Abstract
Description
[Technical Field]
[0001] The present invention relates to lower body clothing 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 Figure 13. Other garments, like those in Figure 14, have the same structure as Figure 13 but use a fabric area that is smaller than the original dimensions of the human body.
[0003] In addition to the above-mentioned configuration, some leg openings have a narrowed shape. Furthermore, some leg openings have elastic strings around them.
[0004] Known lower body clothing (Patent Document 1) includes lower body clothing such as pants and girdles that lift and correct the hips without flattening the roundness of the buttocks, creating a well-defined hip line.
[0005] As shown in FIG. 2, the inner surface of the back-side main body 14 is provided with a patch 20 formed by connecting a pair of triangular left and right pieces of cloth 21, 22 at 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 sides of the left and right pieces of cloth 21, 22 and the hanging edges 21b, 22b along the gluteal cleft, while the slanted 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 slanted 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, with the portions along the hanging edges 21b, 22b serving as tightening force portions 23 and the portions on the slanted edges 21c, 22c sides serving as weak tightening force portions 24.
[0006] In the publicly known lower body garment (Patent Document 2), there is a women's underwear with a thick bottom 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 must be curved in the conventional pattern, which corresponds to the end of the body, is made into a double structure by creating a pattern that can be directly changed, 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 laterally, relieving unreasonable constraints on the movement of the lower abdomen, and when the buttocks move significantly due to sitting or bending forward, the back body stretches vertically, relieving unreasonable constraints on the movement of the buttocks, thereby reducing fatigue and improving athletic functionality while eliminating excessive looseness.

[0011] [Patent Document 2] Japanese Patent Application Publication No. 11-350206
[0012] [Patent Document 3] Japanese Patent Application Publication No. 7-207502 Summary of the Invention [Problem to be solved by the invention]
[0013] Conventional lower body clothing has been invented and devised, as in the above-mentioned Patent Documents 1 to 3, to provide hip lift, a comfortable fit, exercise functionality and comfort.
[0014] In the past, lower body clothing such as pants and girdles have been invented and designed to lift and correct the hips without flattening the roundness of the buttocks, and to create a well-defined hip line, as in the above-mentioned Patent Documents 1 to 3.
[0015] However, conventional lower body clothing has the problem of causing a forward-leaning posture, which can lead to back pain and other discomfort.
[0016] These factors have a negative impact on the human skeleton, muscles, and blood circulation.
[0017] Furthermore, conventional lower body clothing such as trousers and shorts have leg openings, but these have drawbacks for the human body. For example, when walking, the legs are constantly moving and the pelvis and gluteal muscles (gluteus maximus, gluteus medius, gluteus minimus, etc.) are active, and 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, 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 body. This pressure and strain, along with the weight, passes through the ilium and down from the back to the abdomen, causing inconvenience.
[0020] The lower back is essentially the center of the human body and is most affected by the upper and lower body.
[0021] However, some conventional lower body garments are designed to place strain or pressure on the waist, which has adverse effects on the bones and muscles of the upper and lower body.
[0022] Some conventional lower body garments use elastic strings around the entire waistline. Depending on the movement of the body and the tilt of posture, the elastic string places a load on both sides of the pelvis that is tilted up and down. It is thought that the load is greater on the side that is higher up.
[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 structure that aims to minimize the impact on the human body. [Means for solving the problem]
[0025] In order to solve the above problems, one embodiment of the lower-body clothing according to the present invention is a lower-body clothing that is symmetrical when viewed from the front, with the left and right armpits shaped to extend downward and outward, the area of the buttocks fabric being larger than the area of the lower abdominal fabric, the leg opening angle of the front part relative to the armpits being larger than 90 degrees, the leg opening of the back part continuing from the lower end of the armpits towards the back, and the leg opening angle of the back part relative to the armpits being larger than the leg opening angle of the front part.
[0026] In one embodiment of the present invention, the lower abdomen fabric and the buttocks fabric are configured so 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 of the left and right side portions and the lower leg openings are made of only a stretchable knit fabric.
[0028] In one embodiment of the present invention, the lower-body garment is composed of left and right pants, which are symmetrical, and have a left lower abdominal line and left buttocks line, and a right lower abdominal line and right buttocks line that extend 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, and the buttocks fabric waist along the left and right waistlines.
[0032] In one embodiment of the present invention, the length range of the elastic string is configured such that the length of the buttocks waist is longer than the length of the lower abdomen waist. [Effects of the Invention]
[0033] The V-shaped waistline and fabric weight shifting design of the present invention reduces pressure on the lower back from above and from the sides. This allows the natural movement of the pelvis (ilium) to be freely moved. The positive effect of the "V-shaped" waistline on the human body is that it reduces the pressure on the lumbar vertebrae and pelvis even when sitting or bending forward.

