Patent number: 11384875Abstract: A pipe joint includes: a sealing member, having an annular shape, which is provided between the outer circumferential surface of a spigot and an inner circumferential surface of a socket; a pushing ring to push the sealing member into the socket, the pushing ring being fitted onto the spigot; and a separation preventive member configured to engage with the spigot protrusion part in a pipe-axial direction to prevent a separation of the spigot from the socket. The separation preventive member is provided between an inner circumferential surface of the pushing ring and the outer circumferential surface of the spigot. The sealing member is provided along an outer circumferential surface of the spigot protrusion part and includes a compression part. The compression part is compressed in a pipe-radial and is located, in the socket, upstream of the spigot protrusion part in an insertion direction in which the spigot is inserted.Type: GrantFiled: March 6, 2017Date of Patent: July 12, 2022Assignee: KUBOTA CORPORATIONInventors: Takahiro Ishihara, Shogo Kaneko, Kazuya Ito, Shota Yamada, Yuki Hieda

Patent number: 10520119Abstract: An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.Type: GrantFiled: December 18, 2015Date of Patent: December 31, 2019Assignee: Kubota CorporationInventors: Shozo Kishi, Takashi Yokomizo, Yoshinori Itani, Takaaki Kagawa, Kohei Ikeda, Shogo Kaneko

Patent number: 9659112Abstract: There are provided a pipeline structure and a computer readable recording medium having recorded thereon a program that supports the design of the pipeline structure. The pipeline structure includes two collars and a plurality of short pipes. The plurality of short pipes are connected by joint structures. Two collars are arranged to sandwich a zone where a fault displacement is expected to occur, and thereby, a ground displacement in the pipe axis direction is dealt with (absorbed). The plurality of short pipes are connected by the larger number of joints than the number of joints in the case of arranging a long pipe. By increasing the number of joints, it becomes easier to deal with (absorb) a ground displacement in the direction perpendicular to a pipe axis.Type: GrantFiled: December 9, 2014Date of Patent: May 23, 2017Assignee: KUBOTA CORPORATIONInventors: Shozo Kishi, Shogo Kaneko, Keita Oda
