Description of the Invention

[0010] The sports bottom wear of the present invention includes a stretchable main cloth that covers an area spanning from the waist to at least above the knees. That is to say, the hem can be at any position from above the knees to the ankles. For example, the hem is above the knees, below the knees, at the shins, or at the ankles. This allows the bottom wear to be worn in different climates while maintaining high exercise performance of the thighs. This bottom wear is worn substantially in tight contact with the body. To keep the bottom wear substantially in tight contact with the body, the portion extending around the waist is preferably 70 to 80% of the standard size of the human body. The body length direction is preferably set to be almost the same as that of the body.

[0011] The sports bottom wear of the present invention includes strongly tightened parts A disposed in regions of a front portion of the main cloth that lie below a line extending in the lateral direction from a crotch portion of the front portion and above the knees, and strongly tightened parts B disposed in regions along the medial compartments of the thighs. The strongly tightened parts A are preferably in regions that cover at least the center areas of the rectus femoris muscles. Furthermore, the strongly tightened parts B in the regions along the medial compartments of the thighs are preferably located in regions that cover the adductor muscle groups. The muscles in these areas are likely to shake and the shaking is slow to subside, and thus the strongly tightened parts A and B covering these muscle areas can suppress muscle vibration.

[0012] It is preferable that the strongly tightened parts A and B are each constituted by at least one selected from a cloth piece of the main cloth and a cloth piece different from the main cloth, and bonded to at least one selected from back and front faces of the main cloth by means of an adhesive. This reduces the number of sewing lines and leaves unnecessary portions as the main cloth as is, thereby providing good wearing comfort. The cloth piece different from the main cloth may have the same or different tightness as that of the main cloth. If the different cloth piece is not as tight as the main cloth, the tightness may be lower or higher than that of the main cloth. The tightness is preferably the same as or higher than that of the main cloth. The strongly tightened parts A and B are preferably disposed independently of each other. Moreover, methods other than bonding the cloth pieces, such as partially changing the weave or partially melting yarns that melt upon heating, may be used to form the strongly tightened parts.

[0013] It is preferable that the main cloth of the sports bottom wear of the present invention includes a right cloth, a left cloth, and a band-shaped cloth, the right cloth and the left cloth are connected to each other along a front-back center line to form a body portion, and the right cloth and the left cloth are connected to each other via the band-shaped cloth to form medial thigh portions. The absence of sewing lines in the body length direction in the side portions is for better wearing comfort. The band-shaped cloth is interposed in the medial thigh portions in order to bond the cloth pieces to regions of the band-shaped cloth to from strongly tightened parts.

[0014] It is preferable that the adhesive for bonding the cloth pieces is a hot-melt adhesive applied in a dot pattern or partially. For example, the hot-melt adhesive can be applied in a dot pattern or partially through screen printing. It is preferable that the applied adhesive has a porosity of approximately 10 to 30% and preferably approximately 15 to 25% in a plan view, because air permeability and adhesiveness are satisfied and the adhesive is unlikely to peel off. The reason for the resistance to peeling is that when stress is applied, the main cloth and the cloth pieces absorb the stress.

[0015] It is preferable that the main cloth is a two-way knitted fabric, and has a load at 10% stretch of preferably 0.3 to 3 N in the vertical direction and 0.2 to 1 N in the horizontal direction, for example. If the load is within this range, excellent wearing comfort is provided. Furthermore, in case of strenuous exercise, the stretching properties are insufficient unless the main cloth is a knitted fabric. The cloth pieces (cloths for bonding) have a load at 10% stretch of preferably 3 to 10 N in the vertical direction and 2 to 10 N in the horizontal direction. The strongly tightened parts obtained by bonding the main cloth and the cloth pieces (cloths for bonding) to each other have a load at 10% stretch of preferably 10 to 35 N in the vertical direction and 10 to 30 N in the horizontal direction. If the load is within this range, muscle vibration is effectively suppressed. The load at 10% stretch is preferably main cloth < cloth piece (cloth for bonding) < strongly tightened part in both the vertical and horizontal directions.

