Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in conventional lower limb garments (lower limb garments described in Patent Document 1), a tightening section (composed of the upper parts of the above-mentioned (A) and (C) sections) is provided directly below the waist section that covers the wearer's waist, so as to wrap around the entire circumference of the wearer in a band-like manner, similar to a corset. By providing such a tightening section, the wearer's waist can be effectively supported and stabilized. However, because the wearer's vital parts are tightened all around directly below the waist section, it becomes difficult to move the legs.

[0006] This invention has been made in view of these circumstances, and aims to realize lower limb clothing that can support the wearer's waist while preventing difficulty in moving the legs. [Means for solving the problem]

[0007] To solve the above-mentioned problems, the first invention provides a lower limb garment comprising a waist portion covering the wearer's waist, a crotch portion extending downward from the waist portion, and a pair of crotch portions extending downward from the leg openings in the crotch portion, wherein the crotch portion and crotch portions are made of an elastic fabric, and on the left and right sides of the crotch portion and crotch portions, there are a pair of side tightening portions extending downward from the lower edge of the waist portion or near the lower edge, respectively, and on the left and right sides of the back of the crotch portion, respectively, there are portions that connect the waist portion and the side tightening portions and bring the side tightening portions inward. The garment for the lower limbs is equipped with a pair of back tightening parts that are pulled in a certain direction. On the right side of the back, the back tightening part is located to the upper right of the boundary that extends diagonally downward to the right from the center position in the width direction of the back at the lower edge of the waist, or to the right of the center position on the lower edge, and extends diagonally downward to the left from the boundary that extends diagonally downward to the left from the side tightening part. On the left side of the back, the back tightening part is located to the upper left of the boundary that extends diagonally downward to the left from the center position in the width direction of the back at the lower edge of the waist, or to the left of the center position on the lower edge, and extends diagonally downward to the left from the side tightening part.

[0008] The second invention is the first invention, wherein, when the lower limb garment is laid flat on a flat surface with its back facing upward, the upper end of the boundary is located at a distance of 0 cm or more and 6 cm or less from the center position, and the lower end of the boundary is located above the crotch where the pair of crotch sections branch, and is located at a distance of 8 cm or less from the position of the crotch in the vertical direction.

[0009] The third invention is that, in the first invention, when the lower limb garment is worn by the wearer, the upper end of the boundary is located near the sacroiliac joint of the wearer in the width direction of the lower limb garment, and the lower end of the boundary is located near the height of the greater trochanter of the wearer in the vertical direction of the lower limb garment.

[0010] The fourth invention is that, in the first invention, when the lower limb garment is laid flat on a flat surface with the back facing upwards, the right boundary of the back portion is curved so as to bulge upwards to the right, and the left boundary of the back portion is curved so as to bulge upwards to the left. [Effects of the Invention]

[0011] In this invention, a pair of side tightening sections are provided on the left and right sides of the crotch area, extending downward from the lower edge of the waistband or near the lower edge. This prevents the stretching of the fabric when the wearer puts on the lower leg garment from being suppressed by the side tightening sections. As a result, the wearer's left and right iliotibial bands are pressed more strongly inward compared to when there are no side tightening sections, making it more difficult for the force from the left and right legs to escape outward, and effectively supporting the wearer's waist. In addition, a pair of back tightening sections are provided on the left and right sides of the back of the crotch area, connecting the waistband and the side tightening sections and pulling the side tightening sections inward. This further presses the wearer's left and right iliotibial bands inward, providing even more effective support for the wearer's waist.

