Description

Technical Field

[0001] The present invention relates to bottom clothing, and more particularly to bottom clothing such as shorts, girdles, supporters, swimsuits, spats, etc. that can effectively improve urine leakage by accurately supporting the pelvic floor muscles.

Background Art

[0002] Frequent urination and urine leakage in women are generally caused by the relaxation and weakening of the pelvic floor muscle group. Therefore, various types of shorts that support the pelvic floor muscle group to lift it have been proposed. For example, in Patent Document 1, in shorts having a front body whose upper end is connected to the waist portion, a back body whose upper end is connected to the waist portion, and a crotch portion disposed between the lower ends of the front body and the back body, a front stretch band made of an elastic material inside the shorts, a crotch band made of a water-absorbing material connected to the front stretch band, and a back body stretch band made of an elastic material connected to the crotch band are connected to form a single stretch band having elasticity. The front stretch band of the stretch band is continuously provided at the waist portion corresponding to the front body of the shorts, and the rear stretch band of the stretch band is connected to the waist portion corresponding to the back body of the shorts. The shorts disclosed in Patent Document 1 use an elastic stretch band that hangs down inside the shorts to push up the pelvic floor muscles when worn, thereby enhancing the awareness of the pelvic floor muscles. By consciously taking a posture (exercise) to strengthen the muscle strength, the decrease in the strength of the pelvic floor muscles can be suppressed, visceral prolapse can be prevented, and the anxiety of urinary incontinence can be eliminated. It is described that the quality of life can be improved by actively performing actions such as going out and sports.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Thus, conventional panties for pelvic floor muscle support have been developed based on the technical idea of enhancing the awareness of the pelvic floor muscles by pushing up and holding the weakened and less elastic pelvic floor muscles. However, since the pelvic floor muscles, which are inner muscles, are not easily moved by the wearer's conscious effort. Therefore, an object of the present invention is to provide bottom wear that can effectively reduce urine leakage, improve the posture of the wearer, and support comfortable walking by supporting effective awareness of the pelvic floor muscles.

Means for Solving the Problems

[0005] As a result of intensive research in view of the above problems, the present inventor has found that by applying appropriate pressure to at least two locations including the ischium among the pubis, ischium, and coccyx, it is possible to prevent the pelvis from tilting backward and make the wearer aware of standing the pelvis in the correct position. Moreover, due to the synergistic effect with the pressing effect on the pubis and / or coccyx, urine leakage can be effectively reduced, the posture of the wearer can be improved, and comfortable walking can be supported, thus completing the present invention. That is, the bottom wear of the present invention is bottom wear having a front part, a back part, and a crotch part, and includes at least two pressing parts including a first pressing part disposed in a range covering at least a part of the pubis below the front part, a second pressing part disposed in a range covering at least a part of each of the left and right ischia below the back part, and a third pressing part disposed in a range covering at least a part of the coccyx on the back part.

[0006] The first pressing member is preferably disposed in a range covering the center of the pubis. Further, the third pressing member may have a base portion extending vertically upward from below the back part to a predetermined height, a left inclined portion disposed above the base portion and inclined to the left and extending upward, and a right inclined portion disposed above the base portion and inclined to the right and extending upward.

Advantages of the Invention

[0007] The bottom clothing of the present invention is characterized in that appropriate pressure is applied to at least two locations including the ischium among the pubis, ischium, and coccyx of the wearer. By pressing the ischium, it is possible to prevent the pelvis from tilting backward and make the wearer aware of standing the pelvis in the correct position. In addition to the ischium, by pressing either the pubis or the coccyx, the synergistic effect thereof can effectively reduce urine leakage. Further, the bottom clothing of the present invention can improve the posture of the wearer and also obtain the effect of supporting more comfortable walking, such as widening the stride length during walking and making it easier to lift the legs. In addition to the ischium, by pressing both the pubis and the coccyx, it is possible to make the wearer exert force on the lower abdomen (transverse abdominal muscle). Further, by holding the coccyx and the pubis from the front and back, the pelvis becomes more stable. Due to these synergistic effects, in the configuration where pressure is applied to three locations of the pubis, ischium, and coccyx, the weakened pelvic floor muscles can be stretched and contracted, and by correcting the pelvis to the correct position, a more excellent urine leakage reduction effect, posture improvement effect, and walking support effect can be stably realized.

