Description

Bottom clothing

The present invention relates to bottom clothing.

Some conventional bottom clothing has a gusset portion formed by a cut line that follows the shape of the crotch to improve the fit from the gusset portion to the leg portion. For the same purpose, there are some which are designed so that the gusset portion is three-dimensionally floated from the crotch. For example, in the trunks-type pants described in Patent Document 1, a fabric portion that supports a local part of a man is formed at the center ends of the left and right front bodies using a knit fabric, and folded inside, and the left and right front bodies are folded back. It is configured to be stitched in the vicinity.

JP-A-9-003701

When the gusset portion is formed by a cut line that follows the shape of the crotch, the gusset cut line may impair the comfort when worn. Further, in the configuration in which the gusset portion is floated from the crotch, the groin portion is likely to float, and it may be difficult to secure a feeling of close contact with the skin. In both configurations, the conventional bottom clothing has a problem that a feeling of pressure is generated around the groin when squatting or sitting.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a bottom garment that can reduce the feeling of pressure around the groin and enhance the fit when worn.

In order to solve the above problems, in a bottom garment according to one aspect, a main body part constituting a main part of a waist part and a pair of leg parts and a front part of the main body part extend vertically, and a leg part extends from the front part of the waist part. A front portion that constitutes a front center portion that reaches the inner hem portion, and in a developed shape, a waist portion side portion of the front end portion of the sewing portion with the main body portion is a sewing end portion of the main body portion with the front portion. The leg side part of the sewing end side with the main body part in the front part intersects the leg side part of the sewing end side with the front part of the main body part. The sewn end side of the front part and the sewn end side of the main body part are sewn so that the leg side part is twisted relative to the waist side part.

In this bottom garment, the leg part of the front part is sewn to the main body part in a state where the leg part is twisted with respect to the waist part, so that the leg part is three-dimensionally formed so as to face forward. With the legs facing forward, the feeling of pressure around the groin is reduced during squatting and sitting, and the fit when worn is enhanced. By increasing the fit when worn, it is possible to suppress the occurrence of hemming and collapse due to movement.

Further, the waist side portion in the front portion may have elasticity in the width direction, and the leg side portion in the front portion may have elasticity in the vertical direction. A fit feeling to the wearer's lower abdomen can be ensured because the waist side portion has elasticity in the width direction. In addition, the leg side portion is stretchable in the vertical direction, so that the fit of the wearer on the inner thigh can be ensured. Moreover, since the leg part side part in the front part is twisted with respect to the waist part part, the expansion / contraction direction changes from the width direction to the up-down direction as it goes below the front part. For this reason, a fit feeling to a wearer's crotch part is also raised.

Also, in the developed shape, the sewing end side of the front portion with the main body portion may be curved in a concave shape so as to include a connection point between the waist portion and the leg portion. By smoothly connecting the waist side portion and the leg side portion of the sewing end side in the front portion by the concave curved portion, the three-dimensional feeling of the leg portion can be suitably formed.

Further, in the developed shape, a straight line connecting the upper end and the lower end of the sewing center side on the front center side in the front part and a perpendicular line extending from the connecting point to the straight line are drawn, and sewing at the front part is performed from the intersection of the perpendicular line and the straight line. The angle θ formed by the tangent drawn toward the curved portion of the end side may be 40 ° to 60 °. The inclination of the leg portion toward the front can be adjusted by the angle θ. By making the angle θ in the range of 40 ° to 60 °, it is possible to suitably ensure a feeling of fit when worn.

This bottom garment can reduce the feeling of pressure around the groin and enhance the fit when worn.

The side-side sewn edge 25 has a concavely curved shape so as to include the connecting point P2.

