Adapter for power tool

An adapter for coupling a tool bit to a power tool including a power tool housing, the adapter comprising:

• an adapter housing configured to be coupled to the power tool;
• an input shaft supported by the adapter housing and defining an input axis, the input shaft configured to be operably coupled to the power tool to receive rotary motion from the power tool;
• a spindle supported by the adapter housing along an output axis oriented at an angle relative to the input axis, the spindle configured to receive the tool bit;
• a transmission assembly supported by the adapter housing and operably coupled to the input shaft, the transmission assembly configured to transfer rotary motion from the input shaft to the spindle for rotation of the tool bit;
• and
• an impact assembly supported by the adapter housing, the impact assembly including a cam plate coupled to the input shaft for co-rotation about the input axis, the cam plate configured to be rotated by the input shaft to impart impacts to the tool bit.

An adapter for coupling a tool bit to a power tool, the adapter comprising:

• an adapter housing including a support frame and a top cover coupled to the support frame, the support frame formed of a first material and the top cover formed of a second material that is less rigid than the first material;
• a tool housing attachment coupled to the support frame of the adapter housing and configured to be removably coupled to the power tool;
• an input shaft supported by the adapter housing and defining an input axis, the input shaft configured to be operably coupled to the power tool;
• a spindle supported by the adapter housing along an output axis oriented at an angle relative to the input axis, the spindle configured to receive the tool bit;
• a transmission assembly supported by the adapter housing and positioned between the input shaft and the spindle, the transmission assembly configured to transfer rotary motion from the input shaft to the spindle for rotation of the tool bit;
• and
• an impact assembly supported by the adapter housing and positioned between the input shaft and the spindle, the impact assembly configured to impart impacts to the tool bit via movement of the input shaft.
