  • Seismic isolation mechanism
    Patent number: 9238919
    Abstract: A seismic isolation mechanism includes a seismic isolation apparatus which is installed at one end in a vertical direction on a superstructure and installed at another end 4 in the vertical direction on a floor serving as a foundation or a substructure to isolate the vibration of the superstructure with respect to the floor; a first attenuation damper which is connected to the superstructure and connected at another end a portion of the seismic isolation apparatus to attenuate the vibration of the superstructure with respect to the floor; and a second attenuation damper.
    Type: Grant
    Filed: April 16, 2015
    Date of Patent: January 19, 2016
    Assignee: Oiles Corporation

  • Seismic isolation mechanism
    Patent number: 9097309
    Abstract: A seismic isolation mechanism 1 includes a seismic isolation apparatus 6 which is installed at one end 2 in a vertical direction V on a superstructure 3 and installed at another end 4 in the vertical direction V on a floor 5 serving as a foundation or a substructure to isolate the vibration of the superstructure 3 with respect to the floor 5; an attenuation damper 10 which is connected at one end 7 in the horizontal direction H to the superstructure 3 and connected at another end 8 in the horizontal direction H to a portion 9 of the seismic isolation apparatus 6 between the one end 2 and the other end 4 thereof to attenuate the vibration of the superstructure 3 with respect to the floor 5 as it is extended and contracted in the horizontal direction H; and an attenuation damper 13 which is connected at one end 11 in the horizontal direction H to the floor 5 and connected at another end 12 in the horizontal direction H to the portion 9 of the seismic isolation apparatus 6 to attenuate the vibration of the super