[0012] On the other hand, on the right side of the back, a boundary (boundary between the back tightening section and the non-tightening section) is provided, extending diagonally downward to the right from the center position in the width direction of the back at the lower edge of the waist section, or from a position to the right of the center position on the lower edge, to the right side tightening section, with the back tightening section located to the upper right of the boundary. On the left side of the back, a boundary (boundary between the back tightening section and the non-tightening section) is provided, extending diagonally downward to the left from the center position in the width direction of the back at the lower edge of the waist section, or from a position to the left of the center position on the lower edge, to the left side tightening section, with the back tightening section located to the upper left of the boundary. In this invention, the portion composed of the upper part of the pair of side tightening sections and the pair of back tightening sections does not include a band-shaped tightening section that covers the entire circumference of the wearer, and is less likely to hinder the wearer's leg movement. Furthermore, the pair of back tightening sections are located above the boundary that extends diagonally downward as described above, so as not to hinder the wearer's leg movement. According to the present invention, it is possible to realize lower limb clothing that supports the wearer's waist while preventing difficulty in moving the legs. [Brief explanation of the drawing]

[Figure 4] Figure 4 shows a cross-sectional view of the lower limb garment according to the embodiment, specifically the AA cutting position in Figure 2(A) (cross-sectional view of the fastening area, etc.). [Figure 5] Figure 5 is a rear view of the lower limb garment in a worn state according to another embodiment. [Modes for carrying out the invention]

[0014] The embodiments of the present invention will be described in detail below with reference to the drawings. Note that the following embodiments are examples of the present invention and are not intended to limit the scope of the invention, its applications, or its uses.

[0015] This embodiment is a lower limb garment 10 worn to cover the wearer's waist and lower limbs. The lower limb garment 10 is long in length (e.g., long leggings, long spats, long tights). Here, "waist" refers to the area between the lowest ribs and the gluteal crease that can be felt. The lower limb garment 10 is formed symmetrically on both the front and back sides. In this specification, "right side" refers to the right leg side, and "left side" refers to the left leg side.

[0016] As shown in Figures 1(A)-(C), the lower limb garment 10 comprises a waist portion 11 that covers the wearer's waist, a crotch portion 12 extending downward from the lower edge 11a of the waist portion 11, and a pair of crotch portions 13 extending downward from the leg openings in the crotch portion 12. Figures 1(A)-(C) omit the wearer's description, but show the lower limb garment 10 being worn by a wearer (a wearer who fits the size of the lower limb garment 10) in a worn state (a state in which the fabric stretches and fits the wearer).

[0017] In the lower limb garment 10, elastic fabric is used in the waist area 11, the crotch area 12, and the inseam area 13. This allows the lower limb garment 10 to fit snugly to the wearer's body and provide a comfortable fit. Alternatively, a band-shaped elastic (e.g., flat elastic) may be used in the waist area 11, and elastic fabric may be used in the crotch area 12 and the inseam area 13.

[0018] The waist part 11 is a part for preventing the lower body clothing 10 from slipping down, and a stretchable material is used. The waist part 11 is formed in a belt shape that covers the wearer's waist all around. The waist part 11 covers and tightens, for example, near the waist line, near the navel, or slightly below the navel. For the waist part 11, a fabric thicker than the fabric of the non-tightening part 23 of the upper thigh part 12 can be used, for example.

[0019] The upper thigh part 12 is a part that extends from the lower edge 11a of the waist part 11 to the crotch part 14 where a pair of lower thigh parts 13 branch off. The upper thigh part 12 covers the lower side of the wearer's lower abdomen and buttocks, etc. At the back surface part 12b of the upper thigh part 12, a central boundary part 15 that divides the right side part and the left side part extends from the center position C in the width direction of the lower edge 11a of the waist part 11 to the crotch part 14. Here, the "lower abdomen" is the part below the navel and above the crotch part 14.

[0020] A pair of lower thigh parts 13 are parts that branch into two hands from the lower end of the upper thigh part 12. Each lower thigh part 13 is formed in a tubular shape that extends downward with the crotch part 14 as the base. Each lower thigh part 13 covers the wearer's thigh part and lower leg part. Each lower thigh part 13 gradually becomes thinner as it approaches the lower side.

