Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sword-back slip-prevention sewing structure for a shirt or the like.

[0002]

[Prior art]

 Conventionally, slits formed on the sleeves for sewing cuffs such as shirts, blouson or blouses cover the bleeds on both side edges of the slits and have overlaps on both side edges. Buttons are attached as opening and closing means, and a cloth piece called a sword boro for forming a buttonhole is sewn on.

As shown in FIGS. 4 and 5 (a), this sword bolster is sewn to one side edge 53a on the right side of the slit in the drawings, and the sword-shaped upper cloth from which its name is derived. It is composed of a piece 51 and a lower cloth piece 52 which is sewn to the other side edge 54a on the left side of the slit in the drawing and which is smaller than the upper cloth piece 51.

When sewing, first, the side edge 58a of the back side portion 58 of the lower cloth piece 52 is sewn 61 to the back side of the slit side edge 54a, and then the lower cloth piece 52 is returned and the back side portion 58 of the back side portion 58 is removed. The front side portion 57 folded in two is overlapped on the upper side, and the side edge 57a where the cut line is folded back and the slit side edge 54a are sewn 62. The same applies to the upper cloth piece 51. After the side edge 56a of the back side portion 56 is sewn 63 to the back side of the slit side edge 53a, the upper cloth piece 51 is returned and pulled out to the front side of the slit. While overlapping on the piece 52, the front side portion 55 folded in two is overlapped on the back side portion 56, and the side edge 55a having the folded crease and the slit side edge 53a are sewn 64. After that, the two folded portions are sewn 65, and the upper and lower cloth pieces 51, 52 are sewn to the sleeve body 50 at the base end of the slit 66, 67 to complete the sewing. A button 59 is sewn 68 to the lower cloth piece 52 in a later step, while a buttonhole (not shown) is formed in the upper cloth piece 51.

The upper and lower cloth pieces 51, 52 of the sword batter thus sewn are mainly intended to cover the cuts of the slit side edges 53a, 54a as described above, and the slit side edges 53a, Since the seam allowance of 54a is sewn to the respective cloth pieces 51 and 52 in a flat state without folding back or the like, when a tensile force F acts on such slit side portions 53 and 54, both side edges 53a of the slit 53a. , 54a and the upper and lower cloth pieces 51, 52 of the sword are sewn together with the thread 61, 62, 63, 64 and the warp threads 53y, 54y of the slit side edges 53a, 54a intersecting with the tension direction. F is directly applied and the tensile force F is received by the frictional force between the warp yarns 53y and 54y and the weft yarn.

Therefore, a material having a weak frictional force that integrates the weft thread and the warp thread of the cloth, that is, a material woven with a thread having a small surface friction coefficient or a cross pattern of the warp thread and the weft thread like plain weave is simple. However, if the material used is a loose thread, a flannel material, or the like, the strength of the seam allowance is insufficient, and if a tensile force F is applied to the slit side portions 53, 54 of the sleeve body 50 when changing clothes, the slit side edge 53a. , 54a, and the warp yarns 53y, 54y for the seam allowance, and the sword batter cloth pieces 51, 52 slipped off.

In particular, in the lower cloth piece 52 of the sword, the width of the seam allowance 54a must be narrowed because the upper cloth piece 51 needs to be covered, and the button 59 is sewn 68. Since the tensile force F is concentratedly applied to the portion where this occurs, in most cases, this portion slips out as shown in FIGS. 4 and 5 (b).

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned points of the conventional sword batter sewing, and an object thereof is to obtain a sewing structure capable of completely preventing the sword batter from slipping off even if the material thread has a poorly driven material thread. It was made as.

