Depending on which joint of the human body the supporter is used in, and in which scene the supporter is used, a stronger assisting force may be required when extending the joint compared to when bending the joint. No. 2 supporters did not have a structure that effectively met that requirement.

For example, it is preferable that the supporter assists when the joint is extended. For example, the knee joint is bent from a standing position and then the knee joint is extended. While there is gravity assistance when bending the knee joint, it will be against gravity when extending the knee joint, so it is very easy to extend the knee joint if the supporter is strong. In addition, when using a supporter when performing sports, it may be preferable that the supporter has a strong assisting force not only for the knee joint but also for the elbow joint. For example, when shooting in basketball, etc., there is an action of raising the hand above the head and bending the elbow joint and then extending it. it can.

The present invention has been made in view of the above circumstances, and one of its purposes is to provide a supporter that can effectively assist the operation of extending the joint when the joint is extended while protecting the joint. There is.

As a result of reviewing the structure of the conventional supporter, the present inventor cannot obtain strong support force by the supporter when extending the joint with the conventional supporter. It was found that the cause is that it is a low contractile force generating part that is rich in nature and cannot accumulate strong contractive force when stretched. The inside of the joint support ring has a low contraction force generating part because the part in the ring is the most stretched part when the joint is bent. This is because if it is covered with a force generating part, it will hinder bending the joint. However, in such a configuration, when the joint is bent, the contraction force accumulated in the joint support portion is reduced by extending the low contraction force generation portion more than the joint support portion, so that only a weak assisting force is generated. I can't. Based on the above knowledge, the present inventor completed the present invention supporter shown below as a result of trial and error.

The supporter of the present invention has a cylindrical part that covers the joint part of the human body from the outer periphery, and is a high contraction force generating part that is partially formed in the cylindrical part. The high contraction force generating part provided in the supporter includes a joint support part, an upper fastening part, a lower fastening part, and a belt-like part. The joint support portion is a portion that surrounds a portion protruding when the joint is bent in an annular shape. The upper tightening portion is continuous with the joint support portion, extends from the joint support portion to the left and right of the tubular portion, and extends upward from the tubular portion. The rear surface of the tubular portion opposite to the joint support portion It is the part formed so that it may be connected by. The lower tightening portion is a portion that is continuous to the joint support portion, extends from the joint support portion to the left and right of the tubular portion, extends below the tubular portion, and is connected to the back surface of the tubular portion. is there. The band-shaped portion is a portion that connects the joint support portion in the vertical direction of the tubular portion so that two low contraction force generating portions divided on the left and right of the tubular portion are formed in the ring of the joint support portion. .

As one form of the supporter of the present invention, it is preferable that the belt-like portion provided on the supporter becomes gradually wider from the upper part of the joint support part toward the center of the ring and gradually becomes narrower from the center of the ring to the lower part of the ring.

As one form of the supporter of the present invention, the high contraction force generating portion provided in the supporter further includes a connecting portion that connects the upper tightening portion and the lower tightening portion in the vertical direction of the tubular portion on the back surface of the tubular portion. Is preferred.

Further, as one embodiment of the supporter of the present invention, a knitted fabric knitted into a tubular shape without sewing by a flat knitting machine having at least a pair of front and back needle beds is preferable.

According to the supporter of the present invention, not only can the bending and stretching operations of the joint be supported, but also the operation of stretching the joint can be effectively assisted. This is because when the joint is bent, the joint support portion is stretched more than the conventional configuration when the joint is bent by the band-like portion that connects the inside of the joint support portion in the vertical direction, and a strong contraction force is accumulated. In addition, since the belt-like portion itself is stretched to accumulate the contraction force, the contraction force accumulated in the entire high contraction force generation unit is increased. Moreover, since the belt-like portion is provided along the vertical direction of the cylindrical portion, the contraction force accumulated in the entire high contraction force generating portion is mainly along the vertical direction of the cylindrical portion, that is, along the operation of extending the joint. Acts in the opposite direction. On the other hand, the position of the joint support part relative to the joint part can be suppressed by the low contraction force generation part formed in the joint support part ring by the belt-like part, and the low contraction force generation part exists in the ring of the joint support part By doing so, it is possible to eliminate the difficulty of bending the joint.

