Description

  The present invention relates to a shoe upper and a knitting method thereof.

  It is known to knit a shoe upper with a knitting machine. In this case, in order to change stretchability, strength, air permeability, etc. depending on the part of the shoe upper, it is necessary to change the type of knitting yarn depending on the part. Therefore, it has been proposed that a shoe upper is knitted by intarsia knitting so that the boundary between the parts is the boundary of the intarsia (Patent Document 1 US6931762B). In the intarsia knitting, the part and the part are connected by tack.

  Other prior art is shown. Patent Document 2 (JPS54-21464B) and Patent Document 3 (JPH09-111619A) disclose plating knitting. In plating knitting, two knitting yarns from two yarn feeders are overlapped to form a stitch row, with one knitting yarn appearing on the surface of the knitted fabric and the other knitting yarn appearing on the back surface of the knitted fabric. Patent Document 2 proposes expressing a pattern on a knitted fabric by plating knitting. Patent Document 3 proposes that an intarsia pattern is knitted by switching the knitting yarn appearing on the front surface of the knitted fabric but not switching the knitting yarn appearing on the back surface.

US6931762B JPS54-21464B JPH09-111619A

  As in Patent Document 1, when a portion of a shoe upper is connected by tack, the connection portion is joined by a double stitch where the eyes of the tack overlap the original stitch. Here, if a portion where force is easily applied, such as the tongue, is connected with a tack, a strong force may be applied to the tack portion and the knitting yarn may be broken. In particular, when a shoelace is passed through both sides of the tongue, a strong force is applied from the shoelace to the hole through which the shoelace passes, and the strap hole extends. Further, when this force is applied to the tack portion, the possibility that the knitting yarn is broken increases. In addition, although the connection part of a tongue and its both sides may be reinforced with an adhesive tape, heat processing, etc. separately from knitting, productivity falls. Therefore, it is necessary to firmly connect the connecting portion between the tongue and both sides thereof on the knitting machine.

  An object of the present invention is to provide a shoe upper in which a tongue and a knitted fabric on both sides thereof are firmly connected on a knitting machine, and a knitting method thereof.

The shoe upper of this invention comprises a toe, a torso and a torso and a torso including a tongue, a heel, a foot, and a cylindrical shape.
The torso is on the right side of the tongue along the direction perpendicular to the longitudinal direction of the upper and on the right side of the sole, covering the right half of the sole, and on the left side of the tongue. With the left side covering the left half of the sole from the left side of the back,
The knitting yarn of the tongue and the knitting yarn of the right side are overlapped while maintaining a constant relationship between the front and back, and the right plating region where two or more stitches continue along the circumferential direction of the shoe upper, Part is connected,
In addition, the knitting yarn of the tongue and the knitting yarn of the left side portion are overlapped with the knitting yarn being kept in a constant relationship between the front and back. And the left side portion are connected.

  In the present invention, the tongue and the right side portion thereof are connected not by the tack but by the plating area. The plating area is composed of stitches in which the knitting yarn of the tongue and the knitting yarn on the right side are overlapped while maintaining a constant relationship between the front and back, and the width is two or more along the circumferential direction of the shoe upper. is there. For this reason, the tongue and the right side portion are connected not by the overlapped line but by the surface formed by the plating region, and the connection strength is increased. Similarly, the connection strength between the tongue and the left side portion also increases.

Preferably, a first string hole row for passing shoelaces is provided in the right plating region, and a second string hole row facing the first string hole row is provided in the right plating region, Or on the right side,
Left plating region, the third string rows of apertures for passing the shoelace is provided a row, and a fourth cord hole array which faces the third string hole row, left plating region, Tan or left, It is provided in the part.

  When folded in the middle of the two string hole rows so as to overlap the two string hole rows facing each other, the opposite string holes overlap to allow the shoelaces to pass therethrough. Since two lace holes are overlapped and a shoelace is passed, the lace hole is difficult to expand, and even if a strong force is applied to the lace hole, the force can be supported in the plating region.

