A walking stick has an integral personal alarm. Two types of alarm system may be used in suitably adapted walking sticks, preferably situated between the handle and the stick. One Type is a gas cylinder powered alarm, operated by finger pressure through the on alarm control aperture in the side of the upper part of the stick. Another Type is a battery powered alarm which is similarly operated by the finger. The alarm may be situated inside a suitable housing in the top of the stick. |
