JP6401558B2 - Foot cover - Google Patents

Description

  The present invention relates to socks that are worn when wearing shoes such as sneakers, pumps, loafer shoes, etc., that are hidden inside the shoes and cannot be seen from the outside, that is, foot covers. The foot cover may be referred to as cover socks, inner socks, nude socks, or the like.

  Wearing shoes such as sneakers with bare feet as a fashion, or wearing pumps with bare feet without wearing stockings in the summer, but the soles are easy to sweat, and if you leave bare feet inside the shoes It gets steamed.

  For this reason, there is no upper part from the ankle, and the mouth is wide open so that the ankle and at least a part of the instep are exposed. Socks, i.e. foot covers, are used.

  Since such a foot cover has a wide open mouth, there is a problem that the foot cover is displaced during walking or removed from the heel portion. Several proposals have been made to solve such problems.

  For example, in Japanese Patent Laid-Open No. 10-292206 (Patent Document 1), a protruding elastic body made of a rubber material or the like is attached to the inner surface of the heel contact portion of the foot cover, and the protruding elastic body serves as a slip stopper. It is disclosed that it is difficult to remove the foot cover.

  Japanese Patent Laid-Open No. 2013-76205 (Patent Document 2) adheres a belt-shaped flat rubber to the entire circumference of the inner surface of the opening, which is a footwear, and has elasticity and adhesion to the rear inner surface and the front outer surface of the foot cover. It is disclosed to provide a non-slip formed by a silicone gel having a property. In the foot cover of Patent Document 2, a slip stopper on the inner surface of the rear part contacts the wearer's heel to prevent the foot cover from coming off, and a slip stopper on the outer surface of the front part contacts the inner surface of the bottom part of the shoe. Prevents the position of the cover from shifting.

  Japanese Patent Laid-Open No. 2014-47434 (Patent Document 3) discloses that in the foot cover, the first stretchable narrow cloth is downward from the toe side toward the heel side along the upper edge of the toe side of the opening. The second stretchable narrow fabric is tilted upward along the upper edge of the opening from the toe side toward the heel side, and the first stretchable narrow fabric and the second stretch The first and second stretchable narrow fabrics are joined to the foot cover fabric by hot pressing so that the narrow fabric is crossed in the vicinity of the boundary between the sole portion and the side portion. It is disclosed that the narrow fabric and the second stretchable narrow fabric prevent the foot cover from being displaced or detached when worn.

  In the foot covers disclosed in Patent Documents 1 to 3 described above, it is necessary to attach a member other than the foot cover body to the foot cover body in order to prevent the foot cover from being removed when worn. In the foot cover of Patent Document 1, it is necessary to attach a protruding elastic body made of a rubber material or the like to the inner surface of the heel contact portion. In the foot cover of Patent Document 2, it is necessary to attach a belt-like flat rubber to the entire circumference of the inner surface of the opening and to attach a non-slip formed by a silicone gel having stretchability and adhesion to the foot cover body. In the foot cover of Patent Document 3, it is necessary to attach the first stretchable narrow fabric and the second stretchable narrow fabric to the foot cover body.

  Thus, after manufacturing a foot cover main body, attaching a member different from a foot cover main body to a foot cover main body has a problem that it takes time to manufacture the foot cover and the manufacturing cost becomes expensive.

  Further, since a member different from the foot cover main body is attached to the foot cover main body, the appearance is also rugged, and there arises a problem that the separate member peels off during repeated washing.

  The present invention solves the problems of the conventional foot cover, and provides a foot cover that does not take off even when walking while wearing the foot cover, and that does not take time and effort to manufacture, and is inexpensive to manufacture. The purpose is to do.

  The present invention comprises a body part and a mouth part, wherein the body part comprises a toe part, a heel part and an intermediate part, covers the sole, toe and heel when worn, and from the mouth part to the ankle and at least the instep The body part is knitted with a spliced knitting consisting of a front yarn and a back yarn, the front yarn is a yarn made of short fibers or long fibers, and the back yarn is A covered elastic yarn having a urethane elastic yarn (hereinafter referred to as a urethane yarn in the present specification) as a core yarn, and the wear mouth portion is knitted into a bag-like double welt. The bottom weaving part of the double welt is a thick covered elastic yarn that is a single cover with a thin covered yarn using a urethane yarn having a thickness of 200 dtex or more, which is thicker than the urethane core yarn of the back yarn of the body part. Organized The upper part on the inner side of the mouth part and the outer part of the mouth part are the same as the surface yarn in the body part, and the outer part of the mouth part is knitted by rubber yarn insertion knitting. The object is achieved by the foot cover.

