Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sock that can be suitably worn especially for sports, and relates to a sock that can well fit the movement of the foot during exercise.

[0002]

[Prior art]

 Conventionally, as sports socks, it is generally known that a front yarn made of a non-elastic yarn and a back yarn made of an elastic yarn are aligned and knitted continuously from a mouth portion to a toe portion. . In particular, the surface yarn made of non-elastic yarn is knitted in a completely continuous manner from the mouth portion to the toe portion. Since elastic socks are used in such sports socks, they are preferable because they fit the feet.

By the way, when the sports socks are worn for sports and the like, the exercise conditions of the entire foot are as follows. That is, when walking or running, the human body weight is applied to the foot, and the movement mode of the load at that time is generally such that the weight is concentrated on the heel before landing, and then the foot is moved. Move forward, and finally your weight concentrates on your toes. Then, the toes bend at a right angle to the instep of the foot, kick the ground, and then the other foot is loaded with the weight as described above, which is repeated and the whole body advances. Therefore, during exercise, the toes are always in flexion, that is, the toes are parallel or at right angles to the instep.

As described above, the toes are always in flexion motion, but the socks are tubular weft knitted fabrics formed by circular knitting, so that the toes are perpendicular to the instep of the toes. In addition, tensile force acts on the sock in the toe direction. Then, when the toes are parallel to the instep, the tensile force is released. Therefore, if this pulling force and its release are repeated near the foot of the sock (the part of the sock that corresponds to the instep or arch), the sock gradually moves in the direction of the toes, and the base of the toes There was a case where slack was generated in the part of the socks corresponding to. Due to the slack in the socks, there are drawbacks such that the foot slips and it becomes difficult to run when sports such as walking or running. In addition, if there is slack in the part of the sock that corresponds to the base of the toes, the sock is not comfortable to wear. That is, such slack of socks has various adverse effects on the exerciser.

[0005]

[Problems to be solved by the device]

 Therefore, the inventors of the present invention thought to create a sock that can follow the flexion movement of the toes by changing the knitting structure of the sock. However, it was difficult to change the knitting structure basically because the socks are horizontal knitted fabrics. Therefore, without changing the knitting structure, by knitting a certain part of the sock only with elastic threads, the tensile force caused by the bending motion of the toes is absorbed at this certain part, and The pulling force in the toe direction does not work so much on the foot of the sock, so that the part corresponding to the base of the sock does not sag.

[0006]

[Means for Solving the Problems]

 That is, according to the present invention, each of the body, the heel, the foot, and the toe is knitted by the non-elastic thread and the elastic thread, and the vicinity of the bowl section where the foot is switched to the toe is elastic thread with a constant width. The present invention relates to socks which are characterized by being knitted only by themselves. In addition, in the vicinity of the bowl portion where the foot portion is switched to the toe portion, a plurality of strips having a constant width are lined up in the circumferential direction, and the strips are knitted only by elastic yarns and the total length of the strips is set. Relates to socks characterized by being 1/3 or more of the entire circumference.

The present invention will be described below with reference to the drawings. In the sock according to the present invention, the body part 2, the heel part 3, the foot part 4 and the toe part 5 are knitted by both inelastic threads and elastic threads. As the inelastic yarn, cotton yarn, cotton-polyester blended yarn, cotton-acrylic blended yarn, wool yarn, wool-polyester blended yarn, wool-acrylic blended yarn, polyester yarn, acrylic yarn, nylon yarn and the like are used. As the elastic yarn, polyurethane yarn, polyurethane fiber coated with nylon fiber (FTY), polyurethane fiber coated with cotton fiber (DCY), or the like is used. When knitting, a non-elastic yarn is generally used as a front yarn and an elastic yarn is used as a back yarn. The mouth portion 1 may also be knitted with a non-elastic yarn and an elastic yarn, or may be knitted with only an elastic yarn to form a mouth rubber portion.

