ABSTRACT:
A data input keyboard apportioned between two demi-boards, the splay and pronation of which may be adjusted. Each of the demi-boards include a plurality of user activated keys extending therefrom, and define a distal side for orientation away from the user and a proximate side for orientation adjacent the user. The distal and proximate sides of the demi-boards are joined by inwardly facing sides and outwardly facing sides. A universal joint rotatably couples the inwardly facing sides of the demi-boards. Pivot point selectors are slidably mounted to the demi-boards for selecting pivot points along the outwardly facing sides, about which points the demi-boards are pivotably connected to the base member and are constrained for pivotal movement about the selected pivot points between a retracted position in which the demi-boards are co-planar and the inwardly facing sides are parallel and an extended position in which the demi-boards are splayed and pronated.
