Abstract

Abstract A walking cane for the blind or the aged which emits warning flashes of light is disclosed. The cane is shaped to have a tubular shaft and a handle having an angled section extending laterally from one end of the shaft to be grasped by the hand of an user. Provided on the cane are two spaced apart light sources, one positioned at intermediate portion of the length of the shaft and the other positioned at such portion behind the user's hand as to be exposed backwardly of the person holding the cane. The former light source is utilized to give a warning by being flashed on and off to the others moving forward upon or passing across the person holding the cane, while the latter to give the same to the others approaching behind that person. Accordingly, these two longitudinally spaced light sources are cooperative to arouse all other persons in the vicinity to take notice of the person holding the cane and therefore to enhance the security of the person holding the cane.
