Fastener stringer, slide fastener for luggage case, and luggage case

Abstract

Provided are: a fastener stringer which is configured so that fastener elements are prevented from being damaged by a pointed metal object, a thread for sewing the fastener elements to a fastener tape is prevented from wearing away, and the fastener stringer allows a slide fastener to be easily attached to an object to which the slide fastener is to be attached; a slide fastener for a luggage case; and a luggage case. A fastener stringer is provided with a fastener tape (20), a first fastener element row (30A) which is provided to one surface of the fastener tape (20) and which has fastener elements (31), a second fastener element row (30B) which is provided to the other surface of the fastener tape (20) and which has fastener elements (31). The first and second fastener element rows (30A, 30B) are rows of coil-shaped fastener elements. The fastener elements (31) are each provided with an engagement head (31a), an upper leg (31b), a lower leg (31c), and a connection section (31d). The fastener elements (31) of at least one of the first and second fastener element rows (30A, 30B) are each provided with a stepped section (31e) which is provided to the upper leg (31b) so as to be recessed toward the lower leg (31c). A thread (33) for sewing the first and second fastener element rows (30A, 30B) to the fastener tape (20) is disposed in the stepped section (31e).

Description

technical field [0001] The present invention relates to a fastener chain, a slide fastener for bags, and a bag. Background technique [0002] First, in travel bags, a zipper with spiral-shaped zipper teeth is used to open or close the bag. However, if the zipper teeth are touched by sharp metal during the theft, the zipper teeth will be damaged, the engagement between the teeth will be disengaged, and the contents of the bag will be stolen. [0003] And, as the conventional slide fastener that is used for preventing above-mentioned slide fastener element breakage, known slide fastener has such slide fastener (for example, refer to patent document 1): comprise the outside slide fastener that overlaps with each other and inside slide fastener, the slide fastener element of outside slide fastener and inside slide fastener and The fastener tape is arranged so as to be offset in the left-right direction (width direction) of the slide fastener. [0004] Moreover, the slide faste...
