Convertible mobile computing device

A portable electronic computing device characterized by:

• a base unit;
• a display screen having means at one end thereof and arranged for slideable engagement with respective corresponding guide means located at opposite sides on said base unit for providing a first and second pivotal support point between said base unit and said display screen for movement between a closed position wherein said display screen is substantially flat and parallel with said base unit and in a downwardly facing face-to-face orientation with said base unit, a tablet position wherein said display screen is substantially flat and parallel with said base unit and in an upwardly facing orientation with respect to said base unit, and an open position wherein said display screen is angled with respect to said base unit and the angle between said base unit and said display screen being adjustable, said slideable engagement means and said guide means further being arranged for rectilinear movement with respect to one another, and
• web hinge assembly means having one end pivotally coupled to one end region of said base unit and an opposite end coupled to the display screen along a folding pivot axis extending transversely between opposite sides of the display screen and intermediate the upper end and lower end portions of the display screen for providing a third support point between said base and said display screen.

A mobile computing device characterized by:

• a base unit;
• a lid having a display screen carried on one side and a protective cover carried on the side opposite the display screen side, said lid being mechanically coupled to said base unit for movement between a closed position in which said display screen side is in a downwardly facing orientation with respect to said base unit and said protective cover is in an upwardly facing orientation with respect to said base unit and an open position, said open position including a keyboard operation position in which said display screen side is in an angled orientation with respect to said base unit and a tablet operation position in which said display screen side is in an upwardly facing orientation with respect to said base unit and said protective cover is in a downwardly facing orientation with respect to said base unit, and
• web hinge assembly means having one end coupled to a folding pivot axis defined transversely across said lid cover and to a pivot support axis defined transversely across the rear portion of said base unit, said web hinge assembly providing articulated movement of said lid between said closed position and said open keyboard and tablet positions, said lid cover further including a complementary shaped recess in its surface for receiving and nesting an upper portion of the web hinge assembly coextensive with the lid surface when said lid is in said tablet position and said closed position.