This invention is a method of knitting a cylindrical shoe upper on a flat knitting machine having at least a pair of needle beds in the front and rear,
Start knitting from the toe or the mouth, knitting the toe, the trunk between the toe and the heel and including the tongue, the heel, and the mouth.
In the knitting of the trunk, the tongue that covers the center of the upper,

The left side of the tongue and covering the left half of the sole from the left side of the upper,
A knitting yarn that connects the tongue and the right side, and the knitting yarn of the tongue and the knitting yarn of the right side are overlapped while maintaining a constant relationship between the front and back, forming a stitch, along the circumferential direction of the shoe upper A right plating area knitted with a stitch width of 2 stitches or more,
A knitting yarn that connects the tongue and the left side part, and the knitting yarn of the tongue and the knitting yarn of the left side part are overlapped while maintaining a constant relationship between the front and back sides, forming a stitch, along the circumferential direction of the shoe upper Left plating area knitted with two or more stitch widths,
And organize
In the body knitting, the right part, the right plating area, the tongue, the left plating area, the left part, the left part, the left part, the left part The step of knitting in the order of the plating knitting of the plating area, the knitting of the tongue, the plating knitting of the right plating area, and the knitting of the right side portion is alternately repeated.

  In this way, it is possible to knitting a shoe upper in which a tongue is connected to the left and right portions thereof at the plating area. In this shoe upper, the connection strength between the tongue and the left and right parts is increased.

Preferably, in the right plating region, a first string hole row for passing shoelaces is formed on a single flat knitting machine, and a second string hole row facing the first string hole row is plating region, formed by flat knitting machine Tan or right part, left plating area, formed by the third cord hole row a row flat knitting machine for passing the shoelace, and third A fourth string hole array facing the string hole array is formed on the left plating area, tongue, or left side portion on the flat knitting machine. If it does in this way, the string hole and plating area which can bear the force added from a shoelace can be knitted on a flat knitting machine.

  In the present invention, the trunk composed of the tongue and the periphery thereof is knitted into a C shape by C knitting, and a C-shaped opening is formed on the sole. Preferably, the C-shaped opening is closed by a double stitch, a tack or the like, and the right side portion and the left side portion of the body are joined on the flat knitting machine.

In the arrangement of each part on the needle bed of the flat knitting machine,
・ The right part and the left part face each other on the front and back needle beds,
・ The right plating area and the left plating area face each other on the front and back needle beds,
・ The right half and the left half of the tongue face each other on the front and back needle beds.
Then, the leftmost stitch of the right half of the tongue is knitted so as to be connected to the rightmost stitch of the left half of the tongue.

For example, it is assumed that the knitting yarn of the tongue is different from the knitting yarn of the right side portion and the left side portion. Since the knitting is C knitting, there are at least three yarn feeders, one for the tongue, one for the right side, and one for the left side. With the center part of the tongue as one end of the knitting width and the center part of the sole as the other end,
The arrangement A in which the yarn feeder of the right side is at the other end of the knitting width, the yarn feeder of the left side and the yarn feeder of the tongue are near the boundary between the right side and the left side and the left and right plating areas;
・ The left side yarn feeder is at the other end of the knitting width, and the right side yarn feeder and tongue yarn feeder are between the right side and left side and the arrangement B near the boundary between the left and right plating areas. Are repeated alternately.

And

  In the following, an optimum embodiment for carrying out the invention will be shown.

  1 to 6 show an embodiment and its modification, FIG. 1 shows a state in which a shoe upper 2 is folded flat, and FIG. 2 shows an expanded state. 4 is a toe, 6 is a mouth, 8 is a torso that wraps the back and sides of the foot and the sole, and the toes 4, torso 8 and the mouth 6 are all cylindrical. 10 is a heel between the mouth 6 and the trunk 8, and is formed by turning back. A shoe sole (not shown) is attached to the bottom of the shoe upper 2.

  5 is a set-up line where knitting starts, and S and S ′ are knitted from the toe 4 to the toe 6 in the directions of the white arrows in FIGS. 1 and 2, but from the toe 6 to the toe 4. You may organize it. The mouth 6 is cylindrical and has an opening 7. The saddle 10 is made up of, for example, three regions 10 ′, 10 ″, 10 ′ ″. To change. In FIG. 1, the black arrow indicates the course direction, and the white arrow indicates the wale direction.

  The torso 8 includes a tongue 11 that covers the center of the instep, a right side 12 that covers the right half of the sole and the right side of the back, a left side 13 that covers the left half of the sole and the left side of the back, and left and right The left and right plating regions 14 and 15 between the portions 12 and 13 and the tongue 11 are included. The tongue 11, the left and right plating regions 14, 15 and the left and right parts 12, 13 are knitted in a C shape on the flat knitting machine, and the C-shaped opening is on the sole side between the left and right parts 12, 13. . Then, the stitches on both sides of the C-shaped opening are joined by the joining portion 20, and the left and right portions 12 and 13 are joined without sewing. Joining is performed by, for example, double stitching or tacking, but the joining method is arbitrary. Moreover, you may join by an adhesive agent, sewing, etc., without joining on a flat knitting machine. The shoe upper 2 is knitted without sewing, for example.

