Description

underwear

The present invention relates to an inner wear, and more particularly, to an underwear capable of guiding a pelvis to a correct inclination.

A corset is known as the most common device for treating low back pain while fixing the pelvis and protecting the waist. Tight vests can be used for emergency measures and have the advantages of fast-acting and easy to put on and take off. On the other hand, the tight waistcoat may swell from the correct wearing position, thereby reducing the effect. In addition, tight vests may reduce muscle strength due to long-term use, and the wearer may have a vicious cycle that requires more and more tight vests to be worn. Also, a lower body shirt for pelvic correction like Patent Document 1 is also known. [Prior Art Literature] [Patent Literature]

[Problems to be Solved by the Invention]

However, if the balance of muscle strength around the pelvis is poor, the pelvis will lean forward or backward. FIG. 1A is a side view of a schematic pelvis near a person with a pelvis in a correct position, and FIG. 1B is a side view of a schematic pelvis near a person with a bent waist. M1 is the back muscle, M2 is the abdominal muscle, M3 is the iliopsoas, and M4 is the posterior leg tendon. In these figures, the pelvis is shown schematically as a triangle. Generally speaking, it is more common in women. If the muscles around the pelvis, such as the abdominal muscle M2, the iliopsoas M3, and the hamstring M4 on the back of the thigh, are weak, and the back muscle M1 is strong, as shown in Figure 1B Shows that the pelvis will lean forward. Also, although not specifically shown, if the balance of muscle strength around the pelvis is poor, the pelvis may tilt back. The forward and backward tilt of the pelvis can also cause low back pain, so its countermeasures are important. However, if only the pelvis is only protected around the tight vest, the effect is not good. Furthermore, the shirt for the lower body of Patent Document 1 is not sufficient to correct the forward and backward tilt of the pelvis.

The present invention provides an undergarment capable of guiding a pelvis to a correct inclination. [Means for solving problems]

<2. Configuration of Each Part> Hereinafter, various fabrics 1, fabric 20, fabric 30, fabric 40, fabric 50, fabric 60, fabric 70, and fabric 80 constituting the underwear 100 will be described.

<2-1. Base fabric> Base fabric 1 is composed of three types of fabric 11, fabric 12, and fabric 13. The cloth 11 includes a right body portion 11R mainly covering a right hip, a right lower abdomen, and a right thigh, and a left body portion 11L mainly covering a left hip, a left lower abdomen, and a left thigh. The cloth 11R and the cloth 11L have left-right symmetrical shapes.

The cloth 12 is a cloth covering the vicinity of the left and right centers of the lower abdomen, and has a substantially inverted trapezoid shape. The left and right edges 12L and 12R corresponding to the bottom of the trapezoidal shape of the cloth 12 are sewn to the upper portions of the front side edges of the left and right body portions 11L and 11R, respectively. The cloth 13 is a cloth covering the crotch portion and has a substantially rectangular shape. The edge corresponding to one side of the fabric 13 is stitched with the edge 12D corresponding to the bottom edge of the fabric 12. Further, the edges corresponding to the other two sides of the cloth 13 are below the cloth 12 and are sewn to the upper and lower central portions of the front side edges of the left body portion 11L and the right body portion 11R, respectively. Moreover, the upper part of the edge of the back side of the left body part 11L and the right body part 11R is sewn to each other. Thereby, a tubular portion covering the buttocks and the lower abdomen is formed.

The lower part of the front side edge and the lower part of the back side edge of the right body portion 11R are sewn. As a result, the right foot of the wearer passes through and covers the tubular portion of the right thigh. Similarly, the lower part of the front side edge of the left body part 11L and the lower part of the back side edge are sewn together. As a result, the wearer's left foot passes through and covers the tubular portion of the left thigh. Further, the edge corresponding to the remaining side of the cloth 13 is sewn to the upper and lower central portions of the edges on the back side of the left and right body portions 11L and 11R.

