Abstract
Abstract The bottom wing of the slider body has a pair of lateral extensions which are angled toward the top wing. When the slide fastener including this slider is attached to an article such that the opening therein is bounded by one or two pairs of edges disposed in opposed or abutting relationship, the lateral extensions from the bottom wing serve as guide members to raise the rear edge portions of the respective stringer tapes out of the plane of their element-carrying front edges. Since the article edges are thus held over, and under, the slider body, they are prevented from becoming caught between the top and bottom wings of the slider body during slider movement along the fastener elements.

Claim 1
Independent Claim
212 words
In a slide fastener of the type having a pair of opposed stringer tapes and respective rows of fastener elements disposed along confronting edges of said stringer tapes, and a slider moveable along said rows of fastener elements to selectively open and close the slide fastener, said slider having a top wing, a bottom wing and means connecting said top and bottom wings to define a generally Y-shaped guide channel through said slider accommodating the passage of said rows of fastener elements, the improvement which comprises one of said wings having opposing lateral extensions defining guide members each directed at an inclination with respect to the other wing and engaging a corresponding stringer tape to hold said stringer tape in an offset configuration whereby the edge portion of the stringer tape remote from the row of fastener elements thereof is in a plane displaced from the row of fastener elements to prevent intrusion into the guide channel of other material attached to the stringer tape, the bottom wing having said guide members and including on said slider a pair of side flanges downwardly directed and formed along respective marginal edges of said top wing, and the bottom edges of said side flanges being disposed below the top edges of said guide members.
