[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock having excellent fit to a foot, and more particularly to a sock which is less likely to be displaced from a foot when playing sports.

[0002]

2. Description of the Related Art Conventionally, in order to improve the fit of a sock, an elastic thread is inserted into a mouth or a body when knitting a sock using an inelastic thread. Then, the insertion amount of the elastic yarn is varied in each part so that the sock tightening force against the foot is constant (for example, Japanese Utility Model Publication No. 59-2051 and Japanese Patent Application Laid-Open No. 59-94603). .

[0003] However, the tightening force at each part of the sock depends not only on the insertion amount of the stretchable yarn but also on the amount of the non-stretchable yarn supplied. That is, the tightening force increases as the amount of inelastic yarn supplied increases, and the tightening force decreases as the amount of supplied yarn decreases. Therefore, even if only the insertion amount of the elastic yarn is changed while keeping the amount of supply of the inelastic yarn the same, if the elastic yarn is cut, the inelastic yarn is applied to the sock at the cut position. Sometimes sagging occurred. For this reason, there is also an attempt to obtain a desired tightening force by changing both the supply amount of the inelastic yarn and the insertion amount of the elastic yarn (Japanese Patent Application No. 2-411504). This approach is preferred to obtain the desired tightening force.

[0004] Each of the above-mentioned prior arts is intended to adjust the tightening force of a body part of a sock (a part from a calf to a heel) mainly by adjusting an insertion amount of an elastic yarn. It is not intended to adjust the tightening force of the part from the heel to the toe (the part from the heel of the foot to the tip of the foot). That is, conventionally, attention was paid to the tightening force on the body part of the sock,
He did not care about the tightening force from the heel to the toe. This is because the comfort of socks is largely related to the tightening force in the body,
This is because the tightening force applied to the portion from the heel to the toe was considered to have little relation to the comfort of the sock.

[0005]

However, in the case of socks worn during sports, for example, the tightening force for the portion from the heel to the toe is also important. Because
This is because it is possible to prevent the displacement of the sock with respect to the foot during sports, particularly the displacement of the sock with respect to the back surface of the foot and the instep, thereby improving not only comfort but also mobility. Therefore, when knitting a portion from the heel to the toe, it is conceivable to apply the above-described conventional technology. However, from the heel to the toe,
When the elastic yarn is inserted, the tightening force becomes too large, which impairs mobility.

Therefore, the present invention uses an elastic yarn having the same elasticity as the elastic yarn, and knits the elastic yarn to form a stitch instead of inserting the elastic yarn from the heel to the toe. And a sock having a moderate tightening force on the foot. In other words, paying attention to the fact that the circumference of a human foot generally gradually decreases from the heel to the toe, knit socks using elastic yarn and inelastic yarn, and elasticize from the heel to the toe. By gradually decreasing both the yarn supply amount of the yarn and the inelastic yarn, an appropriate tightening force is obtained from the heel to the toe.

[0007]

That is, the present invention is directed to a sock in which an elastic yarn and an inelastic yarn are knitted, and from the heel to the toe, both the elastic yarn and the inelastic yarn are supplied. Knitting by gradually reducing the amount of yarn , and knitting from the mouth to the heel, that is, the body, by gradually reducing the amount of both elastic and inelastic yarns supplied, and further expanding and contracting The present invention relates to a sock characterized by inserting a thread.

In the present invention, a sock is knitted using both elastic yarns and inelastic yarns. Socks, as is well known,
Using a circular knitting machine, a tubular weft knitted fabric is knitted in the order of mouth 1, body 2, heel 3, foot 4, and toe 5. Therefore, the stitch made of the elastic yarn and the stitch made of the inelastic yarn are knitted in a double manner. As the elastic yarn to be used, polyurethane yarn, yarn in which polyurethane fiber is coated with nylon fiber (FTY), yarn in which polyurethane fiber is coated with cotton fiber (DCY), and the like are used. Examples of the inelastic yarn used include cotton yarn, cotton-polyester blend yarn, cotton-acryl blend yarn, wool yarn, wool-polyester blend yarn, wool-acryl blend yarn, polyester yarn, acrylic yarn, nylon yarn, and the like. Is used. And
In knitting, inelastic yarn is generally used as the front yarn and elastic yarn is used as the back yarn. In addition, the mouth part 1 may be knitted with only elastic yarn to form a mouth rubber part. Further, as the knitting organization of the sock, any organization conventionally used can be used.

Then, the heel part 3 and the foot part 4 are formed with this circular knitting machine.
When the toe portion 5 is knitted, the amount of both the elastic yarn and the inelastic yarn supplied is gradually reduced. When only the amount of elastic yarn supplied is reduced, the tightening force on the foot from the heel to the toe can be kept constant to some extent, but the following points are not sufficient. That is, the stitches formed by the inelastic yarn are in a floating state, and the appearance is poor. Further, when the elastic yarn is cut, the inelastic yarn may be slackened. Also, when only the inelastic yarn supply amount is reduced, a certain amount of tightening force can be applied to the foot from the heel to the toe, but the following points are not sufficient. In other words, the stitches of the elastic yarn are in a floating state, the elasticity of the elastic yarn cannot be sufficiently exhibited, and the tightening force is too small to provide good mobility. Therefore, only by reducing both the amount of the elastic yarn and the amount of the inelastic yarn to be supplied, from the heel portion 3 to the toe portion 5 of the sock, the perimeter of the sock gradually decreases, and the socks are tightened against the foot from the heel to the toe. The power can be kept constant.

[0010] From the mouth 1 to the heel 3, that is, the body 2 is knitted with elastic yarns and inelastic yarns, and is knitted by gradually reducing the amount of both supplied yarns. In this way, body 2
This is because the tightening force on the foot becomes constant. At this time, insert the elastic yarn between the stitches and knit in the wale direction.
I will do it. This is because by inserting the elastic yarn, the tightening force for the calf of the foot can be adjusted. In addition, as the elastic yarn, the same kind of elastic yarn as described above can be arbitrarily adopted.

[0011]

[Operation and Effect of the Invention] As described above, the sock according to the present invention is knitted from the heel to the toe of the sock by reducing the amount of both elastic and inelastic yarns to be fed. The circumference gradually decreases from the heel to the toe. That is, like the circumference of a human foot, it gradually decreases from the toe to the toe, and a moderate tightening force is generated by the elastic thread, so that it fits the human foot well. Therefore, the sock according to the present invention has an effect that the comfort is good, the displacement with respect to the foot during exercise is small, and the mobility can be improved.

[0012] Further, heel portion from the mouth, knitted reduce the yarn feed amount of both the elastic yarn and non-elastic yarn Tei
Therefore , the circumference of the sock gradually decreases from the mouth to the heel. That is, like a human calf, the length gradually decreases toward the heel, and an appropriate tightening force is generated by the elastic yarn. Further, since the elastic yarn is inserted into this portion, the tightening force can be adjusted. Therefore, it fits well on the human calf and can apply a desired tightening force to the body. Therefore, this sock has an effect that the body part can be prevented from slipping down and the comfort is good.
