lines 2L, 2R.

[0097] The reason for this is that, as shown in the human body image diagram of FIG. 10, the natural swelling of the buttocks (hips) of the human body is usually larger than the swelling of the abdomen. This angle allows you to create an arch that follows the curve of your lower abdomen and buttocks. However, this does not apply to certain body types (e.g. pregnant women).

[0098] <crotch> The shapes of the trapezoidal crotch regions LL and RR extending below the lower abdominal lines 2L and 2R shown in Figs. 1 and 2, and the crotch regions LL1 and RR1 included below the buttock lines 4L and 4R will be described. The shape of the crotch portion is included in the left and right pants L and R, and the shapes of these are positioned at the bottom of the drawing.

[0099] In this embodiment, the widths of the lower abdominal crotch regions LL, RR and the buttock crotch regions LL1, RR1 are based on the lengths of the crotch widths 31L, 31R at the lower ends of the buttock lines 4L, 4R. The length of the crotch width is preferably determined based on the width between the hip joints.

[0100] In this embodiment, the vertical widths of the lower abdominal crotch regions LL, RR and the buttock crotch regions LL1, RR1 shown in Figs. 1 and 2 are based on the length of the buttock crotch vertical widths (midline) LX1, RX1.

[0101] In addition, the vertical widths LX1, RX1 of the crotch portion of the buttocks need to be preset with the leg openings (back portion) 61L, 61R, which will be described later. Therefore, if the following steps are performed in advance, the vertical widths LX1, RX1 of the crotch portion of the buttocks can be easily set.

[0102] The length of the leg openings (back part) 61L, 61R is determined by connecting the crotch widths 31L, 31R at the lower ends of the buttock lines 4L, 4R to the leg openings (thigh part) 62L, 62R. (The leg openings will be described later.)

[0103] At this point, the hip lines 4L, 4R are provided with hip crotch widths 31L, 31R and hip crotch length widths LX1, RX1.

[0104] Here, a process is added to make the buttock crotch regions LL1, RR1 and the lower abdomen crotch regions LL, RR overlapping with each other to have the same shape.

[0105] To provide the crotch areas LL and RR at the lower ends of the lower abdominal lines 2L and 2R, 1. Align the line that will become the midline of the crotch area. Place the crotch width 31L, 31R on the lower end of the lower abdomen line 2L, 2R, and Align the lines so that they connect 4L, 4R, and the lower abdominal lines 2L and 2R. (Lines LX and RX are the center lines of the trapezoid shown in Figure 9) 2. Set the groin midline LX and RX. The same length as the vertical widths LX1 and RX1 of the crotch of the buttocks prepared in the previous step is set as the vertical widths LX and RX of the crotch of the lower abdomen below the lower abdomen lines 2L and 2R. 3. Set the crotch width to 3L and 3R. The crotch widths 3L and 3R of the lower abdomen are set to the same length as the crotch widths 31L and 31R of the buttocks that are placed against the lower ends of the lower abdomen lines 2L and 2R.

[0106] By the work up to this point, two sides of the trapezoid are provided: the left crotch portion LL, the left crotch portion LL1, and the right crotch portion RR, the right crotch portion RR1. Therefore, at this stage, the lengths of the lower abdominal groin sutures LP, RP and the lower abdominal groin leg openings LZ, RZ are determined. At the same time, the lengths of the buttocks crotch sutures LP1, RP1 and the buttocks crotch leg openings LZ1, RZ1 are determined.

[0107] By the above steps, the four sides of the trapezoid, i.e., the left crotch portion LL, the left crotch portion LL1, the right crotch portion RR, and the right crotch portion RR1, are completed and the left and right pants L, R are provided.

[0108] The crotch width 3L, 3R on the lower abdomen side determined by these steps is connected to the lower ends of the armpits 5L, 5R to set the leg opening front parts 6L, 6R. At the same time, 1θ is also provided. (The leg movement will be discussed later.)

[0109] <Leg Movement> In this embodiment, the inclination angle in the drawing is determined by the lower end positions of the armpits 5L, 5R and the lengths of the crotch widths 31L, 31R, so there is no need to measure the leg opening angles 1, 2θ relative to the armpits.

