Description

  The present invention relates to a sock with a low mouth knitting position so that the worn sock is not excessively seen outside the shoe when wearing a low (thin) shoe such as sneakers ( Such socks are referred to as short socks, cover socks, foot covers, etc.) and a method for manufacturing the socks.

  A sock (hereinafter referred to as a short sock) having a low knitting position at the mouth part and a large mouth part (hereinafter referred to as short socks) is manufactured by cutting and sewing a sock [for example, JP 2011-26716 A (Patent Document 1)] And knitting with a circular sock knitting machine [for example, JP 2011-52335 A (Patent Document 2)]. However, in the knitting method as disclosed in Patent Document 2, the size of the wearing mouth portion (mouth rubber portion 2) is determined by the number of needles, the number of gauges, etc. provided in the cylinder of the circular knitting machine. Therefore, it is difficult to knit socks having wide open mouth portions.

  The applicant of the present application previously divided the foot part into two parts, the heel side and the foot side, in Japanese Patent No. 3700148 (Patent Document 3), and the heel part knitted following the knitting of the heel side mouth part, A sock has been proposed which has a foot knitted following the foot knitting at the foot side and an extended knitted fabric portion interposed between the heel knitted fabric and the foot knitted fabric.

  On the other hand, in a short sock with a wide open mouth, there is a problem that when the wearer walks, the heel part of the sock is pulled by the toe part and is displaced, and the sock is easily removed.

  In order to solve such a problem, it is possible to attach a sheet having a non-slip function to the inside of the sock's heel part (Japanese Patent Laid-Open No. 9-59804 (Patent Document 4)) and Japanese Utility Model Laid-Open No. 6-51207 (Patent). It is proposed in the literature 5). Japanese Laid-Open Patent Publication No. 11-335905 (Patent Document 6) proposes that a non-slip yarn is knitted.

JP 2011-26716 A JP 2011-52335 A Japanese Patent No. 3700148 JP-A-9-59804 Japanese Utility Model Publication No. 6-51207 JP 11-335905 A

  The proposals of Patent Document 4 and Patent Document 5 for making it difficult to remove the short socks require that a sheet having a non-slip function is attached to the inside of the sock's heel in a separate process after knitting the sock. There is a problem that the socks are expensive and socks are expensive.

  Also, the sock of Patent Document 6 has an anti-slip effect in which polyurethane elastic yarns are knitted in a ratio of once every four courses when two knitted parts are knitted. I am aiming. However, since the sock of patent document 6 is completed by cutting and sewing, the whole sock does not fit a wearer exactly. Therefore, the polyurethane elastic yarn in the heel portion of the sock does not adhere to the wearer's heel, and the contact area between the polyurethane elastic yarn and the wearer's heel is small, and the anti-slip effect is small. The problem of easy removal during walking has not been solved.

  The present invention is a sock that can be manufactured without using a cutting / sewing process in view of the above points, and is a sock (short socks) that has a wide opening and appears to the instep of the wearer. The object is to provide socks that do not take off when walking with socks. Moreover, it aims at providing the method of knitting the socks.

  The present invention comprises a buttock that is divided into a front and a back and knitted following the knitting of the heel side lip, a foot that is knitted following the foot side lip, and a buttock knitted fabric. In a sock having an extended knitted fabric portion provided between a foot knitted fabric and a toe portion, the upper ¼ or more of the back side portion of the heel portion and the extended knitted fabric portion are highly elastic elastic yarns The above-mentioned object is achieved by a sock characterized by being knitted to form a stitch loop.

  The high stretch elastic yarn is preferably a 90-110th rubber yarn. Alternatively, the high stretch elastic yarn is preferably a double covering yarn having a polyurethane elastic yarn of 70 to 180 denier as a core yarn.

  Furthermore, in the sock, it is preferable that a highly elastic elastic thread is inserted into a ring-shaped portion surrounding the instep and the sole, which is knitted on the foot side side and the mouth portion on the foot side.

  Further, the present invention selects an appropriate number of knitting needles capable of knitting the heel pocket in a circular sock knitting machine, and knitting the heel side cuff with the selected knitting needle by reciprocating rotation of a cylinder of the knitting machine. Then, the first trapezoid knitted fabric is knitted while gradually decreasing the knitting needles involved in knitting among the knitting needles, and then the second trapezoid knitted fabric is knitted while gradually increasing the knitting needles involved in knitting. Forming a heel pocket, and using only the knitting needles used for knitting the heel pocket, knitting the extended knitted fabric portion which becomes the sole by reciprocating rotation of the cylinder of the knitting machine, and then the cylinder of the knitting machine in one direction Knitting the first trapezoid knitted fabric when knitting the first trapezoid knitted fabric in the sock knitting method of knitting the foot-side wear mouth while rotating to the next, and then knitting the foot portion and the toe portion From the first trapezoid knitted fabric Until knitting at least 1/4 of the number of courses, use high stretch elastic yarns so that the high stretch elastic yarns form a stitch loop, and also when knitting the extended knitted fabric part The above object is achieved by a sock knitting method characterized in that a high stretch elastic yarn is used so that the high stretch elastic yarn forms a stitch loop.

