Description

  The present invention relates to a bottom apparel such as a long girdle having a leg portion having a length reaching an ankle portion.

Bone and muscle are connected by tendons, and the joint moves when the muscle contracts or relaxes. However, when the muscle weakens due to aging or the like, it becomes difficult to move the joint.
In particular, knee joints that move in a complex manner and are subjected to large shearing forces as well as compression forces are easily damaged.If the strength of the quadriceps and soleus that support the knees decreases, the knees become unstable and wobble or climb up the stairs. It becomes difficult to go down, and knees hurt when standing or sitting (Non-Patent Document 1).

  Conventionally, the upper end of the tibia passes through the vicinity of the lower part of the biceps femoris without passing through the biceps femoris and the muscle abdomen at right angles to the direction of the muscle fibers, passing over the biceps femoris and / or the intestinal shin ligament Do not cross the muscle abdomen of the half-tendon-like muscle and the semi-membranous muscle at right angles to the muscle fiber direction through the strong tightening force part that reaches the vicinity of the head and the vicinity of the semi-membranous muscle and / or the adductor muscle There has been proposed a lower limb protective clothing having a strong tightening force portion that passes through the vicinity of the lower part of the muscle abdomen and reaches the vicinity of the upper end of the radius, and further passes over the vicinity of the gastrocnemius and / or the soleus muscle (PTL 1). ).

Yoshimitsu Hoshikawa, “The specialist will fix! Pain in the knee”, Takahashi Shoten, September 10, 2007, p.22, p.23, p.54, p. 55 Japanese Patent No. 3012819

However, the conventional protective apparel supports the muscles on the back side of the thigh, and has no function of supporting the movement of the knee by supplementing the function of the quadriceps. In addition, if the strong tightening force part is arranged from the waist part to the lower end of the leg part, the leg part of the protective clothing is likely to slide up by that force, and if the tightening force of the entire clothing is strengthened to prevent this, the weak elderly person etc. Was worried that her movement would be disturbed.
The problem to be solved by the present invention is to provide a bottom apparel that is easy to move by reducing the burden applied to the knee by reliably raising the quadriceps and soleus upwards to compensate for its function. is there.

The present invention relates to a bottom garment having a stretchable fabric as a body fabric and having a leg portion whose lower end reaches the ankle portion, the leg portion having a lower end portion that is difficult to stretch in the circumferential direction, and is made of a stretchable fabric. A lift-up piece is arranged along the head muscle, knee and soleus, and the waist and the lower end of the leg are connected by this lift-up piece.
The lift-up piece is arranged over the shin part of the leg part, and the elastic cloth is located between the lift-up piece and the body cloth so as to reach the knee part from the lower end part of the leg part through the shin part. It is preferable to arrange a protective piece made of the same.

In this case, it is desirable that the upper edge of the protective piece is concavely curved upward so as to match the shape of the lower end of the quadriceps.
The protective piece may be formed with a horizontal cut or crease at a vertical position across the patella.
The leg portion of the leg portion along the soleus may have a triple structure in which the lift-up piece and the body cloth are overlapped with a reinforcing piece made of a stretchable cloth.
The inner surface may be raised.

According to the first aspect of the present invention, when the wearer wears, the continuous lift-up piece from the waist part to the lower end part of the leg part is stretched to return to the original length. In addition, the return force of the lift-up pieces arranged along these muscles helps the action of the soleus muscle, and thus the burden on the knee is reduced, especially the large burden applied when the knee is bent and stretched. This relieves knee pain and enables smooth movement of the knee.
According to the second aspect of the present invention, the knee can be lightly compressed and kept warm by the protective piece to protect the knee that is not damaged by the subcutaneous fat and is easily damaged.

According to the third aspect of the present invention, the protection piece does not inhibit the quadriceps muscle from expanding and contracting, so that the knee is easily bent and stretched.
According to the invention which concerns on Claim 4, since a protection piece does not inhibit rotation of a femur and a tibia with respect to a patella, it is easy to bend and extend a knee.
According to the invention which concerns on Claim 5, the position corresponding to the inner soleus muscle which is far from a waist part and the protection piece is not arrange | positioned can be pulled up reliably.
According to the invention which concerns on Claim 6, it can prevent that the whole bottom clothing slip | deviates, can raise a quadriceps and soleus muscles more reliably, and a heat retention effect also increases.

Hereinafter, an embodiment in which the bottom clothing is a long girdle will be described in detail with reference to the drawings. 1 is a front view of the long girdle 1, FIG. 2 is a rear view of the long girdle 1, FIG. 3 is a developed rear view of the body piece 2, and FIG. 4 is a front view of the protective piece 8. 5 is an enlarged view of part A in FIG. 2, and FIG. 6 is an enlarged view of part B in FIG.
As shown in FIGS. 1 and 2, the long girdle 1 of the present embodiment is made of a fabric having a stretchability such as a power net and a relatively strong tightening force. A piece 3 and a waist piece 4 are provided.

In order to form the long girdle 1 with the body piece 2, the abdomen piece 3 and the waist piece 4, the upper rear edge 2 </ b> A of the left and right body pieces 2 are sewn together, and the front edge upper part 2 </ b> B is attached to both side edges of the abdomen piece 3. A waist piece 4 is attached along the upper edges of the body piece 2 and the abdomen piece 3 to form a waist part. In addition, a stretchable lace can be overlapped on the outer surface of the abdomen piece 3 for decoration.
Since the waist part of the long girdle 1 has a triple structure in which the waist piece 4 is folded at the upper edge and a belt-like rubber is sandwiched between them, it does not easily slide up or slide down.
The lower parts of the left and right body pieces 2 are respectively sewn in a cylindrical shape, and the lower ends are leg portions 5 reaching the ankle portion.

