Patent number: 11559116Abstract: A slider includes a slider body part that includes an upper wing plate and a lower wing plate, a stop tab body, a tab elastic member that biases the stop tab body, a base part integrally formed with the upper wing plate, and an operation cover part rotatably attached to the base part. The operation cover part includes a pressing projecting part that projects from an inner surface of a top plate part, and the pressing projecting part has a configuration in which by rotating the operation cover part, a locked state and an unlocked state can be switched therebetween. Accordingly, since a stop mechanism by the rotation of the operation cover part can be provided in the slider with a relatively simple configuration, the manufacturing cost can be reduced and the productivity can be improved.Type: GrantFiled: December 20, 2018Date of Patent: January 24, 2023Assignee: YKK CorporationInventors: Yohei Miyazaki, Koji Yamagishi, Yoshikazu Hamada

Patent number: 10869525Abstract: A slider for a slide fastener includes a body, a pull-tab, a control claw, and a cover. The control claw is placed on a shaft portion between a front attachment column and a rear attachment column. A protrusion length of a claw portion that enters an element path from a claw hole changes depending on an up-down position of the shaft portion so as to control movement of the body. The cover is attached to the front attachment column and the rear attachment column so as to be swingable in an up-down direction. The upper plate portion pushes the control claw downward due to a restoring force of a plate spring portion extending from a front end of the upper plate portion along a front surface of the front attachment column. The body, the pull-tab, the control claw, and the cover are separate components.Type: GrantFiled: July 19, 2017Date of Patent: December 22, 2020Assignee: YKK CorporationInventors: Yohei Miyazaki, Yoshikazu Hamada

Patent number: 9381744Abstract: An image forming apparatus includes a recovery device to recover a droplet discharge head. The recovery device includes a slider and a suction unit. The slider contacts a nozzle formation face of the droplet discharge head and moves along a nozzle row of the droplet discharge head. The slider includes two portions spaced away from each other in a direction traversing a movement direction of the slider. The suction unit opposes nozzles of the droplet discharge head and moves without contacting the nozzle formation face. The suction unit is disposed at a position between the two portions of the slider and downstream from the two portions of the slider in the movement direction of the slider. The slider collects droplets adhered to an area outside the nozzle row of the nozzle formation face.Type: GrantFiled: May 21, 2015Date of Patent: July 5, 2016Assignee: RICOH COMPANY, LTD.Inventor: Yohei Miyazaki

Patent number: 9271548Abstract: Provided is a slider for slide fastener. A pull-tab has a cam portion, and when the pull-tab is rotated from a laid-down state where the pull-tab is laid down toward one side of a slider main body to an erected state, the pull-tab is urged with using the cam portion in a direction in which the pull-tab reruns to the laid-down state by an elastic force of a spring part. The slider has a restraining part configured to prevent the pull-tab from rotating further from the erected state and prevent the pull-tab from being laid down toward the other side of the slider main body.Type: GrantFiled: June 17, 2011Date of Patent: March 1, 2016Assignee: YKK CorporationInventors: Keiichi Keyaki, Yohei Miyazaki

Patent number: 9072347Abstract: A slider for a slide fastener includes a stopper mechanism formed for “forward use,” in which the surface where coiled fastener elements are attached on a fastener tape is the front surface, can be used for “reverse use,” in which the surface where the coiled fastener elements are attached on the fastener tape is the back surface. The inner surface of the lower blade of the slider body of a slider has a protrusion that extends in the forward-reverse direction from a guiding bar towards a posterior opening. The protrusion has a first horizontal upper surface on the guide bar end of the protrusion that is highest and a second upper surface on the posterior opening end that is lower than the first upper surface.Type: GrantFiled: September 2, 2011Date of Patent: July 7, 2015Assignee: YKK CorporationInventors: Yoshikazu Hamada, Keiichi Keyaki, Yohei Miyazaki

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
