Summary of the Invention
Problems to be Solved by the Invention
[0005] However, in the above-described sock, only the structure due to the three-dimensional shape for preventing displacement in the vicinity of the heel portion has a drawback that displacement, wrinkles, and sagging occur in the toenail, ankle, heel, and instep of the foot.
[0006] Therefore, the present invention aims to provide socks that form a three-dimensional shape that fits from below the ankle to the arch of the foot, preventing misalignment, wrinkles, and sagging, while also improving the fit to the foot. [Means for solving the problem]
[0007] In view of the above problems, the present invention provides a sock that is formed so that the entire sock from the opening to the toe is approximately L-shaped, The heel portion has an upper part that covers the area below the ankle bone around the heel of the foot, a central part that closely covers the heel, and a front part that covers the arch of the sole of the foot. The aforementioned upper portion is formed from a first stitch reduction region, a first tubular knitting region, and a second stitch reduction region, in order to closely cover the area below the ankle. The central portion is formed from a second tubular knitting region, a stitch count increase / decrease region, and a third tubular knitting region, following the second stitch count decrease region of the upper portion. The front portion is characterized by being formed from a third stitch count increase region following the third tubular knitting region of the central portion.
[0008] Furthermore, the present invention relates to a sock that is formed so that the entire sock from the opening to the toe is approximately L-shaped, The heel portion has an upper part that covers the area below the ankle bone around the heel of the foot, a central part that closely covers the heel, and a front part that covers the arch of the sole of the foot. The aforementioned upper portion is formed from a first stitch count increase region, a first tubular knitting region, and a second stitch count decrease region, in order to closely cover the area below the ankle. The central portion is formed from a second tubular knitting region, a stitch count increase / decrease region, and a third tubular knitting region, following the second stitch count decrease region of the upper portion. The front portion is characterized by being formed from a third stitch count increase region following the third tubular knitting region of the central portion.
[0009] In addition to the above-described configuration, it is preferable that the maximum width of the first stitch count reduction area in the upper part has a length that reaches the instep and is the same length as the maximum width of the third stitch count increase area in the front part.
[0010] In addition to the above-described configuration, it is preferable that the maximum width of the second stitch count reduction area in the upper part has a length that reaches the instep and is the same length as the maximum width of the third stitch count increase area in the front part.

Mode for Carrying Out the Invention
[0015] (First Embodiment) The sock according to the first embodiment of the present invention will be described in detail based on Figs. 1 to 3. The knitted fabric constituting the three-dimensional shape of the sock to be described later is a combination of a tubular knitting area, a stitch count increasing area, a stitch count decreasing area, and a stitch count increasing and decreasing area. This tubular knitting area is a knitted fabric formed in a tubular shape by rotating the knitting cylinder in a certain direction and involving all needles in knitting. The stitch count decreasing area is an inverted trapezoidal knitted fabric formed by reciprocally rotating the knitting cylinder within a range of a predetermined rotation angle and gradually decreasing the number of needles involved in knitting to reduce the stitch count. The stitch count increasing area is a trapezoidal knitted fabric formed by reciprocally rotating the knitting cylinder within a range of a predetermined rotation angle and gradually increasing the number of needles involved in knitting to increase the stitch count. The stitch count increasing and decreasing area is a knitted fabric combining the stitch count increasing area and the stitch count decreasing area without passing through the above-described tubular knitting area.
[0016] As shown in Fig. 1, the sock has an opening 1, a leg part 2 covering from below the knee to the ankle, a heel part 3 covering the periphery of the heel, a body part 4 covering the instep and the sole, and a toe part 5 covering the toes, and is formed so as to be substantially L-shaped as a whole from the opening 1 to the toe part 5.
[0017] The leg part 2 and the body part 4 are formed from the tubular knitting area. The toe part 5 is formed by sewing a knitted fabric combining the stitch count increasing and decreasing areas so as to close the opening on the front side of the body part 4, similar to the central part 20 of the heel part 3 to be described later.
[0018] The heel portion 3 is formed from an upper portion 10 that covers the area below the ankle bone K around the heel of the foot, a central portion 20 that closely covers the heel, and a front portion 30 that covers the arch of the sole of the foot.
[0019] A more detailed explanation of the structure of the heel portion 3 will be given based on the exploded view in Figure 2. The upper portion 10 is formed from a first stitch reduction region 11, a first tubular knitting region 12, and a second stitch reduction region 13, in order to closely cover the area below the ankle bone K.
[0020] The maximum width W1 between vertices A and B located on the leg portion 2 side of the first stitch reduction region 11 is larger than the maximum width W2 between vertices C and D of the second stitch reduction region 13, and has a length that reaches the instep side, and is formed to be the same length as the maximum width W4 between vertices GH of the third stitch increase region 31 of the front portion 30, which will be described later. At this time, it is preferable that the vertical width h2 of the second stitch reduction region 13 be in the range of 1 to 1.25 times the vertical width h1 of the first stitch reduction region 11.