MODE FOR CARRYING OUT THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, "upper", "lower", "right", "left", "front" and "rear" in this specification correspond to "upper", "lower", "right", "left", "front" and "rear" of the body of the wearer wearing the bottom clothing of the present invention, respectively. In the following, unless otherwise specified, the vertical direction of the wearer's body, that is, the vertical direction is referred to as the "longitudinal direction", and the horizontal direction of the wearer's body, that is, the horizontal direction is referred to as the "lateral direction". Further, the "stretching direction" of the fabric in this specification or the fabric "stretches in a predetermined direction" indicates the direction in which the fabric used for each part is likely to stretch. However, unless otherwise specified, it does not exclude having stretchability in a direction other than the "stretching direction" or the "stretching" direction. In addition, in this specification of the present application, "pressing member" and "pressing part" are used in substantially the same meaning. However, the "pressing part" is also used when representing a part of one member, for example, when the second pressing member and the third pressing member are integrated, the part pressing the coccyx is referred to as the "second pressing part", and the part pressing the ischium is referred to as the "third pressing part".

[0010] In the following embodiments, the configuration of the present invention will be described by taking shorts as an example. However, the present invention can also be applied to bottom clothing such as girdles, supporters (pelvic supporters), swimsuits, and spats in addition to shorts. In addition, in the following embodiments, normal leg type shorts with a hem cut along the groin (the base of the leg) will be described as an example. However, the configuration of the present invention can also be applied to high leg type shorts where the leg cut is at a position higher than the base of the leg, and low leg type shorts where the hem is cut horizontally under the hip. Furthermore, the configuration of the present invention can be suitably used regardless of the length of the hem of bottom wear such as girdles that include at least a part of the thigh and cover the area from the waist to above the knees, and spats that reach the ankles.

[0011] The bottom wear of the present invention is characterized in that it can effectively reduce urine leakage by applying appropriate pressure to two locations including the ischium among the pubis, ischium, and coccyx to stimulate and stretch the weakened pelvic floor muscles. Hereinafter, the details of the first pressing member, the second pressing member, and the third pressing member for pressing the pubis, ischium, and coccyx respectively will be described. (1) The first pressing member The first pressing member of the present invention is arranged to press the pubis of the wearer. The pubis is a bone located at the lower front of the hip bone that forms both sides of the pelvis, and the left and right pubes are connected by the pubic symphysis. The first pressing member of the present invention is arranged in a range covering at least a part of each of the left and right pubes on the lower side of the front part of the bottom wear body, and preferably in a range covering at least a part of each of the left and right pubes including the center of the pubis. By pressing the pubis, it is possible to act on the wearer to apply force to the lower abdomen (transverse abdominal muscle). (2) The second pressing member The second pressing member of the present invention is arranged to press the ischium of the wearer. The ischium is a bone located at the lower rear of the hip bone that forms both sides of the pelvis, and there are two ischia in the human body. The second pressing member of the present invention is arranged in a range covering at least a part of each of the left and right ischia on the lower side of the back part of the bottom wear body. By pressing the ischium, it is possible to prevent the pelvis from tilting backward and make the wearer aware of standing the pelvis in the correct position. (3) The third pressing member The third pressing member of the present invention is arranged to press the coccyx of the wearer. The coccyx forms the rear surface of the pelvis together with the sacrum and was originally a bone that existed as a continuation of the spine. The third pressing member of the present invention is arranged in a range of the back part of the bottom clothing body that covers at least a part of the coccyx. In combination with the above-mentioned pressing of the pubis, by pressing the coccyx and the pubis from the front and back, the pelvis can be stabilized.

