I have. The pair of connecting portions 7 (first connecting portion 9 and second connecting portion 11) are (i) fused with 17 (first fused portion 19 and second fused portion 21) and (ii) lockstitch. It is composed of a seam 23 (first seam 25 and second seam 27).

Specifically, the first connecting portion 9 has (i) one substrate edge 111 of the tape-shaped substrate 101 and the first fabric 201 at the boundary between the slide fastener 3 and the first fabric 201. Reciprocating between the first fused portion 19 to which the cloth edge 203 is fused, (ii) the tape-shaped base material 101, and the first fabric 201 with the first fused portion 19 in between.

Therefore, in the connecting structure 1, it is easy to insert the butterfly rod 119 into the box 115 so as to be adjacent to the box rod 117 from the state where the slide fastener 3 is separated, and the slider portion 105 is slid. It is easy to open and close the element portion 103 and, by extension, the slide fastener 3.

FIG. 5 is an enlarged schematic view of the first connecting portion 9 in the V portion of FIG. Since the second connecting portion 11 has the same structure as the first connecting portion 9, the description thereof will be omitted.
As shown in FIG. 5, a pair of first connecting portions 9 are separated from the first fused portion 19 by a first distance D ₁ and extend in the longitudinal direction LD along the first fused portion 19. It includes a virtual round-trip line, specifically, a first virtual round-trip line L _R1 and a second virtual round-trip line L _R2 . The first virtual reciprocating line L _R1 is arranged on the first cloth 201, and the second virtual reciprocating line L _R2 is arranged on the tape-shaped base material 101.

The first seam 25 linearly reciprocates between the first virtual reciprocating line L _R1 and the second virtual reciprocating line L _R2 while intersecting with the first fusing portion 19 at a predetermined angle θ. Therefore, when a tensile force is applied to the first connecting portion 9 in the orthogonal direction (that is, the width direction WD) orthogonal to the direction in which the first fused portion 19 extends (that is, the longitudinal direction LD), the first seam 25 becomes the first seam 25. Depending on the stretchability of the first cloth 201 and the tape-shaped base material 101 on which the first seam 25 is arranged, the stretchability of the first cloth 201 and the tape-shaped base material 101 on which the first seam 25 is arranged depends on the stretchability. At the same time, the first seam 25 can be deformed so as to be longer in the width direction WD and shorter in the longitudinal direction LD.

In the first seam 25, ignoring the extensibility of the first cloth 201 and the tape-shaped base material 101, the portion of the first seam 25 between the first virtual reciprocating line L _R1 and the second virtual reciprocating line L _R 2 is formed. It can be deformed until it is parallel to the width direction WD. In that case, the first seam 25 has a length between the first virtual reciprocation line L _R1 and the second imaginary reciprocating line L _R2 and (L _S in FIG. 5), the first virtual reciprocation line L _R1 and the second The first seam 25 is deformed so as to be longer in the width direction WD by the difference from the distance between the virtual round-trip lines L _R2 (twice the first distance, twice D ₁ in FIG. 5). Can be done.

Therefore, when a tensile force in the width direction WD is applied to the first connecting portion 9, the first seam 25 can be deformed by a predetermined amount of deformation in accordance with the elongation of the first fabric 201. As the first connecting portion 9 becomes soft, the first fused portion 19 is protected, and the first fused portion 19 is less likely to break.
The same applies to the second connecting portion 11, and when a tensile force in the width direction WD is applied to the second connecting portion 11, the second seam 27 is deformed by a predetermined amount in accordance with the elongation of the second fabric 205. Since it can be deformed by the amount, the second connecting portion 11 becomes soft, the second fused portion 21 is protected, and the second fused portion 21 is less likely to break.

The first connecting portion 9 also includes a pair of inner virtual lines arranged inside the first virtual round-trip line L _R1 and the second virtual round-trip line L _R2 , specifically, the first inner virtual line L _I1 . It has a second inner virtual line L _{I 2} . The first inner virtual line L _I1 and the second inner virtual line L _{I 2} sandwich the first fusion portion 19 in between, and are separated from the first fusion portion 19 by a predetermined second distance D ₂ . The first inner virtual line _LI1 is arranged on the first fabric 201, and the second inner virtual line _LI2 is arranged on the tape-shaped base material 101. The second connecting portion 11 is also the same as the first connecting portion 9.

The first seam 25 is a combination of a plurality of lockstitch stitches at a portion intersecting the first virtual reciprocating line L _R1 , the first inner virtual line L _I1 , the second inner virtual line L _I2, and the second virtual reciprocating line L _R2. It has a part 29. Specifically, at the portion where the first seam 25 intersects the first virtual reciprocating line L _R1 , the first inner virtual line L _I1 , the second inner virtual line L _I2, and the second virtual reciprocating line L _R2 , respectively. It includes a plurality of first crossing portions 31, a plurality of second crossing sections 33, a plurality of third crossing sections 35, and a plurality of fourth crossing sections 37.

