  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a side view showing a state in which the body balance function improving sock according to the present invention is worn. The body balance function improving sock 10 is formed on the knitted fabric 11 covering the foot and the ankle from the fourth metatarsophalangeal joint portion 34 on the sole side of the foot 30 on the inner surface side of the knitted fabric 11 as shown in FIG. A pad 25 provided over the fifth metatarsophalangeal joint portion 35 is provided. That is, as shown in FIG. 3 with the body balance function improving socks 10 shown in FIG. 1 turned over, the pad 25 is housed in the bag portion 18 protruding from the sole portion 14.

  The pad 25 is housed in the bag portion 18 of the knitted fabric 11 as shown in FIG. 4 (a) and has an external appearance of a columnar shape or egg shape. A cloth piece is wound around as shown in FIG. 4 (b). It consists of things. As shown in FIG. 4C, the bag portion 18 is knitted into the sole portion 14.

  The pad 25 in the sock 10 with improved body balance function presses the fifth metatarsophalangeal joint portion 35 from the fourth metatarsophalangeal joint portion 35 when a load is applied to the heel, such as during walking or exercise, It functions to expand 5 squares. And even if the somatic balance function improving socks are worn for a long time, there is no discomfort or incongruity.

  The pad 25 can be a rounded cloth piece as described above and used in a cylindrical shape with an outer diameter of 5 to 10 mm in a state of being stored in the bag portion 18, and the length can be 5 to 30 mm. it can. As this fiber, for example, a cloth knit-knitted from polyethylene, polypropylene, polyurethane, polyvinyl chloride, polyester, nylon or the like can be used. Among these, a cloth knitted from polypropylene and polyvinyl chloride fibers is preferable.

  Further, the pad 25 is preferably made of a fiber having an official moisture content (JIS L0105) of 4.5% or less so as not to give discomfort even when the sock with improved body balance function is worn for a long time. This is because if the official moisture content of the pad 25 is high, the pad 25 absorbs moisture and becomes hard, which causes discomfort to the person wearing the sock with improved body balance function. Moreover, it is because there is a possibility that fungi such as molds propagate on the pad 25.

  The bag portion 18 for storing the pad 25 is preferably knitted from a highly stretchable knitted fabric and thin. And it is good to be knitted in the sole 14 knitted from the highly elastic knitted fabric of the knitted fabric 11 described below. As a result, the pad 25 can be easily stored, and the pad can be held at a predetermined position even during walking or exercise.

  As shown in FIG. 1, the knitted fabric 11 is composed of a knitted fabric comprising an instep part 12, a socks part 13, a sole part 14, a heel part 15 and an ankle part 16, and the instep part 12 is a side part of the foot. It is also recommended to be made of a low stretch knitted fabric. The instep portion 12 can be knitted by tuck knitting, for example. The instep part 12 is composed of a low-stretch knitted fabric, and its shape hardly changes. The socks 13, the soles 14, the heels 15, and the ankles 16 are preferably made of a highly stretchable knitted fabric. For example, it can be knitted by a highly elastic knit.

  In the main knitted fabric 11, the degree of expansion / contraction of the low-elasticity knitted fabric can be 30 to 100% in terms of elongation, and the degree of expansion / contraction of the highly elastic knitted fabric can be 80 to 200% in terms of elongation. The elongation rate of the highly stretchable knitted fabric can be 1.0 to 3.0 times, and preferably 1.5 to 2.5 times that of the low stretch fabric.

  In such a knitted fabric 11, the knitted portion 19 of the instep portion 12 and the socks 13 extends from the instep inner edge to the instep outer edge along the metatarsophalangeal joint portion as shown in FIG. Good. The knitting portion 19 is preferably knitted with high tensile strength. Thereby, even when a strong tensile force acts on the knitted portion 19 when the heel is bent or expanded, it can have sufficient strength and durability.

  As shown in FIG. 5, the socks 13 are bifurcated socks having a main toe bag 13a for accommodating the first toes and a large pouch 13b for accommodating the second to fifth toes. It is good to do. Thereby, it becomes easy to expand a wrinkle. In addition, the socks-type body balance function improving socks can be worn with the position of the pad 25 easily adjusted to a predetermined position. However, in the present invention, a socks type in which the socks 13 are integrated may be used.

  As described above, the sock 10 with improved body balance function has a configuration in which the knitted fabric 11 covers the periphery of the low stretch knitted fabric of the instep portion 12 with the high stretch knitted fabric. The joint of the knitted fabric and the highly elastic knitted fabric extends from the instep inner edge to the outer instep edge along the metatarsophalangeal joint. A pad 25 is provided on the inner surface side of the knitted fabric 11 from the fourth metatarsophalangeal joint portion 34 on the sole side to the fifth metatarsophalangeal joint portion 35. In the body balance function improving sock 10, the knitted fabric 11 allows a tightening force to act on the foot as a whole, and an upward tensile force to act on the heel. The pad 25 can be spread when the load is applied to the bag. As a result, the body balance function improving socks 10 can maintain and improve the body function and motor function, particularly the body balance function. In addition, it is possible to prevent gavel varus.

  Further, the sock 10 with improved body balance function does not feel uncomfortable even when worn for a long time, so it can be worn like a normal sock. Furthermore, the conventional socks have a problem in that the first toe or the fifth toe is always in an expanded state, so that the first toe or the fifth toe tends to abut against the surroundings. The sock 10 with improved body balance function does not have such a problem.

  A body balance function measurement test was conducted to compare the body balance function when wearing socks-type body socks with improved socks and when wearing nothing. The body balance function measurement test was performed by measuring the change in the position of the center of gravity when three subjects looked up at the mark on the wall for 60 seconds while standing upright 1 m away from the wall. A screen was set up beside the subject so that they were not affected by the surroundings. Subjects were subject A (male, 22 years old, 160 cm, 60 kg), subject B (male, 21 years old, 183 cm, 90 kg), subject C (male, 22 years old, 170 cm, 58 kg).

  A body balance function measurement test is shown in FIG. FIG. 6 shows a case in which a body balance function improving sock is worn with countermeasures (left side), and a case in which no countermeasure is worn (right side). The horizontal axis and the vertical axis represent the center of gravity displacement (mm). According to FIG. 6, it can be seen that when the body balance function improving socks are worn, the displacement of the center of gravity is smaller than when the socks are not worn, and the body balance function is improved by the body balance function improving socks.
