Slide fastener

Abstract

The invention provides a slide fastener that has a left and right pair of fastener stringers having element rows arranged thereon, an insert pin and a box pin each formed integrally with one end of a corresponding one of the element rows, and a first slider (10) having a first pull tab (12) and a second slider (20) having a second pull tab (22), the first and second sliders (10, 20) being passed over the element rows with respective rear openings of the first and second sliders opposed to each other. The first and second pull tabs (12, 22) have engaging structures for engaging the first and second pull tabs with each other. When the first and second pull tabs (12, 22) are engaged with each other, the first and second sliders (10, 20) are retained in a state in which the rear openings are opposed to each other. The first pull tab (12) is pivotably connected to a first slider body (11) via a first link section. Engaging the pull tabs of the first and second sliders (10, 20) with each other reliably positions the first and second sliders (10, 20) relative to each other to allow smooth insertion of the pin into the sliders. Thus, the construction improves the easiness of operation of the slide fastener.

Description

technical field [0001] The present invention relates to a reverse-openable zipper in which the first and second sliders are inserted through the element row of the zipper stringer with their back openings facing each other, and more particularly relates to the ability to smoothly insert the insertion tube into the first and second sliders. Among the two sliders, the zipper can easily slide the first and second sliders simultaneously. Background technique [0002] Conventionally, in order to open and close the left and right front sides of clothes, a slide fastener having opening and separating inserts at the lower end of the element row or a slide fastener that can be opened in reverse is often used. [0003] Such a reversible slide fastener for clothing is generally configured such that the element rows can be opened from both ends. For example, in this type of slide fastener, a fastener element row is arranged on each element mounting part of a pair of left and right fast...

Problems solved by technology

Therefore, there is the following problem: after the first and second sliders 131, 132 are moved to the socket-side end of the element row 122, if the tongue piece 132a of the second slider 132 is not checked every time the first slider 131 When the notch 131a is fitted, the insertion tube 123 cannot be smoothly inserted into the first and second sliders 131, 132.

In such a case, there is also a problem that the insertion tube 123 cannot be fully inserted into the first and second sliders 131, 132, and the left and right element rows 122 cannot be stably engaged.
