Abstract

A neutral-positioning keyboard/wrist support device (10) is described. The support device comprises a wrist support member (12) having a cushion means (46) mounted thereon with the support member being adjustably movable with respect to first vertical slots (28,30) provided in a base member (14) to provide various vertical height elevations for the cushion means above a support surface (20). A keyboard (16) is supported on a platform (18) having a proximal end (84) that is engagable with pairs of tabs (92,94 and 96) extending from a bracket portion (98) of the wrist support to provide for adjusting the slope of the platform and thereby the associated keyboard. The vertical height of the cushion means is spaced above the keyboard. This enables the typist to have her hands in a "neutral" posture resting on the cushion means with the wrists positioned such that the hands are approximately in a horizontal plane to reach the keyboard keys.
