Title:
SEISMIC ISOLATOR
Document Type and Number:
Japanese Patent JP2016080045
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a seismic isolator capable of preventing resonance at a natural frequency of an elastic member trying back to its origin, assuring a movable region to make a small-size of it and capable of mounting loaded items in a stable manner.SOLUTION: A seismic device comprises a base plate member 11; a load mounting plate member 12 arranged on the base plate member 11 on which a load item is mounted; a rolling member 14 arranged between the base plate member 11 and the load mounting plate member 12 to enable a relative motion to be carried out; and a plurality of elastic members 13 connected between the base plate member 11 and the load mounting plate member 12. The elastic members 13 perform a connecting operation between a first connecting point 16 at a side of a center point O of the base plate member 11 and a second connecting point 17 at a side of an outer periphery of the load mounting plate member 12 while a radiation direction A of the center point O of the base plate member 11 and a linear line direction B connecting the first connecting point 16 with the second connecting point 17 are being displaced, and the rolling member 14 is concentrically arranged on the second connecting point 17 or arranged at more outside than the second connecting point 17.SELECTED DRAWING: Figure 2
