Embodiment one:
as shown in FIG. 1, a flat bottom resin zipper comprising two zipper strips 100 and a zipper head 200, and as shown in FIG. 2, each of the zipper strips 100 is composed of a zipper cloth 10, a zipper rack 20 and a plurality of stitches 30, for constituting a flat bottom zipper structure of a zipper having only the zipper cloth 10 and no protruding zipper teeth, provides a zipper further manufactured to be anti-pinch or invisible. Wherein:
as shown in fig. 2, the sprocket 20 comprises a flexible core wire 21, the core wire 21 is made of a plurality of nylon filaments or natural fibers, and a plurality of resin sprockets 22 are injection molded on the core wire 21. As shown in fig. 3 to 6, each of the resin sprockets 22 is integrally injection-molded with a rectangular block 221 made of plastic or synthetic resin, through holes 222 communicating both sides of the rectangular block 221, a sprocket head 223 formed at one end of the rectangular block 221 for engagement, and a thread insertion groove 224 recessed from the upper surface to the lower surface of the rectangular block 221, the thread insertion groove 224 being a semicircular groove, both ends of which extend to both sides of the rectangular block 221. When the resin sprocket 22 is injection molded, a core wire 21 is first passed through the mold, and then each of the resin sprockets 22 is injection molded on the core wire 21, so that the core wire 21 is fixed to the through hole 222, and the resin sprockets 22 are arranged at intervals on the core wire 21.
As shown in fig. 3 and 4, the first resin sprocket 22 of the present embodiment has a supporting block 225 integrally formed at one end of the rectangular block 221 of the resin sprocket 22, and the supporting block 225 is a triangular block with a tip facing the sprocket head 223, so that the supporting block 225 is integrally connected to the lower surface of the sprocket head 223. The two sides of the sprocket head 223 are respectively formed with an engagement protrusion 2231 and an engagement recess 2232, such that the engagement protrusions 2231 of the two sides of the sprocket head 223 protrude from the two sides of the supporting block 225, and the width between the engagement recesses 2232 is smaller than the width of the supporting block 225, thereby forming a supporting surface 2251 on the bottom end of the engagement recess 2232 of the supporting block 225. This allows the engagement protrusion 2231 to abut against the support surface 2251 of another sprocket to engage with the engagement recess 2232 when the resin sprocket 22 is engaged.
The above-mentioned chain teeth 20 of the present utility model can be injection molded in advance by the core wire 21 in series structure, not directly molded on the chain cloth 10, so that the chain teeth 20 can be manufactured first, and then the corresponding chain teeth 20 can be selected according to the color or size of the chain cloth 10 to be sewn on the chain cloth 10. As shown in fig. 2 and 6 to 8, the zipper teeth 20 are disposed on the second surface of the zipper 10 in parallel during the stitching process, so that the lower surface of the rectangular block 221 is attached to the second surface of the zipper 10, and the zipper teeth 223 protrude from the inner side of the zipper 10. Then, a plurality of stitches 30 are used for stitching, the stitches 30 are wound in the stitch caulking grooves 224 of the resin sprockets 22, the stitches 30 are stitched between the resin sprockets 22, and the resin sprockets 22 are stitched and fixed on the second surface of the chain cloth 10.
After the above construction is sewn, as shown in fig. 2 and 6, the inner side of the chain cloth 10 is folded back toward the outer side of the chain cloth 10 together with the chain rack 20, so that the chain cloth 10 forms a toothed belt 11 and a sliding space 12 between the toothed belt 11 and the chain cloth 10. Therefore, the sprocket 20 is positioned on the sprocket 11 opposite to the sliding space 12, and the two first stitches 31 are positioned on the first face of the sprocket 11. With this structure of the reverse-folding slider 10, a flat bottom slider structure is formed in which only the slider 10 is provided on one surface of the slider and the protruding tooth surface is not provided, and the tooth-free surface can be used as the back surface (inner surface) of the anti-pinch slider, so that the teeth and slider are positioned on the front surface (outer surface) of the slider, and the resin teeth 22 are prevented from being pinched to the inner lining of the clothing. The non-toothed side can also be used as the front (outer) side of the concealed slide fastener, with the teeth and slider hidden on the back (inner) side of the slide fastener, so that the outer side of the garment is free of protruding resin teeth 22 and sliders, and the difference between the anti-pinch slide fastener and the concealed slide fastener is only that the conventional slider structure is different.
To stitch the zipper strip 20 to the zipper cloth 10, the conventional nylon zipper seam structure is not feasible, and for this purpose, as shown in fig. 2, 6 to 8, a plurality of seams 30 according to the preferred embodiment of the present utility model are implemented with two first seams 31 and one second seam 32. The two first stitches 31 are located on the first side of the chain cloth 10, the two first stitches 31 are continuously threaded to the second side of the chain cloth 10 at the gaps between the resin sprockets 22 by a sewing machine, and then reversely folded to be threaded back to the first side of the chain cloth 10, so that the two first stitches 31 form two loops 311 at each gap of the second side of the chain cloth 10, and the two first stitches 31 are fastened to the first side of the chain cloth 10. The second thread 32 is formed by repeatedly passing two loops 311 of the first thread 31 on both sides of each resin sprocket 22 on the second surface of the sprocket 10, and the second thread 32 is continuously operated by a sewing machine to form three thread bodies 321 where each second thread 32 is fastened in the thread caulking groove 224. Thereby, the three-stage wire body 321 not only tightens the resin zipper teeth 22, but also embeds the three-stage wire body 321 in the seam caulking groove 224, so that the sliding and falling off of the resin zipper teeth 22 can be prevented, and the friction of the zipper head 200 to the second seam 32 can be avoided.
