Computer keyboard
First Claim
1. A keyboard for a computer for operating with hands of a user disposed in a prehensile position, said keyboard comprising:
- a keyboard body,keyboard means located at an upper surface of said keyboard body and having keys for depressing by movement of fingers of a user in a first direction;
spacing means mounted at a forward edge of said keyboard means for operating by movement of a thumb of the user;
activating means mounted on said keyboard body on a surface transverse to said upper surface, located centrally with respect to a length of said keyboard means for movement in all directions to control all directions of movement of a cursor on a display screen of the computer by movement of at least one thumb of a user in a second direction transverse to said first direction for engagement of said keyboard means and said activating means by the user'"'"'s hands disposed substantially in a prehensile alignment position with the thumb opposed to the fingers in a substantially grasping motion between the thumb and fingers of the user to cause actuation of said keyboard means and said activating means while the thumb and fingers are in close proximity in prehensile alignment when using the keyboard and whereby ulnar abducted deviation and hand-pronation are reduced.

Abstract
A keyboard for a computer is used with the hands of a user disposed substantially in a prehensile position with the thumb opposed to the fingers in a grasping position. The keyboard includes a first slanting keyboard surface for locating keys to be activated by a user'"'"'s left hand adjacent and sloping downwardly away from a second slanting keyboard surface for locating keys to be activated by a user'"'"'s right hand. The first and second keyboard surfaces are joined at a peaked central edge forming a V-shape which slopes downwardly toward a user and laterally away from the user. Twelve numbered function keys are positioned in a circular array toward an outward end of the first keyboard surface. A keypad for locating numeric keys is positioned toward an outward end of the second keyboard surface. A cursor control unit on a front surface of the keyboard, below the space bar, is used for controlling the movement of a cursor and is operated by the thumb of the user in a direction transverse to the direction of operation of the keys. The space bar may also be operated in the transverse direction or at a selected angle. Ulnar abducted deviation and hand-pronation are reduced by using the keyboard, thus reducing the incidence of carpal tunnel syndrome.

17. A keyboard for a computer, said keyboard comprising:
-
a keyboard body, first activating means located on at least one first upper surface of said keyboard body for actuation by movement of fingers of a user; and second activating means fixed and projecting from a second surface of said keyboard body, located centrally with respect to a length of said first activating means for movement in all directions to control all directions of movement of a cursor on a display screen of the computer by at least one thumb of the user, said second surface extending transverse to said at least one first surface for engagement of said first activating means and said second activating means by hands of a user positioned in a prehensile alignment so that a substantially grasping motion between the at least one thumb and fingers of the user can cause actuation of both said first activating means and said second activating means while said at least one thumb and fingers are in a close proximity in prehensile alignment. - View Dependent Claims (18)

19. A keyboard for a computer, said keyboard comprising:
-
a keyboard body, first activating means located on first and second upper slanting keyboard surfaces of said keyboard body comprising keys for depressing by fingers of a user'"'"'s left and right hands respectively, said first and second slanting keyboard surfaces joined at a peak central edge forming a V-shape which slopes downwardly toward the user and laterally away from the user; and second activating means on a third surface of said keyboard body, located centrally with respect to a length of said first activating means for movement in all directions to control all directions of movement of a cursor on a display screen of the computer by at least one thumb of the user, said third surface extending transverse to said first and second upper slanting keyboard surfaces for engagement of said first activating means and said second activating means by hands of a user disposed in a substantially prehensile alignment position with substantially straight wrist during use so that a substantially grasping motion between the at least one thumb and fingers of the user can cause actuation of said first activating means and said second activating means while said at least one thumb and fingers are in a close proximity in prehensile alignment. - View Dependent Claims (20, 21)

22. A keyboard for a computer for operating with hands of a user disposed in a prehensile position, said keyboard comprising:
-
a keyboard body, keyboard means located at an upper surface of said keyboard body comprising first and second transverse surfaces with a common edge located centrally with respect to a length of said keyboard means, said common edge located through the entire width of said keyboard means, and having keys for depressing by movement of fingers of a user in a first direction; spacing means mounted at a forward edge of said keyboard means for operating by movement of a thumb of the user; activating means mounted on said keyboard body on a third surface transverse to each of said first and second transverse surfaces, located centrally with respect to a length of said keyboard means for rotational movement of said activating means in all directions to control all directions of movement of a cursor on a display screen of the computer by movement of at least one thumb of a user in a second direction transverse to said first direction for engagement of said keyboard means and said activating means by the user'"'"'s hands disposed substantially in a prehensile alignment position with the thumb opposed to the fingers in a substantially grasping motion between the thumb and fingers of the user to cause actuation of said keyboard means and said activating means while the thumb and fingers are in close proximity in prehensile alignment when using the keyboard and whereby ulnar abducted deviation and hand-pronation are reduced.

23. A keyboard for a computer, said keyboard comprising:
-
a keyboard body, first activating means located on at least one first upper surface of said keyboard body comprising first and second transverse surfaces with a common edge located centrally with respect to a length of said first activating means, said common edge located through the entire width of said first activating means, for actuation of said first activating means by movement of fingers of a user; and second activating means fixed and projecting from a third surface of said keyboard body, located centrally with respect to a length of said first activating means for rotational movement in all directions to control all directions of movement of a cursor on a display screen of the computer by at least one thumb of the user, said third surface extending transverse to said first and second transverse surfaces for engagement of said first activating means and said second activating means by hands of a user positioned in a prehensile alignment so that a substantially grasping motion between the at least one thumb and fingers of the user can cause actuation of both said first activating means and said second activating means while said at least one thumb and fingers are in a close proximity in prehensile alignment.
