The Outboard Sections 12 of enhancing part 10 forms with inside part 11 continuous, and is similar with the slide fastener longeron 2 that box pin 8 is housed, and Outboard Sections 12 is formed by rib 13b, the 13c thicker than the rib 13a in the inside part 11.Rib 13b forms like this, be that the width that they are parallel to zipper strip 3 stretches to the outside of zipper strip 3, and between them, have that the front end of this rib 13b is connected by rib 13c along the predetermined space of zipper strip 3 length directions, this rib 13c extends along the length direction of zipper strip 3, thereby forms framework 16.Rib 13c have parallel portion 13c-1 Outboard Sections 12 bottom end sides, that extend along the direction parallel with the length direction of zipper strip 3 and Outboard Sections 12 upper end side, along the sweep 13c-2 of the direction bending of the outer edge part that departs from zipper strip 3.Because the sweep 13c-2 of rib 13c, rib 13b is connected with the obtuse angle with rib 13c-2 corner on framework 16.Like this,, therefore, other object is hooked at the last turning that prevents to strengthen the framework 16 of part 10, separate with zipper strip 3 thereby prevent to strengthen part 10 because the last turning of framework 16 is not sharp-pointed.Each rib 13b and 13c form and make cross sectional shape is isosceles triangle, and the angle of inclination of side is about 60 °, like this, prevents from contact with sewing needle when sewing slide fastener longeron 2, thereby protects rib 13 to be without prejudice.
Be formed at enhancing part 10 on the slide fastener longeron 2 that box pin 8 is housed and inserts pin 9, that constitute by inside part 11 and Outboard Sections 12 by on the injection-molded front surface and rear surface that is formed at zipper strip 3, therefore, clamp by strengthening part 10 front surface of zipper strip 3 and rear surface.Strengthen part 10 and can only be formed on the single surface of zipper strip 3, rather than both side surface.
In the box 7 on being installed on the slide fastener longeron 2 that box pin 8 is housed (this box is a rectangular solid), shown in Fig. 8 and 9, narrow dividing plate 29 is arranged between antetheca 25 and the rear wall 26 and on the top at center, and mate 32 is arranged on the bottom of dividing plate 29.Patchhole 28 is arranged on the sidewall 27 of box 7 sides, this patchhole 28 is the openings of thickness that equal to strengthen the inside part 11 of part 10, and the slide fastener longeron 2 that box pin 8 is housed can pass this patchhole 28 and insert, simultaneously, box pin insertion hole 30 is arranged between this patchhole 28 and the dividing plate 29, and box pin 8 can pass this box pin insertion hole 30 and insert.Patchhole 28 is arranged on another sidewall 27 and up to the bottom, this patchhole 28 is the openings of thickness that equal to strengthen the inside part 11 of part 10, and the slide fastener longeron 2 that inserts pin 9 is housed passes this patchhole 28 insertions, simultaneously, the patchhole 31 that inserts pin is arranged between this patchhole 28 and the dividing plate 29, insert patchhole 31 insertions that pin 9 can pass this insertion pin, form box 7 like this.
As shown in figure 10, the box pin 8 that the slide fastener longeron 2 of box pin 8 is housed is inserted in the box pin insertion hole 30 in the box 7 of formation, and the inside part 11 that strengthens part 10 is inserted in the patchhole in the sidewall 27, and is arranged in dividing plate 29 in the box 7 and is pressed in the recess 17 in the side that is arranged in box pin 8.Therefore, be arranged in the end engagement of mate 32 and recess 17 on the bottom of dividing plate 29, thereby box pin 8 and box 7 be bonded to each other and fixing.
When the slide fastener longeron 2 that insertion pin 9 is housed is installed on the slide fastener longeron 2 that box 7 is housed, by slider 35 being slid into contact and keeping contacting with this box with the top of box 7, as shown in figure 11, will insertion pin 9 be inserted in the guiding grooves 37 by pinching the enhancing part 10 that the slide fastener longeron 2 that inserts pin 9 is housed.And the inside part 11 that strengthens part 10 inserts between the flange 36, inserts in the pin 9 insertion pin insertion holes 31 that are inserted in the box 7 thereby make.Then, when by pinching when strengthening part 10 and spur slider 35 and this slider 35 is slided, formation slide fastener chain 1, wherein, the slide fastener elements 4 on left and right slide fastener longeron 2 is engaged with each other, as shown in figure 12.
Separable bottom retainer 5 shown in Figure 13,14 and 15 has been represented the version of the Outboard Sections 12 in strengthening part 10.In the enhancing part 10 shown in Figure 13, the fitting limit of inside part 11 and Outboard Sections 12 is with respect to box pin 8 and insert the long and broad of pin 9.Therefore, the quantity of the rib 13b that extends along horizontal direction in the framework 16 in Outboard Sections 12 increases, and the scope that the outward flange of zipper strip 3 strengthens is become wideer.
In the enhancing part 10 shown in Figure 14, although inside part 11 is installed in box pin 8 and inserts the fitting limit that the fitting limit of selling on 9 equals first embodiment, the structure difference of the rib 13b in Outboard Sections 12.Just, in Outboard Sections 12, not along the rib 13b of lateral arrangement, still single rib 13c is arranged vertically in framework 16, and therefore, rib 13c can depart from the sewing circuit of sewing machine, thereby reduces the impaired frequency of rib 13c.Therefore, slide fastener longeron 2 can firmly be sewed effectively.And because therefore the rib 13c that the enhancing part shown in Figure 15 10 does not have on the outboard end of Outboard Sections 12 does not form framework 16, the outside that strengthens part 10 can have flexibility.
For enhancing part 10 shown in Figure 16, that be used to insert pin 9, be integrally formed in the bottom of the enhancing part 10 of inserting pin 9 sidepieces and be positioned at the inside, bottom of inserting pin 9, like this, the bottom of it and zipper strip 3 is spaced apart, just, compare with the bottom of inserting pin 9, below the bottom that strengthens part 10, have the surplus part of zipper strip 3.Because this structure, when outside twisting resistance was applied on the zipper strip 3, it was not directly passed to rib 13a, 13b, but the surplus part of the zipper strip 3 that at first leads.Therefore, rib 13a, 13b are not easy to separate with zipper strip 3.
And, adopt the thermal cutting method to come from the independent slide fastener longeron 2 of continuous along its length slide fastener longeron cutting predetermined length.Because the bottom part of slide fastener longeron 2 is by adding thermal cutting, therefore, the yarn of forming zipper strip 3 is bonded to each other in the position that forms bonding portion 19.Because the cutting tip at zipper strip 3 forms bonding portion 19, therefore, can prevent this cutting tip wearing and tearing.And thermal cutting is being carried out near the line of cut that is parallel to the width of zipper strip 3 as the edge, position of selling 9 bottoms with reference to the insertion of point, and therefore, the core 6 of zipper strip 3 extends to a shade below the bottom of inserting pin 9, thereby obtains good quality.In addition, this also can be used for being equipped with the slide fastener longeron 2 of box pin 8.
