Patent number: 9642451Abstract: Provided is a folding table for which a work of installing leg units on a tabletop is simplified, and squeaking and rattling are prevented even when the tabletop is used for a long period of time, so that the tabletop can be rotated smoothly. A protruding portion that protrudes in a horizontal direction is integrally formed on a bracket. By providing, on an upper portion of the leg units, a fitting hole into which the protruding portion fits and fitting the protruding portion into the fitting hole while crimping a distal end of the protruding portion in the horizontal direction, the bracket is connected to the leg units, and the tabletop is rotated using the protruding portion as a rotating shaft.Type: GrantFiled: October 26, 2011Date of Patent: May 9, 2017Assignee: OKAMURA CORPORATIONInventors: Naoyuki Okuda, Kenji Nakamura

Patent number: 8991932Abstract: A backrest mechanism for a chair includes a pair of left and right side rods, each having a folded portion in a laid-V shape in a side view at a portion for supporting a sitting person around his or her lumbar, and a back plate that connects opposing surfaces of the side rods. An upper portion of the back plate above the folded portions serves as a flexible portion that is elastically deformable in a backward direction and that has smaller rigidity than the left and right side rods, and a lower portion of the back plate below the flexible portion serves as an inflexible portion that has greater rigidity than the flexible portion.Type: GrantFiled: May 11, 2011Date of Patent: March 31, 2015Assignee: Okamura CorporationInventors: Naoyuki Okuda, Syouichi Izawa

Publication number: 20050098926Abstract: Raw materials are portioned in a plurality of molds, which are continuously moved and transferred to a heating area by a conveyer. The heating area is divided into a plurality of sub-areas, each of which has power source means and power feeding means. The raw materials are heated and molded by applying high frequency to the molds from the power feeding means. Even if the heating apparatus is large, it is possible to restrain or prevent concentration of high-frequency energy since the heating area is divided into sub-areas.Type: ApplicationFiled: May 7, 2002Publication date: May 12, 2005Inventors: Tomoya Tamura, Naoyuki Okuda, Yoshiyuki Otani, Tsutomu Kosaka, Yasuo Shinomiya, Toshitaka Haruta, Taizo Karasawa, Yoshio Akesaka, Masato Yanagitani, Tsuneo Nagata, Yasuji Yamamoto
