Patent number: 8925161Abstract: A readily burstable slide fastener for an inflatable device, such as a lifejacket, includes a first stringer, a second stringer and a slider slidably mounted on the second stringer. At a weakened region along the slide fastener coupling elements are omitted from each of the stringers so that when a bursting force is applied to this region the coupling elements adjacent thereto are disengaged. Coupling elements are omitted from the top of the first stringer so that when the slider is at the top of the coupling elements of the second stringer, the first stringer can disengage from the slider. When the slide fastener is fitted to an inflatable lifejacket, the stringers are separated completely when the lifejacket is inflated.Type: GrantFiled: September 23, 2011Date of Patent: January 6, 2015Inventors: Shigeyoshi Takasawa, Shunji Akashi, Mark Davies

Patent number: 8844101Abstract: A reverse opening slide fastener is provided with a pair of first and second separable connection members which are firmly fixed to first and second fastener stringers, and a pair of first and second sliders. A connection and separation operation can be carried out by inserting and removing the second separable connection member into and from the first and second sliders. The second separable connection member has an inserting and removing region which can be inserted into and removed from the first and second sliders via a gap between upper and lower flanges of the first and second sliders. Further, a positioning structure which decides a relative position between the first separable connection member and the second separable connection member is arranged, whereby it is possible to improve an operability of the connection and separation operation.Type: GrantFiled: December 25, 2009Date of Patent: September 30, 2014Assignee: YKK CorporationInventors: Jiro Nozaki, Shunji Akashi

Publication number: 20110041296Abstract: The present invention provides a slide fastener in which a broken part of a coupling element is not separated easily at the time of a forced cleavage when an airbag is expanded and having an excellent appearance. In the slide fastener (110) in which coupling elements (12, 113) each having a first leg portion and a second leg portion (72; 73) which are forked and extended from a coupling head (70) are sewed to a fastener tape (16, 17) thereof, a V-shaped cutout portion is formed at a single position in the range from a sewing line (84) on a first sewing portion (74) of the first leg portion (72) up to a sewing line (85) on a second sewing portion (75) via a coupling head (70) so as to form a vulnerable portion (80) whose breaking resistance is weakened. Consequently, even if an excessive lateral pulling force is applied to the slide fastener (110), so that the coupling element (12) is broken at the vulnerable portion (80), a broken part of the coupling element (12) is held on the fastener tape (16, 17).Type: ApplicationFiled: December 11, 2008Publication date: February 24, 2011Applicant: YKK CorporationInventors: Kenji Dono, Shunji Akashi, Hiroshi Ishisaka, Naoyuki Himi

Patent number: 7337508Abstract: In a zip fastener the elements (10) on one tape have a head which engages a shoulder (20) of an opposed element to limit out of plane movement. A small number of elements (30) have a head (38) which bears on a shoulder 46 when twisted in one direction but passes the shoulder (46) when twisted in the opposite direction to allow partial separation of the elements to create a point of weakness. The coupled elements can be peeled apart when sufficient pressure is applied to one side of the tape at the point of weakness, but the elements resist twisting when pressure is applied to the opposite side.Type: GrantFiled: June 24, 2005Date of Patent: March 4, 2008Assignee: YKK CorporationInventors: Shigeyoshi Takasawa, Mark Davies, Shunji Akashi