[Figure 14] It is a conventional lower body garment (shorts with a fabric area smaller than the actual size of the human body). DETAILED DESCRIPTION OF THE INVENTION
[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 these figures, the waistline of the present invention has 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 examining the daily movements of the human body," and therefore, the present embodiment based on the examination will be described below.
[0037] 《Point of focus》 This invention focuses on the causes of forward-leaning posture and lower back pain, and devise lower body clothing to alleviate discomfort that originates in the lower back. It is based on the shape of the waistline and the shifting of fabric weight.
[0038] When making lower body clothing, we believe that the most important thing to consider is the impact on the waist, which is the center of the human body. The relationship between the waistline of lower body clothing and the "waist" is always close and can be considered to be an unavoidable relationship.
[0039] For these reasons, the object of lower body clothing for preventing lower back pain is to provide a configuration that can accommodate the movement of the "lower back" and can alleviate 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 of the wearer during daily work or activities, and it is considered appropriate to use a stretchy knitted fabric that can accommodate any posture.
[0041] Furthermore, from the 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 devised a configuration that can avoid the influence on the waist and reduce pressure and strain on the skeleton and muscles.Furthermore, a configuration with a generous fabric area for lower body clothing that does not put strain on the human body has been devised.
[0043] "verification" (1) Let's examine the shape of the human body's muscle fibers and waistline. The lower back is the center of the human body and is thought 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 longitudinal (longitudinal) muscle fibers. When the human body moves, their movement is considered active.
[0045] Considering this human anatomy, it was necessary to devise a shape for the waist, which is the center of the human body, that would conform to the human anatomy 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 employs a "V-shaped" waistline that follows the vertical flow of muscle fibers, which is expected to reduce resistance in the vertical direction. See Figure 11.
[0048] The "V-shaped waistline" of this embodiment can reduce pressure and strain on the latissimus dorsi muscles, 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 structure of the natural movement of the pelvis.
[0050] For example, when the human body moves from an upright to a sitting position, the sacrum normally begins to gradually arch downward and forward. See Figure 10 for an image of the human body. In conjunction 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 from side to side (rounding) at the same time. See Figure 11.
[0053] Furthermore, when sitting with the thighs facing inward, such as with the knees together, the lower part of the pelvis spreads out to the left and right (in a V 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, the structure of the pelvis is thought to be 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. Taking these points into consideration, it may be difficult to take a large step forward from the thigh by imagining that the pelvis is moving in the opposite direction of the arrow. See Figure 10, image of the human body. This is thought to be the reason why people take short steps when walking, rather than long ones.
[0055] For these reasons, the present invention is designed with an emphasis on a fabric area 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 is designed with consideration given to the fabric area in the front and back.
[0056] The present invention is designed to take into consideration such up-down and left-right movements of the ilium and buttocks, and is primarily designed to determine the area of the buttocks fabric.
[0057] This specified area does not put strain on the skeleton or muscles that make up the human body structure, and combined with the "V"-shaped waistline, it is expected to help restore and maintain joint spaces (gaps between bones). Furthermore, this configuration is expected to help prevent lower back pain.
[0058] Furthermore, the pressure from behind the back, which is caused by the small area of fabric in the buttocks area and the horizontal waistline, which are common in conventional lower body clothing, can be reduced. See Figure 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 and thigh, which are connected to the pelvis as mentioned above, 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] Therefore, we believe that a large, wide 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, and the range of motion of the femur and thigh is not obstructed, allowing the joint cavity to be maintained. For example, when doing leg-splitting while wearing conventional lower body clothing, even if you try to spread your thighs outward, they may end up being pulled inward. In contrast to this, the present embodiment has a "widening shape" that allows the thighs to be directed outward significantly.
[0063] Furthermore, if any material that tightens around the legs, not just elastic laces, is used for the leg openings, the strength of such material will cause the lower abdominal fabric and buttocks fabric to be pulled downward. When the fabric of the front and back of lower body clothing is pulled towards the leg openings and crotch area, the waistline also drops downward, causing the position of 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 to 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 also be formed as shown in Figure 12.
[0067] (4) We will 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 the two ends of this cut elastic string, it will form a circle (ring). The properties of the elastic string change as it shrinks (from the outside to the inside) towards the center of the circle (ring).
[0069] Careful consideration must be given to the impact on the human body of using elastic strings with such characteristics around the entire waistline.
[0070] This is because the effect of an elastic string with these properties on the human body changes to a contracting action towards the center of the body.
