| 20120246887 | THIN ZIPPER - A thin zipper includes two sets of coil zippers fastened to two base cloths. Each coil zipper includes a plurality of teeth and at least one core wire threading through the teeth and coupling the teeth in series. Each tooth includes a bracing section, two bent sections extended from two distal ends of the bracing section and a surface section. The bracing section has a bracing inner edge on an inner side to brace the core wire. Each bent section has a latch portion engaged with another latch portion of a different tooth. The surface section is located between the two bent sections and has a packing inner edge formed on an inner side to compress the core wire to generate deformation. The bracing inner edge and packing inner edge form an inner space between them at an interval smaller than the diameter of the core wire. | 10-04-2012 |
| 20130232736 | Slide Fastener - There is provided a slide fastener in which one of the fastener stringers is separated from a tape insertion path at one side of a body in the width direction when a lateral pulling force directed outward in the width direction of the fastener tapes is applied to a pair of fastener stringers. At least one opposing surfaces of an upper and lower flange at one side of the body in the width direction has a protrusion on the rear end portion thereof, and the opposing surfaces of the upper and lower flanges at one side of the body in the width direction respectively have straight portions which are parallel with each other except for the position at which the protrusion is formed. | 09-12-2013 |
| 20130340213 | DOUBLE-LAYER NYLON ZIPPER - A double-layer nylon zipper includes two zipper tapes each having two series of teeth respectively disposed at opposing top and bottom sides of the fabric strip thereof, and a zipper slider coupled between the interlocking series of teeth of the two zipper tapes and having opposing top guard frame wall and bottom guard frame wall, a division wall between the top and bottom guard frame walls, a nose located on the top guard frame wall and a pull tap coupled to the nose. The top guard frame wall and bottom guard frame wall have respective first ends kept in flush and respective second ends in different lengths so that an accommodation space is defined right below the second end of the top guard frame wall outside the second end of the bottom guard frame wall to facilitate smooth interlocking of the interlocking series of teeth. | 12-26-2013 |
