Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower garment having a clothing pressure suitable for exercise, in which the variation of the clothing pressure with leg exercise is small and the resistance to leg exercise is reduced. The purpose of this is to provide a lower garment with high performance.

[0002]

2. Description of the Related Art Conventionally, various cutting methods and sewing methods have been disclosed in order to provide a lower garment suitable for exercise and not to hinder leg movement during exercise. However, these conventional methods have a problem that the pattern is complicated and a large number of members must be sewn due to the pursuit of functionality. In addition, there have been few designs that have conventionally been made by incorporating human anatomy and biomechanical knowledge into those designs, and many have relied on empirical rules and individual intuition.

For example, in Japanese Utility Model Publication No. 39-25528,
Cut the leg cylinder from the knitted fabric knitted in a cylindrical shape,
Although the exercise tights without a gusset between the integrated crotch are disclosed, in the present invention, the angle of the corners that form the part from the inner crotch to the buttocks is cut because of cutting the left and right bodies from the cylindrical knitted fabric. There was a problem that it could not be adjusted. In Japanese Utility Model Publication No. 49-43461, ski trousers having improved athletic performance formed by stitching both legs, hips and crotch are disclosed in Japanese Utility Model Publication Nos. 50-44246 and 50-44.
No. 247 uses stretchable cloth and non-stretchable cloth in place,
The lower garment that prevents tightness is also the actual Kokomi Sho 52-4178.
The front piece, the back piece and the waist darts are integrally sewn on the No. 2 trousers to prevent twitches. Therefore, the lower garment which is adaptable to the movement form of the lower body is disclosed. However, the lower garment disclosed in these devices has many constituent members, and many of them are used for adjusting the clothing pressure. The parts had to be modified, and the sewing process was complicated.

[0004]

Therefore, the lower garment according to the present invention is a lower garment mainly suitable for exercise, and is designed in accordance with the structure of the human body, without impairing the wearer's motor function. It is an object of the present invention to provide a lower garment that can cope with intense exercise and that can be comfortably worn and that is adapted to the optimum clothing pressure. Furthermore,
It is an object of the present invention to provide a lower garment which achieves the above object and facilitates the adjustment of the clothing pressure by shortening the manufacturing process and improving the productivity by configuring with a small number of members and a simple structure.

Therefore, in the present invention, in order to study the characteristics of the clothing in terms of human anatomy and biomechanics, the skin of the human body is peeled off, the direction of development, which is the characteristic of the skin, is studied, and the clothing is based on that. When a wearer is worn, the site where the tightness and wrinkles are likely to occur is specified, and the optimal clothing pressure at the site is determined from the results of the sensory test obtained from a large number of subjects, and a lower garment that realizes that is provided.

[0006]

As a premise of the present invention, it is necessary to specify a region where a garment or a wrinkle is likely to occur when a lower garment is worn. When the skin of the lower body of the human body is regarded as a lower garment that is made of elastic fabric and adheres to the lower body, the direction of the wrinkles appearing on the surface and the density of the wrinkles are observed to determine the direction in which the lower garment should extend. The part to be extended can be specified. Therefore, as shown in FIG. 3, the skin from the waist line of the corpse to the knee head was peeled off along the structural line of the undergarment, and the direction of wrinkles on the skin surface was investigated.
As a result of this investigation, it was found that the skin stretched in the direction indicated by the arrow in the figure, that is, in the direction substantially perpendicular to the wrinkles. In addition, observing the density of wrinkles, it was found that many wrinkles were continuously concentrated near the waistline, near the center of the large buttocks, and along the line from the gluteal groove to the inner crotch to the kneecap. Especially in the vicinity of the buttocks, wrinkles connecting from the large buttocks,
A region where wrinkles connecting the inside and outside of the thigh intersected with each other was observed, and it was found that this region undergoes strong extension during leg movement.