[0110] Using the lower ends of the above-mentioned waist regions 5L and 5R as a reference, the leg openings are set on the lower abdomen fabric side and the buttocks fabric side. It is preferable to determine the length of the fabric on the lower abdomen side taking into consideration the range of motion of the femur and hip joint. Additionally, it is preferable to adjust the length of the buttocks fabric, taking into consideration the range of motion of the thighs and buttocks.

[0111] In this embodiment, the length of the leg openings (thighs) 62L, 62R is preferably determined in consideration of the range of motion of the thighs.

[0112] The length of the leg openings (back portion) 61L, 61R is determined by connecting the leg openings (thigh portion) 62L, 62R to the crotch widths 31L, 31R. In addition, the leg openings (front portion) 6L, 6R are determined by connecting the leg openings (thigh portion) 62L, 62R to the crotch widths 3L, 3R.

[0113] In this embodiment, the length of the leg openings (thighs) 62L, 62R is not necessarily limited. This length is set in consideration of the range of motion of the thighs, but the size of the fabric area covering the buttocks can also be adjusted. See FIG. 12.

[0114] <Manufacturing method> In this embodiment, the left pants L and right pants R shown in Figs. 1 and 2 are sewn together, and the crotch regions LL and RR of the lower abdomen and the crotch regions LL1 and RR1 of the buttocks are sewn together to give a regular outer shape.

[0115] The crotch suture is a double structure in which the crotch parts LL and RR of the lower abdomen are placed on the inside and the crotch parts LL1 and RR1 of the buttocks are placed on the outside.

[0116] Elastic strings or the like to be attached to the waistline can also be sewn to the lower abdominal waist F and buttocks waist B in the ranges shown in Figures 3 and 4.

[0117] It is also possible to thread an elastic string through the bag stitching. Widen the vertical width of the left and right waistlines 1L and 1R shown in Figures 1 and 2, and sew a bag stitch around the entire circumference of the waistlines. It is also possible to pass a string through the lower abdomen waist F above the lower abdomen fabric waist 8 and the buttocks waist B above the buttocks fabric waist 9 shown in Figures 3 and 4, which have been sewn with a hollow stitch, and tie the string at both ends of the lower abdomen waist F and the buttocks waist B. In this case, two holes are required on both ends to tie the cut string.

[0118] About elastic strings Elastic strings include rubber strings, flat rubber strings, woven rubber strings, mesh rubber strings, stretch lace strings, etc. (The strength of all strings is not uniform.) In this embodiment, normal strength (medium) is preferred. Moreover, the range of the lower abdominal waist F and the buttocks waist B is preferably determined by the width of the ilium on the abdominal side and the back side as shown in FIG. However, the most optimal range is to take into account the range of motion of the ilium. The elasticated lower abdominal waist F is shorter than the buttocks waist B.

[0119] The manufacturing method of this embodiment will be described below.

[0120] The left pants L and the right pants R shown in Figures 1 and 2 are sewn together. This forms the midline of the lower body garment of this embodiment. <Lower abdominal side, buttocks side suture>

[0121] The right buttock waistline 11R and right buttock line 4R of the right pair of pants R shown in FIG. 2 are sewn together with the left buttock waistline 11L and left buttock line 4L of the left pair of pants L shown in FIG.

[0122] The right lower abdominal line 12R and the right lower abdominal line 2R of the right pants R shown in FIG. 2 are sewn together with the left lower abdominal line 12L of the left pants L shown in FIG. 1 and the left lower abdominal line 2L of FIG.

[0123] After the previous sewing process, the result will be the three-dimensional diagram shown in Figures 5 and 9. This configuration forms a "V-shape" in which the central portions of lower abdominal fabric waist 8 and buttock fabric waist 9 shown in Figures 3 and 4 slope downward, which acts to reduce strain on the lower back.

[0124] Next, the left crotch vertical width LX on the lower abdominal side of the crotch midline shown in FIG. 8 and the right crotch vertical width RX on the lower abdominal side are sutured. See Fig. 5 and Fig. 9 are sewn together to form the configuration of Fig. 8.

[0125] <Groin stitching> The structure shown in Figure 5 allows for the aforementioned weight transfer of fabric by the stitching in the crotch area, as shown in Figure 6, and also stabilizes the "V-shaped" waistline.

