First Claim
1. A portable computer comprising:
- a base having an upper surface, a bottom surface, and spaced first and second side edges, a rear end portion, and a front end portion having a front peripheral base edge;
a display member having a front surface having a display screen for displaying information, a back surface, and first and second peripheral display edges joining said front and back surfaces;
a U-shaped frame body mounting said display member to said base, said frame body including;
first and second spaced lateral arm portions positioned outwardly of said side edges of said base and said peripheral display edges when said display member is lowered onto said base; and
a rigid connecting portion extending along said rear end portion of said base between said arm portions having a curved tubular cross section that reinforces the U-shaped frame body to provide stability, rigidity, and reduce torsional stresses during movement of the frame body and forms a concave pocket to receive a substantially conforming convex portion of said base at the rear end portion of said base;
said frame body being pivotally coupled to said first display edge for rotation of said display member relative to said first arm portion, and pivotally coupled to said first side edge of said base at said rear end portion of said base for rotation of said frame body relative to said base, said rigid curved tubular connecting portion of said frame body sliding concentric with and relative to said convex portion of said base during rotation of said frame body relative to said base;
said first arm portion being provided first and second friction hinges and said second arm portion being provided with no hinges, said first spaced lateral arm portion being pivotally coupled to said first peripheral edge of said display member by a first friction hinge and to said base by a second friction hinge; and
said second arm portion being provided with an aperture forming an internal conduit from said base to said second arm portion which houses an electrical connector for coupling said screen housed in said display member to electrical components housed in said base.

Abstract
A portable computer. The computer includes a base, a display member, and an arm assembly coupling the display member to the base. The arm assembly includes a pair of spaced arm portions and a rigid connecting portion extending between the arm portions. The arm portions each have a first end pivotally coupled to the base edge for movement of the arm assembly between a closed position with the arm portion substantially parallel to the base and an open position with the arm portion oriented at an angle relative to the base, and a second end pivotally coupled to the display edge for pivotal movement of the display member relative to the arm portion to move the display member between a plurality of positions relative to the arm member.

19. A portable computer comprising:
-
a base having an upper surface, a bottom surface, and spaced first and second side edges, a rear end portion, and a front end portion; a display member having a front surface having a screen for displaying information, a back surface, and first and second peripheral display edges joining said front and back surfaces; a keyboard disposed on said base upper surface; an infrared wireless communication device for communicating between a processor internal to said portable computer and an external infrared transmitter; a U-shaped frame body mounting said display member to said base, said frame body including; first and second spaced lateral arm portions positioned outwardly of said side edges of said base and said peripheral display edges when said display member is lowered onto said base; and a rigid connecting portion extending along said rear end portion of said base between said arm portions having a curved tubular cross section that reinforces the U-shaped frame body to provide stability, rigidity, and reduce torsional stresses during movement of the frame body and forms a concave pocket to receive a substantially conforming convex portion of said base at the rear end portion of said base; said frame body being pivotally coupled to said first display edge for rotation of said display member relative to said first arm portion, and pivotally coupled to said first side edge of said base at said rear end portion of said base for rotation of said frame body relative to said base, said rigid curved tubular connecting portion of said frame body sliding concentric with and relative to said convex portion of said base during rotation of said frame body relative to said base; said first arm portion being provided first and second friction hinges and said second arm portion being provided with no hinges, said first spaced lateral arm portion being pivotally coupled to said first peripheral edge of said display member by a first friction hinge and to said base by a second friction hinge; and said second arm portion being provided with an aperture forming an internal conduit from said base to said second arm portion which houses an electrical connector for coupling said screen housed in said display member to electrical components housed in said base; said electrical connectors being carried by a ribbon; said ribbon being threaded through a path in said second arm portion which minimizes stresses exerted on said ribbon during rotation of said frame body relative to said base, and rotation of said display member relative to said arm member; said stress minimizing path including providing a complete first loop formed in said ribbon as said ribbon enters said arm portion from said display member, said first loop selectively becoming tighter and looser as said display is pivoted relative to said arm portion, preventing said electrical connectors from crimping; and said stress minimizing path further including providing a second loop before said ribbon enters said base, said second loop selectively becoming tighter and looser as said arm portion is pivoted relative to said base, preventing said electrical connectors from crimping;
said second loop reducing stresses on said ribbon during manipulation of said frame body;said first and second friction hinges are configured for rotation of said frame body between a plurality of configurations including; (i) a first closed configuration in which said display screen is configured substantially parallel to said base upper surface and facing toward said base upper surface in a closed position to cover said keyboard and said arm portions of said frame body are positioned adjacent said side edges of said base; (ii) a second configuration in which said display screen is configured substantially parallel to said base upper surface for inputting data to said portable computer and covers said keyboard and said arm portions of said frame body are positioned adjacent said side edges of said base; (iii) a third configuration in which said keyboard accessible for inputting data to said portable computer and said display screen is configured for viewing by a user while accessing said keyboard; and (iv) a fourth position in which said display screen is configured at an acute angle relative to said base upper surface for presentation to others and a first portion of said peripheral base edge and a portion of said peripheral display edges are disposed to support said portable computer on a surface with an outwardly directed display screen for presentation.
