| 1995 | Invention patented by Takeshi Tsukamoto, Hiroshi Suzuki, and Akira Suzuki on December 11th, 1995. Abstract: Disclosed is an aseismic support structure having one end secured to a fixed floor and another end connected to a subject structure placed on a floating floor. The aseismic support structure includes a toggle bar, an attachment section and a mounting section. The toggle bar has a universal joint at each end and is adjustable in its length to have a predetermined length. The universal joints are rotatable around axes in the horizontal and vertical directions, respectively. The attachment section is connected to the toggle bar through one of the universal joints, and has at another end another universal joint comprising a vertical rotation section. The mounting section is connected to the attachment section through another universal joint, and secures the equipment. |
| 1996 | Invention patented by Junji Takayoshi, Katsushi Tanaka, and Takeshi Tsukamoto on August 15th, 1996. Abstract: An aseismic support structure which includes a fixed part which is attached to a stationary floor, an equipment connection part for holding part of the equipment and a moving part coupled to the fixed part and the equipment connection part and wherein the moving part is freely movable relative to the fixed part in any direction parallel with the stationary floor and the equipment connection part is freely rotatable about the moving part. The equipment can have a caster which is held by the equipment connection part. For a weak earthquake shock, a caster lock portion of the equipment connection part locks the caster of the equipment to prevent the movement of the equipment. For a stronger earthquake, resonance is prevented by the moving part moving in a direction parallel with the stationary floor, and for a ruinous earthquake the vibration of the moving part is absorbed by a shock absorbing member attached to the fixed part. |
