This is a U.S. National Phase Application under 35 U.S.C. §371 of International Patent Application No. PCT/JP2005/009063 filed May 18, 2005, and claims the benefit of Japanese Patent Application No. 2004-150906, filed May 20, 2004, both of which are incorporated by reference herein as if set forth in their entirety. The International Application was published in Japanese on Dec. 1, 2005 as WO 2005/112674 A1 under PCT Article 21(2).
The present invention relates to a bottom garment used for lifting up the buttocks.
Japanese Patent Application Laid-Open No. 2002-212814 discloses a garment for leg strength enhancement which enhances the desired muscles easily only by living an ordinary life. On this garment for leg strength enhancement, a strong elastic portion is disposed in a direction extending along a muscle to directly give a load to the muscle from this strong elastic portion, whereby the muscle strength is enhanced. Specifically, by providing a load directly to an enhancement-target muscle, the muscle is developed.
An object of the garment for leg strength enforcement described in Japanese Patent Application Laid-Open No. 2002-212814 is to enhance the muscle strength of the section where the strong elastic portion is disposed, thus it is not always possible to obtain a beautiful figure. For example, as shown in FIG. 2 in Japanese Patent Application Laid-Open No. 2002-212814, an elongated strip-shaped strong elastic portion is provided on each buttock. However, in this case, only the strength of the muscles around the buttocks where the strong elastic portions are disposed is enhanced. Therefore, in this case, it is difficult to lift up the buttocks neatly.
An object of the present invention therefore is to provide a bottom garment capable of lifting up the buttocks neatly.
The bottom garment of the present invention is characterized in comprising tightening portions at a section corresponding to a middle point between the interspinal point and the patellar midpoint of the human body, the middle point being located on a front side of a thigh. When such a bottom garment is worn, the tightening portions abut on the section corresponding to the middle point between the interspinal point and the patellar midpoint of the human body, thus strong locking force can be added to the quadriceps located in this section. Accordingly, the quadriceps is stimulated, thus naturally the leg can be raised backward significantly so that the gluteus maximus muscle is used. Therefore, by wearing the bottom garment of the present invention, a beautiful hipline can be formed easily.
In the bottom garment of the present invention, preferably the wearing pressure, when the garment is worn, at the tightening portions is at least 30 [gf/cm2], the wearing pressure, when the garment is worn, at sections other than the tightening portions is equal to or less than 30 [gf/cm2], and the differential pressure between the pressure at the tightening portions and the wearing pressure, when the garment is worn, at the sections other than the tightening portions is at least 10 [gf/cm2]. Accordingly, the quadriceps can be stimulated without applying a feeling of tightness to the wearer. Therefore, a bottom garment in which the gluteus maximus muscle can be used and which does not provide a feeling of tightness to the wearer can be provided.
In the bottom garment of the present invention, preferably the tightening portions intersect with each other at the section corresponding to the middle point. Accordingly, the intersecting part of the tightening portions is applied with a stronger tightening force, whereby the section corresponding to the middle point between the interspinal point and patellar midpoint can be further stimulated. Therefore, a more beautiful hipline can be formed more easily.
In the bottom garment of the present invention, preferably, the relationship among the wearing pressure, when the garment is worn, at the intersecting part of the tightening portions, the pressure at a section in the tightening portions other than the intersecting part, and the wearing pressure, when the garment is worn, at a section other than the tightening portions, when the garment is worn, is expressed as “the wearing pressure, when the garment is worn, at the intersecting part>the pressure at the section in the tightening portions other than the intersecting part, when the garment is worn>the pressure at the section other than the tightening portions, when the garment is worn. Moreover, preferably the wearing pressure, when the garment is worn, at the intersecting part of the tightening portions is 30 through 60 [gf/cm2], the pressure at the section in the tightening portions other than the intersecting part is 15 through 50 [gf/cm2], and the wearing pressure, when the garment is worn, at the section other than the tightening portions is 0 through 30 [gf/cm2]. Accordingly, the quadriceps can be stimulated without applying a feeling of tightness to the wearer. Therefore, a bottom garment in which the gluteus maximus muscle can be used and which does not provide a feeling of tightness to the wearer can be provided.
