The front-rear direction is the length direction of the fastener tape 10 and is also simply called the tape length direction. The left-right direction is the width direction of the fastener tape 10 and is also simply referred to as the tape width direction. Regarding the description of the present specification, it is also possible to read the front-rear direction in the tape length direction and the left-right direction in the tape width direction to understand the technical contents.

Each fastener stringer 40 has a fastener 300 provided adjacent to the fastener element 20 at the tape side edge 13. Although not necessarily limited to this, the stopper 300 illustrated in FIGS. 1 to 3 is a front stop 300. The stopper 300 is provided to prevent the slider 50 from moving forward. In some cases, the stop 300 is used as a back stop. The stopper 300 is a resin lump fixed to the core string 14 of the fastener tape 10 by resin injection molding. Unlike the fastener of Patent Document 1, the fastener 300 of this embodiment is configured and designed so as not to allow the slider 50 to be detached from the fastener stringer 40.

2 and 3, when the slider 50 takes the most advanced position, the left and right stoppers 300 are accommodated in the slider 50, and only a part of the stopper 300 is disposed outside the slider 50. As shown in FIG. 1, the left-side stop 300 may be indicated as a stop 300M, and the right-side stop 300 may be indicated as a stop 300N.

As shown in FIGS. 4 to 10, each stopper 300 has a base portion 310 fixed to the core string 14 of the tape side edge portion 13 and a protruding portion 320 that protrudes outward from the base portion 310 to the fastener tape. The base portion 310 includes an upper base portion 311 and a lower base portion 312 that sandwich the core string 14 of the tape side edge portion 13. The protrusion 320 connects the upper base 311 and the lower base 312 outside the fastener tape of the base 310.

The outward direction of the fastener tape refers to a direction from a point or position on the tape upper surface 11 or the tape lower surface 12 of the fastener tape toward a point or position outside the tape upper surface 11 or the tape lower surface 12. Typically, the outer side of the fastener tape crosses the core string 14 of the fastener tape 10 as it goes from a point or position on the tape upper surface 11 or the tape lower surface 12 to a point or position outside the tape upper surface 11 or the tape lower surface 12. The inner side of the fastener tape is in the direction opposite to the outer side of the fastener tape. The inside of the fastener tape is a direction from a point or position outside the tape upper surface 11 or the tape lower surface 12 of the fastener tape to a point or position on the tape upper surface 11 or the tape lower surface 12.

As shown in FIG. 4, each fastener 300 includes a first end 351 adjacent to the fastener element 20, a second end 352 opposite to the first end 351, and the first end 351 and the second end 351. It has an intermediate part 353 in the middle of the end part 352. The first end 351 of the stopper 300 is an inserted portion that is inserted into the slider 50. The intermediate part 353 is an inserted part that is at least partially inserted into the slider 50. On the other hand, the second end 352 includes a portion that is not inserted into the slider 50. An opening 370 reaching the core string 14 is provided between the first end 351 and the second end 352 of the stopper 300. The opening 370 passes through the upper base 311 or the lower base 312. A holding pin is used to hold the core string 14 when the fastener 300 is injection-molded with respect to the core string 14 of the fastener tape 10. The opening 370 is formed from the pressing pin. The opening 370 in the illustrated example has a rectangular shape when viewed from the front, and more specifically has a rhombus shape.

In one embodiment, the fastener 300 is injection molded to the fastener tape 10 together with the fastener element 20. In another form, the fastener 300 is injection molded to the fastener tape 10 after or before the fastener element 20 is injection molded.

As shown in FIGS. 6 and 7, and FIGS. 9 and 10, each stopper 300 includes an upper ridge 330 and a lower ridge protruding in opposite directions on the upper surface 301 and the lower surface 302 of the stopper 300. Part 340. The upper raised portion 330 and the lower raised portion 340 are provided not near the first end portion 351 but near the second end portion 352, respectively. In the illustrated example, the upper raised portion 330 and the lower raised portion 340 are provided at the second end portion 352, respectively. The upper raised portion 330 and the lower raised portion 340 exist in the same plane in the plane PL2 orthogonal to the core string 14. Upper ridge 330 and lower ridge 340 protrude in opposite directions on plane PL2. In short, the upper raised portion 330 protrudes upward away from the lower raised portion 340. The lower raised portion 340 protrudes downward away from the upper raised portion 330.