[0071] For example, the stronger the elasticity, the greater the strain 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 becomes 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 downward, rounded movement.
[0073] Even when in an upright position, the natural state of the human body is for the lower back to bend downwards while taking on a rounded shape, rather than arching the back.
[0074] However, the elastic string in a circular shape that is used around the entire waistline puts pressure on the natural position of the human body, placing a great strain on the central waist area.
[0075] In view of these points, in this embodiment, the waistline side portions 30 that come into direct contact with the ilium are configured not to include strings or the like, including but not limited to elastic strings. Also, the positions of the elastic strings at the waistline are shown by F and B. See Figures 3 and 4 (vertical stripes).
[0076] The present invention is expected to prevent herniated discs by combining a "V-shape" waistline with no elastic strings at the waistline 30.
[0077] Furthermore, this configuration can also reduce the impact on the ilium and femur that may be caused by movement or tilting of the posture, which may affect the tilted pelvis on both sides.
[0078] (5) We will examine the structure and weight of the fabric that presses on the waist, 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, as if holding it down from above.
[0080] Therefore, it can be said that a horizontal waistline, which is 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 on the front and back places a heavy pressure on the loaded ilium.
[0082] In this embodiment, the area of the buttocks cloth is larger than the area of the lower abdomen cloth. The reason for this is that the buttocks crotch widths 31L, 31R are sewn together with the lower abdominal crotch widths 3L, 3R, and by pulling, 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 fabric weight between the front and back of the lower body garment and by using the "V-shape" in combination, so it is designed to be able to respond to the movements of the human body. Therefore, the uncomfortable feeling of pressure and strain on the lumbar vertebrae 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. (Hereafter, "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 downward. The front leg angle 1θ and the back leg angle 2θ are determined by the lower abdominal line inclination angle α, the buttocks line inclination angle β, and the width of the crotch area. (The width of the crotch area will be discussed later.) Therefore, no measurements are required when creating the left and right pants. In this embodiment, the normal angle is approximately 100 degrees for 1θ and approximately 135 degrees for 2θ.
[0086] 1 and 2 are plan views of symmetrical 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 achieve a "V-shape," the sizes of the waistlines 1L and 1R are set based on a human hip size that is larger than the actual waist depression. By using your hip size as a guide, you can avoid tightness around the waist when wearing the garment. Also, by using the top of your buttocks as a base size, you can put it on and take it off without any problems.
[0088] In addition, it is preferable that the vertical width of the waistlines 1L and 1R be set to a dimension that matches the vertical width of the elastic strings that will be attached later.
[0089] <Wait> The side lines 5L and 5R are lines that descend vertically from the center of the waistlines 1L and 1R. In this embodiment, it is preferable that the length of the armpits 5L and 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, tilt angle> By setting the inclination angles α and β shown in Figures 1 and 2 to follow the curves of the abdomen and buttocks, pressure on the human body caused by changes in pelvic movement can be reduced.
[0091] The lower abdominal lines 2L, 2R and the buttock lines 4L, 4R are lines that extend downward and outward at an inclined 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 abdominal line inclination angle α is preferably smaller than the buttock line inclination angle β. However, this does not apply to certain body types (e.g., pregnant women).
[0094] <Buttocks line> The buttock lines 4L, 4R are inclined at an angle β with respect to the waistlines 1L, 1R, and the length from the lower end of the buttock waistlines 11L, 11R to the crotch position is set. In this embodiment, the length of the buttocks lines 4L and 4R is preferably long enough to enclose the buttocks and cover the crotch area (taking into consideration the up / down and left / right movement of the buttocks).
[0095] <Lower abdomen 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 and down and left and right movements of the lower abdomen.)
[0096] The length of the buttock lines 4L and 4R is set to be longer than the length of the lower abdominal lines 2L and 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 areas LL and RR extending below the lower abdominal lines 2L and 2R shown in Figures 1 and 2, and the crotch areas 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 shape is positioned at the bottom of the drawing.
[0099] In this embodiment, the widths of the lower abdominal crotch regions LL, RR and 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 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 and RR and the buttock crotch regions LL1 and RR1 shown in FIGS. 1 and 2 are based on the lengths of the buttock crotch vertical widths (median lines) LX1 and RX1.
[0101] Furthermore, the vertical widths LX1 and RX1 of the crotch area of the buttocks need to be set in advance by the leg openings (back area) 61L and 61R, which will be described later. Therefore, if the following steps are performed in advance, the vertical widths LX1 and RX1 of the crotch area of the buttocks can be easily set.
