Abstract
An impact mechanism for an impact tool having a housing with a housing longitudinal axis, wherein the impact mechanism includes an impact mechanism longitudinal axis that is offset and substantially perpendicular to the housing longitudinal axis. The impact mechanism includes a gear carrier adapted to be driven by a motor of the impact tool to rotate about the impact mechanism longitudinal axis, a hammer slidably coupled to the gear carrier and rotatable about the impact mechanism longitudinal axis, the hammer includes a radial surface with a hammer lug extending therefrom, and an intermediate bit adapted to receive impact force from the hammer lug and transfer impact force to a tool bit.

An impact hammer tool, comprising:
- a housing having a bore extending in a first direction;
- a motor disposed in the housing and having a motor axis that is substantially perpendicular to the first direction;
- a tool bit operably coupled to and extending from the housing;
- a hammer operably coupled to the motor;
- and
- an intermediate bit slidably disposed in the bore and adapted to receive an impact force from the hammer when the motor is operated and impact the tool bit.
An impact hammer tool, comprising:
- a housing having a bore extending in a first direction;
- a motor disposed in the housing;
- a tool bit operably coupled to and extending from the housing;
- and
- an impact mechanism operably coupled to the motor and having an impact mechanism longitudinal axis that is substantially perpendicular to the first direction, wherein the impact mechanism includes an intermediate bit having opposing first and second ends, and the first end has a conical type shape, wherein the intermediate bit is slidably disposed in the bore and the first end is adapted to apply an impact force to the tool bit when the motor is operated, and wherein the bore has a shape that cooperatively matches the conical type shape of the first end.