Note that the supporter of the present invention is effective for supporting not only the elbow joint and the knee joint but also any joint part of the human body. For example, you may apply the structure of this invention to the supporter which protects a wrist, an ankle, a finger, and a toe.

According to the supporter of the present invention in which the middle part of the belt-like part is formed wide, the contraction force generated in the belt-like part can be increased, and the belt-like part can be made difficult to be displaced from a portion protruding when a joint such as an elbow or knee is bent.

According to the supporter of the present invention having the connecting portion, it is possible to protect the joint from being damaged when the joint is extended. This is because the connecting portion that connects the upper tightening portion and the lower tightening portion in the vertical direction of the cylindrical portion brakes the movement of the joint to extend before the joint extends.

) According to the supporter knitted into a tubular shape without sewing using a flat knitting machine, since there is no joint by sewing, the configuration of each part provided in the supporter can be effectively used. Since the joint by sewing hardly stretches, for example, if there is a joint so as to divide the high contraction force generating portion, the contraction force may be divided by the joint.

BRIEF DESCRIPTION OF THE DRAWINGS It is the schematic of the supporter for elbow joints concerning embodiment, Comprising: (A) is the figure seen from the side corresponding to an elbow at the time of wear, (B) is seen from the side corresponding to an elbow fossa (cubal fossa) at the time of wear It is a figure.

In this embodiment, an elbow joint supporter will be described with reference to FIG. A supporter 10 shown in FIG. 1 is a tubular knitted

fabric having openings

8 and 9 on the upper and lower sides, slightly curved in the shape of the elbow (fitting) along the elbow joint along the elbow joint, This supporter 10 has a high contraction force generator 10H that has a low stretchability, requires a large tension to stretch, and exerts a strong contraction force once stretched. The low contraction

force generation units

10L and 5 other than the high contraction force generation unit 10H are more stretchable than the high contraction force generation unit 10H, and the contraction force generated when they are stretched is also high. It is a portion smaller than the contraction force generation unit 10H.

The supporter 10 can be knitted without sewing by a flat knitting machine including a pair of opposed needle beds and a plurality of yarn supplying members. For example, a normal knitting yarn is supplied from a yarn supplying member of a flat knitting machine, and an elastic yarn is supplied from another yarn supplying member, and the supporter 10 is knitted around. At that time, the elastic yarn is plated and knitted in the portion corresponding to the high contraction force generating portion 10H, and the elastic yarn is tack knitted in the portions corresponding to the low contraction

force generating portions

10L and 10L. In addition, elastic yarns having different tensions may be used in the high contraction force generation unit 10H and the low contraction

force generation units

10L and 5 or after the supporter 10 having uniform stretchability is knitted, the resin is partially resinated. May be impregnated to form the high contraction force generating portion 10H.

The high contraction force generating part 10H partially formed on the supporter 10 includes a joint support part 1, an upper fastening part 2, a lower fastening part 3, and a belt-like part 4. When the supporter 10 is worn, the opening 8 with the upper tightening portion 2 is on the lower arm side, and the opening 9 with the lower tightening portion 3 is on the upper arm side.

The joint support portion 1 is an annular portion provided at a position corresponding to the elbow when the supporter 10 is worn, as shown in FIG. When the elbow is bent, the joint support portion 1 extends so as to expand in the radial direction from the center of the ring, generates a contraction force toward the center, and reduces the force applied to the joint. Further, the contraction force generated in the joint support portion 1 when the elbow joint is bent is accumulated in the joint support portion 1 and works as part of the assisting force when the elbow joint is extended.

As shown in FIG. 1 (A), the upper tightening portion 2 is formed continuously from the joint support portion 1 and is divided into two parts on the left and right from the joint support portion 1 and extends above the supporter 10. As shown in B), it is formed by being connected on the back side of the supporter 10. On the other hand, as shown in FIG. 1 (A), the lower tightening portion 3 is formed continuously from the joint support portion 1, and is divided into two parts on the left and right from the joint support portion 1 and extends below the supporter 10. As shown to 1 (B), it forms by connecting with the back side of a supporter. These tightening

portions

2 and 3 serve to tighten the arms in the circumferential direction so that the position of the supporter 10 does not shift, and extend in the vertical direction of the supporter 10 and accumulate the contracting force in the vertical direction. be able to. The contraction force accumulated in the tightening

portions

2 and 3 is transmitted to the joint support portion 1 connected to the tightening

portions

2 and 3, and works as a part of the assisting force for extending the elbow joint. Further, since the tightening

portions

2 and 3 are connected to the joint support portion 1, when the elbow joint is bent, the joint support portion 1 is pulled in the vertical direction of the cylindrical portion, and the joint support portion 1 is moved in the vertical direction. It contributes to generating further contraction force.

