Abstract

Abstract A generally rectangular basket, having a two-level bottom with lower level forward, is supported on a wheelchair, having horizontal foot and arm rests vertically spaced apart. Vertical legs are adjustably fixed to the forward and lower bottomed end of the basket to extend downward therefrom and engage the horizontal foot rest. Horizontal arms are adjustably fixed to opposite sides of the basket and extend rearward and over the wheelchair arm rests, the adjustable arms being recessed to fit over and around the wheelchair arms. The basket is thus displaceable only by a lifting force. The depending lower bottom increases carrying space without interfering with the line of sight of an occupant, and also without decreasing the stability of the wheelchair. A lift-off cover for the basket also acts as a horizontal support for things necessary to the limited activities of the wheelchair occupant, while the basket itself is lightened by a multiplicity of perforations for easy attachment and removable by the occupant without help.
