Abstract
The present invention relates to systems and methods for damping the impact and rebound forces associated with the use of elongated poles. One embodiment of the present invention relates to a supportive pole system including an elongated shaft, hand receiving member, tip, and force absorbing system. The force absorbing system includes a damping member externally disposed on the elongated shaft between the elongated shaft and either the hand receiving member or the tip. The damping member includes an elastic material such as elastomer that rebounds in response to a compression force. The damping member may include a plurality of stages configured to include independent damping force response characteristics. The force absorbing system may further include a rebound air dampener within the hand receiving member for controlling the rebound force characteristics of the damping member.