  In the knitting method, it is preferable that the ring-shaped portion surrounding the instep and the sole, which is knitted following the foot side side mouth portion, is knitted while inserting the highly elastic elastic yarn.

  According to the present invention, in a sock having a sock mouth part divided at the front and back, and having a heel part, a foot part, and an extended knitted fabric part provided between the two parts, a back side part of the heel part The upper 1/4 and the extended knitted fabric part are knitted so that the high elastic elastic yarn forms a stitch loop. In the knitted product, the stitch loop of the high elastic elastic yarn shrinks and becomes smaller. When the socks are worn, the knitted loops of the highly stretchable elastic yarn that has been shrunk are put on in an extended state. The large stretch performance of the high-stretch elastic yarn stitch loop makes it possible to fit the sock's mouth and heel closely to the wearer's foot and prevent the sock from shifting.

  Furthermore, the extended knitted fabric part formed by the stitch loop of the high elastic elastic yarn hits the wearer's arch and absorbs the movement of the vertical arch of the wearer's foot during walking, so that Reduce the action of pulling the part downward. Thereby, the shift | offset | difference of the buttocks of socks at the time of a walk can be prevented further.

  It is preferable to use a high-elastic elastic yarn as a 90 to 110th rubber yarn or a double covering yarn using a 70 to 180 denier polyurethane elastic yarn as a core yarn. If the thickness of the yarn is too thick, knitting on the knitting machine becomes difficult. Conversely, if the yarn is too thin, the desired effect of making it difficult to take off the socks cannot be obtained.

  In addition, when a highly elastic elastic thread is inserted into the foot-shaped side of the mouth and the ring-shaped part surrounding the instep and the sole that is knitted, the foot-side side of the mouth, the instep and the foot The ring-shaped part surrounding the back fits the wearer's foot. And since the highly elastic elastic yarn surrounds the socks' mouth circumference (that is, the back side portion, the extended knitted fabric portion, and the foot side side of the mouth portion), the mouth portion of the socks opens greatly and appears to the instep of the wearer. Even in such a sock, the sock's mouth is in close contact with the wearer's foot over the entire circumference.

It is a schematic perspective view of one Example of the sock of this invention. It is a design drawing which shows the process of knitting the sock of the embodiment of the present invention shown in FIG. It is a design figure which shows another knitting process in the knitting method of the sock of this invention. It is a design figure which shows the other knitting process in the knitting method of this invention. It is a design drawing which shows another knitting process in the knitting method of the present invention.

  Hereinafter, the present invention will be described in detail based on illustrated embodiments.

  The sock 1 of the present invention is a circular sock knitting machine with a heel side wear mouth portion 2, a heel portion (heel pocket) 4, an extended knitted fabric portion 5, a foot portion side wear mouth portion 6, a foot portion 7, a toe portion (toe portion) Pocket) 8 in order. The sock 1 according to the present invention has a mouth portion divided into front and rear portions, and an extended knitted fabric portion 5 is provided between the heel side mouth portion 2 and the foot portion side mouth portion 6 so that the mouth portion is large. A sock (short socks) that opens and appears to the wearer's instep.

  In the embodiment shown in FIG. 1, the heel side wearing mouth 2 is a double knitted knitted knitted cross section in the wale direction, and the connecting portion 3 is provided between the heel 4. Further, the toe portion 8 is beaten with the foot portion 7 on the back side (the beat portion is indicated by reference numeral 9). A dotted line in FIG. 1 represents a gore line generated by increase / decrease of the knitting needles acting at the time of knitting.

  FIG. 2 is a design diagram for knitting the sock shown in FIG. 1. The horizontal width of FIG. 2 is shown by developing one round of the circular knitting machine. FC indicates the front center of the sock.

  The sock 1 of the present invention starts knitting from the heel side mouth part 2. Of the needles inserted in the cylinder of the circular knitting machine, select the needle on the heel side in the range of 60 to 80% of the total number of needles (the heel pocket will be smaller if the number of needles is small), and rotate the cylinder back and forth. Start organizing. In the first course, the selected needle is used every other wale, and the second course starts knitting in either the forward or reverse rotation direction. .

  After that, without changing the knitting area, knitting an arbitrary number of courses by changing the direction of rotation for each course with one wale needle, knitting a predetermined number of courses, returning to knitting with all the selected needles, and holding one wale every other By binding the loop of the second course, the heel side mouth part 2 as shown in FIG. 1 is knitted to form a ring-shaped (that is, the cross section in the wale direction is a ring-shaped) stop knitting.

  Next, in the embodiment shown in FIG. 2, before entering the knitting of the heel part 4, the heel side wear mouth part 2 is continued, and a predetermined number of courses are knitted with all the needles in the selected range as the connecting part 3.

