Publication number: 20230013090Abstract: An element member (10) according to the invention includes a fixing member (11) and a plurality of fastener elements (20, 20a, 20b) attached to the fixing member (11), characterized in that the fastener element (20, 20a, 20b) includes an element fixing portion (22) fixed to the fixing member (11), a coupling portion (23) extending from the element fixing portion (22) in a width direction, and a fin portion (24, 25, 26) extending from the element fixing portion (22) to a side opposite to the coupling portion (23). The fastener element (20, 20a, 20b) is fixed to the fixing member (11) only at the element fixing portion (22). As a result, in a slide fastener-attached product (1) manufactured by using the element member (10), the orientation of the fastener element (20, 20a, 20b) is prevented from being tilted with respect to a fastener attached member (2) and smooth sliding operation of a slider (40) can be ensured.Type: ApplicationFiled: July 4, 2019Publication date: January 19, 2023Inventors: Yu Chen Tung, Yoshiyuki Sho, Yuko Fukuda

Patent number: 11425972Abstract: Stop member includes: a first member including a first insert to be inserted into a slider via a rear mouth of the slider, and a first base positioned rearward of the first insert; and a second member including a second insert to be inserted into the slider via a slit extending between the rear mouth and a front mouth of the slider, and a second base to be overlaid onto the first base. The first and second bases are configured to effect magnetic attraction and/or repulsion between the first and second bases when the first and second bases are overlaid. The second base rotates relative to the first base in accordance with the magnetic attraction and/or repulsion to allow the second insert to pivot toward the slit.Type: GrantFiled: March 12, 2018Date of Patent: August 30, 2022Assignee: YKK CORPORATIONInventors: Tomoyuki Ekko, Yu Chen Tung, Jiro Nozaki

Patent number: 11363859Abstract: Fastener element of slide fastener has an intermediate portion including bent or curved portion between a terminal portion and a base portion. The intermediate portion has an engaging protrusion and an engaged recess which are respectively protruded and recessed on an axis that matches a movement direction of the slider. In an orthogonal direction orthogonal to the axis, a first distance between the axis and the terminal surface of the terminal portion is less than a second distance between the axis and the base end surface of the base portion.Type: GrantFiled: May 7, 2018Date of Patent: June 21, 2022Assignee: YKK CORPORATIONInventors: Yu Chen Tung, Shigeyoshi Takazawa, Yoshinori Kojima

Patent number: 11206901Abstract: A slide fastener-attached product has a first element member in which an insert pin portion is attached to a fixing member, a second element member in which a box portion is attached to a fixing member and fastener attached members having a pair of element attaching edge portions in a position facing to each other. The first element member and the second element member have an element holding portion and a component holding portion in which the insert pin portion or the box portion is attached with respect to the length direction of the fixing member, and at least the component holding portion is fixed to the element attaching edge portion of the fastener attached member with a component sewn portion which is formed of sewing threads and pierces the fastener attached member. The product provides weight saving, improved softness, and an easily separable rear end stop.Type: GrantFiled: October 6, 2017Date of Patent: December 28, 2021Assignee: YKK CorporationInventors: Yu Chen Tung, Yoshiyuki Sho

Patent number: 11202487Abstract: A first stop member includes a first base and a first insert that is positioned between the first base and a first fastener element and is inserted into the slider via a rear mouth of a slider. A second stop member includes a second base and a second insert that is positioned between the second base and a second fastener element and is inserted into the slider via a second slit of the slider. The second insert moves toward the second slit of the slider in accordance with at least one or respective rotations of the first and second bases. A rotational axis with respect to the at least one or respective rotations of the first and second bases is positioned between the first tape region and the second tape region.Type: GrantFiled: September 26, 2017Date of Patent: December 21, 2021Assignee: YKK CORPORATIONInventors: Yu Chen Tung, Jiro Nozaki, Shigeyoshi Takazawa, Yoshinori Kojima, Shigeki Annaka
