20120291236 | ZIPPER HEAD STRUCTURE - A zipper head structure includes a slider body, a pull-tab, and a locking hook. The slider body has an assembling surface for disposing an extension and a ridge. The pull-tab has a holding portion on one end with an opening formed on an opposite end. A hinge portion is defined between the opening and the corresponding end of the pull-tab, with the hinge portion being opposite of the holding portion. The pull-tab is disposed onto the assembling surface of the slider body. The extension of the slider body is received by the opening of the pull-tab. The hinge portion is disposed in between the ridge and the extension. The locking hook is secured to the assembling surface of the slider body. By restricting the movement of the hinge portion, the pull-tab is prevented from separating with the slider body when pulling the zipper. | 11-22-2012 |