The fastener element 20 has an upper base portion 21 and a lower base portion 22 that sandwich the core string 14 of the tape side edge portion 13, and a head portion 24 connected to the upper base portion 21 and the lower base portion 22 via a neck portion 23. The front-rear width of the neck 23 is narrower than the front-rear width of the head 24. The heads of the left and right fastener elements 20 are arranged between the left and right adjacent fastener elements 20, whereby the engagement of the left and right fastener elements 20 is achieved. In some cases, protrusions are provided on the front and rear sides of the neck portion 23 and are fitted in corresponding recesses of the head 24 of the mating counterpart.

Although not necessarily limited to this, in the case of the illustrated example, the fastener element 20 is thinned, and high flexibility is imparted to the fastener stringer 40. For example, the left-right width of the fastener element 20 is L3 as shown in FIG. 5, and the thickness of the fastener element 20 is TH3 as shown in FIG. In some cases, TH3 / L3 <0.6 is satisfied. In some cases, TH3 / L3 <0.55 is satisfied. The lateral width of the fastener element 20 is the length of the fastener element 20 along the width direction of the fastener tape 10. Therefore, the left and right width of the fastener element 20 may be called the length of the fastener element.

In some cases, (TH3m + TH3n) /TH3≧0.4 is satisfied. In some cases, (TH3m + TH3n) /TH3≧0.45 is satisfied. As shown in FIG. 7, TH3m indicates the thickness between the upper surface of the upper base portion 21 of the fastener element 20 and the upper vertex of the core cord 14. As shown in FIG. 7, TH 3 n indicates the thickness between the lower surface of the lower base portion 22 of the fastener element 20 and the lower apex of the core cord 14. Regarding the structure of the fastener element 20, the entire contents of WO2015 / 046497 are incorporated herein by reference.

The stopper 300 according to the illustrated example has a thickness TH1 equal to the thickness TH3 of the fastener element 20, as shown in FIGS. In short, the first end portion 351 and the intermediate portion 353 of the stopper 300 have a thickness TH1. Stopper 300 also has a thickness TH2 that is greater than thickness TH1. The thickness of the upper raised portion 330 is added to the thickness of the upper base portion 311 and the thickness of the lower raised portion 340 is added to the thickness of the lower raised portion 340. As a result, the fastener 300 has a thickness TH1. Greater thickness TH2.

In some embodiments, 1.4 <TH2 / TH1 <1.85 is satisfied. In some embodiments, 1.4 <TH2 / TH1 <1.8 is satisfied. In some embodiments, 1.5 <TH2 / TH1 <1.85 is satisfied. In some embodiments, 1.6 <TH2 / TH1 <1.7 is satisfied. In some embodiments, the thickness TH3 of the fastener element 20 is 2.2 mm or less, and the thickness TH1 of the first end 351 of the fastener 300 is also 2.2 mm or less. The maximum thickness TH2 of the second end 352 of the stopper 300 is 3.7 mm or less. In a specific embodiment, TH1 = 1.9 mm, TH2 = 3.1 mm, TH3 = 1.9 mm.

The fastener 300 according to the illustrated example can contribute to the expansion of the design of the fastener 300 while maintaining the original function of the fastener 300. The essential function of the stop 300 is to stop the slider 50 more reliably.

In the present embodiment, the upper raised portion 330 extends across the core string 14 across the base portion 310 and the protruding portion 320, as illustrated directly in FIGS. More specifically, the upper raised portion 330 extends across the upper base portion 311 and the protruding portion 320 so as to cross the core string 14. Similarly, as shown in FIGS. 6 and 9, the lower raised portion 340 extends in a manner across the core string 14 across the base portion 310 and the protruding portion 320. More specifically, the lower raised portion 340 extends in a manner across the core string 14 across the lower base 312 and the protrusion 320. The fixing force of the fastener 300 to the core string 14 of the fastener tape 10 is enhanced by the upper bulge portion 330 and the lower bulge portion 340, and the upper bulge portion 330 and the lower bulge portion 340 extending in the left-right direction provide more reliable restraint of the slider 50. Is achieved.

