ABSTRACT:
An impact deflection absorber and stabilizer for providing an interface between two items, surfaces, etc. permitting regulated and controlled travel (energy absorption) along its longitudinal axis and constraining motion in all other directions. An energy absorbing spring is positioned within a housing comprised of two cylindrical mating surfaces forming a friction surface therebetween. A collar clamp joins the two cylinders together and adjustably controls the amount of friction between the two surfaces thereby providing control of the energy absorbing capability of the device. The clamp also has the effect of strengthening the device along non-longitudinal axes, such that all axes have a resonant or fundamental frequency higher than that along the longitudinal or primary axis whereby the device will yield longitudinally regardless of what direction the forces are emanating from.
