Abstract:

This invention relates to ergonomic keycaps that snap on the keys or attach directly to the keyboard of computer keyboards, word processors, electronic typewriters and other data input devices. The ergonomic keycaps are approximately the same length and width as a standard keycap but are a different height. The ergonomic keys will be positioned over the data entry keys of a computer keyboard in a manner that forms an inverted V or a wave shape. The inverted V or wave shape allows the operator's hands to be maintained in a position that should reduce repetitive stress injuries. The snap on ergonomic keycaps may be formed from flexible plastic and are designed to fit snugly onto the standard data entry keys of a keyboard. The caps design will be cup shaped and a sufficient fixation to the keys may be achieved through friction forces, vacuum forces, a combination of friction and vacuum forces, a mechanical attachment or any other suitable means know to those skilled in the industry. While intending the ergonomic keycaps to be affixed strongly to each data entry key of the computer keyboard, in one embodiment, the ergonomic keycaps may not be permanently attached and therefore may be removable.

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.
