The present invention relates to an upper and a method of weaving the same.

It is known to weave an upper by a knitting machine. In this case, in order to change the stretchability, strength, gas permeability, and the like according to the portion of the upper, it is necessary to change the type of the knitting yarn depending on the portion. Therefore, it is proposed to knit the upper by intarsia knitting and to set the boundary between the part and the part as the boundary of the intarsia (Patent Document 1 US6931762B). Furthermore, in the inlay weaving, the parts and the parts are connected by the tuck.

Represents other prior art. A weaving weave is disclosed in Patent Document 2 (JPS54-21464B) and Patent Document 3 (JPH09-111619A). At the time of the weaving of the yarn, the two knitting yarns from the two yarn feeders are superposed and the yarn loops are knitted, one knitting yarn is exposed on the front side of the knitted fabric, and the other knitting yarn is exposed on the back surface of the knitted fabric. Patent Document 2 proposes to express a pattern on a knitted fabric by weaving the yarn.

When the part of the upper is connected to the part by the tuck as in Patent Document 1, the joint is joined by the stitch of the tuck which is superposed on the double stitch of the original wrap. Here, if the tongue is connected to a portion that is easily stressed by both sides of the tongue by the tuck, there is a possibility that the tuck portion receives a strong force and the knitting yarn is broken. In particular, if the shoelace is worn on both sides of the tongue, the self-shoelace exerts a strong force on the hole through which the shoelace passes, and the hole is elongated. Moreover, if this force is applied to the tuck portion, the possibility of the knitting yarn being broken increases. Further, in addition to the weaving, the connecting portion of the tongue and the both sides thereof may be reinforced by a tape, a heat treatment or the like, but the productivity is lowered. Therefore, it is necessary to firmly connect the tongue to the joint on both sides of the knitting machine.

An object of the present invention is to provide an upper for which a tongue and a knitted fabric on both sides thereof are firmly joined to a knitting machine and a knitting method thereof.

The upper of the present invention is characterized in that it has a toe, a portion between the toe and the heel and includes a main body of the tongue, a heel, and a shoe mouth, and is cylindrical; the main body is provided with: a tongue, Covering the central portion of the instep; the right portion is located on the right side of the tongue at a right angle to the length of the instep and covers the right side of the instep to the right half of the sole; and the left portion is located on the left side of the tongue and covers The left side of the instep to the left half of the sole of the foot; The tongue and the right side portion are connected by a right-texturing region, and the right-texturing region is formed by overlapping the knitting yarn of the tongue with the knitting yarn of the right portion in a state of fixedly maintaining a positive-back relationship. The yarn weaving is woven along the circumferential direction of the upper with a knitting width of 2 or more, and the tongue and the left portion are connected by a left-engraving area, which is knitted by the tongue and the left side. The knitting yarns which are partially overlapped to form a yarn loop in a state in which the knitting yarns are fixed in a fixed-back relationship are woven in a knitting width of 2 or more in the circumferential direction of the upper.

In the present invention, the tongue and its right side portion are not joined by the tucking area but by the tucking area. Further, the yarn-adding region is formed by knitting the knitting yarn of the tongue and the knitting yarn of the right side in a state of being fixedly held in a positive-back relationship, thereby forming a knitting yarn of the yarn loop, and the knitting width is along the shoe. The circumferential direction of the surface is 2 or more. Therefore, the tongue and the right side portion are not connected by the double-sided stitch but by the surface formed by the plating area, so that the joint strength is enhanced. Similarly, the strength of the connection between the tongue and the left side portion is also enhanced.

Preferably, a row of holes is provided in the right-applied yarn region for passing the laces, and another row of holes facing the row of the holes is provided in the right-texturing region, the tongue or the right portion. And a row of holes is provided in the left-implanting region for passing the laces, and another row of holes facing the row of the holes is provided in the left-implanting region, the tongue or the left portion.

If the two rows of the opposite rows are overlapped in the middle of the two rows of the rows of holes, the opposing holes are overlapped to allow the lace to pass. Since the two laced holes are overlapped and the shoelace is passed through, the hole is not easily enlarged, and the force of the plating region can be utilized even if a strong force is applied to the hole.

The shoe opening 6 is cylindrical and has an opening 7. The heel 10 is composed of, for example, three regions 10', 10", 10"", and the direction of the warp is changed by following the main body 8 and then weaving the respective regions 10', 10", 10"". . Furthermore, the black arrow of Fig. 1 is the direction of the latitude and the hollow arrow indicates the direction of the circle.

