Patent ID: 8650811

Claim:
An apparatus comprising: a plurality of platforms, each having a corresponding first side and a corresponding second side opposite the corresponding first side; and a plurality of beams connected to corresponding second sides of the plurality of platforms at corresponding connection points, wherein the corresponding connection points are configured such that corresponding orientations of the plurality of platforms remain substantially unchanged in response to a load on the-plurality of platforms, wherein the corresponding connection points are configured to receive a plurality of loads applied at the plurality of connection points in response to the load on the plurality of platforms, and wherein at least a portion of the corresponding connection points is configured to move in response to the plurality of loads such that the corresponding orientations of the plurality of platforms remain substantially unchanged in response to the load; wherein the plurality of beams comprises a plurality of groups of beams forming a plurality of levels of hierarchy for the plurality of beams, wherein a lowest level of hierarchy in the plurality of levels of hierarchy for the plurality of beams is formed by a first group of beams in the plurality of groups of beams connected to a support structure and wherein a highest level of hierarchy in the plurality of levels of hierarchy for the plurality of beams is formed by a second group of beams in the plurality of groups of beams connected to the number of platforms.
