Abstract:
A motion-magnifying seismic shock-absorbing construction for placement in the polygonal frame of a structure comprising a first link having a shock-absorbing member therein, a first end on said first link for connection to a first area on said frame, a second end on said first link, a second link having a first end for connection to a second area on said frame remote from said first area, a second end on said second link, a third link in the form of a lever for connection to a third area on said frame remote from said first and second areas, said third link having a central portion, a pivotal connection on said frame mounting said central portion, first and second end portions on said third link extending outwardly from opposite sides of said pivotal connection, said second end of said first link being pivotally connected to said first end portion of said third link remote from said pivotal connection, and said second end of said second link being pivotally connected to said second end portion of said third link remote from said pivotal connection, said first and second end portions of said third link being dimensioned such that motion of said second link transmitted to said first link through said third link is always magnified by the pivotal action of said third link regardless of the direction of the force applied to said first link.
