Description

[Technical Field]

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

[0002] Conventionally, crotch garments or lower-body garments have been known that have a structure in which a separate fabric (textile) is layered over the front of the main body. For example, Patent Document 1 discloses a crotch garment equipped with a thermal fabric that has higher heat retention than the main body fabric. The thermal fabrics, one on each side, cover an area known as Scarpa's triangle, which is surrounded by the inguinal ligament, adductor longus, and sartorius muscles, providing localized warmth to the area. Another known configuration, such as the lower-body garment described in Patent Document 2, includes right and left abdominal belts joined to the main fabric at the left and right sides of the torso to cover the abdomen, and a central abdominal belt 34 joined to the main fabric at the left and right sides of the torso, with the right, left, and central abdominal belts, each made of stretchable belt-like fabric, overlapping at the lower abdomen. This lower-body garment adjusts the tightening force acting on the wearer's abdomen. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-39849 [Patent Document 2] Japanese Patent Application Publication No. 2019-7095 Summary of the Invention [Problem to be solved by the invention]

[0004] Although the clothing described in Patent Document 1 has a thermal insulation material covering the Scarpa triangle, the groin area of ​​the human body is slightly recessed compared to other parts of the body, so the thermal insulation material may not adhere tightly to the groin area and may float away from the groin area. Furthermore, when the wearer moves their legs significantly while wearing the clothing, the skin around the hip joint stretches significantly, causing the thermal insulation material to stretch and opening up the knitted fabric, resulting in insufficient thermal insulation. As a result, the thermal insulation properties of the thermal insulation material may not be fully utilized, potentially resulting in a loss of warmth. Furthermore, the clothing described in Patent Document 2 has a different purpose, and the abdominal belts do not cover the groin area, so thermal insulation in the groin area cannot be expected.

[0005] The present invention aims to provide lower body clothing that maintains warmth by allowing heat-retaining components to easily fit closely to the groin area when worn and preventing the fabric of the components from stretching too much. [Means for solving the problem]

[0006] [1] A lower-body garment according to one embodiment of the present disclosure comprises a main body portion having a front portion, a back portion, and a crotch portion, and left and right hem portions provided below the front portion, back portion, and crotch portion and through which the wearer's legs are passed; and a thermal cloth portion provided on the skin side of the main body portion so as to overlap the front portion and the left and right hem portions, wherein the thermal cloth portion has left and right side edges extending vertically above the front portion, a crotch edge portion extending in an inverted U-shape that opens downward near the crotch portion, and left and right lower edges located in front of the left and right hem portions, and the thermal cover area of ​​the thermal cloth portion surrounded by the left and right side edges, the crotch edge portion, and the left and right lower edges covers at least the lower abdomen and left and right groin areas of the wearer, and the left and right side edges and crotch edge portion of the thermal cloth portion are connected to the main body portion, and the left and right lower edges of the thermal cloth portion are free from the main body portion.

[0007] According to the lower-body garment [1], when worn, the thermal cover region of the thermal fabric portion covers the wearer's lower abdomen and left and right groin regions. The thermal fabric portion is connected to the main body portion at the left and right side edges and crotch edges, but the left and right lower edges are separate from the main body portion. Therefore, even if a stretching force is applied to the thermal fabric portion or the wearer moves their legs significantly while wearing the garment, the left and right lower edges are pulled up and deformed toward the thermal cover region. Therefore, the fabric of the portions of the thermal cover region covering the left and right groin regions is less likely to be pulled (is prevented from stretching significantly) and easily fits into the depressions of the groin regions. In other words, the thermal fabric portion easily fits closely to the groin regions. Furthermore, because the knitting of the fabric in this portion of the thermal fabric portion does not spread too much, the original heat-retaining properties of the fabric are easily maintained. Due to these effects, the lower-body garment [1] can maintain warmth in the wearer's lower body, particularly around the groin region.

[0008] [2] In the lower-body garment described in [1] above, the warmth-retaining cloth portion may have an upper edge portion closest to the waist portion of the main body portion, and left and right side edges connected to the left and right ends of the upper edge portion may be curved to bulge out to the left and right sides as they extend downward, away from the front center position. If the left and right side edges of the warmth-retaining cloth portion are curved, when the lower-body garment is worn, the main body portion first stretches up and down, and the warmth-retaining cloth portion also stretches up and down in response, making the curves of the left and right side edges less pronounced than when the garment is laid flat, and causing the warmth-retaining cloth portion to deform toward the front center position. This provides secure coverage of the wearer's lower body, particularly the lower abdomen, and fits closely to the groin area, further maintaining warmth.

