[Technical field to which the invention belongs]

 The present invention relates to a sock, and more particularly to a so-called short sock in which an opening is located in a calf of a foot when the sock obtained by knitting is worn.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, among socks, a so-called short sock in which an opening is located at a calf of a foot when worn, is usually formed by tubular knitting by a sock knitting machine. In such a short sock, as shown in FIG. 3, the leg 100a including the opening 100b and the ankle 101 of the sock 100 is formed in a cylindrical portion having substantially the same inner diameter, and the opening 100b has The elastic fibers 102, 102,... The opening 100b prevents the leg 100a from slipping off the calf of the foot when the socks 100 are worn. However, as shown in FIG. 3, when wearing the socks 100, the calf L of the person's foot where the opening 100b is located has a tapered shape that gradually becomes thicker in the direction from the ankle to the knee. Therefore, the opening 100b of the sock 100 located on the calf L which is thicker than the ankle gradually slips in the ankle direction as shown in FIG. easy. Further, since the opening 100b as the rubber band portion tightens the calf L which is thicker than the ankle and the vicinity thereof, the tightening feeling is strong.

[0005] In order to prevent the legs of the socks from slipping down, Japanese Utility Model Publication No. 6-19521 proposes a sock 200 shown in FIG. In the socks 200, the leg portion 202 including the ankle portion 202c and the opening 202a is formed in a cylindrical portion having substantially the same inner diameter, and although the elastic fiber 204 is not woven in the opening 202a, Elastic fibers 204 are woven in an annular shape in the ankle portion 202c and the intermediate portion 202b (between the opening portion 202a and the ankle portion 202c). Further, elastic fibers 204, 204,... Are knitted at a higher density in the ankle portion 202c of the leg portion 202 than in the intermediate portion 202b.

[0004]

[Problems to be solved by the invention]

 According to the socks 200 shown in FIG. 5, when the socks 200 are worn, the ankles in the portion thinner than the calf L and the portions of the socks 200 located near the ankles, that is, the ankles 202 c and the middle portions 202 b of the legs 202. Since the feet are tightened, the feeling of tightening the calf L can be reduced more than the socks 100 shown in FIG. 3 and slippage can be prevented. However, in the socks 200 shown in FIG. 5, the opening 202a where the elastic fiber 204 is not woven is easily slipped off. Further, the leg 202 including the ankle 202c and the intermediate part 202b in which the elastic fibers 204 are woven is formed as a cylindrical part having substantially the same inner diameter. For this reason, the feeling of tightening the tapered calf L by the leg 202 is still strong, and there is a demand for a sock that can further reduce the feeling of tightening the calf L by the leg 202 and exhibit a good wearing feeling. . In response to such a demand, the present inventor formed the leg 202 of the sock 200 as a tapered portion whose inner diameter gradually increases from the ankle 202c to the opening 202a so as to follow the shape of the calf L. The elastic fiber was not woven into the opening 202a, and as shown in FIG. 4, the leg 202 easily slipped in the direction of the ankle 202c. Therefore, an object of the present invention is to provide a sock that can reduce the feeling of tightening at the leg of the sock and prevent the leg from slipping down as much as possible.

[0005]

[Means for Solving the Problems]

 As a result of studying to solve the above-mentioned problem, the present inventors knit elastic fibers in an annular shape over the entire leg under the socks, and at the ankle of the leg, the elastic fibers are denser than the other parts of the leg. By knitting the socks and forming the legs under the socks in a tapered portion whose inner diameter gradually increases from the ankle toward the opening, the socks can be prevented from slipping down in the ankle direction as much as possible, In addition, the present inventors have found that the feeling of tightening at the legs under the socks can be reduced, and have reached the present invention. That is, in the present invention, when wearing a sock obtained by knitting a tube, the sock in which the opening is located on the calf of the foot worn over the entire leg including the ankle and the opening of the sock. Elastic fibers are knitted, elastic fibers are knitted in the ankle of the leg more densely than the other parts of the leg, and the leg is opened from the ankle to the opening. The socks are characterized by being formed in a tapered portion whose inner diameter gradually increases in the direction. In the present invention, the elastic fibers are knitted annularly at predetermined intervals on the legs, and the intervals between the elastic fibers knitted on the ankles of the legs are adjusted to the intervals between the elastic fibers knitted on other portions of the legs. It is preferable that the interval between the elastic fibers woven in a loop around the ankle portion of the leg is narrower than the interval between the elastic fibers woven in the loop around the other portion of the leg.

According to the socks of the present invention, elastic fibers are knitted in the entire leg portion, and the elastic fibers are knitted in the ankle portion of the leg portion at a higher density than in other portions of the leg portion. Thus, it is possible to prevent the legs from slipping over the entire legs. In addition, the leg under the socks is formed in a tapered portion whose inner diameter gradually increases in the direction from the ankle to the opening so as to follow the shape of the tapered calf gradually expanding from the ankle to the knee. The density of the elastic fiber woven into the portion of the leg closer to the opening than the ankle is lower than the density of the elastic fiber woven into the ankle. For this reason, when wearing the socks according to the present invention, the feeling of tightening the calves due to the legs of the socks can be reduced.

