Abstract

A slide for a slide fastener capable of separately inserting and removing any of a first pin member and second pin member into and from a box body is provided. Locking claws (31, 231, 1031, 1131, 1231; 41,241, 1041, 1141, 1241) are formed on first pin members (30, 230, 1030, 1130, 1230) and second pin members (40, 240, 1040, 1140, 1240) which are constructed so as to be capable of being inserted and removed into and from box bodies (50, 150, 250, 350, 450, 550, 650, 750, 850, 1050, 1150, 1250) of slides for slide fasteners (22, 322, 422, 522, 622, 722, 822, 1022, 1122, 1222). Further, movablepin extraction blocking means (68, 268, 1068, 1168, 1268) for blocking simultaneous extraction of both of the first and second pin members (30, 230, 1030, 1130, 1230; 40, 240, 1040, 1140, 1240) are arranged in the center of space portions (57, 257) in the box bodies (50, 150, 250, 350, 450, 550, 650, 750, 850, 1050, 1150, 1250) by being engaged with the locking claws (31, 231, 1031, 1131, 1231; 41,241, 1041, 1141, 1241).

Description

technical field [0001] The present invention relates to a separation and insertion device for an open slide fastener that can separate left and right fastener stringers after sliding a slider of the slide fastener to the lowest part to open the slide fastener, and a slide fastener having the separation and insertion device. Background technique [0002] Conventionally, after sliding the slider of a slide fastener to the lowest part, the separation|separation interfitting device for separating the fastener element chains on either side is well-known. The separation and insertion device generally used in the prior art, for example, when viewed from the front, a box rod integrated with the box body is provided at the lower end of the zipper chain on the right side, so that the first pin member installed at the lower end of the zipper chain on the left side It can be freely inserted and removed relative to the box body. In the slide fastener with the separating interfitting dev...
