In at least a part of a movable range of a slider, a slider upper portion is positioned adjacent to a wall upper portion, and a slider lower portion is positioned adjacent to a wall lower portion. This prevents jamming of a cloth in the slider at both sides of the tape upper and lower surfaces.
Claims19
A slide fastener comprising:
- a pair of fastener stringers including a fastener tape and a fastener element arranged on a side-edge of the fastener tape, the fastener tape having tape upper and lower surfaces defining a tape thickness;
- and
- a slider to be moved to open or close the pair of fastener stringers, the slider including a slider upper portion arranged at a same side as the tape upper surface, a slider lower portion arranged at a same side as the tape lower surface, and a connecting portion connecting the slider upper portion and the slider lower portion,
- wherein:
- at least one fastener tape is provided with a flexible wall configured to prevent jamming of a cloth, the flexible wall being arranged to be spaced apart from the fastener element, the flexible wall including a tubular structure of the fastener tape and a core enclosed in the tubular structure, the tubular structure including warp threads, the warp threads including a warp thread having a thickness greater than a thickness of a weft thread in the fastener tape,
- the flexible wall includes a wall upper portion arranged at the same side as the tape upper surface and protruding from the tape upper surface, and a wall lower portion arranged at the same side as the tape lower surface and protruding from the tape lower surface, and
- in at least a part of a movable range of the slider, the slider upper portion is positioned adjacent to the wall upper portion and the slider lower portion is positioned adjacent to the wall lower portion, the slide fastener being configured to prevent jamming of a cloth in the slider at both sides of the tape upper and lower surfaces.
