Patent ID: 7720446

Claim:
Multi-position device, comprising: first and second body elements arranged in an overlapping alignment and configured for sliding engagement and constrained for non-rotational movement with respect to one another along a common plane in an X-coordinate direction, a Y-coordinate direction and an XY coordinate direction along a triangular path defined by any one of a sequence of movements in coordinate directions (+X,+Y,−X−Y), or (+X,−Y,−X+Y), or (−X,+Y,+X−Y), or (−X,−Y,+X+Y), or (+Y,+X,−X−Y), or (+Y,−X,+X−Y), or (−Y,+X,−X+Y), or (−Y,−X,+X+Y) for positioning said first and second body elements in multiple different fixed positions relative to one another for accessing one or more different portions of an outward facing surface of one of said first and second body elements covered by the other of said first and second body elements when in said overlapping alignment.
