Abstract
A sign stand having an improved resilient member to dissipate the torque-moment created by wind forces acting against a sign stand. The resilient member includes a coil spring, at least one plug having a helical protrusion and at least one mounting bracket. The plug is threaded into an end of the coil spring and the mounting bracket is fastened to the plug. A locking tab on the mounting bracket engages a flat ridge machined into at least one coil of the coil spring. This configuration eliminates relative rotation between the coil spring and the mounting bracket and as such, permits the effective transmission of torque into the coil spring while eliminating the potential for failure at the spring/bracket joint due to fatigue, fracture or mechanical loosening. The design of the resilient member also permits the servicing of each component as well as substantial weight reductions in the base of the sign stand.
