Slide fastener with separable bottom end stop

摘要

The slide fastener has a separable bottom end stop, and the separable bottom end stop has at least an insert pin and a box pin. The insert pin has an escape portion provided with an inclined surface or a curved surface along which the thickness dimension of the insert pin 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, the corner portion being positioned along the edge that faces the box pin. This allows the escape portion of the insert pin to function as an interference prevention means, efficiently prevent chain failure in an element row when the slide fastener is bent into a U-shape, and maintain stable engaging.

主权项

1. A slide fastener with separable bottom end stop comprising:
a pair of first and second fastener stringers in which having element rows are disposed wherein a plurality of fastener elements made of synthetic resin are molded along a tape length direction at predetermined intervals at facing respective tape side edges of first and second fastener tapes; and separable bottom end stop disposed to one end of each of the first and second fastener stringers, the separable bottom end stop including:
at least an insert pin attached adjacent to the element row of the first fastener stringer; anda box pin attached adjacent to the element row of the second fastener stringer, wherein at least a corner portion of a front end of the insert pin on a facing side edge side that faces the second fastener stringer includes an escape portion which avoids interference with a fastener element disposed adjacent to the box pin when the fastener elements are coupled, and the escape portion has an inclined surface which declines downward or a concave curved surface, and a thickness dimension of the insert pin in a tape front/back direction gradually decreases continuously from a main body portion towards a front end edge of the insert pin.