[0012] In the configuration of the present invention in which the first pressing member and the second pressing member are installed, an excellent stride increasing effect and a sufficient posture improving effect are realized. Also, in the configuration of the present invention in which the second pressing member and the third pressing member are installed, an excellent posture improving effect and a stride increasing effect can be obtained. In the bottom clothing of the present invention having the above-described excellent posture improving effect and stride increasing effect, it is possible to support so as to effectively raise awareness of the pelvic floor muscles, and effectively reduce urinary leakage. In addition, in a configuration including the first pressing member in addition to the second pressing member, since the lower abdomen is pressed, a more excellent urinary leakage reducing effect is realized. The above effects are considered to be due to a synergistic effect of pressing the ischium and the pubis, or the ischium and the coccyx, and it is difficult to realize in a configuration in which the first pressing member, the second pressing member, and the third pressing member are installed alone, and a configuration in which the first pressing member and the third pressing member are installed. In the configuration of the present invention in which the first pressing member, the second pressing member, and the third pressing member are installed, a more excellent posture improving effect and stride increasing effect can be obtained. This is considered to be a synergistic effect due to three-point support of the pubis, ischium, and coccyx, and in the above configuration, a more stable and excellent posture improving effect, stride increasing effect, and urinary leakage reducing effect can be realized. In addition, in the panties of the present invention having the above configuration, it has been confirmed that the posture improving effect is improved, the stride at the time of wearing is increased, and the wearing comfort is also improved as compared with conventional hammock-style panties.

[0013] As described above, among the first pressing member, the second pressing member, and the third pressing member, by installing at least two pressing members including the second pressing member, the effects of the present invention can be obtained. Hereinafter, the configuration of the shorts provided with the first pressing member, the second pressing member, and the third pressing member will be described based on an example. 1. First Embodiment FIG. 1 is a view showing the front surface (outer side) (A) and the back surface (outer side) (B) of the shorts according to the first embodiment of the present invention. Further, FIG. 2 is a view showing the front back surface (skin side) (A) and the back back surface (skin side) (B) of the shorts of the present embodiment.

[0014] As shown in FIGS. 1 and 2, the shorts body 1 of the present embodiment includes a front portion 2 disposed on the front surface of the shorts body 1 and covering the lower abdomen of the wearer, a back portion 4 disposed on the back surface of the shorts body 1 and covering the buttocks of the wearer, a crotch portion 3 connecting the lower ends of the front portion 2 and the back portion 4, and left and right side portions 5a, 5b disposed between the left and right ends of the front portion 2 and the left and right ends of the back portion 4, which are sewn together. In the present embodiment, the shorts body 1 is made of cotton jersey, but the material of the bottom clothing body of the present invention is not limited thereto, and any material having a desired stretching direction and stretchability can be adopted. In particular, it is preferable to adopt knitted fabrics including cotton jersey, smooth, and Russell. Further, for example, if the bottom clothing is incontinence shorts, a material such as a water-absorbing and water-repellent material can be selected, and if it is a girdle, a power net or a satin net can be selected, and the material of the bottom clothing body can be selected according to the use of the bottom clothing. A pad made of a material such as cotton cloth, mesh, or water-absorbing and water-repellent material can be overlapped and disposed on the skin side of the crotch portion 3.

[0015] As described above, in this embodiment, the front part 2, the back part 4, the crotch part 3, and the side parts 5a and 5b are sewn together to form the short body 1. However, this embodiment is not limited to the structure of the bottom clothing body of the above embodiment as long as it is configured to be able to arrange the first, second, and third pressing members described below. It can be applied to various bottom clothing such as seamless shorts without seams, seamless shorts with few seams, and girdles formed by sewing together more members than in the above embodiment.

[0016] As shown in FIGS. 2(A) and 3, the first pressing member 6 of this embodiment has a substantially T shape and is installed below the back side of the front part 2 of the short body 1. The left and right end parts 6b, 6b of the first pressing member 6 conform to the shapes of the left and right end parts of the front part 2 of the short body 1 and are sewn to the sewing parts with the left and right end parts of the left and right side parts 5a, 5b corresponding to the left and right end parts of the front part 2. The end parts 6c, 6c connected to the lower sides of the left and right end parts 6b, 6b of the first pressing member 6 conform to the shape of the leg hole part of the front part 2 and are sewn to the leg hole part of the front part 2. Further, the lower end 6d of the first pressing member 6 conforms to the shape of the lower end of the front part 2 and is arranged adjacent to the front end part of the crotch part 3 and is sewn together. The upper end 6a of the first pressing member 6 has a convex curved shape downward and is sewn to the front part 2. In this embodiment, the first pressing member 6 is made of power net. The material of the first pressing member 6 is not limited to this, but in order to effectively apply pressure to the pubis and stimulate it, it is preferable to use a highly stretchable material. Such fabrics include, in addition to power net, satin net, 2Way tricot fabric, stretch lace, Triskin (registered trademark), and the like.

