Abstract
A slide fastener includes: a pair of fastener stringers each provided with a fastener element at a bent side-edge portion of a fastener tape; a slider that moves for opening or closing the pair of fastener stringers; and a pair of resin-made terminal members each fixed to the fastener tape adjacently to the fastener element in a terminal portion of the fastener tape in an elongation direction of the fastener tape, the pair of terminal members including a pin and a socket configured to receive the pin. Reinforcing films are attached to both tape surfaces of at least one fastener tape in the terminal portion, and each reinforcing film has an embedded portion embedded in the terminal member.
Claims18
A slide fastener comprising:
- a pair of fastener stringers, each of the pair of fastener stringers including a fastener tape and a fastener element, the fastener tape including a tape main portion and a bent side-edge portion, the bent side-edge portion including a bent portion and an attachment portion, an interspace being formed between the tape main portion and the attachment portion, and the fastener element being secured to the attachment portion;
- a slider that moves for opening or closing the pair of fastener stringers;
- a pair of resin-made terminal members comprising a pin and a socket configured to receive the pin, each of the pin and the socket being fixed to the fastener tape adjacently to the fastener element in a terminal portion of the fastener tape in an elongation direction of the fastener tape, and each of the pin and the socket comprising a bar fixed to the bent side-edge portion, a flange fixed to the tape main portion, and a groove formed between the bar and the flange and in spatial communication with the interspace;
- and
- reinforcing films attached to both tape surfaces of at least one of the fastener tapes in the terminal portion, each of the reinforcing films having an embedded portion embedded in the flange of at least one of the terminal members.
A method of producing a slide fastener comprising:
- attaching reinforcing films to both tape surfaces of at least one fastener tape in a space portion of a fastener chain where a fastener element is partially removed, the fastener chain including a pair of fastener stringers each provided with the fastener element at a bent side-edge portion of a fastener tape;
- forming a through-hole that penetrates through at least the fastener tape in the space portion;
- and
- forming a resin-made terminal member fixed to the fastener tape adjacently to the fastener element in the space portion, the terminal member being a pin or a socket, wherein
- the terminal member is formed such that each reinforcing film has an embedded portion embedded in the terminal member.
