Abstract

A mouse pad support is mounted on a keyboard support that has a keyboard support arm attachable to a fixed structure such as the underside of a desk top, and a tiltable keyboard support platform thereon. A mouse pad support arm is coupled to the keyboard support arm via a rotational swivel fitting with a vertical axis for moving the mouse pad arm and mouse pad support table to any position around the keyboard in a circular arc in a horizontal plane. The height of the swivel fitting is adjustably fixed over a range. The mouse pad arm is kept in a horizontal plane because its rotational coupling to the keyboard support arm is made at an angularly fixed part on the keyboard support arm, such as on a parallelogram linkage associated with setting the elevation of the keyboard platform. The keyboard platform tilts relative to the angularly fixed part, whereby mouse position is independent of keyboard platform tilt. The mouse support arm is long enough for the mouse support table to clear the corners of the keyboard platform, but the mouse support table also is adjustably attached to the mouse pad support arm via an off-center rotational joint such that the spacing between the mouse pad and the keyboard can be adjusted by rotating the mouse support table. This off-center joint preferably employs a ball and socket universal joint with a friction adjustment, enabling an adjustable degree of tilt of the mouse pad support table as well.
