Description

  The invention according to the claims relates to a stretch boot having a beautiful silhouette that fits a leg when worn, and a method of manufacturing the same.

  In recent years, stretch boots have been attracting attention because of the stretchability of the fabric and the effect of making the legs look clean by fitting the legs when worn. The conventional stretch boots 21, 22, and 23 shown in FIG. 3 are formed by cutting a flat fabric with a nail mold along the legs and then sewing them to cover the upper part of the foot and the upper leg part. And a cylindrical portion covering the.

A similar boot using stretchable fabric is described in, for example, Patent Documents 1 and 2 below. The thing of patent document 1 is comprised by putting a sock on the shoe main body (portion which covers the ankle or less) etc., and the thing of patent document 2 uses an elastic material on the upper part, and an outer surface. A breathable tarpaulin is sewn on the arch.
Utility Model Registration No. 3099211 Utility Model Registration No. 3063508

  The conventional stretch boots 21, 22, and 23 shown in FIG. 3 are sewn after the fabric is cut, so the seams (seams) 21 a, 22 a, 23a. If there is a seam in a portion visible from the outside, it is generally disadvantageous in appearance. In addition, in order to cut the fabric, it is necessary to create a cutting die for each design and each size, and the waste of the fabric is generated, resulting in waste of manufacturing labor and costs. .

  The boot described in Patent Document 1 has a small number of seams because the sock can be put on the shoe body without sewing, but the decorative leather 6 is sewn on the toe portion, so that it is a prominent part of the instep. There will be seams. Also, since the socks themselves often include seams in the vicinity of the heels and toes, the boots cannot particularly eliminate the disadvantages in appearance due to the seams.

  When the boots described in Patent Document 2 are worn, the upper stretchable material is in close contact with the legs to prevent the air from flowing out, and when removed, the upper part is bent to confine the air, so that there is odor in the boots. In order to solve the problem of accumulation, a breathable waterproof sheet is provided on the arch. However, even in the boot, at least a sewn portion for the breathable waterproof sheet is formed between the outer side surface and the arch portion, and the appearance is impaired. Also, if there is no highly breathable part at the top, the boot is limited to use only in the fall or winter, since it looks hot even if there is a vent part on the arch.

  In order to solve the above-mentioned problems, the claimed invention is more preferable in appearance and can be manufactured at low cost, and further, the odor does not easily accumulate inside, and it looks cool and can be worn in spring etc. An object is to provide a manufacturing method.

In the stretch boot according to claim 1, first, a tubular fabric including a lace-like mesh is formed without sewing on a portion above the ankle, and the integral fabric with the tubular fabric is an ankle. It is continuous from the upper part to the part below the ankle without going through the sewing part, and the entire stretch stop piece that defines the shape of the part covering the back of the foot to the rear part of the heel is covered only with the fabric And FIG. 1 shows an example of a stretch boot according to the present invention, in which the cylindrical portion 3 is a portion above the ankle and the upper portion 4 corresponds to a portion below the ankle.

The stretch boot of the present invention has the following operational characteristics. Ie
i) Since the part above the ankle and the part below the ankle (including the part covering the instep etc.) are made of a continuous fabric that does not go through the sewing part, the silhouette is simple and clean appear. In addition, it is easy to manufacture because there are few parts. Compared with the boots described in Patent Document 1 described above, the exterior is not sewn in the portion covering the instep, and the entire stretch stop piece is covered with only one fabric. This is particularly advantageous.

  ii) Since the tubular fabric above the ankle contains a lace-like mesh and the part is breathable, when worn, or when the upper part is bent after taking off In addition, it can eliminate internal stuffiness and prevent odors from accumulating. The skin looks transparent and looks cool, so it can be used as a fashion suitable for spring. Since internal steaming can be eliminated, there is no need to sew a ventilation sheet or the like on the arch or the like as in the example of Patent Document 2.

In the stretch boot according to claim 1 , the fabric is attached to the stretch stop piece at a portion covering the stretch stop piece, and the fabric is a portion below the ankle and only at the rear portion of the heel. to also characterized by having a seam stitched with elongation locking piece (seam. sewing portion).

This stretch boot has the following advantages.
iii) There is a seam only at the position of the rear part of the heel among the parts below the ankle, but the seam at that position is inconspicuous, and there are no seams at other positions, i.e. the instep and its sides, so silhouette Is still simple and beautiful.

iv) Since a seam is provided at the position of the rear part of the heel, it is possible to attach an extension stop piece to a portion below the ankle in a planar state until the seam is stitched. Therefore, it is easy to perform the pasting work of the stretch stop piece.
In addition, when the stretch boot is configured so as not to have a seam at any position including the rear part of the heel, since the part below the ankle is also cylindrical from the beginning, a part of that part (that is, from the instep of the foot) Appropriate skill is required for the work of attaching the stretch stop piece to the rear part of the bag.

