  • Patent number: 6463947
    Abstract: A directionally illuminated walking aid has a walking-aid shaft (1) that is predeterminedly transparent with, an internal light (4, 20) directed vertically from a top reflector (2) towards a bottom cap (3) from which vertical reflectors (5) may be extended upwards for reflecting light (6) forward and/or radially from intermediate the top reflector and a bottom reflector (8). Opposite and/or intermediate the vertical reflectors are light rings (15, 16, 17) in non-reflector portions of the walking-aid shaft to allow emission of light reflected from the vertical reflectors. The walking-aid shaft is a leg of a cane (9), crutch (10), walker (11) or other walking aid. An electrical source (13) in the walking aid is switched selectively from proximate a handle (39) of the walking aid. The internal light can be steady, pulsatile, incandescent, fluorescent or other type of electrical light. The current source can be storable, chargeable and/or plug-in.