In some cases, the slider 50 is restrained at a total of two places on the right and left ones 300. In another case, as shown in the drawing, the slider 50 is restrained at a total of four positions of the left and right stoppers 300. In the latter case, the upper wing plate 51 of the slider 50 comes into contact with the upper raised portions 330 of the left and right stoppers 300, and the lower wing plate 52 of the slider 50 comes into contact with the lower raised portions 340 of the left and right fasteners 300. In any case, the fixing force of the fastener 300 to the core string 14 of the fastener tape 10 is enhanced by the upper bulge portion 330 and the lower bulge portion 340, and the upper bulge portion 330 and the lower bulge portion 340 extending in the left-right direction are sliders. 50 more reliable restraints are achieved.

When the slider 50 is made of resin, there is a concern that the distance between the upper wing plate 51 and the lower wing plate 52 of the slider 50 increases, and the slider 50 gets over the stopper 300 and falls off the slide fastener 60. However, the stopper 300 in the illustrated example is not limited to contact with the flange portion 56 of the slider 50, and contacts the slider 50 at a plurality of locations closer to the connecting column 53 than the flange portion 56. Therefore, it is possible to avoid or suppress the slider 50 from getting over the stopper 300. Note that such a problem does not occur when the slider 50 is made of metal. The slider referred to in the present application can be made of metal, resin, or other materials.

The upper raised portion 330 and the lower raised portion 340 are provided in an area limited in the fastener 300, in the second end portion 352 in the illustrated example. Therefore, the provision of the upper raised portion 330 and the lower raised portion 340 avoids a significant increase in the weight of the fastener 300 and a significant increase in the material cost of the fastener 300.

In the illustrated example, the upper raised portion 330 has a height H330 that gradually decreases as the distance from the core string 14 increases along the tape width direction. Similarly, the lower raised portion 340 has a height H340 that gradually decreases as the distance from the core string 14 increases along the tape width direction. When the upper bulging portion 330 and the lower bulging portion 340 extend from the second end 352 to the left and right at a certain height, the upper bulging portion 330 and the lower bulging portion 340 become enormous, and the restraining force of the stopper 300 increases. It may be. However, in this case, the thickness of the protruding portion 320 of the stopper 300 increases by the thickness of the upper raised portion 330 and the lower raised portion 340. When the slider 50 is advanced, there is a concern that the human hand may come into contact with the protrusion 320 having an increased thickness. In the illustrated example, the restraining force of the fastener 300 can be increased without sacrificing the operability of the slider 50.

As shown in FIGS. 6A and 9A, planes PL4 and PL6 parallel to each other perpendicular to the tape width direction are set. The plane PL4 is in contact with the outer peripheral part of the innermost portion of the core string 14 and is orthogonal to the fastener tape 10. The plane PL6 is in contact with the outer peripheral portion of the core string 14 that is the outermost of the fastener tape. The gradual decrease in the height of the upper ridge 330 starts between the plane PL4 and the plane PL6. Similarly for the lower raised portion 340, the gradual decrease in the height of the lower raised portion 340 starts between the plane PL4 and the plane PL6. A balance between securing a sufficient fixing of the stopper 300 to the core string 14 and avoiding or suppressing an increase in the thickness of the protrusion 320 is ensured.

The upper raised portion 330 has a downward inclined surface 331 that inclines downward as it extends outward from the top surface 335 of the fastener tape. In the illustrated case, the top surface 335 of the upper raised portion 330 is a flat surface substantially parallel to the upper surface 301 of the fastener 300 provided with the upper raised portion 330. The starting point of the downward inclined surface 331 is between the plane PL4 and the plane PL6. The lower raised portion 340 is provided with a downwardly inclined surface 341 that inclines downwardly as it extends outward from the top surface 345 of the fastener tape. The top surface 345 of the lower raised portion 340 is a flat surface substantially parallel to the lower surface 302 of the fastener 300 provided with the lower raised portion 340. The starting point of the downward inclined surface 341 is between the plane PL4 and the plane PL6. In the illustrated example, the inclination of the downward inclined surface 331 and the inclination of the downward inclined surface 341 are substantially equal, and a uniform appearance of the fastener 300 can be ensured. In some cases, the

top surfaces

335, 345 can be non-planar surfaces, eg, curved surfaces.

