The present invention relates to a slide fastener in which a coiled fastener element is fixed by a large indentation of the tape edge.

A slide fastener fixed by a tape large indentation in which a coil-like fastener element is an element support is generally formed by the upper and lower parts of the element part and the thread (weft) and the weft thread disposed on the outer circumferential axis of the element connection inversion. Since the element is fixed only by the metabolism (inclined) and the weft thread disposed on the outer side of the lower side and the element connecting inverting part, the element is easily moved in the longitudinal direction in the large indentation, and there is a problem in that there is no attachment safety. Also, when the chain is bent or pushed up from the bottom, the inclination of the large inlet part slips and shifts toward the connection inversion part of the element, thereby weakening the force to press the element, and the chain is cracked or the element tends to be doubled.

The present invention has been made in view of the above-described points, and tightens the element corners with the fastening thread to the large vertical weft threads to prevent the elements from shifting in the longitudinal direction and the inclination of the elements, thus eliminating the defects described above. The purpose is to provide a slide fastener.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(E) is a coiled fastener element, in which a core string 5 is disposed so as to touch the inside of the connection inverting portion 1, and two strands 4a and 4b so as to touch the outside of the connection inversion portion 1. ) Is arranged.

The string yarn 5 is used for twisted yarn. As the pads 4a and 4b, a string with a seam wrapped around the outer periphery of the screening layer made of bundles or steamed yarns is used.

The coiled fastener elements E, the seam string 95, and the pads 4a and 4b are integrally woven in the large indentation 7 of the tape 6. This large incidence part 7 is comprised as follows. That is, the coating inclination 9... Continuous to the local inclination 8. . The weft yarns 10 arranged in the tape paper structure for these inclined groups. The element E core string 3 and the cover strings 4a and 4b are integrally elongated. As is clear from the figure, the weft yarns 10 are arranged in two double picks with respect to one pitch of the element, and at the same time, the respective inclined warp groups 9... Goes down once for every four pick cycles with respect to weft 10.

In addition, the slide fastener described in this embodiment feeds the tape into a needle loom and simultaneously feeds the synthetic resin monofilament to the straight edge of the tape as if it is coiled together with the tape. Weft can be arranged in two double picks, for example.

A pair of tightening chambers 11 and 12 are arranged in the large inlet portion 7. One of the tightening chambers 11 passes downward from the upper part of the upper part 2a of the element E to the outside of the weft part 10a of the upper part 2a side, and then to the weft thread 10b of the lower part 2b side. It is placed so that it repeats every pitch of elements. The other tightening chamber 12 passes from the outside of the lower weft part 2b side weft thread 10b to the upper side of the lower weft part 2b outside, and is caught by the upper weft part 10a of the upper leg part 2a side. It is arranged to repeat every time. In this manner, the upper and lower angle portions 2a and 2b of the element E are firmly fastened to the weft thread 10 by a pair of tightening cores 11 and 12.

In addition, in the embodiments of FIGS. 1 to 3, the inclined chambers 11 and 12 are inserted between the inclined yarns 9 and are in contact with the core string 5 so that the inclined yarns are disposed on the occlusal head side of the element. Does not slide to the side of the connection inversion.

4 to 6 show another embodiment of the present invention, and in addition to the core string 5, the auxiliary core string 13 is made, and the pair of tightening chambers between the core string 5 and the auxiliary core string 13 ( 11) 12 is arranged. In this embodiment, the weft yarn 10 is caught by the auxiliary braid 13, and the weft yarn 10 is tightened by the tightening chamber 11 and 12 between the core braid 5 and the auxiliary braid 13 Therefore, a strong tensile force is applied to the weft yarn 10, and the adhesion strength of the element becomes higher.

In each of the above embodiments, the tightening chambers 11 and 12 tighten the elements every one pitch, but may be inserted to span two or more pitches. In addition, if synthetic fibers having a greater heat shrinkage than the inclined yarns 9 and the weft yarn 10 of the large vertical indentation are used in the tightening chambers 11 and 12, when the tape is heat treated such as dyeing, it is firmly tightened by the heat shrinking of the tightening chamber. There is strength.

As described above, according to the present invention, the upper and lower parts of the element are tightened by a pair of tightening chambers, and thus the elements do not move in the longitudinal direction from the large vertical part, and the tightening thread is also tightened because the fastening chamber is walked between the upper and lower parts and the weft yarns. A slide fastener with high attachment stability of the element is obtained. In addition, the inclined yarn disposed on the element occlusal head side rather than the tightening chamber is blocked because of the tightening chamber and is not pushed toward the connecting inverting part. Since the flow of the upper and lower angle portions, that is, the inclination of the occlusal head decreases, the sliding to the connection inversion portion is similarly prevented.

In this way, since the inclined slope does not slip, the chain is broken or pushed up from the bottom so that the chain does not split or the element is doubled.