  In the present invention, the foot cover is knitted with the thick covered elastic yarn from the lower inner end of the wearing mouth, and is knitted for 3 to 30 courses over the entire circumference of the wearing mouth with the thick covered elastic yarn. It is preferable.

  Further, in the present invention, it is preferable that a portion inside the mouth portion corresponding to the heel portion is additionally knitted partially by the thick covered elastic yarn.

  According to the present invention, the mouth portion of the foot cover is knitted into a bag-like double welt, and the upper part inside the mouth portion and the outer portion of the mouth portion use the same knitting yarn as the surface yarn in the body portion. The outer part of the mouth part is knitted by rubber thread insertion knitting, and the knitting start part of the double welt which is the lower end part inside the mouth part is made from the urethane core thread of the back part of the body part. Since it is knitted with a thick covered elastic yarn that is a single cover with a thin covered yarn with a thick urethane thread of 200 dtex or more as the core yarn, the portion knitted with the thick covered elastic yarn inside the mouth when wearing the foot cover Closely contacts the wearer's foot. In the worn state, the mouth portion is extended from the no-tension state, and the urethane yarn, which is the core yarn of the thick coated elastic yarn, comes into close contact with the skin. Urethane yarn has high frictional force and is difficult to slip, so the foot cover does not come off even if you walk while wearing the foot cover.

  The foot cover of the present invention is manufactured by integrally knitting the body portion and the wearing mouth portion. The knitted part with thick covered elastic yarn inside the mouth part that plays the role of anti-slip is knitted at the start of knitting of the foot cover, and then knitted into the upper part inside the mouth part, the outside of the mouth part, and the body part Is done. Thus, according to the present invention, it can be manufactured only by knitting the foot cover, and there is no need to attach a member different from the foot cover body after the foot cover body is manufactured as in the prior art. Therefore, the foot cover of the present invention does not require time and effort for manufacturing, and the manufacturing cost can be reduced.

  According to the present invention, the foot cover is started to be knitted with the thick covered elastic yarn from the inner lower end of the wearing mouth portion, and is knitted for 3 to 30 courses over the entire circumference of the wearing mouth portion with the thick covering elastic yarn. Further, if the portion inside the mouth portion corresponding to the heel portion is additionally knitted partially by the thick covered elastic yarn, the frictional force of the portion of the foot portion corresponding to the heel portion of the foot cover The foot cover becomes even more difficult to remove.

The state which turned the foot cover of (a) upside down and set the back surface outside is shown. 2A is an enlarged plan view of a portion surrounded by a circle in FIG. 1B, and FIG. 2B is an enlarged cross-sectional view taken along line bb in FIG. 2A. . It is a schematic plan view when another embodiment of the foot cover of the present invention is set on a pattern paper. It is explanatory drawing for demonstrating the knitting process at the time of the knitting start in double welt knitting. It is explanatory drawing explaining progress of the transfer in a double welt organization. It is an expanded view which shows the knitting process of the wear mouth part of one Example of the foot cover of this invention.

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

  As shown in FIG. 1 (a), the foot cover according to the present invention comprises a body part 1 and a mouth part 2, and the body part 1 comprises a toe part 11, a heel part 12 and an intermediate part 13 and is worn when worn. The sole, the toes and the heel of the wearer are covered, and the wearer's ankle and at least a part of the instep are exposed from the wearing mouth 2.

  The foot cover of the embodiment shown in FIG. 1 has a mouth part 2 that is relatively wide open, a toe part 11 that is short, and the ankle and instep of the wearer are exposed. The foot cover shown in FIG. 1 is suitable for being worn when wearing a shoe that exposes the instep.

  Further, when wearing a shoe such as a sneaker that does not expose the instep, the foot opening 2 is not wide open like the foot cover of the embodiment shown in FIG. It is only necessary to wear a foot cover that is long and exposes part of the wearer's ankle and instep.

