ABSTRACT:

FIELD OF THE INVENTION
This invention relates to keys of computer keyboards and the like and particularly to the keys of a keyboard mounted on the backside of the notebook computer or game box.
BACKGROUND AND INFORMATION DISCLOSURE
Along with the tremendous growth in the development and marketing of personal computers and computer games, there has been a widespread occurrence of various forms of a malady classified as “repetitive motion syndrome”. (RMS). This malady is especially prevalent among users of keyboards wherein long periods of typing lead to such conditions as “carpal tunnel syndrome” and strain in the ligaments and tendons of the wrists. The problem is exacerbated by the unnatural position of the hands while typing in which the wrists are turned so that the palms of the hand face downward while the fingers move across the board activating the keys. The wrists are twisted when the hand is in this orientation.
The patent literature contains a number of references intended to address this problem. For example, U.S. Pat. No. 5,502,460 discloses a keyboard having two sections of keys tilted with respect to one another.
U.S. Pat. No. 5,515,305 to Register discloses a PDA having a chord keyboard on the backside of the chassis for forming single alphanumeric indicia by depressing combinations of keys.
U.S. Pat. No. 5,645,277 to Cheng discloses hand held control units with finger operating surfaces.
U.S. Pat. No. 549,037 discloses a tiltable keyboard.
U.S. Pat. No. 5,645,277 to Cheng discloses hand held units with finger operating surfaces.
U.S. Pat. No. 5,515,305 to Register et al discloses a computer having a chord keyboard mounted on front and rear surfaces of the PDA computer. The problem with this keyboard is that each alphanumeric datum is entered by pressing a combination of keys and therefore the depression of the keys is not consistent with the layout of the typical keyboard to which the user has become accustomed.
However, there is no thought given to a conventional keyboard with 40 keys positioned on a keyboard in an arrangement that reduces stress on the wrists as effectively as the present invention while permitting the user to manipulate his fingers according to his training to operate state of the art keyboards.
SUMMARY
It is an object of this invention provide a keyboard for a notebook, personal data assistant (PDA), or game box. The keyboard is positioned on a surface on the side of the chassis facing away from the user so that the fingers and hands are in a “natural” position. In the contest of this specification, “natural” position is defined as meaning that the palms are turned upward facing the underside of the box when typing thereby minimizing strain on the wrists, the palms are turned upward facing the underside of the box when typing thereby minimizing strain on the wrists. The keys are arranged in a “standard” position meaning that they are arranged on the keyboard in the same arrangement as the standard keyboard so that the user has the same “feel” of location that occurs when the keyboard is on the top surface of the chassis thereby eliminating the strain caused by twisting the wrist to type in the state of the art position.