  When the shoes are worn, a pulling force along the circumferential direction is applied to the shoe upper 2 according to the movement of the foot. Furthermore, if a lace hole through which the shoelace passes is provided around the tongue, the movement of the lace affects the lace and the lace hole extends. On the other hand, plating knitting is performed with both the knitting yarns of the left and right portions 12 and 13 and the knitting yarn of the tongue 11. Then, the tongue 11 is joined to the left and right portions 12 and 13 on the surface formed by the left and right plating regions 14 and 15, and the strength of the joined portion is increased. For this reason, the stretch and movement of the knitted fabric can be suppressed, the knitting yarn can be prevented from being cut, and the string hole is not stretched. In plating knitting, two types of knitting yarns are overlapped while maintaining a constant relationship between the front and back surfaces to form stitches. For this reason, the two yarn feeders are moved on the needle bed so that their positions are aligned, and the knitting yarn appearing on the front side and the knitting yarn appearing on the back side are determined by 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 both rectangular, for example, and the knitting width is 2 stitches or more, and 10 stitches in the embodiment. The left and right plating regions 14 and 15 are provided with two string hole rows 16 and 17 along the longitudinal direction. The string hole rows 16 and 17 are line symmetric with respect to the symmetry axis 18, and the symmetry axis 18 is the boundary. When the plating regions 14 and 15 are folded, the string hole rows 16 and 17 overlap each other. One of the string hole rows 16 and 17 may be in the left and right plating regions 14 and 15, but in order to further increase the strength, each of the plating regions 14 and 15 has two string hole rows 16 and 17 respectively. Is preferably provided. If the strength of the two string hole arrays 16 and 17 is insufficient, the knitting width of the plating areas 14 and 15 is widened, and four string hole arrays are provided in each of the plating areas, and folded back to form the plating area. When 14 and 15 are used in a four-layer state, a strong string hole array is obtained.

  The string holes of the string hole rows 16 and 17 can be knitted on a flat knitting machine. For example, when the string hole has a second width along the course direction (vertical direction in FIG. 3), when the second stitch located in the string hole is transferred to the top and the bottom of FIG. Can be formed.

  4 and 5 show the knitting of the tongue 11, the left and right plating regions 14, 15, the right side portion 12, and the left side portion 13. FIG. Knitting is performed on a flat knitting machine that includes at least a front needle bed FB and a rear needle bed BB and feeds knitting yarns from a plurality of yarn feeders 30. Here, the left portion 13 and the left plating region 15 are knitted with the front needle bed FB, and the right portion 12 and the right plating region 14 are knitted with the rear needle bed BB. good. The flat knitting machine includes, for example, a carriage having entraining pins, and the yarn feeder 30 is entrained in the carriage with respect to a desired section by the entraining pins. The yarn feeder 30 includes a normal yarn feeder and an intarsia yarn feeder that can be swung by a spring or the like. Further, a yarn feeder that is self-propelled instead of being taken along the carriage may be used.

  At least three knitting yarns for the tongue 11, the right portion 12, and the left portion 13 are used, and the left and right plating regions 14 and 15 are knitted with two knitting yarns each. The knitting yarn for the right portion 12 and the knitting yarn for the left portion 13 are, for example, the same type of knitting yarn. In the plating knitting, two types of knitting yarns are knitted together, one knitting yarn appears on the surface of the shoe upper 2, and the other knitting yarn hides on the back surface. In the plating knitting, the two yarn feeders 30 and 30 are moved together.

  FIG. 4 shows the assignment of the yarn feeder 30 to the knitting width W. The yarn feeder No. 1 is assigned to the left portion 13, the yarn feeder No. 3 is assigned to the right portion 12, and the yarn feeder No. 2 is assigned to the tongue 11. FIG. 4 further shows the knitting ranges of three yarn feeders, and each yarn feeder reciprocates within the respective knitting ranges. Further, the knitting is C knitting in which the tubular knitted fabric is knitted in a reciprocating manner instead of a round, and the C-shaped opening is closed by the joint portion 20. The right plating region 14 is fed from the number 3 and number 2 yarn feeders, and the left plating region 15 is fed from the number 1 and number 2 yarn feeders.

