Abstract
Abstract A slide fastener slider having on its upper wing a hook-shaped lug to which a pull tab is pivotally connected by snap fitting operation. There is also provided on the upper wing a projection spaced apart from the lug and adapted to fit in an opening formed in the pull tab when the latter is moved down into contact with the slider upper wing, thereby preventing the pull tab from becoming displaced relative to the horizontal axis of the slider body.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
A slide fastener slider comprising: an upper and a lower wing interconnected at one end by a neck portion; a hook-shaped lug integral with and projecting upwardly from said upper wing and terminating in a free end bent downwardly toward and in opposed relation to the top surface of said upper wing; a pull tab having an elongate opening and a transversely extending pintle pivotally connected to said lug; and a projection extending upwardly from said upper wing and spaced from and in opposed relation to said free end of the lug by a gap sufficiently large to admit said pintle, said projection being adapted to engage with said opening when the pull tab is moved into contact with said top surface of the upper wing, thereby preventing said pull tab from becoming displaced relative to the longitudinal axis of the slider.
Claim 2
Dependent Claim