[0126] The trapezoidal crotch portions shown in Figures 1 and 2 are overlapped, with the left crotch portion LL on the lower abdomen side and the right crotch portion RR on the lower abdomen side on the inside, and the left crotch portion LL1 on the buttocks side and the right crotch portion RR1 on the buttocks side on the outside. (This results in the formation shown in Figure 6.)

[0127] The left crotch width 31L on the buttocks side and the right crotch width 31R on the buttocks side shown in Figure 9 are overlapped outward, and the left crotch width 3L on the lower abdomen side and the right crotch width 3R on the lower abdomen side are pulled inward and sutured. The stitching of the crotch portions 31L, 31R and 3L, 3R acts to pull the weight of the buttocks fabric 20 downward and forward. See Figs. 9 and 3.

[0128] Successively, stitch each double overlapping edge. Suturing the left groin LZ on the lower abdomen on the leg side and the left groin LZ1 on the buttocks. Suturing the right groin RZ on the lower abdomen on the groin side and the right groin RZ1 on the buttocks. Suturing the left crotch suture LP on the lower abdomen on the buttocks side and the left crotch suture LP1 on the buttocks. Suturing the right crotch suture RP on the lower abdomen on the buttocks side and the right crotch suture RP1 on the buttocks. The above stitches complete the double-layered crotch section. See Figures 6 and 8.

[0129] By the above steps, the outer shape of the lower body garment of this embodiment shown in Figs. 3 and 4 is completed, and at the same time, the left and right leg openings are completed. The configuration shown in Figures 3 and 4 in which the lower ends of the lower abdomen fabric 10 and the buttocks fabric 20 are overlapped at the center and the crotch area is sewn together causes the buttocks fabric 20 to pull the lower abdomen fabric 10, allowing the weight of the fabrics to be transferred.

[0130] The sewn lower abdominal fabric 10 shown in FIG. 3 has a lower abdominal fabric waist 8 at its upper end, the range of which is within the range between the left side 5L and the right side 5R. The buttocks fabric 20 shown in FIG. 4 has a waist 9 at its upper end, and its range lies within the range of the left side 5L and the right side 5R.

[0131] In this embodiment, the completed left leg openings 6L, 62L, 61L and right leg openings 6R, 62R, 61R shown in FIG. 6 have an expandable shape and are made only of stretchable knitted fabric. Additionally, the waistline side portions 30 shown in Figs. 3 and 4 are also made only of stretchable knit fabric. This also reduces the strain on the armpits mentioned above.

[0132] In addition, the design does not use elastic laces, etc., which helps to reduce the risk of the waistline shifting significantly downward due to the shape of the leg openings or laces, etc., and is also expected to reduce the strain placed on the lower back from above.

[0133] Attaching elastic strings, etc. After the left and right pants are sewn together, elastic strings are attached to the lower abdomen waist F and the buttocks waist B as shown in Figures 3 and 4. It is also possible to sew the waistline into a bag shape and pass the strings through it, and it is also possible to sew them to the lower abdomen waist F and buttocks waist B positions.

[0134] In this embodiment, the length of the attached string is taken into consideration depending on the strength of the elastic string, and it is preferable that the elastic strength is medium.

[0135] This configuration, by determining the attachment position and range, has the effect of not placing stress on the waistline side portion 30 shown in Figures 3 and 4, making it possible to adjust the waist size only at the lower abdominal waist F and buttocks waist B, and making it easier to put on and take off. In addition, as shown in FIG. 6, although the waistlines 1L and 1R are larger than the depression in the lower back, the garment can be prevented from slipping down when worn.

[0136] <Examples of the present invention> It is most suitable for clothing such as underwear that comes into direct contact with the human body.

[0137] Since the present invention is designed with consideration given to maintaining good blood flow, it is preferable to use it as clothing for relaxing while spending unconscious time. Mainly pajamas and sweat suits.

[0138] The clog pants produced in accordance with the other embodiment are worn and the legs are opened in the same manner as described above. Unlike conventional lower body clothing, which is made with trousers and the like, the fabric does not bunch up when the legs are spread apart, and there is no feeling of pressure on the groin or hip joints.

