Abstract
A pedalling attachment for wheelchairs, to form a composite vehicle therewith, which includes an attachment frame with a pedalling mechanism and novel attachment means thereon. The attachment frame has two slidably and rotatably adjustable frames slidably insertable therein, with attachment means located at the ends thereof which grip appropriate portions of the wheelchair side frames. The attachment means are adjustable with respect to each other, to the attachment frame and to the wheelchair frames, so that a wide variety of sizes, configurations and styles of wheelchairs can be accomodated. The pedalling attachment, when attached to the wheelchair, makes the composite vehicle rigid enough to use safely on streets and highways, and to travel at highway speeds thereon for long distances.