The belt-like portion 4 is a wide portion connecting the inside of the joint support portion 1 up and down. The width of the belt-like portion 4 gradually increases as it goes from the upper part of the joint support part 1 toward the center of the ring, and gradually becomes narrower as it goes from the center of the ring to the lower part of the ring. The shape is symmetrical with respect to the vertical line. The band-like portion 4 may have a uniform width. However, as shown in the embodiment, the band-like portion 4 is less likely to be displaced from the position of the elbow when the middle portion of the band-like portion 4 is formed wider.

When the elbow joint is bent, the contraction force in the vertical direction of the supporter 10 accumulated in the entire high contraction force generation unit 10H can be increased more than in the conventional case by the belt-like part 4 connecting the joint support part 1 up and down. . Of course, since the belt-like portion 4 itself also stretches and accumulates contraction force, the accumulated contraction force becomes a part of the assisting force when the elbow joint is extended.

Between the belt-like portion 4 and the joint support portion 1, two crescent-like low contraction

force generating portions

5, 5 are formed. The two low contraction

force generating portions

5 and 5 of the embodiment are symmetrical with respect to each other across a center line extending in the vertical direction of the supporter 10. These low

contraction force generators

5 and 5 are portions that can be extended with a lower tension than the high contraction force generator 10H, and the generated contraction force is also small. Since the portion corresponding to the elbow in the supporter 10 is the portion that is most stretched when the elbow is bent, if the entire portion is formed of a high contraction force generating portion that is difficult to stretch, a large force is required to bend the elbow joint. It is necessary to bend the elbow joint, such as the joint support portion 1 does not fit the elbow position. On the other hand, since the low contraction

force generating portions

5 and 5 are formed in the portion corresponding to the elbow, the low contraction

force generating portions

5 and 5 extend greatly when the elbow joint is bent. The joint can be bent. Moreover, since the low contraction

force generating portions

5 and 5 are arranged so as to sandwich the belt-like portion 4, positional deviation of the belt-like portion 4 with respect to the elbow can be effectively prevented.

In addition, as shown by a two-dot chain line in FIG. 1 (B), a connecting portion 7 that connects the upper tightening portion 2 and the lower tightening portion 3 may be provided on the back side of the cylindrical portion 10. Then, by forming the connecting portion 7 so as to be difficult to extend similarly to the high contraction force generating portion 10H, the operation of extending the elbow joint before the elbow joint is extended by the connecting portion 7 is braked, and the elbow joint is It can be protected from pain. The connecting part 7 acts as a brake for extending the elbow joint because the supporter 1 has a slightly curved “(” shape on the elbow socket side, so that the supporter 1 is straightened. This is because the part 7 resists.

On the other hand, the low contraction force generation unit 10L is a part that generates a contraction force lower than that of the high contraction force generation unit 10H when extended. The presence of the low contraction force generating portion 10L makes it easy to attach and detach the supporter 10 to and from the arm and the arm is not excessively tightened.

The supporter 10 formed by the low contraction

force generation units

10L, 5 and the high contraction force generation unit 10H described above is partially stretchable so that it can be easily attached to and detached from the arm and bends the elbow joint. The elbow joint can be effectively protected so as not to hinder extension. Moreover, the supporter 10 can effectively assist the movement of extending the elbow joint by including the belt-like portion 4 and the low contraction

force generating portions

5 and 5.

The configuration of the present invention is not limited to the elbow joint supporter, but can also be applied to a knee joint supporter, a wrist joint, an ankle joint supporter, and the like. Further, the structure of the present invention is applied to a portion corresponding to the knee joint and ankle joint of the clothing covering the entire lower body like stockings, or a portion corresponding to the wrist joint and the elbow joint of the clothing covering the entire upper body like a sweater. May be applied.
