Zipper slide for invisible zip fastener

Abstract

A zipper slide is constructed to include a slide body having a locating hole and a retaining hole, a mount integral with the slide body at the top, a pull-tab, the pull tab having a coupling hole pivotally coupled to pivot holders of the mount, and a spring member inserted through the coupling hole of the pull-tab and connected between the locating hole and retaining hole of the slide body to hold down the pull-tab, the spring member having a pointed rear end inserted through the retaining hole of the slide body for engaging the interlocking teeth of the zipper tapes in which the zipper slide to stop the zipper slide from displacement when the pull-tab turned to a horizontal position in parallel to the slide body.

What the invention claimed is:  
     
         1 . A zipper slide installed in two zipper tapes and moved to close/open interlocking teeth of said zipper tapes, comprising: 
 a slide body, said slide body comprising a bottom panel, two sidewalls located on said bottom panel at two opposite lateral sides, a partition block located on said bottom panel on the middle between said sidewalls, and two sliding ways defined between said sidewalls and separated by said partition block for receiving the interlocking teeth of a pair of zipper tapes, said partition block having a locating hole and a retaining hole in a top side thereof;    a mount fixedly located on said partition block of said slide body, said mount comprising a recessed portion and a coupling structure, said coupling structure being comprised of pivot holders symmetrically provided at two opposite lateral sides of said recessed portion;    a pull-tab, said pull-tab having a coupling hole pivotally coupled to said pivot holders of said mount; and    a spring member set in the recessed portion of said mount and inserted through the coupling hole of said pull-tab, said spring member having a first end fastened to the locating hole of said slide body and a second end inserted into the retaining hole of said slide body.    
     
     
         2 . The zipper slide as claimed in  claim 1 , wherein said sidewalls of said slide body have a substantially  -shaped profile and define with said mount and said partition block said sliding ways.  
     
     
         3 . The zipper slide as claimed in  claim 1  wherein said sidewalls of said slide body have a substantially L-shaped profile and define with mount and said partition block said sliding ways.  
     
     
         4 . The zipper slide as claimed in  claim 1  wherein said mount is formed integral with said partition block of said slide body.  
     
     
         5 . The zipper slide as claimed in  claim 1  wherein said spring member has an invertedly disposed T-shaped anchoring portion extended from the first end thereof and fastened to the locating hole of said slide body, and a pointed locating portion extended from the second end there and inserted into the retaining hole of said slide body and adapted to engage interlocking teeth of the zipper tapes in which the zipper slide is installed to stop the zipper slide from displacement relative to the zipper tapes when said pull-tab set in a horizontal position in parallel to said slide body.
