Patent ID: 7707787

Claim:
A damping device comprising: a plurality of damping units constructed integrally, each of the damping units comprising a damping body horizontally movably resting against a base stand; an attenuator supported on the base stand for attenuation of moving force of the damping body; and a characteristic-frequency adjusting spring or springs through which said damping body is connected to said base stand for exertion of vertical expansion/contraction force, said attenuator and said spring or springs being mounted between the damping body and the base stand, the damping units being piled one above the other on a structure such that the corresponding damping bodies thereof may be moved perpendicular to each other and that the upper damping unit is piled on the lower damping unit on the structure, wherein movement of the upper and lower damping bodies is guided by linear guide mechanisms for the upper and lower damping bodies, respectively.
