DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underpatch having a waist support function at the time of exercise or the like by using a cloth knitted with elastic yarn for a waist.

[0002]

2. Description of the Related Art Conventionally, a fabric knitted with an elastic yarn has a width of 3 mm.
It is used as a substitute for waist rubber on the waist part of the lower part of the waist up to 4 cm, used as a belly band for keeping warm, or used as a lower part for women to make the waist look thin etc. ing.

[0003] However, the underpants conventionally provided are poor in the function of supporting the lower back during exercise or the like. On the other hand, there is a case where a lower back pain occurs after a full swing with a golf club or after performing various sports. There are various causes of low back pain, but the movement or twisting of the lower back may cause the lumbar spine to shift, which may be the cause. In order to prevent the lumbar spine from shifting, it is important to train the abdominal muscles and the back muscles, but it is said that wearing a corset or a wide belt for protecting the lumbar region is also effective.

[0004]

When playing golf or other sports, it is very troublesome to wear a corset or a wide belt every time, and it is too exaggerated or unsightly. It is considered that it is often not executed for some reason.

Therefore, the present inventor worked on research and development from the viewpoint that anyone could wear the underpants having the function of supporting the lower back, and completed the present invention. Things.

[0006]

In order to achieve the above-mentioned object, the present invention provides a method of fabricating an underpouch, comprising an upper part made of a knitted elastic yarn, a lower part made of a separate cloth, and a boundary between upper and lower parts.
The line should be slightly above the wearer's femoral head on both sides and
Consists of upwardly convex arcuate lines from the position on both sides,
Is constituted by a downwardly convex arcuate line from the positions on both sides, and the upper fabric covers the waist of the wearer and the vicinity of the lower part of the ischia closely.

[0007] With the above structure, the upper part of the underpouch made of the cloth knitted with the elastic yarn is in close contact with the wearer's waist due to the elastic contraction force of the cloth, thereby reliably supporting the waist. In addition, the protective action of the lumbar spine by the back muscles can be improved, and the elasticity of the elastic body does not hinder the wearer's movement or movement.

In addition, since the lower part of the underpants is made of a separate cloth, it is possible to maintain the same wearing comfort as in the prior art.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view showing an embodiment of the underpants according to the present invention, FIG. 2 is a plan view of the underpants, FIG. 3A is a rear view of the underpants, and FIG. ) Is a right side view of the underpants, (C) is a left side view of the underpants, (D) is a bottom view of the underpants, and FIG. 4 is a view of the underpants of the present invention and the skeleton system of the wearer. It is explanatory drawing which looked at the relationship from the back side of the human body.

The skeletal system of the wearer is as shown in FIG. 4, and the spine supporting the skull 1 includes the first cervical vertebra 2a to 2c from the top.
The seventh cervical vertebra 2g, the first thoracic vertebra 3a to the twelfth thoracic vertebra 31, the first lumbar vertebra 4a to the fifth lumbar vertebra 4e, the sacrum 5, and the coccyx 6 are provided. The first rib 7a to the twelfth rib 7l are joined, the clavicle 8 extends substantially horizontally from the upper front side of the first rib 7a to both sides, and the scapula 9 is joined at the tip thereof, and the first rib 7a to the eighth rib 7h. The bones 10 of both hands are joined to the scapula 9 with the shoulder joint 11, the pelvis 12 is joined to the sacrum 5 and the tailbone 6, the iliac 13 is joined to the pelvis 12, and the pelvis 12
Bones 14 of both feet are joined to each other with a hip joint 15 on both sides of the leg. Looking at the vicinity of the lumbar region, the space between the twelfth rib 7l and the iliac 13 and the pelvis 12 extends from the first lumbar vertebra 4a to the fifth lumbar vertebra 4.
e is in a state where only e is arranged.
With the lumbar spine as an axis, the upper body and lower body can perform twisting, bending and stretching, and a combined operation thereof. In addition, pelvis 1
The hip joint 15 serving as a joint between the 2 and both feet has a spherical femoral head 14a supported by a concave spherical receiving seat 12a of the pelvis 12.

As shown in FIGS. 1, 2 and 3, (A) to (D) in FIG. 1, the upper part of the lower part is made of a fabric a in which elastic yarn is knitted. Is composed of different dough b,
The upper fabric a closely covers the waist of the wearer and the vicinity of the lower part of the ischial 16.

The boundary c between the upper fabric a and the lower fabric b is
For example, on both sides, the position is slightly above the position corresponding to the femoral head 14a of the wearer, on the front surface, an upward convex arc line c 'is formed from the positions on both sides, and on the rear surface, a downward convex arc line c "is formed from the positions on both sides. The upper end a 'of the upper cloth a is set to be slightly above the position corresponding to the third lumbar vertebra 4c of the wearer, and the upper and lower cloths are sewn along the boundary line c and integrated to form a lower arm.

[0013] In the upper cloth a of the lower arm made of a knitted cloth knitted with the elastic yarn (for example, spun yarn), the elastic contraction force of the cloth makes close contact with the waist of the wearer, thereby ensuring the waist. It can support and improve the protection of the lumbar spine by the abdominal and back muscles, and does not hinder the wearer's movement or movement due to the elastic expansion and contraction.

Further, since the lower fabric b of the lower frame is made of a separate fabric b knitted with cotton, polyester or other fiber yarns, it is possible to maintain the same wearing comfort as before.

The upper and lower boundary lines c are, for example, slightly above the position corresponding to the wearer's femoral head 14a on both sides, and are formed by upwardly projecting circular arc lines c 'from the positions on both sides on the front surface, and on both sides on the rear surface. If it is constituted by a downward convex arc line c "from the position, the upper fabric a does not interfere with the movement of both feet of the wearer,
The part involved in the displacement of the lumbar spine can be effectively protected by the upper cloth a.

Further, the upper end a 'of the upper cloth a is slightly higher than the position corresponding to the third lumbar vertebra 4c of the wearer, so that the third lumbar vertebra is easy to torsion, flexion and extension, and to combine these operations and weight load. 4c, fourth lumbar vertebra 4d, and fifth lumbar vertebra 4e
Can be protected by the upper cloth a, and pressure interference between the lowermost rib (the twelfth rib 7l) and the upper cloth a can be prevented.

If the front boundary line c is an upwardly projecting circular arc line c ', the wearer does not feel any pressure on the lower abdomen. Furthermore, if the rear boundary line c is a downwardly convex arcuate line c ″ and is set to pass slightly below the position corresponding to the wearer's ischial 16, the wearer's ischium 16, pelvis 12, and iliac 13 are included. From the buttocks to the waist, the elastic yarn can be closely adhered and protected by the cloth knitted.

Although the above-described embodiment has exemplified the underpants for men's briefs, the present invention can also be applied to trunks-types as well as to women's. Upper and lower fabrics a,
The boundary line c of b is not limited to the embodiment shown in the drawings, but may be changed slightly within the scope of the configuration described in the gist of the present invention.

[0019]

According to the present invention, at the upper part of the underpouch made of a cloth knitted with an elastic yarn, the elastic shrinkage force of the cloth tightly adheres to the waist of the wearer to reliably support the waist, The protective action of the lumbar spine by the abdominal muscles and the back muscles can be improved, and the elasticity of the elastic body does not hinder the wearer's exercise or movement.

Further, since the lower part of the lower frame is made of a different material, it is possible to maintain the same wearing comfort as that of the related art.
