Patent ID: 7445191

Claim:
A locking system mounting a mirror with a motor vehicle between undefined and defined adjusted positions comprising: a support arm supporting said mirror between first and second ends; a brace secured with said vehicle supporting a first end of said support arm between fixed defined rotatable adjustable positions; a locking device comprising interconnected first and second extensions, located generally vertically of said brace, said first extension being secured with said vehicle and said second extension being secured with said second end of said support arm; a first conical surface having a central opening carried by said first extension and a second conical surface having a central opening carried by said second extension; said first and second conical surfaces being sized to fit in a snug manner one within the other over an extent of said conical surfaces; a locking member extending through said openings to engage outer surfaces of said first and second extensions, said locking member being operative in a first position to urge said conical surfaces into generally fixed relative positions and in a second position to allow undefined three dimensional movement between said conical surfaces; wherein, movement between said conical surfaces of said locking device brings about movement of said second end of said support arm resulting in slight adjustments between undefined positions of said mirror without movement of said first end from a defined fixed position.
