Patent ID: 8858103

Claim:
An adjustable keyboard comprising: a base assembly having a bottom portion configured to rest on a supporting surface, the base assembly having an upper surface with a raised central portion relative to opposing first and second lateral ends of the base assembly, to form opposing tenting angles with respect to the supporting surface during use; a first keying module having a proximal end and a distal end with respect to a user, an outer lateral end laterally opposing an inner lateral end, an upper portion and a lower portion, the upper portion being configured to operatively retain a plurality of keys thereon and the lower portion being configured to be positionable adjacent a first portion of the upper surface of the base assembly extending between the raised central portion and the first lateral end; a second keying module having a proximal end and a distal end with respect to the user, an outer lateral end laterally opposing an inner lateral end, an upper portion and a lower portion, the upper portion being configured to operatively retain a plurality of keys thereon and the lower portion being configured to be positionable adjacent a second portion of the upper surface of the base assembly extending between the raised central portion and the second lateral end; a first coupling member configured to pivotably couple the first keying module to the base assembly to allow the user to selectively pivot the first keying module toward and away from the second keying module for separating the proximal end of the first keying module from the proximal end of the second keying module and forming a desired splay angle between the inner lateral ends of the first and the second keying modules; and a second coupling member configured to pivotably couple the second keying module to the base assembly to allow the user to selectively pivot the second keying module toward and away from the first keying module for separating the proximal end of the second keying module from the proximal end of the first keying module and forming, or contributing to, the desired splay angle between the inner lateral ends of the first and the second keying modules, wherein the upper surface of the base assembly comprises a first and a second opening respectively positioned on opposing lateral sides of the raised central portion, and the first and the second coupling members include a first pivot pin and a second pivot pin, each extending through the first and the second openings, respectively, for fixedly attaching to an underside of the base assembly, and wherein the first and the second pivot pins fixedly attach to the underside of the base assembly with an anchoring structure including an aligning bracket interposed between the first and the second pivot pins for maintaining a constant distance therebetween and an anchoring bracket fixedly attaching the aligning bracket and the first and the second pivot pins to the underside.
