Abstract
An adjustable support apparatus for supporting an object, such as a keyboard. The apparatus has a rotatable arm to which a rotatable support plate is attached. Rotation of the arm allows the height of the support plate to be adjusted. Rotation of the support plate allows its inclination to be adjusted. A constant force spring applies a varying upward moment to the support arm that approximates the varying downward weight moment applied to support arm, thereby restraining downward motion of the arm and making it easier for the user to raise the arm. Ratchet and pawl mechanisms lock the angular orientation of the support arm and the inclination of the support plate. The support plate is pivoted to the support arm so that twisting of the support plate disengages both the height and the inclination locking mechanisms.