As described above, if all four pieces of cloths of the right body portion 11R and the left body portion 11L, and the cloth material 12 and the cloth material 13 are connected, the base cloth 1 having a corset shape is formed. Furthermore, in this embodiment, all of the four cloths 11R, 11L, 12 and 13 constituting the base cloth 1 contain the same raw materials, and are rich in elasticity in the vertical and horizontal directions. As a result, when the wearer wears underwear 100, the base fabric 1 is configured to closely fit the wearer's buttocks, lower abdomen, and thighs with a moderate pressure.

<2-2. Fabric for lower abdomen> The fabric 20 is a fabric covering the vicinity of the left and right centers of the lower abdomen and has a double-layer structure. 3A and 3B show two cloths 20A and 20B constituting the cloth 20 having a double structure, respectively. Hereinafter, these cloths 20A and 20B are referred to as lower abdomen cloths. The lower abdomen cloth 20A and the lower abdomen cloth 20B have substantially the same shape as the cloth 12 included in the base cloth 1 and covering the vicinity of the left and right centers of the lower abdomen, and have a substantially inverted trapezoid shape. The lower abdomen cloth 20A, the lower abdomen cloth 20B, and the cloth 12 are recombined into a three-layer structure, and the outer circumferences of the three pieces of cloth 20A, the cloth 20B, and the cloth 12 are sewn to each other. More specifically, the lower abdomen cloth 20B and the inner side (wearer side) of the cloth 12 are overlapped, and the lower abdomen cloth 20A and the inner side (wearer side) of the lower abdomen cloth 20B are overlapped. That is, the lower abdomen cloth 20B is a middle cloth enclosed between the cloth 12 and the lower abdomen cloth 20A. The lower abdomen cloth 20A and the lower abdomen cloth 20B are sewn on the inner side of the undergarment 100, so the appearance is not affected.

In this embodiment, the two lower abdominal fabrics 20A and the lower abdominal fabrics 20B each include a raw material having higher elasticity than the base fabric 1 in the vertical and horizontal directions, and further includes the same raw materials. However, the stretchability of these lower abdominal fabrics 20A and 20B is different. To explain more specifically, in FIG. 3A and FIG. 3B, arrows extending in the up-down direction and the left-right direction are shown, respectively, and these arrows indicate directions in which the modulus of elasticity is the lowest. As shown in these FIGS. 3A and 3B, in this embodiment, the lower abdomen cloth 20A and the lower abdomen cloth 20B are aligned so that the most stretchable directions are orthogonal to each other. In this embodiment, the lower abdomen cloth 20A is most easily stretchable in the up-down direction, and the lower abdomen cloth 20B is most easily stretchable in the left-right direction. However, the orientation in the telescopic direction may be reversed. In addition, in FIG. 2C and FIG. 2D, the same arrows as those in FIG. 3A and FIG. 3B are also shown, and these arrows also indicate directions in which the elastic modulus is the lowest.

As a result, the lower abdominal fabric 20A and the lower abdominal fabric 20B are configured to closely fit the lower abdomen of the wearer with a stronger pressing force than the base fabric 1 when the wearer wears the underwear 100. Therefore, the lower abdomen cloth 20A and the lower abdomen cloth 20B can apply a compressive force to the abdomen muscle M2 of the wearer wearing the underwear 100 to tighten the abdomen muscle and its surroundings. 1A and 1B show the position of the abdominal muscle M2. As known from these FIGS. 1A and 1B, the tightening of the lower abdomen cloth 20A and the lower abdomen cloth 20B on the abdominal muscle M2 can bring, for example, an effect of pulling the front side of the forward-inclined pelvis of a person with a bent waist upward.

<2-3. Crotch cloth> The cloth 30 is a cloth covering the crotch. Hereinafter, the cloth 30 is referred to as a crotch cloth. The crotch cloth 30 has substantially the same shape as the crotch-covered cloth 13 included in the base cloth 1, and has a substantially rectangular shape. The crotch cloth 30 and the cloth 13 are recombined into a double-layer structure, and the outer periphery of the two cloths 30 and 13 are sewn to each other. More specifically, the crotch cloth 30 overlaps the inside (wearer side) of the cloth 13. Therefore, the crotch cloth 30 is sewn on the inner side of the underwear 100, and thus does not affect the appearance.