The main body 8 includes a tongue 11 covering a central portion of the instep of the foot, a right side portion 12 covering the right half of the sole and the right side of the instep, a left portion covering the left half of the sole and the left side of the instep, and left and right sides. The left and right plating regions 14, 15 between the portions 12, 13 and the tongue 11. The tongue 11, the left and right plating regions 14, 15 and the left and right portions 12, 13 are woven into a C-shape on a horizontal knitting machine, and the C-shaped opening is located on the sole side between the left and right portions 12, 13. Further, the left and right portions 12 and 13 are joined seamlessly by joining the yarn loops on both sides of the opening of the C-shape by the joint portion 20. The bonding is performed by, for example, double-sided stitching or tucking, and the bonding method is arbitrary. Further, it may be joined by an adhesive, sewing or the like without being joined to the flat knitting machine. The upper 2 is woven, for example, seamlessly.

When the shoe is worn, a tensile force in the circumferential direction is applied to the upper 2 in accordance with the movement of the foot. Further, if a hole for passing the shoelace is provided around the tongue, the movement of the shoelace affects and the hole is elongated. On the other hand, the knitting is performed by both the knitting yarns of the left and right portions 12 and 13 and the knitting yarn of the tongue 11. As a result, the tongue 11 is joined to the left and right portions 12 and 13 by the left and right surfaces of the plating regions 14 and 15, and the strength of the joint portion is improved. Therefore, the elongation or movement of the knitted fabric can be suppressed to prevent the knitting yarn from being broken, and the elongation of the belt is not caused. Furthermore, when the yarn is woven, the two kinds of knitting yarns are fixedly held in a positive and negative relationship. The yarns are formed by overlapping in the state. Therefore, the two yarn feeders are moved on the needle bed in a positional alignment manner, and the knitting yarn exposed on the front side and the knitting yarn exposed on the back side are determined based on the relationship between the two yarn feeders before and after the needle bed.

As shown in Fig. 3, the left and right plating regions 14 and 15 are each formed in a rectangular shape, for example, and have a knitting width of 2 or more, and in the embodiment, for example, 10 stitches. The left and right plating regions 14, 15 are provided with two rows of perforated rows 16, 17 along the length direction, and the perforated rows 16, 17 are line symmetrical about the axis of symmetry 18, if bounded by the axis of symmetry 18 When the yarn regions 14, 15 are folded, the perforated rows 16, 17 overlap. The perforated rows 16, 17 may be located in the left and right plating regions 14, 15, but in order to further increase the strength, it is preferable to provide two rows of perforated rows 16, 17 in each of the plating regions 14, 15. In the case where the strength of the two rows of perforated rows 16 and 17 is insufficient, if the knitting width of the plating regions 14 and 15 is widened, four rows of perforated rows are respectively provided in each of the plating regions and folded back to four layers. In the state where the plating regions 14 and 15 are used, a firm hole row is formed.

The perforations of the perforated rows 16, 17 can be woven on a cross knitting machine. For example, when the hole with the hole is in the width direction of the latitude (the upper direction in FIG. 3) is 2 needles, if the two stitches located in the hole are moved upward and downward toward FIG. 3, respectively, it can be formed. 2-pin width with holes.

4 and 5 show the knitting of the tongue 11, the left and right plating regions 14, 15, the right portion 12, and the left portion 13. The knitting is performed on a flat knitting machine having at least a front needle bed FB and a rear needle bed BB and supplying knitting yarn from a plurality of yarn feeders 30. Here, the left side portion 13 and the left yarn application region 15 are knitted by the front needle bed FB, and the right side portion 12 and the right yarn application region 14 are knitted by the back needle bed BB, but the distribution of the front and rear needle beds may be reversed. The flat knitting machine includes, for example, a bracket having a linking pin, and the yarn feeder 30 is interlocked with the bracket with respect to a desired section by a linking pin. Further, such a yarn feeder 30 has a normal yarn feeder and is swingable by a spring or the like. Any one of the yarn feeders for intarsia can be used. Further, it is also possible to use a yarn feeder that does not move in conjunction with the carriage.

For the knitting yarn, at least three for the tongue 11 and the right portion 12 and the left portion 13 are used, and the left and right plating regions 14, 15 are knitted by two knitting yarns, respectively. Further, the knitting yarn for the right side portion 12 and the knitting yarn for the left side portion 13 are, for example, the same type of knitting yarn. When the yarn is woven, two kinds of knitting yarns are aligned and woven, one knitting yarn is exposed on the front surface of the upper 2, and the other knitting yarn is hidden on the back surface. Further, when the yarn is woven, the two yarn feeders 30 and 30 are aligned and moved.