  FIG. 5 is a knitting process diagram of the trunk. Knitting is performed in the order from the lower 1) to the upper 11). 1) shows the initial arrangement of the three yarn feeders 30, where the number 1 yarn feeder is on the joint 20 side and the number 2 and 3 yarn feeders are on the left and right plating regions 14, 15 side. In 2), the left side portion 13 of the body is knitted by the yarn feeder No.1. Subsequently, in 3), the left plating region 15 is plated and knitted with the yarn feeders of numbers 1 and 2 aligned. In plating knitting, the knitting yarns from the two yarn feeders are aligned vertically to form a stitch row, and therefore the two yarn feeders are aligned and moved. Also, at this time, the knitting yarn from the yarn feeders of Nos. 2 and 3 is not caught by the needle at the left side portion 13, and the knitting yarn from the yarn feeder of No. 3 is not caught by the needles in the plating region 15 is known. Processing such as kicking back. In the case of a self-propelled yarn feeder, the yarn feeder is retracted so that the knitting yarn is not caught by the needle in an unnecessary place.

  When the plating area 15 is knitted, the yarn feeder with the number 1 is separated from the knitting, the left portion 11L of the tongue 11 is knitted with the yarn feeder with the number 2 in 4), and the right portion 11R of the tongue 11 is knitted in 5) in FIG. Knit with yarn feeder number 2. The right portion 11R and the left portion 11L are connected at the right end of the knitting width in FIG.

  In 6) of FIG. 5, the right plating area 14 is plated by the yarn feeder No. 2 and the yarn feeder No. 3. At this time, processing such as kick back is performed so that the knitting yarn at the yarn feeder of No. 1 is not involved in the knitting. In 7) of FIG. 5, the yarn feeder with the number 2 is separated from the knitting, and the right portion 12 of the trunk is knitted with the yarn feeder with the number 3.

  When the processing of 7) in FIG. 5 is completed, the arrangement of the yarn feeders 30 is obtained by replacing the number 1 yarn feeder and the number 3 yarn feeder with respect to the first arrangement of 1). Therefore, from the state 7) to the state 1), the knitting is performed in the reverse order of 2) to 7) and with the knitting direction reversed. Then, the arrangement of the yarn feeder 30 returns to the initial arrangement of 1), and the shoe upper can be knitted for one course each before and after. Therefore, one of the arrangement of the yarn feeder 30 in 1) and the arrangement of the yarn feeder 30 in 7) is the first arrangement, the other is the last arrangement, and the arrangement of the yarn feeder 30 is between these two arrangements. Change.

  A part of the knitting for returning from the state 7) to the state 1) of FIG. 5 is shown. 5), string holes are formed in the left and right plating regions 14 and 15, the left side portion 13 and the right side portion 12 of the trunk are connected, and the C-shaped opening is closed at the joint portion 20. The string hole is formed, for example, by moving a stitch located in the hole to the left and right and overlapping the other stitch.

  9) in FIG. 5 is the reverse of the knitting direction of 7), 10) is the reverse of the knitting direction of 6), and 11) of FIG. 5 is the reverse of the knitting direction of 5). Similarly, when the knitting of 4), 3) and 2) in FIG. 5 is executed in this order and with the knitting direction reversed, the state returns to 1) in FIG. Before the knitting shown in FIGS. 4 and 5, there is a cylindrical knitting from the start line 5 to the front of the tongue 11, and for example, knitting is performed using one of the number 1 and 3 yarn feeders. After the knitting shown in FIGS. 4 and 5, there are a knitting of the heel 10 and a knitting for the wearer mouth 6, for example, using one of the yarn feeders of numbers 1 and 3.

  FIG. 6 shows the knitting of the trunk in the modified example. In this modification, the left and right plating regions 14 and 15 are each divided into two plating regions 14, 14 ′, 15 and 15 ′, and accordingly, five yarn feeders 30 are used. The assignment of the knitting range to each yarn feeder is shown in FIG. 6, and knitting is performed so as to reciprocate between the arrangement of the lower yarn feeder in FIG. 6 and the arrangement of the upper yarn feeder. Various designs can be accommodated by changing the thickness and strength of the knitting yarn to be used in stages or by changing the color and the like.