[0016] The main cloth has air permeability according to the JIS L 1096 Frazier air permeability test of preferably 50 to 250 cm 3< / cm 2< ·s, and more preferably 70 to 150 cm 3< / cm 2< ·s. The strongly tightened parts have air permeability according to the same of preferably 0.5 to 10 cm 3< / cm 2< ·s, and more preferably 1 to 8 cm 3< / cm 2< ·s. With such air permeability, good wearing comfort can be maintained. Furthermore, since the portions in which the strongly tightened parts are disposed are areas where muscles are used frequently, lowering the air permeability in those areas can make them less susceptible to cooling, thereby suppressing a decrease in the athletic performance during cold weather.

[0017] According to the invention a strongly tightened part C is further provided at a position overlapping an area around the pelvis, that is, around the hips so as to maintain anterior pelvic tilt, with a central width of a back portion being greater than that of a front portion of the strongly tightened part C, and the top of the back portion being higher than that of the front portion. The strongly tightened part C allows the pelvis to tilt forward and maintain a posture suitable for running.

[0018] It is preferable that strongly tightened parts D are provided at positions overlapping the vastus lateralis muscles. The strongly tightened parts D allow the thighs to maintain a higher level of athletic performance. The combination of the strongly tightened parts A disposed in the vicinity of the quadriceps femoris muscles and the strongly tightened parts D can suppress the thighs from being swept rearward during running.

[0019] The cloths for bonding in the sports bottom wear of the present invention may be disposed such that the tightening pressure varies in a stepwise manner in the strongly tightened parts A to D. The arrangement of the cloths for bonding in which the tightening pressure varies in a stepwise manner can be controlled by changing the density of the adhesive per area, that is, by changing the porosity. As an example, the tightening pressure may vary in the strongly tightened parts such that A> B > C > D, or may vary in each strongly tightened part.

[0020] The main cloth and the cloths for bonding each have a mass (basis weight) per unit area of preferably 40 to 200 g / m 2< , and more preferably 110 to 130 g / m 2< . If the basis weight is within this range, the garment is lightweight and suitable for use as sports bottom wear.

[0021] Hereinafter, the present invention will be described with reference to the drawings. In the drawings below, the same reference numerals denote the same constituent elements. FIG. 1A is a front view of sports bottom wear 1 according to an example of the present invention, FIG. 1B is a rear view thereof, and FIG. 1C is a side view thereof. A main cloth of the sports bottom wear 1 includes a right main cloth 2a, a left main cloth 2b, and a band-shaped main cloth 2c. The right main cloth 2a and the left main cloth 2b are connected to each other along a front-back center line to form a body portion, and the right main cloth 2a and the left main cloth 2b are connected to each other via the band-shaped main cloth 2c to form medial thigh portions. There are no sewing lines in the body length direction of the side portions. Strongly tightened parts A (4a and 4b) are disposed in regions of a front portion of the main cloth (2a, 2b, and 2c) that lie below a line extending in the lateral direction from a crotch portion 3 of the front portion and above the knees, and strongly tightened parts B (5a and 5b) are disposed in regions along the medial compartments of the thighs. The strongly tightened parts A and B are constituted by cloth pieces (cloths for bonding) that are tighter than the main cloth and bonded to a back face or a front face of the main cloth by means of an adhesive. Preferably, the cloth pieces (cloths for bonding) are bonded to the back face of the main cloth by means of an adhesive. A belt portion 7 is formed at the upper end of the main cloth and a string 8 is passed through the belt portion to secure the main cloth to the torso of the body.

