Slide Fastener

Abstract

A slide fastener fastens separated portions of one or more outer material. A pair of fastener tapes includes a pair of main body portions, and a pair of folded portions formed by folding each of opposite inner ends of the pair of main body portions in substantially U-shape. A pair of elements are attached to the pair of folded portions. A slider engages and disengages the pair of elements. The pair of main body portions are sewn to the outer material at positions inner than outer ends of the pair of elements in a width direction of the slide fastener.

1 . A slide fastener that fastens separated portions of one or more outer material, the slide fastener comprising:
 a pair of fastener tapes including a pair of main body portions, and a pair of folded portions formed by folding each of opposite inner ends of the pair of main body portions in substantially U-shape;   a pair of elements attached to the pair of folded portions; and   a slider that engages and disengages the pair of elements,   wherein the pair of main body portions are sewn to the outer material at positions inner than outer ends of the pair of elements in a width direction of the slide fastener.   
     
     
         2 . The slide fastener as set forth in  claim 1 , further comprising a pair of covering tapes attached to the pair of elements,
 wherein the slide fastener is attached to the outer material such that the covering tapes are exposed to the outside.   
     
     
         3 . The slide fastener as set forth in  claim 2 , wherein the pair of covering tapes are sewn to the folded portions through the pair of elements. 
     
     
         4 . The slide fastener as set forth in  claim 2 , wherein the pair of elements are sewn to the folded portions and the pair of covering tapes are bonded to the pair of elements. 
     
     
         5 . The slide fastener as set forth in  claim 2 , wherein the pair of covering tapes cover only upper surfaces of the pair of elements. 
     
     
         6 . The slide fastener as set forth in  claim 2 , wherein the pair of covering tapes cover the pair of elements such that the pair of elements are not exposed to the outside. 
     
     
         7 . A slide fastener that fastens separated portion of one or more outer material, the slide fastener comprising:
 a pair of fastener tapes including a pair of main body portions, and a pair of folded portions formed by folding each of opposite inner ends of the pair of main body portions in substantially U-shape;   a pair of elements attached to the pair of folded portions;   a slider that engages and disengages the pair of elements; and   a pair of covering tapes attached to the pair of elements,   wherein the slide fastener is attached to the outer material such that the covering tapes are exposed to the outside.   
     
     
         8 . The slide fastener as set forth in  claim 7 , wherein the pair of main body portions are sewn to the outer material at positions inner than outer ends of the pair of elements in a width direction of the slide fastener. 
     
     
         9 . The slide fastener as set forth in  claim 7 , wherein the pair of covering tapes are sewn to the folded portions through the pair of elements. 
     
     
         10 . The slide fastener as set forth in  claim 7 , wherein the pair of elements are sewn to the folded portions and the pair of covering tapes are bonded to the pair of elements. 
     
     
         11 . The slide fastener as set forth in  claim 7 , wherein the pair of covering tapes cover only upper surfaces of the pair of elements. 
     
     
         12 . The slide fastener as set forth in  claim 7 , wherein the pair of covering tapes cover the pair of elements such that the pair of elements are not exposed to the outside.