The manufacturing method of the stretch boots described in claim 2
1) A fabric comprising a cylindrical part extending above the ankle and a flat part because the part that becomes the rear part of the heel below the ankle is discontinuous between the left and right, is formed without sewing,
2) Attach an extension piece that defines the shape of the flat part covering the back of the foot to the back of the heel, and then discontinuate the discontinuous part that is the back of the heel from the outside of the extension piece. Stitch together with the fabric,
3) Invert the front and back of the entire fabric including the cylindrical part and the stitched part.
4) A shoe sole is attached to the opening edge of the end on the side below the ankle. The procedure shown in FIGS. 2A to 2F is an example according to the manufacturing method of this claim.

The manufacturing method of this claim has the following advantages. That is,
i) The part above the ankle made of a non-sewn tubular fabric and the part below the ankle from the instep to the back of the heel where the stretch stop piece is pasted Therefore, for example, a stretch boot having a beautiful silhouette described in claim 1 can be manufactured smoothly. The seam can be made only at the rear part of the heel, but the seam of the part is not conspicuous and there is no seam other than the rear part of the heel, such as the back of the foot or both sides, so the beauty of the silhouette is not impaired.

  ii) Although a seam can be formed only at the rear part of the heel, before the seam is sewn, the stretch stop piece is attached to the flat portion of the fabric formed in the above 1), so that the attaching operation in the above 2) is easy to perform. The stitching operation after pasting can be easily performed because the stitches are formed on a flat portion. In addition, since the entire fabric including the stitched part is reversed in 3), the seam (seam) becomes inconspicuous.

According to a third aspect of the present invention, there is provided a method for manufacturing a stretch boot, wherein the fabric having a cylindrical portion and a planar portion (the fabric of 1 of claim 2 ) is laced into the cylindrical portion. It is characterized in that it is formed without sewing by knitting from a thread so as to include the mesh.

According to the manufacturing method of this claim, there are the following advantages.
iii) Knit stretch boots can be manufactured by knitting from yarn. During production, yarns are knitted to form a cylindrical fabric, so there is no need to create multiple types of punches for different designs and sizes, and no fabric chips are generated. The lace-like mesh can be easily formed in any shape without using a punching die or the like.
The above fabric (from 1) above is knitted from yarn and formed without sewing, either by a) hand knitting or b) three-dimensional non-sewing knitting called WHOLEGARMENT (registered trademark), etc. It can be carried out by using a flat knitting machine having a function, or c) by the method of claim 4 .

The manufacturing method according to claim 4 is the V bed flat knitting having the needle bed before and after the above-mentioned fabric (the fabric of 1 of claim 2 ) having a cylindrical portion and a planar portion. The machine is knitted and formed by reciprocating the carriage and rotating the knitting yarn around the knitting needle on the front needle bed and the knitting needle on the rear needle bed and feeding them alternately. To do.

  According to such a manufacturing method, the above-described fabric including a cylindrical portion can be obtained smoothly and efficiently without sewing. In order to give the necessary shape to the cylindrical portion of the fabric, the knitting width may be increased / decreased by changing the number of knitting needles held at the operating position during knitting (Japanese Patent Laid-Open No. 60-194154). No. publication).

Since the stretch boot according to claim 1 is formed of a continuous fabric in which a portion above the ankle and a portion below the ankle are integrally formed, the silhouette looks simple and beautiful. There is also an advantage that it is easy to manufacture because the number of parts is small. In addition, since the part above the ankle includes a lace-like mesh and has air permeability, the inside is not stuffy and odor is difficult to accumulate, and it looks cool and is suitable for spring.
Since the stretch boot of claim 1 is provided with a seam in part, it is easy to perform the work of attaching the stretch stop piece. However, since the seam is inconspicuous, the silhouette is still simple and beautiful.

The stretch boot manufacturing method according to claim 2 can smoothly manufacture the stretch boot having the advantages as described above. The work of sticking stretch-stretching pieces to the fabric and stitching them together can be done easily.
According to the method for manufacturing stretch boots according to claim 3 , it is possible to manufacture stretch boots of knitted fabric by knitting from yarns, the fabric is not wasted (yield is good), and the stitches are patterned. it can.
If it is the manufacturing method of Claim 4 , the cylindrical fabric used as a manufacturing raw material can be obtained smoothly and efficiently without sewing.

  An embodiment of the invention will be described with reference to FIGS. FIG. 1 is a perspective view of the stretch boot 1, and FIGS. 2A to 2 F are explanatory diagrams relating to a method for manufacturing the stretch boot 1.