<2-4. Gum tape> The cloth 40 is an elongated rubber tape (hereinafter, the rubber tape is also referred to by the symbol 40), and is extended at the uppermost portion of the base cloth 1 so as to surround the waist. The rubber band 40 and the uppermost part of the base fabric 1 are recombined with each other into a double-layer structure, and both ends (upper and lower ends) in the short-side direction of the rubber band 40 are sewn along the long-side direction, respectively. In addition, both ends in the long side direction are also sewn along the short side direction. The rubber band 40 overlaps the inner side (wearer side) of the base fabric 1. Therefore, the rubber band 40 is sewn on the inner side of the underwear 100, and thus does not affect the appearance.

In this embodiment, the rubber band 40 includes a raw material having higher elasticity than the base fabric 1 in the vertical direction and the left-right direction. In this embodiment, the rubber band 40 is most easily expanded and contracted in the longitudinal direction (left-right direction). Therefore, when the wearer puts on and off the underwear, a portion around the waist of the underwear 100 can easily pass over the raised portion of the buttocks and the like, thereby making it easy to put on and take off. In addition, when the wearer wears the underwear 100, the rubber band 40 adheres tightly around the waist of the wearer with a stronger pressing force than the base fabric 1, so that the underwear 100 can be prevented from shifting when worn.

<2-5. Pelvic cloth> The cloth 50 is a cloth containing mesh gum that covers the pelvis in a band shape. Hereinafter, the cloth 50 is referred to as a pelvic cloth. The pelvic cloth 50 includes cloth 50L and cloth 50R, and the cloth 50L and cloth 50R have left-right symmetrical shapes. The cloth 50L is a cloth mainly covering the left side of the pelvis, the cloth 50R is a cloth mainly covering the right side of the pelvis, and the cloth 50L and the cloth 50R are two groups, covering about a circle around the pelvis. The pelvic cloth 50L and the pelvic cloth 50R and the left body portion 11L and the right body portion 11R included in the base cloth 1 respectively cover the surrounding part of the pelvis to form a double-layer structure. Both ends (upper and lower ends) in the short-side direction are sewn along the long-side direction, respectively. In addition, both ends in the long side direction are also sewn in the short side direction. The pelvic cloth 50L and the pelvic cloth 50R overlap the outside of the base cloth 1.

In this embodiment, the pelvic cloth 50L and the pelvic cloth 50R include raw materials having higher elasticity than the base cloth 1 in the up-down direction and the left-right direction, and further include the same raw materials. In this embodiment, the pelvic cloth 50L and the pelvic cloth 50R are most easily stretchable in the longitudinal direction (left-right direction). Therefore, when the wearer puts on and off the underwear, a portion around the waist of the underwear 100 can easily pass over the raised portion of the buttocks and the like, thereby making it easy to put on and take off.

In addition, the above result is that the pelvic cloth 50L and the pelvic cloth 50R are configured to closely fit around the pelvis of the wearer with a stronger pressing force than the base cloth 1 when the wearer wears the underwear 100. Therefore, the underwear 100 can be prevented from being shifted when worn. In addition, since the pelvic cloth 50R and the pelvic cloth 50L apply a fastening force to the pelvis of the wearer of the underwear 100, the pelvis can be supported in a tight manner.