[0102] The length of the leg openings (back area) 61L, 61R is determined by connecting the crotch widths 31L, 31R at the lower ends of the buttock lines 4L, 4R with the leg openings (thigh area) 62L, 62R. (The leg openings will be described later.)
[0103] At this point, the buttocks lines 4L and 4R are provided with buttocks crotch widths 31L and 31R and buttocks crotch length widths LX1 and RX1.
[0104] Here, work is added to make the buttock crotch areas LL1, RR1 and the lower abdomen crotch areas LL, RR overlapping with each other to form the same shape.
[0105] To provide the shape of the crotch area LL and RR at the bottom of the lower abdominal line 2L and 2R, 1. Align the line that will become the midline of the crotch area. Place the crotch width 31L and 31R at the bottom of the lower abdominal line 2L and 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 lengths as the vertical widths LX1 and RX1 of the crotch area of the buttocks prepared in the previous step are set as the vertical widths LX and RX of the crotch area 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 crotch sutures LP and RP and the lower abdominal crotch leg openings LZ and RZ are determined. At the same time, the lengths of the buttock crotch seams LP1 and RP1 and the buttock crotch leg openings LZ1 and 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 provided to the left and right pants L, R.
[0108] The crotch width 3L, 3R on the lower abdomen side determined by these steps is connected to the bottom ends of the armpits 5L, 5R to set the front leg openings 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 side portions 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 side portions.
[0110] The lower ends of the waist regions 5L and 5R are used as reference points, and the leg openings are set on the lower abdominal 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. It is also 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 leg openings (thighs) 62L, 62R are preferably of a length that takes into consideration the range of motion of the thighs.
[0112] The length of the leg openings (back portion) 61L, 61R is determined by connecting them to the leg openings (thigh portion) 62L, 62R and the crotch widths 31L, 31R. In addition, the leg openings (front portion) 6L, 6R are determined by connecting them to the leg openings (thigh portion) 62L, 62R and 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 taking into consideration the range of motion of the thighs, but the size of the fabric area covering the buttocks can also be adjusted. See Figure 12.
[0114] <Manufacturing method> In this embodiment, the left pants L and right pants R shown in Figures 1 and 2 are sewn together, and the crotch areas LL and RR of the lower abdomen and the crotch areas LL1 and RR1 of the buttocks are sewn together to form a uniform outer shape.
[0115] The stitching of the crotch area is a double structure in which the crotch areas LL and RR of the lower abdomen are on the inside and the crotch areas LL1 and RR1 of the buttocks are overlapped on the outside.
[0116] Elastic strings or the like 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 thread a string through the lower abdomen waist F above the waist 8 of the lower abdomen fabric and the buttocks waist B above the waist 9 of the buttocks fabric, which are sewn with a bag stitch, as shown in Figures 3 and 4, 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 elastic strings, woven elastic strings, mesh elastic strings, and stretch lace strings. (The strength of all types is not uniform.) In this embodiment, normal strength (medium) is preferred. 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 shown in FIG. However, the most optimal range is to take into consideration the range of motion of the ilium. The lower abdominal waist F of the elastic cord 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, forming the midline of the lower body garment of this embodiment. <Lower abdominal and buttock sutures>
[0121] The right buttock waistline 11R and right buttock line 4R of the right pants R shown in Figure 2 are sewn together with the left buttock waistline 11L and left buttock line 4L of the left pants L shown in Figure 1.
[0122] The right lower abdominal line 12R and the right lower abdominal line 2R of the right pants R shown in Figure 2 are stitched together with the left lower abdominal line 12L and the left lower abdominal line 2L of the left pants L shown in Figure 1.
[0123] After the previous stitching 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 the lower abdominal fabric waist 8 and buttock fabric waist 9 shown in Figures 3 and 4 are lowered downward, which acts to reduce the burden on the lower back.
[0124] Next, the left crotch longitudinal width LX and the right crotch longitudinal width RX on the lower abdominal side of the crotch midline shown in FIG. 8 are sutured. See Figure 5. The configurations of Figures 5 and 9 are sewn together to form the configuration of Figure 8.
[0125] <Crotch stitching> The structure shown in Figure 5 allows for the aforementioned weight shift of the fabric due to the stitching in the crotch area, as shown in Figure 6, and also stabilizes the "V-shaped" waistline.
