Benefits of technology

The present invention is a type of zip fastener that makes it easier to slide the zipper slider and allows for the addition of a visual indicator. This allows for easy customization and improved visual awareness.

Problems solved by technology

However, when the user pulls the zipper slider, the transverse pulling force that is applied to the two series of interlocking teeth can stretch the junction between each zipper tape and the respective series of interlocking teeth, leading to sliding instability of the zipper slider.
Further, when the zipper slider is sliding on the zipper tapes, the soft zipper tapes can be forced to curve and to project into the inside of the zipper slider, causing the zipper slider to get stuck.

Embodiment Construction

[0015]Referring to FIGS. 1-7, a zip fastener with augmented indication in accordance with the present invention is shown. The zip fastener comprises interlocking teeth 1, a zipper slider 2 and a pair of zipper tapes 3. The interlocking teeth 1 are respectively affixed to one side edge of each of the zipper tape 3 in a staggered manner using injection molding technology. Each interlocking tooth 1 comprises a tooth body 11, a front engagement end piece 12 extended from a front side of the tooth body 11, and a rear extension end piece 13 extended from an opposing rear side of the tooth body 11. The rear extension end piece 13 comprises a track 131 and an augmented portion 132. The track 131 of the rear extension end piece 13 of the interlocking tooth 1 comprises a smooth track base 1311 with a reduced thickness, an upright sliding support wall 1312 located at one lateral side of the smooth track base 1311 and formed integral with the rear side of the tooth body 11, and a L-shaped space...

Abstract

A zip fastener consisting of two zipper tapes, two series of interlocking teeth and a zipper slider is disclosed. Each interlocking tooth includes a front engagement end piece and a rear extension end piece respectively extended from a tooth body thereof in reversed direction. The rear extension end piece provides a track for supporting and guiding sliding movement of the zipper slider and an augmented portion that exhibits a visual indication.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to zip fastener technology and more particularly, to a zip fastener with augmented indication, which uses specially designed interlocking teeth to enhance its clamping stability with the zipper tapes, wherein the rear extension end piece that extends from the rear side of each interlocking tooth comprises a track for supporting and guiding sliding movement of the zipper slider and an augmented portion that exhibits a visual indication. Further, the track comprises a smooth track base with a reduced thickness, an upright sliding support wall located at one lateral side of the smooth track base, and a L-shaped space defined between the smooth track base and the upright sliding support wall such that the upright side flanges of the bottom clamping panel of the zipper slider are movable in the L-shaped space for direct contact with the smooth track base and upright sliding support wall of the track o...