  As shown in FIG. 1, the stretch boot 1 is formed of a stretchable integral continuous fabric 2 having a cylindrical portion 3 above the ankle and an instep portion 4 covering from the instep to the back of the heel. In addition, a shoe sole 15 and a heel 16 are attached below the upper portion 4. The fabric 2 is provided so as to cover the entire outer surface of the boot 1 (except for the sole 15) by itself. The fabric 2 is knitted from yarns, and the tubular portion 3 is provided with a lace-like mesh 3a so that the skin color of the foot can be seen from the mesh 3a without overlapping the fabric. An extension stop piece 10 for determining the shape of the shoe is joined to the inside of the upper part 4 of the fabric 2. The fabric 2 is provided with a seam 5 (a seam, a sewn part) at the rear part of the upper part 4 of the upper part 4, but no seam is provided at other parts. Therefore, this stretch boot 1 has a feature that the appearance is simple and beautiful, and the inside has a lace-like mesh 3a and air permeability, so that the inside is hard to be stuffy and looks cool. The shape and dimensions of the boot 1, the material and thickness of the fabric 2 (including pantyhose-like ones), the mode of the mesh 3 a (including patterns and roughness of the eyes), and the like are not limited to the illustrated examples. Needless to say.

  Such a stretch boot 1 can be manufactured according to the following procedures 1) to 5) along FIG.

Procedure 1): First, a fabric 2 having a cylindrical portion 3 on the side that becomes the upper end 2a and the upper portion 4 on the side that becomes the lower end 2b is, for example, sewn by a V-bed flat knitting machine (not shown). Knit so that there is no (Fig. 2 (a)). The tubular portion 3 is formed with a lace-like mesh 3a. The upper part 4 is the part below the ankle, but by providing a cut 4a at the rear part of the heel and making the left and right sides discontinuous, it is flat rather than cylindrical (one piece folded at the toe part) Knitting).
The V-bed flat knitting machine has a needle bed on the front and rear, reciprocates the carriage, and alternately turns the knitting yarn around the knitting needle on the front needle bed and the knitting needle on the rear needle bed. It is an apparatus for knitting a cylindrical knit by supplying yarn. The number of knitting needles maintained at the operating position is changed by a program so that the upper part 4 and the cylindrical part 3 fit the leg, and the knitting is performed while increasing or decreasing the knitting width. It is also possible to provide a mesh 3a. For example, a flat knitting machine having a three-dimensional non-sewing knitting function referred to as WHOLEGARMENT (registered trademark) may be used. Of course, the tubular fabric can be formed by hand-knitting.
If it carries out as mentioned above, cloth 2 will be formed three-dimensionally without sewing, and since it is not necessary to cut cloth, it will not produce a chip.

  Procedure 2): A stretch stopper piece 10 is prepared as a member that covers the instep of the foot to the back of the heel and defines its shape (FIG. 2 (b)). The stretch stop piece 10 is formed, for example, by cutting a slightly thick and rigid synthetic fiber sheet. The stretch stop piece 10 is provided with a halved end 10a and a slit 10b at a place where the ankle enters.

Procedure 3): The stretch stop piece 10 prepared in 2) above is overlapped and pasted on the upper part 4 of the fabric 2 knitted in 1) above (FIG. 2 (c)). The pasting may be performed by hot pressing, but an adhesive may be used.
The upper part 4 can be knitted into a cylindrical shape without providing the cut line 4a, and the stretch stop piece 10 can also be formed into a single curved surface (cylindrical shape) without being divided into left and right sides, and can be bonded by hot pressing or the like. It is. However, the upper part 4 is divided into left and right sides by the cut 4a and knitted into a flat shape, and the extension piece 10 is also flat, so that the work of the above heat press is facilitated and different designs and There is no need to prepare several types of press tables for each size, which can reduce manufacturing costs and labor.

  Procedure 4): The halved end portion 10a of the stretch stop piece 10 is sewn together with the fabric 2 near the cut 4a of the upper portion 4 as a seam 5 (FIG. 2 (d)). Thereby, the upper part 4 also becomes a cylindrical shape which continues from the upper part.

  Step 5): The tubular fabric 2 including the stitched upper portion 4 is reversed so that the front and back are reversed (FIG. 2 (e)). Since the upper cylindrical portion 3 is only a single layer, there is no change in the lace-like mesh 3a or the like. However, in the upper portion 4 corresponding to the lower portion, the stretch-stopping piece 10 is located inside the fabric 2. The seam 5 becomes inconspicuous as it is hidden. Since there is no seam other than the rear part of the heel, the outer surface of the fabric 2 after the inversion has a very smooth and beautiful silhouette.

  Procedure 6): The shoe sole 15 and the heel 16 are attached to the opening edge 2c of the fabric 2 on the side of the upper part 4 (FIG. 2 (f)).

1 is a perspective view of a stretch boot 1 as an embodiment of the invention. 2A to 2F are explanatory views showing a method for manufacturing the stretch boot 1 as an embodiment of the invention. 3A to 3C are perspective views showing conventional stretch boots 21, 22, and 23, respectively.