The lower end side of the leg side portion 25 b is located on the side of the line connecting the side edge of the waist end side 21 and the lower end of the leg end side 24, and forms a collar shape with the leg end side 24. is doing. Thereby, the front part 3 is substantially L-shaped as a whole, and the extending direction of the leg part 3b of the front part 3 intersects the obtuse angle with respect to the extending direction of the waist part 3a. It has become. Further, a straight line L1 connecting the upper end and the lower end of the front sewing end side 22 of the front portion 3 is drawn, and a perpendicular line L2 from the connecting point P2 toward the straight line L1 is drawn, and the leg side from the intersection P3 of the perpendicular line L2 and the straight line L1. The angle θ formed by the tangent line L3 drawn toward the curved portion of the portion 25b is preferably 40 ° to 60 °. This angle θ is a parameter that determines the degree of forward inclination of the leg 5 described later.

FIG. 4 is a diagram showing a state of sewing between the main body portion and the front portion. When the front portion 3 having the above-described configuration is sewn to the main body portion 2, first, as shown in FIG. 4A, the waist side portion 25 a of the side sewn edge 25 in the front portion 3 is the main body. Sewing is performed along the waist portion 15a of the front sewn edge 15 of the portion 2. At this time, the extending direction of the leg part 3b of the front part 3 intersects the obtuse angle with respect to the extending direction of the waist part 3a. The portion side portion 25b intersects with the front sewing end side 15 in the main body portion 2, and the leg portion side portion 3b of the front portion 3 projects to the main body portion 2 side.

Next, the leg part 25b of the side sewing end side 25 in the front part 3 is sewn to the leg part 15b of the front sewing end side 15 in the main body part 2. At the time of this sewing, the leg part 3b of the front part 3 protruding to the main body part 2 side is twisted from the vicinity of the connection point P2 to the inner hem side, and the leg of the side sewing end side 25 in the front part 3 is twisted. The portion side portion 25b is sewn along the leg portion portion 15b of the front side sewing edge 15 in the main body portion 2. Thereafter, when the crotch sewing end side 23 of the front part 3 is sewn to the crotch sewing end side 13 of the main body part 2, as shown in FIG. 4 (b), one of the main body part 2 and the front part 3 is obtained. The side sewing is completed. The same sewing is performed on the other side of the main body 2 and the front portion 3, and the front sewing edges 22, 22 of the

front portions

3, 3 are sewn on the front center A side, and the

main body

2 , 2 are sewn together on the rear center B side to form the bottom garment 1 shown in FIGS. 1 and 2.

FIG. 5 is a diagram showing the effect of bottom clothing. As shown in FIG. 5 (a), in the bottom garment 101 according to the comparative example, the configuration of the main body 102 and the shape of the waist 104 are the same as those in the above embodiment, but the front 103 is in advance of the front center portion 107. It is formed according to the shape. The main body 102 and the front part 103 are sewn together without the leg part 103b of the front part 3 being twisted with respect to the waist part 103a. In such bottom clothing 101, the three-dimensional formation force by the front part 103 does not act, and the leg part 105 is formed right below.

On the other hand, in the bottom garment 1 according to the embodiment, as described above, the leg part 3b of the front part 3 is sewn to the main body part 2 in a state of being twisted with respect to the waist part 3a. In the bottom garment 1, a three-dimensional forming force is applied by the twist of the front portion 3, and as shown in FIG. 5B, the leg portion 5 is three-dimensionally formed so as to face the front. When the leg portion 5 faces forward, a feeling of pressure around the groin portion is reduced during a squatting operation or a sitting operation, and a fit feeling at the time of wearing is enhanced. By increasing the fit when worn, it is possible to suppress the occurrence of hemming and collapse due to movement.

Further, in the bottom garment 1, as a result of twisting the front part 3, the expansion / contraction direction of the front part 3 changes depending on the position, and the waist part 3a in the front part 3 has elasticity in the width direction, The side portion 3b has elasticity in the vertical direction. When the waist part 3a has elasticity in the width direction, it is possible to ensure a fit to the wearer's lower abdomen. Moreover, when the leg part side part 3b has a stretching property in the up-down direction, a fit feeling to a wearer's inner thigh part can be ensured. Since the leg part 3b in the front part 3 is twisted with respect to the waist part 3a, in the twisted part (in the vicinity of the connection point P2), the expansion / contraction direction increases in the vertical direction from the width direction toward the lower part of the front part 3. To change. For this reason, a fit feeling to a wearer's crotch part is also raised.

