ABSTRACT:
An invalid walker comprises a lightweight, rigid frame having improved steerability derived from a combination of uniquely steerable front casters having upwardly and forwardly slanted swivel shafts together with non-swiveling rear wheels that are independently and separately controlled by separate right and left-hand brakes. Simple, effective brakes for each wheel embody a tubing section held in place solely by a return spring and the hand-operated brake cable.