[0009]

[Means for Solving the Problems]

 The slits 33 formed on the sleeve tip are sewn to both side edges 31a and 32a of the slit 33, each of which is composed of a front side portion 12 and a back side portion in which one piece of cloth is folded in two along the slit direction. In a sewing structure for a sword batter composed of a pair of cloth pieces 1 and 2 on both sides that cover the cut edges of the side edges 31a and 32a, at least one of the back side portions of the sword batter cloth pieces 12a and 22a and a slit. The side edges 31a and 32a are the front side edge 11a of the sword batter cloth pieces 1 and 2 in which the sword batter cloth pieces 1 and 2 have the seam allowance split after stitching 41, 42 together with the face inner surface of the sleeve, and the folds are folded back. , 21a are overlapped with the seam allowances of the slit side edges 31a, 32a, which are divided by the seam allowance, and are stitched 43, 44 with the slit side edges. Further, the interlining 4 is adhered to the surfaces of the slit side edges 31a and 32a, and the slit side edges 31a and 32a and the partial side edges 12a and 22a of the sword rag cloth are sewn 41 and 42 together with the adhesive interlining 4. I was supposed to.

[Embodiment of the invention]

 Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of a sword batter slip-preventing sewing structure of the present invention. In the figure, the sword bolo is located on the upper side of the upper cloth piece 1 sewn to the right side edge 31a of the slit formed at the tip of the sleeve body 3 and to the left side edge 32a of the slit. It is composed of a lower cloth piece 2 and each of which is formed of a front side portion 11 and a back side portion 12 and 22 formed by folding one piece of cloth into two along the slit direction which is the longitudinal direction thereof. . The sewing process will be described below with reference to FIG.

First, as shown in FIG. 3 (a), an interlining 4 is adhered to a portion where the upper and lower cloth pieces 1 and 2 of the sword are sewn, that is, the surface of the sleeve body 3 in the slit forming portion. Next, as shown in FIG. 3 (b), the upper cloth piece 1 is formed in advance on the back surface of the sleeve body 3 to which the interlining 4 is adhered, and the cut edges of the side edges 11 a and 21 a and the sword tip portion 13 are folded back. , The surface of the lower cloth piece 2 is aligned, and the side edges 12a, 22a of the respective back side portions 12, 22 are sewn in sequence with the slit forming line (33) 41, 42, and then the slits are formed. A slit is formed along the forming line (33) to form the slit 33.

At this time, the slit 33 is further provided with a cut 34 that is branched into a Y-shape at the end of the slit 33 so that the end of each cut 34 reaches the end of the sutures 41 and 42.

Then, as shown in FIG. 3 (c), the lower cloth piece 2 of the sword is pulled out to the front side of the slit 33, and the left side edge 32 a of the slit 42 sewn and the back side portion of the lower cloth piece 2 are separated. The seam allowance of the edge 22a is divided, the front side portion 21 is overlapped on the seam allowance of the slit left side edge 32a, and the side edge 21a and the slit left side portion 32 are stitched 43. The triangular portion 35 between the Y-shaped cuts 34 described above is folded back to the front side.

Further, as shown in FIG. 3D, the upper cloth piece 1 of the sword batter is pulled out to the front side of the slit 33 and overlapped with the lower cloth piece 2, and the slit right side edge 31a and the upper cloth piece 31 which are sewn 41 together. As shown in FIG. 1, the back side portion side edge 12a of the piece 1 is divided into seam allowances, the front side portion 11 is superposed on the seam allowance of the slit right side edge 31a which is divided, and the side edge 11a and the slit right side portion 31 are shown in FIG. The stitches 44 are sewn, and the two folded portions are sewn 45.

Then, in the vicinity of the end of the slit 33, the upper cloth piece 1, the lower cloth piece 2 and the sleeve body 3 are doubly sewn 46, 47 to complete the sewing of the sword batter. In the stitch 47, the triangular portion 35 at the end of the folded slit is also stitched, and in the stitch 46, the portion immediately before the end of the slit 33 is stitched.

As described above, in the upper and lower cloth pieces 1 and 2 of the sewn swords sewn, both slit side edges 31a and 32a of the sleeve body 3 and the back side portions of the cloth pieces 1 and 2 sewn thereto. The seam allowances of the side edges 12a and 22a are each folded back by the seam allowance splitting. Therefore, the weft threads (threads in the left and right direction in FIG. 2) that form the material of the seam allowance portions are also folded back, and the seam allowances are also returned. Each of them intersects with the sewing threads 41 and 42 at the edge point.

