Description

  The present invention relates to a crotch garment.

  Conventionally, there are garments with a crotch such as girdle and shorts that can improve the posture of the wearer by making the pelvis and hip joints stable and can easily walk (for example, Patent Document 1). In such garments with crotch, the strong tightening force part, which has a stronger tightening force than the body part, holds the greater trochanter and supports the gluteus musculosa, thereby expanding the range of motion of the hip joint and enabling stable walking. Yes.

Japanese Patent No. 3870232

  By the way, we often have to make asymmetrical movements in our daily lives, and the pelvis often becomes unstable due to sitting and crossing legs. If such a condition persists, the balance of muscle activity is lost and the left and right sides of the body become uneven, resulting in fatigue, dullness, and stiffness of the body. And when such a state becomes a habit, the body is further distorted and it becomes a vicious circle.

  In the technique such as Patent Document 1 described above, although it is possible to improve the posture and the way of walking of the wearer, attention has not been paid to relieving the fatigue and dullness of the body due to the distortion of the body in this way. It was.

  In general, in order to improve body distortion, it is desirable to take a bath slowly to get tired enough or to do stretching exercises, but it takes time and effort, so it is necessary to maintain a normal life. However, it is desired to easily prevent fatigue and stiffness of the body.

  The present invention has been made to solve the above problems, and provides a crotch garment that can reduce body distortion and relieve fatigue simply by wearing and living as usual. The purpose is to do.

  In order to solve the above problems, a crotch garment according to the present invention is a crotch garment that covers at least a part of a lower body of a wearer, and has a stretchable main body part, a pubic part that covers the vicinity of the pubic bone, The upper edge is formed in a downward convex shape that extends diagonally upward and downward from the central lower end of the upper part of the pubic part, and has a stronger tightening force than the main part, and the pubic part and upper edge so that one end supports the abdominal muscles. Connected to the part, facing obliquely downward along the direction of the muscle fibers of the inner abdominal oblique muscle, covering the greater trochanter, while the other end extends to the back side of the main body part to support the greater gluteus muscle, The belt-shaped first weak tightening portion having a tightening force stronger than the tightening force of the main body portion is connected to the left and right portions at a position corresponding to any portion on the lumbar spine from the sacrum. The apex of the bulge of the buttocks along or near the muscle fiber direction A belt-shaped second weak tightening portion having a tightening force stronger than the tightening force of the main body portion, covering at least a portion reaching the vicinity of the greater trochanter, and covering the greater trochanter, And a strong tightening portion having a tightening force stronger than the tightening force of the tightening portion.

  In the garment with the crotch, in the worn state, the upper edge end portion generates a tightening force in the direction of the pubic portion along the extending direction of the upper edge end portion, and the first and second weak tightening portions are walking. Occasionally, a tightening force is generated along the longitudinal direction of the belt, and the strong tightening portion supports the greater trochanter, thereby preventing the human body and clothing from being displaced at the greater trochanter position when worn.

  According to such a crotch garment, the tightening force acts in the direction of the pubic bone when worn by the upper edge portion, so that the wearer's pelvis is tilted forward and held. Further, since the tightening force acts on the greater trochanter by the strong tightening portion, displacement of the human body and clothing at the greater trochanter position is prevented. As a result, it is possible to create a stable trunk axis by tilting the pelvis forward while preventing back and forth shaking of the pelvis.

  Furthermore, because the tightening force acts on the abdominal and gluteal muscles along the longitudinal direction of the band when walking, the weak tightening part provides good support for kickback following the movement of the pelvic band, and the position of the pelvis It can be pulled back to the center of the trunk. As a result, the movement of the pelvic belt can be induced with a good balance between left and right, and the muscles around the pelvic belt can be used with a good balance.

  In this way, the wearer's pelvis is held in a tilted state, creating a stable trunk axis and guiding the movement of the pelvic band with a good balance between left and right, and using the muscles around the pelvic band in a balanced manner As a result, it is possible to reduce body distortion and improve the left-right balance of the body. Then, the muscles around the pelvis become flexible, the range of motion of the hip joint is expanded, and the dullness and fatigue of the legs and hips are reduced. As described above, according to the present invention, it is possible to reduce the distortion of the body and relieve the dullness and fatigue of the legs and waist simply by wearing and living as usual.

  In addition, it is preferable that the upper edge end portion extends obliquely upward and downward from the central lower end portion to at least a position above or above the upper anterior iliac spine. Similarly, it is preferable that the upper edge end portion extends obliquely upward and leftward from the center lower end portion to at least a position below the outermost part of the iliac crest.

  In addition, it is preferable that the central lower end portion of the upper edge end portion is disposed below from an intermediate point between the upper anterior iliac spine and the pubic bone. Similarly, it is preferable that the central lower end portion of the upper edge end portion is disposed above the pubic bone.

  In addition, it is preferable that the wearing pressure of the pubic portion is maximized.