[0022] The strongly tightened parts A (4a and 4b) of the large size as defined by the size standards established by the Association of Japan Sporting Goods Industries (JASPO) are preferably positioned as follows. (1) The upper limit is at a distance downward from the line extending in the lateral direction from the crotch portion 3 by L1: 30 to 70 mm and preferably 40 to 60 mm. (2) The lower limit is at a distance downward from the line extending in the lateral direction from the crotch portion 3 by L2: 150 to 190 mm and preferably 160 to 180 mm. (3) The boundary on the medial side is at a distance from the medial edge of the bottom wear as seen from the front by L3: 5 to 25 mm and preferably 10 to 20 mm. (4) The boundary on the lateral side is at a distance from the lateral edge of the bottom wear as seen from the front by L4: 35 to 65 mm and preferably 45 to 55 mm. (5) The strongly tightened parts A (4a and 4b) described above preferably each have a trapezoidal shape that is longer on the medial thigh side and is shorter on the lateral thigh side or a rectangular shape similar thereto (the shape having rounded corners). The strongly tightened parts more preferably each have a trapezoidal shape.

[0023] The strongly tightened parts B (5a and 5b) are preferably located at positions along the medial compartments of the thighs respectively corresponding to the medial sides of the strongly tightened parts A (4a and 4b), and preferably each have a length that is the same as that of the medial side of the strongly tightened parts A (4a and 4b) or within ±3 cm of the corresponding medial side. If the length exceeds this range, the bottom wear makes it difficult for the wearer to open his or her legs, and tends to interfere with athletic movements. The strongly tightened parts B preferably each have a parallelogram shape or a rectangular shape similar thereto (the shape having rounded corners).

[0024] As shown in FIGS. 1A to 1C, the strongly tightened part C (6) is, according to the invention, disposed at a position overlapping an area around the pelvis, so as to maintain pelvic tilt forward, with a central width L6 of a back portion being greater than a central width L5 of a front portion of the strongly tightened part C, and the top of the back portion being higher than that of the front portion.

[0025] FIG. 2A is a front view of sports bottom wear 10 according to another example of the present invention, and FIG. 2B is a rear view thereof. This example is different from the sports bottom wear 1 shown in FIGS. 1A to 1C, in that cloth pieces are bonded to regions that cover lateral compartments of the thighs (the vastus lateralis muscles) as well to form strongly tightened parts D (9a, 9b, 9c, and 9d). This enables suppression of muscle vibration of the lateral compartments of the thighs (the vastus lateralis muscles). The strongly tightened parts D (9a, 9b, 9c, and 9d) are preferably formed so as to be inclined downward to the outer side at an angle of 10 to 45°.

[0026] FIG. 3Ais a front view of sports bottom wear 11 according to another example of the present invention, and FIG. 3B is a rear view thereof. This example is different from the sports bottom wear 1 shown in FIGS. 1A to 1C, in that cloth pieces are bonded to regions that cover posterior compartments of the thighs (the hamstrings) as well as forming strongly tightened parts E (12a and 12b). This is expected to suppress muscle vibration better than the aforementioned sports bottom wear 1. Since bonding of cloths to regions in which skin stretches considerably during hip flexion is avoided and support lines 13 are formed spirally as a whole, it is also possible to expect the suppression of external rotation of the hip joint (internal rotation support, preventing the bowing of legs) without causing discomfort when lifting the legs.

[0027] FIG. 4Ais a front view showing leg muscle areas that are likely to shake, according to an embodiment of the present invention, FIG. 4B is a right side view thereof, FIG. 4C is a rear view thereof, and FIG. 4D is a left side view thereof. The darker dots indicate areas of the body in which muscles are more likely to shake. The circled areas indicate areas of the body in which muscles are highly likely to shake.

[0028] FIG. 5A is a front view showing leg muscle areas where shaking is slow to subside, according to an embodiment of the present invention, FIG. 5B is a right side view thereof, FIG. 5C is a rear view thereof, and FIG. 5D is a left side view thereof. The lighter dots indicate areas of the body in which shaking of muscles is slower to subside. The circled areas indicate areas of the body in which shaking of muscles is significantly slow to subside.

