An adjustable keyboard for typewriters, computers, and similar machines, is divided laterally into first and second sets of keys, with each set being adjustable about each of two mutually angulated axes so as to change the planes of the sets relative to each other and relative to the support, and also to allow each set to be angularly shifted in its own plane. The keys of each set are mounted for individual adjustment angularly, laterally, and in height. This allows the overall configuration of each set of keys to be individually adjusted for the convenience, physical, and operating characteristics of the arms, hands, and fingers of each operator.

An adjustable keyboard for a typewriter, computer, or similar machine comprising a support having a width extending in a lateral direction and a depth extending in a transverse direction, first and second base plates positioned in side by side relation and having adjacent lateral edges hinged together for relative pivotal motion about a transverse axis, means for mounting said baseplates to said support for folding and unfolding motion between a first position wherein each said baseplate extends upwardly from said support toward its hinged edge to form an inverted V defining a relatively small included angle between the baseplates and wherein outer lateral edges of the baseplates are spaced relatively closer to one another, and a second position wherein each said baseplate has its hinged edge closer to said support and said outer lateral edges are spaced relatively further from one another to define a relatively larger included angle; means for maintaining said baseplates in any one of a plurality of adjusted positions between said first and second positions; first and second sets of keys on respective ones of said baseplates, said sets collectively forming a substantial full key assembly, and first and second key carrier sections each mounted to a respective one of said baseplates for pivotal motion about an individual one of a pair of axes extending substantially perpendicular to respective ones of said baseplates at adjacent rear corner portions thereof, said first and second sets of keys being respectively mounted on said carrier sections whereby each set may be adjustably positioned relative to the other about said hinged edges and about said axes.