[0021] [Regarding the tightening part] A pair of side tightening parts 21, 21 are provided on the left and right side parts of the upper thigh part 12 and the lower thigh part 13 (the parts that cover the sides of the wearer's waist and thigh). Also, a pair of back tightening parts 22, 22 are provided on the left and right of the back surface part 12b of the upper thigh part 12. In FIGS. 1(A)-(C), the tightening parts 21, 22 are hatched to make it easier to grasp the range of the tightening parts 21, 22.

[0022] Here, the tightening parts 21, 22 are parts that apply a tightening force to specific parts of the wearer's body. The tightening parts 21, 22 have lower stretchability (elasticity) compared to the non-tightening parts (fabric parts other than the tightening parts 21, 22) 23 of the upper thigh part 12 and the lower thigh part 13.

[0023] The pair of side fastening sections 21, 21 are formed symmetrically. The side fastening sections 21 are formed in a band shape. The width of the side fastening sections 21 gradually decreases as it approaches the bottom, but it may also increase as it approaches the bottom, or it may have a uniform width. The average width of the side fastening sections 21 in the non-wearing state when the lower limb garment 10 is not worn (when the fabric of the lower limb garment 10 is not stretched) can be, for example, 8 cm to 15 cm.

[0024] The side fastening portion 21 extends downward from the lower edge 11a of the waist portion 11. Alternatively, the side fastening portion 21 may extend downward from the vicinity of the lower edge 11a of the waist portion 11. In other words, the side fastening portion 21 may be slightly away from the lower edge 11a of the waist portion 11. Here, "near" the lower edge 11a means within 3 cm of the lower edge 11a.

[0025] The lateral tightening portion 21 extends downward to a position beyond the position of the groin area 14 in the vertical direction (the position indicated by the dashed line in Figures 1(A)-(C)). Preferably, the lateral tightening portion 21 extends to a position that covers at least the upper part of the iliotibial band. The lateral tightening portion 21 may also extend to a position that covers the lower part of the iliotibial band (near the knee area 16 (see Figure 1(B))).

[0026] The pair of back fastening sections 22, 22 are formed symmetrically. The back fastening section 22 is formed in a roughly triangular shape. The back fastening section 22 connects the waist section 11 and the side fastening section 21 and pulls the side fastening section 21 inward. Each back fastening section 22 is demarcated by a boundary section 25, the waist section 11, and the side fastening section 21.

[0027] Here, the back portion 12b of the crotch area 12 is provided with a pair of boundary portions 25, 25 that demarcate the back tightening portion 22 and the non-tightening portion 23. In a rear view of the lower limb garment 10, the pair of boundary portions 25, 25 spread outward toward the bottom, forming a V-shape. The boundary portions 25 are made of an elastic cord material and exert a tightening force in the same or similar direction as the back tightening portion 22.

[0028] On the right side of the back portion 12b, the boundary portion 25 extends diagonally downward to the right from a position near the center position C in the width direction of the back portion 12b at the lower edge 11a of the waist portion 11, to the right side tightening portion 21. The boundary portion 25 is spaced to the right of the center position C. The right back tightening portion 22 is located to the upper right of the boundary portion 25. The right non-tightening portion 23 is located to the lower left of the boundary portion 25.

[0029] On the left side of the back portion 12b, the boundary portion 25 extends diagonally downward to the left from a position near the center position C in the width direction of the back portion 12b at the lower edge 11a of the waist portion 11, to the left side tightening portion 21. The boundary portion 25 is spaced apart to the left from the center position C. The left back tightening portion 22 is located to the upper left of the boundary portion 25. The left non-tightening portion 23 is located to the lower right of the boundary portion 25.

[0030] The position "closer" to the center position C on the lower edge 11a refers to a position on the lower edge 11a that is closer to the center position C than the middle of the section R3, which is one side (right or left) of the center position C on the lower edge 11a, when the lower limb garment 10 is laid flat on a flat surface with its back facing upward (as shown in Figure 2(A)). The flat laying state is when the lower limb garment 10 is stretched up, down, left, and right on a flat surface to minimize wrinkles.