  With this configuration, it is possible to increase the tightening force in the direction of the pubic bone when worn, and the action of tilting the pelvis further forward is increased. As a result, it is possible to further prevent the pelvic belt from shaking back and forth and from side to side. Can be further inclined to further improve stability.

  Moreover, it is suitable to provide the cloth part connected above the upper edge end part and covering the waist line in the worn state. Thereby, since the covering range at the time of wear can be extended to a waist line, a feeling of wear and design nature can be improved.

  The above-described present invention is preferably applied to a crotch garment for women. On the other hand, when a wearer is a man, the adhesiveness of the pubic part to a wearer falls by a vulva part, and the effect | action of the tightening force to the pubic direction at the time of the wear mentioned above may reduce. In addition, the wearer may be pressed by the pubic part and feel pain in the pudendal part.

  Therefore, the above-mentioned pubic part has a vulva escape part at the position of the vulva part of the male wearer, and the pressure applied to the vulva part escape part may be smaller than the pressure applied to other parts of the pubic part.

  According to this configuration, even if the wearer is a male, the pressure applied to the other parts of the pubic part excluding the vulva escape part can be increased, and the tightening force in the pubic direction when worn is appropriately applied. be able to. Therefore, even if the wearer is a male, as described above, the pelvis can be tilted forward, and as a result, the pelvis can be tilted forward and a stable trunk axis can be prevented while preventing anteroposterior blurring of the pelvis. Can be made. Moreover, according to this structure, the press of the vulva part by the vulva escape part of a pubic part can be reduced, and the pain of the vulva part of a male wearer can be reduced.

  Even in the above-described garment with a crotch suitable for men, it is preferable that the pressure applied to the portion other than the vulva escape portion of the pubic portion is the largest. According to this configuration, even if the wearer is a male, as described above, the tightening force in the direction of the pubic bone can be increased at the time of wearing, and the action of further tilting the pelvis further increases. The pelvic belt can be further prevented from shaking back and forth and left and right, and the pelvis can be tilted forward to further improve the stability.

  Moreover, it is suitable for the above-mentioned clothing with a crotch suitable for men to be provided with a cloth portion that is connected to the upper edge end portion and covers the waist line in a worn state. Thereby, even if a wearer is a man, as above-mentioned, a wear feeling and designability can be improved.

  According to the garment with a crotch according to the present invention, it is possible to reduce body distortion and relieve fatigue simply by wearing it and living as usual.

[First Embodiment]

  FIG. 1 is a perspective view showing a women's shorts as an example of a crotch garment according to the first embodiment of the present invention from the front side, and FIG. 2 shows the shorts according to the first embodiment from the back side. FIG. FIG. 3 is a front view of the skeletal structure in the vicinity of the pelvis of the human body for explaining the arrangement of the components of the shorts of the first embodiment. The shorts 1 shown in FIGS. 1 and 2 includes a main body portion 10, a pubic portion 20, an upper edge portion 30, a weak tightening portion 40, and a strong tightening portion 50.

  The main body 10 is made of a stretchable fabric, and is configured to cover the crotch and the buttocks while having adhesion to the wearer. A warp knitting material (power net) made of nylon and polyurethane, for example, can be applied to the main body 10.

  The pubic portion 20 is formed in a portion corresponding to the vicinity of the wearer's pubic bone 71 (see FIG. 3). In the pubic portion 20, a material having a stronger tightening force than the main body portion 10 and a strong tightening portion 50 described later (for example, a warp knitted T / W material mixed with nylon and polyurethane) in order to suitably generate an action of tilting the pelvis forward ) Is particularly suitable, but it is also possible to apply the same material as the main body 10 or a non-stretchable material. The main body portion 10, the upper edge portion 30, the weak tightening portion 40, and the strong tightening portion 50) may be the largest. When the wearing pressure of the pubic part 20 is the highest, the pubic part 20 acts to push the vicinity of the pubic bone 71 into the inside of the body, and as a result, the action of tilting the pelvis forward increases.

  The upper edge portion 30 has, on the front side of the main body portion 10, centered on the central lower end portion 30a on the trunk, left and right end portions 30b and 30c on the upper side of the trunk 10 and the upper anterior iliac spine 72 (see FIG. 3). It is formed in a downward convex shape so as to cover. More specifically, the upper edge portion 30 has an arcuate curve that protrudes downward with the central lower end portion 30a as the lowest point in the front central region 10a of the main body portion 10. Then, while gradually transitioning to a curve that protrudes upward toward the side, it gradually approaches asymptotically parallel to the waistline, and on the rear side, parallel to the waistline as shown in FIG. It extends in the left-right direction. The central lower end portion 30a and the peripheral portion thereof are the upper edge ends of the pubic portion 20.

  The central lower end 30 a of the upper edge 30 is preferably arranged between the pubic bone 71 and the midpoint between the upper anterior iliac spine 72 and the pubic bone 71. That is, the lower limit position of the central lower end 30a of the upper edge 30 is preferably on the pubic bone 71, in other words, within a range of about 1 cm above and below the height position of the greater trochanter 73 (see FIG. 3). It is preferable. The upper limit position of the central lower end 30a of the upper edge 30 is an intermediate point between the upper anterior iliac spine 72 and the pubic bone 71, more specifically, the height position of the upper anterior iliac spine 72 and the pubic bone 71. It is preferable to be in a range of about 1 cm above and below the height position substantially in the middle of the height position (the height position of the greater trochanter 73).

