Description

Size adjustable socks and knitting method thereof}

The present invention relates to socks, and more specifically to size-adjustable socks that can adjust their size according to the growth of the foot.

In general, socks have performed the function of a simple foot wrap, such as physical protection of the feet from the outside, especially in the winter, a warming function by mixing appropriate materials, and a moisture absorption function to absorb sweat generated from the feet. .

Recently, as it has been discovered that foot health is closely related to physical health, special minerals such as copper, silver, and elvan are used in the yarn for knitting socks to manufacture functional socks that utilize the properties of those minerals, and magnetic components are used. A special processing method that attaches to sock products through post-processing has been developed to manufacture functional socks with anti-bacterial/odor-retaining functions, as well as functional socks using yarns with enhanced absorption functions and yarns with enhanced thermal insulation functions by modifying the physical appearance of synthetic fibers. We have been working on manufacturing functional socks, such as socks.

In addition, efforts were made to develop medical socks for the prevention and treatment of varicose veins and edema by manufacturing functional socks that apply appropriate pressure to each part of the foot and promoting blood flow by applying pressure in both directions to the body that can hold blood in the feet. I'm losing.

As a prior art of such functional socks, there is Korea Registered Utility Model No. 20-0346573 (2004. 03. 22.) “Functional Compression Long Socks,” which has a shin portion to maintain the intensity of compression for each part of the foot. In functional compression socks consisting of the calf part, the instep part, the toe part, the heel part, and the sole part, the shin part, the calf part, and the sole part are made of high-elasticity elastic yarn as rubber yarn, and the yarn is single-covered with polyurethane-based long fiber yarn. It is manufactured by knitting each part at a predetermined ratio using long fiber synthetic yarn as the inner yarn, and knitting the toe and heel parts using yarn single-covered with polyurethane long fiber yarn or long fiber synthetic yarn as the inner yarn.

In addition, there is Korea Registered Utility Model No. 20-0434219 (2006. 12. 12.) “Antibacterial socks with double-sided knitting structure or pile structure,” and the registered utility model is for the toe part of socks with double-sided knitting structure or pile structure. , Antibacterial socks that exhibit antibacterial activity more effectively and economically by knitting or forming a single-sided tissue in the above-mentioned double-sided flat structure or a piled structure in the above-described pile structure with antibacterial fibers in the sole, side, and heel area. This is provided.

However, existing prior technologies are mainly intended to supplement functions beneficial to the human body, and no technology has been developed to supplement the function of adjusting the size according to the growth of the feet in infancy, adolescence, etc.

Registered Utility Model No. 20-0346573 (functional compression socks)

The present invention knits the heel and toe parts in a hemispherical shape to be wider than the conventional heel and toe parts at regular intervals by inserting cylindrical inserts connected to the torso consisting of the instep and sole, so as to adjust to the growth of the foot. The purpose is to provide socks that can comfortably expand and adjust the size of the wearer's heel and toes, and have excellent visual design effects.

The present invention relates to a method for manufacturing socks comprising a torso, heel, and toe portion consisting of an ankle portion, an instep, and a sole portion,
The heel portion and toe portion are knitted with 2-4 cylindrical inserts connected to the body portion at regular intervals during the knitting process of knitting by forward and reverse rotation,
The insertion portion is formed of relatively more elastic thread or highly elastic tissue than the heel portion and the toe portion, so that the size can be adjusted independently according to the growth of the foot.

Additionally, the insertion part may be characterized by using colored yarn.

The size-adjustable socks of the present invention are knitted with cylindrical inserts connected to the torso consisting of the instep and sole at regular intervals in the heel and toe parts, which are knitted in a hemispherical shape. And the toe part can be formed wider, which can have the effect of wrapping the wearer's heel and toe part more comfortably.

In addition, the size-adjustable socks of the present invention have the effect of expressing various designs by doubling the elasticity of the heel and toe parts by using highly elastic yarn or colored yarn in the cylindrical insert part and pursuing an aesthetic design. there is.

Figure 4 is a plan view showing a sock according to another embodiment of the present invention

The socks according to one embodiment of the present invention are intended to complement the function of adjusting the size according to the size of the foot, and there is no significant difference in structure compared to existing socks except for the heel and toe parts.

