Abstract
Disclosed is a slider for a slide fastener having a flexible upper wing piece and lower wing piece, and configured in such a way that zipper teeth are thrust into a tape insertion passage when a lateral pulling force is applied to a left and right pair of first and second fastener stringers. Accordingly, the application of a lateral pulling force to the left and right first and second fastener stringers results in the expansion of the width of the tape insertion passage of the slider and the separation of the zipper tooth rows. Thereupon the first and second fastener stringers which are engaged can be readily switched to a disengaged state.
Claims7
A slider for a slide fastener through which first and second zipper teeth rows attached to edges of a pair of first and second (left and right) fastener stringers facing each other are inserted and which switches the first and second zipper teeth rows to an engaged or disengaged state, the slider comprising:
- upper and lower wing pieces;
- a connection post that is disposed in the middle of left and right shoulder mouths and connects the upper wing piece with the lower wing piece;
- and
- a flange that extends from a side edge of at least one of the upper and lower wing pieces toward the opposite wing piece,
- wherein a tape insertion passage where a fastener tape of each of the first and second fastener stringers is inserted and guided is formed at an end edge of the flange, and
- at least one of the upper and lower wing pieces is bent, so that the width of the tape insertion passage is increased.
