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.
Claims9
A slider comprising a slider body in which an upper wing and a lower wing are coupled via a coupling pillar at the front side, the upper wing comprises a pair of upper flanges that are projected toward the lower wing and extend away from a front mouth toward a back mouth of the slider, and a passage being divided by the coupling pillar is provided between the upper wing and the lower wing and is partially defined between the pair of upper flanges, wherein
- at a front part of the upper wing, downward slopes are provided at the both left and right sides of the coupling pillar, each downward slope descending toward the lower wing as extending away from the front mouth toward the back mouth of the slider body, wherein
- at a front part of the lower wing, upward slopes are provided at the both left and right sides of the coupling pillar, each upward slope ascending toward the upper wing as extending away from the front mouth toward the back mouth of the slider body, and wherein
- at each left and right side, the downward slope of the upper wing is steeper than the upward slope of the lower wing.
A slider comprising a slider body in which an upper wing and a lower wing are coupled via a coupling pillar at a front side, the upper wing comprises a pair of upper flanges that are protected toward the lower wing and extend away from a front mouth toward a back mouth of the slider, and a passage being divided by the coupling pillar is provided between the upper wing and the lower wing and is partially defined between the pair of upper flanges, wherein
- at a front part of the upper wing, downward slopes are provided at both left and right sides of the coupling pillar, each downward slope descending toward the lower wing as extending away from the front mouth toward the back mouth of the slider body, wherein
- at a front part of the lower wing, upward slopes are provided at the both left and right sides of the coupling pillar, each upward slope ascending toward the upper wing as extending away from the front mouth toward the back mouth of the slider body, wherein
- at each left and right side, the downward slope of the upper wing is steeper than the upward slope of the lower wing, and wherein
- a distance between top and bottom end points of the downward slope along a first thickness direction of the upper wing is greater than a distance between top and bottom end points of the upward slope along a second thickness direction of the lower wing, the first and second thickness directions being parallel to a direction in which the coupling pillar extends.