[0009] [3] The lower-body garment of [1] or [2] above may include a separate warming cloth part provided on the skin side of the main body part so as to overlap the rear part. The separate warming cloth part may cover at least the wearer's sacrum. With this configuration, the separate warming cloth part covers the wearer's sacrum, so that warmth can be maintained not only in the front part but also in the rear part (upper buttocks). [Effects of the Invention]

[0010] According to the present invention, the heat-retaining cloth portion easily fits closely to the groin area, and warmth can be maintained in the lower body, particularly in the area around the groin area. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated description will be omitted.

[0013] The basic configuration of pants 1 according to this embodiment will be described with reference to Figures 1 and 2. As shown in Figures 1 and 2, pants 1 are a girdle-type garment for the lower body. A wearer wears pants 1 over underwear such as shorts. Pants 1 are garments designed primarily for women, but the wearer's gender is not particularly important. Note that Figures 1 and 2 (as well as Figures 3 and 4) all show pants 1 according to one embodiment laid flat.

[0014] The pants 1 include a main body portion 2 made of a stretchable fabric. The main body portion 2 has a front portion 3 covering the wearer's abdomen (including the lower abdomen, described below), a back portion 4 covering the wearer's buttocks, a crotch portion 6 (also called a crotch portion), a waist portion 8, and left and right hem portions 7 extending downward from the front portion 3, back portion 4, and crotch portion 6. The front portion 3 and back portion 4 form a tubular shape that fits the wearer's lower body. The wearer's legs are passed through the left and right hem portions 7. The waist portion 8 is located, for example, slightly below the wearer's navel, but is not limited thereto. The height of the waist portion 8 (crotch depth) may be set as appropriate. The length of the hem portions 7 is also not particularly limited. The hem portions 7 terminate somewhere above the wearer's thighs in the vertical direction. In other words, the left and right hem portions 7 cover at least the upper parts of the wearer's thighs (their bases). In this specification, the "vertical direction" refers to the direction of the wearer's height.

[0015] The tubular portion consisting of the front portion 3 and the back portion 4 is joined by stitching, for example, at a front center seam (not shown) and a back center seam 4c (see FIG. 4). The front portion 3 and the back portion 4 may also be joined by a side seam. An inner thigh seam 9 is formed on the inside of each hem portion 7 (the portions facing each other). The position of the inner thigh seam 9 is not particularly limited.

[0016] The main body 2 is made of, for example, a warp-knitted fabric or a weft-knitted fabric extending in the vertical direction (up and down) or horizontal direction (left and right). Stretchable materials used for the main body 2 include, for example, two-way raschel, two-way tricot, two-way satin power net, and other warp-knitted fabrics, and weft-knitted fabrics such as rib knit and bare smooth. Fabrics with different stretchability or strength may be used for each part of the main body 2, or the entire main body 2 may be made of the same fabric. The configuration of the main body 2 is not limited to the above configuration. The parts may be joined by stitching, or may be joined by other means such as adhesive.

[0017] Next, with reference to Figs. 3 and 4, the configuration of the pants 1 related to its heat retention performance will be described. Figs. 3 and 4 show the pants 1 inside out. As shown in Fig. 3, the pants 1 include a front warmth cloth portion (warmth cloth portion) 10 provided on the skin side of the main body portion 2. The front warmth cloth portion 10 is provided so as to overlap the front portion 3 and the left and right hems 7 of the main body portion 2. The front warmth cloth portion 10 is provided at a lower position than the waist portion 8. In other words, there is a gap between the front warmth cloth portion 10 and the waist portion 8. A connecting cloth portion 15 is provided between the waist portion 8 and the front warmth cloth portion 10. Unlike the front warmth cloth portion 10, the connecting cloth portion 15 is made of a stretchable fabric similar to that of the main body portion 2. The connecting cloth portion 15 covers the wearer's umbilicus and the surrounding area.

[0018] The front warmth-retaining fabric portion 10 overlaps a part of the front portion 3, specifically an area that includes the front center and has a width in the left-right direction, and further overlaps the upper ends of the left and right hems 7 at the parts that correspond to the inner thighs. The front warmth-retaining fabric portion 10 is made of a stretchy fabric. For example, a brushed material that has excellent heat retention properties is used as the front warmth-retaining fabric portion 10. In the embodiment, the front warmth-retaining fabric portion 10 is made of a brushed free-cut warp-knit fabric, but is not limited to this.

[0019] The front warmth-retaining cloth portion 10 has a shape similar to that of a water bottle when viewed from the front. The front warmth-retaining cloth portion 10 has an upper edge 11 closest to the waist portion 8 of the main body portion 2, and left and right side edge portions 12 extending in the vertical direction on the front portion 3. The left-right distance between the pair of side edge portions 12 (the width of a front warmth-retaining cover region 16 described below) is longer than the left-right length of the upper edge portion 11. The front warmth-retaining cloth portion 10 also has a crotch edge portion 13 that extends in an inverted U shape and opens downward at a position close to the crotch portion 6, and left and right lower edge portions 14 that are located in front of the left and right hem portions 7.