[0017] In this embodiment, a first pressing member 6 that is long in the horizontal direction and made of a highly stretchable material is installed below the front part 2 of the short body 1, covering the left and right pubises including the center of the wearer's pubis, so that it is possible to effectively apply pressure to the pubis and stimulate it. The first pressing member 6 of the present embodiment is installed in a range that includes the center of the pubic bone and covers at least a part of the left and right pubic bones. However, its shape, area, and the position where it is arranged are not limited to the above configuration. Note that since the position of the center of the pubic bone varies among individuals depending on the wearer, it cannot be generally determined. However, the horizontal center is located near the center of the front part of the shorts. On the other hand, the vertical (height) center of the pubic bone is usually located in the range of 20 mm to 70 mm above the joint between the front part 2 and the crotch part 3 in shorts with a general design like the present embodiment. More generally, it is located in the range of 30 mm to 60 mm above the joint between the front part 2 and the crotch part 3 (corresponding to the range of h1 in FIG. 3). The first pressing member 6 is preferably installed in a range that includes at least a part of the above range, and more preferably installed in a range that includes the entire above range. In the present embodiment, the first pressing member 6 is arranged over the entire range 85 mm above the joint between the front part 2 and the crotch part 3 (corresponding to the solid line part of h2 in FIG. 3), covering the entire range of the position of the center of the pubic bone described above. Therefore, in the present embodiment, the pubic bone can be pressed more effectively by the first pressing member 6. The position of the upper end of the first pressing member 6 is not particularly limited as long as it includes the range of the position of the center of the pubic bone described above. However, even if the position of the upper end of the first pressing member 6 exceeds 110 mm, no further pressing effect can be expected, and conversely, there is a possibility that the pressing force will be dispersed. Therefore, the upper limit of the position of the upper end of the first pressing member 6 is preferably 110 mm above the joint between the front part 2 and the crotch part 3 (corresponding to the sum of the solid line part and the broken line part of h2 in FIG. 3). In the present embodiment, the shape of the first pressing member 6 is not particularly limited as long as it is installed in a range that covers at least a part of the pubic bone, and more preferably, the range that covers the center of the pubic bone described above. For example, it can be circular, polygonal, elliptical, etc. with the center of the pubic bone as the center point. Here, by making the shape of the first pressing member 6 long in the horizontal direction, the area covering the pubic bone becomes wider, so it is possible to cover the difference in the position of the pubic bone due to individual differences among wearers. The area of the first pressing member 6 of the present embodiment can be appropriately designed according to the stretchability of the material constituting the pressing member and the like. However, applying a low pressure over a wide range (surface) is preferable to applying a high pressure in a narrow range (point) because it can achieve pressurization while reducing the feeling of tightness during wearing. For example, in the shorts of the present embodiment, by setting the area of the first pressing member to 30 to 60% with the entire area of the front portion of the shorts body being 100%, a more excellent effect can be obtained.

[0018] In the first embodiment, the first pressing member made of a single member (fabric) is used, but the form of the first pressing portion is not limited to this, and it can also be configured by a plurality of members. For example, as shown in FIGS. 4(A) and 4(B), the member covering the right pubis and the member covering the left pubis can be arranged as separate members. In FIG. 4(A), the first pressing member 6r1 on the right side and the first pressing member 6l1 on the left side are arranged so as to be adjacent to each other near the center of the pubis. Here, the effects of the present invention can be obtained as long as the range including the vicinity of the center of the pubis is covered even if the left and right first pressing members 6r1 and 6l1 are separated, but the left and right first pressing members 6r1 and 6l1 are preferably arranged as closely as possible so as to surely cover the range including the pubis center. Further, in FIG. 4(B), the first pressing member 6r2 on the right side and the first pressing member 6l2 on the left side are configured to overlap in the range including the center of the pubis. Even with such a configuration, the effects of the present invention can be obtained.