  Further, the end portions 30b and 30c of the upper edge end portion 30 are preferably disposed between the upper anterior iliac spine 72 and the outermost portion 74 of the iliac crest. That is, the lower limit positions of the end portions 30b and 30c of the upper edge end portion 30 are on the upper anterior iliac spine 72, and the upper limit position is the height position of the outermost portion 74 of the iliac crest. And as for the upper edge end part 30, it is especially preferable that edge part 30b, 30c is arrange | positioned on the upper anterior iliac spine 72 at the time of wear. Here, the “outermost part of the iliac crest” refers to a part of the iliac crest that projects most in the left-right direction when the pelvis is viewed from the front as shown in FIG. 3.

  That is, the range that can be taken by the upper edge portion 30 in the present embodiment is a region 75 indicated by hatching in FIG.

  The upper edge portion 30 generates a tightening force in the direction of the pubic portion along the extending direction of the upper edge end portion. Specifically, the upper edge portion 30 can generate a tightening force F1 toward the pubic portion 20 as shown in FIG.

  The upper edge 30 is made of the same material as the main body 10 or a tape having a stronger tightening force than that of the main body 10 so that the tightening force is stronger than that of the main body 10. It is preferable to form a thin strip as shown in FIG. The tightening force of the upper edge portion 30 may be equal to or less than that of the weak tightening portion 40, may be equal to or less than that of the strong tightening portion 50, or the pubic portion. When a material having a tightening force stronger than that of the strong tightening portion 50 is used for 20, it may be equal to or less than the tightening force of the pubic portion 20.

  The weak tightening portion 40 is connected to the pubic portion 20 and the upper edge portion 30 so that one end 40c thereof supports the abdominal muscle, and the other end is formed to extend to the back side so as to support the greater gluteus muscle. The first tightening portion (first weak tightening portion) 40a and the second tightening portion (second weak tightening portion) 40b are configured. Here, in more detail, the abdominal muscles are mainly internal oblique muscles. One end 40 c of the first tightening portion 40 a is connected to the pubic portion 20 and the upper edge end portion 30. More specifically, one end 40c of the first tightening portion 40a extends from the upper part of the left and right ends of the pubic portion 20 to a portion of the upper edge end portion 30 adjacent to the intersection of the left and right ends of the pubic portion and the upper edge end portion 30. Are connected. Then, the first tightening portion 40a is obliquely downward along one of the one end 40c substantially along the muscle fiber direction of the internal oblique muscle, covering the greater trochanter 73, and along the lower edge of the main body portion 10 on the back side. And is formed in a band shape in which end portions from the left and right are connected at the center on the back side.

  The second tightening portion 40b is connected to the first tightening portion 40a so that one end thereof is in the vicinity of the greater trochanter 73 along the lower boundary line of the first tightening portion 40a. It extends obliquely upward toward the central waistline, and is formed in a belt shape so that the ends from the left and right are connected at the center on the back side. In other words, the left and right portions of the second tightening portion 40b are connected at a position corresponding to any portion on the lumbar vertebra from the sacrum, and the bulge of the buttock extends substantially along the muscle fiber direction of the left and right gluteus muscles from the position. Covers at least the part that passes through the apex of or near to the greater trochanter. Both the first tightening portion 40a and the second tightening portion 40b are formed symmetrically with respect to the axis of the wearer's trunk.

  The weak tightening portion 40 is configured to have a tightening force stronger than that of the main body portion 10, and is formed using, for example, an application cloth made of the same material as that of the main body portion 10. Specifically, in the wearing state, the first tightening portion 40a generates a tightening force F2 along the longitudinal direction between the one end 40c and the other end on the back side. The second tightening portion 40b is tightened along the longitudinal direction between the connecting portion with the first tightening portion 40a in the vicinity of the greater trochanter and the portion where the left and right end portions are connected at the center on the back side. A force F3 is generated.

  When the one end 40c of the first tightening portion 40a is coupled to the pubic portion 20, the position 40d of the intersection of the lower boundary line of the one end 40c of the first tightening portion 40a and the left and right ends of the pubic portion 20 is 71 is preferable, in other words, it is preferably in the range of about 1 cm above and below the height position of the greater trochanter 73. This is the same as the lower limit position of the central lower end portion 30a of the upper edge end portion 30 described above.

  The strong tightening portion 50 is formed so as to cover the greater trochanter 73 and is configured to have a tightening force stronger than that of the main body portion 10 and the weak tightening portion 40. Specifically, the strong tightening portion 50 is a portion where the first tightening portion 40a and the second tightening portion 40b overlap, and is a rhombus-shaped portion hatched in FIGS. In the case where the first tightening portion 40a and the second tightening portion 40b are formed using a patch, a double tightening force is used so that the tightening force is stronger than that of the main body 10 and the weak tightening portion 40. It is configured as follows.