<2-6. Fabric for lumbo-sacral muscle> The fabric 60 is an elongated cloth covering the area near the lumbo-muscle M3 or the base of the thigh. Hereinafter, the cloth 60 is referred to as a lumbosacral cloth. The cloth 60 includes cloth 60L and cloth 60R, and the cloth 60L and cloth 60R have left-right symmetrical shapes. The cloth 60L is a cloth mainly covering the left side near the lumbo-sacral muscle M3 or the base of the thigh, and the cloth 60R is a cloth mainly covering the right side near the lumbo-muscles M3 or the base of the thigh. The iliopsoas muscle cloth 60L and iliocismus cloth 60R and the left body portion 11L and the right body portion 11R included in the base cloth 1 respectively cover the areas around the lumbomuscle M3 or the base of the thigh to form a double-layer structure On the other hand, both ends in the short-side direction of the lumbo-sacral cloth 60L and 60R are stitched along the long-side direction, respectively. In addition, both ends in the long side direction are also sewn along the short side direction. Because of the above, the iliopsoas muscle cloth 60L and the iliopsoas muscle cloth 60R are sutured so that their long sides extend along the roots of the left and right thighs, respectively. More precisely, in this embodiment, the iliopsoas muscle cloth 60 extends substantially parallel to the line of the base of the thigh at a position several centimeters away from the line. The iliopsoas muscle cloth 60L and the iliocis muscle cloth 60R overlap the inner side (wearer side) of the base cloth 1. Therefore, the iliopsoas muscle cloth 60L and the iliocis muscle cloth 60R are sewn on the inner side of the underwear 100, and therefore the appearance is not affected.

In this embodiment, the lumbo-sacral cloth 60L and the lumbo-sacral cloth 60R include raw materials having higher elasticity than the base cloth 1 in the vertical and horizontal directions, and further include the same raw materials. Therefore, when the wearer wears the undergarment 100, the wearer is configured to closely adhere to the portion of the wearer's thigh near the root of the thigh and the portion extending substantially parallel to the base of the thigh with a stronger pressing force than the base fabric 1. As a result, the iliopsoas muscle cloth 60L and the iliopsoas muscle cloth 60R can act near the base of the thigh of the wearer of the underwear 100 to assist the force for stretching in the direction of the muscle fiber to the lumbomuscle M3 existing in the body. Tighten the sacroiliac muscle M3 and its surroundings. 1A and 1B show the position of the iliopsoas muscle M3. As known from these FIGS. 1A and 1B, the tightening of the iliopsoas muscle cloth 60L and the iliopsoas muscle cloth 60R on the lumbomuscle M3 can bring, for example, the front side of the forward-inclined pelvis of a person who pulls the waist upward. effect.

Moreover, in this embodiment, as shown in FIG. 2C, the iliopsoas muscle cloth 60L and the iliopsoas muscle cloth 60R are most easily stretchable in the longitudinal direction, and the elastic modulus in the longitudinal direction of the line along the base of the thigh is less than The elasticity in the short-side direction orthogonal to the line at the root of the thigh makes it difficult to stretch in the short-side direction. However, it is also possible to make the lumbo-sacral cloth 60L and 60R the most easily stretchable in the short-side direction. The elasticity in the short-side direction is smaller than the elasticity in the long-side direction, making it difficult in the long-side direction. Telescopic composition. In all cases, the iliopsoas muscle cloth 60L and the iliopsoas muscle cloth 60R can follow the line of the root of the thigh, that is, approximately along the direction in which the lumbo-muscle muscle M3 extends, to make a powerful assisting force for stretching in the direction of muscle fibers Acts on the iliopsoas M3.

<2-7. Lifting cloth> The cloth 70 is a slightly elongated cloth that covers the lower part of the buttocks by lifting the buttocks. Hereinafter, the cloth 70 is referred to as a lift cloth. The cloth 70 includes cloth 70L and cloth 70R, and the cloth 70L and cloth 70R have left-right symmetrical shapes. The cloth 70L is a cloth mainly covering the lower part of the left side of the buttocks, and the cloth 70R is a cloth mainly covering the lower part of the right side of the buttocks. The lifting fabric 70L and the lifting fabric 70R are respectively overlapped with the parts covering the lower part of the buttocks of the left body part 11L and the right body part 11R included in the base fabric 1 to form a double-layer structure. Both ends in the short side direction of the 70R are sewn along the long side direction. In addition, both ends in the long side direction are also sewn along the short side direction. Because of the above, the lifting fabric 70L and the lifting fabric 70R are sewn in such a manner that the longitudinal direction thereof extends along the lower part of the buttocks. The lifting fabric 70L and the lifting fabric 70R overlap with the inner side (wearer side) of the base fabric 1. Therefore, the lifting fabric 70L and the lifting fabric 70R are sewn on the inner side of the undergarment 100, so the appearance is not affected.