[0031] Furthermore, as shown in Figure 2(B), the right boundary portion 25 may extend diagonally downward to the right from the center position C, and the left boundary portion 25 may extend diagonally downward to the left from the center position C.

[0032] Referring to Figure 2(A), the positions of the upper end (the end on the waist portion 11 side) and the lower end (the end on the side tightening portion 21 side) of the boundary portion 25 in a laid-down state will be described. In a laid-down state, the upper end (inner end) of the boundary portion 25 is at a distance X (see Figure 2(A)) from the center position C in the width direction of the back portion 12b that is 0 cm or more and 6 cm or less (preferably 2 cm or more and 5 cm or less). Also, in a laid-down state, the lower end (outer end) of the boundary portion 25 is located above the crotch portion 14, and the distance Y (see Figure 2(A)) from the position of the crotch portion 14 in the vertical direction is 8 cm or less (preferably 5 cm or less).

[0033] When laid flat, the right boundary section 25 curves upwards and to the right, while the left boundary section 25 curves upwards and to the left. Also, the height dimension h of the boundary section 25 is slightly larger than the width dimension w of the boundary section 25.

[0034] Referring to Figure 3, the positions of the upper and lower ends of the boundary portion 25 when the lower limb garment 10 is worn by the wearer will be explained. When worn, the upper end of the boundary portion 25 is positioned in the width direction of the lower limb garment 10 near the sacroiliac joint 3, which connects the ilium 1 and sacrum 2 of the wearer. In Figure 3, the area of ​​the sacroiliac joint 3 is shown with a thick line. Also, when worn, the lower end of the boundary portion 25 is positioned in the vertical direction of the lower limb garment 10 near the height of the greater trochanter 4 of the wearer. The height of the greater trochanter 4 is also near the lower end of the gluteus maximus muscle.

[0035] Furthermore, in the width direction of the lower limb garment 10, the area near the sacroiliac joint 3 includes the area within 1 cm to the left and right of both ends of the range R1 (see Figure 3) of the sacroiliac joint 3 in the width direction. Also, in the vertical direction of the lower limb garment 10, the area near the height of the greater trochanter 4 includes the area within 2 cm above and below the range R2 (see Figure 3) of the greater trochanter 4 in the vertical direction.

[0036] Referring to Figure 4, the cross-sections of the fastening sections 21 and 22 will be described. The fastening sections 21 and 22 consist of a first fabric 31 made of the same fabric as the non-fastening section 23 of the back portion 12b, and a second fabric 32 provided to stretch together with the first fabric 31. In Figure 4, the second fabric 32 is superimposed on the front side of the first fabric 31, but it may also be superimposed on the back side of the first fabric 31. The second fabric 32 is made of mesh fabric with many holes, but a fabric other than mesh fabric may also be used.

[0037] Here, the first fabric 31 of the side fastening section 21 and the first fabric 31 of the back fastening section 22 are connected via an elastic cord 26. The cord 26 constitutes the boundary between the side fastening section 21 and the back fastening section 22 or the back non-fastening section 23. Also, the first fabric 31 of the back fastening section 22 and the fabric of the non-fastening section 23 of the back section 12b are connected via a cord 25 that constitutes the boundary 25. Although not shown in Figure 4, the first fabric 31 of the side fastening section 21 is connected to the fabric of the front non-fastening section 23 via an elastic cord 27 (see Figure 1(B)). The cord 27 constitutes the boundary between the side fastening section 21 and the front non-fastening section 23.

[0038] The second fabric 32 of the side fastening section 21 is joined to the cord 26 at one end in the width direction and to the cord 27 at the other end in the width direction. The second fabric 32 of the back fastening section 22 is joined to the cord 26 at one end in the width direction and to the cord 25 at the other end in the width direction. Due to these connections, the second fabric 32 expands and contracts together with the first fabric 31.

[0039] The cross-sectional structure of the fastening sections 21 and 22 is not limited to the structure shown in Figure 4. The fastening sections 21 and 22 may be made of a single piece of fabric with lower elasticity than the fabric of the non-fastening section 23, or they may be made of three or more pieces of fabric.

