Embodiment Construction

[0063] With reference to the accompanying drawings, the present invention is taken as an example for further description.

[0064] figure 1 as well as figure 2 A slide fastener is shown, and in detail, it is the waterproof slide fastener 2 of a general type adopted as a reference described in the said patent document 1. As shown in FIG. The slide fastener 2 includes a pair of fastener tapes (hereinafter also simply referred to as "tapes") 4 and 6 having tape layers 5 and 7, which are knitted or woven from polyester or the like, for example. On adjacent edges (adjacent edges of a pair of zipper tapes 4, 6) 20, 22 of the lower surfaces 16, 18 of the tape layers 5, 7 are stitched joining elements 12, 14, as is known in the art. The connecting elements 12, 14 are also called coil-shaped sprockets, which form a single filament into a coil shape to form a continuous coil, and the coil-shaped connecting elements 12, 14 have heads (formed in an enlarged shape) for mutual fitting. ...

Abstract

The invention provides a slide fastener capable of re-interdigitate all of coupling elements some or all of which have been opened, even when the slide fastener has a closed end stop. The slide fastener comprises: a pair of fastener tapes; a pair of coupling elements provided along adjacent edges of the pair of fastener tapes; a slider that engages or separates the pair of coupling elements with or from each other; and an end stop secured to the pair of fastener tapes at an end portion of the pair of coupling elements, wherein the pair of coupling elements are integrally secured to each otherat one region of the end portion of the pair of coupling elements, and wherein the one region extends between a rear end portion of a diamond of the slider and a base portion of the slider in a statewhere the base portion of the slider comes in contact with the end stop.

Description

technical field [0001] The present invention relates to slide fasteners or zip fasteners with end stops. The present invention is particularly effective when applied to a slide fastener having a connecting element, but preferably it can be applied to a slide fastener having a metal connecting element crimped at a predetermined position on the edge of the fastener tape, and it is also preferable to use a forming or forming element. More preferably, the zipper and the end stop of the present invention are used together with a connecting element made of plastic. Background technique [0002] One of the rare disadvantages when using today's slide fasteners or zip fasteners is that, in most zippers, applying sufficient pressure due to folding the zipper, or using sufficient force to press alternate fits Alternate fitting or connection of the connecting elements so that the connecting elements can be disassembled may sometimes cause the tooth chain formed by the alternate fitting...
