Aseismatic support platform

Abstract

The present invention relates to an aseismatic support unit, and more particularly to an aseismatic support unit capable of being easily and fitly in-situ assembled to become an aseismatic system. The aseismatic support unit is mounted between a base and a loaded article, comprising a lower support member, an upper support member and a plurality of aseismatic units mounted therebetween. Each of the aseismatic units includes a lower carry member having an upward carry surface, an upper carry member having a downward carry surface and a support roller mounted therebetween. When an earthquake happens, shakes are transmitted from the base. Then, the aseismatic support unit of the present invention diminishes the extent of the shakes of the load article placed over the upper support member and thus prevent the loaded article from overturn and damage as a result of the earthquake.
