Zipper head structure

Abstract

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.

1 . A zipper head structure, comprising:
 a slider body having an assembling surface, wherein an extension is formed on one end of the assembling surface and a ridge is formed on the assembling surface near the extension;   a pull-tab having a holding portion on one end and an opening formed on another end thereof, a hinge portion being defined between the opening and the corresponding end of the pull-tab, the hinge portion being on the opposite end of the holding portion, wherein the pull-tab is disposed on the assembling surface of the slider body, wherein the extension of the slider body is arranged in opening of the pull-tab, and wherein the hinge portion is disposed between the ridge and the extension; and   a locking hook having a base portion disposed over the hinge portion of the pull-tab on the assembling surface of the slider body, thereby retaining the pull-tab on the slider body.   
     
     
         2 . The zipper head structure of  claim 1 , wherein the slider body further comprises a slot and a joining portion formed thereon, wherein the slot projects through the slider body and is formed on one end of the slider body, and wherein the joining portion is formed on another end of the slider body opposite of the slot. 
     
     
         3 . The zipper head structure of  claim 2 , wherein a hooking portion is formed by bending one end of the base portion, and wherein a fixing portion is formed by bending another end of the base portion. 
     
     
         4 . The zipper head structure of  claim 3 , wherein the hooking portion of the locking hook projects through the slot of the slider body. 
     
     
         5 . The zipper head structure of  claim 3 , wherein the fixing portion is secured to the joining portion of the slider body. 
     
     
         6 . The zipper head structure of  claim 4 , wherein the joining portion is concaved. 
     
     
         7 . The zipper head structure of  claim 1 , wherein a mouth is formed in between the base portion and the hooking portion of the locking hook, and wherein the extension of the slider body projects through the mouth of the locking hook. 
     
     
         8 . The zipper head structure of  claim 1 , wherein the slider body is integrally formed.