[0029] The areas where leg muscles are likely to shake and the areas where shaking is likely to subside can be measured using the following method, for example.

[0030] First, with an accelerometer (1-axis) attached to a total of 48 points (24 points on the right thigh and 24 points on the right lower thigh), the subject is made to maintain his or her posture with the left leg and arms placed on a stepladder such that the right leg is sufficiently relaxed. Next, an acceleration response is measured by striking the vicinity of the distal 2 cm of the accelerometer with an impulse hammer. This measurement is performed 5 times for each site. The measured acceleration is low-pass filtered at 100 Hz and noise processed. The input peak (F; kgf) and acceleration peak (a; m / s 2< ) are then calculated. This acceleration peak is divided by the input peak to obtain the inertance of the muscle (inertance = a / F) as a transfer function. The higher the inertance, the more likely the muscle is to shake, and the lower the inertance, the less likely the muscle is to shake. The logarithmic decrement (δ = ln(1 st< Peak / 2 nd< Peak)) is obtained from the decrement of the largest peak and the decrement of the second largest peak that appear after input. The lower the logarithmic decrement, the slower the shaking of muscles is to subside, and the higher lower the logarithmic decrement, the more rapidly the shaking of muscles is to subside.

[0031] The sports bottom wear 1 shown in FIGS. 1A to 1C includes cloth pieces that are bonded to the back face of the main cloth so as to cover the circled areas shown in FIG. 4A and 4B and FIG. 5A and 5B, that is, the areas where muscles are likely to shake and the shaking is slow to subside to form the strongly tightened parts A and B.

[0032] FIG. 6A is a front view showing human skin areas where stretching is considerable during running, according to an embodiment of the present invention, and FIG. 6B is a rear view thereof. The darker dots indicate areas where the skin stretches more considerably.

[0033] FIG. 7A is a front view showing human skin areas where shrinking is considerable during running, according to an embodiment of the present invention, and FIG. 7B is a rear view thereof. The lighter dots indicate areas where the skin shrinks more considerably.

[0034] The areas where the skin stretches considerably and the areas where the skin shrinks considerably can be calculated by generating a 3D CG model of the body from body segment information during movement. Specifically, the method described in Japanese Patent No. 3831348 can be applied.

[0035] In the present invention, the strongly tightened parts A and B are provided so as to avoid the areas where the skin stretches considerably and the areas where the skin shrinks considerably, in order to improve the wearing comfort.

[0036] FIG. 8Ais a front view of a hot-melt adhesive printed design sheet according to an embodiment of the present invention, and FIG. 8B is an enlarged view thereof. This example shows an adhesive printed design sheet in the shape of Y letters combined, each of which has a length L7 of 20 mm and a width L8 of 25 mm as shown in FIG. 6B. The application rate is 82% and the porosity is 18%. This has the advantage of satisfying both air permeability and adhesiveness, as well as being unlikely to peel off. The reason for the resistance to peeling is that when stress is applied, the main cloth and the cloth pieces absorb the stress. This hot-melt adhesive printed design sheet has isotropic stretchability.Examples

[0037] Hereinafter, the present invention will be described in further detail by way of examples. Note that the invention is not to be interpreted as being limited to the following examples.Example 1

[0038] The main cloth used was a two-way knitted fabric (with a mass of 190 g / m 2< ) using, as knitting yarns, a covering yarn with a polyurethane elastic yarn serving as a core and a nylon multifilament yarn wound therearound to coat the core.

[0039] The cloth piece (cloth for bonding) was a two-way woven fabric (with a mass of 120 g / m 2< ) using, as warp and weft yarns, a covering yarn with a polyurethane elastic yarn serving as a core and a nylon multifilament yarn wound therearound to coat the core. This cloth piece (cloth for bonding) is the hot-melt adhesive printed design sheet shown in FIG. 8.

