ABSTRACT:
A modular arrangement for supporting any one of a wide variety of sizes of reading and other materials at a freely selectable location in relation to any selected one of a wide variety of local environments, such as chairs, sofas, tables and the like is disclosed and includes an expansible reading material holding assembly along with a plurality of support mechanisms each accepted for attachment to a different class of local environment and an arrangement for coupling the holding assembly to a select one of the support mechanisms to provide limited manual adjustability of the elevation of the holding assembly relative to the selected support mechanism as well as a limited amount of manual adjustability of the holding assembly, from vertical to horizontal, as may be preferenced by the various users. In the horizontal attitude the holding assembly functions as a table. The coupling means may include an articulated arm comprising a pair of arm members journaled together at respective first ends for unrestricted angular movement in a generally horizontal plane with one of the arms having its second end pivotably attached to the support mechanism and the other of the arms having its second end pivotably supporting the material holding assembly. The material holding assembly may include lateral extension portions and telescopic risers movable in generally orthogonal directions to expand and contract the reading material support area.
