Abstract

A monitor support arm assembly is disclosed comprising a support arm (14), a socket member (38) affixed to a remote end of the support arm, the socket member creating a concave central cavity (84), and an elongate slot (74) extending through support arm and communicating with the socket member cavity (84). An adjustable tray (12), having a concave lower surface (54), seats within the socket member cavity (84) and has an elongate slot (52) extending therethrough that overlaps the first mentioned support arm and socket member slot (74). A friction pad (40) of arcuate shape is affixed to an underside of the support arm (14) and has a through slot (92) that aligns with the support arm slot (74), and a downwardly facing arcuate bearing surface (88). A locking screw shall (98) extends through the friction pad slot (92), and the overlapping support arm and socket member slot (74), and through the tray slot (52) to assemble the components together. Adjustment of the angular position and pitch of the tray (12) is accomplished by loosening the screw, and pivoting the tray concave lower surface (54) within the socket member cavity. The screw shaft (98) travels along the overlapping slots as the adjustment is made and along the friction pad arcuate outer surface (88), which serves to alter the direction in which the screw shaft (98) projects as it moves along the slots (92,74) so that the shaft (98) is always perpendicular to the portion of the bearing surface (54) through which it extends.
