Problems solved by technology

Therefore, when a transverse tension is applied to the slide fastener described in Patent Document 2, and the transverse tension is increased, of course, fracture occurs at the engaging neck portion with a small cross-sectional area, and the slide fastener is in a separated state.

Embodiment Construction

[0054] Hereinafter, typical embodiment of the slide fastener to which the fastener stringer of this invention is applied is demonstrated concretely with reference to drawings.

[0055] figure 1 It is a figure which shows the use example which applied the slide fastener 10 to which the fastener stringers 16 and 17 of this invention were applied to the joining of the fixed net 2 for fish farming. also, figure 2 It is an enlarged plan view of the vicinity of the slide fastener 10 joining the nets 4 of the fixed net 2 .

[0056] exist figure 1 In the illustrated embodiment, the nets 4 constituting the fixed net 2 having a circumference of about 20 m are joined to each other using a plurality of slide fasteners 10 . E.g, figure 1 The shown fixed net 2 is used for tuna farming and has been used continuously for more than 3 years. like figure 1 and figure 2 As shown, since the fixed net 2 is formed by joining a plurality of nets 4 using the slide fastener 10, the manufactu...

Abstract

A fastener stringer is constructed to satisfy the relationship Sn > Sf, where Sn is the minimum cross-sectional area of engaging necks (78) of teeth (13, 12) attached to opposing edges of a pair of left and right fastener stringers (16, 17), and Sf is the cross-sectional area of at least a first base (72U) or a second base (72D). Thus, even when lateral pull exceeding the breaking strength is applied to a slide fastener and some of the teeth break, the engaging heads and the engaging necks of the broken teeth remain engaged with the teeth on the other side and no pieces of the broken teeth remain on the fastener tape.

Description

technical field [0001] The present invention relates to zipper stringers for zippers in which engaging elements break when excessive transverse tension is applied. Background technique [0002] When the zipper is closed and the element rows are engaged with each other, if a pulling force is applied in a direction to separate the pair of left and right fastener stringers, the fastener tape or the engaging elements will be broken when a predetermined lateral pulling force is exceeded. At this time, if the fastener tape breaks, it becomes difficult work to repair the broken fastener tape. [0003] On the other hand, when an excessive lateral pulling force is applied, when a meshing element breaks, the broken meshing element is replaced with a new meshing element, thereby making the work of repairing the slide fastener relatively easy. Especially in a slide fastener using a large engaging element, the slide fastener can be repaired by installing an engaging element for repair i...