As shown in FIG. 3, the left and right body pieces 2 are each provided with one continuous lift-up piece 6 extending from the waist part to the lower end of the leg part 5 and are superposed on the back of the body cloth.
The lift-up piece 6 is made of a stretchable fabric such as a power net, the upper part of which covers the middle ankle muscle, passes through the side of the waist and turns to the front surface of the leg part 5 to the quadriceps, knee and shin parts. The lower end portion of the leg portion 5 protrudes widely toward the back side of the leg portion 5 and is arranged along the soleus. The lift-up piece 6 is made of a stretchable fabric having a tightening force comparable to or slightly stronger than that of the body piece 2, and the yarn used for the body piece 2 and the lift-up piece 6 is 155. Desirably about decitex.
Further, as shown in FIG. 5, the portion along the soleus of the leg 5 has a triple structure in which a reinforcing piece 7 made of a stretchable fabric such as a power net is overlapped between the lift-up piece 6 and the body fabric. . The reinforcing piece 7 reaches the lower end of the leg portion 5, and its periphery is sewn to the lift-up piece 6.

As shown in FIG. 6, a protective piece 8 is disposed between the lift-up piece 6 and the body cloth at a position from the lower end of the leg portion 5 to the knee portion through the shin portion.
The protective piece 8 is made of an elastic fabric that is difficult to expand and contract, such as fiber fill, and its periphery is sewn to the lift-up piece 6.
As shown in FIG. 4, the upper edge of the protection piece 8 is concavely curved upward so as to match the shape of the lower end of the quadriceps. Further, the protective piece 8 is formed with a transverse cut 9 at a vertical position sandwiching the patella.

As shown in FIGS. 1 and 2, a belt-like stretchable lace fabric 10 is attached to the surface of the lower end portion of the leg portion 5 over the entire length in the circumferential direction, and as shown in FIG. Is provided with a belt-like positioning piece 11 made of a stretchable cloth such as a power net over the entire length in the circumferential direction.
Thus, the lower end portion of the leg portion 5 has a triple structure in which the stretchable lace fabric 10, the body fabric, and the positioning piece 11 are stacked, and the lift-up piece 6, the reinforcing piece 7 and the protective piece 8 are partially overlapped. Therefore, the positioning portion 12 is difficult to extend and contract in the circumferential direction and is difficult to slide up when the long girdle 1 is attached. The lift-up piece 6 connects the positioning portion 12 and the waist portion.

Further, among the constituent members of the long girdle 1, at least the body piece 2, the abdomen piece 3, the lift-up piece 6 and the positioning piece 11 have a raised back surface raised, and the long girdle 1 is displaced when worn. It has become difficult.
When the long girdle 1 is worn, the legs 5 are stretched, and the positioning part 12 and the waist part are restricted from sliding up and down. Try to return to the length of. Then, the portion whose tightening force is relatively stronger than the other portions by arranging the lift-up piece 6 tries to lift the positioning portion 12 provided at the lower end portion of the leg portion 5 toward the waist portion. To do.

  The quadriceps muscle is a muscle that straddles the hip and knee joints and affects walking and running. Further, the soleus is a muscle that serves as a stand bone for a human who walks upright, pulling backward so that the body does not fall forward against the ground, and serves as a propulsive force for kicking the ground during walking. This soleus stabilizes the ankle and fixes the shin bone, so that the muscles in the back of the knee and the muscles in the back of the thigh control the entire joint when the knee is bent and extended.

  When the knee is bent, the quadriceps muscles extend and the soleus muscles loosen, supporting the weight by the tension of the quadriceps muscles, reducing the load on the articular cartilage, and reducing the possibility of damaging the articular cartilage. For this reason, when the muscular strength of the quadriceps decreases due to aging or the like, it becomes difficult to bend the knee and support the weight, and walk with the knee extended. This further increases the burden on the articular cartilage. However, when the long girdle 1 of the present invention is worn, the lift-up piece 6 assists the function of the muscular strength of the quadriceps, so that walking with a knee bent is facilitated.

Further, when the knee is extended, the quadriceps muscle contracts and the soleus muscle extends to maintain the posture, reducing the burden on the articular cartilage, but wearing the long girdle 1 of the present invention If so, the lift-up piece 6 assists the action of the quadriceps and soleus muscles and further reduces the burden on the articular cartilage.
If the long girdle 1 of the present invention is worn, the burden on the articular cartilage can be reduced, so the possibility of damaging the articular cartilage is reduced, and the knee pain caused by damage to the articular cartilage is reduced. Can do.

In the present embodiment, the long girdle has been described, but the present invention is not limited to this, and any bottom clothing that exhibits the same action and effect may be used.
Further, a lateral fold may be formed instead of the cut 9 at the vertical position across the patella of the protective piece 8.
Furthermore, in the present embodiment, the lift-up piece 6 is arranged along the outer vastus muscle of the quadriceps femoris, but it can also be arranged so as to extend widely to the position of the rectus femoris muscle.
Moreover, the member which comprises the long girdle 1 is not limited to the said Example. For example, the upper part of the front edge of the left and right body piece 2 may be sewn together without providing the abdominal piece 3 separately.