  The strong tightening portion 50 supports the greater trochanter with a tightening force stronger than that of the weak tightening portion 40 as described above, thereby preventing the human body and the clothing from being displaced at the greater trochanter position when worn.

  The strong tightening portion 50 is a portion that covers the greater trochanter 73, and taking into account individual differences and movable regions, about 8-10 cm in the vertical direction about the position of the greater trochanter of a standard body shape, in the front-rear direction. It is preferable to cover an area of about 15 to 20 cm. Therefore, the lowest point of the strong tightening portion 50 is a standard body shape, and is preferably about 4 to 5 cm below the position of the greater trochanter 73.

  In the shorts 1 configured as described above, a tightening force F1 toward the pubic portion 20 is generated by the upper edge end portion 30 along the extending direction of the upper edge end portion 30 when worn. The tightening force F1 stabilizes the pelvis in a tilted state. As a result, a stable trunk axis can be created in the pelvic belt.

  Furthermore, since the pressure applied to the pubic portion 20 is maximized, the forward tilted state of the pelvis is further stabilized, and a more stable pelvic belt axis can be created.

  Further, since the strong tightening portion 50 covers the greater trochanter with a larger tightening force than the first tightening portion 40a, it is possible to prevent the human body and clothing from being displaced at the greater trochanter position when worn.

  By the way, the pelvis is originally in a state where it has fallen slightly forward when viewed from the side, but gradually becomes upright when an extra load is applied such as a strange way of walking in daily life. If the amount of pelvic anteversion is reduced, the trunk axis will not be stable and the balance of movement will be poor.

  According to the shorts 1 of the present embodiment, in consideration of such a state, by applying the tightening force F1 from the upper pelvis to the pubic bone 71, the wearer's pelvis is held in a forward tilted state and is stable. You will be able to create a trunk axis.

  Further, in the shorts 1 configured as described above, the longitudinal tightening forces F2 and F3 of the first tightening portion 40a and the second tightening portion 40b constituting the weak tightening portion 40 follow the movement of the pelvic belt during walking. Good kickback support can be provided, and the position of the pelvis can be pulled back to the center of the trunk. As a result, the movement of the pelvis can be induced in a balanced manner, and the muscles around the pelvic belt can be used in a balanced manner.

  As described above, according to the shorts 1 of the present embodiment, the wearer's pelvis is held in a forward tilted state, a stable trunk axis is formed, and the movement of the pelvic belt is guided with a good balance between the left and right sides. The muscles around the belt can be used in a balanced manner. As a result, the distortion of the body is reduced, the left / right balance of the body is improved, the muscles around the pelvis are flexible, the range of motion of the hip joint is expanded, and the dullness and fatigue of the legs and waist can be eased.

  FIG. 4 is a diagram illustrating improvement of the left-right balance of the body by the shorts 1 of the first embodiment. FIG. 4A and FIG. 4B are the same person and are measured at the same time although they are on different days. FIG. 4 (a) is a diagram showing the left-right difference in the range of motion of the hip joint when the measurement shorts are worn after wearing other shorts as a comparative example for 6 hours, and FIG. 4 (b) shows the present embodiment. It is a figure which shows the left-right difference of the internal rotation movable range of the hip joint at the time of wearing the measurement shorts after wearing the form shorts 1 for 6 hours. FIG. 4C is a diagram showing the difference in the left-right difference in the internal rotation range of the hip joint in FIGS. 4A and 4B. As shown in FIG.4 (c), by wearing the shorts 1 of this embodiment, it turns out that the left-right difference of the internal rotation angle of a hip joint is reduced, and the left-right balance of the body is improved.

The shorts 1 of the first embodiment described above is preferably applied to a crotch garment for women. On the other hand, when a wearer is a man, the adhesiveness of the pubic part 20 with respect to a wearer falls by a vulva part, and the effect | action of the tightening force F1 to the pubic direction at the time of wearing mentioned above may reduce. Moreover, a wearer may be pressed by the pubic part 20 by the pubic part 20 and may feel pain in the pudendal part. Therefore, the inventors of the present application devise a male underwear that can improve the above problems.
[Second Embodiment]

  FIG. 5 is a perspective view showing a male undergarment as an example of a crotch garment according to the second embodiment of the present invention from the front side, and FIG. 6 is a back view of the male undergarment according to the second embodiment. It is a figure shown from the side. A male undergarment 1A shown in FIGS. 5 and 6 is different from the first embodiment in that the female shorts 1 includes a main body portion 10A and a pubic portion 20A instead of the main body portion 10 and the pubic portion 20.

  The main body portion 10A is made of a stretchable fabric, like the main body portion 10 described above, and is configured to cover the crotch portion and the heel portion while having adhesion to the wearer. For the main body 10A, for example, a sheet material made of cotton and polyurethane is applicable.

