ABSTRACT:
A keyboard support having an adjustable keyboard shelf is provided. The keyboard support includes a base having a pair of upper and lower horizontal slots. A pair of bars connect the keyboard shelf to the slots. Inner ends of the bars slide within the slots to allow the shelf to be withdrawn from, or retracted into, the base. One of the slots includes an angled end portion allowing the bars to pivot with respect to the slots. As a consequence of the pivot action, the keyboard shelf is selectively raised or lowered. A rack and pinion mechanism is provided within the slots to limit jamming of the shelf as it is withdrawn from, or retracted into, the base. The invention provides a sturdy adjustable keyboard support inexpensively constructed of few moving parts.
