Abstract
A fastening system for a zipper is disclosed which includes locking or interlocking first and second zipper pull tabs. A first zipper pull tab comprises a first base, a hook extending from the first base, and a moveable gate coupled to the first base. A second zipper pull tab comprises a second base, a cover coupled to the second base, and a post extending between the second base and the cover. For interlocking, the moveable gate and hook are further coupled around the post to provide the interlocking configuration of the first and second zipper pull tabs. The first zipper pull tab may be utilized separately from the second zipper pull tab, such as to lock to a coupling ring or another component of a carrying bag.
Claims18
A zipper pull tab coupleable to a zipper slider for a zipper, the zipper pull tab comprising:
- a base having a first side and a second side opposite the first side, the base comprising a first recess extending into the base from the second side, wherein the base is flat and has a first thickness;
- a hook integrally formed with and extending from the base on the second side, the hook comprising an elongated rectilinear portion coplanar with the base and a C-shaped curvature coplanar with the base and terminating in a hook end;
- a moveable gate having a first gate end and a second gate end, the second gate end arranged at least partially inside the first recess, the moveable gate extending from the first recess coplanar with the hook and the base, the moveable gate pivotably coupled inside the first recess, the moveable gate and hook forming a first interior region of the zipper pull tab, and the moveable gate pivotable into the first recess and the first interior region;
- and
- a C-shaped coupling integrally formed with and extending from the first side of the base for coupling to the zipper slider, the C-shaped coupling having a thickness tapering from the first thickness at the first side of the base to a second thickness at a first end of the zipper pull tab, the first thickness greater than the second thickness, wherein a ratio of the first thickness to the second thickness is between 4:1 to 2:1.

A zipper pull tab coupleable to a zipper slider for a zipper of a carrying bag, the zipper pull tab comprising:
- a flat base having a first thickness, the base having a first side and a second side opposite the first side, the base comprising a first recess extending into the base from the second side;
- a hook integrally formed with and extending from the second side of the base, the hook comprising an elongated rectilinear portion coplanar with the base and a C-shaped curvature coplanar with the base and terminating in a hook end;
- a moveable gate having a first gate end and a second gate end, the second gate end arranged at least partially inside the first recess, the moveable gate extending from the first recess coplanar with the hook and base, the moveable gate and the hook forming a first interior region of the zipper pull tab, the moveable gate pivotably coupled inside the first recess and pivotable into the first recess and the first interior region;
- a C-shaped coupling integrally formed with and extending from the first side of the base for coupling to the zipper slider, the C-shaped coupling having a thickness tapering from the first thickness at the first side of the base to a second thickness at a first end of the zipper pull tab, the first thickness greater than the second thickness, wherein a ratio of the first thickness to the second thickness is between 4:1 to 2:1;
- and
- a grip integrally formed with the moveable gate, the grip spaced apart from the first gate end and extending transversely from the moveable gate opposite from the first interior region.
