Patent ID: 7568288

Claim:
A right angle attachment for a power hand tool of the type which has an elongated generally cylindrical housing containing a motor having a motor output shaft extending from a nose end thereof, the housing having a generally cylindrical nose end portion that is concentric with said motor output shaft, said nose end portion providing a structure on which said attachment can be mounted, said attachment comprising: a housing having a mounting end and a distal end, with the mounting end having a cylindrical opening sized to snugly fit on the nose end portion of the tool housing; said housing having an input shaft journaled in bushings and having an engaging recess at one end portion for engaging a drive shaft that is driven by the motor output shaft, and an attached gear at the opposite end; said housing having an output shaft journaled in bushings, said output shaft being configured to rotate a tool attached to said distal end, and having a gear attached to its opposite end portion; said input shaft gear engaging said output shaft gear at a generally 90 degree angle so that said motor output shaft drives said accessory output shaft; a magnet mounted on said output shaft and an electrical circuit mounted in said attachment housing adjacent said magnet for producing power, said circuit comprising at least one light producing device, and a printed circuit board having conductive lines and being in sufficiently close proximity to said magnet so that rotation of said magnet causes the magnetic field of the magnet to induce a current in inductors for driving said light producing device, said circuit further comprising two inductors and two LEDs connected in parallel with one another, said two LEDs being connected such that the anode of one is connected to the cathode of the other, said inductors being located at approximately the same radius relative to the axis of said output shaft, but arcuately spaced from one another by approximately 90 degrees; and a lens in said housing adjacent said light producing device for admitting light to the exterior of said housing toward a tool attached to said distal end.