Therefore, when a lateral tensile force as shown by F in FIG. 2 acts on both side portions 31 and 32 of the slit 33 sewn with such a sword batter, the tensile force F is slippery. The weft threads of the side edges 31a, 32a and the back side edges 12a, 22a of the cloth pieces 1, 2 will be received by the respective weft threads themselves. The shear strength of the weft threads and the sewing threads 41, 42 is It is much larger than the frictional force that integrates the weft thread and the weft thread.

Further, the upper and lower cloth pieces 1 and 2 of the sword bolster are also sewn 43 and 44 to the slit side portions 31 and 32 separately from the sewn portions 41 and 42 in the front side portions 11a and 21a as well. The tensile force F is shared with the stitched portions 41, 42, and the tensile force acting on each stitched portion is reduced accordingly.

Further, the cloth material itself is reinforced by adhering the interlining 4 to the both side edges 31a, 32a of the slit, and the sewn portions 41, 42 are sewn at the reinforced portions.

Therefore, in the sewn structure according to the present invention, the synergistic effect of these swords significantly improves the tensile strength of the sword bolo consisting of the upper and lower cloth pieces 1 and 2, and the slipping thereof is completely prevented. Despite such strength advantages, the time and effort required for sewing and ironing at the time of sewing, the skills required for sewing, and the appearance are good. In addition, except for the interlining 4, the material for the upper and lower sewn parts is 4 layers (conventionally 5 layers), and the seam allowance is thin, which is advantageous for thick materials and the interlining 4 is attached. However, the seam allowance does not become too thick.

In the above embodiment, the case where the folded-up part of the upper cloth piece 1 is sewn 45 is shown, but it may be omitted depending on the type of shirt. In the case of a material with a low tendency to slip out, the adhesive interlining 4 can be omitted. Even in that case, the tensile strength is significantly improved compared to the conventional blade, and a considerable amount of slip prevention is prevented. The effect is obtained. Further, in the above-described embodiment, the case where the sewing structure of the present invention is used for both the upper and lower cloth pieces 1 and 2 has been shown, but the seam allowance of the slit side edge has to be relatively narrow, and The tensile force is concentrated on the part where the tongue 5 is sewn, and the slipping tendency is more pronounced at that part. Can be obtained.

[Effect of the invention]

 As described above, the sword batter slip-off preventing sewing structure of the shirt of the present invention is sewn to both side edges 31a and 32a of the slit 33 formed at the sleeve tip, and one piece of cloth is sewn along the slit direction. In the sewing structure of the sword bolo consisting of a pair of cloth pieces 1 and 2 on both sides which cover the creases of the side edges 31a and 32a and are composed of the front side portions 12 and 22 and the back side portion which are folded in two, The back side edges 12a, 22a and the slit side edges 31a, 32a of at least one of the sword batter cloths are stitched 41, 42 by joining the inner surfaces of the sleeves together, and then the seam allowance is split, and the bleeds are cut. The front side edges 11a and 21a of the sword batter cloth pieces 1 and 2 which are folded back are overlapped with the seam allowances of the slit side edges 31a and 32a, which are divided by the seam allowance, and the slit side edges and the stitches 43 and 44 are sewn. To be Because, excellent strength level for the tensile force acting in a direction to separate the suture part, even in the sweet materials and flannel material, such as the implantation of the fabric yarns can be prevented from slipping out of the sword rags. Also, since the material for the seam allowance is only four layers, the seam allowance is thin, which is advantageous for thick materials.

Further, in spite of the above advantages, the time and effort required for sewing are not much different from the conventional one, and it is not necessary to sacrifice productivity and cost.

Further, in the above sewing structure, the interlining 4 is adhered to the surfaces of the slit side edges 31a and 32a, and together with the adhesive interlining 4, the slit side edges 31a and 32a and the sword batter cloth back side portion side edge 12a, If 22a and 42a are sewn together, the tensile strength of the sewn portion is further improved, slipping of the sword batter can be completely prevented, and the deformation of the material is prevented during sewing. There is also an advantage that operations such as suturing and seam allowance can be performed easily and surely.
