Abstract: An ergonomic computer keyboard includes two keyboard portions, hinges connected to the respective keyboard portions enabling relative positional adjustment, carriers connected to the respective hinges, a track for supporting the carriers and enabling lateral positional adjustment of the respective carriers independently and relative to each other, and a clamp for releasably securing the track to a working surface, thereby permitting operation and positional adjustability of the keyboard portions off the working surface.

Abstract: An ergonomic computer keyboard. The computer keyboard includes two keyboard portions having keyboard keys disposed on at least two surfaces of one keyboard portion (e.g., a top side and a bottom side) and on at least one surface of the other keyboard portion (e.g., a top side). The keyboard portions are positionable for operation between a user's fingers and thumb, are interconnected, are positionally adjustable with respect to each other and are mountable on a support mechanism for operation off of a working surface.

Abstract: A laptop computer and keyboard provides an improved assembly of a central processing unit (CPU) housing, keyboard and screen, utilizing a keyboard having a right and left hand pair of keyboard portions or halves joined together in a non-planar (V-shaped or open-book shaped) arrangement along a common edge or by a connecting member. Both sides of each keyboard half preferably contain at least one key or input control, such that the entire desired array of keys is disposed about the four surfaces (i.e., two front sides and two back sides) and/or edges.
