Patent number: 9549593Abstract: The slide fastener has a separable bottom end stop, and the separable bottom end stop has at least an insert pin and a box pin. The insert pin has an escape portion provided with an inclined surface or a curved surface along which the thickness dimension of the insert pin decreases in the direction of the tape width toward the side edge that faces the box pin, the escape portion being positioned in the front-end corner portion of a first-surface of the insert pin, the corner portion being positioned along the edge that faces the box pin. This allows the escape portion of the insert pin to function as an interference prevention means, efficiently prevent chain failure in an element row when the slide fastener is bent into a U-shape, and maintain stable engaging.Type: GrantFiled: March 30, 2011Date of Patent: January 24, 2017Assignee: YKK CorporationInventors: Masayoshi Kojima, Miyuki Ohgaku

Patent number: 9526302Abstract: There is provided a cover-material fastening clip for connecting a cover material and a cushion material. An engaging part engaged with the cover material. A hook is provided below the engaging part and is formed with: a claw-shaped part engaged with a wire provided in a groove of the cushion material; and a jig receiving part engaged with a jig for separating the hook from the wire. A position at which the jig receiving part is engaged with the jig is located at a side opposite to the engaging part relative to a position at which the hook is engaged with the wire. When the jig is engaged with the jig receiving part and is pulled up, the clip is rotated about the wire and the wire is separated from the claw-shaped part, so that the connection between the cover material and the cushion material is released.Type: GrantFiled: July 29, 2014Date of Patent: December 27, 2016Assignee: YKK CorporationInventors: Shinsuke Saiga, Yoshitomo Iyoda, Tetsuya Yoshino

Patent number: 9521884Abstract: In a fastener chain, at least some warps constituting a woven fastener tape are provided with a flame retardant phosphorus-copolymerized polyester fiber and wefts constituting the same fastener tape are provided with a synthetic fiber that is not phosphorus-copolymerized and that has a higher degree of tensile strength than the flame retardant polyester fiber. With this configuration, superior flame retardancy can be stably obtained and there is no variance in the flame retardancy of the fastener chains. In the fastener chain, the heat contraction of the warp is used to improve the chain horizontal pull force, and by increasing the frictional resistance between the warp and the weft, shifting of the weave pattern of the fastener tape can be prevented. Further, the fastener chain can be provided at a low cost because of the small amount of flame retardant polyester fiber used.Type: GrantFiled: September 29, 2010Date of Patent: December 20, 2016Assignee: YKK CorporationInventors: Shinji Matsuzawa, Takuya Shimizu, Yusuke Numata, Satoshi Kuno, Takayuki Hasegawa

Patent number: 9521883Abstract: There is provided a slide fastener. Each of a pair of fastener element rows is a coil-shaped fastener element row made of synthetic resin. Each of fastener elements includes an engaging head section, a first leg section and a second leg section. The first and second leg sections protrude from the engaging head section and extend parallel to each other. The first leg section comes in contact with the corresponding fastener tape and the second leg section does not come in contact with the corresponding fastener tape. The first leg section is colored in a color different from those of the fastener tapes and the second leg section. The color of the first leg section is visible through a gap between the pair of fastener tapes.Type: GrantFiled: May 28, 2012Date of Patent: December 20, 2016Assignee: YKK CorporationInventors: Satoshi Matsumoto, Chih Hung Lin

Patent number: 9510650Abstract: In a knitted fastener stringer, a fastener element is fixed by a fixing chain stitch yarn disposed on an element attaching portion of a fastener tape. This fixing chain stitch yarn has a first needle loop which is knitted into a ground structure and a second needle loop which fixes upper and lower leg portions of the fastner element. As a result, it is possible to achieve an improvement of productivity and a large reduction of a manufacturing cost by increasing a knitting speed and further to stably obtain flexibility and a soft texture in the knitted fastener stringer.Type: GrantFiled: July 19, 2011Date of Patent: December 6, 2016Assignee: YKK CorporationInventors: Norio Uozumi, Hidenobu Kato, Yoshito Ikeguchi

Patent number: 9492844Abstract: A multi-face part is provided on a half-finished product which eventually becomes a metal decorative button. The multi-face part includes a plurality of small sectional faces and ridges obtusely joining between two adjacent small sectional faces. An outside of the half-finished product including the multi-face part is plated. Then, the half-finished product is barrel-polished. Thereby, the plating on portions corresponding to the small sectional faces remains and the plating on portions corresponding to the ridges is removed, exposing the ground color of the half-finished product. Then, the multi-face part is partially compressed to form the metal decorative button having a compressed decorative surface. The compressed decorative surface is given a pattern composed of a plurality of small sectional parts corresponding to the small sectional faces with the plating left and boundaries corresponding to the ridges with the plating removed.Type: GrantFiled: June 8, 2010Date of Patent: November 15, 2016Assignee: YKK CorporationInventors: Kenji Hasegawa, Nobuhisa Ito

Patent number: 9480311Abstract: In a slide fastener, at least one stopping element including a resistance portion that increases sliding resistance by being brought into contact with an inner surface of a slider when the slider is sliding is locally disposed locally on an element row of a fastener stringer. Accordingly, the slider can be stopped at any position where the stopping element is disposed arbitrarily on the element row and an immobilized state of the slider can be maintained. By operating the slider with a force greater than the sliding resistance to the stopping element, the slider can be made to ride over the resistance portion of the stopping element and to slide along the element row.Type: GrantFiled: March 24, 2011Date of Patent: November 1, 2016Assignee: YKK CorporationInventors: Go Takani, Masayoshi Kojima

Patent number: 9462853Abstract: There is provided a slider for a slide fastener. A lock member is swingably supported by a pillar portion which is erected on an upper surface of a body. A cover member covers the pillar portion and the lock member from above. The lock member includes a body portion which is disposed on the upper surface of the body and a claw portion which protrudes from the body portion and enters an element guide path of the body. One side surface of the claw portion is formed with an inclined surface which causes the claw portion to be gradually tapered toward a front end of the claw portion. The other side surface of the claw portion is formed with a stepped portion which causes a plate thickness of the claw portion to be smaller than a plate thickness of the body portion.Type: GrantFiled: April 27, 2011Date of Patent: October 11, 2016Assignee: YKK CorporationInventors: Yoshikazu Hamada, Keiichi Keyaki
