Problems solved by technology

However, since the coiled linear element 121 covered by the covering method is only one coiled linear element 121, the mounting strength of the tip stopper 110 is weak and unstable.
If a large pulling force is applied to the slider 128 in a state where the slider 128 is in contact with the top end stopper 110, the top end stopper 110 slips off from the coiled linear element 121, so the slider 128 may Running out of coiled, linear sprocket rows, that's a problem to be solved

[0059] Next, a top end stopper of a slide fastener having a coiled or zigzag linear element row according to the first embodiment of the present invention will be described. according to Figure 1-7 The top end stopper of the linear zipper described in the first embodiment shown in , a pair of monofilaments made of synthetic resin such as polyamide or polyester in a coiled or zigzag manner in the zipper longitudinal strip 2 Right and left fastener tapes 3 are formed on opposite side edges 5 . Then, a linear element row 4 constituted by a plurality of linear elements 21 engaged with each other in the longitudinal direction of the fastener tape 3 is formed. The core thread 6 is inserted inside the linear element row 4 , and the core thread 6 and the linear element row 4 are fixed to the side edge of each fastener tape 3 by sewing with a sewing thread 7 . Each linear element 21 consists of a coupling head 22 protruding outward from the side edge of the fastener tape 3, an inver...

[0069] Such as Figure 8 As shown in , according to the second embodiment of the present invention, a characteristic of the top stopper of the zipper having linear element rows is that the top stopper 10 is only on one zipper longitudinal strip 2 of the zipper chain body 1 Formed above, although when the opening device 33 is fixed to the bottom end of the linear chain tooth row 4, the top end stopper 10 is fixed to the top end portion of the linear chain tooth row 4 provided with the box pin 35, while the same top end stop Whether the movable element 10 is fastened to the zip fastener longitudinal strip 2 on the side of the bolt 36 can be freely decided.

[0070] The top end stopper 10 prevents the slider from slipping off the top end of the linear chain element row 4 on the side to which the box pin 35 is fixed. When the slider 28 is pulled hard, the protruding part 11 of the top stopper 10 contacts the front end of the flange 31 in the guide groove 32 of the main body 29, a...

[0072] Figure 9-13 One feature of the shown top end stopper for a slide fastener having linear zipper element rows according to the third embodiment of the present invention is that the element row 4 with the core wire 6 inserted therein is organized by means of a double braided chain. Sewing threads 7 are sewn and secured to the opposite side edges 5 of each zipper tape 3 to complete the zipper slit 2 . A space portion 8 excluding the fastener element row 4 is formed at the end of the zipper longitudinal strip 2, where the top end stopper 10 is formed in a shape that conceals and covers a plurality of linear fastener elements 21 present at the end. . The top end stopper 10 is injection-molded with thermoplastic resin on one surface of the fastener tape 3 on the side with the linear element row 4 . Of course, if image 3 As shown, the top end stopper 10 can be formed into a shape for nipping the fastener tape 3 .

[0073] In order to form the space portion 8 without the l...

Abstract

The object of the present invention is to provide a zipper with a top stopper (10), which enables the top stopper (10) to be securely fixed to the zipper tape (3), preventing the (10) the sewing thread (7) is offset and exposed on the front surface of the top stopper, wherein the linear sprocket row (4) is sewn on the zipper tape (3), and the top stopper (10 ) is formed by covering a plurality of linear elements (21) facing the space portion (8) with synthetic resin, and the protruding portion (11) to be in contact with the slider (28) is formed on the top end stopper (10 ), to prevent the slider (28) from slipping out, a protrusion (37) protruding upward along the sewing line (7) is formed on the front surface of the top end stopper (10), along the protrusion ( 37) is engraved with a concave groove (38) at the center of the longitudinal direction, and by using the protruding ridges provided on the mold for forming the groove (38), the sewing thread (7) moves towards the linear chain tooth (21) Apply pressure to prevent the sewing thread (7) from being deflected and exposed on the front surface of the top stop (10).

Description

technical field [0001] The present invention relates to a slide fastener having a top end stop made of synthetic resin integrally fixed to a space portion formed on a slide fastener chain body by molding. ) so that the top stopper is adjacent to the linear element row in the zipper chain body, which is shaped so that the coiled or zigzag linear element row made of synthetic resin is sewn (sewing) method is secured to the opposite side edges of a pair of zipper ties. Background technique [0002] In the top stopper for a conventional slide fastener disclosed in Taiwan Patent No. 497392, a linear fastener element made of synthetic resin is fixed to a fastener chain body (fastener chain) by sewing. On opposite side edges of a fastener tape, and a top end stopper made of synthetic resin is formed by injection molding at the top end portion of the linear element row. When the coil-shaped linear element row is fixed to the opposite side edges of the fastener tape 103 by sewing a...
