Abstract
Abstract A laminated rubber support assembly which earthquake-proofs buildings. It comprises a plurality of rigid plates arranged to alternate with rubber-like elastic plates and adapted to support a heavy object in such a manner as to allow the object to swing horizontally. This laminated rubber support assembly is characterized in that at least the peripheral region of each rubber-like elastic plate interposed between rigid plates is not bonded to the rigid plates.
