Problems solved by technology

[0032] At this time, as mentioned above, the fixing strength of the front end sprocket 93a relative to the chain belt 92 is absolutely not high, so the front end sprocket 93a is received relatively strongly from the flange because the front end sprocket 93a is caught by the flange of the slider 94. Because of the large load, it is easy to cause the front-end chain element 93a to drop from the chain belt 92 and fall off.

Embodiment Construction

[0091] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, the present invention is not limited to the embodiment described below at all, and various changes can be made as long as it has substantially the same configuration as the present invention and can obtain the same effects as the present invention.

[0092] For example, in the following embodiments, the stopper is arranged on the fastener chain on the right side, and the lateral detachment prevention part is arranged on the left fastener chain to form a slide fastener. However, in the present invention, the fastener chain on the right side may be The fastener chain is provided with a lateral detachment preventing portion, and a stopper is provided on the left fastener chain to form a slide fastener.

[0093] In addition, in the case of the slide fastener of the present invention, the left and right element rows may be composed of a plurali...

Abstract

In this slide fastener (1, 80), a fragile section (15, 86) is provided to an element row (12), and it is possible to detach the element row (12) in an engaged state from the fragile section (15, 86) and to separate first and second fastener stringers (10a, 10b). Lateral withdrawal prevention sections (30, 71, 72, 73, 74, 84) are arranged on the second fastener stringer (10b). The lateral withdrawal prevention sections (30, 71, 72, 73, 74, 84) have a larger thickness, for preventing lateral withdrawal, than the spacing of a tape insertion and passage gap of a slider (50). The lateral withdrawal prevention sections (30, 71, 72, 73, 74, 84) have at least one small-width section (32, 71b, 72b, 72d, 73b, 74b) at a portion provided with a thickness for preventing lateral withdrawal. Even when the slide fastener (1, 80) receives a lateral pulling force, the lateral withdrawal prevention sections (30, 71, 72, 73, 74, 84) are thereby held in the slider (50), and a closed state can be maintained. It is also possible, when the element row (12) is detached from the fragile section (15, 86), to pull out the lateral withdrawal prevention sections (30, 71, 72, 73, 74, 84) from the slider (50) in a smooth manner.

Description

technical field [0001] This invention relates to the slide fastener which arrange|positions the weak part which reduces meshing force locally in an element line, and can release the meshing of the element line on either side from this weak part, and can isolate|separate the fastener element chain on either side. Background technique [0002] For example, International Publication No. 2006 / 103438 pamphlet (Patent Document 1) discloses a slide fastener capable of quickly disengaging the left and right element rows to separate the left and right fastener chains. This type of zipper is sometimes called an emergency opening zipper and has been used in life jackets and the like. [0003] Below, refer to Figure 9 The slide fastener described in Patent Document 1 will be described. In addition, in the following description, the belt length direction of the fastener tape is defined as the front-rear direction, in particular, the direction in which the slider is slid in order to eng...
