Keyboard with adjustable splay and pronation pivot points
First Claim
1. A keyboard, comprising:
- two demi-boards, each of which include a plurality of user activated keys extending therefrom, and which define a distal side for orientation away from the user and a proximate side for orientation adjacent the user, said distal and proximate sides being joined by inwardly facing sides and outwardly facing sides;
a universal joint rotatably coupling said inwardly facing sides of the demi-boards;
a base member;
pivot point selectors slidably mounted to said demi-boards for selecting pivot points along said outwardly facing sides, about which points said demi-boards are pivotably connected to said base member and are constrained for pivotal movement about said selected pivot points between a retracted position in which said demi-boards are co-planar and said inwardly facing sides are parallel, and an extended position in which said demi-boards are splayed; and
a lift controller interconnected between said base member and said universal joint for adjusting and controlling the height of said universal joint and the pronation of said demi-boards relative to said base member, which pronation becomes more pronounced as said pivot selectors are positioned toward said proximate sides.

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.

10. An adjustable keyboard for data input, comprising a base member having a longitudinal base surface extending through said base member;
-
a first demi-board having a distal side for orientation away from the user and a proximate side for orientation adjacent the user; a plurality of user activated keys extending from said first demi-board, said keys facing away from said base member; a second demi-board having a distal side for orientation away from the user and a proximate side for orientation adjacent the user; a plurality of user activated keys extending from said second demi-board, said keys facing away from said base member; wherein said distal and proximate sides of said first and second demi-boards are joined by respective first and second inner facing sides and respective first and second outer facing sides; a universal joint rotatably coupling said first and second inner facing sides of said first and second demi-boards; first and second pivot selectors slidably mounted to said outer sides for selecting a pivot point along each of said respective outer sides, about which points said respective first and second demi-boards are pivotably connected to said base member and are constrained for pivotal movement about said respective selected pivot points between a retracted position in which said first and second inner sides are parallel and an extended position in which said first and second demi-boards are splayed and pronated; a lift controller interconnected between said base member and said universal joint for adjusting and controlling the elevation of said universal joint and the pronation of said first and second demi-boards relative to said base member, which pronation becomes more pronounced, and splay less pronounced, as said pivot selectors are moved toward said proximate ends of said outer sides. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An adjustable keyboard assembly for data input, comprising a base member having a longitudinal support surface, said base member having a distal side intended for orientation away from the user and a proximate side for orientation adjacent the user and first and second sides joining said distal and proximate sides;
-
a first demi-board having a distal side for orientation away from the user, a proximate side for orientation adjacent the user, and first and second ends joining said distal and proximate sides; a plurality of user activated keys extending from a face of said first demi-board, said keys facing away from said base member; a first rail hingedly attached to said first side of said first demi-board and having distal and proximate ends corresponding respectively to said distal and proximate sides of said first demi-board, said first demi-board further having an array of pivot points longitudinally arranged along said rail, said base member having a first array of pivot points corresponding to said array of said pivot points on said first rail; a first pivot selector slidably secured to said first rail for pivotably connecting a selected one of said first rail pivot points to a corresponding one of said base member pivot points so that said first rail is connected to said base member and is constrained for pivotal movement about said selected pivot point between a retracted position in which said first rail is parallel to said first side of said base member and an extended position in which said first rail forms an acute angle with respect to said first side of said base member; a second demi-board having a distal side for orientation away from the user, a proximate side for orientation adjacent the user, first and second ends joining said distal and proximate sides; a plurality of user activated keys extending from a face of said second demi-board, said keys facing away from said base member; a second rail hingedly attached to said second side of said second demi-board and having distal and proximate ends corresponding respectively to said distal and proximate sides of said second demi-board, said second demi-board further having an array of pivot points longitudinally arranged along said rail, said base member having a second array of pivot points corresponding to said array of said pivot points on said second rail; a second pivot selector slidably secured to said second rail for pivotably connecting a selected one of said second rail pivot points to a corresponding one of said base member pivot points so that said second rail is connected to said base member and is constrained for pivotal movement about said selected pivot point between a retracted position in which said second rail is parallel to said second side of said base member and an extended position in which said second rail forms an acute angle with respect to said second side of said base member;
a universal jointrotatably coupling said demi-boards at the intersection of said respective inner and distal sides of said first and second demi-boards; a lift controller interconnected between said base member and said universal joint for controlling the elevation of said first and second demi-boards between a first position and a second position; and wherein said first and second pivot point selectors are independently adjustable and, together with said lift controller, are operable for adjusting the splay and pronation of said first and second demi-boards, wherein said pronation becomes more pronounced and splay becomes less pronounced as said pivot selectors are located toward said proximate ends of said rails and away from said distal ends of said rails. - View Dependent Claims (20, 21, 22, 23, 24, 25)