  Next, the knitting of the buttocks (heel pocket) 4 is started. In the subsequent courses, the first trapezoid knitted fabric 41 is knitted by reducing the knitting width at both ends of the knitted fabric for each arbitrary course, and thereafter, the knitting width is increased and the top side of the first trapezoid knitted fabric 41 is the same. Two trapezoid knitted fabrics 42 are knitted until the first course width of the first trapezoid knitted fabric 41 becomes equal. When the second trapezoid knitted fabric 42 is knitted, the bag-shaped heel pocket 4 is formed by knitting the loop at the course end portion of the first trapezoid knitted fabric 41 at the traverse end thereof. At the time of the knitting, the tip positions of the acute angle portions of the triangles formed by the both ends of the bases of the trapezoidal knitted fabrics 41 and 42 are not necessarily matched. For example, the length of the base of the first trapezoidal knitted fabric 41 is The knitting which is smaller than the length of the bottom side of the second trapezoidal knitted fabric 42 may be used.

  Next, the knitting of the extended knitted fabric portion 5 is started. The knitting start course of the extended knitted fabric portion 5 is knitted with the same needle as the final course of the bottom side of the second trapezoid knitted fabric 42. That is, when the final course of the second trapezoidal knitted fabric 42 is knitted to the end, the cylinder is reversed and the next course is knitted with the same number of wales. This inversion is repeated to perform a predetermined number of courses. The folded-back portions (ear knitting portions 51) at both ends of the extended knitted fabric portion 5 have the same configuration as so-called ear knitting at both side ends of the knitted fabric knitted by the flat knitting machine.

  If the number of courses of the extended knitted fabric portion 5 having the ear knitting portions 51 at both ends is increased, the length from the heel portion 4 of the sock to the tip of the toe portion (toe pocket) 8 is increased, that is, the opening of the mouth portion. Can be increased.

  After the final course of the extended knitted fabric portion 5 is knitted, the needle that has been at the rest position is returned to the knitting position, and then the knitting of the foot side wear mouth 6 is started. The knitting of the foot part side mouth part 6 is performed by rotating the cylinder in one direction (forward rotation) using all the needles of the knitting machine cylinder. As a result, the end (foot part side mouth part) 61 where knitting was started by the needle that was in the rest position when the heel side mouth part 2 was knitted, and the ring that surrounds the instep and sole that were subsequently knitted. The foot part side mouth part 6 which consists of the shape part 62 is knitted.

  Next, the knitted fabric of the foot portion 7 is knitted by rotating the cylinder in one direction (forward rotation) using all the needles of the knitting machine cylinder. By forming this tubular knitting with an arbitrary course, the knitting of the foot portion 7 including the instep portion and the sole portion is performed. The knitting of the foot portion 7 is the same as that of the conventional socks, and the toe pocket 8 of the toe portion is subsequently knitted by the conventional method following the foot portion 7.

  In the embodiment shown in FIG. 2, the toe pocket 8 is knitted from the sole side portion 81, and the knitting is finished at the instep side portion 82. The opening between the instep side portion 82 and the foot 7 on the instep side is closed by an appropriate means such as linking (see reference numeral 9 in FIG. 1). In the embodiment shown in FIG. 2, the opening is formed on the instep side. In FIG.

  The sock of the present invention is characterized by the use of yarn during knitting and the way of knitting. The upper ¼ or more portion 4a and the extended knitted fabric portion 5 of the back side portion of the heel portion 4 (that is, the first trapezoidal knitted fabric 41) and the extended knitted fabric portion 5 use a high stretch elastic yarn as a surface yarn, and a high stretch elastic yarn Is knitted to form a stitch loop. In order to improve the adhesion between the feet (people wearing socks) and the feet of the wearer and these portions 4a and 5, no backing thread is used when knitting these portions.

  The high stretch elastic yarn in the present invention is a yarn that has high stretchability and requires a large force when stretching the yarn as compared with a normal knitting yarn. Specifically, it is preferable to use a 90-110th rubber thread, or a 70-180 denier polyurethane core thread that is double-covered with a covering thread made of 70-75 denier nylon, polyester, or rayon.

  In addition, the foot side foot opening 6 inserts high stretch elastic yarns every other stitch (no loop-like stitches are formed) into a plain knitted fabric with normal knitting yarn as the front yarn. As a result, the knitted fabric looks like a tuck knitting in a rib shape.

  The other portions are knitted using, for example, a normal knitting yarn for the front yarn, and a single-covered yarn covered with a nylon core yarn of 70 to 75 denier on a polyurethane core yarn of 20 to 40 denier as a back yarn.

  FIG. 3 shows another embodiment of the knitting method of the present invention. In this embodiment, the toe pocket 8 at the toe portion is knitted from the instep side portion 83 and the knitting ends at the sole side portion 84 in the embodiment shown in FIG. On the sole side, the opening between the sole side portion 84 and the foot portion 7 is closed by appropriate means such as linking.

  FIG. 4 shows still another embodiment of the knitting method of the present invention. This embodiment is different from the embodiment shown in FIG. 2 in that the connecting portion 3 is not present and the knitting of the heel side 4 is immediately followed by the knitting of the heel side wear mouth portion 2. The other points are the same as those described in FIG.

  The embodiment shown in FIG. 5 is similar to the embodiment of FIG. 2, but is different in that the connecting portion 3 does not exist and the eye is reduced from the time of knitting the heel side mouth portion 2.