[0007]

[Embodiment of the invention]

 FIG. 1 shows an example of a sock according to the present invention. The socks 10 shown in FIG. 1 are obtained by tubular knitting with a sock knitting machine. As shown in FIG. 1, the obtained sock 10 is a sock in which an opening 10a (refers to an insertion opening into which a foot is inserted and the vicinity thereof) is located on a calf L of a foot worn. Short socks or socks called socks. The socks 10 have elastic fibers 14, 14... Woven all over the leg 12 including the ankle 12 b and the opening 10 a, and the leg 12 has an ankle 12 b. Elastic fibers 14, 14... Are woven at a higher density than the portion of the opening 12 on the side of the opening 10a (hereinafter, the other portion 12a). Thus, when the socks 10 are worn, the ankles are narrowed by the ankles smaller than the calf L and the socks of the socks 10 located near the ankles, that is, the ankles 12b of the legs 12, and the other parts of the legs 12 are tightened. Even at 12a, the calf L is lightly tightened, so that the legs of the socks 10 can be prevented from slipping down.

Further, the sock 10 has a leg portion 12 formed in a tapered portion whose inner diameter gradually increases in the direction from the ankle portion 12b to the opening portion 10a. In this way, by forming the leg portion 12 in a tapered portion, the shape of the leg portion 12 of the socks 10 can be made to follow the tapered calf L gradually expanding from the ankle to the knee. For this reason, even if the elastic fibers 14, 14,... Are woven into the other portion 12a of the leg portion 12, the feeling of tightening the calf L can be reduced. Moreover, since the elastic fibers 14, 14,... Woven into the other portion 12a of the leg 12 have a lower density than the elastic fibers 14, 14,. The feeling of tightening the calf L by the portion 12a can be further reduced.

The elastic fibers 14, 14... Woven into the legs 12 of the socks 10 in FIG. 1 are fibers exhibiting rubber elasticity, such as polyurethane fibers. As shown in FIG. The legs 12 are made of a knitted fabric of inelastic fibers 16 such as fibers, and are knitted in an annular shape (spiral shape). The gap between the elastic fibers 14, 14,... Is smaller at the ankle portion 12b than the gap between the elastic fibers 14, 14,... Of the other portion 12a, and the elastic fibers 14, 14,. In particular, by setting the interval between the elastic fibers 14, 14,... Of the other portion 12a to be １ ／, the sock 10 can be easily manufactured by a sock knitting machine as described later, which is preferable.

When knitting the sock 10 shown in FIG. 1 using a sock knitting machine for warp knitting, the inelastic fiber 16 is supplied to the cylinder in which the knitting needle is rotated in one direction while the cylinder in which the knitting needles are arranged in a ring is rotated. To knit the legs 12. At this time, by supplying the elastic fiber 14 to the cylinder, the elastic fiber 14 can be knitted into the leg portion 12 in a ring shape. The gap between the elastic fibers 14 to be woven can be adjusted by adjusting the supply amount of the elastic fibers 14 to the cylinder. For example, the gap between the elastic fibers 14 to be woven can be narrowed by reducing the supply amount of the elastic fibers 14, and the gap between the elastic fibers 14 to be woven can be widened by increasing the supply amount of the elastic fibers 14.

As described above, the elastic fiber 14 woven into the leg portion 12 can form a thick portion and details on the leg portion 12 by its elastic force. That is, the portion of the leg portion 12 knitted by reducing the supply amount of the elastic fiber 14 can be formed in detail, and the portion of the knitted leg portion 12 by increasing the supply amount of the elastic fiber 14 can be formed in a thick portion. . For this reason, when knitting the ankle part 12b of the leg part 12, the supply amount of the elastic fiber 14 is adjusted, and the elastic fiber 14 is knitted for each stitch. Further, when knitting the other portion 12a of the leg portion 12, the supply amount of the elastic fiber 14 is made larger than the supply amount of the elastic fiber 14 when knitting the ankle portion 12b. Weave the elastic fibers 14. In this manner, the leg 12 is knitted by adjusting the supply amount of the elastic fiber 14 between the ankle portion 12b and the other portion 12a, so that the leg portion 12 is made use of the elastic force of the elastic fiber 14, and the ankle portion is used. It can be formed in a tapered portion whose inner diameter gradually increases in the direction from the opening 12b to the opening 10a. Although the method of manufacturing the socks 10 shown in FIG. 1 has been described using a socks knitting machine for a vertical knitting as a socks knitting machine, the socks 10 shown in FIG. 1 can be manufactured by using a socks knitting machine for a flat knitting. Can be built.