[0019] As shown in FIGS. 2(B) and 5, the second pressing member 7 of the present embodiment is substantially trapezoidal and is installed below the back side of the back portion 4 of the shorts body 1. The left and right end portions 7b, 7b of the second pressing member 7 conform to the shape of the crotch portion of the back portion 4 and are sewn to the crotch portion of the back portion 4. Further, the lower end 7c of the second pressing member 7 conforms to the shape of the lower end of the back portion 4 and is arranged adjacent to the rear end portion of the crotch portion 3 and is sewn together. The vicinity of the horizontal center of the upper end 6a of the second pressing member 7 protrudes upward, and from the central protrusion of the upper end of the second pressing member 7 to the left and right end portions, it is convex downward in a curved shape and is sewn to the back portion 4. The second pressing member 7 is also made of power net, like the first pressing member 6. The material of the second pressing member 7 is not limited to this, but it is preferable to use a material with high stretchability in order to effectively apply pressure to and stimulate the ischial bones. The same material as the first pressing member 6 described above can be used as such a fabric.

[0020] In this embodiment, a second pressing member 7 that is long in the horizontal direction and made of a highly stretchable material is placed below the back portion 4 of the shorts body 1, and covers the wearer's left and right ischia, making it possible to effectively apply pressure to and stimulate the ischia. The shape, area and location of the second pressing member 7 of this embodiment are not limited to the above configuration, so long as it is installed in a range covering at least a part of each of the left and right ischia. The location of the ischia cannot be determined in general because it varies from wearer to wearer, but in shorts with a general design like this embodiment, the vertical location of the ischia is usually in the range of 10 mm to 60 mm above the joining part of the back part 4 and the crotch part 3 (corresponding to the range h3 in FIG. 5(B)). Therefore, it is preferable that the second pressing member 7 is installed in a range including at least a part of the above range, and it is more preferable that it is installed in a range including the entire range. In this embodiment, the second pressing member 7 is disposed over almost the entire range of 70 mm above the joint between the back part 4 and the crotch part 3, and covers the entire range of the vertical position of the ischial bones described above. Therefore, in this embodiment, the second pressing member 7 can effectively press the ischial bones. As long as the above-mentioned range of the vertical position of the ischium is included, the position of the upper end of the second pressing member 7 is not particularly limited. However, even if the position of the upper end of the second pressing member 7 exceeds 90 mm, no further pressing effect can be expected, and conversely, there is a possibility that the pressing force will be dispersed, so that the upper limit of the position of the upper end of the second pressing member 7 is preferably set to 90 mm above the joining part of the back part 4 and the crotch part 3 (corresponding to the sum of the solid line part and the dashed line part of h4 in FIG. 5(B)). As described above, the shape of the second pressing member 7 of the present embodiment is not particularly limited as long as it includes a range covering at least a part of the left and right ischiums, and can be, for example, circular, polygonal, elliptical, or the like. Here, by making the shape of the second pressing member 7 long in the lateral direction, the area covering the ischium becomes wider, so that it is possible to cover the difference in the position of the pubis due to individual differences among the wearers. Also, in the present embodiment, the second pressing member 7 is composed of a single member that covers the range including both the left and right ischiums. However, the second pressing member 7 can also be composed of a plurality of members. For example, a member covering the right ischium and a member covering the left ischium can be installed adjacent to each other or separately as different members. The area of the second pressing member 7 of the present invention can be appropriately designed according to the stretchability of the material constituting the pressing member and the like. However, it is preferable to apply a low pressure over a wide range (surface) rather than applying a high pressure in a narrow range (point) because it can achieve pressurization while reducing the sense of tightness during wearing. For example, in the shorts of the present embodiment, by setting the area of the second pressing member to 30 to 60% with the entire area of the back portion of the shorts body being 100%, a more excellent effect can be obtained.