In another example, the upper raised portion 330 has a height that gradually increases as the distance from the core string 14 increases along the tape width direction. Similarly, the lower raised portion 340 has a height that gradually increases as the distance from the core string 14 increases along the tape width direction.

Note that the second end portion 352 of the stopper 300 is the above-described upper raised portion 330 and lower raised portion 340, so that the fastener tape outwardly as shown in FIGS. 6 (b) and 9 (b). It includes a tapered shape that tapers as it extends.

The upper raised portion 330 has an upper inclined surface 332 that is inclined downward from the top surface 335 toward the first end 351 side of the stopper 300 along the tape length direction. Similarly to the upper raised portion 330, the upper inclined surface 332 also extends across the upper base portion 311 and the protruding portion 320 so as to cross the core string 14. The lower raised portion 340 has a lower inclined surface 342 inclined downward from the top surface 345 toward the first end 351 side of the stopper 300 along the tape length direction. The lower inclined surface 342 also extends in a manner that crosses the core string 14 across the lower base 312 and the protrusion 320, similarly to the lower raised portion 340. Both the upper inclined surface 332 and the lower inclined surface 342 are stop surfaces that stop the movement of the slider 50. The upper inclined surface 332 contacts the front end portion of the upper wing plate 51 of the slider 50, and contacts the front end portion of the upper wing plate 51 in the illustrated example. The lower inclined surface 342 contacts the front end portion of the lower wing plate 52 of the slider 50, and in surface contact with the front end portion of the lower wing plate 52 in the illustrated example.

As shown in FIGS. 5 and 8, the stopper 300 includes an outer periphery of the upper surface 301 and an outer periphery of the lower surface 302 in addition to the upper surface 301 provided with the upper raised portion 330 and the lower surface 302 provided with the lower raised portion 340. It has an outer peripheral side surface 303 to be connected. The outer peripheral side surface 303 extends between the facing surface 304 facing the fastener element 20, the facing surface 305 on the opposite side of the facing surface 304, and the facing surface 304 and the facing surface 305 to connect the facing surface 304 and the facing surface 305. The first and second connection surfaces 306 and 307 are provided.

The first connection surface 306 can contact the flange portion 56 of the slider 50 as shown in FIG. The first connection surface 306 includes a first connection surface of the upper base portion 311 and a first connection surface of the lower base portion 312 that are partitioned by the fastener tape 10. The second connection surface 307 is provided on the outer side of the fastener tape than the first connection surface 306. The second connection surface 307 has two convex portions 350 projecting outward from the fastener tape. As shown in FIG. 3, when the stopper 300 is accommodated in the slider 50, the convex portion 350 provided near the first end 351 of the stopper 300 can contact the connecting column 53 of the slider 50. . The facing surface 304 includes a facing surface of the upper base 311, a facing surface of the lower base 312, and a facing surface of the protrusion 320. The opposite surface 305 includes the opposite surface of the upper base 311, the opposite surface of the lower base 312, the opposite surface of the protrusion 320, the opposite surface 333 of the upper ridge 330, and the opposite surface 343 of the lower ridge 340. In some cases, the facing surface or the opposite surface is simply referred to as a side surface.

The upper raised portion 330 has an opposite surface 333 on the opposite side of the upper inclined surface 332 in the tape length direction. The opposite surface 333 of the upper raised portion 330 is a side surface continuous with the opposite surface of the upper base portion 311. The lower raised portion 340 has an opposite surface 343 that is opposite to the lower inclined surface 342 in the tape length direction. The opposite surface 343 of the lower raised portion 340 is a side surface continuous with the opposite surface of the lower base portion 312.