As a result, even in the actual lower garment, a strong extension is exerted on the line from the waist line to the center of the buttocks and on the line from the gluteal groove to the kneecap via the inner crotch (hereinafter referred to as "twitch line"). It is believed that the fabric that makes up the batter is unable to adapt to its extension, resulting in tightness and pressure. Therefore, when designing a lower garment suitable for exercise, it is important that the suture line does not intersect with the pull line that requires the most extensibility. Also, the smaller the change in clothing pressure near the twitch line during the previous period of exercise, the more comfortable the undergarment is with less tightness and tightness.

[0008] Therefore, several kinds of underwear actually made of stretchable cloth, which are created by using a conventional pattern, are prepared, and a sensory test is conducted by using a large number of subjects for feeling of tightness and tightness. While performing, the clothing pressure near the buttocks was measured to determine the optimal clothing pressure. As a result, as shown in FIG. 4, when the clothing pressure at the F point near the gluteal groove when standing and resting was 10 to 30 g / cm ² , a tightness and a feeling of tightness were not felt, and an appropriate feeling of adhesion was obtained. It turned out that there were many test subjects.

From the above, the lower garment according to the present invention is a lower garment made of a stretchable fabric and has a corner portion so as not to provide a suture line intersecting with the drawstring line, and an optimal clothing is obtained. In order to achieve a pressure of 10 to 30 g / cm ² , the angle of the corners, that is, the line that is orthogonal to the front centerline in the half-body development view and that extends through the crotch point, The angle between the tangents is 110 to 130
It has a configuration in which both the left and right body parts that are inclined within a range of degrees are stitched together.

Further, in the lower garment according to the present invention, in order to simplify the work process at the time of manufacturing to increase the production efficiency and facilitate fine adjustment of the clothing pressure, each of the body parts has one rear suture line. A lower garment characterized by being sewn by.

[0011]

The lower garment according to the present invention is made of elastic cloth, and the angle formed by the tangent line of the rear crotch line to the crotch line which is orthogonal to the front centerline in the half body development view is 110 degrees to 130 degrees. A lower garment having a configuration having angled corners in a range of degrees, wherein the lower garment has a configuration having a corner along the line of pulling and sewing without providing a suture line intersecting with the line of pulling. Therefore, the extension of the lower garment on the tie line is not hindered. Also,
Since the angle can be freely adjusted within the range of 110 to 130 degrees, the clothing pressure on the twitch line can be easily adjusted. Furthermore, when the wearer wears the lower garment according to the present invention and exercises, it is possible to suppress a rise in clothing pressure in the process from the standing state to the state in which the legs are raised, and the leg movement during the exercise is inhibited. Never be done.

Further, since both body parts of the lower garment according to the present invention are sewn with a stretchable thread by one suture line on the rear part respectively, from the rear part of the waist line through the buttocks to the inner crotch part. Since it is possible to sew on the pull line extending to the kneecap without providing a suture line, the extension of the portion most strongly subjected to the extension action is not hindered. Further, since it is sewn with one suture line, when finely adjusting the clothing pressure, it is possible to perform fine adjustment by changing only the shape of the suture line. Further, since the inner crotch portion is not provided with the suture line, the resistance associated with the leg movement is extremely small, and it is possible to eliminate the problem of wear of the inner crotch portion suture line, which has been a problem in the past.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a lower garment according to the present invention will be described with reference to the drawings. FIG. 1 is a half-body development view of a lower garment according to the present invention. The lower garment according to the present invention uses a cloth having elasticity in both the vertical and horizontal directions such as a two-weight licotte, and the expansion rate is 100 to 130 in the vertical direction when 1 kg is loaded.
%, A fabric having a lateral direction of 80 to 120% is suitable.