In this embodiment, the lifting cloth 70L and the lifting cloth 70R include raw materials having higher elasticity than the base cloth 1 in the vertical and horizontal directions, and further include the same raw materials as each other. Therefore, when the wearer wears the underwear 100, the wearer is configured to closely fit the lower part of the wearer's buttocks with a stronger pressing force than the base cloth 1. As a result, the lifting fabric 70L and the lifting fabric 70R support the buttocks such that a force for lifting the lower part of the buttocks of the wearer wearing the underwear 100 is applied to the lower part of the buttocks, and the lifted part is fixed.

In addition, in this embodiment, the lifting cloth 70L and the lifting cloth 70R are most easily extended and contracted in the short-side direction (substantially the vertical direction). That is, the elastic modulus in the long-side direction (approximately the left-right direction) is larger than the elastic modulus in the short-side direction, and it is difficult to stretch. As a result, the lifting cloth 70L and the lifting cloth 70R can apply a strong pressing force to the lower part of the buttocks in the left-right direction, thereby lifting the lower part of the buttocks.

<2-8. Back leg tendon cloth> The cloth 80 is a slightly slender cloth covering the back leg tendon M4 or the back side of the thigh. Hereinafter, the cloth 80 is referred to as a posterior tendon cloth. The cloth 80 includes cloth 80L and cloth 80R, and the cloth 80L and cloth 80R have left-right symmetrical shapes. The cloth 80L is a cloth mainly covering the posterior tendon M4 of the left foot or the back side of the thigh, and the cloth 80R is a cloth mainly covering the posterior tendon M4 of the right foot or the back side of the thigh. The back leg tendon cloth 80L and the back leg tendon cloth 80R and the left body portion 11L and the right body portion 11R included in the base fabric 1 respectively cover the back leg tendon M4 or the back of the thigh to form a double layer structure On the other hand, the two ends of the posterior tendon cloth 80L and the posterior tendon cloth 80R in the short-side direction are sewn along the long-side direction, respectively. The hind-leg tendon cloth 80L and the hind-leg tendon cloth 80R coincide with the inner side (wearer side) of the base cloth 1. Therefore, the posterior leg tendon cloth 80L and the posterior leg tendon cloth 80R are sewn on the inner side of the underwear 100, and thus the appearance is not affected.

In this embodiment, the posterior leg tendon cloth 80L and the posterior leg tendon cloth 80R include raw materials having higher elasticity than the base cloth 1 in the up-down direction and the left-right direction, and further include the same raw materials as each other. Therefore, the back leg tendon cloth 80L and the back leg tendon cloth 80R are configured to closely adhere to the back side of the wearer's thigh with a stronger pressing force than the base fabric 1 when the wearer wears the underwear 100. As a result, the hind-leg tendon cloth 80L and the hind-leg tendon cloth 80R can apply a force assisting the expansion and contraction in the direction of muscle fibers to the posterior tendon M4 existing inside the body on the back of the thigh of the wearer wearing underwear 100. , While tightening the tendon and surrounding leg. 1A and 1B show the position of the posterior leg M4. As is known from these FIGS. 1A and 1B, the tightening of the hind-leg tendon cloth 80L and the hind-leg tendon cloth 80R to the hind-leg tendon M4 can, for example, bring the effect.

As shown in FIG. 2D, in this embodiment, there is a lifting cloth 70L and a lifting cloth 70R above the hind leg cloth 80L and 80R, respectively. As described above, the lifting cloth 70L and the lifting cloth are used. The 70R holds the hips in place. As a result, the back leg tendon cloth 80L and the back leg tendon cloth 80R are reliably aligned with the back side of the thigh. In particular, in this embodiment, the posterior leg tendon cloth 80L and posterior leg tendon cloth 80R and the lifting cloth 70L and 70R are separate entities, and the upper leg posterior tendon cloth 80L and the upper leg posterior tendon cloth 80R and the lifting cloth 70L and Since the lower part of the cloth 70R is connected, the effect of the above alignment is remarkable.

