Patent ID: 8511693

Claim:
A mobile base for use with a power tool having a stand with four legs, where the four legs are adapted to support the power tool during normal use of the power tool, where the legs of the stand extend from the power tool toward the ground, and where the distal ends of the legs relative to the power tool are configured to rest on the ground when the power tool is in use, the mobile base comprising: two rotatable shafts, each shaft configured to be held between two legs of the stand; a link extending between the two shafts, where the link is configured so that rotation of one shaft moves the link to rotate the other shaft; a moveable actuator adapted so that movement of the actuator rotates one shaft; and wheels attached to the shafts so that rotation of the shafts lowers the wheels; where the shafts are held by the legs of the stand so that the forces of rotating the shafts and lowering the wheels are transmitted through the stand; and where rotation of the shafts lowers the wheels in such a way to raise one side of the power tool asymmetrically compared to another side of the power tool.