  In the present invention, knitting is performed using an elastic yarn having a urethane yarn as a core yarn as a knitting yarn so that the body portion 1 of the foot cover fits the wearer's foot. Specifically, the body part 1 is knitted with a splicing knitting composed of a front yarn and a back yarn (splicing yarn), a yarn comprising short fibers or long fibers is used as the front yarn, and a urethane yarn is cored into the back yarn. Use elastic yarns.

  Various materials can be used for the surface yarn depending on the season and application, such as polyester and nylon long fibers, cotton, cotton blend (cotton acrylic, etc.), hemp, hemp blend (cotton hemp, etc.), hair blend ( Acrylic wool blend etc. may be used. The thickness of the surface yarn varies depending on the season and application. For example, in the case of a long fiber yarn, it is as thin as a stocking yarn to about 200 dtex, and in the case of a short fiber yarn, it is 150. About 1000 dtex is often used.

  The backing yarn may be a covered elastic yarn having a urethane yarn as a core yarn. For example, a yarn (FTY) obtained by winding a wooly nylon yarn around a polyurethane yarn, a single covered yarn, a core spun yarn, or the like can be used. The thickness of the urethane yarn that is the core yarn is suitably 20 to 50 dtex, for example, and the thickness of the covering yarn is suitably about the same as or thicker than that of the core yarn.

  The foot cover of the present invention is knitted by a K-type circular knitted sock knitting machine, starts knitting from the wear mouth portion 2, and the body portion 1 is knitted following the knitting of the wear mouth portion 2. The mouth part 2 is knitted into a bag-like double welt.

Description on pages 153 to 154 of “Textile Engineering II Braid” (edited by the Japan Textile Industry Education Research Group, published by Jikkyo Publishing Co., Ltd., 1973), FIG. This will be described with reference to FIG.
[Make up]
* At the beginning of knitting, the cylinder needle should be in every other position. This is done by means of jacks arranged every other line at the bottom of the cylinder.
〇 Every other stitch is made by the first yarn feeding (see Fig. 4 (1)).
〇 All needles work for secondary yarn feeding (see Fig. 4 (2)).
○ The third yarn feeding is made, and every other needle arrangement is made again, and the hook of the dial jack advances over the non-working needles to come into contact with the ribs (see FIG. 4 (3)). As it is, Jack holds the loop, moves back in the dial, and continues that state until the end of the welt knitting.
〇 All needle knitting positions are taken from the fourth yarn supply, and the welt knitting is continued (see FIG. 4 (4)).
This is called make-up. FIG. 4 is a related diagram.
[Transfer]
* When the required length of the welt is knitted (see Fig. 5 (1)), the dial jack advances onto the needle that was in the inactive position while holding the loop of the third yarn feeding on the hook. (See FIG. 5 (2)). The needle rises for knitting and enters the gap at the tip of the jack (see Fig. 5 (3)), and then the jack moves the holding loop to the needle so that when the hook is retracted, the tip breaks into the needle. A loop is left (see FIG. 5 (4)).

  As described above, the bag-shaped double welt is knitted.

  In the foot cover of the present invention, as shown in FIG. 1 (b) and FIGS. 2 (a) and 2 (b), the lower end portion 21 on the inner side (the side in contact with the wearer's foot) of the wearing mouth portion 2 is a double welt. This is the first knitting part (starting part of make-up knitting). A double welt knitting start portion 21 is a single cover of a thin covering yarn at a rough pitch with a urethane yarn having a thickness of 200 dtex or more, preferably 200 to 300 dtex, thicker than the urethane core yarn of the back yarn of the body portion 1 as a core yarn. It is knitted with thick coated elastic yarn. As the thin coated yarn, for example, a long fiber such as nylon of 50 dtex or less, preferably 15 to 35 dtex, which is thinner than the coated yarn of FTY usually used in socks is suitable.

  In the present invention, the thick urethane yarn is not used as a bare yarn (bare yarn), but is covered with a thin covering yarn, so that sliding as a knitting yarn can be secured. Further, since it is necessary that the thick urethane yarn can be knitted by a knitting machine, the upper limit of the thickness is determined by the knitting machine.

  The knitting start portion 21 of the double welt is knitted for 3 to 30 courses, preferably 4 to 20 courses over the entire circumference of the mouth portion by the thick covered elastic yarn.

