  • Demountable stick
    Patent number: 3963037
    Abstract: A lecturer's pointer, or a blind man's stick, is demountable into sections for easy stowing, but the sections cannot be separated since they are permanently connected by an axial cord. Pulling the cord without further guidance, causes the sections to join at spigot and socket joints, designed to minimize shake without binding. The cord is inherently elastic or is sprung and is put in tension to hold the joints rigid by a device on the head of the stick.