In the present invention, in the vicinity of the bowl portion where the foot portion 4 is switched to the toe portion 5, that is, the hatched portion 6 in FIG. 1, is knitted only with the elastic yarn. The bowl portion mentioned here is a portion corresponding to between the arch and the toes. The non-elastic yarn is not used in the shaded portion 6. The width of the shaded portion 6 can be arbitrarily determined, and is generally about 3 cm or less. Particularly preferably, the width is equivalent to one course in the knit structure. If the width of the shaded part 6 exceeds 3 cm, many parts of the foot part 4 and the toe part 5 are formed of elastic threads only, which makes the sock uncomfortable to wear and the strength of the shaded part 6 decreases. Becomes larger and the broken portion 6 tends to break. The length of the shaded portion 6 is preferably 1/3 or more of the entire circumference of the sock at the portion where the shaded portion 6 is provided. If the length of the shaded portion 6 is less than 1/3 of the entire circumference, the bending movement of the toes tends to make it difficult to absorb the tensile force acting on the socks. Therefore, the shaded portion 6 may be provided over the entire circumference of the sock, but if the shaded portion 6 is not provided over the entire circumference, the shaded portion 6 is arranged on the back side of the sock, that is, the bowl portion as much as possible. It is preferable to be provided. This is because the tensile force acting on the socks is greater on the back of the socks.

The hatched portion 6 may be provided in the vicinity of the bowl portion where the foot portion 4 is switched to the toe portion 5, or may be provided in a plurality of two or more. When a plurality of lines are provided, the non-elastic yarn and the elastic yarn may be knitted between the hatched portions 6, or only the non-elastic yarn may be knitted. In the present invention, it is particularly preferable that the width of the hatched portion 6 is one course of the knitting structure and the width between the hatched portions 6 is one course of the knitting structure, and three to five hatched portions 6 are provided. It is preferably provided. Further, it is preferable to provide two to four shaded portions 6 with the width of the shaded portion 6 as two courses of the knitting structure and the width between the shaded portions 6 as one course of the knitting structure. With this configuration, since the shaded portions 6 are provided in a plurality, the pulling force acting on the sock due to the bending motion of the toes can be easily absorbed, and the width of the shaded portions 6 is relatively narrowed. There is little fear that the strength of the area where 6 is provided will decrease.

Further, in the present invention, in the vicinity of the bowl portion where the foot portion 4 is switched to the toe portion 5, as shown in FIG. You may line up. The width of the strip 7 can be arbitrarily determined, but is generally about 3 cm or less for the same reason as described above, and one course of the knitting structure is particularly preferable. The strip body 7 is knitted only with elastic threads, and the strip body 7 absorbs the tensile force acting on the foot portion 4 of the sock. A plurality of strips 7, that is, two or more strips 7, are arranged in the circumferential direction, and generally 3 to 12 strips are arranged in the circumferential direction so as to be point-symmetric. The total length of each strip 7 is 1/3 or more with respect to the entire circumference of the sock in the portion where the strip 7 is provided. If the total length of the strips 7 is less than 1/3, it is difficult to absorb the tensile force acting on the foot portion 4 of the sock due to the bending motion of the toes, which is not preferable. The space between the strips 7 may be knitted with an inelastic yarn and an elastic yarn, or may be knitted with only an inelastic yarn.

[Action and effect of the device]

 In the sock according to the present invention, since the vicinity of the bowl portion where the foot portion is switched to the toe portion is knitted with the elastic thread only, or the strip bodies knitted with the elastic thread are arranged at a predetermined interval, the walking or The elastic thread absorbs the tensile force of the toes of the socks, which is caused by the bending motion of the toes during running, and the toes of the socks do not easily move toward the toes. Therefore, it is possible to prevent the foot portion of the sock from moving toward the toe portion and causing the slack between the foot portion and the toe portion of the sock, that is, the portion of the sock corresponding to the base of the toe. Therefore, when the user wears the sock of the present invention and plays sports, slack does not easily occur at the part of the sock that corresponds to the base of the toes, and the sock is always comfortable to wear. . In addition, the present invention has an effect of preventing the foot from slipping or preventing difficulty in running when exercising such as walking or running.