[0020] The upper edge 11 extends in the left-right direction. The left and right (pair of) side edge portions 12 are connected to the left and right ends 11a of the upper edge 11 and curve downward, bulging out to the left and right sides from the front center position. The front warmth-retaining cloth portion 10 has its maximum left-right width at the portion of the side edge portion 12 where the bulge amount is greatest. The maximum width of the front warmth-retaining cloth portion 10 is, for example, at least 1 / 2 and less than 3 / 4 of the left-right width at the height of the crotch portion 6 of the main body portion 2 when laid flat. The lower end of the crotch edge portion 13 is connected to the upper seam line 9a of the inner thigh seam line 9.

[0021] The lower ends of the left and right side edges 12 coincide with the upper end points 14a of the left and right lower edges 14. In contrast to the curved side edges 12, the left and right lower edges 14 are each straight (or approximately straight) and form an inverted V shape. The lower end points 14b of the left and right lower edges 14 are connected to the inner thigh seam line 9 below the crotch edge 6. In other words, the lower end points 14b of the lower edges 14 are located below the crotch edge 13. The lower end points 14b of the lower edges 14 intersect with the upper seam line 9a of the inner thigh seam line 9.

[0022] According to the front warmth-retaining cloth portion 10, when the pants 1 are worn, a front warmth-retaining cover region 16 surrounded by the left and right side edge portions 12, the crotch edge portion 13, and the left and right lower edge portions 14 covers at least the wearer's lower abdomen and left and right groin regions A (see FIG. 5). As a result, when the pants 1 are worn, the front warmth-retaining cover region 16 warms the area around the wearer's lower abdomen.

[0023] Furthermore, in the front warmth-retaining cloth part 10 of this embodiment, the upper edge part 11, left and right side edge parts 12, and crotch edge part 13 are joined to the main body part 2. The left and right side edge parts 12 are joined to the main body part 2 over the entire area, for example, from the left and right end parts 11a of the upper edge part 11 to the left and right upper end points 14a of the lower edge part 14. The crotch edge part 13 is also joined to the main body part 2 over the entire U-shape (the seam line of the crotch part 6 and the crotch edge part 13 are aligned), and the area above the seam line 9a (the area between the lower end point 14b and the crotch edge part 13) is also joined to the main body part 2. The front warmth-retaining cloth part 10 is joined to the main body part 2, for example, by sewing. Note that the front warmth-retaining cloth part 10 may be detached from the main body part 2 at the upper edge part 11.

[0024] On the other hand, the left and right lower edge portions 14 of the front warming cloth part 10 are not joined to the main body part 2 and are free from the main body part 2. There are no joined portions (they are joined portions) throughout the entire area of ​​the left and right lower edge portions 14, i.e., from the upper end point 14a to the lower end point 14b of each lower edge portion 14, and the left and right lower edge portions 14 are free to move relative to the main body part 2.

[0025] The rear portion 4 also has a structure related to heat retention performance. As shown in FIG. 4, the pants 1 include a rear heat-retaining fabric portion (another heat-retaining fabric portion) 20 that is provided on the skin side of the main portion 2 so as to overlap the rear portion 4. The rear heat-retaining fabric portion 20 covers at least the wearer's sacrum. The rear heat-retaining fabric portion 20 is made of a stretchable fabric. As with the front heat-retaining fabric portion 10, the rear heat-retaining fabric portion 20 may be made of, for example, a brushed material that has excellent heat retention properties. More specifically, the rear heat-retaining fabric portion 20 is made of a brushed free-cut warp-knit fabric, but is not limited to this.

[0026] The rear warmth-retaining cloth portion 20 has a generally inverted triangular shape. The rear warmth-retaining cloth portion 20 has an upper edge portion 21 that extends in the left-right direction in the region overlapping the waist portion 8, and two side edge portions 22 that extend from left and right end portions 21a of the upper edge portion 21 toward the rear center seam line 4c. The upper edge portion 21 and the two side edge portions 22 that form each side of the triangle are joined to the main body portion 2, for example, over their entire areas. The rear warmth-retaining cloth portion 20 is joined to the main body portion 2, for example, by sewing.

[0027] According to the rear warmth-retaining fabric portion 20, when the pants 1 are worn, the rear warmth-retaining cover region 23 surrounded by the upper edge portion 21 and the two side edge portions 22 covers at least the sacrum of the wearer. As a result, when the pants 1 are worn, the rear warmth-retaining cover region 23 warms the area from the lower back along the waist to around the sacrum.