In the bottom garment of the present invention, preferably the wearing pressure, when the garment is worn, at the intersecting part of the tightening portions is 1.2 through 3.7 times the pressures at eight peripheral regions of an upper side, upper right side, right side, lower right side, lower side, lower left side, left side, and upper left side with respect to the intersecting part. Moreover, the wearing pressure, when the garment is worn, at the intersecting part of the tightening portions is preferably 1.2 through 1.6 times the wearing pressure, when the garment is worn, at a peripheral region of the eight peripheral regions, which is on the tightening portions, and is preferably 1.9 through 3.7 times the wearing pressure, when the garment is worn, at a peripheral region of the eight peripheral regions, which is located in a section other than the tightening portions. Accordingly, the quadriceps can be stimulated without applying a feeling of tightness to the wearer. Therefore, a bottom garment in which the gluteus maximus muscle can be used and which does not provide a feeling of tightness to the wearer can be provided.
In the bottom garment of the present invention, preferably the middle point is located within an area in which the ratio between the length extending from the interspinal point to the middle point and the length extending from the middle point to the patellar midpoint is 4:6 through 6:4. Accordingly, the intersecting part of the tightening portion can be positioned at substantially the center of the quadriceps, so that the quadriceps can be stimulated effectively.
According to the bottom garment of the present invention, an excellent effect that the buttocks can be lifted up neatly and easily can be expected.
Before explaining the embodiment, firm buttocks (beautiful hipline) as a background of the invention of the present application is described with reference to
In order to realize firm buttocks, the inventors of the present application have focused attention on the fact that firm buttocks can be achieved by exercising the gluteus maximus muscles. Here, the gluteus maximus muscles are the muscles exercised by raising the legs backward widely. Therefore, by widely kicking the legs backward when walking, the gluteus maximus muscles can be exercised, and firm buttocks can be achieved.
There are a number of people who want to tighten their buttocks, and many of them try to walk on regular basis in order to maintain their figures. The inventors of the present application therefore have discovered that, if a walking for tightening the buttocks, i.e. a walking by largely kicking legs backward, can be performed on regular basis, tight buttocks can be realized simply by performing such walking, and thus have completed the present invention.
Hereinafter, the embodiment of the present invention is described with reference to the drawings. It should be noted that the same reference numerals are used to indicate the same elements, thus the overlapping explanations are omitted accordingly.
From the perspective of the above explanations, the inventors of the present application have created a bottom garment shown in
Next,
Here, since the filler clothes 3a and 3b are formed to intersect with each other are in the form of strips, the muscles can be stimulated without impeding the functions of the muscles. Therefore, as shown in
When the extension movements of the knees increase, a blow knee region is swung upward in a direction of an arrow D2 as shown in
Next, the position of the filler cloth intersecting part 3ab is described with reference to
Next,
As shown in
Next, the bottom garment shown in
Here, the length between the interspinal point 21 and the middle point between the interspinal point 21 and the patellar midpoint 22 of each tester is 20.7 [cm] through 23.9 [cm] (see
Next,
In a sample A shown in
Five testers are allowed to wear these samples A through F to perform an experiment for judging whether each of the samples A through F provides effective advantages on the gluteus maximus muscles. This experiment was performed under the following conditions. The wearers of the samples A through F were caused to walk on a treadmill at a speed of 4.2 km/h and an electromyography is used to perform measurement of the myoelectric potentials of the gluteus maximus muscles one minute after the walking is started. On the basis of the electromyograms obtained as a result of this measurement, the value of the RMS (Root Mean Square) during 16 seconds after the start of the measurement was calculated to derive the discharged amount of the gluteus maximus muscles. It should be noted that when obtaining the RMS value, 5 hz or lower component and 250 hz or higher component were cut from the components shown in the electromyogram.
The inventors of the present application decided to judge whether effective advantages are observed on the gluteus maximus muscles by judging whether the discharged amount in each of the samples A through E forming the filler clothes 3 is higher than the discharged amount in the sample F which does not form the filler clothes 3. Specifically, if the discharged amount in each of the samples A through E is larger than the discharged amount in the sample F, it is judged that effective advantages are obtained in the gluteus maximus muscles.
