Patent number: 6336296Abstract: A floor system includes a plurality of panels placed on a base floor. A space is formed between the panels and the base floor for laying cables. A plurality of sliding plates are arranged on the base floor. A plurality of supports are provided and each support of the plurality of supports is arranged on each of the sliding plates so as to freely slide. The plurality of panels are supported by the plurality of supports by being fixed on a pedestal of the each support of the plurality of supports. The plurality of panels are hence connected to each other to form a single floor surface. The dynamic coefficient of friction between the bottom of the supports and the sliding plates is selected to be a value within a range of 0.09 to 0.25.Type: GrantFiled: December 28, 1999Date of Patent: January 8, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Yutaka Ishibashi, Shigeru Fujimoto, Isako Tsushima, Yoshio Kojima, Junko Oikawa

Patent number: 5386670Abstract: A floor panel having a rectangular floor base integrally with a convex prop in each corner portion and a concave portion on the upper surface of each prop. There is a height adjusting screw with a plate embedded in the concave portion of each prop, variably for adjusting the height of the support position in a predetermined range between a position lower than the upper surface of the prop and a position higher than the upper surface of the prop. A floor panel is supported by each prop of the floor base and has through holes for accessing the height adjusting screw for adjusting the support height at each corner according to the prop. In the method of manufacturing the floor base, a convex portion, which integrally projects to the upper surface side on four corners of a skin, is formed, a concave portion is formed on the lower surface of said convex portion, concrete is packed in the concave portion, thereby forming which is integral to said skin.Type: GrantFiled: November 29, 1991Date of Patent: February 7, 1995Assignee: Kabushiki Kaisha ToshibaInventors: Fumio Takeda, Yoshio Kojima, Yutaka Ishibashi, Isako Tsushima, Kenji Sugimoto, Hideo Tanaka, Hidetoshi Takahashi, Fumio Sumiyoshi

Patent number: 5245805Abstract: This invention relates to an interior panel unit having a structure in which a plurality of rectangular floor base members to be installed on a foundation floor of a room are connected to each other by base joint members. A plurality of fundamental support members having the same height and a plurality of connecting support members having the same height as that of the fundamental support members are located on each floor base member. Each floor panel member supported by the fundamental support members and the connecting support members is arranged to assure a predetermined space with the corresponding floor base member. Cables and various types of equipment which constitute an office-automation system are mounted in the space defined by the floor panel member and the floor base member. The space defined by the floor panel member and the floor base member is partitioned by vertical and horizontal separator members. The cables and various types of equipment are appropriately arranged in the partitioned space.Type: GrantFiled: October 11, 1991Date of Patent: September 21, 1993Assignee: Kabushiki Kaisha ToshibaInventors: Fumio Takeda, Yoshio Kojima, Tsuneo Kaneko, Yutaka Ishibashi, Naoto Sasaki, Isako Tsushima
