ABSTRACT:
An apparatus for supporting a platform (84) relative to a base (82), has first, second, and third flexible shaft couplings (80). Each flexible shaft coupling (80) is mechanically coupled between the platform (84) and the base (82). Each flexible shaft coupling (80) has a rigid intermediate member (12) and a platform coupling (104) with a plurality of folded sheet flexures (20). Each folded sheet flexure (20) is coupled to the rigid intermediate member (12) on one side of a fold (36) and coupled to the platform (84) on the opposite side of the fold (36). Each flexible shaft coupling (80) also has a base coupling (102) with a plurality of folded sheet flexures (20) wherein each folded sheet flexure (20) is coupled to the rigid intermediate member (12) on one side of a fold (36) and coupled to the base (82) on the opposite side of the fold (36).
