Publication number: 20230068548Abstract: Legs of a pair of legs are provided with core-thread-pressing surfaces that slant gradually to approach one another as being away from the stopping surfaces. Each core-thread-pressing surface extends from the stopping surface to the base end of the leg. A thickness of each leg in a thickness direction of the fastener tape gradually increases from the free end toward the base end of the leg in accordance with at least the slanting of the core-thread-pressing surface.Type: ApplicationFiled: October 10, 2019Publication date: March 2, 2023Inventors: Chikako Hiromi, Futoshi Kozato, Shigeru Tsuchida

Patent number: 9101182Abstract: 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.Type: GrantFiled: April 28, 2010Date of Patent: August 11, 2015Assignee: YKK CorporationInventors: Futoshi Kozato, Yusuke Meiwa, Hirofumi Tanikoshi

Publication number: 20110010899Abstract: Metallic one-side teeth that attain preventing of colliding contact at interlock, enhancing of rigidity against moment by horizontal pull force and construction of simple structure; and a two-way slide fastener utilizing the metallic one-side teeth. An upper inclined plane (8) declining toward the side of interlock dent portion (5) is provided between the opening edge (5a) of the interlock dent portion (5) and the apical edge (7) of an interlock head portion (3). By virtue of the upper inclined plane (8), at insertion in the interlock dent portion (5), there can be prevented any insertion of an interlock convex portion (4) as an interlock counterpart-side while making colliding contact with the interlock head portion (3). Accordingly, the sliding movement of slider for opening/closing of a two-way slide fastener can be smoothed.Type: ApplicationFiled: April 14, 2008Publication date: January 20, 2011Applicant: YKK CorporationInventors: Futoshi Kozato, Hayato Ishii
