Abstract
Abstract An ergonomic keyboard support device for a computer keyboard having a substantially planar key upper plane, comprising a keyboard support having an operator-proximal keyboard support edge and a substantially planar keyboard support top surface; a support bar for maintaining wrist and forearm support during keyboard operations; and a computer mouse platform for holding a computer mouse and for writing by a keyboard operator and for maintaining wrist support during mouse operations. The support bar, which is connected to the top surface of the keyboard support across the operator-proximal keyboard support edge, has a substantially planar bar top surface. The mouse platform is movably positioned upon the planar top surface of the keyboard support and has a substantially planar top surface that is substantially in the same plane as the planar bar top surface. A wedge under the support platform upon a carriage plate connected to articulated linkage tilts the keyboard support at approximately 8° relative to the horizontal so that in turn the keyboard frame is tilted to an angle wherein the upper plane defined by the keyboard keys is horizontal along with the top planes of the support bar and the mouse platform. The articulated linkage can tilt the device to a plurality of angles and positions.
