Slider insert for slide fastener

Abstract

Provided is a slider insert for a slide fastener, the slider insert simplifying the structure for making any one of a pair of right and left pin members engageable with a box, capable of reducing the size of a slider insert compatible with right and left specs, and capable of improving the operability of an operation part. The slider insert comprises a first pin member (11) and a second pin member (12), and a box (13) which has a space (20) and into / from which the first and second pin members (11, 12) can be inserted / extracted. The first and second pin members (11, 12) each have a locking pawl (23). A bottom wall (19) of the box (13) includes a bearing part (28) in communication with the space (20). The slider insert further comprises: pin extraction preventing means (32) that is disposed in the center of the space (20) and is engaged with the locking pawl (23) to prevent the first and second pin members (11, 12) from being extracted simultaneously; an operation part (30) disposed on the side of a bottom surface (19a) of the box (13) and capable of rotatably operating the pin extraction preventing means (32); and a rotating member (14) rotatably fitted to the bearing part (28).

Description

technical field [0001] The present invention relates to a separation insert for a slide fastener. More specifically, it relates to a separation insert for a slide fastener which allows either one of a pair of left and right fastener stringers to be freely separated from a socket. Background technique [0002] Conventionally, there is known a separation insert for separating the left and right fastener stringers after the slider of the slide fastener is slid to the lowest position. The separate insert is configured as follows: for example, a seat tube is provided integrally with the socket at the lower end of the fastener stringer on the right side in a front view, and the insertion tube installed at the lower end of the fastener stringer on the left side can be freely inserted and removed from the socket. In the slide fastener having this separation insert, when the left and right fastener stringers are to be separated from each other, the left fastener stringer is pulled up...

AI Technical Summary

Problems solved by technology

[0006] However, although the slide fastener disclosed in Patent Document 1 discloses a structure in which the movable pin extraction preventing mechanism is moved while the first pin member and the second pin member are inserted and extracted, it is difficult to achieve this due to the complicated structure in the socket. miniaturization

In addition, although the structure in which the operation part for operating the pin extraction preventing mechanism is arranged on the front or back of the socket is disclosed, since the operation part is only arranged on either the front or the back of the socket, it is difficult for the user to grasp the operation part. location, operability may not be good