For each of the plurality of lockstitching portions 29 (plural first mating portions 31, a plurality of second mating portions 33, a plurality of third mating portions 35, and a plurality of fourth mating portions 37). There is a needle hole (not shown), and in the needle hole, the first thread 39 arranged on the front surface 13 side and the second thread 41 arranged on the back surface 15 side are crossed. The second connecting portion 11 is also the same as the first connecting portion 9.
From the above, in the first connecting portion 9, the first thread 39 and the first thread 39 are compared with the case where the lockstitch crossing portion 29 is present only on the first virtual reciprocating line L _R1 and the second virtual reciprocating line L _R2 . Since the number density of the meshing portions with the second thread 41 increases and the same applies to the second connecting portion 11, the connecting structure 1 is excellent in strength when a tensile force in the width direction WD is applied.

The second distance D ₂ has a size of 50% of the first distance D ₁ . As a result, each of the plurality of second crossing portions 33 is arranged at a position close to each of the plurality of first crossing portions 31, and each of the plurality of third crossing portions 35 is provided with a plurality of fourth crossing portions. Since they are arranged at positions close to each of the portions 37, each of the plurality of first crossing portions 31 to which the largest force is applied when a tensile force in the width direction WD is applied to the connecting structure 1 is subjected to a plurality of positions. Each of the two crossing portions 33 can assist, and each of the plurality of fourth crossing portions 37 can be assisted by each of the plurality of third crossing portions 35.

As a result, each of the plurality of first crossing portions 31 is less likely to break, the needle hole in which each of the plurality of first crossing portions 31 is present is less likely to expand, and the plurality of fourth crossing portions 37 Each of them is less likely to break, and the needle holes in which each of the plurality of fourth crossing portions 37 are present are less likely to expand.
Further, each of the plurality of second crossing portions 33 and each of the plurality of third crossing portions 35 are less likely to break, and a plurality of needle holes in which each of the plurality of second crossing portions 33 exists. It becomes difficult to expand the needle holes in which each of the third crossing portions 35 of the above is present.

Therefore, in the first connecting portion 9, when a tensile force in the width direction WD is applied, a plurality of crossing portions 29 (a plurality of first crossing portions 31, a plurality of second crossing portions 33, and a plurality of first connecting portions 29). The force applied to each of the three crossing portions 35 and the plurality of fourth crossing portions 37) and the force applied to each of the needle holes of the plurality of crossing portions 29 are dispersed, and the same applies to the second connecting portion 11. Therefore, the connecting structure 1 is excellent in strength when a tensile force in the width direction WD is applied.

FIG. 6 is a schematic view for explaining the strength of the connecting structure 1 when a local tensile force is applied to the width direction WD. FIG. 6 is a view of the connection structure 1 on the surface 13 side. As shown in FIG. 6, one hand holds the element portion 103 of the slide fastener 3, and the other hand grips the predetermined grip portion 209 of the first cloth 201 so as to move away from the slide fastener 3. When a predetermined tensile force F is applied to the first cloth 201 in the width direction WD, the first cloth 201 and the slide fastener 3 are deformed in the thickness direction TD, and the plane direction (including the longitudinal direction LD and the width direction WD) is included. In the flat surface), the first cloth 201 extends from the grip portion 209 toward the slide fastener 3 while expanding its range in a substantially fan shape 211, and the slide fastener 3 extends the grip portion 209 of the first cloth 201. A substantially fan-shaped 211 substantially arc 213 is formed around the center. This is because the first cloth 201 has a predetermined extensibility, but the tape-shaped base material 101 has almost no extensibility. Further, with the deformation of the slide fastener 3 into the shape of the substantially arc 213, the first fusion portion 19 constituting the first connecting portion 9 and the first seam 25, which are present on the tape-shaped base material 101. The first seam portion 215 follows the deformation of the slide fastener 3 into the shape of the substantially arc 213.

Of the first seams 25, the second portion 217 of the first seam existing on the first cloth 201 is deformed as the first cloth 201 is stretched. It should be noted that each of the plurality of figures formed by the second portion 217 of the first seam and the first fusion zone 19 has the first crossing portion 31 existing on the first virtual reciprocating line L _R1 as the apex. It is expressed as a virtual isosceles triangle with the first fusion zone 19 as the base.

In the first embodiment, as described above, since the second distance D ₂ has a size of 50% of the first distance D ₁ , the second distance D ₂ is 33.3% of the first distance D _1. Compared with the case (when the crossing portions are evenly arranged), a plurality of first crossing portions 31, which are the portions to which the largest force is applied by applying a predetermined tensile force F, are provided. The second crossing portion 33 can assist. Therefore, the plurality of first crossing portions 31 are less likely to break, and the needle holes in which each of the plurality of first crossing portions 31 are present are less likely to expand. In addition, the plurality of second crossing portions 33 are less likely to break, and the needle holes in which each of the plurality of second crossing portions 33 are present are less likely to expand.

The first fused portion 19 is also deformed into a substantially arc shape as the slide fastener 3 is deformed into a substantially arc 213 shape. Therefore, the first fused portion 19 is subjected to a predetermined tensile force F. Since it is possible to resist the entire portion deformed into the shape of a substantially circular arc and reduce the force applied per unit length of the portion deformed into the shape of a substantially circular arc of the first fused portion 19, the first fusion is performed. The landing portion 19 is less likely to break.
