Patent number: 8991017Abstract: There is provided a slider for a slide fastener. A cover member is attached to a body in a cantilever manner to cover a pillar portion and a lock member. An opening/closing member slidably formed between the cover member and the body is configured to open and close an insertion gap. The cover member has a first surface which is formed on the rear end portion of the cover member in substantially parallel to the body, and a second surface extending rearward and upward at a predetermined angle from a rear end portion of the first surface. The opening/closing member has a third surface which overlaps with the first surface in an upward and downward direction and is formed in substantially parallel to the first surface, and a fourth surface extending rearward and downward at a predetermined angle from a rear end portion of the third surface.Type: GrantFiled: April 15, 2011Date of Patent: March 31, 2015Assignee: YKK CorporationInventors: Yoshikazu Hamada, Keiichi Keyaki

Patent number: 8966720Abstract: A slider of the invention has a slider body and a tab, and first and second tab attachment posts of the slider body rotatably retain an attachment shaft portion of the tab. Further, a cover body covering at least the first and second tab attachment posts is fixed to an upper blade of the slider body. In accordance with this, since the slider has a good touch feeling and an improved outer appearance, it is possible to construct a slide fastener which is excellent in quality. Further, in the case that the slider has a stop mechanism, the stop mechanism can be protected by the cover body, and it is accordingly possible to prevent a trouble in the stop mechanism.Type: GrantFiled: December 24, 2010Date of Patent: March 3, 2015Assignee: YKK CorporationInventors: Yohei Miyazaki, Keiichi Keyaki

Patent number: 8959727Abstract: Provided is a slide fastener with a separable bottom end stop having both an automatic stopper and the separable bottom end stop, of which structural components can be used for both left- and right-insertions. In the slide fastener, a stop pawl for the automatic stopper protruding into an element guide passage via a pawl hole is configured to be movable in the lateral direction to an insert pin side and a box pin side. Accordingly, when the insert pin is inserted into the element guide passage through a shoulder opening of a top slider to re-couple separated fastener stringers, the stop pawl can be retreated by the insert pin as being pushed. Accordingly, the insert pin can be smoothly inserted deeply to the top slider with small resistance force. Further, structural components of the slide fastener with the separable bottom end stop can be used for both left- and right-insertions.Type: GrantFiled: December 26, 2008Date of Patent: February 24, 2015Assignee: YKK CorporationInventors: Keiichi Keyaki, Yuichi Iwase

Publication number: 20140331460Abstract: A slider provided with a stopping mechanism has a press molded slider body and a stopping pawl body. The stopping pawl body has a main body, a pawl portion extending from one end side of the main body, an extending portion extending from the other end side of the main body, and a projecting portion projecting from a tip portion of the extending portion, and the extending portion has a rotation support part of the stopping pawl body. A contact surface with which the rotation support part of the upper blade is in contact is formed into a flat surface. According to this constitution, a defect and failure of the stopping mechanism hardly occur in the slider, so that the stopping mechanism can be stably operated for a long period of time.Type: ApplicationFiled: December 27, 2011Publication date: November 13, 2014Applicant: YKK CorporationInventors: Koji Yamagishi, Keiichi Keyaki

Patent number: 8806725Abstract: A slide fastener according to the invention includes a left-and-right pair of first and second fastener stringers, a box pin provided on the first fastener stringer, an insert pin provided on the second fastener stringer, and a pair of first and second sliders. The box pin has a box pin body, a stopper portion, and a ridge portion formed on the box pin body. Further, a chamfered portion is formed on an inner surface of at least one of the upper and lower wing plates of the first slider. The ridge portion is arranged at a position in close contact with the chamfered portion of the first slider when the first slider is stopped at the stopper portion. With this arrangement, it becomes possible to cause the user to be accustomed to securely slide the first slider to the normal insert-pin inserting position.Type: GrantFiled: July 29, 2009Date of Patent: August 19, 2014Assignee: YKK CorporationInventors: Keiichi Keyaki, Takanori Ozawa

Patent number: 8782857Abstract: A slider with a stop mechanism includes a slider body having first and second post positions on an upper blade, a pull tab, and a bent leaf spring member. The leaf spring member includes first and second restraining portions which abut against the first and second post positions, respectively, to restrain upward movement. The first and second restraining portions are respectively disposed at positions to be spaced apart from the first and second post positions when the inclined angle ? of the pull tab is 0°. The first restraining portion is disposed in a relation to abut against the first portion and thus restrain the upward movement, when the inclined angle ? is in a range of 0°<?<180° or when the axis of the pull tab is spaced apart from the upper blade.Type: GrantFiled: September 10, 2010Date of Patent: July 22, 2014Assignee: YKK CorporationInventors: Keiichi Keyaki, Koji Yamagishi

Patent number: 8782858Abstract: A slider has an upper blade of a slider body having an insert groove of a locking pawl, a temporary engagement portion for which temporary engages and fixes the locking pawl, and a claw hole. The temporary engagement portion is adapted so that, with the locking pawl fixed in position, the position in height of the upper end of the temporary engagement portion is the same as or lower than that of the upper surface of the upper blade. This prevents the temporary engagement portion from being pressed and crushed when the temporary engagement portion is in contact with the tab and so on. As a result, an automatic stop mechanism of the slider can stably function.Type: GrantFiled: September 9, 2013Date of Patent: July 22, 2014Assignee: YKK CorporationInventors: Keiichi Keyaki, Koji Yamagishi, Takanori Ozawa