As shown in fig. 9, 10 and 11, the second resin sprocket 22 in this embodiment is also integrally injection molded with a rectangular block 221, the rectangular block 221 is also provided with a through hole 222 for fixing the core wire 21, and a suture caulking groove 224 is also provided on the rectangular block 221, which is different from the first embodiment in that: the height of the head 223 of the resin zipper 22 is the same as that of the rectangular block 221, so that the triangular supporting block 225 is not provided under the head 223, so that the head 223 at one end of the entire resin zipper 22 can be engaged with each other for the two fastener tapes 100, and the structure and method for sewing the same to the zipper cloth 10 (shown in fig. 11) are the same as those of fig. 6 to 8, so that the description thereof will not be repeated. As can be seen from the resin zipper 22 shown in fig. 9 to 11, the present utility model can implement different zipper heads 223 to achieve the purpose of flat bottom resin zipper, so that different tooth forms of other zipper heads can be adopted.
As shown in fig. 4, 6 and 10 and 11, the rectangular block 221 of the resin sprocket 22 of the present utility model may have at least one fastener inserting groove 227 recessed from the bottom to the top, and the fastener inserting groove 227 is preferably a groove having a rectangular or semicircular cross section and is connected to both sides of the rectangular block 221, and by the structural design of the fastener inserting groove 227, when the first thread 31 is fastened to the first surface of the fastener fabric 10, not only the first thread 31 is sunk into the soft fastener fabric 10, but also the fastener fabric 10 is pressed by the first thread 31 and then inserted into the fastener inserting groove 227 (as shown in fig. 6 or 11), thereby forming a combined structure in which the fastener fabric 10 and the fastener inserting groove 227 are engaged, so that the fastener of the present utility model can effectively resist the transverse tension of the fastener fabric 10.

Then, as shown in fig. 14, a plurality of stitches 30 'are sewn into the stitch caulking groove 224' and the chain cloth caulking groove 227 'of each of the resin sprocket 22', and the stitches 30 'are sewn into the chain cloth 10' at the gap between each of the resin sprocket 22', so that the stitches 30' are inserted and tightened into the stitch caulking groove 224 'and the chain cloth caulking groove 227', and the chain cloth caulking groove 227 'can serve as a positioning groove for the engagement of two first stitches 31 in addition to the above-mentioned embodiment, thereby achieving the effect of reinforcing the bonding stability of the resin sprocket 22' and the chain cloth 10', and preventing the stitches 30' from moving or being worn.
As shown in fig. 14 and 15, after the resin element 22 'is injection-molded on the fastener tape 10', the inner side edge of the fastener tape 10 'is reversely folded toward the outer side edge of the fastener tape 10' to form a fastener tape 11 'and a sliding space 12' between the fastener tape 11 'and the fastener tape 10', so that the element head 223 'of the resin element 22' protrudes from the reversely folded edge of the fastener tape 10', thereby forming a flat bottom slide fastener having only the fastener tape 10' and no protruding resin element 22 on one surface thereof. The slide fastener according to this embodiment can also be manufactured by using the face without the fastener element (only the fastener tape 10 ') as the back face (inner face) of the anti-pinch slide fastener and the face with the resin fastener element 22' as the front face (outer face) of the slide fastener, so that the resin fastener element 22' does not contact the inner liner of the clothing, and the resin fastener element 22 is prevented from being pinched to the inner liner of the clothing. The zipper manufactured in this embodiment has a face without teeth as the front face (outer face) of the concealed zipper, and a face with resin teeth 22 'as the back face (inner face) of the zipper, so that the resin teeth 22' are hidden behind the zipper, and the outer face of the garment has no protruding resin teeth 22.
In this embodiment, referring to fig. 14 and 15, the suture 30' also includes two first sutures 31' and a second suture 32'. The two first stitches 31 'are wound around the cloth caulking groove 227' provided in the resin sprocket 22', the second stitches 32' are prevented from moving or being worn, and the two first stitches 31 'are continuously threaded to the second face of the sprocket band 11' at the space between the respective resin sprockets 22', and are reversely folded and then threaded back to the first face of the sprocket band 11' (refer to fig. 2), so that two loops 311 'are formed at the space of the second face of the sprocket band 11'. The second thread 32' is repeatedly passed through the two loops 311' of the first thread 31' on both sides of each resin sprocket 22' on each resin sprocket 22', so that each second thread 32' forms a multi-segment thread body 321' embedded and fastened in the thread embedded groove 224', thereby achieving the effects of fastening the resin sprocket 22' and preventing the first thread 31' and the second thread 32' from moving or being worn, and the zipper can effectively resist the transverse pulling force of the zipper cloth 10.
