Abstract (en)
An aid for the blind and visually handicapped has a pistol grip at one end of straight member 10 carrying spaced ground wheels 22 on downwardly inclined end element 18. A linkage 7 is pivoted on element 18 and carries lateral resilient probes 34, 35 which can be retracted to lie rearwards by sliding knob 45 to operate linkage 7. A user holds the grip whilst walking and can sense changes in ground level and texture and vertical obstacles which deflect the probes. On release the probes return to their operative, lateral, position.
