Fastener stringer

摘要

A fastener stringer is provided with a fixing section in which at least one of a first and second half sections is fixed to a fastener tape and a tapered extending section which extends from the fixing section toward the outside of the tape. A first side face and a second side face in the tape length direction in the fixing section have concave surfaces which curve in a concave shape so as to gradually increase from an element surface of a fastener element toward the fastener tape. Accordingly, each fastener element can exhibit an appearance close to a metallic fastener element and a locking mechanism of a slider can be made to function stably.

主权项

1. A fastener stringer including a fastener tape, and a plurality of fastener elements made of synthetic resin, which are attached to a tape side edge section of the fastener tape, in which
the fastener elements include a first half section which is disposed on a first surface side of the fastener tape and a second half section which is disposed on a second surface side of the fastener tape, and in which at least one of the first and the second half sections has a tapered element shape comprising a fixing section fixed to the fastener tape and an extending section extending from the fixing section past the tape side edge of the tape and gradually decreasing in an element width dimension in a tape length direction toward a tip end section,wherein
a width dimension from a first side face to a second side face in the tape length direction of the fixing section gradually increases from an element surface of the fastener element toward a tape surface of the fastener tape, and each of the first side face and the second side face in the fixing section has a curved concave surface, which curves inward so that the width dimension of the fixing section gradually increases between curves formed by the concave surfaces of the first side face and the second side face from the element surface toward a tape surface of the fastener tape.