As a result of the above experiment, although the discharged amount in the sample A was lower than the discharged amount in the sample F, the discharge amount of each of the samples B through E was higher than the discharged amount in the sample F. Therefore, the inventors of the present application have judged that effective advantages are obtained in the gluteus maximus muscles in the samples B through E. It should be noted that in this experiment, in addition to the discharged amount of the gluteus maximus muscles, the myoelectirc potentials of hamstring muscles (general term for biceps muscles, semitendinosus muscle, and semimembranosus muscle) were measured. As a result, it was discovered that, for the discharged amount of the hamstring muscles, the discharged amount of each of the samples B through E was larger than the discharged amount in the sample F, as with the case of the discharged amount of the gluteus maximus muscles. Specifically, it was discovered that the samples B through E are also effective in an exercise of kicking the legs backward. From these facts as well, it is clear that the samples B through E provide effective advantages in the gluteus maximus muscles.
Next, each of the samples A through F was put on the dummy M to measure the pressure applied to a predetermined measuring point on each of the samples A through F. The wearing pressure, when the garment is worn, in this case means the wearing pressure, when the garment is worn, received from the bottom garment. It should be noted that the measuring point in the present embodiment is the filler cloth intersecting par 3ab and a rear side section of a thigh on which the filler clothes are not formed.
The measuring device used in the measurement of the pressure at the measuring points is a contact pressure measuring device (airpack type) manufactured by AMI Co., Ltd. The specifications thereof are as follows: table type: AMI 3037-20; sensor section: 20 [mm] diameter; maximum measured value: approximately 15000 [Pa]; guide tube: 1.5 [m]. Further, in a method of measuring the wearing pressure, when the garment is worn, for example, a pressure sensor is attached to the dummy or a measuring section on a human body to measure the pressure applied from the bottom garment to the pressure sensor in a state in which the bottom garment is worn.
As a result of the experiment performed using the samples A through F, the following characteristics were discovered in regards to the tightening force of the main body portion 2 and the tightening force of the filler clothes 3.
(1) If the tightening force of the main body portion 2 is weak no effective advantage for the gluteus maximus muscles can be expected. (2) The stronger the tightening force of the filler clothes 3, the larger the effects on the gluteus maximus muscles.
As described above, the inventors of the present applications have reached a conclusion that if the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab is less than 30 [gf/cm2], effective advantages can hardly be expected on the gluteus maximus muscles, and if the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab exceeds 60 [gf/cm2], effects on the gluteus maximus muscles are significant but the wearers have a large feeling of tightness. Specifically, the inventors of the present application considered that if the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab is approximately 30 through 60 [gf/cm2], the bottom garment in which the gluteus maximus muscles are affected advantageously and the wearers do not feel tightness can be obtained. Moreover, the inventors of the present application have reached a conclusion that it is preferred that the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab be 34 through 38 [gf/cm2].
Furthermore, the inventors of the present application have reached a conclusion that it is preferred that the relationship among the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab, the wearing pressure, when the garment is worn, at sections in the filler clothes 3 other than the intersecting part 3ab, and the wearing pressure, when the garment is worn, at sections other than the filler clothes 3 (main body portion 2) be expressed as “the wearing pressure, when the garment is worn, at the intersecting part>the wearing pressure, when the garment is worn, at the sections in the filler clothes 3 other than the intersecting part>the wearing pressure, when the garment is worn, at the sections other than the filler clothes 3 (main body portion 2). Specifically, the inventors of the present application have reached a conclusion that it is preferred that the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab be 30 through 60 [gf/cm2], the wearing pressure, when the garment is worn, at the sections in the filler clothes 3 other than the intersecting part be 15 through 50 [gf/cm2], and the wearing pressure, when the garment is worn, at the sections in the filler clothes 3 other than the intersecting part be 0 through 30 [gf/cm2].
Next, the inventors of the present application created a sample in which the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab is 34.6 [gf/cm2]. Then, the pressures at eight peripheral regions around the intersecting part on this sample was measured. Here, the eight peripheral regions are explained with reference to
As a result of the abovementioned measurement, the wearing pressure, when the garment is worn, at the region R1 is 9.5 [gf/cm2], the wearing pressure, when the garment is worn, at the upper right region R2 is 28.6 [gf/cm2], the wearing pressure, when the garment is worn, at the right region R3 is 14.4 [gf/cm2], the wearing pressure, when the garment is worn, at the lower right region R4 is 22.8 [gf/cm2], the wearing pressure, when the garment is worn, at the lower region R5 is 11.7 [gf/cm2], the wearing pressure, when the garment is worn, at the lower left region R6 is 26.9 [gf/cm2], the wearing pressure, when the garment is worn, at the left region R7 is 17.8 [gf/cm2], and the wearing pressure, when the garment is worn, at the upper left region R8 is 25.3 [gf/cm2]. Further, the wearing pressure, when the garment is worn, on the back of the thigh where the filler clothes 3 are not formed was 18.1 [gf/cm2].
