ABSTRACT:
A pyramid shaped ergonomic keyboard comprised of three sets of keys or three keypads. A front keypad faces the operator and contains number keys, specialty keys, function keys and a trackball/mouse. The left and right keypad are at approximately a 45.degree. angle positioned in a tripod fashion substantially meeting at a vertex and substantially forming a pyramid with the front keypad. The left keypad and right keypad each contain the key in standard QWERTY layout (albeit split and positioned at a 45.degree. angle). The front, left and right keypads may be mounted or attached to a support frame. The keypads are adjustable in a horizontal and vertical manner relative to each other allowing individual adjustment of each keypad for the convenience of the operator. Protruding from the frame between the front keypad and the left keypad and the front keypad and the right keypad are handrests to support the hands when typing. The handrests may be adjusted in a horizontal and vertical manner to provide greater support and comfort for the operator while typing. Both hands are in a natural and relaxed position, substantially facing together with wrists straight and the thumbs up. The handrests further facilitate maintaining the wrists in a substantially neutral or relaxed arc. The resulting natural and relaxed hand and wrist positions reduce the likelihood of repetitive stress injuries such as carpal tunnel syndrome, flexor tendinitis, extensor tendinitis, and DeQuervain's Disease.
