Embodiment Construction

[0086] Hereinafter, typical embodiment of the slide fastener with an insertion-separation tool which concerns on this invention is demonstrated concretely, referring drawings.

[0087] figure 1 It is a figure which looked at the quick-open slide fastener 10 from the surface side, and this quick-open slide fastener 10 is a slide fastener which can separate the closed fastener stringer on either side rapidly, independently of the slide of the slider 50. In addition, by figure 1 The shown seat tube 40 , cannula 30 , socket 40B constitute a plug-in-separation part.

[0088] figure 1 The shown quick-open slide fastener 10 is an opening and closing tool that can open and close left and right front body parts, for example, in jackets, emergency clothes that require instant release, and the like.

[0089] The quick-opening slide fastener 10 has: the left and right first zipper stringers 16 and the second zipper stringers 17 constituting the zipper; The left and right cores 14 arra...

Abstract

Disclosed is a slide fastener with a separable bottom end stop comprising a box (40B) having a box insert portion (40Z) into which a butterfly pin (30) is inserted. The four sides of the box insert portion (40Z) are configured from a front wall (40C), a rear stopper protrusion (40E), a box pin-side wall (40H) and a separable-side stopper protrusion (40D) and, accordingly, a wide opening is able to be formed in the sides thereof where the rear stopper protrusion (40E) and the separable-side stopper protrusion (40D) are provided. The formation of the wide opening (40J) in part of the four sides of the box insert portion (40Z) allows the butterfly pin (30) to be tilted and removed through the opening (40J). Accordingly, when an operation for opening the left and right fastener stringers in the lateral direction is performed by a user, the butterfly pin (30) can be readily removed from the box (40B) with little force.

Description

technical field [0001] The present invention relates to a structure of a plug-in-separator used for a quick-open slide fastener capable of quickly separating closed left and right fastener stringers. Background technique [0002] Conventionally, there have been provided a plug-in-separation element and a slide fastener having the same. The plug-in-separation element is configured to include element rows connected to one side edges of fastener stringers arranged on the left and right. The lower end of the seat tube, socket and intubation. If washing is carried out with the insertion tube inserted in the socket of the zipper of the band plug-separator, the force of compression during washing acts on the plug-separated part, causing damage to the socket and the like. [0003] In order to prevent this socket from being damaged, Patent Document 1 discloses a zipper insertion-separation part, which constitutes the socket by a flexible elastic body, and forms the insertion part of...
