  • Ergonomic keyboard for a portable computer which is moveable between two positions
    Patent number: 5754395
    Abstract: An apparatus and method for providing a portable computer keyboard (6) with a forward and downward slope. The device and method include a linkage assembly (8) for automatically moving the keyboard into an inclined position when the display module (22) of the computer is opened into its operating configuration. The linkage assembly is further adapted to automatically move the keyboard into a substantially parallel orientation relative to the computer housing (10) when the display module is closed into the carrying or carrying configuration. A disabling mechanism (80) is coupled to the linkage assembly for preventing the linkage from moving the keyboard between the carrying and operating positions as the display module is opened and closed.
