  • Patent number: 5152730
    Abstract: A walking aid comprising a movable framework mounted on wheels is provided for handicapped persons that may lose their balance when walking, so that they need not have to rely upon a companion for support when practicing walking after an injury, etc. This aid can be used while the walker is manipulating crutches or canes. The walker may easily enter the walking aid into a resident position without the necessity to climb over framework structure. It is freely moved by body contact without the use of hands on its wheel mounts. The resident walker loosely wears a harness that is removably affixed to the framework in a manner that will prevent a fall by bearing the walker's weight in an upright position, but which permits walking with little encumberment. The walking aid is moved on its wheels over the floor by means of the harness with little effort, and needs no hands for grasping or support during walking.
