  • Publication number: 20020117589
    Abstract: A typing support is provided as a part of a typing station including a keyboard. The typing support includes a frame having a track and a keyboard support for engagement with a keyboard, a pair of wrist supports, and mounting members on which the wrist supports are carried. The mounting members provide support for the wrists of the typist which allow pivotal movement of one and preferably both hands during typing, and also translational movement along the longitudinal axis of the track. At least one of the wrist supports may be retained in a stationary position relative to the track by a retainer. The relative height or inclination of the keyboard can be adjusted by adjustment feet. The keyboard support may include a support member which pivots relative to a base to adjust the height of the keyboard received thereon, and may also keep a sheet of paper or the like in an upright position for viewing during typing.
