Abstract

The present disclosure relates to a track zipper and a connecting structure having a track zipper. The track zipper includes a first track, a second track, and a zipper core connecting the first and second tracks. The first track and a first side of the zipper core are provided with a first slidably connecting structure. The second track and a second side of the zipper core are provided with a second slidably connecting structure. When the track zipper is in a closed position, a plurality of first and second core elements of the zipper core interlock with a plurality of first and second track elements of the first and second tracks respectively, such that the zipper core is inseparable from the first and second tracks. The track zipper is advantageous in that it can prevent foreign material from being caught by the zipper, and has a much stronger bearing capacity.

Dependent claims

A track zipper comprising:

a first track;
a second track;
a zipper core connecting the first and second tracks;
a plurality of first and second core elements formed along a first and second side of the zipper core respectively and spaced apart in a lengthwise direction of the zipper core;
a plurality of first and second track elements formed along the first and second tracks respectively and spaced apart in a lengthwise direction of the first and second tracks;
and
a plurality of first and second slots defined by the plurality of first and second track elements, the plurality of first and second slots are dimensioned to allow the plurality of first and second core elements to pass therethrough in a direction perpendicular to the lengthwise direction of the first and second tracks respectively,
wherein the plurality of first and second core elements and the plurality of first and second track elements are sized and shaped so that when the track zipper is in a closed position, the plurality of first and second core elements are interlocked with the plurality of first and second track elements respectively, and the zipper core is inseparable from the first and second tracks in the direction perpendicular to the lengthwise direction of the first and second tracks, and
wherein the zipper core is slidable relative to the first and second tracks along the lengthwise direction thereof by a distance of one track element to a position where the plurality of first and second core elements are disengaged from the plurality of first and second track elements respectively, so that the zipper core is detachable from the first and second tracks in the direction perpendicular to the lengthwise direction thereof.
