Patent attributes
A tool is provided in the form of an angled and/or offset ratchet wrench extension. The angles may be selected, but in a preferred embodiment, a ratchet extension provides a right angle drive. The tool comprises a socket driver that is adapted to be connected to a socket and a rotatable drive shaft rotatably mounted within a housing. A first direction changing transmission is provided near the end for converting the rotatable drive shaft motion to rotary motion to drive the socket driver at the specified angle. A ratchet wrench is connected to the distal portion of the rotary drive shaft. In a second embodiment, a second direction changing transmission is located near the distal portion of the rotatable drive shaft for converting the rotary motion of a ratchet wrench to the rotary motion of the rotatable drive shaft. The length of the extension may be adjustable. In another preferred embodiment, a chain drive and sprocket are used as the drive and angle changing direction transmission.
