Octohedral frame and tripod for rotating equipment

An apparatus for rotatively supporting equipment, comprising:

• a first elongated compression member having a first end coupled to a node comprising a rotatable bearing, said first elongated compression member having a second end;
• a second elongated compression member having a first end coupled to said node comprising a rotatable bearing, said second elongated compression member having a second end;
• a third elongated compression member having a first end coupled to said node comprising a rotatable bearing, said third elongated compression member having a second end;
• a rotatable fourth elongated compression member having a first end coupled to said rotatable bearing, said rotatable fourth elongated compression member having a second end, said rotatable fourth elongated compression member being supported near its second end by passing through an annular member comprising a second rotatable bearing;
• a first tension member coupled between the second end of said first elongated compression member and the second end of said second elongated compression member;
• a second tension member coupled between the second end of said second elongated compression member and the second end of said third elongated compression member;
• a third tension member coupled between the second end of said third elongated compression member and the second end of said first elongated compression member;
• a fourth tension member coupled between the second end of said first elongated compression member and a first projection on said annular member;
• a fifth tension member coupled between the second end of said first elongated compression member and a second projection on said annular member;
• a sixth tension member coupled between the second end of said second elongated compression member and the first projection on said annular member;
• a seventh tension member coupled between the second end of said second elongated compression member and a third projection on said annular member;
• an eighth tension member coupled between the second end of said third elongated compression member and the third projection on said annular member;
• a ninth tension member coupled between the second end of said third elongated compression member and the second projection on said annular member;
• the first tension member, the second tension member, and the third tension member forming a triangular shaped base;
• the fourth tension member, the fifth tension member, the sixth tension member, the seventh tension member, the eighth tension member, and the ninth tension member forming a hexapod, with the three projections of the annular member forming the upper triangle of the hexapod, and the first tension member, the second tension member, and the third tension member forming the base triangle of the hexapod;
• and,
• wherein said tension members and said compression members cooperating to react against each other internally in order to form a substantially rigid tension-compression structure, said structure being supported at said base triangle of the hexapod.