[0021] As shown in FIGS. 2(B) and 5, the third pressing member 8 of the present embodiment is composed of two pressing members (left pressing member 8a and right pressing member 8b), and is installed on the back side of the back portion 4 of the shorts body 1. The lower ends of the two pressing members 8a and 8b are both sewn near the center of the joint portion between the lower end of the back portion 4 and the back side end of the crotch portion 3. The two pressing members 8a and 8b have the same shape and are sewn on the back portion 4 overlapping each other from the lower end to a predetermined height h5. Above the point at height h5 from the lower end, the left pressing member 8a inclines toward the left, the right pressing member 8b inclines toward the right, and the two pressing members 8a and 8b branch at the point at height h2 from the lower end. Then, the upper ends of the left pressing member 8a and the right pressing member 8b are sewn to the upper end of the back portion 4. Here, the distance between the right end of the upper end of the left pressing member 8a and the left end of the upper end of the right pressing member 8b is d, and the two are separated. In the present embodiment, d is set to 65 mm. As described above, the third pressing member 8 of the present embodiment includes a base portion that vertically extends upward from the lower end to a predetermined height (h5), and a left third pressing member 8a having a left inclined portion that extends upward while inclining toward the left from the predetermined height (h5), and a right third pressing member 8b having a base portion that vertically extends upward from the lower end to a predetermined height (h5) and a right inclined portion that extends upward while inclining toward the right from the predetermined height (h5).

[0022] Since the coccyx of a normal wearer exists in the range from the lower end of the third pressing member 8 to the branch point of the left and right third pressing members 8a and 8b, that is, in the range from the lower end to the height of h6, if the third pressing member 8 is installed in this range, pressure can be accurately applied to the coccyx. Therefore, it is not necessary to install the third pressing member 8 over the entire vertical direction of the short body as in the present embodiment. However, considering covering the difference in the coccyx position due to individual differences among wearers and the ease of manufacturing, etc., it is preferable that the third pressing member 8 is installed in the range from the lower end to the upper end of the short body 1. Also, in the present embodiment, above the third pressing member 8, the left and right members are arranged to be separated. However, in order to obtain the effects of the present invention, the third pressing member 8 does not need to be separated left and right, and the base portion can also be configured to vertically extend to the upper end. However, in order to reduce the tightening feeling at the waist portion, it is preferable that the upper part of the third pressing member 8 is configured to be separated left and right as in the present embodiment.

[0023] Both the left and right third pressing members 8a and 8b are made of power net. Although the material of the third pressing member 8 is not limited to this, in order to effectively apply pressure to the coccyx and stimulate it, it is preferable to use a highly stretchable material. As the material of the third pressing member 8, the same materials as those of the first pressing member 6 and the second pressing member can be used.

[0024] The area of the third pressing member 8 of the present embodiment can be appropriately designed according to the stretchability of the material constituting the pressing member. However, it is preferable to apply a low pressure over a wide range (surface) rather than applying a high pressure in a narrow range (point) because it is possible to achieve pressurization while reducing the feeling of tightness during wearing. For example, in the shorts of the present embodiment, by setting the total area of the back surface portion of the short body to 100% and the total area of the third pressing member to 15% to 25%, a more excellent effect can be obtained. Note that the area of the overlapping portion of the left and right third pressing members 8a and 8b is preferably 5% to 15% with respect to the total area of the back surface portion of the short body as 100%. Further, in the shorts of the present embodiment, the lateral width (lateral width at the height h5) of the base portion of the third pressing member 8 is preferably 10% to 35% of the longest lateral width of the back surface portion. By setting the lateral width of the base portion within the above range, the coccyx can be pressed more effectively. In the present embodiment, the longest lateral width of the back surface portion is designed to be about 350 mm, and the lateral width of the base portion is designed to be about 80 mm.

[0025] In the present embodiment, as described above, by installing the first pressing member 6 on the front surface portion 2 of the short body 1 and installing the second pressing member 7 and the third pressing member 8 on the back surface portion 4, it is possible to effectively apply pressure to the pubis, ischium, and coccyx of the wearer. Due to this stimulation, the pelvic floor muscles contract and relax, and thus urine leakage can be effectively reduced.

[0026] 2. Second Embodiment FIG. 6 is a diagram showing the front surface (outer side) (A) and the back surface (outer side) (B) of the shorts according to the second embodiment of the present invention. FIG. 7 is a diagram showing the front back surface (skin side) (A) and the back back surface (skin side) (B) of the shorts of the present embodiment. Hereinafter, the same configurations as those in the first embodiment will be omitted, and only the different configurations will be described.