Of the pressures at the peripheral regions R1 through R8, the minimum value is 9.5 [gf/cm2] at the upper region R1, and the maximum value is 28.6 [gf/cm2] at the upper right region R2. Therefore, it is understood that the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab is approximately 1.2 through 3.7 times the wearing pressures, when the garment is worn, at the peripheral regions R1 through R8.
Of the peripheral regions, the peripheral region in the filler clothes 3 are four peripheral regions of the upper right region R2, the lower right region R4, the lower left region R6, and the upper left region R8. Of the wearing pressures, when the garment is worn, at these four peripheral regions, the minimum value is 22.8 [gf/cm2] at the lower right region R4, and the maximum value is 28.6 [gf/cm2] at the upper right region R2. Therefore, it is understood that the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab is approximately 1.2 through 1.6 times the wearing pressures, when the garment is worn, at these four peripheral regions R2, R4, R6, and R8.
Of the peripheral regions, the peripheral regions in the sections other than in the filler clothes 3 are four peripheral regions of the upper region R1, the right region R3, the lower region R5, and the left region R7. Of the wearing pressures at these four peripheral regions, the minimum value is 9.5 [gf/cm2] at the upper region R1, and the maximum value is 17.8 [gf/cm2] at the left region R7. Therefore, it is understood that the wearing pressure at the filler cloth intersecting part 3ab is approximately 1.9 through 3.7 times the wearing pressures, when the garment is worn, at these four peripheral regions R1, R3, R5, and R7.
Further, since the wearing pressure, when the garment is worn, on the back of the thigh is 18.1 [gf/cm2], it is understood that the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab is approximately 1.9 times the wearing pressure, when the garment is worn, at the back of the thigh.
Next, the inventors of the present application created a sample obtained by removing the filler clothes besides the intersecting part 3ab from the sample in which the wearing pressure, when the garment is worn, at the filler cloth intersecting part 3ab is 34.6 [gf/cm2], i.e. a sample which does not have a cross structure. By removing the filler clothes besides the intersecting part 3ab from the sample having the cross structure, the pressure at the filler cloth part on the sample which does not have the cross structure has reduced to 28.7 [gf/cm2]. It can be considered that this is because the tension is hardly applied to the belly muscle of the rectus femoris muscle by removing the filler clothes other than the intersecting part 3ab. Accordingly, the pressure was reduced below 30 [gf/cm2] at which it is confirmed that effective advantages on the gluteus maximus muscle are obtained.
For such a sample which does not have the cross structure, the wearing pressures, when the garment is worn, at the eight peripheral regions around the filler cloth part on the sample which does not have the cross structure were measured, as with the case of the sample having the cross structure.
As a result of the measurement, the wearing pressure, when the garment is worn, at the upper region was 13.4 [gf/cm2], the wearing pressure, when the garment is worn, at the upper right region was 18.9 [gf/cm2], the wearing pressure, when the garment is worn, at the right region was 17.5 [gf/cm2], the wearing pressure, when the garment is worn, at the lower right region was 17.5 [gf/cm2], the wearing pressure, when the garment is worn, at the lower region was 16.9 [gf/cm2], the wearing pressure, when the garment is worn, at the lower left region was 18.6 [gf/cm2], the wearing pressure, when the garment is worn, at the left region was 17.2 [gf/cm2], and the wearing pressure, when the garment is worn, at the upper left region was 21.9 [gf/cm2]. Moreover, the wearing pressure, when the garment is worn, at the back of the thigh where the filler clothes 3 are not formed was 17.5 [gf/cm2].
Of the pressures at these peripheral regions, the minimum value is 13.4 [gf/cm2] at the upper region, and the maximum value is 21.9 [gf/cm2] at the upper left region. Therefore, it is understood that the wearing pressure, when the garment is worn, at the filler cloth part is approximately 1.3 through 2.2 times the wearing pressures, when the garment is worn, at the peripheral regions.