[0040] The cloth piece (cloth for bonding) was cut to have a predetermined shape and bonded to the main cloth through heating and pressurizing at 175°C for 30 seconds. The loads at 10% stretch of the main cloth, the cloth piece (cloth for bonding), and the strongly tightened part are as shown in Table 1 and FIGS. 15 and 16. Table 1Load at 10% stretch (N)Main clothVertical1.03Horizontal0.55Cloth piece (Cloth for bonding)Vertical4.98Horizontal4.32Strongly tightened partVertical26.12Horizontal20.86

[0041] The pieces of sports bottom wear 1 shown in FIGS. 1A to 1C were produced using the main cloth including the strongly tightened parts A and B described above. The strongly tightened parts A each had a rectangular shape similar to a trapezoidal shape (with rounded corners), and were parts of the large size (JASPO) positioned as follows. (1) The upper limit was at a distance downward from the line extending in the lateral direction from the crotch portion 3 by L1: 50 mm. (2) The lower limit was at a distance downward from the line extending in the lateral direction from the crotch portion 3 by L2: 173 mm. (3) The boundary on the medial side was at a distance from the medial edge of the bottom wear as seen from the front by L3: 15 mm. (4) The boundary on the lateral side was at a distance from the lateral edge of the bottom wear as seen from the front by L4: 50 mm. (5) The side on the medial thigh side had a length of 125 mm, the side on the lateral thigh side had a length of 55 mm, the upper side had a width of 102 mm, and the lower side had a width of 95 mm. The strongly tightened parts B each had a rectangular shape similar to a parallelogram shape (with rounded corners), in which the longer sides each had a length of 125 mm, the upper side had a width of 45 mm, and the lower side had a width of 35 mm.

[0042] The main cloth had air permeability according to the JIS L 1096 Frazier air permeability test of 123 cm 3< / cm 2< ·s, and the strongly tightened parts A and B each had air permeability according to the same of 3.29 cm 3< / cm 2< ·s.

[0043] The overall dimensions of the thus obtained sports bottom wear 1 of the large size (JASPO) were 420 mm in length, 325 mm in hip width, and 115 g in weight in the static state. The size was formed to be 75% of the portion extending around the waist and 65% of the portion extending around a thigh compared with the standard size of the human body of the large size (JASPO).Comparative Example 1

[0044] Half tights made of a commercially available cloth without support functions were used as Comparative Example 1.

[0045] The sports bottom wear 1 obtained in Example 1 and the half tights made of a commercially available cloth without support functions were subjected to a wearing test. Wearing test conditions were as follows. Subject: Male in his 20s Measurements: EMG and acceleration were measured at the rectus femoris, adductor magnus muscle, and long head of the biceps femoris muscle. Sequence: Running on a treadmill at 14 km / h for 5 minutes to warm up, 20 minutes of rest, running at 14 km / h for 10 minutes wearing the half pants of Comparative Example 1, 20 minutes of rest, and running at 14 km / h for 10 minutes wearing the pants of Example 1. Results: As shown in Table 2 below and FIGS. 9 and 10, the pants of Example 1 suppressed muscle vibration (FIG. 9), and reduced muscle activity (FIG. 10). Table 2 Average acceleration (%)Muscle activity rate (%)Ex. 1Com.Ex. 1Ex. 1Com.Ex. 1Rectus femoris muscle90.7910089.18100Adductor magnus muscle89.1210097.09100Biceps femoris muscle94.7910065.46100 Comparative Example 2

[0046] Half pants of Patent Document 4 above were used as Comparative Example 2. FIG. 11A is a front view of the half pants of Patent Document 4, FIG. 11B is a right side view thereof, and FIG. 11C is a rear view thereof. The half pants include a strongly tightened part extending around the hips which is formed through sewing.