As shown in FIG. 1, the lower garment according to the present invention comprises a half body composed of a body portion 1 and a corner portion 2 which are sewn on the left and right sides. The corner portion 2 has a waistline W1 and a rear crotch line M extending from one end of the waistline W1 to the crotch point cp.
1. The waistline W1 is surrounded by a waist suture portion a1 and a hip suture portion b1 extending downward from the other end of the waistline W1.
The corner portion 2 is extended at a predetermined angle, and the angle is a straight line from the waist line W2 to the ankle line B in the half body developed view and is orthogonal to the front center line X passing through the kneecap point kp. Which is a line, and the crotch line Y passing through the crotch point cp,
The angle θ formed by the tangent line Z of the rear crotch line M1 of the corner portion 2 is
Although it is defined in the range of 110 degrees to 130 degrees, by adjusting the angle θ, it is possible to change the clothing pressure of the portion from the buttocks to the twitch line L. Further, as shown in FIG. 5, the change in the clothing pressure of the lower garment according to the present invention during the process from the standing position to the raised state is smaller than that of the conventional lower garment, and the leg during exercise is reduced. It can be seen that the increase in clothing pressure that hinders exercise is reduced.

As shown in FIG. 2, in the lower garment according to the present invention, both body parts are sewn by one suture line. The suture line S1 of FIG. 1 is sewn with the suture line S2 to form a leg cylinder, and the left and right leg cylinders are integrally sewn together by the rear crotch line M1 and the front crotch line M2 to form a lower garment.
Since each body has one suture line, when adjusting the clothing pressure of the lower garment, the clothing pressure can be adjusted by simply changing the shape of the suture lines S1 and S2 while keeping the angle θ of the corner portion 2 unchanged. Can be adjusted, which is extremely advantageous in the manufacturing process.

Athletes have different muscle parts depending on the sporting event, and if the clothing pressure is finely adjusted according to the developed muscle parts, a more suitable undergarment can be provided. For example, in the case of a skater who has developed muscles from the buttocks to the thighs, buttocks sutures b1 and b2
And the thigh sutures c1 and c2 should be brought out. When it is desired to make the legs look beautiful like a gymnast, the buttocks suture b1
And b2 to the lower leg suture portions e1 and e2 may be stuffed together and sutured. As described above, since the lower garment according to the present invention is sewn by one suture line, only the shape of the suture line S can be changed to make fine adjustments according to the condition of muscle development and the characteristics of the competition. It is possible.

[0017]

Since the lower garment according to the present invention has the above-mentioned structure, it has the following effects. First, since the lower garment according to the present invention has a corner portion, it is possible to sew the thigh line requiring the most extensibility without the suture lines crossing each other, and extension of the leg flexion is hindered. The effect is that the wearer does not feel tight or tight. Furthermore, since there is no suture line on the inner crotch area, the resistance associated with leg movement is extremely low, and
It is possible to eliminate the problem of wear of the inner crotch suture line, which has been a problem in the past.

Further, the angle of the corner portion is 110 degrees to 13 degrees.
Since it is inclined in the range of 0 degree, the clothing pressure at the inner crotch point is limited to the range of 30 to 10 g / cm ² , and by adjusting the corner portion in the angle range, the Batteries can be provided. Also, the fifth
As shown in the figure, the difference between the clothing pressure at the inner crotch point when standing and resting and the clothing pressure at the inner crotch point when the wearer bends his legs can be kept small, so the clothing pressure at the time of standing and resting is low. It does not cause the lower garment to slip down, and on the contrary, it has the effect of suppressing the feeling of tightness and tightness due to the increase in clothing pressure during exercise, and not hindering the motor function.

Next, in the lower garment according to the present invention, both body parts are sewn by one suture line, so that when the clothing pressure of the lower garment is adjusted, the angle of the corner portion remains the same.
The clothing pressure can be adjusted simply by changing the shape of the suture line, which is extremely advantageous in the manufacturing process.

Athletes have different muscle regions that develop depending on the sporting event, and if the clothing pressure is finely adjusted according to the muscle developing region, a more suitable undergarment can be provided. Since the lower garment according to the present invention is sewn with a single suture line, it is possible to make fine adjustments according to muscle development simply by changing the shape of the suture line.