  The pubic portion 20A is formed in a portion and a crotch portion corresponding to the vicinity of the wearer's pubic bone 71 (see FIG. 3). The pubic portion 20A has a vulva escape portion 20a at the position of the vulva of the male wearer, and the pressure applied to the vulva portion 20a is smaller than the pressure applied to the other portion 20b of the pubic portion 20a. In this way, the pubic part 20A is formed so as to suitably generate an action of tilting the pelvis forward by the other part 20b excluding the vulva escape part 20a.

  FIG. 7 is an exploded view of the pubic portion 20A in order to describe the pubic portion 20A in detail. As shown in FIG. 7, the pubic portion 20A includes a front fabric 20c, a back fabric 20d, and a built-in member 20e built between the front fabric 20c and the back fabric 20d. For example, the same material as that of the main body 10A may be applied to the front fabric 20c and the back fabric 20d.

  On the other hand, the built-in member 20e has a shape in which a portion corresponding to the male genital region (that is, the external genitalia, particularly the penis and the testicle) is cut out when worn. In the present embodiment, the built-in member 20e has a substantially inverted U-shaped pattern shape in order to form an oval cut shape. The built-in member 20e has a shape cut out in a gourd shape so that the cutout width is narrowed below the tip of the penis (the glans), and the left and right sides of the lower part of the gourd are sewn and elliptical. Make a hollow part. This cut-out portion corresponds to the vulva escape portion 20a of the pubic portion 20A.

  In the built-in member 20e, a material having a stronger tightening force than the main body 10A and the strong tightening portion 50 (for example, a warp knitted T / N mixed with nylon and polyurethane) is preferably used to cause the pelvis to tilt forward as described above. (W power net material) is particularly suitable, but it is also possible to apply the same material as the main body 10A or a non-stretchable material, and the portion 20b other than the vulva escape portion 20a of the pubic portion 20A. It is only necessary that the pressure of pressure increases as compared with the other parts (the main body portion 10A, the upper edge portion 30, the weak tightening portion 40, and the strong tightening portion 50). Since the pressure applied to the portion 20b other than the vulva escape portion 20a of the pubic portion 20A is the highest, the pubic portion 20A acts to push the vicinity of the pubic bone 71 into the inside of the body. As a result, the pelvis tilts forward. Becomes larger.

  Then, the male underwear 1A of the second embodiment is similar to the shorts 1 of the first embodiment in that the upper edge portion 30, the weak tightening portion 40 (the first tightening portion 40a and the second tightening portion 40b), And the strong tightening part 50 is provided.

  In the women's shorts 1 according to the first embodiment, on the front side, the upper edge end 30 forms a curve from the central lower end 30a upward to the side and gradually asymptotically becomes parallel to the waistline. As an example, a straight design is preferred for men's underwear. Accordingly, in the male undergarment 1A of the second embodiment, on the front side, the upper edge end portion 30 has a substantially V-shape extending substantially linearly from the central lower end portion 30a toward the upper side. May be.

  Moreover, in the shorts 1 for women of 1st Embodiment, the position of the center lower end part 30a of the upper edge part 30, the lower boundary line of the one end 40c of the 1st fastening part 40a, and the right and left ends of the pubic part 20 An example of the intersection position 40d is the lower limit position of the central lower end portion 30a of the upper edge end portion 30; however, in the male underwear, the lower end portion of the central portion of the upper edge end portion 30 so as not to hit the vulva The position of 30a is preferably close to the upper limit position of the central lower end 30a of the upper edge 30.

  According to the male underwear 1A of the second embodiment, even if the wearer is a male, the wearing pressure of the other part 20b excluding the vulva part escape part 20a of the pubic part 20A can be increased. The tightening force F1 in the pubic direction can be appropriately applied. Therefore, even if the wearer is a male, as described above, the pelvis can be tilted forward, and as a result, the pelvis can be tilted forward and a stable trunk axis can be prevented while preventing anteroposterior blurring of the pelvis. Can be made.

  Therefore, the same advantage as the shorts 1 of the first embodiment can be obtained even in the male underwear 1A of the second embodiment.

  In addition, according to the male underwear 1A of the second embodiment, pressing of the vulva by the vulva escape portion 20a of the pubic portion 20A can be reduced, and pain of the vulva of the male wearer can be reduced. it can.

  As described above, the crotch garment according to the present invention has been described by taking the preferred embodiment by taking the women's shorts 1 and the male underwear 1A as an example, but the present invention is not limited to the above embodiment. For example, as shown in FIG. 8, the shorts 1 may be configured to include a cloth portion 60 that covers the waist line further above the upper edge portion 30. Similarly, as shown in FIG. 9, the male undergarment 1 </ b> A may be configured to include a cloth portion 60 that covers the waistline further above the upper edge portion 30. A material similar to that of the main body portions 10 and 10A can be applied to the cloth portion 60. Thereby, since the covering range at the time of wear can be extended to a waist line, the wearing feeling and design nature of shorts 1 or men's underwear 1A can be improved.

