Springy Trunk

Type: component
PROBLEM

Rigid poles snap or topple in earthquakes, high winds, and impact events.

SOLUTION

The Springy Trunk is the seismic and wind-resilient configuration of the Trunks pole platform, incorporating a multi-laminate glass-fiber and carbon-fiber composite flex joint assembly at the base collar that allows the pole shaft to deflect up to 15 degrees off vertical in any radial direction under dynamic loading without permanent deformation, recovering to within 0.2 degrees of true vertical upon load removal through stored elastic strain energy in the flex joint matrix. The flex joint is rated for 50,000 full-deflection cycles before scheduled replacement and is designed to be field-swappable without removing the pole from its foundation. The shaft above the flex joint is a standard-geometry tubular section compatible with all Trunk-series clamp collars, cross-arms, and Uni-Adapter mounts. The Springy Trunk was validated against seismic zone 4 requirements and sustained simulated Richter 7.2 event loading in accelerated shake table testing without loss of structural integrity or attached load.
