A zipper with at least one curve includes a first tape and a second tape, and interlocking elements attached to the first tape and the second tape, wherein the first tape and the second tape are curved, and wherein a curve of at least one of the tapes was caused by compaction of that tape.

Curved zippers

A waterproof zipper with at least one curve includes a first tape and a second tape, and interlocking elements attached to the first tape and the second tape, wherein the first tape and the second tape are curved, and wherein a curve of at least one of the tapes was caused by compaction of that tape. The zipper is coated on at least one side with a fluid impervious coating.

Waterproof curved zippers

A zip slider has: a slider body having upper and lower elements providing two entry channels through which zip teeth pass and slider un/mating; a pull tab having a cam; a biasing spring having a locking prong and a follower surface bearing against the cam. The cam on the follower surface biases the tab into a closed position in which it lies against the upper element. When the tab is in a lifted position, the cam action on the follower surface raises the prong above the mated teeth, enabling relative motion of the teeth and body; when the tab is in the closed position, the prong bears against the teeth to prevent unwanted relative slider and teeth motion. The slider has a counter bias, acting between the upper element and the tab to apply a biasing force on the tab acting against the action of the cam and follower surface.

Zip slider

A zip fastener comprises two opposing and mutually engageable rows of zip teeth each being mounted upon a respective stringer tape; first and second sliders movably mounted upon the teeth, each slider being movable forward along the teeth to cause interdigitation of the teeth thereby to fasten the zip and backwards to cause extradigitation and unfastening of the zip, the sliders being mounted on the teeth in opposing directions such that motion of the sliders towards and away from each other results in the same action (e.g. fastening or unfastening) on the zip teeth; a docking member, mounted upon the teeth and being movable along the teeth, the docking member being mounted between the two sliders; and each slider being engageable with the docking member thereby to fasten the zip.

Zip fastener

A zip includes: a pair of stringer tapes, each of which supports a row of teeth; the teeth on the two tapes being mutually opposing and capable of interdigitation thereby to fasten one stringer tape to another; a slider, adapted to move along and whose motion is guided by the rows of teeth, the slider being adapted to cause interdigitation of the teeth as a result of motion along the teeth in a first direction, and to disconnect the teeth by motion along the teeth in a second direction; wherein the first and second stringer tapes are formed of a matrix of threads interspersed with a waterproof material.