[0021] It is preferable to form this first tubular knitting region 12 as narrow as possible so as close as possible between the first stitch reduction region 11 and the second stitch reduction region 13.
[0022] The central section 20 is formed from a second tubular knitting section 21, a stitch count increase / decrease section 22, and a third tubular knitting section 23, which are continuations of the second stitch count decrease section 13 of the upper section 10.
[0023] The stitch count increase / decrease region 22 is formed by increasing and then decreasing the stitch count following the second tubular knitting region 21, creating two consecutive roughly hexagonal knitted fabrics. This stitch count increase / decrease region 22 has a maximum width W3 between the vertices EF located on the arch side of the foot. Preferably, this width W3 between vertices EF is equivalent to about two-fifths the number of needles of the second tubular knitting region 21.
[0024] The front section 30 is formed from a third stitch-increasing section 31 that gradually increases the number of stitches, following the third tubular knitting section 23 of the central section 20. This third stitch-increasing section 31 has a width that is approximately the same as the width W3 of the stitch-increasing / decreasing section 22 of the central section 20, and the number of stitches gradually increases from there, with a maximum width W4 between the vertices GH that follow the main body section 4. Preferably, this width W4 between the vertices GH is about 1.8 to 2.2 times the width W3 of the stitch-increasing / decreasing section 22 of the central section 20.
[0025] More specifically, the heel section 3 described above, when the number of needles in the tubular knitting area of the leg section 2 is 144, is formed by gradually decreasing the number of needles from 108 to 100 in the first stitch count reduction area 11. The second stitch count reduction area 13 is formed by gradually decreasing the number of needles from 70 to 60 in the third stitch count increase area 31, where the three-dimensional shape is formed by gradually increasing the number of needles from 56 to 108 in the knitting process.
[0026] (Second Embodiment) Next, the socks of the second embodiment will be described with reference to Figure 4-6. Note that for components similar to those of the first embodiment described above, only reference numerals are used in the drawings, and detailed explanations are omitted.
[0027] As shown in Figures 4 and 5, the upper portion 10 is formed from a first stitch count increase region 11', a first tubular knitting region 12, and a second stitch count decrease region 13 in order to closely cover the area below the ankle bone K. The maximum width W2 between vertices CD in the second stitch count decrease region 13 is larger than the width W1' between vertices A'B' located on the leg portion 2 side, and has a length that reaches the instep side, and is formed to be the same length as the maximum width W4 between vertices GH in the third stitch count increase region 31 of the front portion 30.
[0028] (Third embodiment) Next, the sock of the third embodiment will be described with reference to Figure 7-9. In addition to the first embodiment described above, this sock has a ribbed knit area 40 with a height of about 4 to 8 mm near the heel portion 3 and in the knitted fabric that goes around the ankle.
[0029] Furthermore, the leg portion 2 has a tubular knitted fabric that covers from below the knee to the ankle, and in this fabric, elastic yarn is inserted into the knitted fabric from the opening 1 to the part that does not exceed the peak of the ankle bone K (especially the inner ankle bone K) to form a ribbed knitted region 41.
[0030] Therefore, in the state in which the socks of the first and second embodiments described above are worn on the foot as shown in Figures 3 and 6, the vertex AB of the first stitch count reduction region 11 or the vertex CD of the second stitch count reduction region 13 in the upper part 10 of the heel portion 3 is aligned with the vertex GH of the third stitch count increase region 31 in the front portion 30, along the inclined surface S of the ankle. This allows the socks to fit snugly from below the ankle bone K to the arch of the foot, preventing misalignment, wrinkles, and sagging, and improving the fit to the entire foot.
[0031] Furthermore, in the heel portion 3 of the sock of the second embodiment, a first stitch count increase region 11' is provided instead of the first stitch count decrease region 11 of the upper portion 10 of the first embodiment, and the width A'B' of the first stitch count increase region 11' is made smaller than the width W2 of the second stitch count decrease region 13. This provides a three-dimensional shape below the ankle bone K, allowing for a closer fit to the area below the ankle bone K and preventing wrinkles and sagging.
[0032] Furthermore, in the third embodiment, the leg portion 2 of the sock is provided with a ribbed knitted area 40 in which elastic yarn is inserted near the heel portion 3, thereby creating a knitted fabric that is elastic and can be tightened below the ankle bone K, thereby further preventing the heel portion 3 from shifting position.
[0033] Furthermore, the leg portion 2 of the sock in the third embodiment has a knitted fabric that covers from below the knee to the ankle, and by providing a ribbed knitted area 41 in the knitted fabric from the opening 1 to the part that does not exceed the top of the ankle bone K, it is possible to prevent misalignment and sagging from below the knee to the ankle, where the ankle is movable.
[0034] The above embodiments illustrate preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and improvements and modifications are possible within the scope described in the claims. For example, the socks of this embodiment may use a pile knit fabric with higher elasticity. [Explanation of Symbols]
