Isolation Platform

An isolation platform for a structure to be supported comprising:

• an upper plate upon which the structure to be supported is placed, said upper plate having a plurality of downward-facing, conical, rigid bearing surfaces;
• a lower plate secured to a foundation, said foundation supporting the isolation platform and the structure to be supported, said lower plate having a plurality of upward-facing, conical, rigid bearing surfaces disposed opposite said downward-facing, conical, rigid bearing surfaces, said downward and upward bearing surfaces defining a plurality of bearing cavities between said upper and lower plates;
• a plurality of rigid spherical balls interposed between said downward and upward bearing surfaces;
• said downward and upward bearing surfaces comprising central apices having the same curvature as that of said spherical balls such that a restoring force is substantially constant, and having recess perimeters having the same curvature as that of said spherical balls, which connects said central apices and recess perimeters with continuous slope, wherein the curvature of said spherical balls and downward and upward bearing surfaces are further configured such that as said spherical balls and upper and lower plates displace laterally relative to one another, vertical displacement of said upper and lower plates is near zero;
• and
• a retention mechanism for securing said lower plate and said upper plate together.