In addition, in this embodiment, the elastic modulus in the longitudinal direction (approximately the up-down direction) of the hind-leg tendon cloth 80L and the posterior-leg tendon cloth 80R is smaller than that in the short-side direction (approximately the left-right direction), so that It's easiest to stretch in direction. As a result, it is difficult for the hind-leg tendon cloth 80L and the hind-leg tendon cloth 80R to hinder the expansion and contraction of the hind-leg tendon M4 in the vertical direction in which the hind-leg tendon M4 extends, so that the muscle strength of the hind-leg tendon M4 can be exerted appropriately.

<3. Features> According to the embodiment, an undergarment 100 including a base fabric 1 having a shape of a corset is provided. On the base fabric 1, a highly elastic pelvic fabric 50 covering the periphery of the pelvis in a band shape is sewn. Therefore, the pelvis of the wearer of the underwear 100 can be fastened and fixed by the fastening force of the pelvic cloth 50. The base fabric 1 is further sewn with a iliopsoas muscle cloth 60 covering the lumbosacral muscle M3 or the vicinity of the root of the thigh, and a hamstring muscle cloth 80 covering the back of the thigh tendon M4 or the back of the thigh. And the elasticity of the cloth 80 is higher than that of the base cloth 1. Therefore, a force that assists the expansion and contraction in the direction of the muscle fiber can be applied to the lumbo-sacral muscle M3 and the posterior leg tendon M4 of the underwear 100. As a result, the balance of the muscles around the pelvis can be maintained, and the pelvis can be guided to the correct inclination. Furthermore, the lower abdominal fabric 20A and the lower abdominal fabric 20B sewn on the base fabric 1 can also apply compression force to the abdominal muscle M2, and tighten the abdominal muscle M2 and its surroundings, thereby guiding the pelvis to The correct tilt.

<4. Modifications> An embodiment of the present invention has been described above, but the present invention is not limited to the embodiment, and various changes can be made without departing from the spirit thereof. For example, the following changes can be made. The gist of the following modification examples may be appropriately combined.

<4-2> In the above-mentioned embodiment, the base cloth 1 of the underwear 100 is superimposed on various cloths 20, 30, 40, 50, 60, 70, and 80, but the cloth 20 may be overlapped on the cloth 20. At least part of the cloth 30, cloth 40, cloth 50, cloth 60, cloth 70, and cloth 80 does not have the base cloth 1, but is connected to the base cloth 1 in a patch manner.

<4-3> In the above-mentioned embodiment, various support fabrics 20, support fabrics 40, support fabrics 50, support fabrics 60, support fabrics 70, and support fabrics 80 are set to have higher elasticity than the base fabric 1, but the support The elasticity of at least one of the cloth 20, the supporting cloth 40, the supporting cloth 50, the supporting cloth 60, the supporting cloth 70 and the supporting cloth 80 may not be higher than that of the base cloth 1. In this case, the supporting cloth 20, the supporting cloth 40, the supporting cloth 50, the supporting cloth 60, the supporting cloth 70, and the supporting cloth 80 are also merely required to overlap with other cloths (typically, the base cloth 1). By forming a part with elasticity higher than the base fabric 1 together with the cloth, the function of supporting a predetermined part of the body as described above can be exhibited. [Example]

The following underwear was prepared as an example, except that the configuration of making the iliopsoas muscle cloth 60L and the iliopsoas muscle cloth 60R the most difficult to expand and contract in the long side direction and the most easy to expand and contract in the short side direction was used. The underwear 100 of the embodiment is the same. Then, when the subject with the pelvic angle of 12.2 ° wore the underwear of the example, the pelvic angle was improved to 10 °. Furthermore, the pelvic angle is suitably 8 ° to 10 °. Here, it is used in conjunction with the "Orthopedic and Sports Injury Diagnosis Manual" (Chad Starkey et al., National Academic Press (National Academies Press, NAP (2012), page 89). Therefore, the pelvic correction effect of the underwear of the Example was confirmed.
