ABSTRACT:
The present invention is an adjustable support attachment for wheelchairs having vertical or horizontal arm rest members. The support, which is intended to position articles and devices within variable and convenient access to the occupant of the chair, is attached to the arm rest member by means of a mounting base, to which one end of a base tube is releasably and rotatably swivel-mounted. On the other end of the base tube is fixed an adjustable friction joint allowing angular positioning of a lower arm tube in a vertical plane. An adjustable pivoting friction joint on the radially outer end of the lower arm tube allows fully circular positioning throughout a plane perpendicular to the lower arm, in combination with an adjustable friction joint, integral with the pivotal joint, which allows angular positioning of an upper arm member within the rotatable plane including the lower arm. A releasably telescoping rod allows extension of the upper arm in discrete adjustments and an adjustable friction joint fixed at the radially outer end of the rod allows angular tilting positioning of a mounting head within the rotatable plane including the upper arm. The mounting head includes a facing plate perpendicular to the longitudinal axis of the head and a threaded mounting stud perpendicular to the plate.
