PCT No. PCT/JP82/00051 Sec. 371 Date Sep. 29, 1982 Sec. 102(e) Date Sep. 29, 1982 PCT Filed Feb. 24, 1982 PCT Pub. No. WO82/02930 PCT Pub. Date Sep. 2, 1982.A support device for supporting a supported structure above a supporting structure, in which a ball (2) is rotatably held at the top of a first component (A) disposed on the side of either one of the supporting structure and the supported structure, and a second component (B) is so supported that this ball can be in rolling contact with a concave surface (3) of the second component, which is disposed in contact with the side of the other of supported structure and the supporting structure. On the outer side of the first component (A), a support cylinder (11) is slidably fitted, and this support cylinder (11) and the second component (B) are hinge-coupled by a parallel-linkage mechanism. The support cylinder (11) is pulled toward one of the sides by a pulling mechanism, the ball (2) and the concave surface (3) of the second component being pressed into contact, and the centripetal force acting between the ball and the concave surface is utilized to stably hold the supported structure in a normal position on the supporting structure. This support device can be used as a support device of bodies of transportation facilities and architectural structures. |