[0126] The trapezoidal crotch sections shown in Figures 1 and 2 are overlapped, with the left crotch section LL on the lower abdomen side and the right crotch section RR on the lower abdomen side facing inward, and the left crotch section LL1 on the buttocks side and the right crotch section RR1 on the buttocks side facing outward. (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 on the outside, 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] Successive stitches are applied to each of the overlapping ends. Suturing the left groin leg LZ on the lower abdomen on the groin side and the left groin leg LZ1 on the buttocks. Suturing the right groin leg closure RZ on the lower abdomen on the groin side and the right groin leg closure 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 in the lower abdomen on the buttocks side and the right crotch suture RP1 on the buttocks. The above stitching completes 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 end centers of the lower abdomen fabric 10 and the buttocks fabric 20 are overlapped and the crotch area is sewn together causes the buttocks fabric 20 to pull on the lower abdomen fabric 10, allowing the weight of the fabric 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, and its range lies within the range of the left side 5L and the right side 5R. The buttocks fabric 20 shown in FIG. 4 has a buttocks fabric waist 9 at its upper end, and its range is 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 of only stretchable knitted fabric. Additionally, the waistline side portions 30 shown in Figs. 3 and 4 are also made of only stretchable knitted fabric. This also reduces the strain on the armpits mentioned above.
[0132] In addition, the design, which does not use elastic strings, etc., helps to reduce the possibility of the waistline shifting significantly downward due to the shape of the leg openings or strings, etc., and is also expected to reduce the strain placed on the lower back from above.
[0133] <Attaching an elastic string, etc.> After the left and right pants have been sewn together, elastic strings are attached to the lower abdominal waist F and the buttocks waist B as shown in Figures 3 and 4. It is also possible to sew the waist line into a bag stitch and pass the strings through it, and it is also possible to sew it at the lower abdomen waist F and buttocks waist B positions.
[0134] In this embodiment, the length of the attached string is determined 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, works to prevent stress from being placed on the waistline side portions 30 shown in Figures 3 and 4, allowing the waist size to be adjusted only at the lower abdominal waist F and buttocks waist B, making it easier to put on and take off. As shown in Figure 6, the waistlines 1L and 1R are larger than the depression in the lower back, but this prevents the garment 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 relaxation time when spending time unconsciously. Mainly pajamas and sweatsuits.
[0138] The clog pants produced in the other embodiment are worn and the legs are opened in the same manner as described above. Unlike pants made with conventional lower body clothing, the fabric does not bunch up when you spread your legs, and there is no feeling of pressure on the groin or hip joints.
[0139] Furthermore, even though I was trying to spread my legs outward, I didn't feel any sense of correction from the fabric that would force my knees inward, and I was able to spread my legs wide.
[0140] Taking these points into consideration, when making a long skirt or the like, it is preferable to take into account the movement of the thighs 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 this invention continuously for a long period of time, the waistline is positioned higher than before wearing this invention (closer to the solar plexus).
[0144] In addition, the obi belt for the traditional Japanese kimono (traditional Japanese clothing) is tied around the waist, covering the solar plexus. (How to wear a women's kimono)
[0145] When we examine these two points, we find that the natural position of the waist of the human body is around the solar plexus.
[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 wearing the present invention for a long period of time is that 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] Another embodiment (1) The present invention employs a "V-shaped" waistline, making it suitable for tasks involving a lot of movement of the lower back. It can accommodate movements and postures that involve intense lower back movement and work that places a heavy burden on the lower back. For example, training clothes and work clothes.
[0150] (2) By changing the double-layered crotch structure of the present invention to a single-layered 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) As shown in Figure 12, it is also possible to produce a design that reduces the overall area of the fabric. This configuration is made possible by shortening the size of the side portions 5L and 5R and widening the length of the leg openings (thigh portions) 62L and 62R. One thing to note is that we recommend making sure 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 off 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 this case, it is recommended to provide an opening and closing part in the crotch area.
[0154] (5) By changing the size ratio, it can accommodate clothing for infants, children, and adults of both genders.
[0155] It is also suitable for use in clothing 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 involves keeping your legs apart at all times, rather than closing your hip joints and keeping your legs together.
[0157] The baby unconsciously opens the hip joints, and in this movement, the legs are turned outward, and the knees are perceived as being bent. When baby clothes with the conventional lower body garment structure are worn on the natural body of a newborn or baby, as described above, the natural movements of the human body are hindered.
[0158] For these reasons, we believe that the influence of clothing on babies from infancy is very important in terms of their health.
[0159] (6) Sabot pants are produced from 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. (In Figure 1, remove 62L and 62R, and extend the lengths of 6L, 6R, 61L, and 61R.) In this embodiment, the LL and RR on the left and right lower abdomen sides are deleted, and the length of the leg from the leg opening is extended to the length of the ankle. Since the left and right leg fabrics are sewn together from the crotch position, the stitching positions of the left and right leg fabrics are slightly forward. (The stitching of the leg fabric is located at the front, which can be confirmed by the weight and area of the fabric at the back being larger.) [Explanation of symbols]