[0040] [Effects of this embodiment, etc.] In this embodiment, a pair of side tightening sections 21, 21 are provided on the left and right sides of the crotch area 12 and crotch area 13, extending downward from the lower edge 11a of the waist area 11 or near the lower edge 11a, respectively. This suppresses the stretching of the fabric when the wearer puts on the lower limb garment 10. As a result, the wearer's left and right iliotibial bands, sacroiliac joints 3, and hip joints are pressed more strongly inward compared to when the side tightening sections 21 are not present, making it more difficult for the force from the left and right legs to escape outward, and effectively supporting and stabilizing the wearer's waist. In addition, a pair of back tightening sections 22, 22 are provided on the left and right sides of the back area 12b of the crotch area 12, respectively, connecting the waist area 11 and the side tightening sections 21 and pulling the side tightening sections 21 inward. This further presses the wearer's left and right iliotibial bands, etc., more strongly inward, providing even more effective support for the wearer's waist.

[0041] On the other hand, on the right side of the back portion 12b, the back tightening portion 22 is located to the upper right of the boundary portion 25 that extends diagonally downward to the right from a predetermined position on the lower edge portion 11a of the waist portion 11. On the left side of the back portion 12b, the back tightening portion 22 is located to the upper left of the boundary portion 25 that extends diagonally downward to the left from a predetermined position on the lower edge portion 11a of the waist portion 11. In this embodiment, the portion formed by the upper part of the pair of side tightening portions 21, 21 and the pair of back tightening portions 22, 22 does not include a band-shaped tightening portion that covers the entire circumference of the wearer, and is less likely to hinder the wearer's leg movement. In addition, the pair of back tightening portions 22, 22 are located above the boundary portion 25 that extends diagonally downward outward so as not to hinder the wearer's leg movement. The boundary portion 25 is also curved so as to bulge outward diagonally upward. According to this embodiment, it is possible to realize a lower limb garment 10 that can effectively support the wearer's waist while suppressing difficulty in moving the legs.

[0042] Furthermore, in this embodiment, the lower end of the back tightening portion 22 is located near the lower end of the gluteus maximus muscle, and the boundary portion 25 along the inner edge of the back tightening portion 22 extends diagonally along the direction of the muscle fibers of the gluteus maximus. The side tightening portion 21 is pulled in an inward diagonal upward direction (direction of the black-filled arrow in Figure 3) along the direction of the boundary portion 25 (direction of the muscle fibers of the gluteus maximus). Therefore, the gluteus maximus can be effectively supported. Here, the gluteus maximus is connected to the latissimus dorsi on the opposite side via the lumbar fascia. The gluteus maximus is connected to the large muscle called the latissimus dorsi. Therefore, by effectively supporting the gluteus maximus, the wearer's waist and other areas can be effectively supported.

[0043] [Other embodiments] In the above-described embodiment, the lower limb garment 10 may be a short-length garment (such as short leggings) that does not cover the wearer's lower limbs.

[0044] In the above-described embodiment, the rear tightening portion 22 may be formed in a strip shape, as shown in Figure 5. Figure 5 shows hatching applied to the tightening portions 21 and 22.

[0045] In the above embodiment, the pair of side fastening portions 21, 21 do not have to be symmetrical. Similarly, the pair of rear fastening portions 22, 22 do not have to be symmetrical.

[0046] In the above-described embodiment, when laid flat, each boundary portion 25 may be straight.

[0047] In the above-described embodiment, the lower side of each boundary portion 25 in the crotch area 12 is composed only of non-tightening portions 23, but tightening portions that do not hinder leg movement may also be provided.

[0048] In the embodiment described above, the back fastening portion 22 may be made of an elastic cord material instead of fabric. Such a cord material is provided along the boundary portion 25 in the area of ​​the back fastening portion 22. [Industrial applicability]