Further, since the wearing pressure, when the garment is worn, on the back of the thigh is 17.5 [gf/cm2], it is understood that the wearing pressure, when the garment is worn, at the filler cloth part is approximately 1.6 times the wearing pressure, when the garment is worn, at the back of the thigh.
Here, the widths and shapes of the filler clothes 3 are explained with reference to
Next,
There were specific example answers of the wearers, such as “buttocks became firm and tight” (four out of ten), “jeans fits smoothly” (three out of ten), “a space is created between thighs” and the like.
When the shapes of the buttocks of the testers were actually measured before and after the period of the trial, it was confirmed in eight out of the ten testers that the shape of their buttocks have changed. Out of the testers whose shapes of the buttocks have changed, for those testers who used to have slack buttocks, it was confirmed that their buttocks have risen, and for those testers whose buttocks were not slack before, it was confirmed that from the gluteal fold to thighs become lean. It should be noted that for two testers from which no changes in the shapes of their buttocks were observed, it was confirmed that they took only 5000 steps a day. According to the national nutrition survey, the average number of steps is 8200 for men and 7300 for women. Therefore, since these two testers from which no changes in the shapes of their buttocks were observed did not have much time to wear the sample and walk, it is considered that the shape of their buttocks have not changed. Other monitors different from these ten monitors were allowed to wear a girdle without the filler clothes for one month, but the shape of their buttocks did not change.
It should be noted in the above embodiment that the filler clothes formed on the bottom garment 1 were formed in an “x” shape when viewed from the front, but the shape of the filler clothes is not limited to the shape of an “x”. For example, the shape of the filler clothes may be the shape of a “+”. In other words, it is preferred that the filler clothes intersecting with each other and that the middle point between the interspinal point and patellar midpoint be positioned in the intersecting part.
Furthermore, in the above embodiment, the two strip-shaped filler clothes 3a and 3b (tightening portions) were formed so that the filler clothes intersect with each other, but a filler cloth out of the filler clothes, which is formed besides the intersecting part 3ab, may be removed so that only the intersecting part 3ab is formed. In this case, preferably the filler clothes and the main body portion are configured such that the wearing pressure, when the garment is worn, at the filler clothes is at least 30 [gf/cm2], the wearing pressure, when the garment is worn, at sections other than the filler clothes (main body portion) is 30 [gf/cm2] or less, and the differential wearing pressure, when the garment is worn, between the pressure at the filler clothes and the wearing pressure, when the garment is worn, at the sections other than the filler clothes is at least 10 [gf/cm2]. Accordingly, the quadriceps can be stimulated without giving a tight feeling to the wearers, thus a bottom garment in which the gluteus maximus muscle can be used and which does not provide a feeling of tightness to the wearer can be provided.
Moreover, in the above embodiment, the tightening portions are formed by using the filler clothes on the bottom garment 1, but the clothes to be used for forming the tightening portions are not limited to the filler clothes. For example, a dart may be used. Further, the main body portion and the tightening portion may be switched by power switching of warp knitting or circular knitting (circular knitting). Further, a bone or polyurethane resin may be added to a cloth corresponding to the tightening portion to add a strong tightening force to the cloth.
It is preferred that a highly elastic material be used for a crotch section of the bottom garment in the above embodiment. This is performed so that a movement of increasing the length of stride is not obstructed, since the length of stride increases when walking in the bottom garment of the embodiment.
Moreover, the above embodiment describes the girdle as the bottom garment, but the present invention can be applied to a garment other than the girdle. For example, the present invention can be applied to a bottom garment such as a pair of spats, men's spats, stockings, tights, supporters, and a suspender belt.
The basic configuration of the present invention is a point that, in the bottom garment, the tightening portions are provided at the front section of a thigh, i.e. the section corresponding to the middle point between the interspinal point and the patellar midpoint, whereby the quadriceps can be stimulated and the movement of the quadriceps is not obstructed. Accordingly, the wearer can kick his legs backward significantly in a natural fashion so that the gluteus maximus muscle is used. Therefore, only by walking in the bottom garment of the present invention, natural tight buttocks can be realized. With such a configuration, various embodiments in addition to the above embodiment can be realized. For example, the tightening portions may be formed into shapes other than the shapes of the filler clothes of the embodiment.