Further, in the bottom garment 1, in the unfolded state, the side sewn end edge 25 of the front portion 3 is curved in a concave shape so as to include a connection point P2 between the waist portion 25a and the leg portion 25b. By smoothly connecting the waist part 25a and the leg part 25b of the side sewn edge 25 in the front part 3 with the concave curved part, the three-dimensional effect of the leg part 5 can be suitably formed.

Furthermore, in the bottom garment 1, in the unfolded shape, a straight line L1 connecting the upper end and the lower end of the front sewn end side 22 in the front portion 3 is drawn, and a perpendicular line L2 from the connecting point P2 toward the straight line L1 is drawn. The angle θ formed by the tangent L3 drawn from the intersection P3 with L1 toward the curved portion is 40 ° to 60 °. The inclination of the leg 5 toward the front can be adjusted by the angle θ. By making the angle θ in the range of 40 ° to 60 °, it is possible to suitably ensure a feeling of fit when worn.

In the above embodiment, men's pants are exemplified as the bottom clothing, but the bottom clothing is a long type of pants, tights, steteco with the length of the left and right legs extending further downward regardless of whether the clothing is for men or women. It can be applied to other bottom clothing. Moreover, the low waist type (low rise type) in which a waist | hip | lumbar part is located below a wearer's navel line in a wearing condition may be sufficient.

FIG. 6 is a view showing a modified example of the developed shape of the main body portion and the front portion constituting the bottom clothing. The example of the figure is a developed shape of the main body portion 2 and the front portion 3 when applied to women's pants. In the case of women, it is not necessary to provide a bulge in the front center portion 7. Therefore, the front side sewing edge 22 of the front portion 3 is different from the developed shape shown in FIG.

FIG. 7 is a view showing another modified example of the developed shape of the main body portion and the front portion constituting the bottom clothing. The example of the figure is a developed shape of the main body portion 2 and the front portion 3 when applied to long-type pants. In the case of long-type pants, for example, the crotch sewn edge 13 of the main body 2 is gently curved inward. Moreover, the leg part edge 24 in the front part 3 is not provided, and the crotch sewing edge 23 is left and right between the lower end of the front sewing edge 22 and the lower edge of the side sewing edge 25. It extends. Further, the crotch sewing end side 23 has a shape that is gently curved downward.

Also in the configuration of these modified examples, the leg portion 5 is formed in three dimensions so that the front portion 3 is twisted by the twist of the front portion 3. When the leg portion 5 faces forward, a feeling of pressure around the groin portion is reduced during a squatting operation or a sitting operation, and a fit feeling at the time of wearing is enhanced. By increasing the fit when worn, it is possible to suppress the occurrence of hemming and collapse due to movement.

FIG. 8 is a view showing another modified example of the developed shape of the main body part and the front part constituting the bottom clothing. The example of the figure is a developed shape of the main body 2 and the front part 3 similar to FIG. 3, but is different from the form shown in FIG. 3 in that the front part 3 is divided into two vertically. In this embodiment, the front portion 3 is formed of an upper dividing member 26A and a lower dividing member 26B along a dividing line that obliquely connects the substantially center position of the front sewing end side 22 and the upper side of the side sewing end side 25. It is divided into The dividing line has a gently curved shape so as to be convex upward.

The upper divided member 26A is defined by a waist end side 21, a substantially upper half portion of the front sewing end side 22, an upper portion of the side sewing end side 25, and a divided sewing end side 27a along the dividing line. Has been. Further, the lower divided member 26B includes a substantially lower half portion of the front sewing end side 22, a crotch sewing end side 23, a leg end side 24, and a lower side of the side sewing end side 25 (excluding the upper portion). Part) and a divided sewing end side 27b along the dividing line. The front portion 3 is integrated by sewing the divided sewing end side 27a of the upper divided member 26A and the divided sewing end side 27b of the lower divided member 26B.