Fig. 4 further shows the knitting range of the three yarn feeders, each of which is looped back and forth within the respective knitting range. Further, the knitting system does not surround but woven the C-shaped woven fabric of the tubular knitted fabric in a round-trip manner, and the opening of the C-shape is closed by the joint portion 20. Further, the yarn feeders of No. 3 and No. 2 are fed to the right yarn application region 14, and the left yarn application region 15 is fed from the yarn feeders of No. 1 and No. 2.

Fig. 5 is a knitting step diagram of the main body, and the knitting is sequentially performed from the step 11 of the step 1 facing downward. Step 1 indicates the initial arrangement of the three yarn feeders 30, the yarn feeder No. 1 is located on the side of the joint portion 20, and the yarn feeders numbered 2 and 3 are located on the left and right yarn application regions 14, 15 side. The left side portion 13 of the body is woven in step 2 by the yarn feeder of number 1. Then, in step 3, the yarn feeders of the numbers 1 and 2 are aligned and the left yarn application region 15 is woven. In the case of the yarn weaving, the knitting yarns from the two yarn feeders are aligned up and down to form a yarn loop. Therefore, the two yarn feeders are aligned and moved. Also, at this time, the knitting yarns from the yarn feeders of Nos. 2 and 3 are not in the left side. The knitting yarn which is caught by the needle and is fed from the yarn feeder of the number 3 in the yarn application region 15 is not caught by the needle, and a known rebound or the like is performed. Further, in the case of the self-feeding of the yarn feeder, the yarn feeder is retracted so that the knitting yarn is not caught by the needle in an unnecessary place.

When the yarn application region 15 is woven, the yarn feeder of the number 1 is cut from the knitting, and in the step 4, the left portion 11L of the tongue 11 is knitted by the yarn feeder No. 2, and the number 2 is given in the step 5 The yarn end knits the right side portion 11R of the tongue 11. Further, the right side portion 11R and the left side portion 11L are connected to the right end of the knitting width in FIG.

In step 6, the right yarn application region 14 is woven by the yarn feeder of No. 2 and the yarn feeder of No. 3. At this time, the knitting yarn of the yarn feeder of the number 1 is subjected to a process such as rebounding without being involved in knitting. In step 7, the yarn feeder of number 2 is cut from the weave, and the right side portion 12 of the body is woven by the yarn feeder of number 3.

When step 7 is completed, the configuration of the yarn feeder 30 is changed to the yarn feeder of the number 1 and the yarn feeder of the number 3 for the initial configuration of the step 1. Therefore, from the state of step 7 toward step 1, the knitting is performed in the reverse order of steps 2 to 7, and the knitting direction is reversed. In this way, the configuration of the yarn feeder 30 is restored to the initial configuration of the step 1, and one latitude can be knitted for the upper and the front. Therefore, one of the arrangement of the yarn feeder 30 in the step 1 and the yarn feeder 30 in the step 7 is the first configuration, and the other is the last configuration, and the yarn feeder 30 is disposed in the second. Changes between configurations.

Indicates a portion of the weave used to return to the state of step 1 from the state of step 7. In step 8, a perforation is formed in the left and right application yarn regions 14, 15, and the left side portion 13 of the main body is connected to the right side portion 12, and the opening of the C-shape is closed by the joint portion 20. The formation of the perforations is performed, for example, by moving the yarn loops located in the holes to the left and right and overlapping the other yarn loops.

Step 9 is such that the weaving direction of step 7 is reversed, step 10 is such that the weaving direction of step 6 is reversed, and step 11 is such that the weaving direction of step 5 is reversed. Hereinafter, if the knitting in steps 4, 3, and 2 of Fig. 5 is performed in the same order and the knitting direction is reversed in the same manner, the state of step 1 of Fig. 5 is restored. Before the knitting of Figs. 4 and 5, the tubular knitting from the starting line 5 to the vicinity of the tongue 11 is performed, and knitting is performed using, for example, one of the yarn feeders Nos. 1 and 3. After the knitting of Figs. 4 and 5, the knitting of the heel 10 and the knitting of the shoe opening 6 are performed, and knitting is performed using, for example, one of the yarn feeders Nos. 1 and 3.

Fig. 6 shows the knitting of the main body in the modification. In this modification, the left and right plating regions 14 and 15 are divided into two yarn application regions 14, 14', 15, and 15', respectively, and five yarn feeders 30 are used. The distribution of the weaving range for each of the yarn feeders is shown in Fig. 6, and is woven in such a manner as to reciprocate between the arrangement of the yarn feeders on the lower side of Fig. 6 and the arrangement of the yarn feeders on the upper side. Various designs can be dealt with by changing the thickness or strength of the knitting yarn to be used, giving a layer or changing the color.