[0047] FIG. 12 is a graph showing the load-stretch ratio of the pants cloth of Example 1 (bonding specification) and the pants cloth of Comparative Example 2 (sewing specification). It is clearly seen from FIG. 12 that the pants cloth of Example 1 (bonding specification) stretches considerably. The advantage of stretching well is that the pants are comfortable to wear and do not interfere with athletic movements.Examples 2 and 3 and Comparative Examples 3 and 4

[0048] Half pants shown in FIGS. 2A and 2B were used as Example 2. The cloth and the cloth piece (cloth for bonding) used were the same cloth and hot-melt adhesive printed design sheet as those of Example 1.

[0049] Half pants shown in FIGS. 3A and 3B were used as Example 3. The cloth and the cloth piece (cloth for bonding) used were the same cloth and hot-melt adhesive printed design sheet as those of Example 1.

[0050] Commercially available half tights with support functions were used as Comparative Example 3.

[0051] Pants (half pants) shown in FIG. 1 of Patent Document 3 above were used as Comparative Example 4.

[0052] These half pants were worn and the garment pressure was measured at the positions shown in FIGS. 13A to 13C. The garment pressure was measured using a garment pressure measuring device (product name "Contact Surface Pressure Sensor AMI3032-2 (2B)" manufactured by AMI Techno Co., Ltd.).

[0053] The garment pressure measurement positions were as follows. 14: Inferior anterior compartment of thigh 15: Superior anterior compartment of thigh 16: Medial compartment of thigh 17: Lateral compartment of thigh 18: Posterior compartment of thigh

[0054] Table 3 and FIG. 14 show the garment pressure at each of the measurement positions in the half pants of Examples 1 to 3 and Comparative Examples 3 and 4. The unit of mV for garment pressure is 100 mV = 1 kPa = 10 hPa. Table 3Garment pressure (mV)Inferior anterior compartment of thighSuperior anterior compartment of thighLateral compartment of thighMedial compartment of thighPosterior compartment of thighEx. 13396179165152Ex. 220856112110133Ex. 3494122187289331Com.Ex. 3211147163131180Com.Ex. 417094151135245

[0055] As is clear from Table 3 and FIG. 14, a comparison between the garment pressures at the inferior anterior compartment of the thigh and the superior anterior compartment of the thigh showed that Example 1 had 5.6 times the garment pressure, Example 2 had 3.7 times the garment pressure, and Example 3 had 4.0 times the garment pressure. On the other hand, Comparative Example 3 had 1.4 times the garment pressure and Comparative Example 4 had 1.8 times the garment pressure, indicating the superiority of Examples 1 to 3.

[0056] Also, a comparison between the garment pressures at the medial compartment of the thigh and the lateral compartment of the thigh according to Examples 1 to 3 showed that the garment pressures were almost the same or higher, and were superior to the garment pressures at the medial compartment of the thigh and the lateral compartment of the thigh according to Comparative Examples 3 and 4.Example 4

[0057] The same cloth piece (woven fabric) as that of Example 1 was used as a cloth piece to be bonded to form a strongly tightened part in Example 2, a hot-melt adhesive sheet was laminated on one side thereof, and this cloth piece was attached to the cloth of the half pants. Table 4 shows the garment pressure at each of the anterior compartment of the thigh, the medial compartment of the thigh, and the abdomen.Example 5

[0058] The same knitted piece (knitted fabric) as the main cloth was used as a cloth piece to be bonded to form a strongly tightened part in Example 2, a hot-melt adhesive sheet was laminated on one side thereof, and this cloth piece was attached to the cloth of the half pants. Table 4 shows the garment pressure at each of the anterior compartment of the thigh, the medial compartment of the thigh, and the abdomen.

[0059] As is clear from Table 4, it is preferable that the cloth piece to be bonded to form a strongly tightened part has the same (Example 5) or higher (Example 4) tightness than the main cloth. The reason why the garment pressure at these points is higher in Example 5 than in Example 4 is that the knitted piece (knitted fabric) of cloth is thicker than the woven fabric cloth.Industrial Applicability
