Abstract
A portable exercise system has a foldable perimeter frame comprising at least two elongated frame members that are joined by hinges. The hinges are joined to ends of the frame members, which ends are generally tubular. Each hinge has a cap-like body having an interior surface that defines a cavity configured to nestingly receive one of the ends of the frame members. A deformable plug is located within the central cavity of the one of the ends. A tightening mechanism is operated to expand the plug radially and thereby cause the end to expand radially such the generally tubular outer surface of the end frictionally engages the interior surface of the a cap-like body.
