Abstract:
A plurality of similarly configured coupling component assemblies is provided. Each assembly includes a first coil spring and a second coil spring. Each coil spring is positioned in a hole. Each coil spring has an interior end of a reduced diameter with a fastener attaching the spring to the hole. Each coil spring has an exterior end extending a short distance outside of the hole. The exterior ends of adjacent opposing coil springs are adapted to interlock and join associated components of the system when rotated with respect to each other about a common axis of rotation. The coupling components also include a cylindrical rod with opposed ends within the opposing coil springs. Each rod has an axial length greater than the length of each coil spring and less than the axial length of two holes.