[0028] According to the pants 1 of this embodiment, when worn, the front warmth cover region 16 of the front warmth cloth portion 10 covers the wearer's lower abdomen and left and right groin regions A. The front warmth cloth portion 10 is connected to the main body portion 2 at left and right side edge regions 12 and crotch edge regions 13, but left and right lower edge regions 14 are separate from the main body portion 2. Therefore, even if a stretching force is applied to the front warmth cloth portion 10 when worn or if the wearer moves their legs significantly, the left and right lower edge regions 14 are pulled up and deformed toward the front warmth cover region 16 (see the shape of the lower edge regions 14 and the arrows in FIG. 5 ). Therefore, the fabric of the portion of the front warmth cover region 16 covering the left and right groin regions A is less likely to be pulled (stretched) and easily fits into the depressions of the groin regions A. In other words, the front warmth cloth portion 10 easily fits closely to the groin regions A. Furthermore, since the fabric of the front warmth-retaining fabric part 10 in that part is prevented from stretching too much, the stitches of the fabric do not widen too much, and the original heat-retaining properties of the fabric are more likely to be maintained.

[0029] In this regard, as shown in FIG. 6 , in the pants 100 according to the reference example, even though the front warmth cloth portion 210 is provided on the skin-facing side of the main body portion 200, the lower edge portion 214 is also joined (by stitching) to the main body portion 2, along with the crotch edge portion for the crotch portion 206. Therefore, when the pants 100 are worn, the position of the lower edge portion 214 is maintained downward together with the main body portion 2, and the original linear shape of the lower edge portion 214 is maintained. This causes the fabric around the left and right groin regions A to stretch and become taut, resulting in the fabric floating above the groin region A. The fit around the groin region A is also poor, and the fabric of the warmth cloth portion 210 stretches significantly, causing the stitches of the fabric to widen. For example, even if the same fabric as the front warmth cloth portion 10 according to the above embodiment is used for the front warmth cloth portion 210, the heat retention performance may be significantly reduced. According to tests conducted by the inventors, the thermal insulation rate of the front thermal fabric portion 210 of the thermal fabric used in the examples was originally 16%, but when the stretching during wear was replicated, the thermal insulation rate dropped to 11%. Such a sudden drop can be said to impair the inherent thermal insulation performance of thermal fabrics such as brushed materials. The pants 1 of this embodiment maintain warmth and are effective in preventing chills caused by air conditioning in the summer, for example.

[0030] Furthermore, while the front warming cloth portion 10, which has heat-retaining properties, covers the lower abdomen and groin area A, the connecting cloth portion 15 provided between the front warming cloth portion 10 and the waist portion 8 covers the upper part of the abdomen (around the navel). For example, using a moisture-absorbing and releasing fabric for the connecting cloth portion 15 has the effect of dissipating stuffiness. In this embodiment, a moisture-dissipating fabric is connected to the upper part of the front warming cloth portion 10, which warms the lower abdomen and groin area A, which need to be kept warm, while preventing heat from building up inside the pants 1, allowing for moderate warmth. In pants 1 intended for year-round wear, it is preferable to have a connecting cloth portion 15 made of a moisture-absorbing and releasing fabric to prevent stuffiness in hot seasons. In cold seasons such as winter, the warming cloth portion 10 may be configured to reach near the waist portion 8 of the pants 1.

[0031] Furthermore, due to the curved left and right side edges 12, when the pants 1 are worn, the main body stretches up and down first, and the warmth-retaining fabric portion stretches up and down accordingly, making the curve of the left and right side edges less pronounced than when laid flat, and causing the warmth-retaining fabric portion to deform closer to the front center. This securely covers the wearer's lower body, particularly the lower abdomen, and fits closely to the groin area A, further maintaining warmth.

[0032] Furthermore, since the rear warming cloth portion 20 covers the wearer's sacrum, warmth can be maintained not only in the front portion 3 but also in the rear portion 4 (upper buttocks).

[0033] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, the shape of the front warmth-retaining cloth part 10 may be changed as appropriate. As long as the front warmth-retaining cover region 16 covers the lower abdominal region and groin region A and the lower edge portion 14 is free and not joined to the main body part 2, the front warmth-retaining cloth part 10 may have another shape. The pair of side edge portions 12 may not bulge, and the left-right distance between the pair of side edge portions 12 (the width of the front warmth-retaining cover region 16) and the length of the upper edge portion 11 may be the same or approximately the same. The shape of the rear warmth-retaining cloth part 20 may also be changed.

[0034] The connecting cloth part 15 may be omitted. In this case, the front warmth-retaining cloth part 10 may extend to the vicinity of the waist part 8.

[0035] The rear warming cloth part 20, which is a warming part provided in the rear part 4, may be omitted. [Explanation of symbols]
