Description

  The present invention relates to a sock that is advantageous for preventing tripping caused by unevenness or a step on a floor surface during walking.

  In general, many socks are knitted so that the instep portion and the sole portion have the same number of knitting courses so that the entire sock fits on the foot mainly on the comfort (see, for example, Patent Document 1). .)

JP-A-9-157907

  However, in the above socks knitted so that the number of knitting courses of the instep and the sole are the same, elderly people with weak feet, etc., sent out the feet forward with the toes lowered during walking, that is, You will walk with sliding feet, and even a few millimeters of unevenness or steps on the floor may trip. In this way, tripping accidents are likely to occur.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a sock that is advantageous for preventing tripping caused by unevenness or a step on a floor surface.

According to the present invention, in the sock in which the instep portion and the sole portion are circularly knitted as described in claim 1, the entire instep portion has a number of knitting courses per unit length than that of the sole portion. It is knitted so as to apply a pulling force to the toe part so that the instep part warps the toe part upward, and the ankle part connected to the upper side of the instep part is connected to the ankle of the foot. It is knitted into a shape that is tightly squeezed so that it is strongly tightened and does not slip off, and the above-mentioned sole part is a composite knitting of a circular knitting and an inverted knitting that reverses at a place corresponding to the above-mentioned sole part knitting place, It is characterized by being knitted so that the number of knitting courses is larger than that of the instep .
According to the sock constructed in this way, the instep part knitted so that the number of knitting courses per unit length is less than that of the sole part is less stretched in the vertical direction, and the ankle part is not worn when worn. Because it is firmly tightened to the ankle of the foot and held so that it does not slip off, the instep can be assisted or warped upward by pulling the toe part securely to the instep side when wearing. It helps to prevent falls.

  As described in claim 2, the sock described in claim 1 is formed by knitting rubber threads in the ankle portion. According to this, the pulling action of the toe part by the instep part can be performed more reliably.

  In the sock according to claim 1 or 2, as described in claim 3, the toe portion is formed in a sock-like shape in which the thumb bag portion and other finger bag portions can be divided. According to this, it is possible to reduce the burden on the finger that warps the foot.

  According to the present invention, by using the instep part that reduces the number of knitting courses per unit length than the sole part, it is possible to assist or warp upward by pulling the toe part toward the instep part side when worn. In addition, since the ankle part is strongly tightened to the ankle of the foot when worn and is held so as not to slip off, it can be prevented from tripping due to irregularities or steps on the floor surface and can walk safely.

  Preferred embodiments of socks according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a sock according to the present invention is knitted by a sock circular knitting machine or the like, and sequentially from a cuff side to a toe side, a cuff part 1, a leg part 2, an ankle part 3, and a heel part. 4, an instep part 5, a sole part 6, and a toe part 7.

  The instep part 5 and the sole part 6 are knitted fabrics having different degrees of stretch in the vertical direction by changing the number of knitting courses per unit length. That is, the entire instep portion 5 is knitted so that the number of knitting courses per unit length is less than that of the sole portion 6 so that the instep portion 5 is less likely to extend in the vertical direction A than the sole portion 6. .

  An example of a mesh knitting method of the instep part 5 and the sole part 6 of the sock will be described. FIG. 2 shows the formation of the stitches of a normal circular knitting machine, and the knitting yarn 8 is spirally advanced in one direction C around a cylinder (not shown) so that the instep portion 5 and the sole portion 6 are moved. Although the number of knitting courses is knitted to the same number, in the present invention, as shown in FIG. 3, the normal circular knitting shown in FIG. 2 and the inverted knitting that is reversed approximately half the circumference of the cylinder (corresponding to the sole knitting portion) With the composite knitting, the instep portion 5 that reduces the number of knitting courses and the sole portion 6 that increases the number of knitting courses are continuously knitted. An example of the knitting structure knitted by composite knitting in this way is shown in FIG. The instep part 5 and the sole part 6 made of knitted fabrics having different degrees of stretch in the vertical direction can be obtained. The instep part 5 having a small number of knitting courses is difficult to extend in the vertical direction A even if it extends in the horizontal direction.

  The ankle portion 3 that is continuously provided on the upper side of the instep portion 5 is knitted into a form that is tightly squeezed by knitting a rubber thread so that the ankle of the foot is strongly tightened and does not slip off.

The socks knitted as described above have the toe part 7 pulled upward to the instep part 5 side by the instep part 5 that is difficult to stretch in the longitudinal direction A when worn, so that the toe part 7 is slightly upward (indicated by the arrow in FIG. 1). Assist or warp in the (B direction). At that time, if the ankle portion 3 is tightly tightened to the ankle of the foot by braiding rubber thread so as not to slip off, the pulling action by the instep portion 5 is combined with the support function of the ankle portion 3. It is surely added to the toe part 7 and the toe part 7 warps more reliably.
When the toe portion 7 is warped upward in this way, it is possible to prevent the floor surface from being tripped by unevenness or a step or the like during walking. Since the knitted fabric of the sole portion 6 has an appropriate degree of stretching in the vertical and horizontal directions, it is possible to ensure ease of wearing on the foot and comfort.

  As shown in FIG. 5, it is advantageous to form the toe portion 7 in the shape of a socks that can separate the thumb bag portion 7a and the other finger bag portions 7b because the burden on the finger that warps the foot can be reduced. is there.

It is explanatory drawing which shows the formation state of the stitch by the composite knitting of normal circular knitting and reverse knitting. It is an organization chart showing an example of the knitting organization of the instep part and the sole part of the sock of the present invention.
