ABSTRACT:
A hinge mechanism for a portable apparatus having a keyboard base and a display unit pivotable between open and closed positions. The hinge mechanism comprises a rod disposed within a bearing and connected to a bracket mounted on the base. A spring is disposed over the base to provide a compression force against the bearing in the axial direction of the rod to provide frictional engagement between the rod and bearing to hold the display in the open position. The outer wall of the rod is tapered to cooperate with the tapered inner wall of the bearing.
