Patent number: 10322278Abstract: A clamping device is provided in which an other end portion is prevented from being excessively displaced in the transition from a clamped state to an unclamped state. A clamping device includes a one end portion having a locked part at a tip, an other end portion having a locking part capable of locking the locked part, a middle portion continuous with the one end portion and with the other end portion, and an insertion hole (H1, H2) allowing a flexible tube T to be inserted therethrough. An unclamped state is established when the locked part locked is unlocked by bending the other end portion such that the other end portion is displaced from the one end portion. The clamping device is configured to clamp the flexible tube T in a clamped state where a first projection and a second projection are positioned close to each other and to intercept a flow of a fluid at a clamped position.Type: GrantFiled: December 18, 2017Date of Patent: June 18, 2019Assignee: Nikkiso Company LimitedInventors: Ryo Kato, Shigeaki Funamura

Publication number: 20170326294Abstract: A clamping device capable of clamping a flexible tube in a good manner without fail and also capable of intercepting the flow of a fluid in the flexible tube more exactly. A clamping device includes a one end portion having a locked part at a tip, an other end portion having a locking part capable of locking the locked part, and insertion holes allowing a flexible tube to be inserted between a first projection and a second projection. In a clamped state, the first projection and the second projection are positioned close to each other, and the flexible tube is thus clamped so that the flow of a fluid is intercepted at the clamped position. The other end portion has interfering parts. When the one end portion is further pressed with the locked part being locked by the locking part, the interfering parts interfere with predetermined points and prevents further movement of the locked part.Type: ApplicationFiled: August 1, 2017Publication date: November 16, 2017Inventors: Ryo Kato, Shigeaki Funamura