As shown in Figure 1, most all socks are in the form of a wrap that completely covers the foot when worn, and therefore have a sole portion 10 that faces the sole of the foot and an instep portion 20 that covers the instep. On one side of the instep portion 20, an ankle portion 30 capable of covering the ankle portion is formed integrally, and at the top of the ankle portion 30 to prevent the ankle portion 30 of the sock from slipping down as necessary. An ankle tightening portion 40 may be formed, and a heel portion 50 and a toe portion 60 may be formed on the front and rear surfaces of the sole and instep, respectively. In other words, the majority of all socks have been manufactured with this structure. The present invention is not at all different from the structure of such conventional socks. However, as shown in Figure 2, the present invention realizes the structure of the conventional sock as is, while pursuing stability of form by adding relatively highly elastic insertion portions 70 to the heel and toe portions at regular intervals and knitting them. It has a major feature in that it can be knitted wider than the conventional heel and toe parts, and can be knitted in a form that can increase in size depending on the size of the wearer's foot.

These socks are knitted by a knitting machine such as a circular knitting machine. A circular knitting machine is a machine that knits by rotating needles arranged in a circle, and can make tubular knitted fabrics by forming knitting loops using knitting needles. Circular knitting machines usually have a cylindrical needle cylinder installed on the outside of the cylinder shaft that rotates by a motor, and a plurality of slots are arranged at predetermined intervals along the inner edge of the needle cylinder. The needles are inserted into each slot to raise and lower, and each needle A sinker that is located between the and needles and lowers the yarn to form a loop is arranged at a right angle to the needle and is configured to move back and forth. In a circular knitting machine, knitting is accomplished with each needle moving up and down as the needle cylinder rotates by the cylinder shaft, and at the same time, the sinker holds the yarn. With the yarn inserted into multiple needles, it sequentially goes down and then up again, creating loops continuously as each sinker moves forward and backward, knitting cylindrical knitted fabrics such as socks, mufflers, overstraps, and toshes.

Hereinafter, a method of knitting socks according to the present invention will be described with reference to the attached Figure 2.

When knitting a general cylindrical sock, a cylinder equipped with needles rotates continuously in one direction to knit the yarn. Here, the toe part is an area that essentially surrounds or protects the toes of the user's feet when the sock is worn, The heel portion is an area that essentially surrounds or protects the heel of the user's foot when the sock is worn, and typically has a hemispherical shape.

Accordingly, in a general sock knitting method, the ankle portion 30 and the instep and sole portions 10 and 20 of the sock are knitted into a tubular body according to the usual method, but the heel portion 50 and the toe portion ( 60) is not cylindrical, but has a shape that surrounds only the heel or toe, which is part of the foot, that is, a hemisphere, so the cylinder does not rotate continuously 360 degrees, but rotates forward (clockwise) and counterclockwise (half) within a certain angle range. Knitting is repeated in a clockwise direction.

However, when the heel and toe parts knitted in this way were knitted large and wide as needed, the shape was not stable and became distorted or wrinkled, making it difficult to easily change the structure.

Accordingly, the heel portion 50 of the sock according to the present invention is knitted by inserting a process of knitting into a barrel shape in the middle of the knitting process while repeating general forward and reverse rotation. That is, knitting is repeated as necessary in the following order: heel knitting process by forward and reverse rotation - cylindrical knitting process - heel knitting process by forward and reverse rotation - cylindrical knitting process.

At this time, it is desirable to use yarn with higher elasticity than other parts in the tubular knitting process inserted into the heel knitting process or to knit with highly elastic tissue so that the size can be easily varied according to the elasticity.

In addition, it is desirable to pursue an aesthetic design using colored yarn in the tubular knitting process inserted into the heel knitting process. At this time, from a design perspective, it is more desirable to carry out the tubular knitting process not only as an intermediate process inserted into the heel knitting process, but also to a certain width before and after the heel knitting process.

The toe part of the sock according to the present invention can be divided into a general case in which the toe part of the sock is knitted while repeating forward and reverse rotation within a certain angle range, like the heel part, and a case in which the instep and sole parts of the sock extend to the toe part and are knitted in a tubular shape. there is.

When knitting while repeating forward and reverse rotation within a certain angle range, knitting may be done in the same manner as the heel part.

In addition, when the instep and sole of the sock extend to the toe and are knitted in a tubular shape, the knitting process is completed without sewing. In this case, when knitting the part corresponding to the toe, it is relatively elastic. The knitting part is made by inserting an insert made of high thread and highly elastic tissue in the middle, and the parts that cannot be sewn together are then completed by joint sewing using a separate sewing machine.

Ultimately, socks completed according to the manufacturing method of size-adjustable socks according to a preferred embodiment of the present invention have a wider heel and toe area than conventional socks, so that they can comfortably wrap the wearer's heel and toe area. It is expected to have advantages such as the ability to pursue diversification in terms of design.
