US Patent 7720446 Multi-position device

A multi-position device has first and second body elements configured for sliding engagement and constrained movement with respect to one another along a common plane in X, Y and XY coordinate directions for positioning the body elements in multiple different fixed positions relative to one another and for accessing one or more user interfaces carried on an outward facing surface of one body element covered by the other body element. The body elements are arranged to move relative to another from an overlapping alignment along linear, L-shaped and triangular paths in X, Y and XY coordinate directions back to the original overlapping alignment.
