Patent ID: 7980323

Claim:
A post driving device including: a handle mounted to a shaft by a first floating mount having a first floating region and a second floating mount having a second floating region, where said first floating mount and the second floating mount allow said handle to oscillate within said first floating region and said second floating region; and a first damper spring positioned proximate the closed top end of the shaft between said handle and said shaft, where said first damper spring extends into said first floating region, and where said first damper spring dampens vibration between said shaft and said handle; a second damper spring positioned proximate the distal open bottom end of the shaft between said handle and said shaft, where said second damper spring extends into said second floating region of said second floating mount where said second damper spring dampens vibration between said shaft and said handle, and wherein the respective positioning of the first and second damper springs between the handle and shaft at the upper and lower mounting flanges isolating said handle from vibration in said shaft; and wherein said handle is floatingly attached to said first floating mount with a first nut and first bolt, where said first bolt is inserted vertically up through an aperture in said first floating mount, an aperture in said first damper spring, an aperture in said handle, and an aperture in said first nut, where said first nut secures said first bolt in place.