[0139] In addition, I was able to spread my legs wide without feeling any sense of correction from the fabric that would turn my knees inward even though I was trying to spread my legs outward.

[0140] Taking this into consideration, when making a long skirt or the like, it is preferable to take the movement of the thighs into consideration and to use slits on the left and right sides.

[0141] The inventor continuously wore the garment made according to the present invention and the results are reported below.

[0142] Example 1 By wearing the present invention continuously for a long period of time, the narrowing of the hip joints can be reduced.

[0143] Example 2 By wearing the present invention continuously for a long period of time, the waistline is positioned higher than before the present invention was worn (closer to the solar plexus).

[0144] In addition, the obi belt for the traditional Japanese dress "Kimono (Japanese clothing)" is tied at the torso area covering the solar plexus. (How to wear a kimono for women)

[0145] When we examine these two points, we find that the natural position of the waist of the torso of the human body is around the solar plexus area.

[0146] Furthermore, we will observe the curve of the baby's torso while he is unconscious. Following the above verification, it can be confirmed that the curve in the torso is at the solar plexus.

[0147] From these facts, it can be seen that the reason why the waist waistline is positioned higher after long-term wear of the present invention is because the above-mentioned "effect provided" has been achieved.

[0148] It is believed that the features of the present invention align the bones connected to the lower back and muscles such as the latissimus dorsi, gluteal muscles, intrinsic muscles, and extrinsic muscles, and position the waistline at the top.

[0149] Other Embodiments (1) The present invention uses a "V-shaped" waistline, which is suitable for tasks that involve a lot of movement of the lower back. It can accommodate movements and postures that involve heavy lower back movement and work that can be quite stressful. For example, training clothes and work clothes.

[0150] (2) By changing the double layer structure of the crotch portion of the present invention to a single layer structure and adjusting the leg length through the leg openings, the present invention can be used for clog pants with long legs (round overall shape) and short pants with short legs.

[0151] If you are concerned about the waistline shifting due to the weight of the fabric, you can use an adjuster on the lower abdomen side to adjust the waist size. However, it is recommended to choose a position that does not obstruct the movement of the ilium. See Figure 10.

[0152] (3) It is also possible to produce designs that reduce the overall area of ​​the fabric, as shown in Figure 12. This configuration is made possible by shortening the size of the armpits 5L, 5R and widening the length of the leg openings (thighs) 62L, 62R. One thing to note is to ensure that the weight of the fabric on the lower abdomen side is not heavier than the weight on the buttocks side. For example, the crotch area on the lower abdomen side may be shaved down to create a single layer crotch area.

[0153] (4) When the present invention is applied to a skirt, the skirt can be attached to the shorts. In that case, it is recommended to provide a part that can be opened and closed at the crotch area.

[0154] (5) By changing the size ratios, it can also accommodate clothing for infants, children, and adults of both genders.

[0155] It is also preferable to use it for clothes for newborns and babies.

[0156] This is because a baby's movements reflect an unconscious state and represent the natural movements of the human body. This natural movement means keeping your legs apart at all times, rather than closing your hips and keeping your legs together.

[0157] The baby unconsciously opens the hip joints, which in turn causes the legs to turn outward, and the knees are perceived to be bent. When a baby's clothing having a conventional lower body garment structure is worn on the body of a newborn or baby in a natural state, as described above, the natural movements of the human body are hindered.

[0158] For these reasons, we believe that the influence of clothing on infants and toddlers is extremely important in terms of their health.

[0159] (6) Clog pants are produced using the configuration of the present invention. The crotch portion of the double layer construction of this embodiment is made single layer. The length of the legs is long, reaching down to the ankles. (62L and 62R shown in Figure 1 are deleted, and the lengths of 6L, 6R, 61L, and 61R are extended.) In this embodiment, the LL and RR on the left and right lower abdomen sides are deleted, and the length of the legs from the leg openings is extended to the length of the ankles. Since the left and right leg fabrics are sewn together from the crotch position, the sewing positions of the left and right leg fabrics are slightly forward. (The fact that the stitching of the leg fabric is at the front can be seen when the weight and area of ​​the fabric at the back is large.) [Explanation of symbols]
