Abstract

An adjustable support apparatus for supporting an object, such as a keyboard. The apparatus has a rotatable support arm to which a rotatable support member is attached. Rotation of the support arm allows the height of the support plate to be adjusted. Rotation of the support member allows its inclination to be adjusted. A four bar linkage mechanism ensures that the inclination of the support member remains constant despite variation in the angular orientation of the support arm. The support arm is locked from downward rotation by the interaction of a ring segment, formed on one of the links of the four bar linkage mechanism, with pins projecting from the base. The locking is disengaged by tilting the support member upward. A ratchet and pawl mechanism locks the inclination of the support member.
