Abstract:
1. A post driving device including: a shaft having an axially extending interior cavity, said cavity extending to a closed top end of said shaft and to a distal open bottom end of said shaft, said closed top end forming a striking surface, and said shaft having a first mounting bracket extending from an exterior wall of said shaft; a handle having an upper mounting flange mounted to said first mounting bracket by a first floating mount having a first floating region, where said first floating mount is adapted to allow said handle to rotate between at least a first and second position about an axis parallel to the longitudinal axis of the shaft and wherein said first floating mount including a rotation flange physically connected to said upper mounting flange such that said rotation flange rotates in combination with said handle, where said rotation flange includes a leading edge portion having a first end portion and a second end portion such that an end portion abuts said shaft when said handle is rotated to one of said first and second positions, thereby preventing further rotation of said handle past said one of said first and second positions; and a first dampening spring positioned between said upper mounting flange of said handle and said first mounting bracket, where said first dampening spring extends into said first floating region, and where said first dampening spring dampens vibration between said shaft and said handle.