  Thereafter, the knitting yarn is changed, and the double welt knitting is continuously performed, and the upper portion 22 inside the wearing mouth portion and the outer portion 23 of the wearing mouth portion are knitted. The upper part 22 inside the mouth part and the outer part 23 of the mouth part are knitted using the same knitting yarn as the surface yarn in the body part 1, and preferably a rubber knitting by float knitting (knitting that looks like a so-called rubber knitting style) )). The outer portion 23 of the wear mouth is knitted by a rubber yarn insertion knitting. Preferably, a rubber thread is inserted into the rubber rod. The rubber yarn used for the rubber yarn insertion knitting is not particularly limited, but a covered yarn having a thickness of 70 to 130 is suitable.

  After the knitting of the wear mouth part 2, the body part 1 is continuously knitted. The toe part 11, the heel part 12 and the intermediate part 13 are knitted by splicing knitting using the front yarn and the back yarn. The toe portion 11 and the heel portion 12 can be knitted by changing the swing width of the reciprocating motion of the cylinder of the knitting machine. Subsequent to the mouth portion 2, the toe portion 11 may be knitted first, and conversely, the heel portion 12 may be knitted first. The intermediate part 13 is formed when the toe part or the heel part is knitted. After knitting, the foot cover is completed by bending the open portion between the toe portion 11 and the heel portion 12 by linking or sewing.

  In the present invention, the body portion 1 may be formed by any knitting process as long as it is a spliced knitting using the front yarn and the back yarn described above, and therefore the number, position and shape of the gore line are particularly It is not limited.

Various materials are used for the yarn used in the foot cover of the present invention depending on the season and application, and a specific example is as follows.
* Thick coated elastic yarn at the inner bottom edge of the mouth part: 280 denier (about 311 dtex) polyurethane thread core covered with 20 denier (about 22 dtex) nylon thread (covered thread) * Upper inner part of the mouth part , Outer yarn on the outer part of the mouth and the front yarn of the body part: 150 denier long polyester fiber * back yarn of the body part (attachment): 75 denier polyurethane yarn of 30 denier (about 33 dtex) (about 83 dtex) Yarn covered with polyester yarn (FTY)
* Rubber thread to be inserted into the upper part of the mouth part and the outer part of the mouth part: No. 100 rubber thread of double covered yarn.

  In the double welt knitting of the mouth portion 2 of the embodiment described above, from the first yarn supply until the yarn is replaced, the thick covering elastic yarn is used for the entire circumference of the mouth portion from 3 courses to 30 courses. Be organized. It should be noted that knitting is performed with all the needles until transfer is performed from the fourth yarn feeding and knitting of the wear mouth portion 2 is completed. Therefore, the width of the inside lower end portion 21 of the wearing mouth portion by the thick covered elastic yarn is the same across the entire circumference of the wearing mouth portion 2.

  FIG. 6 is a development view showing a knitting process of another embodiment of the wear mouth portion 2. In FIG. 6, the full width in the horizontal direction represents one turn of the knitting machine, and the vertical direction represents the process of knitting. In FIG. 6, symbol A is the heel side center line, and symbols B and C are boundary lines indicating the range of the heel side.

  In the cuff part 2 of the embodiment shown in FIG. 6, the inner lower end 21 is knitted over the entire circumference of the cuff part by the covered elastic yarn that is 3 to 30 course thick from the primary yarn. The additional portion 21 'is knitted with the swing width between B and C by the reciprocating motion of the cylinder of the knitting machine with the thick covered elastic yarn. Next, the same knitting yarn as the front yarn in the body portion is used, and the upper portion 22 inside the wear mouth portion and the outer portion 23 of the wear mouth portion are knitted by rubber yarn insertion knitting. Thereafter, the loop of the thick covered elastic yarn, which is the third yarn (third course) held in the dial jack, is transferred to the knitting needle, and the knitting of the cuff portion 2 is completed. Subsequently, after knitting several joints 1a of the body part 1 with all the needles, the knitting machine cylinder enters the knitting of the toe part or the heel part by the reciprocating motion of the cylinder (in FIG. 6, the toe part or the heel part). The organization process is omitted).

  In this embodiment, the width of the inner lower end portion of the wearing mouth portion by the thick covered elastic yarn is not the same width over the entire circumference of the wearing mouth portion 2, and the heel side portion is widened by the additional knitting. For this reason, it becomes more difficult to remove the foot cover of this embodiment.
