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

Publication number: 20160264030Abstract: A cover fastening clip includes a locking section that locks with an end member to be locked that is provided on the edge of a cover, and a hook that engages with a wire disposed in a groove of a cushion material. The hook is provided with an extended section that extends down from the locking section and a claw-shaped section, and the locking section is provided with a guide piece. The guide piece extends down along the extended section of the hook, bends at a midway bending section, and extends toward the distal end of the claw-shaped section. A wire insertion opening that has a prescribed gap and into which the wire is inserted is formed by the distal end of the guide piece reaching a location that faces the distal end of the claw-shaped section.Type: ApplicationFiled: November 1, 2013Publication date: September 15, 2016Applicant: YKK CorporationInventors: Shinsuke Saiga, Tetsuya Yoshino, Yoshitomo Iyoda

Publication number: 20160174719Abstract: A clip has an engagement portion including: a first arm with a first claw at the top end side; a second arm with a second claw at the top end side; and a bottom provided at the respective base end sides of the first arm and the second arm. Projections of the first claw and the second claw defines a left-right width of a mouth. A third claw projects into the retaining space at a position closer to the base end of the first arm, and a fourth claw is provided which projects into the retaining space at a position closer to the base end of the second arm. The third claw is narrower than the first claw in their widths along a front-back direction orthogonal to the depth direction of the retaining space extending from the mouth to the bottom and the left-right width direction of the mouth.Type: ApplicationFiled: August 27, 2013Publication date: June 23, 2016Inventors: Shinsuke Saiga, Tetsuya Yoshino, Yoshitomo Iyoda

Publication number: 20160167554Abstract: There is provided a cover material fastening clip for attaching a cover material to a cushion material. The clip is provided with a locking portion, a hook portion and a guide portion. The hook portion is provided with an extending portion that extends downward from the locking portion, a first hook piece a second hook portion. The guide portion is formed in the locking portion or the extending portion and is located above the first and second hook pieces. A space between a leading end portion of the first hook piece and the guide portion serves as a first insertion opening with a predetermined gap into which the wire is inserted. A space between a leading end portion of the second hook piece and the guide portion serves as a second insertion opening with a predetermined gap into which the wire is inserted.Type: ApplicationFiled: December 2, 2015Publication date: June 16, 2016Inventors: Ryuichi Murasaki, Genta Matsumura, Tomonari Yoshida, Yoshitomo Iyoda, Shinsuke Saiga

Publication number: 20160128435Abstract: There is provided a hook-and-loop fastener manufacturing method. Injection molding is performed to form a molded product in which a pillar group and a base plate having a surface from which the pillar group protrudes are integrated into a unified body. A tip part of the pillar group is cut to form a cut product in which a small pillar group shorter than the pillar group and the base plate are integrated into a unified body. A tip part of the small pillar group is melted to form pillar body portions which are non-melted portions and engaging portions which are melted portions and thicker than the pillar body portions from small pillars. The engaging portions are cooled to determine shapes of a plurality of engaging elements including the pillar body portions and the engaging portions.Type: ApplicationFiled: October 29, 2015Publication date: May 12, 2016Inventors: Tetsuya Fukuzawa, Yasuaki Funo, Yoshitomo Iyoda, Wanli Zhang

Patent number: 8403491Abstract: An optical combiner in which fewer parts are used comprises an optical component and a plastic body. The component comprises: a first filter reflecting first light having a first wavelength and being transparent to second light having a second wavelength and third light having a third wavelength; a second filter reflecting second light and being transparent to third light; and a base transparent to second light and third light. The first filter and the second filter are provided on opposed surfaces of the base. The plastic body has first, second, and third surfaces, and the first surface provides first, second, and third lenses. The component is provided in the plastic body such that light from the first lens is connected to a path to the second surface through the first filter and light from the second lens is connected to the path through the second filter. The third surface is a reflecting surface for connecting light from the third lens to the path.Type: GrantFiled: April 7, 2010Date of Patent: March 26, 2013Assignee: Sumitomo Electric Industries, Ltd.Inventors: Yoshitomo Iyoda, Akira Inoue, Tomomi Sano, Michiko Takushima, Takayuki Shimazu

Patent number: 8098435Abstract: An optical combiner in which the number of parts used is lessened is made of a resin. The optical component comprises a first surface, a diffraction grating, and a second surface. The first surface is a surface providing first, second, and third lenses. The diffraction grating diffracts to a common optical path leading to the second surface light of the first wavelength incident on the first lens, light of the second wavelength incident on the second lens, and light of the third wavelength incident on the third lens. The second surface emits light incident thereon through the common optical path. The optical path from the first surface to the diffraction grating and the common optical path are constituted of the resin.Type: GrantFiled: April 7, 2010Date of Patent: January 17, 2012Assignee: Sumitomo Electric Industries, Ltd.Inventors: Yoshitomo Iyoda, Akira Inoue, Tomomi Sano, Michiko Takushima, Takayuki Shimazu