  In addition, the material of the main body 10, 10A is not limited to this embodiment, and women such as warp knitting materials such as power nets and laces, weft knitting materials such as tengu, and circular knitting (molding knitting) materials Various materials used as materials for shorts for men and underwear for men are applicable.

  Moreover, the attachment method to the main-body part 10 of the weak tightening part 40, the strong tightening part 50, and the pubic part 20 may be sewn, or may be affixed. Further, the weak tightening portion 40, the strong tightening portion 50, and the pubic portion 20 may be formed in contact with the main body portion 10, or may be changed into a knitting method to be a portion having a strong tightening force. Further, the weak tightening portion 40, the strong tightening portion 50, and the pubic portion 20 may be formed integrally with the main body portion 10 by applying urethane resin (printing or the like) or performing opal processing.

  In the second embodiment, the three-layer structure in which the visceral member 20e is incorporated between the front fabric 20c and the back fabric 20d is exemplified as a method for forming the pubic portion 20A. However, the pubic portion 20A is also described above. Similarly to the forming method 20, the member 20e may be sewn, pasted, or joined to the main body 10A. Further, the pubic portion 20A may be formed by changing the knitting method when forming the main body portion 10A in the same manner as the method for forming the pubic portion 20, or by applying urethane resin (printing or the like). Alternatively, it may be formed by opal processing.

  Further, the upper edge portion 30 is formed by sewing or attaching a tape or a stretch lace to the main body portion 10 (main body portion 10A), turning back, connecting the lower abdomen clothing and the main body portion 10 (main body portion 10A), or the like. May be formed so as to have a stronger tightening force than the main body 10 (main body 10A), or by changing the knitting method, applying urethane printing (printing, etc.), opal processing, etc. You may form so that it may become stronger tightening force than the main-body part 10 (main-body part 10A), forming integrally with the part 10 (main-body part 10A).

  Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to the following examples. In addition, the description same as the shorts 1 for women and the underwear 1A for men of the said embodiment is abbreviate | omitted.

  First, the function verification test was implemented about the shorts 101,102,103 which concerns on Examples 1-3 of the 1st Embodiment of this invention, and the shorts 104,105,106,107 which concerns on Comparative Examples 1-4. FIG. 10 is a perspective view showing the shorts according to the example of the first embodiment of the present invention and the shorts according to the comparative example from the front side.

  In Example 1 shown in FIG. 10 (a), the central lower end 31a is located approximately in the middle of the upper anterior iliac spine 72 and the pubic bone 71 (the above-mentioned upper limit position), and the upper left and right sides are centered on this central lower end 31a. The shorts 101 includes an upper edge end portion 31 formed in a downward convex shape passing over the anterior iliac spine 72 and a pubic portion 21 to which the same material as the main body portion 10 is applied. In Example 2 shown in FIG. 10 (b), the central lower end 32a is located on the pubic bone 71 (the above-mentioned lower limit position), and the lower part passes over the left and right upper anterior iliac spines 72 around the central lower end 32a. The shorts 102 includes a convex upper edge portion 32 and a pubic portion 22 having a higher pressure than the main body portion 10 and the strong tightening portion 50. In Example 3 shown in FIG. 10 (c), the central lower end 31a is located approximately in the middle of the upper anterior iliac spine 72 and the pubic bone 71 (the above-mentioned upper limit position), and the upper left and right sides are centered on this central lower end 31a. The upper edge portion 31 formed in a downward convex shape passing over the anterior iliac spine 72 (that is, having the same shape as that of the first embodiment), and the pubic portion 23 having higher pressure than the main body portion 10 and the strong tightening portion 50. The shorts 103 is provided.

  In Comparative Example 1 shown in FIG. 10 (d), the pubic bone is such that the central lower end 33 a of the upper edge end 33 is above the above upper limit position, is located below the waistline, and is higher in pressure than the strong tightening portion 50. This is a shorts 104 including a section 24. Comparative example 2 shown in FIG. 10 (e) is a shorts 105 having a pubic portion 25 in which the central lower end portion 34 a of the upper edge end portion 34 is located on the waist line and the pressure is higher than that of the strong tightening portion 50. In Comparative Example 3 shown in FIG. 10 (f), the central lower end 31 a of the upper edge end 31 is substantially in the middle of the upper anterior iliac spine 72 and the pubic bone 71 (ie, the upper limit position described above) (that is, the first and third embodiments). (Similarly) with the pubic portion 23 positioned and having higher pressure than the strong tightening portion 50 (having the same shape and function as in the third embodiment), and the shorts 106 without the weak tightening portion 40 and the strong tightening portion 50 is there. The comparative example 4 shown in FIG. 10 (g) does not include the upper edge portion 30, the weak tightening portion 40, and the strong tightening portion 50, and further uses the same material as that of the main body portion 10 without using a patch on the pubic portion 26. It is the shorts 107 which applies.

