Abstract

A table attached to an invalid chair arm includes a chair frame, two arms and two sideboards. The chair frame includes on each side a back rod and a seat rod. A pivot holder is provided each at both sides of the back rod pivoted respectively to the rear end of the arm. The pivot holder is laterally inserted with a retaining lever to merely hold against the end of the arm without compromising the arm to be lifted in relation to the pivot holder allowing an invalid to sit in the chair sideways. Two holes are respectively provided vertically and laterally on the front end of the arm. The sideboard is adapted with a sleeve to receive insertion of the arm. A plurality of through holes are provided on the circumferential portion of the sleeve for a selected through hole to be aligned at the hole vertically provided on the arm and fixed in position with a positioning member, thus for the sideboard to be placed laterally on the arm.
