US Patent:

7223187, May 29, 2007

Filed:

Apr 25, 2006

Appl. No.:

11/380172

Inventors:

Rafael P. Bouffard - La Mesa CA, US
Barton G. Dunlevy - La Mesa CA, US

International Classification:

A63B 61/02

US Classification:

473492, 473478

Abstract:

A frameless portable suspension system includes 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, and 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.