The upper raised portion 330 has an upper inclined surface 332 and an opposite surface 333 continuous with the opposite surface of the upper base 311 on the opposite side, and does not appear to rise sharply. The lower raised portion 340 has a lower inclined surface 342 and an opposite surface 343 continuous with the opposite surface of the lower base 312 on the opposite side, and does not appear to rise sharply.

As shown in FIGS. 5 and 8, the facing surface 304 of the fastener 300 is provided adjacent to the head 24 of the fastener element 20, and the fastener element 20 extends in accordance with the outward extension of the fastener tape from the core string 14. It includes a tape outer region 304m that is gradually separated from the head 24. In some cases, the tape outer region 304m facilitates the stop 300 to assume the correct posture when traveling into the slider 50. The tape outer area 304m also contributes to making the fastener 300 appear smaller.

As shown in FIGS. 5 and 8, a first inclined region 361 that is inclined downward toward the fastener element 20 is provided between the upper surface 301 and the opposing surface 304 of the stopper 300. Between the upper surface 301 of the stopper 300 and the second connection surface 307, a second inclined region 362 that is inclined downward as it extends outward from the fastener tape is provided. The first inclined area 361 and the second inclined area 362 are provided in a manner that bends between the tape outer area 304 m and the upper surface 301. These first and second

inclined regions

361 and 362 help the fastener 300 to assume the correct posture when traveling into the slider 50. The first and second

inclined regions

361 and 362 also contribute to making the stopper 300 appear thin.

7B and 10B, a third inclined region 363 that is inclined downward toward the fastener element 20 is provided between the lower surface 302 and the facing surface 304 of the fastener 300. As shown in FIG. Between the lower surface 302 of the stopper 300 and the second connection surface 307, a fourth inclined region 364 that is inclined downward as it extends outward from the fastener tape is provided. The third inclined region 363 and the fourth inclined region 364 are provided so as to bend between the tape outer region 304 m and the upper surface 301. These third and fourth

inclined regions

363, 364 facilitate the stop 300 to take the correct posture when traveling into the slider 50.

As described above, the fastener element 20 in the illustrated example is thinned, and the fastener 300 is similarly thinned. The fastener stringer 40 having such a thinned fastener element 20 and fastener 300 can have high flexibility. On the other hand, the fastener stringer 40 is twisted due to the high flexibility of the fastener stringer 40, and the stopper 300 collides with the upper blade plate 51 or the lower blade plate 52 of the slider 50, and the stopper 300 is inserted into the slider 50. That can be prevented.

When the stopper 300 collides with the upper wing plate 51 or the lower wing plate 52 of the slider 50, a force that causes the detachment from the core string 14 can act on the stopper 300. When the stopper 300 is partially thinned like the fastener element 20, the fixing force of the stopper 300 to the core string 14 can also be reduced. In the present embodiment, the stopper 300 includes the first to fourth inclined regions 361 to 364 described above, and the smooth insertion of the stopper 300 into the slider 50 is promoted. Therefore, it is possible to avoid or suppress the stopper 300 from being detached from the core string 14 while promoting partial thinning of the stopper 300. The first to fourth inclined regions 361 to 364 contribute to exerting the restraining force of the stopper 300 including the upper raised portion 330 and the lower raised portion 340 described above. However, the first to fourth inclined regions 361 to 364 are also useful in a fastener that does not include the upper raised portion 330 and the lower raised portion 340.

Referring to FIGS. 11 to 24, it will be described that the stopper 300 takes a correct posture when proceeding into the slider 50. In FIG. 11 to FIG. 24, the illustration of the fastener tape is omitted for convenience of illustration.