  And the functional verification test was implemented about shorts 101,102,103 which concerns on Examples 1-3 of this invention, and shorts 104,105,106,107 which concerns on Comparative Examples 1-4. As a measuring device, a functional verification test for measuring the posture of a shorts wearer during walking was performed using an optical reflection type motion capture system manufactured by VICON. In this functional verification test, the wearer of the shorts walked at a speed of 3.8 km per hour, the measurement was started after the wearer walked for 90 seconds, and the measurement was terminated after the walk for 12 seconds.

  In the functional verification test, a marker detected by a measuring device is attached to each of the sternum, xiphoid process, seventh cervical vertebra, and tenth thoracic vertebra to form a segmental segment, left anterior iliac spine, right anterior iliac spine, Markers were attached in the vicinity of the left posterior iliac spine and the right posterior iliac spine to form a pelvic segment.

  Then, based on the relative relationship between the segment segment and the pelvic segment, the range of rotation (difference) and the difference (the rotation angle to the left from the reference position) And the difference between the rotation angle in the right direction from the reference position), the range of lateral bending of the wearer, and the difference in right and left, respectively, the movable range and the difference in right and left were calculated. The left / right difference is the ratio (%) of the left / right difference to the movable range. A larger rotation range indicates a correct walking posture, and the closer the rotation difference between left and right, the range of lateral bending, and the left and right difference are to 0, the more correct walking posture is. The “segment” is an operation unit based on the positions of the four points to which the markers are attached. For example, based on the correlation between the midpoints of the four points to which the markers are attached, The difference, the range of lateral bending, and the left / right difference may be calculated.

  Here, in the case of a wearer with a distorted skeleton, the state of leaning to the left or right during walking can be regarded as standard, so if the range (amplitude) of the side bending action is reduced, the distortion is reduced. Can be evaluated.

  In the function verification test, for the five wearers A to E, comparison was made between the case where the shorts according to the present invention (Examples 1 to 3) were worn and the case where the comparative examples 1 to 4 were worn.

  FIG. 11 is a diagram illustrating a result of the function verification test. In FIG. 11, each of the measurement results of Examples 1 to 3 and Comparative Examples 1 to 3 is improved from that of Comparative Example 4 (that is, the range of rotation is increased, the lateral difference of rotation, the range of lateral bending) And the left-right difference is small). And about each of Examples 1-3 and Comparative Examples 1-3, the number of wearers AE where the measurement result was improved as compared with Comparative Example 4 is shown in the “Number of people count” column.

  In Examples 1 to 3, both the range of rotation and the left-right difference are improved compared to the comparative example, and the effect of improving the left-right difference of the rotation is particularly great. Further, when attention is paid to the left-right difference and the movable range of the rotation in Examples 1 to 3, it can be seen that Example 2 is most improved.

  Moreover, in Example 1, since the tightening force of the pubic portion 21 itself is small and the force (fixed pressure) is concentrated on the pubic bone by the upper edge portion 31, it is considered that the left-right difference in rotation is small. In Example 2, since the contact pressure of the pubic portion 22 is increased, it is considered that the range of rotation of rotation is increased. In Example 3, since the area of the pubic portion 23 is larger than that in Example 2 and the contact pressure is dispersed, the evaluation of the movable range of rotation is lowered. However, in Example 1, the pubic part 21 is the same material as the main body part 10 and does not use an application cloth. In Example 2, since the area of the pubic part 20 is small, both pubic hairs are visible, which is preferable in terms of design. Therefore, the function and design can be balanced by providing the pubic portion 23 up to the position of the third embodiment and making it difficult to see the vicinity of the pubic portion using a batter.

  As shown in FIG. 11, in Examples 1 to 3, since the left-right difference in rotation was improved, it was confirmed that body distortion was reduced and the left-right balance of the body was improved. Further, in Examples 1 to 3, the rotational range of motion was also improved, indicating that the body's distortion was reduced and the hip range of motion was widened.

  That is, according to the crotch garment according to the first embodiment of the present invention, it was confirmed that just wearing and living as usual can reduce body distortion and relieve fatigue.

  Next, a function verification test was performed on the male undergarments according to Examples 11 and 12 and the male undergarments according to Comparative Examples 11 to 13 of the second embodiment of the present invention.

  Example 11 is a male undergarment 1A of the second embodiment shown in FIGS. 5 and 6 and includes a main body portion 10A, a pubic portion 20A, an upper edge portion 30, a weak tightening portion 40 (first tightening portion 40a). And a second tightening portion 40b) and a strong tightening portion 50. That is, in Example 11, the pubic portion 20A has a vulva escape portion 20a with low pressure at the position of the vulva of the male wearer, and the pressure of the portion 20b other than the vulva escape portion 20a It is higher than 10A and strong tightening part 50. Further, in the eleventh embodiment, like the female shorts 103 of the third embodiment shown in FIG. 10C, the central lower end 30 a of the upper edge 30 is substantially in the middle of the upper anterior iliac spine 72 and the pubic bone 71 ( The upper edge portion 30 is formed in a downward convex shape that is located at the above-described upper limit position and passes on the left and right upper anterior iliac spines 72 with the central lower end portion 30a as the center.

