Abstract
Slide fasteners configured such that opposing elements engage with one another in a non-planar relationship. The elements may engage one another, for example but not limited to, at an angle between approximately 60 degrees and approximately 179 degrees. In some embodiments, each element includes a head and at least one shoulder with angle keeping surfaces and engagement surfaces that abut corresponding surfaces when engaging with a corresponding element to interlock the heads and shoulders of opposing elements. Slide fasteners of the invention may be well suited for use with curved surfaces, corners, ridge lines, edges, or the like of an article.
