Abstract
A zipper including two stringers, each stringer having a row of coupling elements having a plurality of coupling element spacings, and at least one stringer having a plurality of coupling element widths.
Claims15
A first zipper stringer for use with a second zipper stringer, comprising:
- at least a first coupling element having a first width equal to one half of a first coupling element spacing of a closed zipper having a plurality of coupling elements identical to said first coupling element;
- and
- at least a second coupling element having a second width equal to one half of a second coupling element spacing of a closed zipper having a plurality of coupling elements identical to said second coupling element;
- wherein said first coupling element comprises a substantially rigid first projection that is rotatable relative to adjacent projections;
- wherein said second coupling element comprises a substantially rigid second projection that is rotatable relative to adjacent projections;
- wherein said first zipper stringer is reversibly interlockable with the second zipper stringer;
- and
- wherein said first coupling element spacing is different from said second coupling element spacing;
- whereby the first zipper stringer comprises a first coupling element pitch sequence comprising at least two different coupling element spacings.
