摘要:
A slide fastener of the present invention includes: a first fastener stringer; a second fastener stringer; and a slider which couples or separates the first and second fastener stringers, in which the second fastener stringer separated from the slider is inserted into the slider wherein the first fastener stringer and the second fastener stringer are coupled in a vertical direction. Accordingly, a row of fastener elements of the second fastener stringer separated from the slider is inserted into the slider by first and second fastening members when a fixing pin and an insertion pin are coupled in a vertical direction, and as a result, the coupling operation is convenient.

A slide fastener (1, 81, 91) according to the invention includes a pair of left and right, first and second fastener stringers (2a, 2b), a box pin (4, 82, 92), an insert pin (5), and a pair of first and second sliders (6a, 6b). The first slider (6a) is arranged closer to the box pin (4, 82, 92) than the second slider (6b). The box pin (4, 82, 92) has a box pin body (41, 83, 93), a stopper portion (42) arranged at a front end side of the box pin body (41, 83, 93), and suppressing portions (43, 84, 94) projected on at least one of upper and lower surfaces of the box pin body (41, 83, 93) to suppress sliding of the second slider (6b). Further, the box pin body (41, 83, 93) has a body region (41a, 83a, 93a), and a notched region (41b, 83b, 93b) arranged at an element-row-side base end portion and having excluded a side surface portion at a side facing the insert pin. The suppressing portions (43, 84, 94) are projected in only the notched region (41b, 83b, 93b). With this arrangement, even when a variation occurs in a size of the box pin (4, 82, 92) or the second slider (6b) when manufacturing the slide fastener (1, 81, 91), the second slider (6b) can be stably held at an insert-pin inserting position without reducing slidability and operability of the second slider (6b), and a subsequent insert operation or extract operation of the insert pin (5) can be smoothly performed.

The slide fastener (1, 2) of the invention has separable bottom end stop (30, 40), and the separable bottom end stop (30, 40) has at least an insert pin (31, 41) and a box pin (32, 42). The insert pin (31, 41) has an escape portion (31b, 41c) provided with an inclined surface or a curved surface along which the thickness dimension of the insert pin (31, 41) decreases in the direction of the tape width toward the side edge that faces the box pin, the escape portion being positioned in the front end corner portion of a first surface of the insert pin (31, 41), the corner portion being positioned along the edge that faces the box pin. This allows the escape portion (31b, 41c) of the insert pin (31, 41) to function as an interference prevention means, can efficiently prevent chain failure in an element row (12) when the slide fastener (1, 2) is bent into a U-shape, and can maintain stable engaging.

The invention provides a bottom end stop for a slide fastener having a sufficient strength and an excellent appearance to see, wherein bottom ends of fastener stringers (3a, 3b) provided with a first member (11) and a second member (21) are inserted through shoulder mouths (4b) of a slider (4) ; the first member (11) and the second member (21) slide along flanges (6a, 6b) of the slider (4) respectively; while the first member (11) and the second member (21) are rotated in the direction of approaching each other, coupling of a pair of coupling heads (12a, 12b) and coupling concave portions (24a, 24b) formed on opposing faces of the first member (11) and the second member (21) can be carried out, and also coupling of coupling heads (22a, 22b) and coupling concave portions (14a, 14b) can be carried out; and further, by setting the length of the second member (21) having no engaging portion with a fastener element to be shorter than the length of the first member (11), rotation of the first member (11) and the second member (21) can be carried out smoothly.

As a pair of fastener tapes (1) is supplied through a molding machine (4) and then through a fiber hardening agent applying and impregnating unit (5), a predetermined length of coupling element rows (6) are molded on and along confronting beaded edges of the fastener tapes (1), and simultaneously a separable bottom stop assembly (7) composed of a pin member (7a) and a box member (7b) and top stops (8) are molded about one ends and the other ends of the coupling element rows (6), whereupon a fiber hardening agent (9a) is applied over and impregnated in the tape surfaces of the prospective bottom end portions by the fiber hardening agent applying and impregnating unit (7).