As shown in FIG. 16, the upper blade 51 of the slider 50 is provided with an upper inclined end face 51k with which the upper raised portion 330 of the stopper 300 can come into contact. The upper inclined surface 332 of the upper raised portion 330 of the stopper 300 can come into surface contact with the upper inclined end surface 51k. The upper inclined end surface 51k is an inclined surface that extends upward as it extends forward. The lower wing plate 52 of the slider 50 is provided with a lower inclined end surface 52k with which the lower raised portion 340 of the stopper 300 can contact. The lower inclined surface 342 of the lower raised portion 340 of the stopper 300 can come into surface contact with the lower inclined end surface 52k. The lower inclined end surface 52k is an inclined surface that extends downward as it extends forward. The upper inclined end surface 51k and the lower inclined end surface 52k are arranged to face each other in the vertical direction. The vertical interval between the upper inclined end face 51k and the lower inclined end face 52k increases toward the front. These inclined end faces facilitate the stop 300 to take the correct posture when traveling into the slider 50.

As shown in FIG. 17, the upper inclined end surface 51 k is inclined so as to be directed upward in accordance with the separation from the connecting column 53 in the left-right direction. The lower inclined end face 52k is inclined so as to be directed downward as it is separated from the connecting column 53 in the left-right direction. Accordingly, it is further promoted that the stopper 300 takes a correct posture when proceeding into the slider 50. The upper wing plate 51 of the slider 50 has an opposed inner surface 51 m that faces the lower wing plate 52. The lower wing plate 52 has an opposed inner surface 52 m facing the upper wing plate 51. The opposing

inner surfaces

51m and 52m are flat surfaces parallel to each other. An upper inclined end surface 51k is disposed in front of the opposed inner surface 51m. A lower inclined end surface 52k is disposed in front of the opposed inner surface 52m.

When the slider 50 moves forward as shown in FIGS. 11A to 11C, the stopper 300N first enters the slider 50, and then the stopper 300M enters the slider 50. When the posture of the stopper 300N is corrected as shown in FIGS. 12A and 12B, the first inclined region 361 and / or the stopper 300N as shown in FIG. 13, FIG. 16, and FIG. This is because the second inclined region 362 contacts the upper inclined end surface 51k of the upper blade 51 of the slider 50, and the stopper 300N rotates as indicated by the arrow in FIG.

When the posture of the stopper 300M is corrected as shown in FIGS. 12B and 12C, the first inclined region 361 and / or the stopper 300M as shown in FIGS. This is because the second inclined region 362 contacts the upper inclined end surface 51k of the upper blade 51 of the slider 50, and the stopper 300M rotates as indicated by the arrow in FIG.

As shown in FIGS. 21 to 23, after the rotation of each of the above-described stoppers 300, each of the stoppers 300 can take an appropriate posture within the slider 50. As shown in FIG. 24, the advancement of the slider 50 is blocked by the upper raised portion 330 and the lower raised portion 340 of each stopper 300. At this time, the upper inclined surface 332 of the upper raised portion 330 is in surface contact with the upper inclined end surface 51 k of the upper blade 51. The lower inclined surface 342 of the lower raised portion 340 comes into surface contact with the lower inclined end surface 52k of the lower blade 52. The left and right fasteners 300 restrain the slider 50 at a total of four locations. A stable stop of the slider 50 is achieved.

As shown in FIG. 24, when the stopper 300 stops the slider 50, that is, the upper wing plate 51 of the slider 50 is in surface contact with the upper raised portion 330 of the stopper 300, and the lower wing plate 52 of the slider 50 is the stopper 300. An upper step 91 is formed between the upper surface of the upper wing plate 51 and the top surface 335 of the upper ridge portion 330 when the lower ridge portion 340 is in surface contact with the lower ridge portion 340. A lower step 92 is formed between the surfaces 345. The slider 50 can be more reliably restrained without significantly reducing the thickness of the stopper 300. The thickness TH2 of the second end 352 of the stopper 300 is less than the vertical width W50 between the upper surface of the upper wing plate 51 of the slider 50 and the lower surface of the lower wing plate 52.

In FIG. 12 and the like, the case where each stopper 300 is in contact with the upper inclined end face 51k of the upper blade 51 is shown. The case where each stopper 300 contacts the lower inclined end surface 52k of the lower blade 52 is similarly understood.

Based on the above teaching, those skilled in the art can make various modifications to the embodiments. Reference signs included in the claims are for reference only and should not be referenced for the purpose of limiting the scope of the claims.
