Patent ID: 7171792

Claim:
A truss comprising: a first upper longitudinal member with first and second ends and a second upper longitudinal member with first and second ends, wherein the first end of the first upper longitudinal member and the first end of the second upper longitudinal member are joined at an angle, forming a truss peak junction; a first tensioning member wherein one end of said first tensioning member is perpendicularly secured to the first upper longitudinal member at a first junction located between the first upper longitudinal member's first and second ends, from which the first tensioning member extends to a distal end; a second tensioning member wherein one end of said second tensioning member is perpendicularly secured to the second upper longitudinal member at a second junction located between the second upper longitudinal member's first and second ends, from which the second tensioning member extends to a distal end; a first vertical member with a top end rigidly secured to the first upper longitudinal member at a third junction located on said first upper longitudinal member between the second end of said first upper longitudinal member and the first junction; a second vertical member with a top end rigidly secured to the second upper longitudinal member at a fourth junction located on said second upper longitudinal member between the second end of said second upper longitudinal member and the second junction; a first cable with first and second ends, wherein said first cable's first end is secured to the first upper member near the truss peak junction, said first cable is routed to and from a point near the distal end of the first tensioning member, and said first cable's second end is secured to the first upper longitudinal member near the third junction, to carry tension applied between the first cable's first and second ends; a second cable with first and second ends, wherein said second cable's first end is secured to the second upper member near the truss peak junction, said second cable is routed to and from a point near the distal end of the second tensioning member, and said second cable's second end is secured to the second upper longitudinal member near the fourth junction, to carry tension applied between the second cable's first and second ends; and a third cable with first and second ends having its first and second ends secured so as to apply tension that opposes spreading of the locations of the third and fourth junctions.
