  • Patent number: 4013881
    Abstract: A walking cane having tubular shafts in its construction through which a switch means and flashing lamp means extend and on which a cover member is secured to house said flashing lamp means. The cover member at a point 8 inches upwards from the ground end of tubular cane is of translucent substance (Lucite) thereby exposing the inner Lucite tubular "string reflector" flashing light beams. The rubber safety grip at the cane's end has a central opening permitting light beams to escape in the direction in which the cane is pointed. The batteries are housed in tandem fashion at a vantage point inside the tubular cane shaft for proper balance. The cane handle portion is easily removed for replacement of batteries and light bulb. The rubber safety grip at the ground end of the cane is removable for any adjustment of the string reflector and is moisture-proof.
