Zipper slide

Abstract

A zipper slide is adapted to a zipper on a shoe for simultaneously combining/separating two zipper tapes of the zipper and fastening/loosing two laces of the shoe. The zipper slide includes a slide body, a pull tab, a bottom cover and a gripping block. The slide body has two guiding grooves providing for the two zipper tapes of the zipper, respectively. The pull tab is coupled to the slide body. The bottom cover is assembled to a bottom portion of the slide body. Two tracks are defined between the bottom cover and the slide body. A space is positioned between the two tracks. A gripping block is forward/backward movably arranged in the space. The gripping block has two gripping surfaces at two sides thereof. The two gripping surfaces are respectively extended into the two tracks thereby to grip the laces passed through in the tracks.

1 . A zipper slide adapted to a zipper on a shoe for simultaneously combining/separating two zipper tapes of the zipper and fastening/loosing two laces of the shoe, comprising: 
 a slide body having two guiding grooves providing for the two zipper tapes of the zipper, respectively;    a pull tab coupled to the slide body;    a bottom cover assembled to a bottom portion of the slide body to define two tracks therebetween and a space positioned between the two tracks; and    a gripping block forward/backward movably arranged in the space, the gripping block having two gripping surfaces at two sides thereof, and the two gripping surfaces respectively extending into the two tracks thereby to grip the laces passed through in the tracks.    
   
   
       2 . The zipper slide of  claim 1 , wherein the bottom cover is assembled to the bottom portion of the slide body by rivets, the gripping block has a sliding slot at a middle portion thereof for providing at least one of the rivets to pass through, an elastic element has two ends respectively abutting against one rivet in the sliding slot and a wall adjacent to the sliding slot, so that the gripping block is elastically positioned in the space.  
   
   
       3 . The zipper slide of  claim 1 , wherein the two tracks are gradually approached to each other from front to rear thereof.  
   
   
       4 . The zipper slide of  claim 1 , wherein the gripping block has an adjusting portion formed at one end thereof, and the adjusting portion is extended out the slide body and the bottom cover.  
   
   
       5 . The zipper slide of  claim 1 , wherein the gripping block is of a wedge shape.  
   
   
       6 . The zipper slide of  claim 1 , wherein each of the two gripping surfaces of the gripping block is of a sawtooth shape.  
   
   
       7 . The zipper slide of  claim 1 , further comprising a spring plate arranged on the slide body, the spring plate having a retaining portion extended into the guiding grooves of the slide body, a connecting element connected to on a top portion of the slide body, the connecting element abutting against an inner edge of the spring plate, the pull tab coupled to the connecting element, and a hooking means defined between the slide body and the pull tab for hooking the pull tab on the slide body.  
   
   
       8 . The zipper slide of  claim 7 , wherein the slide body has an accommodated space for accommodating the spring plate and a through hole for accommodating the retaining portion of the spring plate.  
   
   
       9 . The zipper slide of  claim 7 , wherein the connecting element has a pivotal shaft at one end thereof, the pivotal shaft is pivotally connected to the top portion of the slide body, and the pivotal shaft abuts against the inner edge of the spring plate.  
   
   
       10 . The zipper slide of  claim 9 , wherein the connecting element has a first pin hole at another end thereof, the pull tab has a second pin hole at one end thereof, and a pin passes through the first pin hole and the second pin hole, so that the pull tab is pivotally connected to an end portion of the connecting element.  
   
   
       11 . The zipper slide of  claim 1 , wherein the pull tab has a top surface providing words, patterns or trademarks thereon.
