Abstract

Zip fastener, characterized in that it comprises: (a) a pair of flexible support tapes carrying elastic fringes at and along their respective inner longitudinal edges; (b) two rows of individual coupling elements mounted on and along said marginal cords (or) a slider mounted slidably on said rows of coupling elements and adapted to slide back and forth along said rows of interengaging coupling elements. To join or separate them to close or open said slide fastener, said slider having a flared front end and a narrow rear end and including a neck portion formed in the center of said flared front end and a pair of opposite side tabs formed in both of its sides to define between them a Y-shaped channel for the reciprocating sliding passage of said rows of coupling elements therethrough; and (d) a lower end stop attached to said marginal cords at one end of said rows of intermeshing coupling elements, said lower end stop including a first element mounted on a first bead and adapted to cooperate at its top with the bumper element. Lowermost interengaging coupling carried by the other bead, a second element mounted on said first bead at a given distance below said bead. First element and a third element mounted on said other cord at a distance given below said lowermost coupling element and arranged in opposite relation to the lower part of said first element and said second element, said third element being adapted to cooperate in its upper part with said first element in order to slide transversely with respect to the plane of said slide fastener and along said plane and to cooperate with its lower part with said second element in order to pivot by the plane of said slide fastener, said third element having the general shape of a polygon comprising an inner side that is inwardly of said other cord, an outer side that is outwardly of said other cord, an upper inner corner adjacent said inner side and an upper outer corner contiguous to said outer side, said third element being provided adjacent to said upper interior corner. A stop for cooperation of bumping with said neck part of said cursor, said upper inner corner being above said upper outer corner in order to leave said elastic cord intact next to it, the dimension of said third element being measured perpendicularly next to said neck part as arranged when it passes between said side of said neck part and said corresponding flange, slightly smaller than the distance between said side of said neck part and said corresponding flange.