Even with such a configuration, similarly to the above-described embodiment, the leg portion 5 is formed in a three-dimensional manner so that the front portion 3 is twisted by the twist of the front portion 3. When the leg portion 5 faces forward, a feeling of pressure around the groin portion is reduced during a squatting operation or a sitting operation, and a fit feeling at the time of wearing is enhanced. By increasing the fit when worn, it is possible to suppress the occurrence of hemming and collapse due to movement. In addition, by dividing the front portion 3 vertically, the stretchability of the material can be easily changed between the upper divided member 26A and the lower divided member 26B. For example, by configuring the upper divided member 26A with a non- (hard) stretchable material, the front part 3 can have a function of pressing the lower abdomen of the wearer.

FIG. 9 is a view showing another modified example of the developed shape of the main body portion and the front portion constituting the bottom clothing. The example of the figure is different from the embodiment shown in FIG. 8 in that an extended portion 3c constituting the upper portion of the main body 2 (at least a part of the waist portion 4) is further provided in the upper divided member 26A. Yes. The configuration of the lower divided member 26B is the same as that shown in FIG.

In this example, the upper divided member 26A has a waist end side 21, a substantially upper half portion of the front sewing end side 22, and a divided sewing end side 27a, as in the case of FIG. On the other hand, instead of the upper side of the side sewn end edge 25, the upper divided member 26A has a substantially linear shape that continues to the upper extended waist part edge 28 that continues to the waist part edge 21 and the divided sewing edge 27a. A lower extending waist end edge 29, and a rear sewing end edge 30 extending vertically between a rear end of the upper extending waist end edge 28 and a rear end of the lower extending waist end edge 29. ing.

The upper extended waist part edge 28 is a part sewn to the upper end part 4a of the waist part 4, and is substantially linear. The lower extension waist part edge 29 has a shape along the waist part edge 11 of the main body part 2 and is sewn to the waist part edge 11 to constitute the waist part 4. In this configuration, the waist part edge 11 of the main body 2 is curved so as to be convex upward, and the lower extension waist part edge 29 is correspondingly curved upwardly concavely. It has become. The lower extending waist part edge 29 is smoothly continuous with the divided sewing edge 27a. Further, the lower extending waist portion end side 29 is sewn on the side splitting of the lower divided member 26B by sewing of the divided sewing end side 27a of the upper divided member 26A and the divided sewing end side 27b of the lower divided member 26B. The lower part of the edge 25 continues smoothly. The rear sewing end side 30 is substantially linear, and is continuous with the rear sewing end side 12 of the main body 2 by sewing the main body 2 and the front portion 3. The rear sewing end side 30 is sewn to the rear sewing end side 30 of the other front portion 3 at the rear center B.

Even with such a configuration, similarly to the above-described embodiment, the leg portion 5 is formed in a three-dimensional manner so that the front portion 3 is twisted by the twist of the front portion 3. When the leg portion 5 faces forward, a feeling of pressure around the groin portion is reduced during a squatting operation or a sitting operation, and a fit feeling at the time of wearing is enhanced. By increasing the fit when worn, it is possible to suppress the occurrence of hemming and collapse due to movement. Further, by providing the extended portion 3c on the front portion 3, the lower extended waist portion 29 and the waist portion 11 are sewn together, particularly when the elastic tape is not disposed on the upper end portion 4a of the waist portion 4. The feeling of wearing the bottom garment 1 can be further improved by forming a restriction on the portion. In the form shown in FIG. 9, the front part 3 does not necessarily need to be divided, and the waist part 3a, leg part 3b, and extension part 3c may be formed in advance as an integral member. In the form shown in FIG. 9, the extended portion 3 c extends to the rear center B, but the extended portion 3 c does not necessarily extend to the rear center B.
