Abstract:
1. A frameless portable suspension system, comprising: a tensional two-dimensional material having a frameless perimeter, opposite upper corners, and a bottom secured to ground, the tensional two-dimensional material located in a vertical plane perpendicular to the ground; a pair of adjustable spring mechanisms coupled to the upper corners and providing the upper corners in tension in an upward vertical direction and a outward horizontal direction, the adjustable spring mechanisms disposed rearward of the tensional two-dimensional material and including lower ends adjacent the ground that are freely pivotal relative to the ground, the lower ends forming vertices of angles defined by the adjustable spring mechanisms and the ground, and the angles freely changeable with free pivotal movement of the lower ends of the adjustable spring mechanisms; wherein the tension in the tensional two-dimensional material is adjustable with the adjustable spring mechanisms while the tensional two-dimensional material is under tension and the tensional two-dimensional material is positionable in a vertical plane perpendicular to the ground upon adjustment of the tension in the tensional two-dimensional material with the adjustable spring mechanism.
