International Classification:

B68G 500

US Classification:

248118

Abstract:

A keyboard storage device assembly of parallelogram shape is disclosed comprising first and second arms (18, 20), and first and second parallel platform housing arms (12, 14), each having an inner channel (42) axially receiving the arms (18, 20) therein with the arms (18, 20) moving reciprocally within the channels (42) between a retracted storage position and an extended position. A back plate (16) connects rearward ends of the arms (12, 14) and a wrist rest (26) connects forward ends of the arms (18, 20) such that the assembly may be varied in width and length. A pair of keyboard supporting plate arms (22, 24) have forward ends pivotally coupled to forward ends of the arms (18, 20) and pivot between a horizontal orientation over the arms (18, 20) into a vertical or inclined position. A keyboard positioned upon the arms (22, 24) is thus pivoted therewith and maintains an orientation such that the keys of the keyboard face forwardly and remain accessible to the user throughout the range of motion.
