Slide fastener slider

Abstract

A slider ( 1 ) for a slide fastener comprises a slider body ( 2 ) having a mounting hole ( 13 ) formed therethrough; an attaching pole ( 4 ) having a pin hole ( 21 ) formed at the upper end to extend laterally therethrough. The attaching pole ( 4 ) is upwardly inserted through the mounting hole ( 13 ) with its pin hole ( 21 ) lying beyond the upper surface of the slider body ( 2 ). A pull tab ( 3 ) has two attachment lugs ( 25 ) formed at its proximal end and provided with their respective pin apertures ( 26 ). A pin ( 5 ) is inserted into the pin hole ( 21 ) of the attaching pole ( 4 ) and the pin apertures ( 26 ) of the pull tab ( 3 ), so that the pull tab ( 3 ) is pivotally mounted on the attaching pole ( 4 ). The slider ( 1 ) may have a shock-absorbing member ( 50 ) made of soft materials and mounted on the pull tab ( 3 ) at the region where the pull tab ( 3 ) contacts the slider body ( 2 ) in order to prevent the pull tab ( 3 ) from causing rattling noises.

1 . A slider reciprocally mounted on a slide fastener chain, comprising: 
 a slider body including a guidepost having a mounting hole formed therethrough; an attaching pole having a large-diametered portion formed at its one end and having a pin hole formed at the other end so as to extend laterally therethrough; the attaching pole inserted upwardly through the mounting hole and rotatably mounted on the slider body with the pin hole lying beyond the upper surface of the slider body; a pull tab including a grip portion and two attachment lugs formed by bifurcating the proximal end of the pull tab, the attaching lugs having their respective pin apertures formed in alignment with each other; and a pin inserted into the pin hole of the attaching pole and the pin apertures of the pull tab, so that the pull tab is pivotally mounted on the attaching pole.    
   
   
       2 . A slider recited in  claim 1 , wherein the mounting hole has a countersink formed on its lower end.  
   
   
       3 . A slider recited in  claim 1 , wherein the mounting hole has countersinks formed on the upper and lower end, respectively thereof.  
   
   
       4 . A slider recited in  claim 1 , wherein a raised rim is formed around the mounting hole on each of the upper and lower surface of the slider body.  
   
   
       5 . A slider recited in  claim 1 , wherein the pin is cylindrical and has a slit formed axially throughout its length, and the pin hole has a narrowed portion formed at its middle in the shape of an inner projection projecting inward from its inner surface so as to fasten pin through its own resiliency.  
   
   
       6 . A slider recited in  claim 1 , wherein the slider body has a flat lower surface, and the large-diametered portion being in the shape of a thin disk which is flat at its inner and outer surfaces so that the large-diamtered portion is adapted to intimately contact the lower surface of the slider body.  
   
   
       7 . A slider recited in  claim 1 , wherein the mounting hole is in the shape of a truncated cone, and the attaching pole is complementarily in the shape of a truncated cone.  
   
   
       8 . A slider recited in  claim 1 , wherein, as viewed in the profile, the pull tab is bent obtusely at a bent portion which is adjacent to the attachment lugs.  
   
   
       9 . A slider recited in  claim 1 , wherein an additional slider is reciprocally mounted on the fastener chain, so that the two sliders are disposed reversely to each other on the fastener chain, the pull tab of one slider being bent obtusely at a bent portion which is adjacent to the attachment lugs in reverse direction relative to the pull tab of the other slider, each pull tab having a through hole formed therethrough adjacent to its distal end, so that when both sliders come into abutting engagement to each other to close the slide fastener chain, said one pull tab can be turned over flat against said other pull tab, with their respective through holes in registry with each other.  
   
   
       10 . A slider recited in  claim 1 , wherein the slider body and pull tab are made of hard material; the slider further including a shock-absorbing member made of soft, material and mounted on the pull tab at its region where the pull tab contacts the slider body, so as to bulge on both upper and lower surfaces of the pull tab.  
   
   
       11 . A slider recited in  claim 10 , wherein the shock-absorbing member is mounted on the grip portion of the pull tab.  
   
   
       12 . A slider for a slide fastener recited in  claim 10 , wherein the grip portion has a recess formed therein adjacent to the attachment lugs, and a plurality of small through holes formed through the grip portion within the recess; the shock-absorbing member being mounted in the recess.  
   
   
       13 . A slider recited in  claim 9 , the slider body and pull tab of each slider are made of hard material each slider further including a shock-absorbing member made of soft material and mounted on the pull tab at the region where the pull tab contacts the slider body, so as to bulge on both upper and lower surfaces of the pull tab.
