Patent number: 9879809Abstract: A coupling which can enhance safety will be provided, when the coupling, a hose, and the like are exposed to high pressure for some reasons or other while in use, by leaking the high pressure fluid to the outside to open a sealing portion of the coupling at a stage where the coupling condition between the couplings is maintained, and decreases the pressure. Further, the coupling can warn the operator or the like of the abnormality by ejecting a fluid from a leak path or a fluid ejection port.Type: GrantFiled: January 27, 2017Date of Patent: January 30, 2018Assignee: SAKURA RUBBER CO., LTD.Inventor: Akira Horimoto

Patent number: 7798537Abstract: A coupling apparatus includes projections projecting axially from circumferential positions on a distal part of an annular body, each projection having an engaging hook projecting in one circumferential direction at an end part thereof. The body and the projections are formed independently of each other, and the apparatus includes a fixing structure for fixing the projections to the positions on the distal part. After inner peripheries of the projections are placed on the outer periphery of the distal part adjacent to an outward overhang, the fixing structure is detachably fixed on the outer periphery in a side of the projections axially opposing to the overhang and has an inward tapering surface fitted on an outward tapering surface of each projection to fix the projections at the predetermined positions on the outer periphery, and includes a cutout exposing the outward tapering surface of at least one projection.Type: GrantFiled: March 26, 2009Date of Patent: September 21, 2010Assignee: Sakura Rubber Co., Ltd.Inventors: Tetsuya Nakamura, Akira Horimoto, Kazuyuki Tamada