[0027] As shown in FIGS. 6 and 7, the short body 10 of the second embodiment is seamless and does not use threads, and is finished by adhering between members with an adhesive. Note that stretch lace (russell) is used as the material of the short body 10 of the present embodiment. As shown in FIG. 7(A), also in the second embodiment, a substantially T-shaped first pressing member 60 is installed below the front portion. The shape and size of the first pressing member 60 are designed to cover at least a part of the pubis including the center of the pubis, similar to the first embodiment. In the present embodiment, the first pressing member 60 is also attached with an adhesive. Here, for example, a cotton cloth is adhered to the back side of the crotch portion of the short body 10. In the present embodiment, due to manufacturing constraints, the adhesive portions cannot be overlapped, so the first pressing member 60 is installed with a predetermined interval (c1) between the lower end of the first pressing member 60 and the front side end of the crotch portion. In the present embodiment, c1 is 2 mm. Further, in the short body of the present embodiment, the front portion and the back portion are joined using an adhesive. For this reason, a predetermined interval (c2) is provided between the first pressing member 60 and the left and right ends of the first pressing member 60 and the joint portion (side joint portion) between the front portion and the back portion. In the present embodiment, c2 is 20 mm to 23 mm. As described above, in the present embodiment, due to manufacturing constraints, the first pressing member 60 is installed at a predetermined interval from the crotch or the joint portion between the front portion and the back portion. However, even if there are no manufacturing constraints and the two are arranged closely, the effects of the present invention can be obtained. Note that in this specification and the like, installing at a predetermined interval from a predetermined position as described above is also included in "installing adjacent to".

[0028] As shown in FIG. 7(B), in the second embodiment, a pressing member in which the second pressing member 70 and the third pressing members 80a, 80b, 80c are integrated is attached to the back portion by adhesion. Even in the configuration where the first pressing member 60 is attached to the front surface portion of the short body 10 and the pressing member in which the second pressing member and the third pressing member are integrated is attached to the back surface portion with an adhesive as in the present embodiment, pressure can be applied to the pubic bone, ischium, and coccyx of the wearer. And by this stimulation, the pelvic floor muscles contract and relax, so that urine leakage can be effectively reduced. Further, in the configuration using an adhesive without sewing as in the present embodiment, skin stress such as a prickly feeling and itching due to seams is reduced.

Example

[0029] Hereinafter, embodiments of the present invention will be described in more detail with reference to examples, but the present invention is not limited by these examples.

[0030] 1. Posture improvement effect Subjects when wearing a conventional short without a pressing member and a backing cloth and a short of the first embodiment were photographed from the side. From each photograph, the angle (θ) formed by the horizontal plane (H) and the straight line (Roser-Nélaton line) passing through the ischial tuberosity, the upper edge of the greater trochanter, and the anterior superior iliac spine was measured. In a correct (normal) posture, the angle θ is about 45°.

[0031] FIG. 8 shows the silhouette (A) when wearing a conventional short and the silhouette (B) when wearing a short of the first embodiment of the present invention. The θ when wearing a conventional short was 33°, whereas when wearing a short of the first embodiment of the present invention, θ widened significantly and became 45°. From the above results, it was found that the shorts of the present invention having the first pressing member, the second pressing member, and the third pressing member can obtain a remarkable effect of improving the posture of the wearer. As described above, the second pressing member that presses the ischium can prevent the pelvis from tilting backward and can make the wearer aware of standing the pelvis in the correct position. In addition, the first pressing member that presses the pubis can work to make the wearer apply force to the lower abdomen (transversus abdominis). Furthermore, the third pressing member that presses the coccyx of the wearer can further stabilize the pelvis by pressing the coccyx and the pubis from the front and back together with the first pressing member. It is considered that these synergistic effects have realized the above excellent posture improving effect.

[0032] 2. Stride measurement When the subject walked straight forward 10 steps naturally from a predetermined position, the distance from the heel contact of the third step to the heel contact of the ninth step was measured, and the distance per step was calculated as the stride. When the conventional shorts and the shorts of the first embodiment were worn and the same measurement was performed, as a result, when wearing the shorts of the first embodiment, the stride increased by 29% compared to the case of wearing the conventional shorts. From this, it was confirmed that the configuration of the present invention can obtain an excellent stride increasing effect.
