Abstract:
1. A flexure bearing spring capable of springing multiple bodies, the spring having a peripheral frame and a central axis perpendicular to the peripheral frame, the spring comprising: (a) a primary arm set comprising a plurality of primary spring arms separated from each other by openings, each primary arm extending inwardly from the peripheral frame along a non-radial primary path progressing inwardly toward the central axis and angularly about the central axis to a primary end connector; and (b) a secondary arm set comprising at least one secondary spring arm, each secondary arm extending along a non-radial secondary path progressing radially and angularly about the central axis to a secondary end connector, each secondary arm being interposed in an opening between the primary arms so that the arms of each set can independently pass through the openings between the arms of the other set.
