Description

  The present invention relates to a tubular knitted fabric obtained by improving the structure of a sock or the like having a heel corresponding to a heel of a foot.

In a tubular knitted fabric such as a sock with a heel corresponding to the heel of the foot, the knitting of the heel is knitted by rotating the needle cylinder of the automatic circular knitting machine half a half in order to give a certain curvature to the heel. is doing.
In the knitting process of the heel part, the boundary line between the linear knitted fabrics is formed as a rough line from the inner part to the outer part from the heel part to the heel part, and this line is called a gore line.

The sore gore line is usually one as shown in Patent Documents 1 and 2, and since there are few gore line stitches, the angle formed between the leg part, the upper part and the bottom part becomes shallow, When the socks were worn, there was a case where slack occurred at the boundary between the leg and the upper.
And in order to eliminate this slack, when the leg part was pulled up and worn forcibly and walked as it was, there was a fault that a leg part and a buttocks were pulled down and it fell easily.

  In addition, if such a sufficient angle does not appear in the heel part, it will not fit the heel of the human foot, and will be worn with the knitted fabric around the gore line stretched considerably, There was a feeling of being tightened.

  Accordingly, an object of the present invention is to provide socks and other tubular knitted fabrics that do not slide down and are excellent in a feeling of wearing a heel and in which slack is hardly formed as a shape in accordance with the shape of a foot.

  The present invention relates to a gore line that forms a collar part, an upper gore line that forms an upper collar part that faces upward from the start point of the gore line and is adjacent to the upper side of the collar part, and the start point with respect to the upper gore line. A cylindrical knitted fabric characterized by comprising a lower gore line that forms a lower collar portion that faces in the opposite direction and that is adjacent to the lower edge of the collar portion (device of claim 1).

  The tubular knitted fabric is specified as a sock (a device according to claim 2).

Since this invention is provided with the upper and lower collar part by the upper and lower gore lines in addition to the collar part formed by the gore line, the collar part of the tubular knitted fabric can be enlarged.
Therefore, it can be made to fit a heel, and even if a heel is not tightened and pulled down, a sliding down can be prevented.
Further, when it is necessary to reinforce the collar as a measure for improving the wear strength, in the present invention, the area of the collar is enlarged by the upper and lower collars, so that the reinforcement area can also be increased.

FIG. 1 is a side view of a sock according to the present invention. FIG. 2 is a side view of a sock (without toes) according to the present invention. FIG. 3 is a plan view of a main part of a needle cylinder of an automatic knitting machine for producing socks according to the present invention; 4 (a) to 4 (g) are views showing the manufacturing process of the sock according to the present invention and the operation state of the needle cylinder corresponding to each process.

A configuration example of a sock as a tubular knitted fabric according to the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the sock according to the present invention, when knitting the gore line G1 that appears when the heel part C of the sock S is knitted and the upper heel part D adjacent to the upper side C1 of the heel part C, is shown. And the upper gore line G2 extending upward from the start point 1 to the end 2 of the gore line G1 and the lower heel part E adjacent to the lower side C2 of the heel part C, and With respect to the upper gore line G2, a lower gore line G3 directed from the starting point 1 toward the end 4 in the opposite direction is provided.

The gore line G1 is a straight line extending from the buttock to the buttock, and if this is used as a reference line, a gore line G2 and a gore line G3 are formed so as to intersect the reference line at a substantially right angle at the starting point 1, respectively. As a whole, it has a substantially T-shape.
The width from the start point 1 to the end 2 of the gore line G2 is substantially equal to the width from the start point 1 to the end 4 of the gore line G3, and the upper collar part D and the lower collar part E are configured to have approximately the same area. Has been.

The upper heel part D and the lower heel part E expand the area of the heel part C in the vertical direction, and the enlargement absorbs the slack at the boundary J between the leg part B, the upper part F, and the bottom part H.
Accordingly, the angle formed by the leg part B, the upper part F, and the bottom part H is changed from a shallow one ("U" shape) to a deep one ("L" type).

In order to knit the sock S, rubber and fiber are supplied to an automatic circular knitting machine to produce a rubber knitted portion A, and then the fiber is fed to form a cylindrical leg B having a required length. Is knitted with "2BY1" ribs.
Next, the short bat needles 7 (see FIG. 3) in the knitting position of the length of the semicircumference (1 / 2R) with each collar part C, D and E in a half rotation state of the needle cylinder of the automatic circular knitting machine ) One by one from both ends for each reciprocation, knitting by narrowing the knitting width, reducing the knitting width, and then one short bat needle 7 raised to the non-operating position sequentially from both sides Lower to the operating position, increase the knitting width and knit to make the collars C, D and E.

