Abstract

An incorporated slide fastener that is incorporated simultaneously with the weaving of the fastener tape for a zigzag-type continuous element. The weft yarn of the fastener tape is woven with one thread traversing and doubling back in the tape width direction, forming a set of two threads. Fastener elements have: engaging heads; first and second leg portions that each extend in the width direction of the tape; first connecting portions that connect first legs that are adjacent in the longitudinal direction of the tape; and second connecting parts that connect second legs that are adjacent in the longitudinal direction of the tape. Of the two yarns configuring the weft yarn, one yarn is woven diagonally straddling the first surface of a first leg and the second surface of a second leg of adjacent fastener elements.

First claim

The invention claimed is:

1. A slide fastener, including:
a pair of left and right fastener tapes, each fastener tape having:
an element attaching portion which is extended in a longitudinal direction along one edge and incorporates and fixes respective fastener elements of a zigzag type continuous element row; and
a tape main body portion which is extended in a width direction of the tape adjacent to one edge of the element attaching portion,

the zigzag type continuous element rows being incorporated into opposing edges of the pair of left and right fastener tapes,
wherein each fastener tape is constituted by a plurality of first fastening warps, a plurality of second fastening warps, and a weft yarn, wherein the weft yarn includes two threads, one constituent thread reciprocates and is weft-inserted in the width direction of the fastener tape in an opening formed among the fastening warps, is returned over at least one of the fastening warps at a tape edge of the element attaching portion side and sequentially reciprocates and is weft-inserted in a subsequent opening,
each of the fastener elements includes an engaging head which is formed from a synthetic resin monofilament and has an engaging portion bulged in a longitudinal direction of the fastener tape in a bending portion bent in a U shape, first and second leg portions which are extended in the width direction of the fastener tape on a first surface and a second surface of the fastener tape respectively, a first connecting portion which connects the first leg portions adjacent to each other in the longitudinal direction of the tape in parallel to the tape surface, and a second connecting portion which connects the second leg portions adjacent to each other in the longitudinal direction of the tape in parallel to the tape surface,
the first leg portion disposed on the first surface is fastened by intersections of the plurality of first fastening warps and the weft yarn and the second leg portion disposed on the second surface is fastened by intersections of the plurality of second fastening warps and the weft yarn,
the two threads reciprocate and are weft-inserted in parallel and the one constituent thread of the weft yarn diagonally straddles the first surface of the first leg portion by passing between at least some of the plurality of first fastening warps and the first leg portion, and
the one constituent thread of the weft yarn diagonally straddles the second surface of the second leg portion of an adjacent fastener element by passing between at least some of the plurality of second fastening warps and the second leg portion.

2. The slide fastener according to claim 1 , wherein:
in a warp adjacent to the element attaching portion of the tape main body portion,
the one constituent thread of the weft yarn diagonally straddling over the first surface of the first leg portion is incorporated by passing through the second surface side of the adjacent warp, and
the one constituent thread of the weft yarn diagonally straddling over the second surface side of the second leg portion is incorporated by passing through the first surface side of the adjacent warp.

3. The slide fastener according to claim 1 wherein:
a selected first fastening warp of the plurality of first fastening warps on an engaging head side straddles two adjacent first leg portions, and
a selected second fastening warp of the plurality of second fastening warps on the engaging head side straddles two adjacent second leg portions.

4. The slide fastener according to claim 1 , wherein:
the weft yarn is weft-inserted twice between the adjacent fastener elements.

5. The slide fastener according to claim 1 , wherein:
the weft yarn is weft-inserted once between the adjacent fastener elements.

6. The slide fastener according to claim 1 , wherein:
a number of the plurality of first fastening warps and a number of the plurality of second fastening warps is the same.
