Abstract: A slider for slide fastener has a slider body in which an upper wing and a lower wing are coupled via a coupling pillar at the front side. At the front part of the upper wing, provided is a downward slope descending toward the lower wing as extending away from a front mouth toward a back mouth of the slider body. At the front part of the lower wing, provided is an upward slope ascending toward the upper wing as extending away from the front mouth toward the back mouth of the slider body. The downward slope of the upper wing is steeper than the upward slope of the lower wing.

Abstract: A slider includes lower flanges placed on left and right side edges of a lower wing plate. Each of the lower flanges includes a downwardly inclined surface portion which is placed on the shoulder-opening-side tip portion on a side of its upper surface and on an outer side in a width direction of the slider, and which downwardly inclines toward a shoulder and downwardly inclines toward the outer side in the width direction of the slider.

Abstract: A zipper of the type having two tapes with interconnecting teeth, a slide having a front and rear and including a divider to separate and mesh the teeth in cooperation with a pull tab attached to the slide, includes spaced wing segments formed on the slide in proximity to the front of the slide. The spaced wing segments present a profile at the front or leading edge of the slide, in which the profile takes the form of a plow. The plow-like profile is formed as a beveled surface at the leading edge, and is thus adapted to force extraneous material such as threads, fabric, and the like, away from engagement with the interconnecting teeth when the zipper is zipped to the zipped-up condition. The trailing edge, or rear, of the slide may similarly be beveled to exclude unwanted fabric when the zipper is unzipped.

Abstract: A slide fastener slider includes a pair of parallel spaced wings each having a generally W-shaped front edge extending between a pair of flanges extending along the opposite lateral edges of the wing across a neck interconnecting the wings to define therebetween a substantially Y-shaped guide channel.