  Example 12 differs from Example 11 in the upper edge end 30. That is, in Example 12, like the female shorts 102 of Example 2 shown in FIG. 10B, the central lower end 30a of the upper edge end 30 is located on the pubic bone 71 (the above-mentioned lower limit position), The upper edge portion 30 is formed in a downward convex shape passing through the left and right upper anterior iliac spines 72 around the central lower end portion 30a.

  The comparative example 11 differs in the pubic part 20A in Example 11. That is, in Comparative Example 11, the pubic part 20A does not have the vulva escape part 20a, and the entire pubic part 20A has a higher pressure than the main body part 10A and the strong tightening part 50.

  The comparative example 12 differs in the upper edge part 30 in Example 11. FIG. That is, in the comparative example 12, like the female shorts 104 of the comparative example 1 shown in FIG. 10D, the central lower end 30a of the upper edge end 30 is above the above upper limit position and below the waistline. Located in.

  The comparative example 13 is similar to the female shorts 107 of the comparative example 4 shown in FIG. 10 (g). In the comparative example 13, the upper edge portion 30, the weak tightening portion 40 (the first tightening portion 40a and the second tightening portion) are used. 40b) and the strong tightening portion 50 is not provided, the pubic portion 20A does not have the vulva escape portion 20a, and the same material as the main body portion 10 is applied to the entire pubic portion 20A.

  In this functional verification test, the left and right difference in the wearer's foot pressure was measured after the wearer spent about 6 hours wearing everyday life. And in this functional verification test, about five wearers FJ, the case where the underwear for men concerning the present invention (Examples 11 and 12) is worn, and the case where comparative examples 11-13 are worn. Was done.

  FIG. 12 is a diagram showing the results of this function verification test. In FIG. 12, each of the measurement results of Examples 11 and 12 and Comparative Examples 11 and 12 is marked with a circle when it is improved from that of Comparative Example 13 (that is, the foot pressure left-right difference is reduced). . For each of Examples 11 and 12 and Comparative Examples 11 and 12, the number of wearers FJ whose measurement results are improved as compared with Comparative Example 13 is shown in the “Number of people count” column.

  In this functional verification test, when there are three or more wearers who have an improvement effect, it is evaluated that there is an improvement effect.

  As can be seen from FIG. 12, the foot pressure left-right difference is improved in Example 11 and Comparative Example 11 compared to Comparative Example 13. In particular, in Example 11, it can be seen that the foot pressure left-right difference is most improved. In the following, these results will be verified.

  In Comparative Example 11, since the pubic part 20A does not have the vulva escape part 20a, the pressure applied to the wearer by the pubic part is reduced by the vulva part, and the above-described action of the tightening force F1 in the pubic direction at the time of wearing is described above. Is considered to have been reduced. On the other hand, in Example 11, it was possible to increase the pressure applied to the other portion 20b of the pubic portion 20A excluding the vulva escape portion 20a, and to appropriately apply the tightening force F1 in the pubic direction when worn. It is considered a thing.

  Moreover, in the comparative example 12, since the center lower end part 30a of the upper edge part 30 is higher than the above-mentioned upper limit position, the effect | action of the tightening force F1 to the pubic direction at the time of the wear reduces, and the pelvis is inclined forward. It is thought that a stable trunk axis could not be made. On the other hand, in Example 11, the central lower end 30a of the upper edge 30 is located at the above-mentioned upper limit position, so that the tightening force F1 in the pubic direction when worn can be appropriately applied, and the pelvis is tilted forward It is thought that we were able to create a stable trunk axis.

  Here, as described above, in the case of women's shorts, the improvement effect was greater as the central lower end portion 30a of the upper edge end portion 30a was closer to the lower limit position. The improvement effect of Example 11 in which the central lower end 30a of the upper edge end 30 is the upper limit position was greater than that of Example 12 in which the central lower end 30a of the upper edge end 30 was the lower limit position. In the twelfth embodiment, because the central lower end 30a of the upper edge end 30 is low in the twelfth embodiment, depending on the person, the central lower end 30a of the upper edge end 30 hits the vulva and the center of the upper edge end 30 relative to the wearer It is considered that the adhesiveness of the lower end 30a is lowered by the vulva part, and the action of the tightening force F1 in the pubic direction at the time of wearing described above may be reduced. In other words, in the case of male underwear, it is considered preferable that the central lower end 30a of the upper edge end 30 is located at the upper limit position.

  Thus, since the left-right difference in foot pressure was improved in Example 11, it was confirmed that even when the wearer was a male, the body distortion was reduced and the left-right balance of the body was improved. Further, in Example 11, the range of motion of the rotation was also improved, indicating that the body's distortion was reduced and the range of motion of the hip joint was expanded.

  That is, according to the garment with a crotch according to the second embodiment of the present invention, even if the wearer is a man, it is possible to reduce the distortion of the body just by wearing and living as usual, and fatigue. We can expect to be able to relieve.

  It can be applied to applications that can reduce body distortion and relieve fatigue simply by wearing it and living as usual.
