Adjustable keyboard
First Claim
1. An adjustable keyboard for a typewriter, computer, or similar machine comprisinga 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, andfirst 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.

Abstract
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.

9. 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 baseplates 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, said mounting means including means for shiftably mounting at least one of said outer lateral edges to said support for motion toward and away from the other of said outer lateral edges, means for maintaining said baseplates in any one of a plurality of adjusted positions between said first and second positions, said baseplates in said first position and in said adjusted positions cooperating with said support to form a stable triangular structure, first and second sets of keys on respective ones of said baseplates, said sets collectively forming a substantial full key assembly, each key of a group of said keys comprising a key base mounted on one of said baseplates, and a key stem mounted on the key base for universal adjustment of position in three dimensions relative to the key base and a key top mounted on the stem for universal adjustment of operating position in three dimensions relative to the stem.

11. An adjustable keyboard comprising
a support, first and second sets of keys collectively forming a substantially full assembly of keys, means for mounting said sets for adjustable motion to change the planes of the sets relative to each other and relative to the support and to shift each set in its own plane, means for mounting each key of a group of said keys for individually adjustable angular and translational motion, each said key including a key cap, said means for mounting each said key comprising a key base, a longitudinally extensible key stem, and a universal connection between each end of the key stem and said key base and key cap respectively, said longitudinally extensible stem including a key sleeve and a key shaft received within said sleeve, and means interconnecting said sleeve and shaft for providing a resistance to longitudinal extension of a first magnitude and for providing resistance to longitudinal contraction of a second magnitude greater than said first magnitude.

13. An adjustable keyboard comprising
a support, a plurality of keys, means for mounting said keys to said support for individually adjustable angular and translational motion in three dimensions, each said key comprising a key base mounted to said support, a key stem having first and second mutually telescopic parts, said first part having a universal connection to said base, and a key cap having a universal connection to said second key stem part, said first and second key stem parts having a slidable and frictional interengagement to hold said parts in any one of a number of selected positions of longitudinal adjustment.
