20130007993 | Metal Double-Sided Tooth and Slide Fastener - Provided are a metal double-sided tooth that prevents a flow protruding portion from protruding from the boundary between a coupling concave portion and a body, and a slide fastener using the metal double-sided tooth. The inner side of a coupling concave portion is formed in a substantially bowl shape and a concave portion is formed throughout the boundary between the coupling concave portion and a body and a front side and a rear side of the body. Further, when the metal double-sided tooth is attached to a fastener tape, it is possible to prevent a flow protruding portion generated by caulking a pair of legs from protruding outward from the coupling concave portion or the front side and the rear side of the body until sliding friction is generated in a slider. | 01-10-2013 |
20140150216 | Stop for a Slide Fastener, and a Method for the Manufacture Thereof - There is provided a stop for a slide fastener. A top plate and a bottom plate are linked with one another at a transversely intermediate position by an integral connecting post. The lower side of the top plate is substantially flat. The bottom plate slopes away from the connecting post to form two leg members provided with a respective end flange pointing towards the top plate, the leg members being adapted to cooperate in use with the top plate to retain fastener tapes therebetween. | 06-05-2014 |