When knitting the heel part D, the needle-up knitting from the start point 1 to the end 2 is set to a course of 10 to 20 courses, and the needle lowering from the end 2 to the start point 1 is set to the number 9 Set to ~ 19 courses.
When knitting the collar C, the needle raising knitting from the starting point 1 to the terminal 3 is set to 20 to 30 courses, and the needle lowering from the terminal 3 to the starting point 1 is set to 19 to 29 courses.
Further, when knitting the heel part E, the needle raising knitting from the starting point 1 to the terminal 4 is set to 10 to 20 courses, and the needle lowering from the terminal 4 to the starting point 1 is set to 9 to 19 courses. .
After creating each heel part C, D and E by flat knitting under the above settings, return to the rib of “2BY1” to knitting the upper part F and the bottom part H of the foot and reduce the size. Then, the toe portion I is knitted by flat knitting by increasing the number of stitches.

  In the case of the tubular knitted fabric shown in FIG. 2, the tubular knitted fabric is manufactured by replacing the step of the toe portion with the knitting step of the rubber knitted fabric A.

Based on FIG.3 and FIG.4, the knitting method of the sock S based on this invention is demonstrated.
Here, in FIGS. 4A to 4G, the knitting process of the socks is illustrated in the upper row in that order, and the needle bat needle 7 of the needle cylinder shown in FIG. 3 is raised and lowered in the lower row. In the figure, the thick frame indicates the state where the short bat needle 7 is lowered.
An automatic circular knitting machine of NR machine manufactured by Nagata Seiki Co., Ltd. is used as a sock knitting machine.

  Put 531 denier of 100% cotton for the front yarn, FTY30 × 75 yarn for the back yarn into each yarn feeder 5 and put the # 90 rubber yarn into the rubber insertion slot (shown in the figure). The knitting is started with rubber knitting, and the mouth rubber part A having a width of 7 centimeters and a length of 4 centimeters is tubular-knitted (see FIG. 4A).

  Next, instead of “1BY1” rubber knitting, “2BY1” rib knitting is used to form a tubular knitting having a width of 8 centimeters and a length of 16 mench (see FIG. 4B). .

Next, the short bat needles 7 at the knitting position of the width of the semicircular (1/2 R) width of the needle cylinder of the automatic circular knitting machine are placed at the 12 inactive positions immediately before knitting the heel part D. To start the half-rotation knitting of the buttocks knitting.
As shown by a thin frame in the lower part of FIG. 4 (b), 12 ends are already raised to the inoperative position (the part corresponding to the end point 2 from the starting point 1). When the short bat needles 7 that have been raised are moved one by one in the direction of the arrow from both ends to the operating position (needle lowering) to increase the knitting width and knitting, and when 12 ends at both ends have been lowered, FIG. c) As shown in the upper part, the upper collar part D is formed in the part of the end 2 to the starting point 1.

  Next, from the start point 1 to the end 3, the short bat needles 7 are raised from both ends to 23 non-operating positions in the direction of the arrows as shown in the lower part of FIG. When the knitting is narrowed, the upper half of the collar portion C is formed as shown in the upper part of FIG.

  Next, from the end 3 to the starting point 1, the short bat needles 7 in the non-operating position are sequentially lowered from both ends to the operating position one by one in the direction of the arrow in the lower part of FIG. ) When the knitting width is increased, the lower half of the collar part C is formed as shown in the upper part of FIG.

  Further, from the start point 1 to the end 4, the short bat needle 7 is raised from both ends to the non-operating position by 12 in the direction of the arrow at the bottom of FIG. As the width is narrowed, a lower collar E as shown in the upper part of FIG. 4F is completed.

Next, the upper part F is knitted into a tubular knitting having a width of 8 centimeters and a length of 13 centimeters with a rib knitting of “2BY1” and a bottom H with a flat knitting (see FIG. 4G).
Finally, the toe part I is knitted by reducing the stitches 23 from both ends (needle raising) and increasing the stitches (needle lowering).

According to the above-described sock of the present invention, the following operational effects can be obtained.
(1) An angle formed by the leg part A, the upper part F, and the bottom part H by expanding the heel part by the upper heel part D and the lower heel part E and expanding the curved part of the heel part by the enlargement. Since it becomes a deep L-shape, the entire heel is encased and the upper F and the bottom H are fixed, so that the sock can be prevented from slipping down during wearing.
(2) A supporter as a tubular knitted fabric having the same configuration can be used for elbows and knee arms, and can also be used as socks without toes.
(3) The upper heel part D and the lower heel part E enlarge the heel part C, and the enlargement absorbs the slack of the boundary J between the leg part A, the upper part F, and the bottom part H. Therefore, even if it exhibits according to the form of a leg, cylindrical knitted fabrics, such as socks which are good-looking at the time of sale, without forming slack in boundary J can be shown.
